                               PROSPECTUS SUMMARY

    YOU SHOULD READ THE FOLLOWING SUMMARY TOGETHER WITH THE MORE DETAILED
INFORMATION AND OUR CONSOLIDATED FINANCIAL STATEMENTS AND RELATED NOTES
APPEARING ELSEWHERE IN THIS PROSPECTUS.

                            PREDICTIVE SYSTEMS, INC.

OUR BUSINESS

    We are a network consulting company focused on the design, performance,
management and security of complex computing networks. We utilize our
proprietary consulting methodology, BusinessFirst, to translate our clients'
strategic business objectives into sound technology solutions. Using our
BusinessFirst methodology, we demonstrate the business value of technology
solutions in specific and measurable terms, thereby enabling our clients to
incorporate objective and quantifiable analysis into their technology investment
decisions. As a result, our clients can gain a clear understanding of the
benefits that they will derive from their network technology investments and a
measure of certainty regarding how their technology investments will be
translated into quantifiable improvements to their business processes.

OUR SERVICES

    As an independent service provider, we provide our clients with unbiased
expertise that enables the design, implementation and management of optimal
technology solutions. We provide our services on either a project outsource or
collaborative consulting basis. Our project outsource services are primarily
based and measured against mutually agreed upon service offerings and provide
our clients with certainty of costs, delivery time and project scope. Our
collaborative consulting services enable our clients to utilize our extensive
expertise in order to extend their internal capabilities and to access our
methodologies.

    In addition to these services, we have developed an innovative service model
through which we deliver our clients productized services, which are
pre-packaged service products. Our service products are characterized by
pre-defined service offerings that have a pre-defined set of service
deliverables, a pre-defined pricing model and are implemented using a
pre-defined methodology. In contrast to our project outsource and collaborative
consulting services which provide our clients with services that are customized
for, and therefore unique to, each engagement, our service products are
typically provided with little or no modification. We believe that this unique
approach to network services further differentiates us from our competitors.

    Our consultants are organized into the following practice areas, which cover
the four cornerstones of network computing: network and systems management;
internetwork design and engineering; performance management; and information
security. This structure enables our consultants to gain in-depth expertise and
become intimately familiar with the best practices and methodologies identified
within each of those disciplines.

OUR MARKET

    We believe we are well-positioned to capitalize on global trends impacting
communications technology, primarily the acceptance and growth of the Internet
and private intranets. As a result of these trends, the demand for network
consulting services has grown dramatically. International Data Corporation, a
market research organization, estimates that the worldwide market for these
services will grow from $12.1 billion in 1998 to $25.5 billion by 2003. Although
there are many third-party service providers attempting to address this growing
market, including network equipment vendors, systems integrators, value-added
resellers and network consulting companies, we believe that few have the
requisite focus and expertise to address the multi-faceted issues surrounding
today's complex networking environments.

                                       4
<PAGE>
OUR STRATEGY

    Our goal is to become the leading provider of services for the design,
performance, management and security of complex networks. To achieve this goal,
we intend to pursue the following strategies:

    - continue to evolve our BusinessFirst methodology;

    - expand and enhance our service product offerings;

    - continue to attract and retain highly qualified consultants;

    - further increase our industry expertise; and

    - expand in existing and new geographic markets.

OUR CLIENTS

    We provide our services to a broad range of clients in many industries,
including communications services, financial services, network technology and
professional services. Our clients include Allied Signal; Bear Stearns;
Bloomberg; British Telecom; Cisco Systems; UUNET, an MCI WorldCom company;
Pfizer and Qwest. These clients, in the aggregate, accounted for approximately
60.2% of our revenues for the six months ended June 30, 1999 and 55.0% of our
revenues for the year ended December 31, 1998.

RECENT DEVELOPMENTS

    In September 1999, we completed the private placement of 1,242,000 shares of
our common stock to Cisco Systems, Inc. for $12.00 per share. In connection with
the investment, we have agreed to nominate a person designated by Cisco for
election to our Board of Directors so long as Cisco owns more than 750,000
shares of our common stock.

    In September 1999, we also completed the private placement of 94,867 and
18,133 shares of our common stock to General Atlantic Partners 57, L.P. and GAP
Coinvestment Partners II, L.P., respectively, for $12.00 per share.

OUR HISTORY

    We were organized as Predictive Holdings, Inc. in Delaware in February 1995.
In March 1999, in order to simplify our corporate organizational structure,
Predictive Holdings was merged into its wholly-owned subsidiary, Predictive
Systems, the surviving corporation.

    Since our inception, we have expanded our service offerings, evolved our
technology expertise and developed the scope of our business to address the most
critical network technology needs of the broad client base we serve. We have
continued to grow our client base by expanding geographically, and we have
supported this client base by attracting and retaining talented professionals at
all levels. As of August 31, 1999, our employee base had grown to 349 full-time
employees.

    Our principal executive offices are located at 145 Hudson Street, New York,
New York 10013. Our telephone number is (212) 219-4400. In addition, we maintain
offices in nine other locations: Atlanta, Georgia; Boston, Massachusetts;
Dallas, Texas; Florham Park, New Jersey; Herndon, Virginia; Pleasanton,
California; Santa Cruz, California; London, England; and Amsterdam, The
Netherlands.

                                  RISK FACTORS

    THIS OFFERING INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD CAREFULLY CONSIDER
THE RISKS DESCRIBED BELOW BEFORE YOU DECIDE TO BUY OUR COMMON STOCK. IF ANY OF
THE FOLLOWING RISKS ACTUALLY OCCUR, OUR BUSINESS, RESULTS OF OPERATIONS OR
FINANCIAL CONDITION WOULD LIKELY SUFFER. IN THIS CASE, THE MARKET PRICE OF OUR
COMMON STOCK COULD DECLINE, AND YOU COULD LOSE ALL OR PART OF YOUR INVESTMENT.

          RISKS RELATED TO OUR FINANCIAL CONDITION AND BUSINESS MODEL

OUR LIMITED OPERATING HISTORY, PARTICULARLY IN LIGHT OF OUR RECENT GROWTH, MAKES
IT DIFFICULT FOR YOU TO EVALUATE OUR BUSINESS AND TO PREDICT OUR FUTURE SUCCESS

    We commenced operations in February 1995 and therefore have only a limited
operating history for you to evaluate our business. Because of our limited
operating history, recent growth and the fact that many of our competitors have
longer operating histories, we believe that the prediction of our future success
is difficult. You should evaluate our chances of financial and operational
success in light of the risks, uncertainties, expenses, delays and difficulties
associated with operating a new business, many of which are beyond our control.
You should not rely on our historical results of operations as indications of
future performance. The uncertainty of our future performance and the
uncertainties of our operating in a new and expanding market increase the risk
that the value of your investment will decline.

BECAUSE MOST OF OUR REVENUES ARE GENERATED FROM A SMALL NUMBER OF CLIENTS, OUR
REVENUES ARE DIFFICULT TO PREDICT AND THE LOSS OF ONE COULD SIGNIFICANTLY REDUCE
OUR REVENUES

    During the six months ended June 30, 1999, each of Bear Stearns and Qwest
Communications accounted for 23.1% and 17.1%, respectively, of our revenues. Our
five largest clients accounted for 57.0% of our revenues for the six months
ended June 30, 1999. For the year ended December 31, 1998, our five largest
clients accounted for 54.9% of our revenues. If one of our major clients
discontinues or significantly reduces the use of our services, we may not
generate sufficient revenues to offset this loss of revenues and our net income
will decrease. In addition, the non-payment or late payment of amounts due from
a major client could adversely affect us.

OUR CLIENTS MAY TERMINATE THEIR CONTRACTS WITH US ON SHORT NOTICE

    Our services are often delivered pursuant to short-term arrangements and
most clients can reduce or cancel their contracts for our services without
penalty and with little or short notice. If a major client or a number of small
clients terminate our contracts or significantly reduce or modify their business
relationships with us, we may not be able to replace the shortfall in revenues.
Consequently, you should not predict or anticipate our future revenues based
upon the number of clients we have currently or the number and size of our
existing projects.

OUR OPERATING RESULTS MAY VARY FROM QUARTER TO QUARTER IN FUTURE PERIODS, AND AS
A RESULT, WE MAY FAIL TO MEET THE EXPECTATIONS OF OUR INVESTORS AND ANALYSTS,
WHICH MAY CAUSE OUR STOCK PRICE TO FLUCTUATE OR DECLINE

    Our operating results have varied from quarter to quarter. Our operating
results may continue to vary as a result of a variety of factors. These factors
include:

    - the loss of key employees;

    - the development and introduction of new service offerings;

    - reductions in our billing rates;

    - the miscalculation of resources required to complete new or ongoing
      projects;

                                       8
<PAGE>
    - the utilization of our workforce; and

    - the timing and extent of training.

    Many of these factors are beyond our control. Accordingly, you should not
rely on quarter-to-quarter comparisons of our results of operations as an
indication of our future performance. In addition, our operating results may be
below the expectations of public market analysts or investors in some future
quarter. If this occurs, the price of our common stock is likely to decline.

WE DERIVE A SUBSTANTIAL PORTION OF OUR REVENUES FROM FIXED-PRICE PROJECTS, UNDER
WHICH WE ASSUME GREATER FINANCIAL RISK IF WE FAIL TO ACCURATELY ESTIMATE THE
COSTS OF THE PROJECTS

    We derive a substantial portion of our revenues from fixed-price projects.
For the year ending December 31, 1998 and the six months ended June 30, 1999,
fixed-price projects accounted for 26.0% and 36.9% of our revenue, respectively.
We assume greater financial risks on a fixed-price project than on a
time-and-expense based project. If we miscalculate the resources or time we need
for these fixed-price projects, the costs of completing these projects may
exceed the price, which could result in a loss on the project and a decrease in
net income. Further, the average size of our contracts has increased in recent
quarters, resulting in a corresponding increase in our exposure to the financial
risks of fixed-price engagements. We recognize revenues from fixed-price
projects based on our estimate of the percentage of each project completed in a
reporting period. To the extent our estimates are inaccurate, the revenues and
operating profits, if any, that we report for periods during which we are
working on a fixed-price project may not accurately reflect the final results of
the project and we would be required to record an expense for these periods
equal to the amount by which our revenues were previously overstated.

OUR OPERATING RESULTS MAY FLUCTUATE DUE TO SEASONAL FACTORS WHICH COULD RESULT
IN GREATER THAN EXPECTED LOSSES

    Our results of operations may experience seasonal fluctuations as businesses
typically spend less on network management services during the summer and
year-end vacation and holiday periods. Additionally, as a large number of our
employees take vacation during these periods, our utilization rates during these
periods tend to be lower, which reduces our margins and operating income.
Accordingly, we may report greater than expected losses for these periods.

OUR LONG SALES CYCLE MAKES OUR REVENUES DIFFICULT TO PREDICT AND COULD CAUSE OUR
QUARTERLY OPERATING RESULTS TO BE BELOW THE EXPECTATIONS OF PUBLIC MARKET
ANALYSTS AND INVESTORS

    The timing of our revenues is difficult to predict because of the length and
variance of the time required to complete a sale. Before hiring us for a
project, our clients often undertake an extensive review process and may require
approval at various levels within their organization. Any delay due to a long
sales cycle could reduce our revenues for a quarter and cause our quarterly
operating results to be below the expectations of public market analysts or
investors. If this occurs, the price of our common is likely to decline.

WE MAY NEED TO RAISE ADDITIONAL CAPITAL TO GROW OUR BUSINESS, WHICH WE MAY NOT
BE ABLE TO DO

    Our future liquidity and capital requirements are difficult to predict
because they depend on numerous factors, including the success of our existing
and new service offerings and competing technological and market developments.
As a result, we may not be able to generate sufficient cash from our operations
to meet additional working capital requirements, support additional capital
expenditures or take advantage of acquisition opportunities. Accordingly, we may
need to raise additional capital in the future. Our ability to obtain additional
financing will be subject to a number of factors, including market conditions,
our operating performance and investor sentiment. These factors

                                       9
<PAGE>
may make the timing, amount, terms and conditions of additional financing
unattractive for us. If we are unable to raise additional funds when needed, our
ability to operate and grow our business could be impeded.

                    RISKS RELATED TO OUR STRATEGY AND MARKET

WE MAY HAVE DIFFICULTY MANAGING OUR EXPANDING OPERATIONS, WHICH MAY HARM OUR
  BUSINESS

    A key part of our strategy is to grow our business, however, our rapid
growth has placed a significant strain on our managerial and operational
resources. From January 1, 1997 to August 31, 1999, our staff increased from
approximately 123 to approximately 349 employees. To manage our growth, we must
continue to improve our financial and management controls, reporting systems and
procedures, and expand and train our work force. We may not be able to do so
successfully.

WE MAY NOT BE ABLE TO HIRE AND RETAIN QUALIFIED NETWORK SYSTEMS CONSULTANTS
WHICH COULD AFFECT OUR ABILITY TO COMPETE EFFECTIVELY

    Our continued success depends on our ability to identify, hire, train and
retain highly qualified network management consultants. These individuals are in
high demand and we may not be able to attract and retain the number of highly
qualified consultants that we need. If we cannot retain, attract and hire the
necessary consultants, our ability to grow, complete existing projects and bid
for new projects will be adversely affected.

COMPETITION IN THE NETWORK CONSULTING INDUSTRY IS INTENSE, AND THEREFORE WE MAY
LOSE PROJECTS TO OUR COMPETITORS

    Our market is intensely competitive, highly fragmented and subject to rapid
technological change. We expect competition to intensify and increase over time.
We may lose projects to our competitors, which could adversely affect our
business, results of operations and financial condition. In addition,
competition could result in lower billing rates and gross margins and could
require us to increase our spending on sales and marketing.

    We face competition from systems integrators, value added resellers, local
and regional network services firms, telecommunications providers, and network
equipment and computer systems vendors. These competitors may be able to respond
more quickly to new or emerging technologies and changes in client requirements
or devote greater resources to the expansion of their market share.

    Additionally, our competitors have in the past and may in the future form
alliances with various network equipment vendors that may give them an advantage
in implementing networks using that vendor's equipment.

    We also compete with internal information technology departments of current
and potential clients. To the extent that current or potential clients decide to
satisfy their needs internally, our business will suffer.

IF WE ARE UNABLE TO INTEGRATE OUR RECENT ACQUISITION OF NETWORK RESOURCE
CONSULTANTS AND COMPANY B.V. AND ANY OTHER FUTURE ACQUISITIONS, OUR BUSINESS MAY
BE DISRUPTED

    We recently acquired Network Resource Consultants and Company B.V., a
network consulting company based in The Netherlands. The integration of this and
other future acquisitions presents us with significant financial, managerial and
operational challenges. We may not be able to meet these challenges effectively.
To the extent our management is required to devote significant time and
attention to integrating the technology, operations and personnel of acquired
businesses, we may not be able to properly serve our current clients or attract
new clients. Any difficulties in integrating

                                       10
<PAGE>
acquisitions could disrupt our ongoing business, distract our management and
employees, increase our expenses and otherwise adversely affect our business.

IF WE ARE UNABLE TO FIND SUITABLE ACQUISITION CANDIDATES, OUR GROWTH COULD BE
IMPEDED

    A component of our growth strategy is the acquisition of, or investment in,
complementary businesses, technologies, services or products. Our ability to
identify and invest in suitable acquisition and investment candidates on
acceptable terms is crucial to this strategy. We may not be able to identify,
acquire or make investments in promising acquisition candidates on acceptable
terms. Moreover, in pursuing acquisition and investment opportunities, we may be
in competition with other companies having similar growth and investment
strategies. Competition for these acquisitions or investment targets could also
result in increased acquisition or investment prices and a diminished pool of
businesses, technologies, services or products available for acquisition or
investment.

OUR ACQUISITION STRATEGY COULD HAVE AN ADVERSE EFFECT ON CLIENT SATISFACTION AND
OUR OPERATING RESULTS

    Acquisitions involve a number of risks, including:

    - adverse effects on our reported operating results due to accounting
      charges associated with acquisitions;

    - increased expenses, including compensation expense resulting from newly
      hired employees; and

    - potential disputes with the sellers of acquired businesses, technologies,
      services or products.

    Client dissatisfaction or performance problems with an acquired business,
technology, service or product could also have a material adverse impact on our
reputation as a whole. In addition, any acquired business, technology, service
or product could significantly underperform relative to our expectations.

COMPETITION FOR EXPERIENCED PERSONNEL IS INTENSE AND OUR INABILITY TO RETAIN KEY
PERSONNEL COULD INTERRUPT OUR BUSINESS AND ADVERSELY AFFECT OUR GROWTH

    Our future success depends, in significant part, upon the continued service
and performance of our senior management and other key personnel, in particular
Ronald G. Pettengill, Jr., our Chairman and Chief Executive Officer, and Robert
L. Belau, our President. Losing the services of any of these individuals would
impair our ability to effectively deliver our services and manage our company,
and to carry out our business plan. In addition, competition for qualified
personnel in the network consulting industry is intense and we may not be
successful in attracting and retaining these personnel. There may be only a
limited number of persons with the requisite skills to serve in these positions
and it may become increasingly difficult to hire these persons. Our business
will suffer if we encounter delays in hiring additional personnel.

OUR INTERNATIONAL EXPANSION EFFORTS, WHICH ARE A KEY PART OF OUR GROWTH
STRATEGY, MAY NOT BE SUCCESSFUL

    We expect to expand our international operations and international sales and
marketing efforts. Recently, we commenced operations in England. In addition, in
August 1999, we acquired Network Resource Consultants and Company, a network
consulting company based in The Netherlands. We have had limited experience in
marketing, selling and distributing our services internationally. We may not be
able to maintain and expand our international operations or successfully market
our services internationally. Failure to do so may negatively affect our
business, as well as our ability to grow.

                                       11
<PAGE>
OUR BUSINESS MAY SUFFER IF WE FAIL TO ADAPT APPROPRIATELY TO THE CHALLENGES
ASSOCIATED WITH OPERATING INTERNATIONALLY

    Operating internationally may require us to modify the way we conduct our
business and deliver our services in these markets.

    We anticipate that we will face the following challenges internationally:

    - the burden and expense of complying with a wide variety of foreign laws
      and regulatory requirements;

    - potentially adverse tax consequences;

    - longer payment cycles and problems in collecting accounts receivable;

    - technology export and import restrictions or prohibitions;

    - tariffs and other trade barriers;

    - difficulties in staffing and managing foreign operations;

    - cultural and language differences;

    - fluctuations in currency exchange rates; and

    - seasonal reductions in business activity during the summer months in
      Europe.

    If we do not appropriately anticipate changes and adapt our practices to
meet these challenges, our growth could be impeded and our results of operations
could suffer.

IF WE DO NOT KEEP PACE WITH TECHNOLOGICAL CHANGES, OUR SERVICES MAY BECOME LESS
COMPETITIVE AND OUR BUSINESS WILL SUFFER

    Our market is characterized by rapidly changing technologies, frequent new
product and service introductions and evolving industry standards. As a result
of the complexities inherent in today's computing environments, we face
significant challenges in remaining abreast of such changes and product
introductions. If we cannot keep pace with these changes, we will not be able to
meet our clients' increasingly sophisticated network management needs and our
services will become less competitive.

    Our future success will depend on our ability to:

    - keep pace with continuing changes in industry standards, information
      technology and client preferences;

    - respond effectively to these changes; and

    - develop new services or enhance our existing services.

    We may be unable to develop and introduce new services or enhancements to
existing services in a timely manner or in response to changing market
conditions or client requirements.

IF THE USE OF LARGE-SCALE, COMPLEX NETWORKS DOES NOT CONTINUE TO GROW, WE MAY
NOT BE ABLE TO SUCCESSFULLY INCREASE OR MAINTAIN OUR CLIENT BASE AND REVENUES

    To date, a majority of our revenues have been from network management
services related to large-scale, complex networks. We believe that we will
continue to derive a majority of our revenues from providing network design,
performance, management and security services. As a result, our future success
is highly dependent on the continued growth and acceptance of large-scale,
complex computer networks and the continued trend among our clients to use
third-party service providers. If the growth

                                       12
<PAGE>
of the use of enterprise networks does not continue or declines, our business
may not grow and our revenues may decline.

IF THE INTERNET DOES NOT GROW AND CONTINUE TO DEVELOP AS A VIABLE BUSINESS TOOL,
DEMAND FOR OUR SERVICES AND OUR REVENUES MAY DECLINE

    The growing demand for network management services has been driven in part
by the growth of the Internet. The Internet may not prove to be a viable
commercial marketplace because of:

    - inadequate development of the necessary infrastructure;

    - lack of development of complementary products (such as high speed modems
      and high speed communication lines);

    - implementation of competing technology;

    - delays in the development or adoption of new standards and protocols
      required to handle increased levels of Internet activity; or

    - governmental regulation.

    Moreover, critical issues concerning the use of the Internet remain
unresolved and may affect the growth of the use of such technologies to solve
business problems. If the Internet fails to grow or grows more slowly as a
viable business tool than anticipated, there will be a significant decline in
the need for our services and our revenues will decline.

YEAR 2000 PROBLEMS PRESENT TECHNOLOGICAL RISKS WHICH MAY BE COSTLY TO CORRECT
AND WHICH MAY DISRUPT OUR BUSINESS

    Year 2000 problems could cause us, or our clients, to experience operational
difficulties and incur expenses. Although we have received compliance
information from our material third-party vendors, we have not received
compliance information from all of our third-party vendors. In addition, it is
possible that our third-party vendors were mistaken in certifying that their
systems are Year 2000 compliant. Furthermore, we will not conduct an end-to-end
system test until October 1999. If we fail to fix our internal systems or to fix
or replace material third-party software, hardware or services on a timely
basis, we may suffer lost revenues, increased operating costs and other business
interruptions, any of which would materially and adversely affect us. Moreover,
if we fail to adequately address Year 2000 compliance issues, we may be subject
to claims of mismanagement and related litigation, which would be costly and
time-consuming to defend.

    In addition, we cannot assure you that governmental agencies, utility
companies, Internet access companies, third-party service providers and others
outside our control will be Year 2000 compliant. If those entities fail to be
Year 2000 compliant, there may be a systemic failure beyond our control, such as
a prolonged Internet, telecommunications or electrical failure, which could
materially disrupt our ability to deliver our services.

  RISKS RELATED TO INTELLECTUAL PROPERTY MATTERS AND POTENTIAL LEGAL LIABILITY

UNAUTHORIZED USE OF OUR INTELLECTUAL PROPERTY BY THIRD PARTIES MAY DAMAGE OUR
BRAND

    We regard our copyrights, trade secrets and other intellectual property as
critical to our success. Unauthorized use of our intellectual property by third
parties may damage our brand and our reputation. We rely on trademark and
copyright law, trade secret protection and confidentiality and/or license and
other agreements with our employees, customers, partners and others to protect
our intellectual property rights. However, we do not have any patents or patent
applications pending and existing trade secret, trademark and copyright laws
afford us only limited protection. Despite our

                                       13
<PAGE>
precautions, it may be possible for third parties to obtain and use our
intellectual property without our authorization. The laws of some foreign
countries are also uncertain or do not protect intellectual property rights to
the same extent as do the laws of the United States.

WE MAY NOT BE ABLE TO OBTAIN TRADEMARK PROTECTION FOR SOME OF OUR IMPORTANT
TRADEMARKS, WHICH WOULD SIGNIFICANTLY IMPAIR OUR ABILITY TO PREVENT OTHERS FROM
USING THOSE TRADEMARKS AND MAY REQUIRE US TO REPLACE THEM WITH NEW TRADEMARKS

    The trademark offices in the United States and England have raised
objections to the registration of our "PREDICTIVE SYSTEMS," "BUSINESSFIRST" and
Predictive logo trademarks, including likelihood of confusion with pre-existing
trademarks and descriptiveness. We have responded to these objections and are
awaiting the trademark offices' decisions on our responses. We have not,
however, received any objections from third parties asserting likelihood of
confusion claims with respect to our trademarks. Nonetheless, we may not be able
to obtain trademark registrations in the United States or England, or both, for
one or more of these trademarks, in which case we will be unable to fully
enforce our statutory trademark rights against third parties for these
trademarks, and/or we must decide to replace such trademarks with new
trademarks.

WE MAY HAVE TO DEFEND AGAINST INTELLECTUAL PROPERTY INFRINGEMENT CLAIMS, WHICH
COULD BE EXPENSIVE AND, IF WE ARE NOT SUCCESSFUL, COULD DISRUPT OUR BUSINESS

    We cannot be certain that our services, the finished products that we
deliver or materials provided to us by our clients for use in our finished
products do not or will not infringe valid patents, copyrights, trademarks or
other intellectual property rights held by third parties. As a result, we may be
subject to legal proceedings and claims from time to time relating to the
intellectual property of others in the ordinary course of our business. We may
incur substantial expenses in defending against these third-party infringement
claims, regardless of their merit. Successful infringement claims against us may
result in substantial monetary liability or may materially disrupt the conduct
of our business.

BECAUSE OUR SERVICES ARE OFTEN CRITICAL TO OUR CLIENTS' OPERATIONS, WE MAY BE
SUBJECT TO SIGNIFICANT CLAIMS IF OUR SERVICES DO NOT MEET OUR CLIENTS
EXPECTATIONS

    Many of our projects are critical to the operations of our clients'
businesses. If we cannot complete these projects to our clients' expectations,
we could materially harm our clients' operations. This could damage our
reputation, subject us to increased risk of litigation or result in our having
to provide additional services to a client at no charge. Although we carry
general liability insurance coverage, our insurance may not cover all potential
claims to which we are exposed or may not be adequate to indemnify us for all
liability that may be imposed.

                         RISKS RELATED TO THIS OFFERING

WE DO NOT HAVE A PLAN FOR THE USE OF THE NET PROCEEDS OF THIS OFFERING AND WILL
THEREFORE HAVE DISCRETION AS TO THE USE OF THESE PROCEEDS, WHICH WE MAY NOT USE
EFFECTIVELY

    We have no plan with respect to the use of the net proceeds of this offering
and have not committed these proceeds to any particular purpose. Therefore, our
management will have significant flexibility in applying the net proceeds of
this offering and may use the proceeds in ways with which stockholders disagree.
We may not be able to invest these funds effectively.

OUR STOCK PRICE IS LIKELY TO BE HIGHLY VOLATILE AND COULD DROP UNEXPECTEDLY

    Following this offering, the market price of our common stock is likely to
be highly volatile and may fluctuate substantially. As a result, investors in
our common stock may experience a decrease in the value of their common stock
regardless of our operating performance or prospects. In addition, the

                                       14
<PAGE>
stock market has, from time to time, experienced significant price and volume
fluctuations that have affected the market prices for the securities of
technology companies. In the past, following periods of volatility in the market
price of a particular company's securities, securities class action litigation
was often brought against that company. Many technology-related companies have
been subject to this type of litigation. We may also become involved in this
type of litigation. Litigation is often expensive and diverts management's
attention and resources.

WE ARE CONTROLLED BY A SMALL GROUP OF OUR EXISTING STOCKHOLDERS, WHOSE INTERESTS
MAY DIFFER FROM OTHER STOCKHOLDERS

    Our directors, executive officers and affiliates currently beneficially own
approximately 79.5% of the outstanding shares of our common stock, and after the
offering will beneficially own approximately 67.0% of the outstanding shares of
our common stock. Accordingly, these stockholders will have significant
influence in determining the outcome of any corporate transaction or other
matter submitted to the stockholders for approval, including mergers,
acquisitions, consolidations and the sale of all or substantially all of our
assets, and also the power to prevent or cause a change in control. The
interests of these stockholders may differ from the interests of the other
stockholders.

SHARES ELIGIBLE FOR PUBLIC SALE AFTER THIS OFFERING COULD ADVERSELY AFFECT OUR
STOCK PRICE

    The market price of our common stock could decline as a result of sales by
our existing stockholders of shares of common stock in the market after this
offering, or the perception that these sales could occur. In addition, we have a
significant number of shares that are subject to outstanding options. The
exercise of these options and the subsequent sale of the underlying common stock
could cause a further decline in our stock price. These sales also might make it
difficult for us to sell equity securities in the future at a time and at a
price that we deem appropriate.

OUR CHARTER DOCUMENTS AND DELAWARE LAW MAY INHIBIT A TAKEOVER THAT STOCKHOLDERS
MAY CONSIDER FAVORABLE

    Provisions in our charter and bylaws may have the effect of delaying or
preventing a change of control or changes in our management that stockholders
consider favorable or beneficial. If a change of control or change in management
is delayed or prevented, the market price of our common stock could decline.

YOU WILL SUFFER IMMEDIATE AND SUBSTANTIAL DILUTION

    The initial public offering price per share will significantly exceed the
pro forma net tangible book value per share as of June 30, 1999 of $1.62.
Accordingly, investors purchasing shares in this offering will suffer immediate
and substantial dilution of their investment. In addition, we had 10,293,013
shares subject to options outstanding as of August 31, 1999 at a weighted
average exercise price of $1.87 per share. The exercise of these options will
result in further dilution of the value of the shares purchased in this
offering.

                    FORWARD-LOOKING STATEMENTS; MARKET DATA

    Many statements made in this prospectus under the captions "Prospectus
Summary", "Risk Factors", "Management's Discussion and Analysis of Financial
Condition and Results of Operations," "Business" and elsewhere are
forward-looking statements that are not based on historical facts. Because these
forward looking-statements involve risks and uncertainties, there are important
factors that could cause actual results to differ materially from those
expressed or implied by these forward-looking statements, including those
discussed under "Risk Factors."

    This prospectus contains market data related to our business and the network
consulting and integration services industry. This market data includes
projections that are based on a number of assumptions. If these assumptions turn
out to be incorrect, actual results may differ from the projections based on
these assumptions. As a result, our markets may not grow at the rates projected
by these data, or at all. The failure of these markets to grow at these
projected rates may have a material adverse effect on our business, results of
operations and financial condition, and the market price of our common stock.

    The forward-looking statements made in this prospectus relate only to events
as of the date on which the statements are made. We undertake no obligation to
update any forward-looking statement to reflect events or circumstances after
the date on which the statement is made or to reflect the occurrence of
unanticipated events.

                                USE OF PROCEEDS

    The net proceeds we will receive from the sale of the shares of common stock
offered by us are estimated to be $46.9 million, assuming an initial public
offering price of $13.00 per share, after deducting the underwriting discounts
and commissions and estimated offering expenses payable by us. If the
underwriters' over-allotment option is exercised in full, we estimate that the
net proceeds will be $54.1 million.

    The primary purposes of this offering are to obtain additional equity
capital, create a public market for our common stock, and facilitate future
access to public markets. As of the date of this prospectus, we have not made
any specific expenditure plans with respect to the proceeds of this offering.
Accordingly, our management will have significant flexibility in applying the
net proceeds of this offering. We expect to use the net proceeds of this
offering for general corporate purposes, including working capital. A portion of
the net proceeds may also be used for the acquisition of complementary
businesses or technologies. We are not currently a party to any contracts,
letters of intent, commitments or agreements and are not currently engaged in
active negotiations, with respect to any acquisitions.

    Pending such uses, we will invest the net proceeds of this offering in
investment grade, interest-bearing securities.

                                DIVIDEND POLICY

    We have never declared or paid any cash dividends on our common stock. We
currently intend to retain future earnings, if any, to finance the expansion of
our business. As a result, we do not intend to pay cash dividends in the
foreseeable future.

                                    DILUTION

    Our pro forma net tangible book value as of June 30, 1999 was approximately
$28.3 million, or $1.62 per share of common stock. Pro forma net tangible book
value per share is determined by dividing the amount of our total tangible
assets less total liabilities by the pro forma number of shares of stock
outstanding at that date, assuming the receipt of the net proceeds from the sale
of 1,242,000, 94,867 and 18,133 shares of our common stock to Cisco, General
Atlantic Partners 57 and GAP Coinvestment Partners II, respectively, at
$12.00 per share, the conversion of all outstanding shares of our series A
convertible preferred stock into common stock and the reissuance of our treasury
stock in connection with this conversion. Dilution in net tangible book value
per share represents the difference between the amount per share paid by
purchasers of shares of common stock in this offering and the net tangible book
value per share of common stock immediately after the completion of this
offering.

    After giving effect to the issuance and sale of the shares of common stock
offered by us and after deducting the estimated underwriting discounts and
commissions and offering expenses payable by us, our pro forma net tangible book
value as of June 30, 1999 would have been $75.1 million, or $3.50 per share.
This represents an immediate increase in pro forma net tangible book value of
$1.88 per share to existing stockholders and an immediate dilution of $9.50 per
share to new investors purchasing shares in this offering. If the initial public
offering price is higher or lower, the dilution to the new investors will be
greater or less, respectively. The following table illustrates this per share
dilution.

    This discussion and table assume no exercise of any stock options
outstanding as of June 30, 1999. As of August 31, 1999, there were options
outstanding to purchase a total of 10,293,013 shares of common stock with a
weighted average exercise price of $1.87 per share. To the extent that any of
these options are exercised, there will be further dilution to new investors.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

    THE FOLLOWING DISCUSSION SHOULD BE READ IN CONJUNCTION WITH OUR FINANCIAL
STATEMENTS AND THE NOTES TO THOSE STATEMENTS AND OTHER FINANCIAL INFORMATION
APPEARING ELSEWHERE IN THIS PROSPECTUS.

OVERVIEW

    Substantially all of our revenues are derived from professional services. We
provide network consulting services to our clients on either a project outsource
or collaborative consulting basis. We derive revenues from these services on
both a fixed-price, fixed-time basis and on a time-and-expense basis. We use our
BusinessFirst methodology to estimate and propose prices for our fixed-price
projects. The estimation process accounts for standard billing rates particular
to each project, the client's technology environment, the scope of the project,
and the project's timetable and overall technical complexity. A member of our
senior management team must approve all of our fixed-price proposals. For these
contracts, we recognize revenue using a percentage-of-completion method
primarily based on costs incurred. We make provisions for estimated losses on
uncompleted contracts on a contract-by-contract basis and recognize such
provisions in the period in which the losses are determined. Professional
services revenues for time-and-expense based projects are recognized as services
are performed. Any payments received in advance of services performed are
recorded as deferred revenue. Our clients are generally able to reduce or cancel
their use of our professional services without penalty and with little or no
notice. We also derive limited revenues from the sale of hardware and software.
We sell hardware and software only when specifically requested by a client. We
expect revenues from the sale of hardware and software to continue to decline on
a percentage basis.

    Since we recognize professional services revenues only when our consultants
are engaged on client projects, the utilization of our consultants is important
in determining our operating results. In addition, a substantial majority of our
operating expenses, particularly personnel and related costs, depreciation and
rent, are relatively fixed in advance of any particular quarter. As a result,
any underutilization of our consultants may cause significant variations in our
operating results in any particular quarter and could result in losses for such
quarter. Factors which could cause underutilization include:

    - the reduction in size, delay in commencement, interruption or termination
      of one or more significant projects;

    - the completion during a quarter of one or more significant projects;

    - the miscalculation of resources required to complete new or ongoing
      projects; and

    - the timing and extent of training, weather related shut-downs, vacations
      and holidays.

    Our cost of revenues consist of costs associated with our professional
services and hardware and software purchases. Costs of revenues associated with
professional services include compensation and benefits for our consultants and
project-related travel expenses. Costs of hardware and software purchases
consist of acquisition costs of third-party hardware and software resold.

    On August 12, 1999, we acquired Network Resource Consultants and Company for
an aggregate purchase price of approximately $4.3 million. The purchase price
was paid in the form of 1,062,814 shares of our common stock in exchange for all
of the outstanding capital stock of Network Resource Consultants and Company.
The acquisition was accounted for as a purchase and resulted in intangible
assets of approximately $4.3 million representing the excess purchase price over
the fair value of the net assets acquired. The intangible assets will be
amortized over a period of 5 years.

    On September 16, 1999, we completed the sale of 1,242,000 shares of our
common stock to Cisco at $12.00 per share for net proceeds of approximately
$14.2 million.

                                       22
<PAGE>
    On September 22, 1999, we completed the sale of 94,867 and 18,133 shares of
our common stock to General Atlantic 57, and GAP Coinvestment Partners II,
respectively, at $12.00 per share for net proceeds of approximately $1.4
million.

    We plan to continue to expand our operations by hiring additional
consultants and other employees, and adding new offices, systems and other
infrastructure. The resulting increase in operating expenses will have a
material adverse effect on our operating results if our revenues do not increase
to support such expenses. Based on all of the foregoing, we believe that our
quarterly revenue and operating results are likely to vary significantly in the
future and that period-to-period comparisons of our operating results are not
necessarily meaningful and should not be relied on as indications of future
performance.

RESULTS OF OPERATIONS

    The following table sets forth certain financial data for the periods
indicated expressed as a percentage of total revenues:

SIX MONTHS ENDED JUNE 30, 1998 AND 1999

    REVENUES.  Substantially all of our revenues are derived from fees for
professional services. Revenues increased 138.4% from $9.5 million in the six
months ended June 30, 1998 to $22.6 million in the six months ended June 30,
1999. Revenues from professional services increased 138.1% from $8.9 million in
the six months ended June 30, 1998 to $21.3 million in the six months ended
June 30, 1999. This increase was primarily due to an increase in the number of
professional services projects and an increase in the size of the projects.
Revenues from hardware and software sales increased 142.8% from $530,000 in the
six months ended June 30, 1998 to $1.3 million in the six months ended June 30,
1999. During the six months ended June 30, 1999, each of Bear, Stearns & Co.
Inc. and Qwest Communications, Inc. accounted for 23.1% and 17.1%, respectively,
of our revenues. The number of our billable consultants increased from
approximately 120 at June 30, 1998 to approximately 190 at June 30, 1999.
Subsequent to June 30, 1999, we added an additional 14 billable consultants as a
result of our acquisition of Network Resource Consultants and Company, B.V.

    GROSS PROFIT.  Gross profit increased 193.3% from $3.8 million in the six
months ended June 30, 1998 to $11.3 million in the six months ended June 30,
1999. As a percentage of revenues, gross profit increased from 40.7% in the six
months ended June 30, 1998 to 50.0% in the six months ended June 30, 1999. This
increase in gross profit was due to efficiencies in completing fixed-price,
fixed-time projects, higher utilization rates and an increase in average billing
rates. Cost of revenues increased from $5.6 million in the six months ended
June 30, 1998 to $11.3 million in the six months ended June 30, 1999. This
increase in cost of revenues was due primarily to an increase in compensation
and benefits paid to consultants.

    SALES AND MARKETING EXPENSES.  Sales and marketing expenses consist
primarily of compensation and benefits, travel expenses and promotional
expenses. Sales and marketing expenses increased 171.5% from $1.3 million in the
six months ended June 30, 1998 to $3.4 million in the six months ended June 30,
1999. As a percentage of revenues, sales and marketing expenses increased from
13.3% in the six months ended June 30, 1998 to 15.1% in the six months ended
June 30, 1999. This increase was primarily due to an increase of $1.6 million in
compensation and benefits paid due to the hiring of additional personnel and an
increase of $451,000 in commissions paid.

    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
increased 105.7% from $3.6 million in the six months ended June 30, 1998 to
$7.4 million in the six months ended June 30, 1999. As a percentage of revenues,
general and administrative expense decreased from 37.9% in the six months ended
June 30, 1998 to 32.7% in the six months ended June 30, 1999. The increase in
absolute dollars was primarily due to an increase of $1.9 million in recruiting
and professional development and other administrative costs, an increase of
$1.1 million in compensation and benefits costs, and an increase of $790,000 in
facilities and equipment costs.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased
36.1% from $229,000 in the six months ended June 30, 1998 to $312,000 in the six
months ended June 30, 1999. This increase was due to purchases of additional
equipment to support our growth.

    NONCASH COMPENSATION EXPENSE.  During the six months ended June 30, 1999, we
granted options to purchase shares of common stock at exercises prices that were
less than the fair market value of the underlying shares of common stock. This
will result in noncash compensation expense over the period that these specific
options vest. We estimate the expense will be approximately $48,000 for the year
ended December 31, 1999. During the six months ended June 30, 1999, we recorded
$9,875 of noncash compensation expense related to these options. The remaining
noncash compensation expense beyond 1999 is currently estimated to be $257,000.

    OTHER INCOME (EXPENSE).  Other expense decreased from $54,000 in the six
months ended June 30, 1998 to $2,000 in the six months ended June 30, 1999. This
decrease was primarily due to an increase

                                       24
<PAGE>
in interest expense related to short term borrowings, offset by increased
interest income and other non-operating income.

    INCOME TAXES.  The income tax benefit was ($541,000) on pre-tax losses of
$1.3 million for the six months ended June 30, 1998. For the six months ended
June 30, 1999, the income tax expense was $361,000 on pre-tax income of
$178,000. The effective tax rate was 42.3% and 203.1% during the six months
ended June 30, 1998 and 1999, respectively. The increase in the effective tax
rates relates to the provision for a valuation allowance against net operating
losses of our English subsidiary.

YEARS ENDED DECEMBER 31, 1997 AND 1998

    REVENUES.  Revenues increased 43.3% from $18.1 million in 1997 to
$25.9 million in 1998. Revenues from professional services increased 41.2% from
$16.9 million in 1997 to $23.9 million in 1998. This increase was primarily due
to an increase in the number of professional services projects and an increase
in the size of these projects. Revenues from hardware and software sales
increased 73.6% from $1.2 million in 1997 to $2.1 million in 1998. During 1998,
Bear, Stearns & Co. Inc. accounted for 21.0% of revenues. The number of our
billable consultants increased from approximately 98 at December 31, 1997 to
approximately 149 at December 31, 1998.

    GROSS PROFIT.  Gross profit increased 48.0% from $7.7 million in 1997 to
$11.4 million in 1998. As a percentage of revenues, gross profit increased from
42.5% in 1997 to 43.8% in 1998. This increase in gross profit was due to
efficiencies in completing fixed-price, fixed-time projects, partially offset by
lower utilization rates and a decrease in average billing rates. Cost of
revenues increased from $10.4 million in 1997 to $14.6 million in 1998. This
increase in cost of revenues was due primarily to an increase in compensation
and benefits paid to consultants.

    SALES AND MARKETING EXPENSES.  Sales and marketing expenses increased 217.4%
from $1.1 million in 1997 to $3.4 million in 1998. As a percentage of revenues,
sales and marketing expenses increased from 6.0% in 1997 to 13.2% in 1998. This
increase was primarily due to an increase of $1.6 million in compensation and
benefits paid due to the hiring of additional personnel, an increase of $591,000
due to increased sales and marketing efforts, and an increase of $142,000 in
commissions paid because of the increase in revenues.

    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
increased 86.4% from $4.4 million in 1997 to $8.2 million in 1998. As a
percentage of revenues, general and administrative expense increased from 24.3%
in 1997 to 31.6% in 1998. This increase was due to an increase of $1.4 million
in recruiting and professional development and other administrative costs, an
increase of $1.3 million in compensation and benefits costs, and an increase of
$1.1 million in facilities and equipment costs.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased
76.9% from $321,000 in 1997 to $568,000 in 1998. This increase was due to
purchases of additional equipment to support our growth.

    OTHER INCOME (EXPENSE).  Other expense increased from ($5,000) in 1997 to
($265,000) in 1998. This increase was primarily due to an increase in interest
expense related to an increase in short term borrowings.

    INCOME TAXES.  The income tax provision was $871,000 on pre-tax income of
$1.9 million in 1997. In 1998 the income tax benefit was ($460,000) on pre-tax
losses of $1.1 million. The effective tax rate was 46.3% and 42.3% for 1997 and
1998, respectively. The differences in the effective tax rate resulted from a
greater amount of non-tax deductible expenses during 1997.

YEARS ENDED DECEMBER 31, 1996 AND 1997

    REVENUES.  Revenues increased 123.1% from $8.1 million in 1996 to
$18.1 million in 1997. Revenues from professional services increased 147.8% from
$6.8 million in 1996 to $16.9 million in 1997. Revenues from hardware and
software sales decreased 7.6% from $1.3 million in 1996 to $1.2 million in 1997.
The increase in professional services was primarily due to an increase in the
number of professional services projects and an increase in the size of these
projects. During 1997, each of Bear, Stearns & Co. Inc. and Unisys Corporation
accounted for 20.6% and 19.7% of revenues, respectively. The number of our
billable consultants increased from approximately 42 at December 31, 1996 to
approximately 98 at December 31, 1997.

    GROSS PROFIT.  Gross profit increased 104.6% from $3.8 million in 1996 to
$7.7 million in 1997. As a percentage of revenues, gross profit decreased from
46.3% in 1996 to 42.5% in 1997. The increase in gross profit in absolute dollars
was due to efficiencies in completing fixed-price, fixed-time projects, higher
utilization rates and an increase in average billing rates. Cost of revenues
increased from $4.4 million in 1996 to $10.4 million 1997. This increase in cost
of revenues was due primarily to an increase in compensation and benefits paid
to consultants.

    SALES AND MARKETING EXPENSES.  Sales and marketing expenses increased 180.3%
from $386,000 in 1996 to $1.1 million in 1997. As a percentage of revenues,
sales and marketing expenses increased from 4.8% in 1996 to 6.0% in the 1997.
This increase was due primarily to an increase of $441,000 in compensation and
benefits paid due to the hiring of additional personnel, and an increase of
$126,000 in commissions paid because of the increase in revenues.

    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
increased 160.8% from $1.7 million in 1996 to $4.4 million in 1997. As a
percentage of revenues, general and administrative expense increased from 20.8%
1996 to 24.3% in 1997. This increase was primarily due to an increase of
$1.1 million in facilities and equipment costs, an increase of $883,000 in
recruiting and professional development and other administrative costs, and an
increase of $756,000 in compensation and benefits costs.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased
125.8% from $142,000 in 1996 to $321,000 in 1997. This increase was due to
purchases of additional equipment to support our growth.

    OTHER INCOME (EXPENSE).  Other income (expense) decreased from $39,000 in
1996 to ($5,000) in 1997, due to an increase in interest expense as a result of
short term borrowings during 1997.

    INCOME TAXES.  The income tax provision was $719,000 on pre-tax income of
$1.6 million in 1996. In 1997, the income tax provision was $871,000 on pre-tax
income of $1.9 million. The effective tax rate was 45.4% and 46.3% in 1997 and
1998, respectively. The increase in the effective tax rate above the federal and
state statutory rates reflects certain non-tax deductible expenses.

    We have historically experienced significant quarterly fluctuations in our
revenues and results of operations and expect these fluctuations to continue.
Factors causing these variations include the number, timing, scope and
contractual terms of client projects, delays incurred in the performance of such
projects, accuracy of estimates of resources and time required to complete
ongoing projects, and general economic conditions. In addition, our future
revenues and operating results may fluctuate as a result of changes in pricing
in response to customer demand and competitive pressures, the ratio of
fixed-price contracts versus time-and-expense contracts and the timing of
collection of accounts receivable. A high percentage of our operating expenses,
particularly personnel and rent, are relatively fixed in advance of any
particular quarter. As a result, unanticipated variations in the number and
timing of our projects or in employee utilization rates may cause significant
variations in operating results in any particular quarter, and could result in
losses. Any significant shortfall of revenues in relation to our expectations,
any material reduction in utilization rates for our consultants, an
unanticipated termination of a major project, a client's decision not to pursue
a new project or proceed to succeeding stages of a current project, or the
completion during a quarter of several major customer projects could require us
to pay underutilized employees and have a material adverse effect on our
business, results of operations and financial condition.

    Our quarterly operating results are also subject to certain seasonal
fluctuations. We have in the past recruited new consultants in the first and
second quarters who have not conducted billable services until later in the
year. Demand for our services may be lower in the fourth quarter due to reduced
activity during the holiday season and fewer working days for those customers
that curtail operations during this period. These and other seasonal factors may
contribute to fluctuations in our operating results from quarter to quarter.

LIQUIDITY AND CAPITAL RESOURCES

    Since inception, we have financed our operations through the sale of equity
securities and cash flow from operations. As of June 30, 1999, we had
approximately $360,000 in cash and cash equivalents.

    Cash used in operating activities increased from $960,000 for the six months
ended June 30, 1998 to $4.4 million for the six months ended June 30, 1999.
Significant uses of cash resulted from an increase in accounts receivable,
unbilled work in progress and a decrease in deferred income, partially offset by
a reduction in the net loss.

    Cash (used in) provided by operating activities was ($3.7) million in 1998,
($1.2) million in 1997 and $678,000 in 1996. The increase in the use of cash
resulted from the net loss in 1998, an increase in accounts receivable and
unbilled work in progress during 1998 partially offset by an increase in
accounts payable and accrued expenses at December 31, 1998.

    Cash provided by financing activities was $12.5 million for the six months
ended June 30, 1999, $5.4 million for 1998, $1.4 million for 1997 and $5,000 for
1996. Cash provided by financing activities for the six months ended June 30,
1999 resulted from the proceeds of $18.6 million related to the sale of
preferred stock offset partially by the repayment of short-term borrowings. Cash
provided by financing activities for 1998 and 1997 resulted from short-term
borrowings.

    Our capital expenditures were $745,000 for the six months ended June 30,
1999, $687,000 for 1998, $357,000 for 1997 and $315,000 for 1996. Capital
expenditures were made to purchase computer equipment and office furniture and
for leasehold improvements.

    We have a demand loan facility, secured by a lien on all of our assets,
under which we may borrow up to the lesser of $5.0 million or 80.0% of our
accounts receivable. Amounts outstanding under the facility bear interest at a
rate of 11.25% per annum. At June 30, 1999, there were no amounts outstanding
under the facility.

    On September 16, 1999, we completed sale of 1,242,000 shares of our common
stock to Cisco at $12.00 per share for net proceeds of approximately $14.2
million.

                                       28
<PAGE>
    On September 22, 1999, we completed the sale of 94,867 and 18,133 shares of
our common stock to General Atlantic Partners 57 and GAP Coinvestment Partners
II, respectively, at $12.00 per share for net proceeds of approximately $1.4
million.


    We believe that our current cash and cash equivalents, together with cash
generated from operations, will be sufficient to meet our foreseeable working
capital needs for at least the next 12 months.


IMPACT OF THE YEAR 2000 COMPLIANCE

    Many currently installed computer systems and software products are coded to
accept or recognize only two-digit entries in the date code field. These systems
may recognize a date using "00" as the year 1900 rather than the year 2000. As a
result, it is necessary to update the computer systems and/or software used by
many companies and governmental agencies to comply with Year 2000 requirements
or risk system failure or miscalculations causing disruptions of normal business
activities.

    We are exposed to the risk that the systems on which we depend to conduct
our operations are not Year 2000 compliant.

    STATE OF READINESS.  We are in the process of determining the Year 2000
readiness of our information technology systems, which include our hardware and
software, and our non-information technology systems, which include the
telephone systems and other office equipment we use internally. Our assessment
plan consists of the following steps:

    - evaluating our date dependent code, software and hardware and evaluating
      external dependencies;

    - quality assurance testing of our internally-developed proprietary
      software;

    - contacting third-party vendors and licensors of material hardware,
      software and services that we use;

    - contacting vendors of material non-information technology systems that we
      use;

    - formulating repair or replacement requirements and implementing corrective
      measures; and

    - evaluating the need for, and preparing and implementing, if required, a
      contingency plan.

    To date, we have determined the following through our assessment:

    - We have checked our internally developed software and systems for date
      dependent code, and all material files and systems are Year 2000
      compliant. We believe that the recently installed code is also Year 2000
      compliant;

    - We have contacted the vendors of material hardware and software components
      of our information technology systems, and they have informed us that the
      products we use are currently Year 2000 compliant;

    - Commercial software, including financial reporting software, upon which we
      depend is either Year 2000 compliant or will be upgraded to be compliant
      in the normal course of business through upgrades or installation of
      software patches;

    - Substantially all hardware we use in our network operations and all of the
      hardware we use in our office operations have been certified as Year 2000
      compliant by its vendors;

    - Our telephone system and mail systems are certified as Year 2000
      compliant; and

    - Our landlords and third-party advertising sales representative and
      servicing organizations have not yet provided us with Year 2000 compliance
      information.


    While we have assessed the Year 2000 readiness of each of our material
internal systems, we will not conduct an end-to-end system test until October
1999. Accordingly, we cannot yet assess whether our internal system, as a whole,
is Year 2000 compliant. In addition, we will continue to attempt to obtain
verification from all remaining distributors, suppliers and vendors that their
systems are Year


                                       29
<PAGE>

2000 compliant. We intend to complete our assessment, and the replacement or
remediation of any non-Year 2000 compliant technologies, by the end of the third
quarter of 1999.


    COSTS.  We estimate that the total cost for our Year 2000 compliance efforts
will be approximately $250,000. Most of these expenses relate to the operating
costs associated with time spent by our employees in Year 2000 compliance
matters. If we encounter unexpected difficulties, or we are unable to obtain
compliance information from material third parties, we may need to spend
additional amounts to ensure that our systems are Year 2000 compliant.

    RISKS.  Although we have received compliance information from our material
third-party vendors, we have not received compliance information from all of our
third-party vendors. In addition, it is possible that our third-party vendors
were mistaken in certifying that their systems are Year 2000 compliant. In
addition, we will not conduct an end-to-end system test until October 1999. If
we fail to fix our internal systems or to fix or replace material third-party
software, hardware or services on a timely basis, we may suffer lost revenues,
increased operating costs and other business interruptions, any of which could
have a material adverse effect on our business, results of operations and
financial condition. Moreover, if we fail to adequately address Year 2000
compliance issues, we may be subject to claims of mismanagement and related
litigation, which would be costly and time-consuming to defend.

    In addition, we cannot assure you that governmental agencies, utility
companies, Internet access companies, third-party service providers and others
outside our control will be Year 2000 compliant. If those entities fail to be
Year 2000 compliant, there may be a systemic failure beyond our control, such as
a prolonged Internet, telecommunications or electrical failure, which could have
a material adverse effect on our business, results of operations and financial
condition.

    CONTINGENCY PLAN.  As discussed above, we are engaged in an ongoing Year
2000 assessment and have developed no contingency plans to address the
worst-case scenario that might occur if technologies we depend upon actually are
not Year 2000 compliant. We will take into account our Year 2000 simulation
testing results and the responses we receive from all third-party vendors and
service providers in determining the need for and nature and extent of any
contingency plans. We intend to develop any required contingency plan by the end
of October 1999.

FORWARD-LOOKING STATEMENTS

    The Year 2000 discussion above is provided as a "Year 2000 Readiness
Disclosure" as defined in the Year 2000 Information and Readiness Disclosure Act
of 1998 (Public Law 105-271, 112 Stat. 2386) enacted on October 19, 1998 and
contains forward-looking statements. These statements are based on management's
best current estimates, which were derived from a number of assumptions about
future events, including the continued availability of resources,
representations received form third parties and other factors. However, we
cannot assure you that these estimates will be achieved, and our actual results
could differ materially from those anticipated. Specific factors that might
cause material differences include:

    - the ability to identify and remediate all relevant systems;

    - results of Year 2000 testing;

    - adequate resolution of Year 2000 issues by governmental agencies,
      businesses and other third parties who are our outsourcing service
      providers, suppliers, and vendors;

    - unanticipated system costs; and

    - our ability to implement adequate contingency plans.

RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1997, the Financial Accounting Standard Board, or FASB, issued
Statement of Financial Accounting Standards, or SFAS No. 131, "Disclosures About
Segments of an Enterprise and Related Information." This statement establishes
standards for the way public business enterprises report

                                       30
<PAGE>
information about operating segments in annual financial statements and requires
that those enterprises report selected information about operating segments in
interim financial reports issued to shareholders. This statement is effective
for financial statements for periods beginning after December 15, 1997 and need
not be applied to interim periods in the initial year of application.
Comparative information for earlier years presented is to be restated. We do not
operate in more than one segment. Our chief operating decision maker allocates
resources and assesses the performance associated with its business on a
single-segment basis.

    In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivatives and
Hedging Activities." This statement establishes accounting and reporting
standards of derivative instruments, including certain derivative instruments
embedded in other contracts, and for hedging activities. This statement is
effective for all quarters of fiscal years beginning after June 15, 1999. We do
not expect the adoption of this standard to have a material effect on our
results of operations, financial position or cash flows.

                                    BUSINESS

OVERVIEW

    We are a network consulting company focused on the design, performance,
management and security of complex computing networks. We utilize our
proprietary consulting methodology, BusinessFirst, to translate our clients'
strategic business objectives into sound technology solutions. Using our
BusinessFirst methodology, we demonstrate the business value of technology
solutions in specific and measurable terms, thereby enabling our clients to
incorporate objective and quantifiable analysis into their technology investment
decisions.

    As an independent service provider, we provide our clients with unbiased
expertise that enable the design, implementation and management of optimal
technology solutions. We provide our services on either a project outsource or
collaborative consulting basis. Our project outsource services are based on and
measured against mutually agreed upon service offerings and provide our clients
with certainty of costs, delivery time and project scope. Our collaborative
consulting services enable our clients to utilize our extensive expertise in
order to extend their internal capabilities and to access our methodologies. In
addition to these services, we have developed an innovative service model
through which we deliver our clients packaged service products, otherwise
referred to as productized services. Our service products are characterized by
pre-defined service offerings that have pre-defined deliverables, a pre-defined
pricing model and are implemented using a pre-defined methodology. In contrast
to our project outsource and collaborative consulting services which provide our
clients with services that are customized for, and therefore unique to, each
engagement, our service products are typically provided with little or no
modification.

    Our consultants are organized into the following practice areas, which cover
the four cornerstones of network computing: network and systems management;
internetwork design and engineering; performance management; and information
security. This structure enables our consultants to gain in-depth expertise and
become intimately familiar with the best practices and methodologies identified
within each of those disciplines.

INDUSTRY BACKGROUND

    The effective communication and management of information has become
critical to success in today's competitive and rapidly changing global business
environment. Network infrastructures that once were viewed as sources of
competitive advantage are now being recognized as competitive necessities for
businesses in a broad range of industries. This shift is driven primarily by the
following factors:

    - the migration from mainframe and client/server technologies to
      Internet-based computing environments among most industries;

    - the demand for real-time exchange of critical, time-sensitive information
      within organizations and among their external constituents; and

    - the widespread adoption of the Internet among consumers.

    As a result of these factors, current and emerging network hardware and
software companies are rapidly developing sophisticated technologies for
business users to accommodate critical applications, such as electronic
commerce, supply chain management, web hosting, customer relationship management
and global marketing. In addition to business use of networks, consumers are
increasingly accessing networks, via the Internet, to communicate, store and
publish information, conduct retail transactions and access online sources of
entertainment. Business and consumer trends will continue to positively impact
the number of users who access, and the data traffic carried over, the Internet.

                                       32
<PAGE>
    The growth in network-dependent activities requires complex network
solutions that integrate a variety of systems and technologies from multiple
vendors. The rapid pace of change in networking technology has further increased
the complexity of designing and implementing these network solutions. As
competing hardware and software companies develop applications to more
effectively and efficiently manage increasing volumes of information, rapid
adoption of new technologies is required for businesses to remain competitive.
Accordingly, the demand for experienced professionals that can assist businesses
in designing, implementing, managing and monitoring complex network solutions
has increased dramatically.

    As a result of demand for professionals with networking expertise, it has
become increasingly difficult for businesses to attract and retain dedicated
internal information technology resources. In response, many businesses are
focusing on their core competencies and outsourcing their network management
needs to third-party service providers. Consequently, the demand for network
consulting and integration services has grown dramatically. International Data
Corporation, a market research organization, estimates that the worldwide market
for these services will grow from $12.1 billion in 1998 to $25.5 billion by
2003. There are many third-party service providers, including network equipment
vendors, systems integrators, value-added resellers and network consulting
companies, seeking to capitalize on this growth.

    However, we believe that few have the requisite focus and expertise to
address the complex, multi-faceted issues surrounding today's networks, and many
are limited by the fact that they:

    - are primarily motivated by distributing their own products and often lack
      the skills to implement multi-vendor solutions;

    - are focused on traditional mainframe computing environments and derive a
      large percentage of their revenue from reselling hardware and software
      products; or

    - only augment businesses' in-house capabilities with hourly rate-based
      teams of technical personnel.

    As a result, a significant opportunity exists for a service provider that
can offer businesses high-end consulting and technical expertise in the design,
implementation, management and security of complex networks.

THE PREDICTIVE SOLUTION

    We are a network consulting company focused on the design, performance,
management and security of complex computing networks. We utilize our
proprietary consulting methodology, BusinessFirst, to translate our clients'
strategic business objectives into sound technology solutions. We believe that
our success to date has been largely attributable to the following key
characteristics of our service offerings:

    QUANTIFIABLE BUSINESS ANALYSIS.  Using our BusinessFirst methodology, we can
demonstrate the business value of technology solutions in specific and
measurable terms, thereby enabling our clients to incorporate objective and
quantifiable analysis into their technology investment decisions. We utilize
widely accepted principles of risk analysis and mitigation used by the insurance
and financial services industries to assess our client's technology environment.
We provide our clients with a detailed analysis of the financial benefit of a
project by quantifying factors such as business risks, total cost of ownership
and operational efficiency. As a result, our clients can gain a clear
understanding of the benefits that they will derive from their network
technology investments and a measure of certainty about how their technology
investments will be translated into quantifiable improvements to their business
processes.

    FLEXIBLE AND INNOVATIVE SERVICE DELIVERY METHODOLOGIES.  We provide our
clients with a flexible service delivery model that is designed to enhance their
ability to cost-effectively leverage our expertise.

                                       33
<PAGE>
We are engaged by our clients in one of three ways: on a project outsource
basis, on a collaborative consulting basis or through the purchase of
pre-defined service offerings, otherwise known as service products. When engaged
on a project outsource basis, we work with our clients to mutually define a
fixed scope of work at the beginning of the project that is tailored to the
clients' specific needs and therefore, modified from engagement to engagement.
We then deliver the services for a fixed fee, in a fixed period of time with a
fixed set of deliverables. When engaged on a collaborative consulting basis, we
extend our clients' internal technical capabilities with our consultants. This
enables our clients to utilize our extensive expertise and to access our
methodologies while they retain overall responsibility for the project.
Collaborative consulting services are typically billed on a time and expense
basis, and typically do not entail fixed-cost, fixed-time or fixed-service
commitments. Our service products are pre-defined service offerings that we
believe address the needs that are common to many of our clients. These service
products are characterized by pre-defined deliverables, pre-defined pricing and
are provided with little or no modification.

    IN-DEPTH NETWORK COMPUTING EXPERTISE.  Our consultants are organized into
practice areas which cover the four cornerstones of network computing: network
and systems management; internetwork design and engineering; performance
management; and information security. This enables our consultants to gain
in-depth expertise and become intimately familiar with the best practices within
each of those disciplines. More importantly, it enables us to leverage the
knowledge base within each practice group to provide our clients with
cross-functional teams of consultants that are better equipped to address their
varying networking needs in a coordinated and efficient manner.

STRATEGY

    Our goal is to become the leading provider of services for the design,
performance, management and security of complex networks. To achieve this goal,
we intend to pursue the following strategies:

    CONTINUE TO EVOLVE OUR BUSINESSFIRST METHODOLOGY.  The evolution and
enhancement of our BusinessFirst methodology is critical to our ability to
leverage and share knowledge across engagements and to further improve our
ability to deliver predictable, high-quality services to our clients on time and
on budget. We have a dedicated team of consultants that is focused on
continuously enhancing and refining our BusinessFirst methodology by
incorporating the best practices identified over numerous engagements. We
believe that this enables us to consistently deliver high-quality network
technology solutions.

    EXPAND AND ENHANCE OUR SERVICE PRODUCT OFFERINGS.  We intend to continue to
enhance and expand our innovative service product offerings. These service
offerings provide our clients with a pre-defined set of deliverables that
require minimal customization and are characterized by an objective and
quantifiable value proposition and return on investment justification. Moreover,
our service products enable us to increase our margin opportunities by improving
the efficiency of our sales and service delivery model. These products also
enable us to market and sell our services through indirect channels. For
example, we recently entered into an agreement with Cabletron under which
Cabletron has agreed to market and sell our service product offerings, which
will initially include our Information Security Requirements Analysis product
and will expand to other service product offerings. We intend to enter into
other strategic relationships which will enable us to further expand our market
penetration by leveraging our strategic partners' distribution channels to
market and sell these services.

    CONTINUE TO ATTRACT AND RETAIN HIGHLY QUALIFIED CONSULTANTS.  We intend to
continue to attract and retain highly qualified consultants by providing them
with a rich environment and culture to work in, and by offering them attractive
professional development and compensation opportunities. We generally recruit
consultants who have significant technical expertise and offer them the ability
to accelerate their career development by working with sophisticated
technologies in complex, multi-vendor environments. We have established a formal
training program, Predictive University, which is designed to improve the

                                       34
<PAGE>
skills and productivity of our consultants. We intend to continue to build our
nationwide recruiting organization, promote our corporate culture with stated
values, and to invest heavily in the training and development of our
consultants.

    FURTHER INCREASE OUR INDUSTRY EXPERTISE.  We intend to continue to expand
the scope of our industry expertise in order to further penetrate the markets
which we serve. We believe our expertise in specific industries considerably
enhances our ability to help companies within those industries gain competitive
advantage by improving the performance and utility of their networks. We have
significant experience within the financial services, communication services,
and Internet and electronic commerce industries. In each of these markets, we
employ industry experts, pursue targeted sales and marketing opportunities and
develop industry-specific service offerings. We intend to expand into other
industries which we believe will be well suited to our services.

    EXPAND IN EXISTING AND NEW GEOGRAPHIC MARKETS.  We intend to expand our
presence in the geographic markets we currently serve and to enter new markets.
We believe that building a critical mass of highly-qualified consultants and
establishing a multi-national presence through both internal growth and
acquisitions will provide us with a substantial competitive advantage. We
recently acquired Network Resource Consultants and Company B.V. in The
Netherlands in order to further expand our European presence. We currently offer
our services through a network of nine offices located throughout the United
States and in London, England and Amsterdam, The Netherlands. We intend to
continue to pursue strategic acquisitions to gain access to new geographic
markets, additional talented professionals, and network management tools and
methodologies.

BUSINESSFIRST METHODOLOGY

    BusinessFirst is a proprietary methodology that governs our organization and
client engagements. Our BusinessFirst methodology enables us to better
understand the business objectives that drive the need for technology solutions
and provide our clients with pre-defined services on a fixed-time, fixed-price
basis. We begin each engagement by helping our clients clarify their business
requirements in specific terms. We then undertake a thorough assessment of our
client's existing business processes and technology infrastructure. Based on
this assessment, we formulate an analysis of the requirements to translate their
technology investments into measurable business objectives. Once we formulate a
requirements analysis, we draw upon our broad expertise to design a solution
that leverages our clients' existing technology infrastructure to maximize their
return on investment. We believe that our BusinessFirst methodology bridges the
gap in the marketplace between management consulting firms and technical staff
augmentation services and enables us to translate business objectives into
leading-edge technology solutions.

SERVICES

    Our consultants are organized into four practice areas. Although many of our
consultants are cross-skilled in a variety of technologies and many technologies
span multiple practice areas, each practice area represents an aspect of network
technology important enough to warrant specialization.

    These practice areas are:

    - network and systems management;

    - internetwork design and engineering;

    - performance management; and

    - information security.

    Our consultants have extensive experience with a wide variety of
technologies and vendors. For some clients, our consultants are involved in both
technology and vendor selection. Other clients have

                                       35
<PAGE>
already selected the technology, vendor or both. Regardless, we offer our
clients a completely objective, vendor-neutral approach. Our knowledge of
advanced technologies and leading vendors is a significant part of our value
proposition to our clients.

    NETWORK AND SYSTEMS MANAGEMENT.  Our network and systems management practice
focuses on designing and implementing reliable and continuously available
management systems for large-scale, highly-complex networks. The fundamental
tenet of this practice area is that proactive management is an essential element
of any network design and engineering effort. Our network management consultants
develop systems and processes that are able to identify, isolate and resolve
network failures, sometimes before they occur.

    The following table lists some of the services provided by our network and
systems management practice area:

Network Baselining                          Collects data in order to establish a baseline of
                                            network resource utilization. The baseline is then
                                            used as a comparison against future trends.

Application Impact Analysis                 Analyzes how an application uses network resource to
                                            predict response times that users will experience when
                                            the application is deployed. Recommends improvements
                                            that enable the application to maximize network
                                            resources.

Network Usage-Based Billing Services        Assists clients' transition from a flat-rate billing
                                            model to a usage-based billing model for buying
                                            network services.

Capacity Planning                           Assists clients in understanding the capacity and
                                            network resource constraints that exist within their
                                            network with sufficient advance warning to enable them
                                            to add capacity before user performance is affected.

Response Time Management                    Monitors and analyzes end-user application response
                                            times to ensure that they remain within the service
                                            level commitments.

Network Simulation Modeling                 Models a network environment so that new configuration
                                            and new application deployment scenarios can be
                                            simulated before going into production.

ensuring that the confidentiality, integrity and availability of our clients'
networks are protected. Our information security consultants have practical
experience with a wide array of advanced security technologies, as well as the
social and procedural aspects of security. By translating the complexities of
information security into understandable terms such as risks, costs and
benefits, we enable our clients to make clear and informed decisions about
protecting their information assets.

SERVICE PRODUCTS

    Through our collective experience, we gain insights into the common needs of
our clients. When we determine that a need is both urgent and pervasive, we
standardize our services into a solution referred to as a service product. Our
service products are pre-defined service offerings that are replicable from one
project to another and have a pre-defined set of service deliverables, a
pre-defined pricing model and are implemented using a pre-defined methodology.
In contrast to our project outsource and collaborative consulting services which
provide our clients with services that are customized for, and therefore unique
to, each engagement, our service products are typically provided with little or
no modification.

    Our service products offer a number of advantages as compared to custom
consulting engagements. These include:

    - efficient delivery of our services over and over again using a replicable
      methodology;

                                       39
<PAGE>
    - ability to gain broad market penetration because our productized services
      are well-defined and can be more easily sold by our sales force and
      through third-party sales channels;

    - ability to more effectively articulate the business benefit of our
      services based on observing the impact that our service products have for
      other clients; and

    - a more flexible pricing strategy that is based on the business benefit to
      our clients and not the cost to deliver our services.

Our current service products include:

    INFORMATION SECURITY REQUIREMENTS ANALYSIS.  This service product is
designed to discover information security weaknesses in our clients' networks
and systems. It provides our clients with the ability to understand where they
are vulnerable to a security threat and both the likelihood and potential cost
of each threat. Our certified security experts assess a client's physical,
administrative and technical security. They then present a report to management
explaining how the security weaknesses that they have found could impact the
client's business and propose strategies for addressing these weaknesses.

    NETWORK ASSESSMENT.  This service product provides a cost-effective expert
analysis of a client's existing network environment. It provides a report that
helps the client to understand the performance and reliability characteristics
of its network and provides specific recommendations for improvements to the
network along with an analysis of the business benefits that can be achieved
through the recommended improvements.

    APPLICATION IMPACT STUDY.  This service product provides clients with the
information they need to understand how the deployment of a new application will
impact an existing network. Our consultants use a combination of sophisticated
analysis tools and methodologies to thoroughly understand how an application
uses network resources. They then issue a report on the application's
performance and its impact on the client's network. Clients can then determine
if they need to enhance their network in order to ensure that their critical
applications perform to their requirements.

    NETWORK BILLING.  This service product provides clients with a detailed
breakdown of who, how, why, when and where their network was used by their
employees so they can charge employees based on their actual network usage. Our
consultants implement the technology to collect the network usage statistics,
and advise our clients on the most appropriate pricing strategy to charge for
network usage. We then produce the bills that are passed on to the network
users.

    ENTERPRISE MANAGEMENT ASSESSMENT.  This service product provides an
evaluation of a client's current enterprise network management systems. Our
consultants analyze both a client's enterprise network management technology and
its service level agreements. They then provide the client with a tactical and
strategic roadmap that enables the client to implement network management
solutions that support the client's business objectives.

    NETWORK MODELING.  This service product allows clients to ask "what if"
questions about planned changes in their network before the changes are
implemented. Using a combination of sophisticated software tools and our own
methodology, we build a model of the network environment. We can then simulate
changes in the environment such as adding applications or changing equipment,
and observe the impact. Clients can then use this analysis to optimally plan
changes in their network.

    YEAR 2000 COMPLIANCE ASSESSMENT.  This service product identifies network
infrastructure that is at risk because of Year 2000 problems and the impact
these risks can have on a client's business. Our network systems engineers
analyze a client's network infrastructure devices and enterprise management
applications to determine the potential risk based on vendor specifications.
They then develop a plan for remediation to minimize the Year 2000 risk to a
client's business.

REPRESENTATIVE CLIENT CASE STUDIES



    The following case studies are representative of some of the network
consulting services that we have provided to our clients.


    UUNET.  UUNET, the Internet services division of MCI WorldCom, is a global
leader in Internet communications solutions to businesses worldwide. UUNET has
built its reputation on providing high-quality services such as Internet access,
web hosting, remote access and other value-added networking services. To ensure
its ability to provide clients with the highest levels of service, UUNET
constructed one of the most rigorously-engineered and widely deployed
Internet-protocol networks in the world. UUNET currently offers service to more
that 70,000 businesses in 114 countries throughout North America, Europe and
Asia Pacific. UUNET selected us to develop its next-generation Internet-based
service offering, Virtual Private Networking.

    Virtual Private Networks, or VPN's, provide secure, encrypted connections
over the public Internet that allow businesses to communicate privately without
having to build separate private networks. While UUNET's own network systems
engineers are among the most experienced in the world, they wanted an
independent assessment of their VPN system design. We worked with UUNET to
develop a comprehensive VPN solution, including network management, service
provisioning and fulfillment, and network security. We also worked successfully
with UUNET to ensure that the VPN was scalable across UUNET's global network,
both in terms of functionality, ease of deployment and ease of operation.
Finally, we helped develop and document the processes and procedures necessary
to efficiently operate the service.

    The success of UUNET's VPN service has led to other collaborations with us,
including the development of UUNET's Internet-based fax service and branded
dial-up Internet access service.


    BT SYNCORDIA SOLUTIONS.  BT Syncordia Solutions, a division of British
Telecom, is Europe's second largest provider of managed and outsourced network
solutions. BT Syncordia manages the infrastructure of more than 27,000 clients
in 46 countries. BT Syncordia-managed networks carry a significant portion of
the commercial banking transactions in the United Kingdom. In order to meet


                                       41
<PAGE>

the availability requirements of its customers, BT Syncordia turned to us to
help it design and build a world-class network operations center.



    We used our Business First methodology and extensive technical experience to
design and build a network operations center for BT Syncordia. We integrated
sophisticated network management tools that could manage BT Syncordia's
multi-vendor network and easily incorporate changes due to increases in network
traffic, introduction of new services and increases in customer base. We also
instituted processes and procedures that enabled BT Syncordia's operations staff
to act rapidly to identify and resolve network performance issues.


    UNION BANK OF CALIFORNIA.  Union Bank of California has been a leader in the
development of on-line banking products and services. Its early entree into the
on-line banking arena has allowed it to effectively utilize the Internet to
conduct a significant amount of banking transactions each day. Critical to the
continued success and growth of Union Bank of California's on-line presence is
the security of its networks. Union Bank has turned to us to address its network
security requirements.

    Even though Union Bank of California had designed and implemented
sophisticated security technology solutions, they enlisted our help to validate
its security program and to assist it in highlighting deficiencies or
vulnerabilities in its existing security program. We performed a thorough
assessment of their perimeter defenses, encryption strategy, authentication
techniques, and operational processes and procedures. Our efforts helped Union
Bank of California make necessary changes to their infrastructure, security
systems and operational policies that significantly improved the security of
their Internet banking and other on-line initiatives. We also created an ongoing
review process to ensure continued, optimal security.

SALES AND MARKETING

    We have developed direct and indirect sales channels for the sale of our
services. To facilitate our direct sales effort we have developed the
infrastructure necessary to capture and track the major sales indicators through
the sales cycle. Additionally, a significant amount of time and effort has been
and will continue to be invested in the development of tools, training materials
and training for sales and technical personnel. Our service products have
provided us with an opportunity to develop strategic third-party relationships
with hardware, software service and telecommunications providers in order to
expand our sales channel. As a result, we are developing an indirect sales
channel through relationships with third-party strategic partners. We have
entered into an agreement with Cabletron under which Cabletron has agreed to
market and sell our service products. Cabletron will initially sell and market
our Information Security Requirements Analysis product, with an additional 3
products to be added over the term of the agreement. The products will be sold
by Cabletron. We will provide the services for each product for which we will be
paid a predetermined amount by Cabletron. The term of the agreement is through
July 30, 2001 and will renew automatically for successive one year terms unless
terminated by either of us. We intend to pursue similar agreements with other
strategic partners in order to broaden our indirect sales channel.

HUMAN RESOURCES

    We seek to attract, train, retain and deliver the highest level of technical
talent. We believe that our proactive approach gives us a strong competitive
edge in the marketplace and a scalable, consistently high standard of service
delivery. As of August 31, 1999, we had 349 full-time employees.

    RECRUITING.  Our success is dependent in part on attracting and retaining
talented and motivated personnel at all levels. Accordingly, we invest
significant resources in our recruiting efforts. We have a proactive recruiting
philosophy and believe in a broad-based model for attracting candidates.
Generally, we hire technical consultants according to profiles that fit into one
of our four practice areas.

                                       42
<PAGE>
    CORPORATE CULTURE.  Our corporate culture is shaped by our view of employees
as investors because they choose to invest their talents, skills, time and
energy into our organization. This mindset is critical to our ability to attract
and retain professional staff at a time when information technology
professionals are in high demand. We have instituted a very competitive benefits
package for all employees and have developed policies that ensure that we
continue to address our employees' professional development and satisfaction. We
strive to maintain our relaxed and supportive workplace despite our rapid growth
and expansion.

    PROFESSIONAL DEVELOPMENT.  We believe that our investment in our employees
must mirror our employees' investment in and commitment to us. Integral to this
goal is the establishment of a career development plan for each of our
employees, which is created and agreed upon by management and the employee. We
provide our consultants with the opportunity to obtain extensive subject matter
expertise in their practice area and to work in collaborative multi-discipline
projects. We have also established Predictive University, a training program
that leverages both our in-house captured knowledge programs, as well as
selected outside certification programs.

    COMPENSATION.  We believe that linking employee compensation to our success
through performance-based incentive programs encourages a high level of
involvement from each team member and increases our employee retention. We
provide a highly competitive compensation package that consists of a combination
of base salary, performance-based incentives and company stock options.

COMPETITION

    The network management consulting industry is comprised of many
participants, is highly competitive and is subject to rapid technological
change. We face intense competition from systems integrators, value added
resellers, local and regional network services firms, telecommunications
providers, network equipment and computer systems vendors. Many of our
competitors have greater name recognition, longer operating histories, more
relationships with large and established clients and greater financial,
technical and managerial resources. Furthermore, we expect that our competitors
may in the future form alliances with other technology vendors, which may give
them an advantage in managing networks that use that vendor's equipment.

    Most of our current clients and prospective clients have internal
information technology departments and could choose to satisfy their network
management needs through internal resources rather than by outsourcing them to
third-party service providers such as ourselves. The decision by clients or
prospective clients to rely on their own information technology departments
could have a material adverse affect on our business, results of operations and
financial condition. Moreover, as the domestic and global markets for
information technology services continue to grow, we expect to face stiff
competition from new entrants into the network management consulting industry.

    We believe that the principal competitive factors in the network management
market are the ability to attract and retain qualified personnel, quality and
breadth of services offered, price and reliability of services provided and the
strength of client relationships. We believe we compete favorably with respect
to all of these factors. We believe we distinguish ourselves from our
competitors through our expertise in managing complex, multi-vendor networks and
our ability to provide clients with cost certainty and guaranteed deliverables.

INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS

    We regard our copyrights, trade secrets and other intellectual property as
critical to our success. Unauthorized use of our intellectual property by third
parties may damage our brand and our reputation. We rely on trademark and
copyright law, trade secret protection and confidentiality and/or license and
other agreements with our employees, customers, partners and others to protect
our intellectual property rights. Despite our precautions, it may be possible
for third parties to obtain and use our intellectual property without our
authorization. Furthermore, the validity, enforceability and

                                       43
<PAGE>
scope of protection of intellectual property in Internet-related industries is
uncertain and still evolving. The laws of some foreign countries do not protect
intellectual property to the same extent as do the laws of the United States.

    We pursue the registration of our trademarks in the United States and
England. We may not be able to secure adequate protection of our trademarks in
the United States and other countries. We currently have applied for trademark
registrations in the United States and England for the PREDICTIVE SYSTEMS and
BUSINESSFIRST marks, and further, a trademark application in the United States
for the Predictive logo. The trademark offices in the United States and England
have raised preliminary objections to the registration of the trademarks
described above on a number of grounds, including likelihood of confusion with
pre-existing trademarks and descriptiveness. We have responded to these
objections and are awaiting the trademark offices' decisions on our responses.
We have not, however, received any objections from third parties asserting
likelihood of confusion claims with respect to our trademarks. Nonetheless, we
may not be able to obtain trademark registrations in the United States or
England, or both, for one or more of these trademarks, in which case we would be
unable to fully enforce our statutory trademark rights against third parties for
these trademarks, and/or we may decide to replace these trademarks with new
trademarks. This could have a material adverse effect on our business, financial
condition and results of operations. Effective trademark protection may not be
available in all the countries in which we conduct business. Policing
unauthorized use of our marks is also difficult and expensive. In addition, it
is possible that our competitors have adopted or will adopt product or service
names similar to ours, thereby impeding our ability to build brand identity and
possibly leading to customer confusion.

    We cannot be certain that our services and the finished products that we
deliver do not or will not infringe valid patents, copyrights, trademarks or
other intellectual property rights held by third parties. We may be subject to
legal proceedings and claims from time to time relating to the intellectual
property of others in the ordinary course of our business. We may incur
substantial expenses in defending against these third-party infringement claims,
regardless of their merit. Successful infringement claims against us may result
in substantial monetary liability or may materially disrupt the conduct of our
business.

FACILITIES

    Our principal executive offices are currently located in approximately
15,000 square feet of office space in New York, New York. Additionally, in
June 1999 we entered into an agreement to lease approximately 32,000 square feet
of office space in another facility in New York, New York, with an option for an
additional 32,000 square feet available by March 2001. We expect to move our
principal executive offices to the new facilities in February 2000. We also
lease office space in:

    - Atlanta, Georgia;

    - Boston, Massachusetts;

    - Dallas, Texas;

    - Florham Park, New Jersey;

    - Herndon, Virginia;

    - Pleasanton, California;

    - Santa Cruz, California;

    - London, England; and

    - Amsterdam, The Netherlands.

    We believe that our existing facilities are adequate for our current needs
and that additional space will be available as needed.

LEGAL PROCEEDINGS

    We are not a party to any material legal proceedings.

CLASSIFIED BOARD OF DIRECTORS

    Our board of directors is divided into three classes of directors serving
staggered three year terms. Upon expiration of the term of a class of directors,
the directors in that class will be elected for three-year terms at the annual
meeting of stockholders in the year in which their term expires. Our board of
directors has resolved that Messrs. Pettengill, Belau and Duffy will be Class I

provisions, when coupled with the provision of our amended and restated

directorships or increase the size of the board of directors, may delay a
stockholder from removing incumbent directors and simultaneously gaining control
of the board of directors by filling the vacancies with its own nominees.

OPTION GRANTS IN LAST FISCAL YEAR

    The following table sets forth grants of stock options for the year ended
December 31, 1998 to our Chief Executive Officer and to each of our most highly
compensated executive officers, other than the Chief Executive Officer, whose
salary and bonus for such fiscal year exceeded $100,000. We have never granted
any stock appreciation rights. The potential realizable value is calculated
based on the term of the option at its time of grant. It is calculated assuming
that the fair market value of common stock on the date of grant appreciates at
the indicated annual rate compounded annually for the entire term of the option
and that the option is exercised and sold on the last day of its term for the
appreciated stock price. These numbers are calculated based on the requirements
of the Securities and Exchange Commission and do not reflect our estimate of
future stock price growth. The percentage of total options granted to employees
in the last fiscal year is based on options to purchase an aggregate of
2,427,000 shares of common stock granted under our option plans. There was no
public market for our

                                       49

common stock as of December 31, 1998. Accordingly, the fair market value on

    The following table sets forth information concerning the value realized
upon exercise of options during 1998 and the number and value of unexercised
options held by each of our named executive officers at December 31, 1998. There
was no public market for our common stock as of December 31, 1998. Accordingly,
the values set forth below have been calculated on the basis of the fair market

competing with us and soliciting our employees for a period of 6 and 12 months,
respectively, from the termination of his employment. The agreement is in effect
until terminated by either party by giving at least 3 months notice to the other
party.

    Our agreement with Mr. Dorsey provides for an initial base salary of
$210,000 and an annual bonus of up to a maximum of $75,000. Under the agreement,
Mr. Dorsey received options to purchase 175,000 shares of our common stock at a
price of $11.05 per share, which vest over 4 years. Our agreement further
provides that Mr. Dorsey will receive an automobile allowance of $650 per month.
The agreement prohibits Mr. Dorsey from competing with us and soliciting our
employees for a period

                                       51

of one year from the termination of his employment. The agreement has an initial
term of three years, and renews automatically for successive one year periods
unless written notice is given by either party.

1999 STOCK INCENTIVE PLAN

    The 1999 Stock Incentive Plan is intended to serve as the successor equity
incentive program to our 1998 Stock Option/Stock Issuance Plan and our 1998
California Stock Option/Stock Issuance Plan. The 1999 Plan became effective upon
its adoption by the board of directors on September 14, 1999. It will be
approved by the stockholders prior to the date of this offering.

    6,665,600 shares of common stock have been authorized for issuance under the
1999 Plan. This share reserve consists of the shares which were available for
issuance under the predecessor plans on the effective date of the 1999 Plan plus
an additional increase of 2,345,597 shares. The share reserve will automatically
be increased on the first trading day of January each calendar year, beginning
in January 2001, by a number of shares equal to 1% of the total number of shares
of common stock outstanding on the last trading day of the immediately preceding
calendar year, but no such annual increase will exceed 500,000 shares. However,
in no event may any one participant in the 1999 Plan receive option grants or
direct stock issuances for more than 500,000 shares in the aggregate per
calendar year.

    Outstanding options under the predecessor plans will be incorporated into
the 1999 Plan upon the date of this offering, and no further option grants will
be made under those plans. The incorporated options will continue to be governed
by their existing terms, unless our compensation committee extends one or more
features of the 1999 Plan to those options. However, except as otherwise noted
below, the outstanding options under the predecessor plans contain substantially
the same terms and conditions summarized below for the discretionary option
grant program under the 1999 Plan.

    The 1999 Plan has five separate programs:

    - the discretionary option grant program under which eligible individuals in
      our employ or service (including officers, non-employee board members and
      consultants) may be granted options to purchase shares of our common
      stock;

    - the stock issuance program under which these individuals may be issued
      shares of our common stock directly, with the purchase of such shares or
      as a bonus tied to the performance of services;

    - the salary investment option grant program under which executive officers
      and other highly compensated employees may elect to apply a portion of
      their base salary to the acquisition of special below-market stock option
      grants;

    - the automatic option grant program under which option grants will
      automatically be made at periodic intervals to eligible non-employee board
      members; and

    - the director fee option grant program under which non-employee board
      members may elect to apply a portion of their retainer fee to the
      acquisition of special below-market stock option grants.

    The discretionary option grant and stock issuance programs will be
administered by our compensation committee. This committee will determine which
eligible individuals are to receive option grants or stock issuances, the time
or times when such option grants or stock issuances are to be made, the number
of shares subject to each such grant or issuance, the exercise or purchase price
for each such grant or issuance, the status of any granted option as either an
incentive stock option or a non-statutory stock option under the federal tax
laws, the vesting schedule to be in effect for the option grant or stock
issuance and the maximum term for which any granted option is to remain
outstanding. The committee will also select the executive officers and other
highly compensated employees who may

                                       52
<PAGE>
participate in the salary investment option grant program in the event that
program is activated for one or more calendar years. Neither the compensation
committee nor the board will exercise any administrative discretion with respect
to option grants made under the salary investment option grant program or under
the automatic option grant or director fee option grant program for the non-
employee board members.

    The exercise price for the options may be paid in cash or in shares of our
common stock valued at fair market value on the exercise date. The option may
also be exercised through a same-day sale program without any cash outlay by the
optionee. In addition, the compensation committee may allow a participant to pay
the option exercise price or direct issue price (and any associated withholding
taxes incurred in connection with the acquisition of shares) with a
full-recourse, interest-bearing promissory note.

    In the event that we are acquired, whether by merger or asset sale or
board-approved sale by the stockholders of more than 50% of our voting stock,
each outstanding option under the discretionary option grant program which is
not to be assumed by the successor corporation or otherwise continued will
automatically accelerate in full, and all unvested shares under the
discretionary option grant and stock issuance programs will immediately vest,
except to the extent our repurchase rights with respect to those shares are to
be assigned to the successor corporation or otherwise continued in effect. The
compensation committee may grant options under the discretionary option grant
program which will accelerate in the acquisition even if the options are assumed
or which will accelerate if the optionee's service is subsequently terminated.
The compensation committee may grant options and issue shares which accelerate
in connection with a hostile change in control effected through a successful
tender offer for more than 50% of our outstanding voting stock or by proxy
contest for the election of board members) or the options and shares may
accelerate upon a subsequent termination of the individual's service.

    Options currently outstanding under the plan may be assumed by the successor
corporation in an acquisition; such options are not by their terms subject to
acceleration at the time of an acquisition or a change in control or upon the
termination of the optionee's service following any such transaction.

    Stock appreciation rights may be issued under the discretionary option grant
program which will provide the holders with the election to surrender their
outstanding options for an appreciation distribution from us equal to the fair
market value of the vested shares subject to the surrendered option less the
aggregate exercise price payable for such shares. This appreciation distribution
may be made in cash or in shares of our common stock. There are currently no
outstanding stock appreciation rights under the predecessor plans.

    The compensation committee has the authority to cancel outstanding options
under the discretionary option grant program (including options incorporated
from predecessor plans) in return for the grant of new options for the same or
different number of option shares with an exercise price per share based upon
the fair market value of the common stock on the new grant date.

    In the event the compensation committee elects to activate the salary
investment option grant program for one or more calendar years, each of our
executive officers and other highly compensated employees selected for
participation may elect to reduce his or her base salary for that calendar year
by a specified dollar amount not less than $5,000 nor more than $50,000. In
return, the individual will automatically be granted, on the first trading day
in the calendar year for which the salary reduction is to be in effect, a
non-statutory option to purchase that number of shares of common stock
determined by dividing the salary reduction amount by two-thirds of the fair
market value per share of our common stock on the grant date. The option
exercise price will be equal to one-third of the fair market value of the option
shares on the grant date. As a result, the fair market value of the option
shares on the grant date less the exercise price payable for those shares will
be equal to the salary reduction amount. The option will become exercisable in a
series of 12 equal monthly installments over the

                                       53
<PAGE>
calendar year for which the salary reduction is to be in effect and will be
subject to full and immediate vesting in the event of an acquisition or change
in control.

    Under the automatic option grant program, each individual who first joins
our board after the effective date of this offering as a non-employee board
member will automatically be granted an option for 25,000 shares of our common
stock at the time of his or her commencement of board service. In addition, on
the date of each annual stockholders meeting, beginning with the 2001 meeting,
each individual who has served as a non-employee board member since the last
annual stockholders meeting will receive an option grant to purchase
2,500 shares of our common stock. Each automatic grant will have an exercise
price equal to the fair market value per share of our common stock on the grant
date and will have a maximum term of 10 years, subject to earlier termination
following the optionee's cessation of board service. Each option will be
immediately exercisable, subject to our right to repurchase any unvested shares,
at the original exercise price, at the time of the board member's cessation of
service. The options will vest, and our repurchase right will lapse, with
respect to, the initial 25,000-share option grant in a series of four (4) equal
successive annual installments upon the optionee's completion of each year of
service over the four (4)-year period measured from the grant date. However,
each such outstanding option will immediately vest upon an acquisition or change
in control or the death or disability of the optionee while serving as a board
member. Each 2,500-share option grant will be fully vested on grant.

    If the director fee option grant program is put into effect in the future,
then each non-employee board member may elect to apply all or a portion of any
cash retainer fee for the year to the acquisition of a below-market option
grant. The option grant will automatically be made on the first trading day in
January in the year for which the non-employee board member would otherwise be
paid the cash retainer fee in the absence of his or her election. The option
will have an exercise price per share equal to one-third of the fair market
value of the option shares on the grant date, and the number of shares subject
to the option will be determined by dividing the amount of the retainer fee
applied to the program by two-thirds of the fair market value per share of our
common stock on the grant date. As a result, the fair market value of the option
shares on the grant date less the exercise price payable for those shares will
be equal to the portion of the retainer fee applied to that option. The option
will become exercisable in a series of twelve equal monthly installments over
the calendar year for which the election is in effect. However, the option will
become immediately exercisable for all the option shares upon the death or
disability of the optionee while serving as a board member.

    Limited stock appreciation rights will automatically be included as part of
each grant made under the automatic option grant, director fee option grant and
salary investment option grant programs and may be granted to one or more
officers as part of their option grants under the discretionary option grant
program. Options with this limited stock appreciation right may be surrendered
to us upon the successful completion of a hostile tender offer for more than 50%
of our outstanding voting stock. In return for the surrendered option, the
optionee will be entitled to a cash distribution from us in an amount per
surrendered option share equal to the highest price per share of our common
stock paid in connection with the tender offer less the exercise price payable
for such share.

    The board may amend or modify the 1999 Plan at any time, subject to any
required stockholder approval. The 1999 Plan will terminate no later than
September 14, 2009.

EMPLOYEE STOCK PURCHASE PLAN

    Our Employee Stock Purchase Plan was adopted by the board on September 14,
1999 and will be approved by the stockholders prior to the date of this
offering. The plan will become effective immediately upon the execution of the
underwriting agreement for this offering. The plan is designed to allow our
eligible employees and those of our participating subsidiaries to purchase
shares of our

                                       54
<PAGE>
common stock, at semi-annual intervals, through periodic payroll deductions. A
total of 750,000 shares of our common stock will be issued under the plan.

    The plan will have a series of successive offering periods, each with a
maximum duration of 24 months. The initial offering period will begin on the day
the underwriting agreement is executed in connection with this offering and will
end on the last business day in October 2001. The next offering period will
begin on the first business day in November 2001, and subsequent offering
periods will be set by our compensation committee.

    Individuals who are eligible employees on the start date of any offering
period may enter the plan on that start date or on any subsequent semi-annual
entry date (generally May 1 or November 1 each year). Individuals who become
eligible employees after the start date of the offering period may join the plan
on any subsequent semi-annual entry date within that period.

    A participant may contribute up to 10% of his or her cash earnings through
payroll deductions and the accumulated payroll deductions will be applied to the
purchase of shares on the participant's behalf on each semi-annual purchase date
(the last business day in January and July each year). The purchase price per
share will be 85% of the lower of the fair market value of our common stock on
the participant's entry date into the offering period or the fair market value
on the semi-annual purchase date. The first purchase date will occur on the last
business day in April 2000. In no event, however, may any participant purchase
more than 500 shares, nor may all participants in the aggregate purchase more
than 187,500 shares on any one semi-annual purchase date. Should the fair market
value of our common stock on any semi-annual purchase date be less than the fair
market value on the first day of the offering period, then the current offering
period will automatically end and a new offering period will begin, based on the
lower fair market value.

    The board may at any time amend or modify the plan. The plan will terminate
no later than the last business day in October 2009.

                              CERTAIN TRANSACTIONS

RELATIONSHIP WITH CISCO

    In September 1999, we sold 1,242,000 shares of our common stock to Cisco for
$12.00 per share. In connection with the investment, we have agreed to nominate
a person designated by Cisco to our Board of Directors so long as Cisco owns
more than 750,000 shares of our common stock. Additionally, we provide network
consulting services to Cisco pursuant to an existing agreement negotiated by the
parties in an arms-length transaction. This agreement expires in May 2003 and
governs the terms and conditions that apply to all consulting services performed
by us for Cisco and for customers of Cisco. In fiscal 1998 and the six months
ended June 30, 1999, revenues from Cisco were $35,190 and $883,388,
respectively. Inder Sidhu, one of our directors, is the Vice President of
Worldwide Professional Services at Cisco.

SALE OF COMMON STOCK

    In September 1999, we sold 94,867 and 18,133 shares of our common stock to
General Atlantic Partners 57 and GAP Coinvestment Partners II, respectively, for
$12.00 per share. Peter L. Bloom and Braden R. Kelly, our directors, are
respectively a managing member and an associate of General Atlantic Partners,
LLC. General Atlantic Partners, LLC is the general partner of General Atlantic
Partners 57 and the managing members of General Atlantic Partners, LLC are also
the general partners of GAP Coinvestment Partners II.

TRIBECA SOFTWARE

    In March 1998, we made a pro rata distribution of all of the outstanding
shares of our former subsidiary, Tribeca Software, Inc., to our stockholders. Of
the 1,501,700 then outstanding shares of Tribeca, we distributed the following
amounts to our officers, directors and 5% stockholders and their affiliates:

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

    (1) Boyce Meyer was the father of Eric Meyer and the stepfather of Robert L.
Belau.

    Subsequent to this transaction, Tribeca purchased from us, and we assigned
to Tribeca, network management software and other assets, including computer and
office equipment. As payment for these assets, Tribeca gave us a demand note in
the amount of $130,000, which accrued interest at 8% per annum. Additionally, we
gave Tribeca a $1,000,000 line of credit at an interest rate of 8% per annum. In
March 1999, Tribeca paid us the full amounts due under the demand note and line
of credit and the line of credit was terminated. The largest amount outstanding
under the line of credit was $988,800.

    From March 1998 through June 1999, we performed payroll, accounting and
other administrative services for Tribeca for a fee of $7,000 per month.
Additionally, Tribeca leases office space and

                                       56
<PAGE>
equipment from us for approximately $12,000 per month. We also have an oral
agreement with Tribeca to purchase at a discount and resell its software. In
1998, sales of Tribeca's software accounted for approximately $100,000 of our
revenues. We believe that these transactions were on terms that are no less
favorable than those that could be obtained from unaffiliated third parties.

    Ronald G. Pettengill, Jr., our Chairman and Chief Executive Officer, Robert
L. Belau, our President, and Donald J. Duffy and Eric Meyer, our directors, are
directors of Tribeca and own shares of common stock of Tribeca. Additionally,
Messrs. Pettengill and Belau serve as executive officers of Tribeca.

SALE OF SERIES A CONVERTIBLE PREFERRED STOCK AND WARRANTS

    In March 1999, we sold 6,512,316 shares of series A convertible preferred
stock and warrants to purchase the number of shares of our common stock that
equals 15% of the number of shares registered in this offering, at the initial
public offering price, to six accredited investors for an aggregate purchase
price of approximately $18.6 million. General Atlantic Partners 54, L.P.
purchased 5,350,441 shares and GAP Coinvestment Partners II purchased 1,112,765
shares. Peter L. Bloom and Braden R. Kelly, our directors, are respectively a
managing member and an associate of General Atlantic Partners, LLC. General
Atlantic Partners, LLC is the general partner of General Atlantic Partners 54
and the managing members of General Atlantic Partners, LLC are also the general
partners of GAP Coinvestment Partners II. The purchase price for the series A
convertible preferred stock was $2.85 per share. On the closing of this
offering, the series A convertible preferred stock will automatically convert
into 6,512,316 shares of common stock. Under the terms of the warrants, a notice
of exercise was required to be sent within twenty business days of the initial
filing of this registration statement. As no notice of exercise was received
within this exercise period, the warrants have terminated and are no longer
exercisable.

SHARE REDEMPTION

    As a condition of the March 1999 sale of series A convertible preferred
stock and warrants, we were required to repurchase approximately $8.4 million of
our common stock. Accordingly, we made an offer to each of our stockholders to
repurchase their shares at a price of $2.94 per share. Subsequently, in
March 1999, we repurchased a total of 2,855,100 shares of common stock from 31
of our stockholders who elected to sell shares for an aggregate purchase price
of approximately $8.4 million. Of these, we purchased the following amounts from
our officers, directors and 5% stockholders and their affiliates:

MEYER, DUFFY & ASSOCIATES

    We had an agreement with Meyer, Duffy & Associates, Inc. pursuant to which
Meyer Duffy & Associates provided us with consulting and advisory services
regarding capital raising and strategic partnerships. Eric Meyer and Donald J.
Duffy, our directors, serve as co-managing Directors of Meyer, Duffy &
Associates. We paid Meyer, Duffy & Associates a retainer fee of $5,000 per month
in connection with these services through March 31, 1999, the date that the
agreement terminated. Additionally, in August 1998, we loaned Meyer, Duffy &
Associates, L.P., in connection with the exercise of options, $300,000 at an
interest rate of 7% per annum. Meyer, Duffy & Associates, L.P. repaid this loan
in March 1999. Messrs. Meyer and Duffy are the general partners of Meyer, Duffy
& Associates, L.P.

LOANS TO OFFICERS

    In August 1998, in connection with the exercise of options, we loaned each
of Ronald G. Pettengill, Jr., our Chairman and Chief Executive Officer and
Robert L. Belau, our President, $97,500 at an interest rate of 7% per annum.
Messrs. Pettengill and Belau repaid those loans in March 1999. In addition to
these loans, from time to time, we have advanced loans to Messrs. Pettengill and
Belau. As of December 31, 1998 the amounts outstanding under these advances for
Messrs. Pettengill and Belau was $15,000 and $13,402, respectively which
represents the largest amounts outstanding under these advances during fiscal
1998. There are currently no advances outstanding. We may in the future make
loans to our officers.

OPTION GRANTS

    We granted each of Messrs. Bloom, Duffy, Kelly and Meyer, our non-employee
directors, options to purchase 25,000 shares of our common stock at a price of
$4.00 per share. We granted each of Messrs. Sidhu and Wyman, our non-employee
directors, options to purchase 25,000 shares of our common stock at a price of
$11.05 per share. Additionally, in 1999, we granted to Messrs. Pettengill,
Belau, Dorsey, Joseph, Humes, Holt, Sethi, Wright and Papilsky options to
purchase 200,000; 200,000; 175,000; 100,000; 60,000; 130,000; 70,000; 80,000 and
50,000, respectively. Please see "Management--Employment Agreements." For
additional information regarding the grant of stock options to executive
officers and directors, please see "Management--Director Compensation,"

Stockholders."

AGREEMENTS WITH UNDERWRITERS

    We provide network consulting services to Bear, Stearns & Co. Inc.,
Donaldson, Lufkin & Jenrette and First Union Capital Markets Corp. pursuant to
agreements they have entered into with us. The terms of these agreements were
negotiated by the parties in arms-length transactions and were entered into
prior to our selection of the underwriters of this offering. In 1998, revenues
derived from Bear Stearns, Donaldson, Lufkin & Jenrette and its affiliates, and
First Union equalled $5.4 million, $162,689 and $50,000, respectively. For the
six months ended June 30, 1999, revenues derived from Bear Stearns and
Donaldson, Lufkin & Jenrette and its affiliates equalled $5.2 million and
$855,000, respectively. We may provide network consulting services to other
underwriters in this offering after the date of this prospectus.

    We recently adopted a policy that all transactions with officers, directors,
5% stockholders and their affiliates be entered into only if they are approved
by a majority of the disinterested independent directors, are on terms no less
favorable to us than could be obtained from unaffiliated parties and are
reasonably expected to benefit us.

                             PRINCIPAL STOCKHOLDERS

    The following table sets forth information with respect to beneficial
ownership of our common stock, as of September 30, 1999 and as adjusted to
reflect the sale of common stock offered by us in this offering for:

    - each person known by us to beneficially own more than 5% of our common
      stock;

    - each executive officer named in the Summary Compensation Table;

    - each of our directors; and

    - all of our executive officers and directors as a group.

    Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission and includes voting or investment power with
respect to the securities. Unless otherwise indicated, the address for those
listed below is c/o Predictive Systems, Inc., 145 Hudson Street, New York, New
York 10013. Except as indicated by footnote, and subject to applicable community
property laws, the persons named in the table have sole voting and investment
power with respect to all shares of common stock shown as beneficially owned by
them. The number of shares of common stock outstanding used in calculating the
percentage for each listed person includes the shares of common stock underlying
options held by such persons that are exercisable within 60 days of
September 30, 1999, but excludes shares of common stock underlying options held
by any other person. Percentage of beneficial ownership is based on 18,790,080

shares is not exercised.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

    Our amended and restated certificate of incorporation, which will become
effective upon the closing of this offering, authorizes the issuance of up to
200,000,000 shares of common stock, par value $.001 per share, and 10,000,000
shares of preferred stock, par value $.001 per share, the rights and preferences
of which may be established from time to time by our board of directors. As of
September 30, 1999, 12,277,764 shares of common stock were outstanding and
6,512,316 shares of series A convertible preferred stock convertible into the
same amount of shares of common stock were outstanding. As of September 30,
1999, we had 76 stockholders.

COMMON STOCK

    Under our amended and restated certificate of incorporation, holders of our
common stock are entitled to one vote for each share held of record on all
matters submitted to a vote of the stockholders, including the election of
directors. They do not have cumulative voting rights. Subject to preferences
that may be applicable to any then-outstanding preferred stock, holders of our
common stock are entitled to receive ratably dividends, if any, as may be
declared by the board of directors out of legally available funds. In case of a
liquidation, dissolution or winding up of Predictive, the holders of common
stock will be entitled to share ratably in the net assets legally available for
distribution to shareholders after payment of all of our liabilities and any
preferred stock then outstanding. Holders of common stock have no preemptive or
conversion rights or other subscription rights. There are no redemption or
sinking fund provisions applicable to the common stock. The rights, preferences
and privileges of holders of common stock are subject to the rights of the
holders of shares of any series of preferred stock that we may designate and
issue in the future. After the closing of this offering, there will be no shares
of preferred stock outstanding.

PREFERRED STOCK

    Under our amended and restated certificate of incorporation, our board of
directors has the authority, without further action by the stockholders, to
issue from time to time, shares of preferred stock in one or more series. The
board of directors may fix the number of shares, designations, preferences,
powers and other special rights of the preferred stock. The preferences, powers,
rights and restrictions of different series of preferred stock may differ. The
issuance of preferred stock could decrease the amount of earnings and assets
available for distribution to holders of common stock or affect adversely the
rights and powers, including voting rights, of the holders of common stock. Such
issuance may also have the effect of delaying, deferring or preventing a change
in control of Predictive. We have no current plans to issue any shares of
preferred stock.

REGISTRATION RIGHTS

    In March 1999, we entered into registration rights agreement with some of
our stockholders, including: General Atlantic Partners 54; GAP Coinvestment
Partners II; Ronald G. Pettengill, Jr., our Chief Executive Officer; Robert L.
Belau, our President; Eric Meyer and Donald Duffy, our directors; and Meyer,
Duffy and Associates. This agreement was amended in September 1999 to include
General Atlantic Partners 57. Under the terms of this agreement, as amended, at
any time after the first anniversary of the effective date of this offering,
each of General Atlantic Partners 54, General Atlantic Partners 57 and GAP
Coinvestment Partners II may, on two occasions only, require us to register for
sale all or any portion of the shares of common stock issuable upon conversion
of the preferred shares held by them. We are also obligated to register some
shares of common stock held by parties to the registration rights agreement if
they request to be included in the registration. In September 1999, we entered
into a separate registration rights agreement with Cisco Systems.

                                       61
<PAGE>
    Under each of these agreements, if we become eligible to file registration
statements on Form S-3, some parties to the registration rights agreements may
require us to file a registration statement on Form S-3 under the Securities Act
with respect to some shares of common stock held by them. We are also obligated
to register some shares of common stock held by parties to the registration
rights agreements if they request to be included in the registration. In
addition, holders of common stock who are parties to the registration rights
agreements will be entitled to require us to register some of their common stock
when we register stock of other stockholders. This type of registration right is
known as a "piggyback" registration right.

    The foregoing registration rights are subject to certain conditions and
limitations, including:

    - The right of the underwriters in any underwritten offering to limit the
      number of shares of common stock held by stockholders with registration
      rights to be included in any demand, S-3 or piggyback registration; and

    - Our right to delay for up to 90 days the filing or effectiveness of a
      registration statement pursuant to a demand for registration if the board
      of directors of determines that the registration would not be in our best
      interest at that time.

    We are generally required to bear all of the expenses of all registrations,
except underwriting discounts and commissions. Registration of any of the shares
of common stock held by stockholders with registration rights would result in
those shares becoming freely tradable without restriction under the Securities
Act immediately after effectiveness of the registration. We have agreed to
indemnify the holders of registration rights in connection with demand, S-3 and
piggyback registration under the terms of our registration rights agreements.

ANTI-TAKEOVER EFFECTS OF DELAWARE LAW AND OUR AMENDED AND RESTATED CERTIFICATE
OF INCORPORATION AND BYLAWS

    Provisions of our amended and restated certificate of incorporation and
amended and restated bylaws, which are summarized in the following paragraphs,
may have an anti-takeover effect and may delay, defer or prevent a tender offer
or takeover attempt that a stockholder might consider in its best interest,
including those attempts that might result in a premium over the market price
for the shares held by stockholders.

CLASSIFIED BOARD OF DIRECTORS

    Our board of directors is divided into three classes of directors serving
staggered three-year terms. As a result, approximately one-third of the board of
directors will be elected each year. These provisions, when coupled with the
provision of our amended and restated certificate of incorporation authorizing
the board of directors to fill vacant directorships or increase the size of the
board of directors, may delay a stockholder from removing incumbent directors
and simultaneously gaining control of the board of directors by filling the
vacancies created by such removal with its own nominees.

CUMULATIVE VOTING

    Our amended and restated certificate of incorporation expressly denies
stockholders the right to cumulate votes in the election of directors.

STOCKHOLDER ACTION; SPECIAL MEETING OF STOCKHOLDERS

    Our amended and restated certificate of incorporation eliminates the ability
of stockholders to act by written consent. It further provides that special
meetings of our stockholders may be called only by the chairman of the board of
directors or a majority of the board of directors.

                                       62
<PAGE>
ADVANCE NOTICE REQUIREMENTS FOR STOCKHOLDER PROPOSALS AND DIRECTOR NOMINATIONS

    Our amended and restated by-laws provide that stockholders seeking to bring
business before an annual meeting of stockholders, or to nominate candidates for
election as directors at an annual meeting of stockholders, must provide timely
notice thereof in writing. To be timely, a stockholder's notice must be received
at our principal executive offices not less than 60 days nor more than 90 days
prior to the anniversary date of the immediately preceding annual meeting of
stockholders. In the event that the annual meeting is called for a date that is
not within thirty (30) days before or after the anniversary date, in order to be
timely, notice from the stockholder must be received no later than the tenth day
following the date on which notice of the annual meeting was mailed to
stockholders or made public, whichever occurred earlier. In the case of a
special meeting of stockholders called for the purpose of electing directors,
notice by the stockholder in order to be timely must be received not later than
the close of business on the tenth day following the day on which notice was
mailed or public disclosure of the date of the special meeting was made,
whichever first occurs. Our amended and restated by-laws also specify certain
requirements as to the form and content of a stockholder's notice. These
provisions may preclude stockholders from bringing matters before an annual or
special meeting of stockholders or from making nominations for directors at
these meetings.

AMENDMENTS; SUPERMAJORITY VOTE REQUIREMENTS

    The Delaware General Corporation Law provides generally that the affirmative
vote of a majority of the shares entitled to vote on any matter is required to
amend a corporation's certificate of incorporation or bylaws, unless a
corporation's certificate of incorporation or bylaws, as the case may be,
requires a greater percentage. Our amended and restated certificate of
incorporation imposes supermajority vote requirements in connection with the
amendment of provisions of our amended and restated certificate of incorporation
and amended and restated bylaws, including those provisions relating to the
classified board of directors and the ability of stockholders to call special
meetings.

AUTHORIZED BUT UNISSUED SHARES

    The authorized but unissued shares of common stock and preferred stock are
available for future issuance without stockholder approval. These additional
shares may be utilized for a variety of corporate purposes, including future
public offerings to raise additional capital, corporate acquisitions and
employee benefit plans. The existence of authorized but unissued shares of
common stock and preferred stock could render more difficult or discourage an
attempt to obtain control of us by means of a proxy contest, tender offer,
merger or otherwise.

    The Delaware General Corporation Law provides generally that the affirmative
vote of a majority of the shares entitled to vote on any matter is required to
amend a corporation's certificate of incorporation or bylaws, unless a
corporation's certificate of incorporation or bylaws, as the case may be,
requires a greater percentage. Our amended and restated certificate of
incorporation imposes supermajority vote requirements in connection with various
business combination transactions and the amendment of various provisions of our
amended and restated certificate of incorporation and amended and restated
bylaws, including those provisions relating to the classified board of
directors, action by written consent and special meetings by stockholders.

TRANSFER AGENT AND REGISTRAR

    The Transfer Agent and Registrar for our common stock will be American Stock
Transfer & Trust Company, New York, New York.

LISTING

    We have applied to list our common stock on the Nasdaq National Market under
the trading symbol "PRDS."

<PAGE>
                        SHARES ELIGIBLE FOR FUTURE SALE

    Prior to this offering, there has not been any public market for our common
stock, and we cannot predict the effect, if any, that market sales of shares of
common stock or the availability of shares of common stock for sale will have on
the market price of the common stock prevailing from time to time. Nevertheless,
sales of substantial amounts of our common stock in the public market, or the
perception that such sales could occur, could adversely affect the market price
of the common stock and could impair our future ability to raise capital through
the sale of its equity securities.

    Upon completion of this offering, we will have an aggregate of
22,790,080 shares of common stock outstanding, assuming no exercise of the
underwriters' over-allotment option and no exercise of outstanding options or
warrants. Of the outstanding shares, the 4,000,000 shares sold in this offering
will be freely tradable, except that any shares held by our "affiliates," as
defined in Rule 144 promulgated under the Securities Act of 1933, may only be
sold in compliance with the limitations described below. The remaining
18,790,080 shares of common stock will be deemed "restricted securities" as
defined under Rule 144. Restricted securities may be sold in the public market
only if registered or if they qualify for an exemption from registration under
Rules 144, 144(k) or 701 promulgated under the Securities Act, which rules are
summarized below. Subject to the lock-up agreements described below and the
provisions of Rules 144, 144(k) and 701, these 18,790,080 shares will be
available for sale in the public market as follows:

</TABLE>

    In general, under Rule 144, as currently in effect, a person, including an
affiliate, who has beneficially owned shares for at least one year is entitled
to sell, within any three-month period commencing 90 days after the date of this
prospectus, a number of shares that does not exceed the greater of (1) 1% of the
then outstanding shares of common stock (approximately 228,000 shares
immediately after this offering) or (2) the average weekly trading volume in the
common stock during the four calendar weeks preceding the date on which notice
of such sale is filed, subject to certain restrictions. In addition, a person
who is not deemed to have been an affiliate of Predictive at any time during the
90 days preceding a sale and who has beneficially owned the shares proposed to
be sold for at least two years would be entitled to sell such shares under
Rule 144(k) without regard to the requirements described above. To the extent
that shares were acquired from an affiliate of ours, that person's holding
period for the purpose of selling under Rule 144 commences on the date of
transfer from the affiliate. Notwithstanding the foregoing, to the extent the
shares were acquired through the cashless exercise of a stock option or a
warrant, that person's holding period for effecting a sale under Rule 144
commences on the date of the option or warrant grant. In general, under
Rule 701 of the Securities Act as currently in effect, any of our employees,
consultants or advisors who purchased our shares in connection with a
compensatory stock or option plan or other written agreement is eligible to
resell such shares after the effective date of this offering in reliance on
Rule 144, but without compliance with certain restrictions, including the
holding period in Rule 144.

    As of the date of this prospectus, options to purchase a total of
10,111,463 shares of common stock are outstanding, of which 4,899,800 are
currently exercisable (without regard to the 180-day lock up period). Promptly
after the closing of this offering, we intend to file a registration statement
to register for resale all shares of common stock issued or issuable under its
1999 employee stock purchase plan and not otherwise freely transferable.
Accordingly, shares covered by that registration

                                       64
<PAGE>
statement will be eligible for sale in the public markets, unless those options
are subject to vesting restrictions.

    Our directors and officers and certain of our stockholders who hold
18,099,030 shares in the aggregate have agreed that they will not sell, directly
or indirectly, any shares of common stock (other than shares of common stock
purchased as part of the directed share program in connection with this
offering) without the prior written consent of BancBoston Robertson
Stephens Inc. for a period of 180 days from the date of this prospectus.

    We have agreed not to sell or otherwise dispose of any shares of our common
stock during the 180 day period following the date of the prospectus, except we
may issue, and grant options to purchase, shares of common stock under our stock
option plan.

    Following this offering, under certain circumstances and subject to certain
conditions, holders of 8,122,006 shares of our outstanding common stock will
have certain demand registration rights with respect to their shares of common
stock (subject to the 180-day lock-up arrangement described above) to require us
to register their shares of common stock under the Securities Act, and they will
have certain rights to participate in any future registration of securities by
us. Additionally, holders of 8,791,952 shares of our outstanding common stock
will have some rights to participate in any future registrations of securities
by us. See "Description of Capital Stock-Registration Rights."

    We have been advised that the underwriters propose to offer the shares of
common stock to the public at the public offering price located on the cover
page of this prospectus and to dealers at that price less a concession of not in
excess of $      per share, of which $      may be reallowed to other dealers.
After the initial public offering, the public offering price, concession and
reallowance to dealers may be reduced by the representatives. No reduction in
this price will change the amount of proceeds to be received by us as indicated
on the cover page of this prospectus.

    OVER-ALLOTMENT OPTION.  We have granted to the underwriters an option,
exercisable during the 30-day period after the date of this prospectus, to
purchase up to 600,000 additional shares of common stock at the same price per
share as we will receive for the 4,000,000 shares that the underwriters have
agreed to purchase. To the extent that the underwriters exercise this option,
each of the underwriters will have a firm commitment to purchase approximately
the same percentage of additional shares that the number of shares of common
stock to be purchased by it shown in the above table represents as a percentage
of the 4,000,000 shares offered by this prospectus. If purchased, the additional
shares will be sold by the underwriters on the same terms as those on which the
4,000,000 shares are being sold. We will be obligated, under this option, to
sell shares to the extent the option is exercised. The underwriters may exercise
the option only to cover over-allotments made in connection with the sale of the
4,000,000 shares of common stock offered by this prospectus.

    The following table shows the per share and total underwriting discounts and
commissions to be paid by us to the underwriters. This information is presented
assuming either no exercise or full exercise by the underwriters of their
over-allotment option.

    INDEMNITY.  The underwriting agreement contains covenants of indemnity among
the underwriters and us against certain civil liabilities, including liabilities
under the Securities Act and liabilities arising from breaches of representation
and warranties contained in the underwriting agreement.

    FUTURE SALES.  Each of our executive officers, directors and other
significant stockholders of record has agreed with the representatives, for a
period of 180 days after the date of this prospectus, not to offer to sell,
contract to sell or otherwise sell, dispose of, loan, pledge or grant any rights
with respect to any shares of common stock, any options or warrants to purchase
any shares of common stock, or any securities convertible into or exchangeable
for shares of common stock owned as of the date of this prospectus or acquired
directly from us by these holders or with respect to which they have or may
acquire the power of disposition, without the prior written consent of
BancBoston Robertson Stephens Inc. However, BancBoston Robertson Stephens Inc.
may, in its sole discretion and at any time without notice, release all or any
portion of the securities subject to lock-up agreements. There are no agreements
between the representatives and any of our stockholders providing consent by the
representatives to the sale of shares prior to the expiration of the 180-day
lock-up period. In addition, we have generally agreed that, during the 180-day
lock-up period, we will not, without the prior written consent of BancBoston
Robertson Stephens Inc., (a) consent to the disposition of any shares held by
stockholders prior to the expiration of the 180-day lock-up period or
(b) issue, sell, contract to sell or otherwise dispose of, any shares of common
stock, any options or warrants to purchase any shares of common stock, or any
securities convertible into, exercisable for or exchangeable for shares of
common stock, other than our sale of shares in the offering, our issuance of
common stock upon the exercise of currently outstanding options and warrants,
and our issuance of incentive awards under our stock incentive plan. Please see
"Shares Eligible for Future Sale."

    INTERNET DISTRIBUTION.  A limited number of shares will be made available to
the customers of E*TRADE Securities. E*TRADE will make a copy of the prospectus
in electronic format available on its Web site. E*TRADE will accept conditional
offers to purchase shares from all of its customers that complete and pass an
online eligibility profile. In the event that the demand for shares from the
customers of E*TRADE exceeds the amount of shares allocated to it, E*TRADE will
use a random allocation methodology to distribute shares in even lots of 100
shares per customer. These are no plans to direct shares to particular Internet
purchasers.

    DIRECTED SHARES.  We have requested that the underwriters reserve up to five
percent of the shares of common stock for sale at the initial public offering
price to directors, officers, employees and other individuals designated by us.

    The underwriters have informed us that they do not intend to confirm sales
to any accounts over which they exercise discretionary authority.

    NO PRIOR PUBLIC MARKET.  Prior to this offering, there has been no public
market for the common stock. Consequently, the initial public offering price for
the common stock offered by this prospectus will be determined through
negotiations between us and the representatives. Among the factors to be
considered in these negotiations are prevailing market conditions, our financial
information, market valuations of other companies that we and the
representatives believe to be comparable to us, estimates of our business
potential, the present state of our development and other factors deemed
relevant.

    STABILIZATION.  The representatives have advised us that, under
Regulation M under the Securities Exchange Act, some participants in the
offering may engage in transactions, including stabilizing bids, syndicate
covering transactions or the imposition of penalty bids, that may have the
effect of stabilizing or maintaining the market price of the common stock at a
level above that which might otherwise prevail in the open market. A
"stabilizing bid" is a bid for or the purchase of the common stock on behalf of
the underwriters for the purpose of fixing or maintaining the price of the
common stock. A "syndicate covering transaction" is the bid for or purchase of
the common stock on behalf of the

                                       67
<PAGE>
underwriters to reduce a short position incurred by the underwriters in
connection with the offering. A "penalty bid" is an arrangement permitting the
representatives to reclaim the selling concession otherwise accruing to an
underwriter or syndicate member in connection with the offering if the common
stock originally sold by the underwriter or syndicate member is purchased by the
representatives in a syndicate covering transaction and has therefore not been
effectively placed by the underwriter or syndicate member. The representatives
have advised us that these transactions may be effected on the Nasdaq National
Market or otherwise and, if commenced, may be discontinued at any time.

    OTHER AGREEMENTS.  BancBoston Robertson Stephens acted as placement agent in
connection with the sale of 1,242,000 shares of common stock to Cisco in
September 1999 and was paid customary fees.

    We provide network consulting services to some of the underwriters. Please
see "Certain Transactions--Agreements with Underwriters."

                                 LEGAL MATTERS

    The validity of the common stock offered will be passed upon for us by
Brobeck, Phleger & Harrison LLP, New York, New York. The Brobeck investment fund
and attorneys at Brobeck hold in the aggregate 49,110 shares of series A
preferred stock, which will automatically convert into 49,110 shares of common
stock upon the closing of this offering. Various legal matters in connection
with this offering will be passed upon for the underwriters by Hale and Dorr
LLP, Boston, Massachusetts.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To Predictive Systems, Inc.:


    We have audited the accompanying consolidated balance sheets of Predictive
Systems, Inc. (a Delaware corporation) (the "Company") and subsidiary as of
December 31, 1997 and 1998, and the related consolidated statements of
operations, stockholders' equity and cash flows for each of the three years in
the period ended December 31, 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 Predictive Systems, Inc. and
subsidiary as of December 31, 1997 and 1998, and the results of their operations
and their cash flows for each of the three years in the period ended
December 31, 1998 in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) OWNERSHIP AND OPERATIONS:

    Predictive Systems, Inc. (the "Company"), was incorporated under the laws of
the State of Delaware on February 10, 1995. The Company was formerly 100% owned
by Predictive Holdings, Inc. (the "Parent"). During the first quarter of 1999
the Parent was merged with and into the Company and the Parent was concurrently
dissolved. The financial statements and footnotes reflect the combined
operations and financial position of the Company and the Parent for all periods
presented.

    The Company provides network consulting services for the design,
performance, management and securities of complex computing networks. Services
are currently provided through the Company's offices located throughout the
United States and its wholly-owned subsidiary in England which was formed in the
first quarter of 1999.

    The Company is proposing an initial public offering of up to 4,600,000
shares of common stock including overallotment. See "Risk Factors" in the
accompanying prospectus.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

    UNAUDITED INTERIM FINANCIAL STATEMENTS--

    The accompanying consolidated balance sheet as of June 30, 1999 and
consolidated statements of operations, stockholders' equity and cash flows for
the six months ended June 30, 1998 and 1999 included herein have been prepared
by the Company and are unaudited. The information furnished in the unaudited
financial statements referred to above includes all adjustments which are, in
the opinion of management, necessary for a fair presentation of such financial
statements. The results of operations for the six months ended June 30, 1999 are
not necessarily indicative of the results to be expected for the entire fiscal
year.

    USE OF ESTIMATES--

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

    REVENUE AND COST RECOGNITION--

    Revenue for time-and-material contracts are recognized as the services are
rendered. Revenues for fixed-price contracts are recognized as services are
rendered on the percentage-of-completion method of accounting based on the ratio
of costs incurred to total estimated costs. Unbilled work in process represent
costs incurred and estimated earnings, production, and other client-reimbursable
costs. Included in unbilled work in process as of December 31, 1997 and 1998 and
June 30, 1999 is $39,580, $1,032,390 and $1,448,809 (unaudited), respectively,
related to fixed-price contracts. Provisions for estimated losses on uncompleted
contracts are made in the period in which such losses are determined. The
Company acts as a reseller of certain hardware and software and sales revenue is
recognized when these products are shipped to the customer.

    Deferred income represents prepayments from customers that are recorded as
liabilities for future services to be performed. Income is recognized upon
performance of these related services.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    CASH EQUIVALENTS--

    The Company considers all short-term marketable equity securities with a
maturity of three months or less at the time of purchase to be cash equivalents.

    PROPERTY AND EQUIPMENT--

    Computer equipment and office furniture are carried at their cost basis and
depreciated using the straight-line method over their estimated useful lives,
ranging from three to seven years. Leasehold improvements are amortized over the
lesser of their estimated useful lives or the life of the lease. Expenditures
for maintenance and repairs are charged to operations as incurred and major
expenditures for renewals and betterments are capitalized and depreciated over
their useful lives.

    BUSINESS CONCENTRATIONS AND CREDIT RISK--

    Financial instruments, which subject the Company to concentrations of credit
risk, consist primarily of cash and cash equivalents and trade accounts
receivable. The Company maintains cash and cash equivalents with various
financial institutions. The Company performs periodic evaluations of the
relative credit standing of these institutions. The Company's clients are
primarily concentrated in the United States. The Company performs ongoing credit
evaluations, generally does not require collateral and establishes an allowance
for doubtful accounts based upon factors surrounding the credit risk of
customers, historical trends and other information. To date, such losses have
been within management's expectations.

    For the year ended December 31, 1996, approximately 79% of sales were from
six customers. For the year ended December 31, 1997, approximately 60% of sales
were from four customers. For the year ended December 31, 1998, approximately
20% of sales were from one customer. The amounts due from these customers at
December 31, 1997 and 1998 were approximately $2,357,000 and $2,931,000,
respectively.

    INCOME TAXES--

    The Company accounts for income taxes under Statement of Financial
Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes"
("SFAS 109"). SFAS 109 requires the recognition of deferred tax assets and
liabilities for the expected future tax consequences of events that have been
included in the financial statements or tax returns. Under this method, deferred
tax assets and liabilities are determined based on the differences between the
financial statement and the tax basis of assets and liabilities using enacted
tax rates in effect for the year in which the differences are expected to
reverse. The Company converted from a cash basis to an accrual basis taxpayer on
January 1, 1998.

    UNAUDITED PRO FORMA INFORMATION--

    The Company's historical capital structure is not indicative of its
prospective structure due to the automatic conversion of all shares of its
convertible preferred stock into common stock concurrent with the closing of the
Company's anticipated initial public offering. (See Note 7 for conversion terms)

    The unaudited pro forma consolidated balance sheet as of June 30, 1999,
reflects the conversion of 6,512,316 shares of the convertible preferred stock
into 6,512,316 shares of common stock.

    Pro forma loss per share is computed using the weighted average number of
common shares outstanding during the period assuming conversion of the
convertible preferred stock into common stock as of the date of issuance.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    NET INCOME (LOSS) PER SHARE--

    The Company computes net income (loss) per share in accordance with SFAS
No. 128, "Earnings per Share" ("SFAS 128"). Under the provisions of SFAS 128,
basic net income (loss) per share is computed by dividing net income (loss) by
the weighted average number of shares outstanding. Diluted net income (loss) per
common share ("Diluted EPS") is computed by dividing net income (loss) by the
weighted average number of common shares and dilutive common share equivalents
outstanding.

    ACCOUNTING FOR LONG-LIVED ASSETS--

    The Company accounts for long-lived assets in accordance with the provisions
of SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed Of" ("SFAS 121"). This statement establishes
financial accounting and reporting standards for the impairment of long-lived
assets, certain identifiable intangibles, and goodwill related to those assets
to be held and used, and for long-lived assets and certain identifiable
intangibles to be disposed of. SFAS 121 requires, among other things, that an
entity review its long-lived assets and certain related intangibles for
impairment whenever changes in circumstances indicate that the carrying amount
of an asset may not be fully recoverable. The Company does not believe that any
such changes have taken place.

    STOCK-BASED COMPENSATION--

    In 1996, the Company adopted the provisions of SFAS No. 123 "Accounting for
Stock-Based Compensation" ("SFAS 123"), and elected to continue the accounting
set forth in Accounting Principles Board No. 25 "Accounting for Stock Issued to
Employees" ("APB 25") and to provide the necessary pro forma disclosures as if
the fair value method had been applied (Note 7).

    FAIR VALUE OF FINANCIAL INSTRUMENTS--

    The carrying amounts of cash and cash equivalents, accounts and other
receivables, and accounts payable approximate fair value due to the short-term
maturity of these instruments. The carrying amounts of outstanding borrowings
approximate fair value.

    NEW ACCOUNTING PRONOUNCEMENTS--

    In June 1997, the Financial Accounting Standard Board ("FASB") issued SFAS
No. 131, "Disclosures About Segments of an Enterprise and Related Information."
This statement establishes standards for the way public business enterprises
report information about operating segments in annual financial statements and
requires that those enterprises report selected information about operating
segments in interim financial reports issued to shareholders. This statement is
effective for financial statements for periods beginning after December 15, 1997
and need not be applied to interim periods in the initial year of application.
Comparative information for earlier years presented is to be restated. The
Company does not believe it operates in more than one segment. The chief
operating decision maker allocates resources and assesses the performance
associated with its business on a single-segment basis.

(5) SHORT-TERM BORROWINGS:

    The Company has a secured demand loan under which it may borrow up to
$5,000,000, but not more than 80% of the Company's eligible accounts receivable,
as defined. At December 31, 1998, the balance outstanding on this demand loan
was $5,598,000 as the lender has informally extended the Company's ability to
borrow under this demand loan. The interest rate on the demand loan was 11.25%
at December 31, 1998. During the first quarter of 1999, the balance outstanding
on the demand loan was paid in full.

(7) STOCKHOLDERS' EQUITY:

    PREFERRED STOCK--

    Since inception, the Company has issued two types of preferred stock. The
following is a discussion of each of these issuances--

        In 1995, the Company issued 4,200,000 shares of mandatory redeemable
    convertible preferred stock (the "1995 Preferred Shares") at a price of
    $0.17 per share. The shares accrue dividends at 5% per year, commencing
    March 1, 1997. Each share is convertible, subject to certain adjustments,
    into 1 share of common stock, at the option of the holder. The shares
    automatically convert upon successful completion of an initial public
    offering yielding gross proceeds of at least $10.0 million and at an initial
    public offering price of not less than $0.83 per share. Commencing March 1,
    1998, the Company was able to redeem the 1995 Preferred Shares. Commencing
    March 1, 2001, if not previously redeemed, the Company was required to
    redeem the 1995 Preferred Shares in three equal annual installments.

        During the quarter ended March 31, 1999, the holders of the 1995
    Preferred Shares exercised their conversion rights and converted all
    outstanding shares into 4,200,000 shares of common stock. In connection with
    the conversion, the Company paid $70,000 of accumulated dividends on the
    1995 Preferred Shares.

        Subsequent to the conversion of the 1995 Preferred Shares, the Company
    redeemed 2,855,100 shares of common stock at a purchase price of
    approximately $2.94 per share.

        On March 5, 1999, the Company sold 6,512,316 shares of convertible
    preferred stock (the "1999 Preferred Shares") to General Atlantic Partners
    54, L.P. (5,350,441 shares), GAP Coinvestment Partners II, LP (1,112,765
    shares), and other investors (49,110 shares) resulting in net proceeds of
    approximately $18,600,000. The 1999 Preferred Shares are convertible to
    common shares on a 1 to 1 ratio at any time at the option of the holder,
    subject to certain adjustments. The shares will automatically convert
    (i) prior to the closing of the proposed initial public offering

    yielding net proceeds of at least $25 million and resulting in a market
    capitalization of at least $100 million or (ii) upon the conversion of at
    least 67% of all 1999 Preferred Shares.

        In connection with the issuance of the 1999 Preferred Shares to General
    Atlantic Partners 54, L.P. and GAP Coinvestment Partners II, L.P., warrants
    were issued to purchase shares of common stock equal to 15% of the number of
    shares sold in the proposed initial public offering at a price equal to the
    initial price to the public. In order to exercise the warrants, a notice of
    exercise must be delivered within 20 business days following the first
    filing of the Company's registration statement on Form S-1. (See Note 12)

    STOCK OPTIONS--

    In 1998, the Company adopted its Stock Option/Stock Issuance Plans (the
"Option Plans"). Prior to this time, options issued were not issued in
connection with a plan. The Option Plans are each divided into two separate
equity programs, the Option Grant Program and the Stock Issuance Program. Under
the Option Grant Program, the Company may issue either incentive stock options
or nonqualified stock options. Under the Stock Issuance Program the Company may
issue shares of common stock either through the purchase of such shares or as a
bonus for services rendered. To date, no shares have been issued under the Stock
Issuance Programs. Awards under either program may be granted to such directors,
employees and consultants of the Company as the Board of Directors selects in
its discretion. As of December 31, 1998 a combined total of 2,084,908 shares of
common stock has been reserved for issuance under the two Option Plans.

    A summary of the activity under the Option Grant Programs is as follows--

    The Company has elected to follow APB 25 in accounting for its employee
stock options. Accordingly, no compensation cost has been recognized for Option
Plans. Had the determination of compensation costs been based on the fair value
at the grant dates for awards under the Option Plans, consistent with the method
of SFAS 123, the Company's income (loss) and basic and diluted income (loss) per
share would have been reduced to the following pro forma amounts--

    The fair value of all of our option grants is estimated on the date of grant
using the Black-Scholes model with the following weighted-average assumptions
used for grants in 1996, 1997, 1998 and the six months ended June 30, 1999--

    - weighted-average risk free interest rates of 6.29%, 6.28%, 5.51% and 5.36%
      (unaudited), respectively;

    - expected dividend yields of 0%;

    - expected lives of 4 years; and

    - expected volatility of 0%.

    DEFERRED COMPENSATION--

    During 1999, the Company granted stock options with exercise prices which
were less than the fair market value of the underlying shares of common stock at
the date of grant. As a result, the Company has recorded deferred compensation
of $304,625. This amount will be recognized as noncash compensation expense over
the vesting period of the options (4 years).

    At December 31, 1997 and 1998, the Company had available net operating loss
carryforwards of approximately $580,000 and $390,000 to reduce future period's
taxable income. These loss carryforwards begin to expire in 2012.

    During the six months ended June 30, 1999, the Company's newly formed
subsidiary in England incurred net operating losses, which have been fully
reserved for by a valuation allowance as it cannot be determined that the
realization of these net operating losses is more likely than not.

(9) RELATED PARTIES:

    During 1998, the Company started a software development company which had
previously been consolidated with the Company. In March 1998, the software
development company was spun off through a pro rata distribution to shareholders
accounted for at historical cost. In connection with the spin-off the Company
sold certain assets with minimal book value to the software development company
and received a note for approximately $130,000 for the sale of certain software.
Additionally, the Company provided a $1,000,000 line of credit bearing interest
at 8%. As of December 31, 1998, $916,948 was due from this company.

(10) NOTES RECEIVABLE--STOCKHOLDERS:

    In August 1998, the Company loaned certain stockholders approximately
$515,000 in connection with the exercise of stock options. The stockholders
signed notes payable to the Company in exchange for the loans which had interest
rates of 7%. All amounts due under these notes were paid in full subsequent to
December 31, 1998.

    OPERATING LEASES--

    The Company has entered into non-cancelable operating leases for office
space with terms ranging from approximately six months to five years, with an
option to renew two of these leases for an additional five years. These leases

To Network Resource Consultants and Company B.V.:

    We have audited the accompanying balance sheet of Network Resource
Consultants and Company B.V. (the "Company") as of December 31, 1998, and the
related statements of income, stockholders' (deficit) 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 financial statements referred to above present fairly,
in all material respects, the financial position of Network Resource Consultants
and Company B.V. 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

(1) BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

    BUSINESS-

    Network Resource Consultants and Company B.V. (the "Company" or "NRCC"), is
based in Veenendaal, the Netherlands. The Company is engaged in rendering
services for the design, implementation and operation of network management
systems.

    UNAUDITED INTERIM FINANCIAL STATEMENTS-

    The accompanying balance sheet as of June 30, 1999 and statements of income,
stockholders' (deficit) equity and cash flows for the six months ended June 30,
1998 and 1999 included herein have been prepared by the Company and are
unaudited. The information furnished in the unaudited financial statements
referred to above includes all adjustments which are, in the opinion of
management, necessary for a fair presentation of such financial statements. The
results of operations for the six months ended June 30, 1999 are not necessarily
indicative of the results to be expected for the entire fiscal year.

    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, the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

    REVENUE RECOGNITION-

    Revenues are recognized as services are rendered. Amounts billed to clients
in excess of revenues recognized to date are classified as deferred revenues. In
addition, the Company acts as a reseller of certain hardware and software and
sales revenue is recognized when these products are shipped to the customer.

    FURNITURE, FIXTURES AND EQUIPMENT-

    Furniture, fixtures and equipment are stated at cost, net of accumulated
depreciation and amortization. Furniture and equipment are depreciated on a
straight-line basis over estimated useful lives of three to ten years. Leasehold
improvements are amortized utilizing the straight-line method over the lesser of
the estimated useful life of the asset or the lease term.

    ACCOUNTING FOR LONG-LIVED ASSETS-

    The Company accounts for long-lived assets in accordance with the provisions
of 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." This statement establishes financial accounting and reporting standards for
the impairment of long-lived assets, certain identifiable intangibles, and
goodwill related to those assets to be held and used, and for long-lived assets
and certain identifiable intangibles to be disposed of. SFAS No. 121 require,
among other things, that an entity review its long-lived assets and certain
related intangibles for impairment whenever changes in circumstances

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(1) BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
indicate that the carrying amount of an asset may not be fully recoverable.
Management does not believe that any such changes have taken place.

    INCOME TAXES-

    The Company accounts for income taxes using the asset and liability method.
Under this method, deferred tax assets and liabilities are recognized for the
future tax consequences attributable to differences between the financial
statement carrying amounts of existing assets and liabilities and their tax
basis for operating profit and tax liability carryforward. Deferred tax assets
and liabilities are measured using enacted tax rates expected to apply to
taxable income in the years in which those temporary differences are expected to
be recovered or settled. The effect on deferred tax assets or liabilities of a
change in tax rates is recognized in the period that the tax change occurs.

    COMPREHENSIVE INCOME-

    During 1998, the Company adopted SFAS No. 130 "Reporting Comprehensive
Income", which establishes standards for reporting and displaying comprehensive
income and its components in a financial statement that is displayed with the
same prominence as other financial statements. The components of comprehensive
income relate to foreign currency translation adjustments.

    FOREIGN CURRENCY TRANSLATION-

    All assets and liabilities of the Company are translated into U.S. dollars
at fiscal year-end exchange rates. Income and expense items are translated at
average exchange rates prevailing during the fiscal year. The resulting
translation adjustments are recorded as a component of stockholders' (deficit)
equity in the accompanying financial statements.

    FAIR VALUE OF FINANCIAL INSTRUMENTS-

    The carrying amounts of cash, accounts receivable and accounts payable
approximate fair value due to the short-term maturity of these instruments.

(2) RELATED PARTY TRANSACTIONS:

    As of December 31, 1998 and June 30, 1999, the Company had $322,712 and
$269,150 (unaudited) outstanding to one of the Company's stockholders. The
interest rate on the loan was 6%. Subsequent to June 30, 1999, the loan was
settled in full.

        UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


    The following unaudited pro forma condensed consolidated financial
statements for the six months ended June 30, 1999 and the fiscal year ended
December 31, 1998 have been derived from the application of pro forma
adjustments to the historical financial statements of Predictive Systems, Inc.
("Predictive") and Network Resource Consultants and Company B.V. ("NRCC"),
included elsewhere in this prospectus. The unaudited pro forma condensed
consolidated statement of operations information for the six months ended
June 30, 1999 and for the year ended December 31, 1998, gives effect to the
acquisition as if it had occurred on January 1, 1998. The unaudited pro forma
condensed consolidated balance sheet gives effect to the acquisition of NRCC as
if it had occurred on June 30, 1999.


    The unaudited pro forma condensed consolidated financial statements do not
necessarily reflect what our actual financial results would have been had the
acquisition been completed on these dates, nor does it purport to be indicative
of future financial results.

    The acquisition has been 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 the purchase price over the fair value of the net
assets acquired was approximately $4.3 million.

                          NOTES TO UNAUDITED PRO FORMA
                  CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


    The unaudited pro forma condensed consolidated statements of operations have
been prepared to reflect the acquisition of NRCC as if this acquisition occurred
on January 1, 1998. The unaudited pro forma condensed consolidated balance sheet
was prepared to reflect the acquisition as of June 30, 1999. NRCC's historical
financial statements were derived from its books and records and reflect:


    - the statement of operations of NRCC for the six month period from
      January 1, 1999 to June 30, 1999;

    - the statement of operations of NRCC for the 12 month period ended
      December 31, 1998; and

    - the balance sheet of NRCC as of June 30, 1999.

The acquisition has been accounted for under the purchase method of accounting.

    The following is a summary of the adjustments reflected in the unaudited pro
forma condensed consolidated statements of operations:

        1. Represents the amortization of the excess of the purchase price over
    the net assets of NRCC acquired.

        2. Represents the increase in the number of outstanding shares of common
    stock to reflect the 1,062,814 shares issued to the stockholders of NRCC to
    fund the purchase price.

    The following is a summary of the adjustments reflected in the unaudited pro
forma condensed consolidated balance sheet:

        3. Represents the preliminary estimates of the excess purchase price
    over the net assets acquired as follows--

<TABLE>
<S>                                                           <C>
Purchase price (including $100,000 of transaction
  expenses).................................................  $4,351,256
Net tangible assets acquired................................      87,719
                                                              ----------
Excess of purchase price over net tangible assets
  acquired..................................................  $4,263,537
                                                              ==========
</TABLE>

    Predictive believes that all significant assets and liabilities have been
identified and, accordingly, that the final determination of the allocation of
the NRCC purchase price should not vary materially from the preliminary
estimate. Predictive anticipates finalizing the purchase price allocation upon
completing the preparation and review of the August 12, 1999 (acquisition date)
financial statements of NRCC.


    The identifiable assets are being amortized over their estimated useful
lives. Intangible assets resulting from the excess of the purchase price over
the fair value of the net assets acquired, including workforce, customer lists
and goodwill, are being amortized over a period of 5 years.



    Subsequent to the acquisition, Predictive will review the carrying values
assigned to the intangible assets to determine whether later events or
circumstances have occurred that indicate that the balance of the intangible
assets may be impaired. Predictive's principal considerations in determining the
impairment of the intangible assets will include the strategic benefit to
Predictive of the particular business as measured by expected undiscounted
future cash flows. Predictive is not aware of any events or circumstances which
would impair the intangible assets.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    The Registrant's Amended and Restated Certificate of Incorporation in effect
as of the date hereof (the "Certificate") provides that, except to the extent
prohibited by the Delaware General Corporation Law, as amended (the "DGCL"), the
Registrant's directors shall not be personally liable to the Registrant or its
stockholders for monetary damages for any breach of fiduciary duty as directors
of the Registrant. Under the DGCL, the directors have a fiduciary duty to the
Registrant which is not eliminated by this provision of the Certificate and, in
appropriate circumstances, equitable remedies such as injunctive or other forms
of nonmonetary relief will remain available. In addition, each director will
continue to be subject to liability under the DGCL for breach of the director's
duty of loyalty to the Registrant, for acts or omissions which are found by a
court of competent jurisdiction to be not in good faith or involving intentional
misconduct, for knowing violations of law, for actions leading to improper
personal benefit to the director, and for payment of dividends or approval of
stock repurchases or redemptions that are prohibited by the DGCL. This provision
also does not affect the directors' responsibilities under any other laws, such
as the Federal securities laws or state or Federal environmental laws. The
Registrant has applied for liability insurance for its officers and directors.

    Section 145 of the DGCL empowers a corporation to indemnify its directors
and officers and to purchase insurance with respect to liability arising out of
their capacity or status as directors and officers, provided that this provision
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) arising under Section 174 of the DGCL, or
(iv) for any transaction from which the director derived an improper personal
benefit. The DGCL provides further that the indemnification permitted thereunder
shall not be deemed exclusive of any other rights to which the directors and
officers may be entitled under the corporation's bylaws, any agreement, a vote
of stockholders or otherwise. The Certificate eliminates the personal liability
of directors to the fullest extent permitted by Section 102(b)(7) of the DGCL
and provides that the Registrant may fully indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding

                                      II-1
<PAGE>
(whether civil, criminal, administrative or investigative) by reason of the fact
that such person is or was a director or officer of the Registrant, or is or was
serving at the request of the Registrant as a director or officer of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, against expenses (including attorney's fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding.

    At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under the Certificate. The Registrant is not aware of any
threatened litigation or proceeding that may result in a claim for such
indemnification.

ITEM 17. UNDERTAKINGS

    The undersigned Registrant hereby undertakes 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 prompt delivery to each purchaser.

    The undersigned Registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act of 1933,
    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 424 (b)(1) or (4), or
    497(h) under the Securities Act of 1933, shall be deemed to be part of this
    registration statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act of
    1933, 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 this offering of such securities at that time shall be
    deemed to be the initial BONA FIDE offering thereof.

                                      II-4
<PAGE>
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act, and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of 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.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Predictive Systems, Inc.

    We have audited in accordance with generally accepted auditing standards,
the financial statements of Predictive Systems, Inc. included in this
registration statement and have issued our report thereon dated May 12, 1999.
Our audit was made for the purpose of forming an opinion on the basic financial
statements taken as a whole. The schedule of valuation and qualifying accounts
is the responsibility of the Company's management and is presented for purposes
of complying with the Securities and Exchange Commissions rules and is 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.

BancBoston Robertson Stephens Inc.
Bear, Stearns & Co. Inc.
Donaldson, Lufkin & Jenrette
First Union Capital Markets
   As Representatives of the several Underwriters
c/o BancBoston Robertson Stephens Inc.
555 California Street, Suite 2600
San Francisco, CA  94104


Ladies and Gentlemen:

         INTRODUCTORY. Predictive Systems, Inc., a Delaware corporation (the
"Company"), proposes to issue and sell to the several underwriters named in
SCHEDULE A (the "Underwriters") an aggregate of 4,000,000 shares (the "Firm
Shares") of its Common Stock, par value $.001 per share (the "Common Shares").
In addition, the Company has granted to the Underwriters an option to purchase
up to an additional 600,000 Common Shares (the "Option Shares") as provided in
Section 2. The Firm Shares and, if and to the extent such option is exercised,
the Option Shares are collectively called the "Shares". BancBoston Robertson
Stephens Inc., Bear, Stearns & Co. Inc., Donaldson, Lufkin & Jenrette and First
Union Capital Markets have agreed to act as representatives of the several
Underwriters (in such capacity, the "Representatives") in connection with the
offering and sale of the Shares.

         The Company has prepared and filed with the Securities and Exchange
Commission (the "Commission") a registration statement on Form S-1 (File No.
333-84045), which contains a form of prospectus to be used in connection with
the public offering and sale of the Shares. Such registration statement, as
amended, including the financial statements, exhibits and schedules thereto, in
the form in which it was declared effective by the Commission under the
Securities Act of 1933 and the rules and regulations promulgated thereunder
(collectively, the "Securities Act"), including any information deemed to be a
part thereof at the time of effectiveness pursuant to Rule 430A or Rule 434
under the Securities Act, is called the "Registration Statement." Any
registration statement filed by the Company pursuant to Rule 462(b) under the
Securities Act is called the "Rule 462(b) Registration Statement", and


<PAGE>

from and after the date and time of filing of the Rule 462(b) Registration
Statement the term "Registration Statement" shall include the Rule 462(b)
Registration Statement. Such prospectus, in the form first used by the
Underwriters to confirm sales of the Shares, is called the "Prospectus";
provided, however, if the Company has, with the consent of BancBoston Robertson
Stephens Inc., elected to rely upon Rule 434 under the Securities Act, the term
"Prospectus" shall mean the Company's prospectus subject to completion (each, a
"preliminary prospectus") dated September __, 1999 (such preliminary prospectus
is called the "Rule 434 preliminary prospectus"), together with the applicable
term sheet (the "Term Sheet") prepared and filed by the Company with the
Commission under Rules 434 and 424(b) under the Securities Act and all
references in this Agreement to the date of the Prospectus shall mean the date
of the Term Sheet. All references in this Agreement to the Registration
Statement, the Rule 462(b) Registration Statement, a preliminary prospectus, the
Prospectus or the Term Sheet, or any amendments or supplements to any of the
foregoing, shall include any copy thereof filed with the Commission pursuant to
its Electronic Data Gathering, Analysis and Retrieval System ("EDGAR").

         The Company hereby confirms its agreements with the Underwriters as
follows:

         SECTION 1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         The Company hereby represents, warrants and covenants to each
Underwriter as follows:

         (a) COMPLIANCE WITH REGISTRATION REQUIREMENTS. The Registration
Statement and any Rule 462(b) Registration Statement have been declared
effective by the Commission under the Securities Act. The Company has complied
to the Commission's satisfaction with all requests of the Commission for
additional or supplemental information. No stop order suspending the
effectiveness of the Registration Statement or any Rule 462(b) Registration
Statement is in effect and no proceedings for such purpose have been instituted
or are pending or, to the best knowledge of the Company, are contemplated or
threatened by the Commission.

         Each preliminary prospectus and the Prospectus when filed complied in
all material respects with the Securities Act and, if filed by electronic
transmission pursuant to EDGAR (except as may be permitted by Regulation S-T
under the Securities Act), was identical to the copy thereof delivered to the
Underwriters for use in connection with the offer and sale of the Shares. Each
of the Registration Statement, any Rule 462(b) Registration Statement and any
post-effective amendment thereto, at the time it became effective and at all
subsequent times, complied and will comply in all material respects with the
Securities Act and did not and will not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading. The Prospectus, as
amended or supplemented, as of its date and at all subsequent times, did not and
will not contain any untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading. The
representations and warranties set forth in the two immediately preceding
sentences do not apply to statements in or omissions from the Registration
Statement,


                                      -2-
<PAGE>

any Rule 462(b) Registration Statement, or any post-effective amendment thereto,
or the Prospectus, or any amendments or supplements thereto, made in reliance
upon and in conformity with information relating to any Underwriter furnished to
the Company in writing by the Representative expressly for use therein. There
are no contracts or other documents required to be described in the Prospectus
or to be filed as exhibits to the Registration Statement which have not been
described or filed as required.

         (b) OFFERING MATERIALS FURNISHED TO UNDERWRITERS. The Company has
delivered to the Representative four complete conformed copies of the
Registration Statement and of each consent and certificate of experts filed as a
part thereof, and conformed copies of the Registration Statement (without

in a material adverse change, in the condition, financial or otherwise, or in
the earnings, business, operations or prospects, whether or not arising from

accountants as required by the Securities Act.

         (i) PREPARATION OF THE FINANCIAL STATEMENTS. The financial statements
filed with the Commission as a part of the Registration Statement and included

Company and its subsidiaries as of and at the dates indicated and the results of
their operations and cash flows for the periods specified. The supporting

supporting schedules have been prepared in conformity with generally accepted
accounting principles as applied in the United States on a consistent basis
throughout the periods involved, except as may be expressly stated in the
related notes thereto. No other financial statements or supporting schedules are
required to be included in the Registration Statement. The financial data set
forth in the Prospectus under the captions "Prospectus Summary--Summary Selected
Financial Data", "Selected Financial Data" and "Capitalization" fairly present
the information set forth therein on a basis consistent with that of the audited
financial statements contained in the Registration Statement.

         (j) COMPANY'S ACCOUNTING SYSTEM. The Company and each of its
subsidiaries maintain a system of accounting controls sufficient to provide
reasonable assurances that (i) transactions are executed in accordance with
management's general or specific authorization; (ii) transactions are recorded
as necessary to permit preparation of financial statements in conformity with
generally accepted accounting principles as applied in the United States and to
maintain accountability for assets; (iii) access to assets is permitted only in
accordance with management's general or specific authorization; and (iv) the
recorded accountability for assets is compared with existing assets at
reasonable intervals and appropriate action is taken with respect to any
differences.

         (k) SUBSIDIARIES OF THE COMPANY. The Company does not own or control,
directly or indirectly, any corporation, association or other entity other than
the subsidiaries listed in Exhibit 21 to the Registration Statement.

SUBSIDIARIES. Each of


                                      -4-

the Company and its subsidiaries has been duly organized and is validly existing
as a corporation or limited liability company, as the case may be, in good
standing under the laws of the jurisdiction in which it is organized with full
corporate power and authority to own its properties and conduct its business as
described in the prospectus, and is duly qualified to do business as a foreign
corporation and is in good standing under the laws of each jurisdiction which
requires such qualification.

         (m) CAPITALIZATION OF THE SUBSIDIARIES. All the outstanding shares of
capital stock of each subsidiary have been duly and validly authorized and
issued and are fully paid and nonassessable, and, except as otherwise set forth
in the Prospectus, all outstanding shares of capital stock of the subsidiaries
are owned by the Company either directly or through wholly owned subsidiaries
free and clear of any security interests, claims, liens or encumbrances.

         (n) NO PROHIBITION ON SUBSIDIARIES FROM PAYING DIVIDENDS OR MAKING
OTHER DISTRIBUTIONS. No subsidiary of the Company is currently prohibited,
directly or indirectly, from paying any dividends to the Company, from making
any other distribution on such subsidiary's capital stock, from repaying to the
Company any loans or advances to such subsidiary from the Company or from
transferring any of such subsidiary's property or assets to the Company or any
other subsidiary of the Company, except as described in or contemplated by the
Prospectus.

         (o) CAPITALIZATION AND OTHER CAPITAL STOCK MATTERS. The authorized,
issued and outstanding capital stock of the Company is as set forth in the
Prospectus under the caption "Capitalization" (other than for subsequent
issuances, if any, pursuant to employee benefit plans described in the
Prospectus or upon exercise of outstanding options or warrants, if any,
described in the Prospectus). The Common Shares (including the Shares) conform
in all material respects to the description thereof contained in the Prospectus.
All of the issued and outstanding Common Shares have been duly authorized and
validly issued, are fully paid and nonassessable and have been issued in
compliance with federal and state securities laws. None of the outstanding
Common Shares were issued in violation of any preemptive rights, rights of first
refusal or other similar rights to subscribe for or purchase securities of the
Company. There are no authorized or outstanding options, warrants, preemptive
rights, rights of first refusal or other rights to purchase, or equity or debt
securities convertible into or exchangeable or exercisable for, any capital
stock of the Company or any of its subsidiaries other than those accurately
described in the Prospectus. The description of the Company's stock option,
stock bonus and other stock plans or arrangements, and the options or other
rights granted thereunder, set forth in the Prospectus accurately and fairly
presents the information required to be shown with respect to such plans,
arrangements, options and rights.

         (p) STOCK EXCHANGE LISTING. The Shares have been approved for listing
on the Nasdaq National Market, subject only to official notice of issuance.

         (q) NO CONSENTS, APPROVALS OR AUTHORIZATIONS REQUIRED. No consent,

agency or regulatory body is required in connection with the transactions
contemplated herein, except such as have been


                                      -5-

the blue sky laws of any jurisdiction in connection with the purchase and
distribution of the Shares by the Underwriters in the manner contemplated here
and in the Prospectus, (ii) by the National Association of Securities Dealers,
LLC and (iii) by the federal and provincial laws of Canada.

         (r) NON-CONTRAVENTION OF EXISTING INSTRUMENTS AGREEMENTS. Neither the
issue and sale of the Shares nor the consummation of any other of the
transactions herein contemplated nor the fulfillment of the terms hereof will
conflict with, result in a breach or violation or imposition of any lien, charge
or encumbrance upon any property or assets of the Company or any of its
subsidiaries pursuant to, (i) the charter or by-laws of the Company or any of
its subsidiaries, (ii) the terms of any indenture, contract, lease, mortgage,
deed of trust, note agreement, loan agreement or other agreement, obligation,
condition, covenant or instrument to which the Company or any of its
subsidiaries is a party or bound or to which its or their property is subject or
(iii) any statute, law, rule, regulation, judgment, order or decree applicable
to the Company or any of its subsidiaries of any court, regulatory body,
administrative agency, governmental body, arbitrator or other authority having
jurisdiction over the Company or any of its subsidiaries or any of its or their
properties.

         (s) NO DEFAULTS OR VIOLATIONS. Neither the Company nor any subsidiary
is in violation or default of (i) any provision of its charter or by-laws, (ii)
the terms of any indenture, contract, lease, mortgage, deed of trust, note
agreement, loan agreement or other agreement, obligation, condition, covenant or
instrument to which it is a party or bound or to which its property is subject
or (iii) any statute, law, rule, regulation, judgment, order or decree of any
court, regulatory body, administrative agency, governmental body, arbitrator or
other authority having jurisdiction over the Company or such subsidiary or any
of its properties, as applicable, except any such violation or default which
would not, singly or in the aggregate, result in a Material Adverse Change
except as otherwise disclosed in the Prospectus.

         (t) NO ACTIONS, SUITS OR PROCEEDINGS. No action, suit or proceeding by
or before any court or governmental agency, authority or body or any arbitrator
involving the Company or any of its subsidiaries or its or their property is
pending or, to the best knowledge of the Company, threatened that (i) could
reasonably be expected to have a Material Adverse Effect on the performance of
this Agreement or the consummation of any of the transactions contemplated
hereby or (ii) could reasonably be expected to result in a Material Adverse
Effect.

         (u) ALL NECESSARY PERMITS, ETC. The Company and each subsidiary possess
such valid and current certificates, authorizations or permits issued by the
appropriate state, federal or foreign regulatory agencies or bodies necessary to
conduct their respective businesses, and neither the Company nor any subsidiary
has received any notice of proceedings relating to the revocation or
modification of, or non-compliance with, any such certificate, authorization or
permit which, singly or in the aggregate, if the subject of an unfavorable
decision, ruling or finding, could result in a Material Adverse Change.

         (v) TITLE TO PROPERTIES. The Company and each of its subsidiaries has
good and marketable title to all the properties and assets reflected as owned in
the financial statements


                                      -6-
<PAGE>

referred to in Section 1(i) above (or elsewhere in the Prospectus), in each case
free and clear of any security interests, mortgages, liens, encumbrances,
equities, claims and other defects, except such as do not materially and
adversely affect the value of such property and do not materially interfere with
the use made or proposed to be made of such property by the Company or such
subsidiary. The real property, improvements, equipment and personal property
held under lease by the Company or any subsidiary are held under valid and
enforceable leases, with such exceptions as are not material and do not
materially interfere with the use made or proposed to be made of such real
property, improvements, equipment or personal property by the Company or such
subsidiary.

         (w) TAX LAW COMPLIANCE. The Company and its consolidated subsidiaries
have filed all necessary federal, state and foreign income and franchise tax
returns or have properly requested extensions thereof and have paid all taxes
required to be paid by any of them and, if due and payable, any related or
similar assessment, fine or penalty levied against any of them. The Company has
made adequate charges, accruals and reserves in the applicable financial
statements referred to in Section 1(i) above in respect of all federal, state
and foreign income and franchise taxes for all periods as to which the tax
liability of the Company or any of its consolidated subsidiaries has not been
finally determined. The Company is not aware of any tax deficiency that has been
or might be asserted or threatened against the Company that could result in a
Material Adverse Change.

         (x) INTELLECTUAL PROPERTY RIGHTS. Each of the Company and its
subsidiaries owns or possesses adequate rights to use all patents, patent rights
or licenses, inventions, collaborative research agreements, trade secrets,
know-how, trademarks, service marks, trade names and copyrights which are
necessary to conduct its businesses as described in the Registration Statement
and Prospectus; the expiration of any patents, patent rights, trade secrets,
trademarks, service marks, trade names or copyrights would not result in a
Material Adverse Change that is not otherwise disclosed in the Prospectus; the
Company has not received any notice of, and has no knowledge of, any
infringement of or conflict with asserted rights of the Company by others with
respect to any patent, patent rights, inventions, trade secrets, know-how,
trademarks, service marks, trade names or copyrights; and the Company has not
received any notice of, and has no knowledge of, any infringement of or conflict
with asserted rights of others with respect to any patent, patent rights,
inventions, trade secrets, know-how, trademarks, service marks, trade names or
copyrights which, singly or in the aggregate, if the subject of an unfavorable
decision, ruling or finding, might have a Material Adverse Change. There is no
claim being made against the Company regarding patents, patent rights or
licenses, inventions, collaborative research, trade secrets, know-how,
trademarks, service marks, trade names or copyrights. The Company and its
subsidiaries do not in the conduct of their business as now or proposed to be
conducted as described in the Prospectus infringe or conflict with any right or
patent of any third party, or any discovery, invention, product or process which
is the subject of a patent application filed by any third party, known to the
Company or any of its subsidiaries, which such infringement or conflict is
reasonably likely to result in a Material Adverse Change.

         (y) YEAR 2000 PREPAREDNESS. There are no issues related to the
Company's, or any of its subsidiaries', preparedness for the Year 2000 that (i)
are of a character required to be


                                      -7-
<PAGE>

described or referred to in the Registration Statement or Prospectus by the
Securities Act or the rules and regulations of the Commission thereunder which
have not been accurately described in the Registration Statement or Prospectus
or (ii) might reasonably be expected to result in any Material Adverse Change or
that might materially affect their properties, assets or rights. All internal
computer systems and each Constituent Component (as defined below) of those
systems and all computer-related products and each Constituent Component (as
defined below) of those products of the Company and each of its subsidiaries
fully comply with Year 2000 Qualification Requirements. "Year 2000
Qualifications Requirements" means that the internal computer systems and each
Constituent Component (as defined below) of those systems and all
computer-related products and each Constituent Component (as defined below) of
those products of the Company and each of its Subsidiaries (i) have been
reviewed to confirm that they store, process (including sorting and performing
mathematical operations, calculations and computations), input and output data
containing date and information correctly regardless of whether the date
contains dates and times before, on or after January 1, 2000, (ii) have been
designated to ensure date and time entry recognition and calculations, and date
data interface values that reflect the century, (iii) accurately manage and
manipulate data involving dates and times, including single century formulas and
multi-century formulas, and will not cause an abnormal ending scenario within
the application or generate incorrect values or invalid results involving such
dates, (iv) accurately process any date rollover, and (v) accept and respond to
two-digit year date input in a manner that resolves any ambiguities as to the
century. "Constituent Component" means all software (including operating
systems, programs, packages and utilities), firmware, hardware, networking
components, and peripherals provided as part of the configuration. The Company
has inquired of material vendors as to their preparedness for the Year 2000 and
has disclosed in the Registration Statement or Prospectus any issues that might
reasonably be expected to result in any Material Adverse Change.

         (z) NO TRANSFER TAXES OR OTHER FEES. There are no transfer taxes or
other similar fees or charges under Federal law or the laws of any state, or any
political subdivision thereof, required to be paid in connection with the
execution and delivery of this Agreement or the issuance and sale by the Company
of the shares.

         (aa) COMPANY NOT AN "INVESTMENT COMPANY". The Company has been advised
of the rules and requirements under the Investment Company Act of 1940, as
amended (the "Investment Company Act"). The Company is not, and after receipt of
payment for the Shares will not be, an "investment company" or an entity
"controlled" by an "investment company" within the meaning of the Investment
Company Act and will conduct its business in a manner so that it will not become
subject to the Investment Company Act.

         (bb) INSURANCE. Each of the Company and its subsidiaries are insured by
recognized, financially sound and reputable institutions with policies in such
amounts and with such deductibles and covering such risks as are generally
deemed adequate and customary for their businesses including, but not limited
to, policies covering real and personal property owned or leased by the Company
and its subsidiaries against theft, damage, destruction, acts of vandalism and
earthquakes, general liability and Directors and Officers liability. The Company
has no


                                      -8-
<PAGE>

reason to believe that it or any subsidiary will not be able (i) to renew its
existing insurance coverage as and when such policies expire or (ii) to obtain
comparable coverage from similar institutions as may be necessary or appropriate
to conduct its business as now conducted and at a cost that would not result in
a Material Adverse Change. Neither of the Company nor any subsidiary has been
denied any insurance coverage which it has sought or for which it has applied.

         (cc) LABOR MATTERS. To the best of Company's knowledge, no labor
disturbance by the employees of the Company or any of its subsidiaries exists or
is imminent; and the Company is not aware of any existing or imminent labor
disturbance by the employees of any of its principal suppliers, subassemblers,
value added resellers, subcontractors, original equipment manufacturers,
authorized dealers or international distributors, as applicable, that might be
expected to result in a Material Adverse Change.

         (dd) NO PRICE STABILIZATION OR MANIPULATION. The Company has not taken
and will not take, directly or indirectly, any action designed to or that might
be reasonably expected to cause or result in stabilization or manipulation of
the price of the Common Stock to facilitate the sale or resale of the Shares.

         (ee) LOCK-UP AGREEMENTS. Each officer and director of the company and
each beneficial owner of one or more percent of the outstanding issued share
capital of the Company has agreed to sign an agreement substantially in the form
attached hereto as EXHIBIT A (the "Lock-up Agreements"). The Company has
provided to counsel for the Underwriters a complete and accurate list of all
securityholders of the Company and the number and type of securities held by
each securityholder. The Company has provided to counsel for the Underwriters
true, accurate and complete copies of all of the Lock-up Agreements presently in
effect or effected hereby. The Company hereby represents and warrants that it
will not release any of its officers, directors or other stockholders from any
Lock-up Agreements currently existing or hereafter effected without the prior
written consent of BancBoston Robertson Stephens Inc.

         (ff) RELATED PARTY TRANSACTIONS. There are no business relationships or
related-party transactions involving the Company or any subsidiary or any other
person required to be described in the Prospectus which have not been described
as required.

                  Any certificate signed by an officer of the Company and
delivered to the Representative or to counsel for the Underwriters shall be
deemed to be a representation and warranty by the Company to each Underwriter as
to the matters set forth therein.

         (gg) NO UNLAWFUL CONTRIBUTIONS OR OTHER PAYMENTS. Neither the Company
nor any of its subsidiaries nor, to the best of the Company's knowledge, any
employee or agent of the Company or any subsidiary, has made any contribution or
other payment to any official of, or candidate for, any federal, state or
foreign office in violation of any law or of the character required to be
disclosed in the Prospectus.


                                      -9-
<PAGE>

         (hh) ENVIRONMENTAL LAWS. The Company is in compliance with all rules,
laws and regulations relating to the use, treatment, storage and disposal of
toxic substances and protection of health or the environment ("Environmental
Laws") which are applicable to its business, except where the failure to comply
would not result in a Material Adverse Change. The Company has received no
notice from any governmental authority or third party of an asserted claim under
Environmental Laws, which claim is required to be disclosed in the Registration
Statement and the Prospectus. The Company will not be required to make future
material capital expenditures to comply with Environmental Laws and no property
which is owned, leased or occupied by the Company has been designated as a
Superfund site pursuant to the Comprehensive Response, Compensation, and
Liability Act of 1980, as amended (42 U.S.C. ss. 9601, eT Seq.), or otherwise
designated as a contaminated site under applicable state or local law.

         (ii) PERIODIC REVIEW OF COSTS OF ENVIRONMENTAL COMPLIANCE. In the
ordinary course of its business, the Company conducts a periodic review of the
effect of Environmental Laws on the business, operations and properties of the
Company and its subsidiaries, in the course of which it identifies and evaluates
associated costs and liabilities (including, without limitation, any capital or
operating expenditures required for clean-up, closure of properties or
compliance with Environmental Laws or any permit, license or approval, any
related constraints on operating activities and any potential liabilities to
third parties). On the basis of such review and the amount of its established
reserves, the Company has reasonably concluded that such associated costs and
liabilities would not, individually or in the aggregate, result in a Material
Adverse Change.

         (jj) ERISA COMPLIANCE. The Company and its subsidiaries and any
"employee benefit plan" (as defined under the Employee Retirement Income
Security Act of 1974, as amended, and the regulations and published
interpretations thereunder (collectively, "ERISA")) established or maintained by
the Company, its subsidiaries or their "ERISA Affiliates" (as defined below) are
in compliance in all material respects with ERISA. "ERISA Affiliates" means,
with respect to the Company or a subsidiary, any member of any group of
organizations described in Sections 414(b),(c),(m) or (o) of the Internal
Revenue Code of 1986, as amended, and the regulations and published
interpretations thereunder (the "Code") of which the Company or such subsidiary
is a member. No "reportable event" (as defined under ERISA) has occurred or is
reasonably expected to occur with respect to any "employee benefit plan"
established or maintained by the Company, its subsidiaries or any of their ERISA
Affiliates. No "employee benefit plan" established or maintained by the Company,
its subsidiaries or any of their ERISA Affiliates, if such "employee benefit
plan" were terminated, would have any "amount of unfounded benefit liabilities"
(as defined under ERISA). Neither the Company, its subsidiaries nor any of their
ERISA Affiliates has incurred or reasonably expects to incur any liability under
(i) Title IV of ERISA with respect to termination of, or withdrawal from, any
"employee benefit plan" or (ii) Sections 412, 4971, 4975 or 4980B of the Code.
Each "employee benefit plan" established or maintained by the Company, its
subsidiaries or any of their ERISA Affiliates that is intended to be qualified
under Section 401(a) of the Code is so qualified and nothing has occurred,
whether by action or failure to act, which would cause the loss of such
qualification.

         SECTION 2. PURCHASE, SALE AND DELIVERY OF THE SHARES.

         (a) THE FIRM SHARES. The Company agrees to issue and sell to the
several Underwriters the Firm Shares upon the terms herein set forth. On the
basis of the representations, warranties and agreements herein contained, and
upon the terms but subject to the conditions herein set forth, the Underwriters
agree, severally and not jointly, to purchase from the Company the respective
number of Firm Shares set forth opposite their names on SCHEDULE A. The purchase
price per Firm Share to be paid by the several Underwriters to the Company shall
be $[___] per share.

         (b) THE FIRST CLOSING DATE. Delivery of the Firm Shares to be purchased
by the Underwriters and payment therefor shall be made by the Company and the
Representative at 9:00 a.m. Boston time, at the offices of Hale and Dorr LLP, 60
State Street, Boston, MA 02109 (or at such other place as may be agreed upon
among the Representatives and the Company), (i) on the third (3rd) full business
day following the first day that Shares are traded, (ii) if this Agreement is
executed and delivered after 4:30 p.m., Boston time, the fourth (4th) full
business day following the day that this Agreement is executed and delivered or
(iii) at such other time and date not later that seven (7) full business days
following the first day that Shares are traded as the Representative and the
Company may determine (or at such time and date to which payment and delivery
shall have been postponed pursuant to Section 8 hereof), such time and date of
payment and delivery being herein called the "Closing Date;" provided, however,
that if the Company has not made available to the Representatives copies of the
Prospectus within the time provided in Section 4(d) hereof, the Representative
may, in its sole discretion, postpone the Closing Date until no later that two
(2) full business days following delivery of copies of the Prospectus to the
Representative.

         (c) THE OPTION SHARES; THE SECOND CLOSING DATE. In addition, on the
basis of the representations, warranties and agreements herein contained, and
upon the terms but subject to the conditions herein set forth, the Company
hereby grants an option to the several Underwriters to purchase, severally and
not jointly, up to an aggregate of 600,000 Option Shares from the Company at the
purchase price per share to be paid by the Underwriters for the Firm Shares. The
option granted hereunder is for use by the Underwriters solely in covering any
over-allotments in connection with the sale and distribution of the Firm Shares.
The option granted hereunder may be exercised at any time upon notice by the
Representative to the Company, which notice may be given at any time within 30
days from the date of this Agreement. The time and date of delivery of the
Option Shares, if subsequent to the First Closing Date, is called the "Second
Closing Date" and shall be determined by the Representative and shall not be
earlier than three nor later than five full business days after delivery of such
notice of exercise. If any Option Shares are to be purchased, each Underwriter
agrees, severally and not jointly, to purchase the number of Option Shares
(subject to such adjustments to eliminate fractional shares as the
Representative may determine) that bears the same proportion to the total number
of Option Shares to be purchased as the number of Firm Shares set forth on
SCHEDULE A opposite the name of such Underwriter bears to the total number of
Firm Shares and the Company agrees, to sell the number of Option


                                      -11-
<PAGE>

Shares (subject to such adjustments to eliminate fractional shares as the
Representative may determine) as the number of Option Shares to be sold by the
Company as set forth in the paragraph "Introductory" of this Agreement) bears to
the total number of Option Shares. The Representative may cancel the option at
any time prior to its expiration by giving written notice of such cancellation
to the Company.

         (d) PUBLIC OFFERING OF THE SHARES. The Representative hereby advises
the Company that the Underwriters intend to offer for sale to the public, as
described in the Prospectus, their respective portions of the Shares as soon
after this Agreement has been executed and the Registration Statement has been
declared effective as the Representative, in its sole judgment, has determined
is advisable and practicable.

         (e) PAYMENT FOR THE SHARES. Payment for the Shares shall be made at the
First Closing Date (and, if applicable, at the Second Closing Date) by wire
transfer in immediately availablefunds to the order of the Company.

                  It is understood that the Representative has been authorized,
for its own account and the accounts of the several Underwriters, to accept
delivery of and receipt for, and make payment of the purchase price for, the
Firm Shares and any Option Shares the Underwriters have agreed to purchase.
BancBoston Robertson Stephens Inc., individually and not as the Representative
of the Underwriters, may (but shall not be obligated to) make payment for any
Shares to be purchased by any Underwriter whose funds shall not have been
received by the Representative by the First Closing Date or the Second Closing
Date, as the case may be, for the account of such Underwriter, but any such
payment shall not relieve such Underwriter from any of its obligations under
this Agreement.

         (f) DELIVERY OF THE SHARES. The Company shall deliver, or cause to be
delivered, a credit representing the Firm Shares to an account or accounts at
The Depository Trust Company, as designated by the Representative for the
accounts of the Representative and the several Underwriters at the First Closing
Date, against the irrevocable release of a wire transfer of immediately
available funds for the amount of the purchase price therefor. The Company shall
also deliver, or cause to be delivered a credit representing the Option Shares
the Underwriters have agreed to purchase at the First Closing Date (or the
Second Closing Date, as the case may be), to an account or accounts at The
Depository Trust Company as designated by the Representatives for the accounts
of the Representative and the several Underwriters, against the irrevocable
release of a wire transfer of immediately available funds for the amount of the
purchase price therefor. Time shall be of the essence, and delivery at the time
and place specified in this Agreement is a further condition to the obligations
of the Underwriters.

         SECTION 3. COVENANTS OF THE COMPANY.

                  The Company further covenants and agrees with each Underwriter
as follows:

         (a) REGISTRATION STATEMENT MATTERS. The Company will (i) use its best
efforts to cause a registration statement on Form 8-A (the "Form 8-A
Registration Statement") as required by the Securities Exchange Act of 1934 (the
"Exchange Act") to become effective simultaneously with the Registration
Statement, (ii) use its best efforts to cause the Registration Statement to
become effective or, if the procedure in Rule 430A of the Securities Act is
followed, to prepare and timely file with the Commission under Rule 424(b) under
the Securities Act a Prospectus in a form approved by the Representative
containing information previously omitted at the time of effectiveness of the
Registration Statement in reliance on Rule 430A of the Securities Act and (iii)
not file any amendment to the Registration Statement or supplement to the
Prospectus of which the Representative shall not previously have been advised
and furnished with a copy or to which the Representative shall have reasonably
objected in writing or which is not in compliance with the Securities Act. If
the Company elects to rely on Rule 462(b) under the Securities Act, the Company
shall file a Rule 462(b) Registration Statement with the Commission in
compliance with Rule 462(b) under the Securities Act prior to the time
confirmations are sent or given, as specified by Rule 462(b)(2) under the
Securities Act, and shall pay the applicable fees in accordance with Rule 111
under the Securities Act.

         (b) SECURITIES ACT COMPLIANCE. The Company will advise the
Representative promptly (i) when the Registration Statement or any
post-effective amendment thereto shall have become effective, (ii) of receipt of
any comments from the Commission, (iii) of any request of the Commission for
amendment of the Registration Statement or for supplement to the Prospectus or
for any additional information and (iv) of the issuance by the Commission of any
stop order suspending the effectiveness of the Registration Statement or the use
of the Prospectus or of the institution of any proceedings for that purpose. The
Company will use its best efforts to prevent the issuance of any such stop order
preventing or suspending the use of the Prospectus and to obtain as soon as
possible the lifting thereof, if issued.

         (c) BLUE SKY COMPLIANCE. The Company will cooperate with the
Representatives and counsel for the Underwriters in endeavoring to qualify the
Shares for sale under the securities laws of such jurisdictions (both national
and foreign) as the Representative may reasonably have designated in writing and
will make such applications, file such documents, and furnish such information
as may be reasonably required for that purpose, provided the Company shall not
be required to qualify as a foreign corporation or to file a general consent to
service of process in any jurisdiction where it is not now so qualified or
required to file such a consent. The Company will, from time to time, prepare
and file such statements, reports and other documents, as are or may be required
to continue such qualifications in effect for so long a period as the
Representative may reasonably request for distribution of the Shares.

         (d) AMENDMENTS AND SUPPLEMENTS TO THE PROSPECTUS AND OTHER SECURITIES
ACT MATTERS. The Company will comply with the Securities Act and the Exchange
Act, and the rules


                                      -13-
<PAGE>

and regulations of the Commission thereunder, so as to permit the completion of
the distribution of the Shares as contemplated in this Agreement and the
Prospectus. If during the period in which a prospectus is required by law to be
delivered by an Underwriter or dealer, any event shall occur as a result of
which, in the judgment of the Company or in the reasonable opinion of the
Representative or counsel for the Underwriters, it becomes necessary to amend or
supplement the Prospectus in order to make the statements therein, in the light
of the circumstances existing at the time the Prospectus is delivered to a
purchaser, not misleading, or, if it is necessary at any time to amend or
supplement the Prospectus to comply with any law, the Company promptly will
prepare and file with the Commission, and furnish at its own expense to the
Underwriters and to dealers, an appropriate amendment to the Registration
Statement or supplement to the Prospectus so that the Prospectus as so amended
or supplemented will not, in the light of the circumstances when it is so
delivered, be misleading, or so that the Prospectus will comply with the law.

         (e) COPIES OF ANY AMENDMENTS AND SUPPLEMENTS TO THE PROSPECTUS. The
Company agrees to furnish the Representative, without charge, during the period
beginning on the date hereof and ending on the later of the First Closing Date
or such date, as in the opinion of counsel for the Underwriters, the Prospectus
is no longer required by law to be delivered in connection with sales by an
Underwriter or dealer (the "Prospectus Delivery Period"), as many copies of the
Prospectus and any amendments and supplements thereto as the Representative may
request.

         (f) INSURANCE. The Company shall (i) obtain Directors and Officers
liability insurance in the minimum amount of $10 million which shall apply to
the offering contemplated hereby and (ii) shall cause BancBoston Robertson
Stephens Inc. to be added as an additional insured to such policy in respect of
the offering contemplated hereby.

         (g) NOTICE OF SUBSEQUENT EVENTS. If at any time during the ninety (90)
day period after the Registration Statement becomes effective, any rumor,
publication or event relating to or affecting the Company shall occur as a
result of which in your opinion the market price of the Company Shares has been
or is likely to be materially affected (regardless of whether such rumor,
publication or event necessitates a supplement to or amendment of the
Prospectus), the Company will, after written notice from you advising the
Company to the effect set forth above, forthwith prepare, consult with you
concerning the substance of and disseminate a press release or other public
statement, reasonably satisfactory to you, responding to or commenting on such
rumor, publication or event.

         (h) USE OF PROCEEDS. The Company shall apply the net proceeds from the
sale of the Shares sold by it in the manner described under the caption "Use of
Proceeds" in the Prospectus.

         (i) TRANSFER AGENT. The Company shall engage and maintain, at its
expense, a registrar and transfer agent for the Company Shares.

         (j) EARNINGS STATEMENT. As soon as practicable, the Company will make
generally available to its security holders and to the Representative an
earnings statement (which need not be audited) covering the twelve-month period
ending December 31, 1999 that satisfies the


                                      -14-
<PAGE>

provisions of Section 11(a) of the Securities Act.

         (k) PERIODIC REPORTING OBLIGATIONS. During the Prospectus Delivery
Period the Company shall file, on a timely basis, with the Commission and the
Nasdaq National Market all reports and documents required to be filed under the
Exchange Act.

         (l) AGREEMENT NOT TO OFFER OR SELL ADDITIONAL SECURITIES. The Company
will not, without the prior written consent of BancBoston Robertson Stephens
Inc., for a period of 180 days following the date of the Prospectus, offer, sell
or contract to sell, or otherwise dispose of or enter into any transaction which
is designed to, or could be expected to, result in the disposition (whether by
actual disposition or effective economic disposition due to cash settlement or
otherwise by the Company or any affiliate of the Company or any person in
privity with the Company or any affiliate of the Company) directly or
indirectly, or announce the offering of, any other Common Shares or any
securities convertible into, or exchangeable for, Common Shares; provided,
however, that the Company may (i) issue and sell Common Shares pursuant to any
director or employee stock option plan, stock ownership plan or dividend
reinvestment plan of the Company in effect at the date of the Prospectus and
described in the Prospectus so long as none of those shares may be transferred
on during the period of 180 days from the date that the Registration Statement
is declared effective (the "Lock-Up Period") and the Company shall enter stop
transfer instructions with its transfer agent and registrar against the transfer
of any such Common Shares and (ii) the Company may issue Common Shares issuable
upon the conversion of securities or the exercise of warrants outstanding at the
date of the Prospectus and described in the Prospectus.

         (m) FUTURE REPORTS TO THE REPRESENTATIVE. During the period of five
years hereafter the Company will furnish to the Representative (i) as soon as
practicable after the end of each fiscal year, copies of the Annual Report of
the Company containing the balance sheet of the Company as of the close of such
fiscal year and statements of income, stockholders' equity and cash flows for
the year then ended and the opinion thereon of the Company's independent public
or certified public accountants; (ii) as soon as practicable after the filing
thereof, copies of each proxy statement, Annual Report on Form 10-K, Quarterly
Report on Form 10-Q, Current Report on Form 8-K or other report filed by the
Company with the Commission, the National Association of Securities Dealers, LLC
or any securities exchange; and (iii) as soon as available, copies of any report
or communication of the Company mailed generally to holders of its capital
stock.

         (n) EXCHANGE ACT COMPLIANCE. During the Prospectus Delivery Period, the
Company will file all documents required to be filed with the Commission
pursuant to Section 13, 14 or 15 of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), in the manner and within the time periods required
by the Exchange Act.

         SECTION 4. CONDITIONS OF THE OBLIGATIONS OF THE UNDERWRITERS. The
obligations of the several Underwriters to purchase and pay for the Shares as
provided herein on the First Closing Date and, with respect to the Option
Shares, the Second Closing Date, shall be subject to


                                      -15-
<PAGE>

the accuracy of the representations and warranties on the part of the Company
set forth in Section 1 hereof as of the date hereof and as of the First Closing
Date as though then made and, with respect to the Option Shares, as of the
Second Closing Date as though then made, to the timely performance by the
Company of its covenants and other obligations hereunder, and to each of the
following additional conditions:

         (a) COMPLIANCE WITH REGISTRATION REQUIREMENTS; NO STOP ORDER; NO
OBJECTION FROM THE NATIONAL ASSOCIATION OF SECURITIES DEALERS, LLC. The
Registration Statement shall have become effective prior to the execution of
this Agreement, or at such later date as shall be consented to in writing by
you; and no stop order suspending the effectiveness thereof shall have been
issued and no proceedings for that purpose shall have been initiated or, to the
knowledge of the Company or any Underwriter, threatened by the Commission, and
any request of the Commission for additional information (to be included in the
Registration Statement or the Prospectus or otherwise) shall have been complied
with to the satisfaction of Underwriters' Counsel; and the National Association
of Securities Dealers, LLC shall have raised no objection to the fairness and
reasonableness of the underwriting terms and arrangements.

         (b) CORPORATE PROCEEDINGS. All corporate proceedings and other legal
matters in connection with this Agreement, the form of Registration Statement
and the Prospectus, and the registration, authorization, issue, sale and
delivery of the Shares, shall have been reasonably satisfactory to Underwriters'
Counsel, and such counsel shall have been furnished with such papers and
information as they may reasonably have requested to enable them to pass upon
the matters referred to in this Section.

         (c) NO MATERIAL ADVERSE CHANGE. Subsequent to the execution and
delivery of this Agreement and prior to the First Closing Date, or the Second
Closing Date, as the case may be, there shall not have been any Material Adverse
Change in the condition (financial or otherwise), earnings, operations, business
or business prospects of the Company and its subsidiaries considered as one
enterprise from that set forth in the Registration Statement or Prospectus,
which, in your sole judgment, is material and adverse and that makes it, in your
sole judgment, impracticable or inadvisable to proceed with the public offering
of the Shares as contemplated by the Prospectus; and

         (d) OPINION OF COUNSEL FOR THE COMPANY. You shall have received on the
First Closing Date, or the Second Closing Date, as the case may be, an opinion
of Brobeck, Phleger & Harrison counsel for the Company substantially in the form
of EXHIBIT B attached hereto, dated the First Closing Date, or the Second
Closing Date, addressed to the Underwriters and with reproduced copies or signed
counterparts thereof for each of the Underwriters.

                  Counsel rendering the opinion contained in EXHIBIT B may rely
as to questions of law not involving the laws of the United States or the State
of New York and Delaware upon opinions of local counsel, and as to questions of
fact upon representations or certificates of officers of the Company, the
Selling Stockholders or officers of the Selling Stockholders (when the Selling
Stockholder is not a natural person), and of government officials, in which case
their opinion is to state that they are so relying and that they have no
knowledge of any material


                                      -16-
<PAGE>

misstatement or inaccuracy in any such opinion, representation or certificate.
Copies of any opinion, representation or certificate so relied upon shall be
delivered to you, as Representatives of the Underwriters, and to Underwriters'
Counsel.

         (e) OPINION OF PATENT COUNSEL FOR THE COMPANY. You shall have received
on the First Closing Date, or the Second Closing Date, as the case may be, an
opinion of ______________________, patent counsel for the Company substantially
in the form of Exhibit C attached hereto.

         (f) OPINION OF COUNSEL FOR THE UNDERWRITERS. You shall have received on
the First Closing Date or the Second Closing Date, as the case may be, an
opinion of Hale and Dorr LLP, substantially in the form of EXHIBIT D hereto. The
Company shall have furnished to such counsel such documents as they may have
requested for the purpose of enabling them to pass upon such matters.

         (g) ACCOUNTANTS' COMFORT LETTER. You shall have received on the First
Closing Date and on the Second Closing Date, as the case may be, a letter from
Arthur Andersen LLP addressed to the Underwriters, dated the First Closing Date
or the Second Closing Date, as the case may be, confirming that they are
independent certified public accountants with respect to the Company within the
meaning of the Act and the applicable published Rules and Regulations and based
upon the procedures described in such letter delivered to you concurrently with
the execution of this Agreement (herein called the "Original Letter"), but
carried out to a date not more than four (4) business days prior to the First
Closing Date or the Second Closing Date, as the case may be, (i) confirming, to
the extent true, that the statements and conclusions set forth in the Original
Letter are accurate as of the First Closing Date or the Second Closing Date, as
the case may be, and (ii) setting forth any revisions and additions to the
statements and conclusions set forth in the Original Letter which are necessary
to reflect any changes in the facts described in the Original Letter since the
date of such letter, or to reflect the availability of more recent financial
statements, data or information. The letter shall not disclose any change in the
condition (financial or otherwise), earnings, operations, business or business
prospects of the Company and its subsidiaries considered as one enterprise from
that set forth in the Registration Statement or Prospectus, which, in your sole
judgment, is material and adverse and that makes it, in your sole judgment,
impracticable or inadvisable to proceed with the public offering of the Shares
as contemplated by the Prospectus. The Original Letter from Arthur Andersen LLP
shall be addressed to or for the use of the Underwriters in form and substance
satisfactory to the Underwriters and shall (i) represent, to the extent true,
that they are independent certified public accountants with respect to the
Company within the meaning of the Act and the applicable published Rules and
Regulations, (ii) set forth their opinion with respect to their examination of
the consolidated balance sheet of the Company as of December 31, 1998 and
related consolidated statements of operations, shareholders' equity, and cash
flows for the twelve (12) months ended December 31, 1998, (iii) state that
Arthur Andersen LLP has performed the procedures set out in Statement on
Auditing Standards No. 71 ("SAS 71") for a review of interim financial
information and providing the report of Arthur Andersen LLP as described in SAS
71 on the financial statements for each of the quarters in the second-quarter
period ended June 30, 1999


                                      -17-
<PAGE>

(the "Quarterly Financial Statements"), (iv) state that in the course of such
review, nothing came to their attention that leads them to believe that any
material modifications need to be made to any of the Quarterly Financial
Statements in order for them to be in compliance with generally accepted
accounting principles consistently applied across the periods presented, and
address other matters agreed upon by Arthur Andersen LLP and you. In addition,
you shall have received from Arthur Andersen LLP a letter addressed to the
Company and made available to you for the use of the Underwriters stating that
their review of the Company's system of internal accounting controls, to the
extent they deemed necessary in establishing the scope of their examination of
the Company's consolidated financial statements as of December 31, 1998, did not
disclose any weaknesses in internal controls that they considered to be material
weaknesses.

         (h) OFFICERS' CERTIFICATE. You shall have received on the First Closing
Date and the Second Closing Date, as the case may be, a certificate of the
Company, dated the First Closing Date or the Second Closing Date, as the case
may be, signed by the Chief Executive Officer and Chief Financial Officer of the
Company, to the effect that, and you shall be satisfied that:

         (i) The representations and warranties of the Company in this Agreement
         are true and correct, as if made on and as of the First Closing Date or
         the Second Closing Date, as the case may be, and the Company has
         complied with all the agreements and satisfied all the conditions on
         its part to be performed or satisfied at or prior to the First Closing
         Date or the Second Closing Date, as the case may be;

         (ii) No stop order suspending the effectiveness of the Registration
         Statement has been issued and no proceedings for that purpose have been
         instituted or are pending or threatened under the Act;

         (iii) When the Registration Statement became effective and at all times
         subsequent thereto up to the delivery of such certificate, the
         Registration Statement and the Prospectus, and any amendments or
         supplements thereto, contained all material information required to be
         included therein by the Securities Act and in all material respects
         conformed to the requirements of the Securities Act, the Registration
         Statement and the Prospectus, and any amendments or supplements
         thereto, did not and does not include any untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein not misleading;
         and, since the effective date of the Registration Statement, there has
         occurred no event required to be set forth in an amended or
         supplemented Prospectus which has not been so set forth; and

         (iv) Subsequent to the respective dates as of which information is
         given in the Registration Statement and Prospectus, there has not been
         (a) any material adverse change in the condition (financial or
         otherwise), earnings, operations, business or business prospects of the
         Company and its subsidiaries considered as one enterprise, (b) any
         transaction that is material to the Company and its subsidiaries
         considered as one enterprise, except transactions entered into in the
         ordinary course of business, (c) any


                                      -18-
<PAGE>

         obligation, direct or contingent, that is material to the Company and
         its subsidiaries considered as one enterprise, incurred by the Company
         or its subsidiaries, except obligations incurred in the ordinary course
         of business, (d) any change in the capital stock or outstanding
         indebtedness of the Company or any of its subsidiaries that is material
         to the Company and its subsidiaries considered as one enterprise, (e)
         any dividend or distribution of any kind declared, paid or made on the
         capital stock of the Company or any of its subsidiaries, or (f) any
         loss or damage (whether or not insured) to the property of the Company
         or any of its subsidiaries which has been sustained or will have been
         sustained which has a material adverse effect on the condition
         (financial or otherwise), earnings, operations, business or business
         prospects of the Company and its subsidiaries considered as one
         enterprise.

         (i) LOCK-UP AGREEMENT FROM CERTAIN STOCKHOLDERS OF THE COMPANY. The
Company shall have obtained and delivered to you an agreement substantially in
the form of EXHIBIT A attached hereto from each officer and director of the
Company, and each beneficial owner of one or more percent of the outstanding
issued share capital of the Company.

to the furnishing of Prospectuses.

         (l) ADDITIONAL DOCUMENTS. On or before each of the First Closing Date
and the Second Closing Date, as the case may be, the Representative and counsel
for the Underwriters shall have received such information, documents and
opinions as they may reasonably require for the purposes of enabling them to
pass upon the issuance and sale of the Shares as contemplated herein, or in
order to evidence the accuracy of any of the representations and warranties, or
the satisfaction of any of the conditions or agreements, herein contained.

                  If any condition specified in this Section 4 is not satisfied
when and as required to be satisfied, this Agreement may be terminated by the
Representative by notice to the Company at any time on or prior to the First
Closing Date and, with respect to the Option Shares, at any time prior to the
Second Closing Date, which termination shall be without liability on the part of
any party to any other party, except that Section 5 (Payment of Expenses),
Section 6 (Reimbursement of Underwriters' Expenses), Section 7 (Indemnification
and Contribution) and Section 10 (Representations and Indemnities to Survive
Delivery) shall at all times be effective and shall survive such termination.

is terminated by the Representative pursuant to Section 4, Section 7, Section 8
or Section 9, or if the sale to the Underwriters of the Shares on the First
Closing Date is not consummated because of any refusal, inability or failure on
the part of the Company to perform any agreement herein or to comply with any
provision hereof, the Company agrees to reimburse the Representative and the
other Underwriters (or such Underwriters as have terminated this Agreement with
respect to themselves), severally, upon demand for all out-of-pocket expenses
that shall have been reasonably incurred by the Representative and the
Underwriters in connection with the proposed purchase and the offering and sale
of the Shares, including but not limited to fees and disbursements of counsel,
printing expenses, travel expenses, postage, facsimile and telephone charges.

         SECTION 7. INDEMNIFICATION AND CONTRIBUTION.

         (a)      Indemnification of the Underwriters.

                  (1) The Company agrees to indemnify and hold harmless each
Underwriter, its officers and employees, and each person, if any, who controls
any Underwriter within the meaning of the Securities Act and the Exchange Act
against any loss, claim, damage, liability or expense, as incurred, to which
such Underwriter or such controlling person may become subject,


                                      -20-
<PAGE>

under the Securities Act, the Exchange Act or other federal or state statutory
law or regulation, or at common law or otherwise (including in settlement of any
litigation, if such settlement is effected with the written consent of the
Company, which consent shall not be unreasonably withheld), insofar as such
loss, claim, damage, liability or expense (or actions in respect thereof as
contemplated below) arises out of or is based (i) upon any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement, or any amendment thereto, including any information deemed to be a
part thereof pursuant to Rule 430A or Rule 434 under the Securities Act, or the
omission or alleged omission therefrom of a material fact required to be stated
therein or necessary to make the statements therein not misleading; or (ii) upon
any untrue statement or alleged untrue statement of a material fact contained in
any preliminary prospectus or the Prospectus (or any amendment or supplement
thereto), or the omission or alleged omission therefrom of a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading; or (iii) in whole or
in part upon any inaccuracy in the representations and warranties of the Company
contained herein; or (iv) in whole or in part upon any failure of the Company to
perform its obligations hereunder or under law; or (v) any act or failure to act
or any alleged act or failure to act by any Underwriter in connection with, or
relating in any manner to, the Shares or the offering contemplated hereby, and
which is included as part of or referred to in any loss, claim, damage,
liability or action arising out of or based upon any matter covered by clause
(i), (ii), (iii) or (iv) above, provided that the Company shall not be liable
under this clause (v) to the extent that a court of competent jurisdiction shall
have determined by a final judgment that such loss, claim, damage, liability or
action resulted directly from any such acts or failures to act undertaken or
omitted to be taken by such Underwriter through its bad faith or willful
misconduct; and to reimburse each Underwriter and each such controlling person
for any and all expenses (including the fees and disbursements of counsel chosen
by BancBoston Robertson Stephens Inc.) as such expenses are reasonably incurred
by such Underwriter or such controlling person in connection with investigating,
defending, settling, compromising or paying any such loss, claim, damage,
liability, expense or action; provided, however, that the foregoing indemnity
agreement shall not apply to any loss, claim, damage, liability or expense to
the extent, but only to the extent, arising out of or based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in
reliance upon and in conformity with written information furnished to the
Company by the Representative expressly for use in the Registration Statement,
any preliminary prospectus or the Prospectus (or any amendment or supplement
thereto); and provided, further, that with respect to any preliminary
prospectus, the foregoing indemnity agreement shall not inure to the benefit of
any Underwriter from whom the person asserting any loss, claim, damage,
liability or expense purchased Shares, or any person controlling such
Underwriter, if copies of the Prospectus were timely delivered to the
Underwriter pursuant to Section 2 and a copy of the Prospectus (as then amended
or supplemented if the Company shall have furnished any amendments or
supplements thereto) was not sent or given by or on behalf of such Underwriter
to such person, if required by law so to have been delivered, at or prior to the
written confirmation of the sale of the Shares to such person, and if the
Prospectus (as so amended or supplemented) would have cured the defect giving
rise to such loss, claim, damage, liability or expense. The indemnity agreement
set forth in this Section 7(a) shall be in addition to any liabilities that the
Company may otherwise have.

         (b) INDEMNIFICATION OF THE COMPANY, ITS DIRECTORS AND OFFICERS. Each
Underwriter agrees, severally and not jointly, to indemnify and hold harmless
the Company, each of its directors, each of its officers who signed the
Registration Statement and each person, if any, who controls the Company within
the meaning of the Securities Act or the Exchange Act, against any loss, claim,
damage, liability or expense, as incurred, to which the Company, or any such
director, officer or controlling person may become subject, under the Securities
Act, the Exchange Act, or other federal or state statutory law or regulation, or
at common law or otherwise (including in settlement of any litigation, if such
settlement is effected with the written consent of such Underwriter), insofar as
such loss, claim, damage, liability or expense (or actions in respect thereof as
contemplated below) arises out of or is based upon any untrue or alleged untrue
statement of a material fact contained in the Registration Statement, any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto), or arises out of or is based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in the Registration Statement, any preliminary
prospectus, the Prospectus (or any amendment or supplement thereto), in reliance
upon and in conformity with written information furnished to the Company by the
Representative expressly for use therein; and to reimburse the Company, or any
such director, officer or controlling person for any legal and other expense
reasonably incurred by the Company, or any such director, officer or controlling
person in connection with investigating, defending, settling, compromising or
paying any such loss, claim, damage, liability, expense or action. The indemnity
agreement set forth in this Section 7(b) shall be in addition to any liabilities
that each Underwriter may otherwise have.

         (c) INFORMATION PROVIDED BY THE UNDERWRITERS. The Company hereby
acknowledges that the only information that the Underwriters have furnished to
the Company expressly for use in the Registration Statement, any preliminary
prospectus or the Prospectus (or any amendment or supplement thereto) are the
statements set forth in the table in the first paragraph and the second
paragraph under the caption "Underwriting" in the Prospectus; and the
Underwriters confirm that such statements are correct.

         (d) NOTIFICATIONS AND OTHER INDEMNIFICATION PROCEDURES. Promptly after
receipt by an indemnified party under this Section 7 of notice of the
commencement of any action, such indemnified party will, if a claim in respect
thereof is to be made against an indemnifying party under this Section 7, notify
the indemnifying party in writing of the commencement thereof, but the omission
so to notify the indemnifying party will not relieve it from any liability which
it may have to any indemnified party for contribution or otherwise than under
the indemnity agreement contained in this Section 7 or to the extent it is not
prejudiced as a proximate result of such failure. In case any such action is
brought against any indemnified party and such indemnified party seeks or
intends to seek indemnity from an indemnifying party, the indemnifying party
will be entitled to participate in, and, to the extent that it shall elect,
jointly with all other indemnifying parties similarly notified, by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof with counsel
reasonably satisfactory to such indemnified party;


                                      -22-
<PAGE>

provided, however, if the defendants in any such action include both the
indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that a conflict may arise between the positions of the
indemnifying party and the indemnified party in conducting the defense of any
such action or that there may be legal defenses available to it and/or other
indemnified parties which are different from or additional to those available to
the indemnifying party, the indemnified party or parties shall have the right to
select separate counsel to assume such legal defenses and to otherwise
participate in the defense of such action on behalf of such indemnified party or
parties. Upon receipt of notice from the indemnifying party to such indemnified
party of such indemnifying party's election so to assume the defense of such
action and approval by the indemnified party of counsel, the indemnifying party
will not be liable to such indemnified party under this Section 7 for any legal
or other expenses subsequently incurred by such indemnified party in connection
with the defense thereof unless (i) the indemnified party shall have employed
separate counsel in accordance with the proviso to the next preceding sentence
(it being understood, however, that the indemnifying party shall not be liable
for the expenses of more than one separate counsel (together with local
counsel), approved by the indemnifying party (BancBoston Robertson Stephens Inc.
in the case of Section 7(b) and Section 8), representing the indemnified parties
who are parties to such action), (ii) the indemnifying party shall not have
employed counsel satisfactory to the indemnified party to represent the
indemnified party within a reasonable time after notice of commencement of the
action, or (iii) the indemnifying party has authorized the employment of counsel
for the indemnified party at the expense of the indemnifying party, in each of
which cases the fees and expenses of counsel shall be at the expense of the
indemnifying party.

         (e) SETTLEMENTS. The indemnifying party under this Section 7 shall not
be liable for any settlement of any proceeding effected without its written
consent, which consent shall not be unreasonably withheld, but if settled with
such consent or if there be a final judgment for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party against any loss, claim, damage,
liability or expense by reason of such settlement or judgment. Notwithstanding
the foregoing sentence, if at any time an indemnified party shall have requested
an indemnifying party to reimburse the indemnified party for fees and expenses
of counsel as contemplated by Section 7(d) hereof, the indemnifying party agrees
that it shall be liable for any settlement of any proceeding effected without
its written consent if (i) such settlement is entered into more than 30 days
after receipt by such indemnifying party of the aforesaid request and (ii) such
indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such settlement. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement, compromise or consent to the entry of judgment in any pending or
threatened action, suit or proceeding in respect of which any indemnified party
is or could have been a party and indemnity was or could have been sought
hereunder by such indemnified party, unless such settlement, compromise or
consent includes (i) an unconditional release of such indemnified party from all
liability on claims that are the subject matter of such action, suit or
proceeding and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act by or on behalf of any indemnified party.

         (f) CONTRIBUTION. If the indemnification provided for in this Section 7
is unavailable


                                      -23-
<PAGE>

to or insufficient to hold harmless an indemnified party under Section 7(a) or
(b) above in respect of any losses, claims, damages or liabilities (or actions
or proceedings in respect thereof) then each indemnifying party shall contribute
to the aggregate amount paid or payable by such indemnified party in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and the Underwriters on the other from the offering of
the Shares. If, however, the allocation provided by the immediately preceding
sentence is not permitted by applicable law then each indemnifying party shall
contribute to such amount paid or payable by such indemnified party in such
proportion as is appropriate to reflect not only such relative benefits but also
the relative fault of the Company on the one hand and the Underwriters on the
other in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities, (or actions or proceedings in respect
thereof), as well as any other relevant equitable considerations. The relative
benefits received by the Company on the one hand and the Underwriter on the
other shall be deemed to be in the same proportion as the total net proceeds
from the offering (before deducting expenses) received by the Company bears to
the total underwriting discounts and commissions received by the Underwriters,
in each case as set forth in the table on the cover page of the Prospectus. The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company on the one hand or the Underwriters on the other and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

         The Company and Underwriters agree that it would not be just and
equitable if contributions pursuant to this Section 7(f) were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to above in this Section 7(f). The amount paid
or payable by an indemnified party as a result of the losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) referred to above in
this Section 7(f) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
subsection (f), (i) no Underwriter shall be required to contribute any amount in
excess of the underwriting discounts and commissions applicable to the Shares
purchased by such Underwriter and (ii) no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations in this Section 7(f)
to contribute are several in proportion to their respective underwriting
obligations and not joint.

         (g) TIMING OF ANY PAYMENTS OF INDEMNIFICATION. Any losses, claims,
damages, liabilities or expenses for which an indemnified party is entitled to
indemnification or contribution under this Section 7 shall be paid by the
indemnifying party to the indemnified party as such losses, claims, damages,
liabilities or expenses are incurred, but in all cases, no later than thirty
(30) days of invoice to the indemnifying party.


                                      -24-

         (h) SURVIVAL. The indemnity and contribution agreements contained in
this Section 7 and the representation and warranties of the Company set forth in
this Agreement shall remain operative and in full force and effect, regardless
of (i) any investigation made by or on behalf of any Underwriter or any person
controlling any Underwriter, the Company, its directors or officers or any
persons controlling the Company, (ii) acceptance of any Shares and payment
therefor hereunder, and (iii) any termination of this Agreement. A successor to
any Underwriter, or to the Company, its directors or officers, or any person
controlling the Company, shall be entitled to the benefits of the indemnity,
contribution and reimbursement agreements contained in this Section 7.

         (i) ACKNOWLEDGEMENTS OF PARTIES. The parties to this Agreement hereby
acknowledge that they are sophisticated business persons who were represented by
counsel during the negotiations regarding the provisions hereof including,
without limitation, the provisions of this Section 7, and are fully informed
regarding said provisions. They further acknowledge that the provisions of this
Section 7 fairly allocate the risks in light of the ability of the parties to
investigate the Company and its business in order to assure that adequate
disclosure is made in the Registration Statement and Prospectus as required by
the Securities Act and the Exchange Act.

         SECTION 8. DEFAULT OF ONE OR MORE OF THE SEVERAL UNDERWRITERS. If, on
the First Closing Date or the Second Closing Date, as the case may be, any one
or more of the several Underwriters shall fail or refuse to purchase Shares that
it or they have agreed to purchase hereunder on such date, and the aggregate
number of Common Shares which such defaulting Underwriter or Underwriters agreed
but failed or refused to purchase does not exceed 10% of the aggregate number of
the Shares to be purchased on such date, the other Underwriters shall be
obligated, severally, in the proportions that the number of Firm Common Shares
set forth opposite their respective names on SCHEDULE A bears to the aggregate
number of Firm Shares set forth opposite the names of all such non-defaulting
Underwriters, or in such other proportions as may be specified by the
Representative with the consent of the non-defaulting Underwriters, to purchase
the Shares which such defaulting Underwriter or Underwriters agreed but failed
or refused to purchase on such date. If, on the First Closing Date or the Second
Closing Date, as the case may be, any one or more of the Underwriters shall fail
or refuse to purchase Shares and the aggregate number of Shares with respect to
which such default occurs exceeds 10% of the aggregate number of Shares to be
purchased on such date, and arrangements satisfactory to the Representative and
the Company for the purchase of such Shares are not made within 48 hours after
such default, this Agreement shall terminate without liability of any party to
any other party except that the provisions of Section 4, and Section 7 shall at
all times be effective and shall survive such termination. In any such case
either the Representative or the Company shall have the right to postpone the
First Closing Date or the Second Closing Date, as the case may be, but in no
event for longer than seven days in order that the required changes, if any, to
the Registration Statement and the Prospectus or any other documents or
arrangements may be effected.

                  As used in this Agreement, the term "Underwriter" shall be
deemed to include any


                                      -25-
<PAGE>

person substituted for a defaulting Underwriter under this Section 8. Any action
taken under this Section 8 shall not relieve any defaulting Underwriter from
liability in respect of any default of such Underwriter under this Agreement.

         SECTION 9. TERMINATION OF THIS AGREEMENT. Prior to the First Closing
Date, this Agreement may be terminated by the Representative by notice given to
the Company if at any time (i) trading or quotation in any of the Company's
securities shall have been suspended or limited by the Commission or by the
Nasdaq Stock Market, or trading in securities generally on either the Nasdaq
Stock Market or the New York Stock Exchange shall have been suspended or
limited, or minimum or maximum prices shall have been generally established on
any of such stock exchanges by the Commission or the National Association of
Securities Dealers, LLC; (ii) a general banking moratorium shall have been
declared by any of federal, New York, Delaware or California authorities; (iii)
there shall have occurred any outbreak or escalation of national or
international hostilities or any crisis or calamity, or any change in the United
States or international financial markets, or any substantial change or
development involving a prospective change in United States' or international
political, financial or economic conditions, as in the judgment of the
Representative is material and adverse and makes it impracticable or inadvisable
to market the Common Shares in the manner and on the terms described in the
Prospectus or to enforce contracts for the sale of securities; (iv) in the
judgment of the Representative there shall have occurred any Material Adverse
Change; or (v) the Company shall have sustained a loss by strike, fire, flood,
earthquake, accident or other calamity of such character as in the judgment of
the Representative may interfere materially with the conduct of the business and
operations of the Company regardless of whether or not such loss shall have been
insured. Any termination pursuant to this Section 9 shall be without liability
on the part of (a) the Company to any Underwriter, except that the Company shall
be obligated to reimburse the expenses of the Representative and the
Underwriters pursuant to Sections 5 and 6 hereof, (b) any Underwriter to the
Company, or (c) of any party hereto to any other party except that the
provisions of Section 7 shall at all times be effective and shall survive such
termination.

         SECTION 10. REPRESENTATIONS AND INDEMNITIES TO SURVIVE DELIVERY. The
respective indemnities, agreements, representations, warranties and other
statements of the Company, of its officers and of the several Underwriters set
forth in or made pursuant to this Agreement will remain in full force and
effect, regardless of any investigation made by or on behalf of any Underwriter
or the Company or any of its or their partners, officers or directors or any
controlling person, as the case may be, and will survive delivery of and payment
for the Shares sold hereunder and any termination of this Agreement.

         SECTION 11. NOTICES. All communications hereunder shall be in writing

         SECTION 14. GOVERNING LAW PROVISIONS.

         (a) GOVERNING LAW. This agreement shall be governed by and construed in
accordance with the internal laws of the State of New York applicable to
agreements made and to be performed in such state.

         (b) CONSENT TO JURISDICTION. Any legal suit, action or proceeding
arising out of or based upon this Agreement or the transactions contemplated
hereby ("Related Proceedings" may be instituted in the federal courts of the
United States of America located in the City and County of San Francisco or the
courts of the State of California in each case located in the City and County of
San Francisco (collectively, the "Specified Courts"), and each party irrevocably
submits to the exclusive jurisdiction (except for proceedings instituted in
regard to the enforcement of a judgment of any such court (a "Related
Judgment"), as to which such jurisdiction is non-exclusive) of such courts in
any such suit, action or proceeding. Service of any process, summons, notice or
document by mail to such party's address set forth above shall be effective
service of process for any suit, action or other proceeding brought in any such
court. The parties irrevocably and unconditionally waive any objection to the
laying of venue of any suit, action or other proceeding in the Specified Courts
and irrevocably and unconditionally waive and agree not to plead or claim in any
such court that any such suit, action or other proceeding brought in any such
court has been brought in an inconvenient forum. Each party not located in the
United States irrevocably appoints CT Corporation System, which currently
maintains a San Francisco office at 49 Stevenson Street, San Francisco,
California 94105, United States of America, as its agent to receive service of
process or other legal summons for purposes of any such suit, action or
proceeding that may be instituted in any state or federal court in the City and
County of San Francisco.

         (c) WAIVER OF IMMUNITY. With respect to any Related Proceeding, each
party irrevocably waives, to the fullest extent permitted by applicable law, all
immunity (whether on the basis of sovereignty or otherwise) from jurisdiction,
service of process, attachment (both before and after judgment) and execution to
which it might otherwise be entitled in the Specified Courts, and with respect
to any Related Judgment, each party waives any such immunity in the Specified
Courts or any other court of competent jurisdiction, and will not raise or claim
or cause to be pleaded any such immunity at or in respect of any such Related
Proceeding or Related Judgment, including, without limitation, any immunity
pursuant to the United States Foreign Sovereign Immunities Act of 1976, as
amended.

         SECTION 15. GENERAL PROVISIONS. This Agreement constitutes the entire
agreement of the parties to this Agreement and supersedes all prior written or
oral and all contemporaneous oral agreements, understandings and negotiations
with respect to the subject matter hereof. This Agreement may be executed in two
or more counterparts, each one of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
This Agreement may not be amended or modified unless in writing by all of the
parties hereto, and no condition herein (express or implied) may be waived
unless waived in writing by each party

           Re:  Predictive Systems, Inc.--Registration Statement on

                Form S-1 (File No. 333-84045)

Ladies and Gentlemen:

    We have acted as counsel to Predictive Systems, Inc., a Delaware corporation
(the "Company"), in connection with the proposed issuance and sale by the
Company of up to 4,600,000 shares of the Company's Common Stock (the "Shares")
pursuant to the Company's Registration Statement on Form S-1 (the "Registration
Statement") filed with the Securities and Exchange Commission under the
Securities Act of 1933, as amended (the "Act").

    This opinion is being furnished in accordance with the requirements of Item
16(a) of Form S-1.

    We have reviewed the Company's charter documents and the corporate
proceedings taken by the Company in connection with the issuance and sale of the
Shares. Based on such review, we are of the opinion that the Shares have been
duly authorized, and if, as and when issued in accordance with the Registration
Statement and the related prospectus (as amended and supplemented through the
date of issuance) will be legally issued, fully paid and nonassessable.

    We consent to the filing of this opinion letter as Exhibit 5.1 to the
Registration Statement and to the reference to this firm under the caption
"Legal Matters" in the prospectus which is part of the Registration Statement.
In giving this consent, we do not thereby admit that we are within the category
of persons whose consent is required under Section 7 of the Act or the rules and
regulations of the Securities and Exchange Commission promulgated thereunder.

    This opinion letter is rendered as of the date first written above and we
disclaim any obligation to advise you of facts, circumstances, events or
developments which may be brought to our attention through the time of
effectiveness of the Registration Statement, and which may alter, affect or
modify the opinion expressed herein. Our opinion is expressly limited to the
matters set forth above and we render no opinion, whether by implication or
otherwise, as to any other matters relating to the Company or the Shares.

                                          Very truly your,

                                          /s/ Brobeck, Phleger & Harrison LLP

This Development and License Agreement (the "Agreement"), dated this 29th day of
July, 1998, is by and between Bear, Stearns & Co. Inc, a Delaware corporation,
having its principal offices at 245 Park Avenue, New York, NY 10167 and other
direct and indirect subsidiaries at the relevant time of its ultimate corporate
parent (collectively, "Bear Stearns"), and Predictive Systems, Inc, having
offices at 145 Hudson Street, New York, NY 10013 ("Predictive").

                                    RECITALS

         WHEREAS, Predictive wishes from time to time to perform Enterprise
Management services for Bear Stearns and Bear Stearns wishes to consider
engaging Predictive to perform such services (an "Assignment").

         WHEREAS, in the interest of streamlining the startup phase of any such
Assignment, Bear Stearns and Predictive wish to agree in advance as to certain
terms and conditions under which such services may be rendered;

         THEREFORE, for good and valuable consideration given pursuant to the
terms, conditions and covenants contained herein, Bear Stearns and Predictive
hereby agree as follows:

SECTION 1:        STATEMENT OF WORK, SERVICES AND DELIVERABLES

1.1.     Each Assignment will be commenced by a Statement of Work executed by
         both Bear Stearns and Predictive (a "Statement of Work") referencing
         this Agreement, and setting forth: (i) the deliverables to be produced
         (the "Deliverables") and/or the other services to be performed (the
         "Services"); (ii) the schedule for delivery of such Deliverables,
         performance of such Services, and the date of completion of
         Predictive's performance under the Statement of Work ("Completion
         Date"); (iii) the agreed fees and costs consistent with this Agreement
         for such Services and Deliverables ("Statement of Work Fees"); (iv) the
         schedule for payment of such fees and costs ("Payment Schedule"); and
         (v) the acceptance criteria against which the completeness of
         deliverables will be measured ("Acceptance Criteria"). Notwithstanding
         the foregoing, whether or not such Statement of Work sets forth the
         items set forth in (i) through (v) above or refers to this Agreement,
         the terms, conditions and provisions of this Agreement shall apply to
         such Assignment and shall be automatically incorporated into such
         Statement of Work, regardless of the terms discussed with any third
         party.

1.2.     As and when required by and Statement of Work and this Agreement,
         Predictive shall perform for Bear Stearns the Services described in the
         Statement of Work and shall deliver to Bear Stearns the Deliverables
         described in the Statement of Work.

1.3.     Notwithstanding the generality of Section 1.2., above and in addition
         thereto, at the conclusion of each month during the term of each
         Statement of Work, Predictive shall deliver to Bear Stearns all
         Deliverables (including drafts and other work in progress) produced by
         Predictive in the performance of the Statement of Work over the course
         of that month.

1.4.     Predictive warrants that it has or will provide the resources and
         personnel necessary to carry out its work under each Statement of Work
         and will use its best efforts to perform all work required under this
         Agreement and each Statement of Work in a timely, skillful, and
         efficient manner. Predictive shall not be responsible for any delay in
         the performance of Services due to causes beyond reasonable control of
         Predictive.

1.5.     After completion of each milestone of the Statement of Work against
         which a payment in the Payment Schedule is tied, (other than
         obligations intended to survive acceptance by Bear Stearns), Predictive
         will notify Bear Stearns in writing that Predictive has completed its
         performance, that the Services are fully implemented, that the
         Deliverables are fully implemented, and that Predictive's testing is
         completed. Bear Stearns, with the cooperation and assistance of
         Predictive, shall then be entitled to conduct a
<PAGE>

         comprehensive, integrated acceptance test of the Acceptance Criteria on
         all the Services and Deliverables ("Acceptance Test"), and, if Bear
         Stearns reasonably determines that any material part of the Acceptance
         Criteria are not met during the Acceptance Test, to reject such
         Services and/or Deliverables by notifying Predictive in writing.
         "Acceptance" shall mean the receipt by Predictive of written
         notification from Bear Stearns that the Acceptance Test on the Services
         and Deliverables has been successfully completed. Any rejection shall
         state specifically the manner in which the Services and Deliverables
         are defective. In the event of rejection, Predictive shall correct any
         deficiencies and shall resubmit such Services and Deliverables for
         further Acceptance Testing in accordance with this paragraph. Bear
         Stearns shall not be invoiced for more than 80% of the aggregate amount
         due for any Services or Deliverables until such Services and
         Deliverables satisfy the Acceptance Test and are accepted by Bear
         Stearns pursuant to this Section 1.5.

SECTION 2:        PROPRIETARY RIGHTS IN DELIVERABLES, ETC.

2.1      Predictive agrees that (i) any and all Deliverables, (ii) any and all
         original other works of authorship, including, but not limited to all,
         user documentation, papers, documents, drawings, databases and other
         compilations which may be created, compiled or produced by Predictive
         or any of its subcontractors, consultants or employees in the course of
         performing Services or producing Deliverables for Bear Stearns (along
         with the items described in (i) above, collectively, "Works of
         Authorship"), and (iii) any and all copyrights and other proprietary
         rights and all foreign and domestic, registered and unregistered,
         copyrights, applications for registrations therefor and other
         proprietary rights related to any Works of Authorship (collectively,
         "Copyrights"), shall be deemed to be works made for hire for and the
         exclusive property of Bear Stearns. Except to the extent specifically
         agreed in the Statement of Work, to the extent that Predictive has or
         obtains any right, title or interest in or to any Work of Authorship of
         Copyright, Predictive hereby assigns and agrees to assign to Bear
         Stearns all of such right, title and interest therein and thereto, and
         to the extent that any employee, agent or sub-contractor of Predictive
         has or obtains any right, title or interest in or to any Work of
         Authorship or Copyright, Predictive shall cause such employee, agent or
         sub-contractor to assign to Bear Stearns all of such right, title and
         interest therein and thereto.

2.2.     To the extent that any Deliverables or Services embody, contain or
         disclose any ideas, concepts, know-how, inventions, formulas,
         techniques, processes, ideas, algorithms, discoveries, designs,
         developments, improvements, techniques or expertise that are known by
         Predictive prior to Predictive's work for Bear Stearns or is developed
         by Predictive during the course of Predictive's work for Bear Stearns
         (collectively "Know-How") of Predictive, Predictive shall retain
         ownership of such Know-How, provided that Bear Stearns shall have the
         full, unrestricted and non-exclusive right to use, disclose, prepare
         works of authorship based upon any Know-How embodied by, contained in
         or disclosed by the Deliverables of Services and to copy, display and
         distribute any such works of authorship.

2.3.     Nothing herein shall prevent Predictive from providing services
         substantially similar to those contemplated herein, whether for a
         competitor of Bear Stearns or otherwise, and the parties expressly
         agree that in providing such services, or in developing its general,
         commercially available software products, Predictive may directly or
         indirectly utilize residual know-how in its area of expertise not
         specific to Bear Stearns resulting from the performance of the services
         contemplated herein.

2.4.     Upon the request of Bear Stearns, Predictive shall at Bear Stearns'
         reasonable out-of-pocket cost and expense do all acts and things,
         including, but not limited to, making and executing documents,
         applications, deeds, license agreements, assignments, transfers,
         conveyances, powers of attorney and instruments, using its best efforts
         to obtain the cooperation of and bringing claims and actions against
         its employees, ex-employees, agents, ex-agents and independent
         contractors and giving information and testimony, in each case,
         requested at any time and from time to time by Bear Stearns, in its
         good faith discretion, to vest, secure, defend, protect and/or evidence
         the right, title and ownership of Bear Stearns in and to any and all
         Works of Authorship and Copyrights. Predictive hereby appoints Bear
         Stearns and is successors and assigns as Predictive's attorney-in-fact,
         with full power of substitution, in the name and stead of Predictive or
         Bear Stearns, for the benefit of Bear Stearns and its successors and
         assigns, to from time to time do any and all such acts and things which
         Predictive is obligated to do under his paragraph. Predictive declares
         that the appointment made and the powers granted hereby are coupled
         with an interest and are irrevocable.

         used, examined or copied by any third party without the written
         direction or consent of Bear Stearns. Predictive shall, and shall cause
         its employees and agents to, place an appropriate emblem or other
         annotation on any and all Bear Stearns Documentation that is in the
         possession of Predictive or any of its employees or agents evidencing
         Bear Stearns' ownership of such Bear Stearns Documentation. Predictive
         acknowledges that the use or disclosure of any Bear Stearns Information
         in a manner inconsistent with this Agreement may cause Bear Stearns
         irreparable damage, and that Bear Stearns shall have the right to seek
         injunctive relief to prevent such unauthorized use or disclosure, and
         to such damages as are occasioned by such unauthorized use or
         disclosure.

8.2      Notwithstanding anything set forth in this Agreement, the
         confidentiality provisions of this Agreement, including, but not
         limited to the above shall not apply to: (a) information which (i) is
         already in the possession of the party subject to the confidentiality
         obligations, ii) is or become generally available to the public other
         than as a result of improper disclosure by the party subject to the
         confidentiality obligations or its agents, representatives or employees
         iii) is independently developed by the party subject to the
         confidentiality obligations, or (iv) become available to the party
         subject to the confidentiality obligations on a non-confidential basis
         from a source which, to the best of such party's knowledge, is not
         prohibited from disclosing such information to the party subject to the
         confidentiality obligations by a legal, contractual or fiduciary
         obligation to the party subject to the confidentiality obligations, or
         (b) disclosures required by applicable law, rule, regulation or order
         or to legal counsel or auditors of the party who are subject to an
         obligation of confidentiality.

SECTION 9:        INFRINGEMENT INDEMNIFICATION

9.1      Predictive shall indemnify, defend and hold harmless Bear Stearns for,
         from and against any and all losses, liabilities, damages, demands,
         claims (including without limitation taxes), and costs, payments and
         expenses (including without limitation any and all reasonable
         attorneys' fees, reasonable costs of investigation, litigation and
         settlement, interest and any judgments and penalties) (collectively,
         "Losses") as incurred, arising out of, or in connection with any claims
         made against Bear Stearns in connection with any allegations that any
         of the Deliverables or their use, sale, disclosure, execution,
         reproduction, modification, adaptation, distribution, performance or
         display, infringe or misappropriate any copyright, patent, trademark,
         service mark, trade secret or other forms of proprietary rights of any
         third party. Bear Stearns shall give Predictive prompt notice of any
         such claim made against it, shall allow Predictive control of the
         defense of any such claim made against it, and shall give Predictive
         all reasonable assistance requested by Predictive in writing in
         connection therewith.

9.2      If, as a result of any such claim, any preliminary injunction or other
         injunctive relief is entered against Bear Stearns, or any temporary
         restraining order is obtained affecting Bear Stearns which materially
         restricts or in any way precludes any further use of any of the
         Deliverables, THEN Predictive shall refund to Bear



                                       5
<PAGE>

         Stearns all license fees and unused maintenance fees (on a pro-rata
         basis) paid to Predictive by Bear Stearns, and upon such refund this
         Agreement shall be deemed terminated under hereunder; provided,
         however, that the foregoing shall not apply if upon issuance of any
         such preliminary or other form of injunction or temporary restraining
         order, Predictive either:

         (a)      obtains promptly for Bear Stearns the right to continue to use
                  the Deliverables which are the subject of the claim of
                  infringement without additional cost to Bear Stearns, or

         (b)      provides without cost to Bear Stearns an equally satisfactory
                  substitute Deliverables which achieve the same objectives as
                  the Deliverables which are the subject of the claim of
                  infringement, is equally practicable and functional and does
                  not infringe any copyright, patent, trade secret or other form
                  of proprietary or intellectual property rights of third
                  parties.

SECTION 10:       TERMINATION/BANKRUPTCY

10.1     Termination For Convenience By Bear Stearns. Bear Stearns may terminate
         this Agreement or a particular Statement of Work by giving thirty (30)
         days advance written notice to Predictive. Bear Stearns shall then pay
         within (30) days all unpaid amounts that have been incurred as of the
         date of termination plus a termination charge equal to thirty percent
         (30%) of the total remaining fees that would have been due under the
         terminated Statement(s) of Work, if the remainder of the Services
         described therein had been fully performed. The remainder balance shall
         be computed by subtracting the value of paid invoices from the total
         value of the Services under the terminated Statement(s) of Work. The
         parties agree that such termination charge shall constitute
         consideration for Predictive's time, effort and expense in preparing to
         perform its obligations, hereunder, as actual damages are difficult to
         ascertain. Predictive shall promptly deliver to Bear Stearns all
         Deliverables performed for and prepaid by Bear Stearns prior to the
         termination relating to such Statement of Work.

10.2     Termination For Breach by Bear Stearns. If Bear Stearns fails to pay
         any outstanding charges within forty-five (45) days after receipt of
         written notice of delinquency, or if Bear Stearns fails to perform or
         observe any other material term or condition of this Agreement for
         forty-five (45) days after receipt of written notice from Predictive of
         such failure, Bear Stearns shall be in default and Predictive may,
         without prejudice to any other right or remedy, suspend performance
         under, or terminate in its entirety, or in relation to a particular
         Statement of Work. Any unpaid charges or other obligations accrued to
         such termination shall survive termination of this Agreement or
         Statement of Work, as applicable.

10.3     Termination For Breach by Predictive. If Predictive fails to perform or
         observe any other material term or condition of this Agreement and/or
         Statement(s) of Work for forty-five (45) days after Predictive's
         receipt of written notice from Bear Stearns of such failure and has not
         commenced performance or observance of such material term or condition
         within such 45-day period, Bear Stearns shall have the option of
         immediately terminating the Agreement and/or Statement of Work involved
         in whole or in part, without further obligation including any
         additional payments, liability or penalty of any kind.

10.4     If Predictive becomes the subject of a case commenced under Title 11 of
         the United States Code (the "Bankruptcy Code") and Predictive, as
         debtor-in-possession, or a trustee appointed for Predictive ("Trustee")
         decides to reject this Agreement and/or any Statement of Work pursuant
         to Section 365(n) of the Bankruptcy Code, then Bear Stearns, in
         addition to all rights conferred by the Bankruptcy Code and other
         applicable law, shall have the right to treat this Agreement and/or
         such Statement of Work as terminated or to retain its rights
         thereunder. If Bear Stearns decides to retain its rights under this
         Agreement and/or Statement of Work, as the case may be, then (i) on
         written request of Bear Stearns, Predictive or the Trustee shall
         provide Bear Stearns with any and all information, Deliverables and any
         other Works of Authorship held by the Trustee, Escrow Agent or
         Predictive; and (ii) Predictive or the Trustee shall not interfere with
         the rights of Bear Stearns pursuant to this Agreement including, but
         not limited to the right to obtain any information pertaining to the
         foregoing from any other entity or individual, including employees,
         consultants and former employees and consultants of Predictive.
         Predictive acknowledges and consents that the automatic stay imposed by
         Section 362 of the Bankruptcy Code shall be automatically lifted,
         modified and/or vacated to allow Bear Stearns to realize any and all of



                                       6
<PAGE>

         its rights herein. The provisions of this paragraph shall also apply in
         the event that Predictive or the Trustee has not rejected this
         Agreement or any Statement of Work. The parties hereby agree and affirm
         that the payments already paid by Bear Stearns as of the date of a
         rejection under the Bankruptcy Code, as described in the first sentence
         hereof, are full consideration for Predictive's obligation and
         undertakings under this Agreement and all applicable Statements of
         Work. These payments shall not be deemed to be royalty payments for the
         purpose of Section 365(n) of the Bankruptcy Code and if Predictive or
         the Trustee rejects this Agreement or any Statement of Work and Bear
         Stearns decides to retain its rights thereunder, Bear Stearns shall be
         relieved from its obligation to make such payments.

10.3.    Notwithstanding anything set forth in this Agreement, the assignments
         made and licenses granted in this Agreement shall survive the
         expiration or termination of the Agreement, regardless of the cause.

SECTION 11:       MISCELLANEOUS

11.1.    If any provision of this Agreement is declared or found to be invalid,
         illegal, unenforceable or void, then both parties shall be relieved of
         all obligations arising under such provision, but only to the extent
         that such provision is invalid, illegal, unenforceable or void, it
         being the intent and agreement of the parties that this Agreement shall
         be deemed amended by modifying such provision to the extent necessary
         to make it valid, legal and enforceable while preserving its intent or,
         if that is not possible, by substituting therefor another provision
         that is valid, legal and enforceable and achieves the same objective.
         Each party agrees that it will perform its obligations hereunder in
         accordance with all applicable laws, rules and regulations now or
         hereafter in effect.

11.2.    Headings are for reference purposes only.

11.3     Any notices required or permitted to be sent hereunder shall be served
         personally or by registered or certified mail, return receipt
         requested, reputable overnight delivery services such as Federal
         Express, Airborne Express or DHL, or by facsimile with confirmation of
         receipt; to the addresses listed above.

11.4.    This Agreement shall be interpreted and construed in accordance with
         the Copyright laws of the United States and the internal law of State
         of New York, without regard to the conflicts of law principles thereof,
         and any action brought in relation to this Agreement shall be brought
         in a Federal or state court in the City of New York and Licensee and
         Licensor hereby irrevocably consent to the jurisdiction of such Courts,
         and both parties hereby waiving any claim or defense that such forum is
         not convenient or proper. Each party hereby consents to service of
         process by any means authorized by New York law (other than by
         publication). Each party waives any right to trial by jury with respect
         to any dispute, suit, action or proceeding arising out of or relating
         to this Agreement or otherwise relating to the relationship of the
         parties, whether in contract, tort or otherwise.

11.5.    This Agreement may not be modified or altered except by a written
         instrument executed by both parties. The failure of either party to
         exercise in any respect any right provided for herein shall not be
         deemed a waiver of any rights. This Agreement, together with each
         Statement of Work hereunder, constitutes the entire agreement between
         the parties with respect to the subject matter hereof and supersedes
         and merges all prior proposals, understandings and all other
         agreements, oral and written between the parties relating to such
         subject matter. The rights and remedies of Bear Stearns under this
         Agreement and any Statement of Work are cumulative.

11.6.    Neither party may assign this Agreement or any Statement of Work or
         delegate any obligations hereunder or thereunder, except that
         Predictive may sub-contract some or all of its performance under the
         Agreement only with the written consent of Bear Stearns, which shall
         not be unreasonably withheld; provided, however, that all obligations
         of Predictive under this Agreement shall apply fully to any such
         sub-contractor as if it were "Predictive" under this Agreement and
         Predictive shall remain fully liable for the performance of such
         assignee or sub-contractor hereunder; and Bear Stearns may from time to
         time assign this Agreement, in whole or in part, to one or more of its
         then affiliates, and to the extent of any such assignment, the relevant
         references in this agreement to shall apply to such affiliate.

         otherwise obligates Bear Stearns to reimburse Predictive for any travel
         (including lodging, meals or similar expenses), such obligation is
         subject to the following conditions and limitations: (a) the travel
         expenses may not exceed the expense of travel to the relevant Bear

         records certain telephone lines and other communications devices going
         into or out of Bear Stearns's premises, and to the extent that any such
         monitoring and/or recording occurs relating to any telephone call and
         other communication going into or out of Bear Stearns's premises
         involving Predictive or any of its employees, agents and

CERTAIN PORTIONS OF THIS EXHIBIT HAVE BEEN OMITTED AND FILED SEPARATELY WITH
THE SECURITIES AND EXCHANGE COMMISSION, PURSUANT TO A REQUEST FOR
CONFIDENTIAL TREATMENT UNDER RULE 406 UNDER THE SECURITIES ACT OF 1933, AS
AMENDED.


                                                                   Exhibit 10.11

                          CONSULTING SERVICES AGREEMENT


THIS AGREEMENT, together with the applicable Schedule(s) attached hereto, as
such may be amended from time to time by agreement of the parties,
(collectively, the "Agreement") is made and entered into as of this 14th day of
October, 1998 by and between Predictive Systems, Inc. ("Independent Contractor")
a corporation formed under the laws of Delaware and Pershing
Division of Donaldson, Lufkin & Jenrette Securities Corporation ("Pershing"), a
Delaware Corporation, with offices at One Pershing Plaza, Jersey City, New
Jersey 07399.

1. AGREEMENT. Independent Contractor hereby agrees to perform for Pershing, and
Pershing hereby agrees to compensate Independent Contractor for, the consulting
and other services described in this Agreement and any Schedule(s) attached
hereto (the "Services"), as such Services may be further defined, expanded or
modified by Pershing's authorized personnel, all on the terms and subject to the
conditions more fully set forth below.

Nothing herein shall be deemed to constitute a partnership or a joint venture
between the parties hereto.

For purposes of this Agreement, "Assigned Person(s)" shall mean Independent
Contractor's officers, directors, employees, consultants, agents and
subcontractors performing Services hereunder.

2. STANDARD OF PERFORMANCE.

         (a) GENERAL. Independent Contractor warrants and agrees to perform the
Services diligently and with the care and judgment of an experienced
professional. Independent Contractor agrees to use diligent and determined
efforts timely to complete all Services in conformity with any specifications
and standards as may be furnished to Independent Contractor or otherwise
identified by Pershing in connection therewith.

         (b) REPORTS. At Pershing's request, Independent Contractor agrees to
promptly furnish to Pershing a written report summarizing the status of work
being performed hereunder.

         (c) SUPERVISION. Independent Contractor agrees to diligently supervise
Assigned Person(s). Subject thereto, Independent Contractor and Assigned
Person(s) agree to perform the Services under the direction of such Pershing
personnel or other Pershing independent contractors as Pershing may designate.

Except with Pershing's knowledge and express written consent, Assigned Person(s)
agree(s) to avoid any involvement or activity which may create an appearance of
impropriety or conflict. Such involvement or activity may include engaging in
any undertaking or employment, having any significant financial or other
interest (e.g., ownership of more than 1% by Assigned Person or immediate family
member), or accepting any payment, any of which actually or potentially may
compromise Assigned Person(s)' professional judgment or objectivity, or
interfere with or prevent them from serving Pershing's best interests.


<PAGE>

3. STAFFING.

         (a) GENERAL. Independent Contractor warrants that all Assigned Persons
shall have been or shall be willing to be subject to a background check
(including but not limited to a check of criminal record, work experience and
education) prior to beginning work at Pershing. For the purposes of the
foregoing, a criminal record or information indicating that the Assigned Person
may have falsified information provided to Pershing or the Independent
Contractor in the engagement process or otherwise is in all events to be
considered information about which Independent Contractor must promptly notify
Pershing. If such background check is performed by Pershing, Independent
Contractor agrees that Pershing has the right, [****].


         (b) QUALIFICATIONS. Independent Contractor agrees that Pershing may
require any [****].


         (c) NOTICE OF UNFITNESS. If Independent Contractor becomes aware that
any Assigned Person lacks the skills, knowledge and/or experience necessary to
perform the Services or which may affect his/her acceptability to Pershing,
Independent Contractor agrees promptly to notify Pershing in writing of such
information.

         (d) REQUIRED DISCLOSURE. Independent Contractor agrees to disclose to
Pershing the identity of any Assigned Person (or prospective Assigned Person)
who is an employee, significant shareholder or principal of any corporation or
legal entity other than Independent Contractor.

         (e) CONTROLLED SUBSTANCES. Independent Contractor acknowledges that
Pershing has the following rule with respect to controlled substances:
Possessing, using, purchasing, distributing, selling or having controlled
substances in your system without medical authorization during the work day, on
Pershing's premises, or while conducting Pershing business is inconsistent with
Pershing's business interest and will be grounds for disciplinary action up to
and including immediate termination. Independent Contractor agrees that Assigned
Persons shall be subject to Pershing's rules concerning controlled substances
and testing by Independent Contractor at Pershing's request for the presence of
controlled substances. A confirmed positive result of testing of any Assigned
Person, or the refusal by any to submit to testing, will, among other things,
result in such individual being deemed unsuitable by Pershing. Any such
individual will immediately be barred from Pershing's premises, and Pershing
reserves all rights it may have at law or in equity.

         (f) REPLACEMENT PROCEDURE. If the replacement of any Assigned Person
is necessary for any reason, Independent Contractor agrees to submit the
names and qualifications of replacement candidates for Pershing Pershing's
approval within [****] following the date on which Independent Contractor (i)
becomes aware of such Assigned Person's prospective unavailability or (ii) if
applicable, receives a notice from Pershing demanding such replacement. Any
replacement Assigned Person agrees to participate in such orientation as
Pershing shall determine appropriate. Pershing shall have no obligation to
compensate


**** Represents material which has been redacted and filed separately with
the Commission pursuant to a request for confidential treatment pursuant to
Rule 406 under the Securities Act of 1933, as amended.


                                       2
<PAGE>

Independent Contractor hereunder for any activities (including Services)
performed by a replacement Assigned Person during such orientation period.

Independent Contractor agrees to use its best efforts to minimize any delay or
disruption to Pershing resulting from the replacement or removal of any Assigned
Person.

4. INDEPENDENT CONTRACTOR STATUS. It is the express intention of the parties
that neither Independent Contractor nor any Assigned Person is an employee,
agent (except as set out herein) or partner of Pershing. Nothing in this
Agreement shall be interpreted as creating the relationship of employer and
employee between the Independent Contractor or Assigned Person and Pershing.
Independent Contractor agrees to be solely responsible for the payment of
compensation to Assigned Person(s). Assigned Person(s) shall not be entitled to
participate in or directly receive benefits pursuant to the provisions of any
Pershing employee benefit plans or policies. Pershing shall not be responsible
for payment of workers' compensation, disability benefits, unemployment
insurance or for withholding income taxes or social security payments for any
Assigned Person. Independent Contractor agrees to be solely responsible for, and
agrees to duly perform, all such payment and withholding obligations as may be
required by law.

5. PERSHING FACILITIES AND EQUIPMENT.

         (a) EQUIPMENT. Subject to Pershing's prior written approval, it may
become necessary for Assigned Persons to utilize Pershing equipment (including
software) away from Pershing's premises for Pershing's business purposes. In
such event, Independent Contractor and the Assigned Person(s) hereby agree to
the following:

         (i)      each agrees to exercise at least reasonable care in the use of
                  the equipment;

         (ii)     upon the termination of the engagement with Pershing, or at
                  such earlier time as Pershing shall demand, the Assigned
                  Person(s) shall surrender the equipment to Pershing in as good
                  order and condition as the same now is in, reasonable wear and
                  tear resulting from the proper use thereof alone excepted;

         (iii)    not to surrender possession of the equipment or permit the use
                  of the equipment by anyone other than the Assigned Person
                  without the prior written consent of Pershing;

         (iv)     to reimburse Pershing should Pershing incur any charge by
                  reason of Independent Contractor's use of the equipment for
                  any purpose other than the business of Pershing. Pershing may
                  deduct the amount of such charge from any amounts due to
                  Independent Contractor from Pershing by reason of this
                  Agreement or, if no such amounts are due Independent
                  Contractor, Pershing may bill Independent Contractor
                  accordingly;

         (v)      not to install software on the equipment unless it has been
                  duly licensed to Pershing. As a matter of Pershing policy,
                  each Assigned Person is required to respect any and all
                  copyrights, patents, trade secrets and



                                       3
<PAGE>

                  trademarks of any other entity. Each Assigned Person shall be
                  a custodian of third party propriety information that may have
                  been lawfully provided to Pershing. Accordingly, third party
                  software may not be used for personal benefit or disclosed to
                  other parties (or used for any purposes beyond the scope of
                  the license to Pershing). Copies should not be made for any
                  reason, unless permitted by the license agreement. Moreover,
                  the Assigned Person may not make reference to (i.e., copy) the
                  work of third parties in the development of software systems
                  for Pershing. Assigned Persons who make, acquire or use
                  unauthorized copies of computer software will have their work
                  orders terminated without limiting Pershing's other rights it
                  may have at law or in equity.

         Unauthorized or otherwise personal information should not be installed,
         created, sorted or transmitted using the equipment. Pershing will treat
         any personal information or files that are stored, processed, or
         transmitted using the equipment as Pershing's property and may copy,
         access and disclose any such information or files in accordance with
         its business needs and polices. This includes, without limitation, the
         right to conduct a software audit of the equipment loaned to Assigned
         Person, at any off-site location, including his/her residence.

         (b) FACILITIES. Pershing agrees to provide Independent Contractor with
such access to office space and related information processing and
telecommunications systems, storage media and other systems, equipment and
facilities ("Facilities") as Independent Contractor may reasonably require to
perform its obligations hereunder.

Pershing's facilities are to be used by Assigned Person(s) solely for the
conduct of Pershing's business and performance of the services and for no other
purpose. Independent Contractor and Assigned Person(s) hereby acknowledge(s) and
agree(s) that Pershing may treat as Pershing's property and may, without
restriction or prior notice, copy, access, modify, destroy or disclose in
accordance with its business needs and policies, any information or files,
whether or not of a personal nature or unrelated to the Services, that any
Assigned Person(s) may create, copy, store, process, receive or transmit using
Pershing's facilities.

Pershing shall have the right, in its discretion, at any time and for any
business purposes, to exclude or eject, either temporarily or permanently, any
Assigned Person(s) from its premises.

         (c) WORK POLICY. Except as otherwise specified by Pershing, Independent
Contractor and Assigned Person(s) agree to observe the working hours, rules and
holiday schedule of Pershing while working on Pershing's premises. Adherence to
such working hours, rules and holiday schedules shall not constitute
justification for failure to timely complete any Services, nor shall adherence
to Pershing's rules and schedule create an employment relationship between
Pershing and Independent Contractor or Assigned Person(s). Assigned Person(s)
shall not be entitled to receive any benefits or payments which Pershing may
provide to its employees.

         (d) SECURITY. Independent Contractor agrees to observe and comply with
(and agrees to cause Assigned Person(s) to observe and comply with) all
policies, measures, procedures and regulations governing the workplace that
Pershing may establish from time to time, including



                                       4
<PAGE>

without limitation those relating to security, safety, health and decorum.
Without limitation on the foregoing, if Pershing maintains a log book or other
means of tracking entry and exit at its premises where Services are performed,
Assigned Person(s) shall diligently record the date and time of his/her arrival
at and departure from the premises, and any other information that Pershing may
reasonably request. Upon request at any time by Pershing security personnel,
Assigned Person(s) shall display any identification cards furnished by Pershing
or otherwise establish their identity to the satisfaction of such security
personnel.

         (e) COMPUTER CENTER. Independent Contractor agrees not to break, bypass
or circumvent. Or attempt to break, bypass or circumvent, any security system of
Pershing or obtain, or attempt to obtain, access to any program or data other
than that which Independent Contractor owns, is developing or testing pursuant
hereto or to which it has expressly been granted access by Pershing in writing.

In the event that Independent Contractor obtains access to any such program or
data, it shall promptly notify Pershing of such access and shall cooperate as
requested by Pershing in any investigation thereof or prosecution resulting
therefrom. Independent Contractor shall not, in any manner whatsoever, use such
program or data, or disclose such program or data to any third party.
Independent Contractor agrees to establish appropriate procedures to limit
access to Pershing facilities by Assigned Persons to those having a need for
such access in connection with the Services and in accordance with the
limitations set forth herein and for the protection of Pershing Confidential
Information (as defined in Section 8 herein). Independent Contractor agrees to
cause Assigned Person(s) to comply with these procedures.

6. TERMINATION.


         (a) GENERAL. Either party may terminate this Agreement at any time
and for any reason upon thirty (30) days' advance written notice to the
other, setting forth the effective date of such termination.



If either party fails to discharge a material obligation or to remedy a
material default under this Agreement, the other party may give written
notice specifying the material obligation or material default and indicating
an intent to terminate this Agreement if the material obligation is not
discharged or the material default is not corrected. The party receiving such
notice shall have fourteen (14) days from the date of receipt of such notice
to discharge such material obligation or cure such material default. If the
material obligation is not discharged or the material default is not
corrected by the end of such fourteen (14) day period, the other party may
terminate this Agreement, effective immediately upon written notice to the
defaulting party given at any time after the end of such period, provided
that the material obligation has not been discharged or the material default
is continuing on the date of such notice. Notwithstanding the foregoing,
Pershing may request any Assigned Person to leave its premises immediately in
the event of any perceived risk during the fourteen (14) day period, without
responsibility for payment beyond the actual time worked.


         (b) ORDERLY TERMINATION. In the event this Agreement is terminated for
any reason, including, without limitation, default by either party, and
notwithstanding any claim by Independent Contractor for amounts unpaid and in
dispute by Pershing, Independent Contractor




                                       5
<PAGE>

agrees to provide such information, cooperation and assistance to Pershing or
its designee, as Pershing may reasonably request to assure the orderly
termination of this Agreement and the orderly transfer to Pershing or its
designee of materials relating to, and responsibility for providing, the
Services or services related thereto. Notwithstanding any other provision
hereof, Independent Contractor's obligations to Pershing under this Agreement
shall not terminate until completion of the orderly transfer contemplated by
this section (notwithstanding the fact that Independent Contractor's other
obligations may survive longer as provided by this Agreement).

         (c) RETURN OF MATERIALS. Upon termination, Independent Contractor and
Assigned Person(s) are obligated to return to Pershing all copies of such
materials, documentation. programs, drawings, specifications and work product in
its possession or stored in any computer system and to purge all such computer
systems of such copies once copies of same are provided to Pershing. In
addition, Independent Contractor and its Assigned Person(s) are obligated to
immediately return any security identification pass provided by Pershing.

7. INDEMNITY AND INSURANCE.

         (a) GENERAL INDEMNITY. Independent Contractor agrees to defend,
indemnify and hold harmless Pershing and its affiliates and their respective
partners, directors, principal, agents, employees, and officers (collectively,
"Pershing Indemnitees") from any loss, damage, liability, cost or expense
resulting or caused by (i) any negligent act or omission or willful misconduct
of Independent Contractor or any Assigned Person; (ii) any breach or default by
Independent Contractor in the performance of this Agreement; (iii) claims for
personal injury or property damage arising out of Independent Contractor's
performance of the Services; or (iv) any claim by an employee or subcontractor
of Independent Contractor against Independent Contractor and/or Pershing
Indemnitees.

         (b) INSURANCE REQUIREMENT. Without limiting the scope of the foregoing
indemnification, Independent Contractor agrees to provide to Pershing, within
ten (10) days after the date hereof, a certificate of insurance endorsing
Pershing as an additional named insured to Independent Contractor's insurance,
evidencing the following insurance coverage in the following minimum amounts:

<TABLE>
<CAPTION>
Workers' Compensation                     Statutory limits
<S>                                       <C>
General Liability                         $1,000,000 per Occurrence
Automobile Liability                      $1,000,000 per Occurrence
Errors and Omissions                      $1,000,000
</TABLE>

The certificate of insurance referred to above shall also state that each
insurance policy is in full force and effect, that the premiums in respect
thereof have been paid in full, and that such policy may not be canceled or
materially changed unless Pershing shall receive thirty (30) days advance
written notice in the event of such cancellation of or material change in the
policy. For so long as Independent Contractor is performing Services hereunder,
at least thirty (30) days before the expiration of any such insurance policy,
Independent Contractor agrees to deliver to Pershing certificates of insurance
attesting to the renewal of such insurance. Receipt by Pershing of any
certificate of insurance which does not conform to the requirements of this
section shall not



                                       6
<PAGE>

relieve Independent Contractor of its obligation to provide insurance conforming
to the requirements hereof.


         (c) ADVERSE TAX INDEMNITY. In the event that the Internal Revenue
Service, any state or local government agency or any other applicable taxing
authority determines that any Assigned Person is an employee of Pershing for
the purpose of any tax liability (including, without limitation, liabilities
relating to employee withholdings and payroll taxes), Independent Contractor
agrees to reimburse Pershing upon demand for, and shall otherwise defend,
indemnify and hold harmless Pershing from and against, all losses, claims,
damages, liabilities, costs and expenses (including but not limited to taxes,
fees, imposts, penalties, interest, and reasonable attorneys' and
accountants' fees), as incurred and on an after tax basis, based on or
arising from or in connection with any such determination.


         (d) SURVIVAL. The indemnification provisions in this Agreement shall
remain operative and in full force and effect, regardless of the termination of
this Agreement, and shall survive any such termination.

8. DEFINITION OF CONFIDENTIAL INFORMATION. Information disclosed by Pershing,
including but not limited to, information learned by the Independent Contractor
and Assigned Persons from Pershing's employees, agents or through inspection or
discussion of Pershing's property, that relates to Pershing's or a customer's
methods, trade secrets, programs, operations, customers, products, services,
designs, business plans, business opportunities, finances, research,
development, know-how, personnel or third-party confidential information and the
terms and conditions of this Agreement, will be considered and referred to

breach on the part of the Independent Contractor or Assigned Person; (ii) the
Independent Contractor or Assigned Person can demonstrate to have had rightfully
in its possession prior to exposure to it; (iii) is independently developed by
the Independent Contractor or Assigned Person without the use of any
Confidential Information; or (iv) the Independent Contractor or Assigned Person
rightfully obtains from a third party who has the right to transfer or disclose
it.

All Confidential Information, and any Derivative thereof, whether created by the
Independent Contractor, Assigned Person or Pershing, remains the property of
Pershing and no license or other right to Confidential Information is granted or
implied hereby. For purposes of this Agreement, "Derivatives" shall mean: (i)
for copyrightable or copyrighted material, any translation, abridgment, revision
or other form in which an existing work may be recast, transformed or adapted;
(ii) for patentable or patented material, any improvement thereon; and (iii) for
material which is protected by trade secret, any new material derived from such
existing trade secret material, including any new material which may be
protected by copyright, patent and/or trade secret.

9. NON-DISTRIBUTION/NON-DISCLOSURE OF CONFIDENTIAL INFORMATION. The Independent
Contractor further covenants and agrees that it: (i) will neither copy,
disclose, publish or distribute Confidential Information to anyone other than
those to whom such disclosure is authorized or necessary for performance of this
Agreement; (ii) will take reasonable




                                       7
<PAGE>

precautions to prevent any unauthorized use, disclosure, publication or
dissemination of Confidential Information; (iii) will not, during the
contractual relationship with Pershing, nor at any time thereafter, directly or
indirectly disclose to others and/or use for its own benefit or for the benefit
of others, Confidential Information, including, but not limited to: trade
secrets, customer lists, employee and prospective employee information,
proprietary software products, any financial information pertaining to
Pershing's business or that of any of its clients, consultants, licensees or
affiliates, acquired by it during the period of its employment, except to the
extent necessary in the ordinary course of performing its duties with respect to
Pershing; (iv) upon termination of its contract with Pershing, the Independent
Contractor will return Confidential Information, and any copies or compilations
thereof and certify to Pershing that it no longer has any rights to such
materials or information, and it covenants that the original and all copies of
such materials and information have been returned to Pershing. In the event of a
breach or threatened breach by the Independent Contractor of the provisions of
this paragraph, Pershing shall be entitled, in addition to all other remedies
available, to an injunction restraining the Independent Contractor from
disclosing any such information or knowledge.

10. PERMITTED DISCLOSURE. The Independent Contractor only may disclose
Confidential Information if required by a judicial or governmental request,
requirement, order or subpoena, and provided that the Independent Contractor
gives Pershing notice of such request, requirement, order or subpoena within
[****] of receipt by Independent Contractor.

11. WARRANTIES. Independent Contractor represents and warrants that: (a) it has
full and unrestricted right to disclose any information, knowledge or data
disclosed by it to Pershing in the performance of this Agreement; (b) it is free
to undertake the Services provided for in this Agreement, and there is no
conflict of interest between Independent Contractor's performance of this
Agreement and any existing obligation Independent Contractor has to other
parties; (c) performance of this Agreement will not violate any non-compete or
non-disclosure provision (or any substantially similar provision) of any
contract or agreement previously entered into by Independent Contractor; and (d)
will not disclose to Pershing or attempt to induce Pershing to use any
Confidential Information or material to which Pershing is not entitled.

12. WORK FOR HIRE. The Independent Contractor will immediately disclose to
Pershing any and all improvements and inventions that it makes solely, or
jointly or commonly with others during the term of its contractual relationship
with Pershing, with respect to:

         (a)      methods, processes or apparati relating to the services
                  performed by Pershing; and/or

         (b)      any character of services sold or used by Pershing.

13. ASSIGNMENT OF RIGHT, TITLE AND INTEREST. The Independent Contractor agrees
to immediately assign, transfer and convey to Pershing its entire right, title

inventions and in and to all letters patent that may be issued upon such
applications.

14. NECESSARY STEPS/PROCEDURES FOR ASSIGNMENT. The Independent Contractor agrees
to immediately:

         (a)      sign any and all instruments necessary for the filing and
                  processing of any applications for letters patent of the
                  United States, or of any foreign country, that Pershing may
                  desire to file upon such inventions as are specified herein;

         (b)      sign all instruments necessary for reviving or renewing any of
                  such applications as may become necessary or desirable; and

         (c)      sign all instruments necessary to the filing and processing of
                  any continued applications, or reissue applications, that may
                  subsequently appear to be necessary or desirable to render
                  such inventions as are mentioned herein effective and of full
                  force for the purposes of Pershing.

15. HIRING. Independent Contractor agrees that it will not directly or
indirectly hire, solicit or otherwise contract for services with any Pershing
employees or other Pershing contractors or their employees, agents, consultants
or subcontractors during the term of this Agreement and for a period of one (1)
year following the termination thereof. The Pershing Division of Donaldson,
Lufkin & Jenrette Securities Corporation agrees that it will not knowingly
solicit for employment without prior written consent any predictive employee,
consultant or subcontractor during the term of this Agreement and for a period
of one (1) year following the termination thereof.

16. LIMITATION OF LIABILITY. INDEPENDENT CONTRACTOR AGREES THAT NO PERSHING
INDEMNITEES SHALL BE LIABLE FOR ANY LOST PROFITS OR SPECIAL, INDIRECT,
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING UNDER THIS AGREEMENT FOR ANY CAUSE
WHATSOEVER, REGARDLESS OF THE FORM OF ACTION, WHETHER IN CONTRACT, TORT OR
STRICT LIABILITY, AND WHETHER OR NOT ANY PERSHING INDEMNITEE HAD BEEN ADVISED OF
OR COULD HAVE FORESEEN THE POSSIBILITY OF SUCH DAMAGES. NO PERSHING INDEMNITEE
SHALL BE LIABLE FOR ANY LOSS, COST, EXPENSE, CLAIM, INJURY OR DAMAGE TO
INDEPENDENT CONTRACTOR OR ITS PROPERTY OR PERSONNEL EXCEPT LOSSES, COSTS,
EXPENSES, CLAIMS, INJURIES OR DAMAGES CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF A PERSHING INDEMNITEE.

Neither party to this Agreement shall be liable to the other for consequential,
incidental or indirect damages, including lost profits arising from default in
the performance of its respective obligations under, or otherwise in connection
with, this Agreement. This limitation applies regardless of the form of action,
whether in contract or tort. However, the provisions of this Section shall not
apply to Independent Contractor's obligation to indemnify any indemnified party.

17. FORCE MAJEURE. In no event shall either party be liable to the other for any
delay or failure to perform hereunder, which delay or failure to perform is due
to causes beyond the control of said party, including but not limited to, acts
of God, acts of the public enemy, acts of the United States of America, or any
state, territory or political division of the United States of



                                       9
<PAGE>

America, or of the District of Columbia, fires, floods, epidemics, quarantine
restrictions, strikes or any other labor disputes and freight embargoes. In
every case the delay or failure to perform must be beyond the control and
without the fault or negligence of the party claiming excusable delay, and the
party claiming excusable delay must promptly notify the other party of such
delay. Performance times under this Agreement shall be considered extended for a
period of time equivalent to the time lost because of any delay which is
excusable under this Section; provided, however, that if any such delay
continues for a period of more than five (5) business days, the party not
claiming excusable delay shall have the option of terminating this Agreement
upon notice to the party claiming excusable delay.

18. ASSIGNMENT. This Agreement shall inure to the benefit of, and be binding
upon, the respective successors and assigns, if any, of the parties hereto.
Neither party shall assign its rights under this Agreement without the prior
written consent of the other party, such consent not to be unreasonably
withheld.

19. NON-USE OF PERSHING NAME. Independent Contractor agrees that it will not, in
the course of performance of this Agreement, or thereafter, use Pershing's name
in any advertising or promotional media without the prior written consent of
Pershing.

20. COMPLIANCE WITH LAWS. Independent Contractor warrants that no laws,
regulations or ordinances of the United States, or any state or government
authority or agency, have been violated, including the Fair Labor Standard Act,
as amended, in the performance of the Services hereunder, and agrees to
indemnify and hold Pershing harmless from any and all claims arising out of
breach by Independent Contractor of its obligations hereunder. Independent
Contractor agrees to, at its own expense, comply with all other laws, rules and
regulations and assume all liabilities or obligations imposed by such laws,
rules and regulations with respect to Independent Contractor's performance.

21. REMEDIES. Independent Contractor acknowledges that any failure to perform
its obligations under this Agreement shall cause Pershing irreparable injury not
compensable by money damages, for which Pershing will not have an adequate
remedy at law. Accordingly, if Pershing institutes an action or proceeding to
enforce the provisions of this Agreement, Pershing shall be entitled, without
the posting of any bond or security, to such injunctive or other equitable from
a court of competent jurisdiction as may be necessary or appropriate to require
Independent Contractor to perform such obligations. The foregoing shall be in
addition to, and without prejudice to, such rights as Pershing may have, subject
to the express provisions of this Agreement, at law or in equity.

Without limiting Pershing's rights in any way, the maximum liability which
Pershing may incur to Independent Contractor for damages of any kind (whether
direct or otherwise), [****]. Independent Contractor's exclusive remedy for
any claim arising out of, connected with, relating to, or resulting from this
Agreement and the obligations under this Agreement are limited to a claim for
the damages set out in this section. This limitation shall apply regardless
of whether the Independent Contractor brings a claim in


**** Represents material which has been redacted and filed separately with
the Commission pursuant to a request for confidential treatment pursuant to
Rule 406 under the Securities Act of 1933, as amended.


                                       10
<PAGE>

contract, equity or tort (including but not limited to claims for negligence and
willful misconduct).

All remedies available to either party for breach of this Agreement are
cumulative and may be exercised concurrently or separately, and the exercise of
any one remedy shall not be deemed an election of such remedy to the exclusion
of other remedies.

22. INVOICES, FINANCIAL RECORDS AND AUDIT CAPABILITY. Independent Contractor
agrees to bill Pershing by monthly invoice as of the last calendar day of the
month addressed to:

         Ms. Sandra Baptiste
         Pershing
         19 Vreeland Road
         Florham Park, NJ 07932

and agrees to maintain full and detailed records of all items billed to Pershing
under this Agreement. Pershing reserves the right to audit and copy, during
regular business hours, the records pertaining to the scope of this Agreement,
including the records maintained at Independent Contractor's office which may
provide Pershing with evidence that reveals any excessive charges against
Pershing or noncompliance with the terms and conditions herein, for a
[****] period after the termination of this Agreement. If such
audit reveals any excessive charges against Pershing, such excessive charges
shall be refunded to Pershing immediately upon written notification by Pershing
to Independent Contractor, notwithstanding that Pershing may have previously
paid such excessive charges for accepted services. Independent Contractor shall
be given thirty (30) days to refute or approve the findings of any such audit.
Moreover, Independent Contractor agrees to maintain full and detailed records of
all sales tax charged to Pershing and paid to the Government by Independent
Contractor. Pershing reserves the right to copy and audit these tax records
during regular business hours, including any records maintained at Independent
Contractor's office pertaining to sales tax billed to Pershing, for a period of
[****] after the termination of this Agreement.

23. SEVERABILITY. In the event any one or more of the provisions of this
Agreement shall, for any reason, be held to be invalid, illegal or
unenforceable, the remaining provisions of this Agreement shall be unimpaired
and shall continue in full force and effect, and the invalid, illegal or
unenforceable provision shall be replaced by a mutually acceptable provision,
which, being valid, legal and enforceable, comes closest to the intention of the
parties underlying the invalid, illegal or unenforceable provision.

24. WAIVER. The failure of either party to insist upon the performance of any
terms or conditions of this Agreement or to exercise any right or privilege
conferred in this Agreement or the waiver of enforcing penalties resulting from
any breach of any terms and conditions of this Agreement, shall not be construed
as waiving any such terms, conditions, rights or privileges, but the same shall
continue and remain in full force and effect as if no such forbearance or waiver
had occurred.

be binding upon the parties if it has been made in writing and signed by
authorized representatives of both parties.

26. GOVERNING LAW. This Agreement, and any amendments thereto, shall be governed
by the laws of the State of New York without giving effect to those provisions
governing conflicts of law. By entering into this Agreement Independent
Contractor consents to personal jurisdiction in the courts of the State of New
York.

27. ARBITRATION. The parties agree and acknowledge that any dispute, controversy
or claim, whether statutory or common law, arising out of this Agreement or the
business relationship between Independent Contractor and Pershing, or the
termination of that relationship, included but not limited to, any claims
alleging breach of contract, or any violation of any provision of this Agreement
shall be submitted and finally settled by arbitration in accordance with the

         employees of First Union within the meaning or application of any
         federal, state, or local laws or regulations. Supplier shall be

         its employees in connection with the services performed hereunder, and

         of 1973 and the Vietnam Era Veterans' Readjustment Assistance Act
         of 1974, which are incorporated herein by reference. In the event
         that and at such time as First Union requests, Supplier shall furnish
         to First Union written certification that Supplier is in compliance
         with Executive Order 11246 and applicable regulations thereunder. Both
         parties certify that they do not and shall not maintain facilities for
         their employees in a segregated manner or permit their employees to
         perform their services at any location under their control where
         segregated facilities are maintained, and agree to obtain similar
         certifications from any subcontractors.

21.      Non-Solicitation of Employees: Both Supplier and the First Union agrees
         not to directly solicit employment of each other" employees directly
         associated with this Agreement during the term hereof and for a period
         of one (1) year thereafter.

22.      Confidential Information: Each party agrees that information concerning
         the other party's business (including that of all corporate affiliates
         and subcontractors) is "Confidential Information" and shall be
         maintained in confidence and not disclosed, used or duplicated, except
         in accordance with this Agreement. Confidential Information may
         include, without limitation, list of customers, business volumes or
         usage , financial information, pricing information, information related
         to mergers or acquisitions, software, software documentation, and
         information concerning business plans or business strategy. Each party
         may use Confidential Information of the other only in connection with
         performance under this Agreement. The parties shall not copy
         Confidential Information or disclose Confidential Information to
         persons who do not need Confidential Information in order to perform
         under this Agreement. Confidential Information shall be returned to the
         party seeking to protect such information upon request of the other
         party. Confidential Information does not include information that is
         (i) generally known or available to the public, (ii) not treated as
         confidential by the party claiming information to be confidential,
         (iii) was already known to Supplier or in Supplier's procession, (iv)
         Supplier can reasonably demonstrate was developed by Supplier without
         making use of First Union Confidential Information (which may
         include providing other customers of Supplier having network
         environments similar to that of First Union with solutions similar to
         those provided by it to First Union), or (v) Supplier rightfully
         received from a third party without knowledge of violation of any
         obligation of confidentiality. Nothing contained in this Section 22 or
         otherwise shall prohibit Supplier from making disclosure of
         Confidential Information to the extent required by law, rule or
         regulation, provided that Supplier shall give First Union prior notice
         as to the nature of the required disclosure so as to afford First Union
         the opportunity to challenge the need for such disclosure. Supplier
         shall not advertise, market or otherwise make known to others any
         information relating to the subject matter of this Agreement, including
         mentioning or implying the name of First Union. If requested by First
         Union any employee, representative, agent or subcontractor of
         Supplier's shall enter into a non-disclosure agreement with First Union
         to protect the Confidential Information of First Union satisfactory to
         First Union. A breach of either party's confidentiality obligations or
         the use by Supplier of First Union's name without prior consent may
         cause First Union to suffer irreparable harm in an amount not easily
         ascertained. The parties agree that such breaches whether threatened or
         serious, will give



                                       7
<PAGE>

         the non-breaching party the right to terminate this Agreement
         immediately, obtain equitable relief, i.e., obtain an injunction to
         restrain such disclosure or use, and pursue all other remedies said
         party may have at law or in equity. The provisions of this section
         shall survive the termination of this Agreement.

23.      Use of Name: Neither party shall use the name of the other for
         advertising or other such purposes without the prior written approval
         of the other party.

24.      First Union's Instructions: During the term of the Agreement, Supplier
         shall cause its employees and agent to obey all reasonable instructions
         and directions issued by First Union concerning the First Union's
         business operations when Supplier's employees and agents are on First
         Union's premises.

25.      Change Orders: Supplier shall promptly evidence its acceptance of each
         Change Order by promptly executing the Acceptance Copy of such Change
         Order and returning such Acceptance Copy to First Union. Supplier shall
         promptly notify First Union of any objections to the Change Order and
         Supplier's failure to timely object shall constitute acceptance of the
         Change Order.

26.      Audits: The audits personnel of First Union, as well as examiners and
         representatives of First Union's regulatory agencies, will have the
         right to make such audits, examinations and inspections of Supplier's
         financial records and procedures as maybe reasonably relevant to
         Supplier's compliance with its obligations under this Agreement,
         following reasonable prior notice and conducted so as to minimize any
         interference with Supplier's business. Supplier may require such
         persons to provide reasonable evidence of their authority before being
         admitted to Supplier's facilities.

27.      Force Majeure: In the event that either party is unable to perform any
         of its obligations under this agreement, or to enjoy any of its
         benefits because of fire, natural disaster, action or decrees
         governmental bodies (a "Force Majeure Event"), the party who has been
         so affected shall immediately give written notice to the other party
         and shall do everything possible to resume performance. Upon receipt
         of such notice, all obligations under this Agreement shall be
         immediately suspended. If the period of nonperformance exceeds
         thirty (30) days from the receipt of notice of the Force Majeure Event,
         the party whose ability to perform has not been so affected, may by
         giving written notice, terminate this agreement. Delays in delivery
         due to Force Majeure Events shall automatically exceed the delivery
         date for a period equal to the duration of such Events, any warranty
         period affected by a Force Majeure Event shall likewise be extended
         for a period equal to the duration of such Force Majeure Event. As
         applied to this section and to determine whether an event is wholly
         beyond control of a party, strikes, slowdowns or other labor related
         delays are not Force Majeure Events.

28.      Limitation of Liability: Neither First Union nor Supplier shall be
         liable to the other party for any consequential, incidental or
         punitive damages. This limitation shall not diminish Supplier's
         obligation to indemnify, hold harmless and defend First Union under
         the express terms of this Agreement. WITHOUT LIMITING THE FOREGOING,



                                       8
<PAGE>

         SUPPLIER MAKES NO EXPRESS OR IMPLIED REPRESENTATIONS WITH RESPECT TO
         ITS PERFORMANCE OF THE SERVICES HEREUNDER OR ANY DELIVERABLES
         CONTEMPLATED HEREBY, INCLUDING, WITHOUT LIMITATION, ANY REPRESENTATION
         OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. In performing
         the evaluation of risk contemplated by the Statement of Work attached
         hereto, Supplier will perform certain procedures referred to in the
         Statement of Work in an attempt to identify certain risks referred to
         therein and to develop estimates as to their probability and risk
         potential, based in part on information supplied by First Union.
         Supplier will also utilize certain publicly available information in
         performing the Services, but makes no representation or warranty with
         respect thereto or with respect to my analysis based thereon. While
         Supplier believes that the procedures to be performed by it provide a
         reasonable method of attempting to analyze and qualify certain risk,
         there can be no assurance that all applicable risks will be identified
         or that any such risk can be adequately qualified, and Supplier makes
         no representation or warranty with respect to any risk identification
         or qualification made or delivered by it. In no event shall Supplier
         have any liability for any loss or harm suffered by First Union arising
         out of or relating to any such risks or the failure to identify or
         accurately quantify any thereof.

29.      Future Acquisitions: If during the term of this Agreement, First Union
         shall acquire control of any entity which is under an existing contract
         with Supplier that covers or relates to the subject matter of the
         Agreement, First Union, at its option, may keep the acquired entity's
         existing contract in effect until the date of termination of the
         existing contract, after which, such acquired entity may receive the
         benefits of this Agreement, or may immediately cancel such existing
         contract after which such acquired entity may receive the benefits of
         this Agreement.

30.      Term: The term of this Agreement shall commence on the Effective Date,
         and end on date on which all Services to be performed under the
         Statement(s) of Work issued hereunder are completed.

31.      Termination for Convenience: First Union may terminate this Agreement
         at any time by providing at least thirty (30) days written notice of
         termination to Supplier.




32.      Termination for Cause: If either party materially or repeatedly
         defaults in the performance of any of its duties or obligations
         hereunder (including defaults for which specific remedies, are provided
         herein), and said default is not substantially cured within thirty (30)
         days after written notices specifying the default is given to the
         defaulting party, or, with respect to those defaults that cannot
         reasonably be cured within thirty (30) days if the defaulting party
         fails to provide in writing within thirty (30) days to the party not
         in default a reasonable plan and completion date for curing such
         default and thereafter proceed with all due diligence to substantially
         cure the same in accordance with such plan and by such completion date,
         then the party not in default may, by giving written notice thereof to
         the defaulting party, terminate this Agreement as of the date specified
         in such notice of termination. If either party becomes or is declared
         insolvent or bankrupt, is the subject of any proceedings relating
         to its liquidation or insolvency






                                       9

         or for the appointment of a receiver for it, makes an assignment for
         the benefit of all or substantially all of its creditors, or enters
         into an agreement for the composition, extension, or readjustment of
         all or substantially all of its obligations, then the other party may,
         by giving written notice thereof to such party, terminate this
         Agreement as of a date specified in such notice of termination. If any
         of the insurance coverages or policies required to be maintained by
         Supplier under this Agreement is terminated, lapses or for any reason
         does not remain in full force and effect, or any such coverage or
         policy is replaced or partially modified without the prior written
         consent of First Union, then First Union may, by giving written notice
         thereof to Supplier, terminate this Agreement upon the date specified
         in the notice, which date may be the date of the notice.

33.      Mandatory Arbitration & Applicable Law: Any dispute, claim or
         controversy arising out of, connected with or relating to this
         Agreement shall be resolved by binding arbitration administered and
         conducted under the Commercial Arbitration Rules of the American
         Arbitration Association and Title 9 of the United States Code. The
         prevailing party in any judicial action or arbitration shall be
         entitled to reimbursement from the other party for costs, filing fees,
         arbitration filing fees, reasonable pretrial, trial and appellate
         attorney's fees, witness fees, expert fees, arbitration panel fees,
         and travel fees. A judgment upon the arbitration award may be entered
         in any court having jurisdiction. Any arbitration hearing shall take
         place at Charlotte, North Carolina. Nothing in this section, however,
         shall prevent either party from seeking equitable relief from a court
         of competent jurisdiction for the other party's breach of the
         Confidential obligation or infringement of intellectual property
         rights and any proprietary sections of this Agreement. The Agreement
         shall be governed by the laws of North Carolina.

34.      Subcontracts and Assignment: Supplier shall not assign, in whole or
         part, any of its obligations under this Agreement without First Union
         written consent. First Union may assign any benefits or obligations
         under this Agreement to any "affiliate" (as defined in 11 U.S.C.
         101(2)) of First Union. The assignor under such assignment by First
         Union shall remain liable under the Agreement. Supplier shall not
         subcontract any portion of its performance obligations under
         an Agreement without First Unions prior written approval of
         the subcontractor.

35.      Miscellaneous: Termination of this Agreement shall not release either
         party form their respective obligations hereunder with regard to
         products or services already delivered or performed, including, without
         limitation, obligations of payment, warranty, and from the
         confidentiality and indemnity provisions hereof. Any invalidity in
         whole or in part, or any provision of this Agreement shall not affect
         the validity of any other of its provisions. No term or provision
         hereof shall be deemed waived and no breach executed unless such waiver
         or consent shall be in writing and signed by the party claimed to have
         waived or consented. Failure to exercise a right or remedy at law
         granted hereunder shall not be deemed a waiver of such right or remedy.
         Failure to claim default hereunder shall not waive any default.

36.      Relationship Between the Parties: The services of Supplier are to be
         rendered as an Independent contractor, and Supplier is not an employee,
         agent, or partner of First Union.

other products under Section 3.2, on the basis generally of the anticipated
volume levels as reflected in Cabletron's initial commitment. Predictive will

implementation schedule relating to the ISRA product described above. The
parties shall in good faith mutually agree upon and attach to this Agreement,
as an addendum to Schedule 3.5, a detailed product intake and implementation

included under this Agreement after the date hereof. Predictive will use its
reasonable best efforts to commence work on a committed Assessment Project
within [****] after being advised by Cabletron of the Customer's execution
and delivery of the commitment; PROVIDED, HOWEVER, that predictive shall have
up to [****] to commence such work, due to unanticipated staffing shortages
or other reasonably unforeseen circumstances, it is not practicable to do so

Committee and shall be modified upon written agreement of a majority of the
members thereof, subject to the parties' respective operational and risk
management policies.

         3.7 The parties recognize that in order to carry out its duties
under this Agreement, Predictive will be required to put substantial effort
into the development of the various Assessment Products and build and
maintain a sizable additional marketing and service-delivery capability.
Accordingly, Cabletron hereby commits to and agrees to pay certain
non-refundable amounts to Predictive in accordance with this Section 3.7, in
consideration of Predictive's entering into this Agreement and making the

Payment") will be paid upon delivery by Predictive of the applicable
Assessment Product for marketing under this Agreement, and the remainder
shall be payable as further provided in this Section. That portion of the
Face Amount in excess of the Minimum Committed Amount shall be payable in

any other provision in this Agreement to the contrary, unless the parties

</TABLE>

For purposes hereof, each of the above dates (and any similar dates signifying
the end of a [****] payment period with respect to any other Assessment
Product) shall hereinafter be referred to as a "Calculation Date." Calculation
Dates for Assessment Products other than the ISRA product shall be each June 30
and December 31 following delivery of such products, unless otherwise agreed by
the parties.

                  B. On each Calculation Date, the aggregate of all revenues
accrued by Predictive from all Projects (based on work performed, and any
amounts against which credits are allowed pursuant to Section 3.7 C.), together
with the amount of any Up-Front Payments and Minimum Payments (as such term is
defined below) made prior to such date (collectively, "Aggregate Revenues")
shall be compared with the aggregate Minimum Committed Amounts for all Projects
payable through such Calculation Date. To the extent that such aggregate Minimum
Committed Amounts exceed the amount of the Aggregate Revenues, Cabletron shall
pay Predictive the difference (a "Minimum Payment") in accordance with Section
3.8.

                  C. All Up-Front Payments and Minimum Payments shall be fully
earned when paid and shall be non-refundable; however, Cabletron shall be
entitled to a credit against any consideration payable to Predictive based on
work performed by Predictive with respect to any Project, but shall not be
credited against any reimbursable expenses. To the extent that any such
non-refundable amounts exceed the amounts credited pursuant to the preceding
sentence, Cabletron shall be entitled to commission new work from Predictive
within Predictive's core competencies, either directly for Cabletron or for a
Cabletron customer, and to take a credit against such work. Any amounts due to
Predictive in excess of any such credit (including any amounts payable from that
portion of any Purchase Order in excess of the Minimum Committed Amount thereof)
shall be paid by Cabletron in accordance with Section 3.8 hereof.

                  D. Attached hereto as Schedule 3.7, for illustrative purposes
only, is an example of the computation of payments pursuant to this Section 3.7.

services in connection with all Projects hereunder and any additional amounts
and reimbursable expenses payable under this Agreement. All such invoices shall
be payable net [****] days (together with any applicable Minimum Payments

that upon mutual agreement of the parties such payments may be made by wire
transfer to an account designated by Predictive. [****].


         3.9 [****] Cabletron may within sixty (60) days after receiving such
notice elect to substitute the Pricing Algorithm (or its equivalent) for such
product under such agreement for the then-applicable Pricing Algorithm
hereunder, provided, in such event, that Cabletron shall be required to
assume in writing and to perform all materials terms governing consideration
and material other obligations, and satisfy any material conditions, to which
such third party is subject under its agreement with Predictive. Nothing in
this Section 3.9 shall be construed to modify the restrictions on the parties
contained in Section 5 of this Agreement.



4.       FOLLOW-ON PROJECTS

         4.1 It is anticipated that Follow-On Projects will either consist of
work as to which only one of the parties has the relevant service capability
("Non-Overlap Work") or work as to which both parties have the relevant service
capability ("Overlap Work"). Listed in Schedule 4.1 are the categories
constituting Overlap Work and Non-Overlap Work between the parties (the "Overlap
Schedule"). The Overlap Schedule shall be periodically updated by the parties to
reflect changes in their respective capabilities. In the event that a dispute
arises as to which party has the relevant capability (or as to whether a
particular Project constitutes Overlap Work or Non-Overlap Work), such issue
shall be resolved in accordance with Section 21.8.



         4.2 Non-Overlap work in connection with any Follow-On Project shall
be performed by the party having the relevant capability. [****] All
Non-Overlap Work, whether performed by Predictive or Cabletron [****] with
respect to Non-Overlap Work performed by Cabletron.

intervals as may be determined by the parties, the Oversight Committee shall
review all such Projects on a case-by-case basis, with a view towards
allocating such Projects so that their benefits, and the nature and character
of business so conducted, [****].



         4.4 Prior to undertaking any Follow-On Projects, the parties shall
mutually agree to, and attach hereto as Schedule 4.4, an Implementation Schedule
for Follow-On Projects generally.

         4.5 The parties shall cooperate to produce a standard agreement for
Follow-On Projects, but recognize that the Customer may require changes thereto.
Each of the parties agrees not to unreasonably withhold consent to such changes,
consistent with its generally applicable operational and risk management
policies.

Follow-On Projects to its Customers that have ordered Assessment Projects,
consistent with reasonable business practices and the Customers' interests.
Predictive shall conduct each Assessment Project, and each party shall conduct
each Follow-On Project performed by it, with a view to developing and/or
maintaining good business relations between the Customer and the
Cabletron/Predictive Strategic Partnership.

4A.      TEAMING PROJECTS

         The parties may mutually agree as t specific Cabletron customers as to
which it may be more advantageous to service through a Teaming Project than for
either party to service independently. Such potential customers shall be listed
on (or added to ) Schedule 4A hereto, to be mutually executed by the parties,
which Schedule shall also indicate the date each such potential customer was
added to the Schedule. Except to the extent otherwise provided in this
Agreement, Teaming Projects shall be treated as Follow-On Projects for all
purposes hereof, including but not limited to pricing and implementation.

5.       CERTAIN OPERATING RESTRICTIONS.

         5.1 A. Predictive acknowledges that Cabletron enjoys an advantageous
 relationship with its customers. Predictive further acknowledges that, by
 performing services for Cabletron under this Agreement, Predictive, and its
 employees and agents, may become privy to certain confidential information of
 Cabletron which if disclosed to or used by third parties, including Predictive
 and its employees and agents, would prejudice Cabletron's competitive advantage
 in the marketplace. Therefore, Predictive agrees that:

         (1)      Except as permitted under Section 5.6, and subject to the
                  remaining provisions of this Section 5.1, following a
                  commitment by a Customer for a Project that results in fees to
                  Predictive of at least [****], Predictive will not
                  independently, directly or indirectly, solicit such Customer
                  to perform services covered by this Agreement of substantially
                  similar thereto from the time of such commitment until the
                  expiration of [****] following the delivery of services
                  hereunder (including any Follow-On or Teaming Projects
                  subsequently performed for such Customer). Such period shall
                  be increased to [****] following delivery for any Project
                  which generates fees to Predictive of [****] or more. For
                  purposes of the foregoing provisions of this Section 5.1A, the
                  "Customer" shall be deemed to be the business unit as to which
                  the relevant Customer decision-maker exercises purchasing
                  authority (regardless of whether such business unit
                  comprises one or more locations), and shall not be construed
                  to preclude Predictive from offerings its services to other
                  business units within the same organization; PROVIDED,
                  HOWEVER, that Predictive shall promptly notify Cabletron of
                  any other business units of a Cabletron Customer with which it
                  has entered an agreement to sell such services. Nothing in
                  this Section 5.1A (1) shall be construed to prohibit
                  Predictive from participation in the efforts of a third party
                  to market a potential project for services which Predictive

                  other proceeding or the settlement of any such claim, as the
                  case may be. Contractor shall immediately notify LCI and
                  defend LCI and Affiliates against any such claims, actions, or
                  other proceedings, and shall conduct any settlement
                  negotiations, on behalf of LCI at Contractor's sole cost and
                  expense: provided that LCI may elect to participate in the
                  defense and any settlement negotiations through counsel of its
                  own choosing and at its own cost, and provided that LCI shall
                  have final approval of any settlement requiring payment from
                  LCI or reducing LCI's rights to use any property which forms
                  the subject matter of the claim, action or proceeding. The
                  foregoing provisions of this Article 18 (a)(ii) and the
                  provisions of Article 18(a)(iii) shall not apply to any Third
                  Party IP.

         (iii)    Should the Work or any portion of the Work provided by
                  Contractor become, or in Contractor's opinion is likely to
                  become, the subject of a claim or infringement, or should
                  LCI's use of the Work be finally enjoined, Contractor shall,
                  at its expense:

                           (A) Procure for LCI the right to continue using,

         non-infringing provided that such replacement or modified Work
         continues to comply substantially with all applicable specifications or
         other requirements under this Agreement; or

                           (C) If neither of the foregoing can be suitably
         accomplished, reimburse LCI for the Work by refunding to LCI the price
         paid by LCI for the Work.

                                    (i) In the course of performing its services
         under this agreement, Contractor may devise, create or develop computer

         be defined, other software, hardware, material, devices or inventions
         for other, specific purposes which would be defined in one or more
         Statements of Work in addition to those contemplated in Article 2(a)
         ("Additional Deliverables"). "Deliverables" collectively refers to the
         combination of System Deliverables and Additional Deliverables, if any.

                                    (ii) Contractor owns and shall retain all
         right, title and interest in and to all of the System Deliverables and
         all of its architecture, programming and engineering ideas, techniques,
         methods or know-how, as well as all patents, copyrights, trademarks,

         license granted in Article 18 (b)(iii), it shall make no claim to the
         contrary by virtue of this Agreement or otherwise.

                                    (iii) Contractor grants to LCI an
         irrevocable, perpetual, non-exclusive, fully-paid license to use all

         Software, Documentation reports, programs, source code, manuals, flow
         charts, tapes, card decks, listings and any other programming materials
         and all inventions, whether or not patentable) forming any portion of
         any Additional Deliverables created, composed, made or conceived by
         Contractor or Contractor Personnel during the performance of Work. The
         Parties agree that, except as may be otherwise provided in the related
         Statement of Work or amendment to this Agreement, each Additional
         Deliverable is a work made for hire, that all portions of any
         additional Deliverable, including all copyrights, any extension or
         renewals, and all related work, shall be the exclusive property of LCI,
         and that LCI shall have the right, at its own expense, to obtain and to

         sole and continuing right (without any payments or liabilities to any
         person) to use the Additional Deliverables and to publish, perform,
         reproduce and distribute throughout the world any or all portions of
         such Additional Deliverables, either as a complete unit or in segments,
         in any way LCI sees fit and for any purpose whatsoever. Contractor
         shall insert a proper statutory copyright notice at an appropriate
         location on copyrightable material, and on all portions and on all
         related items which may be subject to copyright protection, which
         copyright notice shall specify LCI as the sole copyright owner.
         Contractor further agrees to give LCI or any person designated by LCI,
         at LCI's expense, all such information and to execute all such
         additional documents including, without limitation, patent
         applications, as may be reasonably required to

         perfect the rights referred to herein. In the event Contractor or third
         party is deemed to be author for copyright purposes of any such
         materials and Additional Deliverables under this Agreement, Contractor
         agrees to assign or cause such third party to assign and execute and
         have its Contractor Personnel execute any documents (including patent
         applications and assignments) reasonably requested by LCI, at LCI's
         expense, to provide LCI the right to won, use and protect the
         Additional Deliverable under this subparagraph.

(i)               Notwithstanding the foregoing provisions of this Article 14,
         the Parties acknowledge that in some cases the Work, or as portion
         thereof, may use, incorporate or be dependent upon patents, copyrights,
         trade secrets and/or other intellectual property that is either owned
         by Contractor, the ownership of which by Contractor pre-dates the Task
         Order for the affected Work (the "Pre-Existing Contractor IP") or is
         owned by third parties ("Third Party IP"). Contractor shall disclose to
         LCI prior to entering into any Task Order for Work hereunder, but in
         any case in advance of commencing any affected Work hereunder, the
         extent to which such Work, or any portion thereof, will use,
         incorporate or be dependent upon any such Pre-Existing Contractor IP or
         Third Party IP, and whether or not so identified to LCI.

         (A)      Contractor hereby grants to LCI a non-exclusive, fully-paid,
                  irrevocable and perpetual license to use such Pre-Existing
                  Contractor IP solely in connection with the installation use
                  and maintenance of the NOC and otherwise on the terms and
                  conditions set forth in Article 18(b)(iii) above. Contractor
                  represents and warrants that Contractor has sufficient right,
                  title and interest to grant the foregoing license in the
                  Pre-Existing Contractor IP to LCI.

         (B)      Contractor shall further use its best efforts to obtain for
                  LCI license rights to any such Third Party IP as are necessary
                  or appropriate to LCI's ownership and use of the Work.

         (C)      Contractor agrees to give LCI or any person designated by LCI,
                  at Contractor's expense, all such information and to execute
                  all such additional documents as may be reasonably required to
                  perfect LCI's rights to the license granted pursuant to
                  subsection (c)(i)(A) above or any license granted pursuant to
                  subsection (c)(i)(A) above.

         further recognized that Contractor will develop material and
         information which LCI will wish to hold and to be held by Contractor as
         confidential and proprietary information of LCI. Accordingly,
         Contractor agrees to the following with respect to Confidential

Agreement;

         (ii) Not to make copies of any Confidential Information or any part

Contractor;

         (ii) It enters into the public domain through no fault of Contractor
subsequent to the time of LCI's communication to Contractor;

         (iii) It was in Contractor's possession of any obligation of confidence

         reasonably possible Contractor agrees to give LCI prompt notice if
         Contractor becomes aware either [****]



(f)      Contractor will enter into non-disclosure agreements with its
         Contractor Personnel sufficient in form and substance to ensure
         compliance by such Contractor Personnel with the provisions of this

         at all times for compliance of such Contractor Personnel with this
         Article for so long as they are in the employment of Contractor and a
         period of six (6) months thereafter.

(g)      As to any Confidential Information either disclosed by LCI to
         Contractor, or developed by Contractor, prior to the effective date of
         this Agreement and in connection with the Work to be performed
         hereunder, Contractor agrees that: (i) where the parties entered into
         an applicable separate Nondisclosure Agreement prior to such effective
         date, then



****  Represents material which has been redacted and filed separately with
the Commission pursuant to a request for confidential treatment pursuant to

         such Nondisclosure Agreement shall continue to apply to such
         information for the period prior to the effective date of this
         Agreement and after the effective date the provisions of this Agreement
         shall apply, and (ii) where an applicable separate Nondisclosure
         Agreement was not entered into between the parties, all such disclosed
         and developed information shall be deemed to be LCI Confidential
         Information subject to the terms and conditions of this Agreement. In
         any event, any such information developed by Contractor prior to the
         effective date of this Agreement shall nonetheless be deemed to be part
         of the Work subject to the terms and conditions of this Agreement.

(h)      Contractor acknowledges that the Confidential Information under this
         Agreement constitutes unique, valuable and special trade secret and
         business information of LCI, and that disclosure may cause irreparable
         injury to LCI. Accordingly, Contractor acknowledges and agrees that the
         remedy at law for any breach or threatened breach of the covenants
         contained in this Agreement may be inadequate, and in recognition,
         agrees that LCI shall, in addition, be entitled to injunctive relief
         without bond including reasonable attorneys' fees and other court costs
         and expenses.

ARTICLE 21 - FORCE MAJEURE

         floods, explosions, the elements, epidemics, quarantine, restrictions,
         strikes, lock-outs, plant shutdown. Third Party defaults (provided
         Contractor has complied with Article 16(b)) or delays in
         transportation. In the event of an excusable delay as defined in the
         preceding sentence, then Contractor, upon giving prompt written notice
         to LCI, shall be excused from such performance on a day-to-day basis to
         the extent of such prevention, restriction, or interference, provided
         that Contractor shall use its best efforts to avoid or remove such
         causes of nonperformance and both parties shall proceed to perform with
         dispatch whenever such causes are removed to cease to exist.

(b)      It any performance date under this Agreement is postponed or extended
         pursuant to this Section for longer than 60 calendar days, LCI may, at
         its option, by written notice given during the postponement or
         extension, terminate Contractor's right to render further performance
         after the effective date of termination without liability for that
         termination.

ARTICLE 22 - PUBLICITY

Both parties agree that no news releases, public announcements or advertising
materials, or confirmation of same, concerning any part of this Agreement or any
of its performance, or use of the other Party's name, logo or service marks in
advertising or sales materials shall be made without the prior written approval
of the other Party. Such requests shall be in writing and addressed in
accordance with the article entitled "Notices."

         including legal fees, which LCI may incur as a result of such changes
         in status.

(b)      Personnel supplied by Contractor will be deemed employees of Contractor
         and will not for any purposes be considered employees or agents of LCI.
         Contractor shall be solely responsible for their supervision, direction
         and control, as well as payment of salary (including withholding of
         income taxes and social security), worker's compensation, disability
         benefits and the like.

(c)      Nothing contained in this Agreement shall be deemed or construed as
         creating a joint venture or partnership between Contractor and LCI.
         Neither Party is by virtue of this Agreement authorized as an agent,
         employee or legal representative of the other. Except as specifically
         set forth, neither Party shall have power to control the activities and
         operations of the other and their status is, and at all times will
         continue to be, that of independent contractors. Neither Party shall
         have any power or authority to bind or commit the other.

         professional standards in the industry, shall be free of defects in
         materials and design, and that the Deliverables shall comply with the
         specifications set forth in the Statements of Work for six (6) months

         breach of the foregoing.

(d)      Contractor shall warrant, without limitation as to any time period,

3.1.     Subcontractor acknowledges that, in connection with this Agreement and
         its relationship with Cisco, it may obtain information relating to
         Cisco or Cisco's hardware, software, services or products which is of a
         confidential and proprietary nature ("Confidential Information"). Such
         Confidential Information may include, but is not limited to, trade
         secrets, know-how, inventions, techniques, processes, programs,
         schematics, software source documents, data, customer lists, financial
         information, and sales and marketing plans or information which
         Subcontractor knows or has reason to know is confidential, -
         proprietary or trade secret information of Cisco, its affiliates and
         suppliers. Subcontractor shall at all times, both during the term of
         this Agreement and for a period of at least three (3) years after its
         expiration or termination or the completion of the last SOW, whichever
         is later, keep in trust and confidence all such Confidential
         Information, and shall not use such Confidential Information other than
         as expressly authorized by Cisco under this Agreement, nor shall
         Subcontractor disclose any such Confidential Information to third
         parties without Cisco's written consent. Subcontractor further agrees
         to immediately return to Cisco all Confidential Information (including
         copies thereof) in





                                       4
<PAGE>

         Subcontractor's possession, custody, or control upon expiration or
         termination of this Agreement at any time and for any reason or the
         completion of the last SOW, whichever is later. The obligations of
         confidentiality shall not apply to information which (a) has entered
         the public domain except where such entry is the result of
         Subcontractor's breach of this Agreement or other applicable
         confidentiality agreement; (b) prior to disclosure hereunder was
         already rightfully in Subcontractor's possession under no obligation of
         confidentiality; (c) subsequent to disclosure hereunder is obtained by
         Subcontractor on a nonconfidential basis from a third party who has the
         right to disclose such information to the Subcontractor; or (d) is
         independently developed without restriction on disclosure and without
         the use of any Confidential Information. Nothing contained in this
         Section 3.1 shall prohibit Subcontractor from making disclosure of
         Confidential Information to the extent (but only to the extent)
         required by court order, provided that Subcontractor shall use its best
         efforts to give Cisco at the earliest practicable time prior notice as
         to the nature of the required disclosure or request for such
         disclosure, whichever is earlier, so as to afford Cisco the maximum
         possible opportunity to challenge the need for such disclosure; and
         provided further that Subcontractor shall cooperate with Disco in
         resisting such disclosure.

         For purposes of this Agreement, Confidential Information of Cisco is
         deemed to include (i) any information provided to Subcontractor which
         Cisco is required to keep confidential pursuant to the terms of the PSA
         and (ii) any Confidential Information of a Customer which Cisco or the
         Customer may provide to Subcontractor in order to propose or perform
         work in accordance with any SOW hereunder (collectively (i) and (ii)
         are referred to herein as "Customer Confidential Information").
         Subcontractor shall comply with the confidentiality provisions of the
         PSA related to all Customer Confidential Information.

3.2.     Neither party shall disclose, advertise, or publish the terms and
         conditions of this Agreement or any SOW without the prior written
         consent of the other party. Any press release or publication regarding
         this Agreement or any SOW is subject to prior review and written
         approval of the parties. Subcontractor shall not disclose the existence
         of any relationship with Cisco without Cisco's prior written approval.

3.3.     Notwithstanding anything in this Agreement to the contrary, neither
         party shall use the other party's name, logo, trademarks, service
         marks, or other proprietary symbols or designations (the "Marks")
         without the prior consent of the other party. Subcontractor shall have
         no claim or right in Cisco's Marks, including but not limited to
         trademarks, service marks, or trade names owned, used or claimed now or
         in the future by Cisco. Subcontractor shall not make any claim to
         Cisco's Marks or lodge any filings with respect to Cisco's Marks or
         marks confusingly similar to Cisco's Marks, whether on behalf of Cisco
         or in its own name or interest, without the prior written consent of
         Cisco.

4.       SUBCONTRACTOR'S REPRESENTATIONS, WARRANTIES, AND COVENANTS.

         Subcontractor represents, warrants and covenants as follows:

                  the Subcontractor Work Product and Services have been accepted
                  pursuant to Article 8 of this Agreement or such later time as
                  Cisco may reasonably require (collectively, (i) and (ii) of

                  expiration, termination, non-renewal, denial or revocation of
                  any Authorization;

         4.2.3.   shall not act in any fashion or take any action which will
                  render Cisco liable for a violation of the U.S. Foreign

                  prohibition against the offering, giving or promising to offer
                  or give, directly or indirectly, money or anything of value to

         Subcontractor uses under this Agreement or any SOW ("Cisco Owned
         IP"). Subject to Sections 6.2 and 6.3, Subcontractor acknowledges
         and agrees that Cisco or its assigns shall own, and Subcontractor
         hereby assigns to Cisco, all intellectual property rights and other
         proprietary rights in and to the Services and the Subcontractor Work
         Product, and any other materials and information Subcontractor is
         required to deliver to Cisco as part of this Agreement and any SOWs
         issued hereunder, and any Results created as a result of performance
         of this Agreement and any SOW hereunder (the "Developed IP"; the
         Developed IP and the Cisco Owned IP are collectively referred to as

         work rights, copyrights, and such other proprietary rights
         protections with respect to the intellectual property rights
         described in this Section 6.1. Subcontractor shall execute such
         documents, render such assistance, and take such other actions as
         Cisco may reasonably request, at Cisco's expense, to apply for,
         register, perfect, confirm and protect Cisco's rights in any
         intellectual property described in this Section 6.1. Without
         limiting the foregoing, Cisco shall have the exclusive right to

         intellectual property rights granted to it under this Section 6.1.



6.2.     OWNERSHIP BY SUBCONTRACTOR. Except as otherwise set forth below,
         Subcontractor shall own or retain its rights in all right, title and
         interest in Subcontractor intellectual property which is used in the
         performance of this Agreement or any SOW hereunder that is wholly
         developed and owned by or licensed to Subcontractor prior to the
         Effective Date of this Agreement. Cisco grants to Subcontractor a
         perpetual, irrevocable, worldwide, fully paid up, royalty-free,
         non-exclusive, personal and nontransferable license to use
         intellectual property which Subcontractor develops in the course of
         performance of the Services and or otherwise develops after the
         Effective Date which is discernible by, or disclosed or delivered
         to, either Cisco or Customer. Notwithstanding the foregoing, Cisco
         shall own all Deliverables pursuant to the provisions of Section 6.1
         and the license rights set forth in this Section 6.2 shall not apply
         to any such Deliverable (but such license shall apply to the
         intellectual property therein).


6.3.     SUBCONTRACTOR GRANT OF LICENSE. If any intellectual property used or
         developed hereunder or any Services, Subcontractor Work Product or
         Results are based on, or incorporate or are improvements or
         derivatives of, or cannot reasonably be made, used, reproduced and
         distributed without using or violating intellectual property rights,
         the rights of which are not assigned or otherwise obtained by Cisco
         hereunder, Subcontractor hereby grants to Cisco a perpetual,
         irrevocable, worldwide, fully paid up, royalty-free, non-exclusive,
         right and license, including the right to sublicense and to
         authorize the granting of sublicenses, to exploit and exercise all

         waives any and all moral rights, including without limitation any
         right to identification of authorship or limitation on subsequent
         modification that Subcontractor (or its employees, agents,
         subcontractors or consultants) has or may have in the Services,
         Subcontractor Work Product or Results, and in any other intellectual
         property that is or becomes the property of Cisco under this Section.


6.5.     CISCO AS ATTORNEY IN FACT. Subcontractor agrees that if Cisco is
         unable because of Subcontractor's unavailability, dissolution or
         incapacity, or for any other reason, to secure Subcontractor's
         signature to apply for or pursue any application for any United
         States or foreign patents or mask work or copyright registrations
         covering the inventions assigned to Cisco above; then Subcontractor
         hereby irrevocably designates and appoints Cisco and its duly
         authorized officers and agents as Subcontractor's agent and attorney
         in fact, to act for and in Subcontractor's behalf and stead to
         execute and file any such applications and to do all other lawfully
         permitted acts to further the prosecution and issuance of patents,
         copyright and mask work registrations thereon with the same legal
         force and effect as if executed by Subcontractor.

         and documents relating thereto which are in Subcontractor's possession
         and notifying Cisco of the termination. This license will terminate
         immediately without notice from Cisco if Subcontractor fails to comply
         with any provision of this license.

7.4.     If any portion of this license section is found to be void or
         unenforceable, the remaining provisions of this license shall remain in
         full force and effect. This license constitutes the entire license

         completion criteria specified in the Statement of Work to the
         reasonable satisfaction of Cisco, as evidenced by issuance of written
         confirmation of completion and acceptance by Cisco. Final acceptance of

10.      INDEPENDENT CONTRACTOR

         Cisco and Subcontractor are independent contractors and have no power
         or authority to bind the other or to create any obligation or
         responsibility on behalf of the other. Under no circumstances shall any
         employee of one party be deemed to be the employee of the other for any
         purpose. Nothing herein shall be construed as implying a joint venture,
         agency, employer-employee or partnership relationship between the
         parties hereto. Subcontractor is solely responsible for all of its own
         taxes, withholdings, and other similar statutory obligations related to
         this Agreement and any SOW.

11.      RELATIONSHIP TO THE PSA.

         Selection of subcontractors to perform the work required under a
         particular Customer PSA shall be in the sole discretion of Cisco, and
         is, if required by the PSA, subject to Customer approval. Subcontractor
         agrees that all its personnel who, pursuant to this Agreement, will be
         on Cisco's or a Customer's premises shall have appropriate
         authorization issued by Cisco and/or Customer prior to being accorded
         access to such premises. Denial of access because of failure to comply
         with either Cisco's or Customer's security procedures shall not be the
         basis of a claim for breach, nor substantiate any other claim
         whatsoever by Subcontractor.

12.      CHANGES TO A SOW.

         Cisco may at any time by written request make changes to a SOW,
         provided such changes are within the general scope of the SOW, and
         Subcontractor shall proceed without delay to evaluate requested changes
         and notify Cisco promptly (but in all cases within twenty-four (24)
         hours after receiving such request) of any objections to the requested
         changes. Should any change to an SOW directly result in a change to the
         time, place or cost of performance of the SOW, Subcontractor shall,
         within the earlier of the time specified in such request or fifteen
         (15) days of being directed to implement the change, notify Cisco that
         there will be an impact to the SOW cost or schedule and describe such
         impact. In the event the Parties reasonably determine such a change
         increases or decreases the cost of, or the time required for,
         performance of the Services or preparation of the Subcontractor Work
         Product under any SOW, the Parties shall agree upon an equitable
         adjustment to the SOW, including possible adjustment of prices or
         delivery schedules. For changes requested by Cisco at Customer's
         request or direction, such equitable adjustment shall be subject to
         Customer's approval and funding.

13.      TERM.


         This Agreement will commence on the Effective Date and will continue in
         effect for a period of four (4) years or for the period of any
         incomplete SOW in existence on the expiration date, whichever is later,
         unless amended to establish a later expiration date by





                                       12
<PAGE>

         a written agreement signed by both parties, or until terminated as
         provided in this Agreement.

14.      TERMINATION.


14.1.    Cisco may terminate this Agreement or any individual SOW at any
         time, with or without cause, by giving ten (10) days written notice
         to Subcontractor. In the event of a termination due to breach by
         Subcontractor of this Agreement or any SOW, Cisco may, in its sole
         discretion, offer Subcontractor the opportunity to cure within the
         ten (10) day notice period. In the event of a termination or failure
         to cure under this subsection, as of the tenth day after receipt of
         notice of termination, Subcontractor shall immediately cease work on
         the terminated matter(s), performing only efforts reasonably
         necessary to wind down and preserve work that has been performed or
         as specified in Section 14.4. In the event of a termination of this
         Agreement, or any SOW, for any reason, Subcontractor shall be
         obligated to deliver, and Cisco will be obligated to pay
         Subcontractor for, only Services and Subcontractor Work Product
         actually performed or prepared by Subcontractor prior to the date of
         termination, and delivered to and accepted by Cisco (such acceptance
         by Cisco to not be unreasonably withheld) and by Customer within a
         reasonable time after the effective date of termination, consistent
         with the payment terms in the SOW. Subcontractor shall also take all
         actions required to protect and preserve new property in the
         possession of Subcontractor in which Cisco or Customer has an
         interest. Cisco may, upon notice to Subcontractor, deduct from the
         amounts otherwise payable by Cisco to Subcontractor any undisputed
         amounts payable by Subcontractor to Cisco.



14.2.    Subcontractor may terminate this Agreement and/or any individual SOW
         if Cisco breaches a material provision of this Agreement or any SOW
         and fails to cure such breach within thirty (30) days of receipt of
         written notice of the breach from Subcontractor.


14.3.    Notwithstanding the foregoing, this Agreement and/or any SOW hereunder
         may be terminated immediately by Cisco in the event of (i)
         Subcontractor's breach of Subsection 2.5 (licenses and permits),
         Section 3 (Confidentiality), Section 4 (Subcontractor's
         Representations, Warranties and Covenants), Section 6 (Ownership and
         License), Section 7 (Software License), or Subsection 19.10 (Export Law
         Control), (ii) in the event of a sale of all or substantially all of
         Subcontractor's assets, or transfer of a controlling interest in
         Subcontractor to an unaffiliated third party or (iii) expiration or
         termination of the PSA for any reason.

14.4.    Notwithstanding the foregoing, upon termination of this Agreement for
         any reason, Cisco reserves the right to determine whether to require
         Subcontractor to complete any SOWs previously executed by Cisco and
         Subcontractor. If completion is required by Cisco, Subcontractor shall
         perform the relevant SOW(s) in conformance with their respective terms
         and conditions, and this Agreement, including this termination section,
         will continue to apply to that performance.




                                       13
<PAGE>

14.5.    Subcontractor shall, if requested by Cisco, take all reasonable steps
         to achieve an orderly transition upon termination and shall, if
         requested by Cisco, provide reasonable training for Cisco or third
         party personnel and other support and assistance to ensure continuity
         in the performance of the obligations set forth in the PSA. If the
         efforts required are more than nominal transfers of residual materials
         and information, Cisco will pay Subcontractor a reasonable fee for such
         training and other services as may be mutually agreed by the parties;
         provided, however that Subcontractor shall not refuse to provide such
         training and other services prior to agreement by the parties with
         respect to such fees.

14.6.    Subcontractor and Cisco shall continue performing its obligations under
         this Agreement while any dispute with Cisco is being resolved unless
         and until this Agreement and all SOWs expire or terminate.

14.7.    The rights and remedies of each party provided in this Section shall
         not be exclusive and are in addition to other rights and remedies
         provided at law, in equity or otherwise under this Agreement.

15.      INDEMNIFICATION.

15.1.    Subcontractor shall defend, indemnify and hold harmless Cisco, its
         corporate affiliates and their officers, directors, employees and
         agents and their successors and assigns, against and from any and all
         claims, judgments, liabilities, losses, injuries, penalties, fines and
         damages of every nature (including, without limitation, incidental
         costs and expenses, reasonable attorney's fees, reasonable costs of
         investigation and litigation, interest and penalties) to the extent
         caused by the acts or failure to act of Subcontractor, its officers,
         directors, employees, agents, consultants, subcontractors or vendors,
         directly or indirectly arising out of or in conjunction with
         Subcontractor's performance of this Agreement or related SOWs,
         including without limitation failing to comply with any applicable law
         or regulation or failing to obtain or maintain the validity of any
         state, local or federal permit, license, or approval required for
         performance of either party's obligations hereunder.

15.2.    This indemnity protection includes any claims of infringement of
         intellectual property rights and claims of use of confidential or
         proprietary information of third parties, as provided in Section 5
         hereof. In such cases, as for other indemnifiable actions,
         Subcontractor will pay the costs of defense and settlement and any
         costs and damages finally awarded by a court, arbitrator, mediator, or
         the other decision making authority of competent jurisdiction against
         Cisco. If such a claim is made or appears likely to be made,
         Subcontractor may procure the right for Cisco to continue using the
         allegedly infringing item, may modify the item or may replace it. If
         use of the alleged infringing item by Cisco or a Customer is enjoined,
         and Subcontractor determines that none of these alternatives is
         reasonably available, Subcontractor will take back the infringing item
         and refund its depreciated value, and replace the item or re-perform
         the affected work with non-infringing items. The rights and remedies of
         Cisco provided in this Section shall not be Cisco's exclusive remedy
         and are in addition to all ocher rights and remedies of Cisco provided
         at law, in equity or otherwise.


                                       14

         Subcontractor shall not settle any claims under this Section 15 without
         Cisco's prior written consent. Cisco shall reasonably cooperate with
         Subcontractor, at Subcontractor's expense, in the defense of any claims
         under this Section 15.

16.      CONSEQUENTIAL DAMAGES WAIVER

         EXCEPT FOR LIABILITY ARISING OUT OF OR IN CONNECTION WITH
         SUBCONTRACTOR'S BREACH OF SECTION 3 (CONFIDENTIALITY), SECTION 6
         (OWNERSHIP AND LICENSE) ) OR SECTION 7 (SOFTWARE LICENSE) OR SECTION
         8.10 (EXPORT LAW CONTROL) OR ANY OTHER BREACH OF CISCO'S PROPRIETARY
         RIGHTS UNDER THIS AGREEMENT, IN NO EVENT SHALL EITHER PARTY OR ITS
         SUPPLIERS BE LIABLE TO THE Old PARTY FOR ANY PUNITIVE, SPECIAL,
         INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOST PROFITS OR LOST DATA, OR ANY
         OTHER INDIRECT DAMAGES AS A RESULT OF A BREACH OF THIS AGREEMENT EVEN
         IF SUCH PARTY OR ITS SUPPLIERS HAVE BEEN INFORMED OF THE POSSIBILITY
         THEREOF. Payments based on the indemnification obligations of
         Subcontractor shall be considered direct damages and are not subject to
         the foregoing waiver of consequential damages without regard to the
         nature of the third party claim giving rise to the indemnification
         obligation.

17.      INSURANCE.

17.1.    Subcontractor shall at all times during the term of this Agreement and

         those insurance policies and minimum limits of coverage as designated
         below or such additional policies or higher amount as required (and
         subject to any additional terms) as are required by the PSA, and any
         other insurance required by an SOW or by law in any state where
         Subcontractor or its subcontractor(s) (regardless of tier) provides
         Services under this Agreement, in insurance companies with an A.M.
         Best's Insurance Rating of A:VIII or better or otherwise acceptable to

                  Subcontractor's employees under the US Longshoremen's and
                  Harbor Workers' Compensation Act, the Jones Act or under laws,
                  regulations or statutes applicable to maritime employees,
                  coverage shall be included for such injuries or claims.

                  policy of Commercial General Liability or Public Liability

                                       16

                  Subcontractor Work Product by Cisco. Subcontractor shall
                  furnish Certificates of Insurance annually to Cisco at the
                  beginning of each of these subsequent three years as evidence
                  of this required insurance.

         17.1.7.  Cisco, its officers, directors, employees and agents shall be
                  named as Additional Insureds for General Liability and
                  Excess/Umbrella liability policies above. The policy(s) shall
                  be endorsed to stipulate that Subcontractor's insurance shall
                  be primary insurance and that any other insurance maintained
                  by Cisco shall be excess only and non-contributing.

         17.1.8.  Certificates of Insurance shall be furnished by Subcontractor
                  to Cisco before work on any Services or Subcontractor Work
                  Product are commenced hereunder by Subcontractor and thirty
                  (30) days prior to policy renewal. The Certificates of
                  Insurance shall provide that there will be no cancellation or
                  non-renewal of coverage without thirty (30) days prior written
                  notice to Cisco. Copies of the endorsements required hereunder
                  shall be furnished with the certificates. If reasonably
                  requested by Cisco, a certified copy of the actual policy(s)
                  with appropriate endorsement(s) shall be provided to Cisco.

         17.1.9.  If Subcontractor does not comply with the insurance
                  requirements of this Section, Cisco may, at its option,
                  provide insurance coverage to protect Cisco and Subcontractor
                  and charge Subcontractor for the cost of that insurance. The
                  required insurance shall be subject to the approval of Cisco,
                  but any acceptance of insurance certificates by Cisco shall
                  not limit or relieve Subcontractor of the duties and
                  responsibilities assumed by it under this Agreement.

         17.1.10. Except where prohibited by law, Subcontractor does hereby and
                  its insurers and its subcontractor(s), consultants, suppliers,
                  and agents (regardless of tier) and their respective insurers
                  do hereby, waive all rights of recovery or subrogation against
                  Cisco, its affiliates and their respective officers,
                  directors, employee, agents, and insurers. Subcontractor shall
                  cause its subcontractor(s), consultants, suppliers and agents
                  (regardless of tier) and their respective insurers to
                  acknowledge and agree to such waiver and shall provide Cisco
                  with a copy of such waiver.

         17.1.11. Subcontractor shall obtain insurance or shall reimburse Cisco
                  or Customer, as appropriate, for loss or damage to any
                  Cisco-owned or Customer-owned property in the care, custody,
                  or control of Subcontractor, for all losses including, but not
                  limited to theft, loss, misappropriation or destruction caused
                  by Subcontractor, its employees, agents, members or
                  consultants whether intentional or through negligence.

         17.1.12. In the event Subcontractor utilizes the services of
                  subcontractors of any type to perform the Services
                  contemplated hereunder, Subcontractor shall require from or
                  provide for all subcontractors the same minimum insurance


                                       17
<PAGE>

                  requirements detailed above. Cisco reserves the right to
                  request copies of subcontractor certificates and/or certified
                  copies of insurance policies from Subcontractor when deemed
                  necessary.

18.      INJUNCTIVE RELIEF.

         The parties agree unauthorized use of Confidential Information,
         Subcontractor Work Product, or any information contained therein could
         irreparably diminish the value to Cisco of its trade secrets or
         proprietary information such that Cisco will have no adequate remedy in
         damages. Therefore, if Subcontractor breaches any of its
         confidentiality obligations hereunder, Cisco shall be entitled to
         equitable relief to protect its interests therein, including but not
         limited to injunctive relief, as well as monetary damages.

         Subcontractor agrees that such records will be available for audit by

         Convention on Contracts for the International Sale of Goods.


19.4.    NO WAIVER. No waiver of rights under this Agreement or any SOW
         hereunder by either party shall constitute a subsequent waiver of this

19.5.    ASSIGNMENT. Neither this Agreement nor any rights or obligations under
         this Agreement (nor any SOW hereunder), other than monies due or to
         become due, shall be assigned or otherwise transferred by Subcontractor
         (by operation of law or otherwise) without the prior written consent of
         Cisco. Cisco shall have the right to assign all or part of this
         Agreement without Subcontractor's approval. This Agreement and any SOW
         shall bind and inure to the benefit of the successors and permitted
         assigns of the parties.

         thereunder becomes or is declared to be illegal by any court of
         competent jurisdiction or other governmental body, such term(s) shall
         be null and void and shall be deemed deleted from this Agreement or the
         SOW. All remaining terms of this Agreement or the SOW shall remain in
         full force and effect. Notwithstanding the foregoing, if this paragraph
         becomes applicable and, as a result, the value of this Agreement or any
         SOW is substantially impaired for either party, then the affected party
         may terminate this Agreement or the SOW by written notice to the other.

19.7.    ATTORNEYS' FEES. In any suit or proceeding between the parties redating
         to this Agreement or any SOW hereunder, the prevailing party will have
         the right to recover from the other its costs and reasonable fees and
         expenses of attorneys, accountants, and other professionals incurred in
         connection with the suit or proceeding, including costs, fees and
         expenses upon appeal, separately from and in addition to any other
         amount included in any judgment in its favor issued by a court or other
         tribunal or decision maker of competent jurisdiction. This provision is
         intended to be severable from the other provisions of this Agreement,
         and shall survive and not be merged into any such judgment.

19.10.   EXPORT LAW CONTROL

         19.10.1. Subcontractor hereby acknowledges that the Services,
                  Subcontractor Work Product, Results, Cisco products and
                  technology or direct products thereof (hereafter referred to

                  export controls under the laws and regulations of the United
                  States (U.S.). Subcontractor shall comply with such laws and
                  regulations and agrees not to export, re-export or transfer
                  Products and Technology without first obtaining all required
                  U.S. government authorizations or licenses. Cisco and
                  Subcontractor each agree to provide the other such information
                  and assistance as may reasonably be required by the other in
                  connection with securing such authorizations or licenses, and
                  to take timely action to obtain all required support
                  documents.

         19.10.2. Subcontractor hereby certifies that none of the Products and
                  Technology supplied by Cisco or used or created by
                  Subcontractor under this Agreement will be exported,
                  re-exported, or otherwise transferred by Subcontractor:

                  (i)      to a U.S. embargoed or highly restricted destination,
                           (15 United States Code of Federal Regulations ("CFR")
                           Part 746)

                  (ii)     for use by or for any military end-user, or in any
                           military end-use located in or operating under the
                           authority of any country identified in Country Group

                           for, any entity that is engaged in the design,
                           development, production, stockpile or use of nuclear,
                           biological or chemical weapons or missiles, (15 CFR
                           Part 744)

                  (iv)     to parties on any of the U.S. Government's lists of
                           denied persons, (15 CFR Part 764)

         without first obtaining all required U.S. Government authorizations or
         licenses.

         Subcontractor's obligation under this Section 19 shall survive the
