                              APPNET SYSTEMS, INC.

    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 foreseeable 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

expertise; 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
principal executive office is located at 6707 Democracy Boulevard, Suite 1000,

                                  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 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
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. Some of our competitors, IBM, USWeb and EDS,
currently provide all of the services that we provide.

    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.

                                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.

                                    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:

    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.

                    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.

    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

                                       18

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:

    In addition, an interest charge of approximately $0.9 million will be
recorded related to the beneficial conversion rights of convertible notes, which
is not reflected in the pro forma consolidated statement of operations.

    (e) This adjustment was made to eliminate costs of investment advisors and
other professionals incurred by the companies we acquired in 1998 and 1999 which
were directly attributable to the sale of those companies to AppNet.

    (f) This adjustment was made to record the estimated tax benefit for the
full year of 1998 and the estimated tax provision for the three months ended
March 31, 1999 and to reflect the tax impact of the previous pro forma
adjustments, net of an applicable valuation allowance.

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.

CORPORATION, IN CONJUNCTION WITH THEIR RESPECTIVE CONSOLIDATED FINANCIAL
STATEMENTS AND THE RELATED NOTES, "PRO FORMA CONSOLIDATED FINANCIAL DATA" AND
"SELECTED FINANCIAL DATA" INCLUDED ELSEWHERE IN THIS PROSPECTUS.

OVERVIEW

    AppNet provides Internet and electronic commerce professional services and
solutions to medium-sized and large businesses. We develop end-to-end electronic
commerce solutions that improve communication and commerce between businesses
and consumers as well as among businesses and their trading partners. Through
strategic acquisitions and internal growth, we have built a company with the
ability to design, develop, implement and manage end-to-end Internet and
electronic commerce solutions.

    AppNet's financial statements for the period from inception, November 6,
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
<PAGE>
    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.

solution. We were formed in 1997 as a Delaware corporation.

    Our professional services include:

      electronic commerce systems, which are systems that automate the receipt,

    - 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.

    None of these services is more critical to our business operations and
revenues than the other services.

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

                                       38
<PAGE>
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. 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

                                       39
<PAGE>
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 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

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.

    - 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

                                       41
<PAGE>
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:

    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 Systems' and
our collective analysis of this data, we were able to make real-time adjustments
to Multex Systems' ad campaign. Our solution is designed to increase overall
membership for Multex Systems, 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

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. Some of our competitors,
IBM, USWeb and EDS, currently provide all of the services that we provide.

    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.

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.

    Our Board of Directors is currently composed of five directors. Each of the
current members of the Board of Directors has been elected in accordance with
the terms of the Stockholders' Agreement, dated as of June 29, 1998, by and
among AppNet and substantially all of our current stockholders, which will
terminate upon consummation of this offering. We intend to expand the Board to
include two outside directors after 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 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
and a Compensation Committee, each composed of a majority of independent
directors. The Audit Committee will recommend the annual appointment of our
auditors with whom the Audit Committee will review the scope of audit and
non-audit assignments and related fees, accounting principles we use in
financial reporting, internal auditing procedures and the adequacy of our
internal control procedures. The Compensation Committee will make
recommendations to the Board of Directors regarding compensation for our
executive officers. GTCR will be entitled to appoint its designee to the
Compensation Committee.

COMPENSATION OF DIRECTORS

    Directors who are also employees of AppNet receive no additional
compensation for their services as directors. Directors who are not AppNet
employees will not receive a fee for attendance in person at meetings of the
Board of Directors or committees of the Board of Directors, but they will be
reimbursed for travel expenses and other out-of-pocket costs incurred in
connection with the attendance of meetings. Non-employee directors will receive
options to purchase our common stock in connection with their appointment to the
Board of Directors. Non-employee directors will also receive automatic grants of
options to purchase our common stock each year that they are re-elected to the
Board of Directors.

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.

EXECUTIVE COMPENSATION

    The following table sets forth a summary of compensation for services
rendered in all capacities to us by the Chief Executive Officer and President

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

                                       61
<PAGE>
common stock for issuance in connection with options granted under the Century
Incentive Stock Option Plan.

    As of May 26, 1999, options to purchase a total of 45,627 shares of our
common stock were outstanding under the Century Incentive Stock Option Plan and
remain unexercised, 658,499 shares of our common stock have been issued upon the
exercise of options granted under the Century Incentive Stock Option Plan and
options to purchase 45,627 shares of our common stock granted under the Century
Incentive Stock Option Plan are currently exercisable.

    The Century Incentive Stock Option Plan is administered by Century
Computing's board of directors unless the board of directors delegates the power
and authorities related to the administration of the Century Incentive Stock
Option Plan to a board-appointed committee. The board of directors or a
board-appointed committee is authorized to construe, interpret and implement the
provisions of the Century Incentive Stock Option 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 Century Incentive Stock Option Plan has no termination date, however, no
incentive stock options may be granted under the Century Incentive Stock Option
Plan after the expiration of the ten-year period beginning on the date the
Century Incentive Stock Option Plan was adopted. The board of directors may at
any time and from time to time amend or terminate the Century Incentive Stock
Option Plan; provided, however, that, to the extent necessary under applicable
law, no such change will be effective without the requisite approval of the
stockholders. AppNet does not intend to make any new grants under the Century
Incentive Stock Option Plan.

    INTERNET OUTFITTERS, INC. 1996 INCENTIVE STOCK OPTION PLAN

    In connection with our acquisition of Internet Outfitters, Inc., we assumed
its 1996 Incentive Stock Option Plan and related award agreements with each
grantee. Each outstanding option to purchase the common stock of Internet
Outfitters was converted into an incentive stock option to purchase our common
stock based on a conversion ratio. Originally, we reserved a total of 22,300
shares of our common stock for issuance in connection with options granted under
the Internet Outfitters Incentive Stock Option Plan.

    As of May 26, 1999, options to purchase a total of 22,300 shares of our
common stock were outstanding under the Internet Outfitters Incentive Stock
Option Plan and remain unexercised, no options have been exercised and options
to purchase 1,916 shares of our common stock granted under the Internet
Outfitters Incentive Stock Option Plan are currently exercisable.

    The Internet Outfitters Incentive Stock Option Plan is administered by the
Internet Outfitters board of directors unless the board of directors delegates
the power and authorities related to the administration of the Internet
Outfitters Incentive Stock Option Plan to a board-appointed committee. The board
of directors or a board-appointed committee is authorized to construe, interpret
and implement the provisions of the Internet Outfitters Incentive Stock Option
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 Internet Outfitters Incentive Stock Option Plan will terminate upon the
expiration of the ten-year period beginning on the date the Internet Outfitters
Incentive Stock Option Plan was adopted. The board of directors may at any time
and from time to time amend or terminate the Internet Outfitters Incentive Stock
Option Plan; provided, however, that, to the extent necessary under applicable
law, no such change will be effective without the requisite approval of the
stockholders. AppNet does not intend to make any new grants under the Internet
Outfitters Incentive Stock Option Plan.

                     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.

OTHER RELATIONSHIPS AND TRANSACTIONS

    Foxhall Capital, LLC, an entity controlled by Jack Pearlstein, and AppNet
signed an agreement dated January 18, 1998, under which Foxhall Capital, LLC

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 selling 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 selling concession and discount to dealers may be changed by
the representatives. As used in this section,

    - Underwriters are securities broker/dealers that are parties to the
      underwriting agreement and will have a contractual commitment to purchase
      shares of our common stock from us, and the representatives are the five
      firms acting on behalf of the underwriters.

    - Selling group members are securities broker/dealers to whom the
      underwriters may sell shares of common stock at the public offering price
      less the selling concession above, but who do not have a contractual
      commitment to purchase shares from us.

    - Broker/dealers are firms registered under applicable securities laws to
      sell securities to the public.

    - The syndicate consists of the underwriters and the selling group members.


    The following table summarizes the compensation and estimated expenses that
we will pay. The compensation we will pay to the underwriters will consist
solely of the underwriting discount, which is equal to the public offering price
per share of common stock less the amount the underwriters pay to us per share
of common stock. The underwriters have not received and will not receive from us
any other item of compensation or expense in connection with this offering
considered by the National Association of Securities Dealers, Inc. to be
underwriting compensation under its rules of fair practice. The underwriting fee
will be determined based on our negotiations with the underwriters at the time
the initial public offering price for our common stock is determined. We do not
expect the underwriting

discount per share of common stock to exceed 7% of the initial public offering
price per share of common stock.

    The principal components of the offering expenses payable by us will include
the fees and expenses of our accountants and attorneys, the fees of our
registrar and transfer agent, the cost of printing this prospectus, The Nasdaq
Stock Market listing fees and filing fees paid to the Securities and Exchange
Commission and the National Association of Securities Dealers, Inc.

    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.

    At our request, the underwriters intend to sell, at the initial public
offering price, approximately 5% of the shares of our common stock offered in
this offering to those of our employees, clients and vendors 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 in fact purchase these shares. Any
of these 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.

    The shares of our common stock have been approved for quotation 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;

                                       82
<PAGE>
    - 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; and

    - the general condition of the securities markets at the time of this
      offering.

    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. The representatives track such purchases
through the initial public offering tracking system operated by the Depository
Trust Company. The representatives may, at their discretion, reclaim a selling
concession from any syndicate member that appears to have permitted its
customers to purchase shares in the initial public offering and then promptly
resell all or a portion of such shares to such syndicate member. However, the
underwriters do not have any agreements with any potential purchasers of shares
of common stock in this offering that would restrict their transfer of such
shares following this offering.

    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

                                       83
<PAGE>
    - 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.

                    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.

                   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:

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.

RECLASSIFICATIONS

    Certain amounts have been reclassified to conform with the current
presentation.

INTERIM FINANCIAL INFORMATION

    The financial information as of March 31, 1999 and for the three months
ended March 31, 1998 and 1999 is unaudited but includes all adjustments,
consisting only of normal recurring adjustments, that AppNet's management
considers necessary for a fair presentation of AppNet's operating results and
cash flows for such periods. Results for the three month period ended March 31,
1999 are not necessarily indicative of results to be expected for the full
fiscal year of 1999 or for any future period.

3.  ACQUISITIONS:

1998 ACQUISITIONS

    From March 1998 through December 1998, the Company acquired businesses in
the Internet and electronic commerce professional services industry.
Collectively, these entities are referred to as the "1998 Acquired Businesses."
The accounts of the Acquired Businesses are included in the accompanying
consolidated financial statements from the date of their respective
acquisitions. These acquisitions are described as follows:

    On March 12, 1998, the Company acquired the assets of Arbor Intelligent
Systems, Inc. ("Arbor"), for an aggregate purchase price of approximately
$3,100,000, including transaction costs, of which $1,100,000 was paid in the
form of the Company's Series A-1 Convertible Preferred Stock (266,796 shares
valued at $4 per share), and $2,000,000 was paid in cash. Arbor is engaged in
the business of providing object-oriented development services.

    On April 30, 1998, the Company acquired the assets of LOGEX International,
L.L.C. ("LOGEX"), in exchange for approximately $300,000 in cash and a five-year
convertible note in the principal amount of $300,000 (Note 9). The former
shareholders of LOGEX are entitled to a contingent consideration payment in the
event that certain performance criteria are achieved by LOGEX during the year
ending April 30, 1999. LOGEX provides electronic commerce systems integration
services and is located in Falls Church, Virginia.

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.

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

                      DECEMBER 31, 1998 AND MARCH 31, 1999

consolidated financial statements. The Company has also issued warrants to
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

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                      DECEMBER 31, 1998 AND MARCH 31, 1999

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.

</TABLE>

    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.

                      DECEMBER 31, 1998 AND MARCH 31, 1999

    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.

16. COMMITMENTS AND CONTINGENCIES:

</TABLE>

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 2.85-for-one 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:

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

*   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.

RECLASSIFICATIONS

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

    As a condition of the sale of the Company to AppNet, all of the Company's
outstanding debt was repaid prior to August 24, 1998. In contemplation of the
repayment, AppNet advanced funds to the Company to repay the debt. The funds
received by AppNet have been included in additional paid-in capital in the
accompanying financial statements.

11. STOCKHOLDERS' EQUITY:

STOCK SPLIT

    During 1997, the Company declared a stock split of six-to-one for each
holder of common stock. All share information included in the accompanying
financial statements has been restated to retroactively reflect the stock split.

STOCK OPTION PLAN

    During 1995, the Company established a stock option plan (the "Plan") to
encourage ownership by selected employees of the Company and provide an
additional incentive to these employees to promote the success of the Company.
Under the Plan, options to purchase the Company's common stock may be granted at
the discretion of the Board of Directors. The maximum number of shares that may
be granted is 1,500,000. The Plan may be terminated at any time at the
discretion of the Board of Directors. According to the Plan, the options will be
granted at a price equal to 100 percent of the fair market value of the common
stock as determined by the Board of Directors. All options will expire ten years
after date of grant. During the years ended December 31, 1996 and 1997 and the
for the period from January 1, 1998 to August 24, 1998, the Company granted
108,000, 170,000 and 20,000 options, respectively, at an option price of $1.00,
all of which vest over four years. During the years ended December 31, 1996,
1997 and for the period from January 1, 1998 to August 24, 1998, 372,000, 90,000
and 54,000 options were cancelled due to termination of employment,
respectively. As of December 31,

                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:

14. RELATED-PARTY TRANSACTIONS:

    The Company purchased consulting services from an affiliate for
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.

To Arbor Intelligent Systems, Inc.:

    We have audited the accompanying balance sheets of Arbor Intelligent

    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

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

                         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.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                      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.

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 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.

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:

                         NOTES TO FINANCIAL STATEMENTS

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

1.  BUSINESS DESCRIPTION:

    New Media Publishing, Inc. ("NMP" or the "Company") was incorporated in
1995, under the laws of the state of Virginia. NMP is a provider of
comprehensive interactive community-building services for commercial and
not-for-profit entities. The Company is headquartered in Falls Church, Virginia.

    On October 2, 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 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

                                      F-60

                           NEW MEDIA PUBLISHING, INC.

                   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

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.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

             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
amounts.

9.  NOTE PAYABLE:

    During 1995, the Company purchased a portion of a stockholder's shares for
$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
401(k) plan.

11. STOCKHOLDER AGREEMENTS:

    During the year ended December 31, 1996, the Company established Class B

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

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.

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.

To The Kodiak Group, Inc.:

    We have audited the accompanying balance sheets of The Kodiak Group, Inc. (a
Massachusetts corporation), as of December 31, 1997, and December 13, 1998, and
the related statements of operations, stockholders' equity, and cash flows for
the year ended December 31, 1997, and for the period from January 1, 1998 to
December 13, 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 Kodiak Group, Inc. as of
December 31, 1997, and December 13, 1998, and the results of its operations and
its cash flows for the year ended December 31, 1997, and for the period from

                         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.

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

plan is for the benefit of all employees who have reached one year of service.
Participants may contribute up to 12 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. In
1997 and 1998, the discretionary rate was 3 percent of gross salary. Company
contributions vest at a rate of 25 percent a year, beginning in the employee's
first eligible year. Company contributions totaled $39,000, and $51,000 for the
year ended December 31, 1997, and for the period from January 1, 1998 to
December 13, 1998, respectively.

To i33 Communications Corporation:

    We have audited the accompanying balance sheets of i33 Communications
Corporation (a Delaware corporation), as of December 31, 1996, 1997, and 1998,
and the related statements of operations, stockholders' equity (deficit), and
cash flows for the years 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 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 i33 Communications
Corporation as of December 31, 1996, 1997, and 1998, and the results of its
operations and its cash flows for the years then ended in conformity with

                         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.

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 financial statements referred to above present fairly,
in all material respects, the financial position of Salzinger & Company as of
December 31, 1998, and the results of its operations and its cash flows for the
year then ended in conformity with generally accepted accounting principles.

                         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

                               DECEMBER 31, 1998

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:

</TABLE>

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

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 or state income taxes has been included in the
accompanying financial statements.

                         NOTES TO FINANCIAL STATEMENTS

                               DECEMBER 31, 1998

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

cost-plus-fixed-fee contracts are recognized on the basis of direct costs plus
indirect costs incurred plus a fixed profit percentage.

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.

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

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.

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 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. 5 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 June 15, 1999.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

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
statements of Software Services Corporation included in this registration
statement and have issued our reports thereon dated March 29, 1999 (except with
respect to the matter discussed in Note 18, as to which the date is June 15,
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
accompanying Schedule II -- Valuation and Qualifying Accounts for AppNet
Systems, Inc. and Software Services Corporation are the responsibility of the
Company's management and are presented for purposes of complying with the
Securities and Exchange Commission's rules and are not part of the basic
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.

                      RESTATED CERTIFICATE OF INCORPORATION
                                       OF
                              APPNET SYSTEMS, INC.


         AppNet Systems, Inc., a corporation existing under the laws of the
State of Delaware (the "Corporation"), hereby certifies as follows:

         1. The name of the Corporation is AppNet Systems, Inc. AppNet Systems,
Inc. was originally incorporated under the name Internet Applications, Inc., and
the original Certificate of Incorporation was filed with the Secretary of State
of the State of Delaware on November 6, 1997.

         2. This Restated Certificate of Incorporation restates and integrates
and further amends the provisions of the Certificate of Incorporation of the
Corporation and has been adopted pursuant to the provisions of Sections 242 and
245 of the General Corporation Law of the State of Delaware.

         3. The text of the Restated Certificate of Incorporation as heretofore
amended or supplemented is hereby restated and further amended to read in its
entirety as follows:

         FIRST:  The name of the Corporation is AppNet Systems, Inc.

         SECOND: The address of the Corporation's registered office in the State
of Delaware is Corporation Service Company, 1013 Centre Road, in the City of
Wilmington, County of New Castle, Delaware 19805. The name of its registered
agent at such address is Corporation Service Company.

         THIRD: The purpose of the Corporation is to engage in any lawful act or
activity for which corporations may be organized under the General Corporation
Law of the State of Delaware (the "DGCL").

         FOURTH: The aggregate number of shares of all classes of capital stock
which the Corporation shall have the authority to issue is 80,000,000 of which
(i) 75,000,000 shall be designated common stock, par value $.0005 per share
("Common Stock"), and (ii) 5,000,000 shall be designated preferred stock, par
value $.01 per share ("Preferred Stock").

         A. Common Stock

                  Except as otherwise provided in this Part A or as otherwise
required by applicable law, all shares of Common Stock shall be identical in all
respects and shall entitle the holders thereof to the same rights and
privileges, subject to the same qualifications, limitations and restrictions.


<PAGE>

                  1. DIVIDENDS. Subject to the preferential rights, if any, of
the Preferred Stock, the holders of shares of Common Stock shall be entitled to
receive, when and if declared by the Board of Directors, out of the assets of
the Corporation which are by law available therefor, dividends payable either in
cash, in property, or in shares of capital stock.

                  2. VOTING RIGHTS. At every annual or special meeting of the
stockholders of the Corporation, every holder of Common Stock shall be entitled
to one vote, in person or by proxy, for each share of Common Stock standing in
his name on the books of the Corporation.

                  3. LIQUIDATION, DISSOLUTION, OR WINDING UP. In the event of
any voluntary or involuntary liquidation, dissolution, or winding up of the
affairs of the Corporation after payment or provision for payment of the debts
and other liabilities of the Corporation and of the preferential amounts, if
any, to which holders of Preferred Stock shall be entitled, the holders of all
outstanding shares of Common Stock shall be entitled to share ratably in the
remaining net assets of the Corporation.

         B. Preferred Stock

                  Shares of the Preferred Stock of the Corporation may be issued
from time to time in one or more classes or series, each of which class or
series shall have such distinctive designation or title as shall be fixed by the
Board of Directors of the Corporation prior to the issuance of any shares
thereof. Each such class or series of Preferred Stock shall have such voting
powers, full or limited or no voting powers and such preferences and relative,
participating, optional or other special rights and such qualifications,
limitations or restrictions thereof, as shall be stated in such resolution or
resolutions providing for the issue of such class or series of Preferred Stock
as may be adopted from time to time by the Board of Directors prior to the
issuance of any shares thereof pursuant to the authority hereby expressly vested
in it, all in accordance with the laws of the State of Delaware.

         C. Class A and Class B Preferred Stock

                           a. CLASS A PREFERRED STOCK. The shares of such class
shall be designated as "Class A Preferred," the shares of such class shall be
with par value of $.01 per share, and the number of shares constituting such
class shall be 96,621.

                           b. CLASS B PREFERRED STOCK. The shares of such class
shall be designated as "Class B Preferred," the shares of such class shall be

                                      -2-

<PAGE>


                  2. DIVIDENDS.

                           a. GENERAL OBLIGATION. When and as declared by the
Corporation's Board of Directors and to the extent permitted under the DGCL, the
Corporation shall pay preferential dividends in cash to the holders of the Class
A and Class B Preferred as provided in this Section 2. Dividends on each share
of the Class A and Class B Preferred (a "SHARE") shall accrue on a daily basis
at the rate of 6% per annum of the sum of the Liquidation Value thereof plus all
accumulated and unpaid dividends thereon from and including the date of issuance
of such Share to and including the first to occur of (i) the date on which the
Liquidation Value of such Share (plus all accrued and unpaid dividends thereon)
is paid to the holder thereof in connection with the liquidation of the
Corporation or the redemption of such Share by the Corporation or (ii) the date
on which such Share is otherwise acquired by the Corporation. Such dividends
shall accrue whether or not they have been declared and whether or not there are
profits, surplus or other funds of the Corporation legally available for the
payment of dividends, and such dividends shall be cumulative such that all
accrued and unpaid dividends shall be fully paid or declared with funds
irrevocably set apart for payment before any dividends, distributions,
redemptions or other payments may be made with respect to any Junior Securities.
The date on which the Corporation initially issues any Share shall be deemed to
be its "date of issuance" regardless of the number of times transfer of such
Share is made on the stock records maintained by or for the Corporation and
regardless of the number of certificates which may be issued to evidence such
Share.

                           b. DIVIDEND REFERENCE DATES. To the extent not paid
on March 31, June 30, September 30 and December 31 of each year, beginning June
30, 1998 for the Class A Preferred and September 30, 1998 for the Class B
Preferred (the "DIVIDEND REFERENCE DATES"), all dividends which have accrued on
each Share outstanding during the three-month period (or other period in the
case of the initial Dividend Reference Date) ending upon each such Dividend
Reference Date shall be accumulated and shall remain accumulated dividends with
respect to such Share until paid to the holder thereof.

                           c. DISTRIBUTION OF PARTIAL DIVIDEND PAYMENTS. Except
as otherwise provided herein, if at any time the Corporation pays less than the
total amount of dividends then accrued with respect to the Class A or Class B
Preferred such payment shall be distributed pro rata among the holders thereof
based upon the aggregate accrued but unpaid dividends on the Shares held by each
such holder.

                  3. LIQUIDATION. Upon any liquidation, dissolution or winding
up of the Corporation (whether voluntary or involuntary), each holder of Class A
or Class B Preferred shall be entitled to be paid, before any distribution or
payment is made upon any Junior Securities, an amount in cash equal to the
aggregate Liquidation Value of all Shares held by such holder (plus all accrued
and unpaid dividends thereon), and the holders of Class A or Class B Preferred
shall not be entitled to any further payment. If upon any such liquidation,
dissolution or winding up of the Corporation the Corporation's assets to be
distributed among the holders of the Class A and Class B Preferred are
insufficient to permit payment to such holders of the aggregate amount which
they are entitled to be paid under this Section 3, then the entire assets

                                      -3-

<PAGE>

available to be distributed to the Corporation's stockholders shall be
distributed pro rata among such holders based upon the aggregate Liquidation
Value (plus all accrued and unpaid dividends) of the Class A and Class B
Preferred held by each such holder. Not less than 60 days prior to the payment
date stated therein, the Corporation shall mail written notice of any such
liquidation, dissolution or winding up to each record holder of Class A or Class
B Preferred, setting forth in reasonable detail the amount of proceeds to be
paid with respect to each Share and each share of Common Stock in connection
with such liquidation, dissolution or winding up.

                  4. PRIORITY OF PREFERRED STOCK. So long as any Class A or
Class B Preferred remains outstanding, without the prior written consent of the
holders of a majority of the outstanding Shares of Class A or Class B Preferred,
the Corporation shall not, nor shall it permit any Subsidiary to, redeem,
purchase or otherwise acquire directly or indirectly any Junior Securities, nor
shall the Corporation directly or indirectly pay or declare any dividend or make
any distribution upon any Junior Securities; provided that the Corporation may
purchase shares of Common Stock pursuant to arrangements approved by the Board
from present or former employees of the Corporation or its Subsidiaries.

                  5. VOTING RIGHTS. Except as otherwise provided herein and as
otherwise required by applicable law, the Class A and Class B Preferred shall
have no voting rights, provided that each holder of Class A or Class B Preferred
shall be entitled to notice of all stockholders meetings at the same time and in
the same manner as notice is given to all stockholders entitled to vote at such
meetings.

         D. Class A Preferred Stock

                  1. REDEMPTIONS.

                           a. OPTIONAL REDEMPTIONS. The Corporation may at any
time and from time to time redeem all or any portion of the Shares of Class A
Preferred then outstanding. Upon any such redemption, the Corporation shall pay
a price per Share equal to the Liquidation Value thereof (plus all accrued and
unpaid dividends thereon). No redemption pursuant to this Section may be made
for less than 1,000 Shares (or such lesser number of Shares then outstanding).

                           b. REDEMPTION AFTER PUBLIC OFFERING. The Corporation
shall, at the request (by written notice given to the Corporation) of the
holders of a majority of the Class A Preferred, apply the net cash proceeds from
any Public Offering remaining after deduction of all discounts, underwriters'
commissions and other reasonable expenses to redeem Shares of Class A Preferred
at a price per Share equal to the Liquidation Value thereof (plus all accrued
and unpaid dividends thereon). Such redemption shall take place on a date fixed
by the Corporation, which date shall be not more than five days after the
Corporation's receipt of such proceeds.

                           c. REDEMPTION PAYMENTS. For each Share which is to be
redeemed hereunder, the Corporation shall be obligated on the Redemption Date to
pay to the holder thereof (upon surrender by such holder at the Corporation's
principal office of the certificate representing such Share) an amount in
immediately available funds equal to the Liquidation

                                      -4-

<PAGE>

Value of such Share (plus all accrued and unpaid dividends thereon). If the
funds of the Corporation legally available for redemption of Shares on any
Redemption Date are insufficient to redeem the total number of Shares to be
redeemed on such date, those funds which are legally available shall be used to
redeem the maximum possible number of Shares pro rata among the holders of the
Shares to be redeemed based upon the aggregate Liquidation Value of such Shares
held by each such holder (plus all accrued and unpaid dividends thereon). At any
time thereafter when additional funds of the Corporation are legally available
for the redemption of Shares, such funds shall immediately be used to redeem the
balance of the Shares which the Corporation has become obligated to redeem on
any Redemption Date but which it has not redeemed.

                           d. NOTICE OF REDEMPTION. Except as otherwise provided
herein, the Corporation shall mail written notice of each redemption of any
Class A Preferred to each record holder thereof not more than 60 nor less than
30 days prior to the date on which such redemption is to be made. In case fewer
than the total number of Shares represented by any certificate are redeemed, a
new certificate representing the number of unredeemed Shares shall be issued to
the holder thereof without cost to such holder within five business days after
surrender of the certificate representing the redeemed Shares.

                           e. DETERMINATION OF THE NUMBER OF EACH HOLDER'S
SHARES TO BE REDEEMED. The number of Shares of Class A Preferred to be redeemed
from each holder thereof in redemptions hereunder shall be the number of Shares
of Class A Preferred determined by multiplying the total number of Shares of
Class A Preferred to be redeemed times a fraction, the numerator of which shall
be the total number of Shares of Class A Preferred then held by such holder and
the denominator of which shall be the total number of Shares of Class A
Preferred then outstanding.

                           f. DIVIDENDS AFTER REDEMPTION DATE. No Share shall be
entitled to any dividends accruing after the date on which the Liquidation Value
of such Share (plus all accrued and unpaid dividends thereon) is paid to the
holder of such Share. On such date, all rights of the holder of such Share shall
cease, and such Share shall no longer be deemed to be issued and outstanding.

                           g. REDEEMED OR OTHERWISE ACQUIRED SHARES. Any Shares
which are redeemed or otherwise acquired by the Corporation shall be canceled
and retired to authorized but unissued shares and shall not be reissued, sold or
transferred.

                           h. OTHER REDEMPTIONS OR ACQUISITIONS. The Corporation
shall not, nor shall it permit any Subsidiary to, redeem or otherwise acquire
any Shares of Class A Preferred, except as expressly authorized herein.

                           i. SPECIAL REDEMPTIONS.

                                    (i) If a Change in Ownership has occurred or
the Corporation obtains knowledge that a Change in Ownership is proposed to
occur, the Corporation shall give prompt written notice of such Change in
Ownership describing in reasonable detail the material

                                      -5-

<PAGE>

terms and date of consummation thereof to each holder of Class A Preferred, but
in any event such notice shall not be given later than five days after the
occurrence of such Change in Ownership, and the Corporation shall give each
holder of Class A Preferred prompt written notice of any material change in the
terms or timing of such transaction. The holder or holders of a majority of the
Class A Preferred then outstanding may require the Corporation to redeem all or
any portion of the Class A Preferred 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 to the Corporation of such election prior to
the later of (a) twenty-one days after receipt of the Corporation's notice and
(b) five days prior to the consummation of the Change in Ownership (the
"EXPIRATION DATE"). The Corporation shall give prompt written notice of any such
election to all other holders of Class A Preferred within five days after the
receipt thereof, and each such holder shall have until the later of (a) the
Expiration Date or (b) ten days after receipt of such second notice to request
redemption hereunder (by giving written notice to the Corporation) of all or any
portion of the Class A Preferred owned by such holder.

         Upon receipt of such election(s), the Corporation shall be obligated to
redeem the aggregate number of Shares specified therein on the later of (a) the
occurrence of the Change in Ownership or (b) five days after the Corporation's
receipt of such election(s). If any proposed Change in Ownership does not occur,
all requests for redemption in connection therewith shall be automatically
rescinded, or if there has been a material change in the terms or the timing of
the transaction, any holder of Class A Preferred may rescind such holder's
request for redemption by delivering written notice thereof to the Corporation
prior to the consummation of the transaction.

         The term "CHANGE IN OWNERSHIP" means any sale, transfer or issuance or
series of sales, transfers and/or issuances of Common Stock by the Corporation
or any holders thereof which results in any Person or group of Persons (as the
term "GROUP" is used under the Securities Exchange Act of 1934), other than the
holders of Common Stock or Class A Preferred as of the date of the Purchase
Agreement, owning more than 50% of the Common Stock outstanding at the time of
such sale, transfer or issuance or series of sales, transfers and/or issuances;
provided, however, that a Change in Ownership shall not occur as a result of a
Public Offering of Common Stock.

                                    (ii) If a Fundamental Change is proposed to
occur, the Corporation shall give written notice of such Fundamental Change
describing in reasonable detail the material terms and date of consummation
thereof to each holder of Class A Preferred not more than forty-five days nor
less than twenty days prior to the consummation of such Fundamental Change, and
the Corporation shall give each holder of Class A Preferred prompt written
notice of any material change in the terms or timing of such transaction. The
holder or holders of a majority of the Shares then outstanding may require the
Corporation to redeem all or any portion of the Class A Preferred 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 to the
Corporation of such election prior to the later of (a) ten days prior to the
consummation of the Fundamental Change or (b) ten days after receipt of notice
from the Corporation. The Corporation shall give prompt written notice of such
election to all other

                                      -6-

<PAGE>

holders of Class A Preferred (but in any event within five days prior to the
consummation of the Fundamental Change), and each such holder shall have until
two days after the receipt of such notice to request redemption (by written
notice given to the Corporation) of all or any portion of the Class A Preferred
owned by such holder.

         Upon receipt of such election(s), the Corporation shall be obligated to
redeem the aggregate number of Shares specified therein upon the consummation of
such Fundamental Change. If any proposed Fundamental Change does not occur, all
requests for redemption in connection therewith shall be automatically
rescinded, or if there has been a material change in the terms or the timing of
the transaction, any holder of Class A Preferred may rescind such holder's
request for redemption by delivering written notice thereof to the Corporation
prior to the consummation of the transaction.

         The term "FUNDAMENTAL CHANGE" means (a) any sale or transfer of more
than 50% of the assets of the Corporation and its Subsidiaries on a consolidated
basis (measured either by book value in accordance with generally accepted
accounting principles consistently applied or by fair market value determined in
the reasonable good faith judgment of the Corporation's Board of Directors) in
any transaction or series of transactions (other than sales in the ordinary
course of business) and (b) any merger or consolidation to which the Corporation
is a party, except for a merger in which the Corporation is the surviving
corporation, the terms of the Class A Preferred are not changed and the Class A
Preferred is not exchanged for cash, securities or other property, and after
giving effect to such merger, the holders of the Corporation's outstanding
capital stock possessing a majority of the voting power (under ordinary
circumstances) to elect a majority of the Corporation's Board of Directors
immediately prior to the merger shall continue to own the Corporation's
outstanding capital stock possessing the voting power (under ordinary
circumstances) to elect a majority of the Corporation's Board of Directors.

receipt requested and postage prepaid, or by reputable overnight courier
service, charges prepaid, and shall be deemed to have been given when so mailed
or sent (i) to the Corporation, at its principal executive offices and (ii) to
any Class A or Class B stockholder, at such holders address as it appears in the
stock records of the Corporation (unless otherwise indicated by any such
holder).

         F. Reverse Stock Split

                  1. MECHANICS. Effective upon the filing of this Restated
Certificate of Incorporation, each 2.85 shares of Common Stock issued and
outstanding shall be automatically changed into and combined as one fully paid
and nonassessable share of Common Stock pursuant to a reverse stock split,
subject to the treatment of fractional share interests as described below (the
"Reverse Stock Split"). Such change and combination shall not change the par
value per share of the shares changed and combined, which par value shall remain
$.0005 per share.

                  2. CERTIFICATES. Promptly after the filing of this Restated
Certificate of Incorporation, the Corporation shall deliver to each holder of
issued and outstanding shares of Common Stock which surrender for cancellation,
a certificate or certificates representing outstanding shares of Common Stock
prior to the Reverse Stock Split, a certificate or certificates representing the
number of shares of Common Stock issuable by reason of the Reverse Stock Split
in the name of such holder. This issuance of certificates for shares of Common
Stock upon the Reverse Stock Split shall be made without charge for any issuance
tax in respect thereof or other cost incurred by the Corporation in connection
with such Reverse Stock Split and the related issuance of shares of Common
Stock. Until surrendered as provided herein, from and after the filing of this
Restated Certificate of Incorporation, certificates representing outstanding
shares of Common Stock prior to the Reverse Stock Split shall thereupon be
deemed for all corporate purposes to evidence ownership of the number of shares
of Common Stock into which the Common Stock shall have been changed and combined
by reason of the Reverse Stock Split, subject to the treatment of fractional
share interests as described below.

                  3. FRACTIONAL SHARES. No fractional shares of Common Stock
shall be created or outstanding upon the Reverse Stock Split. Any holder of
Common Stock who by reason of the Reverse Stock Split would have been entitled
to receive a fraction of a share of Common Stock by reason of the Reverse Stock
Split, shall receive cash from the Corporation for his fractional interest in an
amount equal to the percentage of a share represented by such fractional
interest multiplied by the fair market value of one share of Common Stock of the
Corporation as established by the Corporation's Board of Directors in good
faith.

         FIFTH: The business and affairs of the Corporation shall be managed by
or under the direction of the Board of Directors. The Board of Directors may
exercise all such authority and powers of the Corporation and do all such lawful
acts and things as are not by statute or this

                                      -9-

<PAGE>

Restated Certificate of Incorporation directed or required to be exercised or
done by the stockholders.

                  A. DIRECTORS. The number of directors of the Corporation shall
be established as set forth in the Amended and Restated By-laws of the
Corporation, but in no event shall the number of directors be fewer than three
(3) nor more than eleven (11). Any change to the number of directors set forth
herein may only be made by amendment to this Article FIFTH. No such change shall
affect the term of any director then in office. No director need be a
stockholder. Each director elected shall hold office until a successor is duly
elected and qualified or until his or her earlier death, resignation or removal
as hereinafter provided.

                  B. NEWLY CREATED DIRECTORSHIPS AND VACANCIES. Subject to the
rights of the holders of any class or series of Preferred Stock then
outstanding, newly created directorships resulting from any increase in the
number of directors or any vacancies in the Board of Directors resulting from
death, resignation, retirement, disqualification, removal from office or any
other cause may be filled by the Board of Directors, provided that a quorum is
then in office and present, or by a majority of the directors then in office, if
less than a quorum is then in office, or by the sole remaining director.
Directors elected to fill a newly created directorship or other vacancies shall
hold office until such director's successor has been duly elected and qualified
or until his or her earlier death, resignation or removal as hereinafter
provided.

                  C. REMOVAL OF DIRECTORS. Subject to the rights of the holders
of any class or series of Preferred Stock then outstanding, the directors or any
director may be removed from office at any time, at a meeting called for that
purpose, and only by the affirmative vote of the holders of at least 66-2/3% of
the voting power of all shares of the Corporation entitled to vote generally in
the election of directors, voting together as a single class.

                  D. RIGHTS OF HOLDERS OF PREFERRED STOCK. Notwithstanding the
foregoing provisions of this Article FIFTH, whenever the holders of any one or
more classes or series of Preferred Stock issued by the Corporation shall have
the right, voting separately by class or series, to elect directors at an annual
or special meeting of stockholders, the election, term of office, filling of
vacancies and other features of such directorships shall be governed by the
rights and preferences of such Preferred Stock as set forth in this Restated
Certificate of Incorporation or in the resolution or resolutions of the Board of
Directors relating to the issuance of such Preferred Stock.

         SIXTH:  The Corporation is to have perpetual existence.

         SEVENTH: The Board of Directors is expressly authorized to adopt, amend
or repeal the by-laws of the Corporation. Any by-laws made by the directors
under the powers conferred hereby may be amended or repealed by the directors or
by the stockholders. Notwithstanding the foregoing and anything contained in
this Restated Certificate of Incorporation to the contrary, the Amended and
Restated By-laws of the Company shall not be amended or repealed by the
stockholders, and no provision inconsistent therewith shall be adopted by the
stockholders, without the affirmative vote of the holders of 66-2/3% of the
voting power of all shares of the

                                      -10-

<PAGE>

Corporation entitled to vote generally in the election of directors, voting
together as a single class.

         EIGHTH: A director of the Corporation shall not be personally liable to
the Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director; PROVIDED, HOWEVER, that the foregoing shall not eliminate or
limit the liability of a director (i) for any breach of the director's duty of
loyalty to the Corporation or its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the DGCL or (iv) for any transaction from which
the director derived an improper personal benefit. If the DGCL is hereafter
amended to permit further elimination or limitation of the personal liability of
directors, then the liability of a director of the Corporation shall be
eliminated or limited to the fullest extent permitted by the DGCL as so amended.
Any repeal or modification of this Article EIGHTH by the stockholders of the
Corporation or otherwise shall not adversely affect any right or protection of a
director of the Corporation existing at the time of such repeal or modification
with respect to acts or omissions occurring prior to such repeal or
modification.

         NINTH: Each person who was or is made a party or is threatened to be
made a party to or is involved (including, without limitation, as a witness) in
any actual or threatened action, suit or proceeding, whether civil, criminal,
administrative or investigative (hereinafter a "Proceeding"), by reason of the
fact that he is or was a director or officer of the Corporation or is or was
serving at the request of the Corporation as a director or officer of another
corporation or of a partnership, joint venture, trust or other enterprise,
including service with respect to an employee benefit plan (hereinafter an
"Indemnitee"), whether the basis of such Proceeding is alleged action in an
official capacity as a director or officer or in any other capacity while so
serving, shall be indemnified and held harmless by the Corporation to the
fullest extent authorized by the DGCL, as the same exists or may hereafter be
amended (but, in the case of any such amendment, only to the extent that such
amendment permits the Corporation to provide broader indemnification rights than
said law permitted the Corporation to provide prior to such amendment), or by
other applicable law as then in effect, against all expense, liability and loss
(including attorneys' fees and related disbursements, judgments, fines, excise
taxes or penalties under the Employee Retirement Income Security Act of 1974, as
amended from time to time ("ERISA"), penalties and amounts paid or to be paid in
settlement) actually and reasonably incurred or suffered by such Indemnitee in
connection therewith, and such indemnification shall continue as to a person who
has ceased to be a director, officer, partner, member or trustee and shall inure
to the benefit of his or her heirs, executors and administrators. Each person
who is or was serving as a director or officer of a subsidiary of the
Corporation shall be deemed to be serving, or have served, at the request of the
Corporation.

                  A. PROCEDURE. Any indemnification under this Article NINTH
(unless ordered by a court) shall be made by the Corporation only as authorized
in the specific case upon a determination that indemnification of the director
or officer is proper in the circumstances because he has met the applicable
standard of conduct set forth in the DGCL, as the same exists or hereafter may
be amended (but, in the case of any such amendment, only to the extent that such
amendment permits the Corporation to provide broader indemnification rights than
said law

                                      -11-

<PAGE>

permitted the Corporation to provide prior to such amendment). Such
determination shall be made with respect to a person who is a director or
officer at the time of such determination (a) by a majority vote of the
directors who were not parties to such Proceeding (the "Disinterested
Directors"), even though less than a quorum, (b) by a committee of Disinterested
Directors designated by a majority vote of such Disinterested Directors, even
though less than a quorum, (c) if there are no such directors, or if such
directors so direct, by independent legal counsel in a written opinion, or (d)
by the stockholders.

                  B. ADVANCES FOR EXPENSES. Costs, charges and expenses
(including attorneys' fees) incurred by a director or officer of the Corporation
in defending a Proceeding shall be paid by the Corporation in advance of the
final disposition of such Proceeding upon receipt of an undertaking by or on
behalf of the director or officer to repay all amounts so advanced in the event
that it shall ultimately be determined that such director or officer is not
entitled to be indemnified by the Corporation as authorized in this Article
NINTH. The majority of the Disinterested Directors may, in the manner set forth
above, and upon approval of such director or officer of the Corporation,
authorize the Corporation's counsel to represent such person, in any Proceeding,
whether or not the Corporation is a party to such Proceeding.

                  C. PROCEDURE FOR INDEMNIFICATION. Any indemnification or
advance of costs, charges and expenses under this Article NINTH shall be made
promptly, and in any event within 60 days upon the written request of the
director or officer, and shall be accompanied by a written undertaking by or on
behalf of Indemnitee to repay such amount if it shall ultimately be determined
that Indemnitee is not entitled to be indemnified therefor pursuant to the terms
of this Article NINTH. The right to indemnification of advances as granted by
this Article NINTH shall be enforceable by the director or officer in any court
of competent jurisdiction, if the Corporation denies such request, in whole or
in part, or if no disposition thereof is made within 60 days. Such person's
costs and expenses incurred in connection with successfully establishing his
right to indemnification, in whole or in part, in any such action shall also be
indemnified by the Corporation. It shall be a defense to any such action (other
than an action brought to enforce a claim for the advance of costs, charges and
expenses under this Article NINTH where the required undertaking, if any, has
been received by the Corporation) that the claimant has not met the standard of
conduct set forth in the DGCL, as the same exists or hereafter may be amended
(but, in the case of any such amendment, only to the extent that such amendment
permits the Corporation to provide broader indemnification rights than said law
permitted the Corporation to provide prior to such amendment), but the burden of
proving such defense shall be on the Corporation. Neither the failure of the
Corporation (including its Board of Directors, its independent legal counsel and
its stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he has met the applicable standard of conduct set forth in the DGCL, as
the same exists or hereafter may be amended (but, in the case of any such
amendment, only to the extent that such amendment permits the Corporation to
provide broader indemnification rights that said law permitted the Corporation
to provide prior to such amendment), nor the fact that there has been an actual
determination by the Corporation (including its Board of Directors, its
independent legal counsel and its stockholders) that the claimant has not met
such applicable standard of

                                      -12-

<PAGE>

conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.

                  D. OTHER RIGHTS; CONTINUATION OF RIGHT TO INDEMNIFICATION. The
indemnification and advancement of expenses provided by this Article NINTH shall
not be deemed exclusive of any other rights to which a person seeking
indemnification or advancement of expenses may be entitled under any law (common
or statutory), by-law, agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding office or while employed by or acting
as agent for the Corporation, and shall continue as to a person who has ceased
to be a director or officer, and shall inure to the benefit of the estate,
heirs, executors and administrators of such person. All rights to
indemnification under this Article NINTH shall be deemed to be a contract
between the Corporation and each director or officer of the Corporation who
serves or served in such capacity at any time while this Article NINTH is in
effect. Any repeal or modification of this Article NINTH or any repeal or
modification of relevant provisions of the DGCL or any other applicable laws
shall not in any way diminish any rights to indemnification of such director or
officer or the obligations of the Corporation arising hereunder with respect to
any Proceeding arising out of, or relating to, any actions, transactions or
facts occurring prior to the final adoption of such modification or repeal. For
the purposes of this Article NINTH, references to "the Corporation" include all
constituent corporations absorbed in a consolidation or merger as well as the
resulting or surviving corporation, so that any person who is or was a director
or officer of such a constituent corporation or is or was serving at the request
of such constituent corporation as a director or officer of another corporation,
partnership, joint venture, trust or other enterprise shall stand in the same
position under the provisions of this Article NINTH, with respect to the
resulting or surviving corporation, as he would if he had served the resulting
or surviving corporation in the same capacity.

                  E. INSURANCE. The Corporation shall have power to purchase and
maintain insurance on behalf of any person who is or was or has agreed to become
a director or officer of the Corporation, or is or was serving at the request of
the Corporation as a director or officer of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted against
him and incurred by him or on his behalf in any such capacity, or arising out of
his status as such, whether or not the Corporation would have the power to
indemnify him against such liability under the provisions of this Article NINTH,
PROVIDED, HOWEVER, that such insurance is available on acceptable terms, which
determination shall be made by a vote of a majority of the Board of Directors.

                  F. SAVINGS CLAUSE. If this Article NINTH or any portion hereof
shall be invalidated on any ground by any court of competent jurisdiction, then
the Corporation shall nevertheless indemnify or advance expenses to each person
entitled to indemnification or advancement of expenses, as the case may be, as
to all expense, liability and loss (including attorneys' fees and related
disbursements, judgments, fines, ERISA excise taxes and penalties, penalties and
amounts paid or to be paid in settlement) actually and reasonably incurred or
suffered by such person and for which indemnification or advancement of
expenses, as the case may be, is available to such person pursuant to this
Article NINTH to the full extent permitted by

                                      -13-

<PAGE>

any applicable portion of this Article NINTH that shall not have been
invalidated and to the full extent permitted by applicable law.

         TENTH: The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Restated Certificate of Incorporation, in
the manner now or hereafter prescribed herein and by the laws of the State of
Delaware, and all rights conferred upon stockholders herein are granted subject
to this reservation.

                                    * * * * *

         This Restated Certificate of Incorporation has been duly adopted by the
written consent of the stockholders of the Corporation in accordance with the
provisions of Sections 228, 242 and 245 of the DGCL, as amended.

Board of Directors
AppNet Systems, Inc.

Bethesda, Maryland  20817

Gentlemen:

         We are acting as special counsel for AppNet Systems, Inc., a Delaware
corporation (the "Company"), in connection with the initial public offering (the
"Offering") pursuant to the Registration Statement on Form S-1 (File No.
333-75205) filed on March 29, 1999, as amended (the "Registration Statement")
under the Securities Act of 1933, as amended (the "Act") covering 6,000,000
shares of the Company's common stock, par value $.0005 per share (the "Shares"),
and an over-allotment option of up to 900,000 shares of the Company's common
stock, par value $.0005 per share (the "Additional Shares"). All assumptions and
statements of reliance herein have been made without any independent
investigation or verification on our part except to the extent otherwise
expressly stated, and we express no opinion with respect to the subject matter
or accuracy of such assumptions or items relied upon.

         In connection with this opinion, we have (i) investigated such
questions of law, (ii) examined originals or certified, conformed or
reproduction copies of such agreements, instruments, documents and records of
the Company and its subsidiaries, such certificates of public officials,
officers or other representatives of the Company and its subsidiaries and other
persons and such other documents and (iii) received such information from
officers and representatives of the Company and others as we have deemed
necessary or appropriate for the purposes of this opinion.

         In all such examinations, we have assumed the legal capacity of all
natural persons executing documents (other than the capacity of officers of the
Company executing documents in such capacity), the genuineness of all
signatures, the authenticity of original and certified documents, and the

qualifications and assumptions set forth herein, we are of the opinion that (i)
the Shares to be offered by the Company, when issued, delivered and paid for as

         1A. AUTHORIZATION OF THE STOCK. The Company shall authorize the
issuance and sale to the Purchasers of up to 96,500 shares of its Class A
Cumulative Redeemable Preferred Stock, par value $.01 per share (the "CLASS A

         1B.      PURCHASE AND SALE OF THE STOCK.

                  (a) PURCHASE AND SALE BY GTCR. (i) At the Closing (as defined
         in Section 1C below), the Company shall sell to GTCR and, subject to
         the terms and conditions set forth herein, GTCR shall purchase from the
         Company 32,279,750 shares of Common Stock at a price of $0.1055 per
         share (together with the shares purchased by Smart Technology pursuant
         to Section 1B(b)(i), the "PURCHASED SHARES").

                  (ii) The Company operates a business in the information
         technology services industry and intends to make acquisitions which are
         synergistic with or otherwise complementary to its existing business.
         GTCR is committing to providing $98 million (including the amount
         invested to purchase the Purchased Shares) in equity financing to the
         Company as the equity portion of the debt and equity financing
         necessary to fund the Company's working capital and such acquisitions,
         in each case as approved by the Company's board of directors (the
         "BOARD") and GTCR (an "APPROVED USE"). In order to implement the
         foregoing, GTCR shall purchase from time to time after the Closing,
         upon the written request of the Board in connection with such an

         the number of shares so purchased by GTCR. At the time of any such
         purchase, the Company shall provide notice of such purchase to Smart

         Section 1B(b)(i) by


<PAGE>

         cancellation of a pro rata portion of the principal amount of the Smart
         Technology Loan equal to such purchase price. At the Closing, Smart
         Technology shall surrender to the Company the existing promissory note
         evidencing the Smart Technology Loan and shall terminate the Loan
         Agreement between the Company and Smart Technology dated April 23,
         1998, and the Company shall (i) pay Smart Technology the accrued
         interest on the Smart Technology Loan as of Closing and (ii) issue to
         Smart Technology a subordinated note (the "SUBORDINATED NOTE") with an
         interest rate of 12% per annum representing the remaining amount due
         under the Smart Technology Loan, in the form attached hereto as EXHIBIT
         B.

                  (ii) Upon the purchase from time to time by GTCR of up to
         94,570 shares of Class A Preferred pursuant to Section 1B(a) of the
         Purchase Agreement, Smart Technology will purchase, and the Company
         will sell up to an aggregate of 1,930 shares of Class A Preferred at a
         price of $1,000.00 per share (as adjusted from time to time as a result
         of stock splits, stock dividends, recapitalizations and similar
         events). The number of shares of Class A Preferred to be sold by the
         Company and purchased by Smart Technology at any time shall equal (i)
         1,930 shares of Class A Preferred MULTIPLIED BY (ii) a fraction (A) the
         numerator of which will be the number of shares of Class A Preferred to
         be concurrently purchased by GTCR and (B) the denominator of which will
         be 94,570 shares. At the time of any such purchase, Smart Technology
         shall be entitled to receive, and the Company shall be obligated to
         deliver, the representations, warranties, information and documentation
         provided to GTCR pursuant to Section1B(a)(ii). At the time of any such
         purchase, the Company will deliver to Smart Technology the certificates
         representing such shares of Class A Preferred purchased by Smart
         Technology. At the time of any such purchase, Smart Technology shall
         reaffirm substantially the representations in Sections 6F and 6G of
         this Agreement. Smart Technology shall pay the purchase price for the
         shares purchased pursuant to this Section 1B(b)(ii), first, by
         cancellation of a pro rata portion of the principal amount of the Smart
         Technology Loan equal to such purchase price until the principal amount
         due under the Smart Technology Loan has been reduced to zero, and,
         thereafter, by delivery to the Company of a cashier's or certified
         check or a wire transfer of funds in the aggregate amount of the price
         per share of such shares MULTIPLIED BY the number of shares so
         purchased by Smart Technology.

                  (iii) In the event that Smart Technology does not purchase for
         any reason (regardless of any default or breach by the Company or any
         of its Subsidiaries) the shares of Class A Preferred to be purchased by
         it pursuant to Section 1B(b)(ii) above within 30 days of receipt of a
         GTCR Purchase Notice, the Company shall have the right to purchase, in
         which event Smart Technology and its transferees shall be obligated to

         Section  4. TRANSFER OF RESTRICTED SECURITIES.

                  (i) Restricted Securities are transferable only pursuant to
         (a) public offerings registered under the Securities Act, (b) Rule 144
         or Rule 144A of the Securities and Exchange Commission (or any similar
         rule or rules then in force) if such rule or rules are available and
         (c) subject to the conditions specified in Section (ii) below, any
         other legally available means of transfer.

                  (ii) In connection with the transfer of any Restricted
         Securities (other than a transfer described in Section 4(i)(a) above),
         the holder thereof shall deliver written notice to the Company
         describing in reasonable detail the transfer or proposed transfer,
         together with an opinion of Kirkland & Ellis or other counsel which (to
         the Company's reasonable satisfaction) is knowledgeable in securities
         law matters to the effect that such transfer of Restricted Securities
         may be effected without registration of such Restricted Securities
         under the Securities Act. In addition, if the holder of the Restricted
         Securities delivers to the Company an opinion of Kirkland & Ellis or
         such other counsel that no subsequent transfer of such Restricted
         Securities shall require registration under the Securities Act, the
         Company shall promptly upon such contemplated transfer deliver new
         certificates for such Restricted Securities which do not bear the
         Securities Act legend set forth in Section 4(iv). If the Company is not
         required to deliver new certificates for such Restricted Securities not
         bearing such legend, the holder thereof shall not transfer the same
         until the prospective transferee has confirmed to the Company in
         writing its acknowledgment of, and agreement to be bound by, the
         conditions and representations contained in this Section, Section 6F
         and Section 6G. This Section 4(ii) shall not apply to any transfer of
         any Restricted Securities between and among GTCR and its Affiliates.

                  (iii) Upon the request of any Purchaser, the Company shall
         promptly supply to any Purchaser or its prospective transferees all
         information regarding the Company required to be delivered in
         connection with a transfer pursuant to Rule 144A of the Securities and
         Exchange Commission.

         under the lease or sublease; (c) neither the Company and its
         Subsidiaries nor any Seller has assigned, transferred, conveyed,
         mortgaged, deeded in trust or encumbered any interest in the leasehold
         or subleasehold; (d) all buildings, improvements or other property
         leased or subleased thereunder are supplied with utilities and other
         services necessary for the operation thereof (including gas,
         electricity, water, telephone, sanitary and storm sewer, and access to
         public roads); and (e) with respect to each sublease, to the Knowledge
         of the Company the representations and warranties set forth in
         subparagraphs (a) through (d) above are true and correct with respect

         thereof. No damage or destruction has occurred with respect to any of
         the Leased Real Property that, individually or in the aggregate, has

         and its Subsidiaries of the Leased Real Property is dependent on a
         nonconforming use or other approval from a governmental authority, the
         absence of which would significantly limit the use of any of the
         properties or assets in the operation of the business.

         the manner currently being used and operated.

         8C. CONSENT TO AMENDMENTS. Except as otherwise expressly provided
herein, the provisions of this Agreement may be amended and the Company may take
any action herein prohibited, or omit to perform any act herein required to be
performed by it, only if the Company has obtained the written consent of the
holders of a majority of the Investor Stock. In addition, any amendment of
Section 1B(b) of this Agreement shall require the written consent of Smart
Technology. No other course of dealing between the Company and the holder of any
Stock or any delay in exercising any rights hereunder or under the Second or
Third Restated Certificates of Incorporation shall operate as a waiver of any
rights of any such holders. For purposes of this Agreement, shares of Stock held
by the Company or any Subsidiaries shall not be deemed to be outstanding.

         8D. COMPLETE AGREEMENT. This Agreement, those documents expressly
referred to herein and other documents of even date herewith embody the complete
agreement and understanding among the parties and supersede and preempt any
prior understandings, agreements or representations by or among the parties,
written or oral, which may have related to the subject matter hereof in any way.

         8E. SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations and
warranties contained herein or made in writing by any party in connection
herewith shall survive the execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby, regardless of any
investigation made by any Purchaser or on its behalf, and shall terminate on the
second anniversary of this Agreement.

         8F. SUCCESSORS AND ASSIGNS. Except as otherwise expressly provided
herein, all covenants and agreements contained in this Agreement by or on behalf
of any of the parties hereto shall bind and inure to the benefit of the
respective successors and assigns of the parties hereto whether so expressed or
not. In addition, and whether or not any express assignment has been made, the
provisions of this Agreement which are for the Purchasers' benefit as a
purchaser

or holder of Stock are also for the benefit of, and enforceable by, any
subsequent holder of such Stock. The rights and obligations of GTCR under this
Agreement and the agreements contemplated hereby may be assigned at any time, in
whole or in part, to any investment fund managed by GTCR, or any successor
thereto; provided that (i) such investment fund has adequate capital to purchase
the rights and obligations to be assigned by the assigning party, (ii) such
investment fund provides the representations pursuant to Sections 6F and 6G of
this Agreement and (iii) the assigning party shall only assign its rights under
this Agreement to the assignee in proportion to the amount of stock to be
transferred by the assignor to the assignee (as compared to the total amount of
Company stock owned by the assignor).

         8G. GENERALLY ACCEPTED ACCOUNTING PRINCIPLES. Where any accounting
determination or calculation is required to be made under this Agreement or the
exhibits hereto, such determination or calculation (unless otherwise provided)
shall be made in accordance with GAAP, except that if because of a change in
GAAP the Company would have to alter a previously utilized accounting method or
policy in order to remain in compliance with GAAP, such determination or
calculation shall continue to be made in accordance with the Company's previous
accounting methods and policies.

         8H. SEVERABILITY. Whenever possible, each provision of this Agreement
shall 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 prohibited
by or invalid under applicable law, such provision shall be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of this Agreement.

         8I. COUNTERPARTS. This Agreement may be executed simultaneously in two
or more counterparts, any one of which need not contain the signatures of more
than one party, but all such counterparts taken together shall constitute one
and the same Agreement.

         8J. DESCRIPTIVE HEADINGS; INTERPRETATION. The descriptive headings of
this Agreement are inserted for convenience only and do not constitute a Section
of this Agreement. The use of the word "including" in this Agreement shall be by
way of example rather than by limitation.

         8K. GOVERNING LAW. The corporate law of Delaware shall govern all
issues concerning the relative rights of the Company and its stockholders. All
other questions concerning the construction, validity and interpretation of this
Agreement and the exhibits and schedules hereto shall be governed by and
construed in accordance with the internal laws of the State of Delaware, without
giving effect to any choice of law or conflict of law provision or rule (whether
of the State of Delaware or any other jurisdiction) that would cause the
application of the laws of any jurisdiction other than the State of Delaware.

and the Executive Fund, the "GTCR FUNDS").

                  WHEREAS, GTCR, Smart Technology and AppNet entered into a
Purchase Agreement dated as of June 29, 1998 (the "PURCHASE AGREEMENT");

                  WHEREAS, pursuant to a Stock Purchase Agreement by and among
GTCR, GTCR Fund VI, the Executive Fund and the Associates Fund dated July 1,
1998 (the "STOCK PURCHASE AGREEMENT"), each of the GTCR Funds purchased from
GTCR the following number of shares of Common Stock at a price of $0.1055 per
share: (i) GTCR Fund VI, 31,978,095 shares; (ii) Executive Fund, 229,251 shares;
and (iii) Associates Fund, 72,404 shares (the "GTCR TRANSFER");

                  WHEREAS, in connection with the GTCR Transfer, GTCR assigned
to the GTCR Funds the obligation of GTCR to purchase shares of AppNet's Class A
Cumulative Redeemable Preferred Stock, par value $.01 per share (the "CLASS A

STOCK CONSIDERATION");

                  WHEREAS, the Preferred Stock Consideration affects the
commitments of the GTCR Funds and Smart Technology to purchase shares of Class A
Preferred pursuant to the terms of the Purchase Agreement;

         NOW, THEREFORE, in consideration of the premises, the mutual covenants
and agreements set forth herein, and for the purpose of setting forth the terms
and conditions of this Amendment, the parties, intending to be bound, hereby
agree as follows:

         1. INCORPORATION OF PURCHASE AGREEMENT. All capitalized terms which are
not defined herein shall have the same meanings as set forth in the Purchase
Agreement. Except as specifically set forth herein, the Purchase Agreement shall
remain in full force and effect and its provisions shall be binding on the
parties hereto.


<PAGE>

         2. AMENDMENT OF PURCHASE AGREEMENT. The Purchase Agreement is hereby
amended as follows:

         The second and third sentences of Section 1B(a)(ii) of the Purchase
Agreement are amended to read as follows:

         GTCR is committing to providing $86,627,114 (including the amount
         invested to purchase the Purchased Shares) in equity financing to the
         Company as the equity portion of the debt and equity financing
         necessary to fund the Company's working capital and such acquisitions,
         in each case as approved by the Company's board of directors (the
         "BOARD") and GTCR (an "APPROVED USE"). In order to implement the
         foregoing, GTCR shall purchase from time to time after the Closing,
         upon the written request of the Board in connection with such an
         Approved Use, up to 83,221.6 shares of Class A Preferred at a price of
         $1,000 per share as adjusted from time to time as a result of stock
         dividends, stock splits, recapitalization and similar events).

         The first two sentences of Section 1B(b)(ii) of the Purchase Agreement
are amended to read as follows:

         Upon the purchase from time to time by GTCR of up to 83,221.6 shares of
         Class A Preferred pursuant to Section 1B(a) of the Purchase Agreement,
         Smart Technology will purchase, and the Company will sell up to an
         aggregate of 1,698.4 shares of Class A Preferred at a price of
         $1,000.00 per share (as adjusted from time to time as a result of stock
         splits, stock dividends, recapitalizations and similar events). The
         number of shares of Class A Preferred to be sold by the Company and
         purchased by Smart Technology at any time shall equal (i) 1,698.4
         shares of Class A Preferred MULTIPLIED BY (ii) a fraction (A) the
         numerator of which will be the number of shares of Class A Preferred to
         be concurrently purchased by GTCR and (B) the denominator of which will
         be 83,221.6 shares.

         3. EFFECTUATION. The amendments to the Purchase Agreement contemplated
by this Amendment shall be deemed effective upon the consummation of the
Proposed Merger without any further action required by the parties hereto.

         4. CHOICE OF LAW. The construction, validity, interpretation and
enforcement of this Amendment shall be governed by the internal law, and not the
law of conflicts, of the State of Delaware.

         5. COUNTERPARTS. This Amendment may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

                                    * * * * *

         consent of such Purchasers, unless such disclosure is required by
         applicable law or governmental regulations or by order of a court of

         then-previous disclosure the Company shall give written notice to such
         Purchasers describing in reasonable detail the proposed content of such

         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.

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

or (iv) willful violation of any law, rule or regulation (other than traffic

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

to constitute at least a majority of the members of the Board; PROVIDED,

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 other than the Board (a "Proxy Contest") including
by reason of any agreement intended to avoid or settle any Election Contest or
Proxy Contest; or

                                    corporation resulting from such merger or

price per Share under each Incentive Stock Option shall not be less than 100% of

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

portion thereof at any time.

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

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

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

Beneficiary within the period specified in Sections 5.5(a) or 5.5(c), as the
case may be.

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

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.

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.       OPTION GRANTS FOR NONEMPLOYEE DIRECTORS.

                  6.1 GRANT. Formula Options shall be granted (i) to a
Nonemployee Director who becomes a member of the Board after June __, 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 June ___, 1999 shall, upon becoming a Director, be
granted a Formula Option in respect of 5,000 Shares.

                           (b)      ANNUAL GRANT.  Each Nonemployee Director
shall be granted a Formula Option in respect of 5,000 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. Each Formula Option shall be fully vested and
exercisable on the date of grant; PROVIDED, HOWEVER, that the Optionee is a
Director on such date.

                  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 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)



                                      -15-
<PAGE>

months after such termination exercise his or her Formula Option, 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, 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 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 Option
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 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.

         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



                                      -16-
<PAGE>

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 Section 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 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



                                      -17-
<PAGE>

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 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 vested and 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



                                      -18-
<PAGE>

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 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



                                      -19-
<PAGE>

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 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



                                      -20-
<PAGE>

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 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



                                      -21-
<PAGE>

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 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



                                      -22-
<PAGE>

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 vested and 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 surrender, of the underlying Shares subject to the
Stock Appreciation Right or portion thereof surrendered and (ii) the Adjusted
Fair Market Value, on the date preceding the date of surrender, 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 surrendered. 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 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.

<PAGE>

                  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 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



                                      -25-
<PAGE>

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.

                  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



                                      -26-
<PAGE>

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. 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 remains
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



                                      -27-
<PAGE>

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 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



                                      -28-
<PAGE>

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
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.


                                      -29-
<PAGE>

                           (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.

                           (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



                                      -30-
<PAGE>

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, 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



                                      -31-
<PAGE>

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 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.


                                      -32-
<PAGE>

         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 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 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 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,



                                      -34-
<PAGE>

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, 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



                                      -35-
<PAGE>

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.

                  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 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



                                      -38-
<PAGE>

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.
