      Whittman-Hart, Uniwhale, Inc., a wholly owned subsidiary of Whittman-Hart,

      which USWeb/CKS will become a wholly owned subsidiary of Whittman-Hart;


    - A proposal to amend the Whittman-Hart charter to increase the number of
      authorized common shares from 75,000,000 shares to 500,000,000 shares.


    - A proposal to increase the number of authorized shares of common stock
      available for issuance under the Whittman-Hart 1995 Incentive Stock Plan

                  MERGER PROPOSED--YOUR VOTE IS VERY IMPORTANT

The Boards of Directors of Whittman-Hart and USWeb/CKS have approved a merger
agreement that provides for the merger of the two companies.

We are currently deciding on a new name for our combined company, which will
have its headquarters in Chicago and additional executive offices in San
Francisco and New York.

Upon completion of the merger, holders of USWeb/CKS common stock will receive
0.865 of a share of Whittman-Hart common stock for each USWeb/CKS share they
own. Whittman-Hart stockholders will continue to own their existing shares after
the merger.


We estimate that Whittman-Hart will issue approximately 81,482,000 shares of
Whittman-Hart common stock to USWeb/CKS stockholders in the merger. These shares
will represent approximately 57% of the outstanding shares of the combined
company's common stock after the merger. Existing Whittman-Hart stockholders
will hold approximately 43% of the outstanding shares of the combined company's
common stock after the merger. In addition, Whittman-Hart will issue shares in
the future to satisfy option, warrant, bonus and earn-out obligations of
USWeb/CKS.


We are asking stockholders of USWeb/CKS to approve the merger agreement and the
merger.

We are asking stockholders of Whittman-Hart to approve:

    - the issuance of Whittman-Hart common stock to the stockholders of
      USWeb/CKS in the merger,

    - an amendment to Whittman-Hart's charter to increase the number of
      authorized shares, and

    - an amendment to Whittman-Hart's 1995 Incentive Stock Plan to increase the
      number of shares of common stock authorized for issuance under the plan.

We cannot complete the merger unless the stockholders of USWeb/CKS approve the
merger proposal and the stockholders of Whittman-Hart approve the issuance of
shares in the merger and the increase in the number of authorized Whittman-Hart
shares. We can complete the merger whether or not the amendment to the
Whittman-Hart 1995 Incentive Stock Plan is approved. PLEASE SEE "RISK FACTORS"
BEGINNING ON PAGE 22 FOR A DISCUSSION OF CERTAIN FACTORS THAT YOU SHOULD
CONSIDER IN EVALUATING THE MERGER AND THE OTHER PROPOSALS.

                             QUESTIONS AND ANSWERS
                    ABOUT THE WHITTMAN-HART/USWEB/CKS MERGER

Q: WHY ARE THE TWO COMPANIES PROPOSING TO MERGE?

A: USWeb/CKS and Whittman-Hart both provide professional services that enable
   their customers to engage in e-business. We believe that market forces are
   driving our customers to require a comprehensive professional services
   solution that can satisfy their e-business needs for technology, strategy,
   marketing and creative work. The combined company will have a breadth of
   services and scale that can make it the leading provider of professional
   services to companies' e-business initiatives. We believe that this merger
   will allow us to accelerate long-term growth and provide added stockholder
   value. We note that achieving these anticipated benefits is subject to
   certain risks discussed on pages 22 to 29. To review the reasons for the
   merger and related uncertainties in greater detail, see pages 36 to 40.

Q: WHAT WILL I RECEIVE IN THE MERGER?

A: USWEB/CKS STOCKHOLDERS: You will be entitled to receive 0.865 of a share of
   Whittman-Hart common stock in exchange for each share of USWeb/CKS common
   stock you own. Whittman-Hart will not issue fractional shares. Instead, you
   will receive a payment equal to the market value of any fractional share. For
   example, if you currently own 100 shares of USWeb/CKS common stock, then
   after the merger you will be entitled to receive 86 shares of Whittman-Hart
   common stock and a check for the market value of the 0.5 fractional share of
   Whittman-Hart common stock.

    WHITTMAN-HART STOCKHOLDERS: You will retain the shares of Whittman-Hart
    common stock you currently own.


    On January 25, 2000, the closing price per share on the Nasdaq National
    Market of USWeb/CKS common stock was $45.56 and of Whittman-Hart common
    stock was $53.69.


Q: AS A STOCKHOLDER, HOW WILL THE MERGER AFFECT ME?

A: After the merger, you will own shares of a company that will own the combined
   businesses of both USWeb/CKS and Whittman-Hart. Each share of stock that you
   own will represent a smaller ownership percentage of a significantly larger
   company.

Q: WHAT ABOUT FUTURE DIVIDENDS?

A: Historically, neither USWeb/CKS nor Whittman-Hart has paid dividends. We do
   not expect that the combined company will pay any dividends in the
   foreseeable future.

Q: WHO WILL MANAGE THE COMBINED COMPANY AFTER THE MERGER?


A: Following the merger, the board of directors of the combined company will
   consist of nine directors: Robert Bernard, Chairman and Chief Executive
   Officer of Whittman-Hart; Robert Shaw, Chief Executive Officer of USWeb/CKS;
   four additional directors named by Whittman-Hart, all of whom are currently
   directors of Whittman-Hart: Paul D. Carbery, a general partner of Frontenac
   Company, W. Barry Moore, Vice Chairman of Kurt Salmon Associates, David P.
   Storch, Chief Executive Officer of AAR Corp., and Edward V. Szofer, President
   of Whittman-Hart; and three additional directors to be named by USWeb/CKS.
   Mr. Bernard will serve as the Chief Executive Officer and President of the
   combined company and Mr. Shaw will serve as the Chairman of the board of
   directors of the combined company.


                                       1
<PAGE>
Q: WHAT DO I NEED TO DO NOW?

A: After carefully reading and considering the information contained in this
   joint proxy statement/ prospectus, indicate on the enclosed proxy card how
   you want to vote, and sign and submit your proxy card in the enclosed return
   envelope as soon as possible so that your shares may be voted at the special
   meetings. If you sign and submit your proxy card but do not indicate how you
   want to vote, your shares will be voted in favor of the proposals shown on
   the card. IF YOU ABSTAIN OR DO NOT VOTE, IT WILL HAVE THE SAME EFFECT AS A
   VOTE AGAINST THE MERGER AGREEMENT AND MERGER IN THE CASE OF USWEB/CKS AND THE
   CHARTER AMENDMENT IN THE CASE OF WHITTMAN-HART. The boards of directors of
   USWeb/CKS and Whittman-Hart are not aware of any matters other than those set
   forth in this joint proxy statement/ prospectus that will be brought before
   their special meetings. If, however, other matters are properly presented at
   either special meeting, proxies will be voted in accordance with the
   discretion of the holders of such proxies.

Q: IF MY SHARES ARE HELD IN THE NAME OF MY BROKER, WILL MY BROKER VOTE MY SHARES
   FOR ME?

A: Your broker will vote your shares only if you provide instructions on how to
   vote. You should instruct your broker to vote your shares according to your
   directions. Without instructions, your shares will not be voted.

Q: CAN I CHANGE MY VOTE AFTER I HAVE SUBMITTED MY PROXY CARD?

A: You can change your vote at any time before your proxy is voted at the
   special meeting. You can do this in one of the following three ways:

    - You can send a written notice stating that you would like to revoke your
      proxy. Any such notice should be sent to the appropriate company at the
      address indicated below in time to be received before the special meeting.

    - You can complete and submit a new proxy card prior to or at the special
      meeting.

    - You can attend the special meeting and vote in person. Simply attending
      the meeting, however, will not revoke your proxy; you must vote at the
      special meeting.

    If you have instructed a broker to vote your shares, you must follow
    directions received from your broker to change your vote.

Q: SHOULD I SEND IN MY STOCK CERTIFICATE NOW?

A: No. After the merger is completed, we will send USWeb/CKS stockholders
   written instructions for exchanging their stock certificates. Whittman-Hart
   stockholders will keep their current certificates.

Q: WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

A: We are working towards completing the merger as quickly as possible. In
   addition to stockholder approvals, other conditions as described in the
   merger agreement, including the expiration or termination of the waiting
   periods under U.S. or foreign antitrust laws, must be satisfied or waived. We
   hope to complete the merger within a few days after the special meetings.

Q: WHAT ARE THE TAX CONSEQUENCES OF THE MERGER?

A: The exchange of shares by USWeb/CKS stockholders will be tax-free to
   USWeb/CKS stockholders for federal income tax purposes, except for taxes on
   cash received for a fractional share. The merger will be tax-free to
   Whittman-Hart stockholders for federal income tax purposes. To review the tax
   consequences to stockholders in greater detail, see pages 52 to 53.

    The merger agreement is attached as Annex A to this joint proxy
statement/prospectus. We encourage you to read the merger agreement because it
is the legal document that governs the merger.

    CONSIDERATION TO BE RECEIVED IN THE MERGER (see page 55)--Each share of
USWeb/CKS common stock outstanding before the merger will automatically be
converted into the right to receive 0.865 of a share of Whittman-Hart common
stock in the merger, subject to the payment of cash for fractional shares.

    CONVERSION OF USWEB/CKS STOCK OPTIONS AND WARRANTS (see page 55)--All
outstanding options and warrants to purchase USWeb/CKS common stock will be
assumed by Whittman-Hart and converted into options or warrants to purchase
Whittman-Hart common stock based on the exchange ratio of 0.865 of a share of
Whittman-Hart common stock for each share of USWeb/ CKS common stock.


    STOCK OWNERSHIP FOLLOWING THE MERGER--Based upon approximately 94,199,000
shares of USWeb/ CKS common stock issued and outstanding as of the record date,
approximately 81,482,000 shares of Whittman-Hart common stock will be issued to
holders of USWeb/CKS common stock in the merger.



    The existing holders of USWeb/CKS common stock will hold approximately 57%
of the combined company's common stock issued and outstanding after the merger.

of the combined company's common stock issued and outstanding after the merger.

    Upon the completion of the merger, certain unvested stock options held by

with respect to these matters for the benefit of USWeb/CKS's directors and
officers. There are limitations on the amount Whittman-Hart is required to spend
to maintain such insurance.

    CONDUCT OF BUSINESS--Whittman-Hart and USWeb/CKS are required to conduct
their business in the ordinary course consistent with past practice until the
effective time of the merger and, subject to certain exceptions, may not engage
in material transactions during this period.

    CERTAIN FEDERAL INCOME TAX CONSEQUENCES (see page 52)--We have structured
the merger to be a tax-free reorganization for federal income tax purposes. We
have conditioned the merger on receiving legal opinions that no gain or loss
will be recognized by USWeb/CKS stockholders on the exchange of USWeb/CKS common
stock for Whittman-Hart common stock, except to the extent that USWeb/CKS
stockholders receive cash in lieu of fractional shares.

    ACCOUNTING TREATMENT (see page 51)--The merger will be accounted for under
the purchase method of accounting.

    RIGHTS OF DISSENTING STOCKHOLDERS (see page 52)--Neither USWeb/CKS's nor
Whittman-Hart's stockholders are entitled to exercise dissenters' or appraisal
rights as a result of the merger or to demand payment for their shares under the
Delaware General Corporation Law.

    REGISTRATION STATEMENT ON FORM S-8--Promptly following the closing date,
Whittman-Hart will file a Registration Statement on Form S-8 under the
Securities Act covering the shares of Whittman-Hart common stock issuable with
respect to options to purchase USWeb/CKS common stock assumed by Whittman-Hart.

                         THE USWEB/CKS SPECIAL MEETING

    PURPOSE--The purpose of the USWeb/CKS special meeting is to vote on a
proposal to approve the merger agreement and the merger.
USWeb/CKS stockholders may also vote on any other matters that may be properly
brought before the USWeb/CKS special meeting.


    RECORD DATE AND VOTE REQUIRED--Only
USWeb/CKS stockholders of record at the close of business on January 25, 2000
are entitled to vote at the USWeb/CKS special meeting. The affirmative vote of a
majority of the outstanding shares of USWeb/CKS common stock is required to
approve the merger proposal. At the close of business on the USWeb/CKS record
date, there were approximately 94,199,000 shares of USWeb/CKS common stock
outstanding.


    USWEB/CKS VOTING AGREEMENTS (see page 54)--Whittman-Hart has entered into
agreements with three stockholders of USWeb/CKS requiring them to vote all
shares of USWeb/CKS common stock they beneficially own in favor of the merger. A
form of these agreements is attached as Annex D. In total, these shares
represent approximately 2% of the outstanding USWeb/CKS common stock.

    This joint proxy statement/prospectus and the accompanying notice of special
meeting of stockholders was mailed to all USWeb/CKS stockholders of record as of
the USWeb/CKS record date and constitutes notice of the USWeb/CKS special
meeting in conformity with the requirements of the Delaware General Corporation

    acquisitions were consummated during 1999 and were accounted for using the
    pooling-of-interests method of accounting. Prior years' information has not
    been restated to reflect the acquisitions as the acquired businesses,
    considered in the aggregate, are not significant.

                                    OVERVIEW



    On December 12, 1999, Whittman-Hart and USWeb/CKS entered into a merger
agreement. Under the terms of the merger agreement, and assuming
93,000,000 shares of USWeb/CKS common stock outstanding as of December 31, 1999,
approximately 80,445,000 shares of Whittman-Hart common stock will be exchanged
in the merger for all of the outstanding common stock of USWeb/CKS. In addition,
employee options to purchase approximately 26,865,000 shares of USWeb/CKS common
stock and warrants to purchase approximately 2,388,000 shares of USWeb/CKS
common stock will be assumed by Whittman-Hart and will become options or
warrants to purchase Whittman-Hart common stock based on the exchange ratio.
This transaction will be accounted for as a purchase business combination in
accordance with Accounting Principles Board ("APB") Opinion No. 16, "Business
Combinations." Pursuant to the terms of the merger agreement, the stockholders
of USWeb/CKS will receive 0.865 of a share of Whittman-Hart common stock in
exchange for each share of USWeb/CKS common stock held. All outstanding employee
stock options and warrants will be converted into options or warrants to
purchase Whittman-Hart common stock based on the exchange ratio of 0.865 of a
share of Whittman-Hart common stock for each share of USWeb/CKS common stock.
Total consideration for the transaction is estimated as follows:

    The value of the options and warrants included in the purchase price was
determined using the Black-Scholes option pricing model.

    The Financial Accounting Standards Board (the "FASB") is in the process of
reviewing the existing accounting rules governing employee stock option
accounting, APB Opinion No. 25, "Accounting for Stock Issued to Employees." The
objective of the FASB's project is to issue a FASB interpretation that provides
guidance on certain practice issues related to the application of APB Opinion
No. 25. Included in this project is the treatment of stock options and warrants
exchanged in a purchase business combination. An exposure draft of the
interpretation contemplates that only options that have vested are to be
included in the purchase price. The computation of the component of the purchase
price related to options and warrants may change depending on the FASB's
interpretation.


    On September 3, 1999, USWeb/CKS acquired Mitchell Madison Group ("MMG") in a
transaction accounted for as a purchase business combination. Total
consideration for this acquisition was approximately $217,867 comprising $10,000
in cash, 7,210,160 shares of USWeb/CKS common stock valued at $170,882, warrants
to purchase 1,666,500 shares of USWeb/CKS common stock issued to financial
advisors valued at $14,369, and other acquisition costs aggregating
approximately $22,616. The acquisition of MMG also provides for additional
payments of up to 6,810,160 shares of USWeb/CKS common stock payable over a
two-year period.


    The accompanying unaudited pro forma combined balance sheet combines the
unaudited consolidated balance sheet of Whittman-Hart as of September 30, 1999,
with the unaudited consolidated balance sheet of USWeb/CKS as of the same date,
and gives effect to the acquisition of USWeb/CKS as if it occurred on such date.

    The accompanying unaudited pro forma combined statements of operations
combine Whittman-Hart's statements of operations for the year ended
December 31, 1998, and for the nine months ended September 30, 1999, with the
statements of operations of USWeb/CKS for the same periods and gives effect to
the acquisition as if it occurred on January 1, 1998.

    These unaudited pro forma combined financial statements are presented for
illustrative purposes only and are not necessarily indicative of the combined
financial position or results of operations in future periods or the results
that actually would have been realized had Whittman-Hart and USWeb/CKS been a
combined company during the periods presented.

PRO FORMA ADJUSTMENTS

    On December 12, 1999, Whittman-Hart and USWeb/CKS entered into the merger
agreement, for total consideration of $6,503,000. The acquisition of USWeb/CKS
by Whittman-Hart will be accounted for as a purchase business combination and,
accordingly, the purchase price will be allocated to the tangible and
identifiable intangible assets acquired and liabilities assumed on the basis of
their estimated fair values on the effective date of the merger. The valuation
of the intangible assets acquired will be determined by an independent appraiser
and are expected to include workforce in place and customer lists. Such
valuations and studies are not yet complete. Accordingly, the final allocation
may be different from that reflected below. Assuming that the acquisition of
USWeb/CKS had occurred on September 30, 1999, the purchase price allocation
would have been as follows:

<TABLE>

</TABLE>

(A) Reflects the excess of acquisition price paid for USWeb/CKS by
    Whittman-Hart, over the estimated fair value of net assets acquired.

    The excess of purchase price over tangible and identifiable intangible
    assets acquired and liabilities assumed will be recorded as goodwill.
    Identifiable intangible assets are expected to include workforce in place
    and customer lists. An independent valuation of identifiable intangible
    assets is currently being performed by an independent appraiser; however,
    the valuation has not yet been completed.

(B) Reflects the accrual of estimated costs resulting from the acquisition of
    USWeb/CKS by Whittman-Hart. Such costs are estimated to be $75,000, and
    include direct transaction costs, primarily for financial advisory and legal
    fees, lease termination costs and severance costs. The estimated costs are
    reflected in the unaudited pro forma combined balance sheet as a component
    of purchase price.

    Estimated transaction costs include the following:

<TABLE>
<S>                                                           <C>

</TABLE>

    Actual amounts ultimately incurred could differ from estimated amounts due
    to the actual time incurred by professional advisors, including accountants
    and attorneys, actual lease termination costs, actual severance costs, and
    the final purchase price.

(C) Reflects amortization expense of intangible assets resulting from the
    acquisition of USWeb/CKS by Whittman-Hart as if such acquisition had
    occurred on January 1, 1998, using estimated useful lives of between 5 and
    10 years. A final valuation has not yet been completed, and the actual
    amounts allocated to intangible assets and their respective lives may change
    depending on the final valuation report issued by an independent appraiser.


(D) Reflects the stock compensation charge related to the issuance of up to
    6,810,160 additional shares of USWeb/CKS common stock payable to the MMG
    shareholders who remain as employees of USWeb/ CKS on the first and the
    second closing date anniversaries of the acquisition of MMG's assets. This

    charge is being amortized over its vesting period of 24 months and is
    allocated between cost of revenues and operating expenses based upon
    classification of the related employees.

(E) Reflects amortization expense of intangible assets resulting from the
    purchase business combination of MMG as if the business combination had
    occurred on January 1, 1998, using estimated useful lives of between 5 and
    7 years.

(F) Eliminates a 1% minority interest as a result of the purchase of 100% of
    MMG's capital ownership.

(G) Pro forma weighted average shares used in the calculation of Whittman-Hart
    and USWeb/CKS pro forma combined net loss per share have been computed by
    adding Whittman-Hart's historical weighted average shares outstanding to
    USWeb/CKS's pro forma weighted average shares outstanding converted to give
    effect to the exchange ratio of 0.865.

    Pro forma weighted average shares used in the calculation of USWeb/CKS pro
    forma combined net loss per share include common stock issued to MMG upon
    the acquisition of MMG's assets by USWeb/CKS, as well as additional shares
    issuable to MMG employees who remain in the employment of USWeb/CKS at the
    first and second closing date anniversaries of the acquisition assuming that
    the acquisition took place on January 1, 1998.

(H) No income tax benefit related to the amortization of intangible assets
    created by the merger has been recognized in the pro forma combined
    statement of operations as the ultimate realization of any benefit is not
    certain.

(I) To conform presentation of recruiting expenses.

COMPARATIVE PER SHARE DATA

    We have summarized below selected historical per share data of Whittman-Hart
and USWeb/CKS and combined per share data on an unaudited pro forma basis after
giving effect to the merger accounted for using the purchase method of
accounting and assuming that 0.865 of a share of Whittman-Hart common stock was
issued in exchange for each outstanding share of USWeb/CKS common stock (other
than shares owned by Whittman-Hart and its subsidiaries or by USWeb/CKS).


    You should read this data in conjunction with each of our historical audited
consolidated financial statements and the related notes, that are included in
each of our Annual Reports and other financial information included in our
filings with the SEC. See "Where You Can Find More Information" on page 72.


    This unaudited pro forma combined financial data does not necessarily
indicate the operating results that would have been achieved had the merger been

COMPARATIVE MARKET PRICE DATA


    At the close of business on each company's record date, there were
approximately 1,310 holders of record of Whittman-Hart common stock and
approximately 710 holders of record of USWeb/CKS common stock. Following
completion of the merger, USWeb/CKS common stock will cease to be quoted on
Nasdaq.


    Neither of us has ever paid any cash dividends on our stock. We anticipate
that the combined company, for the foreseeable future, will retain any earnings
for use in its operations.


    On December 10, 1999, the last trading day prior to the announcement of the
execution of the merger agreement, the closing price per share of Whittman-Hart
common stock was $79.25 and the closing price per share of USWeb/CKS common
stock was $50.875. On January 25, 2000, the last trading day prior to the
printing of this joint proxy statement/prospectus, the closing price per share
of Whittman-Hart common stock was $53.688 and the closing price per share of
USWeb/CKS common stock was $45.563. The market prices of shares of Whittman-Hart
common stock and USWeb/CKS common stock are subject to fluctuations. As a
result, Whittman-Hart and USWeb/CKS stockholders are urged to obtain current
market quotations.

RECENT DEVELOPMENTS



    Both Whittman-Hart and USWEB/CKS have issued press releases stating their
results of operations for the fourth quarter of 1999. Each of us has filed this
information with the SEC. See "Where You Can Find More Information" on page 72.


                                       21
<PAGE>
                                  RISK FACTORS

    You should consider the following risks in deciding whether to approve the
proposals related to the merger and the merger agreement. These matters should
be considered along with the other information included in this joint proxy
statement/prospectus. We have separated the risks into two groups: risks
relating to the merger and risks relating to the combined company.

                          RISKS RELATING TO THE MERGER

INTEGRATING WHITTMAN-HART AND USWEB/CKS MAY BE DIFFICULT

    After the merger, the combined company will need to efficiently and promptly
integrate the two companies' operations to achieve the anticipated benefits of
the merger. Failure to successfully integrate our businesses could have a
negative effect on the combined company and prevent us from achieving the
anticipated benefits of the merger.

    Certain key elements of our businesses need to be integrated, including:

    - management and other professional personnel;

    - technical and creative service offerings;

    - sales and marketing efforts; and

    - financial, accounting and other operational controls, procedures,
      information systems and policies.

The integration process will be further complicated by the need to integrate
widely dispersed operations, multiple executive offices and different corporate
cultures. This integration may not be accomplished in an efficient or effective
manner, if at all. The integration process will require the dedication of
management and other personnel, which may distract their attention from the
conduct of day-to-day business activities. The integration of Whittman-Hart and
USWeb/CKS will be made more difficult by the large number of other businesses
recently acquired by the two companies and the continuing challenges of
integrating some of these businesses. Finally, neither of us has attempted an
acquisition with the scope or magnitude of the planned merger. Expenses
associated with ongoing integration of the companies are likely to have a
negative effect on operating results of the combined entity at least through
December 31, 2000.

THE MARKET PRICES OF OUR COMPANIES' STOCK PRICES MAY FLUCTUATE, BUT THE EXCHANGE
  RATIO IS FIXED

    As a result of the merger, each outstanding share of USWeb/CKS's common
stock held by the USWeb/CKS stockholders (other than by Whittman-Hart and its
subsidiaries and by USWeb/CKS) will be converted into the right to receive 0.865
of a share of Whittman-Hart common stock. Because the exchange ratio is fixed
and will not increase or decrease with fluctuations in the market price of
Whittman-Hart common stock or USWeb/CKS common stock, the specific value of the
stock to be received by USWeb/CKS stockholders in the merger will depend on the
market price of the Whittman-Hart common stock at the completion of the merger.
We advise USWeb/CKS stockholders to obtain recent market quotations for
Whittman-Hart common stock and USWeb/CKS common stock. You should note that the
Whittman-Hart common stock and USWeb/CKS common stock historically have been
subject to price volatility. We have included the market prices of the
Whittman-Hart common stock and USWeb/CKS common stock as of a recent date in
this joint proxy statement/prospectus on page 21. However, we cannot accurately
predict what the market prices of the Whittman-Hart common stock or USWeb/CKS
common stock will be at the closing date.

WE MUST RETAIN KEY PERSONNEL AND THEY MUST WORK TOGETHER EFFECTIVELY

    The success of the combined company will depend upon the retention of senior
executives and other key employees who are critical to the continued
advancement, development and support of our services,

                                       22
<PAGE>
ongoing sales and marketing efforts. The loss of the services of any key
personnel or of any significant group of employees could negatively affect the
combined company's business and prospects. As often occurs with mergers of
technology/services companies, during the pre-merger and integration phases
competitors may intensify their efforts to recruit key employees. Employee
uncertainty regarding the effects of the merger could also cause increased
turnover. The recent decline in stock prices of both Whittman-Hart and USWeb/CKS
may have the effect of decreasing the incentive value of stock options or other
equity held by employees and thereby increase the risk of employee turnover. The
combined company may not be able to retain key creative, technical, sales or
marketing personnel before or after the merger.

    The combined company's success largely depends on the ability of its
executive officers and other members of senior management to operate effectively
in their roles in the newly combined company. If the combined company's
management does not succeed in their roles or the combined company is not able
to efficiently allocate management responsibilities and cause its officers and
senior managers to operate effectively as a group, its business could be
negatively affected.

WE COULD LOSE CLIENTS AS A RESULT OF UNCERTAINTY REGARDING THE MERGER

    Uncertainty regarding the merger and the ability of Whittman-Hart and
USWeb/CKS to effectively integrate their operations without significant
reduction in quality of service could lead some customers to select other
vendors. The loss of business from significant clients could have a negative
effect on the combined company's business.

WE MUST BUILD RECOGNITION AND CUSTOMER ACCEPTANCE OF NEW BRANDS

    We have each invested significant efforts in building brand recognition and
customer acceptance of our brand names. We believe that transferring market
acceptance for the Whittman-Hart and USWeb/CKS brands to the combined company
brands will be an important aspect of its efforts to retain and attract clients.
Promoting and maintaining the combined company brands will depend largely on the
success of the combined company's marketing efforts and the ability of the
combined company to provide high quality, reliable and cost-effective services.
These efforts will require significant expenses, which will affect the combined
company's results of operations. In addition, although we intend to centralize
the combined company's marketing efforts, a significant part of its client
services will continue to be provided through individual consulting offices.
Client dissatisfaction with the performance of a single office could diminish
the value of the combined company brands.

THE MERGER WILL RESULT IN SUBSTANTIAL COSTS WHETHER OR NOT COMPLETED

    The merger will result in significant costs to Whittman-Hart and USWeb/CKS.
Excluding costs associated with combining the operations of the two companies
and costs associated with promoting and maintaining the new brands of the
combined company, which costs are difficult to estimate, direct transaction
costs are estimated at approximately $75 million. We expect these costs to
consist primarily of fees for investment bankers, attorneys, accountants, filing
fees, financial printing, and severance benefits and costs associated with
discontinuing some redundant business activities. The aggregate amount of these
costs may be greater than currently anticipated. The substantial majority of
these costs will be incurred whether or not the merger is completed.

IF THE MERGER IS NOT COMPLETED THE COMPANIES' STOCK PRICES COULD DECLINE

    The obligations of Whittman-Hart and USWeb/CKS to complete the merger are
subject to the satisfaction or waiver of certain conditions. See page 56 for a
discussion of these conditions. These conditions might not be satisfied or
waived and the merger might not be completed. Noncompletion of the merger would
likely have a negative effect on the stock trading price of one or both parties.

<PAGE>
                     RISKS RELATING TO THE COMBINED COMPANY

OUR QUARTERLY RESULTS MAY FLUCTUATE, WHICH MAY LEAD TO REDUCED PRICES FOR OUR
  STOCK

    Each of Whittman-Hart's and USWeb/CKS's operating results have fluctuated in
the past and the combined company's operating results are likely to fluctuate in
the future as a result of a variety of factors, many of which will be outside of
the combined company's control. Some of these factors include:

    - timing of the completion, material reduction or cancellation of major
      projects or the loss of a major client;

    - the amount and timing of the receipt of new business;

    - timing of hiring or loss of personnel;

    - the cost and timing of the opening or closing of an office;

    - the amount and the relative mix of high-margin creative or strategy
      consulting projects as compared to lower margin projects;

    - capital expenditures and other costs relating to the expansion of
      operations;

    - the level of demand for Intranet, Extranet and Web site development;

    - the productivity of consultants;

    - the ability to maintain adequate staffing to service clients effectively;

    - the cost of advertising and related media;

    - the amount and timing of expenditures by clients for professional
      services;

    - the introduction of new products or services by competitors;

    - pricing changes in the industry;

    - the relative mix of lower cost full-time employees versus higher cost
      independent contractors;

    - technical difficulties with respect to the use of the Internet;

    - economic conditions specific to Internet technology usage;

    - government regulation and legal developments regarding the use of the
      Internet; and

    - general economic conditions.

    The combined company may also experience seasonality in its business,
resulting in diminished revenues as a consequence of decreased demand for
professional services during summer and year-end vacation and holiday periods.
Due to all of these factors, the combined company's operating results in any
given quarter may fall below the expectations of securities analysts and
investors. In such event, the trading price of the combined company's common
stock would likely be significantly and negatively affected and litigation may
ensue.

    Whittman-Hart's and USWeb/CKS's historical financial data is of limited
value in planning future operating expenses. Accordingly, the combined company's
expense levels will be based in part on its expectations concerning future
revenues and will be fixed to a large extent. The combined company will be
unable to adjust spending in a timely manner to compensate for any unexpected
shortfall in revenues. Accordingly, a significant shortfall in demand for
services could have an immediate and significant negative effect on the combined
company's business and results of operations.

OUR STOCK PRICES ARE VOLATILE AND THE COMBINED COMPANY'S STOCK COULD DECLINE IN
  VALUE

    The stock market, which has recently been at or near historic highs, has
experienced extreme price and volume fluctuations that have particularly
affected the market prices of equity securities of many technology companies and
that often have been unrelated to the operating performance of those 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. Such litigation could result in substantial costs and a
diversion of management's attention and resources, which would have a negative
effect on the combined company's business, financial condition and results of
operations.

THE MERGER WILL DILUTE YOUR PERCENTAGE OWNERSHIP


    The merger will dilute the percentage ownership held by the stockholders of
each of Whittman-Hart and USWeb/CKS in the combined company when compared to
their ownership in each company prior to the merger. Based upon the estimated
capitalization of Whittman-Hart and USWeb/CKS as of the record date,
approximately 81,482,000 shares of common stock will be issued in the merger,
and the USWeb/CKS stockholders will hold approximately 57% of the outstanding
shares of the combined company's common stock after giving effect to such
issuance. Each of Whittman-Hart and USWeb/CKS have outstanding a large number of
options to purchase common stock of their company, many of which have exercise
prices significantly below the market price of each company's respective common
stock as of the date of this joint proxy statement/prospectus. When the merger
is completed, the USWeb/CKS options will be converted into options to purchase
shares of common stock in the combined company. To the extent these options are
exercised, there will be further dilution. Pursuant to its prior acquisition
agreements, USWeb/CKS may be required to issue substantial additional "earn out"
stock to the former stockholders of acquired companies as well as stock options
and stock bonuses to the employees of the acquired companies who have remained
employees of USWeb/CKS. These obligations will continue following the merger.


TO SUCCEED, WE MUST RECRUIT AND RETAIN SKILLED PROFESSIONALS, WHO ARE IN SHORT
  SUPPLY

    The combined company's business of delivering Internet professional services
is labor intensive. Accordingly, its success depends in large part on its
ability to identify, hire, train and retain consulting professionals who can
provide the Internet strategy, technology, and marketing and creative skills
required by clients. The inability to attract and retain the necessary
technical, marketing and managerial personnel would have a negative effect on
the combined company's business. There is currently a shortage of such
personnel, and this shortage is likely to continue for the foreseeable future.
The combined company will encounter intense competition for qualified personnel
from other companies, and may not be able to identify, hire, train or retain
other highly qualified technical, marketing and managerial personnel in the
future.

OUR SUCCESS DEPENDS ON OUR ABILITY TO MANAGE GROWTH

    Each of Whittman-Hart and USWeb/CKS has experienced recent rapid growth and
is subject to the risks inherent in the expansion and growth of a business
enterprise. This significant growth, if sustained, will continue to place a
substantial strain on our operational and administrative resources and to
increase the level of responsibility for our existing and new management
personnel. To manage our growth effectively, we will need to further develop our
operating, MIS, accounting and financial systems and to expand, train and manage
our employee base. The management skills and systems currently in place may not
be adequate if the combined company continues to grow.

OUR INTERNATIONAL OPERATIONS ARE DIFFICULT TO MANAGE

    Upon completion of the merger, the combined company will have 27 offices
outside the United States. If revenues from international consulting offices are
not adequate to offset the expenses of establishing

                                       25
<PAGE>
and maintaining international operations and of localizing the combined
company's marketing programs, the combined company's business and results of
operations could be negatively affected. In addition to the uncertainty as to
the combined company's ability to generate revenues from foreign operations and
expand its international presence, there are certain risks inherent in doing
business on an international level, including any of the following factors which
could negatively affect the combined company's international operations:

    - unexpected changes in regulatory requirements, export and import
      restrictions, tariffs and other trade barriers;

    - difficulties in staffing and managing foreign operations;

    - potentially adverse differences in business customs, practices and norms;

    - longer payment cycles;

    - problems in collecting accounts receivable;

    - political instability;

    - fluctuations in currency exchange rates;

    - software piracy;

    - seasonal reductions in business activity; and

    - potentially adverse tax consequences.

THE MARKET IN WHICH WE COMPETE IS HIGHLY COMPETITIVE AND HAS LOW BARRIERS TO
  ENTRY

    The market for Internet professional services is relatively new, intensely
competitive, rapidly evolving and subject to rapid technological change. The
combined company expects competition to intensify and increase in the future.
The combined company's competitors can be divided into several groups:

    - large information technology consulting service providers such as Andersen
      Consulting, Cambridge Technology Partners and Electronic Data Systems
      Corporation;

    - the consulting divisions of computer hardware vendors such as
      International Business Machines Corporation, Compaq Computer Corp. and
      Hewlett-Packard Company;

    - Internet integrators and Web presence providers such as Agency.com, iXL
      Enterprises, Inc., Organic Online, Inc., Proxicom Inc., Sapient
      Corporation, Scient Corporation, and Viant Corporation; and

    - advertising and media agencies such as Ogilvy & Mather, Young & Rubicam,
      and Foote, Cone & Belding.

Many of the combined company's current and potential competitors have longer
operating histories, larger installed customer bases, longer relationships with
clients and significantly greater financial, technical, marketing and public
relations resources than the combined company and could decide at any time to
increase their resource commitments to the combined company's target markets. In
addition, the market for Intranet, Extranet and Web site development is
relatively new and subject to continuing definition, and, as a result, may
better position the combined company's competitors to compete in this market as
it matures. As a strategic response to changes in the competitive environment,
the combined company may from time to time make pricing, service, technology or
marketing decisions or business or technology acquisitions that could have a
negative effect on the combined company's business and results of operations.

                                       26
<PAGE>
    In addition, the combined company's ability to maintain its existing client
relationships and generate new clients will depend to a significant degree on
the quality of its services and its reputation among its clients and potential
clients, as compared with its competitors. To the extent the combined company
loses clients to its competitors because of dissatisfaction with the combined
company's services or its reputation is negatively affected for any other
reason, the combined company's business could be negatively affected.

    There are relatively low barriers to entry into the combined company's
business. Because professional services firms such as Whittman-Hart and
USWeb/CKS rely on the skill of their personnel and the quality of their client
service, they have no patented technology that would preclude or inhibit
competitors from entering their markets. The combined company is likely to face
additional competition from new entrants into the market in the future. Existing
or future competitors may develop or offer services that provide significant
performance, price, creative or other advantages over those offered by the
combined company, which could have a negative effect on the combined company's
business and prospects.

WE RELY ON STRATEGIC RELATIONSHIPS THAT COULD BE TERMINATED EASILY

    The combined company will have a number of strategic relationships with
leading hardware and software companies, including 3Com Corporation,
J.D. Edwards & Company, Microsoft Corporation, Novell, Inc., and Siebel
Systems, Inc. The loss of any one of these strategic relationships would deprive
the combined company of the opportunity to gain early access to leading-edge
technology, cooperatively market products with the vendor, cross-sell additional
services and gain enhanced access to vendor training and support. Maintenance of
the combined company's strategic relationships is based primarily on an ongoing
mutual business opportunity and a good overall working relationship. The legal
contracts associated with these relationships would not be sufficient to force
the strategic relationship to continue effectively if the strategic partner
wanted to terminate the relationship. In the event that any strategic
relationship is terminated, the combined company's business may be negatively
affected.

THE INTERNET ECONOMY AND THE MARKET FOR E-COMMERCE SOLUTIONS IS STILL DEVELOPING

    We expect the combined company to derive a substantial portion of its
revenues from services that depend upon the adoption of Internet solutions and
the continued development of the World Wide Web, the Internet and e-commerce.
The Internet has experienced, and is expected to continue to experience,
significant growth in the number of users and volume of traffic. The Internet
infrastructure may not continue to be able to support the demands placed on it
by this continued growth. In addition, critical issues concerning the use of
Internet and e-commerce solutions, including security, reliability, cost, ease
of deployment and administration and quality of service, remain unresolved and
may affect the acceptance of these technologies to operate a business, expand
product marketing, improve corporate communications and increase business
efficiencies. The adoption of Internet solutions for these purposes can be
capital intensive and generally requires the acceptance of a new way of
conducting business and exchanging information. If critical issues concerning
the ability of Internet solutions to improve business positioning and processes
are not resolved or if the necessary infrastructure is not developed, the
combined company's business and prospects will be negatively affected.

    Even if these issues are resolved, businesses may not elect to outsource the
design, development and maintenance of their Web sites to Internet professional
services firms. If independent providers of Internet professional services prove
to be unreliable, ineffective or too expensive, or if software companies develop
tools that are sufficiently user-friendly and cost-effective, enterprises may
choose to design, develop or maintain all or part of their Intranets, Extranets
or Web sites themselves. If the market for such services does not continue to
develop or develops more slowly than expected, or if the combined company's
services do not achieve market acceptance, its business will be negatively
affected.

                                       27
<PAGE>
THE INFRINGEMENT OR MISUSE OF INTELLECTUAL PROPERTY RIGHTS COULD HARM OUR
  BUSINESS

    Each of Whittman-Hart and USWeb/CKS regards its intellectual property
rights, such as copyrights, trademarks, trade secrets, practices and tools, as
important to the success of the combined company. To protect their intellectual
property rights, Whittman-Hart and USWeb/CKS each rely on a combination of
trademark and copyright law, trade secret protection and confidentiality
agreements and other contractual arrangements with their employees, affiliates,
clients, strategic partners, acquisition targets and others. Effective
trademark, copyright and trade secret protection may not be available in every
country in which the combined company intends to offer its services. The steps
taken by Whittman-Hart or USWeb/CKS to protect their intellectual property
rights may not be adequate, third parties may infringe or misappropriate the
combined company's intellectual property rights or the combined company may not
be able to detect unauthorized use and take appropriate steps to enforce its
rights. In addition, other parties may assert infringement claims against the
combined company. Such claims, regardless of merit, could result in the
expenditure of significant financial and managerial resources. Further, an
increasing number of patents are being issued to third parties regarding
Internet business processes. Future patents may limit the combined company's
ability to use processes covered by such patents or expose the combined company
to claims of patent infringement or otherwise require the combined company to
seek to obtain related licenses. Such licenses may not be available on
acceptable terms. The failure to obtain such licenses on acceptable terms could
have a negative effect on the combined company's business.

IF WE DO NOT PERFORM TO OUR CLIENTS' EXPECTATIONS, WE FACE POTENTIAL LIABILITY

    Many of our consulting engagements involve the development, implementation
and maintenance of applications that are critical to the operations of our
clients' businesses. The combined company's failure or inability to meet a
client's expectations in the performance of its services could injure the
combined company's business reputation or result in a claim for substantial
damages against the combined company, regardless of its responsibility for such
failure. In addition, each of us possesses technologies and content that may
include confidential or proprietary client information. Although each of us has
implemented policies to prevent such client information from being disclosed to
unauthorized parties or used inappropriately, any such unauthorized disclosure
or use could result in a claim for substantial damages. We have each attempted
to contractually limit our damages arising from negligent acts, errors, mistakes
or omissions in rendering professional services. However, these contractual
protections may not be enforceable or may not otherwise protect the combined
company from liability for damages. Although each of us maintains general
liability insurance coverage, including coverage for errors and omissions, such
coverage may not continue to be available on reasonable terms or may not be
available in amounts sufficient to cover one or more large claims, or the
insurer may disclaim coverage as to any future claim. The successful assertion
of one or more large claims against the combined company that are not covered by
insurance or result in changes to any of our insurance policies, including
premium increases or deductible or co-insurance requirements, could negatively
affect the combined company's business and financial condition.

ONE STOCKHOLDER WILL HAVE SIGNIFICANT INFLUENCE OVER THE COMBINED COMPANY

    Robert Bernard, who will be the Chief Executive Officer and President of the
combined company, will beneficially own approximately 9% of the combined
company's common stock immediately following the merger. As a result, Mr.
Bernard will be able to exercise significant influence over matters requiring
stockholder approval, including the election of directors and approval of
significant corporate transactions. Such concentration of ownership may also
have the effect of delaying or preventing a change in control of the combined
company.

                                       28
<PAGE>
THE ORGANIZATIONAL DOCUMENTS OF THE COMBINED COMPANY AND CURRENT DELAWARE LAW
MAY DETER POTENTIALLY BENEFICIAL TAKEOVER ATTEMPTS

    The combined 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, deter 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. The combined company's
directors will be divided into three classes and elected to serve staggered
three-year terms. The combined company's board of directors will be 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 combined
company by means of a tender offer, merger, proxy contest or otherwise. In
addition, this "blank-check" preferred stock, and any issuance thereof, may
significantly decrease the market price of the common stock.

    This joint proxy statement/prospectus contains or incorporates by reference
"forward-looking statements" within the "safe harbor" provisions of the Private
Securities Litigation Reform Act of 1995 about Whittman-Hart's and USWeb/CKS's
businesses and the expected impact of the merger. These statements include,

the proposal to approve and adopt the merger agreement and the merger. Holders
of USWeb/CKS common stock may also vote on any other matters that may come
before the USWeb/CKS special meeting including the approval of any adjournment
or postponement of the special meeting. The merger will occur only if the
proposal is approved.


THE USWEB/CKS BOARD OF DIRECTORS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND
THE MERGER, AND RECOMMENDS A VOTE "FOR" ADOPTION AND APPROVAL OF THE MERGER
AGREEMENT AND "FOR" APPROVAL OF THE MERGER.


PROXIES

    The USWeb/CKS proxy accompanying this joint proxy statement/prospectus is
being solicited on behalf of the USWeb/CKS board of directors for use at the
USWeb/CKS special meeting. You may vote in person at the meeting or by proxy. We
recommend you vote by proxy even if you plan to attend the meeting. You can
always change your vote at the meeting. Voting instructions are included on your
proxy card. If you properly give your proxy and submit it to us in time to vote,
one of the individuals named as your proxy will vote your shares as you have
directed. You may vote for or against the proposal submitted at the meeting or
abstain from voting. In order to vote by proxy, complete, sign, date and return
your proxy card in the enclosed envelope. If you hold shares through a broker or
other custodian, please check the voting form used by that firm to see if it
offers telephone or Internet voting. If you submit your proxy but do not make
specific choices, your proxy will follow the board's recommendation and vote
your shares for the merger proposal and in its discretion as to any other
business that may properly come before the meeting.

DATE, TIME AND PLACE OF MEETING


    The USWeb/CKS special meeting will be held on Monday, February 28, 2000 at
9:00 a.m., local time, at the offices of USWeb Corporation, 2880 Lakeside Drive,
Suite 300, Santa Clara, California 95054.


RECORD DATE AND OUTSTANDING SHARES


    Only holders of record of USWeb/CKS common stock at the close of business on
January 25, 2000, the USWeb/CKS record date, are entitled to notice of and to
vote at the USWeb/CKS special meeting. At the close of business on the USWeb/CKS
record date, there were approximately 94,199,000 shares of USWeb/ CKS common
stock outstanding. Each holder of record of USWeb/CKS common stock on the USWeb/
CKS record date will be entitled to one vote for each share held on all matters
to be voted upon at the USWeb/CKS special meeting.


VOTE REQUIRED

    A quorum of stockholders is necessary to hold a valid meeting. The presence,
in person or by properly executed proxy, of the holders of a majority of the
outstanding shares of USWeb/CKS common stock is necessary to constitute a
quorum. Abstentions and broker "non-votes" count as present for establishing a
quorum. A broker non-vote occurs when a broker is not permitted to vote on that
item without instructions from the beneficial owner of the shares and no
instruction is given. Approval of the USWeb/CKS proposal requires the
affirmative vote of a majority of the shares of USWeb/CKS common stock
outstanding on the record date. Abstentions and broker non-votes have the same
effect as a vote against the USWeb/CKS merger proposal.

                                       31
<PAGE>

    As of the record date for the special meeting, directors and executive
officers of USWeb/CKS held approximately 2,125,000 shares of USWeb/CKS common
stock. All directors and executive officers are expected to vote in favor of the
USWeb/CKS proposals.



    MMG LLC, a Cayman Islands limited liability company, owns approximately 7.6%
of the outstanding shares of USWeb/CKS. Each of the three members of the board
of directors of MMG are employees of USWeb/CKS. MMG is expected to vote in favor
of the USWeb/CKS proposals.


    Robert Shaw, USWeb/CKS's Chief Executive Officer, Mark Kvamme, Chairman of
the Board of USWeb/CKS, and Robert Hoff, a director of USWeb/CKS, have signed
stockholder agreements with Whittman-Hart, pursuant to which they have agreed to
vote shares of USWeb/CKS common stock they beneficially own, representing
approximately 2% of the total outstanding shares of USWeb/CKS common stock, in
favor of the merger.

REVOCABILITY OF PROXIES

    You may revoke your proxy before it is voted by:

    - submitting a new proxy with a later date,

    - notifying your company's secretary in writing before or at the meeting
      that you have revoked your proxy, or

    - voting in person at the meeting.

    If you have instructed a broker to vote your shares, you must follow
directions received from your broker to change your vote.

PROXY SOLICITATION

    This joint proxy statement/prospectus was mailed to all USWeb/CKS
stockholders of record on the USWeb/CKS record date and constitutes notice of
the USWeb/CKS special meeting in conformity with the requirements of the
Delaware General Corporation Law.

    The cost of the solicitation of proxies from holders of USWeb/CKS common
stock and all related costs will be borne by USWeb/CKS. The companies have
jointly engaged the services of a proxy solicitation firm, the costs of which
will be shared. In addition, USWeb/CKS may reimburse brokerage firms and other
persons representing beneficial owners of its shares for their expenses in
forwarding solicitation materials to such beneficial owners. Original
solicitation of proxies by mail may be supplemented by telephone, telegram or
personal solicitation by directors, officers or other employees of USWeb/CKS. No
additional compensation will be paid to directors, officers or other employees
for such services.

                       THE WHITTMAN-HART SPECIAL MEETING

PURPOSE OF THE WHITTMAN-HART SPECIAL MEETING

    The purpose of the special meeting of Whittman-Hart's stockholders is to
consider and vote upon proposals to:

    - approve the merger and the issuance of shares of common stock to the
      stockholders of USWeb/CKS pursuant to the merger;

    - approve the proposed amendment of the Whittman-Hart charter to increase
      the number of authorized common shares from 75,000,000 to 500,000,000;

    - approve the proposed amendment to the 1995 Whittman-Hart Incentive Stock
      Plan to increase the number of shares of common stock available for award
      under the plan from 24,000,000 to 48,000,000; and

    - transact any other business that may properly come before the meeting,
      including the approval of any adjournment or postponement of the meeting.

    The merger will occur only if the proposals to amend the charter and to
issue Whittman-Hart common stock in connection with the merger are approved.


THE WHITTMAN-HART BOARD OF DIRECTORS UNANIMOUSLY APPROVED THE MERGER AGREEMENT
AND THE MERGER, AND RECOMMENDS A VOTE "FOR" APPROVAL OF THE PROPOSALS.


PROXIES

    The Whittman-Hart proxy accompanying this joint proxy statement/prospectus
is being solicited on behalf of the Whittman-Hart board of directors for use at
the Whittman-Hart special meeting. You may vote in person at your meeting or by
proxy. We recommend you vote by proxy even if you plan to attend the meeting.
You can always change your vote at the meeting. Voting instructions are included

not make specific choices, your proxy will follow the board's recommendation and
vote your shares for the proposals and in its discretion as to any other
business that may properly come before the meeting.

DATE, TIME AND PLACE OF MEETING


    The Whittman-Hart special meeting will be held on Monday, February 28, 2000
at 10:00 a.m., local time, at The Whittman-Hart Institute for Strategic
Education, 320 North Elizabeth Street, Chicago, Illinois 60607.


RECORD DATE AND OUTSTANDING SHARES


    Only holders of record of Whittman-Hart common stock at the close of
business on January 25, 2000, the record date, are entitled to notice of and to
vote at the Whittman-Hart special meeting. At the close of business on the
Whittman-Hart record date, there were 62,146,544 shares of Whittman-Hart common
stock outstanding. Each holder of record of common stock on the Whittman-Hart
record date will be entitled to one vote on all matters to be voted upon at the
Whittman-Hart special meeting.

VOTE REQUIRED

    A quorum of stockholders is necessary to hold a valid meeting. The presence,
in person or by properly executed proxy, of the holders of a majority of the
outstanding shares of Whittman-Hart common stock is necessary to constitute a

quorum. A broker non-vote occurs when a broker is not permitted to vote on that
item without instructions from the beneficial owner of the shares and no
instruction is given. Approval of the proposal to amend the charter of the
company to increase the number of authorized shares requires the affirmative
vote of a majority of the shares of Whittman-Hart common stock outstanding on
the record date. Abstentions and broker non-votes have the same effect as voting
against amending the charter. Approval of the proposals to issue shares to
USWeb/CKS stockholders in connection with the merger and to increase the number
of authorized shares of common stock available for issuance under the
Whittman-Hart 1995 Incentive Stock Plan requires the affirmative vote of a
majority of the total votes cast at the meeting in person or by proxy.

    The completion of the merger is not contingent upon the approval of the
proposal to amend the stock plan.


    As of the record date for the special meeting, directors and executive
officers of Whittman-Hart held approximately 13,309,202 shares of Whittman-Hart
common stock. All directors and executive officers are expected to vote in favor
of the Whittman-Hart proposals.


    Robert F. Bernard, Whittman-Hart's chairman and chief executive officer, has
signed a stockholder agreement with USWeb/CKS, pursuant to which he has agreed
to vote the shares of Whittman-Hart common stock he beneficially owns,
representing approximately 21% of the total outstanding shares of Whittman-Hart
common stock, in favor of the Whittman-Hart proposals.

REVOCABILITY OF PROXIES

    You may revoke your proxy before it is voted by:

    - submitting a new proxy with a later date,

    - notifying your company's secretary in writing before or at the meeting
      that you have revoked your proxy, or

    - voting in person at the meeting.

    If you have instructed a broker to vote your shares, you must follow
directions received from your broker to change your vote.

                             APPROVAL OF THE MERGER

BACKGROUND OF THE MERGER

    In early November 1999, Robert Shaw, the Chief Executive Officer of
USWeb/CKS, had informal conversations with Robert F. Bernard, the Chairman and
Chief Executive Officer of Whittman-Hart, regarding their businesses and
potential cooperative ventures. These informal conversations led management of
USWeb/CKS and Whittman-Hart to consider a possible merger of the two companies
because of the strategic benefits foreseen by management of both entities.
Management of Whittman-Hart had discussions with its financial advisors
regarding a possible merger transaction.

    On November 12, 1999, Mr. Bernard and Bert Young, Chief Financial Officer of
Whittman-Hart, met with Mr. Shaw and Carolyn Aver, Chief Financial Officer of
USWeb/CKS, to discuss the potential for a business combination. At about this
time, officers of USWeb/CKS sought advice from Morgan Stanley & Co. Incorporated
regarding the advisability of a business combination with Whittman-Hart.

    On November 18, 1999, Whittman-Hart sent USWeb/CKS a proposed
confidentiality agreement, an information request list and a discussion outline
for a meeting to be held with senior management of the two companies and their
financial advisors. On November 26, 1999, a confidentiality agreement was signed
by each company.

    On November 18, 1999, the Whittman-Hart board of directors met to discuss a
possible merger with USWeb/CKS, to receive a briefing on the conversations that
had taken place to date and to consider the proposed terms of such a
transaction. At the conclusion of the meeting, Mr. Bernard was authorized to
continue exploring a possible business combination with USWeb/CKS.

    On November 30, 1999, the Whittman-Hart board of directors met to further
discuss a possible merger with USWeb/CKS. At this meeting, Credit Suisse First
Boston Corporation, financial advisor to Whittman-Hart, reviewed with the board
the financial aspects of the potential merger with USWeb/CKS. Katten Muchin
Zavis, counsel to Whittman-Hart, reviewed the directors' responsibilities
associated with considering a business combination.

    Beginning on December 1 and continuing through December 3, 1999, management
of USWeb/CKS and Whittman-Hart and their advisors met in Chicago to discuss the
potential combination of the two businesses. During this time, USWeb/CKS also
began its due diligence review of the Whittman-Hart business, which continued
through the week of December 6, 1999.

    On December 6, 1999, Mr. Shaw and Ms. Aver held a telephone conference call
with several members of the USWeb/CKS board of directors to discuss the proposed
merger with Whittman-Hart. Mr. Shaw and Ms. Aver explained the background of the
negotiations and reviewed the current status of the negotiations and the
proposed terms of the transaction. Representatives of Morgan Stanley, financial
advisor to USWeb/CKS, discussed the financial aspects of the transaction.
Representatives of Wilson Sonsini Goodrich & Rosati, counsel to USWeb/CKS,
reviewed responsibilities of the board of directors in considering the proposed
transaction. Over the next few days, officers of USWeb/CKS called directors who
were unable to participate in the December 6 conference call to review with
those members the topics discussed in the December 6 conference call. USWeb/CKS
officers also had conversations with individual directors to provide updated
information with respect to the proposed merger.

    During the week of December 6, 1999, Whittman-Hart's representatives
conducted a due diligence review of USWeb/CKS's business in Palo Alto,
California, while legal counsel for the parties negotiated the merger agreement.
On December 8, 1999, the Whittman-Hart board of directors held a telephonic
meeting to discuss the current status of the negotiations, due diligence and the
terms and structure of the merger.

    On December 11, 1999, the USWeb/CKS board of directors met to discuss a
possible merger with Whittman-Hart, to receive a briefing on the negotiations to
date and review the specific proposed

                                       35
<PAGE>
transaction terms. At this meeting, representatives of Wilson Sonsini
Goodrich & Rosati again reviewed responsibilities of the board of directors in
considering the proposed transaction. Representatives of Morgan Stanley made a
detailed financial presentation to the board relating to the transaction.
Mr. Bernard attended a portion of the meeting to present his view of the
opportunities and issues that would face the combined companies.

    On December 11, 1999, the Whittman-Hart board of directors held a telephonic
meeting with representatives of their financial advisors and legal counsel and
discussed the status of negotiations, due diligence review and the terms and
conditions of the merger as set forth in the drafts of the merger agreement
previously provided to the Whittman-Hart board of directors. At this meeting,
Credit Suisse First Boston made a financial presentation relating to the merger
and delivered its oral opinion, which was subsequently confirmed by delivery of
a written opinion, dated December 12, 1999, the date of the merger agreement, to
the effect that as of the date of the opinion and based upon the matters stated
in the opinion, the exchange ratio was fair, from a financial point of view, to
Whittman-Hart. Further, the board's outside counsel explained to the board its
fiduciary duties regarding the merger.

    On December 12, 1999, the Whittman-Hart board of directors held a telephonic
meeting, reviewed the proposed transactions and agreements, and approved the
merger agreement with an exchange ratio of 0.865. The USWeb/CKS board of
directors held a telephonic board meeting with their advisors and discussed the
terms and conditions of the merger as set forth in drafts of the merger
agreement previously provided to the USWeb/CKS board of directors. At such
meeting, representatives of Morgan Stanley delivered its oral opinion, which was
subsequently confirmed by delivery of a written opinion dated December 12, 1999,
the date of the merger agreement, as to the fairness from a financial point of
view of the exchange ratio to the USWeb/CKS stockholders. The merger agreement
was approved by the USWeb/ CKS board of directors. The USWeb/CKS board of
directors also reviewed existing agreements concerning the acceleration of
certain stock options held by Mr. Shaw and Ms. Aver. The USWeb/CKS board of
directors determined to effect such acceleration, contingent upon closing of the
merger.

    Negotiations regarding the merger agreement continued throughout the day and
evening of December 12, 1999 regarding the final points of the merger agreement,
and the merger agreement and related documents were executed late that evening.
A public announcement of the merger was made on December 13, 1999.

JOINT REASONS FOR THE MERGER

    USWeb/CKS is a leading provider of Internet professional services with an
emphasis on the "dot com" and Fortune 500 business-to-consumer marketplace and
offers strong strategy and creative capabilities. Whittman-Hart is a leading
provider of e-commerce solutions to middle market business-to-business clients
and offers strong technical capabilities through its technology consulting
business. The boards of directors of Whittman-Hart and USWeb/CKS independently
concluded that the proposed merger will afford the combined company with the
complementary strengths of the two individual companies. Each of the boards of
directors believes that the merger will create a number of strategic benefits
that will enable the combined company to take advantage of increased market
demand for a variety of Internet professional services. These anticipated
strategic benefits include the following:

    - the combined company will be able to provide comprehensive
      supplier-to-consumer digital solutions that neither of us could provide
      alone;

    - the combined company's 8,000 professionals will possess premium talent and
      comprehensive skills in the strategy, marketing and creative, and
      technology disciplines;

    - the combined company's higher market profile, greater financial strength
      and increased marketing capability should enable it to respond more
      quickly and effectively to the rapid innovation and change and increased
      competition and market demands that characterize our industry;

                                       36
<PAGE>
    - the combined company's expanded geographic reach, with more than
      70 offices worldwide, will enable it to provide local service to global
      clients;

    - the combined company's expanded scale, flexible delivery capabilities and
      breadth of service offerings should position it to take advantage of
      increased market demands for multiple digital services from a single
      provider;

    - the combined company's expanded scale and client base will create
      additional opportunities for strategic alliances; and

    - the combined company will have the opportunity to leverage an even
      stronger executive management team and have better resources to recruit
      additional talented personnel.

    Whittman-Hart and USWeb/CKS have each identified additional reasons for the
merger, as discussed below. It should be noted, however, that some or all of the
potential benefits of the merger may not be realized. See "Risk Factors"
beginning on page 22.

USWEB/CKS'S REASONS FOR THE MERGER

    In addition to the anticipated potential joint benefits described above,
USWeb/CKS's board of directors believes that the following are additional
reasons the merger will be beneficial to USWeb/CKS and for stockholders of
USWeb/CKS to vote "FOR" adoption of the merger agreement;

    - the merger is expected to enhance the opportunity to be the leading
      provider of Internet professional services;

    - the exchange ratio in the merger represented a 34.7% premium over the
      closing price for USWeb/ CKS common stock on December 10, 1999, the last
      trading day prior to the signing of the merger agreement, as well as 27.6%
      and 10.5% premiums over the average exchange ratios for the ten and thirty
      trading days ending on December 10, 1999, respectively;

    - USWeb/CKS's stockholders should benefit from owning part of a larger and
      financially stronger enterprise with greater geographic coverage and
      additional management talent;

    - USWeb/CKS will be able to leverage the robust multi-office infrastructure
      developed by Whittman-Hart; and

    - USWeb/CKS will be able to combine its employee training and development
      programs with Whittman-Hart's well-developed programs.

    In the course of deliberations, the USWeb/CKS board reviewed with USWeb/CKS
management and outside advisors a number of additional factors relevant to the
merger, including:

    - historical information concerning Whittman-Hart's and USWeb/CKS's
      respective businesses, financial performance and condition, operations,
      technology, management and competitive position, including public reports
      concerning results of operations during the most recent fiscal year and
      fiscal quarter for each company filed with the SEC;

    - USWeb/CKS management's view as to the financial condition, results of
      operations and businesses of Whittman-Hart and USWeb/CKS before and after
      giving effect to the merger based on management due diligence and publicly
      available earnings estimates;

    - current financial market conditions and historical market prices,
      volatility and trading information with respect to Whittman-Hart common
      stock and USWeb/CKS common stock;

    - the consideration to be received by USWeb/CKS stockholders in the merger
      and an analysis of the market value of the Whittman-Hart common stock to
      be issued in exchange for each share of USWeb/CKS common stock in light of
      comparable merger transactions;

                                       37
<PAGE>
    - the terms of the merger agreement, including the parties' representations,
      warranties and covenants, and the conditions to the parties' respective
      obligations;

    - USWeb/CKS management's view as to the prospects of USWeb/CKS as an
      independent company;

    - USWeb/CKS management's view as to the potential for other third parties to
      enter into strategic relationships with or to acquire USWeb/CKS;

    - the impact of the merger on USWeb/CKS's customers and employees;

    - reports from management, legal advisors and financial advisors as to the
      results of their due diligence investigation of Whittman-Hart; and

    - the financial presentations by USWeb/CKS management and Morgan Stanley, as
      well as Morgan Stanley's opinion, which was subsequently confirmed by
      delivery of a written opinion dated December 12, 1999, to the effect that
      as of the date of the opinion and based upon and subject to matters stated
      in the opinion, the exchange ratio was fair, from a financial point of
      view, to the stockholders of USWeb/CKS. A copy of the opinion is attached
      hereto as Annex B and stockholders are urged to review it carefully.

    USWeb's board of directors also considered the terms of the merger agreement
regarding
USWeb/CKS's rights to consider and negotiate other strategic transaction
proposals, as well as the possible effects of the provisions regarding
termination fees. In addition, USWeb/CKS's board of directors noted that the
merger is expected to be a tax-free transaction. USWeb/CKS's board of directors
also considered various alternatives to the merger, including remaining as an
independent company. USWeb/CKS's board of directors believed that these factors,
including the terms of the merger agreement, supported the board's
recommendation of the merger when viewed together with the risks and potential
benefits of the merger. USWeb/CKS's board of directors also identified and
considered a variety of potentially negative factors in its deliberations
concerning the merger, including, but not limited to:

    - the risk that the potential benefits sought in the merger might not be
      fully realized;

    - the possibility that the merger might not be completed and the effect of
      public announcement of the merger on USWeb/CKS's sales and operating
      results, employee retention and recruiting efforts;

    - the substantial charges to be incurred in connection with the merger,
      including costs of integrating the businesses and transaction expenses
      arising from the merger;

    - the risk that despite the efforts of the combined company, key management
      and professional personnel might not remain employed by the combined
      company;

    - the difficulty of managing separate operations at different geographic
      locations, including multiple executive offices; and

    - the other risks described under "Risk Factors" beginning on page 22 of
      this joint proxy statement/ prospectus.

    USWeb/CKS's board of directors believed that these risks were outweighed by
the potential benefits of the merger. The foregoing discussion is not exhaustive
of all factors considered by USWeb/CKS's board of directors. Each member of
USWeb/CKS's board may have considered different factors, and USWeb/ CKS's board
evaluated these factors as a whole and did not quantify or otherwise assign
relative weights to factors considered.

WHITTMAN-HART'S REASONS FOR THE MERGER

    In addition to the anticipated joint benefits described above, the
Whittman-Hart board of directors believes that the following are additional
specific reasons the merger will be beneficial to Whittman-Hart

                                       38
<PAGE>
and recommends the stockholders of Whittman-Hart vote "FOR" approval of the
merger and related proposals:

    - the merger will accelerate the realization of our growth strategy,
      including geographic expansion and a broader range of service offerings;

      development goals more quickly and efficiently;

    - the merger will enable us to offer existing and new clients increased
      depth in strategy, consulting, marketing and creative services; and

    - the merger will allow employees to develop expertise in multiple
      disciplines and serve a broader group of clients in more diverse
      locations.

    In addition to the factors set forth above, in the course of its meetings,
the Whittman-Hart board of directors reviewed and considered a wide variety of
information relevant to the merger including:

    - information concerning Whittman-Hart's and USWeb/CKS's businesses,
      historical financial performance and condition, operations, customers,
      competitive positions, prospects and management;

    - Whittman-Hart's management's view as to the financial condition, results
      of operations and business and financial potential of Whittman-Hart and
      USWeb/CKS before and after giving effect to the merger, based on
      management's due diligence and publicly available earnings estimates;

    - current financial market conditions and historical market prices,
      volatility and trading information with respect to the Whittman-Hart
      common stock and USWeb/CKS common stock;

    - the consideration to be paid to the USWeb/CKS stockholders in the merger

      warranties and covenants, and the conditions to their respective
      obligations;

    - reports from management, legal advisors and financial advisors as to the
      results of their due diligence investigation of USWeb/CKS;

    - the potential impact of the merger on customers and employees of
    Whittman-Hart and
     USWeb/CKS; and

    - the financial presentation by Whittman-Hart management and Credit Suisse
      First Boston, as well as Credit Suisse First Boston's oral opinion, which
      was subsequently confirmed by delivery of a written opinion dated
      December 12, 1999, the date of the merger agreement, to the effect that as
      of the date of the opinion and based upon and subject to matters stated in
      the opinion, the exchange ratio was fair, from a financial point of view,
      to Whittman-Hart. A copy of the opinion is attached hereto as Annex C and
      stockholders are urged to read it carefully in its entirety.

    Whittman-Hart's board of directors also considered the terms of the merger
agreement regarding Whittman-Hart's rights to consider and negotiate other
strategic transaction proposals, as well as the possible effects of the
provisions regarding termination fees. In addition, Whittman-Hart's board of
directors noted that the merger is expected to be a tax-free transaction.
Whittman-Hart's board of directors believed that these factors, including the
terms of the merger agreement, supported the board's recommendation of the
merger when viewed together with the risks and potential benefits of the merger.
Whittman-Hart's board of directors also identified and considered a variety of
potentially negative factors in its deliberations concerning the merger,
including, but not limited to:

    - the risk that the potential benefits sought in the merger might not be
      fully realized,

                                       39
<PAGE>
    - the possibility that the merger might not be completed and the effect of
      public announcement of the merger on Whittman-Hart's sales and operating
      results, employee retention and recruiting efforts,

    - the substantial charges to be incurred in connection with the merger,
      including costs of integrating the businesses and transaction expenses
      arising from the merger,

    - the risk that despite the efforts of the combined company, key management
      and professional personnel might not remain employed by the combined
      company,

    - the difficulty of managing separate operations at different geographic
      locations, including multiple executive offices; and

    - the other risks described under "Risk Factors" beginning on page 22 of
      this joint proxy statement/ prospectus.

    Whittman-Hart's board of directors believed that these risks were outweighed
by the potential benefits of the merger.

    The foregoing discussion of the factors considered by the Whittman-Hart
board of directors is not intended to be exhaustive but is intended to summarize
the material factors considered by the Whittman-Hart board of directors. In view
of the complexity and variety of factors considered by the Whittman-Hart board
of directors, the Whittman-Hart board of directors did not consider it practical
to quantify or otherwise attempt to assign any relative or specific weights to
the specific factors considered, and individual directors may have given
differing weights to different factors.

    WHITTMAN-HART.  The Whittman-Hart board believes that the merger is

Hart charter amendment and the increase in the number of shares of Whittman-Hart

selected Morgan Stanley to act as USWeb/CKS's financial advisor based on Morgan
Stanley's qualifications, expertise and reputation and its knowledge of the
business and affairs of USWeb/CKS. At the meeting of the USWeb/CKS board of

<PAGE>
aspect of the merger and does not constitute a recommendation to any holder of
USWeb/CKS common stock as to how to vote at the USWeb/CKS special meeting. The
summary of the opinion of Morgan Stanley set forth in this document, while
materially complete, is qualified in its entirety by reference to the full text
of the opinion.

Stanley relied upon the assessment by the managements of USWeb/CKS and
Whittman-Hart of their ability to retain key employees of USWeb/CKS and

verification, the assessment by the managements of USWeb/CKS and Whittman-Hart
of:

    - the strategic and other benefits expected to result from the merger;

                                       41
<PAGE>

      Whittman-Hart; and

    - the validity of, and risks associated with, USWeb/CKS's and

      models.

    Morgan Stanley did not make any independent valuation or appraisal of the
assets or liabilities or technology of USWeb/CKS and Whittman-Hart, nor was it
furnished with any such appraisals. In addition, Morgan Stanley assumed that the
merger will be treated as a tax-free reorganization and/or exchange each
pursuant to the Internal Revenue Code of 1986 (as amended) and will be
consummated in accordance with the terms set forth in the draft of the merger
agreement, dated December 12, 1999. Morgan Stanley's opinion is necessarily
based on financial, economic, market and other conditions as in effect on, and
the information made available to Morgan Stanley as of, the date of its opinion.

    For this analysis, Morgan Stanley examined median estimates from securities
research analysts, where appropriate. The following table presents, as of
December 10, 1999, the following statistics:

    - the ratio of price to calendar year 2000 estimated earnings per share,
      commonly known as EPS; and

                                       42

    - the ratio of aggregate value, defined as market capitalization plus total
      debt less cash and cash equivalents to calendar year 2000 revenue.

</TABLE>

The analyses reflected in the table above show that as of December 10, 1999:

    - USWeb/CKS's common stock price was 74 times estimated calendar year 2000
      EPS, as compared to the comparable ratios for Whittman-Hart and the median
      of the companies in the High End/High Growth IT Services Index of 109 and
      237, respectively; and

    - USWeb/CKS's aggregate value was 7 times estimated calendar year 2000
      revenue, as compared to the comparable ratios for Whittman-Hart and the
      median of the companies in the High End/High Growth IT Services Index of 9
      and 17, respectively.

    No company utilized in the peer group comparison analysis is identical to
USWeb/CKS or Whittman-Hart. In evaluating the peer groups, Morgan Stanley made
judgments and assumptions with regard to industry performance, general business,
economic, market and financial conditions and other matters, many of which are
beyond the control of USWeb/CKS and Whittman-Hart, such as the impact of
competition on the businesses of USWeb/CKS and Whittman-Hart and the industry
generally, industry growth and the absence of any adverse material change in the
financial condition and prospects of USWeb/ CKS and Whittman-Hart or the
industry or in the financial markets in general. Mathematical analysis (such as
determining the average or median) is not in itself a meaningful method of using
peer group data.

    SECURITIES RESEARCH ANALYSTS' PRICE TARGETS.  Morgan Stanley reviewed and
analyzed future public market trading price targets for USWeb/CKS common stock
and Whittman-Hart common stock prepared and published by securities research
analysts during the period from October 26, 1999 to December 1, 1999, for
USWeb/CKS and from July 27, 1999 to December 1, 1999, for Whittman-Hart. These
targets reflect each analyst's estimate of the future public market trading
price of USWeb/CKS and Whittman-Hart common stock at the end of the particular
time period considered for each estimate. The range of price targets are set
forth below:

</TABLE>

    Morgan Stanley noted that the exchange ratio reflected a 26% and 41% premium
to the ratio of the average and median price targets for USWeb/CKS and
Whittman-Hart, respectively.

    Morgan Stanley noted that the public market trading price targets published
by the securities research analysts do not necessarily reflect current market
trading prices for USWeb/CKS common stock and

                                       43
<PAGE>
Whittman-Hart common stock and that these estimates are subject to
uncertainties, including the future financial performance of USWeb/CKS and
Whittman-Hart and future financial market conditions.

    EXCHANGE RATIO ANALYSIS.  Morgan Stanley reviewed the ratios of the closing
prices of USWeb/CKS common stock divided by the corresponding prices of
Whittman-Hart common stock over various periods during the twelve month period
ending December 10, 1999. Morgan Stanley examined the premium or discount
represented by the exchange ratio over the average daily exchange ratios over
various periods.

</TABLE>

Morgan Stanley noted that the exchange ratio was higher than the average
exchange ratio of the closing prices for all periods analyzed over the last
120 days. Morgan Stanley also noted that the exchange ratio represented an
approximate 35% premium to the closing price as of December 10, 1999.

    RELATIVE CONTRIBUTION ANALYSIS.  Morgan Stanley analyzed the pro forma
financial contribution of USWeb/CKS and Whittman-Hart to the combined company
assuming consummation of the merger and based on revenue and earnings estimates
from securities research analysts. Morgan Stanley calculated the implied
ownership of the combined company based on these financial contributions and
based on each company's capital structure, including certain shares which may be
issued in the future under existing contracts. The analysis showed, among other
things, the following:

<PAGE>
Morgan Stanley noted that the 56.8% ownership implied by the exchange ratio was
a premium to the ownership implied by each company's projected 1999 earnings and
was lower than the ownership implied by the projected earnings for calendar year
2000 and 2001.

    PRO FORMA MERGER ANALYSIS.  Morgan Stanley analyzed the pro forma impact of
the merger on the combined company's projected earnings per share for calendar
year 2000 both (i) before goodwill and non-cash compensation charges ("EBG") and
(ii) before depreciation, amortization and non-cash compensation charges
("EBDA"). Such analysis was based on earnings projections by securities research
analysts for USWeb/CKS and Whittman-Hart.

    - Morgan Stanley observed that the merger would result in earnings per share
      accretion for Whittman-Hart, prior to giving effect to any synergies, of
      approximately 6% for calendar year 2000 on an EBG and EBDA basis.

    - Morgan Stanley observed that the merger would result in earnings per share
      dilution for USWeb/ CKS, prior to giving effect to any synergies, of
      approximately 3% and 4% for calendar year 2000, respectively, based on an
      EBG and EBDA basis.

    The preparation of a fairness opinion is a complex process not necessarily
susceptible to partial analysis or summary description. In arriving at its
opinion, Morgan Stanley considered the results of all of its analyses as a whole
and did not attribute any particular weight to any analysis or factor considered
by it. Furthermore, Morgan Stanley believes that selecting any portion of its
analyses, without considering all analyses, would create an incomplete view of
the process underlying its opinion. In addition, Morgan Stanley may have given
various analyses and factors more or less weight than other analyses and
factors, and may have deemed various assumptions more or less probable than
other assumptions, so that the ranges of valuations resulting from any
particular analysis described above should not be taken to be Morgan Stanley's
view of the actual value of USWeb/CKS or Whittman-Hart. In performing its
analyses, Morgan Stanley made numerous assumptions with respect to industry
performance, general business and economic conditions and other matters, many of
which are beyond the control of USWeb/CKS or Whittman-Hart. Any estimates
contained in Morgan Stanley's analyses are not necessarily indicative of future
results or actual values, which may be significantly more or less favorable than
those suggested by such estimates.

    The analyses performed were prepared solely as part of Morgan Stanley's
analysis of the fairness of the exchange ratio pursuant to the merger agreement
from a financial point of view to the holders of common stock of USWeb/CKS and
were conducted in connection with the delivery of the Morgan Stanley opinion.
The analyses do not purport to be appraisals or to reflect the prices at which
the USWeb/CKS common stock or Whittman-Hart common stock might actually be sold.

    The exchange ratio pursuant to the merger agreement was determined through
arm's-length negotiations between USWeb/CKS and Whittman-Hart and was approved
by the USWeb/CKS board of directors. Morgan Stanley provided advice to USWeb/CKS
during such negotiations; however, Morgan Stanley did not recommend any specific
exchange ratio to USWeb/CKS or that any specific exchange ratio constituted the
only appropriate exchange ratio for the merger.

    In addition, Morgan Stanley's opinion and presentation to the USWeb/CKS
board of directors was one of many factors taken into consideration by
USWeb/CKS's board of directors in making its decision to approve the merger.
Consequently, Morgan Stanley's analyses as described above should not be viewed
as determinative of the opinion of the USWeb/CKS board of directors with respect
to the exchange ratio or of whether the USWeb/CKS board of directors would have
been willing to agree to a different exchange ratio.

    The USWeb/CKS board of directors retained Morgan Stanley based upon Morgan
Stanley's qualifications, experience and expertise. Morgan Stanley is an
internationally recognized investment banking and advisory firm. Morgan Stanley,
as part of its investment banking business, is continuously engaged in the

                                       45
<PAGE>
valuation of businesses and securities in connection with mergers and
acquisitions, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for corporate, estate and other purposes. In the ordinary course of
Morgan Stanley's trading and brokerage activities, Morgan Stanley or its
affiliates may at any time hold long or short positions, may trade or otherwise
effect transactions, for its own account or for the account of customers in the
securities of USWeb/CKS, Whittman-Hart or any other parties involved in the
transaction.

    Under the engagement letter, Morgan Stanley will receive a customary fee for
providing financial advisory services and a financial fairness opinion in
connection with the merger. Morgan Stanley will also be reimbursed for
out-of-pocket expenses. In addition, USWeb/CKS has also agreed to indemnify
Morgan Stanley and its affiliates, their respective directors, officers, agents
and employees and each person, if any, controlling Morgan Stanley or any of its
affiliates against certain liabilities and expenses, including certain
liabilities under the federal securities laws, arising out of Morgan Stanley's
engagement.

OPINION OF CREDIT SUISSE FIRST BOSTON CORPORATION, FINANCIAL ADVISOR TO
  WHITTMAN-HART

    Credit Suisse First Boston has acted as Whittman-Hart's financial advisor in
connection with the merger. Whittman-Hart selected Credit Suisse First Boston
based on Credit Suisse First Boston's experience, expertise and reputation, and
familiarity with Whittman-Hart's business. Credit Suisse First Boston is an
internationally recognized investment banking firm and is regularly engaged in
the valuation of businesses and securities in connection with mergers and
acquisitions, leveraged buyouts, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for corporate and other purposes.

    In connection with Credit Suisse First Boston's engagement, Whittman-Hart
requested that Credit Suisse First Boston evaluate the fairness, from a
financial point of view, to Whittman-Hart of the exchange ratio provided for in
the merger agreement. On December 11, 1999, at a meeting of the Whittman-Hart
board of directors held to evaluate the merger, Credit Suisse First Boston
rendered to the Whittman-Hart board of directors an oral opinion, which opinion
was confirmed by delivery of a written opinion dated December 12, 1999, the date
of the merger agreement, to the effect that, as of the date of the opinion and
based upon and subject to the matters described in the opinion, the exchange
ratio was fair, from a financial point of view, to Whittman-Hart.

    The full text of Credit Suisse First Boston's written opinion dated
December 12, 1999 to the Whittman-Hart board of directors, which sets forth the
procedures followed, assumptions made, matters considered and limitations on the
review undertaken, is attached as Annex C and is incorporated into this document
by reference. Holders of Whittman-Hart common stock are urged to, and should,
read this opinion carefully and in its entirety. Credit Suisse First Boston's
opinion is addressed to the Whittman-Hart board of directors and relates only to
the fairness of the exchange ratio from a financial point of view, does not
address any other aspect of the proposed merger or any related transaction and
does not constitute a recommendation to any stockholder as to any matter
relating to the merger. The summary of Credit Suisse First Boston's opinion in
this document is qualified in its entirety by reference to the full text of the
opinion.

    In arriving at its opinion, Credit Suisse First Boston reviewed the merger
agreement, as well as publicly available business and financial information
relating to Whittman-Hart and USWeb/CKS. Credit Suisse First Boston also
reviewed other information relating to Whittman-Hart and USWeb/CKS, provided to
or discussed with Credit Suisse First Boston by Whittman-Hart and USWeb/CKS, and
met with the managements of Whittman-Hart and USWeb/CKS to discuss the
businesses and prospects of Whittman-Hart and USWeb/CKS, including the ability
to integrate the businesses of Whittman-Hart and USWeb/ CKS.

    Credit Suisse First Boston also considered financial and stock market data
of Whittman-Hart and USWeb/CKS and compared those data with similar data for
other publicly held companies in businesses it

                                       46
<PAGE>
deemed similar to those of Whittman-Hart and USWeb/CKS and considered, to the
extent publicly available, the financial terms of other business combinations
and other transactions which have recently been effected. Credit Suisse First
Boston also considered other information, financial studies, analyses and
investigations and financial, economic and market criteria that it deemed
relevant.

    In connection with its review, Credit Suisse First Boston did not assume any
responsibility for independent verification of any of the information that was
provided to or otherwise reviewed by it and relied on that information being
complete and accurate in all material respects. With respect to financial
information forecasts, Credit Suisse First Boston was advised, and assumed, that
this information represents reasonable estimates and judgments as to the future
financial performance of Whittman-Hart and USWeb/CKS. The board of directors of
Whittman-Hart informed Credit Suisse First Boston and Credit Suisse First Boston
assumed that the merger will be treated as a tax-free reorganization for federal
income tax purposes.

    Credit Suisse First Boston was not requested to make, and did not make, an
independent evaluation or appraisal of the assets or liabilities, contingent or
otherwise, of Whittman-Hart or USWeb/CKS, and was not furnished with any
evaluations or appraisals. Credit Suisse First Boston's opinion was necessarily
based on information available to, and financial, economic, market and other
conditions as they existed and could be evaluated by, Credit Suisse First Boston
on the date of its opinion. Credit Suisse First Boston did not express any
opinion as to the actual value of the Whittman-Hart common stock when issued in
the merger or the prices at which the Whittman-Hart common stock will trade
after the merger. No other limitations were imposed on Credit Suisse First
Boston with respect to the investigations made or procedures followed in
rendering its opinion.

    In preparing its opinion to the Whittman-Hart board of directors, Credit
Suisse First Boston performed a variety of financial and comparative analyses,
including those described below. The summary of Credit Suisse First Boston's
analyses described below is not a complete description of the analyses
underlying Credit Suisse First Boston's opinion. The preparation of a fairness
opinion is a complex analytical process involving various determinations as to
the most appropriate and relevant methods of financial analyses and the
application of those methods to the particular circumstances and, therefore, a
fairness opinion is not readily susceptible to partial analysis or summary
description. In arriving at its opinion, Credit Suisse First Boston made
qualitative judgments as to the significance and relevance of each analysis and
factor that it considered. Accordingly, Credit Suisse First Boston believes that
its analyses must be considered as a whole and that selecting portions of its
analyses and factors or focusing on information presented in tabular format,
without considering all analyses and factors or the narrative description of the
analyses, could create a misleading or incomplete view of the processes
underlying its analyses and opinion.

    In its analyses, Credit Suisse First Boston considered industry performance,
regulatory, general business, economic, market and financial conditions and
other matters, many of which are beyond the control of Whittman-Hart and
USWeb/CKS. No company, transaction or business used in Credit Suisse First
Boston's analyses as a comparison is identical to Whittman-Hart or USWeb/CKS or
the proposed merger, and an evaluation of the results of those analyses is not
entirely mathematical. Rather, the analyses involve complex considerations and
judgments concerning financial and operating characteristics and other factors
that could affect the acquisition, public trading or other values of the
companies, business segments or transactions being analyzed. The estimates
contained in Credit Suisse First Boston's analyses and the ranges of valuations
resulting from any particular analysis are not necessarily indicative of actual
values or predictive of future results or values, which may be significantly
more or less favorable than those suggested by the analyses. In addition,
analyses relating to the value of businesses or securities do not purport to be
appraisals or to reflect the prices at which businesses or securities actually
may be sold. Accordingly, Credit Suisse First Boston's analyses and estimates
are inherently subject to substantial uncertainty.

                                       47
<PAGE>
    Credit Suisse First Boston's opinion and financial analyses were not the
only factors considered by the Whittman-Hart board of directors in its
evaluation of the proposed merger and should not be viewed as determinative of
the views of the Whittman-Hart board of directors or management with respect to
the merger or the exchange ratio.

    The following is a summary of the material financial analyses performed by
Credit Suisse First Boston in connection with the preparation of its opinion and
reviewed with the Whittman-Hart board of directors at a meeting of the board of
directors held on December 11, 1999. The financial analyses summarized below
include information presented in tabular format. In order to fully understand
Credit Suisse First Boston's financial analyses, the tables must be read
together with the text of each summary. The tables alone do not constitute a
complete description of the financial analyses. Considering the data set forth
in the tables below without considering the full narrative description of the
financial analyses, including the methodologies and assumptions underlying the
analyses, could create a misleading or incomplete view of Credit Suisse First
Boston's financial analyses.

    SELECTED COMPANIES ANALYSIS.  Credit Suisse First Boston compared financial,
operating and stock market data of USWeb/CKS to corresponding data of the
following publicly traded companies in the information technology services
industry:

    - Scient Corporation

    - Sapient Corporation

    - Razorfish, Inc.

    - Rare Medium Group, Inc.

    - iXL Enterprises, Inc.

    - Viant Corporation

    - Proxicom, Inc.

    - AppNet, Inc.

    - Tanning Technology Corporation

    - U.S. Interactive, Inc.

    - Luminant Worldwide Corporation

    - Modem Media.Poppe Tyson, Inc.

    Credit Suisse First Boston reviewed, among other things, estimated calendar
year 2000 price-to-earnings and enterprise values, calculated as equity value,
plus debt, less cash, as a multiple of estimated calendar year 2000 revenues.
All multiples were based on closing stock prices on December 10, 1999. Estimated
financial data for the selected companies was based on publicly available
research analysts' estimates. This analysis indicated an implied exchange ratio
reference range of approximately 0.694x to 0.946x.

    None of the selected companies is identical to USWeb/CKS. Accordingly, an
analysis of the results of this selected companies analysis involves complex
considerations of the selected companies and other factors that could affect the
public trading value of USWeb/CKS and the selected companies.

    Credit Suisse First Boston compared enterprise values in the selected
transactions as multiples of, among other things, latest twelve months revenues
and earnings before interest and taxes, commonly known as "EBIT," and equity
values in the selected transactions as a multiple of latest twelve months cash
net income. All multiples were based on financial information available at the
time of the relevant transaction. Credit Suisse First Boston then applied a
range of selected multiples for the selected transactions of latest twelve
months revenues, EBIT and cash net income, to corresponding financial data of
USWeb/CKS. This analysis indicated an implied exchange ratio reference range of
approximately 0.631x to 0.883x.

    No company or transaction used in the selected transactions analysis is
identical to Whittman-Hart, USWeb/CKS or the proposed merger. Accordingly, an
analysis of the results of this analysis involves complex considerations of the
companies involved and the transactions and other factors that could affect the
acquisition value of the companies and USWeb/CKS.

    TERMINAL VALUE ANALYSIS.  Credit Suisse First Boston estimated the present
value of USWeb/CKS's future stock price based upon estimated 2001 earnings per
share, commonly referred to as "EPS," for USWeb/CKS, which was derived by
applying the I/B/E/S long-term EPS growth rate for USWeb/CKS of 50% to estimated
2000 EPS for USWeb/CKS based upon publicly available research analysts'
estimates. Applying a range of multiples of 60.0x to 80.0x and discount rates
ranging from 14% to 18%, this analysis indicated an implied exchange ratio range
of approximately 0.765x to 1.056x.

    RELATIVE CONTRIBUTION ANALYSIS.  Credit Suisse First Boston performed a
contribution analysis comparing the relative contributions of Whittman-Hart and
USWeb/CKS to estimated calendar year 2000 revenues, gross profit, operating
income and net income of the combined company. This analysis yielded, after
adjustment to reflect net debt balances, among other things, an implied exchange
ratio reference range of approximately 0.938x to 1.346x, as indicated in the
following table:

    HISTORICAL STOCK PRICE ANALYSIS.  Credit Suisse First Boston performed an
exchange ratio analysis comparing the average exchange ratios implied by the
daily closing stock prices for Whittman-Hart and USWeb/CKS on December 10, 1999

    PRO FORMA EARNINGS IMPACT ANALYSIS.  Credit Suisse First Boston analyzed the
potential pro forma effect of the merger on Whittman-Hart's estimated cash EPS
for calendar year 2000. Based on the exchange ratio in the merger of 0.865x,
this analysis indicated that the proposed merger would be accretive to
Whittman-Hart's estimated cash EPS in calendar year 2000, excluding goodwill
amortization and other non-cash charges currently excluded from USWeb/CKS's
earnings. The actual results achieved by the combined company may vary from
projected results and the variations may be material.

    OTHER FACTORS.  In the course of preparing its opinion, Credit Suisse First
Boston also reviewed and considered other information and data, including:

    - Whittman-Hart's historical and projected financial information;

    - the common stock price performance of Whittman-Hart and USWeb/CKS relative
      to selected information technology services companies and Nasdaq; and

    - publicly available research analyst coverage of USWeb/CKS.

    MISCELLANEOUS.  Whittman-Hart has agreed to pay Credit Suisse First Boston
for its financial advisory services a customary fee. Whittman-Hart also has
agreed to reimburse Credit Suisse First Boston for its out-of-pocket expenses,
including fees and expenses of legal counsel and any other advisor retained by
Credit Suisse First Boston, and to indemnify Credit Suisse First Boston and
related parties against liabilities, including liabilities under the federal
securities laws, arising out of its engagement. In the ordinary course of
business, Credit Suisse First Boston and its affiliates may actively trade the
securities of both Whittman-Hart and USWeb/CKS for their own accounts and for
the accounts of customers and, accordingly, may at any time hold long or short
positions in such securities.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

    When considering the recommendation of USWeb/CKS's board of directors, you
should be aware that some USWeb/CKS directors and officers have interests in the
merger that are different from, or are in addition to, yours.


    In particular, Robert Shaw's employment agreement, dated as of November 1,
1998, and amended as of December 12, 1999, entitles him to acceleration of a
number of his unexercisable options to purchase shares of common stock of
USWeb/CKS upon the closing of the merger, based on his duration of service with
USWeb/CKS. Mr. Shaw's employment agreement also entitles him to receive payments
of up to $5 million to pay excise taxes imposed upon such accelerated options by
the Internal Revenue Code. Assuming the merger were to close March 1, 2000, the
number of shares of USWeb/CKS common stock subject to unvested options held by
Mr. Shaw that would vest upon completion of the merger is 375,000. Further, so
long as Mr. Shaw continues to serve as an employee, officer or director of the
combined company, he will continue to vest in his unexercisable options.



    Additionally, the USWeb/CKS board of directors determined to accelerate all
of Carolyn Aver's unvested stock options upon the closing of the merger.
Assuming the merger were to close March 1, 2000, the number of shares of
USWeb/CKS common stock subject to unvested options held by Ms. Aver that would
vest upon completion of the merger is 201,875.


    Some other officers of USWeb/CKS have provisions in their employment
agreements or arrangements that could accelerate their unvested options upon a
change of control of USWeb/CKS and in some cases, in combination with a
termination of, or a major change in, their employment with the combined
company. In some cases, it is not clear whether the merger constitutes a change
of control under the terms of their employment agreements or arrangements. The
overwhelming majority of other employees of USWeb/CKS are not entitled to
acceleration of unvested options upon the consummation of the merger, and
accordingly, upon termination of their employment, could lose the right to any
unvested options held by them. Options held by continuing employees will be
assumed by the combined company.


    As of the USWeb/CKS record date, directors and executive officers of
USWeb/CKS and their affiliates beneficially owned approximately 3% of the
outstanding shares of USWeb/CKS common stock.



    MMG LLC, a Cayman Islands limited liability company, owns approximately 7.6%
of the outstanding shares of USWeb/CKS. Each of the three members of the board
of directors of MMG are employees of USWeb/CKS.


    According to the terms of the merger agreement, Robert Shaw and three other
members of the board of directors of USWeb/CKS will join the combined company's
board of directors following the merger. Mr. Shaw will be Chairman of the board
of directors of the combined company. Robert Clarkson, the Chief Operating
Officer of USWeb/CKS, will be the Chief Operating Officer of the combined
company. In addition, these and other executive officers of USWeb/CKS are in the
process of negotiating the terms of their employment with the combined company
subject to completion of the merger. These terms are expected to be consistent
with usual and customary business practice.

    Whittman-Hart will indemnify present and former directors and officers of
USWeb/CKS against all claims arising out of actions and omissions occurring on
or prior to the effective time of the merger to the fullest extent permitted by
law, subject to certain limitations. Whittman-Hart has also agreed to maintain
for six years, subject to certain cost limitations, a policy of directors' and
officers' liability insurance with respect to matters occurring on or before the
effective time of the merger for the benefit of USWeb/CKS's directors and
officers.

ACCOUNTING TREATMENT

    The merger will be accounted for under the purchase method of accounting
under which the total consideration paid in the merger will be allocated to the
tangible and identifiable intangible assets acquired

                                       51
<PAGE>
and liabilities assumed of USWeb/CKS on the basis of their estimated fair values
on the acquisition date. The excess of purchase price over tangible and
identifiable intangible assets acquired and liabilities assumed will be recorded
as goodwill.

REGULATORY MATTERS


    ANTITRUST--Whittman-Hart and USWeb/CKS have filed the required pre-merger
Notification and Report Forms pursuant to U.S. antitrust laws. In connection
with the merger, the Federal Trade Commission or the Antitrust Division of the
U.S. Department of Justice could take such action under the antitrust laws as
either deems necessary or desirable in the public interest, including seeking to
enjoin consummation of the merger or seeking to cause divestiture of significant
assets of Whittman-Hart or USWeb/CKS or their subsidiaries. It is possible that
a challenge to the merger on antitrust grounds will be made, and we cannot
accurately predict the result of such challenge. Consummation of the merger is
conditioned upon, among other things, the expiration or termination of the
waiting period applicable to the consummation of the merger under U.S. or
foreign antitrust laws and the absence of any temporary restraining order,
preliminary or permanent injunction, or other order issued by any federal or
state court in the United States that prevents the consummation of the merger.


    SECURITIES LAWS--USWeb/CKS and Whittman-Hart must comply with the federal
securities laws and applicable securities laws of various states.

RIGHTS OF DISSENTING USWEB/CKS AND WHITTMAN-HART STOCKHOLDERS

    Neither USWeb/CKS nor stockholders are entitled to exercise dissenters' or
appraisal rights as a result of the merger or to demand payment for their shares
under Delaware law.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

    The following discussion summarizes the material federal income tax
consequences of the merger that are generally applicable to holders of USWeb/CKS
common stock. This discussion is based on current existing provisions of the
Internal Revenue Code, existing and proposed U.S. Treasury Regulations
thereunder and current administrative rulings and court decisions, all of which
are subject to change. Any such change, which may or may not be retroactive,
could alter the tax consequences to Whittman-Hart, USWeb/CKS or the USWeb/CKS
stockholders.

    USWeb/CKS stockholders should be aware that this discussion does not deal
with all U.S. federal income tax considerations that may be relevant to
particular USWeb/CKS stockholders in light of their particular circumstances,
such as stockholders who are dealers in securities, banks, insurance companies
or tax-exempt organizations, who are subject to the alternative minimum tax
provisions of the Internal Revenue Code, who are non-United States persons, who
acquired their shares in connection with stock option or stock purchase plans or
in other compensatory transactions or who hold their shares as a hedge or as a
part of a hedging, straddle, conversion or other risk reduction transaction. In
addition, the following discussion does not address the tax consequences of the
merger under foreign, state or local tax laws or the tax consequences of
transactions effectuated prior to or after the merger (whether or not such
transactions are in connection with the merger).

    USWEB/CKS STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
SPECIFIC TAX CONSEQUENCES OF THE MERGER TO THEM IN THEIR PARTICULAR
CIRCUMSTANCES, INCLUDING THE APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN TAX
CONSEQUENCES.

    Neither Whittman-Hart nor USWeb/CKS has requested or will request a ruling
from the Internal Revenue Service regarding any of the U.S. federal income tax
consequences of the merger. As a condition to consummation of the merger, Wilson
Sonsini Goodrich & Rosati, Professional Corporation, counsel to USWeb/CKS, and
Katten Muchin Zavis, counsel to Whittman-Hart, will each render a tax opinion to

                                       52
<PAGE>
USWeb/CKS and Whittman-Hart, respectively, that the merger will constitute a
reorganization under Section 368(a) of the Internal Revenue Code provided,
however, that if either firm does not render such opinion, this condition shall
nonetheless be deemed to be satisfied with respect to such party if counsel to
the other party renders such opinion to such party. If either USWeb/CKS or
Whittman-Hart waives receipt of a tax opinion, the USWeb/CKS stockholders and
the Whittman-Hart stockholders will be notified and resolicited. Such tax
opinions are, and will be, based on certain assumptions and representations, and
will be subject to certain limitations. Moreover, such opinions will not be
binding on the IRS nor preclude the IRS or a court from adopting a contrary
position. The discussion below assumes that the merger will qualify as a
reorganization.

    Subject to the limitations and qualifications referred to herein, and as a
result of the merger qualifying as a reorganization, the following U.S. federal
income tax consequences will result:

    - no gain or loss will be recognized by the holders of USWeb/CKS common
      stock upon the receipt of Whittman-Hart common stock in exchange for
      USWeb/CKS common stock in the merger (except to the extent, if any, of
      cash received in lieu of fractional shares);

    - the aggregate tax basis of the Whittman-Hart common stock received by the
      USWeb/CKS public stockholders in the merger (including any fractional
      share of Whittman-Hart common stock not actually received) will be the
      same as the aggregate tax basis of USWeb/CKS common stock surrendered in
      exchange therefor;

    - the holding period of Whittman-Hart common stock received by each
      USWeb/CKS public stockholder in the merger will include the period for
      which the USWeb/CKS common stock exchanged therefor was considered to be
      held, provided that the USWeb/CKS common stock surrendered was held as a
      capital asset at the effective time of the merger; and

    - cash payments received by the USWeb/CKS public stockholders in lieu of a
      fractional share will be treated as if a fractional share of Whittman-Hart
      common stock was issued in the merger and then redeemed by Whittman-Hart.
      A USWeb/CKS public stockholder receiving such cash will recognize gain or
      loss upon such payment, measured by the difference (if any) between the
      amount of cash received and the basis of such fractional share. The gain
      or loss should be capital gain or loss provided that the USWeb/CKS common
      stock was held as a capital asset at the effective time of the merger.

    The tax opinions will be subject to certain assumptions and qualifications
and will be based on the accuracy of certain representations of Whittman-Hart,
the merger subsidiary and USWeb/CKS, including representations in certain
certificates delivered to counsel by the respective managements of Whittman-
Hart, the merger subsidiary and USWeb/CKS.

    A successful IRS challenge to the reorganization status of the merger could
result in significant adverse tax consequences to the USWeb/CKS stockholders. A
USWeb/CKS stockholder would recognize gain or loss on each share of USWeb/CKS
common stock surrendered equal to the difference between the basis of such share
and the fair market value, as of the effective time of the merger, of the
Whittman-Hart common stock received in exchange therefor. In such event, a
stockholder's aggregate basis in the Whittman-Hart common stock received would
equal its fair market value, and the stockholder's holding period for such stock
would begin the day after the effective time of the merger.

    Certain noncorporate USWeb/CKS stockholders may be subject to backup
withholding at a rate of 31% on cash payments received in lieu of a fractional
share of Whittman-Hart common stock. Backup withholding will not apply, however,
to a stockholder who furnishes a correct taxpayer identification number and
certifies that he, she or it is not subject to backup withholding on the
substitute Form W-9 included in the transmittal letter from the exchange agent,
who provides a certificate of foreign status on Form W-8, or who is otherwise
exempt from backup withholding. A stockholder who fails to provide the correct
taxpayer identification number on Form W-9 may be subject to a $50 penalty
imposed by the IRS.

                                       53
<PAGE>
    Each USWeb/CKS stockholder will be required to retain records and file with
such stockholder's U.S. federal income tax return a statement setting forth
certain facts relating to the merger.

USWEB/CKS VOTING AGREEMENTS

    Pursuant to the USWeb/CKS voting agreements, three stockholders of USWeb/CKS
who beneficially owned an aggregate of approximately 2% of the outstanding
shares of USWeb/CKS common stock as of December 31, 1999, have agreed that they
will vote their shares of USWeb/CKS common stock: (i) for approval of the merger
agreement and the merger, and (ii) against any action which is intended to
impede or interfere with the transactions contemplated by the merger agreement.
In addition, these stockholders have generally agreed not to transfer any
securities of USWeb/CKS owned by them except as contemplated by the merger
agreement. The form of the USWeb/CKS voting agreement is attached to this joint
proxy statement/prospectus as Annex D. The following USWeb/CKS stockholders have
signed USWeb/CKS voting agreements, in substantially the form of Annex D: Robert
Shaw, Chief Executive Officer of USWeb/CKS, Mark D. Kvamme, Chairman of the
Board of USWeb/CKS, and Robert Hoff, Director of USWeb/CKS.

WHITTMAN-HART VOTING AGREEMENT

    Pursuant to the Whittman-Hart voting agreement, Robert Bernard, Chairman of
the Board and Chief Executive Officer of Whittman-Hart, who beneficially owned
an aggregate of approximately 21% of the outstanding shares of Whittman-Hart
common stock as of December 31, 1999, has agreed that he will vote his shares of
Whittman-Hart common stock: (i) for approval of the merger agreement and the
merger, including the amendment to Whittman-Hart's charter; and (ii) against any
action which is intended to impede or interfere with the transactions
contemplated by the merger agreement. In addition, Mr. Bernard has agreed not to
transfer any securities of Whittman-Hart owned by him except as contemplated by
the merger agreement. The Whittman-Hart voting agreement is attached to this
joint proxy statement/ prospectus as Annex E.

USWEB/CKS AFFILIATE LETTERS; RESTRICTIONS ON SALES BY USWEB/CKS AFFILIATES

    USWeb/CKS has identified each of its affiliates, as that term is defined
under SEC rules. USWeb/CKS has agreed to use its reasonable efforts to obtain
written agreements from each USWeb/CKS affiliate stating that he or she will not
sell, pledge, transfer or otherwise dispose of shares of Whittman-Hart common
stock received in the merger, except in compliance with Rule 145 under the
Securities Act.

    The shares of Whittman-Hart common stock to be issued in connection with the
merger will be registered under the Securities Act of 1933 and will be freely
transferable under the Securities Act, except for shares of Whittman-Hart common
stock issued to any person who is deemed to be an affiliate of either party at
the time of the special meeting. Persons who may be deemed to be affiliates
include individuals or entities that control, are controlled by, or are under
common control of, either of the companies and may include some officers and
directors, as well as principal stockholders. Affiliates may not sell their
shares of Whittman-Hart common stock acquired in connection with the merger
except pursuant to:

    - an effective registration statement under the Securities Act covering the
      resale of those shares;

    - an exemption under paragraph (d) of Rule 145 under the Securities Act; or

    - any other applicable exemption under the Securities Act.

The registration statement in which this joint proxy statement/prospectus is
included does not cover the resale of shares of Whittman-Hart common stock to be
received by affiliates in the merger.

                              THE MERGER AGREEMENT

    The following summary of the merger agreement is qualified by reference to
the complete text of the merger agreement, which is incorporated by reference
and attached as Annex A.

STRUCTURE OF THE MERGER

    Under the merger agreement, a subsidiary of Whittman-Hart will merge with
and into USWeb/CKS, with USWeb/CKS continuing as the surviving corporation.

TIMING OF CLOSING

    The closing will occur on the second business day after the conditions set
forth in the merger agreement have been satisfied or waived. We expect that, as
promptly as practicable after the closing, we will file a certificate of merger
with the Secretary of State of the State of Delaware, at which time or at such
time thereafter as provided in the certificate of merger, the merger will become
effective.

CONSIDERATION TO BE RECEIVED IN THE MERGER

    The merger agreement provides that each share of USWeb/CKS common stock
outstanding immediately prior to the effective time of the merger will, at the
effective time of the merger, be converted into the right to receive 0.865 of a
share of Whittman-Hart common stock (other than shares held by Whittman-Hart or
its subsidiaries or by USWeb/CKS). The number of shares of Whittman-Hart common
stock to be received per share of USWeb/CKS common stock is referred to in this
joint proxy statement/prospectus as the "exchange ratio." Any shares of
USWeb/CKS common stock held by USWeb/CKS as treasury stock or owned by
Whittman-Hart or its subsidiaries will be canceled without any payment for those
shares and each issued and outstanding share of common stock of Whittman-Hart's
merger subsidiary will be converted automatically into for one share of common
stock of the surviving corporation.

CONVERSION OF USWEB/CKS OPTIONS AND WARRANTS

    The merger agreement provides that each outstanding and unexercised option
and warrant to purchase shares of USWeb/CKS common stock will be assumed by
Whittman-Hart and converted into an option or warrant to purchase shares of
Whittman-Hart common stock. The number of shares of Whittman-Hart common stock
to be subject to such new options and warrants will be determined by multiplying
the number of shares of USWeb/CKS common stock subject to the original option or
warrant by the exchange ratio and rounding down to the nearest full share, and
the exercise price with respect thereto will equal the exercise price under the
original option or warrant divided by the exchange ratio and rounded up to the
nearest tenth of a cent.

NO FRACTIONAL SHARES

    No fractional shares of Whittman-Hart common stock will be issued in
connection with the merger. In lieu of such fractional shares, any holder of
USWeb/CKS common stock will, upon surrender of such holder's stock
certificate(s) representing USWeb/CKS common stock to an exchange agent mutually
agreed upon by the parties, be paid in cash the dollar amount, without interest,
determined by multiplying such fraction by the closing price of a share of
Whittman-Hart common stock on the Nasdaq National Market on the trading day
immediately prior to the effective time of the merger.

CONVERSION OF USWEB/CKS COMMON STOCK; PROCEDURES FOR EXCHANGE OF CERTIFICATES

    Promptly after the effective time, the exchange agent will mail to the
registered holders of USWeb/CKS common stock (i) a letter of transmittal and
(ii) instructions for use in effecting the surrender of the USWeb/CKS stock
certificates in exchange for certificates representing shares of Whittman-Hart

                                       55
<PAGE>
common stock. Upon surrender of a USWeb/CKS stock certificate to the exchange
agent, together with a duly executed letter of transmittal and any other
required documents, the holder of such USWeb/CKS stock certificate will be
entitled to receive for each USWeb/CKS share, a certificate representing the
whole number of shares of Whittman-Hart common stock that such holder has the
right to receive. No fractional shares of Whittman-Hart common stock will be
issued in connection with the merger, and no certificates for any such
fractional shares will be issued.

    USWEB/CKS STOCKHOLDERS SHOULD NOT SURRENDER THEIR USWEB/CKS STOCK
CERTIFICATES FOR EXCHANGE UNTIL THEY RECEIVE A LETTER OF TRANSMITTAL FROM THE
EXCHANGE AGENT.

CERTAIN CONDITIONS

    CONDITIONS OF EACH PARTY'S OBLIGATIONS TO EFFECT THE MERGER.  The obligation
of each party to the merger agreement to consummate the merger is subject to the
following: (a) the merger agreement and the merger shall have received the
approval of the stockholders of USWeb/CKS, (b) the issuance of Whittman-Hart
common stock to the USWeb/CKS stockholders in connection with the merger shall
have received the approval of the stockholders of Whittman-Hart, (c) the
registration statement that includes this joint proxy statement/prospectus shall
not be the subject of any stop order suspending its effectiveness, (d) no
judgment, order, decree, statute, law, ordinance, rule or regulation, or other
legal restraint or prohibition preventing consummation of the merger shall be in
effect or pending, (e) any waiting period applicable to the merger under U.S. or
foreign antitrust laws and all applicable material foreign merger laws shall
have expired or been terminated, and (f) Whittman-Hart and USWeb/CKS shall have
received opinions as to certain tax matters related to the merger. The
conditions to a party's obligations to effect the merger may be waived by the
party entitled to assert the condition.

    CONDITIONS TO THE OBLIGATIONS OF USWEB/CKS.  The obligation of USWeb/CKS to
complete the merger is also subject to the following: (a) subject to certain

CERTAIN COVENANTS

    Each of Whittman-Hart and USWeb/CKS has undertaken certain covenants in the
merger agreement. The following summarizes the more significant of these
covenants.

    NO SOLICITATION.  USWeb/CKS and Whittman-Hart have agreed that they and
their subsidiaries and their directors, officers, affiliates and advisers will
not take action to solicit or encourage an offer for an alternative acquisition
transaction involving USWeb/CKS or Whittman-Hart of a nature defined in the
merger agreement.

    Restricted actions include engaging in any discussions with or furnishing
any information to a potential bidder, or knowingly taking any other action
designed to facilitate an alternative transaction. Whittman-Hart or USWeb/CKS,
as the case may be, is permitted to take these actions in response to an
unsolicited offer, however, if the board of Whittman-Hart or USWeb/CKS, as the
case may be, determines in good faith that such action is required by its
fiduciary duties and that the unsolicited offer is likely to result in a more
favorable transaction for its stockholders. In such event, the Whittman-Hart or
USWeb/CKS board, as the case may be, must inform the non-acting party of the
material terms of the unsolicited offer no less than 24 hours prior to
participation in any such discussions. Each of USWeb/CKS and Whittman-Hart must
keep the other reasonably informed of the status and any material change to the
terms of the unsolicited offer.

    USWEB/CKS BOARD'S COVENANT TO RECOMMEND.  The USWeb/CKS board has agreed to
recommend to USWeb/CKS's stockholders the approval and adoption of the merger
agreement and the merger. However, the USWeb/CKS board may withhold or modify
its recommendation if the USWeb/CKS Board determines in good faith, in
consultation with outside counsel, that such withdrawal or modification is
required by its fiduciary duties.

    WHITTMAN-HART BOARD'S COVENANT TO RECOMMEND.  The Whittman-Hart board has
agreed to recommend the approval of the merger agreement and the issuance of
shares of Whittman-Hart common stock in the merger to Whittman-Hart's
stockholders. However, the Whittman-Hart board may withhold or modify its
recommendation the issuance of shares to USWeb/CKS stockholders in the merger if
the Whittman-Hart board determines in good faith, in consultation with outside
counsel, that such withdrawal or modification is required by its fiduciary
duties.

    COVENANT TO HOLD STOCKHOLDER MEETINGS.  Whittman-Hart and USWeb/CKS have
agreed to submit the merger agreement and any related transactions to their
stockholders at the meetings even if their boards of directors no longer
recommend approval and adoption of the merger agreement and any related
transactions.

    CONDUCT OF BUSINESS OF WHITTMAN-HART AND USWEB/CKS.  Whittman-Hart and
USWeb/CKS are required to conduct their business in the ordinary course
consistent with past practice until the effective time of the merger and,
subject to certain exceptions, may not engage in certain material transactions
during this period.

    COOPERATION COVENANT.  Whittman-Hart and USWeb/CKS have agreed to cooperate
with each other to use their reasonable efforts to take all actions and do all
things necessary, proper or appropriate to complete the merger and the other
transactions contemplated by the merger agreement as soon as practicable.

    INDEMNIFICATION AND INSURANCE OF WHITTMAN-HART AND USWEB/CKS DIRECTORS AND
OFFICERS.  The merger agreement provides that after the effective time of the
merger:

    - Whittman-Hart will indemnify present and former directors and officers of
      USWeb/CKS against all claims arising out of actions or omissions occurring
      on or prior to the effective time to the fullest extent permitted by law,
      however, such indemnification shall be limited to the indemnification

                                       57
<PAGE>
      provided in the charter and by-laws of USWeb/CKS or the indemnification
      actually provided by USWeb/CKS as of the date of the merger agreement; and

    - Whittman-Hart will maintain in effect for at least six years the current
      policies of directors' and officers' liability insurance and fiduciary
      liability insurance maintained by USWeb/CKS, Whittman-Hart and their
      subsidiaries respectively (except that Whittman-Hart may substitute
      policies which are, in the aggregate, no less advantageous to the insured
      in any material respect) with respect to any claims arising from facts or
      events which occurred on or before the effective time of the merger,
      subject to certain cost limitations.

    FILING OF REGISTRATION STATEMENT ON FORM S-8.  Promptly following the
closing date, Whittman-Hart will file a Registration Statement on Form S-8 under
the Securities Act covering the shares of Whittman-Hart common stock issuable
with respect to options to purchase USWeb/CKS common stock assumed by
Whittman-Hart.

    CERTAIN OTHER COVENANTS.  The merger agreement contains other mutual
covenants of the parties that are typical for a transaction similar to the
merger.

TERMINATION

    Until the effective time, the merger agreement may be terminated by
USWeb/CKS and Whittman-Hart by mutual consent, or by either USWeb/CKS or
Whittman-Hart if:

    - the merger has not been consummated on or before May 31, 2000;

    - any judgment, order, decree, statute, law, ordinance, rule or regulation
      or other legal restraint shall be in effect and shall have become final or
      non-appealable;

    - the approval of either party's stockholders shall not have been obtained
      (however, a party may not use this provision to terminate if such failure
      was caused by a breach of certain covenants of such party); or

    - the other party has breached or failed to comply in any material respect
      with any of its obligations under the merger agreement or any
      representation or warranty made by the other party in the merger agreement
      is incorrect in any material respect, and such breaches, failures, or
      misrepresentations are not cured within 20 business days of notice.

The merger agreement may also be terminated by USWeb/CKS or Whittman-Hart if the
other party's board of directors withdraws or adversely modifies its approval or
recommendation of the merger or the merger agreement, or approves or recommends
any other acquisition proposal, or a tender offer or exchange offer for such
party's outstanding common stock is commenced and such party's board of
directors fails to oppose such offer or such party enters into discussions in
violation of the no solicitation covenant.

TERMINATION FEE

    The merger agreement obligates payment of a termination fee of $150 million
as follows:

    - if an acquisition proposal or the intention to make an acquisition
      proposal to either USWeb/CKS or Whittman-Hart shall have been made
      directly to the stockholders of such company, generally or otherwise
      publicly announced by such company or the person making the acquisition
      proposal, AND the acquisition proposal or intention is not irrevocably and
      publicly withdrawn prior to the vote of such company's stockholders at the
      duly held stockholders' meeting, and thereafter the merger agreement is
      terminated by either party due to (i) such company's stockholders not
      approving the merger or (ii) the stockholders' meeting not occurring prior
      to May 31, 2000 as a result of such acquisition proposal; PROVIDED,
      HOWEVER, that no termination fee will be payable to the company which was
      not subject to the acquisition proposal unless and until within twelve
      (12) months of such

                                       58
<PAGE>
      termination the company which was subject to the acquisition proposal or
      any of its subsidiaries enters into any acquisition agreement with respect
      to, or consummates any acquisition proposal, in which event the
      termination fee will be payable upon the first to occur of such events.
      Also, if either Whittman-Hart or USWeb/CKS consummates an acquisition
      proposal during the twelve (12) month period subsequent to such
      termination contemplated by this paragraph with the same person or an
      affiliate of the person that made and withdrew an acquisition proposal
      prior to such termination, such company will pay the termination fee; or

    - if USWeb/CKS or Whittman-Hart terminates the merger agreement because the
      other party's board of directors has withdrawn or adversely modified its
      recommendation of the merger or the merger agreement.

EXPENSES

    Each of Whittman-Hart and USWeb/CKS will bear its own costs and expenses
incurred in connection with the merger agreement and the transactions
contemplated thereby, except that (a) the combined company shall pay any
property or transfer taxes imposed on the combined company as a result of the
merger and (b) the printing of the registration statement that includes this
joint proxy statement/ prospectus will be shared equally by USWeb/CKS and
Whittman-Hart, and (c) the filing fees of the pre-merger notification and report
forms relating to the merger under U.S. or foreign antitrust laws will be shared
equally.

                         AMENDMENT TO THE WHITTMAN-HART
                          CERTIFICATE OF INCORPORATION

    The board of directors of Whittman-Hart has declared the advisability of and
approved, and is submitting for stockholder adoption, an amendment to
Whittman-Hart's Amended and Restated Certificate of Incorporation that increases
the authorized shares of common stock from 75,000,000 shares to
500,000,000 shares. The proposed amendment is as follows:

      "AUTHORIZED SHARES. The total number of shares of all classes of
      stock which the Corporation shall have authority to issue is five
      hundred three million (503,000,000) shares, consisting of five
      hundred million (500,000,000) shares of common stock, par value
      $.001 per share (the "Common Stock"), and three million (3,000,000)
      shares of Preferred Stock, par value $.001 per share (the "Preferred
      Stock")."


    Under Whittman-Hart's current Amended and Restated Certificate of
Incorporation, Whittman-Hart has the authority to issue 75,000,000 shares of
common stock and 3,000,000 shares of preferred stock. At the record date,
62,146,544 shares of common stock were issued and outstanding and no shares
of preferred stock were outstanding. Accordingly, as of such date, after taking
into account the shares reserved for issuance under Whittman-Hart's 1995
Incentive Stock Plan and upon the exercise of outstanding options issued by
Whittman-Hart, no shares of common stock remained available for issuance. As of
the record date, the issuance of Whittman-Hart common stock to USWeb/CKS
stockholders in the merger would require approximately 81,482,000 shares of
common stock, and significant additional shares will be issued by Whittman-Hart
in the future to satisfy option, warrant, bonus and earn-out obligations of
USWeb/CKS that will be assumed by Whittman-Hart in the merger.


    Although Whittman-Hart has no specific plans to use the additional
authorized shares of common stock other than as described above or pursuant to
the plan, the board of directors believes that an increase in the number of
authorized shares to the proposed level is advisable because, in addition to
allowing Whittman-Hart to issue shares of its common stock in and in connection
with the merger, it will provide Whittman-Hart with a reserve of shares and
needed flexibility in connection with possible future financing transactions,
acquisitions of other companies or business properties, stock splits, employee
benefit plans and other corporate purposes. Having such additional authorized
shares available for issuance in the future would allow the Whittman-Hart board
of directors to issue shares of Whittman-Hart common stock without the delay and
expense associated with seeking stockholder approval. Elimination of such delays
and expense occasioned by the necessity of obtaining stockholder approval will
better enable Whittman-Hart (or, after the merger, the combined company), among
other things, to engage in financing transactions and acquisitions as well as to
take advantage of changing market and financial conditions on a more competitive
basis as determined by Whittman-Hart's board (or, after the merger, the combined
company's board).

    The increase in authorized Whittman-Hart common stock will not have any
immediate effect on the rights of existing stockholders. To the extent that the
additional authorized shares are issued in the future, they will decrease the
existing stockholders' percentage equity ownership and, depending on the price
at which they are issued, could be dilutive to the existing stockholders.

    The increase in the authorized number of shares of Whittman-Hart common
stock could have an anti-takeover effect. Shares of authorized and unissued
Whittman-Hart common stock could (within the limits imposed by applicable law)
be issued in one or more transactions that would make a takeover of
Whittman-Hart more difficult, and therefore less likely. Any such issuance of
additional stock could have the effect of diluting the earnings per share and
book value per share of outstanding shares of Whittman-Hart common stock, and
such additional shares could be used to dilute the stock ownership or voting
rights of persons seeking to obtain control of Whittman-Hart. See "Risk
Factors--Risks Relating to the

Combined Company--The organizational documents of the combined company and
current Delaware law may deter potentially beneficial takeover attempts."


THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" APPROVAL OF THE AMENDMENT TO THE
AMENDED AND RESTATED CERTIFICATE OF INCORPORATION INCREASING THE NUMBER OF
SHARES OF COMMON STOCK AUTHORIZED FOR ISSUANCE FROM 75,000,000 TO 500,000,000.



            AMENDMENT TO THE WHITTMAN-HART 1995 INCENTIVE STOCK PLAN



    The Whittman-Hart 1995 Incentive Stock Plan, as approved and adopted by
stockholders, currently provides that 24,000,000 shares of Whittman-Hart common
stock are authorized for award thereunder. As of December 31, 1999,
Whittman-Hart had granted options to purchase 16,662,916 shares of Whittman-
Hart common stock under the plan. After taking cancellations and forfeitures
into account at December 31, 1999, 7,337,084 shares of Whittman-Hart common
stock remained available for future option grants. On completion of the merger,
the combined company will have approximately 8,000 employees. As a result of the
merger, the combined company will more directly compete within an employment
base for which stock options have historically represented a significant portion
of compensation. Because of these factors, the board believes that it is
necessary to increase the number of shares of Whittman-Hart common stock
authorized for issuance under the plan. Therefore, in December 1999, in
connection with its approval of the merger, Whittman-Hart's board of directors
approved an amendment to the plan that increased the number of shares of common
stock available for issuance under the plan from 24,000,000 shares to 48,000,000
shares. The Whittman-Hart board is seeking stockholder approval of the proposed
amendment to the plan to meet the requirements of the Nasdaq National Market and
the Internal Revenue Code.


    Whittman-Hart has historically utilized stock options as a part of its
overall compensation program for key employees, officers and directors. The
board of directors believes that it is in the best interests of Whittman-Hart to
have stock-based awards available for these individuals. The board of directors
believes that the proposed amendment, if approved by stockholders, will assist
Whittman-Hart in attracting, retaining, and motivating highly qualified
personnel.

    The following is a brief summary of certain provisions of the plan.

SUMMARY OF THE PLAN

    The purpose of the plan is to enable Whittman-Hart to provide officers and
employees of Whittman-Hart and its subsidiaries with performance-based equity
and monetary incentives, thereby attracting, retaining and rewarding such
persons and strengthening the mutuality of interest between such persons and
Whittman-Hart's stockholders.

    The maximum number of shares which currently may be awarded to any
participant in any year during the term of the plan is 100,000 shares. If there
is a lapse, cancellation, expiration or termination of any option prior to the
issuance of shares, or if shares are issued and thereafter are reacquired by
Whittman-Hart pursuant to rights reserved upon issuance thereof, those shares
may again be used for new awards under the plan.

                                       61
<PAGE>
    The plan is administered by the compensation committee of the board of
directors. Among the committee's powers are the authority to interpret the plan,
establish rules and regulations for its operation, select officers and other
employees of Whittman-Hart and its subsidiaries to receive awards, and determine
the form, amount and other terms and conditions of awards.

    Officers and employees of Whittman-Hart or any of its subsidiaries are
eligible to participate in the plan. The selection of participants is within the
discretion of the compensation committee. Approximately 3,900 employees and
non-employee directors were eligible to participate in the plan on December 31,
1999.

    The plan provides for the grant of any or all of the following types of
awards:

    - stock options, including incentive stock options and nonqualified stock
      options;

    - stock appreciation rights;

    - stock awards;

    - performance shares; and

    - performance units.

Awards may be granted singly, in combination, or in tandem as determined by the
compensation committee.


    Under the plan, the compensation committee may grant awards in the form of
incentive stock options or nonqualified stock options to purchase shares of
Whittman-Hart common stock. The compensation committee, with regard to each
stock option, determines the number of shares subject to the option, the manner
and time of the option's exercise and vesting, and the exercise price per share
of stock subject to the option; provided, however, that no stock options shall
be exercisable later than fifteen years after the date they are granted. The
aggregate fair market value at the time of grant of shares of common stock with
respect to which incentive stock options are exercisable for the first time by a
participant during any calendar year cannot be more than $100,000. The exercise
price of an incentive stock option will not be less than 100% of the fair market
value of the common stock on the date the option is granted. The exercise price
of a nonqualified stock option will not be less than 85% of the fair market
value of the common stock on the date the option is granted. The option price
may be paid by a participant in cash or, in the discretion of the compensation
committee, in shares of Whittman-Hart common stock then owned by the
participant, or a combination thereof. At the committee's discretion, it may
also permit broker assisted cashless exercise.



    The plan authorizes the compensation committee to grant a stock appreciation
right either in tandem with a stock option or independent of a stock option. A
stock appreciation right is a right to receive a payment equal to the
appreciation in market value of a stated number of shares of Whittman-Hart
common stock from the exercise price. If issued in tandem with a stock option
such appreciation is measured from not less than the option price and in the
case of a stock appreciation right issued independently of any stock option,
such appreciation is measured from not less than 85% of the fair market value of
the Whittman-Hart common stock on the date the right is granted. No stock
appreciation right may be exercisable earlier than six months after the date of
grant and shall expire at the earlier of the date the related stock option
expires or 15 years after the stock appreciation right was granted.


    The plan authorizes the compensation committee to grant awards in the form
of restricted or unrestricted shares of Whittman-Hart common stock. Such awards
are subject to such terms, conditions, restrictions, and/or limitations, if any,
as the compensation committee deems appropriate including, but not by way of
limitation, restrictions on transferability and continued employment.

    The plan authorizes the compensation committee to grant awards in the form
of performance shares and performance units which consist of the right to
receive common stock or cash of equivalent value at

                                       62
<PAGE>
the end of a specified period. The compensation committee determines the terms
and conditions of the performance units.

    The plan provides that awards shall not be transferable otherwise than by
law or by will or the laws of descent and distribution. Notwithstanding the
foregoing, the compensation committee may issue an award that permits the
transferability of the award to members of the participant's immediate family or
trusts or family partnerships for the benefit of such family members.

    The board of directors reserves the right to amend, suspend or terminate the
plan at any time, subject to the rights of participants with respect to any
outstanding awards. Notwithstanding the foregoing, no amendment to the plan
shall, without approval of stockholders of Whittman-Hart, result in the plan
losing its status as a protected plan under SEC Rule 16b-3.

    The plan contains provisions for equitable adjustment of awards in the event
of a merger, consolidation or reorganization, or issuance of shares by
Whittman-Hart without new consideration or a change of control.

FEDERAL TAX TREATMENT

    Under current law, the following are U.S. federal income tax consequences
generally arising with respect to awards under the plan.

    A participant who is granted an incentive stock option does not recognize
any taxable income at the time of the grant or at the time of exercise.
Similarly, Whittman-Hart is not entitled to any deduction at the time of grant
or at the time of exercise. If the participant makes no disposition of the
shares acquired pursuant to an incentive stock option before the later of two
years from the date of grant and one year from the date of exercise, any gain or
loss realized on a subsequent disposition of the shares will be treated as a
long-term capital gain or loss. Under such circumstances, Whittman-Hart will not
be entitled to any deduction for federal income tax purposes.

    However, if the participant disposes of shares acquired upon exercise of an
incentive stock option within two years after the date of grant or one year
after the date of exercise of the option (a "disqualifying disposition"), the
participant will recognize taxable income in the amount of the excess of the
fair market value of the shares on the date of exercise over the option exercise
price (or, in certain circumstances, the gain on the sale, if less). Any excess
of the amount realized on the disqualifying disposition over the fair market
value of the shares on the date of exercise of the option will generally be
treated as capital gain. In the event of a disqualifying disposition,
Whittman-Hart will be entitled to a deduction equal to the amount of ordinary
compensation income recognized by the participant.

    A participant who is granted a nonqualified stock option will not have
taxable income at the time of grant, but will have taxable income at the time of
exercise equal to the difference between the exercise price of the shares and
the market value of the shares on the date of exercise. Whittman-Hart is
entitled to a tax deduction for the same amount.

    The grant of a stock appreciation right will generally produce no U.S.
federal tax consequences for the participant or Whittman-Hart. The exercise of a
stock appreciation right generally results in taxable income to the participant,
equal to the difference between the exercise price of the shares and the market
price of the shares on the date of exercise, and a corresponding tax deduction
to Whittman-Hart.

    A participant who has been granted an award of restricted shares of
Whittman-Hart common stock will not realize taxable income at the time of the
grant, and Whittman-Hart will not be entitled to a tax deduction at the time of
the grant, unless the participant makes an election to be taxed at the time of
the award. When the restrictions lapse, the participant will recognize taxable
income in an amount equal to the excess of the fair market value of the shares
at such time over the amount, if any, paid for such shares. Whittman-Hart will
be entitled to a corresponding tax deduction.

                                       63
<PAGE>
    The grant of an unrestricted stock award will produce immediate tax
consequences for both the participant and Whittman-Hart. The participant will be
treated as having received taxable income in an amount equal to the then fair
market value of the Whittman-Hart common stock awarded. Whittman-Hart will
receive a corresponding tax deduction.

    A participant who has been granted an award of performance shares or
performance units will not realize taxable income at the time of grant and
Whittman-Hart will not be entitled to a deduction at that time. The participant
will realize taxable income when the shares or cash, as the case may be, are
delivered upon achievement of the performance objectives in an amount equal to
the fair market value of the shares on the date of delivery or payment of cash.
Whittman-Hart will be entitled to a corresponding tax deduction.


THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" APPROVAL OF THE AMENDMENT TO THE
WHITTMAN-HART 1995 INCENTIVE STOCK PLAN INCREASING THE NUMBER OF SHARES OF
COMMON STOCK AVAILABLE FOR ISSUANCE UNDER THE PLAN FROM 24,000,000 SHARES TO
48,000,000 SHARES.

                                    PART II
          INFORMATION NOT REQUIRED IN JOINT PROXY STATEMENT/PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Article Ten of Whittman-Hart's Certificate of Incorporation, filed as
Exhibit 3.1, and Article Eight of the by-laws, filed as Exhibit 3.2, provide
that Whittman-Hart shall indemnify its directors and officers to the full extent
permitted by the Delaware General Corporation Law.

    Section 145 of the Delaware General Corporation Law authorizes a court to
award, or a corporation's Board of Directors to grant, indemnification to
directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities arising under the
Securities Act of 1933. In addition, Article Eight of Whittman-Hart's
Certificate of Incorporation provides that a director of Whittman-Hart shall not
be personally liable to Whittman-Hart or its stockholders for monetary damages
for breach of his or her fiduciary duty as a director, except for liability
(i) for any breach of the director's duty of loyalty to Whittman-Hart or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) under Section 174 of
the General Corporation Law of the State of Delaware, or (iv) for any
transaction from which the director derives an improper personal benefit.

    Reference is made to Section 145 of the General Corporation Law of the State
of Delaware which provides for indemnification of directors and officers in
certain circumstances.

    Whittman-Hart has obtained an insurance policy which will entitle
Whittman-Hart to be reimbursed for certain indemnity payments it is required or
permitted to make to its directors and officers.

    Pursuant to the merger agreement, Whittman-Hart will become obligated to
indemnify present and former USWeb/CKS directors and officers to the full extent
of the law; provided however that the indemnification shall not exceed the
greater of the indemnification provided by USWeb/CKS's Certificate of
Incorporation and by-laws as in effect on December 12, 1999 or the
indemnification actually provided by USWeb/CKS on December 12, 1999. In
addition, for six years Whittman-Hart will maintain in effect the current
USWeb/CKS policies of directors' and officers' liability insurance with respect
to claims arising from facts or events that occur on or before the effective
date of the Merger. Whittman-Hart is not, however, required to expend more than
200% of the current USWeb/CKS annual premium for such insurance.

ITEM 22.  UNDERTAKINGS.

    The Registrant hereby undertakes:

        (1) For purposes of determining any liability under the Securities Act
    of 1933, each filing of the Registrant's annual report pursuant to
    Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by
    reference in this Registration Statement shall be deemed to be a new
    registration statement relating to the securities offered herein, and the
    offering of such securities at that time shall be deemed to be the initial
    bona fide offering thereof.

        (2) To respond to requests for information that is incorporated by
    reference into this joint proxy statement/prospectus pursuant to Items 4,
    10(b), 11, or 13 of this Form, within one business day of receipt of such
    request, and to send the incorporated documents by first class mail or other
    equally prompt means. This includes information contained in documents filed
    subsequent to the effective date of this Registration Statement through the
    date of responding to the request.

        (3) To supply by means of a post-effective amendment all information
    concerning a transaction, and the company being acquired involved therein,
    that was not the subject of and included in this Registration Statement when
    it became effective.

        (4) That prior to any public reoffering of the securities registered
    hereunder through use of a prospectus which is a part of this Registration
    Statement, by any person or party who is deemed to be

                                      II-2
<PAGE>
    an underwriter within the meaning of Rule 145(c), the issuer undertakes that
    such reoffering prospectus will contain the information called for by the
    applicable registration form with respect to reofferings by persons who may
    be deemed underwriters, in addition to the information called for by the
    other items of the applicable form.

        (5) That every prospectus (i) that is filed pursuant to the paragraph
    immediately preceding, or (ii) that purports to meet the requirements of
    section 10(a)(3) of the Act and is used in connection with an offering of
    securities subject to Rule 415 (Section230.415 of this chapter), will be
    filed as a part of an amendment to the registration statement and will not
    be used until such amendment is effective, and that, for purposes of
    determining any liability under the Securities Act of 1933, each such post-
    effective amendment shall be deemed to be a new registration statement
    relating to the securities offered therein, and the offering of such
    securities at that time shall be deemed to be the initial bona fide offering
    thereof.

        (6) Insofar as indemnification for liabilities arising under the
    Securities Act of 1933 may be permitted to directors, officers and
    controlling persons of the Registrant pursuant to the foregoing provisions,
    or otherwise, the registrant has been advised that in the opinion of the
    Securities and Exchange Commission such indemnification is against public
    policy as expressed in the Act and is, therefore, unenforceable. In the
    event that a claim for indemnification against such liabilities (other than
    the payment by the registrant of expenses incurred or paid by a director,
    officer or controlling person of the Registrant in the successful defense of
    any action, suit or proceeding) is asserted by such director, officer or
    controlling person in connection with the securities being registered, the
    Registrant will, unless in the opinion of its counsel the matter has been
    settled by controlling precedent, submit to a court of appropriate
    jurisdiction the question whether such indemnification by it is against
    public policy as expressed in the Act and will be governed by the final
    adjudication of such issue.

    AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated as of December 12,
1999, by and among WHITTMAN-HART, INC., a Delaware corporation ("Parent"),
UNIWHALE, INC., a Delaware corporation and a direct wholly-owned subsidiary of

                                    RECITALS

    WHEREAS, the Board of Directors of each of Parent, Merger Sub and the
Company have determined that it is in the best interests of each corporation and
their respective stockholders that the Company and Parent enter into a strategic
"merger of equals" business combination by means of the merger of Merger Sub
with and into the Company (the "Merger") and, in furtherance thereof, have
approved the Merger and declared the Merger advisable;

    WHEREAS, pursuant to the Merger, the outstanding shares of common stock of
the Company shall be converted into shares of common stock of Parent at the rate
determined herein;

    WHEREAS, for federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization within the meaning of Section 368 of the
Internal Revenue Code of 1986, as amended (the "Code"); WHEREAS, it is intended
that the Merger shall be treated for accounting purposes as a purchase;

    WHEREAS, concurrently with the execution hereof, certain holders (each a
"Voting Stockholder" and collectively the "Voting Stockholders") of Company
Shares and of Parent Shares are entering into a stockholder voting agreement, in
each case in the forms attached as EXHIBIT A-1 and A-2 hereto (each, a
"Stockholders Agreement").

    NOW, THEREFORE, in consideration of the mutual representations, warranties,
covenants and agreements set forth herein, the Parties hereby agree as follows:

                                   ARTICLE IV
    MERGER CONSIDERATION; CONVERSION OR CANCELLATION OF SHARES IN THE MERGER

    4.1  SHARE CONSIDERATION FOR THE MERGER; CONVERSION OR CANCELLATION OF
SHARES IN THE MERGER.  At the Effective Time, the manner of converting or
canceling shares of the Company and Parent shall be as follows:

        (a)  CONVERSION OF COMPANY STOCK.  Each share of common stock, $0.001
    par value ("Company Shares"), of the Company issued and outstanding
    immediately prior to the Effective Time (excluding any Company Shares
    described in Section 4.1(d)), shall, by virtue of the Merger and without any
    action on the part of the holder thereof, be converted automatically into
    the right to receive 0.865 shares of common stock, $0.001 par value, of
    Parent (collectively, "Parent Shares"). All Company Shares to be converted
    into Parent Shares pursuant to this Section 4.1(a) shall, by virtue of the
    Merger and without any action on the part of the holders thereof, cease to
    be outstanding, be canceled and cease to exist, and each holder of a
    certificate representing any such Company Shares shall thereafter cease to
    have any rights with respect to such Company Shares, except the right to
    receive for each of the Company Shares, upon the surrender of such
    certificate in accordance with Section 4.2, the number of Parent Shares
    specified above and cash in lieu of fractional shares. The ratio of Company
    Shares per share of Parent Shares is sometimes hereinafter referred to as
    the "Exchange Ratio."

        (b)  STOCK OF MERGER SUB.  Each share of common stock, $0.01 par value,
    of Merger Sub issued and outstanding immediately prior to the Effective
    Time, shall, by virtue of the Merger and without any action on the part of
    the holder thereof, be converted automatically into and exchanged for one
    (1) validly issued, fully paid and nonassessable share of common stock,
    $0.001 par value, of the

                                      A-2
<PAGE>
    Surviving Corporation. Each stock certificate representing any shares of
    Merger Sub shall continue to represent ownership of such shares of capital
    stock of the Surviving Corporation.

        (c)  OUTSTANDING OPTIONS AND WARRANTS.  Each outstanding option or
    warrant to purchase Company Shares (each, a "Company Option") shall be
    assumed by Parent (in accordance with the further provisions contained in
    Section 6.17) and each such assumed option shall be converted into and
    represent an option to purchase the number of Parent Shares (a "Substitute
    Option") (rounded down to the nearest full share) determined by multiplying
    (i) the number of Company Shares subject to such Company Option immediately
    prior to the Effective Time by (ii) the Exchange Ratio, at an exercise price
    per share of Parent Shares (rounded up to the nearest tenth of a cent) equal
    to the exercise price per share of Company Shares immediately prior to the
    Effective Time divided by the Exchange Ratio. It is the intent of the
    parties that the Company Options assumed by Parent shall qualify following
    the Effective Time as "incentive stock options" as defined in Section 422 of
    the Code to the extent such Company Options qualified as incentive stock
    options immediately prior to the Effective Time and the provisions of this
    Section 4.1(c) shall be applied consistent with such intent. Parent will
    reserve a sufficient number of Parent Shares for issuance under this Section
    4.1(c).

        (d)  CANCELLATION OF PARENT OWNED AND TREASURY STOCK.  All of the
    Company Shares that are owned by Parent, any direct or indirect wholly-owned
    subsidiary of Parent or by the Company as treasury stock shall automatically
    cease to be outstanding, shall be canceled and shall cease to exist and no
    Parent Shares shall be delivered in exchange therefor.

    4.2  PAYMENT FOR SHARES IN THE MERGER.  The manner of making payment for
Shares in the Merger shall be as follows:

        (a)  EXCHANGE AGENT.  On or prior to the Closing Date, Parent shall make
    available to EquiServe, or other entity mutually agreed upon by the Parties
    (the "Exchange Agent"), for the benefit of the holders of Company Shares, a
    sufficient number of certificates representing the Parent Shares required to
    effect the delivery of the aggregate consideration in Parent Shares and cash
    for the Fractional Securities Fund required to be issued pursuant to Section
    4.1 (collectively, the "Share Consideration" and the certificates
    representing the Parent Shares comprising such aggregate Share Consideration
    being referred to hereinafter as the "Stock Merger Exchange Fund"). The
    Exchange Agent shall, pursuant to irrevocable instructions, deliver the
    Share Consideration out of the Stock Merger Exchange Fund and the Fractional
    Securities Fund. The Stock Merger Exchange Fund and the Fractional
    Securities Fund shall not be used for any other purpose than as set forth
    herein.

        (b)  EXCHANGE PROCEDURES.  Promptly after the Effective Time, the
    Exchange Agent shall mail to each holder of record of a certificate or
    certificates which immediately prior to the Effective Time represented
    outstanding Company Shares (the "Certificates") (i) a form of letter of
    transmittal, in a form reasonably satisfactory to the Parties (which shall
    specify that delivery shall be effected, and risk of loss and title to the
    Certificates shall pass, only upon proper delivery of the Certificates to
    the Exchange Agent) and (ii) instructions for use in effecting the surrender
    of the Certificates for payment therefor. Upon surrender of Certificates for
    cancellation to the Exchange Agent, together with such letter of transmittal
    duly executed and any other required documents, the holder of such
    Certificates shall be entitled to receive for each of the Company Shares
    represented by such Certificates the Share Consideration, without interest,
    allocable to such Certificates and the Certificates so surrendered shall
    forthwith be canceled. Until so surrendered, such Certificates shall
    represent solely the right to receive the Share Consideration allocable to
    such Certificates.

        (c)  DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.  No dividends or
    other distributions that are declared after the Effective Time on Parent
    Shares and payable to the holders of record thereof after the Effective Time
    will be paid to Persons entitled by reason of the Merger to receive Parent
    Shares until such Persons surrender their Certificates as provided above.
    Upon such surrender, there shall be paid to the Person in whose name the
    Parent Shares are issued any dividends or other

                                      A-3
<PAGE>
    distributions having a record date after the Effective Time and payable with
    respect to such Parent Shares between the Effective Time and the time of
    such surrender. After such surrender there shall be paid to the Person in
    whose name the Parent Shares are issued any dividends or other distributions
    on such Parent Shares which shall have a record date after the Effective
    Time. In no event shall the Persons entitled to receive such dividends or
    other distributions be entitled to receive interest on such dividends or
    other distributions.

        (d)  TRANSFERS OF OWNERSHIP.  If any certificate representing Parent
    Shares is to be issued in a name other than that in which the Certificate
    surrendered in exchange therefor is registered, it shall be a condition of
    such exchange that the Certificate so surrendered shall be properly endorsed
    and otherwise in proper form for transfer and that the Person requesting
    such exchange shall pay to the Exchange Agent any transfer or other taxes
    required by reason of the issuance of certificates for such Parent Shares in
    a name other than that of the registered holder of the Certificate
    surrendered, or shall establish to the satisfaction of the Exchange Agent
    that such tax has been paid or is not applicable.

        (e)  NO LIABILITY.  Neither the Exchange Agent nor any of the Parties
    shall be liable to a holder of Company Shares for any Parent Shares or
    dividends thereon, or, in accordance with Section 4.3, cash in lieu of
    fractional Parent Shares, delivered to a public official pursuant to
    applicable escheat law. The Exchange Agent shall not be entitled to vote or
    exercise any rights of ownership with respect to the Parent Shares held by
    it from time to time hereunder, except that it shall receive and hold all
    dividends or other distributions paid or distributed with respect to such
    Parent Shares for the account of the Persons entitled thereto.

        (f)  TERMINATION OF FUNDS.  Subject to applicable law, any portion of
    the Stock Merger Exchange Fund and the Fractional Securities Fund which
    remains unclaimed by the former stockholders of the Company for one
    (1) year after the Effective Time shall be delivered to Parent, upon demand
    of Parent, and any former stockholder of the Company shall thereafter look
    only to Parent for payment of their applicable claim for the Share
    Consideration for their Company Shares.

    4.3  CASH FOR FRACTIONAL PARENT SHARES.  No fractional Parent Shares shall
be issued in the Merger. Each holder of Parent Shares shall be entitled to
receive in lieu of any fractional Parent Shares to which such holder otherwise
would have been entitled pursuant to Section 4.2 (after taking into account all
Parent Shares then held of record by such holder) a cash payment in an amount
equal to the product of (i) the fractional interest of a Parent Share to which
such holder otherwise would have been entitled and (ii) the closing price of a
Parent Share on the NASDAQ National Market ("NNM") on the trading day
immediately prior to the Effective Time (the cash comprising such aggregate
payments in lieu of fractional Parent Shares being hereinafter referred to as
the "Fractional Securities Fund").

    4.4  TRANSFER OF SHARES AFTER THE EFFECTIVE TIME.  No transfers of Company
Shares shall be made on the stock transfer books of the Company after the close
of business on the day prior to the date of the Effective Time.

                                   ARTICLE V
                         REPRESENTATIONS AND WARRANTIES

    5.1  REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB.  Parent and
Merger Sub hereby represent and warrant to the Company that the statements
contained in this Section 5.1 are true and correct, except to the extent
specifically set forth on the disclosure schedule previously delivered by Parent
to the Company (the "Parent Disclosure Schedule"). The Parent Disclosure
Schedule shall be arranged in sections and paragraphs corresponding to the
letter and numbered paragraphs contained in this Section 5.1, and the disclosure
in any paragraph shall qualify only the corresponding paragraph in this Section
5.1 or other paragraphs or sections to which it is clearly apparent (from a
plain reading of the disclosure) that such disclosure relates.

                                      A-4
<PAGE>
        (a)  CORPORATE ORGANIZATION AND QUALIFICATION.  Each of Parent and its
    subsidiaries is a corporation duly organized, validly existing and in good
    standing under the laws of the jurisdiction of incorporation and is
    qualified and in good standing as a foreign corporation in each jurisdiction
    where the properties owned, leased or operated, or the business conducted,
    by it require such qualification, except where failure to so qualify or be
    in good standing as a foreign corporation would not have a Material Adverse
    Effect on Parent. Each of Parent and its subsidiaries has all requisite
    power and authority (corporate or otherwise) to own its properties and to
    carry on its business as it is now being conducted. All of the subsidiaries
    of Parent are set forth in Section 5.1(a) of the Parent Disclosure Schedule.
    Parent has heretofore made available to the Company complete and correct
    copies of its Certificate of Incorporation and Bylaws and the charter
    documents of its subsidiaries, each as amended. Merger Sub is a direct,
    wholly-owned subsidiary of Parent, was formed solely for the purpose of
    engaging in the transactions contemplated hereby, has engaged in no other
    business activities and has conducted its operations only as contemplated
    hereby.

        (b)  CAPITALIZATION.  The authorized capital stock of Parent consists of
    (i) 75,000,000 shares of common stock, $0.001 par value per share, of which
    61,784,097 shares were issued and outstanding on December 9, 1999 and (ii)
    3,000,000 shares of preferred stock, $0.001 par value per share, none of
    which are issued or outstanding. All of the outstanding shares of capital
    stock of Parent and its subsidiaries have been duly authorized and validly
    issued and are fully paid and nonassessable. Parent has no outstanding stock
    appreciation rights, phantom stock or similar rights. No Parent Shares are
    owned by any subsidiary of Parent. All outstanding shares of capital stock
    or other equity interests of the subsidiaries of Parent are owned by Parent
    or a direct or indirect wholly-owned subsidiary of Parent, free and clear of
    all liens, pledges, charges, encumbrances, claims and options of any nature.
    Except for options to purchase 16,831,629 Parent Shares as of December 9,
    1999 under the 1995 Incentive Stock Plan (the "Parent Option Plans") and
    rights under Parent Employee Stock Purchase Plan, there are no outstanding
    or authorized options, warrants, calls, rights (including preemptive
    rights), commitments or any other agreements of any character which Parent
    or any of its subsidiaries is a party to, or may be bound by, requiring it
    to issue, transfer, grant, sell, purchase, redeem or acquire any shares of
    capital stock or any securities or rights convertible into, exchangeable
    for, or evidencing the right to subscribe for, any shares of capital stock
    of Parent or any of its subsidiaries. There are not as of the date hereof
    and there will not be at the Effective Time any stockholder agreements,
    voting trusts or other agreements or understandings to which Parent is a
    party or to which it is bound relating to the voting of any shares of the
    capital stock of Parent.

        (c)  FAIRNESS OPINION.  The Board of Directors of Parent has received an
    opinion in writing from Credit Suisse First Boston Corporation to the effect
    that as of the date hereof and based upon and subject to the matters stated
    therein, the Exchange Ratio is fair to Parent from a financial point of
    view. As of the date hereof, such opinion has not been withdrawn, revoked or
    modified.

        (d)  AUTHORITY RELATIVE TO THIS AGREEMENT.  The Board of Directors of
    Merger Sub has declared the Merger advisable and Merger Sub has the
    requisite corporate power and authority to approve, authorize, execute and
    deliver this Agreement and to consummate the transactions contemplated
    hereby. The Board of Directors of Parent has declared the issuance of Parent
    Shares advisable and Parent has the requisite corporate power and authority
    to approve, authorize, execute and deliver this Agreement and, subject to
    the approval by the stockholders of Parent of the amendment to Parent's
    Certificate of Incorporation to increase Parent's authorized capital stock
    in order to allow for the issuance of Parent Shares by virtue of the Merger
    and the approval of the issuance of Parent Shares by the stockholders of
    Parent in accordance with the NNM listing requirements, to consummate the
    transactions contemplated hereby. This Agreement and the consummation by
    Parent of the transactions contemplated hereby have been duly and validly
    authorized by the Boards of Directors of Parent and Merger Sub and no other
    corporate proceedings on the part of Parent or Merger Sub (including, in the
    case of Merger Sub, all stockholder action by Parent as its sole
    stockholder) are necessary to

                                      A-5
<PAGE>
    authorize this Agreement or to consummate the transactions contemplated
    hereby (other than the approval by the stockholders of Parent of the
    amendment to Parent's Certificate of Incorporation to increase Parent's
    authorized capital stock in order to allow for the issuance of Parent Shares
    by virtue of the Merger and the approval of the issuance of Parent Shares by
    the stockholders of Parent in accordance with the NNM listing requirements).
    This Agreement has been duly and validly executed and delivered by Parent
    and Merger Sub and, assuming this Agreement constitutes the valid and
    binding agreement of the Company, constitutes the valid and binding
    agreement of Parent and Merger Sub, enforceable against Parent and Merger
    Sub in accordance with its terms, subject, as to enforceability, to
    bankruptcy, insolvency, reorganization and other laws of general
    applicability relating to or affecting creditors' rights and to general
    principles of equity.

        (e)  PRESENT COMPLIANCE WITH OBLIGATIONS AND LAWS.  Neither Parent nor
    any of its subsidiaries is: (i) in violation of its Certificate of
    Incorporation or Bylaws or similar documents; (ii) in default in the
    performance of any obligation, agreement or condition of any debt instrument
    which (with or without the passage of time or the giving of notice, or both)
    affords to any Person the right to accelerate any indebtedness or terminate
    any right; (iii) in default under or breach of (with or without the passage
    of time or the giving of notice) any other contract to which it is a party
    or by which it or its assets are bound; or (iv) in violation of any law,
    regulation, administrative order or judicial order, decree or judgment
    (domestic or foreign) applicable to it or its business or assets, except
    where any violation, default or breach under items (ii), (iii), or
    (iv) would not, individually or in the aggregate, have a Material Adverse
    Effect on Parent.

        (f)  CONSENTS AND APPROVALS; NO VIOLATION.  Neither the execution and
    delivery of this Agreement nor the consummation by Parent of the
    transactions contemplated hereby will (i) conflict with or result in any
    breach of any provision of the respective Certificate of Incorporation (or
    other similar documents) or Bylaws (or other similar documents) of Parent or
    any of its subsidiaries; (ii) require any consent, approval, authorization
    or permit of, or registration or filing with or notification to, any
    governmental or regulatory authority, except (A) in connection with the
    applicable requirements, if any, of the Hart-Scott-Rodino Antitrust
    Improvements Act of 1976, as amended (the "HSR Act"), (B) pursuant to the
    applicable requirements of the Securities Act of 1933, as amended (the
    "Securities Act"), and the rules and regulations promulgated thereunder, and
    the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
    the rules and regulations promulgated thereunder, (C) the filing of the
    Certificate of Merger pursuant to the DGCL and appropriate documents with
    the relevant authorities of other states in which Parent is authorized to do
    business, (D) as may be required by any applicable state securities laws,
    (E) the consents, approvals, orders, authorizations, registrations,
    declarations and filings required under the antitrust laws of foreign
    countries, as set forth in Section 5.1(f) of the Parent Disclosure Schedule,
    or (F) where the failure to obtain such consent, approval, authorization or
    permit, or to make such filing or notification, would not in the aggregate
    have a Material Adverse Effect on Parent or adversely affect the ability of
    Parent to consummate the transactions contemplated hereby; (iii) result in a
    violation or breach of, or constitute (with or without notice or lapse of
    time or both) a default (or give rise to any right of termination,
    cancellation or acceleration or lien or other charge or encumbrance) under
    any of the terms, conditions or provisions of any indenture, note, license,
    lease, agreement or other instrument or obligation to which Parent or any of
    its subsidiaries is a party or by which any of their assets may be bound,
    except for such violations, breaches and defaults (or rights of termination,
    cancellation or acceleration or lien or other charge or encumbrance) as to
    which requisite waivers or consents have been obtained or which, in the
    aggregate, would not have a Material Adverse Effect on Parent or adversely
    affect the ability of Parent to consummate the transactions contemplated
    hereby; (iv) cause the suspension or revocation of any authorizations,
    consents, approvals or licenses currently in effect which would have a
    Material Adverse Effect on Parent; or (v) assuming the consents, approvals,
    authorizations or permits and filings or notifications referred to in this
    Section 5.1(f) are duly and timely obtained or made and the approval by the
    stockholders of Parent of the amendment to Parent's

                                      A-6
<PAGE>
    Certificate of Incorporation to increase parent's authorized capital stock
    in order to allow for the issuance of Parent Shares by virtue of the Merger
    and approval of the issuance of the Parent Shares by the stockholders of
    Parent in accordance with the NNM listing requirements have been obtained,
    violate any order, writ, injunction, decree, statute, rule or regulation
    applicable to Parent or any of its subsidiaries or to any of their
    respective assets, except for violations which would not in the aggregate
    have a Material Adverse Effect on Parent or adversely affect the ability of
    Parent to consummate the transactions contemplated hereby.

        (g)  LITIGATION.  There are no actions, suits, claims, investigations or
    proceedings pending or, to the knowledge of Parent, threatened against
    Parent or any of its subsidiaries that, alone or in the aggregate would be
    reasonably likely to result in obligations or liabilities of Parent or any
    of its subsidiaries that, alone or in the aggregate, would have a Material
    Adverse Effect on Parent or a material adverse effect on the parties'
    ability to consummate the transactions contemplated by this Agreement.
    Neither Parent nor any of its subsidiaries is subject to any outstanding
    order, writ, injunction or decree which (i) has or may have the effect of
    prohibiting or impairing any business practice of Parent or any of its
    subsidiaries, any acquisition of property (tangible or intangible) by Parent
    or any of its subsidiaries, the conduct of the business by Parent or any of
    its subsidiaries, or Parent's ability to perform its obligations under this
    Agreement or (ii) insofar as can be reasonably foreseen, individually or in
    the aggregate, would have a Material Adverse Effect on Parent.

        (h)  SEC REPORTS; FINANCIAL STATEMENTS.

           (i) Since January 1, 1997, Parent has filed all forms, reports and
       documents with the Securities and Exchange Commission (the "SEC")
       required to be filed by it pursuant to the federal securities laws and
       the SEC rules and regulations thereunder, all of which complied in all
       material respects with all applicable requirements of the Securities Act
       and the Exchange Act and the rules and regulations promulgated thereunder
       (collectively, the "Parent SEC Reports"). None of the Parent SEC Reports,
       including, without limitation, any financial statements or schedules
       included therein, at the time filed (or if amended or superseded by a
       filing prior to the date of this Agreement, then on the date of such
       filing) contained any untrue statement of a material fact or omitted to
       state a material fact required to be stated therein or necessary in order
       to make the statements therein, in light of the circumstances under which
       they were made, not misleading. None of Parent's subsidiaries is required
       to file any forms, reports or other documents with the SEC.

           (ii) The consolidated balance sheets and the related consolidated
       statements of income, stockholders' equity (deficit) and cash flows
       (including the related notes thereto) of Parent included in the Parent
       SEC Reports (collectively, "Parent Financial Statements") comply as to
       form in all material respects with applicable accounting requirements and
       the published rules and regulations of the SEC with respect thereto, have
       been prepared in accordance with generally accepted accounting principles
       applied on a basis consistent throughout the periods involved (except as
       otherwise noted therein or, in the case of unaudited interim financial
       statements, as may be permitted by the SEC on Form 10-Q under the
       Exchange Act), and present fairly the consolidated financial position of
       Parent and its consolidated subsidiaries as of their respective dates,
       and the consolidated results of their operations and their cash flows for
       the periods presented therein (subject, in the case of the unaudited
       interim financial statements, to normal and recurring year-end
       adjustments). Since January 1, 1999, there has not been any material
       change, by Parent or any of its subsidiaries, in accounting principles,
       methods or policies for financial accounting purposes except as required
       by concurrent changes in generally accepted accounting principles.

        (i)  NO LIABILITIES; ABSENCE OF CERTAIN CHANGES OR EVENTS.  Neither
    Parent nor any of its subsidiaries has any material indebtedness,
    obligations or liabilities of any kind (whether accrued, absolute,

                                      A-7
<PAGE>
    contingent or otherwise, and whether due or to become due or asserted or
    unasserted), and, to knowledge of Parent, there is no reasonable basis for
    the assertion of any material claim or liability of any nature against
    Parent or any of its subsidiaries, except for liabilities (i) which are
    fully reflected in, reserved against or otherwise described in the Parent
    Financial Statements for the period ending September 30, 1999, (ii) which
    have been incurred after September 30, 1999 in the ordinary course of
    business, consistent with past practice, or (iii) which are obligations to
    perform under executory contracts in the ordinary course of business (none
    of which is a liability resulting from a breach of contract or warranty,
    tort, infringement or legal action). Since September 30, 1999, the business
    of Parent and its subsidiaries has been carried on only in the ordinary and
    usual course, and there has not been any Material Adverse Effect on Parent
    and no event has occurred and no fact or set of circumstances has arisen
    which has resulted in or could reasonably be expected to result in a
    Material Adverse Effect on Parent. Since September 30, 1999, to the
    knowledge of Parent, no material customer or supplier of Parent or its
    subsidiaries has threatened, in writing, to alter materially its
    relationship with Parent or its subsidiaries. Since September 30, 1999,
    neither Parent nor any of its subsidiaries has agreed to a waiver or release
    of any material right or claim (including without limitation to any write
    off or other compromise of any material account receivable) outside of the
    ordinary course of business consistent with past practice.

        (j)  BROKERS AND FINDERS.  Except for the fees and expenses payable to
    Credit Suisse First Boston or Launchpad Consulting, LLC, which fees and
    expenses are reflected in their agreements with Parent, a true and complete
    copy of which (including all amendments) has been furnished to the Company,
    neither Parent nor any of its subsidiaries has employed any investment
    banker, broker, finder, consultant or intermediary in connection with the
    transactions contemplated by this Agreement which would be entitled to any
    investment banking, brokerage, finder's or similar fee or commission in
    connection with this Agreement or the transactions contemplated hereby.

        (k)  S-4 REGISTRATION STATEMENT AND PROXY STATEMENT/PROSPECTUS.  None of
    the information supplied or to be supplied by Parent for inclusion or
    incorporation by reference in the S-4 Registration Statement or the Joint
    Proxy Statement will (i) in the case of the S-4 Registration Statement, at
    the time it becomes effective or at the Effective Time, contain any untrue
    statement of a material fact or omit to state any material fact required to
    be stated therein or necessary in order to make the statements therein not
    misleading, or (ii) in the case of the Joint Proxy Statement, at the time of
    the mailing of the Joint Proxy Statement and at the time of the Stockholder
    Meetings, contain any untrue statement of a material fact or omit to state
    any material fact required to be stated therein or necessary in order to
    make the statements therein, in light of the circumstances under which they
    are made, not misleading. If at any time prior to the Effective Time any
    event with respect to Parent, Merger Sub or any of their respective
    affiliates, officers and directors or any of its subsidiaries should occur
    which is required to be described in an amendment of, or a supplement to,
    the Joint Proxy Statement or the S-4 Registration Statement, Parent should
    promptly inform the Company, such event shall be so described, and such
    amendment or supplement shall be promptly filed with the SEC and, as
    required by law, disseminated to the stockholders of Parent and the Company.
    The S-4 Registration Statement will (with respect to Parent and Merger Sub)
    comply as to form in all material respects with the requirements of the
    Securities Act and the rules and regulations promulgated thereunder. The
    Joint Proxy Statement will (with respect to Parent and Merger Sub) comply as
    to form in all material respects with the requirements of the Exchange Act
    and the rules and regulations promulgated thereunder.

        (l)  TAXES.

           (i) Parent and each of its subsidiaries has timely filed all federal,
       state, local and foreign returns, information statements and reports
       relating to Taxes ("Returns") required by applicable Tax law to be filed
       by Parent and each of its subsidiaries, except for any such failures to
       file that could not reasonably be expected to have, individually or in
       the aggregate, a Material Adverse

                                      A-8
<PAGE>
           Effect on Parent. All Taxes owed by Parent or any of its subsidiaries
           to a taxing authority, or for which Parent or any of its subsidiaries
           is liable, whether to a taxing authority or to other Persons or
           entities under a Significant Tax Agreement, as of the date hereof,
           have been paid and, as of the Effective Time, will have been paid,
           except for any such failure to pay that could not reasonably be
           expected to have, individually or in the aggregate, a Material
           Adverse Effect on Parent. Parent has made accruals for Taxes on the
           Parent Financial Statements which are adequate to cover any Tax
           liability of Parent and each of its subsidiaries determined in
           accordance with generally accepted accounting principles through the
           date of the Parent Financial Statements, except where failures to
           make such accruals or provisions could not reasonably be expected to
           have, individually or in the aggregate, a Material Adverse Effect on
           Parent.

           (ii) Except to the extent that any such failure to withhold could not
       reasonably be expected to have, individually or in the aggregate, a
       Material Adverse Effect on Parent, Parent and each of its subsidiaries
       have withheld with respect to its employees all federal and state income
       taxes, FICA, FUTA and other Taxes required to be withheld.

          (iii) There is no Tax deficiency outstanding, proposed or assessed
       against Parent or any of its subsidiaries, except any such deficiency
       that, if paid, could not reasonably be expected to have, individually or
       in the aggregate, a Material Adverse Effect on Parent. Neither Parent nor
       any of its subsidiaries executed or requested any waiver of any statute
       of limitations on or extending the period for the assessment or
       collection of any federal or material state Tax that is still in effect.

           (iv) No federal or state Tax audit or other examination of Parent or
       any of its subsidiaries is presently in progress, nor has Parent or any
       of its subsidiaries been notified in writing of any request for such
       federal or material state Tax audit or other examination, except in all
       cases for Tax audits and other examinations which could not reasonably be
       expected to have, individually or in the aggregate, a Material Adverse
       Effect on Parent.

           (v) Neither Parent nor any of its subsidiaries has filed any consent
       agreement under Section 341(f) of the Code or agreed to have
       Section 341(f)(2) of the Code apply to any disposition of a subsection
       (f) asset (as defined in Section 341(f)(4) of the Code) owned by Parent.

           (vi) Neither Parent nor any of its subsidiaries is a party to (A) any
       agreement with a party other than Parent or any of its subsidiaries
       providing for the allocation or payment of Tax liabilities or payment for
       Tax benefits with respect to a consolidated, combined or unitary Return
       which Return includes or included Parent or any subsidiary or (B) any
       Significant Tax Agreement other than any Significant Tax Agreement
       described in (A).

          (vii) Except for the group of which Parent and its subsidiaries are
       now presently members, neither Parent nor any of its subsidiaries has
       ever been a member of an affiliated group of corporations within the
       meaning of Section 1504 of the Code.

         (viii) Neither Parent nor any of its subsidiaries has agreed to make
       nor is it required to make any adjustment under Section 481(a) of the
       Code by reason of a change in accounting method or otherwise which have
       not yet been taken into account.

           (ix) Parent is not, and has not at any time been, a "United States
       Real Property Holding Corporation" within the meaning of
       Section 897(c)(2) of the Code.

        (m)  EMPLOYEE BENEFITS.

       defined in Section 3(1) of ERISA), material personnel or payroll policy

                                      A-9

       reduction agreement, change-of-control agreement, employment agreement,

       agreement, or retainer agreement, or any other material benefit plan,
       policy, program, arrangement, agreement or contract, whether or not
       written or terminated, with respect to any employee, former employee,
       director, independent contractor, or any beneficiary or dependent thereof
       maintained, sponsored, adopted or administered by Parent or any current
       or former Plan Affiliate or to which Parent or any current or former Plan
       Affiliate has made contributions to, obligated itself or had any
       liability with respect to (all such plans, policies, programs,
       arrangements, agreements and contracts, whether or not set forth in
       Section 5.1(m) of the Parent Disclosure Schedule or on the Parent
       Financial Statements are referred to in this Agreement as "Parent
       Scheduled Plans").

           (ii) Parent has delivered or made available to the Company a complete
       and accurate copy of each written Parent Scheduled Plan, together with,
       if applicable, a copy of audited financial statements, actuarial reports
       and Form 5500 Annual Reports (including required schedules), if any, for
       the three (3) most recent plan years, the most recent IRS determination
       letter or IRS recognition of exemption; each other material letter,
       ruling or notice issued by a governmental body with respect to each such
       plan, a copy of each trust agreement, insurance contract or other funding
       vehicle, if any, with respect to each such plan, the most recent PBGC

       in Code Section 162(i), and a copy or description of each other general
       explanation or written or oral communication which describes a material

       to the Company pursuant to this Section. Section 5.1(m) of the Parent
       Disclosure Schedule contains a description of the material terms of any
       unwritten Parent Scheduled Plan as comprehended to the Closing Date.
       Except as set forth in Section 5.1(m) of the Parent Disclosure Schedule,
       there are no negotiations, demands or proposals which are pending or
       threatened which concern matters now covered, or that would be covered,
       by the foregoing types of unwritten Plans.

          (iii) Except as could not reasonably give rise, whether individually
       or in the aggregate, to a Material Adverse Effect to Parent or Merger
       Sub:

               (1) Each Parent Scheduled Plan (A) has been and currently

           for both Federal and state purposes, for income tax exclusions to its
           participants, tax-exempt income for its funding vehicle, and the
           allowance of deductions and credits with respect to contributions
           thereto; and (D) where appropriate, has received a favorable
           determination letter or recognition of exemption from the Internal

                                      A-10
<PAGE>
               (2) With respect to each Parent Scheduled Plan, there are no
           claims or other proceedings pending or, to the knowledge of Parent,
           threatened with respect to the assets thereof (other than routine
           claims for benefits), and there are no facts which could reasonably
           give rise to any material liability, claim or other proceeding
           against any Parent Scheduled Plan, any fiduciary or plan
           administrator or other Person dealing with any Parent Scheduled Plan
           or the assets of any such Parent Scheduled Plan.

               (3) With respect to each Parent Scheduled Plan, to the knowledge
           of Parent, no Person: (A) has entered into any "prohibited
           transaction," as such term is defined in ERISA or the Code and the
           regulations, administrative rulings and case law thereunder that is
           not otherwise exempt under Code Section 4975 or ERISA Section 408 (or
           any administrative class exemption issued thereunder); (B) has
           materially breached a fiduciary obligation or violated Sections 402,
           403, 405, 503, 510 or 511 of ERISA; (C) has any material liability
           for any failure to act or comply in connection with the
           administration or investment of the assets of such plans; or
           (D) engaged in any transaction or otherwise acted with respect to
           such plans in such a manner which could subject the Company, or any
           fiduciary or plan administrator or any other Person dealing with any
           such plan, to material liability under Section 409 or 502 of ERISA or
           Sections 4972 or 4976 through 4980B of the Code.

               (4) Each Parent Scheduled Plan (other than any stock option plan)
           may be amended, terminated, modified or otherwise revised by Parent,
           on and after the Closing, without further material liability to
           Parent (other than ordinary administrative expenses or routine claims
           for benefit plans), including, but not limited to, any withdrawal
           liability under ERISA for any multi-employer plan or any liability
           under any Parent Scheduled Plan subject to Title IV of ERISA.

               (5) None of Parent or any current or former Parent Plan Affiliate
           has at any time participated in, made contributions to or had any
           other liability with respect to any Parent Scheduled Plan which is a
           "multi-employer plan" as defined in Section 4001 of ERISA, a
           "multi-employer plan" within the meaning of Section 3(37) of ERISA, a
           "multiple employer plan" within the meaning of Section 413(c) of the
           Code, a "multiple employer welfare arrangement" within the meaning of
           Section 3(40) of ERISA or a plan that is subject to Title IV of
           ERISA.

               (6) No Parent Scheduled Plan provides, or reflects or represents
           any liability to provide retiree health to any person for any reason,
           except as may be required by COBRA or other applicable statute, and
           neither Parent nor any Plan Affiliate has ever represented, promised
           or contracted (whether in oral or written form) to any current or
           former employee, consultant or director (either individually or as a
           group) or any other person that such current or former employee(s) or
           other person would be provided with retiree health, except to the
           extent required by applicable continuation coverage statute.

               (7) No Parent Scheduled Plan has incurred an "accumulated funding
           deficiency" as such term is defined in Section 302 of ERISA or
           Section 412 of the Code, whether or not waived, or has posted or is
           required to provide security under Code Section 401(a)(29) or
           Section 307 of ERISA; no event has occurred which has or could result
           in the imposition of a lien under Code Section 412 or Section 302 of
           ERISA, nor has any liability to the Pension Benefit Guaranty
           Corporation (the "PBGC") (except for payment of premiums) been
           incurred or reportable event within the meaning of Section 4043 of
           ERISA occurred with respect to any such plan; and the PBGC has not
           threatened or taken steps to institute the termination of any such
           plan;

               (8) The requirements of COBRA and the Health Insurance
           Portability and Accountability Act, the requirements of the Family
           Medical Leave Act of 1993, as amended, the

                                      A-11
<PAGE>
           requirements of the Women's Health and Cancer Rights Act, the
           requirements of the Newborns' and Mothers' Health Protection Act of
           1996, or any amendment to each such act, or any similar provisions of
           state law applicable to its employees, have, in all material
           respects, been satisfied with respect to each Parent Scheduled Plan.

               (9) All contributions, payments, premiums, expenses,
           reimbursements or accruals for all periods ending prior to or as of
           the Closing for each Parent Scheduled Plan (including periods from
           the first day of the then current plan year to the Closing) shall
           have been made or accrued on Parent financial statements (in
           accordance with generally applied accounting principles, including
           FAS 87, 88, 106 and 112) and each such plan otherwise does not have
           nor could have any unfunded liability (including benefit liabilities
           as defined in Section 4001(a)(16) of ERISA) which is not reflected on
           Parent financial statements. Any contribution made or accrued with
           respect to any Parent Scheduled Plan has been or, to the knowledge of
           Parent, will be intended to be, fully deductible by Parent.

              (10) Neither Parent nor a Plan Affiliate has any material
           liability (A) for the termination of any single employer plan under
           Section 4062 of ERISA or any multiple employer plan under
           Section 4063 of ERISA, (B) for any lien imposed under
           Section 302(f) of ERISA or Section 412(n) of the Code, (C) for any
           interest payments required under Section 302(e) of ERISA or
           Section 412(m) of the Code, (D) for any excise tax imposed by Code
           Sections 4971, 4972, 4977, or 4979, or (E) for any minimum funding
           contributions under Section 302(c)(11) of ERISA or Code
           Section 412(c)(11).

              (11) All Parent Scheduled Plans to the extent applicable, are in
           compliance with Section 1862(b)(1)(A)(i) of the Social Security Act
           and neither Parent nor any Plan Affiliate has any liability for any
           excise tax imposed by Code Section 5000.

              (12) With respect to any Parent Scheduled Plan which is a welfare
           plan as defined in Section 3(1) of ERISA; (A) each such welfare plan
           which is intended to meet the requirements for tax-favored treatment
           under Subchapter B of Chapter 1 of the Code materially meets such
           requirements; and (B) there is no disqualified benefit (as such term
           is defined in Code Section 4976(b)) which would subject Parent or any
           Plan Affiliate to a tax under Code Section 4976(a).

              (13) Each Parent Scheduled Plan that has been adopted or
           maintained by Parent or any Plan Affiliate, whether informally or
           formally, or with respect to which Parent or any Plan Affiliate will
           or may have any liability, for the benefit of Parent Employees who
           perform services outside the United States (the "Parent International
           Employee Plans") has been established, maintained and administered in
           material compliance with its terms and conditions and with the
           requirements prescribed by any and all statutory or regulatory laws
           that are applicable to such Parent International Employee Plan.
           Furthermore, no Parent International Employee Plan has unfunded
           liabilities, that, as of the Effective Time, will not be offset by
           insurance or fully accrued. Except as required by law, no condition
           exists that would prevent Parent or any Plan Affiliate from
           terminating or amending any Parent International Employee Plan at any
           time for any reason without material liability to Parent or any Plan
           Affiliate (other than ordinary administration expenses or routine
           claims for benefits). To the extent any such Parent International
           Employee Plan has not been disclosed or provided prior to the date of
           this Agreement, Parent agrees to use its best efforts to disclose and
           provide such plan prior to the Effective Time.

           (iv) Other than by reason of actions taken by Parent following the
       Closing, the consummation of the transactions contemplated by this
       Agreement will not (A) entitle any current or former employee of Parent
       to severance pay, unemployment compensation or any other payment,
       (B) accelerate the time of payment or vesting of any payment (other than
       for a terminated or

                                      A-12

       frozen tax-qualified plan, pursuant to a requirement herein to freeze or
       terminate such plan), cause the forgiveness of any indebtedness, or
       increase the amount of any compensation due to any such employee or
       former employee, (C) result in any prohibited transaction described in
       Section 406 of ERISA or Section 4975 of the Code for which an exemption
       is not available, or (D) give rise to the payment of any amount that
       would not be deductible pursuant to the terms of Section 280G of the
       Code.

           (v) As used in this Agreement, with respect to any Person the term
       "Plan Affiliate" shall mean each other Person with whom such Person
       constitutes or has constituted all or part of a controlled group, or
       which would be treated or has been treated with such Person as under
       common control or whose employees would be treated or have been treated
       as employed by such Person, under Section 414 of the Code and any
       regulations, administrative rulings and case law interpreting the
       foregoing.

        (n)  PARENT INTANGIBLE PROPERTY.

           (i) Parent and its subsidiaries own, or are licensed or otherwise
       possess legally enforceable rights to use, all patents, trademarks, trade
       names, service marks, copyrights and mask works, all applications for and
       registrations of such patents, trademarks, trade names, service marks,
       copyrights and mask works, and all processes, formulae, methods,
       schematics, technology, know-how, computer software programs or
       applications and tangible or intangible proprietary information or
       material that are necessary to conduct the business of Parent and its
       subsidiaries as currently conducted or planned to be conducted (the
       "Parent Intellectual Property Rights"). Section 5.1(n) of the Parent
       Disclosure Schedule sets forth a list of the material software licenses
       to which Parent or its subsidiaries is a party.

           (ii) Neither Parent nor any of its subsidiaries is or will be as a
       result of the execution and delivery of this Agreement or the performance
       of its obligations under this Agreement, in breach in any material
       respect of any material license, sublicense or other agreement relating
       to the Parent Intellectual Property Rights or any license, sublicense or
       other agreement pursuant to which Parent or any of its subsidiaries is
       authorized to use any third party patents, trademarks or copyrights,
       including software, which are used in the manufacture of, incorporated
       in, or form a part of any product of Parent or any of its subsidiaries.

          (iii) To Parent's knowledge, all patents, registered trademarks,
       service marks and copyrights held by Parent or any of its subsidiaries
       which are material to its business are valid and enforceable. Neither
       Parent nor any of its subsidiaries has been sued in any suit, action or
       proceeding which involves a claim of infringement of any patent,
       trademark, service mark or copyright or the violation of any trade secret
       or other proprietary rights of any third party, which infringement would
       be reasonably likely to have a Material Adverse Effect on Parent.

           (iv) Parent and its subsidiaries have taken reasonable security
       measures to safeguard and maintain their property rights in all Parent
       Intellectual Property Rights owned by Parent or its subsidiaries. Parent
       and its subsidiaries maintain and in all material respects abide by a
       policy that officers, employees and consultants of Parent or any of its
       subsidiaries, except for clerical and other lower level support personnel
       (e.g. mail room, messengers, etc.), execute an agreement, in a form or
       forms previously provided to the Company, regarding (i) the protection of
       proprietary information, (ii) the assignment to Parent (or an applicable
       subsidiary) of all Parent Intellectual Property Rights arising from
       services performed for Parent or any of its subsidiaries by such Persons,
       (iii) the ownership by Parent or one of its subsidiaries of all Parent
       Intellectual Property Rights arising from the services performed for
       Parent or one of its subsidiaries by such Persons and (iv) limitations on
       the individual's ability to solicit or hire Parent's or its subsidiaries'
       employees or consultants.

       highly compensated employees, including base salary and bonuses, (the
       "Parent Key Employees"), other than those that are terminable by Parent
       or any of its subsidiaries on no more than thirty (30) days notice
       without liability or financial obligation or benefits generally available
       to employees of Parent, except to the extent general principles of
       wrongful termination law may limit Parent's or any of its subsidiaries'
       ability to terminate employees at will;

          (iii) any agreement or plan, including, without limitation, any stock
       option plan, stock appreciation right plan or stock purchase plan, any of
       the benefits of which will be increased, or the vesting of benefits of
       which will be accelerated, by the occurrence of any of the transactions

       subsidiaries and any of its officers or directors in standard forms as
       filed by Parent with the SEC;

           (v) any agreement, contract or commitment containing any covenant
       limiting the freedom of Parent or any of its subsidiaries to engage in
       any line of business or conduct business in any geographical area,
       compete with any person or granting any exclusive distribution rights;

       subsidiary with any other Person;

          (vii) any contract for capital expenditures in excess of $1,000,000;

         (viii) any agreement, contract or commitment currently in force
       relating to the disposition or acquisition of assets not in the ordinary
       course of business;

           (ix) any agreement, contract or commitment for the purchase of any
       ownership interest in any corporation, partnership, joint venture or
       other business enterprise for consideration in excess of $2,500,000, in
       any case which includes all escrow and earn-out agreements with
       outstanding obligations; or

           (x) any material joint marketing, distribution or development
       agreement or any other material contract of the Parent or any of its
       subsidiaries not previously filed with the SEC and not otherwise listed
       in any other section of the Parent Disclosure Schedule.

    A true and complete copy (including all amendments) of each Parent Contract
(or if standard forms are used, copies of the applicable forms with an
indication of any material differences from the actual listed Parent Contract),
or a summary of each oral contract, has been made available to the Company,
excluding those Parent Contracts referenced in clause (vii). Each contract set
forth in Section 5.1(o)(i)-(x) of the Parent Disclosure Schedule (a "Parent
Contract") and each Parent Material Contract (as defined below) is in full force
and effect, and is a legal, valid and binding obligation of Parent or a
subsidiary of Parent and, to the knowledge of Parent, each of the other parties
thereto, enforceable in accordance with

                                      A-14
<PAGE>
its terms, except (a) that the enforcement thereof may be limited by
(i) bankruptcy, insolvency, reorganization, moratorium or other similar laws now
or hereafter in effect relating to creditors' rights generally and (ii) general
principles of equity (regardless of whether enforceability is considered in a
proceeding in equity or at law) and (b) as would not, individually or in the
aggregate, be reasonably expected to result in a Material Adverse Effect on
Parent. No condition exists or event has occurred which (whether with or without
notice or lapse of time or both, or the happening or occurrence of any other
event) would constitute a default by Parent or a subsidiary of Parent or, to the
knowledge of Parent, any other party thereto under, or result in a right in
termination of, any Parent Contract or Parent Material Contract, except as would
not, individually or in the aggregate, be reasonably expected to result in a
Material Adverse Effect on Parent. The term "Parent Material Contract" shall
mean any contract that is material to Parent and its subsidiaries, taken as a
whole. Except as provided for herein, at the Effective Time, no Person will have
the right, by contract or otherwise, to become, nor does any entity have the
right to designate or cause Parent to appoint a Person as, a director of Parent
or any subsidiary of Parent.

        (p)  UNLAWFUL PAYMENTS AND CONTRIBUTIONS.  To the knowledge of Parent,

    of Parent or its subsidiaries, (i) used any funds for any unlawful
    contribution, endorsement, gift, entertainment or other unlawful expense
    relating to political activity; (ii) made any direct or indirect unlawful
    payment to any foreign or domestic government official or employee;
    (iii) violated or is in violation of any provision of the Foreign Corrupt

    operations, assets and properties thereof are in material compliance with
    all Environmental Laws; (ii) there are no judicial or administrative
    actions, suits, proceedings or investigations pending or, to the knowledge
    of Parent, threatened against Parent or any subsidiary of Parent alleging

    of Parent has received notice from any governmental body or Person alleging
    any violation of or liability under any Environmental Laws, in either case
    which could reasonably be expected to result in material Environmental Costs
    and Liabilities; (iii) to the knowledge of Parent, there are no facts,
    circumstances or conditions relating to, arising from, associated with or
    attributable to Parent or its subsidiaries or any real property currently or
    previously owned, operated or leased by Parent or its subsidiaries that
    could reasonably be expected to result in material Environmental Costs and
    Liabilities; and (iv) to the knowledge of Parent, neither Parent nor any of
    its subsidiaries has ever generated, transported, treated, stored, handled
    or disposed of any Hazardous Material (as hereinafter defined) at any site,
    location or facility in a manner that could create any material
    Environmental Costs and Liabilities under any Environmental Law, and no such
    Hazardous Material has been or is currently present on, in, at or under any
    real property owned or used by Parent or any of its subsidiaries in a manner
    that could create any Environmental Costs and Liabilities (including without
    limitation, containment by means of any underground or aboveground storage
    tank). For the purpose of Sections 5.1(s) and 5.2(s), the following terms
    have the following definitions: (X) "Environmental Costs and Liabilities"

       a valid leasehold interest in, the real and personal property, located on
       their premises or shown on their most recent balance sheet or acquired
       after the date thereof. None of the property owned or used by Parent or
       any of its subsidiaries is subject to any mortgage, pledge, deed of
       trust, lien (other than for taxes not yet due and payable), conditional
       sale agreement, security title, encumbrance, or other adverse claim or
       interest of any kind. Since September 30, 1999, there has not been any
       sale, lease, or any other disposition or distribution by Parent or any of

       leases, subleases, rental agreements, contracts of sale, tenancies or
       licenses related to any of the real property used by Parent or any of its
       subsidiaries in their respective businesses. All such leases are valid,
       binding and enforceable in accordance with their terms against the
       parties thereto, and each such lease is subsisting and no default exists
       under any thereof. Neither Parent nor any of its subsidiaries has
       received notice that any party to any such lease intends to cancel,
       terminate or refuse to renew the same or to exercise or decline to
       exercise any option or any right thereunder.

       payments or benefits upon the change of control of Parent (including,
       without limitation, any contract to which Parent is a party involving
       employees of Parent).

           (ii) Except as required by applicable law in non-U.S. jurisdictions,
       (A) none of the employees of Parent or any of its subsidiaries is
       represented in his or her capacity as an employee of such company by any
       labor organization; (B) neither Parent nor any of its subsidiaries has
       recognized any labor organization nor has any labor organization been
       elected as the collective bargaining agent of any of their employees, nor

       agreement or union contract recognizing any labor organization as the
       bargaining agent of any of their employees; and (C) to the knowledge of
       Parent there is no active or current union organization activity
       involving the employees of Parent or any of its subsidiaries, nor has
       there ever been union representation involving employees of Parent or any
       of its subsidiaries.

          (iii) Except for complaints which, in the aggregate, do not represent
       claims which could reasonably involve liabilities in excess of
       $2,000,000, there are no complaints against Parent or any of its
       subsidiaries pending or, to the knowledge of Parent, overtly threatened
       before the National Labor Relations Board or any similar foreign, state
       or local labor agencies, or before the Equal Employment Opportunity
       Commission or any similar foreign, state or local agency, or before any
       other governmental agency or entity by or on behalf of any employee or
       former employee of Parent or any of its subsidiaries.

       employment policies under which Parent and each subsidiary is operating.

           (v) Parent and each of its subsidiaries is in compliance with all
       Federal, foreign (as applicable), and state laws regarding employment
       practices, including laws relating to workers' safety, sexual harassment
       or discrimination, except where the failure to so be in compliance,
       individually or in the aggregate, would not have a Material Adverse
       Effect on Parent.

           (vi) To the knowledge of Parent, as of the date hereof, no executive,
       key employee or group of employees has any plans to terminate his or her
       employment with Parent or any of its subsidiaries.

        (u)  PERMITS.  Parent and each of its subsidiaries hold all licenses,
    permits, registrations, orders, authorizations, approvals and franchises
    which are required to permit it to conduct its businesses as presently
    conducted, except where the failure to hold such licenses, permits,
    registrations, orders, authorizations, approvals or franchises would not,
    individually or in the aggregate, have a Material Adverse Effect on Parent.
    All such material licenses, permits, registrations, orders, authorizations,
    approvals and franchises are now, and will be after the Closing, valid and
    in full force and effect, and Parent shall have full benefit of the same,
    except where the failure to be valid and in full force and effect or to have
    the benefit of any such license, permit, registration, order, authorization,
    approval or franchise would not, individually or in the aggregate, have a
    Material Adverse Effect on Parent. Neither Parent nor any of its
    subsidiaries has received any notification of any asserted present failure
    (or past and unremedied failure) by it to have obtained any such license,
    permit, registration, order, authorization, approval or franchise except
    where such failures would not, in the aggregate, have a Material Adverse
    Effect on Parent.

        (v)  WARRANTY OR OTHER CLAIMS.  Parent has provided to the Company a
    copy of its standard form agreement for services. It is Parent's practice
    and policy to adhere to the form terms, except to the extent not
    commercially practicable.

        (w)  TRANSACTIONS WITH AFFILIATES.  Except as set forth in the Parent
    SEC Reports filed prior to the date of this Agreement, since the date of
    Parent's last proxy statement to its stockholders, no event has occurred
    that would be required to be reported by Parent as a Certain Relationship or
    Related Transaction, pursuant to Item 404 of Regulation S-K promulgated by
    the SEC.

        (x)  COMPUTER SOFTWARE.  The occurrence in or use by any material
    Software used by Parent and its subsidiaries of dates on or after
    January 1, 2000 will not result in any Malfunction.

    all necessary action so that the restrictions contained in Section 203 of
    the DGCL applicable to a "business combination" (as defined in Section 203)
    will not apply to the execution, delivery or performance of this Agreement
    or the Stockholder Agreements or the consummation of the Merger or the other
    transactions contemplated by this Agreement or the Stockholder Agreements.
    No other state takeover statute or similar statute or regulation is
    applicable to this Agreement or the Stockholder Agreements.

    5.2  REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company hereby
represents and warrants to Parent and Merger Sub that the statements contained
in this Section 5.2 are true and correct, except to the extent specifically set
forth on the disclosure schedule previously delivered by the Company to Parent
and Merger Sub (the "Company Disclosure Schedule"). The Company Disclosure
Schedule shall be arranged in sections and paragraphs corresponding to the
letter and numbered paragraphs contained in this Section 5.2, and the disclosure
in any paragraph shall qualify only the corresponding paragraph in this Section
5.2 or other paragraphs or sections to which it is clearly apparent (from a
plain reading of the disclosure) that such disclosure relates.

        (a)  CORPORATE ORGANIZATION AND QUALIFICATION.  Each of the Company and
    its subsidiaries is a corporation duly organized, validly existing and in
    good standing under the laws of the jurisdiction of incorporation and is
    qualified and in good standing as a foreign corporation in each jurisdiction
    where the properties owned, leased or operated, or the business conducted,
    by it require such qualification, except where failure to so qualify or be
    in good standing as a foreign corporation would not have a Material Adverse
    Effect on the Company. Each of the Company and its subsidiaries has all
    requisite power and authority (corporate or otherwise) to own its properties
    and to carry on its business as it is now being conducted. All of the
    subsidiaries of the Company are set forth in Section 5.2(a) of the Company
    Disclosure Schedule. The Company has heretofore made available to Parent
    complete and correct copies of its Certificate of Incorporation and Bylaws
    and the charter documents of its subsidiaries, each as amended.

        (b)  CAPITALIZATION.  The authorized capital stock of the Company
    consists of (i) 200,000,000 shares of common stock, $0.001 par value per
    share, of which 90,645,130 shares were issued and outstanding on
    November 30, 1999, and (ii) 1,000,000 shares of preferred stock, $0.001 par
    value per share, none of which is issued or outstanding. All of the

    Plan, the 1997 Acquisition Stock Option Plan and the 1999 Non-Qualified
    Stock Option Plan of the Company (the "Company Stock Option Plans"),
    (ii) existing as a result of the Company's assumption of then outstanding
    stock options of CKS Group, Inc. in connection with the merger with CKS
    Group, Inc. consummated on December 17, 1998, and (iii) under the Stock
    Option Agreement with Robert Shaw and the Company's Bonus Plan (the plans
    and agreements referred to in clauses (i), (ii) and (iii), collectively, the
    "Company Option Plans") and rights under the Company ESPPs, as of
    November 30, 1999, there are no outstanding or authorized options, warrants,
    calls, rights (including preemptive rights), commitments or any other
    agreements of any character which the Company or any of its subsidiaries is
    a party to, or may be bound by, requiring it to issue, transfer, grant,
    sell, purchase, redeem or acquire any shares of capital stock or any of its
    securities or rights convertible into, exchangeable for, or evidencing the
    right to subscribe for, any shares of capital stock of the Company or any of
    its subsidiaries. There are not as of the date hereof and there will not be
    at the Effective Time any stockholder agreements, voting trusts or other
    agreements or understandings to which the Company is a party or to which it
    is bound relating to the voting of any shares of the capital stock of the
    Company. No existing rights with respect to the registration of Company
    Shares under the Securities Act, including, but not limited to, demand
    rights or piggy-back registration rights, shall apply with respect to any
    Parent Shares issuable in connection with the Merger. The Company has
    provided to Parent a list, as of November 30, 1999, of the outstanding
    options to acquire shares of the Company's capital stock, the name of the
    holder of such option, the exercise price of such option, the number of
    shares as to which such option will have vested at such date and whether the
    exercisability of such option will be accelerated in any way by the
    transactions contemplated by this Agreement, and indicates the extent of
    acceleration, if any. Since November 30, 1999 through the date hereof no
    options have been issued or accelerated or had their terms modified.

        (c)  FAIRNESS OPINION.  The Board of Directors of the Company has
    received an oral opinion from Morgan Stanley Dean Witter to be confirmed in
    writing and addressed to its Board of Directors, to the effect that, as of
    the date hereof and based upon and subject to the matters stated therein,
    the consideration to be received by the holders of Common Shares in the
    Merger is fair to such holders from a financial point of view. As of the
    date hereof, such opinion has not been withdrawn, revoked or modified.

        (d)  AUTHORITY RELATIVE TO THIS AGREEMENT.  The Board of Directors of
    the Company has declared the Merger advisable and the Company has the
    requisite corporate power and authority to approve, authorize, execute and
    deliver this Agreement and to consummate the transactions contemplated
    hereby. This Agreement and the consummation by the Company of the
    transactions contemplated hereby have been duly and validly authorized by

    consummate the transactions contemplated hereby (other than the approval of
    the Merger by the stockholders of the Company in accordance with the DGCL).
    This Agreement has been duly and validly executed and delivered by the
    Company and, assuming this Agreement constitutes the valid and binding

    Company, enforceable against the Company in accordance with its terms,
    subject, as to enforceability, to bankruptcy, insolvency, reorganization and
    other laws of general applicability relating to or affecting creditors'
    rights and to general principles of equity.

        (e)  PRESENT COMPLIANCE WITH OBLIGATIONS AND LAWS.  Neither the Company
    nor any of its subsidiaries is: (i) in violation of its Certificate of
    Incorporation or Bylaws or similar documents; (ii) in default in the

    affords to any Person the right to accelerate any indebtedness or terminate
    any right; (iii) in default under or breach of (with or without the passage
    of time or the giving of notice) any other contract to which it is a party
    or by which it or its assets are bound; or (iv) in violation of any law,
    regulation, administrative order or judicial order, decree or judgment
    (domestic or foreign) applicable to it or its business or assets, except
    where any violation, default or breach under items (ii), (iii), or
    (iv) would not, individually or in the aggregate, have a Material Adverse
    Effect on the Company.

        (f)  CONSENTS AND APPROVALS; NO VIOLATION.  Neither the execution and
    delivery of this Agreement by the Company nor the consummation by the
    Company of the transactions contemplated hereby will (i) conflict with or
    result in any breach of any provision of its Certificate of Incorporation or
    Bylaws; (ii) require any consent, approval, authorization or permit of, or
    registration or filing with or notification to, any governmental or
    regulatory authority, except (A) in connection with the applicable
    requirements, if any, of the HSR Act, (B) pursuant to the applicable
    requirements of the Securities Act and the Exchange Act, (C) the filing of
    the Certificate of Merger pursuant to the DGCL and appropriate documents
    with the relevant authorities of other states in which the Company is
    authorized to do business, (D) as may be required by any applicable state
    securities laws, (E) such filings, consents, approvals, orders,
    authorizations, registrations, declarations and filings as may be required
    under the antitrust laws of any foreign country or, (F) where the failure to
    obtain such consent, approval, authorization or permit, or to make such
    filing or notification, would not in the aggregate have a Material Adverse
    Effect on the Company or adversely affect the ability of the Company to
    consummate the transactions contemplated hereby; (iii) result in a violation
    or breach of, or constitute (with or without notice or lapse of time or
    both) a default (or give rise to any right of termination, cancellation or
    acceleration or lien or other charge or encumbrance) under any of the terms,
    conditions or provisions of any indenture, note, license, lease, agreement
    or other instrument or obligation to which the Company or any of its
    subsidiaries is a party or by which any of their assets may be bound, except
    for such violations, breaches and defaults (or rights of termination,
    cancellation, or acceleration or lien or other charge or encumbrance) as to
    which requisite waivers or consents have been obtained or which, in the
    aggregate, would not have a Material Adverse Effect on the Company or
    adversely affect the ability of the Company to consummate the transactions
    contemplated hereby; (iv) cause the suspension or revocation of any
    authorizations, consents, approvals or licenses currently in effect which
    would have a Material Adverse Effect on the Company; or (v) assuming the

    referred to in this Section 5.2(f) are duly and timely obtained or made,
    violate any order, writ, injunction, decree, statute, rule or regulation
    applicable to the Company or any of its subsidiaries or to any of their
    respective assets, except for violations which would not in the aggregate
    have a Material Adverse Effect on the Company or adversely affect the
    ability of the Company to consummate the transactions contemplated hereby.

        (g)  LITIGATION.  Except as disclosed in Company SEC Reports filed prior
    to the date hereof, there are no actions, suits, claims, investigations or
    proceedings pending or, to the knowledge of the Company, threatened against
    the Company or any of its subsidiaries that, alone or in the aggregate,
    would be reasonably likely to result in obligations or liabilities of the
    Company or any of its subsidiaries that would have a Material Adverse Effect
    on the Company or a material adverse effect on the parties' ability to
    consummate the transactions contemplated by this Agreement. Neither the

                                      A-19
<PAGE>
    Company nor any of its subsidiaries is subject to any outstanding order,
    writ, injunction or decree which (i) has or may have the effect of
    prohibiting or impairing any business practice of the Company or any of its
    subsidiaries, any acquisition of property (tangible or intangible) by the
    Company or any of its subsidiaries, the conduct of the business by the
    Company or any of its subsidiaries, or Company's ability to perform its
    obligations under this Agreement or (ii), insofar as can be reasonably
    foreseen, individually or in the aggregate, would have a Material Adverse
    Effect on the Company.

        (h)  SEC REPORTS; FINANCIAL STATEMENTS.

           (i) Since January 1, 1997, the Company has filed all forms, reports
       and documents with the SEC required to be filed by it pursuant to the
       federal securities laws and the SEC rules and regulations thereunder, all
       of which complied in all material respects with all applicable
       requirements of the Securities Act and the Exchange Act (the "Company SEC
       Reports"). None of the Company SEC Reports, including, without
       limitation, any financial statements or schedules included therein, at
       the time filed (or if amended or superseded by a filing prior to the date
       of this Agreement, then on the date of such filing) contained any untrue
       statement of a material fact or omitted to state a material fact required
       to be stated therein or necessary in order to make the statements
       therein, in light of the circumstances under which they were made, not
       misleading. None of the Company's subsidiaries is required to file any
       forms, reports or other documents with the SEC.

           (ii) The consolidated balance sheets and the related statements of
       income, stockholders' equity and cash flow (including the related notes
       thereto) of the Company included in the Company SEC Reports
       (collectively, the "Company Financial Statements") comply as to form in
       all material respects with applicable accounting requirements and the
       published rules and regulations of the SEC with respect thereto, have
       been prepared in accordance with generally accepted accounting principles
       applied on a basis consistent throughout the periods involved (except as
       otherwise noted therein or, in the case of unaudited interim financial
       statements, as may be permitted by the SEC on Form 10-Q under the
       Exchange Act), and present fairly the consolidated financial position of
       the Company and its consolidated subsidiaries as of their respective
       dates, and the results of its operations and its cash flow for the
       periods presented therein (subject, in the case of the unaudited interim
       financial statements, to normal and recurring year-end adjustments).
       Since January 1, 1999, there has not been any material change, by the
       Company or any of its subsidiaries in accounting principles, methods or
       policies for financial accounting purposes except as required by
       concurrent changes in generally accepted accounting principles.

        (i)  NO LIABILITIES; ABSENCE OF CERTAIN CHANGES OR EVENTS.  Neither the
    Company nor any of its subsidiaries has any material indebtedness,
    obligations or liabilities of any kind (whether accrued, absolute,
    contingent or otherwise, and whether due or to become due or asserted or
    unasserted), and, to the knowledge of the Company, there is no reasonable
    basis for the assertion of any material claim or liability of any nature
    against the Company or any of its subsidiaries, except for liabilities
    (i) which are fully reflected in, reserved against or otherwise described in
    the Company Financial Statements for the period ending September 30, 1999,
    (ii) which have been incurred after September 30, 1999 in the ordinary
    course of business, consistent with past practice, or (iii) which are
    obligations to perform under executory contracts in the ordinary course of
    business (none of which is a liability resulting from a breach of contract
    or warranty, tort, infringement or legal action). Since September 30, 1999,
    the business of the Company and its subsidiaries has been carried on only in
    the ordinary and usual course, and there has not been any Material Adverse
    Effect on the Company and no event has occurred and no fact or set of
    circumstances has arisen which has resulted in or could reasonably be
    expected to result in a Material Adverse Effect on the Company. Since
    September 30, 1999, to the knowledge of the Company, no material customer or
    supplier of the Company or its subsidiaries has threatened, in writing, to
    alter materially its relationship with the Company or its subsidiaries.
    Since

                                      A-20
<PAGE>
    September 30, 1999, neither the Company nor any of its subsidiaries has
    agreed to a waiver or release of any material right or claim (including
    without limitation to any write off or other compromise of any material
    account receivable) outside of the ordinary course of business consistent
    with past practice.

        (j)  BROKERS AND FINDERS.  Except for the fees and expenses payable to
    Morgan Stanley Dean Witter, which fees and expenses are reflected in its
    agreement with the Company, a true and complete copy of which (including all
    amendments) has been furnished to the Company, neither the Company nor any
    of its subsidiaries has employed any investment banker, broker, finder,
    consultant or intermediary in connection with the transactions contemplated
    by this Agreement which would be entitled to any investment banking,
    brokerage, finder's or similar fee or commission in connection with this
    Agreement or the transactions contemplated hereby.

        (k)  S-4 REGISTRATION STATEMENT AND PROXY STATEMENT/PROSPECTUS.  None of
    the information supplied or to be supplied by the Company for inclusion or
    incorporation by reference in the S-4 Registration Statement or the Joint
    Proxy Statement will (i) in the case of the S-4 Registration Statement, at
    the time it becomes effective or at the Effective Time, contain any untrue
    statement of a material fact or omit to state any material fact required to
    be stated therein or necessary in order to make the statements therein not
    misleading, or (ii) in the case of the Joint Proxy Statement, at the time of
    the mailing of the Joint Proxy Statement and at the time of the Stockholder
    Meetings, contain any untrue statement of a material fact or omit to state
    any material fact required to be stated therein or necessary in order to
    make the statements therein, in light of the circumstances under which they
    are made, not misleading. If at any time prior to the Effective Time any
    event with respect to the Company, its officers and directors or any of its
    subsidiaries should occur which is required to be described in an amendment
    of, or a supplement to, the Joint Proxy Statement or the S-4 Registration
    Statement, the Company shall promptly inform Parent such event shall be so
    described, and such amendment or supplement shall be promptly filed with the
    SEC and, as required by law, disseminated to the stockholders of the Company
    and Parent. The S-4 Registration Statement will (with respect to the
    Company) comply as to form in all material respects with the requirements of
    the Securities Act and the rules and regulations promulgated thereunder. The
    Joint Proxy Statement will (with respect to the Company) comply as to form
    in all material respects with the requirements of the Exchange Act and the
    rules and regulations promulgated thereunder.

        (l)  TAXES.

           (i) The Company and each of its subsidiaries has timely filed all
       Returns required by applicable Tax law to be filed by the Company and
       each of its subsidiaries, except for any such failures to file that could
       not reasonably be expected to have, individually or in the aggregate, a
       Material Adverse Effect on the Company. All Taxes owed by the Company or
       any of its subsidiaries to a taxing authority, or for which the Company
       or any of its subsidiaries is liable, whether to a taxing authority or to
       other Persons or entities under a Significant Tax Agreement, as of the
       date hereof, have been paid and, as of the Effective Time, will have been
       paid, except for any such failure to pay that could not reasonably be
       expected to have, individually or in the aggregate, a Material Adverse
       Effect on the Company. The Company has made accruals for Taxes on the
       Company Financial Statements which are adequate to cover any Tax
       liability of the Company and each of its subsidiaries determined in
       accordance with generally accepted accounting principles through the date
       of the Company Financial Statements, except where failures to make such
       accruals or provisions could not reasonably be expected to have,
       individually or in the aggregate, a Material Adverse Effect on the
       Company.

           (ii) Except to the extent that any such failure to withhold could not
       reasonably be expected to have, individually or in the aggregate, a
       Material Adverse Effect on the Company, the

                                      A-21
<PAGE>
       Company and each of its subsidiaries have withheld with respect to its
       employees all federal and state income taxes, FICA, FUTA and other Taxes
       required to be withheld.

          (iii) There is no Tax deficiency outstanding, proposed or assessed
       against the Company or any of its subsidiaries, except any such
       deficiency that, if paid, could not reasonably be expected to have,
       individually or in the aggregate, a Material Adverse Effect on the
       Company. Neither the Company nor any of its subsidiaries executed or
       requested any waiver of any statute of limitations on or extending the
       period for the assessment or collection of any federal or material state
       Tax that is still in effect.

          (iv) No federal or state Tax audit or other examination of the Company
       or any of its subsidiaries is presently in progress, nor has the Company
       or any of its subsidiaries been notified in writing of any request for
       such federal or material state Tax audit or other examination, except in
       all cases for Tax audits and other examinations which could not
       reasonably be expected to have, individually or in the aggregate, a
       Material Adverse Effect on the Company.

           (v) Neither the Company nor any of its subsidiaries has filed any
       consent agreement under Section 341(f) of the Code or agreed to have
       Section 341(f)(2) of the Code apply to any disposition of a subsection
       (f) asset (as defined in Section 341(f)(4) of the Code) owned by the
       Company.

           (vi) Neither the Company nor any of its subsidiaries is a party to
       (A) any agreement with a party other than the Company or any of its
       subsidiaries providing for the allocation or payment of Tax liabilities
       or payment for Tax benefits with respect to a consolidated, combined or
       unitary Return which Return includes or included the Company or any
       subsidiary or (B) any Significant Tax Agreement other than any
       Significant Tax Agreement described in (A).

          (vii) Except for the group of which the Company and its subsidiaries
       are now presently members, neither the Company nor any of its
       subsidiaries has ever been a member of an affiliated group of
       corporations within the meaning of Section 1504 of the Code.

         (viii) Neither the Company nor any of its subsidiaries has agreed to
       make nor is it required to make any adjustment under Section 481(a) of
       the Code by reason of a change in accounting method or otherwise which
       have not yet been taken into account.

           (ix) The Company is not, and has not at any time been, a United
       States Real Property Holding Corporation.

        (m)  EMPLOYEE BENEFITS.

           (i) Section 5.2(m)(i) of the Company Disclosure Schedule lists each

       agreement, retainer agreement, or any other material benefit plan,
       policy, program, arrangement, agreement or contract, whether or not
       written or terminated, with respect to any employee, former employee,
       director, independent contractor, or any beneficiary or dependent thereof
       maintained, sponsored, adopted or administered by the Company or any
       current or former Plan Affiliate or to which the Company or any current
       or former Plan Affiliate has made contributions to, obligated itself or
       had any

                                      A-22
<PAGE>
       liability with respect to (all such plans, policies, programs,
       arrangements, agreements and contracts, are referred to in this Agreement
       as "Company Scheduled Plans").

           (ii) The Company has delivered or made available to Parent a complete
       and accurate copy, as of the Closing, of each written Company Scheduled
       Plan, together with, if applicable, a copy of audited financial
       statements, actuarial reports and Form 5500 Annual Reports (including
       required schedules), if any, for the three (3) most recent plan years,
       the most recent IRS determination letter or IRS recognition of exemption;
       each other material letter, ruling or notice issued by a governmental
       body with respect to each such plan, a copy of each trust agreement,
       insurance contract or other funding vehicle, if any, with respect to each
       such plan, the most recent PBGC Form 1 with respect to each such plan, if
       any, the current summary plan description and summary of material
       modifications thereto with respect to each such plan, Form 5310 and any

       years, for each Plan subject to Title IV of ERISA, general notification
       to employees of their rights under Code Section 4980B and form of
       letter(s) distributed upon the occurrence of a qualifying event described
       in Code Section 4980B, in the case of a Company Scheduled Plan that is a
       "group health plan" as defined in Code Section 162(i), and a copy or
       description of each other general explanation or written or oral
       communication which describes a material term of each Company Scheduled
       Plan that has not previously been disclosed to Parent pursuant to this
       Section. Section 5.2(m) of the Company Disclosure Schedule contains a
       description of the material terms of any unwritten Company Scheduled Plan
       as comprehended to the Closing Date. Except as set forth in
       Section 5.2(m) of the Company Disclosure Schedule, there are no
       negotiations, demands or proposals which are pending or threatened which
       concern matters now covered, or that would be covered, by the foregoing
       types of unwritten Plans.

          (iii) Except as could not reasonably give rise, whether individually
       or in the aggregate, to a Material Adverse Effect to the Company, Parent,
       or Merger Sub:

               (1) Each Company Scheduled Plan (A) has been and currently
           complies in form and in operation in all material respects with all
           applicable requirements of ERISA and the Code, and any other legal
           requirements; (B) has been and is operated and administered in
           material compliance with its terms (except as otherwise required by
           law); (C) has been and is operated in compliance with applicable
           legal requirements in such a manner as to qualify, where appropriate,
           for both Federal and state purposes, for income tax exclusions to its
           participants, tax-exempt income for its funding vehicle, and the
           allowance of deductions and credits with respect to contributions
           thereto; and (D) where appropriate, has received a favorable
           determination letter or recognition of exemption from the Internal
           Revenue Service.

               (2) With respect to each Company Scheduled Plan, there are no
           claims or other proceedings pending or, to the knowledge of the
           Company, threatened with respect to the assets thereof (other than
           routine claims for benefits), and there are no facts which could
           reasonably give rise to any material liability, claim or other
           proceeding against any Company Scheduled Plan, any fiduciary or plan
           administrator or other Person dealing with any Company Scheduled Plan
           or the assets of any such Company Scheduled Plan.

               (3) With respect to each Company Scheduled Plan, to the knowledge
           of the Company, no Person: (A) has entered into any "prohibited
           transaction," as such term is defined in ERISA or the Code and the
           regulations, administrative rulings and case law thereunder that is
           not otherwise exempt under Code Section 4975 or ERISA Section 408 (or
           any administrative class exemption issued thereunder); (B) has
           materially breached a fiduciary obligation or violated Sections 402,
           403, 405, 503, 510 or 511 of ERISA; (C) has any material liability
           for any failure to act or comply in connection with the
           administration or investment of the assets

                                      A-23
<PAGE>
           of such plans; or (D) engaged in any transaction or otherwise acted
           with respect to such plans in such a manner which could subject
           Parent, or any fiduciary or plan administrator or any other Person
           dealing with any such plan, to material liability under Section 409
           or 502 of ERISA or Sections 4972 or 4976 through 4980B of the Code.

               (4) Each Company Scheduled Plan (other than any stock option
           plan) may be amended, terminated, modified or otherwise revised by
           the Company or Parent, on and after the Closing, without further
           material liability to the Company or Parent (other than ordinary
           administrative expenses or routine claims for benefit plans),
           including, but not limited to, any withdrawal liability under ERISA
           for any multi-employer plan or any liability under any Company
           Scheduled Plan subject to Title IV of ERISA.

               (5) None of the Company or any current or former Company Plan
           Affiliate has at any time participated in, made contributions to or
           had any other liability with respect to any Company Scheduled Plan
           which is a "multi-employer plan" as defined in Section 4001 of ERISA,
           a "multi-employer plan" within the meaning of Section 3(37) of ERISA,
           a "multiple employer plan" within the meaning of Section 413(c) of
           the Code, a "multiple employer welfare arrangement" within the
           meaning of Section 3(40) of ERISA or a plan that is subject to Title
           IV of ERISA.

               (6) No Company Scheduled Plan provides, or reflects or represents
           any liability to provide retiree health to any person for any reason,
           except as may be required by COBRA or other applicable statute, and
           neither the Company nor any Plan Affiliate has ever represented,
           promised or contracted (whether in oral or written form) to any
           current or former employee, consultant or director (either
           individually or as a group) or any other person that such current or
           former employee(s) or other person would be provided with retiree
           health, except to the extent required by applicable continuation
           coverage statute.

               (7) No Company Scheduled Plan has incurred an "accumulated
           funding deficiency" as such term is defined in Section 302 of ERISA
           or Section 412 of the Code, whether or not waived, or has posted or
           is required to provide security under Code Section 401(a)(29) or
           Section 307 of ERISA; no event has occurred which has or could result

           Sections 4971, 4972, 4977, or 4979, or (E) for any minimum funding
           contributions under Section 302(c)(11) of ERISA or Code
           Section 412(c)(11).

               (11) All the Company Scheduled Plans to the extent applicable,
           are in compliance with Section 1862(b)(1)(A)(i) of the Social

           welfare plan as defined in Section 3(1) of ERISA; (A) each such
           welfare plan which is intended to meet the requirements for
           tax-favored treatment under Subchapter B of Chapter 1 of the Code
           materially meets such requirements; and (B) there is no disqualified
           benefit (as such term is defined in Code Section 4976(b)) which would
           subject the Company or any Plan Affiliate to a tax under Code
           Section 4976(a).

               (13) Each Company Scheduled Plan that has been adopted or
           maintained by the Company or any Plan Affiliate, whether informally
           or formally, or with respect to which the Company or any Plan

           statutory or regulatory laws that are applicable to such Company
           International Employee Plan. Furthermore, no Company International
           Employee Plan has unfunded liabilities, that, as of the Effective
           Time, will not be offset by insurance or fully accrued. Except as
           required by law, no condition exists that would prevent the Company
           or any Plan Affiliate from terminating or amending any Company
           International Employee Plan at any time for any reason without
           material liability to the Company or any Plan Affiliate (other than
           ordinary administration expenses or routine claims for benefits). To
           the extent any such Company International Employee Plan has not been
           disclosed or provided prior to the date of this Agreement, the
           Company agrees to use its best efforts to disclose and provide such
           plan prior to the Effective Time.

           (iv) Other than by reason of actions taken by Parent following the
       Closing, the consummation of the transactions contemplated by this
       Agreement will not (A) entitle any current or former employee of the
       Company to severance pay, unemployment compensation or any other payment,
       (B) accelerate the time of payment or vesting of any payment (other than
       for a terminated or frozen tax-qualified plan, pursuant to a requirement
       herein to freeze or terminate such plan), cause the forgiveness of any
       indebtedness, or increase the amount of any compensation due to any such
       employee or former employee, (C) result in any prohibited transaction
       described in Section 406 of ERISA or Section 4975 of the Code for which
       an exemption is not available, or (D) give rise to the payment of any
       amount that would not be deductible pursuant to the terms of

       notice or lapse of time or both, or the happening or occurrence of any
       other event) would constitute a default by the Company or a subsidiary of
       the Company or, to the knowledge of the Company, any other party thereto
       under, or result in a right in termination of, any Company Contract or
       Company Material Contract, except as would not, individually or in the
       aggregate, be reasonably expected to result in a Material Adverse Effect
       on the Company. The term "Company Material Contract" shall mean any
       contract that is material to the Company and its subsidiaries, taken as a
       whole.

    actions, suits, proceedings or investigations pending or, to the knowledge
    of the Company, threatened against the Company or any subsidiary of the
    Company alleging the violation of any Environmental Law and neither the

    governmental body or Person alleging any violation of or liability under any
    Environmental Laws, in either case which could reasonably be expected to
    result in material Environmental Costs and Liabilities; (iii) to the
    knowledge of the Company, there are no facts, circumstances or conditions
    relating to, arising from, associated with or attributable to the Company or
    its subsidiaries or any real property currently or previously owned,
    operated or leased by the Company or its subsidiaries that could reasonably

    (iv) to the knowledge of the Company, neither the Company nor any of its
    subsidiaries has ever generated, transported, treated, stored, handled or
    disposed of any Hazardous Material at any site, location or facility in a
    manner that could create any material Environmental Costs and Liabilities
    under any Environmental Law, and no such Hazardous Material has been or is
    currently present on, in, at or under any real property owned or used by the
    Company or any of its subsidiaries in a manner that could create any
    Environmental Costs and Liabilities (including without limitation,
    containment by means of any underground or aboveground storage tank).

        (s)  TITLE TO PROPERTIES; LIENS; CONDITION OF PROPERTIES.

           (i) The Company and its subsidiaries have good and marketable title

       pledge, deed of trust, lien (other than for taxes not yet due and
       payable), conditional sale agreement, security title, encumbrance, or
       other adverse claim or interest of any kind. Since September 30, 1999,
       there has not been any sale, lease, or any other disposition or
       distribution by the Company or any of its subsidiaries of any of its
       assets or properties material to the Company and its subsidiaries, taken
       as a whole, except transactions in the ordinary and regular course of
       business.

           (ii) The Company has delivered to Parent a schedule of all material
       leases, subleases, rental agreements, contracts of sale, tenancies or
       licenses related to any of the real property used by the Company or any
       of its subsidiaries in their respective businesses. All such leases are
       valid, binding and enforceable in accordance with their terms against the
       parties thereto, and each such lease is subsisting and no default exists
       under any thereof. Neither the Company nor any of its subsidiaries has
       received notice that any party to any such lease intends to cancel,
       terminate or refuse to renew the same or to exercise or decline to
       exercise any option or any right thereunder.

    franchises which are required to permit it to conduct its businesses as
    presently conducted, except where the failure to hold such licenses,
    permits, registrations, orders, authorizations, approvals or franchises

    cause each of their subsidiaries to, conduct their operations according to

<PAGE>
    (E) increase the total head count of Parent and its subsidiaries, or the
    Company and its subsidiaries, in an amount greater than an increase in the

    6.2  NO SOLICITATION BY THE COMPANY.

        (a) From and after the date of this Agreement until the Effective Time
    or the earlier termination of this Agreement in accordance with its terms,
    the Company and its subsidiaries will not, and will not permit their
    respective directors, officers, investment bankers, affiliates,
    representatives and agents to, (i) solicit, initiate, or encourage
    (including by way of furnishing information), or take any other action to
    facilitate, any inquiries or proposals that constitute, or could reasonably
    be expected to lead to, any Company Acquisition Proposal (as defined below),
    or (ii) engage in, or enter into, any negotiations or discussions concerning
    any Company Acquisition Proposal. Notwithstanding the foregoing, in the
    event that, notwithstanding compliance with the preceding sentence, the
    Company receives a Company Superior Proposal (as defined below) the Company
    may, to the extent that the Board of Directors of the Company determines in
    good faith (in consultation with outside counsel) that such action would, in
    the absence of the foregoing proscriptions, be required by its fiduciary
    duties, participate in discussions regarding any Company Superior Proposal
    in order to be informed with respect thereto in order to make any
    determination permitted pursuant to Section 6.2(b)(i). In such event, the
    Company shall, (i) no less than twenty four (24) hours prior to
    participating in any such discussions, inform Parent of the material terms
    and conditions of such Company Superior Proposal, including the identity of
    the Person making such Company Superior Proposal and (ii) promptly keep
    Parent informed of the status including any material change to the terms of
    any such Company Superior Proposal. As used herein, the term "Company
    Acquisition Proposal" shall mean any bona fide inquiry, proposal or offer
    relating to any (i) merger, consolidation, business combination, or similar
    transaction involving the Company or any subsidiary of the Company,
    (ii) sale, lease or other disposition, directly or indirectly, by merger,
    consolidation, share exchange or otherwise, of any assets of the Company or
    any subsidiary of the Company in one or more transactions, (iii) issuance,
    sale, or other disposition of (including by way of merger, consolidation,
    share exchange or any similar transaction) securities (or options, rights or
    warrants to purchase such securities, or securities convertible into such
    securities) of the Company or any subsidiary of the Company,
    (iv) liquidation, dissolution, recapitalization or other similar type of
    transaction with respect to the Company or any subsidiary of the Company,
    (v) tender offer or exchange offer for Company securities; in the case of
    (i), (ii), (iii), (iv) or (v) above, which transaction would result in a
    third party (or its shareholders) acquiring more than thirty-five percent
    (35%) of the voting power of the Company or the assets representing more
    than thirty-five percent (35%) of the net income, net revenue or assets of
    the Company on a consolidated basis, (vi) transaction which is similar in
    form, substance or purpose to any of the foregoing transactions or
    (vii) public announcement of an agreement, proposal, plan or intention to do
    any of the foregoing, PROVIDED, HOWEVER, that the term "Company Acquisition
    Proposal" shall not include the Merger and the transactions contemplated
    thereby. For purposes of this Agreement, "Company Superior Proposal" means
    any offer not solicited by the Company, or by other persons in violation of
    the first sentence of this Section 6.2(a), and made by a third party to
    consummate a tender offer, exchange offer, merger, consolidation or similar
    transaction which would result in such third party (or its shareholders)
    owning, directly or indirectly, more than fifty percent (50%) of the Company
    Shares then outstanding (or of the surviving entity in a merger) or all or
    substantially all of the assets of Company and its subsidiaries, taken
    together, and otherwise on terms which the Board of Directors of the Company
    determines in good faith (based on its consultation with a financial advisor
    of nationally recognized reputation and other such matters that it deems
    relevant) would, if consummated, result in a transaction more favorable to
    the Company's stockholders from a financial point of view than the Merger
    and, in the reasonable good faith judgment of the Board of Directors of the
    Company after consultation with its financial advisor the persons or entity
    making such Company Superior Proposal has the financial means to conclude

                                      A-33
<PAGE>
    such transaction. The Company will immediately cease any and all existing
    activities, discussions or negotiations with any parties conducted
    heretofore with respect to any of the foregoing.

        (b) Neither the Board of Directors of the Company nor any committee
    thereof shall (i) except as required by their fiduciary duties as determined
    in good faith in consultation with outside counsel, withdraw or modify, or
    propose to withdraw or modify, in a manner adverse to Parent or Merger Sub,
    the approval or recommendation by the Board of Directors of the Company or
    such committee of this Agreement or the Merger, (ii) approve, recommend, or
    otherwise support or endorse any Company Acquisition Proposal, or
    (iii) cause the Company to enter into any letter of intent, agreement in
    principle, acquisition agreement or similar agreement (each a "Company
    Acquisition Agreement") with respect to any Company Acquisition Proposal.
    Nothing contained in this Section 6.2 shall prohibit the Company from taking
    and disclosing to its stockholders a position contemplated by Rule 14d-9 or
    14e-2 promulgated under the Exchange Act or from making any disclosure to
    the Company's stockholders if, in the good faith judgment of the Board of
    Directors of the Company, in consultation with outside counsel, such
    disclosure is necessary for the Board of Directors to comply with its
    fiduciary duties under applicable law; PROVIDED, HOWEVER, that, subject to
    Section 6.2(b)(i), neither the Company nor its Board of Directors nor any
    committee thereof shall withdraw or modify, or propose publicly to withdraw
    or modify, its position with respect to this Agreement or the Merger or
    approve or recommend or propose publicly to approve or recommend, a Company
    Acquisition Proposal.

        (c) In addition to the obligations of the Company set forth in
    paragraphs (a) and (b) of this Section 6.2, the Company will promptly (and
    in any event within twenty-four (24) hours) advise Parent, orally and in
    writing, if any Company Acquisition Proposal is made or proposed to be made
    or any information or access to properties, books or records of the Company
    is requested in connection with a Company Acquisition Proposal, the
    principal terms and conditions of any such Company Acquisition Proposal or
    potential Company Acquisition Proposal or inquiry (and will disclose any
    written materials received by the Company in connection with such Company
    Acquisition Proposal, potential Company Acquisition Proposal or inquiry) and
    the identity of the party making such Company Acquisition Proposal,
    potential Company Acquisition Proposal or inquiry. The Company will keep
    Parent advised of the status and details (including amendments and proposed
    amendments) of any such request or Company Acquisition Proposal.

    6.3  NO SOLICITATION BY PARENT.

        (a) From and after the date of this Agreement until the Effective Time
    or the earlier termination of this Agreement in accordance with its terms,
    Parent and its subsidiaries will not, and will not permit their respective
    directors, officers, investment bankers, affiliates, representatives and
    agents to, (i) solicit, initiate, or encourage (including by way of
    furnishing information), or take any other action to facilitate, any
    inquiries or proposals that constitute, or could reasonably be expected to
    lead to, any Parent Acquisition Proposal (as defined below), or (ii) engage
    in, or enter into, any negotiations or discussions concerning any Parent
    Acquisition Proposal. Notwithstanding the foregoing, in the event that,
    notwithstanding compliance with the preceding sentence, Parent receives a
    Parent Superior Proposal (as defined below) Parent may, to the extent that
    the Board of Directors of Parent determines in good faith (in consultation
    with outside counsel) that such action would, in the absence of the
    foregoing proscriptions, be required by its fiduciary duties, participate in
    discussions regarding any Parent Superior Proposal in order to be informed
    with respect thereto in order to make any determination permitted pursuant
    to Section 6.3(b)(i). In such event, Parent shall, (i) no less than twenty
    four (24) hours prior to participating in any such discussions, inform the
    Company of the material terms and conditions of such Parent Superior
    Proposal, including the identity of the Person making such Parent Superior
    Proposal and (ii) promptly keep the Company informed of the status including
    any material change to the terms of any such Parent Superior Proposal. As
    used herein, the term "Parent Acquisition Proposal" shall mean any bona fide
    inquiry, proposal or offer relating to any

                                      A-34
<PAGE>
    (i) merger, consolidation, business combination, or similar transaction
    involving Parent or any subsidiary of Parent, (ii) sale, lease or other
    disposition, directly or indirectly, by merger, consolidation, share
    exchange or otherwise, of any assets of Parent or any subsidiary of Parent
    in one or more transactions, (iii) issuance, sale, or other disposition of
    (including by way of merger, consolidation, share exchange or any similar
    transaction) securities (or options, rights or warrants to purchase such
    securities, or securities convertible into such securities) of Parent or any
    subsidiary of Parent, (iv) liquidation, dissolution, recapitalization or
    other similar type of transaction with respect to Parent or any subsidiary
    of Parent, (v) tender offer or exchange offer for Parent securities; in the
    case of (i), (ii), (iii), (iv) or (v) above, which transaction would result
    in a third party (or its shareholders) acquiring more than thirty-five
    percent (35%) of the voting power of Parent or the assets representing more
    than thirty-five percent (35%) of the net income, net revenue or assets of
    Parent on a consolidated basis, (vi) transaction which is similar in form,
    substance or purpose to any of the foregoing transactions or (vii) public
    announcement of an agreement, proposal, plan or intention to do any of the
    foregoing, PROVIDED, HOWEVER, that the term "Parent Acquisition Proposal"
    shall not include the Merger and the transactions contemplated thereby. For
    purposes of this Agreement, "Parent Superior Proposal" means any offer not
    solicited by Parent, or by other persons in violation of the first sentence
    of this Section 6.3(a), and made by a third party to consummate a tender
    offer, exchange offer, merger, consolidation or similar transaction which
    would result in such third party (or its shareholders) owning, directly or
    indirectly, more than fifty percent (50%) of Parent Shares then outstanding
    (or of the surviving entity in a merger) or all or substantially all of the
    assets of Parent and its subsidiaries, taken together, and otherwise on
    terms which the Board of Directors of Parent determines in good faith (based
    on its consultation with a financial advisor of nationally recognized
    reputation and other such matters that it deems relevant) would, if
    consummated, result in a transaction more favorable to Parent's stockholders
    from a financial point of view than the Merger and, in the reasonable good
    faith judgment of the Board of Directors of Parent after consultation with
    its financial advisor the persons or entity making such Parent Superior
    Proposal has the financial means to conclude such transaction. Parent will
    immediately cease any and all existing activities, discussions or
    negotiations with any parties conducted heretofore with respect to any of
    the foregoing.

        (b) Neither the Board of Directors of Parent nor any committee thereof
    shall (i) except as required by their fiduciary duties as determined in good
    faith in consultation with outside counsel, withdraw or modify, or propose
    to withdraw or modify, in a manner adverse to the Company, the approval or
    recommendation by the Board of Directors of Parent or such committee of the
    amendment to Parent's Certificate of Incorporation and the approval of the
    issuance of Parent Shares, (ii) approve, recommend, or otherwise support or
    endorse any Parent Acquisition Proposal, or (iii) cause Parent to enter into
    any letter of intent, agreement in principle, acquisition agreement or
    similar agreement (each a "Parent Acquisition Agreement") with respect to
    any Parent Acquisition Proposal. Nothing contained in this Section 6.3 shall
    prohibit Parent from taking and disclosing to its stockholders a position
    contemplated by Rule 14d-9 or 14e-2 promulgated under the Exchange Act or
    from making any disclosure to Parent's stockholders if, in the good faith
    judgment of the Board of Directors of Parent, in consultation with outside
    counsel, such disclosure is necessary for the Board of Directors to comply
    with its fiduciary duties under applicable law; PROVIDED, HOWEVER, that,
    subject to Section 6.3(b)(i), neither Parent nor its Board of Directors nor
    any committee thereof shall withdraw or modify, or propose publicly to
    withdraw or modify, its position with respect to this Agreement or the
    Merger or approve or recommend or propose publicly to approve or recommend,
    a Parent Acquisition Proposal.

        (c) In addition to the obligations of Parent set forth in paragraphs
    (a) and (b) of this Section 6.3, Parent will promptly (and in any event
    within twenty-four (24) hours) advise the Company, orally and in writing, if
    any Parent Acquisition Proposal is made or proposed to be made or any
    information or access to properties, books or records of Parent is requested
    in connection with a Parent Acquisition Proposal, the principal terms and
    conditions of any such Parent Acquisition Proposal or potential

                                      A-35
<PAGE>
    Parent Acquisition Proposal or inquiry (and will disclose any written
    materials received by Parent in connection with such Parent Acquisition
    Proposal, potential Parent Acquisition Proposal or inquiry) and the identity
    of the party making such Parent Acquisition Proposal, potential Parent
    Acquisition Proposal or inquiry. Parent will keep the Company advised of the
    status and details (including amendments and proposed amendments) of any
    such request or Parent Acquisition Proposal.

    6.4  MEETING OF STOCKHOLDERS.  Parent, on the one hand, and the Company on
the other, shall each take all action necessary in accordance with applicable
law and its Certificate of Incorporation and By-Laws to convene a meeting of its
stockholders (the "Stockholder Meetings") as promptly as practicable to consider
and vote upon the approval of the Merger and the issuance of the Parent Shares,
as the case may be. Subject to the fiduciary duties of each Party's Board of
Directors under applicable law in consultation with independent legal counsel
(who may be the Party's regularly engaged independent legal counsel), the Board
of Directors of Parent, on the one hand, and the Company, on the other, shall
recommend and each shall declare advisable such approval (the requisite approval
by stockholders of the Company as well as by stockholders of Parent is
hereinafter referred to collectively as the "Requisite Stockholder Approval");
provided, however, that the Board of Directors of Parent and the Board of
Directors of the Company shall submit this Agreement to the stockholders of
Parent and the Company, as the case may be, whether or not the Board of
Directors of Parent or the Board of Directors of the Company, as the case may
be, at any time subsequent to the date hereof determines that this Agreement is
no longer advisable or recommends that the stockholders of Parent or the
Company, as the case may be, reject it. Unless the Board of Directors of Parent
or the Board of Directors of the Company, as the case may be, has withdrawn its
recommendation of this Agreement in compliance herewith, each of Parent and the
Company shall use reasonable efforts to solicit from its stockholders proxies in
favor of the approval and adoption of this Agreement and the Merger and to
secure the vote or consent of stockholders required by the DGCL and its
respective Certificate of Incorporation and Bylaws to approve and adopt this
Agreement and the Merger and the issuance of Parent Shares, as the case may be.

    6.5  REGISTRATION STATEMENT.  Parent will, as promptly as practicable,
prepare and file with the SEC a registration statement on Form S-4 (the "S-4
Registration Statement"), containing a proxy statement/ prospectus and a form of
proxy, in connection with the registration under the Securities Act of the
Parent Shares issuable upon conversion of the Shares and the other transactions
contemplated hereby. The Company and Parent will, as promptly as practicable,
prepare and file with the SEC a proxy statement that will be the same proxy
statement/prospectus contained in the S-4 Registration Statement and a form of
proxy, in connection with the vote of the Company's and Parent's stockholders
with respect to the Merger and the issuance of the Parent Shares (such proxy
statement/prospectus, together with any amendments thereof or supplements
thereto, in each case in the form or forms mailed to the Company's and Parent's
stockholders, is herein called the "Joint Proxy Statement"). The Company and
Parent will, and will cause their accountants and lawyers to, use their
reasonable efforts to have or cause the S-4 Registration Statement declared
effective as promptly as practicable, including, without limitation, causing
their accountants to deliver necessary or required instruments such as opinions,
consents and certificates, and will take any other action required or necessary
to be taken under federal or state securities laws or otherwise in connection
with the registration process, it being understood and agreed that Katten
Muchin & Zavis, counsel to Parent, and Wilson Sonsini Goodrich & Rosati, P.C.,
counsel to the Company, will each render the tax opinions referred to in Section
7.1(g) and 7.1(h), respectively, on (i) the date the preliminary Joint Proxy
Statement is filed with the SEC and (ii) the date the S-4 Registration Statement
is filed with the SEC. The Company and Parent will each use their reasonable
efforts to cause the Joint Proxy Statement to be mailed to their respective
stockholders at the earliest practicable date and will coordinate and cooperate
with one another with respect to the timing of the Stockholder Meetings and the
Company and Parent shall each use their commercially reasonable efforts to hold
such Stockholder Meetings as soon as practicable after the date hereof. Parent
shall also take any action required to be taken under state blue sky or other
securities laws in connection with the issuance of Parent Shares in the Merger.

    6.6  REASONABLE EFFORTS.  The Parties shall: (i) promptly make their
respective filings and thereafter make any other required submissions under all
applicable laws with respect to the Merger and the other transactions
contemplated hereby; and (ii) use their reasonable efforts to promptly take, or
cause to be taken, all other actions and do, or cause to be done, all other
things necessary, proper or appropriate to consummate and make effective the
transactions contemplated by this Agreement as soon as practicable.

    6.7  ACCESS TO INFORMATION.  Upon reasonable notice, Parent, on the one
hand, and the Company, on the other, shall (and shall cause each of their
subsidiaries to) afford to officers, employees, counsel, accountants and other
authorized representatives of the other such party (the "Authorized
Representatives") reasonable access, during normal business hours throughout the
period prior to the Effective Time, to their properties, assets, books and
records and, during such period, shall (and shall cause each of their
subsidiaries to) furnish promptly to such Authorized Representatives all
information concerning their business, properties, assets and personnel as may
reasonably be requested for purposes of appropriate and necessary due diligence,
provided that no investigation pursuant to this Section 6.7 shall affect or be
deemed to modify any of the representations or warranties made by the Parties.
The Parties each agree to treat (and cause their Authorized Representatives to
treat) any and all information provided pursuant to this Section 6.7 in strict
compliance with the terms of that certain Confidentiality Agreement, entered by
and between the Company and Parent, dated November 18, 1999 (the
"Confidentiality Agreement").

    6.8  PUBLICITY.  The Parties agree that they will consult with each other
concerning any proposed press release or public announcement pertaining to the
Merger in order to agree upon the text of any such press release or the making
of such public announcement, which agreement shall not be unreasonably withheld,
except as may be required by applicable law or by obligations pursuant to any
listing agreement with an national securities exchange or national automated
quotation system, in which case the party proposing to issue such press release
or make such public announcement shall use reasonable efforts to consult in good
faith with the other party before issuing any such press release or making any
such public announcement. Notwithstanding the foregoing, in the event the Board
of Directors of Parent or the Company withdraws its recommendation of this
Agreement in compliance herewith, neither party will be required to consult with
or obtain the agreement of the other in connection with any press release or
public announcement.

    6.9  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        (a) From and after the Effective Time, Parent shall, and in addition
    shall cause the Surviving Corporation to, indemnify, defend and hold
    harmless the present and former officers and directors of the Company and
    any of their subsidiaries against all losses, expenses, claims, damages or
    liabilities arising out of actions or omissions occurring on or prior to the
    Effective Time (including, without limitation, the transactions contemplated
    by this Agreement) to the full extent (not otherwise covered by insurance)
    permitted or required under applicable law (and shall also advance expenses
    as incurred to the fullest extent permitted under applicable law, PROVIDED
    that the Person to whom expenses are advanced provides an undertaking to
    repay such advances if it is ultimately determined that such Person is not
    entitled to indemnification); PROVIDED, HOWEVER, the indemnification
    provided hereunder by Parent shall not be greater than the greater of (x)
    the indemnification actually provided pursuant to the Company's Certificate
    of Incorporation and By-Laws, as in effect as of the date hereof or (y) the
    indemnification actually provided by the Company as of the date hereof.
    Parent agrees that all rights to indemnification, including provisions
    relating to advances of expenses incurred in defense of any action or suit,
    existing in favor of the present or former directors, officers, employees,
    fiduciaries and agents of the Company, Parent or any of their subsidiaries
    (collectively, the "Indemnified Parties") as provided in, as the case may
    be, the Company's Certificate of Incorporation or By-Laws or pursuant to
    other agreements, or articles or certificates of incorporation or by-laws or
    similar documents of any of the Company's or Parent's subsidiaries, as in
    effect as of the date hereof, with respect to matters occurring through the
    Effective Time, shall survive the Merger.

                                      A-37
<PAGE>
        (b) Parent shall cause to be maintained in effect for not less than six
    (6) years the current policies of directors' and officers' liability
    insurance and fiduciary liability insurance maintained by the Company,
    Parent and their subsidiaries with respect to matters occurring prior to the
    Effective Time to the extent required to cover the types of actions and
    omissions currently covered by such policies; PROVIDED, HOWEVER, that
    (i) Parent may substitute therefor policies of substantially the same
    coverage containing terms and conditions which are not less advantageous, in
    any material respect, to the Indemnified Parties and (ii) Parent shall not
    be required to pay an annual premium for such insurance in excess of two
    hundred percent (200%) of current aggregate policies but in such case shall
    purchase as much coverage as possible for such amount.

        (c) In the event that any action, suit, proceeding or investigation
    relating hereto or to the transactions contemplated by this Agreement is
    commenced, whether before or after the Closing, the parties hereto agree to
    cooperate and use their respective commercially reasonable efforts to
    vigorously defend against and respond thereto.

        (d) This Section 6.9 is intended to benefit the Indemnified Parties and
    shall be binding on all successors and assigns of the Parties.

    6.10  AFFILIATES OF THE COMPANY AND PARENT.  The Company has identified to
Parent each "affiliate" of the Company for purposes of Rule 145 promulgated
under the Securities Act (each, a "Company Affiliate") and the Company will use
its reasonable efforts to obtain as promptly as practicable from each Company
Affiliate written agreements in the form attached hereto as EXHIBIT C (the
"Company Affiliate Letter") that such Company Affiliate will not sell, pledge,
transfer or otherwise dispose of any Parent Shares issued to such Company
Affiliate pursuant to the Merger, except in compliance with Rule 145 promulgated
under the Securities Act or an exemption from the registration requirements of
the Securities Act.

    6.11  MAINTENANCE OF INSURANCE.  Between the date hereof and through the
Effective Time each of the Company and Parent will maintain in full force and
effect all of their and their subsidiaries presently existing policies of
insurance or insurance comparable to the coverage afforded by such policies.

    6.12  REPRESENTATIONS AND WARRANTIES.  Each of the Company and Parent shall
give prompt notice to the other of any circumstances that would cause any of
their respective representations and warranties set forth in Section 5.1 or 5.2,
as the case may be, not to be true and correct in all material respects at and
as of the Effective Time.

    6.13  FILINGS; OTHER ACTION.  Subject to the terms and conditions herein
provided, the Parties shall: (a) promptly make their respective filings and
thereafter make any other required submissions under the HSR Act, the Securities

do, or cause to be done, all other things necessary, proper or appropriate under
applicable laws and regulations to consummate and make effective the
transactions contemplated by this Agreement as soon as practicable.

    6.14  TAX-FREE REORGANIZATION TREATMENT.  Prior to the Effective Time, the
Parties shall use their best efforts to cause the Merger to be treated as a
reorganization within the meaning of Section 368 of the Code and to obtain the
opinion of their respective counsels contemplated by Section 7.1 and shall not
knowingly take or fail to take any action which action or failure to act would
jeopardize the qualification of the Merger as a reorganization within Section
368 of the Code.

    6.15  COMPANY OPTIONS; COMPANY ESPPS.

        (a) After the Effective Time, except as provided above, each Substitute
    Option shall be subject to the same terms and conditions as were applicable
    under the related Company Option immediately prior to the Effective Time.
    The Company agrees that it will not grant any stock appreciation rights or
    limited stock appreciation rights and will not permit cash payments to
    holders of Company Options in lieu of the substitution therefor of
    Substitute Options, as described herein. As soon as practicable after the
    Effective Time, Parent shall deliver to each holder of a Company Option an
    appropriate notice setting forth such holder's right to acquire Parent
    Shares and Company Option agreements of such holder shall be deemed to be
    appropriately amended so that such Company Options shall represent rights to
    acquire Parent Shares on substantially the same terms and conditions as
    contained in the outstanding Company Options.

        (b) From and after the date hereof, the Company (i) shall not commence
    any "offering periods" or "purchase periods" under its 1997 Employee Stock
    Purchase Plan or the CKS Group, Inc. Employee Stock Purchase Plan
    (collectively, the "Company ESPPs") and shall apply all amounts deducted and
    withheld thereunder to purchase shares of the Company in accordance with the
    provisions thereof, (ii) shall not grant any bonuses under its Acquisition
    Stock Bonus Plan, and (iii) shall terminate the Company ESPPs or the
    Acquisition Stock Purchase Plan and the Acquisition Stock Purchase Plan as
    of the Effective Time. Parent shall have no obligation or duty in respect of
    the Company ESPPs or the Acquisition Stock Purchase Plan or the rights
    granted thereunder.

        (c) Parent shall file and use commercially reasonable efforts to cause
    there to be effective within one week of the Effective Time a registration
    statement on Form S-8 (or any successor form) or other appropriate forms,
    with respect to Parent Shares subject to such Company Options and shall use
    commercially reasonable efforts to maintain the effectiveness of such
    registration statement or registration statements (and maintain the current
    status of the prospectus or prospectuses contained therein) for so long as
    such Company Options remain outstanding.

    6.16  STOCKHOLDERS AGREEMENTS.  Concurrently with the execution and delivery
of this Agreement, each of the Voting Stockholders has executed and delivered
each Stockholders Agreement, as applicable.

    6.17  BOARD COMPOSITION.  The Board of Directors of Parent will take all
actions within its power to cause the Board of Directors of Parent, effective
upon the Effective Time, to consist of nine (9) Persons, four (4) of whom shall
have served on the Board of Directors of Parent ("Parent Directors") immediately
prior to the Effective Time (including the Chief Executive Officer of Parent as
of the date of this Agreement), and four (4) of whom shall have served on the
Board of Directors of the Company ("Company Directors") immediately prior to the
Effective Time (including the Chief Executive Officer of the Company as of the
date of this Agreement), and the "New Director." The "New Director" shall be a
person who is not a current director or employee of Parent or the Company, and
shall be selected by the Chief Executive Officer of Parent, with the consent of
the Chief Executive Officer of the Company, which consent cannot be unreasonably
withheld or delayed. The first class of directors, with a term expiring at
Parent's 2000 annual meeting of stockholders, (and such persons shall be
nominated for election at such meeting for a term expiring at Parent's 2003
annual meeting) shall include one (1) Parent Director and one (1) Company
Director. The second class of directors, with a term expiring at Parent's 2001

(2) Company Directors, one of whom shall be Robert Shaw. The third class of
directors, with a term expiring at Parent's 2002 annual meeting of stockholders,
shall include one (1) Parent Director, one (1) Company Director and the New
Director. If, prior to the Effective Time, any of the Parent or the Company
designees shall decline or be unable to serve as a director of Parent, the
Company (if such Person was designated by the Company) or Parent (if such Person
was designated by Parent) shall designate another Person to serve in such
Person's stead, which Person shall be reasonably acceptable to the other party.

whole). At the Effective Time, the Chief Operating Officer Robert Clarkson, the
Chief Creative Officer Thomas Suiter, the Chief Strategist & Information Officer
Ian Small, and the Chief People Officer Richard Evans, of the Company, as of the
date of this Agreement will be offered positions as the Chief Operating Officer,

of Incorporation be amended at the Effective Time to change its name to a new
name to be agreed upon by Parent and the Company.

    6.20  CONTEMPLATED TERMINATION OF 401(K) PLAN(S).  Parent and its Plan
Affiliates and Company and its Plan Affiliates each agree to evaluate whether
the termination of any of their 401(k) plans is reasonable in light of the
Merger contemplated herein. To the extent that Parent and Company agree to
terminate one (1) or more 401(k) plans prior to the Effective Time, the sponsor
of such plan will take any and all actions required under the circumstances to
effectuate such termination prior to the Effective Time including, without
limitation, resolutions of that entity's Board of Directors (the form and
substance of which resolutions shall be subject to review and approval by the
other entity).

    6.21  CREDITING SERVICE AND PROVIDING OTHER BENEFITS.  Parent shall either
(i) adopt and maintain any or all employee welfare benefit plan, as defined in
Section 3(1) of ERISA and as specified in Section 5.2(m) of the Company
Disclosure Schedule (the "Scheduled Welfare Plans"), and, accordingly, shall
thereby continue in full force and effect each Scheduled Welfare Plan subject to
the terms and conditions thereof, to the extent such Scheduled Welfare Plan is
offered as of the Effective Time to each eligible employee of the Company and
its participating Affiliates, his or her dependents and each Qualified
Beneficiary (as such term is defined in COBRA); or (ii) provide all eligible
employees of the Company and their dependents and all Qualified Beneficiaries
(as such term is defined in COBRA) with coverage under one or more of Parent's
employee welfare benefit plans (as defined in Section 3(1) of ERISA) that
corresponds to a Scheduled Welfare Plan which meets all of the following
requirements as of the Effective Time (the "Successor Welfare Plan"): (A) the
coverage is as favorable as that provided to Parent employees in similar
circumstances, (B) service with the Company or its Affiliates prior to the
Effective Time shall be credited against all service and waiting period
requirements under the Successor Welfare Plan(s), (C) Parent shall make its
commercially reasonable best efforts to have the Successor Welfare Plan(s) not
provide any pre-existing condition exclusion(s) to persons who were not excluded
under the Company Scheduled Plans, and (D) the deductibles and co-payments in
effect under the Successor Welfare Plan(s) shall be reduced by any deductibles
and/or co-payments, respectively, paid by such individuals under the
corresponding Scheduled Welfare Plan for the plan year in which the Effective
Time occurs. In addition, service with the Company shall be recognized for all
purposes under Parent's compensation and benefit plans, programs, policies and
arrangements, except where crediting such service would result in a duplication
of benefits or is not legally permissible. Without limiting the generality of
the foregoing, Parent shall honor all vacation, personal and sick days accrued
by Continuing Employees under the Company's plans, policies, programs and
arrangements immediately prior to the Effective Time to the same extent required
to be honored under the Company's plan, programs, policies and arrangements in
effect on the date hereof.

    6.22  EARN-OUT SHARES.  The Company shall use its reasonable efforts to
amend all acquisition agreements to which it or one of its subsidiaries is a
party and that provide for the future issuance of Company Shares or shares of
capital stock of a subsidiary ("Subsidiary Shares") as deferred consideration,
purchase price adjustment or otherwise, to allow for the issuance of Parent
Shares in lieu of Company Shares or Subsidiary Shares in an amount equal to, (i)
with respect to the Company Shares, the number of Company Shares otherwise
issuable, multiplied by the Exchange Ratio, and (ii) with respect to the

                                      A-40
<PAGE>
Subsidiary Shares, the number of Subsidiary Shares otherwise issuable,
multiplied by a factor that appropriately reflects the exchange ratio or other
valuation factor used in the acquisition of the respective subsidiary by the
Company.

    6.23  EXEMPTION FROM LIABILITY UNDER SECTION 16(B).

        (a) Provided that the Company delivers to Parent the Section 16
    Information with respect to the Company prior to the Effective Time, the
    Board of Directors of Parent, or a committee of Non-Employee Directors
    thereof (as such term is defined for purposes of Rule 16b-3(d) under the
    Exchange Act), shall adopt a resolution in advance of the Effective Time
    providing that the receipt by the Company Insiders of Parent Shares in
    exchange for Company Shares, and of options to purchase Parent Shares in
    exchange for shares of Company Shares, and of options to purchase Parent
    Shares upon assumption and conversion by Parent of options to purchase
    Company Shares, in each case pursuant to the transactions contemplated
    hereby and to the extent such securities are listed in the Section 16
    Information, are intended to be exempt from liability pursuant to
    Rule 16b-3 under the Exchange Act.

        (b) "Section 16 Information" shall mean information accurate in all
    respects regarding the Company Insiders, the number of Company Shares or
    other Company equity securities deemed to be beneficially owned by each
    Company Insider and expected to be exchanged for Parent Shares in connection
    with the Merger.

        (c) "Company Insiders" shall mean those officers and directors of
    Company who are subject to the reporting requirements of Section 16(a) of
    the Exchange Act who are listed in Section 16 Information.

    there shall not be pending any suit, action or proceeding by any
    Governmental Entity preventing the consummation of the Merger; PROVIDED,

    prevent the entry of such Restraints and to appeal as promptly as possible
    any such Restraints that may be entered;

    satisfactory to them, to the effect that the Merger will constitute a
    tax-free reorganization within the meaning of Section 368(a) of the Code and
    such opinions shall not have been withdrawn; PROVIDED, HOWEVER, that if the

        (d) from the date of this Agreement to the Effective Time, there shall
    not have been any event or development which has resulted in a Material
    Adverse Effect (other then any Material Adverse Effect Exception) on Parent
    nor shall there have occurred any event or development which could
    reasonably be likely to result in the future in a Material Adverse Effect on
    Parent (other than any Material Adverse Effect Exception);

    warrants or other commitments, and (y) the number of Company Shares
    outstanding or the number of Company Shares issuable under outstanding
    options, warrants or other commitments set forth in Section 5.2(b) is equal
    to or greater than one-half percent (0.5%) of the number set forth in
    Section 5.2(b)), and those that are no so qualified shall be true and
    correct in all material respects, in each case as of the date of this
    Agreement, and as of the Effective Time with the same force and effect as if

of either the Company or Parent if:

        (a) the Merger shall not have been consummated by May 31, 2000 (the

    Agreement under this Section 8.2(a) shall not be available to any party
    whose failure to fulfill any obligation under this Agreement has been the
    principal cause of or resulted in the failure of the Merger to occur on or
    before such date and such action or failure to act constitutes a material
    breach of this Agreement;

    Article VIII, this Agreement shall forthwith become void and there shall be
    no liability or obligation on the part of the Parties or their respective
    affiliates, officers, directors or stockholders except (x) with respect to
    the treatment of confidential information pursuant to Section 6.6, the
    payment of expenses pursuant to Section 9.1, and Article IX generally, (y)
    to the extent that such termination results from the willful breach of a

    or agreements or (z) intentional or knowing misrepresentation in connection
    with this Agreement or the transactions contemplated hereby.

        (b) In the event that (i) a Company Acquisition Proposal or the
    intention to make a Company Acquisition Proposal shall have been made
    directly to the stockholders of the Company generally or otherwise publicly
    announced by the Company or the Person making such Company Acquisition
    Proposal, AND such Company Acquisition Proposal or intention is not
    irrevocably and publicly withdrawn prior to the vote of the Company
    stockholders at the Company's duly held Stockholders' Meeting, AND
    thereafter this Agreement is terminated by either the Company or Parent
    pursuant to Section 8.2(a) [Drop dead date] due to the Company's
    Stockholders' Meeting not occurring as a result of such Company Acquisition
    Proposal or (c)(i) [Company stockholder disapproval], or (ii) this Agreement
    is terminated by Parent pursuant to Section 8.4(b) [Company Board withdraws
    recommendation], then the Company shall promptly, but in no event later than
    the date of such termination, pay Parent a fee equal to $150 million (the
    "Termination Fee"), payable by wire transfer of same day funds; PROVIDED,
    HOWEVER, that no Termination Fee shall be payable to Parent pursuant to

    Company Acquisition Agreement with respect to, or consummates, any Company
    Acquisition Proposal (for the purposes of the foregoing proviso the term
    "Company Acquisition Proposal" shall have the meaning assigned to such term
    in Section 6.2 except that references to 35% in the definition of "Company
    Acquisition Proposal" in Section 6.2 as they relate to net revenues, net
    income, voting power or assets of Company shall be deemed to be references

    subsequent to such termination contemplated by clause (i) of this paragraph
    (b) with the same person or an affiliate of the person that made and
    withdrew a Company Acquisition Proposal prior to such termination, the
    Company shall pay Parent the Termination Fee at the time contemplated by the
    preceding proviso. The Company acknowledges that the agreements contained in
    this Section 8.5(b) are an integral part of the transactions contemplated by
    this Agreement, and that, without these agreements, Parent would not enter
    into this Agreement, and accordingly, if the Company fails promptly to pay
    the amount due pursuant to this Section 8.5(b), and, in order to obtain such
    payment, Parent commences a suit which results in a judgment against the
    Company for the fee set forth in this Section 8.5(b), the Company shall pay
    to Parent its costs and expenses (including reasonable attorneys' fees and
    expenses) in connection with such suit, together with interest on the amount

    to make a Parent Acquisition Proposal shall have been made directly to the
    stockholders of Parent generally or otherwise publicly announced by Parent
    or the Person making such Parent Acquisition Proposal, AND such Parent
    Acquisition Proposal or intention is not irrevocably and publicly withdrawn
    prior to the vote of Parent stockholders at the duly held Stockholders'
    Meeting, AND thereafter this Agreement is

                                      A-45
<PAGE>
    terminated by either Parent or the Company pursuant to Section 8.2(a) due to
    the Parent's Stockholders' Meeting not occurring as a result of such Parent
    Acquisition Proposal or (c)(ii) [Parent stockholder disapproval], or
    (ii) this Agreement is terminated by the Company pursuant to Section
    8.3(b) [Parent Directors withdraw recommendation], then Parent shall
    promptly, but in no event later than the date of such termination, pay the
    Company the Termination Fee, payable by wire transfer of same day funds;
    PROVIDED, HOWEVER, that no Termination Fee shall be payable to the Company
    pursuant to clause (i) of this paragraph (c) unless and until within twelve
    (12) months of such termination Parent or any of its subsidiaries enters
    into any Parent Acquisition Agreement with respect to, or consummates, any
    Parent Acquisition Proposal (for the purposes of the foregoing proviso the
    term "Parent Acquisition Proposal" shall have the meaning assigned to such
    term in Section 6.3 except that references to 35% in the definition of
    "Parent Acquisition Proposal" in Section 6.3 as they relate to net revenues,
    net income, voting power or assets of Parent, shall be deemed to be
    references to "50%"), in which event the Termination Fee shall be payable
    upon the first to occur of such events; PROVIDED FURTHER, that if the Parent
    consummates a Parent Acquisition Proposal during the twelve (12) month
    period subsequent to such termination contemplated by clause (i) of this
    paragraph (c) with the same person or an affiliate of such person that made
    and withdrew a Parent Acquisition Proposal prior to such termination, Parent
    shall pay the Company the Termination Fee at the time contemplated by the
    preceding proviso. Parent acknowledges that the agreements contained in this
    Section 8.5(c) are an integral part of the transactions contemplated by this
    Agreement, and that, without these agreements, the Company would not enter
    into this Agreement; accordingly, if Parent fails promptly to pay the amount
    due pursuant to this Section 8.5(c), and, in order to obtain such payment,
    the Company commences a suit which results in a judgment against Parent for
    the fee set forth in this Section 8.5(c), Parent shall pay to the Company
    its costs and expenses (including reasonable attorneys' fees and expenses)
    in connection with such suit, together with interest on the amount of the
    fee at the prime rate of Citibank, N.A. in effect on the date such payment
    was required to be made.

        (d) If this Agreement is terminated under circumstances in which a party
    is entitled to receive the Termination Fee, the payment of such Termination
    Fee shall be the sole and exclusive remedy available to such party, except
    in the event of (x) a willful breach by the other party of any provision of
    this Agreement in any material respect, or (y) the intentional or knowing
    misrepresentation in connection with this Agreement or the transactions
    contemplated hereby, in which event the non-breaching Party shall have all
    rights, powers and remedies against the breaching Party which may be
    available at law or in equity. All rights, powers and remedies provided
    under this Agreement or otherwise available in respect hereof at law or in
    equity shall be cumulative and not alternative, and the exercise of any such
    right, power or remedy by any Party shall not preclude the simultaneous or
    later exercise of any other such right, power or remedy by such Party.

                                   ARTICLE IX
                           MISCELLANEOUS AND GENERAL

    9.1  PAYMENT OF EXPENSES.  Whether or not the Merger shall be consummated,

and carrying out this Agreement and the consummation of the transactions
contemplated hereby, provided that the Surviving Corporation shall pay any and
all property or transfer taxes imposed on the Surviving Corporation. The filing
fee and the cost of printing the S-4 Registration Statement and the Joint Proxy
Statement and the filing fee for the required filing under the HSR Act shall be
borne equally by the Company and Parent.

    9.2  NON-SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  The representations
and warranties made herein shall not survive beyond the Effective Time or a
termination of this Agreement, except to the extent a willful breach of such
representation or intentional or knowing misrepresentation formed the basis for
such termination. This Section 9.2 shall not limit any covenant or agreement of
the Parties which by its terms contemplates performance after the Effective
Time.

Board of Directors
USWeb Corporation
410 Townsend Street
San Francisco, California 94107

Members of the Board:

We understand that USWeb Corporation ("USWeb"), Whittman-Hart, Inc.
("Whittman-Hart"), and Merger Sub ("Merger Sub"), a wholly-owned subsidiary of
Whittman-Hart, propose to enter into an Agreement and Plan of Merger,
substantially in the form of the draft dated December 12, 1999 (the "Merger
Agreement") which provides, among other things, for the merger (the "Merger") of
Merger Sub with and into USWeb. Pursuant to the Merger, USWeb will become a
wholly-owned subsidiary of Whittman-Hart and each outstanding share of common
stock, par value $0.001 per share (the "USWeb Common Stock"), of USWeb, other
than shares held in treasury or held by Whittman-Hart or any affiliate of
Whittman-Hart or USWeb or as to which dissenters' rights have been perfected,
will be converted into the right to receive 0.865 shares (the "Exchange Ratio")
of common stock, par value $0.001 per share, of Whittman-Hart (the
"Whittman-Hart Common Stock"). The terms and conditions of the Merger are more
fully set forth in the Merger Agreement.

You have asked for our opinion as to whether the Exchange Ratio pursuant to the
Merger Agreement is fair from a financial point of view to the holders of common
stock of USWeb.

For purposes of the opinion set forth herein, we have:

    (i) reviewed certain publicly available financial statements and other
        information of Whittman-Hart and USWeb;

    (ii) reviewed certain internal financial statements and other financial and
         operating data concerning Whittman-Hart and USWeb prepared by the
         managements of Whittman-Hart and USWeb, respectively;

   (iii) discussed the past and current operations and financial condition and
         the prospects of Whittman-Hart, including information relating to
         certain strategic, financial and operational benefits anticipated from
         the Merger, with senior executives of Whittman-Hart;

    (iv) discussed the past and current operations and financial condition and
         the prospects of USWeb, including information relating to certain
         strategic, financial and operational benefits anticipated from the
         Merger, with senior executives of USWeb;

    (v) reviewed the pro forma impact of the Merger on the earnings per share of
        Whittman-Hart;

    (vi) reviewed the reported prices and trading activity for the Whittman-Hart
         Common Stock and USWeb Common Stock;

   (vii) compared the financial performance of Whittman-Hart and USWeb and the
         prices and trading activity of the Whittman-Hart Common Stock and USWeb
         Common Stock with that of certain other publicly-traded companies and
         their securities;


  (viii) analyzed the contribution of revenues and earnings from USWeb and
         Whittman-Hart to the combined company;


    (ix) reviewed and discussed with the senior managements of Whittman-Hart and
         USWeb their strategic rationales for the Merger;

    (x) participated in discussions and negotiations among representatives of
        Whittman-Hart and USWeb and their financial and legal advisors;

    (xi) reviewed the draft Merger Agreement and certain related agreements; and

   (xii) performed such other analyses and considered such other factors as we
         have deemed appropriate.

We have assumed and relied upon, without independent verification, the accuracy
and completeness of the information reviewed by us for the purposes of this
opinion. With respect to the internal financial statements and other financial
and operating data, and discussions relating to the strategic, financial and
operational benefits anticipated from the Merger provided by Whittman-Hart and
USWeb, we have assumed that they have, in each case, been reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
prospects of Whittman-Hart and USWeb. We have relied upon the assessment by the
managements of Whittman-Hart and USWeb of their ability to retain key employees
of Whittman-Hart and USWeb. We have also relied upon, without independent
verification, the assessment by the managements of Whittman-Hart and USWeb of:
(i) the strategic and other benefits expected to result from the Merger;
(ii) the timing and risks associated with the integration of Whittman-Hart and
USWeb; and (iii) the validity of, and risks associated with, Whittman-Hart's and
USWeb's existing and future technologies, services or business models. We have
not made any independent valuation or appraisal of the assets or liabilities or
technology of Whittman-Hart and USWeb, nor have we been furnished with any such
appraisals. In addition, we have assumed that the Merger will be consummated in
accordance with the terms set forth in the Merger Agreement including that the
Merger shall qualify as a reorganization within the meaning of Section 368 of
the Internal Revenue Code of 1986 (as amended). Our opinion is necessarily based
on financial, economic, market and other conditions as in effect on, and the
information made available to us as of, the date hereof.

We have acted as financial advisor to the Board of Directors of USWeb in
connection with this transaction and will receive a fee for our services. In the
ordinary course of our business we may actively trade the securities of USWeb
and Whittman-Hart for our own account and for the accounts of our customers and,
accordingly, may at any time hold a long or short position in such securities.

It is understood that this letter is for the information of the Board of
Directors of USWeb, except that this opinion may be included in its entirety in
any filing made by USWeb with the Securities and Exchange Commission in respect
of the transaction. In addition, this opinion does not in any manner address the
prices at which the USWeb Common Stock and the Whittman-Hart Common Stock will
actually trade at any time and we express no recommendation or opinion as to how
the holders of USWeb Common Stock should vote at the stockholders' meeting held
in connection with the Merger.

Based upon and subject to the foregoing, we are of the opinion on the date
hereof that the Exchange Ratio pursuant to the Merger Agreement is fair from a
financial point of view to the holders of common stock of USWeb.

                                          Very truly yours,

Board of Directors
Whittman-Hart, Inc.
311 S. Wacker Drive
Suite 3500
Chicago, Illinois 60606-6618

Members of the Board:

You have asked us to advise you with respect to the fairness to
Whittman-Hart, Inc. ("Whittman-Hart") from a financial point of view of the
Exchange Ratio (as defined below) set forth in the Agreement and Plan of Merger,
dated as of December 12, 1999 (the "Merger Agreement"), by and among Whittman-
Hart, Whittman-Hart Sub, Inc., a wholly owned subsidiary of Whittman-Hart
("Merger Sub"), and USWeb Corporation ("USWeb"). The Merger Agreement provides
for, among other things, the merger (the "Merger") of Merger Sub with and into
USWeb pursuant to which each outstanding share of the common stock, par value
$0.001 per share, of USWeb will be converted into the right to receive 0.865
(the "Exchange Ratio") of a share of the common stock, par value $0.001 per
share ("Whittman-Hart Common Stock"), of Whittman-Hart.

In arriving at our opinion, we have reviewed the Merger Agreement and certain
publicly available business and financial information relating to Whittman-Hart
and USWeb. We have also reviewed certain other information relating to
Whittman-Hart and USWeb, including financial forecasts, provided to or discussed
with us by Whittman-Hart and USWeb, and have met with the managements of
Whittman-Hart and USWeb to discuss the businesses and prospects of Whittman-Hart
and USWeb, including the ability to integrate the businesses of Whittman-Hart
and USWeb. We have also considered certain financial and stock market data of
Whittman-Hart and USWeb, and we have compared those data with similar data for
other publicly held companies in businesses similar to those of Whittman-Hart
and USWeb, and we have considered, to the extent publicly available, the
financial terms of certain other business combinations and other transactions
which have recently been effected. We also considered such other information,
financial studies, analyses and investigations and financial, economic and
market criteria which we deemed relevant.


In connection with our review, we have not assumed any responsibility for
independent verification of any of the foregoing information and have relied on
such information being complete and accurate in all material respects. With
respect to the financial information relating to Whittman-Hart and USWeb, we
have been advised, and have assumed, that such information represents reasonable
estimates and judgments as to the future financial performance of Whittman-Hart
and USWeb. You also have informed us, and we have assumed, that the Merger will
be treated as a tax-free reorganization for federal income tax purposes. In
addition, we have not been requested to make, and have not made an independent
evaluation or appraisal of the assets or liabilities (contingent or otherwise)
of Whittman-Hart or USWeb, nor have we been furnished with any such evaluations
or appraisals. Our opinion is necessarily based upon information available to
us, and financial, economic, market and other conditions as they exist and can
be evaluated on the date hereof. We are not expressing any opinion as to the
actual value of the Whittman-Hart Common Stock when issued pursuant to the
Merger or the price at which the Whittman-Hart Common Stock will trade
subsequent to the Merger.

We have acted as financial advisor to Whittman-Hart in connection with the
Merger and will receive a fee for our services, a significant portion of which
is contingent upon the consummation of the Merger. We will also receive a fee
upon delivery of this opinion. Credit Suisse First Boston and its affiliates
have in the past provided financial services to Whittman-Hart and USWeb
unrelated to the Merger, for which we have received compensation. In the
ordinary course of business, Credit Suisse First Boston and its affiliates may
actively trade the equity securities of both Whittman-Hart and USWeb for their
own accounts and for the accounts of customers and, accordingly, may at any time
hold a long or short position in such securities.

It is understood that this letter is for the information of the Board of
Directors of Whittman-Hart in connection with its evaluation of the Merger, does
not constitute a recommendation to any stockholder as to how such stockholder
should vote with respect to any matter relating to the Merger, and is not to be
quoted or referred to, in whole or in part, in any registration statement,
prospectus or proxy statement, or in any other document used in connection with
the offering or sale of securities, nor shall this letter be used for any other
purposes, without our prior written consent, except that this letter may be
attached in its entirety as an exhibit to any registration statement, prospectus
or proxy statement relating to the Merger.

Based upon and subject to the foregoing, it is our opinion that, as of the date
hereof, the Exchange Ratio is fair to Whittman-Hart from a financial point of
view.

Very truly yours,

Notwithstanding the foregoing, nothing in this Section 3 shall require the
Stockholder to exercise any options with respect to Company Shares.

    4.  GRANT OF PROXY; APPOINTMENT OF PROXY.  (a) The Stockholder hereby
irrevocably grants to, and appoints, the Board of Directors of Parent, the
Stockholder's proxy and attorney-in-fact (with full power of substitution), for

modification or acceleration) under any of the terms, conditions or provisions

execution and delivery of this Stockholder Agreement.

    6.  STOP TRANSFER LEGEND.

    (a) The Stockholder agrees and covenants to Parent that the Stockholder

Stockholder Agreement.

    (b) Without limiting the covenants set forth in paragraph (a) above, in the
event of a stock dividend or distribution, or any change in Shares by reason of
any stock dividend, split-up, recapitalization, combination, exchange of shares
or the like, other than pursuant to the Merger, the term "Shares" shall be
deemed to refer to and include the Shares into which or for which any or all of
the Shares may be changed or exchanged and appropriate adjustments shall be made
to the terms and provisions of this Stockholder Agreement.

    7.  FURTHER ASSURANCES.  From time to time, at Parent's request and without
further consideration, the Stockholder shall execute and deliver such additional

                           WHITTMAN-HART CORPORATION
                           1995 INCENTIVE STOCK PLAN



    1.  PURPOSE.  The WHITTMAN-HART CORPORATION 1995 Incentive Stock Plan (the
"Plan") is intended to provide incentives which will attract and retain highly
competent persons as officers and employees of WHITTMAN-HART CORPORATION and its
subsidiaries (the "Company"), by providing them opportunities to acquire shares
of Common Stock of the Company ("Common Shares") or to receive monetary payments
based on the value of such shares pursuant to the Awards described herein.


    2.  ADMINISTRATION.  The Plan will be administered by the Stock Option
Committee (the "Committe") appointed by the Board of Directors of the Company
from among its members PROVIDED, HOWEVER, that as long as Common Shares are
registered under the Securities Exchange Act of 1934, members of the Committee
must qualify as disinterested persons within the meaning of Securities and
Exchange Commission Regulation Section240.16b-3. The Committee is authorized,
subject to the provisions of the Plan, to establish such rules and regulations
as it deems necessary for the proper administration of the Plan and to make such
determinations and interpretations and to take such action in connection with
the Plan and any Awards granted hereunder as it deems necessary or advisable.
All determinations and interpretations made by the Committee shall be binding
and conclusive on all participants and their legal representatives. No member of
the Board, no member of the Committee and no employee of the Company shall be
liable for any act or failure to act hereunder, by any other member or employee
or by any agent to whom duties in connection with the administration of this
Plan have been delegated or, except in circumstances involving his bad faith,
gross negligence or fraud, for any act or failure to act by the member or
employee.

    3.  PARTICIPANTS.  Participants will consist of such officers and employees
of the company, as the Committee in its sole discretion determines to be
significantly responsible for the success and future growth and profitability of
the Company and whom the Committee may designate from time to time to receive
Awards under the Plan. Designation of a participant in any year shall not
require the Committee to designate such person to receive an Award in any other
year or, once designated, to receive the same type or amount of Awards as
granted to the participant in any year. The Committee shall consider such
factors as it deems pertinent in selecting participants and in determining the
type and amount of their respective Awards. The maximum number of Common Shares
which may be awarded to any participant in any year during the term of the Plan
is 100,000 shares.

    4.  TYPES OF AWARDS.  Awards under the Plan may be granted in any one or a
combination of (a) Stock Options, (b) Stock Appreciation Rights, (c) Stock
Awards, (d) Performance Shares, and (e) Performance Units, all as described
below (collectively "Awards").

    5.  SHARES RESERVED UNDER THE PLAN.  There is hereby reserved for issuance
under the Plan an aggregate of twenty four million (24,000,000) Common Shares,
which may be authorized but unissued shares. Any shares subject to any form of
Award hereunder may thereafter be subject to new Awards under this Plan if there
is a lapse, expiration or termination of any such Awards prior to issuance of
the shares or the payment of the equivalent or if shares are issued under such
Stock Options or Stock Appreciation Rights or as Stock Awards, and thereafter
are reacquired by the Company pursuant to rights reserved by the Company upon
issuance thereof.

    6.  STOCK OPTIONS.  Stock Options will consist of awards from the Company,
in the form of agreements, which will enable the holder to purchase a specific
number of Common Shares, at set terms and at a fixed purchase price. Stock
Options may be "incentive stock options" within the meaning of Section 422 of
the Internal Revenue Code ("Incentive Stock Options") or Stock Options which do
not constitute Incentive Stock Options ("Nonqualified Stock Options"). The
Committee will have the authority to grant to any participant one or more
Incentive Stock Options, Nonqualified Stock Options, or both types of Stock
Options (in each case with or without Stock Appreciation Rights). Each Stock
Option shall be

                                      F-1
<PAGE>
subject to such terms and conditions consistent with the Plan as the Committee
may impose from time to time, subject to the following limitations:

        (a)  EXERCISE PRICE.  Each Stock Option granted hereunder shall have
    such per-share exercise price as the Committee may determine at the date of
    grant provided, however, that the per-share exercise price for Incentive
    Stock Options shall not be less than 100% of the Fair Market Value of the
    Common Shares on the date the option is granted and provided further that
    the per-share exercise price for Nonqualified Stock Options shall not be
    less than 85% of the Fair Market Value of the Common Shares on the date the
    option is granted.

        (b)  PAYMENT OF EXERCISE PRICE.  The option exercise price may be paid
    by check or, in the discretion of the Committee, by the delivery (or
    certification of ownership) of Common Shares of the Company then owned by
    the participant; provided, however, that option agreements may provide that
    payment of the exercise price by delivery of Common Shares of the Company
    then owned by the participant may be made only if such payment does not
    result in a charge to earnings for financial accounting purposes as
    determined by the Committee. In the discretion of the Committee, if Common
    Shares are readily tradeable on a national securities exchange or other
    market system at the time of option exercise, payment may also be made by
    delivering a properly executed exercise notice to the Company together with
    a copy of irrevocable instructions to a broker to deliver promptly to the
    Company the amount of sale or loan proceeds to pay the exercise price. To
    facilitate the foregoing, the Company may enter into agreements for
    coordinated procedures with one or more brokerage firms.

        (c)  EXERCISE PERIOD.  Stock Options granted under the Plan shall be
    exercisable at such times and subject to such terms and conditions as shall
    be determined by the Committee. In addition, Nonqualified Stock Options
    shall not be exercisable later than fifteen (15) years after the date they
    are granted and Incentive Stock Options shall not be exercisable later than
    ten (10) years after the date they are granted. All Stock Options shall
    terminate at such earlier times and upon such conditions or circumstances as
    the Committee shall in its discretion set forth in such option at the date
    of grant.

        (d)  LIMITATIONS ON INCENTIVE STOCK OPTIONS.  Incentive Stock Options
    may be granted only to participants who are employees of the Company or one
    of its subsidiaries (within the meaning of Section 424(f) of the Internal
    Revenue Code) at the date of grant. The aggregate Fair Market Value
    (determined as of the time of the option is granted) of the Common Shares
    with respect to which Incentive Stock Options are exercisable for the first
    time by a participant during any calendar year (under all option plans of
    the Company) shall not exceed $100,000. Incentive Stock Options may not be
    granted to any participant who, at the time of grant, owns stock possessing
    (after the application of the attribution rules of Section 424(d) of the
    Code) more than 10% of the total combined voting power of all classes of
    stock of the Company, unless the option price is fixed at not less than 110%
    of the Fair Market Value of the Common Shares on the date of grant and the
    exercise of such option is prohibited by its terms after the expiration of
    five (5) years from the date of grant of such option.

        (e)  REDESIGNATION AS NONQUALIFIED STOCK OPTIONS.  Options designated as
    "incentive stock options" that fail to continue to meet the requirements of
    Section 422 of the Internal Revenue Code shall be redesignated as
    nonqualified options for Federal income tax purposes automatically without
    further action by the Committee on the date of such failure to continue to
    meet the requirements of Section 422 of the Code.

        (f)  LIMITATION OF RIGHTS IN SHARES.  The recipient of a Stock Option
    shall not be deemed for any purpose to be a shareholder of the Company with
    respect to any of the shares subject thereto except to the extent that the
    Stock Option shall have been exercised and, in addition, a certificate shall
    have been issued and delivered to the participant.

                                      F-2
<PAGE>
        (g)  INDIVIDUAL LIMITATION ON NUMBER OF SHARES.  The number of shares
    subject to Stock Options which may be granted during any calendar year to
    any one participant shall not exceed One Hundred Thousand (100,000) shares.

    7.  STOCK APPRECIATION RIGHTS.  The Committee may, in its discretion, grant
Stock Appreciation Rights to the holders of any Stock Options granted hereunder.
In addition, Stock Appreciation Rights may be granted independently of and
without relation to options. The number of shares subject to Stock Appreciation
Rights which may be granted during any calendar year to any one participant
shall not exceed Twenty One Thousand (21,000) shares. Each Stock Appreciation
Right shall be subject to such terms and conditions consistent with the Plan as
the Committee shall impose from time to time, including the following:

        (a) A Stock Appreciation Right relating to a Nonqualified Stock Option
    may be made part of such option at the time of its grant or at any time
    thereafter up to six months prior to its expiration, and a Stock
    Appreciation Right relating to an Incentive Stock Option may be made part of
    such option only at the time of its grant.

        (b) Each Stock Appreciation Right will entitle the holder to elect to
    receive the appreciation in the Fair Market Value of the shares subject
    thereto up to the date the right is exercised. In the case of a right issued
    in relation to a Stock Option, such appreciation shall be measured from not
    less than the option price and in the case of a right issued independently
    of any Stock Option, such appreciation shall be measured from not less than
    85% of the Fair Market Value of the Common Shares on the date the right is
    granted. Payment of such appreciation shall be made in cash or in Common
    Shares, or a combination thereof, as set forth in the award, but no Stock
    Appreciation Right shall entitle the holder to receive, upon exercise
    thereof, more than the number of Common Shares (or cash of equal value) with
    respect to which the right is granted.

        (c) Each Stock Appreciation Right will be exercisable at the times and
    to the extent set forth therein, but no Stock Appreciation Right may be
    exercisable earlier than six months after the date it was granted or later
    than the earlier of (i) the term of the related option, if any, or
    (ii) fifteen years after it was granted. Exercise of a Stock Appreciation
    Right shall reduce the number of shares issuable under the Plan (and the
    related option, if any) by the number of shares with respect to which the
    right is exercised.

    8.  STOCK AWARDS.  Stock Awards will consist of Common Shares transferred to
participants for a consideration equal to the Fair Market Value per share, at a
discount from Fair Market Value, or without other payment therefor as additional
compensation for services rendered to the Company. Stock Awards shall be subject
to such terms and conditions as the Committee determines appropriate, including,
without limitation, restrictions on the sale or other disposition of such shares
and rights of the Company to reacquire such shares for no consideration upon
termination of the participant's employment within specified periods. The
Committee may require the participant to deliver a duly signed stock power,
endorsed in blank, relating to the Common Shares covered by any Stock Award. The
Committee may also require that the stock certificates evidencing such shares be
held in custody until the restrictions thereon shall have lapsed. Subject to the
restrictions set forth in any such Stock Award, the participant shall have, with
respect to the Common Shares subject to a Stock Award, all of the rights of a
holder of Common Shares of the Company, including the right to receive dividends
and to vote the shares.

    9.  PERFORMANCE SHARES

        (a) Performance Shares may be awarded either alone or in addition to
    other Awards granted under this Plan and shall consist of the right to
    receive Common Shares or cash of an equivalent value at the end of a
    specified Performance Period. The Committee shall determine the participants
    to whom and the time or times at which Performance Shares shall be awarded,
    the number of Performance Shares to be awarded to any person, the duration
    of the period (the "Performance

                                      F-3
<PAGE>
    Period") during which, and the conditions under which, receipt of the Common
    Shares will be deferred, and the other terms and conditions of the Award in
    addition to those set forth in this Section 9. The Committee may condition
    the grant of Performance Shares upon the attainment of specified performance
    goals or such other factors or criteria as the Committee shall determine.

        (b) Performance Shares awarded pursuant to this Section 9 shall be
    subject to the following terms and conditions:

           (i) Unless otherwise determined by the Committee at the time of the
       grant a Performance Share Award, with respect to the Common Shares
       subject to a Performance Share Award, the participant shall not have any
       of the rights of a holder of Common Shares of the Company, including the
       right to receive dividends or to vote the shares.

           (ii) Subject to the provisions of the Performance Share Award and
       this Plan, at the expiration of the Performance Period, share
       certificates and/or cash of an equivalent value (as the Committee may
       determine) shall be delivered to the participant, or his or her legal
       representative, in a number equal to the vested shares covered by the
       Performance Share Award.

          (iii) Subject to the applicable provisions of the Performance Share
       Award and this Plan, upon termination of a participant's employment with
       the Company for any reason during the specified Performance Period, the
       participant's Performance Shares will vest or be forfeited in accordance
       with the terms and conditions established by the Committee.

    10.  PERFORMANCE UNITS.

        (a) Performance Units may be awarded either alone or in addition to
    other Awards granted under this Plan and shall consist of the right to
    receive a fixed dollar amount, payable in cash or Common Shares or a
    combination of both. The Committee shall determine the participants to whom
    and the time or times at which Performance Units shall be awarded, the
    number of Performance Units to be awarded to any person, the duration of the
    period (the "Performance Cycle") during which, and the conditions under
    which, a participant's right to Performance Units will be vested, the
    ability of participants to defer the receipt of payment of such Performance
    Units, and the other terms and conditions of the Award in addition to those
    set forth in Section 10. The Committee may condition the vesting of
    Performance Units upon the attainment of specified performance goals or such
    other factors or criteria as the Committee shall determine.

        (b) The Performance Units awarded pursuant to this Section 10 shall be
    subject to the following terms and conditions:

           (i) At the expiration of the Performance Cycle, the Committee shall
       determine the extent to which the performance goals have been achieved,
       and the percentage of the Performance Units of each participant that have
       vested.

           (ii) Subject to the applicable provisions of the Performance Unit
       Award and this Plan, at the expiration of the Performance Cycle, cash
       and/or share certificates of an equivalent value (as the Committee may
       determine) shall be delivered to the participant, or his or her legal
       representative, in payment of the vested Performance Units covered by the
       Performance Unit Award.

          (iii) Subject to the applicable provisions of the Performance Unit
       Award and this Plan, upon termination of a participant's employment with
       the Company for any reason during the Performance Cycle for a given
       Performance Unit Award, the Performance Units in question will vest or be
       forfeited in accordance with the terms and conditions established by the
       Committee.

    11.  ADJUSTMENT PROVISIONS.

        (a) If the Company shall at any time change the number of issued Common
    Shares without new consideration to the Company (such as by stock dividend,
    stock split, recapitalization, reorganization, exchange or shares,
    liquidation, combination or other change in corporate structure affecting
    the Common Shares) or make a distribution of cash or property which has a
    substantial impact on the value of issued Common Shares, the total number of
    shares available for Awards under this Plan shall be appropriately adjusted
    and the number of shares covered by each outstanding Award and the reference
    price or Fair Market Value for each outstanding Award shall be adjusted so
    that the net value of such Award shall not be changed.

        (b) In the case of any sale of assets, merger, consolidation,
    combination or other corporate reorganization or restructuring of the
    Company with or into another corporation which results in the outstanding
    Common Shares being converted into or exchanged for different securities,
    cash or other property, or any combination thereof (an "Acquisition"),
    subject to the provisions of this Plan and any limitation applicable to the
    Award:

           (i) any participant to whom a Stock Option has been granted shall
       have the right thereafter and during the term of the Stock Option, to
       receive upon exercise thereof the Acquisition Consideration (as defined
       below) receivable upon the Acquisition by a holder of the number of
       Common Shares which might have been obtained upon exercise of the Stock
       Option or portion thereof, as the case may be, immediately prior to the
       Acquisition;

           (ii) any participant to whom a Stock Appreciation Right has been
       granted shall have the right thereafter and during the term of such right
       to receive upon exercise therof the difference on the exercise date
       between the aggregate Fair Market Value of the Acquisition Consideration
       receivable upon such acquisition by a holder of the number of Common
       Shares which are covered by such right and the aggregate reference price
       of such right; and

          (iii) any participant to whom Performance Shares or Performance Units
       have been awarded shall have the right thereafter and during the term of
       the Award, upon fulfillment of the terms of the Award, to receive on the
       date or dates set forth in the Award, the Acquisition Consideration
       receivable upon the Acquisition by a holder of the number of Common Share
       which are covered by the Award.

        The term "Acquisition Consideration" shall mean the kind and amount of
    securities, cash or other property or any combination thereof receivable in
    respect of one Common Share upon consummation of an Acquisition.

        (c) Notwithstanding any other provision of this Plan, the Committee may
    authorize the issuance, continuation or assumption of Awards or provide for
    other equitable adjustments after changes in the Common Shares resulting
    from any other merger, consolidation, sale of assets, acquisition of
    property or stock, recapitalization, reorganization or similar occurrence
    upon such terms and conditions as it may deem equitable and appropriate.

        (d) In the event that another corporation or business entity is being
    acquired by the Company, and the Company assumes outstanding employee stock
    options and/or stock appreciation rights and/ or the obligation to make
    future grants of options or rights to employees of the acquired entity, the
    aggregate number of Common Shares available for Awards under this Plan shall
    be increased accordingly.

    12.  NONTRANSFERABILITY.


        (a) Each Award granted under the Plan to a participant shall not be
    transferable by him otherwise than by law or by will or the laws of descent
    and distribution, and shall be exercisable, during his lifetime, only by
    him. In the event of the death of a participant while the participant is


                                      F-5
<PAGE>

    rendering services to the Company, each Stock Option or Stock Appreciation
    Right theretofore granted to him shall be exercisable during such period
    after his death as the Committee shall in its discretion set forth in such
    option or right at the date of grant (but not beyond the stated duration of
    the option or right) and then only:


           (i) By the executor or administrator of the estate of the deceased
       participant or the person or persons to whom the deceased participant's
       rights under the Stock Option or Stock Appreciation Right shall pass by
       will or the laws of descent and distribution; and

           (ii) To the extent that the deceased participant was entitled to do
       so at the date of his death.

        (b) Notwithstanding Section 12(a), in the discretion of the Committee,
    Awards granted hereunder may be transferred to members of the participant's
    immediate family (which for purposes of this Plan shall be limited to the
    participant's children, grandchildren and spouse), or to one or more trusts
    for the benefit of such family members or partnerships in which such family
    members and/or trusts are the only partners, but only if the Award expressly
    so provides.

    13.  OTHER PROVISIONS.  Awards under the Plan may also be subject to such
other provisions (whether or not applicable to any other Awards under the Plan)
as the Committee determines appropriate, including without limitation,
provisions for the installment purchase of Common Shares under Stock Options,
provisions for the installment exercise of Stock Appreciation Rights, provisions
to assist the participant in financing the acquisition of Common Shares,
provisions for the forfeiture of, or restrictions on resale or other disposition
of Shares acquired under any form of Award, provisions for the acceleration of
exercisability or vesting of Awards in the event of a change of control of the
Company, provisions for the payment of the value of Awards to participants in
the event of a change of control of the Company, provisions for the forfeiture
of, or provisions to comply with Federal and state securities laws, or
understandings or conditions as to the participant's employment in addition to
those specifically provided for under the Plan.

    14.  FAIR MARKET VALUE.  For purposes of this Plan and any Awards hereunder,
the Fair Market Value of Common Shares shall be the mean between the highest and
lowest sale prices for the Company's Common Shares as reported on the NASDAQ
National Market System (or such other consolidated transaction reporting system
on which such Common Shares are primarily traded) on the date of calculation (or
on the next preceding trading date if Common Shares were not traded on the date
of calculation), provided, however, that if the Company's Common Shares are not
at any time readily tradeable on a national securities exchange or other market
system, Fair Market Value shall mean the amount determined in good faith by the
Committee as the fair market value of the Common Shares of the Company.

    15.  WITHHOLDING.  All payments or distributions made pursuant to the Plan
shall be net of any amounts required to be withheld pursuant to applicable
federal, state and local income and/or employment tax withholding requirements.
If the Company proposes or is required to distribute Common Shares pursuant to
the Plan, it may require the recipient to remit to it an amount sufficient to
satisfy such tax withholding requirements prior to the delivery of any
certificates for such Common Shares. The Committee may, in its discretion and
subject to such rules as it may adopt, permit an optionee or award or right
holder to pay all or a portion of the federal, state and local withholding taxes
arising in connection with (a) the exercise of a Nonqualified Stock Option or a
Stock Appreciation Right, (b) the receipt or vesting of Stock Awards, or
(c) the receipt of Common Shares upon the expiration of the Performance Period
or the Performance Cycle, respectively, with respect to any performance Shares
or Performance Units, by electing to have the Company withhold Common Shares
having a Fair Market Value equal to the amount of taxes required to be withheld.

    16.  TENURE.  A participant's right, if any, to continue to serve the
Company as an officer, employee, or otherwise, shall not be enlarged or
otherwise affected by his designation as a participant under the Plan,

                                      F-6
<PAGE>
nor shall this Plan in any way interfere with the right of the Company, subject
to the terms of any separate employment agreement to the contrary, at any time
to terminate such employment or to increase or decrease the compensation of the
participant from the rate in existence at the time of the grant of an Award.

    17.  DURATION, AMENDMENT AND TERMINATION.  No Award shall be granted after
July 1, 2005; provided, however, that the terms and conditions applicable to any
Award granted prior to such date may thereafter be amended or modified by mutual
agreement between the Company and the participant or such other persons as may
then have an interest therein. Also, by mutual agreement between the Company and
a participant, under this Plan or under any other present or future plan of the
Company, Awards may be granted to such participant in substitution and exchange
for, an in cancellation of, any Awards previously granted such participant under
this Plan, or any other present or future plan of the Company. The Board of
Directors may amend the Plan from time to time or terminate the Plan at any
time. However, no action authorized by this Section 17 shall reduce the amount
of any existing Award or change the terms and conditions thereof without the
participant's consent. No amendment of the Plan shall, without approval of the
shareholders of the Company, (i) result in any member of the Committee losing
his or her status as a disinterested person under Securities and Exchange
Commission Regulation Section240.16b-3; or (ii) result in the Plan losing its
status as a protected plan under the Securities and Exchange Commission
Rule 16b-3.

    18.  GOVERNING LAW.  This Plan and actions taken in connection herewith
shall be governed and construed in accordance with the laws of the State of
Illinois (regardless of the law that might otherwise govern under applicable
Illinois principles of conflict of laws).

    19.  APPROVAL.  The Plan was adopted by the Board of Directors and the
shareholders of the Company on December 29, 1995.

                                      F-7

USWeb/CKS Corporation
2880 Lakeside Drive, Suite 300
Santa Clara, CA 95054

Ladies and Gentlemen:

     We have acted as counsel to USWeb/CKS Corporation, a Delaware
corporation (the "Company") in connection with the proposed merger (the
"Merger") among Whittman-Hart, Inc., a Delaware corporation ("Parent"),
Uniwhale, a Delaware corporation and wholly-owned transitory merger
subsidiary of Parent ("Merger Sub"), and the Company pursuant to an Agreement
and Plan of Merger dated as of December 12, 1999, (the "Merger Agreement").
The Merger and certain proposed transactions incident thereto are described
in the Registration Statement on Form S-4 (the "Registration Statement") of
Parent which includes the Proxy Statement/Prospectus of the Company (the
"Proxy Statement/Prospectus"). This opinion is being rendered pursuant to the
requirements of Item 21(a) of Form S-4 under the Securities Act of 1933, as
amended. Unless otherwise indicated, any capitalized terms used herein and
not otherwise defined have the meaning ascribed to them in the Proxy
Statement/Prospectus.

    In connection with this opinion, we have examined and are familiar with
the Merger Agreement, the Registration Statement, and such other presently
existing documents, records and matters of law as we have deemed necessary or
appropriate for purposes of our opinion. In addition, we have assumed (i)
that the Merger will be consummated in the manner contemplated by the Proxy
Statement/Prospectus and in accordance with the provisions of the Merger
Agreement, (ii) the truth and accuracy of the representations and warranties
made by Parent, Merger Sub and the Company in the Merger Agreement, and (iii)
the truth and accuracy of the certificates of representations provided to us
by Parent, Merger Sub and the Company.

     Based upon and subject to the foregoing, in our opinion, the discussion
contained in the Registration Statement under the caption "Approval of the
Merger -- Certain Federal Income Tax Consequences," subject to the limitations
and qualifications described therein, sets forth the material United States
Federal income tax considerations generally applicable to the Merger.
Because this opinion is being delivered prior to the Effective Time of the
Merger, it must be considered prospective and dependent on future events.
There can be no assurance that changes in the law will not take place which
could affect the United States Federal income tax consequences of the Merger
or that contrary positions may not be taken by the Internal Revenue Service.

to our firm name wherever appearing in the Registration Statement with
respect to the discussion of the material federal income tax consequences of
the Merger, including the Proxy Statement/Prospectus constituting a part
thereof, and any amendment thereto. In giving this consent, we do not
thereby admit that we are in the category of persons whose consent is
required under Section 7 of the Securities Act of 1933, as amended, or the
rules and regulations of the Securities and Exchange Commission thereunder,
nor do we thereby admit that we are experts with respect to any part of such

WHITTMAN-HART, INC.
311 S. Wacker Drive, Suite 3500
Chicago, Illinois 60606-6618
Attention: Board of Directors

Ladies and Gentlemen:

We have been requested to render this opinion concerning certain material
federal income tax consequences in connection with the proposed merger of
UNIWHALE, INC., a newly formed corporation, organized and existing under the
laws of the State of Delaware ("Merger Sub") which is wholly owned by
WHITTMAN-HART, INC., a corporation organized and existing under the laws of
the Delaware ("Parent"), with and into USWEB/CKS CORPORATION, a corporation
organized and existing under the laws of the State of Delaware (the
"Company"), with the Company surviving the merger and becoming a wholly owned
subsidiary of Parent, pursuant to the applicable corporate law of the State
of Delaware (the "Merger"), and in accordance with that certain Agreement and
Plan of Merger dated as of December 12, 1999, among the Company, Parent and
Merger Sub (the "Agreement") and related documents and agreements referenced
in the Agreement (together with the Agreement, the "Merger Agreement"). Our
opinion is being delivered to you pursuant to Section 7.1(d) of the Agreement.

Except as otherwise provided, capitalized terms referred to herein have the
meanings set forth in the Merger Agreement. All section references, unless
otherwise indicated, are to the Internal Revenue Code of 1986, as amended
(the "Code").

We have acted as legal counsel to the Parent in connection with the Merger.
As such, and for the purpose of rendering this opinion, we have examined (or
will examine on or prior to the Effective Time of the Merger) and are relying
(or will rely) upon (without any independent investigation or review thereof)
the truth and accuracy, at all relevant times, of the statements, covenants,
representations and warranties contained in the following documents
(including all schedules and exhibits thereto):

     1.    The Merger Agreement.

     2.    Representations made to us by Parent and Merger Sub, including
           those representations contained in the Parent Tax Certificate
           dated January 11, 2000.

     3.    Representations made to us by the Company, including those
           representations contained in the Company Tax Certificate dated
           January 25, 2000.

     4.    Parent's Registration Statement on Form S-4, filed January 26,
           2000.

     5.    Such other instruments and documents related to the formation,
           organization and operation of the Company, Parent and Merger Sub
           or the consummation of the Merger and the transactions
           contemplated by the Merger Agreement as we have deemed necessary
           or appropriate.

OPINION

In connection with rendering this opinion, we have assumed or obtained
representations (and are relying thereon, without any independent
investigation or review thereof) including that:

     1.    Original documents (including signatures) are authentic; documents
           submitted to us as copies conform to the original documents, and
           there has been (or will be by the Effective Time of the Merger)
           due execution and delivery of all documents where due execution
           and delivery are prerequisites to the effectiveness thereof.

     2.    Any representation or statement referred to above made "to the
           knowledge of" or otherwise similarly qualified is correct without
           such qualification.

     3.    The Merger will be consummated pursuant to the Merger Agreement
           and will be effective under the applicable state law.

     4.    After the Merger, the Company will hold "substantially all" of its
           and Merger Sub's properties within the meaning of Section
           368(a)(2)(E)(i) of the Code and the regulations promulgated
           thereunder.

     5.    Following the Merger, the Company will continue its historic
           business or use a significant portion of its historic business
           assets in a business.

     6.    No outstanding indebtedness of the Company, Parent or Merger Sub
           has represented or will represent equity for tax purposes
           (including, without limitation, any loans from Parent to the
           Company); no outstanding equity of the Company, Parent or Merger
           Sub has represented or will represent indebtedness for tax
           purposes; no outstanding security (other than the Company Option
           Plans), instrument, agreement or arrangement that provides for,
           contains, or represents either a right to acquire the Company
           stock or to share in the appreciation thereof constitutes or will
           constitute "stock" for purposes of Section 368(c) of the Code.

WHITTMAN-HART, INC.

     7.    Each of Company, Parent and Merger Sub has paid and will pay only
           its respective expenses, if any, incurred in connection with the
           Merger, and neither Parent, Merger Sub nor Company has agreed to
           assume, nor will it directly or indirectly assume, any expense or
           other liability, whether fixed or contingent, of any holder of
           Company Common Stock.

     8.    Neither Parent, the Company nor Merger Sub is, or will be at the
           time of the Merger: (a) an "investment company" within the meaning
           of Section 368(a)(2)(F) of the Code; or (b) under the jurisdiction
           of a court in a Title 11 or similar case within the meaning of
           Section 368(a)(3)(A) of the Code.

Based on our examination of the foregoing items and subject to the
assumptions, exceptions, limitations and qualifications set forth herein, it
is our opinion, as legal counsel for Parent, that for federal income tax
purposes:

           (i)   the Merger will constitute a "reorganization" within the
                 meaning of Section 368(a) of the Code, and the Company,
                 Merger Sub and Parent will each be a party to such
                 reorganization within the meaning of Section 368(b) of the
                 Code;

           (ii)  no gain or loss will be recognized by Company, Parent, or
                 Merger Sub as a result of the Merger;

           (iii) no gain or loss will be recognized by the stockholders of
                 the Company upon the exchange of their Company Common Stock
                 solely for shares of Parent Common Stock pursuant to the
                 Merger, except with respect to cash, if any, received in
                 lieu of fractional shares of Parent Common Stock;

           (iv)  the aggregate tax basis of the shares of Parent Common Stock
                 received solely in exchange for Company Common Stock
                 pursuant to the Merger (including fractional shares of
                 Parent Common Stock for which cash is received) will be the
                 same as the aggregate tax basis of the Company Common Stock
                 exchanged therefor;

           (v)   the holding period for shares of Parent Common Stock
                 received solely in exchange for Company Common Stock
                 pursuant to the Merger will include the holding period of
                 the Company Common Stock exchanged therefor, provided such
                 Company Common Stock was held as a capital asset by the
                 stockholder at the Effective Time; and


<PAGE>

WHITTMAN-HART, INC.
January 26, 2000
Page 4

           (vi)  a stockholder of the Company who receives cash in lieu of a
                 fractional share of Parent Common Stock will recognize gain
                 or loss equal to the difference, if any, between such
                 stockholder's tax basis in such fractional share (as
                 described in clause (iv) above) and the amount of cash
                 received.

QUALIFICATIONS

In addition to the assumptions set forth above, this opinion is subject to
the exceptions, limitations and qualifications set forth below:

     1.    This opinion represents and is based upon our best judgment
           regarding the application of federal income tax laws arising under
           the Code, existing judicial decisions, administrative regulations
           and published rulings and procedures. Our opinion is not binding
           upon the Internal Revenue Service or the courts, and the Internal
           Revenue Service is not precluded from asserting a contrary
           position. Furthermore, no assurance can be given that future
           legislative, judicial or administrative changes, on either a
           prospective or retroactive basis, would not adversely affect the
           accuracy of the opinion expressed herein. Nevertheless, we
           undertake no responsibility to advise you of any new developments
           in the application or interpretation of the federal income tax
           laws.

     2.    Our opinion concerning certain of the federal tax consequences of
           the Merger is limited to the specific federal tax consequences
           presented above. No opinion is expressed as to any transaction
           other than the Merger, including any transaction undertaken in
           connection with the Merger. In addition, this opinion does not
           address any other federal, estate, gift, state, local or foreign
           tax consequences that may result from the Merger. In particular,
           we express no opinion regarding:

           (a)   whether and the extent to which any Company stockholder who
                 has provided or will provide services to the Company, Parent
                 or Merger Sub will have compensation income under any
                 provision of the Code;

           (b)   the effects of such compensation income, including, but not
                 limited to, the effect upon the basis and the holding period
                 of the Parent Stock received by any such stockholder in the
                 Merger;

           (c)   the potential application of the "disqualifying disposition"
                 rules of Section 421 of the Code to dispositions of the
                 Company Common Stock;


<PAGE>

WHITTMAN-HART, INC.
January 26, 2000
Page 5

           (d)   the tax consequences of Parent's assumption of outstanding
                 options to acquire the Company Common Stock on the holders
                 of such options under any Company employee stock option or
                 stock purchase plan;

           (e)   the effects of the Merger on any pension or other employee
                 benefit plan maintained by Parent or the Company;

           (f)   the potential application of the "golden parachute"
                 provisions of Sections 280G, 3121(v)(2) and 4999 of the
                 Code, the alternative minimum tax provisions of Sections 55,
                 56 and 57 of the Code or Sections 108, 305, 306, 357 and 424
                 of the Code, or the regulations promulgated thereunder;

           (g)   the survival and/or availability, after the Merger, of any
                 of the federal income tax attributes or elections of the
                 Company or Parent (including, without limitation, foreign
                 tax credits or net operating loss carryforwards, if any, of
                 the Company or Parent), after application of any provision
                 of the Code, as well as the regulations promulgated
                 thereunder and judicial interpretations thereof;

           (h)   the basis of any equity interest in the Company acquired by
                 Parent in the Merger;

           (i)   the tax consequences of any transaction in which Company
                 Common Stock or a right to acquire Company Common Stock was
                 received; and

           (j)   the tax consequences of the Merger (including the opinion
                 set forth above) as applied to holders of options or
                 warrants to purchase Company Common Stock or that may be
                 relevant to particular classes of the Company stockholders
                 and/or holders of options or warrants for the Company Common
                 Stock, including, without limitation, dealers in securities,
                 corporate shareholders subject to the alternative minimum
                 tax, foreign persons, and holders of shares acquired upon
                 exercise of stock options or in other compensatory
                 transactions.

     3.    No opinion is expressed if all the transactions described in the
           Merger Agreement are not consummated in accordance with the terms
           of such Merger Agreement and without waiver or breach of any
           material provision thereof or if all of the representations,
           warranties, statements and assumptions upon which we relied are
           not true and accurate at all relevant times. In the event any one
           of the statements, representations, warranties or assumptions upon
           which we have relied to issue this


<PAGE>

WHITTMAN-HART, INC.
January 26, 2000
Page 6

           opinion is incorrect, our opinion might be adversely affected and
           may not be relied upon.

     4.    No ruling has been or will be requested from the Internal Revenue
           Service concerning the federal income tax consequences of the
           Merger. In reviewing this opinion, you should be aware that the
           opinion set forth above represents our conclusions regarding the
           application of existing federal income tax law to the instant
           transaction. If the facts vary from those relied upon (including
           if any representation, covenant, warranty or assumption upon which
           we have relied is inaccurate, incomplete, breached or
           ineffective), our opinion contained herein could be inapplicable.
           You should be aware that an opinion of counsel represents only
           counsel's best legal judgment, and has no binding effect or
           official status of any kind, and that no assurance can be given
           that contrary positions will not be taken by the Internal Revenue
           Service or that a court considering the issues would not hold
           otherwise.

     5.    This opinion is being delivered solely for the purpose of
           satisfying the condition set forth in Section 7.1(d) of the Merger
           Agreement. This opinion may not be relied upon or utilized for any
           other purpose or by any other person or entity, including the
           Company and its stockholders, and may not be made available to any
           other person or entity, without our prior written consent. We do,
           however, consent to the use of our name in the Registration
           Statement wherever it appears.


                                         Very truly yours,
