5 SUMMARY The following summary highlights selected information from this prospectus and may not include all of the information that is important to you. To more fully understand our business and this offering, you should read the entire prospectus carefully, including the risk factors and our financial statements and related notes which begin on page F-1. MOBILE MINI, INC. OUR BUSINESS We believe we are the nation's largest provider of portable storage solutions through our lease fleet of over 26,000 portable storage units. We currently operate 13 branches located in seven southwestern and western states. Our portable storage products offer secure, temporary storage with immediate access. We have a diversified customer base of over 28,000 retailers, small and large businesses, construction companies, schools, governmental entities and homeowners. Our customers use our products for a wide variety of applications, including the storage of retail and manufacturing inventory, construction materials and equipment, documents and records and household goods. 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 customized features such as our patented security system, multiple doors, electrical wiring and shelving. We believe we offer superior, differentiated products and the broadest range of portable storage products in the industry. OUR MARKET OPPORTUNITY The portable storage industry is evolving and is currently highly fragmented with no national service provider. We believe this industry will continue to expand as the advantages of portable storage become more widely known. Portable storage brings the storage solution to the customer's location and addresses the need for secure, temporary storage with immediate access. Our portable storage products are primarily used by businesses rather than consumers. We believe that there are many markets in the United States where demand for portable storage products is underdeveloped and underserved. Many existing industry participants provide portable storage through unimproved ocean-going shipping containers or old over-the-road trailers. We believe our superior products and our professional, service-oriented approach allow us to both capture market share and expand market awareness of portable storage solutions when we enter a new market. Our goal is to become the leading national provider of portable storage. OUR LEASING FOCUS In 1996, we initiated a strategy of focusing on leasing instead of selling our portable storage units. Since then, we have increased our lease fleet by 14,600 units, or approximately 128%. We initiated this strategic shift because we believe leasing allows us to achieve strong growth, improved profitability and increased predictability of our business. We believe our leasing model is highly attractive because portable storage units: - Provide predictable, recurring revenues from leases with an average duration of 20 months - Have average monthly rental rates which recoup our unit investment in 26 months - Have useful lives exceeding 20 years, low maintenance and high residual values - Produce incremental leasing operating margins above 60% As a result of shifting our focus to leasing, we have achieved substantial increases in both revenues and profitability. In the past three years, our leasing revenues have increased from $15.5 million to $36.5 million, and we have achieved internal growth exceeding 30% compounded annually. 3

6 . Over the same period, we have increased our operating income from $4.6 million to $13.3 million and improved our operating margin from 11.4% to 25.3%. We believe that our competitive strengths and growth strategy, as outlined below, will help us achieve our goal of becoming the leading national provider of portable storage. OUR COMPETITIVE STRENGTHS Market Leadership. We are the largest provider of portable storage solutions in most of our markets. We believe we are creating brand awareness and that "Mobile Mini" is associated with high quality portable storage products and superior customer service. Superior, Differentiated Products. We offer the industry's broadest range of portable storage products with many customized features which differentiate our products from those of our competition. Customer Service Focus. We believe the portable storage industry is highly service intensive and essentially local. Our entire organization is focused on providing high levels of customer service and our salespeople work out of our branch locations to better understand local market needs. Diverse Customer Base. We have more than 28,000 customers across a wide range of industries. We believe this diversity reduces our susceptibility to economic downturns in our markets or in any of the industries in which our customers operate. Our diverse customer base also demonstrates the broad applications for our products and our opportunity to create future demand through target marketing. Customized Management Information Systems. We have recently made substantial investments in our management information systems to optimize fleet utilization, capture detailed customer data, improve financial performance and support our growth. Flexibility Afforded by Manufacturing. Our manufacturing capability allows us to offer a wide range of products and features and to develop new product applications. It also provides us with an additional supply of units in addition to ocean shipping containers. OUR GROWTH STRATEGY Focus on Core Portable Storage Leasing Business. We will continue to focus on growing our core leasing business and lease fleet as they produce predictable, recurring revenues and high operating margins. Increase Penetration of Existing Markets. We have been able to generate strong internal growth from our existing markets through aggressive marketing and lease fleet growth. We believe that by increasing awareness of the benefits of portable storage, we can continue to increase leasing revenues in our existing markets. Accelerate Branch Expansion. We believe our branch model can be introduced to many more markets throughout the United States. In 1998, we opened four new branches, three of which were through acquisitions. We intend to accelerate our branch openings to capitalize on our market opportunity. Develop New Products. We have historically been able to introduce new products and features that expand the applications and overall market for our storage products. Recent examples include our 10-foot wide unit, which provides 40% more usable storage space than a standard eight-foot wide unit, and our new records storage unit, which provides an accessible alternative to traditional document storage facilities. ------------------------ Our principal executive offices are located at 1834 West Third Street, Tempe, Arizona 85281, and our telephone number is (480) 894-6311. 4

7 RECENT DEVELOPMENTS National Security Containers, L.L.C. Acquisition. On April 3, 1999, we entered into an agreement to acquire substantially all of the assets of National Security Containers, L.L.C., a portable storage leasing company, for total consideration of $25.5 million. The closing of this acquisition is subject to a number of conditions but is expected to close before the end of April 1999. At the closing of this acquisition, we will pay $17.5 million in cash and issue shares of our redeemable Series B convertible preferred stock valued at $8 million. However, if this offering is completed prior to the closing of the acquisition, we will pay a total of $25.5 million in cash and will not issue the preferred stock. Closing of the National Security Containers acquisition is not subject to this offering. National Security Containers leases portable storage units from its nine branches in Phoenix, Tucson, Dallas, San Antonio, Houston, Memphis, New Orleans, Denver and Colorado Springs. We have branches in six of these nine cities, and over time, we plan to integrate National Security Containers' operations with our existing branches in those cities. Through this acquisition, we will enter three new markets: Colorado Springs, Memphis and New Orleans. For the nine month period from April 1, 1998 to December 31, 1998, National Security Containers had revenues of about $7 million and operating income of about $1.8 million. Tulsa Branch. On March 31, 1999, we opened a start-up branch in Tulsa, Oklahoma. Increase in Credit Facility. Effective April 1, 1999, we amended our revolving credit facility to increase the maximum amount we can borrow from $75 million to $90 million. THE OFFERING The following table, and similar information throughout this prospectus relating to shares to be outstanding after this offering, assumes that the underwriters do not exercise the option we granted them to purchase up to 465,000 additional shares: Common stock offered by Mobile Mini..................... 2,500,000 shares Common stock offered by selling stockholders............ 600,000 shares Common stock to be outstanding after this offering...... 10,670,451 shares(1) Use of proceeds.........................................

9 RISK FACTORS This offering and our business involve various risks and uncertainties. You should carefully consider the risks and uncertainties described below and the other information in this prospectus before deciding whether to invest in our common stock. If any of the following risks and uncertainties actually occur, our business and results of operations could be materially adversely affected. This could cause the market price of our common stock to decline, and you may lose part or all of your investment. 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 management, human and other resources. Our anticipated future growth may 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 add managers and employees and improve our operating, financial and other internal procedures and controls. We also must effectively motivate, train and manage our employees. We cannot be sure that we can integrate 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 have to close unprofitable locations. Closing a branch 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 unit. We have a credit facility with a group of banks. Under the credit facility, we can borrow up to $90 million on a revolving loan basis, which means that amounts repaid may be reborrowed. As of April 1, 1999, we had borrowed $60.9 million under our credit facility, leaving $9.9 million available for further borrowing under the credit facility's borrowing base. Our high amount of debt makes us more vulnerable to 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 our 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 lease fleet utilization requirements. The terms of our credit facility also limit our capital expenditures, acquisitions, additional debt and repurchases of our common stock as well as 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. If we 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. This could require us to scale back 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 financing or equity capital on acceptable 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 7

10 financing or equity capital on acceptable terms, we may have to curtail our growth by delaying our lease fleet expansion or new branch openings. OUR OPERATING RESULTS AND FINANCIAL PERFORMANCE MAY FLUCTUATE 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. As a result, we experience lower lease fleet utilization rates during the first quarter of each year. Our results of operations may fluctuate significantly from period to period due to a variety of factors which affect demand for our portable storage units. These factors include: - general economic and industry conditions; - availability and cost of used ocean-going 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 timing and number of new branches we acquire or start-up; and - the introduction and timing of new products or features by ourselves or our competitors. THERE ARE RISKS TO OUR GROWTH 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 operations we acquire into our existing business structure; - the costs of completing an acquisition and then integrating and operating it could be higher than 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 DEMAND FROM SOME OF OUR CUSTOMERS In 1998, customers in the construction and retail industries accounted for a majority of our leasing and sales revenues. 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 SHIPPING CONTAINERS We purchase, refurbish and modify used ISO shipping containers in order to expand our lease fleet. The availability of these containers depends in part on the level 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 often decreases, and 8

11 the price of available containers 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 changes 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 We face competition from several local companies and usually from one or two regional companies in all of our current markets. Our competitors include lessors of storage units, used over-the-road trailers and other structures used for portable storage. We also compete with conventional fixed self-storage facilities to a lesser extent. We compete primarily in terms of product quality and availability, lease rates and customer service. 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 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. We may have to lower our lease rates because of greater competition. This would lower our 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 effect 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 manufacture portable storage units to add to our lease fleet and for sale. 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 acceptable to us. The raw materials we use are subject to price fluctuations that we cannot control. Changes in the cost of raw materials can 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 profitability will decline. 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. 9

12 SOME ZONING LAWS RESTRICT THE USE OF OUR STORAGE UNITS Most of our customers use our storage units to store their goods on their own properties. Local zoning laws in some of our markets do not allow some of our customers to keep portable storage units on their properties or do not permit portable storage units unless located out of sight from the street. If local zoning laws in one or more our markets no longer allow our units to be stored on customers sites, our business would be adversely affected. Also, we probably would not enter a new market where zoning laws do not allow our units to be stored on customers' sites. 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 available labor could require us to increase our wages 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. 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, the Environmental Protection Agency and the Immigration and Naturalization Service. 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. 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 problem. We generate waste and by-products from our painting operations, potentially exposing us to environmental liability or contamination. Federal or state agencies may impose more stringent disposal regulations for paint waste and by-products. This could increase our costs of manufacturing and refurbishing portable storage units. Our manufacturing plant in Maricopa, Arizona is located fairly near Mexico. The INS periodically reviews immigration status of our workforce. We believe that we adhere to the rigorous immigration status review procedures. However, if the INS were to determine that a significant number of our plant employees were not eligible for employment, our manufacturing could be interrupted and our costs could increase. WE DEPEND ON A FEW KEY MANAGEMENT PERSONS We are substantially dependent on the personal efforts and abilities of Richard E. Bunger, our founder and Chairman of the Board, 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 management persons could have a material adverse effect on our business and prospects for growth. We do not have employment agreements with any of these people. 10

13 INSIDERS HAVE SIGNIFICANT CONTROL Our executive officers and directors currently collectively own approximately 2,290,000 shares of our common stock and exercisable options to purchase 337,000 shares of common stock. After giving effect to this offering, these shares will represent approximately 21.5% of our outstanding common stock. After this offering, Richard E. Bunger, our founder and Chairman of the Board, will own approximately 16.2% of our common stock. This means that our executive officers and directors collectively, and Mr. Bunger individually, will continue to have substantial influence in the election of our Board of Directors and on the direction of our business.

14 USE OF PROCEEDS We estimate that the net proceeds from the sale of the 2,500,000 shares of common stock we are offering will be $29.5 million ($35.0 million if the underwriters exercise their over-allotment option in full), assuming a public offering price of $12.6875 per share, after deducting estimated underwriting discounts and commissions and offering expenses. We will not receive any proceeds from the selling stockholders' sale of 600,000 shares of common stock. We intend to use the net proceeds to fund our fleet and branch expansion, for working capital and to pay a portion of the purchase price for our pending acquisition of the assets of National Security Containers, L.L.C. Pending these uses, we will use the net proceeds to reduce borrowings outstanding under our credit facility. If our acquisition of National Security Containers' assets closes before this offering is completed, we will have issued National Security Containers $8.0 million of our redeemable Series B convertible preferred stock, and we will use $8.0 million of the net proceeds to redeem the shares. If this acquisition closes after this offering is completed, we will use $8.0 million of the net proceeds to pay a portion of the purchase price for those assets and we will not issue any shares of our preferred stock. On April 1, 1999, we owed approximately $60.9 million under our credit facility. Interest on outstanding borrowings accrues at a variable rate, which was 7.0% at April 1, 1999.

18 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS You should read this discussion in conjunction with our financial statements and the other financial information in this prospectus. OVERVIEW Since 1996, we have transitioned our business to focus on the leasing of portable storage units rather than their sale. This has caused the composition of our revenues and expenses to change. Leasing revenues as a percentage of our total revenues grew to 69.2% in 1998 from 54.0% in 1997 and 42.1% in 1996. From the end of 1995 to the end of 1998, we increased the number of portable storage units in our lease fleet from 11,295 to 25,768, an increase of approximately 128%. Our leasing revenues include all rent we receive for our portable storage units and other structures. Our sales revenues include proceeds from the sale of portable storage units and other structures to customers. Our other revenues consist principally of charges for the delivery of the portable storage units. Our principal operating expenses include: cost of sales; leasing, selling and general expenses; and depreciation and amortization. Cost of sales includes both our cost to buy, refurbish, modify and transport 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. We expense our repair and maintenance costs as incurred, and we include them in leasing, selling and general expenses. Annual repairs and maintenance expenses on our leased units have averaged about 2.0% of our lease revenues during the past three years. Depreciation and amortization primarily includes depreciation of the portable storage units in our lease fleet. Our portable storage units are depreciated on the straight-line method over our units' estimated useful life of 20 years, with residual values estimated at 70% of our unit investment. 16

19 RESULTS OF OPERATIONS The following table shows the percentage of total revenues represented by the key items that make up our statements of operations: YEAR ENDED DECEMBER 31, ----------------------- 1996 1997 1998 ----- ----- ----- Revenues: Leasing................................................... 42.1% 54.0% 69.2% Sales..................................................... 55.7 44.5 29.7 Other..................................................... 2.2 1.5 1.1 ----- ----- ----- Total revenues......................................... 100.0 100.0 100.0 Costs and expenses: Cost of sales............................................. 47.0 31.5 20.4 Leasing, selling and general expenses..................... 36.2 44.7 48.8 Depreciation and amortization............................. 4.0 4.9 5.5 Restructuring charge...................................... 1.6 -- -- ----- ----- ----- Income from operations...................................... 11.2 18.9 25.3 Other income (expense): Interest income........................................... -- -- 0.1 Interest expense..........................................

(1.0) -- -- ----- ----- ----- Net income.................................................. 0.1% 4.8% 8.5% ===== ===== ===== 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. In 1998, we opened four new branches, three of which were through acquisitions. The new branches were in Las Vegas, Oklahoma City, Denver and Albuquerque. These new branches accounted for 15.8% of our increase in 1998 leasing revenues. Our existing eight branches accounted for 84.2% of the increase in our leasing revenues. Our revenues from the sale of portable storage units and other structures 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% 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. As a result, our fixed manufacturing expenses were allocated over more units and resulted in a higher gross margin on portable storage unit sales in 1998. Leasing, selling and general expenses increased by $5.1 million to 48.8% of total revenues in 1998 from 44.7% 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 17

20 started 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. However, these expenses decreased to 70.6% of our leasing revenues in 1998 from 82.8% in 1997. 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 other equipment added at our branches. Our operating margin increased to 25.3% of total revenues in 1998 from 18.9% in 1997 principally because we focused on leasing rather than selling portable storage units and because leasing, selling and general expenses decreased as a percentage 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 because we had 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 as a percentage of leasing revenues 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 the exercise of warrants we had issued in 1994 and common stock issued in connection with the acquisitions completed during 1998. 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, a 3.1% increase in our average rent per unit and $1.0 million from our loss limitation waiver program which we introduced in 1997. Our revenues from the sale of portable storage units and other structures decreased by 13.1% to $20.5 million in 1997 from $23.6 million in 1996 because we focused on leasing rather than selling our portable storage units 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 decision to stop selling lower margin modular buildings caused a substantial increase in our gross margin on sales during 1997. As a result, cost of sales declined to 70.9% of sales revenues in 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 had 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. However, these expenses declined to 82.8% of our leasing revenues in 1997, from 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 18

21 needed for manufacturing and equipment added at our branches. We recorded a restructuring charge in 1996 of $700,000. This related in part to our decision to discontinue manufacturing modular buildings. There was no similar charge in 1997. Our operating margin increased to 18.9% of total revenues 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 as described above. As a result, 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 because we had higher average debt outstanding during 1997. Our average debt outstanding increased by 40.8% due to the issuance of $6.9 million of 12% Senior Subordinated Notes 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. There was no similar charge in 1997. We reported net income in 1997 of $2.2 million, or $0.32 per diluted share of common stock, compared to 1996 net income, before the extraordinary charge, of $480,576, or $0.07 per diluted share of common stock. These increases were primarily because of our higher leasing revenues in 1997 and the higher gross margin on sales of units in 1997. Our effective tax rate declined to 40.0% in 1997 from 44.0% in 1996. Excluding the restructuring charge in 1996, 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, has 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 1997 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. 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 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. 19

22 During 1997, the net cash provided by financing activities was primarily from $9.5 million of net borrowings under our credit facility and proceeds from the issuance of $6.9 million 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. Since March 1996, our principal source of liquidity has been our credit facility, which now consists of a $90 million revolving line of credit and a $6 million term loan. The interest rate is determined quarterly, based on our ratio of funded debt to earnings before interest, taxes, depreciation and amortization. During 1998, the average interest rate under our credit facility was 7.7%. On April 1, 1999, the maximum amount that we can borrow under the revolving line of credit was increased from $75 million to $90 million. As of April 1, 1999, we had borrowed $60.9 million under our credit facility, leaving $9.9 million available for further borrowing under the credit facility's borrowing base. 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. Our credit facility also 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. We entered into an Interest Rate Swap Agreement in September 1998. This agreement effectively changes the interest rate on $30 million of our revolving line of credit so that the rate is based upon a spread from 5.5% rather than a spread from the Eurodollar rate. 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. These warrants have an exercise price of $5.00 per share. The 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. On April 3, 1999, we entered into an agreement to acquire substantially all of the assets of National Security Containers, L.L.C., a portable storage leasing company, for total consideration of $25.5 million. The closing of this acquisition is subject to a number of conditions but is expected to close before the end of April 1999. We intend to pay $8 million of the purchase price from the proceeds we receive from this offering. We will borrow $17.5 million under our credit facility to pay the rest of the purchase price. We believe that our working capital, together with our cash flow from operations, net proceeds from this offering and borrowings under our credit facility will be sufficient to fund our operations and planned growth for the next 12 months. We believe that to maintain our historical growth rates, we will need to obtain additional debt financing and raise additional equity capital by issuing additional shares of our stock. However, we cannot be sure that we will be able to obtain the necessary debt financing or equity capital on acceptable terms. SEASONALITY During the past three years, our operations as a whole have not been very seasonal. Demand for leases of our portable storage units is stronger from September through December because 20

23 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 slightly lower cash flow during the first quarter of each year. 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. 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 primary 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. We believe that with modifications to existing software, conversions to new software and replacement of some hardware, we can satisfactorily resolve the year 2000 issue in our own internal operating systems by the third quarter of 1999. We have established an internal auditing process to track and verify the results of our plan and tests. Suppliers and Customers. We are currently evaluating the year 2000 readiness of our important suppliers and larger leasing customers. We have forwarded questionnaires to all of our major suppliers and will evaluate responses on a case-by-case basis. We are focusing this review on our primary vendors, such as steel, paint and other suppliers, and on our phone systems. If any of our suppliers are not year 2000 compliant in a timely manner, we could experience a shortage in supplies of materials, which could adversely affect the growth of our lease fleet. We also sent questionnaires to our larger leasing customers for the year 2000 issue. If our larger customers are not year 2000 compliant, 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 lead lender under our credit facility that the year 2000 is not expected to cause delays or other problems with 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. If the third party service providers that we depend on are not year 2000 compliant in a timely manner, our operations could be disrupted. We are developing a contingency plan to address financial and operating problems that might arise on January 1, 2000. This contingency plan will include identifying back-up processes that do not rely on computers whenever possible. For example, systems are already in place that will allow us to lease portable storage units by using manual forms if there is a communications failure between our branches and headquarters. 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 our current estimates. These estimates reflect our assumptions about future events, including the continued availability of third party goods and services, as well as the timing and effectiveness of third parties' remediation plans. We 21

24 cannot be sure that these estimates will be achieved, and our actual results could differ materially from our plans. Specific factors that could cause 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 timeliness and effectiveness of remediation efforts of third parties. 22

25 BUSINESS We believe we are the nation's largest provider of portable storage solutions through our lease fleet of over 26,000 portable storage units. We currently operate 13 branches located in seven southwestern and western states. Our products provide secure, accessible temporary storage for a diversified customer base of over 28,000 customers, including Wal-Mart, Motorola, Frito Lay, Holiday Inns, Target, the City of Phoenix and the Department of Defense. Our customers use our products for a wide variety of storage applications, including retail and manufacturing inventory, construction materials and equipment, documents and records and household goods. We obtain our portable storage units by purchasing used ISO containers, 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 customized 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. In 1996, we initiated a strategy of focusing on leasing rather than selling portable storage units. Since then, we have been expanding our lease fleet. We believe our leasing model is highly attractive because portable storage units: - Provide predictable, recurring revenues from leases with an average duration of 20 months. - Have average monthly rental rates which recoup our unit investment in 26 months. - Have useful lives exceeding 20 years, low maintenance and high residual values. - Produce incremental leasing operating margins above 60%. As a result of shifting our focus to leasing, we have achieved substantial increases in our revenues and profitability. In the past three years, our leasing revenues have increased from $15.5 million to $36.5 million, and we have achieved internal growth exceeding 30% compounded annually. Over the same period, we have increased our operating income from $4.6 million to $13.3 million and improved our operating margin from 11.4% to 25.3%. INDUSTRY OVERVIEW The storage industry includes two principal segments, fixed self-storage and portable storage. The fixed self-storage segment consists of permanent structures located away from customer 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 differs from the fixed self-storage segment because it brings the storage solution to the customer's location and addresses the need for secure, temporary storage with immediate access. The advantages of portable storage include convenience, immediate accessibility, better security and lower price. 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 the size of the market is expanding due to increasing awareness of the advantages of portable storage. Our products also serve the mobile office industry. This industry provides temporary office space and is estimated to exceed $2 billion. We have also recently introduced portable records storage units. The documents and records storage industry is experiencing significant growth as businesses continue to generate substantial paper records that must be kept for extended periods. 23

26 Our goal is to become the leading national provider of portable storage solutions. We believe that our competitive strengths and growth strategy, as outlined below, will help us achieve this goal. COMPETITIVE STRENGTHS Market Leadership. We have a lease fleet of over 26,000 portable storage units and are the largest provider of portable storage solutions in a majority of our markets. We believe we are creating brand awareness and that "Mobile Mini" is associated with high quality portable storage products and superior customer 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 the industry's broadest 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, while 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 usable 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, electrical wiring, shelving and other customized features. Customer Service Focus. We believe that the portable storage industry is highly service intensive and essentially local. Our entire organization is focused on providing high levels of customer service. 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. 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. Our sales people work out of our local 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. Diverse Customer Base. We have more than 28,000 customers across a wide range of industries and believe this diversity reduces our susceptibility to economic downturns in our markets or in any of the industries in which our customers operate. Our diverse customer base also demonstrates the broad applications for our products and the opportunity to create future demand through target marketing. Our customers include retailers, wholesalers, commercial businesses, contractors, consumers, governmental agencies, hospitals and schools. Our two largest customers accounted for only 4.3% and 2.1% of our 1998 lease revenues (excluding ancillary revenues). Customized Management Information Systems. We have recently made substantial investments in our management information systems to optimize fleet utilization, capture detailed customer data, improve financial performance and support our growth. Our management information 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 an average annual utilization rate of our lease fleet above 85% over the last three years while growing the size of the lease fleet by 128% to over 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 24

27 linked through a scaleable PC-based wide area network that provides real-time transaction processing and detailed reports on a branch by branch basis. Flexibility Afforded By Manufacturing Capability. We design and manufacture our own portable storage units in addition to refurbishing and modifying used ISO shipping containers. This capability allows us to offer a wide range of products and proprietary features to better meet our customers' needs, charge premium lease rates and gain market share from our competitors with more limited product offerings. Our manufacturing capability also provides us with an additional supply of units to support our growth. GROWTH STRATEGY Focus on Core Portable Storage Leasing Business. We will continue to focus on growing our core leasing business and lease fleet because they provide predictable, recurring revenues and high operating margins. We believe there is substantial demand for leasing our portable storage units throughout the United States. Our focus on leasing has allowed us to achieve a compounded annual growth rate of 33% in leasing revenues and 43% in operating income over the past three years. Increase Penetration in Existing Markets. We intend to increase the number of portable storage units we lease from our existing branches to both new and repeat customers. We have historically been able to generate strong internal growth within our existing markets through aggressive marketing and lease fleet growth. Over the last three years, we generated compounded annual leasing revenue increases of 31% in our existing eight markets. We believe that by increasing awareness of the benefits of portable storage and through our targeted marketing and advertising programs, we can continue to increase leasing revenues and generate internal growth. Accelerate Branch Expansion. We believe our branch model can be introduced to many more markets in the United States. 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 plan to enter a new market by acquiring the storage units and leases of an operating business. Where there are no quality acquisitions available to us, we plan to enter targeted markets through start-up branches. We intend to accelerate our branch openings to capitalize on our market opportunity. Develop New Products. Through an active research and development effort, we have historically been able to introduce new products and features to expand the applications and overall market for our storage products. Recent examples include our 10-foot wide unit, which provides 40% more usable storage space than a standard eight-foot wide unit. In addition, we recently completed the design of a records storage unit which provides highly secure, easily accessible on-site storage of records and documents. We believe our design and manufacturing capabilities increase our ability to service our customers' needs and help create demand for our portable storage solutions. PRODUCTS We provide a broad range of portable storage products to meet our customers' varying needs. Our products and 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. 25

28 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. - 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 one of our three branches with assembly capabilities. 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 records storage units enable customers to store documents 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, with a high level of fire and water damage protection. Mobile Offices - We manufacture mobile office units that range from 10 to 40 feet in length. We offer these 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. Our office units are equipped with electrical wiring, heating and air conditioning, phone jacks, carpet or tile, proprietary doors and windows with security bars. We believe our office units provide the advantage of ground accessibility for ease of access and high security in an 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 our unit investment. For the past three years, our cost to repair and maintain our portable storage units has averaged approximately 2% of our lease revenues. Repainting the outside of storage units is the most frequent maintenance item. BRANCH OPERATIONS We locate our branches in markets 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 visible from high traffic roads as an effective way to advertise our products and our name. Our branches maintain an inventory of portable storage units available for lease, and a majority of our branches also provide 26

29 branch storage of units under lease. The following table shows information about our branches: LOCATION FUNCTIONS SIZE YEAR ESTABLISHED - -------- --------- -------- ---------------- Phoenix, Arizona Leasing, on-site storage, sales 10 acres 1983 Tucson, Arizona Leasing, on-site storage, sales 5 acres 1986 Los Angeles, California Leasing, on-site storage, 10 acres 1988 sales, refurbishment and assembly San Diego, California Leasing, on-site storage, sales 5 acres 1994 Dallas, Texas Leasing, on-site storage, 17 acres 1994 sales, refurbishment and assembly Houston, Texas Leasing, on-site storage, 7 acres 1994 sales, refurbishment and assembly San Antonio, Texas Leasing, on-site storage, sales 3 acres 1995 Austin, Texas Leasing, on-site storage, sales 5 acres 1995 Las Vegas, Nevada Leasing and sales 1 acre 1998 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 Tulsa, Oklahoma Leasing and sales 1 acre 1999 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 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. SALES AND MARKETING We have 60 people at our branches and seven people in management at our headquarters that conduct sales and marketing on a full-time basis. We believe that by locating most of our sales and marketing staff in our branches, we can better understand the portable storage needs of our customers and provide 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 sales and marketing training programs covering all aspects of leasing and customer service. Our branches communicate with one another and with headquarters through our management information system. This enables the sales and marketing team 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 employees are 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. 27

30 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 existing and prospective customers. These brochures describe our products and features and highlight the advantages of portable storage. 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 single customer accounted for only 4.3% of our leasing revenues, and our next largest customer accounted for only 2.1% of our leasing revenues (excluding ancillary revenues). We target customers who can benefit from our portable storage solutions either for seasonal, temporary or long-term storage needs. Customers use our portable storage units for a wide range of purposes. The following table provides an overview at December 31, 1998 of our customers and how they use our portable storage units: APPROXIMATE PERCENTAGE OF UNITS REPRESENTATIVE TYPICAL BUSINESS ON LEASE CUSTOMERS APPLICATIONS - -------- ------------------- -------------- ------------ Retail 40% Department, drug, grocery and Inventory storage and strip mall stores, hotels, record storage restaurants, dry cleaners and service stations Construction 31% General, electrical, plumbing and Equipment and mechanical contractors, materials storage and landscapers and residential job site offices homebuilders Consumers 15% Homeowners Backyard storage and storage of household goods during reloca- tion or renovation Industrial, 8% Distributors, trucking and utility Raw materials and commercial and companies, farming, agriculture, equipment storage in- other finance and insurance companies, plant offices and real estate brokers and film document storage production companies Schools, hospitals 4% Hospitals, medical centers and Athletic equipment and other schools storage and disaster institutions preparedness supplies and record storage Governmental agencies 2% Military, Native American tribal Storage of supplies, governments and reservations and records and equip- Federal, state, county and local ment agencies MANUFACTURING We build new portable storage units, mobile offices and custom-designed structures at our Maricopa, Arizona manufacturing plant. Our manufacturing process includes cutting, shaping and welding raw steel, installing customized features and painting the newly constructed units. 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 one of our three branches with assembly capabilities. We can ship up to twelve, 20-foot containers on a single flat-bed trailer. By comparison, only two or 28

31 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 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 protects 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 conditions. Should the price of used ISO shipping containers increase substantially, we can increase our manufacturing volume and reduce the number of used containers we buy and refurbish. MANAGEMENT INFORMATION SYSTEMS We use a customized management information system in an effort to optimize lease fleet utilization and the effectiveness of our sales and marketing. 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 with leasing volume, fleet utilization, lease rates and fleet movement as well as monthly profit and loss statements on a consolidated and branch basis. 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 also use the system to track customer leads and other sales data, including information about current and prospective customers. LEASE TERMS Our leases have an average initial term of over eight months and provide for the lease 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. Each lease provides that the customer is responsible for the cost of delivery at lease inception and pickup at lease termination. Our leases specify that the customer is liable for any damage done to the unit beyond ordinary wear and tear. However, our customers may purchase a damage waiver from us to avoid this liability. This provides us with an additional source of recurring revenue. The customer's possessions stored within the portable storage unit are the responsibility of the customer. COMPETITION We face competition from several local companies and usually one or two regional companies in all of our current markets. Our competitors include lessors of storage units, used over-the-road trailers and other structures used for portable storage. We also compete with conventional fixed self-storage facilities to a lesser extent. We compete primarily in terms of product quality and availability, lease rates and customer service. 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. 29

32 In addition to competition for customers, we face competition in purchasing used ISO shipping containers. Several types of businesses purchase used shipping ISO 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 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. 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. We may have to lower our lease rates because of greater competition. This would lower our 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 effect on our business and results of operations. 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 and marketing......................................... 60 Manufacturing............................................... 503 Drivers and storage unit handling........................... 165 Our employees are not represented by a labor union. We consider our relations with our employees to be good. PROPERTIES We own our branch locations in Dallas, Texas and Oklahoma City, Oklahoma. We lease the other branch locations. We believe that satisfactory alternative properties can be found in all of our markets at the end of the leases, if necessary. We own our manufacturing facility in Maricopa, Arizona, which is 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 if desired. LITIGATION 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. 30

38 DESCRIPTION OF COMMON STOCK AND OTHER SECURITIES GENERAL Our Certificate of Incorporation authorizes the issuance of 17,000,000 shares of common stock and 5,000,000 shares of preferred stock. As of March 31, 1999, 8,170,451 shares of common stock were outstanding, and we had reserved 1,095,375 shares of common stock for issuance upon exercise of outstanding options and warrants. No shares of preferred stock were outstanding on March 31, 1999. We may issue shares of our redeemable Series B convertible preferred stock in connection with our acquisition of the assets of National Security Containers, L.L.C. COMMON STOCK The holders of common stock have one vote per share on all matters submitted to a vote of our stockholders. Holders of common stock are entitled to receive any dividends on the common stock declared by the Board of Directors out of funds legally available for dividend payments. If we dissolve, liquidate or wind up our business, the holders of common stock will share ratably in our assets after payment of our liabilities and any preferences on the preferred stock. All outstanding shares of common stock are fully paid and nonassessable. The holders of common stock do not have any rights to acquire or subscribe for additional shares. Accordingly, if you buy shares in this offering and we later decide to sell additional shares, you will have no right to purchase any of those additional shares. Therefore, your percentage interest would be reduced. Under our Bylaws, the holders of one-third of the outstanding shares of our common stock, if present in person or by proxy, represent a quorum for the transaction of business at our stockholders meetings. In most instances, if holders of a majority of the common stock present in person or by proxy at any meeting vote "for" a matter, including the election of directors, the matter passes. The holders of common stock do not have cumulative voting rights. This means the holders of more than half of the outstanding shares of our common stock can elect all of the directors if they choose to do so, and the priority stockholders cannot elect any Directors. The Board of Directors is allowed to fill any vacancies on the Board between stockholders' meetings. PREFERRED STOCK Under our Certificate of Incorporation, the Board of Directors may issue shares of preferred stock without stockholder approval. The Board may set the rights, privileges and preferences of any series of preferred stock it decides to issue. This includes the dividend rate and voting rights, redemption rights, sinking fund, liquidation preferences and conversion rights. Therefore, the rights of any preferred stock the Board of Directors may decide to issue could adversely affect the voting power or other rights of the holders of the common stock. We do not currently intend to issue any preferred stock other than our redeemable Series B convertible preferred stock which is described below and which may be issued in connection with our acquisition of the assets of National Security Containers. See "Use of Proceeds." At the closing of that acquisition, we will issue National Security Containers, L.L.C. 640,000 shares of our Series B preferred stock, with a mutually agreed aggregate value of $8 million. The rights and preferences we expect to adopt for the Series B preferred stock are described below. If the offering of our common stock pursuant to this prospectus is complete before the closing of the asset acquisition, we will not issue any shares of preferred stock, but will instead pay the entire purchase price in cash. Dividends. Dividends on the Series B preferred stock will accrue at the rate of 5% per year for the first six months the shares are issued and at a rate of 12% per year after that six month period. Dividends are payable quarterly in cash out of funds legally available for use in the payment of dividends. If we fail to redeem the shares of Series B preferred stock when required, 36

39 or if we fail four times to pay dividends on a quarterly payment date, dividends begin to accrue at a rate of 18% per year. Conversion. After the first anniversary of issuance, if not redeemed earlier, each share of Series B preferred stock will become convertible into one share of our common stock (subject to certain adjustments), at the option of the owner of the share. If not previously redeemed, all the shares of Series B preferred stock would be convertible into 640,000 shares of our common stock, assuming no adjustments had to be made to the $12.50 per share initial conversion price. Redemption. We may redeem all or any of the shares of Series B preferred stock at any time. On the second anniversary of the issuance of the shares of Series B preferred stock, we will be required to redeem all outstanding shares. Also, if there is a change in control of Mobile Mini, we will be required to redeem all of the Series B preferred stock. In addition, if after issuing the Series B preferred stock, we complete an offering of our equity securities or subordinated debt securities, up to one-half of the net proceeds of each offering must be used to redeem shares of Series B preferred stock. The redemption price of the Series B preferred stock is $12.50, plus all accrued and unpaid dividends. Liquidation Preference. Upon our liquidation, dissolution or winding-up, each share of Series B preferred stock will be entitled to receive $12.50 plus all accrued but unpaid dividends, before any distribution can be made on our common stock. After receiving that liquidation preference payment, the Series B preferred stock will not be entitled to further participate in liquidation distributions. However, if at the time we liquidate, dissolve or wind-up, we also have failed to redeem the shares of Series B preferred stock when required, or if we failed four times to pay dividends on a quarterly payment date, after receiving the liquidation preference payment, the shares of Series B preferred stock will be entitled to participate in distributions made on the common stock, based upon the number of shares of common stock then issuable upon conversion of a share of Series B preferred stock. Voting Rights. Initially, the Series B preferred stock will not entitled to vote, except as provided by Delaware law. However, if we fail to redeem the shares of Series B preferred stock when required, or if we fail four times to pay dividends on a quarterly payment date, the Series B preferred stock will be entitled to vote with the holders of common stock as a single class, with each share of Series B preferred stock having that number of votes equal to the number of shares of common stock into which it is convertible. Registration Rights. We will grant National Security Containers rights to demand registration of the shares of common stock issuable upon conversion of the shares of Series B preferred stock and rights to include shares of common stock in other registrations effected by us. These rights will be generally transferable. WARRANTS In October 1997, we issued warrants to purchase 187,500 shares of common stock in connection with the sale of our 12% Senior Subordinated Notes. Those warrants are exercisable at $5.00 per share and expire on November 1, 2002. As of March 31, 1999, warrants to purchase 182,625 shares of common stock were outstanding. CLASSIFIED BOARD OF DIRECTORS AND RELATED PROVISIONS We have also set up a classified Board of Directors. This means that our directors serve staggered terms of three years each. This classified board structure means that stockholders who do not approve of the policies of the Board of Directors cannot vote to remove more than one-third of the directors at any one annual meeting. It will take two annual meetings of stockholders to remove a majority of the Board. TRANSFER AGENT The transfer agent for our common stock is Harris Trust and Savings Bank, Chicago, Illinois. 37

40 PLAN OF DISTRIBUTION The underwriters named below, through their representatives, BT Alex. Brown Incorporated, A.G. Edwards & Sons, Inc., Morgan Keegan & Company, Inc. and Peacock, Hislop, Staley & Given, Inc., have severally agreed to purchase from us and the selling stockholders the following numbers of shares of common stock at the public offering price less the underwriting discounts and commissions shown on the cover page of this prospectus. UNDERWRITER NUMBER OF SHARES - ----------- ---------------- BT Alex. Brown Incorporated.............................. A.G. Edwards & Sons, Inc................................. Morgan Keegan & Company, Inc. ........................... Peacock, Hislop, Staley & Given, Inc. ................... --------- Total.......................................... 3,100,000 ========= We and the selling stockholders have entered into an underwriting agreement with the underwriters which provides that the underwriters are obligated, subject to the terms and conditions of the underwriting agreement, to purchase all of the shares of common stock being offered, other than those covered by the over-allotment option described below, if any of such shares are purchased. The underwriters propose to offer the shares of common stock to the public at the public offering price shown on the cover page of this prospectus and to dealers at a price that represents a concession not in excess of $ per share under the public offering price. The underwriters may allow, and dealers may re-allow, a concession not in excess of $ per share to other dealers. After the public offering, the offering price and other selling terms may be changed by the representatives of the underwriters. The underwriters may sell more shares that the total number shown on the above table. To cover these sales, we have granted to the underwriters an option, exercisable not later than 30 days after the date of this prospectus, to purchase up to 465,000 additional shares of our common stock at the public offering price less the underwriting discounts and commissions shown on the cover page of this prospectus. The underwriters may exercise this option only to cover these sales. To the extent that the underwriters exercise their option, each of the underwriters will become obligated to purchase approximately the same percentage of additional shares of common stock as the number of shares of common stock to be purchased by it in the above table bears to 3,100,000, and we will be obligated to sell such shares to the underwriters. If any additional shares of common stock are purchased, the underwriters will offer additional shares on the same terms as those on which the initial shares are being offered. We and certain selling stockholders have agreed to indemnify the underwriters against liabilities in connection with this offering, including liabilities under the Securities Act of 1933. 38

41 The representatives of the underwriters have advised us that the underwriters do not intend to confirm sales to any account over which they exercise discretionary authority. To facilitate this offering, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the market price of our common stock. Specifically, the underwriters may over-allot shares of our common stock in connection with this offering by creating a short position in our common stock for their own accounts. A short position results when an underwriter sells more shares of common stock than that underwriter is committed to purchase. Additionally, to cover these over-allotments or to stabilize the market price of our common stock, the underwriters may bid for, and purchase, shares of our common stock in the open market at a level above that which might otherwise prevail in the open market. Finally, the representatives, on behalf of the underwriters, may also reclaim selling concessions allowed to an underwriter or a dealer if the underwriting syndicate repurchases shares distributed by that underwriter or dealer. Any of these activities may maintain the market price of our common stock at a level above that which might otherwise prevail in the open market. The underwriters are not required to engage in these activities, and if commenced, may end any of these activities at any time. Our directors and executive officers collectively hold approximately 2,290,000 shares of our common stock and exercisable options to buy approximately 337,000 shares of common stock, after giving effect to the sale of 500,000 shares by Richard E. Bunger. Our directors and executive officers have agreed with the underwriters, subject to certain limited exceptions, not to offer, sell, pledge or otherwise dispose of any shares of common stock owned by them for a period of one year following the date of this offering without the prior written consent of BT Alex. Brown Incorporated. We have agreed with the underwriters not to offer, sell, pledge or otherwise dispose of any shares of our common stock for a period of one year from the date of this offering without the prior written consent of BT Alex. Brown Incorporated, except that we may issue, and grant options or warrants to purchase, shares of our common stock or any shares convertible into, exercisable for or exchangeable for shares of our common stock, upon the exercise of outstanding options and warrants and our issuance of options and stock granted under the existing stock option plan and in connection with acquisition transactions. In connection with this offering, some of the underwriters and selling group members (if any) who are qualified market makers in our common stock may engage in passive market making transactions in our common stock on the Nasdaq National Market in accordance with Rule 103 of Regulation M under the Exchange Act, during the business day prior to the pricing of this offering before the commencement of offers or sales of the common stock. Passive market makers must comply with applicable volume and price limitations and must be identified as such. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid of such security; if all independent bids are lowered below the passive market makers' bid, however, such bid must then be lowered when certain purchase limits are exceeded. Passive market making may stabilize the market price of our common stock at a level above that which might otherwise prevail and, if commenced, may be discontinued at any time. BT Commercial Corporation, an affiliate of BT Alex. Brown Incorporated, is the agent for our lenders under our $90 million credit facility. We believe the interest rate and other terms and conditions of our credit facility are within standard industry parameters. VALIDITY OF THE SHARES The validity of the common stock offered hereby will be passed upon for the Company by Bryan Cave LLP, Phoenix, Arizona. Piper & Marbury L.L.P., Baltimore, Maryland, will pass upon certain legal matters as requested by the underwriters. 39

45 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.

50 SUPPLEMENTAL DISCLOSURE OF NONCASH FINANCING ACTIVITIES: In 1998, the Company issued 85,468 shares of the Company's common stock valued at $500,000 as partial consideration in the purchase price of Nevada Storage Containers (Las Vegas, Nevada) and issued 18,022 shares of the Company's common stock valued at $184,000 as partial consideration in the purchase price of Aspen Instant Storage (Oklahoma City, Oklahoma). In 1997, the Company issued 60,000 shares of the Company's common stock and 15,000 warrants to purchase the Company's common stock as consideration for services performed in connection with the $6.9 million subordinated debt offering and related bridge financing with an aggregate value of $357,675 (Note 6). Capital lease obligations of $548,697 and $210,740 during 1996 and 1998, respectively, were incurred in connection with lease agreements for equipment. The Company did not enter into any capital lease obligations during 1997. The accompanying notes are an integral part of these consolidated statements. F-7

51 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. F-8

52 MOBILE MINI, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 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. CONCENTRATION 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 ---- ---- Retail...................................................... 46% 40% Construction................................................ 24% 31% Consumers................................................... 17% 15% Commercial.................................................. 4% 7% Government and Institutions................................. 7% 6% Other....................................................... 2% 1% 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. F-9

53 MOBILE MINI, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 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: 1997 1998 ---------- ---------- Raw materials and supplies........................ $3,241,962 $6,480,553 Work-in-process................................... 631,399 801,338 Finished portable storage units................... 874,955 1,268,887 ---------- ---------- $4,748,316 $8,550,778 ========== ========== 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: ESTIMATED USEFUL LIFE IN YEARS 1997 1998 ----------- ----------- ----------- Land............................... $ 708,555 $ 777,668 Vehicles and equipment............. 5 to 10 12,721,917 15,963,099 Buildings and improvements......... 30 6,739,190 7,211,833 Office fixtures and equipment...... 5 to 20 3,109,904 3,404,320 ----------- ----------- 23,279,566 27,356,920 Less -- Accumulated depreciation... (5,267,650) (7,094,182) ----------- ----------- $18,011,916 $20,262,738 =========== =========== Property, plant and equipment includes assets acquired under capital leases of approximately $603,000 and $818,000, and accumulated amortization of 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 F-10

54 MOBILE MINI, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 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. Below are the required disclosures pursuant to SFAS No. 128 for the years ended December 31, 1996, 1997 and 1998: 1996 1997 1998 ---------- ---------- ---------- Basic earnings per share: Net income............................... $ 70,222 $2,200,396 $4,483,967 ========== ========== ========== Weighted average common shares........... 6,737,592 6,752,147 7,839,623 ---------- ---------- ---------- Basic earnings per share.............. $ 0.01 $ 0.33 $ 0.57 ========== ========== ========== Diluted earnings per share: Net income............................... $ 70,222 $2,200,396 $4,483,967 ========== ========== ========== Weighted average common shares........... 6,737,592 6,752,147 7,839,623 Options and warrants assumed converted... 6,637 48,156 577,545 ---------- ---------- ---------- Weighted average common shares plus assumed conversion.................... 6,744,229 6,800,303 8,417,168 ---------- ---------- ---------- Diluted earnings per share............ $ 0.01 $ 0.32 $ 0.53 ========== ========== ========== 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. F-11

55 MOBILE MINI, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 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. 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. F-12

56 MOBILE MINI, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 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 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, F-13

57 MOBILE MINI, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 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. (4) NOTES PAYABLE: Notes payable at December 31 consist of the following: 1997 1998 ---------- ---------- Notes payable to BT Commercial Corporation, interest ranging from 2.25% over Eurodollar rate (5.3125% at December 31, 1998) to 0.75% over prime (7.75% at December 31, 1998), fixed monthly installments of principal plus interest, due March 2002, secured by various classes of the Company's assets............................ $4,500,000 $3,687,500 Notes payable, interest ranging from 10.5% to 12.2%, monthly installments of principal and interest, due October 1999 through May 2002, secured by equipment and vehicles............... 848,926 591,186 Notes payable, interest ranging from 11.49% to 12.63%, monthly installments of principal and interest, due July 2000 through January 2001, secured by portable storage units............... 558,032 385,418 Notes payable to financial institution, interest ranges from 6.49% to 7.75%, payable in fixed monthly installments due January 1999 through May 1999, unsecured............................. 216,091 155,872 ---------- ---------- $6,123,049 $4,819,976 ========== ========== Future maturities under notes payable are as follows: YEARS ENDING DECEMBER 31, ------------------------- 1999......................................... $1,526,391 2000......................................... 1,543,373 2001......................................... 1,405,089 2002......................................... 345,123 ---------- $4,819,976 ========== (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. F-14

58 MOBILE MINI, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 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. 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 2001......................................... 95,254 2002......................................... 40,836 2003......................................... 84,920 ---------- Total payments........................... 3,500,865 Less: Amounts representing interest...... (304,844) ---------- $3,196,021 ========== 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 an exercise price of $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 F-15

59 MOBILE MINI, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 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. The provision for income taxes at December 31, 1996, 1997 and 1998 consisted of the following: 1996 1997 1998 -------- ---------- ---------- Current...................................... $ -- $ -- $ -- Deferred..................................... 378,000 1,467,000 2,989,000 -------- ---------- ---------- Total.............................. $378,000 $1,467,000 $2,989,000 ======== ========== ========== The components of the net deferred tax liability at December 31, are as follows: 1997 1998 ----------- ------------ Deferred Tax Assets (Liabilities): Net operating loss carryforward............. $ 4,286,000 $ 8,303,000 Allowance for doubtful accounts............. 354,000 434,000 Alternative minimum tax credit.............. 211,000 211,000 Other....................................... 220,000 307,000 Accelerated tax depreciation................

60 MOBILE MINI, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 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. 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. F-17

61 MOBILE MINI, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 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: 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 F-18

62 MOBILE MINI, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 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: 1996 1997 1998 -------------------------- -------------------------- -------------------------- WEIGHTED WEIGHTED WEIGHTED NUMBER OF AVERAGE NUMBER OF AVERAGE NUMBER OF AVERAGE SHARES EXERCISE PRICE SHARES EXERCISE PRICE SHARES EXERCISE PRICE --------- -------------- --------- -------------- --------- -------------- Options outstanding, beginning of year.... 241,000 $4.04 347,000 $3.89 552,000 $3.80 Granted................ 156,000 3.43 206,500 3.64 212,750 6.87 Canceled/Expired.......

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 ========== F-20

64 MOBILE MINI, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 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 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 ========== F-21

65 MOBILE MINI, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 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. (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.

The Registrant estimates that expenses in connection with the offering described in this registration statement (other than underwriting and brokerage discounts and commissions) will be as follows: SEC Registration Fee........................................ $ 12,574 NASD Registration Fee....................................... 4,956 Nasdaq Application Fee...................................... 17,500 Printing and Engraving Fees................................. 80,000 Legal Fees and Expenses..................................... 100,000 Accounting Fees and Expenses................................ 75,000 Miscellaneous Expenses...................................... 59,970 -------- Total....................................................... $350,000 ======== All amounts except the SEC and NASD registration fees are estimated. ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS. The Registrant's Certificate of Incorporation and Bylaws provide that the Registrant will indemnify its directors and executive officers and may indemnify its other officers, employees and other agents to the fullest extent permitted by Delaware law. In addition, the Registrant's Certificate of Incorporation provides that, to the fullest extent permitted by Delaware law, the Registrant's directors will not be liable for monetary damages for breach of the directors' fiduciary duty of care to the Registrant and its stockholders. This provision in the Certificate of Incorporation does not eliminate the duty of care, and in appropriate circumstances equitable remedies such as an injunction or other forms of non-monetary relief would remain available under Delaware law. Each director will be subject to liability for breach of the director's duty of loyalty to the Registrant, for acts or omissions not in good faith or involving intentional misconduct or knowing violations of law, for acts or omissions that the director believes to be contrary to the best interests of the Registrant or its stockholders, for any transaction from which the director derived an improper personal benefit, for acts or omissions involving a reckless disregard for the director's duty to the Registrant or its stockholders when the director was aware or should have been aware of a risk of serious injury to the Registrant or its stockholders, for acts or omissions that constitute an unexcused pattern of inattention that amounts to an abdication of the director's duty to the Registrant or its stockholders, for improper transactions between the director and the Registrant and for improper distributions to stockholders and loans to directors and officers.

UNDERTAKINGS. (a) The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement; (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to II-3

71 Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer, or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(xx) The Company confirms as of the date hereof that it is in compliance with all provisions of Section 1 of Laws of Florida, Chapter 92-198, An Act Relating to Disclosure of doing Business with Cuba, and the Company further agrees that if it commences engaging in business with the government of Cuba or with any person or affiliate located in Cuba after the date the Registration Statement becomes or has become effective with the Commission or with the Florida Department of Banking and Finance (the "Department"), whichever date is later, or if the information in the Prospectus, if any, concerning the Company's business with Cuba or with any person or affiliate located in Cuba changes in any material way, the Company will provide the Department notice of such business or change, as appropriate, in a form acceptable to the Department. -7-

8 (xxi) The Company has conducted an inventory and review of the hardware, software, and embedded microcontrollers in noncomputer equipment (the "Computer Systems") used by it in its business in order to determine whether the Computer Systems are Year 2000 Compliant (as defined below). The Company has determined that the Computer Systems are Year 2000 Compliant. The Company has exercised due care in assessing whether the Computer Systems are Year 2000 Compliant and in assessing the Year 2000 Compliance status of its customers, suppliers and vendors. To the Company's knowledge, all of the Computer Systems of its customers, vendors and suppliers are Year 2000 Compliant to the extent they are in any way involved with the business of the Company. In addition, the Seller has not taken any action which will render any third-party software products non-Year 2000 Compliant. The Company has not received a "Year 2000 Deficiency Letter" or criticism from any person on the subject of Year 2000 Compliance. The phrase "Year 2000 Compliant" means technology, including but not limited to, information technology embedded systems, or any other electro-mechanical or processor-based system, when used in connection with its associated documentation, that is capable of accurately processing, providing, or receiving date data from, into, and between the twentieth and twenty-first centuries, and the years 1999 and 2000, including leap year calculations. (xxii) Except as would not result in a material adverse change in the earnings, business, management, properties, assets, rights, operations, condition (financial or otherwise) or prospects of the Company and of the Subsidiaries taken as a whole, whether or not arising in the ordinary course of business, or prevent the consummation of the transactions contemplated hereby, the Company and each of the Subsidiaries: (i) have obtained all licenses, permits, easements, grants, consents, certificates, approvals and orders (the "Approvals") which are required to be obtained under all applicable federal, state, foreign or local laws or any regulation, code, plan, order, decree, judgment, notice or demand letter issued, entered, promulgated or approved thereunder relating to pollution or protection of the environment, including laws relating to emissions, discharges, releases or threatened releases of pollutants, contaminants, or hazardous or toxic materials or waste into ambient air, surface water, ground water, or land or otherwise relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport, or handling of pollutants, contaminants or hazardous or toxic materials or wastes by the Company or any of the Subsidiaries or their respective agents ("Environmental Laws"); (ii) are in compliance with all terms and conditions of such required Approvals, and also are in compliance with all other limitations, restrictions, conditions, standards, prohibitions, requirements, obligations, schedules and timetables contained in the Environmental Laws; (iii) have not received notice of any past or present violations of Environmental Laws or any event, condition, circumstance, activity, practice, incident, action or plan which is reasonably likely to interfere with or prevent continued compliance with or which would give rise to any common law or statutory liability, or otherwise form the basis of any claim, action, suit or proceeding, against the Company or any of the Subsidiaries based on or resulting from the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling, or the emission, discharge or release into the -8-

9 environment, of any pollutant, contaminant or hazardous or toxic material or waste; and (iv) have taken all actions necessary under the Environmental Laws to register any products or materials required to be registered by the Company or any of the Subsidiaries (or any of their respective agents) thereunder. (b) Each of the Selling Shareholders severally represents and warrants to each of the Underwriters as follows: (i) Such Selling Shareholder now has and at the Closing Date (as such dates is hereinafter defined) will have good and marketable title to the Firm Shares to be sold by such Selling Shareholder, free and clear of any liens, encumbrances, equities and claims, and full right, power and authority to effect the sale and delivery of such Firm Shares; and upon the delivery of, against payment for, such Firm Shares pursuant to this Agreement, the Underwriters will acquire good and marketable title thereto, free and clear of any liens, encumbrances, equities and claims. (ii) Such Selling Shareholder has full right, power and authority to execute and deliver this Agreement, the Power of Attorney and the Custodian Agreement referred to below and to perform its obligations under each such agreement. The execution and delivery of this Agreement and the consummation by such Selling Shareholder of the transactions herein contemplated and the fulfillment by such Selling Shareholder of the terms hereof will not require any approval, consent, order, authorization, designation, declaration or filing by or with any court, regulatory administrative or other governmental body (except as may be required by the Commission, the NASD or as may be necessary to qualify the Shares for public offering by the Underwriters under state securities or Blue Sky laws) and will not, with or without the giving of notice or lapse of time or both, result in a violation or breach of any of the terms and provisions of, or constitute a default under, any organizational documents of such Selling Shareholder, if not an individual, or any agreement, lease contract, indenture, mortgage, deed of trust or other instrument or obligation to which such Selling Shareholder is a party, or of any order, rule or regulation applicable to such Selling Shareholder of any court or of any regulatory body or administrative agency or other governmental body having jurisdiction. (iii) Such Selling Shareholder has not taken, directly or indirectly, any action designed to cause or result in, or which has constituted or which might reasonably be expected to cause or result in, the stabilization or manipulation of the price of the Common Stock of the Company. -9-

10 2. PURCHASE, SALE AND DELIVERY OF THE FIRM SHARES. (a) On the basis of the representations, warranties and covenants herein contained, and subject to the conditions herein set forth, the Sellers agree to sell to the Underwriters and each Underwriter agrees, severally and not jointly, to purchase, at a price of $_____ [net price] per share, the number of Firm Shares set forth opposite the name of each Underwriter in Schedule I hereof, subject to adjustments in accordance with Section 9 hereof. The number of Firm Shares to be purchased by each Underwriter from each Seller shall be as nearly as practicable in the same proportion to the total number of Firm Shares being sold by each Seller as the number of Firm Shares being purchased by each Underwriter bears to the total number of Firm Shares to be sold hereunder. The obligations of the Company and of each of the Selling Shareholders shall be several and not joint. (b) Certificates in negotiable form for the total number of the Shares to be sold hereunder by the Selling Shareholders have been placed in custody with Bryan Cave L.L.P. as custodian (the "Custodian") pursuant to the Custodian Agreement executed by each Selling Shareholder for delivery of all Firm Shares to be sold hereunder by the Selling Shareholders. Each of the Selling Shareholders specifically agrees that the Firm Shares represented by the certificates held in custody for the Selling Shareholders under the Custodian Agreement are subject to the interests of the Underwriters hereunder, that the arrangements made by the Selling Shareholders for such custody are to that extent irrevocable, and that the obligations of the Selling Shareholders hereunder shall not be terminable by any act or deed of the Selling Shareholders (or by any other person, firm or corporation including the Company, the Custodian or the Underwriters) or by operation of law (including the death of an individual Selling Shareholder or the dissolution of a Selling Shareholder that is a corporation, partnership or other entity) or by the occurrence of any other event or events, except as set forth in the Custodian Agreement. If any such event should occur prior to the delivery to the Underwriters of the Firm Shares hereunder, certificates for the Firm Shares shall be delivered by the Custodian in accordance with the terms and conditions of this Agreement as if such event has not occurred. The Custodian is authorized to receive and acknowledge receipt of the proceeds of sale of the Shares held by it against delivery of such Shares. (c) Payment for the Firm Shares to be sold hereunder is to be made in same day funds via wire transfer to the order of the Company for the shares to be sold by it and to the order of Bryan Cave L.L.P., "as Custodian" for the shares to be sold by the Selling Shareholders, in each case against delivery of certificates therefor to the Representatives for the several accounts of the Underwriters. Such payment and delivery are to be made at the offices of BT Alex. Brown Incorporated, 1 South Street, Baltimore, Maryland, at 10:00 a.m., Baltimore time, on the third business day after the date of this Agreement or at such other time and date not later than five business days thereafter as you and the Company shall agree upon, such time and date being herein referred to as the "Closing Date." (As used herein, "business day" means a day on which -10-

11 the New York Stock Exchange is open for trading and on which banks in New York are open for business and not permitted by law or executive order to be closed.) The certificates for the Firm Shares will be delivered in such denominations and in such registrations as the Representatives request in writing not later than the second full business day prior to the Closing Date, and will be made available for inspection by the Representatives at least one business day prior to the Closing Date. (d) In addition, on the basis of the representations, warranties and covenants herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the several Underwriters to purchase the Option Shares at the price per share as set forth in the first paragraph of this Section 2. The option granted hereby may be exercised in whole or in part by giving written notice (i) at any time before the Closing Date and (ii) only once thereafter within 30 days after the date of this Agreement, by you, as Representatives of the several Underwriters, to the Company, setting forth the number of Option Shares as to which the several Underwriters are exercising the option, the names and denominations in which the Option Shares are to be registered and the time and date at which such certificates are to be delivered. The time and date at which certificates for Option Shares are to be delivered shall be determined by the Representatives but shall not be earlier than three nor later than 10 full business days after the exercise of such option, nor in any event prior to the Closing Date (such time and date being herein referred to as the "Option Closing Date"). If the date of exercise of the option is three or more days before the Closing Date, the notice of exercise shall set the Closing Date as the Option Closing Date. The number of Option Shares to be purchased by each Underwriter shall be in the same proportion to the total number of Option Shares being purchased as the number of Firm Shares being purchased by such Underwriter bears to the total number of Firm Shares, adjusted by you in such manner as to avoid fractional shares. The option with respect to the Option Shares granted hereunder may be exercised only to cover over-allotments in the sale of the Firm Shares by the Underwriters. You, as Representatives of the several Underwriters, may cancel such option at any time prior to its expiration by giving written notice of such cancellation to the Company to the Representatives for the several accounts of the Underwriters. Such payment and delivery are to be made. To the extent, if any, that the option is exercised, payment for the Option Shares shall be made on the Option Closing Date in same day funds via wire transfer to the order of the Company against delivery of certificates therefor to the Representatives for the several accounts of the Underwriters. Such payment and delivery are to be made at the offices of BT Alex. Brown Incorporated, 1 South Street, Baltimore, Maryland on the Option Closing Date. (e) If on the Closing Date any Selling Shareholder fails to sell the Firm Shares which such Selling Shareholder has agreed to sell on such date as set forth in Schedule II hereto, the Company agrees that it will sell or arrange for the sale of that number of shares of Common Stock to the Underwriters which represents Firm Shares which such Selling Shareholder has failed to so sell, as set forth in Schedule II hereto, or such lesser number as may be requested by the Representatives. -11-

12 3. OFFERING BY THE UNDERWRITERS. It is understood that the several Underwriters are to make a public offering of the Firm Shares as soon as the Representatives deem it advisable to do so. The Firm Shares are to be initially offered to the public at the public offering price set forth in the Prospectus. The Representatives may from time to time thereafter change the public offering price and other selling terms. To the extent, if at all, that any Option Shares are purchased pursuant to Section 2 hereof, the Underwriters will offer them to the public on the foregoing terms. It is further understood that you will act as the Representatives for the Underwriters in the offering and sale of the Shares in accordance with a Master Agreement Among Underwriters entered into by you and the several other Underwriters. 4. COVENANTS OF THE COMPANY AND THE SELLING SHAREHOLDERS. (a) The Company covenants and agrees with each of the several Underwriters that: (i) The Company will (A) use its best efforts to cause the Registration Statement to become effective or, if the procedure in Rule 430A of the Rules and Regulations is followed, to prepare and timely file with the Commission under Rule 424(b) of the Rules and Regulations a Prospectus in a form approved by the Representatives containing information previously omitted at the time of effectiveness of the Registration Statement in reliance on Rule 430A of the Rules and Regulations, and (B) not file any amendment to the Registration Statement or any amendment or supplement to the Prospectus or document incorporated by reference therein of which the Representatives shall not previously have been advised and furnished with a copy or to which the Representatives shall have reasonably objected in writing or which is not in compliance with the Rules and Regulations and (C) file on a timely basis all reports and any definitive proxy or information statements required to be filed by the Company with the Commission subsequent to the date of the Prospectus and prior to the termination of the offering of the Shares by the Underwriters. (ii) The Company will advise the Representatives promptly (A) when the Registration Statement or any post-effective amendment thereto shall have become effective, (B) of receipt of any comments from the Commission, (C) of any request of the Commission for amendment of the Registration Statement or for supplement to the Prospectus or for any additional information, and (D) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the use of the Prospectus or of the institution of any proceedings for that purpose. The Company will use its best efforts to prevent the issuance of any such stop order or proceeding and to obtain as soon as possible the lifting thereof, if issued. (iii) The Company will cooperate with the Representatives in endeavoring to qualify the Shares for sale under the securities laws of such jurisdictions as the Representatives may -12-

13 reasonably have designated in writing and will make such applications, file such documents, and furnish such information as may be reasonably required for that purpose, provided the Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent. The Company will, from time to time, prepare and file such statements, reports, and other documents, as are or may be required to continue such qualifications in effect for so long a period as the Representatives may reasonably request for distribution of the Shares. (iv) The Company will deliver to, or upon the order of, the Representatives, from time to time, as many copies of any Preliminary Prospectus as the Representatives may reasonably request. The Company will deliver to, or upon the order of, the Representatives during the period when delivery of a Prospectus is required under the Act, as many copies of the Prospectus in final form, or as thereafter amended or supplemented, as the Representatives may reasonably request. The Company will deliver to the Representatives at or before the Closing Date, four signed copies of the Registration Statement and all amendments thereto including all exhibits filed therewith, and will deliver to the Representatives such number of copies of the Registration Statement (including such number of copies of the exhibits filed therewith that may reasonably be requested), including documents incorporated by reference therein, and of all amendments thereto, as the Representatives may reasonably request. (v) The Company will comply with the Act and the Exchange Act and the Rules and Regulations so as to permit the completion of the distribution of the Shares as contemplated in this Agreement and the Prospectus. If during the period in which a prospectus is required by law to be delivered by an Underwriter or dealer, any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Underwriters, it becomes necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances existing at the time the Prospectus is delivered to a purchaser, not misleading, or, if it is necessary at any time to amend or supplement the Prospectus to comply with any law, the Company promptly will either (i) prepare and file with the Commission an appropriate amendment to the Registration Statement or supplement to the Prospectus or (ii) prepare and file with the Commission an appropriate filing under the Exchange Act which shall be incorporated by reference in the Prospectus so that the Prospectus as so amended or supplemented will not, in the light of the circumstances when it is so delivered, be misleading, or so that the Prospectus will comply with the law. (vi) The Company will make generally available to its security holders, as soon as it is practicable to do so, but in any event not later than 15 months after the effective date of the Registration Statement, an earnings statement (which need not be audited) in reasonable detail, covering a period of at least 12 consecutive months beginning after the effective date of the Registration Statement, which earnings statement shall satisfy the requirements of Section 11(a) -13-

14 of the Act and Rule 158 of the Rules and Regulations and will advise you in writing when such earnings statement has been so made available. (vii) The Company will, for a period of five years from the Closing Date, deliver to the Representatives copies of annual reports and copies of all other documents, reports and information furnished by the Company to its stockholders or filed with any securities exchange on The Nasdaq Stock Market pursuant to the requirements of such exchange or The Nasdaq Stock Market or with the Commission pursuant to the Act or the Exchange Act. The Company will deliver to the Representatives similar reports with respect to significant subsidiaries, as that term is defined in the Rules and Regulations, which are not consolidated in the Financial Statements. (viii) No offering, sale, short sale, pledge or other disposition of any shares of Common Stock of the Company or other capital stock of the Company, or other securities convertible into or exchangeable or exercisable for shares of Common Stock or derivatives of Common Stock of the Company (or entering into agreements for such) will be made for a period of 360 days after the date of this Agreement, directly or indirectly, by the Company otherwise than hereunder except (A) that the Company may issue, and grant options or warrants to purchase, shares of Common Stock of the Company or any shares convertible into, exercisable for or exchangeable for shares of Common Stock of the Company, upon the exercise of outstanding options and warrants and its issuance of options and stock granted under the existing stock option plan, (B) in connection with acquisition transactions, or (C) with the prior written consent of BT Alex. Brown Incorporated. (ix) The Company will use its best efforts to promptly list, subject to notice of issuance, the Shares on the Nasdaq National Market. (x) The Company has caused each executive officer and director of the Company to furnish to you, on or prior to the date of this Agreement, a letter or letters, in form and substance satisfactory to the Underwriters ("Lockup Agreements"), pursuant to which each such person has agreed not to offer, sell, sell short, pledge or otherwise dispose of any shares of Common Stock of the Company or other capital stock of the Company, or any other securities convertible, exchangeable or exercisable for shares of Common Stock of the Company or derivatives of Common Stock of the Company (or enter into agreements for such) owned by such person or request the registration for the offer or sale of any of the foregoing (or as to which such person has the right to direct the disposition of) for a period of 360 days after the date of this Agreement, directly or indirectly, except (A) as otherwise provided in the Lockup Agreements or (B) with the prior written consent of BT Alex. Brown Incorporated. (xi) The Company shall apply the net proceeds of its sale of the Shares as set forth in the Prospectus. -14-

15 (xii) The Company shall not invest, or otherwise use the proceeds received by the Company from its sale of the Shares in such a manner as would require the Company or any of the Subsidiaries to register as an "investment company" within the meaning of such term under the 1940 Act and the Rules and Regulations. (xiii) The Company will maintain a transfer agent and, if necessary under the laws of the State of Delaware, a registrar for the Common Stock. (xiv) The Company will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, the stabilization or manipulation of the price of the Common Stock of the Company. (b) Each of the Selling Shareholders severally covenants and agrees with each of the several Underwriters that: (i) No offering, sale, short sale, pledge or other disposition of any shares of Common Stock of the Company or other capital stock of the Company or other securities convertible, exchangeable or exercisable for Common Stock or derivatives of Common Stock (or entering into any agreement for such) owned by the Selling Shareholder or request the registration for the offer or sale of any of the foregoing (or as to which the Selling Shareholder has the right to direct the disposition of) will be made for a period of 360 days after the date of this Agreement, directly or indirectly, by such Selling Shareholder otherwise than hereunder, except (A) as otherwise provided in the Lockup Agreement by and between you and Selling Shareholder or (B) with the prior written consent of BT Alex. Brown Incorporated. (ii) In order to document the Underwriters' compliance with the reporting and withholding provisions of the Tax Equity and Fiscal Responsibility Act of 1982 and the Interest and Dividend Tax Compliance Act of 1983 with respect to the transactions herein contemplated, each of the Selling Shareholders agrees to deliver to you prior to or at the Closing Date a properly completed and executed United States Treasury Department Form W-9 (or other applicable form or statement specified by Treasury Department regulations in lieu thereof). (iii) Such Selling Shareholder will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, the stabilization or manipulation of the price of the Common Stock of the Company. Other than as permitted by the Act, the Selling Shareholder will not distribute any prospectus or other offering materials in connection with the offering of the Shares. 5. COSTS AND EXPENSES. The Company will pay all costs, expenses and fees incident to the performance of the obligations of the Sellers under this Agreement, including, without limiting the generality of the -15-

16 foregoing, the following: accounting fees of the Company; the fees and disbursements of counsel for the Company and the Selling Shareholders; the cost of printing and delivering to, or as requested by, the Underwriters copies of the Registration Statement, Preliminary Prospectuses, the Prospectus, this Agreement; the filing fees of the Commission; the filing fee of the NASD; and the Listing Fee of the Nasdaq National Market. [The Selling Shareholders have agreed with the Company to reimburse the Company for a portion of such expenses. To the extent, if at all, that any of the Selling Shareholders engage special legal counsel to represent them in connection with this offering, the fees and expenses of such counsel shall be borne solely by such Selling Shareholder. Any transfer taxes imposed on the sale of the Shares to the several Underwriters will be paid by the Sellers pro rata.] The Sellers shall not, however, be required to pay for any of the Underwriters' expenses (other than those related to qualification under NASD regulation) except that, if this Agreement shall not be consummated because the conditions in Section 6 hereof are not satisfied, or because this Agreement is terminated by the Representatives pursuant to Section 11 hereof, or by reason of any failure, refusal or inability on the part of the Company or the Selling Shareholders to perform any undertaking or satisfy any condition of this Agreement or to comply with any of the terms hereof on their part to be performed, unless such failure to satisfy said condition or to comply with said terms be due to the default or omission of any Underwriter, then the Company shall reimburse the several Underwriters for reasonable out-of-pocket expenses, including fees and disbursements of counsel, reasonably incurred in connection with investigating, marketing and proposing to market the Shares or in contemplation of performing their obligations hereunder; but the Company and the Selling Shareholders shall not in any event be liable to any of the Underwriters for damages on account of loss of anticipated profits from the sale by them of the Shares. 6. CONDITIONS OF OBLIGATIONS OF THE UNDERWRITERS. The several obligations of the Underwriters to purchase the Firm Shares on the Closing Date and the Option Shares, if any, on the Option Closing Date are subject to the accuracy, as of the Closing Date or the Option Closing Date, as the case may be, of the representations and warranties of the Company and the Selling Shareholders contained herein, and to the performance by the Company and the Selling Shareholders of their covenants and obligations hereunder and to the following additional conditions: -16-

17 (a) The Registration Statement and all post-effective amendments thereto shall have become effective and any and all filings required by Rule 424 and Rule 430A of the Rules and Regulations shall have been made, and any request of the Commission for additional information (to be included in the Registration Statement or otherwise) shall have been disclosed to the Representatives and complied with to their reasonable satisfaction. No stop order suspending the effectiveness of the Registration Statement, as amended from time to time, shall have been issued and no proceedings for that purpose shall have been taken or, to the knowledge of the Company or the Selling Shareholders, shall be contemplated by the Commission and no injunction, restraining order, or order of any nature by a Federal or state court of competent jurisdiction shall have been issued as of the Closing Date which would prevent the issuance of the Shares. (b) The Representatives shall have received on the Closing Date or the Option Closing Date, as the case may be, the opinion[s] of Bryan Cave L.L.P., counsel for the Company [and the Selling Shareholders], dated the Closing Date or the Option Closing Date, as the case may be, addressed to the Underwriters (and stating that it may be relied upon by counsel to the Underwriters) to the effect that: (i) The Company has been duly organized and is validly existing as a corporation in good standing under the laws of the State of Delaware, with corporate power and authority to own or lease its properties and conduct its business as described in the Registration Statement. Each of the Subsidiaries has been duly organized and is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation, with corporate power and authority to own or lease its properties and conduct its business as described in the Registration Statement. The Company and each of the Subsidiaries are duly qualified to transact business in all jurisdictions in which the conduct of their business requires such qualification. The outstanding shares of capital stock of each of the Subsidiaries have been duly authorized and validly issued, are fully paid and non-assessable and are owned by the Company or another Subsidiary. To the best of such counsel's knowledge except as set forth on Schedule III hereto, the outstanding shares of capital stock of each of the Subsidiaries is owned free and clear of all liens, encumbrances, equities and claims, and no options, warrants or other rights to purchase, agreements or other obligations to issue or other rights to convert any obligations into any shares of capital stock or ownership interests in the Subsidiaries are outstanding. (ii) The Company has authorized and outstanding capital stock as set forth under the caption "Capitalization" in the Prospectus. The outstanding shares of Common Stock of the Company, including the Shares to be sold by the Selling Shareholders, have been duly authorized and validly issued and are fully paid and non-assessable; all of the Shares conform to the description thereof contained in the Prospectus; the certificates for the Shares, assuming they are in the form filed with the Commission, are in due and proper form. The Shares to be issued and sold by the Company have been duly authorized and when issued and paid for as contemplated -17-

18 by this Agreement will be validly issued, fully paid and non-assessable; and no preemptive rights of stockholders exist with respect to any of the Shares or the issue or sale thereof. (iii) Except as described in or contemplated by the Prospectus, to the best of such counsel' knowledge, there are no outstanding securities of the Company convertible or exchangeable into or evidencing the right to purchase or subscribe for any shares of capital stock of the Company and there are no outstanding or authorized options, warrants or rights of any character obligating the Company to issue any shares of its capital stock or any securities convertible or exchangeable into or evidencing the right to purchase or subscribe for any shares of such stock. To the best of such counsel's knowledge, no holder of any securities of the Company or any other person has the right, contractual or otherwise, which has not been satisfied or effectively waived, to cause the Company to sell or otherwise issue to them, or to permit them to underwrite the sale of, any of the Shares or the right to have any shares of Common Stock or other securities of the Company included in the Registration Statement or the right, as a result of the filing of the Registration Statement, to require registration under the Act of any shares of Common Stock or other securities of the Company. (iv) The Registration Statement has become effective under the Act. To the best of such counsel's knowledge, the Commission has not issued an order preventing or suspending the use of any Prospectus relating to the proposed offering of the Shares nor are any proceedings for that purpose pending or threatened. (v) The Registration Statement, and each amendment thereto, and the Prospectus, and each amendment or supplement thereto, comply as to form in all material respects with the requirements of the Act or the Exchange Act, as applicable, and the Rules and Regulations (except that such counsel need express no opinion as to the Financial Statements). The conditions for the use of Form S-2, set forth in the General Instructions thereto, have been satisfied. (vi) The statements under the caption "Description of Common Stock and Other Securities" in the Prospectus, insofar as such statements constitute a summary of documents referred to therein or matters of law, fairly summarize in all material respects the information called for with respect to such documents and matters. (vii) Such counsel does not know of any contracts or documents required to be filed as exhibits to or incorporated by reference in the Registration Statement or described in the Registration Statement or the Prospectus which are no so filed, incorporated by reference or described as required, and such contracts and documents that are summarized in the Registration Statement or the Prospectus are fairly summarized in all material respects. -18-

19 (viii) To the best of such counsel's knowledge, there is no action, suit, claim or proceeding pending or threatened against the Company or any of the Subsidiaries before any court or administrative agency or otherwise which if determined adversely to the Company or any of the Subsidiaries might result in any material adverse change in the earnings, business, management, properties, assets, rights, operations, condition (financial or otherwise) or prospects of the Company and of the Subsidiaries taken as a whole, whether or not arising in the ordinary course of business, or prevent the consummation of the transactions contemplated hereby. (ix) The execution and delivery of this Agreement and the consummation of the transactions herein contemplated and the fulfillment of the terms hereof will not, with or without the giving of notice or lapse of time or both, conflict with or result in a violation or breach of any of the terms or provisions of, or constitute a default under, any agreement, lease, contract, indenture, mortgage, deed of trust or other instrument or obligation to which the Company or any of the Subsidiaries is a party, or of the Certificate or Incorporation or By-Laws of the Company or any order, rule or regulation applicable to the Company or any of the Subsidiaries of any court or of any regulatory body or administrative agency or other governmental body having jurisdiction. (x) This Agreement has been duly authorized, executed and delivered by the Company. (xi) No approval, consent, order, authorization, designation, declaration or filing by or with any regulatory, administrative or other governmental body is necessary in connection with the execution and delivery of this Agreement by the Company and the Selling Shareholders and the consummation of the transactions herein contemplated and the fulfillment by the Company and the Selling Shareholders of the terms hereof (other than as may be required by the Commission, the NASD or as may be necessary to qualify the Shares for public offering by the Underwriters under state securities or Blue Sky laws as to which such counsel need express no opinion) except such as have been obtained or made, specifying the same. (xii) Neither the Company nor any of the Subsidiaries will or will not become, as a result of the consummation of the transactions contemplated by this Agreement and application of the net proceeds therefrom as described in the Prospectus, an "investment company" within the meaning of such term under the 1940 Act and the Rules and Regulations. (xiii) This Agreement has been duly authorized, executed and delivered by or on behalf of the Selling Shareholders. (xiv) Each Selling Shareholder has full legal right, power and authority, and any approval required by law (other than as required by State securities and Blue Sky laws as to which such counsel need express no opinion), to sell, assign, transfer and deliver the portion of the Shares to be sold by such Selling Shareholder. -19-

20 (xv) The Custodian Agreement and the Power of Attorney executed and delivered by each Selling Shareholder is valid and binding. (xvi) The Underwriters (assuming that they are bona fide purchasers within the meaning of the Uniform Commercial Code) have acquired good and marketable title to the Shares being sold by each Selling Shareholder on the Closing Date, free and clear of all liens, encumbrances, equities and claims. In rendering such opinion Bryan Cave L.L.P. may rely as to matters governed by the laws of states other than Arizona and Delaware or Federal laws on local counsel in such jurisdictions [and as to the matters set forth in subparagraphs (xiii), (xiv) and (xv) on opinions of other counsel representing the respective Selling Shareholders], provided that in each case Bryan Cave L.L.P. shall state that they believe that they and the Underwriters are justified in relying on such other counsel. In addition to the matters set forth above, such opinion shall also include a statement to the effect that nothing has come to the attention of such counsel which leads them to believe that (i) the Registration Statement, or any amendment thereto, at the time the Registration Statement became effective under the Act (but after giving effect to any modifications incorporated therein pursuant to Rule 430A under the Act) and as of the Closing Date or the Option Closing Date, as the case may be, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading (except that such counsel need express no view as to Financial Statements), and (ii) the Prospectus, or any amendment or supplement thereto, on the date it was filed and as of the Closing Date or the Option Closing Date, as the case may be, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading (except that such counsel need express no view as to Financial Statements). With respect to such statement, Bryan Cave L.L.P. may state that their belief is based upon the procedures set forth therein, but is without independent check and verification. (c) The Representatives shall have received from Piper & Marbury L.L.P., counsel for the Underwriters, an opinion dated the Closing Date or the Option Closing Date, as the case may be, substantially to the effect specified in subparagraphs (ii), (iii), (iv), (x) and (xiii) of Paragraph (b) of this Section 6. In rendering such opinion, Piper & Marbury L.L.P. may rely as to all matters governed other than by the laws of the State of Maryland or Federal laws on the opinion of counsel referred to in Paragraph (b) of this Section 6. In addition to the matters set forth above, such opinion shall also include a statement to the effect that nothing has come to the attention of such counsel which leads them to believe that (i) the Registration Statement, or any amendment thereto, at the time the Registration Statement became effective under the Act (but after giving effect to any modifications incorporated therein pursuant to Rule 430A under the Act) and as of the Closing Date or the Option Closing Date, as the case may be, contained an -20-

21 untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements, in the light of the circumstances under which they are made, not misleading (except that such counsel need express no view as to Financial Statements), and (ii) the Prospectus, or any amendment or supplement thereto, on the date it was filed and as of the Closing Date or the Option Closing Date, as the case may be, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements, in the light of the circumstances under which they are made, not misleading (except that such counsel need express no view as to Financial Statements). With respect to such statement, Piper & Marbury L.L.P. may state that their belief is based upon the procedures set forth therein, but is without independent check and verification. (d) You shall have received, on each of the dates hereof, the Closing Date and the Option Closing Date, as the case may be, a letter dated the date hereof, the Closing Date or the Option Closing Date, as the case may be, in form and substance satisfactory to you, of Arthur Andersen LLP confirming that they are independent public accountants within the meaning of the Act and the Rules and Regulations and stating that in their opinion the Financial Statements comply in all material respects with the applicable accounting requirements of the Act and the Rules and Regulations; and containing such other statements and information as is ordinarily included in accountants' "comfort letters" to Underwriters with respect to the Financial Statements and certain financial and statistical information contained or incorporated by reference in the Registration Statement and Prospectus. (e) The Representatives shall have received on the Closing Date or the Option Closing Date, as the case may be, a certificate or certificates of the Chief Executive Officer and the Chief Financial Officer of the Company to the effect that, as of the Closing Date or the Option Closing Date, as the case may be, each of them severally represents as follows: (i) The Registration Statement has become effective under the Act. To the best of his knowledge, the Commission has not issued an order preventing or suspending the use of any Prospectus relating to the proposed offering of the Shares nor are any proceedings for that purpose pending or threatened. (ii) The representations and warranties of the Company contained in Section 1(a) hereof are true and correct as of the Closing Date or the Option Closing Date, as the case may be; (iii) All filings required to have been made pursuant to Rules 424 or 430A under the Act have been made; (iv) He has carefully examined the Registration Statement and the Prospectus and, in his or her opinion, as of the effective date of the Registration Statement, the statements contained in the Registration Statement were true and correct, and such Registration Statement -21-

22 and Prospectus did not omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading, and since the effective date of the Registration Statement, no event has occurred which should have been set forth in a supplement or amendment of the Registration Statement or the Prospectus which has not been so set forth in such supplement or amendment; and (v) Since the respective dates as of which information is given in the Registration Statement and Prospectus, there has not been any material adverse change or any development involving a prospective material adverse change in or affecting the condition, financial or otherwise, of the Company and the Subsidiaries taken as a whole or the earnings, business, management, properties, assets, rights, operations, condition (financial or otherwise) or prospects of the Company and the Subsidiaries taken as a whole, whether or not arising in the ordinary course of business. (f) The Company and the Selling Shareholders shall have furnished to the Representatives such further certificates and documents confirming the representations and warranties, covenants and conditions contained herein and related matters as the Representatives may reasonably have requested. (g) The Firm Shares and Option Shares, if any, have been approved for designation upon notice of issuance on the Nasdaq National Market. (h) The Lockup Agreements described in Sections 4(a)(viii), 4(x) and 4(b)(i) are in full force and effect. The opinions and certificates mentioned in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in all material respects satisfactory to the Representatives and to Piper & Marbury L.L.P., counsel for the Underwriters. If any of the conditions hereinabove provided for in this Section 6 shall not have been fulfilled when and as required by this Agreement to be fulfilled, the obligations of the Underwriters hereunder may be terminated by the Representatives by notifying the Company and the Selling Shareholders of such termination in writing or by telegram at or prior to the Closing Date or the Option Closing Date, as the case may be. In such event, the Selling Shareholders, the Company and the Underwriters shall not be under any obligation to each other (except to the extent provided in Sections 5 and 8 hereof). 7. CONDITIONS OF THE OBLIGATIONS OF THE SELLERS. The obligations of the Sellers to sell and deliver the portion of the Shares required to be delivered as and when specified in this Agreement are subject to the conditions that at the -22-

23 Closing Date or the Option Closing Date, as the case may be, no stop order suspending the effectiveness of the Registration Statement shall have been issued and in effect or proceedings therefor initiated or threatened. 8. INDEMNIFICATION. (a) The Company and the Selling Shareholders, jointly and severally, agree to indemnify and hold harmless each Underwriter and each person, if any, who controls of any Underwriter within the meaning of the Act, against any losses, claims, damages or liabilities to which such Underwriter or any such controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, or any amendment thereto, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made; and will reimburse each Underwriter and each such controlling person upon demand for any legal or other expenses reasonably incurred by such Underwriter or such controlling person in connection with investigating or defending any such loss, claim, damage or liability, action or proceeding or in responding to a subpoena or governmental inquiry related to the offering of the Shares, whether or not such Underwriter or controlling person is a party to any action or proceeding; provided, however, that the Company and the Selling Shareholders will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement, or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Prospectus, or such amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or through the Representatives specifically for use in the preparation thereof. In no event, however, shall the aggregate liability of any Selling Shareholder for indemnification under this Section 8(a) exceed the lesser of (i) that proportion of the total of such losses, claims, damages or liabilities indemnified against equal to the proportion of the total Shares sold hereunder which is being sold by such Selling Shareholder, or (ii) the net proceeds after underwriters discounts and commissions received by such Selling Shareholder from the Underwriters in the offering. This indemnity agreement will be in addition to any liability which the Company or the Selling Shareholders may otherwise have. (b) Each Underwriter severally and not jointly will indemnify and hold harmless the Company, each of its directors, each of its officers who have signed the Registration Statement, the Selling Shareholders, and each person, if any, who controls the Company or the Selling Shareholders within the meaning of the Act, against any losses, claims, damages or liabilities to which the Company or any such director, officer, Selling Shareholder or controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities -23-

24 (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, or (ii) the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made; and will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, Selling Shareholder or controlling person in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding; provided, however, that each Underwriter will be liable in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, any Preliminary Prospectus, the Prospectus or such amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or through the Representatives specifically for use in the preparation thereof. This indemnity agreement will be in addition to any liability which such Underwriter may otherwise have. (c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section 8, such person (the "indemnified party") shall promptly notify the person against whom such indemnity may be sought (the "indemnifying party") in writing. No indemnification provided for in Section 8(a) or (b) shall be available to any party who shall fail to give notice as provided in this Section 8(c) if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability which it or they may have to the indemnified party for contribution or otherwise than on account of the provisions of Section 8(a) or (b). In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party and shall pay as incurred the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel at its own expense. Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the fees and expenses of the counsel retained by the indemnified party in the event (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party shall have failed to assume the defense and employ counsel acceptable to the indemnified party within a reasonable period of time after notice of commencement of the action. It is understood that the -24-

25 indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm for all such indemnified parties. Such firm shall be designated in writing by you in the case of parties indemnified pursuant to Section 8(a) and by the Company in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. In addition, the indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding. (d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to indemnify and hold harmless an indemnified party under Section 8(a) or (b) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Shareholders on the one hand and the Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Selling Shareholders on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Shareholders on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Selling Shareholders bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Selling Shareholders on the one hand or the Underwriters on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. -25-

26 The Company, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Section 8(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), (i) no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Shares purchased by such Underwriter, (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation, and (iii) no Selling Shareholder shall be required to contribute any amount in excess of the lesser of (A) that proportion of the total of such losses, claims, damages or liabilities indemnified or contributed against equal to the proportion of the total Shares sold hereunder which is being sold by such Selling Shareholder, or (B) the net proceeds after underwriters discounts and commissions received by such Selling Shareholder from the Underwriters in the offering. The Underwriters' obligations in this Section 8(d) to contribute are several in proportion to their respective underwriting obligations and not joint. (e) In any action, claim or proceeding relating to the Registration Statement, any Preliminary Prospectus, the Prospectus or any supplement or amendment thereto, each party against whom contribution may be sought under this Section 8 hereby consents to the jurisdiction of any court having jurisdiction over any other contributing party, agrees that process issuing from such court may be served upon him or it by any other contributing party and consents to the service of such process and agrees that any other contributing party may join him or it as an additional defendant in any such proceeding in which such other contributing party is a party. (f) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 8 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section 8 and the representations and warranties of the Company and the Selling Shareholders set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter, the Company, its directors or officers or any persons controlling the Company, (ii) acceptance of any Shares and payment therefor hereunder, and (iii) any termination of this Agreement. A successor to any Underwriter, or any persons controlling any Underwriter, or to the Company shall be entitled to the benefits of the indemnity and contribution contained in this Section 8. -26-

27 9. DEFAULT BY UNDERWRITERS. If on the Closing Date or the Option Closing Date, as the case may be, any Underwriter shall fail to purchase and pay for the portion of the Shares which such Underwriter has agreed to purchase and pay for on such date (otherwise than by reason of any default on the part of the Company or a Selling Shareholder), you, as Representatives of the Underwriters, shall use your reasonable efforts to procure within 36 hours thereafter one or more of the other Underwriters, or any others, to purchase from the Company and the Selling Shareholders such amounts as may be agreed upon and upon the terms set forth herein, the Firm Shares or Option Shares, as the case may be, which the defaulting Underwriter or Underwriters failed to purchase. If during such 36 hours you, as such Representatives, shall not have procured such other Underwriters, or any others, to purchase the Firm Shares or Option Shares, as the case may be, agreed under this Agreement to be purchased by the defaulting Underwriter or Underwriters, then (a) if the aggregate number of Shares with respect to which such default shall occur does not exceed 10% of the Firm Shares or Option Shares, as the case may be, covered hereby, the other Underwriters shall be obligated, severally, in proportion to the respective numbers of Firm Shares or Option Shares, as the case may be, which they are obligated to purchase hereunder, to purchase the Firm Shares or Option Shares, as the case may be, which such defaulting Underwriter or Underwriters failed to purchase, or (b) if the aggregate number of shares of Firm Shares or Option Shares, as the case may be, with respect to which such default shall occur exceeds 10% of the Firm Shares or Option Shares, as the case may be, covered hereby, the Company and the Selling Shareholders or you as the Representatives of the Underwriters will have the right, by written notice given within the next 36-hour period to the parties to this Agreement, to terminate this Agreement without liability on the part of the non-defaulting Underwriters or of the Company or of the Selling Shareholders except to the extent provided in Section 8 hereof. In the event of a default by any Underwriter or Underwriters, as set forth in this Section 9, the Closing Date or Option Closing Date, as the case may be, may be postponed for such period, not exceeding seven days, as you, as Representatives, may determine in order that the required changes in the Registration Statement or in the Prospectus or in any other documents or arrangements may be effected. The term "Underwriter" includes any person substituted for a defaulting Underwriter. Any action taken under this Section 9 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement. 10. NOTICES.

SUCCESSORS. This Agreement has been and is made solely for the benefit of the Underwriters, the Company and the Selling Shareholders and their respective successors, executors, administrators, heirs and assigns, and the officers, directors and controlling persons referred to herein, and no -28-

29 other person will have any right or obligation hereunder. No purchaser of any of the Shares from any Underwriter shall be deemed a successor or assign merely because of such purchase. 13. INFORMATION PROVIDED BY UNDERWRITERS. The Company, the Selling Shareholders and the Underwriters acknowledge and agree that the only information furnished or to be furnished by any Underwriter to the Company for inclusion in any Prospectus or the Registration Statement, or any amendments or supplements thereto, consists of the information set forth in the last paragraph on the front cover page (insofar as such information relates to the Underwriters), legends required by Item 502(d) of Regulation S-K under the Act and the information in all but the last paragraph under the caption "Plan of Distribution" in the Prospectus. 14.

This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

1 OPINION OF BRYAN CAVE LLP EXHIBIT 5.1 BRYAN CAVE LLP TWO NORTH CENTRAL AVENUE SUITE 2200 PHOENIX, ARIZONA 85004 April 12, 1999 Mobile Mini, Inc. 1834 West Third Street Tempe, Arizona 85281 Dear Sirs: We are acting as counsel to Mobile Mini, Inc. (the "Company") in connection with the Registration Statement on Form S-2 (the "Registration Statement"), under the Securities Act of 1933, as amended (the "Act"), covering 2,500,000 shares (the "Company Shares") of the Company's common stock, par value $.01 per share (the "Common Stock") to be sold by the Company and 600,000 shares of Common Stock (the "Selling Stockholder Shares") to be sold by the Selling Stockholders identified in the Registration Statement. We have examined the originals, or certified, conformed or reproduction copies, of all such records, agreements, instruments and documents as we have deemed relevant or necessary as the basis for the opinion hereinafter expressed. In all such examinations, we have assumed the genuineness of all signatures on original or certified copies and the conformity to original or certified copies of all copies submitted to us as conformed or reproduction copies. As to various questions of fact relevant to such opinion, we have relied upon, and assumed the accuracy of, certificates and oral or written statements and other information of or from public officials, officers or representatives of the Company, and others. Based upon the foregoing, we are of the opinion that (i) the Selling Stockholder Shares which are outstanding on the date hereof are validly issued, fully paid and non-assessable shares of Common Stock and the Selling Stockholder Shares which will be issued pursuant to the terms of outstanding warrants will be, when so issued, be validly issued, fully paid and non-assessable shares of Common Stock, and (ii) when the Registration Statement has become effective under the Act and the Company Shares have been issued, sold and paid for in the manner described in the Registration Statement, the Company Shares will be validly issued, fully paid and non-assessable shares of Common Stock. We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to this firm under the caption "Validity of the Shares" in the Prospectus forming a part of the Registration Statement. In giving this consent, we do not hereby admit that we are in the category of persons whose consent is required under Section 7 of the Act. Very truly yours, /s/ BRYAN CAVE LLP
