This Annual Report contains  forward-looking  statements which involve risks and
uncertainties.  The  actual  results of Mobile  Mini,  Inc.  (together  with its
wholly-owned  subsidiaries,   the  "Company"  or  "Mobile  Mini")  could  differ
materially  from those  anticipated  in these  forward-looking  statements  as a
result of certain  factors,  including those set forth in this Form 10-K and the
Company's other  Securities and Exchange  Commission  filings.  See particularly
Item 7, "Management's Discussion and Analysis of Financial Condition and Results
of Operations - Factors That May Affect Future Operating Results".

ITEM 1.  DESCRIPTION OF BUSINESS.

General

Mobile Mini, Inc. is a Delaware corporation  capitalized  effective December 31,
1993.  From 1983  through  1993,  the  business  operations  of the Company were
conducted  as a sole  proprietorship  by Richard E. Bunger  under the  tradename
"mobile mini storage systems" ("MMSS").  The business operations  transferred to
the Company were comprised of MMSS and a related  corporation,  Delivery  Design
Systems,  Inc. ("DDS").  The Company's  subsidiaries  include DDS which formerly
engaged  in the  business  of  designing,  developing  and  manufacturing  truck
trailers  and  other  delivery  systems  for  the  Company's   portable  storage
containers  and Mobile Mini I, Inc.  which  engages in the business of acquiring
and maintaining certain of the Company's facilities.  The business and assets of
DDS were transferred to the Company in 1996.

The Company's  operations  commenced in Phoenix,  Arizona,  in 1983. By 1986 the
portable  storage concept had been proven and the business was expanded  through
an additional sales and leasing branch established in Tucson,  Arizona. In 1988,
the Company  commenced  operations in Rialto,  California to service the greater
Los  Angeles  area.  In early  1990,  the Company  relocated  its  manufacturing
facility from its original site in Phoenix to a heavy-industry  zoned industrial
park located near Maricopa,  Arizona and administrative offices were established
in Tempe,  Arizona.  In 1994,  the Company  opened a  "satellite"  branch in San
Diego,  California  which is serviced from its Rialto  "hub." Also in 1994,  the
Company  opened  operations  in Texas by the  establishment  of hub locations in
Houston and  Dallas/Fort  Worth.  In early 1995,  the Company  opened  satellite
locations in the San Antonio and Austin metropolitan areas.

During the last few years,  the Company has focused  primarily on expanding  its
leasing  operations,  which provide  higher margins and  profitability  than its
other  operations,  see  "Leasing  Operations".  In January of 1998 the  Company
acquired the assets of Nevada Storage  Containers,  a Las Vegas based  container
leasing and sales business.

Products

The Company designs and manufactures portable steel storage containers, portable
offices and telecommunication shelters and acquires,  refurbishes,  and modifies
ocean-going  shipping  containers for sale and lease as inland portable  storage
units. In addition,  the Company designs and  manufactures a variety of delivery
systems  to  complement  the  Company's  storage  container  sales  and  leasing
activities. The Company has patented,  proprietary or trade secret rights in all
products it has designed and manufactured.  The locking system for the Company's
containers  is patented  and  provides  virtually  impenetrable  security to the
storage container.

The Company's  main product in its storage  market segment is the portable steel
storage container.  The Company acquires used ocean-going cargo containers which
it reconditions  and retrofits with its patented  locking system.  To compensate
for supply and price  fluctuations  associated  with acquiring used  ocean-going
containers,  the Company  also  manufactures  various  lines of new  containers,
featuring the Company's proprietary "W" or "stud wall" panels. Storage container
units may be significantly  modified and turned into portable offices,  portable
storage facilities, open-sided storage and retail facilities, as well as a large
variety of other applications. In reconditioning and manufacturing its products,
the Company  uses,  in addition to used  ocean-going  containers,  commodity raw
materials  including  steel,  vinyl,  wood,  glass and other raw materials  from
various suppliers.

The  Company  leases  and sells its  storage  containers  to a wide  variety  of
individual,  business and  governmental  users.  The Company's lease  activities
include both off-site and on-site  leasing.  "Off-site"  leasing occurs when the
Company  leases  a  portable  storage  container  which is then  located  at the
customer's  place of use.  "On-site"  leasing occurs when the Company stores the
portable 
                                      -2-
<PAGE>
container  containing the customer's  goods at one of the Company's  facilities,
which are  similar  to a  standard  mini-storage  facility,  but with  increased
security, ease of access and container delivery and pick-up service.

In mid-1995,  Mobile Mini  established a  telecommunication  shelter division to
complement its storage container business, diversify its product line and target
the  domestic  and  international   markets.  The  Company's   telecommunication
shelters,  marketed under the name "Mobile  Tele-structures",  can be built in a
vast  variety  of  designs,   sizes,   strengths,   exterior   appearances   and
configurations.  The Company has  developed  proprietary  technology  that makes
these units very  portable,  lightweight,  highly secure and  virtually  weather
resistant.  The Company intends to devote additional  resources toward marketing
this product.

The Company has  developed  technology to add a stucco finish to the exterior of
its  all  steel  buildings,  making  them  more  aesthetically  appealing  while
retaining  the  strength and  durability  afforded by steel.  This  attribute is
especially   important   to  the  Mobile   Tele-structures   operations,   where
telecommunication  companies are under  pressure to use shelters and towers that
blend in with the locale at which they are located.  The Company also introduced
its  ArmorKoat  line of  telecommunication  shelters  which  feature a specially
formulated  concrete  exterior  coat to its  steel  shelters.  This  formulation
increases the strength of the building and can meet the needs of customers  that
require concrete buildings.

The Company designs,  develops and  manufactures a complete  proprietary line of
truck  trailers  and other  delivery  systems  utilized in  connection  with its
storage  container sales and leasing  activities.  The Company provides delivery
and pick-up  services for customers at their places of business,  homes or other
locations.

Business Restructuring

Prior to 1997, the Company was involved in the manufacture,  sale and leasing of
modular  steel  buildings  in the state of Arizona.  These  buildings  were used
primarily  as  portable  schools,  but could be used for a variety of  purposes.
Although  the  Company  believes  its  modular  buildings  were  superior to the
wood-framed  buildings  offered by its competitors,  the Company was not able to
generate  acceptable  margins on this product  line.  During  1996,  the Company
implemented a strategic restructuring program designed to concentrate management
effort and resources and better position itself to achieve its strategic  growth
objectives.  Accordingly, the Company's 1996 results include charges of $700,000
($400,000 after tax, or $.06 per share) for costs associated with  restructuring
the Company's  manufacturing  operations  and for other related  charges.  These
charges were recorded in the fourth  quarter of 1996,  and were comprised of the
write-down  of  assets  used  in the  Company's  discontinued  modular  building
operations and related severance obligations  ($300,000),  and the write-down of
other fixed assets ($400,000). By discontinuing its modular building operations,
the Company is able to utilize the management  resources and production capacity
previously utilized by this division to expand the Company's  telecommunications
shelter business and its container leasing operations.

Marketing

The Company  markets its storage  containers  both  directly to the consumer and
through its national dealer network.  The Company has sales and leasing branches
in Phoenix  and Tucson,  Arizona,  San Diego and  Rialto,  California,  Houston,
Dallas,  San  Antonio  and  Austin,  Texas and Las Vegas,  Nevada.  The  Company
services the greater Los Angeles, California area from its Rialto hub.

The Company sells and leases its storage  containers  directly to consumers from
each of its  branches.  With  respect to  leases,  the  Company  engages in both
off-site  and on-site  leasing.  Marketing  for  individual  consumer  sales and
rentals is  primarily  through  Yellow Page ads,  direct  mailings  and customer
referrals.  The Company markets its Mobile Tele-structures  products directly to
telecommunication   companies,  as  well  as  to  companies  providing  turn-key
installations of shelters and telecommunication towers.

Sales  are also  made  through  the  Company's  national  dealer  network  which
currently  provides  the  Company's  manufactured  containers  to 45 dealers for
retail  sale.  Such  dealers are in 69 separate  locations  in 24 states and two
Canadian  provinces.  Marketing  to dealers and  potential  dealers is primarily
through  direct  solicitation,  trade  shows,  trade  magazine  advertising  and
referrals. The dealers receive pre-fabricated containers which they assemble and
paint. The Company  provides  training in assembly and marketing to its dealers.
None of the dealers are employed by the Company, nor does any dealer have a long
term requirements  contract for the supply of  pre-fabricated  containers or any
contract for training in assembly and  marketing  with the Company.  The Company
does,  however,  benefit  from the use of its  name by  several  dealers  on the
containers once they are constructed.

Leasing Operations
                                      -3-
<PAGE>
Since its founding, it has been the Company's primary goal to grow the container
leasing  portion of its business.  This business,  which involves the short-term
leasing of a product with a long useful life and  relatively  low  depreciation,
offers higher margins than the Company's other products and services.

The Company has sought to grow its container  leasing business by opening branch
facilities in several cities in the Southwestern United States. When the Company
opens  a  facility,  it  devotes  substantial  resources,  including  a  sizable
advertising  budget,  to the  location.  The new locations  therefore  typically
generate  losses in early  years,  but once the  Company  has  added  sufficient
containers to cover the relatively  high fixed costs,  its operations  generally
become   profitable.   Historically,   profitability   is  not  expected   until
approximately  one to three years after the new  location is opened.  The actual
time to profitability  depends upon numerous factors,  including  differences in
container  costs  compared to historic cost levels,  the level of competition in
the new market,  the development of additional  storage containers in the market
by  competitors  and other  factors  which are  generally  beyond the  Company's
control.

The Company plans to continue adding  additional  leased  containers to existing
locations  in order to increase  its  profitability.  During  1996,  the Company
obtained a  revolving  line of credit  enabling it to  substantially  expand its
container leasing operations. Borrowings available under the line of credit were
increased to $40.0 million during 1997.  Additionally,  the Company  completed a
public  offering  during 1997 of 12% Senior  Subordinated  Notes.  See, "ITEM 7.
MANAGEMENT'S  DISCUSSION  AND  ANALYSIS OF  FINANCIAL  CONDITION  AND RESULTS OF
OPERATIONS - LIQUIDITY AND CAPITAL RESOURCES".  The Company increased containers
on lease at December 31, 1997 by 33% from  December 31, 1996.  This increase was
achieved at branch locations that had been in operation at December 31, 1996.

The  Company's  plan is to  continue  increasing  its  lease  fleet at  existing
locations  in  1998.   Management   believes   that  such  an  increase   should
substantially  improve  profitability in 1998,  particularly if the cost of used
ocean-going containers remains constant at year-end 1997 levels.

The Company intends to continue to expand its operations into additional  cities
on a controlled  basis.  Such expansion could be through new start up operations
by the Company or through acquisitions of existing operations. Expansion through
start up  operations  could have the effect of  reducing  net income  during the
early years of operations  while the Company  increases its lease fleet at these
locations.  Management plans to control the number of new start up locations and
their  cost,  in order to  minimize  the effect on current  year  earnings.  The
Company has identified several potential new markets, and is investigating start
up and  acquisition  possibilities  in those markets.  The Company  acquired the
assets of a Las Vegas,  Nevada  based  container  leasing and sales  business in
January 1998, and it is the Company's strategy to review potential  acquisitions
of container leasing businesses or their assets.

Financing

The Company has required  increasing  amounts of financing to support the growth
of its business.  This financing was required  primarily to fund the acquisition
of  containers  for the  Company's  lease fleet and to fund the  acquisition  of
property,  plant and equipment to support both the Company's  container  leasing
and manufacturing operations.

The  Company  finances  its  operations  and growth  primarily  through a credit
agreement (the "Senior Credit  Agreement")  with BT Commercial  Corporation,  as
Agent for a group of lenders  (the  "Lenders").  The  Company  entered  into the
Senior  Credit  Agreement in March 1996, as amended in 1997, in order to improve
its cash  flow,  increase  its  borrowing  availability  and fund its  continued
growth.  Under the terms of the Senior Credit  Agreement,  the Lenders currently
provide the Company with a $40.0 million revolving line of credit and provided a
$6.0 million term loan. Borrowings under the Senior Credit Agreement are secured
by substantially all of the Company's assets.

The term loan is to be repaid over a five-year  period.  Interest accrues on the
term loan at the Company's  option at either prime plus 1.75% or the  Eurodollar
rate plus 3.25%.  Borrowings  under the term loan are payable monthly as follows
(plus interest):

             Months 1   through 12 (April 1996 - March 1997)            $ 62,500
             Months 13 through 24 (April 1997 - March 1998)               83,333
             Months 25 through 60 (April 1998 - March 2001)              118,056
                                      -4-
<PAGE>
Additional  principal  payments  equal to 75% of Excess Cash Flow, as defined in
the term loan documents which  constitute  part of the Senior Credit  Agreement,
are  required  annually.  As of December  31, 1997,  no  additional  payment was
required under this provision.

Available borrowings under the revolving line of credit are based upon the level
of the  Company's  inventories,  receivables  and  container  lease  fleet.  The
container  lease  fleet is  appraised  at least  annually,  and up to 90% of the
lesser of cost or  appraised  orderly  liquidation  value may be included in the
borrowing base.  Interest  accrues at the Company's  option at either prime plus
1.5% or the Eurodollar  rate plus 3% and is payable monthly or at the end of the
term of any Eurodollar  borrowing.  The term of this revolving line of credit is
three years, with a one-year extension option.

In  connection  with the  closing of the Senior  Credit  Agreement,  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,
costs  previously  deferred  related  to  certain  indebtedness  and  prepayment
penalties   resulted  in  an  extraordinary   charge  to  earnings  in  1996  of
approximately $410,000 after benefit for income taxes.

The Senior Credit  Agreement  contains several  financial  covenants and minimum
required  utilization rates in its lease fleet, limits on capital  expenditures,
acquisitions,  changes in control,  the  incurrence of  additional  debt and the
repurchase of common stock, and prohibits the payment of dividends.

The Company has also  financed its  operations  through the issuance and sale of
its equity and debt  securities.  In February  1994,  the Company  completed its
initial public  offering.  Net proceeds to the Company totaled  approximately $7
million.  In December 1995,  the Company  received net proceeds of $4.1 million,
through a private  placement of 50,000 shares of Series A Convertible  Preferred
Stock,  $.01 par value, $100 stated value ("Series A"). Pursuant to the terms of
the Series A, all 50,000 shares of Series A were converted into 1,904,324 shares
of the Company's  common stock at an average  conversion rate of $2.63 per share
during the first quarter of 1996. 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 Mobile Mini,  Inc.  common stock at
$5.00 per share.  The Bridge Notes were due the earlier of July 31, 2002,  or on
the refinancing of the Bridge Notes on  substantially  similar terms. In October
1997, the Company issued $6.9 million of 12% Senior Subordinated Notes ("Notes")
with  redeemable  warrants to purchase  172,500  shares of the Company's  common
stock at $5.00 per share.  The Notes are due November 1, 2002,  and requires the
Company to establish an interest reserve escrow account (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.  Interest is payable  semi-annually on May 1 and November 1 of each
year,  commencing May 1, 1998.  From the proceeds of the sale of the Notes,  the
Company repaid the $3.0 million in Bridge Notes and accrued interest and reduced
the  borrowings  outstanding  under the  revolving  line under the Senior Credit
Agreement  with the  remainder of the net proceeds.  The warrants  issued to the
Bridge Note lender were canceled, in exchange for 15,000 shares of common stock.
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.
These equity and debt issuances provided  additional capital in conjunction with
obtaining the financing available under the Senior Credit Agreement. In February
1998,  the  Company  realized  proceeds  of  approximately  $5.2  million on the
exercise of warrants  issued in connection  with its initial public  offering in
1994.

Patents, Tradenames and Trade Secrets

The Company has eight patents  issued by and four patents  pending with the U.S.
Patent  and  Trademark  Office  related to the  design  and  application  of its
products.  The Company may process  other  patent  applications  for  additional
products  developed  currently or in the future, to the extent the Company deems
such applications  appropriate.  "mobile mini" and "mobile mini storage systems"
are registered trade names and service marks in the United States and Canada.

The patents as well as the various state trade  secrets acts afford  proprietary
protection to the Company's  products,  including the unique  locking system and
design  of  its  manufactured   products.  The  Company  has  in  place  at  its
manufacturing  facility,   several  access  control  and  proprietary  procedure
policies  to meet  the  requirements  of  protecting  its  trade  secrets  under
applicable law. The Company follows a policy of aggressively  pursuing claims of
patent, tradename, service mark and trade secret infringement.  The Company does
not  believe  that  its  products  and  trademarks  or  other  confidential  and
proprietary rights infringe upon the proprietary rights of third parties.  There
can be no assurance,  however,  that third parties will not assert  infringement
claims against the Company in the future. The successful assertion of rights and
the defense of infringement  claims could have a material  adverse affect on the
Company's business,  results of operations and financial condition. There can be
no assurance that the Company will have sufficient
                                      -5-
<PAGE>
resources  to sustain  expensive  or  protracted  legal  actions to protect  its
proprietary rights or, alternatively, to defend claims of infringement.

Customers

The  market for the  Company's  products  can  generally  be  divided  into four
distinct      areas     --     retail,      residential,      commercial     and
institutional/governmental.  Revenues are derived  from either  rentals or sales
directly to customers or through sales to the Company's dealers.

The  Company's  customer  profile is diverse and does not rely on one  industry.
Instead, the Company targets several different markets within various geographic
areas.  As of December 31, 1997,  the  Company's  leasing and sales clients fall
into the following categories and approximate  percentages:  (i) with respect to
leasing:  retail and wholesale businesses,  47%; homeowners,  17%; construction,
24%; institutions,  7%; government,  industrial and other, 5%; (ii) with respect
to sales: retail and wholesale  businesses,  42%; homeowners,  6%; construction,
13%; institutions, 21%; government, industrial and other, 18%.

Customers utilize the Company's storage units in a variety of ways. For example,
retail  companies  use the  Company's  storage  units for extra  warehousing  of
inventory and records;  real estate development  companies utilize the Company's
products to securely  store  equipment,  tools and materials;  and  governmental
agencies  such as the U.S.  Armed Forces and the U.S.  Drug  Enforcement  Agency
lease  and buy the  Company's  high-security,  portable  storage  units to store
equipment and other goods.

Competition

The Company  competes with its products and services in several market segments,
and the Company  knows of no one entity that is in direct  competition  with the
Company  in all  its  market  segments.  With  respect  to its  on-site  leasing
activities,   the  Company  competes  directly  with  conventional  mini-storage
warehouse facilities and the pick-up and delivery services offered by certain of
these  facilities in the localities in which it operates.  Some of the Company's
on-site leasing competitors include Door to Door Storage, Public Storage, U-Haul
and Shurgard  Storage  Centers.  With respect to off-site leasing and sales, the
Company  has  several  competitors,  which  include  Haulaway,  Mobile  Storage,
National Security  Containers,  and a large number of smaller  competitors.  The
Company  believes  that  its  products,   services,  pricing  and  manufacturing
capabilities  allow it to  compete  favorably  in each of the  on-site  leasing,
off-site  leasing and sales  segments of the  Company's  markets in the areas it
currently operates.

The  Company's  Mobile   Tele-structures   division   competes  against  several
competitors that supply  shelters,  the largest of which the Company believes to
be  Fibrebond  Corporation,  the Rohn  division  of UNR  Industries  and  Andrew
Corporation.

Management believes that the Company has a number of competitive advantages both
in terms of products and operations.  Among its product's  patented  features is
the  locking  system  which  serves  to meet  the  customer's  primary  concern,
security.  Based on reports from customers who have suffered burglary  attempts,
the Company's  locking  system is extremely  difficult to defeat.  The Company's
delivery  trailers  have  largely  been  designed  and built by the  Company and
certain key features have patent  potential which the Company may pursue.  These
proprietary delivery systems, which are specifically designed to transport, load
and unload containers,  allow the Company to deliver containers  economically in
otherwise inaccessible locations.

Operationally,  the  Company  manufactures  containers  from  raw  steel  as  an
alternative to using ocean-going containers. In the event ocean-going containers
are in short  supply  or become  uneconomical  to  retrofit  to the needs of the
Company, the Company can manufacture its own container product. The Company will
continue to manufacture  new storage units for inclusion  primarily in its sales
inventory and also in its lease fleet.

The Company's ability to continue to compete favorably in each of its markets is
dependent  upon  many  factors,   including  the  market  for  used  ocean-going
containers  and the  costs of  steel.  Management  believes  that the  Company's
container manufacturing  capabilities make the Company less susceptible than its
competitors to ocean-going container price fluctuations,  particularly since the
cost of used  containers is affected by many  factors,  only one of which is the
cost of steel from which the Company can manufacture new containers. The Company
has begun to purchase  its raw steel  directly  from steel  mills,  lowering its
average cost of steel.

The Company  believes  that  competition  in each of its  markets  may  increase
significantly  in the future.  It is possible  that such  competitors  will have
greater  marketing  and financial  resources  than the Company.  As  competition
increases, significant pricing
                                      -6-

pressure and reduced profit  margins may result.  Prolonged  price  competition,
along with other forms of competition,  could have a material  adverse affect on
the Company's business and results of operations.  Additionally,  as the Company
continues to expand its operations in different regions, start up costs incurred
reduce the Company's overall profit margins.

Employees

As of March 18, 1998, the Company had  approximately  800 full time employees at
all of its locations. The Company believes that its continued success depends on
its ability to attract and retain  highly  qualified  personnel.  The  Company's
employees are not  represented by a labor union and the Company has no knowledge
of any current  organization  activities.  The Company has never suffered a work
stoppage and considers its relations with employees to be good.

ITEM 2.  DESCRIPTION OF PROPERTY.

The Company has four manufacturing centers located in Maricopa, Arizona, Rialto,
California,  and Houston and  Dallas/Fort  Worth,  Texas.  Sales and leasing are
conducted from Phoenix,  Rialto,  Houston and Dallas/Fort  Worth, and five other
locations.  The Company's administrative and sales offices are located in Tempe,
Arizona.

The Company's primary  manufacturing center is located in a heavy-industry zoned
industrial park near Maricopa, Arizona, approximately 30 miles south of Phoenix.
The  facility  is seven  years  old and is  located  on an  approximate  45 acre
industrial site.  Twenty-three acres of this site were purchased from Richard E.
Bunger in 1996. See, "ITEM 13. CERTAIN RELATIONSHIPS AND RELATED  TRANSACTIONS."
The facility  includes  nine  manufacturing  buildings,  totaling  approximately
158,000 square feet, which house manufacturing, assembly, construction, painting
and vehicle maintenance operations.

The Phoenix,  Arizona sales and leasing branch services the Phoenix metropolitan
area from its  approximately 9.8 acre facility,  of which  approximately 7 acres
are leased. All Phoenix marketing and any on-site storage is conducted from this
site. Approximately 3.4 acres are owned by the Company,  approximately 5.0 acres
are leased from non-affiliated  parties and the remaining 1.4 acres are owned by
members of the Bunger family and are under lease at what management  believes to
be competitive  market rates.  See, "ITEM 13. CERTAIN  RELATIONSHIPS AND RELATED
TRANSACTIONS."

The Rialto,  California sales and leasing hub is approximately 10 acres in size,
with three  industrial  shops used for  modification of ocean-going  containers,
assembly of the Company's manufactured containers and on-site leases. The Rialto
facility  serves as the Company's  southern  California hub and supports the San
Diego branch. The Rialto site is owned by Mobile Mini Systems,  Inc., a separate
corporation  owned by Richard E.  Bunger,  and is leased to the  Company at what
management  believes  to be  competitive  market  rates.  See "ITEM 13.  CERTAIN
RELATIONSHIPS AND RELATED TRANSACTIONS."

The Texas  operations are supported by hub facilities in Houston and Dallas/Fort
Worth.  Both  facilities  contain  manufacturing   centers,  sales  and  leasing
operations and on-site storage  facilities.  The Houston  facility is located on
seven acres with six buildings  totaling  approximately  34,400 square feet. The
Dallas/Fort  Worth  facility,  which is owned by the  Company,  is located on 17
acres with six buildings totaling approximately 36,600 square feet.

The Company's  administrative  and sales offices are located in Tempe,  Arizona.
The  facilities are leased by the Company from an  unaffiliated  third party and
have  approximately  28,800  square feet of space which the Company  anticipates
will meet its needs for the  near-term.  The  Company's  lease  term is  through
December 2000.

In addition to its  administrative  offices and  manufacturing  facilities,  the
Company has facilities used for sales,  leasing and onsite storage.  As of March
1, 1998, the major  properties  owned or leased by the Company are listed in the
table below:

ITEM 3.  LEGAL PROCEEDINGS.

In April 1997,  the Company  entered  into a stock  purchase  agreement  with an
individual  who had  agreed to work for the  Company.  Under the stock  purchase
agreement, the individual was to purchase 500,000 shares of common stock on July
1, 1997. On June 30, 1997, at the individual's request, the Company extended the
closing  date to July 3,  1997.  The  individual  did not  tender  funds  by the
extended  closing  date.  In July  1997,  the  Company  brought  an action in US
District  Court  for the  District  of  Arizona  to have the court  declare  the
Company's  obligations  under  the  stock  purchase  agreement  terminated.  The
individual opposes the Company's request,  and has requested that the Company be
ordered to perform under the stock purchase or, alternatively,  pay him damages,
including treble damages.  In addition,  the individual has filed a counterclaim
alleging constructive  discharge.  The Company is vigorously pursuing the action
and does not believe it will have any material impact on the financial condition
or the results of operations of the Company.

The  Company is not a party to any other  legal  proceeding  other than  various
claims and lawsuits  arising in the normal course of its business  which, in the
opinion  of the  Company's  management,  are not  individually  or  collectively
material to its business.

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

General

The Company was founded in 1983 and operated  only in the Phoenix,  Arizona area
until  1986.  In  1986 it  expanded  to  Tucson,  Arizona,  in 1988 to  southern
California, in 1994 to Texas and in 1998 to Nevada. From inception through 1988,
the  Company  exclusively  engaged in the  refabrication  of  ocean-going  cargo
containers,  which it leased to the public for storage  containers  and portable
offices.  In 1989, the Company began to sell containers.  Contributing to growth
of  sales  revenues  was  the  development  of a  national  distribution  system
(referred to by the Company as the national dealer network),  manufacture of new
Company  designed  containers from raw steel as an alternative and supplement to
the  refabrication of ocean-going  containers,  the manufacture of modular steel
buildings (discontinued in 1996; see "ITEM 1. DESCRIPTION OF BUSINESS - BUSINESS
RESTRUCTURING") and special order products which the Company leases and sells to
schools,   governmental   entities  and  others,  and  the  development  of  the
telecommunication shelter division which commenced operations in mid-year 1995.

The  leasing  of  containers  has  become  the more  significant  portion of the
Company's business and is contributing to the Company's growth.  Since 1993, the
number  of  units  at the  Company's  leasing  locations  has  increased  by the
following percentages as compared to the preceding year:


            December 31,
            ------------

               1993            38%
               1994            62%
               1995            32%
               1996            18%
               1997            33%

As the leasing  operations are the most profitable of the Company's  operations,
management  plans to  increase  the  level of these  operations,  especially  at
existing  locations.  In  addition,  the  Company  expects  to  open  additional
facilities through acquisitions or the start up of new locations on a controlled
basis at  locations  which  management  believes  can become  profitable  over a
relatively short period of time.

The Company  manufactures  and/or  refurbishes  containers  for use in its lease
fleet.   Containers  are  transferred  to  the  lease  fleet  at  cost,  without
recognizing  any  manufacturing  profit  on the value  added to the  refurbished
containers or new containers.  In addition,  the Company's container lease fleet
has been  acquired  over the last 15 years.  During  parts of this  period,  raw
container prices were  significantly  lower than they are today. An appraisal of
the fair market value of the container lease fleet performed in 1997 resulted in
a total  fair  market  value of  approximately  $64,500,000.  This  exceeds  the
carrying  value of the containers by  approximately  $15,800,000 at December 31,
1997.  In  accordance  with  generally  accepted  accounting  principals,   this
differential is not recognized in the Company's financial statements.

Uncertainties  faced by the Company include  variances in start up costs for new
storage  locations,  the availability of acquisitions on terms acceptable to the
Company,  competition  in new  markets,  and the  opportunity  cost of deploying
sufficient  containers in a new market to reach  economic  viability.  While the
Company has  experience  in entering new market  areas and conducts  preliminary
market  research to assure  itself that viable  markets  exist,  there can be no
assurance of success when  expanding  into new  markets.  However,  unlike fixed
mini-storage  facilities,  the Company  does have the  ability to  relocate  its
portable storage containers to other markets to adjust for market demand.

</TABLE>

Fiscal 1997 Compared to Fiscal 1996

The  Company's  business  plan in 1997 was focused on  increasing  its number of
containers on lease at existing branch locations  because the incremental  lease
revenue results in higher margins. In addition,  the Company increased prices on
container sales and withdrew from the low margin modular building business.

Revenues for the year ended December 31, 1997 increased 8.6% to $46,083,000 from
$42,426,000  during 1996.  Revenues from the Company's  leasing  operations were
$24,870,000  which  represents a 39.1%  increase  from 1996 leasing  revenues of
$17,876,000.  This  increase  resulted  from a 33%  increase  in the  number  of
containers  on lease,  and an increase in ancillary  lease revenue per container
resulting  from the  introduction  of the Company's new loss  limitation  waiver
program.  Sales of the Company's products  decreased by 13.1%,  primarily due to
the  discontinuation of the modular building  operations.  This decline in sales
was offset, to some extent, by an approximate $2,200,000 increase in the sale of
telecommunication shelters.

During 1997 the Company  implemented  price  increases on the sale of containers
through its branches and through the National  Dealer  Program.  These  actions,
together with the  withdrawal  from the low margin  modular  building  business,
caused a substantial  increase in gross  margins on sales.  As a result, cost of
containers  and other  sales as of  percentage  of  container  and  other  sales
decreased to 70.9% from 84.4% during 1996.
                                      -12-
<PAGE>
Leasing, selling and general expenses increased 34.2% to $20,585,000 compared to
$15,343,000  in the prior year.  This  increase  was  attributable  to increased
leasing  related  expenses  associated  with the 33%  increase  in the number of
containers  out on lease,  increased  commission  levels  offered  to dealers in
connection with the leasing of containers and increased expenses associated with
developing an infrastructure for future growth.

Depreciation and amortization  increased to 4.9% of revenues in 1997 compared to
4.0% in 1996.  The increase  reflects the  increase in the  Company's  container
lease fleet and support  equipment for  manufacturing  and maintaining the lease
fleet and operational equipment at all the sales and leasing locations.

The Company  recorded a restructuring  charge in 1996 of $700,000.  There was no
similar charge in 1997.

Operating  margins  increased from 11.2% in 1996 to 18.9% in 1997 as a result of
change in the Company's focus to its leasing business,  as well as the increased
gross margins on sales.

Interest expense increased to $5,035,000 in 1997 compared to $3,894,000 in 1996.
The increase in interest expense includes the additional interest related to the
40.8% increase in the Company's average balance of debt outstanding  compared to
1996 and the  amortization of debt issuance costs. The increase in the Company's
average  outstanding  debt is partially  related to the issuance in 1997 of $6.9
million of subordinated  notes and increased  borrowings under the Senior Credit
Agreement  to finance the growth in the  container  lease  fleet.  The  weighted
average  interest  rate  decreased  0.75% in 1997 to 9.45%  from  10.2% in 1996,
excluding  amortization  of  deferred  loan  costs.  Including  amortization  of
deferred loan costs,  the weighted  average  interest rate was 10.61% and 11.56%
for 1997 and 1996, respectively.

The Company generated net income of $2,200,000,  or $0.32 per share diluted,  in
1997 compared to net income before extraordinary item of $481,000,  or $0.07 per
share diluted in 1996. This increase is primarily a result of the 39.1% increase
in leasing  revenues in 1997 and a 14% increase in gross margin on sales in 1997
as compared with 1996. The Company recorded a $700,000  restructuring  charge in
1996.  Excluding the 1996 restructuring  charge,  earnings before  extraordinary
item were approximately $873,000, or $0.13 per share diluted.

In 1996,  the Company  prepaid  approximately  $14.1 million of debt and capital
lease  obligations in connection with entering into the Senior Credit Agreement.
As a result, in 1996 the Company recognized an extraordinary  charge to earnings
of $410,000, or $0.06 per share, net of the benefit of income taxes.

Fiscal 1996 Compared to Fiscal 1995

Revenues for the year ended  December 31, 1996  increased  to  $42,426,000  from
$40,184,000 during 1995.  Revenues during 1995 included  $3,645,000 of container
sale  revenue  recorded  under  sale-leaseback  transactions.  The revenue  from
sale-leaseback  transactions  was offset by an equal cost of container sales and
did not produce any gross margin. The Company did not enter into  sale-leaseback
transactions  during  1996.   Excluding  the  effect  of  these   sale-leaseback
transactions,  revenues  increased  by 16.1%  from 1995 to 1996,  primarily  the
result of increases in both sales and leasing  revenues  generated from existing
branch  locations and the sale of certain used modular  buildings  that had been
previously leased. The Texas operations, which commenced in late 1994, sustained
growth  and  contributed  8.5% and 15.8% to the  Company's  container  sales and
leasing  revenues,  respectively,  during  1996 as  compared  to 7.0% and  9.6%,
respectively,  in  1995.  The  dealer  and  telecommunication  shelter  division
contributed  25.5% and 4.1%,  respectively,  of the  sales  revenues  in 1996 as
compared to 27.2% and 5.8%, respectively, in 1995. Revenues related to container
and modular  building sales and leasing  activities  increased  14.5% and 11.7%,
respectively,  from the prior year, exclusive of container sale revenue recorded
under sale-leaseback transactions.

Excluding  the effect of  sale-leaseback  transactions,  cost of  container  and
modular  building sales as a percentage of container and modular  building sales
increased  to 84.4%  compared  to 74.8% for the prior  year.  This  increase  is
attributable  to the  mix of  products  sold,  a  shortage  in  supply  of  used
containers,   which  caused  an  increase  in  the  acquisition  cost  of  these
containers,  an increase in sales of manufactured new containers which typically
result in lower  margins to the Company,  and an  accounting  refinement  in the
Company's allocation of certain indirect manufacturing costs.
                                      -13-
<PAGE>
Excluding  the  effect of  sale-leaseback  transactions,  leasing,  selling  and
general expenses were 36.2% of total revenue in 1996, compared to 41.5% in 1995.
The decrease primarily resulted from the continued  efficiencies obtained by the
Company's Texas operations,  which were in their start up phase during 1995, and
to the Company passing certain ancillary expenses on to customers.

The  Company  recorded  a  restructuring  charge  (See "ITEM 1.  DESCRIPTION  OF
BUSINESS.-  BUSINESS  RESTRUCTURING")  of $700,000  or 1.6% of total  revenue in
1996. There was no similar charge in 1995.

Income from  operations  was  $4,743,000 in 1996 compared to $4,585,000 in 1995.
Excluding the restructuring charge, income from operations would have been 12.8%
of total revenue in 1996 as compared to 11.4% in 1995.

Interest expense increased to $3,894,000 in 1996 compared to $3,212,000 in 1995.
This increase in interest  expense was primarily the result of a 51.4%  increase
in the  average  balance of debt  outstanding  compared to  1995, along with the
related  amortization of debt issuance costs,  partially offset by a decrease of
3.0% in the Company's  weighted  average  borrowing  rate  resulting  from lower
interest rates under the Company's Senior Credit Agreement.  The additional debt
in 1996 was  incurred  in order  to  finance  the  substantial  increase  in the
Company's equipment and container lease fleet in 1996.

Depreciation and  amortization  increased to 4.0% of revenues in 1996, from 3.3%
in 1995, and is directly related to the expansion of the Company's manufacturing
facility  along with the  substantial  growth in the  Company's  lease fleet and
additional support equipment at the Company's sales and leasing locations.

The Company had income before extraordinary item of $481,000,  or $.07 per share
diluted,  in 1996,  compared to net income of $777,000 or $.16 per share diluted
in 1995 before the effect of dividends  on the  Company's  Series A  Convertible
Preferred  Stock of $(.25) per share diluted (see notes 1 and 11 of the Notes to
Consolidated  Financial  Statements).  This decrease primarily resulted from the
$700,000  restructuring  charge recorded by the Company in the fourth quarter of
1996,  discussed  above.  See  "Item  1.  DESCRIPTION  OF  BUSINESS  -  BUSINESS
RESTRUCTURING".  Excluding this charge, 1996 earnings before  extraordinary item
were approximately  $873,000, or $.13 per share. The weighted average common and
common  equivalent  shares  outstanding at the end of 1996 increased by 39% from
the prior year due to the issuance of  additional  common stock in 1996 pursuant
to the conversion of the Series A Convertible Preferred Stock, issued during the
fourth quarter of 1995, which was converted to common stock in 1996.

The Company  prepaid  approximately  $14.1 million of debt and capital leases in
connection  with entering  into the Senior Credit  Agreement in March 1996. As a
result, the Company recognized an extraordinary  charge to earnings of $410,000,
or $.06 per share,  net of the  benefit  for income  taxes,  as a result of this
early  extinguishment  of debt.  The Company also  incurred  financing  costs of
$2,000,000  in  connection  with the Senior  Credit  Agreement,  which have been
deferred and are being amortized over the term of the Senior Credit Agreement.

Quarterly  results can be affected by a number of factors,  including the timing
of orders,  customer delivery requirements,  production delays,  inefficiencies,
the mix of product  sales and  leases,  raw  material  availability  and general
economic conditions.

Seasonality

Demand for off-site container leases is stronger from September through December
due to  increased  needs for storing  inventory  for the  holiday  season by the
Company's  retail  customers.  Containers  used by  these  customers  are  often
returned  early in the  following  year,  usually  causing a lower  than  normal
occupancy rate for the Company during the first  quarter.  The occupancy  levels
have  historically  ranged from a low of 82% to a high of 95%. These  seasonable
fluctuations  created  a  marginal  decrease  in cash flow for each of the first
quarters during the past several years.

Liquidity and Capital Resources

The Company required increased amounts of financing to support the growth of its
business  during  the last  several  years.  This  financing  has been  required
primarily  to  fund  the  acquisition  and  manufacture  of  containers  for the
Company's lease fleet, the acquisition of property,  plant and equipment and the
expansion of the Company's manufacturing facilities.

In February  1998, the Company  received  proceeds of $5.2 million in connection
with the  exercise of warrants to purchase  1,046,000  shares of common stock at
$5.00 per share. These warrants had been issued in connection with the Company's
initial public offering in 1994.

In October  1997,  the Company  issued $6.9  million of 12% Senior  Subordinated
Notes  ("Notes")  with  redeemable  warrants to purchase  172,500  shares of the
Company's  common stock at $5.00 per share.  The Notes are due November 1, 2002.
From the net proceeds of the sale of the Notes,  the Company repaid $3.0 million
in bridge notes issued in July 1997 and reduced the borrowings outstanding under
the  revolving  line of  credit  under  the  Senior  Credit  Agreement  with the
remainder of the net proceeds.  Because the Notes were offered as part of a unit
with Redeemable  Warrants,  a portion of the original  offering price for a unit
was  allocated to the Notes and a portion to the  Redeemable  Warrants  based on
their  respective  fair market  values.  The  resulting  discount  increases the
effective  interest rate of the Notes and is being amortized to interest expense
over the life of the Notes.

The indenture  related to 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. The
Company has been in compliance with the financial covenants at all determination
dates.

In order to improve its cash flow, increase its borrowing  availability and fund
its continued  growth,  in March 1996 the Company entered into the Senior Credit
Agreement with BT Commercial  Corporation,  as Agent for a group of lenders (the
"Lenders"). Under the terms of the Senior Credit Agreement, the Lenders provided
the Company with a $35.0 million  revolving  line of credit,  amended in 1997 to
$40.0 million, and a $6.0 million term loan.  Borrowings under the Senior Credit
Agreement are secured by substantially all of the Company's assets.

Borrowings  under  the  term  loan are to be  repaid  over a  five-year  period.
Interest  accrues on the term loan at the Company's  option at either prime plus
1.75% or the  Eurodollar  rate plus  3.25%.  Borrowings  under the term loan are
payable monthly as follows (plus interest):


        Months 1  through 12 (April 1996 - March 1997) . . .    $ 62,500
        Months 13 through 24 (April 1997 - March 1998) . . .      83,333
        Months 25 through 60 (April 1998 - March 2001) . . .     118,056

Additional  principal  payments  equal to 75% of Excess Cash Flow, as defined in
the term loan documents which  constitute  part of the Senior Credit  Agreement,
are  required  annually.  As of  December  31, 1997, no  additional  payment was
required under this provision.

Available borrowings under the revolving line of credit are based upon the level
of the  Company's  inventories,  receivables  and  container  lease  fleet.  The
container lease fleet will be appraised at least annually,  and up to 90% of the
lesser of cost or  appraised  orderly  liquidation  value may be included in the
borrowing base.  Interest  accrues at the Company's  option at either prime plus
1.5% or the Eurodollar  rate plus 3% and is payable monthly or at the end of the
term of any  Eurodollar  borrowing  period.  The term of this  revolving line of
credit is three  years,  with a one-year  extension  option.  As of December 31,
1997,  $35.9 million of  borrowings  were  outstanding  and  approximately  $4.1
million of  additional  borrowing  was  available  under the  revolving  line of
credit.  At March 18, 1998,  $35.1 million of borrowings  were  outstanding  and
approximately $4.9 million of additional borrowing was available.
                                      -16-

The Senior Credit Agreement  contains several  financial  covenants  including a
minimum tangible net worth requirement, a minimum fixed charge coverage ratio, a
maximum ratio of  debt-to-equity,  minimum  operating  income levels and minimum
required  utilization  rates. In addition,  the Senior Credit Agreement contains
limits on capital expenditures, acquisitions, changes in control, the incurrence
of  additional  debt,  and the  repurchase  of common  stock,  and prohibits the
payment of  dividends.  The Company has been in compliance  with such  financial
covenants at all determination dates.

During 1997, the Company's operations provided cash flow of $6,077,000, compared
to utilizing $1,390,000 in 1996. The improvement in cash flow resulted primarily
from  improved  operating  results  achieved  in  1997.  Cash  flow in 1996  was
adversely  affected by a reduction of accounts  payables  partially offset by an
increase in leasing receivables which typically have a longer turnover period.

During 1997,  the Company  invested  $19,219,000  in equipment and the container
lease fleet.  This amount is net of $2,447,000 in container  sales and equipment
financing.

Cash flow from financing  activities  totaled  $13,410,000 during 1997. This was
the result of  increased  borrowings, under the  revolving  line of  credit,  to
finance  container lease fleet and equipment  acquisitions,  and the issuance of
the Notes,  partially  offset by the  principal  payments  on  indebtedness  and
additional financing costs incurred.

The Company believes that its current  capitalization,  together with borrowings
available  under the Senior  Credit  Agreement,  is  sufficient  to maintain its
current level of operations and permit a modest level of growth. However, should
demand for the Company's  products  continue to grow at a significant  rate, the
Company  would 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 obtained or
obtained on terms acceptable to the Company.

FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS

The Company issued and sold $6,900,000 of 12% Senior Subordinated Notes due 2002
and Redeemable  Warrants to purchase  shares of the Company's  common stock,  in
October 1997, in a public offering subject to its  Registration  Statement dated
August 26, 1997, as amended  (Securities  and Exchange  Commission  ("SEC") File
Number 333-34413).  That Registration Statement and the Prospectus dated October
8, 1997,  which is a part of it (the  "Prospectus"),  include a section entitled
"Risk Factors," which describes certain factors that may affect future operating
results of the Company. That section is hereby incorporated by reference in this
Report. Those factors should be considered carefully in evaluating an investment
in the Company's Common Stock or other securities.  You may obtain a copy of the
Prospectus by request to the Company's Investor  Relations  Department by phone,
at (602)  894-6311,  or by mail at Mobile Mini,  Inc.,  1834 West Third  Street,
Tempe,  Arizona 85281. The Prospectus is also available  through the SEC's EDGAR
Database  on  the  World  Wide  Web  through  the  SEC's  Internet   address  at

"Safe Harbor"  Statement under the Private  Securities  Litigation Reform Act of
1995

The statements  contained in this Report which are not  historical  facts may be
deemed to  contain  forward-looking  statements  with  respect  to  events,  the
occurrence  of  which  involve  risks  and  uncertainties,   including,  without
limitation,  demand for the  Company's  products  and  services.  The  continued
availability to the Company of adequate financing, the ability of the Company to
manage  its  growth,  and other  risks or other  uncertainties  detailed  in the
Company's SEC filing, including the Prospectus.

Year 2000 Compliance

The Company has recently  upgraded its primary  system using  software  that has
been  certified  by  the  vendor  to be  fully  compliant  with  the  Year  2000
transactions.  The Company has begun to test this  software for such  compliance
and is developing a plan to assure that all other Company  systems are Year 2000
compliant.  Such plan will  include  testing all  computers  and making sure all
software is upgraded to versions that are Year 2000 compliant.  The Company does
not  anticipate  any material  impact to its  financial  condition or results of
operations  as a result of any failure by the Company to have  systems  that are
Year  2000  compliant.  The  Company  does not  believe  that a  failure  of its
customers to be Year 2000 compliant  will have a material  adverse effect on the
Company,  since the principal effect which the Company foresees is late payments
if customer computer systems fail to track the correct date.

                    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 1996,
and the related consolidated statements of operations,  stockholders' equity and
cash flows for each of the three years in the period  ended  December  31, 1997.
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 the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  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  1996  and the  results  of  their
operations  and their cash flows for each of the three years in the period ended
December 31, 1997, 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.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                DECEMBER 31, 1997

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

         Organization

Mobile Mini, Inc., a Delaware  corporation,  designs and  manufactures  portable
steel  storage  containers  and  telecommunications  shelters  and  acquires and
refurbishes  ocean-going  shipping  containers  for sale and lease  primarily in
Arizona,  California,  Texas and  Nevada.  It also  designs and  manufactures  a
variety of  delivery  systems to  compliment  its  storage  container  sales and
leasing activities.

         Principles of Consolidation

The consolidated  financial statements include the accounts of Mobile Mini, Inc.
and its wholly owned  subsidiaries,  Delivery Design Systems,  Inc.  ("DDS") and
Mobile Mini I, Inc.  (collectively  the  "Company").  All material  intercompany
transactions have been eliminated. Certain amounts in the accompanying financial
statements  have been  reclassified  to  conform  to  current  year's  financial
presentation.

         Management's Plans

The Company has  experienced  rapid growth  during the last  several  years with
lease revenues  increasing at a 41% compounded  rate during the last four years.
This growth related to both the opening of additional  sales and leasing offices
in  California  and Texas and to an  increase  in  leasing  revenues  due to the
expansion of the Company's container lease fleet.

As  discussed  more fully in Note 3, in March 1996,  the Company  entered into a
$41.0  million  credit  agreement  (the  "Senior  Credit   Agreement")  with  BT
Commercial  Corporation,  as  Agent  for a group  of  lenders  (the  "Lenders").
Initially,  the  Senior  Credit  Agreement  provided  a $6.0  million  term loan
facility and a $35.0 million line of credit. Initial borrowings under the Senior
Credit  Agreement  of  $22,592,000  were used to  refinance  a  majority  of the
Company's then outstanding  indebtedness with the more favorable terms available
under the Senior Credit Agreement.  The Company's revolving line of credit under
the Senior Credit  Agreement  was increased  from $35.0 million to $40.0 million
during 1997. The Company  intends to use its remaining  borrowing  availability,
primarily to expand its container lease fleet and related operations.

The Company believes that its current  capitalization,  together with borrowings
available  under the Senior  Credit  Agreement,  is  sufficient  to maintain its
current  level  of  operations  and  permit   controlled  growth  and  increased
profitability.  However,  should demand for the Company's  products  continue to
grow at a significant  rate, the Company would be required to secure  additional
financing  through  additional  borrowings,  debt  or  equity  offerings,  or  a
combination of these sources.  The Company  believes that such financing will be
available;  however,  there is no  assurance  that any such  financings  will be
obtained or obtained 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 manufactured
containers.  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  container  leasing
operations.  It could also cause the appraised orderly  liquidation value of the
containers in the lease fleet to decline.  In such event, the Company's  ability
to finance its business  through the Senior Credit  Agreement  would be severely
limited as the maximum  borrowing  limit  under that  facility is based upon the
appraised orderly liquidation value of the Company's container lease fleet.
                                      -25-

The Company  previously  was  involved in the  manufacture,  sale and leasing of
modular  steel  buildings  in the state of Arizona.  These  buildings  were used
primarily  as  portable  schools,  but could be used for a variety of  purposes.
Although  the  Company  believes  its  modular  buildings  were  superior to the
wood-framed  buildings  offered by its competitors,  the Company was not able to
generate  acceptable  margins on this product  line.  During  1996,  the Company
implemented a strategic restructuring program designed to concentrate management
effort and resources and better position itself to achieve its strategic  growth
objectives.  As a result of this  program,  the Company's  1996 results  include
charges of $700,000 ($400,000 after tax, or $.06 per share) for costs associated
with restructuring the Company's manufacturing  operations and for other related
charges.  These  charges were recorded in the fourth  quarter of 1996,  and were
comprised of the write-down of assets used in the Company's discontinued modular
building  operations  and  related  severance  obligations  ($300,000),  and the
write-down  of other  fixed  assets  ($400,000).  By  discontinuing  its modular
building  operations,  the  Company  will  be  able to  utilize  the  management
resources and production capacity previously utilized by this division to expand
the Company's  telecommunications  shelter  business and its  container  leasing
operations.

         Revenue Recognition

The Company recognizes  revenue from sales of containers upon delivery.  Revenue
generated under container leases is recognized on a straight-line basis over the
term of the related lease.

Revenue under certain  contracts for the  manufacture  of modular  buildings and
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   incomplete   contracts   is
approximately  $307,000 at December 31, 1997 and are included in  receivables in
the accompanying  consolidated  balance sheet. Costs and estimated earnings less
billings on incomplete  contracts of approximately  $141,000 in 1996,  represent
amounts  received in excess of revenue  recognized  and are  included in accrued
liabilities in the accompanying consolidated balance sheet.

Revenue for container delivery, pick-up and hauling is recognized as the related
services are provided.

         Concentrations of Credit Risk

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

The Company's sales and leasing  customers by major category are presented below
as a percentage of units leased/sold:

         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:

         Earnings (Loss) Per Share
                                      -27-
<PAGE>
During 1997, the Company adopted SFAS No. 128,  Earnings per Share.  Pursuant to
SFAS No. 128,  basic  earnings  per common  share are  computed by dividing  net
income  (loss)  by the  weighted  average  number  of  shares  of  common  stock
outstanding  during the year.  Diluted  earnings  (loss)  per  common  share are
determined assuming that options were exercised at the beginning of each year or
at the time of issuance. No outstanding options were assumed to be exercised for
purposes of calculating  diluted  earnings per share for the year ended December
31,  1995 as their  effect  was  anti-dilutive.  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.

         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,  receivables and accounts payable approximate fair
values. The carrying amounts of the Company's borrowing under the revolving line
of credit and long-term debt instruments  approximate fair value. The fair value
of the Company's  long-term debt 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.

         Deferred Financing Costs

Included  in  other  assets  are  deferred   financing  costs  of  approximately
$2,104,000  and  $1,659,000 at December 31, 1997 and 1996,  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
                                      -28-
<PAGE>
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.

(2)      CONTAINER LEASE FLEET:

The Company has a container lease fleet consisting of refurbished or constructed
containers and modular  buildings that are leased to customers  under  operating
lease  agreements  with varying terms.  The  containers on lease,  excluding the
modular  buildings,  are leased to customers  under short term  operating  lease
agreements.  Depreciation  is provided using the  straight-line  method over the
containers'  and  modular  buildings'  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.
Containers and modular  buildings  included in the container lease fleet with an
original loan value of approximately $9.2 million at December 31, 1997 and 1996,
have been pledged as collateral for notes payable and obligations  under capital
leases. The balance of the containers are pledged as collateral under the Senior
Credit  Agreement (see Notes 3, 4 and 5). Normal repairs and  maintenance to the
containers and modular buildings are expensed as incurred.

Container   lease  fleet  includes  assets  acquired  under  capital  leases  of
approximately  $8,255,000  and  $8,043,000,   and  accumulated  amortization  of
approximately $317,000 and $204,000 at December 31, 1997 and 1996, respectively.

(3)      LINE OF CREDIT:

In March 1996, the Company entered into the Senior Credit  Agreement.  Under the
terms of the Senior Credit Agreement,  as amended, the Lenders have provided the
Company with a $40.0  million  revolving  line of credit and a $6.0 million term
loan.  Borrowings under the Senior Credit Agreement 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  container  lease  fleet.  The
container  lease  fleet is  appraised  at lease  annually,  and up to 90% of the
lesser of cost or  appraised  orderly  liquidation  value,  as  defined,  may be
included in the borrowing  base.  Interest  accrues at the  Company's  option at
either prime plus 1.5% or the  Eurodollar  rate plus 3% and is payable  monthly.
The term of this  line of  credit  is three  years,  with a  one-year  extension
option.

In  connection  with the  closing of the Senior  Credit  Agreement,  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 resulted in an extraordinary charge to earnings in 1996
of $410,000 after benefit for income taxes.

The  revolving  line of credit  balance  outstanding  at December 31, 1997,  was
approximately   $35.9   million.   The  amount   available   for  borrowing  was
approximately  $4.1 million at December 31, 1997. Prior to the refinancing,  the
Company had  available  short-term  lines of credit which bore  interest at 1.5%
over the prime rate.  During 1997 and 1996, the weighted  average  interest rate
under the lines of credit was 8.93% and  8.73%,  respectively,  and the  average
balance  outstanding  during 1997 and 1996 was  approximately  $32.2 million and
$20.3 million, respectively.

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

Additional  principal  payments  equal to 75% of Excess Cash Flow, as defined in
the term loan documents which  constitute  part of the Senior Credit  Agreement,
are  required  annually.  As of December  31, 1997,  no  additional  payment was
required under this provision.

The Senior Credit Agreement contains restrictive covenants. See Note 3

(5)      OBLIGATIONS UNDER CAPITAL LEASES:

The Company leases certain storage containers and equipment under capital leases
expiring through 2001.  Certain storage container leases were entered into 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  containers.  These leases
have been capitalized using interest rates ranging from approximately 8% to 14%.
The leases are secured by storage containers and equipment under lease.

During 1995 and 1994,  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  financial
institution   (the   "Assignee").   In  addition,   the  Company   entered  into
Remarketing/Releasing  Agreements  (the  "Agreements")  with the  Assignee.  The
Agreements provide that the Company will be the exclusive  selling/leasing agent
upon the termination of the aforementioned  Leases for a period of 12 months. If
the Company is successful in releasing the
                                      -30-
<PAGE>
buildings and the Assignee receives,  via lease payments, an amount equal to the
Base Price, as defined,  plus any reimbursed  remarketing  costs of the Company,
the Company has the option to  repurchase  the  buildings for $1.00 each. If the
Company sells any of the  buildings,  the Assignee  shall receive from each sale
that portion of the Base Price  allocated  to the  building  sold plus costs the
Assignee has reimbursed to the Company plus interest on those  combined  amounts
from the date of the Lease termination at the Assignee's prime rate plus 4%. Any
sales proceeds in excess of this amount are to be remitted to the Company.

In the event the Company has not released or sold the buildings within 12 months
of the  termination  of the Leases,  the  Assignee  has the right to require the
Company  to  repurchase  the  buildings  for the Base  Price  plus all costs the
Assignee has  reimbursed to the Company plus interest  thereon at the Assignee's
prime rate plus 4% since the termination of the Lease.  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 buildings  matured and the Company sold all 15
portable  buildings in 1996 pursuant to the Agreements.  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 at
December 31, 1996.

Certain  obligations  under capital leases  contain  financial  covenants  which
include that the Company  maintain a specified  interest  expense coverage ratio
and a required debt to tangible net worth 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  1996,  approximated  $271,000  and  $288,000,
respectively,  and are reflected as a reduction in the container  lease fleet in
the accompanying consolidated financial statements.

Included in the accompanying  consolidated statements of operations are revenues
of  approximately  $3,645,000 in 1995 for container  sales under  sale-leaseback
transactions where no profit was recognized.  The Company did not enter into any
significant sale-leaseback transactions either in 1996 or 1997.

(6)      12% SENIOR SUBORDINATED NOTES:

In October  1997,  the Company  issued $6.9  million of 12% Senior  Subordinated
Notes ("Notes") with a scheduled maturity date of November 1, 2002 and which are
considered  unsecured  obligations of the Company. The Notes were issued as part
of a unit with Redeemable  Warrants to purchase  172,500 shares of the Company's
common stock at $5.00 per share. 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. Interest is payable semi-annually on May 1 and
November  1 of each year,  commencing  May 1,  1998.  The Notes  were  issued in
denominations and integral  multiples of $5,000.  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.

As of December 31, 1997, the  outstanding  balance of the Notes was  $6,647,874,
net of the remaining unamortized discount of approximately $252,000.
                                      -31-
<PAGE>
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 Bridge Notes were
due the earlier of July 31, 2002, or on the  refinancing  of the Bridge Notes on
substantially similar terms. 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.

The Indenture  governing  the notes  requires the Company to comply with certain
covenants  including  maintaining a specific tangible net worth, a maximum total
funded indebtedness ratio and a maximum senior funded indebtedness ratio.

(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, 1997,  1996 and 1995 consisted of
the following:

The Company has a federal net operating  loss  carryover at December 31, 1997 of
approximately $10,775,000 which expires if unused in years 2008 to 2012.

As a result of stock ownership changes during 1996 and 1997, it is possible that
the Company has undergone  one or more changes in ownership  which can limit the
amount of net operating  loss that is 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 is not necessary at December 31, 1997.

(8)      TRANSACTIONS WITH RELATED PARTIES:

Effective December 31, 1993,  Richard E. Bunger, an executive officer,  director
and  founder of the  Company,  contributed  substantially  all of the assets and
liabilities  of  MMSS  and the  stock  of DDS to the  Company  in  exchange  for
2,700,000  shares of Common Stock and the  assumption of certain  liabilities by
the Company.  Such  liabilities  include  liabilities  associated  with the MMSS
assets and operations  and certain  income tax  liabilities of Mr. Bunger and an
affiliate  arising from the MMSS operations  occurring prior to January 1, 1994.
Such income tax liabilities  were estimated at $428,000 which were  subsequently
paid by the Company.  Deferred income tax liabilities associated with the assets
contributed,  established at $2,393,000,  were also required to be recognized by
the Company in connection with such  capitalization.  The Company will indemnify
and defend Mr. Bunger against loss or expense related to all liabilities assumed
by the Company and for any contingent  liabilities arising from past operations.
Prior to the capitalization of the Company, Mr. Bunger personally guaranteed the
Company's  lines of credit and other  material  debts.  These  obligations  have
subsequently been extinguished through payment by the Company.

The Company leases a portion of the property comprising its Phoenix location and
the property  comprising  its Tucson  location from Mr.  Bunger's five children.
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., an affiliate, 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 reflected the
fair market  value of the  property.  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.

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 to Steven G.
Bunger.  The  Company  made  aggregate  payments  of  approximately  $73,000  to
Skilquest,  Inc. in 1997 which the  Company  believes  reflects  the fair market
value for the services performed.

(9)      BENEFIT PLANS:

Stock Option Plan

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

Under the Plan,  as  amended in 1997,  options to  purchase a maximum of 750,000
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 such options will be granted, whether such options will
be ISOs or non-qualified options,  which directors,  officers, key personnel and
service   providers  will  be  granted  options,   the  restrictions   upon  the
forfeitablity  of such options and the number of options to be granted,  subject
to the  aggregate  maximum  number set forth  above.  Each option  granted  must
terminate no more than 10 years from the date it is granted.
                                      -33
<PAGE>
The board of directors  may amend the Plan at any time,  except that approval by
the Company's  shareholders may be 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 such  options,  modifies the period within
which the options may be granted,  modifies the period  within which the 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  throughout the
term of such option.

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 fiscal 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:

         Risk free interest rates range            6.0 to 6.6%
         Expected holding period                     4.0 years
         Dividend rate                                    0.0%
         Expected volatility                             55.4%

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

                                          1997          1996          1995

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  (loss) or
earnings  (loss) 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.

401(k) Plan

In 1995,  the Company  established a contributory  retirement  plan (the "401(k)
Plan") covering eligible employees with at least one year of service. The 401(k)
Plan is designed to provide  tax-deferred  income 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 their respective  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 during 1996 or 1995. In 1997
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  noncancelable
operating  leases with related  parties.  The Company also leases its  corporate
offices and other properties,  as well as operating equipment from third parties
under noncancelable operating
                                      -35-
<PAGE>
leases.  Rent  expense  under  these  agreements  was  approximately   $932,000,
$649,000,  and $515,000 for the years ended  December 31, 1997,  1996, and 1995,
respectively.  Total future  commitments under all noncancelable  agreements for
the years ended December 31, are approximately as follows:

         1998                      $  999,000
         1999                       1,003,000
         2000                         943,000

         2002                         582,000
         Thereafter                 3,201,000
                                    ---------
                                   $7,486,000
                                    =========

In April 1997,  the Company  entered  into a stock  purchase  agreement  with an
individual  who had  agreed to work for the  Company.  Under the stock  purchase
agreement, the individual was to purchase 500,000 shares of common stock on July
1, 1997. On June 30, 1997, at the individual's request, the Company extended the
closing  date to July 3,  1997.  The  individual  did not  tender  funds  by the
extended  closing  date.  In July  1997,  the  Company  brought  an action in US
District  Court  for the  District  of  Arizona  to have the court  declare  the
Company's  obligations  under  the  stock  purchase  agreement  terminated.  The
individual opposes the Company's request,  and has requested that the Company be
ordered to perform under the stock purchase or, alternatively,  pay him damages,
including treble damages.  In addition,  the individual has filed a counterclaim
alleging constructive  discharge.  The Company is vigorously pursuing the action
and does not believe it will have any material impact on the financial condition
or the results of operations of the Company.

The  Company is involved in certain  administrative  proceedings  arising in the
normal course of business. In the opinion of management, the Company's potential
exposure under the pending administrative 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:

Initial Public Offering

In February 1994, the Company successfully  completed an initial public offering
of 937,500  Units,  each Unit  consisting  of two shares of common stock and one
detachable  warrant  (the  "Warrants")  for the  purchase of one share of common
stock for $5.00 per share,  which  expired on February 17, 1998.  An  additional
130,000   Units  were  sold  in  March  1994   pursuant  to  the   underwriters'
over-allotment  option.  Net proceeds to the Company totaled  $7,027,118.  

The Company also granted the  underwriters a warrant  ("Underwriters'  Warrant")
for the purchase of an additional  93,750 Units.  The  Underwriters'  Warrant is
exercisable  for four years,  commencing  on February 17,  1995,  at an exercise
price of $12.00 per unit.  As of  December  31,  1997,  none of the  Warrants or
Underwriters' Warrants had been exercised.

Series A Convertible Preferred Stock

In December 1995, the Company  completed the private  placement of 50,000 shares
of Series A Convertible  Preferred  Stock  ("Series  A"),  $.01 par value,  $100
stated value, for aggregate net proceeds of $4.1 million.  Pursuant to the terms
of the Series A, all 50,000  shares of Series A were  converted  into  1,904,324
shares of the Company's common stock at an average  conversion rate of $2.63 per
share  during the first  quarter of 1996,  at which time all such  shares of the
Series A convertible  Preferred  Stock became  authorized but unissued shares of
Preferred Stock which may be reissued.

In connection with the issuance of the Series A the Company recorded a preferred
stock  dividend of  $1,250,000  at  December  31,  1995 in  accordance  with the
accounting  treatment  announced  by the staff of the SEC at the March 13,  1997
meeting of the Emerging  Issues Task Force whereas the Series A had  "beneficial
conversion"  features  which  permitted the holder to convert their  holdings to
common  shares at a fixed  discount off of the market price of the common shares
when converted. The effect of the dividend resulted
                                      -36-
<PAGE>
in a decrease in earnings per share  applicable to common  shareholders of $.25,
however, the recognition in the calculation of earnings (loss) per share did not
have any effect on the cash flows of the Company.

Redeemable Warrants

Redeemable  Warrants to purchase 187,500 shares of the Company's common stock at
$5.00 per share  (subject  to  adjustment  as  described  below)  were issued in
connection  with the  issuance of the Notes (Note 6). A portion of the  original
offering price was allocated to the Notes and the  Redeemable  Warrants based on
their relative fair values. The Redeemable  Warrants first become 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,  among other things,
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.

(12)     SUBSEQUENT EVENTS:

On January 20, 1998 the Company acquired the assets of Nevada Storage Containers
("NSC"),  a Las Vegas based container  leasing and sales business.  The purchase
price  included  approximately  $1.4  million in cash and  approximately  85,000
shares of the Company's  common stock.  The Company  acquired  NSC's  containers
under lease to  customers  and other  operating  equipment.  Under the  purchase
agreement,  the shares of common  stock will not be issued  until one year after
the closing date.

As of their  expiration  date of February 17, 1998,  1,046,212 of the  1,067,500
warrants  issued in connection  with the Company's  initial  public  offering in
February  1994,  have  been  exercised  for an equal  amount  of  shares  of the
Company's  common stock. The Company  received  proceeds of  approximately  $5.2
million which the Company intends to use for working capital purposes.

insurance  policy,  a  Company  owned  vehicle,  and all the  employee  benefits
provided to the Company's executive employees.

         Although  the  Company has not entered  into any  long-term  employment
contracts  with any of its  employees,  the Company has  entered  into  numerous
agreements  with key employees  which are  terminable  at will,  with or without
cause,  including  agreements with Steven G. Bunger,  Lawrence  Trachtenberg and
Burton K.  Kennedy  Jr.  Each of these  agreements  contains a  covenant  not to
compete for a period of two years after termination of employment and a covenant
not to  disclose  confidential  information  of a  proprietary  nature  to third
parties.

         The Company had numerous bonus and incentive  arrangements with several
employees during 1997,  including Mr. Richard Bunger,  Mr. Steven G. Bunger, Mr.
Trachtenberg and Mr. Kennedy.  These agreements included an incentive program to
provide  financial  awards for an increase in revenues or for the  attainment of
quotas. These compensation agreements were evaluated by an independent executive
compensation  consulting organization and effective January 1, 1997, these above
named  employees  were  compensated  in 1997 based on  commensurate  fair market
salaries plus an incentive program.

Compensation of Directors

         The Company's  directors  (other than directors who are officers of the
Company)  received cash  compensation  for service on the Board of Directors and
committees thereof in the amount of $500 per quarterly meeting.  Prior to August
1, 1997,  non-employee  directors  had the right to  receive  options to acquire
3,000  shares of Common  Stock on each August 1 while  serving as members of the
compensation  committee;  from and after August 1, 1997,  this was  increased to
7,500 shares of common stock on each August 1.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

The Company  leases  certain of its business  locations  from  affiliates of Mr.
Richard E. Bunger,  including his children.  Mr. Bunger is an executive officer,
director and founder of the  Company.  The Company  entered  into an  agreement,
effective  January 1, 1994,  to lease a portion of the property  comprising  its
Phoenix location and the property comprising its Tucson location from Richard E.
Bunger's  five  children.  Total annual base lease  payments  under these leases
currently  equal  $66,000,  with annual  adjustment  based on the consumer price
index.  Lease payments in fiscal year 1997 equaled $71,824.  The term of each of
these leases will expire on December 31, 2003.  Prior to 1994,  these properties
were leased by the  Company's  predecessor  at annual rental  payments  equaling
$14,000.  Additionally,  the Company entered into an agreement effective January
1, 1994 to lease its Rialto  facility from Mobile Mini  Systems,  Inc. for total
annual  base lease  payments of $204,000  with annual  adjustments  based on the
consumer price index.  This lease agreement was extended for and additional five
years during 1996. Lease payments in fiscal year 1997 equaled $222,000. Prior to
1994, the Rialto site was leased to the Company's  predecessor at an annual rate
of $132,000.  Management  believes the increase in rental rates reflect the fair
market  rental  value of these  properties.  Prior to the  effectiveness  of the
written  leases,  the terms  were  approved  by the  Company's  independent  and
disinterested directors.

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

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 to Steven G.
Bunger.  The  Company  made  aggregate  payments  of  approximately  $73,000  to
Skilquest,  Inc. in 1997 which the  Company  believes  reflects  the fair market
value for the services performed.

Law of the State of Delaware.

         FOURTH:  The total  number of shares of all  classes of stock which the
Corporation shall have authority to issue is twenty-two million  (22,000,000) of
which  seventeen  million  (17,000,000)  shares shall be common stock of the par
value of one cent ($0.01) per share and five million (5,000,000) shares shall be
preferred stock with the par value of one cent ($0.01) per share.

                  As to preferred  stock, the power to issue any shares of stock
of any class or any  series of any class and to  designate  the  voting  powers,
designations, preferences, and relative participating, optional or other rights,

                  Cumulative voting as provided for by Section 214 of Title 8 of

         FIFTH: [Name of Incorporator -- intentionally omitted.]

         SIXTH: The Corporation is to have perpetual existence.

         SEVENTH:  Whenever a compromise or arrangement is proposed  between the

<PAGE>
stockholders  or any class of them, any court of equitable  jurisdiction  within
the  State  of  Delaware  may,  on  the  application  in a  summary  way  of the
Corporation or any of any creditor or stockholder  thereof or on the application
of any receiver or receivers  appointed for the Corporation under the provisions
of Section 291 of Title 8 of the Delaware code or on the application of trustees
in  dissolution  or of any receiver or receivers  appointed for the  Corporation
under the  provisions  of Section  279 of Title 8 of the  Delaware  Code order a
meeting of the creditors or class of creditors,  and/or of the  stockholders  or
class of stockholders of the Corporation,  as the case may be, to be summoned in
such  manner as the said court  directs.  If a majority  in number  representing
three-fourths  in value of the  creditors or class of  creditors,  and/or of the
stockholders or class of stockholders  of the  Corporation,  as the case may be,
agree  to  any  compromise  or  arrangement  and to  any  reorganization  of the
Corporation  as  consequence  of  such  compromise  or  arrangement,   the  said
compromise or arrangement  and the said  reorganization  shall, if sanctioned by
the  court  to which  the  application  has been  made,  be  binding  on all the
creditors  or class of  creditors,  and/or on all the  stockholders  or class of
stockholders,  of  the  Corporation,  as  the  case  may  be,  and  also  on the
Corporation.

         EIGHTH:  The number of Directors of the Corporation  shall be a minimum
of three (3) and a maximum of  thirteen  (13)  persons.  The Board of  Directors
shall have sole  authority  to  determine  the number of  Directors,  within the
limits set forth  herein,  and may  increase  or  decrease  the exact  number of
Directors from time by resolution duly adopted by such Board. No decrease in the
number  of  Directors  shall  have  the  effect  of  shortening  the term of any
incumbent  Director.  The exact number of  Directors  shall be five (5) until so
increased or decreased.

                  The  number  of  Directors  shall be  divided  into  three (3)
classes,  as nearly  equal in  number as may be, to serve in the first  instance
until the first,  second and third  annual  meetings of the  stockholders  to be
held,  respectively,  and until  their  successors  shall be  elected  and shall
qualify.  In the  case  of  any  increase  in the  number  of  Directors  of the
Corporation, the additional Directors shall be so classified that all classes of
Directors  shall be  increased  equally as nearly as may be, and the  additional
Directors  shall be  elected  as  provided  herein  by the  Directors  or by the
stockholders  at an annual  meeting.  In case of any  decrease  in the number of
Directors  of the  Corporation,  all  classes of  Directors  shall be  decreased
equally,  as nearly as may be.  Election  of  Directors  shall be  conducted  as
provided in this Certificate of Incorporation, by law or in the Bylaws.

         NINTH:  The personal  liability of the Directors of the  Corporation is
hereby eliminated to the fullest extent permitted by the provisions of paragraph
(7) of subsection (b) of Section 102 of the General Corporation Law of the State
of Delaware, as the same may be amended and supplemented.

         TENTH:  The Corporation  shall, to the fullest extent  permitted by the
provisions  of  Section  145 of the  General  Corporation  Law of the  State  of
Delaware,  as the same may be amended and  supplemented,  indemnify  any and all
persons  whom it shall  have power to  indemnify  under  such  section  from and
against any and all of the expenses, liabilities or other matters referred to in
or covered by such section,  and the  indemnification  provided for herein shall
not be deemed  exclusive of any other rights to which those  indemnified  may be
entitled
                                       2
<PAGE>
under any Bylaw,  agreement,  vote of stockholders or Disinterested Directors or
otherwise,  both as to action in his or her official capacity and a to action in
another  capacity  while holding such office,  and shall continue as to a person
who has ceased to be a director,  officer,  employee or agent and shall inure to
the benefit of the heirs, executors and administrators of such a person.

         ELEVENTH:  From time to time any of the provisions of this  Certificate
of  Incorporation  may be amended,  altered or  repealed,  and other  provisions
authorized  by the laws of the  State of  Delaware  at the time in force  may be
added or inserted in the manner and at the time prescribed by such laws, and all
rights at any time conferred upon the  stockholders  of the  Corporation by this
Certificate  of  Incorporation  are granted  subject to the  provisions  of this
Article ELEVENTH.

         TWELFTH:  In case any  vacancy  shall  occur on the Board of  Directors
because  of  death,  resignation,  retirement,  disqualification,   removal,  an
increase in the authorized  number of Directors or any other cause, the Board of
Directors  shall have the sole and exclusive  authority  to, at any meeting,  by
resolution  adopted by the affirmative  vote of a majority of the Directors then
in office, though less than a quorum, elect a Director or Directors to fill such
vacancy  or  vacancies  until the next  election  of the  class  for which  such
Director or Directors shall have been chosen.

                  If, as a result of a disaster or emergency,  (as determined in
good faith by the then remaining Directors),  it becomes impossible to ascertain
whether or not  vacancies  exist on the Board of  Directors,  and a person is or
persons are elected by Directors,  who in good faith believe  themselves to be a
majority of the remaining  Directors,  to fill a vacancy or vacancies  that said
remaining  Directors in good faith believe exists,  then the acts of such person
or persons who are so elected as  Directors  shall be valid and binding upon the
Corporation and the stockholders,  although it may subsequently  develop that at
the time of the election (i) there was in fact no vacancy or vacancies  existing
on the Board of  Directors,  or (ii) the Directors who so elected such person or
persons did not in fact constitute a majority of the remaining Directors.

         THIRTEENTH:  Special  meetings of the  stockholders of the Corporation,
for any purpose or purposes,  unless otherwise  prescribed herein or by statute,
may be called by the Chairman of the Board and shall be called by the  Secretary
at the written request,  or by resolution  adopted by the affirmative vote, of a
majority  of the Board of  Directors.  Such  request  shall state the purpose or
purposes of the proposed  meeting.  Stockholders of the Corporation shall not be
entitled to request a special meeting of the stockholders.

         FOURTEENTH:  All  action by holders  of the  Corporation's  outstanding
voting  securities  shall  be taken  at an  annual  or  special  meeting  of the
stockholders following notice as provided by law or in the Bylaws.  Stockholders
of the Corporation shall not have the power to act by means of written consent.

         FIFTEENTH:  No person shall be elected to the Board of Directors of the
Corporation at an annual meeting of the  stockholders,  or at a special  meeting
called for that purpose, unless a written nomination of such person to the Board
of  Directors  by a  stockholder  of the  Corporation  shall be  received by the
Secretary of the Corporation at least sixty (60) days prior to such meeting.
                                       3
<PAGE>
         SIXTEENTH:  Notwithstanding  the fact that a lesser  percentage  may be
specified by law, the  affirmative  vote of the holders of  two-thirds  (2/3) of
each class of stock of the  Corporation  entitled  to vote shall be  required to
amend or repeal,  or adopt any provisions  inconsistent  with,  Article  FOURTH,
Article EIGHTH,  Article TWELFTH,  Article FOURTEENTH,  Article FIFTEENTH and/or
this Article SIXTEENTH of the Certificate of Incorporation;  provided,  however,
that the  provisions  of this Article  SIXTEENTH  shall not be applicable to any
amendment to the  Certificate of  Incorporation,  and such amendment  shall only
require such  affirmative  vote as required by law, if such amendment shall have
been  approved by a majority  of  Disinterested  Directors.  As used  herein,  a
"Disinterested  Director"  means  any  Director  of the  Corporation  who  was a
Director as of July 1, 1997, or was thereafter  elected by the  stockholders  or
appointed  by the Board of Directors of the  Corporation  and is not  associated
with or an affiliate of an  Interested  Stockholder  (as that term is defined in
this Article  SIXTEENTH)  directly or indirectly  involved in the transaction or
proposal  before the Board,  or a person  designated,  before his or her initial
election or appointment as a Director, as a Disinterested Director by a majority
of Disinterested Directors then on the Board.

                  As used herein,  Interested Stockholder shall mean any person,
firm,  corporation  or  other  entity  which,  as of the  record  date  for  the
determination  of  stockholders  entitled to notice of and to vote on any of the
above  transactions,  is the beneficial owner,  directly or indirectly,  of more
than five percent (5%) of any class of voting stock of the Corporation.  For the
purposes hereof, any person,  firm,  corporation or other entity shall be deemed
to be the  beneficial  owner of any  shares of voting  stock of the  Corporation
which (i) it has the right to acquire pursuant to any agreement or upon exercise
of conversion  rights,  warrants or options,  or  otherwise,  or (ii) are owned,
directly or indirectly (including shares deemed owned through the application of
clause (i) above), by any other person,  firm,  corporation or other entity with
which it has any  agreement,  arrangement or  understanding  with respect to the
acquisition,  holding,  voting or  disposition of stock of the  Corporation,  or
which is its  "affiliate" or "associate" as those terms are defined in the Rules
and Regulations under the Securities Exchange Act of 1934.

         IN WITNESS  WHEREOF,  the  undersigned  has  executed  this Amended and
Restated Certificate of Incorporation on the 19 day of November, 1997.

                                        MOBILE MINI, INC.

Exhibit 10.3
                                MOBILE MINI, INC.
                              AMENDED AND RESTATED
                             1994 STOCK OPTION PLAN
                     (as amended through November 12, 1997)


1.  PURPOSE OF PLAN.

         (a) General  Purpose.  The purpose of THE MOBILE MINI, INC. AMENDED AND
RESTATED  1994 STOCK OPTION PLAN  ("Plan") is to further the interests of Mobile
Mini, Inc., a Delaware  corporation (the  "Corporation") and its stockholders by
providing an incentive based form of  compensation  to the directors,  officers,
other key employees of the Corporation and providers of various  services to the
Corporation,  and by  encouraging  such  persons  to  invest  in  shares  of the
Corporation's  Common Stock,  thereby  acquiring a  proprietary  interest in its
business  and an  increased  personal  interest  in its  continued  success  and
progress and ongoing inducement to remain in the Corporation's employ.

         (b) Incentive  Stock Options.  Some one or more of the options  granted
under the Plan may be  intended  to qualify as an  "incentive  stock  option" as
defined in Section 422 of the  Internal  Revenue  Code of 1986,  as amended (the
"Code"),  and any grant of such an option shall clearly specify that such option
is intended to so qualify.  If no such  specification is made, an option granted
hereunder  shall be intended to not qualify as an "incentive  stock  option," as
previously defined.

         (c)  Adoption of and  Amendments  to the Plan.  The Plan was  initially
adopted by the Board of Directors of the  Corporation  (the  "Board") in August,
1994 and approved by the stockholders at the Corporation's  1994 annual meeting.
In July,  1996,  the Board  adopted an  amendment  to the Plan to increase  from
343,125 to 543,125 the number of shares of the Corporation's  common stock, $.01
par value (the "Common  Stock")  issuable  pursuant to options granted under the
Plan,  and the  stockholders  approved the amendment at the  Corporation's  1996
annual  meeting.  On July 1, 1997, the Board adopted  further  amendments to the
Plan,  including  amendments  (i)  increasing to 750,000 the number of shares of
Common  Stock  issuable  pursuant  to  options  granted  under  the  Plan,  (ii)
increasing  from 3,000 to 7,500 the number of shares of Common Stock  subject to
options granted  automatically  to non-employee  directors of the Corporation on
each August 1, commencing  August 1, 1997, and eliminating any limitation on the
aggregate   maximum   number  of  shares   that  could  be  subject  to  options
automatically  granted,  and (iii)  limiting to 150,000  the  maximum  number of
shares of Common  Stock  that may be  granted to any  salaried  employee  of the
Corporation  in any calendar year, in order to comply with Section 162(m) of the
Code. The amendments  were approved by the  stockholders on November 12, 1997 at
the Corporation's 1997 annual meeting. This document incorporates all amendments
to the Plan which have been approved by the Board and the  stockholders  through
November 12, 1997.

2. STOCK AND MAXIMUM NUMBER OF SHARES SUBJECT TO PLAN.

         (a)  Description  of Stock  and  Maximum  Shares  Allocated.  The stock
subject to the  provisions  of the Plan and  issuable  upon  exercise of options
granted under the Plan are shares of Common Stock, $.01 par value,  which may be
either  unissued  or  treasury  shares,  as the  Board  may  from  time  to time
determine. Subject to adjustments as provided in Section 7, the aggregate number
of shares of Common Stock  covered by the Plan and issuable upon exercise of all
options  granted  hereunder  shall be  750,000  shares,  which  shares  shall be
reserved  for use upon the  exercise of options to be granted from time to time.
Provided,  however, that in no event shall options to purchase more than 150,000
shares of Common Stock be granted to any salaried employee of the Company in any
one year.

         (b)  Restoration  of  Unpurchased  Shares.  If  an  option  expires  or
terminates  for any reason  prior to its exercise in full and before the term of
the Plan expires,  the shares subject to, but not issued under,  such option and
such shares shall again be available for other options thereafter granted.

3.  ADMINISTRATION; AMENDMENTS.

         (a) Administration by Committee.

                  (i) The Plan shall be  administered by a committee of not less
         than two  persons  that  also  serve on the  Board  (the  "Compensation
         Committee"),  with full power to administer  the Plan, to interpret the
         Plan  and  to  establish  and  amend  rules  and  regulations  for  its
         administration.  All members of the  Compensation  Committee shall not,
         during one year prior to service on the  Compensation  Committee,  have
         been granted or awarded any equity  securities of the Corporation or of
         any  affiliate  of the  Corporation,  or  during  such  service  on the
         Compensation   Committee  receive  a  grant  or  award  of  any  equity
         securities of the  Corporation or of any affiliate of the  Corporation,
         except  for  grants or awards  made (A)  prior to  registration  of the
         Corporation's  Common Stock under Section 12 of the Securities Exchange
         Act of 1934 or (B)  pursuant  to a plan which meets the  conditions  of
         Regulation ss.240.16b-3 of the Securities Exchange Act.

                  (ii) In accordance with Section  3(a)(i)(B)  above,  effective
         August 1, 1997 and on each August 1 thereafter  throughout  the term of
         this Plan, each of the members of the  Compensation  Committee and each
         other  Director  of the  Corporation  who is  not  an  employee  of the
         Corporation  shall be granted  an option to  purchase  7,500  shares of
         Common Stock at 100% of the fair market  value per share as  determined
         in Section 3(b) below, as of the date of such grant.  Such option shall
         vest and be  non-forfeitable  in the  amount  of 625  shares  per month
         commencing  on August 31 in the year of grant and in the  amount of 625
         shares on the last day of each  month  thereafter  provided  the person
         receiving such option  remains a member of the Board of Directors.  Any
         option  granted under this Section  3(a)(ii)  shall (A) be  exercisable
         immediately  in whole or in part upon the vesting  thereof,  (B) if not
         otherwise forfeited or terminated hereunder, expire if not
                                      -2-
<PAGE>
         exercised  prior  to  5:00  p.m.  Mountain  Standard  Time  on the  day
         preceding the tenth  anniversary of the effective date of grant of such
         option and (C) be subject to all terms and provisions of this Plan.

                  (iii)  In  lieu  of the  grant  of the  option  under  Section
         3(a)(ii),  a  member  of the  Compensation  Committee  may  elect to be
         compensated  in cash in the amount of $3,000 per  annum,  which  amount
         will be payable to such member of the  Compensation  Committee $250 per
         month  commencing  August  31,  1997 and on the last day of each  month
         thereafter  so long as such  person  remains  a member  of the Board of
         Directors.

         (b)  Exercise  Price.  Upon the grant of any option,  the  Compensation
Committee  shall  specify the exercise  price for the shares  issuable  upon its
exercise.  In no event may an option  exercise price per share be less than 100%
of the fair market value per share of the Corporation's Common Stock on the date
such option or right is granted.  Fair market value on any  particular day shall
be determined as follows:

                  (i) If the shares of Common  Stock are listed or  admitted  to
         trading on any securities exchange,  the fair market value shall be the
         closing sales price on such day on the New York Stock  Exchange on such
         other  securities  exchange  on  which  such  stock is then  listed  or
         admitted to trading,  or if no sale takes place on such day on any such
         exchange, on the next preceding day on which sales occur;

                  (ii) If the  shares  of Common  Stock  are not then  listed or
         admitted to trading on any securities  exchange,  the fair market value
         shall be the closing sales price on such day or, if no sale takes place
         on such day,  on the next  preceding  day on which  sales  occur in the
         over-the-counter  market as furnished by the  National  Association  of
         Securities Dealers Automated Quotations ("NASDAQ"), or if NASDAQ at the
         time is not  engaged in the  business  of  reporting  such  prices,  as
         furnished  by any  similar  firm  then  engaged  in such  business  and
         selected by the Board; or

                  (iii) If the  shares  of Common  Stock are not then  listed or
         admitted  to trading in the  over-the-counter  market,  the fair market
         value  shall  be  the  amount  determined  by  the  Board  in a  manner
         consistent with Treasury Regulation ss. 20.2031-2 promulgated under the
         Code or such other manner  prescribed  by the Secretary of the Treasury
         or the Internal Revenue Service.

         (c)   Interpretation.   The  interpretation  and  construction  by  the
Compensation  Committee  of the  terms  and  provisions  of this Plan and of the
agreements  governing  options and rights  granted under the Plan shall be final
and conclusive except for the grant of options or payment of cash to the members
of the Compensation Committee which shall be governed by the Board. No member of
the Compensation Committee shall be liable for any action taken or determination
made in good faith.
                                      -3-
<PAGE>
         (d) Amendments to Plan. The Compensation  Committee may, without action
on the part of the  stockholders  of the  Corporation,  make such amendments to,
changes in and additions to the Plan as it may,  from time to time,  deem proper
and in the best  interests of the  Corporation;  provided that the  Compensation
Committee may not,  without consent of the  optionholder,  take any action which
disqualifies  any option granted under the Plan as an incentive stock option for
treatment  as such or which  affects or impairs  the rights of the holder of any
option outstanding under the Plan, and further provided that, except as provided
in Section  7, the Board may not,  without  the  approval  of the  Corporation's
stockholders,  (i)  increase  the  aggregate  number of  shares of Common  Stock
subject  to the Plan,  (ii)  change  the class of  persons  eligible  to receive
options,  (iii)  modify the period  within  which  options may be granted,  (iv)
modify the period within which options may be exercised,  the exercise  price or
the terms upon which  options may be  exercised,  or (iv)  increase the material
benefits accruing to participants under the Plan.

         (e) Ratification By Compensation  Committee.  The Board may act in lieu
of  the  Compensation  Committee  in  administering,   granting  options  under,
construing and interpreting the Plan contingent upon and subject to ratification
by the Compensation Committee.

4.  PARTICIPANTS; DURATION OF PLAN.

         (a) Eligibility and Participation.  Options may be granted in the total
amount for the period as  allocated  by the Board as  provided  in Section  4(b)
below  only to persons  who at the time of grant are  directors,  key  executive
employees,  key  managerial  employees,  or  key  supervisory  employees  of the
Corporation or to such other persons which provide  services to the  Corporation
as determined by the Board,  whether or not such persons are also members of the
Board;  provided,  however,  that no incentive  stock option may be granted to a
director of the Corporation unless such person is also a key executive employee,
key managerial employee, or key supervisory employee of the Corporation.

         (b) Allotment. The Board shall determine the aggregate number of shares
of Common  Stock  which may be optioned  from time to time but the  Compensation
Committee  shall have sole  authority to determine  the number of shares and the
recipient  thereof to be optioned at any time. The Compensation  Committee shall
not be required to grant all options allocated by the Board for any given period
if it determines,  in its sole and exclusive judgment, that such grant is not in
the best  interests  of the  Corporation.  The grant of an option to any  person
shall neither entitle such  individual to, nor disqualify such individual  from,
participation in any other grant of options under the Plan.

         (c)  Duration  of  Plan.  The  term  of  the  Plan,  unless  previously
terminated by the Board, is ten years  commencing on the date of adoption of the
Plan by the Board.  No option  shall be granted  under the Plan  unless  granted
within  ten  years  of the  adoption  of the  Plan  by the  Board,  but  options
outstanding on that date shall not be terminated or otherwise affected by virtue
of the Plan's expiration.
                                      -4-

5.  TERMS AND CONDITIONS OF OPTIONS AND RIGHTS.

         (a)  Individual  Agreements.  Options  granted  under the Plan shall be
evidenced by  agreements  in such form as the Board from time to time  approves,
which agreements shall substantially  comply with and be subject to the terms of
the Plan, including the terms and conditions of this Section 5.

         (b)  Required  Provisions.  Each  agreement  shall  state (i) the total
number of shares to which it pertains,  (ii) the  exercise  price for the shares
covered by the option,  (iii) the time at which the option becomes  exercisable,
(iv) the scheduled  expiration date of the option, (v) the vesting period(s) for
such options, and (vi) the timing and conditions of issuance of any stock option
exercise.

         (c) Period. No option granted under the Plan shall be exercisable for a
period in excess of ten years  from the date of its  grant,  subject  to earlier
termination in the event of  termination  of employment,  retirement or death of
the holder as  provided  in Section 6 or  otherwise  set forth in the  agreement
granting  the option.  An option may be exercised in full or in part any time or
from time to time during the term thereof, or provide for its exercise in stated
installments at stated times during such term.

         (d) No Fractional Shares. Options shall be granted and exercisable only
for whole  shares;  no  fractional  shares will be issuable upon exercise of any
option granted under the Plan.

         (e) Method of Exercising Option.  Options shall be exercised by written
notice to the  Corporation,  addressed to the Corporation at its principal place
of business. Such notice shall state the election to exercise the option and the
number of  shares  with  respect  to which it is being  exercised,  and shall be
signed by the person exercising the option. Such notice shall be accompanied (i)
by the certificate  described in Section 8(b) and (ii) by payment in full of the
exercise price for the number of shares being purchased.  Payment may be made in
cash or by bank cashier's check or by tendering duly endorsed  certificates  for
shares of the  Corporation's  Common Stock then owned by the  optionholder.  The
Corporation shall deliver a certificate or certificates  representing the option
shares to the  purchaser as soon as  practicable  after payment for those shares
has been  received.  If an option is  exercised  pursuant to Section 6(c) by any
person  other  than  the  optionholder,  such  notice  shall be  accompanied  by
appropriate proof of the right of such person to exercise the option. All shares
that are  purchased and paid for in full upon the exercise of an option shall be
fully paid and non-assessable.

         (f) No Rights of a Stockholder. An optionholder shall have no rights as
a stockholder with respect to shares covered by an option. No adjustment will be
made for dividends  with respect to an option for which the record date is prior
to the date a stock  certificate  is issued  upon  exercise  of an option.  Upon
exercise  of an option,  the holder of the  shares of Common  Stock so  received
shall  have all rights of a  stockholder  of the  Corporation  as of the date of
issuance.

         (g) Compliance with Law. No shares of Corporation Common Stock shall be
issued or  transferred  upon the  exercise  of any  option  unless and until the
following occurs:
                                      -5-
<PAGE>
                  (i)All  legal  requirements  applicable  to  the  issuance  or
         transfer of such shares have been complied with; and

                  (ii) All requirements of any national  securities  exchange or
         association  upon which the shares are  listed,  traded or quoted  have
         been met, in each case to the satisfaction of the Board and free of any
         conditions unacceptable to the Compensation Committee. The Compensation
         Committee  shall have the right to condition the issuance of any shares
         made to any person hereunder on such person's undertaking in writing to
         comply with such  restrictions on his or her subsequent  disposition of
         such  shares as the  Compensation  Committee  shall deem  necessary  or
         advisable as a result of any  applicable  law,  regulation  or official
         interpretation  thereof, and a legend may be placed on the certificates
         representing such shares to reflect any such restriction.

         (b) Other  Provisions.  The option  agreements  may contain  such other
provisions as the Board deems  necessary to effectuate  the sense and purpose of
the Plan,  including  covenants on the holder's part not to compete and remedies
to the Corporation in the event of the breach of any such covenant.

6.  TERMINATION OF EMPLOYMENT; ASSIGNABILITY; DEATH.

         (a)  Termination  of  Employment.  If any  optionholder  ceases to be a
director or employee of the Corporation,  or ceases to render services  pursuant
to a consulting, management or other agreement, other than for death, disability
or  discharge  for  cause,  such  holder (or its  successors  in the case of the
holder's death after the termination of employment or directorship)  may, within
three  months  after the date of  termination,  but in no event after the stated
expiration  date of the option,  purchase some or all of the shares with respect
to which such  optionholder was entitled to exercise such option or exercise the
rights  which such holder  held,  on the date such  employment  or  directorship
terminated  and the  option  shall  thereafter  be void  for all  purposes.  Any
termination  of an  agreement  pursuant to which  services  are  rendered to the
Corporation  by any party  who is an  optionholder,  without  a renewal  of that
agreement  or entry  into a similar  successor  agreement,  may be  treated as a
termination of the employment of the third party.

         (b)  Assignability.  No option granted under the Plan or the privileges
conferred  thereby shall be assignable or transferable by a holder other than by
will  or the  laws of  descent  and  distribution,  and  such  option  shall  be
exercisable by such holder during the lifetime of the holder only.

         (c) Disability.  If the employment or directorship of the  optionholder
is terminated due to disability,  the optionholder may exercise the options,  in
whole or in part,  to the  extent  they  were  exercisable  on the date when the
optionholder's  employment or directorship terminated,  at any time prior to the
expiration  date of the options or within one year of the date of termination of
employment or directorship, whichever is earlier.
                                      -6-
<PAGE>
         (d)  Discharge for Cause.  If the  employment  or  directorship  of the
optionholder  with the Corporation is terminated due to discharge for cause, the
options  shall  terminate  upon  receipt by the  optionholder  of notice of such
termination  or the  effective  date of the  termination,  whichever is earlier.
Discharge for cause shall include  discharge  for personal  dishonesty,  willful
misconduct in performance of duties, failure, impairment or inability to perform
required  duties,  inefficiencies  or omissions in performing  required  duties,
breach  of  fiduciary  duty or  conviction  of any  felony  or  crime  of  moral
turpitude. The Compensation Committee shall have the sole and exclusive right to
determine whether the optionholder has been discharged for cause for purposes of
the Plan and the date of such discharge.

         (e) Death of Holder. If an optionholder dies while in the Corporation's
employ,  an option shall be exercisable until the stated expiration date thereof
by the person or persons  ("successors")  to whom the holder's rights pass under
will or by the laws of descent and distribution, but only to the extent that the
holder was entitled to exercise  the option at the date of death.  An option may
be exercised  (and  payment of the option price made in full) by the  successors
only after written notice to the Corporation, specifying the number of shares to
be  purchased  or rights to be  exercised.  Such  notice  shall  comply with the
provisions of Section 5(e), and shall be accompanied by the certificate required
by Section 8(b).

7.  CERTAIN ADJUSTMENTS.

         (a) Capital Adjustments.  Except as limited by Section 422 of the code,
the aggregate  number of shares of Common Stock subject to the Plan,  the number
of shares covered by outstanding options, and the price per share stated in such
options  shall be  proportionately  adjusted for any increase or decrease in the
number of outstanding shares of Common Stock of the Corporation resulting from a
subdivision or  consolidation  of shares or any other capital  adjustment or the
payment of a stock  dividend or any other  increase or decrease in the number of
such  shares  effected  without  receipt  by the  Corporation  of  consideration
therefor in money, services or property.

         (b) Mergers, Etc. Except as limited by the provisions of Section 422 of
the Code,  if the  Corporation  is the  surviving  corporation  in any merger or
consolidation,  any option  granted under the Plan shall pertain to and apply to
the securities to which a holder of the number of shares of Common Stock subject
to the option would have been  entitled.  A dissolution  or  liquidation  of the
Corporation shall cause every option outstanding hereunder to terminate,  unless
specifically provided otherwise by the Board. A merger or consolidation in which
the Corporation is not the surviving  corporation  shall also cause every option
outstanding  hereunder to terminate,  unless specifically  provided otherwise by
the Board, but each holder shall have the right immediately prior to a merger or
consolidation  in which the  Corporation  is not the surviving  corporation,  to
exercise  such  option  in  whole  or in  part  without  regard  to any  vesting
requirements  or  installment  provisions  contained  in the  option  agreement;
provided  that if the  number  of  shares  qualified  as being  issued  under an
incentive  stock option plan at a similar  price is afforded a holder under this
Plan, subject to proportional adjustment pursuant to the merger or consolidation
agreement,  then such  incentive  stock options  outstanding  hereunder may, but
shall not be required to, be terminated.

8.  DELIVERY OF STOCK; LEGENDS; REPRESENTATIONS.

         (a) Legend on  Certificates.  All certificates  representing  shares of
Common Stock  issued upon  exercise of options  granted  under the Plan shall be
endorsed with a legend reading as follows:

                           The  shares  of  Common   Stock   evidenced  by  this
                  certificate  have  been  issued  to the  registered  owner  in
                  reliance upon written  representations  that these shares have
                  been purchased solely for investment.  These shares may not be
                  sold,  transferred  or  assigned  unless in the  option of the
                  Corporation  and its legal  counsel  such  sale,  transfer  or
                  assignment  will not be in violation of the  Securities Act of
                  1933, as amended, and the Rules and Regulations thereunder.

         (b) Private  Offering for Investment Only. The options are and shall be
made available only to a limited number of present and future key executives and
key  employees  who have  knowledge of the  Corporation's  financial  condition,
management  and its  affairs.  The Plan is not  intended  to provide  additional
capital  for  the  Corporation,  but to  encourage  stock  ownership  among  the
Corporation's  key  personnel.   By  the  act  of  accepting  an  option,   each
optionholder agrees (i) that, if he or his successors exercise his option, he or
his  successors  will purchase the subject  shares solely for investment and not
with any intention at such time to resell or redistribute those shares, and (ii)
that  he or  his  successors  will  confirm  such  intention  by an  appropriate
certificate at the time the option is exercised. However, the neglect or failure
to execute such a certificate shall not limit or negate the foregoing agreement.

         (c) Registration  Statement.  If a Registration  Statement covering the
shares of Common Stock  issuable upon the exercise of options  granted under the
Plan is filed under the  Securities  Act of 1933,  as  amended,  and is declared
effective by the Securities and Exchange  Commission,  the provisions of Section
8(a)  relating to  endorsement  of a  restrictive  legend and the  provisions of
Securities  8(b) relating to investment  covenants  shall  terminate  during the
period  that  the  Registration  Statement,  as  periodically  amended,  remains
effective.

9.  APPLICATION OF FUNDS.


         The proceeds  received by the Corporation from the sale of Common Stock
pursuant to the exercise of options will be used for general corporate purposes.

                           SECOND AMENDMENT TO LEASE


         THIS SECOND  AMENDMENT  TO LEASE (the "Second  Amendment")  amends that
certain  Lease  entered  into as of January 1, 1994 by and between  Landlord and
Tenant  related  to the  Premises  located  at  2660  North  Locust  in  Rialto,
California,  as previously amended by an Amendment to Lease, dated as of January
1,  1994  (the  Lease  and  Amendment  to Lease  are  collectively  referred  to
hereinafter as the "Original  Lease").  Unless specified to the contrary herein,
all capitalized terms in this Second Amendment shall have the meanings set forth
for such terms in the Original  Lease.  The terms of this Second  Amendment  are
incorporated  into  and  shall  be  effective  as of the  effective  date of the
Original Lease.

         1.       Section 1.3 is amended in its entirety to read as follows:

                  1.3 Term.  The term of this Lease shall commence on January 1,
                  1994  (the  "Commencement  Date")  and  shall  expire,  unless
                  extended as provided in Section 3.3 on April 1, 2011.

         2.       Attachment  "A" is deleted in its entirety  and replaced  with
                  Attachment "A" hereto.

         3.       Except as  amended  herein,  the terms of the  Original  Lease
                  shall  remain in full  force and  effect and the terms of this
                  Second  Amendment  and the  Original  Lease as amended  hereby
                  shall  bind,  extend  to  and  inure  to  the  benefit  of the
                  respective  heirs,  legal  representatives  and successors and
                  assigns of both Landlord and Tenant;  provided, however,  that
                  this paragraph  shall not permit any transfer  contrary to the
                  provisions of Article 20 of the Original Lease.

         IN WITNESS WHEREOF, the parties have duly executed the Second Amendment
as of the 1st day of June 1996.
