                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information and the financial statements and notes included elsewhere in this
Prospectus or incorporated by reference herein. Unless otherwise indicated, all
information in this Prospectus assumes that the Underwriters' over-allotment

                                  THE COMPANY
 
     SOS Staffing Services, Inc. ("SOS" or the "Company") is a leading provider
of staffing services in the western United States. SOS currently operates a
network of 116 offices in 16 states. The Company provides a broad range of
commercial staffing and information technology ("IT") services. Commercial
staffing services include light industrial, clerical, industrial, technical and
other professional services. IT services consist of staffing, consulting and
outsourcing services such as systems design, programming, network and systems
management and business consulting. During the 26 weeks ended June 29, 1997, the
Company provided approximately 41,000 staffing employees to more than 6,400
businesses, professional and service organizations and government agencies.
 
     The staffing industry, which, according to the National Association of
Temporary and Staffing Services ("NATSS"), reported a compound annual payroll
growth rate of approximately 15% between 1991 and 1996, continues to benefit
from increased competitive pressures on businesses to reduce costs. In recent
years, businesses have increasingly used staffing service personnel as a
strategy for converting fixed labor costs to flexible, manageable costs and for
meeting specialized or fluctuating employment requirements. According to NATSS,
in 1996, the average number of daily staffing employees as a percentage of total
U.S. employment reached approximately 1.9%, up from 0.9% in 1989.
 
     The Company has benefitted significantly from strong economic and
population growth in the Mountain States (Utah, Colorado, Idaho, Wyoming,
Arizona, Nevada, New Mexico and Montana) and improving economic conditions in
certain other western states. The Regional Financial Review projects that, in
1998, non-farm employment in the Mountain States will increase by 3.0%, compared
to a national average of 1.2%. Management believes the attraction of the
Mountain States results from the region's economic growth, diverse economic
base, productive work force and high quality of life. Management believes the
economic strength and projected job growth in the western states will support
the Company's anticipated growth and enable the Company to pursue additional
growth opportunities.
 
     The Company's growth strategy for commercial staffing services is to
further penetrate existing markets and expand into new markets in the western
states by opening new offices and expanding the range of staffing services
offered to its customers. A key element of this strategy is the establishment of
hub offices in key population areas followed by the clustering of additional
offices in existing and surrounding markets. During the last five years, the
Company has maintained an average annual internal revenue growth rate in excess
of 20%.
 
     The Company's growth strategy also includes continued acquisition of
commercial staffing and IT staffing and consulting offices in the western
states. Since completing its initial public offering ("IPO") in July 1995, the
Company has acquired 30 staffing companies with 42 offices, consisting of 28
commercial staffing offices and 14 IT staffing and consulting offices. Since
July 1996, the Company has acquired nine IT staffing and consulting companies,
allowing the Company to diversify the mix of staffing services provided to
include higher margin services. On a pro forma basis, revenues from IT staffing
services represented 25% of total revenues for the 26 weeks ended June 29, 1997.
Additional acquisitions have added other specialty services, including medical
administrative support, professional mining, geology, hydrology and
environmental services. See "Unaudited Pro Forma Condensed Consolidated
Financial Data" and "Business -- Recent and Pending Acquisitions."
 
     The Company's business strategy is designed to enhance its overall
profitability. The Company targets small to medium-sized customers in order to
reduce its exposure to margin pressure often associated with large national
accounts. The Company also focuses on delivering higher margin services, such as
IT staffing and consulting and other specialty staffing services. The Company
currently offers a broad range of staffing and consulting services and
continually looks for opportunities to enhance its service offerings. The
Company also encourages entrepreneurial spirit and customer service orientation
in its field management, largely through operating flexibility coupled with
performance incentives. Furthermore, the Company emphasizes service and value in
order to establish and maintain long-term relationships with its clients.

                                  RISK FACTORS
 
     The Common Stock being offered hereby involves a high degree of risk.
Prospective purchasers of the Common Stock offered hereby should carefully
consider the following risk factors, as well as the other information contained
in this Prospectus or incorporated by reference herein.
 
RISKS OF GROWTH STRATEGY
 
     The Company has experienced significant growth in the past, primarily
through acquisitions, growth of existing offices and the opening of new offices.
The Company's continued growth is dependent upon a number of factors, including
the availability of working capital to support such growth; the Company's
response to existing and emerging competition; the Company's ability to maintain
sufficient profit margins in the face of pricing pressures; the Company's
efforts to successfully develop and maintain customer and employee
relationships; and the successful hiring, training and retention of qualified
field management. Expansion beyond the geographic areas where offices are
presently located will increase demands on the Company's management. As the
Company continues to grow, there is no assurance that historical rates of
internal growth can be sustained. The Company could also experience unexpected
delays or other problems with respect to the opening of new offices. Any
significant delay in the opening of new offices or the failure of new offices to
achieve anticipated performance levels could adversely impact the Company's
operations and expansion plans. See "Business -- Growth Strategy."
 
ACQUISITION RISKS
 
     The Company's growth strategy includes expansion through the acquisition of
staffing service companies. The Company must, however, compete for acquisitions
with numerous other staffing companies that have significantly greater financial
resources than the Company. Competition for acquisitions has become increasingly
intense since other staffing companies have begun seeking to increase their
market share. As the Company attempts to expand into new geographic areas and
targets acquisitions of larger companies offering higher margin specialized
services, the Company will likely encounter increased competition for
acquisition opportunities. If the Company is successful in locating and
acquiring businesses in larger metropolitan areas, of which there can be no
assurance, the Company may be required to pay higher purchase prices.
Accordingly, there can be no assurance that the Company will be able to acquire
targeted businesses on terms favorable to the Company, or at all. The
acquisition of additional business operations and the subsequent integration of
such acquisitions could result in significant costs and expenses to the Company,
interrupt the Company's operations, place additional burdens on the Company's
management, systems and controls and divert the attention of management from the
ongoing operations of the Company, particularly in the fiscal quarters
immediately following the consummation of such transactions. Further, there can
be no assurance that any particular acquisition will be successfully integrated
into the Company's operations or will maintain profitability. In addition,
acquisitions by the Company could involve the incurrence of additional debt,
future amortization or impairment of goodwill and other intangible assets or the
issuance of equity securities having a
dilutive effect, all of which could adversely affect the Company's operating or
financial results. See "Business -- Growth Strategy."
 
DEPENDENCE ON KEY MANAGEMENT
 
     The Company recently announced changes in its senior management, including
the appointment of Howard W. Scott as Chief Executive Officer, Peter R. Sollenne
as President and Chief Operating Officer and JoAnn W. Wagner as Vice Chairman of
the Board and Executive Vice President of Corporate Development. The changes
reflect the decision of Richard D. Reinhold, founder, Chairman of the Board and
former Chief Executive Officer of the Company, to substantially decrease his
day-to-day involvement in the Company's operations, which may have an adverse
effect on the Company's operations. The Company has been and continues to be
highly dependent on its senior managers and on its ability to hire, develop and
retain qualified field managers, as well as on the productivity of its managers.
The Company has entered into confidentiality and limited non-solicitation
agreements with its managers; however, there can be no assurance that such
agreements will be enforceable in all jurisdictions or for the periods set forth
therein, or that the Company
 
                                        6
<PAGE>   7
 
would not incur significant expense attempting to enforce such agreements. The
loss of senior management or other key employees or the inability of the Company
to attract and retain qualified field management could have a material adverse
effect on the Company's operations. See "Management."
 
IT BUSINESS RISKS
 
     Businesses have increasingly utilized IT services to support their IT
operations in order to keep pace with the rapid technological advances in
business information systems. The Company's efforts to expand its staffing
services to include IT staffing and consulting may be adversely affected by the
Company's limited prior experience in providing such services and is dependent
on its ability to effectively identify, acquire and integrate IT staffing and
consulting operations, to recruit and retain qualified IT personnel and to
successfully market IT staffing and consulting services. The Company's lack of
prior IT experience or failure to operate its IT business profitably could have
a material adverse effect on the Company's business, financial condition or
results of operations.
 
COMPETITION
 
     The staffing industry is highly competitive and fragmented, and there are
limited barriers to entry. The Company competes with national, regional and
local full-service and specialized staffing services companies, some of which
have significantly greater marketing and financial resources than the Company.
The Company competes with these staffing companies in its efforts to recruit and
develop a base of qualified personnel within a geographic market. As the Company
pursues its growth strategy of internal growth and growth through acquisitions,
its success will depend in part on its ability to gain market share from
competitors and to develop new markets for its services. The Company expects
that the level of competition will remain high, and there can be no assurance
that the Company will not encounter increased competition in the future. In
particular, the Company believes the developing practice of large national and
regional companies to make centralized purchasing decisions for staffing
services on a national or regional basis will increase competition in certain
market segments. Continued or increased competition could limit the Company's
ability to maintain or increase its market share and maintain its existing
margins and could have a material adverse effect on the Company's business,
financial condition or results of operations. See "Business -- Competition."
 
RISK OF ECONOMIC FLUCTUATIONS
 
     The staffing services industry is affected, to a large extent, by trends in
national, regional or local economic conditions. During periods of slowing
economic activity or high unemployment, many companies reduce their usage of
staffing employees before laying off regular employees. In addition, the Company
may face increased pricing pressure during economic downturns. A substantial
majority of the Company's revenues are presently derived from its operations in
the Mountain States. A deterioration in economic conditions in the markets where
the Company operates could materially adversely affect the Company's business,
financial condition and results of operations. There can be no assurance that
future economic downturns will not have a material adverse effect on the
Company's performance. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Seasonality."
 
EMPLOYEE-RELATED COSTS
 
     The Company is responsible for employee-related expenses for its staff
employees, including workers' compensation and unemployment insurance. The
Company maintains workers' compensation insurance for all claims in excess of a
loss cap of $200,000 per incident, except with respect to certain divisions
which are covered by state insurance funds in states where private insurance is
not permitted. The Company maintains a reserve for the estimated costs of
workers' compensation claims based on the Company's prior experience and
information provided by the Company's insurer. Management believes that the
established reserve for workers' compensation obligations is adequate, but there
can be no assurance that the actual cost of such workers' compensation
obligations will not exceed the established reserve. In addition, the Company
may incur higher workers' compensation costs in the future due to higher than
anticipated losses from known claims, an increase in the number and severity of
new claims, an increase in the cost of workers' compensation
 
                                        7
<PAGE>   8
 
insurance or changes in workers' compensation laws. Unemployment insurance
premiums are set by the states in which the Company's staff employees render
their services, and may be increased by such states at any time. A significant
increase in employee-related costs could have a material adverse effect on the
Company's operating results. See "Business -- Operations -- Risk Management
Program."
 
AVAILABILITY OF QUALIFIED STAFFING PERSONNEL
 
     The Company competes with other staffing companies, as well as Company
customers and other employers, for qualified personnel. In addition, a
substantial number of the Company's staffing employees during any given year
will terminate employment with the Company to accept employment with Company
customers. The Company may in the future encounter difficulty in recruiting
sufficient staffing employees of the caliber the Company is committed to provide
to its customers. In particular, the Company may have difficulty recruiting and
retaining qualified personnel in the specialized staffing and consulting areas,
such as the IT sector. In addition, during periods of higher employment, the
Company may incur increased expenses associated with recruiting qualified
staffing employees. The Company believes there is a shortage of, and significant
competition for, IT professionals who possess the technical skills and expertise
necessary to deliver the Company's IT services and that such IT professionals
are likely to remain a limited resource for the foreseeable future. An inability
to attract and retain a sufficient number of additional qualified staffing
employees to support the Company's planned growth, or the loss of a significant
number of qualified staffing employees, could adversely affect the Company's
operating results and business strategy. See "Business --
Operations -- Recruiting."
 
STAFFING EMPLOYMENT RISKS
 
     The Company's staffing employees are typically employed in the workplace of
the Company's customers. Accordingly, the Company is exposed to potential
liability in respect to any claims arising out of the services performed by the
Company's staffing employees, such as misuse of client information or theft of
client property. In addition, the Company has exposure to potential claims by
its staffing employees of discrimination and harassment in the customer's
workplace and other similar claims. As an employer, the Company is also exposed
to claims resulting from the violation of other employment-related laws and
regulations, as well as violations of immigration laws. Because the Company
estimates that it will employ more than 70,000 staffing employees during 1997,
as well as more than 600 staff employees, the Company's exposure to employment-
related claims may be significantly greater than comparably-sized employers in
other industries. Claims arising under employment-related laws or regulations or
the failure of Company employees to follow Company policies and guidelines may
result in negative publicity, injunctive relief or the payment by the Company of
monetary damages or fines, which could have a material adverse effect on the
Company's operating results and financial condition.
 
QUARTERLY VARIATIONS IN RESULTS
 
     The Company believes that comparisons of its quarterly financial results
are not necessarily meaningful and should not be relied upon as an indication of
future performance trends. The Company's business follows the seasonal trends of
its customers' businesses which are, in turn, affected by, among other things,
the climates in the states in which the customers operate. Historically, the
Company has experienced higher revenues in the third quarter and lower revenues
in the first quarter due to unfavorable weather conditions and lower overall
economic activity. The timing of acquisitions may also result in variations in
quarterly results. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Quarterly Results of Operations" and
"-- Seasonality."
 
CONCENTRATION OF OWNERSHIP
 
     Following this offering, Richard D. Reinhold, the Company's Chairman of the
Board, and Sandra E. Reinhold, his wife, will control the vote of approximately
23.5% of the outstanding shares of the Common Stock. As a result, they will have
the ability to influence the election of all the Company's directors and the
outcome of issues submitted to the Company's shareholders. Future sales by Mr.
and Mrs. Reinhold of
 
                                        8
<PAGE>   9
 
substantial amounts of Common Stock, or the potential for such sales, could
adversely affect the prevailing market price for the Common Stock. See
"Principal and Selling Shareholders."
 
LEGAL PROCEEDINGS
 
     The Company is always subject to the risk that it may be a party to legal
proceedings. The staffing industry is subject in particular to potential
liability to customers arising in connection with the services performed by the
Company's staffing employees, and claims of staffing employees relating to the
customers' workplaces. The defense of litigation could result in substantial
expense for the Company and divert the attention of management from the
operations of the Company, which could have an adverse effect on the Company's
business, financial condition and results of operations. Moreover, there can be
no assurance that the Company will prevail in such litigation. See "-- Staffing
Employment Risks" and "Business -- Legal and Administrative Proceedings."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of substantial amounts of shares in the public market following this
offering could adversely affect the market price of the Common Stock. Upon
completion of this offering, the Company will have 12,052,852 shares of Common
Stock outstanding. Of these shares, 9,217,352 shares, including the 4,000,000
shares sold in this offering, will generally be freely tradeable without
restriction. In addition, 2,835,500 shares of Common Stock are tradeable
pursuant to provisions of Rule 144 under the Securities Act. Under lock-up
agreements with the Underwriters, certain shareholders, owning 2,835,500 shares
in the aggregate after the offering, have agreed that they will not, without the
prior written consent of Lehman Brothers Inc., offer, sell, contract to sell, or
otherwise dispose of any shares of Common Stock beneficially owned by them for a
period of 180 days after the effective date of the Registration Statement of
which this Prospectus forms a part. See "Underwriting."
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
     The Common Stock has been quoted on the Nasdaq National Market since June
1995 and its trading price has fluctuated over a broad range. Prior to that
time, there was no public market for the Common Stock. The trading price of the
Common Stock could continue to fluctuate widely in response to variations in
quarterly operating and financial results, announcements by the Company or its
competitors, industry trends, legislative or regulatory changes, general
economic conditions or other events or factors. See "Price Range of Common
Stock."
 
ANTI-TAKEOVER CONSIDERATIONS
 
     The Company's Amended and Restated Articles of Incorporation and Amended
and Restated Bylaws and the Utah Revised Business Corporation Act contain
certain provisions that may have the effect of deterring a non-negotiated merger
or other business combination. The Board of Directors of the Company will have
the authority, without further action by the Company's shareholders, to fix the
rights and preferences, and issue shares, of the Company's Preferred Stock.
These provisions, and other provisions of the Company's Amended and Restated
Articles of Incorporation, may have the effect of deterring hostile takeovers or
delaying or preventing changes in control or management of the Company,
including transactions in which shareholders might otherwise receive a premium
for their shares over the then-current market prices. These provisions may limit
the ability of shareholders to approve transactions that they may deem to be in
their best interests. In addition, the ownership of 23.5% of the Common Stock by
the Company's Chairman of the Board and his wife could prevent or delay changes
in control or management of the Company. See "-- Concentration of Ownership."
 
FORWARD-LOOKING INFORMATION
 
     This Prospectus contains various forward-looking statements and information
that are based on management's belief, as well as assumptions made by and
information currently available to management. When used
 
                                        9
<PAGE>   10
 
in this document, the words "anticipate," "estimate," "project," "expect," and
similar expressions are intended to identify forward-looking statements.
Although the Company believes that the expectations reflected in such
forward-looking statements are reasonable, it can give no assurance that such
expectations will prove to have been correct. Such statements are subject to
certain risks, uncertainties and assumptions. Should one or more of these risks
or uncertainties materialize, or should underlying assumptions prove incorrect,
actual results may vary materially from those anticipated, estimated, projected
or expected. Among the key factors that may have a direct bearing on the
Company's operating results are fluctuations in the economy, the degree and
nature of competition, demand for the Company's services, and the Company's
ability to integrate the operations of acquired businesses, to recruit and place
staffing employees, to expand into new markets, and to maintain profit margins
in the face of pricing pressures.

                                  THE COMPANY
 
     SOS was organized in Utah in 1973, initially doing business as SOS
Employment Services and subsequently as SOS Temporary Services. The Company's
corporate name was changed in fiscal 1995 to SOS Staffing Services, Inc.,
reflecting the diversity of staffing services the Company offers.
 
     The Company is a leading provider of staffing services in the western
states. SOS currently operates a network of 116 offices located in 16 states.
The Company provides a broad range of commercial staffing and IT services.
Commercial staffing services include light industrial, clerical, industrial,
technical and other professional services. IT services consist of staffing,
consulting and outsourcing services, such as systems design, programming,
network and systems management and business consulting.
 
     The Company offers commercial and specialty staffing services primarily
through the Company's SOS Staffing Services(R) offices. The Company also offers
commercial and specialty staffing services under service-specific names in
various markets where market size permits diversification, including Skill Staff
(construction and manufacturing services), Industrial Specialists (warehousing
and labor services and trucking), AccountStaff (accounting and financial
services), SOS Technical Services (engineering, programming, design and other
technical services), ServCom Management Services (professional employer
services), PAMS (medical administrative support services) and CGS Personnel,
Inc. (mining, mineral exploration and environmental professional services). The
Company offers IT staffing, consulting and outsourcing services under the names
Wolfe & Associates, Inc., The Performance Group, Impact Staffing, Computer
Group, Inc., The Solution Team, Inc., Telecom Project Assistance, Inc., Bedford
Consultants, Inc., Execusoft, Inc. and JesCo Technical Services, Inc.; however,
as the Company integrates acquired IT companies into its consolidated IT
operations, the Company plans to adopt common business names for use throughout
the Company's IT network.
 
     Since completing its IPO in July 1995, the Company has acquired 30 staffing
companies, 21 of which were commercial and specialty staffing businesses and
nine of which were IT staffing and consulting businesses. These acquisitions
have enabled the Company to expand its geographic base, as well as the breadth
of services it offers to its customers. The Company has also announced execution
of an agreement to acquire an additional staffing company. See
"Business -- General," "-- Recent and Pending Acquisitions" and "-- Growth
Strategy."
 
     Unless the context otherwise indicates, all references to SOS or the
Company in this Prospectus include the offices or businesses operating under the
names set forth above. The Company's principal executive offices are located at
1415 South Main Street, Salt Lake City, Utah 84115 and its telephone number is
(801) 484-4400.
 
                              RECENT DEVELOPMENTS
PROPOSED CENTURY ACQUISITION
 
     On October 1, 1997, the Company entered into an Asset Purchase Agreement
(the "Century Agreement") among the Company, Century Personnel, Inc., which does
business as The Century Group and Centech, M.A. Jones Enterprises, Inc.
(collectively, "Century") and Michael A. Jones, the sole shareholder of Century.
The Century Agreement provides for, among other things, the Company's
acquisition of substantially all of the assets of Century (the "Century
Acquisition"). Century, based in Overland Park, Kansas, provides commercial and
IT staffing services through 13 offices in Kansas and Missouri. Century's
business consists principally of providing commercial staffing services. The
consummation of the Century Acquisition is subject to the approval of the U.S.
Federal Trade Commission and the U.S. Department of Justice. The Company
currently anticipates that the Century Acquisition will be consummated in
November 1997. The Company believes that the Century Acquisition, if
consummated, will provide the Company with additional growth opportunities in
the midwestern region of the United States.
 
     The purchase price to be paid by the Company consists of an initial
purchase payment of approximately $14.9 million and two earnout payments payable
within 45 days of each of the first and second anniversaries of the closing date
of the Century Acquisition. The amount of the initial purchase payment is
subject to reduction in the event an audit of Century's financial statements
results in adjustments to the financial statements provided to the Company at
the time of execution of the Century Agreement. The Company
 
                                       11
<PAGE>   12
 
intends to use a portion of the proceeds of this offering, if completed, to pay
the initial purchase payment. The amounts of the earnout payments will be based
upon the earnings before interest and taxes generated by Century's business
operations during the two one-year periods following the closing. The Century
Agreement provides that the aggregate purchase price payable by the Company
shall not exceed $25 million.
 
     In connection with the Century Acquisition, the Company will employ Michael
A. Jones, the founder and sole shareholder of Century, for a period of two years
from the closing date of the Century Acquisition. The Century Agreement includes
a noncompetition covenant prohibiting Mr. Jones from engaging in the temporary
staffing, consulting, staff leasing, payrolling, executive placement, permanent
placement or other related businesses for a period commencing at the closing
date of the Century Acquisition and continuing, subject to certain exceptions,
until the later of 36 months from the closing date or 24 months from the
termination of Mr. Jones' employment agreement.
 
COMPLETED ACQUISITIONS
 
     On September 22, 1997 and October 6, 1997, the Company completed its
acquisitions of TempWorks, Inc. ("TempWorks") and JesCo Technical Services, Inc.
("JesCo"), respectively. TempWorks provides commercial staffing services,
principally temporary clerical services, through a single office located in
Denver, Colorado. JesCo provides IT staffing and consulting services through two
offices located in Bellevue and Kirkland, Washington.
 
     In exchange for the assets of TempWorks, the Company paid an aggregate
purchase price of approximately $850,000. The purchase price paid by the Company
for the assets of JesCo consists of an initial payment of approximately $5.0
million and future contingent earnouts not to exceed $7.0 million. See
"Unaudited Pro Forma Condensed Financial Data" and "Business -- Recent and
Pending Acquisitions."
 
                                USE OF PROCEEDS
 
     The proceeds to the Company from the sale of the 3,000,000 shares of Common
Stock offered by the Company hereby are estimated to be $47.2 million, net of
estimated commissions and expenses. If the Underwriters' over-allotment option
is exercised in full, the proceeds to the Company from the sale of 3,600,000
shares, net of underwriting discounts, commissions and estimated expenses, are
estimated to be $56.8 million. The Company will not receive any proceeds from
the sale of shares of Common Stock by the Selling Shareholders.
 
     Approximately $13.0 million of the net proceeds will be used to repay
long-term debt estimated to be outstanding upon the completion of this offering,
which was incurred by the Company primarily to finance its growth strategy. The
Company's long-term debt bears interest at a rate equal to LIBOR plus 1.75%
(currently approximately 7.5%). Approximately $8.5 million of the net proceeds
will be used to repay borrowings expected to be outstanding on the Company's
line of credit on the closing date of this offering. The line of credit bears
interest at the lender's prime rate (currently 8.5% per annum) and has been used
to fund the Company's working capital needs and a portion of the cost of the
Company's recent acquisitions. In addition, the net proceeds will be used to pay
earnouts associated with the Company's recent acquisitions, which are estimated
to be approximately $5.0 million over the next twelve months.
 
     The Company intends to use a substantial portion of the balance of the net
proceeds for the acquisition of staffing and consulting businesses, including
the proposed Century Acquisition. See "Recent Developments -- Proposed Century
Acquisition." The Company continually reviews and evaluates acquisition
candidates to complement and expand its existing business, and is at various
stages of evaluation and discussion with a number of such candidates. To the
extent the proceeds of this offering are not utilized for acquisitions, they
will be added to working capital and used to support growth in the Company's
operations, including establishing additional offices.
 
     Pending use of the net proceeds of this offering for the above purposes,
the Company intends to invest such funds in investment grade, short-term,
interest bearing securities.

     The last sale price of the Common Stock, as reported on the Nasdaq National
Market, on October 15, 1997 was $16.875 per share. As of October 15, 1997, the
number of shares of Common Stock outstanding was 9,052,852 shares, held by
approximately 67 stockholders of record, which does not include shares held in
securities position listings.
 
                                DIVIDEND POLICY
 
     Other than a distribution of accounts receivable to its S corporation
shareholders prior to the Company's termination of its S corporation election
effective June 26, 1995, the Company has never declared or paid any dividends or
distributions on its capital stock and does not anticipate paying any such
dividends in the foreseeable future. In addition, the Company's current line of
credit prohibits the payment of dividends without the prior approval of the
lender. The Company currently intends to retain any future earnings to provide
funds for the further development and growth of its business, including
potential acquisitions of staffing businesses. The ability of the Company to pay
dividends in the future will be dependent upon earnings levels, liquidity,
capital needs, applicable covenants in the Company's loan agreements, general
business conditions and other factors considered relevant by the Company's Board
of Directors.

           UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL DATA
 
     The following unaudited pro forma condensed consolidated financial data is
based upon the historical financial statements of the Company included elsewhere
in this Prospectus or incorporated by reference herein, adjusted to give effect
to certain material acquisitions that were completed by the Company in 1996 and
1997 or are currently pending.
 
     The unaudited pro forma condensed consolidated balance sheet data as of
June 29, 1997 reflects the effect of the Company's acquisition of certain
staffing and consulting businesses which occurred subsequent to June 29, 1997 as
if they had occurred on such date.
 
     The unaudited pro forma condensed consolidated income statements for the
fiscal year ended December 29, 1996 and for the 26 weeks ended June 29, 1997
reflect the effect of certain acquisitions as if they had occurred at the
beginning of fiscal year 1996.
 
     The pro forma adjustments are based upon available information and certain
assumptions that management believes are reasonable. The unaudited pro forma
condensed consolidated statements of income are not necessarily indicative of
the future results of operations of the Company, its financial position or the
results of operations which may have occurred had these transactions occurred at
the beginning of fiscal year 1996.
 
     The unaudited pro forma condensed consolidated statements of income should
be read in conjunction with the consolidated financial statements of the Company
and related notes thereto, and Management's Discussion and Analysis of Financial
Condition and Results of Operations, included elsewhere in this Prospectus or
incorporated by reference herein.

                     NOTES TO UNAUDITED PRO FORMA CONDENSED
 
                       CONSOLIDATED FINANCIAL STATEMENTS
 
(1) BASIS OF PRESENTATION
 
     The unaudited pro forma condensed consolidated financial statements are
based on adjustments to the historical consolidated financial statements of the
Company to give effect to the acquisitions described in Note 2. The unaudited
pro forma condensed consolidated balance sheet assumes the acquisitions
described in Note 2 which were consummated after June 29, 1997 were consummated
on that date. The unaudited pro forma condensed consolidated statements of
income assume all the acquisitions described in Note 2 were consummated as of
the beginning of the periods presented. The unaudited pro forma condensed
consolidated statements of income are not necessarily indicative of results that
would have occurred had the acquisitions been consummated as of the beginning of
the periods presented or that might be attained in the future. The pro forma
financial statements should be read in conjunction with the historical
consolidated financial statements of the Company, the historical financial
statements of the significant acquired companies and "Management's Discussion
and Analysis of Financial Condition and Results of Operations" included
elsewhere or incorporated by reference in this Prospectus.
 
(2) ACQUISITIONS
 
     All acquisitions have been accounted for as purchases and, accordingly, the
results of operations of the acquired companies have been included in the
consolidated results of operations of SOS from the date of acquisition. The pro
forma information presented includes the effect of earnout payments which have
been paid or estimated to be earned. The Company records contingent earnout
payments as additional goodwill when earned or paid. In addition to the selected
1996 and 1997 acquisitions described below, the Company has consummated other
acquisitions which were not included in the unaudited pro forma condensed
consolidated financial statements based upon their relative size.
 
SELECTED 1996 ACQUISITIONS
 
     Performance Group -- In July 1996, the Company purchased certain assets and
substantially all of the business operations of The Performance Group
("Performance Group") for approximately $5.1 million which includes earnouts
paid in 1997 of approximately $1.5 million.
 
     Wolfe -- In November 1996, the Company purchased the stock of Wolfe &
Associates, Inc. ("Wolfe") for approximately $7.1 million which includes accrued
future contingent earnouts of approximately $3.0 million with total earnouts
(including the $3.0 million already accrued) not to exceed $6.0 million.
 
SELECTED 1997 ACQUISITIONS
 
     Computer Group -- In February 1997, the Company purchased the stock of
Computer Group, Inc. ("Computer Group") for approximately $2.7 million and
future contingent earnouts not to exceed $1.3 million.
 
     Bedford -- In July 1997, the Company purchased the stock of Bedford
Consultants, Inc. ("Bedford") for approximately $3.5 million and future
contingent earnouts.
 
     TPA -- In July 1997, the Company purchased certain assets and substantially
all of the business operations of Telecom Project Assistance, Inc. ("TPA") for
approximately $2.0 million and future contingent earnouts not to exceed $4.0
million.
 
     Execusoft -- In August 1997, the Company purchased certain assets and
substantially all of the business operations of Execusoft, Inc. ("Execusoft")
for approximately $5.0 million and future contingent earnouts not to exceed $3.5
million.

                 CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     JesCo -- In October 1997, the Company purchased certain assets and
substantially all of the business operations of JesCo for approximately $5.0
million and future contingent earnouts not to exceed $7.0 million.
 
(3) PRO FORMA ADJUSTMENTS
 
     The following pro forma adjustments have been made to the historical
condensed consolidated balance sheet of SOS to give effect to the acquisitons of
Bedford, TPA, Execusoft and JesCo described in Note 2 as if the acquisitions had
occurred as of June 29, 1997 and to the historical statements of income as if
all acquisitions described in Note 2 were consummated as of the beginning of the
periods presented:
 
          (a) To reflect the acquisitions and the related long-term borrowings
     under the Company's credit agreement or the reduction of cash used to fund
     the acquisitions.
 
          (b) To eliminate assets not acquired and liabilities not assumed by
     SOS in connection with the acquisitions.
 
          (c) To reduce expenses for the difference between compensation of
     certain key sellers prior to consummation of the acquisitions and their
     compensation following the acquisitions as stipulated in the respective
     employment agreements with SOS.
 
          (d) To reflect amortization of goodwill which is being amortized on a
     straight-line basis over 30 years.
 
          (e) To reflect amortization of other intangible assets (employee and
     customer lists, non-compete agreements and customer contracts) which are
     being amortized on a straight-line basis over 3 years.
 
          (f) To reflect the net (i) interest expense on the borrowings used to
     fund certain acquisitions, (ii) the elimination of historical interest
     expense related to debt not assumed by SOS, (iii) the elimination of
     historical interest expense related to acquisitions initially funded with
     debt and assumed to be funded with proceeds from the sale of common stock
     which closed in December 1996 (see (h) below), and (iv) the elimination of
     historical interest income for public offering proceeds utilized to fund
     certain acquisitions.
 
          (g) To reflect (i) the change in income taxes related to pro forma
     adjustments, and (ii) income taxes on the acquired companies that were S
     corporations prior to the acquisition.
 
          (h) To reflect the additional shares of common stock that would have
     been outstanding as a result of the Company's public offering which closed
     in December 1996, the proceeds from which were utilized to fund certain
     acquisitions.

(1) The Company completed its IPO in July 1995 and in connection therewith
    terminated its S corporation election. Data for fiscal 1995 has been
    adjusted to reflect a pro forma provision for income taxes. In addition,
    prior to the IPO, the Company compensated Richard D. Reinhold, its former
    CEO, at levels sufficient to pay income taxes associated with its S

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion should be read in conjunction with the financial
statements and notes thereto appearing elsewhere in this Prospectus or
incorporated by reference herein. The Company's fiscal year consists of a 52 or
53-week period ending on the Sunday closest to December 31.
 
GENERAL
 
     The Company provides a full range of staffing services through a network of
116 offices in 16 states. Since the completion of the IPO in July 1995, the
network has grown from 42 to 116 offices. The Company has expanded its office
network by acquiring existing staffing service companies and opening new
offices, principally in the western states. Historically, the Company has
entered key metropolitan areas by initially acquiring or opening a central or
"hub" office, and subsequently developing additional offices in the surrounding
metropolitan area or smaller surrounding markets. As offices reach certain
thresholds, the Company often divides them into one or more additional offices
resulting in greater efficiency, profitability and market penetration.
 
     Since the IPO, the Company has acquired 30 staffing companies, representing
42 offices, and has executed an agreement to acquire an additional company. The
purchase prices of the Company's completed acquisitions have ranged from $25,000
to $5,000,000, plus contingent earnouts. The Company has generally negotiated an
earnout component of the purchase price paid for acquisitions, which the Company
believes more accurately reflects the appropriate value for the acquired
business, provides a significant incentive for sellers who remain in a
management capacity with the acquired company, aligns the interests of the
Company and the sellers and enhances the likelihood of successfully integrating
the acquired company into SOS.
 
     Since the IPO, the Company also opened 32 new offices through internal
expansion. Capital costs of new office openings, excluding working capital
requirements, have typically ranged from $10,000 to $30,000. To date, most of
the Company's internally developed offices have achieved profitability within
six to 12 months, while offices resulting from the division of an existing
larger office are usually profitable from inception.
 
     Substantially all of the Company's service revenues are based on the time
worked by its staffing and consulting employees on customer assignments. Service
revenues are recognized as income at the time services are provided. The Company
defines gross profit as service revenues less the cost of providing services,
which includes wages of staffing and consulting employees, employer payroll
taxes (FICA, unemployment and other general payroll costs) and workers'
compensation costs. Operating expenses include compensation of staffing
employees, rent, recruitment of staffing employees, costs associated with
opening new offices, depreciation, amortization and advertising. Gross profit
and operating margins vary depending on the mix of the Company's business.

(1) Prior to 1995, the Company compensated its former CEO at levels sufficient
    to pay income taxes associated with S corporation status. Effective January
    1995, the Company entered into an employment contract with the CEO which
    provided for annual compensation of $195,000 in 1995. Fiscal 1994 selling,
    general and administrative expenses have been adjusted to reflect CEO
    compensation in such amount, resulting in a reduction of $787,000.
 
TWENTY-SIX WEEKS ENDED JUNE 29, 1997 COMPARED TO TWENTY-SIX WEEKS ENDED JUNE 30,
1996
 
     Service Revenues. Service revenues for the 26 weeks ended June 29, 1997
were $87.4 million, an increase of $32.4 million, or 59%, from $55.0 million for
the same period of 1996. Approximately $16.7 million of the increase was
attributable to offices acquired in 1996 and 1997. Service revenues (excluding
acquisitions) grew by $15.7 million during the period, consisting of
approximately $11.2 million attributable to growth from comparable offices and
approximately $4.5 million attributable to opening new offices.
 
     Gross Profit. Gross profit for the 26 weeks ended June 29, 1997 was $18.9
million, an increase of $7.6 million, or 67%, from $11.3 million for the same
period of 1996. Gross profit margin for the 26 weeks ended June 29, 1997 was
21.7%, compared to 20.6% for the same period of 1996, reflecting, in part, a
shift in business mix towards the IT segment, which typically generates higher
gross margins.
 
     Operating Expenses. Operating expenses for the 26 weeks ended June 29, 1997
amounted to $14.2 million, or 16.2% of service revenues, compared to $8.7
million, or 15.8% of service revenues, for the same period of 1996. The increase
in operating expenses as a percentage of service revenues was attributable to an
increase in amortization of intangible assets.
 
     Operating Income. Operating income for the 26 weeks ended June 29, 1997 was
$4.8 million, an increase of $2.2 million, or 81%, from $2.6 million for the
same period of 1996. Operating margin for the 26 weeks ended June 29, 1997 was
5.5%, compared to 4.8% for the same period of 1996.
 
     Income Taxes. The effective combined federal and state income tax rate for
the twenty-six weeks ended June 29, 1997 and June 30, 1996 was 40.4% and 38.0%,
respectively. The increased combined tax rate was due to an increase in
non-deductible amortization of intangible assets relating to certain
acquisitions and increasing operations in states which assess higher state tax
rates.

FISCAL 1996 COMPARED TO FISCAL 1995
 
     Service Revenues. Service revenues for fiscal 1996 were $136.2 million, an
increase of $48.7 million, or 56%, from $87.5 million in fiscal 1995. Of the
$48.7 million increase, $24.1 million was attributable to acquisitions, $20.1
million was attributable to comparable offices and $4.5 million was attributable
to new offices.
 
     Gross Profit. Gross profit for fiscal 1996 was $27.6 million, an increase
of $9.4 million or 52%, compared to $18.2 million in 1995. Gross profit margin
for fiscal 1996 was 20.3%, compared to 20.7% in fiscal 1995, reflecting, in
part, upward pressure on wages due to lower unemployment rates in the Company's
service areas.
 
     Operating Expenses. Operating expenses amounted to $20.9 million, or 15.4%
of service revenues, in fiscal 1996 compared to $13.9 million, or 15.8% of
service revenues, in fiscal 1995. The decrease in operating expenses as a
percentage of service revenues resulted from improved operating leverage
attributable to revenue growth partially offset by an increase in amortization
of intangible assets.
 
     Operating Income. Operating income for fiscal 1996 was $6.7 million, an
increase of $2.4 million, or 55%, from $4.3 million in fiscal 1995. Operating
margin for both fiscal 1996 and fiscal 1995 was 4.9%.
 
     Income Taxes. The effective combined federal and state income tax rate for
fiscal 1996 and fiscal 1995 was 38.1% and 39.2%, respectively.
 
FISCAL 1995 COMPARED TO FISCAL 1994
 
     Service Revenues. Service revenues for fiscal 1995 were $87.5 million, an
increase of $23.8 million, or 37%, from $63.7 million in 1994. Approximately
$14.2 million of the increase was attributable to acquisitions, approximately
$6.6 million was attributable to comparable office sales and approximately $3.0
million was attributable to opening new offices. The increase in service
revenues attributable to comparable offices was consistent with increases in
hours billed, coupled with a better mix of business.
 
     Gross Profit. Gross profit for fiscal 1995 was $18.2 million, an increase
of $5.8 million, or 46%, from $12.4 million in fiscal 1994. Gross profit margin
for fiscal 1995 was 20.7% compared to 19.5% in fiscal 1994. The improvement in
gross profit margin was due primarily to the Company's focus on a higher margin
mix of business. Gross margins were also positively affected by continued
emphasis on the use of flexible pricing strategies and workers' compensation
loss control.
 
     Operating Expenses. Operating expenses for fiscal 1995 amounted to $13.9
million, or 15.8% of service revenues, compared to $9.3 million (adjusted for
CEO compensation), or 14.5% of service revenues, for fiscal 1994. The increase
as a percentage of service revenues was attributable largely to the addition of
personnel at the Company's headquarters and regional office levels to support
the Company's growth, including planned future growth. Other increases were
attributable to opening new offices, integrating newly-acquired offices and
becoming a public company.
 
     Operating Income. Operating income for fiscal 1995 was $4.3 million, an
increase of $1.1 million, or 37%, from $3.2 million (adjusted for CEO
compensation) in fiscal 1994. Operating margin was 4.9% in fiscal 1995 and 5.0%
in fiscal 1994.

PRO FORMA RESULTS OF OPERATIONS
 
     The following pro forma financial information is presented to provide a
comparison of pro forma operating results to actual operating results due to
certain of the Company's material acquisitions completed or entered into after
the beginning of the periods presented. See "Unaudited Pro Forma Condensed
Consolidated Financial Data."
 
PRO FORMA RESULTS OF OPERATIONS COMPARED TO ACTUAL RESULTS FOR THE 26 WEEKS
ENDED JUNE 29, 1997
 
     Service Revenues. Pro forma service revenues from acquisitions added $14.8
million to actual service revenues. If these acquisitions had occurred at the
beginning of 1997, service revenues would have amounted to $102.2 million.
 
     Gross Profit. Pro forma gross profit was $23.3 million, an increase of $4.4
million over the actual results reported of $18.9 million. Pro forma gross
profit margin was 22.8%, compared to 21.7% from actual results for the same
period. The increase in gross profit margin was attributable to a higher mix of
IT business in the pro forma results which typically generate a higher margin.
 
     Operating Expenses. Pro forma operating expenses were $17.2 million, an
increase of $3.0 million over actual results. As a percentage of service
revenues, pro forma operating expenses were 16.8% or an increase of 0.6%,
compared to the actual percentage of 16.2%. Part of the increase resulted from
an increase in the mix of IT business, which typically generates higher
operating expenses. The balance of the increase resulted from additional
amortization of intangible assets related to the acquisitions.
 
     Operating Income. Pro forma operating income was $6.1 million, an increase
of $1.4 million. Pro forma operating income as a percentage of service revenues
was 6.0%, compared to the actual percentage of 5.5%.
 
     Income Taxes. The pro forma provision for income taxes represented an
effective rate of 40.6%, compared to 40.4% for actual results.
 
PRO FORMA RESULTS OF OPERATIONS COMPARED TO ACTUAL RESULTS FOR FISCAL 1996
 
     Service Revenues. Pro forma service revenues from acquisitions added $34.4
million to actual service revenues. If these acquisitions had occurred at the
beginning of 1996, service revenues for fiscal 1996 would have amounted to
$170.6 million.
 
     Gross Profit. Pro forma gross profit was $37.4 million, an increase of $9.9
million over the actual results reported. Gross profit margin was 21.9%,
compared to the actual percentage of 20.3%. The increase in gross profit margin
was attributable principally to the increase in the IT business.
 
     Operating Expenses. Pro forma operating expenses were $29.5 million,
reflecting the addition of $8.6 million in operating expenses, compared to the
actual results. As a percentage of service revenues, pro forma operating
expenses were 17.3%, or an increase of 1.9%, compared to the actual percentage
operating expenses of 15.4%. Part of the increase resulted from an increase in
the mix of IT business. The balance of the increase resulted from additional
amortization of intangible assets related to the acquisitions.
 
     Operating Income. Pro forma operating income was $7.9 million, an increase
of $1.2 million over the actual operating results of $6.7 million. Pro forma
operating income as a percentage of service revenues was 4.6% compared to the
actual percentage of 4.9%.
 
     Income Taxes. The pro forma provision for income taxes represented an
effective rate of 40.9%, compared to 38.1% for actual results. The increase in
the effective tax rate was due to the acquisition of businesses in states with
higher income tax rates, as well as an increase in non-deductible amortization
of intangible assets relating to certain acquisitions.

     Results of operations for the quarters shown above include the results of
operations of services businesses acquired during such periods. The quarterly
results set forth above may not be indicative of the future operating results of
the Company. The Company's quarterly results are also affected by seasonal
trends in the Company's business. See "Risk Factors -- Quarterly Variations in
Results" and "-- Seasonality."
 
LIQUIDITY AND CAPITAL RESOURCES
 
     For the 26 weeks ended June 29, 1997, net cash provided by operating
activities was $0.6 million compared to net cash used in operating activities of
$1.5 million for the 26 weeks ended June 30, 1996. The increase in operating
cash flow was a result of higher net income and increased depreciation and
amortization.
 
     The Company's investing activities used $0.7 million to purchase property
and equipment, $3.8 million to purchase assets of acquired businesses and $0.4
million to pay earnouts on acquisitions. See "Business -- Recent and Pending
Acquisitions" and the Notes to the Company's Consolidated Financial Statements
incorporated by reference herein for a description of the material terms of
these acquisitions.
 
     The Company's primary sources of short-term liquidity and capital resources
at June 29, 1997 were cash flows from operating activities and a secured line of
credit with a bank. The Company's line of credit allowed for maximum borrowings
of $20 million at June 29, 1997 and was increased to $35 million in September
1997. At June 29, 1997, the Company had outstanding borrowings of $0.5 million
on the line of credit, consisting solely of short-term borrowings. Short-term
borrowings bear interest at the prime rate charged from time to
 
                                       26
<PAGE>   27
 
time by the Company's lender (at June 29, 1997, 8.5%). Long-term borrowings bear
interest at LIBOR plus 1.75% (at June 29, 1997, approximately 7.5%). The rate
related to the amount over LIBOR may increase based upon certain financial
ratios. The Company also had letters of credit of $3.7 million outstanding at
June 29, 1997, for purposes of securing its workers' compensation premium
obligation. The aggregate amount of such letters of credit reduces the borrowing
availability on the line of credit. At June 29, 1997, $15.8 million was
available for borrowings or additional letters of credit under the line of
credit. Management believes that the new credit facility, together with cash
reserves and cash flow from operations, will be sufficient to fund the Company's
operations, capital expenditures, and pending acquisitions for at least the next
12 months. The Company will utilize proceeds of this offering to repay debt, to
pay earnout obligations associated with prior acquisitions, to support continued
growth of operations, including opening additional offices, and for working
capital and general corporate purposes.
 
SEASONALITY
 
     The Company's business follows the seasonal trends of its customers'
businesses. Historically, the Company has experienced lower revenues in the
first quarter due to the seasonal trends of its customers and lower overall
economic activity.
 
IMPACT OF INFLATION
 
     The Company believes that over the past three years inflation has not had a
significant impact on the Company's results of operations.

                                    BUSINESS
 
GENERAL
 
     The Company is a leading provider of staffing services in the western
states. SOS currently operates a network of 116 offices in 16 states. The
Company provides a broad range of commercial staffing and IT services.
Commercial staffing services include light industrial, clerical, industrial,
technical, specialty and other professional services. IT services consist of
staffing, consulting and outsourcing services such as systems design,
programming, network and systems management and business consulting. During the
26 weeks ended June 29, 1997, the Company provided approximately 41,000 staffing
employees to more than 6,400 businesses, professional and service organizations
and government agencies.
 
     Since completing its IPO in July 1995, the Company has aggressively pursued
an acquisition program, having acquired 30 staffing companies with 42 offices,
consisting of 28 commercial staffing offices and 14 IT staffing and consulting
offices. Nine of the acquisitions completed since July 1996 were of IT staffing
and consulting companies, which have allowed the Company to diversify the mix of
staffing services provided to include higher margin services. On a pro forma
basis, revenues from IT staffing services represented 24% of total revenues for
the 1996 fiscal year and 25% of total revenues for the 26 weeks ended June 29,
1997. Additional acquisitions have added other specialty services, including
medical administrative support, professional mining, geology, hydrology and
environmental services.
 
STAFFING INDUSTRY
 
     The staffing industry in the United States has grown rapidly and has been
among the country's fastest growing industries during the last five years,
according to the U.S. Bureau of Labor Statistics. According to NATSS, domestic
staffing receipts for 1996 were approximately $43.6 billion, an increase of
approximately 11.2% from 1995. NATSS has also reported that temporary employees
represented approximately 1.9% of the non-farm workforce during 1996, up from
0.9% in 1989.
 
     The professional and technical segments of the industry, which include IT
professionals, have experienced higher rates of growth than the office/clerical
segment. According to NATSS, from 1991 to 1996, the percentage of temporary
staffing payroll represented by the professional and technical segments
increased from 15.8% to 20.3%, compared with a decrease in the office/clerical
segment from 47.6% to 38.7% during the same period.
 
     Historically, the demand for staffing employees has been driven primarily
by a need to temporarily replace regular employees due to illness, vacation or
termination. More recently, competitive pressures have forced businesses to
focus on reducing costs, including converting fixed labor costs to variable and
flexible costs. Increasingly, the use of staffing employees has become widely
accepted as a valuable tool for managing personnel costs and for meeting
specialized or fluctuating employment requirements.
 
     The range of staffing services has expanded substantially since the early
days of the staffing industry. Technological advances, as well as changing
attitudes towards workforce management, have resulted in a proliferation of new
staffing positions in such areas as IT and other specialized industry segments.
Furthermore, businesses have begun using staffing employees to reduce
administrative overhead by outsourcing operations that are not part of the
organizations' core business functions. Outsourcing involves a provider assuming
responsibility for managing a specific facility or function, such as help desk,
data processing, mailroom or maintenance operations. Staffing companies also
offer on-site services, which involve locating one of the staffing company's
regular employees on-site at the customer's place of business to manage all of
the customer's employee staffing requirements. As business information systems
have become more complex and sophisticated, businesses have increasingly sought
assistance from IT staffing and consulting personnel to develop and support
their operations.

REGIONAL GROWTH
 
     The Company has benefited significantly from strong economic and population
growth in the Mountain States and improving economic conditions in certain
western states. Management believes the attraction of the Mountain States,
resulting in part from the region's economic growth, diverse economic base,
productive work force and high quality of life, will result in further economic
expansion. Of the ten states forecast by Regional Financial Review to experience
the highest rates of growth in gross output of goods and services during 1997,
five are located in the Mountain States and the Company has offices in four
others. Job growth in the Company's markets is projected to be strong. According
to the Regional Financial Review, in 1998, non-farm employment in the Mountain
States is projected to increase by 3.0%, compared to the national average of
1.2%.
 
     Management believes the economic strength and projected job growth in the
western states will support the Company's anticipated growth and enable the
Company to pursue additional growth opportunities.
 
RECENT AND PENDING ACQUISITIONS
 
     Since January 1997, the Company has acquired 11 staffing businesses,
representing eight IT staffing and consulting offices and six commercial
staffing offices, and has announced an agreement to acquire an additional
company which, if completed, would add 13 additional commercial staffing
offices. The Company's recent and pending acquisitions are summarized in the
following table. See "Recent Developments" and "Unaudited Pro Forma Condensed
Consolidated Financial Data" for additional information concerning certain of
these acquisitions.

GROWTH STRATEGY
 
     Management believes the Company has substantial opportunities to expand its
office network and the range of services it offers to its customers. The
Company's growth strategy is comprised of two elements: continued focus on
internal growth and pursuit of additional acquisitions. Since completing its IPO
in July 1995, the Company has added a total of 32 offices through internal
growth and 42 offices through acquisitions.
 
     Focus on Internal Growth. A principal element of the Company's growth
strategy has been its focus on internal growth. During the last five years, the
Company has maintained an average annual internal revenue growth rate in excess
of 20%. The Company's internal growth strategy consists of the following:
 
     - Increase Penetration of Existing Markets. The Company continually seeks
       to add new customers and offices in the geographic markets it currently
       serves. In many instances, the Company pursues such penetration by
       establishing a "hub" office from which it can develop additional offices
       within a metropolitan area. SOS also intends to introduce complementary
       or specialty services in existing markets and incentivizes field and
       local managers to focus on business development within existing offices.
 
     - Enter New Markets. The Company plans to open new branches in markets not
       currently served by existing offices. Frequently, the Company enters new
       markets by establishing a "hub" office located in a central location. The
       Company then opens new offices in surrounding markets which benefit from
       the administrative support and resources of the hub office. This strategy
       has enabled the Company to enter many smaller markets cost effectively.
 
     - Expand Service Offerings. The Company is actively seeking to expand the
       range of IT services it offers to its customers to include expanded
       outsourcing capabilities and network oversight and management. The
       Company intends to expand its vendor on-premise business, pursuant to
       which SOS manages all of the customer's staffing requirements on-site.
       The Company also intends to further develop partnering relationships
       under which SOS works with other staffing providers to meet the
       customer's staffing requirements.
 
     - Cross-sell Services. The Company actively seeks to cross-sell commercial
       staffing and IT staffing and consulting services to existing customers.
       Through incentive compensation arrangements, the Company actively
       encourages referrals and cross-selling among and within its commercial,
       specialty and IT operations.
 
     Pursue Acquisitions. The Company intends to continue to pursue acquisitions
as a key element of its growth strategy. In targeting acquisitions, SOS focuses
on businesses with (i) a history of profitable operations, (ii) a strong
management team, (iii) a strong local market position, (iv) services that
complement the Company's operations and (v) compatible corporate philosophies
and culture. The estimated total annualized revenues of the 12 staffing
businesses acquired by the Company since January 1997 (including the pending
Century Acquisition) are approximately $60.8 million. See "-- Recent and Pending
Acquisitions." The Company's acquisition growth strategy consists of the
following:
 
     - Enter New Markets. The Company intends to target strategic acquisitions
      in new markets where the Company seeks to establish staffing operations,
      particularly in the western states.
 
     - Acquire Complementary Businesses in Existing Markets. The Company intends
      to acquire complementary businesses or specialty lines of business that
      enhance the services provided by existing offices. The Company also
      targets businesses in its existing markets as a means of increasing market
      share.
 
     - Acquire New Services. The Company intends to pursue acquisitions of
      staffing businesses that will expand its service offerings. The Company's
      acquisition of nine IT companies since July 1996 has significantly
      strengthened the Company's IT staffing and consulting offerings. As the
      Company identifies staffing businesses in attractive niches, the Company
      intends to pursue strategic acquisitions to facilitate its entry into such
      niches.

BUSINESS STRATEGY
 
     The Company's goal is to enhance its profitability through a focused
business strategy. The Company has identified the following key elements of its
strategy, which management believes are critical to the Company's success:
 
     Focus on Small to Mid-Size Customers. Historically, the Company's customers
have consisted primarily of small to mid-size companies. Sales to these
businesses tend to generate higher margins than larger national accounts. The
Company believes that focusing on small to mid-sized customers limits its
exposure to margin pressure associated with large national contracts and volume
discounts. The Company believes that it has developed competitive advantages in
serving small and mid-sized businesses by tailoring its operations to meet local
customer needs, including the establishment of strong customer relationships
through local marketing efforts, quality service and community involvement.
 
     Deliver Higher Margin Services. The Company's operating results since 1991
have been significantly enhanced by its strategy to deliver higher margin
services. Over the past several years, the Company has focused its efforts on
expanding its range of services to include higher margin specialty services such
as IT staffing and consulting, administrative staffing support services for
medical facilities and other professional services. The Company has
de-emphasized marketing to accounts where competitive pricing makes margins
unacceptable or to accounts where workers' compensation costs adversely affect
profitability.
 
     Offer a Broad Range of Services. The Company's strategy includes offering
its customers a broad range of staffing services, including light industrial,
clerical, IT, industrial, technical and other professional services, as well as
a range of consulting services. The Company also provides related services to
its customers, including payrolling, skill and drug testing, risk management
consulting and other professional staffing services. In larger markets, the
Company offers these services through several separate offices operating under
established names. The Company also provides outsourcing services to customers
whereby the Company contracts to perform a particular business function for an
agreed price, which includes providing staffing, equipment and supplies. The
Company is also expanding its on-site services, in which SOS locates an on-site
manager at the customer's facility to manage all of the customer's employee
staffing requirements.
 
     Provide Centralized Support and Encourage Entrepreneurial Management. The
Company's commercial staffing offices are supported by centralized functions at
corporate headquarters that include marketing, recruiting, training and
retention programs, as well as workers' compensation and other insurance
services, accounts payable, purchasing, credit, collection, legal review and
other administrative support services. Generally, each staffing office has
access to the Company's computer system and its proprietary software that
provides information on customer requirements, available applicants, staffing
employees on assignment and other information which facilitates efficient
response to customer job orders. As the Company expands its IT staffing,
consulting and outsourcing operations, it intends to develop a centralized
support system tailored to the specific needs of IT customers.
 
     To encourage an entrepreneurial approach to field management, the Company
has established financial targets and quality performance standards which are
utilized at all offices. A substantial portion of the Company's field management
compensation is incentive-driven and based upon meeting financial targets and
quality standards. Managers are also given considerable discretion to price
services and to respond to specific customer requirements.
 
     Emphasize Service and Value. The Company focuses on providing service and
value to its customers. The Company's staff employees seek to establish and
maintain long-term relationships with its customers by developing knowledge of
customers' businesses, responding promptly to customer orders and monitoring job
performance and customer satisfaction. The Company targets customer accounts
where service and quality are perceived to be as important as pricing of
services. This allows the Company to be more selective and to provide higher
quality services while maintaining desired margins.
 
     Pursue Opportunities in Smaller Markets. In the commercial staffing
segment, SOS has focused on opening hub offices in key metropolitan areas
followed by establishing offices in surrounding markets. This decentralized
office management strategy locates multiple offices in close proximity to
customers and staffing
 
                                       31
<PAGE>   32
 
employees. The Company believes this strategy has allowed it to rapidly gain
market share with low entry costs. Once a hub office has been established, the
Company focuses on leveraging hub office resources to market and deliver
services to surrounding smaller markets and to cross-sell IT and other specialty
staffing services. In these markets, which are often too small to attract
substantial competition from national staffing companies, the Company has
quickly achieved significant penetration and has often become the dominant
provider of staffing services.
 
OPERATIONS
 
     Services Offered. The Company offers a broad range of commercial staffing
and IT staffing and consulting services. Generally, the Company provides light
industrial, clerical and industrial services through SOS Staffing Services,
Skill Staff and Industrial Specialists offices, while technical and other
specialty services are provided by specialty offices such as SOS Technical
Services (engineers, chemists, geologists, designers, drafters, illustrators,
artists, writers and other technical personnel), AccountStaff (accountants,
bookkeeping, auditors, data entry personnel and financial analysts), PAMS
(medical administrative services), National Collex (collection services and
project billing for medical facilities) and CGS Personnel (mining, mineral
exploration and environmental staffing).
 
     The Company's commercial staffing services also include professional
employer services such as payrolling, outsourcing, on-site and administrative
professional services provided through SOS Staffing Services and ServCom
offices. Payrolling typically involves the transfer of a customer's short-term
seasonal or special use employees to the Company's payroll for a designated
period. Outsourcing represents a growing trend among businesses to contract with
third parties to provide a particular function or business department for an
agreed price over a designated period. On-site services involve locating a
regular SOS employee at the customer's place of business to manage all of the
customer's temporary staffing requirements. Administrative professional services
offer SOS customers skills testing, drug testing and risk management services.
Skills testing available to SOS customers includes cognitive, personality and
psychological evaluations. Drug tests are confirmed through an independent
certified laboratory. Risk management services include on-site safety inspection
and consulting services. As of September 1, 1997, the Company also provided
professional employer organization services on a limited basis to approximately
60 customers, representing approximately 340 employees, which offers to SOS
customers the benefits of employee leasing.
 
     The Company's IT services consist of IT staffing, consulting and
outsourcing services. The Company's IT staffing services include computer
programming, system design, analysis and administration, network and systems
management, software and documentation development. IT staffing services are
similar in many respects to commercial staffing services; however, IT services
generally, require increased specialization and technical skill, carry
significantly higher hourly rates and involve substantially longer job
assignments. The Company's IT consulting services are focused on solving the
customer's organizational problems and typically include general business
consulting, organizational analysis, technology consulting, strategic planning
and telephony services. Company consultants provide innovative ideas, insight
and experience to address the customer's organizational problems, then work with
the customer to implement strategic solutions. IT consulting engagements
typically last six months to one year and may require the services of several
specialized consultants. The Company also delivers IT outsourcing services to
customers who turn over to SOS personnel the management and staffing of specific
business operations. Historically, the Company has provided IT staffing,
consulting and outsourcing services under the business names of acquired IT
business units; however, as the Company integrates acquired IT companies into
its consolidated IT operations, the Company intends to adopt common business
names for use throughout the Company's IT branch network.
 
     Branch Offices. The Company provides commercial staffing and IT staffing
and consulting services through a network of 116 offices located in 16 states.
The Company currently operates at least one office in every market in the
Mountain States with a population base in excess of 100,000 people. In larger
markets, the Company generally provides light industrial and clerical personnel
through SOS Staffing Services offices, while specialty services are provided by
service-specific specialty offices. In smaller markets, SOS offices offer a
broader variety of commercial staffing services, including specialty services.
The Company currently provides
 
                                       32
<PAGE>   33
 
commercial staffing services through a network of SOS Staffing Services, Skill
Staff, SOS Technical Services, AccountStaff, Industrial Specialists, PAMS,
ServCom and CGS offices.
 
     The Company estimates the capital cost of establishing a new commercial
staffing office ranges from $10,000 to $30,000, exclusive of working capital
requirements. The Company's new offices have historically achieved profitability
in six to 12 months, while offices created by division of an existing office are
usually profitable from inception.
 
     The Company provides IT staffing and consulting services from 16 IT
offices. The Company's IT staffing and consulting offices generally serve larger
geographic areas than SOS commercial staffing offices, principally due to the
increased specialization associated with IT services. The Company's strategy of
integrating and expanding its existing IT staffing and consulting office network
will include efforts to position IT offices in strategic locations throughout
the western states, rather than the "hub and spoke" approach used by the Company
to expand its network of commercial staffing offices.
 
     Sales and Marketing. SOS generally markets its commercial staffing services
through its network of offices whose managers, supported by the Company's
marketing staff, make regular personal sales visits to larger accounts and
prospects. The Company emphasizes long-term personal relationships with its
customers and develops these relationships through regular contact, periodic
assessment of customer requirements and regular monitoring of employee
performance. New customers are obtained through customer referrals,
telemarketing and advertising in a variety of local and regional media,
including television, radio, direct mail, Yellow Pages, newspapers, magazines
and trade publications. The Company is also a sponsor of job fairs and other
community events.
 
     The Company's IT sales and marketing efforts may include the activities
described above, but are generally more focused to address IT staffing and
consulting needs which are typical of specific customers. Many of the Company's
existing and prospective IT customers routinely outsource IT functions, such as
programming, data entry and network administration. The Company's IT staffing
and consulting personnel seek to identify IT requirements of its customers and
promote IT services designed to meet those requirements. In addition to personal
sales visits, targeted mailings and telephone solicitations, the Company's IT
personnel actively promote the Company's services through cross-selling
complementary IT services to existing customers and participate in industry
trade associations.
 
     Recruiting. The Company believes a key element of its growth and
profitability has been its ability to recruit and retain qualified staffing
personnel. In an effort to attract commercial staffing personnel, the Company
employs recruiters who regularly visit schools and professional associations and
present career development programs to various organizations. In addition, the
Company obtains applicants from referrals by its staffing employees and from
advertising on radio, television, in the Yellow Pages and through other print
media. The Company has recently begun to utilize the internet to recruit
professional, IT and technical staffing employees. Each applicant for a
commercial staffing position is interviewed with emphasis on past work
experience, personal characteristics and individual skills. The Company utilizes
the Dictionary of Occupational Titles ("DOT Codes") published by the Department
of Labor to evaluate and assign staffing employees. The Company maintains
software training programs at its offices for applicants and employees who may
be trained and tested at no cost to the applicant, employee or Company customer.
 
     The Company's efforts to recruit IT staffing and consulting personnel
frequently include some or all of the recruiting activities employed by the
Company's commercial staffing offices, but typically rely more heavily on
identifying potential employees who possess specialized education, training or
work experience. Frequently, the Company will screen prospective IT personnel
based solely upon resume submissions, then refer qualified candidates to
customers for on-site interviews. The Company's IT recruiting efforts also rely
heavily upon industry contacts, personal networks and referrals from existing
and former IT personnel.
 
     To promote loyalty and retention among its staffing employees, the Company
provides its staffing employees with certain employee benefits, including access
to a Section 401(k) defined contribution plan, a credit union and health
insurance programs offered through NATSS. In addition, the Company generally
issues paychecks to commercial staffing employees during the same week worked.
 
                                       33

     Customers. During the 26 weeks ended June 29, 1997, the Company provided
approximately 41,000 staffing employees to more than 6,400 businesses,
professional and service organizations and government agencies. No customer
accounted for more than 3% of the Company's service revenues during the period
and the Company's top ten customers accounted for less than 15% of service
revenues during the same period. Historically, the Company's customers have
consisted primarily of small to mid-size commercial staffing customers.
Management believes there remain significant opportunities to deliver profitable
commercial staffing services to small and mid-size customers, who are less
likely to require substantial volume discounts than larger, nationwide
companies. As the Company expands its network into larger cities in the western
states, the Company anticipates that it will provide commercial staffing
services to larger customers who focus on value rather than cost, but will
continue to focus its efforts on attracting and providing quality services to
small and mid-size companies located in such larger cities.
 
     The Company's IT customer base, which consists primarily of IT customers
served by companies acquired by SOS since July 1996, includes customers who are
generally larger than many of the Company's commercial staffing customers. Many
of the Company's IT customers are Fortune 1000 companies, government agencies
and educational institutions. The Company anticipates that its increased focus
on IT staffing and consulting, as well as its expansion into larger metropolitan
areas, will lead to additional opportunities to provide IT services to mid-size
and larger customers.
 
     Information Systems. The Company's central management information system is
linked to all of the Company's larger staffing offices. Smaller offices utilize
stand-alone computers and software for routine office functions. The centralized
system is designed to support Company-wide operations such as payroll, billing,
accounting and sales and management reports.
 
     Six of the 16 IT offices are linked to the Company's central management
information system, while substantially all of the remaining offices continue to
utilize systems in place at the time of their acquisition by SOS. The Company
intends to develop a central management information system for use by the
Company's IT offices. The Company anticipates that its IT system will be
connected to the Company's existing system for certain common functions;
however, the IT system will be designed to accommodate the different business
cycles associated with the IT industry.
 
     The operating system software utilized by the Company is licensed on a
perpetual royalty-free basis. The Company's proprietary application software is
regularly updated and revised to meet the Company's specific requirements. All
files are backed up routinely and stored off-site and critical files are backed
up on a daily basis. The present system has capacity to service the Company's
anticipated growth without significant capital expenditures for the foreseeable
future.
 
     Risk Management Program. SOS is responsible for all employee-related
expenses for its staff employees including workers' compensation, unemployment
insurance, social security taxes, state and local taxes and other general
payroll expenses. The Company has implemented a deductible workers' compensation
program through CIGNA Property and Casualty ("CIGNA") with a loss cap of
$200,000 per incident. Staffing employees in Nevada, Washington and Wyoming are
insured through those states' insurance funds because private insurance is not
permitted in those states. The Company employs a full-time professional risk
manager and staff who work closely with the insurance carrier to manage claims
and establish appropriate reserves.
 
     The Company has also developed workers' compensation loss control programs
which seek to limit claims through employee training and avoidance of high risk
job assignments such as roofing or logging. All staffing employees are required
to agree in advance to drug testing following any work-related accident and all
major accidents are investigated. The Company, in cooperation with its insurer,
monitors all claims and regularly reviews the claims with an emphasis on early
closure.
 
COMPETITION
 
     The staffing industry is comprised of national, regional and local
companies operating offices throughout the nation, making the industry highly
competitive and highly fragmented, with limited barriers to entry. The Company
faces intense competition from large national and international companies with
substantially greater
 
                                       34
<PAGE>   35
 
financial and marketing resources than those of the Company, as well as strong
local and regional staffing companies.
 
     The Company competes for qualified staffing employees and for customers who
require the services of such employees. The principal competitive factors in
attracting and retaining qualified staffing employees are competitive salaries
and benefits, quality and frequency of assignments and responsiveness to
employee needs. The Company believes that many persons who seek temporary
employment are also seeking regular employment and that the availability of
assignments which may lead to regular employment is an important factor in its
ability to attract qualified staffing employees.
 
     The principal competitive factors in obtaining customers are a strong sales
and marketing program, having qualified staffing employees to assign in a timely
manner, matching of customer requirements with available staffing employees,
competitive pricing and satisfactory work production. The Company believes its
strong emphasis on providing service and value to its customers and staffing
employees are important competitive advantages.
 
PROPERTIES
 
     Presently, the Company provides staffing services through 116 offices in 16
states. These offices typically consist of 1,200 to 1,500 square feet and are
leased by the Company for terms of three to five years. Offices in larger or
smaller markets may vary in size from the typical office. The Company does not
expect that maintaining or finding suitable lease space at reasonable rates in
its markets or in areas where the Company contemplates expansion will be
difficult.
 
     The Company's executive and administrative offices are located in Salt Lake
City, Utah. The premises consist of approximately 15,600 square feet and are
leased from a related party for a term ending on March 31, 2005 with an option
to renew for 10 additional years. The Company believes that the lease terms are
at least as favorable as could be obtained from any unrelated third party.
 
LEGAL AND ADMINISTRATIVE PROCEEDINGS
 
     In the ordinary course of its business, the Company is periodically
threatened with or named as a defendant in various lawsuits. The Company
maintains insurance in such amounts and with such coverage and deductibles as
management believes to be reasonable and prudent. The principal risks covered by
insurance include worker's compensation, personal injury, bodily injury,
property damage, errors and omissions, fidelity losses and general liability.
 
     In June 1997, a former customer of the Company commenced litigation against
the Company in Second District Court, Salt Lake County, State of Utah, alleging
breach of contract, negligence, fraud and misrepresentation. The allegations are
based upon the alleged theft of surplus military goods from the former
customer's warehouse by a former temporary employee of the Company. The
plaintiff is seeking special, general, consequential, punitive and other damages
in an amount in excess of $7.0 million. The Company believes the claim is
without merit and that the Company has valid defenses to all of the allegations
raised by the plaintiff.
 
     There is no other pending litigation that the Company currently anticipates
will have a material adverse effect on the Company's financial condition or
results of operations.
 
STAFF EMPLOYEES
 
     At August 25, 1997, the Company had approximately 627 staff employees
including 11 senior managers, 124 field managers, 68 consultants and 424 other
staff employees. The Company's training department provides general and job
specific training to all staff employees, including continuing training with
experienced counterparts. None of the Company's staff employees is covered by
collective bargaining agreements. The Company considers its relationship with
its staff employees to be good.

NEW MANAGEMENT APPOINTMENTS
 
     In August 1997, the Company announced certain new management appointments,
including the appointment of Howard W. Scott as Chief Executive Officer, JoAnn
W. Wagner as Vice Chairman of the Board and Executive Vice President of
Corporate Development and Peter R. Sollenne as President and Chief Operating
Officer. The appointments reflect the decision of Richard D. Reinhold, founder
and former Chief Executive Officer of the Company, to substantially decrease his
day-to-day involvement in the Company's operations. Mr. Reinhold will continue
to serve as Chairman of the Company's Board of Directors but is considering the
possibility of stepping down as Chairman some time in 1998.

     The Underwriting Agreement provides that the obligations of the
Underwriters to purchase shares of Common Stock are subject to certain
conditions, and that if any of the foregoing shares of Common Stock are
purchased by the Underwriters pursuant to the Underwriting Agreement, all the
shares of Common Stock agreed to be purchased by the Underwriters must be so
purchased.
 
     The Company and the Selling Shareholders have been advised that the
Underwriters propose to offer the shares of Common Stock directly to the public
at the public offering price set forth on the cover page of this Prospectus, and
to certain selected dealers (who may include the Underwriters) at such public
offering price less a selling concession not in excess of $0.48 per share. The
selected dealers may reallow a concession not in excess of $0.10 per share to
certain brokers and dealers. After the public offering, the public offering
price, the concession to selected dealers and the reallowance may be changed by
the Underwriters.
 
     The Company and the Selling Shareholders have agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act and to contribute to payments that the Underwriters may be
required to make in respect thereof.
 
     The Company has granted to the Underwriters an option to purchase up to an
aggregate of 600,000 shares of Common Stock, exercisable solely to cover
over-allotments, at the offering price to the public less the underwriting
discounts and commissions shown on the cover page of this Prospectus. Such
option may be exercised at any time until 30 days after the date of the
Underwriting Agreement. To the extent that the option is exercised, each
Underwriter will be committed, subject to certain conditions, to purchase a
number of the additional shares of Common Stock proportionate to such
Underwriter's initial commitment as indicated in the preceding table.
 
     Certain shareholders of the Company, owning an aggregate of 2,835,000
shares after the offering, have agreed that they will not, subject to certain
limited exceptions, directly or indirectly, offer, sell or otherwise dispose of
any shares of Common Stock or any securities convertible into or exchangeable or
exercisable for any such shares for a period of 180 days after the effective
date of the offering without the prior written consent of Lehman Brothers Inc.
In addition, the Company has agreed that it will not, subject to certain limited
exceptions, directly or indirectly, offer, sell or otherwise dispose of any
shares of Common Stock or any securities convertible into or exchangeable for
such shares without the prior written consent of Lehman Brothers Inc. for 180
days after the effective date of the offering.
 
     Until the distribution of the Common Stock is completed, rules of the
Commission may limit the ability of the Underwriters and certain selling group
members to bid for and purchase shares of Common Stock. As an exception to these
rules, the Representatives are permitted to engage in certain transactions that
stabilize the price of the Common Stock. Such transactions may consist of bids
or purchases for the purpose of pegging, fixing or maintaining the price of the
Common Stock.
 
                                       41
<PAGE>   42
 
     In addition, if the Representatives over-allot (i.e., if they sell more
shares of Common Stock than are set forth on the cover page of this Prospectus),
and thereby create a short position in the Common Stock in connection with the
offering, the Representatives may reduce that short position by purchasing
Common Stock in the open market. The Representatives also may elect to reduce
any short position by exercising all or part of the over-allotment option
described herein.
 
     The Representatives also may impose a penalty bid on certain Underwriters
and selling group members. This means that if the Representatives purchase
shares of Common Stock in the open market to reduce the Underwriters' short
position or to stabilize the price of the Common Stock, they may reclaim the
amount of the selling concession from the Underwriters and selling group members
who sold those shares as part of the offering.
 
     In general, purchases of a security for the purpose of stabilization or to
reduce a syndicate short position could cause the price of the security to be
higher than it might otherwise be in the absence of such purchases. The
imposition of a penalty bid might have an effect on the price of a security to
the extent that it were to discourage resales of the security by purchasers in
the offering.
 
     Neither the Company nor any of the Underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the Common Stock. In addition, neither
the Company nor any of the Underwriters makes any representation that the
Representatives will engage in such transactions or that such transactions, once
commenced, will not be discontinued without notice.
 
                                 LEGAL MATTERS
 
     The validity of the shares of Common Stock being offered hereby and certain
other matters are being passed upon for the Company by Kimball, Parr, Waddoups,
Brown & Gee, Salt Lake City, Utah. Certain legal matters relating to the
offering will be passed upon for the Underwriters by Akin, Gump, Strauss, Hauer

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Bedford Consultants, Inc.:
 
     We have audited the accompanying balance sheet of Bedford Consultants, Inc.
(a California corporation), as of January 31, 1997, and the related statements
of income and retained earnings, and cash flows for the year then ended. 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 audit.
 
     We conducted our audit 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 audit provides 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 Bedford Consultants, Inc. as
of January 31, 1997, and the results of its operations and its cash flows for
the year then ended in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Nature of Operations and Organization of Business
 
     Bedford Consultants, Inc. (the "Company") was incorporated under the laws
of the state of California. The Company provides professional services to
companies in need of temporary professionals with experience in information
technology, software engineering and technical writing. The Company's primary
service area is Northern California.
 
     In April 1997, the Company signed an agreement to sell its outstanding
common stock and substantially all of the operations of the Company to SOS
Staffing Services, Inc., which assumed control of the operations of the Company
on July 1, 1997. The accompanying financial statements presented are
pre-acquisition financial statements of the Company and do not reflect any
purchase accounting adjustments.
 
  Revenue Recognition
 
     Service revenues are recognized at the time the professional services are
provided.
 
  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 as of the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Cash and Cash Equivalents
 
     The Company considers highly liquid investments with an original maturity
of three months or less to be cash and cash equivalents. As of June 30, 1997,
included in cash and cash equivalents was a money market account of
approximately $211,992 with an investment company.
 
  Property and Equipment
 
     Property and equipment are stated at cost and depreciated using declining
balance methods over their estimated useful lives. The depreciation and
amortization periods range from five to seven years.
 
     Upon retirement or other disposition of property and equipment, the cost
and related accumulated depreciation or amortization is removed from the
accounts. The resulting gain or loss is reflected in income. Major renewals and
betterments are capitalized while minor expenditures for maintenance and repairs
are charged to expense as incurred.
 
  Income Taxes
 
     The Company recognizes deferred tax assets or liabilities for expected
future tax consequences of events that have been recognized in the financial
statements or tax returns. Under this method, deferred tax assets or liabilities
are determined based upon the difference between financial and income tax bases
of assets and liabilities using enacted tax rates expected to apply when
differences are expected to be settled or realized.
 
  Unaudited Interim Financial Data
 
     The accompanying unaudited financial statements as of June 30, 1997 and for
the five months ended June 30, 1996 and 1997 have been prepared in accordance
with generally accepted accounting principles for interim financial information.
In the opinion of management, all adjustments (consisting of normal recurring
 
                                       F-6

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
adjustments) considered necessary for a fair presentation have been included.
Operating results for the five months ended June 30, 1997 are not necessarily
indicative of the results that may be expected for the full year.
 
  Concentration of Credit Risk and Significant Customers
 
     Financial instruments that potentially subject the Company to credit risk
consist principally of trade receivables. In the normal course of business, the
Company provides credit terms to its customers. The Company performs ongoing
credit evaluations of its customers but does not require collateral.
 
     For the year ended January 31, 1997, two customers accounted for
approximately 22 and 13 percent of total revenues. For the five months ended
June 30, 1997, three customers accounted for approximately 16, 12 and 11 percent
of total revenues, and for the five months ended June 30, 1996 three customers
accounted for approximately 27, 13 and 10 percent of total revenues.
 
NOTE 2. OPERATING LEASE COMMITMENTS
 
     The Company leases office facilities and equipment under noncancellable
operating leases. For the year ended January 31, 1997 lease expense totalled
approximately $158,000. For the five months ended June 30, 1996 and June 30,
1997 lease expense totalled approximately $60,000 and $72,000, respectively.
 
     Future minimum lease payments under noncancellable operating leases are as
follows:

To Execusoft, Inc.:
 
     We have audited the accompanying balance sheet of Execusoft, Inc. (a
California corporation), as of December 31, 1996, and the related statements of

our audit.
 
     We conducted our audit 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 audit provides 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 Execusoft, Inc. as of

                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Nature of Operations and Organization of Business
 
     Execusoft, Inc. (the "Company") was incorporated under the laws of the
state of California. The Company provides professional contract software
consulting services to many industries in the public and private sectors located
throughout the western United States. In addition, the Company provides
permanent placement services.
 
     In August 1997, the Company signed an agreement to sell certain assets and
substantially all of the operations of the Company to SOS Staffing Services,
Inc., which assumed control of the operations of the Company on August 25, 1997.
The accompanying financial statements presented are pre-acquisition financial
statements of the Company and do not reflect any purchase accounting
adjustments.
 
  Accounting Period
 
     The Company's fiscal year ends on December 31 each year. For interim
reporting purposes the Company utilizes a weekly closing period. The twenty-four
weeks ended June 15, 1997 represents the period from January 1, 1997 through
June 15, 1997.
 
  Revenue Recognition
 
     Service revenues consist primarily of consulting service revenues and fees
earned on permanent placement services. Consulting service revenues are
recognized when the services are performed. Permanent placement service revenues
are initially deferred when employment candidates accept offers of permanent
employment and are recognized as revenues after the Company's guarantee period
expires which is typically 90 days.
 
  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 as of the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Property and Equipment
 
     Property and equipment are stated at cost and depreciated using the
declining balance method over their estimated useful lives. Leasehold
improvements are amortized over the terms of the respective leases or the
estimated economic lives of the assets, whichever is shorter. The depreciation
and amortization periods range from three to ten years.
 
     Upon retirement or other disposition of property and equipment, the cost
and related accumulated depreciation or amortization is removed from the
accounts. The resulting gain or loss is reflected in income. Major renewals and
betterments are capitalized while minor expenditures for maintenance and repairs
are charged to expense as incurred.
 
  Income Taxes
 
     The Company has elected, for federal and state income tax purposes, to
include its taxable income with that of its shareholders (an S Corporation
election). Accordingly, the Company does not make a provision for federal income
taxes; however the Company was taxed at the rate of 1.5 percent for California
state franchise tax purposes. The Company distributes amounts as needed for the
payment of the shareholders' federal and

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
state income taxes. The Company anticipates making future distributions as
needed for the payment of the shareholders' income taxes.
 
  Unaudited Interim Financial Data
 
     The accompanying unaudited financial statements as of June 15, 1997 and for
the twenty-four weeks ended June 16, 1996 and June 15, 1997 have been prepared
in accordance with generally accepted accounting principles for interim
financial information. In the opinion of management, all adjustments (consisting
of normal recurring adjustments) considered necessary for a fair presentation
have been included. Operating results for the twenty-four weeks ended June 15,
1997 are not necessarily indicative of the results that may be expected for the
full year.
 
  Concentration of Credit Risk and Significant Customers
 
     Financial instruments that potentially subject the Company to credit risk
consist principally of trade receivables. In the normal course of business, the
Company provides credit terms to its customers. The Company performs ongoing
credit evaluations of its customers but does not require collateral.
 
     For the year ended December 31, 1996, one customer accounted for
approximately 12 percent of total revenues. For the twenty-four weeks ended June
15, 1997, three customers accounted for 18, 12 and 10 percent of total revenues.
 
NOTE 2. OPERATING LEASE COMMITMENTS
 
     The Company leases certain office facilities and equipment under
noncancellable operating leases. For the year ended December 31, 1996 lease
expense totalled approximately $89,900. For the twenty-four weeks ended June 16,
1996 and June 15, 1997 lease expense totalled approximately $42,200 and $35,800,
respectively.
 
     Future minimum lease payments under noncancellable operating leases are as
follows:

                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Nature of Operations and Organization of Business
 
     JesCo Technical Services, Inc. (the "Company") was incorporated under the
laws of the state of Washington. The Company provides professional information
technology outsourcing and consulting services primarily to cellular
communication companies in Washington and California on a broad range of
technical and business matters.
 
     In September 1997, the Company signed an agreement to sell certain assets
and substantially all of the operations of the Company to SOS Staffing Services,
Inc., which, assuming all conditions to closing are met, will assume control of
the operations of the Company on October 1, 1997. The accompanying financial
statements presented are pre-acquisition financial statements of the Company and
do not reflect any purchase accounting adjustments.
 
  Revenue Recognition
 
     Revenues consist of outsourcing and consulting service revenues, which are
negotiated on a fixed-fee basis or an actual-time-incurred basis. Revenues are
recognized when the services are performed.
 
  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 as of the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Property and Equipment
 
     Property and equipment are stated at cost and depreciated using the
straight-line method over their estimated useful lives of five years.
 
     Upon retirement or other disposition of property and equipment, the cost
and related accumulated depreciation or amortization is removed from the
accounts. The resulting gain or loss is reflected in income. Major renewals and
betterments are capitalized while minor expenditures for maintenance and repairs
are charged to expense as incurred.
 
  Income Taxes
 
     The Company has elected, for federal and state income tax purposes, to
include its taxable income with that of its shareholder (an S Corporation
election). Accordingly, the Company does not make a provision for income taxes.
The Company distributes amounts as needed for the payment of the shareholder's
income taxes. The Company anticipates making future distributions as needed for
the payment of the shareholder's income taxes.
 
  Unaudited Interim Financial Data
 
     The accompanying unaudited financial statements as of June 30, 1997 and for
the six months ended June 30, 1996 and 1997 have been prepared in accordance
with generally accepted accounting principles for interim financial information.
In the opinion of management, all adjustments (consisting of normal recurring
adjustments) considered necessary for a fair presentation have been included.
Operating results for the six months ended June 30, 1997 are not necessarily
indicative of the results that may be expected for the full year.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
  Concentration of Credit Risk and Significant Customers
 
     Financial instruments that potentially subject the Company to credit risk
consist principally of trade receivables. In the normal course of business, the
Company provides credit terms to its customers. The Company performs ongoing
credit evaluations of its customers but does not require collateral.
 
     For the year ended December 31, 1996, two customers accounted for
approximately 71 and 15 percent of total revenues. For the six months ended June
30, 1997, three customers accounted for approximately 34, 24, and 23 percent of
total revenues.
 
     On April 1, 1997, the Company entered into a master service outsourcing
agreement with a cellular communications service provider (the "Provider").
Under the terms of the agreement, the Company agrees to support the Provider's
computer operations and sustain the Provider's business applications from June
1, 1997 through December 31, 1998 with potential renewals thereafter. The
Provider has the option to terminate the agreement at its convenience by giving
a minimum of 90 days notice and by paying early termination fees as set forth in
the agreement. The Provider can also terminate the agreement early if service
level objectives specified in the agreement are not met. The agreement provides
for fixed monthly fees to be paid to the Company along with increases or
reductions in the amounts under certain circumstances as described in the
agreement.
 
NOTE 2. OPERATING LEASE COMMITMENTS
 
     The Company has entered into several noncancellable operating lease
agreements for the use of certain office facilities and equipment.
 
     Future minimum lease payments under noncancellable operating leases are as
follows:

</TABLE>
 
     For the year ended December 31, 1996 lease expense totalled approximately
$15,500. For the six months ended June 30, 1996 and 1997 lease expense totalled
approximately $7,200 and $19,600, respectively.
 
NOTE 3. EMPLOYEE BENEFIT PLAN
 
     The Company sponsors a 401(k) plan for all employees who have completed six
months of service and are at least 21 years of age. The plan provides for
discretionary employer contributions. No employer contributions have been made
to the plan.
 
NOTE 4. LINE OF CREDIT
 
     In July 1997 the Company obtained a line of credit with a bank which allows
for maximum borrowing of $750,000. Borrowings under the line of credit accrue
interest at the bank's prime rate plus .5 percent (9 percent as of June 30,
1997). Borrowings are secured by substantially all accounts receivables and are
guaranteed by the shareholder. The agreement contains certain restrictive
financial covenants, including minimum levels of tangible net worth and cash
flow coverage.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Telecom Project Assistance, Inc.:
 
     We have audited the accompanying balance sheet of Telecom Project
Assistance, Inc. (a California corporation), as of December 31, 1996, and the
related statements of income and retained earnings, and cash flows for the year
then ended. 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 audit.
 
     We conducted our audit 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 audit provides 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 Telecom Project Assistance,
Inc. as of December 31, 1996 and the results of its operations and its cash
flows for the year then ended in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Nature of Operations and Organization of Business
 
     Telecom Project Assistance, Inc. (the "Company") was incorporated under the
laws of the state of California. The Company provides professional
telecommunications consulting services to companies located primarily in
Northern California.
 
     In June 1997, the Company signed an agreement to sell certain assets and
substantially all of the operations of the Company to SOS Staffing Services,
Inc., which assumed control of the operations of the Company on July 1, 1997.
The accompanying financial statements presented are pre-acquisition financial
statements of the Company and do not reflect any purchase accounting
adjustments.
 
  Revenue Recognition
 
     Service revenues consist primarily of consulting service revenues and are
recognized when the services are performed.
 
  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 as of the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Property and Equipment
 
     Property and equipment are stated at cost and depreciated using the
straight-line method over their estimated useful lives. The depreciation and
amortization periods range from three to seven years.
 
     Upon retirement or other disposition of property and equipment, the cost
and related accumulated depreciation or amortization is removed from the
accounts. The resulting gain or loss is reflected in income. Major renewals and
betterments are capitalized while minor expenditures for maintenance and repairs
are charged to expense as incurred.
 
  Income Taxes
 
     The Company has elected, for federal and state income tax purposes, to
include its taxable income with that of its shareholders (an S Corporation
election). Accordingly, the Company does not make a provision for federal income
taxes; however the Company is required to pay California state franchise tax.
The Company distributes amounts as needed for the payment of the shareholders'
federal and state income taxes.
 
  Unaudited Interim Financial Data
 
     The accompanying unaudited financial statements as of June 30, 1997 and for
the six months ended June 30, 1996 and 1997 have been prepared in accordance
with generally accepted accounting principles for interim financial information.
In the opinion of management, all adjustments (consisting of normal recurring
adjustments) considered necessary for a fair presentation have been included.
Operating results for the six months ended June 30, 1997 are not necessarily
indicative of the results that may be expected for the full year.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
  Concentration of Credit Risk and Significant Customers
 
     Financial instruments that potentially subject the Company to credit risk
consist principally of trade receivables. In the normal course of business, the
Company provides credit terms to its customers. The Company performs ongoing
credit evaluations of its customers but does not require collateral.
 
     For the year ended December 31, 1996, two customers accounted for
approximately 16 and 15 percent of total revenues. For the six months ended June
30, 1997, one customer accounted for approximately 29 percent of total revenues.
 
NOTE 2. OPERATING LEASE COMMITMENT
 
     The Company leases its office facility under a noncancellable operating
lease. For the year ended December 31, 1996 lease expense totalled approximately
$46,600. For the six months ended June 30, 1996 and 1997 lease expense totalled
approximately $20,700 and $27,700, respectively.
 
     Future minimum lease payments under noncancellable operating leases are as
follows:

</TABLE>
 
NOTE 3. CONTINGENCIES
 
     From time to time the Company is involved in legal matters generally
incident to its business. It is the opinion of management after discussion with
legal counsel, that the ultimate dispositions of these matters will not have a
material impact on the financial condition, liquidity or results of operations
of the Company.
 
NOTE 4. LINE OF CREDIT
 
     The Company had an equipment line of credit with a bank which accrued
interest at the bank's prime rate plus 1.25 percent (10 percent as of December
31, 1996). The agreement expired June 1997.
 
NOTE 5. EMPLOYEE BENEFIT PLAN
 
     The Company sponsors a 401(k) benefit plan for all employees who have
completed 1,000 hours of service. Effective for 1997, the plan provides for
employer matching contributions equal to 50% of an employee's contribution up to
3% of the employee's compensation. The plan also allows for other discretionary
employer matching contributions. For the six months ended June 30, 1997,
employer matching contributions totalled approximately $7,000.
