                                  THE COMPANY
 
    Whittman-Hart,  Inc. ("Whittman-Hart"  or the  "Company") provides strategic
information  technology  ("IT")  services  designed  to  improve  its   clients'
productivity  and competitive position. The Company  offers its clients a single
source for a comprehensive  range of services  required to successfully  design,
develop  and implement integrated computer systems projects in diverse computing
environments. Among the services offered by the Company are systems integration,
strategic IT planning,  software development,  packaged software  implementation
(such  as  SAP's  R/3  client/server  application  software),  business  process
reengineering, organizational  change management,  networking and  connectivity,
conventional   and   multimedia   documentation   and   training,   design   and
implementation of  workgroup solutions  (such  as Lotus  Notes) and  design  and
implementation  of electronic commerce solutions  (such as intranet/Internet and
EDI).
 
    Whittman-Hart's marketing efforts focus  on middle market companies  ranging
from  $50 million to  $500 million in  annual revenues and  divisions of Fortune
1000 companies. Whittman-Hart  serves clients  in a broad  range of  industries,
including communications, consumer products, distribution, diversified services,
financial  services,  insurance,  manufacturing,  pharmaceuticals,  professional
services, retail and technology. The  Company employs consultants with  business
experience in these areas to enhance its ability to understand industry-specific
business  issues and develop unbiased IT  solutions to address these issues. The
number of clients billed  by the Company has  grown from 338 in  1993 to 492  in
1995.   The  Company  believes  that  it  has  established  significant  ongoing
relationships with many of its clients.
 
    The demand for IT consulting services has increased rapidly in recent  years
and  is continuing to  grow because: (i) businesses  and other organizations are
becoming more reliant on  IT for their competitive  success; (ii) companies  are
migrating  from  centralized,  mainframe-based computer  systems  to distributed
client/server environments; (iii) widespread organizational downsizing  requires
improved  business  process efficiencies;  (iv)  IT solutions  have  become more
complex; and (v) organizations do not generally possess the quantity and variety
of IT skills needed to execute  complex IT projects. Whittman-Hart has  competed
successfully  in this environment, experiencing a compound annual revenue growth
rate of  46%  over the  past  three fiscal  years.  For fiscal  year  1995,  the
Company's  revenues were $49.8 million, an increase of 69% from $29.5 million in
fiscal year 1994. Revenues  for the six  months ended June  30, 1996 were  $38.9
million, an increase of 82% from $21.4 million in the corresponding 1995 period.
From  June 30, 1995  to June 30,  1996, the number  of consultants increased 69%
from 425 to 718.
 
    Whittman-Hart sells  and delivers  its  services through  a network  of  six
branch  offices located in Chicago,  Indianapolis, Denver, Cincinnati, Milwaukee
and Dallas. The Company has developed  a national branch expansion strategy  and
has  begun replicating its business model  in additional major domestic markets.
Expansion plans for 1996 include a Dallas branch, opened in January 1996, and an
additional branch, scheduled  to open  in late 1996.  In support  of its  growth
strategy,  Whittman-Hart has  made significant  investments in  its business and
systems infrastructure,  recruiting  organization,  training  methodologies  and
marketing  programs,  all of  which the  Company believes  will be  necessary to
support a  significantly  larger  organization. The  Company's  growth  strategy
includes  the  following  elements:  (i)  expanding  service  capabilities; (ii)
increasing  client  penetration  by  cross-selling  additional  services;  (iii)
acquiring  other  firms  to  facilitate entry  into  new  geographic  markets or
increase technical expertise; and (iv) seeking strategic relationships to  share
technical and industry knowledge and pursue joint marketing opportunities.

<PAGE>
                                  RISK FACTORS
 
    IN ADDITION TO THE OTHER INFORMATION SET FORTH IN THIS PROSPECTUS, INVESTORS
SHOULD CONSIDER CAREFULLY THE FOLLOWING FACTORS IN CONNECTION WITH AN INVESTMENT
IN THE SHARES OF COMMON STOCK OFFERED HEREBY (THE "SHARES").
 
ATTRACTION AND RETENTION OF EMPLOYEES
 
    The Company's business involves the delivery of professional services and is
labor-intensive. The Company's success depends in large part upon its ability to
attract,  develop,  motivate  and  retain  highly  skilled  technical employees.
Qualified technical employees  are in great  demand and are  likely to remain  a
limited  resource for the foreseeable future. There can be no assurance that the
Company will be able to attract and retain sufficient numbers of highly  skilled
technical  employees  in the  future. The  Company has  historically experienced
turnover rates which it believes are consistent with industry norms. An increase
in this rate  could have a  material adverse effect  on the Company's  business,
operating  results and financial condition, including  its ability to secure and
complete engagements. See "Business -- Human Resources."
 
MANAGEMENT OF GROWTH
 
    The Company is currently  experiencing rapid growth  that has strained,  and
could  continue to  strain, the Company's  managerial and  other resources. From
June 30, 1995 through  June 30, 1996, the  number of consultants increased  from
425  to 718 and further significant increases are anticipated during the current
year. The Company opened a Dallas branch  in January 1996, and plans to open  an
additional  branch in  late 1996.  The Company  also intends  to open additional
offices in  the  future. The  Company's  ability to  manage  the growth  of  its
operations will require it to continue to improve its operational, financial and
other  internal  systems  and  to  attract,  develop,  motivate  and  retain its
employees. If  the  Company's management  is  unable  to manage  growth  or  new
employees  are unable to  achieve anticipated performance  levels, the Company's
business, operating  results and  financial condition  could be  materially  and
adversely affected.
 
PROJECT RISKS
 
    Many  of the Company's engagements involve projects that are critical to the
operations of its clients' businesses and provide benefits that may be difficult
to quantify. The Company's failure or inability to meet a client's  expectations
in  the performance of its services could result in a material adverse change to
the client's operations  and therefore  could give  rise to  claims against  the
Company  or damage the  Company's reputation, adversely  affecting its business,
operating results and financial condition.
 
VARIABILITY OF QUARTERLY OPERATING RESULTS
 
    Variations in the Company's revenues  and operating results occur from  time
to  time as a result of a number  of factors, such as the significance of client
engagements commenced and  completed during  a quarter, the  number of  business
days  in a quarter, timing of branch  and service line expansion activities, the
timing of corporate expenditures and employee hiring and utilization rates.  The
timing  of revenues is  difficult to forecast because  the Company's sales cycle
can be relatively long and may depend on  factors such as the size and scope  of
assignments  and general economic  conditions. Because a  high percentage of the
Company's expenses are  relatively fixed, a  variation in the  number of  client
assignments  or  the  timing  of  the initiation  or  the  completion  of client
assignments, particularly  at  or  near  the  end  of  any  quarter,  can  cause
significant  variations in operating  results from quarter  to quarter and could
result in losses to the Company. In addition the Company's engagements generally
are terminable by the client without penalty. Although the number of consultants
can be adjusted to correspond to the number of active projects, the Company must
maintain a sufficient number  of senior consultants  to oversee existing  client
projects  and  assist with  the  Company's sales  force  in securing  new client
assignments. See "Management's  Discussion and Analysis  of Financial  Condition
and Results of Operations."
 
COMPETITION
 
    The  market  for IT  services  includes a  large  number of  competitors, is
subject to rapid change and  is highly competitive. Primary competitors  include
participants  from a variety of market  segments, including "Big Six" accounting
firms, systems consulting and implementation firms, application software  firms,
service groups of computer equipment companies, facilities management companies,
general  management consulting  firms and  programming companies.  Many of these
competitors have significantly greater financial,
 
                                       5
<PAGE>
technical and marketing resources and greater name recognition than the Company.
In  addition,  the  Company  competes  with  its  clients'  internal  resources,
particularly  where these resources  represent a fixed cost  to the client. Such
competition may impose additional pricing pressures on the Company. There can be
no assurance  that  the Company  will  compete successfully  with  its  existing
competitors or with any new competitors. See "Business -- Competition."
 
RELIANCE ON KEY EXECUTIVES
 
    The  success  of  the  Company  is highly  dependent  upon  the  efforts and
abilities of  its  executive  officers, particularly  Mr.  Robert  Bernard,  the
Company's  founder and Chief  Executive Officer. Although  these executives have
entered into employment agreements containing noncompetition, nondisclosure  and
nonsolicitation   covenants,  these  contracts  do   not  guarantee  that  these
individuals will continue  their employment with  the Company. The  loss of  the
services  of any of  these key executives  for any reason  could have a material
adverse effect  upon the  Company's business,  operating results  and  financial
condition. See "Management -- Employment Agreements."
 
CONCENTRATION OF REVENUES
 
    The  Company derives a significant portion of its revenues from a relatively
limited number of clients. For example during fiscal year 1995 and the first six
months of  1996,  revenues  from  the Company's  ten  most  significant  clients
accounted  for  approximately  33%  of  its  revenues,  and  its  largest client
accounted for approximately 10% and 8% of the Company's revenues,  respectively.
There can be no assurance that these clients will continue to engage the Company
for  additional projects or do so at the same revenue levels. Clients engage the
Company on  an  assignment-by-assignment  basis,  and  a  client  can  generally
terminate an assignment at any time without penalty. The loss of any significant
client could have a material adverse effect on the Company's business, operating
results  and financial condition.  See "Management's Discussion  and Analysis of
Financial Condition  and Results  of Operations"  and "Business  -- Clients  and
Representative Solutions."
 
RAPID TECHNOLOGICAL CHANGE; DEPENDENCE ON NEW SOLUTIONS
 
    The  Company's success  will depend  in part  on its  ability to  develop IT
solutions that  keep  pace with  continuing  changes in  IT,  evolving  industry
standards  and changing client  preferences. There can be  no assurance that the
Company will  be successful  in adequately  addressing these  developments on  a
timely  basis or that, if these developments  are addressed, the Company will be
successful in  the marketplace.  In addition,  there can  be no  assurance  that
products  or  technologies developed  by others  will  not render  the Company's
services uncompetitive  or  obsolete. The  Company's  failure to  address  these
developments  could have  a material adverse  effect on  the Company's business,
operating results and financial condition.
 
RISKS RELATED TO POSSIBLE ACQUISITIONS
 
    The Company may expand its operations through the acquisition of  additional
businesses. There can be no assurance that the Company will be able to identify,
acquire or profitably manage additional businesses or successfully integrate any
acquired  businesses into  the Company  without substantial  expenses, delays or
other operational or  financial problems.  Further, acquisitions  may involve  a
number  of  special  risks  or  effects,  including  diversion  of  management's
attention, failure to  retain key  acquired personnel,  unanticipated events  or
circumstances,  legal liabilities and amortization of acquired intangible assets
and other one-time or ongoing acquisition related expenses, some or all of which
could have  a  material adverse  effect  on the  Company's  business,  operating
results  and financial condition. Client satisfaction or performance problems at
a single acquired firm could have a material adverse impact on the reputation of
the Company as a  whole. In addition,  there can be  no assurance that  acquired
businesses,  if any, will achieve anticipated revenues and earnings. The failure
of the Company  to manage  its acquisition  strategy successfully  could have  a
material  adverse  effect  on  the  Company's  business,  operating  results and
financial condition. See "Business -- Growth Strategy."
 
CONTROL BY PRINCIPAL STOCKHOLDER
 
   
    After completion  of  this  offering,  Mr.  Bernard  will  beneficially  own
approximately  38.4% of the  Company's outstanding shares of  Common Stock. As a
result, Mr. Bernard will, as a practical matter,
    
 
                                       6
<PAGE>
continue to be able  to control the outcome  of matters requiring a  stockholder
vote,  including the election of the members  of the Board of Directors, thereby
controlling the  affairs  and management  of  the Company.  Such  control  could
adversely  affect the  market price of  the Common  Stock or delay  or prevent a
change in control of the Company. See "Principal and Selling Stockholders."
 
INTELLECTUAL PROPERTY RIGHTS
 
    The Company's success is dependent upon certain methodologies it utilizes in
designing, installing and  integrating computer software  and systems and  other
proprietary  intellectual property  rights. The Company's  business includes the
development of custom software in  connection with specific client  engagements.
Ownership of such software is generally assigned to the client. The Company also
develops  certain  foundation  and application  software  products,  or software
"tools," which remain the property of the Company.
 
    The Company relies upon a combination of nondisclosure and other contractual
arrangements and  trade secret,  copyright  and trademark  laws to  protect  its
proprietary  rights and  the proprietary rights  of third parties  from whom the
Company licenses intellectual property. The Company enters into  confidentiality
agreements   with  its   employees  and   limits  distribution   of  proprietary
information. There can be no  assurance that the steps  taken by the Company  in
this   regard  will  be  adequate   to  deter  misappropriation  of  proprietary
information or that the Company will be able to detect unauthorized use and take
appropriate steps to enforce its intellectual property rights.
 
    Although the  Company believes  that its  services do  not infringe  on  the
intellectual  property rights of others and that  it has all rights necessary to
utilize the  intellectual property  employed  in its  business, the  Company  is
subject  to the risk of claims alleging infringement of third-party intellectual
property rights. Any such claims could require the Company to spend  significant
sums in litigation, pay damages, develop non-infringing intellectual property or
acquire  licenses to the intellectual property  which is the subject of asserted
infringement. See "Business -- Intellectual Property Rights."
 
FIXED-BID PROJECTS
 
    The Company undertakes certain projects  billed on a fixed-bid basis,  which
is  distinguishable from the Company's principal method of billing on a time and
materials basis,  and  undertakes other  projects  on a  fee-capped  basis.  The
failure  of the Company to complete such projects within budget or below the cap
would expose the  Company to risks  associated with cost  overruns, which  could
have  a material adverse effect on the Company's business, operating results and
financial condition.  See "Management's  Discussion  and Analysis  of  Financial
Condition and Results of Operations -- Overview."
 
LIMITED TRADING HISTORY OF COMMON STOCK; STOCK PRICE VOLATILITY
 
   
    The  Common Stock  first became  publicly traded  on May  3, 1996  after the
Company's initial public  offering at  $16 per share.  Between May  3, 1996  and
August  21, 1996, the  closing sale price has  ranged from a low  of $23 5/8 per
share to a high of $41 1/2 per share. The market price of the Common Stock could
continue to  fluctuate substantially  due  to a  variety of  factors,  including
quarterly fluctuations in results of operations, adverse circumstances affecting
the  introduction or market  acceptance of new products  and services offered by
the Company, announcements of new products and services by competitors,  changes
in  the IT  environment, changes in  earnings estimates by  analysts, changes in
accounting principles, sales of  Common Stock by existing  holders, loss of  key
personnel and other factors. The market price for the Company's Common Stock may
also  be affected by  the Company's ability to  meet analysts' expectations, and
any failure to  meet such  expectations, even if  minor, could  have a  material
adverse  effect on the market price of  the Company's Common Stock. In addition,
the stock  market is  subject to  extreme price  and volume  fluctuations.  This
volatility  has  had a  significant effect  on the  market prices  of securities
issued by many companies for reasons  unrelated to the operating performance  of
these  companies. In  the past,  following periods  of volatility  in the market
price of a company's  securities, securities class  action litigation has  often
been  instituted against such a company.  Any such litigation instigated against
the Company could result  in substantial costs and  a diversion of  management's
attention  and  resources, which  could have  a material  adverse effect  on the
Company's business, operating results and financial condition. See "Price  Range
of Common Stock."

SIGNIFICANT UNALLOCATED NET PROCEEDS
 
    None  of the  anticipated net  proceeds of  this offering  is designated for
specific uses. Therefore, the Board of Directors of the Company will have  broad
discretion  with respect to  the use of  the net proceeds  of this offering. See
"Use of Proceeds."
 
CERTAIN ANTI-TAKEOVER EFFECTS
 
    The Company's  Certificate of  Incorporation and  By-Laws and  the  Delaware
General   Corporation  Law  include  provisions  that  may  be  deemed  to  have
anti-takeover effects and may  delay, defer or prevent  a takeover attempt  that
stockholders  might  consider  in  their best  interests.  These  include By-Law
provisions under which only the Chairman of the Board or the President may  call
meetings  of stockholders and  certain advance notice  procedures for nominating
candidates for election to the Board of Directors. Directors of the Company  are
divided  into three classes and are elected to serve staggered three-year terms.
The Board of  Directors of the  Company is  empowered to issue  up to  3,000,000
shares  of preferred stock  and to determine the  price, rights, preferences and
privileges of such shares, without any further stockholder action. The existence
of this "blank-check" preferred stock could render more difficult or  discourage
an  attempt to obtain control of the Company by means of a tender offer, merger,
proxy contest or otherwise. In addition, this "blank-check" preferred stock, and
any issuance thereof,  may have an  adverse effect  on the market  price of  the
Company's Common Stock. See "Management -- Directors and Executive Officers" and
"Description  of  Capital  Stock  -- Delaware  Law  and  Certain  Certificate of
Incorporation and By-Law Provisions; Anti-Takeover Effects."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
   
    Immediately after  completion  of  this  offering,  the  Company  will  have
10,003,752  shares of  Common Stock outstanding,  of which  the 2,000,000 shares
sold pursuant to  this offering  as well  as the  3,105,000 shares  sold in  the
initial  public offering will be freely tradeable without restriction or further
registration under  the Securities  Act  of 1933,  as amended  (the  "Securities
Act"), except those shares acquired by affiliates of the Company. Holders of the
remaining  shares will  be eligible  to sell  such shares  pursuant to  Rule 144
("Rule 144") under  the Securities Act  at prescribed times  and subject to  the
manner  of sale,  volume, notice and  information restrictions of  Rule 144. The
Company has granted  certain institutional investors  and their transferees  and
Mr.  Szofer  certain  demand  and  piggyback  registration  rights  covering  an
aggregate of 454,574 shares of Common Stock (154,574 shares if the Underwriter's
over-allotment option  is exercised  in full).  In addition,  865,238 shares  of
Common  Stock (88,056 of which are  currently exercisable) are issuable upon the
exercise of outstanding stock options, which shares have been registered by  the
Company under the Securities Act and after issuance upon exercise will be freely
tradeable  without  restriction.  The  Company,  together  with  certain  of its
stockholders (holding in  the aggregate  4,880,626 shares of  Common Stock  upon
consummation of this offering), have agreed not to offer, sell, contract to sell
or  otherwise  dispose of,  directly  or indirectly,  any  Common Stock,  or any
securities convertible into  or exchangeable  or exercisable  for Common  Stock,
until  October  30,  1996, without  the  prior  consent of  Donaldson,  Lufkin &
Jenrette Securities Corporation. Sales of substantial amounts of such shares  in
the  public market  or the  availability of  such shares  for future  sale could
adversely affect  the  market  price of  the  shares  of Common  Stock  and  the
Company's  ability  to raise  additional  capital at  a  price favorable  to the
Company. See "Shares Eligible for Future Sale" and "Underwriting."

                                  THE COMPANY
 
    From its inception in 1984 to December 31, 1995, the Company's business  was
owned  by  Whittman-Hart,  L.P.,  a  Delaware  limited  partnership  ("LP"), and
operated by employees  of Whittman-Hart Corporation  II, a Delaware  corporation
("Corporation  II"), pursuant to a client service agreement. The general partner
of LP was Whittman-Hart, Ltd., a  Delaware corporation ("Limited") of which  94%
was  owned by Mr. Bernard and 6% was owned by Edward Szofer, the Company's Chief
Operating Officer. The limited partners of  LP were Corporation II, Mr.  Bernard
and,  after August 1995,  F-WH Corporation ("Frontenac")  and PVP-WH Corporation
("Platinum"). The stockholders of Corporation  II included officers and  certain
other  employees of the Company. Frontenac and Platinum acquired their interests
in LP  in August  1995 pursuant  to their  purchases of  $4.0 million  and  $1.5
million,  respectively,  of  convertible preferred  equity  units.  See "Certain
Transactions."
 
    Effective  December  31,  1995,  the   Company  restructured  itself  in   a
transaction  (the "Reorganization") pursuant to which  the partners of LP (other
than Corporation II) became the  stockholders of Corporation II, Corporation  II
became  the successor to all  of the assets, liabilities  and business of LP and
the client service  agreement between LP  and Corporation II  was canceled.  The
convertible  preferred and common equity units in  LP were converted into a like
number of shares of Redeemable  Preferred Stock and Common Stock,  respectively,
of  Corporation II, and Corporation II  changed its name to Whittman-Hart, Inc.,
the issuer in this offering.
 
    Prior  to  the  Reorganization,  the  portion  of  the  Company's   earnings
attributable  to the operations of  LP was taxed, for  federal and certain state
income tax purposes, directly to the partners of LP rather than to the  Company.
The  Company has made cash distributions to Mr. Bernard aggregating $179,476 for
the purpose of enabling  him to pay  federal and state  income taxes for  fiscal
1995   attributable  to  LP's  taxable  income,   and  in  connection  with  the
Reorganization  the  Company  declared,  and   in  April  1996  paid,  a   final
distribution  to the Company's predecessor partners aggregating $860,646 for the
purpose of enabling them to pay federal  and state income taxes for fiscal  year
1995  attributable to  LP's taxable  income and to  the tax  consequences of the
Reorganization (collectively, the "Tax Distributions"). From and after the  date
of  the Reorganization, all earnings  of the Company will  be subject to federal
and state corporate income taxes.
 
    The Company maintains its  principal executive offices  at 311 South  Wacker
Drive,  Suite 3500, Chicago,  Illinois 60606. The  Company's telephone number is
(312) 922-9200 and  its Internet address  is http:// www.whittman-hart.com.  The

                                USE OF PROCEEDS
 
   
    The   net  proceeds  to  the  Company  from  the  sale  of  the  Shares  are
approximately $27.8 million, based  on the price  to the public  of $28 1/2  per
share  and after deducting Underwriters' discounts and commissions and estimated
offering expenses. The principal purposes of  this offering are to increase  the
Company's  equity capital and financial  flexibility and provide working capital
to fund the Company's growth strategy. See "Business -- Growth Strategy" and "--
Operational Investments."
    
 
    The Company anticipates that the net proceeds of this offering will be  used
primarily  for  general corporate  purposes,  including working  capital, branch
expansion and  possible acquisitions  of  related businesses.  There can  be  no
assurances  that the Company will open any new  offices or that it will make any
acquisitions. As of the date of this Prospectus, the Company has no  agreements,
understanding  or commitments regarding  the acquisition of  any other business.
Pending such uses,  the Company  intends to invest  the net  proceeds from  this
offering in investment grade, short-term, interest-bearing securities.
 
    The  Company will not  receive any of  the proceeds from  the sale of Common
Stock by the Selling Stockholders. See "Principal and Selling Stockholders."

                                DIVIDEND POLICY
 
    Other than the Tax Distributions made in connection with the Reorganization,
the  Company  has  never  made  any distributions  with  respect  to  its equity
securities. The Company  does not anticipate  paying any cash  dividends on  its
Common  Stock in the foreseeable future. The Company currently intends to retain
future earnings to fund the development and growth of its business.

                     (IN THOUSANDS, EXCEPT PER SHARE DATA)
 
    The following selected financial data for the fiscal years 1991 through 1995
are derived from the  Company's Financial Statements  and related Notes  thereto
that  have been audited  by KPMG Peat Marwick  LLP, independent accountants. The
statements of operations and the balance sheet data as set forth below for,  and
as  of the end  of, each of the  six-month periods ended June  30, 1995 and 1996
have been derived from unaudited financial  statements of the Company which,  in
the opinion of management, include all adjustments that are necessary for a fair
statement of the results of the interim periods, and all such adjustments are of
a  normal recurring nature. The selected financial data for the six months ended

OVERVIEW
 
    Whittman-Hart  is an IT services company that provides strategic IT business
solutions  designed  to  improve  its  clients'  productivity  and   competitive
position.  The Company  was founded in  1984 and has  experienced revenue growth
every year since inception.
 
   
    Whittman-Hart's revenues  are generated  primarily from  professional  fees,
which  are generally billed  at a contracted  hourly rate and  are recognized as
services are provided. Over  the last three  fiscal years, at  least 90% of  the
Company's  revenues  have been  generated  on a  time  and materials  basis. The
Company's services may  also be  provided on  a fixed-bid  or fee-capped  basis,
which  subjects the Company to  the risk of cost  overruns. Fixed-bid revenue is
recognized by the percentage of  completion method. The Company typically  bills
on  a weekly  basis to  monitor client  satisfaction and  manage its outstanding
accounts receivable balances.  The Company's  most significant  cost is  project
personnel  cost, which consists  of consultant salaries  and benefits. Thus, the
Company's financial performance is primarily based upon billing margin (billable
hourly rate less the consultant's  hourly cost) and personnel utilization  rates
(billable hours divided by paid hours).
    
 
    To  date,  the Company  has been  able  to maintain  its billing  margins by
offsetting increases in consultant salaries with increases in its hourly  rates.
Because  most of the  Company's engagements are  on a time  and materials basis,
increases in its cost  of services are generally  passed along to the  Company's
clients  and, accordingly,  do not  have a  significant impact  on the Company's
financial results. In addition,  the Company attempts  to control expenses  that
are not passed through to its clients. Furthermore, profitability is improved by
tying significant incentive compensation to achieving performance goals.
 
    The  Company establishes  standard billing guidelines  based on  the type of
service offered. Actual billing  rates are established on  a project by  project
basis  and may vary from the standard guidelines. Over the last three years, the
Company's average revenue per assignment hour has steadily increased. The growth
in  average  revenue  per  assignment  hour  reflects  a  higher  percentage  of
value-added  services, such  as client/  server software  implementations (E.G.,
SAP),  workgroup  projects  (E.G.,  Lotus  Notes)  and  solutions-oriented   and
strategic consulting projects.
 
    Whittman-Hart  manages its personnel utilization rates by monitoring project
requirements and timetables.  The number  of consultants assigned  to a  project
will  vary  according  to the  size,  complexity,  duration and  demands  of the
project. Project terminations, completions and  scheduling delays may result  in
periods when consultants are not fully utilized. An unanticipated termination of
a  project  could  result  in  a  higher  than  expected  number  of  unassigned
consultants or, if  the Company  were to terminate  such consultants,  increased
severance  expenses. Although  the number  of the  Company's consultants  can be
adjusted to  correspond to  the number  of active  projects, Whittman-Hart  must
maintain  a sufficient number  of senior consultants  to oversee existing client
projects  and  assist  the  Company's   sales  force  in  securing  new   client
assignments.   Whittman-Hart  consultants  are   subject  to  employment-at-will
contracts, which may  be terminated upon  two weeks' notice  without penalty  or
further expense to the Company.
 
    The Company's historical revenue growth is partly attributable to the growth
of its branch network, which consisted of five branch offices and several client
support centers as of December 31, 1995, and an additional branch office, opened
in  Dallas in  the first  quarter of  1996. Each  of the  Company's branches has
 
                                       12

generated annual revenue and gross  profit growth since inception. In  addition,
the  Company has also increased revenues by expanding its existing service lines
to include higher value-added service capabilities, such as SAP and Lotus  Notes
implementation  services, and by increasing the  number of clients billed by the
Company from 338 in 1993 to 492 in 1995.
    
 
    In 1995 the Company made  one-time infrastructure expenditures in the  third
and  fourth quarters totaling $1.1 million.  These expenditures were included in
general and administrative expenses  and were incurred  in connection with:  (i)
developing  a new  employee orientation  program; (ii)  developing the Company's
branch expansion methodology;  (iii) training  the Company's  field task  force,
which  is responsible for  opening the Company's new  branch locations; and (iv)
developing the Company's integrated  marketing campaign, designed to  strengthen
the  Whittman-Hart  brand  name  in  its  branch  locations.  See  "Business  --
Operational Investments."

*Not meaningful.
 
SIX MONTHS ENDED JUNE 30, 1996 COMPARED TO JUNE 30, 1995
 
    REVENUES.  Revenues increased 82% to  $38.9 million in the first six  months
of  1996  from $21.4  million for  the first  six  months of  1995. Each  of the
Company's five established branch offices  experienced revenue growth in  excess
of  75% for the first six months of 1996  as compared to the first six months of
1995. Revenues from the Company's ten most significant clients grew 76%, but  as
a percentage of revenues remained constant at approximately 33%.
 
    GROSS  PROFIT.   Gross profit  consists of  revenues less  cost of services,
which includes consultant salaries and  benefits. Gross profit increased 87%  to
$15.5 million in the first six months of 1996 from $8.3 million in the first six
months of 1995. Gross profit as a percentage of revenues increased to 40% in the
first  six months of  1996 from 39%  in the comparable  1995 period. The Company
continued to benefit from prior investments made in newer branches and  business
units.
 
    SELLING   EXPENSES.    Selling  expenses  include  the  salaries,  benefits,
commissions, travel, entertainment  and all other  direct costs associated  with
the   Company's  direct   sales  force.   Selling  expenses   increased  55%  to
 
                                       13
<PAGE>
$1.7 million in the first six months of 1996 from $1.1 million in the first  six
months of 1995. As a percentage of revenues, selling expenses decreased to 4% in
the  first six  months of 1996  as compared to  5% for the  comparable period in
1995. The decrease is  attributable to a  change in the  structure of the  sales
commission  plan. Selling expenses  have a large  variable component relating to
revenue growth, and therefore  are expected to remain  relatively constant as  a
percentage of revenues in the future.
 
    RECRUITING EXPENSES.  Recruiting expenses consist of costs related to hiring
new  personnel. These  costs include the  salaries, benefits,  bonuses and other
direct costs of  in-house recruiters,  outside recruiting  agency fees,  sign-on
bonuses,  relocation fees  and advertising costs.  Recruiting expenses increased
58% to $1.6 million  in the first six  months of 1996 from  $1.0 million in  the
first  six  months of  1995. As  a percentage  of revenues,  recruiting expenses
decreased to 4% in the first six months  of 1996 from 5% in the comparable  1995
period.  The number of consultants increased 69% to 718 as of June 30, 1996 from
425 as of June 30, 1995, while total recruiting costs per hire remained constant
at approximately $5,700.
 
    GENERAL AND ADMINISTRATIVE  EXPENSES.  General  and administrative  expenses
include  salaries and benefits  of management and  support personnel, facilities
costs, training,  travel, outside  professional fees  and all  other branch  and
corporate  costs.  General and  administrative  expenses increased  83%  to $9.6
million in the  first six  months of  1996 from $5.3  million in  the first  six
months  of 1995. The increase is primarily attributable to a general increase in
corporate costs  (approximately  25% of  such  increase), increased  numbers  of
branch  management personnel  to support  the growth  of new  business units and
newer branch locations (approximately 14% of such increase), increased  personal
computer  leasing  due  to  the  rollout  of  laptop  computers  for consultants
(approximately 19%  of such  increase) and  the establishment  of a  new  Dallas
branch office (approximately 13% of such increase). As a percentage of revenues,
general and administrative costs remained constant at 25%.
 
   
    OTHER  INCOME (EXPENSE).   Other income (expense)  increased $0.4 million in
the first six months of 1996 as  compared to the comparable period in 1995.  The
increase  is  primarily  attributable  to  interest  earned  on  investments  of
available net proceeds from the Company's initial public offering.
    
 
   
    INCOME TAXES.  Income tax expense  was $1.1 million (effective rate of  39%)
in  the first six months of 1996 as  compared to $0.3 million (effective rate of
37%) provided on a  pro forma basis in  the first six months  of 1995. Prior  to
December  31, 1995,  the Company  operated as a  partnership. The  pro forma tax
adjustment for the first  six months of 1995  represents federal and  additional
state  income tax expense that would have been required had the Company operated
as a C corporation during that period.
    
 
1995 COMPARED TO 1994
 
    REVENUES.   Revenues increased  69%  to $49.8  million  in 1995  from  $29.5
million  in 1994. Each of the  Company's five branch offices experienced revenue
growth in excess of 50% for 1995  compared to 1994. Revenues from the  Company's
ten  most significant clients  grew 67%, but  as a percentage  of total revenues
remained constant  at approximately  33%. Expansion  of the  Company's  existing
service  offerings,  primarily  client/server,  business  consulting  and Novell
LAN/WAN networking  services, accounted  for approximately  75% of  the  revenue
increase,  while the addition of new service  offerings such as SAP, Lotus Notes
and enterprise services accounted for the remaining 25% of the revenue increase.
 
    GROSS PROFIT.   Gross profit  increased 64% to  $19.4 million  in 1995  from
$11.8  million in 1994. Gross profit as a percentage of revenues declined to 39%
in 1995 from  40% in 1994.  This decrease  is attributable to  the 16%  start-up
margin  associated with  the Company's  new SAP  practice, which  is expected to
yield  higher  margins  in  the  future.  Excluding  the  low  start-up  margins
associated  with the SAP practice, 1995 gross profit as a percentage of revenues
would have been 40%.
 
    SELLING EXPENSES.  Selling  expenses increased 74% to  $2.5 million in  1995
from  $1.4 million in 1994.  The Company's selling expenses,  as a percentage of
revenues, remained constant at approximately 5%.
 
    RECRUITING EXPENSES.  Recruiting expenses  increased 95% to $2.2 million  in
1995  from  $1.1 million  in  1994, but  as  a percentage  of  revenues remained
constant   at   4%.    This   increase    in   recruiting    expenses   was    a
 
                                       14
<PAGE>
result  of  expanded hiring  activity  in preparation  for  anticipated employee
requirements in  1996. The  number of  consultants increased  69% to  511 as  of
December 31, 1995 from 302 as of December 31, 1994, while total recruiting costs
per hire remained constant at approximately $6,500.
 
    GENERAL  AND ADMINISTRATIVE  EXPENSES.  General  and administrative expenses
increased 61% to $13.0 million in 1995 from $8.1 million in 1994. This  increase
is  primarily  attributable  to  significant  one-time  infrastructure additions
(approximately 22% of  such increase),  the establishment of  new corporate  and
Chicago branch office facilities (approximately 17% of such increase), increased
personal  computer leasing (approximately 16%  of such increase) and development
of a new SAP business unit (approximately 9% of such increase). As a  percentage
of  revenues, general and  administrative expenses declined to  26% in 1995 from
27% in 1994.
 
    The one-time infrastructure  additions in  1995 were made  primarily in  the
fourth  quarter to support significantly  higher anticipated growth. These costs
included  the  establishment  of  a   branch  expansion  team,  additional   SAP
investments  and the development of the Company's integrated marketing campaign.
Excluding these $1.1 million charges to general and administrative expenses, the
Company's general and  administrative expenses  as a percentage  of revenues  in
1995 would have been 24%.
 
1994 COMPARED TO 1993
 
    REVENUES.    Revenues increased  26%  to $29.5  million  in 1994  from $23.4
million  in  1993.   The  Company's  largest   branch  locations,  Chicago   and
Indianapolis,  grew  by approximately  20%. The  Denver and  Milwaukee branches,
which were opened in 1993, experienced combined revenue growth of  approximately
180%.  The opening of the Cincinnati branch in the second half of 1994, combined
with the establishment of  two additional client  support centers in  Evansville
and Peoria, contributed an additional $1.0 million to revenues. During 1994, the
Company  continued to  expand its service  offerings and  geographical reach and
increase its number of client relationships, which reduced the share of revenues
from its ten  most significant  clients. Revenues  from the  Company's ten  most
significant  clients, expressed as  a percentage of  total revenues, declined to
34% in 1994 from 49% in 1993.
 
    GROSS PROFIT.  Gross profit increased 23% to $11.8 million in 1994 from $9.6
million in 1993. Gross  profit as a  percentage of revenues  declined to 40%  in
1994  from 41% in  1993. This decrease was  a result of  the higher direct costs
associated with the  Chicago branch's  establishment of two  new practice  areas
(client  server and electronic  commerce) as well  as additional expenditures to
establish  more  specialized  subgroups  within  its  Business  Consulting   and
Documentation and Training business units.
 
    SELLING  EXPENSES.  Selling  expenses increased 33% to  $1.4 million in 1994
from $1.1  million  in 1993.  As  a  percentage of  revenues,  selling  expenses
remained relatively constant at 5%.
 
    RECRUITING  EXPENSES.  Recruiting expenses increased  46% to $1.1 million in
1994 from $0.8 million in 1993 and  as a percentage of revenues increased to  4%
in  1994 from  3% in  1993. This increase  in recruiting  expenses resulted from
expanded hiring  activity  in  the  second  half  of  1994  in  preparation  for
anticipated  employee requirements in 1995.  The number of consultants increased
33% to 302 as of December 31, 1994 from 227 as of December 31, 1993, while total
recruiting costs  per  hire  decreased  to approximately  $6,500  in  1994  from
approximately $7,100 in 1993.
 
    GENERAL  AND ADMINISTRATIVE  EXPENSES.  General  and administrative expenses
increased 20% to $8.1 million in 1994 from $6.7 million in 1993. The increase is
primarily attributable  to  the development  of  internal systems  and  networks
(approximately  21% of such increase), expanded marketing efforts (approximately
18% of such increase),  higher travel related costs  (approximately 18% of  such
increase)  and increased computer spending (approximately 16% of such increase).
As a percentage of revenues, general and administrative expenses declined to 27%
in 1994 from 29% in 1993.

    The  Company has achieved revenue growth in each of its last eight quarters.
Variations in the Company's  revenues and operating results  occur from time  to
time  as a  result of a  number of factors,  such as the  significance of client
engagements commenced and  completed during  a quarter, the  number of  business
days  in a quarter, timing of branch  and service line expansion activities, the
timing of corporate expenditures and employee hiring and utilization rates.  For
example,  operating  income  decreased to  $0.3  million for  the  quarter ended
December 31, 1995  from $0.6  million in the  prior quarter.  This decrease  was
principally  a  result of  the commencement  of  $1.1 million  in infrastructure
expenditures. Despite the significant number of holidays in the fourth  quarter,
the Company's results are largely unaffected because its compensation plans have
been  designed to reward  participants based on the  achievement of their annual
profit goals.

LIQUIDITY AND CAPITAL RESOURCES
 
    Prior to its  initial public  offering in  May 1996,  the Company's  primary
source  of liquidity had been operating  cash flow, periodically supplemented by
borrowings under  the Company's  revolving  credit and  term facilities  with  a
commercial  bank. The Company has a Loan  Agreement under which it may apply for
up to $5.0 million of  credit with interest, at  the Company's option, at  LIBOR
plus  1.5% or the lender's prime rate.  There were no borrowings under this Loan
Agreement as of July 31, 1996. The Company's Loan Agreement expires on April 30,
1997.
 
    On May 8,  1996, the  Company completed an  initial public  offering of  its
Common  Stock which resulted in net proceeds  to the Company of $37.8 million. A
portion of the proceeds from the initial public offering were used to retire the
Company's term facilities. The Company believes  the net proceeds from the  sale
of  Common Stock offered hereby, together with existing sources of liquidity and
funds generated  from  operations,  will  provide  adequate  cash  to  fund  its
anticipated  cash  needs, including  funding the  Company's growth  strategy, at
least through the next twelve months.
 
RECENTLY ISSUED FINANCIAL ACCOUNTING STANDARDS
 
    Statement  of  Financial  Accounting  Standards  No.  123,  Accounting   for
Stock-Based  Compensation,  was  issued in  October  1995. The  Company  will be
required to adopt  the new standard  no later than  fiscal 1996, although  early
adoption  is permitted.  This standard establishes  the fair  value based method
(the "FAS  123 Method")  rather than  the intrinsic  value based  method as  the
preferred  accounting  methodology  for  stock-based  compensation arrangements.
Entities are  allowed  to:  (i)  continue  to  use  the  intrinsic  value  based
methodology in their basic financial statements and provide in the footnotes pro
forma net income and earnings per share information as if the FAS 123 Method had
been  adopted; or (ii) adopt the FAS 123  Method. Adoption of the FAS 123 Method
would result in higher compensation cost for the Company.

SUMMARY
 
    Whittman-Hart is  an information  technology  ("IT") services  company  that
provides  strategic  IT  business  solutions designed  to  improve  its clients'
productivity and competitive position. The  Company offers its clients a  single
source  for a comprehensive  range of services  required to successfully design,
develop and implement integrated computer systems projects in the client/server,
open systems, midrange and mainframe computing environments. Among the  services
offered  by the Company are systems integration, strategic IT planning, software
development, packaged software implementation (such as SAP's R/3 client/  server
application  software),  business process  reengineering,  organizational change
management,   networking   and   connectivity,   conventional   and   multimedia
documentation  and training,  design and  implementation of  workgroup solutions
(such as  Lotus Notes)  and  design and  implementation of  electronic  commerce
solutions  (such  as  intranet/Internet and  electronic  data  interchange). The
Company  believes   this   breadth   of  services   fosters   long-term   client
relationships,  affords cross-selling opportunities  and minimizes the Company's
dependence on any single technology.
 
    Whittman-Hart's marketing efforts focus  on middle market companies  ranging
from  $50 million to  $500 million in  annual revenues and  divisions of Fortune
1000 companies. Whittman-Hart  serves clients  in a broad  range of  industries,
including communications, consumer products, distribution, diversified services,
financial  services,  insurance,  manufacturing,  pharmaceuticals,  professional
services, retail and technology. The  Company employs consultants with  business
experience in these areas to enhance its ability to understand industry-specific
business  issues and develop unbiased IT  solutions to address these issues. The
number of clients billed by  the Company in a given  year has grown from 338  in
1993 to 492 in 1995. Many of these clients have maintained ongoing relationships
with  Whittman-Hart  over multiple  years, spanning  a  variety of  projects and
services. The  Company  believes that  it  has established  significant  ongoing
relationships with many of its clients.
 
    The demand for IT consulting services has increased rapidly in recent years.
Whittman-Hart  has  competed successfully  in  this environment,  experiencing a
compound annual revenue growth rate of 46% over the past three fiscal years. For
fiscal year 1995, Whittman-Hart's  revenues were $49.8  million, an increase  of
69%  from $29.5 million in  fiscal year 1994. For the  six months ended June 30,
1996, the Company's revenues were $38.9  million, an increase of 82% from  $21.4
million  in the corresponding 1995 period. From  June 30, 1995 to June 30, 1996,
the number of consultants increased 69% from 425 to 718.
 
    Whittman-Hart sells  and delivers  its  services through  a network  of  six
branch  offices located in Chicago,  Indianapolis, Milwaukee, Denver, Cincinnati
and Dallas. Based on its experience operating the existing branches, the Company
has developed a  branch expansion model.  The Company intends  to leverage  this
model  through  its national  branch expansion  strategy.  The Company  opened a
Dallas branch in January 1996, and an additional branch is scheduled to open  in
late 1996. In support of its growth strategy, Whittman-Hart has made significant
investments in its business and systems infrastructure, recruiting organization,
training methodologies and marketing programs, all of which the Company believes
will be necessary to support a significantly larger organization.
 
INDUSTRY BACKGROUND
 
    Many   businesses  today   are  facing   intense  competition,  accelerating
technological change,  personnel  downsizing  and  widespread  business  process
reengineering.  Increasingly,  these companies  are turning  to IT  solutions to
address these issues and to compete  more effectively. As a result, the  ability
of  an organization  to integrate  and deploy  new information  technologies has
become critical.
 
    Although many companies  have recognized  the importance of  IT systems  and
products  to  compete  in  this  business  climate,  the  process  of designing,
developing and  implementing  IT  solutions  has  become  increasingly  complex.
Companies  are continuing  to migrate  away from  centralized mainframes running
proprietary software  toward  decentralized,  scalable  architectures  based  on
personal  computers, client/server architectures, local  and wide area networks,
shared databases and packaged application software. These
 
                                       18
<PAGE>
advances have greatly  enhanced the  ability of  companies to  benefit from  the
application  of IT. Consequently, the number of  companies desiring to use IT in
new ways  and the  number of  end users  within these  organizations are  rising
rapidly.
 
    As  a result  of the  variety and complexity  of these  new technologies, IT
managers must integrate  and manage  "open systems"  and "distributed  computing
environments"  consisting  of multiple  computing platforms,  operating systems,
databases and networking  protocols, and must  implement off-the-shelf  software
applications  to support  business objectives.  Companies must  also continually
keep pace  with new  developments,  which often  render existing  equipment  and
internal  skills  obsolete. At  the same  time,  external economic  factors have
forced organizations to focus on core competencies and trim workforces in the IT
management area. Accordingly,  these organizations  often lack  the quantity  or
variety  of IT skills necessary to design  and develop IT solutions. IT managers
are charged with developing and  supporting increasingly complex IT systems  and
applications  of  significant  strategic value  while  working  under budgetary,
personnel and expertise constraints within their own organizations.
 
    Due  to  the   foregoing  factors,   demand  for  IT   services  has   grown
significantly.  According  to  industry  sources, the  worldwide  market  for IT
services was estimated at $185 billion in 1995, with a projected market of  $292
billion  for 2000. The domestic IT services market is projected to grow from $75
billion in 1995  to $130 billion  in 2000. Currently,  substantially all of  the
Company's  revenues are derived from IT  consulting and planning services and IT
implementation and  integration services,  two segments  within the  overall  IT
services  industry. It is  estimated that the domestic  market for IT consulting
and planning services will nearly double from roughly $9 billion in 1995 to more
than $18 billion in  2000. The worldwide market  for IT consulting and  planning
services  is estimated to have been $20 billion  in 1995, with a forecast of $38
billion by 2000.  Domestic IT implementation  and integration services  revenues
are  estimated to have been $20 billion in  1995, with a forecast of $35 billion
by 2000. The worldwide market for IT implementation and integration services  is
estimated  to have been $49  billion in 1995, with a  forecast of $81 billion by
2000.
 
    The Company believes the demand for IT services is particularly strong among
middle market companies, which typically  lack the time and technical  resources
to  satisfy all of their IT needs internally. These companies must often rely on
IT service providers to help implement  and manage their systems. However,  many
middle  market companies  must rely  on multiple  providers for  their IT needs.
Generally, larger IT service providers do not target these companies and smaller
IT service  providers often  lack  sufficient breadth  of services  or  industry
knowledge  to satisfy these companies' needs. The Company believes this reliance
on multiple  service providers  creates multiple  relationships which  are  more
difficult and less cost-effective to manage and can adversely impact the quality
and  compatibility of IT  solutions. Further, many  smaller IT service providers
have a  financial incentive  to  recommend a  particular hardware  and  software
provider, which may not be optimal or best of breed for the client's IT problem.
 
THE WHITTMAN-HART SOLUTION
 
    The Whittman-Hart solution is designed to enable middle market companies and
divisions of Fortune 1000 companies to use IT as a more effective business tool.
The following are key attributes of the Whittman-Hart solution:
 
    SOLVE  CRITICAL  BUSINESS PROBLEMS.   The  Company  focuses on  providing IT
solutions  that   address  strategic   business  issues,   such  as   increasing
productivity,  reducing costs,  improving customer  service and  using data more
effectively. To maintain  this focus, Whittman-Hart  employs senior  consultants
and  other professionals  who have  relevant experience  in specific industries,
including communications, consumer products, distribution, diversified services,
financial  services,  insurance,  manufacturing,  pharmaceuticals,  professional
services,  retail  and  technology.  In addition  to  this  industry  focus, the
Company's professionals provide a  high level of  technical competency. To  this
end,  Whittman-Hart has developed  systems, methodologies and  an environment to
attract, develop, motivate and retain  professionals with the highest levels  of
technical skills.
 
    PROVIDE  WIDE  RANGE OF  IT  SERVICES.   Because  many of  its  clients have
multiple IT needs, the  Company provides a  wide range of  IT services that  are
organized  under  nine  individual  business  units,  with  each  business  unit
addressing a  specific area  of  IT and  specific  IT problems.  This  structure
enables the Company
 
                                       19
<PAGE>
to  be a single source provider of  IT services while maintaining advanced skill
sets offered by each business unit.  In response to the rapidly changing  nature
of IT, the Company regularly evaluates emerging technologies and their potential
benefit  as new services to clients. Based on these evaluations, the Company may
develop additional  business  units or  expand  the service  lines  of  existing
business  units to enhance the Company's ability to support its clients' ongoing
IT requirements.
 
    OFFER LOCAL  PRESENCE.   By delivering  its services  to clients  through  a
geographically dispersed branch network, the Company demonstrates its commitment
to  each local market and enhances its ability to attract skilled, locally-based
consultants. This  branch  network also  increases  efficiencies to  clients  by
enhancing   responsiveness   and   minimizing   travel   expense.   Furthermore,
Whittman-Hart  believes  that  local  branch  offices  establish  greater   name
recognition  for the Company and increase  referrals for its services within the
potential client base in that locale. As a result, the Company believes it has a
competitive advantage when competing against firms that do not maintain a  local
presence.
 
    IMPLEMENT  UNBIASED SOLUTIONS.  To ensure its clients receive the optimal IT
solution for their  business needs,  the Company implements  solutions that  are
unbiased  as to specific  hardware or software providers.  The Company offers an
objective viewpoint and assessment of  the advantages and disadvantages of  each
particular  IT solution, including packaged software applications, platforms and
operating systems. Consistent with this approach, the Company avoids the bias of
generating significant revenue from promoting third-party products. By  offering
its services independently, Whittman-Hart is able to take a flexible approach to
its  clients'  business  problems and  provide  them  with a  best  of  breed IT
solution.
 
GROWTH STRATEGY
 
    The Company's goal  is to become  its clients' preferred  and single  source
provider  of a wide range of IT services. The Company's strategy to achieve this
goal includes the following elements:
 
    EXPAND GEOGRAPHIC  PRESENCE.    Whittman-Hart plans  to  expand  by  opening
additional  branches  in  targeted  geographic locations.  The  Company  uses an
evaluation methodology  to  identify  cities that  possess  the  characteristics
needed  to support a successful branch  operation. The Company believes at least
25 domestic cities satisfy its branch  expansion criteria. The Company opened  a
Dallas  branch in January 1996, and an additional branch is scheduled to open in
late  1996.  In  addition,  the  Company  plans  to  begin  evaluating  selected
international markets during 1996.
 
    BROADEN  SERVICE LINES.   Whittman-Hart  believes that  it can  increase its
revenues from existing clients and attract new clients by expanding its range of
IT services. To advance this strategy, the Company maintains a Technology Review
Board that is responsible  for identifying, evaluating  and recommending new  IT
service  opportunities. Recent  additions to  the service  line have  focused on
value-added services, including intranet services within the Electronic Commerce
business unit (added in 1996) and other services within the Company's  Workgroup
Technologies  and SAP Center  of Expertise business units  (both added in 1995).
The Company plans  to add new  business units and  expand the service  offerings
within  its existing business units  in order to offer  clients access to a more
comprehensive range of services.
 
    LEVERAGE EXISTING CLIENT BASE.  Whittman-Hart believes it can sustain growth
in its  existing branches  by  continuing to  establish and  maintain  long-term
client  relationships. The  access and  goodwill offered  by these relationships
provide  the  Company  with  significant  advantages  over  its  competitors  in
marketing  additional services and  solutions to such  clients. The Company also
believes its long-term client relationships and ability to address its  clients'
needs throughout the life cycle of their IT systems distinguish the Company from
many  of  its competitors  and  provide the  opportunity  to become  a preferred
provider of IT solutions for a broad range of its existing and new clients.
 
    PURSUE STRATEGIC ACQUISITIONS AND AGREEMENTS WITH BUSINESS PARTNERS.   Given
the  highly  fragmented  nature  of the  IT  services  marketplace,  the Company
believes significant  acquisition  opportunities  exist.  On  an  ongoing  basis
Whittman-Hart  evaluates potential  acquisition candidates to  expand its branch
office network, increase  its technical expertise  or provide other  competitive
advantages.  In addition, Whittman-Hart may seek to form strategic relationships
with business partners to share technical and industry
 
                                       20

knowledge and pursue joint marketing opportunities. The Company has  established
business  partner relationships  with SAP America,  Inc., International Business
Machines Corporation,  Lotus Corporation,  Microsoft Corporation,  Novell,  Inc,
Oracle  Corporation  and Sybase,  Inc. These  relationships typically  allow the
Company to gain access to training, product support and the technology developed
by these  partners. The  training  programs often  enable Company  employees  to
become  certified in a given technology. Establishing these relationships allows
the Company  to use  the  business partner's  name  and the  "business  partner"
designation  in  marketing  the  Company's  services.  These  relationships also
facilitate the Company's  pursuit of marketing  opportunities with the  business
partners.
 
    The  business  partner  relationships  do not  require  the  Company  to use
technology developed by the business  partners in implementing IT solutions  for
clients. Nonetheless, the Company may be retained by a client based in part upon
one  or  more  of the  Company's  business partner  relationships.  Although the
Company is not obligated to resell products offered by the business partners, in
the event it does so, it is generally entitled to purchase discounts on products
purchased for resale.  It is  the Company's current  practice to  pass any  such
discounts on to the clients to whom the business partner products are resold.
 
OPERATIONAL INVESTMENTS
 
    Over  the past several years, the Company has invested in the development of
systems,  methodologies,  training  programs  and  infrastructure.  The  Company
believes  that  it is  positioned to  leverage these  investments into  a larger
organization. Whittman-Hart is pursuing its strategy to become a leading  single
source  provider of  IT services  through a  diverse national  branch network by
utilizing the following operational investments:
 
    GEOGRAPHIC  EXPANSION  MODULE.    Under  Whittman-Hart's  branch   expansion
methodology   and  related  database,  the  Company  evaluates  and  prioritizes
geographic markets  based  on,  among  other things,  the  estimated  number  of
potential  clients and the  overall business environment.  This methodology also
identifies the  appropriate  mix  of  service offerings  in  such  markets.  The
implementation phase of the expansion module is managed by a field task force, a
team  of  professionals representing  each of  the major  functions of  a branch
office who relocate  to the new  site before  and during the  branch opening  in
order  to efficiently  replicate the Company's  branch model  and assure ongoing
compliance with the  Company's policies, procedures  and performance  standards.
This  methodology includes an automated tracking system that enables the Company
to monitor project status and control project expenses.
 
    RECRUITING MODULE.   In order  to address  the strong  demand for  qualified
consultants  in the IT services industry, the Company has developed a recruiting
system and database that facilitates the rapid identification of  skill-specific
employee   candidates  and  the  efficient  processing  of  a  large  number  of
applicants. This  system resulted  in a  reduction in  recruiting expenses  from
approximately  $7,100 per hire in 1993 to approximately $6,500 per hire in 1995.
During this period, the  number of recruiting personnel  increased from four  to
fifteen.
 
    PROPRIETARY  TRAINING  MODULE.   Whittman-Hart  has invested  in  a training
curriculum and methodology  known as the  Whittman-Hart Institute for  Strategic
Education  ("WHISE"). The Company employs a "virtual" university approach to its
training  by  using  conventional  university  teaching  methods  while   taking
advantage  of  multimedia  and computer-based  training  and tools,  as  well as
self-study programs. The Company believes  the WHISE curriculum and  methodology
enable it to train employees efficiently and effectively.
 
    INFORMATION  SYSTEMS.   In order to  enhance the efficiency  of its business
operations, Whittman-Hart has invested in the Whittman-Hart Information Network,
a  Lotus  Notes-based  collection  of  integrated  applications,  including   an
executive  information  system, a  prospect  database, a  proposal  tracking and
development system,  e-mail  and  a  wide-area  network  linking  the  Company's
employees  through remote access. Substantially  all of the development expenses
for these information systems have been incurred.
 
    INTEGRATED MARKETING CAMPAIGN.   The  Company has designed  and produced  an
integrated  marketing campaign,  including a series  of radio,  print and direct
mail advertisements,  collateral  materials  and  the  Company's  Internet  site
(http://www.whittman-hart.com).  The  campaign  is  designed  to  strengthen the
 
                                       21
<PAGE>
Whittman-Hart brand  name  and generate  new  clients and  employee  candidates.
Substantially  all  of  the development  expenses  have been  incurred  for this
marketing program, which  can be  deployed on  a market-by-market  basis as  new
branches are opened.
 
SERVICES
 
    Whittman-Hart  offers its clients a single  source for a comprehensive range
of IT services required to successfully design, develop and implement integrated
IT solutions in  diverse computing  environments. These  services are  delivered
through the Company's nine business units, which consist of Business Consulting,
IT   Architecture,  IT  Services,  IT  Engineering,  SAP  Center  of  Expertise,
Electronic Commerce,  Workgroup  Technologies, Documentation  and  Training  and
Integrated  Services.  In  addition,  through its  Technology  Review  Board the
Company regularly evaluates emerging IT services and new software products  and,
based on its findings, may add new business units or expand the service lines or
skill sets of existing business units.
 
    The  Company  believes that  successful  implementation of  a  major systems
project requires a  wide range  of skills  and a  comprehensive methodology  for
delivering  these skills in an efficient  and effective manner. Accordingly, the
Company employs senior consultants who possess industry-specific knowledge and a
broad range of  technical expertise. In  addition, the Company  has developed  a
methodology  for delivering  these skills, which  includes in-depth consultation
with the  client  and  development  of a  well-defined  blueprint  and  specific
timetable  for the  project. To coordinate  these skills,  the Company's Primary
Relationship Manager ("PRM") acts as an  advisor and liaison between the  client
and the members of each of the Company's business units involved in the project.

    Whittman-Hart's clients consist primarily of middle market companies ranging
from  $50 million to  $500 million in  annual revenues and  divisions of Fortune
1000 companies. The number of clients billed by the Company in a given year  has
grown  from 338 in  1993 to 492 in  1995. Many of  these clients have maintained

    Examples of Whittman-Hart's major engagements include the following:
 
    ENTERPRISE-WIDE   IMPLEMENTATION   OF  SAP'S   R/3  SOFTWARE   FOR  COMPUTER
PERIPHERALS DISTRIBUTOR.   An international distributor  of peripheral  computer
equipment  determined  that  its existing  IT  systems did  not  meet functional
requirements and could not support the Company's growth strategy.  Whittman-Hart
was  engaged to  work with  management to  rapidly develop  and implement  a new
system based on SAP's R/3 software  product and an Oracle database operating  on
an  HP UNIX platform with a Banyan  Vines Network. Timing was critical since the
IT solution  had  to  support  new product  lines  scheduled  for  introduction.
Although  SAP  implementations generally  require 7  to  24 months  to complete,
Whittman-Hart was retained  to deliver  the enterprisewide solution  in only  90
days.   Whittman-Hart  used  its  rapid   implementation  methodology,  and  its
 
                                       27
<PAGE>
consultants' business experience,  to work  with management  to define  business
requirements,  to identify the  SAP modules to implement  and to help reengineer
the client's  business  processes. In  45  days, Whittman-Hart  delivered  fully
configured prototypes of the client's key financial, distribution and management
modules.  During the remaining  45 days, Whittman-Hart  worked with the client's
MIS department in  executing data conversion,  integration testing and  end-user
training  to  maximize productivity  and  user acceptance  of  the system.  As a
result, Whittman-Hart  helped  the client  implement  a flexible,  scalable  and
integrated solution on time and on budget.
 
    INTEGRATION  OF INFORMATION  TECHNOLOGIES FOR  INTERNATIONAL OFFICE PRODUCTS
DISTRIBUTOR.   An  international direct  mail  and office  products  distributor
retained  Whittman-Hart for  several strategic  technology projects. Consultants
from Whittman-Hart's Business Consulting,  IT Architecture, IT Engineering,  and
Electronic  Commerce business units were deployed  to implement new order entry,
inventory control and product  shipping software. Concurrently,  Whittman-Hart's
IT architects guided the re-design and migration of the client's IT systems from
a  mainframe  environment to  a midrange,  distributed network  environment. The
implemented software  provided integrated  management  of inventory  within  the
client's  national network of warehouses and improved customer service and order
fill  rates.  Whittman-Hart   Electronic  Commerce   consultants  designed   and
implemented  an  EDI system  to integrate  vendors  with the  client's inventory
management system.  The  Company's IT  engineers  designed and  implemented  the
AS/400 and LAN communications systems and enhanced the order entry system to use
CD-ROM  technology to  enable customers  to directly  order products  from their
desktops.  Whittman-Hart's   Electronic  Commerce   consultants  currently   are
converting  the client's  CD-based catalogue into  an Internet  version based on
World Wide Web technology.
 
    DEVELOPMENT OF  LOTUS NOTES-BASED  SALES  SUPPORT APPLICATION  FOR  SERVICES
PROVIDER.    A  major  services  provider  engaged  Whittman-Hart  to  develop a
comprehensive sales  and  marketing support  application  using Lotus  Notes  to
streamline   its  sales  process   and  enhance  sales   and  customer  service.
Whittman-Hart's Workgroup consultants,  with guidance  and support  from its  IT
Architecture  consultants,  designed the  application  and managed  the project.
Whittman-Hart's  IT  Services  consultants  performed  front-end  and   back-end
database  application development  in Visual  Basic and  data migrations between
Oracle and  Lotus Notes  databases. Whittman-Hart's  Documentation and  Training
consultants  developed and  implemented a program  to train more  than 400 users
located in a five-state region on  the new application in a seven-month  period.
The  new  application  retrieves  data from  several  legacy  systems (primarily
mainframes), centralizes the collection and distribution of account information,
allows for remote access  by system users,  fosters communication between  sales
teams and departments and facilitates better account management.
 
SALES AND MARKETING
 
    Whittman-Hart  markets and provides its services directly through its branch
offices and client support centers. In addition, Whittman-Hart has developed and
tested an  advertising campaign  in its  branch markets.  The campaign  includes
print,  direct mail and  radio advertising, combined  with local seminars, trade
shows, public relations and collateral materials.
 
    Sources of  new client  relationships include  referrals, telemarketing  and
Whittman-Hart's  integrated marketing campaign. The Company's sales organization
is supported by its prospect database, which includes the names of companies and
decision makers  in  each targeted  geographic  market. This  proprietary  Lotus
Notes-based  information system,  a component  of the  Whittman-Hart Information
Network, also  allows Whittman-Hart  employees to  access the  Company's  skills
database and project portfolio.
 
    Whittman-Hart  account executives establish  contact with targeted prospects
to create  awareness,  understanding and  preference  for the  Company.  Account
executives  also identify general client needs  and introduce the appropriate IT
consultant or team of IT  consultants led by a PRM  to help develop the  initial
proposal.  The PRM, typically a senior level manager, is assigned to the account
to establish a long-term  relationship. The PRM serves  as the client's  primary
source  of IT advice and overall coordinator of Whittman-Hart's multiple service
offerings to the client.
 
                                       28
<PAGE>
    In addition to its  branch locations, the  Company maintains several  client
support  centers. These  centers consist  of small  offices, usually  located in
smaller or more remote markets, which the Company maintains to support the needs
of an existing client or clients near that location.
 
HUMAN RESOURCES
 
   
    The Company's success  depends in large  part upon its  ability to  attract,
develop,  motivate  and  retain highly  skilled  technical  employees. Qualified
technical employees  are in  great demand  and are  likely to  remain a  limited
resource   for  the  foreseeable  future.  Whittman-Hart  dedicates  significant
resources to  recruiting  consultants  with  both  IT  consulting  and  industry
experience.  Many  consultants  are selected  from  among the  largest  and most
successful IT, accounting  and other professional  services organizations.  Each
candidate  is screened through detailed interviews by Whittman-Hart's recruiting
personnel,  technical   interviews   by   consultants  and   an   appraisal   by
Whittman-Hart's   managers.  As   of  July   31,  1996,   the  Company  employed
approximately 915 employees, of whom approximately 770 were consultants.
    
 
    Whittman-Hart has  implemented  a  number  of  distinctive  human  resources
programs.  For example,  the Company's  performance-based incentive compensation
program provides guidelines  for career development,  encourages development  of
skills,  provides  a  tool  to  manage  the  employee  development  process  and
establishes compensation guidelines. Whittman-Hart has also developed its  WHISE
training  module  to  guide  consultants  through  a  progression  of  skill and
competency development programs. As part of this module, the Company  reimburses
employees for education and training, provides computer-based training curricula
and  provides access to the Company's Technology Center where employees can gain
hands-on experience with a diverse array of computing environments. In addition,
Whittman-Hart has developed a centralized new employee orientation program  that
features  multimedia presentations  and a  computer-based training  program. See
"Business -- Operational Investments -- Proprietary Training Module."
 
    None of  the Company's  employees  are subject  to a  collective  bargaining
arrangement.   Whittman-Hart  has  entered  into  employment  agreements,  which
(without substantial  penalty)  are  terminable  upon  two  weeks  notice,  with
virtually  all  of  its  sales, recruiting  and  technical  personnel containing
noncompetition,  nondisclosure  and  nonsolicitation  covenants.  Although  most
consultants  are  Company  employees,  the Company  does  engage  consultants as
independent contractors from time to time.
 
COMPETITION
 
    The market  for IT  services  includes a  large  number of  competitors,  is
subject  to rapid change and is  highly competitive. Primary competitors include
participants from a variety of  market segments, including "Big Six"  accounting
firms,  systems consulting and implementation firms, application software firms,
service groups of computer equipment companies, facilities management companies,
general management consulting  firms and  programming companies.  Many of  these
competitors  have  significantly  greater  financial,  technical  and  marketing
resources and  greater  name recognition  than  the Company.  In  addition,  the
Company  competes with its clients' internal resources, particularly where these
resources represent a  fixed cost  to the  client. Such  competition may  impose
additional pricing pressures on the Company. See "Risk Factors -- Competition."
 
    The  Company  believes  that the  principal  competitive factors  in  the IT
services market  include  breadth  of  services  offered,  technical  expertise,
knowledge  and experience  in the industry,  price, perceived  value, quality of
service and responsiveness to client needs and speed in delivering IT solutions.
 
INTELLECTUAL PROPERTY RIGHTS
 
    Whittman-Hart's success has  resulted, in part,  from its methodologies  and
other  proprietary  intellectual  property  rights. The  Company  relies  upon a
combination of  nondisclosure  and  other  contractual  arrangements  and  trade
secret,  copyright and trademark laws to  protect its proprietary rights and the
proprietary rights of third parties from whom the Company licenses  intellectual
property.  The Company enters into confidentiality agreements with its employees
and   limits    distribution    of   proprietary    information.    There    can
 
                                       29
<PAGE>
be  no assurance  that the  steps taken by  the Company  in this  regard will be
adequate to  deter  misappropriation  of proprietary  information  or  that  the
Company  will be able to  detect unauthorized use and  take appropriate steps to
enforce its  intellectual property  rights. See  "Risk Factors  --  Intellectual
Property Rights."
 
    Software  developed by Whittman-Hart in  connection with a client engagement
is typically assigned  to the  client. In  limited situations,  the Company  may
retain   ownership,  or  obtain  a  license   from  its  client,  which  permits
Whittman-Hart or a third party to market  the software for the joint benefit  of
the client and Whittman-Hart or for the sole benefit of Whittman-Hart.

Work-Registered Trademark-" and "We Are It-Registered Trademark-" are registered
service marks  of Whittman-Hart.  The  Company holds  no patents  or  registered
copyrights,  and  has no  present intention  of making  any copyright  or patent
applications.
    
 
PROPERTY
 
   
    Whittman-Hart's principal executive offices are located at 311 South  Wacker
Drive,   Chicago,  Illinois.  The  Company's  lease  on  these  premises  covers
approximately 50,000 square feet and expires October 31, 2004. The Company  also
leases  facilities in  Indianapolis, Milwaukee, Denver,  Cincinnati, Peoria, Ft.
Wayne and Dallas.  See Note 5  of Notes to  Financial Statements.  Whittman-Hart
anticipates  that additional space will be  required as its business expands and
believes that it will be able to obtain suitable space as needed.
    
 
LEGAL PROCEEDINGS
 
    Whittman-Hart is not involved in any material legal proceedings.

(1)  All options were granted on December 31,  1995. The ISOs vest in thirds  on
     the first three anniversaries of the stock option grant. The NQSOs vest 10%
     upon  grant and 22.5% on each of  the first four anniversaries of the stock
     option grant, respectively,  except that options  to purchase 8,000  shares
     granted to Mr. Gaskey vested immediately upon grant.
 
(2)  Based  on an aggregate of  910,856 options granted in  1995 to employees of
     the Company, including the Named Executive Officers.
 
(3)  The exercise  price  equals  the  fair market  value  of  Common  Stock  as
     determined  by the Board  of Directors on  that date, based  on a valuation
     prepared by Broadview Associates. The exercise price is payable in cash or,
     subject to certain limitations, by delivery of shares of Common Stock.
 
(4)  The potential  realizable value  is calculated  based on  the term  of  the
     option at the time of grant (ten years). Stock price appreciation of 5% and
     10%  is based on the fair  value at the time of  grant and assumes that the
     option is exercised at the exercise price  and sold on the last day of  its
     term  at  the  appreciated  price, pursuant  to  rules  promulgated  by the
     Securities and Exchange Commission. The potential realizable value does not
     represent the Company's  prediction of  its stock  price performance.  This
     table  does not take  into account appreciation  for the fair  value of the
     Common Stock from the date of grant to date. There can be no assurance that
     the actual stock price appreciation over the ten-year option will be at the
     assumed 5% and 10% levels or at any other defined level. If for purposes of
     this calculation the fair market value of  the Common Stock on the date  of
     grant  was assumed to have equaled the price to the public in the Company's
     initial public  offering, the  potential realizable  value of  the  options
     calculated would substantially exceed the potential realizable values shown
     in the table.
 
    The following table sets forth certain information with respect to the value
of  options held at December  31, 1995 by the  Named Executive Officers who held
options during 1995. The Named Executive  Officers did not exercise any  options
to purchase Common Stock during 1995.

(1)  Until  May 3, 1996, the Common Stock  was not publicly traded. The Board of
     Directors, in connection with  grants of stock options  from time to  time,
     determines  the fair market value of the Common Stock as of the grant date.

EMPLOYMENT AGREEMENTS
 
    The Company is a party to substantially identical employment contracts  with
Messrs. Bernard, Szofer, Gaskey and Metelmann and Ms. Reardon, pursuant to which
each  of those individuals serves as an executive of the Company at compensation
levels and terms to  be agreed upon between  those individuals and the  Company.
These  agreements provide  that upon termination  of employment  by the Company,
other than for Cause (as defined  in the agreements) or retirement, the  Company
shall  pay the  officer an  amount equal  to twice  the executive's  annual base
compensation in effect at the time of termination in the case of Messrs. Bernard
and Szofer and  one year in  the case of  Messrs. Gaskey and  Metelmann and  Ms.
Reardon.  The agreements also provide  that in the event  of a Change in Control
(as defined in the agreements) and the occurrence of certain events, and to  the
extent  deductible under  then applicable tax  laws, the Company  shall pay such
executives a payment equal  to two times  the sum of:  (i) the executives'  most
recent  base annual compensation in effect at the date of the Change in Control;
and (ii)  the  cash  value  of  purchasing  on  an  individual  basis  insurance
protection  (including dependent coverage) that is equal to the coverage then in
effect with respect to the Company's health insurance plan, based upon the  cost
of  such  insurance coverage  for  a six-month  period  following the  Change in
Control date. Mr. Bernard's employment  agreement does not provide for  payments
in  the event  of a Change  in Control. Each  of these executives  is subject to
noncompetition, nonsolicitation and nondisclosure covenants.
 
STOCK PLANS
 
    EMPLOYEE STOCK PURCHASE  PLAN.   The Company  has reserved  an aggregate  of
400,000  shares of Common Stock for  issuance under the Company's Employee Stock
Purchase Plan (the "Purchase Plan"). Such shares may be authorized but  unissued
Common  Stock, treasury shares or Common Stock purchased in the open market. The
Purchase Plan is intended to qualify  under Section 423 of the Internal  Revenue
Code of 1986, as amended (the "Code"), and will permit eligible employees of the
Company  who have  completed five  full calendar  months of  service to purchase
Common Stock  through  payroll deductions  of  up to  20%  of their  total  cash
compensation,  provided that no employee may purchase more than $20,000 worth of
stock in  any  calendar year.  The  Purchase  Plan has  two  six-month  offering
periods,  beginning on  April 1  and September  1 of  each year,  with the first
offering period commencing on May 3, 1996. The Purchase Price (as defined in the
Purchase Plan) of Common Stock purchased  under the Purchase Plan equals 90%  of
the market value of the Common Stock (as calculated in the Purchase Plan) on the
first  or last day of an offering  period, whichever is lower. The Purchase Plan
is administered by  the Compensation Committee.  The Board is  able to amend  or
terminate  the Purchase Plan  at any time.  However, the Board  may not, without
stockholder approval, modify the  Purchase Plan if  stockholder approval of  the
amendment  is required  for the  Purchase Plan  to continue  to comply  with the
requirements of Rule 16b-3 under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), and Section 423 of the Code.
 
   
    ESOP.  The Company sponsors an  Employee Stock Ownership Plan (the  "ESOP"),
covering  substantially all employees of the Company. As of August 20, 1996, the
ESOP owned 236,916 shares of Common Stock.  The Company does not intend to  make
future contributions to the ESOP. See Note 8 of Notes to Financial Statements.
    
 
    1995  INCENTIVE  STOCK  PLAN.   The  Company  has reserved  an  aggregate of
2,000,000 shares of  Common Stock for  issuance under the  1995 Incentive  Stock
Plan, as amended (the "Incentive Stock Plan"), which may be granted to employees
and officers of the Company. The maximum number of shares that may be subject to
awards  granted to  any participant  in any  fiscal year  is 88,084  shares. The
Incentive  Stock  Plan  is  administered  by  the  Compensation  Committee.  The
Incentive  Stock Plan  provides for awards,  which may consist  of Common Stock,
restricted shares of Common Stock, NQSOs  and ISOs to purchase shares of  Common
Stock, performance awards and stock appreciation rights ("SARs").
 
    The  exercise  price  for  options  may  be  paid:  (i)  in  cash;  (ii)  by
surrendering shares already owned by the optionee; or (iii) if the  Compensation
Committee so determines by instructing a broker to sell enough of the optionee's
exercised  shares to deliver to the Company sufficient sales proceeds to pay the
exercise price. The exercise  price per share  of Common Stock  may not be  less
than  85% (100% in  the case of  an ISO) of  the mean of  the highest and lowest
sales  price  for  the  Common  Stock  last  reported  on  the  Nasdaq  National
 
                                       35
<PAGE>
Market  on the date the stock  option is granted. The base  value of an SAR will
equal not less than 85% of  the market value of a  share of Common Stock on  the
grant  date. Options and SARs to be  granted under the Incentive Stock Plan must
be exercised within fifteen years from the date of grant (ten years in the  case
of  ISOs) and will  generally vest in  annual installments as  determined by the
Compensation Committee. In  the case  of any eligible  employee who  owns or  is
deemed  to own stock possessing more than 10% of the total combined voting power
of all classes of stock of the  Company, the exercise price of any ISOs  granted
under  the Incentive  Stock Plan may  not be less  than 110% of  the fair market
value of the Common Stock on the date  of grant and the exercise period may  not
exceed five years from the date of grant.
 
    The  Board of Directors can  terminate or amend the  Incentive Stock Plan at
any time, except that no such action generally will be able to adversely  affect
any right or obligation regarding any awards previously made under the Incentive
Stock  Plan without the consent of the  recipient. In addition, no amendment may
be effective without  the prior approval  of stockholders, if  such approval  is
required  for the  Incentive Stock  Plan to  continue to  comply with applicable
regulations of the Securities and Exchange Commission (the "Commission"). In the
event of any changes in  the capital structure of the  Company, such as a  stock
dividend  or split-up, the Board of Directors must make equitable adjustments to
outstanding unexercised awards and to the provisions of the Incentive Stock Plan
so that the  net value of  the award is  not changed. If  the Company becomes  a
party to a merger, reorganization, liquidation or similar transaction, the Board
of Directors may make such arrangements it deems advisable regarding outstanding
awards,  such  as  substituting  new  awards  for  outstanding  awards, assuming
outstanding awards or terminating or paying for outstanding awards.
 
   
    At August 20, 1996, ISOs for 50,908 shares and NQSOs for 814,330 shares were
outstanding under the Incentive Stock Plan.

                              CERTAIN TRANSACTIONS
 
    In August 1995, Frontenac purchased 173,832 preferred equity units in LP for
$4.0 million and Platinum purchased 65,187 preferred equity units in LP for $1.5
million.  The preferred equity units were converted into a like number of shares
of Redeemable Preferred Stock  in connection with  the Reorganization, and  such
shares  were converted into 956,074 shares  of Common Stock immediately prior to
the consummation of the  Company's initial public  offering. See "The  Company."
Contemporaneously with Frontenac's and Platinum's investment in preferred equity
units,  the Company redeemed 260,748 common equity units owned by Mr. Bernard at
a redemption price of $5.75 per unit, or a total of $1.5 million.
 
    Frontenac and Platinum were granted certain registration rights with respect
to the preferred equity units and any securities issuable upon conversion of the
preferred equity units. They were also granted certain other rights,  including:
(i) the right to each designate one member to the Company's five person Board of
Directors;  (ii)  certain class  voting rights;  (iii) certain  preferences upon
liquidation, dissolution or winding up of the Company; (iv) a preferred dividend
accrual of 10% per annum payable upon redemption of the preferred equity  units;
and  (v) certain rights  of first refusal and  co-sale rights involving existing
management securities. In  addition, Frontenac,  Platinum, Limited  and each  of
Messrs.  Bernard and Szofer entered into a Voting Agreement whereby the parties,
other than Limited, agreed to vote in favor of the others' respective  designees
to  the Board of Directors. The  preferential rights, including those enumerated
above,  and  the   Voting  Agreement,  terminated   immediately  prior  to   the
consummation of the Company's initial public offering.
 
    During  the time when the Company's business was conducted as a partnership,
various loans were made  among Mr. Bernard,  Limited and LP,  all of which  have
been  repaid.  As of  December 31,  1995, loans  by the  Company to  Mr. Bernard
aggregated $326,356 and bore interest  at the per annum  rate of prime less  2%.
These loans were made to enable Mr. Bernard to make certain payments owed by him
to  an affiliate of  the Company. Also as  of December 31,  1995, loans from Mr.
Bernard to the Company  aggregated $317,413 and bore  interest at the per  annum
rate  of  10%. These  loans  were made  for  working capital  and  other general
corporate purposes.  Subsequent to  December  31, 1995,  the loans  were  offset
against  each other and the remaining balance owed by Mr. Bernard to the Company
was paid in full.
 
    In 1995  the Company  acquired  a 50%  ownership  interest in  Sleep  Relief
L.L.C.,  an Illinois  limited liability  company ("Sleep  Relief"). Sleep Relief
develops and markets sleep laboratory software products and provides consulting,
education and risk assessment services to providers involved in the practice  of
sleep  medicine as well as organizations  seeking to identify sleep disorders in
targeted populations.  Recently, Sleep  Relief entered  into an  agreement  with
HealthDyne  Technologies,  Inc. to  distribute  Sleep Relief's  sleep management
software and related documents. In consideration of its ownership interest,  the
Company  made  a nominal  capital investment  in Sleep  Relief and  committed to
provide up to  $150,000 in  technical and  administrative support  and to  match
capital  contributions made by  other interested parties,  provided an appraisal
determines that the  value of Sleep  Relief will  increase by the  value of  the
Company's   contribution.  Mr.  Bernard  serves  on  Sleep  Relief's  Management
Committee.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
   
    The Company's  authorized capital  stock consists  of 15,000,000  shares  of
Common  Stock,  par value  $.001 per  share, and  3,000,000 shares  of preferred
stock, $.001 par value per share, to be issued from time to time by the Board of
Directors as shares of one or more classes or series ("Blank Check  Preferred").
The  Company currently has outstanding 8,953,752  shares of Common Stock, and no
shares of Blank Check Preferred. Upon  completion of this offering, the  Company
will  have outstanding 10,003,752 shares of Common  Stock and no shares of Blank
Check Preferred. As  of August  20, 1996,  there were  43 holders  of record  of
Common Stock.
    
 
COMMON STOCK
 
    The  holders of Common Stock are entitled to  one vote for each share on all
matters voted upon by stockholders, including the election of directors.
 
    Subject to the rights of any then-outstanding shares of preferred stock, the
holders of the Common Stock are entitled to such dividends as may be declared at
the discretion  of  the  Board  of Directors  out  of  funds  legally  available
therefor.  See "Dividend Policy." Holders of  Common Stock are entitled to share
ratably in  the net  assets of  the Company  upon liquidation  after payment  or
provision  for all  liabilities and any  preferential liquidation  rights of any
preferred stock then outstanding. The holders of Common Stock have no preemptive
rights to purchase  shares of  capital stock of  the Company.  Shares of  Common
Stock  are not subject to any redemption provisions and are not convertible into
any other securities of the Company. All outstanding shares of Common Stock are,
and the shares of Common Stock to  be issued pursuant to this offering will  be,
upon   payment  therefor,  duly  authorized,  validly  issued,  fully  paid  and
non-assessable.
 
    The Common Stock is  listed on the Nasdaq  National Market under the  symbol
"WHIT."
 
PREFERRED STOCK
 
    Subject  to the provisions of the Company's Certificate of Incorporation and
limitations prescribed by law, the Board of Directors is expressly authorized to
adopt resolutions to issue shares of Blank Check Preferred, to fix the number of
such shares and to change the number of such shares constituting any series, and
to provide  for  or change  the  voting powers,  designations,  preferences  and
relative,  participating,  optional  or  other  special  rights, qualifications,
limitations  or  restrictions  thereof,  including  dividend  rights  (including
whether   dividends  are  cumulative),  dividend   rates,  terms  of  redemption
(including sinking fund  provisions), redemption prices,  conversion rights  and
liquidation  preferences of the shares constituting any class or series of Blank
Check Preferred,  in  each  case without  any  further  action or  vote  by  the
stockholders.  The Company  has no  current plans to  issue any  shares of Blank
Check Preferred.
 
DELAWARE LAW AND CERTAIN CERTIFICATE OF INCORPORATION AND BY-LAW PROVISIONS;
ANTI-TAKEOVER EFFECTS
 
    The Company is  subject to  the provisions of  Section 203  of the  Delaware
General Corporation Law (the "DGCL"). Subject to certain exceptions, Section 203
prohibits  a publicly  held Delaware  corporation from  engaging in  a "business
combination" with an "interested stockholder" for a period of three years  after
the   date  of  the  transaction  in  which  the  person  became  an  interested
stockholder, unless the  interested stockholder  attained such  status with  the
approval  of the Board of Directors or the business combination is approved in a
prescribed manner,  or  certain  other conditions  are  satisfied.  A  "business
combination"  includes a merger, asset sale  or other transaction resulting in a
financial benefit to the interested stockholder. Subject to certain  exceptions,
an  "interested  stockholder"  is a  person  who, together  with  affiliates and
associates,  owns,  or  within  three  years  did  own,  15%  or  more  of   the
corporation's voting stock.
 
    The  Company's  Certificate of  Incorporation and  By-Laws provide  that the
directors of the Company shall be classified into three classes, with  staggered
three-year  terms.  See "Management  -- Directors  and Executive  Officers." Any
director may be removed only for cause upon the affirmative vote of at least 66%
of the shares entitled to vote for the election of directors.
 
    The Company's  By-Laws  provide  that  for  nominations  for  the  Board  of
Directors or for other business to be properly brought by a stockholder before a
meeting  of stockholders,  the stockholder must  first have  given timely notice
thereof in writing to the Secretary of the Company. To be timely, a notice  must
generally  be delivered not less than 60 days nor more than 90 days prior to the
first anniversary of the preceding year's
 
                                       39
<PAGE>
annual meeting. The notice must contain, among other things, certain information
about the  stockholder  delivering the  notice  and, as  applicable,  background
information  about each nominee or a description  of the proposed business to be
brought before the meeting.
 
    The Company's By-Laws provide that  special meetings of stockholders may  be
called  only by the Chairman  of the Board of Directors  or the President of the
Company. These  provisions could  have the  effect of  delaying until  the  next
annual stockholders meeting stockholder actions which are favored by the holders
of a majority of the outstanding voting securities of the Company.
 
    The  foregoing provisions could have the  effect of making it more difficult
for a third party to acquire, or  of discouraging a third party from  acquiring,
control of the Company.
 
    The  existence of  Blank Check Preferred  enables the Board  of Directors to
render more  difficult or  to discourage  an attempt  to obtain  control of  the
Company  by means of a tender offer, proxy contest, merger or otherwise, thereby
protecting the continuity  of the  Company's management. The  issuance of  Blank
Check  Preferred pursuant to  the Board of  Directors' authority described above
may adversely affect  the rights of  the holders of  Common Stock. For  example,
Blank  Check Preferred issued by the Company  may rank prior to the Common Stock
as to dividend rights, liquidation preference or both, may have full or  limited
voting  rights and may be convertible  into shares of Common Stock. Accordingly,
the issuance of Blank Check Preferred  may discourage bids for the Common  Stock
or may otherwise adversely affect the market price of the Common Stock.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION
 
    The  Company's  Certificate  of  Incorporation  contains  certain provisions
permitted  under  the  DGCL  relating  to  the  liability  of  directors.  These
provisions  eliminate  a  director's  personal  liability  for  monetary damages
resulting from  a breach  of  fiduciary duty,  except in  certain  circumstances
involving  certain wrongful acts, such as: (i)  for any breach of the director's
duty of loyalty to the Company or  its stockholders; (ii) for acts or  omissions
not in good faith or which involve intentional misconduct or a knowing violation
of  law; (iii) under Section  174 of the DGCL; or  (iv) for any transaction from
which the director derives an improper personal benefit. These provisions do not
limit or  eliminate  the  rights of  the  Company  or any  stockholder  to  seek
non-monetary  relief, such  as an  injunction or rescission,  in the  event of a
breach of  a  director's fiduciary  duty.  These  provisions will  not  alter  a
director's liability under federal securities laws. The Company's Certificate of
Incorporation and By-Laws also contain provisions indemnifying the directors and
officers of the Company to the fullest extent permitted by the DGCL. The Company
believes  that  these  provisions  will assist  the  Company  in  attracting and
retaining qualified individuals to serve as directors and officers.
 
REGISTRATION RIGHTS
 
   
    Under the terms of  a Registration Agreement dated  as of December 31,  1995
(the  "1995 Registration  Agreement"), among  Frontenac, Platinum (collectively,
the "1995  Investors") and  the Company,  at any  time after  May 8,  1996  (the
closing  date  of  the Company's  initial  public  offering), the  holders  of a
majority of  the Registrable  Stock  (as defined  therein),  have the  right  to
require  the Company to register any or all of the Registrable Stock, subject to
the conditions and limitations contained in the 1995 Registration Agreement.  In
addition,  under the terms  of a Registration  Agreement dated May  8, 1996 (the
"1996 Registration Agreement" and together with the 1995 Registration Agreement,
the "Registration Agreements"), among  the Company, Mr.  Bernard and Mr.  Szofer
(Mr. Bernard and Mr. Szofer, together with the 1995 Investors, the "Investors"),
at  any time after May 8, 1997, Mr.  Szofer has the right to require the Company
to register 50,000 of his shares of Common Stock, subject to the conditions  and
limitations contained in the 1996 Registration Agreement.
    
 
    In  addition, pursuant to the Registration Agreements and the conditions and
limitations set  forth  therein,  the  Company  is  required  to:  (i)  pay  all
associated Registration Expenses (as defined therein) in connection with certain
registrations; (ii) use its best efforts to effect such registrations; and (iii)
indemnify  the  Investors  and  certain  of  their  affiliates  against  certain
liabilities, including liabilities under the Securities Act, in connection  with
the registration of their shares.
 
TRANSFER AGENT AND REGISTRAR
 
    The  transfer agent and registrar  for the Common Stock  is Harris Trust and
Savings Bank.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
    Upon completion of this offering, the Company will have 10,003,752 shares of
Common  Stock outstanding.  Of these shares,  the 2,000,000 shares  sold in this
offering and  the  3,105,000  shares  issued in  the  Company's  initial  public
offering  will be freely  tradeable without restriction  or further registration
under the Securities Act,  except that any shares  purchased by "affiliates"  of
the  Company, as that  term is defined under  the Securities Act ("Affiliates"),
may generally  only be  sold in  compliance  with the  limitations of  Rule  144
described below.
    
 
   
    All  of  the  remaining shares  of  Common Stock  (the  "Restricted Shares")
constitute restricted securities under Rule  144. Of these "Restricted  Shares,"
approximately  4,880,626 will be subject to a lock-up period expiring on October
30, 1996 (the "Lock-Up  Period"). Following the Lock-Up  Period, 583,958 of  the
Restricted  Shares will immediately become  eligible for sale, subject, however,
in the case of 274,009 shares, to the volume limitations and restrictions (other
than the  holding  period requirement)  of  Rule 144.  The  remaining  4,296,668
Restricted  Shares will become eligible for sale under Rule 144 at various times
between December 1996 and December 1997. See "Underwriting."
    
 
    In general, under Rule 144 of the  Securities Act as currently in effect,  a
person  (or  persons whose  shares are  aggregated)  who has  beneficially owned
Restricted Shares for at least two years,  including a person who may be  deemed
an Affiliate of the Company, is entitled to sell within any three-month period a
number  of shares of Common Stock that does  not exceed the greater of 1% of the
then outstanding shares of Common Stock or the average weekly trading volume  of
the  Common Stock  as reported  on the  Nasdaq National  Market during  the four
calendar weeks preceding such sale. Sales under Rule 144 are subject to  certain
restrictions  relating to manner of sale, notice and the availability of current
public information about the Company. In  addition, under Rule 144(k), a  person
who is not an Affiliate of the Company at any time 90 days preceding a sale, and
who has beneficially owned shares for at least three years, would be entitled to
sell  such  shares without  regard  to the  volume  limitations, manner  of sale
provisions or  notice or  other requirements  of Rule  144. The  Commission  has
proposed  to amend the  holding period required  by Rule 144  to permit sales of
"restricted" securities after  one year  rather than  two years  (and two  years
rather than three years for "non-affiliates" under Rule 144(k)).
 
   
    At  August 20, 1996, options to purchase a total of 907,238 shares of Common
Stock were outstanding, (all  of which options, other  than options to  purchase
42,000 shares, were granted under the Incentive Stock Plan), of which options to
purchase  98,456 shares were then exercisable. An additional 1,132,522 shares of
Common Stock were available for future  option grants or direct issuances  under
the  Incentive Stock Plan, and 400,000 shares of Common Stock were available for
direct issuances under the Purchase Plan.  See "Management -- Stock Plans."  All
2,000,000  shares issuable  upon exercise  of options  granted or  to be granted
under the Incentive Stock  Plan and 400,000 shares  issuable under the  Purchase
Plan  are registered on a Form S-8. When issued by the Company, such shares will
be freely tradeable, except that, if held  by an Affiliate, such shares will  be
subject  to  the volume  limitations and  restrictions  (other than  the holding
period requirement) of Rule 144.
    
 
   
    The Company has granted Frontenac and Platinum and their transferees  demand
and piggyback registration rights covering an aggregate of 404,574 shares. These
registration  rights  will become  exercisable after  expiration of  the Lock-Up
Period. Mr. Szofer also  has demand and  piggyback registration rights  covering
50,000  shares. The demand registration rights  are not exercisable until May 8,
1997. When and  as these  rights are  exercised, additional  shares will  become
available  for sale  upon the  effectiveness of  a registration  statement filed
pursuant to  exercise of  such  rights. See  "Description  of Capital  Stock  --
Registration Rights."

</TABLE>
    
 
    The Underwriting  Agreement provides  that the  obligations of  the  several
Underwriters  to purchase the  Shares offered hereby are  subject to approval of
certain legal matters by their counsel  and to certain other conditions. If  any
of  the Shares  are purchased by  the Underwriters pursuant  to the Underwriting
Agreement, the Underwriters are obligated to  purchase all of the Shares  (other
than those covered by the over-allotment option described below).
 
   
    The   Company  and  the  Selling  Stockholders  have  been  advised  by  the
Underwriters that they propose  to offer the Shares  to the public initially  at
the  price to the public set  forth on the cover page  of this Prospectus and to
certain dealers at  such price, less  a concession  not in excess  of $0.94  per
Share.  The Underwriters may allow, and  such dealers may re-allow, a concession
not in excess of $0.10 per Share to certain other dealers. After this  offering,
the offering price and other selling terms may be changed by the Underwriters.
    
 
   
    Pursuant  to the  Underwriting Agreement, certain  Selling Stockholders have
granted to the Underwriters  an option, exercisable not  later than 30  calendar
days  from the  date of  the Underwriting Agreement,  to purchase  up to 300,000
additional Shares at  the offering price  set forth  on the cover  page of  this
Prospectus,  less the  underwriting discounts  and commissions,  solely to cover
over-allotments.
    
 
   
    To the  extent that  the  Underwriters exercise  such  option, each  of  the
Underwriters  will have  a firm  commitment to  purchase approximately  the same
percentage of the option shares  as the number of Shares  to be purchased by  it
shown  in the above table bears to the total number of Shares shown in the above
table, such Selling Stockholders will be  obligated, pursuant to the option,  to
sell  such Shares to the Underwriters. The Underwriters may exercise such option
only to cover  over-allotments made in  connection with the  sale of the  Shares
offered hereby. If purchased, the Underwriters will sell such additional 300,000
Shares on the same terms as those on which the Shares are being offered.
    
 
    The  Underwriting  Agreement  contains  covenants  of  indemnity  among  the
Underwriters, the Company  and the  Selling Stockholders  against certain  civil
liabilities, including liabilities under the Securities Act.
 
    The  Company, the Selling Stockholders, the executive officers and directors
of the Company and certain employees of the Company have each agreed that during
the Lock-Up  Period  they  will  not,  without  the  prior  written  consent  of
Donaldson,  Lufkin  &  Jenrette  Securities Corporation,  sell,  offer  to sell,
contract to  sell, grant  any option  to purchase  or otherwise  dispose of  any
shares  of Common  Stock or  any securities  convertible into  or exercisable or
exchangeable for Common Stock,  other than the Shares,  except that the  Company
may  issue shares  upon the exercise  of stock  options granted prior  to May 2,
1996, and may grant additional options under its stock option and other employee
compensation  plans,  provided  that,  without  the  prior  written  consent  of
Donaldson,  Lufkin & Jenrette Securities Corporation,  such options shall not be
exercisable during the Lock-Up Period.
 
    In connection  with the  offering, certain  Underwriters and  selling  group
members  may engage in passive market making transactions in the Common Stock on
the Nasdaq National Market  immediately prior to the  commencement of sales,  in
accordance  with  Rule  10b-6A under  the  Exchange Act.  Passive  market making
consists of, among other things, displaying  bids on the Nasdaq National  Market
limited by the bid prices of
 
                                       42
<PAGE>
independent  market makers and purchases limited  by such prices and effected in
response to order flow. Net purchases by a passive market maker on each day  are
limited  to a specified  percentage of the passive  market maker's average daily
trading volume in  the Common  Stock during a  specified prior  period, and  all
passive  market making activity must be discontinued when such limit is reached.
Passive market making may stabilize  the market price of  the Common Stock at  a
level  above  that  which might  otherwise  prevail  and, if  commenced,  may be
discontinued at any time.
 
                                 LEGAL MATTERS
 
    The legality of  the issuance of  the shares offered  hereby will be  passed
upon  for the  Company by  Sachnoff &  Weaver, Ltd.,  Chicago, Illinois. Certain
legal matters will be passed upon for the Underwriters by Katten Muchin & Zavis,
Chicago, Illinois.

    The Company has filed  with the Commission  Registration Statements on  Form

                          INDEPENDENT AUDITORS' REPORT
 
The Stockholders and Board of Directors
Whittman-Hart, Inc.:
 
    We have audited the accompanying balance sheets of Whittman-Hart, Inc. as of
December   31,  1994  and   1995,  and  the   related  statements  of  earnings,
stockholders' equity, and  cash flows for  each of the  years in the  three-year
period   ended   December  31,   1995.  These   financial  statements   are  the
responsibility of the Company's management. Our responsibility is to express  an
opinion on these financial statements based on our audits.
 
    We  conducted  our audits  in  accordance with  generally  accepted auditing
standards. Those standards require that we plan and perform the audit to  obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also  includes
assessing  the  accounting principles  used  and significant  estimates  made by
management, as well as evaluating the overall financial statement  presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In  our opinion, the financial statements  referred to above present fairly,
in all material respects,  the financial position of  Whittman-Hart, Inc. as  of
December 31, 1994 and 1995, and the results of its operations and its cash flows
for  each  of the  years in  the three-year  period ended  December 31,  1995 in
conformity with generally accepted accounting principles.

accompanying  financial   statements.   Partnership   income   before   business
combination  as reported  in the  statements of  stockholders' equity represents
LP's undistributed earnings.
 
    Effective December  31,  1995,  the Company  issued  common  and  redeemable
convertible  preferred stock in exchange for the remaining partnership interests
of LP. The exchange  represents a combination of  entities under common  control
and  has been accounted  for on an "as-if"  pooling-of-interests basis, with the
accompanying financial statements restated for all periods presented.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  USE OF ESTIMATES
 
    The  preparation  of  financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions that  affect the  reported  amounts of  assets and  liabilities  and
disclosure  of contingent  assets and liabilities  at the date  of the financial
statements and  the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.
 
  REVENUE RECOGNITION
 
    Revenues are recognized as the related services are performed.
 
  PROPERTY AND EQUIPMENT
 
    Depreciation  is  computed  using  the  straight-line  method  based  on the
estimated useful lives, ranging from two to seven years, of the various  classes
of property. Amortization of leasehold improvements is computed over the shorter
of the lease term or estimated useful life of the asset.
 
  CASH EQUIVALENTS
 
    Cash  equivalents consist of Eurodollar time  deposits which mature in seven
days.
 
  INCOME TAXES
 
    Income taxes,  including  pro  forma  calculations,  are  accounted  for  in
accordance with Statement of Financial Accounting Standards No. 109, "Accounting
for  Income Taxes"  ("Statement 109"). Under  the asset and  liability method of
Statement 109, deferred tax assets and liabilities are recognized for the future
tax consequences  attributable to  differences between  the financial  statement
carrying  amounts of  existing assets and  liabilities and  their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax  rates
expected  to  apply to  taxable income  in  the years  in which  those temporary
differences are expected to be recovered or settled. The effect on deferred  tax
assets  and liabilities of a change in tax  rates is recognized in income in the
period that includes the enactment date.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
  PRO FORMA NET INCOME PER SHARE
 
    Pro forma net  income per  common and  common equivalent  share is  computed
based  on the weighted average of  7,064,886 common and common equivalent shares
(redeemable convertible  preferred  stock,  10%, $.001  par  value  ("Redeemable
Preferred Stock") and stock options) outstanding during the year.
 
    Pursuant to Securities and Exchange Commission Staff Accounting Bulletin No.
83,  common  and  common  equivalent  shares  issued  during  the  twelve months
immediately preceding the initial public offering date (using the treasury stock
method and the initial  public offering price per  share) have been included  in
the  calculation  of  common  and  common  equivalent  shares  as  if  they were
outstanding for the entire period presented.
 
  RECLASSIFICATIONS
 
    Certain 1993 and 1994 balances have been reclassified to conform to the 1995
presentation.
 
3.  REDEEMABLE CONVERTIBLE PREFERRED STOCK
    During 1995, the Company issued 239,019 shares of Redeemable Preferred Stock
which have a preference  value equal to  $23.01 per share  plus all accrued  but
unpaid  dividends. Dividends  of $183,334 were  accreted in 1995.  Each share of
Redeemable Preferred  Stock is  convertible  into four  shares of  common  stock
subject  to  adjustments  for  anti-dilution.  The  holders  of  the  Redeemable
Preferred Stock are entitled  to one vote  for each share  of common stock  into
which  such holders' Redeemable Preferred Stock may be converted. The Redeemable
Preferred Stock was recorded at  fair value on the  date of issuance less  issue
costs.  The excess  of the  preference value  over the  carrying value  is being
accreted by periodic charges to additional paid-in capital over the life of  the
issue. Accretion of issue costs were $7,236 in 1995.
 
    Each  holder  of the  Redeemable Preferred  Stock may  elect to  require the
Company to redeem  such holder's  Redeemable Preferred Stock  at its  preference
value  at any  time after  certain events  have occurred  or July  31, 2000. All
Redeemable  Preferred  Stock  shall   automatically  convert  to  common   stock
immediately  prior  to the  closing  of a  sale of  common  stock pursuant  to a
registration  statement  declared  effective  by  the  Securities  and  Exchange
Commission  if  the aggregate  sales proceeds  exceed  certain levels.  Upon the
conversion of any Redeemable Preferred Stock into common stock, any accrued  and
unpaid dividends shall be canceled.
 
4.  DEBT OBLIGATIONS
 
  LINE OF CREDIT
 
    The  Company has a line of credit with a bank which expires on July 31, 1996
and provides a maximum borrowing of $2,000,000. Borrowings are limited to 80% of
eligible accounts receivable and bear interest  at the bank's prime rate or  the
London  Interbank Offered Rate (LIBOR) plus 1.5%. No borrowings were outstanding

6.  INCOME TAXES
    The  Company's business was previously owned  and operated by LP; therefore,
federal income tax liabilities were  the responsibility of the partners.  Income
taxes  are comprised of certain  state income taxes of  LP and federal and state
income taxes of the  Company. The pro forma  income tax adjustments included  in
the statements of earnings represent federal and the additional state income tax
expense  that  would  have  been  required  had  the  Company  operated  as  a C
corporation for all periods presented.
 
    The tax effects  of temporary  differences that  give rise  to deferred  tax
assets and liabilities at December 31, 1995 are as follows:

7.  EXECUTIVE STOCK PLAN
    The  Company's Executive Stock Plan (the  "Plan") is used to reward selected
executives for future services.  Under the Plan,  executives are awarded  common
stock  that vests over a specified period. In the event employment is terminated
prior to  vesting, the  executive will  not be  entitled to  receive the  common
stock.  Executive stock expense reported in  the statements of earnings amounted
to $116,701, $29,168 and $241,668 in 1993, 1994 and 1995, respectively.
 
8.  EMPLOYEE STOCK OWNERSHIP PLAN
    The Company sponsors an Employee Stock Ownership Plan ("ESOP") which  covers

service. Annual  ESOP contributions  are  determined at  the discretion  of  the
Company's  Board  of  Directors.  Plan participants  become  fully  vested after
completing four years of service. ESOP contributions reported in the  statements
of  earnings amounted to  $175,000 and $137,411 in  1993 and 1994, respectively.

contributions amounted to $87,337, $92,100 and $183,857 in 1993, 1994 and  1995,
respectively.
 
10. STOCK OPTIONS
    In  1995,  the  Company adopted  a  stock  option plan  under  which certain
employees may be granted  the right to  purchase shares of  common stock at  the
fair  market value on the date of grant.  Stock options may be exercised only to
the extent they  have vested  in accordance  with provisions  determined by  the
Board of Directors.
 
    During  1995,  stock options  were granted  to  purchase 880,856  and 30,000
shares of the  Company's common  stock at exercise  prices of  $6.49 and  $3.29,
respectively.  At December 31, 1995, all of the options granted were outstanding
and options  to  purchase 90,080  shares  of  the Company's  common  stock  were
exercisable.
 
11. RELATED-PARTY TRANSACTIONS
    Notes receivable from a stockholder bear interest at 2% below the prime rate
and  are  due on  demand. Additionally,  notes  receivable from  executives bear
interest at the prime rate and are due on various dates through August 1998.
 
    Unsecured notes payable to a stockholder bear interest at 10% and are due on
December 31, 1996.
 
12. REVENUES FROM SIGNIFICANT CLIENTS
    In 1993  and  1995,  one  client accounted  for  approximately  10%  of  the
Company's total revenues.
 
13. SUBSEQUENT EVENTS
    During  February 1996, the notes receivable -- stockholder and notes payable
- -- stockholder (note 11) were repaid.
 
    The Company's Board of Directors approved a 4 for 1 split of common stock in
the form of a stock dividend effective  April 3, 1996. All common share and  per
share  amounts  have been  adjusted retroactively  to give  effect to  the stock
split. Additionally, on  April 3, 1996,  the Company filed  an Amendment to  its
Certificate  of Incorporation effecting an increase  in the number of authorized
shares of  common  stock  to  15,000,000 and  authorizing  3,000,000  shares  of
preferred  stock. The  authorized numbers of  shares have been  adjusted to give
effect to these increases.
 
    In connection with the Company's initial public offering, 239,019 shares  of
Redeemable  Preferred  Stock will  be converted  into  956,074 shares  of common
stock.
 
    A portion of the proceeds of  the Company's initial public offering will  be
used to retire two promissory notes totaling $1,666,500.

                    NOTES TO UNAUDITED FINANCIAL STATEMENTS
 
   
                             JUNE 30, 1995 AND 1996
    
 
1.  BASIS OF PRESENTATION
    The  accompanying unaudited  interim financial  statements of Whittman-Hart,
Inc. (the "Company") have been prepared pursuant to the rules and regulations of
the Securities and Exchange  Commission and should be  read in conjunction  with
the Company's audited financial statements and notes thereto set forth elsewhere
herein.  The information furnished herein includes all adjustments which are, in
the opinion of  management, necessary  for a  fair presentation  of results  for
these  interim  periods, and  all  such adjustments  are  of a  normal recurring
nature.
 
    The results of operations  for the six  months ended June  30, 1996 are  not
necessarily  indicative  of  the results  to  be  expected for  the  year ending
December 31, 1996.
 
2.  CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS
    Cash equivalents are  comprised of  certain highly  liquid investments  with
maturities  of less  than three months.  Short-term investments  consist of debt
securities with maturities beyond three months but less than twelve months.  The
short-term investments are classified as available-for-sale under the provisions
of  Statement of Financial Accounting Standards No. 115, "Accounting for Certain
Investments in Debt and Equity  Securities." Accordingly, these investments  are
stated at fair value.
 
3.  COMPUTATION OF NET INCOME AND PRO FORMA NET INCOME PER SHARE
    Net  income and pro forma net income  per common and common equivalent share
are computed  based on  the weighted  average of  common and  common  equivalent
shares  (redeemable convertible  preferred stock and  stock options) outstanding
during the period.
 
    Pursuant to Securities and Exchange Commission Staff Accounting Bulletin No.
83, common  and  common  equivalent  shares  issued  during  the  twelve  months
immediately preceding the initial public offering date (using the treasury stock
method  and the initial public  offering price per share)  have been included in
the calculation  of  common  and  common  equivalent  shares  as  if  they  were
outstanding for all periods presented.
 
4.  INCOME TAXES
    Prior to December 31, 1995, the Company's business was owned and operated by
Whittman-Hart,  L.P.,  a Delaware  limited  partnership, therefore,  federal and
certain state income tax  liabilities were the  responsibility of the  partners.
The  pro forma tax adjustment for the  six months ended June 30, 1995 represents
federal and additional state  income tax expense that  would have been  required
had the Company operated as a C corporation during that period.
 
5.  STOCKHOLDERS' EQUITY
    The  Company's Board  of Directors approved  a 4  for 1 split  of the common
stock in the form of a stock dividend effective April 3, 1996. All common  share
and  per share amounts  have been adjusted  retroactively to give  effect to the
stock split. Additionally, on April 3,  1996, the Company filed an Amendment  to
its  Certificate  of  Incorporation  effecting  an  increase  in  the  number of
authorized shares of common stock to 15,000,000 and authorizing 3,000,000 shares
of preferred stock. The authorized numbers of shares have been adjusted to  give
effect to these increases.
 
    On  May 8,  1996, the  Company completed an  initial public  offering of its
common stock in which  2,600,000 shares were sold  by the Company, resulting  in
net  proceeds of approximately $37.8 million.  In connection with such offering,
239,019 shares of  redeemable convertible  preferred stock  were converted  into
956,074  shares of common stock. All accrued and unpaid dividends related to the
redeemable convertible  preferred stock  were canceled  upon the  conversion  to
common stock.

6.  STOCK OPTIONS
    In  1995,  the  Company adopted  a  stock  option plan  under  which certain
employees may be granted  the right to  purchase shares of  common stock at  the
fair  market value on the date of grant.  Stock options may be exercised only to
the extent they  have vested  in accordance  with provisions  determined by  the
Board of Directors. In addition, the Company has from time to time granted stock
options  outside of the stock option plan. Stock option transactions for the six
months ended June 30, 1996 are summarized as follows:
