Dear Stockholder:
    You  are cordially  invited to attend  a Special Meeting  of Stockholders of
Interim Services Inc. ("Interim Services"), which will be held at the offices of
Bryan Cave LLP, 245 Park Avenue, New  York, New York 10167-0034, at 10:00  a.m.,
local  time,  on Thursday,  May  23, 1996  (together  with all  adjournments and
postponements thereof, the "Interim Special Meeting").
 
    At the Interim Special  Meeting, you as holders  of shares of common  stock,
par value $0.01 per share, of Interim Services ("Interim Common Stock"), will be
asked  to consider and vote  upon a proposal to  approve the issuance of Interim
Common Stock pursuant to  the Agreement and Plan  of Merger, dated February  27,
1996  (the  "Merger Agreement"),  by and  among  Interim Services,  Delco Merger
Corp., a wholly-owned subsidiary of Interim Services ("Merger Sub"), and Brandon
Systems Corporation ("Brandon"). The Merger Agreement provides for the merger of
Merger Sub with and into Brandon  (the "Merger"), with Brandon as the  surviving
corporation  and  a  wholly-owned  subsidiary  of  Interim  Services.  Upon  the
effectiveness of the Merger, each outstanding  share of common stock, par  value
$0.10  per share, of Brandon ("Brandon Common Stock") will be converted into the
right to receive  0.88 shares (the  "Exchange Ratio") of  Interim Common  Stock,
subject  to certain anti-dilution adjustments.  However, no fractional shares of
Interim Common Stock will be  issued, and cash will be  paid in lieu thereof.  A
copy   of  the   Merger  Agreement  is   attached  to   the  accompanying  Proxy
Statement/Prospectus as Exhibit A.
 
    The Board  of  Directors of  Interim  Services has  carefully  reviewed  and
considered  the terms  and conditions of  the proposed Merger.  In addition, the
Board of  Directors  of  Interim  Services has  received  an  opinion  from  its
financial  advisor, Donaldson, Lufkin &  Jenrette Securities Corporation ("DLJ")
that, as of  April 23, 1996  the consideration  to be paid  by Interim  Services
pursuant  to the Merger Agreement is fair to the holders of Interim Common Stock
from a financial point of  view. A copy of the  fairness opinion is attached  to
the  accompanying Proxy Statement/Prospectus  as Exhibit C. We  urge you to read
the opinion in its entirety,  including certain assumptions and limitations  set
forth therein.
 
    THE  INTERIM BOARD BELIEVES  THAT THE MERGER  AGREEMENT AND THE TRANSACTIONS
CONTEMPLATED THEREBY ARE FAIR TO, AND IN THE BEST INTERESTS OF, INTERIM SERVICES
AND ITS STOCKHOLDERS.  ACCORDINGLY, THE INTERIM  BOARD HAS UNANIMOUSLY  APPROVED
THE  ISSUANCE  OF INTERIM  COMMON  STOCK PURSUANT  TO  THE MERGER  AGREEMENT AND
UNANIMOUSLY RECOMMENDS THAT ALL  INTERIM STOCKHOLDERS VOTE  FOR THE ISSUANCE  OF
INTERIM COMMON STOCK PURSUANT TO THE MERGER AGREEMENT.
 
    All  stockholders  are  invited to  attend  the Interim  Special  Meeting in
person. The affirmative  vote of  the holders  of a  majority of  the shares  of
Interim  Common Stock  voting at  the Interim  Special Meeting  is necessary for
approval of  the  issuance  of  Interim Common  Stock  pursuant  to  the  Merger
Agreement.
 
    The accompanying Proxy Statement/Prospectus constitutes a prospectus for the
Interim   Common  Stock  to  be  issued  in  connection  with  the  transactions
contemplated by the proposed Merger Agreement.  We urge you to carefully  review
and  consider the accompanying Notice of  Special Meeting of Stockholders, Proxy
Statement/Prospectus and Proxy, which contain information about Interim Services
and Brandon and describe the proposed Merger and certain related matters.
 
    IN ORDER THAT YOUR SHARES MAY BE REPRESENTED AT THE INTERIM SPECIAL MEETING,
YOU ARE URGED TO PROMPTLY COMPLETE, SIGN, DATE AND RETURN THE ACCOMPANYING PROXY
IN THE ENCLOSED POSTAGE PREPAID ENVELOPE, WHETHER OR NOT YOU PLAN TO ATTEND  THE
INTERIM  SPECIAL MEETING. Any stockholder returning  a blank executed Proxy will
be authorizing the  named proxies to  vote the  shares covered by  the Proxy  in
favor  of the  Merger Agreement.  If you attend  the Interim  Special Meeting in
person, you may, if you  wish, vote personally on all  matters on which you  are
entitled  to vote which are  brought before the Interim  Special Meeting even if
you have  previously  returned  your  Proxy. Your  prompt  cooperation  will  be
appreciated.
 
                                          Very truly yours,
 
                                          RAYMOND MARCY

Dear Stockholder:
 
    A Special Meeting of Stockholders of Brandon Systems Corporation ("Brandon")
will  be held on May 23, 1996 at 1:00 p.m. at the American Stock Exchange, Board

Merger  among  Brandon, Interim  Services  Inc. ("Interim  Services")  and Delco
Merger Corp.,  a wholly-owned  subsidiary of  Interim Services  ("Merger  Sub").
Pursuant to the Merger Agreement, Merger Sub will merge with Brandon, which will
become  a  wholly-owned  subsidiary  of Interim  Services,  and  stockholders of
Brandon will receive 0.88 shares of Interim Services common stock for each share
of  Brandon  common  stock  held  by  them,  subject  to  certain  anti-dilution
adjustments and with cash paid in lieu of fractional shares.
 
    Attached is a Notice of Special Meeting and Joint Proxy Statement/Prospectus
of  Brandon and Interim Services which also  is a prospectus of Interim Services
for the shares of  Interim common stock  to be issued in  the merger. The  Proxy
Statement/Prospectus describes the material features of the proposed merger, the
agreement  among the parties, the details  of the exchange and other information
about the parties to the merger.

meeting on the same day. The Interim Services Board of Directors has unanimously
approved  the  proposed  merger  and  has  recommended  that  Interim  Services'
stockholders vote  to approve  the  issuance of  Interim Services  common  stock
pursuant to the Merger Agreement.
 
    The  Board of Directors of Brandon has carefully reviewed and considered the
terms and conditions of  the proposed merger and  an opinion from its  financial
advisor,  Goldman, Sachs &  Co., to the effect  that, as of  April 23, 1996, the
Exchange Ratio  pursuant to  the Merger  Agreement  is fair  to the  holders  of
Brandon Common Stock.
 
    YOUR  BOARD OF  DIRECTORS HAS UNANIMOUSLY  APPROVED THE  PROPOSED MERGER AND
UNANIMOUSLY RECOMMENDS THAT YOU VOTE IN FAVOR OF IT.

the number of shares that you own. Whether or not you are planning to attend the
meeting,  it is important that your shares be represented. Please complete, sign

                           PROXY STATEMENT/PROSPECTUS
 
     SPECIAL MEETING OF STOCKHOLDERS             SPECIAL MEETING OF STOCKHOLDERS
        OF INTERIM SERVICES INC.                 OF BRANDON SYSTEMS CORPORATION
       TO BE HELD ON MAY 23, 1996                  TO BE HELD ON MAY 23, 1996
 
    This  Proxy Statement  and Prospectus (the  "Proxy Statement/Prospectus") is
being furnished  to  the  stockholders  of Interim  Services  Inc.,  a  Delaware
corporation  ("Interim Services"),  and to  the stockholders  of Brandon Systems
Corporation,  a  Delaware  corporation  ("Brandon"),  in  connection  with   the
solicitation  of proxies  by the  Boards of  Directors of  Interim Services (the
"Interim Board") and Brandon (the "Brandon  Board") for use at their  respective
special  meetings of  stockholders (individually, the  "Interim Special Meeting"
and the "Brandon Special  Meeting," and together,  the "Special Meetings").  The
Interim  Board and the  Brandon Board have  each fixed the  close of business on
April 23,  1996 (the  "Record Date")  as the  record date  for their  respective
Special Meetings.
 
    At the Brandon Special Meeting, holders of common stock, par value $0.10 per
share,  of Brandon ("Brandon Common Stock") will vote upon a proposal to approve
and adopt the Agreement and Plan of Merger, dated February 27, 1996 (the "Merger
Agreement"), by  and among  Interim  Services, Delco  Merger Corp.,  a  Delaware
corporation  and a wholly-owned  subsidiary of Interim  Services ("Merger Sub"),
and Brandon.  A  copy  of  the  Merger  Agreement  is  attached  to  this  Proxy
Statement/Prospectus as Exhibit A and incorporated herein by reference.
 
    At the Interim Special Meeting, holders of common stock, par value $0.01 per
share,  of  Interim  Services (the  "Interim  Common  Stock") will  vote  upon a
proposal to approve the issuance of Interim Common Stock pursuant to the  Merger
Agreement.
 
    SEE "RISK FACTORS" RELATING TO THE INTERIM COMMON STOCK BEGINNING ON PAGE 17
HEREOF.
 
    Pursuant  to the Merger Agreement,  Merger Sub will be  merged with and into
Brandon (the "Merger"),  with Brandon  as the corporation  surviving the  Merger
(the  "Surviving  Corporation")  and  as a  wholly-owned  subsidiary  of Interim
Services, and each outstanding share of  Brandon Common Stock will be  converted
into  the right to receive 0.88 shares  (the "Exchange Ratio") of Interim Common
Stock, subject to certain anti-dilution adjustments  and with cash paid in  lieu
of  fractional  shares.  However, upon  consummation  of the  Merger,  shares of
Brandon Common Stock which are held by Brandon as treasury shares, and shares of
Brandon Common Stock held by Interim Services, Merger Sub or any other direct or
indirect subsidiary  of  Interim  Services,  will  be  cancelled  and  thus  not
converted  into Interim Common Stock. SEE  "THE MERGER -- MERGER CONSIDERATION."
Additionally, upon consummation of the  Merger, each option to purchase  Brandon
Common  Stock (a  "Brandon Stock  Option") will be  converted into  an option to
purchase shares of Interim  Common Stock, rather than  shares of Brandon  Common
Stock,  at a  ratio of  0.88 shares of  Interim Common  Stock for  each share of
Brandon Common Stock covered  by the Brandon Stock  Options, subject to  certain
anti-dilution adjustments. SEE "THE MERGER -- TREATMENT OF OPTIONS."
 
    The  Merger is subject  to numerous conditions, among  them (i) approval and
adoption of the Merger  Agreement and the  Merger by the  affirmative vote of  a
majority  of the outstanding  shares of Brandon Common  Stock (which approval is
required under Delaware law),  (ii) receipt of an  opinion from Bryan Cave  LLP,
legal  counsel  to Interim  Services,  to the  effect  that, subject  to certain
assumptions, the Merger will constitute a tax-free reorganization under  Section
368(a)  of the  Internal Revenue  Code of 1986,  as amended  (the "Code"), (iii)
receipt of  reports  from Deloitte  &  Touche LLP,  independent  accountants  to
Interim  Services,  and Coopers  &  Lybrand L.L.P.,  independent  accountants to
Brandon, regarding qualification  of the Merger  as a pooling  of interests  for
accounting  purposes and  (iv) approval  of the  issuance of  the Interim Common
Stock pursuant to the Merger Agreement by the affirmative vote of a majority  of
the  shares of Interim Common Stock voting at the Interim Special Meeting (which
approval is  required under  the rules  of  The Nasdaq  Stock Market,  on  which
Interim  Common Stock is quoted). SEE "THE  MERGER -- CERTAIN FEDERAL INCOME TAX
CONSEQUENCES" and "CERTAIN PROVISIONS OF  THE MERGER AGREEMENT -- CONDITIONS  TO
THE CONSUMMATION OF THE MERGER."
 
    Ira  B. Brown and Myra  Brown, who together own  1,099,760 shares of Brandon
Common Stock, or 25.0%  of the outstanding  shares as of  the Record Date,  have
irrevocably  granted to  designees of Interim  Services the power  to vote their
shares of Brandon Common Stock for approval and adoption of the Merger Agreement
pursuant to an irrevocable proxy  which is attached as  Exhibit B to this  Proxy
Statement/Prospectus and is incorporated herein by reference. SEE "THE MERGER --
IRREVOCABLE  PROXY."  Additionally,  the  directors  and  executive  officers of
Brandon (other than the Browns) hold in
<PAGE>
the aggregate 104,555 shares of Brandon  Common Stock, or approximately 2.4%  of
the  outstanding shares as of the Record Date, and have indicated that they will
vote all of their shares  of Brandon Common Stock  for approval and adoption  of
the Merger Agreement.
 
    The  Interim Board has retained the services of Donaldson, Lufkin & Jenrette
Securities Corporation ("DLJ"), on the basis of DLJ's experience in transactions
similar to the Merger, to provide an opinion to the Interim Board concerning the
fairness of the consideration to be paid by Interim Services in the Merger  from

Interim  Board received the oral  opinion of DLJ that,  as of February 26, 1996,

holders of Interim Common Stock from a financial point of view. DLJ subsequently

confirming its oral opinion.  DLJ subsequently confirmed  its February 27,  1996
opinion by delivery of its written opinion dated as of April 23, 1996. A copy of
such  opinion is attached to this Proxy Statement/Prospectus as Exhibit C and is
incorporated herein by reference. HOLDERS OF  INTERIM COMMON STOCK ARE URGED  TO

THE MERGER
    FORM OF THE MERGER..........  At  the date  and time  the Merger  becomes effective (the
                                  "Effective Time"), Merger Sub will be merged with and into
                                  Brandon, with Brandon as  the surviving corporation and  a
                                  wholly-owned subsidiary of Interim Services.
    REASONS FOR THE MERGER......  INTERIM   SERVICES.  Numerous  factors   were  taken  into
                                  consideration by  Interim Services  in entering  into  the
                                  Merger   Agreement,  including,  without  limitation,  the
                                  personnel,  products,   operations,   prospects,   assets,
                                  obligations  and earnings of Brandon and Interim Services'
                                  judgments with respect to  the prospects for both  Interim
                                  Services   and   Brandon.  Interim   Services'  management
                                  believes that the addition  of Brandon's operation to  the
                                  IT unit of Interim Services offers a number of advantages,
                                  including  (i)  broad geographic  coverage of  its offices
                                  which complement current operations, (ii) achievement of a
                                  critical  mass  for  the  total  IT  operation,  including
                                  Brandon,  and  (iii) vertical  expansion  of the  scope of
                                  services which the IT unit  can offer. SEE "THE MERGER  --

                                  OF INTERIM SERVICES' BOARD OF DIRECTORS."
                                  BRANDON.  Numerous factors were taken into account by  the
                                  Brandon  Board in  approving the Merger  Agreement and the
                                  Merger, including the strategic  business benefits of  the
                                  Merger,  the  financial  benefits  of  the  Merger  to the
                                  Brandon   stockholders,    the   complementary    business
                                  philosophies  of Brandon and  Interim Services and various
                                  market factors. For a  detailed discussion of the  factors

    INTERESTS OF CERTAIN PERSONS
     IN THE MERGER..............  Certain  members of  Brandon's management  and the Brandon
                                  Board may be  deemed to  have interests in  the Merger  in
                                  addition  to  their interests  as stockholders  of Brandon
                                  generally,  including,  among  other  things,  accelerated
                                  vesting of certain Brandon Stock Options upon consummation
                                  of the Merger, provisions in the Merger Agreement relating
                                  to indemnification, and the continuation of employment and
                                  change  in control agreements. Interim Services expects to
                                  continue the employment  of Brandon's  officers after  the
                                  Merger  under the  terms and conditions  of the employment
                                  arrangements presently in effect  between Brandon and  its
                                  officers.  SEE "THE MERGER -- INTERESTS OF CERTAIN PERSONS
                                  IN THE MERGER."
    TREATMENT OF OPTIONS........  Upon consummation of the Merger, each outstanding  Brandon
                                  Stock  Option will be converted into an option to purchase
                                  shares of  Interim Common  Stock,  rather than  shares  of
                                  Brandon Common Stock, at a ratio of 0.88 shares of Interim
                                  Common  Stock  for  each  share  of  Brandon  Common Stock
                                  covered by the Brandon  Stock Options, subject to  certain
                                  anti-dilution  adjustments. The vesting of certain Brandon
                                  Stock Options will be accelerated by virtue of the  Merger
                                  constituting  a  change  in control  under  the applicable
                                  stock  option  plan.  SEE  "THE  MERGER  --  TREATMENT  OF

                                  Interim Services and who will, subject to the requirements

                                  Services' stockholders  to be  held in  1999. Such  person
                                  will be one of the directors of Brandon at the time of the

                                  termination  of the Merger  Agreement and Brandon entering

                                  Services a  termination fee  equal  to $1.5  million.  SEE
                                  "CERTAIN   PROVISIONS   OF   THE   MERGER   AGREEMENT   --
                                  TERMINATION; TERMINATION FEE."
    REGULATORY APPROVALS........  Consummation of  the  Merger  requires  notifications  to,
                                  and/or  approvals from,  certain governmental authorities,
                                  including  without  limitation,  notifications  under  the
                                  Hart-Scott-Rodino  Antitrust Improvements Act of 1976 (the
                                  "H-S-R Act") and the  rules promulgated thereunder by  the

    ACCOUNTING TREATMENT........  The  Merger  is expected  to  be accounted  for  using the
                                  pooling-of-interests  method  of  accounting.  Under   the
                                  Merger  Agreement,  it  is a  condition  precedent  to the
                                  obligation of  each of  Interim  Services and  Brandon  to
                                  consummate the Merger that each will have received reports
                                  from  Deloitte  & Touche  LLP, independent  accountants to
                                  Interim  Services,   and   Coopers   &   Lybrand   L.L.P.,
                                  independent accountants to Brandon, regarding
                                  qualification  of the Merger as a pooling of interests for
                                  accounting purposes.  In  this  regard,  Interim  Services
                                  expects  to receive an opinion  from Deloitte & Touche LLP
                                  to the effect that the Merger  will be accounted for as  a
                                  pooling  of  interests.  Brandon expects  to  receive from
                                  Coopers &  Lybrand  L.L.P. a  letter  to the  effect  that
                                  Coopers  & Lybrand L.L.P. concurs  with the conclusions of
                                  Brandon's management that no conditions exist with respect
                                  to Brandon which would preclude accounting for the  Merger
                                  as a pooling of interests. The pooling-of-interests method
                                  of  accounting is intended to present as a single interest
                                  two  or  more  common  stockholder  interests  which  were
                                  previously independent. The pooling-of-interests method of
                                  accounting  treats the combining  companies as having been
                                  merged  from  inception.   Consequently,  the   historical
                                  financial statements for periods prior to the consummation
                                  of the Merger will be restated as though the companies had
                                  been  combined  from the  beginning  of such  periods. SEE
                                  "CERTAIN PROVISIONS OF THE MERGER AGREEMENT --  CONDITIONS
                                  TO  CONSUMMATION  OF  THE  MERGER,"  "UNAUDITED  PRO FORMA
                                  COMBINED CONDENSED FINANCIAL INFORMATION" AND "THE  MERGER
                                  -- ACCOUNTING TREATMENT."
    CERTAIN FEDERAL INCOME TAX
     CONSEQUENCES...............  The  Merger is intended to qualify, for federal income tax
                                  purposes, as a "tax-free"  reorganization so that no  gain
                                  or  loss will be recognized by Brandon stockholders on the
                                  exchange of their Brandon Common Stock for Interim  Common
                                  Stock, except in

                                  Although no  ruling will  be requested  from the  Internal
                                  Revenue  Service ("IRS") regarding the tax consequences of
                                  the Merger, under the Merger  Agreement it is a  condition
                                  to  the obligation of each of Brandon and Interim Services
                                  to consummate the Merger that they each receive an opinion
                                  from Bryan Cave LLP, legal counsel to Interim Services, to
                                  the  effect  that,  if   the  Merger  is  consummated   in
                                  accordance  with the  terms of  the Merger  Agreement, for
                                  federal income tax purposes, the Merger will constitute  a
                                  reorganization within the meaning of Section 368(a) of the
                                  Code.  For  a  more complete  description  of  the federal

                                  stockholders  are  entitled   to  dissenter's  rights   of

                          INTERIM SERVICES AND BRANDON
                 NOTES TO SELECTED AND SUPPLEMENTARY HISTORICAL
                          AND PRO FORMA FINANCIAL DATA
                 (AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
(1) Interim Services made  certain significant acquisitions  in 1995 which  were
    accounted  for under  the purchase method  of accounting.  The unaudited pro
    forma consolidated statement  of income and  sales data give  effect to  the
    acquisitions as though they occurred at the beginning of 1995 with pro forma
    adjustments  to give effect to amortization of goodwill, interest expense on
    additional borrowings used to fund the acquisitions, and other  adjustments,
    together  with income tax effects. SEE NOTES TO UNAUDITED PRO FORMA COMBINED
    CONDENSED FINANCIAL INFORMATION.
 
(2) Prior  to its  January 27,  1994 initial  public offering  ("IPO"),  Interim
    Services'  working capital  and acquisition  financing were  provided by its
    former parent,  H&R Block,  Inc. ("Block").  Effective September  25,  1993,
    Block  formalized  its financing  arrangement by  (i) providing  a revolving
    credit facility in the amount of  $20,000 to fund operating requirements  of
    Interim  Services; (ii)  converting $30,000 of  intercompany indebtedness on
    such date to a term loan, and  (iii) contributing $51,289 to the capital  of
    Interim  Services. The  consolidated statement  of income  and balance sheet
    data for the three years ended December 24, 1993 (unaudited) give effect  to
    this arrangement as if it occurred at the beginning of the respective years.
    Interest  expense has been computed at 6%  and income taxes at the statutory
    rate.
 
(3) Per share data for Brandon in  1991 has been retroactively restated for  the
    five-for-four stock split occurring in 1992.
 
(4)  Pro forma cash  dividends per share  amounts represent Brandon's historical
    cash dividends  per share  amounts after  converting each  share of  Brandon
    Common  Stock into 0.88 shares of Interim Common Stock. Interim Services has
    not paid, and does  not expect to  pay in the  foreseeable future, any  cash
    dividends on Interim Common Stock.
 
(5)  The Supplementary Historical Financial Data is unaudited and represents the
    branch and  licensee revenues  of  Interim Services  and  the sales  of  its
    franchises  from  which  Interim Services'  franchise  royalty  revenues are
    earned. Sales data for Interim Services' franchised offices are derived from
    unaudited reports provided by  its franchisees. The Supplementary  Unaudited
    Pro  Forma Financial  Data includes  the Supplementary  Unaudited Historical
    Financial Data of Interim Services and the historical revenues of Brandon.

                                  RISK FACTORS
 
    IF   THE  MERGER  IS  CONSUMMATED,   STOCKHOLDERS  OF  BRANDON  WILL  BECOME
STOCKHOLDERS OF INTERIM SERVICES. IN ADDITION  TO THE OTHER INFORMATION IN  THIS
PROXY  STATEMENT/PROSPECTUS,  THE  FOLLOWING  INFORMATION  RELATING  TO  INTERIM
SERVICES SHOULD BE CONSIDERED CAREFULLY.
 
COMPETITIVE MARKET
 
    The flexible  staffing industry  is competitive,  with limited  barriers  to
entry.  Interim Services competes  in national, regional  and local markets with
full service agencies and with specialized temporary services agencies and  home
care  providers.  The majority  of  competitors are  significantly  smaller than
Interim Services.  However,  several  competitors  have  greater  marketing  and
financial  resources than  those of  Interim Services.  Interim Services expects
that the level of competition will remain high in the future.
 
ABILITY TO CONTINUE AND MANAGE COMPANY GROWTH
 
    Interim Services has experienced significant growth in the past, principally
through the acquisition of existing businesses  and the opening of new  offices,
as well as through licensing and franchising. There can be no assurance that, in
the  future, Interim Services will  continue to be able  to establish and expand
its market  presence,  or  to  successfully enter  other  markets  or  integrate
acquired  businesses into  its operations.  The ability  of Interim  Services to
continue and  manage  its growth  will  depend on  a  number of  other  factors,
including  existing and emerging competition and  the availability of capital to
support such growth as well as Interim Services' ability to maintain margins  in
the   face  of  pricing  pressures,  to  manage  costs  in  changing  regulatory
environments  and  to   recruit  and  train   additional  qualified   personnel.
Additionally,  there can be no assurance  that Interim Services will continue to
identify suitable acquisition candidates or  complete the acquisitions on  terms
favorable to Interim Services.
 
RELIANCE ON KEY PERSONNEL
 
    Interim  Services  is highly  dependent on  its  management. The  success of
Interim Services depends 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 Interim Services' operations.
 
INFORMATION TECHNOLOGY TRENDS
 
    The size and 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 increases, and  as
the  general  corporate  trend  towards  downsizing  continues,  businesses  are
increasingly turning to specialized, outside technical personnel to staff  their
IT  operations. The success of Interim Services  in the IT area depends in large
part on  its ability  to keep  pace  with existing  technology and  predict  new
technological  changes and  advancements. Although Interim  Services attempts to
follow industry  trends closely  and anticipate  new changes,  there can  be  no
assurance  that Interim  Services will  be able  to anticipate  and successfully
respond to new technological advancements in the future.
 
EFFECT OF FLUCTUATIONS IN THE GENERAL ECONOMY
 
    Demand for commercial  staffing services  is significantly  affected by  the
general  level  of  economic activity  in  the country.  When  economic activity
increases, flexible staff are often added before full-time employees are  hired.
Similarly,  as economic  activity slows,  many companies  reduce their  usage of
flexible staff  before  undertaking  layoffs  of  their  regular  employees.  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.  Traditionally, demand for  the health care  services of Interim Services
has not been directly affected by the overall state of the economy. There can be
no assurance, however, that Interim Services' HealthCare Division will  continue
to be unaffected by changes in the overall economy.
 
DEPENDENCE ON AVAILABILITY OF QUALIFIED PERSONNEL
 
    Interim Services depends upon its ability to attract qualified personnel who
possess the skills and experience necessary to meet the staffing requirements of
its  clients. Interim Services must continually evaluate and upgrade its base of
available   qualified    personnel   to    keep   pace    with   the    changing
 
                                       17
<PAGE>
client  needs and emerging technologies. Competition for individuals with proven
professional skills, particularly home  health care providers, IT  professionals
and  other  skilled  employees,  is  intense. There  can  be  no  assurance that
qualified personnel  will  continue  to  be available  to  Interim  Services  in
sufficient numbers in the future.
 
GOVERNMENTAL REGULATION
 
    A  number of states  have adopted laws that  regulate companies that provide
health care services.  In many of  the states with  such laws, Interim  Services
need  only be  licensed. In  approximately 23  states, 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.
 
LIABILITY/INDUSTRY RISKS
 
    Flexible  staffing providers  employ and place  people in the  work place of
other businesses. Attendant risks  of such activity  include possible claims  of
discrimination   and  harassment,  employment  of  illegal  aliens,  errors  and
omissions by Interim Services'  flexible staff, particularly  for the action  of
temporary   professionals   (e.g.,   accountants  and   attorneys),   misuse  or
misappropriation of client  funds or proprietary  information and other  similar
claims.  Such claims may result in  negative publicity, injunctive relief or the
payment of monetary damages or fines by Interim Services. While Interim Services
maintains insurance policies  covering general liability,  errors and  omissions
and  employee theft, there can be no assurance that such insurance coverage will
be adequate in scope or amount to cover any such liability.
 
FRANCHISING RISKS
 
    For fiscal year 1995, 46.8% of Interim Services' sales (representing 3.1% of
revenues) were derived  from franchised  operations. Moreover,  the largest  ten
franchisees  (based on  sales volume)  accounted for 21%  of the  total sales of
Interim Services in fiscal 1995. Franchisees  may leave the franchise system  at
the  end  of  the  term of  their  franchise  agreements and  have  in  the past
terminated their franchise agreements before the end of the franchise  agreement
term. While Interim Services' agreements contain non-competition covenants, such
covenants may not prevent the loss of sales.
 
UNEMPLOYMENT INSURANCE; WORKERS' COMPENSATION
 
    Interim  Services  is required  to pay  unemployment insurance  premiums and
workers' compensation  costs  for  its flexible  staff.  Unemployment  insurance
premiums have continued to increase generally 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,  Interim
Services'  health-related costs  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.  There can  be no
assurance that Interim Services will be able to increase the fees charged to its
clients  to  absorb  the  increased  costs  related  to  workers'  compensation,
unemployment  insurance, or employer-paid health insurance benefits that must be
extended to flexible staff.
 
ANTI-TAKEOVER CONSIDERATIONS
 
    Interim Services'  Restated Certificate  of Incorporation  and the  Delaware
General Corporation Law contain certain provisions that could have the effect of
making it more difficult for a party to acquire, or of discouraging a party from
attempting  to  acquire  control of  Interim  Services without  approval  of the
Interim Board. In addition, the Interim Board has adopted a stockholder's rights
plan. The  foregoing may  discourage tender  offers or  other bids  for  Interim
Common  Stock at a premium over the market price of the Interim Common Stock. In
addition, the  requirement that  a  change of  control  of Interim  Services  be
approved by the Public Health Council of the New York State Department of Public
Health may have a similar effect.

RECORD DATE; SHARES ENTITLED TO VOTE; QUORUM

on April  23, 1996  as the  Record Date  for the  determination of  the  Interim

authorized  shares of Brandon Common Stock of which 4,399,146 shares were issued

respective Special Meetings.
 
    The  presence, in person  or by proxy, of  the holders of  a majority of the
outstanding shares of Interim Common Stock or Brandon Common Stock, as the  case
may  be, entitled to vote at the  Interim Special Meeting or the Brandon Special
Meeting, as  the case  may  be, is  necessary to  constitute  a quorum  for  the
transaction  of business at such Special Meeting. If a quorum is not obtained at
either Special Meeting, such Special Meeting may be adjourned for the purpose of
obtaining additional proxies  or votes  or for any  other purpose,  and, at  any
subsequent reconvening of such Special Meeting, all proxies will be voted in the
same  manner as such proxies would have  been voted at the original convening of
the meeting  (except for  any proxies  which have  theretofore effectively  been
revoked or withdrawn), notwithstanding that they may have been effectively voted
on the same or any other matter at a previous meeting.
 
VOTING OF PROXIES
 
    Each  holder of  Interim Common  Stock and  Brandon Common  Stock as  of the
Record Date will be entitled to vote at their respective Special Meeting.  Votes

properly  submitting  to Interim  Services or  Brandon,  as appropriate,  a duly
executed proxy bearing a later date, or (iii) attending the appropriate  Special
Meeting  and voting in person. Attendance at the Special Meeting will not in and
of itself revoke a proxy. However, a stockholder can revoke a proxy by attending
the Special Meeting and notifying the secretary of the Special Meeting, prior to
the vote at  the Special  Meeting, that  such holder  would like  to revoke  the
proxy.  All written notices of revocation  and other communications with respect

                       INFORMATION ABOUT INTERIM SERVICES
 
BUSINESS
 
    BACKGROUND
 
    Interim  Services  has evolved  significantly  since its  founding  in 1946.
Interim Services was originally formed to provide temporary industrial and light
industrial staffing services. Nursing and home care staffing services were first
provided in 1966,  and Interim  Services has since  expanded to  provide a  wide
range of flexible staffing services.
 
    On  August  16, 1978,  Interim  Services, 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,
secretarial,  light  industrial and  health  care personnel  through  178 branch
offices in 20  states and three  Canadian provinces. The  businesses of  Interim
Services  and ISC were combined on December  31, 1991. On June 15, 1992, Interim
Services changed its name to "Interim Services Inc."
 
    On January 27, 1994, Interim Services  completed an initial offering of  its
common  stock to  the public at  $20 per  share ("IPO"). Since  its IPO, Interim
Services has acquired ten flexible  staffing companies including five  companies
acquired  in fiscal year 1994  and five companies acquired  in fiscal year 1995.
The five companies  acquired in  1994 had pro  forma combined  revenue of  $42.0
million  (assuming full year  results). The five companies  acquired in 1995 had
pro forma combined revenue of $119.0 million (assuming full year results).
 
    Interim Services is a Delaware corporation whose corporate headquarters  are
located  at  2050 Spectrum  Boulevard, Fort  Lauderdale, Florida  33309. Interim
Services' telephone number is (954) 938-7600.
 
    BUSINESS OVERVIEW
 
    Interim Services provides customized staffing solutions on a national  basis
including  flexible staffing, home health  care, full-time placement, consulting
and  other  value-added  services   to  businesses,  professional  and   service
organizations, governmental agencies, health care facilities and individuals. As
of December 29, 1995, Interim Services operated through a network of 908 offices
in 48 states, the District of Columbia, Puerto Rico, Canada, The Netherlands and
the United Kingdom.
 
    Interim  Services operates  through two divisions:  the Commercial Division,
which generated 53%  of system-wide  sales, and the  HealthCare Division,  which
generated  47%  of  system-wide  sales  in  1995.  Interim  Services' management
believes that,  based  on system-wide  sales,  Interim Services  is  the  fourth
largest provider of commercial staffing services and the second largest provider
of   temporary  health  care  personnel  in  North  America.  Interim  Services'
management also believes that Interim Services offers the broadest selection  of
staffing services available in the flexible staffing industry.
 
                                       21
<PAGE>
    The Commercial Division serves client requirements for traditional temporary
clerical  and light industrial skills as  well as increasingly filling needs for
specialty professional skills such as  IT, legal and accounting. The  HealthCare
Division  provides  a  broad range  of  personnel including  home  health aides,
nurses, home companions, therapists and  physicians. In 1995, approximately  80%
of  the HealthCare Division's services (based  on revenues) were provided in the
home environment, the fastest growing portion of the health care industry.
 
    Interim Services' goal  is to become  the leading full  service provider  of
flexible  staffing services to  commercial and health  care organizations and to
individuals throughout  North  America. Interim  Services'  strategy  emphasizes
expansion  of the number of locations and  markets in which services are offered
as well  as  the breadth  of  services provided.  Interim  Services'  management
believes  that  an  important  component of  Interim  Services'  success  is its
decentralized entrepreneurial  environment operating  under an  umbrella of  the
common "INTERIM" brand identity and a collective vision of client service.
 
GROWTH STRATEGY
 
    Interim  Services'  acquisition  strategy  focuses  on  those  markets where
Interim Services lacks sufficient offices  and those specialized service  niches
where Interim Services believes opportunities for growth exist. Interim Services
intends to focus on expansion through licenses and new franchises in the smaller
and  mid-size  markets where  having independent  local  management is  often an
advantage. In larger  markets, where  it can  centralize its  regional and  area
management  and other administrative functions to  support a cluster of offices,
Interim Services intends to expand company-owned branches. Management has  found
that Interim Services' strong reputation and decentralized management style have
assisted  its efforts  to acquire  small, independent  offices that  are seeking
alliances  as  size  and  national  presence  increasingly  become  a  strategic
advantage.
 
INDUSTRY OVERVIEW
 
    COMMERCIAL FLEXIBLE STAFFING INDUSTRY
 
    Revenues  for the  flexible staffing  industry were  expected to  exceed $60
billion in 1995 according to the  Staffing Industry Report, a staffing  services
industry  publication. Further,  temporary help,  the largest  staffing services
sector, was estimated to have 1995 revenues of approximately $41 billion and has
grown at an average annual rate of approximately 17.5% over the past four years.
According to the Bureau of Labor  Statistics, the flexible staffing industry  is
the  seventh  fastest growing  industry in  the United  States with  a projected
growth rate of 58.1% from 1994 to 2005.
 
    The use of temporary personnel has become widely accepted as a valuable tool
for managing  personnel costs,  supplementing permanent  workforces and  meeting
specialized  or fluctuating  employment requirements. Effective  use of flexible
staff enables  businesses to  staff their  organizations with  a core  level  of
full-time  personnel by supplementing their full-time work force only as needed.
Organizations have also begun using  flexible staffing to reduce  administrative
overhead  by outsourcing  operations that  are not  part of  their core business
functions. Outsourcing not  only shifts  cost from  fixed to  variable but  also
benefits  the client by providing the efficiencies of professional management of
their workforce. An  ancillary benefit,  particularly for  small businesses,  is
that  outsourcing shifts employment costs and risks (e.g., workers' compensation
and unemployment insurance) to the flexible staffing companies, which can spread
the costs and risks over a larger pool of employees.
 
    The range of flexible staffing services available has expanded substantially
since the early days of the industry. Over the last decade, the increased use of
technology has led to a dramatic  rise in demand for technical project  support,
software  development  and  other computer-related  services.  Corporations have
outsourced many  of these  departments and/or  have utilized  flexible  staffing
firms in an attempt to meet the increased demand for computer-skilled personnel.
In  addition, changing attitudes  towards workforce management  have propelled a
dramatic increase in flexible professional personnel,
 
                                       22
<PAGE>
such as  accountants,  paralegals,  attorneys and  computer  programmers.  These
specialty and professional sectors of the flexible staffing industry are growing
considerably faster than the industry as a whole.
 
    The  flexible  staffing  industry  is  highly  fragmented  and  is currently
experiencing a trend towards consolidation.  This trend reflects the  increasing
demand  by  large  companies for  centralized  staffing services  and  growth of
national and regional  accounts resulting  from the  centralization of  staffing
decisions which has increased the importance of staffing companies being able to
offer  a wide range of  services over a broad  geographic area. Smaller staffing
companies that are  unable to provide  national services and  that have  limited
capital  and  management  resources  are increasingly  finding  it  difficult to
compete.
 
    HEALTH CARE STAFFING INDUSTRY
 
    Health care staffing services can be divided into two service sectors  based
on  the  location of  care delivery.  The health  care staffing  sector provides
general and specialized health care personnel for hospitals, nursing homes, HMOs
and other health care facilities. The home care sector consists of providing the
same health care  skills, as  well as  companionship, in  the home  environment.
Historically,  home care  has been  one of  the fastest  growing sectors  of the
health care industry, and has grown at an estimated average annual rate of 16.4%
since 1988 according to the Bureau of Labor Statistics.
 
    Contributing to  the growth  of home  health care  is national  pressure  to
reduce  health care costs.  Studies indicate that  the cost of  home health 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. Interim Services
believes that most  patients, when given  a choice,  prefer to be  cared for  at
home.
 
    Size  and national presence  are becoming increasingly  important factors in
the home health care industry. Private  insurers use case managers and  contract
managers  who purchase home  care services in  volume, while private individuals
rely on physicians, HMOs, hospital discharge planners and insurers for referrals
to  home  care   providers.  As  national   and  regional  payor   organizations
increasingly  dominate health care  purchases, the ability  to provide home care
services nationally is becoming a competitive advantage. A national distribution
network is important to obtaining business from these organizations which  often
prefer to have one or two suppliers who can provide health care personnel over a
broad geographic region.
 
DESCRIPTION OF INTERIM SERVICES CAPITAL STOCK
 
    The  authorized  capital stock  of Interim  Services consists  of 27,500,000
shares of which 25,000,000 shares are Interim Common Stock and 2,500,000  shares
are  Interim Preferred Stock. As of April 23, 1996, there were 11,540,109 issued
and outstanding shares  of Interim Common  Stock and no  issued and  outstanding
shares of Interim Preferred Stock.
 
    COMMON STOCK
 
    Generally,  the vote of the holders of a  majority of all shares of stock of
Interim Services voting (whether in person or by proxy) on a matter will  decide
such   matter,  unless  express  provisions  of  law  or  the  Interim  Services
Certificate of Incorporation  require a  different vote. All  shares of  Interim
Common  Stock are deemed to be voting stock of Interim Services, and all holders
thereof are entitled  to one  vote for  each share  of stock  standing in  their
names. Holders of Interim Common Stock have no pre-emptive rights to purchase or
subscribe for any stock or other securities of Interim Services. The outstanding
Interim  Common  Stock is,  and the  Interim Common  Stock to  be issued  in the
Merger, when issued and delivered will  be, fully paid and non-assessable.  Each
holder  of Interim  Common Stock  on the applicable  record date  is entitled to
receive such dividends as may  be declared by the  Interim Board at any  meeting
out  of  funds legally  available therefor.  No  dividend or  other distribution
 
                                       23
<PAGE>
with respect to  Interim Common Stock  has ever been  paid by Interim  Services,
other  than in  connection with  the stockholders  rights plan  discussed below.
Interim Services  currently  intends to  retain  any  earnings for  use  in  its
business  and does  not anticipate paying  any cash dividends  in the forseeable
future.
 
    Interim Services 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  Interim Services 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 Interim Common Stock outstanding on April 1, 1994 and with respect
to  shares  of  Interim  Common  Stock  issued  after  such  date,  Rights  will
automatically  attach to them  after their issuance. Under  the plan, holders of
each Right may purchase from Interim Services one one-hundredth of a share of  a
new  class of Interim Services' 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 when a person or group of persons acquires 15% or more
of the outstanding shares of Interim Common Stock without prior written approval
of  the Interim Board  ("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 Interim
Common Stock having  a market value  equal to  twice the exercise  price of  the
Right.  Following  an  Unapproved  Stock  Acquisition,  if  Interim  Services is
involved in a  merger, or 50%  or more  of Interim Services'  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 Interim Common
Stock, the Interim Board may  exchange all or part  of the then outstanding  and
exercisable Rights for Interim Common Stock at an exchange ratio of one share of
Interim  Common Stock per Right. Upon any such exchange, the right of any holder
to exercise a  Right terminates.  Interim Services 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  Interim Board. Until  a Right  is exercised, the
holder thereof, as  such, has no  rights as a  stockholder of Interim  Services,
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 Interim  Board has  the authority  to issue  up to  2,500,000 shares  of
preferred  stock,  par  value  $.01 per  share,  of  Interim  Services ("Interim
Preferred Stock") 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  Interim Preferred  Stock are  outstanding. Any  shares of  Interim
Preferred  Stock so  authorized and  issued may  have priority  over the Interim
Common Stock with respect to dividend and liquidation rights.
 
    CERTAIN EFFECTS OF AUTHORIZED BUT UNISSUED STOCK
 
    Interim Services' 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 Interim
Preferred Stock and Interim Common Stock may  be to enable the Interim Board  to
issue shares to persons friendly to
 
                                       24
<PAGE>
current management which could render more difficult or discourage an attempt to
obtain  control of Interim  Services by means  of a merger,  tender offer, proxy
contest or otherwise, and  thereby protect the  continuity of Interim  Services'
management.   Issuance  of   Interim  Preferred   Stock  might,   under  certain
circumstances, deter the acquisition of Interim Services or its securities by  a
person concerned about the terms or effect of such Interim Preferred Stock.

    Merger  Sub, a wholly-owned subsidiary of Interim Services, was incorporated
on February 20, 1996 by Interim Services solely for the purpose of effecting the
Merger. Merger Sub is  a Delaware corporation  whose corporate headquarters  are

BUSINESS
 
    Founded  in  1968,  Brandon  is  a  nationwide  outsourcing  service company
supplying technical and professional computer staff specializing in IT services.

    BRANDON INSOURCING-TM- SERVICES
 
    Brandon  provides a unique type of  outsourcing service to its clients under
the name of BRANDON INSOURCING-TM-. Unlike traditional outsourcing arrangements,
where the  service  provider takes  full  control of  a  customer's  information
systems  facility,  under  a  typical  BRANDON  INSOURCING-TM-  arrangement  the
customer maintains complete  strategic control,  and is  relieved of  technology
staffing  and performance issues which might tend to detract customer management
from focusing on its core business. BRANDON INSOURCING-TM- takes  responsibility
for  the day-to-day performance of  the customer's information systems facility,
including  the  functions  of  staffing,  day-to-day  supervision,  and  meeting
pre-determined  service  levels.  Brandon believes  that  BRANDON INSOURCING-TM-
engenders a partnering  relationship, providing customers  with the  traditional
savings  of outsourcing,  yet enabling  customers to  preserve strategic control
over  their  information   systems  and  data.   During  fiscal  1995,   BRANDON
INSOURCING-TM- contracts accounted for approximately 13% of Brandon's revenues.

                                   THE MERGER
 
GENERAL
 
    The discussion  in this  Proxy Statement/Prospectus  of the  Merger and  the
description  of the principal terms  of the Merger Agreement  are subject to and
qualified in their  entirety by  reference to the  Merger Agreement,  a copy  of
which   is  attached  to  this  Proxy  Statement/Prospectus  as  Exhibit  A  and
incorporated herein by reference.
 
BACKGROUND OF BRANDON'S ENTRY INTO THE MERGER AGREEMENT
 
    Historically, Brandon has sought to expand its operations and diversify  the
fields  of  expertise in  which it  provides IT  flexible staffing  solutions to
businesses. Brandon has successfully fostered internal expansion by opening  new
branches   (including  six  new  branch  offices  opened  in  various  locations
throughout the United States during calendar 1995, which brought the total to 30
branches) and by expanding its range of services to include additional  staffing
needs such as outsourcing and technical training.
 
    In  the view of Brandon management, expansion and diversification has become
increasingly important  in light  of the  trend in  recent years  for  corporate
clients to move toward meeting many of their supplemental staffing needs through
either one provider or a limited number of providers. This trend appears to be a
factor  in industry consolidation, with many  staffing providers growing in size
and scope  in  order to  compete  effectively  as primary  providers  for  their
clients.
 
    In  November  1995,  in view  of  this  background and  prompted  by another
staffing provider's  expression  of  interest in  a  business  combination,  the
Brandon  Board undertook to analyze the  range of strategies which Brandon might
adopt, including  continued  internal  growth, growth  through  acquisitions  of
smaller  businesses, or pursuit  of a business  combination with another entity.
From November 1995 through February 1996, through a series of more than a  dozen
Board  and Special Committee  meetings, the Brandon  Board examined and analyzed
the merger opportunities and  other strategic options  available to Brandon.  To
assist  with this process,  the Brandon Board  retained Goldman Sachs  to act as
Brandon's financial advisor. The  Board also sought and  received the advice  of
Brandon's management team and its legal and accounting professionals.
 
    With  the assistance of  its advisors, the Brandon  Board considered some of
the advantages which  could be  derived from a  business combination,  including
enhanced ability to make subsequent acquisitions, greater stockholder liquidity,
increased   market  recognition,  additional  product  offerings  and  potential
efficiencies  and  economies   of  scale.  The   Board  also  reviewed   Brandon
management's  internal business plan and the merger premiums then being obtained
in other industry  transactions, and considered  the possibility that  Brandon's
stockholders  might  receive  more  value through  a  merger  than  with Brandon
remaining an independent institution.
 
    Beginning in early  December 1995, at  the direction of  the Brandon  Board,
Goldman  Sachs initiated discussions  with a number of  potential partners for a
strategic combination  with Brandon,  some of  whom had  informally expressed  a
possible  interest in  such an alliance  prior to November  1995. Entities which
expressed interest in a possible alliance and signed a confidentiality agreement
were provided with a package of confidential information about Brandon. Over the
course of its engagement, Goldman Sachs contacted 19 entities which it, with the
assistance of  Brandon  management,  had  identified to  the  Brandon  Board  as
possible  partners. A number of these  entities requested and received a package
of confidential information about Brandon,  and initially expressed interest  in
pursuing transactions at nominal values to Brandon stockholders ranging from $27
to  $32  per Brandon  share. One  entity preliminarily  indicated that  it might
assign a value as high as $40-45 per
 
                                       27
<PAGE>
Brandon share  in  a  business  combination, but  also  indicated  that  it  was
precluded  from making any binding commitment until at least November 1996. That
entity never submitted a firm proposal, nor did it further refine its  tentative
price  estimate. Because  these expressions  of interest  generally contemplated
stock-for-stock rather  than  cash mergers,  the  actual value  which  would  be
realized  by Brandon  stockholders over time  could vary  significantly from the
value indicated by the entity expressing  interest due to pre- and  post-closing
fluctuations in the stock price of that entity.
 
    On  behalf of Brandon, and  at times with the  direct involvement of various
Brandon management and non-management directors, Goldman Sachs held  discussions
with  various interested parties. Brandon's management, its advisors and certain
of its  directors performed  due diligence  on, and  conducted management  group
meetings with, certain of the interested parties, including Interim Services.
 
    With  the advice  of its outside  legal and financial  advisors, the Brandon
Board sought to consider all possible courses of action, including remaining  an
independent  entity. While not  committing itself to  a particular strategy, the
Brandon Board, through Goldman Sachs, solicited firm and unconditional proposals
in an effort to arrive at a  proposal for a strategic business combination  upon
terms  and conditions that  the Brandon Board  believed were fair  to and in the
best  interests  of  Brandon's  stockholders.  Brandon,  through  its  financial
advisors   and  management   team,  negotiated   to  obtain   increases  in  the
consideration proposed by  those potential business  combination partners  which
had  expressed current interest in a transaction  at values in the higher end of
the range  covered by  the expressions  of  interest. On  February 18,  1996,  a
Special Committee of the Board, which was composed of Messrs. Elbaum (Chairman),
DeGhetto  and Tse,  was given  the responsibility,  through Brandon's  legal and
financial advisors, of serving  as an interface on  behalf of the Brandon  Board
with  interested  parties,  and  making recommendations  to  the  full  Board of
Directors on  a course  of action.  During  the latter  part of  February  1996,
Interim  Services  offered to  enter into  the  transaction contemplated  by the
Merger Agreement, at the consideration and on the terms and conditions specified
therein.
 
    These matters  were  all addressed  by  the Brandon  Board  in a  series  of
meetings,  culminating in a meeting  on February 26, 1996.  During the course of
those meetings, the Brandon Board considered,  among other things: the value  to
Brandon stockholders of the Interim Common Stock which they would receive in the
Merger,  the terms and  conditions proposed by  Interim Services, the background
and status  of Brandon's  contacts  with Interim  Services and  other  potential
business  combination partners, the financial condition and prospects of Interim
Services, the historical trends and future prospects for the business of Brandon
on a stand-alone basis, Brandon's strategic options and Goldman Sachs' advice on
each of these matters. In deciding to approve the Merger Agreement, the  Brandon
Board  also considered  the expressions of  interest which it  had received from
other entities, including an  expression of interest at  a higher nominal  value
than  that contemplated  by the  Merger. Brandon  had held  discussions with the
entity whose expression of interest in early November 1995 prompted the  process
in  an effort  to obtain  that entity's best  and final  proposal. Subsequent to
having submitted such a proposal at a substantially lower value, that entity  in
late  February 1996 proposed a stock-for-stock  merger at an exchange ratio with
an implied value  of $42  per Brandon  share based  on the  other entity's  then
current  stock  price.  However, the  entity  imposed material  conditions  to a
definitive merger  agreement, and  efforts by  Brandon to  satisfy or  eliminate
those  conditions  were unsuccessful.  At the  time that  the Brandon  Board was
considering  Interim  Services'  final  proposal,  which  Interim  Services  had
indicated  would not  be held  open for  an extended  period of  time, the other
entity informed  Brandon that  it was  not in  a position  to proceed  with  any
unconditional merger proposal, although it might consider making a proposal at a
later date, with price and other terms unspecified.
 
    After  review and consideration of these matters, at the February 26 meeting
the Brandon  Board,  with all  members  of  the Special  Committee  present  and
participating,  unanimously approved  the Merger  Agreement and  the Merger with
Interim Services as being fair to and  in the best interests of Brandon and  its
stockholders.  On  February  27, 1996,  the  Merger Agreement  was  executed and
delivered by Brandon and Interim Services.

REASONS FOR APPROVAL OF THE MERGER AGREEMENT BY THE BRANDON BOARD;
RECOMMENDATION OF THE BRANDON BOARD
 
    The reasons the  Brandon Board  approved the Merger  Agreement included  the
following:  (i) the strategic business benefits  of a combination of Brandon and
Interim Services; (ii) the immediate and potential long-term financial  benefits
to  Brandon  shareholders inherent  in the  terms of  the Merger,  including the
Exchange Ratio; (iii) the  opinion of Goldman  Sachs to the  effect that, as  of
February  26, 1996, the Exchange Ratio pursuant to the Merger Agreement was fair
to the  holders  of  Brandon  Common  Stock;  (iv)  the  likelihood  of  further
consolidation  in  the  temporary staffing  industry  and the  potential  of the
Interim Services-Brandon  combination to  enhance Brandon's  competitiveness  in
such an environment; (v) the size and stability of Interim Services' established
business; (vi) the complementary business philosophies and strategies of Brandon
and  Interim Services, and the expectation  that the executives and employees of
the combined entity will  work together effectively to  create a strong  company
with  enhanced  potential  for  success; (vii)  the  complementary  strengths of
Brandon and Interim Services and the ability of the combined entity to offer its
customers a  broader range  of  products and  services  than either  Brandon  or
Interim  Services presently offers; (viii) the potential for the combined entity
to  achieve  economies  of  scale   which  will  ultimately  benefit   Brandon's
stockholders;  (ix) the  existence of Interim  Services' facilities  in over 900
locations, which  is expected  to  enhance significantly  Brandon's  post-Merger
ability to enter markets in which it currently has no offices; (x) the prospects
for  future growth and increased market recognition of the combined entity; (xi)
the relative  share  ownership  which  Brandon stockholders  will  have  in  the
combined  Brandon-Interim  Services entity;  (xii) the  greater public  float of
Interim Common Stock compared with Brandon Common Stock; (xiii) the existence of
market conditions  which  favored  a business  combination  transaction  in  the
current  time  frame;  (xiv)  the  fact that  the  Merger  Agreement  was viewed
favorably by Ira B. Brown and Myra Brown, who together control approximately 25%
of the outstanding  Brandon Common Stock;  (xv) the expressed  desire of Ira  B.
Brown,  age 69, to  retire from an  active management role  with Brandon and the
implications of such retirement to Brandon  as an independent entity; (xvi)  the
specific  terms and  conditions contained  in the  Merger Agreement;  (xvii) the
other expressions  of interest  which the  Brandon Board  had received;  (xviii)
information  regarding the entities  making such expressions  of interest; (xix)
the uncertainties associated  with such  expressions of interest;  and (xx)  the
relative value being offered to Brandon stockholders in the Merger compared with
the  value which such stockholders were likely  to receive over the coming years
if Brandon management continued to operate the company independently.
 
    In approving the Merger, the Brandon Board did not specifically identify any
one factor or group of factors as  being more significant than any other  factor
in the decision making process, although individual directors may have given one
or more factors more weight than other factors.
 
THE BRANDON BOARD BELIEVES THAT THE MERGER AGREEMENT AND THE MERGER ARE FAIR TO,
AND  IN THE  BEST INTEREST  OF, BRANDON  AND ITS  STOCKHOLDERS. ACCORDINGLY, THE
BRANDON BOARD HAS UNANIMOUSLY APPROVED THE  MERGER AGREEMENT AND THE MERGER  AND
UNANIMOUSLY  RECOMMENDS THAT BRANDON STOCKHOLDERS VOTE FOR APPROVAL AND ADOPTION
OF THE MERGER AGREEMENT AND THE MERGER.
 
INTERIM SERVICES' REASONS FOR THE MERGER; RECOMMENDATION OF INTERIM SERVICES'
BOARD OF DIRECTORS
 
    Numerous factors  were  taken  into consideration  by  Interim  Services  in
entering   into  the  Merger  Agreement,   including,  without  limitation,  the
personnel, operations, prospects, assets,  obligations, and earnings of  Brandon
and  judgments  with respect  to  the prospects  for  both Interim  Services and
Brandon, as well as Interim Services' belief that combining Brandon with Interim
Services' existing operations will enhance the presence of both companies in the
flexible staffing market, and, in particular, in the IT staffing sector of  such
market, thereby enabling them to offer their customers a broader and more varied
array  of  services. In  addition, the  Interim Board  received and  reviewed an
opinion from DLJ, its  financial advisor, stating in  part that, as of  February
27,  1996, the  consideration to  be paid  by Interim  Services pursuant  to the
Merger Agreement  was  fair  to the  holders  of  Interim Common  Stock  from  a
financial point of view.
 
                                       29
<PAGE>
    Interim  Services'  management  believes  that  the  addition  of  Brandon's
operations to the  IT unit of  Interim Services offers  a number of  advantages,
including  (i) broad geographic coverage of its offices which complement current
operations; (ii)  achievement of  a critical  mass for  the total  IT  operation
including  Brandon; and (iii) vertical expansion  of the scope of services which
the IT unit can offer. Brandon's service offering is complementary to the skills
that Interim Services currently offers in that Brandon provides skills which are
the foundation of information resource staffing needs, particularly in the  area
of help desk and data-center operations. These services supplement primarily the
consulting and testing skills offered by Interim Services.
 
    Interim   Services'   management   believes  that   there   are  substantial
opportunities for cross-selling between the companies, particularly through  the
Interim  On-Premise  concept.  In  addition, the  national  accounts  of Interim
Services will provide many  opportunities to offer  Brandon's skills to  clients
and  enhance  the scope  of  services currently  provided.  Further, as  part of
Interim Services, Brandon will have the advantage of introduction at high levels
to the clients of Interim Services.
 
    Interim Services expects to benefit from access to Brandon's client base  in
regard  to cross-selling  of clerical,  light industrial,  legal, accounting and
other skills as well as many Interim On-Premise opportunities. Interim Services'
management believes that, after the  Merger, expansion of Brandon's network  may
be  enhanced through a  number of factors,  including lower start-up  costs as a
result of the possibility for  sharing space with the  network of more than  900
Interim Services offices and increased revenue growth through opportunities with
Interim Services' established client base.
 
    In  view of the wide variety of factors considered, Interim Services did not
find it practicable to quantify or otherwise attempt to assign relative  weights
to  the specific factors  considered in making  its determination. Consequently,
the Interim Board did not quantify  the assumptions and results of its  analysis
in reaching its decision to enter into the Merger Agreement.
 
THE  INTERIM  BOARD  BELIEVES THAT  THE  MERGER AGREEMENT  AND  THE TRANSACTIONS
CONTEMPLATED THEREBY ARE FAIR TO, AND IN THE BEST INTERESTS OF, INTERIM SERVICES
AND ITS STOCKHOLDERS.  ACCORDINGLY, THE INTERIM  BOARD HAS UNANIMOUSLY  APPROVED
THE  MERGER AGREEMENT AND THE  ISSUANCE OF INTERIM COMMON  STOCK PURSUANT TO THE
MERGER AGREEMENT AND UNANIMOUSLY RECOMMENDS  THAT INTERIM STOCKHOLDERS VOTE  FOR
APPROVAL OF THE ISSUANCE OF INTERIM SERVICES COMMON STOCK PURSUANT TO THE MERGER
AGREEMENT.
 
EFFECTIVE TIME; CLOSING DATE
 
    If  (i) the  issuance of  the Interim  Common Stock  pursuant to  the Merger
Agreement is  approved by  holders of  a majority  of the  Interim Common  Stock
voting  at the Interim Special Meeting; (ii) the Merger Agreement is approved at
the Brandon Special Meeting by holders  of a majority of the outstanding  shares
of  Brandon  Common Stock;  and (iii)  all  other conditions  to the  Merger are
satisfied or waived  (SEE "CERTAIN  PROVISIONS OF  THE MERGER  -- CONDITIONS  TO
CONSUMMATION OF THE MERGER"), the Merger will be consummated and effected at the
time  a Certificate of Merger is filed  with the Secretary of State of Delaware.
The time at which the Merger becomes effective is referred to as the  "Effective
Time."  The Merger  Agreement provides  that Interim  Services and  Brandon will
cause Certificates of Merger  to be filed  and recorded on  the Closing Date  in
accordance  with the applicable  provisions of the  Delaware General Corporation
Law. The  Merger Agreement  may be  terminated prior  to the  Effective Time  by
either  Interim Services or Brandon in  certain circumstances, whether before or
after the approval of the Merger Agreement  and the approval of the issuance  of
Interim  Common Stock pursuant  to the Merger Agreement,  by the stockholders of
Brandon and  Interim  Services, respectively.  SEE  "CERTAIN PROVISIONS  OF  THE
MERGER AGREEMENT -- TERMINATION." The closing of the Merger (the "Closing") will
take place as soon as practicable after satisfaction or waiver of the conditions
set  forth in  the Merger  Agreement (other  than the  delivery of certificates,
opinions and other instruments  and documents to be  delivered at the  Closing),
but in no event later than five business days thereafter (the "Closing Date") at
such time and place as Interim Services and Brandon shall mutually agree.

<PAGE>
FORM OF THE MERGER
 
    At the Effective Time, Merger Sub will be merged with and into Brandon, with
Brandon  as the Surviving  Corporation and a  wholly-owned subsidiary of Interim
Services.
 
MERGER CONSIDERATION
 
    At the Effective Time, each outstanding  share of Brandon Common Stock  will
be  converted into  the right  to receive 0.88  shares of  Interim Common Stock,
subject to certain anti-dilution adjustments. However, shares of Brandon  Common
Stock which are held by Brandon as treasury shares, and shares of Brandon Common
Stock  held by  Interim Services,  Merger Sub  or any  other direct  or indirect
subsidiary of Interim Services,  will be cancelled and  thus not converted  into
Interim Common Stock. Cash shall be paid in lieu of fractional shares of Interim
Common Stock, based upon the Median Pre-Closing Price per whole share of Interim
Common  Stock. The "Median Pre-Closing Price" is defined in the Merger Agreement
as the Median Price  of Interim Common Stock  calculated based upon the  closing
price  of Interim Common Stock during the first 20 of the 25 consecutive trading
days immediately  preceding  the  closing  date.  The  "Median  Price"  will  be
determined  by taking the average of the  closing prices of Interim Common Stock
left after discarding the seven lowest  and seven highest closing prices in  the
20-day  period.  Therefore,  after  the Effective  Time  and  upon  surrender of
certificates representing  their  Brandon  Common Stock,  each  holder  of  such
certificates  will receive:  (i) a certificate  evidencing that  number of whole
shares of Interim Common  Stock which such  holder has the  right to receive  in
exchange  for Brandon Common  Stock in accordance with  the Exchange Ratio, (ii)
cash in lieu of fractional shares of  Interim Common Stock to which such  holder
may  be  entitled, and  (iii) any  dividends or  other distributions  on Interim
Common Stock due and payable  (with a record date  after the Effective Time)  to
which such holder is entitled (collectively, the "Merger Consideration").
 
TREATMENT OF OPTIONS
 
    At  the  Effective  Time,  each outstanding  Brandon  Stock  Option  will be
converted into an option to purchase Interim Common Stock, wherein (i) the right
to purchase shares of Brandon Common Stock pursuant to the Brandon Stock  Option
will  be converted  into the  right to  purchase that  same number  of shares of
Interim Common Stock multiplied by the Exchange Ratio, (ii) the option  exercise
price  per share of  Interim Common Stock  will be the  previous option exercise
price per share of Brandon Common Stock divided by the Exchange Ratio, and (iii)
in all other material respects, the option will be subject to the same terms and
conditions as governed the Brandon Stock Option on which it was based, including
the length of time within which the option may be exercised and for any  options
which are "incentive stock options" (as defined in Section 422 of the Code), the
conversions  will  be and  are  intended to  be effected  in  a manner  which is
consistent with Section 424(a) of the Code.
 
    Under the stock  option plans pursuant  to which the  Brandon Stock  Options
were  issued, all Brandon Stock Options held  by participants in the plans which
are not  yet exercisable  become  immediately exercisable  and vested  upon  the
occurrence  of a "Change in Control," which is defined such that the Merger will
constitute a  Change in  Control. As  a result,  all outstanding  Brandon  Stock
Options  will  be  converted by  virtue  of  the Merger  into  fully  vested and
exercisable options to purchase  shares of Interim Common  Stock. The number  of
shares  of Interim Common Stock  purchasable under the options  will be equal to
the number of shares of Brandon Common Stock previously purchasable,  multiplied
by the Exchange Ratio.
 
IRREVOCABLE PROXY
 
    Ira  B.  Brown and  Myra  Brown, who  collectively  own 1,099,760  shares of
Brandon Common Stock, or 25.0% of the shares of Brandon Common Stock outstanding
on the Record Date, have each entered into an Irrevocable Proxy, dated  February
27,  1996  (the "Irrevocable  Proxy"). Pursuant  to  the Irrevocable  Proxy, the
Browns have irrevocably granted to Raymond Marcy, Roy Krause and John B.  Smith,
designees  of Interim Services, the power to vote their shares of Brandon Common
Stock in  favor of  the  Merger and  the approval  and  adoption of  the  Merger
Agreement.  The Browns have not given any  Interim Services designees a proxy to
vote on any matters other than the Merger.
 
                                       31
<PAGE>
    The Irrevocable Proxy  will automatically  terminate (i) on  the earlier  of
August  27, 1996 or the  termination of the Merger  Agreement in accordance with
its terms, (ii) if the Brandon Board does not recommend, or modifies or rescinds
its recommendation, that Brandon  stockholders vote in favor  of the Merger,  or
modifies or rescinds its approval of the Merger Agreement, or resolves to do any
of  the  foregoing, or  (iii)  if the  Brandon  Board enters  into  a definitive
agreement contemplating, announces  or approves an  Acquisition Transaction  (as
hereinafter defined) after determining, in good faith and upon advice of outside
counsel,  that  such approval  was necessary  in the  exercise of  its fiduciary
duties under applicable laws.
 
    The  Irrevocable   Proxy  is   attached   as  Exhibit   B  to   this   Proxy
Statement/Prospectus and is incorporated herein by reference.
 
NO APPRAISAL RIGHTS
 
    Neither  Brandon stockholders nor Interim Services stockholders are entitled
to dissenter's rights of appraisal in connection with the Merger.
 
OPINION OF FINANCIAL ADVISOR TO INTERIM SERVICES
 
    In its  role as  financial advisor  to Interim  Services, DLJ  was asked  by
Interim  Services to render its opinion to  the Interim Board as to the fairness
from a financial point of  view to its stockholders  of the consideration to  be
paid by Interim Services pursuant to the Merger Agreement.
 
    On  February 27, 1996 and April 23, 1996, DLJ delivered its written opinions
(the April 23, 1996,  opinion herein referred  to as the  "DLJ Opinion") to  the
Interim  Board  that,  as  of  such date  and  subject  to  the  assumptions and
limitations described in such opinions, the consideration to be paid by  Interim
Services  pursuant  to  the  Merger  Agreement  was  fair  to  Interim Services'
stockholders from a financial point of view.
 
    A COPY OF THE DLJ OPINION IS ATTACHED TO THIS PROXY STATEMENT/PROSPECTUS  AS
EXHIBIT  C.  STOCKHOLDERS ARE  URGED TO  READ  THE OPINION  IN ITS  ENTIRETY FOR
ASSUMPTIONS MADE, PROCEDURES  FOLLOWED, OTHER MATTERS  CONSIDERED AND LIMITS  OF
THE  REVIEW OF DLJ.  THE SUMMARY OF THE  OPINION OF DLJ SET  FORTH IN THIS PROXY
STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL  TEXT
OF  SUCH OPINION.  THE DLJ  OPINION WAS  PREPARED FOR  THE INTERIM  BOARD AND IS
DIRECTED ONLY TO THE FAIRNESS  AS OF APRIL 23, 1996,  FROM A FINANCIAL POINT  OF
VIEW, OF THE CONSIDERATION TO BE PAID BY INTERIM SERVICES PURSUANT TO THE MERGER
AGREEMENT  AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER AS TO HOW
TO VOTE AT EITHER THE INTERIM SPECIAL MEETING OR THE BRANDON SPECIAL MEETING.
 
    The DLJ Opinion  does not constitute  an opinion  as to the  price at  which
Interim  Common  Stock  will actually  trade  at  any time.  No  restrictions or
limitations were  imposed by  the Interim  Board upon  DLJ with  respect to  the
investigations made or the procedures followed by DLJ in rendering its opinion.
 
    In  arriving at its opinion, DLJ reviewed the Merger Agreement and financial
and other information that was publicly available or furnished to it by  Interim
Services  and Brandon,  including information  provided during  discussions with
their respective  managements.  Included  in  the  information  provided  during
discussions  with the respective managements  were certain financial projections
of Brandon for the period beginning October  2, 1995 and ending October 1,  1998
prepared  by  the management  of Brandon  and  certain financial  projections of
Interim Services for the  period beginning January 1,  1996 and ending  December
31,  1999  prepared by  the  management of  Interim  Services. In  addition, DLJ
compared certain financial and securities  data of Interim Services and  Brandon
with  various other  companies whose  securities are  traded in  public markets,
reviewed prices and premiums paid  in other business combinations and  conducted
such  other  financial  studies,  analyses  and  investigations  as  DLJ  deemed
appropriate for purposes of its opinion.
 
                                       32
<PAGE>
    In arriving  at its  opinion,  DLJ relied  upon  and assumed  the  accuracy,
completeness and fairness of all of the financial and other information provided
or that was otherwise reviewed by DLJ. With respect to the financial projections
reviewed  and discussed, DLJ  assumed that they were  reasonably prepared on the
basis reflecting the  best currently  available estimates and  judgments of  the
managements  of  Interim Services  and Brandon  as to  the future  operating and
financial performance of Interim Services and Brandon, respectively. DLJ  relied
as  to  all  legal matters  on  the  advice of  Interim  Services'  counsel. The
following is a summary of certain of the analyses performed by DLJ:
 
    COMPARABLE COMPANIES ANALYSIS.  DLJ  reviewed and analyzed certain  publicly
available  financial  and market  information  for selected  staffing companies,
including   Accustaff,   Inc.,   Barrett   Business   Services,   Inc.,   Butler
International,  Inc., Career Horizons,  Inc., CDI Corp.,  Corestaff, Inc., Heist
Corp., Hooper Holmes, Inc., Keane,  Inc., Kelly Services, Inc., Manpower,  Inc.,
Norrell  Corp., Olsten Corp., On Assignment, Inc., Right Management Consultants,
Robert Half  International, Inc.,  Staff Builders,  Inc., and  Volt  Information
Sciences,   Inc.  (the  "Comparable  Staffing   Companies"),  and  for  selected
information technology  staffing  companies,  including  Analysts  International
Corp., Computer Sciences Corp., Alternative Resources Corp., American Management
Systems,  Inc., Computer Horizons Corp., Technology Solutions Co., Computer Task
Group, Inc., Keane, Inc. and CIBER, Inc. (the "Comparable Information Technology
Staffing Companies"  and,  together  with  the  Comparable  Staffing  Companies,
collectively the "Comparable Companies"). DLJ noted that no company reviewed was
identical  to Brandon and  that, accordingly, the  Comparable Companies analysis
necessarily involves complex considerations and judgments concerning differences
in financial and  operating characteristics  of Brandon and  other factors  that
would  affect the  value of  the companies  to which  it is  being compared. DLJ
calculated a range of  market multiples for  the Comparable Companies  including
the equity market price as a multiple of historical and projected (based on Wall
Street   equity  research  analysts'  estimates)  earnings  per  share  and  the
enterprise value (defined as market  capitalization plus total debt less  excess
cash and cash equivalents) as a multiple of historical revenues, earnings before
interest,  taxes, depreciation  and amortization ("EBITDA")  and earnings before
interest and taxes ("EBIT") after removing the high and low contributions.  This
analysis  indicated that the mean multiples,  excluding the high and low values,
of revenues, EBITDA, EBIT and net  income for the Comparable Staffing  Companies
were  1.0x,  13.8x,  15.4x  and  28.1x,  respectively,  and  for  the Comparable
Information Technology Staffing  Companies were  2.0x, 17.5x,  23.3x and  41.1x,
respectively,  as of April 22, 1996. DLJ applied those same multiples to Brandon
and derived a reference range of implied equity values for Brandon of $22.02  to
$55.72 per share.
 
    ANALYSIS  OF COMPARABLE TRANSACTIONS.  DLJ  analyzed the purchase prices and
multiples paid or  proposed to  be paid, to  the extent  publicly available,  of
selected  merger and  acquisition transactions  of companies  in the information
technology  services  industry  that  were  announced  since  January  1,   1993
(collectively,  the  "Comparable  Transactions").  DLJ noted  that  none  of the
selected  transactions  reviewed   was  identical  to   the  Merger  and   that,
accordingly,  the  analysis  of  comparable  transactions  necessarily  involves
complex consideration  and judgments  concerning  differences in  financial  and
operating  characteristics of  Brandon and other  factors that  would affect the
acquisition value  of  the  Comparable Transactions.  DLJ  determined  that  the
relevant  multiples derived from the Comparable Transactions were 1.8 x revenues
and 17.2 x EBITDA after removing  the high and low contributions. Applying  such
multiples,  DLJ derived a reference range of equity values for Brandon of $36.43
to $42.95 per share.
 
    DISCOUNTED CASH  FLOW  ANALYSIS.    DLJ performed  a  discounted  cash  flow
analysis of the projected cash flows of Brandon for the five fiscal years ending
December  31, 2000, based upon certain projections of Brandon's future financial
performance as provided to DLJ from Brandon and its representatives and reviewed
by  Interim  Services'  management.   Using  such  financial  information,   DLJ
calculated the unlevered after-tax cash flows and discounted such projected cash
flows  back to  January 1,  1996 using  discount rates  ranging from  12% to 16%
(chosen to reflect the weighted average cost of capital for Brandon based on the
betas of Comparable Information Technology Staffing Companies). To estimate  the
terminal  value  of Brandon  at the  end  of the  five-year period,  DLJ applied
 
                                       33
<PAGE>
a range of terminal multiples of 10.0x to 13.0x projected fiscal 2000 EBITDA and
discounted such value  estimates back to  January 1, 1996  using discount  rates
ranging  from 12%  to 16%. DLJ  then summed  the present value  of the unlevered
after-tax cash flows and  terminal value to derive  a reference range of  equity
values for Brandon of $34.62 to $49.87 per share.
 
    CONTRIBUTION  ANALYSIS.    DLJ  analyzed  Interim  Services'  and  Brandon's
relative contribution to the combined company with respect to certain  financial
measurements,  including revenues,  EBITDA, EBIT,  net income,  total assets and
book value of equity. As a result  of the Merger, Brandon stockholders will  own
approximately  25.5% of the  outstanding Interim Common  Stock which compares to
Brandon's contribution based on Brandon's twelve months ended December 31,  1995
and  Interim Services'  estimated fiscal  year ended  December 29,  1995, to the
combined companies of 9.6% of revenues, 18.3% of EBITDA, 22.4% of EBIT, 26.2% of
net income, 7.9% of total assets and 13.2% of book value of equity.
 
    PREMIUMS PAID ANALYSIS.  DLJ  determined the percentage premium  represented
by  the offer price  over the trading prices  one day, one  week, and four weeks
prior to the announcement date  of selected merger and acquisition  transactions
involving  companies not  necessarily comparable to  Brandon. These transactions
ranged in enterprise value from $100 million to $500 million and occurred  since
January 1, 1995. The average of the premiums paid for such selected transactions
over  the  trading  prices, one  day,  one week,  and  four weeks  prior  to the
announcement date were 29.5%, 32.5% and 43.5%, respectively. DLJ also determined
the percentage premium  paid represented  by the  offer price  over the  trading
prices  one day,  one week,  and four  weeks prior  to the  announcement date of
selected merger and acquisition transactions involving companies in the software
development and  computer  services  industries. These  transactions  ranged  in
enterprise value from $100 million to $3.5 billion and occurred since January 1,
1993.  The average of the premiums paid  for such selected transactions over the
trading prices, one day, one week, and four weeks prior to the announcement date
were 33.1%, 35.2%  and 47.0%,  respectively. For the  proposed transaction,  DLJ
derived the premium to be paid by Interim Services based on the implied purchase
price  of  Brandon's  stock,  which  is equal  to  the  exchange  ratio  of 0.88
multiplied by Interim  Services' stock price  on April 22,  1996 of $37.50,  one
day,  one week, and four weeks prior to the announcement date. The premiums paid
for the proposed transaction over the trading prices one day, one week and  four
weeks prior to the announcement date were 24.5%, 30.0%, and 22.2%, respectively.
 
    PRO FORMA MERGER ANALYSIS.  DLJ analyzed certain pro forma financial effects
resulting  from the Merger. In conducting  its analysis, DLJ relied upon certain
assumptions  described  above   and  financial  projections   provided  by   the
managements  of both  Interim Services and  Brandon. DLJ analyzed  the pro forma
financial effect  of  combining  Interim Services  and  Brandon.  Such  analysis
indicated, among other things, that earnings per share ("EPS") for the pro forma
combined  company would be modestly greater than EPS for Interim Services alone.
The results of the pro forma combination analysis are not necessarily indicative
of future operating results or financial position.
 
    The summary set forth above does not purport to be a complete description of
the presentation by DLJ to the Interim Board or the analyses performed by DLJ in
arriving at its opinion. The preparation of a fairness opinion involves  various
determinations  as to  the most  appropriate and  relevant methods  of financial
analysis and the application  of these methods  to the particular  circumstances
and,  therefore, such an  opinion is not readily  suited to summary description.
The preparation of a fairness opinion does not involve a mathematical evaluation
or weighing of the  results of the individual  analyses performed, but  requires
DLJ  to  exercise  its professional  judgement  -  based on  its  experience and
expertise - in considering a wide variety of analyses taken as a whole. Each  of
the  analyses conducted by DLJ  was carried out in  order to provide a different
perspective on  the  transaction  and  add  to  the  total  mix  of  information
available.  DLJ did not form a conclusion as to whether any individual analysis,
considered in  isolation,  supported or  failed  to  support an  opinion  as  to
fairness.  Rather, in reaching its conclusion, DLJ considered the results of the
analyses in light of each other and ultimately reached its opinion based on  the
results  of all analyses taken as a whole. DLJ did not place particular reliance
or weight on any individual analysis,  but instead concluded that its  analyses,
taken  as a whole, supported its  determination. In performing its analyses, DLJ
made numerous assumptions
 
                                       34

with respect to industry performance, business and economic conditions and other
matters. The analyses performed by DLJ are not necessarily indicative of  actual
values or future results, which may be significantly more or less favorable than
suggested by such analyses.
 
    DLJ's  opinion is necessarily based on economic, market, financial and other
conditions as they existed on, and on  the information made available to DLJ  as
of   April  23,  1996.  It  should   be  understood  that,  although  subsequent
developments may affect its opinion, DLJ does not have any obligation to update,
revise or reaffirm its opinion.
 
    DLJ, as part of its investment banking services, is regularly engaged in the
valuation of businesses and securities in connection with mergers, acquisitions,
underwritings, sales  and  distributions  of  listed  and  unlisted  securities,
private  placements and valuations for estate,  corporate and other purposes. In
the ordinary course of business, DLJ may actively trade the equity securities of
Interim and Brandon for its own account and for the account of its customers and
may at any time hold a long or short position in such securities.
 
    For its  services  as  financial  advisor, DLJ  will  receive  an  aggregate
transaction  fee of $1.3 million, of which $350,000 became payable upon delivery
of DLJ's opinion of February 27,  1996, $50,000 became payable upon delivery  of
DLJ's  opinion  of  April  23,  1996,  and  the  balance  becomes  payable  upon
consummation of the Merger.  Interim Services has also  agreed to reimburse  DLJ
for  its reasonable  out-of-pocket expenses.  In addition,  Interim Services has
agreed  to  indemnify  DLJ  and  its  affiliates  against  certain  liabilities,
including those arising under the federal securities laws.
 
OPINION OF FINANCIAL ADVISOR TO BRANDON
 
    On  February  26, 1996,  Goldman  Sachs delivered  its  oral opinion  to the
Brandon Board that as of the date  of such opinion, the Exchange Ratio  pursuant
to the Merger Agreement was fair to the holders of Brandon Common Stock. Goldman
Sachs  subsequently  delivered  to the  Brandon  Board a  written  opinion dated
February 27,  1996  confirming  its oral  opinion.  Goldman  Sachs  subsequently
confirmed its February 27, 1996 opinion by delivery of its written opinion dated
as of April 23, 1996.
 
    THE  FULL TEXT OF THE WRITTEN OPINION OF GOLDMAN SACHS DATED AS OF APRIL 23,
1996, WHICH SETS FORTH ASSUMPTIONS  MADE, MATTERS CONSIDERED AND LIMITATIONS  ON
THE  REVIEW UNDERTAKEN  IN CONNECTION  WITH THE  OPINION, IS  ATTACHED HERETO AS
EXHIBIT D  TO THIS  PROXY  STATEMENT/PROSPECTUS AND  IS INCORPORATED  HEREIN  BY
REFERENCE.  HOLDERS OF BRANDON COMMON STOCK ARE  URGED TO, AND SHOULD, READ SUCH
OPINION IN ITS ENTIRETY.
 
    In connection with its opinion, Goldman Sachs reviewed, among other  things,
(i) the Merger Agreement; (ii) this Proxy Statement/Prospectus; (iii) the Annual
Reports  to Stockholders and Annual Reports on Form 10-K of Brandon for the five
fiscal years ended October 2, 1995; (iv) the Annual Reports to Stockholders  and
Annual  Reports on Form 10-K of Interim Services for the fiscal year ended March
25, 1994, the  fiscal year ended  December 30,  1994 and the  fiscal year  ended
December  29, 1995 and the Prospectus of Interim Services dated January 27, 1994
which includes audited financial  statements of Interim  Services for the  three
fiscal years ended March 26, 1993 and for the 26 weeks ended September 24, 1993;
(v)  certain interim reports to stockholders  and Quarterly Reports on Form 10-Q
of Brandon and Interim Services; (vi) certain other communications from  Brandon
and  Interim  Services  to  their  respective  stockholders;  and  (vii) certain
internal financial  analyses  and forecasts  for  Brandon and  Interim  Services
prepared  by their respective  managements. Goldman Sachs  also held discussions
with members of the senior management of Brandon and Interim Services  regarding
the  past  and  current  business operations,  financial  condition,  and future
prospects of their respective companies. In addition, Goldman Sachs reviewed the
reported price and trading activity for the Brandon Common Stock and the Interim
Common Stock,  compared  certain  financial and  stock  market  information  for
Brandon  and  Interim  Services  with  similar  information  for  certain  other
companies the securities of  which are publicly  traded, reviewed the  financial
terms of certain recent business combinations in the temporary staffing industry
specifically and other industries generally and performed such other studies and
analyses as it considered appropriate.
 
                                       35
<PAGE>
    Goldman  Sachs relied without independent verification upon the accuracy and
completeness of all of  the financial and other  information reviewed by it  for
purposes  of its opinion. In addition, Goldman Sachs has not made an independent
evaluation or appraisal  of the  assets and  liabilities of  Brandon or  Interim
Services  or any of their subsidiaries and  Goldman Sachs has not been furnished
with any such evaluation or appraisal.
 
    The following is  a summary  of certain of  the financial  analyses used  by
Goldman  Sachs in connection with providing  its oral opinion to Brandon's Board
of Directors on February 26, 1996. Goldman Sachs utilized substantially the same
type of  financial analyses  in connection  with providing  its written  opinion
dated February 27, 1996 and the written opinion attached hereto as Exhibit D.
 
             (i)  HISTORICAL STOCK TRADING ANALYSIS.  Goldman Sachs reviewed the
        historical trading prices and volumes  for the Brandon Common Stock  and
        Interim   Common  Stock.   In  addition,  Goldman   Sachs  analyzed  the
        consideration to be received by holders of Brandon Common Stock pursuant
        to the  Merger in  relation to  the historical  average exchange  ratios
        between  Brandon Common  Stock and  Interim Common  Stock. Such analysis
        indicated that the  Exchange Ratio  pursuant to  the Merger  represented
        premiums  over the exchange ratio between the weighted average price per
        share of Brandon Common Stock and  the weighted average price per  share
        of  Interim Common Stock over the 60 day, 6 month, 12 month and 18 month
        periods  to  February  23,  1996  of  24.4%,  31.6%,  18.6%  and  18.7%,
        respectively.
 
              (ii)   SELECTED  COMPANIES ANALYSIS.   Goldman  Sachs reviewed and
        compared certain financial information  relating to Brandon and  Interim
        Services  to  corresponding  financial  information,  ratios  and public
        market  multiples   for   six   publicly   traded   specialty   staffing
        corporations, Alternative Resources Corporation, CDI Corporation, Keane,
        Inc.,   Olsten  Corporation,   On  Assignment,  Inc.   and  Robert  Half
        International, Inc. (the  "Specialty Staffing  Selected Companies")  and
        for  ten publicly  traded traditional  staffing corporations, Affiliated
        Computer  Services,  Inc.,  Barrett  Business  Services,  Inc.,   Career
        Horizons,  Inc., CORESTAFF,  Inc., Kelly Services,  Inc., Manpower Inc.,
        Norrell Corporation, Personnel Group of America, SOS Staffing  Services,
        Inc.  and  Staff  Builders,  Inc.  (the  "Traditional  Staffing Selected
        Companies"  and,  collectively  with  the  Specialty  Staffing  Selected
        Companies,  the  "Selected  Companies").  Goldman  Sachs  calculated and
        compared various  financial  multiples  and  ratios.  The  multiples  of
        Brandon  and Interim Services were calculated using prices of $26.25 per
        share and $39.63 per share, respectively, the closing prices on February
        23, 1996. The multiples and ratios for Brandon were based on information
        provided by its management  and the multiples  for Interim Services  and
        for  each  of  the Selected  Companies  were  based on  the  most recent
        publicly available information. With respect to the Selected  Companies,
        Goldman  Sachs considered levered market capitalization (market value of
        common equity plus debt less cash) as a multiple of latest twelve months
        ("LTM") sales, as  a multiple  of LTM earnings  before interest,  taxes,
        depreciation  and  amortization  ("EBITDA")  and as  a  multiple  of LTM
        earnings before interest and taxes ("EBIT"). Goldman Sachs' analyses  of
        the  Specialty Staffing Selected Companies  and the Traditional Staffing
        Selected Companies,  indicated levered  multiples  of LTM  sales,  which
        ranged  from 0.4x to  3.5x and 0.2x and  1.6x, respectively, LTM EBITDA,
        which ranged from 8.6x to 31.6x and 5.7x to 22.0x, respectively, and LTM
        EBIT, which ranged from 10.2x to 32.7x and 6.4x to 26.7x,  respectively,
        compared  to levered multiples  of sales, EBITDA and  EBIT of 1.3x, 9.8x
        and 10.7x,  respectively,  for  Brandon  and  0.7x,  11.7x,  and  16.6x,
        respectively,  for Interim Services. Goldman  Sachs also considered, for
        the Specialty Staffing Selected  Companies and the Traditional  Staffing
        Selected Companies, estimated calendar year 1995 and 1996 price/earnings
        ratios,   which  ranged  from  21.0x  to   42.8x  and  13.0x  to  56.4x,
        respectively, for estimated calendar  year 1995 and  14.4x to 33.2x  and
        10.6x  to 38.3x, respectively, for estimated calendar year 1996 compared
        to estimated calendar year 1995 and 1996 price/earnings ratios of  18.8x
        and  15.9x, respectively, for Brandon and 26.4x and 21.5x, respectively,
        for Interim Services.

<PAGE>
             (iii)  DISCOUNTED  CASH FLOW ANALYSIS.   Goldman Sachs performed  a
        discounted cash flow analysis: (a) using from 1 to 10 years of Brandon's
        management  projections (the "Management Case") and  (b) using from 1 to
        10 years of 20% annual growth of sales and static operating margins (the
        "Second Case"). All future cash  flows were discounted to present  value
        using discount rates from 11% to 13%.
 
             At the end  of each such 1 to 10  year period, a terminal value was
        calculated using a 4.5% rate of growth of free cash flow in  perpetuity.
        These  terminal  values  were  then discounted  to  present  value using
        discount rates from 11% to 13%.
 
             In the  Management Case the  implied per share  values ranged  from
        $20.00,  using one year of management projections and a discount rate of
        13%, to  $94.71 using  10 years  of management  projections and  an  11%
        discount  rate. In the  Second Case the implied  per share values ranged
        from $19.40,  using  one  year  of 20%  annual  sales  growth  and  flat
        operating  margins and a 13% discount rate, to $55.23, using 10 years of
        20% annual sales growth and flat  operating margins and an 11%  discount
        rate.
 
               (iv)   SELECTED  TRANSACTIONS ANALYSIS.   Goldman  Sachs analyzed
        certain information relating to  selected transactions in the  temporary
        employment  and  staffing service  industry  since 1993,  (the "Selected
        Transactions").  Such   analysis  indicated   that  for   the   Selected
        Transactions  (i) levered aggregate  consideration as a  multiple of LTM
        revenues ranged from  0.4x to 1.6x  for specialty staffing  and 0.2x  to
        4.5x  for  traditional staffing,  as compared  to  1.8x for  the levered
        aggregate consideration  to  be  received in  the  Merger,  (ii)  equity
        consideration as a multiple of LTM net income ranged from 11.1x to 33.3x
        for  specialty staffing and  2.9x to 20.7x  for traditional staffing, as
        compared to 26.3x for the equity consideration to be paid in the  Merger
        and  (iii) levered  aggregate consideration  as a  multiple of  LTM EBIT
        ranged from 6.9x to 17.9x for  specialty staffing and 2.3x to 11.2x  for
        traditional  staffing, as  compared to  15.5x for  the levered aggregate
        consideration to  be paid  in the  Merger. Goldman  Sachs noted  in  the
        course   of  this  analysis  that   publicly  available  information  on
        transactions in the temporary  employment and staffing service  industry
        was limited.
 
             (v)   PRO FORMA MERGER ANALYSIS.   Goldman Sachs prepared pro forma
        analyses of the financial impact of the Merger. Using earnings estimates
        for Brandon prepared by its management for the years 1996 and 1997,  and
        IBES  median earnings estimates for Interim  Services for 1996 and 1997,
        Goldman Sachs compared the earnings per share ("EPS") of Brandon  Common
        Stock,  on a  standalone basis, to  the EPS  of the common  stock of the
        combined companies on a  pro forma basis.  Goldman Sachs performed  this
        analysis  based on a price  of $26.25 per Share  (the per Share price of
        Brandon on February  23, 1996) of  Brandon Common Stock  and $39.63  per
        share  (the per share price of Interim Services on February 23, 1996) of
        Interim Common Stock under the following two scenarios: (a) assuming  no
        synergies  resulting from the combination and (b) assuming $1 million in
        pre-tax  synergies  resulting  from  the  combination.  Based  on   such
        analyses,  the  proposed  transaction  would  be  accretive  to  Interim
        Services' stockholders on an EPS basis in each of the above scenarios in
        the years 1996 and 1997.
 
            (vi)   CONTRIBUTION AND GIVE-GET  ANALYSIS.  Goldman Sachs  reviewed
        certain   historical  and  estimated   future  operating  and  financial
        information (including  revenues, EBIT,  pretax income,  net income  and
        book  value) for Brandon,  Interim Services, and  the pro forma combined
        entity resulting  from the  Merger based  on, in  the case  of  Brandon,
        actual  1995 calendar year results and management estimates for calendar
        year 1996 and, in the case of Interim Services, information contained in
        the Equity Research Report dated December 19, 1995 of Robert W. Baird  &
        Co. Incorporated. Goldman Sachs performed this analysis based on a price
        of  $26.25 per  share (the  per share price  of Brandon  on February 23,
        1996) of Brandon Common Stock and $39.63 per share (the per share  price
        of  Interim Services on February 23,  1996) of Interim Common Stock. The
        analysis indicated that the Brandon stockholders would receive 25.9%  of
        the  outstanding  common  equity  of the  combined  companies  after the
 
                                       37
<PAGE>
        Merger. Goldman  Sachs  also  analyzed  the  relative  income  statement
        contribution  of Brandon and Interim  Services to the combined companies
        on a pro  forma basis  before taking into  account any  of the  possible
        benefits  that  may  be  realized following  the  Merger.  This analysis
        indicated that in calendar year 1995 Brandon would have contributed 9.8%
        to combined revenues, 19.3% to  combined EBIT, 24.6% to combined  pretax
        income  and  26.2% to  combined  net income  and  in calendar  year 1996
        Brandon would contribute  9.8% to combined  revenues, 17.7% to  combined
        EBIT, 24.4% to combined pretax income and 25.9% to combined net income.
 
               In  addition,  Goldman  Sachs analyzed  the  amount  of accretion
        (dilution) on a per  share basis from Brandon's  perspective of each  of
        the  foregoing measures on a pro  forma basis before taking into account
        any of the possible benefits that may be realized following the  Merger.
        This  analysis showed that  Brandon would experience,  for calendar year
        1995 and 1996, respectively,  a 161.3% and  167.1% revenue accretion,  a
        32.8%  and 47.8% EBIT accretion, a 4.3% and 6.8% pretax income accretion
        and a 1.9% and 0.9% net income dilution.
 
    The preparation  of a  fairness opinion  is  a complex  process and  is  not
necessarily  susceptible to  partial analysis or  summary description. Selecting
portions of the analyses or of the summary set forth above, without  considering
the  analyses  as a  whole, could  create  an incomplete  view of  the processes
underlying Goldman Sachs'  opinion. In arriving  at its fairness  determination,
Goldman  Sachs  considered  the results  of  all  such analyses.  No  company or
transaction used in the above analyses  as a comparison is identical to  Brandon
or  Interim Services or the contemplated transaction. The analyses were prepared
solely for purposes of Goldman Sachs providing its opinion to the Brandon  Board
as  to the fairness of the Exchange Ratio to the holders of Brandon Common Stock
and do not purport to be appraisals  or necessarily reflect the prices at  which
businesses  or securities actually may be sold. Analyses based upon forecasts of
future results are not  necessarily indicative of  actual future results,  which
may  be significantly  more or less  favorable than suggested  by such analyses.
Because such analyses are  inherently subject to  uncertainty, being based  upon
numerous  factors or events  beyond the control the  parties or their respective
advisors, none of Brandon, Interim Services,  Goldman Sachs or any other  person
assumes  responsibility if  future results  are materially  different from those
forecast. As described above,  Goldman Sachs' opinion to  the Brandon Board  was
one  of many factors taken into consideration by the Brandon Board in making its
determination to approve the  Merger Agreement. The  foregoing summary does  not
purport  to be a complete description of the analysis performed by Goldman Sachs
and is qualified by reference to the written opinion of Goldman Sachs set  forth
in Exhibit D hereto.
 
    Goldman  Sachs, as part  of its investment  banking business, is continually
engaged in the valuation of businesses  and their securities in connection  with
mergers   and  acquisitions,  negotiated  underwritings,  competitive  biddings,
secondary distributions of listed  and unlisted securities, private  placements,
and  valuations  for  estate,  corporate and  other  purposes.  Brandon selected
Goldman Sachs as  its financial advisor  because it is  a nationally  recognized
investment  banking firm that has substantial experience in transactions similar
to the Merger.
 
    Goldman Sachs has  provided certain investment  banking services to  Interim
Services  from  time to  time, including  acting as  managing underwriter  of an
initial public offering  of Interim Common  Stock in January  1994, and  Goldman
Sachs  may provide investment banking services  to Interim Services from time to
time in the future.
 
    Pursuant to  a letter  agreement dated  December 13,  1995 (the  "Engagement
Letter"),  Brandon  engaged Goldman  Sachs to  act as  its financial  advisor to
assist  in  responding  to  any  proposals  relating  to  a  strategic  business
combination  with another entity, or any  attempts to acquire control of Brandon
by way of a merger, tender offer, purchase of all or a portion of the assets  or
stock  of Brandon or any contested solicitation  of proxies or otherwise and, in
the event that Brandon determined to pursue a business combination  transaction,
to  assist  Brandon  in  connection  with  such  possible  business  combination
transaction. Brandon paid Goldman Sachs an initial fee of $50,000 at the time of
execution of
 
                                       38
<PAGE>
the Engagement Letter. Pursuant to the  terms of the Engagement Letter,  Brandon
has  agreed to pay Goldman  Sachs upon consummation of  a business combination a
transaction fee, against which the $50,000 initial fee shall be credited,  equal
to  0.9% of the  aggregate consideration of  up to $140,000,000,  plus 5% of any
aggregate  consideration  greater  than   $140,000,000  but  not  greater   than
$160,000,000,  plus 4% of any  aggregate consideration greater than $160,000,000
but not  greater  than $180,000,000,  plus  3% of  any  aggregate  consideration
greater  than $180,000,000. Brandon estimates that, as of the date of this Proxy
Statement/Prospectus, the transaction  fee will be  approximately $1.9  million.
Brandon  has agreed to reimburse Goldman  Sachs for its reasonable out-of-pocket
expenses, including  attorney's fees,  and to  indemnify Goldman  Sachs  against
certain  liabilities, including certain liabilities under the federal securities
laws.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The following discusses only certain federal income tax consequences of  the
Merger  to the United  States citizens or  residents who hold  shares of Brandon
Common Stock.  It  does not  discuss  all the  tax  consequences that  might  be
relevant  to stockholders entitled to special  treatment under the Code (such as
insurance companies, financial institutions,  dealers in securities,  tax-exempt
organizations  or non-U.S. persons)  or to holders who  acquired their shares of
Brandon Common Stock through the exercise of employee stock options or otherwise
as compensation. It  also does not  address the tax  consequences of the  Merger
under state, local or foreign tax laws.
 
    Although  no  ruling  will  be  requested from  the  IRS  regarding  the tax
consequences of the  Merger, it is  a condition precedent  to the obligation  of
each  of Brandon and Interim Services to  consummate the Merger that Brandon and
Interim Services each receive  an opinion from Bryan  Cave LLP that for  federal
income  tax purposes,  the Merger  will constitute  a reorganization  within the
meaning of Section 368(a)  of the Code. Such  opinions are based upon  customary
representations  and  assumptions  made to  such  legal counsel  by  Brandon and
Interim Services with respect to certain factual matters required to qualify the
Merger as a reorganization under the Code. It should be noted that an opinion of
counsel is not binding upon  the IRS. Thus, no assurance  can be given that  the
IRS will not successfully challenge the conclusions set forth therein.
 
    Under  the reorganization provisions  of the Code,  no gain or  loss will be
recognized by stockholders  of Brandon upon  the conversion of  their shares  of
Brandon  Common Stock into shares of Interim  Common Stock pursuant to the terms
of the Merger  (except to  the extent  cash is  received in  lieu of  fractional
shares).  The tax basis of the shares  of Interim Common Stock into which shares
of Brandon Common  Stock are  converted pursuant  to the  Merger (including  any
fractional  shares of Interim Common Stock deemed  received) will be the same as
the tax  basis of  such Brandon  Common Stock  exchanged therefor.  The  holding
period  for shares of Interim  Common Stock into which  shares of Brandon Common
Stock are converted  pursuant to the  Merger will include  the period that  such
shares  of Brandon Common  Stock were held  by the holder,  provided such shares
were held as  a capital  asset by the  holder as  of the Effective  Time of  the
Merger.
 
    A  Brandon stockholder who  receives cash in  lieu of a  fractional share of
Interim Common Stock will be treated for  federal income tax purposes as if  the
cash  was  received  in payment  for  this  fractional share,  and  such Brandon
stockholder will  therefore  recognize gain  or  loss equal  to  the  difference
between  the cash  received and such  stockholder's tax basis  in the fractional
share.
 
    THE DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL INFORMATION ONLY.  IT
DOES  NOT ADDRESS  THE STATE, LOCAL  OR FOREIGN  TAX ASPECTS OF  THE MERGER. THE
DISCUSSION IS BASED ON CURRENTLY EXISTING  PROVISIONS OF THE CODE, EXISTING  AND
PROPOSED  TREASURY REGULATIONS THEREUNDER AND CURRENT ADMINISTRATIVE RULINGS AND
COURT DECISIONS. ALL OF THE FOREGOING ARE SUBJECT TO CHANGE AND ANY SUCH  CHANGE
COULD  AFFECT  THE  CONTINUING  VALIDITY  OF  THE  DISCUSSION.  BECAUSE  OF  THE

ACCOUNTING TREATMENT
 
    The Merger is expected  to be accounted  for using the  pooling-of-interests
method  of accounting  pursuant to Opinion  No. 16 of  the Accounting Principles
Board and interpretations thereof. In this connection, Interim Services  expects
to  receive an  opinion from Deloitte  & Touche LLP,  independent accountants to
Interim Services, to  the effect  that the  Merger will  be accounted  for as  a
pooling  of interests under the applicable accounting standards. Brandon expects
to receive from Coopers & Lybrand L.L.P., independent accountants to Brandon,  a
letter  to the effect that Coopers & Lybrand L.L.P. concurs with the conclusions
of Brandon's management that no conditions  exist with respect to Brandon  which
would  preclude accounting for the  Merger as a pooling  of interests. Under the
Merger Agreement,  it is  a condition  precedent to  the obligation  of each  of
Interim  Services and Brandon  to consummate the  Merger that each  of them will
have received reports from  Deloitte & Touche LLP  and Coopers & Lybrand  L.L.P.
regarding  qualification of the Merger as  a pooling of interests for accounting
purposes. The pooling-of-interests method of  accounting is intended to  present
as  a  single  interest two  or  more  common stockholder  interests  which were
previously independent. The pooling-of-interests method of accounting treats the
combining companies  as having  been merged  from inception.  Consequently,  the
historical  financial statements  for periods prior  to the  consummation of the
Merger will  be restated  as though  the companies  had been  combined from  the
beginning  of such periods.  SEE "CERTAIN PROVISIONS OF  THE MERGER AGREEMENT --
CONDITIONS TO  CONSUMMATION OF  THE MERGER"  AND "UNAUDITED  PRO FORMA  COMBINED
CONDENSED FINANCIAL INFORMATION."
 
    The  Merger  Agreement  prohibits  Interim Services  and  Brandon  and their
respective subsidiaries from taking or failing  to take any action which  action
or  failure such party knows  would jeopardize the treatment  of the Merger as a
pooling of interests  for accounting  purposes. SEE "CERTAIN  PROVISIONS OF  THE
MERGER AGREEMENT -- POOLING-OF-INTERESTS ACCOUNTING TREATMENT."
 
REGULATORY APPROVALS
 
    Under  the Hart-Scott-Rodino Antitrust Improvements  Act of 1976 (the "H-S-R
Act") and the rules promulgated thereunder by the Federal Trade Commission  (the
"FTC"),  the Merger may  not be consummated until  notifications have been given
and certain information has been furnished to the FTC and the Antitrust Division
of the Department of  Justice (the "Antitrust  Division") and specified  waiting
period  requirements  have been  satisfied. Interim  Services and  Brandon filed
notification and report forms under the H-S-R Act with the FTC and the Antitrust
Division in early April, 1996, and the required waiting periods for such filings
under the H-S-R  Act were terminated  on April  12, 1996. However,  at any  time
before  or after the Effective Time of  the Merger, and notwithstanding that the
H-S-R Act waiting periods have been terminated, the FTC, the Antitrust  Division
or  any state government could  take such action under  the antitrust laws as it
deems necessary or desirable in the  public interest. Such action could  include
seeking  to  enjoin the  Merger  or seeking  divestiture  of Brandon  by Interim
Services, in  whole or  in part,  or the  divestiture of  substantial assets  of
Interim Services, Brandon or their respective subsidiaries.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
    Certain  members of Brandon's management and the Brandon Board may be deemed
to have interests in the Merger in addition to their interest as stockholders of
Brandon generally, including, among other  things, the matters described  below.
The  Brandon  Board  was aware  of  these  matters when  it  approved  (with all
directors voting) the Merger Agreement.
 
    INDEMNIFICATION; INSURANCE
 
    In the Merger Agreement, Interim Services has agreed that from and after the
Effective Time,  it will  indemnify and  advance costs  and expenses  (including
legal  fees and expenses) to directors and officers of Brandon equivalent to the
indemnification   provided    or   available    under   the    Certificate    of
 
                                       40
<PAGE>
Incorporation  and By-Laws of  Brandon or to the  fullest extent permitted under
Delaware law, with respect to acts or omissions occurring prior to the Effective
Time, including without limitation the authorization of the Merger Agreement and
the transactions  contemplated thereby,  for  a period  of  six years  from  the
Effective  Time, or in the case of claims made prior to the end of such six year
period, until such claims are finally resolved.
 
    Interim Services has also agreed to provide continuing director and  officer
liability  insurance for the directors  and officers of Brandon  for a period of
six years  after the  Effective Time  with terms  and conditions  similar to  or
better  than those in  effect under Brandon's  existing directors' and officers'
insurance policy. However,  if coverage  for six  years cannot  be obtained  for
$150,000  or less, Interim Services must provide coverage for three years or for
the maximum period obtainable for $150,000, whichever is greater.
 
    EMPLOYEE BENEFIT PLANS, PROGRAMS AND ARRANGEMENTS
 
    The employee benefit  plans, arrangements  and related  policies of  Brandon
will  initially  be  unaffected by  the  Merger. Following  the  Merger, Interim
Services has  agreed to  use  reasonable efforts  to retain  Brandon's  existing
officers and full-time employees (excluding Ira Brown, Brandon's Chief Executive
Officer,  who will retire following the Merger (SEE "-- EMPLOYMENT AND CHANGE OF
CONTROL AGREEMENTS")) with levels of  aggregate total compensation (salary  plus
benefits)  substantially equivalent in  the aggregate to  those provided to such
employees  by  Brandon,  and  with  policies  substantially  equivalent  in  the
aggregate  to the employees as those  followed by Brandon. Following the Merger,
Interim Services will review Brandon's employee benefit plans, arrangements  and
policies  with  a view  towards consolidating  the  same with  Interim Services'
plans, arrangements  and policies  to the  extent feasible  and subject  to  the
immediately preceding sentence. To the extent former employees of Brandon become
participants  in a plan, arrangement or policy of Interim Services, they will be
given past service  credit for  all purposes,  and no  prior existing  condition
limitation  will be imposed with respect to any medical coverage plan of Interim
Services (except to the extent that such limitations have already been imposed).
 
    EMPLOYMENT AND CHANGE IN CONTROL AGREEMENTS
 
    Brandon entered into employment  agreements with Domenica  Schulz-Scarpulla,
Patricia  Kennedy and Robert Miano on January 25, 1996, and with Peter Lordi and
two other officers on January 31, 1996, (each such person, an "executive"). Each
agreement provides  that the  executive  will continue  in  his or  her  current
position  with  Brandon through  December 31,  1998,  unless extended  by mutual
agreement or  terminated for  good cause  (as defined  in the  agreement).  Each
agreement  contains a non-compete provision which extends for three years beyond
the term of the  agreement. The agreements require  the continuation during  the
contract  period of the executive's salary  and benefits set forth therein, with
bonuses in the discretion  of the Compensation Committee  of the Brandon  Board.
These  employment agreements are  not terminated by virtue  of either the Merger
Agreement or the Merger. The agreements provide for certain payment and benefits
to the executive in the event  the executive's employment is terminated (or  the
executive  resigns under specified  conditions following a  change in control as
defined in the agreements  (the "Change in Control  Events")). The payments  and
benefits provided are subject to reduction if they exceed levels specified under
the golden parachute provisions of the Code and for two of the four highest paid
executives  other  than Mr.  Brown such  reductions are  expected to  occur. The
Merger will  constitute a  Change in  Control Event  for the  purposes of  these
agreements.  If,  pursuant  to  the provisions  described  above,  payments were
required to be  made to  Ms. Schulz-Scarpulla, Ms.  Kennedy, Mr.  Lordi and  Mr.
Miano (the four most highly compensated executive officers of Brandon other than
Mr.  Brown as named in Brandon's most recent annual meeting proxy statement), as
of July 1, 1996 the estimated amount of such payments and benefits, taking  into
account  the  necessary reductions  would  be approximately  $715,000, $522,000,
$516,000 and  $508,000,  respectively.  The estimated  amount  of  payments  and
benefits  to all the executive  officers with change in  control agreements as a
group would be approximately $2,873,000.
 
                                       41
<PAGE>
    Brandon has an  employment agreement  with Ira  B. Brown,  its Chairman  and
Chief Executive Officer. On February 27, 1996, Brandon and Mr. Brown amended his
employment  agreement, with such amendment to take effect only upon consummation
of the Merger. The amendment provides that Mr. Brown will retire as Chairman and
Chief Executive Officer of Brandon effective as of the Closing Date, and that he
will thereafter receive  no compensation pursuant  to his employment  agreement,
although  he will  retain certain medical  benefits. Mr. Brown  will also retain
certain registration  rights under  his employment  agreement, enabling  him  to
cause Interim Services to register for resale the shares of Interim Common Stock
which  will be issued to him and  certain persons affiliated with him (including
Myra Brown, his wife  and a director  and officer of  Brandon). Because Mr.  and
Mrs.  Brown together own a substantial amount of Brandon Common Stock and may be
deemed "affiliates" of  Brandon, their  ability to  sell any  shares of  Interim
Common  Stock they receive in the Merger would be severely restricted by federal
securities laws in  the absence of  these registration rights.  Even with  these
registration rights, the Browns will be subject to certain restrictions on their
ability to sell their shares of Interim Common Stock they receive in the Merger.
SEE  "-- RESALE CONSIDERATIONS WITH RESPECT TO THE INTERIM COMMON STOCK," below.
Mr. and Mrs. Brown have informed Brandon and Interim Services that they have  no
present  intention to  sell the  shares of Interim  Common Stock  that they will
receive in the Merger.
 
    Interim Services expects to continue the employment of all Brandon  officers
after  the Merger under the terms  and conditions of the employment arrangements
presently in effect between Brandon and its officers.
 
    STOCK OPTIONS
 
    Each Brandon  director and  executive officer  holds Brandon  Stock  Options
which,  upon the Effective Time  of the Merger, will  automatically vest, to the
extent not yet vested, and become exercisable for shares of Interim Common Stock
rather than shares of Brandon Common Stock at a ratio of 0.88 shares of  Interim
Common Stock for each share of Brandon Common Stock covered by the Brandon Stock
Options,  subject  to  certain  anti-dilution adjustments.  SEE  "THE  MERGER --
TREATMENT OF OPTIONS."
 
OPERATIONS AFTER THE MERGER
 
    Upon consummation  of the  Merger, Brandon  will operate  as a  wholly-owned
subsidiary  of Interim Services.  Following the Merger,  the President and Chief
Operating Officer of Brandon  will continue to manage  the business of  Brandon,
reporting  to the Interim Services  Executive Vice President, Operations. Except
for Ira B. Brown,  Brandon's Chief Executive Officer  who will retire  following
the Merger, other officers and management of Brandon are expected to continue in
their prior roles.
 
    Pursuant  to the Merger Agreement, Brandon  has the right to select, subject
to Interim Services' approval which will not be unreasonably withheld, a  person
who  will be appointed  by the Interim Board  to serve as  a director of Interim
Services and  who will,  subject to  the requirements  of the  Delaware  General
Corporation  Law, be included within a class of Interim Services directors whose
three-year term expires at the  Annual Meeting of Interim Services  stockholders
to  be held in 1999. Such person will be  one of the directors of Brandon at the
time of the Merger but will not be  any of the persons who will be employees  of
the Surviving Corporation following the Effective Time.
 
RESALE CONSIDERATIONS WITH RESPECT TO THE INTERIM COMMON STOCK
 
    The  shares of  Interim Common Stock  that will  be issued if  the Merger is
consummated have been  registered under the  Securities Act and  will be  freely
transferable, except for shares received by any persons, including directors and
executive  officers of Brandon, who may be  deemed to be "affiliates" of Brandon
under Rule 145 promulgated under the Securities Act. An "affiliate" of an issuer
is defined generally as a person who "controls" the issuer. Directors, executive
officers and 10%  stockholders are  presumed by  the Commission  to control  the
issuer.  Affiliates may not  sell their shares of  Interim Common Stock acquired
pursuant to the Merger, except  pursuant to an effective registration  statement
under the Securities Act covering the Interim Common Stock or in compliance with
Rule  145 or another applicable exemption  from the registration requirements of
the Securities Act.
 
                                       42
<PAGE>
    Persons who  may be  deemed to  be "affiliates"  of Brandon  have  delivered
letters to Interim Services in which they have agreed to certain restrictions on
their ability to sell, transfer or otherwise dispose of ("transfer") any Brandon
Common  Stock owned by them and any Interim Common Stock acquired by them in the
Merger. Pursuant to the accounting rules governing a pooling of interests, these
individuals have agreed not to transfer  the shares commencing 30 days prior  to
the  Effective Time and ending when financial  results covering at least 30 days
of post-merger combined  operations of  Interim Services and  Brandon have  been
published  by Interim  Services or filed  by Interim  Services on a  Form 8-K or
10-Q. Also, in connection with the pooling-of-interests rules, these individuals
have agreed not to transfer their Brandon Common Stock in the period prior to 30
days before the Effective  Time without giving  Interim Services advance  notice
and   an  opportunity   to  object   if  the   transfer  would   interfere  with
pooling-of-interests accounting  for the  Merger. Pursuant  to Rule  145,  these
individuals  have also agreed to refrain  from transferring Interim Common Stock
acquired by them in the Merger,  except in compliance with certain  restrictions
imposed by Rule 145.
 
    Persons,  who  may  be deemed  "affiliates"  of Interim  Services  have also
delivered letters in which they have agreed not to transfer Interim Common Stock
beneficially owned by them in violation of the pooling-of-interests restrictions
set forth above with respect to Brandon.
 
                   CERTAIN PROVISIONS OF THE MERGER AGREEMENT
 
    The following  is  a  summary  of the  material  provisions  of  the  Merger
Agreement  not  summarized  elsewhere in  this  Proxy  Statement/Prospectus. The
Merger Agreement is attached as Exhibit A to this Proxy Statement/Prospectus and
is incorporated herein by reference. THE  FOLLOWING SUMMARY IS QUALIFIED IN  ITS
ENTIRETY BY REFERENCE TO THE MERGER AGREEMENT.
 
EXCHANGE PROCEDURES
 
    As soon as reasonably practicable after the Effective Time, Interim Services
will  instruct  Chemical  Mellon  Shareholder  Services,  L.L.C.  (the "Exchange
Agent") to mail to each holder of record of certificates which immediately prior
to the Effective Time evidenced outstanding shares of Brandon Common Stock  (the
"Certificates"):  (i) a letter of transmittal  (which will specify that delivery
shall be effected, and  risk of loss  and title to  the Certificates will  pass,
only  upon proper delivery  of the Certificates  to and receipt  by the Exchange
Agent) and  (ii)  instructions  for  use  in  effecting  the  surrender  of  the
Certificates  in exchange for  certificates evidencing shares  of Interim Common
Stock. Upon surrender of  a Certificate for cancellation  to the Exchange  Agent
together  with  such  letter  of  transmittal,  duly  executed,  and  such other
customary documents as may be required pursuant to such instructions, the holder
of such  Certificate  will be  entitled  to  receive in  exchange  therefor  (A)
certificates  evidencing that  number of  whole shares  of Interim  Common Stock
which such holder has the right to  receive in respect of the shares of  Brandon
Common  Stock  formerly  evidenced by  such  Certificate,  (B) cash  in  lieu of
fractional shares of Interim Common Stock  to which such holder may be  entitled
and  (C) any dividends or  other distributions to which  such holder is entitled
(the "Merger Consideration"). The Certificates so surrendered will be cancelled.
 
    In the event of a  transfer of ownership of  shares of Brandon Common  Stock
which  is  not registered  in  the transfer  records  of Brandon,  a certificate
evidencing the proper number of shares of Interim Common Stock may be issued  to
a  transferee if the Certificate evidencing  such shares of Brandon Common Stock
is presented to  the Exchange Agent,  accompanied by all  documents required  to
evidence  and effect  such transfer  and by  evidence that  any applicable stock
transfer taxes  have been  paid. In  the event  any Certificate  has been  lost,
stolen  or  destroyed, upon  the making  of an  affidavit of  that fact  and, if
required by Interim Services or the  Exchange Agent, the posting by such  person
of  a bond in such amount as the  Exchange Agent may direct as indemnity against
any claim that  may be made  against it  with respect to  such Certificate,  the
Exchange   Agent  will  issue  in  exchange  for  such  lost,  stolen  destroyed
Certificate the Merger Consideration deliverable in respect thereof pursuant  to
the  Merger Agreement. Until surrendered, each Certificate will be deemed at any
time after the Effective Time  to evidence only the  right to receive upon  such
surrender the Merger Consideration.

and that of its subsidiaries intact, (ii) keep available the present services of
its  employees and those of its subsidiaries  and (iii) preserve the goodwill of
its customers and employees and those  of its subsidiaries and others with  whom

    Brandon  agreed that from the date of  the Merger Agreement to the Effective
Time, except  as  otherwise  approved  by Interim  Services  in  writing  or  as

NO SOLICITATION OF TRANSACTIONS
 
    In  the  Merger Agreement  Brandon has  agreed that  it and  its affiliates,
employees,  representatives,  financial   advisors  and  agents   (collectively,
"Brandon  Related Parties") will cease all existing discussions or negotiations,
if any, with any parties (other than Interim Services) conducted with respect to
any merger, acquisition or exchange of all or any material portion of the assets
of, or  any equity  interest  in, Brandon  or any  of  its subsidiaries  or  any
business  combination with  Brandon or  any of  its Subsidiaries  or any similar
transaction. (Any such transaction with a  party other than Interim Services  or
any  affiliate, associate or designee of  Interim Services is referred to herein
as an  "Acquisition Transaction"  and any  proposal relating  to an  Acquisition
Transaction  is referred to herein  as an "Acquisition Proposal.") Additionally,
Brandon has  agreed  that neither  it  nor  any Brandon  Related  Parties  will,
directly   or  indirectly,  encourage,  solicit,   participate  in  or  initiate
discussions  or  negotiations   with,  or  provide   any  information  to,   any
corporation,  partnership, person or  other entity or  group (other than Interim
Services or any affiliate, associate or designee of Interim Services) concerning
any Acquisition Transaction or Acquisition Proposal.
 
    However, Brandon may enter into discussions or negotiations with or  provide
information to a third party in connection with an Acquisition Proposal provided
that the Brandon Board, upon advice of outside counsel, determines in good faith
that  the exercise  of its  fiduciary duties  requires that  such discussions or
negotiations must be commenced or such  information should be provided. In  such
case,  Brandon has agreed to communicate  promptly to Interim Services the terms
of any Acquisition Proposal, whether written or oral, which it receives and what
response, if any, the Brandon Board has determined is necessary or  appropriate.
Subject  to  any  confidentiality agreement  with  any such  third  party (which
Brandon, based  upon advice  of outside  counsel, determines  in good  faith  is
required  to be executed in order for its  Board of Directors to comply with its
fiduciary duties, but which  Brandon agrees will be  on terms not  substantially
different  from  the  confidentiality  agreement  between  Interim  Services and
Brandon regarding the Merger),  Brandon will keep  Interim Services informed  of
the status of any such discussions or negotiations.
 
POOLING-OF-INTERESTS ACCOUNTING TREATMENT
 
    In the Merger Agreement, Interim Services and Brandon have agreed that, from
February  27, 1996,  the date  of the Merger  Agreement, to  the Effective Time,
neither Interim Services nor Brandon will take or fail to take any action  which
action  or failure they know  would jeopardize the treatment  of the Merger as a
pooling of interests for accounting purposes.
 
CONDITIONS TO CONSUMMATION OF THE MERGER
 
    The respective  obligations  of each  party  to consummate  the  Merger  are
subject  to the satisfaction, or, where  legally permissible, waiver at or prior
to the Effective Time of the following conditions: (a) the Merger Agreement  and
the  transactions contemplated by the Merger  Agreement shall have been approved
by the  requisite vote  of the  stockholders of  Brandon; (b)  the  Registration
Statement  shall have been declared effective by the Commission and shall not be
subject to  a stop  order or  any threatened  stop order,  and the  issuance  of
Interim  Common  Stock  shall have  been  qualified  in every  state  where such
qualification is required under  the applicable state  securities laws; (c)  all
necessary   regulatory  or  governmental  approvals  and  consents  required  to
consummate the transactions  contemplated by  the Merger  Agreement (other  than
immaterial  government permits)  shall have  been obtained  without any  term or
condition  which  would  materially  impair   the  value  of  Brandon  and   its
subsidiaries,  taken as a whole,  or which would materially  impair the value of
Interim Services and  its subsidiaries,  taken as  a whole,  and all  conditions
required  to  be satisfied  prior to  the Effective  Time by  the terms  of such
approvals and  consents shall  have  been satisfied  and all  statutory  waiting
periods  in respect thereof shall have expired; (d) no order, judgment or decree
shall be outstanding against a  party to the Merger  Agreement or a third  party
that  would have  the effect  of preventing completion  of the  Merger; no suit,
action or other proceeding  shall be pending or  threatened by any  governmental
body  in which  it is  sought to restrain  or prohibit  the Merger  and no suit,
action or other  proceeding shall be  pending before any  court or  governmental
agency  in which it is sought to restrain or prohibit the Merger or obtain other
substantial monetary  or  other  relief  against one  or  more  parties  to  the
 
                                       46
<PAGE>
Merger  Agreement  in connection  with the  Merger  Agreement and  which Interim
Services or Brandon  determines in good  faith, based upon  the advice of  their
respective  counsel, makes it inadvisable to proceed with the Merger because any
such suit, action or  proceeding has a significant  potential to be resolved  in
such  a  way as  to deprive  the party  electing not  to proceed  of any  of the
material benefits to  it of the  Merger; (e) Interim  Services and Brandon  each
shall  have received an opinion of Bryan  Cave LLP, counsel to Interim Services,
that for federal and  state income tax  purposes, the Merger  will qualify as  a
tax-free reorganization under Section 368(a) of the Code, and except with regard
to cash received in exchange for fractional shares, that no gain or loss will be
recognized  by the holders of Brandon Common Stock in exchanging their shares of
Brandon Common Stock  for Interim  Common Stock;  and (f)  Interim Services  and
Brandon  shall each have received reports of Deloitte & Touche LLP and Coopers &
Lybrand L.L.P., in form and substance reasonably acceptable to such party, based
on such  procedures as  were  deemed relevant,  regarding qualification  of  the
Merger as a pooling of interests under generally accepted accounting principles.
 
    The  obligations of Interim  Services and Merger Sub  are further subject to
the satisfaction or waiver, at or prior to the Effective Time, of the  following
conditions:  (a)  generally,  the  representations  and  warranties  of  Brandon
contained in the  Merger Agreement  shall be true  and correct  in all  material
respects  on the Closing Date as  though made on and as  of the Closing Date and
Brandon shall have performed in all material respects the agreements,  covenants
and  obligations to be  performed by it  prior to the  Closing Date; (b) Interim
Services shall have received an opinion of Pitney, Hardin, Kipp & Szuch, counsel
to  Brandon,  dated  the  Closing   Date,  in  form  and  substance   reasonably
satisfactory  to  Interim Services;  (c)  Brandon shall  have  furnished Interim
Services with such certificates of its  officers or other documents to  evidence
fulfillment  of  the closing  conditions set  forth in  the Merger  Agreement as
Interim Services  may  reasonably request;  (d)  the Merger  Agreement  and  the
transactions contemplated thereby shall have been approved by the requisite vote
of  the stockholders  of Interim Services;  and (e) Interim  Services shall have
received a  fairness opinion  from  DLJ, which  shall  not have  been  adversely
modified or withdrawn prior to the Closing.
 
    The  obligations  of  Brandon are  further  subject to  the  satisfaction or
waiver, at or  prior to  the Effective Time,  of the  following conditions:  (a)
generally, the representations and warranties of Interim Services and Merger Sub
contained  in the  Merger Agreement  shall be true  and correct  in all material
respects on the Closing Date  as though made on and  as of the Closing Date  and
Interim  Services shall have performed in all material respects, the agreements,
covenants and obligations to be performed by  it prior to the Closing Date;  (b)
Brandon  shall have received an opinion  of outside counsel to Interim Services,
dated the  Closing  Date,  in  form and  substance  reasonably  satisfactory  to
Brandon;  (c) Brandon shall have received a fairness opinion from Goldman Sachs,
dated on or shortly prior to  the date of the Proxy Statement/Prospectus,  which
shall  not  have been  adversely  modified or  withdrawn  prior to  Closing; (d)
Brandon shall select, subject to Interim  Services' approval which shall not  be
unreasonably withheld, a person who shall be duly appointed by the Interim Board
to  serve  as a  director  of Interim  Services and  who  shall, subject  to the
requirements of the  Delaware General  Corporation Law, be  included within  the
class  of Interim Services directors whose three-year terms begin at the Interim
Special Meeting  (and such  person shall  be  one of  the current  directors  of
Brandon  but  shall not  be any  of the  persons  who will  be employees  of the
Surviving Corporation  following the  Effective Time);  (e) Brandon  shall  have
received  evidence, reasonably satisfactory  to it, that  Interim Services shall
have obtained certain insurance covering directors and officers of Brandon  with
respect  to certain liabilities;  and (f) Interim Services  and Merger Sub shall
have furnished Brandon with such certificates of its officers or others and such
other documents to evidence fulfillment of  the closing conditions set forth  in
the Merger Agreement as Brandon may reasonably request.
 
TERMINATION; TERMINATION FEE
 
    The  Merger Agreement may be terminated prior to the Effective Time, whether
before or after approval of the Merger Agreement by the stockholders of  Brandon
or  by the  stockholders of  Interim Services,  only as  follows: (a)  by mutual
written consent  of Interim  Services, Merger  Sub and  Brandon; (b)  by  either
Interim Services or Brandon if (i) the Effective Time shall not have occurred on
or prior
 
                                       47
<PAGE>
to  August 31, 1996 unless the failure is  due to a failure of the party seeking
to terminate  to perform  or observe  its  agreements set  forth in  the  Merger
Agreement, (ii) the stockholders of either Interim or Brandon vote upon and fail
to  approve the Merger  Agreement, (iii) upon  written notice to  the other, any
application for regulatory or governmental approval necessary to consummate  the
Merger  is  denied  or withdrawn  or  is  approved with  conditions  which would
materially impair  the value  of the  other with  its subsidiaries,  taken as  a
whole, despite the reasonable efforts of the party seeking to terminate to avoid
such  result, (iv) there was a  material breach in any representation, warranty,
covenant, agreement or obligation of the other in the Merger Agreement and  such
breach (provided it is curable and the other party promptly commences its effort
to  cure) shall not have been remedied within 30 days after receipt by the other
of notice in writing specifying the nature of such breach and requesting that it
be remedied, (v) the Board of Directors  of the other party has not  recommended
the  Merger  to  its stockholders  in  this Proxy  Statement/Prospectus,  or has
modified or rescinded its  recommendation of the Merger  to its stockholders  as
being  advisable and fair to  and in the best interests  of such other party and
its stockholders,  or has  modified  or rescinded  its  approval of  the  Merger
Agreement, or has resolved to do any of the foregoing, or (vi) the conditions to
its obligations to close set forth in the Merger Agreement are not satisfied and
are  not capable of being satisfied by  August 31, 1996; (c) by Interim Services
if (i) there shall have occurred  a material adverse change from that  disclosed
in  Brandon's Annual Report on Form 10-K for  the year ended October 1, 1995, or
(ii) Brandon  shall  have entered  into  a definitive  agreement  contemplating,
announced  or approved an Acquisition Transaction;  (d) by Brandon, if (i) there
shall have occurred  a material adverse  change from that  disclosed in  Interim
Services'  Quarterly Report on Form 10-Q for the nine months ended September 29,
1995,  (ii)  the  Brandon  Board   has  entered  into  a  definitive   agreement
contemplating,   announced   or  approved   an  Acquisition   Transaction  after
determining, in  good  faith and  upon  advice  of outside  counsel,  that  such
approval  was necessary in the exercise of its fiduciary duties under applicable
laws, or (iii) if the average of the ten closing prices of Interim Common  Stock
during  the first ten  of the 13 consecutive  trading days immediately preceding
the date of the Brandon Special Meeting is less than $33.00.
 
    If: (x) Brandon terminates the Merger  Agreement pursuant to (d)(ii) in  the
immediately  preceding paragraph, or (y)  Interim Services terminates the Merger
Agreement pursuant to (b)(v) in the immediately preceding paragraph and  Brandon
enters  into  a definitive  agreement  contemplating, announces  or  approves an
Acquisition Transaction within one year after the date of the Merger  Agreement,
or  (z) Interim Services terminates the  Merger Agreement pursuant to (c)(ii) in
the immediately preceding paragraph, then Brandon has agreed to immediately (but
in any event within  three business days)  pay to Interim  Services, in cash,  a
termination  fee  equal to  $1.5  million, which  amount  the parties  agree and
acknowledge is sufficient to cover  all reasonable out-of-pocket expenses  which
Interim  Services  may incur  in connection  with the  Merger Agreement  and the
Merger. The obligation of Brandon to pay a $1.5 million fee to Interim  Services
under  such  circumstances  may be  considered  a deterrent  to  other potential
acquisitions of control of Brandon, as it is likely to increase the cost of such
an acquisition to any party other than Interim Services.
 
EXPENSES
 
    Except as stated below, all costs  and expenses incurred in connection  with
the Merger Agreement and the transactions contemplated thereby (including legal,
accounting and investment banking fees and expenses) shall be borne by the party
incurring such costs and expenses. Interim Services and Brandon have each agreed
to  pay  50% of  all expenses  and fees  related to  filing of  the Registration
Statement (including this Proxy Statement/Prospectus) and related documents with
the Commission and filings pursuant to state "blue sky" laws and regulations  in
connection with the Merger.
 
    Notwithstanding  anything else  in the Merger  Agreement, in  the event that
either Interim Services or  Brandon shall willfully  default in its  obligations
under  the  Merger Agreement,  the non-defaulting  party  may pursue  any remedy
available at law or  in equity to enforce  its rights and shall  be paid by  the
willfully  defaulting  party  for  all damages,  costs  and  expenses, including
without limitation
 
                                       48
<PAGE>
reasonable legal,  reasonable  accounting,  reasonable  investment  banking  and
reasonable  printing expenses, incurred or  suffered by the non-defaulting party
in connection with  the Merger  Agreement or in  the enforcement  of its  rights
thereunder.
 
AMENDMENT AND WAIVER
 
    The  Merger Agreement  may be  amended by  Interim Services,  Merger Sub and
Brandon, at any  time prior  to or  after approval  and adoption  of the  Merger
Agreement  by  the  stockholders  of Brandon  or  approval  by  Interim Services
stockholders of the  issuance of Interim  Common Stock pursuant  to the  Merger.
However,  after any such approval, no amendment  shall be made which reduces the
amount or  changes  the  form  of  the consideration  to  be  delivered  to  the
stockholders  of  Brandon  or  adversely  affects  the  stockholders  of Interim
Services, without the approval of the affected stockholders.
 
    The parties may, at any time prior to the Effective Time of the Merger,  (i)
extend  the time for the performance of any  of the obligations or other acts of
the other parties to  the Merger Agreement; (ii)  waive any inaccuracies in  the
representations  and  warranties contained  in the  Merger  Agreement or  in any
document delivered pursuant thereto; or (iii)  waive compliance with any of  the
agreements  or conditions contained in the  Merger Agreement; provided that such
extension or waiver is in writing signed  on behalf of such party against  which
the waiver is sought to be enforced.

                INFORMATION REGARDING FORWARD LOOKING STATEMENTS
 
    Certain  statements contained  in this Proxy  Statement/Prospectus which are
not statements of current  fact may be "forward  looking statements" within  the
meaning  of Section 27A of  the Securities Act of  1993, as amended, and Section
21E of  the  Securities Exchange  Act  of  1934, as  amended.  Although  Interim
Services  and Brandon  believe that their  expectations are  based on reasonable
assumptions, they  can give  no assurance  that their  goals will  be  achieved.
Important  factors that  could cause  actual results  to differ  materially from
those in  the forward  looking statements  herein include  those factors  listed
under "Risk Factors" included elsewhere herein.

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL INFORMATION
 
    The  following unaudited pro forma  combined condensed financial information
of  Interim  Services  and  Brandon  give   effect  to  the  Merger  using   the
pooling-of-interests method of accounting and reflect the Exchange Ratio and the
pro  forma adjustments described in the accompanying notes. The accompanying pro
forma statements  of income  reflect the  Merger as  though consummated  at  the
beginning  of the periods reported and  the pro forma combined condensed balance
sheet reflects the Merger as though consummated on December 29, 1995.
 
    The consolidated financial information of  Interim Services set forth as  of
December  29, 1995 and for each of the  three years in the period ended December
29, 1995, are derived from, and are qualified by reference to, Interim Services'
audited consolidated  financial  statements  and related  notes  thereto,  which
together  with  the  related  report  of  Deloitte  &  Touche  LLP,  independent
accountants, are included in  Interim Services' Annual Report  on Form 10-K  for
the  fiscal year ended December  29, 1995 which is  incorporated by reference in
this Proxy Statement/Prospectus.
 
    Brandon's fiscal year ends on the Sunday nearest to the end of the month  of
September. Accordingly, Brandon has prepared historical financial statements and
related  notes thereto as  of October 1, 1995  and for each  of the three fiscal
years in  the  period  ended  October  1,  1995.  These  consolidated  financial
statements of Brandon have been audited by Coopers & Lybrand L.L.P., independent
accountants. The historical consolidated statement of income data of Brandon for
the fiscal years ended December 31, 1995, January 1, 1995 and January 2, 1994 is
unaudited  and  has been  derived from  the  audited consolidated  statements of
income of  Brandon by  subtracting  the results  of  operations as  reported  in
Brandon's  Quarterly  Reports  on  Form  10-Q  for  the  first  quarter  of each
respective fiscal  year and  adding the  results of  operations as  reported  in
Brandon's Quarterly Reports on Form 10-Q for the first quarter of the subsequent
respective  fiscal  year.  The  historical consolidated  balance  sheet  data of
Brandon as  of December  31,  1995 is  unaudited  and represents  the  financial
position  of Brandon as reported in Brandon's  Quarterly Report on Form 10-Q for
the fiscal quarter ended December 31, 1995.
 
    The following unaudited pro  forma combined condensed financial  information
should  be read in conjunction with  the audited financial statements, including
the notes thereto,  of Interim  Services that  are in  Interim Services'  Annual
Report  on Form 10-K incorporated herein by reference and of Brandon that are in
Brandon's Annual Report on  Form 10-K incorporated herein  by reference, and  in
conjunction  with  the  unaudited  financial  statements,  including  the  notes
thereto, of Brandon that are contained in Brandon's Report on Form 10-Q for  the
fiscal  quarter  ended  December  31,  1995,  which  report  is  incorporated by
reference in this Proxy Statement/Prospectus.
 
    During  1995,   Interim   Services  made   significant   acquisitions   (the
"Acquisitions")   which  were  accounted  for   under  the  purchase  method  of
accounting. Accordingly, Interim Services' results  for the year ended  December
29,  1995 have been adjusted to reflect the Acquisitions as though they occurred
at the beginning of 1995, but are not necessarily indicative of future operating
results or financial position.
 
    The following pro forma information  is presented for illustrative  purposes
only  and is  not necessarily indicative  of the operating  results or financial
position that would have occurred if the Merger had been consummated, nor is  it
necessarily  indicative of future  operating results or  financial position. The
unaudited pro  forma financial  information  does not  include any  expenses  or
restructuring  charges  related  to  the  Merger.  Total  Merger-related  direct
expenses are expected to  approximate $4.5 million.  In addition, the  unaudited
pro  forma financial information excludes  any potential benefits from synergies
that may result  from the Merger.  There were no  material transactions  between
Interim Services and Brandon during any of the periods presented.

     NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL INFORMATION
 
                    (AMOUNT IN THOUSANDS, EXCEPT SHARE DATA)
 
  (1) Represents  the adjustment to reflect the results of the Acquisitions made
      by Interim Services in the fiscal year ended December 29, 1995, as if  the
      Acquisitions occurred as of the beginning of the year.
 
  (2) Reclassification  of  royalties  as  a  result  of  repurchase  of Interim
      Services franchises.
 
  (3) Adjustment to reflect  additional amortization of  goodwill on a  straight
      line  basis over an average of 36  years for the Acquisitions described in
      Note 1.
 
  (4) Pro forma effect of interest charges on additional borrowings used to fund
      the Acquisitions on Interim Services'  lines of credit. Interest on  these
      facilities  is computed,  at Interim Services'  option at  either a bank's
      base rate or LIBOR, plus the applicable margin. Based on these  borrowings
      a  0.125%  increase  in  LIBOR  would  increase  annual  interest  expense
      approximately $125.
 
  (5) To record aggregate tax effect of the pro forma adjustments.
 
  (6) The weighted average shares outstanding have been adjusted to reflect  the
      conversion  of Brandon  Common Stock  into 0.88  shares of  Interim Common
      Stock.
 
  (7) Pro forma per  share amounts  are based  on historical  per share  amounts
      after  giving effect  to the pro  forma adjustments  described herein, and
      converting each share of Brandon Common Stock into 0.88 shares of  Interim
      Common Stock.
 
  (8) Prior  to its January 27, 1994  IPO, Interim Services' working capital and
      acquisition financing were provided by its former parent, H&R Block,  Inc.
      ("Block").  Effective September  25, 1993, Block  formalized its financing
      arrangement by (i) providing a revolving credit facility in the amount  of
      $20,000   to  fund  operating  requirements   of  Interim  Services;  (ii)
      converting $30,000 of  intercompany indebtedness  on such date  to a  term
      loan,  and (iii) contributing $51,289 to  the capital of Interim Services.
      The consolidated statement of income data for the year ended December  24,
      1993  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.
 
  (9) The  Unaudited  Pro Forma  Combined Condensed  Balance Sheet  reflects the
      conversion of  Brandon  Common Stock  into  Interim Common  Stock  at  the
      Exchange Ratio as provided by the Merger Agreement.
 
 (10) On  October 26, 1995, Brandon repurchased 100,000 shares of Brandon Common
      Stock for $1,805. These shares will be cancelled as of the Effective  Time
      of the Merger per the Merger Agreement.

                       COMPARATIVE RIGHTS OF STOCKHOLDERS
 
    As  a  result  of  the  Merger,  the  stockholders  of  Brandon  will become
stockholders  of  Interim  Services.  Both  Brandon  and  Interim  Services  are
corporations  incorporated under the laws of the State of Delaware. The Delaware
General  Corporation  Law  ("DGCL")  is  the  statute  which  governs   Delaware
corporations.  The following  discussion is  intended only  to highlight certain
differences  between  the  rights  of  corporate  stockholders  of  Brandon  and
corporate  stockholders of  Interim Services. These  differences arise primarily
from differences between the Brandon  Certificate of Incorporation, as  restated
and  amended (the  "Brandon Certificate"), and  the Brandon  By-laws and Interim
Services' Certificate of  Incorporation, as restated  and amended (the  "Interim
Certificate"),  and the Interim  Services By-laws, the  governing instruments of
the two companies. This discussion is not and does not purport to be complete or
to identify all differences that may,  under given fact situations, be  material
to  stockholders. For a definitive treatment of the subject matter, stockholders
of Brandon are  referred to  the Certificate  of Incorporations  and By-laws  of
Brandon  and  Interim  Services  which  are on  file  with  the  Commission. SEE
"AVAILABLE INFORMATION."
 
SIZE AND CLASSIFICATION OF DIRECTORS
 
    The Brandon Certificate and Brandon  By-laws provide that the Brandon  Board
shall  be comprised  of not  less than  three nor  more than  twelve members, as
determined by the Brandon Board. As is permitted by the DGCL, the Brandon  Board
is classified into three classes which are to be as nearly equal in number as is
possible.  The number of directors  assigned to each class  is determined by the
Brandon Board prior  to the election  of a particular  class. Directors in  each
class  serve for a  term of three  years. Elections are  staggered such that one
class is elected each year.
 
    The Interim Certificate and Interim Services By-laws provide that the number
of directors to constitute the Interim Board  shall be the number as fixed by  a
resolution  adopted  by the  holders  of a  majority  of the  outstanding shares
entitled to vote thereon  or by a  majority of the whole  Interim Board, but  is
fixed  at nine until  otherwise determined. Like the  Brandon Board, the Interim
Board is  classified  into three  classes,  and  the directors  are  elected  in
staggered terms.
 
REMOVAL OF DIRECTORS
 
    The Brandon Certificate and By-laws provide that any director may be removed
with  or without cause, but in the latter case only upon the affirmative vote of
the holders of  two-thirds of  all classes  of stock  then entitled  to vote  in
elections  of  directors. Likewise,  the Interim  Certificate provides  that any
director may be removed  at any time,  but only by the  affirmative vote of  the
holders  of two-thirds or more of the  outstanding shares of each class of stock
entitled to elect one or more directors at a meeting of the stockholders  called
for such purpose.
 
STOCKHOLDER MEETINGS
 
    Under  the Brandon By-laws, annual meetings  of stockholders will be held on
such date, time and place as may be  designated by the Brandon Board, or on  the
second  Tuesday in January of each year if no designation is made. A stockholder
who wants to present a proposal or nominate a person for election as director at
any meeting must  give notice thereof  to the Secretary  at Brandon's  principal
executive office not less than 60 nor more than 90 days prior to the date of the
meeting,  unless the date  of the meeting  is first announced  or disclosed less
than 70 days  prior to the  date of the  meeting, in which  case notice must  be
given  not more  than ten  days after the  date the  meeting is  so announced or
disclosed. Such stockholder notice regarding  a proposal must be accompanied  by
the  text of  the proposal, a  brief written  statement of the  reasons why such
stockholder favors the  proposal and  setting forth  the name  and address,  the
number  and class of all  shares of each class  of stock of Brandon beneficially
owned by such stockholder and any  material interest of such stockholder in  the
proposal.  Any  stockholder notice  regarding a  nomination of  any person  as a
director must be accompanied by a statement in writing setting forth the name of
the person to be nominated, the number and class of all shares of each class  of
stock  of  the  Brandon  beneficially  owned  by  such  person,  the information
regarding such person required  by paragraphs (a),  (e) and (f)  of Item 401  of
Regulation S-K adopted by
 
                                       57
<PAGE>
the  Commission, such person's signed consent to  serve as a director of Brandon
if elected, such stockholder's name and address and the number and class of  all
shares of each class of stock beneficially owned by such stockholder.
 
    The  Interim  Services  By-laws  provide  that  the  annual  meeting  of the
stockholders will be held on the second Thursday of May of each year at  Interim
Services' office in Fort Lauderdale, Florida, or at such other time and place as
may  be designated  by the  Interim Board.  The stockholder  notice necessary to
present a proposal or  nominate a person for  election as director differs  from
that required by the Brandon By-laws in that the stockholder must give notice to
the  Secretary not less than 50 days nor more than 75 days prior to the meeting,
unless fewer than 65 days' notice or prior public disclosure of the date of  the
meeting  is  given or  made to  the stockholders,  in which  case notice  by the
stockholder must be given not later than  the close of business on the 15th  day
following  the day on which such notice  or public disclosure of the meeting was
made. The information required to be presented in a stockholder notice regarding
a proposal is essentially the same as that required of a stockholder of Brandon.
However, the Interim Services By-laws do not specifically state the requirements
for the contents of a stockholder notice regarding the nomination of a person as
a director.
 
ACTION BY CONSENT OF STOCKHOLDERS
 
    Pursuant to the Brandon Certificate, any action required or permitted to  be
taken  at an annual or special meeting of the stockholders must be taken only at
such meeting and may not be taken by the written consent of the stockholders  in
lieu of a meeting.
 
    Since Interim Common Stock is registered under the Exchange Act, as amended,
like Brandon, any action taken at such annual or special meeting of stockholders
must  be taken  at such  meeting and  a written  consent of  stockholders is not
allowed. However, if for any reason, Interim  Services no longer has a class  of
stock  registered under the Exchange Act, unlike Brandon, any action required to
be taken at any annual or special  meeting of the stockholders would be  allowed
to  be taken  without a meeting,  without prior  notice, and without  a vote, if
consent in writing setting forth  the action taken is  signed by the holders  of
outstanding stock having not less than the minimum number of votes that would be
necessary  to authorize  or take such  action at  a meeting at  which all shares
entitled to vote thereon were present and voted.
 
PREEMPTIVE RIGHTS
 
    Delaware  law  does  not  provide   for  preemptive  rights  to  acquire   a
corporation's  unissued stock. However,  such right may  be expressly granted to
the stockholders in the corporation's certificate of incorporation. Neither  the
Brandon Certificate nor the Interim Certificate provides for preemptive rights.
 
AMENDMENTS TO CERTIFICATE AND BY-LAWS
 
    The Brandon Certificate and By-laws may be amended, altered or repealed from
time  to time  by a stockholder  vote; provided,  however, that the  vote of the
holders of two-thirds of all classes of  stock entitled to vote in elections  of
directors  is required to amend, alter, change  or repeal the following: (1) the
provision in the Brandon  Certificate addressing the  procedures for removal  of
directors;  (2) the  provision in the  Brandon Certificate  precluding action by
written consent of the stockholders in lieu of a meeting, and addressing who may
call a stockholder meeting; (3) the provision in the Brandon Certificate stating
the  requisite  votes   necessary  in  order   to  authorize  various   business
combinations  and transfers of  assets and capital stock  and dissolution of the
corporation; (4) the provision in the Brandon Certificate addressing the  number
and election of directors and classes of directors; and (5) the provision in the
Brandon  Certificate  addressing  the  rights  and  preferences  of  the Brandon
Preferred Stock.
 
    Like Brandon, Interim Services requires a two-thirds vote to amend, alter or
repeal the provision  addressing the number  and election of  directors and  the
procedures  for removal of directors.  However, unlike Brandon, Interim Services
also requires  such two-thirds  vote  to amend  alter  or repeal  the  following
provisions  in the  Interim Certificate  and By-laws:  (1) any  provision in the
Interim Services
 
                                       58
<PAGE>
By-laws;  (2)  the   provision  in  the   Interim  Certificate  addressing   the
corporation's  authorized capital stock  including the respective  rights of the
holders thereof; and (3) the provision describing the procedures for calling and
conducting special meetings of the stockholders.
 
BUSINESS COMBINATIONS
 
    Except as  described  below, to  effectuate  a "Business  Combination,"  the
Brandon  Certificate requires the affirmative  vote of both (i)  at least 80% of
the votes  entitled to  be  cast, and  (ii) at  least  two-thirds of  the  votes
entitled  to be cast, excluding shares owned by an "Interested Stockholder." The
Brandon Certificate defines "Interested  Stockholder" as any  person who (i)  is
the  beneficial owner of at least 10% of  the votes entitled to be cast, or (ii)
is an affiliate  or associate of  Brandon and  at any time  within the  two-year
period immediately prior to the date in question, was the beneficial owner of at
least  10% of the votes entitled to be cast. "Business Combination" is generally
defined in the Brandon Certificate as  follows: (1) any merger or  consolidation
of  Brandon with an Interested Stockholder; (2) any disposition of securities or
assets of Brandon with or for the benefit of an Interested Stockholder having an
aggregate value of  more than 5%  of the  book value of  the total  consolidated
assets  of Brandon or more  than 5% of the stockholders  equity of the entity in
question; (3)  the  adoption  of a  plan  or  proposal for  the  liquidation  or
dissolution  of Brandon which is consented to by any Interested Stockholder; (4)
any transaction that has the effect of increasing the proportionate share of any
class or series  of capital stock  that is beneficially  owned by an  Interested
Stockholder;  or (5) the receipt by any Interested Stockholder of the benefit of
any financial benefits provided by Brandon.
 
    The supermajority stockholder vote  is not required,  however, if either  of
the following two conditions is met: (1) the Business Combination is approved by
a   majority  of  those   directors  who  are   not  affiliates,  associates  or
representatives of the Interested  Stockholder and were  not directors prior  to
the  time that the  Interested Stockholder became  an Interested Stockholder; or
(2)  the  aggregate  amount  of  cash  and  the  "Fair  Market  Value"  of   the
consideration other than cash to be received per share by the holders of Brandon
Common  Stock meets  or exceeds  the highest of  the following  four figures, as
adjusted for any stock splits, stock dividends, subdivision, or reclassification
of the  Brandon Common  Stock: (i)  the  highest price  paid by  the  Interested
Stockholder  for a share of Brandon's stock in the two-year period preceding the
announcement of the proposed Business  Combination (the "Announcement Date")  or
the  per share price  paid by the  Interested Stockholder in  the transaction in
which it attained 10% ownership, if higher;  (ii) the higher of the Fair  Market
Value  of Brandon's stock on  the Announcement Date or on  the date on which the
Interested Stockholder attained 10% ownership (the "Determination Date");  (iii)
the  Fair Market Value determined under (ii)  multiplied by the ratio of (x) the
highest price paid by the Interested  Stockholder for a share of Brandon  Common
Stock  within the two-year  period preceding the Announcement  Date over (y) the
price paid by the  Interested Stockholder for its  first share of Brandon  stock
during that same two-year period; or (iv) Brandon's net income per share for the
four fiscal quarters preceding the Announcement Date multiplied by the higher of
(x)  the Interested  Stockholder's price/earnings  multiple on  the Announcement
Date or (y)  Brandon's highest  price/earnings multiple in  the two-year  period
preceding  the Announcement Date. "Fair Market Value" of stock is defined as the
highest closing sale  price of the  stock during the  30 day period  immediately
preceding  the date in question. Similar minimum price requirements apply to the
consideration to be received by holder of  any other class of Brandon stock.  In
addition to the minimum price requirements set forth above, condition (2) is not
satisfied   unless  certain  conditions   are  met  relating   to  the  form  of
consideration,  the  declaration  and  payment  of  dividends,  the  receipt  of
financial  assistance  by  the  Interested  Stockholder  from  Brandon,  and the
circulation of  information relating  to the  proposed Business  Combination  to
Brandon stockholders.
 
    Unlike Brandon, Interim Services defers to the DGCL with respect to business
combinations  between Interim  Services and  interested stockholders  of Interim
Services as  opposed to  stating  particular provisions  in its  Certificate  of
Incorporation. The DGCL defines "Interested Stockholder" as those persons owning
at  least 15% (as opposed to 10% as  provided for in the Brandon Certificate) of
the outstanding voting  stock. The  DGCL also  excludes from  the definition  of
"Interested  Stockholder": (1) any person  who owned shares in  excess of 15% as
of, or acquired such shares pursuant to a
 
                                       59
<PAGE>
tender offer commenced prior to, December  23, 1987, or pursuant to an  exchange
offer  announced  prior  to December  23,  1987,  and commenced  within  90 days
thereafter and continued to own  shares in excess of 15%  or would have but  for
action  by Interim  Services; or  (2) any  person whose  ownership of  shares in
excess of 15% is the result of  action taken solely by Interim Services,  unless
the person acquires additional shares of voting stock thereafter. The definition
of "Business Combination" in the DGCL is substantially similar to the definition
in   the  Brandon  Certificate,  with  the   exception  of  the  following  main
differences:  (1)  the  DGCL  includes   within  the  definition  of   "Business
Combination"  the disposition of assets to  an Interested Stockholder which have
an aggregate value of at least 10% of the market value of the Interim  Services'
total assets, as opposed to 5% of the book value of total assets as provided for
in  the  Brandon  Certificate; and  (2)  the  DGCL does  not  have  a comparable
provision to that of Brandon which includes  the adoption of a plan or  proposal
for  the liquidation or dissolution of the  corporation which is consented to by
any Interested  Stockholder within  the  definition of  "Business  Combination."
Unlike  the  Brandon  Certificate,  the  DGCL  places  limitations  on  Business
Combinations  only  for  the  three-year  period  following  the  date  that   a
stockholder  became an  Interested Stockholder.  During this  three-year period,
Interim Services may not engage in any Business Combination with any  Interested
Stockholder unless one of the following three conditions is satisfied: (1) prior
to  the  date  that  such  Interim  Services  stockholder  became  an Interested
Stockholder, the Interim Board approved  either the Business Combination or  the
transaction  which  resulted in  the  Interim Services  stockholder  becoming an
Interested Stockholder; (2) upon consummation of the transaction which  resulted
in  the  Interim Services  stockholder becoming  an Interested  stockholder, the
Interested Stockholder  owned  at least  85%  of  the voting  stock  of  Interim
Services,  excluding  shares owned  (i) by  persons who  are directors  and also
officers and (ii)  employee stock plans  in which employee  participants do  not
have  the right to  determine confidentially whether shares  held subject to the
plan will  be tendered  in  a tender  or exchange  offer;  or (3)  the  Business
Combination  is approved  by the  Interim Board and  authorized at  an annual or
special meeting, and not by written consent, by the affirmative vote of at least
two-thirds of the outstanding voting stock which is not owned by the  Interested
Stockholder.
 
SHAREHOLDER RIGHTS PLAN
 
    Interim  Services 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  Interim  Services  without  offering  a  fair  price.  SEE
"INFORMATION ABOUT INTERIM SERVICES --  DESCRIPTION OF INTERIM SERVICES  CAPITAL
STOCK."
 
    Brandon has no comparable stockholder rights plan in place.
 
DIVIDEND POLICY
 
    Brandon  has traditionally  distributed quarterly dividends  with respect to
shares of Brandon Common Stock issued and outstanding.
 
    No dividend or other distribution with  respect to Interim Common Stock  has
ever been paid by Interim Services. Interim Services currently intends to retain
any  earnings for use  in its business  and does not  anticipate paying any cash
dividends in the foreseeable future.
 
AUTHORIZED CAPITAL STOCK
 
    The Brandon Certificate provides that  the corporation has the authority  to
issue  11,000,000 shares  of stock, consisting  of 10,000,000  shares of Brandon
Common Stock  and  1,000,000 shares  of  Brandon Preferred  Stock.  The  Brandon
Certificate  expressly provides that the corporation  has the authority to issue
fractional shares. The Interim Certificate provides that the corporation has the
authority to issue 27,500,000 shares  of stock, consisting of 25,000,000  shares
of Interim Common Stock and 2,500,000 shares of Interim Preferred Stock. In each
case, the Preferred Stock is "blank-check" preferred stock, in which the Brandon
Board  and  Interim  Board  can authorize  issuance  of  shares  without further
stockholder consent, and set  the terms, conditions,  preferences and rights  of
such preferred stock.

    On  the Closing  Date, Bryan  Cave LLP will  render the  opinion referred to
under "THE  MERGER  -- CERTAIN  FEDERAL  INCOME  TAX MATTERS."  Bryan  Cave  LLP
represents  Interim Services with respect to the Merger. Bryan Cave LLP does not
represent the individual stockholders of Interim Services in connection with the
Merger and the transactions contemplated  thereby, and such persons are  advised
to  seek  the advice  of their  own  counsel. Additionally,  Bryan Cave  LLP has
rendered an opinion that the shares of Interim Common Stock to be issued in  the
Merger,  when issued pursuant to the terms of the Merger Agreement, will be duly
authorized, validly issued, fully paid and non-assessable.

<PAGE>
                          AGREEMENT AND PLAN OF MERGER
 
    THIS   AGREEMENT  AND  PLAN  OF  MERGER,   dated  February  27,  1996  (this
"Agreement"), is  by and  among INTERIM  SERVICES INC.  ("Interim"), a  Delaware
corporation,  BRANDON SYSTEMS  CORPORATION ("Brandon"),  a Delaware corporation,
and  DELCO  MERGER  CORP.  ("Merger  Sub"),  a  Delaware  corporation  and   the
wholly-owned subsidiary of Interim.
 
    WHEREAS,  Interim and Brandon desire  to combine their respective businesses
and Interim's and Brandon's Board of  Directors each has determined, based  upon
the  terms and conditions hereinafter set forth,  that the combination is in the
best interests of their respective companies and their respective  stockholders;
and
 
    WHEREAS, the combination will be accomplished by merging Merger Sub with and
into  Brandon  with Brandon  surviving  and Brandon  stockholders  receiving the
consideration hereinafter set forth; and
 
    WHEREAS, the Boards  of Directors of  Brandon, Interim and  Merger Sub  have
duly  adopted and approved this Agreement and the Boards of Directors of Brandon
and Interim have directed that it be submitted to their respective  stockholders
for  approval,  the  approval  of  Merger  Sub's  sole  stockholder  having been
obtained;
 
    WHEREAS, to  induce Interim  to  enter into  this  Agreement and  incur  the
obligations  set forth herein,  concurrently with the  execution and delivery of
this Agreement, the principal stockholder of Brandon has granted an  irrevocable
proxy  (the "Stockholder's Proxy")  to designees of  Interim, pursuant to which,
among other  things,  such  designees  have the  right  to  vote  the  principal
stockholder's shares in favor of the Merger;
 
    NOW,  THEREFORE, intending  to be legally  bound, the  parties hereto hereby
agree as follows:
 
                            ARTICLE I -- THE MERGER
 
    1.1.  THE MERGER.  Subject to the terms and conditions of this Agreement, at
the Effective Time (as hereafter defined),  Merger Sub shall be merged with  and
into  Brandon (the "Merger") in accordance with the Delaware General Corporation
Law (the "GCL") and Brandon shall  be the surviving corporation (the  "Surviving
Corporation").  The name of  the Surviving Corporation  shall be BRANDON SYSTEMS
CORPORATION.
 
    1.2.   EFFECT  OF  THE  MERGER.    At  the  Effective  Time,  the  Surviving
Corporation  shall be considered the same  business and corporate entity as each
of Brandon  and Merger  Sub  and thereupon  and  thereafter, all  the  property,
rights,  privileges, powers  and franchises  of each  of Brandon  and Merger Sub
shall vest in the Surviving Corporation  and the Surviving Corporation shall  be
subject  to  and  be deemed  to  have  assumed all  of  the  debts, liabilities,
obligations and  duties  of  each of  Brandon  and  Merger Sub  and  shall  have
succeeded to all of each of their relationships, as fully and to the same extent
as if such property, rights, privileges, powers, franchises, debts, obligations,
duties  and relationships had been originally acquired, incurred or entered into
by the Surviving Corporation. In addition, any reference to either of Brandon or
Merger Sub in any contract or document, whether executed or taking effect before
or after the Effective  Time, shall be considered  a reference to the  Surviving
Corporation  if not  inconsistent with the  other provisions of  the contract or
document; and any pending action or other judicial proceeding to which either of
Brandon or Merger Sub is a party, shall not be deemed to have abated or to  have
discontinued  by reason of the Merger, but  may be prosecuted to final judgment,
order or decree in the same  manner as if the Merger  had not been made; or  the
Surviving  Corporation  may  be  substituted  as  a  party  to  such  action  or
proceeding, and any judgment, order or decree may be rendered for or against  it
that  might have been rendered for or against either of Brandon or Merger Sub if
the Merger had not occurred.
 
    1.3.  CERTIFICATE  OF INCORPORATION.   The Certificate  of Incorporation  of
Merger  Sub as in  effect immediately prior  to the Effective  Time shall be the
Certificate of Incorporation of the Surviving Corporation.
<PAGE>
    1.4.  BY-LAWS.  The By-Laws of Merger Sub as in effect immediately prior  to
the Effective Time shall be the By-Laws of the Surviving Corporation.
 
    1.5.   DIRECTORS AND  OFFICERS.  As  of the Effective  Time, the officers of
Brandon shall  become officers  of the  Surviving Corporation,  subject to  such
changes  or additions as Brandon and Interim  shall mutually agree upon prior to
the Effective Time. As of the Effective Time, the directors of Merger Sub  shall
become  directors of the Surviving Corporation.  One current director of Brandon
shall be appointed to the Board of Directors of Interim, as set forth in Section
6.3(d).
 
    1.6.  EFFECTIVE  TIME AND  CLOSING.  A  closing (the  "Closing") shall  take
place  as soon as practicable after satisfaction or waiver of the conditions set
forth in Article VI (other than the delivery of certificates, opinions and other
instruments and documents to be delivered at the Closing), but in no event later
than five (5)  business days thereafter  (the "Closing Date")  at such place  as
Interim  and Brandon shall  mutually agree. At the  Closing, Interim and Brandon
shall cause the Merger to be consummated  by filing with the Secretary of  State
of  the State of Delaware a certificate  of merger (the "Certificate of Merger")
in such form as is required by, and executed in accordance with, this  Agreement
and  the relevant provisions of the GCL (the  date and time of such filing being
referred to  herein  as  the  "Effective  Time").  As  promptly  as  practicable
following  the Effective  Time, a  copy of  the Certificate  of Merger  shall be
recorded in the office of  the recorder of deeds of  the county of the State  of
Delaware in which the registered office of the Surviving Corporation is located.
 
                   ARTICLE II -- CONVERSION OF BRANDON SHARES
 
    2.1.   CONVERSION OF SHARES.  At the Effective Time, by virtue of the Merger
and without any action on the part of the holders thereof:
 
        (a)  CANCELLED SHARES.  Each share of common stock, par value $0.10  per
    share,  of Brandon  ("Brandon Common  Stock") which  are held  by Brandon as
    treasury shares, and  any shares of  Brandon common Stock  held by  Interim,
    Merger  Sub or any other direct or  indirect subsidiary of Interim, shall be
    cancelled.
 
        (b)  SHARES TO BE EXCHANGED; EXCHANGE RATIO.  Each remaining outstanding
    share of Brandon Common Stock shall  be converted into the right to  receive
    0.88  shares (as the same may be  adjusted as provided herein, the "Exchange
    Ratio") of common  stock, par  value $.01  per share,  of Interim  ("Interim
    Common  Stock").  No  fractional shares  of  Interim Common  Stock  shall be
    issued, and,  in lieu  thereof, a  cash payment  shall be  made pursuant  to
    Section 2.2(e).
 
        (c)  SHARES OF MERGER SUB.  Each issued and outstanding share of capital
    stock  of Merger Sub shall be converted  into one validly issued, fully paid
    and non-assessable share of capital stock of the Surviving Corporation.
 
    2.2.  EXCHANGE OF CERTIFICATES.
 
    (a)  EXCHANGE AGENT.   As of the Effective  Time, Interim shall deposit,  or
shall  cause to be deposited, with a bank or trust company designated by Interim
and reasonably acceptable to Brandon (the "Exchange Agent"), for the benefit  of
the  holders of shares of Brandon Common  Stock, for exchange in accordance with
this Article II, through the  Exchange Agent, certificates evidencing shares  of
Interim  Common Stock and cash in such  amount that the Exchange Agent possesses
such number of shares  of Interim Common  Stock and such amount  of cash as  are
required to provide all of the consideration required to be exchanged by Interim
pursuant  to the provisions of this Article  II (such certificates for shares of
Interim Common Stock, together with any dividends or distributions with  respect
thereto,  and cash  being hereinafter referred  to as the  "Exchange Fund"). The
Exchange Agent shall, pursuant to irrevocable instructions, deliver the  Interim
Common  Stock and cash out of the  Exchange Fund in accordance with Section 2.1.
Except as contemplated by Section 2.2(f) hereof, the Exchange Fund shall not  be
used for any other purpose.
 
                                      A-2
<PAGE>
    (b)    EXCHANGE PROCEDURES.   As  soon as  reasonably practicable  after the
Effective Time, Interim will instruct the Exchange Agent to mail to each  holder
of  record  of a  certificate  or certificates  which  immediately prior  to the
Effective Time  evidenced  outstanding  shares  of  Brandon  Common  Stock  (the
"Certificates"):  (i) a letter of transmittal  (which is reasonably agreed to by
Interim and Brandon and shall specify that delivery shall be effected, and  risk
of  loss and title to the Certificates  shall pass, only upon proper delivery of
the Certificates to and receipt by the Exchange Agent and shall be in such  form
and  have  such other  provisions as  Interim may  reasonably specify)  and (ii)
instructions for use in effecting the surrender of the Certificates in  exchange
for  certificates evidencing shares of Interim Common Stock. Upon surrender of a
Certificate for cancellation to the Exchange Agent together with such letter  of
transmittal,  duly  executed,  and  such other  customary  documents  as  may be
required pursuant to such instructions, the holder of such Certificate shall  be
entitled to receive in exchange therefor (A) certificates evidencing that number
of  whole shares  of Interim  Common Stock  which such  holder has  the right to
receive in respect of the shares  of Brandon Common Stock formerly evidenced  by
such  Certificate in accordance with Section 2.1, (B) cash in lieu of fractional
shares of Interim Common Stock to which such holder may be entitled pursuant  to
Section 2.2(e) and (C) any dividends or other distributions to which such holder
is  entitled pursuant  to Section 2.2(c),  (the shares of  Interim Common Stock,
dividends, distributions and cash  described in clauses (A),  (B) and (C)  being
collectively,  the "Merger  Consideration") and the  Certificates so surrendered
shall forthwith be cancelled. In the event of a transfer of ownership of  shares
of  Brandon Common  Stock which  is not  registered in  the transfer  records of
Brandon, a certificate evidencing the proper number of shares of Interim  Common
Stock  may be issued in  accordance with this Article II  to a transferee if the
Certificate evidencing such shares of Brandon  Common Stock is presented to  the
Exchange  Agent, accompanied  by all documents  required to  evidence and effect
such transfer and by evidence that any applicable stock transfer taxes have been
paid. In the event  any Certificate shall have  been lost, stolen or  destroyed,
upon  the  making of  an  affidavit of  that fact  by  the person  claiming such
Certificate to be lost, stolen or destroyed  and, if required by Interim or  the
Exchange  Agent, the  posting by  such person of  a bond  in such  amount as the
Exchange Agent  may direct  as indemnity  against  any claim  that may  be  made
against  it with respect to  such Certificate, the Exchange  Agent will issue in
exchange for such  lost, stolen destroyed  Certificate the Merger  Consideration
deliverable  in respect thereof pursuant to this Agreement. Until surrendered as
contemplated by this Section 2.2, each  Certificate shall be deemed at any  time
after  the  Effective Time  to  evidence only  the  right to  receive  upon such
surrender the Merger Consideration.
 
    (c)   DISTRIBUTIONS WITH  RESPECT TO  UNEXCHANGED SHARES  OF INTERIM  COMMON
STOCK.  No dividends or other distributions declared or made after the Effective
Time with respect to Interim Common Stock with a record date after the Effective
Time  shall be paid to the holder  of any unsurrendered Certificate with respect
to the shares of Interim  Common Stock evidenced thereby,  and no other part  of
the  Merger Consideration shall be paid to  any such holder, until the holder of
such Certificate  shall surrender  such Certificate.  Subject to  the effect  of
applicable  laws, following  surrender of any  such Certificate,  there shall be
paid to the holder of the certificates evidencing shares of Interim Common Stock
issued in exchange therefor, without interest,  (i) promptly, the amount of  any
cash payable with respect to a fractional share of Interim Common Stock to which
such  holder may have been entitled pursuant to Section 2.2(e) and the amount of
dividends or other  distributions with a  record date after  the Effective  Time
theretofore paid with respect to such shares of Interim Common Stock and (ii) at
the  appropriate payment date,  the amount of  dividends or other distributions,
with a record date after the Effective Time but prior to surrender and a payment
date occurring after surrender, payable with  respect to such shares of  Interim
Common Stock. No interest shall be paid on the Merger Consideration.
 
    (d)   NO  FURTHER RIGHTS  IN BRANDON  COMMON STOCK.   All  shares of Interim
Common Stock  (and other  Merger Consideration)  issued upon  conversion of  the
shares  of Brandon  Common Stock  in accordance with  the terms  hereof shall be
deemed to have been issued in full satisfaction of all rights pertaining to such
shares of Brandon Common Stock.
 
                                      A-3
<PAGE>
    (e)  NO FRACTIONAL SHARES.   No certificates or scrip evidencing  fractional
shares  of Interim Common Stock shall be  issued upon the surrender for exchange
of Certificates and such fractional share  interests will not entitle the  owner
thereof to vote or to any rights of a stockholder of Interim. Cash shall be paid
in lieu of fractional shares of Interim Common Stock, based upon the Median Pre-
Closing  Price per whole share of  Interim Common Stock. The "Median Pre-Closing
Price" shall mean the Median Price of Interim Common Stock calculated based upon
the Closing  Price  of Interim  Common  Stock during  the  first 20  of  the  25
consecutive  trading days  immediately preceding  the date  of the  Closing. The
"Closing Price" shall mean the last reported sale price of Interim Common  Stock
on The Nasdaq Stock Market (formerly known as the Nasdaq National Market System)
and published in The Wall Street Journal. The "Median Price" shall be determined
by  taking the  average of  the Closing Prices  left after  discarding the seven
lowest and seven highest  Closing Prices in the  20-day period. A "trading  day"
shall mean a day for which a Closing Price is so published.
 
    (f)   TERMINATION OF EXCHANGE FUND.   Any portion of the Exchange Fund which
remains undistributed to  the holders  of Brandon  Common Stock  for six  months
after  the  Effective Time  shall  be delivered  to  Interim, upon  demand, and,
subject to Section  2.2(g), any  holders of Brandon  Common Stock  who have  not
theretofore  complied with this Article II shall thereafter look only to Interim
for the Merger Consideration to which they are entitled.
 
    (g)  NO LIABILITY.  Interim shall not  be liable to any holder of shares  of
Brandon  Common Stock for any such shares  of Interim Common Stock (or dividends
or distributions with respect thereto)  delivered to a public official  pursuant
to any applicable abandoned property, escheat or similar law.
 
    (h)   WITHHOLDING RIGHTS.  Interim shall be entitled to deduct and withhold,
or cause  the Exchange  Agent to  deduct and  withhold, from  the  consideration
otherwise  payable pursuant to this Agreement to any holder of shares of Brandon
Common Stock the minimum amounts (if any) that Interim is required to deduct and
withhold with respect to the making  of such payment under the Internal  Revenue
Code  of 1986,  as amended  (the "Code"),  or any  provision of  state, local or
foreign tax law. To  the extent that  amounts are so  withheld by Interim,  such
withheld  amounts shall be treated for all  purposes of this Agreement as having
been paid to  the holder of  the shares of  Brandon Common Stock  in respect  of
which such deduction and withholding was made by Interim.
 
    2.3.     ADJUSTMENTS  TO   EXCHANGE  RATIO  AND   MEDIAN  PRE-CLOSING  PRICE
ADJUSTMENTS.  If between the date of  this Agreement and the Effective Time  the
outstanding  shares  of Interim  Common  Stock shall  have  been changed  into a
different number  of  shares  or a  different  class,  by reason  of  any  stock
dividend,   stock  split,  reclassification,  recapitalization,  combination  or
exchange of shares,  the Exchange Ratio  and the Median  Pre-Closing Price  each
shall  be correspondingly adjusted to reflect  such stock dividend, stock split,
reclassification, recapitalization,  combination  or  exchange  of  shares.  The
parties  shall mutually agree upon  such adjustment in writing  or, if unable to
agree, shall  arbitrate the  dispute, using  a mutually  agreed upon  arbitrator
whose decision shall be final and non-appealable.
 
    2.4.   CLOSING OF  BRANDON'S TRANSFER BOOKS.   Upon the  Effective Time, the
stock transfer books of  Brandon shall be  closed and no  transfer of shares  of
Brandon  Common Stock (other than shares into  which the capital stock of Merger
Sub is to be converted pursuant to  the Merger) shall thereafter be made.  After
the  Effective Time, any Certificates presented to the Exchange Agent or Interim
for any reason shall be converted into the Merger Consideration.
 
    2.5.  BRANDON  STOCK OPTIONS.   Interim agrees to  honor each Brandon  Stock
Option  (as defined in Section 3.2) to  purchase shares of Brandon Common Stock,
in accordance with the terms set forth in Section 3.2 of the Brandon  Disclosure
Schedule  with respect to the  optionee, number of shares  subject to option and
exercise price. At the  Effective Time, each option  shall be converted into  an
option  to  purchase Interim  Common Stock,  wherein (x)  the right  to purchase
shares of Brandon  Common Stock pursuant  to the Brandon  Stock Option shall  be
converted  into the  right to  purchase that  same number  of shares  of Interim
Common Stock multiplied by the Exchange Ratio, (y) the option exercise price per
share of Interim Common  Stock shall be the  previous option exercise price  per
share  of the Brandon Common Stock divided by  the Exchange Ratio and (z) in all
other material
 
                                      A-4
<PAGE>
respects the  option  shall be  subject  to the  same  terms and  conditions  as
governed the Brandon Stock Option on which it was based, including the length of
time  within which  the option may  be exercised  and for any  options which are
"incentive stock  options"  (as  defined  in  Section  422  of  the  Code),  the
adjustments  shall  be and  are intended  to be  effected in  a manner  which is
consistent with Section 424(a) of the Code.
 
    2.6.   MERGER SUB  COMMON STOCK.   The  shares of  Merger Sub  Common  Stock
outstanding  or held in  treasury immediately prior to  the Effective Time shall
not be affected by  the Merger but  shall be converted into  the same number  of
shares of the Surviving Corporation without further action.
 
            ARTICLE III -- REPRESENTATIONS AND WARRANTIES OF BRANDON
 
    References herein to the "Brandon Disclosure Schedule" shall mean all of the
disclosure  schedules required by this Article III,  dated as of the date hereof
and referenced to the specific sections  and subsections of Article III of  this
Agreement,  which have been delivered on the  date hereof by Brandon to Interim.
Brandon hereby represents and warrants to Interim as follows:
 
    3.1.  CORPORATE ORGANIZATION.
 
    (a) Brandon is a  corporation duly organized, validly  existing and in  good
standing  under the  laws of  the State of  Delaware. Brandon  has the corporate
power and authority  to own or  lease all of  its properties and  assets and  to
carry  on its  business as it  is now being  conducted, and is  duly licensed or
qualified to do business and is in  good standing in each jurisdiction in  which
the  nature of the business conducted by it  or the character or location of the
properties  and  assets  owned  or  leased   by  it  makes  such  licensing   or
qualification  necessary, except where the failure  to be so licensed, qualified
or in good standing would  not have a material  adverse effect on the  business,
operations,  assets or financial condition of Brandon and its Subsidiaries taken
as a whole. The Brandon Disclosure Schedule lists each state in which Brandon is
qualified to do business as a  foreign corporation. When used with reference  to
Brandon, the term "Subsidiary" means any corporation, partnership, joint venture
or  other legal entity in which Brandon, directly or indirectly, owns at least a
50% stock or other equity interest or for which Brandon, directly or indirectly,
acts as a general partner.
 
    (b) All Subsidiaries of Brandon and  the percentage of voting securities  of

    is  the  common parent  should  be allocated  or  the manner  in  which such
    allocated liability shall be  paid, (iii) is required  to include in  income
    any  adjustment  pursuant to  Section  481(a) of  the  Code by  reason  of a
    voluntary change in  accounting method initiated  by Brandon or  any of  its
    Subsidiaries  (nor does Brandon have any knowledge that the IRS has proposed
    any such adjustment  or change  of accounting method)  or (iv)  has filed  a
    consent  pursuant to Section  341(f) of the  Code or agreed  to have Section

    promulgated or issued thereunder, and all other applicable governmental laws
    and regulations.
 
        (d) Neither  Brandon nor  any  of its  Subsidiaries,  nor, to  the  best

to the extent that  such assets and  properties have been  disposed of for  fair
value in the ordinary course of business since December 29, 1995), subject to no
encumbrances,  liens, mortgages, security interests or pledges, except (i) those
items that secure liabilities  that are reflected in  said balance sheet or  the

controlled by Interim and its Subsidiaries.
 
    (b) The  business operations  and  all insurable  properties and  assets  of
Interim  and its  Subsidiaries are insured  for their benefit  against all risks
which, in  the reasonable  judgment  of the  management  of Interim,  should  be
insured  against, in  each case  under policies or  bonds issued  by insurers of
recognized responsibility, in  such amounts  with such  deductibles and  against
such  risks  and losses  as  are in  the opinion  of  the management  of Interim
adequate for the business engaged in by Interim and its Subsidiaries. As of  the

employee  or agent) of  Interim or any  of its Subsidiaries  is entitled now, or
will or may be entitled to as a consequence of this Agreement or the Merger,  to
any  payment or benefit from Interim or any of its Subsidiaries, or from Interim
which if paid  or provided would  constitute an "excess  parachute payment",  as
defined in Section 280G of the Code or regulations promulgated thereunder.

or  necessary for the operation of Interim's business as presently conducted and
as currently  proposed to  be conducted.  Except  as set  forth in  the  Interim
Disclosure  Schedule, (i) such  intellectual property rights  are owned free and
clear of royalty  obligations, liens  and encumbrances, (ii)  the execution  and
delivery  of  this Agreement  and the  closing  of the  transaction contemplated
hereby will not  alter or  impair any  such rights, (iii)  the use  of all  such
intellectual  property by Interim does not  infringe or violate the intellectual
property rights of any person  or entity, and (iv)  Interim has not granted  any
person or entity any rights, pursuant to written license agreement or otherwise,
to use such intellectual property. Interim has taken, and shall continue to take
through the Closing Date, all necessary action to maintain and protect each item

    (b) The Interim Disclosure Schedule identifies each patent, trademark, trade
name,  service name or  copyright with respect to  any of Interim's intellectual
property, and the execution  and delivery of this  Agreement and the closing  of
the  transaction  contemplated hereby  will  not materially  adversely  alter or
impair Interim's right with respect thereto.
 
    (c) Interim  has at  all times  used  and will  continue to  use  reasonable
efforts to protect all trade secrets related to its intellectual property.
 
    (d)  Interim has  not interfered  with, infringed  upon, misappropriated, or
otherwise come  into conflict  with any  intellectual property  rights of  third
parties,  nor to the knowledge of Interim  does any of the intellectual property
of Interim interfere with, infringe upon, misappropriate, or otherwise come into
conflict with, any intellectual  property rights of  third parties. Interim  has
not  received  any  complaint,  claim,  demand,  or  notice  alleging  any  such
interference, infringement, misappropriation, or violation (including any  claim
that Interim must license or refrain from using any intellectual property rights
of  any third party), nor  to Interim's knowledge is  there any reasonable basis
therefor. To  the knowledge  of Interim,  no third  party has  interfered  with,
infringed upon, misappropriated, or otherwise come into conflict in any material
respect with any intellectual property rights of Interim.

    Immigration Reform and Control Act of 1986, as amended and supplemented, and

    prospective employees.
 
        (d) Since the approval of each of their respective visa petitions, there
    has been no material change in the terms and conditions of employment by any
    employees of Interim, provided that it is acknowledged that a certain number
    of  employees  from  time  to  time  unilaterally  breach  their  employment
    contracts with Interim.

state and federal laws, rules and regulations and will be included in the Nasdaq
Stock Market.
 
    4.21.  TRANSACTIONS  WITH AFFILIATES.   Except as disclosed  in the  Interim

    5.3.    NO  SOLICITATION.    (a)  Brandon  and  its  affiliates,  employees,
representatives,  financial  advisors  and agents  shall  cease  immediately all
existing discussions  or negotiations,  if  any, with  any parties  (other  than
Interim)  conducted  heretofore  with  respect  to  any  merger,  acquisition or
exchange of all or any material portion of the assets of, or any equity interest
in, Brandon or any of its Subsidiaries or any business combination with  Brandon
or  any of  its Subsidiaries or  any similar transaction.  (Any such transaction
with a  party other  than Interim  or any  affiliate, associate  or designee  of
Interim  is referred to herein as  an "Acquisition Transaction" and any proposal
relating to an Acquisition Transaction is referred to herein as an  "Acquisition
Proposal".)
 
    (b)  Brandon shall not release any third party from, or waive any provisions
of, any confidentiality  or standstill agreement  to which Brandon  is a  party,
unless the Board of Directors of Brandon
 
                                      A-22
<PAGE>
makes  a  determination,  in  good faith  and  after  consultation  with outside
counsel, that to  do so is  required in  the exercise of  its fiduciary  duties.
Brandon  will  use  reasonable efforts  to  have  all copies  of  all non-public
information it or  its agents or  financial advisors have  distributed to  other
potential  purchasers returned  to Brandon  as soon  as possible  after the date
hereof.
 
    (c) Neither Brandon nor any  of its affiliates, employees,  representatives,
financial  advisors or agents shall, directly or indirectly, encourage, solicit,
participate in  or initiate  discussions or  negotiations with,  or provide  any
information  to, any corporation,  partnership, person or  other entity or group
(other than  Interim  or  any  affiliate,  associate  or  designee  of  Interim)
concerning any Acquisition Transaction or Acquisition Proposal.
 
    (d)  Notwithstanding the  foregoing, Brandon  may enter  into discussions or
negotiations with or provide information to a third party in connection with  an
Acquisition  Proposal  provided that  the Board  of  Directors of  Brandon, upon
advice of outside  counsel, determines in  good faith that  the exercise of  its
fiduciary  duties  requires  that  such  discussions  or  negotiations  must  be
commenced or  such  information should  be  provided. Brandon  will  communicate
promptly  to Interim the  terms of any Acquisition  Proposal, whether written or
oral, which it receives  and what response,  if any, the  Board of Directors  of
Brandon  has determined  is necessary  or appropriate,  in accordance  with this
Section 5.3(d). Subject  to any  confidentiality agreement with  any such  third
party  (which Brandon, based upon advice  of outside counsel, determines in good
faith is required to be executed in  order for its Board of Directors to  comply
with  its  fiduciary  duties, but  which  shall  be on  terms  not substantially
different  from  the  confidentiality  agreement  between  Interim  and  Brandon
regarding  the Merger), Brandon shall keep Interim informed of the status of any
such discussions or negotiations.
 
    5.4.   CURRENT  INFORMATION.   During  the  period  from the  date  of  this
Agreement  to the Effective Time, each of  Brandon and Interim will cause one or
more of its  designated representatives  to confer with  representatives of  the
other  party  on  a  monthly  or more  frequent  basis  regarding  its business,
operations, properties, assets and financial  condition and matters relating  to
the  completion of  the transactions  contemplated herein.  On a  monthly basis,
Brandon agrees to provide Interim, and  Interim agrees to provide Brandon,  with
internally  prepared profit and  loss statements no later  than 20 business days
after the close of each fiscal month. As soon as reasonably available, but in no
event more than 45  days after the  end of each fiscal  quarter (other than  the
last  fiscal quarter of each fiscal year)  ending on or after December 31, 1995,
Brandon will  deliver to  Interim  and Interim  will  deliver to  Brandon  their
respective  quarterly reports on Form 10-Q, as filed with the SEC under the 1934
Act. As soon as reasonably  available, but in no event  more than 90 days  after
the  end of each fiscal  year, Brandon will deliver  to Interim and Interim will
deliver to Brandon their  respective Annual Reports on  Form 10-K as filed  with
the SEC under the 1934 Act.
 
    5.5.  ACCESS TO PROPERTIES AND RECORDS; CONFIDENTIALITY.
 
    (a)  Brandon shall permit Interim and its representatives, and Interim shall
permit Brandon and  its representatives, reasonable  access to their  respective
properties,  and shall disclose  and make available  to (and allow  copies to be
made of) Interim and its representatives, or Brandon and its representatives  as
the  case may be,  all books, papers  and records relating  to its assets, stock
ownership, properties, operations, obligations  and liabilities, including,  but
not  limited  to,  all books  of  account  (including the  general  ledger), tax
records, minute books of  directors' and stockholders' meetings,  organizational
documents,   by-laws,  material  contracts  and  agreements,  filings  with  any
regulatory  authority,  accountants'  work   papers,  litigation  files,   plans
affecting  employees, and  any other business  activities or  prospects in which
Interim and its representatives  or Brandon and its  representatives may have  a
reasonable  interest. Neither party shall be required to provide access to or to
disclose information where such access or disclosure would violate or  prejudice
the rights of any customer, would contravene any law, rule, regulation, order or
judgment  or would waive any privilege.  The parties will use reasonable efforts
to  obtain  waivers  of  any  such  restriction  (other  than  waivers  of   the
attorney-client   privilege)  and  in  any  event  make  appropriate  substitute
disclosure arrangements
 
                                      A-23
<PAGE>
under circumstances in which the  restrictions of the preceding sentence  apply.
Notwithstanding  the foregoing,  Interim shall  not be  required to  disclose to
Brandon material non-public information concerning potential acquisitions.
 
    (b) All information furnished by the parties hereto previously in connection
with transactions contemplated  by this  Agreement or pursuant  hereto shall  be
used  solely for  the purpose of  evaluating the Merger  contemplated hereby and
shall be treated as  the sole property of  the party delivering the  information
until  consummation of the Merger contemplated  hereby and, if such Merger shall
not occur, each party and each party's advisors shall return to the other  party
or  destroy all documents or other materials containing, reflecting or referring
to such information, will not retain  any copies of such information, shall  use
reasonable  efforts to  keep confidential  all such  information, and  shall not

commercial  purposes. In the event that  the Merger contemplated hereby does not
occur, all documents, notes and other writings prepared by a party hereto or its
advisors based on  information furnished by  the other party  shall be  promptly
destroyed.  The obligation to keep  such information confidential shall continue
for three years from  the date the  proposed Merger is  abandoned but shall  not
apply  to (i) any information which (A)  the party receiving the information can
establish by convincing  evidence was  already in  its possession  prior to  the
disclosure thereof to it by the other party; (B) was then generally known to the
public;  (C) became known to the public  through no fault of the party receiving
such information; or (D) was disclosed  to the party receiving such  information
by  a  third  party not  bound  by  an obligation  of  confidentiality;  or (ii)
disclosures pursuant to a legal requirement or in accordance with an order of  a
court of competent jurisdiction.
 
    5.6.  REGULATORY MATTERS.
 
    (a)  For the  purposes of holding  the Stockholders Meetings  referred to in
Section 5.7 and  5.8 hereof and  qualifying under applicable  federal and  state
securities laws the Interim Common Stock to be issued to Brandon stockholders in
connection   with  the  Merger,  the  parties  hereto  shall  cooperate  in  the
preparation and filing by Interim of a Registration Statement with the SEC which
shall include an appropriate joint proxy statement and prospectus satisfying all
applicable requirements of applicable state and federal laws, including the 1933
Act, the  1934  Act and  applicable  state securities  laws  and the  rules  and
regulations  thereunder (such joint  proxy statement and  prospectus in the form
mailed by Brandon  to the  Brandon stockholders and  by Interim  to the  Interim
stockholders, together with any and all amendments or supplements thereto, being
herein  referred  to  as  the  "Proxy  Statement/  Prospectus"  and  the various
documents to be filed by Interim under the 1933 Act with the SEC to register the
Interim Common Stock  for sale,  including the  Proxy Statement/Prospectus,  are
referred to herein as the "Registration Statement").
 
    (b)  Interim shall furnish Brandon  with such information concerning Interim
and  its  Subsidiaries   as  is   necessary  in   order  to   cause  the   Proxy
Statement/Prospectus,  insofar as  it relates to  such entities,  to comply with
Section 5.6(a) hereof. Interim agrees promptly to advise Brandon if at any  time
prior  to the Stockholders Meetings  referred to in Section  5.7 and 5.8 hereof,
any information provided  by Interim in  the Proxy Statement/Prospectus  becomes
incorrect  or incomplete in any material respect and to provide Brandon with the
information needed to correct such inaccuracy or omission. Interim shall furnish
Brandon with such supplemental information as may be necessary in order to cause
the Proxy  Statement/Prospectus,  insofar  as  it relates  to  Interim  and  its
Subsidiaries, to comply with Section 5.6(a) after the mailing thereof to Brandon
and Interim stockholders.
 
    (c)  Brandon shall furnish Interim  with such information concerning Brandon
and its  Subsidiaries to  cause the  Proxy Statement/Prospectus,  insofar as  it
relates  to such entities, to comply  with Section 5.6(a) hereof. Brandon agrees
promptly to advise  Interim if at  any time prior  to the Stockholders  Meetings
referred  to in Section 5.7 and 5.8  hereof, any information provided by Brandon
in the  Proxy  Statement/Prospectus  becomes  incorrect  or  incomplete  in  any
material  respect and to provide Interim  with the information needed to correct
such inaccuracy or omission. Brandon shall furnish
 
                                      A-24
<PAGE>
Interim with such supplemental information as may be necessary in order to cause
the Proxy  Statement/Prospectus,  insofar  as  it relates  to  Brandon  and  its
Subsidiaries, to comply with Section 5.6(a) after the mailing thereof to Brandon
and Interim stockholders.
 
    (d)  Interim  shall as  promptly  as practicable  make  such filings  as are
necessary in  connection with  the offering  of the  Interim Common  Stock  with
applicable  state securities  agencies and shall  use all  reasonable efforts to
qualify the offering of such stock under applicable state securities laws at the
earliest practicable  date. Brandon  shall promptly  furnish Interim  with  such
information  regarding the Brandon stockholders as Interim requires to enable it
to determine what filings are required hereunder. Brandon authorizes Interim  to
utilize  in such filings the information concerning Brandon and its Subsidiaries
provided to Interim in  connection with, or contained  in, the Proxy  Statement/
Prospectus.  Interim shall  furnish Brandon's  counsel with  copies of  all such
filings and keep  Brandon advised  of the  status thereof.  Interim and  Brandon
shall  as promptly as practicable file the Registration Statement containing the
Proxy Statement/Prospectus with the SEC, and  each of Interim and Brandon  shall
promptly  notify the other of all communications,  oral or written, with the SEC
concerning the Registration Statement and the Proxy Statement/Prospectus.
 
    (e) Interim shall cause  the Interim Common Stock  issuable pursuant to  the
Merger to be included in the Nasdaq Stock Market at the Effective Time.
 
    (f) The parties hereto will cooperate with each other and use all reasonable
efforts  to prepare, file and diligently  pursue all necessary documentation, to
effect all  necessary filings  and to  obtain all  necessary permits,  consents,
approvals  and  authorizations  of  all third  parties  and  governmental bodies
necessary to consummate the transactions contemplated by this Agreement as  soon
as  possible, including, without limitation, those  required by the HSR Act. The
parties shall  each  have the  right  to review  in  advance all  filings  with,
including  all information relating to the other, as the case may be, and any of
their respective Subsidiaries, which appears in any filing made with, or written
material submitted to, any third party  or governmental body in connection  with
the transactions contemplated by this Agreement.
 
    (g)  Each of  the parties  will promptly furnish  each other  with copies of
written communications received by them or any of their respective  Subsidiaries
from,  or  delivered  by  any  of  the  foregoing  to,  any  stockholder  or any
governmental body  in  respect  of the  transactions  contemplated  hereby  with
respect to the Merger.
 
    (h)  Brandon acknowledges  that Interim is  in or  may be in  the process of
acquiring  other  entities  and  that  in  connection  with  such  acquisitions,
information   concerning  Brandon  may  be  required   to  be  included  in  the
registration statements, if any, for the sale of securities of Interim or in SEC
reports in connection with such acquisitions. Brandon agrees to provide  Interim
with  any information, certificates, documents  or other materials about Brandon
as are  reasonably  necessary  to be  included  in  such other  SEC  reports  or
registration statements, including registration statements which may be filed by
Interim prior to the Effective Time. Brandon shall use its reasonable efforts to
cause  its attorneys and accountants to provide Interim and any underwriters for
Interim  with  any  consents,  comfort  letters,  opinion  letters,  reports  or
information  which  are necessary  to complete  the registration  statements and
applications or any such  acquisition or issuance  of securities. Interim  shall
reimburse  Brandon for reasonable expenses thus  incurred by Brandon should this
transaction be  terminated for  any reason  other than  Brandon breach.  Interim
shall  not file with the SEC any  registration statement or amendment thereto or
supplement thereof containing information regarding Brandon unless Brandon shall
have consented to such filing (and by  such consent Brandon shall not be  deemed
to  pass upon  any information  not supplied  by Brandon  for inclusion  in such
document). Brandon shall not  unreasonably delay or  withhold any such  consent.
Brandon  acknowledges  that Interim  stockholder  approval is  required  for the
Merger whether or  not another  acquisition is  announced prior  to the  Closing
Date.
 
    5.7.    BRANDON  STOCKHOLDERS MEETING.    Brandon  will (a)  take  all steps
necessary duly  to call,  give notice  of, convene  and hold  a meeting  of  the
stockholders of Brandon (the "Brandon Stockholders
 
                                      A-25
<PAGE>
Meeting")  for the purpose  of securing the approval  of Brandon stockholders of
this Agreement, (b) subject to the qualification set forth in Section 5.3 hereof
and the right of its  directors' not to make a  recommendation or to withdraw  a
recommendation  in the exercise of the directors' fiduciary duties in good faith
and based upon the advice of  outside counsel, recommend to the stockholders  of
Brandon  the approval of this Agreement and the transactions contemplated hereby
and  use  reasonable  efforts  to  obtain,  as  promptly  as  practicable,  such
approvals,  and (c) cooperate and  consult with Interim with  respect to each of
the foregoing matters.
 
    5.8.   INTERIM  STOCKHOLDERS MEETING.    Interim  will (a)  take  all  steps
necessary  duly  to call,  give notice  of, convene  and hold  a meeting  of the
stockholders of Interim (the "Interim  Stockholders Meeting" and, together  with
the  Brandon Stockholders Meeting, the  "Stockholders Meetings") for the purpose
of securing the approval of Interim stockholders of this Agreement, (b)  subject
to  the right of  its directors' not to  make a recommendation  or to withdraw a
recommendation in the exercise of the directors' fiduciary duties in good  faith
and  based upon the advice of outside  counsel, recommend to the stockholders of
Interim the approval of this Agreement and the transactions contemplated  hereby
and  use  reasonable  efforts  to  obtain,  as  promptly  as  practicable,  such
approvals, and (c) cooperate  and consult with Brandon  with respect to each  of
the foregoing matters.
 
    5.9.    FURTHER ASSURANCES.    Subject to  the  terms and  conditions herein
provided, each of the parties hereto  agrees to use reasonable efforts to  take,
or  cause to be  taken, all action  and to do,  or cause to  be done, all things
necessary, proper or advisable under applicable laws and regulations to  satisfy
the  conditions to Closing and to consummate and make effective the transactions
contemplated by this Agreement, including, without limitation, using  reasonable
efforts  to lift or rescind  any injunction or restraining  order or other order
adversely affecting the ability  of the parties  to consummate the  transactions
contemplated  by  this Agreement  and using  reasonable  efforts to  prevent the
breach of  any representation,  warranty, covenant  or agreement  of such  party
contained  or referred to in this Agreement  and to promptly remedy the same. In
case at any time  after the Effective  Time any further  action is necessary  or
desirable  to carry out the purposes of  this Agreement, the proper officers and
directors of each party to this Agreement shall take all such necessary  action.
Nothing  in this section shall be construed  to require any party to participate
in any threatened or  actual legal, administrative  or other proceedings  (other
than proceedings, actions or investigations to which it is a party or subject or
threatened to be made a party or subject) in connection with consummation of the
transactions  contemplated by this Agreement unless  such party shall consent in
advance and  in writing  to such  participation and  the other  party agrees  to
reimburse and indemnify such party for and against any and all costs and damages
related thereto.
 
    5.10.   PUBLIC ANNOUNCEMENTS.  Interim and Brandon shall cooperate with each
other in the development and distribution of all news releases and other  public
filings   and  disclosures  with  respect  to   this  Agreement  or  the  Merger
contemplated hereby, and Interim and Brandon agree that unless approved mutually
by them in advance, they will not  issue any press release or written  statement
for  general  circulation  relating primarily  to  the  transaction contemplated
hereby, except as may be otherwise required by law or regulation in the  opinion
of counsel.
 
    5.11.   FAILURE TO FULFILL CONDITIONS.  In the event that Interim or Brandon
determines that  a  material  condition  to its  obligation  to  consummate  the
transactions  contemplated hereby cannot be fulfilled  on or prior to August 31,
1996 (the "Deadline Date") and  that it will not  waive that condition, it  will
promptly   notify  the  other  party.  Except  for  any  acquisition  or  merger
discussions Interim may enter into with other parties, Brandon and Interim  will
promptly  inform  the  other of  any  facts  applicable to  Brandon  or Interim,
respectively, or their respective directors or officers, that would be likely to
prevent or materially delay approval of the Merger by any governmental authority
or which would otherwise prevent or materially delay completion of the Merger.

    5.12.  RETENTION OF EMPLOYEES, OFFICERS; BENEFITS.
 
    (a) Following  consummation  of  the Merger,  Interim  will  use  reasonable
efforts   to  retain   Brandon's  existing  officers   and  full-time  employees
("employees") with levels of aggregate total compensation (salary plus benefits)
substantially equivalent in  the aggregate  to those currently  provided to  the
employees  by  Brandon,  and  with  policies  substantially  equivalent  in  the
aggregate to the employees as those currently followed by Brandon.
 
    (b) The employee benefit plans, arrangements and related policies of Brandon
shall initially be unaffected by the  Merger. Following the Merger, Interim  may
review  such plans, arrangements and policies  with a view towards consolidating
them with Interim's plans, arrangements and policies to the extent feasible  and
consistent  with paragraph (a) above. To the extent current employees of Brandon
become participants in or  subject to a plan,  arrangement or policy of  Interim
(including without limitation those pertaining to medical, vacation, sick leave,
disability,  and pension matters), they will receive credit for prior employment
by Brandon for all purposes in connection with such plan, arrangement or policy,
and no prior existing condition limitation shall be imposed with respect to  any
medical  coverage plan  of Interim (except  to the extent  that such limitations
have already been imposed). If any employees of Brandon immediately prior to the
Effective Time are  involuntarily terminated  by Brandon or  Interim within  one
year  thereafter, they will receive severance  benefits at least as favorable as
those provided  in the  informal  severance plan  of  Brandon contained  in  the
Brandon Disclosure Schedule.
 
    (c)  Following consummation of the Merger, Interim shall honor those written
employment, change in control and termination agreements by and between  Brandon
and/or  its Subsidiaries and  certain employees set forth  in Section 5.12(c) of
the Brandon Disclosure Schedule and shall honor all calculations as to  payments
thereunder  and  interpretations thereof  set forth  in  Section 5.12(c)  of the
Brandon Disclosure Schedule.
 
    5.13.  DISCLOSURE  SUPPLEMENTS.  From  time to time  prior to the  Effective
Time,  each party hereto will promptly supplement or amend (by written notice to
the other) its  respective Disclosure Schedules  delivered pursuant hereto  with
respect  to any matter hereafter arising  which, if existing, occurring or known
at the date  of this  Agreement, would  have been required  to be  set forth  or
described  in such Schedules or which is necessary to correct any information in
such Schedules which has  been rendered materially  inaccurate thereby. For  the
purpose  of determining satisfaction  of the conditions set  forth in Article VI
and subject to Sections  6.2(a) and 6.3(a), no  supplement or amendment to  such
Schedules  shall correct or cure any  representation, warranty or covenant which
was untrue when  made, but shall  enable the disclosure  of subsequent facts  or
events to maintain the truthfulness of any warranty.
 
    5.14.   AFFILIATES.   Simultaneous with  the execution and  delivery of this
Agreement, Brandon shall deliver to Interim a letter agreement, substantially in
the form of  Exhibit 5.14, executed  by Ira  Brown. Promptly, but  in any  event
within  two weeks, after  the execution and delivery  of this Agreement, Brandon
shall deliver  to Interim  (a) a  letter  identifying all  persons who,  to  the
knowledge of Brandon, may be deemed to be affiliates of Brandon, as such term is
defined  in  Rule  405  promulgated  under  the  1933  Act,  including,  without
limitation, all directors and  executive officers of Brandon  and (b) copies  of
letter  agreements, each substantially in the  form of Exhibit 5.14, executed by
each such person so  identified as an  affiliate of Brandon,  for whom a  signed
"affiliate's  letter" has not previously been delivered to Interim. In addition,
Interim shall  cause each  director and  executive officer  of Interim  to,  and
Interim  shall use its best efforts to cause each other person who may be deemed
an affiliate of Interim  (as that term  is used for  purposes of qualifying  for
pooling  of interests) to, execute and deliver to Interim within two weeks after
the execution and  delivery of this  Agreement, a letter  in which such  persons
agree  to be  bound by  the rules  which permit  the Merger  to be  treated as a
pooling of interests for accounting treatment.
 
    5.15.  INDEMNIFICATION; INSURANCE.  Interim  agrees that it will, after  the
Effective  Time, and to the  fullest extent permitted by  applicable law and its
corporate documents, provide to the directors
 
                                      A-27
<PAGE>
and officers  of  Brandon indemnification  equivalent  to that  provided  by  or
available  under  the Certificate  of Incorporation  and  By-laws of  Brandon or
permissible to the fullest extent permitted  under Delaware law with respect  to
acts  or  omissions occurring  prior to  the  Effective Time,  including without
limitation the authorization of this Agreement and the transactions contemplated
hereby, for a period  of six years from  the Effective Time, or  in the case  of
claims  made prior  to the end  of such six  year period, until  such claims are
finally resolved.  To the  extent  permitted by  applicable law,  Interim  shall
advance  expenses as incurred for legal counsel and otherwise in connection with
the foregoing indemnification. Interim will also procure continuing director and
officer liability coverage for directors and officers of Brandon for a period of
six years after the  Effective Time from a  reputable insurance company  issuing
such  policies, with  terms and conditions  (other than the  amount of premiums)
substantially similar to or better than those in effect under Brandon's existing
directors' and officers' insurance  policy; provided, that  if coverage for  six
years  can not be obtained  for $150,000 or less,  Interim shall supply coverage
for three years or for the maximum period obtainable for $150,000, whichever  is
greater.
 
    5.16.   LETTER OF  BRANDON'S ACCOUNTANTS.  Brandon  shall use all reasonable
efforts to cause to be delivered to Interim a "comfort" letter of Coopers, dated
a date  within two  business days  before  the date  on which  the  Registration
Statement  shall become effective and as of the date of Closing and addressed to
Interim, in form and substance reasonably satisfactory to Interim and  customary
in  scope and substance for letters  delivered by independent public accountants
in  connection  with  registration   statements  similar  to  the   Registration
Statement.
 
    5.17.   LETTER OF  INTERIM'S ACCOUNTANTS.  Interim  shall use all reasonable
efforts to cause  to be  delivered to Brandon  a "comfort"  letter of  Deloitte,
dated  a date within two business days before the date on which the Registration
Statement shall become effective and as of the date of Closing and addressed  to
Brandon,  in form and substance reasonably satisfactory to Brandon and customary
in scope and substance for  letters delivered by independent public  accountants
in   connection  with  registration  statements   similar  to  the  Registration
Statement.
 
                        ARTICLE VI -- CLOSING CONDITIONS
 
    6.1.  CONDITIONS  OF EACH  PARTY'S OBLIGATIONS  UNDER THIS  AGREEMENT.   The
respective  obligations of  each party  under this  Agreement to  consummate the
Merger shall  be  subject  to  the satisfaction,  or,  where  permissible  under
applicable  law,  waiver at  or prior  to  the Effective  Time of  the following
conditions:
 
        (a)  APPROVAL OF BRANDON STOCKHOLDERS; SEC REGISTRATION.  This Agreement
    and the transactions  contemplated hereby  shall have been  approved by  the
    requisite  vote  of the  stockholders of  Brandon. The  Interim Registration
    Statement shall have  been declared effective  by the SEC  and shall not  be
    subject  to a stop order  or any threatened stop  order, and the issuance of
    the Interim Common Stock shall have been qualified in every state where such
    qualification is required under the applicable state securities laws.
 
        (b)   REGULATORY  FILINGS.   All  necessary regulatory  or  governmental
    approvals  and consents required to consummate the transactions contemplated
    hereby (other than immaterial government  permits) shall have been  obtained
    without  any term  or condition which  would materially impair  the value of
    Brandon and its Subsidiaries,  taken as a whole,  or which would  materially
    impair  the value  of Interim  and its Subsidiaries,  taken as  a whole. All
    conditions required to be satisfied prior to the Effective Time by the terms
    of such approvals and consents shall have been satisfied; and all  statutory
    waiting  periods in respect  thereof (including the  HSR Act waiting period)
    shall have expired.
 
        (c)   SUITS AND  PROCEEDINGS.   No order,  judgment or  decree shall  be
    outstanding  against a  party hereto  or a third  party that  would have the
    effect of preventing  completion of  the Merger;  no suit,  action or  other
    proceeding  shall be pending or threatened by any governmental body in which
    it is sought  to restrain or  prohibit the  Merger; and no  suit, action  or
    other proceeding shall
 
                                      A-28
<PAGE>
    be  pending before any court or governmental agency in which it is sought to
    restrain or  prohibit the  Merger or  obtain other  substantial monetary  or
    other  relief against  one or  more parties  hereto in  connection with this
    Agreement and which Interim or Brandon determines in good faith, based  upon
    the advice of their respective counsel, makes it inadvisable to proceed with
    the  Merger because  any such suit,  action or proceeding  has a significant
    potential to be resolved in such a way as to deprive the party electing  not
    to proceed of any of the material benefits to it of the Merger.
 
        (d)   TAX  OPINION.   Interim and  Brandon each  shall have  received an
    opinion of Bryan Cave LLP, counsel to Interim, dated as of the Closing Date,
    in form and substance reasonably satisfactory to Interim and to Brandon  and
    its counsel, that for federal and state income tax purposes, the Merger will
    qualify  as a tax-free reorganization under  Section 368(a) of the Code, and
    except with regard to cash received in exchange for fractional shares,  that
    no gain or loss will be recognized by the holders of Brandon Common Stock in
    exchange for their shares of Interim Common Stock.
 
        (e)   POOLING.   Each of the  parties shall have  received an opinion of
    Deloitte and Coopers, respectively, in form and substance reasonably to such
    party, based on such procedures as were deemed relevant, to the effect  that
    the Merger will qualify as a pooling of interests under GAAP.
 
    6.2.   CONDITIONS TO  THE OBLIGATIONS OF  INTERIM AND MERGER  SUB UNDER THIS
AGREEMENT.  The obligations of Interim and Merger Sub under this Agreement shall
be further subject to the satisfaction or  waiver, at or prior to the  Effective

    Brandon shall  have  performed  in all  material  respects  the  agreements,
    covenants  and obligations to be performed by  it prior to the Closing Date.
    With respect to any representation or warranty which as of the Closing  Date
    has required a supplement or amendment to the Brandon Disclosure Schedule to
    render  such representation  or warranty  true and  correct in  all material
    respects as of the  Closing Date, the representation  and warranty shall  be
    deemed  true and correct as of the  Closing Date only if (i) the information
    contained in the supplement or amendment to the Disclosure Schedule  related
    to  events  occurring following  the execution  of  this Agreement  and (ii)
    either (x) the  facts disclosed in  such supplement or  amendment would  not
    either  alone, or together  with any other supplements  or amendments to the
    Brandon Disclosure Schedule, materially adversely effect the  representation
    as  to which the supplement  or amendment relates or  (y) such supplement or
    amendment  remedied  any   material  breach  in   accordance  with   Section
    7.1(d)(ii).

    Pitney, Hardin, Kipp & Szuch, counsel to Brandon, dated the Closing Date, in
    form and substance reasonably satisfactory to Interim, covering the  matters
    set forth on Exhibit 6.2 hereto.
 
        (c)    CERTIFICATES.   Brandon shall  have  furnished Interim  with such
    certificates of its officers or  other documents to evidence fulfillment  of
    the  conditions  set forth  in this  Section 6.2  as Interim  may reasonably
    request.
 
        (d)  [INTENTIONALLY OMITTED].
 
        (e)    APPROVAL  OF  INTERIM  STOCKHOLDERS.    This  Agreement  and  the
    transactions  contemplated hereby shall have  been approved by the requisite
    vote of the stockholders of Interim.

    from DLJ (its "Fairness Opinion"), dated on or shortly prior to the date the

    effect that the Exchange Ratio provided for in this Agreement is fair to the
    holders of Interim  Common Stock  from a financial  point of  view, and  DLJ
    shall not have adversely modified or withdrawn its fairness opinion prior to
    the Closing.

    INTERIM.  Except for those representations which are made as of a particular
    date, the representations and warranties of Interim and Merger Sub contained

    have  performed  in all  material  respects, the  agreements,  covenants and
    obligations to be performed by it prior to the Closing Date. With respect to
    any representation or warranty which as  of the Closing Date has required  a
    supplement  or amendment to  the Interim Disclosure  Schedule to render such
    representation or warranty true and correct  in all material respects as  of
    the  Closing Date, the representation and  warranty shall be deemed true and
    correct as of the Closing Date only if (i) the information contained in  the
    supplement  or  amendment  to  the  Disclosure  Schedule  related  to events
    occurring following the execution of this Agreement and (ii) either (x)  the
    facts  disclosed in such supplement or  amendment would not either alone, or
    together with any other supplements or amendments to the Interim  Disclosure
    Schedule,  materially adversely  effect the  representation as  to which the
    supplement or amendment relates or (y) such supplement or amendment remedied
    any material breach in accordance with Section 7.1(e)(ii).
 
        (b)  OPINION  OF COUNSEL  TO INTERIM.   Brandon shall  have received  an

    Agreement is fair to the holders of Brandon Common Stock, and Goldman  Sachs
    shall not have withdrawn or adversely modified its Fairness Opinion prior to

    discretion.

    Brandon may reasonably request.

        (b) by  Interim or  Brandon (i)  if the  Effective Time  shall not  have
    occurred  on  or prior  to  the Deadline  Date  unless the  failure  of such

<PAGE>

    of the party seeking  to terminate this Agreement  to avoid such result,  or
    (ii)  by Interim upon written  notice to Brandon if  any such application is

    notice  to Interim if any such application is approved with conditions which
    materially impair the  post-Merger value  of Interim  and its  Subsidiaries,
    taken  as a whole, despite  the reasonable efforts of  Brandon to avoid such
    result.
 
        (d) by  Interim if  (i) there  shall have  occurred a  material  adverse
    change  in  the  business,  operations, assets,  or  financial  condition of

stockholders. Nothing contained  herein, however, shall  relieve any party  from
any liability for any breach of this Agreement.
 
    7.4.   AMENDMENT.   This  Agreement may  be amended  by action  taken by the
parties hereto at any  time before or  after adoption of  this Agreement by  the
stockholders of Brandon but, after any such adoption, no amendment shall be made
which  reduces  the  amount or  changes  the  form of  the  consideration  to be
delivered to the stockholders of  Brandon or adversely affects the  stockholders
of  Interim, without the  approval of the  affected stockholders. This Agreement
may not be amended except  by an instrument in writing  signed on behalf of  all
the parties hereto.
 
    7.5.    EXTENSION;  WAIVER.   The  parties may,  at  any time  prior  to the

the  obligations  or other  acts of  the  other parties  hereto; (ii)  waive any
inaccuracies in the representations  and warranties contained  herein or in  any
document  delivered pursuant thereto; or (iii)  waive compliance with any of the
agreements or conditions  contained herein.  Any agreement  on the  part of  any
party  to any such  extension or waiver shall  be valid only if  set forth in an
instrument in writing signed on behalf of such party against which the waiver is
sought to be enforced.
 
                         ARTICLE VIII -- MISCELLANEOUS
 
    8.1.  EXPENSES.
 
    (a) Except  as otherwise  expressly stated  herein, all  costs and  expenses

    (b)  Notwithstanding any provision in this Agreement to the contrary, in the
event that either  of the  parties shall  willfully default  in its  obligations
hereunder, the non-defaulting party may pursue any remedy available at law or in
equity to enforce its rights and shall be paid by the willfully defaulting party
for  all damages,  costs and  expenses, including  without limitation reasonable
legal, reasonable  accounting,  reasonable  investment  banking  and  reasonable
printing   expenses,  incurred  or  suffered  by  the  non-defaulting  party  in

                               FEBRUARY 27, 1996
 
    The undersigned do hereby irrevocably grant to Raymond Marcy, Roy Krause and
John  B. Smith, and each of them, any of whom may act without the joinder of the
other, as their respective  true and lawful  attorneys-in-fact and agents,  with
full  power of substitution and resubstitution, for them and in their respective
names, place and stead, in any and all capacities to vote all of the shares (the
"Subject Shares") of common stock, par value $.10 per share (the "Brandon Common
Stock"), of  Brandon Systems  Corporation, a  Delaware corporation  ("Brandon"),
owned  of  record by  the undersigned,  at  any meeting  of the  stockholders of
Brandon called for the purpose of voting  on the Merger (as defined below)  (and
any adjournment or postponement thereof), solely for the following purposes, and
no  other: (a) in  favor of the Merger  (as defined below)  and the approval and
adoption of the Merger  Agreement (as defined below).  As used herein, the  term
"Merger Agreement" shall mean that certain Agreement and Plan of Merger dated as
of  even date herewith by  and among Brandon, Interim  Services Inc., a Delaware
corporation ("Parent"), and Merger Sub  (as defined therein); the term  "Merger"
shall  have the  meaning ascribed thereto  in the Merger  Agreement; and certain
other capitalized terms  used but  not defined  herein shall  have the  meanings
ascribed thereto in the Merger Agreement.
 
    The undersigned acknowledge and agree that this Irrevocable Proxy is coupled
with  an interest, constitutes, among other things, an inducement for Parent and
Merger Sub to enter into the Merger  Agreement, is irrevocable and shall not  be
terminated  except as set forth herein and  any prior proxies are hereby revoked
and no subsequent proxies will be given  (and, if given, will not be  effective)
prior  to the termination of  this proxy and that  this Irrevocable Proxy is for
the purpose of voting with  respect to the items  set forth in subparagraph  (a)
above and no other, and that voting or granting a proxy to vote on other matters
is not limited by this Irrevocable Proxy.
 
    This  Irrevocable Proxy shall terminate, with  no further action on the part
of any person or entity, (i) on and  as of the earliest of (a) August 27,  1996,
or  (b) the termination  of the Merger  Agreement in accordance  with its terms,
(ii) if the Board of Directors of Brandon shall not have recommended the  Merger
to  Brandon's  stockholders in  the  Proxy Statement/Prospectus,  or  shall have
modified  or  rescinded  its  recommendation  of  the  Merger  to  the   Brandon
stockholders as being advisable and fair to and in the best interests of Brandon
and  its stockholders, or shall  have modified or rescinded  its approval of the
Merger Agreement, or shall have resolved to do any of the foregoing, or (iii) if
Brandon's Board  of Directors  shall have  entered into  a definitive  agreement
contemplating,   announced   or  approved   an  Acquisition   Transaction  after
determining, in  good  faith and  upon  advice  of outside  counsel,  that  such
approval  was necessary in the exercise of its fiduciary duties under applicable
laws.
 
    IN WITNESS WHEREOF, the undersigned have  set their respective hands on  the
27th day of February, 1996.

                          DONALDSON, LUFKIN & JENRETTE
 
                                 APRIL 23, 1996
 
Board of Directors
Interim Services Inc.
2050 Spectrum Blvd.
Ft. Lauderdale, FL 33309
 
Dear Madame and Sirs:
 
    You  have requested our opinion as to the fairness from a financial point of
view to  the  shareholders of  Interim  Services  Inc. (the  "Company")  of  the
consideration  to be  paid by  the Company  in connection  with the  merger (the
"Merger") of Delco Merger Corp., a wholly owned subsidiary of the Company,  with
and  into Brandon Systems  Corporation ("Brandon") pursuant  to an Agreement and
Plan of Merger  (the "Agreement")  dated as of  February 27,  1996, between  the
Company, Delco Merger Corp. and Brandon.
 
    Pursuant  to the  Agreement, each share  of Brandon common  stock, $0.10 par
value per share,  will be converted  into the  right to receive  0.88 shares  of
common stock, $0.01 par value per share of the Company.
 
    In  arriving at our  opinion, we have  reviewed the Agreement  and the Proxy
Statement draft of April 23,  1996 as proposed to  be filed with the  Securities
and  Exchange Commission. We also have  reviewed financial and other information
that was  publicly available  or furnished  to us  by the  Company and  Brandon,
including   information  provided  during   discussions  with  their  respective
managements. Included in  the information provided  during discussions with  the
respective  managements were  certain financial  projections of  Brandon for the
period beginning October  2, 1995  and ending October  1, 1998  prepared by  the
management  of Brandon and certain financial  projections of the Company for the
period beginning January 1,  1996 and ending December  31, 1999 prepared by  the
management  of the Company. In addition,  we have compared certain financial and
securities data of the  Company and Brandon with  various other companies  whose
securities  are traded in  public markets, reviewed prices  and premiums paid in
other business combinations and conducted such other financial studies, analyses
and investigations as we deemed appropriate for purposes of this opinion.
 
    In rendering our  opinion, we  have relied  upon and  assumed the  accuracy,
completeness and fairness of all of the financial and other information that was
available  to us from  public sources, that  was provided to  us by the Company,
Brandon or their respective representatives,  or that was otherwise reviewed  by
us.  With respect to the  financial projections supplied to  us, we have assumed
that they  have  been reasonably  prepared  on  the basis  reflecting  the  best
currently available estimates and judgments of the management of the Company and
Brandon  as to the future operating and financial performance of the Company and
Brandon. We  have not  assumed  any responsibility  for making  any  independent
evaluation  of Brandon's  assets or  liabilities or  for making  any independent
verification of any of the information reviewed by us. We have relied as to  all
legal matters on advice of counsel to the Company. We have also assumed that the
Merger  will qualify as  a pooling of interest  for financial reporting purposes
pursuant to APB 16.
 
    Our opinion is necessarily  based on economic,  market, financial and  other
conditions  as they exist on, and on the information made available to us as of,
the date  of this  letter. It  should be  understood that,  although  subsequent
developments  may affect this opinion, we do  not have any obligation to update,
revise  or  reaffirm   this  opinion.   Our  opinion  does   not  constitute   a
recommendation  to any shareholder as to how such shareholder should vote on the
Merger.

    Based upon the foregoing and such other factors as we deem relevant, we  are
of the opinion that the consideration to be paid by the Company in the Merger is
fair to the shareholders of the Company from a financial point of view.
 
                                          Very truly yours,

PERSONAL AND CONFIDENTIAL
 
April 23, 1996
Board of Directors
Brandon Systems Corporation
9 Polito Avenue
Lyndhurst, NJ 07071
 
Gentlemen and Mesdames:
 
    You  have requested  our opinion as  to the  fairness to the  holders of the
outstanding shares of Common Stock, par value $0.10 per share (the "Shares"), of
Brandon Systems Corporation (the "Company") of the exchange ratio of 0.88 shares
of Common Stock, par value $0.01  per share (the "Interim Services Shares"),  of
Interim  Services Inc. ("Interim  Services") to be received  for each Share (the
"Exchange Ratio")  pursuant to  the Agreement  and Plan  of Merger  dated as  of
February  27,  1996  by  and  among  Interim  Services,  Delco  Merger  Corp., a
wholly-owned subsidiary of Interim Services, and the Company (the "Agreement").
 
    Goldman, Sachs  &  Co., as  part  of  its investment  banking  business,  is
continually  engaged  in the  valuation of  businesses  and their  securities in
connection with mergers and acquisitions, negotiated underwritings,  competitive
biddings,  secondary distributions  of listed  and unlisted  securities, private
placements and  valuations for  estate,  corporate and  other purposes.  We  are
familiar  with the Company  having acted as its  financial advisor in connection
with, and having  participated in certain  of the negotiations  leading to,  the
Agreement.  We have also provided certain investment banking services to Interim
Services from  time to  time, including  acting as  managing underwriter  of  an
initial public offering of common stock of Interim Services in January 1994, and
we may provide investment banking services to Interim Services from time to time
in the future.
 
    In  connection with this opinion, we  have reviewed, among other things, the
Agreement; the Proxy Statement/Prospectus  dated April 23,  1996 of the  Company
and  Interim Services; Annual Reports to Stockholders and Annual Reports on Form
10-K of the  Company for the  five fiscal  years ended October  1, 1995;  Annual
Reports  to Stockholders and Annual Reports on Form 10-K of Interim Services for
the fiscal year ended  March 25, 1994  and the fiscal  years ended December  30,
1994 and December 29, 1995; the Prospectus of Interim Services dated January 27,
1994,  which includes audited  financial statements of  Interim Services for the
three fiscal years ended March  26, 1993, and for  the 26 weeks ended  September
24,  1993; certain interim reports to stockholders and Quarterly Reports on Form
10-Q for each of the Company and Interim Services; certain other  communciations
from  the Company  and Interim  Services to  their respective  stockholders; and
certain internal financial analyses  and forecasts for each  of the Company  and
Interim  Services prepared  by their respective  managements. We  have also held
discussions with members of  the senior managements of  the Company and  Interim
Services   regarding  the  past  and   current  business  operations,  financial
conditions and future prospects of  their respective companies. In addition,  we
have  reviewed the reported  price and trading  activity for the  Shares and the
Interim Services Shares, compared certain financial and stock market information
for the Company and Interim Services with similar information for certain  other
companies  the securities of  which are publicly  traded, reviewed the financial
terms of certain recent business combinations in the temporary staffing industry
specifically and other industries generally and performed such other studies and
analyses as we considered appropriate.
<PAGE>
    We have  relied  without  independent verification  upon  the  accuracy  and
completeness  of all of the  financial and other information  reviewed by us for
purposes of  this  opinion.  We  have not  made  an  independent  evaluation  or
appraisal  of the assets and  liabilities of the Company  or Interim Services or
any of  their  subsidiaries  and  we  have not  been  furnished  with  any  such
evaluation  or appraisal. We have also assumed with your consent that the Merger
will be  accounted  for as  a  pooling  of interests  under  generally  accepted
accounting principles.
 
    Based upon and subject to the foregoing and based upon such other matters as
we  consider relevant, it is our opinion that as of the date hereof the Exchange
Ratio pursuant to the Agreement is fair to the holders of Shares.
 
Very truly yours,
GOLDMAN, SACHS & CO.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    INTERIM SERVICES' AMENDED AND RESTATED CERTIFICATE OF INCORPORATION
 
    SIXTH:  (A)  Interim 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 Interim) by reason of the fact that he, his
testator or intestate, is or was a  director or officer of Interim or by  reason
of  the fact that such director or officer, at the request of Interim, 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 stockholder  of Interim  shall be  personally liable  to
Interim  or its  stockholders 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  Interim or its  stockholders, (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 Interim 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.
 
    INTERIM SERVICES' BYLAWS
 
24.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    (a)  POWER TO INDEMNIFY IN ACTIONS, SUITS OR PROCEEDINGS OTHER THAN THOSE BY
OR IN THE  RIGHT OF INTERIM.   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, 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
 
                                      II-1
<PAGE>
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 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.
 
        (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
 
                                      II-2
<PAGE>
    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 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 or she
is  not entitled  to be  indemnified by  the corporation  as authorized  in this
Section 24; provided, however, that
 
                                      II-3
<PAGE>
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.
 
    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.

ITEM 22.  UNDERTAKINGS.
 
    (a) The undersigned registrant hereby undertakes:
 
        (1)  To file, during any period in which offers or sales are being made,
    a post-effective amendment to this registration statement;
 
           (i) To include  any prospectus  required by section  10(a)(3) of  the
       Securities Act of 1933;
 
           (ii)  To reflect in the prospectus  any facts or events arising after
       the effective  date of  the registration  statement (or  the most  recent
       post-effective   amendment  thereof)   which,  individually   or  in  the
       aggregate, represent a fundamental change in the information set forth in
       the registration statement. Notwithstanding  the foregoing, any  increase
       or decrease in volume of securities offered (if the total dollar value of
       securities  offered would not  exceed that which  was registered) and any
       deviation from the  low or  high and  of the  estimated maximum  offering
       range  may  be  reflected  in  the  form  of  prospectus  filed  with the
       Commission pursuant to Rule 424(b) if,  in the aggregate, the changes  in
       volume  and  price represent  no more  than  a 20  percent change  in the
       maximum aggregate  offering  price  set  forth  in  the  "Calculation  of
       Registration Fee" table in the effective registration statement.
 
          (iii)  To include any material information with respect to the plan of
       distribution not previously  disclosed in the  registration statement  or
       any material change to such information in the registration statement;
 
    PROVIDED,  HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
    the registration statement is on  Form S-3, Form S-8,  or Form F-3, and  the
    information required to be included in the post-effective amendment by those
    paragraphs  is contained in periodic reports  filed with or furnished to the
    Commission by the  registrant pursuant  to Section  13 or  Section 15(d)  of
    Securities  Exchange Act of  1934 that are incorporated  by reference in the
    registration statement.
 
        (2) That,  for  the  purpose  of determining  any  liability  under  the
    Securities  Act of 1933, each such  post-effective amendment shall be deemed
    to be  a  new registration  statement  relating to  the  securities  offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.
 
        (3)  To remove from registration by  means of a post-effective amendment
    any  of  the  securities  being  registered  which  remain  unsold  at   the
    termination of the offering.
 
    (b)  The  undersigned registrant  hereby  undertakes that,  for  purposes of
determining any liability under the Securities  Act of 1933, each filing of  the
registrant's  annual report  pursuant to Section  13(a) or Section  15(d) of the
Securities Exchange  Act of  1934  (and, where  applicable,  each filing  of  an
employee  benefit  plan's  annual  report  pursuant  to  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 offered therein, and the offering of such  securities
at that time shall be deemed to be the initial BONA FIDE offering thereof.
 
    (c)  The undersigned registrant hereby undertakes  as follows: that prior to
any public  reoffering  of securities  registered  hereunder through  use  of  a
prospectus  which is  a part  of this registration  statement, by  any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c),  the
issuer  undertakes that such reoffering  prospectus will contain the information
called for by the  applicable registration form with  respect to reofferings  by
persons  who may be  deemed underwriters, in addition  to the information called
for by the other items of the applicable form.
 
    (d) The undersigned registrant undertakes that every prospectus: (i) that is
filed pursuant to paragraph (c) immediately preceding, or (ii) that purports  to
meet  the requirements of Section 10(a)(3) of  the Act and is used in connection
with an offering of securities subject to Rule  415, will be filed as a part  of
an  amendment to  the registration  statement and  will not  be used  until such
amendment is  effective, and  that, for  purposes of  determining any  liability
under the Securities Act of
 
                                      II-7
<PAGE>
1933,   each  such  post-effective  amendment  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.
 
    (e) 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 questions 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.
 
    (f) The undersigned registrant hereby undertakes to respond to requests  for
information  that is incorporated  by reference into  the prospectus pursuant to
Item 4, 10(b), 11,  or 13 of this  form, within one business  day of receipt  of
such  request, and  to send  the incorporated documents  by first  class mail or
other equally prompt  means. This  includes information  contained in  documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
    (g)  The undersigned  registrant hereby undertakes  to supply by  means of a
post-effective amendment  all  information  concerning a  transaction,  and  the
company  being  acquired  involved therein,  that  was  not the  subject  of and
included in the registration statement when it became effective.

Ladies and Gentlemen:
 
    We  refer to  the Registration  Statement (the  "Registration Statement") of
Interim Services Inc., a Delaware corporation (the "Company"), filed on Form S-4
with the Securities and  Exchange Commission (the "SEC")  to register under  the
Securities  Act of  1933, as  amended (the "Act"),  the offer  to sell 4,897,546
shares of the  Company's common  stock, par value  $.01 per  share (the  "Common
Stock"). The Common Stock is being offered to holders of common stock of Brandon
Systems  Corporation,  a  Delaware  corporation  ("Brandon"),  pursuant  to  the
proposed merger (the "Merger") of Delco Merger Corp., a Delaware corporation and
a wholly-owned subsidiary of the Company, with and into Brandon.
 
    In this  connection,  we have  examined  originals or  copies  certified  or
otherwise   identified  to  our  satisfaction  of  such  corporate  records  and
agreements of the Company, and such instruments and documents, including officer
certificates and certificates of public  officials, as we have deemed  necessary
as a basis for the opinions hereinafter expressed.
 
    Based   on  the  foregoing  and  subject  to  the  assumptions,  exceptions,
qualifications and limitations set forth below, we are of the opinion that:
 
        1.  The Company is a corporation duly organized, validly existing and in
    good standing under the laws of the State of Delaware.
 
        2.  The shares of Common  Stock registered pursuant to the  Registration
    Statement  will have been, at the time  of their issuance in accordance with
    the Merger, duly authorized, validly issued, fully paid and non-assessable.
 
    The opinions expressed herein  are limited by, subject  to and based on  the
following assumptions, exceptions, qualifications and limitations:
 
        a.   The opinions stated herein are as of the date hereof, and we assume
    no obligation to  update or  supplement this  legal opinion  to reflect  any
    facts  or  circumstances that  may hereafter  come to  our attention  or any
    changes in laws that may hereafter occur.
 
        b.  This legal opinion  is limited to the  matters stated herein and  no
    opinion is implied or may be inferred beyond the matters expressly stated.
<PAGE>
    We  consent  to  the filing  of  this legal  opinion  as an  exhibit  to the

Dear Board of Directors:
 
    This  opinion is  delivered in our  capacity as counsel  to Interim Services
Inc., a Delaware corporation ("Interim Services"), pursuant to Section 6.1(d) of
the  Agreement  and  Plan  of  Merger  dated  February  27,  1996  (the  "Merger
Agreement")  by  and  among  Interim Services,  Brandon  Systems  Corporation, a
Delaware corporation ("Brandon"), and Delco Merger Corp., a Delaware corporation
and a  wholly-owned  subsidiary  of  Interim Services  ("Merger  Sub"),  and  in
connection  with  the filing  of  the Registration  Statement  on Form  S-4 (the
"Registration Statement")  filed as  Joint Proxy  Statement/Prospectus with  the
Securities  and Exchange Commission on April   , 1996 (No.        ). Capitalized
terms not otherwise defined  herein shall have the  meaning ascribed to them  in
the Merger Agreement.
 
    In  rendering this opinion, we have reviewed copies of the Merger Agreement,
the Registration Statement, and such other documents as we have deemed necessary
or relevant for  purposes of this  opinion. In addition  to these documents,  we
have relied on the written representations of Interim Services and Brandon as to
certain factual matters.
 
    In  rendering  the  opinion  set  forth  herein,  we  have  assumed  (i) the
genuineness  of  all  signatures  on  documents  we  have  examined,  (ii)   the
authenticity of all documents submitted to us as originals, (iii) the conformity
to  the original documents of all documents  submitted to us as copies, (iv) the
authority and capacity of  the individual or individuals  who executed any  such
documents  on behalf  of any  person, (v) the  accuracy and  completeness of all
documents made available  to us and  (vi) the accuracy  as to the  facts of  all
representations,  warranties  and  written  statements.  We  have  also assumed,
without investigation, that all documents, warranties and covenants relating  to
the Merger on which we have relied in rendering the opinions set forth below and
that were given or dated earlier than the date of this letter continue to remain
accurate, insofar as relevant to the opinion set forth herein, from such earlier
date through and including the date of this letter.
 
                                    OPINION
 
    Based  upon  the  foregoing,  and  assuming  the  Merger  is  consummated in
accordance with  the  Merger  Agreement,  and  subject  to  the  conditions  and
limitations  contained herein, we are of the  opinion that: (1) the Merger, when
consummated in  accordance  with  the  terms of  the  Merger  Agreement  and  as
described in the Registration Statement, will constitute a reorganization within
the
<PAGE>
meaning  of Sections 368(a)(1)(A) and 368(a)(2)(E)  of the Internal Revenue Code
of 1986, as amended (the "Code")(1); and (2) the federal income tax consequences
to the parties, as set forth in the Registration Statement and as set forth more
fully below, are true and complete in all material respects.
 
    A reorganization  qualifying under  Sections 368(a)(1)(A)  and  368(a)(2)(E)
will result in the following federal income tax consequences:
 
    1.   No gain or loss will be recognized by Brandon or Merger Sub as a result
of the Merger.
 
    2.  No gain or loss will be recognized by Interim Services upon the exchange
of Interim Common Stock for Brandon Common Stock pursuant to the Merger.
 
    3.   No gain  or  loss will  be recognized  by  a Brandon  stockholder  upon
exchange  of  Brandon Common  Stock  for Interim  Common  Stock pursuant  to the
Merger.
 
    4.  The basis of the Interim Common Stock received by a Brandon  stockholder
pursuant  to the Merger (including any fractional share) will be the same as the
basis of  the  Brandon  Common  Stock surrendered  in  exchange  therefor;  and,
provided  that  such Brandon  Common Stock  is held  as a  capital asset  at the
Effective Time, the holding period of  such Interim Common Stock (including  any
fractional share) will include the period during which such Brandon Common Stock
was held.
 
    5.   A Brandon stockholder  who receives cash in  lieu of a fractional share
will recognize gain or loss as if he had received such fractional share and sold
it for cash at the Effective Time.
 
                                   * * * * *
 
    The foregoing  opinions reflect  our best  professional judgment  as to  the
correct federal income tax treatment, under current law, of those aspects of the
proposed  transactions to which the opinions relate. We note that our opinion is
based upon  our review  of the  documents described  above, the  statements  and
representations  referred to above, the provisions of the Code, the regulations,
published rulings and announcements thereunder, and the judicial interpretations
thereof, currently in effect. Any change in  applicable law or any of the  facts
and  circumstances described in the Registration Statement, or inaccuracy of any
statements or representations on which we have relied, may effect the continuing
validity of our opinion.
 
    We hereby  consent to  the  filing of  this opinion  as  an exhibit  to  the
Registration  Statement and  to the  use of  our name  under the  caption "Legal
Matters" in the  proxy statement/prospectus  filed as  a part  thereof. We  also
consent  to your filing copies of this opinion as an exhibit to the Registration
Statement with agencies of such  states as you deem  necessary in the course  of
complying  with the  laws of  such states regarding  the Merger.  In giving this
consent, we do not  hereby admit that  we are in the  category of persons  whose
consent  is required under section 7 of the  Act or the rules and regulations of
the Securities and Exchange Commission.
