    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE MORE
DETAILED INFORMATION AND THE SUPPLEMENTAL CONSOLIDATED FINANCIAL STATEMENTS,
INCLUDING THE NOTES THERETO, APPEARING ELSEWHERE IN THIS PROSPECTUS. REFERENCES
TO THE COMPANY'S "SALES" IN THIS PROSPECTUS REFER TO THE AGGREGATE SYSTEM-WIDE
SALES OF ALL COMPANY-OWNED, FRANCHISED AND LICENSED OFFICES. SALES DATA OF THE
COMPANY'S FRANCHISED OFFICES USED IN DETERMINING SALES ARE DERIVED FROM REPORTS

                                  THE COMPANY
 
    Interim Services Inc. ("Interim" or the "Company") is a leader in providing
a comprehensive range of customized staffing solutions, including flexible
staffing, home care, full-time placement, consulting and other value-added
services on a national basis to businesses, professional and service
organizations, governmental agencies, health care facilities and individuals. As
of June 28, 1996, the Company operated through a network of 974 offices in the
U.S., Canada and the United Kingdom. Management believes that, based on
system-wide sales, the Company is currently the fourth largest provider of
staffing services in the United States and is the seventh largest provider in
the world.
 
    The Company provides commercial and health care services through two
divisions, each offering numerous specialized skills. The Commercial Services
Division is divided into two units, Commercial Staffing and Professional
Services, which currently represent approximately 50% and 30% of total Company
revenues, respectively. Commercial Staffing fulfills client requirements for
temporary clerical and light industrial skills, in addition to temporary and
permanent workforce management. Professional Services offers consulting and
staffing services in the areas of information technology ("IT"), legal,
accounting, search and human resources. The HealthCare Division provides
physicians, nurses, therapists, home health aides and home companions and
currently represents approximately 20% of total Company revenues.
 
BUSINESS STRATEGY
 
    The Company's goal is to drive revenue and earnings growth by providing the
most innovative human resource solutions worldwide. The Company's strategy
emphasizes broad geographic coverage, a comprehensive range of services and
customized client solutions. Management believes that the Company's proven
earnings performance, brand identity, aggressive growth strategy and
entrepreneurial operating environment are key competitive advantages. The
following details the major elements of the Company's strategy.
 
    INCREASE REVENUE THROUGH OFFICE EXPANSION.  The Company maintains an
aggressive growth strategy which includes establishing Company-owned branches,
adding licensed and franchised offices and making strategic acquisitions. This
diversified growth strategy provides Interim with significant flexibility in
evaluating alternative methods for expansion. Since the initial public offering
of the Company's Common Stock in January 1994 (the "IPO"), Interim has increased
its office base approximately 38% through the addition of 105 greenfield offices
and 71 franchised offices and the acquisition of 90 offices with approximately
$250 million in revenues.
 
    DISPROPORTIONATELY GROW PROFESSIONAL SERVICES.  As part of its acquisition
focus, Interim plans to continue to target disproportionate growth in its
Professional Services businesses, as these offer higher margins than traditional
staffing and provide numerous opportunities to cross-sell other services. The
merger with Brandon Systems Corporation, an IT consulting and staffing company,
is the most recent and significant such acquisition to date. Since the IPO,
approximately $210 million of the $250 million in acquired revenues have been in
Professional Services.
 
                                       3
<PAGE>
    LEVERAGE COMMON BRAND IDENTITY.  Interim is the only national staffing
company which provides commercial, professional and health care services under
the same brand name (e.g., Interim HealthCare, Interim Technology, Interim
Accounting Professionals). This common brand identity facilitates closer client
relationships and cross-selling of services.
 
    PROVIDE INNOVATIVE VALUE-ADDED CLIENT SOLUTIONS.  Interim is committed to
developing innovative human resource solutions to meet the evolving needs of its
clients and providing quality care for its patients. For example, in 1993
Interim pioneered the concept of dedicated, on-site workforce management with
Interim On-Premise ("On-Premise").
 
    DELIVER SERVICES THROUGH SPECIALIZED OFFICES.  Each of the Company's offices
is focused on providing staff with a particular skill set to meet customer
needs. It has been the Company's experience that clients prefer dealing with an
office that "speaks their language" and understands their staffing requirements.
 
    SUPPORT ENTREPRENEURIAL ENVIRONMENT.  All Interim managers are compensated
based on profits generated within their scope of responsibility. Management
believes the Company's decentralized approach provides strong incentives to
manage expenses and increase profits at each office and results in a creative
and committed management team.
 
THE FLEXIBLE STAFFING INDUSTRY
 
    In 1995, STAFFING INDUSTRY REPORT estimated that temporary staffing industry
revenues would be approximately $41 billion and that, from 1991 to 1995, such
revenues would have grown at a compound annual rate of approximately 17.5%.
Demand for staffing services has grown significantly as businesses continue to
increase reliance on temporary personnel in order to manage personnel costs and
meet fluctuating staffing requirements. In addition, many companies use flexible
staffing to reduce administrative overhead by outsourcing operations that are
not part of their core business competencies.
 
    The flexible staffing industry is highly fragmented and is currently
experiencing a trend toward consolidation. The key forces driving consolidation
include the growth of regional or national contracts, expansion of professional
specialties and the need for sophisticated management information systems.
Smaller staffing companies that have limited capital and management resources
are finding it increasingly difficult to compete.

               SUMMARY CONSOLIDATED FINANCIAL AND OPERATING DATA
 
    The Company's 52/53 week fiscal year ends on the last Friday of December.
Fiscal years 1993, 1994 and 1995 ended on December 24, December 30 and December
29, respectively. The Company completed a merger with Brandon Systems
Corporation ("Brandon") on May 23, 1996, whereby 4,401,146 outstanding shares of
Brandon and 235,900 Brandon stock options were exchanged for 3,872,690 shares of
Interim Common Stock and 207,592 Interim stock options (the "Brandon Merger").
This transaction was accounted for as a pooling-of-interests and accordingly,
all historical information has been restated as though the companies had been
combined for all periods prior to the Brandon Merger.
 
    Brandon's fiscal year ended on the Sunday nearest to the end of the month of
September. For restatement purposes, Brandon's historical information has been
converted to a calendar year end to coincide with the Company's fiscal year.

     data for franchised offices are derived from reports provided by
     franchisees, which are not audited.
 
(3)  Prior to September 25, 1993, the Company's working capital and acquisition
     financing were provided by H&R Block, Inc. ("Block"). There was no interest
     charged on intercompany debt. In conjunction with the IPO, effective
     September 25, 1993, Block formalized this arrangement by (i) providing a
     revolving credit facility in the amount of $20,000 to fund the operating
     requirements of the Company; (ii) converting $30,000 of intercompany
     indebtedness on such date to a term loan and (iii) contributing $51,289 to
     the capital of the Company. The earnings data for fiscal 1991, 1992 and
     1993 give effect to this arrangement as if it occurred at the beginning of
     the periods. Interest expense has been computed at 6% and income taxes at

                                  RISK FACTORS
 
    IN ADDITION TO THE OTHER INFORMATION IN THIS PROSPECTUS, THE FOLLOWING RISK
FACTORS SHOULD BE CONSIDERED CAREFULLY IN EVALUATING AN INVESTMENT IN SHARES OF
THE COMMON STOCK OFFERED HEREBY.
 
COMPETITIVE MARKET
 
    The flexible staffing industry is highly competitive with limited barriers
to entry. The Company competes in national, regional and local markets with full
service agencies and with specialized staffing service agencies and home care
providers. The majority of competitors are significantly smaller than the
Company. However, several competitors have greater marketing and financial
resources than those of the Company. The Company expects the level of
competition to remain high in the future. See "Description of Operations --
Competition".
 
ABILITY TO GROW AND MANAGE GROWTH
 
    The Company has experienced significant growth in the past through the
acquisition of existing businesses and the opening of new offices, as well as
through licensing and franchising. The ability of the Company to continue to
grow and to manage its growth will depend on a number of factors, including
existing and emerging competition for acquisitions, the availability of capital,
and the Company's ability to successfully recruit and train staff. There can be
no assurance that the Company will continue to be able to establish and expand
its market presence or successfully identify suitable acquisition candidates
and/or complete the acquisitions on terms favorable to the Company. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business -- Business Strategy".
 
RELIANCE ON KEY PERSONNEL
 
    The Company is highly dependent on its management. The continued success of
the Company will depend in large part on the abilities and continued services of
Raymond Marcy, its President and Chief Executive Officer, and certain other
officers and key employees. The loss of Mr. Marcy or other officers and key
employees could have a material adverse effect on the Company's operations.
 
INFORMATION TECHNOLOGY TRENDS
 
    Growth in the use of flexible staffing in the IT area in recent years has
been driven largely by rapid technological advances. As the sophistication and
complexity of business information systems increase, and as the general
corporate trend toward downsizing continues, businesses are increasingly turning
to specialized, outside technical personnel to support their IT operations. The
Company's success in the IT area depends in large part on its ability to keep
pace with existing technology, predict new technological advancements and
recruit and train based on these trends. See "Description of Operations --
Commercial Services Division".
 
HEALTH CARE COMPETITION
 
    The Company faces increasing competition in health care staffing from
providers such as hospitals, other primary care institutions and stand-alone
home care agencies. As it becomes evident that home care is an efficient
substitute to hospital care, hospitals are experiencing pressure to integrate
the home care services that their doctors may otherwise refer to outsiders.
Today more than half of U.S. hospitals offer home care, according to the
American Hospital Association ("AHA"). Although federal law imposes significant
restrictions on the ability of physicians employed by a hospital to refer
patients to a home health agency owned by or affiliated with the hospital, the
AHA is lobbying for a moratorium on the law and the Health Care Financing
Administration has been slow to undertake enforcement activities. The growth of
hospital-owned home care agencies and the potential for self-referral business
could hinder the growth of the HealthCare Division.
 
DEPENDENCE ON AVAILABILITY OF QUALIFIED PERSONNEL
 
    The Company depends upon its ability to attract qualified personnel who
possess the skills and experience necessary to meet the staffing requirements of
its clients. The Company must continually
 
                                       7
<PAGE>
evaluate and upgrade its base of available qualified personnel to keep pace with
changing client needs and emerging technologies. Competition for individuals
with proven professional skills is intense. See "Description of Operations --
Commercial Services Division" and "-- HealthCare Division".
 
EFFECT OF FLUCTUATIONS IN THE GENERAL ECONOMY
 
    Demand for traditional flexible staffing is significantly affected by the
general level of economic activity. When economic activity increases, flexible
staff are often added before full-time employees are hired. In addition, in the
early stages of a recovery, before employment returns to previous levels, it is
easier to hire employees for placement on a temporary basis. However, as
economic activity slows, many companies reduce their usage of flexible staff
before undertaking layoffs of their regular employees. While traditionally the
demand for the health care services of the Company has not been directly
affected by the overall state of the economy, the Company's HealthCare Division
may in the future be affected by decreases in economic activity. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Seasonality and Cyclicality of Business".
 
EMPLOYER RISKS
 
    Flexible staffing providers employ and place people in the workplace of
other businesses. Attendant risks of such activity which could increase the
Company's cost of doing business include possible claims of discrimination and
harassment, employment of illegal aliens, errors and omissions by the Company's
flexible staff, particularly for the acts of temporary professionals (e.g.,
accountants and attorneys), misuse or misappropriation of client funds or
proprietary information, and other similar claims. While the Company maintains
insurance coverage for general liability, errors and omissions and employee
theft, such insurance coverage may not be adequate in scope or amount to cover
any such liability.
 
GOVERNMENTAL REGULATION
 
    A number of states have adopted laws regulating companies that provide
health care services which could adversely affect the Company's profit margins.
In many of the states with such laws, the Company need only be licensed.
However, in 21 states and the District of Columbia, home care providers must
receive a certificate of need ("CON") from the state. CON laws restrict the
types of care that may be provided and can limit or prohibit a company's ability
to provide certain services and to establish or expand its operations within
such state. CON requirements and restrictions vary substantially from state to
state. See "Description of Operations -- Governmental Regulations".
 
FRANCHISING RISKS
 
    Approximately 40% of system-wide sales, representing approximately 2.4% of
Company revenues, were derived from franchised operations in the first half of
1996. Moreover, the largest 10 franchisees (based on sales volume) accounted for
16% of system-wide sales in the first half of 1996. Franchisees may leave the
franchise system at the end of the term of their franchise agreements and have
occasionally terminated their franchise agreements before the end of the
agreement term. While the Company's agreements contain non-competition
covenants, such covenants may not be enforceable nor prevent the loss of sales.
See "Description of Operations -- Office Structure".
 
INSURANCE
 
    The Company is required to pay unemployment insurance premiums and workers'
compensation costs for its flexible staff. Unemployment insurance premiums paid
by employers have continued to increase as a result of increased levels of
unemployment and the extension of periods of time for which benefits are
available. Workers' compensation costs have continued to increase as states have
raised benefit levels and liberalized allowable claims. In addition, the
Company's cost of providing health benefits could increase as the result of
future health care reforms. Specifically, certain federal and state legislative
proposals have included provisions requiring employers to extend health
insurance benefits to flexible staff who do not presently receive such benefits.
Future results of operations could be adversely affected if the Company is not
able to increase the fees charged to its clients to absorb the
 
                                       8
<PAGE>
increased costs related to unemployment insurance, workers' compensation, or
employer-paid health insurance benefits that must be extended to flexible staff.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations".
 
STOCK PRICE VOLATILITY
 
    The price of the Company's Common Stock has increased significantly since
its IPO in January 1994. The market price of the Common Stock could be subject
to significant fluctuations in response to operating results of the Company,
changes in general conditions in the economy, the financial markets, the
staffing industry or other developments affecting the Company, its competitors,
or clients which may be unrelated to the Company's performance. See "Price Range
of Common Stock".
 
ANTI-TAKEOVER CONSIDERATIONS
 
    The Company's Restated Certificate of Incorporation and the Delaware General
Corporation Law contain certain provisions that are intended to make it more
difficult for a party to acquire, and/or to discourage a party from attempting
to acquire, control of the Company without approval of the Company's Board of
Directors. In addition, the Company's Board of Directors has adopted a
stockholder rights plan. The foregoing may discourage unsolicited tender offers
or other bids for the Company's Common Stock at a premium over the prevailing
market price. In addition, the requirement that a change of control of the
Company be approved by the Public Health Council of the New York State
Department of Public Health may have a similar effect. See "Description of
Operations -- Governmental Regulation".

                                  THE COMPANY
 
    The Company was founded in 1946 to provide temporary industrial staffing
services. Nursing and home care services were added in 1966. On August 16, 1978,
the Company, then known as Personnel Pool of America, Inc., was acquired by H&R
Block, Inc. ("Block"). On January 22, 1991, Block acquired another temporary
service business, Interim Systems Corporation ("ISC"). At the time of the
acquisition, ISC was providing clerical, light industrial and health care
personnel through 178 branch offices in 20 states and three Canadian provinces.
The businesses of the Company and ISC were combined on December 31, 1991. On
June 15, 1992, the Company changed its name to "Interim Services Inc.".
 
    On January 27, 1994, Block completed the sale at $20 per share of 10 million
shares of Interim, its entire holding. Since its IPO, the Company has acquired
12 flexible staffing companies including five in 1994, five in 1995 and two
companies thus far in 1996.
 
    The Company is a Delaware corporation whose corporate headquarters are
located at 2050 Spectrum Boulevard, Fort Lauderdale, Florida 33309. The
Company's telephone number is (954) 938-7600.
 
                                USE OF PROCEEDS
 
   
    The net proceeds to the Company from the Offering are estimated to be
approximately $165.5 million (approximately $192.2 million if the U.S. and
International Underwriters' over-allotment option is exercised in full) (at an
assumed initial public offering price of $43 7/8 and after deducting the
estimated underwriting discount and offering expenses). Approximately $120.0
million of such proceeds will be used to repay principal and interest under the
Company's Credit Facilities (as defined below) with the remainder to be used for
general corporate purposes including future acquisitions. To the extent the
Underwriters' over-allotment option is exercised, net proceeds from such
exercise will also be used for general corporate purposes including future
acquisitions. The Company will not receive any proceeds from the sale of shares
by the Selling Stockholders.
    
 
    The Company maintains a $150.0 million committed senior revolving credit
agreement and has also established short-term, unsecured, uncommitted lines of
credit with certain banks (collectively, the "Credit Facilities"). The Company
utilizes the Credit Facilities to fund acquisitions, to supply working capital
and to provide for general corporate needs. As of June 28, 1996, the total
outstanding debt under all of the Company's Credit Facilities was $120.0 million
with an effective interest rate of 5.98%. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations Description of Company
Financing".

Stockholders of record.
    
 
                                DIVIDEND POLICY
 
    No cash dividend or other cash distribution with respect to the Company's
Common Stock has ever been paid by the Company, although Brandon paid cash
dividends prior to the Brandon Merger. The Company currently intends to retain
any earnings for use in its business and does not anticipate paying any cash
dividends in the foreseeable future.

(4) Prior to September 25, 1993, the Company's working capital and acquisition
    financing were provided by Block. There was no interest charged on
    intercompany debt. In conjunction with the IPO, effective September 25,
    1993, Block formalized this arrangement by (i) providing a revolving credit
    facility in the amount of $20,000 to fund the operating requirements of the
    Company; (ii) converting $30,000 of intercompany indebtedness on such date
    to a term loan and (iii) contributing $51,289 to the capital of the Company.
    The earnings data for fiscal 1991, 1992, and 1993 give effect to this
    arrangement as if it occurred at the beginning of the periods. Interest
    expense has been computed at 6% and income taxes at the statutory rate.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    THE FOLLOWING DISCUSSION AND ANALYSIS SHOULD BE READ IN CONJUNCTION WITH THE
"SELECTED CONSOLIDATED FINANCIAL AND OPERATING DATA" AND NOTES THERETO INCLUDED
ELSEWHERE IN THIS PROSPECTUS AND THE CONSOLIDATED FINANCIAL STATEMENTS AND
RELATED NOTES INCLUDED ELSEWHERE IN THIS PROSPECTUS.
 
INTRODUCTION
 
    The Company operates within one industry segment, providing flexible
staffing in the United States, Canada and parts of the United Kingdom. The
Company's business is organized into two divisions, Commercial Services and
HealthCare.
 
    The Company completed a merger with Brandon, a strategic IT staffing
company, on May 23, 1996, which was accounted for under the pooling-of-interests
method of accounting. Accordingly, the historical information has been restated
for all periods prior to the Brandon Merger. All other acquisitions to date have
been accounted for under the purchase method of accounting.
 
    During the nine months ended December 30, 1994, the Company changed its
fiscal year from a 52 or 53-week year ending on the last Friday in March to a 52
or 53-week year ending on the last Friday in December. The change in fiscal year
was made to align the Company's year end more closely with the standard for
companies in the flexible staffing industry. The financial statements have been
restated, for all years presented, to a 52 or 53-week year ending on the last
Friday in December.
 
GENERAL INDUSTRY TRENDS
 
    Demand for staffing services has grown significantly as businesses continue
to increase reliance on temporary personnel to manage operating costs and meet
fluctuating staffing requirements. In addition, many companies use flexible
staffing to reduce administrative overhead by outsourcing operations that are
not part of their core business competencies. Furthermore, the flexible staffing
industry is highly fragmented and is currently experiencing a trend toward
consolidation, which is contributing to above-market rates of growth for a
number of companies in the industry.
 
SALES OVERVIEW
 
    System-wide sales data includes sales from all Company-owned, franchised and
licensed offices. Sales data for franchised offices are derived from reports
provided by franchisees, which are not audited. During 1995, Company sales
increased by 16.8% to $1,494.3 million. From fiscal 1993 to 1995, system-wide
sales increased by 37.6%. Sales growth from 1993 through 1995 is due primarily
to the rapidly growing markets in which the Company operates, new branch
openings, growth in licensing and most recently, growth in Professional Services
through the acquisition of IT, legal and accounting branch offices.
 
    Franchisee sales have decreased as a percentage of total sales due to a
slower rate of growth among franchisees and the repurchase of franchises by the
Company. Licensee sales in the six months ended June 28, 1996 decreased as a
percentage of total sales as a result of the conversion of a large license to a
franchise.
 
    The following table summarizes the Company's sales mix for the last three
fiscal years and the six months ended June 30, 1995 and June 28, 1996:

REVENUE OVERVIEW
 
    From 1993 through 1995 Commercial Services Division revenue increased as a
percentage of total Company revenue principally due to the accelerated growth
rate and acquisition activity in Professional Services. For the six months ended
June 28, 1996, Professional Services revenues increased over the prior year
period primarily as a result of acquisitions.

RESULTS FROM OPERATIONS OVERVIEW
 
    During the past three years, the Company's gross profit margin remained
relatively stable as higher gross margins in Professional Services were
partially offset by (i) the growth of Commercial Staffing revenues, which have
lower gross profit margins, and (ii) the decline of franchise royalties (which
essentially contribute 100% to gross profit) as a percent of total Company
revenue.
 
    The following table sets forth operational results as a percentage of total
revenues for the periods indicated.

    to industry norms. The effect of this reclassification is to increase gross
    profit by 0.4% in 1995.
 
SIX MONTHS ENDED JUNE 28, 1996 COMPARED TO SIX MONTHS ENDED JUNE 30, 1995
 
    REVENUES
 
    For the six months ended June 28, 1996, revenues increased 37.5% to $545.9
million from $397.1 million in the prior year period. Commercial Staffing
revenues increased 18.3% reflecting the expansion of the On-Premise program and
an increase in the number of offices and services provided. Professional
Services revenues increased 157.0% reflecting significant acquisition activity
and internal growth, primarily in IT. HealthCare Division revenues increased
14.3% due to increases in number of offices and expansion of Occupational Health
and Physicians services.

<PAGE>
    GROSS PROFIT
 
    Gross profit increased 35.8% to $165.7 million from $122.0 million in the
prior year period. Increases in gross profit and cost of services are associated
with the increase in revenues. Gross profit margin decreased to 30.3% from 30.7%
in the prior year principally due to a decline in franchise royalties as a
percent of total Company revenue. Franchise royalties essentially contribute
100% to gross profit.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
 
    Selling, general and administrative expenses increased 41.6% to $116.7
million from $82.5 million in the prior year period. Selling, general and
administrative expenses as a percentage of revenues were 21.4% compared to 20.8%
a year ago due to the higher relative costs associated with Professional
Services.
 
    LICENSEE COMMISSIONS
 
    Licensee commissions increased 2.8% to $18.7 million from $18.2 million in
the prior year period. Licensee commissions as a percent of revenues decreased
from 4.6% to 3.4% due to acquisition activity.
 
    AMORTIZATION OF INTANGIBLES
 
    Amortization expense increased 31.8% to $4.3 million from $3.3 million in
the prior year period reflecting the increase in intangible assets arising from
acquisitions.
 
    TAXES ON EARNINGS
 
    The effective tax rate of 63.0% for the first six months of 1996 results
from a large portion of merger costs being non-deductible. The effective tax
rate, excluding the effects of non-recurring merger charges, was 43.6% compared
to 43.8% in the prior year period. The decline in the effective tax rate is due
primarily to the fact that during these periods amortization of certain
non-deductible intangibles remained relatively fixed while earnings before taxes
increased. Management anticipates that the Company's effective income tax rate
will continue to decrease slightly as non-deductible amortization decreases as a
percentage of earnings before taxes.
 
    NET EARNINGS
 
    Net earnings for the six months excluding merger costs (net of taxes)
increased 25.0% to $12.7 million, or $0.80 per share, from $10.2 million, or
$0.65 per share in the prior year period. This represents a 23.1% increase in
per share earnings. Including merger costs, net earnings decreased 49.4% to $5.1
million, or $0.32 per share from $10.2 million or $0.65 per share in the prior
year period. The weighted average number of shares outstanding was 15,916,000
compared to 15,659,000 in the prior year period.
 
FISCAL 1995 COMPARED TO 1994
 
    REVENUES
 
    Revenues in 1995 increased 22.6% (24.3% excluding the 53rd week in 1994) to
$864.2 million from $704.7 million in 1994. Commercial Staffing revenues
increased 19.5% (21.1% excluding the 53rd week in 1994) due to an increase in
the number of billed hours, offices acquired and continued internal office
expansion. Professional Services revenues increased 38.2% (38.9% excluding the
53rd week in 1994) primarily related to acquisitions that occurred in 1995.
HealthCare Division revenues increased 24.2% (26.8% excluding the 53rd week in
1994) due to continued expansion in home care.
 
    GROSS PROFIT
 
    Gross profit in 1995 increased 23.8% to $264.1 million from $213.3 million
in 1994 (22.4% excluding reclassifications adopted in 1995 in which certain
non-payroll related costs were removed from cost of services to conform to
industry norms). The gross profit margin was 30.6% (30.2% excluding
reclassifications) as compared with 30.3% in the prior year.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
 
    Selling, general and administrative expenses increased 28.5% to $177.1
million from $137.9 million in 1994. Selling, general and administrative
expenses as a percentage of total revenue increased to 20.5% in 1995 from 19.6%
in 1994 as a result of a full year of HealthCare Division acquisitions made in
 
                                       17
<PAGE>
1994 and a partial year of Professional Services acquisitions made in 1995.
Professional Services such as executive search, human resources, accounting and
therapy have a higher gross profit margin but require higher selling, general
and administrative expenditures as a percentage of revenue.
 
    LICENSEE COMMISSIONS
 
    In 1995, licensee commissions increased 10.4% to $37.3 million from $33.8
million in 1994 as a result of an increased number of licensees.
 
    AMORTIZATION OF INTANGIBLES
 
    For 1995, amortization expense increased 14.0% to $6.9 million from $6.0
million in the prior year period reflecting the increase in intangible assets
arising from acquisitions.
 
    TAXES ON EARNINGS
 
    The provision for income taxes for 1995 reflects an effective tax rate of
43.2%, which is less than the 45.2% rate for 1994. The lower effective tax rate
for 1995 is the result of (i) a decrease in the effective rate relating to state
income taxes and (ii) non-deductible amortization of intangible assets remaining
fixed while earnings before income taxes increased.
 
    NET EARNINGS
 
    In 1995, net earnings increased 22.0% to $23.7 million from $19.5 million in
1994. Net earnings per share increased 20.6% to $1.52 in 1995 from $1.26 in
1994. The weighted average shares outstanding was 15,662,000 in 1995 compared to
15,391,000 in 1994.
 
FISCAL 1994 COMPARED TO 1993
 
    REVENUES
 
    Revenues in 1994 increased 22.7% (21.1% excluding the 53rd week in 1994) to
$704.7 million from $574.3 million in 1993. Commercial Staffing revenues
increased 24.2% (22.6% excluding the 53rd week in 1994) due to an increase in
the number of billed hours, the continued economic recovery and increases in the
number of licensed offices. Professional Services revenues increased 25.4%
(24.9% excluding the 53rd week in 1994) due to acquisitions. HealthCare Division
revenues increased 15.6% (13.3% excluding the 53rd week in 1994) due to growth
in the home care market and the addition of more offices.
 
    GROSS PROFIT
 
    Gross profit for 1994 increased 23.8% to $213.3 million from $172.2 million
in 1993. The gross profit margin increased to 30.3% in 1994 from 30.0% in 1993,
primarily as a result of increased HealthCare revenues which typically have
higher gross profit margins than Commercial Staffing. Franchise royalties
increased from the comparable prior year period due to increases in hourly
rates.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
 
    Selling, general and administrative expenses increased 15.1% to $137.9
million from $119.8 million in 1993. Selling, general and administrative
expenses as a percentage of total revenue decreased to 19.6% in 1994 from 20.9%
in 1993 as a result of a decrease in bad debt expenses and acquisitions of
customer lists increasing revenues without commensurate increases in selling,
general and administrative expenses.
 
    LICENSEE COMMISSIONS
 
    In 1994, licensee commissions increased 64.2% to $33.8 million from $20.6
million in 1993 as a result of an increased number of licensees.
 
    AMORTIZATION OF INTANGIBLES
 
    Amortization expense increased 6.5% to $6.0 million from $5.7 million in the
prior year period reflecting the increase in intangible assets arising from
acquisitions.
 
                                       18
<PAGE>
    TAXES ON EARNINGS
 
    The provision for income taxes for 1994 reflects an effective tax rate of
45.2%, which is less than the 47.4% rate for 1993 (adjusted to reflect the Block
financing arrangement as if it occurred at the beginning of the period). The
decline in the effective tax rate is due primarily to the fact that, during
these periods, amortization of certain non-deductible intangibles has remained
relatively fixed while earnings before taxes increased.
 
    NET EARNINGS
 
    Net earnings increased 51.4% to $19.5 million in 1994 from $12.9 million in
1993. Net earnings per share increased 35.5% to $1.26 in 1994 from $0.93 in
1993. The weighted average number of shares outstanding was 15,391,000 in 1994
compared to 13,873,000 in 1993.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    Historically, the Company has financed its operations through cash generated
by operating activities and bank lines of credit. The Company's principal uses
of cash are funding acquisitions, capital expenditures, working capital needs
and repayment of debt. The nature of the Company's business requires payment of
wages to its flexible staff on a weekly, or bi-weekly basis, while payments from
clients are generally received 30-60 days after billing for Commercial Staffing
and Professional Services and 50 or more days for HealthCare clients. The
Company believes that its internally generated funds and lines of credit are
sufficient to support anticipated levels of growth of the Company.
 
    Net cash flow from operating activities was $14.3 million, $10.1 million and
$6.6 million in years 1993, 1994 and 1995, respectively, and $7.4 million and
($5.8) million for the first six months of 1995 and 1996, respectively. The
decrease in cash flow from operating activities was due to increased funding of
accounts receivable resulting from strong revenue growth during the year and an
increase in loans outstanding to franchisees that are included in other assets.
Accounts receivable increased to $143.2 million at the end of 1995 from $101.7
million at the end of 1994 as a result of an increase in revenues (with
comparable days outstanding) over the previous year and a higher level of health
care receivables as compared to the prior year. Additionally, merger costs paid
in the six months ended June 28, 1996 contributed to net cash being used in
operating activities.
 
    The Company's capital expenditures (excluding acquisitions) during 1993,
1994 and 1995 were funded through internally generated funds. The Company
anticipates increased expenditures to continue development and implementation of
its information technologies. Additionally, the Company has committed
approximately $7.6 million to build and furnish an addition to its corporate
headquarters. As of June 28, 1996, approximately $3.2 million of this amount had
been spent.
 
    Historically, Brandon invested its cash in excess of immediately foreseeable
requirements principally in interest-bearing marketable securities. As a result
of the Brandon Merger, these investments were liquidated to pay down debt.
 
DESCRIPTION OF COMPANY FINANCING
 
    On April 6, 1994, the Company replaced a $30 million term loan and a $20
million revolving credit facility with Block with a new $50 million committed
senior revolving credit agreement. In November 1995, this facility was increased
to $150 million. The credit facility is available to fund the Company's
acquisitions, to supply working capital and to provide for general corporate
needs. Interest charged on the facility is based, at the Company's option, on
either the banks' base rate or LIBOR plus an applicable margin. The margin
changes based on the Company's leverage and fixed charge ratios. The facility,
which terminates April 6, 1999, contains customary covenants, including the
maintenance of certain financial ratios such as minimum net worth and
restrictions on the incurrence of liens and additional indebtedness.
 
    In addition, the Company has established short term, unsecured, uncommitted
lines of credit with certain banks. These lines of credit are based on LIBOR and
are available to fund the Company's short term capital requirements. As of June
28, 1996, the total outstanding debt under all of the Company's
 
                                       19
<PAGE>
credit agreements was $120.0 million with an effective interest rate of 5.98%
Approximately $100.0 million of the Company's total outstanding debt was
incurred in connection with acquisitions made by the Company.
 
INFLATION
 
    The effects of inflation on the Company's operations were not significant
during the periods presented in the financial statements.
 
SEASONALITY AND CYCLICALITY OF BUSINESS
 
    The Company's businesses are not seasonal in nature. The Company's
commercial business has historically been considered to be cyclical, often
acting as a coincidental indicator of both economic downswings and upswings.
However, as a result of general shifting of employment patterns and the growth
in On-Premise, management believes that the Company's commercial business is
becoming less cyclical. In addition, the Company's health care business is not
cyclical and tends to dampen any cyclical effects from the commercial sector. No
single customer accounts for more than 1% of the Company's revenues.
 
OTHER MATTERS
 
    In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Accounting Standards ("SFAS") No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of".
SFAS No. 121 establishes accounting standards for the impairment of long-lived
assets, certain identifiable intangibles, and goodwill related to those assets
to be held and used and for long-lived assets and certain identifiable
intangibles to be disposed of. SFAS No. 121 will apply to the Company for the
year ended December 27, 1996. The adoption of this statement has not had a
material impact on the Company's financial position or results of operations.
 
    In October 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based
Compensation", which is effective for the Company beginning January 1, 1996.
SFAS No. 123 requires expanded disclosures of stock-based compensation
arrangements with employees and encourages (but does not require) compensation
cost to be measured based on the fair value of the equity instrument awarded.
Companies are permitted, however, to continue to apply APB Opinion No. 25 to its
stock-based compensation awards to employees and Interim will disclose the
required pro forma effect on net income and earnings per share in its 1996 Form
10-K and Annual Report.

                                    BUSINESS
 
COMPANY OVERVIEW
 
    The Company is a leader in providing a comprehensive range of customized
staffing solutions, including flexible staffing, home care, full-time placement,
consulting and other value-added services on a national basis to businesses,
professional and service organizations, governmental agencies, health care
facilities and individuals. As of June 28, 1996, the Company operated through a
network of 974 offices in the U.S., Canada and the United Kingdom. Management
believes that, based on system-wide sales, the Company is currently the fourth
largest provider of staffing services in the United States and is the seventh
largest provider in the world.
 
    The Company provides commercial and health care services through two
divisions, each offering numerous specialized skills. The Commercial Services
Division is divided into two units, Commercial Staffing and Professional
Services, which currently represent approximately 50% and 30% of total Company
revenues, respectively. Commercial Staffing fulfills client requirements for
temporary clerical and light industrial skills, in addition to temporary and
permanent workforce management. Professional Services offers consulting and
staffing services in the areas of IT, legal, accounting, search and human
resources. The HealthCare Division provides physicians, nurses, therapists, home
health aides and home companions and currently represents approximately 20% of
total Company revenues.
 
THE FLEXIBLE STAFFING INDUSTRY
 
    Demand for staffing services has grown significantly as businesses continue
to increase reliance on temporary personnel to manage operating costs and meet
fluctuating staffing requirements. In addition, many companies use flexible
staffing to reduce administrative overhead by outsourcing operations that are
not part of their core business competencies. Furthermore, the flexible staffing
industry is highly fragmented and is currently experiencing a trend toward
consolidation. The key forces driving consolidation include the growth of
regional or national contracts, expansion of professional specialties and the
need for sophisticated management information systems. Smaller staffing
companies that have limited capital and management resources are increasingly
finding it difficult to compete.
 
    TRADITIONAL FLEXIBLE STAFFING MARKET
 
    In 1995, STAFFING INDUSTRY REPORT estimated that temporary staffing industry
revenues would be approximately $41 billion and that, from 1991 to 1995, such
revenues would have grown at a compound annual rate of approximately 17.5%. The
Bureau of Labor Statistics forecasts that the flexible staffing industry will be
the seventh fastest growing employment category in the United States, increasing
over four times faster than the general labor force from 1994 to 2005.
 
    PROFESSIONAL AND IT STAFFING MARKETS
 
    Certain categories of professional staffing services are experiencing
considerable growth, in excess of the industry as a whole, as companies realize
they can enjoy the same type of flexibility for personnel such as computer
programmers, accountants, paralegals and attorneys as they do with traditional
flexible staff. Furthermore, the use of technology has led to a dramatic rise in
demand for technical project support, software development and other
computer-related services. Corporations are outsourcing many of these
departments and/or utilizing flexible staffing to attempt to keep pace with
rapidly changing technology and increasing demand for these types of technical
skills.
 
    Revenues from professional/specialty temporary staffing were estimated to
grow from $2.4 billion in 1993 to $4.0 billion in 1995, which would represent a
compound annual growth rate of approximately 30% according to STAFFING INDUSTRY
REPORT. In addition, revenues from technical/computer temporary staffing were
estimated to grow from $5.7 billion in 1993 to $8.9 billion in 1995, which would
represent a compound annual growth rate of approximately 25%.
 
HEALTH CARE STAFFING INDUSTRY
 
    Health care staffing services include providing general and specialized
health care skills and companionship in the home environment, as well as
providing the same health care skills in hospitals,
 
                                       21
<PAGE>
nursing homes, HMOs and other health care facilities. Home care is one of the
fastest growing sectors of the health care industry and has grown at an
estimated average annual rate of 16% since 1988 according to the Bureau of Labor
Statistics.
 
    Contributing to the growth of home care is national pressure to reduce
health care costs. Studies indicate that the cost of home care averages 40% to
70% of that of institutional care. In addition, industry growth is driven by the
increase in overall demand for health care for the aging American population and
by technological advances which have made it possible to perform many
sophisticated medical procedures in the home.
 
BUSINESS STRATEGY
 
    The Company's goal is to drive revenue and earnings growth by providing the
most innovative human resource solutions worldwide. The Company's strategy
emphasizes broad geographic coverage, a comprehensive range of services and
customized client solutions. Management believes that the Company's proven
earnings performance, brand identity, aggressive growth strategy and
entrepreneurial operating environment are key competitive advantages. The
following details the major elements of the Company's strategy.
 
    INCREASE REVENUE THROUGH OFFICE EXPANSION
 
    The Company maintains an aggressive growth strategy which includes
establishing Company-owned branches, adding licensed and franchised offices and
making strategic acquisitions. Growth through acquisition is generally preferred
when building experience in a particular professional service area or when an
acquisition in traditional commercial staffing or home care business will enable
Interim to fill-in or expand into an important geographic market. The Company's
successful diversified growth strategy provides Interim with significant
flexibility in evaluating alternative methods for expansion.
 
    Since the IPO, the Company has increased its office base by approximately
38% to 974, adding approximately $250 million in revenues from 12 acquired
flexible staffing companies. The following table provides detail of the
Company's acquisitions since the IPO.

    In addition to external acquisitions, Interim usually purchases franchises
and licenses which are for sale. The Company is generally the purchaser of
choice when an Interim franchisee or licensee decides to sell its business. The
Company has a first right of refusal on any franchise sale at the same terms and
conditions as may be agreed with another purchaser and has a standard purchase
option on licenses. Overall, Company-owned branches yield higher profits than
franchised or licensed offices and therefore the purchase of these offices is
accretive to overall earnings.
 
                                       22
<PAGE>
    DISPROPORTIONATELY GROW PROFESSIONAL SERVICES
 
    As part of its acquisition focus, Interim plans to continue to target
disproportionate growth in its Professional Services businesses. Demand
continues to expand for professional staffing services, reflecting changing
attitudes toward workforce management and the proliferation of technical skills
required in an office environment. The Company believes that such services tend
to provide higher margins and to be less cyclical than traditional flexible
staffing and to provide attractive opportunities to cross-sell other Interim
services. Since the IPO, approximately $210 million of the $250 million in
acquired revenues have been in Professional Services.
 
    LEVERAGE COMMON BRAND IDENTITY
 
    Interim is the only national staffing company which provides commercial,
professional and health care services under the same brand name (e.g., Interim
HealthCare, Interim Technology, Interim Accounting Professionals). Such brand
identity facilitates cross-selling as management has found that customers
appreciate the ability to do business with a familiar company while also having
access to a broad range of specialists. The common Company identity also
facilitates information flow and smooth interaction among the various Interim
offices. In addition, through its common brand identity the Company and its
franchisees are better able to benefit from national media advertising.
Accordingly, all acquisitions are converted to the Interim name as soon as
practicable. The increasing demand by large companies for centralized staffing
services is increasing the importance of being able to offer a high-profile,
wide range of services over a broad geographic area. Interim is well-positioned
to capitalize on this trend.
 
    PROVIDE INNOVATIVE VALUE-ADDED CLIENT SOLUTIONS
 
    Interim is committed to developing innovative human resource solutions to
meet the evolving needs of its clients and providing quality care for its
patients. For example, in 1993 Interim pioneered the concept of dedicated,
on-site workforce management with Interim On-Premise. Interim On-Premise
accounted for 18% of the Commercial Services Division's revenue for the six
months ended June 28, 1996. Executive search, placement and human resource
consulting services have similarly been added in response to client needs.
Recognizing the changing needs of the health care marketplace and anticipating
the demands of health care payors, Interim developed InterPath, a proprietary
medical record documentation and outcome measurement system for home care
services.
 
    DELIVER SERVICES THROUGH SPECIALIZED OFFICES
 
    Each of the Company's offices is focused on providing staff with a
particular skill set to meet customer needs. The managers and sales people in
these offices have training and experience in the relevant field and are able to
establish relationships with those individuals making the buying decisions for
that service at a client organization. For example, the IT offices market their
services directly to the information resources department head, the accounting
offices market to the controller and the HealthCare offices market to the care
manager. It has been the Company's experience that clients prefer dealing with
an office that "speaks their language" and understands their staffing
requirements.
 
    SUPPORT ENTREPRENEURIAL ENVIRONMENT
 
    The Company seeks highly talented managers who are capable of operating
independently and who will succeed within the Company's decentralized structure.
All Interim managers are compensated based on profits generated within their
scope of responsibility. Branch, area and regional managers are responsible for
their own hiring, pricing, business mix and local promotion. The Company's use
of franchising and licensing contributes to this entrepreneurial environment.
Management believes the Company's decentralized approach provides strong
incentives to manage expenses and increase profits at each office and results in
a creative and committed management team. In addition, the Company has granted
stock-based compensation in the form of options, representing 8% of the
Company's outstanding Common Stock on a fully-diluted basis.

                           DESCRIPTION OF OPERATIONS
 
COMMERCIAL SERVICES DIVISION
 
    The Commercial Services Division provides skills in two primary areas,
traditional commercial flexible staffing and professional services. Each area
offers a comprehensive range of skills to fulfill client requirements and are
described below.
 
    Commercial Staffing offers personnel with traditional temporary clerical and
light industrial skills on a flexible basis. In addition to traditional flexible
staffing, Interim provides value-added staffing services to large clients
through its On-Premise product. Approximately 50% of the Company's total
revenues are currently derived from Commercial Staffing.
 
    Professional Services offers a comprehensive range of consulting and
staffing services in the areas of IT, legal, accounting, search and human
resources. The Company provides personnel with skills in specialized
professional areas, including software analysts, computer programmers, network
administrators, attorneys, paralegals, court reporters, accountants and human
resource managers. In addition, the Company offers full-time placement,
recruiting, consulting and executive retained search services. Approximately 30%
of the Company's current total revenues are derived from Professional Services.
 
    COMMERCIAL STAFFING
 
    The traditional flexible staffing business entails providing a wide variety
of clerical, administrative, assembly and light industrial skills. In addition
to supplying personnel to perform general office tasks such as reception,
copying and filing, the Company provides personnel who are proficient in word
processing, graphics, spreadsheets or database management. In the light
industrial area, Interim supplies personnel to perform light industrial tasks
such as electronic and precision assembly, PC board assembly, packaging,
shipping and receiving, warehousing, landscaping, construction and equipment
operation. The Company also offers full-time placement of these skills.
 
    INTERIM ON-PREMISE
 
    Four years ago, the Company introduced a new staffing concept, Interim
On-Premise, whereby a client delegates management of its flexible staffing needs
to the Company, allowing the client to focus on its core business activities.
On-Premise has evolved to include managing a client's entire workforce on-site,
a significant portion of which is permanent staff. To better serve its
On-Premise clients, the Company has developed proprietary software that is
designed to facilitate managing the productivity of personnel at the client's
work site. On-Premise offices are predominantly Company-owned. Since the concept
was introduced, revenues from On-Premise clients have grown to 18% of Commercial
Services revenues for the six months ended June 28, 1996.
 
    The Company has found that Interim On-Premise clients, which currently tend
to utilize Commercial Staffing services, are very receptive to other Interim
services, particularly in the Professional Services area. On-Premise managers
are well positioned to build on established relationships with key people at
client organizations to introduce Professional Services. Conversely,
Professional Services' employees often can identify instances where clients need
additional staffing services and introduce Interim On-Premise. Management
believes the Company's geographic and service breadth provide a strong
competitive advantage in securing such broad-reaching assignments.
 
    PROFESSIONAL SERVICES
 
    Professional Services offers a comprehensive range of consulting and
staffing services in the areas of IT, legal, accounting, search and human
resources. The Company provides personnel with skills in specialized
professional areas, including software analysts, computer programmers, network
administrators, attorneys, paralegals, court reporters, accountants and human
resource managers. In addition, the Company offers full-time placement,
recruiting, consulting and executive retained search services. The Company
believes that Professional Services tend to be less cyclical than traditional
flexible staffing
 
                                       24
<PAGE>
and that higher margins and cross-selling opportunities are associated with
these services. Management believes that Professional Services has substantial
growth opportunities, and therefore the Company will continue to target
disproportionate growth in these areas. Approximately 30% of the Company's total
revenues are currently derived from Professional Services.
 
    INFORMATION TECHNOLOGY. Through acquisitions made since the IPO, Interim has
built a leading information consulting and staffing services group operating
through 51 offices in the United States and two locations in the United Kingdom.
Now consolidated as Interim Technology, they provide a spectrum of strategic IT
services including consulting, flexible staffing and outsourcing services.
Interim Technology services can be subdivided into three specialty offerings,
Interim Search Solutions, the Consulting Group and the Staffing Solutions Group.
 
    Interim Search Solutions provides a range of search services for technology
specialties in positions up to and including Chief Information Officer. The
group offers both contingency and fully retained search services. Contingency
search results in payment only when a candidate has been placed at a company
whereas retained search, which is generally for senior management positions,
results in payments for services rendered, irrespective of placement.
 
    The Consulting Group specializes in the areas of software design,
development, quality assurance, implementation and management. The Group has
separate practices to supply specialized skills in the areas of client/server,
legacy systems, network integration, software quality management, systems
engineering and technical communications, and is a preferred skills provider for
leading IT product companies such as Microsoft, SAP and Novell. In addition, the
Consulting Group provides management of the significant conversions necessary to
correct many mainframe software's inability to recognize dates after December
31, 1999, the "millennium problem". The Consulting Group provides longer term
staffing and consulting services utilizing highly trained employees.
 
    The Staffing Solutions Group provides operations-based technical and
professional staffing and support for IT operations including help desk and data
center operations, operations analysis, communications, operations and PC
support. This group also offers a unique outsourcing service whereby its clients
maintain complete strategic control of their IT functions but are relieved of
technology staffing and performance issues. Management believes that this
service engenders a partnering relationship by providing the traditional savings
of outsourcing while enabling clients to preserve strategic control over their
information systems and data. The Staffing Solutions Group generally provides
large numbers of personnel for shorter assignments.
 
    LEGAL SERVICES. The Company's legal offices provide attorneys, paralegals,
court reporters, legal secretaries and deposition summary services predominantly
to law firms and corporations. In addition, the Company has a "Depolab" at its
corporate headquarters which utilizes proprietary software that permits law
firms to have depositions summarized into 13 different formats. The centralized
Depolab concept enhances supervision, confidentiality and quality control while
making better use of human resources which would otherwise be located in various
local offices.
 
    ACCOUNTING. Interim Accounting Professionals provides accounting and finance
personnel at all levels including bookkeepers, degreed accountants, certified
public accountants, auditors and controllers. The Company provides flexible
staffing and full-time placement capabilities for its clients.
 
    HUMAN RESOURCE SERVICES. Interim HR Solutions offices provide human resource
consulting and project management at client locations or on an outsourced basis.
In addition, skilled professionals such as contract recruiters and human
resource directors are available for project assignments. This group's expertise
ranges from organizational development and training to compensation, plan design
and benefits analysis.
 
HEALTHCARE DIVISION
 
    Health care staffing services includes providing general and specialized
health care skills and companionship in the home environment, as well as
providing the same health care skills in hospitals, nursing homes, HMOs and
other health care facilities. Management believes Interim is the second
 
                                       25
<PAGE>
largest health care staffing company in North America, based on sales. The
HealthCare Division provides a broad range of personnel including physicians,
nurses, therapists, home health aides and companions, occupational health and
on-site medical personnel. During 1995, 80% of the HealthCare Division's
revenues were derived from home care services, with the balance being derived
from Health Care Special Services for hospitals, clinics, nursing homes and
corporations with occupational health programs. Approximately 20% of the
Company's total revenues are currently derived from the HealthCare Division.
 
    HOME CARE
 
    Interim provides a comprehensive, integrated approach to home care. Primary
services include health aides, home companions and skilled nursing services.
Additional services include activities such as home infusion services and the
delivery of home medical equipment. Registered nurses and licensed practical
nurses perform full clinical procedures, including dispensing medication,
administering intravenous therapy and providing post-surgery wound care. In
addition, nurses examine and record patients' progress, provide patient
instructions and teaching, make periodic reports to the physicians in charge and
carry out physicians' instructions. Home health aides are trained to assist the
ill, elderly or disabled. Home companions visit patients in their homes to
provide companionship and attend to other social and personal needs.
 
    The trend towards home care services has resulted in an increase in the
portion of HealthCare revenues being remitted through Medicare and Medicaid.
Medicare business, for which the Company is only reimbursed for its costs, is
not a principal focus of the Company's strategy and represents approximately 5%
of the Company's revenues. Management believes that maintaining federal Medicare
certification is important, however, as it serves as a widely recognized
indicator of quality and standing in local communities and is important in
obtaining more profitable business.
 
    HEALTHCARE SPECIAL SERVICES
 
    INSTITUTIONAL STAFFING. The institutional staffing sector provides licensed
health care personnel for hospitals, nursing homes, HMOs and other health care
facilities. Hospitals utilize temporary nurses to augment core nursing staff
based on the number and condition of hospital patients, and for specialized
staffing needs such as in the intensive care unit, surgery or emergency room.
 
    LOCUM TENENS PHYSICIANS. Interim supplies temporary physicians to physician
groups and clinics, HMOs, and other facilities through nine regionally based
offices which provide complete coverage of the United States. With more offices
than any competitor, Interim is among the largest locum tenens staffing firms
providing primary care physicians in North America. This is a growing, high
margin business, and an example of the type of emerging special opportunities in
the health care industry on which the Company is focusing.
 
    THERAPY SERVICES. The Company's physical and respiratory therapists and
other similar health care professionals provide both home care and health care
staffing services to rehabilitation facilities, school systems, hospitals,
clinics, nursing homes and individuals needing home care all over the country.
These specially trained, licensed personnel are often in short supply, and as a
result, Interim recruits physical, occupational and speech therapists on a
world-wide basis. Interim also offers IN-STEP, a program through which the
Company helps finance overseas training of American students, who would
otherwise be unable to pursue a therapy degree because of the shortage of U.S.
schools offering therapy studies. Upon returning to the U.S. with their degree
and being licensed, these students become members of the Interim workforce for a
minimum of two years.
 
    OCCUPATIONAL HEALTH. In 1995, the Company launched Interim Occupational
Health which manages and staffs on-site clinics and medical health programs for
corporate clients, primarily Fortune 500 companies. Interim Occupational Health
assists companies in enhancing employee safety procedures, developing wellness
programs and implementing aggressive return-to-work policies. Such on-site
management is another example of the Company's services that allow its clients
to focus on their core competencies by reducing job related injuries, thereby
lowering costs and increasing productivity.

OFFICE STRUCTURE
 
    Interim offices are Company-owned, franchised and licensed. Most offices
serve multiple clients in their respective geographic area, with the exception
of Interim On-Premise sites which are established at the client's location to
serve only that client. The following table details the number of offices which
are Company-owned, franchised and licensed as of the end of the periods listed.

</TABLE>
 
    OWNED OFFICES
 
    As of June 28, 1996, the Company owned and operated 370 branch offices.
Branch office expansion is generally pursued in new markets or in markets where
Interim has an established presence and is used to increase market penetration.
Additional expansion is achieved by establishing On-Premise locations which tend
to be Company-owned. The Company intends to continue to expand Company-owned
branches in those locations where it can "cluster" multiple offices in close
geographic proximity to utilize centralized regional and area management and
other administrative functions, which leverages growth and increases
profitability.
 
    FRANCHISED OFFICES
 
    The Company has been granting franchises for more than 37 years. The average
tenure of franchise ownership exceeds 13 years, and a number of franchisees are
second generation owners. Most franchisees operate more than one franchise and
franchises are granted for the services offered by both Commercial Services and
HealthCare Divisions. While historically Commercial Services Division franchises
tend to be Commercial Staffing offices, the Company is beginning to offer
franchises for Professional Services offices as well. As of June 28, 1996, the
Company's 85 franchisees operated 426 franchised offices.
 
    The Company grants franchisees the exclusive right to market and furnish
commercial flexible staffing services, health care services or a particular
specialty or niche service within a designated geographic area using the
Company's trade names, service marks, advertising materials, sales programs,
operating procedures, manuals and forms. The Company provides franchises with
its national, regional and local advertising. Franchisees operate their
businesses autonomously within the framework of the Company's policies and
standards and recruit, employ and pay their own full-time and flexible staff.
The Company receives royalty fees from each franchise based upon its sales, and
in return supplies a variety of support and marketing services.
 
    For many years, the Company has had a secured loan program available to
franchisees for working capital or acquisition loans. The Company believes this
loan program has been an important factor in enhancing franchise growth. As of
June 28, 1996, the aggregate balance outstanding on all franchise loans was
$20.5 million.
 
    LICENSED OFFICES
 
    The Company also grants licenses, primarily in its Commercial Services
Division, which give the licensee the right to establish a business utilizing
the Company's trade names, service marks, advertising materials, sales programs,
operating procedures, manuals and forms within a designated territory. As of
June 28, 1996, the Company operated 178 licensed offices.
 
    Licensees are required to observe the Company's operating procedures and
standards and act as representatives of the Company in recruiting, screening,
classifying, employing and placing flexible staff
 
                                       27
<PAGE>
in response to client orders. The licensee is responsible for establishing the
office and paying related administrative and operating expenses, such as rent,
utilities and salaries of full-time employees. The Company is responsible for
paying the wages of the flexible staff and all related payroll taxes and
insurance. As a result, the Company provides a substantial portion of the
working capital needed for the licensed businesses. The Company has made a loan
program available to licensees similar to that available to franchisees,
although few licensees have accessed it to date.
 
    Sales by the licensed offices are included in the Company's revenues, and
the direct costs of services are included in the Company's cost of services. The
licensee receives a commission from the Company, which presently is equivalent
to 75% of the licensed offices' gross profits. The licensee is required to
participate in the Company's national advertising program and use the Company's
billing, payroll and other data processing services for which a separate fee is
paid to the Company.
 
    CORPORATE SUPPORT SERVICES
 
    FIELD SUPPORT. The Company maintains a strong national support system to
provide services, coordinate marketing and maintain consistent quality standards
throughout the Interim office network. The Company offers a variety of skill
development training for its personnel through Company-generated manuals and
corporate training programs for office management.
 
    CORPORATE SERVICE CENTER. The Company provides its decentralized branch
network with centralized functions for training, payroll, billing, receivables
management, credit and collections, risk management, legal support, cash
management, marketing and health care clinical operations. In addition, the
Company has developed its own proprietary software program called "TempLink" to
efficiently maintain client and flexible staff information, facilitate staffing
selection and payroll functions as well as provide testing software for
consistent skills testing and information management.
 
    HEALTHCARE CLINICAL OPERATIONS. The Company maintains quality control
standards through its national Clinical Operations Department. This department
sets Company-wide medical policies and procedures and establishes guidelines for
compliance with federal, state and local regulations in order to maintain
consistent quality in patient care. All Interim HealthCare offices have
registered nurses who provide supervision of patient care at the local level and
coordinate business strategy with the national organization. Further, as a part
of its overall strategy to become a full-service home care provider, Interim has
entered into a number of relationships with pharmaceutical and home medical
equipment vendors.
 
    CORPORATE MANAGED CARE AND MEDICARE EXPERTISE. During 1995, approximately
10% of the Company's revenues were derived from employer insurance plans, HMO
plans, indemnity insurance plans and private funds. The Company has worked in
tandem with many of the largest HMOs, insurance carriers and health care
facilities and has developed experience with per episode and capitated rates, as
well as traditional fee-for-service payment systems.
 
    Approximately 5% of the Company's 1995 revenues were from the Medicare
program and approximately 4% were from Medicaid programs. Proposals have been
advanced to change the current Medicare cost reimbursement scheme by
substituting a prospective payment plan. Most prospective payment proposals
would phase in a payment system under which providers would ultimately receive
payment on a "per episode" basis, with overall payment limits as well as the
opportunity for providers to share in savings to the extent program payments to
providers are less than annual aggregate limits. While there can be no assurance
that any such proposals will be implemented, nor any assurance as to the final
form of such legislation, Interim does not anticipate any adverse impact from
such changes because of its ability to manage its Medicare caseload and its
ability to keep its current Medicare service costs well below existing cost
caps.
 
SEASONALITY AND CYCLICALITY OF BUSINESS
 
    The Company's businesses are not seasonal in nature. The Company's
commercial business has historically been considered to be cyclical, often
acting as a coincidental indicator of both economic downswings and upswings.
However, as a result of general shifting of employment patterns and the
 
                                       28
<PAGE>
growth in On-Premise, this business is becoming less cyclical. In addition, the
Company's health care business is not cyclical and tends to dampen any cyclical
effects from the commercial sector. No single customer accounts for more than 1%
of the Company's revenues.
 
COMPETITION
 
    The flexible staffing industry is competitive with limited barriers to
entry. In addition to the Company, Manpower, Inc., Kelly Services, Inc., and the
Olsten Corporation are the principal national companies in the flexible staffing
industry. The Company also competes with CDI Corporation, Career Horizons, Inc.,
Accustaff, Inc., Robert Half International, Inc., Keane, Inc., COREStaff, Inc.,
Alternative Resources Corporation and Norrell Corporation, as providers of
flexible staffing in regional or specialty staffing markets and with a variety
of smaller, local providers of flexible staffing. No single competitor has more
than a 7% national market share, based on system-wide sales. The Company and the
Olsten Corporation are the principal national staffing companies providing
health care personnel. Management believes that, based on system-wide sales, the
Company is currently the fourth largest provider of staffing services in the
United States and is the seventh largest provider in the world.
 
    Management believes that the Company's size gives it an advantage over
smaller local competitors. As large companies and government agencies in the
commercial area and large insurance companies, hospitals and physician groups in
the health care area are increasingly contracting staffing services on a
national and regional basis, flexible staffing companies that lack a significant
presence may be at a disadvantage in bidding for this business.
 
TRADEMARKS
 
    In 1992, the Company changed its name and primary identifying trademarks
from "PERSONNEL POOL" and "MEDICAL PERSONNEL POOL" to "INTERIM" and the related
"INTERIM" marks described below. A few locations continue to operate under the
"MEDICAL PERSONNEL POOL" and "PERSONNEL POOL" marks (or related marks used by
such location prior to its acquisition by the Company). The Company has
undertaken extensive national and local advertising and marketing efforts to
increase its name recognition in the marketplace.
 
    The Company uses and has registered with the United States Patent and
Trademark Office the trademarks: INTERIM, INTERIM ACCOUNTING, INTERIM
HEALTHCARE, INTERIM PERSONNEL SERVICES, INTERIM IN-TOUCH, INTERIM LEGAL, INTERIM
ON-PREMISE, INTERIM PHYSICIANS, INTERIM THERAPY, DEPOSUMS, INTERPATH, TEMPLINK,
SKILL ANALYZER, TEMPORARY HEROS, INTERIM ASSISTED CARE, MEDICAL PERSONNEL POOL
and PERSONNEL POOL; it uses and has applications for registration pending for
the trademarks: INTERIM COURT REPORTING, INTERIM TECHNOLOGY, DEPOLAB, and
INTERIM ATTORNEYS; and it uses and claims ownership of the unregistered
trademarks: INTERIM CARE MANAGEMENT, INTERIM PERSONNEL, INTERIM FACILITIES
MANAGEMENT, INTERIM FINANCIAL PERSONNEL, INTERIM HOME CARE, INTERIM OCCUPATIONAL
HEALTH SERVICES, INTERIM MANAGED SERVICES, INTERIM OFFICE TECHNOLOGY, INTERIM
STAFFING and VICTOR PERSONNEL.
 
GOVERNMENTAL REGULATION
 
    Flexible staffing firms are generally subject to one or more of the
following types of government regulations: (i) regulation of the
employer/employee relationship between a firm and its flexible staff; (ii)
registration, licensing, record keeping and reporting requirements; and (iii)
substantive limitations on its operations. Flexible staffing firms are the legal
employers of their temporary workers. Therefore, the firm is governed by laws
regulating the employer/employee relationship, such as tax withholding or
reporting, social security or retirement, anti-discrimination and workers'
compensation.
 
    The Company's HealthCare Division is subject to periodic examinations by
government agencies and to extensive government regulation under federal, state
and local law, including licensing requirements, certificate of need
requirements, Medicare and Medicaid certification requirements, reimbursement
requirements, anti-fraud, anti-abuse and anti-kickback statutes and regulations,
and laws prohibiting physician ownership or compensation arrangements with home
care agencies. Health care providers are also subject to extensive documentation
requirements of government agencies and industry participants, such as insurance
companies and managed care companies. These regulations
 
                                       29
<PAGE>
can affect the ability of the Company to collect its fees for services provided.
There can be no assurance that the Company will be able to continue to obtain or
maintain the required governmental approvals or licenses, obtain reimbursement
for its services or avoid compliance or other problems under applicable laws and
regulations.
 
    The federal and state governments have enacted in the past, and will enact
in the future, laws and regulations that affect the provision of and
reimbursement for Medicare services by the Company. However, management believes
that because home care services and flexible staffing enable health care
providers to lower the cost of providing medical services, health care reform
may increase the use of flexible staffing and home care services, which are less
costly than institutional care.
 
    Currently, 193 Interim HealthCare locations (approximately 50%) are
accredited by the Joint Commission on Accreditation of Health Care Organizations
("JCAHO"). Applications for accreditation by the JCAHO are pending for
additional branch and franchised offices. Being accredited by the JCAHO can
simplify the process of becoming an approved home care provider under the
Medicare program and becoming licensed to provide home care services in some
states. The Company intends to seek JCAHO accreditation of all branch and
licensed offices and to encourage all franchised offices to do so as well.
 
    New York State requires the approval by the Public Health Council of the New
York State Department of Health ("NYPHC") of any changes in "the controlling
person" of an operator of a licensed health care services agency (a "LHCSA").
Control of an entity is presumed to exist if any person owns, controls or holds
the power to vote 10% or more of the voting securities of such entity. A person
seeking approval as a controlling person of an operator of a LHCSA must file an
application for NYPHC approval within 30 days of becoming a controlling person,
and pending a decision by the NYPHC, such person may not exercise control over
LHCSA. The Company has six offices in New York State which are LHCSAs. These
offices accounted for 2.3% of the Company's revenues during 1995. If any person
should become the owner or holder, or acquire control, or the right to vote 10%
or more of the common stock of the Company, such person could not exercise
control of the Company's LHCSAs until such ownership, control or holding has
been approved by the NYPHC.
 
    The Company's sale of franchises and licenses is regulated by the Federal
Trade Commission and by authorities in approximately 17 states and one Canadian
province. The Company must deliver a franchise offering circular (similar to a
prospectus) to prospective franchisees or licensees. The Company has either
filed the appropriate registration or obtained an exemption from registration in
states which require franchisors to register in order to sell franchises. The
Company does not anticipate that these requirements will have any material
effect on its ability to sell franchises or licenses.
 
LEGAL AND ADMINISTRATIVE PROCEEDINGS
    The Company, in the ordinary course of its business, is threatened with or
named as a defendant in various lawsuits, and the Company maintains insurance in
such amounts and with such coverage and deductibles as management believes are
reasonable and prudent. The principal risks that the Company insures against are
workers' compensation, personal injury, bodily injury, property damage,
professional malpractice, errors and omissions and fidelity losses.
 
EMPLOYEES
    The Company estimates that it placed approximately 380,000 flexible
personnel with clients in 1995, of which approximately 78,000 were placed, on
average, at any given time. In addition, the Company employs approximately 3,300
staff employees at its corporate headquarters, field offices and national
processing center.

                          DESCRIPTION OF CAPITAL STOCK
 
    The Company's authorized capital stock consists of 52,500,000 shares of
which 50,000,000 shares are Common Stock (the "Common Stock") and 2,500,000
shares are Preferred Stock (the "Preferred Stock"). As of June 28, 1996, there
were 15,464,351 issued and outstanding shares of Common Stock as adjusted, and
approximately 1,915,931 additional shares of Common Stock are reserved for
issuance upon the exercise of stock options that have been or may be granted
under the Company's stock option plans. As of June 28, 1996, there were no
issued and outstanding shares of Preferred Stock. On September 9, 1996, the
Company's Stockholders approved an amendment to the Company's Restated
Certificate of Incorporation to increase the number of authorized shares of
Common Stock from 25,000,000 to 50,000,000.
 
COMMON STOCK
 
    Generally, the vote of the holders of a majority of all shares of stock of
the Company voting (whether in person or by proxy) on a matter will decide such
matter, unless express provisions of law or the Company's Restated Certificate
of Incorporation require a different vote. All shares of Common Stock are deemed
to be voting stock of the Company, and all holders thereof are entitled to one
vote for each share of stock standing in their names. Holders of Common Stock
have no preemptive rights to purchase or subscribe for any stock or other
securities of the Company. The outstanding Common Stock is fully paid and
non-assessable. Each holder of Common Stock on the applicable record date is
entitled to receive such dividends as may be declared by the Board of Directors
at any meeting out of funds legally available therefor. No dividend or other
distribution with respect to the Common Stock has ever been paid by the Company,
other than in connection with the stockholder rights plan discussed below and by
Brandon prior to the Brandon Merger. The Company currently intends to retain any
earnings for use in its business and does not anticipate paying any cash
dividends in the foreseeable future.
 
    The Company has in place a stockholder rights plan designed to deter
coercive or unfair takeover tactics and to prevent a potential acquirer from
gaining control of the Company without offering a fair price. Under the plan, a
dividend of one right (a "Right") per share was declared and paid on each share
of Common Stock outstanding on April 1, 1994 and with respect to shares of
Common Stock issued after such date, Rights will automatically attach to them
upon their issuance. Under the plan, holders of each Right may purchase from the
Company one one-hundredth of a share of a new class of Preferred Stock, par
value $.01 per share, at a price of $98.00, subject to adjustment, when the
Rights become exercisable. The Rights become exercisable after a public
announcement that, without the prior written consent of the Company's Board of
Directors, a person, together with all affiliates and associates of such person,
shall become the beneficial owner of 15% or more of the then outstanding shares
of Common Stock (an "Unapproved Stock Acquisition"), and after ten business days
following the commencement of, or the public announcement of an intention to
commence, a tender or exchange offer that would result in an Unapproved Stock
Acquisition. If a person or group of persons makes an Unapproved Stock
Acquisition, the registered holder of each Right has the right to receive upon
exercise, in lieu of Preferred Stock, that number of shares of Common Stock
having a market value equal to twice the exercise price of the Right (a
"Subscription Right"). Following an Unapproved Stock Acquisition, if the Company
is involved in a merger, or 50% or more of the Company's assets or earning power
are sold, the registered holder of each Right has the right to receive upon
exercise, in lieu of Preferred Stock, that number of shares of the common stock
of the acquiring company having a market value equal to twice the exercise price
of the Right (a "Merger Right"). After an Unapproved Stock Acquisition, but
before any person or group of persons, together with all affiliates and
associates of such person, shall become the beneficial owner of 50% or more of
the outstanding shares of Common Stock, the Board of Directors may exchange all
or part of the then outstanding and exercisable Rights for Common Stock at an
exchange ratio of one share of Common Stock per Right. Upon any such exchange,
the right of any holder to exercise a Right terminates. The Company may redeem
the Rights at a price of $.01 per Right at any time prior to an Unapproved Stock
Acquisition (and after such time in certain circumstances). The Rights expire on
April 1, 2004, unless extended by the Board of Directors, redeemed or exchanged
by the Company or
 
                                       34
<PAGE>
after the consummation of a permitted merger transaction. Until a Right is
exercised, the holder thereof, as such, has no rights as a stockholder of the
Company, including the right to vote or to receive dividends. The issuance of
the Rights alone has no dilutive effect and does not affect reported earnings
per share.
 
PREFERRED STOCK
 
    The Company's Board of Directors has the authority to issue up to 2,500,000
shares of Preferred Stock, par value $.01 per share, in one or more series and
to fix, by resolution, the number of shares constituting any such series, the
designations, preferences and relative, participating, optional or other special
rights and qualifications, limitations or restrictions thereof, including the
dividend rights, dividend rates, terms of redemption (including sinking fund
provisions), redemption prices, conversion rights, amounts payable on
liquidation and liquidation preferences of the shares constituting any series,
without any further vote or action by the stockholders. No shares of Preferred
Stock are outstanding. Any shares of Preferred Stock so authorized and issued
would have priority over the Common Stock with respect to dividend and
liquidation rights.
 
CERTAIN EFFECTS OF AUTHORIZED BUT UNISSUED STOCK
 
    The Company's authorized but unissued shares are available for future
issuance without stockholder approval. These additional shares may be utilized
for a variety of proper corporate purposes, including future public offerings to
raise additional capital, to facilitate corporate acquisitions and for employee
benefit plans.
 
    One of the effects of the existence of unissued and unreserved Preferred
Stock and Common Stock may be to enable the Company's Board of Directors to
issue shares to persons friendly to current management which could render more
difficult or discourage an attempt to obtain control of the Company by means of
a merger, tender offer, proxy contest or otherwise, and thereby protect the
continuity of the Company's management. Issuance of Preferred Stock might, under
certain circumstances, deter the acquisition of the Company or its securities by
a person concerned about the terms or effect of such Preferred Stock.

    The validity of the shares of Common Stock offered hereby will be passed

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors
of Interim Services Inc.
Fort Lauderdale, Florida
 
    We have audited the accompanying consolidated balance sheets of Interim
Services Inc. and subsidiaries as of December 30, 1994 and December 29, 1995,
and the related consolidated statements of earnings, stockholders' equity and
cash flows for each of the three years in the period ended December 29, 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, such consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Interim
Services Inc. and subsidiaries as of December 30, 1994 and December 29, 1995,
and the results of their operations and their cash flows for each of the three
years in the period ended December 29, 1995, in conformity with generally
accepted accounting principles.
 
    We previously audited and reported on the consolidated financial statements
of Interim Services Inc. as of December 30, 1994 and December 29, 1995 and for
each of the three years in the period ended December 29, 1995, prior to their
restatement for the merger with Brandon Systems Corporation as described in Note
3 to the consolidated financial statements. The accompanying consolidated
financial statements give retroactive effect to the merger of Brandon Systems
Corporation with Interim Services Inc. on May 23, 1996, which has been accounted
for as a pooling-of-interests.

                       (IN THOUSANDS, EXCEPT SHARE DATA)
 
1.  ORGANIZATION
 
    HISTORY -- Prior to January 27, 1994, the effective date of its initial
public offering, Interim Services Inc. ("Interim" or the "Company") was a
wholly-owned subsidiary of H&R Block, Inc. ("Block"). On January 27, 1994, Block
completed the sale at $20 per share of 10 million shares of Interim, its entire
holdings. On January 28, 1994, Interim's shares commenced trading on the Nasdaq
National Market. In addition, the underwriters for the offering exercised their
over-allotment option and purchased from Interim an additional 1.5 million
shares at $20 per share. The net proceeds to Interim were $28,275.
 
    Prior to September 25, 1993, the Company's working capital and acquisition
financing were provided by Block. There was no interest charged on intercompany
debt. Effective September 25, 1993, Block formalized this arrangement by (i)
providing a revolving credit facility in the amount of $20,000 to fund the
operating requirements of Interim; (ii) converting $30,000 of intercompany
indebtedness on such date to a term loan, and (iii) contributing $51,289 to the
capital of Interim. The supplemental earnings data for the year ended December
24, 1993 (unaudited) gives effect to this arrangement as if it occurred at the
beginning of the period. Interest expense has been computed at 6% and income
taxes at the statutory rate.
 
    BUSINESS -- The Company is a leader in providing a comprehensive range of
customized staffing solutions, including flexible staffing, home care, full-time
placement, consulting and other value-added services on a national basis to
businesses, professional and service organizations, governmental agencies,
health care facilities and individuals. As of June 28, 1996, the Company
operated through a network of offices in the U.S., Canada and the United
Kingdom.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    BASIS OF PRESENTATION -- The consolidated financial statements include the
accounts of Interim and Brandon Systems Corporation ("Brandon") (a wholly-owned
subsidiary of Interim), collectively referred to as the Company. As discussed in
Note 3, on May 23, 1996, Brandon became a wholly-owned subsidiary of Interim.
These consolidated financial statements have been prepared under the pooling-of-
interests method of accounting and reflect the combined financial position and
operating results of Interim and Brandon for all periods presented. There were
no significant intercompany transactions during the periods covered by these
consolidated financial statements.
 
    PRINCIPLES OF CONSOLIDATION -- The consolidated financial statements include
the accounts of the Company and its wholly-owned subsidiaries. All material
intercompany transactions and balances have been eliminated.
 
    PERVASIVENESS OF ESTIMATES -- The preparation of financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
    FISCAL YEAR -- The Company's fiscal year is comprised of 52 or 53 weeks,
ending on the last Friday in December. The year ended December 30, 1994
contained 53 weeks and the years ended December 29, 1995 and December 24, 1993
contained 52 weeks.
 
    INTANGIBLE ASSETS -- The excess of cost of franchise and independent offices
acquired over the fair value of net assets acquired is being amortized on a
straight-line basis over various periods averaging

                       (IN THOUSANDS, EXCEPT SHARE DATA)
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
approximately 29 years. The Company evaluates the recoverability of its
investments in such intangible assets in relation to anticipated cash flows on
an undiscounted basis. If the estimated future cash flows are projected to be
less than the carrying value, an impairment write-down would be recorded.
 
    REVENUES -- The Company generates revenues from sales by its own branch and
licensed operations and from royalties earned on sales by its franchise
operations. Franchise royalties, which are included in revenues, were $20,458,
$22,790 and $24,316 for the years ended December 24, 1993, December 30, 1994 and
December 29, 1995, respectively, and $11,813 and $13,093 for the six months
ended June 30, 1995 and June 28, 1996, respectively. Revenues and the related
labor costs and payroll taxes are recorded in the period in which the service is
performed.
 
    The Company utilizes two forms of franchising agreements. Under the first
form, the Company records franchise royalties, based upon the contractual
percentage of franchise sales, in the period in which the franchise provides the
service. Under the second form (termed "license" by the Company), revenues
generated by the franchisee operations and related direct costs are included as
part of the Company's revenues from services and cost of services, respectively.
The net distribution paid to the licensee is based upon a percentage of the
gross profit generated, and is captioned "licensee commissions" in the
Consolidated Statements of Earnings.
 
    Revenues generated from the sales of licenses and franchises are recognized
when the Company has performed substantially all of its obligations under its
franchise agreements and when collectibility of such amounts is reasonably
assured.
 
    MARKETABLE SECURITIES -- Marketable securities, which consist of tax-exempt
securities issued by various state agencies and their political subdivisions,
and U.S. Treasury Notes, have been categorized as available for sale and, as a
result, are stated at fair value. Unrealized gains and losses are included as a
component of stockholders' equity until realized.
 
    DEPRECIATION AND AMORTIZATION -- Buildings and equipment are depreciated
over the estimated useful lives of the assets using the straight-line method.
Leasehold improvements are amortized over the shorter of their estimated useful
life or the lease term using the straight-line method. Maintenance and repairs
are expensed as incurred. Expenditures which significantly increase the value of
the assets or extend useful lives are capitalized.
 
    WORKERS' COMPENSATION BENEFITS -- The Company's workers' compensation
coverage is retrospectively rated based upon ultimate incurred losses and loss
adjustment expenses. Workers' compensation costs are accrued based upon the
aggregate of the liability for reported claims and loss adjustment expenses and
an actuarially determined estimated liability for claims incurred but not
reported.
 
    INCOME TAXES -- The Company accounts for income taxes in accordance with the
provisions of Statement of Financial Accounting Standards No. 109 ("SFAS No.
109"), "Accounting for Income Taxes". SFAS No. 109 provides that income taxes
are accounted for using an asset and liability method which requires the
recognition of deferred tax assets and liabilities for expected future tax
consequences of temporary differences, which are not material, between tax bases
and financial reporting bases of assets and liabilities.

                       (IN THOUSANDS, EXCEPT SHARE DATA)
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    The Company has entered into an income tax sharing agreement with Block to
provide for the payment of taxes for periods prior to January 27, 1994, during
which Block and the Company filed a consolidated federal income tax return, and
whereby Block shall be liable for, and shall hold the Company harmless against,
any liability for income taxes for any period prior to January 27, 1994.
 
    EARNINGS PER SHARE -- Earnings per share and supplemental earnings per share
(see Note 1) are computed based upon the weighted average number of common and
common equivalent shares outstanding, adjusted for the exchange ratio of the
merger described in Note 3. Earnings per share and supplemental earnings per
share, assuming full dilution, have not been shown as there would be no material
dilution.
 
    ALLOWANCE FOR DOUBTFUL ACCOUNTS -- The Company carries accounts and notes
receivable at the amount it deems to be collectible. Accordingly, the Company
provides allowances for accounts and/or notes receivable it deems to be
uncollectible based on management's best estimates. Recoveries are recognized in
the period they are received. The ultimate amount of accounts and/or notes
receivable that become uncollectible could differ from those estimated.
 
    CONSOLIDATED STATEMENTS OF CASH FLOWS -- For purposes of the Consolidated
Statements of Cash Flows, the Company considers all highly liquid debt
instruments purchased with an original maturity of three months or less to be
cash equivalents.
 
    DISCLOSURE REGARDING FINANCIAL INSTRUMENTS -- The carrying amounts of cash
and cash equivalents, accounts receivable, accounts payable and accrued expenses
approximate fair value due to the relatively short maturity of the respective
instruments.
 
    The carrying amounts of notes payable to banks and long-term debt
obligations issued pursuant to the Company's bank credit agreements and
revolving credit facility approximate fair value because the interest rates on
these instruments change with market interest rates.
 
    NEW ACCOUNTING STANDARDS -- In March 1995, the Financial Accounting
Standards Board ("FASB") issued SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of." SFAS No. 121
establishes accounting standards for the impairment of long-lived assets,
certain identifiable intangibles and goodwill related to those assets to be held
and used and for long-lived assets and certain identifiable intangibles to be
disposed of. SFAS No. 121 requires that long-lived assets and certain
identifiable intangibles to be held and used by an entity be reviewed for
impairment whenever events or changes in circumstances indicated that the
carrying amount of an asset may not be recoverable. The Company adopted SFAS No.
121 during the quarter ended March 29, 1996. The adoption of this statement did
not have a material impact on the Company's financial position or results of
operations.
 
    The FASB has also issued SFAS No. 123, "Accounting for Stock-Based
Compensation". This statement defines a fair value based method of accounting
for an employee stock option. This statement also permits a company to continue
to measure compensation costs for their stock option plan using the intrinsic
value based method of accounting prescribed by Accounting Principles Board
("APB") Opinion No. 25, "Accounting for Stock Issued to Employees". SFAS No. 123
requires disclosure of the pro forma net income and earnings per share that
would be reported if the fair value method was utilized. The Company plans to
continue to utilize the provisions of APB No. 25 to account for such
compensation costs, and will provide the pro forma disclosures required by SFAS
No. 123 in their 1996 financial statements.

3.  THE BRANDON SYSTEMS MERGER
    On May 23, 1996, the Company completed its merger with Brandon Systems
Corporation, an information technology staffing company. The Company issued
3,872,690 shares of its common stock in exchange for 100% of the outstanding
shares of Brandon common stock. In addition, Brandon stock options outstanding
at the effective time of the merger were converted into options to purchase an
aggregate of 207,592 additional Interim common shares.
 
    The merger has been accounted for as a pooling-of-interests for accounting
and financial reporting purposes. The pooling-of-interests method of accounting
is intended to present as a single interest two or more common shareholders'
interests which were previously independent; accordingly, the historical
financial statements for the periods prior to the merger are restated as though
the companies had been combined. The restated financial statements are adjusted
to conform the accounting policies of the combined companies and fiscal
reporting periods of the Company.
 
    All fees and expenses related to the merger and the consolidation and
restructuring of the combined companies have been expensed as required under the
pooling-of-interests accounting method and are reflected in the consolidated
statements of earnings for the period ending June 28, 1996. Such fees and
expenses approximate $8,600 ($7,555 after tax) and include investment banking,
legal and accounting fees, severance and benefit-related costs, and other costs
of consolidating operations.
 
    The following summarizes amounts previously reported by Interim and Brandon
prior to the transaction:

7.  CREDIT FACILITIES
 
    SHORT-TERM:
 
    The Company has unsecured, uncommitted lines of credit with several banks
based on LIBOR and available to fund the Company's short-term capital
requirements. As of December 29, 1995 and June 28, 1996, the Company had
borrowings outstanding of $54,727 and $60,000, respectively, under these
agreements.
 
    LONG-TERM:
 
    On April 6, 1994, the Company replaced a $30,000 term loan and a $20,000
revolving credit facility with a new five-year $50,000 committed senior
revolving credit agreement. In November, 1995, this facility was increased to
$150,000. This credit facility is available to fund the Company's general
corporate needs, to fund working capital and to fund acquisitions. Interest
charged on the facility is based, at the Company's option, on either the banks'
base rate or LIBOR plus an applicable margin. The margin changes based on the
Company's leverage and fixed charge ratios. The facility contains customary
covenants, which include the maintenance of certain financial ratios including
minimum net worth, restrictions on the incurrence of liens and additional
indebtedness. This facility terminates on April 6, 1999. As of December 29, 1995
and June 28, 1996, the Company had borrowings outstanding of $60,000 under this
facility, and was in compliance with all of its terms.

9.  EMPLOYEE BENEFIT PLANS
    The Company and Brandon each maintain voluntary defined contribution 401(k)
profit sharing plans covering all eligible employees as defined in the
respective plan documents. For Interim employees, the plan provides a
discretionary matching contribution of up to 25% of employee contributions up to
6% of compensation contributed by eligible employees. In years when budget
objectives are attained, the plan provides for up to an additional 25% matching
contribution payable in Interim Common Stock. For Brandon employees, the
discretionary matching contribution permitted by the plan is equal to 25% of the
first 6% of compensation contributed by eligible full-time salaried employees.
In addition, each year the Company may elect to make a profit sharing
contribution to eligible full-time salaried employees. Additionally, the Company
had sponsored a profit sharing plan for Interim employees who had completed
1,000 hours of service within a twelve month period. The profit sharing plan was
non-contributory, with amounts funded for the benefit of qualifying employees
determined annually by the Company's Board of Directors on a discretionary
basis. The Company's Board of Directors voted to terminate the profit sharing
plan effective December 31, 1993. Contributions, net of forfeitures, by the
Company under these plans amounted to $611, $756 and $666 for the years ended
December 24, 1993, December 30, 1994 and December 29, 1995, respectively, and
$552 and $881 for the six months ended June 30, 1995 and June 28, 1996,
respectively.
 
    During 1995, the Company started a deferred compensation plan for selected
highly compensated employees who are not eligible to participate in the
Company's 401(k) savings plan. The plan allows eligible employees to defer
receipt of a portion (not less than 2 percent nor more than 10 percent) of their
compensation. The Company provides a discretionary matching contribution of up
to 25% of employee contributions up to 6 percent. In years when budget
objectives are attained, the Company provides an additional 25% matching
contribution. The matching contributions vest on a graduated scale from two to
five years of service. The deferred compensation, along with the Company
matching amounts and accumulated investment earnings, is accrued but unfunded.
Such accrual amounted to $710 and $1,343 at December 29, 1995 and June 28, 1996,
respectively. Contributions by the Company under this plan amounted to $149, $19
and $161 for the year ended December 29, 1995, and the six months ended June 30,
1995 and June 28, 1996, respectively.
 
10. STOCKHOLDERS' EQUITY AND STOCK OPTION PLANS
 
    STOCK OPTIONS -- The Company has three stock option plans: the 1993
Long-Term Executive Compensation Plan, the 1993 Stock Option Plan for Outside
Directors and the 1994 Stock Option Plan for Franchisees, Licensees and Agents.
Under the plans, options may be granted to outside directors, selected employees
and franchisees, licensees and agents to purchase the Company's common stock for
periods not to exceed ten years at a price that is not less than 100 percent of
fair market value on the

date of grant. Options under the Long-Term Executive Compensation Plan are
exercisable (if certain qualifying criteria are met) starting one year from the
date of grant on a cumulative basis at the annual rate of 33 1/3 percent of the
total number of optioned shares. Options under the Outside Directors Plan are
exercisable in full one year after the date of grant. Options under the
Franchisees, Licensees and Agents Plan are exercisable starting one year from
the date of grant on a cumulative basis at an annual rate that varies during the
first five years of the options' term at which time they become fully
exercisable. In October, 1993, the Company reserved a total of 1,000,000 shares,
and on May 11, 1995, and May 9, 1996, an additional total of 350,000 and 450,000
shares, respectively, of common stock for issuance under the foregoing plans. On
January 27, 1994, the first options under these plans were granted.
 
    As described in Note 3, prior to the merger Brandon had also adopted a stock
option plan, under which 235,900 options to purchase its common shares were
outstanding and unexercised at the date of the Merger. Such options were
converted into options to purchase an aggregate of 207,592 shares of the
Company's common stock at a price equivalent (after conversion) to the original
grant price (which was not less than the estimated fair value of Brandon common
stock at grant date). Changes under these plans for 1994 and 1995 giving
retroactive effect to the conversion of the Brandon stock options upon their
original grant dates were as follows:

its common stock for $1,805. In 1990, Brandon's Board of Directors had
authorized the repurchase of up to $2 million of common stock as market
conditions may warrant. The aggregate number of shares repurchased through
October 26, 1995 were 116,700 for a total consideration of $1,923. Such treasury
stock was cancelled upon consummation of the merger.
 
    EMPLOYEE STOCK PURCHASE AND DIVIDEND REINVESTMENT AND STOCK PURCHASE PLANS

11. STOCKHOLDER RIGHTS PLAN
    On February 17, 1994, the Company's Board of Directors adopted a stockholder
rights plan to deter coercive or unfair takeover tactics and to prevent a
potential acquirer from gaining control of the Company without offering a fair
price to all of the Company's stockholders. Under the plan, a dividend of one
right (a "Right") per share was declared and paid on each share of the Company's
Common Stock outstanding on April 1, 1994. As to shares issued after such date,
rights will automatically attach to them after their issuance.
 
    Under the plan, registered holders of each Right may purchase from the
Company one one-hundredth of a share of a new class of the Company's Preferred
Stock, $0.01 par value per share, at a price of $98.00, subject to adjustment,
when the Rights become exercisable. The Rights become exercisable when a person
or group of persons acquires 15% or more of the outstanding shares of the
Company's Common Stock without the prior written approval of the Company's Board
of Directors (an "Unapproved Stock Acquisition"), and after ten business days
following the commencement of a tender offer that would result in an Unapproved
Stock Acquisition. If a person or group of persons makes an Unapproved Stock
Acquisition, the registered holder of each Right has the right to purchase, for
the exercise price of the Right, a number of shares of the Company's Common
Stock having a market value equal to twice the exercise price of the Right.
Following an Unapproved Stock Acquisition, if the Company is involved in a
merger, or 50% or more of the Company's assets or earning power are sold, the
registered holder of each Right has the right to purchase, for the exercise
price of the Right, a number of shares of the common stock of the acquiring
company having a market value equal to twice the exercise price of the Right.
 
    After an Unapproved Stock Acquisition, but before any person or group of
persons acquires 50% or more of the outstanding shares of the Company's Common
Stock, the Board of Directors may exchange all or part of the then outstanding
and exercisable Rights for Common Stock at an exchange ratio of one share of
Common Stock per Right. Upon any such exchange, the right of any holder to
exercise a Right terminates.
 
    The Company may redeem the Rights at a price of $0.01 per Right at any time
prior to an Unapproved Stock Acquisition (and after such time in certain
circumstances). The Rights expire on April 1, 2004, unless extended by the Board
of Directors. Until a Right is exercised, the holder thereof, as such, has no
rights as a stockholder of the Company, including the right to vote or to
receive dividends. The issuance of the Rights alone has no dilutive effect and
does not affect reported earnings per share.
 
12. ACQUISITIONS
    Effective December 1, 1995, Interim acquired the assets of Computer Power
Group, a subsidiary of Australia-based Computer Power Group, Ltd., for $71
million in cash. Computer Power Group provides staffing and consulting services
in a variety of information technology disciplines. This acquisition was
accounted for under the purchase method of accounting. Accordingly, the
operations of CPG are included in the consolidated statements of earnings from
the date of acquisition. The excess of the purchase price over the fair value of
the net tangible assets acquired (goodwill) was $56,618 and is being amortized
over 40 years.
 
    During 1993, 1994 and 1995, the Company made certain other acquisitions
which were accounted for under the purchase method of accounting. Their
operations are included in the consolidated statements of earnings from the date
of acquisition. Had the acquisitions during 1993 and 1994 taken place at the
beginning of the year in which they occurred, pro forma operating results would
not have been significantly different from those reported.

13. TRANSACTIONS WITH BLOCK
    The Company and Block, or an affiliate of Block, had engaged in the
following transactions or are parties to the contracts or business relationships
described below.
 
    DUE TO BLOCK -- Amounts due to Block consisted of cash advances for
purchases of property and equipment, acquisitions, current income tax
liabilities and fluctuating working capital needs, offset by payments made by
the Company from its operating bank accounts. Block did not charge the Company
interest expense on any balance due. During the year ended December 24, 1993 the
average balance of amounts due Block was $84,018.
 
    CAPTIVE INSURANCE PROGRAM -- The Company has historically purchased workers'
compensation, general liability, errors and omissions, and property and casualty
insurance from various insurance companies. The Company has purchased its
workers' compensation insurance coverage and its general liability and errors
and omissions insurance coverage from an insurance company that has a
reinsurance agreement with an affiliate of Block commencing January 1, 1994 and
June 1, 1993, respectively. Certain of the Company's franchisees also
participate in the same insurance program. The premiums for coverages provided
by the insurance company to the Company and its licensees for the years ended
December 24, 1993, December 30, 1994 and December 29, 1995, aggregated $1,600,
$3,300 and $1,400, respectively for general liability and errors and omissions
coverage and $0, $14,600 and $5,600, respectively for workers' compensation
coverage, subject to certain adjustments based on actual loss experience.
 
    BLOCK GUARANTEE OF FRANCHISE OBLIGATIONS -- For purposes of enabling the
Company to register to sell franchises in certain states, Block guaranteed the
performance of the Company's obligations as franchisor under its franchise
agreements. Subsequent to the closing of the public offering, Block no longer
guarantees the Company's obligations to new franchisees. Each previously
existing guarantee will terminate at the end of the term of the applicable
franchise agreement, with such termination of the guarantee being effective upon
the granting of a renewal by the Company (or election by the franchisee to
exercise its option to renew the franchise).
 
    INDEMNIFICATION AGREEMENT -- The Company and Block have entered into an
Indemnification Agreement, whereby the Company has agreed to indemnify Block
against losses incurred by Block arising from the conduct of the Company's
business subsequent to January 27, 1994. This indemnification obligation
includes any liability incurred by Block pursuant to Block's guarantee of the
Company's obligation as franchisor under the Company's franchise agreements.

14. COMMITMENTS
    Substantially all of the Company's operations are conducted in leased
premises. The Company leases off-site corporate related office space and branch
and regional processing center locations. Total lease expense for the years
ended December 24, 1993, December 30, 1994 and December 29, 1995 was $7,399,
$7,418 and $8,585, respectively, and $4,138 and $5,587 for the six months ended
June 30, 1995 and June 28, 1996, respectively.
 
    Future minimum lease payments under noncancellable leases as of December 29,
1995 were as follows:

15. CONTINGENCIES
    The Company in the ordinary course of its business is threatened with or
named as a defendant in various lawsuits. It is not possible to determine the
ultimate disposition of these matters; however, management is of the opinion
that the final resolution of any threatened or pending litigation is not likely
to have a material adverse effect on the financial position or results of
operations of the Company.

</TABLE>
 
    Under the terms and conditions of the Underwriting Agreement, the U.S.
Underwriters are committed to take and pay for all of the shares offered hereby,
if any are taken.
 
    The U.S. Underwriters propose to offer the shares of Common Stock in part
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus and in part to certain securities dealers at such
price less a concession of $         per share. The U.S. Underwriters may allow,
and such dealers may reallow, a concession not in excess of $         per share
to certain brokers and dealers. After the shares of Common Stock are released
for sale to the public, the offering price and other selling terms may from time
to time be varied by the representatives.
 
    The Company and the Selling Stockholders have entered into an underwriting
agreement (the "International Underwriting Agreement") with the underwriters of
the international offering (the "International Underwriters") providing for the
concurrent offer and sale of shares of Common Stock in an international offering
outside of the United States. The offering price and aggregate underwriting
discounts and commissions per share for the two offerings are identical. The
closing of the offering made hereby is a condition to the closing of the
international offering, and vice versa. The representatives of the International
Underwriters are Goldman Sachs International, Robert W. Baird & Co. Incorporated
and Donaldson, Lufkin & Jenrette Securities Corporation.
 
    Pursuant to an Agreement between the U.S. and International Underwriting
Syndicates (the "Agreement Between") relating to the two offerings, each of the
U.S. Underwriters has agreed that, as part of the distribution of the shares
offered hereby and subject to certain exceptions, it will offer, sell or deliver
the shares of Common Stock, directly or indirectly, only in the United States of
America (including the States and the District of Columbia), its territories,
its possessions and other areas subject to its jurisdiction (the "United
States") and to U.S. persons, which term shall mean, for purposes of this
paragraph: (a) any individual who is a resident of the United States or (b) any
corporation, partnership or other entity organized in or under the laws of the
United States or any political subdivision thereof and whose office most
directly involved with the purchase is located in the United States. Each of the
International Underwriters named herein has agreed pursuant to the Agreement
Between that, as a part of the distribution of the shares offered as a part of
the international offering, and subject to certain exceptions, it will (i) not,
directly or indirectly, offer, sell or deliver shares of Common Stock (a) in the
 
                                      U-1
<PAGE>
United States or to any U.S. persons or (b) to any person who it believes
intends to reoffer, resell or deliver the shares in the United States or to any
U.S. persons, and (ii) cause any dealer to whom it may sell such shares at any
concession to agree to observe a similar restriction.
 
    It is anticipated that more than 10% of the proceeds of the Offering, not
including underwriting compensation, will be received by lenders to the Company
under the Credit Facilities that are affiliated with members of the National
Association of Securities Dealers, Inc. ("NASD") who are participating in the
Offering. As a result, the Offering is being conducted pursuant to Rule
2710(c)(8) of the NASD Conduct Rules.
 
    Pursuant to the Agreement Between, sales may be made between the U.S.
Underwriters and the International Underwriters of such number of shares of
Common Stock as may be mutually agreed. The price of any shares so sold shall be
the initial public offering price less an amount not greater than the selling
concession.
 
    The Company has granted the U.S. Underwriters an option exercisable for 30
days after the date of this Prospectus to purchase up to an aggregate of 510,000
additional shares of Common Stock solely to cover over-allotments, if any. If
the U.S. Underwriters exercise their over-allotment option, the Underwriters
have severally agreed, subject to certain conditions, to purchase approximately
the same percentage thereof that the number of shares to be purchased by each of
them, as shown in the foregoing table, bears to the 4,250,000 shares of Common
Stock offered. The Company has granted the International Underwriters a similar
option exercisable up to an aggregate of 127,500 additional shares of Common
Stock.
 
    The Company and the Selling Stockholders have agreed that during the period
beginning from the date of this Prospectus and continuing to and including the
date 90 days after the date of this Prospectus, not to offer, sell, contract to
sell or otherwise dispose of any securities of the Company (other than pursuant
to employee stock option plans, employee stock purchase plans, 401(k) plans or
any other employee plans of a similar nature, including, without limitations,
any such plans for the benefit of directors or officers of the Company, which
are described in the Prospectus, existing on the date of this Prospectus and
10,000 of the shares held by the Ira B. Brown Foundation, Inc., a charitable
institution) which are substantially similar to the shares of Common Stock,
including but not limited to any securities that are convertible into or
exchangeable for, or that represent the right to receive, Common Stock or any
substantially similar security, without the prior written consent of the
Representatives, except for the shares of Common Stock offered in connection
with the concurrent U.S. and international offerings.
 
    The representatives of the Underwriters have informed the Company that they
do not expect sales to accounts over which the Underwriters exercise
discretionary authority to exceed five percent of the total number of shares of
Common Stock offered by them.
 
    The Company and the Selling Stockholders have severally agreed to indemnify
the several Underwriters against certain liabilities, including liabilities
under the Securities Act of 1933, as amended.

    SIXTH: (A) The Corporation shall indemnify to the fullest extent authorized
or permitted by law (as now or hereafter in effect) any person made, or
threatened to be made a party or witness to any action, suit or proceeding
(whether civil or criminal or by or in the right of the Corporation) by reason
of the fact that he, his testator or intestate, is or was a director or officer
of the Corporation or by reason of the fact that such director or officer, at
the request of the Corporation, is or was serving any other corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise, in
any capacity. Nothing contained herein shall affect any rights to
indemnification to which employees other than directors and officers may be
entitled by law. No amendment to or repeal of this paragraph (A) of Article
Sixth shall apply to or have any effect on any right to indemnification provided
hereunder with respect to any acts or omissions occurring prior to such
amendment or repeal.
 
    (B) No director or shareholder of the Corporation shall be personally liable
to the Corporation or its shareholders for monetary damages for any breach of
fiduciary duty as a director. Notwithstanding the foregoing sentence, a director
shall be liable to the extent provided by applicable law (i) for any breach of
the director's duty of loyalty to the Corporation or its shareholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) pursuant to Section 174 of the General
Corporation Law of the State of Delaware, or (iv) for any transaction from which
such director derived an improper personal benefit. No amendment to or repeal of
this paragraph (B) of Article Sixth shall adversely affect any right or
protection of any director of the Corporation existing at the time of such
amendment to repeal for or with respect to any acts or omissions of such
director occurring prior to such amendment or repeal.

    (a)  POWER TO INDEMNIFY IN ACTIONS, SUITS OR PROCEEDINGS OTHER THAN THOSE BY
OR IN THE RIGHT OF THE CORPORATION.  The corporation shall indemnify to the
fullest extent authorized or permitted by law (as now or hereafter in effect)
any person made, or threatened to be made, a party or witness to any
 
                                      II-1
<PAGE>
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 or she (or his or her
testator or intestate) is or was a director or officer of the corporation, or is
or was serving at the request of the corporation as a director or officer 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 such person in connection with
such action, suit or proceeding if he or she acted in good faith and in a manner
he or she 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 or her conduct was unlawful. The termination of
any action, suit or proceeding by judgment, order, settlement, conviction or
upon a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
or she 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
reasonable cause to believe that his or her conduct was unlawful.
 
    (b)  POWER TO INDEMNIFY IN ACTIONS, SUITS OR PROCEEDINGS BY OR IN THE RIGHT
OF THE CORPORATION. The corporation shall indemnify to the fullest extent
authorized or permitted by law (as now or hereafter in effect) any person made,
or threatened to be made a party or witness 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 he or she (or his or her
testator or intestate) is or was a director or officer of the corporation, or is
or was serving at the request of the corporation as a director or officer of
another corporation, partnership, joint venture, trust or other enterprise
against expenses (including attorneys' fees), and, if and to the extent
permitted by applicable law, judgments, penalties, and amounts to paid in
settlement, incurred by him or her in connection with defending, investigating,
preparing to defend, or being prepared to be a witness in, such action, suit,
proceeding or claim if such person acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the best interests of the
corporation; except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless (and only to the extent that) the Court of
Chancery or the court in which such action, suit, proceeding or claim 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 and amounts which
the Court of Chancery or such other court shall deem proper.
 
    (c)  AUTHORIZATION OF INDEMNIFICATION.
 
    (1) Any indemnification under Section 24 (unless ordered by a court) shall
be made by the corporation only as authorized in the specific case upon a
determination that indemnification of the director or officer is proper in the
circumstances because he has met the applicable standard of conduct set forth in
Section 24(a) or (b), as the case may be. Such determination shall be made (i)
by the Board of Directors by a majority vote of a quorum consisting of directors
who were not parties to such action, suit or proceeding, or (ii) if such a
quorum is not obtainable, or, even if obtainable, a quorum of disinterested
directors so directs, by independent legal counsel in a written opinion, or
(iii) by the stockholders; provided, however, that if a Change in Control (as
defined in Section 24(c)(3)) has occurred and the person seeking indemnification
so requests, such determination shall be made in a written opinion rendered by
independent legal counsel chosen by the person seeking indemnification and not
reasonably objected to by the Board of Directors (whose fees and expenses shall
be paid by the corporation). To the extent, however, that a director or officer
of the corporation has been successful on the merits or otherwise in defense of
any action, suit or proceeding described above, or in defense of any claim,
issue or matter therein, he or she shall be indemnified against expenses
(including attorneys' fees) incurred by him or her in connection therewith,
without the necessity of authorization in the specific case.
 
    (2) For purposes of the proviso to the second sentence of Section 24(c)(1),
"independent legal counsel" shall mean legal counsel other than an attorney, or
a firm having associated with it an attorney, who has been retained by or who
has performed services for the corporation or the person seeking indemnification
within the previous three years.
 
                                      II-2
<PAGE>
    (3) A "Change in Control" shall mean a change in control of the corporation
of a nature that would be required to be reported in response to Item 5(f) of
Schedule 14A of Regulation 14A promulgated under the Exchange Act, whether or
not the corporation is then subject to such reporting requirement; provided
that, without limitation, such a change in control shall be deemed to have
occurred if (i) any "person" (as such term is used in Section 13(d) and 14(d) of
the Exchange Act), other than a trustee or other fiduciary holding securities
under an employee benefit plan of the corporation or a corporation owned
directly or indirectly by the stockholders of the corporation in substantially
the same proportions as their ownership of stock of the corporation, is or
becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange
Act), directly or indirectly, of securities of the corporation representing
thirty percent (30%) or more of the total voting power represented by the
corporation's then outstanding shares of capital stock entitled to vote (the
"Voting Securities"), or (ii) during any period of two consecutive years,
individuals who at the beginning of such period constitute the Board of
Directors of the corporation and any new director whose election by the Board of
Directors or nomination for election by the corporation's stockholders who
approved by a vote of at least two-thirds ( 2/3) of the directors then still in
office who either were directors at the beginning of the period or whose
election or nomination for election was previously so approved, cease for any
reason to constitute a majority thereof, or (iii) the stockholders of the
corporation approve a merger or consolidation of the corporation with any other
corporation, other than a merger or consolidation which would result in any
Voting Securities of the corporation outstanding or by being converted into any
voting securities of the surviving entity) at least eighty percent (80%) of the
total voting power represented by all Voting Securities of the corporation or
such surviving entity outstanding immediately after such merger or
consolidation, or the stockholders of the corporation approve a plan of complete
liquidation of the corporation or an agreement for the sale or disposition by
the corporation of (in one transaction or a series of transactions) all or
substantially all of the corporation's assets.
 
    (d)  GOOD FAITH DEFINED.  For purposes of any determination under Section
24(c), a person shall be deemed to have acted in good faith and in a manner he
or she reasonably believed to be in or not opposed to the best interest of the
corporation, or, with respect to any criminal action or proceeding, to have had
no reasonable cause to believe his or her conduct was unlawful, if his or her
action is based on the records or on information supplied to him or her by the
officers of the corporation or another enterprise in the course of their duties,
or on the advice of legal counsel for the corporation or another enterprise or
on information or records given or reports made to the corporation or another
enterprise by an independent certified public accountant or by an appraiser or
other expert selected with reasonable care by the corporation or another
enterprise. The term "another enterprise" as used in this Section 24(d) shall
mean any other corporation or any partnership, joint venture, trust or other
enterprise of which such person is or was serving at the request of the
corporation as a director or officer. The provisions of this Section 24(d) shall
not be deemed to be exclusive or to limit in any way the circumstances in which
a person may be deemed to have met the applicable standard of conduct set forth
in Section 24(a) or (b), as the case may be.
 
    (e)  RIGHT TO INDEMNIFICATION UPON APPLICATION; PROCEDURE UPON APPLICATION,
ETC.  Except as otherwise provided in the proviso to Section 24(b):
 
        (1) Any indemnification under Section 24(a) or (b) shall be made no
    later than 30 days after receipt by the corporation of the written request
    of the director or officer or former director or officer unless a
    determination is made within said 30-day period in accordance with Section
    24(c) that such person has not met the applicable standard of conduct set
    forth in Sections 24(a) and (b).
 
        (2) The right to indemnification under Section 24(a) or (b) or advances
    under Section 24(f) shall be enforceable by the director or officer or
    former director or officer in any court of competent jurisdiction. The
    burden of proving that indemnification is not appropriate shall be on the
    corporation. Neither the absence of any prior determination that
    indemnification is proper in the circumstances, nor a prior determination
    that indemnification is not proper in the circumstances shall be a defense
    to the action or create a presumption that the director or officer or former
    director or officer has not met the applicable standard of conduct. The
    expenses (including attorneys' fees
 
                                      II-3
<PAGE>
    and expenses) incurred by the director or officer or former director or
    officer in connection with successfully establishing his or her right to
    indemnification, in whole or in part, in any such action (or in any action
    or claim brought by him to recover under any insurance policy or policies
    referred to in Section 24(i)) shall also be indemnified by the corporation.
 
        (3) If any person is entitled under any provision of this Section 24 to
    indemnification by the corporation for some or a portion of expenses,
    judgments, fines, penalties or amounts paid in settlement incurred by him or
    her, but not, however, for the total amount thereof, the corporation shall
    nevertheless indemnify such person for the portion of such expenses,
    judgments, fines, penalties and amounts to which he is entitled.
 
    (f)  EXPENSES PAYABLE IN ADVANCE.  Expenses incurred in defending or
investigating a threatened or pending action, suit or proceeding may be paid by
the corporation in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of the director or
officer to repay such amount if it shall ultimately be determined that he is or
she is not entitled to be indemnified by the corporation as authorized in this
Section 24; provided, however, that if he or she seeks to enforce his or her
rights in a court of competent jurisdiction pursuant to Section 24(e)(2), said
undertaking to repay shall not be applicable or enforceable unless and until
there is a final court determination that he or she is entitled to
indemnification as to which all rights of approval have been exhausted or have
expired.
 
    (g)  NON-EXCLUSIVITY OF INDEMNIFICATION AND ADVANCEMENT OF EXPENSES.  The
indemnification and advancement of expenses provided by or granted pursuant to
this Section 24 shall not be deemed exclusive of any other rights to which those
seeking indemnification or advancement of expenses may be entitled under any
by-law, agreement, contract, vote of stockholders or disinterested directors or
pursuant to the direction (howsoever embodied) of any court of competent
jurisdiction or otherwise, both as to action in his or her official capacity and
as to action in another capacity while holding such office, it being the policy
of the corporation that indemnification of the persons specified in Sections
24(a) and (b) shall or may, as the case may be, be made to the fullest extent
permitted by law. The provisions of this Section 24 shall not be deemed to
preclude the indemnification of any person who is not specified in Sections
24(a) and (b) but whom the corporation has the power or obligation to indemnify
under the provisions of the General Corporation Law of the State of Delaware, or
otherwise. The corporation may enter into written agreements, approved by a
majority of the Directors, which include all or any of the indemnity provisions
required or permitted by this Section 24.
 
    (h)  INSURANCE.  The corporation may purchase and maintain insurance on
behalf of any person who is or was a director or officer of the corporation, or
is or was serving at the request of the corporation as a director or officer of
another corporation, partnership, joint venture, trust or other enterprise
against any liability asserted against him or her and incurred by him or her in
any such capacity, or arising out of his status as such, whether or not the
corporation would have the power or the obligation to indemnify him or her
against such liability under the provisions of this Section 24.
 
    (i)  MEANING OF "CORPORATION" FOR PURPOSES OF SECTION 24.  For purposes of
this Section 24, references to "the corporation" shall include, in addition to
the resulting corporation, any constituent corporation (including any
constituent of a constituent) absorbed in a consolidation or merger which, if
its separate existence had continued, would have had power and authority to
indemnify its directors or officers so that any person who is or was a director
or officer of such constituent corporation, or is or was serving at the request
of such constituent corporation as a director or officer of another corporation,
partnership, joint venture, trust or other enterprise, shall stand in the same
position under the provisions of this Section 24 with respect to the resulting
or surviving corporation as he or she would have with respect to such
constituent corporation if its separate existence had continued.
 
    (j)  SURVIVAL OF INDEMNIFICATION AND ADVANCEMENT OF EXPENSES.  The
indemnification and advancement of expenses provided by, or granted pursuant to,
this Section shall, unless otherwise provided when authorized or ratified,
continue as to a person who has ceased to be a director or officer and shall
inure to the benefit of the heirs, executors and administrators of such a
person.
 
                                      II-4

    STATUTORY
 
    Generally, Section 145 of the General Corporation Law of the State of
Delaware authorizes Delaware corporations, under certain circumstances, to
indemnify their officers and directors against all expenses and liabilities
(including attorneys' fees) incurred by them as a result of any suit brought
against them in their capacity as a director or an officer, if they acted in
good faith and in a manner they reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, if they had no reasonable cause to believe their conduct was
unlawful. A director or officer may also be indemnified against expenses
incurred in connection with a suit by or in the right of the corporation if such
director or officer acted in good faith and in a manner reasonably believed to
be in or not opposed to the best interests of the corporation, except that no
indemnification may be made without court approval if such person was adjudged
liable to the corporation.
 
    UNDERWRITING AGREEMENT
 
    The Underwriting Agreement provides that the Underwriter shall indemnify
each director of the Company, each officer of the Company who signed this
Registration Statement, each person who controls the Company, and the Selling
Stockholders, for certain liabilities, including certain liabilities under the
Securities Act of 1933, as amended.

ITEM 17.  UNDERTAKINGS
 
    The undersigned registrant hereby undertakes:
 
        (1) For purposes of determining any liability under the Securities Act
    of 1933, each filing of the Company's annual report pursuant to section
    13(a) or section 15(d) of the Securities Exchange Act of 1934 that is
    incorporated by reference in the registration statement shall be deemed to
    be a new registration statement relating to the securities offering therein,
    and the offering of such securities at that time shall be deemed to be the
    initial BONA FIDE offering thereof.
 
        (2) To deliver or cause to be delivered with the prospectus, to each
    person to whom the prospectus is sent or given, the latest annual report to
    security holders that is incorporated by reference in the prospectus and
    furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule
    14c-3 under the Securities Exchange Act of 1934; and, where interim
    financial information required to be presented by Article 3 of Regulation
    S-X are not set forth in the prospectus, to deliver, or cause to be
    delivered to each person to whom the prospectus is sent or given, the latest
    quarterly report that is specifically incorporated by reference in the
    prospectus to provide such interim financial information.
 
                                      II-6
<PAGE>
        (3) 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.
 
        (4) 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.
 
        (5) For the purpose of determining any liability under the Securities
    Act of 1933, each post-effective 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.

    Pursuant to the requirements of the Securities Act of 1933, as amended, the
Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-3 and has duly caused this Amendment
No. 2 to the Registration Statement to be signed on its behalf by the
undersigned, thereunto duly authorized, in the City of Fort Lauderdale, State of
Florida, on the 17th day of September, 1996.
