                                  THE COMPANY
 
     CORESTAFF is one of the largest information technology ("IT") services and
staffing firms in the United States. The Company provides a broad range of IT
services and staffing services to a diverse client base through its network of
147 branch offices in the United States, the United Kingdom and India. The
Company's principal clients include companies such as American Express, AT&T,
Compaq Computer, CSX, Lucent Technologies, MCI and Mobil.
 
     The Company's services are provided through its two business groups: the IT
Services Group, which is comprised of COMSYS Information Technology Services
("COMSYS") and the recently formed IT Solutions unit ("IT Solutions"), and the
Staffing Services Group, which operates under the name "CORESTAFF Services."
COMSYS provides highly skilled IT consultants principally to FORTUNE 1000
companies and governmental agencies. COMSYS has more than 4,000 consultants on
assignments and supports all major computer technology platforms (mainframe,
mid-range, client/server and network) and supports client projects using a
variety of software applications. COMSYS maintains a database of approximately
170,000 consultants from which it recruits consultants to support client
projects. For the quarter ended March 31, 1997, COMSYS accounted for 45.8% and
51.6% of the Company's pro forma revenues and gross profit, respectively. The
Company's IT Solutions unit provides technologically advanced resources and
solutions, encompassing systems integration, software development, legacy
application support and outsourcing services. Formed during the first quarter of
1997, IT Solutions accounted for 3.1% and 5.1% of the Company's pro forma
revenues and gross profit, respectively, for the quarter ended March 31, 1997.
Management expects the growth of IT Solutions to exceed that of the Company's
other business units and to provide an increasing percentage of revenues and
profits for the Company. CORESTAFF Services provides office support, light
industrial and specialized staffing services to local, regional and national
customers. CORESTAFF Services accounted for 51.1% and 43.3% of the Company's pro
forma revenues and gross profit, respectively, for the quarter ended March 31,
1997.
 
     Since its inception in July 1993, the Company has grown through the
acquisition of IT services and staffing businesses and through substantial
internal growth. As of June 30, 1997, the Company had acquired 32 businesses,
including 17 in the IT Services Group and 12 in the Staffing Services Group. The
Company's revenues and operating income have increased from $163.4 million and
$4.9 million, respectively, in 1994 to $596.1 million and $36.7 million,
respectively, in 1996. For the quarter ended March 31, 1997, the Company's
revenues and operating income increased to $216.9 million and $12.2 million as
compared to $103.4 million and $5.8 million for the period ended March 31, 1996,
representing revenue and operating income growth of 109.8% and 110.3%,
respectively.
 
STRATEGY
 
     The Company seeks to expand on its success by broadening the range of IT
services and staffing services offered to its existing and prospective clients.
The Company's strategy is focused on internal growth, selective acquisitions,
and the continued development of additional complementary IT services and
staffing services. The Company believes that its business strategy will provide
it with a competitive advantage in pursuing and
                                        3
<PAGE>   7
 
maintaining major national and regional accounts as well as in serving local
markets. The key elements of the Company's strategy are presented below.
 
     Enhance Leadership Position in the Information Technology Services Sector.
In recent years, there has been a dramatic increase in demand for technical
project support, software development, and other IT services resulting from the
increased use of technology. This high level of demand, coupled with the high
value-added nature of such services, generally results in higher profit margins.
The Company has targeted the high-growth, high-margin IT services sector as its
primary growth area and intends to aggressively enhance its existing leadership
position in this sector.
 
     The Company established its IT Services Group with the acquisition of two
major businesses in September 1994 and June 1995. Since that time, the Company
has acquired 15 additional IT services businesses, including three IT solutions
businesses. As part of its strategy to offer a more complete range of high end,
value-added IT services to its clients, the Company formed its IT Solutions unit
in the first quarter of 1997. The Company believes that it is a leading provider
of IT staff augmentation services, with 1996 pro forma revenues of $374 million.
In 1996, pro forma revenues for the IT Services Group increased 32% over 1995,
reflecting internal growth, while increasing gross margins. The Company expects
that revenues contributed by this group will continue to increase as a
percentage of its total revenues.
 
     The Company believes that it is well positioned to capitalize on the
anticipated continued growth in the IT services sector due to its size,
geographic breadth, industry experience, and expertise in providing a wide range
of IT services. The Company intends to grow significantly in this area through
(i) selective acquisitions, (ii) aggressive recruiting, training, and marketing
of industry specialists with a wide range of technical expertise, (iii) opening
offices in new and existing markets, and (iv) active cross-selling of its IT
services to its existing IT and staffing services customers. The Company intends
to continue pursuing businesses with specializations in custom software
development, packaged software implementation, critical computer code
maintenance and network implementation and integration.
 
     Leverage Infrastructure and Existing Client Base for Internal Growth. The
Company has established a national branch network for its IT Services Group and
Staffing Services Group and has used this network to increase revenues and
enhance earnings stability. The Company believes that this geographic and sector
diversity helps to protect it from adverse regional economic and business
cycles. In addition, the Company's existing branch office network has the
infrastructure and support systems in place to enable it to expand and enhance
services while limiting additional expense. This allows the Company to achieve
significant economies through the allocation of management, advertising,
recruiting and training costs over a larger revenue base. Further economies of
scale are presented by the Company's three domestic and three international
development centers established to provide offsite software development services
for clients.
 
     The Company's branch office network, together with its software development
centers, provides it with an advantage when pursuing contracts with national
accounts. These accounts generally have numerous locations and a wide variety of
service needs. The Company's ability to meet the broad service requirements of
its clients provides a basis for establishing long-term relationships with
large-scale users of IT services and staffing services, and further provides the
Company with significant advantages over its competitors in marketing solutions
to such clients.
 
     Broaden Range of Value-added IT Services and Solutions. The Company
believes that it can increase its revenues from existing clients and attract new
clients by offering a broad range of IT services through its IT Services Group.
The IT Services Group is comprised of COMSYS, which addresses IT staff
augmentation requirements, and IT Solutions, which addresses specific IT
problems. In response to the rapidly changing nature of IT, the Company
regularly evaluates emerging technologies and their potential benefit as new
services to clients. Based on these evaluations, the Company may develop or
expand the service lines of existing business units or acquire complementary
businesses to enhance the Company's ability to support its clients' ongoing IT
requirements. IT Solutions is a recent addition to the service line that
provides value-added services, including Internet/Intranet services, Year 2000
solutions, new media solutions (such as multimedia-based Web site design),
software development, training services, critical code maintenance and software
testing and quality assurance.

     Expand Use of Offshore Development Centers. In 1997, the Company acquired
three offshore software development centers in India which will provide the IT
Services Group with a significant cost advantage as well as the ability to
provide 24-hour service to its clients. The Company's costs in India are
significantly lower than costs incurred for comparable resources in the U.S.
Through satellite communications, the Company's clients may be directly linked
to the IT Services Group's facilities in India. Due to the time difference
between India and the U.S., the Company can create a virtual "second shift" for
its North American clients allowing for more rapid completion of projects and
off-peak use of clients' technology resources. In addition, for larger projects
with critically short time frames, the offshore facilities allow the Company to
parallel process many of its development phases to accelerate delivery time. The
Company intends to continue to seek opportunities to further use its facilities
in India as well as evaluate other offshore facilities that could provide
similar cost advantages.
 
     Continue to Pursue Selective Acquisitions. The Company has made 32
acquisitions since its inception in 1993. While the Company initially
concentrated its acquisition efforts on establishing a national base of staffing
services, the Company has more recently focused its acquisition efforts in the
higher-margin IT services sector. The Company is currently focused on
acquisitions to expand the services offered by COMSYS and IT Solutions. Through
June 30, 1997, the Company had acquired five businesses in its IT Services Group
with aggregate 1996 revenues of $49.0 million. Currently, the Company has
non-binding letters of intent to acquire three businesses, which would
complement its existing IT businesses.
 
     Focus on Recruiting, Training and Retention. The Company believes that its
ability to attract and retain a broad spectrum of high-quality employees,
consultants and computer professionals is a key element of its growth strategy.
The Company has established a domestic and international network to recruit
employees, consultants and computer professionals of all experience levels. The
Company has 12 full time employees dedicated to recruiting in India as well as
two full-time recruiters located in the U.K. In the IT Services Group, the
Company provides continual training opportunities in software engineering
techniques and key technologies. The Company has made significant investments in
its domestic and foreign training centers, including centers that employ
full-time instructors and are equipped with client/server and mainframe
hardware, software and development tools. These training resources enhance the
Company's ability to provide qualified IT professionals to satisfy its client
needs. In addition, the Company's complementary services from staff augmentation
to high-end software development offer its IT professionals the opportunity to
grow professionally within the Company. The Company believes that this internal
upward mobility is a critical factor in continuing to attract and retain
high-quality employees, consultants and computer professionals.
 
          THE INFORMATION TECHNOLOGY SERVICES AND STAFFING INDUSTRIES
 
     According to International Data Corporation ("IDC"), the worldwide market
for IT services was estimated at $202 billion in 1996, with a projected market
of $292 billion in 2000. IDC also projects that the domestic IT services market
will grow from $84 billion in 1996 to $130 billion in 2000. Currently,
substantially all of the Company's revenues from its IT Services Group are
derived from IT staff augmentation services and IT implementation and
integration services, two segments within the overall IT services industry. IDC
estimates that the domestic market for IT implementation and integration
services was $22 billion in 1996, with a forecast of $35 billion by 2000.
According to the Staffing Industry Report, a staffing service industry
publication, the domestic market for technical/IT staff augmentation services
was approximately $12 billion in 1996 and grew at a compounded annual rate of
approximately 20% over the past five years.
 
     According to the Staffing Industry Report, the U.S. staffing industry was
estimated to have 1996 revenues of approximately $47.1 billion and a compound
annual growth rate of approximately 17% over the past five years. Within the
staffing industry, the office/clerical/industrial sector was estimated to have
1996 revenues of approximately $26.4 billion and a compounded annual growth rate
of 17% over the past five years. The Company believes that the demand for IT
staff augmentation and staffing services will continue to increase due to
changes in workforce lifestyles, advances in technology and the increasing
desire of many companies to shift employee costs from a fixed to a variable
expense and to outsource the support functions.

                                  RISK FACTORS
 
     In addition to other information contained in this Prospectus, the
following risk factors should be considered carefully in evaluating an
investment in the securities offered by this Prospectus.
 
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 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 temporary and IT
professionals, to expand into new markets, and to maintain profit margins in the
face of pricing pressures.
 
NO ASSURANCE OF SUCCESSFUL MANAGEMENT AND MAINTENANCE OF GROWTH
 
     The Company has experienced rapid growth, primarily through acquisitions.
The Company's financial results and prospects depend in large part on its
ability to successfully integrate, manage and maintain the operating
efficiencies and productivity of these acquired operations. In particular,
whether the anticipated benefits of acquired operations are ultimately achieved
will depend on a number of factors, including the ability of the combined
companies to maintain low administrative costs, successfully combine markets
targeted and services offered, general economies of scale and the ability of the
Company, generally, to capitalize on its combined service and marketing base and
strategic position. Moreover, the ability of the Company to continue to grow
will depend on a number of factors, including competition from other IT services
and staffing companies, availability of capital, ability to maintain margins,
ability to recruit and train additional qualified personnel and the management
of costs in a changing technological environment. There can be no assurance that
the Company will be able to continue to expand and successfully manage its
growth.
 
     In addition, there can be no assurance that the Company will continue to be
able to expand its market presence in its current locations or to successfully
enter other markets or integrate acquired businesses into its operations. The
ability of the Company to continue its growth will depend on a number of
factors, including existing and emerging competition, the availability of
attractive acquisition opportunities and working capital to support such growth,
the ability of the Company to consummate such acquisition opportunities. The
Company must also manage costs in a changing technological environment,
continually adapt its infrastructure and systems to accommodate growth, and
recruit and train additional qualified personnel.
 
ABILITY TO CONTINUE ACQUISITION STRATEGY
 
     The Company plans to continue to pursue opportunities to expand through
acquisitions. The Company's acquisition strategy involves certain potential
risks associated with assessing, acquiring and integrating the operations of
acquired companies. Although the Company generally has been successful in
implementing its acquisition strategy, there can be no assurance that attractive
acquisition opportunities will continue to be available, that the Company will
have access to the capital required to finance potential acquisitions on
satisfactory terms, or that any businesses acquired will prove profitable.
Future acquisitions may result in the incurrence of additional indebtedness or
the issuance of additional equity securities.
 
ABILITY TO ATTRACT AND RETAIN QUALIFIED IT PROFESSIONALS
 
     The Company's continued success in its IT Services Group will depend in
large part upon its ability to attract, retain and motivate highly-skilled
employees, particularly project managers and client partners and
 
                                        8
<PAGE>   12
 
other senior technical personnel. Qualified project managers are in particularly
great demand and are likely to remain a limited resource for the foreseeable
future. However, the Company believes that it has been successful in its efforts
to attract, develop and retain the number of high-quality professionals needed
to support present operations and future growth, in part because of its emphasis
on training and its policy of promoting from within. Although the Company
expects to continue to attract sufficient numbers of highly skilled employees
and to retain its existing project managers and other senior personnel for the
foreseeable future, there can be no assurance that the Company will be able to
do so.
 
RAPID TECHNOLOGICAL CHANGE; DEPENDENCE ON NEW SOLUTIONS
 
     The Company's success will depend in part on its ability to develop IT
solutions that keep pace with continuing changes in IT, evolving industry
standards and changing client preferences. There can be no assurance that the
Company will be successful in adequately addressing these developments on a
timely basis or that, if these developments are addressed, the Company will be
successful in the marketplace. In addition, there can be no assurance that
products or technologies developed by others will not render the Company's
services uncompetitive or obsolete. The Company's failure to address these
developments could have a material adverse effect on the Company's business,
operating results and financial condition.
 
FIXED-BID PROJECTS
 
     The Company undertakes certain IT projects billed on a fixed-bid basis,
which is distinguishable from the Company's principal method of billing on a
time and materials basis, and undertakes other projects on a fee-capped basis.
The failure of the Company to complete such projects within budget or below the
cap would expose the Company to risks associated with cost overruns, which could
have a material adverse effect on the Company's business, operating results and
financial condition.
 
GOVERNMENT REGULATION OF IMMIGRATION
 
     Certain of the Company's IT consultants are foreign nationals working in
the United States under H-1B permits. Accordingly, both the Company and these
foreign nationals must comply with United States immigration laws. The inability
of the Company to obtain H-1B permits for certain of its employees in sufficient
quantities or at a sufficient rate could have a material adverse effect on the
Company's business, operating results and financial condition. Furthermore,
Congress and administrative agencies with jurisdiction over immigration matters
have periodically expressed concerns over the levels of legal and illegal
immigration into the U.S. These concerns have often resulted in proposed
legislation, rules and regulations aimed at reducing the number of work permits
that may be issued. Any changes in such laws making it more difficult to hire
foreign nationals or limiting the ability of the Company to retain foreign
employees could require the Company to incur additional unexpected labor costs
and expenses. Any such restrictions or limitations on the Company's hiring
practices could have a material adverse effect on the Company's business,
operating results and financial condition. See "Business -- Employees."
 
LIABILITIES FOR CLIENT AND EMPLOYEE ACTIONS
 
     Temporary service providers are in the business of employing people and
placing them in the workplace of other businesses. An attendant risk of such
activity includes possible claims of discrimination and harassment, employment
of illegal aliens, and other similar claims. The Company has policies and
guidelines in place to reduce its exposure to these risks. However, a failure to
follow these policies and guidelines may result in negative publicity and the
payment by the Company of monetary damages or fines. Although the Company
historically has not had any significant problems in this area, there can be no
assurance that the Company will not experience such problems in the future.
 
     The Company is also exposed to liability with respect to actions taken by
its employees while on assignment, such as damages caused by employee errors,
misuse of client proprietary information, or theft of client property. To reduce
such exposures, the Company maintains insurance policies covering general
liability, workers' compensation claims, errors and omissions, and employee
theft. Due to the nature of the
 
                                        9
<PAGE>   13
 
Company's assignments, in particular, access to client information systems and
confidential information, and the potential liability with respect thereto,
there can be no assurance that insurance coverage will continue to be available
or that it will be adequate to cover any such liability.
 
RELIANCE ON KEY PERSONNEL
 
     The Company is highly dependent on its management. The Company believes
that its continued success will depend to a significant extent upon the efforts
and abilities of its Chairman, President and Chief Executive Officer, Michael T.
Willis, and certain other key executives. The loss of the services of Mr. Willis
or any of the other key executives could have a material adverse effect upon the
Company.
 
HIGHLY COMPETITIVE MARKETS
 
     The IT services and staffing services industries are highly competitive
with limited barriers to entry. The Company competes in national, regional and
local markets with IT services companies, full service agencies and specialized
temporary services agencies. The market for IT solutions services includes a
large number of competitors, is subject to rapid change and is highly
competitive. Primary competitors in the IT solutions services market include
participants from a variety of market segments, including "Big Six" accounting
firms, systems consulting and implementation firms, application software firms,
service groups of computer equipment companies, facilities management companies,
general management consulting firms and programming companies. Many of the
Company's competitors have significantly greater financial, technical and
marketing resources and greater name recognition than the Company. In addition,
the Company competes with its clients' internal resources, particularly where
these resources represent a fixed cost to the client. Such competition may
impose additional pricing pressures on the Company. The Company expects that the
level of competition will remain high in the future.
 
INTELLECTUAL PROPERTY RIGHTS
 
     The Company's continued success in its IT solutions businesses is dependent
upon its software deployment and methodology and other proprietary intellectual
property rights. The Company relies upon a combination of trade secret,
nondisclosure and other contractual arrangements and technical measures, and
copyright and trademark laws, to protect its proprietary rights. The Company
holds no patents or registered copyrights. The Company generally enters into
confidentiality agreements with its employees, consultants, clients and
potential clients and limits access to and distribution of its proprietary
information. There can be no assurance that the steps taken by the Company in
this regard will be adequate to deter misappropriation of its proprietary
information or that the Company will be able to detect unauthorized use and take
appropriate steps to enforce its intellectual property rights.
 
     The Company's business includes the development of custom software
applications in connection with specific client engagements. Ownership of such
software is generally assigned to the client. In addition, the Company also
develops object-oriented software components that can be reused in software
application development and certain foundation and application software
products, or software "tools," most of which remain the property of the Company.
 
     Although the Company believes that its services and products do not
infringe on the intellectual property rights of others, there can be no
assurance that such a claim will not be asserted against the Company in the
future.
 
RISKS OF DOING BUSINESS IN INTERNATIONAL MARKETS
 
     The Company expects that international operations will account for an
increasingly significant percentage of the Company's operations. As a result,
the Company is subject to a number of risks, including, among other things,
difficulties relating to administering its business globally, managing foreign
operations, currency fluctuations, restrictions against the repatriation of
earnings, export requirements and restrictions, and multiple and possibly
overlapping tax structures. These risks could have a material adverse effect on
the Company's business, results of operations and financial condition. The
failure of the Company to manage growth, attract
 
                                       10
<PAGE>   14
 
and retain personnel, profitably deliver services, or a significant interruption
of the Company's ability to transmit data via satellite, could have a material
adverse impact on the Company's ability to successfully maintain and develop its
international operations and could have a material adverse effect on the
Company's business, operating results and financial condition.
 
     The Company currently has operations in India and expects to establish
additional offshore operations in other countries. Although wage costs in India
are significantly lower than in the U.S. and elsewhere for comparably skilled IT
professionals, wages in India are increasing at a faster rate than in the U.S.
Changes in inflation, interest rates, taxation, regulation or other social,
political, economic or diplomatic developments affecting India could have a
material adverse effect on the Company's business, operating results and
financial condition.
 
FLUCTUATIONS IN THE GENERAL ECONOMY AFFECT DEMAND FOR IT SERVICES AND STAFFING
SERVICES
 
     Demand for IT services and staffing services is significantly affected by
the general level of economic activity. When economic activity increases,
temporary employees are often added before full-time employees are hired.
Similarly, as economic activity slows, many companies reduce their usage of IT
services and temporary employees before undertaking layoffs of full-time
employees. Further, in an economic downturn, the Company may face pricing
pressure from its customers and increased competition from other IT services and
staffing companies that could have a material adverse effect on the Company's
business.

                                USE OF PROCEEDS
 
     The Company will not receive any proceeds from the sale of the Common Stock
offered hereby.
 
                                 NOTES OFFERING
 
     Concurrently with the Stock Offerings, the Company is offering $180 million
aggregate principal amount of      % Convertible Subordinated Notes due 2004.
The net proceeds of the Notes Offering are estimated to be approximately
$     million, after deducting underwriting discounts and estimated expenses.
The Company intends to use all of such net proceeds to repay certain
indebtedness incurred under the Credit Agreement and for general corporate
purposes. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources." The Notes will be
convertible at the option of the holders at any time after 90 days following the
date of original issuance thereof and prior to maturity, unless previously
redeemed, into Common Stock at a conversion rate of      shares per $1,000
principal amount at maturity of the Notes, subject to adjustment. The Company
will be required to offer to purchase the Notes upon a fundamental change, at
declining redemption prices, subject to adjustments in certain events, together
with accrued and unpaid interest to the date of purchase. The Notes will be
subordinated to all existing and future senior indebtedness of the Company. The
closings of the Stock Offerings and the Notes Offering (collectively, the
"Offerings") are not contingent upon each other.
 
                PRICE RANGE OF COMMON STOCK AND DIVIDEND POLICY
 
     The Common Stock has been quoted on the Nasdaq National Market under the
symbol "CSTF" since November 8, 1995. The Company effected two three-for-two
stock splits during 1996 by means of stock dividends of one share of Common
Stock and Class B Non-Voting Common Stock, $.01 par value per share (the
"Non-Voting Common Stock"), for every two shares of Common Stock and Non-Voting
Common Stock, respectively, held of record on March 14, 1996 and September 10,
1996, respectively. The following table sets forth the range of the low and high
closing prices of the Common Stock as reported on the Nasdaq National Market for
the periods indicated and as adjusted for the two stock splits.

     On July 16, 1997, the closing sale price of the Common Stock as reported on
the Nasdaq National Market was $30 1/4.
 
     The Company has not paid any cash dividends on its Common Stock or
Non-Voting Common Stock and does not anticipate doing so for the foreseeable
future. The Company currently intends to retain any earnings to fund the
expansion and development of its business. Any future determination as to the
payment of dividends will be made at the discretion of the Board of Directors of
the Company and will depend upon the Company's operating results, financial
condition, capital requirements, and such other factors as the Board of
Directors deems relevant. In addition, the Company's Credit Agreement generally
limits the payment of cash dividends to 50% of its net income.

                      SELECTED CONSOLIDATED FINANCIAL DATA
 
     The selected historical consolidated financial data were derived from the
Company's Consolidated Financial Statements, which have been audited by Ernst &
Young LLP, independent auditors. The selected historical consolidated financial
data for the three months ended March 31, 1996 and 1997 have been derived from
the unaudited consolidated financial statements of the Company, which in the
opinion of management include all adjustments (consisting of normal recurring
adjustments) necessary for a fair presentation of the periods presented. The
results of operations for the three months ended March 31, 1997 are not
necessarily indicative of the results of operations to be expected for the year.
The selected historical consolidated financial data should be read in
conjunction with Management's Discussion and Analysis of Financial Condition and
Results of Operations included elsewhere herein and the Consolidated Financial
Statements of the Company included elsewhere in this Prospectus and incorporated
herein by reference. The pro forma consolidated financial data give effect to
all businesses acquired by the Company through March 31, 1997 as if such
acquisitions were consummated as of January 1, 1996, but do not give effect to
the Notes Offering. The pro forma results of operations are not necessarily
indicative of the results that would have occurred had the acquisitions been
consummated as of January 1, 1996 or that might be attained in the future.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion should be read in conjunction with the "Selected
Consolidated Financial Data" included elsewhere in this Prospectus and the
Company's Consolidated Financial Statements included elsewhere herein or
incorporated by reference herein.
 
INTRODUCTION
 
     Since its inception in July 1993, the Company's growth has been the result
of acquisitions of businesses primarily in the IT services and staffing services
industries, coupled with high internal growth. Through June 30, 1997, the
Company had completed 32 acquisitions, including 17 in the IT Services Group and
12 in the Staffing Services Group. The remaining three acquisitions were of
physical therapy staffing businesses, a non-core business that was sold by the
Company in January 1997.
 
     All acquisitions completed by the Company have been accounted for under the
purchase method of accounting. Accordingly, the historical Consolidated
Financial Statements of the Company include the operating results of the
acquired businesses from the date of acquisition. Because the Company's
historical consolidated operating results have been significantly affected by
the number, timing and size of the acquisitions, pro forma financial data are
provided herein for a more meaningful period-to-period comparison of the
Company's operating results. The pro forma financial data for the three month
periods ended March 31, 1996 and 1997 have been prepared assuming all
acquisitions completed through March 31, 1997 were consummated as of the
beginning of such periods. The pro forma financial data for the years ended
December 31, 1995 and 1996 have been prepared assuming all acquisitions
completed through December 31, 1996 were consummated as of the beginning of such
periods. The pro forma results of operations are not necessarily indicative of
the 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.

  Comparison of Historical Operating Results for the Three Months Ended March
  31, 1997 with the Three Months Ended March 31, 1996
 
     Summary. Net income for the current quarter increased 115.6% to $5.8
million compared with net income of $2.7 million in the first quarter of 1996.
Earnings per share increased 80.0% to $0.18 per share, up from $0.10 per share
in 1996. The average number of shares outstanding during the current quarter was
18.6% higher than a year ago as a result of the Company's second public equity
offering in May 1996.
 
     Revenues in the current quarter increased 109.8% to $216.9 million from
$103.4 million in the first quarter of 1996. Operating income also increased
110.3% to $12.2 million from $5.8 million in the same period a year ago. Gross
margin for the current quarter was 23.0% compared with 24.9% for the first
quarter of 1996. The lower gross margin primarily resulted from the effects of
acquisitions of lower margin businesses made after March 31, 1996, and a higher
proportion of revenues from large customers. These larger accounts have lower
gross margins than smaller accounts, but higher operating leverage. Despite the
lower gross margin, operating margin for the current quarter was 5.6%, which
equaled the margin for the first quarter of 1996. This was the result of the
higher operating leverage and the higher proportion of revenues from the IT
Services Group, partially offset by the effects of investments in infrastructure
and IT technical practices to support the growth of the Company.
 
     IT Services Group. For the current quarter, the IT Services Group accounted
for 47.4% and 54.6% of the Company's consolidated revenues and gross profit,
respectively, up from 39.1% and 46.1%, respectively, in 1996. These increases
reflect the higher internal growth rate of this group compared with staffing
services and the ten businesses acquired in this sector in 1996.
 
     COMSYS. For the current quarter, COMSYS accounted for 47.1% and 54.2% of
the Company's consolidated revenues and gross profit, respectively, up from
39.1% and 46.1%, respectively, in the first quarter of 1996. Revenues and gross
profit for the current quarter were up 153.1% and 128.1%, respectively, over the
first quarter of 1996. Gross margin for the current quarter was 26.4% compared
with 29.3% for the first quarter of 1996. This reduction was due to a change in
the business mix related to the acquisition of certain lower margin businesses
in 1996 and the higher proportion of revenues from large customers, which have
lower gross margins than smaller accounts, but higher operating leverage.
 
     IT Solutions Unit. During the current quarter, the Company formed a new
business unit, IT Solutions, to provide system integration and consulting
services. This new unit is currently comprised of one IT consulting and systems
integration business acquired in March 1997. The historical results do not
include the acquisition in June 1997 of Millennium Computer Corporation or the
April 1997 acquisition of Business Mgmt. Data, Inc., a California-based IT
solutions business and its India affiliate, Sriven Computer Solutions (Pvt.),
Ltd. (together "BMD").
 
     Staffing Services Group. For the current quarter, the Staffing Services
Group accounted for 52.6% and 45.4% of the Company's consolidated revenues and
gross profit, respectively, down from 58.8% and 51.8%, respectively, in the
first quarter of 1996. Revenues and gross profit for the current quarter were up
87.7% and 69.9%, respectively, over the first quarter of 1996. Gross margin for
the current quarter was 19.8% compared
 
                                       17
<PAGE>   21
 
with 21.9% for the first quarter of 1996. This reduction related to a change in
business mix caused by (i) the acquisition of a low margin staffing services
business in 1997, (ii) the higher proportion of revenues being generated from
the Company's large on-site programs ("VIP programs") and (iii) lower internal
growth of the Company's higher margin businesses. VIP programs have lower gross
margins than the group's other staffing services business, but higher operating
leverage.
 
     Operating Costs and Expenses. Selling, general and administrative ("SG&A")
expenses for 1997 totaled $35.1 million (16.2% of revenues), compared with $18.5
million (17.9% of revenues) for 1996. The increase in SG&A expenses primarily
related to (i) the effects of the acquisitions, (ii) internal growth of the
operating companies post acquisition, (iii) investments made to improve
infrastructure and to develop technical practices in the IT Services Group and
(iv) higher expenses at the corporate level. The SG&A Margin (i.e. SG&A expenses
as a percentage of revenues) for the first quarter of 1997 was 16.2%, which was
lower than 1996 due to (i) higher operating leverage of the operating groups and
(ii) lower corporate-level overhead as a percentage of consolidated revenues.
 
     Depreciation totaled $0.9 million and $0.6 million for the first quarter of
1997 and 1996, respectively. The increase primarily related to the fixed assets
of the businesses acquired and, to a lesser extent, depreciation on capital
expenditures made post-acquisition. Amortization of $1.7 million and $0.8
million for 1997 and 1996, respectively, related to amortization of intangible
assets (goodwill and non-compete agreements) of the businesses acquired.
 
     Non-Operating Costs and Expenses. Interest expense for the current quarter
totaled $2.2 million compared with $1.3 million for 1996. The $0.9 million
increase was primarily due to increased borrowings for acquisitions.
 
     Provision for Income Taxes. The provision for income taxes for the current
quarter was $4.2 million (an effective tax rate of 42.0%), as compared with $1.9
million (an effective tax rate of 42.0%) for 1996. The Company's effective tax
rate includes the effects of state income taxes and the portion of goodwill
amortization not deductible for federal income tax purposes.
 
     Net Income. Due to the factors described above, net income for 1997 was
$5.8 million compared with $2.7 million for 1996. Net income as a percentage of
revenues ("Net Income Margin") increased to 2.7% for the 1997 period, from 2.6%
for 1996.
 
  Comparison of Pro Forma Operating Results for the Three Months Ended March 31,
1997 with the Three   Months Ended March 31, 1996
 
     Summary. Pro forma operating results, which assume all acquisitions
consummated through March 31, 1997, and the sale of the physical therapy
staffing business in January 1997 occurred as of the beginning of the periods
presented, demonstrate the high internal growth rate of the Company's business
units during the current quarter. Pro forma revenues for the current quarter
were $223.3 million, up 30.3% from $171.4 million in the first quarter of 1996.
Pro forma net income rose 79.9% to $6.0 million, or $0.19 per share, compared
with pro forma net income of $3.4 million, or $0.12 per share, in 1996.
 
     IT Services Group. Pro forma revenues and gross profit increased 34.0% and
32.5%, respectively, from the first quarter of 1996.
 
     COMSYS. Pro forma revenues and gross profit for the current quarter
increased 32.6% and 29.7%, respectively, from the first quarter of 1996. These
improvements reflect the continued strong demand for the Company's IT services.
Pro forma gross margin for the current quarter was 26.4% compared with 27.0% for
1996. The lower gross margin primarily related to (i) a higher proportion of
revenues from large accounts, principally telecommunication clients, (ii) higher
bench time caused by delays in certain project work, (iii) one less billing day
in the current quarter and (iv) higher consultant costs.
 
     IT Solutions Unit. Pro forma revenues and gross profit for the current
quarter increased 60.4% and 69.6%, respectively, from the first quarter of 1996.
Pro forma gross margin was 38.6%, compared with 36.5% for the first quarter of
1996. The gross margin for this unit is higher than that for the Company's other
business units due to the higher value-added nature of the services provided.
The growth rate for the unit is also expected to
 
                                       18
<PAGE>   22
 
exceed the Company's other business units. The pro forma results do not include
the acquisition in April 1997 of BMD.
 
     Staffing Services Group. Pro forma revenues and gross profit for the
current quarter increased 26.9% and 21.4%, respectively, from the first quarter
of 1996. These improvements primarily reflect the increase in revenues from the
VIP programs, including new programs that were added in 1997. Pro forma gross
margin for the current quarter was 19.8%, compared with 20.7% for the first
quarter of 1996. The lower gross margin reflects the higher proportion of
revenues from the Company's VIP programs, which have lower gross margins, but
higher operating leverage.
 
     Operating Costs and Expenses. Pro forma SG&A expenses for the first quarter
of 1997 totaled $36.6 million (16.4% of revenues) compared with $28.3 million
(16.5% of revenues) for the first quarter of 1996. The increase in pro forma
SG&A expenses primarily related to (i) internal growth of the operating groups,
(ii) investments made to infrastructure and to develop technical practices in
the IT Services group and (iii) higher expenses at the corporate level. The pro
forma SG&A Margin for 1997 was lower than 1996 due to (i) higher operating
leverage of the operating groups and (ii) lower corporate-level overhead as a
percentage of consolidated revenues. The pro forma SG&A expenses reflect
historical SG&A expenses at the corporate level and therefore do not include the
pro forma effects of personnel additions made subsequent to the beginning of
each period to accommodate the growth of the Company.
 
     Depreciation of $1.0 million and $0.8 million for 1997 and 1996,
respectively, related primarily to the fixed assets of the acquired companies.
Amortization of $1.8 million for both 1997 and 1996 related to amortization of
intangible assets (goodwill and non-compete agreements) related to the
businesses acquired.
 
     Non-Operating Costs and Expenses. Pro forma interest expense for 1997
totaled $2.5 million compared with $4.5 million for 1996. The decrease relates
to lower long-term debt levels as a result of the repayment of indebtedness with
proceeds from the Company's public equity offering in May 1996.
 
     Provision for Income Taxes. The Company's pro forma effective tax rate for
the current quarter was 42.0%, which was also the rate for the first quarter of
1996. The Company's effective tax rate includes the effects of state income
taxes and the portion of goodwill amortization not deductible for federal income
tax purposes.
 
     Net Income. Due to the factors described above, pro forma net income for
the current quarter was $6.0 million compared with $3.4 million for the first
quarter of 1996. The pro forma Net Income Margin for the current quarter was
2.7% compared with 2.0% for 1996.

  Comparison of Historical Operating Results for the Year Ended December 31,
  1996 with the Year Ended December 31, 1995
 
     Summary. Net income for 1996 increased 158.8% to $16.5 million compared
with net income of $6.4 million for 1995. Included in the 1996 results are the
after-tax effects of two one-time charges totaling $2.3 million, or $0.08 per
share, for the (i) write-down of $1.4 million, or $0.05 per share, of the
Company's physical therapy staffing business, a non-core business that was sold
in January 1997, and (ii) an extraordinary loss of $1.4 million ($0.9 million
after income taxes, or $0.03 per share) related to the write-off of deferred
loan costs of a $130 million credit facility that was extinguished in November
1996.
 
     Income before these one-time charges was $18.8 million, an increase of
195.6% over 1995. Earnings per share before one-time charges increased 113.8% to
$0.62 per share from $0.29 per share in 1995. The average number of shares
outstanding during the year was 54.0% higher than 1995 as a result of the
Company's initial public offering (the "IPO") in November 1995 and a second
public offering in May 1996. All share and per share data have been
retroactively adjusted to give effect to two three-for-two stock splits in 1996.
 
     Revenues for 1996 increased 73.0% to $596.1 million from $344.5 million in
1995. Operating income rose 106.2% to $36.7 million from $17.8 million in 1995.
Gross margin for 1996 was 24.3%, or 40 basis points ("BPS") higher than 1995,
due to the increase in the percentage of revenues contributed by the IT Services
 
                                       20
<PAGE>   24
 
Group, as well as higher margins from that group. Operating margin was 6.2%, or
100 BPS higher than 1995, due to the increase in gross margin and improved
operating leverage.
 
     IT Services Group. For 1996, the IT Services group accounted for 43.4% and
50.3% of the Company's consolidated revenues and gross profit, respectively, up
from 29.3% and 34.1%, respectively, in 1995. Revenues and gross profit were up
155.9% and 158.8%, respectively, over 1995. These increases reflect the high
internal growth rate of this group and the Company's focus on acquiring
businesses in the IT sector. Gross margin for 1996 was 28.1%, or 30 BPS above
that for 1995, primarily due to the acquisition of higher margin IT businesses
in the first half of 1996.
 
     Staffing Services Group. For 1996, the Staffing Services group accounted
for 55.2% and 48.3% of the Company's consolidated revenues and gross profit,
respectively, down from 67.9% and 63.2%, respectively, in 1995. Revenues and
gross profit for 1996 were up 40.8% and 34.1%, respectively, over 1995. Gross
margin for 1996 was 21.2%, or 110 BPS lower than 1995, primarily due to (i) the
higher proportion of revenues being generated from the Company's large on-site
VIP programs, (ii) lower internal growth rates of the higher-margin businesses
within the group, and (iii) acquisitions in 1996 of staffing services businesses
having lower margins than the gross margin for the group in 1995.
 
     Operating Costs and Expenses. SG&A expenses for 1996 totaled $100.3 million
(16.8% of revenues), compared with $60.4 million (17.5% of revenues) for 1995.
The increase in SG&A expenses primarily related to (i) the effects of the
acquisitions, (ii) internal growth of the operating companies post-acquisition
and (iii) higher expenses at the corporate level. The SG&A Margin for 1996 was
70 BPS lower than 1995 due to (i) higher operating leverage of the operating
groups and (ii) lower corporate level overhead as a percentage of consolidated
revenues.
 
     Substantially all of the SG&A expenses were incurred by the operating
groups, which reflects the decentralized nature of the Company's operations. The
front office activities (e.g. recruiting, marketing, account management,
placement, etc.) and most of the accounting and administrative activities of the
operating groups are performed at the subsidiary level. SG&A expenses at the
corporate level totaled $6.4 million for 1996 compared with $3.9 million for
1995. Corporate SG&A expenses primarily related to salaries and benefits of
personnel responsible for corporate activities, including its acquisition
program, management and certain marketing, administrative and reporting
responsibilities. The increase in corporate SG&A expenses reflect personnel
additions necessary to accommodate the growth of the Company.
 
     Depreciation and amortization totaled $7.5 million and $4.2 million for
1996 and 1995, respectively. Depreciation totaled $2.9 million and $1.8 million
for 1996 and 1995, respectively. The increase in depreciation primarily related
to the fixed assets of the businesses acquired and, to a lesser extent,
depreciation on capital expenditures made post-acquisition. Amortization of $4.6
million and $2.4 million for 1996 and 1995, respectively, related to
amortization of intangible assets (goodwill and non-compete agreements) related
to the businesses acquired.
 
     Non-Operating Costs and Expenses. Interest expense for 1996 totaled $4.7
million compared with $7.0 million for 1995. The decrease primarily related to
the repayments of indebtedness with proceeds from the IPO in November 1995 and
from the second public offering in May 1996.
 
     Provision for Income Taxes. The provision for income taxes for 1996 was
$13.6 million (an effective tax rate of 43.9%), compared with $4.6 million (an
effective tax rate of 41.9%) for 1995. The higher effective tax rate in 1996
related to effects of the write-down of the Company's physical therapy staffing
business and the increase in the nondeductible portion of business meals and
entertainment. Virtually all of the $1.4 million write-down was not deductible
for income tax purposes due to the Company's low tax basis in the goodwill of
certain of the physical therapy businesses. The increase in the non-deductible
portion of business meals and entertainment related to per diem expenses of IT
consultants on out-of-town assignments.
 
     Net Income. Due primarily to the factors described above, net income for
1996 was $16.5 million compared with $6.4 million for 1995. Net Income Margin
increased to 2.8% for 1996, from 1.8% for 1995.

  Comparison of Pro Forma Operating Results for the Year Ended December 31, 1996
  with the Year Ended December 31, 1995
 
     Summary. Pro forma operating results, which assume all acquisitions
completed through December 31, 1996 were made as of the beginning of the periods
presented, reflect the high internal growth rate of the Company's IT Services
and Staffing Services groups. Pro forma revenues for 1996 were $734.2 million,
up 22.1% from $601.3 million in 1995. Pro forma income before one-time charges
for 1996 increased 249.5% to $21.0 million, or $0.70 per share, compared with
pro forma net income of $6.0 million, or $0.27 per share, for 1995.
 
     IT Services Group. Pro forma revenues and gross profit for 1996 increased
32.0% and 33.1%, respectively, from 1995. These improvements reflect the
continued strong demand for the Company's IT services. Pro forma gross margin
for 1996 was slightly higher than 1995 due primarily to margin expansion in 1996
in certain lower-margin businesses that were acquired in 1996.
 
     Staffing Services Group. Pro forma revenues and gross profit for 1996
increased 15.0% and 13.5%, respectively, from 1995. These improvements primarily
reflect the increase in revenues from VIP programs, including programs that were
added in 1996. Pro forma gross margin for 1996 was 21.2%, or 30 BPS lower than
1995, reflecting the change in business mix related to higher revenues from VIP
programs, which have lower gross margins but higher operating leverage compared
with the group's other staffing services business.
 
     Operating Costs and Expenses. Pro forma SG&A expenses for 1996 totaled
$120.9 million (16.5% of pro forma revenues), compared with $101.7 million
(16.9% of pro forma revenues) for 1995. The increase in SG&A expenses primarily
related to the internal growth of the operating groups and higher expenses at
the corporate level. The pro forma SG&A Margin for 1996 was 40 BPS lower than
1995 due to (i) higher operating leverage of the operating groups and (ii) lower
corporate level overhead as a percentage of consolidated revenues. The pro forma
SG&A expenses reflect historical SG&A expenses at the corporate level and
therefore do not include the pro forma effects of personnel additions made
subsequent to the beginning of each period to accommodate the growth of the
Company.
 
     Depreciation of $3.2 million and $2.6 million for 1996 and 1995,
respectively, related primarily to the fixed assets of the acquired companies.
Amortization of $6.7 million and $6.5 million for 1996 and 1995, respectively,
related to amortization of intangible assets (goodwill and non-compete
agreements) related to the businesses acquired.
 
     Non-Operating Costs and Expenses. Pro forma interest expense for 1996
totaled $12.6 million compared with $24.2 million for 1995. The decrease
primarily related to the repayments of indebtedness with proceeds from the IPO
and from the second public offering in May 1996.
 
     Provision for Income Taxes. The pro forma provision for income taxes for
1996 was $15.2 million (an effective tax rate of 43.7%), compared with $4.5
million (an effective tax rate of 42.8%) for 1995. The higher effective tax rate
in 1996 related to effects of the write-down of the Company's physical therapy
staffing business and the increase in the non-deductible portion of business
meals and entertainment. Virtually all of the $1.4 million write-down was not
deductible for income tax purposes due to the Company's low tax basis in the
goodwill of certain of the physical therapy businesses sold. The increase in the
non-deductible portion of business meals and entertainment related to per diem
expenses of IT consultants on out-of-town assignments.
 
     Net Income. Due primarily to the factors described above, pro forma net
income for 1996 was $18.7 million compared with $6.0 million for 1995. Pro forma
Net Income Margin was 2.5% for 1996 compared with 1.0% for 1995.

  Comparison of Historical Operating Results for the Year Ended December 31,
  1995 with the Year Ended December 31, 1994
 
     Summary. Revenues, gross profit and net income of the Company for 1995
increased 110.9% to $181.2 million, 143.9% to $48.6 million and 310.4% to $4.8
million, respectively, compared with 1994. This improvement was primarily due to
the effects of acquisitions.
 
     IT Services Group. Prior to 1996, the Company's IT Services group consisted
of two companies, COMSYS Technical Services, Inc. ("COMSYS"), which was acquired
in August 1994 and Cutler-Williams, Incorporated ("Cutler"), which was acquired
in June 1995. Revenues and gross profit for 1995 were $101.1 million and $28.1
million, respectively, compared with $19.2 million and $5.0 million,
respectively, for 1994. This improvement was primarily due to the inclusion of
(i) a full year of operating results for 1995 from COMSYS and (ii) six months of
operating results for 1995 from Cutler. The gross margin of this group increased
to 27.8% for 1995 compared with 26.2% for 1994 primarily due to the higher gross
margin of Cutler as compared with COMSYS.
 
     Staffing Services Group. Revenues and gross profit for 1995 increased by
$98.3 million (72.5%) and $25.4 million (95.3%), respectively, compared with
1994. This improvement was primarily due to the inclusion of (i) a full year of
operating results for 1995 from the three staffing services businesses acquired
in 1994 (the "1994 Acquisitions"), and (ii) the operating results from the date
of acquisition of the four staffing services companies acquired in 1995 (the
"1995 Acquisitions"). Revenues for the 1994 Acquisitions were $135.6 million
from their respective acquisition dates through December 31, 1994, compared with
$204.1 million for the year ended December 31, 1995. Revenues for the 1995
Acquisitions were $29.7 million from their respective acquisition dates through
December 31, 1995. Operating results for 1995 also benefited from a higher gross
margin of 22.3% compared with 19.7% for 1994. This improvement related to (i)
the inclusion of
 
                                       23
<PAGE>   27
 
a full year of operating results for one of the 1994 Acquisitions and a partial
year for 1995 Acquisitions, all three of which had higher gross margins than the
average for the Staffing Services group for 1994, and (ii) improvements in
overall cost performance due to the implementation of risk management
initiatives and the termination of certain low margin accounts.
 
     Operating Costs and Expenses. SG&A expenses for 1995 totaled $60.4 million
(17.5% of revenues), compared with $27.0 million (16.5% of revenues) for 1994.
The increase in SG&A expenses primarily related to (i) the acquisitions, (ii)
internal growth of the operating companies, (iii) higher expenses at the
corporate level and (iv) a $0.7 million nonrecurring charge for payments
incurred in connection with the departure in August 1995 of two officers of an
acquired company.
 
     Substantially all of the SG&A expenses for 1995 were incurred by the
operating groups, which reflects the current decentralized nature of the
Company's operations. The front office activities (e.g. recruiting, marketing,
account management, placement, etc.) and most of the accounting and
administrative activities of the operating companies are performed at the
subsidiary level. SG&A expenses at the corporate level totaled $3.9 million for
1995 compared with $2.1 million for 1994 and related primarily to salaries and
benefits of personnel responsible for corporate activities, including its
acquisition program, management and certain marketing, administrative and
reporting responsibilities. The increase in corporate level SG&A expenses
reflects personnel additions necessary to accommodate the growth of the Company.
 
     Depreciation and amortization totaled $4.2 million and $1.9 million for
1995 and 1994, respectively. Depreciation of $1.8 million and $0.8 million for
1995 and 1994, respectively, related primarily to the fixed assets of the
acquired companies and, to a lesser extent, capital expenditures subsequent to
the acquisition. Amortization of $2.4 million and $1.1 million for 1995 and
1994, respectively, related to amortization of intangible assets (goodwill and
noncompete agreements) related to the businesses acquired.
 
     Non-Operating Costs and Expenses. Interest expense for 1995 totaled $7.0
million compared with $2.3 million for 1994. The $4.7 million increase was a
result of increased borrowings for acquisitions.
 
     Provision for Income Taxes. The provision for income taxes for 1995 was
$4.6 million (an effective tax rate of 41.9%), as compared with $1.2 million (an
effective tax rate of 42.9%) for 1994. The lower effective rate was due to an
increase in income before income taxes that substantially exceeded the increase
in permanent non-deductible expenses.
 
     Net Income. Due primarily to the factors described above, net income for
1995 was $6.4 million compared with $1.5 million for 1994. The Net Income Margin
increased to 1.8% for 1995, from 0.9% for 1994.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company's capital requirements have related to the acquisition of
businesses and capital expenditures. These requirements have been met through a
combination of bank debt, issuances of equity securities and internally
generated funds.
 
     During the first three months of 1997 and 1996, the Company made cash
payments for acquisitions of $25.0 million and $29.8 million, respectively.
Capital expenditures totaled $8.5 million and $1.8 million for the three months
ended March 31, 1997 and 1996, respectively. The Company estimates that its
capital expenditures for 1997 will be approximately $30.0 million. The majority
of these expenditures relate to (i) the installation and development of an
integrated front and back office information system, which is expected to be
operational in 1998, (ii) the roll-out of proprietary software to the staffing
services branches, (iii) up-grading of computer hardware to facilitate the new
integrated information system and new software tools and (iv) furniture,
fixtures and equipment for new offices. The Company expects to fund the
expenditures with cash flows from operations and borrowings under its $250
million Senior Credit Agreement with a syndicate of 12 banks (the "Credit
Agreement").
 
     The Company had working capital of $119.2 million and $94.3 million at
March 31, 1997 and December 31, 1996, respectively. The Company had cash and
cash equivalents of $11.7 million and $6.5 million at March 31, 1997 and
December 31, 1996, respectively. The Company's operating cash flows and
 
                                       24
<PAGE>   28
 
working capital requirements are significantly affected by the timing of payroll
and the receipt of payment from the customer. Generally, the Company pays the
temporary employees of its Staffing Services Group weekly and the employees of
its IT Services Group semi-monthly. Payments from customers are generally
received within 30 to 65 days from the date of invoice. Cash flows provided by
(used in) operating activities were $(6.5) million and $8,000 for the quarter
ended March 31, 1997 and 1996, respectively. The decrease in operating cash
flows for 1997 reflected the significant growth in revenues in the first quarter
of 1997 from a number of the Company's larger accounts, which generally have a
longer billing and collection cycle.
 
     At March 31, 1997, the Company had a $200 million Credit Agreement. Under
terms of the Credit Agreement, the Company could borrow under a revolving credit
facility up to the lesser of $200 million or 3.5 times Pro Forma Adjusted EBITDA
(earnings before interest, income taxes, depreciation and amortization of all
acquired companies for the preceding twelve-month period). Subsequently, the
Company raised the commitment under the Credit Agreement to $250 million.
Borrowings under the Credit Agreement bear interest, at the Company's option, at
LIBOR plus a margin of 0.625% to 1.375%, which depends upon the leverage ratio,
or the bank's base rate. A commitment fee of 0.18% to 0.25%, depending on the
leverage ratio, is payable on the unused portion of the facility. The Credit
Agreement contains certain covenants which, among other things, limit the
payment of dividends and require the maintenance of certain financial ratios. As
of June 30, 1997, the Company had outstanding borrowings under the Credit
Agreement of $216.6 million and remaining availability (after deducting
outstanding letters of credit of $9.3 million) of $24.1 million. The weighted
average interest rate of the Company's outstanding borrowings under the Credit
Agreement was 6.86% at June 30, 1997.
 
     The Company is in the process of amending its Credit Agreement to, among
other things, increase the borrowing capacity under the agreement to the lesser
of $400 million or 4.0 times Pro Forma Adjusted EBITDA. The amended terms also
provide that, after the Notes Offering, the Company's total debt capacity will
be raised from 4.0 times to 4.25 times Pro Forma Adjusted EBITDA and the
borrowing capacity under the Credit Agreement will be lowered to 3.0 times Pro
Forma Adjusted EBITDA. The amended Credit Agreement is expected to be completed
on or before July 31, 1997.
 
     The Company's acquisition program will require significant additional
capital resources. The Company intends to seek additional capital as necessary
to fund such acquisitions through one or more funding sources that may include
borrowings under the Credit Agreement or the issuance of debt or equity
securities or both. Cash flows from operations, to the extent available, may
also be used to fund acquisitions. Although management believes that the Company
will be able to obtain sufficient capital to fund acquisitions, there can be no
assurance that such capital will be available to the Company at the time it is
required or on terms acceptable to the Company.
 
SEASONALITY
 
     The Company's quarterly operating results are affected primarily by the
number of billing days in the quarter and the seasonality of its customers'
businesses. Demand for services in the Staffing Services Group has historically
been lower during the year-end holidays through February of the following year,
showing gradual improvement over the remainder of the year. Although less
pronounced than in the Staffing Services Group, the demand for services of the
IT Services Group is typically lower during the first quarter until customers'
operating budgets are finalized. The Company believes that the effects of
seasonality will be less severe in the future as revenues contributed by the IT
Services Group continue to increase as a percentage of the Company's
consolidated revenues.

                                    BUSINESS
GENERAL
 
     CORESTAFF is one of the largest IT services and staffing firms in the
United States. The Company provides a broad range of IT services and staffing
services to a diverse client base through its network of 147 branch offices in
the United States, the United Kingdom and India. The Company's principal clients
include companies such as American Express, AT&T, Compaq Computer, CSX, Lucent
Technologies, MCI and Mobil.
 
     The Company's services are provided through its two business groups: the IT
Services Group, which is comprised of COMSYS and the recently formed IT
Solutions unit, and the Staffing Services Group, which operates under the name
CORESTAFF Services. COMSYS provides highly skilled IT consultants principally to
FORTUNE 1000 companies and governmental agencies. COMSYS has more than 4,000
consultants on assignments and supports all major computer technology platforms
(mainframe, mid-range, client/server and network) and supports client projects
using a variety of software applications. COMSYS maintains a database of
approximately 170,000 consultants from which it recruits consultants to support
client projects. For the quarter ended March 31, 1997, COMSYS accounted for
45.8% and 51.6% of the Company's pro forma revenues and gross profit,
respectively. The Company's IT Solutions unit provides technologically advanced
resources and solutions, encompassing systems integration, software development,
legacy application support and outsourcing services. Formed during the first
quarter of 1997, IT Solutions accounted for 3.1% and 5.1% of the Company's pro
forma revenues and gross profit, respectively, for the quarter ended March 31,
1997. Management expects the growth of IT Solutions to exceed that of the
Company's other business units and to provide an increasing percentage of
revenues and profits for the Company. CORESTAFF Services provides office
support, light industrial and specialized staffing services to local, regional
and national customers. CORESTAFF Services accounted for 51.1% and 43.3% of the
Company's pro forma revenues and gross profit, respectively, for the quarter
ended March 31, 1997.
 
     Since its inception in July 1993, the Company has grown through the
acquisition of IT services and staffing businesses and through substantial
internal growth. As of June 30, 1997, the Company had acquired 32 businesses,
including 17 in the IT Services Group and 12 in the Staffing Services Group. The
Company's revenues and operating income have increased from $163.4 million and
$4.9 million, respectively, in 1994 to $596.1 million and $36.7 million,
respectively, in 1996. For the quarter ended March 31, 1997, the Company's
revenues and operating income increased to $216.9 million and $12.2 million as
compared to $103.4 million and $5.8 million for the period ended March 31, 1996,
representing revenue and operating income growth of 109.8% and 110.3%,
respectively.
 
THE INFORMATION TECHNOLOGY SERVICES AND STAFFING INDUSTRIES
 
     Information Technology Services. Many businesses today are facing intense
competition, accelerating technological change, personnel downsizing and
widespread business process reengineering. Increasingly, these companies are
turning to IT services and solutions to address these issues and to compete more
effectively. As a result, the ability of an organization to integrate and deploy
new information technologies has become critical. Information technology staff
augmentation services has become one of the fastest growing sectors of the
staffing industry. Over the last decade, the increased use of technology has led
to a dramatic rise in demand for technical project support, software
development, and other computer-related services. Corporations have outsourced
many of these departments and/or have used the employees of IT staff
augmentation firms in an attempt to meet the increased demand for
computer-skilled personnel.
 
     Although many companies have recognized the importance of IT systems and
products to compete in today's business climate, the process of designing,
developing and implementing IT solutions has become increasingly complex.
Companies are continuing to migrate away from centralized mainframes running
proprietary software toward decentralized, scalable architectures based on
personal computers, client/server architectures, local and wide area networks,
shared data bases and packaged application software. These advances have greatly
enhanced the ability of companies to benefit from the application of IT.
Consequently,
 
                                       26
<PAGE>   30
 
the number of companies desiring to use IT in new ways and the number of end
users within these organizations are rising rapidly.
 
     As a result of the variety and complexity of these new technologies, IT
managers must integrate and manage "open systems" and "distributed computing
environments" consisting of multiple computing platforms, operating systems,
databases and networking protocols, and must implement off-the-shelf software
applications to support business objectives. Companies must also continually
keep pace with new developments, which often render existing equipment and
internal skills obsolete. At the same time, external economic factors have
forced organizations to focus on core competencies and trim workforces in the IT
management area. Accordingly, these organizations often lack the quantity or
variety of IT skills necessary to design and develop IT solutions. IT managers
are charged with developing and supporting increasingly complex IT systems and
applications of significant strategic value, while working under budgetary,
personnel and expertise constraints within their own organizations.
 
     According to IDC, the worldwide market for IT services was estimated at
$202 billion in 1996, with a projected market of $292 billion in 2000. IDC also
projects that the domestic IT services market will grow from $84 billion in 1996
to $130 billion in 2000. Currently, substantially all of the Company's revenues
from its IT Services Group are derived from IT staff augmentation services and
IT implementation and integration services, two segments within the overall IT
services industry. IDC estimates that the domestic market for IT implementation
and integration services was $22 billion in 1996, with a forecast of $35 billion
by 2000. According to the Staffing Industry Report, the domestic market for
technical/IT staff augmentation services was approximately $12 billion in 1996
and grew at a compounded annual rate of approximately 20% over the past five
years.
 
     Traditional Staffing Services. The staffing industry was once used
predominately as a short-term solution for peak production periods and to
temporarily replace workers absent due to illness, vacation, or abrupt
termination. Since the mid-1980s, the staffing services sector has evolved into
a permanent and significant component of the staffing plans of many
corporations. Corporate restructuring, downsizing, government regulations,
advances in technology, and the desire by many companies to shift employee costs
from a fixed to a variable expense have resulted in the use of a wide range of
staffing alternatives by businesses. In addition, the reluctance of corporations
to risk exposure to wrongful discharge claims has led to an increase in
companies using temporary staffing as a means of evaluating the qualifications
of personnel before hiring them on a full-time basis. Furthermore, many
companies are adopting strategies that focus on their core competencies and, as
a result, are outsourcing the support functions of their non-core competencies.
The National Association of Temporary and Staffing Services estimates that more
than 90% of all United States businesses use staffing services.
 
     According to the Staffing Industry Report, the U.S. staffing industry was
estimated to have 1996 revenues of approximately $47.1 billion and a compound
annual growth rate of approximately 17% over the past five years. Within the
staffing industry, the office/clerical/industrial sector was estimated to have
1996 revenues of approximately $26.4 billion and a compounded annual growth rate
of 17% over the past five years. The Company believes that the demand for
staffing services will continue to increase due to changes in workforce
lifestyles, advances in technology and the increasing desire of many companies
to shift employee costs from a fixed to a variable expense and to outsource the
support functions.
 
     The Company believes that the staffing industry is highly fragmented and is
continuing to experience increasing consolidation primarily due to the
increasing demand by large companies for centralized staffing services and the
difficulties faced by many smaller staffing companies in today's staffing
services market. The growth of national and regional accounts resulting from the
centralization of staffing decisions by national and larger regional companies
has increased the importance of staffing companies being able to offer a wide
range of services over a broad geographic area. In addition, many smaller
staffing companies are experiencing increased difficulties due to factors such
as significant working capital requirements, limited management resources, and
an increasingly competitive environment.

STRATEGY
 
     The Company seeks to expand on its success by broadening the range of IT
services and staffing services offered to its existing and prospective clients.
The Company's strategy is focused on internal growth, selective acquisitions,
and the continued development of additional complementary IT services and
staffing services. The Company believes that its business strategy will provide
it with a competitive advantage in pursuing and maintaining major national and
regional accounts as well as in serving local markets. The key elements of the
Company's strategy are presented below.
 
  Enhance Leadership Position in the Information Technology Services Sector
 
     In recent years, there has been a dramatic increase in demand for technical
project support, software development, and other IT services resulting from the
increased use of technology. This high level of demand, coupled with the high
value-added nature of such services, generally results in higher profit margins.
The Company has targeted the high-growth, high-margin IT services sector as its
primary growth area and intends to aggressively enhance its existing leadership
position in this sector.
 
     The Company established its IT Services Group with the acquisition of two
major businesses in September 1994 and June 1995. Since that time, the Company
has acquired 15 additional IT services businesses, including three IT solutions
businesses. As part of its strategy to offer a more complete range of high end,
value-added IT services to its clients, the Company formed its IT Solutions unit
in the first quarter of 1997. The Company believes that it is a leading provider
of IT staff augmentation services, with 1996 pro forma revenues of $374 million.
In 1996, pro forma revenues for the IT Services Group increased 32% over 1995,
reflecting internal growth, while increasing gross margins. The Company expects
that revenues contributed by this group will continue to increase as a
percentage of its total revenues.
 
     The Company believes that it is well positioned to capitalize on the
anticipated continued growth in the IT services sector due to its size,
geographic breadth, industry experience, and expertise in providing a wide range
of IT services. The Company intends to grow significantly in this area through
(i) selective acquisitions, (ii) aggressive recruiting, training, and marketing
of industry specialists with a wide range of technical expertise, (iii) opening
offices in new and existing markets, and (iv) active cross-selling of its IT
services to its existing IT and staffing services customers. The Company intends
to continue pursuing businesses with specializations in custom software
development, packaged software implementation, critical computer code
maintenance and network implementation and integration.
 
  Leverage Infrastructure and Existing Client Base for Internal Growth
 
     The Company has established a national branch network for its IT Services
Group and Staffing Services Group and has used this network to increase revenues
and enhance earnings stability. The Company believes that this geographic and
sector diversity helps to protect it from adverse regional economic and business
cycles. In addition, the Company's existing branch office network has the
infrastructure and support systems in place to enable it to expand and enhance
services while limiting additional expense. This allows the Company to achieve
significant economies through the allocation of management, advertising,
recruiting and training costs over a larger revenue base. Further economies of
scale are presented by the Company's three domestic and three international
development centers established to provide offsite software development services
for clients.
 
     The Company's branch office network, together with its software development
centers, provides it with an advantage when pursuing contracts with national
accounts. These accounts generally have numerous locations and a wide variety of
service needs. The Company's ability to meet the broad service requirements of
its clients provides a basis for establishing long-term relationships with
large-scale users of IT services and staffing services, and further provides the
Company with significant advantages over its competitors in marketing solutions
to such clients.

  Broaden Range of Value-added IT Services and Solutions
 
     The Company believes that it can increase its revenues from existing
clients and attract new clients by offering a broad range of IT services through
its IT Services Group. The IT Services Group is comprised of COMSYS, which
addresses IT staff augumentation requirements, and IT Solutions, which addresses
specific IT problems. In response to the rapidly changing nature of IT, the
Company regularly evaluates emerging technologies and their potential benefit as
new services to clients. Based on these evaluations, the Company may develop or
expand the service lines of existing business units or acquire complementary
businesses to enhance the Company's ability to support its clients' ongoing IT
requirements. IT Solutions is a recent addition to the service line that
provides value-added services, including Internet/Intranet services, Year 2000
solutions, new media solutions (such as multimedia-based Web site design),
software development, training services, critical code maintenance and software
testing and quality assurance.
 
  Expand Use of Offshore Development Centers
 
     In 1997, the Company acquired three offshore software development centers
in India which will provide the IT Services Group with a significant cost
advantage as well as the ability to provide 24-hour service to its clients. The
Company's costs in India are significantly lower than costs incurred for
comparable resources in the U.S. Through satellite communications, the Company's
clients may be directly linked to the IT Services Group's facilities in India.
Due to the time difference between India and the U.S., the Company can create a
virtual "second shift" for its North American clients allowing for more rapid
completion of projects and off-peak use of clients' technology resources. In
addition, for larger projects with critically short time frames, the offshore
facilities allow the Company to parallel process many of its development phases
to accelerate delivery time. The Company intends to continue to seek
opportunities to further use its facilities in India as well as evaluate other
offshore facilities that could provide similar cost advantages.
 
  Continue to Pursue Selective Acquisitions
 
     The Company has made 32 acquisitions since its inception in 1993. While the
Company initially concentrated its acquisition efforts on establishing a
national base of staffing services, the Company has more recently focused its
acquisition efforts in the higher-margin IT services sector. The Company is
currently focused on acquisitions to expand the services offered by COMSYS and
IT Solutions. Through June 30, 1997, the Company had acquired five businesses in
its IT Services Group with aggregate 1996 revenues of $49.0 million. Currently,
the Company has non-binding letters of intent to acquire three businesses, which
would complement its existing IT businesses. The following table shows
acquisition activity for each of the past three years and for the six months
ended June 30, 1997.

    1997, the aggregate contingent consideration due sellers based on increases
    in EBITDA is capped at $49.2 million.
 
     The Company is continually seeking acquisition opportunities and believes
there are a substantial number of attractive acquisition candidates in the
information technology and staffing services industries. The

<PAGE>   33
 
Company from time to time enters into discussions and non-binding letters of
intent that may lead to acquisitions but no assurances can be given that future
acquisitions will be consummated.
 
  Focus on Recruiting, Training and Retention
 
     The Company believes that its ability to attract and retain a broad
spectrum of high-quality employees, consultants and computer professionals is a
key element of its growth strategy. The Company has established a domestic and
international network to recruit employees, consultants and computer
professionals of all experience levels. The Company has 12 full-time employees
dedicated to recruiting in India as well as two full-time recruiters located in
the U.K. In the IT Services Group, the Company provides continual training
opportunities in software engineering techniques and key technologies. The
Company has made significant investments in its domestic and foreign training
centers, including centers that employ full-time instructors and are equipped
with client/server and mainframe hardware, software and development tools. These
training resources enhance the Company's ability to provide qualified IT
professionals to satisfy its client needs. In addition, the Company's
complementary services from staff augmentation to high-end software development
offer its IT professionals the opportunity to grow professionally within the
Company. The Company believes that this internal upward mobility is a critical
factor in continuing to attract and retain high-quality employees, consultants
and computer professionals.
 
  Entrepreneurial Corporate Environment
 
     The Company believes that its entrepreneurial business environment is an
important component of its strategy for growth. Each branch office is operated
as a separate profit center with local management having profit and loss
responsibilities. The Company believes that this management philosophy allows it
to attract and retain highly talented managers who have demonstrated the ability
to operate independently and succeed within a decentralized management
structure. The Company has established guidelines that offer its managers and
field personnel latitude in operational areas such as hiring, pricing, training,
sales, and marketing. In addition, the Company has a profit-based compensation
program at the national, regional and local levels and a broadly distributed
stock option program to further motivate employees through ownership in the
Company.
 
IT SERVICES GROUP
 
     The Company's strategic focus is to continue to grow the IT Services Group
through continued, aggressive acquisition and internal growth. Through June 30,
1997, the Company had acquired 17 IT services businesses, including three IT
solutions businesses.
 
  COMSYS
 
     COMSYS provides personnel to meet the growing need for employees with
advanced computer-related skills. As of June 30, 1997, COMSYS operated 45 branch
offices located in Alabama, Arizona, California, Colorado, Florida, Georgia,
Idaho, Illinois, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nevada,
New Jersey, New York, North Carolina, Ohio, Oklahoma, Oregon, Texas, Washington
and the United Kingdom.
 
     COMSYS offers staff for a full spectrum of computer-related services
ranging from traditional systems analysis to high value-added IT consulting and
project management. Depending upon the needs of the client, four primary types
of staffing services are offered: information and systems development services,
management services, advanced technology services, and government services.

highly-skilled information systems personnel ("software engineers") to meet
clients' specific needs in the following areas:
 
<TABLE>
<S>                       <C>

</TABLE>
 
     Management Services. As clients' technology needs have become more complex,
demand has increased for comprehensive IT solutions that involve not only staff
augmentation, but also management of the underlying project. In a management
services assignment, the Company assumes greater responsibility for a project's
success than it would in a traditional information services assignment. These
services are provided on the following bases:
 
<TABLE>
<S>                       <C>
Consulting Services --    development of solutions, usually delivered in a report or
                          recommendation, to a client's specific IT needs
Project Management        staffing and management of a specific IT project within
  and Project             written performance criteria and objectives including
  Outsourcing --          project outsourcing, both onsite and offsite
</TABLE>
 
     Advanced Technology Services. The Company provides leading-edge IT services
to staff positions that require knowledge of emerging technologies. Such
advanced technology services include IT architecture and engineering, systems
consulting, network systems consulting, complex internet enabled applications
and client/server and object oriented services. The Company supports all major
computer technology platforms (mainframe, mid-range, client server and network)
and supports client projects using a variety of software applications. The
Company implements SAP's client/server software, custom develops Oracle,
Informix, DB2, Visual Basic and C++ applications and implements and supports
Windows NT, Novell and UNIX based environments.
 
     Government Services. The Company provides software engineers and technical
consultants to 84 government agencies in 20 states and believes that it is a
major provider of IT services to state government agencies. In the government
services segment, the Company's personnel have technical expertise and
application knowledge primarily in health, welfare and human services,
transportation and highways, and environmental services.
 
     Year 2000 Services. The Company provides complete solutions to the Year
2000 computer programming problem. The Company's services involve assessing the
impact of the Year 2000 problem in information systems, planning solutions to
the Year 2000 problem, renovating program code, testing the changed programs and
rolling out the corrected applications.
 
     Technical Communications Outsourcing. COREComm maintains a full-time staff
of writers, editors, graphic artists, and consultants to fulfill the technical
communication outsourcing needs of its clients through four branch offices
located in Texas and Oklahoma. In an effort to further develop this business,
COREComm has established alliances with companies that have ongoing technical
communication needs, including company magazines, ISO 9000 documentation,
maintenance manuals, newsletters, on-line documentation, technical articles,
books, brochures, papers, reports, and product specification sheets.

  IT Solutions
 
     In March 1997, the IT Solutions unit was formed with the acquisition of
Metamor Technologies, Ltd. ("Metamor"), a Chicago-based firm. Since the
acquisition of Metamor, IT Solutions has acquired BMD, based in Irvine,
California and India, and Millennium Computer Corporation, based in Rochester,
New York.
 
     IT Solutions offers a full spectrum of IT services from the planning stage
through implementation of the final product or service. The IT Solutions unit
has the capability to perform the services desired by its clients onsite at the
customer's facility, offsite at one its of U.S. facilities or one of its
offshore Indian facilities. This provides its clients alternatives for achieving
their required business solutions, while at the same time providing IT Solutions
operating efficiencies that the Company believes gives it a competitive
advantage over its competitors.
 
     IT Solutions offers services that enable middle market and FORTUNE 1000
companies to use IT as a more effective business tool and supports these
companies' investment in IT. IT Solutions services include the following:
 
     Systems Integration -- IT Solutions provides custom application
development, package implementation and network integration, and specializes in
Oracle, Informix, DB2, Visual Basic and C++ applications, Windows NT, Novell and
Unix-based environments and Internet/Intranet solutions.
 
     Software Services -- IT Solutions focuses on developing software that
becomes part of their customers' products. This work includes development of
components of "shrink-wrap" packages, porting such products to different
platforms, and creating embedded software for various types of hardware
components.
 
     Legacy Application Support. IT Solutions provides mission critical 24-hour,
seven-day-a-week systems maintenance for legacy applications. These services are
provided through its three development centers located in India, using satellite
links that allow it to communicate with its customers' information systems.
Offsite support is primarily accomplished during the night time hours in the
U.S. when a customer's use of its information systems is limited. IT Solutions
also provides Year 2000 conversions through its India facilities. The Company
believes that many of its Year 2000 customers will become longer-term
maintenance customers.
 
     Software Development Centers. The Company maintains six software
development centers, of which three are located in India and three are located
in the United States in Portland, Oregon, Chicago, Illinois and Rochester, New
York. Through its development centers, the Company has the ability to perform a
portion or all of a client's IT requirements. IT Solutions performs the majority
of its turn-key projects, mainframe applications and additional services such as
custom software development, code maintenance and Web page development and
maintenance at its development centers. The ability to service the client's
needs offsite at one of the Company's development centers rather than onsite
provides the IT Solutions unit with greater operating efficiencies and quality
control. The Company's three offshore software development centers in India
provide the IT Services Group with a significant cost advantage as well as the
ability to provide 24-hour service to its clients. The Company's costs in India
are significantly lower than costs incurred for comparable resources in the U.S.
Through satellite communications, the Company's clients may be directly linked
to the IT Services Group's facilities in India. Due to the time difference
between India and the U.S., the Company can create a virtual "second shift" for
its North American clients allowing for more rapid completion of projects and
off-peak use of clients' technology resources. In addition, for larger projects
with critically short time frames, the offshore facilities allows the Company to
parallel process many of its development phases to accelerate delivery time. To
perform these services offshore the Company maintains over 65,000 square feet of
state of the art facilities in Hyderabad, Madras and New Delhi, India, and uses
six 64Kbps secured, high speed satellite links, NT computer servers, AS-400
mid-range computer servers, UNIX computer servers and S-390 development
machines.
 
STAFFING SERVICES GROUP
 
     CORESTAFF Services provides office/clerical, light industrial, and
electronic/technical services through 95 branch offices (including five
franchise offices) located in Alabama, Arizona, California, Colorado,
 
                                       32
<PAGE>   36
 
Connecticut, the District of Columbia, Florida, Georgia, Illinois, Maryland,
Nevada, New Jersey, New York, North Carolina, Pennsylvania, South Carolina,
Texas, Virginia and Wyoming. In Philadelphia and the New York City metropolitan
area, CORESTAFF Services operates under the name Leafstone Staffing Services.
CORESTAFF Services accounted for 50.6% and 53.8% of the Company's pro forma
revenues for the years ended December 31, 1996 and 1995, respectively.
Office/clerical staffing services include providing secretaries, word
processors, receptionists, general office support, telemarketers, data entry
personnel, bookkeepers, and collectors. Also included in the office/clerical
category are staffing services in the accounting, financial and library services
areas, all of which require specialized training. Light industrial staffing
includes the provision of unskilled and semi-skilled personnel in light
manufacturing and assembly, picking and packing, warehouse services, equipment
handling, inventory, and shipping and receiving. Electronic/technical staffing
includes the training and provision of skilled personnel in electronic
manufacturing.
 
     CORESTAFF Services provides a wide range of staffing options to its
clients, including, but not limited to, supplemental and project staffing and
Vendor-in-Partnership ("VIP") and Variable Capacity Strategies ("VCS") programs.
The appropriate staffing option depends on the nature and length of the
assignment and the degree of day-to-day management responsibility delegated to
the provider of the services.
 
     Supplemental Staffing. Often considered traditional or tactical temporary
help, supplemental staffing assignments generally range in duration from one day
to several months. Supplemental staffing provides clients with maximum
flexibility in meeting staffing requirements as clients may commence and
terminate assignments at any time and with short notice. In addition, because
clients generally only pay for the time actually worked by a supplemental
staffing employee, they can use supplemental staffing employees at any time and
on any day without paying a premium for shift, holiday, or weekend labor.
 
     Vendor-in-Partnership Programs. In response to increased client demand, the
Company provides, through its VIP program, coordination of temporary personnel
services by providing a dedicated onsite account manager to assist in the
procurement and management of the client's temporary workforce. Customized to
the needs of each client, the Company designs and implements programs that
include services such as specialized testing, drug screening, selection and
monitoring of back-up vendors, enforcement of the client's quality standards,
and orientation of each temporary employee to the client's work site, culture,
and job requirements. The Company had 47 VIP programs, which generated combined
pro forma revenues of approximately $103 million for the year ended December 31,
1996.
 
     Project Staffing. The Company provides contract employees to clients who
require personnel to staff specific projects for a defined period of time.
Generally, project staffing involves a commitment of a team of employees who
remain at the site until completion of the project.
 
     Variable Capacity Strategies ("VCS"). VCS is a staffing service program
that improves productivity and total quality output by reducing turnover through
proactive training and rotation of employees performing repetitive job
assignments. VCS, which was added to the Company's service offerings in 1996 as
a result of the acquisition of Transworld Services Group, generates
significantly higher margins than most of the Company's other staffing services
offerings. Currently, this program is being used by only a few of the Company's
customers and the Company is developing a roll-out strategy and methodology to
extend this program throughout the U.S.
 
     Specialized Software Tools. During 1996, CORESTAFF Services added a number
of software tools, including COREtrack and COREskills, in an effort to give the
Company a competitive marketing advantage. COREtrack is a specialized software
program that assists clients in managing critical information related to
multiple staffing providers. This system tracks a wide-range of information,
including orders, activity assignments and invoices. COREskills is an
interactive computer training and certification program that trains and
qualifies temporary and client employees in the latest office software products.

INTEGRATION OF ACQUIRED COMPANIES
 
     Management begins integrating newly acquired companies as soon as
practicable. This process involves formalizing and standardizing each acquired
company's marketing and sales programs and field operations procedures.
Standardized personnel manuals are distributed, and the acquired company is
brought under the Company's uniform risk management program. In some cases, the
Company closes certain of the acquired company's offices and merges its
operations and personnel, including field employees, into the Company's existing
business.
 
     The Company is in the process of installing an integrated front- and
back-office information system. Once operational, the Company will convert all
its front- and back-office activities onto this new platform. This new system
will integrate the Company's two proprietary front-office systems with the
"PeopleSoft" system, which is a payroll, human resources, accounting and
reporting information system. The Company's front-office systems are MARS, a
proprietary management, administrative, recruiting and sales software system,
designed specifically for COMSYS, and COREmatch, a proprietary staffing services
front-office software system. Once implemented, this integrated information
system will improve the timeliness and efficiency of data gathering and
retrieval.
 
BRANCH OFFICES AND CENTRALIZED BUSINESS OPERATIONS
 
     The Company provides staffing, contracting and outsourcing services through
147 company-operated branch offices and five franchise-operated branch offices
located in 28 states, the District of Columbia, the United Kingdom and India.
The IT Services Group and the Staffing Services Group maintain separate
facilities. All of the Company's branch offices are leased and the average lease
term is three to five years. As of June 30, 1997, the Company had 45 IT services
branch offices, 95 staffing services branch offices and seven IT Solutions
offices.
 
SALES AND MARKETING
 
     COMSYS and CORESTAFF Services have each developed a sales and marketing
strategy that focuses on national, regional and local accounts and is
implemented through their branch locations. Regional and local accounts are
targeted by account managers at the branch offices, permitting the Company to
capitalize on the local expertise and established relationships of its branch
office employees. Such accounts are solicited through personal sales
presentations, telephone marketing, direct mail solicitation, referrals from
clients, and advertising in a variety of local and national media, including the
Yellow Pages, newspapers, and trade publications. The Company also conducts
public relations activities designed to enhance public recognition of the
Company and its services. Local employees are encouraged to be active in civic
organizations and industry trade groups to facilitate the development of new
customer relationships.
 
     The Company's national sales and marketing effort is coordinated by
management at the corporate level, which enables the Company to develop a
consistent, focused strategy to pursue national account opportunities. This
strategy allows the Company to capitalize on the desire of national clients to
work with a limited number of preferred vendors for their staffing requirements.
 
     The IT Solutions unit generates sales by focusing either on specific
industries or functional areas of expertise. IT Solutions also capitalizes on
established relationships between the Company and targeted prospects and has a
dedicated sales force focused on generating new customers and relationships. The
Company intends to establish a global sales organization for the IT Solutions
unit.
 
RECRUITING AND RETENTION
 
     In the IT services sector, the demand for software engineers and technology
consultants significantly exceeds supply. The IT Services Group's success
depends in large part on its ability to attract, develop, motivate and retain
highly skilled IT professionals. The Company recruits from a number of
countries, including India, the U.S., Canada, the U.K., Singapore, Australia,
South Africa and the Philippines. The
 
                                       35
<PAGE>   39
 
Company advertises in leading newspapers and trade magazines. The Company uses a
standardized global selection process which includes interviews, tests and
reference checks.
 
     CORESTAFF Services recruits its temporary and contract employees through a
recruiting program that primarily uses local and national advertisements and job
fairs. In addition, CORESTAFF Services has succeeded in recruiting qualified
employees through referrals from its existing labor force. As a result, the
Company has initiated a policy whereby it pays referral fees to employees
responsible for attracting new recruits. The Company believes this balanced
recruiting strategy will continue to provide it with sufficient high quality
temporary employees to meet its staffing demands.
 
     In an effort to attract a wide spectrum of employees, the IT Services Group
offers diverse employment options and training programs. The two primary
approaches the IT Services Group uses are full-time employee status with an
annual salary irrespective of assignment, and hourly contingent worker status
for which compensation is tied to the duration of the assignment.
 
ASSESSMENT AND TRAINING
 
     To better meet the needs and requirements of its clients and to enhance the
marketability and job satisfaction of its employees, the Company uses a
comprehensive system to assess and train its employees. The Company conducts
extensive background, drug, and skills screening of potential temporary
employees and contract consultants and provides these employees with written and
video workplace orientation courses that are tailored to the practices and
policies of specific clients. Computerized tutorials are available in the
CORESTAFF Services branch offices for temporary employees wishing to upgrade
their typing, data entry, spreadsheet, office automation, desktop publishing, or
word processing skills. In addition, the IT Services Group maintains 13 domestic
and foreign learning centers covering a broad spectrum of courses concerning
mainframe applications development and maintenance, client/server technology,
and desktop-user support. These learning centers are located in Austin and
Dallas, Texas; Cleveland, Ohio; Raleigh, North Carolina; St. Louis, Missouri;
Chicago and Springfield, Illinois; Tallahassee, Florida; Atlanta, Georgia;
Rockville, Maryland, Rochester, New York and Hyderabad, India.
 
COMPETITION
 
     The market for IT solutions services includes a large number of
competitors, is subject to rapid change and is highly competitive. Primary
competitors in the IT solutions services market include participants from a
variety of market segments, including "Big Six" accounting firms, systems
consulting and implementation firms, application software firms, service groups
of computer equipment companies, facilities management companies, general
management consulting firms and programming companies. Many of the Company's
competitors have significantly greater financial, technical and marketing
resources and greater name recognition than the Company. In addition, the
Company competes with its clients' internal resources, particularly where these
resources represent a fixed cost to the client. Such competition may impose
additional pricing pressures on the Company.
 
     The staffing services industry is fragmented and highly competitive, with
limited barriers to entry. Within local markets, smaller firms actively compete
with the Company for business, and in most of these markets, no single company
has a dominant share of the market. The Company also competes with larger
full-service and specialized competitors that have significantly greater
marketing, financial and other resources than the Company. The Company believes
that the primary competitive factors in obtaining and retaining clients are the
ability to provide a wide range of staffing services within an expansive
geographic area, to understand the client's specific job requirements, to
provide temporary personnel with the appropriate skills in a timely manner, to
monitor quality of job performance, and to properly price services. The primary
competitive factors in obtaining qualified candidates for temporary employment
assignments are wages, responsiveness to work schedules, and the number of hours
of work available. Management believes that the Company is highly competitive in
these areas.

WORKERS' COMPENSATION PROGRAM; SAFETY PROGRAM
 
     The Company maintains workers' compensation insurance for all claims in
excess of a deductible of $250,000 per occurrence and an aggregate $5 million
limit of liability provision per year through May 31, 1997, increased to $10
million per year beginning June 1, 1997. The Company's insurance carrier
currently requires the Company to maintain irrevocable letters of credit to
cover potential losses related to the self-insurance portion of its program.
Under its workers' compensation program, field personnel work in conjunction
with a designated risk manager and a third-party administrator to manage claims
and establish appropriate reserves for the deductible portion of claims. An
independent actuary provides advice on overall workers' compensation costs as
well as an actuarial valuation regarding the adequacy of the reserves for
payments relating to the uninsured portion of workers' compensation claims. The
reserve balances determined by the third-party administrator and Company
management are adjusted to the amounts recommended by the actuary.
 
     The Company has a safety program in its branch offices to provide
appropriate safety training to employees prior to job assignment. The risk
manager and field personnel also perform safety inspections at customer
locations to help determine potential risks for employee injury and to assist
customers in making the workplace safer. Company policies prohibit staffing of
high-risk work. Behavioral testing is also used to help reduce unnecessary
claims.
 
EMPLOYEES
 
     At December 31, 1996, the Company employed approximately 2,000 full-time
staff employees and had approximately 3,800 IT consultants on assignment. During
1996, the Company employed approximately 91,000 temporary and contract employees
and had an average of approximately 23,000 employees on assignment per week. As
of December 31, 1996, approximately 11% of the Company's IT professionals were
citizens of other countries, with most of those in the U.S. working under H-1B
temporary work permits. The Company is not a party to any collective bargaining
agreements and considers its relationships with its employees to be
satisfactory.
 
     The Company is responsible for and pays the employer's share of Social
Security taxes (FICA), federal and state unemployment taxes, workers'
compensation insurance, and other costs relating to its temporary employees. The
Company makes health insurance benefits available to its temporary employees.
Generally, temporary employees with more than 1,000 hours of service per year
are eligible to participate in the Company's 401(k) Retirement Savings Plan.

                          DESCRIPTION OF CAPITAL STOCK
 
     Pursuant to the Certificate of Incorporation, the Company's authorized
capital stock consists of 100,000,000 shares of Common Stock; 3,000,000 shares
of Non-Voting Common Stock; and 5,000,000 shares of Preferred Stock. As of July
15, 1997, the Company had 32,081,745 shares of Common Stock issued and
31,397,745 shares outstanding; 707,232 shares of Non-Voting Common Stock issued
and outstanding; and no shares of Preferred Stock issued or outstanding.
 
COMMON STOCK
 
     Holders of Common Stock are entitled to one vote per share in the election
of directors and on all other matters submitted to a vote of stockholders and do
not have cumulative voting rights. Subject to preferences that may be applicable
to any outstanding Preferred Stock, the holders of Common Stock are entitled to
receive ratably such dividends, if any, as may be declared from time to time by
the Board of Directors out of funds legally available therefor. See "Dividend
Policy." In the event of liquidation, dissolution or winding up of the Company,
the holders of Common Stock are entitled to receive, after payment of the
Company's debts and liabilities, the remaining assets of the company on a
ratable basis. This right, however, is subject to (i) any prior liquidation
rights of Preferred Stock then outstanding (to the extent such rights are
designated by the Board of Directors) and (ii) any rights of holders of
Preferred Stock to share ratably with holders of Common Stock in all assets
remaining after payment of liabilities and liquidation preferences (to the
extent such rights are designated by the Board of Directors). The Common Stock
has no preemptive or conversion rights or other subscription rights. There are
no redemption or sinking fund provisions applicable to the Common Stock. All
shares of Common Stock currently outstanding are fully paid and non-assessable.
 
NON-VOTING COMMON STOCK
 
     Except as required by applicable law, the holders of Non-Voting Common
Stock are not entitled to vote in the election of directors or on any other
matters submitted to a vote of stockholders. In addition, Non-Voting Common
Stock (i) may only be issued to and held by a "Regulated Stockholder" which is
defined in the Certificate of Incorporation to be an entity subject to the
Federal Reserve Board's rules and regulations, (ii) may be converted into Common
Stock at any time at the option of the holder thereof on a one-for-one basis;
provided, however, any such conversion may only be made if in the opinion of the
holder of the Non-Voting Common Stock the regulations of the Federal Reserve
Board in effect at such time would not prohibit a national bank holding company
from holding such shares of Common Stock, and (iii) is subject to the same
dividend and liquidation preferences and benefits as the Common Stock. Except
for the restrictions on ownership, voting, and conversion, the Non-Voting Common
Stock is substantially similar to the Common Stock.
 
PREFERRED STOCK
 
     The Board of Directors has the authority to issue up to 5,000,000 shares of
Preferred Stock in one or more series and to fix the rights, preferences,
privileges and restrictions granted to or imposed upon any unissued shares of
Preferred Stock and to fix the number of shares constituting any series and the
designations of such series, without any further vote or action by the
stockholders. Although it currently has no intention to do so, the Board of
Directors, without stockholder approval, can issue Preferred Stock with voting
and conversion rights which could adversely affect the voting power of the
holders of Common Stock. The issuance of Preferred Stock may have the effect of
delaying, deferring or preventing a change in control of the Company.
 
PROVISIONS HAVING POSSIBLE ANTI-TAKEOVER EFFECTS
 
     The Certificate of Incorporation and the Bylaws of the Company contain
provisions that could have an anti-takeover effect. These provisions are
intended to enhance the likelihood of continuity and stability in the
composition of the Board of Directors of the Company and in the policies
formulated by the Board of Directors and to discourage certain types of
transactions which may involve an actual or threatened change of control of the
Company. The provisions are designed to reduce the vulnerability of the Company
to an
 
                                       42
<PAGE>   46
 
unsolicited proposal for a takeover of the Company that does not contemplate the
acquisition of all of its outstanding shares or an unsolicited proposal for the
restructuring or sale of all or part of the Company. The provisions are also
intended to discourage certain tactics that may be used in proxy contests. Set
forth below is a description of such provisions in the Certificate of
Incorporation and the Bylaws. The Board of Directors has no current plans to
formulate or effect additional measures that could have an anti-takeover effect.
 
     Pursuant to the Certificate of Incorporation, directors, other than those,
if any, elected by the holders of Preferred Stock, can be removed from office by
the affirmative vote of the holders of 66 2/3% of the voting power of the then
outstanding shares of capital stock entitled to vote thereon ("Voting Stock").
Vacancies on the Board of Directors may be filled by the remaining directors and
does not require stockholder approval.
 
     The Certificate of Incorporation of the Company provides for the Board of
Directors to be divided into three classes, with staggered three-year terms. As
a result, only one class of directors will be elected at each annual meeting of
stockholders of the Company, with the other classes continuing for the remainder
of their respective three-year term. The classification of the Board of
Directors makes it more difficult to replace the Board of Directors as well as
for another party to obtain control of the Company by replacing the Board of
Directors. Since the Board of Directors has the power to retain and discharge
officers of the Company, these provisions could also make it more difficult for
existing stockholders or another party to effect a change in management.
 
     The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law (the "DGCL"). In general, Section 203 prohibits a
publicly-held Delaware corporation from engaging in a "business transaction"
with an "interested stockholder" for a period of three years after the date that
the person became an interested stockholder unless (with certain exceptions) the
business combination or the transaction in which the person became an interested
stockholder is approved in a prescribed manner. A "business combination"
generally includes, without limitation, a merger, assets or stock sale, or a
transaction resulting in a financial benefit to the interested stockholder. An
"interested stockholder" generally is a person who, together with affiliates and
associates, owns (or within three years prior, did own) 15% or more of the
corporation's outstanding voting stock.
 
     In addition, the Company's Certificate of Incorporation provides that in
addition to any other vote required by law, the following actions involving the
Company or its subsidiaries and an interested stockholder (an "interested
stockholder" is defined in the Certificate of Incorporation to generally include
any person, entity or group which beneficially owns 10% or more of the
outstanding Voting Stock of the Company) shall require the affirmative vote of
both the holders of shares constituting 66 2/3% of the Voting Stock of the
Company and the holders of the majority of the shares of Common Stock at the
time outstanding, given in person or by proxy at a meeting called for such
purpose at which the holders of Common Stock shall vote separately as a class
(a) for any merger, consolidation or reorganization, (b) for any sale, lease,
exchange, mortgage, pledge, transfer or other disposition of (1) the Company's
or its subsidiaries' assets to an interested stockholder or (2) an interested
stockholder's assets to the Company or its subsidiaries, (c) for any issuance,
sale, exchange, disposition or other transfer or any reclassification or
recapitalization of any securities of the Company or its subsidiaries with a
value of $1.0 million or more, and (d) for certain other material corporate
transactions with an interested stockholder; provided, however, in the event
neither (y) more than 66 2/3% of the Company's directors shall have expressly
approved the transaction or (z) the stockholders receive a fair price for their
holdings and other requirements are fulfilled as set forth in the Certificate of
Incorporation, such special vote of the stockholders shall not be required. A
"fair price" shall be deemed to be an amount equal to the highest amount of
consideration paid by the interested stockholder for a share of Common Stock of
Non-Voting Common Stock (collectively, "Common Equity") at any time within a two
year period immediately prior to the date such interested stockholder became an
interested stockholder and during any time while such interested stockholder was
an interested stockholder.
 
     The Certificate of Incorporation provides that except as otherwise provided
for with respect to the rights of holders of Preferred Stock, no action that is
required or permitted to be taken by the stockholders of the Company at any
annual or special meeting of the stockholders may be effected by written consent
of the stockholders in lieu of a meeting of stockholders, unless the actions to
be effected by written consent of the
 
                                       43
<PAGE>   47
 
stockholders and the taking of such action by such written consent has been
expressly approved in advance by the Board of Directors of the Company. This
provisions makes it difficult for stockholders to initiate or effect an action
by written consent, and thereby effect an action opposed by the Board of
Directors. The Certificate of Incorporation and Bylaws also provide that special
meetings of stockholders may be called only by the Chairman of the Board, the
Vice Chairman of the Board, the Chief Executive Officer, or the President of the
Company, the Board of Directors of the Company, or the holders of at least 25%
of the outstanding Voting Stock. In addition, the Bylaws set forth an advance
notice procedure with regard to business to be brought before an annual meeting
of stockholders of the Company.
 
     The Certificate of Incorporation further provides that the Board of
Directors, by a majority vote, may adopt, alter, amend or repeal provisions of
the Bylaws. However, stockholders may only adopt, alter, amend or repeal
provisions of the Bylaws by a vote of 66 2/3% or more of the combined voting
power of the then outstanding Voting Stock. In addition, the Certificate of
Incorporation provides that whenever any vote of Voting Stock is required by law
to amend, alter, repeal or rescind ("Change") any provision thereof, then, in
addition to any affirmative vote required by law (i) the affirmative vote of
66 2/3% or more of the combined voting power of the then outstanding shares of
Voting Stock is required to Change certain provisions of the Certificate of
Incorporation, including the provisions referred to above relating to interested
stockholder transactions, the filling of vacancies on the Board of Directors,
the removal of directors, the limitations on stockholder action by written
consent, the calling of special meetings by stockholders and the approval of
amendments to the Company's Bylaws and (ii) if at such time there exists one or
more interested stockholders, such Change must also be approved by the
affirmative vote of the holders of at least a majority of the combined voting
power of the outstanding shares of Voting Stock beneficially owned by persons
other than the interested stockholder or any affiliate or associate thereof.
 
LIMITATION ON DIRECTORS' AND OFFICERS' LIABILITY; INDEMNIFICATION
 
     The Certificate of Incorporation of the Company limits the liability of the
directors of the Company to the Company or its stockholders (in their capacity
as directors but not in their capacity as officers) to the fullest extent
permitted by the DGCL. Accordingly, pursuant to the terms of the DGCL as
presently in effect, directors of the Company will not be personally liable for
monetary damages for breach of a director's fiduciary duty as a director, except
for liability (i) for any breach of the director's duty of loyalty to the
Company or its stockholders, (ii) for acts and omissions not in good faith or
which involve international misconduct or a knowing violation of law, (iii) for
unlawful payments of dividends or unlawful stock repurchases or redemptions as
provided in Section 174 of the DGCL, or (iv) for any transaction from which the
director derived an improper personal benefit. In addition, such provisions do
not limit the rights of the Company or its stockholders, in appropriate
circumstances, to seek equitable remedies such as injunctive or other forms of
non-monetary relief. Such remedies may not be effective in all cases. The
Certificate of Incorporation also provides that if the DGCL is amended after the
approval of the Certificate of Incorporation to authorize corporate action
further eliminating or limiting the personal liability of the directors, then
the liability of a director of the Company will be eliminated or limited to the
full extent permitted by the DGCL, as so amended. In addition, the Certificate
of Incorporation provides that the Company may purchase and maintain insurance
on behalf of any director, officer, employee or agent of the Company who is or
was serving, at the request of the Corporation, as director, officer, employer,
or agent for another corporation, partnership, joint venture, trust or other
enterprise against any liability asserted against him and incurred by him in
such capacity or arising out of his status as such, whether or not the Company
would have the power to indemnify such person for such liability under the DGCL.
 
     In addition, the Bylaws, in substance, require the Company to indemnify
each person who is or was, a director, officer, employee or agent of the Company
to the full extent permitted by the laws of the State of Delaware in the event
he/she is involved in legal proceedings by reason of the fact that he/she is or
was a director, officer, employee or agent of the Company, or is or was serving
at the Company's request as a director, officer, employee or agent of another
corporation, partnership or other enterprise. The Company is also required to
advance to such persons payments incurred in defending a proceeding to which
indemnification might apply, provided the recipient provides an undertaking
agreeing to repay all such advanced amounts
 
                                       44
<PAGE>   48
 
if it is ultimately determined that he is not entitled to be indemnified. In
addition, the Bylaws specifically provide that the indemnification rights
granted thereunder are non-exclusive.
 
INDEMNIFICATION AGREEMENTS
 
     Each director of the Company has also entered into an indemnification
agreement with the Company (the "Indemnification Agreements"). The
Indemnification Agreements are intended to permit indemnification which may be
broader than specifically provided by law. It is possible that the applicable
law could change the degree to which indemnification is expressly permitted.
 
     The Indemnification Agreements cover most monetary liabilities paid in
settlement or defense of claims if the indemnified party acted in good faith and
in the manner he or she believed to be in or not opposed to the best interests
of the Company or, with respect to a criminal proceeding, had no reason to
believe his or her conduct was unlawful. The determination as to whether such
standard of conduct has been met is determined by a majority of disinterested
directors of if there are no such directors, by independent legal counsel of the
stockholders. The Indemnification Agreements cover claims relating to the fact
that the indemnified party is or was a director, officer, employee, or agent of
the Company or its subsidiary, or is or was serving at the request of the
Company as a director, officer, employee, or agent for another entity. The
Indemnification Agreements also obligate the Company to promptly advance all
expenses incurred in connection with any claim. The indemnitee is, in turn,
obligated to reimburse the Company for all amounts so advanced if it is later
determined that the indemnitee is not entitled to indemnification. The
indemnification provided under the Indemnification Agreements is not exclusive
of any other indemnity rights.
 
TRANSFER AGENT AND REGISTRAR
 
     The Transfer Agent and Registrar for the Common Stock is American Stock
Transfer & Trust Company.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of the Stock Offerings, the Company will have outstanding
31,397,745 shares of Common Stock and 207,232 shares of Non-Voting Common Stock
(assuming no exercise of outstanding options or conversion of the Notes). Of
such shares 12,158,982 shares of Common Stock and 207,232 shares of Non-Voting
Common Stock are considered "restricted securities" for the purpose of Rule 144
under the Securities Act and may only be sold if they are registered under the
Securities Act or if an exemption from registration is available, including an
exemption afforded by Rule 144 under the Securities Act. Upon the expiration of
certain lockup agreements, most of the restricted securities will be eligible
for sale in the public market under Rule 144 or Rule 701 of the Securities Act
as described below.
 
     In general, under Rule 144, as currently in effect, a person (or persons
whose shares are aggregated), including an affiliate of the Company, who has
beneficially owned his or her restricted securities for at least one year but
less than two years, is entitled to sell within any three-month period a number
of such shares that does not exceed the greater of (i) 1% of the then
outstanding shares of Common Stock or (ii) the average weekly trading volume in
the Common Stock during the four calendar weeks preceding the date on which
notice of such sale is filed with the Securities and Exchange Commission (the
"Commission"). Sales pursuant to Rule 144 are subject to certain requirements
relating to manner of sale, notice, and availability of current public
information about the Company. A person who is not deemed to have been an
affiliate of the Company at any time during the three months preceding a sale,
and who owns shares that have not been held by the Company or an affiliate of
the Company for at least two years, would be entitled to sell the shares under
Rule 144(k) without compliance with the limitations described above. Restricted
securities properly sold in reliance on Rule 144 are thereafter freely tradeable
without restrictions or registration under the Securities Act unless thereafter
held by an affiliate of the Company.
 
     In general, under Rule 701 under the Securities Act, any employee, officer,
or director of or consultant to the Company who purchased his or her shares
pursuant to a written compensatory plan or contract is entitled to rely on the
resale provisions of Rule 701. Such provisions permit nonaffiliates to sell
their Rule 701 shares
 
                                       45
<PAGE>   49
 
without having to comply with the public information, holding period, volume
limitation, or notice provisions of Rule 144 and permit affiliates to sell their
Rule 701 shares without having to comply with the Rule 144 holding period
restrictions.
 
     The Company has reserved an aggregate of 3,840,000 shares of Common Stock
for issuance pursuant to the 1995 Plan. The Company has filed a registration
statement under the Securities Act with respect to the shares reserved for
issuance under the 1995 Plan. The Company has reserved an aggregate of 450,000
shares of Common Stock for issuance pursuant to the Stock Purchase Plan. The
Company has filed a registration statement under the Securities Act with respect
to the shares reserved for issuance under the Stock Purchase Plan. In addition,
the Company has reserved        shares of Common Stock for issuance upon
conversion of the Notes.
 
     Sales of substantial amounts of Common Stock in the public market could
adversely affect the market price of the Common Stock and could impair the
Company's future ability to raise capital through the sale of its equity
securities.
 
REGISTRATION RIGHTS
 
     GTC III, First Union, Michael T. Willis, the Leslie J. Cohen Trust, William
L. Caudell, Daniel L. Shimer, Peter T. Dameris, Rocco N. Aceto, Joseph V.
Amella, John T. Turner and Charles R. Schneider are parties to a Registration
Agreement with the Company (the "Registration Agreement") under which each has
certain rights with respect to the registration under the Securities Act, for
resale to the public, of an aggregate of 12,866,214 shares of Common Stock and
Non-Voting Common Stock (the "Registrable Shares") after giving effect to the
completion of the Stock Offerings (          shares if the Underwriters'
over-allotment option is exercised in full). The Registration Agreement provides
that in the event the Company proposes to register any of its securities under
the Securities Act and the registration form to be used to register such
securities may also be used for the registration of the Registrable Shares, such
stockholders will be entitled to include Registrable Shares in such
registration, subject to certain conditions and limitations, including the right
of the managing underwriter of any such offering to exclude for marketing
reasons all or some of the Registrable Shares from such registration. In
addition, GTC III and First Union each have the right, subject to certain
conditions and limitations, to require the Company to register such Registrable
Shares on a Form S-1 on no more than three occasions or on a Form S-2 or S-3 or
any other similar short-form registration, if available, on an unlimited number
of occasions. The Company will be obligated to pay all expenses associated with
the exercise of such registration rights other than underwriting discounts or
commissions incurred in connection with such registration.

     The U.S. Underwriters and the International Underwriters and the U.S.
Representatives and the International Representatives are collectively referred
to as the "Underwriters" and the "Representatives," respectively. The Common
Stock Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of Common Stock
offered hereby are subject to the approval of certain legal matters by their
counsel and to certain other conditions. The Underwriters are obligated to take
and pay for all of the shares of Common Stock offered hereby (other than those
covered by the U.S. Underwriters' over-allotment described below) if any such
shares are taken.
 
     Pursuant to the Agreement between U.S. and International Underwriters, each
U.S. Underwriter has represented and agreed that, with certain exceptions, (i)
it is not purchasing any Shares for the account of anyone other than a United
States or Canadian Person (as defined herein) and (ii) it has not offered or
sold, and will not offer or sell, directly or indirectly, any Shares or
distribute any prospectus relating to the Shares outside the United States or
Canada or to anyone other than a United States or Canadian Person. Pursuant to
the Agreement between U.S. and International Underwriters, each International
Underwriter has represented and agreed that, with certain exceptions, (i) it is
not purchasing any Shares for the account of any United States or Canadian
person and (ii) it has not offered or sold, and will not offer or sell, directly
or indirectly, any Shares or distribute any prospectus relating to the Shares in
the United States or Canada or to any United States or Canadian person. With
respect to any Underwriter that is a U.S. Underwriter and an International
Underwriter, the foregoing representations and agreements (i) made by it in its
capacity as a U.S. Underwriter apply only to it in its capacity as a U.S.
Underwriter and (ii) made by it in its capacity as an
 
                                       47
<PAGE>   51
 
International Underwriter apply only to it in its capacity as an International
Underwriter. The foregoing limitations do not apply to stabilization
transactions or to certain other transactions specified in the Agreement between
U.S. and International Underwriters. As used herein "United States or Canadian
person" means any national or resident of the United States or Canada, or any
corporation, pension, profit-sharing or other trust or other entity organized
under the laws of the United States or Canada or of any political subdivision
thereof (other than a branch located outside the United States and Canada of any
United States or Canadian Person), and includes any United States or Canadian
branch of a person who is otherwise not a United States or Canadian person. All
shares of Common Stock to be purchased by the Underwriters are referred to
herein as the "Shares."
 
     Pursuant to the Agreement between U.S. and International Underwriters,
sales may be made between the U.S. Underwriters and International Underwriters
of any number of Shares as may be mutually agreed. The per share price of any
Shares so sold shall be the public offering price set forth on the cover page
hereof, in United States dollars, less an amount not greater than the per share
amount of the concession to dealers set forth below.
 
     Pursuant to the Agreement between U.S. and International Underwriters, each
U.S. underwriter has represented that it has not offered or sold, and has agreed
not to offer or sell, any Shares, directly or indirectly, in any province or
territory of Canada in contravention of the securities laws thereof and has
represented that any offer of Shares in Canada will be made only pursuant to an
exemption from the requirement to file a prospectus in the province or territory
of Canada in which such offer or sale is made. Each U.S. Underwriter has further
agreed to send to any dealer who purchases from it any of the Shares a notice
stating in substance that, by purchasing such Shares, such dealer represents and
agrees that it has not offered or sold, and will not offer or sell, directly or
indirectly, any of such Shares in any province or territory of Canada or to, or
for the benefit of, any resident of any province or territory of Canada in
contravention of the securities laws thereof and that any offer of Shares in
Canada will be made only pursuant to an exemption from the requirement to file a
prospectus in the province or territory of Canada in which such offer or sale is
made, and that such dealer will deliver to any other dealer to whom it sells any
of such Shares a notice containing substantially the same statement as is
contained in this sentence.
 
     Pursuant to the Agreement between U.S. and International Underwriters, each
International Underwriter has represented and agreed that (i) it has not offered
or sold and, prior to the date six months after the closing date for the sale of
the Shares to the International Underwriters, will not offer or sell, any Shares
to persons in the United Kingdom except to persons whose ordinary activities
involve them in acquiring, holding, managing or disposing of investments (as
principal or agent) for the purposes of their businesses or otherwise in
circumstances which have not resulted and will not result in an offer to the
public in the United Kingdom within the meaning of the Public Offers of
Securities Regulations 1995; (ii) it has complied and will comply with all
applicable provisions of the Financial Services Act 1986 with respect to
anything done by it in relation to the Shares in, from or otherwise involving
the United Kingdom; and (iii) it has only issued or passed on and will only
issue or pass on in the United Kingdom any document received by it in connection
with the offering of the Shares to a person who is of a kind described in
Article 11(3) of the Financial Services Act 1986 (Investment Advertisements)
(Exemptions) Order 1996 or is a person to whom such document may otherwise be
lawfully issued or passed on.
 
     The Underwriters initially propose to offer part of the Shares directly to
the public at the public offering price set forth on the cover page hereof and
part to certain dealers at a price which represents a concession not in excess
of $          per share under the public offering price. An Underwriter may
allow, and such dealers may reallow, a concession not in excess of $
per share to other Underwriters or to certain other dealers. After the initial
offering of the Shares, the offering price and other selling terms may from time
to time be varied by the Representatives.
 
     Michael T. Willis has granted to the U.S. Underwriters an option,
exercisable for 30 days from the date of this Prospectus, to purchase up to an
aggregate of 900,000 additional Shares at the public offering price set forth on
the cover page hereof, less underwriting discounts and commissions. The U.S.
Underwriters may exercise such option solely for the purpose of covering
over-allotments, if any, made in connection with the
 
                                       48
<PAGE>   52
 
offering of the Shares offered hereby. To the extent such option is exercised,
each U.S. Underwriter will become obligated, subject to certain conditions, to
purchase approximately the same percentage of such additional Shares as the
number set forth next to such U.S. Underwriter's name in the preceding table
bears to the total number of Shares set forth next to the names of all U.S.
Underwriters in the preceding table.
 
     Each of the Company and the directors and executive officers of the Company
and the Selling Stockholders has agreed that, without the prior written consent
of Morgan Stanley & Co. Incorporated on behalf of the Underwriters, it will not,
during the period ending 90 days (45 days in the case of the directors and
executive officers) after the date of this Prospectus, (i) offer, sell, contract
to sell, sell any option or contract to purchase, purchase any option or
contract to sell, grant any option, right or warrant to purchase, loan or
otherwise dispose of, directly or indirectly, any shares of Common Stock or any
securities convertible into or exercisable or exchangeable for Common Stock, or
(ii) enter into any swap or other arrangement that transfers to another, in
whole or in part, any of the economic consequences of ownership of the Common
Stock, whether any such transaction described in clause (i) or (ii) above is
settled by delivery of Common Stock or such other securities, in cash or
otherwise. Each of the Selling Stockholders has also agreed that, without the
prior written consent of Morgan Stanley & Co. Incorporated on behalf of the
Underwriters, it will not, during the period ending 90 days after the date of
this Prospectus, make any demand for, or exercise any right with respect to, the
registration of any shares of Common Stock. The restriction on the Company is
subject to exceptions for the issuance of Common Stock pursuant to existing
director and employee benefit plans and as payment for acquisitions by the
Company. The restriction on the officers, directors and Selling Stockholders is
subject to exceptions for charitable contributions and estate planning so long
as the recipient or donee is subject to a similar restricted transfer period.
 
     In order to facilitate the offering of the Common Stock, the Underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the Common Stock. Specifically, the Underwriters may over-allot in
connection with the offering, creating a short position in the Common Stock for
their own account. In addition, to cover overallotments or to stabilize the
price of the Common Stock, the Underwriters may bid for, and purchase, shares of
the Common Stock in the open market. Finally, the underwriting syndicate may
reclaim selling concessions allowed to an Underwriter or a dealer for
distributing the Common Stock in the offering if the syndicate repurchases
previously distributed Common Stock in transactions to cover syndicate short
positions, in stabilization transactions or otherwise. Any of these activities
may stabilize or maintain the market price of the Common stock above independent
market levels. The Underwriters are not required to engage in these activities,
and may end any of these activities at any time. The Underwriters and dealers
may engage in passive market making transactions in the Common Stock in
accordance with Rule 103 of Regulation M promulgated by the Securities and
Exchange Commission. In general, a passive market maker may not bid for, or
purchase, the Common Stock at a price that exceeds the highest independent bid.
In addition, the net daily purchases made by any passive market maker generally

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors and Stockholders
CORESTAFF, Inc.
 
We have audited the accompanying consolidated balance sheets of CORESTAFF, Inc.
and subsidiaries (the "Company") as of December 31, 1995 and 1996 and the
related consolidated statements of operations, stockholders' equity, and cash
flows for each of the three years in the period ended December 31, 1996. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of CORESTAFF, Inc.
and subsidiaries at December 31, 1995 and 1996 and the consolidated results of
their operations and their cash flows for each of the three years in the period
ended December 31, 1996 in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
     The accompanying consolidated financial statements include the accounts of
CORESTAFF, Inc. (the "Company"), and its wholly-owned subsidiaries. All
significant intercompany accounts and transactions have been eliminated in
consolidation.
 
  Cash and Cash Equivalents
 
     All short-term investments with an original maturity of 90 days or less are
considered cash equivalents.
 
  Fixed Assets
 
     Fixed assets are recorded at cost. Depreciation is computed on a
straight-line basis over the estimated useful lives of the assets. Amortization
of leasehold improvements is computed on a straight-line basis over the useful
life of the asset or lease term, whichever is shorter. Accumulated depreciation
and amortization was $2.6 million and $5.5 million at December 31, 1995 and
1996, respectively.
 
  Intangible Assets
 
     Intangible assets primarily consist of goodwill associated with the
acquired businesses. Goodwill is amortized on a straight-line basis over 40
years. Other intangible assets consist of non-compete agreements, which are
amortized over the term of the agreement. In the event that facts and
circumstances indicate intangible or other long-lived assets may be impaired,
the Company evaluates the recoverability of such assets. The estimated future
undiscounted cash flows associated with the asset are compared to the asset's
carrying amount to determine if a write-down to market value or discounted cash
flow value is necessary.
 
     In the fourth quarter of 1996, the Company recognized a one-time charge to
earnings of $1.4 million for the write-down of goodwill associated with its
physical therapy staffing business, a non-core business that was sold in January
1997. After reflecting this write-down, the Company believes all intangible or
other long-lived assets are fully realizable as of December 31, 1996.
 
  Revenue Recognition
 
     Revenue is recognized at the time the services are provided.
 
  Income Taxes
 
     The Company follows the liability method of accounting for income taxes.
Under this method, deferred income tax assets and liabilities are determined
based on differences between the financial statement and income tax bases of
assets and liabilities using enacted tax rates in effect for the year in which
the differences are expected to reverse.
 
  Self-Insurance
 
     The Company self-insures most of its workers' compensation exposure.
Consulting actuaries are used by the Company to assist in the determination of
its liability, which is calculated using a claims-incurred method.
 
  Earnings per Common Share
 
     Earnings per common share were computed by dividing net income applicable
to common stock (net income less preferred stock dividends in arrears applicable
to the period) by the weighted average number of shares of common stock and
common stock equivalents outstanding during the period giving effect to the
 
                                       F-7

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
dilutive effect of common stock issued within one year prior to the Company's
initial public offering in November 1995 (the "IPO"). Common stock equivalents
consisted of the number of shares issuable on exercise of the outstanding stock
options less the number of shares that could have been purchased with the
proceeds from the exercise of the options based on the average price of the
common stock during the period. The dilutive effect of common stock issued
within one year prior to the IPO for the periods prior to issuance was
determined in the same manner except that the IPO price of $7.55 per share
(which has been adjusted for the two three-for-two stock splits discussed in
Note 5) was used for the repurchase price.
 
     Earnings per common share for 1994 and 1995 as shown in the accompanying
statements of operations were determined in the same manner as described above,
except that the conversion of one-half of the preferred stock into common stock
(See Note 5) was assumed to have occurred as of the beginning of the periods.
Net income applicable to common stock was increased by the dividends in arrears
applicable to the preferred stock converted. Historical earnings per common
share were $0.04 and $0.26 for the years ended December 31, 1994 and 1995,
respectively. Net income applicable to common stock was $748,000 and $5,041,000
for the years ended December 31, 1994 and 1995, respectively.
 
  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 amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Stock Options
 
     The Company follows Accounting Principles Board Opinion No. 25, "Accounting
for Stock Issued to Employees" and related interpretations ("APB 25") in
accounting for its employee stock options. The pro forma disclosures required by
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("SFAS 123"), which established a fair-value based method of
accounting for stock-based compensation plans, are set forth in Note 6.
 
  Reclassifications
 
     Certain reclassifications have been made to the prior years' consolidated
financial statements to conform with the current year presentation.

     In April 1994, the Company acquired United Temporary Services, Incorporated
and United Personnel Systems, a California-based staffing services business, for
$19.9 million in cash. In August 1994, the Company acquired TSTP Corp., a
Maryland-based staffing services business, for $17.3 million in cash. In
September 1994, the Company acquired COMSYS Technical Services, Inc., a
Maryland-based IT services business, for $20.9 million in cash.
 
     In June 1995, the Company acquired Cutler-Williams Incorporated, a
Texas-based IT services business, for $28.3 million in cash.
 
     In January 1996, the Company acquired Datronics Management, Inc., a New
York-based IT services business, and its United Kingdom affiliate, Datronics
U.K. Limited, for $19.2 million in cash. In April 1996, the Company acquired
Regal Data Systems, Inc., a New Jersey-based IT services business, for $21.7
million in cash and a note payable for $0.1 million. In June 1996, the Company
acquired Data Aid, Inc., an Alabama-based IT services business, for $23.2
million in cash. In September 1996, the Company acquired On-Line Resources,
Inc., a Florida-based IT services business, for $17.9 million in cash. In
October 1996, the Company acquired substantially all of the assets of Transworld
Services Group, Inc., a Florida-based staffing services business, for $18.1
million in cash. In December 1996, the Company acquired substantially all of the
assets of Telos Consulting Services, a California-based IT services business,
for $31.4 million in cash.
 
     All the acquisitions made by the Company have been accounted for using the
purchase method of accounting. Accordingly, the results of operations of the
acquired companies are included in the Company's consolidated results of
operations from the date of acquisition. In certain transactions, the sellers
are also entitled to contingent consideration based on the increase in earnings
before interest and taxes ("EBIT"), as defined. As of December 31, 1996, the
Company had accrued $9.6 million for additional purchase consideration due
sellers based on the increase in the acquired companies' EBIT for 1996. The
aggregate contingent consideration due sellers based on increases in EBIT for
future years is capped at $4.5 million. The payment of any contingent

     In November 1996, the Company entered into a new Senior Credit Agreement
(the "Agreement"), which provides for borrowings under a revolving credit
facility of up to the lesser of $200 million or 3.5 times Pro Forma Adjusted
EBITDA (earnings before interest, income taxes, depreciation and amortization of
all acquired companies for the preceding twelve-month period). The Company may
request that the commitment be raised to $250 million. A commitment fee of 0.18%
to 0.25%, depending on the leverage ratio, is payable on the unused portion of
the commitment. The Agreement contains certain covenants which, among other
things, limit the payment of dividends and require the maintenance of certain
financial ratios. The Agreement is secured by a pledge of the stock of the
material subsidiaries of the Company. As of December 31, 1996, the Company had
remaining availability under the Agreement (after deducting outstanding letters
of credit of $4.9 million) of $87.6 million.
 
     In the fourth quarter of 1996, the Company recorded an extraordinary loss
of $1.4 million ($0.9 million after income taxes, or $0.03 per share) in
connection with the early extinguishment of its $130 million revolving credit
facility. This loss related to the write-off of the deferred loan costs of this
facility.

     During 1995, a financial institution, which owns all the Company's Class B
(non-voting) common stock, provided the Company with a $10 million senior
subordinated note. Borrowings under this note accrued interest at LIBOR, plus
4.5 percent. The Company paid an up-front fee of $0.3 million to the institution
for arranging the financing. This note, plus accrued interest, was repaid out of
the proceeds of the IPO.

5. STOCKHOLDERS' EQUITY
 
     Preferred stock. The Company's preferred stock, which was outstanding prior
to the IPO, had a liquidation value of $100 per share and entitled the holders
to receive cumulative dividends at 8% per annum of the sum of the liquidation
value plus all accumulated and unpaid dividends. In November 1995, one-half of
the outstanding shares of preferred stock was converted into common stock at the
IPO price of $7.55 per share and the remainder of the outstanding shares were
redeemed out of the proceeds from the IPO. Dividends in arrears of $2.2 million
were also paid out of the proceeds from the IPO.
 
     Common stock. During 1996, the Board of Directors authorized two
three-for-two stock splits, effected in the form of stock dividends. All
references in the financial statements to number of shares outstanding and
related prices, per share amounts and stock option plan data have been restated
to reflect the stock splits. The stock splits resulted in the issuance of
approximately 16.6 million new shares of common stock and a reclassification of
approximately $0.2 million from retained earnings to common stock representing
the par value of the shares issued.
 
     Under terms of an agreement, 3,420,000 shares of the Company's common stock
were issued to key executives and management. In connection with certain of
these issuances, the Company received notes from the executives as
consideration. These notes, which total $0.9 million and $0.8 million at
December 31, 1995 and 1996, respectively, are secured by the common stock, bear
interest at 8% per year and are due on demand. These shares became fully vested
in connection with the IPO.
 
     In November 1995, the Company completed its IPO of 8,538,750 shares of its
common stock at $7.55 per share. Net proceeds from the IPO were approximately
$59 million. The proceeds were used to (i) redeem the outstanding preferred
stock, plus accrued dividends, (ii) repay the $10 million senior subordinated
note, plus accrued interest, and (iii) pay down of borrowings by approximately
$38 million.
 
     In May 1996, the Company completed a second public offering of 8,259,030
shares (4,950,000 shares sold by the Company and the remainder by certain
selling stockholders) at $29.17 per share. Net proceeds to the Company were
approximately $137.5 million, of which $111.5 million were used to repay
borrowings under the Senior Credit Agreement.

     Supplemental earnings per common share reflect adjustments to the earnings
per common share to give effect to the use of proceeds described above as if the
public offering in May 1996 had occurred at the beginning of 1996. Supplemental
earnings per common share for the year ended December 31, 1996 were $0.57.
 
6. STOCK PLANS
 
     Long-Term Incentive Plan. In August 1995, the Company adopted the 1995
Long-Term Incentive Plan (the "Plan") that provides for the issuance of stock
options, stock appreciation rights, restricted stock, performance share awards,
stock value equivalent awards and cash awards. All full time employees and
directors of the Company or its affiliates are eligible to participate. An
aggregate of 2.7 million shares of common stock has been reserved for issuance
under the Plan. Generally, options granted have ten year terms and vest and
become fully exercisable in three to five years. Stock options issued under the
Plan can be either incentive stock options or non-qualified stock options. The
exercise price of an incentive stock option will not be less than the fair
market value of the common stock on the date the option is granted.
 
     The Company applies APB 25 in accounting for the Plan. Accordingly, no
compensation cost has been recognized for its fixed stock option plan. Pro forma
information regarding net income and earnings per common share is required by
SFAS 123 as if the Company had accounted for its employee stock options under
the fair value method of that statement. The fair value of these options was
estimated at the date of grant using a Black-Scholes option pricing
("Black-Scholes") model with the following weighted average assumptions for 1995
and 1996, respectively: (i) risk-free interest rates of 5.81% and 6.12%, (ii) a
dividend yield of 0%, (iii) volatility factors of the expected market price of
the Company's common stock of 27.5% and (iv) a weighted average expected life of
3 years and 3.75 years.
 
     The Black-Scholes model was developed for use in estimating the fair value
of traded options that have no vesting restrictions and are fully transferable.
In addition, option valuation models require the input of highly subjective
assumptions, including the expected volatility. Because the Company's employee
stock options have characteristics significantly different from those of traded
options and because changes in the subjective input assumptions can materially
affect the fair value estimate, in management's opinion, the existing models do
not necessarily provide a reliable single measure of the fair value of its
employee stock options.
 
     For purposes of pro forma disclosure, the estimated fair value of the
options is amortized to expense over the options' vesting period. Had
compensation for the Company's stock-based compensation plan been determined
based on the fair value at the grant dates for awards under the Plan consistent
with the method of SFAS 123, the Company's net income and earnings per common
share would have been adjusted to the pro forma amounts indicated below:

     Employee Stock Purchase Plan. In 1996, the Company implemented an employee
stock purchase plan whereby eligible employees may purchase shares of the
Company's common stock at a price equal to 85 percent of the lower of the
closing market price on the first or last trading day of a quarter. A total of
450,000 shares of common stock have been reserved for issuance under the plan.
During 1996, employees purchased 33,312 shares for aggregate proceeds to the
Company of $0.7 million.
 
7. COMMITMENTS AND CONTINGENCIES
 
     The Company leases various office space and equipment under noncancelable

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company self-insures most of its workers' compensation exposure.
Consulting actuaries are used by the Company in the determination of its
liability, which is calculated using a claims-incurred method. Using this
method, the present value (using a 5% discount factor) of the estimated
liability for claims incurred but unpaid as of December 31, 1996 was
approximately $4.7 million ($5.0 million undiscounted), of which approximately
$2.4 million was classified as a current liability. As of December 31, 1996, the
Company had irrevocable stand-by letters of credit of approximately $3.9
million, as required by its insurance programs.
 
     Certain of the Company's executives are covered by employment agreements
covering, among other things, base compensation, incentive-bonus determinations
and payments in the event of termination or change in control of the Company.
 
     Under terms of certain acquisitions, the Company is required to make
additional payments to sellers generally to the extent future earnings, as
defined, exceed certain stipulated levels. The provisions of these contingent
payments are described in Note 2.
 
     The Company is a defendant in various lawsuits and claims arising in the
normal course of business. Management believes it has valid defenses in these
cases and is defending them vigorously. While the results of litigation cannot
be predicted with certainty, management believes the final outcome of such
litigation will not have a material effect on the Company.
 
8. RELATED PARTY TRANSACTIONS
 
     Under terms of a professional services agreement, which terminated in
November 1995 following the Company's initial public offering, the general
partner of the Company's largest stockholder provided certain financial and
management consulting services to the Company. Fees paid under this agreement
totaled $85,000 and $127,000 during 1994 and 1995, respectively.
 
     The CEO of the Company owns a minority interest in a firm that provided
investment banking services on certain acquisitions or acquisition targets. Fees
for services rendered were based on rates stipulated in an agreement, which in
the opinion of management, are equivalent to rates charged by unrelated
investment banking firms. Fees paid to this firm during 1994, 1995 and 1996 were
approximately $550,000, $31,000 and $129,000, respectively. The CEO also owns a
50 percent interest in a firm that provided certain charter aircraft services to
the Company. Fees for these services totaled $55,143 in 1996. In the opinion of
management, these fees are based on rates that are comparable to those charged
by third parties.
 
     A bank, which is an affiliate of the financial institution that owns all
the Company's Class B common stock (non-voting), serves as the agent bank for
the Company's Senior Credit Agreement. This bank also provided the Company with
cash management services under terms of a separate agreement.
 
9. CREDIT RISK
 
     The Company provides staffing services to customers in numerous states. A
substantial portion of these sales are in California, Texas and the greater
Washington D.C. area. This concentration could impact the Company's overall
exposure to credit risk inasmuch as these customers could be affected by similar
economic or other conditions. The Company believes its portfolio of accounts
receivable is well diversified and, as a result, its credit risks are minimal.
The Company continually evaluates the creditworthiness of its customers and
monitors accounts on a periodic basis, but typically does not require
collateral.
 
10. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The Company has determined, based on available market information and
appropriate valuation methodologies, that the fair value of its financial
instruments approximates carrying value. The carrying amounts of cash and cash
equivalents, accounts receivable and accounts payable approximate fair value due
to

the short-term maturity of the instruments. The carrying amount of long-term
debt approximates fair value because the interest rates under the credit
agreement are variable, based on current market.

                             (the "Notes") (excluding an additional $27,000,000
                             principal amount if the Underwriters'

                             maturity, payable semiannually in arrears in cash
                             on August   and February   of each year, commencing
                             February   , 1998.
 
Yield to Maturity of
Notes......................       % per annum (computed on a semi-annual bond
                             equivalent basis giving effect both to accrual of

                             calculated from August   , 1997.
 
Conversion.................  Each Note will be convertible, at the option of the
                             holder, at any time after 90 days following the
                             latest date of original issuance thereof through
                             maturity, unless previously redeemed or otherwise
                             purchased by the Company, into Common Stock at the
                             Conversion Rate of   shares per $1,000 principal
                             amount at maturity of the Notes. The Conversion
                             Rate will not be adjusted for accrued Original
                             Issue Discount or interest, but will be subject to
                             adjustment upon the occurrence of certain events
                             affecting the Common Stock. Upon conversion, the
                             holder will not receive any cash payment
                             representing accrued Original Issue Discount or
                             interest; such accrued Original Issue Discount and
                             interest will be deemed paid by the Common Stock
                             received on conversion. See "Description of the
                             Notes -- Conversion of Notes."
 
Subordination..............  The Notes will be subordinated to all existing and
                             future Senior Indebtedness (as defined herein) and
                             pari passu with the Company's indebtedness that is
                             not Senior Indebtedness. The Notes will also be
                             effectively subordinated to all indebtedness and
                             liabilities of subsidiaries of the Company. At June
                             30, 1997, the Company had approximately $
                             million of outstanding Senior Indebtedness. The
                             Company will use the proceeds of the sale of the
                             Notes to repay a portion of the borrowings
                             outstanding under the Credit Agreement. The
                             Indenture does not prohibit or limit the incurrence
                             of additional Senior Indebtedness. See "Risk
                             Factors -- " and "Use of Proceeds."
 
Original Issue Discount....  Each Note is being offered at an Original Issue
                             Discount for federal income tax purposes equal to
                             the excess of the principal amount at maturity of
                             the Note over the amount of its Issue Price.
                             Prospective purchasers of Notes should be aware
                             that accrued Original Issue Discount will be
                             includable periodically in a holder's gross income
                             for federal income tax purposes prior to
                             conversion, redemption, other disposition or
                             maturity of such holder's Notes, whether or not
                             such Notes are ultimately converted, redeemed, sold
                             (to the Company or otherwise) or paid at maturity.

                             thereof) of such holder's Notes at declining

[NOTE: THESE RISK FACTORS SUPPLEMENT THE RISK FACTORS CONTAINED IN THE COMMON
       STOCK PROSPECTUS.]
 
SUBORDINATION
 
     The Notes will be unsecured and subordinated in right of payment in full to
all existing and future Senior Indebtedness of the Company. As a result of such
subordination, in the event of bankruptcy, liquidation or reorganization of the
Company or upon acceleration of the Notes due to an event of default, the assets
of the Company would be available to pay obligations on the Notes only after all
Senior Indebtedness had been paid in full, and there might not be sufficient
assets remaining to pay amounts due on any or all of the Notes then outstanding.
The Notes are structurally subordinated to the liabilities, including trade
payables, of the Company subsidiaries. The Indenture does not prohibit or limit
the incurrence of Senior Indebtedness or the incurrence of other indebtedness
and other liabilities by the Company or its subsidiaries, and the incurrence of
additional indebtedness and other liabilities by the Company or its subsidiaries
could adversely affect the Company's ability to pay its obligations on the
Notes. At             , 1997, the Company had approximately $     million of
outstanding Senior Indebtedness. The Company anticipates that from time to time
it will incur additional indebtedness, including Senior Indebtedness, and that
its subsidiaries will form time to time incur other additional indebtedness and
liabilities. See "Description of the Notes -- Subordination of Notes" and "Use
of Proceeds."
 
LIMITATIONS ON REDEMPTION OF NOTES
 
     Upon a Fundamental Change, each holder of Notes will have certain rights,
at the holder's option, to require the Company to redeem all or a portion of
such holder's Notes. If a Fundamental Change were to occur, there can be no
assurance that the Company would have sufficient funds to pay the redemption
price of all Notes tendered. Any future credit agreements or other agreements
(including those relating to Senior Indebtedness) may contain provisions
restricting the purchase or redemption of the Notes. In the event a Fundamental
Change occurs at a time when the Company is prohibited from purchasing or
redeeming the Notes, the Company could seek the consent of its lenders to the
purchase of the Notes or could attempt to refinance the borrowings that contain
such prohibition. If the Company does not obtain such a consent or repay such
borrowings, the Company would remain prohibited from purchasing or redeeming
Notes. In such case, the Company's failure to redeem tendered Notes would
constitute an Event of Default under the Indenture, which might, in turn,
constitute a default under the terms of agreements relating to other
indebtedness that the Company may enter into from time to time. In such
circumstances, the subordination provisions in the Indenture would likely
restrict payments to the holders of the Notes. See "Description of the
Notes -- Redemption at Option of the Holder."
 
ABSENCE OF PUBLIC MARKET FOR THE NOTES
 
     Prior to the Notes Offering, there has been no trading market for the
Notes. Although the Underwriters have advised the Company that they currently
intend to make a market in the Notes, they are not obligated to do so and may
discontinue such market making at any time without notice. In addition, such
market making activity will be subject to the limits imposed by the Securities
Act and the Exchange Act. Accordingly, there can be no assurance that any market
for the Notes will develop or, if one does develop, that it will be maintained.
If an active market for the Notes fails to develop or be sustained, the trading
price of such Notes could be materially adversely affected.
 
                                       A-6
<PAGE>   77
 
                                USE OF PROCEEDS
 
     The net proceeds to be received by the Company from the sale of the Notes,
after deducting the expenses of this offering, are estimated to be approximately
$     million. The net proceeds are expected to be used to repay $     million
of the outstanding indebtedness under the Credit Agreement. At             ,
1997, the aggregate outstanding balance under the Credit Agreement was $
million. Borrowing under the Credit Agreement bears interest, at the Company's
option, at LIBOR plus a margin of 0.625% to 1.375%, which depends upon the
leverage ratio, or the bank's base rate. A commitment fee of 0.18% to 0.25%,
depending on the leverage ratio, is payable on the unused portion of the
facility. The weighted average interest rate of the Company's outstanding
borrowings under the Credit Agreement was     % at June 30, 1997. Amounts
currently outstanding under the Credit Agreement were incurred to fund
acquisitions, capital expenditures and general corporate purposes. Amounts
repaid on the Credit Agreement may be reborrowed from time to time for possible
future acquisitions, capital expenditures and other general corporate purposes.
 
                            DESCRIPTION OF THE NOTES
 
     The Notes will be issued under an indenture to be dated as of August   ,
1997 (the "Indenture"), between the Company and The Bank of New York, as trustee
(the "Trustee"). A copy of the Indenture (as defined below) will be available
from the Trustee upon request by a registered holder of the Notes. The following
summaries of certain provisions of the Notes and the Indenture do not purport to
be complete and are subject to, and are qualified in their entirety by reference
to, all the provisions of the Notes and the Indenture, including the definitions
therein of certain terms which are not otherwise defined in this Prospectus.
Wherever particular provisions or defined terms of the Indenture (or of the form
of Note which is a part thereof) are referred to, such provisions or defined
terms are incorporated herein by reference.
 
GENERAL
 
     The Notes represent unsecured general obligations of the Company
subordinate in right of payment to certain other obligations of the Company as
described under "Subordination of Notes" and convertible into Common Stock as
described under "Conversion of Notes." The Notes will be limited to $180,000,000
($207,000,000 if the Underwriters' over-allotment option is exercised in full)
aggregate principal amount, will be issued only in denominations of $1,000 or
any multiple thereof and will mature on August   , 2004, unless earlier redeemed
at the option of the Company or at the option of the holder upon a Fundamental
Change (as defined below).
 
     The Indenture does not contain any financial covenants or restrictions on
the payment of dividends, the incurrence of Senior Indebtedness (as defined
below under "Subordination of Notes") or the issuance or repurchase of
securities of the Company. The Indenture contains no covenants or other
provisions to afford protection to holders of the Notes in the event of a highly
leveraged transaction or a change in control of the Company except to the extent
described under "Redemption at Option of the Holder."
 
     The Notes will bear interest at the annual rate set forth on the cover page
hereof from August      , 1997, payable semi-annually on February   and August
  , commencing on February   , 1998, to holders of record at the close of
business on the preceding January   and July   , respectively, except (i) that
the interest payment upon redemption (unless the date of redemption is an
interest payment date) will be payable to the person to whom principal is
payable and (ii) as set forth in the next succeeding sentence. In the case of
any Note (or portion thereof) which is converted into Common Stock of the
Company during the period from (but excluding) a record date to (but excluding)
the next succeeding interest payment date either (i) if such Note (or portion
thereof) has been called for redemption on a redemption date which occurs during
such period, or is to be redeemed in connection with a Fundamental Change on a
Fundamental Change Repurchase Date (as defined below) which occurs during such
period, the Company shall not be required to pay interest on such interest
payment date in respect of any such Note (or portion thereof) or (ii) if
otherwise, any Note (or portion thereof) submitted for conversion during such
period shall be accompanied by funds equal to the interest payable on such
succeeding interest payment date on the aggregate principal amount so converted
(see "Conversion of Notes" below). Interest may, at the Company's option, be
paid either (i) by check mailed to the address of the person entitled thereto as
it appears in the Note register or (ii) by transfer to an
 
                                       A-7
<PAGE>   78
 
account maintained by such person located in the United States; provided,
however, that payments to The Depository Trust Company, New York, New York
("DTC") will be made by wire transfer of immediately available funds to the
account of DTC or its nominee. Interest will be computed on the basis of a
360-day year composed of twelve 30-day months.
 
     The Notes are being offered at a substantial discount from their principal
amount at maturity. See "Certain United States Federal Income Tax
Considerations." The calculation of the accrual of Original Issue Discount (the
difference between the Issue Price and the principal amount at maturity of a
Note) in the period during which a Note remains outstanding will be on a
semi-annual bond equivalent basis using a year composed of twelve 30-day months;
such accrual will commence on the first date of issuance of any of the Notes.
Maturity, conversion or redemption of a Note will cause Original Issue Discount
and interest, if any, to cease to accrue on such Note under the terms and
subject to the conditions of the Indenture. The Company may not reissue a Note
that has matured or been converted, redeemed or otherwise cancelled (except for
registration of transfer, exchange or replacement thereof).
 
     Application will be made to list the Notes on the Nasdaq National Market
under the symbol "     ."
 
BOOK ENTRY; DELIVERY AND FORM
 
     The Notes will be issued in fully registered form, without coupons, in
denominations of $1,000 principal amount at maturity and multiples thereof.
 
     The Notes will be evidenced by one or more global notes (each a "Global
Note"), which will be deposited with, or on behalf of, DTC and registered in the
name of Cede & Co. ("Cede") as DTC's nominee.
 
     Except as set forth below, the Global Note may be transferred, in whole or
in part, only to another nominee of DTC or to a successor of DTC or its nominee.
Non-U.S. Persons, if any, will be required to hold their Notes in definitive
registered form. As a result, the ability to transfer beneficial interests in
such Notes may be limited.
 
     Non-U.S. Persons who are not Participants may beneficially own interests in
Global Notes held by DTC only through Participants, including Morgan Guaranty
Trust Company of New York, Brussels office, as operator of the Euroclear System
("Euroclear") and Cedel, S.A. ("Cedel"), or certain banks, brokers, dealers,
trust companies and other parties that clear through or maintain a custodial
relationship with a Participant, either directly or indirectly ("Indirect
Participants"). So long as Cede, as the nominee of DTC, is the registered owner
of the Global Note, Cede for all purposes will be considered the sole holder of
the Global Note. Except as provided below, owners of beneficial interests in the
Global Note will not be entitled to have certificates registered in their names,
will not receive or be entitled to receive physical delivery of certificates in
definitive form, and will not be considered the holders thereof.
 
     Payment of interest on and the redemption price of the Global Note will be
made to Cede, the nominee for DTC, as the registered owner of the Global Note by
wire transfer of immediately available funds on each interest payment date or
the redemption date, as the case may be. Neither the Company, the Trustee nor
any paying agent will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests in the Global Note or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.
 
     The Company has been informed by DTC that, with respect to any payment of
interest on, or the redemption price of, the Global Note, DTC's practice is to
credit Participants' accounts on the payment date therefor with payments in
amounts proportionate to their respective beneficial interests in the principal
amount represented by the Global Note as shown on the records of DTC, unless DTC
has reason to believe that it will not receive payment on such payment date.
Payments by Participants to owners of beneficial interests in the principal
amount represented by the Global Note held through such Participants will be the
responsibility of such Participants, as is now the case with securities held for
the accounts of customers registered in "street name."
 
                                       A-8
<PAGE>   79
 
     Because DTC can only act on behalf of Participants, who in turn act on
behalf of Indirect Participants and certain banks, the ability of a person
having a beneficial interest in the principal amount represented by the Global
Note to pledge such interest to persons or entities that do not participate in
the DTC system, or otherwise take actions in respect of such interest, may be
affected by the lack of a physical certificate evidencing such interest.
 
     Neither the Company nor the Trustee (or any registrar, paying agent or
conversion agent under the Indenture) will have any responsibility for the
performance by DTC or its Participants or Indirect Participants of their
respective obligations under the rules and procedures governing their
operations. DTC has advised the Company that it will take any action permitted
to be taken by a holder of Notes (including, without limitation, the
presentation of Notes for exchange as described below), only at the direction of
one or more Participants to whose account with DTC interests in the Global Note
are credited, and only in respect of the principal amount of the Notes
represented by the Global Note as to which such Participant or Participants has
or have given such direction.
 
     DTC has advised the Company as follows: DTC is a limited purpose trust
company organized under the New York Banking Law, a "banking organization"
within the meaning of the New York Banking Law, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the New York Uniform
Commercial Code and a "clearing agency" registered pursuant to the provisions of
Section 17A of the Exchange Act. DTC holds securities that its Participants
deposit with DTC. DTC also facilitates the clearance and settlement of
securities transactions between Participants through electronic book-entry
changes to the accounts of its Participants, thereby eliminating the need for
physical movement of certificates. Participants include securities brokers and
dealers, banks, trust companies and clearing corporations. Certain of such
Participants (or their representatives), together with other entities, own DTC.
Indirect access to the DTC system is available to others such as banks, brokers,
dealers and trust companies that clear through, or maintain a custodial
relationship with, a Participant, either directly or indirectly.
 
     Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in the Global Note among Participants, it is under no
obligation to perform or continue to perform such procedures, and such
procedures may be discontinued at any time. If DTC is at any time unwilling or
unable to continue as depositary and a successor depositary is not appointed by
the Company within 90 days, the Company will cause the Notes to be issued in
definitive form in exchange for the Global Note.
 
     Certificated Notes. Notes sold to investors that are Non-U.S. Persons will
be issued in definitive registered form and may not be represented by the Global
Note. In addition, holders of Notes may request that certificated Notes be
issued in exchange for Notes represented by the Global Note. Furthermore,
certificated Notes may be issued in exchange for Notes represented by the Global
Note if no successor depositary is appointed by the Company as set forth above
under "Book-Entry; Delivery and Form."
 
CONVERSION OF NOTES
 
     A Noteholder may convert a Note into Common Stock of the Company at any
time after 90 days following the latest date of original issuance of the Notes
through the close of business on the final maturity date of the Notes; provided
that if a Note is called for redemption, the holder may convert such Note only
until the close of business on the day prior to the Redemption Date. A Note in
respect of which a holder is exercising its option to require redemption upon a
Fundamental Change may be converted only if such holder withdraws its election
to exercise its option in accordance with the terms of the Indenture. A holder
may convert such holder's Notes in part so long as such part is $1,000 principal
amount at maturity or an integral multiple thereof. If Notes not called for
redemption are converted after a record date for the payment of interest and
prior to the next succeeding interest payment date, such Notes must be
accompanied by funds equal to the interest payable on such succeeding interest
payment date on the principal amount at maturity so converted provided that no
such payment will be required if the Company exercises its rights to redeem the
Notes.
 
     The initial Conversion Rate is      shares of Common Stock per $1,000
principal amount at maturity of Notes, subject to adjustment upon the occurrence
of certain events. A Noteholder who would otherwise be entitled to a fractional
share of Common Stock shall receive cash equal to the then current market value
of
 
                                       A-9
<PAGE>   80
 
such fractional share. On conversion of a Note, a holder will not receive any
cash payment representing accrued Original Issue Discount or accrued interest
thereon. The Company's delivery to the holder of the fixed number of shares of
Common Stock into which the Note is convertible (together with the cash payment
in lieu of any fractional share of Common Stock) will be deemed to satisfy the
Company's obligation to pay the principal amount of the Note including the
accrued Original Issue Discount attributable to the period from the first date
of issuance of any of the Notes to the date of surrender for conversion and
accrued interest thereon. Thus, the accrued Original Issue Discount and accrued
interest are deemed to be paid in full rather than canceled, extinguished or
forfeited. The Conversion Rate will not be adjusted at any time during the term
of the Notes for such accrued Original Issue Discount or accrued interest.
 
     To convert a Note into shares of Common Stock, the Holder of a Note must
(i) complete and manually sign the conversion notice on the back of the Note (or
complete and manually sign a facsimile thereof) and deliver such notice to the
Conversion Agent, (ii) surrender the Note to the Conversion Agent, (iii) if
required, furnish appropriate endorsements and transfer documents, (iv) if
required, pay all transfer or similar taxes, and (v) if required, pay funds
equal to interest payable on the next interest payment date. Pursuant to the
Indenture, the date on which all of the foregoing requirements have been
satisfied is the date of surrender for conversion.
 
     The initial Conversion Rate is subject to adjustment under formulae as set
forth in the Indenture in certain events, including:
 
          (i) the issuance of Common Stock of the Company as a dividend or
     distribution on the Common Stock;
 
          (ii) certain subdivisions and combinations of the Common Stock;
 
          (iii) the issuance to all holders of Common Stock of certain rights or
     warrants to purchase Common Stock;
 
          (iv) the distribution to all holders of Common Stock of capital stock
     (other than Common Stock), of evidences of indebtedness of the Company or
     of assets (including securities, but excluding those rights, warrants,
     dividends and distributions referred to in clause (iii) above or paid in
     cash);
 
          (v) distributions consisting of cash, excluding any quarterly cash
     dividend on the Common Stock to the extent that the aggregate cash dividend
     per share of Common Stock in any quarter does not exceed the greater of (x)
     the amount per share of Common Stock of the next preceding quarterly cash
     dividend on the Common Stock to the extent that such preceding quarterly
     dividend did not require an adjustment of the Conversion Rate pursuant to
     this clause (v) (as adjusted to reflect subdivisions or combinations of the
     Common Stock), and (y) 3.75 percent of the average of the last reported
     sales price of the Common Stock during the ten trading days immediately
     prior to the date of declaration of such dividend, and excluding any
     dividend or distribution in connection with the liquidation, dissolution or
     winding up of the Company. If an adjustment is required to be made as set
     forth in this clause (v) as a result of a distribution that is a quarterly
     dividend, such adjustment would be based upon the amount by which such
     distribution exceeds the amount of the quarterly cash dividend permitted to
     be excluded pursuant to this clause (v). If an adjustment is required to be
     made as set forth in this clause (v) as a result of a distribution that is
     not a quarterly dividend, such adjustment would be based upon the full
     amount of the distribution;
 
          (vi) payment in respect of a tender offer or exchange offer by the
     Company or any subsidiary of the Company for the Common Stock to the extent
     that the cash and value of any other consideration included in such payment
     per share of Common Stock exceeds the Current Market Price (as defined in
     the Indenture) per share of Common Stock on the trading day next succeeding
     the last date on which tenders or exchanges may be made pursuant to such
     tender or exchange offer; and
 
          (vii) payment in respect of a tender offer or exchange offer by a
     person other than the Company or any subsidiary of the Company in which, as
     of the closing date of the offer, the Board of Directors is not
     recommending rejection of the offer. The adjustment referred to in this
     clause (vii) will only be made if
 
                                      A-10
<PAGE>   81
 
     the tender offer or exchange offer is for an amount which increases the
     offeror's ownership of Common Stock to more than 25% of the total shares of
     Common Stock outstanding, and if the cash and value of any other
     consideration included in such payment per share of Common Stock exceeds
     the Current Market Price per share of Common Stock on the business day next
     succeeding the last date on which tenders or exchanges may be made pursuant
     to such tender or exchange offer. The adjustment referred to in this clause
     (vii) will generally not be made, however, if, as of the closing of the
     offer, the offering documents with respect to such offer disclose a plan or
     an intention to cause the Company to engage in a consolidation or merger of
     the Company or a sale of all or substantially all of the Company's assets.
 
     In the case of (i) any reclassification of the Common Stock, or (ii) a
consolidation, merger or combination involving the Company or a sale or
conveyance to another person of the property and assets of the Company as an
entirety or substantially as an entirety, in each case as a result of which
holders of Common Stock shall be entitled to receive stock, other securities,
other property or assets (including cash) with respect to or in exchange for
such Common Stock, the holders of the Notes then outstanding will generally be
entitled thereafter to convert such Notes into the kind and amount of shares of
stock, other securities or other property or assets which they would have owned
or been entitled to receive upon such reclassification, change, consolidation,
merger, combination, sale or conveyance had such Notes been converted into
Common Stock immediately prior to such reclassification, consolidation, merger,
combination, sale or conveyance assuming that a holder of Notes would not have
exercised any rights of election as to the stock, other securities or other
property or assets receivable in connection therewith.
 
     In the event of a taxable distribution to holders of Common Stock or in
certain other circumstances requiring Conversion Rate adjustments, the holders
of Notes may, in certain circumstances, be deemed to have received a
distribution subject to United States income tax as a dividend; in certain other
circumstances, the absence of such an adjustment may result in a taxable
dividend to the holders of Common Stock. See "Certain United States Federal
Income Tax Considerations."
 
     The Company from time to time may, to the extent permitted by law, increase
the Conversion Rate by any amount for any period of at least 20 days, in which
case the Company shall give at least 15 days' notice of such increase if the
Company's Board of Directors has made a determination that such increase would
be in the best interests of the Company, which determination shall be
conclusive. The Company may, at its option, make such increases in the
Conversion Rate, in addition to those set forth above, as the Board of Directors
deems advisable to avoid or diminish any income tax to holders of Common Stock
resulting from any dividend or distribution of stock (or rights to acquire
stock) or from any event treated as such for income tax purposes. See "Certain
United States Federal Income Tax Considerations."
 
     No adjustment in the Conversion Rate will be required unless such
adjustment would require a change of at least 1 percent in the Conversion Rate
then in effect; provided that any adjustment that would otherwise be required to
be made shall be carried forward and taken into account in any subsequent
adjustment. Except as stated above, the Conversion Rate will not be adjusted for
the issuance of Common Stock or any securities convertible into or exchangeable
for Common Stock or carrying the right to purchase any of the foregoing.
 
     The Indenture will provide that if the Company implements a stockholders'
rights plan, such rights plan must provide that upon conversion of the Notes the
holders will receive, in addition to the Common Stock issuable upon such
conversion, such rights whether or not such rights have separated from the
Common Stock at the time of such conversion.

OPTIONAL REDEMPTION BY THE COMPANY
 
     No sinking fund is provided for the Notes. Prior to August   , 2000, the
Notes will not be redeemable at the option of the Company. At any time on or
after such date, the Company may redeem the Notes for cash as a whole at any
time, or from time to time in part at the applicable Redemption Price together
with accrued interest to, but excluding, the date fixed for redemption; provided
that any semi-annual payment of interest becoming due on the date fixed for
redemption shall be payable to the holders of such Notes registered on the
relevant record date. Not less than 30 days' nor more than 60 days' notice of
redemption shall be given by mail to holders of Notes. The Notes will be
redeemable in integral multiples of $1,000 principal amount at maturity.
 
     The table below shows Redemption Prices of a Note per $1,000 principal
amount at maturity, at August   , 2000, at each August   thereafter prior to
maturity and at maturity on August   , 2004, which prices reflect the accrued
Original Issue Discount calculated to each such date. The Redemption Price of a
Note redeemed between such dates would include an additional amount reflecting
the additional Original Issue Discount accrued since the next preceding date in
the table to the actual Redemption Date.

     If less than all of the outstanding Notes are to be redeemed, the Trustee
shall select the Notes to be redeemed in principal amounts of $1,000 or
multiples thereof by lot, pro rata or by another method the Trustee considers
fair and appropriate. If a portion of a holder's Notes is selected for partial
redemption and such holder converts a portion of such Notes, such converted
portion shall be deemed to be of the portion selected for redemption.
 
REDEMPTION AT OPTION OF THE HOLDER
 
     If a Fundamental Change (as defined below) occurs at any time prior to
August   , 2004, each Noteholder shall have the right, at the holder's option,
to require the Company to redeem any or all of such holder's Notes on the date
(the "Fundamental Change Repurchase Date") that is 30 days after the date of the
Company's notice of such Fundamental Change. The Notes will be redeemable in
multiples of $1,000 principal amount at maturity.
 
     The Company shall redeem such Notes at a price (the "Fundamental Change
Repurchase Price") equal to (i) $          if the Fundamental Change Repurchase
Date is August      , 1997, (ii) $          if the Fundamental Change Repurchase
Date is August   , 1998, (iii) $          if the Fundamental Change Repurchase
Date is August   , 1999 and (iv) thereafter at the redemption price set forth
under "Optional Redemption by the Company" which would be applicable to a
redemption at the option of the Company on the Fundamental Change Repurchase
Date; provided, that if the Fundamental Change Repurchase Date is between such
dates, the Fundamental Change Repurchase Price would include an additional
amount reflecting the additional Original Issue Discount accrued since the
preceding August   (or August   , if applicable). Notwithstanding the foregoing,
if the Applicable Price (as defined) is less than the Reference Market Price (as
defined), the Company shall redeem such Notes at a price equal to the foregoing
redemption price multiplied by the fraction obtained by dividing the Applicable
Price by the Reference Market Price. In each case, the Company shall also pay
accrued interest on the redeemed Notes to, but excluding, the Fundamental Change
Repurchase Date; provided that, if such Fundamental Change Repurchase Date is an
interest payment date, then the interest payable on such date shall be paid to
the holder of record of the Notes on the relevant record date.
 
                                      A-12

     The Company is required to mail to all holders of record of the Notes a
notice of the occurrence of a Fundamental Change and of the redemption right
arising as a result thereof on or before the tenth day after the occurrence of
such Fundamental Change. The Company is also required to deliver to the Trustee
a copy of such notice. To exercise the redemption right, a holder of Notes must
deliver, on or before the 30th day after the date of the Company's notice of a
Fundamental Change (the "Fundamental Change Expiration Time"), written notice of
the holder's exercise of such right, together with the Notes to be so redeemed,
duly endorsed for transfer, to the Company (or an agent designated by the
Company for such purpose). Payment for Notes surrendered for redemption (and not
withdrawn) prior to the Fundamental Change Expiration Time will be made promptly
following the Fundamental Change Repurchase Date.
 
     The term "Fundamental Change" means the occurrence of any transaction or
event in connection with which all or substantially all Common Stock shall be
exchanged for, converted into, acquired for or constitute the right to receive
consideration (whether by means of an exchange offer, liquidation, tender offer,
consolidation, merger, combination, reclassification, recapitalization or
otherwise) which is not all or substantially all common stock listed (or, upon
consummation of or immediately following such transaction or event, which will
be listed) on a United States national securities exchange or approved for
quotation on the Nasdaq National Market or any similar United States system of
automated dissemination of quotations of securities prices.
 
     The term "Applicable Price" means (i) in the event of a Fundamental Change
in which the holders of Common Stock receive only cash, the amount of cash
received by the holder of one share of Common Stock and (ii) in the event of any
other Fundamental Change, the average of the last reported sale price for the
Common Stock during the ten trading days prior to the record date for the
determination of the holders of Common Stock entitled to receive cash,
securities, property or other assets in connection with such Fundamental Change,
or, if there is not such record date, the date upon which the holders of the
Common Stock shall have the right to receive such cash, securities, property or
other assets in connection with the Fundamental Change.
 
     The term "Reference Market Price" shall initially mean $       (which is
equal to 66 2/3% of the last sale price of the Common Stock as reflected on the
cover page of this Prospectus) and, in the event of any adjustment to the
Conversion Rate described above pursuant to the provisions of the Indenture, the
Reference Market Price shall also be adjusted so that the Reference Market Price
after giving effect to any such adjustment shall equal the Reference Market
Price multiplied by a fraction, the numerator of which is the Conversion Rate
prior to such adjustment and the denominator of which is the Conversion Rate
after such adjustment.
 
     The Company will comply with the provisions of Rule 13e-4 and any other
tender offer rules under the Exchange Act which may then be applicable in
connection with the redemption rights of Note holders in the event of a
Fundamental Change. The redemption rights of the holders of Notes could
discourage a potential acquiror of the Company. The Fundamental Change
redemption feature, however, is not the result of management's knowledge of any
specific effort to obtain control of the Company by means of a merger, tender
offer, solicitation or otherwise, or part of a plan by management to adopt a
series of anti-takeover provisions.
 
     The Company could, in the future, enter into certain transactions,
including certain recapitalizations of the Company, that would not constitute a
Fundamental Change, but that would increase the amount of indebtedness,
including Senior Indebtedness, outstanding at such time. Further, payment of the
Fundamental Change Repurchase Price on the Notes may be subordinated to the
prior payment of Senior Indebtedness as described under "Subordination of Notes"
below. There are no restrictions in the Indenture on the creation of additional
Senior Indebtedness or other indebtedness. Under certain circumstances, the
incurrence of additional indebtedness could have an adverse effect on the
Company's ability to service its indebtedness, including the Notes. If a
Fundamental Change were to occur, there can be no assurance that the Company
would have sufficient funds to pay the Fundamental Change Redemption Price for
all Notes tendered by the holders thereof. A default by the Company on its
obligations to pay the Fundamental Change Repurchase Price could result in
acceleration of the payment of other indebtedness of the Company at the time
outstanding pursuant to cross-default provisions.

SUBORDINATION OF NOTES
 
     The Indebtedness evidenced by the Notes is subordinated to the extent
provided in the Indenture to the prior payment in full of all Senior
Indebtedness. The Notes will also be effectively subordinated to all
indebtedness and liabilities of subsidiaries of the Company. Upon any
distribution of assets of the Company upon any dissolution, winding up,
liquidation or reorganization, the payment of the principal of, premium, if any,
and interest on the Notes is to be subordinated to the extent provided in the
Indenture in right of payment to the prior payment in full in cash of all Senior
Indebtedness. In the event of any acceleration of the Notes because of an Event
of Default (as defined in the Indenture), the holders of any Senior Indebtedness
then outstanding would be entitled to payment in full in cash of all obligations
in respect of such Senior Indebtedness before the holders of the Notes are
entitled to receive any payment or distribution in respect thereof. The
Indenture will require that the Company promptly notify holders of Senior
Indebtedness if payment of the Notes in accelerated because of an Event of
Default.
 
     The Company also may not make any payment upon or in respect of the Notes
if (i) a default in the payment of the principal of, premium, if any, interest,
rent or other obligations in respect of Senior Indebtedness occurs and is
continuing beyond any applicable period of grace or (ii) any other default
occurs and is continuing with respect to Designated Senior Indebtedness (as
defined) that permits holders of the Designated Senior Indebtedness as to which
such default relates to accelerate its maturity and the Trustee receives a
notice of such default (a "Payment Blockage Notice") from the Company or other
person permitted to give such notice under the Indenture. Payments on the Notes
may and shall be resumed (a) in case of a payment default, upon the date on
which such default is cured or waived and (b) in case of a nonpayment default,
the earlier of the date on which such nonpayment default is cured or waived or
179 days after the date on which the applicable Payment Blockage Notice is
received. No new period of payment blockage may be commenced pursuant to a
Payment Blockage Notice unless and until (i) 365 days have elapsed since the
initial effectiveness of the immediately prior Payment Blockage Notice and (ii)
all scheduled payments of principal, premium, if any, and interest on the Notes
that have come due have been paid in full in cash. During any period of payment
blockage, any payment that otherwise would have been made during such period
will accrue interest, to the extent legally permissible, at the annual rate set
forth on the cover page hereof from the date on which such payment was required
under the terms of the Indenture until the date of payment. No nonpayment
default that existed or was continuing on the date of delivery of any Payment
Blockage Notice to the Trustee shall be, or shall be made, the basis for a
subsequent Payment Blockage Notice.
 
     By reason of the subordination provisions described above, in the event of
the Company's bankruptcy, dissolution or reorganization, holders of Senior
Indebtedness may receive more, ratably, and holders of the Notes may receive
less, ratably, than the other creditors of the Company. Such subordination will
not prevent the occurrence of any Event of Default under the Indenture.
 
     The term "Senior Indebtedness" means the principal of, premium, if any,
interest (including all interest accruing subsequent to the commencement of any
bankruptcy or similar proceeding, whether or not a claim for post-petition
interest is allowable as a claim in any such proceeding) and rent payable on or
in connection with, and all fees, cost, expenses and other amounts accrued or
due on or in connection with, Indebtedness (as defined below) of the Company,
whether outstanding on the date of this Indenture or thereafter created,
incurred, assumed, guaranteed or in effect guaranteed by the Company (including
all deferrals, renewals, extensions or refundings of, or amendments,
modifications or supplements to, the foregoing), unless in the case of any
particular Indebtedness the instrument creating or evidencing the same or the
assumption or guarantee thereof expressly provides that such Indebtedness shall
not be senior in right of payment to the Notes or expressly provides that such
Indebtedness is pari passu with or junior to the Notes. Notwithstanding the
foregoing, the term Senior Indebtedness shall not include any Indebtedness of
the Company to any subsidiary of the Company, a majority of the voting stock of
which is owned, directly or indirectly, by the Company.
 
                                      A-14
<PAGE>   85
 
     The term "Indebtedness" means, with respect to any Person (as defined in
the Indenture), and without duplication:
 
          (a) all indebtedness, obligations and other liabilities (contingent or
     otherwise) of such Person for borrowed money (including obligations of the
     Company in respect of overdrafts, foreign exchange contracts, currency
     exchange agreements, interest rate protection agreements, and any loans or
     advances from banks, whether or not evidenced by notes or similar
     instruments) or evidenced by bonds, debentures, notes or similar
     instruments (whether or not the recourse of the lender is to the whole of
     the assets of such Person or to only a portion thereof) (other than any
     account payable or other accrued current liability or obligation incurred
     in the ordinary course of business in connection with the obtaining of
     materials or service),
 
          (b) all reimbursement obligations and other liabilities (contingent or
     otherwise) of such Person with respect to letters of credit, bank
     guarantees or bankers' acceptances,
 
          (c) all obligations and liabilities (contingent or otherwise) in
     respect of leases of such Person required, in conformity with generally
     accepted accounting principles, to be accounted for as capitalized lease
     obligations on the balance sheet of such Person and all obligations and
     other liabilities (contingent or otherwise) under any lease or related
     document (including a purchase agreement) in connection with the lease of
     real property which provides that such Person is contractually obligated to
     purchase or cause a third party to purchase the leased property and thereby
     guarantee a minimum residual value of the leased property to the lessor and
     the obligations of such Person under such lease or related document to
     purchase or to cause a third party to purchase such leased property,
 
          (d) all obligations of such Person (contingent or otherwise) with
     respect to an interest rate or other swap, cap or collar agreement or other
     similar instrument or agreement or foreign currency hedge, exchange,
     purchase or similar instrument or agreement,
 
          (e) all direct or indirect guaranties or similar agreements by such
     Person in respect of, and obligations or liabilities (contingent or
     otherwise) of such Person to purchase or otherwise acquire or otherwise
     assure a creditor against loss in respect of, indebtedness, obligations or
     liabilities of another Person of the kind described in clauses (a) through
     (d),
 
          (f) any indebtedness or other obligations described in clauses (a)
     through (d) secured by any mortgage, pledge, lien or other encumbrance
     existing on property which is owned or held by such Person, regardless of
     whether the indebtedness or other obligation secured thereby shall have
     been assumed by such Person, and
 
          (g) any and all deferrals, renewals, extensions and refundings of, or
     amendments, modifications or supplements to, any indebtedness, obligation
     or liability of the kind described in clauses (a) through (f).
 
     The term "Designated Senior Indebtedness" means any particular Senior
Indebtedness in which the instrument creating or evidencing the same or the
assumption or guarantee thereof (or related agreements or documents to which the
Company is a party) expressly provides that such Senior Indebtedness shall be
"Designated Senior Indebtedness" for purposes of the Indenture (provided that
such instrument, agreement or other document may place limitations and
conditions on the right of such Senior Indebtedness to exercise the rights of
Designated Senior Indebtedness).
 
     At June 30, 1997, the Company had approximately $217 million of outstanding
Senior Indebtedness. The Company intends to use the proceeds of the sale of the
Notes to repay a portion of the borrowings outstanding under the Company's
Credit Agreement. The Indenture will not limit the amount of additional
Indebtedness, including Senior Indebtedness, which the Company can create,
incur, assume or guarantee, nor will the Indenture limit the amount of
indebtedness or liabilities which any subsidiary can create, incur, assume or
guarantee.
 
     In the event that, notwithstanding the foregoing, the Trustee or any holder
of the Notes receives any payment or distribution of assets of the Company or
any kind in contravention of any of the subordination provisions of the
Indenture, whether in cash, property or securities, including, without
limitation, by way of
 
                                      A-15
<PAGE>   86
 
set-off or otherwise, in respect of the Notes before all Senior Indebtedness is
paid in full, then such payment or distribution will be held by the recipient in
trust for the benefit of holders of Senior Indebtedness or their representatives
to the extent necessary to make payment in full of all Senior Indebtedness
remaining unpaid, after giving effect to any concurrent payment or distribution,
or provision therefor, to or for the holders of Senior Indebtedness.
 
     The Company is obligated to pay reasonable compensation to the Trustee and
to indemnify the Trustee against certain losses, liabilities or expenses
incurred by it in connection with its duties relating to the Notes. The
Trustee's claims for such payments will generally be senior to those of holders
of the Notes in respect of all funds collected or held by the Trustee.
 
EVENTS OF DEFAULT; NOTICE AND WAIVER
 
     An Event of Default is defined in the Indenture as being: (i) default for
30 days in payment of any installment of interest on any Note (whether or not
payment is prohibited by the subordination provisions of the Indenture); (ii)
default in payment of the principal amount at maturity, Issue Price, accrued
Original Issue Discount, Redemption Price or Fundamental Change Repurchase
Price, with respect to any Note when such becomes due and payable; (iii) default
by the Company for 30 days after notice in the observance or performance of any
other covenants in the Indenture; or (iv) certain events involving bankruptcy,
insolvency or reorganization of the Company. The Indenture provides that the
Trustee may withhold notice to the holders of the Notes of any default (except
in payment of principal of, premium, if any, or interest with respect to the
Notes) if the Trustee considers it in the interest of the holders of the Notes
to do so.
 
     The Indenture provides that if an Event of Default shall have occurred and
be continuing, the Trustee or the holders of not less than 25% in aggregate
principal amount at maturity of the Notes then outstanding may declare the Issue
Price of the Notes, plus the accrued Original Issue Discount and accrued
interest on the Notes to the date of such declaration, to be due and payable
immediately. In the case of certain events of bankruptcy or insolvency, the
Issue Price of the Notes plus the Original Issue Discount accrued thereon and
interest on the Notes to the occurrence of such event shall automatically become
and be immediately due and payable. However, if the Company shall cure all
defaults (except the nonpayment of principal amount at maturity, accrued
Original Issue Discount and interest on any of the Notes which shall have become
due by acceleration) and certain other conditions are met, with certain
exceptions, such declaration may be canceled and past defaults may be waived by
the holders of a majority of the principal amount at maturity of the Notes then
outstanding.
 
     The holders of a majority in principal amount at maturity of the Notes then
outstanding shall have the right to direct the time, method and place of
conducting any proceedings for any remedy available to the Trustee, subject to
certain limitations specified in the Indenture.
 
MODIFICATION OF THE INDENTURE
 
     The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the holders of not less than a majority in principal amount
at maturity of the Notes at the time outstanding, to modify the Indenture or any
supplemental indenture or the rights of the holders of the Notes; provided,
however, no such modification may (i) extend the fixed maturity of any Note,
reduce the rate or extend the time for payment of interest thereon, change the
rate of accrual or extend the time of payment in connection with the Original
Issue Discount, reduce the principal amount at maturity, accrued Original Issue
Discount, Issue Price, Redemption Price, Fundamental Change Repurchase Price or
interest, if any, change the obligation of the Company to repurchase any Note
upon the happening of any Fundamental Change in a manner adverse to holders of
Notes, impair the right of a holder to institute suit for the payment thereof,
change the currency in which the Notes are payable, impair the right to convert
the Notes into Common Stock subject to the terms set forth in the Indenture, or
modify the provisions of the Indenture with respect to the subordination of the
Notes in a manner adverse to the holders of the Notes in any material respect,
without the consent of each holder of a Note so affected, or (ii) reduce the
aforesaid percentage of Notes whose holders are required to consent to any such
supplemental indenture, without the consent of the holders
 
                                      A-16
<PAGE>   87
 
of all of the Notes then outstanding. The Indenture also provides for certain
modifications of its terms without the consent of holders of the Notes for
certain specified purposes, including, among other things, curing ambiguities,
defects or inconsistencies, qualifying or maintaining the qualifications of the
Indenture under the Trust Indenture Act of 1939, as amended (the "TIA"), or
making any change that does not adversely affect the rights of any Noteholder.
 
INFORMATION CONCERNING THE TRUSTEE
 
     The Bank of New York, as the Trustee under the Indenture, has been
appointed by the Company as paying agent, conversion agent, registrar and
custodian with regard to the Notes. The Indenture provides that, except during
the continuance of an Event of Default, the Trustee thereunder will exercise
such rights and powers vested in it under the Indenture and use the same degree
of care and skill in its exercise as a prudent Person would exercise under the
circumstances in the conduct of such Person's own affairs.
 
     The Indenture and provisions of the TIA, incorporated by reference therein
contain limitations on the rights of the Trustee thereunder, should it become a
creditor of the Company, to obtain payment of certain claims in certain cases or
to realize on certain property received by it in respect of any such claims, as
security or otherwise. The Trustee is permitted to engage in other transactions;
provided, however, that it acquires any conflicting interest (within the meaning
of the TIA) it must eliminate such conflicting interest or resign.
 
LIMITATIONS OF CLAIMS IN BANKRUPTCY
 
     If a bankruptcy proceeding is commenced in respect of the Company, the
claim of a Holder of a Note is, under Title 11 of the United States Code,
limited to the Issue Price of the Note plus that portion of the Original Issue
Discount and unpaid interest that has accrued from the date of issue to the
commencement of the proceeding. In addition, the holders of the Notes will be
subordinated in right of payment to Senior Indebtedness and effectively
subordinated to the indebtedness and other obligations of the Company's
subsidiaries. See "Subordination of Notes" above.
 
GOVERNING LAW
 
     The Indenture and the Notes provide that they will be governed by the laws
of the State of New York, without regard to the principles of conflicts of law.
 
TAXATION OF NOTES
 
     See "Certain United States Federal Income Tax Considerations" for a
discussion of certain federal income tax matters
 
            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
 
UNITED STATES TAXATION OF UNITED STATES HOLDERS
 
     The following is a general discussion of certain material United States
federal income tax consequences of the purchase, ownership and disposition of
the Notes (and of Common Stock acquired upon a conversion of the Notes) to the
initial holders thereof. This discussion is based on provisions of the Internal
Revenue Code of 1986, as amended (the "Code"), Treasury regulations promulgated
thereunder, and administrative and judicial interpretations thereof now in
effect, all of which are subject to change, possibly with retroactive effect.
This discussion addresses the tax consequences to the initial holders of Notes
and does not address the tax consequences to subsequent holders of Notes.
Furthermore, this discussion is limited to holders who hold the Notes as capital
assets. This discussion is for general information only, and does not address
all of the tax consequences that may be relevant to particular holders in light
of their personal circumstances, or to certain types of holders (such as certain
financial institutions, insurance companies, tax exempt entities, dealers in
securities or persons who have hedged the interest rate).
 
                                      A-17
<PAGE>   88
 
     As used herein, the term "United States Holder" or "U.S. Holder" means a
holder of a Note, or of Common Stock acquired upon conversion of a Note, that is
for United States federal income tax purposes (i) a citizen or resident of the
United States, (ii) a corporation or partnership created or organized in or
under the laws of the United States or of any State, (iii) an estate the income
of which is subject to United States federal income taxation regardless of
source, or (iv) a trust which is subject to the supervision of a court within
the United States and the control of a United States fiduciary. As used herein,
the term "Foreign Holder" means a holder of a Note (or Common Stock acquired
upon conversion of a Note) who is not a United States Holder.
 
     PROSPECTIVE PURCHASERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO
THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE ACQUISITION, OWNERSHIP AND
DISPOSITION OF THE NOTES OR COMMON STOCK, INCLUDING THE APPLICABILITY OF ANY
FEDERAL ESTATE OR GIFT TAX LAWS OR ANY STATE, LOCAL OR FOREIGN TAX LAWS, CHANGES
IN APPLICABLE TAX LAWS AND ANY PENDING OR PROPOSED LEGISLATION.
 
     Tax Treatment of Interest Payments. Interest payments on the Notes will be
includable in a United States Holder's taxable income as received or accrued in
accordance with the holder's method of tax accounting.
 
     Original Issue Discount. The Notes are being issued at a substantial
discount from their principal amount at maturity. For federal income tax
purposes, the excess of the principal amount at maturity of a Note over its
issue price (generally the first price at which a substantial amount of the
Notes are sold) constitutes original issue discount ("OID"). The Notes will
carry a substantial amount of OID. U.S. Holders of the Notes will be required to
include OID in income periodically over the term of the Notes before receipt of
the cash attributable to such income. A U.S. Holder of a Note must include in
gross income for federal income tax purposes the sum of the daily portions of
OID with respect to the Note for each day during the taxable year or portion of
a taxable year on which such U.S. Holder holds the Note. The daily portion is
determined by allocating to each day of the accrual period a pro rata portion of
an amount equal to the adjusted issue price of the Note at the beginning of the
accrual period multiplied by the yield to maturity of the Note (determined by
compounding at the close of each accrual period and adjusted for the length of
the accrual period) reduced by any interest payable for such period. The accrual
period generally will be each six-month period (or shorter period from the date
of original issue) that ends on a day in the calendar year corresponding to the
maturity date of the Note or the date six months before such maturity date,
although a holder may elect another accrual period (with certain restrictions).
The adjusted issue price of the Note at the start of any accrual period is the
issue price of the Note increased by the accrued OID for each prior accrual
period. Under these rules, U.S. Holders will have to include in gross income
increasingly greater amounts of OID in each successive accrual period. A U.S.
Holder's original tax basis for determining gain or loss on the sale or other
disposition of a Note will be increased by any accrued OID includable in such
U.S. Holder's gross income.
 
     Sale, Exchange or Retirement of the Notes. Upon the sale, exchange,
redemption, retirement at maturity or other disposition of a Note, a United
States Holder generally will recognize capital gain or loss equal to the
difference between the amount of cash plus the fair market value of all property
received on such disposition (except to the extent such cash or property is
attributable to accrued interest, which is taxable as ordinary income) and such
holder's adjusted tax basis in the Note. Such gain or loss will be long-term
capital gain or loss if, at the time of such disposition, the United States
Holder's holding period in the Note is more than one year.
 
     Adjustments to Conversion Rate. The Conversion Rate of the Notes is subject
to adjustment under certain circumstances. See "Description of
Notes -- Conversion of Notes." Section 305 of the Code may treat a United States
Holder of Notes as receiving a constructive distribution, taxable as a dividend
to the extent of the Company's current or accumulated earnings and profits, in
the case of certain adjustments in the Conversion Rate of the Notes that may
occur in limited circumstances (particularly an adjustment to reflect a taxable
dividend to holders of the Common Stock).
 
                                      A-18
<PAGE>   89
 
     Conversion of Notes into Common Stock. Generally, no gain or loss will be
recognized for federal income tax purposes on a conversion of the Notes into
shares of Common Stock. However, cash paid in lieu of a fractional share of
Common Stock will result in capital gain (or loss) to the extent of the
difference between the amount of such cash and the portion of the adjusted basis
of the Note allocable to such fractional share. The adjusted basis of shares of
Common Stock received on conversion will equal the adjusted basis of the Note
converted, reduced by the portion of such adjusted basis allocated to any
fractional share of Common Stock deemed exchanged for cash. The holding period
of the Common Stock received on conversion will include the period during which
the converted Notes were held, except that the holding period of the Common
Stock allocable to accrued OID and accrued stated interest, if any, will not
include the holding period of the Notes converted. A United States Holder who
converts a Note into Common Stock between interest payment dates will be
required to include in income the OID accruing before the conversion, and will
be treated for United States federal income tax purposes as receiving a payment
of interest in an amount equal to the fair market value of the Common Stock
received for the payment of the accrued stated interest.
 
     Sale or Exchange of Common Stock. A United States Holder of Common Stock
into which the Notes have been converted generally will recognize capital gain
or loss upon the sale, exchange, redemption, or other disposition of the Common
Stock measured by the difference between the amount realized on such disposition
and the United States Holder's adjusted tax basis in the Common Stock. Such gain
or loss will be long-term capital gain or loss if the holding period of the
Common Stock (determined as described above under "Conversion of Notes into
Common Stock") is more than one year at the time of the sale or exchange.
Special rules may apply to certain redemptions of Common Stock which may result
in different treatment.
 
     Back-Up Withholding. A United States Holder of Notes or Common Stock may be
subject to "back-up withholding" at a rate of 31 percent with respect to certain
"reportable payments," including interest payments, dividend payments and, under
certain circumstances, principal payments on the Notes and payments of the
proceeds of the sale of Notes or Common Stock. These back-up withholding rules
apply if the United States Holder, among other things, (i) fails to furnish a
social security number or other taxpayer identification number ("TIN") certified
under penalties of perjury within a reasonable time after the request therefor,
(ii) furnishes an incorrect TIN, (iii) fails to report properly interest or
dividends, or (iv) under certain circumstances, fails to provide a certified
statement, signed under penalties of perjury, that the TIN furnished is the
correct number and that such holder is not subject to back-up withholding. A
United States Holder who does not provide the Company with its correct TIN also
may be subject to penalties imposed by the IRS. Any amount withheld from a
payment to a United States Holder under the back-up withholding rules is
creditable against the United States Holder's federal income tax liability,
provided the required information is furnished to the IRS. Back-up withholding
does not apply, however, with respect to payments made to certain holders,
including corporations, tax-exempt organizations and certain foreign persons,
provided their exemption from back-up withholding is properly established. The
Company will report to the holders of Notes and Common Stock and to the IRS the
amount of any "reportable payments" for each calendar year and the amount of tax
withheld, if any, with respect to such payments.
 
UNITED STATES TAXATION OF FOREIGN HOLDERS
 
     Taxation of Interest Payments and OID. Subject to the discussion of backup
withholding below, a Foreign Holder generally will not be subject to United
States federal income taxes or withholding on payments of interest or OID on a
Note, unless such Foreign Holder is (i) a direct or indirect 10 percent or
greater stockholder of the Company (taking into account certain stock ownership
attribution rules), (ii) a controlled foreign corporation related to the
Company, (iii) a bank which acquired the Notes on an extension of credit
pursuant to a loan agreement entered into in the ordinary course of its trade or
business or (iv) carrying on a trade or business within the United States with
which such amounts are effectively connected. To qualify for the exemption from
taxation, the Foreign Holder must provide a statement that (i) is signed by the
beneficial owner of the Note under penalties of perjury, (ii) certifies that
such owner is a Foreign Holder and (iii) provides the name and address of the
beneficial owner. The statement may be made on an IRS Form W-8 or a
substantially similar form. If a Note is held through a securities clearing
organization or certain financial institutions, the organization or institution
may provide a signed statement to the person
 
                                      A-19

otherwise required to withhold taxes. However, in such case, the signed
statement must be accompanied by a copy of the IRS Form W-8 or the substitute
form provided by the beneficial owner to the organization or institution.
 
     To the extent that such amounts are effectively connected with a U.S. trade
or business carried on by the Foreign Holder, the Foreign Holder will be subject
to regular U.S. income tax in the same manner as a U.S. resident. Effectively
connected income received by a Foreign Holder which is a corporation may be
subject to an additional "branch profits tax" at a rate of 30 percent (or such
lower rate as may be specified by an applicable treaty), subject to certain
adjustments.
 
     Dividends Paid on Common Stock. Dividends paid to a Foreign Holder of
Common Stock generally will be subject to withholding tax at a 30 percent rate
or such lower rate as may be specified by an applicable income tax treaty. For
purposes of determining whether tax is to be withheld at a 30 percent rate or at
a reduced rate as specified by an income tax treaty, under existing U.S.
Treasury Regulations the Company may presume that dividends paid to an address
in a foreign country are paid to a resident of such country absent definite
knowledge that such presumption is not warranted. However, under proposed U.S.
Treasury regulations which have not yet been put into effect, a Foreign Holder
of Common Stock who wishes to claim the benefits of an income tax treaty would
be required to certify as to its eligibility therefor.
 
     No withholding tax is imposed on dividends that are effectively connected
with the Foreign Holder's conduct of trade or business within the United States.
Instead, these effectively connected dividends are subject to regular U.S.
income tax in the same manner as if the Foreign Holder were a U.S. resident.
Effectively connected dividends received by a Foreign Holder which is a
corporation may be subject to an additional "branch profits tax" at a rate of 30
percent (or such lower rate as may be specified by an applicable treaty),
subject to certain adjustments.
 
     Sale, Exchange or Retirement of the Notes or Common Stock. A Foreign Holder
generally will not be subject to United States federal income tax (and generally
no tax will be withheld) with respect to gain realized on the sale, exchange,
redemption, retirement at maturity or other disposition of the Notes or Common
Stock, unless (i) the gain is effectively connected with a United States trade
or business conducted by the Foreign Holder, or (ii) the Foreign Holder is an
individual who is present in the United States for a period or periods
aggregating 183 or more days in the taxable year of the disposition and certain
other conditions are met. lf the gain is effectively connected with U.S. trade
or business, the gain would be subject to United States federal income tax at
applicable individual or corporate tax rates (and in the case of gain recognized
by a Foreign Holder which is a corporation, may be subject to an additional
"branch profits tax" at a rate of 30 percent or such lower rate as may be
specified by an applicable treaty, subject to certain adjustments). If the
Foreign Holder is an individual and is present in the United States for 183 days
or more in the taxable year of sale or other disposition and certain other
conditions are met (but the gain is not effectively connected with a U.S. trade
or business), the gain derived from the disposition of Notes or Common Stock
generally will be taxed at the rate of 30 percent (or lower treaty rate).
Foreign Holders should consult applicable income tax treaties, which may provide
for different rules.
 
     Federal Estate Taxes. Notes held at the time of death by an individual who
at the time of death is a Foreign Holder generally will not be included in such
Foreign Holder's gross estate for United States federal estate tax purposes
provided that interest paid with respect to such Notes would not be subject to
U.S. income tax under the rules described above in "Taxation of Interest
Payments and OID." Subject to an applicable estate tax treaty provision, Common
Stock held by a Foreign Holder at the time of death (or previously transferred
subject to certain retained rights or powers) will be included in the Foreign
Holder's gross estate for United States federal estate tax purposes.
 
     Certain FIRPTA Considerations. The foregoing discussion for Foreign Holders
assumes that the Company is not a United States real property holding
corporation ("USRPHC") within the meaning of Section 897(c) of the Code. In
general, if the Company were a USRPHC, Foreign Holders could be subject to
United States federal income tax on the sale, exchange, retirement or other
disposition of a Note and on the sale, exchange, or other disposition of Common
Stock. The Company believes that it is not a USRPHC.

     Back-up Withholding and Information Reporting on Payments of Proceeds of
Sales. Payment of the proceeds from the sale of Notes or Common Stock by or
through the foreign office of a foreign broker is not subject to back-up
withholding or information reporting. Information reporting (but not backup
withholding) will apply, however, to a payment by or through a foreign office of
a broker that is a United States person, that derives 50 percent or more of its
gross income for certain periods from the conduct of a trade or business in the
United States, or that is a "controlled foreign corporation" (generally. a
foreign corporation controlled by United States shareholders) with respect to
the United States, unless the broker has documentary evidence in its records
that the holder is a Foreign Holder and certain other conditions are met, or the
holder otherwise establishes an exemption. Payment by or through a United States
office of a broker is subject to both back-up withholding at a rate of 31
percent and information reporting unless the holder certifies under penalties of
perjury that it is a Foreign Holder or otherwise establishes an exemption. Any
amounts withheld under the back-up withholding rules would be creditable against
the holder's U.S. federal income tax liability or refunded to the holder,
provided the required information is filed with the IRS.

     The Notes Underwriting Agreement provides that the obligations of the
Underwriters to pay for and accept delivery of the Notes offered hereby are
subject to the approval of certain legal matters by their counsel and to certain
other conditions. Each Underwriter is obligated to take and pay for its
allocation of the Notes offered hereby (other than those covered by the
over-allotment described below) if any such Notes are taken.
 
     The Underwriters initially propose to offer the Notes to the public at the
public offering price set forth on the cover page hereof, plus accrued interest,
if any, from August   , 1997, and to certain dealers at such price less a
concession of      % of the principal amount of the Notes. After the initial
offering of the Notes, the public offering price and other selling terms may be
changed.
 
     The Company has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus, to purchase up to an aggregate of
$27,000,000 additional principal amount of Notes at the public offering price
set forth on the cover page hereof, less underwriting discounts and commissions.
The Underwriters may exercise such option solely for the purpose of covering
over-allotments, if any, made in connection with the offering of the Notes
offered hereby. To the extent such option is exercised, each Underwriter will
become obligated, subject to certain conditions, to purchase approximately the
same percentage of such additional Notes as the number set forth next to such
Underwriter's name in the preceding table bears to the total aggregate principal
amount of Notes set forth next to the names of all Underwriters in the preceding
table.
 
     Each of the Company, the directors and executive officers of the Company
and the Selling Stockholders has agreed that, without the prior written consent
of Morgan Stanley & Co. Incorporated on behalf of the Underwriters, it will not,
during the period ending 90 days (45 days in the case of the directors and
executive officers) after the date of this Prospectus, (i) offer, sell, contract
to sell, sell any option or contract to purchase, purchase any option or
contract to sell, grant any option, right or warrant to purchase, loan or
otherwise dispose of, directly or indirectly, any shares of Common Stock or any
securities convertible into or exercisable or exchangeable for Common Stock, or
(ii) enter into any swap or other arrangement that transfers, in whole or in
part, any of the economic consequences of ownership of the Common Stock, whether
any such transaction is described in clause (i) or (ii) above is settled by
delivery of Common Stock or such other securities, in cash or otherwise. The
restriction on the Company is subject to exceptions for the issuance of Common
Stock pursuant to existing director and employee benefit plans and as payment
for acquisitions by the Company. The restrictions on the officers, directors and
Selling Stockholders is subject to exceptions for charitable contributions and
estate planning so long as the recipient or donee is subject to a similar
restricted transfer period.

     Application will be made to list the Notes on the Nasdaq National Market.
The Underwriters have advised the Company that they presently intend to make a
market in the Notes as permitted by applicable laws and regulations. The
Underwriters are not obligated, however, to make a market in the Notes and any
such market making may be discontinued at any time at the sole discretion of the
Underwriters. Accordingly, no assurance can be given as to the liquidity of, or
trading markets for, the Notes.
 
     In order to facilitate the offering of the Notes, the Underwriters may
engage in transactions that stabilize, maintain or otherwise affect the price of
the Notes or the Common Stock. Specifically, the Underwriters may over-allot in
connection with the offering, creating a short position in the Notes for their
own account. In addition, to cover over-allotments or to stabilize the price of
the Notes, the Underwriters may bid for, and purchase, the Notes or shares of
the Common Stock in the open market. Any of these activities may stabilize or
maintain the market price of the Notes or the Common Stock above independent
market levels. The Underwriters are not required to engage in these activities,
and may end any of these activities at any time. The Underwriters and dealers
may engage in passive market making transactions in the Common Stock in
accordance with Rule 103 of Regulation M promulgated by the Securities and
Exchange Commission. In general, a passive market maker may not bid for, or
purchase, the Common Stock at a price that exceeds the highest independent bid.
In addition, the net daily purchases made by any passive market maker generally
may not exceed 30% of its average daily trading volume in the Common Stock
during a specified two month prior period, or 200 shares, whichever is greater.
A passive market maker must identify passive market making bids as such on the
NASDAQ electronic inter-dealer reporting system. Passive market making may
stabilize or maintain the market price of the Common Stock above independent
market levels. Underwriters and dealers are not required to engage in passive
market making and may end passive market making activities at any time.
 
     The Underwriting Agreement provides that the Company will indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act.
 
     The Underwriters have engaged in transactions with and performed various
investment banking and other services for the Company in the past, and may do so
from time to time in the future.
 
     The Company has provided staffing services to Morgan Stanley & Co.
Incorporated in the past, and may continue to do so in the future.
 
                                 LEGAL MATTERS
 
     The validity of the Notes offered hereby will be passed upon for the
Company by Vinson & Elkins L.L.P., Houston, Texas. Certain legal matters will be
passed upon for the Underwriters by Andrews & Kurth L.L.P., Houston, Texas.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Certificate of Incorporation of the Company limits the liability of the
directors of the Company to the Company or its stockholders (in their capacity
as directors but not in their capacity as officers) to the fullest extent
permitted by the DGCL. Accordingly, pursuant to the terms of the DGCL as
presently in effect, directors of the Company will not be personally liable for
monetary damages for breach of a director's fiduciary duty as a director, except
for liability (i) for any breach of the director's duty of loyalty to the
Company or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) for
unlawful payments of dividends or unlawful stock repurchases or redemptions as
provided in Section 174 of the DGCL, or (iv) for any transaction from which the
director derived an improper personal benefit. In addition, such provisions do
not limit the rights of the Company or its stockholders, in appropriate
circumstances, to seek equitable remedies such as injunctive or other forms of
non-monetary relief. Such remedies may not be effective in all cases. The
Certificate of Incorporation also provides that if the DGCL is amended after the
approval of the Certificate of Incorporation to authorize corporate action
further eliminating or limiting the personal liability of the directors, then
the liability of a director of the Company will be eliminated or limited to the
full extent permitted by the DGCL, as so amended. In addition, the Certificate
of Incorporation provides that the Company may purchase and maintain insurance
on behalf of any director, officer, employee or agent of the Company who is or
was serving, at the request of the Corporation, as a director, officer,
employer, or agent for another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him and incurred by him
in such capacity or arising out of his status as such, whether or not the
Company would have the power to indemnify such person for such liability under
the DGCL.
 
     In addition, the Bylaws, in substance, require the Company to indemnify
each person who is or was a director, officer, employee or agent of the Company
to the full extent permitted by the laws of the State of Delaware in the event
he is involved in legal proceedings by reason of the fact that he is or was a
director, officer, employee or agent of the Company, or is or was serving at the
Company's request as a director, officer, employee or agent of another
corporation, partnership or other enterprise. The Company is also required to
advance to such persons payments incurred in defending a proceeding to which
indemnification might apply, provided the recipient provides an undertaking
agreeing to repay all such advanced amounts if it is ultimately
 
                                      II-1
<PAGE>   95
 
determined that he is not entitled to be indemnified. In addition, the Bylaws
specifically provide that the indemnification rights granted thereunder are
non-exclusive.
 
     Each director of the Company has also entered into an indemnification
agreement with the Company (the "Indemnification Agreements"). The
Indemnification Agreements are intended to permit indemnification which may be
broader than specifically provided by law. It is possible that the applicable
law could change the degree to which indemnification is expressly permitted.
 
     The Indemnification Agreements cover most monetary liabilities paid in
settlement of claims if such settlement is approved in advance by the Company,
which approval shall not be unreasonably withheld. The Indemnification
Agreements generally cover claims relating to the fact that the indemnified
party is or was an agent ("Agent") of the Company or its subsidiary, or is or
was serving at the request of the Company as an Agent for another entity. The
Indemnification Agreements also obligate the Company to promptly advance all
expenses incurred in connection with any claim. The indemnitee is, in turn,
obligated to reimburse the Company for all amounts so advanced if it is later
determined that the indemnitee is not entitled to indemnification. The
indemnification provided under the Indemnification Agreements is not exclusive
of any other indemnity rights; however, double payment to the indemnitee is
prohibited.
 
     The Company is not obligated to indemnify the indemnitee with respect to
(a) acts, omissions, or transactions from which the indemnitee may not be
relieved of liability under applicable law, (b) claims initiated or brought
voluntarily by the indemnitee which are not defensive, except in certain
situations, (c) proceedings instituted by the indemnitee to enforce the
Indemnification Agreements which are not made in good faith or are frivolous, or
(d) violations of Section 16(b) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act") or any similar successor statute.

ITEM 17. UNDERTAKINGS.
 
     (a) The undersigned registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this registration statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement
 
                                      II-2
<PAGE>   96
 
     relating to the securities offered therein, and the offering of such
     securities at that time shall be deemed to be the initial bona fide
     offering thereof.
 
     (b) The registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the registrant's annual
report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and,
where applicable, each filing of an employee benefits plan's annual report
pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference
in this registration statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.
 
     (c) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to any charter provision, by-law, contract, arrangement,
statute, or otherwise, the registrant has been advised that in the opinion of
the Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such labilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question of whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

Dear Sirs and Mesdames:

                  Certain shareholders of the Company (the "SELLING
SHAREHOLDERS") of CORESTAFF, Inc., a Delaware corporation (the "COMPANY"),
named in Schedule III hereto severally propose to sell to the several
Underwriters named in Schedule I and II hereto (the "UNDERWRITERS"), an
aggregate of 6,000,000 shares of the Common Stock, par value $.01 per share, of
the Company (the "FIRM SHARES"), each Selling Shareholder selling the amount
set forth opposite such Selling Shareholder's name in Schedule III hereto.

                  It is understood that, subject to the conditions hereinafter
stated, 5,000,000 Firm Shares (the "U.S. FIRM SHARES") will be sold to the
several U.S. Underwriters named in Schedule I hereto (the "U.S. UNDERWRITERS")
in connection with the offering and sale of such U.S. Firm Shares in the United
States and Canada to United States and Canadian Persons (as such terms are
defined in the Agreement Between U.S. and International Underwriters of even
date herewith), and 1,000,000 Firm Shares (the "INTERNATIONAL SHARES") will be
sold to the several International Underwriters named in Schedule II hereto (the
"INTERNATIONAL UNDERWRITERS") in connection with the offering and sale of such
International Shares outside the United States and Canada to persons

other than United States and Canadian Persons. Morgan Stanley & Co.
Incorporated and Goldman, Sachs & Co., Alex. Brown & Sons, Donaldson, Lufkin &
Jenrette Securities Corporation, Montgomery Securities and The
Robinson-Humphrey Company, Inc. shall act as representatives (the "U.S.
REPRESENTATIVES") of the several U.S. Underwriters, and Morgan Stanley & Co.
International Limited and Goldman Sachs International shall act as
representatives (the "INTERNATIONAL REPRESENTATIVES") of the several
International Underwriters. The U.S. Underwriters and the International
Underwriters are hereinafter collectively referred to as the Underwriters.

                  The additional Selling Stockholder specified in Schedule III
hereto also proposes to issue and sell to the several U.S. Underwriters not
more than an additional 900,000 shares of its Common Stock, par value $.01 per
share, (the "ADDITIONAL SHARES") if and to the extent that the U.S.
Representatives shall have determined to exercise, on behalf of the U.S.
Underwriters, the right to purchase such shares of common stock granted to the
U.S. Underwriters in Section 2 hereof. The Firm Shares and the Additional
Shares are hereinafter collectively referred to as the "SHARES." The shares of
Common Stock, par value $.01 per share, of the Company to be outstanding after
giving effect to the sales contemplated hereby are hereinafter referred to as
the "COMMON STOCK."

                  The Company has filed with the Securities and Exchange
Commission (the "COMMISSION") a registration statement relating to the Shares.
The registration statement contains two prospectuses to be used in connection
with the offering and sale of the Shares: the U.S. prospectus, to be used in
connection with the offering and sale of Shares in the United States and Canada
to United States and Canadian Persons, and the international prospectus, to be
used in connection with the offering and sale of Shares outside the United
States and Canada to persons other than United States and Canadian Persons. The
international prospectus is identical to the U.S. prospectus except for the
outside front cover page. The registration statement as amended at the time it
becomes effective, including the information (if any) deemed to be part of the
registration statement at the time of effectiveness pursuant to Rule 430A under
the Securities Act of 1933, as amended (the "SECURITIES ACT"), is hereinafter
referred to as the "Registration Statement"; the U.S. prospectus and the
international prospectus in the respective forms first used to confirm sales of
Shares are hereinafter collectively referred to as the "PROSPECTUS" (including,
in the case of all references to the Registration Statement or the Prospectus,
documents incorporated therein by reference). The terms "supplement" and
"amendment" or "amend" as used in this Agreement with respect to the
Registration Statement or Prospectus shall include all documents subsequently
filed by the Company with the Commission pursuant to the Securities Exchange
Act of 1934, as amended (the "EXCHANGE ACT"), that are deemed to be
incorporated by reference in the Prospectus. If the Company has filed an
abbreviated registration statement to register additional shares of Common
Stock pursuant to Rule 462(b) under the Securities Act (the "RULE 462
REGISTRATION STATEMENT"), then any reference herein to the term "REGISTRATION
STATEMENT" shall be deemed to include such Rule 462 Registration Statement.

         order suspending the effectiveness of the Registration Statement is in
         effect, and no proceedings for such purpose are pending before or
         threatened by the Commission.

                  (b) (i) Each document, if any, filed or to be filed pursuant
         to the Exchange Act and incorporated by reference in the Prospectus
         complied or will comply when so filed in all material respects with
         the Exchange Act and the applicable rules and regulations of the
         Commission thereunder, (ii) the Registration Statement, when it became
         effective, did not contain and, as amended or supplemented, if

         or omit to state a material fact required to be stated therein or
         necessary to make the statements therein not misleading, (iii) the
         Registration Statement and the Prospectus comply and, as amended or
         supplemented, if applicable, will comply in all material respects with
         the Securities Act and the applicable rules and regulations of the
         Commission thereunder and (iv) the Prospectus does not contain and, as
         amended or supplemented, if applicable, will not contain any untrue

         circumstances under which they were made, not misleading, except that
         the representations and warranties set forth in this paragraph 1(b) do
         not apply to statements or omissions in the Registration Statement or
         the Prospectus based upon information relating to any Underwriter

         and to conduct its business as described in the Prospectus and is duly
         qualified to transact business and is in good standing in each

         have a material adverse effect on the Company and its subsidiaries,
         taken as a whole.

                  (d) Each subsidiary of the Company has been duly
         incorporated, is validly existing as a corporation in good standing

         transact business and is in good standing in each jurisdiction in
         which the conduct of its business or its ownership or leasing of
         property requires such qualification, except to the extent that the
         failure to be so qualified or be in good standing would not have a
         material adverse effect on the Company and its subsidiaries, taken as
         a whole; all of the issued shares of capital stock of each subsidiary
         of the Company have been duly and validly authorized and issued, are
         fully paid and non-assessable and (except for directors' qualifying

                  (g) The Shares of Common Stock have been duly authorized and
         are validly issued, fully paid and non-assessable, and the issuance of
         such Shares did not violate any preemptive or similar rights.

                  (h) The execution and delivery by the Company of, and the
         performance by the Company of its obligations under, this Agreement
         will not contravene any provision of applicable law or the Certificate
         of Incorporation or By-laws of the Company or any agreement or other
         instrument binding upon the Company or any of its subsidiaries that is
         material to the Company and its subsidiaries, taken as a whole, or any
         judgment, order or decree of any governmental body, agency or court
         having jurisdiction over the Company or any subsidiary, and no
         consent, approval, authorization or order of, or qualification with,
         any governmental body or agency is required for the performance by the
         Company of its obligations under this Agreement, except such as may be
         required by the securities or Blue Sky laws of the various states in
         connection with the offer and sale of the Shares.

                  (i) There has not occurred any material adverse change, or
         any development involving a prospective material adverse change, in
         the condition, financial or otherwise, or in the earnings, business or
         operations of the Company and its subsidiaries, taken as a whole, from

         supplements thereto subsequent to the date of this Agreement).

                  (j) There are no legal or governmental proceedings pending
         or, to the Company's knowledge after due inquiry, threatened to which
         the Company or any of its subsidiaries is a party or to which any of
         the properties of the Company or any of its subsidiaries is subject
         that are required to be described in the Registration Statement or the
         Prospectus and are not so described or any statutes, regulations,
         contracts or other documents that are required to be described in the
         Registration Statement or the Prospectus or to be filed as exhibits to
         the Registration Statement that are not described or filed as
         required.

                  (k) Each preliminary prospectus filed as part of the
         registration statement as originally filed or as part of any amendment
         thereto, or filed pursuant to Rule 424 under the Securities Act,
         complied when so filed in all material respects with the Securities
         Act and the applicable rules and regulations of the Commission

                  (l) The Company is not and, after giving effect to the
         offering and sale of the Shares and the application of the proceeds
         thereof as described in the Prospectus, will not be an "investment
         company" as such term is defined in the Investment Company Act of
         1940, as amended.

                  (m) The Company and its subsidiaries (i) are in compliance
         with any and all applicable foreign, federal, state and local laws and

         contaminants ("ENVIRONMENTAL LAWS"), (ii) have received all permits,
         licenses or other approvals required of them under applicable
         Environmental Laws to conduct their respective businesses and (iii)
         are in compliance with all terms and conditions of any such permit,
         license or approval, except where such noncompliance with
         Environmental Laws, failure to receive required permits, licenses or
         other approvals or failure to comply with the terms and conditions of
         such permits, licenses or approvals would not, singly or in the
         aggregate, have a material adverse effect on the Company and its
         subsidiaries, taken as a whole.

                  (n) There are no costs or liabilities associated with
         Environmental Laws (including, without limitation, any capital or
         operating expenditures required for clean-up, closure of properties or
         compliance with Environmental Laws or any permit, license or approval,
         any related constraints on operating activities and any potential
         liabilities to third parties) which would, singly or in the aggregate,
         have a material adverse effect on the Company and its subsidiaries,
         taken as a whole.

                  (o) There are no contracts, agreements or understandings
         between the Company and any person granting such person the right to
         require the Company to file a registration statement under the
         Securities Act with respect to any securities of the Company or to
         require the Company to include such securities with the Shares
         registered pursuant to the Registration Statement, except for rights
         under such contracts or agreements that have been waived by all
         persons holding such rights.

                  (p) The Company has complied with all provisions of Section
         517.075, Florida Statutes relating to doing business with the
         Government of Cuba or with any person or affiliate located in Cuba.

                  (q) Neither the Company nor any of its subsidiaries is in
         violation of its Certificate of Incorporation or By-laws or in default
         in the performance or observance of any material obligation,
         agreement, covenant or condition contained in any indenture, mortgage,
         deed of trust, loan agreement, lease or other agreement or instrument
         to which it is a party or by which it or any of its properties may be
         bound.

         caption "Description of Capital Stock," insofar as they purport to

         and know-how necessary to conduct the business now or proposed to be
         conducted by the Company as described in the Prospectus, and, except
         as disclosed in the Prospectus, the Company has not received any
         notice of infringement of or conflict with (and knows of no such
         infringement of or conflict with) asserted rights of others with

                  the summary of this Agreement and Exhibit A hereto,
                  "Underwriters" and (B) in the Registration Statement in Item
                  15, in each case insofar as such statements constitute
                  summaries of the legal matters, documents or proceedings
                  referred to therein, fairly present the information called
                  for with respect to such legal matters, documents and

                  the Registration Statement or the Prospectus and are not so
                  described or of any statutes, regulations, contracts or other
                  documents that are required to be described in the
                  Registration Statement or the Prospectus or to be filed as
                  exhibits to the Registration Statement that are not described
                  or filed as required;

                           (xi) the Company is not and, after giving effect to
                  the offering and sale of the Shares and the application of
                  the proceeds thereof as described in the Prospectus, will not
                  be an "investment company" as such term is defined in the

                           (xii) except as described in the Prospectus or as
                  have been waived at the Closing Date, there are no persons
                  with registration or similar rights to have any securities of
                  the Company registered pursuant to the Registration Statement
                  or otherwise registered by the Company under the Securities
                  Act or the Exchange Act pursuant to any agreement or
                  instrument known to us after due inquiry to which the Company
                  is a party; and

                           (xiii) such counsel (A) is of the opinion that each
                  document, if any, filed pursuant to the Exchange Act and
                  incorporated by reference in the Prospectus (except for
                  financial statements and schedules as to which such counsel
                  need not express any opinion) complied when so filed as to
                  form in all material respects with the Exchange Act and the
                  rules and regulations of the Commission thereunder, (B) is of
                  the opinion that the Registration Statement and Prospectus
                  (except for financial statements and schedules and other
                  financial and statistical data included therein as to which
                  such counsel need not express any opinion) comply as to form
                  in all material respects with the Securities Act and the
                  applicable rules and regulations of the Commission
                  thereunder, (C) has no reason to believe that (except for
                  financial statements and schedules and other financial and
                  statistical data as to which such counsel need not express
                  any belief) the Registration Statement and the prospectus
                  included therein at the time the Registration Statement
                  became effective contained any untrue statement of a material
                  fact or omitted to state a material fact required to be
                  stated therein or necessary to make the statements therein
                  not misleading and (D) has no reason to believe that (except
                  for financial statements and schedules and other financial
                  and statistical data as to which such counsel need not
                  express any belief) the Prospectus contains any untrue
                  statement of a material fact or omits to state a material
                  fact necessary in order to make the statements therein, in
                  the light of the circumstances under which they were made,
                  not misleading.

                  (d) The Underwriters shall have received on the Closing Date
         an opinion of each of (A) Kirkland & Ellis, (B) Kennedy Covington
         Lobdell & Hickman, L.L.P., and (C) Vinson & Elkins, L.L.P., counsel
         for (A) Golder, Thoma, Cressey Fund III Limited

                  any agreement or other instrument binding upon such Selling

                  judgment, order or decree of any governmental body, agency or
                  court having jurisdiction over such Selling Shareholder
                  (excluding breaches, violations and defaults that,
                  individually or in the aggregate, will not materially

                  Shares;

                           (v) such Selling Shareholder has valid title to the
                  Shares to be sold by such Selling Shareholder and the legal
                  right and power, and all authorization and approval required
                  by law, to enter into this Agreement and the Custody
                  Agreement and Power of Attorney of such Selling Shareholder

                  of the Shares to be sold by such Selling Shareholder under
                  this Agreement; upon delivery of the Shares to be sold by the
                  Selling Shareholders under this Agreement and payment of the
                  purchase price therefor as contemplated by this Agreement,
                  assuming the Underwriters have purchased the Shares for value
                  in good faith and without notice of any adverse claim or
                  actual knowledge of a restriction on transfer, (1) the
                  Underwriters will have acquired all rights of such Selling
                  Shareholder in such Shares free of any adverse claim, any
                  lien in favor of the Company and any restrictions on transfer
                  imposed by the Company, and (2) the owner of such Shares, if
                  other than such Selling Shareholder, is precluded from
                  asserting against the Underwriters the ineffectiveness of any
                  unauthorized endorsement or instruction; and

                  (e) The Underwriters shall have received on the Closing Date
         an opinion of Andrews & Kurth L.L.P., counsel for the Underwriters,
         dated the Closing Date, covering the matters referred to in Sections
         5(c)(vi), 5(c)(vii), 5(c)(ix) (but without limitation to
         "Underwriters") and 5(c)(xiii)(B)-(D) above.

                  With respect to subparagraph (xiii) of paragraph (c) above,
         Vinson & Elkins, L.L.P. and Andrews & Kurth L.L.P., may state that
         their opinion and belief are based upon their participation and
         preparation of the Registration Statement and Prospectus and any
         amendments or supplements thereto and review and discussion of the
         contents thereof, but are without independent check or verification,
         except as specified.

                  The opinions of Vinson & Elkins, L.L.P. on behalf of the
         Company, and Kirkland & Ellis, Kennedy Covington Lobdell & Hickman,
         L.L.P. and Vinson & Elkins, L.L.P. on behalf of the Selling
         Shareholder described in paragraphs (c) and (d) above, shall be
         rendered to the Underwriters at the request of the Company or one or
         more of the Selling Shareholders, as the case may be, and shall so
         state therein.

                  (f) The Underwriters shall have received, on each of the date
         hereof and the Closing Date, a letter dated the date hereof or the
         Closing Date, as the case may be, in form and substance satisfactory
         to the Underwriters, from Ernst & Young LLP, independent public
         accountants, containing statements and information of the type
         ordinarily included in accountants' "comfort letters" to underwriters
         with respect to the financial statements and certain financial
         information contained in, or incorporated by reference into, the
         Registration Statement and the Prospectus; provided that the letter
         delivered on the Closing Date shall use a "cut-off date" not earlier
         than the date hereof.

                  (g) The "lock-up" agreements, each substantially in the form
         of Exhibit A hereto, between you and certain shareholders, officers
         and directors of the Company (other than the Selling Shareholders)
         relating to sales and certain other dispositions of shares of Common
         Stock or certain other securities, delivered to you on or before the
         date hereof, shall be in full force and effect on the Closing Date.

         been duly approved, subject to notice of issuance, for quotation on
         the Nasdaq National Market.

                  (i) The several obligations of the U.S. Underwriters to
         purchase Additional Shares hereunder are subject to the delivery to
         the U.S. Representatives on the Option Closing Date of such documents
         as they may reasonably request with respect to the good standing of
         the Company, the due authorization and issuance of the Additional
         Shares and other matters related to the issuance of the Additional
         Shares.

                  7.       COVENANTS OF THE COMPANY.  In further consideration
of the agreements of the Underwriters herein contained, the Company covenants 
with each Underwriter as follows:

                  (a) To furnish to you, without charge, 13 signed copies of
         the Registration Statement (including exhibits thereto and any
         documents incorporated therein by reference) and for delivery to each
         other Underwriter a conformed copy of the Registration Statement
         (without exhibits thereto but including documents incorporated therein
         by reference) and to furnish to you in New York City, without charge,
         prior to 10:00 A.M. New York City time on the business day next
         succeeding the date of this Agreement and during the period mentioned
         in paragraph (c) below, as many copies of the Prospectus, any
         documents incorporated therein by reference and any supplements and
         amendments thereto or to the Registration Statement as you may
         reasonably request.

                  (b) Before amending or supplementing the Registration
         Statement or the Prospectus, to furnish to you a copy of each such
         proposed amendment or supplement and not to file any such proposed
         amendment or supplement to which you reasonably object, and to file
         with the Commission within the applicable period specified in Rule
         424(b) under the Securities Act any prospectus required to be filed
         pursuant to such Rule.

                  (c) If, during such period after the first date of the public
         offering of the Shares as in the opinion of counsel for the
         Underwriters the Prospectus is required by law to be delivered in
         connection with sales by an Underwriter or dealer, any event shall
         occur or condition exist as a result of which it is necessary to amend
         or supplement the Prospectus in order to make the statements therein,
         in the light of the circumstances when the Prospectus is delivered to
         a purchaser, not misleading, or if, in the opinion of counsel for the
         Underwriters, it is necessary to amend or supplement the Prospectus to
         comply with applicable law, forthwith to prepare, file with the
         Commission and furnish, at its own expense, to the Underwriters and to
         the dealers (whose names and addresses you will furnish to the
         Company) to which Shares may have been sold by you on behalf of the
         Underwriters and to any other dealers upon request, either amendments
         or supplements to the Prospectus so that the statements in the
         Prospectus as so amended or supplemented will not, in the light of the
         circumstances when the Prospectus is delivered to a purchaser, be
         misleading or so that the Prospectus, as amended or supplemented, will
         comply with law.

         the rules and regulations of the Commission thereunder.

statement or alleged untrue statement of a material fact contained in the
Registration Statement or any amendment thereof, any preliminary prospectus or
the Prospectus (as amended or supplemented if the Company shall have furnished
any amendments or supplements thereto), or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages or liabilities are caused by any such untrue statement
or omission or alleged untrue statement or omission based upon information
relating to any Underwriter furnished to the Company in writing by such
Underwriter through you expressly for use therein. Notwithstanding the
foregoing, in no event shall any Inside Seller be required to pay an amount in
indemnification under this Section 9(a) in excess of the total price at which
Shares sold by such Inside Seller were offered to the public.

                  (b) The Selling Shareholders other than the Insider Seller
(the "OTHER SELLERS"), agree to indemnify and hold harmless each Underwriter
and each person, if any, who controls any Underwriter within the meaning of
either Section 15 of the Securities Act or Section 20 of the Exchange Act, from
and against any and all losses, claims, damages and liabilities (including,
without limitation, any legal or other expenses reasonably incurred in
connection with defending or investigating any such action or claim) caused by
any untrue statement or alleged untrue statement of a material fact contained
in the Registration Statement or any amendment thereof, any preliminary
prospectus or the Prospectus (as amended or supplemented if the Company shall
have furnished any amendments or supplements thereto), or caused by any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, in
each case to the extent, but only to the extent, that such untrue statement or
alleged untrue statement or omission or alleged omission was made in any
Preliminary Prospectus, the Registration Statement or the Prospectus or any
such amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by such Other Seller expressly for use
therein, except insofar as such losses, claims, damages or liabilities are
caused by any such untrue statement or omission or alleged untrue statement or
omission based upon information relating to any Underwriter any in writing by
such Underwriter through you expressly for use therein; provided, however, that
each Other Seller shall not be liable to any Underwriter under the indemnity
agreement in this subsection (b) with respect to any Preliminary Prospectus to
the extent that any such loss, claim, damage or liability to any Underwriter
results from the fact that such


                                       19

<PAGE>   21



Underwriter sold Shares to a person as to whom it shall be established that
there was not sent or given, at or prior to the written confirmation of such
sale, a copy of the Prospectus or of the Prospectus as then amended or
supplemented in any case where such delivery is required by the Securities Act
if the Company has previously furnished copies thereof in sufficient quantity
to such Underwriter and the loss, claim, damage or liability of such
Underwriter results from an untrue statement or omission of a material fact
contained in the Preliminary Prospectus which was identified in writing at such
time to such Underwriter and corrected in the Prospectus or in the Prospectus
as then amended or supplemented. Notwithstanding the foregoing, in no event
shall any Other Seller be required to pay an amount in indemnification under
this Section 9(b) or contribution under Section 9(e) hereof in excess of the
net amount received by such Other Seller from the sale of the Shares pursuant
to the Prospectus.

                  (c) Each Selling Shareholder agrees, severally and not
jointly, to indemnify and hold less the Company, its directors, its officers
who sign the Registration Statement and each son, if any, who controls the
Company within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act, from and against any and all losses, claims,
damages and liabilities (including, without limitation, any legal or other
expenses reasonably incurred in connection with defending or investigating any
such action or claim) caused by any untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement or any
amendment thereof, any preliminary prospectus or the Prospectus (as amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto), or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, but only with reference to information relating to such
Selling Shareholder furnished in writing by or on behalf of such Selling
Shareholder expressly for use in the Registration Statement, any preliminary
prospectus, the Prospectus or any amendments or supplements thereto.

                  (d) Each Underwriter agrees, severally and not jointly, to
indemnify and hold harmless the Company, the Selling Shareholders, the
directors of the Company, the officers of the Company who sign the Registration
Statement and each person, if any, who controls the Company or any Selling
Shareholder within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act from and against any and all losses, claims,
damages and liabilities (including, without limitation, any legal or other
expenses reasonably incurred in connection with defending or investigating any
such action or claim) caused by any untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement or any
amendment thereof, any preliminary prospectus or the Prospectus (as amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto), or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, but only with reference to information relating to such
Underwriter furnished to the Company in writing by such Underwriter through you
expressly for use in the Registration Statement, any preliminary prospectus,
the Prospectus or any amendments or supplements thereto.

                  (e) In case any proceeding (including any governmental
investigation) shall be instituted involving any person in respect of which
indemnity may be sought pursuant to paragraph (a), (b), (c) or (d) of this
Section 9, such person (the "INDEMNIFIED PARTY") shall promptly notify the
person against whom such indemnity may be sought (the "INDEMNIFYING PARTY") in
writing and the indemnifying party, upon request of the indemnified party,
shall retain counsel reasonably satisfactory to the indemnified party to
represent the indemnified party and any others the indemnifying party may
designate in such proceeding and shall pay the fees and disbursements of such
counsel related to such proceeding. In any such proceeding, any indemnified
party shall have the right to retain its own counsel, but the fees and expenses
of such counsel shall be at the expense of such indemnified party unless (i)
the indemnifying party and the indemnified party shall have mutually agreed to
the retention of such counsel or (ii) the named parties to any such proceeding
(including any impleaded parties) include both the indemnifying party and the
indemnified party and representation of both parties by the same counsel would
be inappropriate due to actual or potential differing interests between them.
It is understood that the indemnifying party shall not, in respect of the legal
expenses of any indemnified party in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for (i) the fees and expenses
of more than one separate firm (in addition to any local counsel) for all
Underwriters and all persons, if any, who control any Underwriter within the
meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act, (ii) the fees and expenses of more than one separate firm (in
addition to any local counsel) for the Company, its directors, its officers who
sign the Registration Statement and each person, if any, who controls the
Company within the meaning of either such Section and (iii) the fees and
expenses of more than one separate firm (in addition to any local counsel) for
all Selling Shareholders and all persons, if any, who control any Selling
Shareholder within the meaning of either such Section, and that all such fees
and expenses shall be reimbursed as they are incurred. In the case of any such
separate firm for the Underwriters and such control persons of any
Underwriters, such firm shall be designated in writing by Morgan Stanley & Co.
Incorporated. In the case of any such separate firm for the Company, and such
directors, officers and control persons of the Company, such firm shall be
designated in writing by the Company. In the case of any such separate firm for
the Selling Shareholders and such control persons of any Selling Shareholders,
such firm shall be designated in writing by the persons named as
attorneys-in-fact for the Selling Shareholders under the Powers of Attorney.
The indemnifying party shall not be liable for any settlement of any proceeding
effected without its written consent, but if settled with such consent or if
there be a final judgment for the plaintiff, the indemnifying party agrees to
indemnity the indemnified party from and against any loss or liability by
reason of such settlement or judgment. Notwithstanding the foregoing sentence,
if at any time an indemnified party shall have requested an indemnifying party
to reimburse the indemnified party for fees and expenses of counsel as
contemplated by the second and third sentences of this paragraph, the
indemnifying party agrees that it shall be liable for any settlement of any
proceeding effected without its written consent if (i) such settlement is
entered into more than 30 days after receipt by such indemnifying party of the
aforesaid request and (ii) such indemnifying party shall not have reimbursed
the indemnified party in accordance with such request prior to the date of such
settlement. No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement of any pending or threatened
proceeding in respect of which any indemnified party is or could have been a
party and


                                       21

<PAGE>   23



indemnity could have been sought hereunder by such indemnified party, unless
such settlement includes an unconditional release of such indemnified party
from all liability on claims that are the subject matter of such proceeding.

                  (f) To the extent the indemnification provided for in
paragraph (a), (b), (c) or (d) of this Section 9 is unavailable to an
indemnified party or insufficient in respect of any losses, claims, damages or
liabilities referred to therein, then each indemnifying party under such
paragraph, in lieu of indemnifying such indemnified party thereunder, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities (i) in such proportion as is
appropriate to reflect the relative benefits received by the indemnifying party
or parties on the one hand and the indemnified party or parties on the other
hand from the offering of the Shares or (ii) if the allocation provided by
clause (i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the indemnifying party or parties on the
one hand and of the indemnified party or parties on the other hand in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative benefits received by the Company or the Selling
Shareholders on the one hand and the Underwriters on the other hand in
connection with the offering of the Shares shall be deemed to be in the same
respective proportions as the net proceeds from the offering of the Shares
(before deducting expenses) received by each Selling Stockholder and the total
underwriting discounts and commissions received by the Underwriters, in each
case as set forth in the table on the cover of the Prospectus, bear to the
aggregate Public Offering Price of the Shares. The relative fault of Company or
the Selling Shareholders on the one hand and the Underwriters on the other hand
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information supplied by the Company, the
Selling Shareholders or by the Underwriters and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Underwriters' respective obligations to contribute
pursuant to this Section 9 are several in proportion to the respective number
of Shares they have purchased hereunder, and not joint.

                  (g) The Company, the Selling Shareholders and the
Underwriters agree that it would not be just or equitable if contribution
pursuant to this Section 9 were determined by pro rata allocation (even if the
Underwriters were treated as one entity for such purpose) or by any other
method of allocation that does not take account of the equitable considerations
referred to in paragraph (e) of this Section 9. The amount paid or payable by
an indemnified party as a result of the losses, claims, damages and liabilities
referred to in the immediately preceding paragraph shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
Section 9, no Underwriter shall be required to contribute any amount in excess
of the amount by which the total price at which the Shares underwritten by it
and distributed to the public were offered to the public exceeds the amount of
any damages that such Underwriter has otherwise been required to pay by reason
of such untrue


                                       22

<PAGE>   24



or alleged untrue statement or omission or alleged omission. No person guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The remedies provided for in this
Section 9 are not exclusive and shall not limit any rights or remedies which
may otherwise be available to any indemnified party at law or in equity.

                  (h) The indemnity and contribution provisions contained in
this Section 9 and the representations, warranties and other statements of the
Company and the Selling Shareholders contained in this Agreement shall remain
operative and in full force and effect regardless of (i) any termination of
this Agreement, (ii) any investigation made by or on behalf of any Underwriter
or any person controlling any Underwriter, any Selling Shareholder or any
person controlling any Selling Shareholder, or the Company, its officers or
directors or any person controlling the Company and (iii) acceptance of and
payment for any of the Shares.

                  10. TERMINATION. This Agreement shall be subject to
termination by notice given by you to the Company, if (a) after the execution
and delivery of this Agreement and prior to the Closing Date (i) trading
generally shall have been suspended or materially limited on or by, as the case
may be, any of the New York Stock Exchange or the Nasdaq National Market, (ii)
trading of any securities of the Company shall have been suspended on any
exchange or in any over-the-counter market, (iii) a general moratorium on
commercial banking activities in New York or Texas shall have been declared by
either Federal or New York or Texas State authorities or (iv) there shall have
occurred any outbreak or escalation of hostilities involving the United States
or any change in financial markets or any calamity or crisis that, in your
judgment, is material and adverse and (b) in the case of any of the events
specified in clauses (a)(i) through (iv), such event, singly or together with
any other such event, makes it, in your judgment, impracticable or inadvisable
to market the Shares on the terms and in the manner contemplated in the
Prospectus.

                  11.      EFFECTIVENESS; DEFAULTING UNDERWRITERS.  This 
Agreement shall become effective upon the execution and delivery hereof by the
parties hereto.

                  If, on the Closing Date or the Option Closing Date, as the
case may be, any one or more of the Underwriters shall fail or refuse to
purchase Shares that it has or they have agreed to purchase hereunder on such
date, and the aggregate number of Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase is not more than
one-tenth of the aggregate number of the Shares to be purchased on such date,
the other Underwriters shall be obligated severally in the proportions that the
number of Firm Shares set forth opposite their respective names in Schedule I
or Schedule II bears to the aggregate number of Firm Shares set forth opposite
the names of all such non-defaulting Underwriters, or in such other proportions
as you may specify, to purchase the Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase on such date; provided
that in no event shall the number of Shares that any Underwriter has agreed to
purchase pursuant to this Agreement be increased pursuant to this Section 11 by
an amount in excess of one-ninth of such number of Shares without the written
consent of such Underwriter. If, on the Closing Date, any Underwriter or
Underwriters shall fail or refuse to


                                       23

<PAGE>   25



purchase Firm Shares and the aggregate number of Firm Shares with respect to
which such default occurs is more than one-tenth of the aggregate number of
Firm Shares to be purchased, and arrangements satisfactory to you and the
Company for the purchase of such Firm Shares are not made within 36 hours after
such default, this Agreement shall terminate without liability on the part of
any non-defaulting Underwriter or the Company. In any such case either you or
the Company shall have the right to postpone the Closing Date, but in no event
for longer than seven days, in order that the required changes, if any, in the
Registration Statement and in the Prospectus or in any other documents or
arrangements may be effected. If, on the Option Closing Date, any Underwriter
or Underwriters shall fail or refuse to purchase Additional Shares and the
aggregate number of Additional Shares with respect to which such default occurs
is more than one-tenth of the aggregate number of Additional Shares to be
purchased, the non-defaulting Underwriters shall have the option to (i)
terminate their obligation hereunder to purchase Additional Shares or (ii)
purchase not less than the number of Additional Shares that such non-defaulting
Underwriters would have been obligated to purchase in the absence of such
default. Any action taken under this paragraph shall not relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
this Agreement.

                  If this Agreement shall be terminated by the Underwriters, or
any of them, because of any failure or refusal on the part of the Company to
comply with the terms or to fulfill any of the conditions of this Agreement, or
if for any reason the Company shall be unable to perform its obligations under
this Agreement, the Company will reimburse the Underwriters or such
Underwriters as have so terminated this Agreement with respect to themselves,
severally, for all out-of-pocket expenses (including the fees and disbursements
of their counsel) reasonably incurred by such Underwriters in connection with
this Agreement or the offering contemplated hereunder.

                  12.      COUNTERPARTS. This Agreement may be signed in two 
or more counterparts, each of which shall be an original, with the same effect
as if the signatures thereto and hereto were upon the same instrument.

                  13.      APPLICABLE LAW. This Agreement shall be governed by 
and construed in accordance with the internal laws of the State of New York.

                  14.      HEADINGS. The headings of the sections of this 
Agreement have been inserted for convenience of reference only and shall not be
deemed a part of this Agreement.

                  15.      TIME OF THE ESSENCE. Time shall be of the essence of
this Agreement. As used herein, the term "business day" shall mean any day when
the Commission's office in Washington, D.C. is open for business.

                  To induce the Underwriters that may participate in the Public
Offering to continue their efforts in connection with the Public Offering, the

have a one-time right to purchase, severally and not jointly, up to $27,000,000
Additional Securities at the Purchase Price.   If the Representatives, on
behalf of the Underwriters, elect to exercise such option, the Representatives
shall so notify the Company in writing not later than 30 days after the date of
this Agreement, which notice shall specify the number of Additional Securities
to be purchased by the Underwriters and the date on which such Securities are
to be purchased.  Such date may be the same as the Closing Date (as defined
below) but not earlier than the Closing Date nor later than ten business days
after the date of such notice.  Additional Securities may be purchased as
provided in Section 4 hereof solely for the purpose of covering over-allotments
made in connection with the offering of the Firm Securities.  If any Additional
Securities are to be purchased, each Underwriter agrees, severally and not
jointly, to purchase the principal amount at maturity of Additional Securities
that bears the same proportion to the total number of Additional Securities to
be purchased as the number of Firm Securities set forth in Schedule I hereto
opposite the name of such Underwriter bears to the total principal amount at
maturity of Firm Securities.

              The Company hereby agrees that, without the prior written consent
of Morgan Stanley & Co. Incorporated on behalf of the Underwriters, it will
not, during the period ending 90 days after the date of the Prospectus, (i)
offer, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase, loan or otherwise transfer or dispose of, directly or indirectly, any
shares of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock or (ii) enter into any swap or other arrangement
that transfers to another, in whole or in part, any of the economic
consequences of ownership of the Common Stock, whether any such transaction
described in clause (i) or (ii) above is to be settled by delivery of Common
Stock or such other securities, in cash or otherwise.  The foregoing sentence
shall not apply to, with respect to the Company: (A) the Shares to be sold
hereunder; (B) the issuance by the Company of shares of Common Stock upon the
exercise of an option or warrant or the conversion of a security outstanding on
the date hereof of which the Underwriters have been advised in writing; or (C)
any shares of Common Stock issued as payment of any part of the purchase price
for acquisitions of businesses by the Company.  The Company further agrees that,
without the prior written consent of Morgan Stanley & Co. Incorporated on behalf
of the Underwriters, it will not, during the period beginning on the date hereof
and continuing to and including the Closing Date, not offer, sell, contract to
sell or otherwise dispose of any debt securities of the Company or warrants to
purchase

              shall any notice have been given of any intended or potential
              downgrading or of any review for a possible change that does not
              indicate the direction of the possible change, in the rating
              accorded any of the Company's securities by any "nationally
              recognized statistical rating organization," as such term is
              defined for purposes of Rule 436(g)(2) under the Securities Act;

              amendments or supplements thereto subsequent to the date of this
              Agreement) that, in your judgment, is material and adverse and

              Prospectus.

              (b)    The Underwriters shall have received on the Closing Date a

       satisfied all of the conditions on its part to be performed or satisfied
       hereunder on or before the Closing Date.

       circumstances when the Prospectus is delivered to a purchaser, not
       misleading, or if, in the opinion of counsel for the Underwriters, it is
       necessary to amend or supplement the Prospectus to comply with
       applicable law, forthwith to prepare, file with the Commission and
       furnish, at its own expense, to the Underwriters and to the dealers

              (d)    To endeavor to qualify the Securities for offer and sale
       under the securities or Blue Sky laws of such jurisdictions as you shall
       reasonably request.

              (e)    To make generally available to the Company's security
       holders and to you as soon as practicable an earning statement covering
       the twelve-month period ending September 30, 1998 that satisfies the
       provisions of Section 11(a) of the Securities Act and the rules and
       regulations of the Commission thereunder.

              (f)    To apply the net proceeds from the sale of the Securities
       as set forth in the Prospectus.

              (g)    The Company has reserved and will continue to reserve, as
       long as any Securities are outstanding, a sufficient number of shares of
       Common Stock for issuance upon conversion of the Securities.

              (h)    The Company will not voluntarily claim and will actively
       resist any attempts to claim, the benefit of any usury laws against
       holders of the Securities.

              (i)    the outstanding shares of Common Stock are quoted on the
       Nasdaq National Market, and prior to the Closing Date, the Company will
       have accomplished the inclusion, subject only to notice of issuance, of
       the Securities and the Shares for quotation on the Nasdaq National
       Market.

              7.     EXPENSES.  Whether or not the transactions contemplated in
this Agreement are consummated or this Agreement is terminated, (a) the Company
agrees to pay or cause to be paid all expenses incident to the performance of
the Company and its obligations under this Agreement, including:  (i) the fees,
disbursements and expenses of the Company's counsel and the Company's

cost of printing or producing any Blue Sky or Legal Investment memorandum in
connection with the offer and sale of the Securities under state securities
laws and all expenses in connection with the qualification of the Securities
for offer and sale under state securities laws as provided in Section 7(d)
hereof, including filing fees and the reasonable fees and disbursements of
counsel for the Underwriters in connection with such qualification and in
connection with the Blue Sky or Legal Investment memorandum, (iv) all filing
fees and disbursements of counsel to the Underwriters incurred in connection
with the review and qualification of the offering of the Securities by the

incident to listing the Securities and Shares issuable upon conversion of the

Company hereunder for which provision is not otherwise made in this Section.

              8.     INDEMNITY AND CONTRIBUTION.  (a) The Company agrees to
indemnify and hold harmless each Underwriter and each person, if any, who
controls any Underwriter within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act from and against any and all
losses, claims, damages and liabilities (including, without limitation, any
legal or other expenses reasonably incurred in connection with defending or
investigating any such action or claim) caused by any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement or any amendment thereof, any preliminary prospectus or the
Prospectus (as amended or supplemented if the Company shall have furnished any
amendments or supplements thereto), or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages or liabilities are caused by any such untrue statement
or omission or alleged untrue statement or omission based upon information
relating to any Underwriter furnished to the Company in writing by such
Underwriter through you expressly for use therein.

              (b)    Each Underwriter agrees, severally and not jointly, to
indemnify and hold harmless the Company, the directors of the Company, the
officers of the Company who sign the Registration Statement and each person, if
any, who controls the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act from and against any and all
losses, claims, damages and liabilities (including, without limitation, any
legal or other expenses reasonably incurred in connection with defending or
investigating any such action or claim) caused by any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement or any amendment thereof, any preliminary prospectus or the
Prospectus (as amended or supplemented if the Company shall have furnished any
amendments or supplements thereto), or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, but only with
reference to information relating to such Underwriter furnished to the Company
in writing by such Underwriter





                                       15
<PAGE>   17
through you expressly for use in the Registration Statement, any preliminary
prospectus, the Prospectus or any amendments or supplements thereto.

              (c)    In case any proceeding (including any governmental
investigation) shall be instituted involving any person in respect of which
indemnity may be sought pursuant to paragraph (a) or (b) of this Section 8,
such person (the "INDEMNIFIED PARTY") shall promptly notify the person against
whom such indemnity may be sought (the "INDEMNIFYING PARTY") in writing and the
indemnifying party, upon request of the indemnified party, shall retain counsel
reasonably satisfactory to the indemnified party to represent the indemnified
party and any others the indemnifying party may designate in such proceeding
and shall pay the fees and disbursements of such counsel related to such
proceeding.  In any such proceeding, any indemnified party shall have the right
to retain its own counsel, but the fees and expenses of such counsel shall be
at the expense of such indemnified party unless (i) the indemnifying party and
the indemnified party shall have mutually agreed to the retention of such
counsel or (ii) the named parties to any such proceeding (including any
impleaded parties) include both the indemnifying party and the indemnified
party and representation of both parties by the same counsel would be
inappropriate due to actual or potential differing interests between them.  It
is understood that the indemnifying party shall not, in respect of the legal
expenses of any indemnified party in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for (i) the fees and expenses
of more than one separate firm (in addition to any local counsel) for all
Underwriters and all persons, if any, who control any Underwriter within the
meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act and (ii) the fees and expenses of more than one separate firm (in
addition to any local counsel) for the Company, its directors, its officers who
sign the Registration Statement and each person, if any, who controls the
Company within the meaning of either such Section, and that all such fees and
expenses shall be reimbursed as they are incurred.  In the case of any such
separate firm for the Underwriters and such control persons of any
Underwriters, such firm shall be designated in writing by Morgan Stanley & Co.
Incorporated.  In the case of any such separate firm for the Company, and such
directors, officers and control persons of the Company, such firm shall be
designated in writing by the Company.  The indemnifying party shall not be
liable for any settlement of any proceeding effected without its written
consent, but if settled with such consent or if there be a final judgment for
the plaintiff, the indemnifying party agrees to indemnity the indemnified party
from and against any loss or liability by reason of such settlement or
judgment.  Notwithstanding the foregoing sentence, if at any time an
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel as contemplated by the
second and third sentences of this paragraph, the indemnifying party agrees
that it shall be liable for any settlement of any proceeding effected without
its written consent if (i) such settlement is entered into more than 30 days
after receipt by such indemnifying party of the aforesaid request and (ii) such
indemnifying party shall not have reimbursed the indemnified party in
accordance with such request prior to the date of such settlement.  No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened proceeding in respect
of which any indemnified party is or could have been a party and indemnity
could have been sought hereunder by such indemnified party, unless such
settlement





                                       16
<PAGE>   18
includes an unconditional release of such indemnified party from all liability
on claims that are the  subject matter of such proceeding.

              (d)    To the extent the indemnification provided for in
paragraph (a) or (b) of this Section 8 is unavailable to an indemnified party
or insufficient in respect of any losses, claims, damages or liabilities
referred to therein, then each indemnifying party under such paragraph, in lieu
of indemnifying such indemnified party thereunder, shall contribute to the
amount paid or payable by such indemnified party as a result of such losses,
claims, damages or liabilities (i) in such proportion as is appropriate to
reflect the relative benefits received by the indemnifying party or parties on
the one hand and the indemnified party or parties on the other hand from the
offering of the Securities or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the indemnifying party or parties on the one hand
and of the indemnified party or parties on the other hand in connection with
the statements or omissions that resulted in such losses, claims, damages or
liabilities, as well as any other relevant equitable considerations.  The
relative benefits received by the Company on the one hand and the Underwriters
on the other hand in connection with the offering of the Securities shall be
deemed to be in the same respective proportions as the net proceeds from the
offering of the Securities (before deducting expenses) received by the Company
and the total underwriting discounts and commissions received by the
Underwriters, in each case as set forth in the table on the cover of the
Prospectus, bear to the aggregate Public Offering Price of the Securities. The
relative fault of Company on the one hand and the Underwriters on the other
hand shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by
the Company or by the Underwriters and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.  The Underwriters' respective obligations to contribute pursuant to
this Section 8 are several in proportion to the respective number of Securities
they have purchased hereunder, and not joint.

              (e)    The Company and the Underwriters agree that it would not
be just or equitable if contribution pursuant to this Section 8 were determined
by pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation that does not take account
of the equitable considerations referred to in paragraph (e) of this Section 8.
The amount paid or payable by an indemnified party as a result of the losses,
claims, damages and liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 7, no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Securities underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages that such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission.  No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of





                                       17
<PAGE>   19
such fraudulent misrepresentation.  The remedies provided for in this Section 8
are not exclusive and shall not limit any rights or remedies which may
otherwise be available to any indemnified party at law or in equity.

              (f)    The indemnity and contribution provisions contained in
this Section 8 and the representations, warranties and other statements of the
Company contained in this Agreement shall remain operative and in full force
and effect regardless of (i) any termination of this Agreement, (ii) any
investigation made by or on behalf of any Underwriter or any person controlling
any Underwriter, the Company, its officers or directors or any person
controlling the Company and (iii) acceptance of and payment for any of the
Securities.

              9.     TERMINATION.  This Agreement shall be subject to
termination by notice given by you to the Company, if (a) after the execution
and delivery of this Agreement and prior to the Closing Date (i) trading
generally shall have been suspended or materially limited on or by, as the case
may be, any of the New York Stock Exchange or the Nasdaq National Market, (ii)
trading of any securities of the Company shall have been suspended on any
exchange or in any over-the-counter market, (iii) a general moratorium on
commercial banking activities in New York or Texas shall have been declared by
either Federal or New York or Texas State authorities or (iv) there shall have
occurred any outbreak or escalation of hostilities involving the United States
or any change in financial markets or any calamity or crisis that, in your
judgment, is material and adverse and (b) in the case of any of the events
specified in clauses (a)(i) through (iv), such event, singly or together with
any other such event, makes it, in your judgment, impracticable or inadvisable
to market the Securities on the terms and in the manner contemplated in the
Prospectus.

              10.    EFFECTIVENESS; DEFAULTING UNDERWRITERS.  This Agreement
shall become effective upon the execution and delivery hereof by the parties
hereto.

              If, on the Closing Date or the Option Closing Date, as the case
may be, any one or more of the Underwriters shall fail or refuse to purchase
the Securities that it has or they have agreed to purchase hereunder on such
date, and the aggregate principal amount at maturity of Securities which such
defaulting Underwriter or Underwriters agreed but failed or refused to purchase
is not more than one-tenth of the aggregate principal amount at maturity of
Securities to be purchased on such date, the other Underwriters shall be
obligated severally in the proportions that the aggregate principal amount at
maturity of Securities of Firm Securities set forth opposite their respective
names in Schedule I bears to the aggregate principal amount at maturity of Firm
Securities set forth opposite the names of all such non-defaulting
Underwriters, or in such other proportions as you may specify, to purchase the
Securities which such defaulting Underwriter or Underwriters agreed but failed
or refused to purchase on such date; provided that in no event shall the
principal amount at maturity of Securities that any Underwriter has agreed to
purchase pursuant to this Agreement be increased pursuant to this Section by an
amount in excess of one-ninth of such aggregate principal amount at maturity of
Securities without the written consent of such Underwriter.  If, on the Closing
Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm
Securities and the aggregate principal amount at maturity of Firm Securities
with respect to which such default occurs





                                       18
<PAGE>   20
is more than one-tenth of the aggregate principal amount at maturity of Firm
Securities to be purchased, and arrangements satisfactory to you and the
Company for the purchase of such Firm Securities are not made within 36 hours
after such default, this Agreement shall terminate without liability on the
part of any non-defaulting Underwriter or the Company.   In any such case
either you or the Company shall have the right to postpone the Closing Date,
but in no event for longer than seven days, in order that the required changes,
if any, in the Registration Statement and in the Prospectus or in any other
documents or arrangements may be effected.  If, on the Option Closing Date, any
Underwriter or Underwriters shall fail or refuse to purchase Additional
Securities and the aggregate principal amount at maturity of Additional
Securities with respect to which such default occurs is more than one-tenth of
the aggregate principal amount at maturity of Additional Securities to be
purchased, the non-defaulting Underwriters shall have the option to (i)
terminate their obligation hereunder to purchase Additional Securities or (ii)
purchase not less than the principal amount at maturity of Additional
Securities that such non-defaulting Underwriters would have been obligated to
purchase in the absence of such default.  Any action taken under this paragraph
shall not relieve any defaulting Underwriter from liability in respect of any
default of such Underwriter under this Agreement.

              If this Agreement shall be terminated by the Underwriters, or any
of them, because of any failure or refusal on the part of the Company to comply
with the terms or to fulfill any of the conditions of this Agreement, or if for
any reason the Company shall be unable to perform its obligations under this
Agreement, the Company will reimburse the Underwriters or such Underwriters as
have so terminated this Agreement with respect to themselves, severally, for
all out-of-pocket expenses (including the fees and disbursements of their
counsel) reasonably incurred by such Underwriters in connection with this
Agreement or the offering contemplated hereunder.

              11.    COUNTERPARTS.  This Agreement may be signed in two or more
counterparts, each of which shall be an original, with the same effect as if
the signatures thereto and hereto were upon the same instrument.

              12.    APPLICABLE LAW.  This Agreement shall be governed by and
construed in accordance with the internal laws of the State of New York.

              13.    HEADINGS.  The headings of the sections of this Agreement
have been inserted for convenience of reference only and shall not be deemed a
part of this Agreement.

              14.    TIME OF THE ESSENCE.  Time shall be of the essence of this
Agreement.  As used herein, the term "business day" shall mean any day when the
Commission's office in Washington, D.C. is open for business.

Dear Sirs and Mesdames:

              The undersigned understands that Morgan Stanley & Co.
Incorporated ("Morgan Stanley") proposes to enter into an Underwriting
Agreement (the "Underwriting Agreement") with CORESTAFF, Inc., a Delaware
corporation (the "Company") providing for the public offering (the "Public
Offering") by the several Underwriters, including Morgan Stanley and MSIL (the
"Underwriters") of ___% Convertible Subordinated Notes due 2004, which are
convertible into shares of Common Stock, par value $.01 per share, of the
Company (the "Common Stock").

              To induce the Underwriters that may participate in the Public
Offering to continue their efforts in connection with the Public Offering, the
undersigned hereby agrees that, without the prior written consent of Morgan
Stanley on behalf of the Underwriters, it will not, during the period
commencing on the date hereof and ending 45 days after the date of the final
prospectus relating to the Public Offering (the "Prospectus"), (1) offer, sell,
contract to sell, sell any option or contract to purchase, purchase any option
or contract to sell, grant any option, right or warrant to purchase, loan or
otherwise transfer or dispose of, directly or indirectly, any shares of





                                       22
<PAGE>   24
Common Stock or any securities convertible into or exercisable or exchangeable
for Common Stock, or (2) enter into any swap or other arrangement that
transfers to another, in whole or in part, any of the economic consequences of
ownership of the Common Stock, whether any such transaction described in clause
(1) or (2) above is to be settled by delivery of Common Stock or such other
securities, in cash or otherwise.  The foregoing sentence shall not apply to
the sale of any Shares to the Underwriters pursuant to the Underwriting
Agreement.  In addition, the undersigned agrees that, without the prior written
consent of Morgan Stanley on behalf of the Underwriters, it will not, during
the period commencing on the date hereof and ending 45 days after the date of
the Prospectus, make any demand for or exercise any right with respect to, the
registration of any shares of Common Stock or any security convertible into or
exercisable or exchangeable for Common Stock.

              Whether or not the Public Offering actually occurs depends on a
number of factors, including market conditions.  Any Public Offering will only
be made pursuant to an Underwriting Agreement, the terms of which are subject
to negotiation between the Company and the Underwriters.



                                                  Very truly yours,

CORESTAFF, Inc.
4400 Post Oak Parkway, Suite 1130
Houston, Texas  77027

Ladies and Gentlemen:

         We have acted as counsel to CORESTAFF, Inc., a Delaware corporation
("CORESTAFF"), in connection with the preparation of the Registration Statement
on Form S-3 (the "Registration Statement") filed on July 17, 1997, with the
Securities and Exchange Commission (the "Commission") under the Securities Act
of 1933, as amended (the "Securities Act"), with respect to (a) CORESTAFF's (i)
Convertible subordinated notes due 2004 (the "Notes"), which may be convertible
into common stock, par value $.01 per share, of CORESTAFF ("Common Stock") and
(ii) shares of Common Stock (such Notes and Common Stock are collectively
referred to herein as the "Securities"), which Securities may be issued for an
aggregate initial offering price not to exceed $413,137,500, plus such amounts
for the registration of additional Securities pursuant to Rule 462(b) under the
Securities Act.

         We have examined originals or copies, certified or otherwise identified
to our satisfaction, of (i) the Restated Certificate of Incorporation and Bylaws
of CORESTAFF, each as amended to the date hereof, (ii) the Indenture (the
"Indenture") to be entered into between CORESTAFF and a trustee, in the form to
be included as an exhibit to the Registration Statement and (iii) such other
certificates, statutes and other instruments and documents as we considered
appropriate for purposes of the opinions hereafter expressed.

         In connection with this opinion, we have assumed that (i) the
Registration Statement, and any amendments thereto (including post-effective
amendments), and the Rule 462(b) Registration Statement (if any) will have
become effective; (ii) all Securities will be issued and sold in compliance with
applicable federal and state securities laws and in the manner described in the
Registration Statement and the applicable Prospectus; (iii) the Indenture will
be duly authorized, executed and delivered by CORESTAFF and a trustee qualified
under the Trust Indenture Act of 1939, as amended (the "TIA"), in substantially
the form reviewed by us; (iv)

Page 2

a definitive underwriting or similar agreement with respect to any
Securities offered will have been duly authorized and validly executed and
delivered by CORESTAFF and the other parties thereto; and (vi) any Securities
issuable upon conversion of the Notes being offered will have been duly
authorized, created and, if appropriate, reserved for issuance upon such
conversion.

         Based on the foregoing, we are of the opinion that:

         1.      With respect to Notes to be issued under the Indenture, when
(i) the Indenture has been duly qualified under the TIA; (ii) the Board of
Directors of CORESTAFF or, to the extent permitted by Section 141 of the
Delaware General Corporation Act (the "DGCL"), a duly constituted and acting
committee thereof (such Board of Directors or committee being referred to herein
as the "Board") has taken all necessary corporate action to approve the issuance
and terms of such Notes, the terms of the offering thereof and related matters;
(iii) the terms of such Notes and of their issuance and sale have been
established so as not to violate any applicable law or result in a default under
or breach of any agreement or instrument binding upon CORESTAFF and so as to
comply with any requirement or restriction imposed by any court or governmental
body having jurisdiction over CORESTAFF; and (iv) such Notes have been duly
executed, authenticated, issued and delivered in accordance with the provisions
of the Indenture and in accordance with the applicable definitive underwriting
or similar agreement approved by the Board upon payment of the consideration
provided for therein, such Notes will be legally issued and will constitute
valid and binding obligations of CORESTAFF, enforceable against CORESTAFF in
accordance with their terms, except as such enforcement is subject to any
applicable bankruptcy, insolvency, reorganization or other law relating to or
affecting creditors' rights generally and general principles of equity and will
be entitled to the benefits of the Indenture.

         2.      With respect to shares of Common Stock, when (i) the Board has
taken all necessary corporate action to approve the issuance and terms of the
offering thereof and related matters; and (ii) certificates representing the
shares of Common Stock have been duly executed, countersigned, registered and
delivered either (a) in accordance with the applicable definitive underwriting
or similar agreement approved by the Board upon payment of the consideration
therefor (not less than the par value of the Common Stock) provided for therein,
or (b) upon conversion of the Notes in accordance with the terms of such Notes
providing for such conversion, as approved by the Board, for the consideration
approved by the Board (not less than the par value of the Common Stock), the
shares of Common Stock will be duly authorized, validly issued, fully paid and
non-assessable.

         The foregoing opinions are limited in all respects to the laws of the
State of New York, the General Corporation Law of the State of Delaware and
federal laws.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.  By giving such consent, we do not admit that we are
within the category of persons whose consent is required under Section 7 of the
Securities Act or the rules and regulations of the Commission issued
thereunder.

                                        Very truly yours,

                                        /s/ VINSON & ELKINS L.L.P.
