    AppNet provides Internet and electronic commerce professional services and
solutions to medium-sized and large businesses. AppNet develops electronic
commerce solutions that facilitate and promote communication and commerce
between businesses and consumers as well as among businesses and their trading
partners. We focus on maximizing the opportunities presented by the Internet and
electronic commerce to enhance all aspects of our clients' operations, from the
front end of their business, creative Website design, to the back end,
back-office integration of existing systems and electronic commerce outsourcing,
creating an end-to-end solution. Our professional services include:


    - strategic consulting;

    - interactive media services such as creative Website design and
      development, branding, which is the creation of a unique corporate
      identity for a client and its products, media planning and buying;

    - Internet-based application development, which is the development of
      software applications that are capable of running on the Internet and are
      written in languages such as Java, C++ and Visual Basic;

    - electronic commerce systems integration, which is the integration of
      electronic commerce systems, which are systems that automate the receipt,
      processing and delivery of transaction data and other information, with
      other corporate software and computer-based applications; and

    - electronic commerce outsourcing, which is the performance of electronic
      commerce services that would otherwise be handled by the client's internal
      staff using the client's resources.

    The rapid growth in the use of the Internet and electronic commerce has
transformed the way businesses operate and interact with their customers and
trading partners. Technology industry research firms predict that the market for
Internet and electronic commerce services worldwide will grow significantly over
the next few years. International Data Corporation estimates that this market
will increase from $4.6 billion in 1997 to $43.7 billion by 2002, which
represents a compound annual growth rate of 57%.

    Over the past several years, we have completed more than 500 projects for
over 200 clients. Our client base is highly diverse and includes corporations
such as @rts @lliance, Baxter Healthcare, Ciena, Comshare, Dial, Ford,
GeoCities, Harmony House, Hyundai, K*B Toys, NEC, Norwest and Unilever.


    AppNet was founded in late 1997 and, therefore, we have a brief operating
history upon which you can evaluate our business and prospects. We have incurred
substantial losses since AppNet was founded, and we anticipate we will continue
to incur substantial losses for the forseeable future. See "Risk Factors--Our
brief operating history makes it difficult to predict our success" and "Risk
Factors--We have an accumulated deficit of $30.7 million and anticipate future
losses."



    We compete in the highly competitive markets for Internet and electronic
commerce professional services. To compete more effectively, we plan to: expand
our client relationships; increase repeat and recurring revenues; build and
enhance complementary skill sets and maintain our technological


                                       1
<PAGE>
expertise; expand and strengthen our marketing and technology relationships with
leading technology vendors; pursue client-driven geographic expansion; expand
and develop industry-specific expertise; and attract and retain a highly
specialized workforce.

    We currently have offices in 14 U.S. locations, including the metropolitan
areas of Boston, Denver, Detroit, Los Angeles, New York and Washington, DC. Our

                                  RISK FACTORS

    INVESTING IN OUR COMMON STOCK INVOLVES RISK. YOU SHOULD CAREFULLY CONSIDER
THE RISKS DESCRIBED BELOW AND THE OTHER INFORMATION IN THIS PROSPECTUS,
INCLUDING OUR CONSOLIDATED FINANCIAL STATEMENTS AND THE RELATED NOTES, BEFORE
YOU PURCHASE ANY OF OUR COMMON STOCK. THE RISKS AND UNCERTAINTIES DESCRIBED
BELOW ARE NOT THE ONLY ONES WE FACE. ADDITIONAL RISKS AND UNCERTAINTIES,
INCLUDING THOSE THAT WE DO NOT KNOW ABOUT NOW OR THAT WE CURRENTLY DEEM
IMMATERIAL, MAY ALSO ADVERSELY AFFECT OUR BUSINESS.

OUR BRIEF OPERATING HISTORY MAKES IT DIFFICULT TO PREDICT OUR SUCCESS.

    AppNet was formed in late 1997. We have a brief operating history upon which
you can evaluate our business and prospects. Our historical results of
operations do not fully give effect to the operations of the companies we have
acquired and the pro forma financial information included in this prospectus is
based in part on the separate pre-acquisition financial information of the
acquired companies. As a result, our historical results of operations and pro
forma financial information may not give you an accurate indication of our
future results of operations or prospects. Companies like us in an early stage
of development frequently encounter risks, expenses and difficulties associated
with starting a new business, many of which may be beyond their control. These
risks and difficulties apply particularly to AppNet because our markets,
Internet and electronic commerce professional services, are new and rapidly
changing.

WE HAVE AN ACCUMULATED DEFICIT OF $30.7 MILLION AND ANTICIPATE FUTURE LOSSES.

    We have incurred substantial losses since AppNet was founded, and we
anticipate we will continue to incur substantial losses for the foreseeable
future. We had an accumulated deficit of approximately $30.7 million as of March
31, 1999 and a net loss of $14.4 million and $16.3 million for the year ended
December 31, 1998 and the quarter ended March 31, 1999, respectively. We intend
to continue to invest in internal expansion, infrastructure, integration of our
acquired companies into our existing operations, acquisitions and our marketing
and sales efforts. We cannot predict when we will operate profitably, if at all.

    We cannot assure you that we will have earnings or cash flow sufficient to
cover our fixed charges or to comply with the financial covenants in our credit
facilities. In connection with the acquisitions we have completed, we expect to
continue to incur through the end of the year 2000, acquisition-related
compensation charges which will fluctuate based on the market price of our
common stock and the level of achievement of agreed-upon operating targets. In
addition, our acquisitions significantly increased our intangible assets, such
as goodwill, and the charges we expect to incur in connection with the
amortization of these intangible assets will have a material adverse impact on
our net income for the foreseeable future. See "--Our intangible assets
represent a significant portion of our assets; amortization of our intangible
assets will adversely impact our net income and we may never realize the full
value of our intangible assets" for a discussion of accounting treatment issues
regarding intangible assets that will affect our future results of operations.

QUARTER-TO-QUARTER FLUCTUATIONS IN OUR REVENUES AND OPERATING RESULTS COULD
  AFFECT THE MARKET PRICE OF OUR COMMON STOCK.

    Our revenues and operating results may vary from quarter-to-quarter as a
result of a number of factors including:

    - number, size and type of client engagements commenced or completed during
      a quarter;

    - effectiveness of integrating acquisitions with existing operations;

    - our ability to attract, train and retain skilled management, technical and
      creative personnel;

                                       4
<PAGE>
    - timing of acquisitions and related costs; and

    - timing and size of acquisition-related compensation charges which
      fluctuate based on the market price of our common stock.

    Because a high percentage of our expenses is fixed, such as compensation and
rent, any of the factors listed above could cause significant variations in our
operating results in any given quarter. Any decline in revenues or earnings or a
greater than expected loss for any quarter could materially adversely affect the
market price of our common stock, even if not reflective of any long-term
problems with our business.

OUR FUTURE SUCCESS DEPENDS ON OUR ABILITY TO EFFECTIVELY INTEGRATE ACQUIRED
  COMPANIES AND MANAGE OUR GROWTH.

    Our growth has placed, and will continue to place, significant demands on
our management and operational and financial resources. We have acquired 12
companies since March 1998. Our number of employees has increased from six as of
February 1, 1998 to approximately 755 as of May 1, 1999. We are in the process
of integrating the companies we have acquired since March 1998 into our
operational, financial and managerial systems. Members of our senior management
may be required to devote considerable amounts of their time to this integration
process, which will decrease the time they will have to service current clients,
attract new clients and develop new products and services. Our business,
financial condition and results of operations could be adversely affected if any
of the companies we have acquired experienced problems in the past of which we
are not currently aware. Claims asserted against us relating to the operation of
the companies we acquired prior to acquisition could exceed the indemnification
we are entitled to or can obtain from the former owners of the acquired
companies.

    As we continue to grow, we expect we will hire more employees and expand the
scope of our operating and financial systems, which will increase our operating
complexity and the level of responsibility exercised by our management
personnel. To manage our growth effectively, we must continue to develop and
improve our own operational and financial systems, including our internal
systems and controls as well as those of the companies we acquired. The failure
to manage our growth effectively could have a material adverse effect on our
business, financial condition and results of operations.

WE MUST ATTRACT AND RETAIN PROFESSIONAL STAFF IN ORDER TO COMPLETE OUR PROJECTS
  AND OBTAIN NEW PROJECTS.


    Our failure to attract and retain qualified employees could impair our
ability to complete existing projects and bid for or obtain new projects and, as
a result, could have a material adverse effect on our business, financial
condition and results of operations. Our ability to grow and increase our market
share largely depends on our ability to hire, train, retain and manage highly
skilled employees, including project managers and technical, creative,
consulting and marketing and sales personnel. There is a significant shortage
of, and intense competition for, personnel who are qualified to perform the
services we provide. This shortage will probably continue for the foreseeable
future. In addition, to maintain our position as a provider of Internet and
electronic commerce end-to-end solutions, we must make sure our employees
maintain their technical expertise and business skills. We cannot assure you
that we will be able to attract a sufficient number of qualified employees or
that we will successfully train and manage the employees we hire.


    In addition, our employees, including key technical personnel, may leave us
to join our competitors or start new businesses which may compete with us. We
cannot assure you that we will be able to prevent the unauthorized disclosure or
use of our proprietary knowledge, practices and procedures if our employees
leave us.

                                       5
<PAGE>
WE ARE DEPENDENT ON ADDITIONAL CAPITAL FOR FUTURE GROWTH.


    Our ability to remain competitive and expand our operations through
acquisitions and internal growth largely depends on our access to capital.
Historically, we have financed capital expenditures and acquisitions primarily
by incurring debt and issuing equity securities. We may incur additional debt
and issue equity securities in the future to finance our growth strategy or
capital expenditures. We cannot assure you that additional financing will be
available to us on satisfactory terms, or at all. Additional indebtedness would
make us more vulnerable to economic downturns and may limit our ability to
withstand competitive pressures. The terms of any additional indebtedness may
include restrictive financial and operating covenants which would limit our
ability to compete and expand. Additional issuances of our common stock may
significantly dilute the equity interests of our existing stockholders. Our
failure to obtain any required additional financing, on satisfactory terms, or
at all, could have a material adverse affect on our business, financial
condition or results of operations. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations" for a further discussion of our
liquidity and capital requirements over the next 18 months.


OUR REVENUES ARE DIFFICULT TO PREDICT BECAUSE THEY ARE PRIMARILY GENERATED ON A
  PROJECT-BY-PROJECT BASIS AND OUR PROJECTS CAN BE TERMINATED.


    If our existing agreements with clients are terminated before we complete
our engagements, or if we are unable to enter into new engagements, our
business, financial condition and results of operations could be materially
adversely affected. Our success will depend on our ability to establish
relationships with additional medium-sized and large businesses and other
corporate users of Internet and electronic commerce professional services. We
derive our revenues in large part from fees for services generated on a
project-by-project basis. These projects vary in size, scope and duration. A
client that accounts for a significant portion of our revenues in a particular
period may not account for a similar portion of our revenues in future periods.
A client may or may not engage us for further services once a project is
completed. As a result, our revenues are not recurring from period to period,
which makes them more difficult to predict.


OUR CONTRACTS CONTAIN PRICING RISKS.

    Generally, we charge our clients for the time, materials and expenses
incurred. Although we have limited experience pricing and managing fixed-price
contracts, we intend to increase the percentage of our work that is billed at a
fixed price. However, if we underestimate the resources and time required to
complete our projects, we could be subject to cost overruns leading to losses on
our engagements.

LOSS OF THE SERVICES OF OUR SENIOR MANAGEMENT COULD ADVERSELY AFFECT OUR
  BUSINESS.

    The loss of our senior managers' services or other key members of management
could have a material adverse effect on our business, financial condition and
results of operations. Our success depends heavily on the efforts of the members
of our senior management team. We cannot assure you that we will be able to
prevent the unauthorized disclosure or use of our proprietary knowledge,
practices and procedures if our senior managers leave us. See "Management" for
additional information about our senior managers.

WE FACE INTENSE COMPETITION.

    The markets for Internet and electronic commerce professional services are
relatively new, intensely competitive, quickly evolving and subject to rapid
technological change. We expect competition to continue and intensify in the
foreseeable future. Our competitors can be divided into several groups:

                                       6
<PAGE>
    - Internet professional services providers, such as Agency.com, iXL,
      Proxicom, Razorfish, Scient, Think New Ideas, US Interactive, USWeb/CKS
      and Viant;

    - large information technology consulting services providers, such as
      Andersen Consulting, Cambridge Technology Partners, CSC, EDS, IBM and
      Sapient;

    - interactive advertising agencies, such as Darwin Digital, Giant Step, Grey
      Interactive, Modem Media . Poppe Tyson and Thunderhouse;

    - electronic commerce software and service providers, such as BroadVision,
      Harbinger, Open Market and Sterling Commerce; and

    - Internet access and service providers, such as Abovenet, Exodus and
      Frontier/Global.

    Our competitors have begun to offer multiple Internet and electronic
commerce professional services, rather than specialize in one area, or have
announced their intention to do so. These companies may continue to expand their
operations so that they offer a full range of Internet and electronic commerce
professional services and products.

    Many of our competitors have longer operating histories and client
relationships, greater financial, technical, marketing and public relations
resources, larger client bases and greater brand or name recognition than we
have. Our competitors may be able to respond more quickly to technological
developments and changes in clients' needs. We must promote and enhance our
reputation and brand in order to attract new clients and differentiate ourselves
from our competitors. See "Business-- Competition" for a further discussion of
competition within our industry.

THE BARRIERS TO ENTER OUR BUSINESS ARE LOW.

    There are relatively low barriers to entry into our business. We do not own
any technologies that preclude or inhibit competitors from entering our markets.
Our competitors may independently develop and patent or copyright technologies
that are superior or substantially similar to our technologies. The costs to
develop and provide Internet or electronic commerce professional services are
low. Therefore, we expect to continue to face additional competition from new
entrants into our markets.

WE MUST RESPOND TO RAPID TECHNOLOGICAL ADVANCES.

    Our success will depend, in part, on our ability to keep pace with:

    - rapidly changing technology;

    - evolving industry standards and practices;

    - frequent new service and product introductions and enhancements; and

    - changing user and client requirements and preferences.

    Any delay or failure on our part in responding quickly, cost-effectively and
sufficiently to these developments could render our existing products and
services obsolete and have a material adverse effect on our business, financial
condition and results of operations. We may have to incur substantial
expenditures to modify or adapt our services or infrastructure to respond to the
widespread adoption of new Internet, networking or telecommunications
technologies or other technological changes. We must stay abreast of
cutting-edge technological developments and evolving service offerings to remain
competitive, increase the utility of our services and attract and retain
qualified employees. We must be able to incorporate new technologies into the
Internet and electronic commerce solutions we design and develop to address the
increasingly complex and varied needs of our customer base.

                                       7
<PAGE>
OUR BUSINESS IS DEPENDENT ON THE CONTINUED USE AND GROWTH OF THE INTERNET AND
  ELECTRONIC COMMERCE.

    Our business would be adversely affected if use of the Internet and
electronic commerce does not continue to develop, or develops more slowly than
expected. Our market is relatively new and rapidly evolving. Our future success
depends on the acceptance by current and future clients of Internet and
electronic commerce professional services as an integral part of their
businesses. Demand and market acceptance for these new technological services
are subject to a high level of uncertainty.

    In addition, if use of the Internet grows, the Internet infrastructure may
not be able to support the demands placed on it. The performance and reliability
of the Internet may decline as the number of users and the amount of traffic
increases. Internet sites have experienced interruptions in their service as a
result of outages and other delays occurring throughout the Internet network
infrastructure. To cope with growth in the use of the Internet, the Internet
will require a reliable network backbone with the necessary speed, data capacity
and security and the timely development of complementary products, such as
high-speed modems, for providing reliable Internet access and services. If the
necessary infrastructure, products, services or facilities are not developed or
if use of the Internet as a medium for communication and commerce does not
develop, our business, financial condition and results of operations could be
materially and adversely affected.

WE HAVE POTENTIAL LIABILITY TO CLIENTS WHO ARE DISSATISFIED WITH OUR SERVICES.

    We design, develop, implement and manage Internet and electronic commerce
solutions that are crucial to the operation of our clients' businesses. Defects
in the solutions we develop could result in delayed or lost revenues, adverse
customer reaction and negative publicity about us or our services or require
expensive corrections, any of which could have a material adverse effect on our
business, financial condition or results of operations. Clients who are not
satisfied with our services could bring claims against us for substantial
damages. Any claims asserted against us could exceed the level of our insurance.
We cannot assure you that the insurance we carry will continue to be available
on economically reasonable terms, or at all. The successful assertion of one or
more large claims against us that are uninsured, exceed our insurance coverage
or result in changes to our insurance policies, including premium increases,
could have a material adverse effect on our business, financial condition or
results of operations.

OUR FAILURE TO PROTECT OUR INTELLECTUAL PROPERTY RIGHTS OR MAINTAIN OUR RIGHTS
  TO USE LICENSED INTELLECTUAL PROPERTY COULD ADVERSELY AFFECT OUR BUSINESS.

    We believe our success depends, in part, on protecting our proprietary
intellectual property. We have not received patent or copyright protection for
most of our intellectual property. We cannot assure you that we will be able to
prevent infringement or detect misappropriation of our intellectual property. A
failure to protect our intellectual property in a meaningful manner could have a
material adverse effect on our business, financial condition and results of
operations.

    We rely on technologies licensed from third parties. We cannot assure you
that these licenses will continue to be available to us on commercially
reasonable terms. The loss of these technologies could require us to obtain
substitute technologies of lower quality or performance standards or at greater
cost, which could have a material adverse effect on our business, financial
condition or results of operations.

    Third parties may assert or prosecute infringement claims against us in
connection with the services and products we offer, and we may or may not be
able to successfully defend any such claims. We generally indemnify our clients
against any third-party intellectual property claims. Any significant claim
against us or for which we have indemnified others could have a material adverse
effect on our business, financial condition and results of operations.

                                       8
<PAGE>
    In connection with our Internet and electronic commerce professional
services, we develop intellectual property for our clients. We frequently assign
ownership of such intellectual property to the client and retain only a license
for limited uses. Issues relating to ownership of and rights to use intellectual
property can be complicated. We may become involved in disputes that affect our
ability to resell or reuse this intellectual property. In addition, many of our
projects involve the use of material that is confidential or proprietary client
information. The successful assertion of one or more large claims against us by
our clients or other third parties could adversely affect us.

WE SOMETIMES AGREE NOT TO PERFORM SERVICES FOR OUR CLIENTS' COMPETITORS.

    Our customer contracts may contain restrictive provisions which are in
effect during the term of the contract and may remain in effect for a limited
period, generally one year, thereafter. The scope of the restrictive provisions
varies and can include provisions restricting our employees who are engaged on a
project for a client from performing the same or substantially similar services
for a competitor of that client and provisions prohibiting us from developing
products or performing services for our clients' competitors. These restrictive
provisions may limit our ability to enter into engagements with new clients for
specified periods of time.

OUR INTERNATIONAL OPERATIONS AND EXPANSION INVOLVE FINANCIAL AND OPERATIONAL
  RISKS.

    We intend to expand our business into international markets. Revenues from
our existing international operations were insignificant in 1998. We may incur
significant costs in connection with our international expansion.

    There are also risks inherent in doing business in foreign countries, such
as:

    - changes in legal and regulatory requirements;

    - export and import restrictions, tariffs and other trade barriers;

    - currency fluctuations and the on-going conversion to the euro in several
      member states of the European Union;

    - difficulties in staffing and managing foreign offices as a result of,
      among other things, distance, language and cultural differences;

    - longer payment cycles and problems in collecting accounts receivable;

    - political and economic instability;

    - seasonal reductions in business activity; and

    - potentially adverse tax consequences.

    Any of these factors could have a material adverse effect on our
international and domestic business, financial condition and results of
operations.

OUR ELECTRONIC COMMERCE OUTSOURCING CENTERS COULD BE VULNERABLE TO SECURITY AND
  TECHNICAL RISKS AND MAY REQUIRE ADDITIONAL INVESTMENT.

    We provide electronic commerce outsourcing services to our customers. We
perform electronic commerce functions that would otherwise be handled by the
customer's internal staff using the customer's resources.

    Our electronic commerce outsourcing services rely on encryption and
authentication technology licenses from third parties to provide the security
and authentication needed to safely transmit confidential information. Although
we have designed and implemented a variety of network security measures,
unauthorized access, computer viruses, accidental or intentional acts and other
disruptions

                                       9
<PAGE>
may occur. Our electronic commerce outsourcing centers may experience delays or
service interruptions as a result of the accidental or intentional acts of
Internet users, current and former employees or others. Such acts could
potentially jeopardize the security of confidential information, such as credit
card and bank account numbers, stored in our and our clients' computer systems.
Such a breach in security could result in liability to us and in the loss of
existing clients or the deterrence of potential clients.

    Although we plan to continue using industry-standard security measures, such
measures have been circumvented in the past, and ours may be circumvented in the
future. The costs required to eliminate computer viruses and alleviate other
security problems could be prohibitively expensive, and efforts to address such
problems could result in delays or interruption of service to our clients. These
could in turn have a material adverse effect on our business, financial
condition and results of operations.

    In the event our hardware malfunctions and our back-up systems fail, we may
not be able to maintain our standard of service to our customers. In addition,
each of our electronic commerce outsourcing centers has been configured to
provide services that facilitate commerce and communication either between
businesses and consumers, known as business-to-consumer services, or between
businesses and their trading partners, known as business-to-business services,
but not both. If we were unable to provide outsourcing services at one of our
outsourcing centers, it would materially adversely impact our ability to
continue to provide the type of electronic commerce outsourcing services
processed through that center. We may be required to make additional investments
in our electronic commerce outsourcing centers in order to increase capacity and
respond to technological developments.

OUR INTANGIBLE ASSETS REPRESENT A SIGNIFICANT PORTION OF OUR ASSETS;
  AMORTIZATION OF OUR INTANGIBLE ASSETS WILL ADVERSELY IMPACT OUR NET INCOME AND
  WE MAY NEVER REALIZE THE FULL VALUE OF OUR INTANGIBLE ASSETS.


    Our acquisitions have resulted in significant goodwill and other intangible
assets, which are being amortized over various periods, primarily two to three
years. At March 31, 1999, we had goodwill and other intangible assets of
approximately $133.1 million, net of accumulated amortization. Charges we would
have incurred in connection with the amortization of intangible assets during
the year ended December 31, 1998 and the three months ended March 31, 1999,
after giving pro forma effect to the acquisitions we made in 1998 and 1999,
would have decreased our net income by $49.1 million and $0.1 million,
respectively. The amount of goodwill associated with the acquisitions we made in
1998 and 1999 may increase in the future as a result of a portion of the
contingent purchase consideration that may become payable if the agreed-upon
operating targets for the following four acquired companies are fully met: LOGEX
International, L.L.C., New Media Publishing, Internet Outfitters and TransForm
IT. The actual amount of goodwill that will be recorded will depend in part on
the price per share of our common stock and such goodwill will be recorded
through the end of the year 2000. We will continue to incur non-cash charges in
connection with the amortization of our intangible assets over their respective
useful lives, and we expect such charges will have a significant adverse impact
on our net income for the foreseeable future.


    We cannot assure you that we will ever realize the value of these intangible
assets. In the future, as events or changes in circumstances indicate that the
carrying amount of our intangible assets may not be recoverable, we will
evaluate the carrying value of our intangible assets and may take an additional
charge to our earnings. Any future determination requiring the write-off of a
significant portion of unamortized intangible assets could have a material
adverse effect on our business, financial condition or results of operations.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations" for a further discussion of our intangible assets.

THE YEAR 2000 PROBLEM MAY ADVERSELY AFFECT OUR BUSINESS.

    The risks posed by the Year 2000 problem could adversely affect our business
in a number of significant ways. Many of our clients and potential clients
maintain their operations on systems that could be impacted by Year 2000
problems. If our clients fail to ensure their systems are Year 2000 compliant
and Year 2000 problems materially adversely affect them, our business could be
materially adversely affected, particularly if demand for our services declines
while companies redirect their resources to upgrade their computer systems. We
also depend heavily on the availability of the Internet infrastructure to
conduct our business and provide services to our clients. Disruptions in the
Internet infrastructure arising from Year 2000 problems could materially affect
our business, financial condition and results of operations.

    In addition, our business could be materially adversely affected if we
cannot obtain products, services or systems that are Year 2000 compliant when we
need them. We rely on our suppliers for hardware, software and services. We are
in the process of obtaining assurances from our suppliers that they are Year
2000 compliant. Our internal information systems may experience operations
difficulties because of undetected errors or defects in the technology used. The
expense to correct such defects could have a material adverse effect on our
business, results of operations and financial condition.

    Because we provide computer-related services, the risk we will be involved
in a lawsuit relating to Year 2000 issues is likely to be greater than that of
companies in other industries. Because the solutions we deliver are sometimes
dependent upon third-party products and components, it may be difficult to
determine which component of our solution may cause a Year 2000 problem. As a
result, we may become involved in litigation concerning our services or products
and components of a third party. We sometimes provide an express warranty to
clients that our work is Year 2000 compliant. However, even absent an express
Year 2000 warranty, there is a risk that clients for whom we have provided
services will try to hold us liable for damages caused by the Year 2000 problem.

    We cannot guarantee that we will be Year 2000 compliant in a timely manner.
Moreover, the costs related to Year 2000 compliance could be significant. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" for a further discussion of the potential effects of the Year 2000
problem on our business.

GOVERNMENT REGULATION AND LEGAL UNCERTAINTIES RELATING TO THE INTERNET COULD
  ADVERSELY AFFECT OUR BUSINESS.

    Increased regulation of the Internet might slow the growth in use of the
Internet, which could decrease demand for our services, increase our cost of
doing business or otherwise have a material adverse effect on our business,
financial condition and results of operations. Congress has recently passed
legislation regulating certain aspects of the Internet, including on-line
content, children's protection, copyright infringement, user privacy, taxation,
access charges, liability for third-party activities, transmission of sexually
explicit material and jurisdiction. In addition, federal, state and local
governmental organizations as well as foreign governments are considering other
legislative and regulatory proposals that would regulate the Internet. Areas of
potential regulation include libel, pricing, quality of products and services
and intellectual property ownership. We do not know how courts will interpret
laws governing the Internet or the extent to which they will apply existing laws
regulating issues such as property ownership, libel and personal privacy to the
Internet. Therefore, we are not certain how new laws governing the Internet or
other existing laws will affect our business.

APPNET IS CONTROLLED BY ITS SIGNIFICANT STOCKHOLDERS.


    Upon completion of this offering, Ken Bajaj, AppNet's President and Chief
Executive Officer, and GTCR will beneficially own 9.8% and 43.6%, respectively,
of our outstanding common stock. As a result, GTCR and Mr. Bajaj will be able to
exercise a controlling influence over the outcome of matters


                                       11
<PAGE>

submitted to our stockholders for approval, including the election of directors,
appointment of new management, amendments to our certificate of incorporation
and mergers or sales of all of our assets. GTCR and Mr. Bajaj will have the
power to delay, defer or prevent a change in control of AppNet. See
"Management--Board of Directors," "Principal Stockholders" and "Certain
Relationships and Transactions" for a further discussion of Mr. Bajaj's and
GTCR's ownership of our capital stock and their respective relationships with
us.


INVESTORS IN THIS OFFERING WILL EXPERIENCE IMMEDIATE AND SUBSTANTIAL DILUTION.


    If you purchase common stock in this offering, you will pay more for your
shares than the amounts paid by existing stockholders for their shares. As a
result you will experience immediate and substantial dilution of approximately
$13.05, representing the difference between our net tangible book value per
share as of March 31, 1999, after giving pro forma effect to this offering, and
the acquisitions we made in 1999, and the assumed initial public offering price
of $13.00 per share. In addition, you may experience further dilution to the
extent that shares of our common stock are issued upon the exercise of stock
options and warrants, the conversion of promissory notes and the achievement of
targets for contingent payment consideration paid in connection with four of the
following acquisitions: New Media Publishing, Sigma6, Salzinger & Company and
Internet Outfitters. These shares generally will be issued at a purchase price
less than the public offering price per share in this offering. See "Dilution"
for a more complete description of how the value of your investment in our
common stock will be diluted upon the completion of this offering.


EXTERNAL FACTORS COULD ADVERSELY AFFECT THE MARKET PRICE OF OUR COMMON STOCK.

    There is currently no public market for our common stock, and we cannot
assure you that an active trading market will develop or be sustained after this
offering. The initial public offering price will be determined through
negotiation between us and representatives of the underwriters and may not be
indicative of the market price for the common stock after this offering.

    The market price of our common stock could fluctuate significantly as a
result of:

    - variations in our operating results which may cause us to fail to meet
      analysts' or investors' expectations;

    - general economic and stock market conditions;

    - changes in financial estimates by securities analysts;

    - earnings and other announcements by, and changes in market evaluations of,
      providers of Internet and electronic commerce professional services;

    - changes in business or regulatory conditions affecting us;

    - announcements by us or our competitors of technological innovations or new
      products or services; and

    - trading of our common stock.

    The securities of many companies have experienced extreme price and volume
fluctuations in recent years, often unrelated to the companies' operating
performance. For example, market prices for securities of Internet-related and
technology companies have frequently reached elevated levels, often following
these companies' initial public offerings. These levels may not be sustainable
and may not bear any relationship to these companies' operating performances. If
the market price of our common stock reaches an elevated level following this
offering, it is likely to materially decline. In the past, following periods of
volatility in the market price of a company's securities, that company's
stockholders have often instituted securities class action litigation against
the company. If we were involved in such a

                                       12
<PAGE>
class action suit, it could have a material adverse effect on our business,
financial condition and results of operations.

THE SALE OR AVAILABILITY FOR SALE OF SUBSTANTIAL AMOUNTS OF OUR COMMON STOCK
  COULD ADVERSELY AFFECT ITS MARKET PRICE.

    Sales of substantial amounts of our common stock in the public market after
the completion of this offering, or the perception that such sales could occur,
could adversely affect the market price of our common stock and could materially
impair our future ability to raise capital through offerings of our common
stock.

    In connection with this offering, we, our officers, our directors, most of
the former owners of all of the businesses we acquired, GTCR and Smart
Technology have agreed not to offer or transfer any shares of common stock for
180 days after completion of this offering without the underwriters' consent;
however, the underwriters may release these shares from these restrictions at
any time. We cannot predict what effect, if any, market sales of shares held by
GTCR or any other shareholder or the availability of these shares for future
sale will have on the market price of our common stock. See "Shares Eligible for
Future Sale" for a more detailed description of the restrictions on selling
shares of our common stock after this offering.

ANTI-TAKEOVER PROVISIONS OF DELAWARE'S GENERAL CORPORATION LAW AND OUR
  CERTIFICATE OF INCORPORATION COULD DELAY OR DETER A CHANGE IN CONTROL.


    Amendments we intend to make to our amended and restated certificate of
incorporation and our bylaws, as well as various provisions of the Delaware
General Corporation Law, may make it more difficult to effect a change in
control of our company. The existence of these provisions may adversely affect
the price of our common stock, discourage third parties from making a bid for
our company or reduce any premiums paid to our stockholders for their common
stock. For example, we intend to amend our certificate of incorporation to
authorize our Board of Directors to issue up to 4,883,379 shares of "blank
check" preferred stock and to attach special rights and preferences to such
preferred stock. The issuance of this preferred stock may make it more difficult
for a third party to acquire control of us. See "Description of Capital
Stock--Preferred stock," and "Description of Capital Stock-- Anti-takeover
effects of AppNet's certificate of incorporation and bylaws and provisions of
Delaware law" for a more complete description of our capital stock, our
Certificate of Incorporation and the effects of the Delaware General Corporation
Law which could hinder a third party's attempts to acquire control of us.


                               CAUTIONARY NOTICE
                      REGARDING FORWARD-LOOKING STATEMENTS

    This prospectus includes "forward-looking statements" for purposes of the
Securities Act of 1933 and the Securities Exchange Act of 1934. All statements
other than statements of historical fact in this prospectus, including
statements regarding our competitive strengths, business strategy, expected
benefits of any acquisition, future financial position, budgets, projected costs
and plans and objectives of management are forward-looking statements. In
addition, forward-looking statements generally can be identified by the use of
forward-looking terminology such as "may," "will," "expect," "should," "intend,"
"estimate," "anticipate," "believe," "continue" or similar terminology. Although
we believe that the expectations reflected in any forward-looking statements are
reasonable, we can give no assurance that these expectations will prove to have
been correct. Important factors that could cause actual results to differ
materially from our expectations are disclosed under "Risk Factors" and
elsewhere in this prospectus and expressly qualify all written and oral
forward-looking statements attributable to us. We undertake no obligation to
update publicly or revise any forward-looking statements.

                                USE OF PROCEEDS

    The net proceeds to AppNet from the sale of the 6,000,000 shares of our
common stock being offered by this prospectus are estimated to be approximately
$69.5 million, or $80.4 million if the underwriters exercise their
over-allotment option in full, based upon an assumed initial public offering
price of $13.00 per share, the mid-point of the range shown on the cover page of
this prospectus, after deducting underwriting discounts and commissions and
estimated offering expenses payable by AppNet.

    We expect to use the net proceeds from this offering to:

    - repay approximately $61.7 million of aggregate indebtedness, including
      accrued interest under our existing credit facilities, a $26 million
      revolving credit facility and a $40 million revolving credit facility,
      both of which are with BankBoston, N.A. and Antares Capital Corporation;

    - redeem 1,641 shares of Class A Preferred Stock at an aggregate redemption
      price of $1.7 million, including related accrued dividends;

    - redeem 418 shares of Class B Preferred Stock at an aggregate redemption
      price of $0.4 million, including related accrued dividends;

    - repay $3,300 on a note to Smart Technology, L.L.C., which bears interest
      at a rate of 12% per annum, is due upon consummation of this offering and
      evidences indebtness incurred to fund general working capital purposes;

    - repay $16,000 in interest on a note to Fairfax Management Company II,
      L.L.C., which bears interest at a rate of 5% per annum, the principal
      amount of which will be converted into our common stock upon consummation
      of this offering and evidences indebtedness incurred to repurchase shares
      of our common stock; and

    - fund general corporate purposes, including working capital requirements.

    To the extent we receive additional proceeds from this offering, we will use
them to fund general corporate purposes and to redeem additional shares of our
Class A and Class B Preferred Stock on a pro rata basis. As additional shares of
Class A and Class B Preferred Stock are redeemed, the number of shares of Class
A and Class B Preferred Stock that we will exchange into shares of our common
stock will be reduced accordingly.


    The amounts borrowed under our existing credit facilities are due in full on
August 24, 2001. The interest rate on indebtedness under the $26 million
revolving credit facility is variable and ranges from the prime rate plus 0.25%
to the prime rate plus 1.5% or from LIBOR plus 2.25% to LIBOR plus 3.5%. The $40
million revolving credit facility carries interest at the prime rate plus 0.5%
or LIBOR plus 2.5%. We intend to terminate the $40 million revolving credit
facility following the consummation of this offering and amend the $26 million
revolving credit facility to provide for maximum aggregate revolving borrowings
of up to $20 million. We will use amounts which may be reborrowed under the $20
million revolving credit facility following the consummation of this offering
for working capital and general corporate purposes, including acquisitions. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and capital resources" for a discussion of our future
liquidity.


    We anticipate that, in addition to the underwriting discounts and
commissions, we will pay fees and expenses of approximately $3.0 million in
connection with this offering. The principal components of that amount will be
the fees and expenses of our accountants and attorneys, the costs of printing
this prospectus and other offering materials, The Nasdaq Stock Market listing
fees and Securities and Exchange Commission and National Association of
Securities Dealers filing fees.

                                DIVIDEND POLICY

    We have never declared or paid any cash dividends on our common stock and do
not expect to do so in the foreseeable future. The terms of our Class A and
Class B Preferred Stock and of our credit facilities restrict our ability to pay
dividends on our common stock. We intend to retain any earnings to finance the
expansion and development of our business. Subject to the restriction on
dividends in our credit facilities, any future determination to pay dividends
will be made at the discretion of our Board of Directors and will be based upon
our earnings, financial condition and capital requirements and any other
conditions our Board of Directors deems relevant.

                                 CAPITALIZATION

    The following table sets forth AppNet's capitalization as of March 31, 1999
on an actual basis and on a pro forma as adjusted basis to reflect:

    - the sale of 6,000,000 shares of common stock in this offering at an
      assumed initial public offering price of $13.00 per share, the mid-point
      of the range shown on the cover page of this prospectus, net of $8.5
      million of offering expenses, and the application of the net proceeds of
      this offering;

    - the conversion of a promissory note for approximately $406,000 to Fairfax
      Management Company II, L.L.C. into shares of common stock at 80% of the
      initial public offering price in this offering;


    - the conversion of promissory notes for approximately $1.0 million plus
      accrued interest to former owners of Century Computing, Incorporated into
      123,210 shares of common stock at a conversion price of $8.55 per share;


    - the exchange of 43,789 shares of Class A Preferred Stock and 11,158 shares
      of Class B Preferred Stock, including related accrued dividends, for
      4,334,281 shares of common stock at an exchange rate based on an assumed
      initial public offering price of $13.00 per share, the mid-point of the
      range shown on the cover page of this prospectus;

    - a compensation charge of approximately $2.7 million that we would have
      incurred at March 31, 1999 upon consummation of this offering in
      connection with the termination of our right to repurchase 210,119 shares
      of our common stock from Mr. Bajaj at a per share price of $0.3007; and

    - an interest charge of approximately $0.9 million related to beneficial
      conversion rights of convertible notes.

    You should read this table in conjunction with "Use of Proceeds," "Pro Forma
Consolidated Financial Data," "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and our consolidated financial statements

(a) Other long-term debt includes current and non-current debt obligations and
    capital lease obligations.

(b) Class A Preferred Stock is recorded at its liquidation value, net of
    issuance costs. Excludes, as of March 31, 1999, 121 shares of Class A
    Preferred Stock reserved for issuance at an exercise price equal to the
    liquidation value per share in connection with an outstanding warrant to
    purchase Class A Preferred Stock.

(c) The holders of these shares of common stock had the right to require AppNet
    to repurchase the shares for an aggregate purchase price of approximately
    $278,000. This right terminated on April 11, 1999.

                                    DILUTION


    AppNet's pro forma net tangible book value as of March 31, 1999 was a
deficit of $70.9 million or $(2.91) per share of common stock. Pro forma net
tangible book value per share of common stock represents the amount of total
tangible assets less the sum of (a) total liabilities and (b) the liquidation
preference of the Class A Preferred Stock and the Class B Preferred Stock and
the repurchase price of common stock subject to put rights and increased by the
effect of the conversion of the $406,000 promissory note into 39,055 shares of
common stock, the conversion of promissory notes of $1,012,000, plus accrued
interest, into 123,210 shares of common stock and the exchange of 43,789 and
11,158 shares of Class A and Class B Preferred Stock, plus related accrued
dividends, respectively into 4,334,281 shares of common stock, divided by the
number of shares of common stock outstanding. After giving effect to the sale of
6,000,000 shares of our common stock in this offering at an assumed initial
public offering price of $13.00 per share, the mid-point of the range shown on
the cover page of this prospectus, and the application of the estimated net
proceeds from this offering, AppNet's adjusted pro forma net tangible book value
at March 31, 1999 would have been a deficit of approximately $1.4 million or
$(0.05) per share of common stock. This represents an immediate increase in pro
forma net tangible book value of $2.86 per share of common stock to existing
stockholders and an immediate dilution in pro forma net tangible book value of
$13.05 per share of common stock to new investors purchasing shares in this
offering. Dilution is determined by subtracting pro forma net tangible book
value per share after the offering from the amount of cash paid by a new
investor for a share of common stock. The following table illustrates this per
share dilution as of March 31, 1999:

</TABLE>



    As of March 31, 1999, there were outstanding options to purchase 1,563,891
shares of common stock at a weighted average exercise price of $10.72 per share,
outstanding warrants to purchase 84,795 shares of common stock at a weighted
average exercise price of $0.3007 per share, and convertible notes, excluding
the convertible notes reflected above, to purchase 887,473 shares of common
stock at a weighted average exercise price of $11.03 per share. In addition,
$5.2 million of notes payable are convertible at 80% of the initial public
offering price. To the extent that these options and warrants are exercised, and
the convertible notes are converted, there will be further dilution to new
investors. New investors could also experience further dilution as a result of
the issuance of shares of common stock to the former owners of four of the
businesses we have acquired in connection with contingent payments payable to
them. These acquired businesses are New Media Publishing, Sigma6, Salzinger &
Company and Internet Outfitters.



    The following table sets forth, as of March 31, 1999, the number of shares
of our common stock purchased from AppNet, the total consideration paid to
AppNet and the average price paid per share by existing stockholders and by new
investors at an assumed initial public offering price of $13.00 per share, the
mid-point of the range shown on the cover page of this prospectus.

    After the 1999 reverse common stock split discussed in Note 18 to AppNet
Systems, Inc.'s consolidated financial statements is effected, we expect to be
in a position to render the following report.

                                          /s/ ARTHUR ANDERSEN LLP

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To AppNet Systems, Inc.:


    We have examined the pro forma and offering adjustments reflecting the
transactions described in the introduction to the pro forma consolidated
financial data contained on page 20 and in Notes (a) through (j) to this
statement and the application of those adjustments to the historical amounts in
the accompanying pro forma consolidated statement of operations of AppNet
Systems, Inc. for the year ended December 31, 1998. The historical consolidated
statement of operations is derived from the year ended December 31, 1998
historical financial statements of AppNet Systems, Inc., i33 communications
corp., Salzinger & Company, Inc. and Internet Outfitters, Inc., each of which
were audited by us, appearing elsewhere herein, the financial statements of
Arbor Intelligent Systems, Inc., Software Services Corporation, New Media
Publishing, Inc., Century Computing, Incorporated, Research & Planning, Inc. and
The Kodiak Group, Inc. acquired by AppNet Systems, Inc. during 1998 for the
period in 1998 prior to their acquisitions, each of which were also audited by
us, appearing elsewhere herein, the unaudited historical financial statements of
Logex International, L.L.C. for the period in 1998 prior to its acquisition and
the unaudited historical financial statements of Sigma6, Inc., and Transform IT,
Incorporated for the year ended December 31, 1998. Such pro forma and offering
adjustments are based upon management's assumptions described in the
introduction to the pro forma consolidated financial data contained on page 20
and in Notes (a) through (j). Our examination was made in accordance with
standards established by the American Institute of Certified Public Accountants
and, accordingly, included such procedures as we considered necessary in the
circumstances.



    In addition, we have reviewed the related pro forma and offering adjustments
reflecting the transactions described in the introduction to the pro forma
consolidated financial data contained on page 20 and in Notes (a) through (j)
and the application of those adjustments to the historical amounts in the
accompanying pro forma consolidated statement of operations for the three months
ended March 31, 1999. The historical consolidated statement of operations is
derived from the historical unaudited statement of operations of AppNet Systems,
Inc., which was reviewed by us, appearing elsewhere herein, and the historical
unaudited statements of operations for i33 communications corp., Salzinger &
Company, Inc., Internet Outfitters, Inc., Sigma6, Inc. and Transform IT,
Incorporated for the period in 1999 prior to their acquisitions, each of which
were reviewed by us. Such pro forma and offering adjustments are based on
management's assumptions as described in the introduction to the pro forma
consolidated financial data contained on page 20 and in Notes (a) through (j).
Our review was made in accordance with standards established by the American
Institute of Certified Public Accountants.


    The objective of this pro forma financial information is to show what the
significant effects on the historical financial information might have been had
the transactions occurred at an earlier date. However, the pro forma
consolidated statements of operations are not necessarily indicative of the
results of operations that would have been attained had the above-mentioned
transactions actually occurred earlier.

                                       18
<PAGE>

    In our opinion, management's assumptions provide a reasonable basis for
presenting the significant effects directly attributable to the above-mentioned
transactions described in the introduction to the pro forma consolidated
financial data contained on page 20 and in Notes (a) through (j), the related
pro forma and offering adjustments give appropriate effect to those assumptions,
and the pro forma as adjusted columns reflect the proper application of those
adjustments to the historical financial amounts in the pro forma consolidated
statement of operations for the year ended December 31, 1998.



    A review is substantially less in scope than an examination, the objective
of which is the expression of an opinion on management's assumptions, the pro
forma and offering adjustments and the application of those adjustments to
historical financial information. Accordingly, we do not express such an opinion
on the pro forma and offering adjustments or the application of such adjustments
to the pro forma consolidated statement of operations for the three months ended
March 31, 1999. Based on our review, however, nothing came to our attention that
caused us to believe that management's assumptions do not provide a reasonable
basis for presenting the significant effects directly attributable to the
above-mentioned transaction described in the introduction to the pro forma
consolidated financial data contained on page 20 and in Notes (a) through (j),
that the related pro forma and offering adjustments do not give appropriate
effect to those assumptions, or that the pro forma as adjusted column does not
reflect the proper application of those adjustments to the historical financial
statement amounts in the pro forma consolidated statement of operations for the
three months ended March 31, 1999.

                     PRO FORMA CONSOLIDATED FINANCIAL DATA

    The following tables set forth the unaudited pro forma consolidated
statements of operations of AppNet for the year ended December 31, 1998 and for
the three months ended March 31, 1999. The pro forma consolidated statements of
operations for the year ended December 31, 1998 give effect (1) on a pro forma
basis, to the acquisitions we made in 1998 and 1999 and GTCR's investment in
AppNet, as if these transactions had occurred on January 1, 1998 and (2) on a
pro forma, as adjusted, basis to reflect:

    - the reduction of interest expense due to the conversion of a $406,000 note
      payable which automatically converts into shares of our common stock upon
      the offering;


    - the reduction of interest expense due to the conversion of promissory
      notes of approximately $1.0 million plus accrued interest into 123,210
      shares of common stock;


    - the reduction of the dividends on and accretion of preferred stock
      resulting from the exchange of 43,789 and 11,158 shares of Class A and
      Class B Preferred Stock, respectively, plus related accrued dividends, for
      shares of common stock; and

    - the reduction of interest expense and dividends on and accretion of
      preferred stock resulting from the repayment of the credit facilities and
      the redemption of shares of Class A and Class B Preferred Stock in
      connection with the offering, as if such transactions had occurred on
      January 1, 1998.

    The pro forma consolidated statements of operations for the three months
ended March 31, 1999, give effect (1) on a pro forma basis, to the acquisitions
we made in 1998 and 1999, as if these acquisitions had occurred on January 1,
1998 and (2) on a pro forma, as adjusted, basis to reflect:

    - the reduction of interest expense due to the conversion of a $406,000 note
      payable which automatically converts into shares of our common stock upon
      the offering;


    - the reduction of interest expense due to the conversion of promissory
      notes of approximately $1.0 million plus accrued interest into 123,210
      shares of common stock;


    - the reduction of the dividends on and accretion of preferred stock
      resulting from the exchange of 43,789 and 11,158 shares of Class A and
      Class B Preferred Stock, respectively, plus related accrued dividends, for
      shares of common stock; and

    - the reduction of interest expense and dividends on and accretion of
      preferred stock resulting from the repayment of the credit facilities and
      the redemption of shares of Class A and Class B Preferred Stock in
      connection with the offering, as if such transactions had occurred on
      January 1, 1998.

    The information in the pro forma consolidated statement of operations for
the year ended December 31, 1998 has been derived from the audited statements of
operations for the year ended December 31, 1998 of AppNet, i33 communications
corp., Salzinger & Company, Inc. and Internet Outfitters, Inc., the unaudited
statements of operations of Sigma6, Inc. and TransForm IT, Incorporated for the
year ended December 31, 1998 and the audited statements of operations of the
companies we acquired in 1998 for the periods during 1998 prior to acquisition,
all of which, except the statements of operations for Sigma6, Inc. and TransForm
IT, Incorporated, are included elsewhere in this prospectus.

    The information in the pro forma consolidated statement of operations for
the three months ended March 31, 1999 has been derived from the unaudited
statement of operations of AppNet for the three months ended March 31, 1999,
included elsewhere in this prospectus, and the unaudited statements of
operations for the companies acquired in 1999 for the periods during 1999 prior
to their acquisition.

    The acquisitions we made were accounted for using the purchase method of
accounting. The purchase method of accounting allocates the aggregate purchase
price to the assets acquired and liabilities assumed based upon their respective
fair values. The excess of purchase price over the fair

                                       20
<PAGE>
value of tangible and identifiable intangible assets acquired, net of
liabilities assumed, has been reflected as goodwill. AppNet believes that the
preliminary allocations set forth herein are reasonable; however, in some cases
the final allocations will be based upon valuations and other studies that are
not yet complete. As a result, the allocations set forth herein are subject to
revision as additional information becomes available, and such revised
allocations could differ from those set forth herein.

    The unaudited pro forma consolidated statements of operations are based upon
currently available information and assumptions and estimates which management
believes are reasonable. These assumptions and estimates, however, are subject
to change, including, without limitation, adjustments for potential cost savings
or other synergies arising from the acquisitions we made in 1998 and 1999. These
statements are presented for comparative purposes only and do not purport to be
indicative of the actual results of operations that might have occurred or
expected future results. You should read the unaudited consolidated pro forma
financial data in conjunction with our consolidated financial statements and the
related notes and the audited financial statements and the related notes of the
companies we acquired included elsewhere in this prospectus.

            NOTES TO PRO FORMA CONSOLIDATED STATEMENT OF OPERATIONS
                      FOR THE YEAR ENDED DECEMBER 31, 1998
                 AND FOR THE THREE MONTHS ENDED MARCH 31, 1999
                                  (UNAUDITED)
                                 (IN THOUSANDS)

    The following adjustments were applied to AppNet's consolidated statement of
operations and the financial data of the companies we acquired in 1998 and 1999
to arrive at the unaudited pro forma consolidated statement of operations.

    (a) In the pro forma consolidated statement of operations for the year ended
December 1998, these columns reflect the actual results of operations for the
acquisitions we completed in 1998 from January 1, 1998 to the date prior to
which each respective acquisition was consummated and for the companies we
acquired in 1999 for the full year ended December 31, 1998. In the pro forma
consolidated statement of operations for the three months ended March 31, 1999,
these columns reflect the actual results of operations for the acquisitions we
completed in 1999 from January 1, 1999 to the date prior to which each
respective acquisition was consummated as if they had occurred on January 1,
1998.

    (b) This adjustment was made to record a full year of the estimated
compensation charge for contingent payments in connection with our acquisitions
in 1998 and 1999 and to reduce pro forma expense for stock-based and other
acquisition-related compensation expense recorded by the acquired companies
prior to their acquisition by AppNet which arose as a direct result of their
acquisition by AppNet:

</TABLE>

    See Note 16 of AppNet's historical consolidated financial statements
included elsewhere in this prospectus which further explains the amount shown as
contingent payment compensation expense. This pro forma amount has been
calculated assuming the operating targets related to the contingent payments
payable to the former owners of five of the companies we acquired, New Media
Publishing, Sigma6, Salzinger & Company, Internet Outfitters and TransForm IT,
are fully met and a common
stock price per share of $13.00, the mid-point of the range shown on the cover
page of this prospectus. Approximately 75% of the total contingent payments
which have a fair value of approximately $31.6 million based on a per share
price of common stock of $13.00, the mid-point of the range shown on the cover
page of this prospectus, will be reflected as compensation expense over a
weighted average period of 18 months. These charges will be fully recognized by
the end of the year 2000.


    (c) This adjustment was made to record amortization expense related to
acquired identifiable intangible assets and goodwill. Such amounts are being
amortized over the estimated useful life of each asset, primarily two to three
years. Six of the acquisitions, LOGEX International, New Media Publishing,
Sigma6, Salzinger & Company, Internet Outfitters and TransForm IT, provide for
additional purchase consideration, primarily cash and stock, which is payable
upon the attainment of agreed-upon operating targets. A portion of this amount
will be recorded as additional goodwill. If the operating targets are fully met,
the aggregate amount of additional goodwill will be approximately $8.5 million,
assuming a per share price of common stock at the time the contingency is
resolved of $13.00, the mid-point of the range shown on the cover page of this
prospectus. See "Risk Factors--Our intangible assets represent a significant
portion of our assets; amortization of our intangible assets will adversely
impact our net income and we may never realize the full value of our intangible
assets" for additional information on these amortization expenses.

    (d) This adjustment was made to reflect a full year of interest expense on
acquisition debt financing. The increase in the interest expense is a result of
the amounts drawn under the credit facilities to the balance outstanding on
March 31, 1999 of approximately $59.4 million at a weighted average interest
rate of 8.0%. Additionally, the increase results from notes issued to selling
shareholders with a principal balance of approximately $15.6 million at March
31, 1999 which bear a weighted average interest rate of 5.7%. The adjustment is
as follows:

other professionals incurred by the companies we acquired in 1998 and 1999 which
were directly attributable to the sale of those companies to AppNet.

    (g) This adjustment was made to reflect a full year of preferred stock
dividends on the preferred stock issued to finance our acquisitions.

    (h) Pro forma weighted average common shares outstanding for the year ended
December 31, 1998 reflects the effects of shares we issued in connection with
the acquisitions we made in 1998 and 1999 and GTCR's investment in AppNet, as if
all these shares had been issued as of January 1, 1998. Pro forma weighted
average common shares outstanding for the three months ended March 31, 1999
reflects the effects of shares we issued in connection with the acquisitions we
made in 1999 as if all these shares had been issued as of January 1, 1998.


    Pro forma, as adjusted, weighted average shares outstanding for the year
ended December 31, 1998, and for the three months ended March 31, 1999, reflects
the pro forma weighted average shares outstanding for the respective periods
plus (1) the 6,000,000 shares to be issued in connection with this offering, (2)
the conversion of a $406,000 note payable into 39,055 shares of common stock,
(3) the conversion of promissory notes of $1,012,000 into 123,210 shares of
common stock and (4) the issuance of 4,334,281 shares of common stock in
connection with the exchange of Class A and Class B Preferred Stock and related
accrued dividends.

1997, through December 31, 1997, reflect immaterial transactions and, therefore,
these transactions have been included in our 1998 financial statements to
facilitate presentation. From inception through March 11, 1998, our operating
activities primarily consisted of developing a preliminary business plan,
recruiting personnel, engaging in discussions with prospective lenders and
strategic investors, identifying potential acquisition targets and developing
preliminary technical and marketing materials. Our strategic plan identified the
specific professional services which are required to provide clients with
end-to-end solutions. We then identified a group of companies which focused on
providing services in one or more of these professional services areas. After
reviewing and evaluating over 100 companies, we ultimately acquired a set of
companies that we believe fit together strategically and culturally and which,
when integrated with one another, could design, develop, implement and manage
end-to-end solutions. In March 1998, we completed our first acquisition. Since
that time, AppNet has completed 11 additional acquisitions.

    Typically, the consideration we paid to make our acquisitions included cash,
shares of our common stock, promissory notes, promissory notes convertible into
shares of our common stock and, in six of our acquisitions, LOGEX International,
New Media Publishing, Sigma6, Salzinger & Company, Internet Outfitters and
TransForm IT, contingent payments payable in cash and/or shares of our common
stock payable upon the attainment of agreed-upon operating targets. The cash
portion of such consideration was financed primarily by an investment in our
company by GTCR and Smart Technology and borrowings under our credit facilities.
Our acquisitions have been accounted for using the purchase method of
accounting. Accordingly, the purchase price has been allocated, based on
preliminary estimates of fair value, to the tangible assets and liabilities
assumed, and in most cases, with the advice of independent valuation experts, to
the identifiable intangible assets, as of the acquisition dates. Final estimates
of fair value will be made upon the completion of independent valuations for our
1999 acquisitions and the final determination of preexisting contingencies.
Since the Internet and the electronic commerce industries are in an early stage
of development and continue to evolve rapidly and because competition in these
industries is expected to increase, the recorded goodwill and identified
intangibles from each of the acquisitions are being amortized on a straight-line
basis primarily over two to three years, the estimated period of benefit.

                                       28

    AppNet's revenues are comprised primarily of fees generated for professional
services billed. We also generate fees from outsourcing services although these
fees currently represent a small portion of our revenues. Our strategy is to
increase the percentage of our revenues generated by fees from outsourcing
services. During the development of our outsourcing business, we may incur
losses and operating margins may be reduced as we build our operations and
infrastructure to support this line of business.

    In general, we bill our professional services on a time and materials basis;
however, a portion of our services is billed on a fixed-price basis. AppNet
recognizes revenue from time and materials projects based on fixed hourly rates
for direct labor hours expended and revenues from fixed-price projects based on
the percentage-of-completion method of accounting, with costs and estimated
profits recorded as work is performed. Provisions for estimated losses on
uncompleted contracts are made in the period in which the losses are determined.
Changes in contract scope and estimated profitability, including final contract
settlements, may result in adjustments to costs and revenues and are recognized
in the period in which the adjustments are determined.

    AppNet's cost of revenues includes all direct labor and other direct costs
related to contract performance. Cost of revenues consists primarily of salaries
and related employee benefits of billable employees.

    Selling and marketing expenses are comprised of the salaries and related
employee benefits of sales and marketing employees and the costs of sales,
marketing and advertising activities. We compensate our sales employees with a
combination of base salaries and commissions. We anticipate that selling and
marketing expenses may increase as a percentage of our revenues in future
periods as we continue to build our corporate sales team and expand our
marketing strategy.

    AppNet's general and administrative costs include salaries and related
employee benefits for finance, legal, human resources and administrative
personnel. The general and administrative expenses also include facilities
costs, recruiting, training and other corporate costs. As a result of
anticipated additional hiring costs associated with the integration of the
businesses we acquired in 1998 and 1999, our general and administrative expenses
will increase, although they may decline as a percentage of our revenues.

    Stock-based and other acquisition-related compensation includes expenses
related to the cash and stock-based contingent payments payable to former owners
of five businesses, New Media Publishing, Sigma6, Salzinger & Company, Internet
Outfitters and TransForm IT, we acquired if agreed-upon operating targets are
achieved and these former stockholders remain employed by AppNet. These
contingent payments are accounted for as operating expenses in accordance with
Emerging Issues Task Force 95-08, "Accounting for Contingent Consideration Paid
to the Shareholders of an Acquired Company in a Purchase Business Combination,"
instead of as additional purchase consideration at the time of the acquisition
because many of the former owners to whom payments are payable must remain
employed by AppNet in order for them to receive these payments. The amount of
this compensation expense recorded periodically will fluctuate based on the
probability of achievement of the operating targets by each of the acquired
businesses and the market price of our common stock at the end of each reporting
period. This expense is recognized over the period during which these former
stockholders must remain employed by us to be eligible to receive the contingent
payments. The remaining portion of these contingent payments that is payable to
former shareholders who are not our employees or who are not required to remain
employed by us during the contingent payment period will be recorded as
additional goodwill when such targets are met. If all of the operating targets
are fully met, the aggregate amounts of compensation expense and additional
goodwill that will be recognized will be approximately $23.1 and $8.5 million,
respectively, assuming a per share price of common stock of $13.00, the
mid-point of the range shown on the cover page of this prospectus, for all

                                       29
<PAGE>
shares issued in connection with these contingent payments. The compensation
expense will be recognized during 1999 and 2000.

    A compensation charge will be recorded within stock-based and
acquisition-related compensation upon completion of this offering in connection
with the termination of our right to repurchase shares of our common stock from
Mr. Bajaj. The amount of the compensation charge will be determined based on the
number of common shares that we could have repurchased from him and the
difference between $0.3007 and the initial public offering price of our common
stock. This compensation charge would have been approximately $2.7 million if
this offering had occurred on March 31, 1999. Also, we will incur an interest
charge of approximately $0.9 million related to the beneficial conversion of
convertible notes at the time of this offering.

    Operating results may fluctuate from quarter to quarter and from year to
year based on such factors as the number, size, type and profitability of
projects in which we are engaged. Other factors that could cause our quarterly
results to fluctuate include:

    - effectiveness of integrating acquisitions with existing operations;

    - our ability to attract, train and retain skilled management, technical and
      creative personnel;

    - the entrance of new competitors; and

    - timing and size of acquisition-related compensation charges which
      fluctuate based on the market price of our stock and the level of
      achievement of the agreed upon operating targets.

APPNET PRO FORMA RESULTS OF OPERATIONS

    The pro forma statement of operations for the year ended December 31, 1998
gives effect to the 12 acquisitions we made in 1998 and 1999 and GTCR's
investment in AppNet, as if these transactions had occurred on January 1, 1998.
The pro forma statement of operations for the three months ended March 31, 1999
gives effect to the acquisitions we made in 1999 as if these transactions had
occurred on January 1, 1998. Our pro forma quarterly and annual results may not
be indicative of future operations as a result of our continued integration of
acquired companies and the development of our corporate infrastructure.

THREE MONTHS ENDED MARCH 31, 1999

    REVENUES.  Pro forma revenues for the three months ended March 31, 1999 were
$22.3 million.

    COST OF REVENUES.  For the three months ended March 31, 1999, cost of
revenues was $13.1 million, or 59% of pro forma revenues.

    SELLING AND MARKETING.  Pro forma selling and marketing expenses for the
three months ended March 31, 1999 were $1.4 million, or 6% of pro forma
revenues.

    GENERAL AND ADMINISTRATIVE.  Pro forma general and administrative expenses
were $7.4 million, or 33% of pro forma revenues. The increase in general and
administrative expenses as a percentage of revenue from pro forma 1998 fiscal
year activity is a result of the build up of corporate infrastructure through
1998 and into 1999 to assist in the integration of acquisitions.

    STOCK-BASED AND OTHER ACQUISITION-RELATED COMPENSATION.  For the three
months ended March 31, 1999, pro forma stock-based and other acquisition-related
compensation was $2.6 million. The amount is computed based on the assumption
that operating targets will be fully met and that the fair market value of our
common stock is $13.00 per share, the mid-point of the range shown on the cover
page of this prospectus, as if the 1999 acquisitions had occurred on January 1,
1998.

                                       30
<PAGE>
    DEPRECIATION AND AMORTIZATION.  Pro forma depreciation and amortization for
the three months ended March 31, 1999 was $12.8 million, of which $12.3 million
represents amortization of intangible assets.

    INTEREST EXPENSE.  For the three months ended March 31, 1999, pro forma
interest expense was $1.5 million, the majority of which is a result of the
financing of acquisitions. We expect to repay existing borrowings under our
credit facilities with a portion of the proceeds from this offering which, along
with the conversion of a $406,000 note payable into common stock, would have
reduced interest expense on a pro forma as adjusted basis to $0.2 million.

YEAR ENDED DECEMBER 31, 1998

    REVENUES.  Pro forma revenues for the year ended December 31, 1998 were
$69.2 million. This amount consists primarily of revenues from fees for
professional services. We also generated revenues from fees for outsourcing
services; the amount of these fees represented a small portion of our revenues
for this period.

    COST OF REVENUES.  For the year ended December 31, 1998, pro forma cost of
revenues was $41.9 million, or 61% of revenues.

    SELLING AND MARKETING.  Pro forma selling and marketing expenses were $3.3
million for the year ended December 31, 1998, or 5% of revenues.

    GENERAL AND ADMINISTRATIVE.  For the year ended December 31, 1998, pro forma
general and administrative expenses were $19.0 million, or 28% of revenues.

    STOCK-BASED AND OTHER ACQUISITION-RELATED COMPENSATION.  Pro forma
stock-based and other acquisition-related compensation for the year ended
December 31, 1998 was $16.8 million. This amount represents an accrual for the
estimated amount of the cash and stock-based contingent consideration to be paid
to former owners of five of our acquired businesses, New Media Publishing,
Sigma6, Salzinger & Company, Internet Outfitters and TransForm IT, during the
12-month period following acquisition. The amount is based on assumptions that
operating targets will be fully met and that the fair market value of our common
stock is $13.00 per share, the mid-point of the range shown on the cover page of
this prospectus.


    DEPRECIATION AND AMORTIZATION.  For the year ended December 31, 1998, pro
forma depreciation and amortization was approximately $60.3 million, the
majority of which represents amortization expense of our intangible assets.


    INTEREST EXPENSE.  Pro forma interest expense for the year ended December
31, 1998 was $5.9 million, or 9% of revenues. This includes interest on
indebtedness borrowed under our credit facilities in connection with our
acquisitions of approximately $4.6 million and interest on notes issued in
connection with these acquisitions of approximately $1.0 million. We expect to
repay existing borrowings under our credit facilities with a portion of the
proceeds of this offering which, along with the conversion of a $406,000 note
payable into common stock, would have reduced interest expense on a pro forma as
adjusted basis to $1.0 million.

    OTHER EXPENSE, NET.  For the year ended December 31, 1998, pro forma other
expense includes a charge of $0.3 million related to the refinancing of our
credit facilities during 1998 and the write-off of approximately $0.3 million
related to an investment in a joint venture that was deemed to have no value due
to the failure of the venture to generate a customer base and to generate
sufficient revenues to cover operating expenses, which resulted in the
abandonment of the operations of the venture.

                                       31
<PAGE>
    INCOME TAXES.  Pro forma income tax benefit for the year ended December 31,
1998 was $0.1 million. The effective income tax rate of 0.1% was lower than the
blended federal and statutory rate primarily as a result of amortization of a
portion of our intangible assets which are not deductible for income tax
purposes and the recognition of a valuation allowance in accordance with
generally accepted accounting principles.

APPNET HISTORICAL RESULTS OF OPERATIONS

    AppNet's first quarter 1999 historical results of operations may not be
indicative of results to be expected for the full year in 1999 due to the impact
of acquisitions during the first quarter of 1999 and the continued integration
of our 1998 acquisitions.

THREE MONTHS ENDED MARCH 31, 1999 COMPARED TO THREE MONTHS ENDED MARCH 31, 1998

    REVENUES.  Revenues for the three months ended March 31, 1999 and 1998 were
$19.6 million and $0.2 million, respectively. The increase of $19.4 million is a
result of the acquisitions that occurred during 1998 and 1999.

    COST OF REVENUES.  For the three months ended March 31, 1999, cost of
revenues were $11.5 million as compared to the cost of revenues for the three
months ended March 31, 1998 of $0.1 million. The increase of $11.4 million was
primarily driven by an increase in average billable headcount resulting from the
acquisitions that occurred during 1998 and 1999.

    SELLING AND MARKETING.  Selling and marketing expenses for the three months
ended March 31, 1999 were $1.2 million. The increase is a result of the
acquisitions we completed and the development of our corporate sales and
marketing staff.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses were $6.8
million and $0.2 million for the three months ended March 31, 1999 and 1998,
respectively. The increase is primarily a result of the acquisitions that
occurred during 1998 and 1999 and the development of our corporate general and
administrative staff.

    STOCK-BASED AND OTHER ACQUISITION-RELATED COMPENSATION.  For the three
months ended March 31, 1999, stock-based and other acquisition-related
compensation was $2.5 million. The amount is primarily attributable to the
contingent payments due to former shareholders that must remain employed to
receive the contingent payments. The amount is computed based on the fair market
value of our common stock at the end of the reporting period and the assumptions
that operating targets will be fully met.

    DEPRECIATION AND AMORTIZATION.  For the three months ended March 31, 1999,
depreciation and amortization was $12.7 million as compared with $0.1 million
for the three months ended March 31, 1998. The increase is primarily due to the
amortization of intangible assets resulting from the acquisitions made during
1998 and 1999. AppNet's goodwill and related amortization may increase in future
periods if AppNet is required to pay additional consideration for its
acquisitions.

    INTEREST EXPENSE.  Interest expense for the three months ended March 31,
1999 was $1.3 million that primarily resulted from the interest on the
outstanding balance on the credit facility entered into in August 1998.

YEAR ENDED DECEMBER 31, 1998 COMPARED TO SOFTWARE SERVICES CORPORATION
  (PREDECESSOR) FOR THE YEAR ENDED DECEMBER 31, 1997

    REVENUES.  Revenues for the year ended December 31, 1998 were $17.7 million
as compared with revenues of $13.3 million of Software Services Corporation for
the year ended December 31, 1997. The

                                       32
<PAGE>
difference of $4.4 million is a result of the acquisitions by AppNet during
1998, as well as internal growth which increased headcount and operations.


    COST OF REVENUES.  For the year ended December 31, 1998, cost of revenues of
AppNet was $11.7 million as compared to the cost of revenues of Software
Services Corporation for the year ended December 31, 1997 of $8.4 million. The
change of $3.3 million was primarily driven by the increase in billable
headcount resulting from the acquisitions that occurred during 1998 and internal
growth.


    SELLING AND MARKETING.  Selling and marketing expenses for the year ended
December 31, 1998 were $1.0 million as compared to $1.0 million for Software
Services Corporation for the year ended December 31, 1997.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses of AppNet
were $6.5 million for the year ended December 31, 1998 as compared to $3.0
million of Software Services Corporation for the year ended December 31, 1997.
The difference is primarily a result of the acquisitions that occurred during
1998.

    STOCK-BASED AND OTHER ACQUISITION-RELATED COMPENSATION.  For the year ended
December 31, 1998, stock-based and other acquisition-related compensation of
AppNet was $1.2 million, which represents an accrual for the estimated amount of
cash and stock-based contingent consideration to be paid to former stockholders
of acquired businesses.

    DEPRECIATION AND AMORTIZATION.  For the year ended December 31, 1998,
depreciation and amortization of AppNet was $10.2 million as compared with $0.3
million for the year ended December 31, 1997. The change is primarily a result
of the amortization of intangible assets recorded by AppNet in connection with
the acquisitions made in 1998.

    INTEREST EXPENSE.  Interest expense of AppNet for the year ended December
31, 1998 was $1.1 million that primarily resulted from the interest on the
outstanding balance on the credit facility during the period.

    OTHER EXPENSE, NET.  Other expense of $0.7 million includes a charge of $0.3
million related to the refinancing of our credit facilities in 1998. Other
expense also includes the write-off of $0.3 million related to an investment in
a joint venture that was deemed to have no value due to the failure of the
venture to generate a customer base and to generate sufficient revenues to cover
operating expenses, which resulted in the abandonment of the operations of the
venture.

    INCOME TAXES.  Income tax benefit for the year ended December 31, 1998 was
$0.2 million. The effective income tax rate of 1.4% was lower than the blended
federal and state statutory rate primarily as a result of amortization of a
portion of our intangible assets which are not deductible for income tax
purposes and the recognition of a valuation allowance in accordance with
generally accepted accounting principles.

SOFTWARE SERVICES CORPORATION (PREDECESSOR COMPANY)

PERIOD ENDED AUGUST 24, 1998 COMPARED TO THE YEAR ENDED DECEMBER 31, 1997

    REVENUES.  Revenues for the period ended August 24, 1998 were $10.8 million,
compared to $13.3 million for the year ended December 31, 1997. The decrease is
primarily due to the fact that we are comparing a 12-month period to an
eight-month period, offset by increased activity in SSC's technical consulting
group.

    COST OF REVENUES.  Cost of revenues for the period ended August 24, 1998 was
$7.4 million, compared to $8.4 million for the year ended December 31, 1997. The
amount as a percentage of revenues remained relatively consistent between the
respective periods.

                                       33
<PAGE>
    OPERATING EXPENSES.  Total operating expenses for the period ended August
24, 1998 were $5.3 million, compared to $4.4 million for the year ended December
31, 1997, representing an increase of $0.9 million. The increase is a result of
a $2.7 million stock-based and acquisition-related compensation charge, incurred
in connection with the acquisition of SSC by AppNet. The offsetting decrease is
a result of the decrease in selling and marketing and general and administrative
expenses of $1.6 million as larger projects required less overall support.

    INCOME TAXES.  An income tax benefit of $0.6 million was recorded for the
period ended August 24, 1998, compared with an income tax provision of $0.4
million for the year ended December 31, 1997 based on the income(loss) before
income taxes for the respective period.

YEAR ENDED DECEMBER 31, 1997 COMPARED TO THE YEAR ENDED DECEMBER 31, 1996

    REVENUES.  Revenues for the year ended December 31, 1997 were $13.3 million,
compared to $11.8 million for the year ended December 31, 1996. The increase of
$1.5 million is a result of an increase in the number of projects completed and
amount of professional services rendered during 1997.

    COST OF REVENUES.  Cost of revenues for the year ended December 31, 1997 was
$8.4 million, compared to $7.7 million for the year ended December 31, 1996. The
amount as a percentage of revenues remained substantially consistent.

    OPERATING EXPENSES.  Total operating expenses for the year ended December
31, 1997 were $4.4 million, compared to $4.0 million for the year ended December
31, 1996, representing an increase of $0.4 million. The increase is a result of
the overall increase in general and administrative expenses for the year ended
December 31, 1997.

    INCOME TAXES.  An income tax provision of $0.4 million was recorded for the
year ended December 31, 1997, compared with a provision of $0.1 million for the
year ended December 31, 1996. The increase is a result of the increase in income
before income taxes for the respective period.

LIQUIDITY AND CAPITAL RESOURCES

    At March 31, 1999, we had approximately $5.7 million in cash and cash
equivalents. AppNet has financed its operations and acquisitions primarily
through the issuance of preferred stock, borrowings under credit facilities and
the issuance of common stock. For the year ended December 31, 1998, cash used in
operations was $2.6 million and $71.7 million was used in investing activities.
For the three months ended March 31, 1999, cash provided by operating activities
was $1.5 million and cash used in investing activities was $27.3 million. The
principal use of cash in investing activities was to finance acquisitions. As
AppNet continues to grow its business and integrate the businesses it has
acquired, AppNet expects to use cash from operations to fund these activities.

    Net cash provided by financing activities was $76.7 million and $29.0
million during the year ended December 31, 1998 and the three months ended March
31, 1999, respectively. We received proceeds from net borrowings under our
credit facilities of $37.5 million and $21.9 million during the year ended
December 31, 1998 and the three months ended March 31, 1999, respectively. In
addition, we received $36.3 million and $3.0 million as consideration for the
issuance of our preferred and common stock, respectively, during the year ended
December 31, 1998. Additionally, we received $7.0 million during the three
months ended March 31, 1999 as consideration for the issuance of preferred
stock.

    In connection with five of our acquisitions, LOGEX International, Century
Computing, Incorporated, Research & Planning, Inc., The Kodiak Group and i33
communications corp., we issued notes to the selling stockholders all of which
are convertible into shares of our common stock except for the notes issued in
connection with our acquisition of Research & Planning. The balance of the

                                       34
<PAGE>
notes at March 31, 1999 was approximately $15.6 million, $14.6 million of which
is convertible into shares of our common stock. These notes have varying
maturities, from October 1999 through April 2003, and bear interest at rates
between 4.33% and 8.0% as of March 31, 1999. In addition, in connection with the
acquisition of Software Services Corporation, we issued shares of Class B
Preferred Stock. The holders of Class B Preferred Stock are entitled to a 6%
cumulative dividend.


    At December 31, 1998, our revolving credit facilities provided for
borrowings up to $40 million. In 1999, we replaced these facilities with two new
revolving credit facilities which provide for up to $66 million in borrowings,
$40 million of which has been guaranteed by an affiliate. The new revolving
credit facilities will expire on August 24, 2001. The guaranteed portion bears
interest, at our option, at LIBOR plus 2.5% or the lenders' prime rate plus
0.5%. The unguaranteed portion bears interest, at our option, at LIBOR or the
lenders' prime rate plus an applicable margin based on our operating
performance. The credit facilities are secured by all of our assets and contain
various restrictive covenants that, among other things, require us to maintain
specified financial ratios and levels of liquidity and working capital and
restrict us from paying dividends to our common stockholders. At March 31, 1999,
approximately $4.1 million remained available for borrowing under our credit
facilities based on the level of financial ratios, as set forth in the credit
facility.


    We plan to use the proceeds of this offering to repay all outstanding
borrowings under our credit facilities. We intend to terminate our $40 million
credit facility following the consummation of this offering and amend our $26
million credit facility to provide for maximum aggregate revolving borrowings of
up to $20 million. The termination and amendment of these credit facilities will
reduce our interest expense in future periods. In conjunction with the
modification of these facilities, we may incur a charge of up to $0.6 million
representing the write off of financing costs related to these facilities which
have been capitalized and are not fully amortized as of March 31, 1999.

    AppNet's capital expenditures for 1998 were approximately $1.2 million.
Historically, capital expenditures have been used to make leasehold improvements
to AppNet's leased office space and to purchase computer hardware and software
and furniture and fixtures. AppNet does not have any material commitments for
capital expenditures for the foreseeable future. However, AppNet does plan to
make capital expenditures, which may include office space, over the next two
years to further develop our electronic commerce outsourcing services.

    During the period from the consummation of this offering through November
2000, we may be required to make contingent payments to former owners of six of
the businesses we acquired, LOGEX International, New Media Publishing, Sigma6,
Salzinger & Company, Internet Outfitters and TransForm IT. These contingent
payments are payable in cash and stock, in one case at the option of the selling
stockholders. The amount of these payments will depend on the level of
achievement of the operating targets and the market price of our common stock.
The majority of the former stockholders must remain employed by us in order to
remain eligible to receive these payments. The maximum aggregate amount of the
cash portion of these payments, assuming the operating targets are fully met, is
approximately $20 million.

    Based upon current expectations, we believe amounts which may be borrowed
under our credit facility and cash flow from operations will be adequate for us
to meet our capital requirements, to finance the cash portion of our contingent
payments and pursue our business strategy for the next 18 months. To the extent
AppNet is unable to fund its operations from cash flows and existing credit
facilities during or following the next 18 months, it may need to obtain
financing from external sources either by issuing additional equity or incurring
additional indebtedness.

RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivatives and Hedging Activities", which establishes
accounting and reporting standards for derivative

                                       35
<PAGE>
instruments, including derivative instruments embedded in other contracts, and
for hedging activities. SFAS No. 133 is effective for all fiscal quarters of
fiscal years beginning after June 15, 1999. We have not yet determined whether
the adoption of SFAS No. 133 will have a material effect on our results of
operations, financial position or cash flows.

YEAR 2000

    We have completed a preliminary assessment of our Year 2000 readiness and
are beginning to make our systems Year 2000 compliant. The risks posed by the
Year 2000 issue could adversely affect our business in a number of significant
ways. Many of our clients and potential clients maintain their operations on
systems that could be impacted by Year 2000 problems. If our clients fail to
ensure their systems are Year 2000 compliant and Year 2000 problems materially
adversely affect them, our business could be adversely affected, particularly if
demand for our services declines as companies spend their resources to upgrade
their computer systems. We rely on our suppliers for hardware, software and
services. Our business could be adversely affected if we cannot obtain products,
services or systems that are Year 2000 compliant when we need them. We also
depend on the availability of the Internet infrastructure to conduct our
business and provide services to our clients. Disruptions in the Internet
infrastructure arising from Year 2000 problems could materially adversely affect
our business, financial condition and results of operations. In addition, our
solutions are sometimes dependent upon third-party products and components.
Failure of a third party whose products or services we employ to adequately
address Year 2000 issues could result in our involvement in litigation
concerning our products and services or those of a third party. Futhermore,
because we provide computer-related services, the risk we will be involved in a
lawsuit relating to Year 2000 issues is likely to be greater than that of
companies in other industries. We sometimes provide express warranties to
clients that our work is Year 2000 compliant.


    We are in the process of obtaining assurances from our suppliers that they
are Year 2000 compliant. We have established a Year 2000 Executive Steering
Committee, appointed a Year 2000 Compliance Program Manager and adopted a formal
compliance program to oversee and coordinate our Year 2000 compliance efforts
throughout our organization. This program is designed to ensure consistency and
minimize the impact of Year 2000 problems on our operations. Our Year 2000
compliance program consists of the following five phases: awareness, assessment,
remediation, testing and implementation. Based on the early stages of our Year
2000 compliance program, we cannot estimate the percentage of completion for
each of these phases.


    In the event the Company does not complete the phases of its program, the
Company may fail to meet contractual obligations, provide adequate service or
meet customer requirements. The result of such failures could make the Company
subject to litigation for which the amount of potential liability and lost
revenue cannot be reasonably estimated at this time.

    Our costs in connection with Year 2000 compliance to date are approximately
$90,000. At this time, we estimate the potential costs of becoming Year 2000
compliant to be between $0.2 million and $0.6 million, which includes the cost
to replace hardware and software, outside consulting services and some internal
labor costs. However, as we continue to implement our Year 2000 compliance
program, these cost estimates may need to be significantly revised, which could
have a material adverse effect on our business, financial condition or results
of operations.

    As part of our plan to integrate the back-office functions of the businesses
we have acquired, we are implementing new, uniform internal information systems,
such as general ledger, billing, accounts payable and payroll, throughout our
organization. Although we have received assurances from our vendors that these
new systems are Year 2000 compliant, our internal systems may experience
operational difficulties because of undetected errors or defects in the
technology used.

                                       36
<PAGE>

    If we fail to address a Year 2000 compliance problem in one of our systems,
the result could be a failure or interruption of normal business operations. We
believe that our Year 2000 compliance program, when fully implemented, should
minimize the risk of significant interruptions to our operations. Currently, we
do not have an expected completion date for our compliance program. At this
point, we believe that the most reasonably likely worst case scenario may
involve areas we do not directly control, such as:


    - Our suppliers may provide inaccurate or misleading information to us with
      respect to their products' and/or services' Year 2000 compliance. If we
      had to replace every information technology system developed by a third
      party throughout our organization, we estimate the cost to be $7.2 million
      and that it would result in significant interruption of our operations.

    - Our clients may fail to ensure that their systems are Year 2000 compliant,
      which may cause the Year 2000 problem to materially adversely affect them.
      If this did occur, demand for our services could decline as companies
      spend their resources to upgrade their computer systems.

    - The failure of third-party products and components upon which our
      solutions are sometimes dependent could result in our involvement in
      litigation concerning our solutions or the products and components of
      third parties. We cannot accurately predict the outcome of any legal
      claims in which we may become involved as a result of such failure.

    - Critical utilities such as electrical power and telecommunications may be
      interrupted for a significant and protracted period of time. We have taken
      steps to mitigate these risks by installing back-up power supplies and
      redundant telecommunications. However, we could still be adversely
      impacted by failures at companies that provide us with Internet services.


    We currently do not have contingency plans in place in the event we do not
complete all phases of our Year 2000 compliance program. If we do not develop
our contingency plans, our potential Year 2000 liabilities may be materially
increased.


QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

    AppNet is exposed to market risk related to changes in interest rates on its
long-term credit facilities. AppNet is able to manage its interest rate risk to
some degree through management's option to select the factor used to determine
its interest rate. AppNet's credit facilities are variable rate credit
facilities. The guaranteed portion of our credit facilities bears interest, at
our option, at LIBOR plus 2.5% or the lenders' prime rate plus 0.5%. The
unguaranteed portion bears interest, at our option, at LIBOR or the lenders'
prime rate plus an applicable margin based on our operating performance. The
balance outstanding as of December 31, 1998 was $37.5 million, of which $19.7
million bears interest at a rate of 8.25% and $17.8 million bears interest at a
rate of 7.75%. Assuming the amount outstanding at March 31, 1999, which was
$59.4 million, was outstanding for the entire year, we estimate that a one
percentage point change to the weighted average interest rate at March 31, 1999
(8.0%) would equal a $0.6 million change in interest expense. If the interest
rate increased, the net loss attributable to common stockholders for the three
months ended March 31, 1999 would have increased by $0.2 million to $17.5
million.

    AppNet provides Internet and electronic commerce professional services and
solutions to medium-sized and large businesses. We develop electronic commerce
solutions that improve communication and commerce between businesses and
consumers as well as among businesses and their trading partners. We focus on
maximizing the opportunities presented by the Internet and electronic commerce
to enhance all aspects of our clients' operations, from the front end of their
business, creative Website design, to the back end, back-office integration of
existing systems and electronic commerce outsourcing, creating an end-to-end
solution. We were formed in 1997 as a Delaware corporation.

    Our professional services include:

    - strategic consulting;

    - interactive media services such as creative Website design and
      development, branding, which is the creation of a unique corporate
      identity for a client and its products, media planning and buying;

    - Internet-based application development, which is the development of
      software applications that are capable of running on the Internet and are
      written in languages such as Java, C++ and Visual Basic;

    - electronic commerce systems integration, which is the integration of
      electronic commerce systems, which are systems that automate the receipt,
      processing and delivery of transaction data and other information, with
      other corporate software and computer-based applications; and

    - electronic commerce outsourcing, which is the performance of electronic
      commerce services that would otherwise be handled by the client's internal
      staff using the client's resources.

INDUSTRY BACKGROUND

    The rapid growth in the use of the Internet and electronic commerce has
revolutionized the way businesses operate and interact with their customers and
trading partners. The Internet and electronic commerce have created new channels
of communication and distribution which raise the level and increase the speed
of interaction between a business and its trading partners and customers. The
demand for Internet and electronic commerce services is increasing as more and
more companies develop on-line businesses and employ Internet and electronic
commerce solutions.

    The Internet enables businesses to establish an on-line presence through
which they can offer new and complementary products and services to new and
existing markets. As a result, businesses have been able to create new sources
of revenue, improve customer care and retention and streamline their internal
operations by processing orders and payments on-line.

    To date, businesses have primarily focused on using Internet and electronic
commerce solutions to improve business-to-consumer relationships. However,
businesses are increasingly using the Internet and electronic commerce to open
cost-effective, reliable, highly efficient channels of communication and
commerce with their suppliers and distributors. Internet and electronic commerce
solutions can improve the way businesses interact with their trading partners by
linking businesses' back-office systems through electronic data interchange, or
EDI, and the Internet to trading partners and suppliers. EDI is a process
through which data is transferred from a paper format into a standard electronic
format and electronically transmitted to trading partners over a private network
or the Internet. In July 1997, International Data Corporation reported that 80%
of Fortune 500 companies employed EDI to improve their business processes.
Businesses are increasingly finding that they can reliably and cost-effectively
manage a high volume of transactions on a real-time basis using EDI and the
Internet.

                                       38
<PAGE>
In addition, by using EDI and the Internet for communication with both consumers
and trading partners, businesses are creating electronically integrated supply
chains that significantly improve their operating efficiency.

    Businesses are increasingly discovering that implementing Internet and
electronic commerce solutions is necessary to remain competitive and are
demanding end-to-end Internet and electronic commerce solutions that can improve
every aspect of their operations. As a result, technology industry research
firms predict that the market for Internet and electronic commerce services
worldwide will grow significantly over the next few years. International Data
Corp. estimates that this market will increase from $4.6 billion in 1997 to
$43.7 billion by 2002, which represents a compound annual growth rate of 57%.
According to a 1998 Dataquest survey of selected Fortune 1000 companies, 83% of
such companies are currently investing, or plan to invest, in Internet solutions
and 48% are currently investing, or plan to invest, in electronic commerce
solutions.

    Most businesses rely on outside specialists to design and develop Internet
and electronic commerce solutions for a number of compelling reasons. Because
Internet and electronic commerce technologies have developed so rapidly, few
businesses have employees with the advanced skills necessary to effectively
evaluate and implement these technologies successfully. Given the pressure to
get to market quickly, waiting for in-house employees to be trained to use these
technologies is not practicable. In addition, hiring trained professionals is
difficult because they are in great demand. At the same time, as business
challenges grow increasingly complex, so must the Internet and electronic
commerce solutions required to address them. Given the significant cost to
design, develop, implement and manage Internet and electronic commerce
solutions, businesses cannot afford to expend resources developing solutions
themselves. Hiring a firm that provides a comprehensive range of Internet and
electronic commerce professional services is often the most efficient and
cost-effective solution for many companies.

THE APPNET SOLUTION

    Our goal in founding AppNet was to address the growing need for end-to-end
Internet and electronic commerce solutions. We offer a comprehensive range of
services involving the design, development, implementation and management of
Internet and electronic commerce solutions that facilitate and promote
communication and commerce between businesses and consumers as well as among
businesses and their trading partners. Key elements of the AppNet solution are:

    - END-TO-END SERVICE OFFERING

    We can provide clients with end-to-end Internet and electronic commerce
solutions. Our clients recognize significant cost and time savings and receive
integrated solutions because they can obtain all of the Internet and electronic
commerce professional services they need from one company.

    - UNIQUE ELECTRONIC COMMERCE OUTSOURCING SERVICES

    We offer our clients an extensive range of electronic commerce outsourcing
services as part of our overall service offering. We perform electronic commerce
services that would otherwise be handled by the client's internal staff using
the client's resources. Our business-to-business outsourcing services include
processing transactions for our clients using our resources and infrastructure.
We also operate electronic data interchange programs through which businesses
and their trading partners exchange information electronically. We monitor and
analyze the transactions processed through these programs. Our
business-to-consumer outsourcing services include managing on-line stores,
processing transactions, managing and hosting Websites and operating and
managing electronic commerce systems. Our Website managing and hosting services
include adding and editing material on a Website and making sure the Website is
operating according to its specifications. Our outsourcing services include
maintaining security at a Website by ensuring only authorized users have access
to the Website. We also store data that is generated by activity at the Website.
Clients who take advantage of these services get to market

                                       39
<PAGE>
quickly; do not have to make the significant financial and technological
investments required to effectively build and manage their own infrastructures;
receive reliable and secure services; and can focus their attention and
resources on their core competencies.

    - ABILITY TO SOLVE INCREASINGLY COMPLEX BUSINESS PROBLEMS

    Our business-level and process-level strategic consulting services help our
clients solve their increasingly complex business problems with sophisticated,
vendor-neutral Internet and electronic commerce solutions. We employ
business-level strategic consulting services to develop and redefine clients'
business models to incorporate Internet and electronic commerce strategies. We
employ process-level strategic consulting services to improve the business
processes of clients who have already incorporated Internet and electronic
commerce strategies into their business models. These services, together with
the knowledge and experience we gain designing, developing, implementing and
managing each electronic commerce solution, enable us to develop comprehensive
strategies for growing on-line ventures, streamlining on-line marketing and
distribution strategies, improving operating efficiencies and reducing costs.

    - ENHANCED SERVICES THROUGH THE USE OF ADVANCED PROPRIETARY TECHNOLOGIES

    We use advanced proprietary technologies to design and develop more
effective Internet and electronic commerce solutions. ClientLink, a secure
Website we developed that is accessible only by us and our clients, also known
as an extranet, gives our clients on-line access to, and engages their active
participation in, the development of their Internet and electronic commerce
solutions. Within ClientLink, clients can, on a real-time basis, view any
changes that have been made to their solutions, communicate electronically with
project team members and check a calendar for information regarding product
reviews and launches. We use ClientLink to raise the level of interaction
between us and our clients, which, in turn, improves the quality, functionality
and adaptability of the solution we create.

    AdMaximize, our proprietary interactive media service, enables us to
measure, on a real-time basis, a client's return on investment for its on-line
advertising dollars. AdMaximize tracks the performance of ads on the Internet
and collects real-time data on the number of users who click on the ad, the
number of new customers and the amount of sales generated by the ad. Based on
their analysis of this information, clients can make real-time adjustments to
their advertising campaigns to maximize the number of users who visit their
Websites and reduce the costs of acquiring new customers and generating sales.

    As part of the outsourcing services we offer, we utilize proprietary
software, EDI Control/400 and STAR, in order to more effectively manage
electronic data interchange programs that process a high volume of transactions.
EDI Control/400 enables us to monitor and analyze our clients' transactions and
communications with their trading partners with fewer people and higher service
levels. Our client support services team uses STAR, or the Service Tracking and
Reporting System, to log, track and report on all aspects of a transaction.

    - REUSABLE BUSINESS SOLUTIONS

    We have developed reusable business solutions in the process of designing,
developing, implementing and managing end-to-end Internet and electronic
commerce solutions for clients in a number of industries. These reusable
business solutions were developed based on our industry-specific expertise and
utilize reusable software code and content objects. These solutions enable us to
give our clients the benefit of our knowledge and experience in addressing
complex business challenges, develop and implement Internet and electronic
commerce solutions more quickly and efficiently, focus our efforts on
customizing solutions to meet our clients' specific needs and deliver reliable
solutions based on components that have been tested and perfected through
repeated use in other solutions.

                                       40
<PAGE>
OUR STRATEGY

    Our goal is to become the most recognized and sought-after provider of
Internet and electronic commerce services to medium-sized and large business
clients. To achieve this goal we plan to:

    - EXPAND CLIENT RELATIONSHIPS

    We plan to cross-sell our comprehensive range of Internet and electronic
commerce professional services to existing clients. We believe that if we
continue to provide sophisticated solutions to our clients:

    - our existing clients will increase the amount, scope and complexity of
      services they obtain from us;

    - we will strengthen our reputation as a creative source for Internet and
      electronic commerce solutions; and

    - we will attract new clients through referral-driven sales.

This strategy should increase our revenue predictability and result in
additional and more extensive engagements with our clients.

    - INCREASE REPEAT AND RECURRING REVENUES

    Our strategy is to increase the proportion of our revenues which represents
repeat business with the same clients as well as the proportion of our recurring
revenues from our electronic commerce outsourcing services. We intend to
generate repeat revenues by cross-selling services and entering into multiple
engagements with our existing clients. In addition, we plan to increase
recurring revenues by selling additional electronic commerce outsourcing
services to our new and existing clients. We charge clients who use our
electronic commerce outsourcing services either a fixed monthly rate or on a per
transaction basis, or both. Our target contract length for electronic commerce
services is one year. Increasing repeat and recurring revenues will enable us to
predict our revenues with greater accuracy and improve our operating margins.

    - BUILD AND ENHANCE COMPLEMENTARY SKILL SETS AND MAINTAIN TECHNOLOGICAL
      EXPERTISE

    Each additional skill set we develop improves our ability to better serve
our existing and future clients. We believe it is imperative for us to stay
abreast of the newest technological developments and evolving service offerings
in order to maintain the high level of quality of our services, increase the
effectiveness of our solutions and attract and retain qualified employees. We
continually research, test and evaluate new Internet and electronic commerce
technologies which we can incorporate into our solutions. Each engagement we
complete broadens our expertise and increases our knowledge, thereby enhancing
our ability to provide the most effective Internet and electronic commerce
solutions.

    - EXPAND AND STRENGTHEN MARKETING AND TECHNOLOGY RELATIONSHIPS WITH LEADING
      TECHNOLOGY VENDORS

    We intend to further expand our marketing and technology relationships with
several leading technology vendors and build other relationships that will
promote our growth and enhance our position in the marketplace. We have
relationships with vendors such as Harbinger, Microsoft, Oracle, SAP and TSI
International Software. Our marketing relationships with these technology
vendors generally contemplate that we will engage in joint marketing programs to
cross-sell our services. Our technology relationships with these technology
vendors generally contemplate that vendors will give us access to products which
are still being developed in exchange for our feedback about such products. Our
non-exclusive marketing and technology relationships with technology vendors
help us generate business by increasing our name recognition and visibility in
the marketplace, providing us with new sales opportunities and early access to
the newest technologies, enabling us to cross-sell our services with prominent
technology vendors and increasing our access to vendor technical training and
support.

                                       41
<PAGE>

We do not depend, however, on any one or all of these relationships to generate
business. While we do not derive revenues directly from these relationships,
from time to time we receive sales leads and client referrals from these
vendors.


    - PURSUE CLIENT-DRIVEN GEOGRAPHIC EXPANSION

    We intend to open additional offices both domestically and internationally
in order to better serve clients in locations where we have already attracted
business. This allows us to serve clients locally, cross-sell services to
existing local clients and win more local business. Each new office we have
opened has enhanced our ability to attract and service large clients and to hire
additional staff without relocation burdens. We currently have offices in 14
locations in the U.S., including the metropolitan areas of Boston, Denver,
Detroit, Los Angeles, New York City and Washington, DC.

    - EXPAND AND DEVELOP INDUSTRY-SPECIFIC EXPERTISE

    Through our experience designing, developing, implementing and managing
Internet and electronic commerce solutions for a wide variety of companies, we
have gained significant strategic knowledge and created industry-specific
reusable business solutions. This industry-specific expertise significantly
enhances our ability to help other companies in the same industries successfully
adopt Internet and electronic commerce solutions. To date, we have developed
reusable business solutions for the retail services, financial services,
healthcare, manufacturing and telecommunications industries. We intend to
broaden the range of industries in which we have specialized knowledge and
maximize the benefits to our clients of such knowledge by creating additional
industry-specific solution templates and reusable software. We employ strategic
consultants, sales, marketing and technical staff with expertise in industries
which we believe can realize significant benefits from Internet and electronic
commerce solutions. Further developing and strengthening this expertise will
increase our knowledge of industry specific business challenges and increase the
industry-targeted services we can offer, thereby improving our ability to
penetrate specific industries.

    - ATTRACT AND RETAIN A HIGHLY SPECIALIZED WORKFORCE

    We will continue to recruit highly skilled and experienced professionals who
have industry-specific expertise and who are proficient in a broad range of
technological and business skills. We intend to continue to ensure that our
employees have the requisite expertise to provide our clients with a
comprehensive range of Internet and electronic commerce professional services.
We have 11 full-time recruiters and often use recruitment firms as well. We also
attract employees through referral bonus programs and advertising on the
Internet. We plan to retain and motivate our employees by giving them the
opportunity to work with cutting-edge technologies, paying competitive
compensation packages, granting stock options, reimbursing tuition expenses and
encouraging a corporate culture that is results-driven and rewards creativity,
communication and cooperation.

[Diagram entitled "Strategic Consulting" outlining the interaction among AppNet
Systems, Inc.'s broad-based service offerings, including "Interactive Media
Services," "Internet-Based Application Development Services," "Electronic
Commerce Systems Integration Services" and "Electronic Commerce Outsourcing
Services."]


    -  STRATEGIC CONSULTING

        Our business- and process-level strategic consulting services help our
    clients successfully develop on-line businesses and improve their overall
    business processes. We employ business-level strategic consulting to study
    and analyze our clients' market position, operating requirements, systems
    and capabilities to determine how our clients should use the Internet and
    electronic commerce to accomplish their objectives. We work with clients to
    incorporate Internet and electronic commerce solutions into their businesses
    and assist in developing on-line businesses and on-line marketing
    strategies. We employ process-level strategic consulting with clients that
    have already incorporated Internet and electronic commerce solutions into
    their businesses to assist them in improving their overall business
    processes by incorporating on-line system architecture and design with
    existing Internet and electronic commerce solutions, thereby improving
    operating efficiencies and reducing costs.

    -  INTERACTIVE MEDIA SERVICES


        Our interactive media services include creative Website design and
    development, branding, which is the creation of a unique corporate identity
    for a client and its products and developing on-line advertising strategies.
    Developing on-line advertising strategies includes media buying and
    planning, on-line ad placement, management, tracking and reporting and
    on-line promotion and campaign development. As part of an on-line
    advertising strategy, we also develop affinity programs that link businesses
    by rewarding one business' clients with products and services of another
    business. These services are designed to maximize our clients' return on
    their investments in on-line businesses by generating and increasing the
    number of visitors to a Website, enhancing user experience and increasing
    the effectiveness of our clients' marketing efforts. We integrate these
    services into our clients' overall solutions.


    -  INTERNET-BASED APPLICATION DEVELOPMENT

        Internet-based application development is the development of software
    applications that are capable of running on the Internet and are written in
    languages such as Java, C++ and Visual Basic. These services are designed to
    help our clients rapidly develop highly flexible and cost-effective business
    applications. We develop corporate intranets, which are secure Websites
    accessible only within a particular company, and electronic commerce systems
    and we Web-enable legacy systems, which are existing systems, so that they
    can operate on the Internet. We design and develop more effective Internet
    and electronic commerce solutions by giving our clients on-line access to
    the development of their solutions. We design, build and implement solutions
    that are secure, adaptable and easy to use and manage.

    -  ELECTRONIC COMMERCE SYSTEMS INTEGRATION

        Electronic commerce systems integration is the integration of electronic
    commerce systems, which are systems that automate the receipt, processing
    and delivery of transaction data and other information, with other corporate
    software and computer-based applications such as Websites and accounting and
    financial systems. These services are designed to rapidly install and
    integrate our

                                       43
<PAGE>
    solutions with our clients' existing operations so our solutions become an
    integral part of our clients' critical business systems. We install our
    solution, convert all necessary data, perform acceptance testing and put the
    system into operation. We also integrate the solution with back-office
    existing legacy systems to ensure that each client's computer-based
    applications operate seamlessly and with maximum security.

    -  ELECTRONIC COMMERCE OUTSOURCING

        We perform electronic commerce services that would otherwise be handled
    by the client's internal staff using the client's internal resources. Our
    electronic commerce outsourcing services help clients rapidly launch and
    implement electronic commerce solutions and then cost-effectively manage,
    operate, maintain and continue to develop those solutions. We provide
    business-to-business outsourcing services such as operating electronic data
    interchange programs and transaction processing at our outsourcing center in
    Pittsfield, MA, as well as at our customer's sites. We provide
    business-to-consumer outsourcing services such as managing on-line stores,
    transaction processing, managing and hosting Websites and the ongoing
    management, technical operation, maintenance and development of electronic
    commerce solutions at our outsourcing center in Laurel, MD, as well as at
    our customer's sites.

ELECTRONIC COMMERCE OUTSOURCING CENTERS

    We believe our outsourcing capabilities are a key component of our full
range of Internet and electronic commerce professional service offerings and
differentiate us from our competitors. Outsourcing enables us to effectively
manage, operate and maintain the electronic commerce systems we have developed
for our clients. Fees from outsourcing services currently represent a small
portion of our revenues. However, we expect that demand for outsourcing services
will increase over time as customers recognize that outsourcing is a
cost-effective solution. For example, outsourcing is an attractive choice for
those customers who lack the internal resources required to effectively build
and manage their own infrastructure or their critical business processes and who
are under pressure to get to market quickly.

    At our business-to-business electronic commerce outsourcing center, we
process and manage thousands of transactions among hundreds of trading partners
on a variety of hardware and software platforms, over private networks, and the
Internet. We use EDI Control/400, our administrative software product, to
operate, monitor and analyze electronic data interchange programs through which
businesses and their trading partners exchange information electronically. EDI
Control/400 provides our customers with detailed transaction reporting, on-line
storage of data about the transactions, and multiple levels of security ensuring
only authorized user have access to and can exchange information. At our
business-to-consumer electronic commerce outsourcing center we manage on-line
stores, process transactions and manage and host Websites. Our Website managing
and hosting services include adding and editing material on a Website and making
sure the Website is operating according to its specifications.

    Our outsourcing centers operate seven days a week, 24 hours a day. Our
outsourcing center staff proactively manages and monitors the operation of each
center using network management software, including proprietary technologies we
developed. We collect, process and respond to systems-level event information
and build and maintain a central repository for inventory and asset management
information. In addition, each of our outsourcing centers features multiple
levels of security which we believe protect our clients' private information by
isolating our electronic commerce outsourcing centers from public network
infrastructures.

CLIENTS

    We market our services to medium-sized and large companies from a range of
industries which we believe can benefit from Internet and electronic commerce
solutions. Our engagements vary in scope from strategic consulting assignments
to designing and implementing complex and highly functional

                                       44
<PAGE>
intranets and extranets. Because we can offer every client a complete spectrum
of Internet and electronic commerce professional services, we can customize each
of our engagements to fit a client's specific needs. Two of our clients, Ford
and the U.S. Government, accounted for 15% and 12%, respectively, of our total
revenues for 1998. After giving pro forma effect to the acquisitions we made in
1998 and 1999 as if they had occurred on January 1, 1998, our top ten customers
would have represented approximately 35% of our 1998 pro forma revenues.

    Because of the strategic and competitively sensitive nature of the services
we perform for our clients, in many cases we have agreed to keep our clients'
identities confidential. Set forth below is a partial list of the clients to
whom we provided services in 1998 that we believe is representative of our
overall client base:

    The following examples illustrate the kinds of Internet and electronic
commerce solutions we have developed for specific clients.

THE ELECTRONIC IMAGING DIVISION OF TOSHIBA AMERICA INFORMATION SYSTEMS, INC.

    Solution: We developed the community, Web-interface and database elements of
Toshiba's FYI Dealer Extranet, an on-line system for dealers that provides a
common interface in addition to customized information that meets each
individual dealer's requirements. We designed security features which protect
market-sensitive information from unauthorized users. A conditional access
system, driven by a complex database user-authorization scheme, offers multiple
read-and-write user access levels. Employees, dealers and distributors have the
opportunity to build relationships on this Dealer Extranet. This electronic
commerce and informational site is designed to simplify ordering and shipping of
more than 10,000 spare-part SKUs for fax machines and copiers.


BURTON SNOWBOARDS

    Challenge: Design and implement an on-line inventory and supply-chain
management system.


    Solution: We designed and implemented an on-line inventory and supply-chain
management system that Burton management uses to control changing inventory,
manage materials and track product placement. Our solution accommodates multiple

is designed to improve Burton's efficiency in managing its inventory and
supply-chain and reducing production overruns and overall costs.

    Challenge: Design, implement and operate an EDI program that would
accurately process and track orders, shipping notices, invoices and other time
sensitive data, including point-of-sale information, to support streamlined
procurement and distribution center operations.


    Solution: We designed and implemented an EDI program for K*B Toys to manage
inventory levels and merchandise replenishment at over 1300 mall-based stores.

music guides, selectable music samples and management features for site update
and promotion and order management. Our solution is designed to build brand
recognition and loyalty and establish an additional distribution channel.


MULTEX SYSTEMS

    Challenge: Design and develop a Web-based ad campaign to increase site
traffic and trading volume and decrease the per customer acquisition cost.


    Solution: We crafted a media plan which included the creation of multiple
banner ads. Using our proprietary service, AdMaximize, we served banner ads,
tracked banner ad performance and collected real-time data on click-through,
lead generation, customer acquisition and sales. Based on Multex's and our
collective analysis of this data, we were able to make real-time adjustments to
Multex's ad campaign. Our solution is designed to increase overall membership
for Multex, increase its revenues per new member and decrease its cost to
acquire new members via the Web.

SALES AND MARKETING

    As of May 1, 1999, we employed 26 full-time sales professionals. Three
corporate sales professionals concentrate on our Internet and electronic
commerce professional services to clients in the industries in which they have
extensive expertise. The other 23 members of our sales force are service-focused
and concentrate on selling individual services as well as cross-selling all of
our service offerings. Our vice president of corporate sales coordinates the
efforts of our corporate and service-focused sales personnel.

    Our marketing strategy is to demonstrate to our potential clients the
advantages of Internet and electronic commerce solutions, and our expertise and
success in designing, developing, implementing and managing end-to-end
solutions. In addition, we have retained an outside public relations and
advertising firm to assist us with our marketing efforts on a company-wide
basis. Our two full-time corporate marketing professionals concentrate on
promoting and enhancing our brand on a nationwide basis. Our five full-time
service-focused marketing professionals concentrate on marketing a set of our
services, often to a targeted audience or in their local markets.

    Our sales and marketing strategy is built upon the following directives:

    - ENHANCE OUR BRAND AND IMPROVE OUR MARKET POSITIONING

        Our goal is to become the most recognized and sought-after provider of
    Internet and electronic commerce professional services to medium-sized and
    large business clients. To do so, we must continue to enhance our brand and
    reputation. Our brand development programs deliver the message that we are a
    national company with the experience and resources to meet all of our
    clients' Internet and electronic commerce services needs. To build and
    differentiate our brand, we use publicity campaigns that appear on the
    Internet, in print advertising, at trade shows and in educational white
    papers. We also take advantage of the opportunity to strengthen our brand by
    developing relationships with strategic partners. As we enhance our
    industry-specific expertise, we intend to develop sales and marketing
    programs targeted to specific industries.

    - MANAGE OUR CLIENTS' ACCOUNTS EFFECTIVELY

        Corporate sales professionals direct client leads to the appropriate
    service-focused salesperson. Our corporate sales professionals also manage
    accounts for large clients with multiple locations and ensure each part of
    our clients' accounts are served by the technical staff which can best meet
    their needs.

    - CROSS-SELL SERVICES


        As we integrate the diverse client bases of the companies we acquired,
    we intend to continue to take advantage of opportunities to cross-sell our
    services to existing clients. We intend to train every member of our sales
    force to cross-sell our entire range of services. In addition, we are
    creating uniform marketing and sales materials which describe the wide range
    of services we offer and position AppNet as a provider of end-to-end
    Internet and electronic commerce solutions.


    In each of our professional services engagements, a client can contract for
the specific services it requires. We bill most of our engagements on a time and
materials basis, although we have entered into several engagements on a
fixed-price basis. Clients who use our electronic commerce outsourcing services
are charged either a fixed monthly rate or on a per transaction basis, or both.

                                       48
<PAGE>
COMPETITION

    The markets for Internet and electronic commerce professional services are
relatively new, intensely competitive, quickly evolving and subject to rapid
technological change. We expect competition to continue and intensify in the
foreseeable future.

    Our competitors can be divided into several groups:

    - Internet professional services providers, such as Agency.com, iXL,
      Proxicom, Razorfish, Scient, Think New Ideas, US Interactive, USWeb/CKS
      and Viant;

    - large information technology consulting services providers, such as
      Andersen Consulting, Cambridge Technology Partners, CSC, EDS, IBM and
      Sapient;

    - interactive advertising agencies, such as Darwin Digital, Giant Step, Grey
      Interactive, Modem Media . Poppe Tyson and Thunderhouse;

    - electronic commerce software and service providers, such as BroadVision,
      Harbinger, Open Market and Sterling Commerce; and

    - Internet access and service providers, such as Abovenet, Exodus and
      Frontier/Global.

    We believe we can distinguish ourselves from our competitors by offering our
clients end-to-end Internet and electronic commerce solutions. We believe we can
compete effectively on the basis of our comprehensive range of services,
technical expertise, creative talent, brand or name recognition and the speed,
reliability and price of the services we provide. However, our competitors have
also begun to offer a variety of Internet and electronic commerce professional
services, rather than specialize in one area, or have announced their intention
to do so. These companies may continue to expand their operations so that they
offer a full range of business-to-business and business-to-consumer Internet and
electronic commerce professional services and products.

    There are relatively low barriers to entry into our business. We do not own
any patent technology that precludes or inhibits competitors from entering our
markets. The costs to develop and provide Internet or electronic commerce
professional services are low. Therefore, we expect to continue to face
additional competition from new entrants into our markets. Many of our
competitors have greater financial, technical, marketing and public relations
resources than AppNet. A number of our outsourcing competitors have made
substantial capital investments in their infrastructure. Because many of our
competitors have longer operating histories than we do, many of them also have
greater brand or name recognition, larger client bases and longer client
relationships on which they can rely for generating business.

ACQUIRED COMPANIES

    Our goal in founding AppNet was to build a company that could offer a
comprehensive range of Internet and electronic commerce professional services.
We began by developing a detailed strategic plan that identified the specific
professional services that are required to provide clients with end-to-end
solutions. These services were strategic consulting, interactive media services,
Internet-based application development, electronic commerce systems integration
and electronic commerce outsourcing. We then identified a group of companies
that excelled in providing services in one or more of these professional
services areas. After reviewing and evaluating over 100 companies, we ultimately
acquired a set of companies that we believe fit together strategically and
culturally and that, when integrated with one another, could design, develop,
implement and manage end-to-end solutions.

                                       51
<PAGE>
    In connection with our acquisition of Internet Outfitters, approximately
$1.45 million of the purchase price, based upon the fair value of $17.10 per
share at the date of acquisition, in the form of shares of our common stock was
pledged to us and escrowed to be available to satisfy any potential liability in
connection with a license dispute. We also held back $750,000 of the cash
purchase price to be used to satisfy indemnification claims, including any
potential liability arising from such license dispute. These amounts will be
paid on the earlier of the date the dispute is resolved in a manner satisfactory
to us or June 30, 2001. A licensor of software used by a client of Internet
Outfitters has asserted that Internet Outfitters caused the client to underpay
the licensor in the amount of $2.2 million. Outfitters has denied any liability
for those additional amounts. In management's opinion, based on all known facts,
the software licensor's claim is without merit, however, if disposed of
unfavorably to Appnet, it could materially adversely affect us.

TransForm IT on March 29, 1999. TransForm IT specialized in strategic

Transform Acquisition Corp., a subsidiary formed by AppNet to acquire TransForm
IT, are entitled to receive potential contingent payments payable in options to
purchase shares of our common stock based on the achievement of various revenue
levels during the 12-month period ending on March 31, 2000. During 1998,
TransForm IT had revenues of approximately $3.1 million.

    We have developed a detailed process to fully integrate each acquisition
into our existing operations and create one seamless organization. We have begun
completing the integration tasks laid out in this detailed process. This
detailed process focuses on integrating the delivery of our professional
services, our sales and marketing functions, our knowledge management system and
our back-office functions.

    By integrating the delivery of professional services, we can more
efficiently manage projects, provide better quality control, increase the
quality of our work and provide better customer service. By integrating our
sales and marketing functions, we can more efficiently generate leads and win
new business, provide superior customer service, coordinate the delivery of more
effective marketing messages and better train our sales personnel. By
integrating the way we manage our knowledge on a company-wide basis, we can more
efficiently interact and share information with our employees and customers,
reduce the time it takes to develop solutions for our clients, increase the
quality of our work and provide better customer service. By integrating our
back-office functions we can more efficiently monitor and manage our business,
recruit and retain employees, and administer corporate-wide benefit programs.

EMPLOYEES

    As of May 1, 1999, we had approximately 755 employees. Our continuing
success will depend in large part on our ability to attract, motivate and retain
employees who are qualified to offer the services we provide. Competition for
qualified employees is intense. We believe we have been successful to date in
attracting and retaining qualified employees. Our strategy for attracting,
motivating and retaining our employees is to pay competitive salaries and cash
bonuses, grant stock options, reimburse tuition expenses and encourage a
corporate culture that is results-driven and rewards creativity, communication
and cooperation.

    We believe our relationship with our employees is satisfactory. None of our
employees is represented by a union. Generally, our employees are retained on an
at-will basis and many of our key

                                       52
<PAGE>
employees are subject to employment agreements. All of our senior managers, as
well as most of our key employees, are required to sign confidentiality
agreements and non-competition agreements which prohibit them from competing
with us during their employment and for various periods thereafter.

PROPERTIES

    Our headquarters are located in Bethesda, MD and consist of approximately
13,400 square feet of leased space, the lease for which expires in May 2005. We
also lease office space in Santa Monica, CA, Golden, CO, Stamford, CT, Laurel,
MD, Cambridge, MA, Pittsfield, MA, Ann Arbor, MI, Detroit, MI, New York, NY,
Charlottesville, VA, Falls Church, VA, Vienna, VA and Amsterdam, The
Netherlands. We do not own any real estate. We do not consider any specific
leased location to be material to our operations and we believe that equally
suitable alternative locations are available in all areas where we currently do
business.

LEGAL PROCEEDINGS

    We are not a party to any pending material legal proceedings.

long as GTCR owns at least 15% of the shares owned by it immediately after the
consummation of the Offering, AppNet will nominate at least one GTCR designee to
the Board.


COMMITTEES OF THE BOARD OF DIRECTORS


    After completion of this offering, we intend to establish an Audit Committee

LIMITATIONS ON LIABILITY AND INDEMNIFICATION MATTERS

    The Delaware General Corporation Law provides that a company may indemnify
its directors and officers against liabilities they may incur as a result of
their service as a director of officer. Our certificate of incorporation and
bylaws provide for the indemnification of our directors and officers to the
fullest extent permitted by law. The effect of such provisions is to indemnify
our directors and officers against all costs, expenses and liabilities incurred
by them in connection with actions, suits or proceedings in which they are
involved because of their affiliation with us. In addition, we intend to obtain
director and officer liability insurance to effectuate these provisions.

EMPLOYMENT AGREEMENTS

    We have entered into a senior management agreement with Mr. Bajaj, dated as
of June 29, 1998, which provides for his employment as our President and Chief
Executive Officer until he resigns, is disabled, as determined by the Board of
Directors in its good faith judgment, dies or is terminated by the Board of
Directors for any reason. Mr. Bajaj began to receive an annual base salary of
$300,000 in May 1999, subject to increases as determined by the Board of
Directors based upon AppNet's achievement of budgetary and other objectives set
by the Board of Directors. He will also be eligible to receive a bonus of up to
50% of his salary based upon AppNet's achievement of budgetary and other
objectives set by the Board of Directors.

    The senior management agreement contains provisions requiring Mr. Bajaj to
protect the confidentiality of our proprietary and confidential information. In
addition, Mr. Bajaj is prohibited, during his employment at AppNet and for 18
months after such employment ends, from competing with AppNet, soliciting any of
our employees or interfering with any of our business relationships.

    The senior management agreement also restricts the transfer of all shares of
AppNet common stock Mr. Bajaj owned as of the date of the agreement until June
29, 2003, subject to specific exceptions, including:

    - sales in a registered public offering; and

    - sales, subject to volume limitations imposed by the senior management
      agreement, under Rule 144 under the Securities Act.

The registration agreement between AppNet and substantially all of its existing
stockholders dated as of June 29, 1998 states that Mr. Bajaj may request that
his shares of AppNet common stock be included on any registration statement
filed by AppNet:

    - to register common stock held by GTCR and Smart Technology; or

    - on its own behalf, other than in this offering.

    The senior management agreement provides that if Mr. Bajaj's employment with
us terminates before June 30, 2001, AppNet may repurchase shares of its common
stock owned by Mr. Bajaj or his permitted transferees at a price of $0.0029 per
share. The number of shares which AppNet may repurchase upon these terms is
2,036,632 until June 29, 1999, 1,358,109 until June 29, 2000 and 679,004 until
June 29, 2001, after which AppNet's right to repurchase Mr. Bajaj's common stock
terminates. If AppNet does not exercise its repurchase right, GTCR and Smart
Technology may repurchase these shares at a price of $0.0029 per share and
contribute them to AppNet in exchange for a promissory note equal to the
aggregate purchase price of such shares. GTCR's and Smart Technology's
repurchase right terminates upon the earliest of:

    - the sale of capital stock with the voting power to elect a majority of the
      Board of Directors to persons or entities other than GTCR and Smart
      Technology, other than in a public offering;

    - the sale of all or substantially all of our assets;

    - GTCR and its affiliates failing to own more than 50% of the common stock
      GTCR purchased under the Purchase Agreement dated June 29, 1998, as
      amended; and

    - June 30, 2001.

    AppNet also has the right, under Mr. Bajaj's senior management agreement, if
it issues or sells common stock or rights to acquire common stock to its
employees, to repurchase up to 1,251,228 shares of common stock at a price of
$0.3007 per share from Mr. Bajaj, whether held by Mr. Bajaj or his permitted
transferees, to be issued or sold to such employees. As of May 1, 1999, AppNet
had repurchased a total of 1,041,109 of such shares from Mr. Bajaj for an
aggregate purchase price of

                                       58
<PAGE>
$313,035. Upon the termination of Mr. Bajaj's employment, AppNet has the right
to repurchase all of this common stock, whether held by Mr. Bajaj or his
permitted transferees. AppNet's rights to repurchase this common stock terminate
upon consummation of this offering.

    We have entered into senior management agreements with each of Messrs.
Tobaccowala, McCalley, Alexander, McManus and Harvey. These agreements provide
for their respective employment by AppNet until resignation, disability, as
determined by the Board of Directors in its good faith judgment, death or
termination by the Board of Directors for any reason. Each senior management
agreement sets forth the annual base salary the executive is entitled to
receive, subject to increases as determined by the Board of Directors based upon
AppNet's achievement of budgetary and other objectives set by the Board of
Directors. Each executive is eligible to receive a bonus of up to 50% of his
salary based upon AppNet's achievement of budgetary and other objectives set by
the Board of Directors.

    If an executive's employment is terminated without cause, he is entitled to
receive his annual salary and life, medical and disability insurance benefits
for one year. Cause is defined generally as:

    - commission of a felony or crime involving moral turpitude;

    - fraud, gross negligence or willful misconduct with respect to AppNet;

    - substantial and repeated failure to perform duties; or

    - breach of the confidentiality or noncompete provisions of the senior
      management agreement.

    Each senior management agreement contains provisions requiring the executive
to protect the confidentiality of our proprietary and confidential information.
In addition, each executive is prohibited, during his employment at AppNet and
for two years after such employment ends if he resigns or is terminated for
cause or for one year after such employment ends, if he is terminated without
cause, from competing with AppNet, soliciting any of our employees or
interfering with any of our business relationships.

    The senior management agreements with Messrs. Tobaccowala, Harvey, McCalley,
Alexander and McManus provided for the sale of 175,439, 63,158, 110,175, 175,439
and 63,158 shares, respectively, or 587,369 shares in the aggregate, of our
common stock to these individuals at a per share price of $0.3007, for an
aggregate consideration of $176,607. In connection with these stock purchases,
each executive delivered a promissory note to AppNet for the full amount of the
purchase price, less the par value of the stock purchased. Each promissory note
is secured by a pledge of the purchased stock.

    Each senior management agreement restricts the transfer of the AppNet common
stock owned by the executive as of the date of the agreement until June 29,
2003, subject to specific exceptions, including:

    - sales in a registered public offering; and

    - sales, subject to volume limitations imposed by the senior management
      agreement, under Rule 144 under the Securities Act.

The registration agreement between AppNet and substantially all of its existing
stockholders dated June 29, 1998 states that each executive may request that his
shares of AppNet common stock be included in any registration statement filed by
AppNet:

    - to register common stock held by GTCR and Smart Technology; or

    - on its own behalf, other than in this offering.

    Each senior management agreement also provides that upon termination of the
executive's employment, AppNet may repurchase all or any portion of its common
stock owned by such executive

                                       59
<PAGE>
or his permitted transferees. A portion of the executive's common stock may be
repurchased at original cost, which is defined as the price originally paid by
the executive for such common stock; the remaining common stock may be
repurchased at the fair market value of such shares. If the executive's
employment is terminated for any reason before the first anniversary of his
senior management agreement, the amount of common stock which may be repurchased
at the original cost ranges from 75% to 100%, depending on the particular
executive. The portion of common stock to be repurchased at the original cost
decreases ratably each year until it reaches zero after the fourth anniversary
of the senior management agreement. If AppNet does not exercise its repurchase
right, GTCR, Smart Technology or Mr. Bajaj may repurchase the executive's AppNet
common stock upon the same terms and contribute them to AppNet in exchange for a
promissory note equal to the aggregate purchase price of such shares. This
repurchase right terminates upon:

    - the sale of capital stock with the voting power to elect a majority of the
      Board of Directors to persons or entities other than GTCR and Smart
      Technology, other than in a public offering; or

    - the sale of all or substantially all of our assets. We intend to amend the
      senior management agreements to terminate the right to repurchase an
      executive's shares of our common stock at their fair market value upon
      completion of this offering.

    Under the terms of the senior management agreement for Mr. McManus, whose
employment with us ended on December 31, 1998, we had the option to repurchase
some or all of his shares of our common stock upon the termination of his
employment. At the time of the termination of Mr. McManus' employment, we
entered into a stock purchase agreement with him which provided that we would
repurchase 89,474 shares of our common stock from him at purchase prices ranging
from $0.3007 to $0.7139 per share, and we would pay him $160,000 in severance
pay in accordance with his senior management agreement. The stock purchase
agreement with Mr. McManus gives us, GTCR, Smart Technology and Mr. Bajaj the
option to repurchase the remaining 29,825 shares of AppNet common stock owned by
Mr. McManus at fair market value until the earlier of September 30, 1999 or the
effective date of a registration statement filed by us in connection with a
public offering of our common stock. We have not determined whether we will
repurchase the remaining 29,825 shares.

STOCK INCENTIVE PLANS

    1999 STOCK INCENTIVE PLAN

    We intend to adopt the AppNet Systems, Inc. 1999 Stock Incentive Plan prior
to this offering. The 1999 Stock Incentive Plan will become effective upon its
adoption by the Board of Directors and ratification by our stockholders. The
purpose of the 1999 Stock Incentive Plan will be to strengthen AppNet by
providing an incentive to its employees, officers, consultants, directors and
advisors through the granting or awarding of incentive and nonqualified stock
options, stock appreciation and dividend equivalent rights, restricted stock,
performance units, performance shares, share awards and phantom stock awards,
thereby encouraging these individuals to devote their abilities and energies to
the success of AppNet.

    The 1999 Stock Incentive Plan will be administered by a compensation
committee, which will consist of non-employee directors. Under the 1999 Stock
Incentive Plan, the committee will have the authority to, among other things:

    - select the employees to whom stock options and other incentive awards will
      be granted;

    - determine the type, size and the terms and conditions of stock options and
      other incentive awards; and

    - establish the terms for treatment of stock options and other incentive
      awards upon a termination of employment.

                                       60
<PAGE>

    We will initially authorize 2,000,000 shares of common stock for issuance
under the 1999 Stock Incentive Plan for the grant of stock options and other
incentive awards to eligible individuals. The amount of common stock authorized
for issuance under the 1999 Stock Incentive Plan may be increased annually by
the compensation committee. The total amount of shares authorized under the Plan
may not exceed 10,000,000. The 1999 Stock Incentive Plan will terminate on the
day preceding the tenth anniversary of the date of its adoption by the Board of
Directors. The Board of Directors will be able to at any time and from time to
time amend or terminate the 1999 Stock Incentive Plan; provided, however, that,
to the extent necessary under applicable law, no such change will be effective
without the requisite approval of the stockholders. In addition, no such change
will alter or adversely impair any rights or obligations under any stock options
and other incentive awards previously granted, except with the written consent
of the grantee.


    1998 STOCK OPTION AND INCENTIVE PLAN

    We have adopted a stock incentive plan, the 1998 Stock Option and Incentive
Plan, and reserved 1,578,947 shares of our common stock for issuance in
connection with awards granted under such plan. Stock options and other
incentive awards under the 1998 Stock Option and Incentive Plan may be made in
the form of:

    - incentive stock options;

    - non-qualified stock options;

    - stock appreciation rights;

    - restricted stock; and

    - restricted stock units.

Stock options and other incentive awards may be granted to such persons,
including officers, directors and employees, that our Board of Directors or a
Board-appointed committee shall in its discretion select.


    As of May 26, 1999, options to purchase a total of 1,574,068 shares of our
common stock were outstanding under the 1998 Stock Option and Incentive Plan and
remain unexercised, 4,791 shares of our common stock have been issued upon the
exercise of options granted under the 1998 Stock Option and Incentive Plan and
options to purchase 154,936 shares of our common stock granted under the 1998
Stock Option and Incentive Plan are currently exercisable.


    The Board of Directors or a Board-appointed committee is authorized to
construe, interpret and implement the provisions of the 1998 Stock Option and
Incentive Plan, to select the persons to whom awards will be made, to determine
the terms and provisions of awards and, with the consent of the grantee, to
amend the terms of any outstanding award. The determinations of the Board of
Directors or a Board-appointed committee are made in its sole discretion and are
conclusive.

    The 1998 Stock Option and Incentive Plan has no termination date, however,
no incentive stock options may be granted under such plan on or after August 25,
2008. The Board of Directors may at any time and from time to time amend,
suspend or terminate the 1998 Stock Option and Incentive Plan; provided,
however, that, to the extent necessary under applicable law, no such change will
be effective without the requisite approval of the stockholders. In addition, no
such change will alter or adversely impair any rights or obligations under
awards previously granted, except with the written consent of the grantee. Upon
the adoption of our 1999 Stock Incentive Plan, no further awards will be made
under the 1998 Stock Option and Incentive Plan.

    CENTURY COMPUTING, INCORPORATED INCENTIVE STOCK OPTION PLAN

    In connection with our acquisition of Century Computing, we assumed its
Incentive Stock Option Plan and related award agreements with each grantee. Each
outstanding option to purchase the common stock of Century Computing was
converted into an incentive stock option to purchase our common stock based on a
conversion ratio. Originally, we reserved a total of 704,127 shares of our

                     CERTAIN RELATIONSHIPS AND TRANSACTIONS

GTCR AND SMART TECHNOLOGY PURCHASE AGREEMENT


    GTCR, Smart Technology and AppNet are parties to a purchase agreement, dated
as of June 29, 1998, as amended and supplemented which provided for the purchase
by GTCR and Smart Technology, L.L.C., an entity controlled by Mr. Bajaj's
spouse, of 11,326,228 and 232,916 shares of our common stock, respectively, at a
price of $0.3007 per share. At that time, GTCR and Smart Technology also agreed
from time to time to purchase up to an aggregate of 96,500 shares of Class A
Preferred Stock at a price of $1,000 per share in the future on the terms
described below. GTCR is required to purchase Class A Preferred Stock at the
request of AppNet's Board of Directors and the approval of GTCR to fund AppNet's
working capital requirements and acquisitions. Upon any such purchase by GTCR of
Class A Preferred Stock, Smart Technology is required to purchase Class A
Preferred Stock in an amount equal to approximately 2% of the amount of Class A
Preferred Stock GTCR purchases. Under these provisions, GTCR and Smart
Technology have purchased aggregate amounts of approximately 44,167 and 900
shares of Class A Preferred Stock, respectively, since June 29, 1998 for
aggregate purchase prices of approximately $44,167,000 and $900,000,
respectively. The purchase agreement with GTCR and Smart Technology currently
provides that as long as GTCR owns at least 15% of the securities purchased
under the purchase agreement, AppNet must obtain GTCR's prior written consent
before taking various actions including paying any dividends, other than
dividends on the Class A Preferred Stock, issuing any equity securities or debt
securities with equity features, acquiring businesses or merging or
consolidating with another entity. The parties intend to terminate the
provisions of the purchase agreement that require GTCR and Smart to purchase
Class A Preferred Stock and that require AppNet to obtain GTCR's consent before
taking various actions upon consummation of this offering. AppNet will still be
required to obtain GTCR's consent before amending its senior management
agreements with Messrs. Bajaj, Harvey, McManus and McCalley.


    In connection with AppNet's acquisition of Software Services Corporation and
the issuance of 11,576 shares of Class B Preferred Stock to the former
stockholders of that company, GTCR and Smart Technology transferred an aggregate
of 1,387,097 shares of AppNet common stock to us in exchange for an aggregate of
417.066 shares of our Class A Preferred Stock. In connection with a revolving
credit agreement between AppNet and BankBoston, N.A., GTCR and Smart Technology
sold an aggregate of 123,538 shares of our common stock and an aggregate of
approximately 362 shares of our Class A Preferred Stock to FSC Corp., an
affiliate of BankBoston, for an aggregate purchase price of $375,000. In
addition, the purchase agreement with GTCR and Smart Technology was amended in
August 1998 to decrease the commitment of GTCR and Smart Technology to purchase
96,500 shares of Class A Preferred Stock to 84,920 shares of Class A Preferred
Stock.

STOCKHOLDERS' AGREEMENT, REGISTRATION AGREEMENT AND SENIOR MANAGEMENT AGREEMENTS


    In connection with the purchase agreement with GTCR and Smart Technology,
AppNet, GTCR, Smart Technology and substantially all of AppNet's existing
stockholders entered into a stockholders' agreement, dated as of June 29, 1998
and a registration agreement, dated as of June 29, 1998. In addition, each
member of AppNet's senior management entered into a senior management agreement
with AppNet upon commencement of their employment with us. The stockholders'
agreement provides, among other things, that the Board of Directors will consist
of two representatives designated by GTCR, one representative designated by Mr.
Bajaj and three or more representatives chosen jointly by GTCR and Mr. Bajaj.
The stockholder's agreement also includes provisions restricting the
transferability of our common stock, giving AppNet a right of first refusal to
purchase a stockholder's common stock and giving stockholders a conditional
right to participate if GTCR and Smart Technology transfer their shares of
common stock. The stockholders' agreement will terminate upon the consummation
of this offering. Prior to consummation of the offering, AppNet and GTCR will
enter into an agreement that provides that as long as GTCR owns at least 15% of
the shares owned by it


                                       63
<PAGE>

immediately after the consummation of the Offering, AppNet will nominate at
least one GTCR designee to the Board.


    The registration agreement provides that the holders of a majority of our
common stock issued to GTCR and Smart Technology under the purchase agreement
with GTCR and Smart Technology may have the right to demand the filing of a
registration statement with the Securities and Exchange Commission to register
all or any portion of this common stock. Substantially all of the other current
stockholders of AppNet have the right to include all or any portion of their
AppNet common stock on registration statements filed by AppNet to register
shares of the common stock issued to GTCR and Smart Technology under the
purchase agreement with GTCR and Smart Technology; subject, however, to the
ability of the underwriters of any offering to limit the number of shares
included in such registration. Holders of the majority of our common stock
issued to GTCR and Smart Technology under the purchase agreement with GTCR and
Smart Technology may require AppNet to file, and pay the expenses in connection
with, up to four registration statements on Form S-1 and an unlimited number of
registration statements on Forms S-2 and S-3, if AppNet qualifies to use such
forms. If AppNet proposes to register securities for its own account, other than
in this offering. GTCR, Smart Technology and substantially all of AppNet's other
stockholders are entitled to notice of, and to include their shares in, such
registration; subject, however, to the ability of the underwriters of any
offering to limit the number of shares included in such registration. These
registration rights cover substantially all of the shares of our common stock
and will also cover any additional shares obtained by the parties to the
registration agreement. The existence and exercise of these registration rights
may make it more difficult for AppNet to arrange future financing and may have
an adverse effect on the market price of our common stock.

    In addition, our acquisition agreement with Arbor Intelligent Systems, Inc.
grants the former Arbor stockholders rights to have their shares of our common
stock included in any registration statement we file, other than in connection
with this offering; subject, however, to the ability of the underwriters of any
offering to limit the number of shares included in such registration.

    The senior management agreement with Mr. Bajaj provided for the sale of
1,251,228 shares of our common stock to Mr. Bajaj at a per share price of
$0.3007. The senior management agreement restricts the transferability of these
shares. AppNet, GTCR and Smart Technology have rights to repurchase these shares
upon the termination of Mr. Bajaj's employment.

    Mr. Bajaj pledged the 1,251,228 shares of common stock which he purchased in
accordance with the terms of his senior management agreement to AppNet to secure
a promissory note in the principal amount of $374,430 which Mr. Bajaj delivered
in partial payment for these shares. The senior management agreement between Mr.
Bajaj and AppNet gives AppNet the right, if it issues or sells common stock or
rights to acquire common stock, to its employees, to repurchase these shares,
whether held by Mr. Bajaj or his permitted transferees, to be issued or sold to
such employees at a price of $0.3007 per share. Upon the termination of Mr.
Bajaj's employment, AppNet has the right to repurchase all of these shares,
whether held by Mr. Bajaj or his transferees. AppNet's rights to repurchase
these shares terminate upon consummation of this offering. As of May 1, 1999,
AppNet had repurchased a total of 1,041,109 of these shares from Mr. Bajaj for
an aggregate purchase price of $313,035 reducing the principal amount of his
promissory note to $62,878.

PROFESSIONAL SERVICES AGREEMENT WITH FAIRFAX MANAGEMENT COMPANY II, L.L.C. AND
  FAIRFAX CONSULTING COMPANY, L.L.C.

    Stephen W. Ritterbush, a former vice chairman of our Board of Directors and
Bruce Gouldey, our former chief financial officer, are members of Fairfax
Consulting Company, L.L.C. They resigned their positions on June 29, 1998 in
connection with the GTCR and Smart Technology purchases of stock in AppNet under
the purchase agreement. We entered into a professional services agreement, dated
as of June 29, 1998, with Fairfax Management Company II, L.L.C. and Fairfax
Consulting Company, L.L.C.,

                                       64
<PAGE>
in which Fairfax Consulting Company agreed to provide to AppNet the services of
a financial and management consultant. In return for the consultant's services,
AppNet agreed to pay Fairfax Consulting Company a monthly retainer of $16,667 as
well as any fees for consulting services in excess of the monthly retainer. The
agreement also provided that if AppNet acquired a company which was introduced
to it by Fairfax Consulting Company, AppNet shall pay a finder's fee to Fairfax
Consulting Company equal to 1% of the purchase price for the acquired company.
We did not pay any finder's fees to Fairfax Consulting Company in 1998. In 1998,
AppNet paid approximately $336,000 in consulting fees to Fairfax Consulting
Company. The professional services agreement prohibited Fairfax Management
Company from owning, controlling, rendering services to or otherwise doing
business with one of our competitors while the agreement is in effect and for a
period of 18 months after it is terminated. We terminated the professional
services agreement with Fairfax Management Company and Fairfax Consulting
Company effective as of November 20, 1998.

    Fairfax Management Company purchased 2,052,632 shares of our common stock in
March 1998 for an aggregate purchase price of $5,850. AppNet repurchased
1,350,877 of these shares on June 29, 1998 in exchange for a convertible
promissory note in the principal amount of $406,175. The professional services
agreement with Fairfax Management Company and Fairfax Consulting Company
restricts the transfer of the 684,211 shares of our common stock that Fairfax
Management Company retained until June 29, 2003, except:

    - in a public offering;

    - under Rule 144 through a broker, dealer or market maker (other than under
      Rule 144(k)), in proportion to sales by GTCR and Smart Technology under
      Rule 144;

    - in the event of the sale of our capital stock with the voting power to
      elect a majority of the Board of Directors to persons or entities other
      than GTCR or Smart Technology, other than in a public offering; or

    - in the event of the sale of all or substantially all of our assets.

The principal balance of the convertible promissory note held by Fairfax
Management Company will be converted into shares of AppNet common stock upon
consummation of this offering at a conversion rate equal to 80% of the offering
price per share.

DAVIDSON AGREEMENT

    Thomas M. Davidson, one of our directors, and AppNet are parties to an
agreement dated as of June 29, 1998, under which Mr. Davidson received $350,000
in cash and 52,632 shares of common stock from AppNet as a finder's fee in
connection with the GTCR and Smart Technology investments in AppNet. The
Davidson agreement states that after GTCR and Smart Technology invest a total of
$15 million in shares of our common stock and Class A Preferred Stock, Mr.
Davidson shall receive additional finder's fees equal to 1% of all additional
purchases made by GTCR and Smart Technology of Class A Preferred Stock. AppNet's
obligation to pay this 1% commission to Mr. Davidson terminates when GTCR and
Smart Technology have invested an aggregate of $100 million in shares of AppNet
common stock and Class A Preferred Stock. As of March 31, 1999, GTCR and Smart
Technology have paid a total of $48.5 million in exchange for 11,559,144 shares
of our common stock and approximately 45,067 shares of Class A Preferred Stock,
and Mr. Davidson has earned a commission of approximately $685,000.

    The Davidson agreement also provided for the purchase by Mr. Davidson of
86,651 shares of our common stock at a price of $0.3007 per share. Under that
agreement, Mr. Davidson has a consulting arrangement with AppNet, which entitles
him to receive annual payments of $200,000. AppNet may terminate this consulting
arrangement upon thirty days' notice, although upon any termination prior to
June 29, 1999 for reasons other than for cause, we are required to pay to Mr.
Davidson $200,000 less

                                       65
<PAGE>
the aggregate amount of all consulting payments made prior to termination. On
May 17, 1999, AppNet gave Mr. Davidson thirty days' notice of the termination of
the consulting arrangement.

OTHER GTCR RELATIONSHIPS

    GTCR and AppNet are parties to a professional services agreement, dated as
of June 29, 1998, which entitles GTCR to $200,000 per year in exchange for
financial and management consulting services. This agreement also entitles GTCR
to receive an investment fee equal to 1% of the purchase price of the common
stock and Class A Preferred Stock it purchases from AppNet under the purchase
agreement with GTCR and Smart Technology. GTCR has earned approximately $475,000
in investment fees. The GTCR professional services agreement will terminate upon
the consummation of this offering.

    GTCR has guaranteed a portion of our outstanding indebtedness. We anticipate
that this guarantee will terminate upon the repayment of our credit facilities
with the proceeds of this offering and the termination of the guaranteed portion
of our credit facilities.

OTHER SMART TECHNOLOGY RELATIONSHIPS

    During 1998, Smart Technology loaned approximately $1.1 million to AppNet.
On May 31, 1998, AppNet issued a warrant to purchase 35,088 shares of its common
stock for an aggregate purchase price of $50,000 to Smart Technology as
consideration, in part, for this loan. On June 29, 1998, a portion of the $1.1
million loan equal to the purchase price of the common stock Smart Technology
acquired from AppNet under the purchase agreement with GTCR and Smart Technology
was canceled, and AppNet issued a new promissory note in the principal amount of
$903,567 to Smart Technology. This note bears interest at the rate of 12% per
annum. The principal amount of this note is reduced from time to time by an
amount equal to the purchase price of any Class A Preferred Stock purchased by
Smart Technology under the purchase agreement with GTCR and Smart Technology.
The amount outstanding under this note has been reduced to $3,300 as of May 1,
1999 and will be repaid with the proceeds of this offering. Also on June 29,
1998, in accordance with the purchase agreement with GTCR and Smart Technology,
the original warrant issued to Smart Technology was canceled and AppNet issued a
new warrant to Smart Technology to purchase 70,175 shares of AppNet common stock
for an exercise price of $0.3007 per share.

    In 1998, we paid Smart Technology approximately $25,000 in exchange for
consulting services.

CROSS SENIOR MANAGEMENT AGREEMENT

    We entered into a senior management agreement with John Cross, one of our
directors, in March 1999, which provides for his employment as an Executive Vice
President until he resigns, is disabled, as determined by the Board of Directors
in its good faith judgment, dies or is terminated by the Board of Directors for
any reason. Mr. Cross is entitled to receive a salary of $300,000 per year,
subject to increases as determined by the Board of Directors based upon AppNet's
achievement of budgetary and other objectives set by the Board of Directors. Mr.
Cross is eligible to receive a bonus of up to 50% of his salary based upon
AppNet's achievement of budgetary and other objectives set by the Board of
Directors.

    If Mr. Cross' employment is terminated without cause, he is entitled to
receive his annual salary and life, medical and disability insurance benefits
for one year. Cause is defined generally as:

    - commission of a felony or crime involving moral turpitude;

    - fraud, gross negligence or willful misconduct with respect to AppNet;

    - substantial and repeated failure to perform duties; or

    - breach of the confidentiality or noncompete provisions of the senior
      management agreement.

                                       66
<PAGE>
    The senior management agreement contains provisions requiring Mr. Cross to
protect the confidentiality of our proprietary and confidential information. In
addition, Mr. Cross is prohibited, during his employment at AppNet and for two
years after his employment ends if he resigns or is terminated for cause or for
one year after his employment ends if he is terminated without cause, from
competing with AppNet, soliciting any of our employees or interfering with any
of our business relationships.

    In 1999, John Cross also received options to purchase 337,776 shares of
AppNet common stock at an exercise price of $12.825 per share. The fair value of
the common stock underlying these options as of the date of grant was $14.25 per
share.

      prospectus; and



    - 121 shares of Class A Preferred Stock have been reserved for issuance in
      connection with a warrant issued to Silicon Valley Bank.


COMMON STOCK

    Each share of our common stock is identical in all respects and entitles the
holder thereof to the same rights and privileges enjoyed by all other holders of
shares of common stock, and subjects them to the same qualifications,
limitations and restrictions to which all such other holders are subject.

    VOTING RIGHTS.  Holders of our common stock are entitled to one vote per
share on all matters to be voted on by AppNet's stockholders and may act by
written consent if the consent is signed by the holders of common stock having
at least the minimum votes necessary to authorize or take such action at
meetings. Holders of common stock do not have cumulative rights, so that holders
of a plurality of the shares of common stock present at a meeting at which a
quorum is present are able to elect all of AppNet's directors eligible for
election in a given year. The holders of a majority of the voting power of the
issued and outstanding common stock constitutes a quorum. We intend to amend our
certificate of incorporation to provide that a vote of two-thirds of the holders
of our issued and outstanding common stock will be required to remove a director
or amend our bylaws.

    DIVIDENDS.  Holders of our common stock are entitled to receive ratably such
dividends, if any, as are declared by AppNet's Board of Directors out of funds
legally available for the declaration of dividends, subject to the preferential
rights of any holder of preferred stock that may from time to time

                                       69
<PAGE>
be outstanding. The terms of our credit facilities restrict AppNet's ability to
pay dividends on the common stock.

    LIQUIDATION.  Upon the liquidation, dissolution or winding up of AppNet, the
holders of our common stock are entitled to share pro rata in the distribution
of all of AppNet's assets available for distribution after satisfaction of all
of AppNet's liabilities and the payment of the liquidation preference of any
preferred stock that may be outstanding.

    OTHER PROVISIONS.  The holders of our common stock have no preemptive or
other subscription rights to purchase common stock, and there are no redemptive
rights or sinking fund provisions. The holders of our common stock are not
liable for any calls or assessments.

    REGISTRATION RIGHTS.  AppNet is a party to a registration agreement, dated
as of June 29, 1998, to which substantially all current stockholders of AppNet
are party, which gives the holders of a majority of the common stock issued to
GTCR and Smart Technology under the purchase agreement with GTCR and Smart
Technology a conditional right to demand registration of all or any portion this
common stock. Substantially all of the other current stockholders of AppNet have
the right to include all or any portion of their AppNet common stock on
registration statements filed by AppNet to register the common stock issued to
GTCR and Smart Technology under the purchase agreement with GTCR and Smart
Technology. Subject to various conditions, substantially all of the current
stockholders of AppNet have the right to include all or any portion of their
AppNet common stock on registration statements that we file on our own behalf,
other than in connection with this offering. These rights cover substantially
all of the shares of our common stock and will also cover any additional shares
obtained by the parties to the registration agreement.

    In addition, our acquisition agreement with Arbor gave the former
stockholders of Arbor rights to have their shares of our common stock included
in any registration statement we file, other than in connection with this
offering.

PREFERRED STOCK

    We intend to amend AppNet's certificate of incorporation, a copy of which is
filed as an exhibit to the registration statement of which this prospectus is a
part, to authorize AppNet's Board of Directors to issue preferred stock in one
or more series and to establish the number of shares to be included in each such
series and to fix the designations, powers, preferences and rights of the shares
of each such series and any qualifications, limitations or restrictions of each
such series. Because the Board of Directors will have the power to establish the
preferences and rights of the shares of any such series of preferred stock, it
may afford the holders of any such series of preferred stock preferences, powers
and rights, including voting rights, senior to the rights of the holders of
common stock. The issuance of preferred stock may have the effect of delaying,
deferring or preventing a change in control of AppNet.

    The Board of Directors has established a class of preferred stock designated
Class A Preferred Stock consisting of 96,621 authorized shares, par value $0.01
per share, and a class of preferred stock designated Class B Preferred Stock
consisting of 20,000 authorized shares, par value $0.01 per share. The Class B
Preferred Stock ranks PARI PASSU with the Class A Preferred Stock.

    We intend to use the proceeds from this offering to redeem at least 1,641
shares of Class A Preferred Stock and 418 shares of Class B Preferred Stock. All
remaining outstanding shares of Class A and Class B Preferred Stock that are not
redeemed with proceeds from this offering will be exchanged for shares of our
common stock. These shares will be canceled and will not be reissued, sold or
transferred. The preferred stock has the dividend, redemption, liquidation and
other rights described below. The exchange ratio shall be determined by dividing
the liquidation value of each share of preferred stock plus accrued and unpaid
dividends by the initial public offering price per share of common stock.

                                       70
<PAGE>
    VOTING RIGHTS.  Neither Class A nor Class B Preferred Stock is entitled to
any voting rights, other than those granted by the Delaware General Corporation
Law, provided that each holder of Class A and Class B Preferred Stock is
entitled to notice of all stockholders meetings at the same time and in the same
manner to which all stockholders entitled to vote at such meetings are entitled.

    DIVIDEND RIGHTS.  When and as declared by AppNet's Board of Directors and to
the extent permitted under the Delaware General Corporation Law, holders of
Class A and Class B Preferred Stock are entitled to preferential cash dividends.
Dividends on each share of Class A and Class B Preferred Stock accrue on a daily
basis at the rate of 6% per annum on the liquidation value per share of $1,000,
plus all accumulated and unpaid dividends from and including the date of
issuance of such share to and including the first to occur of:

    - the date on which the liquidation value of such share, plus all accrued
      and unpaid dividends, is paid to the holder in connection with the
      liquidation of AppNet or the redemption of such share by AppNet; and

    - the date on which such share is otherwise acquired by AppNet.

    Dividends on the Class A and Class B Preferred Stock accrue whether or not
they have been declared and whether or not there are profits, surplus or other
funds legally available for the payment of dividends. To the extent dividends
are not paid on March 31, June 30, September 30, and December 31 of each year
for Class A Preferred Stock, and on September 30 of each year for Class B
Preferred Stock, the accrued dividends will accumulate on such dates. All
accrued and unpaid dividends will be fully paid or declared with funds
irrevocably set apart for payment before we are entitled to pay any dividends,
distributions, redemptions or other payments with respect to any stock of AppNet
other than Class A and Class B Preferred Stock.

    DISTRIBUTION OF PARTIAL DIVIDEND PAYMENTS.  Unless otherwise provided, if at
any time AppNet pays less than the total amount of accrued dividends with
respect to the Class A or Class B Preferred Stock, the payment will be
distributed pro rata among the holders of the class of preferred stock, based
upon the aggregate accrued but unpaid dividends on the shares held by each such
holder.

    LIQUIDATION.  Upon any liquidation, dissolution or winding up of AppNet,
voluntary or involuntary, each holder of Class A or Class B Preferred Stock will
be entitled to an amount in cash equal to the aggregate liquidation value of all
shares held by the holder, plus all accrued and unpaid dividends thereon, before
any distribution or payment is made upon any securities that are junior to the
Class A and Class B Preferred Stock. The holders of Class A and Class B
Preferred Stock will not be entitled to receive any further payment. Prior to
the time of any liquidation, dissolution or winding up of AppNet, to the extent
permitted by applicable law, AppNet will declare for payment all accrued and
unpaid dividends with respect to the Class A and Class B Preferred Stock.

    PRIORITY OF PREFERRED STOCK.  So long as any Class A or Class B Preferred
Stock remains outstanding, without the prior written consent of the holders of a
majority of the outstanding shares of such preferred stock, AppNet will not be
entitled, nor will it permit any subsidiary, to redeem, purchase or otherwise
acquire directly or indirectly any securities that are junior to the Class A and
Class B Preferred Stock, nor is AppNet entitled directly or indirectly to pay or
declare any dividend or make any distribution upon any securities that are
junior to the Class A and Class B Preferred Stock. However, even if any such
shares of Class A or Class B Preferred Stock are outstanding, AppNet is entitled
to purchase shares of its common stock under an arrangement approved by the
Board of Directors from present or former employees of AppNet or its
subsidiaries.

                                       71
<PAGE>
    REDEMPTION RIGHTS APPLICABLE ONLY TO CLASS A PREFERRED STOCK

        OPTIONAL REDEMPTIONS BY APPNET. At any time and from time to time,
    AppNet may redeem all or any portion of any outstanding shares of Class A
    Preferred Stock. Upon any such redemption, AppNet will pay a price per share
    equal to the liquidation value thereof, plus all accrued and unpaid
    dividends thereon. No redemption may be made for less than 1,000 shares or
    such lesser number of shares then outstanding.

        REDEMPTIONS AFTER PUBLIC OFFERINGS. At the written request of the
    holders of a majority of the shares of Class A Preferred Stock then
    outstanding, AppNet will apply the net cash proceeds from any public
    offering of AppNet common stock under an effective registration statement
    under the Securities Act to redeem shares of Class A Preferred Stock at the
    liquidation value of $1,000 per share, plus all accrued and unpaid dividends
    thereon. Such redemption must take place not more than five days after
    AppNet receives such public offering proceeds.

        REDEMPTION PAYMENTS. On any date on which Class A Preferred Stock is to
    be redeemed, if AppNet's funds that are legally available for redemption are
    insufficient to redeem the total number of shares to be redeemed, those
    funds which are legally available will be used to redeem the maximum
    possible number of shares pro rata among the holders of the shares to be
    redeemed. At any time thereafter when additional funds are legally available
    for redemption of shares by AppNet, such funds will be immediately used to
    redeem the balance of the shares which AppNet is obligated to redeem.

        SPECIAL REDEMPTIONS. If either (a) a change in ownership, which is
    defined as the transfer of more than 50% of the outstanding common stock to
    a person or group of persons other than any stockholder of AppNet as of June
    29, 1998, has occurred or AppNet obtains knowledge that a change in
    ownership is proposed or (b) a fundamental change, which is defined as the
    transfer of more than 50% of AppNet's assets or mergers or consolidations
    involving AppNet where Appnet is not the surviving party, is proposed to
    occur, then the holder or holders of a majority of the shares of Class A
    Preferred Stock then outstanding may require AppNet to redeem all or any
    portion of the Class A Preferred Stock owned by such holders at a price per
    share equal to the liquidation value thereof, plus all accrued and unpaid
    dividends thereon, by giving written notice of such election. AppNet must
    give all holders of Class A Preferred Stock prompt notice of any proposed
    change in ownership or fundamental change and notice of any election to
    redeem shares because of such changes.

    REDEMPTION AND CONVERSION RIGHTS APPLICABLE ONLY TO CLASS B PREFERRED STOCK.

        AppNet has the contractual ability to redeem or convert all outstanding
    shares of Class B Preferred Stock upon an initial public offering.
    Contractual provisions provide that, upon a sale of AppNet, all outstanding
    shares of Class B Preferred Stock will be redeemable at a price per share
    equal to the liquidation value or the holders will receive the same
    consideration per share as the holders of the Class A Preferred Stock.

ANTI-TAKEOVER EFFECTS OF APPNET'S CERTIFICATE OF INCORPORATION AND BYLAWS AND
  PROVISIONS OF DELAWARE LAW

    AppNet's certificate of incorporation and bylaws and Section 203 of the
Delaware General Corporation Law contain provisions that may make the
acquisition of control of AppNet by means of a tender offer, open market
purchase, proxy fight or otherwise, more difficult.

    BUSINESS COMBINATIONS.  We intend to amend our certificate of incorporation
to provide that we will be subject to Section 203 of the Delaware General
Corporation Law. In general, subject to specific exceptions, Section 203 of the
Delaware General Corporation Law prohibits a publicly held Delaware

                                       72
<PAGE>
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder, unless:

    - upon consummation of the transaction, the interested stockholder owned 85%
      of the voting stock of the corporation outstanding at the time the
      transaction commenced, excluding for purposes of determining the number of
      shares outstanding those shares owned by persons who are directors and
      also officers and employee stock plans in which employee participants do
      not have the right to determine confidentially whether shares held subject
      to the plan will be tendered in a tender or exchange offer;

    - the business combination is, or the transaction in which such person
      became an interested stockholder was, approved by the board of directors
      of the corporation before the stockholder became an interested
      stockholder; or

    - the business combination is approved by the board of directors of the
      corporation and authorized at an annual or special meeting of the
      corporation's stockholders by the affirmative vote of at least 66 2/3% of
      the outstanding voting stock which is not owned by the interested
      stockholder.

    For purposes of Section 203, a "business combination" includes mergers,
asset sales and other transactions resulting in a financial benefit to the
interested stockholder; an "interested stockholder" is a person who, together
with affiliates and associates, owns, or, in the case of affiliates and
associates of the issuer, did own within the last three years, 15% or more of
the corporation's voting stock. The restrictions set forth in Section 203 will
not apply to a business combination with an interested stockholder who became an
interested stockholder at a time when the restrictions of Section 203 did not
apply to AppNet.

    STOCKHOLDER NOMINATIONS AND PROPOSALS.  We intend to amend our bylaws to
provide that stockholders must follow an advance notification procedure for
stockholder nominations of candidates for the Board of Directors and for other
stockholder business to be conducted at an annual meeting. For business a
stockholder wishes to bring before an annual meeting of stockholders, the
stockholder must deliver notice to AppNet not less than 60 days nor more than 90
days prior to the date of the anniversary of the previous year's annual meeting.
For nominations of persons for election to our Board of Directors at an annual
meeting, a stockholder must deliver notice to AppNet not less than 90 days prior
to the date of the anniversary of the previous year's annual meeting unless the
annual meeting is delayed, in which case the stockholder must deliver the notice
not less than 90 days prior to such meeting nor more than 10 days after we
mailed notice of such meeting or public disclosure of the annual meeting was
made. These advance notification provisions in our bylaws could preclude the
conduct of business at a meeting or a nomination for the election of directors
if the proper procedures are not followed. Such provisions could operate to
delay, defer or prevent a change in control of AppNet.


    AUTHORIZED AND UNISSUED PREFERRED STOCK.  Upon consummation of this
offering, there will be 4,883,379 authorized and unissued shares of preferred
stock. We intend to amend our certificate of incorporation to authorize the
Board of Directors to issue one or more series of preferred stock and to
establish the designations, powers, preferences and rights of each series of
preferred stock. The existence of authorized and unissued preferred stock may
enable the Board of Directors to render more difficult or to discourage an
attempt to obtain control of AppNet by means of a merger, tender offer, proxy
contest or otherwise. For example, if in the due exercise of its fiduciary
obligations, the Board of Directors were to determine that a takeover proposal
is not in AppNet's best interests, the Board of Directors could cause shares of
preferred stock to be issued without stockholder approval in one or more private
offerings or other transactions that might dilute the voting or other rights of
the proposed acquiror or insurgent stockholder or stockholder group or create a
substantial voting block in


                                       73
<PAGE>
institutional or other hands that might undertake to support the position of the
incumbent Board of Directors.

    ABSENCE OF CUMULATIVE VOTING.  Our certificate of incorporation does not
include a provision for cumulative voting in the election of directors. Under
cumulative voting, a minority stockholder holding a sufficient number of shares
may be able to ensure the election of one or more directors. The absence of
cumulative voting may have the effect of limiting the ability of minority
stockholders to effect changes in our Board of Directors and, as a result, may
operate to delay, defer or prevent a change in control of AppNet.

    REMOVAL OF DIRECTORS; VACANCIES.  We intend to amend our certificate of
incorporation to state that, subject to the rights of the holders of our
preferred stock, directors may be removed at any time by two-thirds stockholder
vote. In addition, a majority of the directors then in office will be able to
fill board vacancies and newly created directorships resulting from any increase
in the size of our Board of Directors. This is true even if those directors do
not constitute a quorum or if only one director is left in office. These
provisions could prevent stockholders, including parties who want to take over
or acquire AppNet, from removing incumbent directors and filling the resulting
vacancies with their own nominee.

    SPECIAL MEETINGS OF STOCKHOLDERS.  We intend to amend our bylaws to provide
that special meetings of AppNet's stockholders may be called only by the Board
of Directors of AppNet. This provision may render it more difficult for
stockholders to take action opposed by the Board of Directors.

INDEMNIFICATION AND LIMITATION OF LIABILITY

    AppNet's bylaws provide that AppNet will indemnify each of its directors,
officers, employees and agents to the fullest extent permitted by law. The
certificate of incorporation limits the liability of AppNet's directors and
stockholders to AppNet for monetary damages. The certificate of incorporation
also provides that AppNet may purchase insurance on behalf of its directors,
officers, employees and agents against liabilities they may incur in such
capacity, whether or not AppNet would have the power to indemnify against such
liabilities.

TRANSFER AGENT AND REGISTRAR


    The transfer agent and registrar for our common stock is BankBoston, N.A.


                                       74
<PAGE>
                        SHARES ELIGIBLE FOR FUTURE SALE


    Upon consummation of this offering, 30,441,434 shares of our common stock
will be outstanding, 31,341,434 shares if the over-allotment option is exercised
in full. Of these shares, the 6,900,000 shares of common stock sold in this
offering will be freely tradable without restriction or further registration
under the Act, unless held by an "affiliate" of AppNet. An affiliate is defined
under Rule 144 as a person that controls, is controlled by or is under common
control with AppNet. All of the shares of our common stock outstanding prior to
the offering are "restricted securities," as such term is defined under Rule
144. These shares are restricted securities because they were issued in private
transactions not involving a public offering and may not be sold in the absence
of registration other than in accordance with Rule 144 or Rule 701 promulgated
under the Securities Act or another exemption from registration. This prospectus
may not be used in connection with any resale of shares of our common stock
acquired in the offering by affiliates of AppNet.


    Each of AppNet, our directors, our officers, most of the former owners of
all of the businesses we acquired, GTCR and Smart Technology have agreed not to
offer or transfer, or file with the Securities and Exchange Commission a
registration statement under the Securities Act relating to, any shares of our
common stock or securities convertible into or exchangeable or exercisable for
any shares of our common stock without the prior written consent of Credit
Suisse First Boston Corporation for a period of 180 days after the date of this
prospectus. The restrictions set forth in the previous sentence do not apply to
grants of employee stock options under the terms of AppNet's stock incentive
plans in effect on the date of this prospectus, issuances of securities as a
result of the exercise of such options outstanding on the date of this
prospectus and issuances of securities as a result of the conversion of any
convertible instruments outstanding on the date of this prospectus.

    In general, under Rule 144 as currently in effect, if a minimum of one year
has elapsed since the later of the date of acquisition of the restricted
securities from the issuer or from an affiliate of the issuer, a person, or
persons whose shares of common stock are aggregated, including persons who may
be deemed affiliates of AppNet, would be entitled to sell within any three-month
period a number of shares of AppNet common stock that does not exceed the
greater of


    (1) one percent of the then-outstanding shares of AppNet common stock, which
       equals approximately 304,414 shares immediately after this offering, or


    (2) the average weekly trading volume during the four calendar weeks
       preceding the date on which notice of the sale is filed with the
       Securities and Exchange Commission.

    Sales under Rule 144 are also subject to restrictions as to the manner of
sale, notice requirements and the availability of current public information
about AppNet. In addition, under Rule 144(k), if a period of at least two years
has elapsed since the later of the date restricted securities were acquired from
AppNet or the date they were acquired from an affiliate of AppNet, a stockholder
who is not an affiliate of AppNet at the time of sale and who has not been an
affiliate of AppNet for at least three months prior to the sale would be
entitled to sell shares of our common stock in the public market immediately
without compliance with the requirements under Rule 144 set forth above. If
shares are transferred during this period, the holding period requirement may be
satisfied by including the time period during which such shares were previously
held. The foregoing summary of Rule 144 is not intended to be a complete
description thereof.

    In addition, any of our employees, directors, officers or consultants who
acquired shares under a written compensatory plan or contract may be entitled to
rely on the resale provisions of Rule 701 of the Securities Act without having
to comply with the public information, holding period, volume limitation or
notice provisions of Rule 144, and affiliates of AppNet may be entitled to sell
their Rule 701 shares without having to comply with the holding period
restrictions of Rule 144, in each

                                       75
<PAGE>
case, commencing 90 days after the date of this prospectus, although the
contractual limitations will continue through the 180th day following the date
of this prospectus.

    In addition to the restrictions on transfer described above, our executives
with whom we have entered into senior management agreements are subject to
restrictions on the transfer of shares of our common stock owned by them as of
the date they entered into the senior management agreement.


    Immediately following the offering, none of the 20,068,098 "restricted
securities" will be available for immediate sale in the public market under Rule
144. Beginning 90 days after the date of this prospectus, and without
consideration of the contractual restrictions described above, 1,741,831 shares
either issued under our stock incentive plans or compensation contracts or
acquired upon the exercise of options issued under our stock incentive plans
will be outstanding and eligible for sale in reliance upon Rule 701. Additional
shares may be available if options are exercised in the 90-day period following
the date of this prospectus. Shares of our common stock issued in reliance on
Rule 701 may be resold by holders who are not affiliates of AppNet under Rule
144 without compliance with the holding period, amount and notice limitations
and by holders who are affiliates of AppNet under Rule 144 without compliance
with the holding period limitation.



    Following this offering, we intend to file a registration statement on Form
S-8 under the Securities Act to register 5,383,914 shares of our common stock
reserved for issuance or previously issued under our employee benefit plans and
compensation contracts. Shares of our common stock issued under our stock
incentive plans generally will be available for sale in the open market by
holders who are not affiliates of AppNet and, subject to the volume and other
applicable limitations of Rule 144, by holders who are affiliates of AppNet,
unless such shares are subject to vesting restrictions or the contractual
restrictions described above.


    We are a party to a registration agreement, dated as of June 29, 1998, which
gives the holders of a majority of the common stock issued to GTCR and Smart
Technology under the purchase agreement with GTCR and Smart Technology a
conditional right to demand registration of all or any portion of this common
stock. Substantially all of our other current stockholders have the right to
include all or any portion of their AppNet common stock on registration
statements we file to register the common stock issued to GTCR and Smart
Technology under the purchase agreement with GTCR and Smart Technology. Subject
to specific conditions, substantially all of our current stockholders have the
right to include all or any portion of their AppNet common stock on registration
statements we file on our own behalf, other than in an initial public offering.
These rights cover substantially all of the shares of our common stock and will
also cover any shares obtained by parties to the registration agreement.
Registration of these shares of our common stock would permit the sale of these
shares without regard to the restrictions of Rule 144. In addition, our
acquisition agreement with Arbor gave the former stockholders of Arbor rights to
have their shares of our common stock included in any registration statement,
other than in connection with this offering.

    Prior to this offering, there has been no public market for our common
stock. No information is currently available, and we cannot predict the timing
or amount of future sales of shares, or the effect, if any, that future sales of
shares, or the availability of shares for future sale, will have on the market
price of our common stock prevailing from time to time. Sales of substantial
amounts of our common stock, including shares issuable upon the exercise of
stock options, in the public market after the lapse of the restrictions
described above, or the perception that such sales may occur, could materially
and adversely affect the prevailing market price for our common stock and our
ability to raise equity capital in the future.

              U.S. FEDERAL TAX CONSIDERATIONS FOR NON-U.S. HOLDERS

    The following is a general discussion of the principal United States federal
income and estate tax consequences of the ownership and disposition of common
stock by a non-U.S. holder. As used in this prospectus, a non-U.S. holder is
defined as a holder that for United States federal income tax purposes is an
individual or entity other than:

    - a citizen or individual resident of the United States;

    - a corporation or partnership created or organized in or under the laws of
      the United States or of any political subdivision thereof, other than a
      partnership treated as foreign under U.S. Treasury regulations;

    - an estate the income of which is subject to U.S. federal income taxation
      regardless of its source; or

    - a trust if a U.S. court is able to exercise primary supervision over the
      administration of the trust and one or more U.S. persons have the
      authority to control all substantial decisions of the trust.

    An individual may, subject to a number of exceptions, be deemed to be a
resident alien, as opposed to a nonresident alien, by virtue of being present in
the United States for at least 31 days in the calendar year and for an aggregate
of at least 183 days during a three-year period ending in the current calendar
year, counting for such purposes all of the days present in the current year,
one-third of the days present in the immediately preceding year and one-sixth of
the days present in the second preceding year. Resident aliens are subject to
U.S. federal tax as if they were U.S. citizens.

    This discussion does not address all aspects of United States federal income
and estate taxes that may be relevant to non-U.S. holders in light of their
personal circumstances, including the fact that in the case of a non-U.S. holder
that is a partnership, the U.S. tax consequences of holding and disposing of
shares of common stock may be affected by determinations made at the partner
level, or that may be relevant to non-U.S. holders which may be subject to
special treatment under United States federal income tax laws such as insurance
companies, tax-exempt organizations, financial institutions, dealers in
securities and holders of securities held as part of a "straddle," "hedge" or
"conversion transaction." This discussion also does not address U.S. state or
local or foreign tax consequences. Furthermore, this discussion is based on
provisions of the Internal Revenue Code of 1986, as amended, existing and
proposed regulations promulgated thereunder and administrative and judicial
interpretations thereof, all as of the date hereof, and all of which are subject
to change, possibly with retroactive effect. The following summary is included
herein for general information. ACCORDINGLY, PROSPECTIVE INVESTORS ARE URGED TO
CONSULT THEIR TAX ADVISERS REGARDING THE UNITED STATES FEDERAL, STATE, LOCAL AND
NON-U.S. INCOME AND OTHER TAX CONSEQUENCES OF ACQUIRING, HOLDING AND DISPOSING
OF SHARES OF COMMON STOCK.

DIVIDENDS

    We do not anticipate paying cash dividends on our common stock in the
foreseeable future. In the event, however, that dividends are paid on shares of
our common stock, dividends paid to a non-U.S. holder of common stock generally
will be subject to withholding of United States federal income tax at a 30%
rate, or such lower rate as may be provided by an income tax treaty between the
United States and a foreign country if the non-U.S. holder is treated as a
resident of such foreign country within the meaning of the applicable treaty.
Non-U.S. holders should consult their tax advisors regarding their entitlement
to benefits under a relevant income tax treaty.

    Dividends that are effectively connected with a non-U.S. holder's conduct of
a trade or business in the United States or, if an income tax treaty applies,
attributable to a permanent establishment in the United States, are generally
subject to U.S. federal income tax on a net income basis at regular graduated
rates, but are not generally subject to the 30% withholding tax if the non-U.S.
holder files

                                       77
<PAGE>
the appropriate U.S. Internal Revenue Service form with the payor, which form
under U.S. Treasury regulations generally requires the non-U.S. holder to
provide a U.S. taxpayer identification number. Any such U.S. trade or business
income received by a non-U.S. holder that is a corporation may also be subject
to an additional "branch profits tax" at a 30% rate or such lower rate as may be
specified by an applicable income tax treaty.

    Under currently applicable U.S. Treasury regulations, dividends paid to an
address in a foreign country are presumed, absent actual knowledge to the
contrary, to be paid to a resident of such country for purposes of the
withholding discussed above and for purposes of determining the applicability of
a tax treaty rate. Under U.S. Treasury regulations generally effective for
payments made after December 31, 2000, however, a non-U.S. holder of our common
stock who wishes to claim the benefit of an applicable treaty rate generally
will be required to satisfy applicable certification and other requirements. In
addition, under these regulations, in the case of our common stock held by a
foreign partnership, the certification requirement will generally be applied to
the partners of the partnership and the partnership will be required to provide
specified information, including a United States taxpayer identification number.
The regulations generally effective for payments made after December 31, 2000,
also provide look-through rules for tiered partnerships. Further, the Internal
Revenue Service intends to issue regulations under which a foreign trustee or
foreign executor of a U.S. or foreign trust or estate, depending on the
circumstances, will be required to furnish the appropriate withholding
certificate on behalf of the beneficiaries, grantor trust or estate, as the case
may be.

    A non-U.S. holder of our common stock that is eligible for a reduced rate of
U.S. withholding tax under an income tax treaty may obtain a refund of any
excess amounts withheld by filing an appropriate claim for a refund with the
Internal Revenue Service.

    The U.S. Treasury regulations generally effective for payments made after
December 31, 2000 also provide special rules for dividend payments made to
foreign intermediaries, U.S. or foreign wholly owned entities that are
disregarded for U.S. federal income tax purposes and entities that are treated
as fiscally transparent in the United States, the applicable income tax treaty
jurisdiction, or both. In addition, recently enacted legislation, effective
August 5, 1997, denies income tax treaty benefits to foreigners receiving income
derived through a partnership, or otherwise fiscally transparent entity, in
certain circumstances. Prospective investors should consult with their own tax
advisers concerning the effect, if any, of these new Treasury regulations and
this recent legislation on an investment in our common stock.

GAIN ON DISPOSITION OF COMMON STOCK

    A non-U.S. holder generally will not be subject to U.S. federal income tax
in respect of gain recognized on a disposition of our common stock unless:

    - the gain is U.S. trade or business income, in which case, the branch
      profits tax described above may also apply to a corporate non-U.S. holder;

    - the non-U.S. holder is an individual who holds our common stock as a
      capital asset within the meaning of Section 1221 of the Internal Revenue
      Code, is present in the United States for 183 or more days in the taxable
      year of the disposition and meets other requirements;

    - the non-U.S. holder is subject to tax under the provisions of the U.S. tax
      law applicable to certain United States expatriates; or

    - AppNet is or has been a "U.S. real property holding corporation" for
      federal income tax purposes at any time during the shorter of the
      five-year period preceding such disposition or the period that the
      non-U.S. holder held our common stock.

                                       78
<PAGE>
Generally, a corporation is a "U.S. real property holding corporation" if the
fair market value of its "U.S. real property interests" equals or exceeds 50% of
the sum of the fair market value of its worldwide real property interests plus
its other assets used or held for use in a trade or business. We believe that we
have not been, are not currently, and do not anticipate becoming, a "U.S. real
property holding corporation" for U.S. federal income tax purposes. The tax with
respect to stock in a "U.S. real property holding corporation" does not apply to
a non-U.S. holder whose holdings, direct and indirect, at all times during the
applicable period, constituted 5% or less of our common stock, provided that our
common stock was regularly traded on an established securities market. If we
were, or were to become, a U.S. real property holding corporation, we believe
that our common stock would be treated as "regularly traded."

    If a non-U.S. holder who is an individual is subject to tax on gain which is
U.S. trade or business income, such individual generally will be taxed on the
net gain derived from a sale of common stock under regular graduated United
States federal income tax rates. If an individual non-U.S. holder is subject to
tax because such individual holds our common stock as a capital asset, is
present in the United States for 183 or more days in the taxable year of the
disposition and meets other requirements, such individual generally will be
subject to a flat 30% tax on the gain derived from a sale, which may be offset
by United States capital losses, notwithstanding the fact that such individual
is not considered a resident alien of the United States. Thus, individual
non-U.S. holders who have spent (or expect to spend) more than a DE MINIMIS
period of time in the United States in the taxable year in which they
contemplate a sale of common stock are urged to consult their tax advisers prior
to the sale concerning the U.S. tax consequences of such sale.

    If a non-U.S. holder that is a foreign corporation is subject to tax on gain
which is U.S. trade or business income, it generally will be taxed on its net
gain under regular graduated United States federal income tax rates and, in
addition, will be subject to the branch profits tax equal to 30% of its
"effectively connected earnings and profits," within the meaning of the Internal
Revenue Code for the taxable year, as adjusted for specific items, unless it
qualifies for a lower rate under an applicable tax treaty.

FEDERAL ESTATE TAX

    Common stock owned or treated as owned by an individual who is neither a
United States citizen nor a United States resident, as defined for United States
federal estate tax purposes, at the time of death will be included in the
individual's gross estate for United States federal estate tax purposes, unless
an applicable estate tax or other treaty provides otherwise and, therefore, may
be subject to United States federal estate tax.

INFORMATION REPORTING AND BACKUP WITHHOLDING TAX

    Under U.S. Treasury regulations, we must report annually to the Internal
Revenue Service and to each non-U.S. holder the amount of dividends paid to such
holder and the tax withheld with respect to such dividends. Copies of the
information returns reporting such dividends and withholding may also be made
available to the tax authorities in the country in which the non-U.S. holder is
a resident under the provisions of an applicable income tax treaty or agreement.

    Currently, United States backup withholding, which generally is a
withholding tax imposed at the rate of 31% on payments to persons that fail to
furnish specified information under the United States information reporting
requirements, generally will not apply:

    - to dividends paid to non-U.S. holders that are subject to the 30%
      withholding discussed above, or that are not so subject because a tax
      treaty applies that reduces or eliminates such 30% withholding; or

                                       79
<PAGE>
    - before January 1, 2001, to dividends paid to a non-U.S. holder at an
      address outside of the United States unless the payor has actual knowledge
      that the payee is a U.S. holder.

Backup withholding and information reporting generally will apply to dividends
paid to addresses inside the United States on shares of our common stock to
beneficial owners that are not "exempt recipients" and that fail to provide
identifying information in the manner required.

    The payment of the proceeds of the disposition of our common stock by a
holder to or through the U.S. office of a broker or through a non-U.S. branch of
a U.S. broker generally will be subject to information reporting and backup
withholding at a rate of 31% unless the holder either certifies its status as a
non-U.S. holder under penalties of perjury or otherwise establishes an
exemption. The payment of the proceeds of the disposition by a non-U.S. holder
of common stock to or through a non-U.S. office of a non-U.S. broker will not be
subject to backup withholding or information reporting unless the non-U.S.
broker has particular types of U.S. relationships. In the case of the payment of
proceeds from the disposition of our common stock effected by a foreign office
of a broker that is a U.S. person or a U.S. related person, existing regulations
require information reporting on the payment unless the broker receives a
statement from the owner, signed under penalty of perjury, certifying its
non-U.S. status or the broker has documentary evidence in its files as to the
non-U.S. holder's foreign status and the broker has no actual knowledge to the
contrary. For this purpose, a U.S. related person is defined as:

    - a "controlled foreign corporation" for U.S. federal income tax purposes;
      or

    - a foreign person 50% or more of whose gross income from all sources for
      the three-year period ending with the close of its taxable year preceding
      the payment, or for such part of the period that the broker has been in
      existence, is derived from activities that are effectively connected with
      the conduct of a U.S. trade or business.

    The U.S. Treasury regulations generally effective for payments made after
December 31, 2000 alter the foregoing rules. Among other things, such
regulations provide presumptions under which a non-U.S. holder is subject to
backup withholding at the rate of 31% and information reporting unless we
receive certification from the holder of non-U.S. status. Depending on the
circumstances, this certification will need to be provided:

    - directly by the non-U.S. holder;

    - in the case of a non-U.S. holder that is treated as a partnership or other
      fiscally transparent entity, by the partners, stockholders or other
      beneficiaries of such entity; or

    - by qualified financial institutions or other qualified entities on behalf
      of the non-U.S. holder.

    Any amounts withheld under the backup withholding rules from a payment to a
non-U.S. holder will be refunded, or credited against the holder's U.S. federal
income tax liability, if any, provided that the required information is
furnished to the Internal Revenue Service.

</TABLE>

    The underwriting agreement provides that the underwriters are obligated to
purchase all of the shares of our common stock offered in this offering if any
are purchased, other than those shares covered by the over-allotment option
described below. The underwriting agreement also provides that if an underwriter
defaults, the purchase commitments of non-defaulting underwriters may be
increased or this offering of our common stock may be terminated.


    We have granted to the underwriters a 30-day option to purchase on a pro
rata basis up to 900,000 additional shares of our common stock at the initial
public offering price less the underwriting discounts and commissions. This
option may be exercised only to cover over-allotments of our common stock.


    The underwriters propose to offer our common stock initially at the public
offering price on the cover page of this prospectus and to the selling group
members at that price less a concession of $  per share. The underwriters and
the selling group members may allow a discount of $  per share on sales to other
broker/dealers. After the initial public offering, the public offering price and
concession and discount to dealers may be changed by the representatives.

    The following table summarizes the compensation and estimated expenses that
we will pay.

    The underwriters have informed us that they do not expect sales to accounts
over which the underwriters exercise discretionary authority to exceed 5% of the
shares of our common stock being offered.

    We, our officers, our directors, most of the former owners of all of the
businesses we acquired, GTCR and Smart Technology have agreed not to offer or
transfer, or file with the Securities and Exchange Commission a registration
statement under the Securities Act relating to, any additional shares of our
common stock or securities convertible into or exchangeable or exercisable for
any shares of our common stock without the prior written consent of Credit
Suisse First Boston Corporation for a period of 180 days after the date of this
prospectus, except in our case for grants of employee stock options under our
stock incentive plans in effect on the date hereof and issuances of securities
as a result of the exercise of any options outstanding on the date hereof and
issuances of securities as a result of the conversion of any convertible
instruments outstanding on the date hereof.

<PAGE>
    The underwriters have reserved for sale, at the initial public offering
price, up to       shares of our common stock for employees and other persons
associated with AppNet who have expressed an interest in purchasing our common
stock in this offering. The number of shares of common stock available for sale
to the general public in this offering will be reduced to the extent these
persons purchase the reserved shares. Any reserved shares not so purchased will
be offered by the underwriters to the general public on the same terms as the
other shares.

    We have agreed to indemnify the underwriters against liabilities under the
Securities Act, or to contribute to payments which the underwriters may be
required to make in that respect.

    We have applied to list the shares of our common stock on The Nasdaq Stock
Market's National Market under the symbol "APNT".

    Prior to this offering, there has been no public market for our common
stock. The initial public offering price for our common stock will be determined
by negotiation between us and the representatives and does not reflect the
market price for our common stock following this offering. Among the principal
factors considered in determining the initial public offering price will be:

    - the information in this prospectus and otherwise available to the
      representatives;

    - market conditions for initial public offerings;

    - the history of and prospects for the industry in which we compete;

    - our past and present operations;

    - our past and present earnings and current financial position;

    - the capability of our management;

    - our prospects for future earnings;

    - the present state of our development and our current financial condition;

    - the recent market prices of, and the demand for, publicly traded common
      stock of generally comparable companies;

    - the general condition of the securities markets at the time of this
      offering; and

    - other relevant factors.

    We can offer no assurances that the initial public offering price will
correspond to the price at which our common stock will trade in the public
market subsequent to this offering or that an active trading market for our
common stock will develop and continue after this offering.

    The representatives may engage in over-allotment, stabilizing transactions,
syndicate covering transactions and penalty bids in accordance with Regulation M
under the Securities Exchange Act of 1934. Over-allotment involves syndicate
sales in excess of the size of this offering, which creates a syndicate short
position. Stabilizing transactions permit bids to purchase the shares of our
common stock so long as the stabilizing bids do not exceed a specified maximum.
Syndicate covering transactions involve purchases of our common stock in the
open market after the distribution has been completed in order to cover
syndicate short positions. Penalty bids permit the representatives to reclaim a
selling concession from a syndicate member when our common stock originally sold
by the syndicate member is purchased in a syndicate covering transaction to
cover syndicate short positions.

    Such stabilizing transactions, syndicate covering transactions and penalty
bids may cause the price of our common stock to be higher than it would
otherwise be in the absence of such transactions. These transactions may be
effected on The Nasdaq Stock Market's National Market or otherwise and, if
commenced, may be discontinued at any time.

                          NOTICE TO CANADIAN RESIDENTS

RESALE RESTRICTIONS

    The distribution of our common stock in Canada is being made only on a
private placement basis exempt from the requirement that we prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of our common stock are effected. Accordingly, any resale of our common
stock in Canada must be made in accordance with applicable securities laws which
will vary depending on the relevant jurisdiction and which may require resales
to be made in accordance with available statutory exemptions or under a
discretionary exemption granted by the applicable Canadian securities regulatory
authority. Purchasers are advised to seek legal advice prior to any resale of
our common stock.

REPRESENTATIONS OF PURCHASERS

    Each purchaser of our common stock in Canada who receives a purchase
confirmation will be deemed to represent to us and the dealer from whom such
purchase confirmation is received that:

    - such purchaser is entitled under applicable provincial securities laws to
      purchase our common stock without the benefit of a prospectus qualified
      under such securities laws;

    - where required by law, that such purchaser is purchasing as principal and
      not as agent; and

    - such purchaser has reviewed the text above under "Resale restrictions."

RIGHTS OF ACTION (ONTARIO PURCHASERS)

    The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
Ontario securities law. As a result, Ontario purchasers must rely on other
remedies that may be available, including common law rights of action for
damages or rescission or rights of action under the civil liability provisions
of the U.S. federal securities law.

ENFORCEMENT OF LEGAL RIGHTS

    All of the issuer's directors and officers as well as the experts named
herein may be located outside of Canada and, as a result, it may not be possible
for Canadian purchasers to effect service of process within Canada upon the
issuer or such persons. All or a substantial portion of the assets of the issuer
and such persons may be located outside of Canada and, as a result, it may not
be possible to satisfy a judgment against the issuer or such persons in Canada
or to enforce a judgment obtained in Canadian courts against such issuer or
persons outside of Canada.

NOTICE TO BRITISH COLUMBIA RESIDENTS

    A purchaser of our common stock to whom the SECURITIES ACT (British
Columbia) applies is advised that such purchaser is required to file with the
British Columbia Securities Commission a report within ten days of the sale of
common stock acquired by such purchaser through this offering. Such report must
be in the form attached to British Columbia Securities Commission Blanket Order
BOR #95/17, a copy of which may be obtained from us. Only one such report must
be filed in respect of shares of our common stock acquired on the same date and
under the same prospectus exemption.

TAXATION AND ELIGIBILITY FOR INVESTMENT

    Canadian purchasers of our common stock should consult their own legal and
tax advisors with respect to the tax consequences of an investment in our common
stock in their circumstances and with respect to the eligibility of our common
stock for investment by the purchaser under relevant Canadian legislation.

    After the 1999 reverse common stock split discussed in Note 18 to AppNet
Systems, Inc.'s consolidated financial statements is effected, we expect to be
in a position to render the following audit report.

                                          ARTHUR ANDERSEN LLP

Washington, D.C.
March 29, 1999

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To AppNet Systems, Inc.:

    We have audited the accompanying consolidated balance sheet of AppNet
Systems, Inc. (a Delaware corporation) and subsidiaries as of December 31, 1998
and the related consolidated statements of operations, stockholders' equity, and
cash flows for the year then ended. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audit.

    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of AppNet
Systems, Inc. and subsidiaries as of December 31, 1998, and the results of their
operations and their cash flows for the year then ended, in conformity with
generally accepted accounting principles.

Washington, D.C.

in Note 18, as to which the date is

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                      DECEMBER 31, 1998 AND MARCH 31, 1999

1.  BUSINESS DESCRIPTION:

    AppNet Systems, Inc. ("AppNet" or the "Company") was incorporated under the
name Internet Applications, Inc. in November 1997 ("Inception"), under the laws
of the state of Delaware. The Company changed its name to AppNet Systems, Inc.,
in March 1998. AppNet is based in Bethesda, Maryland and is a provider of
Internet and electronic commerce professional services and solutions, including
strategic consulting, interactive media services, Internet-based application
development, electronic commerce systems integration and electronic commerce
outsourcing.

    The Company's financial statements for the period from Inception through
December 31, 1997 reflect immaterial transactions and, therefore, have been
included in the 1998 financial statements to facilitate presentation. From
Inception through March 11, 1998, the Company's operating activities related
primarily to recruiting personnel, raising capital, identifying operating assets
for acquisitions and developing technical and marketing materials. In March
1998, the Company completed its first acquisition and recognized its first
revenues.

    There are significant risks associated with the Company, including the
susceptibility of the Company's services to rapid technological change,
increased competition from existing service providers and new entrants, lack of
an operating history, existence of fixed price contracts, realizability of
intangible assets, government regulations, the year 2000 issue and dependence
upon key members of the management team.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES:

PRINCIPLES OF CONSOLIDATION

    The accompanying consolidated financial statements include the accounts of
AppNet and its wholly owned subsidiaries. All significant intercompany
transactions and accounts have been eliminated in consolidation.

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make assumptions that
affect the reported amounts of assets and liabilities and the disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amount of revenues and expenses during the reporting period. Actual
results could differ from those estimates.

CASH AND CASH EQUIVALENTS

    The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                      DECEMBER 31, 1998 AND MARCH 31, 1999

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost, net of accumulated depreciation
and amortization. Depreciation and amortization are computed using the
straight-line method over the estimated useful lives of the related assets, as
follows:

<TABLE>
<S>                                                       <C>
                                                          three to five
Computers and equipment.................................  years
                                                          five to seven
Furniture and fixtures..................................  years
</TABLE>

    Leasehold improvements are amortized over the lesser of the estimated useful
life of the asset or the remaining lease term.

IMPAIRMENT OF LONG-LIVED ASSETS

    In accordance with Statement of Financial Accounting Standards ("SFAS") No.
121, "Accounting for Impairment of Long-Lived Assets and for Long-Lived Assets
to Be Disposed Of," the Company reviews its recorded goodwill, other intangibles
and long-lived assets for impairment whenever events or changes in circumstances
indicate that the carrying amount of an asset may not be recoverable. When
deemed necessary, goodwill and other intangibles are assessed for possible
impairment based upon a number of factors, including turnover of the acquired
workforce and the undiscounted value of expected future operating cash flows in
relation to the Company's net investment in each subsidiary. Since Inception,
the Company has not recorded a provision for possible impairment of long-lived
assets or intangible assets associated with its acquired businesses.

INTERNAL USE COMPUTER SOFTWARE

    In accordance with the American Institute of Certified Public Accountants
(the "AICPA") Statement of Position 98-1 "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use," the Company capitalizes costs
related to software and implementation in connection with its internal use
software systems. Such costs are amortized principally over three years.

FAIR VALUE OF FINANCIAL INSTRUMENTS

    The Company's financial instruments consist primarily of cash and cash
equivalents, accounts receivable, accounts payable, credit facilities, long-term
debt, convertible notes and capital lease obligations. In management's opinion,
the carrying amounts of these financial instruments approximate their fair
values at December 31, 1998. Due to the related party nature of the Company's
Class A Preferred Stock, it is impracticable to estimate its fair value at
December 31, 1998.

STOCK-BASED COMPENSATION

    The Company accounts for stock-based employee compensation arrangements
using the intrinsic value method in accordance with provisions of Accounting
Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to
Employees," and complies with the disclosure provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation." Under APB Opinion No. 25,
compensation cost is generally recognized based on the difference, if any, on
the date of grant between the fair value of the Company's stock and the amount
an employee must pay to acquire the stock.

                      DECEMBER 31, 1998 AND MARCH 31, 1999

REVENUE RECOGNITION

    Revenues from time and materials contracts are recognized based on fixed
hourly rates for direct labor hours expended. Revenues from fixed-price
contracts are recognized on the percentage-of-completion method, with costs and
estimated profits recorded as work is performed. Revenues from
cost-plus-fixed-fee contracts are recognized on the basis of direct costs plus
indirect costs incurred plus a fixed profit percentage. Revenues exclude the
cost of media and advertising purchases reimbursed by clients.

    Cost of revenues includes all direct material and labor costs related to
contract performance and does not include any related depreciation expense.
Provisions for estimated losses on uncompleted contracts are made in the period
in which such losses are determined. Changes in contract performance and
estimated profitability, including final contract settlements, may result in
revisions to costs and revenues and are recognized in the period in which the
revisions are determined. Unbilled receivables on contracts are comprised of
costs, plus earnings on certain contracts in excess of contractual billings on
such contracts. Cash received in excess of costs incurred is classified as
deferred revenue.

BUSINESS CONCENTRATION AND CREDIT RISK

    The following table summarizes the revenues and accounts receivable from
clients in excess of 10% of total revenues and accounts receivable:

</TABLE>

INCOME TAXES

    Income taxes are accounted for using an asset and liability approach that
requires the recognition of taxes payable or refundable for the current year and
deferred tax liabilities and assets for the future tax consequences of events
that have been recognized in the Company's financial statements or tax returns.
The measurement of current and deferred tax liabilities and assets are based on
provisions of the enacted tax law; the effects of future changes in tax laws or
rates are not anticipated. The measurement of deferred tax assets is reduced, if
necessary, by the amount of any tax benefits that, based on available evidence,
are not expected to be realized.

EARNINGS PER SHARE

    SFAS No. 128 "Earnings Per Share," requires the presentation of basic and
diluted earnings per share. Basic net income (loss) per share is computed by
dividing income (loss) attributable to common stockholders by the weighted
average number of common shares outstanding for the period. The diluted net
income (loss) per share data is computed using the weighted average number of
common shares outstanding plus the dilutive effect of common stock equivalents,
unless the common stock equivalents are antidilutive.

RECENT ACCOUNTING PRONOUNCEMENTS

    In April 1998, the AICPA issued Statement of Position 98-5, "Reporting on
the Costs of Start-Up Activities" ("SOP 98-5"). SOP 98-5, which is effective for
fiscal years beginning after December 15, 1998, provides guidance on the
financial reporting of start-up costs and organization costs. It requires costs
for start-up activities and organization costs to be expensed as incurred. As
the Company has expensed these costs historically, the adoption of this standard
is not expected to have a significant impact on its results of operations,
financial position or cash flows.

    In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivatives and Hedging Activities" ("SFAS No. 133"), which
establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts
(collectively referred to as derivatives), and for hedging activities. SFAS No.
133 is effective for all fiscal quarters of fiscal years beginning after June
15, 1999 and management has not yet determined its effect on the Company's
financial statements or disclosures.

ALLOCATION OF PURCHASE CONSIDERATION

    The acquisitions have been accounted for using the purchase method of
accounting and, accordingly, the recognized purchase price has been allocated,
based on preliminary estimates of fair value, to the tangible assets acquired
and liabilities assumed and, with the advice of independent valuation experts,
to the identifiable intangible assets, on the acquisition dates. The Company has
recorded identifiable intangibles on the 1998 Acquired Businesses, as follows:

<TABLE>
<CAPTION>
                                                                  APPRAISED

Proprietary technology.........................................     4,325,000     12-24 months
</TABLE>

    As of December 31, 1998, the purchase price in excess of identified tangible
and intangible assets and liabilities assumed in the amount of $93,159,000 was
allocated to goodwill.

    In the three month period ended March 31, 1999, the Company recorded
identifiable intangibles related to the 1999 Acquisitions of $2,875,000. This
preliminary purchase price allocation also resulted in the allocation of
$43,225,000 to goodwill. Final estimates of fair value will be made upon the
completion of independent valuations for certain 1999 acquisitions and the final
determination of certain preexisting contingencies. As a result of the early
stage of development of the Internet and electronic commerce, the dynamics of
this rapidly evolving industry and the expectation of increasing competition,
the recorded goodwill is being amortized on a straight-line basis over three
years, the estimated period of its benefit.

    The following unaudited pro forma consolidated amounts give effect to the
1998 acquisitions as if they had occurred on January 1, 1998, by consolidating
the results of operations of the 1998 Acquired Businesses with the results of
AppNet for the year ended December 31, 1998. The pro forma amounts do not
purport to be indicative of the results of operations that would have been
achieved had the transactions been in effect as of the beginning of 1998 and
should not be construed as being representative of future results of operations.

</TABLE>

1999 CREDIT FACILITIES

    On January 8, 1999, the Company replaced its two existing credit agreements
("the 1998 Credit Facilities") with two credit agreements (together the "1999
Credit Facilities") entered into with a syndicate of lenders providing for
$55,000,000 in borrowings. The 1999 Credit Facilities consist of $40,000,000 in
credit loans (the "Guaranteed Loans") which have been guaranteed by a
significant stockholder and $15,000,000 of additional credit loans (the
"Unguaranteed Loans"). The 1999 Credit Facilities mature on August 24, 2001. On
March 10, 1999, the Company amended the Unguaranteed Loans increasing available
borrowings from $15,000,000 to $26,000,000. Under the terms of the Unguaranteed
Loans, the amount borrowed cannot, at any time, exceed the amount borrowed under
the Guaranteed Loans.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                      DECEMBER 31, 1998 AND MARCH 31, 1999

    The Guaranteed Loans bear interest, at the Company's option, at various
LIBOR rates plus 2.5 percent or the lenders' base rate plus .5 percent. The
Guaranteed Loans require the Company to pay a quarterly commitment fee of .5
percent on the unused amounts.

    The Unguaranteed Loans bear interest, at the Company's option, at various
LIBOR rates or the lenders' base rate plus an applicable margin, as determined
by the Company's operating performance.

    The 1999 Credit Facilities include certain restrictive covenants which
require the Company, among other things, to maintain minimum levels of earnings
before interest, taxes, depreciation, and amortization, ratios of cash flow to
debt service and place limits on capital expenditures.

1998 CREDIT FACILITIES

    On August 25, 1998, the Company entered into a credit facility with a
commercial lender. The facility provided for borrowings of up to $15,000,000,
bore interest at the lender's base rate plus a defined percentage or at various
LIBOR rates, and was due on demand. For the period from August 25, 1998 to
October 13, 1998, the highest and weighted average balances outstanding under
the facility were $9,800,000 and $8,478,000, respectively.

    On October 13, 1998, the Company modified its facility and entered into two
credit agreements (the "1998 Credit Facilities") with two commercial lenders.
Under the 1998 Credit Facilities, each lender provided a $20 million line of
credit which was payable upon demand, guaranteed by a significant stockholder
and bore interest at the option of the Company at the lenders' base rate plus a
defined percentage or at various LIBOR options plus 2.5 percent. For the period
from October 13, 1998, to December 31, 1998, the highest and weighted average
balances under the 1998 Credit Facilities were $37,461,000 and $36,040,000,
respectively. During this period, the average interest rate was 8.13 percent.
One of the facilities provided for a quarterly commitment fee equal to .05
percent. As a result of the 1999 Credit Facilities, which replaced the 1998
Credit Facilities and qualify for non-current classification, the amounts
outstanding under the 1998 Credit Facilities as of December 31, 1998 have been
classified as long-term in the accompanying balance sheet. In connection with
debt refinancings during 1998, the Company charged to other expense
approximately $291,000 of previously deferred financing fees.

CONVERTIBLE NOTES

    In conjunction with certain of the Acquired Businesses, the Company issued
convertible notes, certain of which, at the option of the holders, allow the
holders to convert the notes to the Company Common Stock upon certain defined
events at either a stated price or a discount to the then current market price
for the Company Common Stock. Upon an initial public offering of the Company's
Common Stock, the Company may be required to record an interest charge of
approximately $875,000 related to certain beneficial conversion rights.

10. CAPITAL STOCK:

1998 COMMON STOCK SPLIT

    In June 1998, upon adoption of the Company's Second Restated Certificate of
Incorporation, a two-for-one stock split of the Company Common Stock was
effected. All share and per-share amounts, including stock option information,
have been restated in these notes and the accompanying financial statements to
reflect this stock split and the 1999 Reverse Common Stock Split (see Note 18).

GTCR INVESTMENT

    In June 1998, the Company completed an investment transaction with GTCR
Golder Rauner, L.L.C. and certain related investment funds ("GTCR") and Smart
Technology, L.L.C. ("Smart Technology"), a party related to the Company's
President and Chief Executive Officer (the "GTCR Investment"). Prior to the GTCR
Investment, the Company had 5,343,860 shares of issued and outstanding common
stock all of which were owned by Company's initial investors (the "Initial
Investors"). Pursuant to the GTCR Investment, the Company made a net redemption
of 1,350,887 shares of Company Common Stock from certain of the Initial
Investors for $.3007 per share or $406,000 and sold an aggregate 11,559,144
shares to GTCR and Smart Technology for $.3007 per share or $3,476,000 before
deduction for expenses and fees. The Company also sold 1,251,228 shares of
Company Common Stock to the Company's President and Chief Executive Officer (the
"Reserved Stock") and 531,773 shares to other certain parties affiliated with
the GTCR Investment. These shares were sold for $.3007 per share.

    GTCR and Smart Technology committed to provide up to an additional
$96,500,000 in capital to the Company to fund acquisitions as well as other
general corporate purposes. Upon the request of the Board and the approval of
GTCR and Smart Technology, shares of Class A Preferred Stock will be issued to
GTCR and Smart Technology in the ratio of 98 percent to 2 percent, respectively,
in exchange for $1,000 per share. No shares of Class A Preferred Stock were
issued at the time of the GTCR Investment. In connection with the issuance of
Class B Preferred Stock as part of the SSC transaction, the capital commitment
from GTCR and Smart Technology was decreased to $84,900,000.

    In connection with the GTCR Investment, the Company entered into a
management services agreement with GTCR for $200,000 per year.

COMMON STOCK SUBJECT TO PUT RIGHTS

    In conjunction with its acquisition of Arbor, the Company issued 266,796
shares of Series A-1 Convertible Preferred Stock with a liquidation value of
$1,100,000. Pursuant to their terms, these shares were converted into 187,225
shares of Company Common Stock at the time of the GTCR Investment. As part of
the GTCR Investment, the Board of Directors authorized the repurchase of 138,455
shares of the common stock issued upon the conversion for $5.70 per share which
provided the holders a return equivalent to the liquidation value of the Series
A-1 Convertible Preferred Stock. In addition, the Board of Directors agreed to
grant the holders of the remaining 48,771 shares of Company Common Stock the
right to require the Company to repurchase their shares for cash at $5.70 per
share beginning on March 11, 1999, and extending for thirty days.

CLASS A PREFERRED STOCK

    The holders of the Class A Preferred Stock ("Class A Preferred Stock") are
entitled to a 6 percent cumulative dividend which is paid when declared by the
Company's Board of Directors. The Company can redeem the shares at any time for
their liquidation value of $1,000 per share plus accrued but unpaid dividends.
The shares have no voting or conversion rights. Upon the earliest of the
liquidation of the Company, a change in the control of the Company, an initial
public offering ("IPO") or other fundamental change in the Company, as defined,
a majority of the holders of the Class A Preferred stock can require the Company
to redeem their shares for their liquidation value, plus accrued but unpaid
dividends. In the case of an IPO, the redemption is limited to the net funds
available from the IPO. GTCR holds approximately 97 percent of the outstanding
Class A Preferred Stock.

    The Company incurred certain fees associated with the issuance of the Class
A Preferred Stock. Through December 31, 1998, the Company paid a one percent fee
of $369,000 to GTCR based on the issuance of the Company's Class A Preferred
Stock to GTCR. The Company also incurred a commission of $262,000 to one of the
Company's directors in connection with purchases of Class A Preferred Stock.
These costs were deducted from the proceeds of the Class A Preferred Stock shown
in the accompanying balance sheet. The Class A Preferred Stock is being accreted
to its liquidation value over the period to its estimated redemption date, which
is expected to occur in 1999. The accretion of the costs associated with the
Class A Preferred Stock was $184,000 for the year ended December 31, 1998 and is
classified as dividends on and accretion of preferred stock in the accompanying
statements of operations and stockholders' equity.

CLASS B PREFERRED STOCK

    The holders of Class B Preferred Stock are entitled to a 6 percent
cumulative dividend which is paid when declared by the Company's Board of
Directors. The shares have no voting rights. The Company has the contractual
ability to redeem or convert all outstanding shares of Class B Preferred Stock
upon an initial public offering.

STOCK WARRANTS

    The Company has issued warrants to purchase 84,795 shares of Company Common
Stock at $.3007 per share, of which 70,175 are held by Smart Technology. The
values attributable to these warrants at the time of issuance are not
significant and, therefore, have not been separately presented in the

purchase 121 shares of Class A Preferred Stock at $1,000 per share.

RESERVED STOCK

    The Reserved Stock is subject to a Senior Management Agreement dated June
29, 1998 (the "Agreement") with the Company's President and Chief Executive
Officer. At the time of the GTCR Investment, 1,251,228 shares of Reserved Stock
were purchased at a price of $.3007 per share in exchange for cash equal to the
par value of the stock and a promissory note equal to the remaining balance.
Pursuant to the Agreement, the Company may, at its discretion, repurchase any or
all of the Reserved Stock for the $.3007 per share paid by the executive in
order to issue a corresponding number of shares and options to purchase shares
to certain employees. The Company's right to repurchase the Reserved Stock
expires on the first to occur of (a) a sale of the Company, (b) the failure by
GTCR to own 50 percent of the original number of Company Common Shares it
purchased in conjunction with the GTCR Investment and (c) an IPO ("Qualifying
Events"). As of December 31, 1998, the Company's President and Chief Executive
Officer had 659,649 shares of Reserved Stock remaining. Additional shares were
repurchased subsequent to year end reducing the total shares outstanding to
210,119 as of March 29, 1999.

    Because the number of recorded shares to be held by the executive is not
fixed, the Company will record a charge to income equal to the difference
between the fair value of the Company's stock on the date of the Qualifying
Event and $.3007, multiplied by the number of remaining Reserved Shares retained
by the executive following the occurrence of the Qualifying Event.

SALES TO MANAGEMENT

    Shortly after the GTCR Investment, the Company sold 503,860 shares of
Company Common Stock to management for $.3007 per share, the fair value at that
time. In November 1998, the Company sold 49,123 shares of Common Stock to a
member of management for $8.55 per share, the fair value at that time.

11. RETIREMENT PLAN:

    During 1998, the Company maintained various 401(k) plans for its employees.
These plans had been established by the 1998 Acquired Businesses prior to
acquisition. Effective February 1, 1999, the employees of the 1998 Acquired
Businesses began making contributions to the AppNet plan. During 1998, the
Company's expense under these plans totaled $281,000.

    Effective February 1, 1999, the Company established a 401(k) retirement plan
for the benefit of all eligible employees. Participants may contribute up to 15
percent of their annual compensation to the plan. Employee contributions are
fully vested. The Company will match 50 percent of each employees' contributions
up to six percent of each employees' salary. The Company may also elect to make
a discretionary contribution as determined by its Board of Directors on an
annual basis. Employees will fully vest in the Company's matching and any
discretionary contributions ratably over three years.

12. EMPLOYEE STOCK OPTION PLANS:

    The Company had two stock option plans as of December 31, 1998, which were
the 1998 Stock Option and Incentive Plan and an incentive stock option plan
assumed in connection with the

acquisition of Century (the "Century Plan"). Options under these plans expire no
later than ten years from the date of the grant or when employment ceases,
whichever comes first. The maximum number of shares of common stock which may be
issued pursuant to the stock option plans is 913,042 at December 31, 1998.

    Options granted under the stock option plan are accounted for under APB
Opinion No. 25, and since options have been granted at prices equal to the fair
value of the Company's Common Stock on the date of grant, no compensation
expense has been recognized for the option grants. Certain options converted
from the 1998 Acquired Businesses have exercise prices ranging from $.06 to
$8.69. The value of these options was included in the purchase price of the 1998
Acquired Businesses. Had compensation cost for the plan been determined based on
the estimated fair value of the options at the grant dates consistent with the
method of SFAS No. 123, pro forma net loss attributable to common stockholders
would have been approximately $15,408,000 or a net loss of $1.43 per share for
1998. The weighted average fair value of the options granted by the Company
during 1998 is estimated to be $3.85 per option assuming the following: no
dividend yield, risk-free interest rate of 5 percent, an expected term of the
options of four years and an expected volatility of 45 percent.

    The following summarizes option activity during 1998:

    Subsequent to December 31, 1998, the Company issued options to purchase
882,883 shares of Company Common Stock.

    In March 1999, the Company issued 337,776 stock options to a member of
management. These options have an exercise price of $12.83 and vest ratably over
4 years. As a result of this grant, the Company recorded deferred compensation
of $481,000. The amount of deferred compensation was based on the difference
between the estimated fair market value of the Company Common Stock at the date
of grant, as determined by the most recent third party stock transaction, and
the stated exercise price. The Company amortized $4,000 of the deferred
compensation for the three months ended March 31, 1999 in the unaudited
consolidated statement of operations.

    Shares of common stock which are contingently payable pursuant to the
acquisition agreements (Note 16) are not included in the calculation of weighted

14. INCOME TAXES:

    The Company follows the provisions of SFAS No. 109, "Accounting for Income
Taxes," for financial reporting purposes. Deferred tax assets or liabilities at
the end of each period are determined using the currently enacted tax rates to
apply to taxable income in the period in which the deferred tax asset or
liability is expected to be settled or realized.

    As of December 31, 1998 and March 31, 1999, the Company had approximately
$4.2 million and $7.9 million (unaudited), respectively, of net operating loss
carryforwards which begin to expire in 2018. The Company has recorded a
valuation allowance for deferred tax assets as of December 31, 1998, of
$1,317,000. In assessing the realizability of deferred tax assets, management
considers whether it is more likely than not that some portion or all of the
deferred tax assets will not be realized. The ultimate realization of deferred
tax assets is dependent upon the generation of future taxable income during the
periods in which those temporary differences become deductible. Management
considers the scheduled reversal of deferred tax liabilities, projected future
taxable income, and tax planning strategies in making this assessment.

15. RELATED PARTIES:

    At December 31, 1998, the Company was owed $821,000 from members of
management. These borrowings are due at varying dates through November, 2008.

    At December 31, 1998, the Company had outstanding borrowings of $150,000
from Smart Technology, $50,000 from a member of management, and $406,000 from
one of the Company's Initial Investors. Also, the convertible notes of
$4,306,000 as of December 31, 1998 and the notes payable for $1,000,000 are due
to former shareholders of the Acquired Businesses, the majority of whom are
current AppNet employees. Subsequent to December 31, 1998, the Company issued
convertible notes of $10,300,000 due to former shareholders of one of the 1999
Acquired Businesses, both of whom are current AppNet employees. The Company also
issued, subsequent to December 31, 1998, a convertible note of $1,000,000 to a
trust established for employees of one of the 1999 Acquired Businesses. Since
the trust is available to the Company's creditors, the trust's assets are
included in these financial statements. As such, the trust's note receivable and
the Company's convertible note payable held by the trust have been eliminated in
consolidation.

    In December 1997, the Company entered into an agreement which was
consummated in 1998 to purchase a 50 percent ownership interest in AppNet
Commerce Services, Inc. ("ACS"). ACS was established to conduct electronic
commerce transaction processing. The remaining 50 percent interest in ACS is
owned by another company. In 1998, due to the failure of the venture to maintain
its customer base and to generate sufficient revenues to cover operating
expenses, the Company determined that its investment was impaired and recorded a
charge of approximately $300,000 which is included in the accompanying statement
of operations as a component of other expense. As of December 31, 1998, the
investment in ACS has a value of zero.

    During 1998, the Company was party to a professional services agreement with
one of its directors. The agreement provided for the payment of $17,000 per
month. The Company incurred approximately $200,000 related to this agreement in
1998. In addition, the Director received a fee of $350,000 in association with
the GTCR Investment. The professional services agreement also provides for a one
percent commission on certain issuances Class A Preferred Stock (Note 10). The
Company also paid approximately $336,000 related to certain fees and a
professional services agreement with one of its initial investors.

LITIGATION AND CLAIMS

    In connection with the acquisition of Internet Outfitters, approximately
$1,450,000 of the purchase price in the form of shares of Company Common Stock,
based upon the fair value of $17.10 per share at the date of acquisition, was
pledged to the Company and escrowed to be available to satisfy any potential
liability in connection with a license dispute. The Company also held back
$750,000 of the cash purchase price to be used to satisfy this and any other
indemnification claims.

    The Company is subject to lawsuits, investigations and claims arising out of
the ordinary course of business, including those related to commercial
transactions, contracts, government regulation and employment matters. Certain
claims, suits and complaints have been filed or are pending against the Company.
In the opinion of management, based on all known facts, all matters are without
merit, and except as related to the aforementioned Internet Outfitters claim,
are of such kind, or involve such amounts, as would not have a material effect
on the financial position or results of operations of the Company if disposed of
unfavorably.

CONTINGENT PAYMENTS

    The Company's acquisition of NMP provided for additional contingent payments
of up to $14,000,000 as of December 31, 1998 in the form of cash and Company
Common Stock to be made to the former owners of NMP if NMP reaches certain
revenue and earnings before interest, taxes, depreciation, and amortization
targets for the period from October 1, 1998 to September 30, 1999. The amount of
this contingent payment varies based on a sliding scale of revenues and earnings
before interest, taxes, depreciation, and amortization. If these goals are
reached, approximately 42 percent of

                      DECEMBER 31, 1998 AND MARCH 31, 1999

the contingent consideration will be reflected as additional purchase
consideration if and when paid. The remaining 58 percent of the contingent
consideration will be paid only if the targets are reached and certain NMP
employees remain employed by the Company. Accordingly, pursuant to the consensus
reached in Emerging Issues Task Force Issue 95-08, "Accounting for Contingent
Consideration Paid to the Shareholders of an Acquired Company in a Purchase
Business Combination," ("EITF 95-08") an estimate of the amount expected to be
paid to these employees will be reflected as stock-based and other
acquisition-related compensation expense ratably over the period which these
employees must remain employed to receive the contingent consideration.
Revisions to this estimate will be reflected on a prospective basis each
reporting period until paid. The accompanying statement of operations reflects a
charge of $1,157,000 of stock-based and other acquisition related compensation
for this contingent payment.

    The Company's acquisitions of Sigma6, Salzinger, Internet Outfitters and
Transform IT provided for contingent payments of up to $14,800,000 (unaudited)
in the form of cash and Company Common Stock to be made to the former owners of
these companies if these entities reach certain revenue and earnings targets for
periods ranging from 9 - 18 months from the date of their acquisition. The
amount of these contingent payments varies based on a sliding scale of revenues
and earnings, as defined in the acquisition agreements.

    If these goals are reached for Salzinger and Sigma6, the amount will be paid
only if the targets are reached and certain Sigma6 and Salzinger employees
remain employed by the Company. Accordingly, pursuant to EITF 95-08, an estimate
of the amount to be paid to these employees will be reflected as stock-based and
other acquisition-related compensation expense ratably over the period which the
employees must remain employed to receive the contingent consideration.
Revisions to this estimate will be reflected on a prospective basis each
reporting period until paid.

    If these goals are reached for Internet Outfitters and Transform IT,
approximately 23 and 33 percent, respectively, of the contingent payment will be
reflected as additional purchase price consideration if and when paid. The
remaining contingent amounts will be paid only if the targets are reached and
certain Internet Outfitters and Transform IT employees remain employed by the
Company. Accordingly, pursuant to EITF 95-08, an estimate of the amount to be
paid to these employees will be reflected as stock-based and other
acquisition-related compensation expense ratably over the period which the
employees must remain employed to receive the contingent consideration.
Revisions to this estimate will be reflected on a prospective basis each
reporting period until paid.

17. SEGMENT INFORMATION:

    The Company currently operates in two operating segments: professional
services and electronic commerce processing. For the year ended December 31,
1998 and the three months ended March 31, 1999, the electronic commerce
processing segment was not significant to the overall financial statements.

18. 1999 COMMON STOCK SPLIT (UNAUDITED)

    The Company is currently contemplating an initial public offering. Prior to
the effectiveness of the initial public offering, the Company intends to enter
into an agreement to exchange the Class A Preferred Stock and the Class B
Preferred Stock, not redeemed with the proceeds of the initial public offering,
into Company Common Stock based on the per share price in the initial public
offering, and declare a one for 2.85 reverse stock split. All share and
per-share amounts, including stock option information, have been restated in
these notes and the accompanying consolidated financial statements to reflect
this reverse stock split.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Software Services Corporation:

    We have audited the accompanying balance sheets of Software Services
Corporation (a Michigan corporation) as of December 31, 1996 and 1997, and
August 24, 1998, and the related statements of operations, stockholders' equity
and cash flows for the years ended December 31, 1996 and 1997, and for the
period from January 1, 1998 to August 24, 1998. These financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Software Services
Corporation as of December 31, 1996 and 1997, and August 24, 1998, and the
results of its operations and its cash flows for the years ended December 31,
1996 and 1997, and for the period from January 1, 1998 to August 24, 1998, in
conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

                DECEMBER 31, 1996 AND 1997, AND AUGUST 24, 1998

1.  BUSINESS DESCRIPTION:

    Software Services Corporation (the Company) engages in application
development, computer software and networking projects, and provides both
full-time and temporary personnel to companies in the computer industry. The
Company is headquartered in Ann Arbor, Michigan.

    On August 25, 1998, all of the outstanding Common Stock of the Company was
acquired by SSC Acquisition Sub. No. 1, Inc. (a Michigan Corporation and a
wholly owned subsidiary of AppNet Systems, Inc.; "AppNet"). In contemplation of
the acquisition, AppNet advanced the Company $3,344,000 to fund the repayment of
certain debt, the repurchase of certain shares, pay the Company's obligation
under a deferred compensation agreement and to fund certain acquisition expenses
paid by the Company. This amount has been included as paid in capital in the
accompanying financial statements.

    There are significant risks associated with the Company, including the
subjectivity of the Company's services to rapid technological change and the
Year 2000 issue.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES:

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

INVESTMENT IN AFFILIATE

    Investment in affiliate represented the Company's 10 percent interest in
Workwell Health & Safety Systems, Inc. ("Workwell"). In addition to the
investment in Workwell, the Company held an option to purchase an additional
2,353 to 2,667 shares of Workwell for $75,000. In January 1997, the Company
exercised this option and signed an agreement to sell its total investment in
Workwell for $490,000. In connection with the sale, certain employment
agreements and options were canceled and the owners of Workwell released the
Company from further payments owed under the non-competition agreements. Except
for the release of payments, all the terms and conditions of the non-competition
agreements remain in full force and effect. During 1997, the Company recognized
a $358,000 gain on this transaction; $93,000 of which represents the release of
payments by the Company under the non-competition agreements.

CASH AND CASH EQUIVALENTS

    The Company considers all investments purchased with a maturity of three
months or less to be cash equivalents.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                DECEMBER 31, 1996 AND 1997, AND AUGUST 24, 1998

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost, net of accumulated depreciation
and amortization. Depreciation and amortization are computed using the
straight-line method over the estimated useful lives of the related assets, as
follows:

<TABLE>
<S>                                                       <C>
                                                          three to five
Computers and equipment.................................  years
Furniture and fixtures..................................  five years
</TABLE>

    Purchased software and third-party costs incurred to develop software for
internal use are capitalized and amortized principally over three years.

    In accordance with SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," the Company
reviews its recorded long-lived assets for impairment whenever events or changes
in circumstances indicate that the carrying amount of an asset may not be
recoverable.

GOODWILL

    Goodwill represents the excess of the purchase price over the fair value of
net assets acquired and is amortized on a straight-line basis over 5 years.

NON-COMPETITION AGREEMENTS

    Non-compete agreements were entered into with former owners of various
acquisitions of the Company and are being amortized on a straight-line basis
over the lives of the related agreements, generally four to five years.

INTELLECTUAL PROPERTY

    Intellectual property represents acquired and internally developed patents.
The Company capitalizes the direct external costs of acquiring the related
patents. Intellectual property is amortized on a straight-line basis over the
lives of the related assets, generally five years.

FAIR VALUE OF FINANCIAL INSTRUMENTS

    The Company's financial instruments consist primarily of cash and cash
equivalents, accounts receivable, accounts payable, short-term borrowings,
long-term debt and capital lease obligations. In management's opinion, the
carrying amounts of these financial instruments approximated their fair values
at December 31, 1996 and 1997, and August 24, 1998.

SELF INSURANCE

    The Company partially self insures its dental, vision and short-term
disability programs. There are stop-loss provisions on each of these programs.
Paid claims were $54,000 and $64,000 in 1996 and 1997, respectively, and $47,000
for the period from January 1, 1998 through August 24, 1998.

STOCK-BASED COMPENSATION

    The Company accounts for stock-based compensation arrangements using the
intrinsic value method in accordance with provisions of Accounting Principles
Board ("APB") Opinion No. 25,

                                      F-34

"Accounting for Stock Issued to Employees," and complies with the disclosure
provisions of SFAS No. 123, "Accounting for Stock-Based Compensation." Under APB
Opinion No. 25, compensation cost is recognized based on the difference, if any,
on the date of grant between the fair value of the Company's stock and the
amount an employee must pay to acquire the stock.

REVENUE RECOGNITION

    Revenues from time and material contracts are recognized based on fixed
hourly rates for direct labor hours expended.

    Costs of revenues include all direct, material and labor costs related to
contract performance and does not include any related depreciation expense.

BUSINESS CONCENTRATION AND CREDIT RISK

    The following table summarizes the revenues and accounts receivable from
clients in excess of 10% of total revenues and accounts receivable:

</TABLE>

- ------------------------

*   Represents less than 10 percent of total.

INCOME TAXES

    The Company accounts for income taxes under Statement of Financial
Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes". Under the
provisions of SFAS No. 109, deferred income taxes reflect the impact of
temporary differences between the amount of assets and liabilities recognized
for financial reporting purposes and such amounts recognized for tax reporting
purposes. Deferred tax assets may also be recognized to reflect the expected
future benefit from the utilization of net operating loss and tax credit
carryforwards. Deferred tax assets and liabilities are measured by applying
current enacted tax laws.

EARNINGS PER SHARE

    SFAS No. 128, "Earnings Per Share," requires the presentation of basic and
diluted earnings per share. Basic net income (loss) per share is computed by
dividing income (loss) available to common stockholders by the weighted average
number of common shares outstanding for the period. The diluted net income
(loss) per share data is computed using the weighted average number of common
shares outstanding plus the dilutive effect of common stock equivalents, unless
the equivalents are antidilutive.

RECENT ACCOUNTING PRONOUNCEMENTS

    In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position ("SOP") 98-1, "Accounting for the Cost of Computer
Software Developed or Obtained for Internal Use." SOP 98-1 is effective for
financial statement years beginning after December 15, 1998. SOP 98-1 provides
guidance on accounting for computer software developed or obtained for internal
use, including the requirements to capitalize specified costs and the
amortization of such costs. The Company does not expect the adoption of this
standard to have a material effect on the Company's capitalization policy.

    Certain amounts from the prior year financial statements have been

                DECEMBER 31, 1996 AND 1997, AND AUGUST 24, 1998

1996 and 1997, and as of August 24, 1998, 180,000, 260,000 and zero options were
outstanding, respectively. In contemplation of the sale of the Company to
AppNet, certain option vesting was accelerated and all then vested options,
totaling 89,500, were redeemed and the remaining options of the Company were
converted to equivalent options of AppNet for $3.43 per share. The amount paid
to the stockholders, net of the option exercise price, has been recognized as
expense and included in stock-based and acquisition-related compensation in the
accompanying statement of operations. In contemplation of the redemption of the
shares, AppNet advanced approximately $217,000 to the Company to fund the
redemption. The funds advanced to the Company have been recorded as additional
paid in capital in the accompanying financial statements.

    Utilizing the intrinsic value method of accounting for the value of stock
options issued during the years ended December 31, 1996 and 1997 and for the
period from January 1, 1998 to August 24, 1998, no compensation cost was
recorded in the accompanying statements of income. Had compensation cost been
determined based on the fair value at the date of grant for awards for the years
ended December 31, 1996 and 1997 and for the period from January 1, 1998 to
August 24, 1998, consistent with the provisions of SFAS No. 123, net income
(loss) would not have significantly differed from the reported amounts.

12. EARNINGS PER SHARE:

    The impact of stock options are excluded from diluted earnings per share due
to their antidilutive effect and are 180,000, 260,000, and zero for the years
ended December 31, 1996 and 1997 and for the period from January 1, 1998 to
August 24, 1998.

13. INCOME TAXES:

    The components of the provision (benefit) for income taxes as recorded under
SFAS No. 109 are as follows:

approximately $90,000 in 1996 and 1997 and $58,000 in the period from January 1,
1998 through August 24, 1998.

15. RETIREMENT PLAN:

    The Company maintains a profit sharing and retirement plan under the
provisions of section 401(k) of the Internal Revenue Code. The Plan provides for
contribution by employees and a discretionary contribution by the Company. The
Plan is for the benefit of all employees. Employees are eligible to participate
if they are at least 18 years of age and have met certain minimum service
requirements. Employee contributions are fully vested and subject to statutory
limits. The Company's contribution is discretionary and is determined by its
Board of Directors. Company contributions vest after three years of service.
There were no company contributions for the year ended December 31, 1996 and
1997, and for the period from January 1, 1998 to August 24, 1998.

16. TERMINATION AGREEMENT:

    During 1997, the Company entered into an agreement to terminate an
employment agreement with a key employee of the Company (the "Termination
Agreement"). Under the terms of the Termination Agreement, the Company was to
pay the former employee a total of $662,000 as satisfaction of any claims the
former employee may have had under the employment agreement. The amount was
payable in the form of 10,000 shares of the Company's common stock valued at
$60,000 and $602,000 in the form of a note. The Note was payable in quarterly
installments of $50,000 through December 1999, with a final payment of $30,000
in March 2000. The Company recorded the net present value of this note,
discounted at 5.5 percent, in the accompanying financial statements as deferred
compensation, which is included in long-term debt. This note was fully repaid
during the period from January 1, 1998 through August 24, 1998.

17. DEFERRED COMPENSATION AGREEMENT:

    The Company has entered into a deferred compensation agreement (the
"Agreement") with the president of the Company. Under the terms of the
Agreement, the president is to receive certain compensation should the Company
be sold or merged, as defined in the Agreement. As a result of the sale of the
Company to AppNet, the Company recognized $2,437,000 in compensation expense
during the period from January 1, 1998 through August 24, 1998, which has been
included in general and administrative expense in the accompanying statement of
operations. In contemplation of this compensation being paid, AppNet advanced
funds to the Company to pay its obligation under the Agreement. The funds
advanced from AppNet have been included as paid in capital in the accompanying
financial statements.

18. SEGMENT DISCLOSURE:

    The Company has adopted SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information." SFAS No. 131 establishes standards for
reporting information about operating segments in annual financial statements
and requires selected information about operating segments in interim financial
reports issued to stockholders. It also establishes standards for related
disclosures about products and services, geographic areas and major customers.

    The Company operated in two operating segments: technical consulting and
managed services. The technical consulting group primarily provides information
technology consulting to companies on a per diem basis. The managed services
group provides information technology solutions to its customers through the
design and implementation of information systems technology on a project or
solutions basis. Substantially all of the Company's revenues are generated and
assets are located in the Midwestern United States.

    The accounting policies of the segments are the same as those described in
the summary of significant accounting policies (Note 2) except that certain
deferred compensation, merger related costs, interest expense and income taxes
have not been allocated to the business segments. The Company evaluates the
performance of its operating segments based primarily upon revenues and
operating income. Assets are not allocated to the operating segments.

    As summary of the Company's operating segments for the years ended December
31, 1996 and 1997 for the period from January 1, 1998 to August 24, 1998, is set
forth below.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Arbor Intelligent Systems, Inc.:

    We have audited the accompanying balance sheets of Arbor Intelligent
Systems, Inc. (a Michigan corporation), as of December 31, 1997, and March 11,
1998, and the related statements of operations, stockholders' deficit, and cash
flows for the year ended December 31, 1997, and for the period from January 1,
1998 to March 11, 1998. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Arbor Intelligent Systems,
Inc. as of December 31, 1997, and March 11, 1998, and the results of its
operations and its cash flows for the year ended December 31, 1997, and for the

                         NOTES TO FINANCIAL STATEMENTS

                      DECEMBER 31, 1997 AND MARCH 11, 1998

1.  BUSINESS DESCRIPTION:

    Arbor Intelligent Systems, Inc. ("Arbor" or the "Company") was incorporated
on August 31, 1988, under the laws of the state of Michigan. The Company is an
Internet-based applications development group providing object-oriented
development services. The Company is headquartered in Ann Arbor, Michigan, and
operates primarily in the surrounding Ann Arbor area.

    On March 12, 1998, certain assets and liabilities of the Company were
acquired by AppNet Systems, Inc. ("AppNet"). The Company incurred $198,000 of
expenses in conjunction with the sale to AppNet primarily for early debt
retirement. This has been classified in other expenses in the accompanying
statements of operations.

    There are significant risks associated with the Company, including the
subjectivity of the Company's services to rapid technological change and the
Year 2000 issue.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES:

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of revenues and expenses during the reporting
period. Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS

    The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost, net of accumulated depreciation
and amortization. Depreciation and amortization are computed using the
straight-line method over the estimated useful lives of the related assets, as
follows:

<TABLE>
<S>                                                        <C>
                                                           three to five
Computers, equipment and software........................  years
Furniture and fixtures...................................  seven years
</TABLE>

    Purchased software and third-party costs incurred to develop software for
internal use are capitalized and amortized principally over three years.

    In accordance with Statement of Financial Accounting Standards ("SFAS") No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of," the Company reviews its recorded long-lived assets
for impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable.

                      DECEMBER 31, 1997 AND MARCH 11, 1998

SOFTWARE DEVELOPMENT COSTS

    The Company has capitalized costs related to the development of certain
software products. In accordance with SFAS No. 86, "Accounting for the Costs of
Computer Software to Be Sold, Leased, or Otherwise Marketed," capitalization of
costs begins when technological feasibility has been established and ends when
the product is available for general release to customers. Amortization has been
computed and recognized based on the products' estimated economic lives of two
years. Capitalized costs and amortization periods are management's estimates and
are subject to change due to rapid technological changes in software
development.

FAIR VALUE OF FINANCIAL INSTRUMENTS

    The Company's financial instruments consist primarily of cash and cash
equivalents, accounts receivable, accounts payable, short-term borrowings,
long-term debt and capital lease obligations. In management's opinion, the
carrying amounts of these financial instruments approximated their fair values
at December 31, 1997, and March 11, 1998.

STOCK-BASED COMPENSATION

    The Company accounts for stock-based employee compensation arrangements
using the intrinsic value method in accordance with provisions of Accounting
Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to
Employees," and complies with the disclosure provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation." Under APB Opinion No. 25,
compensation cost is recognized based on the difference, if any, on the date of
grant between the fair value of the Company's stock and the amount an employee
must pay to acquire the stock.

REVENUE RECOGNITION

    Revenues from time and material contracts are generally recognized based on
fixed hourly rates for direct labor hours expended.

    Costs of revenues include all direct material and labor costs related to
contract performance and does not include any related depreciation expense.

    Revenues from software product sales are recognized when the related product
is delivered, provided no significant vendor obligations remain. Revenues from
all maintenance agreements are recognized ratably over the term of the
agreement, generally one year.

    The following table summarizes the revenues and accounts receivable from
clients in excess of 10% of total revenues and accounts receivable:

INCOME TAXES

    The Company, with the consent of its shareholders, has elected to be taxed
pursuant to Subchapter S of the Internal Revenue Code (an "S corporation"). In
lieu of corporation income taxes, the shareholders of an S corporation are taxed
on their proportionate share of the Company's taxable income. Therefore, no
provision for federal income taxes has been included in the accompanying
financial statements.

RECENT ACCOUNTING PRONOUNCEMENTS

    In March 1998, the AIPCA issued Statement of Position 98-4 ("SOP 98-4"),
"Deferral of the Effective Date of a Provision of SOP 97-2." SOP 98-4 defers for
one year the application of certain provisions of Statement of Position 97-2
("SOP 97-2"), "Software Revenue Recognition." The Company does not expect the
adoption of SOP 97-2 or 98-4 to have a material effect on the Company's results
of operations, financial position or cash flows.

                      DECEMBER 31, 1997 AND MARCH 11, 1998

9.  RETIREMENT PLAN:

    The Company maintains a profit-sharing and retirement plan under the
provisions of section 401(k) of the Internal Revenue Code. The Plan provides for
contributions by employees and a discretionary contribution by the Company. The
Plan is for the benefit of all employees. Participants may contribute up to 18%
of their compensation, subject to statutory limits. Employee contributions are
fully vested. The Company's contribution is discretionary and is determined by
its Board of Directors. Company contributions vest after five years of service.
There were no Company contributions for the year ended December 31, 1997 and for
the period from January 1, 1998 to March 11, 1998.

    Effective February 1, 1999, Arbor employees are covered by the AppNet 401(k)
Plan.

10. EMPLOYEE STOCK RIGHTS:

    The Company maintained a stock rights program for key employees. Pursuant to
the program, granted rights to acquire stock expired at the earlier of ten years
from the grant date or the termination of employment. The grants had value to
the employee only upon an equity transaction such as a public sale of common
stock or acquisition. Prior to the acquisition of the Company by AppNet, no
compensation expense had been recognized for these granted rights as such an
equity event was not deemed probable. Immediately prior to the AppNet
acquisition, rights to acquire 4,640 shares of common stock were exercised. A
charge of $465,000 which reflects the fair value of the Arbor common stock
acquired through exercise of these rights (as determined by the AppNet
acquisition) has been reflected as stock-based compensation in the accompanying
statement of operations in the period from January 1, 1998 to March 11, 1998.

    The following summarizes rights during 1997 and for the period from January
1, 1998 to March 11, 1998:

subjectivity of the Company's services to rapid technological change and the
Year 2000 issue.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES:

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of revenues and expenses during the reporting
period. Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS

    The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost, net of accumulated depreciation
and amortization. Depreciation and amortization are computed using the
straight-line method over the estimated useful lives of the related assets, as
follows:

<TABLE>
<S>                                                              <C>
                                                                 three
Computer equipment.............................................  years
                                                                 seven
Furniture and fixtures.........................................  years
</TABLE>

    Purchased software is capitalized and amortized principally over three
years. Leasehold improvements are amortized over the lesser of the estimated
useful life of the asset or the remaining lease term.

    In accordance with Statement of Financial Accounting Standards ("SFAS") No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of," the Company reviews its recorded long-lived assets
for impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable.

FAIR VALUE OF FINANCIAL INSTRUMENTS

    The Company's financial instruments consist primarily of cash and cash
equivalents, accounts receivable, accounts payable, long-term debt, capital
lease obligations and Mandatorily Redeemable

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

             AS OF DECEMBER 31, 1996 AND 1997, AND OCTOBER 1, 1998

Preferred Stock. In management's opinion, the carrying amounts of these
financial instruments approximated their fair values at December 31, 1996 and
1997, and October 1, 1998.

CAPITAL STOCK

    On December 8, 1997, the Board of Directors approved a common stock split of
625-to-1. In addition, on April 23, 1998, the Board of Directors approved a
common and preferred stock split of ten-to-one. All share amounts in the
accompanying financial statements have been retroactively adjusted to reflect
these splits.

    In March 1998, the Company amended and restated its Articles of
Incorporation. The amended and restated Articles of Incorporation increased the
authorized number of shares of no par common stock to 7,500,000 shares and
authorized 1,428,570 shares of a new class of $0.0875 cumulative annual
dividend, nonparticipating, convertible, redeemable, voting, no par preferred
stock called the Series A Convertible Preferred Stock (the "Mandatorily
Redeemable Preferred Stock"). The Company issued 1,428,570 shares of the
Mandatorily Redeemable Preferred Stock for net proceeds of $1,230,000. Dividends
on the Mandatorily Redeemable Preferred Stock were to cease to accrue on the
sixth anniversary of the issue date. In the event of liquidation, holders of the
Mandatorily Redeemable Preferred Stock would have first received an amount per
share equal to the original issue price of the shares plus accrued but unpaid
dividends thereon and then participate pro rata with the holders of the
Company's common stock in the distribution of any remaining funds in excess of
$5,000,000. Each share of Mandatorily Redeemable Preferred Stock was convertible
at any time at the option of the holder into one share of common stock, subject
to adjustment as a result of the occurrence of certain events. Further,
beginning on March 5, 2004, the Company would have been required, at the request
of the holders, to redeem at the original issue price plus accrued but unpaid
dividends, at least 10 percent of the outstanding Mandatorily Redeemable
Preferred Stock on each successive calendar quarter until all shares had been
redeemed. The dividend on the Mandatorily Redeemable Preferred Stock was
originally due March 1999. The holders of the Mandatorily Redeemable Preferred
Stock forgave payment of this dividend in conjunction with NMP's purchase by
AppNet.

    The Company's common stock, including common stock which may be authorized
and issued in the future, is subject to a Shareholders' Agreement, which
includes certain co-sale rights, transfer restrictions, and buy back rights. On
April 23, 1998, the Board of Directors approved an increase in the authorized
number of shares of common and preferred stock to 8,550,000 and 1,450,000,
respectively.

STOCK-BASED COMPENSATION

    The Company accounts for stock-based employee compensation arrangements
using the intrinsic value method in accordance with provisions of Accounting
Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to
Employees," and complies with the disclosure provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation." Under APB Opinion No. 25,
compensation cost is recognized based on the difference, if any, on the date of
grant between the fair value of the Company's stock and the amount an employee
must pay to acquire the stock.

REVENUE RECOGNITION

    Revenues from time and materials contracts are recognized based on fixed
hourly rates for direct labor hours expended. Revenues from fixed-price
contracts are recognized on the percentage-of-

completion method, with costs and estimated profits recorded as work is
performed. Revenues exclude the costs of media and advertising purchases
reimbursed by clients.

    Cost of revenues include all direct material and labor costs related to
contract performance, and does not include any related depreciation expense.
Provisions for estimated losses on uncompleted contracts are made in the period
in which such losses are determined. Changes in job performance and estimated
profitability, including final contract settlements, may result in revisions to
costs and income and are recognized in the period in which the revisions are
determined. Unbilled receivables on contracts are comprised of costs, plus
earnings on certain contracts in excess of contractual billings on such
contracts. Cash received in excess of costs incurred is classified as deferred
revenue.

INCOME TAXES

    Income taxes are accounted for using an asset and liability approach that
requires the recognition of taxes payable or refundable for the current year and
deferred tax liabilities and assets for the future tax consequences of events
that have been recognized in the Company's financial statements or tax returns.
The measurement of current and deferred tax liabilities and assets are based on
provisions of the enacted tax law; the effects of future changes in tax laws or
rates are not anticipated. The measurement of deferred tax assets is reduced, if
necessary, by the amount of any tax benefits that, based on available evidence,
are not expected to be realized.

             AS OF DECEMBER 31, 1996 AND 1997, AND OCTOBER 1, 1998

    In 1997, the Company had a line of credit which was collateralized by
substantially all of the assets of the Company. Under the terms of the line of
credit, borrowings were limited to 80 percent of qualified accounts receivable,
up to a maximum borrowing of $250,000. Interest on the outstanding balance was
calculated as the bank's prime rate of interest plus one and one-half percent.
As of December 31, 1997, there was no amount outstanding under the line of
credit. The agreement expired in May 1998.

    The note payable issued to the former shareholder related to the
reacquisition of 1,250,000 shares of common stock. The note was paid in full in
February 1998.

    The bank note payable contained certain restrictions on capital
expenditures, the incurrence of additional indebtedness, payment of cash
dividends and treasury stock transactions. This bank borrowing was paid in full
during February 1998.

7.  RETIREMENT PLAN:

    The Company maintains a retirement plan under the provisions of section
401(k) of the Internal Revenue Code. The plan was adopted January 1, 1997. The
Plan provides for contributions by employees and by the Company. Participants
may contribute up to 15 percent of their compensation, subject to statutory
limits. The Company's contribution is discretionary and is determined by its
Board of Directors. Company contributions vest immediately. Company
contributions totaled $32,000, and $40,000 for the year ended December 31, 1997,
and for the period from January 1, 1998 to October 1, 1998, respectively.
Effective February 1,1999, NMP employees are covered by the AppNet 401(k) plan.

8.  EMPLOYEE STOCK OPTION PLAN:

    On December 31, 1997, the Company adopted a stock option plan for employees,
directors, and consultants of the Company. Options expire no later than ten
years from the date of the grant or when employment ceases, whichever comes
first. The maximum number of shares of common stock which may be issued pursuant
to the stock option plan was 714,290.

    The stock option plan is accounted for under APB Opinion No. 25 and no
compensation has been recognized for the plan. Had compensation cost for the
plan been determined based on the estimated fair value of the options at the
grant dates consistent with the method of SFAS No. 123, the effect to pro forma
net income would have been approximately $7,000 and $91,000, for the year ended
December 31, 1997, and for the period from January 1, 1998 to October 1, 1998,
respectively. The weighted average fair value of the options granted during
1997, and during the period from January 1, 1998 to October 1, 1998, is
estimated to be $.03, and $.22, respectively, per option assuming the following:
dividend yield of 0 percent, risk-free interest rate ranging from 5.40 to 6.00
percent, volatility of 0 percent, and an expected term of the options of 5
years.

the end of each period are determined using the currently enacted tax rates to
apply to taxable income in the period in which the deferred tax asset or
liability is expected to be settled or realized.

reversal of deferred tax liabilities, projected future taxable income, and tax
planning strategies in making this assessment. For the year ended December 31,
1996, management determined that the deferred tax asset would be realized and
decreased the valuation allowance by $53,000. For the period

                         NOTES TO FINANCIAL STATEMENTS

                DECEMBER 31, 1996 AND 1997, AND OCTOBER 11, 1998

1.  BUSINESS DESCRIPTION:

    Century Computing, Inc. ("Century" or the "Company") was incorporated in
1979, under the laws of the state of Delaware. Century is a government
contractor that provides systems integration and processing services to improve
clients' business processes, including networking and data communications,
computer and Internet security, image processing, graphical user interfacing and
object-oriented design and development. Century is headquartered in Laurel,
Maryland, and operates primarily in the United States.

    On October 11, 1998, all of the issued and outstanding stock of the Company
was acquired by AppNet Systems, Inc. ("AppNet").

    There are significant risks associated with the Company, including the
subjectivity of the Company's services to rapid technological changes,
government regulations and the Year 2000 issue.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES:

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of revenues and expenses during the reporting
period. Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS

    The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost, net of accumulated depreciation
and amortization. Depreciation and amortization are computed over the estimated
useful lives of the related assets, as follows:

<TABLE>
<S>                                                        <C>
Computers, equipment and software........................  three to five
                                                           years
Furniture and fixtures...................................  seven years
</TABLE>

    Purchased software and third-party costs incurred to develop software for
internal use are capitalized and amortized principally over five years.
Leasehold improvements are amortized over the lesser of the estimated useful
life of the asset or the remaining lease term.

    In accordance with Statement of Financial Accounting Standards ("SFAS") No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of," the Company reviews its recorded long-lived assets
for impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                DECEMBER 31, 1996 AND 1997, AND OCTOBER 11, 1998

SOFTWARE DEVELOPMENT COSTS

    The Company has capitalized costs related to the development of certain
software products. In accordance with SFAS No. 86, "Accounting for the Costs of
Computer Software to Be Sold, Leased, or Otherwise Marketed," capitalization of
costs begins when technological feasibility has been established and ends when
the product is available for general release to customers. Amortization has been
computed and recognized based on the products' estimated economic lives of two
years. Capitalized costs and amortization periods are management's estimates and
may have to be modified due to inherent technological changes in software
development.

FAIR VALUE OF FINANCIAL INSTRUMENTS

    The Company's financial instruments consist primarily of cash, marketable
securities, accounts receivable, short-term borrowings and accounts payable. In
management's opinion, the carrying amounts of these financial instruments
approximated their fair values at December 31, 1996 and 1997, and October 11,
1998.

STOCK-BASED COMPENSATION

    The Company accounts for its stock-based employee compensation arrangements
using the intrinsic value method in accordance with provisions of Accounting
Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to
Employees," and complies with the disclosure provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation." Under APB Opinion No. 25,
compensation cost is recognized based on the difference, if any, on the date of
grant between the fair value of the Company's stock and the amount an employee
must pay to acquire the stock.

REVENUE RECOGNITION

    Revenues from time and material contracts are recognized based on fixed
hourly rates for direct labor hours expended. Revenues from fixed-price
contracts are recognized on the percentage-of-completion method, with costs and
estimated profits recorded as work is performed. Revenues from
cost-plus-fixed-fee contracts are recognized on the basis of direct costs, plus
indirect costs incurred, plus a fixed profit percentage.

    Cost of revenues includes all direct material and labor costs related to
contract performance and does not include any related depreciation expense.
Provisions for estimated losses on uncompleted contracts are made in the period
in which such losses are determined. Changes in contract performance and
estimated profitability, including final contract settlements, may result in
revisions to costs and income and are recognized in the period in which the
revisions are determined. Unbilled receivables on contracts are comprised of
costs, plus earnings on certain contracts in excess of contractual billings on
such contracts.

    Revenues from software sales are recognized when the related product is
sold, provided no significant vendor obligations remain.

BUSINESS CONCENTRATION AND CREDIT RISK

    Revenues for the years ended December 31, 1996 and 1997 and for the period
from January 1, 1998 through October 11, 1998, were concentrated with 45, 74 and
62 percent of agencies of the United States Government, respectively.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                DECEMBER 31, 1996 AND 1997, AND OCTOBER 11, 1998

    Billed accounts receivable and unbilled accounts receivable as of December
31, 1996 and 1997, and October 11, 1998, were concentrated with 56, 78 and 55
percent and 51, 78 and 50 percent of agencies of the United States Government,
respectively.

INCOME TAXES

    Income taxes are accounted for using an asset and liability approach that
requires the recognition of taxes payable or refundable for the current year and
deferred tax liabilities and assets for the future tax consequences of events
that have been recognized in the Company's financial statements or tax returns.
The measurement of current and deferred tax liabilities and assets are based on
provisions of the enacted tax law; the effects of future changes in tax laws or
rates are not anticipated. The measurement of deferred tax assets is reduced, if
necessary, by the amount of any tax benefits that, based on available evidence,
are not expected to be realized.

RECENT ACCOUNTING PRONOUNCEMENTS

    In March 1998, AIPCA issued Statement of Position 98-4 ("SOP 98-4"),
"Deferral of the Effective Date of a Provision of SOP 97-2." SOP 98-4 defers for
one year the application of certain provisions of Statement of Position 97-2
("SOP 97-2"), "Software Revenue Recognition." The Company does not expect the
adoption of these standards to have a material effect on the Company's results
of operations, financial position, or cash flows.

RECLASSIFICATIONS

    Certain amounts from the prior year financial statements have been
reclassified to conform with the current presentation.

which was secured by the accounts receivable of the Company. Under the terms of
the line of credit, borrowings were available up to a maximum borrowing of
$1,500,000. Interest on the outstanding balance was calculated at the bank's
prime rate plus one-half of one percent per annum, payable monthly. As of
December 31, 1996 and 1997, and October 11, 1998, there were no outstanding

$379,000, payable in three annual installments in January 1996, 1997 and 1998.
The Company placed $252,000 into an interest bearing escrow account during 1995
to satisfy the first two annual payments. The remaining balance was placed into
the escrow account during 1996. As of December 31, 1996 and 1997, and for the
period ended October 11, 1998, there was no outstanding balance on the note
payable.

10. RETIREMENT PLAN:

    The Company maintains a profit-sharing and retirement plan under the
provisions of section 401(k) of the Internal Revenue Code. The Plan provides for
contributions by employees and a discretionary contribution by the Company. The
plan is for the benefit of all employees who have attained the age of 21.
Participants may contribute up to 15 percent of their compensation, subject to
statutory limits. Employee contributions are fully vested. The Company's
contribution is discretionary and is determined by its Board of Directors.
Company contributions vest twenty percent per year over the five years, after
the first year. Company contributions totaled $125,000, $182,000 and $170,000
for the years ended December 31, 1996 and 1997, and for the period from January
1, 1998 to October 11, 1998, respectively.

    Effective February 1, 1999, Century's employees are covered by AppNet's

Class B stock or selling their Class A voting stock back to the Company. The
activity related to this program is presented in the statement of stockholders'
equity as stock conversion.

12. EMPLOYEE STOCK OPTION PLAN:

    The Company maintained a stock option plan for key employees. The issued
options expire no later than ten years from the date of the grant or when
employment ceases, whichever comes first.

    Options granted under the plan are accounted for pursuant to APB Opinion No.
25, "Accounting for Stock Issued to Employees," and no compensation has been
recognized for the plan. Had compensation cost for the plan been determined
based on the estimated fair value of the options at the grant dates consistent
with the method of SFAS No. 123, pro forma net income (loss) would have been
approximately $354,000, $844,000 and $380,000 for the years ended December 31,
1996 and 1997, and for the period from January 1, 1998 to October 11, 1998. The
weighted-average fair value of the options granted during 1996, 1997, and during
the period from January 1, 1998 to October 11, 1998, is estimated to be $5.58,
$5.50 and $5.84, respectively, per option. All stock options were granted at
fair market value at the date of grant.

    The following summarizes option activity during 1996, 1997 and for the
period from January 1, 1998 to October 11, 1998:

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Research & Planning, Inc.:

    We have audited the accompanying balance sheets of Research & Planning, Inc.
(a Massachusetts corporation), as of December 31, 1996 and 1997, and October 19,
1998, and the related statements of operations, stockholders' equity, and cash
flows for the years ended December 31, 1996 and 1997, and for the period from
January 1, 1998 to October 19, 1998. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the Company as of December
31, 1996 and 1997, and October 19, 1998, and the results of its operations and
its cash flows for the years ended December 31, 1996 and 1997, and for the
period from January 1, 1998 to October 19, 1998 in conformity with generally
accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

                DECEMBER 31, 1996 AND 1997, AND OCTOBER 19, 1998

1.  BUSINESS DESCRIPTION:

    Research & Planning, Inc. ("R&P" or the "Company") was incorporated in 1968,
under the laws of the state of Massachusetts. R&P is an information technology
services company providing Enterprise Resource Planning integration and support,
data warehousing, decision support applications and business-to-business
electronic commerce solutions. R&P is headquartered in Cambridge, Massachusetts
and operates primarily in the United States.

    On October 20, 1998, all of the issued and outstanding stock of the Company
was acquired by AppNet Systems, Inc. ("AppNet"). The Company incurred $99,000 of
expenses in conjunction with the sale to AppNet for accounting and consulting
fees. This has been classified in other expenses in the accompanying statements
of operations.

    There are significant risks associated with the Company, including the
subjectivity of the Company's services to rapid technological change and the
Year 2000 issue.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES:

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of revenues and expenses during the reporting
period. Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS

    The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost, net of accumulated depreciation
and amortization. Depreciation and amortization are computed using the
straight-line method over the estimated useful lives of the related assets, as
follows:

<TABLE>
<S>                                                                <C>
                                                                   five
Computers, equipment and software................................  years
                                                                   five
Furniture and fixtures...........................................  years
</TABLE>

    Purchased software is capitalized and amortized principally over five years.
Leasehold improvements are amortized over the lesser of the estimated useful
life of the asset or the remaining lease term.

    In accordance with Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of," the Company reviews its recorded long-lived assets for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                DECEMBER 31, 1996 AND 1997, AND OCTOBER 19, 1998

FAIR VALUE OF FINANCIAL INSTRUMENTS

    The Company's financial instruments consist primarily of cash and cash
equivalents, accounts receivable, accounts payable and short-term borrowings. In
management's opinion, the carrying amounts of these financial instruments
approximated their fair values at December 31, 1996 and 1997, and October 19,
1998.

REVENUE RECOGNITION

    Revenues pursuant to fixed-fee contracts are recognized on the
percentage-of-completion method with costs and estimated profits recorded as
work is performed. Revenues from time and material contracts are recognized
based on fixed hourly rates for direct labor expended.

    Cost of revenues includes all direct material and labor costs related to
contract performance and does not include any related depreciation expense.

    Provisions for estimated losses on uncompleted contracts are made on a
contract by contract basis and are recognized in the period in which such losses
are determined. Changes in contract performance and estimated profitability,
including final contract settlements, may result in revisions to costs and
income and are recognized in the period in which revisions are determined.
Unbilled receivables on contracts are comprised of costs, plus earnings on
certain contracts in excess of contractual billings on such contracts.

BUSINESS CONCENTRATION AND CREDIT RISK

    The following table summarizes the revenues and accounts receivable from
clients in excess of 10% of total revenues and accounts receivable:

INCOME TAXES

    The Company, with the consent of its shareholders, has elected to be taxed
pursuant to Subchapter S of the Internal Revenue Code (an "S Corporation"). In
lieu of corporate income taxes, the shareholders of an S corporation are taxed
on their proportionate share of the Company's taxable income. Therefore, no
provision for federal income taxes has been included in the accompanying
financial statements.

RECENT ACCOUNTING PRONOUNCEMENTS

    In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position 98-1 ("SOP 98-1"), "Accounting for the
Cost of Computer Software Developed or Obtained for Internal Use". SOP 98-1 is
effective for financial statements for years beginning after December 15, 1998.
SOP 98-1 provides guidance on accounting for computer software developed or
obtained for internal use, including the requirement to capitalize specified
costs and the amortization of such costs. The Company does not expect the
adoption of this standard to have a material effect on the Company's
capitalization policy.

reasonable assurance about whether the financial statements are free of material

                         NOTES TO FINANCIAL STATEMENTS

                    DECEMBER 31, 1997 AND DECEMBER 13, 1998

1.  BUSINESS DESCRIPTION:

    The Kodiak Group, Inc. ("Kodiak" or the "Company") was incorporated in 1994,
under the laws of the state of Massachusetts. Kodiak is an electronic commerce
services company which provides electronic data interchange ("EDI") integration
and processing services to clients who are looking to create, maintain or expand
their EDI systems. Kodiak is headquartered in Pittsfield, Massachusetts and
operates primarily in the Northeast.

    On December 13, 1998, all of the issued and outstanding stock of the Company
was acquired by AppNet Systems, Inc. ("AppNet").

    There are significant risks associated with the Company, including the
subjectivity of the Company's services to rapid technological change, government
regulations and the Year 2000 issue.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES:

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of revenues and expenses during the reporting
period. Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS

    The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost, net of accumulated depreciation
and amortization. Depreciation and amortization are computed using the
straight-line method over the estimated useful lives of the related assets, as
follows:

<TABLE>
<S>                                                        <C>
                                                           three to five
Computers, equipment and software........................  years
Furniture and fixtures...................................  five years
</TABLE>

    Purchased software and third-party costs incurred to develop software for
internal use are capitalized and amortized principally over three years.
Leasehold improvements are amortized over the lesser of the estimated useful
life of the asset or the remaining lease term.

    In accordance with Statement of Financial Accounting Standards ("SFAS") No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of," the Company reviews its recorded long-lived assets
for impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                    DECEMBER 31, 1997 AND DECEMBER 13, 1998

SOFTWARE DEVELOPMENT COSTS

    The Company has capitalized costs related to the development of certain
software products. In accordance with SFAS No. 86, "Accounting for the Costs of
Computer Software to Be Sold, Leased, or Otherwise Marketed," capitalization of
costs begins when technological feasibility has been established and ends when
the product is available for general release to customers. Amortization will be
computed and recognized based on the products' estimated economic lives of three
years. Capitalized costs and amortization periods are management's estimates and
may have to be modified due to inherent technological changes in software
development.

FAIR VALUE OF FINANCIAL INSTRUMENTS

    The Company's financial instruments consist primarily of cash and cash
equivalents, accounts receivable, accounts payable, and capital lease
obligations. In management's opinion, the carrying amounts of these financial
instruments approximated their fair values at December 31, 1997, and December
13, 1998.

REVENUE RECOGNITION

    Revenues from time and material contracts are recognized based on fixed
hourly rates for direct labor hours expended. Revenues from fixed-price
contracts are recognized on the percentage-of-
completion method, with costs and estimated profits recorded as work is
performed.

    Cost of revenues includes all direct material and labor costs related to
contract performance and does not include any related depreciation expense.
Provisions for estimated losses on uncompleted contracts are made in the period
in which such losses are determined. Changes in contract performance and
estimated profitability, including final contract settlements, may result in
revisions to costs and income and are recognized in the period in which the
revisions are determined. Unbilled receivables on contracts are comprised of
costs, plus earnings on certain contracts in excess of contractual billings on
such contracts. Cash received in excess of costs incurred is classified as
deferred revenue.

    Revenues from software sales are recognized when the related product is
sold, provided no significant vendor obligations remain.

BUSINESS CONCENTRATION AND CREDIT RISK

    The following table summarizes the revenues and accounts receivable from
clients in excess of 10% of total revenues and accounts receivable:

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                    DECEMBER 31, 1997 AND DECEMBER 13, 1998

INCOME TAXES

    The Company, with the consent of its shareholders, has elected to be taxed
pursuant to subchapter S of the Internal Revenue Code (an "S corporation"). In
lieu of corporation income taxes, the shareholders of an S corporation are taxed
on their proportionate share of the Company's taxable income. Therefore, no
provision for federal income taxes has been included in the accompanying
financial statements.

RECENT ACCOUNTING PRONOUNCEMENTS

    In March 1998, AIPCA issued Statement of Position 98-4 ("SOP 98-4"),
"Deferral of the Effective Date of a Provision of SOP 97-2." SOP 98-4 defers for
one year the application of certain provisions of Statement of Position 97-2
("SOP 97-2"), "Software Revenue Recognition." Different informal and
unauthoritative interpretations of certain provisions of SOP 97-2 have arisen
and, as a result, the AICPA is deliberating amendments to SOP 97-2, so it can
issue interpretations regarding the applicability and the method of application
of those provisions. The Company does not expect the adoption of this standard
to have a material effect on the Company's results of operations, financial
position, or cash flows.

                         NOTES TO FINANCIAL STATEMENTS

                       DECEMBER 31, 1996, 1997, AND 1998

1.  BUSINESS DESCRIPTION:

    i33 Communications Corporation ("i33" or the "Company") was incorporated in
January 1996, under the laws of the state of Delaware. The Company is an
interactive agency specializing in strategy, design, technology and online
advertising management for mid-sized to large companies. Revenues are generated
from web site design and development, online media buying and planning, online
advertising management, site audits, web publishing and project management
tools, custom application and database development and hosting services. i33 is
headquartered and operates primarily in New York.

    On January 8, 1999, all of the issued and outstanding stock of the Company
was acquired by AppNet Systems, Inc. The Company incurred $35,000 in consulting
fees in conjunction with the sale to AppNet. This has been classified as other
expense in the accompanying statements of operations.

    There are significant risks associated with the Company, including the
subjectivity of the Company's services to rapid technological change and the
Year 2000 issue.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES:

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of revenues and expenses during the reporting
period. Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS

    The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost, net of accumulated depreciation
and amortization. Depreciation and amortization are computed using the
straight-line method over the estimated useful lives of the related assets, as
follows:

<TABLE>
<S>                                                              <C>
Computer equipment.............................................  five years
                                                                 seven
Furniture and fixtures.........................................  years
</TABLE>

    Purchased software for internal use is capitalized and amortized principally
over three years. Leasehold improvements are amortized over the lesser of the
estimated useful life of the asset or the remaining lease term.

    In accordance with Statement of Financial Accounting Standards No. 121
("SFAS"), "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of," the Company reviews its recorded long-lived assets
for impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                       DECEMBER 31, 1996, 1997, AND 1998

FAIR VALUE OF FINANCIAL INSTRUMENTS

    The Company's financial instruments consist primarily of cash and cash
equivalents, accounts receivable, accounts payable, short-term borrowings, and
capital lease obligations. In management's opinion, the carrying amounts of
these financial instruments approximated their fair values at December 31, 1996,
1997, and 1998.

REVENUE RECOGNITION

    Revenues from time and material contracts are recognized based on fixed
hourly rates for direct labor hours expended. Revenues from fixed-price
contracts are recognized on the percentage-of-
completion method, with costs and estimated profits recorded as work is
performed. Revenues from fixed-price advertising contracts in which the Company
delivers advertising impressions for its customers on third-party websites are
recognized ratably over the period the advertising impressions are delivered. In
accordance with industry practice, the cost of third-party advertising placed by
the Company on behalf of its clients is offset against the related customer
reimbursement in the accompanying statements of operations.

    Cost of revenues includes all direct material and labor costs related to
contract performance and does not include any related depreciation expense.
Provisions for estimated losses on uncompleted contracts are made in the period
in which such losses are determined. Changes in contract performance and
estimated profitability, including final contract settlements, may result in
revisions to costs and income and are recognized in the period in which the
revisions are determined. Unbilled receivables on contracts are comprised of
costs, plus earnings on certain contracts in excess of contractual billings on
such contracts. Cash received in excess of costs incurred is classified as
deferred revenue.

BUSINESS CONCENTRATION AND CREDIT RISK

    The following table summarizes the revenues and receivables from clients in
excess of 10% of total revenues and receivables:

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                       DECEMBER 31, 1996, 1997, AND 1998

INCOME TAXES

    In 1996, the Company was taxed as a C corporation. As such, income taxes are
accounted for using an asset and liability approach that requires the
recognition of taxes payable or refundable for the current year and deferred tax
liabilities and assets for the future tax consequences of events that have been
recognized in the Company's financial statements or tax returns. The measurement
of current and deferred tax liabilities and assets are based on provisions of
the enacted tax law; the effects of future changes in tax laws or rates are not
anticipated. The measurement of deferred tax assets is reduced, if necessary, by
the amount of any tax benefits that, based on available evidence, are not
expected to be realized.

    In 1997 and 1998, the Company, with the consent of its shareholders, has
elected to be taxed pursuant to subchapter S of the Internal Revenue Code ("an S
corporation"). In lieu of corporation income taxes, the shareholders of an S
corporation are taxed on their proportionate share of the Company's taxable
income. Therefore, no provision for federal income taxes has been included in
the accompanying financial statements. The Company is subject to state and city
income taxes based on the Company's taxable income and alternative minimum tax.
The recorded tax provision for 1997 and 1998 relates to these state and city
taxes. The significant components of differences between income reported for
financial statement purposes and income reported for tax purposes relates to tax
basis adjustments for accounts receivable, payroll and corporate tax
liabilities.

                         NOTES TO FINANCIAL STATEMENTS

                               DECEMBER 31, 1998

1.  BUSINESS DESCRIPTION:

    Salzinger & Company ("Salzinger" or the "Company") was incorporated in 1995,
under the laws of the state of Virginia. Salzinger is a consulting company
providing business-level strategic consulting in website marketing strategy
development, planning and implementation. It is headquartered in Virginia and
operates primarily in the Northeast, with some international clients.

    On March 15, 1999, certain assets of the Company were acquired by AppNet
Systems, Inc.

    There are significant risks associated with the Company, including the
subjectivity of the Company's services to rapid technological change and the
Year 2000 issue.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES:

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of revenues and expenses during the reporting
period. Actual results could differ from those estimates.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost, net of accumulated depreciation
and amortization. Depreciation and amortization are computed using the
straight-line method over the estimated useful lives of the related assets, as
follows:

<TABLE>
<S>                                                               <C>
                                                                  three
Computer equipment and software.................................  years
Furniture and fixtures..........................................  five years
Automobile......................................................  five years
</TABLE>

    Purchased software is capitalized and amortized principally over three
years.

    In accordance with Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of," the Company reviews its recorded long-lived assets for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable.

FAIR VALUE OF FINANCIAL INSTRUMENTS

    The Company's financial instruments consist primarily of cash, accounts
receivable, accounts payable and short-term borrowing. In management's opinion,
the carrying amounts of these financial instruments approximated their fair
values at December 31, 1998.

REVENUE RECOGNITION

    Revenues from time and material contracts are recognized based on fixed
hourly rates for direct labor hours expended. The Company also enters into
arrangements in which a portion of its fee is based on the successful completion
of a transaction. Revenue under these contracts is recognized when

the transaction has closed and the Company is due its success fee. Included
within revenues in the accompanying statement of operations are success fees of
approximately $730,000.

    Cost of revenues includes all direct material and labor costs related to
contract performance and does not include any related depreciation expense.
Unbilled receivables on contracts are comprised of costs, plus earnings on
certain contracts in excess of contractual billings on such contracts. Cash
received in excess of costs incurred is classified as deferred revenue.

BUSINESS CONCENTRATION AND CREDIT RISK

    The following table summarizes the revenues and accounts receivable from
clients in excess of 10% of total revenues and accounts receivable:

1.  BUSINESS DESCRIPTION:

    Internet Outfitters, Inc. ("IO" or the "Company") was incorporated in 1994
under the laws of the state of California. IO is an information technology
services company providing internet and web-based solutions designed to improve
clients' business processes, including strategy consulting, applications
development, electronic commerce, systems design, technology development,
integration, and operation. The Company is headquartered in Santa Monica,
California and operates primarily in the western region of the United States.

    On March 22, 1999, the Company entered into a Stock Purchase Agreement with
AppNet Systems, Inc. ("AppNet"). The transaction was completed on March 26,
1999.

    There are significant risks associated with the Company, including the
subjectivity of the Company's services to rapid technological change and the
Year 2000 issue.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES:

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of revenues and expenses during the reporting
period. Actual results could differ from those estimates.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost, net of accumulated depreciation
and amortization. Depreciation and amortization are computed using the
straight-line method over the estimated useful lives of the related assets, as
follows:

<TABLE>
<S>                                                        <C>
                                                           three to five
Computer equipment and software..........................  years
Furniture and fixtures...................................  seven years
</TABLE>

    Purchased software and third-party costs incurred to develop software for
internal use are capitalized and amortized principally over three years.

    In accordance with Statement of Financial Accounting Standards ("SFAS") No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of," the Company reviews its recorded long-lived assets
for impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable.

FAIR VALUE OF FINANCIAL INSTRUMENTS

    The Company's financial instruments consist primarily of cash, accounts
receivable, accounts payable, long-term debt and capital lease obligations. In
management's opinion, the carrying amounts of these financial instruments
approximated their fair values at December 31, 1998.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                               DECEMBER 31, 1998

STOCK-BASED COMPENSATION

    The Company accounts for stock-based employee compensation arrangements
using the intrinsic value method in accordance with provisions of Accounting
Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to
Employees," and complies with the disclosure provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation." Under APB Opinion No. 25,
compensation cost is recognized based on the difference, if any, on the date of
grant between the fair value of the Company's stock and the amount an employee
must pay to acquire the stock.

REVENUE RECOGNITION

    Revenues from time and material contracts are recognized based on fixed
hourly rates for direct labor hours expended. Revenues from fixed-price
contracts are recognized on the percentage-of-
']completion method, with costs and estimated profits recorded as work is
performed. Revenues from fixed-price advertising contracts in which the Company
delivers advertising impressions for its customers on third-party websites are
recognized ratably over the period the advertising impressions are delivered. In
accordance with industry practice, the cost of third party advertising placed by
the Company on behalf of its clients is offset against the related customer
reimbursement in the accompanying statement of operations. Revenues from
cost-plus-fixed-fee contracts are recognized on the basis of direct costs plus
indirect costs incurred plus a fixed profit percentage.

    Costs of revenues includes all direct material and labor costs related to
contract performance and does not include any related depreciation expense.
Provisions for estimated losses on uncompleted contracts are made in the period
in which such losses are determined. Changes in contract performance and
estimated profitability, including final contract settlements, may result in
revisions to costs and income and are recognized in the period in which the
revisions are determined. Unbilled revenues on contracts are comprised of costs,
plus earnings on certain contracts in excess of contractual billings on such
contracts. Cash received in excess of costs incurred is classified as deferred
revenue.

BUSINESS CONCENTRATION AND CREDIT RISK

    The following table summarizes the revenues and receivables from clients in
excess of 10% of total revenues and receivables:

INCOME TAXES

    Income taxes are accounted for using an asset and liability approach that
requires the recognition of taxes payable or refundable for the current year and
deferred tax liabilities and assets for the future tax consequences of events
that have been recognized in the Company's financial statements or tax returns.
The measurement of current and deferred tax assets and liabilities are based on
provisions of

                                     F-125

the enacted tax law; the effects of future changes in tax laws or rates are not
anticipated. The measurement of deferred tax assets is reduced, if necessary, by
the amount of any tax benefits that, based on available evidence, are not
expected to be realized.

3.  ACCOUNTS RECEIVABLE:

    Accounts receivable consists of the following as of December 31, 1998:

<TABLE>
<S>                                                                 <C>

</TABLE>

    In February 1998, the Company entered into a factoring agreement to sell,
with recourse, on an ongoing basis, certain accounts receivable to a third
party. Collections received on these accounts may be replaced by new receivables
in order to maintain the aggregate outstanding balance. Proceeds from the sale
of receivables are collateralized by substantially all of the assets of the
Company. At no time may the total accounts receivable factored exceed $350,000.
Fees associated with these transactions are included in interest expense in the
accompanying statement of operations. The factoring agreement has an initial
term of one year and is renewed from year to year thereafter unless terminated
by either party.

    As of December 31, 1998, accounts receivable totaling $224,000 had been
pledged as collateral against this asset-based borrowing.

    In accordance with SFAS No. 125, "Accounting for Transfers and Servicing of
Financial Assets and Extinguishments of Liabilities," the Company's accounts
receivable program will be accounted for as a secured borrowing. The receivables
and the corresponding debt are included as an asset and liability, respectively,
on the accompanying balance sheet.

8.  EMPLOYEE STOCK OPTION PLAN:

    The Company has a stock option plan for key employees. Options expire no
later than ten years from the date of the grant or when employment ceases,
whichever comes first. One-third of the granted options vest on the grant date.
The remaining options vest ratably on the first and second anniversaries of the
date of grant. The maximum number of shares of common stock that may be issued
pursuant to the stock option plan is 5,000,000 shares at December 31, 1998.

    The stock option plan is accounted for under APB Opinion No. 25, "Accounting
for Stock Issued to Employees." Had compensation cost for the plan been
determined based on the estimated fair value of the options at the grant dates
consistent with the method of SFAS No. 123, pro forma net loss would have been
approximately $289,000 for the year ended December 31, 1998. The weighted
average fair value of the options granted during 1998 is estimated to be $0.84
per option assuming the following: dividend yield of 0 percent, risk-free
interest rate of 5 percent and an expected term of the options of 3.4 years.

LITIGATION AND CLAIMS

    In 1998, one of the Company's suppliers informed IO that it believed the
Company had caused a third-party client of the Company to enter into an
incorrect license for a supplier's software. The supplier asserted that the
correct license required additional payments of approximately $2,200,000 in
license fees and technical support fees. The Company denies any liability for
additional licensing fees. While the Company intends to vigorously contest any
claim by the supplier that additional fees are owed in connection with the third
party, the ultimate resolution of this matter cannot be determined at this time.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.


    AppNet's bylaws provide that AppNet shall indemnify to the fullest extent
authorized by the Delaware General Corporation Law, each person who is involved
in any litigation or other proceeding because such person is or was a director
or officer of AppNet, against all expense, loss or liability reasonably incurred
or suffered in connection therewith. AppNet's bylaws provide that a director or
officer may be paid expenses incurred in defending any proceeding in advance of
its final disposition upon receipt by AppNet of an undertaking, by or on behalf
of the director or officer, to repay all amounts so advanced if it is ultimately
determined that such director or officer is not entitled to indemnification.

    Section 145 of the Delaware General Corporation Law permits a corporation to
indemnify any director or officer of the corporation against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred in connection with any action, suit or proceeding brought by
reason of the fact that such person is or was a director or officer of the
corporation, if such person acted in good faith and in a manner that he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, if he had
no reason to believe his conduct was unlawful. In a derivative action, (I.E.,
one brought by or on behalf of the corporation), indemnification may be made
only for expenses, actually and reasonably incurred by any director or officer
in connection with the defense or settlement of such an action or suit, if such
person acted in good faith and in a manner that he reasonably believed to be in
or not opposed to the best interests of the corporation, except that no
indemnification shall be made if such person shall have been adjudged to be
liable to the corporation, unless and only to the extent that the court in which
the action or suit was brought shall determine that the defendant is fairly and
reasonably entitled to indemnity for such expenses despite such adjudication of
liability.

    Pursuant to Section 102(b)(7) of the Delaware General Corporation Law,
AppNet's certificate of incorporation eliminates the liability of a director to
the corporation or its stockholders for monetary damages for such breach of
fiduciary duty as a director, except for liabilities arising (a) from any breach
of the director's duty of loyalty to the corporation or its stockholders; (b)
from acts or omissions

                                      II-1
<PAGE>
not in good faith or which involve intentional misconduct or a knowing violation
of law; (c) under Section 174 of the Delaware General Corporation Law; or (d)
from any transaction from which the director derived an improper personal
benefit.

    AppNet intends to obtain primary and excess insurance policies insuring its
directors and officers and those of its subsidiaries against certain liabilities
they may incur in their capacity as directors and officers. Under such policies,
the insurer, on behalf of AppNet, may also pay amounts for which AppNet has
granted indemnification to the directors or officers.

    Additionally, reference is made to the Underwriting Agreement filed as
Exhibit 1.1 hereto, which provides for indemnification by the Underwriters of
AppNet, its directors and officers who sign the registration statement and
persons who control AppNet, under certain circumstances.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.

ITEM 17. UNDERTAKINGS.

    The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual reports pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

    Insofar as indemnification for liabilities arising under the Securities Act
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 payment by the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

    The undersigned registrant hereby undertakes that:

    (1) To provide to the Underwriters at the closing specified in the
underwriting agreement certificates in such denominations and registered in such
names as required by the Underwriters to permit proper delivery to each
purchaser.

    (2) For purposes of determining any liability under the Securities Act, the
information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424b(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.

    (3) For purposes of determining any liability under the Securities Act, each
post-effective amendment that contains a form of prospectus shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

                                   SIGNATURES


    Pursuant to the requirements of the Securities Act of 1933, the registrant
has duly caused this Amendment No. 3 to the registration statement to be signed
on its behalf by the undersigned, thereunto duly authorized, in the City of
Bethesda, State of Maryland, on May 28, 1999.

To AppNet Systems, Inc.:

    We have audited, in accordance with generally accepted auditing standards,
the consolidated financial statements of AppNet Systems, Inc. and the financial

respect to the matter discussed in Note 18, as to which the date is May   ,
1999) and February 5, 1999, respectively. Our audits were made for the purpose
of forming an opinion on the basic financial statements taken as a whole. The

financial statements. This schedule has been subjected to the auditing
procedures applied in the audit of the basic financial statements and, in our
opinion, fairly states in all material respects the financial data required to
be set forth therein in relation to the basic financial statements taken as a
whole.

by wire transfer (or by the return to the Buyer, at Sellers' Representative's
option, the equivalent number of shares of Buyer Common Stock (valued at $4.50
per share) equal to) the amount, if any, by which the amount of the AA
Determination is less than the Minimum Net Worth (less any deduction against the
Cash Portion of the Purchase Price as a result of the Closing Determination)
within ten (10) days after the AA Determination.

                  (n) Sellers' Representative.

                        (i) In order to administer efficiently (A) the
            implementation of the Agreement by the Sellers, (B) the waiver of

            Representative (A) to take all action necessary in connection with
            the implementation of the Agreement on behalf of the Sellers, the
            waiver of any condition to the obligations of the Sellers to

            of any dispute, (B) to give and receive all notices required to be

                        (iii) In the event that the Sellers' Representative
            dies, becomes legally incapacitated or resigns from such position,
            William Tiggertt III shall fill such vacancy and shall be deemed to
            be the Sellers' Representative for all purposes of this Agreement;
            however, no change in the Sellers' Representative shall be effective
            until Buyer is given notice of it by the Sellers.

                        (iv) All decisions and actions by the Sellers'
            Representative shall be binding upon all of the Sellers, and no
            Seller shall have the right to object, dissent, protest or otherwise
            contest the same, in the absence of fraud, gross negligence or
            willful misconduct of the Sellers' Representative.

                        (v) By their execution of this Agreement, the Sellers
            agree that: (A) Buyer shall be able to rely conclusively on the
            instructions and decisions of the Sellers' Representative as to any
            actions required or permitted to be taken by the Sellers or the
            Sellers' Representative hereunder, and no party hereunder shall have
            any cause of action against Buyer for action taken by Buyer in
            reliance upon the instructions or decisions of the Sellers'
            Representative; (B) all actions, decisions and instructions of the
            Sellers' Representative shall be conclusive and binding upon all of
            the Sellers; no Seller shall have any cause of action against Buyer
            or Sigma6 for any action taken or omitted to be taken, decision made
            or omitted to be made or any instruction given or omitted to be
            given by the Sellers' Representative; and no Seller shall have any
            cause of action against the Sellers' Representative for any action
            taken, decision made or instruction given by the Sellers'
            Representative under this Agreement, except for fraud, gross
            negligence or willful breach of this Agreement by the Sellers'
            Representative; (C) the Sellers' Representative shall be deemed to
            fulfill any fiduciary obligation to the Sellers so long as no Seller
            is adversely affected by any action or failure to act of the
            Sellers' Representative in a


                                      -13-
<PAGE>

            disproportionate measure compared to any other Seller; (D) remedies
            available at law for any breach of the provisions of this Section
            2(n) are inadequate; therefore, Buyer shall be entitled to temporary
            and permanent injunctive relief without the necessity of proving
            damages if Buyer brings an action to enforce the provisions of this
            Section 2(n); (E) the provisions of this Section 2(n) are
            independent and severable, shall constitute an irrevocable power of
            attorney, coupled with an interest and surviving death, granted by
            the Sellers to the Sellers' Representative and shall be binding upon
            the executors, heirs, legal representatives and successors of each
            Seller; and (F) all reasonable fees and expenses incurred by the
            Sellers' Representative shall be paid by the Sellers pro rata in
            proportion to their percentage interest in Sigma6 at Closing.

                  (o) Escrow Arrangements. Pursuant to the terms and conditions
of the Escrow Agreement to be entered into among the Sellers, Buyer and the
Escrow Agent, $250,000 of the Cash Portion of the Purchase Price shall be
delivered to the Escrow Agent at Closing in immediately available funds. Such
monies (which is hereinafter referred to as the "Escrow Sum") shall be held
pursuant to the terms of the Escrow Agreement to satisfy the amounts owing by
the Sellers to Buyer pursuant to the indemnification provisions of Article VIII
below. At the conclusion of the period ending on the eighteen month anniversary
of the Closing Date (such period being referred to herein as the "Escrow
Period"), any remaining portion of the Escrow Sum not theretofore paid to Buyer
in accordance with the terms of the Escrow Agreement or subject to a pending
claim under the Escrow Agreement and this Agreement shall be disbursed to the
Sellers. The Sellers and Buyer agree that each will execute and deliver such
reasonable instruments and documents as are furnished by any other party to
enable such furnishing party to receive those portions of the Escrow Sum to
which the furnishing party is entitled under the provisions of the Escrow
Agreement and this Agreement.

            3. Representations and Warranties Concerning the Transaction.

                  (a) Representations and Warranties of each Seller. Each Seller
individually represents and warrants to the Buyer as follows as of the date of
this Agreement and as of the Closing Date (as though made then and as though the
Closing Date were substituted for the date of this Agreement throughout this
Section 3(a)), except as set forth in Annex II attached hereto: provided,
however, that Annex II may be updated as of the Closing Date ("Updated
Disclosure Schedule") and if accepted by Buyer, the additional matters set forth
therein shall be exceptions hereto except as otherwise set forth in Article VIII
herein and Sellers shall not be liable for matters disclosed on Annex II or the
Updated Disclosure Schedule except as otherwise set forth in Article VIII
herein. Any reference to Annex II or the Disclosure Schedule shall mean as
modified by the Updated Disclosure Schedule.

                        (i) Authorization of Transaction. The Seller has full
            power and authority to execute and deliver this Agreement and the
            other agreements and documents executed in connection herewith and
            to perform its obligations hereunder and thereunder and this
            Agreement and such other agreements and documents have been duly
            executed and delivered by the Seller. This Agreement


                                      -14-
<PAGE>

            and such other agreements and documents constitute the valid and
            legally binding obligation of the Seller, enforceable in accordance
            with their terms and conditions, except that (A) such enforceability
            may be subject to bankruptcy, insolvency, reorganization, fraudulent
            conveyance, moratorium or other laws, decisions or equitable
            principles now or hereafter in effect relating to or affecting the
            enforcement of creditors' rights or debtors' obligations generally
            or non-competition arrangements, and to general equity principles,
            and (B) the remedy of specific performance and injunctive and other
            forms of equitable relief may be subject to equitable defenses and
            to the discretion of the court before which any proceeding therefor
            may be brought (the terms of clause (A) and (B) are sometimes
            collectively referred to as the "Equitable Exceptions"). The Seller
            need not give any notice to, make any filing with, or obtain any
            authorization, consent, or approval of any government or
            governmental agency in order to consummate the transactions
            contemplated by this Agreement (other than as provided for in
            Article 2 of this Agreement).

                        (ii) Noncontravention. Neither the execution and the
            delivery of this Agreement by the Seller, nor the consummation of
            the transactions contemplated hereby by the Seller, will (A) violate
            any statute, regulation, rule, judgment, order, decree, stipulation,
            injunction, charge, or other restriction of any government,
            governmental agency, or court to which the Seller is subject or (B)
            except as set forth in Section 3(a) of the Disclosure Schedule,
            conflict with, result in a breach of, constitute a default under,
            result in the acceleration of, create in any part the right to
            accelerate, terminate, modify, or cancel, or require any notice
            under any contract, lease, sublease, license, sublicense, franchise,
            permit, indenture, agreement or mortgage for borrowed money,
            instrument of indebtedness, Security Interest, or other arrangement
            to which the Seller is a party or by which it is bound or to which
            any of its assets is subject.

                        (iii) Broker's Fees. Seller has no Liability or
            obligation to pay any fees or commissions to any broker, finder, or
            agent with respect to the transactions contemplated by this
            Agreement for which the Buyer could become liable or obligated.

                        (iv) Investment. The Seller is not acquiring Buyer's
            Shares with a view to or for sale in connection with any
            distribution thereof within the meaning of the Securities Act.

                        (v) Sigma6 Shares. The Seller holds of record and owns
            beneficially the number of Sigma6 Common Shares and/or Sigma6
            Preferred Shares set forth next to its name in Section 4(b) of the
            Disclosure Schedule, and except as set forth in Section 4(b) of the
            Disclosure Schedule, such Sigma6 Shares are free and clear of any
            restrictions on transfer all of which have been terminated as of or
            prior to the Closing Date (other than any restrictions under the
            Securities Act and state securities laws), claims, Taxes, Security
            Interests, options, warrants, rights,


                                      -15-
<PAGE>

            contracts, calls, commitments, equities, and demands. Except as set
            forth in Section 4(b) of the Disclosure Schedule, the Seller is not
            a party to (or has otherwise waived all rights under) any option,
            warrant, right, contract, call, put, or other agreement or
            commitment providing for the disposition or acquisition of any
            capital stock of Sigma6 (other than this Agreement). The Seller is
            not a party to (or has otherwise terminated) any voting trust,
            proxy, or other agreement or understanding with respect to the
            voting of any capital stock of Sigma6.

                        (vi) Disclosure. The representations and warranties
            contained in this Section 3(a) as amended, modified and/or
            supplemented by Annex II do not contain any untrue statement of a
            fact or omit to state any Material (as defined) fact necessary in
            order to make the statements and information contained in this
            Section 3(a) not misleading that result in Adverse Consequences.

                  (b) Representations and Warranties of the Buyer and Newco. The
Buyer and Newco represent and warrant to the Sellers that the statements
contained in this Section 3(b) are correct and complete as of the date of this
Agreement and will be correct and complete as of the Closing Date (as though
made then and as though the Closing Date were substituted for the date of this
Agreement throughout this Section 3(b)), except as set forth in Annex III
attached hereto.

                        (i) Organization of the Buyer and Newco. Each of the
            Buyer and Newco is a corporation duly organized, validly existing,
            and in good standing under the laws of the jurisdiction of its
            incorporation. The Buyer has delivered to Sellers correct and
            complete copies of the charter and bylaws of Buyer and Newco (as
            amended to date). Neither Buyer nor Newco is in default under or in
            violation of its charter or bylaws.

                        (ii) Authorization of Transaction. Each of the Buyer and
            Newco has full power and authority (including full corporate power
            and authority) to execute and deliver this Agreement and the other
            agreements and documents executed in connection herewith and to
            perform its obligations hereunder and thereunder and this Agreement
            and such other documents have been duly executed and delivered by
            the Buyer and Newco. This Agreement and such other agreements and
            documents constitute the valid and legally binding obligation of the
            Buyer and Newco, enforceable in accordance with their terms and
            conditions except for the Equitable Exceptions. Neither the Buyer
            nor Newco needs to give any notice to, make any filing with, or
            obtain any authorization, consent, or approval of any government or
            governmental agency in order to consummate the transactions
            contemplated by this Agreement (other than as provided for in
            Article 2 of this Agreement).

                        (iii) Noncontravention. Neither the execution and the
            delivery of this Agreement by the Buyer or Newco, nor the
            consummation of the transactions contemplated hereby by the Buyer or
            Newco, will (A) violate any statute,


                                      -16-
<PAGE>

            regulation, rule, judgment, order, decree, stipulation, injunction,
            charge, or other restriction of any government, governmental agency,
            or court to which the Buyer is subject or any provision of its
            charter or bylaws or (B) conflict with, result in a breach of,
            constitute a default under, result in the acceleration of, create in
            any party the right to accelerate, terminate, modify, or cancel, or
            require any notice under any contract, lease, sublease, license,
            sublicense, franchise, permit, indenture, agreement or mortgage for
            borrowed money, instrument of indebtedness, Security Interest, or
            other arrangement to which the Buyer or Newco is a party or by which
            it is bound or to which any of its assets is subject and which has a
            Material adverse effect on Buyer.

                        (iv) Brokers' Fees. Neither Newco nor the Buyer has any
            Liability or obligation to pay any fees or commissions to any
            broker, finder, or agent with respect to the transactions
            contemplated by this Agreement for which the Sellers could become
            liable or obligated.

                        (v) Investment. Neither Newco nor the Buyer is acquiring
            Sigma6 Shares with a view to or for sale in connection with any
            distribution thereof within the meaning of the Securities Act.

            4. Representations and Warranties Concerning Sigma6. Sigma6 and the
      Sellers jointly and severally represent and warrant to the Buyer that,
      subject to the specific qualifications and limitations set forth herein,
      the statements contained in this Section 4 are correct and complete as of
      the date of this Agreement and will be correct and complete as of the
      Closing Date (as though made then and as though the Closing Date were
      substituted for the date of this Agreement throughout this Section 4),
      except as set forth in the Disclosure Schedule delivered by the Sellers to
      the Buyer on the date hereof and initialed by the Parties (the "Disclosure
      Schedule"). The Disclosure Schedule may be updated one or more times prior
      to the Closing Date. Any updated Disclosure Schedule shall be delivered at
      or before the Closing. In the event any such updated Disclosure Schedule
      indicates any Material adverse change from information previously provided
      to the Buyer, Buyer shall be entitled to terminate this Agreement (without
      any liability whatsoever to Sigma6) by written notice delivered to Sigma6
      following receipt of such updated Disclosure Schedule. An event or matter
      that causes any representation or warranty contained in this Section to be
      inaccurate, incorrect or false will not be deemed to be "Material," to
      have a "Material" change in or in respect of, to have a "Material" adverse
      effect or to be "Materially" affected unless the loss that may reasonably
      be expected to occur to Sigma6 with respect to such event or matter, when
      taken together with all other related losses that may reasonably be
      expected to occur to Sigma6 as a result of any such events or matters,
      would exceed $20,000 in the aggregate or unless such event or matter
      constitutes a criminal violation of law. For purposes of this paragraph,
      the word "loss" shall mean any and all direct or indirect payments,
      obligations, assessments, losses, losses of income, liabilities, costs and
      expenses paid or incurred; provided, however, that losses shall be net of
      any insurance proceeds entitled to be received from a nonaffiliated
      insurance company on account of such loss (after taking into account any
      cost incurred in obtaining such proceeds or any increases in insurance
      premiums as a direct result thereof). A Customer Contract or Agreement is
      "Material" if during either calendar year 1998


                                      -17-
<PAGE>

such Customer Contract or Agreement produced or is expected to produce $50,000
of Gross Revenues. Nothing in the Disclosure Schedule shall be deemed adequate
to disclose an exception to a representation or warranty made herein, however,
unless the Disclosure Schedule identifies the exception with reasonable
particularity and describes the relevant facts in reasonable detail as the
context requires. The Disclosure Schedule will be arranged in paragraphs
corresponding to the lettered and numbered paragraphs contained in this Section
4.

                  (a) Organization, Qualification, and Corporate Power. Sigma6
is a corporation duly organized, validly existing, and in good standing under
the laws of the jurisdiction of its incorporation. Except as disclosed in
Section 4(a) of the Disclosure Schedule, Sigma6 is duly authorized to conduct
business and is in good standing under the laws of the State of Michigan, which
is the only jurisdiction in which the nature of its businesses or the ownership
or leasing of its properties requires such qualification. Sigma6 has full
corporate power and authority to carry on the businesses in which it is engaged
and to own and use the properties owned and used by it; provided, however, that
for all properties used but not owned by Sigma6, such power and authority are
only to the extent that Sigma6 has the rights to use such properties (which
rights are sufficient to operate its Sigma6's Business). Section 4(a) of the
Disclosure Schedule lists the directors and officers of Sigma6. Sigma6 has
delivered to the Buyer correct and complete copies of the charter and bylaws of
Sigma6 (as amended to date). The minute books containing the records of meetings
and/or resolutions of the stockholders, the board of directors, and any
committees of the board of directors, the stock certificate books and the stock
record books of Sigma6 are correct and complete in all Material respects. Sigma6
is not in default under or in violation of any provision of its charter or
bylaws.

                  (b) Capitalization. The entire authorized capital stock of
Sigma6 consists of 50,000 shares of common stock, no par value, of which 20,000
are issued and outstanding, none are subject to issuance pursuant to vested
options, none are subject to issuance pursuant to unvested options and none are
reserved for issuance pursuant to future option grants. All of the issued and
outstanding Sigma6 Shares have been duly authorized, are validly issued, fully
paid, and nonassessable, and are held of record by the Sellers except as set
forth in Section 4(b)-1 of the Disclosure Schedule. Except as set forth in
Section 4(b)-2 of the Disclosure Schedule, there are no outstanding or
authorized options, warrants, rights, contracts, calls, puts, rights to
subscribe, conversion rights, or other agreements or commitments to which Sigma6
is a party or which are binding upon Sigma6 providing for the issuance,
disposition, or acquisition of any of its capital stock. Except as set forth in
Section 4(b)-3 of the Disclosure Schedule, there are no outstanding or
authorized stock appreciation, phantom stock, or similar rights with respect to
Sigma6. There are no voting trusts, proxies, or any other agreements or
understandings with respect to the voting of the capital stock of Sigma6.

                  (c) Noncontravention. Except as disclosed in Section 4(c) of
the Disclosure Schedule and solely as applicable to Sigma6, neither the
execution and the delivery of this Agreement, nor the consummation of the
transactions contemplated hereby, will (i) violate any statute, regulation,
rule, judgment, order, decree, stipulation, injunction, charge, or other
restriction of any government, governmental agency, or court to which Sigma6 is
subject or any provision of the charter or bylaws of Sigma6, except to the
extent any such violation does not or could not result


                                      -18-
<PAGE>

in a Material adverse effect on Sigma6, or (ii) conflict with, result in a
breach of, constitute a default under, result in the acceleration of, create in
any party the right to accelerate, terminate, modify, or cancel, or require any
notice under any contract, lease, sublease, license, sublicense, franchise,
permit, indenture, agreement or mortgage for borrowed money, instrument of
indebtedness, Security Interest on the property owned or leased by Sigma6, or
other arrangement to which Sigma6 is a party or by which it is bound or to which
any of its assets is subject (or result in the imposition of any Security
Interest upon any of its assets). Except as set forth on Section 4(c) of the
Disclosure Schedule, Sigma6 does not need to give any notice to, make any filing
with, or obtain any authorization, consent, or approval of any government or
governmental agency in order for the Parties to consummate the transactions
contemplated by this Agreement.

                  (d) Subsidiaries. Sigma6 has no Subsidiaries.

                  (e) Financial Statements. Attached hereto as Exhibit B are the
following Sigma6 financial statements (collectively the "Financial Statements"):
audited balance sheet and statement of income, changes in stockholder's equity,
and cash flow as of and for the fiscal years ended December 31, 1996 and 1997
(the most recent of such dates to be referred to as the "Most Recent Fiscal Year
End") and an unaudited consolidated balance sheet and statement of income,

            Disclosure Schedule, there has not been any other occurrence, event,

                  (g) Undisclosed Liabilities. Except as set forth on Section

there is no Basis for any present or future charge, complaint, action, suit,
proceeding, hearing, investigation, claim, or demand against Sigma6 giving rise

Standards Act of 1938, as amended and the rules and regulations promulgated
thereunder) which is individually in excess of $15,000, except for (i)
Liabilities set forth on the face of the Stub Period End Balance Sheet, (ii)
Liabilities described on Schedule 4(g) of the Disclosure Schedule and (iii)
Liabilities which have arisen after the Stub Period End in the Ordinary Course
of Business (none of which relates to any breach of contract, breach of
warranty, tort, infringement, or violation of law or arose out of any charge,
complaint, action, suit, proceedings, hearing, investigation, claim, or demand).

                  (h) Tax Matters. Except as set forth on Section 4(h) of the
Disclosure Schedule,

                        (i) Sigma6 has filed all Tax Returns that it was
            required to file. All such Tax Returns were correct and complete in
            all respects. All Taxes owed by Sigma6 (whether or not shown on any
            Tax Return) based on operations through the Stub Period End have
            been paid or accrued on the Stub Period End Balance Sheet. Sigma6
            currently is not the beneficiary of any extension of time within
            which to file any Tax Return. No claim has ever been made by any
            taxing authority in a jurisdiction where Sigma6 does not file Tax
            Returns that it is or may be subject to taxation by that
            jurisdiction. There are no Security Interests on any of the assets
            of Sigma6 that arose in connection with any failure (or alleged
            failure) to pay any Tax, other than for Taxes that are not yet due
            which have been accrued for since the Most Recent Fiscal Year End.

                        (ii) Sigma6 has withheld and paid all Taxes required to
            have been withheld and paid in connection with amounts paid or owing
            to any employee, creditor, independent contractor, or other third
            party and Sigma6 has properly reflected the status of all employees
            and independent contractors in connection


                                      -22-
<PAGE>

            therewith as required by applicable Tax law and the Fair Labor
            Standards Act of 1938, as amended, and the rules and regulations
            promulgated thereunder.

                        (iii) Neither Sellers nor any of the officers of Sigma6
            have received, nor do any of them have any Basis to expect to
            receive, any notice that any taxing authority intends to assess any
            additional Taxes for any period for which Tax Returns have been
            filed. There is no dispute or claim concerning any Tax Liability of
            Sigma6 either (A) claimed or raised by any authority in writing or
            (B) as to which the Sellers or the officers of Sigma6 or employees
            responsible for Tax matters of Sigma6 have Knowledge based upon
            personal contact with any agent of such authority. Section 4(h) of
            the Disclosure Schedule lists all federal, state, local, and foreign
            income Tax Returns filed with respect to Sigma6 for taxable periods
            ended on or after December 31, 1990, indicates those Tax Returns
            that have been audited, and indicates those Tax Returns that
            currently are the subject of audit. Sigma6 has delivered to the
            Buyer correct and complete copies of all federal income Tax Returns
            filed, examination reports received, and statements of deficiencies
            assessed against or agreed to, by Sigma6 since December 31, 1990.

                        (iv) Sigma6 has not waived any statute of limitations in
            respect of Taxes or agreed to any extension of time with respect to
            a Tax assessment or deficiency.

                        (v) Sigma6 has not filed a consent under Code Sec.
            341(f) concerning collapsible corporations. Sigma6 has not made any
            payments, is not obligated to make any payments, nor is a party to
            any agreement that under certain circumstances could obligate it to
            make any payments that will not be deductible to Sigma6 under Code
            Sec. 280G. Sigma6 has not been a United States real property holding
            corporation within the meaning of Code Sec. 897(c)(2) during the
            applicable period specified in Code Sec. 897(c)(1)(A)(ii). Sigma6
            has disclosed on its federal income Tax Returns all positions taken
            therein that could give rise to a substantial understatement of
            federal income Tax within the meaning of Code Sec. 6662. Sigma6 is
            not a party to any Tax allocation or sharing agreement. Sigma6 has
            never been (nor has any Liability for unpaid Taxes because it once
            was) a member of an Affiliated Group filing a consolidated federal
            income Tax Return and has never incurred any Liability for the Taxes
            of any Person under Treas. Reg.ss.1.1502-6 (or any similar provision
            of state, local, or foreign law), as a transferee or successor, by
            contract, or otherwise, during any part of any consolidated return
            year within any part of which consolidated return year also was a
            member of the Affiliated Group.

                        (vi) Section 4(h) of the Disclosure Schedule sets forth
            the following information with respect to Sigma6 as of the most
            recent practicable date (as well as on an estimated pro forma basis
            as of the Closing giving effect to the consummation of the
            transactions contemplated hereby): (A) the amount of any net
            operating loss, net capital loss, unused investment or other credit,
            unused foreign


                                      -23-
<PAGE>

            tax, or excess charitable contribution allocable to Sigma6; and (B)
            the amount of any deferred gain or loss allocable to Sigma6 arising
            out of any Deferred Intercompany Transaction.

                        (vii) The unpaid Taxes of Sigma6 through the Stub Period
            End do not exceed the reserve for Tax Liability set forth on the
            face of the Stub Period Balance Sheet.

                  (i) Tangible Assets. Sigma6 owns or leases substantially all
tangible assets necessary for the conduct of Sigma6's Business as presently
conducted and as presently proposed to be conducted. Each such tangible asset is
free from Material defects (patent or latent), has been maintained in accordance
with normal industry practice, is in good operating condition and repair
(subject to normal wear and tear), and is suitable for the purposes for which it
presently is used.

                  (j) Owned Real Property. Sigma6 does not own nor does it have
any interest in any real property or improvements thereon (other than the leases
disclosed in Section 4(l) of the Disclosure Schedule, and the leasehold
improvements relating to the same) nor does Sigma6 have any options, agreements
or contracts under which it has the right or obligation to acquire any interest
in any real property or improvements (other than as disclosed in Section 4(l) of
the Disclosure Schedule)

                  (k) Intellectual Property.

                        (i) Attached hereto as Section 4(k) of the Disclosure
            Schedule is a list and brief description of all Intellectual
            Property owned or utilized by Sigma6. Sigma6 has furnished Buyer
            with copies of all license agreements to which Sigma6 is a party,

            Schedule or as specfically excluded under this Section 4(k), Sigma6

            business as presently conducted or currently proposed to be
            conducted without the payment of any royalty or similar payment.
            Furthermore, Sigma6 is not infringing on any Intellectual Property
            right of others; provided, however, that the foregoing
            representation related to infringement (A) shall not apply to
            generally commercially available Intellectual Property which is
            licensed by Sigma6 for its own use and (B) shall only apply to
            infringement which individually or in the aggregate results in a
            Material Adverse Effect to Sigma6. In addition, none of Sellers nor
            Sigma6 has Knowledge of any infringement by others of any such
            rights owned by Sigma6, except as set forth in Section 4(k) of the
            Disclosure Schedule.

                        (ii) All licenses set forth on Section 4(k) of the
            Disclosure Schedule are valid and binding obligations of Sigma6, and
            to the Knowledge of the Sellers and Sigma6, of the other parties

            parties thereto in accordance with their respective terms, except

            valid license without infringement by Sigma6, all Intellectual
            Property utilized in the operation of the business of Sigma6.

            consultants, and contractors, who have contributed to or
            participated in the conception and development of any Intellectual
            Property owned by Sigma6 (the "Sigma6 IP") have executed the
            nondisclosure agreements listed on Section 4(k) of the Disclosure
            Schedule and either (1) have been party to a written agreement with
            Sigma6 that on its face has accorded Sigma6 full, effective,
            exclusive and original ownership of all Sigma6 IP, or (2) have
            executed appropriate instruments of assignment in favor of Sigma6 as
            assignee that have conveyed to Sigma6 full, effective, and exclusive
            ownership of all Sigma6 IP.

            information contained therein was correct and complete in all
            respects) under all applicable laws (including rules and regulations
            thereunder).

                        (vi) Sigma6 has possession of all records and documents
            it was required to retain under all applicable laws (including rules

                  (e) Access.

                        (i) Only in the event that neither Buyer or Sellers
            exercised its right to terminate this Agreement as provided in
            Section 9 herein, each Party will permit (and the Sellers will cause
            Sigma6 to permit) representatives of the other Party to have access
            at reasonable times, and in a manner so as not to interfere with the
            normal business operations of such Party, to the headquarters of
            such Party and to all books, records, contracts, Tax records, and
            documents of or pertaining to such Party; provided, however, that
            Buyer shall direct all requests for information and material only
            through Sellers' Representative, unless otherwise agreed to by Buyer
            and Seller's Representative in writing.

of the Parties to consummate the transactions contemplated by this Agreement.
Except for the right of Sigma6 to update any Disclosure Schedule as provided in
Section 4 hereof, no disclosure by any Sellers or Sigma6 pursuant to this
Section 5(f) shall be deemed to amend or supplement Annex II or the Disclosure
Schedule or to prevent or cure any misrepresentation, breach of warranty, and/or
breach of covenant.

                  (g) Exclusivity. Until termination or consummation as provided
for herein, Sigma6 and the Sellers will not (i) solicit, initiate, or encourage

or recapitalization, (B) merger or consolidation, (C) acquisition or purchase of
securities or assets, or (D) similar transaction or business combination
involving Sigma6 or (ii) participate in any discussions or negotiations
regarding, furnish any information with respect to, assist or participate in, or
facilitate in any other manner any effort or attempt by any person to do or seek
any of the foregoing. The Sellers will notify the Buyer immediately if any
person makes any proposal, offer, inquiry, or contact with respect to any of the
foregoing.

                  (h) Cancellation and Exchange of Options, Bonus Programs and
Phantom Stock Plans. Sigma6 shall have provided for the cancellation, at or
prior to the Closing, of all Sigma6 Options, stock option plans, deferred bonus
programs or phantom equity plans. The amounts payable for the cancellation of
the Sigma6 Options will be paid by Sellers and at no cost to Sigma6 or Buyer,
or, if paid by Sigma6, such payments will be a reduction of the Cash Portion of
the Purchase Price pursuant to Section 2(h). In conjunction with the
cancellation of such programs, all eligible employees who have not executed new
employment agreements shall have signed cancellation agreements which include
provisions that each employee will not, for a period of one year from the date
of Closing or one year from the termination of his or her employment with his or
her employer (i.e., Sigma6) whichever period is longer: (i) service or solicit
any customers of his or her employer, or (ii) solicit for employment any
employee of his or her employer.

            6. Additional Agreements and Covenants. The Parties further covenant
and agree as follows:

                  (a) Sale of Delphi Automotive Systems Receivable to Sellers at
Closing. The parties hereto agree that Sellers shall have the right to purchase
from Sigma6 the accounts receivable due from Delphi Automotive Systems (the
"Delphi Receiveable") in the aggregate amount of $250,000.00 simultaneous with
the Closing. In the event of such purchase, the parties hereto further agree
that (i) Sigma6 will utilize the funds received from the Sellers from the sale
of the Delphi Receivable to pay down any Funded Indebtedness then existing on
the Closing Date which has not been paid; (ii) the Sellers shall be the sole
owner of the Delphi Receivable and (iii) upon receipt by Sigma6 of any sums in
payment of the Delphi Receivable, such payments shall be held in trust and
delivered to Sellers' Representative properly endorsed.

                  (b) General. In case at any time after the Closing any further
action is necessary or desirable to carry out the purposes of this Agreement,
each of the Parties will take such further action (including the execution and
delivery of such further instruments and documents) as any other Party
reasonably may request, all at the sole cost and expense of the requesting Party
(unless the requesting Party is entitled to indemnification for such cost and
expense under Section 8 below). The Sellers and Sigma6 acknowledge and agree
that from and after the Closing the Buyer will be entitled to possession of all
documents, books, records, agreements, and financial data of any sort relating
to Sigma6; provided that Sellers may retain any copies of the foregoing as shall
be necessary to comply with applicable tax and other laws, regulations and
ordinances.

                  (c) Litigation Support. In the event and for so long as any
Party actively is contesting or defending against any charge, complaint, action,
suit, proceeding, hearing,


                                      -35-
<PAGE>

investigation, claim, or demand in connection with (i) any transaction
contemplated under this Agreement or (ii) any fact, situation, circumstance,
status, condition, activity, practice, plan, occurrence, event, incident,
action, failure to act, or transaction on or prior to the Closing Date involving
Sigma6, each of the other Parties will cooperate with him or it and his, her or
its counsel in the contest or defense, make available their personnel, and
provide such testimony and access to their books and records as shall be
necessary in connection with the contest or defense, all at the sole cost and
expense of the contesting or defending Party (unless the contesting or defending
Party is entitled to indemnification therefor under Section 8 below).

                  (d) Transition. The Sellers will not take any action that
primarily is designed or intended to have the effect of discouraging any lessor,
licenser, customer, supplier, or other business associate of Sigma6 from
maintaining the same business relationships with Sigma6 after the Closing for a
period of twenty-four (24) months thereafter as it maintained with Sigma6 prior
to the Closing. The Sellers will refer all customer inquiries relating to
Sigma6's Business to the Buyer and/or Sigma6 from and after the Closing for a
period of twenty-four (24) months thereafter.

                  (e) Confidentiality. The Sellers will treat and hold as such
all of the Confidential Information, refrain from using any of the Confidential
Information except in connection with this Agreement for a period of three (3)
years from the Closing Date, and except as otherwise permitted hereunder or as
may be required by law, deliver promptly to the Buyer or destroy, at the
reasonable request and option of the Buyer, all tangible embodiments (and all
copies) of the Confidential Information which are in its possession. In the
event that the Sellers are requested or required (by request for information or
documents in any legal proceeding, interrogatory, subpoena, civil investigative
demand, or similar legal process) to disclose any Confidential Information, the
Sellers will notify the Buyer promptly of the request or requirement so that the
Buyer may seek an appropriate protective order or waive compliance with the
provisions of this Section 6(e). If, in the absence of a protective order or the
receipt of a waiver hereunder, the Sellers are compelled to disclose any
Confidential Information or else stand liable for contempt, then Sellers may
disclose the Confidential Information; provided, however, that the Sellers shall
use their reasonable efforts to cooperate with Buyer to obtain, at the
reasonable request of the Buyer, an order or other assurance that confidential
treatment will be accorded to such portion of the Confidential Information
required to be disclosed as the Buyer shall reasonably designate.

                  (f) Termination of Bank Facilities; Release of Guaranties.
Sellers shall take all reasonable best efforts necessary to (i) retire all of
Sigma6's outstanding bank indebtedness and (ii) fully, completely and
unconditionally release and/or substitute Buyer or Sigma6 at or prior to Closing
as guarantor for the Sellers on all leases of Sigma6 or other guarantees.

                  (g) Monitoring Information. Prior to the Closing, each Party
shall deliver such information to the other Party as may reasonably be requested
by Buyer, Sigma6 or Sellers.


                                      -36-
<PAGE>

                  (h) Landlords' Consents. On or before the Closing Date,
Sellers shall cause Sigma6 to obtain from its landlords (to the extent required
under the pertinent premises lease) written consent to the assignment of all
leases being assumed by Buyer, which assignments are deemed to have resulted
from the transactions contemplated by this Agreement.

                  (i) Additional Tax Matters. Buyer and Sellers recognize that
each of them will need access, from time to time, after the Closing Date, to
certain accounting and Tax records and information held by the Buyer and/or
Sigma6 to the extent such records and information pertain to events occurring on
or prior to the Closing Date; therefore, Buyer agrees to cause Sigma6 to (A) use
its best efforts to properly retain and maintain such records for a period of
six (6) years from the date the Tax Returns for the year in which the Closing
occurs are filed or until the expiration of the statute of limitations as may be
extended by law from time to time that applies to the Tax Return in question
(i.e., including Tax Returns for years preceding the year in which the Closing
occurs), whichever is later, and (B) allow the Sellers and their agents and
representatives at times and dates mutually acceptable to the Parties, to
inspect, review and make copies of such records as such other party may deem
necessary or appropriate from time to time, such activities to be conducted
during normal business hours and at the other Party's expense.

                  (j) Covenant Not to Compete. For a period of four (4) years
from and after the Closing Date, the Sellers will not, directly or indirectly,
as principal, agent, trustee or through the agency of any corporation,
partnership, association or agent or agency, (i) own, manage, control,
participate in, consult with, render services for, or in any manner engage in
any activity or business competing with the Business in the United States of
America and Canada, (ii) service or solicit any of Sigma6's Business from any
customer of Sigma6, (iii) request or advise any customer of Sigma6 to withdraw,
curtail or cancel such customer's business with Sigma6, or (iv) solicit for
employment any person employed by Sigma6 at any time within the 180 day period
immediately preceding such solicitation; provided, however, that no owner of
less than five percent (5%) of the outstanding stock of any publicly traded
corporation shall be deemed to engage solely by reason thereof in any of its
businesses and provided, further, that the Harmony House Online relationship as
specifically described in Section 6(m) shall not be a violation of this covenant
not to compete (provided that the Sellers comply with the provisions of Section
6(m)). For purposes of this Agreement, the Parties have agreed to allocate
$50,000 of the aggregate Purchase Price to the covenant not to compete contained
in this Section 6(j).

                  (k) Reorganization Intent. The Parties agree that the Merger
is intended to be a tax-free reorganization under Section 368 of the Code, and
this Agreement is intended to be a "plan of reorganization" within the meaning
of the regulations promulgated under such section of the Code. None of the
Parties has taken, shall take or fail to take any action that would jeopardize
the qualification of the Merger as such a tax-free reorganization (other than
actions contemplated by this Agreement or as may be otherwise legally required).

                  (l) Conduct During Earned Payout Period. Sellers acknowledge
and agree that, during the Earned Payout Period, Buyer shall be entitled to
oversee the operation and management of Sigma6's Business, including the setting
of goals and review of budgets and performance. The Sellers further agree,
during the Earned Payout Period, not to allow Sigma6 to


                                      -37-
<PAGE>

cut staff, capital expenditures and general and administrative expenses or take
other actions that are not consistent with Sigma6's prior practices and/or
prudent business practices, and Sellers agree not and not to allow Sigma6 to
engage in any activity in order to increase current year profits of the business
of Sigma6 at the expense of the longer term growth of the business of Sigma6.
During the Earned Payout Period, the Buyer agrees that it will not (i)
unreasonably require that the business of Sigma6 be operated substantially
different as it was prior to the Merger except in so far as the prior practices
of Sigma6 were imprudent or unreasonable or its productivity efficiency and
profitability can be improved and increased through economies of scale, Buyer's
experience or otherwise; (ii) unreasonably change (A) the prices charged for
Sigma6's services, (B) the level of compensation of Sigma6's full-time corporate
employees or (C) the level Sigma6's general and administrative expenses, unless
the prior business practices were unreasonable or imprudent and/or unless the
changes are reasonably necessary to support the growth of Sigma6's Business.

                  (m) Harmony House Relationship. The Sellers shall have the
option to participate with Harmony House Inc. ("Harmony House") in a limited
partnership, called Harmony House Online, L.P. ("Harmony House Online");
provided, however, that all E-Commerce Services provided to Harmony House Online
or any Affiliate thereof shall be provided by the Buyer or its Affiliates
pursuant to an arms-length agreement; and provided, further that, except in his
capacity as an employee of Buyer or its Affiliate, the sole relationship between
any Seller and Harmony House shall be his ownership interest therein pursuant to
the terms of this Agreement (e.g. there shall be no consulting or other services
provided by any Seller to Harmony House). "E-Commerce Services" shall mean all
web site design and development, software development, e-commerce transaction
processing and all site hosting. In the event that (i) an exclusive services
contract between Harmony House Online and the Buyer for the provision of
E-Commerce Services to Harmony House Online (A) is not executed within a
reasonable time after the formation of Harmony House Online, or (B) is
terminated or (ii) any E-Commerce Services are provided to Harmony House Online
by a party other than the Buyer or its Affiliates, then the Sellers'
participation in any manner with Harmony House Online shall be discontinued (and
all Sellers shall immediately withdraw their interests or shall cause their
Affiliates to withdraw their interests in Harmony House Online) unless Buyer
agrees to allow continued participation of Sellers by its express written
consent.

                  (n) Employee Benefits.

                        (i) Immediately following the Closing Date, the
            employees of Sigma6, during such time as their employment with
            Buyer, Newco and/or their affiliates is continued, shall be eligible
            to participate in Buyer's Employee Benefit Plans on the same terms
            and conditions as similarly situated employees of the Buyer are
            eligible to participate therein. Buyer shall cause Buyer's Benefit
            Plans to recognize prior service of a Sigma6 employee with Sigma6 to
            the extent recognized under the corresponding Seller Benefit Plans
            prior to the Closing as service with Buyer and its affiliates for
            purposes of (i) any Buyer Employee Benefit Plan that is not an
            Employee Pension Benefit Plan for purposes of any waiting period and
            eligibility requirements and (ii) any Buyer Benefit Plan that is an
            Employee Pension


                                      -38-

            early retirement benefits) and vesting (but not benefit accrual)
            thereunder.

                        (ii) Newco or Buyer shall, from and after the Closing
            Date, provide continuation coverage under Part 6 of Subtitle B of
            Title I of ERISA and Code Section 4980B for those covered employees
            of Sigma6 with respect to whom, on or prior to the Closing Date, a
            "qualifying event" (as defined in ERISA Section 603 and Code Section
            4980B(f)(3)) has occurred, and shall meet all continuing obligations
            thereunder.

            7. Conditions to Obligations to Close.

                  (a) Conditions to Obligation of the Buyer. The obligation of

            notices to, filings with, and authorizations, consents and approvals
            of governments, governmental agencies, and third parties as set
            forth herein or in the Disclosure Schedule including any Filing

            charge would (A) prevent consummation of any of the transactions
            contemplated by this Agreement, (B) cause any of the transactions
            contemplated by this Agreement to be rescinded following
            consummation, or (C) affect adversely the right of the Buyer to own,
            operate, or control Sigma6 Shares or Sigma6 (and no such judgment,

            effect);

                        (v) The Sellers and Sigma6 shall have delivered to the

            discretion, may add to or subtract from the list of those employees
            it determines to be or not to be Key Employees on Annex IV and thus

                        (iv) no action, suit or proceeding shall be pending or
            threatened before any court or quasi-judicial or administrative
            agency of any federal, state, local, or foreign jurisdiction wherein
            an unfavorable judgment, order, decree, stipulation, injunction, or
            charge would (A) prevent consummation of any of the transactions
            contemplated by this Agreement or (B) cause any of the transactions
            contemplated by this Agreement to be rescinded following
            consummation (and no such judgment, order, decree, stipulation,
            injunction, or charge shall be in effect);

                        (v) the Buyer shall have delivered to the Sellers a

            8. Remedies for Breaches of This Agreement.

                  (a) Survival. All of the representations and warranties of the
Sellers contained in Section 4 above (other than the representations and
warranties of the Sellers contained


                                      -43-
<PAGE>

in Section 4(h) above) shall survive the Closing hereunder (unless the Buyer
knew of any misrepresentation or breach of warranty at the time of the Closing
pursuant to a writing provided by Sigma6 or Seller) and continue in full force
and effect for a period of three (3) years thereafter. The other
representations, warranties, and covenants of the Parties contained in this
Agreement (including the representations and warranties of the Sellers contained
in Section 4(h) above) shall survive the Closing (unless the damaged Party knew
of any misrepresentation or breach of warranty or covenant pursuant to a writing
provided by the other Party at the time of the Closing) and continue in full
force and effect for the applicable statute of limitations period thereafter,
except as otherwise provided elsewhere in this Agreement.

                  (b) Indemnification Provisions for Benefit of the Buyer.

                        (i) In the event Sigma6 or the Sellers, as applicable,
            breach any of their representations, warranties, agreements, and
            covenants contained herein, (other than a breach by a Seller of
            his/her individual representations and warranties, which are
            addressed in Section (8)(b)(ii) below) and provided that the
            particular representation, warranty, agreement, or covenant survives
            the Closing and that the Buyer makes a written claim for
            indemnification against the Sellers pursuant to Section 10(h) below
            within the applicable survival period, then the Sellers agree to
            jointly and severally indemnify the Buyer from and against the
            entirety of any Adverse Consequences the Buyer may suffer through
            and after the date of the claim for indemnification (including any
            Adverse Consequences the Buyer may suffer after the end of the
            applicable survival period resulting from, arising out of, relating
            to, in the nature of, or caused by the breach; provided, however,
            that the Sellers shall not have any obligation to indemnify the
            Buyer from and against any Adverse Consequences resulting from,
            arising out of, relating to, in the nature of, or caused by the
            breach of any representation or warranty or covenant of Sellers in
            this Agreement (i) until the Buyer has suffered aggregate losses by
            reason of all such breaches in excess of a $15,000 threshold (at
            which point the Sellers will be obligated to indemnify the Buyer
            from and against all such aggregate indemnifiable losses relating
            back to the first dollar) or (ii) in excess of the Purchase Price
            (after which point Sellers shall have no obligation to indemnify
            Buyer from and against further such Adverse Consequences); provided,
            further, however, that the limitations set forth (a) in (i) and (ii)
            above specifically shall not apply to the liability of Sellers with
            respect to Adverse Consequences resulting from or attributable to
            intentional fraud or any willful misconduct by the Sellers and (b)
            in (i) above specifically shall not apply to the liability of
            Sellers with respect to any breaches of the representations and
            warranties contained in Section 4(g), Section 4(h) and Section 4(n)
            hereof. Notwithstanding the foregoing, the liability of each Seller
            shall, in all events, be limited to the portion of the Purchase
            Price actually received by such Seller (other than the breach by a
            Seller of his/her individual representations and warranties in
            Section 3(a)).

                        (ii) In the event any Seller breaches any of its
            representations and warranties, contained in Section 3(a) herein,
            and provided that the particular


                                      -44-
<PAGE>

            representation, warranty, or covenant survives the Closing and that
            the Buyer makes a written claim for indemnification against such
            Seller pursuant to Section 10(h) below within the applicable
            survival period, then, such Seller agrees to indemnify the Buyer
            from and against the entirety of any Adverse Consequences the Buyer
            may suffer through and after the date of the claim for
            indemnification (including any Adverse Consequences the Buyer may
            suffer after the end of the applicable survival period) resulting
            from, arising out of, relating to, in the nature of, or caused by
            the breach.

                        (iii) The Sellers agree to indemnify the Buyer from and
            against the entirety of any Adverse Consequences the Buyer may
            suffer resulting from, arising out of, relating to, in the nature
            of, or caused by any Liability of Sigma6 arising under
            Reg.ss.1.1502-6 (because Sigma6 once was a member of an Affiliated
            Group during any part of any consolidated return year within any
            part of which consolidated return year any corporation other than
            Sigma6 also was a member of the Affiliated Group). The Sellers agree
            to indemnify the Buyer from and against the entirety of any transfer
            Taxes which may become due and owing by reason of the transactions
            contemplated by this Agreement.

                        (iv) The Sellers shall indemnify the Buyer from and
            against the entirety of all Tax Liability created from and the
            conversion by Sigma6 to the accrual basis of tax accounting from the
            cash basis of tax accounting to the extent such Taxes are in excess
            of the reserve, if any, for such Tax Liability used to determine the
            Net Worth of Sigma6.

                        (v) The Sellers agree to indemnify the Buyer from and
            against (A) the entirety of any brokerage fees or investment banking
            commissions due by Sellers or Sigma6 by reason of the transactions
            contemplated by this Agreement and (B) any Adverse Consequences the
            Buyer may suffer resulting from, arising out of, relating to, in the
            nature of, or caused by any Liability of Sigma6 (to the extent such
            Liability is not otherwise included or reserved for on the balance
            sheet of Sigma6 used to determine the Net Worth adjustment) incurred
            in connection with (i) any obligation of Sigma6 to Agis Global
            Internet Services ("Agis") in connection with any dispute between
            Sigma6 and Agis which has not been completely resolved prior to the
            Closing Date, (ii) any obligation of Sigma6 to Ameritech in
            connection with disputed fees in existence as of the Closing Date,
            (iii) the nonpayment of any license fees described on Section 4(g)
            of the Disclosure Schedule, (iv) any portion of the receivable by
            Cherub (as referenced in the Disclosure Schedule) which is not
            collected by Sigma6, or (v) any payments made by Cortex or Buyer to
            the Seller named Jani Anderson in connection with the guarantee of
            such Seller's automobile lease.

                        (vi) The Sellers agree to indemnify Buyer from and
            against the entirety of any Adverse Consequences the Buyer or its
            affiliates may suffer resulting from, arising out of, relating to,
            in the nature of, or caused by any Liability


                                      -45-
<PAGE>

            related to Harmony House Online, except those Liabilities for which
            Buyer would be liable in the Ordinary Course of Business and are
            specifically assumed by Buyer (or its affiliates) under contracts to
            provide E-Commerce Services to Harmony House Online.

                        (vii) The Parties shall make appropriate adjustments for
            tax benefits in determining the liability of the Sellers under this
            Section 8.

                  (c) Matters Involving Third Parties. If any third party shall
notify any Party (the "Indemnified Party") with respect to any matter which may
give rise to a claim for indemnification against any other Party (the
"Indemnifying Party") under this Section 8, then the Indemnified Party shall
notify in writing each Indemnifying Party thereof promptly, which notice shall
describe the matter in reasonable detail, including relevant evidence and
estimated loss; provided, however, that no delay on the part of the Indemnified
Party in notifying any Indemnifying Party shall relieve the Indemnifying Party
from any liability or obligation hereunder unless (and then solely to the
extent) the Indemnifying Party thereby is damaged and materially prejudiced from
adequately defending such claim. In the event any Indemnifying Party notifies
the Indemnified Party within thirty (30) days after the Indemnified Party has
given notice of the matter that the Indemnifying party is assuming the defense
thereof, (A) the Indemnifying Party will defend the Indemnified Party against
the matter with counsel of its choice reasonably satisfactory to the Indemnified
Party, (B) the Indemnified Party may retain separate co-counsel at its sole cost
and expense (except that the Indemnifying Party will be responsible for the fees
and expenses of the separate co-counsel to the extent the Indemnified Party
reasonably concludes that the counsel the Indemnifying Party has selected has a
conflict of interest), (C) the Indemnified Party will not consent to the entry
of any judgment or enter into any settlement or compromise with respect to the
matter without the written consent of the Indemnifying Party (not to be withheld
unreasonably), and (D) the Indemnifying Party will not consent to the entry of
any judgment with respect to the matter, or enter into any settlement or
compromise which does not include a provision whereby the plaintiff or claimant
in the matter releases the Indemnified Party from all Liability with respect
thereto, without the written consent of the Indemnified Party (not to be
withheld unreasonably). In the event no Indemnifying Party notifies in writing
the Indemnified Party within thirty (30) days after the Indemnified Party has
given notice of the matter that the Indemnifying Party is assuming the defense
thereof, however, the Indemnified Party may defend against, or enter into any
settlement with respect to, the matter in any manner it reasonably may deem
appropriate. At any time after commencement of any such action, any Indemnifying
Party may request an Indemnified Party to accept a bona fide offer from the
other Party(ies) to the action for a monetary settlement payable solely by such
Indemnifying Party (which does not burden or restrict the Indemnified Party nor
otherwise prejudice him or her) whereupon such action shall be taken unless the
Indemnified Party determines that the dispute should be continued, the
Indemnifying Party shall be liable for indemnity hereunder only to the extent of
the lesser of (i) the amount of the settlement offer or (ii) the amount for
which the Indemnified Party may be liable with respect to such action. In
addition, the Party controlling the defense of any third party claim shall
deliver, or cause to be delivered, to the other Party copies of all
correspondence, pleadings, motions, briefs, appeals or other written statements
relating to or submitted in connection with the defense of the third party
claim, and

                                      -46-
<PAGE>

timely notices of, and the right to participate in (as an observer) any hearing
or other court proceeding relating to the third party claim.

                  (d) Exclusive Remedy. The Parties acknowledge and agree that
the foregoing indemnification provisions in this Section 8 shall be the
exclusive monetary remedy of the Parties for any breach of the representations,
warranties and covenants of the Parties contained in this Agreement.

                  (e) Payment; General Right of Offset. The Indemnifying Parties
shall promptly pay to the Indemnified Party in cash the amount of any Adverse
Consequences to which such Indemnified Party becomes entitled by reason of the
provisions of Section 2 or Section 8 of this Agreement. Notwithstanding the
foregoing, in connection with the indemnification of Buyer pursuant to Section
8(b)(i), Section 8(b)(iii), Section 8(b)(iv) or Section 8(b)(v), (i) Buyer shall
have the option (at Buyer's sole discretion) to first seek indemnification
payments through offset against the Escrow Sum after an indemnification claim
has been made therefor, for the amount of any Adverse Consequences or any other
payments to which Buyer becomes entitled by reason of the provisions of this
Agreement and (ii) any one or more of the Sellers shall have the option to
satisfy such Seller's obligation to the Buyer under Section 8(b) by surrendering
to Buyer that portion of the Stock Portion of the Purchase Price required to
fund that obligation (with such surrendered Stock valued at the lesser of (A)
such Stock's then-current fair market value or (B) the value stated in Section
2(h)). Furthermore, and in lieu of receiving a cash payment from the Sellers,
Buyer, in its sole discretion, may after the first anniversary of the Closing
Date elect to offset against any Earned Payout Amount payable to Sellers, after
an indemnification claim has been made therefor, the amount of any Adverse
Consequences or any other payments to which Buyer may become entitled to by
reason of the provisions of this Agreement. In the event that Buyer offsets more
than the amount of any Adverse Consequences (as finally determined), Buyer shall
be responsible to Sellers for such sums which should not have been subject to an
offset, together with interest at the prime rate of Bank Boston, N.A.

                  (f) Other Indemnification Provisions. Subject in all events to
the time limitations set forth in Section 8(a) and the monetary and other
limitations in Section 8(b) and 8(c), the foregoing indemnification provisions
are in addition to, and not in derogation of, any statutory or common law remedy
any Party may have for breach of representation, warranty, or covenant.

                  (g) Arbitration with Respect to Certain Indemnification
Matters. THE PARTIES AGREE TO SUBMIT TO ARBITRATION, IN ACCORDANCE WITH THESE
PROVISIONS, ANY DISPUTED CLAIM OR CONTROVERSY ARISING FROM OR RELATED TO THE
ALLEGED BREACH OF THIS AGREEMENT OR ANY DISPUTED INDEMNIFICATION CLAIM MADE
PURSUANT TO THIS SECTION 8. THE PARTIES FURTHER AGREE THAT THE ARBITRATION
PROCESS AGREED UPON HEREIN SHALL BE THE EXCLUSIVE MEANS FOR RESOLVING ALL
DISPUTES MADE SUBJECT TO ARBITRATION HEREIN, BUT THAT NO ARBITRATOR SHALL HAVE
AUTHORITY TO EXPAND THE SCOPE OF THESE ARBITRATION PROVISIONS. ANY ARBITRATION
HEREUNDER SHALL BE CONDUCTED UNDER THE COMMERCIAL ARBITRATION RULES OF THE
AMERICAN ARBITRATION ASSOCIATION (AAA). EITHER PARTY MAY INVOKE ARBITRATION
PROCEDURES


                                      -47-
<PAGE>

HEREIN BY WRITTEN NOTICE FOR ARBITRATION CONTAINING A STATEMENT OF THE MATTER TO
BE ARBITRATED. THE PARTIES SHALL THEN HAVE FOURTEEN (14) DAYS IN WHICH THEY MAY
IDENTIFY A MUTUALLY AGREEABLE, NEUTRAL ARBITRATOR. AFTER THE FOURTEEN (14) DAY
PERIOD HAS EXPIRED, THE PARTIES SHALL PREPARE AND SUBMIT TO THE AAA A JOINT
SUBMISSION, WITH EACH PARTY TO CONTRIBUTE HALF OF THE APPROPRIATE ADMINISTRATIVE
FEE. IN THE EVENT THE PARTIES CANNOT AGREE UPON A NEUTRAL ARBITRATOR WITHIN
FOURTEEN (14) DAYS AFTER WRITTEN NOTICE FOR ARBITRATION IS RECEIVED, THEIR JOINT
SUBMISSION TO THE AAA SHALL REQUEST ARBITRATORS WHO ARE PRACTICING ATTORNEYS
WITH PROFESSIONAL EXPERIENCE IN THE FIELD OF CORPORATE LAW, AND THE PARTIES
SHALL ATTEMPT TO SELECT AN ARBITRATOR FROM THE PANEL ACCORDING TO AAA

            Closing;

                        (ii) the Buyer may terminate this Agreement by giving
            written notice to the Sellers at any time prior to the Closing in
            the event the Sellers are in breach of any representation, warranty,
            or covenant contained in this Agreement in any Material respect and
            such breach has not been cured within ten (10) days of written
            notice thereof, and the Sellers may terminate this Agreement by
            giving written notice to the Buyer at any time prior to the Closing

            the Closing shall not have occurred on or before March 5, 1999 by
            reason of the failure of any condition precedent under Section 7(a)
            hereof (unless the failure results primarily from the Buyer itself
            breaching any representation, warranty, or covenant contained in
            this Agreement); or

                        (iv) the Sellers may terminate this Agreement by giving
            written notice to the Buyer at any time prior to the Closing if the
            Closing shall not have occurred on or before March 5, 1999 by reason
            of the failure of any condition precedent under Section 7(b) hereof
            (unless the failure results primarily from the Sellers himself or
            itself breaching any representation, warranty, or covenant contained
            in this Agreement).

            Nothing contained in this Section 9(a) shall alter, affect, modify

covenants of any of the Parties contained in this Agreement.

shall issue any press release or public announcement relating to the subject
matter of this Agreement prior to, at or about the Closing without the prior
written approval of the Buyer and the Sellers, which written approval will not

upon and inure to the benefit of the Parties named herein and their respective
successors and permitted assigns. No Party may assign either this Agreement or

                  (i) Governing Law. ALL QUESTIONS CONCERNING THE CONSTRUCTION,
VALIDITY AND INTERPRETATION OF THIS AGREEMENT WILL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF MICHIGAN WITHOUT GIVING EFFECT TO
ANY CHOICE OF LAW OR CONFLICT OF LAW PROVISION OR RULE (WHETHER OF THE STATE OF
MICHIGAN OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE LAWS
OF ANY JURISDICTION OTHER THAN THE STATE OF MICHIGAN.

                  (j) Amendments and Waivers. No amendment of any provision of
this Agreement shall be valid unless the same shall be in writing and signed by
the Buyer and the Sellers. No waiver by any Party of any default,
misrepresentation, or breach of warranty or covenant hereunder, whether
intentional or not, shall be deemed to extend to any prior or subsequent
default, misrepresentation, or breach of warranty or covenant hereunder or
affect in any way any rights arising by virtue of any prior or subsequent such
occurrence.

                  (k) Severability. Any term or provision of this Agreement that
is invalid or unenforceable in any situation in any jurisdiction shall not
affect the validity or enforceability of the remaining terms and provisions
hereof or the validity or enforceability of the offending term or provision in
any other situation or in any other jurisdiction. If the final judgment


                                      -51-
<PAGE>

of a court of competent jurisdiction declares that any term or provision hereof
is invalid or unenforceable, the Parties agree that the court making the
determination of invalidity or unenforceability shall have the power to reduce
the scope, duration, or area of the term or provision, to delete specific words
or phrases, or to replace any invalid or unenforceable term or provision with a
term or provision that is valid and enforceable and that comes closest to
expressing the intention of the invalid or unenforceable term or provision, and
this Agreement shall be enforceable as so modified after the expiration of the
time within which the judgment may be appealed.

                  (l) Expenses. Each of the Parties and Sigma6 will bear his,
her or its own costs and expenses (including legal fees and expenses and
investment banking fees) incurred in connection with this Agreement and the
transactions contemplated hereby. Buyer and Sellers agree that Sigma6's expenses
shall be included as Funded Indebtedness. The Sellers acknowledge and agree that
Sigma6 has not borne or will bear any of the Sellers' costs and expenses
(including any of its legal fees and expenses and investment banking fees) in
connection with this Agreement or any of the transactions contemplated hereby.

                  (m) Construction. The language used in this Agreement will be
deemed to be the language chosen by the Parties to express their mutual intent,
and no rule of strict construction shall be applied against any Party. Any
reference to any federal, state, local, or foreign statute or law shall be
deemed also to refer to all rules and regulations promulgated thereunder, unless
the context requires otherwise. The Parties intend that each representation,
warranty, and covenant contained herein shall have independent significance. If
any Party has breached any representation, warranty, or covenant relating to the
same subject matter as any other representation, warranty or covenant
(regardless of the relative levels of specificity) which the Party has not
breached, it shall not detract from or mitigate the fact that the Party is in
breach of the first representation, warranty, or covenant.

                  (n) Incorporation of Exhibits, Annexes, and Schedules. The
Exhibits, Annexes, and Schedules identified in this Agreement are incorporated
herein by reference and made a part hereof.

                  (o) Specific Performance. Each of the Parties acknowledges and
agrees that the other Parties would be damaged irreparably in the event any of
the provisions of this Agreement are not performed in accordance with their
specific terms or otherwise are breached. Accordingly, each of the Parties
agrees that the other Parties shall be entitled to an injunction or injunctions
to prevent breaches of the provisions of this Agreement and to enforce
specifically this Agreement and the terms and provisions hereof in any action
instituted in any court of the United States or any state thereof having
jurisdiction over the Parties and the matter, in addition to any other remedy to
which they may be entitled, at law or in equity.

                      FORM OF RECAPITALIZATION AGREEMENT

                  THIS RECAPITALIZATION AGREEMENT (this "AGREEMENT") is made as
of _____ __, 1999 among AppNet Systems, Inc., a Delaware corporation (the
"COMPANY"), GTCR Fund VI, L.P., a Delaware limited partnership ("GTCR FUND VI"),
GTCR VI Executive Fund, L.P., a Delaware limited partnership ("EXECUTIVE FUND"),
GTCR Associates VI, a Delaware general partnership ("ASSOCIATES FUND" and,
together with GTCR Fund VI and the Executive Fund, the "GTCR INVESTORS"), FSC
Corp. ("FSC"), Smart Technology, L.L.C. ("SMART TECHNOLOGY" and, together with
the GTCR Investors and FSC, the "STOCKHOLDERS"). Except as otherwise indicated
herein, capitalized terms used herein are defined in Section 5 hereof.

                  Each Stockholder owns the number of shares of the Company's
Class A Preferred Stock, par value $.01 per share (the "CLASS A PREFERRED") set
forth opposite such Stockholder's name on the SCHEDULE OF STOCKHOLDERS attached
hereto.

                  Section 1B of Part B.II. of Article Four of the Company's
Fourth Restated Certificate of Incorporation (the "CERTIFICATE") provides that
the Company shall, at the request of the holders of a majority of the Class A
Preferred, apply the net cash proceeds from any public offering of equity
securities to redeem the outstanding shares of Class A Preferred at a price
equal to the liquidation value thereof plus accrued and unpaid dividends
thereon. Section 6(l) of the Merger Agreement, dated as of July 31, 1998 (the
"MERGER AGREEMENT") by and among the Company, SSC Acquisition Sub #1, Inc.,
Software Services Corporation ("SSC") and the shareholders of SSC, provides that
in the event of an initial public offering of equity securities by the Company
the Company shall take all actions necessary so that the Company's Class B
Preferred Stock, par value $.01 per share (the "CLASS B PREFERRED") is either
(i) converted into shares of the Company's common stock or (ii) entitled to
receive the same per share consideration as that paid with respect to the Class
A Preferred.

                  The Company has filed a Registration Statement on Form S-1
(File No. 333-75205) (the "REGISTRATION STATEMENT") with the Securities and
Exchange Commission relating to an initial public offering (the "INITIAL PUBLIC
OFFERING") of the Company's common stock, par value $.0005 per share (the
"COMMON STOCK"), under the Securities Act. The Stockholders desire that the
Company redeem the shares of Class A Preferred with the net proceeds of the
Initial Public Offering after payment of underwriting discounts and reasonable
out-of-pocket fees and expenses incurred in connection therewith (the "NET
PROCEEDS"). However, the Company desires to use a portion of the Net Proceeds to
repay certain outstanding indebtedness, as described in the Registration
Statement (the "INDEBTEDNESS") and to maintain certain proceeds for working
capital as required by the Company's lenders. If the Company applies the
proceeds as set forth above, the remaining Net Proceeds may not be sufficient to
redeem all outstanding shares of Class A Preferred and Class B Preferred.


                                      - 1 -

                  The Stockholders and the Company desire to enter into an
agreement pursuant to which (i) the Net Proceeds remaining after the repayment
of the Indebtedness and after the application of proceeds as required by the
Company's lenders shall be used by the Company to redeem shares of Class A
Preferred and Class B Preferred and (ii) to the extent that the remaining Net
Proceeds of the Initial Public Offering are not sufficient to redeem all shares
of Class A Preferred and Class B Preferred, the remaining shares of Class A
Preferred and Class B Preferred shall be exchanged for shares of Common Stock.

                  The parties hereto agree as follows:

                  Section 1.  REDEMPTION AND EXCHANGE.

                  1A. PAYMENT OF INDEBTEDNESS; REDEMPTION. At the Closing, the
Company shall apply the Net Proceeds to repay the Indebtedness and to maintain
certain proceeds for working capital, as required pursuant to a letter dated May
___, 1999 from BankBoston, N.A. and Antares Capital Corporation (a copy of which
is attached as EXHIBIT A hereto) (the "BANK BOSTON LETTER"). Subject to the
terms of the BankBoston Letter, the Company shall use the remaining Net Proceeds
to redeem shares of Class A Preferred and Class B Preferred, on a pro rata basis
according to the aggregate liquidation value and accrued and unpaid dividends of
the Class A Preferred and Class B Preferred, respectively. The redemption price
for each share of Class A Preferred Stock shall equal the liquidation value
thereof plus accrued and unpaid dividends thereon. The redemption of the Class A
Preferred Stock pursuant to this Section 1A is referred to herein as the
"REDEMPTION." At the Closing (as defined below), each Stockholder shall tender
to the Company the shares of Class A Preferred Stock held by such Stockholder
which are being redeemed pursuant to the Redemption. As described below in
Section 1B, any shares of Class A Preferred Stock not so tendered shall have the
right to receive Exchange Shares.

                  1B. EXCHANGE OF THE REMAINING SHARES OF CLASS A PREFERRED
STOCK. At the Closing, the Company shall issue to each Stockholder a number of
shares of Common Stock equal to (i) the aggregate liquidation value plus accrued
and unpaid dividends of the shares of Class A Preferred Stock, if any, held by
such Stockholder after giving effect to the Redemption divided by (ii) the
initial offering price of a share of Common Stock in the Initial Public
Offering, in exchange for the surrender to the Company and cancellation of the
shares of Class A Preferred Stock, if any, remaining after giving effect to the
Redemption and held by such Stockholder. The shares of Common Stock to be issued
to the Stockholders hereunder are referred to herein as the "EXCHANGE SHARES."

         Second Amendment dated as of May 24, 1999 to Revolving Credit Agreement

corporation (the "Borrower"), BANKBOSTON, N.A. and the other lending
institutions listed on SCHEDULE 1 to the Credit Agreement (as hereinafter
defined) (the "Banks"), amending certain provisions of the Revolving Credit
Agreement dated as of January 8, 1999 (as amended and in effect from time to
time, the "Credit Agreement") by and among the Borrower, the Banks, BankBoston,
N.A. as agent for the Banks (the "Agent") and Antares Capital Corporation as
co-agent for the Banks. Terms not otherwise defined herein which are defined in
the Credit Agreement shall have the same respective meanings herein as therein.

         WHEREAS, the Borrower and the Banks have agreed to modify certain terms
and conditions of the Credit Agreement as specifically set forth in this Second
Amendment;

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements contained herein and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
hereby agree as follows:

         Section 1. AMENDMENT TO SECTION 1.1 OF THE CREDIT AGREEMENT. Section
1.1 of the Credit Agreement is hereby amended as follows:

         (a) The definition of "Consolidated Quick Assets" contained in ss.1.1

entirety and restating it as follows:

                  CONSOLIDATED QUICK ASSETS. All cash and Accounts Receivables
         (including, without duplication, the unbilled portion of Accounts
         Receivable for services rendered in the ordinary course of business) of
         the Borrower and its Subsidiaries on a consolidated basis that, in
         accordance with generally accepted accounting principles, are properly
         classified as current assets, PROVIDED that Accounts Receivable shall
         be included only if good and collectible as determined by the Borrower
         in accordance with established practice consistently applied and, with
         respect to such Accounts Receivable, only if (a) payable and
         outstanding not more than ninety (90) days after the date of the
         invoices for services rendered or other transaction out of which any
         such Account Receivable arose or (b) if payable and outstanding more
         than ninety (90) such days, only 75% of the aggregate value of such
         Accounts Receivable, and, to the extent the aggregate amount of such
         Accounts Receivable is in excess of $500,000, only 50% of the aggregate
         value of those Accounts Receivable which exceed $500,000; and such
         Accounts Receivable shall be taken at their face value.

                                      -2-


         (b) The definition of "Consolidated Current Liabilities" contained
in Section 1.1 of the Credit Agreement is hereby amended by inserting
immediately after the words "PROVIDED, HOWEVER," the words "any nonrecurring
one-time liabilities relating to any acquisitions permitted hereunder which
are required to be capitalized shall not be included as a Consolidated
Current Liability and"

         Section 2. AMENDMENT TO SECTION 10 OF THE CREDIT AGREEMENT. Section
10.5 of the Credit Agreement is hereby amended by deleting the words "less than
1.75:1.00 at any time" which appear in ss.10.5 and substituting in place thereof
the words "less than (a) 1.75:1.00 at any time from the Closing Date through the
fiscal quarter ended December 31, 1998; (b) 1.70:1.00 at any time during the
fiscal quarter ended March 31, 1999; and (c) 1.75 at any time thereafter"

         Section 3. AMENDMENT TO SECTION 13 OF THE CREDIT AGREEMENT. Section
13.1 of the Credit Agreement is hereby amended by deleting Section 13.1(p) in
its entirety and restating it as follows:

                  (p) the Borrower shall at any time, legally or beneficially
         own less than 100% of the capital stock of each Subsidiary (other than
         AppNet Commerce Services, Inc.), or (i) prior to the IPO, the Investors
         shall at any time, legally or beneficially own less than fifty one
         percent (51%) of the capital stock of the Borrower, as adjusted
         pursuant to any stock split, stock dividend or recapitalization or
         reclassification of the capital of the Borrower and (ii) subsequent to
         the IPO, any person or group of persons (within the meaning of Section
         13 or 14 of the Securities Exchange Act of 1934, as amended) other than
         the Investors shall have acquired beneficial ownership (within the
         meaning of Rule 13d-3 promulgated by the Securities and Exchange
         Commission under said Act) of thirty percent (30%) or more of the
         common stock of the Borrower (as determined on a fully diluted basis),
         or during any period of twelve consecutive calendar months, individuals
         who were directors (the "Incumbent Board") of the Borrower on the first
         day of such period shall cease to constitute a majority of the board of
         directors of the Borrower, PROVIDED, HOWEVER, that if the election or
         nomination for election by the Borrower's common stockholders of any
         new director was approved by a vote of at least two-thirds of the
         Incumbent Board, such new director shall, for purposes of this Credit
         Agreement, be considered as a member of the Incumbent Board;

         Section 4. CONDITIONS TO EFFECTIVENESS. This Second Amendment shall not
become effective until the Agent receives a counterpart of this Second
Amendment, executed by the Borrower, each Subsidiary and the Banks

         Section 5. REPRESENTATIONS AND WARRANTIES. The Borrower hereby
represents that, on and as of the date hereof, each of the representations
and warranties made by it in Section 7 of the Credit Agreement remain true as
of the date hereof (except to the extent of changes resulting from
transactions contemplated or permitted by the Credit Agreement and the other
Loan Documents and changes occurring in the ordinary course of business that
singly or in the aggregate are not materially adverse, and to the extent that
such representations and warranties relate expressly to an earlier date),
PROVIDED, that all references therein to the Credit Agreement shall refer to
such Credit Agreement as amended hereby. In addition, the Borrower hereby
represents and warrants that the execution and delivery by the Borrower and
its Subsidiaries of

including, but not limited to the Security Documents, are hereby ratified and

Credit Agreement as amended hereby.

         Section 7. NO WAIVER. Nothing contained herein shall constitute a

         1.       PURPOSE.

                  The purpose of this Plan is to strengthen AppNet Systems,
Inc., a Delaware corporation (the "Company"), by providing an incentive to its
employees, officers, directors and consultants and thereby encouraging them to
devote their abilities and industry to the success of the Company's business
enterprise. It is intended that this purpose be achieved by extending to
employees (including future employees who have received a formal written offer
of employment), officers, directors, and consultants of the Company and its
Subsidiaries an added long-term incentive for high levels of performance and
unusual efforts through the grant of Incentive Stock Options, Nonqualified Stock
Options, Formula Options, Stock Appreciation Rights, Dividend Equivalent Rights,
Performance Awards, Share Awards, Phantom Stock and Restricted Stock (as each
term is herein defined).

         2.       DEFINITIONS.

                  2.1 "ADJUSTED FAIR MARKET VALUE" means, in the event of a
Change in Control, the highest price per Share paid to holders of the Shares in
any transaction (or series of related transactions) constituting or resulting in
a Change in Control other than pursuant to Section 2.10(b).

                  2.2 "AFFILIATE" means, with respect to any Person, any other
Person that, directly or indirectly through one or more intermediaries,
controls, or is controlled by, or under common control with, such Person. Any
Relative (for this purpose, "Relative" means a spouse, child, parent, parent of
spouse, sibling or grandchild) of an individual shall be deemed to be an
Affiliate of such individual for purposes hereof. Neither the Company nor any
Person controlled by the Company shall be deemed to be an Affiliate of any
holder of Company stock.

                  2.3 "AGREEMENT" means the written agreement between the
Company and an Optionee or Grantee evidencing the grant of an Option or Award

                  2.7 "BOARD" means the Board of Directors of the Company.

                  2.8 "CAUSE" means:

                           (a) for purposes of Section 6.4, the term "Cause"

conversion of assets or opportunities of the Company or any of its Subsidiaries
or (iv) willful violation of any law, rule or regulation (other than traffic
violations or similar offenses) in connection with the performance of duties as
a Director; PROVIDED, HOWEVER, that if the term "Cause" is defined in the
Articles of Incorporation of the Company, Cause shall have the meaning given
such term in such Articles, or

                           (b) in the case of an Optionee or Grantee whose
employment with the Company or a Subsidiary is, as the date of the applicable
Agreement, subject to the terms of an employment agreement between such Optionee

definition of "Cause," the term "Cause" as used in this Plan or any Agreement

                  2.9 "CHANGE IN CAPITALIZATION" means any increase or reduction

Options or Awards granted under this Plan or otherwise by the Company) of any
Voting Securities of the Company by any Person, immediately after which such
Person has Beneficial Ownership of fifty percent (50%) or more of the combined
voting power of the Company's then outstanding Voting Securities; PROVIDED,
HOWEVER, in determining whether a Change in Control has occurred pursuant to
this Section 2.10(a), Voting Securities which are acquired in a "Non-Control

majority of its voting power or its voting equity securities or equity interest

definition, a "Related Entity"), (ii) the Company or any Related Entity, or
(iii) any Person in connection with a "Non-Control Transaction" (as hereinafter
defined);

                           (b) The individuals who, as of the date hereof, are
members of the Board (the "Incumbent Board"), cease for any reason to constitute
at least a majority of the members of the Board; PROVIDED, HOWEVER, that if the
election, or nomination for election by the Company's common stockholders, of
any new director was approved by a vote of at least a majority of the Incumbent
Board, such new director shall, for purposes of this Plan, be considered as a
member of the Incumbent Board; PROVIDED FURTHER, HOWEVER, that no individual
shall be considered a member of the Incumbent Board if such individual initially
assumed office as a result of either an actual or threatened "Election Contest"
(as described in Rule 14a-11 promulgated under the Exchange Act) or other actual
or threatened solicitation of proxies or consents by or on behalf of a Person

                           (b) In connection with the granting of a Performance
Unit denominated in dollars, the number of Shares shall be reduced by an amount
equal to the quotient of (i) the dollar amount in which the Performance Unit is
denominated, divided by (ii) the Fair Market Value of a Share on the date the
Performance Unit is granted.

                  4.4 Whenever any outstanding Option or Award or portion
thereof expires, is canceled, or is otherwise terminated for any reason without
having been exercised or payment having been made in respect of the entire
Option or Award, the Shares allocable to the expired, canceled, or otherwise
terminated portion of the Option or Award may again be the subject of Options or
Awards granted hereunder.

         5. OPTION GRANTS FOR ELIGIBLE INDIVIDUALS.

                  5.1 AUTHORITY OF COMMITTEE. Subject to the provisions of the
Plan, the Committee shall have full and final authority to select those Eligible
Individuals who will receive Options, the terms and conditions of which shall be
set forth in an Agreement; PROVIDED, HOWEVER, that no Eligible Individual shall
receive any Incentive Stock Options unless he is an employee of the Company, a
Parent or a Subsidiary at the time the Incentive Stock Option is granted.

                  5.2 PURCHASE PRICE. The purchase price (which may be greater
than, less than or equal to the Fair Market Value on the date of grant) or the
manner in which the purchase price is to be determined for Shares under each
Option shall be determined by the Committee and set forth in the Agreement
pursuant to which each Option is granted; PROVIDED, HOWEVER, that the purchase
price per Share under each Incentive Stock Option shall not be less than 100% of
the Fair Market Value of a Share on the date the Option is granted (110% in the
case of an Incentive Stock Option granted to a Ten-Percent Stockholder).

                  5.3 MAXIMUM DURATION. Options granted hereunder shall be for
such term as the Committee shall determine, PROVIDED, HOWEVER, that an Option
shall not be exercisable after the expiration of ten (10) years from the date it
is granted (five (5) years in the case of an Incentive Stock Option granted to a
Ten-Percent Stockholder); PROVIDED, FURTHER, HOWEVER, that the Committee may
provide that an Option (other than an Incentive Stock Option) may, upon the
death of the Optionee, be exercised for up to one (1) year following the date of
the Optionee's death even if such period extends beyond ten (10) years from the
date the Option is granted. The Committee may, subsequent to the granting of any
Option, extend the term thereof, but in no event shall the term as so extended
exceed the maximum term provided for in the preceding sentence.

                  5.4 EXERCISABILITY. Subject to Sections 5.5 and 7.5, each
Option shall become exercisable in such installments (which need not be equal)
and at such times as



                                      -12-
<PAGE>


may be designated by the Committee and set forth in the Agreement. To the extent
not exercised, installments shall accumulate and be exercisable, in whole or in
part, at any time after becoming exercisable, but not later than the date the
Option expires. The Committee may accelerate the exercisability of any Option or
portion thereof at any time.

                  5.5 TERMINATION. Subject to Sections 7.5 and 13 and unless
otherwise provided by the Committee, in its sole discretion, in the applicable
Agreement, the following provisions shall apply to Options upon a Termination of
Employment:

                           (a) Subject to Section 5.3, unless otherwise
determined by the Committee at the time of grant (and set forth in the
applicable Agreement) or at a later date, except in the case of Disability,
retirement on or after the Optionee's Normal Retirement Date and death as
provided in Sections 5.5(c) and 5.5(d) below, upon an Optionee's Termination of
Employment with the Company, a Parent or a Subsidiary for any reason other than
a termination for Cause, any unexercised Option held by such Optionee shall
expire three (3) months after the Optionee has a Termination of Employment and
such Option may only be exercised by the Optionee or his or her Beneficiary to
the extent that the Option or a portion thereof was exercisable on the date of
Termination of Employment; PROVIDED, HOWEVER, that no Option may be exercised
after the expiration date specified for the particular Option in the Agreement.

                           (b) If the Optionee's Termination of Employment
arises as a result of a termination for Cause, then, unless the Committee
determines otherwise at the time of the Termination of Employment, any
unexercised Options held by such Optionee shall terminate and expire
concurrently with the Optionee's Termination of Employment and no rights
thereunder may be exercised.

                           (c) Subject to Section 5.3, unless otherwise
determined by the Committee at the time of grant (and set forth in the
applicable Agreement) or at a later date, if an Optionee suffers a Disability or
retires on or after the Optionee's Normal Retirement Date, any unexercised
Option held by such disabled or retired Optionee shall expire one (1) year after
the Disability Date or date of Termination of Employment by reason of
retirement, as the case may be, and such Option may only be exercised by the
Optionee or his or her guardian or legal representative to the extent that the
Option or a portion thereof was exercisable on the Disability Date or the date
of Termination of Employment by reason of retirement, as the case may be;
PROVIDED, HOWEVER, no Option may be exercised after the expiration date
specified for the particular Option in the Agreement.

                           (d) Subject to Section 5.3, unless otherwise
determined by the Committee at the time of grant (and set forth in the
applicable Agreement) or at a later date, if an Optionee dies while still
employed by the Company, the Options which the



                                      -13-
<PAGE>


Optionee was entitled to exercise on the date of the Optionee's death may be
exercised at any time after the Optionee's death by the Optionee's Beneficiary;
PROVIDED, HOWEVER, that no Option may be exercised after the earlier of: (i) one
(1) year after the Optionee's death or (ii) the expiration date specified for
the particular Option in the Agreement. If an Optionee dies after his or her
Termination of Employment, then the Options which the Optionee was entitled to
exercise on the date of the Optionee's death may be exercised by his or her
Beneficiary within the period specified in Sections 5.5(a) or 5.5(c), as the
case may be.

                           (e) Subject to Section 5.3 and notwithstanding any
other provision of this Section 5.5, upon an Optionee's Termination of
Employment at any time on, or within one (1) year after, the occurrence of a
Change in Control, each Option held by the Optionee that was exercisable as of
the date of such Termination of Employment shall remain exercisable for a period
ending not before the earlier of (A) the first anniversary of the Termination of
Employment or (B) the expiration of the stated term of the Option.

                           (f) Unless otherwise determined by the Committee at
the time of grant (and set forth in the applicable Agreement) or at a later
date, the Option (or portion thereof), to the extent not yet vested and
exercisable as of the date of the Optionee's Termination of Employment, shall
terminate immediately upon such date.

                  5.6 DEFERRED DELIVERY OF OPTION SHARES. The Committee may, in
its sole discretion, permit Optionees to elect to defer the issuance of Shares
upon the exercise of one or more Nonqualified Stock Options granted pursuant to
the Plan. The terms and conditions of such deferral shall be determined at the
time of the grant of the Option or thereafter and shall be set forth in the
Agreement evidencing the Option.

                  5.7 MODIFICATION. No modification of a Option shall adversely
alter or impair any rights or obligations under the Option without the
Optionee's consent.

                  5.8 LIMITATIONS ON INCENTIVE STOCK OPTIONS. To the extent that
the aggregate Fair Market Value (determined as of the date of the grant) of
Shares with respect to which Incentive Stock Options granted under the Plan and
"incentive stock options" (within the meaning of Section 422 of the Code)
granted under all other plans of the Company or its Subsidiaries (in either case
determined without regard to this Section 5.8) are exercisable by an Optionee
for the first time during any calendar year exceeds $100,000, such Incentive
Stock Options shall be treated as Nonqualified Stock Options. In applying the
limitation in the preceding sentence in the case of multiple Option grants,
Options which were intended to be Incentive Stock Options shall be treated as
Nonqualified Stock Options according to the order in which they were granted
such that the most recently granted Options are first treated as Nonqualified
Stock Options.

                  6.1 GRANT. Formula Options shall be granted (i) to a
Nonemployee Director who becomes a member of the Board after May __, 1999 upon
election or appointment and (ii) to all Nonemployee Directors who are members of
the Board as follows:

                           (a) INITIAL GRANT. Each Nonemployee Director who
becomes a Director after May ___, 1999 shall, upon becoming a Director, be
granted a Formula Option in respect of [    ] Shares.

                           (b) ANNUAL GRANT. Each Nonemployee Director shall be
granted a Formula Option in respect of [     ] Shares on the first business day
of January in each year that the Plan is in effect provided that the Nonemployee
Director is a Director on such date; PROVIDED, HOWEVER, that a Nonemployee
Director shall not be entitled to receive an annual grant pursuant to this
Section 6.1(b) for the calendar year in which such Nonemployee Director is first
elected or appointed to the Board.

                           (c) TERMS AND CONDITIONS. All Formula Options granted
pursuant to this Section 6 shall be evidenced by an Agreement containing such
other terms and conditions not inconsistent with the provisions of this Plan as
determined by the Board; PROVIDED, HOWEVER, that such terms shall not vary the
price, amount or timing of Formula Options provided under this Section 6,
including provisions dealing with vesting, forfeiture and termination of such
Formula Options.

                  6.2 PURCHASE PRICE. The purchase price for Shares under each
Formula Option shall be equal to 100% of the Fair Market Value of such Shares on
the date the Formula Option is granted.

                  6.3 VESTING. Subject to Sections 6.4 and 7.5, each Formula
Option shall become fully vested and exercisable with respect to [ %] of the
Shares subject thereto on each of the [   ] anniversaries of the date of
grant; PROVIDED, HOWEVER, that the Optionee continues to serve as a Director
as of such date. If an Optionee ceases to serve as a Director for any reason,
the Optionee shall have no rights with respect to any Formula Option which
has not then vested pursuant to the preceding sentence and the Optionee shall
automatically forfeit any Formula Option or portion thereof which remains
unvested.

                  6.4 DURATION. Subject to Section 7.5, each Formula Option
shall terminate on the date which is the tenth (10th) anniversary of the date of
grant; PROVIDED, HOWEVER, that if an Optionee dies while a Director and prior to
such tenth (10th) anniversary, the Formula Option may be exercised for up to one
(1) year following the



                                      -15-
<PAGE>


date of the Optionee's death even if such period extends beyond ten (10) years
from the date the Formula Option is granted, unless terminated earlier as
follows:

                           (a) If an Optionee's service as a Director terminates
for any reason other than Disability, death or Cause, the Optionee may for a
period of three (3) months after such termination exercise his or her Formula
Option to the extent, and only to the extent, that such Formula Option or
portion thereof was vested and exercisable as of the date the Optionee's service
as a Director terminated, after which time the Formula Option shall
automatically terminate in full.

                           (b) If an Optionee's service as a Director terminates
by reason of the Optionee's resignation or removal from the Board due to
Disability, the Optionee or his or her guardian or legal representative may, for
a period of one (1) year after such termination, exercise his or her Formula
Option to the extent, and only to the extent, that such Formula Option or
portion thereof was vested and exercisable, as of the date the Optionee's
service as Director terminated, after which time the Formula Option shall
automatically terminate in full.

                           (c) If an Optionee's service as a Director terminates
for Cause, the Formula Option granted to the Optionee hereunder shall
immediately terminate in full and no rights thereunder may be exercised.

                           (d) If an Optionee dies while a Director, the Formula
Option which the Optionee was entitled to exercise on the date of the Optionee's
death may be exercised at any time after the Optionee's death by the Optionee's
Beneficiary; PROVIDED, HOWEVER, that no Formula Option may be exercised after
the first anniversary of the Optionee's death. If an Optionee dies after his or
her service as a Director terminates, then the Formula Options to which the
Optionee was entitled to exercise on the date of the Optionee's death may be
exercised by his or her Beneficiary within the period specified in Sections.
6.4(a) or 6.4 (b), as the case may be.

                           (e) Notwithstanding any other provision of this
Section 6.4, in the event an Optionee's service as a Director of the Company is
terminated at any time on, or within one (1) year after, the occurrence of a
Change in Control, each Formula Option held by the Optionee that was exercisable
as of the date of termination of the Optionee's service shall remain exercisable
for a period ending not before the earlier of (A) the first anniversary of the
termination of the Optionee's employment or service or (B) the expiration of the
stated term of the Formula Option.

                           (f) The Formula Option (or portion thereof), to the
extent not yet vested and exercisable as of the date the Director's service as a
Director terminates for any reason shall terminate immediately upon such date.

         7.       TERMS AND CONDITIONS APPLICABLE TO ALL OPTIONS.

                  7.1 ADDITIONAL TERMS. The provisions of this Section 7 shall
apply to all Options.

                  7.2 NON-TRANSFERABILITY. No Option granted hereunder shall be
transferable by the Optionee to whom it is granted otherwise than by will or by
the laws of descent and distribution or, in the case of an Option other than an
Incentive Stock Option, in the Committee's sole discretion, to a spouse or
former spouse in a transfer described in Section 1041(a) of the Code (a "Code
1041 Transfer"), and, except with respect to an Option transferred pursuant to a
Code 1041 Transfer, an Option shall be exercisable during the lifetime of such
Optionee only by the Optionee or his or her guardian or legal representative.
Notwithstanding the foregoing, the Committee may set forth in the Agreement
evidencing an Option (other than an Incentive Stock Option) at the time of grant
or thereafter, that the Option may be transferred to members of the Optionee's
immediate family, to trusts solely for the benefit of such immediate family
members and to partnerships in which such family members and/or trusts are the
only partners. Following transfer, for purposes of this Plan, a transferee of an
Option shall be deemed to be the Optionee; provided that the Option shall be
exercisable by the transferee only to the extent and for such periods that the
Option would have been exercisable if held by the original Optionee. For this
purpose, immediate family means the Optionee's spouse, parents, children,
stepchildren and grandchildren and the spouses of such parents, children,
stepchildren and grandchildren. The terms of an Option shall be final, binding
and conclusive upon the beneficiaries, executors, administrators, heirs and
successors of the Optionee.

                  7.3 METHOD OF EXERCISE.

                           (a) The exercise of an Option shall be made only by a
written notice delivered in person or by mail to the Secretary of the Company at
the Company's principal executive office, specifying the number of Shares to be
purchased and, to the extent applicable, accompanied by payment therefor and
otherwise in accordance with such procedures which may be approved by the
Committee from time to time, and in accordance with the Agreement pursuant to
which the Option was granted; PROVIDED, HOWEVER, that Options may not be
exercised by an Optionee for twelve months following a hardship distribution to
the Optionee, to the extent such exercise is prohibited under Treasury
Regulation ss. 1.401(k)-1(d)(2)(iv)(B)(4). The purchase price for any Shares
purchased pursuant to the exercise of an Option shall be paid, as determined by
the Committee in its sole discretion, by any one or a combination of the
following: (a) delivery of cash or a check to the order of the Company or (b)
transferring to the Company Shares that have been held by the Optionee for at
least six (6) months (or such lesser period as may be permitted by the
Committee) prior to the exercise of the Option



                                      -17-
<PAGE>


and that have a Fair Market Value equal in amount to the purchase price, such
transfer to be upon such terms and conditions as determined by the Committee. In
addition, both Options and Formula Options may be exercised through a registered
broker-dealer pursuant to such cashless exercise procedures which are, from time
to time, deemed acceptable by the Committee. Any Shares transferred to the
Company as payment of the purchase price under an Option shall be valued at
their Fair Market Value on the day preceding the date of exercise of such
Option. If requested by the Committee, the Optionee shall deliver the Agreement
evidencing the Option to the Secretary of the Company who shall endorse thereon
a notation of such exercise and return such Agreement to the Optionee. No
fractional Shares (or cash in lieu thereof) shall be issued upon exercise of an
Option and the number of Shares that may be purchased upon exercise shall be
rounded to the nearest number of whole Shares.

                           (b) If the Fair Market Value of the Shares with
respect to which the Option is being exercised exceeds the purchase price of
such Option, an Optionee may, instead of exercising an Option as provided in
Section 7.3(a), request that the Committee authorize payment to the Optionee of
the difference between the Fair Market Value of part or all of the Shares which
are the subject of the Option and the purchase price of the Option, such
difference to be determined as of the date the Committee receives the request
from the Optionee. The Committee, in its sole discretion, may grant or deny such
a request from an Optionee with respect to part or all of the Shares as to which
the Option is then exercisable and, to the extent granted, shall direct the
Company to make the payment to the Optionee either in cash or in Shares or in
any combination thereof; PROVIDED, HOWEVER, that the payment in Shares shall be
based upon the Fair Market Value of Shares as of the date the Committee received
the request from the Optionee. An Option shall be deemed to have been exercised
and shall be canceled to the extent that the Committee grants a request pursuant
to this Section 7.3(b).

                  7.4 RIGHTS OF OPTIONEES. No Optionee shall be deemed for any
purpose to be the owner of any Shares subject to any Option unless and until (a)
the Option shall have been exercised pursuant to the terms thereof, (b) the
Company shall have issued and delivered Shares to the Optionee, and (c) the
Optionee's name shall have been entered as a stockholder of record on the books
of the Company. Thereupon, the Optionee shall have full voting, dividend and
other ownership rights with respect to such Shares, subject to such terms and
conditions as may be set forth in the applicable Agreement.

                  7.5 EFFECT OF CHANGE IN CONTROL.

                           (a) Notwithstanding anything contained in Sections 5
or 6 to the contrary, in the event of a Change in Control, the Committee, in its
sole discretion, may provide in writing in connection with, or in contemplation
of, any such Change in Control for any or all of the following alternatives
(separately or in any combination): (i) for the



                                      -18-
<PAGE>


assumption by the Successor Corporation of the Options theretofore granted or
the substitution by such corporation for such Options of new options covering
the stock of the Successor Corporation with appropriate adjustments as to the
number and kinds of shares and the purchase prices; (ii) for the continuation of
the Plan in which event the Plan and the Options shall continue under such terms
as may be provided; (iii) for the accelerated vesting of the Options; or (iv)
for the payment in cash upon the surrender to the Company for cancellation of
any Option or portion of an Option to the extent not yet exercised in an amount
equal to the excess, if any, of (i) (A) in the case of a Nonqualified Stock
Option, the greater of (1) the Fair Market Value, on the date preceding the date
of surrender, of the Shares subject to the Option or portion thereof surrendered
or (2) the Adjusted Fair Market Value of the Shares subject to the Option or
portion thereof surrendered or (B) in the case of an Incentive Stock Option, the
Fair Market Value, on the date preceding the date of surrender, of the Shares
subject to the Option or portion thereof surrendered, over (ii) the aggregate
purchase price for such Shares under the Option or portion thereof surrendered.
Any vesting of an Option or portion of an Option pursuant to this Section 7.5(a)
or surrender of an Option for a cash payment shall be conditioned upon the
consummation of the Change in Control and shall be effective only immediately
before the consummation of the Change in Control. Upon consummation of the
Change in Control, the Plan and all outstanding but unexercised Options shall
terminate, except to the extent provision is made in writing in connection with
such transaction for continuation of the Plan, or the assumption or substitution
of such Options. The Committee shall send written notice of an event that will
result in such a termination to all individuals who hold Options not later than
the time at which the Company gives notice thereof to its stockholders.

                           (b) To the extent set forth in the applicable
Agreement, if, as a result of a Change in Control transaction, an Option
intended to qualify as an Incentive Stock Option fails to so qualify SOLELY
because of the failure to meet the holding requirements of Code Section
422(a)(1) (a "Disqualifying Disposition"), the Company shall make a cash payment
to the Optionee equal to the amount which will, after taking into account all
taxes imposed on the Disqualifying Disposition and the receipt of such payment,
leave the Optionee in the same after-tax position the Optionee would have been
in had the Code Section 422(a)(1) holding requirements been met at the time of
the Disqualifying Disposition; PROVIDED, HOWEVER, that no payment described in
this Section shall exceed the Tax Benefit to the Company resulting from
deductions relating to ordinary income recognized by the Optionee as a result of
the Disqualifying Disposition and the receipt of such payment. The payment
described in this Section shall be made by the Company within thirty (30) days
of the filing by the



                                      -19-
<PAGE>


Company of the federal tax return which includes the tax items associated with
the income recognized by the Optionee as a result of the Disqualifying
Disposition (or, if the Tax Benefit described in the preceding sentence is not
realized until a later year, within thirty (30) days of the filing by the
Company of the federal tax return with respect to which such Tax Benefit is
realized); PROVIDED, HOWEVER, that if more than one Optionee is entitled to a
cash payment pursuant to this Section 7.5(b) in any single tax year and the Tax
Benefit realized by the Company in such year with respect to all such Optionees
is less than the aggregate amount of the payments due to such Optionees
hereunder, then (i) each such Optionee shall receive a portion of such cash
payment equal to an amount determined by multiplying the amount of the Tax
Benefit realized by the Company in such year by a fraction the numerator of
which is equal to the amount of payment due to such Optionee and the denominator
of which is equal to the aggregate amount due to all such Optionees entitled to
a payment hereunder, and (ii) subject to further application of this proviso,
shall be entitled to receive the remaining portion within thirty (30) days of
the filing by the Company of the federal tax return with respect to which such
Tax Benefit is realized.

                           (c) To the extent set forth in the applicable
Agreement and provided that an Optionee is not entitled to payment under Section
7.5(b) hereof, if, as a result of a Change in Control transaction, an Option
intended to qualify as an Incentive Stock Option fails to so qualify SOLELY
because the vesting of the Option is accelerated pursuant to Section 7.5(a) and
such acceleration causes the aggregate fair market value (determined at the time
the Option is granted) of the Shares with respect to which Options are
exercisable for the first time by an Optionee during the calendar year in which
such vesting occurs to exceed $100,000, within the meaning of Code Section
422(d) (a "Disqualified Option"), then, upon exercise of such Disqualified
Option, the Company shall make a cash payment to the Optionee equal to the
amount which will, after taking into account all taxes imposed on the exercise
of such Disqualified Option and the receipt of such payment, leave the Optionee
in the same after-tax position the Optionee would have been in had the
Disqualified Option continued to qualify as an Incentive Stock Option on the
date of exercise and the Optionee sold the Shares received upon exercise of the
Option at their Fair Market Value on the date of exercise; PROVIDED, HOWEVER,
that no payment described in this Section shall exceed the Tax Benefit to the
Company resulting from deductions relating to ordinary income recognized by the
Optionee as a result of exercising the Disqualified Option and the receipt of
such payment. The payment described in this Section shall be made by the Company
within thirty (30) days of the filing by the Company of the federal tax return
which includes the tax items associated with the income recognized by the
Optionee as a result of exercising the Disqualified Option (or, if the Tax
Benefit described in the preceding sentence is not realized until a later year,
within thirty (30) days of the filing by the Company of the federal tax return
with respect to which such Tax Benefit is realized); PROVIDED, HOWEVER, that if
more than one Optionee is entitled to a cash payment pursuant to this Section
7.5(c) in any single tax year and the Tax Benefit realized by the Company in
such year with respect to all such Optionees is less than the aggregate amount
of the payments due to such Optionees hereunder, then (i) each such Optionee
shall receive a portion of such cash payment equal



                                      -20-
<PAGE>


to an amount determined by multiplying the amount of the Tax Benefit realized by
the Company in such year by a fraction the numerator of which is equal to the
amount of payment due to such Optionee and the denominator of which is equal to
the aggregate amount due to all such Optionees entitled to a payment hereunder,
and (ii) subject to further application of this proviso, shall be entitled to
receive the remaining portion within thirty (30) days of the filing by the
Company of the federal tax return with respect to which such Tax Benefit is
realized.

         8.       STOCK APPRECIATION RIGHTS.

                  The Committee may in its sole discretion, either alone or in
connection with the grant of an Option, grant Stock Appreciation Rights in
accordance with the Plan, the terms and conditions of which shall be set forth
in an Agreement. If granted in connection with an Option, a Stock Appreciation
Right shall cover the same Shares covered by the Option (or such lesser number
of Shares as the Committee may determine) and shall, except as provided in this
Section 8, be subject to the same terms and conditions as the related Option.

                  8.1 TIME OF GRANT. A Stock Appreciation Right may be granted
(a) at any time if unrelated to an Option, or (b) if related to an Option,
either at the time of grant, or (except in the case of an Incentive Stock
Option) at any time thereafter during the term of the Option.

                  8.2 STOCK APPRECIATION RIGHT RELATED TO AN OPTION.

                           (a) EXERCISE. Subject to Section 8.9, a Stock
Appreciation Right granted in connection with an Option shall be exercisable at
such time or times and only to the extent that the related Options are
exercisable (including, without limitation, exercisability upon Termination of
Employment or a Change in Control), and will not be transferable except to the
extent the related Option may be transferable. A Stock Appreciation Right
granted in connection with an Incentive Stock Option shall expire no later than
the expiration of the related Incentive Stock Option and shall be exercisable
only if the Fair Market Value of a Share on the date of exercise exceeds the
purchase price of the Option specified in the related Incentive Stock Option
Agreement.

                           (b) TREATMENT OF RELATED OPTIONS AND STOCK
APPRECIATION RIGHTS UPON EXERCISE. Upon the exercise of a Stock Appreciation
Right granted in connection with an Option, the Option shall be canceled to the
extent of the number of Shares as to which the Stock Appreciation Right is
exercised, and upon the exercise of an Option granted in connection with a Stock
Appreciation Right, the Stock Appreciation Right



                                      -21-
<PAGE>


shall be canceled to the extent of the number of Shares as to which the Option
is exercised or surrendered.

                  8.3 STOCK APPRECIATION RIGHT UNRELATED TO AN OPTION.

                           (a) TERMS. Stock Appreciation Rights unrelated to
Options shall contain such terms and conditions as to exercisability (subject to
Section 8.9), vesting and duration as the Committee shall determine, but in no
event shall they have a term of greater than ten (10) years; PROVIDED, HOWEVER,
that the Committee may provide that Stock Appreciation right may, upon the death
of the Grantee, be exercised for up to one (1) year following the date of the
Grantee's death even if such period extends beyond ten (10) years from the date
the Stock Appreciation Right is granted.

                           (b) TERMINATION. Subject to Section 13 and except as
provided in Section 8.9, and unless otherwise provided by the Committee, in its
sole discretion, in the applicable Agreement, upon a Grantee's Termination of
Employment, a Stock Appreciation Right shall be exercisable by the Grantee to
the same extent that an Option would be exercisable by an Optionee upon the
Optionee's Termination of Employment under the provisions of Section 5.5;
PROVIDED, HOWEVER, no Stock Appreciation Right may be exercised after the
expiration date specified for the particular Stock Appreciation Right in the
applicable Agreement.

                  8.4 AMOUNT PAYABLE. Subject to Section 8.7, upon the exercise
of a Stock Appreciation Right, the Grantee shall be entitled to receive an
amount determined by multiplying (x) the excess of the Fair Market Value of a
Share on the date preceding the date of exercise of such Stock Appreciation
Right over (A) in the case of a Stock Appreciation Right granted in connection
with an Option, the per Share purchase price under the related Option, or (B) in
the case of a Stock Appreciation Right unrelated to an Option, the Fair Market
Value of a Share on the date the Stock Appreciation Right was granted, by (y)
the number of Shares as to which such Stock Appreciation Right is being
exercised. Notwithstanding the foregoing, the Committee may limit in any manner
the amount payable with respect to any Stock Appreciation Right by including
such a limit in the Agreement evidencing the Stock Appreciation Right at the
time it is granted.

                  8.5 NON-TRANSFERABILITY. No Stock Appreciation Right shall be
transferable by the Grantee to whom it was granted otherwise than by will or by
the laws of descent and distribution or, in the Committee's sole discretion,
(except in the case of a Stock Appreciation Right granted in connection with an
Incentive Stock Option), to a spouse or former spouse in a transfer described in
Section 1041(a) of the Code (a "Code 1041 Transfer"), and, except with respect
to a Stock Appreciation Right transferred pursuant to a Code 1041 Transfer, such
Stock Appreciation Right shall be exercisable during the lifetime of such
Grantee only by the Grantee or his or her guardian or legal



                                      -22-
<PAGE>


representative. The terms of such Stock Appreciation Right shall be final,
binding and conclusive upon the beneficiaries, executors, administrators, heirs
and successors of the Grantee.

                  8.6 METHOD OF EXERCISE. Stock Appreciation Rights shall be
exercised by a Grantee only by a written notice delivered in person or by mail
to the Secretary of the Company at the Company's principal executive office,
specifying the number of Shares with respect to which the Stock Appreciation
Right is being exercised. If requested by the Committee, the Grantee shall
deliver the Agreement evidencing the Stock Appreciation Right being exercised
and the Agreement evidencing any related Option to the Secretary of the Company
who shall endorse thereon a notation of such exercise and return such Agreement
to the Grantee.

                  8.7 FORM OF PAYMENT. Payment of the amount determined under
Section 8.4 may be made in the sole discretion of the Committee solely in whole
Shares in a number determined at their Fair Market Value on the date preceding
the date of exercise of the Stock Appreciation Right, or solely in cash, or in a
combination of cash and Shares. If the Committee decides to make full payment in
Shares and the amount payable results in a fractional Share, no fractional
Shares (or cash in lieu thereof) shall be issued upon the exercise of the Stock
Appreciation Right and the number of Shares that will be delivered shall be
rounded to the nearest number of whole Shares.

                  8.8 MODIFICATION. No modification of an Award shall adversely
alter or impair any rights or obligations under the Agreement without the
Grantee's consent.

                  8.9 EFFECT OF CHANGE IN CONTROL. Notwithstanding anything
contained in this Section 8 to the contrary, in the event of a Change in
Control, the Committee, in its sole discretion, may provide in writing in
connection with, or in contemplation of, any such Change in Control for any or
all of the following alternatives (separately or in any combination): (i) for
the assumption by the Successor Corporation of the Stock Appreciation Rights
theretofore granted or the substitution by such corporation for such Stock
Appreciation Rights of new stock appreciation rights covering the stock of the
Successor Corporation with appropriate adjustments as to the number and kinds of
shares and the purchase prices; (ii) for the continuation of the Plan in which
event the Plan and the Stock Appreciation Rights shall continue under such terms
as may be provided; (iii) for the accelerated vesting of the Stock Appreciation
Rights; or (iv) with respect to a Stock Appreciation Right unrelated to an
Option, for the payment in cash upon the surrender to the Company for
cancellation of any such Stock Appreciation Right or portion of a Stock
Appreciation Right to the extent not yet exercised in an amount equal to the
excess, if any, of (A) the greater of (i) the Fair Market Value, on the date
preceding the date of exercise, of the underlying Shares subject to the Stock
Appreciation Right or portion thereof exercised and (ii) the Adjusted Fair
Market Value, on the date preceding



                                      -23-
<PAGE>


the date of exercise, of the Shares over (B) the aggregate Fair Market Value, on
the date the Stock Appreciation Right was granted, of the Shares subject to the
Stock Appreciation Right or portion thereof exercised. Any vesting of Stock
Appreciation Rights pursuant to this Section 8.9 or surrender of a Stock
Appreciation Right for a cash payment shall be conditioned upon the consummation
of the Change in Control and shall be effective only immediately before the
consummation of the Change in Control. Upon consummation of the Change in
Control, the Plan and all outstanding but unexercised Stock Appreciation Rights
shall terminate, except to the extent provision is made in writing in connection
with such transaction for the continuation of the Plan, or the assumption or
substitution of such Stock Appreciation Rights. The Committee shall send written
notice of an event that will result in such a termination to all individuals who
hold Stock Appreciation Rights not later than the time at which the Company
gives notice thereof to its stockholders.

         9.       DIVIDEND EQUIVALENT RIGHTS.

                  The Committee may in its sole discretion grant Dividend
Equivalent Rights to Eligible Individuals in tandem with an Option or Award or
as a separate Award. The terms and conditions (including, without limitation,
terms and conditions relating to a Change in Control) applicable to each
Dividend Equivalent Right shall be specified in the Agreement under which the
Dividend Equivalent Right is granted. In the sole discretion of the Committee,
amounts payable in respect of Dividend Equivalent Rights may be payable
currently or deferred until the lapsing of restrictions on such Dividend
Equivalent Rights or until the vesting, exercise, payment, settlement or other
lapse of restrictions on the Option or Award to which the Dividend Equivalent
Rights relate. In the event that the amount payable in respect of Dividend
Equivalent Rights are to be deferred, the Committee shall determine whether such
amounts are to be held in cash or reinvested in Shares or deemed (notionally) to
be reinvested in Shares. If amounts payable in respect of Dividend Equivalent
Rights are to be held in cash, there may be credited at the end of each year (or
portion thereof) interest on the amount of the account at the beginning of the
year at a rate per annum as the Committee, in its sole discretion, may
determine. In the sole discretion of the Committee, Dividend Equivalent Rights
may be settled in cash or Shares or a combination thereof, in a single
installment or multiple installments. With respect to Dividend Equivalent Rights
granted in tandem with an Option, the Agreement may provide that the Optionee
may elect to have amounts payable in respect of such Dividend Equivalent Rights
applied against the purchase price of such Option. To the extent necessary for
any Dividend Equivalent Right intended to qualify as Performance-Based
Compensation under Section 162(m) of the Code to so qualify, the terms and
conditions of the Dividend Equivalent Right shall be such that payment of the
Dividend Equivalent Right is contingent upon attainment of specified Performance
Objectives



                                      -24-
<PAGE>


within the Performance Cycle, as provided for in Section 11, and such Dividend
Equivalent Right shall be treated as a Performance Award for purposes of
Sections 11 and 16.

         10.      RESTRICTED STOCK.

                  10.1 GRANT. The Committee may in its sole discretion grant
Awards to Eligible Individuals of Restricted Stock, which shall be evidenced by
an Agreement between the Company and the Grantee. Each Agreement shall contain
such restrictions, terms and conditions as the Committee may, in its sole
discretion, determine and (without limiting the generality of the foregoing)
such Agreements may require that an appropriate legend be placed on Share
certificates. Awards of Restricted Stock shall be subject to the terms and
provisions set forth below in this Section 10.

                  10.2 RIGHTS OF GRANTEE. Shares of Restricted Stock granted
pursuant to an Award hereunder shall be issued in the name of the Grantee as
soon as reasonably practicable after the Award is granted PROVIDED that the
Grantee has executed an Agreement evidencing the Award, the appropriate blank
stock powers and, in the sole discretion of the Committee, an escrow agreement
and any other documents which the Committee may require as a condition to the
issuance of such Shares. If a Grantee shall fail to execute the Agreement
evidencing a Restricted Stock Award, the appropriate blank stock powers, an
escrow agreement or any other documents which the Committee may require within
the time period prescribed by the Committee at the time the Award is granted,
the Award shall be null and void. At the sole discretion of the Committee,
Shares issued in connection with a Restricted Stock Award shall be deposited
together with the stock powers with an escrow agent (which may be the Company)
designated by the Committee. Unless the Committee determines otherwise and as
set forth in the Agreement, upon delivery of the Shares to the escrow agent, the
Grantee shall have all of the rights of a stockholder with respect to such
Shares, including the right to vote the Shares and to receive all dividends or
other distributions paid or made with respect to the Shares.

                  10.3 NON-TRANSFERABILITY. Until all restrictions upon the
Shares of Restricted Stock awarded to a Grantee shall have lapsed in the manner
set forth in Section 10.4, such Shares shall not be sold, transferred or
otherwise disposed of and shall not be pledged or otherwise hypothecated, nor
shall they be delivered to the Grantee.

                  10.4 LAPSE OF RESTRICTIONS.

                           (a) GENERALLY. Subject to Section 10.4(b),
restrictions upon Shares of Restricted Stock awarded hereunder shall lapse at
such time or times and on such terms and conditions as the Committee may
determine; PROVIDED, HOWEVER, that



                                      -25-
<PAGE>


except in the case of Shares of Restricted Stock issued in full or partial
settlement of another Award or other earned compensation, such restrictions
shall not fully lapse prior to the third anniversary of the date on which such
Shares of Restricted Stock were granted. The Agreement evidencing the Award
shall set forth any such restrictions.

                           (b) EFFECT OF CHANGE IN CONTROL. Notwithstanding
anything in this Section 10 to the contrary, in the event of a Change in
Control, the Committee, in its sole discretion, may provide in writing in
connection with, or in contemplation of, any such Change in Control for any or
all of the following alternatives (separately or in any combination): (i) for
the assumption by the Successor Corporation of the shares of Restricted Stock
theretofore granted or the substitution by such corporation for such shares of
Restricted Stock of new shares of restricted stock of the Successor Corporation
with appropriate adjustments as to the number and kinds of shares; (ii) for the
continuation of the Plan in which event the Plan and the shares of Restricted
Stock shall continue under such terms as may be provided; or (iii) for the lapse
of all restrictions upon the shares of Restricted Stock. Any vesting of shares
of Restricted Stock pursuant to this Section 10.5(b) shall be conditioned upon
the consummation of the Change in Control and shall be effective only
immediately before the consummation of the Change in Control.

                  10.5 TERMS OF RESTRICTED STOCK.

                           (a) FORFEITURE OF RESTRICTED STOCK. Subject to
Sections 10.4(b), 10.5(b) and 13, all Restricted Stock shall be forfeited and
returned to the Company and all rights of the Grantee with respect to such
Restricted Stock shall terminate unless the Grantee continues in the service of
the Company as an employee or director until the expiration of the forfeiture
period for such Restricted Stock and satisfies any and all other conditions set
forth in the Agreement. The Committee, in its sole discretion, shall determine
the forfeiture period (which may, but need not, lapse in installments) and any
other terms and conditions applicable with respect to any Restricted Stock
Award.

                           (b) WAIVER OF FORFEITURE PERIOD. Notwithstanding
anything contained in this Section 10 to the contrary, the Committee may, in its
sole discretion, waive the forfeiture period and any other conditions set forth
in any Agreement under appropriate circumstances (including, without limitation,
the death, Disability or retirement of the Grantee or a material change in
circumstances arising after the date of grant) and subject to such terms and
conditions (including, without limitation, forfeiture of a proportionate number
of the Restricted Stock) as the Committee shall deem appropriate, PROVIDED that
the Grantee shall at that time have completed at least one (1) year of
employment or service after the date of grant.



                                      -26-
<PAGE>


                  10.6 MODIFICATION OR SUBSTITUTION. Subject to the terms of the
Plan, including, without limitation, Section 16, the Committee may modify
outstanding Awards of Restricted Stock or accept the surrender of outstanding
shares of Restricted Stock (to the extent the restrictions on such Shares have
not yet lapsed) and grant new Awards in substitution for them. Notwithstanding
the foregoing, no modification of an Award shall adversely alter or impair any
rights or obligations under the Agreement without the Grantee's consent.

                  10.7 TREATMENT OF DIVIDENDS. At the time an Award of Shares of
Restricted Stock is granted, the Committee may, in its sole discretion,
determine that the payment to the Grantee of dividends, or a specified portion
thereof, declared or paid on such Shares by the Company shall be (a) deferred
until the lapsing of the restrictions imposed upon such Shares and (b) held by
the Company for the account of the Grantee until such time. In the event that
dividends are to be deferred, the Committee shall determine whether such
dividends are to be reinvested in Shares (which shall be held as additional
Shares of Restricted Stock) or held in cash. If deferred dividends are to be
held in cash, there may be credited at the end of each year (or portion thereof)
interest on the amount of the account at the beginning of the year at a rate per
annum as the Committee, in its sole discretion, may determine. Payment of
deferred dividends in respect of Shares of Restricted Stock (whether held in
cash or as additional Shares of Restricted Stock), together with interest
accrued thereon, if any, shall be made upon the lapsing of restrictions imposed
on the Shares in respect of which the deferred dividends were paid, and any
dividends deferred (together with any interest accrued thereon) in respect of
any Shares of Restricted Stock shall be forfeited upon the forfeiture of such
Shares.

                  10.8 DELIVERY OF SHARES. Upon the lapse of the restrictions on
Shares of Restricted Stock, the Committee shall cause a stock certificate to be
delivered to the Grantee with respect to such Shares, free of all restrictions
hereunder.

         11.      PERFORMANCE AWARDS.

                  11.1 PERFORMANCE OBJECTIVES

                           (a) ESTABLISHMENT. Performance Objectives for
Performance Awards may be expressed in terms of (i) earnings per Share, (ii)
Share price, (iii) pre-tax profits, (iv) net earnings, (v) return on equity or
assets, (vi) revenues, (vii) EBITDA (earnings before interest, taxes,
depreciation and amortization), (viii) market share, or market penetration, (ix)
any combination of the foregoing or (x) prior to the end of the Transition
Period, such other criteria as the Committee may determine, and may be
determined before or after accounting changes, special charges, foreign currency
effects, acquisitions, divestitures, or other extraordinary events as determined
by the Committee.



                                      -27-
<PAGE>


Performance Objectives may be in respect of the performance of the Company, any
of its Subsidiaries, any of its Divisions or any combination thereof.
Performance Objectives may be absolute or relative (to prior performance of the
Company or to the performance of one or more other entities or external indices)
and may be expressed in terms of a progression within a specified range. The
Performance Objectives with respect to a Performance Cycle shall be established
in writing by the Committee by the earlier of (x) the date on which a quarter of
the Performance Cycle has elapsed or (y) the date which is ninety (90) days
after the commencement of the Performance Cycle, and in any event while the
performance relating to the Performance Objectives remain substantially
uncertain.

                           (b) EFFECT OF CERTAIN EVENTS. At the time of the
granting of a Performance Award, or at any time thereafter, in either case to
the extent permitted under Section 162(m) of the Code and the regulations
thereunder without adversely affecting the treatment of the Performance Award as
Performance-Based Compensation, the Committee may provide for the manner in
which performance will be measured against the Performance Objectives (or may
adjust the Performance Objectives) to reflect the impact of specified corporate
transactions, accounting or tax law changes and other extraordinary or
nonrecurring events.

                           (c) DETERMINATION OF PERFORMANCE. Prior to the
vesting, payment, settlement or lapsing of any restrictions with respect to any
Performance Award that is intended to constitute Performance-Based Compensation
made to a Grantee who is subject to Section 162(m) of the Code, the Committee
shall certify in writing that the applicable Performance Objectives have been
satisfied.

                  11.2 PERFORMANCE UNITS. The Committee, in its sole discretion,
may grant Awards of Performance Units to Eligible Individuals, the terms and
conditions of which shall be set forth in an Agreement between the Company and
the Grantee. Performance Units may be denominated in Shares or a specified
dollar amount and, contingent upon the attainment of specified Performance
Objectives within the Performance Cycle, represent the right to receive payment
as provided in Section 11.2(b) of (i) in the case of Share-denominated
Performance Units, the Fair Market Value of a Share on the date the Performance
Unit was granted, the date the Performance Unit became vested or any other date
specified by the Committee, (ii) in the case of dollar-denominated Performance
Units, the specified dollar amount or (iii) a percentage (which may be more than
100%) of the amount described in clause (i) or (ii) depending on the level of
Performance Objective attainment; PROVIDED, HOWEVER, that, the Committee may at
the time a Performance Unit is granted specify a maximum amount payable in
respect of a vested Performance Unit. Each Agreement shall specify the number of
Performance Units to which it relates, the Performance Objectives which must be
satisfied in order for the



                                      -28-
<PAGE>


Performance Units to vest and the Performance Cycle within which such
Performance Objectives must be satisfied.

                           (a) VESTING AND FORFEITURE. Subject to Sections
11.1(c) and 11.4, Performance Units shall become vested in such installments
(which need not be equal) and at such times or times and on such terms,
conditions and satisfaction of Performance Objectives as the Committee may, in
its sole discretion, determine at the time an Award is granted.

                           (b) PAYMENT OF AWARDS. Subject to Section 11.1(c),
payment to Grantees in respect of vested Performance Units shall be made as soon
as practicable after the last day of the Performance Cycle to which such Award
relates unless the Agreement evidencing the Award provides for the deferral of
payment, in which event the terms and conditions of the deferral shall be set
forth in the Agreement. Subject to Section 11.4, such payments may be made
entirely in Shares valued at their Fair Market Value as of the day preceding the
date of payment or such other date specified by the Committee, entirely in cash,
or in such combination of Shares and cash as the Committee in its sole
discretion shall determine at any time prior to such payment; PROVIDED, however,
that if the Committee in its sole discretion determines to make such payment
entirely or partially in Shares of Restricted Stock, the Committee must
determine the extent to which such payment will be in Shares of Restricted Stock
and the terms of such Restricted Stock at the time the Award is granted.

                           (c) NON-TRANSFERABILITY. Until the vesting of
Performance Units, such Performance Units shall not be sold, transferred or
otherwise disposed of and shall not be pledged or otherwise hypothecated.

                  11.3 PERFORMANCE SHARES. The Committee, in its sole
discretion, may grant Awards of Performance Shares to Eligible Individuals, the
terms and conditions of which shall be set forth in an Agreement between the
Company and the Grantee. Each Agreement may require that an appropriate legend
be placed on Share certificates. Awards of Performance Shares shall be subject
to the following terms and provisions:

                           (a) RIGHTS OF GRANTEE. The Committee shall provide at
the time an Award of Performance Shares is made the time or times at which the
actual Shares represented by such Award shall be issued in the name of the
Grantee; PROVIDED, HOWEVER, that no Performance Shares shall be issued until the
Grantee has executed an Agreement evidencing the Award, the appropriate blank
stock powers and, in the sole discretion of the Committee, an escrow agreement
and any other documents which the Committee may require as a condition to the
issuance of such Performance Shares. If a Grantee shall fail to execute the
Agreement evidencing an Award of Performance Shares, the appropriate blank stock
powers, an escrow agreement and any other documents which the Committee



                                      -29-
<PAGE>


may require within the time period prescribed by the Committee at the time the
Award is granted, the Award shall be null and void. At the sole discretion of
the Committee, Shares issued in connection with an Award of Performance Shares
shall be deposited together with the stock powers with an escrow agent (which
may be the Company) designated by the Committee. Except as restricted by the
terms of the Agreement, upon delivery of the Shares to the escrow agent, the
Grantee shall have, in the sole discretion of the Committee, all of the rights
of a stockholder with respect to such Shares, including the right to vote the
Shares and to receive all dividends or other distributions paid or made with
respect to the Shares.

                           (b) NON-TRANSFERABILITY. Until any restrictions upon
the Performance Shares awarded to a Grantee shall have lapsed in the manner set
forth in Sections 11.3(c) or 11.4, such Performance Shares shall not be sold,
transferred or otherwise disposed of and shall not be pledged or otherwise
hypothecated, nor shall they be delivered to the Grantee. The Committee may also
impose such other restrictions and conditions on the Performance Shares, if any,
as it deems appropriate.

                           (c) LAPSE OF RESTRICTIONS. Subject to Sections
11.1(c) and 11.4, restrictions upon Performance Shares awarded hereunder shall
lapse and such Performance Shares shall become vested at such time or times and
on such terms, conditions and satisfaction of Performance Objectives as the
Committee may, in its sole discretion, determine at the time an Award is
granted.

                           (d) TREATMENT OF DIVIDENDS. At the time the Award of
Performance Shares is granted, the Committee may, in its sole discretion,
determine that the payment to the Grantee of dividends, or a specified portion
thereof, declared or paid on Shares represented by such Award which have been
issued by the Company to the Grantee shall be (i) deferred until the lapsing of
the restrictions imposed upon such Performance Shares and (ii) held by the
Company for the account of the Grantee until such time. In the event that
dividends are to be deferred, the Committee shall determine whether such
dividends are to be reinvested in Shares (which shall be held as additional
Performance Shares) or held in cash. If deferred dividends are to be held in
cash, there may be credited at the end of each year (or portion thereof)
interest on the amount of the account at the beginning of the year at a rate per
annum as the Committee, in its sole discretion, may determine. Payment of
deferred dividends in respect of Performance Shares (whether held in cash or in
additional Performance Shares), together with interest accrued thereon, if any,
shall be made upon the lapsing of restrictions imposed on the Performance Shares
in respect of which the deferred dividends were paid, and any dividends deferred
(together with any interest accrued thereon) in respect of any Performance
Shares shall be forfeited upon the forfeiture of such Performance Shares.



                                      -30-
<PAGE>


                           (e) DELIVERY OF SHARES. Upon the lapse of the
restrictions on Performance Shares awarded hereunder, the Committee shall cause
a stock certificate to be delivered to the Grantee with respect to such Shares,
free of all restrictions hereunder.

                  11.4 EFFECT OF CHANGE IN CONTROL. Notwithstanding anything in
this Section 11 to the contrary, in the event of a Change in Control, the
Committee, in its sole discretion, may provide in writing in connection with, or
in contemplation of, any such Change in Control for any or all of the following
alternatives (separately or in any combination): (i) for the assumption by the
Successor Corporation of the Performance Awards theretofore granted or the
substitution by such corporation for such Performance Awards of new performance
awards of the Successor Corporation with appropriate adjustments as to the
applicable performance objectives and, if necessary, the number and kinds of
shares; (ii) for the continuation of the Plan in which event the Plan and the
Performance Awards shall continue under such terms as may be provided; or (iii)
for the vesting of outstanding Performance Awards as if all Performance
Objectives had been satisfied at the maximum level and, in the case of
Performance Units which become vested as a result of a Change in Control, for a
payment which may be made entirely in Shares valued at their Fair Market Value
as of the day preceding the payment, entirely in cash, or in such combination of
Shares and cash as the Committee shall determine in its sole discretion at any
time prior to such payment; provided that such payment shall be made within ten
(10) business days after such Change in Control. Any vesting of Performance
Awards pursuant to this Section 11.4 shall be conditioned upon the consummation
of the Change in Control and shall be effective only immediately before the
consummation of the Change in Control.

                  11.5 TERMINATION. Except as provided in Section 13, and unless
otherwise provided by the Committee, in its sole discretion, in the applicable
Agreement, the following provisions shall apply to Performance Awards upon a
Termination of Employment:

                           (a) TERMINATION OF EMPLOYMENT PRIOR TO END OF
PERFORMANCE CYCLE. Except as provided in Sections 11.5(b) and (d), in the case
of a Grantee's Termination of Employment, prior to the end of a Performance
Cycle, the Grantee will not be entitled to any Performance Awards, and any
Performance Shares shall be forfeited.

                           (b) DISABILITY, RETIREMENT OR DEATH PRIOR TO END OF
PERFORMANCE CYCLE. Unless otherwise provided by the Committee, in its sole
discretion, in the Agreement, if a Grantee's Disability Date or Termination of
Employment by reason of retirement on or after the Grantee's Normal Retirement
Date or death occurs following at least twelve (12) months of participation in
any Performance Cycle, but prior to the end of a Performance Cycle, the Grantee
or such Grantee's Beneficiary, as the case may be,



                                      -31-
<PAGE>


shall be entitled to receive a pro-rata share of his or her Performance Award as
determined under Subsection (c).

                           (c) PRO-RATA PAYMENT.

                                    (I) PERFORMANCE UNITS. With respect to
Performance Units, the amount of any payment made to a Grantee (or Beneficiary)
under circumstances described in Section 11.5(b) will be the amount determined
by multiplying the amount of the Performance Units payable in Shares or dollars
which would have been earned, determined at the end of the Performance Cycle,
had such employment not been terminated, by a fraction, the numerator of which
is the number of whole months such Grantee was employed during the Performance
Cycle, and the denominator of which is the total number of months of the
Performance Cycle. Any such payment shall be made as soon as practicable after
the end of the respective Performance Cycle, and shall relate to attainment of
Performance Objectives over the entire Performance Cycle.

                                    (II) PERFORMANCE SHARES. With respect to
Performance Shares, the amount of Performance Shares held by a Grantee (or
Beneficiary) with respect to which restrictions shall lapse under circumstances
described in Section 11.5(b) will be the amount determined by multiplying the
amount of the Performance Shares with respect to which restrictions would have
lapsed, determined at the end of the Performance Cycle, had such employment not
been terminated, by a fraction, the numerator of which is the number of whole
months such Grantee was employed during the Performance Cycle, and the
denominator of which is the total number of months of the Performance Cycle. The
Committee shall determine the amount of Performance Shares with respect to which
restrictions shall lapse under this Section 11.5(c)(II) as soon as practicable
after the end of the respective Performance Cycle, and such determination shall
relate to attainment of Performance Objectives over the entire Performance
Cycle. At that time, all Performance Shares relating to that Performance Cycle
with respect to which restrictions shall not lapse shall be forfeited.

                           (d) OTHER EVENTS. Notwithstanding anything to the
contrary in this Section 11, the Committee may, in its sole discretion,
determine to pay all or any portion of a Performance Award to a Grantee who has
a Termination of Employment prior to the end of a Performance Cycle under
certain circumstances (including, without limitation, a material change in
circumstances arising after the date of grant) and subject to such terms and
conditions as the Committee shall deem appropriate, provided that the Grantee
shall have completed at his or her date of Termination of Employment at least
one (1) year of employment after the date of grant.

                           (e) TERMINATION OF EMPLOYMENT AFTER END OF
PERFORMANCE CYCLE. Subject to Section 11.5(f), in the case of a Grantee's
Termination of Employment after



                                      -32-
<PAGE>


the end of a Performance Cycle in which the applicable Performance Objectives
have been satisfied, the Grantee shall not be entitled to any Performance Awards
that have not yet vested as of the date of the Grantee's Termination of
Employment.

                           (f) WAIVER OF FORFEITURE. Notwithstanding anything to
the contrary in Section 11(e), in the case of a Grantee's Termination of
Employment after the end of a Performance Cycle in which the applicable
Performance Objectives have been satisfied, the Committee may, in its sole
discretion, waive the forfeiture of Performance Awards and any other conditions
set forth in any Agreement under appropriate circumstances (including, without
limitation, the death, Disability, or retirement of the Grantee or a material
change in circumstances arising after the date of grant) and subject to such
terms and conditions as the Committee shall deem appropriate.

                  11.6 MODIFICATION OR SUBSTITUTION. Subject to the terms of the
Plan, including, without limitation, Section 16, the Committee may modify
outstanding Performance Awards or accept the surrender of outstanding
Performance Awards and grant new Performance Awards in substitution for them.
Notwithstanding the foregoing, no modification of a Performance Award shall
adversely alter or impair any rights or obligations under the Agreement without
the Grantee's consent.

         12.      OTHER SHARE BASED AWARDS.

                  12.1 SHARE AWARDS. The Committee may, in its sole discretion,
grant a Share Award to any Eligible Individual on such terms and conditions as
the Committee may, in its sole discretion, determine. Share Awards may be made
as additional compensation for services rendered by the Eligible Individual or
may be in lieu of cash or other compensation to which the Eligible Individual is
entitled from the Company.

                  12.2 PHANTOM STOCK AWARDS.

                           (a) GRANT. The Committee may, in its sole discretion,
grant shares of Phantom Stock to any Eligible Individual. Such Phantom Stock
shall be subject to the terms and conditions established by the Committee and
set forth in the applicable Agreement.

                           (b) PAYMENT OF AWARDS. Upon the vesting of a Phantom
Stock Award, the Grantee shall be entitled to receive a cash payment in respect
of each share of Phantom Stock which shall be equal to the Fair Market Value of
a Share as of the date of the Phantom Stock Award was granted, or such other
date as determined by the Committee at the time the Phantom Stock Award was
granted. The Committee may, at the time a Phantom Stock Award is granted,
provide a limitation on the amount payable in respect of each share of Phantom
Stock. In lieu of a cash payment, the Committee



                                      -33-
<PAGE>


may settle Phantom Stock Awards with Shares having a Fair Market Value on the
date of vesting equal to the cash payment to which the Grantee has become
entitled.

         13. EMPLOYMENT AGREEMENT GOVERNS TERMINATION OF EMPLOYMENT. An
employment agreement, if applicable, between an Optionee or Grantee and the
Company shall govern with respect to the terms and conditions applicable to such
Option or Award upon a termination or change in the status of the employment of
the Optionee or Grantee, to the extent that such employment agreement provides
for terms and conditions that differ from the terms and conditions provided for
in the applicable Agreement or the Plan; PROVIDED, HOWEVER, that to the extent
necessary for an Option or Award intended to qualify as performance-based
compensation under Section 162(m) of the Code to so qualify, the terms of the
applicable Agreement or the Plan shall govern the Option or Award; and, PROVIDED
FURTHER, that the Committee shall have reviewed and, in its sole discretion,
approved the employment agreement.

         14.      ADJUSTMENT UPON CHANGES IN CAPITALIZATION.

                  (a) In the event of a Change in Capitalization, the Committee
shall conclusively determine the appropriate adjustments, if any, to (i) the
maximum number and class of Shares or other stock or securities with respect to
which Options or Awards may be granted under the Plan, (ii) the maximum number
and class of Shares or other stock or securities with respect to which Options
or Awards may be granted to any Eligible Individual during any calendar year
period, (iii) the number and class of Shares or other stock or securities which
are subject to outstanding Options or Awards granted under the Plan and the
purchase price therefor, if applicable, (iv) the number and class of Shares or
other securities in respect of which Formula Options are to be granted under
Section 6 and (v) the Performance Objectives.

                  (b) Any such adjustment in the Shares or other stock or
securities subject to outstanding Incentive Stock Options (including any
adjustments in the purchase price) shall be made in such manner as not to
constitute a modification as defined by Section 424(h)(3) of the Code and only
to the extent otherwise permitted by Sections 422 and 424 of the Code and, to
the extent necessary for any Option or Award intended to qualify as
Performance-Based Compensation to continue to so qualify, any such adjustment in
the Shares or other stock or securities subject to such Options and Awards shall
be made in such manner as to comply with Section 162(m) of the Code and the
regulations promulgated thereunder.

                  (c) If, by reason of a Change in Capitalization, a Grantee of
an Award shall be entitled to, or an Optionee shall be entitled to exercise an
Option with respect to, new, additional or different shares of stock or
securities of the Company or any other corporation, such new, additional or
different shares shall thereupon be subject to all of



                                      -34-
<PAGE>


the conditions, restrictions and performance criteria which were applicable to
the Shares subject to the Award or Option, as the case may be, prior to such
Change in Capitalization.

         15. EFFECT OF CERTAIN TRANSACTIONS. Subject to Sections 7.5, 8.9,
10.4(b) and 11.4 or as otherwise provided in an Agreement, in the event of (a)
the liquidation or dissolution of the Company or (b) a merger or consolidation
of the Company (a "Transaction"), the Plan and the Options and Awards issued
hereunder shall continue in effect in accordance with their respective terms,
except that following a Transaction each Optionee and Grantee shall be entitled
to receive in respect of each Share subject to any outstanding Options or
Awards, as the case may be, upon exercise of any Option or payment or transfer
in respect of any Award, the same number and kind of stock, securities, cash,
property or other consideration that each holder of a Share was entitled to
receive in the Transaction in respect of a Share; PROVIDED, HOWEVER, that such
stock, securities, cash, property, or other consideration shall remain subject
to all of the conditions, restrictions and performance criteria which were
applicable to the Options and Awards prior to such Transaction.

         16. INTERPRETATION. Following the required registration of any equity
security of the Company pursuant to Section 12 of the Exchange Act, unless
otherwise expressly stated in the relevant Agreement, each Option, Stock
Appreciation Right and Performance Award granted under the Plan to a "covered
employee" within the meaning of Section 162(m)(3) of the Code is intended to be
Performance-Based Compensation (except that, in the event of a Change in
Control, payment of Performance Awards to a Grantee who remains a "covered
employee" with respect to such payment may not qualify as Performance-Based
Compensation). The Committee shall not be entitled to exercise any discretion
otherwise authorized hereunder with respect to such Options or Awards if the
ability to exercise such discretion or the exercise of such discretion itself
would cause the compensation attributable to such Options or Awards to fail to
qualify as Performance-Based Compensation. Notwithstanding anything to the
contrary in the Plan, the provisions of the Plan may at any time be bifurcated
by the Board or the Committee in any manner so that certain provisions of the
Plan or any Performance Award intended (or required in order) to satisfy the
applicable requirements of Section 162(m) of the Code are only applicable to
persons whose compensation is subject to Section 162(m).

         17. POOLING TRANSACTIONS. Notwithstanding anything contained in the
Plan or any Agreement to the contrary, in the event of a Change in Control which
is also intended to constitute a Pooling Transaction, the Committee shall take
such actions, if any, as are specifically recommended by an independent
accounting firm retained by the Company to the extent reasonably necessary in
order to assure that the Pooling Transaction will qualify as such, including,
without limitation, (a) deferring the vesting,



                                      -35-
<PAGE>


exercise, payment, settlement or lapsing of restrictions with respect to any
Option or Award, (b) providing that the payment or settlement in respect of any
Option or Award be made in the form of cash, Shares or securities of a successor
or acquirer of the Company, or a combination of the foregoing, and (c) providing
for the extension of the term of any Option or Award to the extent necessary to
accommodate the foregoing, but not beyond the maximum term permitted for any
Option or Award.

         18.      EFFECTIVE DATE, TERMINATION AND AMENDMENT OF THE PLAN.

                  18.1 EFFECTIVE DATE. The effective date of this Plan shall be
the date the Plan is adopted by the Board, subject only to the approval of the
affirmative vote of the holders of a majority of the securities of the Company
present, or represented, and entitled to vote at a meeting of the stockholders
duly held in accordance with the applicable laws of the State of Delaware within
twelve (12) months of the adoption of the Plan by the Board.

                  18.2 PLAN AMENDMENT OR TERMINATION. The Plan shall terminate
on the day preceding the tenth anniversary of the date of its adoption by the
Board and no Option or Award may be granted thereafter. The Board may sooner
terminate the Plan and the Board may at any time and from time to time amend,
modify or suspend the Plan; PROVIDED, HOWEVER, that:

                           (a) no such amendment, modification, suspension or
termination shall impair or adversely alter any Options or Awards theretofore
granted under the Plan, except with the consent of the Optionee or Grantee, nor
shall any amendment, modification, suspension or termination deprive any
Optionee or Grantee of any Shares which he or she may have acquired through or
as a result of the Plan; and

                           (b) to the extent necessary under any applicable law,
regulation or exchange requirement no amendment shall be effective unless
approved by the stockholders of the Company in accordance with applicable law,
regulation or exchange requirement.

         19. NON-EXCLUSIVITY OF THE PLAN. The adoption of the Plan by the Board
shall not be construed as amending, modifying or rescinding any previously
approved incentive arrangement or as creating any limitations on the power of
the Board to adopt such other incentive arrangements as it may deem desirable,
including, without limitation, the granting of stock options otherwise than
under the Plan, and such arrangements may be either applicable generally or only
in specific cases.

         20. LIMITATION OF LIABILITY. As illustrative of the limitations of
liability of the Company, but not intended to be exhaustive thereof, nothing in
the Plan shall be construed to:

                  (a) give any person any right to be granted an Option or Award
other than at the sole discretion of the Committee;

                  (b) give any person any rights whatsoever with respect to
Shares except as specifically provided in the Plan;

                  (c) limit in any way the right of the Company or any
Subsidiary to terminate the employment of any person at any time; or

                  (d) be evidence of any agreement or understanding, expressed
or implied, that the Company will employ any person at any particular rate of
compensation or for any particular period of time.

         21.      REGULATIONS AND OTHER APPROVALS; GOVERNING LAW.

                  21.1 Except as to matters of federal law, the Plan and the
rights of all persons claiming hereunder shall be construed and determined in
accordance with the laws of the State of Delaware without giving effect to
conflicts of laws principles thereof.

                  21.2 The obligation of the Company to sell or deliver Shares
with respect to Options and Awards granted under the Plan shall be subject to
all applicable laws, rules and regulations, including all applicable federal and
state securities laws, and the obtaining of all such approvals by governmental
agencies as may be deemed necessary or appropriate by the Committee.

                  21.3 The Board may make such changes as may be necessary or
appropriate to comply with the rules and regulations of any government
authority, or to obtain for Eligible Individuals granted Incentive Stock Options
the tax benefits under the applicable provisions of the Code and regulations
promulgated thereunder.

                  21.4 Each Option and Award is subject to the requirement that,
if at any time the Committee determines, in its sole discretion, that the
listing, registration or qualification of Shares issuable pursuant to the Plan
is required by any securities exchange or under any state or federal law, or the
consent or approval of any governmental regulatory body is necessary or
desirable as a condition of, or in connection with, the grant of an Option or
Award or the issuance of Shares, no Options or Awards shall be granted or
payment made or Shares issued, in whole or in part, unless listing,
registration, qualification, consent or approval has been effected or obtained
free of any conditions as acceptable to the Committee.



                                      -37-
<PAGE>


                  21.5 Notwithstanding anything contained in the Plan or any
Agreement to the contrary, in the event that the disposition of Shares acquired
pursuant to the Plan is not covered by a then current registration statement
under the Securities Act of 1933, as amended (the "Securities Act"), and is not
otherwise exempt from such registration, such Shares shall be restricted against
transfer to the extent required by the Securities Act and Rule 144 or other
regulations thereunder. The Company may place on any certificate representing
any such Shares any legend deemed desirable by the Company's counsel to comply
with federal or state securities laws and the Committee may require any
individual receiving Shares pursuant to an Option or Award granted under the
Plan, as a condition precedent to receipt of such Shares, to represent and
warrant to the Company in writing that the Shares acquired by such individual
are acquired without a view to any distribution thereof and will not be sold or
transferred other than pursuant to an effective registration thereof under said
Act or pursuant to an exemption applicable under the Securities Act or the rules
and regulations promulgated thereunder.

         22.      MISCELLANEOUS.

                  22.1 MULTIPLE AGREEMENTS. The terms of each Option or Award
may differ from other Options or Awards granted under the Plan at the same time,
or at some other time. The Committee may also grant more than one Option or
Award to a given Eligible Individual during the term of the Plan, either in
addition to, or in substitution for, one or more Options or Awards previously
granted to that Eligible Individual.

                  22.2 CAPTIONS. The use of captions in this Plan or any
Agreement is for the convenience of reference only and shall not affect the
meaning of any provision of the Plan or such Agreement.

                  22.3 SEVERABILITY. Whenever possible, each provision of the
Plan or an Agreement shall be interpreted in such manner as to be effective and
valid under applicable law, but if any provision of the Plan or an Agreement
shall be held by a court of competent jurisdiction to be prohibited by or
invalid or unenforceable under applicable law, then (a) such provision shall be
deemed to be amended to accomplish the objectives of the provision as originally
written to the fullest extent permitted by law and (b) all other provisions of
the Plan or an Agreement shall remain in full force and effect.

                  22.4 WITHHOLDING OF TAXES.

                           (a) At such times as an Optionee or Grantee
recognizes taxable income in connection with the receipt of Shares or cash
hereunder (a "Taxable Event"), the Optionee or Grantee shall pay to the Company
an amount equal to the federal, state and local income taxes and other amounts
as may be required by law to be withheld by the Company in connection with the
Taxable Event (the "Withholding Taxes") prior to



                                      -38-
<PAGE>


the issuance, or release from escrow, of such Shares or the payment of such
cash. The Company shall have the right to deduct from any payment of cash to an
Optionee or Grantee an amount equal to the Withholding Taxes in satisfaction of
the obligation to pay Withholding Taxes. In satisfaction of the obligation to
pay Withholding Taxes to the Company, the Optionee or Grantee may make a written
election (the "Tax Election"), which may be accepted or rejected in the sole
discretion of the Committee, to have withheld a portion of the Shares then
issuable to him or her having an aggregate Fair Market Value, on the date
preceding the date of such issuance, equal to the Withholding Taxes.

                           (b) If an Optionee makes a disposition, within the
meaning of Section 424(c) of the Code and regulations promulgated thereunder, of
any Share or Shares issued to such Optionee pursuant to the exercise of an
Incentive Stock Option within the two-year period commencing on the day after
the date of the grant or within the one-year period commencing on the day after
the date of transfer of such Share or Shares to the Optionee pursuant to such
exercise, the Optionee shall, within ten (10) days of such disposition, notify
the Company thereof, by delivery of written notice to the Company at its
principal executive office.

                  22.5 POST-TRANSITION PERIOD. Any Option or Award granted under
the Plan after the expiration of the Transition Period which is intended to be
Performance-Based Compensation shall be subject to the approval of the material
terms of the Plan by a majority of the stockholders of the Company in accordance
with Section 162(m) of the Code and the regulations promulgated thereunder.

                                     FORM OF
                           SENIOR MANAGEMENT AGREEMENT

         THIS SENIOR MANAGEMENT AGREEMENT (this "AGREEMENT") is made as of
__________, between AppNet Systems, Inc., a Delaware corporation (the

         The Company and Executive desire to enter into an agreement pursuant to
which Executive will purchase, and the Company will sell, _____ shares of the
Company's Common Stock, par value $.0005 per share (the "EXECUTIVE STOCK").
Certain definitions are set forth in Section 9 of this Agreement.

         The execution and delivery of this Agreement by the Company and
Executive is related to the purchase of shares of Common Stock and shares of the
Company's Class A Preferred Stock, par value $.01 per share (the "CLASS A
PREFERRED") by Smart Technology, L.L.C. ("SMART TECHNOLOGY"), GTCR Golder
Rauner, L.L.C., a Delaware limited liability company ("GTCR" and, together with
Smart Technology, the "INVESTORS" and each an "INVESTOR") pursuant to a purchase
agreement between the Company and the Investors dated as of June 29, 1998 (the
"PURCHASE Agreement"). Certain provisions of this Agreement are intended for the
benefit of, and will be enforceable by, the Investors.

         The parties hereto agree as follows:

                     PROVISIONS RELATING TO EXECUTIVE STOCK

         1.       OWNERSHIP. Executive acknowledges that as of the date of this
Agreement, he owns beneficially and of record the Carried Stock free and clear
of all liens and encumbrances.

         2.       PURCHASE AND SALE OF EXECUTIVE STOCK.

                  (a) Upon execution of this Agreement, Executive will purchase,
and the Company will sell, _____ shares of Common Stock at a price of $____
per share. The Company will deliver to Executive the certificates representing
such Executive Stock, and Executive will deliver to the Company a check or wire
transfer of funds in the aggregate amount of $_____ and a promissory note in the
form of ANNEX A attached hereto in an aggregate principal amount of $_____ (the
"EXECUTIVE NOTE"). Executive's obligations under the Executive Note shall be
secured by a pledge of all of the shares of Common Stock purchased hereunder to
the Company and in connection therewith, Executive shall enter into a pledge
agreement in the form of ANNEX B attached hereto.

                  (b) Within 30 days after the date hereof, Executive will make
an effective election with the Internal Revenue Service under Section 83(b) of
the Internal Revenue Code and the regulations promulgated thereunder in the form
of ANNEX C attached hereto.

                  (c) In connection with the purchase and sale of the Executive
Stock hereunder, Executive represents and warrants to the Company that:


<PAGE>


                           (i) The Executive Stock to be acquired by Executive
pursuant to this Agreement will be acquired for Executive's own account and not
with a view to, or intention of, distribution thereof in violation of the
Securities Act, or any applicable state securities laws, and the Executive Stock
will not be disposed of in contravention of the Securities Act or any applicable
state securities laws.

                           (ii) Executive is an executive officer of the
Company, is sophisticated in financial matters and is able to evaluate the risks
and benefits of the investment in the Executive Stock.

                           (iii) Executive is able to bear the economic risk of
his investment in the Executive Stock for an indefinite period of time because
the Executive Stock has not been registered under the Securities Act and,
therefore, cannot be sold unless subsequently registered under the Securities
Act or an exemption from such registration is available.

                           (iv) Executive has had an opportunity to ask
questions and receive answers concerning the terms and conditions of the
offering of Executive Stock and has had full access to such other information
concerning the Company as he has requested.

                           (v) This Agreement constitutes the legal, valid and
binding obligation of Executive, enforceable in accordance with its terms, and
the execution, delivery and performance of this Agreement by Executive does not
and will not conflict with, violate or cause a breach of any agreement, contract
or instrument to which Executive is a party or any judgment, order or decree to
which Executive is subject.

                           (vi) Executive is a resident of the State of _____.

                  (d) As an inducement to the Company to issue the Executive
Stock to Executive, as a condition thereto, Executive acknowledges and agrees
that neither the issuance of the Executive Stock to Executive nor any provision
contained herein shall entitle Executive to remain in the employment of the
Company and its Subsidiaries or affect the right of the Company to terminate
Executive's employment at any time for any reason.

         3.       REPURCHASE OPTION.

                  (a) In the event that Executive ceases to be employed by the
Company and its Subsidiaries for any reason (the "SEPARATION"), the Executive
Stock (whether held by Executive or one or more of Executive's transferees,
other than the Company) will be subject to repurchase, in each case at the
option of the Company, the Investors and Ken S. Bajaj ("Bajaj") pursuant to the
terms and conditions set forth in this Section 3(a) (the "REPURCHASE OPTION"). A
percentage of the Executive Stock will be subject to repurchase at the
Executive's Original Cost for such shares, calculated in accordance with the
following schedule (the "ORIGINAL COST SHARES"):

The purchase price for the remaining shares of Executive Stock shall be the Fair
Market Value of such shares (the "FAIR MARKET VALUE SHARES").

                  (b) The Company may elect to purchase all or any portion of
the Original Cost Shares and the Fair Market Value Shares by delivering written
notice (the "REPURCHASE NOTICE") to the holder or holders of the Executive Stock
within 180 days after the Separation. The Repurchase Notice will set forth the
number of Original Cost Shares and Fair Market Value Shares to be acquired from
each holder, the aggregate consideration to be paid for such shares and the time
and place for the closing of the transaction. The number of shares to be
repurchased by the Company shall first be satisfied to the extent possible from
the shares of Executive Stock held by Executive at the time of delivery of the
Repurchase Notice. If the number of shares of Executive Stock then held by
Executive is less than the total number of shares of Executive Stock which the
Company has elected to purchase, the Company shall purchase the remaining shares
elected to be purchased from the other holder(s) of Executive Stock under this
Agreement, pro rata according to the number of shares of Executive Stock held by
such other holder(s) at the time of delivery of such Repurchase Notice
(determined as nearly as practicable to the nearest share). The number of
Original Cost Shares and Fair Market Value Shares to be repurchased hereunder
will be allocated among Executive and the other holders of Executive Stock (if
any) pro rata according to the number of shares of Executive Stock to be
purchased from such person.

                  (c) If for any reason the Company does not elect to purchase
all of the Executive Stock pursuant to the Repurchase Option, the Investors and
Bajaj shall be entitled to exercise the Repurchase Option for all or any portion
of the shares of Executive Stock that the Company has not elected to purchase
(the "AVAILABLE SHARES"). As soon as practicable after the Company has
determined that there will be Available Shares, but in any event within 150 days
after the Separation, the Company shall give written notice (the "OPTION
NOTICE") to the Investors and Bajaj setting forth the number of Available Shares
and the purchase price for the Available Shares. The Investors and Bajaj may
elect to purchase any or all of the Available Shares by



                                     3

<PAGE>


giving written notice to the Company within one month after the Option Notice
has been given by the Company. If the Investors and Bajaj elect to purchase an
aggregate number of shares greater than the number of Available Shares, the
Available Shares shall be allocated among the Investors and Bajaj based upon the
number of shares of Common Stock owned by each Investor and Bajaj on a fully
diluted basis (excluding, in the case of Bajaj, shares owned by him that are
subject to repurchase at cost). As soon as practicable, and in any event within
ten days, after the expiration of the one-month period set forth above, the
Company shall notify each holder of Executive Stock as to the number of shares
being purchased from such holder by the Investors and Bajaj (the "SUPPLEMENTAL
REPURCHASE NOTICE"). At the time the Company delivers the Supplemental
Repurchase Notice to the holder(s) of Executive Stock, the Company shall also
deliver written notice to the Investors and Bajaj setting forth the number of
shares the Investors and Bajaj are entitled to purchase, the aggregate purchase
price and the time and place of the closing of the transaction. The number of
Original Cost Shares and Fair Market Value Shares to be repurchased hereunder
shall be allocated among the Company, the Investors and Bajaj pro rata according
to the number of shares of Executive Stock to be purchased by each of them.
Notwithstanding the foregoing, the Investors and Bajaj shall not exercise their
Repurchase Option as to the Original Cost Shares pursuant to this Section 3(c)
if the Company has sufficient assets to fully exercise its Repurchase Option as
to the Original Cost Shares but has not exercised such right. Furthermore, if
the Investors and Bajaj repurchase any Original Cost Shares, they shall
contribute such Original Cost Shares to the Company in exchange for a promissory
note from the Company with an aggregate principal amount equal to the purchase
price paid for such shares, bearing interest (payable quarterly) at a rate per
annum equal to the prime rate as published in the WALL STREET JOURNAL from time
to time, and having a term of no longer than five years.

                  (d) The closing of the purchase of the Executive Stock
pursuant to the Repurchase Option shall take place on the date designated by the
Company in the Repurchase Notice or Supplemental Repurchase Notice, which date
shall not be more than one month nor less than five days after the delivery of
the later of either such notice to be delivered. The Company will pay for the
Executive Stock to be purchased by it pursuant to the Repurchase Option by first
offsetting amounts outstanding under any bona fide debts owed by Executive to
the Company and will pay the remainder of the purchase price by, at its option,
(A) a check or wire transfer of funds, or (B) a check or wire transfer of funds
for at least one-third of the purchase price, and a subordinated note or notes
payable in two equal annual installments beginning on each of the first and
second anniversary of the closing of such purchase and bearing interest (payable
quarterly) at a rate per annum equal to the prime rate as published in THE WALL
STREET JOURNAL from time to time in the aggregate amount of the remainder of the
purchase price for such shares. The Investors and Bajaj will pay for the
Executive Stock purchased by it by a check or wire transfer of funds. The
Company, the Investors and Bajaj will be entitled to receive customary
representations and warranties from the sellers regarding such sale and to
require that all sellers' signatures be guaranteed.

                  (e) Notwithstanding anything to the contrary contained in this
Agreement, all repurchases of Executive Stock by the Company shall be subject to
applicable restrictions contained in the Delaware General Corporation Law and in
the Company's and its Subsidiaries'



                                       4


<PAGE>


debt and equity financing agreements. If any such restrictions prohibit the
repurchase of Executive Stock hereunder which the Company is otherwise entitled
or required to make, the Company may make such repurchases as soon as it is
permitted to do so under such restrictions.

                  (f) Notwithstanding anything to the contrary contained in this
Agreement, if the Executive delivers the notice of objection described in the
definition of Fair Market Value, or if the Fair Market Value of a Fair Market
Value Share is otherwise determined to be an amount more than 10% greater than
the per share repurchase price for Fair Market Value Shares originally
determined by the Board, each of the Company, the Investors and Bajaj shall have
the right to revoke its or their exercise of the Repurchase Option for all or
any portion of the Executive Stock elected to be repurchased by it by delivering
notice of such revocation in writing to the holders of the Executive Stock
during (i) the thirty-day period beginning on the date the Company, the
Investors and Bajaj receive Executive's written notice of objection and (ii) the
thirty-day period beginning on the date the Company, the Investors and Bajaj are
given written notice that the Fair Market Value of a Fair Market Value Share was
finally determined to be an amount more than 10% greater than the per share
repurchase price for Fair Market Value Shares originally determined by the
Board.

                  (g) The provisions of this Section 3 shall terminate upon the
consummation of a Sale of the Company.

         4.       RESTRICTIONS ON TRANSFER OF EXECUTIVE STOCK.

                  (a) RETENTION OF EXECUTIVE STOCK. Until the fifth anniversary
of the date of this Agreement, Executive shall not sell, transfer, assign,
pledge or otherwise dispose of any interest in any shares of Executive Stock,
except pursuant to: (i) a Sale of the Company, (ii) Section 3 of this Agreement,
(iii) Section 4 of the Stockholders Agreement, (iv) a sale described in clause
(i) of the definition of "PUBLIC SALE," or (v) after a Public Offering, upon any
sale by the Investors or an Affiliate of the type described in clause (ii) of
the definition of "PUBLIC SALE" (a "RULE 144 SALE"), to the extent of the lesser
of (a) the number of shares of Executive Stock held by Executive that are not
subject to repurchase at Original Cost and (b) the number of shares of Executive
Stock held by Executive multiplied by a fraction, the numerator of which is the
number of shares of Common Stock sold by the Investors and their Affiliates in
the Rule 144 Sale and the denominator of which is the total number of shares of
Common Stock held by the Investors and their Affiliates immediately prior to
such sale.

                  (b) CERTAIN PERMITTED TRANSFERS. The restrictions in this
Section 4 will not apply with respect to (i) transfers of shares of Executive
Stock pursuant to applicable laws of descent and distribution or (ii) transfer
of shares of Executive Stock among Executive's Family Group; provided that such
restrictions will continue to be applicable to the Executive Stock after any
such transfer and the transferees of such Executive Stock have agreed in writing
to be bound by the provisions of this Agreement.

                  (c) TERMINATION OF RESTRICTIONS. The restrictions on the
Transfer of shares of Executive Stock set forth in this Section 4 will continue
with respect to each share of Executive Stock until the date on which such
Executive Stock has been transferred in a transaction


                                     5


<PAGE>


permitted by this Section 4 (except in a transaction contemplated by Section
4(b)); provided that in any event such restrictions will terminate on a Sale of
the Company.

         5.       ADDITIONAL RESTRICTIONS ON TRANSFER OF EXECUTIVE STOCK.

                  (a) LEGEND. The certificates representing the Executive Stock
will bear a legend in substantially the following form:

                  "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
                  "ACT"), AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF
                  AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR AN
                  EXEMPTION FROM REGISTRATION THEREUNDER. THE SECURITIES
                  REPRESENTED BY THIS CERTIFICATE ARE ALSO SUBJECT TO ADDITIONAL
                  RESTRICTIONS ON TRANSFER, CERTAIN REPURCHASE OPTIONS AND
                  CERTAIN OTHER AGREEMENTS SET FORTH IN A SENIOR MANAGEMENT
                  AGREEMENT BETWEEN THE COMPANY AND AN EXECUTIVE OF THE COMPANY
                  DATED AS OF JULY 31, 1998. A COPY OF SUCH AGREEMENT MAY BE
                  OBTAINED BY THE HOLDER HEREOF AT THE COMPANY'S PRINCIPAL PLACE
                  OF BUSINESS WITHOUT CHARGE."

                  (b) OPINION OF COUNSEL. No holder of Executive Stock may sell,
transfer or dispose of any Executive Stock (except pursuant to an effective
registration statement under the Securities Act) without first delivering to the
Company an opinion of counsel (reasonably acceptable in form and substance to
the Company) that neither registration nor qualification under the Securities
Act and applicable state securities laws is required in connection with such
transfer.

                        PROVISIONS RELATING TO EMPLOYMENT

         6. EMPLOYMENT. The Company agrees to employ Executive and Executive
accepts such employment for the period beginning as of the date hereof and
ending upon his separation pursuant to Section 6(c) hereof (the "EMPLOYMENT
PERIOD").

                  (a) POSITION AND DUTIES. During the Employment Period,
Executive shall serve as a Senior Vice President of the Company and shall have
such duties, responsibilities and authority as may be assigned by the President
and Chief Executive Officer, subject to the power of the Board to expand or
limit such duties, responsibilities and authority and to override actions of the
Senior Vice President. Executive shall report to the President and Chief
Executive Officer. Executive shall devote his best efforts and his full business
time and attention to the business and affairs of the Company and its
subsidiaries.

                  (b) SALARY, BONUS AND BENEFITS. During the Employment Period,
the Company will pay Executive a base salary (the "ANNUAL BASE SALARY") of
$200,000 per annum, subject to any increase as determined by the Board based
upon the Company's achievements of


                                     6


<PAGE>


budgetary and other objectives set by the Board. In addition, Executive shall be
eligible to receive a bonus of up to fifty (50%) percent of the Annual Base
Salary based upon the Company's achievement of budgetary and other objectives
set by the Board. Executive's Annual Base Salary for any partial year will be
prorated based upon the number of days elapsed in such year. In addition, during
the Employment Period, Executive will be entitled to such other benefits
approved by the Board and made available to the Company's senior management.

                  (c) SEPARATION. Executive's employment by the Company will
continue until Executive's resignation, disability (as determined by the Board
in its good faith judgment) or death or until the Board terminates Executive's
employment for any reason or without any reason. If the Employment Period is
terminated by the Board without Cause, subject to the provisions of this
Agreement, Executive shall be entitled to receive his Annual Base Salary and his
life insurance, medical insurance and disability insurance benefits (but no
bonuses or other fringe benefits) through the end of the Noncompete Period (as
defined below in Section 8, including any extensions pursuant to Section 8(a))
(such payment, the "SEVERANCE PAYMENT") payable in accordance with normal
payroll practices.

         7.       CONFIDENTIAL INFORMATION.

                  (a) Executive acknowledges that the Company and its
Subsidiaries are engaged in the business of acquiring businesses that provide
electronic commerce services and operating those businesses after their
acquisition (the "BUSINESS"). Executive further acknowledges that the Business
and its continued success depend upon the use and protection of a large body of
confidential and proprietary information, and that he holds a position of trust
and confidence by virtue of which he necessarily possesses, has access to and,
as a consequence of his signing this Agreement, will continue to possess and
have access to, highly valuable, confidential and proprietary information of the
Company and its Subsidiaries not known to the public in general, and that it
would be improper for him to make use of this information for the benefit of
himself and others. All of such confidential and proprietary information now
existing or to be developed in the future will be referred to in this Agreement
as "CONFIDENTIAL INFORMATION." This includes, without limitation, information
relating to the nature and operation of the Business, the persons, firms and
corporations which are customers or active prospects of the Company during
Executive's employment by the Company, the Company's development, transition and
transformation plans, methodology and methods of doing business, strategic,
acquisition, marketing and expansion plans, including plans regarding planned
and potential acquisitions and sales, financial and business plans, employee
lists, numbers and location of sales representatives, new and existing programs
and services (and those under development), prices and terms, customer service,
integration processes requirements, costs of providing service, support and
equipment and equipment maintenance costs. Confidential Information shall not
include any information that has become generally known to and available for use
by the public other than as a result of Executive's acts or omissions.

                  (b) Disclosure of any Confidential Information of the Company
shall not be prohibited if such disclosure is directly pursuant to a valid and
existing order of a court or other governmental body or agency within the United
States; provided, however, that (i) Executive



                                     7
<PAGE>


shall first have given prompt notice to the Company of any such possible or
prospective order (or proceeding pursuant to which any such order may result)
and (ii) Executive shall afford the Company a reasonable opportunity to prevent
or limit any such disclosure.

                  (c) During the Employment Period and at all times thereafter,
Executive will preserve and protect as confidential all of the Confidential
Information known to Executive or at any time in Executive's possession or
control. In addition, during the Employment Period and at all times thereafter,
Executive will not disclose to any unauthorized person or use for his own
account any of such Confidential Information without the Board's written
consent. Executive agrees to deliver to the Company at a Separation, or at any
other time the Company may request in writing, all memoranda, notes, plans,
records, reports and other documents (and copies thereof) containing or
otherwise relating to any of the Confidential Information (including, without
limitation, all acquisition prospects, lists and contact information) which he
may then possess or have under his control. Executive acknowledges that all such
memoranda, notes, plans, records, reports and other documents are and at all
times will be and remain the property of the Company.

                  (d) Executive will fully comply with any agreement reasonably
required by any of the Company's affiliates, business partners, suppliers or
contractors with respect to the protection of the confidential and proprietary
information of such entities.

         8. NONCOMPETITION AND NONSOLICITATION. Executive acknowledges that in
the course of his employment with the Company he will become familiar with the
Confidential Information concerning the Company and such Subsidiaries and that
his services will be of special, unique and extraordinary value to the Company.
Executive agrees that the Company has a protectable interest in the Confidential
Information acquired by Executive during the course of his employment with the
Company. Therefore, Executive agrees that:

                  (a) NONCOMPETITION. So long as Executive is employed or
affiliated with the Company or any Subsidiary and for an additional (i) two
years thereafter, in the event the Employment Period is terminated as a result
of Executive's resignation or is terminated with Cause or (ii) one year
thereafter, in the event the Employment Period is terminated without Cause (the
"NONCOMPETE PERIOD"), he shall not, anywhere in the United States, directly or
indirectly own, manage, control, participate in, consult with, render services
for, or in any manner engage in the Business or any other business engaged in by
the Company at the time of Separation; provided that in the event of a
termination without Cause, the Board may extend the Noncompete Period for an
additional one-year term by giving notice to Executive ninety (90) days prior to
the end of the then-existing Noncompete Period.

                  (b) NONSOLICITATION. During the Noncompete Period, Executive
shall not directly or indirectly through another entity (i) induce or attempt to
induce any employee of the Company or any of its Subsidiaries to leave the
employ of the Company or such Subsidiary, or in any way interfere with the
relationship between the Company or any of its Subsidiaries and any employee
thereof, (ii) hire any person who was an employee of the Company or any of its
Subsidiaries within 180 days prior to the time such employee was hired by the
Executive, (iii)



                                      8

<PAGE>


induce or attempt to induce any owner of a site location, customer, supplier,
licensee or other business relation of the Company or any of its Subsidiaries to
cease doing business with the Company or such Subsidiary or in any way interfere
with the relationship between any such customer, supplier, licensee or business
relation and the Company or any of its Subsidiaries or (iv) directly or
indirectly acquire or attempt to acquire an interest in any business relating to
the business of the Company or any of its Subsidiaries and with which the
Company or any of its Subsidiaries has entertained discussions or has requested
and received information relating to the acquisition of such business by the
Company or any of its Subsidiaries in the two-year period immediately preceding
a Separation.

                  (c) ENFORCEMENT. If, at the time of enforcement of Section 7
or 8 of this Agreement, a court holds that the restrictions stated herein are
unreasonable under circumstances then existing, the parties hereto agree that
the maximum duration, scope or geographical area reasonable under such
circumstances shall be substituted for the stated period, scope or area and that
the court shall be allowed to revise the restrictions contained herein to cover
the maximum duration, scope and area permitted by law. Because Executive's
services are unique and because Executive has access to Confidential
Information, the parties hereto agree that money damages would be an inadequate
remedy for any breach of this Agreement. Therefore, in the event of a breach or
threatened breach of Section 7 or Section 8 of this Agreement, the Company or
any of its successors or assigns shall, in addition to other rights and remedies
existing in its favor, be entitled to specific performance and/or injunctive or
other relief in order to enforce, or prevent any violations of, the provisions
of Section 7 or Section 8 from any court of competent jurisdiction.

                  (d) ADDITIONAL ACKNOWLEDGMENTS. Executive acknowledges that
the provisions of this Section are in consideration of: (i) employment with the
Company and (ii) additional good and valuable consideration as set forth in this
Agreement. Executive expressly agrees and acknowledges that the restrictions
contained in Sections 7 and 8 do not preclude Executive from earning a
livelihood, nor does it unreasonably impose limitations on Executive's ability
to earn a living. In addition, Executive agrees and acknowledges that the
potential harm to the Company of its non-enforcement outweighs any harm to the
Executive of its enforcement by injunction or otherwise. Executive acknowledges
that he has carefully read this Agreement and has given careful consideration to
the restraints imposed upon the Executive by this Agreement, and is in full
accord as to their necessity for the reasonable and proper protection of the
Confidential Information. Executive expressly acknowledges and agrees that each
and every restraint imposed by this Agreement is reasonable with respect to
subject matter, time period and geographical area.

                               GENERAL PROVISIONS

         9.       DEFINITIONS.

         "AFFILIATE" or "AFFILIATES" of an Investor means any direct or indirect
general or limited partner of such Investor, or any employee or owner thereof,
or any other person, entity or investment fund controlling, controlled by or
under common control with such Investor.



                                    9

<PAGE>


         "CAUSE" means (i) the commission of a felony or a crime involving moral
turpitude or the commission of any other act or omission involving dishonesty or
fraud with respect to the Company or any of its Subsidiaries or any of their
customers or suppliers, (ii) conduct tending to bring the Company or any of its
Subsidiaries into substantial public disgrace or disrepute, (iii) substantial
and repeated failure to perform duties of the office held by Executive as
reasonably directed by the Board, (iv) gross negligence or willful misconduct
with respect to the Company or any of its Subsidiaries or (v) any breach of
Section 7 or 8 of this Agreement.

         "EXECUTIVE'S FAMILY GROUP" means Executive's spouse and descendants
(whether natural or adopted), any trust solely for the benefit of Executive
and/or Executive's spouse and/or descendants and any retirement plan for the
Executive.

         "EXECUTIVE STOCK" will continue to be Executive Stock in the hands of
any holder other than Executive (except for the Company and the Investors and
except for transferees in a Public Sale), and except as otherwise provided
herein, each such other holder of Executive Stock will succeed to all rights and
obligations attributable to Executive as a holder of Executive Stock hereunder.
Executive Stock will also include shares of the Company's capital stock issued
with respect to Executive Stock by way of a stock split, stock dividend or other
recapitalization.

         "FAIR MARKET VALUE" of each share of Executive Stock means the average

exchanges on which such Common Stock may at the time be listed, or, if there
have been no sales on any such exchange on any day, the average of the highest
bid and lowest asked prices on all such exchanges at the end of such day, or, if
on any day such Common Stock is not so listed, the average of the representative
bid and asked prices quoted in the NASDAQ System as of 4:00 P.M., New York time,
or, if on any day such Common Stock is not quoted in the NASDAQ System, of the
average of the highest bid and lowest asked prices on such day in the domestic

Incorporated, or any similar successor organization, in each such case averaged
over a period of 21 days consisting of the day as of which the Fair Market Value
is being determined and the 20 consecutive business days prior to such day. If
at any time such Common Stock is not listed on any securities exchange or quoted
in the NASDAQ System or the over-the-counter market, the Fair Market Value will
be the fair value of such Common Stock determined in good faith by the Board
(the "BOARD CALCULATION"). If the Executive reasonably disagrees with the Board
Calculation, the Executive may, within 30 days after receipt of the Board
Calculation, deliver a notice (an "OBJECTION NOTICE") to the Company setting
forth the Executive's calculation of Fair Market Value. The Board and the
Executive will negotiate in good faith to agree on such Fair Market Value, but
if such agreement is not reached within 30 days after the Company has received
the Objection Notice, Fair Market Value shall be determined by an appraiser
jointly selected by the Board and the Executive, which appraiser shall submit to
the Board and the Executive a report within 30 days of its engagement setting
forth such determination. If the parties are unable to agree on an appraiser
within 45 days after the Company has received the Objection Notice, within seven
days, each party shall submit the names of four nationally recognized investment
banking firms, and each party shall be entitled to strike two names from the
other party's list of firms, and the appraiser shall be selected by lot from the
remaining four investment banking firms. The expenses of such appraiser shall be



                                       10

<PAGE>


borne by the Executive unless the appraiser's valuation is not less than 10%
greater than the amount determined by the Board, in which case, the costs of the
appraiser shall be borne by the Company. The determination of such appraiser
shall be final and binding upon all parties. If the Repurchase Option is
exercised within 90 days after a Separation, then Fair Market Value shall be
determined as of the date of such Separation; thereafter, Fair Market Value
shall be determined as of the date the Repurchase Option is exercised.

purchased hereunder, $___ (as proportionately adjusted for all subsequent stock

Agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or any other jurisdiction, but this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

                  (d) INTENDED THIRD-PARTY BENEFICIARIES. The Investors are

order to enforce or prevent any violations of the provisions of this Agreement.

                  (j) AMENDMENT AND WAIVER. The provisions of this Agreement may
be amended and waived only with the written consent of the Company and the
Executive.

                  (k) BUSINESS DAYS. If any time period for giving notice or

in the state in which the Company's chief executive office is located, the time
period shall be automatically extended to the business day immediately following

                  (l) TERMINATION. This Agreement (except for the provisions of

VIA OVERNIGHT COURIER

AppNet Systems, Inc.
6707 Democracy Boulevard, Suite 1000
Bethesda, Maryland  20817

Attention:     Mr. Jack Pearlstein

         RE:   REPAYMENT OF LOANS AND PREFERRED STOCK

Ladies and Gentlemen:

         Reference is hereby made to each of (a) that certain Revolving Credit
Agreement, dated as of January 8, 1999 (as amended and in effect from time to
time, the "Unguaranteed Credit Agreement"), by and among AppNet Systems, Inc.
(the "Borrower"), BankBoston, N.A. and the other lending institutions set forth
on SCHEDULE 1 thereto (collectively, the "Banks"), BankBoston, N.A. as agent for
itself and the Banks (in such capacity, the "Agent") and Antares Capital
Corporation as co-agent for itself and the Banks; and (b) that certain Revolving
Credit Agreement, dated as of January 8, 1999 (as amended and in effect from
time to time, the "Guaranteed Credit Agreement"), by and among AppNet Systems,
Inc. (the "Borrower"), BankBoston, N.A. and the other lending institutions set
forth on SCHEDULE 1 thereto (collectively, the "Guaranteed Banks"), BankBoston,
N.A. as agent for itself and the Guaranteed Banks (in such capacity, the
"Guaranteed Agent") and Antares Capital Corporation as co-agent for itself and
the Guaranteed Banks. Capitalized terms used herein and which are not otherwise
defined shall have the respective meanings ascribed thereto in the Unguaranteed
Credit Agreement.

         The Borrower has advised the Agent, the Guaranteed Agent, the Banks and
the Guaranteed Banks that, in connection with the Borrower's IPO, the Borrower
is contemplating (a) repaying all outstanding Obligations (as such term is
defined in the Guaranteed Credit Agreement) under the Guaranteed Credit
Agreement and terminating the Commitment (as such term is defined in the
Guaranteed Credit Agreement) of each of the Guaranteed Banks under the
Guaranteed Credit Agreement in their entirety, but retaining in full force and
effect the Commitment under the Unguaranteed Credit Agreement, and retaining
such Commitment in effect without the limitations to borrowings based on the
Guaranteed Credit Agreement set forth in ss.2.1 and ss.3.2 of the Unguaranteed
Credit Agreement (such transaction being hereinafter referred to as the
"Termination of Guaranteed Facility"); (b) redeeming all or a portion of the
Borrower's Class A and Class B Preferred Stock (the "Stock Redemption") and

<PAGE>

AppNet Systems, Inc.
May 28, 1999
Page -2-

converting or exchanging any Class A and Class B Preferred Stock that is not
redeemed for the Borrower's common stock; and (c) prepaying all or a portion of
the Seller Subordinated Debt (the "Subordinated Debt Repayment"). The occurrence
of the Termination of Guaranteed Facility, the Stock Redemption and/or the
Subordinated Debt Repayment, or any one of or any combination of such events
shall hereinafter be referred to as the "IPO Transactions".

         As you are aware, (a) ss.2.1 of the Unguaranteed Credit Agreement does
not permit the sum of the outstanding Revolving Credit Loans PLUS the Maximum
Drawing Amount and all Unpaid Reimbursement Obligations to exceed the Guaranteed
Credit Agreement Outstandings; (b) ss.2.3 of the Unguaranteed Credit Agreement
does not permit the Total Commitment under the Unguaranteed Credit Agreement to
exceed the amount of the Total Commitment under the Guaranteed Credit Agreement;
(c) ss.3.2 of the Unguaranteed Credit Agreement requires that, to the extent the
sum of the outstanding amount of the Revolving Credit Loans, the Maximum Drawing
Amount and all Unpaid Reimbursement Obligations exceeds the Guaranteed Credit
Agreement Outstandings, then the Borrower will repay such excess; (d) ss.9.4 of
the Unguaranteed Credit Agreement does not permit the Borrower to effect the
Stock Redemption (except with respect to the Class A Preferred Stock); (e)
ss.9.18 of the Unguaranteed Credit Agreement does not permit the Borrower to
prepay, redeem or repurchase any of the Seller Subordinated Debt; (f) Section
12.6 of the Unguaranteed Credit Agreement requires, as a condition to borrowing
thereunder, that the Borrower demonstrate that the Total Commitment in the
Guaranteed Credit Agreement is not less than the Total Commitment in the
Unguaranteed Credit Agreement and that the sum of the outstanding Revolving
Credit Loans plus the Maximum Drawing Amount and all Unpaid Reimbursement
Obligations under the Unguaranteed Credit Agreement does not exceed the
Guaranteed Credit Agreement Outstandings; (g) ss.2.3 of the Guaranteed Credit
Agreement does not permit the Borrower to reduce the Total Commitment under the
Guaranteed Credit Agreement to an amount which is less than the Total Commitment
under the Unguaranteed Credit Agreement; (h) ss.9.4 of the Guaranteed Credit
Agreement does not permit the Borrower to effect the Stock Redemption (except
with respect to the Class A Preferred Stock); and (i) ss.9.18 of the Guaranteed
Credit Agreement does not permit the Borrower to prepay, redeem or repurchase
any of the Seller Subordinated Debt. As such, the Borrower has asked the Agent,
the Guaranteed Agent and the Majority Banks (as such term is defined in each of
the Unguaranteed Credit Agreement and the Guaranteed Credit Agreement) to
consent to the IPO Transactions. The Agent, the Guaranteed Agent and the
Majority Banks hereby consents to the IPO Transactions on the conditions that:

         (a) the net cash proceeds received by the Borrower in connection with
the IPO are an amount which is not less than the aggregate amount necessary to
repay all outstanding Revolving Credit Loans under each of the Guaranteed Credit
Agreement


<PAGE>

AppNet Systems, Inc.
May 28, 1999
Page -3-

and the Unguaranteed Credit Agreement, together with any and all
interest and fees accrued thereunder;

         (b) the Borrower shall (i) use the net cash proceeds received in
connection with the IPO to repay all outstanding Revolving Credit Loans under
each of the Guaranteed Credit Agreement and the Unguaranteed Credit Agreement,
and any and all interest and fees accrued to date thereunder; (ii) permanently
reduce the Total Commitment under the Guaranteed Credit Agreement to zero; and
(iii) permanently reduce the Total Commitment under the Unguaranteed Credit
Agreement to $20,000,000;

         (c) the Borrower shall have demonstrated to the satisfaction of the
Agent that the Borrower has not less than $10,000,000 of cash and "Cash
Equivalents" (defined as all investment in direct obligations of the United
States of America or any agency thereof with a maturity of not more than one
year, certificates of deposit with a maturity of less than ninety (90) days
issued by BKB or any other commercial bank organized under the laws of the
United States of America or any state thereof if such other bank has a
short-term debt rating in the highest rating category of either Moody's
Investors Services, Inc. or Standard & Poors Corporation, and commercial paper
with a maturity of less than ninety (90) days that is rated in the highest
rating category of either Moody's Investors Services, Inc. or Standard & Poors
Corporation) on its balance sheet and located at the Agent's Head Office, and,
in addition, the Borrower agreeing at all times from and after the date hereof
to maintain not less than $10,000,000 of cash and Cash Equivalents on its
balance sheet and located at the Agent's Head Office;

         (d) the Borrower shall not make any Subordinated Debt Repayments until
such time as all of the Class A and Class B Preferred Stock has been redeemed or
otherwise converted or exchanged into the Borrower's common stock;

         (e) until such time as the amount of cash and Cash Equivalents on the
balance sheet of the Borrower is equal to or greater than $15,000,000, the
Borrower shall not be permitted to use more than sixty percent (60%) of the
"Remaining IPO Proceeds" (defined as the net cash proceeds received by the
Borrower in connection with the IPO after giving effect to all required
repayments required to be made to the Agent and the Banks pursuant to paragraph
(b) above and after giving effect to the Borrower retaining any cash required to
cause the Borrower to comply with paragraph (c) above) to effect any Stock
Redemption or Subordinated Debt Repayment, and, at such time as the cash and
Cash Equivalents on the Borrower's balance sheet equal or exceed $15,000,000 the
Borrower shall be permitted to use 100% of any remaining Remaining IPO Proceeds
to effect the Stock Redemption and the Subordinated Debt Repayment so long as at
all times (both before and after giving effect to any Stock Redemption and
Subordinated


<PAGE>

AppNet Systems, Inc.
May 28, 1999
Page -4-

Debt Repayment) the amount of the cash and Cash Equivalents on the Borrower's
balance sheet is not less than $15,000,000;

         (f) the Borrower will not use any Revolving Credit Loans under the
Unguaranteed Credit Agreement to fund any Stock Redemptions or to make any
Subordinated Debt Repayments, and such Stock Redemptions and Subordinated Debt
Repayments shall be made only with the Remaining IPO Proceeds;

         (g) the Borrower agrees to cause Claymore Partners to deliver to the
Agent the results of its commercial finance examination by not later than
September 30, 1999, and the result shall be satisfactory to Claymore, the Agent
and the Majority Banks in their sole discretion (including the compliance by the
Borrower with all of the financial management requirements that Claymore or the
Agent may require);

         (h) notwithstanding anything to the contrary contained in the
Unguaranteed Credit Agreement (including without limitation the covenant
contained in ss.10.1 thereof), the Borrower's Leverage Ratio at all times from
and after the date of the consummation of the IPO Transactions shall not exceed
2.50:1.00;

         (i) all Stock Redemptions and Subordinated Debt Payments shall have
been consummated by not later than thirty (30) days after the consummation of
the IPO; and

         (j) no Default or Event of Default (as such terms are defined in each
of the Guaranteed Credit Agreement and the Unguaranteed Credit Agreement) has
occurred and is continuing or would exist as a result of the IPO Transactions.

         Subject to such conditions, the Majority Banks, the Guaranteed Agent
and the Agent hereby consent to the IPO Transactions pursuant to ss.26 of each
of the Guaranteed Credit Agreement and the Unguaranteed Credit Agreement. This
consent shall not be construed, however, as a waiver of any other provisions of
the Loan Documents (as such term is defined in each of the Guaranteed Credit
Agreement and the Unguaranteed Credit Agreement) or to permit the Borrower or
any Subsidiary to take any other action which is prohibited by the terms of the
Unguaranteed Credit Agreement, the Guaranteed Credit Agreement and the other
Loan Documents (as such term is defined in each of the Guaranteed Credit
Agreement and the Unguaranteed Credit Agreement).

         The Borrower hereby acknowledges and agrees that (a) the execution and
delivery by the Borrower of this consent shall constitute the election by the
Borrower upon the consummation of the IPO Transactions to permanently reduce the
Total Commitment under the Unguaranteed Credit Agreement to $20,000,000 and the
notice required by ss.2.3 of the Unguaranteed Credit Agreement; (b) the Borrower
agrees that upon the consummation of the IPO Transactions it shall at all times
thereafter maintain

cash and Cash Equivalents of not less than $10,000,000 on its balance sheet, and
(c) the Borrower agrees upon the consummation of the IPO Transactions to be
bound by the covenant contained in subparagraphs (b), (g) and (h) and by all the
requirements set forth in paragraphs (a) - (j) above, and any failure to so
comply with any covenant contained therein shall constitute an Event of Default
under the Unguaranteed Credit Agreement.

         Except as expressly stated herein, neither the execution of this
consent nor the failure of the Banks or the Guaranteed Banks to exercise any
right or remedy constitutes a waiver of any Default or Event of Default (as such
terms are defined in each of the Guaranteed Credit Agreement and the
Unguaranteed Credit Agreement) or of such right or remedy or any other right or
remedy under the Guaranteed Credit Agreement and the Unguaranteed Credit
Agreement.

                                           Sincerely,
