     The following summary is qualified in its entirety by the more detailed
information and financial statements, including the notes thereto, which appear
elsewhere in this Prospectus.
 
     This Prospectus contains certain forward-looking statements with respect to
the business of the Company and the industry in which it operates. These
forward-looking statements are subject to certain risks and uncertainties which
may cause actual results to differ significantly from such forward-looking
statements. See "Risk Factors."
 
                                  THE COMPANY
 
   
     Administaff, Inc. ("Administaff" or the "Company") is a leading provider of
professional employer services, both in terms of number of worksite employees
and in terms of revenues, with current operations in 10 markets. The Company
serves over 1,400 client companies with approximately 23,000 worksite employees
as of September 30, 1996 and believes that it currently ranks, in terms of
revenues, as one of the three largest professional employer organizations in the
United States. The Company has grown significantly since it was founded in 1986.
Revenues (which include the payroll of worksite employees) were $4.1 million for
1987, the Company's first full year of operations, and increased to over $716
million for fiscal 1995, with 1995 gross profit and net income of $28.9 million
and $1.1 million, respectively. Houston is the Company's original location and
accounts for approximately 50% of the Company's revenue base as of September 30,
1996, with other Texas markets accounting for an additional 30%. In October
1993, the Company opened a sales office in Dallas as the first step in
implementing a long-term internal growth and expansion strategy. Subsequent to
obtaining expansion capital in May 1994, the Company opened sales offices in
Atlanta, Phoenix, Chicago and Washington D.C. during a twelve month period
beginning in October 1994. The Company opened a second office in Dallas in
January 1996 and opened an office in Denver in September 1996. The Company plans
to enter at least one new market or open at least one additional sales office in
an existing market in each quarter of 1997 and 1998.
    
 
   
     Administaff's goal is to improve the productivity and profitability of
small businesses (generally, businesses with 100 or fewer employees) by
relieving business owners and key executives of administrative and regulatory
burdens, enabling them to focus on the core competencies of their businesses,
and by promoting employee satisfaction through human resource management
techniques that improve employee performance. The Company provides a
comprehensive personnel management system which encompasses a broad range of
services, including benefits and payroll administration, medical and workers'
compensation insurance programs, tax filings, personnel records management,
liability management and other human resource services. The fees charged by the
Company (which averaged approximately 123.6% of total payroll costs during the
nine-month period ended September 30, 1996) are invoiced along with each
periodic payroll of the client and include the gross payroll of each client plus
the Company's estimated costs of paying employment related taxes, providing
human resource services, performing administrative functions, providing
insurance coverages and benefit plans and performing other services offered by
the Company. Administaff provides these services by entering into a Client
Service Agreement which establishes a three party relationship whereby the
Company and client act as co-employers of the worksite employees.
Responsibilities are allocated between the co-employers pursuant to the Client
Service Agreement, with Administaff assuming responsibility for personnel
administration and compliance with most employment-related governmental
regulations. The client company retains the employee's services in its business
and remains the employer for various other purposes. Companies providing
comprehensive services in this manner have come to be known as professional
employer organizations, or PEOs, as distinguished from "fee for service"
companies, such as payroll processing firms, human resource consultants and
safety consulting firms, that provide a specific service to a client under a
traditional two party contract.
    
 
     Growth in the PEO industry has been significant. According to the National
Association of Professional Employer Organizations ("NAPEO"), the number of
employees under PEO arrangements in the United States has grown from
approximately 10,000 in 1984 to approximately 2.0 million in 1995. NAPEO
statistics also reflect gross revenues earned by the PEO industry grew from $5.0
billion in 1991 to $13.8 billion in 1995,
 
                                        3

representing a compounded annual growth rate of approximately 29%. Despite this
industry growth, the Company believes that the target markets for its business
remain relatively untapped. NAPEO estimates that at the end of 1995 the PEO
industry served only approximately 70,000 businesses in the United States. In
contrast, the Small Business Administration (the "SBA") estimates that net
annual growth in the number of small businesses is approximately 75,000.
 
     Administaff believes that growth in the PEO industry is driven by the
increasingly complex legal and regulatory burdens placed on employers as well as
trends relating to the growth and productivity of the small business community
in the United States. The Company believes that the key factors which drive
small businesses to consider PEO services include (i) complex regulation of
labor and employment issues and the related costs of compliance, including the
allocation of time and effort to such functions by owners and key executives,
(ii) the need to provide competitive health care and related benefits to attract
and retain quality employees to small businesses and (iii) the increasing costs
associated with workers' compensation and health insurance coverage, workplace
safety programs and employee related complaints and litigation. Growth in the
PEO industry has also been influenced by growth of the small business sector.
According to reports published by the SBA, at year end 1993 there were more than
5.8 million businesses in the United States with fewer than 100 employees, up
from 3.9 million of such businesses at the end of 1980. In addition, the Company
believes that attempts to achieve higher levels of productivity in the workplace
have supported a movement toward the outsourcing of services such as payroll
administration and consulting on benefits, safety and other employee related
issues. Administaff believes that its specific model for delivery of a
comprehensive package of PEO services directly supports the small business goal
of improving productivity and competitiveness.
 
                                    STRATEGY
 
     The Company's objective is to become the leading provider of PEO services
in the United States while achieving sustainable revenue and income growth. Key
elements of the Company's strategy were developed by the Company's core
management team which has remained in place since the Company's founding in
1986. Since that time, the Company has concentrated substantial financial and
management resources on developing, defining and optimizing a personnel
management system for small businesses and on building an organizational
infrastructure designed to enable the Company to replicate proven growth
patterns while balancing revenue and income growth objectives. The key elements
of the Company's strategy include:
 
     o Providing the highest quality services to help improve the productivity
       and profitability of the Company's clients.
 
   
          Administaff focuses on providing high quality services that directly
     enhance the productivity and profitability of small businesses. Achieving
     these efficiencies not only provides an obvious benefit to clients, it also
     benefits the Company in three distinct ways. First, to the extent that
     enhanced productivity results in client growth, Administaff's revenue base
     also grows. Second, clients who experience improved profitability best
     understand the value of Administaff's services and prove to be the
     Company's most effective referral sources. Finally, client productivity
     facilitated by Administaff promotes a long-term client relationship.
     Although the Company's client service agreement provides for only a one
     year initial term and is terminable on 30-day's notice at any time, in
     excess of 80% of Administaff's clients remain for more than one year and
     the retention rate increases for clients who remain with Administaff for
     longer periods. In accordance with NAPEO standards, retention rates are
     calculated by dividing the number of Company clients at December 31 by the
     number of clients at January 1 of the same year plus clients added during
     such year.
    
 
     o Continuing to enter and establish a leading position in new markets.
 
          In 1993, the Company identified 36 markets as its most attractive
     expansion targets and since that time has opened sales offices in six of
     these markets. The Company plans to enter at least one new market or open
     one additional sales office in an existing market in each quarter of 1997
     and 1998 and believes that the proceeds from this offering will be
     sufficient to cover the costs of such expansion. Through the use of a
     market selection model which evaluates a broad range of criteria,
     Administaff selects new markets where it believes it is most likely to
     replicate its historical growth patterns and market
 
                                        4
<PAGE>   8
 
     penetration. While most of the Company's expansion has been the result of
     opening sales offices, the Company has and will continue to consider
     expansion through strategic acquisitions. The Company believes that
     increasing industry regulatory complexity, including the difficulties of
     complying with the applicable state laws and the increasing capital
     commitments required of PEOs to provide larger service delivery
     infrastructures and management information systems should lead to
     significant consolidation opportunities in the PEO industry. The Company's
     market development strategy combines intensive direct marketing efforts
     with a fully integrated public relations and advertising campaign. While
     the expense associated with entering and developing a new market is
     significant, the Company views this investment as essential to achieving
     desired growth and extending its national leadership position. The Company
     generally expects expenses in a new market to be covered by the gross
     profit from that market within two years.
 
     o Growing existing markets through additional market penetration and
       marketing alliances.
 
          The Company believes that additional market penetration in established
     markets offers significant growth potential. Based on information contained
     in a database developed by American Business Information, Inc. ("ABI"), the
     Company believes that it serves less than 6.0% of the total number of
     businesses in Houston meeting its target criteria described below. In
     established markets, the Company's ability to achieve its growth objectives
     is enhanced by a higher number of referrals, a higher client retention
     rate, a more experienced sales force and momentum in its marketing efforts.
     The Company is also actively pursuing the formation of certain strategic
     alliances with other providers of various administrative and office
     services to small businesses as an alternative method for achieving growth
     in existing markets. The Company selectively opens additional sales offices
     and hires additional sales personnel in established markets to capitalize
     on these advantages and to achieve higher penetration.
 
     o Targeting and enrolling clients that are consistent with the Company's
       overall strategy and risk profile objectives.
 
          The Company seeks to attract clients whose objectives in utilizing
     Administaff's PEO services primarily relate to enhancing productivity
     rather than short-term cost cutting. The Company's clients tend to be
     established, financially successful and likely to recognize the value of a
     broad range of services which enable the client to concentrate on its core
     business. Administaff's target client has from five to 100 employees and
     must meet certain additional criteria relating to industrial
     classification, workers' compensation, health and unemployment claims
     history and operating stability. These criteria, which constitute part of
     the Company's screening process, are intended to avoid a skewing of the
     Company's client base to higher risk clients. Through this process, the
     Company seeks to continue to build a solid client base characterized by
     high year-to-year retention and client employee growth while maintaining a
     predictable and controllable direct cost structure.
 
     o Capitalizing on economies of scale while actively managing and
       controlling direct costs.
 
          The Company enjoys economies of scale which allow it to provide small
     businesses with a level of human resource management typically found only
     in large corporations. The Company aggressively pursues scale advantages in
     order to maximize profits and to provide its clients with premium services
     at competitive prices. In this regard, Administaff focuses on key
     relationships with insurance providers to design coverage and premium
     structures that not only provide cost effective and appropriate protection
     for clients, but also enable the Company to control major components of its
     direct costs. These economies and tailored coverages are achievable both
     because of the Company's sophistication as a purchaser of insurance
     products and its status as a large customer of such providers. The Company
     also employs a variety of proactive personnel management techniques to help
     minimize the incidence and magnitude of employee claims, complaints and
     related costs. The Company expects the economies resulting from active
     control and management of direct costs will continue to enhance
     profitability.
 
   
     No assurance can be given that the Company will be successful in
implementing its strategy or that, even if successful, such implementation will
have the intended effects on the Company's future revenue, operating expenses or
net income.

                             per share), approximately $12 million will be
                             reserved to support expansion of the Company's
                             operations, including the opening of new geographic
                             markets, further penetration of existing markets by
                             opening new sales offices and, as opportunities
                             arise, expansion of the Company's client base in
                             new or existing markets through acquisitions.
                             Approximately $4.0 million of the remaining net
                             proceeds will be used to repay certain outstanding
                             subordinated notes, $2.5 million to exercise
                             certain options to repurchase Common Stock and

                             net proceeds will be used for working capital
                             purposes, which may include acquisitions of
                             existing PEO operations. The Company will not
                             receive any of the net proceeds attributable to the
                             sale of shares of Common Stock by the Selling
                             Stockholders. See "Use of Proceeds."

                                    RISK FACTORS
 
     An investment in the Company involves a significant degree of risk.
Prospective purchasers should carefully consider the factors set forth below, as
well as the other information provided elsewhere in this Prospectus, before
making an investment in the Common Stock.
 
     When used in this Prospectus, the words "anticipate," "estimate," "project"
and similar expressions are intended to identify forward-looking statements.
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 or projected. Among the key factors that have a
direct bearing on the Company's results of operations and the industry in which
it operates are the effects of various governmental regulations, the fluctuation
of the Company's direct costs and the costs and effectiveness of the Company's
expansion strategy. These and other factors are discussed below and elsewhere in
this Prospectus.
 
IRS AUDIT OF THE COMPANY'S 401(K) PLAN; IRS MARKET SEGMENT STUDY
 
   
     The Company's 401(k) Plan is currently under audit by the IRS for the year
ended December 31, 1993. Although the audit is for the 1993 plan year, certain
conclusions of the IRS would be applicable to subsequent years as well. In
addition, the IRS has established a Market Segment Study Group on Employee
Leasing for the purpose of identifying specific compliance issues prevalent in
certain segments of the PEO industry. Approximately 70 PEOs, including the
Company, have been randomly selected by the IRS for audit pursuant to this
program. One issue that has arisen from these audits is whether a PEO can be a
co-employer of worksite employees, including officers and owners of client
companies, for various purposes under the Internal Revenue Code of 1986, as
amended (the "Code"), including participation in the PEO's 401(k) plan. For a
discussion of the issues being considered by the Market Segment Study Group, see
"Industry Regulation -- Employee Benefit Plans" and "-- Federal Employment
Taxes." With respect to the 401(k) Plan audit, the Company understands that the
IRS group conducting the audit intends to seek technical advice from the IRS
National Office about whether participation in the 401(k) Plan by officers of
client companies is permitted under the Code (the "Technical Advice Request").
The Company also understands that, with respect to the Market Segment Study, the
IRS is similarly referring to the National Office the issue of whether a PEO and
a client company may be treated as co-employers of worksite employees for
certain federal tax purposes (the "Industry Issue"). The IRS audit group leader
has advised the Company that the finding of facts from the Company's audit will
be submitted with the group leader's conclusion that such a co-employer status
is not recognized under current tax law.
    
 
     Whether the National Office will address the Technical Advice Request
independently of the Industry Issue is unclear. The Company is not able to
predict either the timing or the nature of any conclusions that may be reached
with respect to the 401(k) Plan audit or the Market Segment Study. Should the
IRS conclude that the Company is not a "co-employer" of worksite employees for
purposes of the Code, worksite employees could not continue to make salary
deferral contributions to the 401(k) Plan or pursuant to the Company's cafeteria
plan or continue to participate in certain other employee benefit plans of the
Company. The Company believes that, although unfavorable to the Company, a
prospective application of such a conclusion (that is, one applicable only to
periods after such a conclusion is reached) would not have a material adverse
effect on its financial position or results of operations, as the Company could
continue to make available comparable benefit programs to its client companies
at comparable cost to the Company. However, if such conclusion were applied
retroactively to disqualify the 401(k) Plan for 1993 and subsequent years,
employees' vested account balances under the 401(k) Plan would become taxable,
the Company would lose its tax deductions to the extent its matching
contributions were not vested, the 401(k) Plan's trust would become a taxable
trust and the Company would be subject to liability with respect to its failure
to withhold applicable taxes with respect to certain contributions and trust
earnings. Further, the Company would be subject to liability, including
penalties, with respect to its cafeteria plan for the failure to withhold and
pay taxes applicable to salary deferral contributions by employees, including
worksite employees. In such a scenario, the Company also would face the risk of
client dissatisfaction and potential litigation. A retroactive
 
                                        9
<PAGE>   13
 
application by the IRS of an adverse conclusion would have a material adverse
effect on the Company's financial position and results of operations.
 
COSTS OF 401(K) PLAN COMPLIANCE
 
   
     In 1991 the Company engaged a third party vendor to be the 401(k) Plan's
record keeper and to perform certain required annual nondiscrimination tests for
the 401(k) Plan. Each year such record keeper reported to the Company that such
nondiscrimination tests had been satisfied. However, in August 1996 the 401(k)
Plan's record keeper advised the Company that certain of these tests had been
performed incorrectly for prior years and, in fact, that the 401(k) Plan had
failed certain tests for the 1993, 1994 and 1995 plan years. The Company has
subsequently determined that the 401(k) Plan also failed a nondiscrimination
test for 1991, a closed year for tax purposes. At the time the Company received
such notice, the period in which the Company could voluntarily "cure" an
operational defect had lapsed for all such years, except 1995. With respect to
the 1995 year, the Company will cause the 401(k) Plan to refund the required
excess contributions and earnings thereon to affected highly compensated
participants, and the Company will pay an excise tax of approximately $51,000.
Because the 401(k) Plan is under a current IRS audit, the IRS voluntary
correction program for this type of operational defect is not available to the
Company for years prior to 1995. Accordingly, the Company informed the IRS of
the prior testing errors for each of 1991, 1993 and 1994 and proposed a
correction that consists of corrective contributions by the Company to the
401(k) Plan with respect to these years and the payment by the Company of the
minimum penalty ($1,000) that the IRS is authorized to accept to resolve this
matter. The IRS responded that resolution of the nondiscrimination test failures
is premature until the National Office resolves the Technical Advice Request.
The Company recorded a reserve during the third quarter of 1996 with respect to
these 401(k) Plan matters. The amount of such reserve is the Company's estimate
of the cost of corrective measures and penalties, although no assurance can be
given that the actual amount that the Company may ultimately be required to pay
will not substantially exceed the amount so reserved. Based on its preliminary
discussions with the IRS and its understanding of the settlement experience of
other companies, the Company does not believe that the ultimate resolution of
the nondiscrimination test issue will have a material adverse effect on the
Company's financial condition or results of operations, although no assurance
can be given by the Company because the ultimate resolution of this matter will
be determined in a negotiation process with the IRS.
    
 
STATE AND LOCAL REGULATION
 
     The Company is subject to regulation by local and state agencies pertaining
to a wide variety of labor related laws. As is the case with the provisions of
the Code discussed above, many of these regulations were developed prior to the
emergence of the PEO industry and do not specifically address non-traditional
employers. Prior to 1993, the State Board of Insurance of Texas and the Texas
Employment Commission challenged the ability of a PEO to provide workers'
compensation insurance and health benefits and to pay unemployment taxes as an
employer of worksite employees. These challenges were ultimately addressed
through the passage of specific professional employer licensing legislation in
Texas. There can be no assurance that additional challenges will not be faced in
Texas or that similar challenges will not be encountered in other jurisdictions
in which the Company may choose to do business. See "Industry
Regulation -- State Regulation."
 
   
     While many states do not explicitly regulate PEOs, 16 states (including
Texas and Florida) have passed laws that have licensing or registration
requirements for PEOs and at least four states are considering such regulation.
Such laws vary from state to state but generally provide for monitoring the
fiscal responsibility of PEOs. While the Company generally supports licensing
regulation because it serves to validate the PEO relationship, there can be no
assurance that the Company will be able to satisfy licensing requirements or
other applicable regulations of any particular state in which it is not
currently operating but later commences operations. In addition, there can be no
assurance that the Company will be able to renew its licenses in the states in
which it currently operates upon expiration of such licenses. For a more
complete description of these regulations, see "Industry Regulation -- State
Regulation."

INCREASES IN HEALTH INSURANCE PREMIUMS, UNEMPLOYMENT TAXES AND WORKERS'
COMPENSATION RATES
 
     Health insurance premiums, state unemployment taxes and workers'
compensation rates are in part determined by the Company's claims experience and
comprise a significant portion of the Company's direct costs. The Company
employs extensive risk management procedures in an attempt to control its claims
incidence. However, should the Company experience a large increase in claim
activity, its unemployment taxes, health insurance premiums or workers'
compensation insurance rates may increase. The Company's ability to incorporate
such increases into service fees to clients is constrained by contractual
arrangements with clients, which may result in a delay before such increases can
be reflected in service fees. As a result, such increases could have a material
adverse effect on the Company's financial condition or results of operations.
 
LIABILITIES FOR CLIENT AND EMPLOYEE ACTIONS
 
     A number of legal issues remain unresolved with respect to the
co-employment arrangement between a PEO and its worksite employees, including
questions concerning the ultimate liability for violations of employment and
discrimination laws. The Administaff Client Service Agreement establishes the
contractual division of responsibilities between the Company and its clients for
various personnel management matters, including compliance with and liability
under various governmental regulations. However, because the Company acts as a
co-employer, the Company may be subject to liability for violations of these or
other laws despite these contractual provisions, even if it does not participate
in such violations. Although the Client Service Agreement provides that the
client is to indemnify the Company for any liability attributable to the conduct
of the client, the Company may not be able to collect on such a contractual
indemnification claim and thus may be responsible for satisfying such
liabilities. In addition, worksite employees may be deemed to be agents of the
Company, subjecting the Company to liability for the actions of such worksite
employees. See "Business -- Customers" and "Industry Regulation."
 
LIABILITY FOR WORKSITE EMPLOYEE PAYROLL
 
     Under the Administaff Client Service Agreement, the Company becomes a
co-employer of worksite employees and assumes the obligations to pay the
salaries, wages and related benefit costs and payroll taxes of such worksite
employees. As such a co-employer, the Company assumes such obligations as a
principal, not merely as an agent of the client company. The Company's
obligations include responsibility for (i) payment of the salaries and wages for
work performed by worksite employees, regardless of whether the client company
makes timely payment to the Company of the associated service fee, and (ii)
providing benefits to worksite employees even if the costs incurred by
Administaff to provide such benefits exceed the fees paid by the client company.
During the period from January 1, 1987 through September 30, 1996, the Company
has recorded a total of $419,000 in bad debt expense on approximately $3.4
billion of total revenues. No assurance can be given whether the Company's
ultimate liability for worksite employee payroll and benefits costs will have a
material adverse effect on its financial condition or results of operations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Direct Costs."
 
LOSS OF BENEFIT PLANS
 
     The maintenance of health and workers' compensation insurance plans that
cover worksite employees is a significant part of the Company's business. The
current health and workers' compensation contracts are provided by vendors with
whom the Company has an established relationship, and on terms that the Company
believes to be favorable. While the Company believes that replacement contracts
could be secured on competitive terms without causing significant disruption to
the Company's business, there can be no assurance in this regard.
 
   
POSSIBLE ADVERSE APPLICATION OF OTHER FEDERAL AND STATE LAWS
    
 
   
     As a major employer, the Company's operations are affected by numerous
federal and state laws relating to labor, tax (in addition to the provisions of
the Code discussed above) and employment matters. By entering into a co-employer
relationship with employees assigned to work at client company locations, the
Company
    
 
                                       11
<PAGE>   15
 
   
assumes certain obligations and responsibilities of an employer under these
laws. However, many of these laws (such as ERISA and federal and state
employment tax laws) do not specifically address the obligations and
responsibilities of non-traditional employers such as PEOs, and the definition
of "employer" under these laws is not uniform. In addition, many of the states
in which the Company operates have not addressed the PEO relationship for
purposes of compliance with applicable state laws governing the
employer/employee relationship. If these other federal or state laws are
ultimately applied to the Company's PEO relationship with its worksite employees
in a manner adverse to the Company, such an application could adversely affect
the Company's results of operations or financial condition. See "Industry
Regulation."
    
 
GEOGRAPHIC MARKET CONCENTRATION
 
     While the Company has operations in 10 markets, six of these represent
recent expansions. The Company's Houston and Texas (including Houston) markets
accounted for approximately 50% and 80%, respectively, of the Company's revenue
base as of September 30, 1996. Accordingly, while a primary aspect of the
Company's strategy is expansion in its current and future markets outside of
Texas, for the foreseeable future a significant portion of the Company's
revenues may be subject to economic factors specific to Texas (including
Houston). In addition, while the Company believes that its market expansion
plans will eventually lessen or eliminate this risk in addition to generating
significant revenue growth, there can be no assurance that the Company will be
able to duplicate in other markets the revenue growth and operating results
experienced in its Houston market. See "Business -- Strategy."
 
COMPETITION AND NEW MARKET ENTRANTS
 
   
     The PEO industry is highly fragmented, with approximately 2,000 companies
performing PEO services to some extent. Many of these companies have limited
operations and fewer than 1,000 worksite employees, but there are several
industry participants which are comparable in size to the Company. These
companies include Staff Leasing, Inc, headquartered in Bradenton, Florida,
Employee Solutions, Inc., headquartered in Phoenix, Arizona and The Vincam
Group, Inc., headquartered in Coral Gables, Florida. The Company also encounters
competition from "fee for service" companies such as payroll processing firms,
insurance companies and human resource consultants. Moreover, the Company
expects that as the PEO industry grows and its regulatory framework becomes
better established, well organized competition with greater resources than the
Company may enter the PEO market, possibly including large "fee for service"
companies currently providing a more limited range of services.
    
 
ADEQUACY OF ACCRUED WORKERS' COMPENSATION CLAIMS
 
     Prior to November 1994, when the Company purchased a guaranteed cost
workers' compensation insurance policy, the Company maintained loss-sensitive
policies, effectively leaving primary liability for workers' compensation claims
with the Company. The Company maintains an accrual for workers' compensation
claims for the periods such policies were in place and bases the amount of such
accruals on periodic reviews of open claims. While the Company believes all such
open claims are covered through an existing insurance contract, the Company
cannot predict with certainty whether the ultimate liability associated with
these open claims will exceed the limits of the insurance contract. Accordingly,
future changes in estimated amounts of the ultimate liability with respect to
these claims could have a material adverse effect on the Company's financial
condition or results of operations. See Note 1 of Notes to Consolidated
Financial Statements.
 
QUARTERLY FLUCTUATIONS IN EARNINGS AND IMPACT OF EMPLOYMENT RELATED TAXES
 
     The Company's operating results have historically fluctuated from quarter
to quarter. In addition, due to the timing of the assessment of employment
related taxes, the Company's gross profit margin typically improves from quarter
to quarter within each year with the first quarter generally the least
favorable. Employment related taxes are based on the cumulative earnings of
individual employees up to specified wage levels. Since the Company's revenues
related to an individual employee are earned and collected at a relatively
 
                                       12
<PAGE>   16
 
constant rate throughout each year, payment of such unemployment tax obligations
has a substantial impact on the Company's financial condition or results of
operations during the first six months of each year.
 
POTENTIAL CLIENT LIABILITY FOR EMPLOYMENT TAXES
 
     Pursuant to the Company's Client Service Agreement with its clients, the
Company assumes sole responsibility and liability for the payment of federal
employment taxes imposed under the Code with respect to wages and salaries paid
to its worksite employees. There are essentially three types of federal
employment tax obligations: (i) income tax withholding requirements; (ii)
obligations under the Federal Income Contribution Act ("FICA"); and (iii)
obligations under the Federal Unemployment Tax Act ("FUTA"). Under the Code,
employers have the obligation to withhold and remit the employer portion and,
where applicable, the employee portion of these taxes. Most states impose
similar employment tax obligations on the employer. While the Client Service
Agreement provides that the Company has sole legal responsibility for making
these tax contributions, the IRS or applicable state taxing authority could
conclude that such liability cannot be completely transferred to the Company.
Accordingly, in the event the Company fails to meet its tax withholding and
payment obligations, the client company may be held jointly and severally liable
therefor. While this interpretive issue has not, to the Company's knowledge,
discouraged clients from enrolling with the Company, there can be no assurance
that a definitive adverse resolution of this issue would not do so in the
future.
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company's success is dependent upon the continued contributions of its
key management personnel, some of whom were founders of the Company. Many of the
Company's key personnel would be difficult to replace. The Company's executives
are not subject to noncompetition agreements.
 
EXPENSES ASSOCIATED WITH EXPANSION
 
   
     Past and future operating results are impacted by the Company's market
expansion activities, including establishing and maintaining sales office
facilities, compensating newly hired sales associates and expanding advertising
efforts. The Company's operating results for 1993, 1994 and 1995 have included
$0.2 million, $1.0 million and $4.3 million, respectively, of operating expenses
incurred in new markets. For the nine months ended September 30, 1996, these
costs have totaled $4.5 million. The Company expects that investments in new
markets will continue at levels comparable to or greater than 1995 and 1996
through at least 1998, and that expenses in a new market will not be covered by
the gross profit from that market's revenues for approximately two years. While
the Company believes that its expansion program will ultimately lead to
increased profitability, there can be no assurance whether losses or diminished
profitability will be incurred in future periods as a result of the Company's
planned expansion.
    
 
FAILURE TO MANAGE GROWTH
 
     The Company has experienced significant growth and expects such growth to
continue for the foreseeable future. The Company plans to enter at least one new
market or open at least one additional sales office in an existing market in
each quarter of 1997 and 1998. As is described under the caption "-- Expenses
Associated with Expansion," expenses incurred in connection with the initial
expansion into new markets are significant. In addition, because each market
entry is affected by circumstances unique to its particular locale, there are
uncertainties associated with each new market entry. Accordingly, the Company's
expansion plan may place a significant strain on the Company's management,
financial, operating and technical resources. Failure to manage this growth
effectively could have a material adverse effect on the Company's financial
condition or results of operations.
 
   
NEED TO RENEW OR REPLACE CLIENT COMPANIES
    
 
   
     The Company's standard Client Service Agreement has an initial one-year
term and is subject to cancellation on 30 days' notice by either the Company or
the client. Accordingly, the short-term nature of the
    
 
                                       13
<PAGE>   17
 
   
Client Service Agreement makes the Company vulnerable to potential cancellations
by existing clients which could materially and adversely effect the Company's
financial condition and results of operations. In addition, the Company's
results of operations are dependent in part upon the Company's ability to retain
or replace its client companies upon the termination or cancellation of the
Client Service Agreement. Historically, between 15% and 20% of the Company's
clients have remained clients for less than one year and there can be no
assurance that the number of contract cancellations will not increase in the
future.
    
 
   
ANTI-TAKEOVER EFFECTS OF CERTAIN CHARTER AND BYLAW PROVISIONS AND DELAWARE LAW
    
 
   
     The Company's Certificate of Incorporation and Bylaws include provisions
that may have the effect of discouraging proposals by third parties to acquire a
controlling interest in the Company, which could deprive stockholders of the
opportunity to consider an offer that would be beneficial to them. These
provisions include (i) a classified Board of Directors, (ii) the ability of the
Board of Directors to establish a rights plan, establish a sinking fund for the
purchase or redemption of shares, fix the number of directors and fill vacancies
on the Board of Directors, and (iii) restrictions on the ability of stockholders
to call special meetings, act by written consent or amend the foregoing
provisions. In addition, under certain conditions Section 203 of the General
Corporation Law of the State of Delaware (the "DGCL") would impose a three-year
moratorium on certain business combinations between a Delaware corporation and
an "interested stockholder" (in general, a stockholder owning 15 percent or more
of a corporation's outstanding voting stock). The existence of such provisions
may have a depressive effect on the market price of the Common Stock in certain
situations. See "Description of Capital Stock -- Provisions Having Possible
Anti-takeover Effect."
    
 
CONTROL BY EXISTING STOCKHOLDERS
 
     After this offering, the Company's officers, directors and principal
stockholders will beneficially own an aggregate of        shares of Common Stock
of the Company, constituting approximately     % of the outstanding shares of
Common Stock (     % if the Underwriters' over-allotment option is exercised in
full). Accordingly, such persons will be in a position to control actions that
require the consent of a majority of the Company's outstanding voting stock,
including the election of directors. A person beneficially owning more than
one-fifth of the Company's outstanding voting stock will be able to prevent
certain actions that require the affirmative vote of at least four-fifths of the
Company's outstanding voting stock. See "Principal and Selling Stockholders."
 
ABSENCE OF PRIOR TRADING MARKET; POTENTIAL VOLATILITY OF STOCK PRICE
 
   
     Prior to this offering, there has been no public market for the Common
Stock. Although the Common Stock has been approved for listing on the NYSE,
there can be no assurance that an active trading market will develop for the
Common Stock or, if one does develop, that it will be maintained. The public
offering price of the Common Stock will be negotiated between the Company and
the representatives of the Underwriters. See "Underwriters" for information
relating to the factors considered in determining the initial public offering
price. The market price of the shares of Common Stock could be highly volatile,
fluctuating in response to factors such as variations in the Company's operating
results, announcements of new services or market expansions by the Company or
its competitors, or developments relating to regulatory or other issues
affecting the PEO industry.
    
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of substantial amounts of the Common Stock in the public market
following this offering could have an adverse effect on prevailing market prices
of the Common Stock. All of the shares of the Company's currently outstanding
Common Stock are eligible for sale pursuant to the exemption from registration
under Rule 144 under the Securities Act, subject to applicable holding period,
volume and other limitations. In addition, after giving effect to the use of
proceeds described herein, certain holders of Common Stock will have
registration rights for an aggregate of up to 2,464,082 shares of Common Stock.
However, the officers, directors and certain stockholders of the Company who,
upon the completion of this offering, will beneficially own an aggregate of
approximately        shares of Common Stock have agreed with the Underwriters
not to
 
                                       14
<PAGE>   18
 
sell any of their shares for a period of 180 days from the date of this
Prospectus without the prior written consent of the Representatives of the
Underwriters. See "Shares Eligible for Future Sale."
 
DILUTION

                                  THE COMPANY
 
     The Company was originally organized in 1986 as a Texas corporation. Prior
to the consummation of this offering, the Company reorganized into Delaware by
completing a merger with a subsidiary of a Delaware corporation established by
the Company for this purpose. In conjunction with such merger, each of the
Company's stockholders exchanged their shares in the Texas corporation for
Common Stock of the Company on the basis of two shares of Common Stock for every
three shares of common stock of the Texas corporation. The Company's resulting
structure is that of a Delaware holding company whose only asset is the capital
stock of its operating subsidiary. All information in this Prospectus gives
effect to this reorganization.
 
     The Company's corporate headquarters are located at 19001 Crescent Springs
Drive, Kingwood, Texas 77339-3802, and its telephone number is (713) 358-8986.
 
                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the 3,000,000 shares of
Common Stock being offered by the Company hereby (assuming an offering price of
$          per share, the midpoint of the price range set forth on the cover of
this Prospectus, and after deducting estimated underwriting discounts and
commissions and estimated expenses of $          ) are estimated to be
$          . Of these proceeds, the Company currently expects to allocate
approximately $12.0 million to the opening of sales offices in new geographic
markets as well as in established markets and believes that this allocation will
be sufficient to fund the Company's expansion plans through 1997 and 1998. In
addition, the Company intends to utilize approximately $7.7 million of such
proceeds as follows: (i) $4.0 million to repay all of its 13% Subordinated Notes
(the "Notes") held by the Board of Trustees of the Texas Growth Fund, as Trustee
for the Texas Growth Fund-1991 Trust ("TGF"), (ii) approximately $2.5 million to
exercise its option to repurchase 348,945 shares of Common Stock from Pyramid
Ventures, Inc. ("PVI") and its option to repurchase 173,609 warrants to purchase
shares of Common Stock from TGF, and (iii) approximately $0.7 million to retire
the current balances of certain secured loans (the "Secured Loans") incurred in
connection with the purchase of real estate for the Company's headquarters. The
balance of the proceeds (estimated to be approximately $     million), will be
used for working capital purposes, which may include acquisitions of existing
PEO operations should favorable acquisition opportunities arise. Pending the
application of such funds, the Company intends to invest the net proceeds of
this offering in diversified, highly-liquid, investment grade, interest-bearing
instruments.
    
 
     The Notes, which are to be redeemed pursuant to optional prepayment
provisions, mature in May 1999 and accrue interest at an annual rate of 13%
payable quarterly. The Secured Loans consist of three separate notes ranging
from $73,000 to $462,000 in outstanding principal amount, with payments
aggregating from approximately $11,000 to $84,000 annually, and with interest
rates ranging from approximately 8.4% to 9.5% as of September 30, 1996. See Note
3 of Notes to Consolidated Financial Statements (unaudited) for the Interim
Period Ended September 30, 1996.
 
                                DIVIDEND POLICY
 
     The Company has not paid cash dividends on its Common Stock since its
formation and does not anticipate declaring or paying dividends on its Common
Stock in the foreseeable future. The Company expects that it will retain all
available earnings generated by the Company's operations for the development and
growth 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, general business conditions and such other factors as the Board of
Directors deems relevant. In addition, the Company's $10 million revolving
credit agreement prohibits the payment of dividends or other distributions on
the Common Stock, except that, so long as no default exists thereunder and,
after giving effect to such dividend or distribution, will exist thereunder, the
Company may pay dividends on its Common Stock. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."

                                    DILUTION
 
     The net tangible book value of the Company's Common Stock as of September
30, 1996 was $10.7 million, or $1.00 per share. Net tangible book value per
share represents the amount of total tangible assets less total liabilities,
divided by the number of shares of Common Stock outstanding. After giving effect
to the sale of shares of Common Stock offered by the Company hereby at an
assumed initial public offering price of $          per share and receipt of the
estimated net proceeds therefrom, the net tangible book value of the Company as
of September 30, 1996 would have been $          , or $          per share,
representing an immediate increase in net tangible book value of $          per
share to existing stockholders and an immediate dilution of $          per share
to new investors purchasing shares at the assumed initial public offering price.
The following table illustrates the resulting per share dilution with respect to
the shares of Common Stock offered hereby:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion should be read in conjunction with, and is
qualified in its entirety by, the Company's Consolidated Financial Statements
and Notes thereto included elsewhere in this Prospectus. Historical results are
not necessarily indicative of trends in operating results for any future period.
 
OVERVIEW
 
     Administaff provides a comprehensive personnel management system
encompassing a broad range of services, including personnel management, benefits
and payroll administration, medical and workers' compensation insurance
programs, tax filings, personnel records management, liability management and
related human resource services. Prior to October 1993, the Company's operations
were primarily the result of sales and marketing activity in the Houston market.
In October 1993 the Company opened a sales office in Dallas as the first step in
implementing a long-term internal growth and expansion strategy. Subsequent to
obtaining expansion capital in May 1994, sales offices were opened in Atlanta
and Phoenix in accordance with Administaff's market expansion plan. In the first
half of 1995, the Company established a presence in Chicago both by entering
into a referral agreement with an unaffiliated PEO organization and by opening a
sales office. The Company completed the scheduled opening of its
Baltimore/Washington, D.C. office in October 1995, opened a second office in
Dallas in January 1996, and a new office in Denver in September 1996. The costs
associated with this expansion into new markets (which for the purposes hereof
refers to Dallas and subsequently opened markets) have been significant and have
affected the results of operations for 1994, 1995 and the first nine months of
1996.
 
REVENUES
 
     Administaff's clients enter into a Client Service Agreement which
establishes a three-party relationship among the Company, the client and the
worksite employees. The agreement provides for an initial one year term, subject
to cancellation on 30 days' notice by either the Company or the client, and sets
forth the service fee payable to the Company. Such service fee, which
constitutes the Company's revenues, is based on the gross payroll of each
employee plus the estimated costs of employment related taxes, providing human
resource services, performing administrative functions, providing insurance
coverages and benefit plans and performing other services offered by the
Company. This structure yields a comprehensive service fee percentage to be
applied to each employee's gross pay. These fees are invoiced along with each
periodic payroll. Pursuant to the Client Service Agreement, the Company has the
obligation to provide the benefits and services enumerated in that agreement as
well as to pay the direct costs associated with such services, regardless of
whether the client company makes timely payment to the Company of the associated
service fee. The most significant direct costs associated with each Client
Service Agreement are the salaries and wages of worksite employees which
generally are disbursed promptly after the applicable client service fee is
received. For a description of additional direct costs, see "-- Direct Costs"
below.
 
     The Company's revenues are dependent on the number of clients enrolled, the
resulting number of employees paid each period, the gross payroll of such
employees and the number of employees enrolled in benefit plans. The Company's
expansion program is designed to broaden the scope of the Company's sales and
marketing efforts into new, strategically selected markets, where the Company's
objective is to duplicate the sales and marketing success experienced in the
Houston market to date. The Company has expanded its sales force from 22 at
December 31, 1993 to 80 at September 30, 1996. In addition to the Denver office
opened in September 1996, the Company expects to open at least one new market or
one additional sales office in existing markets in each quarter during 1997 and
1998. The Company further expects that each new sales office will have a staff
of six to ten sales associates.
 
DIRECT COSTS
 
     The Company's primary direct costs are (i) the salaries and wages of
worksite employees (payroll cost), (ii) employment related taxes, (iii) employee
benefit plans and (iv) workers' compensation insurance.
 
                                       21
<PAGE>   25
 
Salaries and wages of worksite employees are affected by the inflationary
effects on wage levels and by differences in the local economies of the
Company's markets. Changes in payroll costs have a proportionate impact on the
Company's revenues.
 
     Employment related taxes consist of the employer's portion of payroll taxes
required under the Federal Income Contribution Act ("FICA"), which includes
Social Security and Medicare, and federal and state unemployment taxes. The
federal tax rates are defined by the appropriate federal regulations. State
unemployment rates are subject to claims histories and vary from state to state.
 
     Employee benefit costs are comprised primarily of medical insurance costs
but also include costs of other employee benefits such as prescription card,
vision care, disability insurance and an employee assistance plan.
 
     Workers' compensation costs include premiums, administrative costs and
claims related expenses under the Company's workers' compensation program.
Currently, the Company is insured under a guaranteed cost plan whereby monthly
premiums are paid for coverage of all accident claims occurring during the
policy period. Prior to November 1994, the Company had been insured under two
other types of workers' compensation policies: a retrospective rating plan,
whereby monthly premiums were paid to the insurance carrier based on estimated
actual losses plus an administrative fee and a high deductible paid loss plan,
whereby monthly premiums were paid based on a $500,000 deductible per
occurrence. Costs related to these prior plans include estimates of ultimate
claims amounts that are recorded as accrued workers' compensation claims.
Changes in these estimates are reflected as a component of direct costs in the
period of the change.
 
     The Company's gross profit margin is determined in part by its ability to
accurately estimate and control direct costs and its ability to incorporate such
costs into the service fees charged to clients. The Company attempts to reflect
changes in the primary direct costs through adjustments in service fees charged
to clients, subject to contractual arrangements.
 
OPERATING EXPENSES
 
     The Company's primary operating expenses are salaries, wages and payroll
taxes of both corporate employees and sales associates, general and
administrative expenses and sales and marketing expenses. Prior to October 1993,
all of the Company's operating expenses were incurred through its corporate
offices in Houston. As a result of the Company's market expansion program,
however, operating expenses have increased significantly. The increases include
expenses associated with establishing and maintaining each new sales office
facility, the increased compensation related expenses of newly hired sales
associates and expansion of the Company's advertising efforts. In addition, the
anticipated growth as a result of the sales expansion is also reflected in
increased corporate operating expenses to provide expansion of the Company's
service capacity. The Company expects that the investment in new markets will
continue at a level comparable to or greater than 1995 and 1996 through at least
1998.
 
INCOME TAXES
 
     The Company's provision for income taxes typically differs from the U.S.
statutory rate of 34% due primarily to state income taxes. Deferred income taxes
reflect the net tax effects of temporary differences between the carrying
amounts of assets and liabilities used for financial reporting purposes and the
amounts used for income tax purposes. Significant items resulting in deferred
income taxes include accrued workers' compensation claims, depreciation and
amortization, state income taxes, client list acquisition costs, allowance for
uncollectible accounts receivable, net operating loss carryforwards and other
accrued liabilities. Changes in these items are reflected in the Company's
financial statements though the Company's deferred income tax provision.
 
QUARTERLY OPERATING RESULTS
 
     The Company's revenues have generally increased on a quarter-to-quarter
basis. Revenues in the fourth quarter of each year include the effects of bonus
payrolls of worksite employees, which are substantially higher in December of
each year. Gross profit margin typically improves from quarter to quarter within
a year, with
 
                                       22
<PAGE>   26
 
the first quarter generally the least favorable. Employment related taxes are
based on the cumulative earnings of individual employees up to a specified wage
level. Therefore, these expenses tend to decline over the course of the year.
Since the Company's revenues related to an individual employee are earned and
collected at a relatively constant rate throughout each year, payment of such
unemployment tax obligations has a substantial impact on the Company's working
capital and results of operations during the first six months of each year.
Other factors affecting the primary components of direct cost have enhanced or
mitigated this tendency. Examples of these factors include the effects of trends
in medical and workers' compensation claims, adjustments to benefit premiums and
changes in the types of benefit plans and workers' compensation programs. In
addition, beginning in October 1993, operating income and net income have been
affected by expenses incurred to open new markets and to increase sales and
service capacity and, in the third quarter of 1996, net income was affected by a
non-recurring charge relating to certain issues involving the failure of the
Company's 401(k) Plan to comply with certain nondiscrimination tests required by
the Code. See "Risk Factors -- Costs of 401(k) Plan Compliance," "Industry
Regulation -- Employee Benefit Plans" and Note 4 of Notes to Consolidated
Financial Statements (unaudited) for the interim period ended September 30,
1996.
 
     The following table presents certain unaudited results of operations data
for the interim quarterly periods from 1994 through the third quarter of 1996.
The Company believes that all adjustments, consisting only of normal recurring
adjustments, necessary to present fairly the results of operations in accordance
with generally accepted accounting principles, have been made. The results of
operations for any interim period are not necessarily indicative of the
operating results for a full year or any future period.

<PAGE>   27
 
  Revenues
 
     The Company's revenues increased 25.6% over the comparable nine month
period in 1995 due to an increased number of worksite employees paid during the
period and an increase in the revenue per employee. The Company's continued
expansion of its sales force through new market and sales office openings is the
primary factor contributing to the increased number of worksite employees. The
Company's new markets contributed $150.7 million of the Company's total revenues
for the first nine months of 1996 versus $72.3 million for the same period in
1995. In addition, the 1995 period includes approximately 1,400 new employees
enrolled through a referral agreement with an unaffiliated PEO in Chicago. The
Company added to its sales force in the Dallas market in January 1996 and the
Denver market in September 1996 and expects continued growth in the number of
worksite employees throughout the remainder of 1996 due to the continued effect
of sales in existing markets and expansion into new markets.
 
     The increase in revenue per employee of 8.7% directly relates to increases
in payroll cost per employee of 9.8%. This increase reflects the continuing
effects of the net addition, through the Company's sales efforts, of worksite
employees with higher average base pay than the existing client base.
 
  Gross Profit Margin
 
     The Company's gross profit margin increased from 4.0% for the first nine
months of 1995 to 4.1% for the first nine months of 1996. The primary factors
contributing to the increased gross profit margin were a decrease in
unemployment taxes relative to payroll cost and a slight decrease in the cost of
providing employee benefits as a percent of revenue. These factors were
partially offset by a decrease in the gross markup per person as a percent of
revenue.
 
     Employment related taxes as a percent of payroll cost declined from 8.5% in
the first nine months of 1995 to 7.6% for the same period in 1996. This
reduction was primarily due to reduced unemployment tax expense in the State of
Texas. The Company's unemployment tax rate in the State of Texas was
substantially lower in 1996 than 1995 due to the effects of a reorganization of
the Company's operating subsidiaries completed on January 1, 1996.
 
     The cost of providing employee benefits was slightly lower in 1996 versus
the same period in 1995 primarily due to decreased workers' compensation costs.
Workers' compensation costs decreased from 2.5% of payroll cost during the first
nine months of 1995 to 2.0% of payroll cost in the same period in 1996. This
reduction was due to the overall rate on the Company's current fixed premium
policy being lower than the previous policy. The current policy is in effect
through October 31, 1996. The Company expects to renew the workers' compensation
policy at rates comparable to the current policy. These reductions reflect a
reduced risk sensitivity of the current composition of the Company's client
base. In addition, the 1995 period included adjustments to accrued workers'
compensation claims relating to high deductible policies in place prior to
November 1994, which adjustments were not present in the 1996 period. Medical
plan premiums increased only slightly as a percent of revenues from 6.0% in the
first nine months of 1995 to 6.1% in the 1996 period.
 
     The markup per employee, while increasing 4.7%, decreased as a percent of
revenue from 19.8% in the 1995 period to 19.1% in the 1996 period. This
reduction was primarily due to the continued addition of higher wage, less risk
sensitive employees on which the Company charges lower overall rates as a
percentage of gross payroll.
 
  Operating Expenses
 
     Operating expenses decreased slightly as a percent of revenue from 3.8% in
the first nine months of 1995 to 3.6% for the comparable period in 1996. Total
operating expenses increased 19.2% while revenues and gross profit increased
25.6% and 28.9%, respectively. The overall increase in operating expenses can be
attributed to the following factors: (1) increased compensation related costs
(salaries, wages and payroll taxes and commissions) which increased in
proportion to revenues; (2) increased advertising expenses; and (3) increased
depreciation and amortization expense. General and administrative expenses were
slightly higher than the 1995 period. The factors noted above include the
effects of continued significant operating expenses in new
 
                                       24
<PAGE>   28
 
markets. These costs totaled $4.5 million for the nine months ended September
30, 1996 versus $2.8 million for the comparable period in 1995. Excluding the
impact of expenses incurred in the new markets, operating expenses as a whole
increased only $1.9 million, or 10.0% as compared to the same 1995 period.
 
     Total compensation costs, which include salaries, wages, payroll taxes and
commissions, increased 22.4% compared to the same period in 1995. Salaries and
wages increased at a higher rate while commissions were relatively unchanged due
to a restructuring of the Company's sales compensation plan to a more salary
based system. Overall, corporate staff, including sales personnel, increased
13.9% versus the same period in 1995. This increase is primarily due to
increased sales personnel and continued increases in corporate service capacity
during the second half of 1995. Since December 31, 1995, the corporate staff
level has remained relatively constant and is expected to increase only slightly
through the end of 1996.
 
     Advertising expenses increased by 17.1% primarily due to planned increases
relative to overall growth and expansion into new markets.
 
     Depreciation and amortization expense increased 69.5% over the same 1995
period. The Company placed into service a new corporate facility in February
1996 which has resulted in higher depreciation and amortization expense for the
nine month period as compared to 1995. In addition, capital expenditures
incurred during the previous 12 months related to the opening of new sales
offices as part of the Company's market expansion process and increases in
corporate service capacity contributed to the increase.
 
     General and administrative expenses as a percent of revenue declined
slightly versus the comparable 1995 period from 1.1% to 0.9%. This trend is due
to the Company's focused efforts to contain costs in its selling, service and
administrative functions.
 
  Net Income
 
     Interest expense increased $233,000 due to financing charges related to the
payment plan for the Company's annual workers' compensation insurance policy and
short-term borrowings on the Company's revolving line of credit. Interest income
decreased $38,000 versus the first nine months of 1995 due to lower level of
funds available to invest during the period.
 
   
     Other income (expense), net includes a non-recurring charge relating to
certain issues involving the failure of the Company's 401(k) Plan to comply with
certain nondiscrimination tests required by the Code, which charge is net of
amounts recoverable from the 401(k) Plan record keeper. See "Risk
Factors -- Costs of 401(k) Plan Compliance," "Industry Regulation -- Employee
Benefit Plans" and Note 4 of Notes to Consolidated Financial Statements
(unaudited) for the interim period ended September 30, 1996.
    
 
     The Company's provision for income taxes, which includes the effects of the
non-recurring charge for 401(k) Plan issues, differs from the U.S. statutory
rate of 34% due primarily to certain portions of the non-recurring charge being
non-deductible for income tax purposes. In addition, the Company's provision for
income taxes differs from the U.S. statutory rate due to state income taxes.
 
     Net income for the first nine months was $1.1 million. Excluding the
non-recurring charge and the related income tax effects of such charge, net
income would have been $1.8 million versus $0.6 million for the same period in
1995. The increased net income, excluding the non-recurring charge, as compared
with the 1995 period is attributable to the increased gross profit resulting
from the Company's overall revenue growth combined with slower growth in overall
operating expenses as discussed above.

</TABLE>
 
  Revenues
 
     The Company's revenues increased 26.9% over 1994 due primarily to an
increased number of worksite employees paid during the period. The Company
continued to expand its sales force in late 1994 and throughout 1995 by opening
sales offices in Atlanta (October 1994), Phoenix (January 1995), Chicago (April
1995) and Washington, D.C. (October 1995). These sales offices, along with the
continued maturation of the Dallas sales office (opened in the fourth quarter of
1993) were the primary factors contributing to the increased number of worksite
employees. The Company's new markets contributed $109.8 million of the Company's
1995 total revenues. In addition, in January 1995, the Company enrolled, through
a referral agreement with an unaffiliated professional employer organization in
Chicago, approximately 1,400 worksite employees which also contributed to the
increase over 1994. Revenue per employee increased only slightly versus 1994.
 
  Gross Profit Margin
 
     Gross profit margin decreased from 4.5% in 1994 to 4.0% in 1995. The
factors that caused this decline were a decline in the gross markup per worksite
employee (the net of revenue per worksite employee and payroll cost per worksite
employee) partially offset by a reduction, as a percent of revenue, in the costs
of providing employee benefits.
 
     The monthly revenue per worksite employee increased slightly during 1995
compared to 1994. The monthly payroll cost per worksite employee increased at a
greater rate than the increased revenue per worksite employee in the same period
resulting in a 3.2% reduction in the gross markup per worksite employee. This
reduction reflects the effects of a shift in the relative mix of worksite
employees paid by the Company to higher wage, less risk sensitive employees on
which the Company charges lower overall rates as a percentage of gross payroll.
 
     The reduction in employee benefits costs relative to revenues was primarily
due to a reduction in workers' compensation costs partially offset by increased
medical plan premiums. Workers' compensation costs declined primarily due to the
Company's conversion to a guaranteed cost policy in the fourth quarter of 1994
from the previous high deductible policy. The high deductible policy resulted in
increases to accrued workers' compensation claims which were significantly
higher during 1994 than during 1995. In addition, during the third quarter of
1995, the Company settled the remaining outstanding claims under certain
retrospective rating policies in effect in prior years resulting in a $1 million
reduction in overall workers' compensation costs during 1995. Medical plan
premiums increased compared to 1994 as favorable medical claims experience
during 1993 and early 1994 resulted in reduced health insurance premiums during
much of 1994.
 
                                       26
<PAGE>   30
 
     Employment related taxes relative to payroll costs increased slightly due
to state unemployment tax rate increases.
 
  Operating Expenses
 
     The Company's operating income decreased from $5.9 million in 1994 to $2.2
million in 1995. In addition to the decline in gross profit margin discussed
above, operating expenses increased from 3.4% of revenue in 1994 to 3.7% of
revenue in 1995. The increase in operating expenses relative to revenues can be
attributed primarily to increased salaries, wages and payroll taxes and the
selling, advertising and other general and administrative expenses incurred in
connection with the Company's market expansion plan.
 
     The operating expenses associated with the Company's market expansion plan
consist of those incurred in the new markets and those necessary for expansion
of sales and service capacity to meet expected growth. Expenses incurred in new
markets generally commence 90 days prior to the opening of a new sales office.
The Company generally expects the expenses in a new market to be covered by the
gross profit from that market's revenues within approximately two years. The
expenses in each new market are comprised of salaries, payroll taxes, benefits,
recruiting and training costs of newly hired sales associates, advertising and
public relations costs and general office expenses. These expenses for 1995
totaled approximately $4.3 million versus $987,000 in 1994.
 
     Costs associated with the expansion of sales and service capacity primarily
relate to the addition of corporate employees and other general and
administrative expenses. Excluding expenses directly incurred in new markets,
salaries, wages and payroll taxes increased $2.1 million during 1995 over those
incurred in 1994. The Company's average staff increased from 221 for 1994 to 320
for 1995. These increases reflected both an increase in the size of the
Company's sales force, from 22 at January 1, 1994 to 84 at December 31, 1995,
and an increase in the corporate infrastructure to manage the overall growth of
the Company.
 
     Advertising expenses in the Company's expansion markets were $1.8 million
in 1995 versus $516,000 during 1994. The Company's total advertising expenses
increased by $1.5 million, or 82%, over 1994.
 
     The higher level of revenues during 1995 also contributed to an increase of
approximately $711,000 for sales commissions. Such increase did not represent a
significant change from costs incurred during 1994 when considered as a percent
of payroll costs of worksite employees.
 
     Depreciation and amortization expense increased $327,000 in 1995 as
compared to 1994 due to capital expenditures incurred in connection with the
establishment of a disaster recovery computer and operations center and the
opening of new sales offices as part of the Company's market expansion plan.
 
  Net Income
 
     Interest expense increased $289,000 over 1994 due to a full year of
interest on the $4,000,000 subordinated debt borrowings compared to only seven
months in 1994. Interest income increased $219,000 over 1994 due to higher level
of funds available for investment during the period.
 
     The Company's provision for income taxes differs from the U.S. statutory
rate of 34% primarily due to state income taxes.
 
     Net income for 1995 was $1.1 million versus $3.8 million in 1994. The
decline in net income is attributable primarily to a decline in the overall
gross profit margin combined with increases in operating expenses associated
with the Company's market expansion plan as discussed above.

</TABLE>
 
  Revenues
 
     The Company's revenues increased 13.8% over 1993 due to a 6.2% increase in
the number of worksite employees paid during the year combined with a 6.9%
increase in the revenue per employee. The increased number of worksite employees
paid primarily resulted from the ongoing sales effort in existing markets. The
increase in revenue per worksite employee is directly related to the increase in
payroll cost per worksite employee discussed below.
 
  Gross Profit Margin
 
     Gross profit margin increased from 4.0% in 1993 to 4.5% in 1994. The key
factor that caused this increase was an overall reduction, as a percent of
revenue, in the costs of providing employee benefits, partially offset by a
slight increase in employment related taxes.
 
     The reduction in employee benefits costs relative to revenues was primarily
due to a reduction in health insurance premiums, which were lowered from 1993
levels as a result of the Company's favorable medical claims experience during
1993 and early 1994. However, workers' compensation costs increased in 1994
versus 1993 partially offsetting the effect of reduced health insurance costs.
Prior to November 1994 the Company was insured under a high deductible workers'
compensation policy. This type of policy resulted in the Company recording
significant additions to its accrued workers' compensation claims during 1994
resulting from revised ultimate loss estimates that relate to accidents covered
under this policy. In order to achieve more predictable costs for its workers'
compensation program, the Company purchased a guaranteed cost policy in the
fourth quarter of 1994. This policy provides "first dollar" coverage on all
claims arising under the policy with a fixed monthly premium for one year.
 
     The monthly revenue per worksite employee increased 6.9% over 1993, an
increase proportionate with the 7.1% increase in monthly payroll cost per
worksite employee. These factors combined for a 5.9% increase in gross markup
per employee, which reflect the Company's continuing efforts to attract higher
wage earners through its strategic target customer selection criteria. Increases
in wage levels throughout the Company's worksite employee population are also
reflected in the increases in monthly revenue and payroll cost per worksite
employee. These increases contributed to the overall 27.4% increase in gross
profit versus 1993.
 
  Operating Expenses
 
     The Company's operating income increased 87.4% from $3.1 million in 1993 to
$5.9 million in 1994. This increase resulted primarily from the increase in
gross profit discussed above. Operating expenses remained essentially unchanged
as a percentage of revenues.
 
                                       28
<PAGE>   32
 
     The operating expenses directly associated with the Company's market
expansion plan were $987,000 in 1994 versus $249,000 in 1993. Excluding expenses
directly incurred in the new markets, salaries, wages and payroll taxes of
corporate employees increased $1.7 million compared to 1993. The Company's
average corporate staff increased from 170 in 1993 to 221 in 1994 and the
Company had 192 corporate employees at December 31, 1993 versus 271 at December
31, 1994. These increases reflected both an increase in the size of the
Company's sales force from 22 at December 31, 1993 to 51 at December 31, 1994
and an increase in the corporate infrastructure required to process current and
future expansion. Included in this increase was the Company's formation of an
internal Information Technology department in July 1993 to assume
responsibilities previously outsourced by the Company.
 
     Higher revenues contributed to an increase of $256,000 in sales commissions
which are based on the gross payroll of worksite employees. These costs did not
change significantly from 1993 as a percent of payroll costs of worksite
employees. Advertising expenses increased by $185,000, or 11%, a movement
consistent with increasing revenues. The second half of 1994 reflected a further
acceleration in advertising expenditures which the Company expects to continue
into 1995 as part of its market expansion plan.
 
     Depreciation and amortization expense increased $206,000 over 1993 due to
capital expenditures incurred during the year related to the establishment of a
disaster recovery computer and operations center in Las Colinas (a suburb of
Dallas, Texas). Capital expenditures related to the opening of new sales offices
as part of the Company's market expansion plan also contributed to the increase.
 
  Net Income
 
     Interest expense increased $307,000 in 1994 due to the $4.0 million
subordinated debt incurred in May 1994. Interest income increased $129,000 over
1993 due to higher levels of funds available for investment following the
capital investment and subordinated debt proceeds received in May 1994.
 
     The Company's provision for income taxes differs from the U.S. statutory
rate of 34% due to state income taxes.
 
     All of the factors noted above, particularly the revenue growth and
resulting effect on gross profit, partially offset by the impact of the initial
stages of the Company's market expansion program, resulted in net income
increasing from $1.9 million in 1993 to $3.8 million in 1994.
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     The Company periodically evaluates its liquidity requirements, capital
needs and availability of resources in view of, among other things, expansion
plans, accrued workers' compensation insurance claims liabilities, debt service
requirements and other operating cash needs. As a result of this process, the
Company has, in the past, and may, in the future, seek to raise additional
capital or take other steps to increase or manage its liquidity and capital
resources. The Company currently believes that its cash on hand, cash flows from
operations and available borrowing capacity under the Credit Agreement will be
adequate to meet its liquidity requirements through at least 1997. The Company
will rely on these same sources, as well as public and private debt and equity
financing, to meet its long-term liquidity needs.
    
 
     The Company has $9.6 million in cash and cash equivalents at September 30,
1996 which is available to the Company for general corporate purposes,
including, but not limited to, current working capital requirements,
expenditures related to the continued expansion of the Company's sales force
through the opening of new sales offices, capital expenditures and repayments of
existing indebtedness. The Company has no significant long-term debt repayment
requirements during 1996.
 
     At September 30, 1996 the Company had positive working capital of $3.3
million which is a slight decline from $4.7 million at December 31, 1995. This
decline is due primarily to capital expenditures incurred during the period
offset partially by the net income for the period.
 
                                       29
<PAGE>   33
 
  Cash Flows From Operating Activities
 
     The Company's cash flows from operating activities increased substantially
from the comparable period in 1995. This increase resulted from federal and
state income tax payments relating to 1994 totaling $2.0 million paid in the
1995 period versus federal income tax refunds received totaling $3.5 million
during same period in 1996; higher payments in the 1995 period for previously
accrued workers' compensation claims; and the timing of accounts receivable
collection at the end of the respective periods.
 
  Cash Flows From Investing Activities
 
     Capital expenditures during the 1996 period totaled $3.4 million and were
incurred primarily in the first quarter to complete, furnish and equip a
Company-owned facility to accommodate continued growth in corporate employees.
This facility was opened in February 1996.
 
     Net dispositions of marketable securities of $4.0 million in the 1995
period resulted primarily from marketable securities with a carrying value of
$3.8 million reaching maturity and being converted to cash equivalents.
 
     In January 1995, the Company acquired a client base in its Chicago market
through a referral agreement calling for a referral fee which totaled $420,000
payable to the referring organization based on the number of worksite employees
enrolled by Administaff. The remainder of the increase in intangible assets in
both years relates to costs incurred for the rewrite of the Company's
computerized payroll software system in both periods.
 
  Cash Flows From Financing Activities
 
     Cash flows from financing activities in both periods include loans to
employees related to the federal income tax impact of the exercise of stock
options and, in the 1995 period, from the proceeds received from the exercise of
such options. In the 1996 period, the Company borrowed, on two occasions,
amounts against its $10 million revolving credit agreement totaling $2.5
million. Both borrowings were repaid during the third quarter of 1996.
 
  Credit Agreement
 
     In October 1995 the Company's wholly-owned subsidiary, Administaff of
Texas, Inc. ("Administaff of Texas"), entered into a $10 million revolving
credit agreement (the "Credit Agreement") with a bank. Such Credit Agreement
includes an agreement to issue standby letters of credit (in an amount not to
exceed a sublimit of $5,000,000). The Company is a guarantor under the Credit
Agreement. The Credit Agreement includes, among other covenants, a limitation on
the declaration and payment of dividends, a change of control provision and
other covenants customary in lending transactions of this type. At September 30,
1996 no borrowings were outstanding under the Credit Agreement. Borrowings under
the Credit Agreement bear interest at rates based on the bank's Corporate Base
Rate of LIBOR plus an applicable margin at the time of the borrowing.
 
  Expansion Plan
 
     The Company currently intends to allocate approximately $12 million of the
estimated $     million it will receive in net proceeds from this offering to
its expansion plan. The Company's expansion plan currently calls for opening a
sales office in each quarter of 1997 and 1998. While costs associated with
opening additional sales offices vary from market to market due to a number of
factors, including costs of advertising, the Company believes, based on
historical experience, that its expansion plan will require investments of
approximately $6 million in each of 1997 and 1998. The Company believes that the
portion of the offering proceeds allocated to expansion will be sufficient to
fund this expansion plan for the next two years. The balance of the proceeds of
the offering will be used for general corporate purposes and for acquisitions of
existing PEO operations should favorable acquisition opportunities arise.
Pending the application of the proceeds, the Company will invest such funds in
diversified, highly-liquid, investment grade, interest bearing
 
                                       30

instruments. The Company anticipates that such investments will generally
consist of U.S. government obligations, certificates of deposit issued by large
commercial banks, investment grade commercial paper, Eurodollar time deposits
and investment grade municipal bonds. See "Use of Proceeds."
 
OTHER MATTERS
 
     The Company's net deferred income tax assets and liabilities have
fluctuated significantly from December 31, 1994 to September 30, 1996. At
December 31, 1994, the Company had net deferred tax assets of $2.2 million,
relating primarily to accrued workers' compensation claims for which tax
deductions were not available until the claims were paid. During 1995, a
significant portion of these claims were paid resulting in substantial
deductions for income tax purposes. Therefore, as of December 31, 1995, net
deferred tax assets were reduced to near zero. The Company has net deferred tax
liabilities of $1.4 million at September 30, 1996 due primarily to the phase in
of a change in accounting method for income tax purposes. In January and May
1996, the Internal Revenue Service approved the Company's request for a change
in the method of accounting for PEO service fees and worksite employee payroll
costs to the accrual method. These changes were adopted for financial reporting
purposes effective January 1, 1994. For PEO service fees the change was approved
effective January 1, 1995 with a three year phase in period for the cumulative
effect of the change. For worksite employee payroll costs, the change was
approved effective January 1, 1995 with a one year phase in period for the
cumulative effect of the change. As a result, the Company amended its 1995
consolidated federal income tax return to account for these changes. The Company
received $3.5 million in federal income tax refunds in May and July 1996 related
to the original and amended tax returns. Deferred income taxes at September 30,
1996 reflect the effect of the three year phase in for the cumulative effect of
the change in accounting for PEO service fees as a component of net current and
noncurrent deferred tax liabilities. See Note 3 of Notes to Consolidated
Financial Statements (unaudited) for the interim period ended September 30,
1996.
 
     During the third quarter of 1996, the Company recorded an accrual for its
estimate of the cost of corrective measures and penalties relating to the 401(k)
Plan's failure to comply with certain nondiscrimination tests required by the
Code. See "Risk Factors -- Costs of 401(k) Plan Compliance," "Industry
Regulation -- Employee Benefit Plans" and Note 4 of Notes to Consolidated
Financial Statements (unaudited) for the interim period ended September 30,
1996. In addition, during the third quarter of 1996, the Company recorded an
asset for an amount recoverable from the 401(k) Plan's record keeper should the
Company ultimately be required to pay the amount accrued for such corrective
measures and penalties. The income tax effects of these items are reflected in
the Company's net deferred tax liabilities as of September 30, 1996. Based on
its understanding of the settlement experience of other companies in similar
situations, the Company does not believe the ultimate resolution of this 401(k)
Plan matter will have a material adverse effect on the Company's financial
condition, results of operations or liquidity.
 
SEASONALITY, INFLATION AND QUARTERLY FLUCTUATIONS
 
     The timing of the assessment of employment related taxes has a seasonal
effect on the Company's cash flows, with the Company generally having lower cash
flow from operations during the first six months of each year. As individual
worksite employees meet applicable wage limits for such taxes, the Company's
employment tax obligation declines which increases cash flows from operations
during the balance of the year.
 
     The Company believes the effects of inflation have not had a significant
impact on its results of operations or financial condition.
 
     The Company's operating results have historically fluctuated from quarter
to quarter. In addition, due to the timing of the assessment of employment
related taxes, the Company's gross profit margin typically improves from quarter
to quarter within each year with the first quarter generally being the least
favorable. Employment related taxes are based on the cumulative earnings of
individual employees up to a specified wage level. Since the Company's revenues
related to an individual employee are generally earned and collected at a
relatively constant rate throughout each year, payment of such unemployment tax
obligations has a substantial impact on the Company's financial condition or
results of operations during the first six months of each year.

                                    BUSINESS
 
   
     Administaff is a leading provider of professional employer services, both
in terms of number of worksite employees and in terms of revenues, with current
operations in 10 markets, including Houston, San Antonio, Austin, Orlando,
Dallas, Atlanta, Phoenix, Chicago, Baltimore/Washington, D.C. and Denver. The
Company serves over 1,400 client companies with approximately 23,000 worksite
employees as of September 30, 1996 and believes that it currently ranks, in
terms of revenues and worksite employee base, as one of the three largest
professional employer organizations in the United States. The Company has grown
significantly since it was founded in 1986. Revenues (which include the payroll
of worksite employees) were $4.1 million for 1987, the Company's first full year
of operations, and increased to over $716 million for fiscal 1995, with
corresponding gross profit and net income of $28.9 million and $1.1 million,
respectively. Houston is the Company's original location and accounts for
approximately 50% of the Company's current revenue base as of September 30,
1996, with other Texas markets accounting for an additional 30%. In October 1993
the Company opened a sales office in Dallas as the first step in implementing a
long-term internal growth and expansion strategy. Subsequent to obtaining
expansion capital in May 1994, the Company opened sales offices in Atlanta and
Phoenix in accordance with its market expansion plan. During 1995, the Company
established a presence in Chicago, both by entering into a referral agreement
with an unaffiliated PEO organization and by opening a sales office, and opened
an additional sales office in the Baltimore/Washington, D.C. area. The Company
opened a second office in Dallas in January 1996 and opened an office in Denver
in September 1996. The Company plans to enter at least one new market or open at
least one additional sales office in an existing market in each quarter of 1997
and 1998.
    
 
   
     Administaff's goal is to improve the productivity and profitability of
small businesses (generally, businesses with 100 or fewer employees) by
relieving business owners and key executives of administrative and regulatory
burdens, enabling them to focus on the core competencies of their businesses,
and by promoting employee satisfaction through human resource management
techniques that improve employee performance. The Company provides a
comprehensive personnel management system which encompasses a broad range of
services, including benefits and payroll administration, medical and workers'
compensation insurance programs, tax filings, personnel records management,
liability management and other human resource services. Administaff delivers
these services by becoming an employer for substantially all personnel
management matters. The client company retains the employee's services and
remains the employer for a limited number of other purposes.
    
 
PEO INDUSTRY
 
     The PEO industry began to evolve in the early 1980's largely in response to
the burdens placed on small to medium sized employers by an increasingly complex
legal and regulatory environment. While various service providers, such as
payroll processing firms, benefits and safety consultants and temporary services
firms were available to assist these businesses with specific tasks, PEOs began
to emerge as providers of a more comprehensive range of services relating to the
employer/employee relationship. As initially conceived, these services involved
the concept of staff leasing, whereby a service provider would become an
employer of the client company's employees, and would lease these employees to
the client to perform their intended functions at the worksite. As the industry
has evolved the term "professional employer organization" has come to describe
an entity which enters into a three-party relationship among the PEO, the client
business and the employee.
 
   
     Administaff establishes such three-party relationships through the Client
Service Agreement entered between the Company and the client business. The
Client Service Agreement provides for an initial one year term (subject to
cancellation on 30 days notice), sets forth the service fee payable to the
Company and establishes the division of responsibilities between Administaff and
the client as co-employers. In consideration for payment of the service fee
(which vary based upon relative employment tax rates, benefits participation,
workers' compensation risk profile, and level of pay of worksite employees, and
averaged approximately 123.6% of total payroll costs incurred during the
nine-month period ended September 30, 1996), the Company has the obligation to
pay the direct costs associated with the agreement, which generally consist of
(i) the salaries and wages of the worksite employees, (ii) employment related
taxes, (iii) employee
    
 
                                       32
<PAGE>   36
 
benefit plans, and (iv) workers' compensation insurance, regardless of whether
the client company pays Administaff the associated service fee. For a further
description of the Client Service Agreement and the responsibilities of
Administaff and the client company thereunder, see "-- Customers."
 
     PEO arrangements (including the Client Service Agreement) generally
transfer broad aspects of the employer/employee relationship to the PEO. Because
the business of the PEO is to enter into these relationships and provide
employee related services to a large number of employees, the PEO can achieve
economies of scale as a professional employer and perform the employment related
functions at a level typically available only to large corporations with
substantial resources to devote to human resources management.
 
     Growth in the PEO industry has been significant. According to NAPEO, the
number of employees under PEO arrangements in the United States has grown from
approximately 10,000 in 1984 to approximately 2.0 million in 1995. Administaff
believes that the key factors driving demand for PEO services include (i)
complex regulation of labor and employment issues and the related costs of
compliance, including the allocation of time and effort to such functions by
owners and key executives, (ii) the need to provide competitive health care and
related benefits to employees of small businesses, (iii) the increasing costs
associated with workers' compensation and health insurance coverage, workplace
safety programs, employee related complaints and litigation and (iv) trends
relating to the growth and productivity of the small business community in the
United States.
 
     A critical aspect of the growth of the PEO industry has been increasing
recognition and acceptance by federal and state governmental authorities of PEOs
and the employer/employee relationship created by PEOs. As the concept of PEO
services became understood by regulatory authorities, the regulatory environment
began to shift from one of hostility and skepticism to one of regulatory
cooperation with the industry. During the mid to late 1980's, legitimate
industry participants were challenged to overcome well publicized failures of
financially unsound and in some cases unscrupulous operators. Given this
environment, Administaff and other industry leaders, in concert with NAPEO, have
worked with the relevant government entities for the establishment of a
regulatory framework that would protect clients and employees and discourage
unscrupulous and financially unsound operators, and thereby promote the
legitimacy and further development of the industry. For a description of the
states in which the Company operates that require licensing or registration, see
"Industry Regulation -- State Regulation -- Other State Regulation."
 
     While many states do not explicitly regulate PEOs, 16 states (including
Texas and Florida) have enacted legislation containing licensing or registration
requirements and at least four states are considering such regulation. Such laws
vary from state to state but generally provide for monitoring the fiscal
responsibility of PEOs. State regulation assists in screening insufficiently
capitalized PEO operations and, in the Company's view, has the effect of
legitimizing the PEO industry generally by resolving interpretive issues
concerning employee status for specific purposes under applicable state law. The
Company has actively supported such regulatory efforts. As an active member of
NAPEO, the Company participated in the development of regulations affecting all
member organizations, and believes that these regulations further enhance the
credibility of the PEO industry. The Company does not view the burdens of
compliance with these regulations as material to its business operations.
 
     As the PEO industry has developed, the more established PEOs are
experiencing an increasing level of support from vendors who have a stake in the
success of the industry. For example, increased cooperation and flexibility from
insurance carriers have proved invaluable to Administaff in designing policies
that meet the needs of a large PEO.
 
STRATEGY
 
     The Company's objective is to become the leading provider of PEO services
in the United States while achieving sustainable revenue and income growth. Key
elements of the Company's strategy were developed by the Company's core
management team which has remained in place since the Company's founding in
1986. Since that time, the Company has concentrated substantial financial and
management resources on developing, defining and optimizing a personnel
management system for small businesses and on building an
 
                                       33
<PAGE>   37
 
organizational infrastructure designed to enable the Company to replicate proven
growth patterns while balancing revenue and income growth objectives. The key
elements of the Company's strategy include:
 
     o Providing the highest quality services to help improve the productivity
       and profitability of the Company's clients.
 
   
          Administaff focuses on providing high quality services that directly
     enhance the productivity and profitability of small businesses. Achieving
     these efficiencies not only provides an obvious benefit to clients, it also
     benefits the Company in three distinct ways. First, to the extent that
     enhanced productivity results in client growth, Administaff's revenue base
     also grows. Second, clients who experience improved profitability best
     understand the value of Administaff's services and prove to be the
     Company's most effective referral sources. Finally, client productivity
     facilitated by Administaff promotes a long-term client relationship.
     Although the Company's client services contracts provide for only a one
     year initial term and are terminable on 30-days' notice at any time, in
     excess of 80% of Administaff's clients remain for more than one year and
     the retention rate increases for clients who remain with Administaff for
     longer periods. In accordance with NAPEO standards, retention rates are
     calculated by dividing the number of Company clients at December 31 by the
     number of clients at January 1 of the same year plus clients added during
     such year.
    
 
     o Continuing to enter and establish a leading position in new markets.
 
          In 1993, the Company identified 36 markets as its most attractive
     expansion targets and has opened sales offices in six of these markets. The
     Company plans to enter at least one new market or open one additional sales
     office in an existing market in each quarter of 1997 and 1998 and believes
     that the proceeds from this offering will be sufficient to cover such
     expansion. Through the use of a market selection model which evaluates a
     broad range of criteria, Administaff selects new markets where it believes
     it is most likely to replicate its historical growth patterns and market
     penetration. While most of the Company's expansion has been the result of
     opening sales offices, the Company has and will continue to consider
     expansion through strategic acquisitions. The Company believes that
     increasing industry regulatory complexity, including the difficulties of
     complying with the applicable state laws, and the increasing capital
     commitments required of PEOs to provide larger service delivery
     infrastructures and management information systems should lead to
     significant consolidation opportunities in the PEO industry. The Company's
     market development strategy combines intensive direct marketing efforts
     with a fully integrated public relations and advertising campaign. While
     the expense associated with entering and developing a new market is
     significant, the Company views this investment as essential to achieving
     desired growth and extending its national leadership position. The Company
     generally expects expenses in a new market to be covered by the gross
     profit from that market within two years.
 
     o Growing existing markets through additional market penetration and
       marketing alliances.
 
          The Company believes that additional market penetration in established
     markets offers significant growth potential. Based on information contained
     in a database developed by ABI, the Company believes that it serves less
     than 6.0% of the total number of businesses in Houston meeting its target
     criteria described below. In established markets, the Company's ability to
     achieve its growth objectives is enhanced by a higher number of referrals,
     a higher client retention rate, a more experienced sales force and momentum
     in its marketing efforts. The Company is also actively pursuing the
     formation of certain strategic alliances with other providers of various
     administrative and office services to small businesses as an alternative
     method for achieving growth in existing markets. The Company selectively
     opens additional sales offices and hires additional sales personnel in
     established markets to capitalize on these advantages and to achieve higher
     penetration.
 
     o Targeting and enrolling clients that are consistent with the Company's
       overall strategy and risk profile objectives.
 
          The Company seeks to attract clients whose objectives in utilizing
     Administaff's PEO services primarily relate to enhancing productivity
     rather than short-term cost cutting. The Company's clients
 
                                       34
<PAGE>   38
 
     tend to be established, financially successful and likely to recognize the
     value of a broad range of services which enable the client to concentrate
     on its core business. Administaff's target client has from five to 100
     employees and must meet certain additional criteria relating to industrial
     classification, workers' compensation, health and unemployment claims
     history and operating stability. These criteria, which constitute part of
     the Company's screening process, are intended to avoid a skewing of the
     Company's client base to higher risk clients. Through this process, the
     Company seeks to continue to build a solid client base characterized by
     high year-to-year retention and client employee growth while maintaining a
     predictable and controllable direct cost structure.
 
     o Capitalizing on economies of scale while actively managing and
       controlling direct costs.
 
          The Company enjoys economies of scale which allow it to provide small
     businesses with a level of human resource management typically found only
     in large corporations. The Company aggressively pursues scale advantages in
     order to maximize profits and to provide its clients with premium services
     at competitive prices. In this regard, Administaff focuses on key
     relationships with insurance providers to design coverage and premium
     structures that not only provide cost effective and appropriate protection
     for clients, but also enable the Company to control major components of its
     direct costs. These economies and tailored coverages are achievable both
     because of the Company's sophistication as a purchaser of insurance
     products and its status as a large customer of such providers. The Company
     also employs a variety of proactive personnel management techniques to help
     minimize the incidence and magnitude of employee claims, complaints and
     related costs. The Company expects the economies resulting from active
     control and management of direct costs will continue to enhance
     profitability.
 
   
     No assurance can be given that the Company will be successful in
implementing its strategy or that, even if successful, such implementation will
have the intended effects on the Company's future revenue, operating expenses or
net income.
    
 
CLIENT SERVICES
 
     Administaff provides a comprehensive Personnel Management System
encompassing a broad range of services, including personnel management, benefits
and payroll administration, medical and workers' compensation insurance
programs, tax filings, personnel records management, liability management and
related human resource services. Among the laws and regulations that may affect
a small business are the following:
 
     o Internal Revenue Code (IRC)
 
     o Federal Income Contribution Act (FICA)
 
     o Employee Retirement Income Security Act (ERISA)
 
     o Occupational Safety and Health Act (OSHA)
 
     o Federal Unemployment Tax Act (FUTA)
 
     o Fair Labor Standards Act (FLSA)
 
     o Consolidated Omnibus Budget Reconciliation Act of 1987 (COBRA)
 
     o Immigration Reform and Control Act (IRCA)
 
     o Title VII (Civil Rights Act of 1964)
 
     o Civil Rights Act of 1991
 
     o American with Disabilities Act (ADA)
 
     o Tax Equalization and Fiscal Responsibility Act (TEFRA)
 
     o Age Discrimination in Employment Act (ADEA)
 
     o Drug-Free Workplace Act
 
     o Consumer Credit Protection Act
 
     o The Family and Medical Leave Act of 1993
 
     o State unemployment and employment securities laws
 
     o State workers' compensation laws
 
     While these regulations are complex and in some instances overlapping,
Administaff assists in achieving compliance through providing services in four
primary categories: administrative functions, benefit plans and administration,
personnel management and liability management. Once a client company has
executed a Client Service Agreement, the Client Services Department serves as
the client's principal point of contact
 
                                       35
<PAGE>   39
 
with Administaff and coordinates the delivery of all of the services described
below. For a more detailed description of responsibility for compliance with
each of the laws set forth above, see "-- Customers."
 
     Administrative Functions. Administrative functions encompass a wide variety
of processing and record keeping tasks, mostly related to payroll
administration, government compliance and employee benefit filing. Specific
examples include payroll processing, payroll tax deposits, quarterly tax
reporting, employee file maintenance, unemployment claims, workers' compensation
reporting, and monitoring and responding to changing regulatory requirements.
 
     Benefit Plans and Administration. Administaff currently offers the
following plans that the client may elect to provide worksite employees:
comprehensive health, dental, vision, prenatal care, prescription card,
counseling, education assistance and adoption assistance. Insurance coverages
also include group term life, universal life, accidental death and dismemberment
and long-term disability. Each client company can select from among several
different packages of these plans in accordance with its needs. Administaff also
offers a retirement savings (401(k)) plan to its eligible employees. As part of
its service package, the Company administers these benefit plans and is
responsible for negotiating the benefits and costs of such plans. The Company's
Benefits Administration department serves as liaison for the delivery of such
services to the worksite employee and monitors and reviews claims for loss
control purposes. The Company believes that this type of intensive benefit
management is usually found only in larger companies that can spread program
costs across many employees. Moreover, the Company believes that the
availability and administration of these benefits tends to mitigate the
competitive disadvantage small businesses normally face in the areas of cost
control and employee recruiting and retention.
 
     Personnel Management. The wide variety of personnel management services
provided by Administaff allow its client companies access to resources normally
found only in the human resources departments of large companies. On-site
supervisors are provided with a detailed personnel guide, which sets forth a
systematic approach to administering personnel policies and practices including
recruiting, discipline and termination procedures. Personnel policies and
employee handbooks are reviewed and revised, if necessary, or customized
handbooks can be created. The Company assists clients with the development of
refined job descriptions as well as a systematic performance appraisal process.
A variety of employee assistance programs can be implemented where needed,
including orientation, training, counseling, substance abuse awareness and
outplacement services. In addition, clients' management are provided with
detailed information, compiled from the Company's experience, regarding
competitive salaries for a wide range of positions across the country.
 
     Liability Management. Liability management services consist of several
functions. First, pursuant to the Company's Client Service Agreement and basic
to the Administaff client relationship, the Company assumes many of the
liabilities associated with being an employer. These include liability for
compliance with payroll tax reporting and payment obligations, workers'
compensation regulations, COBRA, the Immigration Reform and Control Act and the
Consumer Credit Protection Act. For those potential liabilities that Administaff
does not assume, the Company assists its clients in managing and limiting
exposure. This management for many clients includes first time and ongoing
safety inspections as well as the implementation of safety programs designed to
reduce workers' compensation claims. Administaff also advises clients on
avoiding liability for discrimination, sexual harassment and civil rights
violations and participates in termination decisions to attempt to secure
protection from liability on those grounds. When a claim arises, the Company
often assists in the client's defense regardless of whether the Company has been
named directly. The Company's Legal Department employs attorneys specializing in
several areas of employment law and has broad experience in disputes concerning
the employer/employee relationship. This expertise allows Administaff's clients
to contest many claims which they might otherwise have been inclined to settle.
The Company also monitors changing government regulations and notifies clients
of their effect on potential employer liability.
 
   
     Additional Services. All of Administaff's clients receive the foregoing
services as part of the Company's basic package in consideration for payment by
the clients of a comprehensive service fee. Administaff also provides
supplemental services to its clients for additional fees, with the actual fee
determined on the basis of the particular supplemental service to be rendered.
These services include prospective employee screening and
    
 
                                       36
<PAGE>   40
 
   
background investigations, drug testing, and pre-employment testing, scoring and
reporting. The Company will also stage a wide variety of seminars for both
employees and management, on subjects such as communication, leadership,
motivation and time and stress management skills. While these services
constitute an immaterial source of additional revenue to Administaff, they also
afford the Company an opportunity to solidify its relationships with existing
clients. Moreover, to the extent these services tend to reduce liability these
services serve as an additional element of the Company's liability and risk
management process.
    
 
CUSTOMERS
 
     Administaff's customer base consists of over 1,400 client companies,
representing approximately 23,000 worksite employees as of September 30, 1996.
The Company's clients have an average of 16 employees, with approximately 72%
having between five and 49 employees. The Company's client base is broadly
distributed throughout a wide variety of industries. As of September 30, 1996
the Company had customers representing approximately 430 Standard Industrial
Classification ("SIC") codes, and no more than 7% of the Company's customers
were classified in any one SIC code. Administaff's approximate client company
distribution by major SIC code industry grouping as of September 30, 1996 is set
forth below:
 
<TABLE>
        <S>                                                                       <C>

</TABLE>
 
     The Company attempts to maintain diversity within its client base to lower
its exposure to downturns or volatility in any particular industry and help
insulate the Company to some extent from general economic cyclicality. As part
of its client selection strategy, the Company offers its services to businesses
falling within specified SIC codes, essentially eliminating certain industries
that it believes present a higher risk of employee injury (such as roofing,
logging and oil and gas exploration). Businesses falling within other SIC codes
are not accepted by Administaff. All prospective customers are also evaluated
individually on the basis of workers' compensation risk, group medical history,
unemployment history and operating stability. On average, Administaff's clients
have been in business approximately 14 years before entering into the
Administaff relationship.
 
     All clients enter into Administaff's Client Service Agreement. The Client
Service Agreement provides for an initial one year term, subject to termination
by the Company or the client at any time upon 30 days' prior written notice.
After the initial term the contract may be renewed, terminated or continued on a
month-to-month basis, although the Company's standard practice is to contact its
clients prior to expiration of the initial term and attempt to renew the
relationship for another one year term.
 
     The Company's service fee is set forth in the Client Service Agreement, and
is based on a pricing model that takes into account the gross payroll of each
employee plus the estimated costs of paying employment related taxes, providing
human resource services, performing administrative functions and providing
insurance coverages and benefit plans and other services offered by the Company.
These items are combined to yield a service fee which is stated as a percentage
of gross pay. Fees are invoiced along with each periodic payroll. Client
specific information used to determine service fees is taken from a client
census which reflects information on each employee of the client, including
gross pay, workers' compensation classification, payroll frequency, whether
medical benefits are provided, and various other data. Fees for a particular
client are also influenced by that client's claims histories and other client
specific factors. Payroll data on an employee by
 
                                       37
<PAGE>   41
 
employee basis is entered into the Company's payroll database so that changes in
the client's employee base will be automatically reflected in client invoices
and in payroll disbursements made by Administaff.
 
     The Client Service Agreement also establishes the division of
responsibilities between Administaff and the client as joint employers. Pursuant
to the Client Service Agreement, Administaff is solely responsible for all
personnel administration and is liable for purposes of certain government
regulation. In addition, Administaff assumes liability for payment of salaries
and wages of its worksite employees and responsibility for providing employee
benefits to such persons, regardless of whether the client company makes timely
payment of the associated service fee. The client retains the employee's
services and remains liable for the purposes of certain government regulations,
compliance with which requires control of the worksite or daily supervisorial
responsibility or is otherwise beyond Administaff's ability to assume. A third
group of responsibilities and liabilities are shared by Administaff and the
client where such joint responsibility is appropriate. The specific division of
applicable responsibilities under the Client Service Agreement is as follows:

</TABLE>
 
     Because Administaff is a co-employer with the client company, it is
possible that Administaff could incur liability for violations of such laws even
if it is not responsible for the conduct giving rise to such liability. The
Client Service Agreement addresses this issue by providing that the Company or
the client will indemnify the other party for liability incurred to the extent
the liability is attributable to conduct by the indemnifying party.
Notwithstanding this contractual right to indemnification, however, it is
possible that Administaff could be unable to collect on a claim for
indemnification and may therefore be ultimately responsible for satisfying the
liability in question. The Company's total expense incurred with respect to such
exposure was approximately $117,000 for the year ended December 31, 1995 and
$49,000 for the nine months ended September 30, 1996.
 
     Administaff's client retention record reflects that a high percentage of
its clients remain with the Company from year to year. Historical retention
patterns indicate that in excess of 80% of Administaff's clients remain for over
one year and that the attrition rate declines for clients who remain with
Administaff for longer periods. Client attrition experienced by Administaff is
attributable to a variety of factors, including (i) termination by Administaff
resulting from the client's inability to make timely payments, (ii) client's
non-renewal due to price, (iii) client business failure or downsizing and (iv)
sale or disposition of the client company. The Company believes that only a
small percentage of nonrenewing clients withdrew due to dissatisfaction with
service or to retain the services of a competitor.
 
     Clients are required to pay Administaff no later than one day prior to the
applicable payroll date by wire transfer or automatic clearinghouse transaction,
and receipt of funds is verified prior to release of payroll. Although the
Company is ultimately liable as employer to pay employees for work previously
performed, it retains the ability to terminate the Client Service Agreement as
well as the employees upon non-payment by a client. This right and the periodic
nature of payroll, combined with client credit checks and the natural
 
                                       38

screening effect of the Company's client selection process, has resulted in an
excellent collections history. During the period from January 1, 1987 to
September 30, 1996, the Company has recorded a total of $419,000 in bad debt
expense on approximately $3.4 billion of total revenues.
 
MARKETING AND SALES
 
     Administaff's marketing strategy is based on the application of techniques
that have produced predictable results for the Company in the past. The Company
develops a mix of advertising media and a placement strategy tailored to each
individual market. After selecting a market and developing its marketing mix,
but prior to entering the market, Administaff engages in an organized media and
public relations campaign to prepare the market for the Company's entry, and to
begin the process of generating sales leads. Administaff markets its services
through a broad range of media outlets, including radio, newspapers, periodicals
and direct mail. The Company employs a local public relations firm in each of
its markets as well as an advertising firm to coordinate and implement its
marketing campaigns, and has developed an inventory of proven, successful radio
and newsprint advertisements which are utilized in this effort.
 
     In order to identify the most promising potential markets, the Company
employs a systematic market evaluation and selection process. The Company
evaluates a broad range of factors in the selection process, using a market
selection model that weights various criteria that the Company believes are
reliable predictors of successful penetration based on its experience. Among the
factors considered are (i) market size, in terms of small businesses engaged in
selected industries that meet the Company's risk profile, (ii) market
receptivity to PEO services, including considerations such as regulatory
environment, and relevant history with other PEO providers, (iii) existing
relationships within a given market, such as vendor or client relationships,
(iv) expansion cost issues, such as advertising and overhead costs, (v)
potential direct cost issues that bear on the Company's effectiveness in
controlling and managing the cost of its services, such as workers' compensation
and health insurance costs, unemployment risks and various legal and other
factors, (vi) a comparison of the services offered by Administaff to
alternatives available to small businesses in the relevant market, such as the
cost to the target clients of procuring services directly or through other PEOs
and (vii) long-term strategy issues, such as general perception of markets and
long-term revenue growth potential. Each of the Company's six newly opened
markets, beginning with Dallas in October 1993, was selected in this manner.
 
     Administaff generates sales leads from three primary sources: direct sales
efforts, advertising and referrals. These leads result in initial presentations
to prospective clients, and, ultimately, a predictable number of client census
reports. The client's census report reflects information gathered by the sales
associate about the prospect's employees, including job classification, state of
employment, workers' compensation claims history, health insurance claims
history, salary, and similar information for each employee, and a desired level
of benefits for the prospective client. This information is entered into the
Company's data processing system, which applies the prospect's employee
characteristics to Administaff's pricing model, leading to preparation of a bid.
Concurrently with this process, the prospective client's workers' compensation
and health insurance histories are forwarded to Company headquarters, where they
are evaluated from a risk management perspective. Unfavorable aspects of either
of these histories will result in termination of the sales effort and rejection
of the prospect. This prospective client screening process plays a vital role in
controlling the Company's benefits costs and limiting its exposure to liability.
 
     Upon completion of a favorable risk evaluation, the sales associate then
presents the prospective client with the Company's bid and attempts to enroll
the prospect. Each bid includes detailed information as to the rate (as a
percentage of gross payroll) that will be charged for each employee by category
(state of employment and job classification) and level of benefits. If a
prospect accepts Administaff's proposal, the new client is quickly incorporated
into the Company's system. The client executes the Client Service Agreement, and
an orientation team initiates the process of transferring employee related
functions to Administaff. See "-- Customers." The client's database is
transferred to the Client Services Department, where Account Executives assume
responsibility for administering the client's personnel and benefits, coordinate
the Company's response to the client's needs for administrative support and
respond to any questions or problems encountered by the client. See "-- Client
Services."

VENDOR RELATIONSHIPS
 
     Administaff provides benefits to its worksite employees under arrangements
with a variety of vendors. Although the Company believes that any of its benefit
contracts could be replaced if necessary with minimal disruption to its
operations, the Company considers four of such contracts to be significant
elements of the package of benefits provided to employees.
 
     The Company's group health insurance plan is a fully insured plan provided
by Aetna Life & Casualty Insurance Co. ("Aetna"). Each client company selects
from a range of health plan coverages available under the plan and Administaff's
fees to that client reflect the coverage options selected. The Company initiated
insurance coverage with Aetna in 1989, became fully insured in 1992 and has
maintained a fully-insured policy with Aetna since that time. The current policy
expires December 31, 1996. The policy requires the Company to fund claims and
premiums up to a specified monthly cap amount. Aetna is required to fund all
claims and premiums, if any, in excess of the monthly cap amount. Monthly cap
amounts are in place for quarterly periods and such cap amounts are adjustable,
based on claims experience, with six months' notice by Aetna. While Aetna bears
ultimate legal responsibility for all claims, because the Company bears the
burden of higher costs as claims experience increases, the Company seeks to
minimize health care claims through its benefits administration management
practices.
 
     The Company's workers' compensation policy, a guaranteed cost plan whereby
monthly premiums are paid for complete coverage of all claims under the policy,
was originally put in place with Reliance National Indemnity Co. ("Reliance") in
November 1994, and the current policy will continue in effect until October 31,
1996. The Company expects to renew the policy for another one-year term on
comparable terms to the current policy. Reliance has provided the Company's
workers' compensation policies since 1990.
 
     In addition to its health and workers' compensation insurance policies,
significant benefits contracts include the Company's long and short term
disability policies with Fortis Benefits Insurance Co., which were put in place
in January 1993 and August 1995, respectively, and continue until they are
replaced or canceled.
 
INFORMATION TECHNOLOGY
 
     The Company has developed state-of-the-art information technology capable
of meeting the demands of payroll and related processing for the Company's
worksite employees, satisfying the Company's administrative and management
information needs, and providing productivity enhancement tools to the Company's
corporate staff. While the Company utilizes commercially available software for
standard business functions such as finance and accounting, it has developed a
proprietary professional employer information system for the delivery of its
primary services. This system manages data relating to worksite employee
enrollment, human resource management, benefits administration, payroll
processing, management information, and sales proposal bid calculation
capabilities that are unique to the PEO industry and to Administaff. At the
heart of the system is a high volume payroll processing system that allows the
Company to produce and deliver hundreds of payrolls per day, each customized to
the needs of the client companies.
 
     Administaff's proprietary PEO information system is now in its third
generation, with the fourth generation nearing completion. The software has been
developed using Informix, a relational database and program development
language, and PowerBuilder, a state-of-the-art, object oriented client/server
development system. The software is designed to provide high volume professional
employer services utilizing a combination of on-line and batch processing
facilities and can be readily expanded to handle additional processing needs.
The system is accessed through a graphical user interface engineered to maximize
both the quality of Administaff's services and the efficiency with which they
are delivered.
 
     Administaff's primary information processing facility is located at the
Company's corporate headquarters in Kingwood, Texas (near Houston). A second
processing facility is located in Las Colinas, Texas (near Dallas). The Kingwood
facility handles approximately two-thirds of the Company's daily client service
load as well as administrative and management information processing. The Las
Colinas facility handles approximately one-third of the daily client service
load as well as acting as a disaster recovery facility for the Company capable
of handling all of the Company's operations for a short period of time.
 
                                       40
<PAGE>   44
 
     Administaff's principal computing platform is the IBM RISC/6000. The
Company utilizes six IBM RISC/6000s at its Kingwood facility and two at its Las
Colinas facility. These processing facilities are linked by a high speed wide
area network utilizing dedicated telecommunications facilities. The IBM
RISC/6000 computers are also connected by local area networks to more than 300
IBM PC workstations running Microsoft Windows(C) software. The Company's
district sales offices are equipped with Microsoft NT Advanced Server(C)
networks and are linked to the Kingwood and Las Colinas facilities through
public telecommunications facilities.
 
COMPETITION
 
     The PEO industry consists of approximately 2,000 companies, most of which
serve a single market or region. The Company believes that it is one of three
PEOs with annual revenue exceeding $500 million. The Company considers its
primary competition to be the traditional in-house provision of employee
services. In addition, the Company competes to some extent with fee-for-service
providers such as payroll processors and human resource consultants.
 
     Competition in the PEO industry revolves primarily around price, quality of
service, choice and quality of benefits and reputation. The Company believes
that reputation, national presence, regulatory expertise, financial resources,
risk management and data processing capability distinguish leading PEOs from the
rest of the industry. The Company believes that it competes favorably in these
areas.
 
CORPORATE OFFICE EMPLOYEES
 
     The Company had over 360 corporate office and sales employees as of
September 30, 1996. These employees are divided among the Company's 10
functional departments, with 25 employees in Corporate Services, 27 in Finance,
29 in Benefits Administration, 13 in Legal, 10 in Marketing, 28 in Information
Technology, 70 in Client Services, 125 in Sales (including 80 sales associates),
31 in Human Resources and three in Emerging Business Services, each as of
September 30, 1996. Approximately 240 employees are located at the Kingwood
headquarters, 26 are based at the Las Colinas facility, and the remainder
(principally the sales associates) are based at the Company's sales offices.
 
FACILITIES
 
     Administaff maintains two primary facilities. The corporate headquarters
are located in Kingwood, Texas (20 miles north of Houston), on approximately 17
acres owned by the Company. This location includes a 66,000 square foot campus
style facility and a recently renovated 76,000 square foot facility that serves
as the Company's operations and records retention facility. Together these
facilities house the Company's executive offices, corporate staff,
data-processing center, training facilities and all other corporate functions.
 
     The Company's other primary facility is located in Las Colinas, near
Dallas, Texas. This 15,300 square foot leased facility, which became operational
in October 1994, currently handles approximately one-third of the Company's data
processing needs and serves as a backup data processing facility.
 
     The Company also leases eight other facilities in Houston, Orlando,
Atlanta, Phoenix, Chicago, Washington, D.C./Baltimore and Denver that serve as
sales offices. These offices are typically staffed by six to eight sales
associates and a district sales manager.
 
   
     The Company believes that its facilities (certain portions of which have
recently been completed) are adequate for the purposes for which they are
intended and that its headquarters have sufficient additional capacity to
accommodate the Company's foreseeable expansion plan.
    
 
LEGAL PROCEEDINGS
 
     The Company is not a party to any material pending legal proceedings other
than ordinary routine litigation incidental to its business that the Company
believes would not have a material adverse effect on its financial condition or
results of operations.

                              INDUSTRY REGULATION
 
INTRODUCTION
 
     The Company's operations are affected by numerous federal and state laws
relating to labor, tax and employment matters. By entering into a co-employer
relationship with employees who are assigned to work at client company locations
(sometimes referred to as "worksite employees"), the Company assumes certain
obligations and responsibilities of an employer under these federal and state
laws. Because many of these federal and state laws were enacted prior to the
development of nontraditional employment relationships, such as professional
employer, temporary employment and outsourcing arrangements, many of these laws
do not specifically address the obligations and responsibilities of
non-traditional employers. In addition, the definition of "employer" under these
laws is not uniform.
 
     Some governmental agencies that regulate employment and labor laws have
developed rules that specifically address labor and employment issues raised by
the relationship among PEOs, in general, and the Company, in particular, client
companies and worksite employees. This is particularly true in Texas where
management has worked with numerous regulatory agencies and was instrumental in
the ultimate passage of the Staff Leasing Services Licensing Act, an act which
formally recognized the PEO industry in Texas and resolved prior interpretive
disputes as to the status of PEOs. Existing regulations are relatively new and,
therefore, their interpretation and application by administrative agencies and
federal and state courts is limited or non-existent. The development of
additional regulations and interpretation of existing regulations can be
expected to evolve over time. While the Company cannot predict with certainty
the nature or direction of the development of federal, state and local
regulations, management will continue to pursue a proactive strategy of
educating administrative authorities as to the advantages of PEOs and achieving
regulation which appropriately accommodates their legitimate business function.
 
     Certain federal and state statutes and regulations use the terms "employee
leasing" or "staff leasing" to describe the arrangement among a PEO, such as the
Company, and its clients and worksite employees. The terms "employee leasing,"
"staff leasing" and "professional employer arrangements" are generally
synonymous in such contexts and describe the arrangements entered into by the
Company, its clients and worksite employees.
 
     As an employer, the Company is subject to all federal statutes and
regulations governing its employer-employee relationships. Subject to the issues
discussed below, the Company believes that its operations are in compliance in
all material respects with all applicable federal statutes and regulations.
 
EMPLOYEE BENEFIT PLANS
 
     The Company offers various employee benefit plans to its employees,
including its worksite employees. These employee benefit plans are treated by
the Company as constituting "single-employer" plans of the Company rather than
multiple employer plans. These plans include the 401(k) Plan (a profit-sharing
plan with a cash or deferred arrangement ("CODA") under Code Section 401(k) and
a matching contributions feature under Code Section 401(m)), a cafeteria plan
under Code Section 125, a group health plan, a group life insurance plan, a
group disability insurance plan, an educational assistance plan, an adoption
assistance program and an employee assistance plan. Generally, employee benefit
plans are subject to provisions of both the Code and the Employee Retirement
Income Security Act of 1974, as amended ("ERISA").
 
     Employer Status. In order to qualify for favorable tax treatment under the
Code, the plans must be established and maintained by an employer for the
exclusive benefit of its employees. Generally, an entity is an "employer" of
certain workers for federal employment tax purposes if an employment
relationship exists between the entity and the workers under the common law test
of employment. In addition, the officers of a corporation are deemed to be
employees of that corporation for federal employment tax purposes. The common
law test of employment, as applied by the IRS, involves an examination of
approximately 20 factors to ascertain whether an employment relationship exists
between a worker and a purported employer. That test is generally applied to
determine whether an individual is an independent contractor or an employee for
federal employment tax purposes and not to determine whether each of two or more
companies is a "co-employer."
 
                                       42
<PAGE>   46
 
Substantial weight is typically given to the question of whether the purported
employer has the right to direct and control the details of an individual's
work. Among the various categories of factors which appear to be considered more
important by the IRS are (1) the employer's degree of behavioral control (the
extent of instructions, training and the nature of the work), (2) the financial
control or the economic aspects of the relationship and (3) the intended
relationship of the parties (are employee benefits provided, intent as evidenced
by any contracts, permanency (that is, are services ongoing or for a project),
any penalties for discharge/termination, and the frequency of the business
activity).
 
     In 1992, the Company applied for and received a favorable determination
from the IRS regarding the qualified status of the 401(k) Plan. In that
application, the Company disclosed to the IRS that the Company is involved in
the business of leasing employees to recipient companies and that the 401(k)
Plan covered worksite employees who satisfied the plan's eligibility
requirements. However, the statement that the 401(k) Plan covered worksite
employees does not necessarily resolve the issue of who is the employer of those
employees for purposes of the 401(k) Plan.
 
     The Company amended and restated the 401(k) Plan on December 15, 1994.
Among other amendments, the Company added the matching contributions feature
under Code Section 401(m) to the plan. In March 1995, the Company submitted the
amended and restated 401(k) Plan to the IRS for a determination on its continued
tax qualified status. The amended and restated 401(k) Plan is currently under
review by the IRS. An IRS finding that the plan document merits tax qualified
status is a determination as to the plan's form only and would not preclude a
subsequent disqualification based on the plan's operation, including a finding
that certain worksite employees are not employees of the Company for 401(k) Plan
purposes.
 
     Separate from its review of the pending determination request, the IRS is
currently auditing the Company's 401(k) Plan for the 1993 plan year. Although
the audit is for the 1993 plan year, certain conclusions of the IRS would be
applicable to subsequent years as well. In addition, the IRS has established a
Market Segment Study Group on Employee Leasing for the purpose of identifying
specific compliance issues prevalent in certain segments of the PEO industry.
Approximately 70 PEOs, including the Company, have been randomly selected by the
IRS for audit pursuant to this program. One issue that has arisen from these
audits is the Industry Issue (whether a PEO can be a co-employer of worksite
employees, including officers and owners of client companies, for various
purposes under the Code, including participation in the PEO's 401(k) plan).
NAPEO and the Company are cooperating with the IRS in this study of the PEO
industry. With respect to the 401(k) Plan audit, the Company understands that
the IRS group conducting the audit intends to submit the Technical Advice
Request to the IRS National Office. The Company also understands that, with
respect to the Market Segment Study, the IRS is similarly referring to the
National Office the Industry Issue. The IRS audit group leader has advised the
Company that the finding of facts from the Company's audit will be submitted
with the group leader's conclusion that such a co-employer status is not
recognized under current tax law. If the Market Segment Study were to reach a
conclusion that is adverse to the PEO industry, there is an administrative
procedure available to appeal that conclusion. In addition to working with the
Market Segment Study, NAPEO is actively engaged in policy discussions with both
the Treasury Department and with members of Congress in an effort to reduce the
likelihood of unfavorable conclusions and to procure favorable legislation.
 
     Whether the National Office will address the Technical Advice Request
independently of the Industry Issue is unclear. The Company is not able to
predict either the timing or the nature of any conclusions that may be reached
by the IRS with respect to the 401(k) Plan audit or with respect to the
Technical Advice Request or the Market Segment Study Group and the ultimate
outcome of such conclusions. Further, the Company is unable to predict whether
the Treasury Department will issue a policy statement with respect to its
position on the issues or, if issued, whether such a statement would be
favorable to the Company. The Company intends to vigorously pursue a favorable
resolution of the issues through one or more of the following methods: the
audit-technical advice, the Market Segment Study process, the policy and
legislative efforts, and, if necessary, legal action. If, however, any of these
processes were to conclude that a PEO is not a co-employer of its worksite
employees and such conclusion were to ultimately prevail, worksite employees
could not continue to make salary deferral contributions to the 401(k) Plan or
pursuant to the Company's cafeteria plan or continue to participate in certain
other employee benefit plans of the Company. The Company believes that,
 
                                       43
<PAGE>   47
 
although unfavorable to the Company, a prospective application by the IRS of
such an adverse conclusion (that is, one applicable only to periods after such a
conclusion is reached) would not have a material adverse effect on its financial
position or results of operations, as the Company could continue to make
available similar benefit programs to its client companies at comparable cost to
the Company. However, if such conclusion were applied retroactively to
disqualify the 401(k) Plan for 1993 and subsequent years, employees' vested
account balances under the 401(k) Plan would become taxable, the Company would
lose its tax deductions to the extent its matching contributions were not
vested, the 401(k) Plan's trust would become a taxable trust and the Company
would be subject to liability with respect to its failure to withhold applicable
taxes with respect to certain contributions and trust earnings. Further, the
Company would be subject to liability, including penalties, with respect to its
cafeteria plan for the failure to withhold and pay taxes applicable to salary
deferral contributions by employees, including worksite employees. In such a
scenario, the Company also would face the risk of client dissatisfaction and
potential litigation. A retroactive application by the IRS of an adverse
conclusion would have a material adverse effect on the Company's financial
position and results of operations. While the Company believes that a
retroactive disqualification is unlikely, there can be no assurance as to the
ultimate resolution of these issues by the IRS.
 
   
     Additional 401(k) Plan Issues. In 1991 the Company engaged a third party
vendor to be the 401(k) Plan's record keeper and to perform the required annual
nondiscrimination tests for the plan. Each year such record keeper reported to
the Company that such nondiscrimination tests had been satisfied. However, in
August 1996 the 401(k) Plan's record keeper advised the Company that certain of
these tests had been performed incorrectly for prior years and, in fact, that
the 401(k) Plan had failed certain tests for the 1993, 1994 and 1995 plan years.
The Company has subsequently determined that the 401(k) Plan also failed a
nondiscrimination test for 1991, a closed year for tax purposes. At the time the
Company received such notice, the period in which the Company could voluntarily
"cure" an operational defect had lapsed for all such years, except 1995. With
respect to the 1995 year, the Company will cause the 401(k) Plan to refund the
required excess contributions and earnings thereon to affected highly
compensated participants, and the Company will pay an excise tax of
approximately $51,000. Because the 401(k) Plan is under a current IRS audit, the
IRS voluntary correction program for this type of operational defect is not
available to the Company for years prior to 1995. Accordingly, the Company
informed the IRS of the prior testing errors for each of 1991, 1993 and 1994 and
proposed a correction that consists of corrective contributions by the Company
to the 401(k) Plan with respect to these years and the payment by the Company of
the minimum penalty ($1,000) that the IRS is authorized to accept to resolve
this matter. The IRS responded that resolution of the nondiscrimination test is
premature until the National Office resolves the Technical Advice Request. The
Company has recorded a reserve during the third quarter of 1996 for amounts it
may ultimately be required to pay in connection with corrective action with
respect to the 401(k) Plan. The amount of such reserve is the Company's estimate
of the cost of corrective measures and penalties, although no assurance can be
given that the actual amount that the Company may ultimately be required to pay
will not substantially exceed the amount so reserved. Based on its preliminary
discussions with the IRS and its understanding of the settlement experience of
other companies with respect to similar matters, the Company does not believe
that the ultimate resolution of the nondiscrimination test issue will have a
material adverse effect on the Company's financial condition or results of
operations, although no assurance can be given by the Company because the
ultimate resolution of this matter will be determined in a negotiation process
with the IRS.
    
 
     In addition to the nondiscrimination test errors, the Company has
discovered that it failed to timely adopt a technical amendment to the 401(k)
Plan by year end 1995, which it has now adopted retroactively. The Company has,
however, determined that since January 1, 1995, the 401(k) Plan has been
operated as if such amendment had been effective. Resolution of this failure
also has been deferred by the IRS audit group until the National Office resolves
the Technical Advice Request. Although the Company does not believe that its
failure to timely adopt the technical amendment to the 401(k) Plan in 1995 will
have a material adverse effect on the Company's financial condition or results
of operations, no assurance can be given by the Company with respect to such
matter because its ultimate resolution will be determined in a negotiation
process with the IRS.
 
                                       44
<PAGE>   48
 
     ERISA Requirements. Employee pension and welfare benefit plans are also
governed by ERISA. ERISA defines "employer" as "any person acting directly as an
employer, or indirectly in the interest of an employer, in relation to an
employee benefit plan." ERISA defines the term "employee" as "any individual
employed by an employer." The United States Supreme Court has held that the
common law test of employment must be applied to determine whether an individual
is an employee or an independent contractor under ERISA. A definitive judicial
interpretation of "employer" in the context of a PEO or employee leasing
arrangement has not been established.
 
     If the Company were found not to be an employer for ERISA purposes, its
plans would not comply with ERISA. Further, as a result of such finding the
Company and its plans would not enjoy, with respect to worksite employees, the
preemption of state laws provided by ERISA and could be subject to varying state
laws and regulations, as well as to claims based upon state common laws. Even if
such a finding were made, however, the Company would not be materially adversely
affected because it could continue to make available similar benefits at
comparable cost.
 
     In addition to ERISA and the Code provisions discussed herein, issues
related to the relationship between the Company and its worksite employees may
also arise under other federal laws, including other federal income tax laws.
 
     Possible Multiple Employer Plan Treatment. The DOL issued an Advisory
Opinion in December 1995 to a staff leasing company advising that particular
company that its health plan, which covered worksite employees, was a multiple
employer plan, rather than a single employer plan. Because the Company believes
it is a co-employer of worksite employees, the Company views its group health
plan, which also covers worksite employees, to be a single employer plan.
However, if this DOL opinion were applied to the Company, it is possible,
although the Company believes it is unlikely, that the DOL would assert
penalties against the Company for having incorrectly filed annual reports
treating its plan as a single employer plan. Such a conclusion, if applied to
the other employee benefit plans that cover worksite employees, could result in
additional liabilities of the Company. The Company does not believe that any
such penalties will, individually or in the aggregate, be material. Further,
even if such a conclusion is reached, however, the Company believes that it
would continue to be able to make available comparable benefit programs to
client companies.
 
FEDERAL EMPLOYMENT TAXES
 
     The Company assumes responsibility and liability for the payment of federal
and state employment taxes with respect to wages and salaries paid to its
employees, including worksite employees. There are essentially three types of
federal employment tax obligations: (i) withholding of income tax requirements
governed by Code Section 3401, et seq.; (ii) obligations under FICA, governed by
Code Section 3101, et seq.; and (iii) obligations under the FUTA, governed by
Code Section 3301, et seq. Under these Code sections, employers have the
obligation to withhold and remit the employer portion and, where applicable, the
employee portion of these taxes.
 
     The Market Segment Study Group discussed above is examining, among other
issues, whether PEOs, such as the Company, are employers of worksite employees
under the Code provisions applicable to federal employment taxes and,
consequently, responsible for payment of employment taxes on wages and salaries
paid to such worksite employees.
 
     Code Section 3401, which applies to federal income tax withholding
requirements, contains an exception to the general common law test applied to
determine whether an entity is an "employer" for purposes of federal income tax
withholding. Section 3401(d)(1) states that if the person for whom services are
rendered does not have control of the payment of wages, the "employer" for this
purpose is the person having control of the payment of wages. The Treasury
regulations issued under Section 3401(d)(1) state that a third party can be
deemed to be the employer of workers under this section for income tax
withholding purposes where the person for whom services are rendered does not
have legal control of the payment of wages.
 
     While Section 3401(d)(1) has been examined by several courts, its ultimate
scope has not been delineated. Moreover, the IRS has to date relied extensively
on the common law test of employment in
 
                                       45

determining liability for failure to withhold. Accordingly, while the Company
believes that it can assume the client company's withholding obligations, in the
event the Company fails to meet these obligations the client company may be held
jointly and severally liable therefor. While this interpretive issue has not to
the Company's knowledge discouraged clients from enrolling with the Company,
there can be no assurance that a definitive adverse resolution of this issue
would not do so in the future. These interpretive uncertainties may also impact
the Company's ability to report employment taxes on its own account rather than
for the accounts of its clients.
 
STATE REGULATION
 
     TEXAS
 
     As an employer, the Company is subject to all Texas statutes and
regulations governing the employer-employee relationship. Subject to the
discussion below, the Company believes that its operations are in compliance in
all material respects with all applicable Texas statutes and regulations.
 
     Prior to 1993, the PEO industry was not regulated as an industry in Texas.
Various state agencies attempted to apply their statutory schemes to PEOs on a
case-by-case basis and the Company faced various challenges from both the Texas
Employment Commission and the State Board of Insurance of Texas. Each of these
challenges was resolved with the passage of Texas' PEO licensing act described
below.
 
     Staff Leasing Services Licensing Act. The Company was instrumental in
obtaining enactment of the Staff Leasing Services Licensing Act (the "Act"),
which now regulates and establishes a legal framework for PEOs in Texas. The
Act, which became effective on September 1, 1993, established a mandatory
licensing scheme for PEOs and expressly recognizes a licensee as the employer of
the assigned employee for purposes of the Texas Unemployment Compensation Act.
The Act also provides, to the extent governed by Texas law, that a licensee may
sponsor and maintain employee benefit plans for the benefit of assigned
employees. In addition, the Act not only provides that a licensee may elect to
obtain workers' compensation insurance coverage for its assigned employees but
also provides that, for workers' compensation insurance purposes, a licensee and
its client company are treated as co-employers. After February 28, 1994, it
became a class A misdemeanor to engage in PEO activities in Texas without a
license. In order to obtain a license, applicants must undergo a background
check, demonstrate a history of good standing with tax authorities and meet
certain capitalization requirements that increase with the number of worksite
employees employed. The Act specifies that the Texas Department of Licensing and
Regulation ("TDLR") is responsible for enforcement of the Act and TDLR has
adopted regulations under the Act. The Company believes that it is in compliance
with such regulations in all material respects.
 
     OTHER STATE REGULATION
 
     While many states do not explicitly regulate PEOs, 16 states have passed
laws that have licensing or registration requirements for PEOs and at least four
states are considering such regulation. Such laws vary from state to state but
generally provide for monitoring the fiscal responsibility of PEOs. In addition
to holding a license in Texas, Administaff holds licenses in Arkansas, Florida
and New Hampshire, has been registered or certified in Massachusetts, Minnesota,
New Mexico and Nevada, and has applied for licenses in Montana, Oregon, South
Carolina, Tennessee and Utah. Whether or not a state has licensing, registration
or certification requirements, the Company faces a number of other state and
local regulations that could impact its operations. The Company believes that
its prior experience with Texas regulatory authorities will be valuable in
surmounting regulatory obstacles or challenges it may face in the future.

                                   MANAGEMENT
 
     The Company's Board of Directors currently has nine members. In accordance
with the Certificate of Incorporation of the Company, the members of the Board
of Directors are divided into three classes and are elected for a term of office
expiring at the third succeeding annual stockholders' meeting following their
election to office or until a successor is duly elected and qualified. The
Certificate of Incorporation also provides that such classes shall be as nearly
equal in number as possible. The terms of office of the Class I, Class II and
Class III directors expire at the annual meeting of stockholders in 1999, 1997
and 1998, respectively.

option. In addition, pursuant to the Company's stock option plan each director
of the Company who is neither an employee of the Company or an employee,
director, officer, partner, principal or affiliate of Texas Growth Fund, Pyramid

options to purchase 7,500 shares of Common Stock, which will vest one-third on
each anniversary of the date of grant. In addition, following each annual
meeting of the Company's stockholders, each such outside director will receive
an annual grant of options to purchase an additional 2,500 shares of Common
Stock, all of which are fully vested on the date of grant. The exercise price of
all such options is the fair market value at the time the options are granted.
Options to purchase a total of 7,500 shares of Common Stock have been granted
under such arrangement to Ms. Levinson. Directors who are employees of the
Company or affiliates of Texas Growth Fund or Pyramid Ventures, Inc. receive no
compensation for their services as directors.

STOCK OPTION PLAN
 
     In April 1995, the Company established the 1995 Administaff Employee Stock
Option Plan. At the annual meeting of the Company's stockholders held in April
1996, the Company's stockholders approved an amendment and restatement of such
plan to provide for automatic grants of options to non-employee directors (the
plan, as so amended and restated is referred to as the "Stock Option Plan").
Pursuant to the Stock Option Plan options may be granted to eligible employees
of the Company or its subsidiaries for the purchase of an aggregate of 357,957
shares of Common Stock of the Company. Stock options granted under the Stock
Option Plan are intended to qualify as "incentive stock options" within the
meaning of Section 422 of the Code. The purpose of the Stock Option Plan is to
further the growth and development of the Company and its subsidiaries by
providing, through ownership of stock of the Company, an incentive to employees
of the Company and its subsidiaries to increase such persons' interests in the
Company's welfare and to encourage them to continue their services to the
Company and its subsidiaries.
 
     In addition, the Stock Option Plan authorizes grants of nonqualified
options to directors of the Company, other than any director who is also an
employee of the Company or an affiliate or an employee, director, officer or
principal of The Texas Growth Fund, Pyramid Ventures, Inc. or any of their
respective controlling persons. Each qualifying non-employee director will
receive options to purchase 7,500 shares of Common Stock on the date first
elected or appointed to the Board and an additional grant of options to purchase
2,500 shares of Common Stock as of each annual meeting of stockholders on which
the director continues to serve on the Board. On April 23, 1996 (the date the
Company's stockholders approved the amendment and restatement referred to
above), Ms. Levinson received options to purchase a total of 7,500 shares of
Common Stock. The exercise price for these director options will be the fair
market value of the stock on the date of grant and each option will have a term
of 10 years. The 7,500 share option grants will vest as to one-third of the
shares on each anniversary of the option's grant date, while the 2,500 share
option grants will be fully vested when granted. In addition, the options cannot
be exercised after the third anniversary of the date the director ceases to be a
member of the Board. The purpose of such grants to non-employee directors is to
provide a means whereby such persons may develop a source of proprietorship and
personal involvement in the Company, to encourage them to devote their best
efforts to the Company's success and to enhance the Company's ability to attract
and retain the services of highly capable individuals to serve as directors.
 
     The Stock Option Plan is administered by the Board of Directors. The Board
of Directors has the power to determine which eligible employees will receive
stock option rights, the timing and manner of the grant of
 
                                       50
<PAGE>   54
 
such rights, the exercise price, and the number of shares to be covered by and
all of the terms of the options. The Board of Directors may delegate any or all
of its administrative duties pertaining to the Stock Option Plan to a committee
(the "Committee") of not less than three individuals, at least two of whom shall
be members of the Board of Directors.
 
     Eligible employees under the Stock Option Plan are all employees, including
any officer who is an employee, of the Company or any of its subsidiaries.
Except for the automatic grants to non-employee directors described above, no
director of the Company is eligible to receive options under the Stock Option
Plan unless the granting of such options is approved by a majority of
disinterested directors which comprise a majority of the Board of Directors, or
by the Committee, all of whom must be disinterested directors. The term of any
option granted under the Stock Option Plan shall be determined by the Board of
Directors or the Committee; provided, however, that the term of any stock option
cannot exceed 10 years from the date of the grant, and any stock option granted
to an employee who possesses more than 10% of the total combined voting power of
all classes of stock of the Company or of its subsidiaries within the meaning of
Section 422(b)(6)of the Code must not be exercisable after the expiration of
five years from the date of grant. The exercise price per share of Common Stock
of options granted under the Stock Option Plan will be the fair market value of
a share of Common Stock on the date the option is granted, determined in good
faith by the Board of Directors or the Committee. Further, the exercise price of
any stock option granted to an employee who possesses more than 10% of the total
combined voting power of all classes of stock of the Company or of its
subsidiaries within the meaning of Section 422(b)(6) of the Code must be at
least 110% of the fair market value of the share at the time such option is
granted. The exercise price of any shares purchased pursuant to an option
granted under the Stock Option Plan shall be paid in full upon exercise of such
option in cash, or by check, or at the discretion of the Board of Directors or
the Committee.
 
     Unless sooner terminated by action of the Board of Directors in its
discretion, the Stock Option Plan will terminate on the tenth anniversary of its
effective date. The Stock Option Plan was originally approved by the Board of
Directors on April 24, 1995, and by the shareholders of the Company on April 25,
1995, and the amendment and restatement thereof was approved by the Board of
Directors and by the Company's shareholders in April 1996. Options granted under
the Stock Option Plan are not transferable except in the event of death and must
be exercised by the optionee within 10 years after the date the option is
granted or within three months following the date the optionee's employment with
the Company terminates for any reason. The Board of Directors or the Committee,
in its discretion, may set the term for any option granted under the Stock
Option Plan; provided, however, that the term of the option cannot extend for a
period longer than that permitted for the option to qualify as an "Incentive
Stock Option" under Section 422 of the Code. The Board of Directors and the
Committee have the authority to prescribe, upon the granting of options, the
vesting schedule under which such options will become exercisable by each
optionee and the conditions of any such exercise, including the events or
circumstances resulting in the acceleration of any vesting schedule applicable
to the purchase of shares pursuant to any grant under the Stock Option Plan.
 
     The Board of Directors may at any time terminate or amend the Stock Option
Plan; provided that no such amendment may adversely affect the rights of
optionees with regard to outstanding options. Further, no material amendment to
the Stock Option Plan, such as an increase in the total number of shares covered
by the Stock Option Plan, a change in the class of persons eligible to receive
options, a reduction in the exercise price of options, and extension of the
latest date upon which options may be exercised, shall be effective without
stockholder approval.
 
     In April 1995 the Company granted options to purchase 96,791 shares of
Common Stock to certain non-executive officer employees with an exercise price
of $6.00 per share, which have all vested, and in August 1995 the Company
granted options to purchase 241,431 shares of Common Stock to certain non-
executive employees at $13.50 per share, 20% of which vest each year for the
ensuing five year period. At September 30, 1996, 321,139 options were
outstanding pursuant to these grants, of which 141,661 were exercisable. No
options have been exercised pursuant to these grants through September 30, 1996.
 
RELATED PARTY TRANSACTIONS
 
     On May 13, 1994, the Company completed a financing (the "Financing")
whereby, in exchange for an aggregate investment of $4 million, the Company
issued to TGF (i) $4 million principal amount of
 
                                       51
<PAGE>   55
 
subordinated notes maturing five years from the date of issue carrying interest
of 13% per annum, and (ii) warrants to purchase 694,436 shares of Common Stock
(the "TGF Investment"). In connection with the TGF Investment, Robert V. Walsh,
a representative of TGF, became a member of the Board of Directors.
 
     The Financing also involved the issuance by the Company of 1,532,303 shares
of Common Stock to PVI at a purchase price of $2.61 per share, or an aggregate
of $4 million (the "PVI Investment"). In connection with the PVI Investment,
Paul S. Lattanzio, a representative of PVI, became a member of the Board of
Directors of the Company. Also in connection with the PVI Investment, PVI
acquired 606,667 shares of Common Stock of the Company from the following
existing stockholders in the respective amounts: McIntosh Charitable Remainder
Trust, 13,333 shares; the Reed Foundation, 10,000 shares; Gary F. Reed, 523,333
shares; Hammond Family Foundation, 20,000 shares; James W. Hammond, 20,000
shares; and Scott C. Hensel, 20,000 shares. James W. Hammond and Scott C. Hensel
are members of the Board of Directors and the McIntosh Charitable Remainder Unit
Trust and the Hammond Family Foundation are affiliates of members of the Board
of Directors. At the time of the PVI Investment, Gary F. Reed was a member of
the Board of Directors and the Reed Foundation was an affiliate of Mr. Reed.
 
     In connection with the PVI Investment and the TGF Investment, the Company,
TGF, PVI and certain holders of Common Stock entered into an Investor Agreement
(the "Investor Agreement") and a Voting Agreement (the "Voting Agreement"), each
dated May 13, 1994. Pursuant to the Investor Agreement, PVI has a right of first
refusal to purchase any equity securities issued by the Company other than those
issued pursuant to a registered public offering, employee compensation plan or
certain warrants held by TGF and Rauscher Pierce Refsnes, Inc. ("Rauscher"), or,
in certain instances, those issued after repurchase by the Company. In addition,
pursuant to the Voting Agreement, PVI has the right to elect at least one member
of the Company's Board of Directors. Both the right of first refusal and the
board seat provisions contained in the Investor Agreement and Voting Agreement,
respectively, terminate if and when PVI ceases to own either (i) four percent or
more of the outstanding Common Stock, on a fully diluted basis, or (ii) $10
million or more of Common Stock based on the average closing price of the Common
Stock for the 30 previous trading days.
 
     In June 1995, Richard G. Rawson, Chief Financial Officer and a director of
the Company, exercised options to purchase 448,667 shares of Common Stock at a
price of $0.75 per share. The purchase price was paid in cash by Mr. Rawson. In
connection with the exercise of the options, the Company entered into a loan
agreement with Mr. Rawson in the amount of $694,000, whereby the Company paid
certain federal income tax withholding requirements related to the stock option
exercise. The loan agreement called for an additional amount to be advanced to
Mr. Rawson in the event the ultimate tax liability resulting from the exercise
exceeds the statutory withholding requirements. In April 1996, an additional
$300,000 was loaned to Mr. Rawson pursuant to this provision of the agreement.
The loan is repayable in five years, accrues interest at 6.83% and is secured by
448,667 shares of Common Stock. See "Principal and Selling Stockholders."
 
     Mr. Rawson, James W. Hammond and Scott C. Hensel, each of whom is a
director, stockholder and officer of the Company, are the stockholders of
Technology and Business Consultants, Inc. ("TBC"), which has in the past
provided various equipment, supplies, and services to the Company. The Company
paid $40,000 in 1994 for such services and equipment from TBC. In addition, the
Company has an account receivable in the amount of $93,000 from TBC Orthopedics,
Inc., a venture established by TBC. This debt has been guaranteed by TBC.
 
     In April 1996, the Company entered into a settlement agreement relating to
litigation in which the Company and TBC were co-defendants. In accordance with
the settlement agreement, $285,000 was paid to the plaintiff. The Company paid
the entire amount of the settlement; however, TBC has agreed to reimburse the
Company for the entire amount of the settlement not recovered through the
Company's general liability insurance. In August 1996, the Company received
$113,000 pursuant to such coverage. The remaining $172,000 is expected to be
reimbursed by TBC prior to the end of 1996.
 
     In October 1996, the Company purchased various computer equipment from TBC
at a total cost of $209,000.
 
     BT Securities Inc., an affiliate of PVI, will participate in the
underwriting syndicate for this offering and will receive customary compensation
in connection with such participation.

                          DESCRIPTION OF CAPITAL STOCK
 
AUTHORIZED AND OUTSTANDING CAPITAL STOCK
 
     At the date hereof, the authorized capital stock of the Company is
80,000,000 shares, consisting of 60,000,000 shares of Common Stock of the
Company, par value $0.01 per share ("Common Stock"), and 20,000,000 shares of
Preferred Stock of the Company, par value $0.01 per share ("Preferred Stock").
The following summary is qualified in its entirety by reference to the Company's
Certificate of Incorporation (the "Charter") and Bylaws (the "Bylaws"), copies
of which are included as exhibits to the Registration Statement of which this
Prospectus is a part. All outstanding shares of Common Stock and Preferred Stock
are fully paid and non-assessable.
 
     Common Stock. The holders of Common Stock are entitled to dividends in such
amounts and at such times as may be declared by the Board of Directors out of
funds legally available therefor. See "Dividend Policy." Holders of the Common
Stock are entitled to one vote per share for the election of directors and other
corporate matters. In the event of liquidation, dissolution or winding up of the
Company, holders of Common Stock would be entitled to share ratably in all
assets of the Company available for distribution to the holders of Common Stock.
The Common Stock carries no preemptive rights. All outstanding shares of Common
Stock are, and the shares of Common Stock to be sold by the Company in this
offering when issued will be, duly authorized, validly issued, fully paid and
nonassessable.
 
     Preferred Stock. The Board of Directors is authorized to issue from time to
time, without stockholder authorization, in one or more designated series,
shares of preferred stock with such dividend, redemption, conversion and
exchange provisions as are provided in the particular series. Prior to the date
hereof, none of such shares have been issued. Except as by law expressly
provided, or except as may be provided by resolution of the Board of Directors,
the Preferred Stock shall have no right or power to vote on any question or in
any proceeding or to be represented at, or to receive notice of, any meeting of
stockholders of Administaff. The issuance of the Preferred Stock could have the
effect of delaying or preventing a change in control of the Company. The Board
of Directors has no present plans to issue any of the Preferred Stock.
 
PROVISIONS HAVING POSSIBLE ANTI-TAKEOVER EFFECT
 
     Statutory Provisions. Section 203 ("Section 203") of the General
Corporation Law of the State of Delaware (the "Delaware Act") restricts certain
transactions between a corporation organized under Delaware law (or its
majority-owned subsidiaries) and any person holding 15% or more of the
corporation's outstanding voting stock, together with the affiliates or
associates of such person (an "Interested Stockholder"). Section 203 generally
prohibits a publicly held Delaware corporation from engaging in the following
transactions with an Interested Stockholder, for a period of three years from
the date the stockholder becomes an Interested Stockholder (unless certain
conditions, described below, are met): (a) all mergers or consolidations, (b)
sales, leases, exchanges or other transfers of 10% or more of the aggregate
assets of the corporation, (c) issuances or transfers by the corporation of any
stock of the corporation which would have the effect of increasing the
Interested Stockholder's proportionate share of the stock of any class or series
of the corporation, (d) any other transaction which has the effect of increasing
the proportionate share of the stock of any class or series of the corporation
which is owned by the Interested Stockholder, and (e) receipt by the Interested
Stockholder of the benefit (except proportionately as a stockholder) of loans,
advances, guarantees, pledges or other financial benefits provided by the
corporation.
 
     The three-year ban does not apply if either the proposed transaction or the
transaction by which the Interested Stockholder became an Interested Stockholder
is approved by the board of directors of the corporation prior to the date such
stockholder becomes an Interested Stockholder. Additionally, an Interested
Stockholder may avoid the statutory restriction if, upon the consummation of the
transaction whereby such stockholder becomes an Interested Stockholder, the
stockholder owns at least 85% of the outstanding voting stock of the corporation
without regard to those shares owned by the corporation's officers and directors
or certain employee stock plans. Business combinations are also permitted within
the three-year period if approved by the board of directors and authorized at an
annual or special meeting of stockholders, by the
 
                                       55
<PAGE>   59
 
holders of at least 66 2/3% of the outstanding voting stock not owned by the
Interested Stockholder. In addition, any transaction is exempt from the
statutory ban if it is proposed at a time when the corporation has proposed, and
a majority of certain continuing directors of the corporation have approved, a
transaction with a party which is not an Interested Stockholder of the
corporation (or who becomes such with board approval) if the proposed
transaction involves (a) certain mergers or consolidations involving the
corporation, (b) a sale or other transfer of over 50% of the aggregate assets of
the corporation, or (c) a tender or exchange offer for 50% or more of the
outstanding voting stock of the corporation.
 
     Prior to the effective date of Section 203, a corporation, by action of its
board of directors, had the option of electing to exclude itself from the
coverage of Section 203. Since the effective date of such section, a corporation
may, at its option, exclude itself from the coverage of Section 203 by amending
its Certificate of Incorporation or Bylaws by action of its stockholders to
exempt itself from coverage, provided that such charter or bylaw amendment shall
not become effective until 12 months after the date it is adopted. The Company
has not adopted such a charter or bylaw amendment.
 
     Charter and Bylaw Provisions. The Board of Directors is divided into three
classes, designated Class I, Class II and Class III. Each class of directors
consists, as nearly as possible, of one-third of the total number of directors
constituting the entire Board of Directors. The Charter provides that the number
of directors will be fixed by, or in the manner provided in, the Bylaws. The
Bylaws provide that the number of directors may be fixed from time to time by
resolution of the Board of Directors, but will consist of not less than three
nor more than 15 members. The term for directors in Class I expires at the
annual meeting of stockholders to be held in 1999; the initial term for
directors in Class II expires at the annual meeting of stockholders to be held
in 1997; and the initial term for directors in Class III expires at the annual
meeting of stockholders to be held in 1998. A director of the Company may be
removed only for cause and only upon the affirmative vote of the holders of a
majority of the outstanding capital stock entitled to vote at an election of
directors.
 
     The Charter provides that the Company may, by action of its Board of
Directors, adopt a rights plan. The Company does not currently have a rights
plan in effect.
 
     The Charter provides that the Company may, by action of its Board of
Directors, provide for a sinking fund for the purchase or redemption of shares
of any series and specify the terms and conditions governing the operations of
any such fund. The Company does not currently have any such fund.
 
     The Bylaws provide that the Board of Directors shall fix the number of
directors and that a stockholder may nominate directors only if written notice
is delivered to the Company by such stockholder not less than 30 days nor more
than 60 days prior to the meeting or no later than ten days after the date of
notice by the Company of such meeting if such notice is given less than 40 days
in advance of the meeting. The Charter and the Bylaws also provide that any
newly created directorship resulting from an increase in the number of directors
or a vacancy on the Board of Directors shall be filled by vote of a majority of
the remaining directors then in office, even though less than a quorum. The
Bylaws also provide that special meetings of the stockholders may only be called
by the Board of Directors and the holders of not less than 25% of the Company's
voting stock and that the stockholders may not act by written consent. The
Charter provides that these provisions of the Charter and the Bylaws may not be
amended without the approval of at least 66 2/3% of the voting power of all
shares of the Company entitled to vote generally in the election of directors,
voting together as a single class.
 
     The foregoing provisions of the Charter and the Bylaws and of Section 203,
together with the ability of the Board of Directors to issue Preferred Stock
without further stockholder action, could delay or frustrate the removal of
incumbent directors or the assumption of control by the holder of a large block
of Common Stock even if such removal or assumption would be beneficial, in the
short term, to stockholders of the Company. The provisions could also discourage
or make more difficult a merger, tender offer or proxy contest even if such
event would be favorable to the interests of stockholders.

LIMITATION ON DIRECTORS AND OFFICERS LIABILITY
 
     The Delaware Act authorizes corporations to limit or eliminate the personal
liability of directors to corporations and their stockholders for monetary
damages for breach of directors fiduciary duty of care. The duty of care
requires that, when acting on behalf of the corporation, directors must exercise
an informed business judgment based on all material information reasonably
available to them. Absent the limitations authorized by such legislation,
directors are accountable to corporations and their stockholders for monetary
damages for conduct constituting gross negligence in the exercise of their duty
of care. Although the Delaware Act does not change directors' duty of care, it
enables corporations to limit available relief to equitable remedies such as
injunction or rescission. The Charter limits the liability of the Company's
directors 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
Delaware Act. Specifically, 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) under Section 174 of the Delaware Act or (iv) for any transaction
from which the director derived an improper personal benefit.
 
     The inclusion of this provision in the Charter may have the effect of
reducing the likelihood of derivative litigation against directors and may
discourage or deter stockholders or management from bringing a lawsuit against
directors for breach of their duty of care, even though such an action, if
successful, might otherwise have benefited the Company and its stockholders.
 
TRANSFER AGENT
 
     The Transfer Agent for the Common Stock is KeyCorp Shareholder Services,
Inc.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of this offering, there will be 13,377,329 shares of Common
Stock outstanding. All of the shares purchased in this offering will be freely
tradeable without registration or other restriction under the Securities Act of
1933, as amended (the "Securities Act"), except for any shares purchased by an
affiliate of the Company. All of the remaining shares of Common Stock
outstanding (the "Restricted Shares") may be sold only pursuant to an effective
registration statement filed by the Company or pursuant to an applicable
exemption, including an exemption under Rule 144 under the Securities Act.
 
     In general, Rule 144 provides that if a person (including an affiliate)
holds Restricted Shares (regardless of whether such person is the initial holder
or a subsequent holder of such shares), and if at least two years have elapsed
since the later of the date on which the Restricted Shares were issued or the
date that they were acquired from an affiliate, then such person is entitled to
sell within any three-month period a number of shares that does not exceed the
greater of 1% of the then outstanding shares of Common Stock or the average
weekly trading volume of such stock during the four calendar weeks preceding the
sale. After Restricted Shares are held for three years, a person who is not
deemed an "affiliate" of the Company would be entitled to sell such shares under
Rule 144 without regard to the volume limitations described above. As of
            , 1996, approximately           shares of Common Stock are currently
eligible for unrestricted sale under Rule 144. The balance of the shares of
Common Stock are available for sale subject to holding, volume and other
restrictions provided in Rule 144.
 
     PVI, the holder of 2,138,970 shares of Common Stock (the "PVI Shares"),
TGF, the holder of warrants to purchase 694,436 shares of Common Stock (the "TGF
Warrants"), and Rauscher, the holder of warrants to purchase 153,230 shares of
Common Stock, have certain rights to require the Company to register sales of
such shares, or shares acquired pursuant to such warrants, under the Securities
Act, subject to certain restrictions. If, subsequent to the consummation of this
offering, the Company proposes to register any of its securities under the
Securities Act, such holders are entitled to notice of such registration and to
include their shares in such registration with their expenses borne by the
Company, subject to the right of an underwriter participating in the offering to
limit the number of shares included in such registration. In addition, PVI and
 
                                       57
<PAGE>   61
 
TGF have the right to demand, on five occasions, that the Company file a
registration statement covering sales of their respective shares, and the
Company is obligated to pay the expenses of the first two of such registrations.
Upon completion of the offering, the Company plans to use a portion of the
proceeds of the offering to exercise its option to repurchase 348,945 of the PVI
Shares and its option to repurchase 173,609 of the TGF Warrants (or shares
acquired upon exercise thereof).
 
     The effect, if any, that future market sales of shares or the availability
of shares for sale will have on the prevailing market prices for the Common
Stock cannot be predicted. Nevertheless, sales of a substantial number of shares
in the public market could adversely affect prevailing market prices for the
Common Stock.
 
     The Company, its directors, officers and certain of its principal
stockholders holding in the aggregate shares of Common Stock have agreed that
they will not, without the prior written consent of the Representatives of the
Underwriters, agree to sell, contract to sell or otherwise dispose of any shares
of Common Stock or other securities of the Company for a period of 180 days
after the date of this Prospectus, except for the grant of stock options, or the
issuance of shares upon the exercise of options granted, under the Stock Option
Plan.

     The 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 committed to take
and pay for all of the shares of Common Stock offered hereby (other than those
shares covered by the over-allotment option described below) if any such shares
are taken.
 
     The Underwriters initially propose to offer part of the Common Stock
directly to the public at the public offering price set forth on the cover page
hereof and to certain dealers at a price that represents a concession not in
excess of $          per share under the public offering price. Any Underwriter
may allow, and such dealers may reallow, a concession not in excess of
$          a share to other Underwriters or to certain dealers. After the
initial offering of the shares of Common Stock, the offering price and other
selling terms may from time to time be varied by the Underwriters.
 
     The Selling Stockholders have granted the Underwriters an option,
exercisable for 30 days from the date of this Prospectus, to purchase up to an
additional 450,000 shares of Common Stock at the public offering price set forth
on the cover page hereof, less underwriting discounts and commissions. The
Underwriters may exercise such option to purchase solely for the purpose of
covering over-allotments, if any, incurred in the sale of the shares of Common
Stock 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 shares as the number set forth next to
such Underwriter's name in the preceding table bears to the total number of
shares of Common Stock offered by the Underwriters hereby.
 
   
     The Underwriters have informed the Company that they do not intend sales to
discretionary accounts to exceed five percent of the total number of shares of
Common Stock offered by them.
    
 
     The Company and the executive officers and directors of the Company and
certain other stockholders have agreed that, without the prior written consent
of Morgan Stanley & Co. Incorporated, they will not offer, sell, contract to
sell or otherwise dispose of any shares of Common Stock or any securities
convertible into or
 
                                       59
<PAGE>   63
 
exercisable or exchangeable for Common Stock, for a period of 180 days after the
date of this Prospectus, other than the shares of Common Stock offered hereby.
 
   
     Prior to the offering of Common Stock hereby, there has been no public
market for the Common Stock. The initial public offering price has been
determined by negotiations between the Company and the Underwriters. Among the
factors considered in determining the initial public offering price were the
future prospects of the Company and its industry in general, sales, earnings and
certain other financial and operating information of the Company in recent
periods, and the price-earnings ratios, price-sales ratios, market prices of
securities and certain financial and operating information of companies engaged
in activities similar to those of the Company.
    
 
     The NYSE has approved the Common Stock for listing, subject to official
notice of issuance, under the symbol "ASF." In order to meet one of the
requirements for listing the Common Stock on the NYSE, the Underwriters have
undertaken to sell lots of 100 or more shares to a minimum of 2,000 beneficial
holders.
 
     The Company and the Selling Stockholders have agreed to indemnify the
Underwriters against certain liabilities, including civil liabilities under the
Securities Act.
 
     BT Securities Inc., an affiliate of PVI, will participate in the
underwriting syndicate for this offering and will receive customary compensation
in connection with such participation.
 
                                 LEGAL MATTERS
 
     Certain legal matters in connection with the Common Stock being offered
hereby will be passed upon for the Company by Andrews & Kurth L.L.P., Houston,
Texas and for the Underwriters by Fulbright & Jaworski L.L.P., Houston, Texas.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
Administaff, Inc.
 
     We have audited the accompanying consolidated balance sheets of
Administaff, Inc., as of December 31, 1994 and 1995, and the related
consolidated statements of operations, stockholders' equity, and cash flows for
each of the three years in the period ended December 31, 1995. 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 consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Administaff, Inc., at December 31, 1994 and 1995, and the consolidated results
of its operations and its cash flows for each of the three years in the period
ended December 31, 1995 in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1995
 
1. ACCOUNTING POLICIES
 
  Description of Business
 
     Administaff, Inc. (the Company) is a professional employer organization
(PEO) that provides a comprehensive personnel management system which
encompasses a broad range of services, including benefits and payroll
administration, medical and workers' compensation programs, tax filings,
personnel records management, liability management, and other human resource
services to small to medium sized businesses in several strategically selected
markets. The Company operates primarily in the State of Texas.
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of Administaff,
Inc., and its wholly owned subsidiaries. Intercompany accounts and transactions
have been eliminated in consolidation.
 
     During 1995, the Company completed a reorganization by which it formed
Administaff of Delaware, Inc., (the Holding Company) as a wholly-owned
subsidiary of the Company. At the same time, the Holding Company formed a
wholly-owned subsidiary, Administaff of Texas, Inc. into which the Company
merged. The stockholders of the Company exchanged shares of Common Stock of the
Company for shares of Common Stock of the Holding Company at a ratio of 3 for 2.
All outstanding warrants and stock options of the Company were exchanged for
warrants and stock options of the Holding Company at the same exchange ratio.
The Holding Company then changed its name to Administaff, Inc. The
reorganization had no effect on net income. Share amounts in the consolidated
financial statements and accompanying notes have been restated to reflect the
reorganization into the Holding Company (herein referred to as the Company) and
the 3-for-2 exchange.
 
  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.
 
  Impairment of Long-Lived Assets
 
     In March 1995, Statement of Financial Accounting Standards (SFAS) No. 121,
Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of, was issued. This Statement requires impairment losses to be
recorded on long-lived assets used in operations when indicators of impairment
are present and the undiscounted cash flows estimated to be generated by those
assets are less than the assets' carrying amount. SFAS No. 121 also addresses
the accounting for long-lived assets that are expected to be disposed of. The
Company will adopt SFAS No. 121 in the first quarter of 1996 and, based on
current circumstances, believes there will be no effect on the consolidated
financial statements from such adoption.
 
  Cash and Cash Equivalents
 
     Cash and cash equivalents include bank deposits and short-term investments
with original maturities of three months or less when purchased.
 
  Cash and Cash Equivalents -- Restricted
 
     Prior to October 1995, the Company had cash equivalents which were
restricted from withdrawal under the terms of a security agreement with a bank
whereby the Company agreed to maintain a deposit account

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
securing the bank's exposure to the return of client payments due to
insufficient funds. At December 31, 1995, no such restrictions are in place.
 
  Marketable Securities
 
     The Company's marketable securities are classified as available-for-sale
and are carried at amortized cost which approximates fair value. Unrealized
gains and losses, if any, are accumulated as a separate component of
stockholders' equity. Realized gains and losses are computed based on specific
identification of the securities sold.
 
  Property and Equipment
 
     Property and equipment is recorded at cost. Maintenance and repairs are
charged to expense as incurred; renewals and betterments are capitalized. The
cost of property and equipment sold or otherwise retired and the accumulated
depreciation applicable thereto are eliminated from the accounts, and the
resulting profit or loss is reflected in operations.
 
     The cost of property and equipment is depreciated over the estimated useful
lives of the related assets using the straight-line method. The estimated useful
lives of property and equipment for purposes of computing depreciation are as
follows:

    Buildings and improvements..............................  7-30 years
    Computer equipment......................................  5-10 years

</TABLE>
 
Construction in progress at December 31, 1995 includes costs incurred in
connection with the construction of an additional corporate facility which was
completed in February 1996. Interest capitalized in connection with this project
was $74,000 in 1995.
 
  PEO Service Fees and Worksite Employee Payroll Costs
 
     The Company's revenues consist of service fees paid by its clients under
its Client Service Agreements. In consideration for payment of such service
fees, the Company agrees to pay the following direct costs associated with the
worksite employees: (i) salaries and wages, (ii) employment related taxes, (iii)
employee benefit plan premiums and (iv) workers' compensation insurance
premiums. The Company accounts for PEO service fees and the related direct
payroll costs using the accrual method. Under the accrual method, PEO service
fees relating to worksite employees with earned but unpaid wages at the end of
each period are recognized as unbilled revenues and the related direct payroll
costs for such wages are accrued as a liability during the period in which wages
are earned by the worksite employee. Subsequent to the end of each period, such
wages are paid and the related PEO service fees are billed. Unbilled receivables
at December 31, 1994 and 1995 are net of prepayments received prior to year end
of $1,252,000 and $661,000, respectively.
 
  Intangible Assets
 
     Intangible assets include software development costs, referral fee costs
paid for the enrollment of certain clients previously with an unrelated PEO, and
organizational costs. Software development costs include costs related to
designing and installing the Company's computerized payroll system and are being
amortized using the straight-line over a period of five years.
 
     The referral fee costs are being amortized over a period of five years,
which is the expected retention period for the related clients.

                               ADMINISTAFF, INC.
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Certain costs incurred in the initial formation of the Company were
capitalized. As of December 31, 1995, such costs were fully amortized.
 
  Accrued Workers' Compensation Claims
 
     The Company has, from time to time, been insured under various types of
workers' compensation policies. These have included a retrospective rating plan,
whereby monthly premiums were paid to the insurance carrier based on estimated
actual losses plus an administrative fee; a high deductible paid loss plan,
whereby monthly premiums were paid based on a $500,000 deductible per
occurrence; and a guaranteed cost plan whereby monthly premiums are paid for
complete coverage of all claims under the policy.
 
     Accrued workers' compensation claims relate to policies in place prior to
November 1, 1994 and are based on an estimate of reported and unreported losses,
net of amounts covered under the applicable insurance policy, for injuries
occurring on or before the balance sheet date. The loss estimates are based on
several factors including the Company's current experience, relative health care
costs, regional influences and other factors. While estimated losses may not be
paid for several years, an accrual for outstanding claims on the retrospective
rating plan and high deductible paid loss plan is maintained using the estimated
net present value of such claims calculated at an interest rate of 6.25%, with
changes in the accrual reflected as a component of direct costs in the period of
the change. These estimates are continually reviewed and any adjustments are
reflected in operations as they become known.
 
   
     In September 1995, the Company settled the remaining outstanding claims
under certain retrospective rating workers' compensation policies in effect in
prior years resulting in a reduction in workers' compensation costs of $1
million in 1995. This amount is included as a reduction in Direct costs:
Benefits and payroll taxes on the Consolidated Statements of Operations. In
exchange for transferring the responsibility for all remaining claims under such
policies, the Company paid the insurer $232,000. Prior to the settlement, the
Company had accrued workers' compensation claims of approximately $1.2 million
related to the settled policies.
    
 
     Beginning November 1, 1994, the Company has been insured under a guaranteed
cost workers' compensation policy which is currently in effect through October
31, 1996.
 
  Stock Based Compensation
 
     The Company accounts for stock based compensation arrangements under the
provisions of Accounting Principles Board Opinion No. 25, "Accounting for Stock
Issued to Employees," and intends to continue to do so.
 
  Advertising
 
     The Company expenses all advertising costs as incurred.
 
  Income Taxes
 
     The Company uses the liability method in accounting for income taxes. Under
this method, deferred tax assets and liabilities are determined based on
differences between financial reporting and income tax carrying amounts of
assets and liabilities and are measured using the enacted tax rates and laws
that will be in effect when the differences are expected to reverse.
 
  Per Share Information
 
     Per share amounts have been computed based on the weighted average number
of common shares and common stock equivalents outstanding during the respective
periods. Common stock equivalent shares consist of the incremental shares
issuable upon the exercise of stock options and warrants (using the treasury
stock or

if-converted method where applicable). Shares for which stock options were
granted within a twelve month period prior to an initial public offering are
treated as outstanding for all periods presented. Therefore, shares for which
options were granted subsequent to September 1994 have been considered as having
been outstanding for purposes of the calculation (using the treasury stock
method with the offering price used for fair market value) for all periods
presented. Common stock equivalent shares from stock options and warrants
granted prior to the twelve months preceding the initial public offering are
excluded from computations if their effect is antidilutive.
 
  Reclassifications
 
     Certain prior year amounts have been reclassified to conform to the 1995
presentation.

     In May 1994, the Company issued $4,000,000 in subordinated notes to a
private investor pursuant to a Securities Purchase Agreement. The subordinated
notes mature in May 1999 and contain certain optional prepayment clauses.
Interest accrues at the annual rate of 13% and is payable quarterly. The
subordinated notes are subordinate to the $610,000 note payable to bank. The
Securities Purchase Agreement provides the Company with the right of first
refusal to repurchase the subordinated notes in the event of a proposed transfer
of the subordinated notes by the investor. In connection with the subordinated
notes, the Company issued the investor warrants to purchase 694,436 shares of
common stock. In connection with this transaction, a representative of the
investor became a member of the Board of Directors of the Company. Interest
expense includes $325,000 and $520,000 in 1994 and 1995, respectively, related

     In October 1995, the Company's wholly-owned subsidiary, Administaff of
Texas, Inc. (AT), entered into a revolving credit agreement with The First
National Bank of Chicago, as agent, pursuant to which the lenders that are
parties thereto have agreed to advance funds to AT on a revolving basis in an
amount not to exceed $10 million for general corporate purposes. Such agreement
includes an agreement to issue standby letters of credit in an amount not to
exceed a sublimit of $5 million. Borrowings under the agreement will bear
interest at rates based on the bank's Corporate Base Rate or LIBOR plus an
applicable margin at the time of borrowing. The Company is a guarantor under the
agreement. The agreement requires the Company to maintain certain specified
financial ratios and contains other restrictions customary in lending
transactions of this type, including a prohibition on the declaration and
payment of dividends if a default exists or, after giving effect to such
dividend, would exist under such agreement. As of December 31, 1995 there is no
amount outstanding under the agreement and AT has $10 million available for
borrowings under the agreement.

paid in prior years to ensure recoverability.

5. STOCKHOLDERS' EQUITY
 
     In May 1994, the Company entered into a Stock Purchase Agreement with a
private investor whereby the investor purchased 1,532,303 shares of common stock
from the Company at a price of $2.61 per share. The Company realized net
proceeds of $3,571,000. The Stock Purchase Agreement contains various
restrictive covenants and provides the investor with certain antidilution
privileges. An Investor Agreement provides the Company with the right of first
refusal to repurchase the shares in the event of a proposed transfer of the
shares by the investor. In addition, the Investor Agreement provides the Company
with an option to repurchase up to 348,945 of the shares through June 1999 at
prices beginning at $5.73 per share through June 1997 and escalating annually
thereafter. See Note 11.
 
   
     In connection with the issuance of $4,000,000 in subordinated notes, the
Company issued warrants to purchase 694,436 shares of common stock at a price of
$2.61 per share to the noteholder. The Investor Agreement provides the Company
with an option to repurchase 173,609 of the warrants or related shares through
June 1999 at a price of $5.73 per warrant or related share less $2.61 per
warrant if not yet exercised, through June 1997 and escalating annually
thereafter. The holder of the subordinated notes may elect to exercise a portion
or all of the warrants at the exercise price as a reduction of the outstanding
balance of the subordinated notes. The warrants are exercisable through May 13,
2001 and contain certain antidilution provisions. See Note 11.
    
 
     The Investor Agreement also provides the holders of the shares of common
stock sold pursuant to the Stock Purchase Agreement and the common stock
purchase warrants issued in connection with the subordinated notes with the
right, subject to certain conditions, to require the Company to repurchase all
or any portion of the shares and warrants at a price to be calculated in
accordance with the Investor Agreement. This right becomes partially exercisable
in November 1998 and fully exercisable in November 2002 and terminates upon a
qualified public offering as defined in the Stock Purchase Agreement.
 
     In connection with the Stock Purchase Agreement and the subordinated notes,
the Company issued warrants to purchase 153,230 shares of common stock to a
third party as partial payment of fees related to the transactions. The warrants
are exercisable through June 1999 at prices commencing at $2.61 per share with
annual escalations to $5.42 per share for the final year. The warrants contain
certain antidilution provisions.
 
     During 1992, the Company granted options to an officer/director to purchase
an additional 448,667 shares of common stock at a price of $.75 per share. These
options were exercised in 1995. During 1993, the Company granted options to an
employee to purchase 40,000 shares of common stock at a price of $1.50 per
share. These options were exercised in 1995.
 
     There have been no outstanding warrants or options cancelled through
December 31, 1995.
 
     During 1993, the Company retired all of its outstanding 10% nonvoting,
convertible preferred stock. The Company paid $49,500 for 450 of the preferred
shares and issued 10,600 shares of its common stock in exchange for 530
preferred shares.

6. OPERATING LEASES
 
     The Company leases various furniture, equipment, and office facilities
under operating leases. Most of the leases contain purchase and/or renewal
options at fair market and fair rental value, respectively. Rental expense
relating to all operating leases was $638,000, $905,000 and $1,126,000 in 1993,
1994 and 1995, respectively. At December 31, 1995, future minimum rental
payments under noncancelable operating leases are as follows (in thousands):

7. EMPLOYEE SAVINGS PLAN
 
     The Company has adopted a 401(k) profit sharing plan (the Plan) for the
benefit of all eligible employees as defined in the plan agreement. The Plan is
a defined-contribution plan to which eligible employees may make contributions,
on a before-tax basis, of from 1% to 20% of their compensation during each year
while they are a plan participant. Under the Plan, employee salary deferral
contributions are limited to amounts established by tax laws. Participants are
at all times fully vested in their salary deferral contributions to the Plan and
the earnings thereon. All amounts contributed pursuant to the Plan are held in a
trust and invested, pursuant to the participant's election, in one or more
investment funds offered by a third party record keeper.
 
     Employees are eligible to participate in the plan on the entry date
coincident with or next following age 21 and upon completion of at least 1,000
hours of service in a consecutive 12-month period. Highly compensated employees
assigned to clients which have less than 100% of their workforce employed by the
Company are not eligible to participate. Entry dates are the first day of each
calendar month. Service with a client company is credited for eligibility and
vesting purposes under the plan.
 
   
     Effective June 1, 1994 the plan was amended to add the option of offering
matching contributions to certain worksite employees under Section 401(m) of the
Internal Revenue Code (the "Code"). The Company does not make matching
contributions to the plan for its corporate employees. Under this option, client
companies may elect to participate in the matching program, pursuant to which
the client companies contribute 50% of an employee's contributions up to 6% of
the employee's compensation each pay period. Participants vest in these matching
contributions on a graduated basis over five years with 20% vesting after one
year of service and 100% vesting after five years of service. For employees
participating in the matching program, the maximum salary deferral contribution
is 17% rather than 20%. In addition, participants shall be fully vested in these
matching contributions upon normal retirement (i.e., attainment of age 65) or
death. Total matching contributions related to worksite employees for the year
ended December 31, 1994 and 1995 were $41,000 and $420,000, respectively (none
in 1993), all of which were reimbursed to the Company by the client companies.
    
 
   
8. RELATED PARTY TRANSACTIONS
    
 
     Accounts receivable from related parties at December 31, 1994 and 1995
includes $93,000 from a company in which three of the directors of the Company
own a minority interest. Accounts receivable from related parties also includes
$156,000 and $627,000 from employees of the Company at December 31, 1994 and
1995, respectively.

     Three of the Company's stockholders and officers are the stockholders of
Technology and Business Consultants, Inc. ("TBC"), an entity which has provided
various equipment, supplies, and services to the Company. The Company paid
$754,000 and $40,000 in 1993 and 1994, respectively for such services and
equipment from TBC (none in 1995). Such costs are included primarily as a
component of general and administrative expenses.
 
     In June 1995, an officer of the Company exercised options to purchase
448,667 shares of common stock at a price of $0.75 per share. The purchase price
was paid in cash by the officer. In connection with the exercise of the options,
the Company entered into a loan agreement with the officer, whereby the Company
paid certain federal income tax withholding requirements related to the stock
option exercise on behalf of the officer in the amount of $694,000. The loan
agreement calls for an additional amount to be advanced to the officer in the
event the ultimate tax liability resulting from the exercise exceeds the
statutory withholding requirements. The loan is repayable in five years, accrues
interest at 6.83%, and is secured by 448,667 shares of the Company's common
stock.
 
     In September 1995, an employee of the Company exercised options to purchase
40,000 shares of common stock at a price of $1.50 per share. The purchase price
was paid in cash by the employee. In connection with the exercise of the
options, the Company entered into a loan agreement with the employee, whereby
the Company paid certain federal income tax withholding requirements related to
the stock option exercise on behalf of the employee in the amount of $141,000.
The loan agreements calls for an additional amount to be advanced to the
employee in the event the ultimate tax liability resulting from the exercise
exceeds the statutory withholding requirements. The loan is repayable in five
years, accrues interest at 6.83%, and is secured by 40,000 shares of the
Company's common stock.
 
9. COMMITMENTS AND CONTINGENCIES
 
     The Company's 401(k) Plan for the year ended December 31, 1993 is currently
under audit by the Internal Revenue Service ("IRS"). The Company understands
that one of the issues under review is the relationship of the Company to
certain worksite employees and the Company's status as their employer for 401(k)
Plan purposes. If the IRS concludes that the Company is not the "employer" of
certain worksite employees for purposes of the Code, worksite employees could
not continue to make salary deferral contributions to the 401(k) Plan or
continue to participate in certain other employee benefit plans of the Company,
including the Company's cafeteria plan. The Company believes that, although
unfavorable to the Company, a prospective application of such a conclusion would
not have a material adverse effect on its financial position or results of
operations. If such conclusion were applied retroactively, however, employees'
vested account balances would become taxable, the Company would lose its tax
deduction to the extent its matching contributions were not vested, the plan's
trust would become a taxable trust, and the Company could be subject to
liability with respect to its failure to withhold income and payroll taxes in
respect of such contributions and trust earnings thereon. In addition, the
Company could be subject to liability for failure to withhold applicable taxes
under certain other employee benefit plans in which worksite employees
participate. In such a scenario, the Company would also face the risk of client
dissatisfaction as well as potential litigation. While the ultimate outcome of
the audit is unknown, the Company believes that a retroactive application is
unlikely. The Company also believes that a prospective application of an
unfavorable outcome will not have a material adverse effect on the Company's
consolidated financial position or results of operations.
 
     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 adverse effect on the Company's consolidated
financial position or results of operations.
 
     The Company had outstanding letters of credit aggregating $4,666,000 at
December 31, 1994 (none at December 31, 1995).

10. EMPLOYEE STOCK OPTION PLAN
 
     In April 1995, the Company established the 1995 Administaff Employee Stock
Option Plan (the "Stock Option Plan"), pursuant to which options may be granted
to eligible employees of the Company or its subsidiaries for the purchase of an
aggregate of 357,957 shares of Common Stock of the Company. Stock options
granted under the Stock Option Plan are intended generally to qualify as
"incentive stock options" within the meaning of Section 422 of the Code. The
purpose of the Stock Option Plan is to further the growth and development of the
Company and its subsidiaries by providing, through ownership of stock of the
Company, an incentive to employees of the Company and its subsidiaries to
increase such persons' interests in the Company's welfare and to encourage them
to continue their services to the Company and its subsidiaries.
 
     The Stock Option Plan is administered by the Board of Directors (the
"Board"). The Board has the power to determine which eligible employees will
receive stock option rights, the timing and manner of the grant of such rights,
the exercise price, and the number of shares to be covered by and all of the
terms of the options. The Board may at any time terminate or amend the Stock
Option Plan; provided that no such amendment may adversely affect the rights of
optionees with regard to outstanding options. Further, no material amendment to
the Stock Option Plan, such as an increase in the total number of shares covered
by the Stock Option Plan, a change in the class of persons eligible to receive
options, a reduction in the exercise price of options, and extension of the
latest date upon which options may be exercised, shall be effective without
stockholder approval.
 
     In April 1995, the Board granted options to purchase 96,791 shares of
common stock at a price of $6.00 per share to certain non-management employees.
In August 1995, the Board granted options to purchase 241,431 shares of common
stock at a price of $13.50 per share to certain non-management employees. The
April grants are primarily fully vested, except for 9,013 shares which vest in
1996. The August grants vest at 20% per year over a five year period from the
date of grant. At December 31, 1995, 87,778 shares are exercisable pursuant to
the April grants. Through December 31, 1995, no options have been exercised
pursuant to these grants.
 
11. INITIAL PUBLIC OFFERING
 
     The Company filed a registration statement with the Securities and Exchange
Commission ("SEC") in September 1995 to register the sale of up to 3,000,000
shares of its common stock. The Company intends to use the net proceeds of the
sale to support expansion of the Company's operations including the opening of
new geographic markets, further penetration of existing markets by opening new
sales offices and, as opportunities arise, expansion of the Company's client
base in new or existing markets through acquisitions. A portion of the proceeds
will also be used to repay certain outstanding indebtedness, including the
subordinated notes, and to exercise certain options to repurchase 348,945 shares
of common stock and 173,609 warrants to purchase common stock. See Note 5.
 
     In connection with the preparation of consolidated financial statements to
be filed with the SEC, the Company elected to restate its financial statements
for certain previously reported accounting changes made in 1994 and 1993.
Accordingly, the accompanying consolidated financial statements and related
notes reflect this restatement. See Note 12.
 
     As of December 31, 1995, the Company remains in registration with the SEC
and the timetable for completion of the proposed offering is uncertain. The
Company has incurred costs totaling $745,000 through December 31, 1995 related
to the offering which are included in prepaid expenses on the consolidated
balance sheet. Upon consummation of the offering, such costs will be reflected
as a reduction to stockholders' equity.
 
     Supplemental net income per share is $0.16 for the year ended December 31,
1995 and is determined by adding back the interest expense, net of income taxes,
associated with the debt which will be retired by the proceeds of the offering
to net income. The number of shares outstanding used in calculating supplemental
net

income per share was the weighted average common shares outstanding after giving
effect to the estimated number of shares that would be required to be sold in
the offering to repay the debt and to repurchase the common stock and warrants.
 
12. ACCOUNTING CHANGES
 
     As reflected in its previously issued financial statements for 1994, the
Company changed its method of accounting for client enrollment costs and changed
its method of accounting for PEO service fees and worksite employee payroll
costs and in 1993 the Company changed its method of accounting for income taxes
in accordance with Statement of Financial Accounting Standards ("SFAS") No. 109.
In connection with the proposed initial public offering of the Company's common
stock, the Company elected to retroactively restate its financial statements for
these changes effective at the date of its inception.
 
  Deferred Client Enrollment Costs
 
     The Company changed its method of accounting for certain costs related to
acquiring new business, including advertising, review, quotation, and enrollment
expenses that vary with and are primarily related to the enrollment of new
clients, from the deferral method to the expense method. Under the expense
method, all such costs, including all advertising costs, are charged to expense
as incurred. Previously, under the deferral method, all such costs were deferred
and amortized using the straight-line method over a period of five years. The
new method of accounting was adopted partially to comply with the requirements
of Statement of Position 93-7 which requires all nondirect advertising costs to
be expensed when incurred. Such expenses were a significant portion of the costs
which were previously deferred. In addition, as the Company has grown, other
enrollment costs have become less material as a component of operating expenses.
As a result, the Company believes that expensing all enrollment costs will
result in a more accurate matching of costs and revenues.
 
  Accrual of PEO Service Fees and Worksite Employee Payroll Costs
 
     The Company changed its method of accounting for PEO service fees and the
related direct payroll costs to the accrual method. Under the accrual method,
PEO service fees are recognized as unbilled revenue and the related direct
payroll costs are accrued as a liability during the period in which wages are
earned by the worksite employee. Previously, the Company recorded the PEO
service fees and direct payroll costs in the period in which the payroll was
disbursed. The new method of accounting for these fees and expenses was adopted
to comply with the accrual method of accounting for revenues and expenses
required by generally accepted accounting principles, for which the difference
was not previously material to the financial position or results of operations
of the Company.
 
  Income Taxes
 
     Effective January 1, 1993, the Company adopted SFAS No. 109, "Accounting
for Income Taxes." As permitted, prior years financial statements have been
restated.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
1. BASIS OF PRESENTATION
 
     Administaff, Inc. (the Company) is a professional employer organization
(PEO) that provides a comprehensive personnel management system which
encompasses a broad range of services, including benefits and payroll
administration, medical and workers' compensation programs, tax filings,
personnel records management, liability management, and other human resource
services to small to medium sized businesses in several strategically selected
markets.
 
     The consolidated financial statements include the accounts of Administaff,
Inc. and its wholly owned subsidiaries. Intercompany accounts and transactions
have been eliminated.
 
     During 1995, the Company completed a reorganization by which it formed
Administaff of Delaware, Inc. (the Holding Company) as a wholly-owned subsidiary
of the Company. At the same time, the Holding Company formed a wholly-owned
subsidiary, Administaff of Texas, Inc. into which the Company merged. The
stockholders of the Company exchanged shares of common stock of the Company for
shares of common stock of the Holding Company at a ratio of 3-for-2. All
outstanding warrants and stock options of the Company were exchanged for
warrants and stock options of the Holding Company at the same exchange ratio.
The Holding Company then changed its name to Administaff, Inc. The
reorganization had no effect on net income. Share amounts in the consolidated
financial statements and accompanying notes have been restated to reflect the
3-for-2 exchange.
 
     The Company's consolidated balance sheet at September 30, 1996 and the
consolidated statements of operations, cash flows and stockholders' equity for
the interim periods ended September 30, 1996 and September 30, 1995 have been
prepared by the Company without audit. In the opinion of management, all
adjustments, consisting only of normal recurring adjustments, necessary to
present fairly the consolidated financial position, results of operations and
cash flows have been made. The results of operations for the interim periods are
not necessarily indicative of the operating results for a full year or of future
operations.
 
     Per share amounts have been computed based on the weighted average number
of common shares and common stock equivalents outstanding during the respective
periods. Common stock equivalent shares consist of the incremental shares
issuable upon the exercise of stock options and warrants (using the treasury
stock or the if-converted method where applicable). Shares for which stock
options were granted within a twelve month period prior to an initial public
offering are treated as outstanding for all periods presented. Therefore, shares
for which options were granted subsequent to September 1994 have been considered
as having been outstanding for purposes of the calculation (using the treasury
stock method with the offering price used for fair market value) for all periods
presented. Common stock equivalent shares from stock options and warrants
granted prior to twelve months preceding the initial public offering are
excluded from computations if their effect is antidilutive.
 
     Supplemental net income per share is $0.14 for the nine months ended
September 30, 1996 and is determined by adding back the interest expense, net of
income taxes, associated with the debt which will be retired by the proceeds of
the offering, to the net income. The number of shares outstanding used in
calculating supplemental net income per share was the weighted average common
shares outstanding after giving effect to the estimated number of shares that
would be required to be sold in the offering to repay the debt and to repurchase
the common stock and warrants.
 
     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.
 
     Certain information and footnote disclosures normally included in financial
statements prepared in accordance with generally accepted accounting principles
have been condensed or omitted. The accompanying

     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) -- (CONTINUED)
 
consolidated financial statements should be read in conjunction with the
Company's audited consolidated financial statements for the year ended December
31, 1995.

     The subordinated notes and the $610,000 note payable require the Company to
maintain certain specified financial requirements and contain other restrictions
customary in lending transactions of this type. The Company has obtained a
waiver of the quick ratio covenant in both agreements (a requirement covering
two consecutive quarters) for the two quarters ended September 30, 1996. This
waiver cures any noncompliance with the covenant as of September 30, 1996.
    
 
   
     In October 1995 the Company's wholly-owned subsidiary, Administaff of
Texas, Inc. (Administaff of Texas), entered into a $10 million revolving credit
agreement (Credit Agreement) with a bank. Such Credit Agreement includes an
agreement to issue standby letters of credit in an amount not to exceed a
sublimit of $5 million. The Company is a guarantor under the Credit Agreement.
The Credit Agreement requires the Company to maintain certain specified
financial ratios and contains other restrictions customary in lending
transactions of this type, including a limitation on the declaration and payment
of dividends. As of September 30, 1996 the Company has no borrowings outstanding
under the agreement and has $10 million available for borrowings under the
agreement.
    
 
3. INCOME TAXES
 
     Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities used for financial
reporting purposes and the amounts used for income tax purposes. The items
resulting in deferred tax assets and liabilities include accrued workers'
compensation claims, depreciation and amortization, state income taxes, client
list acquisition costs, allowance for uncollectible accounts receivable, net
operating loss carryforwards and other accrued liabilities.
 
     In January and May 1996, the Internal Revenue Service approved the
Company's request for a change in the method of accounting for PEO service fees
and worksite employee payroll costs to the accrual method for income tax
purposes. These changes were adopted for financial reporting purposes effective
January 1, 1994. For PEO service fees the change was approved effective January
1, 1995 with a three year phase in period for the cumulative effect of the
change. For worksite employee payroll costs, the change was approved effective
January 1, 1995 with a one year phase in period for the cumulative effect of the
change. As a result, the Company amended its 1995 consolidated federal income
tax return to account for these changes. The Company received refunds totaling
$3.5 million in May and July 1996 resulting from the original and amended
federal income tax returns. Deferred income taxes at September 30, 1996 includes
the effect of the three year

phase in for the cumulative effect of the change in accounting for PEO service
fees as a component of net current and noncurrent deferred income taxes.
 
     The Company's provision for income taxes, which includes the effects of the
non-recurring charge for 401(k) Plan issues, differs from the U.S. statutory
rate of 34% due primarily to certain portions of such non-recurring charge being
non-deductible for income tax purposes. In addition, the Company's provision for
income taxes differs from the U.S. statutory rate due to state income taxes.
 
4. COMMITMENTS AND CONTINGENCIES
 
     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 adverse effect on the Company's consolidated
financial position.
 
     The Company's 401(k) plan is currently under audit by the Internal Revenue
Service (the "IRS") for the year ended December 31, 1993. Although the audit is
for the 1993 plan year, certain conclusions of the IRS would be applicable to
subsequent years as well. In addition, the IRS has established a Market Segment
Study Group on Employee Leasing for the purpose of identifying specific
compliance issues prevalent in certain segments of the PEO industry.
Approximately 70 PEOs, including the Company, have been randomly selected by the
IRS for audit pursuant to this program. One issue that has arisen from these
audits is whether a PEO can be a co-employer of worksite employees, including
officers and owners of client companies, for various purposes under the Internal
Revenue Code of 1986, as amended (the "Code"), including participation in the
PEO's 401(k) plan. With respect to the 401(k) Plan audit, the Company
understands that the IRS group conducting the audit of the Company with respect
to these issues intends to seek technical advice from the IRS National Office
about whether participation in the 401(k) Plan by officers of client companies
is permitted under the Code (the "Technical Advice Request"). The Company also
understands that, with respect to the Market Segment Study, the IRS is similarly
referring to the National Office the issue of whether a PEO and a client company
may be treated as co-employers of worksite employees for certain federal tax
purposes (the "Industry Issue").
 
     Whether the National Office will address the Technical Advice Request
independently of the Industry Issue is unclear. Should the IRS conclude that the
Company is not a "co-employer" of worksite employees for purposes of the Code,
worksite employees could not continue to make salary deferral contributions to
the 401(k) Plan or pursuant to the Company's cafeteria plan or continue to
participate in certain other employee benefit plans of the Company. The Company
believes that, although unfavorable to the Company, a prospective application of
such a conclusion (that is, one applicable only to periods after such a
conclusion is reached) would not have a material adverse effect on its financial
position or results of operations, as the Company could continue to make
available comparable benefit programs to its client companies at comparable cost
to the Company. However, if such conclusion were applied retroactively to
disqualify the 401(k) Plan for 1993 and subsequent years, employees' vested
account balances under the 401(k) Plan would become taxable, the Company would
lose its tax deductions to the extent its matching contributions were not
vested, the 401(k) Plan's trust would become a taxable trust and the Company
would be subject to liability with respect to its failure to withhold applicable
taxes with respect to certain contributions and trust earnings. Further, the
Company would be subject to liability, including penalties, with respect to its
cafeteria plan for the failure to withhold and pay taxes applicable to salary
deferral contributions by employees, including worksite employees. In such a
scenario, the Company also would face the risk of client dissatisfaction and
potential litigation. While, the Company is not able to predict either the
timing or the nature of any conclusions that may be reached as a result of the
401(k) Plan audit or the Market Segment Study, the Company believes that a
retroactive application of an unfavorable determination is unlikely. The Company

     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) -- (CONTINUED)
 
also believes that a prospective application of an unfavorable determination
will not have a material adverse effect on the Company's consolidated financial
position or results of operations.
 
     In addition to the 401(k) Plan audit and Market Segment Study, the Company
notified the IRS of certain operational issues concerning nondiscrimination test
results for certain prior plan years. In 1991 the Company engaged a third party
vendor to be the 401(k) Plan's record keeper and to perform certain required
annual nondiscrimination tests for the 401(k) Plan. Each year such record keeper
reported to the Company that such nondiscrimination tests had been satisfied.
However, in August 1996 the 401(k) Plan's record keeper advised the Company that
certain of these tests had been performed incorrectly for prior years and, in
fact, that the 401(k) Plan had failed certain tests for the 1993, 1994 and 1995
plan years. The Company has subsequently determined that the 401(k) Plan also
failed a nondiscrimination test for 1991, a closed year for tax purposes. At the
time the Company received such notice, the period in which the Company could
voluntarily "cure" an operational defect had lapsed for all such years, except
1995.
 
     With respect to the 1995 plan year, the Company is still within the time
allowable to correct the testing failure. Such correction involves refunding,
from the plan, the excess contributions and earnings thereon to the affected
employees. In connection with this correction, the Company has accrued
approximately $51,000 for an excise tax applicable to this plan year. With
respect to all other plan years, the Company has proposed a corrective action to
the IRS under which the Company would make additional contributions to certain
plan participants which bring the plan into compliance with the discrimination
tests.
 
   
     The Company has recorded an accrual for its estimate of the cost of
corrective measures and penalties for all of the affected plan years, which
accrual is reflected in Other accrued liabilities -- noncurrent on the
Consolidated Balance Sheet. The Company calculated its estimates based on its
understanding of the resolution of similar issues with the IRS. Separate
calculations were made to determine the Company's estimate of both the cost of
corrective measures and penalties for each plan year. In addition, the Company
has recorded an asset for an amount recoverable from the 401(k) Plan's record
keeper should the Company ultimately be required to pay the amount accrued for
such corrective measures and penalties, which amount is reflected in Other
assets on the Consolidated Balance Sheet. The amount of the accrual is the
Company's estimate of the cost of corrective measures and practices, although no
assurance can be given that the actual amount that the Company may be ultimately
required to pay will not substantially exceed the amount accrued. The net of
these amounts is reflected on the Company's Consolidated Statement of Operations
as a component of other income (expense), net, and their tax effect is included
in the provision for income taxes. Based on its understanding of the settlement
experience of other companies with the IRS, the Company does not believe the
ultimate resolution of this 401(k) Plan matter will have a material adverse
effect on the Company's financial condition or results of operations.
    
 
5. RELATED PARTY TRANSACTIONS
 
     In connection with an exercise of stock options in 1995, the Company
entered into a loan agreement with an officer, whereby the Company paid certain
federal income tax withholding requirements related to the stock option exercise
on behalf of the officer in the amount of $694,000. The loan agreement called
for an additional amount to be advanced to the officer in the event the ultimate
tax liability resulting from the exercise exceeded the statutory withholding
requirements. In April 1996, the Company loaned the officer an additional
$300,000 relating to this transaction. The loans are repayable in five years,
accrue interest at 6.83%, and are secured by 448,667 shares of the Company's
common stock.
 
     In April 1996, the Company entered into a settlement agreement relating to
litigation in which the Company and Technology and Business Consultants, Inc.
("TBC") were co-defendants. TBC is a company whose stockholders are three
directors/officers of the Company. In accordance with the settlement agreement,
$285,000 was paid to the plaintiff. The Company paid the entire amount of the
settlement; however, TBC has agreed to reimburse the Company for the entire
amount of the settlement not recovered through the

Company's general liability insurance. In August 1996, the Company received
$113,000 pursuant to such coverage. The remaining $172,000 is expected to be
reimbursed by TBC prior to the end of 1996.
 
     In October 1996 the Company purchased various computer equipment from TBC
at a total cost of $209,000.
 
   
6. INITIAL PUBLIC OFFERING
    
 
   
     The Company remains in registration with the Securities and Exchange
Commission for the offering of up to 3,450,000 shares of its common stock. The
timetable of the proposed offering is uncertain; however, the Company filed an
amendment to its registration statement in October 1996, responding to comments
from its initial filing and updating all information to September 30, 1996. The
Company has incurred costs totaling $1.1 million through September 30, 1996
related to the offering which are included in prepaid expenses on the
consolidated balance sheet. Upon consummation of the offering, such costs will
be reflected as a reduction to stockholders' equity.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Subsection (a) of section 145 of the General Corporation Law of the State
of Delaware empowers a corporation to indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful.
 
     Subsection (b) of Section 145 empowers a corporation to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that such
person acted in any of the capacities set forth above, against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation, except that no indemnification may be made in
respect of any claim, issue or matter as to which such person shall have been
made to be liable to the corporation unless and only to the extent that the
Court of Chancery or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of Chancery or such
other court shall deem proper.
 
     Section 145 further provides that to the extent a director or officer of a
corporation has been successful on the merits or otherwise in the defense of any
action, suit or proceeding referred to in subsections (a) and (b) of Section 145
in the defense of any claim, issue or matter therein, he shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection therewith; that indemnification provided for by Section 145
shall not be deemed exclusive of any other rights to which the indemnified party
may be entitled; that indemnification provided for by Section 145 shall, unless
otherwise provided when authorized or ratified, continue as to a person who has
ceased to be a director, officer, employee or agent and shall inure to the
benefit of such person's heirs, executors and administrators; and empowers the

corporation to purchase and maintain insurance on behalf of a director or
officer of the corporation against any liability asserted against him and
incurred by him in any such capacity, or arising out of his status as such
whether or not the corporation would have the power to indemnify him against
such liabilities under Section 145.
 
     Section 102(b)(7) of the General Corporation Law of the State of Delaware
provides that a certificate of incorporation may contain a provision eliminating
or limiting the personal liability of a director to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director
provided that such provision shall not eliminate or limit the liability of a
director (i) for any breach of the director's duty of loyalty to the corporation
or its stockholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware General Corporation Law, or (iv) for any transaction
from which the director derived an improper personal benefit.
 
     Article Eleventh of the Company's Certificate of Incorporation states that:
 
     No director of the Corporation shall be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty by such director as a director; provided, however, that this Article
Eleventh shall not eliminate or limit the liability of a director to the extent
provided by applicable law (i) for any breach of the director's duty of loyalty
to the Corporation or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) under Section 174 of the General Corporation Law of the State of Delaware
or (iv) for any transaction from which the director derived an improper personal
benefit. No amendment to or repeal of this Article Eleventh shall apply to, or
have any effect on, the liability or alleged liability of any director of the
Corporation for or with respect to any facts or omissions of such director
occurring prior to such amendment or repeal. If the General Corporation Law of
the State of Delaware is amended to authorize corporate action further
eliminating or limiting the personal liability of directors, then the liability
of a director of the Corporation shall be eliminated or limited to the fullest
extent permitted by the General Corporation Law of the State of Delaware, as so
amended.
 
     In addition, Article VI of the Company's Bylaws further provides that the
Company shall indemnify its officers, directors and employees to the fullest
extent permitted by law.
 
     Pursuant to the Underwriting Agreement filed as Exhibit 1.1 to this
Registration Statement, the Underwriters have agreed to indemnify, under certain
conditions, the Company, its officers and directors, and persons who control the
Company within the meaning of the Securities Act of 1933, as amended, against
certain liabilities.

     Pursuant to Item 601(b)(4)(iii) of Regulation S-K, the Company has not
filed any instrument with respect to long-term debt not being registered if the
total amount of securities authorized thereunder does not exceed 10 percent of
the total assets of the Company and agrees to file a copy of such instruments
with the Commission upon request.
 
ITEM 17. UNDERTAKINGS
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act, and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
     The undersigned registrant hereby undertakes:
 
          (1) That for purposes of determining any liability under the
     Securities Act of 1933, 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) That for the purpose of determining any liability under the
     Securities Act of 1933, each posteffective amendment that contains a form
     of prospectus 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.
 
          (3) To provide to the underwriters at the closing specified in the
     underwriting agreement certificates in such denominations and registered in
     such names as required by the underwriters to permit prompt delivery to
     each purchaser.

thereto shall be calculated based on a 365-day year.

       The Company shall pay accrued interest on the outstanding principal
balance hereof on the last day of March, June, September and December of each

from the due date thereof until paid.

       This Subordinated Note is issued pursuant to a Securities Purchase

"Agreement"), and the holder hereof is entitled to the benefits thereof and
subject to the restrictions on transfer contained therein.  In addition, the
holder hereof may be entitled to certain rights pursuant to the Voting

       The sale or other transfer of this Subordinated Note is restricted by
the Company's right of first refusal as described in the Agreement.

       The payment of this Subordinated Note is subordinated to the prior

       Upon the satisfaction of the conditions set forth in the Agreement and
subject to the other terms and conditions of the Agreement, the Company may
prepay this Subordinated Note in whole or in part, plus accrued interest
thereon, as provided in the Agreement.  The Company agrees to make any
prepayments of principal that may be required pursuant to the terms of the
Agreement on the dates and in the amounts specified in the Agreement.

       In addition, this Subordinated Note is subject to mandatory prepayment
of the full principal amount then owing, plus accrued interest, upon the
occurrence of certain events set forth in the Agreement.

       In case an Event of Default (as defined in the Agreement) shall occur
and be continuing, the principal of this Subordinated Note may be declared or
otherwise become due and payable in the manner and with the effect provided in
the Agreement.

       The Company hereby waives presentment and demand for payment, notice of
intent to accelerate maturity, notice of acceleration of maturity, protest or
notice of protest and nonpayment, bringing of suit and diligence in taking any
action to collect any sums owing hereunder and in proceeding against any of the
rights and properties securing payment hereof, and agrees that its liability on
this Subordinated Note shall not be affected by any release of or change in any
security for the payment of this Subordinated Note.

       It is expressly stipulated and agreed to be the intent of the Company
and the registered holder hereof to at all times comply with the usury and
other laws applicable to this Subordinated Note and any instruments securing
the payment hereof (the "Security Instruments") and any subsequent revisions,
repeals, or judicial interpretations thereof, to the extent any of the same are
applicable hereto.  If any amount called for under this Subordinated Note or
under any of the Security Instruments, or contracted for, charged, or received
with respect to the indebtedness evidenced by this Subordinated Note, or if the
exercise of the option herein contained to accelerate the maturity of this
Subordinated Note or any prepayment by the Company results in the Company
having paid any interest in excess of that permitted by law, then it is the
express intent of the Company and the registered holder hereof that all excess
amounts theretofore collected by the registered holder hereof be credited on
the principal balance of this Subordinated Note (or, if this Subordinated Note
has been paid in full, refunded to the Company), and the provisions of this
Subordinated Note and the Security Instruments immediately be deemed reformed
and the amounts thereafter collectable hereunder and thereunder reduced,
without the necessity of the execution of any new document, so as to comply
with the then applicable law, but so as to permit the recovery of the fullest
amount otherwise called for hereunder and thereunder.

Gentlemen:

              We have acted as counsel for Administaff, Inc., a Delaware
corporation (the "Company"), in connection with the Company's Registration
Statement on Form S-1 (the "Registration Statement") relating to the
registration under the Securities Act of 1933, as amended, of the offering and
sale of up to an aggregate of 3,450,000 shares (the "Shares") of common stock
of the Company, $.01 par value per share (the "Common Stock").  The Shares
include 3,000,000 shares being offered by the Company and 450,000 shares of
Common Stock which may be sold pursuant to an over-allotment option granted to
the Underwriters named in the Registration Statement by the selling
stockholders (the "Selling Stockholders") identified in the Registration
Statement.

              As the basis for the opinion hereinafter expressed, we have
examined such statutes, regulations, corporate records and documents,
certificates of corporate and public officials, and other instruments as we
have deemed necessary or advisable for the purposes of this opinion.  In such
examination we have assumed the authenticity of all documents submitted to us
as originals and the conformity with the original documents of all documents
submitted to us as copies.

              Based on the foregoing and on such legal considerations as we
deem relevant, we are of the opinion that:

              1.     The Shares to be issued by the Company will, when issued
and paid for as described in the Registration Statement, be validly issued,
fully paid and non-assessable.

For purposes of this Agreement, the Borrower's Status will be determined based
on the following definitions:

         "Level I Status" exists at any date if, as of the last day of the
fiscal quarter of the Borrower referred to in the Financials, the Leverage
Ratio is less than or equal to 0.50 to 1.0.

         "Level II Status" exists at any date if, as of the last day of the
fiscal quarter of the Borrower referred to in the Financials, (i) the
requirements necessary to achieve Level I Status shall not have been satisfied
and (ii) the Leverage Ratio is less than or equal to 1.20 to 1.0.

         "Level III Status" exists at any date if, as of the last day of the
fiscal quarter of the Borrower referred to in the Financials, (i) the
requirements necessary to achieve either Level I Status or Level II Status
shall not have been satisfied and (ii) the Leverage Ratio is less than or equal
to 2.60 to 1.0.

         "Level IV Status" exists at any date if the requirements necessary to
achieve Level I Status, Level II or Level III Status shall not have been
satisfied.

          2.5.   Fees.  In addition to the Facility Letter of Credit Fees and
issuance fees identified in Section 3.8, the Borrower agrees to pay the
following fees:

                 2.5.1    Commitment Fee.  The Borrower agrees to pay to the
         Agent for the account of each Lender a commitment fee, at a rate per
         annum equal to the rate indicated as the Applicable Margin for the
         commitment fee, on the daily unused portion of such Lender's
         Commitment from the date hereof to and including the Termination Date,
         payable on each Payment Date hereafter and on the Termination Date.
         For purposes of calculating utilization, the Aggregate Commitment
         shall be deemed used to the extent of the principal amount of the
         Advances then outstanding plus the amount of the Facility Letter of
         Credit Obligations.

                 2.5.2.   Agent's Fee.  The Borrower agrees to pay to the
         Agent, for its own account, the fees agreed to by the Borrower and the
         Agent pursuant to that certain letter agreement dated June 6, 1995, as
         amended from time to time in a writing executed by the Borrower and
         the Agent.

         2.6.    Reductions in Aggregate Commitment.  The Borrower may
permanently reduce the Aggregate Commitment in whole, or in part ratably among
the Lenders in integral multiples of $250,000, upon at least ten Business Days'
written notice to the Agent, which notice shall specify the amount of any such
reduction, provided, however, that the amount of the Aggregate Commitment may
not be reduced below the aggregate principal amount of the outstanding
Advances.  All accrued commitment fees shall be payable on the effective date
of any termination of the obligations of the Lenders to make Loans hereunder.

           2.7.  Principal Payments.

                 2.7.1.   Optional Principal Payments.  The Borrower may from
         time to time pay, without penalty or premium, all outstanding
         Alternate Base Rate Advances, or, in a minimum aggregate amount of
         $50,000, any portion of the outstanding Alternate Base Rate Advances,
         in each case 




                                      12
<PAGE>   19

         upon at least two Business Days' prior notice to the Agent.  A
         Eurodollar Advance may not be paid prior to the last day of the
         applicable Interest Period.
        
                 2.7.2.   Payment on Termination Date.  Any outstanding
         Advances and all other unpaid Obligations shall be paid in full by the
         Borrower on the Termination Date.

         2.8.  Method of Selecting Types and Interest Periods for New Advances. 
The Borrower shall select the Type of Advance and, in the case of each
Eurodollar Advance, the Interest Period applicable to each Advance from time to
time.  The Borrower shall give the Agent irrevocable notice (a "Borrowing
Notice") not later than 10:00 a.m. (Chicago time) on the Borrowing Date of each
Alternate Base Rate Advance, and at least three Business Days before the
Borrowing Date for each Eurodollar Advance, specifying:

      (i)   the Borrowing Date, which shall be a Business Day, of such
            Advance,
           
     (ii)   the aggregate amount of such Advance,
           
    (iii)   the Type of Advance selected, and
           
     (iv)   in the case of each Eurodollar Advance, the Interest Period
            applicable thereto.

Not later than noon (Chicago time) on each Borrowing Date, each Lender shall
make available its Loan or Loans, in funds immediately available in Chicago to
the Agent at its address specified pursuant to Article XIV.  The Agent will
make the funds so received from the Lenders available to the Borrower at the
Agent's aforesaid address.

          2.9.   Conversion and Continuation of Outstanding Advances.
Alternate Base Rate Advances shall continue as Alternate Base Rate Advances
unless and until such Alternate Base Rate Advances are converted into
Eurodollar Advances.  Each Eurodollar Advance shall continue as a Eurodollar
Advance until the end of the then applicable Interest Period therefor, at which
time such Eurodollar Advance shall be automatically converted into an Alternate
Base Rate Advance unless the Borrower shall have given the Agent a
Conversion/Continuation Notice requesting that, at the end of such Interest
Period, such Eurodollar Advance continue as a Eurodollar Advance for the same
or another Interest Period.  Subject to the terms of Section 2.3, the Borrower
may elect from time to time to convert all or any part of an Alternate Base
Rate Advance into a Eurodollar Advance.  The Borrower shall give the Agent
irrevocable notice (a "Conversion/Continuation Notice") of each conversion of
an Alternate Base Rate Advance or continuation of a Eurodollar Advance not
later than 10:00 a.m. (Chicago time) at least three Business Days prior to the
date of the requested conversion or continuation, specifying:

      (i)   the requested date which shall be a Business Day, of such
            conversion or continuation;
            
     (ii)   the aggregate amount and Type of the Advance which is to be
            converted or continued; and
            
    (iii)   the amount and Type(s) of Advance(s) into which such Advance
            is to be converted or continued and, in the case of a
            conversion into or continuation of a Eurodollar Advance, the
            duration of the Interest Period applicable thereto.




                                      13
<PAGE>   20

         2.10.   Changes in Interest Rate, etc.  Each Alternate Base Rate
Advance shall bear interest on the outstanding principal amount thereof, for
each day from and including the date such Advance is made or is converted from
a Eurodollar Advance into an Alternate Base Rate Advance pursuant to Section
2.9 to but excluding the date it becomes due or is converted into a Eurodollar
Advance pursuant to Section 2.9 hereof, at a rate per annum equal to the
Alternate Base Rate for such day.  Changes in the rate of interest on that
portion of any Advance maintained as an Alternate Base Rate Advance will take
effect simultaneously with each change in the Alternate Base Rate.  Each
Eurodollar Advance shall bear interest from and including the first day of the
Interest Period applicable thereto to (but not including) the last day
of such Interest Period at the interest rate determined as applicable to such
Eurodollar Advance.  No Interest Period may end after the Termination Date.

         2.11.   Rates Applicable After Default.  Notwithstanding anything to
the contrary contained in Section 2.8 or 2.9, during the continuance of a
Default or Unmatured Default the Required Lenders may, at their option, by
notice to the Borrower, declare that no Advance may be made as, converted into
or continued as a Eurodollar Advance.  During the continuance of a Default the
Required Lenders may, at their option, by notice to the Borrower, declare that
(i) each Eurodollar Advance shall bear interest for the remainder of the
applicable Interest Period at the rate otherwise applicable to such Interest
Period plus 2% per annum and (ii) each Alternate Base Rate Advance shall bear
interest at a rate per annum equal to the Alternate Base Rate plus 2% per
annum.

         2.12.   Method of Payment.  All payments of the Obligations hereunder
shall be made, without setoff, deduction, or counterclaim, in immediately
available funds to the Agent at the Agent's address specified pursuant to
Article XIV, or at any other Lending Installation of the Agent specified in
writing by the Agent to the Borrower, by noon (local time) on the date when due
and shall be applied ratably by the Agent among the Lenders.  Each payment
delivered to the Agent for the account of any Lender shall be delivered
promptly by the Agent to such Lender in the same type of funds that the Agent
received at its address specified pursuant to Article XIV or at any Lending
Installation specified in a notice received by the Agent from such Lender.  The
Agent is hereby authorized, upon notice to the Borrower, to charge the account
of the Borrower maintained with First Chicago for each payment of principal,
interest and fees as it becomes due hereunder.

         2.13.   Notes; Telephonic Notices.  Each Lender is hereby authorized
to record the principal amount of each of its Loans and each repayment on the
schedule attached to its Note, provided, however, that the failure to so record
shall not affect the Borrower's obligations under such Note.  The Borrower
hereby authorizes the Lenders and the Agent to extend, convert or continue
Advances, effect selections of Types of Advances and to transfer funds based on
telephonic notices made by any person or persons the Agent or any Lender in
good faith and in the exercise of its reasonable judgment believes to be acting
on behalf of the Borrower.  The Borrower agrees to deliver promptly to the
Agent a written confirmation signed by an Authorized Officer, if such
confirmation is requested by the Agent or any Lender, of each telephonic
notice.  If the written confirmation differs in any material respect from the
action taken by the Agent and the Lenders in accordance with any such
telephonic notice, the records of the Agent and the Lenders shall govern absent
manifest error.

         2.14.   Interest Payment Dates; Interest and Fee Basis.  Interest
accrued on each Alternate Base Rate Advance shall be payable on each Payment
Date, commencing with the first such date to occur after the date hereof and at
maturity.  Interest accrued on each Eurodollar Advance shall be payable on the
last day of its applicable Interest Period, on any date on which the Eurodollar
Advance is prepaid, whether by 




                                      14
<PAGE>   21


acceleration or otherwise, and at maturity. Interest on Eurodollar Advances and
commitment fees shall be calculated for actual days elapsed on the basis of a
360-day year; interest on Alternate Base Rate Advances shall be calculated for
actual days elapsed on the basis of a 365, or when applicable 366, day year. 
Interest shall be payable for the day an Advance is made but not for the day of
any payment on the amount paid if payment is received prior to 1:00 p.m. (local
time) at the place of payment. If any payment of principal of or interest on an
Advance shall become due on a day which is not a Business Day, such payment
shall be made on the next succeeding Business Day and, in the case of a
principal payment, such extension of time shall be included in computing
interest in connection with such payment.
        
         2.15.   Notification by Agent.  Promptly after receipt thereof, the
Agent will notify each Lender of the contents of each Aggregate Commitment
reduction notice, Borrowing Notice, Conversion/Continuation Notice, Letter of
Credit Request, Issuance Notice and repayment notice (required pursuant to
Section 2.7.1) received by it hereunder.  The Agent will notify each Lender of
the interest rate applicable to each Eurodollar Advance promptly upon
determination of such interest rate and will give each Lender prompt notice of
each change in the Alternate Base Rate.

         2.16.   Lending Installations.  Each Lender may book its Loans at any
Lending Installation selected by such Lender and may change its Lending
Installation from time to time.  All terms of this Agreement shall apply to any
such Lending Installation and the Notes shall be deemed held by each Lender for
the benefit of such Lending Installation.  Each Lender may, by written or telex
notice to the Agent and the Borrower, designate a Lending Installation through
which Loans will be made by it and for whose account Loan payments are to be
made.

         2.17.   Non-Receipt of Funds by the Agent.  Unless the Borrower or a
Lender, as the case may be, notifies the Agent prior to the date on which it is
scheduled to make payment to the Agent of (i) in the case of a Lender, the
proceeds of a Loan or its share of the unreimbursed amount pursuant to Section
3.6(b) or (ii) in the case of the Borrower, a payment of principal, interest or
fees to the Agent for the account of the Lenders, that it does not intend to
make such payment, the Agent may assume that such payment has been made.  The
Agent may, but shall not be obligated to, make the amount of such payment
available to the intended recipient in reliance upon such assumption.  If such
Lender or the Borrower, as the case may be, has not in fact made such payment
to the Agent, the recipient of such payment shall, on demand by the Agent,
repay to the Agent the amount so made available together with interest thereon
in respect of each day during the period commencing on the date such amount was
so made available by the Agent until the date the Agent recovers such amount at
a rate per annum equal to (i) in the case of payment by a Lender, the Federal
Funds Effective Rate for such day or (ii) in the case of payment by the
Borrower, the interest rate applicable to the relevant Loan.

         2.18.   Withholding Tax Exemption. Upon the execution hereof (or upon
the execution of any Assignment Agreement for any Lender not an original
signatory to this Agreement), each Lender that is not organized under the laws
of the United States of America, or a state thereof, or which books its Loans
at a Lending Installation which is not organized under the United States of
America, or a state thereof, agrees that it will deliver to each of the
Borrower and the Agent two duly completed copies of United States Internal
Revenue Service Form 1001 or 4224, certifying in either case that such Lender
is entitled to receive payments under this Agreement and the Notes without
deduction or withholding of any United States federal income taxes.  Each
Lender which so delivers a Form 1001 or 4224 further undertakes to deliver to
each of the Borrower and the Agent two additional copies of such form (or a
successor form) on or before the date that such form expires (currently, three
successive calendar years for Form 1001 and 




                                      15
<PAGE>   22

one calendar year for Form 4224) or becomes obsolete or after the occurrence of
any event requiring a change in the most recent forms so delivered by it, and
such amendments thereto or extensions or renewals thereof as may be reasonably
requested by the Borrower or the Agent, in each case certifying that such Lender
is entitled to receive payments under this Agreement and the Notes without
deduction or withholding of any United States federal income taxes, unless an
event (including without limitation any change in treaty, law or regulation) has
occurred prior to the date on which any such delivery would otherwise be
required which renders all such forms inapplicable or which would prevent such
Lender from duly completing and delivering any such form with respect to it and
such Lender advises the Borrower and the Agent that it is not capable of
receiving payments without any deduction or withholding of United States federal
income tax.  If any Lender is required under this Section 2.18 to provide a form
described above and fails to deliver such form to the Borrower and the Agent
(other than as a result of any change in treaty, law or regulation which renders
all such forms inapplicable or which prevents such Lender from duly completing
and delivering any such form with respect to it), then to the extent required by
law, the Borrower shall be entitled to deduct or withhold taxes from the
payments owed to such Lender and the Borrower shall not be obligated to make any
payment to such Lender under Section 4.1 or otherwise with respect to the amount
so deducted or withheld.
        
         2.19.   Extension of Termination Date.  The Borrower may request up to
two one year extensions of the Termination Date by submitting a request for an
extension to the Agent (an "Extension Request") no more than 60 days prior to
any anniversary of the date of this Agreement.  The Extension Request must
specify the date (which must be at least 30 days after the Extension Request is
delivered to the Agent) as of which the Lenders must respond to the Extension
Request (the "Extension Date").  Promptly upon receipt of an Extension Request,
the Agent shall notify each Lender of the contents thereof and shall request
each Lender to approve the Extension Request.  Each Lender approving the
Extension Request shall deliver its written consent no later than the Extension
Date.  Any consent delivered by a Lender to the Agent prior to the Extension
Date may be revoked prior to the Extension Date by the Lender giving written
notice of such revocation to the Agent before the Extension Date.  If the
consent of each of the Lenders is received by the Agent and remains in effect
on the Extension Date, the Termination Date shall automatically be deemed to
have been extended by one year and the Agent shall promptly notify the Borrower
and each Lender of the new Termination Date.

                                  ARTICLE III

of the following conditions:

                 (a)      the Borrower shall have delivered to the Issuing Bank
at such times and in such manner as the Issuing Bank may reasonably prescribe
such documents and materials as may be required pursuant to the terms of the

                 (b)      as of the date of issuance, no order, judgment or
decree of any court, arbitrator or governmental authority shall purport by its
terms to enjoin or restrain the Issuing Bank from issuing the requested

Issuing Bank and no request or directive (whether or not having the force of
law) from any governmental authority with jurisdiction over the Issuing Bank
shall prohibit or request that the Issuing Bank refrain from the issuance of
Letters of Credit generally or the issuance of the requested Facility Letter or
Credit in particular; and

                 (c)      the Issuing Bank and the Borrower having agreed on
the issuance fee referred to in Section 3.8(b).

         3.4.    Procedure for Issuance of Facility Letters of Credit.

                 (a)      The Borrower shall give the Issuing Bank and the
Agent prior written notice of any requested issuance of a Facility Letter of
Credit under this Agreement (a "Letter of Credit Request"), which written
notice must be received no later than 10:00 a.m. (Chicago time) on a day which
is at least two (2) Business Days prior to the date of issuance thereof (except
that, in lieu of such written notice, the Borrower may give the Issuing Bank
and the Agent telephonic notice of such request if confirmed in writing by
delivering to the Issuing Bank and the Agent (i) immediately (A) a facsimile of
the written notice required hereunder which has been signed by an Authorized
Officer or (B) a telex containing all information required to be contained in
such written notice and (ii) promptly thereafter (but in no event later than 
the 




                                      17
<PAGE>   24

requested date of issuance), the written notice required hereunder containing
the original signature of an Authorized Officer).  Each Letter of Credit Request
shall be irrevocable and shall specify:
        
         (1)     the stated amount of the Facility Letter of Credit requested
                 (which stated amount shall not be less than $100,000);

         (2)     the effective date (which day shall be a Business Day) of
                 issuance of such requested Facility Letter of Credit (the
                 "Issuance Date");

         (3)     the date on which such requested Facility Letter of Credit is
                 to expire (which date shall be a Business Day and shall in no
                 event be later than the earlier of the Termination Date and a
                 date which is twelve (12) months after the Issuance Date);

         (4)     the purpose for which such Facility Letter of Credit is to be
                 issued; and

         (5)     the Person for whose benefit the requested Facility Letter of
                 Credit is to be issued.

At the time any such Letter of Credit Request is made, the Borrower shall also
provide the Agent and the Issuing Bank with a copy of the form of the Facility
Letter of Credit it is requesting be issued.

                 (b)      Subject to the terms and conditions of this Article
III and provided that the applicable conditions set forth in Section 5.2 hereof
have been satisfied, the Issuing Bank shall, on the Issuance Date, issue a
Facility Letter of Credit on behalf of the Borrower in accordance with the
Issuing Bank's usual and customary business practices unless the Issuing Bank
has actually received (i) written notice from the Borrower specifically
revoking the Letter of Credit Request with respect to such Facility Letter of
Credit, (ii) written notice from a Lender, which complies with the provisions
of Section 3.6(a) or (iii) written or telephonic notice from the Agent stating
that the issuance of such Facility Letter of Credit would violate Section 3.2.

                 (c)      The Issuing Bank shall give the Agent and the
Borrower written or telex notice, or telephonic notice confirmed promptly
thereafter in writing, of the issuance of a Facility Letter of Credit (the
"Issuance Notice").

                 (d)      The Issuing Bank shall not extend or amend any
Facility Letter of Credit or allow any Facility Letter of Credit to be
automatically extended unless the requirements of this Agreement are met as
though a new Facility Letter of Credit was being requested and issued.

         3.5.    Reimbursement Obligations; Duties of Issuing Banks.

                 (a) (i)  The Issuing Bank shall promptly notify the
Borrower and the Agent of any draw under a Facility Letter of Credit and the
Borrower shall reimburse the Issuing Bank in accordance with Section 3.7; and
(ii) any Reimbursement Obligation with respect to any Facility Letter of Credit
shall bear interest from the date of the relevant drawings under the pertinent
Facility Letter of Credit until payment in full is received by the Issuing Bank
at (A) the Alternate Base Rate until the next succeeding Business Day and (B)
the Default interest rate for Alternate Base Rate Advances calculated in
accordance with Section 2.11 for each day thereafter.





                                   18
<PAGE>   25

                 (b)      Any action taken or omitted to be taken by the
Issuing Bank under or in connection with any Facility Letter of Credit, if
taken or omitted in the absence of willful misconduct or gross negligence,
shall not put the Issuing Bank under any resulting liability to any Lender or,
assuming that the Issuing Bank has complied with the procedures specified in
Section 3.4, all conditions to the issuance of a Facility Letter of Credit have
been satisfied and such Lender has not given a notice contemplated by Section
3.6(a) that continues in full force and effect, relieve that Lender of its
obligations hereunder to the Issuing Bank.  In determining whether to pay under
any Facility Letter of Credit, the Issuing Bank shall have no obligation
relative to the Lenders other than to confirm that any documents required to be
delivered under such Letter of Credit appear to have been delivered in
compliance and that they appear to comply on their face, with the requirements
of such Letter of Credit.

         3.6.    Participation.

                 (a)      Immediately upon issuance by the Issuing Bank of any
Facility Letter of Credit in accordance with the procedures set forth in
Section 3.4, each Lender shall be deemed to have irrevocably and
unconditionally purchased and received from the Issuing Bank, without recourse,
representation or warranty, an undivided interest and participation equal to
its Percentage in such Facility Letter of Credit (including, without
limitation, all obligations of the Borrower with respect thereto) and any
security therefor or guaranty pertaining thereto; provided, that a Letter of
Credit issued by the Issuing Bank shall not be deemed to be a Facility Letter
of Credit for purposes of this Section 3.6 if the Issuing Bank shall have
received written notice from any Lender on or before the Business Day prior to
the date of its issuance of such Letter of Credit that one or more of the
conditions to the issuance of a Facility Letter of Credit is not then
satisfied, and, in the event the Issuing Bank receives such a notice, it shall
have no further obligation to issue any Facility Letter of Credit until such
notice is withdrawn by that Lender or it receives a notice from the Agent that
such condition has been effectively waived in accordance with the provisions of
this Agreement.

                 (b)      In the event that the Issuing Bank makes any payment
under any Facility Letter of Credit and the Borrower shall not have repaid such
amount to the Issuing Bank pursuant to Section 3.7 hereof, the Issuing Bank
shall promptly notify the Agent, which shall promptly notify each Lender, of
such failure, and each Lender shall promptly and unconditionally pay to the
Agent for the account of the Issuing Bank the amount of such Lender's
Percentage of the unreimbursed amount of such payment, and the Agent shall
promptly pay such amount to the Issuing Bank.  The failure of any Lender to
make available to the Agent for the account of the Issuing Bank its Percentage
of the unreimbursed amount of any such payment shall not relieve any other
Lender of its obligation hereunder to make available to the Agent for the
account of the Issuing Bank its Percentage of the unreimbursed amount of any
payment on the date such payment is to be made, but no Lender shall be
responsible for the failure of any other Lender to make available to the Agent
its Percentage of the unreimbursed amount of any payment on the date such
payment is to be made.

                 (c)      Whenever the Issuing Bank receives a payment on
account of a Reimbursement Obligation, including any interest thereon, it shall
promptly pay to the Agent and the Agent shall promptly pay to each Lender which
has funded its participating interest therein, in immediately available funds,
an amount equal to such Lender's Percentage thereof.

                 (d)      Upon the request of the Agent or any Lender, the
Issuing Bank shall furnish to the Agent or Lender copies of any Facility Letter
of Credit to which that Issuing Bank is party and such other documentation as
may reasonably be requested by the Agent or Lender.

                 (e)      The obligations of a Lender to make payments to the
Agent for the account of the Issuing Bank with respect to a Facility Letter of
Credit shall be absolute, unconditional and irrevocable, not subject to any
counterclaim, set-off, qualification or exception whatsoever and shall be made
in accordance with the terms and conditions of this Agreement under all
circumstances.

         3.7.    Payment of Reimbursement Obligations.

                 (a)  The Borrower agrees to pay to the Issuing Bank the amount
of all Reimbursement Obligations, interest and other amounts payable to the
Issuing Bank under or in connection with any Facility Letter of Credit
immediately when due (and in any event  shall reimburse the Issuing Bank for
drawings under a Facility Letter of Credit issued by it no later than the next
succeeding Business Day after the payment by that Issuing Bank), irrespective
of any claim, set-off, defense or other right which the Borrower or any
Subsidiary may have at any time against the Issuing Bank or any other Person,
under all circumstances, including without limitation any of the following
circumstances:

                 (i)      any lack of validity or enforceability of this
                          Agreement or any of the other Loan Documents;

                 (ii)     the existence of any claim, setoff, defense or other
                          right which the Borrower may have at any time against
                          a beneficiary named in a Facility Letter of Credit or
                          any transferee of any Facility Letter of Credit (or
                          any Person for whom any such transferee may be
                          acting), the Agent, the Issuing Bank, any Lender, or
                          any other Person, whether in connection with this
                          Agreement, any Facility Letter of Credit, the
                          transactions contemplated herein or any unrelated
                          transactions (including any underlying transactions
                          between the Borrower or any Subsidiary and the
                          beneficiary named in any Facility Letter of Credit);

                 (iii)    any draft, certificate or any other document
                          presented under the Facility Letter of Credit proving
                          to be forged, fraudulent, invalid or insufficient in
                          any respect or any statement therein being untrue or
                          inaccurate in any respect;

                 (iv)     the surrender or impairment of any security for the
                          performance or observance of any of the terms of any
                          of the Loan Documents; or

                 (v)      the occurrence of any Default or Unmatured Default.

                 (b)      In the event any payment by the Borrower or any
Subsidiary received by the Issuing Bank with respect to a Facility Letter of
Credit and distributed by the Agent to the Lenders on account of their
participations is thereafter set aside, avoided or recovered from the Issuing
Bank in connection with any receivership, liquidation, reorganization or
bankruptcy proceeding, each Lender which received such distribution shall, upon
demand by the Issuing Bank, contribute such Lender's Percentage of the amount
set aside, avoided or recovered together with interest at the rate required to
be paid by the Issuing Bank upon the amount required to be repaid by it.

         3.8.    Compensation for Facility Letters of Credit.

                 (a)      The Borrower shall pay to the Agent, for the ratable
account of the Lenders, based upon the Lenders' respective Percentages, a fee
(the "Facility Letter of Credit Fee") with respect to each Facility Letter of
Credit, in an amount equal to the product of the average daily undrawn amount
of such Facility Letter of Credit times the percentage indicated as the
Applicable Margin for the Facility Letter of Credit Fee, for the period from
the Issuance Date thereof to but including the final expiration date thereof.
The Facility Letter of Credit Fee shall be due and payable in arrears on each
Payment Date and, to the extent any such fees are then due and unpaid, on the
Termination Date.  The Agent shall promptly remit such Facility Letter of
Credit Fees, when paid, to the other Lenders in accordance with their
Percentages thereof.

                 (b)      The Issuing Bank shall have the right to receive
solely for its own account such amounts as it and the Borrower may agree, in
writing, to pay to the Issuing Bank with respect to issuance
fees for any Facility Letter of Credit.  In addition, the Issuing Bank shall be
entitled to receive its reasonable out-of-pocket costs of issuing and servicing
Facility Letters of Credit.

          3.9.   Letter of Credit Collateral Account.  The Borrower hereby
agrees that at the request of the Agent following an acceleration of the
Obligations pursuant to Section 9.1 it will, until the  Termination Date,
maintain a special collateral account (the "Letter of Credit Collateral
Account") at the Agent's office at the address specified pursuant to Article
XIV, in the name of the Borrower but under the sole dominion and control of the
Agent, for the benefit of the Lenders, and in which the Borrower shall have no
interest other than as set forth in Section 9.1.  In addition to the foregoing,
the Borrower hereby grants to the Agent, for the benefit of the Lenders, a
security interest in and to the Letter of Credit Collateral Account and any
funds that may hereafter be on deposit in such account.

                                   ARTICLE IV

                            CHANGE IN CIRCUMSTANCES

          4.1.   Yield Protection.  If, on or after the date hereof, the
adoption of any applicable law, rule, regulation, policy, or directive, or any
change in any applicable law, rule, regulation, policy or directive or any
change in the interpretation or administration thereof by any governmental or
quasi-governmental authority charged with the interpretation or administration
thereof (whether or not having the force of law) or compliance by any Lender
therewith,

         (i)     subjects any Lender or any applicable Lending Installation to
                 any tax, duty, charge or withholding on or from payments due
                 from the Borrower (excluding federal taxation of the overall
                 net income of any Lender or applicable Lending Installation),
                 or changes the basis of taxation of payments to any Lender in
                 respect of its Loans, its interest in the Facility Letters of
                 Credit or other amounts due it hereunder, or

         (ii)    imposes or increases or deems applicable any reserve,
                 assessment, insurance charge, special deposit or similar
                 requirement against assets of, deposits with or for the
                 account of, or credit extended by, any Lender or any
                 applicable Lending Installation (other than 




                                      21
<PAGE>   28


                 reserves and assessments taken into account in determining the
                 interest rate applicable to Eurodollar Advances), or
        
         (iii)   imposes any other condition the result of which is to increase
                 the cost to any Lender or any applicable Lending Installation
                 of making, funding, issuing, participating in or maintaining
                 the Loans or the Facility Letters of Credit or reduces any
                 amount receivable by any Lender or any applicable Lending
                 Installation in connection with the Loans or the  Facility
                 Letters of Credit, or requires any Lender or any applicable
                 Lending Installation to make any payment calculated by
                 reference to the amount of the Loans held, Facility Letters of
                 Credit issued or participated in or interest received by it,
                 by an amount deemed material by such Lender,

then, within 30 days of demand by such Lender, the Borrower shall pay such
Lender that portion of such increased expense incurred or reduction in an
amount received which such Lender determines is attributable to making, funding
and maintaining its Loans, its interest in the Facility Letters of Credit  and
its Commitment; provided, however, that notwithstanding the foregoing, the
Borrower shall only be obligated to compensate such Lender for any such amount
arising or accruing during (1) any time or period commencing not more than 90
days prior to the date on which such Lender notifies the Borrower that it
proposes to demand such compensation and identifies to the Borrower the law,
rule, regulation, policy, directive or other basis upon which the claimed
compensation is or will be based and (ii) any time or period during which,
because of the retroactive application of such law, rule, regulation, policy,
directive or other basis, such Lender did not know that such amount would arise
or accrue.

          4.2.   Changes in Capital Adequacy Regulations.  If a Lender
determines the amount of capital required or expected to be maintained by such
Lender, any Lending Installation of such Lender or any corporation controlling
such Lender is increased as a result of a Change, then, within 30 days of
demand by such Lender, the Borrower shall pay such Lender the amount necessary
to compensate for any shortfall in the rate of return on the portion of such
increased capital which such Lender determines is attributable to this
Agreement, its Loans, its interest in the Facility Letters of Credit or its
obligation to make Loans, participate in or issue Facility Letters of Credit
hereunder (after taking into account such Lender's policies as to capital
adequacy); provided, however, that notwithstanding the foregoing, the Borrower
shall only be obligated to compensate such Lender for any such amount arising
or accruing during (1) any time or period commencing not more than 90 days
prior to the date on which such Lender notifies the Borrower that it proposes
to demand such compensation and identifies to the Borrower the Change upon
which the claimed compensation is or will be based and (ii) any time or period
during which, because of the retroactive application in respect of such Change,
such Lender did not know that such amount would arise or accrue.  "Change"
means (i) any change after the date of this Agreement in the Risk-Based Capital
Guidelines or (ii) any adoption of or change in any other law, governmental or
quasi-governmental rule, regulation, policy, guideline, interpretation, or
directive (whether or not having the force of law) after the date of this
Agreement which affects the amount of capital required or expected to be
maintained by any Lender or any Lending Installation or any corporation
controlling any Lender.  "Risk-Based Capital Guidelines" means (i) the
risk-based capital guidelines in effect in the United States on the date of
this Agreement, including transition rules, and (ii) the corresponding capital
regulations promulgated by regulatory authorities outside the United States
implementing the July 1988 report of the Basle Committee on Banking Regulation
and Supervisory Practices Entitled "International Convergence of Capital
Measurements and Capital Standards," including transition rules, and any
amendments to such regulations adopted prior to the date of this Agreement.

<PAGE>   29

          4.3.   Availability of Types of Advances.  If any Lender determines
that maintenance of its Eurodollar Loans at a suitable Lending Installation
would violate any applicable law, rule, regulation, or directive, whether or
not having the force of law, or if the Required Lenders determine that (i)
deposits of a type and maturity appropriate to match fund Eurodollar Advances
are not available or (ii) the Eurodollar Rate does not accurately reflect the
cost of making or maintaining a Eurodollar Advance, then the Agent shall so
notify the Borrower and shall suspend (until such time as the circumstances
giving rise to such suspension shall no longer exist) the availability of
Eurodollar Advances and require any Eurodollar Advances to be repaid.

         4.4.   Funding Indemnification.  If any payment of a Eurodollar Advance
occurs on a date which is not the last day of the applicable Interest Period,
whether because of acceleration, prepayment or otherwise (but excluding any
prepayment required to be made pursuant to Section 4.3(ii)), or a Eurodollar
Advance is not made on the date specified by the Borrower for any reason other
than default by the Lenders, the Borrower will indemnify each Lender for any
loss or cost incurred by it resulting therefrom, including, without limitation,
any loss or cost in liquidating or employing deposits acquired to fund or
maintain the Eurodollar Advance; provided, however, that notwithstanding the
foregoing, the Borrower shall only be obligated to compensate such Lender for
any such amount arising or accruing during any time or period commencing not
more than 60 days prior to the date on which the Lender notifies the Borrower
that payment of such amount is owing to it by the Borrower.

         4.5.   Lender Statements; Survival of Indemnity. To the extent
reasonably possible, each Lender shall designate an alternate Lending
Installation with respect to its Eurodollar Loans to reduce any liability of
the Borrower to such Lender under Sections 4.1 and 4.2 or to avoid the
unavailability of Eurodollar Advances under Section 4.3, so long as such
designation is not disadvantageous to such Lender.  Each Lender shall deliver a
written statement of such Lender as to the amount due, if any, under Sections
4.1, 4.2 or 4.4.  Such written statement shall set forth in reasonable detail
the calculations upon which such Lender determined such amount and shall be
final, conclusive and binding on the Borrower in the absence of manifest error.
In determining such amount, such Lender may use any reasonable averaging and
attribution methods.  Determination of amounts payable under such Sections in
connection with a Eurodollar Loan shall be calculated as though each Lender
funded its Eurodollar Loan through the purchase of a deposit of the type and
maturity corresponding to the deposit used as a reference in determining the
Eurodollar Rate applicable to such Loan, whether in fact that is the case or
not.  Unless otherwise provided herein, the amount specified in the written
statement shall be payable on demand after receipt by the Borrower of the
written statement.  The obligations of the Borrower under Sections 4.1, 4.2 and
4.4 shall survive payment of the Obligations and termination of this Agreement.

         4.6.    Substitution of Lenders.   If, in respect of any Lender,
circumstances arise which would or would upon the giving of notice result in
(i) an increase in the liability of a Borrower to such Lender under Section 4.1
or 4.2, or (ii) the unavailability of Eurodollar Advances under Section 4.3,
and such Lender has been unable to take, or has not taken, steps to mitigate
the effect of the circumstances in question, such Lender shall be obliged, at
the request of the Borrower, pursuant to an Assignment Agreement, to sell its
Note and assign all its rights and obligations hereunder to another Person
nominated by the Borrower and willing to purchase such Note, assume the
Commitment of such Lender and participate in the facility in place of such
Lender; provided that such Person satisfies all of the requirements of this
Agreement, including, but not limited to, providing the forms required by
Section 2.18.  Upon such purchase and assumption by such substituted Person,
(a) such Person shall for all purposes be a Lender party to this Agreement and
any other Loan Document executed by the Lenders and shall have all the rights





                                      23
<PAGE>   30

and obligations of a Lender under the Loan Documents, to the same extent as if
it were an original party hereto, and (b) the transferor Lender shall be
released with respect to the Loans and Commitment so assigned.  Notwithstanding
any such assignment, unless otherwise agreed to by the transferor Lender, the
obligations of the Borrower under Sections 4.1, 4.2 and 4.3 shall survive any
such assignment and be enforceable by such transferor Lender.

                                   ARTICLE V

                              CONDITIONS PRECEDENT

         5.1.  Initial Advance.  The Lenders shall not be required to make the
initial Advance and, if the initial Advance shall not have been made, the
Issuing Bank shall not be obligated to issue any Facility Letter of Credit
hereunder unless the Borrower has furnished to the Agent with sufficient copies
for the Lenders the following items (and the date upon which all such items
shall have been so furnished is referred to as the "Effective Date"):

                 deemed necessary by counsel for any Lender) authorizing the
                 execution of the Loan Documents, which resolutions (i) were in

                 Borrower authorized to sign the Loan Documents (as of the
                 dates any such documents were signed) and to make borrowings
                 hereunder, upon which certificate the Agent and the Lenders
                 shall be entitled to rely until informed of any change in

                 officer of the Borrower, stating that on the Effective Date

      (x)        Such other documents as any Lender or its counsel may have

          5.2.   Each Advance or Issuance of a Facility Letter of Credit.  The
Lenders shall not be required to make any Advance (other than an Advance that,
after giving effect thereto and to the application of the proceeds thereof,
does not increase the aggregate amount of outstanding Advances) and the Issuing
Bank shall not be obligated to issue any Facility Letter of Credit, unless on
the applicable Borrowing Date or Issuance Date:

     (i)         There exists no Default or Unmatured Default.

     (ii)        The representations and warranties contained in Article VI are

                 representation or warranty (to the extent it relates to such
                 earlier date) shall be true and correct on and as of such
                 earlier date (other than the representation and warranty made

                 recent annual audited financial statements furnished to the
                 Lenders pursuant to Section 7.1(i) hereof).

         Each Borrowing Notice with respect to each such Advance and each
Letter of Credit Request with respect to each Facility Letter of Credit shall
constitute a representation and warranty by the Borrower that the conditions
contained in Sections 5.2(i) and (ii) have been satisfied.  Any Lender or
Issuing Bank may require a duly completed compliance certificate in
substantially the form of Exhibit "C" hereto as a condition to making an
Advance or issuing a Facility Letter of Credit.

                                   ARTICLE VI

                         REPRESENTATIONS AND WARRANTIES

         The Borrower represents and warrants to the Lenders that:

          6.1.   Corporate Existence and Standing.  Each of the Borrower and
its Subsidiaries is a corporation duly incorporated, validly existing and in
good standing under the laws of its jurisdiction of incorporation and has all
requisite authority to conduct its business in each jurisdiction in which its
business is conducted, except where the failure to have such authority could
not reasonably be expected to have a Material Adverse Effect.




                                      25
<PAGE>   32

          6.2.   Authorization and Validity.  The Borrower has the corporate
power and authority and legal right to execute and deliver the Loan Documents
and to perform its obligations thereunder.  The execution and delivery by the
Borrower of the Loan Documents and the performance of its obligations
thereunder have been duly authorized by all necessary corporate action, and the
Loan Documents constitute legal, valid and binding obligations of the Borrower
enforceable against the Borrower in accordance with their terms, except as
enforceability may be limited by bankruptcy, insolvency or similar laws
affecting the enforcement of creditors' rights generally.

          6.3.   No Conflict; Government Consent.  Neither the execution and
delivery by the Borrower of the Loan Documents, nor the consummation of the
transactions therein contemplated, nor compliance with the provisions thereof
will violate (i) any law, rule, regulation, order, writ, judgment, injunction,
decree or award binding on the Borrower or any of its Subsidiaries, (ii) the
Borrower's or any Subsidiary's articles of incorporation or by-laws or (iii) the
provisions of any indenture, instrument or agreement to which the Borrower or
any of its Subsidiaries is a party or is subject, or by which it, or its
Property, is bound, or conflict with or constitute a default thereunder, or
result in the creation or imposition of any Lien in, of or on the Property of
the Borrower or a Subsidiary pursuant to the terms of any such indenture,
instrument or agreement, other than, in the case of the foregoing clause (iii),
any such violations or defaults that, singly or in the aggregate, could not
reasonably be expected to have a Material Adverse Effect.  No order, consent,
approval, license, authorization, or validation of, or filing, recording or
registration with, or exemption by, any governmental or public body or
authority, or any subdivision thereof, which has not been obtained by the
Borrower or any Subsidiary, is required to authorize, or is required in
connection with the execution, delivery and performance of, or the legality,
validity, binding effect or enforceability of, any of the Loan Documents.

          6.4.   Financial Statements.  The December 31, l994 consolidated
financial statements of the Borrower and its Subsidiaries heretofore delivered
to the Lenders were prepared in accordance with generally accepted accounting
principles in effect on the date such statements were prepared and fairly
present the consolidated financial condition and operations of the Borrower and
its Subsidiaries at such date and the consolidated results of their operations
for the period then ended.

          6.5.   Material Adverse Change.  Since December 31, 1994, there has
been no change in the business, Property, condition (financial or otherwise) or
results of operations of the Borrower and its Subsidiaries which could

to be filed and have paid all taxes due pursuant to said returns or pursuant to
any assessment received by the Borrower or any of its Subsidiaries, except such
taxes, if any, as are being contested in good faith and as to which adequate
reserves have been provided.  The United States income tax returns of the
Borrower and its Subsidiaries have been audited by the Internal Revenue Service

of all of the presently existing Subsidiaries of the Borrower, setting forth
their respective jurisdictions of incorporation and the percentage of their
respective capital stock owned by the Borrower or other Subsidiaries.  All of
the issued and outstanding shares of capital stock of such Subsidiaries have
been duly authorized and issued and are fully paid and non-assessable.

          6.9.   ERISA.  There are no Unfunded Liabilities for any Single 
Employer Plans which could reasonably be expected to have a Material Adverse
Effect.  Neither the Borrower nor any other member of the Controlled Group has

occurred with respect to any Single Employer Plan, neither the Borrower nor any
other members of the Controlled Group has withdrawn from any Single Employer

reports furnished by the Borrower or any of its Subsidiaries to the Agent or to
any Lender in connection with the negotiation of, or compliance with, the Loan
Documents, taken as a whole and in light of the circumstances under which they
are made, do not contain any material misstatement of fact or omit to state a
material fact or any fact necessary to make the statements contained therein
not misleading as of the date made.

         6.11.   Regulation U.  Margin stock (as defined in Regulation U)
constitutes less than 25% of those assets of the Borrower and its Subsidiaries
which are subject to any limitation on sale, pledge, or other restriction
hereunder.

         6.12.   Material Agreements.  Except as set forth on Schedule "5"
hereto, neither the Borrower nor any Subsidiary is a party to any agreement or
instrument or subject to any charter or other corporate restriction which could
reasonably be expected to have a Material Adverse Effect.  Neither the Borrower
nor any Subsidiary is in default in the performance, observance or fulfillment
of any of the obligations, covenants or conditions contained in (i) any
agreement to which it is a party or (ii) any agreement or instrument evidencing
or governing Indebtedness, which default, in either case, could reasonably be
expected to have a Material Adverse Effect.

         6.13.   Compliance With Laws.  The Borrower and its Subsidiaries have
complied with all applicable statutes, rules, regulations, orders and
restrictions of any domestic or foreign government or any instrumentality or
agency thereof, having jurisdiction over the conduct of their respective
businesses or the ownership of their respective Property, except where the
failure to so comply could not reasonably be expected to have a Material
Adverse Effect.  Neither the Borrower nor any Subsidiary has received any
notice to the effect that its operations are not in material compliance with
any of the requirements of 




                                      27
<PAGE>   34

applicable federal, state and local environmental, health and safety statutes
and regulations or the subject of any federal or state investigation evaluating
whether any remedial action is needed to respond to a release of any toxic or
hazardous waste or substance into the environment, which non-compliance or
remedial action could reasonably be expected to have a Material Adverse Effect.
        
         6.14.   Ownership of Properties.  Except as set forth on Schedule "3"
hereto, on the date of this Agreement, the Borrower and its Subsidiaries will
have good title, free of all Liens other than those permitted by Section 7.17,
to all of the Property and assets reflected in the financial statements as
owned by it.

         6.15.   Investment Company Act.  Neither the Borrower nor any
Subsidiary thereof is an "investment company" or a company "controlled" by an
"investment company", within the meaning of the Investment Company Act of 1940,
as amended.

         6.16.   Public Utility Holding Company Act.  Neither the Borrower nor
any Subsidiary is a "holding company" or a "subsidiary company" of a "holding
company", or an "affiliate" of a "holding company" or of a "subsidiary company"
of a "holding company", within the meaning of the Public Utility Holding
Company Act of 1935, as amended.

         6.17.   Subordinated Indebtedness.  The Obligations constitute senior
indebtedness which is entitled to the benefits of the subordination provisions
of all outstanding Subordinated Indebtedness.

         6.18.   Insurance.  The certificate signed by the President or Chief
Financial Officer of the Borrower, that attests to the existence and adequacy
of, and summarizes, the property and casualty insurance program carried by the
Borrower and that has been furnished by the Borrower to the Agent and the
Lenders, is complete and accurate.

the Borrower or any of its Subsidiaries from discontinuing the maintenance,
preservation, protection or operation of any of its Property if such
discontinuance, as determined by Borrower or any such Subsidiary in the
exercise of its good faith business judgment, is desirable in the conduct of

discontinuance could not reasonably be expected to have a Material Adverse
Effect.

to cause, such Indebtedness to become due prior to its stated maturity; or any

the Borrower and its Subsidiaries so condemned, seized, appropriated, or taken
custody or control of, during the twelve-month period ending with the month in

                                   ARTICLE IX

                 ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

          9.1.   Acceleration.  If any Default described in Section 8.6 or 8.7
occurs with respect to the Borrower, the obligations of the Lenders to make
Loans and of the Issuing Bank to issue Facility Letters of Credit hereunder
shall automatically terminate and the Obligations shall immediately become due
and payable without any election or action on the part of the Agent or any
Lender.  If any other Default occurs, the Required Lenders may terminate or
suspend the obligations of the Lenders to make Loans and of the Issuing Bank to
issue Facility Letters of Credit hereunder, or declare the Obligations to be
due and payable, or both, whereupon the Obligations shall become immediately
due and payable, without presentment, demand, protest or notice of any kind,
all of which the Borrower hereby expressly waives.  In addition to the
foregoing following any acceleration of the Obligations as set forth above, so
long as any Facility Letter of Credit has not been fully drawn and has not been
cancelled or expired by its terms, upon demand by the Agent the Borrower shall
deposit in the Letter of Credit Collateral Account cash in an amount equal to
the aggregate undrawn face amount of all outstanding Facility Letters of Credit
and all fees and other amounts due or which may become due with respect
thereto.  The Borrower shall have no control over funds in the Letter of Credit
Collateral Account, which funds shall be invested by the Agent from time to
time in its discretion in certificates of deposit of First Chicago having a
maturity not exceeding thirty days.  Such funds shall be promptly applied by
the Agent to reimburse the Issuing Bank for drafts drawn from time to time
under the Facility Letters of Credit.  Such funds, if any, remaining in the
Letter of Credit Collateral Account following the payment of all Obligations in
full shall, unless the Agent is otherwise directed by a court of competent
jurisdiction, be promptly paid over to the Borrower.

          9.2.   Amendments.  Subject to the provisions of this Article IX, the
Required Lenders (or the Agent with the consent in writing of the Required
Lenders) and the Borrower may enter into agreements supplemental hereto for the
purpose of adding or modifying any provisions to the Loan Documents or changing
in any manner the rights of the Lenders or the Borrower hereunder or waiving
any Default hereunder; provided, however, that no such supplemental agreement
shall, without the consent of each Lender directly or indirectly affected
thereby:

         (i)     Extend the maturity of any Loan or Note or forgive all or any
                 portion of the principal amount thereof, or reduce the rate or
                 extend the time of payment of interest or fees thereon.

         (ii)    Reduce the percentage specified in the definition of Required
                 Lenders.

         (iii)   Extend the Termination Date, or reduce the amount or extend
                 the payment date for the mandatory payments required under
                 Section 2.7.2, or increase the amount of the Commitment of any
                 Lender hereunder, or permit the Borrower to assign its rights
                 under this Agreement.

         (iv)    Amend this Section 9.2 or Section 3.2, 3.4(b), 3.6(a), 8.6 or
                 8.7.




                                      39
<PAGE>   46
         (v)     Increase the maximum drawable amount or extend the expiration
                 date of any outstanding Facility Letter of Credit (other than
                 in accordance with Article III) or reduce the principal amount
                 of or extend the time of payment of any Reimbursement
                 Obligation or fee associated with any Facility Letter of
                 Credit.

         (vi)    Release any guarantor of any Obligations or, release all or
                 substantially all of the collateral, if any, securing the
                 Obligations.

No amendment of any provision of this Agreement relating to the Agent shall be
effective without the written consent of the Agent.  The Agent may waive
payment of the fee required under Section 13.3.2 without obtaining the consent
of any other party to this Agreement.

          9.3.   Preservation of Rights.  No delay or omission of the Lenders
or the Agent to exercise any right under the Loan Documents shall impair such
right or be construed to be a waiver of any Default or an acquiescence therein,
and the making of a Loan or the issuance of a Facility Letter of Credit
notwithstanding the existence of a Default or the inability of the Borrower to
satisfy the conditions precedent to such Loan or Facility Letter of Credit
shall not constitute any waiver or acquiescence.  Any single or partial
exercise of any such right shall not preclude other or further exercise thereof
or the exercise of any other right, and no waiver, amendment or other variation
of the terms, conditions or provisions of the Loan Documents whatsoever shall
be valid unless in writing signed by the Lenders required pursuant to Section
9.2, and then only to the extent in such writing specifically set forth.  All
remedies contained in the Loan Documents or by law afforded shall be cumulative
and all shall be available to the Agent and the Lenders until the Obligations
have been paid in full.

                                   ARTICLE X

                               GENERAL PROVISIONS

          10.1.  Survival of Representations.  All representations and
warranties of the Borrower contained in this Agreement shall survive delivery
of the Notes and the making of the Loans and the issuance of the Facility
Letters of Credit herein contemplated.

          10.2.  Governmental Regulation.  Anything contained in this Agreement
to the contrary notwithstanding, no Lender shall be obligated to extend credit
to the Borrower in violation of any limitation or prohibition provided by any
applicable statute or regulation.

          10.3.  Taxes.  Any taxes (excluding federal income taxes on the
overall net income of any Lender) or other similar assessments or charges made
by any governmental or revenue authority in respect of the Loan Documents shall
be paid by the Borrower, together with interest and penalties, if any.

          10.4.  Headings.  Section headings in the Loan Documents are for
convenience of reference only, and shall not govern the interpretation of any
of the provisions of the Loan Documents.

<PAGE>   47

          10.5.  Entire Agreement.  The Loan Documents embody the entire
agreement and understanding among the Borrower, the Agent and the Lenders and
supersede all prior agreements and understandings among the Borrower, the Agent
and the Lenders relating to the subject matter thereof.

          10.6.  Several Obligations; Benefits of this Agreement.  The
respective obligations of the Lenders hereunder are several and not joint and
no Lender shall be the partner or agent of any other (except to the extent to
which the Agent is authorized to act as such).  The failure of any Lender to
perform any of its obligations hereunder shall not relieve any other Lender
from any of its obligations hereunder.  This Agreement shall not be construed
so as to confer any right or benefit upon any Person other than the parties to
this Agreement and their respective successors and assigns.

          10.7.  Expenses; Indemnification.  The Borrower shall reimburse the
Agent for any reasonable costs, internal charges and out-of-pocket expenses
(including reasonable attorneys' fees and reasonable time charges of attorneys
for the Agent, which attorneys may be employees of the Agent) paid or incurred
by the Agent in connection with the amendment, modification, and administration
of the Loan Documents.  The Borrower also agrees to reimburse the Agent and the
Lenders for any reasonable costs, internal charges and out-of-pocket expenses
(including reasonable attorneys' fees and reasonable time charges of attorneys
for the Agent and the Lenders, which attorneys may be employees of the Agent or
the Lenders) paid or incurred by the Agent or any Lender in connection with the
collection and enforcement of the Loan Documents.  The Borrower further agrees
to indemnify the Agent and each Lender, its directors, officers and employees
against all losses, claims, damages, penalties, judgments, liabilities and
expenses (including, without limitation, all expenses of litigation or
preparation therefor whether or not the Agent or any Lender is a party thereto)
which any of them may pay or incur arising out of or relating to this
Agreement, the other Loan Documents, the transactions contemplated hereby or
the direct or indirect application or proposed application of the proceeds of
any Loan or the use or intended use of any Facility Letter of Credit hereunder
or the issuance or performance under or the participation in any Facility
Letter of Credit, except to the extent that any of the same arises or results
from the gross negligence or willful misconduct of any Lender or the Agent.
The obligations of the Borrower under this Section shall survive the
termination of this Agreement.

          10.8.  Numbers of Documents.  All statements, notices, closing
documents, and requests hereunder shall be furnished to the Agent with
sufficient counterparts so that the Agent may furnish one to each of the
Lenders.

          10.9.  Accounting.  Except as provided to the contrary herein, all
accounting terms used herein shall be interpreted and all accounting
determinations hereunder shall be made in accordance with Agreement Accounting
Principles.

         10.10.  Severability of Provisions.  Any provision in any Loan
Document that is held to be inoperative, unenforceable, or invalid in any
jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable, or
invalid without affecting the remaining provisions in that jurisdiction or the
operation, enforceability, or validity of that provision in any other
jurisdiction, and to this end the provisions of all Loan Documents are declared
to be severable.

         10.11.  Nonliability of Lenders.  The relationship between the
Borrower and the Lenders and the Agent shall be solely that of borrower and
lender.  Neither the Agent nor any Lender shall have any fiduciary
responsibilities to the Borrower.  Neither the Agent nor any Lender undertakes
any responsibility 




                                      41

to the Borrower to review or inform the Borrower of any matter in connection
with any phase of the Borrower's business or operations.
        
         10.12.  Interest.  It is the intention of the parties hereto to comply
strictly with applicable usury laws; accordingly, notwithstanding any provision
to the contrary in this Agreement, the Notes or in any of the Loan Documents
securing the payment hereof or otherwise relating hereto, in no event shall this
Agreement, the Notes or such other Loan Documents require or permit the payment,
charging, taking, reserving, or receiving of any sums constituting interest
under applicable laws which exceed the maximum nonusurious amount permitted by
such laws.  If any such excess interest is contracted for, charged, taken,
reserved, or received in connection with the Loans evidenced by the Notes or in
any of the Loan Documents securing the payment hereof or otherwise relating
hereto, or in any communication by Agent or the Lenders or any other person to
the Borrower or any other person, or in the event all or part of the principal
or interest thereof shall be prepaid or accelerated, so that under any of such
circumstances or under any other circumstance whatsoever the amount of interest
contracted for, charged, taken, reserved, or received on the amount of principal
actually outstanding from time to time under the Notes shall exceed the maximum
nonusurious amount of interest permitted by applicable usury laws, then in any
such event it is agreed as follows:  (i) the provisions of this paragraph shall
govern and control, (ii) any such excess shall be deemed an accidental and bona
fide error and canceled automatically to the extent of such excess, and shall
not be collected or collectible, (iii) any such excess which is or has been paid
or received notwithstanding this paragraph shall be credited against the then
unpaid principal balance of the Notes, or, if no principal balance is then
outstanding, refunded to the applicable Borrower, and (iv) the effective rate of
interest shall be automatically reduced to the maximum nonusurious rate allowed
under applicable laws as construed by courts having jurisdiction thereof or
hereof.  Without limiting the foregoing, all calculations of the rate of
interest contracted for, charged, taken, reserved, or received in connection
with the Notes or this Agreement which are made for the purpose of determining
whether such rate exceeds the maximum nonusurious rate shall be made to the
extent permitted by applicable laws by amortizing, prorating, allocating and
spreading during the period of the full term of the Loans, including all prior
and subsequent renewals and extensions, all interest at any time contracted for,
charged, taken, reserved, or received.  The terms of this paragraph shall be
deemed to be incorporated in every document and communication relating to the
Notes, the Loans or any other Loan Document.

         10.13.  CHOICE OF LAW.  THE LOAN DOCUMENTS (OTHER THAN THOSE
CONTAINING A CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS (AND NOT THE LAW OF CONFLICTS) OF THE STATE
OF ILLINOIS, BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS.

         10.14.  CONSENT TO JURISDICTION.  THE BORROWER HEREBY IRREVOCABLY
SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR
ILLINOIS STATE COURT SITTING IN CHICAGO IN ANY ACTION OR PROCEEDING ARISING OUT
OF OR RELATING TO ANY LOAN DOCUMENTS AND THE BORROWER HEREBY IRREVOCABLY AGREES
THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND
DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION IT MAY NOW OR
HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT
IN SUCH A COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM.  NOTHING HEREIN
SHALL LIMIT THE RIGHT OF THE AGENT OR ANY LENDER TO BRING PROCEEDINGS AGAINST
THE BORROWER IN THE COURTS OF ANY 




                                      42
<PAGE>   49

OTHER JURISDICTION.  ANY JUDICIAL PROCEEDING BY THE BORROWER AGAINST THE AGENT
OR ANY LENDER OR ANY AFFILIATE OF THE AGENT OR ANY LENDER INVOLVING, DIRECTLY OR
INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH
ANY LOAN DOCUMENT SHALL BE BROUGHT ONLY IN A COURT IN CHICAGO, ILLINOIS.

         10.15.  WAIVER OF JURY TRIAL.  THE BORROWER, THE AGENT AND EACH LENDER
HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR
INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY
WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT OR THE
RELATIONSHIP ESTABLISHED THEREUNDER.

         10.16.  Confidentiality.  The Agent and each Lender hereby agree to
treat as confidential all "Confidential Information" (hereinafter defined),
except that the Agent and each Lender may disclose Confidential Information (i)
to other Lenders, (ii) to Affiliates of the Lenders and to the directors,
officers and employees of the Agent, the Lenders and their respective
Affiliates, in each case to the extent required in the course of their
respective duties, (iii) to legal counsel, accountants, and other professional
advisors to the Agent, a Lender or a Transferee to the extent required in the
course of their respective duties, (iv) to regulatory officials having
jurisdiction over a Lender or its Affiliate in connection with any regular or
special audit or investigation, (v) to any Person as requested pursuant to or
as required by law, regulation, or legal process, (vi) to any Person in
connection with any legal proceeding to which the Agent or that Lender is a
party, and (vii) as permitted by Section 13.4; provided, however, that the
Agent and each Lender shall use its best efforts to ensure that any
Confidential Information disclosed pursuant to the foregoing clauses (ii),
(iii) and (vii) shall only be disclosed after such Person(s) shall have been
informed that the information should be treated in a confidential manner.  For
purposes hereof, "Confidential Information" shall mean information with respect
to the Borrower which is non-public, confidential or proprietary in nature
which the Agent or any Lender may receive from, or on behalf of, the Borrower
or any Subsidiary pursuant to this Agreement or any of the other Loan
Documents, except such information which was publicly known at or prior to the
time such information is provided to the Agent and/or any such Lender, as the
case may be, or which subsequent thereto becomes publicly known through no act
or omission by the Agent or any Lender or any Person acting on their behalf.

                                   ARTICLE XI

                                   THE AGENT

         11.1.   Appointment.  The First National Bank of Chicago is hereby
appointed Agent hereunder and under each other Loan Document, and each of the
Lenders irrevocably authorizes the Agent to act as the agent of such Lender.
The Agent agrees to act as such upon the express conditions contained in this
Article XI.  The Agent shall not have a fiduciary relationship in respect of
the Borrower or any Lender by reason of this Agreement.

         11.2.   Powers.  The Agent shall have and may exercise such powers
under the Loan Documents as are specifically delegated to the Agent by the
terms of each thereof, together with such powers as are reasonably incidental
thereto.  The Agent shall have no implied duties to the Lenders, or any
obligation 




                                      43
<PAGE>   50

to the Lenders to take any action thereunder except any action specifically
provided by the Loan Documents to be taken by the Agent.
        
         11.3.   General Immunity.  Neither the Agent nor any of its directors,
officers, agents or employees shall be liable to the Borrower, the Lenders or
any Lender for any action taken or omitted to be taken by it or them hereunder
or under any other Loan Document or in connection herewith or therewith except
for its or their own gross negligence or willful misconduct.

         11.4.   No Responsibility for Loans, Recitals, etc.  Neither the Agent
nor any of its directors, officers, agents or employees shall be responsible
for or have any duty to ascertain, inquire into, or verify (i) any statement,
warranty or representation made in connection with any Loan Document or any
borrowing hereunder; (ii) the performance or observance of any of the covenants
or agreements of any obligor under any Loan Document, including, without
limitation, any agreement by an obligor to furnish information directly to each
Lender; (iii) the satisfaction of any condition specified in Article V, except
receipt of items required to be delivered to the Agent; (iv) the validity,
effectiveness or genuineness of any Loan Document or any other instrument or
writing furnished in connection therewith; or (v) the value, sufficiency,
creation, perfection or priority of any interest in any collateral security.
The Agent shall have no duty to disclose to the Lenders information that is not
required to be furnished by the Borrower to the Agent at such time, but is
voluntarily furnished by the Borrower to the Agent (either in its capacity as
Agent or in its individual capacity).

         11.5.   Action on Instructions of Lenders.  The Agent shall in all
cases be fully protected in acting, or in refraining from acting, hereunder and
under any other Loan Document in accordance with written instructions signed by
the Required Lenders, and such instructions and any action taken or failure to
act pursuant thereto shall be binding on all of the Lenders and on all holders
of Notes.  The Agent shall be fully justified in failing or refusing to take
any action hereunder and under any other Loan Document unless it shall first be
indemnified to its satisfaction by the Lenders pro rata against any and all
liability, cost and expense that it may incur by reason of taking or continuing
to take any such action.

         11.6.   Employment of Agents and Counsel.  The Agent may execute any
of its duties as Agent hereunder and under any other Loan Document by or
through employees, agents, and attorneys-in-fact and shall not be answerable to
the Lenders, except as to money or securities received by it or its authorized
agents, for the default or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care.  The Agent shall be entitled to advice of
counsel concerning all matters pertaining to the agency hereby created and its
duties hereunder and under any other Loan Document.

         11.7.   Reliance on Documents; Counsel.  The Agent shall be entitled
to rely upon any Note, notice, consent, certificate, affidavit, letter,
telegram, statement, paper or document believed by it to be genuine and correct
and to have been signed or sent by the proper person or persons, and, in
respect to legal matters, upon the opinion of counsel reasonably selected by
the Agent, which counsel may be employees of the Agent.

         11.8.   Agent's Reimbursement and Indemnification.  The Lenders agree
to reimburse and indemnify the Agent ratably in proportion to their respective
Commitments (i) for any amounts not reimbursed by the Borrower for which the
Agent is entitled to reimbursement by the Borrower under the Loan Documents,
(ii) for any other expenses incurred by the Agent on behalf of the Lenders, in
connection with the preparation, execution, delivery, administration and
enforcement of the Loan Documents and (iii) 




                                      44
<PAGE>   51

for any liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind and nature
whatsoever which may be imposed on, incurred by or asserted against the Agent in
any way relating to or arising out of the Loan Documents or any other document
delivered in connection therewith or the transactions contemplated thereby, or
the enforcement of any of the terms thereof or of any such other documents,
provided that no Lender shall be liable for any of the foregoing to the extent
they arise from the gross negligence or willful misconduct of the Agent.  The
obligations of the Lenders under this Section 11.8 shall survive payment of the
Obligations and termination of this Agreement.
        
         11.9.   Rights as a Lender.  In the event the Agent is a Lender, the
Agent shall have the same rights and powers hereunder and under any other Loan
Document as any Lender and may exercise the same as though it were not the
Agent, and the term "Lender" or "Lenders" shall, at any time when the Agent is
a Lender, unless the context otherwise indicates, include the Agent in its
individual capacity.  The Agent may accept deposits from, lend money to, and
generally engage in any kind of trust, debt, equity or other transaction, in
addition to those contemplated by this Agreement or any other Loan Document,
with the Borrower or any of its Subsidiaries in which the Borrower or such
Subsidiary is not restricted hereby from engaging with any other Person.  The
Agent, in its individual capacity, is not obligated to remain a Lender.

         11.10.  Lender Credit Decision.  Each Lender acknowledges that it has,
independently and without reliance upon the Agent or any other Lender and based
on the financial statements prepared by the Borrower and such other documents
and information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement and the other Loan Documents.  Each
Lender also acknowledges that it will, independently and without reliance upon
the Agent or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions
in taking or not taking action under this Agreement and the other Loan
Documents.

         11.11.  Successor Agent.  The Agent may resign at any time by giving
written notice thereof to the Lenders and the Borrower, such resignation to be
effective upon the appointment of a successor Agent or, if no successor Agent
has been appointed, forty-five days after the retiring Agent gives notice of
its intention to resign.  Upon any such resignation, the Required Lenders shall
have the right to appoint, on behalf of the Lenders, a successor Agent
reasonably acceptable to the Borrower.  If no successor Agent shall have been
so appointed by the Required Lenders within thirty days after the resigning
Agent's giving notice of its intention to resign, then the resigning Agent may
appoint, on behalf of the Lenders, a successor Agent reasonably acceptable to
the Borrower.  If the Agent has resigned and no successor Agent has been
appointed, the Lenders may perform all the duties of the Agent hereunder and
the Borrower shall make all payments in respect of the Obligations to the
applicable Lender and for all other purposes shall deal directly with the
Lenders.  No successor Agent shall be deemed to be appointed hereunder until
such successor Agent has accepted the appointment.  Any such successor Agent
shall be either a Lender hereunder or a commercial bank organized under the
laws of the United States or any state thereof having capital and retained
earnings of at least $100,000,000.  Upon the acceptance of any appointment as
Agent hereunder by a successor Agent, such successor Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the resigning Agent.  Upon the effectiveness of the resignation of the
Agent, the resigning Agent shall be discharged from its duties and obligations
hereunder and under the Loan Documents.  After the effectiveness of the
resignation of an Agent, the provisions of this Article XI shall continue in
effect for the benefit of such Agent in respect of any actions taken or omitted
to be taken by it while it was acting as the Agent hereunder and under the
other Loan Documents.

                                  ARTICLE XII

                            SETOFF; RATABLE PAYMENTS

         12.1.   Setoff.  In addition to, and without limitation of, any rights
of the Lenders under applicable law, if the Borrower becomes insolvent, or any
Default or Unmatured Default occurs, any and all deposits (including all
account balances, whether provisional or final and whether or not collected or
available) and any other Indebtedness at any time held or owing by any Lender
to or for the credit or account of the Borrower may be offset and applied
toward the payment of the Obligations then due and payable to such Lender.

         12.2.   Ratable Payments.  If any Lender, whether by setoff or
otherwise, has payment made to it upon its share of any Advance or
Reimbursement Obligation (other than payments received pursuant to Sections
4.1, 4.2 or 4.4) in a greater proportion than that received by any other
Lender, such Lender agrees, promptly upon demand, to purchase a portion of that
Advance or Reimbursement Obligation held by the other Lenders so that after
such purchase each Lender will hold its ratable proportion that Advance or
Reimbursement Obligation.  If any Lender, whether in connection with setoff or
amounts which might be subject to setoff or otherwise, receives collateral or
other protection for its Obligations or such amounts which may be subject to
setoff, such Lender agrees, promptly upon demand, to take such action necessary
such that all Lenders share in the benefits of such collateral ratably in
proportion to their Loans.  In case any such payment is disturbed by legal
process, or otherwise, appropriate further adjustments shall be made.

                                  ARTICLE XIII

               BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

         13.1.   Successors and Assigns.  The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of the Borrower and
the Lenders and their respective successors and assigns, except that (i) the
Borrower shall not have the right to assign its rights or obligations under the
Loan Documents and (ii) any assignment by any Lender must be made in compliance
with Section 13.3.  Notwithstanding clause (ii) of this Section, any Lender may
at any time, without the consent of the Borrower or the Agent, assign all or
any portion of its rights under this Agreement and its Notes to a Federal
Reserve Bank; provided, however, that no such assignment shall release the
transferor Lender from its obligations hereunder.  The Agent may treat the
payee of any Note as the owner thereof for all purposes hereof unless and until
such payee complies with Section 13.3 in the case of an assignment thereof or,
in the case of any other transfer, a written notice of the transfer is filed
with the Agent.  Any assignee or transferee of a Note agrees by acceptance
thereof to be bound by all the terms and provisions of the Loan Documents.  Any
request, authority or consent of any Person, who at the time of making such
request or giving such authority or consent is the holder of any Note, shall be
conclusive and binding on any subsequent holder, transferee or assignee of such
Note or of any Note or Notes issued in exchange therefor.




                                      46
<PAGE>   53

         13.2.   Participations.

                 13.2.1.  Permitted Participants; Effect.  Any Lender may, in
         the ordinary course of its business and in accordance with applicable
         law, at any time sell to one or more banks or other entities
         ("Participants") participating interests in any Loan owing to such
         Lender, any Note held by such Lender, any interest in Facility Letters
         of Credit, any Commitment of such Lender or any other interest of such
         Lender under the Loan Documents.  In the event of any such sale by a
         Lender of participating interests to a Participant, such Lender's
         obligations under the Loan Documents shall remain unchanged, such
         Lender shall remain solely responsible to the other parties hereto for
         the performance of such obligations, such Lender shall remain the
         holder of any such Note for all purposes under the Loan Documents, all
         amounts payable by the Borrower under this Agreement shall be
         determined as if such Lender had not sold such participating
         interests, and the Borrower and the Agent shall continue to deal
         solely and directly with such Lender in connection with such Lender's
         rights and obligations under the Loan Documents.

                 13.2.2.  Voting Rights.  Each Lender shall retain the sole
         right to approve, without the consent of any Participant, any
         amendment, modification or waiver of any provision of the Loan
         Documents other than any amendment, modification or waiver with
         respect to any Loan, Facility Letter of Credit or Commitment in which
         such Participant has an interest which forgives principal, interest or
         fees or reduces the interest rate or fees payable with respect to any
         such Loan, Facility Letter of Credit or Commitment, postpones any date
         fixed for any regularly-scheduled payment of principal of, or interest
         or fees on, any such Loan, Facility Letter of Credit or Commitment,
         releases any guarantor of any such Loan or Facility Letter of Credit
         or releases any substantial portion of collateral, if any, securing
         any such Loan or Facility Letter of Credit.

                 13.2.3.  Benefit of Setoff.  The Borrower agrees that each
         Participant shall be deemed to have the right of setoff provided in
         Section 12.1 in respect of its participating interest in amounts owing
         under the Loan Documents to the same extent as if the amount of its
         participating interest were owing directly to it as a Lender under the
         Loan Documents, provided that each Lender shall retain the right of
         setoff provided in Section 12.1 with respect to the amount of
         participating interests sold to each Participant.  The Lenders agree
         to share with each Participant, and each Participant, by exercising
         the right of setoff provided in Section 12.1, agrees to share with
         each Lender, any amount received pursuant to the exercise of its right
         of setoff, such amounts to be shared in accordance with Section 12.2
         as if each Participant were a Lender.

         13.3.   Assignments.

                 13.3.1.  Permitted Assignments.  Any Lender may, in the
         ordinary course of its business and in accordance with applicable law,
         at any time assign to one or more banks or similar lending
         institutions ("Purchasers") all or any part of its rights and
         obligations under the Loan Documents pursuant to an assignment
         agreement substantially in the form of Exhibit "D" hereto or in such
         other form as may be agreed to by the parties thereto (the "Assignment
         Agreement").  The consent of the Borrower and the Agent shall be
         required prior to an assignment becoming effective with respect to a
         Purchaser which is not a Lender or an Affiliate thereof.  Such consent
         shall not be unreasonably withheld or delayed.




                                      47
<PAGE>   54

                 13.3.2.  Effect; Effective Date.  Upon (i) delivery to the
         Agent of a notice of assignment, substantially in the form attached as
         Annex "I" to Exhibit "D" hereto (a "Notice of Assignment"), together
         with any consents required by Section 13.3.1, and (ii) payment of a
         $2,500 fee to the Agent for processing such assignment, such
         assignment shall become effective on the effective date specified in
         such Notice of Assignment.  The Notice of Assignment shall contain a
         representation by the Purchaser to the effect that none of the
         consideration used to make the purchase of the Commitment, Facility
         Letters of Credit and Loans under the applicable assignment agreement
         are "plan assets" as defined under ERISA and that the rights and
         interests of the Purchaser in and under the Loan Documents will not be
         "plan assets" under ERISA.  On and after the effective date of such
         assignment, such Purchaser shall for all purposes be a Lender party to
         this Agreement and any other Loan Document executed by the Lenders and
         shall have all the rights and obligations of a Lender under the Loan
         Documents, to the same extent as if it were an original party hereto,
         and no further consent or action by the Borrower, the Lenders or the
         Agent shall be required to release the transferor Lender with respect
         to the Percentage of the Aggregate Commitment, Facility Letters of
         Credit and Loans assigned to such Purchaser.  Upon the consummation of
         any assignment to a Purchaser pursuant to this Section 13.3.2, the
         transferor Lender, the Agent and the Borrower shall make appropriate
         arrangements so that replacement Notes are issued to such transferor
         Lender and new Notes or, as appropriate, replacement Notes, are issued
         to such Purchaser, in each case in principal amounts reflecting their
         Commitment, as adjusted pursuant to such assignment.   In addition,
         within a reasonable time after the effective date of any assignment,
         the Agent shall, and is hereby authorized and directed to, revise
         Schedule "1" reflecting the revised Percentages of each of the Lenders
         and shall distribute such revised Schedule "1" to each of the Lenders
         and the Borrower and such revised Schedule "1" shall replace the old
         Schedule "1" and become part of this Agreement.
        
         13.4.   Dissemination of Information.  The Borrower authorizes each
Lender to disclose to any Participant or Purchaser or any other Person
acquiring an interest in the Loan Documents by operation of law (each a
"Transferee") and any prospective Transferee any and all information in such
Lender's possession concerning the creditworthiness of the Borrower and its
Subsidiaries; provided that each Transferee and prospective Transferee agrees
to be bound by Section 10.16.

         13.5.   Tax Treatment.  If any interest in any Loan Document is
transferred to any Transferee which is organized under the laws of any

                                                         _________________, 1995

To:  The First National Bank of Chicago, as Agent
     And the Lenders Identified in Schedule 1
     Attached Hereto

     Re:  Credit Agreement dated as of October 16, 1995 among
          Administaff, Inc., a Texas corporation, the Lenders Party
          Thereto and The First National Bank of Chicago, as Agent

Ladies and Gentlemen:

         Reference is made to the Credit Agreement (the "Credit Agreement")
dated as of October 16, 1995 among Administaff, Inc., a Texas corporation (the
"Borrower"), the Lenders party thereto and The First National Bank of Chicago,
as Agent, which Credit Agreement provides, among other things, for Advances in
an aggregate principal amount not to exceed US$10,000,000 at any one time
outstanding.  Capitalized terms used herein and not defined herein, if any,
shall have the meanings specified in the Credit Agreement.

         We have acted as special counsel to the Borrower in connection with
the execution and delivery of the Credit Agreement and the "Note" (hereinafter
defined).  This opinion is being delivered to you pursuant to Section 5.1(v) of
the Credit Agreement.

         For purposes of this opinion, we have examined:

         (a)     the Credit Agreement;

         (b)     that certain Note (the "Note"), dated October 16, 1995 in the
                 face amount of $10,000,000, executed by the Borrower and
                 payable to The First National Bank of Chicago.

         (c)     originals, or copies certified or otherwise identified to our
                 satisfaction, of such other documents, records, instruments
                 and certificates (collectively, the "Certificates") of
                 officers of the Borrower, public officials and others as we
                 have deemed necessary or appropriate to enable us to render
                 this opinion.

and have conducted such examination of law as we have deemed necessary or
appropriate to enable us to render this opinion.  (The documents referred to in
the foregoing clauses (a)-(b) shall be hereinafter collectively referred to as
the "Credit Documents.")

         In rendering our opinions set forth herein, we have assumed (i) the
genuineness of all signatures and of all documents submitted to us as
originals, (ii) that all copies submitted to us conform to the authentic
originals thereof, (iii) the legal capacity of all natural persons, (iv) that
each party to the Credit Documents (other than the Borrower) (w) is duly
organized, validly existing and in good standing under the laws of its
jurisdiction of organization, (x) has full power, authority and legal right
(corporate and




                                      54
<PAGE>   61
other) to execute, deliver and perform its respective obligations under the
Credit Documents and any other documents executed and delivered by it in
connection with the transactions contemplated by the Credit Agreement, (y) has
duly authorized by all requisite action, the execution, delivery and
performance of each of the Credit Documents and such other documents to which
it is a party, and (z) pursuant to such authority, has duly executed and
delivered the Credit Documents and such other documents by its duly authorized
officer, representative or agent and (v) that each of said documents
(including, without limitation, the Credit Documents) is valid, binding and
enforceable against each party thereto (other than the Borrower).

         In rendering our opinion, we have relied on (but have not
independently verified) the accuracy and completeness of (i) the
representations and warranties of the Borrower and Holdings contained in the
Credit Documents and (ii) the Certificates.

         Based on and subject to the foregoing, and further subject to the
other assumptions, qualifications and limitations hereinafter set forth, it is
our opinion that:

         1.      Each of the Borrower, [Specify Subsidiaries] is a corporation
and is validly existing and in good standing under the laws of its state of
incorporation.  Borrower is duly qualified to do business and is in good
standing as a foreign corporation in each of the jurisdictions of the United
States listed in Schedule 2 hereto, which jurisdictions, the Borrower has
advised us, are the only jurisdictions of the United States wherein Borrower
owns or leases any property or conducts any business and where the failure so
to so qualify could reasonably be expected to have a Material Adverse Effect.

         2.      The execution, delivery and performance by Borrower of each of
the Credit Documents have been duly authorized by all necessary corporate
action on the part of Borrower and do not (i) breach Borrwer's articles of
incorporation or bylaws or (ii) violate those laws of the State of Texas or
federal law which, based upon our experience, are applicable to transactions of
the character provided for in the Credit Agreement.

         3.      Each of the Credit Documents is the legal, valid and binding
obligation of Borrower, enforceable against it in accordance with its terms.

         4.      No material consent, approval or authorization of, or
declaration or filing with, any Texas State or United States of America federal
governmental authority is required to be obtained for the execution, delivery,
and performance by the Borrower of the Credit Documents.

         5.      The courts of the State of Texas and a Federal court sitting
in the State of Texas and applying the laws of the State of Texas in respect of
Section 10.14 of the Credit Agreement, in a properly argued and presented case,
should give effect to the choice of Illinois law set forth therein.

         Our opinions set forth hereinabove are qualified as follows:

         (a)     The opinions set forth in paragraph no. 1 above are based
solely on our review of certificates as of a recent date by public officials of
the applicable jurisdictions.

         (b)     Our opinion set forth in paragraph no. 3 above is limited by
each of the following:




                                      55
<PAGE>   62
                 (i)      applicable bankruptcy, reorganization, fraudulent
         conveyance, rearrangement, insolvency, moratorium and similar laws
         affecting the enforcement of creditors' rights generally as at the
         time in effect;

                 (ii)     general principles of equity, including, without
         limitation, concepts of materiality, reasonableness, good faith and
         fair dealing (regardless of whether considered in a proceeding in
         equity or at law); and

                 (iii)    the availability of equitable remedies' (regardless
         of whether considered in a proceeding at equity or at law), including,
         without limitation, specific enforcement and injunctive relief, being
         subject to the discretion of the court before which any proceedings
         therefor may be brought.

Further in regard to clause (ii) immediately above, we call to your attention
that we express no opinion as to the enforceability of the Credit Documents in
the event the Agent or any of the Lenders fail to act in good faith and in a
commercially reasonable manner.  Further, the interpretation and enforceability
of the Credit Documents or any provisions thereof are also subject to the
course of dealings between the parties and the applicable usage of trade.  In
this regard and without limiting the generality of the foregoing, you are
advised that pursuant to Section 1.205 of the Texas Business and Commerce Code
(the "Texas UCC") terms of an agreement covered thereby are to be interpreted
in consideration of commercial practices and other surrounding circumstances,
including a course of dealing between parties and usage of trade.

         Further, for purposes of rendering our opinion set forth in paragraph
no. 3 hereinabove, we have assumed that Texas law is the same as Illinois law
with respect to all matters affecting such opinion.

         (c)     In rendering our opinion set forth in paragraph no. 5
hereinabove, we are relying solely upon or reading of Section 35.51 of the
Texas UCC.  In this regard, we call your attention to the fact that said
Section 35.51 of the Texas UCC is new, and that we are not aware of any
interpretive case rulings in regard thereto.  Further, for purposes of
rendering such opinion, we have assumed that The First National Bank of Chicago
has its place of business (or if such party has more than one place of
business, its chief executive office or an office from which it conducted a
substantial part of the negotiations relating to the transaction contemplated
by the Credit Agreement), in the State of Illinois and that the Borrower is,
and during the term of the Credit Agreement will continue to be, required to
deliver payment of the Obligations in the State of Illinois and have relied on
such assumption.

         Further in regard to our opinion set forth in paragraph no. 5
hereinabove, we express no opinion with respect to choice of law in any action,
suit or proceeding in any forum other than the courts of the State of Texas or
the courts of the United States sitting in Texas.

         (d)      We express no opinion herein as to usury and matters
affecting usury.

         (e)     We express no opinion herein as to Section 13.2.3 of the
Credit Agreement or any similar provisions of any other of the Credit Documents
which purport to establish privity of contract.

         (f)     We express no opinion as to certain provisions of the Credit
Documents (including, without limitation Section 3.7 of the Credit Agreement),
to the extent such provisions purport to impose liability on the Credit 
Parties, and to relieve the Agent and the Lenders from liability, in respect of
payments made,



                                      56
<PAGE>   63
or the failure to make payments, under the Facility Letters of Credit in
violation or otherwise in conflict with the applicable provisions of the Texas
UCC.  In this regard, you are advised that Section 5.109 of the Texas UCC
requires the issuer of a letter of credit to examine documents with care so as
to ascertain that on their face they appear to comply with the terms of a letter
of credit, and Section 5.114 of the Texas UCC requires that an issuer honor a
draft which complies with the terms of the relevant letter of credit.
        
         (g)     We express no opinion herein with respect to any environmental
laws or regulation or any other environmental matters.

         (h)     We express no opinion herein with respect to the
enforceability of provisions of the Credit Documents which (i) purport to
restrict access to legal or equitable remedies or which relate to submission to
jurisdiction or venue of courts (including, without limitation, waivers of
forum non conveniens), (ii) any waivers of remedies, defenses, trial by jury or
other benefits bestowed by law or rights to notice, (iii) purport to establish
evidentiary standards for suits or proceedings to enforce any of the Credit
Documents or otherwise such as, for example, Sections 2.13 and 4.5 of the
Credit Agreement or which constitute consent judgments, (iv) relate to
severability, subrogation rights (or the waiver thereof), liquidated damages,
penalties, set-offs, whether or not in respect of obligations which have not
matured (or the waiver thereof), marshaling of assets, rights of third parties,
or ratifications of future acts, (v) relate to indemnification or exculpation
provisions, (vi) purport to limit the liability of any Person or which relate
to the delay or omission of enforcement of rights or remedies, (vii) purport to
preserve and maintain the validity of any obligation arising under any of the
Credit Documents despite such obligations' being unenforceable, invalid or
avoidable such as, for example, Section 3.7(a)(1) of the Credit Agreement,
(viii) contain any agreement to agree, (ix) purport to irrevocably appoint
attorneys-in-fact or other agents, (x) purport to require that all amendments
and waivers be in writing, (xi) purport to confer subject matter jurisdiction
in respect of bringing suit, enforcement of judgments or otherwise on any
court, or (xii) purport to require payments to be made without set-off,
deduction or counterclaim.

         The opinions expressed herein are as of the date hereof only, and we
assume no obligation, and expressly disclaim any obligation, to update or
supplement such opinions to reflect any fact or circumstance that may hereafter
come to our attention or any change in law that may hereafter occur or become
effective.  This opinion is limited to (i) the laws of the State of Texas and
(ii) to the extent applicable, the federal laws of the United States of
America, and we express no opinion as to the laws of any other jurisdiction.
Without limiting the generality of the foregoing, we are not authorized to
practice law in Illinois, have made no examination of Illinois law and express
no opinion in respect of the laws of Illinois or any matter governed by such
laws.  In this regard, we note that the Credit Documents provide that they are
to be governed by the laws of the State of Illinois.  This opinion is furnished
as of its date solely for the addressees hereof, the other Lenders, if any,
from time to time party to the Credit Agreement and any Participants pursuant
to Section 13.2.1 of the Credit Agreement and may not be relied upon by any
other Person, or by the Agent, such Lenders, or such Participants in any other
context without our express prior written consent.  Neither may this opinion be
quoted or in any way published or provided to any Person, in whole or in part,
without our express prior written consent.  This opinion is limited to the
matters expressed herein, and no opinions are intended to be implied, or may be
inferred, beyond those expressly stated herein.

                                        Very truly yours,

Ladies and Gentlemen:

         Reference is made to the Credit Agreement (the "Credit Agreement")
dated as of October 16, 1995 among Administaff, Inc., a Texas corporation (the
"Borrower"), the Lenders party thereto and The First National Bank of Chicago,

         I am the [Vice President and General Counsel] of the Borrower and am
rendering this opinion to you in such capacity and pursuant to Section 5.1(v)
of the Credit Agreement.

         For purposes of this opinion, I have reviewed:

                 officers of the Borrower, public officials and others as I
                 have deemed necessary or appropriate to enable us to render
                 this opinion

and have conducted such examination of law as I have deemed necessary or
appropriate to enable me to render this opinion.  (The documents referred to in
the foregoing clauses (a)-(b) shall be hereinafter collectively referred to as
the "Credit Documents.")

         In rendering my opinions set forth herein, I have assumed (i) the
genuineness of all signatures and of all documents submitted to me as
originals, (ii) that all copies submitted to me conform to the authentic
originals thereof and (iii) the authenticity of the originals of such latter
documents and have relied on, but have not independently verified, the accuracy
and completeness of the information contained in the documents examined by me.

         Based on and subject to the foregoing, and further subject to the
other assumptions, qualifications and limitations hereinafter set forth, it is
my opinion that:

         1.      The execution, delivery and performance by the Borrower of
each of the Credit Documents (i) do not violate any order, writ, judgment,
injunction decree or award binding on it or an of its Subsidiaries and or any
indenture, instrument or agreement binding upon it or any of its Subsidiaries,
(ii) will not result in, or require, the creation or imposition of any Lien
pursuant to the provisions of any indenture, instrument or agreement binding
upon it or any of its Subsidiaries, which violations or defaults or imposition
of Liens, singly or in the aggregate, could reasonably be expected to have a
Material Adverse Effect and (iii) will not require any consent of the
Borrower's shareholders.

         2.      The Credit Documents have been duly executed and delivered by
the Borrower.

         3.      Except as set forth in Schedule I hereto, there is no
litigation or proceeding pending against the Borrower or any of its
Subsidiaries which, if adversely determined, could reasonably be expected to
have a Material Adverse Effect.

         The opinions expressed herein are as of the date hereof only, and I
assume no obligation, and expressly disclaim any obligation, to update or
supplement such opinions to reflect any fact or circumstance that may hereafter
come to my attention or any change in law that may hereafter occur or become
effective.   This opinion is limited to the laws of the State of Texas and to
the extent applicable, the federal laws of the United States of America, and I
express no opinion as to the laws of any other jurisdiction.  Without limiting
the generality of the foregoing, I am not authorized to practice law in
Illinois, have made no examination of Illinois law and express no opinion in
respect of the laws of Illinois or any matter governed by such laws.  In this
regard, I note that the Credit Documents provide that they are to be governed
by the laws of the State of Illinois.  This opinion is furnished as of its date
solely for the addressees hereof, the other Lenders, if any, from time to time
party to the Credit Agreement and any Participants pursuant to Section 13.2.1
of the Credit Agreement and may not be relied upon by any other Person or by
the Agent, such Lenders or such Participants in any other context without my
express prior written consent.  Neither may this opinion be quoted or in any
way published or provided to any Person, in whole or in part, without my
express prior written consent.  This opinion is limited to the matters
expressed herein, and no opinions are intended to be implied, or may be
inferred, beyond those expressly stated herein.

                                        Sincerely,

attached hereto has been delivered to the Agent; provided, however that in no
event will the Effective Date occur if the payments required to be made by the
Assignee to the Assignor on the Effective Date under Sections 4 and 5 hereof
are not made on the proposed Effective Date.  Such Notice of Assignment must
include any consents required to be delivered to the Agent by Section 13.3.1 of
the Credit Agreement.  The Assignor will notify the Assignee of the proposed
Effective Date no later than the Business Day prior to the Effective Date.  As
of the Effective Date, (i) the Assignee shall have the rights and obligations
of a Lender under the Loan Documents with respect to the rights and obligations
assigned to the Assignee hereunder and (ii) the Assignor shall relinquish its
rights and be released from its corresponding obligations under the Loan
Documents with respect to the rights and obligations assigned to the Assignee
hereunder.

         4.  PAYMENTS OBLIGATIONS.  On and after the Effective Date, the
Assignee shall be entitled to receive from the Agent all payments of principal,
interest and fees with respect to the interest assigned hereby.  The Assignee
shall advance funds directly to the Agent with respect to all Loans and
reimbursement payments made on or after the Effective Date with respect to the
interest assigned hereby.  [In consideration for the sale and assignment of
Loans hereunder, (i) the Assignee shall pay the Assignor, on the Effective
Date, an amount equal to the principal amount of the portion of all Alternate
Base Rate Loans assigned to the Assignee hereunder and (ii) with respect to
each Eurodollar Loan made by the




                                      64
<PAGE>   71
Assignor and assigned to the Assignee hereunder which is outstanding on the
Effective Date, (a) on the last day of the Interest Period therefor or (b) on
such earlier date agreed to by the Assignor and the Assignee or (c) on the date
on which any such Eurodollar Loan either becomes due (by acceleration or
otherwise) or is prepaid (the date as described in the foregoing clauses (a),
(b) or (c) being hereinafter referred to as the "Payment Date"), the Assignee
shall pay the Assignor an amount equal to the principal amount of the portion
of such Eurodollar Loan assigned to the Assignee which is outstanding on the
Payment Date.  If the Assignor and the Assignee agree that the Payment Date for
such Eurodollar Loan shall be the Effective Date, they shall agree to the
interest rate applicable to the portion of such Loan assigned hereunder for the
period from the Effective Date to the end of the existing Interest Period
applicable to such Eurodollar Loan (the "Agreed Interest Rate") and any
interest received by the Assignee in excess of the Agreed Interest Rate shall
be remitted to the Assignor.  In the event interest for the period from the
Effective Date to but not including the Payment Date is not paid by the
Borrower with respect to any Eurodollar Loan sold by the Assignor to the
Assignee hereunder, the Assignee shall pay to the Assignor interest for such
period on the portion of such Eurodollar Loan sold by the Assignor to the
Assignee hereunder at the applicable rate provided by the Credit Agreement.  In
the event a prepayment of any Eurodollar Loan which is existing on the Payment
Date and assigned by the Assignor to the Assignee hereunder occurs after the
Payment Date but before the end of the Interest Period applicable to such
Eurodollar Loan, the Assignee shall remit to the Assignor the excess of the
prepayment penalty paid with respect to the portion of such Eurodollar Loan
assigned to the Assignee hereunder over the amount which would have been paid
if such prepayment penalty was calculated based on the Agreed Interest Rate.
The Assignee will also promptly remit to the Assignor (i) any principal
payments received from the Agent with respect to Eurodollar Loans prior to the
Payment Date and (ii) any amounts of interest on Loans and fees received from
the Agent which relate to the portion of the Loans assigned to the Assignee
hereunder for periods prior to the Effective Date, in the case of Alternate
Base Rate Loans or fees, or the Payment Date, in the case of Eurodollar Loans,
and not previously paid by the Assignee to the Assignor.]*  In the event that
either party hereto receives any payment to which the other party hereto is
entitled under this Assignment Agreement, then the party receiving such amount
shall promptly remit it to the other party hereto.

*Each Assignor may insert its standard payment provisions in lieu of the
payment terms included in this Exhibit.

         5.  FEES PAYABLE BY THE ASSIGNEE.  The Assignee shall pay to the
Assignor a fee on each day on which a payment of interest or fees is made under
the Credit Agreement with respect to the amounts assigned to the Assignee
hereunder (other than a payment of interest or fees for the period prior to the
Effective Date or, in the case of Eurodollar Loans, the Payment Date, which the
Assignee is obligated to deliver to the Assignor pursuant to Section 4 hereof).
The amount of such fee shall be the difference between (i) the interest or fee,
as applicable, paid with respect to the amounts assigned to the Assignee
hereunder and (ii) the interest or fee, as applicable, which would have been
paid with respect to the amounts assigned to the Assignee hereunder if each
interest rate was ___ of 1%  less than the interest rate paid by the Borrower
or if the fee was ___ of 1% less than the fee paid by the Borrower, as
applicable.  In addition, the Assignee agrees to pay ___% of the recordation
fee required to be paid to the Agent in connection with this Assignment
Agreement.

         6.  REPRESENTATIONS OF THE ASSIGNOR; LIMITATIONS ON THE ASSIGNOR'S
LIABILITY.  The Assignor represents and warrants that it is the legal and
beneficial owner of the interest being assigned by it hereunder and that such
interest is free and clear of any adverse claim created by the

shall be responsible for (i) the due execution, legality, validity,
enforceability, genuineness, sufficiency or collectability of any Loan

other Lenders a security interest in assets of the Borrower or any guarantor,

the Property, books or records of the Borrower, (vi) the validity,
enforceability, perfection, priority, condition, value or sufficiency of any
collateral securing or purporting to secure the Loans or the Facility Letters
of Credit or (vii) any mistake, error of judgment, or action taken or omitted
to be taken in connection with the Loans, the Facility Letters of Credit or the
other Loan Documents.

         7.      REPRESENTATIONS OF THE ASSIGNEE.  The Assignee (i) confirms

take such action as agent on its behalf and to exercise such powers under the
Loan Documents as are delegated to the Agent by the terms thereof, together
with such powers as are reasonably incidental thereto, (iv) agrees that it will
perform in accordance with their terms all of the obligations which by the
terms of the Loan Documents are required to be performed by it as a Lender, (v)
agrees that its payment instructions and notice instructions are as set forth
in the attachment to Schedule 1 and (vi) confirms that none of the funds,
monies, assets or other consideration being used to make the purchase and
assumption hereunder are "plan assets" as defined under ERISA and that its
rights, benefits and interests in and under the Loan Documents will not be
"plan assets" under ERISA, [and (vii) attaches the forms prescribed by the
Internal Revenue Service of the United States certifying that the Assignee is
entitled to receive payments under the Loan Documents without deduction or
withholding of any United States federal income taxes].*

*to be inserted if the Assignee or its Lending Installation through which it is
booking the Loans is not organized under the laws of the United States, or a
state thereof.

         8.  INDEMNITY.  The Assignee agrees to indemnify and hold the Assignor
harmless against any and all losses, costs and expenses (including, without
limitation, reasonable attorneys' fees) and liabilities incurred by the
Assignor in connection with or arising in any manner from the Assignee's
non-performance of the obligations assumed under this Assignment Agreement.

of the terms and conditions of the Loan Documents or any law, rule, regulation,
order, writ, judgment, 




                                      66

injunction or decree and that any consent required under the terms of the Loan
Documents has been obtained and (ii) unless the prior written consent of the
Assignor is obtained, the Assignee is not thereby released from its obligations
to the Assignor hereunder, if any remain unsatisfied, including, without
limitation, its obligations under [Sections 4, 5 and 8] hereof.
        
         10.  REDUCTIONS OF AGGREGATE COMMITMENT.  If any reduction in the
Aggregate Commitment occurs between the date of this Assignment Agreement and
the Effective Date, the percentage interest specified in Item 3 of Schedule 1
shall remain the same, but the dollar amount purchased shall be recalculated
based on the reduced Aggregate Commitment.

         11.  ENTIRE AGREEMENT.  This Assignment Agreement and the attached
Notice of Assignment embody the entire agreement and understanding between the
parties hereto and supersede all prior agreements and understandings between
the parties hereto relating to the subject matter hereof.

               [NAME OF ASSIGNEE] (the "Assignee")


               1.     We refer to that Credit Agreement (the "Credit
Agreement") described in Item 1 of Schedule 1 to the Assignment Agreement, a
copy of which is attached hereto ("Schedule 1").  Capitalized terms used herein
and not otherwise defined herein shall have the meanings attributed to them in
the Credit Agreement.

               2.     This Notice of Assignment (this "Notice") is given and
delivered to the Borrower and the Agent pursuant to Section 13.3.2 of the
Credit Agreement.

               3.     The Assignor and the Assignee have entered into an
Assignment Agreement, dated as of _____, 199_ (the "Assignment"), pursuant to
which, among other things, the Assignor has sold, assigned, delegated and
transferred to the Assignee, and the Assignee has purchased, accepted and
assumed from the Assignor the percentage interest specified in Item 3 of
Schedule 1 of all outstandings, rights and obligations under the Credit
Agreement relating to the facilities listed in Item 3 of Schedule 1.  The
Effective Date of the Assignment shall be the later of the date specified in
Item 5 of Schedule 1 or two Business Days (or such shorter period as agreed to
by the Agent) after this Notice of Assignment and any consents and fees
required by Sections 13.3.1 and 13.3.2 of the Credit Agreement have been
delivered to the Agent, provided that the Effective Date shall not occur if any
condition precedent agreed to by the Assignor and the Assignee has not been
satisfied.

               4.     The Assignor and the Assignee hereby give to the Borrower
and the Agent notice of the assignment and delegation referred to herein.  The
Assignor will confer with the Agent before the date specified in Item 5 of
Schedule 1 to determine if the Assignment Agreement will become effective on
such date pursuant to Section 3 hereof, and will confer with the Agent to
determine the Effective Date pursuant 




                                      71
<PAGE>   78

to Section 3 hereof if it occurs thereafter.  The Assignor shall notify the
Agent if the Assignment Agreement does not become effective on any proposed
Effective Date as a result of the failure to satisfy the conditions precedent
agreed to by the Assignor and the Assignee.   At the request of the Agent, the
Assignor will give the Agent written confirmation of the satisfaction of the
conditions precedent.
        
               5.     The Assignor or the Assignee shall pay to the Agent on or
before the Effective Date the processing fee of $2,500 required by Section
13.3.2 of the Credit Agreement.

               6.     If Notes are outstanding on the Effective Date, the
Assignor and the Assignee request and direct that the Agent prepare and cause
the Borrower to execute and deliver new Notes or, as appropriate, replacements
notes, to the Assignor and the Assignee.  The Assignor and, if applicable, the
Assignee each agree to deliver to the Agent the original Note received by it
from the Borrower upon its receipt of a new Note in the appropriate amount.

               7.     The Assignee advises the Agent that notice and payment
instructions are set forth in the attachment to Schedule 1.

               8.     The Assignee hereby represents and warrants that none of
the funds, monies, assets or other consideration being used to make the
purchase pursuant to the Assignment are "plan assets" as defined under ERISA
and that its rights, benefits, and interests in and under the Loan Documents
will not be "plan assets" under ERISA.

               9.     The Assignee authorizes the Agent to act as its agent
under the Loan Documents in accordance with the terms thereof.  The Assignee
acknowledges that the Agent has no duty to supply information with respect to
the Borrower or the Loan Documents to the Assignee until the Assignee becomes a
party to the Credit Agreement.*

*May be eliminated if Assignee is a party to the Credit Agreement prior to the
Effective Date.

                                  EXHIBIT "F"

                                    GUARANTY

         The undersigned hereby requests the Lenders, under and as defined in
that certain Credit  Agreement, dated as of October 16, 1995 (as amended or
modified and in effect from time to time, the "Credit Agreement"), by and among
such Lenders, The First National Bank of Chicago, as agent for the Lenders (the
"Agent") and Administaff, Inc., a Texas corporation (the "Borrower"), through
any of their branches, offices, subsidiaries or affiliates as permitted by the
Credit Agreement, to extend credit or to permit credit to remain outstanding to
the Borrower under and pursuant to the Credit Agreement, and, in consideration
of any credit so granted or continued, the undersigned hereby absolutely and
unconditionally guarantees prompt payment when due, whether at stated maturity,
upon acceleration or otherwise, and at all times thereafter, of any and all
existing and future indebtedness and liability of every kind, nature and
character, direct or indirect, absolute or contingent (including all renewals,
extensions and modifications thereof and all reasonable attorneys' fees
incurred by the Agent and the Lenders in connection with the collection or
enforcement thereof), of the Borrower to the Agent and the Lenders under the
Credit Agreement howsoever and whensoever created, arising, evidenced or
acquired (the "Guaranteed Debt").

         The undersigned waives notice of the acceptance of this Guaranty and
of the extension or continuation of the Guaranteed Debt or any part thereof.
The undersigned further waives presentment, protest, notice, demand or action
on delinquency in respect of the Guaranteed Debt or any part thereof, including
any right to require the Lenders to sue the Borrower, any other guarantor or
any other person obligated with respect to the Guaranteed Debt or any part
thereof, or otherwise to enforce payment thereof against any collateral
securing the Guaranteed Debt or any part thereof.  The undersigned hereby
agrees that, if at any time any payment of any portion of the Guaranteed Debt
is rescinded or must otherwise be restored or returned upon the insolvency,
bankruptcy or reorganization of the Borrower or otherwise, the undersigned's
obligations hereunder with respect to such payment shall be reinstated at such
time as though such payment had not been made and whether or not the Agent or
any of the Lenders are in possession of this Guaranty.

         This Guaranty shall continue in effect until receipt by the Agent and
the Lenders of written notice of its termination and, notwithstanding such
receipt, thereafter as to Guaranteed Debt incurred, arising or committed for
prior to receipt by the Agent and the Lenders of such notice of termination,
including any extensions, modifications, renewals or indulgences with respect
to, or substitutions for, such Guaranteed Debt or any part thereof.

         The validity and enforceability of this Guaranty shall not be impaired
or affected by any of the following, whether occurring before or after receipt
by the Agent and the Lenders of notice of termination of this Guaranty: (a) any
extension, modification or renewal of, or indulgence with respect to, or
substitutions for, the Guaranteed Debt or any part thereof or any agreement
relating thereto at any time; (b) any change in the interest rate payable on,
or fees, commissions or other amounts payable with respect to, the Guaranteed
Debt; (c) any failure or omission to enforce any right, power or remedy with
respect to the Guaranteed Debt or any part thereof or any agreement relating
thereto, or any collateral, if any, securing the Guaranteed Debt or any part
thereof; (d) any waiver of any right, power or remedy or of any




                                      75
<PAGE>   82
default with respect to the Guaranteed Debt or any part thereof or any agreement
relating thereto or with respect to any collateral, if any, securing the
Guaranteed Debt or any part thereof; (e) any release, surrender, compromise,
settlement, waiver, subordination or modification, with or without
consideration, of any collateral, if any, securing the Guaranteed Debt or any
part thereof, any other guaranties with respect to the Guaranteed Debt or any
part thereof, or any other obligation of any person or entity with respect to
the Guaranteed Debt or any part thereof; (f) the enforceability or validity of
the Guaranteed Debt or any part thereof or the genuineness, enforceability or
validity of any agreement relating thereto or with respect to any collateral, if
any, securing the Guaranteed Debt or any part thereof; (g) the application of
payments received from any source to the payment of indebtedness other than the
Guaranteed Debt, any part thereof or amounts which are not covered by this
Guaranty even though the Lenders might lawfully have elected to apply such
payments to any part or all of the Guaranteed Debt or to amounts which are not
covered by this Guaranty; (h) any change of ownership of the Borrower or the
insolvency, bankruptcy or any other change in the legal status of the Borrower
(or the retirement or death of any partner or the introduction of any other
partner); (i) the change in or the imposition of any law, decree, regulation or
other governmental act which does or might impair, delay or in any way affect
the validity, enforceability or the payment when due of the Guaranteed Debt; (j)
the failure of the Borrower or the undersigned to maintain in full force,
validity or effect or to obtain or renew when required all governmental and
other approvals, licenses or consents required in connection with the Guaranteed
Debt or this Guaranty, or to take any other action required in connection with
the performance of all obligations pursuant to the Guaranteed Debt or this
Guaranty; or (k) the existence of any claim, setoff or other rights which the
undersigned may have at any time against the Borrower in connection herewith or
with any unrelated transaction, all whether or not the undersigned shall have
had notice or knowledge of any act or omission referred to in the foregoing
clauses (a) through (k) of this paragraph.  It is agreed that the undersigned's
liability hereunder is several and independent of any other guaranties or other
obligations at any time in effect with respect to the Guaranteed Debt or any
part thereof and that the undersigned's liability hereunder may be enforced
regardless of the existence, validity, enforcement or non-enforcement of any
such other guaranties or other obligations.
        
         The undersigned hereby represents and warrants to the Agent and the
Lenders that:  (a) the undersigned is duly organized, validly existing, and in
good standing under the laws of the jurisdiction in which the undersigned is
organized and has the power and authority and legal right to execute and
deliver this Guaranty and to perform the undersigned's obligations hereunder;
(b) the execution and delivery by the undersigned of this Guaranty and the
performance of the undersigned's obligations hereunder have been duly
authorized by all required action, and this Guaranty constitutes the legal,
valid and binding obligation of the undersigned, enforceable against the
undersigned in accordance with its terms, except as enforceability may be
limited by bankruptcy, insolvency or similar laws affecting the enforcement of
creditors' rights generally; (c) neither the execution and delivery of this
Guaranty nor the performance of the obligations of the undersigned hereunder
will violate (i) any law, decree, regulation, order or judgment binding on the
undersigned, (ii) the charter documents or by-laws of the undersigned, or (iii)
the provisions of any indenture, instrument or agreement to which the
undersigned is a party or is subject, other than, in the case of clause (iii)
any such violations or defaults that, singly or in the aggregate, could not
reasonably be expected to have a Material Adverse Effect; and (d) all consents,
approvals and authorizations and all filing requirements necessary for the
execution, delivery and performance of this Guaranty by the undersigned have
been obtained or complied with in full.

         Credit under the Credit Agreement may be granted or continued from
time to time by the Lenders to the Borrower without notice to or authorization
from the undersigned regardless of the Borrower's 




                                      76
<PAGE>   83

financial or other condition at the time of any such grant or continuation. 
Neither the Agent nor any of the Lenders shall have any obligation to disclose
or discuss with the undersigned its assessment of the financial condition of the
Borrower.
        
         Until the Guaranteed Debt is paid in full, the undersigned shall not
exercise any right of subrogation with respect to payments made by the
undersigned pursuant to this Guaranty.  The undersigned waives any benefit of
the collateral, if any, which may from time to time secure the Guaranteed Debt
or any part thereof and authorizes the Lenders to take any action or exercise
any remedy with respect thereto, which the Lenders in their sole discretion
shall determine, without notice to the undersigned.

         The undersigned agrees that all payments under this Guaranty shall be
made in the same currency and manner as provided for in the Credit Agreement.
The undersigned shall pay all sums due under this Guaranty free and clear of
and without deduction for, or on account of, any set-off or counterclaim or any
and all present or future taxes, levies, imposts, charges, fees, deductions or
withholdings.  If any sums payable hereunder shall be or become subject to any
such deduction or withholding, the amount of such payments shall be increased
so that the net amount received by the Lenders shall equal the amount which,
but for such deduction or withholding, would have been received by the Lenders
hereunder.

         Without limiting the rights of the Lenders under applicable law, the
undersigned authorizes each Lender to apply or offset any sums standing to the
credit of the undersigned with any office, branch, subsidiary or affiliate of
any such Lender to the payment when due of any amount owing by the undersigned
under this Guaranty.

         No provision of this Guaranty may be amended, supplemented or
modified, or any of the terms and provisions hereof waived, except by a written
instrument executed by the Agent, on behalf of the Lenders, and the
undersigned.  No failure on the part of the Agent or the Lenders to exercise,
and no delay in exercising, any right hereunder shall operate as a waiver
thereof; nor shall any single or partial exercise of any right hereunder
preclude any other or further exercise thereof or the exercise of any other
right.  The remedies herein provided are cumulative and not exclusive of any
remedies provided by law.

         The undersigned shall pay all reasonable costs, fees and expenses
(including reasonable attorneys' fees) incurred by the Agent and the Lenders in
collecting or enforcing the undersigned's obligations under this Guaranty.

         The provisions of this Guaranty are severable, and in any action or
proceeding involving any state corporate law, or any state or federal
bankruptcy, insolvency, reorganization or other law affecting the rights of
creditors generally, if the obligations of the undersigned hereunder would
otherwise be held or determined to be avoidable, invalid or unenforceable on
account of the amount of the undersigned's liability under this Guaranty, then,
notwithstanding any other provision of this Guaranty to the contrary, the
amount of such liability shall, without any further action by the undersigned,
the Agent or the Lenders, be automatically limited and reduced to the highest
amount which is valid and enforceable as determined in such action or
proceeding.




                                      77

         This Guaranty shall (i) bind the undersigned and the heirs, personal
representatives, successors and assigns of the undersigned, (ii) inure to the
benefit of the Agent, the Lenders, and their respective  successors and assigns
and (iii) be governed by the internal laws of the State of Illinois.  The
undersigned hereby irrevocably submits to the non-exclusive jurisdiction of any
United States federal or Illinois state court sitting in Chicago in any action
or proceeding arising out of or relating to this Guaranty, and the undersigned
hereby irrevocably agrees that all claims in respect of such action or
proceeding may be heard and determined in any such court.  THE UNDERSIGNED
HEREBY WAIVES ANY RIGHT TO A JURY TRIAL IN ANY ACTION ARISING HEREUNDER.

                               SUBORDINATED NOTE


$___________________                                          __________, 199_


         FOR VALUE RECEIVED, Administaff of Texas, Inc. (f/k/a Administaff,
Inc.), a Texas corporation (the Company"), hereby promises to pay to the order
of Administaff, Inc. (f/k/a Administaff of Delaware, Inc.), a Delaware
corporation ("Holder"), on the dates and in the manner set forth below, the
principal amount of ___________ Dollars ($________) (the "Principal Amount"),
with interest from _____________ on the balance thereof remaining unpaid from
time to time at the rate per annum equal to __________.

         This Note shall be due and payable as follows:

         [Describe Payment Schedule for Interest]

         [Describe Payment Schedule for Principal]

         This Note evidences some or all of the Holdings Subordinated Debt
referred to in the Credit Agreement (as defined in Section 1 below), and each
holder of this Note, by its acceptance hereof, agrees to the following
additional terms and conditions:

         1.    Definitions.  As used in this Note, the following terms shall
               mean:

               1.1.   "Credit Agreement" -- The Credit Agreement dated as of
October 16, 1995 by and between The First National Bank of Chicago ("First
Chicago"), as agent to a group of lenders (such lenders, including First
Chicago, are referred to herein, as the "Lenders" or the "holders of Senior
Debt") and the Company.

               1.2.   "Senior Debt" -- The aggregate of (i) the Company's
indebtedness to the Lenders incurred in connection with the transactions
governed by the Credit Agreement, but in no event to exceed a principal balance
of $10,000,000, (ii) any and all refinancings, renewals and extensions thereof
and (iii) all interest and other fees, costs, charges and expenses of any and
every nature whatsoever (including without limitation legal fees) from time to
time payable by the Company pursuant to the terms of the Credit Agreement.

         2.    Method of Payment.  All payments due under this Note shall be
paid to Holder at _________________, Attn: _____________ or such other address
or in such other manner as Holder designates to the Company.

         3.    Subordination.

               3.1.   Agreement to Subordinate.  Holder agrees that the
indebtedness evidenced by this Note is subordinated in right of payment, to the
extent and in the manner provided in this Section 3, to the




                                      79
<PAGE>   86

prior payment of all Senior Debt and that such subordination is for the benefit
of the holders of Senior Debt.
        
               3.2.   Liquidation, Dissolution, Bankruptcy.  Upon any payment
or any distribution of the assets of the Company to creditors upon a total or
partial liquidation or a total or partial dissolution of the Company or in a
bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to the  Company or its property:

                      (a)          the holders of Senior Debt shall be entitled
         to receive payments in full of the Senior Debt before Holder shall be
         entitled to receive any payment of Principal of or interest on this
         Note; and

                      (b)          until the Senior debt is paid in full, any
         distribution to which Holder would be entitled but for this Section 3
         shall be made to holders of Senior Debt as their interests may appear,
         except that Holder may receive shares of stock and other equity
         interests and any debt securities that are subordinated to Senior Debt
         to at least the same extent as this Note.

               3.3.   Default on Senior Debt.  The Company may not pay (or
offset or direct Holder to offset) any payment of principal of or interest on
this Note and may not repurchase, redeem or otherwise retire this Note
(collectively, "pay this Note") if at such time (i) any Senior Debt has not
been paid when due or (ii) any other default under the Credit Agreement has
occurred with respect to any Senior Debt pursuant to which the maturity thereof
may be accelerated immediately without further notice (except such notice as
may be required to effect such acceleration) and the expiration of any
applicable grace periods unless, in either case, the default has been cured or
waived; provided, however, that the Company may pay this Note without regard to
the foregoing if the Company receives written notice approving such payment
from the holders of Senior Debt; provided, further, that the foregoing
notwithstanding Holder may, in any event, receive shares of stock and other
equity interests and any debt securities (which are subordinated to Senior Debt
to at least the same extent as this Note) in payment of this Note.

               3.4.   Acceleration of Payment of Note.  If the maturity of this
Note is accelerated because of an Event of Default (as hereinafter defined),
the Company and Holder shall promptly notify the holders of the Senior Debt (if
any) of such acceleration.  If any Senior Debt is then outstanding, the Company
may not pay this Note until ten days after First Chicago, as agent for the
holders of Senior Debt, receives such notice and thereafter the Company may pay
this Note only if this Section 3 otherwise permits the payment at that time;
provided, that the foregoing notwithstanding Holder may, in any event, receive
shares of stock and other equity interests and any debt securities (which are
subordinated to Senior Debt to at least the same extent as this Note) in
payment of this Note.

               3.5.   When Distribution Must be Paid Over.  If a distribution
is made to Holder that because of this Section 3 should not have been made to
it, Holder shall hold such distribution in trust for the holders of Senior Debt
and pay it over to them as instructed by the holders of Senior Debt.

               3.6.   Subrogation.  After all Senior Debt is paid in full and
until Holder is paid in full, Holder shall be subrogated to the rights of the
holders of Senior debt to receive distributions applicable to Senior Debt.  A
distribution made under this Section 3 to the holders of Senior Debt that
otherwise would have been made to Holder is not, as between the Company and
Holder, a payment by the Company on Subordinated Debt.




                                      80
<PAGE>   87
               3.7.   Relative Rights.  This Section 3 defines the relative
rights of Holder and the holders of Senior Debt.  Nothing in this Note shall:

                      (a)          impair, as between the Company and Holder,
         the obligation of the Company, which is absolute and unconditional, to
         pay all amounts due hereon, including principal and interest in
         accordance with the terms hereof; or

                      (b)          prevent Holder from exercising its available
         remedies upon the occurrence of an Event of Default (hereinafter
         defined), subject to the rights of the holders of Senior Debt to
         receive in accordance with Section 3.2 hereof distributions otherwise
         payable to Holder.

               3.8.   Subordination May Not be Impaired.  No right of any
holder of Senior Debt to enforce the subordination of the indebtedness
evidenced hereby shall be impaired by any act or failure to act by the Company
or by its failure to comply with this Note.

               3.9.   Distribution or Notice to First Chicago.  Whenever a
distribution is to be made to the Lenders pursuant to Section 3.2 or 3.5 hereof
or a notice given to the holders of Senior Debt pursuant to Section 3.4 hereof,
the distribution may be made and the notice given to First Chicago as agent for
the Lenders.

               3.10.  Section 3 Not to Prevent Events of Default or Limit Right
to Accelerate.  The failure to make a payment pursuant to this Note by reason
of any provision in this Section 3 shall not be construed as preventing the
occurrence of an Event of Default (as defined in Section 4).  Nothing in this
Section 3 (except, as between Holder and the holders of Senior Debt only,
Holder's requirement to provide notice pursuant to Section 3.4) shall have any
effect on the right of Holder to accelerate the maturity of this Note.

               3.11.  Reliance by Holders of Senior Debt on Subordination
Provisions.  Holder, by accepting this Note, acknowledges and agrees that the
foregoing subordination provisions are, and are intended to be, an inducement
and a consideration to each holder of any Senior Debt, whether such Senior Debt
was created or acquired before or after the issuance hereof, to acquire and
continue to hold, or to continue to hold, such Senior Debt and such holder of
Senior debt shall be deemed conclusively to have relied on such subordination
provisions in acquiring and continuing to hold, or in continuing to hold, such
Senior Debt.

         4.    Events of Default.  The occurrence of any of the following
events of default (individually, an "Event of Default" and, collectively, the
"Events of Default") shall at the option of Holder make all sums of Principal
and accrued but unpaid interest then remaining unpaid and all other amounts
payable under this Note immediately due and payable, without demand,
presentment, notice or protest, all of which hereby are expressly waived,
anything herein or in any other agreement, contract, document or instrument
contained to the contrary notwithstanding and, subject to the provisions of
Section 3 hereof, Holder may immediately, and without expiration of any
additional period of grace, enforce payment of all liabilities of the Company
under this Note and exercise any other right available to it, at law or in
equity, all of which rights and powers may be exercised cumulatively and not
alternatively:

               4.1.   Nonpayment of principal hereunder when due, or nonpayment
of interest hereunder or of any fee or other obligations hereunder within five
days after the same becomes due.




                                      81
<PAGE>   88
               4.2.   The Company or any of its Subsidiaries (as defined in the
Credit Agreement) shall (i) have an order for relief entered with respect to it
under the Federal bankruptcy laws as now or hereafter in effect, (ii) make an
assignment for the benefit of creditors, (iii) apply for, seek, consent to, or
acquiesce in, the appointment of a receiver, custodian, trustee, examiner,
liquidator or similar official for it or any Substantial Portion (as defined in
the Credit Agreement) of its property, (iv) institute any proceeding seeking an
order for relief under the Federal bankruptcy laws as now or hereafter in
effect or seeking to adjudicate it a bankrupt or insolvent, or seeking
dissolution, winding up, liquidation, reorganization, arrangement, adjustment
or composition of it or its debts under any law relating to bankruptcy,
insolvency or reorganization or relief of debtors or fail to file an answer or
other pleading denying the material allegations of any such proceeding filed
against it, (v) take any corporate action to authorize or effect any of the
foregoing actions set forth in this Section 4.2 or (vi) fail to contest in good
faith any appointment or proceeding described in Section 4.3 prior to the last
day on which the filing of a response thereto is required to be made under
applicable law.

               4.3.   Without the application, approval or consent of the
Company or any of its Subsidiaries, a receiver, trustee, examiner, liquidator
or similar official shall be appointed for the Company or any of its
Subsidiaries or any part of its property which constitutes a Substantial
Portion (as defined in the Credit Agreement), or a proceeding described in
Section 4.2(iv) shall be instituted against the Company or any of its
Subsidiaries and such appointment continues undischarged or such proceeding
continues undismissed or unstayed for a period of 60 consecutive days.

               4.4.   The occurrence of any default on the Senior Debt pursuant
to which the maturity of the Senior Debt is accelerated in accordance with its
terms.

         5.    Miscellaneous.

               5.1.   Failure or Indulgency Not Waiver.  No failure or delay on
the part of Holder in the exercise of any power, right or privilege hereunder
shall operate as a waiver thereof, nor shall any one or more of such failures
or delays constitute a course of performance or dealing on which the Company is
entitled to rely, nor shall any single or partial exercise of any such power,
right or privilege preclude other or further exercise thereof or of any other
right, power or privilege.  All rights and remedies existing hereunder are
cumulative to, and not exclusive of, any rights or remedies otherwise
available.  The Company hereby consents to renewals and extensions of the time
of payment hereof, whether prior to or after the maturity hereof, without
notice, and hereby waives diligence, presentment, protest, demand and every
other notice of every kind.

               5.2.   Cost of Collection.  If any default is made in the
payment of Principal or interest under this Note, the Company shall pay Holder
hereof all costs incurred by Holder in the enforcement of its rights hereunder,
including without limitation costs of collection, reasonable attorneys' and
accountants' fees and costs of appeals.

               5.3.   Governing Law.  This Note shall be governed by the laws
of the State of Illinois.

               5.4.   Severability.   In case any right of Holder herein shall
be held to be invalid, illegal or unenforceable, such invalidity, illegality
and/or unenforceability shall not affect any other right granted hereby.




                                      82
<PAGE>   89
               5.5.   Further Assurance.  At any time or from time to time upon
the request of Holder, the Company will execute and deliver such further
documents and do such other acts and things as Holder may reasonably request in
order fully to effectuate the purposes of this Note and to provide for the
payment of the Principal and interest due.

               5.6.   Replacement of Note.   Upon receipt of evidence
reasonably satisfactory to the Company of the ownership of and the loss, theft,
destruction or mutilation of this Note and (in the case of loss, theft or
destruction) upon delivery of an unsecured indemnity agreement reasonably
satisfactory to the Company or (in the case of mutilation) upon surrender and
cancellation of the mutilated Note, the Company will execute and deliver, in
lieu thereof, a new Note of like tenor.

               5.7.   Successors.  All the covenants and agreements contained
in this Note shall bind the parties hereto and their respective heirs,
executors, administrators, distributees, successors and assigns.

               5.8.   Headings.    The section headings in this Note are
inserted for purposes of convenience only and shall have no substantive effect.

               5.9.   Usury Savings.  It is the intent of the Company and the
Holder to contract in strict compliance with all applicable usury laws from
time to time in effect.  In furtherance thereof, the Holder and the Company
hereby stipulate and agree that no term or provision contained in this Note or
any other document or instrument now or hereafter executed in connection
herewith shall ever create (or ever be construed to create) a contract to pay
for the use, forbearance or detention of money interest at a rate in excess of
the maximum nonusurious rate of interest which Holder is permitted to contract
for, charge or receive under applicable law, and as to which the Company could
not successfully assert a claim or defense of usury (the "Highest Lawful
Rate"), and that for purposes hereof "interest" shall include the aggregate of
interest and all charges which constitute interest under applicable law that
are contracted for, reserved, taken, charged or received under or in connection
with this Note.  In the event that the maturity of this Note is accelerated by
reason of any election of the Holder resulting from the occurrence of an Event
of Default or otherwise, or in the event of any prepayment, then such
consideration that constitutes interest may never include more than the maximum
nonusurious amount permitted by applicable law, and excess interest, if any,
provided for in or in connection with this Note shall be cancelled
automatically as of the date of such acceleration or prepayment, and, if
theretofore paid, shall be credited on the principal balance hereof and the
balance thereof, if any, refunded to the Company.  In the event Holder shall
collect, charge contract for or receive moneys which are interest (and/or are
deemed to constitute interest) at a rate in excess of the Highest Lawful Rate,
all such sums in excess of the Highest lawful Rate shall be immediately
credited against the outstanding principal balance of this Note, and the
balance thereof, if any, returned to the Company upon such determination.  All
calculations of the rate of interest contracted for, charged or received under
this Note or under or in connection herewith or otherwise that are made for the
purpose of determining whether such rate exceeds the Highest Lawful Rate shall
be made, to the extent permitted by applicable usury laws, by amortizing,
prorating and spreading in equal parts during the period of the full stated
term of this Note all interest at any time contracted for, charged, collected
or received by Holder in connection herewith.  The provisions of this paragraph
shall control over all provisions of this Note and any other document,
instrument or other agreement now or hereafter executed in connection herewith
which may be in apparent conflict herewith.

<PAGE>   95
                                  SCHEDULE "5"

                                   LITIGATION
        (See definitions of "IRS Audit" and "Market Segment Study Group"
                           and Sections 6.7 and 6.12)

         A.    IRS Audit and Market Study.  The IRS is currently auditing the
Borrower's 401 (k) Plan for the 1993 plan year.  The Borrower believes that,
among other issues, the IRS is examining the relationship between the Borrower
and its worksite employees (including owners of client companies) under the
Code provisions applicable to employee benefit plans.  In addition, the IRS has
established a Market Segment Study Group on Employee Leasing for the stated
purpose of examining whether Professional Employer Organizations ("PEOs"), such
as the Borrower, are the employers of worksite employees under Code provisions
applicable to employee benefit plans and consequently able to offer to worksite
employees benefit plans that qualify for favorable tax treatment.  The Market
Segment Study Group is also examining whether client company owners are
employees of PEOs under Code provisions applicable to employee benefit plans.
The Borrower is unable to predict the timing of the conclusions to be reached
by the IRS in the 1993 audit or of the findings of the Market Segment Study
Group and the ultimate outcome of such conclusions or findings.  If either
process were to conclude that a PEO is not an employer of its worksite
employees for plan purposes, however, such conclusions or findings could have a
material adverse impact on the Borrower's financial condition or results of
operations.  If such a conclusion were reached, worksite employees could not
continue to make contributions to the 401 (k) Plan or pursuant to the cafeteria
plan.  The Borrower believes that, although unfavorable to the Borrower, a
prospective application by the IRS of an adverse conclusion would not have a
material adverse effect on its financial position or results of operations.  If
such conclusion were applied retroactively, employees' vested account balances
would become taxable immediately, the client company would lose its tax
deduction to the extent its matching contributions were not vested, and the
plan trust would become a taxable trust.  In such a scenario, the Borrower
would face the risk of client dissatisfaction as well as potential litigation.
A retroactive application by the IRS of an adverse conclusion could have a
material adverse effect on the Borrower's financial position or results of
operations.  While Administaff believes that a retroactive disqualification is
unlikely, there can be no assurance as to the ultimate resolution of these
issues.

         A definitive judicial interpretation of "employer" in the context of a
PEO or employee leasing arrangement has not been established.  If the Borrower
were found not to be an employer for ERISA purposes, its plans would not comply
with ERISA and the level of services the Borrower could offer may be materially
adversely affected.  Further, as a result of such finding, the Borrower and its
plans would not enjoy the preemption of state laws provided by ERISA and could
be subject to varying state laws and regulations, as well as to claims based
upon state common laws.

         B.    Other Matters.  The matters set forth in Items 1-3, both
inclusive, below (and the attachment referred to in said Item 3) are disclosed
without regard to whether the same are reasonably expected to have a Material
Adverse Effect and are not intended as an agreement by the Borrower that any of
such matters could reasonably be expected to have a Material Adverse Effect if
determined adversely to Borrower.

(1)      TEXAS SALES TAX.  The Texas Tax Code (the "Texas Code") provides that
         certain enumerated services are subject to state sales tax.  There are
         15 of such taxable services, but those which are




                                      89
<PAGE>   96
         performed by an employee for his employer are excluded from taxation.
         Although the Texas Comptroller of Public Accounts (the "Comptroller")
         has consistently taken the position that where worksite employees of a
         PEO were performed taxable services, the PEO is providing taxable
         services and it should collect and remit sales tax for such services,
         the Comptroller has never levied a sales tax on the Borrower.  In
         addition, the Comptroller has conceded that an invoice sent to a
         client company would be taxable only if taxable services constitute
         more than 5% of the total invoice amount, and then only to the extent
         such invoice relates to the enumerated taxable services.

(2)      PROSOFT, INC., V. TECHNOLOGY & BUSINESS CONSULTANTS, INC., &
         ADMINISTAFF, INC.; Cause No. 93-14114; In the 261st Judicial District
         Court of Travis County, Texas.  This lawsuit was filed November 19,
         1993 by a joint venture partner of Technology & Business Consultants,
         Inc., a client company and a company owned by a part owner of
         Administaff, Inc., asserting breach of contract and DTPA actions
         against Technology & Business Consultants, Inc., and Administaff, Inc.
         Administaff, Inc. filed a counterclaim against Plaintiff and a third-
         party action against Grentek, Inc., an alleged third party beneficiary
         of the joint venture contract.  Administaff, Inc.'s position is that
         as it was not a party to the joint venture contract, it had no control
         over any action of Technology & Business Consultants, Inc.  Trial is
         set for October 30, 1995.  Administaff is providing a defense to
         Technology & Business Consultants, Inc., for this claim.  At this
         time, Administaff, Inc. is unable to estimate the amount of its
         potential liability, if any.

(3)      LITIGATION IN THE ORDINARY COURSE OF BUSINESS.  As a professional
         employer, the Borrower is routinely named and threatened to be named,
         along with its client companies, in employment-related actions and
         proceedings.  The Borrower views such litigation as part of its
         ordinary business and maintains insurance for many such potential
         liabilities.  Attachments I, II and III hereto (collectively, the
         "Attachments") describe, respectively, (i) Pending Litigation, (ii)
         Discrimination and Other Employment Related Charges and Complaints and
         (iii) Threatened Litigation.  (Note:  The Borrower is referred to as
         Administaff, Inc. or Administaff in Attachment I.)
