PART I


Except for historical information, the following description of Mobile Mini's
business contains forward-looking statements which involve risks and
uncertainties. Our actual results could differ materially from those set forth
in these forward-looking statements as a result of a number of factors,
including those set forth below in Item 1 in this report under the heading "Risk
Factors."


ITEM 1. DESCRIPTION OF BUSINESS.


GENERAL


We are the nation's largest provider of portable storage solutions through a
lease fleet of nearly 26,000 portable storage units. We have 12 branch offices
in seven states. Our products provide attractive, accessible temporary storage
for a diversified customer base of over 28,000 customers, including Wal-Mart,
Motorola, Frito Lay, Holiday Inns, Target, City of Phoenix and the Department of
Defense. These customers use our products for excess inventory, construction
site storage, records and document storage and a host of other applications. We
obtain our portable storage units by purchasing used ocean-going containers
(ISOs), which we refurbish and modify, and by manufacturing our own units. We
offer a wide range of products in varying lengths and widths with an assortment
of differentiated features such as our patented security systems, multiple
doors, electrical wiring and shelving. In addition to our leasing operations, we
sell new and used portable storage units and provide other ancillary services.


In 1996, we initiated a strategy of focusing on leasing rather than selling
portable storage units. We have been expanding our lease fleet since that time.
We believe that leasing our units is a more attractive business opportunity for
the following reasons:

- Our leases have an average life exceeding 20 months and produce
predictable, recurring revenues.

- Our average rental rates recover the cost of our investment within an
average of 26 months.

- Our portable storage units have useful lives exceeding 20 years with
residual values of about 70%.

- Leasing provides us incremental operating margins of approximately 60%
once the fixed costs of the branch have been covered.


As a result of our shift to a leasing focus, we have successfully increased our
size and profitability. Since 1996, our lease fleet has increased 128.1%, our
leasing revenue has increased 135.8% to $36.5 million and our operating income
has increased 190.9% to $13.3 million. Additionally, we have increased our
operating margin from 11.4% in 1995 to 25.3% in 1998. We plan to continue to
focus on the leasing of our portable storage units to an increasing customer
base through an expanding branch network.


INDUSTRY OVERVIEW


The storage industry consists of two principal segments, fixed self-storage and
portable storage.


The fixed self-storage segment consists of permanent structures away from
customers' locations. Fixed self-storage is used primarily by consumers to
temporarily store excess household goods. According to the Self Storage Almanac,
the fixed self-storage market exceeded $10 billion in 1997. This segment is
highly fragmented but includes several large national companies such as Public
Storage and Shurgard Storage Centers.


The portable storage segment is different from the fixed self-storage segment
because it brings the storage solution to the customer's own location and
addresses the need for temporary secure storage with immediate access. The
advantages of portable storage include convenience, immediate accessibility,
price and higher security. In contrast to fixed self-storage, the portable
storage segment is primarily used by businesses. This segment is highly
fragmented with no national participants. Although there are no published
estimates of the size of the portable storage segment, we believe there is
increasing market awareness of the advantages of portable


-1-

storage. We believe, therefore, that there is substantial potential to increase
the size of the portable storage segment. Refurbished ISO shipping containers
and over-the-road trailers are the primary products used to provide portable
storage.


In 1998, approximately 78% of our leasing customers were businesses,
approximately 15% were consumers and approximately 7% were government,
institutional and other.


Our products also service the mobile office industry. This industry provides
temporary office space and is estimated to exceed $2 billion. We also recently
introduced records storage units. These units provide portable, secure records
storage. This industry is experiencing significant growth as businesses continue
to generate substantial paper records that must be kept for extended periods.


COMPETITIVE STRENGTHS


We attribute our success in the portable storage business to the following
competitive strengths:


Market Leadership. We are the nation's largest lessor of portable storage units.
We have a lease fleet of nearly 26,000 portable storage units and are the
largest provider of portable storage solutions in a majority of our markets. We
believe we have created name recognition and brand awareness, and that "Mobile
Mini" is associated with high quality portable storage products and superior
service. We have achieved significant growth in new markets by capturing market
share from competitors and by creating demand among businesses and consumers who
were previously unaware of the availability of our products to meet their
storage needs.


Superior, Differentiated Products. We offer a broad range of portable storage
products in varying lengths and widths to better meet our customers' temporary
storage needs. Our manufacturing and refurbishing capabilities enable us to
offer products that our competitors are unable to match. Most competitors offer
only standard eight foot wide ISO shipping containers in 20, 40 or 45 foot
lengths. Our portable storage units range in size from five to 48 feet in length
and eight to 10.5 feet in width. Our manufactured 10-foot wide units, introduced
in 1998, provide 40% more useable storage space than the standard eight-foot
wide ISO shipping containers offered by our competitors. Our products also have
patented locking systems, multiple door options, and electrical wiring, shelving
and other customized features.


Customer Service Focus. We believe that the portable storage business is highly
service intensive and essentially local. We have trained our sales force to
focus on all aspects of customer service from the sales call onward. We
differentiate ourselves by providing flexible lease terms and timely delivery of
units. Our sales people work out of our branch locations rather than from our
headquarters. This allows them to interact directly with customers, better
understand local market needs and develop each market in response to those
needs. We conduct on-going training programs for our sales force to assure high
levels of customer service and awareness of local market competitive conditions.
Our customized software system increases our responsiveness to customer
inquiries and enables us to efficiently monitor our sales force's performance.
As a result of this customer service focus, we enjoy high levels of repeat
business and word-of-mouth referrals.


Diverse Customer Base. During 1998, we served more than 28,000 customers across
a wide range of industries including retailers, wholesalers, commercial
businesses, contractors, consumers, governmental agencies and hospitals and
schools. Our two largest customers accounted for only 4.3% and 2.1% of our 1998
lease revenues. We believe that our diverse customer base reduces our
susceptibility to economic downturns in our markets or in any of the industries
in which our customers operate. Customer diversity also demonstrates the broad
application of our products and the opportunity for us to create future demand.


Customized Management Information Systems. We have made substantial investments
in our management information system as part of our effort to optimize fleet
utilization, improve financial performance and provide customer data used to
target markets for additional revenue opportunities. Our MIS systems enable us
to carefully monitor the size, mix, utilization and rental rates of our lease
fleet by branch on a daily basis. We have maintained the average annual
utilization rate of our lease fleet above 87% over the last three years while
growing the size of the lease fleet by 128.1% to nearly 26,000 units. Our
systems also capture relevant customer demographic and usage information which
we use to target new customers within our existing and new markets. Our
headquarters and each branch are linked through a PC-based wide area network
that provides real-time transaction processing and detailed reports on a branch
by branch basis.


-2-

Flexibility Afforded By Manufacturing Capability. We design and manufacture our
own portable storage units and also refurbish and modify used ISO shipping
containers. This capability allows us to offer a wide range of products to meet
our customers' needs, charge premium lease rates and gain market share from our
competitors that have more limited product offerings. Our manufacturing
capability also provides us with an alternative source of supply to support our
growth and to utilize whenever prices increase for used ISO shipping containers.


GROWTH STRATEGY


We intend to pursue the following growth strategy:


Focus on Core Portable Storage Leasing Business. We intend to continue to focus
on growing our core leasing business because it provides predictable, recurring
revenues and high margins. We believe there is substantial demand for our
portable storage units throughout the United States. For example, in Los
Angeles, our largest market, we have increased the number of portable storage
units in our lease fleet from 4,211 units at the end of 1996 to 7,135 units at
the end of 1998. Our focus on leasing has allowed us to achieve annual growth
rates of 33.1% in leasing revenues and 42.8% in operating income over the past
three years.


Increase Penetration in Existing Markets. We intend to continue to focus on
increasing the number of portable storage units leased from our existing
branches to both new and repeat customers. We will attempt to create new demand
for leased units in all of our markets. We have historically been able to
generate strong internal growth within our existing markets. From 1995 through
1998, we generated compounded annual leasing revenue increases of 30.8% in the
eight markets where we operated during all four years. We achieved these high
levels of internal growth by increasing awareness of our products through our
targeted marketing programs and advertising while rapidly expanding our lease
fleet.


Accelerate Branch Expansion. We believe our branch model can be introduced to
multiple markets throughout the United States and intend to pursue this
opportunity. We have identified many markets in the United States where we
believe demand for portable storage units is underdeveloped. These markets are
currently being served by small, fragmented industry competitors. In 1998, we
began our expansion strategy by entering four new markets, three by acquisition
and one by start-up. Whenever feasible, we enter a new market by acquiring the
storage units and leases of an operating business in order to generate immediate
revenues to cover overhead. Where there are no quality acquisitions available to
us, we plan to enter targeted markets through start-up branches.


Develop New Products. We attempt to develop new products and new applications
for our products through an active research and development effort. For example,
in 1998 we introduced a 10-foot wide storage unit that has proven to be a
popular product with our customers. In addition, we recently completed the
design of a records storage unit which provides highly secure, on-site easily
accessible storage. We are beginning to market this unit as a records storage
solution for semi-active records. We believe our design and manufacturing
capabilities increases our ability to service our customers' needs and the
demand for our portable storage solutions.


PRODUCTS


We provide a broad range of portable storage products to our customers to meet
their varying needs. Our product types and their features are as follows:


Portable Storage Products

- Refurbished and Modified Storage Units. We purchase used ISO shipping
containers from leasing companies or brokers. These containers are eight
feet wide, 8'6" to 9'6" high and 20, 40 or 45 feet long. After acquiring
an ISO container, we refurbish and modify it. Refurbishment typically
involves cleaning, removing rust and dents, repairing floors and
sidewalls, painting, adding our signs and installing new doors and our
patented locking system. Modification typically involves splitting
containers into 5, 10, 15, 20 or 25 foot lengths.


-3-
5
- Manufactured Storage Units. We manufacture portable storage units for
our lease fleet and for sale. We do this at our manufacturing facility
in Maricopa, Arizona. We can manufacture units up to 12 feet wide and 50
feet long and can add doors, windows, locks and other customized
features. Typically, we manufacture "knock-down" units which we ship to
our branches and assemble there. This method of shipment is less
expensive than shipping fully assembled storage units.

- Records Storage Units. We recently completed the design of a proprietary
portable records storage unit that we are now marketing Our units enable
customers to store their records at their location for easy access or at
one of our facilities. Our units are 10.5 feet wide and are available in
12, 23 and 34 foot lengths. They feature high security doors and locks,
electrical wiring, shelving, folding work tables and air filtration
systems. We believe our product is a cost-effective alternative to mass
warehouse storage and provides fire and water damage protection.


Mobile Offices

- We manufacture mobile office units that range from 10 to 40 feet in
length. We offer mobile office units in various configurations,
including office and storage combination units that provide a 10 or
15-foot office with the remaining area available for storage. Office
units are equipped with electrical wiring, heating and air conditioning
units, phone jacks, carpet and/or tile, proprietary doors and windows
with security bars. We believe the advantages of our office units
include ground accessibility and their high security, all-steel design.


We purchase used ISO shipping containers and refurbish and modify them at our
facilities in Arizona, California and Texas. We also manufacture new portable
storage units at our Arizona facility. We believe we are able to purchase used
ISO shipping containers at competitive prices because of our volume purchases.
In 1998, we purchased and refurbished about 6,200 used ISO shipping containers
and manufactured approximately 4,000 portable storage units and mobile offices.
The used ISO shipping containers we purchase are typically about 10 to 12 years
old. We believe our portable storage units and mobile offices have useful lives
of at least 20 years if properly maintained, with residual values of over 70% of
their original cost.


LEASE TERMS


Our leases have an average initial term of 8.1 months and provide for the term
to continue at the same rental rate on a month-to-month basis until the customer
cancels the lease. The average duration of our leases has been 20 months. Our
average monthly rental rate was $118 in 1998. Most of our portable storage units
rent for $60 to $180 per month although large custom-designed units may rent for
as much as $350 per month. Our mobile offices typically rent for $110 to $325
per month. The average utilization of our lease fleet was 87.0% in 1998 and
85.7% in 1997. Each lease provides that the customer is responsible for the cost
of delivery at lease inception and pickup at lease termination. The leases also
specify that the customer is responsible for any damage done to the unit beyond
ordinary wear and tear. Our customers may purchase a damage waiver from us. This
provides us with an additional source of revenue. For the past 3 years, our cost
to repair and maintain our portable storage units has averaged 2.0% of our lease
revenues. Repainting the outside of storage units is the most frequent
maintenance item.


BRANCH OPERATIONS


We locate our branches in regions with attractive demographics and strong growth
prospects. Within each market, we have located our branches in areas that allow
for easy delivery of portable storage units to our customers. We also seek
locations that are very visible from high traffic roads as an effective way to
advertise our products and our name.


Each branch has a Branch Manager who has overall supervisory responsibility for
all activities of the branch. Branch Managers report to one of our three
Regional Managers. Incentive bonuses based upon branch performance are a
substantial portion of the compensation for both Branch and Regional Managers.


Each branch has its own sales force, a transportation department that delivers
and picks up portable storage units from customers, and an office manager. Each
branch has delivery trucks and forklifts to load, transport and unload units and
a storage yard staff


-4-

responsible for unloading and stacking units. Units are stored by stacking them
three high to maximize usable ground area. Each branch also has a fleet
maintenance department to maintain the branch's trucks, forklifts and other
equipment. The majority of our branches provide on-site storage of portable
storage units leased to customers.


The following table shows information about our branches:

Oklahoma City, Oklahoma Leasing and sales 6 acres 1998

Albuquerque, New Mexico Leasing and sales 2 acres 1998

Denver, Colorado Leasing and sales 4 acres 1998



SALES AND MARKETING


We have 60 people at our branches and 7 people at our headquarters that conduct
sales and marketing on a full-time basis. We believe that by locating our sales
and marketing staff in our branches, they are better able to understand the
portable storage needs of our customers and provide the high levels of customer
service.


Our sales and marketing force provides information about our products to
prospective customers by handling inbound calls and by initiating cold calls. We
have on-going training programs for our sales and marketing force covering all
aspects of leasing and customer service. Our branches are connected to one
another and to headquarters through our network processing system. This enables
the sales and marketing staff to share leads and other information and permits
the headquarters staff to monitor and review sales and leasing productivity on a
branch by branch basis. Our sales and marketing force is compensated primarily
on a commission basis. We restructured our commission program in 1996 when we
changed our focus to leasing rather than selling portable storage units.


We advertise our products in the yellow pages and use a targeted direct mail
program. In 1998, we mailed about 6 million product brochures to customers and
prospective customers. These brochures describe our products and the advantages
of our portable storage solutions.

CUSTOMERS


During 1998, more than 28,000 customers leased our portable storage units,
compared to about 21,000 in 1997. Our customer base is diverse and consists of
businesses in a broad range of industries. During 1998, our largest customers
accounted for only 4.3% of our leasing revenues and our next largest customer
accounted for only 2.1% of our leasing revenues.


We target customers who have long-term or seasonal storage needs. Customers use
our portable storage units for a wide range of purposes. The following provides
an overview of our customers and how they use our portable storage units:
Retail, including drug, grocery, shopping and strip mall stores, hotels,
restaurants, dry cleaners and service stations, 40%; Construction, including
general, electrical, plumbing and mechanical contractors, landscapers and
companies who build residential homes, 31%; Consumers, including homeowners for
home storage or moving related storage, 15%; Commercial, including companies
that do not sell to the open public, distributors, trucking and utility
companies, 7%; Government and Institutions, including Federal, State, County and
Local agencies, military, reservations, hospitals and educational facilities,
6%; and Other, including farming, agriculture, finance and insurance, real
estate brokers and film production, 1%. Our retail and wholesale customers in
1998 included Walmart(R), KMart(R), Target(R) and Frito Lay(R). We believe our
construction customer base is characterized by a wide variety of contractors who
are associated with original construction and capital improvements in the
commercial, institutional, residential and industrial areas.


MANUFACTURING


We build new portable storage units, mobile offices and custom-designed
structures at our Maricopa, Arizona manufacturing plant. We also refurbish and
modify used ISO shipping containers at this plant. Our workers cut and shape
steel for new units and then weld and paint them. These workers also install
custom features. We have about 350 manufacturing workers in this plant. We
manufactured and refurbished about 10,200 portable storage units in 1998. Many
of our manufactured portable storage units are "knock down" units which we ship
to our branches for final assembly. We can ship up to twelve, 20-foot containers
on a single flat-bed trailer. In comparison, only two to three assembled 20-foot
ISO shipping containers can be shipped on a flat-bed trailer. This reduces our
cost of transporting units to our branches. We believe we can expand the
capacity of our Maricopa plant at a relatively low capital cost.


We purchase raw materials such as steel, vinyl, wood, glass and paint which we
use in our manufacturing and refurbishing operations. We typically buy these raw
materials on a purchase order basis. We do not have long-term contracts with
vendors for the supply of any raw materials.


Our manufacturing capacity serves to protect us to some extent from price
increases for used ISO shipping containers. Used ISO shipping containers vary in
price from time to time based on market demand, which is related to the volume
of shipping of containerized freight. Whenever the price of used ISO shipping
containers increases substantially, we can increase our manufacturing volume and
reduce the number of used containers we buy and refurbish.


MANAGEMENT INFORMATION SYSTEMS; FLEET MANAGEMENT


We use a customized management information system for lease fleet management and
our targeted sales and marketing efforts. This system consists of a wide-area
network that connects our headquarters and all of our branches. Headquarters and
each branch can enter data into the system and access data on a real-time basis.
Our system generates weekly management reports by branch of leasing volume,
fleet utilization, lease rates and fleet movement as well as monthly profit and
loss statements by branch and company wide. These reports allow management to
monitor each branch's performance on a daily, weekly and monthly basis. We track
each portable storage unit by its serial number. Lease fleet and sales
information is entered in the system daily at the branch level and verified
through periodic physical inventories by branch employees. Branch salespeople
use the system to track customer leads and other sales data and to obtain
information about current and prospective customers.


-6-
8
COMPETITION


In all of the markets where we operate, we face competition from several local
companies and usually one or two regional competitors. Our competitors include
lessors of portable storage units, used over-the-road trailers and other
structures used for temporary storage. To a lesser degree, we also compete with
fixed self-storage facilities, such as U-Haul, Public Storage, Shurgard Storage
Centers, and various smaller competitors. We compete primarily in terms of
security, convenience, product quality, availability, customer service and
price. Some of our competitors have less debt, greater market share and greater
financial resources and pricing flexibility than we do. Sometimes, a competitor
will lower its lease rates in one of our markets to try to gain market share.
This may require us to reduce our lease rates as well, which could reduce our
profitability in those markets.


In addition to competition for customers, we face competition in purchasing used
ISO shipping containers. Several types of businesses purchase used ISO shipping
containers, including various freight transportation companies, freight
forwarders and commercial and retail storage companies. Some of these companies
have greater financial resources than we do. As a result, if the number of
available containers for sale decreases, these competitors may be able to absorb
an increase in the cost of containers, while we could not. If container prices
increase substantially, we may not be able to manufacture enough new units to
grow our fleet. These price increases also could increase our expenses and
reduce our earnings.


Competition in our markets may increase significantly in the future. New
competitors may enter our markets and may have greater marketing and financial
resources than we do. This may allow them to gain market share at our expense.
Increased competition may cause us to lower lease rates and reduce profit
margins. If our competitors have greater financial resources, they may be able
to sustain these pricing pressures better than we can.


EMPLOYEES


As of March 15, 1999, we had about 900 full-time employees. Our employees are
represented by the following major categories:


Management 38
Administrative 134
Sales 60
Manufacturing 503
Drivers and Storage Unit Handling 165


Our employees are not represented by a labor union and we consider our relations
with our employees to be good.


RISK FACTORS


Our business involves a high degree of risk. You should carefully consider the
risks and uncertainties described below and the other information in this
report. If any of the following risks and uncertainties actually occur, our
business, results of operations and financial condition could be materially
adversely affected.


This report also contains forward-looking statements that involve risks and
uncertainties. Discussions in this report concerning forward-looking statements
are under the headings "Risk Factors," "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Business." Our actual
results could differ materially from those anticipated in the forward-looking
statements as a result of certain factors, including risks described below.


-7-

Risks of Managing Our Growth


Our future performance will depend in large part on our ability to manage our
planned growth. Our recent growth has strained our managerial, human and other
resources. Our anticipated future growth could place additional strains on these
resources while we try to integrate the operations of our acquisitions and new
branches and adjust to operating in new markets. To successfully manage this
growth, we must continue to improve our operating, financial and other internal
procedures and controls and add employees. We also must effectively motivate,
train and manage our employees. We cannot be sure that we can assimilate our
recent and future acquisitions and new branches into our operations. If we do
not manage our growth effectively, some of our acquisitions and new branches may
fail and we may decide to close unprofitable locations. Closures would likely
result in additional expenses which would cause our operating results to suffer.


Our Company Operates With a High Amount of Debt


Our operations are very capital intensive and we operate with a high amount of
debt relative to our size. Typically, we borrow 80% to 90% of the cost of a
finished portable storage product. We have a credit facility with a group of
banks. Under the credit facility, we can borrow up to $75 million on a revolving
loan basis, which means that amounts repaid may be reborrowed. As of March 15,
1999, we had borrowed approximately $59.3 million under our credit facility, and
had $10.7 million available for further borrowing based upon the agreement's
borrowing base formula. Our amount of debt makes us more vulnerable in the event
of a downturn in the general economy or in the industries we serve. In addition,
amounts we borrow under our credit facility bear interest at a variable rate.
Because these rates change with prevailing interest rates, higher prevailing
interest rates would increase the amount of interest we have to pay on our debt.
This could have a material adverse effect on profitability and our ability to
grow as quickly as we are planning.


Under our credit facility, we must comply with a variety of covenants and
restrictions. These include minimum tangible net worth, operating income, and
storage unit utilization rate requirements. The terms of our credit facility
also limit our capital expenditures, acquisitions, additional debt and
repurchases of our common stock, and prohibit us from paying cash dividends.
These covenants and restrictions could limit our ability to respond to market
conditions and restrict our planned growth. In addition, if we fail to comply
with these covenants and restrictions, the lenders have the right to refuse to
lend us additional funds, and they may require early payment of amounts we owe
them. In addition, upon default, our lenders may foreclose on most of our
assets, including our portable storage unit fleet. If this happens, we may be
unable to fund our operations and could not expand our leasing activities.


Additional Debt or Equity Financing Will Be Necessary to Sustain Our Growth


Our ability to grow will depend in part on our ability to obtain additional debt
financing and to raise additional equity capital by issuing additional shares of
our stock. We cannot be sure, however, that we will be able to obtain the
necessary debt or equity financing on economically advantageous terms. Also,
additional debt financing or the sale of additional equity securities may cause
the market price of our common stock to decline. If we are unable to raise
additional debt or equity financing on acceptable terms, we may have to curtail
our growth by delaying lease fleet expansion or new branch openings.


Our Operating Results and Financial Performance May Fluctuate


Although demand from some of our customers is somewhat seasonal, our operations
as a whole have not been very seasonal. Demand for leases of our portable
storage units is stronger from September through December due to retailers
needing to store more inventory for the holiday season. Our retail customers
usually return leased units to us early in the following year. This has caused a
lower utilization rate for our lease fleet during the first quarter of each
year.


-8-
10
Our results of operations may vary significantly from period to period due to a
variety of factors which affect demand for our units. These factors include:


- general economic and industry conditions;

- availability and cost of used ISO shipping containers;

- changes in our marketing and sales expenditures;

- pricing pressures from our competitors;

- market acceptance of our portable storage units, particularly in new
markets we enter;

- the number of new branches we acquire and start-up and when we do so;
and

- when we introduce new products or when our competitors do so.


There Are Risks to Our Strategy


Our strategy is to grow in part through branch expansion, either by acquisitions
or new branch openings. This strategy involves a number of risks, including the
following:


- we may not find suitable acquisition targets or locations for new
branches;

- competition for acquisition candidates could cause purchase prices to
significantly increase;

- we may fail to adequately integrate the businesses we acquire into our
existing business structure;

- the costs of completing an acquisition and then integrating and
operating the business could be higher then we expect; and

- we may acquire a branch or start one in a new market that turns out not
to have enough demand for our portable storage units to make the branch
profitable.


A Slowdown in the Economy Could Reduce Leasing Demand by Some of Our Customers


These industries tend to be cyclical and particularly susceptible to slowdowns
in the overall economy. If an economic slowdown occurs, we are likely to
experience less demand for leases and sales of our products from customers in
the construction and retail sales industries. This could have a material adverse
effect on our business and results of operations.


There Is Uncertainty and Risk in the Supply and Price of Used ISO Containers


We purchase, refurbish and modify used ISO shipping containers as we add units
to our fleet. The availability of these containers depends in part on the state
of international trade and overall demand for containers in the ocean cargo
shipping business. When international shipping increases, the availability of
used ISO shipping containers for sale decreases, and the price of the containers
that are available typically increases. Conversely, an oversupply of used ISO
shipping containers may cause container prices to fall. Our competitors may then
lower the lease rates on their storage units. As a result, we may need to lower
our lease rates to remain competitive. This would decrease our revenues and our
earnings.


Several types of businesses purchase used ISO shipping containers. These include
various freight transportation companies, freight forwarders and commercial and
retail storage companies. Some of these companies have greater financial
resources than we do. As a result, if the number of available containers for
sale decreases, these competitors may be able to absorb an increase in the cost
of containers, while we could not. If used ISO shipping container prices
increase substantially, we may not be able to manufacture enough new units to
grow our fleet. These price increases also could increase our expenses and
reduce our earnings.


The amount we can borrow under our credit facility depends in part on the value
of the portable storage units in our lease fleet. If the value of our lease
fleet declines, we cannot borrow as much. Therefore, we may be unable to add as
many units to our fleet as we would like. Also, we are required to satisfy
several covenants with our lenders that are affected by fluctuations in the
value of our lease fleet. We would breach some of these covenants if the value
of our lease fleet drops below specified levels.

We Face Significant Competition From a Variety of Businesses


In all of the markets where we operate, we face competition from several local
companies and usually from one or two regional companies. Our competitors
include lessors of storage units, used over-the-road trailers and other
structures used for portable storage. To a lesser degree we also compete with
conventional fixed self-storage facilities. We compete primarily in terms of
security, convenience, product quality and availability, lease rates and
customer service. Some of our competitors have larger lease fleets, less debt,
greater market share, and greater financial resources and pricing flexibility
than we do. Sometimes, a competitor will lower its lease rates in one of our
markets to try to gain market share. This may require us to lower our lease
rates as well, which could reduce our profitability in those markets.


Competition in our markets may increase significantly in the future. New
competitors may enter our markets and may have greater marketing and financial
resources than we do. This may allow them to gain market share at our expense.
Increased competition may cause us to lower lease rates and reduce profit
margins. If our competitors have greater financial resources, they may be able
to sustain these pricing pressures better than we can. Prolonged price
competition is likely to have a material adverse affect on our business and
results of operations.


There Are Risks From Fluctuations in the Supply and Costs of Raw Materials We
Use in Manufacturing


We also manufacture portable storage units. In our manufacturing process, we
purchase steel, vinyl, wood, glass and other raw materials from various
suppliers. We cannot be sure, however, that an adequate supply of these
materials will continue to be available on terms reasonably acceptable to us.
The raw materials we use are subject to price fluctuations that we cannot
control. The cost of raw materials will have a significant effect on our
operations and earnings. Rapid increases in material prices are difficult to
pass through to customers. If we are unable to pass on these higher costs, our
results of operations could decline significantly. If raw material prices
decline significantly, we may have to write down our raw materials inventory
values. If this happens, our results of operations and financial condition would
decline.


Zoning Laws Could Restrict The Use of Our Storage Units


Most of our customers use our storage units to store their goods on their
property. Officials in certain cities and towns have informed some of our
customers that local zoning laws do not permit them to keep our portable storage
units on their property or do not permit portable storage units unless located
out of site behind their business. If our units cannot be located in a
significant number of cities and towns in our markets due to zoning laws or
other regulations, our business could be adversely affected.


We Must Attract and Retain Personnel in a Highly Competitive Labor Market


Our future success will depend on our ability to attract, retain and motivate
employees with various skills, as well as semi-skilled and unskilled labor for
our branches and manufacturing plants. Competition for all types of employees,
including skilled and unskilled laborers, is intense. A shortage in the pool of
employees could require us to increase our wage and benefits to attract and
retain enough employees. An increase in our labor costs, or our inability to
attract, retain and motivate employees, would likely have a material adverse
effect on our business and results of operations.


-10-
12
We Are Subject to Governmental Regulation


We manufacture, refurbish or modify portable storage units at four locations.
Our facilities are subject to regulation by several federal and state government
agencies, including the Occupational Safety and Health Administration (OSHA)
and the Environmental Protection Agency.


Our facilities are subject to worker safety and health laws and regulations
administered by OSHA. Our employees work with metal presses, heavy materials and
welding equipment, and the possibility of injury is quite high. This means that
OSHA is likely to inspect our facilities from time to time. We have on-going
training and safety programs designed to minimize injuries. If we were found to
be out of compliance, we may have to pay fines or even reconfigure our
operations at considerable cost. New OSHA regulations may be enacted in the
future and could increase our cost of manufacturing and refurbishing portable
storage units.


Various environmental laws and regulations may expose us to liability for past
or present spills, disposals or other releases of hazardous or toxic substances
or waste products. This may be the case even if we did not know about or cause
the spill or contamination. We generate waste and by-products from our painting
operations, potentially exposing us to liability for spills or contamination.
Federal or state agencies may impose more stringent disposal regulations for
paint waste and by-products. This also could increase the costs of manufacturing
and refurbishing portable storage units.


The Market Price of Our Stock Is Volatile


The market price of our common stock has fluctuated for a number of reasons,
including quarterly variations in our operating results and changes in earnings
estimates by analysts. The stock market in general also has experienced extreme
price and volume fluctuations which have affected the stock price of many
companies including ours. These fluctuation may adversely affect the market
price of our common stock.


We Rely Heavily on a Few Key Employees


We are substantially dependent on the personal efforts and abilities of Richard
E. Bunger, our Founder and Chairman, Steven G. Bunger, our President and Chief
Executive Officer, and Lawrence Trachtenberg, our Executive Vice President and
Chief Financial Officer. The loss of any of these officers or our other key
employees could have a material adverse effect on our business and results of
operations. We do not have employment agreements with any of these people.


ITEM 2. DESCRIPTION OF PROPERTY.


We own our branch locations in Dallas, Texas and Oklahoma City, Oklahoma. We
lease all of our other branch locations. All of our major leased properties have
remaining lease terms of at least five years, and we believe that satisfactory
alternative properties can be found in all of our markets if necessary.


We own our manufacturing facility in Maricopa, Arizona, approximately 30 miles
south of Phoenix. This facility is eight years old and is on approximately 45
acres. The facility includes nine manufacturing buildings, totaling
approximately 158,000 square feet. These buildings house our manufacturing,
assembly, refurbishing, painting and vehicle maintenance operations.


We lease our corporate and administrative offices in Tempe, Arizona. These
offices have 28,800 square feet of space, which we believe is enough to meet our
needs for the next several years. The lease term is through December 2000. We
believe we will be able to renew this lease.


-11-
13
ITEM 3. LEGAL PROCEEDINGS.


We are a party to routine claims incidental to our business. Most of these
claims involve alleged damage to customers' property while stored in units they
lease from us. We carry insurance to protect us against loss from these types of
claims, subject to deductibles under the policy. We do not believe that any
current litigation, individually or in the aggregate, is likely have a material
adverse effect on our business or results of operations.


ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.


The annual meeting of the stockholders of the Company was held on October 2,

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


OVERVIEW


Since 1996, we have transitioned to primarily leasing portable storage units
from primarily selling them. This has caused the composition of our revenues and
expenses to change. Leasing revenues as a percentage of our total revenues
increased to 69.2% in 1998 from 54.0% in 1997 and 42.1% in 1996. From the end of
1993 to the end of 1998, we increased the number of portable storage units in
our lease fleet from 5,400 to 26,000. This is an average annual growth rate in
units of approximately 37%.


Our leasing revenues include all rent we receive for our portable storage units.
Our sales revenues include sales of portable storage units and other structures
to customers. Our other revenues consist principally of charges for the delivery
of the portable storage units we sell. Our principal operating expenses are (1)
cost of sales; (2) leasing, selling and general expenses; and (3) depreciation
and amortization, primarily depreciation of the portable storage units in our
lease fleet. Cost of sales includes both our cost to buy, refurbish and modify
used ISO shipping containers and our cost to manufacture portable storage units
and other structures. Leasing, selling and general expenses include advertising
and other marketing expenses, commissions and corporate overhead for both our
leasing and sales activities. Typically, annual repairs and maintenance expenses
on our leased units have averaged approximately 2.0% of lease revenues. We
expense our repair and maintenance costs as incurred, and we include them in
leasing, selling and general expenses. Our portable storage units are
depreciated on the straight-line method over our units' estimated useful life of
20 years, with salvage values estimated at 70% of our original cost.

1998 COMPARED TO 1997


Total revenues in 1998 increased by 14.3% to $52.7 million from $46.1 million in
1997. Leasing revenues in 1998 increased by 46.6% to $36.5 million from $24.9
million in 1997. These increases resulted from a 42.9% increase in the average
number of portable storage units on lease and a 2.6% increase in the average
rent per unit. We added three branches in 1998 by acquisition in Las Vegas,
Oklahoma City and Denver. These three new branches generated an increase in
units leased of 71.1% in 1998 and accounted for 14.8% of our increase in leasing
revenues. The branches that we opened before 1998 accounted for 84.2% of our
increase in leasing revenues and Albuquerque, our start-up location, contributed
1.0%. Our revenues from the sale of units decreased by 23.9% to $15.6 million in
1998 from $20.5 million in 1997. This reflects our focus on leasing rather than
selling portable storage units. This decrease was also caused by our decision in
1998 to curtail the sale of telecommunication shelters and discontinue our
dealer program.


Cost of sales decreased to 68.7% of sales revenues in 1998 from 70.9% of sales
revenues in 1997. During 1998, we paid less for both used ISO shipping
containers and the steel we use to manufacture portable storage units. We also
produced more portable storage units at our manufacturing plant in 1998 than in
1997. These factors caused the higher gross margin on portable storage unit
sales in 1998.


As a percentage of revenues, leasing, selling and general expenses increased 49%
to $25.7 million in 1998 from $20.6 million or 45% in 1997. We had higher
leasing-related expenses because of the 42.9% increase in the number of units on
lease, higher commissions because of our higher leasing volume and $1.4 million
of expenses associated with the three branches we acquired and the one branch we
started in


-16-
18
1998. These expenses totaled 3.9% of our leasing revenues in 1998. Both acquired
and start up branches initially have lower profit margins until the branches'
fixed operating costs are covered by higher leasing volumes.


Depreciation and amortization expenses increased by $631,000 to 5.5% of total
revenues in 1998 from 4.9% in 1997. This increase resulted from our larger lease
fleet, additional equipment needed for manufacturing and maintaining the lease
fleet and other equipment added at our branches.


Our operating margin increased to 25.3% in 1998 from 18.9% in 1997 principally
because we focused on leasing rather than selling our portable storage units and
because leasing, selling and general expenses decreased as a percent of leasing
revenues. As a result, income from operations increased by 53.4% to $13.3
million in 1998 from $8.7 million in 1997.


Interest expense increased by 17.1% to $5.9 million in 1998 from $5.0 million in
1997 as a result of higher average debt outstanding during 1998. Our average
debt outstanding increased by 29.0%, consisting of $6.9 million of 12% Senior
Subordinated Notes issued in October 1997 and an additional $21.3 million of
borrowings under our credit facility. We used this debt financing primarily to
expand our lease fleet. The weighted average interest rate declined to 8.7% in
1998 from 9.5% in 1997, excluding amortization of debt issuance costs. Including
amortization of debt issuance costs, the weighted average interest rate was 9.6%
in 1998 and 10.6% in 1997.


We reported net income in 1998 of $4.5 million, or $0.53 per diluted share of
common stock, compared to net income in 1997 of $2.2 million, or $0.32 per
diluted share of common stock. These increases were primarily because of our
higher leasing revenues in 1998 and the decrease in leasing, selling and general
expenses per unit on lease in 1998. Our effective tax rate was 40.0% for both
1998 and 1997. We had a 23.8% increase in the weighted average number of common
and common share equivalents outstanding in 1998 because of exercise of warrants
we had issued in 1994 and common stock issued in connection with the
acquisitions.


1997 COMPARED TO 1996


Total revenues in 1997 increased by 8.6% to $46.1 million from $42.4 million in
1996. Leasing revenues in 1997 increased 39.1% to $24.9 million from $17.9
million in 1996. These increases resulted from a 25.6% increase in the average
number of portable storage units on lease and an increase of $1.0 million from
our loss limitation waiver program which we introduced in 1997. Our sales
revenues from the sale of portable storage units and other structures decreased
by 13.1% because we began focusing on leasing rather than selling and because we
discontinued selling modular buildings. This decrease was partially offset by a
$2.2 million increase in revenues from the sale of telecommunication shelters.


During 1997, we implemented price increases on the portable storage units we
sell. This and our discontinuation of selling low margin modular buildings
caused a substantial increase in our gross margin on sales during 1997. As a
result, cost of sales as a percentage of sales decreased to 70.9% during 1997
from 84.4% during 1996.


Leasing, selling and general expenses increased by 34.2% to $20.6 million in
1997 from $15.3 million in 1996. We attribute this increase to higher
leasing-related expenses because we had more units on lease, higher commissions
because of our higher leasing volume and increased expenses to develop the
infrastructure we needed for our planned future growth. These expenses totaled
82.8% of our leasing revenues in 1997, compared to 85.8% in 1996.


Depreciation and amortization expenses increased by $540,000 to 4.9% of total
revenues in 1997 from 4.0% in 1996. This increase resulted from our larger lease
fleet, additional equipment needed for manufacturing and maintaining the lease
fleet and other equipment added at our branches.


We recorded a restructuring charge in 1996 of $700,000 because we discontinued
manufacturing modular buildings. There was no similar charge in 1997.


-17-
19
Our operating margin increased to 18.9% in 1997 from 11.2% in 1996 principally
because we focused on leasing rather than selling portable storage units and
because we substantially improved our gross margin on sales of units. Income
from operations increased by 83.4% to $8.7 million in 1997 from $4.7 million in
1996.


Interest expense increased by 29.3% to $5.0 million in 1997 from $3.9 million in
1996 as a result of our higher average debt outstanding during 1997. Our average
debt outstanding increased by 40.8% and consisted of $6.9 million of 12% Senior
Subordinated Notes issued in October 1997 and an additional $9.5 million of
borrowings under our credit facility. We used this debt financing primarily to
expand our lease fleet. The weighted average interest rate declined to 9.5% in
1997 from 10.2% in 1996, excluding amortization of debt issuance costs.
Including amortization of debt issuance costs, the weighted average interest
rate was 10.6% in 1997 and 11.6% in 1996.


In 1996, we prepaid approximately $14.1 million of debt and capital lease
obligations at the time we entered into our credit facility. As a result, we
recognized an extraordinary charge to earnings in 1996 of $410,000, or $0.06 per
common share, net of the benefit of income taxes.


We reported 1997 net income of $2.2 million, or $0.32 per diluted share of
common stock, compared to 1996 net income before extraordinary item of $481,000,
or $0.07 per diluted share of common stock. These increases were primarily
because of the 39.1% increase in leasing revenues in 1997 and the higher gross
margin on sales of units in 1997. Our effective tax rate was reduced to 40.0% in
1997 from 44.0% in 1996. Excluding the 1996 restructuring charge, earnings
before extraordinary item would have been $873,000, or $0.13 per diluted share
of common stock.


LIQUIDITY AND CAPITAL RESOURCES


Our leasing and manufacturing businesses are very capital intensive. We have
financed our working capital requirements through cash flows from operations,
proceeds from equity and debt financings and borrowings under our credit
facility.


Operating Activities. Our operations provided net cash flow of $8.5 million in
1998, $6.1 million in 1997 and $1.4 million in 1996. This increasing cash flow
resulted primarily from our higher net income, increased depreciation expense
and deferred income taxes. The growth of our business, however, required us to
use more cash to support higher levels of accounts receivable and inventory.


Investing Activities. Net cash used in investing activities was $31.2 million in
1998, $19.2 million in 1977 and $10.8 million in 1996. This increasing use of
cash resulted primarily from higher levels of capital expenditures for lease
fleet expansion and acquisitions. Capital expenditures for our lease fleet were
$23.5 million in 1998, $17.1 million in 1997 and $7.7 million in 1996. Capital
expenditures for property, plant and equipment were $3.8 million in 1998, $2.1
million in 1997 and $3.0 million in 1996. In addition, we spent $3.9 million in
1998 for acquisitions. No acquisitions were completed in 1996 or 1997.


-18-
20
Financing Activities. Net cash provided by financing activities was $22.8
million in 1998, $13.4 million in 1997 and $8.7 million in 1996. During 1998,
net cash provided by financing activities was primarily from $21.3 million of
net borrowings under our credit facility and $5.7 million of gross proceeds from
the exercise of warrants to purchase shares of our common stock. The majority of
warrants exercised were issued in connection with our initial public offering in
1994. During 1997, the net cash provided by financing activities was primarily
from $9.5 million of net borrowings under our credit facility and $6.9 million
of proceeds from the issuance of 12% Senior Subordinated Notes with detachable
redeemable warrants. During 1996, net cash provided by financing activities was
primarily from $22.3 million of net borrowings under our credit facility and
$7.1 million of proceeds from the issuance of notes.

The Company entered into an Interest Rate Swap Agreement (the Agreement)
effective in September 1998, under which the Company is designated as the fixed
rate payer at an interest rate of 5.5% per annum. Under the Agreement, the
Company has effectively fixed, for a three year period, the interest rate
payable on $30 million of its revolving line of credit so that the rate is based
upon a spread from 5.5%, rather than a spread from the Eurodollar rate.

Since March 1996, our principal source of liquidity has been our credit
facility, which consists of a $75 million revolving line of credit and a $6
million term loan. The interest rate under our credit facility is determined
quarterly, based on our ratio of funded debt to earnings before interest, taxes,
depreciation and amortization (EBITDA). During 1998, the average interest rate
under our credit facility was 7.7%. As of March 15, 1999, we had $59.3 million
of outstanding borrowings under our credit facility, and $10.7 million of
additional borrowings were available.

The amount we can borrow under the revolving line of credit portion of our
credit facility is based upon the level of our inventories, accounts receivable
and the value of our lease fleet. The lease fleet is appraised at least annually
for purposes of the credit facility. Our obligations under the credit facility
are secured by a lien on substantially all of our assets, including all of our
portable storage units.

The credit facility includes a term loan due in March 2002. The term loan had an
outstanding principal balance of $3.7 million at December 31, 1998. We must make
principal and interest payments monthly on the term loan.

In October 1997, we issued $6.9 million of 12% Senior Subordinated Notes with
detachable redeemable warrants to purchase 172,500 shares of our common stock at
$5.00 per share. These notes are due November 1, 2002 but may be prepaid after
November 1, 1999 without a prepayment penalty. We used the net proceeds from the
sale of these notes to repay $3.0 million in bridge notes issued in July 1997
and to reduce borrowings under our revolving line of credit. Because the notes
were sold with redeemable warrants, a portion of the sale price was allocated to
the notes and a portion to the redeemable warrants, based on their respective
fair market values. The resulting discount increases the effective interest rate
on the notes, and we are amortizing it as interest expense over the life of the
notes.

We believe that our working capital, together with our cash flow from
operations, borrowing under our credit facility and other available funding
sources will be sufficient to fund our operations and controlled growth for the
next 12 months. We believe that in order to maintain historical growth rates we
will be required to obtain additional debt financing and to raise additional
equity capital by issuing additional shares of our stock. However, we cannot
assure that we can obtain the necessary debt or equity financing on acceptable
terms.

SEASONALITY


Although demand from some of our customers is somewhat seasonal, our operations
as a whole has not been very seasonal. Demand for leases of our portable storage
units is stronger from September through December because retailers need to
store more inventory for the holiday season. Our retail customers usually return
leased units to us early in the following year. This has caused lower
utilization rates for our lease fleet and a marginal decrease in cash flow
during the first quarters of the past several years.


YEAR 2000 COMPLIANCE AND EXPENDITURES


We recognize the problems associated with Year 2000 transactions and have
evaluated our computer hardware and software systems for potential Year 2000
compliance issues relating to internal operating systems, suppliers and
customers and third party services that we rely on in our daily operations.


-19-
21
Internal Operating Systems. We have completed our assessment of our major
internal operating systems. We installed a new software system in 1997 which has
been certified by the vendor to be fully Year 2000 compliant. We continue to
test this software, and all our other software and hardware, for compliance. We
believe our major internal operating systems are Year 2000 compliant and we will
test any new modular software packages added to our primary operating system. We
expect our assessment of internal operating systems to be fully complete in the
second quarter of 1999. The Company presently believes that with modifications
to existing software, conversions to new software and replacement of some
hardware, the Year 2000 issue will be satisfactorily resolved in its own
internal operating systems by the third quarter of 1999. The Company has
established an internal auditing process to track and verify the results of its
plan and tests.


Suppliers and Customers. We are currently evaluating the Year 2000 readiness of
our material vendors and suppliers. We have forwarded questionnaires to all of
our major suppliers and will evaluate responses on a case-by-case basis. We are
placing the emphasis of this review on our primary vendors, such as steel, paint
and other suppliers and the phone systems. In the event that our suppliers are
not Year 2000 compliant in a timely manner, we could experience a shortage in
material supplies and, as a result, our business and results of operations could
be materially and adversely affected. We also sent questionnaires to our larger
leasing customers for the Year 2000 issue. If the majority of our corporate
customers are not Year 2000 compliant in a timely manner, customer lease
payments to us could be delayed and our cash flow would be affected. We have not
yet received sufficient information from suppliers and customers about their
Year 2000 compliance and remediation plans to predict the outcome of their
efforts.


Third Party Services. We have contacted our outside service providers, including
banks, invoice processors and payroll processors and discussed their assessment
of their Year 2000 readiness. We have been advised by the Agent under the credit
facility that the Year 2000 is not expected to cause delays or other problems in
connection with our transactions under that facility. We have not yet received
sufficient information from other third party servicers about their Year 2000
compliance and remediation plans to predict the outcome of their efforts. Where
we are dependent on third party service providers, if they are not Year 2000
compliant in a timely manner our operations could be disrupted and our business
and results of operations could be materially and adversely affected.


We are developing a contingency plan that is expected to address financial and
operational problems that might arise on and around January 1, 2000. This
contingency plan would include identifying back-up processes that do not rely on
computers whenever possible. We have incurred and expect to continue to incur
expenses allocable to internal staff, as well as costs for computer systems'
remediation and replacement in order to achieve Year 2000 compliance. We
currently estimate that these costs will total approximately $122,000. We have
incurred relatively low costs to date primarily due to the new software system
implemented in 1997 that is year 2000 compliant. The costs of the Year 2000
program and the date on which we plan to be completely Year 2000 compliant are
based on current estimates, which reflect numerous assumptions about future
events, including the continued availability of certain resources, the timing
and effectiveness of third-party remediation plans and other factors. There can
be no assurance that these estimates will be achieved, and actual results could
differ materially from our plans. Specific factors that might cause such
material differences include the availability and cost of personnel trained in
this area, the ability to locate and correct relevant computer source codes and
embedded technology, the results of internal and external testing and the
timelessness and the effectiveness of remediation efforts of third parties.


If the modifications and conversions referred to above are not made or are not
completed on a timely basis, the Year 2000 issue could have a material adverse
effect on our business and results of operations. Moreover, even if these
changes are successful, failure of third parties to which we are financially or
operationally linked to address their own system problems could have a material
adverse effect on us.


ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company seeks to reduce earnings and cash flow volatility associated with
changes in interest rates by entering into financial arrangements intended to
provide a hedge against a portion of the risks associated with such volatility.
The Company continues to have exposure to such risks to the extent they are not
hedged.

An interest rate swap agreement is the only instrument used by the Company to
manage interest rate fluctuations affecting the Company's variable rate debt.
The Company currently has one outstanding interest rate swap agreement under
which the Company pays a fixed rate and receives a variable interest rate. The
following table sets forth the scheduled maturities and the total fair value of
the Company's debt portfolio:



Total Fair
At December 31, Total at Value at
----------------------------------------------------------------- December 31, December 31,
1999 2000 2001 2002 2003 Thereafter 1998 1998
---- ---- ---- ---- ---- ---------- ------------ -----------

Liabilities
Fixed Rate (in 000's) $2,780 $1,058 $ 187 $ 6,923 $ 81 -- $11,029 $12,162
Average interest rate 11.8%
Floating rate (in 000's) $ 938 $1,188 $ 1,250 $57,496 $60,872 $60,872
Average interest rate 7.4%
Interest Rate Swaps
Variable to fixed (in 000's) $30,000 $30,000 $30,000
Average pay rate 5.5%
Average receive rate 1 mo LIBOR-BBA


The Company enters into derivative financial arrangements only to the extent
that it meets the objectives described above, and the Company does not engage in
such transactions for speculative purposes. The Company's credit facility
matures in 2002, including a one-year option. These variable rate liabilities
will continue to increase due to future growth until maturity.

See Note 3 -- Line of Credit in the notes to financial statements incorporated
herein by reference for further description of the variable rate liability.

Management intends to renew or replace the line of credit with similar
arrangements or debt prior to maturity, on terms as reasonably favorable to
their existing terms. The Company however, cannot be certain that such financing
will be available or on terms acceptable to the Company.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Mobile Mini, Inc.:

We have audited the accompanying consolidated balance sheets of MOBILE MINI,
INC. (a Delaware corporation) and subsidiaries as of December 31, 1997 and 1998,
and the related consolidated statements of operations, stockholders' equity and
cash flows for each of the three years in the period ended December 31, 1998.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Mobile Mini, Inc. and
subsidiaries as of December 31, 1997 and 1998 and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1998, in conformity with generally accepted accounting principles.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule listed in the index of the
financial statements is presented for the purpose of complying with the
Securities and Exchange Commission's rules and is not a required part of the
basic financial statements. This schedule has been subjected to the auditing
procedures applied in our audits of the basic financial statements and, in our
opinion, fairly states in all material respects the financial data required to
be set forth therein in relation to the basic financial statements taken as a
whole.

MOBILE MINI, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 1997 AND 1998


(1) THE COMPANY, ITS OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING
POLICIES:


Organization and Special Considerations


Mobile Mini, Inc., a Delaware corporation, is a leading provider of portable
storage leasing solutions. The Company designs and manufactures portable steel
storage units and acquires and refurbishes used ocean-going shipping containers
for lease primarily in Arizona, California, Texas, Nevada, Oklahoma, New Mexico
and Colorado. In addition to its leasing operations, the Company sells new and
used portable storage units and provides other ancillary services.

The Company has experienced rapid growth during the last several years with
lease revenues increasing at a 39.6% compounded rate during the last four years.
This growth is related to the expansion of the Company's portable storage unit
lease fleet at existing locations in Arizona, California, Texas and new
locations added in 1998 in Nevada, Oklahoma, New Mexico and Colorado.


The Company believes that its current capitalization, together with borrowings
available under the Credit Facility, is sufficient to permit controlled growth.
However, should demand for the Company's products continue to grow at a
significant rate, the Company will be required to secure additional financing
through additional borrowings, debt or equity offerings, or a combination of
these sources to meet this demand. The Company believes that such financing will
be available; however, there is no assurance that any such financings will be
available or on terms acceptable to the Company.


The Company's ability to obtain used containers for its lease fleet is subject
in large part to the availability of these containers in the market. This is in
part subject to international trade issues and the demand for containers in the
ocean cargo shipping business. Should there be a shortage in supply of used
containers, the Company could supplement its lease fleet with new portable
storage units manufactured by the Company. However, should there be an
overabundance of these used containers available, it is likely that prices would
fall. This could result in a reduction in the lease rates the Company could
obtain from its portable storage unit leasing operations. It could also cause
the appraised orderly liquidation value of the portable storage units in the
lease fleet to decline. In such event, the Company's ability to finance its
business through the Credit Facility would be affected as the maximum borrowing
limit under that facility is based upon the appraised orderly liquidation value
of the Company's portable storage unit lease fleet. In addition, under the
Credit Facility, the Company is required to comply with certain covenants and
restrictions as more fully discussed in Note 3. If the Company fails to comply
with these covenants and restrictions, the lender has the right to refuse to
lend the Company additional funds and may require early payment of amounts owed
to the lender. If this happens, it would materially impact the Company's growth
and ability to fund ongoing operations. Furthermore, because a substantial
portion of the amount borrowed under the Credit Facility bears interest at a
variable rate, a significant increase in interest rates could have a materially
adverse affect on the results of operations and financial condition of the
Company.

Principles of Consolidation


The consolidated financial statements include the accounts of Mobile Mini, Inc.
and its wholly owned subsidiary, Mobile Mini I, Inc. (collectively the
"Company"). All material intercompany transactions have been eliminated.


Revenue Recognition


The Company recognizes revenue from sales of containers upon delivery. Revenue
generated under portable storage unit leases is recognized as earned when the
customer is invoiced.


Revenue under certain contracts for the manufacture of telecommunication
shelters is recognized using the percentage-of-completion method primarily based
on contract costs incurred to date compared with total estimated contract costs.
Provision for estimated losses on uncompleted contracts are made in the period
in which such losses are determined. Costs and estimated earnings in excess of
billings on uncompleted contracts is approximately $307,000 and $73,000 at
December 31, 1997 and 1998 respectively, and are included in receivables in the
accompanying consolidated balance sheets.


Revenue from portable storage unit delivery and hauling is recognized as these
services are provided.

Concentrations of Credit Risk

Financial instruments which potentially expose the Company to concentrations of
credit risk, as defined by Statement of Financial Accounting Standards (SFAS)
No. 105, consist primarily of receivables. Concentration of credit risk with
respect to receivables are limited due to the large number of customers spread
over a large geographic area in many industry segments. The Company's
receivables related to its sales operations are generally secured by the product
sold to the customer. The Company's receivables related to its leasing
operations are primarily small month-to-month amounts generated from both off
site and on site customers. The Company has the right to repossess the portable
storage unit, including any customer goods, for non payment.


The Company's leasing customers by major category are presented below:



1997 1998

Cash and Cash Equivalents


Cash and cash equivalents at December 31, 1997 and 1998 include $416,800 and
$415,800, respectively, (including earned interest) in an interest reserve
account as required under the Indenture (see Note 6) in connection with the
Company's 12% Senior Subordinated Notes and represent an amount equal to at
least six months interest based on the principal amount outstanding.


Inventories


Inventories are stated at the lower of cost or market, with cost being
determined under the specific identification method. Market is the lower of
replacement cost or net realizable value. Inventories at December 31 consist of
the following:

Property, Plant and Equipment


Property, plant and equipment are stated at cost, net of accumulated
depreciation. Depreciation is provided using the straight-line method over the
assets' estimated useful lives. Salvage values are determined when the property
is constructed or acquired and range up to 25%, depending on the nature of the
asset. In the opinion of management, estimated salvage values do not cause
carrying values to exceed net realizable value. Normal repairs and maintenance
to property, plant and equipment are expensed as incurred.


Property, plant and equipment at December 31 consist of the following:

approximately $107,000 and $165,000, at December 31, 1997 and 1998,
respectively.


At December 31, 1997 and 1998, a portion of property, plant and equipment was
pledged as collateral for notes payable obligations and obligations under
capital leases (see Notes 3, 4 and 5).


Accrued Liabilities


Included in accrued liabilities in the accompanying consolidated balance sheets
are customer deposits and prepayments totaling approximately $485,000 and
$645,000 for the years ended December 31, 1997 and 1998, respectively.


Earnings Per Share


The Company has adopted SFAS No. 128, Earnings per Share. Pursuant to SFAS No.
128, basic earnings per common share are computed by dividing net income by the
weighted average number of shares of common stock outstanding during the year.
Diluted earnings per common share are determined assuming that options were
exercised at the beginning of each year or at the time of issuance. SFAS No. 128
is effective for financial statements for both interim and annual periods
presented after December 15, 1997 and as a result, all prior period earnings per
share (EPS) data presented has been restated.

Long-Lived Assets


The Company periodically evaluates the carrying value of long-lived assets in
accordance with SFAS No. 121 Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to be Disposed of. Under SFAS No. 121, long-lived
assets and certain identifiable intangible assets to be held and used in
operations are reviewed for impairment whenever events or circumstances indicate
that the carrying amount of an asset may not be fully recoverable. An impairment
loss is recognized if the sum of the expected long-term undiscounted cash flows
is less than the carrying amount of the long-lived assets being evaluated.


Fair Value of Financial Instruments


The estimated fair value of financial instruments has been determined by the
Company using available market information and valuation methodologies.
Considerable judgment is required in estimating fair values. Accordingly, the
estimates may not be indicative of the amounts the Company could realize in a
current market exchange.


The carrying amounts of cash and cash equivalents, receivables and accounts
payable approximate fair values. The carrying amounts of the Company's
borrowings under the revolving line of credit and certain variable rate notes
payable instruments approximate fair value. The fair value of the Company's
variable rate notes payable and revolving line of credit is estimated using
discounted cash flow analyses, based on the Company's current incremental
borrowing rates for similar types of borrowing arrangements. Based on the
borrowing rates currently available to the Company for bank loans with similar
terms and average maturities, the fair value of fixed rate long-term debt at
December 31, 1998 is approximately $12,100,000.


Deferred Financing Costs


Included in other assets are deferred financing costs of approximately
$2,104,000 and $2,032,000 at December 31, 1997 and 1998, respectively. These
costs of obtaining long-term financing are being amortized over the term of the
related debt, using the straight-line method. The difference between amortizing
the deferred financing costs using the straight-line method and amortizing such
costs using the effective interest method is not material.


F-10
32
Use of Estimates


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 disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenue and expenses during the reporting period. Actual
results could differ from those estimates.


Reclassifications


Certain prior period amounts in the accompanying financial statements have been
reclassified to conform to the current year presentation.


Impact of Recently Issued Accounting Standards


In June 1998, SFAS No. 133, Accounting for Derivative Instruments and Hedging
Activities, was issued. This statement establishes accounting and reporting
standards requiring that every derivative instrument (including certain
derivative instruments embedded in other contracts) be recorded in the balance
sheet as either an asset or liability measured at its fair value. The statement
requires that changes in the fair value of the derivative be recognized
currently in earnings unless specific hedge accounting criteria are met. If
specific hedge accounting criteria are met, changes in the fair value of
derivatives will either be offset against the change in the fair value of the
hedged assets, liabilities, or firm commitments through earnings, or recognized
in other comprehensive income until the hedged item is recognized in earnings.
The ineffective portion of a derivative's change in fair value will be
immediately recognized in earnings. SFAS No. 133 is effective for fiscal years
beginning after June 15, 1999. The Company expects to adopt SFAS No. 133
effective January 1, 2000. Management believes the impact of adopting SFAS No.
133 will not have any material impact on the Company's financial statements.


(2) PORTABLE STORAGE UNIT LEASE FLEET:


The Company has a portable storage unit lease fleet consisting of refurbished or
manufactured containers that are leased to customers under short-term operating
lease agreements with varying terms. Depreciation is provided using the
straight-line method over the portable storage units estimated useful lives of
20 years with salvage values estimated at 70% of cost. In the opinion of
management, estimated salvage values do not cause carrying values to exceed net
realizable value. Portable storage units included in the lease fleet with an
original loan value of approximately $9.2 million at December 31, 1997 and $7.0
million at December 31, 1998, have been pledged as collateral for notes payable
and obligations under capital leases. The balance of the portable storage units
are pledged as collateral under the Credit Facility (see Notes 3, 4 and 5).
Normal repairs and maintenance to the portable storage units are expensed as
incurred.


Portable storage unit lease fleet includes assets acquired under capital leases
of approximately $8,255,000 and $6,435,000, and accumulated depreciation of
approximately $317,000 and $361,000 at December 31, 1997 and 1998, respectively.


(3) LINE OF CREDIT:


In March 1996, the Company entered into the Credit Facility. Under the terms of
the Credit Facility, as amended, the Lenders have provided the Company with a
$75.0 million revolving line of credit and a term loan. Borrowings under the
Credit Facility are secured by substantially all of the Company's assets.


Available borrowings under the revolving line of credit are based upon the level
of the Company's inventories, receivables and portable storage unit lease fleet.
The portable storage unit lease fleet is appraised at least annually, and up to
90% of the lesser of cost or appraised orderly liquidation value, as defined,
may be included in the borrowing base. The interest rate on the revolving line
of credit is fixed quarterly based on the Company's ratio of funded debt to
earnings before interest, taxes, depreciation and amortization. Borrowings, are
at the Company's option, at either the prime or the Eurodollar rate, and
interest accrues at a certain spread relative to


F-11
33
the Company's debt ratio in effect. At December 31, 1998, the prime rate was
7.75% and the Eurodollar rate ranged from 5.31% to 5.56%. The interest rate
charged under the revolving line of credit at December 31, 1998 was 8.25% for
prime rate borrowings and ranged from 7.31% to 7.56% for Eurodollar borrowings.
For the first quarter of 1999, the interest rate decreased by 0.25% as a result
of the Company's funded debt ratio at December 31, 1998. The revolving line of
credit expires in March 2002, including a one-year extension option.


In connection with the closing of the Credit Facility, the Company terminated
its line of credit with its previous lender, repaying all indebtedness under
that line. In addition, the Company repaid other long-term debt and obligations
under capital leases totaling $14.1 million. As a result, the Company recognized
costs previously deferred related to certain indebtedness and prepayment
penalties, which resulted in an extraordinary charge to earnings in 1996 of
$410,000 after benefit for income taxes.


The revolving line of credit balance outstanding was approximately $35.9 million
and $57.2 million at December 31, 1997 and 1998, respectively. The amount
available for borrowing was approximately $9.4 million at December 31, 1998.
During 1997 and 1998, the weighted average interest rate under the line of
credit was 8.93% and 7.67%, respectively, and the average balance outstanding
during 1997 and 1998 was approximately $32.2 million and $45.1 million,
respectively.


The Company entered into an Interest Rate Swap Agreement (the Agreement)
effective in September 1998, under which the Company is designated as the fixed
rate payer at an interest rate of 5.5% per annum. Under the Agreement, the
Company has effectively fixed, for a three year period, the interest rate
payable on $30 million of its revolving line of credit so that it is based upon
a spread from 5.5%, rather than a spread from the Eurodollar rate. The Company
accounts for this agreement as a hedge of an existing liability in conformance
with SFAS No. 80, Accounting for Futures Contracts. Interest expense is accrued
using the fixed rate identified in the Agreement. The Company's objective in
entering into this transaction was to reduce the risk of interest rate
fluctuations in the future. As the Company intends to continue to operate with
leverage, management believed it was prudent to lock in a fixed interest rate at
a time when fixed rates had significantly decreased.


The Credit Facility contains several covenants including a minimum consolidated
tangible net worth requirement, a minimum fixed charge coverage ratio, a maximum
ratio of debt to equity, minimum operating income levels and minimum required
utilization rates. In addition, the Credit Facility contains limits on capital
expenditures and the incurrence of additional debt, as well as prohibiting the
payment of cash dividends.


Additional principal payments equal to 75% of "Excess Cash Flow", as defined in
the term loan documents which constitute part of the Credit Facility, are
required annually. As of December 31, 1998, no additional payment was required
under this provision.

(5) OBLIGATIONS UNDER CAPITAL LEASES:


The Company has leased certain portable storage units, portable classroom
buildings and equipment under capital leases expiring through 2003 under
sale-leaseback arrangements with various leasing companies. The lease agreements
provide the Company with a purchase option at the end of the lease term based on
an agreed upon percentage of the original cost of the portable storage units.
These leases have been capitalized using interest rates ranging from
approximately 6% to 14%. The leases are secured by the portable storage units
and equipment under lease.


In 1994 and 1995, the Company entered into multi-year agreements (the Leases) to
lease a number of portable classrooms to school districts in Arizona. Subsequent
to entering the leases, the Company sold the portable classrooms and assigned
the Leases to an unrelated third party. For financial reporting purposes these
transactions were not recorded as sales but accounted for as collateralized
borrowings in accordance with SFAS No. 13. For income tax purposes these
transactions were treated as sales.


F-13
35
During 1996, leases on 15 of the portable classroom buildings matured, and the
Company sold all 15 buildings. During 1998, the Company negotiated the sale of
all remaining portable classrooms under lease. The revenues from these sales are
included in the accompanying statements of operations, and the underlying
capital lease obligations for these buildings were paid in full.


Future payments of obligations under capital leases:



Years ending December 31,

1999 $2,460,122
2000 819,733

2003 84,920
----------
Total payments 3,500,865
Less: Amounts representing interest (304,844)
----------

==========



Certain obligations under capital leases contain financial covenants, which
require the Company to maintain a specified minimum tangible net worth, a
maximum funded indebtedness and a maximum senior funded indebtedness ratio.


Gains from sale-leaseback transactions have been deferred and are being
amortized over the estimated useful lives of the related assets. Unamortized
gains at December 31, 1997 and 1998, approximated $271,000 and $254,000,
respectively, and are reflected as a reduction in the portable storage unit
lease fleet in the accompanying consolidated financial statements.


(6) 12% SENIOR SUBORDINATED NOTES:


In October 1997, the Company issued $6.9 million of 12% Senior Subordinated
Notes (the Notes) with a scheduled maturity date of November 1, 2002 and which
are unsecured obligations of the Company. The Company may redeem the notes at
par on or after November 1, 1999. The Notes were issued as part of a unit with
Redeemable Warrants to purchase 172,500 shares of the Company's common stock at
$5.00 per share. Additionally, the Company issued warrants to purchase 15,000
shares of common stock to the underwriters. The Company is required to maintain
an interest reserve account and to maintain in the reserve account, while any of
the Notes are outstanding, an amount equal to six months interest on the Notes
based on the principal amount outstanding. As of December 31, 1998 and 1997, the
outstanding balance of the Notes was $6.7 million and $6.6 million, net of the
remaining unamortized discount of approximately $200,000 and $300,000,
respectively. Interest is payable on May 1 and November 1 of each year,
commencing May 1, 1998. Because the Notes were offered as part of a unit with
Redeemable Warrants, a portion of the original offering price for a unit was
allocated to the Notes and a portion to the Redeemable Warrants based on their
respective fair market values. The resulting discount increases the effective
interest rate of the Notes and is being amortized to interest expense over the
life of the Notes. The Indenture governing the Notes requires the Company to
comply with certain covenants including maintaining a specific tangible net
worth, a maximum total funded indebtedness ratio and a maximum senior funded
indebtedness ratio.

In July 1997, the Company completed a private placement of $3.0 million of 12%
senior subordinated notes (the Bridge Notes) and warrants to purchase 50,000
shares of the Company's common stock at $5.00 per share. The Company used a
portion of the proceeds from the sale of the Notes described above to repay the
Bridge Notes in October of 1997. The Bridge Note lender received 15,000 shares
of common stock as consideration for the cancellation of the warrants
originally issued to the Bridge Note lender.

(7) INCOME TAXES:


The Company accounts for income taxes in accordance with SFAS No. 109,
Accounting for Income Taxes. SFAS No. 109 requires the use of an asset and
liability approach in accounting for income taxes. Deferred tax assets and
liabilities are recorded based on the differences between the financial
statement and tax bases of assets and liabilities at the tax rates in effect
when these differences are expected to reverse.


F-14

A reconciliation of the federal statutory rate to the Company's effective tax
rate for the years ended December 31 are as follows:

At December 31, 1998, the Company had a federal net operating loss carryover of
approximately $20,759,000 and a state net operating loss carryover of
approximately $11,640,000 which expire if unused in years 2008 to 2018 and 1999
to 2003, respectively.


As a result of stock ownership changes during the years presented, it is
possible that the Company has undergone one or more changes in ownership which
can limit the amount of net operating loss currently available as a deduction.
Such limitation could result in the Company being required to pay tax currently
because only a portion of the net operating loss is available. Management
believes that it will fully realize its net operating loss carryforward and that
a valuation reserve was not necessary at December 31, 1998.


(8) TRANSACTIONS WITH RELATED PARTIES:


The Company leases a portion of the property comprising its Phoenix location and
the property comprising its Tucson location from Richard E. Bunger's five
children. Mr. Bunger is an executive officer, director and founder of the
Company. Annual base payments under these leases total approximately $66,000
with an annual adjustment based on the Consumer Price Index. The term of each of
these leases will expire on December 31, 2003. Additionally, the Company leases
its Rialto, California facility from Mobile Mini Systems, Inc., a corporation,
wholly owned by Mr. Bunger, for total annual base payments of $204,000, with
annual adjustments based on the Consumer Price Index. The Rialto lease is for a
term of 15 years, expiring on December 31, 2011. Management believes the rental
rates reflect the fair market value of these properties. The Company purchased
certain leased property at its Maricopa, Arizona facility from Mr. Bunger on
March 29, 1996, for a purchase price of $335,000, which management believes
represented the fair market value of the property.


F-15
37
The Company obtains services throughout the year from Skilquest, Inc., a company
engaged in sales and management support programs. Skilquest, Inc. is owned by
Carolyn Clawson, the daughter of Mr. Richard E. Bunger and sister of Steven G.
Bunger. The Company made aggregate payments of approximately $73,000 and $69,000
to Skilquest, Inc. in 1997 and 1998 respectively, which the Company believes
represented the fair market value for the services performed.


The Company acquired 20 trucks from Richard E. Bunger in October, 1998. The
purchase price was $256,000 which the Company believes represented the fair
market value for these assets.


All ongoing and future transactions with affiliates will be on terms no less
favorable than could be obtained from unaffiliated parties and will be approved
by a majority of the independent and disinterested directors.


(9) BENEFIT PLANS:


STOCK OPTION PLAN


In August 1994, the Company's board of directors adopted the Mobile Mini, Inc.
1994 Stock Option Plan ("the Plan"). Under the terms of the Plan, both incentive
stock options ("ISOs"), which are intended to meet the requirements of Section
422 of the Internal Revenue Code, and non-qualified stock options may be
granted. ISOs may be granted to the officers and key personnel of the Company.
Non-qualified stock options may be granted to the Company's directors and key
personnel, and to providers of various services to the Company. The purpose of
the Plan is to provide a means of performance-based compensation in order to
attract and retain qualified personnel and to provide an incentive to others
whose job performance or services affect the Company.


Under the Plan, as amended in 1998, options to purchase a maximum of 1,200,000
shares of the Company's common stock may be granted. The exercise price for any
option granted under the Plan may not be less than 100% (110% if the option is
an ISO granted to a stockholder who at the time the option is granted owns stock
comprising more than 10% of the total combined voting power of all classes of
stock of the Company) of the fair market value of the common stock at the time
the option is granted. The option holder may pay the exercise price in cash or
by delivery of previously acquired shares of common stock of the Company that
have been held for at least six months.


The Plan is administered by the compensation committee of the board of
directors, which determines whether options will be granted, whether options
will be ISOs or non-qualified options, which directors, officers, key personnel
and service providers will be granted options, the vesting schedule for options
and the number of options to be granted, subject to the aggregate maximum number
set forth above. Each option granted must expire no more than 10 years from the
date it is granted.


The board of directors may amend the Plan at any time, except that approval of
the Company's shareholders is required for any amendment that increases the
aggregate number of shares which may be issued pursuant to the Plan, changes the
class of persons eligible to receive options, modifies the period within which
options may be granted, modifies the period within which options may be
exercised or the terms upon which options may be exercised, or increases the
material benefits accruing to the participants under the Plan. Unless previously
terminated by the board of directors, the Plan will terminate in November, 2003,
but any option granted thereunder will continue until its expiration date.


The Company accounts for its stock-based compensation plan under APB No. 25,
under which no compensation expense has been recognized in the accompanying
financial statements for stock-based employee awards. All stock options have
been granted with an exercise price equal to or greater than the fair value of
the Company's common stock on the date of grant. The Company adopted SFAS No.
123 for disclosure purposes in 1996. For purposes of SFAS No. 123, the fair
value of each option granted has been estimated at the date of the grant using
the Black-Scholes option pricing model using the following assumptions:


F-16
38


1996 1997 1998
---- ---- ----

Risk free interest rates range 6.4% 6.0 to 6.6% 5.27 to 5.49%
Expected holding period 4.0 years 4.0 years 4.0 years
Dividend rate 0.0% 0.0% 0.0%
Expected volatility 48.0% 55.4% 53.5%



Under these assumptions, the fair value of the stock options granted was
$99,418, $190,570 and $329,774 for 1996, 1997 and 1998, respectively. These
amounts would be amortized on the straight-line basis as compensation expense,
over the average holding period of the options. If the Company had accounted for
stock options consistent with SFAS No. 123, utilizing the assumptions detailed
above, the Company's net income and earnings per share would have been reported
as follows at December 31:



1996 1997 1998
---------- ------------- -------------

Net income
As reported $ 70,222 $ 2,200,396 $ 4,483,967
Pro forma 14,548 2,086,054 4,286,102
Basic EPS:
As reported $ 0.01 $ 0.33 $ 0.57
Pro forma -- 0.31 0.55
Diluted EPS:
As reported $ 0.01 $ 0.32 $ 0.53
Pro forma -- 0.31 0.51



The effect of applying SFAS No. 123 for providing pro forma disclosures is not
likely to be representative of the effect on reported net income or earnings per
share for future years, because options vest over several years, additional
stock options are generally awarded in each year, and SFAS No. 123 has not been
applied to options granted prior to January 1, 1995.


The following summarizes the activities under the Company's stock option plan
for the years ended December 31, 1996, 1997 and 1998:

401(k) PLAN


In 1995, the Company established a contributory retirement plan (the 401(k)
Plan) covering eligible employees with at least one year of service. The 401(k)
Plan is designed to provide tax-deferred retirement benefits to the Company's
employees in accordance with the provisions of Section 401(k) of the Internal
Revenue Code.


The 401(k) Plan provides that each participant may annually contribute 2% to 15%
of his or her salary, not to exceed the statutory limit. The Company may make a
qualified non-elective contribution in an amount as determined by the Company.
Under the terms of the 401(k) Plan, the Company may also make discretionary
profit sharing contributions. Profit sharing contributions are allocated among
participants based on their annual compensation. Each participant has the right
to direct the investment of their funds among certain named plans. The Company
did not make any qualified non-elective contributions or profit sharing
contributions to the 401(k) Plan prior to 1997. In 1997 and 1998, the Company
contributed 10% of the employees contributions up to a maximum of $500 per
employee.


(10) COMMITMENTS AND CONTINGENCIES:


As discussed more fully in Note 8, the Company is obligated under noncancellable
operating leases with related parties. The Company also leases its corporate
offices and other properties, as well as operating equipment from third parties
under noncancellable operating leases. Rent expense under these agreements was
approximately $649,000, $932,000, and $1,413,000 for the years ended December
31, 1996, 1997, and 1998, respectively. Total future commitments under all
noncancellable agreements for the years ended December 31, are approximately as
follows:




1999 $1,437,000
2000 1,435,000
2001 1,172,000
2002 895,000
2003 690,000
Thereafter 3,707,000
----------
$9,336,000
==========



The Company is involved in certain legal proceedings arising in the normal
course of business. In the opinion of management, the Company's potential
exposure under the pending proceedings is adequately provided for in the
accompanying financial statements and any adverse outcome will not have a
material impact on the Company's results of operations or its financial
condition.

(11) STOCKHOLDERS' EQUITY:


REDEEMABLE WARRANTS


Redeemable Warrants to purchase 187,500 shares of the Company's common stock at
$5.00 per share (subject to adjustment as described below) were issued in
connection with the issuance of the Notes (Note 6). A portion of the original
offering price was allocated to the Notes and the Redeemable Warrants based on
their relative fair values. The Redeemable Warrants first became exercisable on
March 1, 1998. The expiration date of the Redeemable Warrants is November 1,
2002. After October 13, 1999, the Company has the right to redeem the Redeemable
Warrants at any time after the date that the closing price of the common stock
has equaled or exceeded $8.75 per share for a period of 20 consecutive trading
days. The redemption price is $0.05 per Redeemable Warrant.


The number of shares of common stock for which a Redeemable Warrant is
exercisable and the purchase price thereof are subject to adjustment from time
to time upon the occurrence of certain events, including certain dividends and
distributions and issuances of shares of common stock at a price below the
market price. A Redeemable Warrant does not entitle the holder thereof to
receive any dividends paid on common stock nor does a holder of Redeemable
Warrants, as such, have any rights of a stockholder of the Company. As of
December 31, 1998, 4,875 of the Redeemable Warrants had been exercised for an
equal amount of the Company's common stock, with proceeds to the Company of
approximately $24,000.


(12) ACQUISITIONS


The Company acquired the assets of three companies during the year ended
December 31, 1998. The acquisitions were accounted for as purchases in
accordance with Accounting Principals Boards (APB) Opinion No. 16, and
accordingly, the purchased assets were recorded at their estimated fair values
at the date of acquisition. The accompanying consolidated financial statements
include the operations of the acquired companies from their respective dates of
acquisition.


The aggregate purchase price of the operations acquired consist of:




Cash $3,944,000
Common Stock 684,000
Other acquisition costs 73,000
----------
Total $4,701,000
==========



The Company issued 18,022 shares of its common stock in 1998 and 85,468 shares
in 1999 in connection with these acquisitions.


The fair value of the assets purchased has been allocated as follows:




Receivables $ 42,000
Portable storage units 3,157,000
Equipment 179,000
Deposit and prepaid expenses 77,000
Goodwill 1,246,000
----------
Total $4,701,000
==========



Goodwill is amortized using the straight line method over 25 years from the date
of the acquisition. The Company did not make any acquisitions in 1997. Included
in other assets at December 31, 1998 is $1,210,000 of goodwill, net of
accumulated amortization of $36,000.


F-19

(13) SEGMENT REPORTING:


The Company has adopted SFAS No. 131, Disclosures about Segments of an
Enterprise and Related Information, effective December 31, 1998. SFAS No. 131
superseded SFAS No. 14, Financial Reporting for Segments of a Business
Enterprise. Pursuant to SFAS No. 131, public business enterprises must report
certain information about operating segments in annual financial statements of
the enterprise and in condensed financial statements of interim periods issued
to shareholders. The adoption of SFAS No. 131 did not affect results of
operations or financial position, but did affect the disclosure of segment
information.

The Company's management approach includes those segments within its enterprise
on which operating decisions are made based on evaluation of performance,
results and profitability. The Company has two reportable segments: branch
operations and corporate sales. The branch operations segment includes the
leasing and sales of portable storage units to businesses and consumers in the
general geographic area of each branch. This segment also includes the Company's
dealer program and the manufacturing facilities which are responsible for the
purchase, manufacturing and refurbishment of the Company's products for leasing,
sales or equipment additions to the Company's delivery systems. The corporate
sales segment relates to the Company's specialty type product sales and includes
the Telecommunication and Modular divisions of the Company.


The accounting policies of the segments are the same as those described in Note
1. The Company evaluates performance and profitability before interest costs,
income taxes and major non-recurring transactions. The Company does not account
for intersegment revenues or expenses between its segments or divisions.


The Company's reportable segments concentrate on the Company's core business of
leasing, manufacturing, and selling of portable storage and office units.
Included in the branch operations segment is the Company's dealer division that
sells to the Company's dealer network, portable storage units which are
reasonably consistent with the storage units leased and sold by the Company's
branches. This business was discontinued in December 1998. The corporate sales
segment, which does not engage in leasing activities, is distinct in that its
products are highly customized designs and structures to accommodate specific
orders. Each operating segment has managers who meet regularly and are
accountable to the chief operating decision maker for operating activities,
financial results and ongoing plans including the influence of competition.

(1) Potential realizable value is based on the assumption that our common stock
appreciates at the annual rate shown, compounded annually, from the date of
grant until the expiration of the 10 year term. These numbers are calculated
based on Securities and Exchange Commission requirements and do not reflect
our projection or estimate of future stock price growth. Potential
realizable values are computed by: (i) multiplying the number of shares
subject to a given option by the exercise price, (ii) assuming that the
aggregate stock value derived from that calculation compounds as the annual
5% or 10% rate shown in the table for the entire 10-year term of the option,
and (iii) subtracting from that result the aggregated option exercise price.

G. Bunger, Lawrence Trachtenberg, Burton K. Kennedy Jr., and Russell Lemley.
Each of the agreements contained a covenant not to compete for a period of two
years after termination of employment and a covenant not to disclose
confidential information of a proprietary nature to third parties.


We had numerous bonus and incentive arrangements with several employees during
1998, including Mr. Richard E. Bunger, Mr. Steven G. Bunger, Mr. Trachtenberg,
Mr. Kennedy and Mr. Lemley. These agreements included an incentive program to
provide financial awards for increases in profitability, revenues and for the
attainment of quotas. The compensation agreements with Mr. Richard E. Bunger,
Mr. Steven G. Bunger and Mr. Trachtenberg were evaluated by an independent
executive compensation consulting organization and employees were compensated
based on commensurate fair market salaries plus the incentive program.


COMPENSATION OF DIRECTORS


We pay our directors (other than directors who are also officers) for their
service. Each director was paid $500 per board meeting in 1998 and will be paid
$15,000 per year plus $500 per board meeting in 1999. We also grant each outside
director an option to purchase 7,500 shares of common stock on each August 1.
The exercise price is equal to the fair market value of the common stock on the
grant date.

Section 16(a) of the Securities Exchange Act of 1934, as amended requires our
officers and directors, and persons who beneficially own more than ten percent
of our common stock, to file reports of ownership and change in ownership with
the Securities and Exchange Commission (the "SEC") and the Nasdaq Stock Market.
Such reports are filed on Form 3, Form 4, and Form 5 under the Exchange Act.
Officers, directors and greater than ten-percent shareholders are required by
Exchange Act regulations to furnish us with copies of all Section 16(a) forms
they file.


Based solely on its review of the copies of such forms received by it, or
written representations from certain reporting persons that no Forms 5 were
required for those persons, the Company believes that, during fiscal year ended
December 31, 1998, all officers, directors, and greater than ten-percent
beneficial owners complied with the applicable Section 16(a) filing
requirements.


ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT.


The following information as of March 29, 1999 concerning the beneficial
ownership of our common stock by each stockholder we know to beneficially own
more than five percent of our outstanding common stock, by each director, each
executive officer, and all executive officers and directors as a group.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.


We lease certain of our business locations from affiliates of Richard E. Bunger,
including his children. Mr. Bunger is an executive officer, director. We entered
into an agreement, effective January 1, 1994, to lease a portion of the property
comprising our Phoenix location and the property comprising our Tucson location
from Richard E. Bunger's five children. Total annual base lease payments under
these leases currently equal $66,000, with annual adjustment based on the
consumer price index. Lease payments in 1998 were approximately $73,000. The
term of each of these leases will expire on December 31, 2003. Prior to 1994,
these properties were leased by our predecessor at annual rental payments
equaling $14,000. We also entered into an agreement effective January 1, 1994 to
lease our Rialto facility from Mobile Mini Systems, Inc. for total annual base
lease payments of $204,000 with annual adjustments based on the consumer price
index. This lease agreement was extended for an additional five years during
1996. Lease payments in fiscal year 1998 equaled approximately $225,500. Prior
to 1994, the Rialto site was leased to our predecessor at an annual rate of
$132,000. Management believes the increase in rental rates reflect the fair
market rental value of these properties. Prior to the effectiveness of the
written leases, the terms were approved by our independent and disinterested
directors.


In March 1994 our manufacturing facility in Maricopa, Arizona needed additional
acreage to expand its manufacturing capabilities and began using approximately
22 acres of property owned by Richard E. Bunger. We leased this property from
Mr. Bunger with annual payments of $40,000 with an annual adjustment based on
the Consumer Price Index. We purchased the property from Mr. Bunger on March 29,
1996 for a purchase price of $335,000, which management believes reflected the
fair market value of the property.


We obtain services throughout the year from Skilquest, Inc., a sales and
management support company. Skilquest, Inc. is owned by Carolyn Clawson, the
daughter of Mr. Richard E. Bunger and sister to Steven G. Bunger. We paid
Skilquest, Inc. $69,000 in 1998, which we believe is the fair market value for
the services performed.


In October 1998, we bought 20 trucks from Richard E. Bunger for $256,000, which
we believe represented the fair market value of the trucks.
