                               PROSPECTUS SUMMARY

   This summary may not contain all of the information that is important to
you. You should carefully read the entire prospectus, including the financial
statements and related notes, before investing in our common stock. Unless
otherwise indicated, all information in this prospectus:
  .  assumes that the underwriters will not exercise their over-allotment
     option;
  .  reflects a four-for-three stock split effective as of December 1, 1999;

  .  assumes the issuance during the first quarter of 2000 of an aggregate of
     20,863 shares of class A preferred stock to existing holders of class A
     preferred stock for $18,658,000 pursuant to a Securities Purchase
     Agreement, dated March 23, 1999;

  .  reflects the exchange upon the closing of this offering of all
     outstanding shares of class A preferred stock, including related accrued
     and unpaid dividends, for shares of common stock at an exchange rate
     based on an assumed initial public offering price of $12.00 per share,
     the mid-point of the range on the cover of this prospectus; and

  .  assumes the conversion upon the closing of this offering of a $2.0
     million promissory note issued to Renaissance Worldwide, Inc. into
     208,333 shares of common stock, which is based on a conversion rate
     equal to 80% of the assumed initial public offering price.

                                [LOGO OF ZEFER]

   ZEFER Corp. was founded for the purpose of providing consulting, software
application development and strategy implementation services to dot-com and
traditional companies to enable them to effectively use the Internet in their
businesses. A key aspect of our service offering is that we involve business
strategy consultants throughout our engagements in order to continually improve
the client solution in light of evolving markets and technologies. We refer to
this as a "strategy-led" approach.

   We help our clients identify business objectives and create and prioritize a
portfolio of initiatives for using the Internet in their businesses. We design
these initiatives to offer a variety of ways to maximize competitiveness in the
new economic environment that has resulted from the widespread acceptance of
the Internet. After creating an initial Internet strategy, we architect and
build scalable, flexible solutions that can be adapted over time to our
clients' evolving needs.

   Our strategy-led approach includes:
  .  analyzing the client's industry, business model and goals;
  .  developing a portfolio of Internet initiatives in the context of an
     overall business strategy; and
  .  developing and launching various Internet initiatives in a sequence that
     is designed to maximize business value over the long term.

   We deliver our services through teams of consultants with backgrounds in
business strategy, experience design, technology and program management.
Because these teams include consultants with different skills who work closely
together throughout a client engagement, we refer to them as being "integrated"
and "multidisciplinary." Our integrated, multidisciplinary approach allows us
to deliver high quality Internet initiatives without the time delays and
increased costs associated with handing off a project from one team to another
or among multiple service providers. Our commitment to research and innovation
allows us to provide our clients with Internet professional services that are
at the forefront of Internet technologies and experience design. Our
consultants are trained in the latest practices and technologies in their
disciplines, and many of them are experts in their fields.

                                       1
<PAGE>


   Our delivery model is based upon a proprietary methodology that we call
ENABLE. This methodology consists of four phases: ENvision, Architect, Build
and Launch, and Evolve. Our ENABLE methodology is designed to ensure that we:

  .  involve all of our competencies in each phase of our engagements;

  .  take advantage of the standards, benchmarks and approaches we have
     developed; and
  .  follow detailed control procedures that are designed to ensure that we
     are delivering high quality solutions.

   Our objective is to become the leading provider of strategy-led Internet
professional services. Our business strategy for accomplishing this objective
includes continuing to attract and retain outstanding professionals, continuing
to serve cutting edge dot-com clients, enhancing and extending our service
offering and continuing to build the ZEFER brand.

   We were incorporated in Delaware in March 1999. Our principal executive
offices are located at 711 Atlantic Avenue, Boston, Massachusetts 02111 and our
telephone number is (617) 451-8000. Our world wide web address is
www.ZEFER.com. The information on our website is not incorporated by reference
into this prospectus.

   We have applied to register "ZEFER" as a trademark in the United States,
Canada and in the European Union. ZEFER 360(degrees) is an unregistered

</TABLE>

   The number of shares of our common stock that will be outstanding after this
offering excludes 4,627,111 shares subject to outstanding options as of
December 31, 1999 under our 1999 Incentive Plan and 1999 Stock Option Plan at a
weighted average exercise price of $1.38 per share and 39,555 additional shares
available for issuance under these plans as of such date. In February 2000, our
board of directors approved an amendment to our 1999 Incentive Plan increasing
the shares available for issuance under the plan by 20,000,000.

   Investing in our common stock involves risk. In particular, we have a
history of operating losses, incurred an operating loss of $34.0 million for
the period from our inception to December 31, 1999 and expect to continue to
incur operating losses in the future. In addition, after this offering, our
principal stockholder and our executive officers and directors will
beneficially own an aggregate of approximately 79.4% of our capital stock. If
these persons were to choose to act together, they would be able to control the
election of directors and all other matters submitted to our stockholders for
approval, as well as our management and affairs. Please see "Risk Factors."

                                  RISK FACTORS

   This offering involves a high degree of risk. You should consider carefully
the risks and uncertainties described below and the other information in this
prospectus, including the financial statements and related notes, before
deciding to invest in shares of our common stock. If any of the following risks
or uncertainties actually occurs, our business, financial condition and
operating results would likely suffer. In that event, the market price of our
common stock could decline and you could lose all or part of the money you paid
to buy our common stock.

                         Risks Relating To Our Business

Our future success is uncertain because we have a limited operating history

   We have a limited operating history in the new and rapidly changing Internet
professional services market. We were incorporated in March 1999 and acquired a
number of businesses during 1999, each of which had a limited operating
history. Accordingly, our historical results of operations may not reflect the
current nature of our service offering and you should not rely on them as an
indicator of our future performance. In particular, our larger work force and
the greater variety of services that we offer may affect our future results as
compared to our historical results.

We have a history of operating losses and expect to incur losses in the future

   We expect to continue to incur increasing sales and marketing, hiring and
training, infrastructure development and general and administrative expenses.
As a result, we will need to generate significant revenues to achieve
profitability. We cannot be certain whether or when this will occur because of
the significant risks and uncertainties that affect our business.

   We experienced a net loss of $30.5 million for the period from our inception
to December 31, 1999 and a pro forma net loss of $45.4 million for the year
ended December 31, 1999. The pro forma net loss gives effect to the results of
operations of the companies that we acquired as if we had acquired such
companies on January 1, 1999. The pro forma net loss includes net losses
incurred by these companies prior to the dates we acquired them, interest
expense on borrowings to finance the acquisitions, and expenses relating to
depreciation and amortization arising from the acquisitions. We expect to
continue to incur significant operating losses as we expand our business. If we
do achieve profitability, we may not be able to sustain or increase
profitability on a quarterly or annual basis in the future.

Our growth could be limited if we are unable to attract, develop and retain
personnel with management expertise, Internet expertise and consulting and
technical skills

   Because we are a professional services firm, the number and quality of our
professionals are critical to the services we offer. We believe that our
success in the highly competitive Internet professional services market depends
largely on our ability to attract, develop and retain highly skilled
professionals to manage, deliver and sell our services. Individuals with
management experience, Internet expertise and consulting and technical skills
are in short supply. Accordingly, we may not be able to hire or retain the
necessary number or mix of personnel to implement our business strategy.
Competition to hire from this limited pool of professionals is intense. We may
need to incur higher compensation expenses than we currently expect in order to
attract and retain qualified personnel.

Our markets are highly competitive and our failure to compete in them
successfully would limit our ability to maintain our existing clients or
attract new clients

   We compete in the rapidly evolving market of Internet professional service
providers. This market is highly competitive. Our competitors include a wide
variety of Internet-focused professional service firms, strategic management
consulting companies, traditional information technology service firms, systems

                                       5
<PAGE>


integration firms and internal IT departments of our prospective clients. Many
of our competitors have longer operating histories, better name recognition,
larger client bases and greater financial, technical, marketing and public
relations resources than we have. Because the Internet professional services
market has relatively low barriers to entry, we believe competition will
intensify as the market evolves. If we do not compete successfully, we will not
be able to maintain or increase our market share, which would result in serious
harm to our business.

Our results of operations would suffer if we are unable to keep pace with the
rapid technological change of the Internet, changing business methodologies and
evolving client requirements

   The Internet professional services industry is characterized by a rapidly
evolving technological landscape, evolving business methodologies and
constantly changing client requirements. The manner in which firms have
conducted business on the Internet has changed dramatically in the last few
years, and our future success depends in part on our ability to anticipate and
adapt to new changes.

We may be unable to successfully manage our growth, which would negatively
impact our business

   Since our founding, we have rapidly expanded our operations by hiring new
employees, making acquisitions, adding new clients, extending existing client
relationships and expanding our geographic markets. For instance, our revenues
increased from $2.6 million for the three months ended June 30, 1999 to $13.3
million for the three months ended December 31, 1999, and our employees
increased from 222 at June 30, 1999 to 481 at December 31, 1999. Our growth has
placed and will continue to place a significant strain on our management,
operating and financial systems and sales, marketing and administrative
resources. If we cannot effectively manage our expanding operations, we may not
be able to continue to grow or we may grow at a slower pace. Furthermore, our
operating costs may escalate faster than planned.

   To successfully manage our growth we must:

  .  attract and retain leading business, design, technical and project
     management talent;

  .  expand our training and development programs for our existing and new
     employees;

  .  improve our management, financial, human resource and information
     systems and controls; and

  .  build a base of intellectual capital that can be leveraged for client
     development and service delivery.

We may undertake additional acquisitions which may affect our ability to manage
and maintain our business, may result in adverse accounting treatment and may
be difficult to integrate into our business

   Since our inception, we have acquired a number of businesses. We may
undertake additional acquisitions of Internet professional service firms or
other complementary businesses in the future which could involve a number of
risks, including:

  .  the diversion of the attention of management and other key personnel;

  .  inability to effectively integrate the acquired business into our
     culture, client delivery methodology and other standards, controls,
     procedures and policies;

  .  inability to retain the management, key personnel and other employees of
     the acquired business;

  .  inability to retain the acquired company's customers; and

  .  the amortization of goodwill, which may adversely affect our reported
     results of operations.

   Client satisfaction or performance problems with an acquired business also
could affect our reputation as a whole. In addition, any acquired business
could significantly underperform relative to our expectations.

                                       6
<PAGE>

Our quarterly revenues and operating results are likely to vary, which may
cause the market price of our common stock to decline

   We expect our quarterly revenues and operating results to be volatile and
difficult to predict. They are likely to vary significantly from quarter to
quarter. Factors that may cause our results to fluctuate include:

  .  the amount and timing of demand by our clients for Internet professional
     services;

  .  cancellations or reductions in the scope of major projects; and

  .  the length of the sales cycle associated with our service offerings.


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


We generally enter into fixed-price contracts and risk incurring losses on
particular engagements if we miscalculate the time or resources needed to
complete them

   Approximately 90% of our revenues for the period from our inception through
December 31, 1999 was derived from fixed-price contracts. Because of the
complex nature of the services we provide, it is sometimes difficult to
accurately estimate the cost, scope and duration of particular client
engagements. If we underestimate the resources required by client engagements,
we may be required to devote additional resources to these engagements without
receiving additional compensation, which would adversely affect our results of
operations and financial condition.






The developing market for Internet professional services and the level of
acceptance of the Internet as a business medium will affect our business

   The market for Internet professional services is relatively new and is
evolving rapidly. Our future growth is dependent upon our ability to provide
Internet professional services that are accepted by our existing and future
clients as an integral part of their business models. The level of demand for
and acceptance of Internet professional services is highly uncertain and
dependent upon a number of factors, including:

  .  the growth in consumer access to and acceptance of new interactive
     technologies such as the Internet;

  .  the adoption of Internet-based business models by companies; and

  .  the development of technologies that facilitate two-way communication
     between companies and targeted audiences.

   Significant issues concerning the commercial use of Internet technologies
include security, reliability, cost, ease of use and quality of service. These
issues remain unresolved and may inhibit the growth of Internet business
solutions that utilize these technologies.

   Industry analysts and others have made many predictions concerning the
growth of the Internet as a business medium. These predictions should not be
relied upon. If the market for Internet professional services fails to develop,
or develops more slowly than expected, or if our services do not achieve market
acceptance, our business will not succeed and the value of your investment in
our common stock will decline.

We may be unable to redeploy our professionals effectively if engagements are
terminated unexpectedly, which would adversely affect our revenues

   Our clients can cancel or reduce the scope of their engagements with us on
short notice. If they do so, we may be unable to reassign our professionals to
new engagements without delay. The cancellation or reduction

                                       7
<PAGE>

in scope of an engagement could, therefore, reduce the utilization rate of our
professionals, which would have a negative impact on our financial condition
and results of operations.

A small number of our clients account for a significant portion of our
revenues, which may decline if we cannot keep or replace these client
relationships

   During the period from our inception through December 31, 1999, five clients
accounted for approximately 31% of our revenues. We anticipate that our results
of operations in any given period may continue for the foreseeable future to
depend to a significant extent upon revenues from a small number of clients. In
addition, we anticipate that such clients will continue to vary over time, so
that the achievement of our long-term goals will require us to obtain
additional significant clients on an ongoing basis. Either our loss of existing
clients or our failure to generate new clients will have an adverse effect on
our financial condition and results of operations.

Failure of computer systems and software to be year 2000 compliant could
increase our costs, disrupt our service and reduce demand from our clients

   We confront the year 2000 problem in two contexts.

   Our Clients. The failure of our clients to ensure that their operations are
year 2000 compliant could have an adverse effect on them, which in turn could
limit their ability to retain us as a third-party service provider or process
our invoices in a timely manner. In addition, clients or potential clients may
delay purchasing our services to the extent such clients or potential clients
are required to devote resources to resolving the year 2000 problem.

   Our Services. The solutions that we provide to our clients integrate
software and other technology from different providers. If there is a year 2000
problem with respect to a solution provided by us, it may be difficult to
determine whether the problem relates to services that we have performed or is
due to the software, technology or services of other providers. Furthermore, a
number of our contracts, including contracts with some of our largest clients,
contain express or implied warranties with respect to year 2000 readiness. As a
result, we may be subjected to year 2000-related lawsuits, whether or not the
services that we have performed are year 2000 compliant. We cannot be certain
what the outcomes of these types of lawsuits may be.

Our business may suffer if we have disputes with clients over our right to
reuse intellectual property developed during client engagements

   Part of our business involves the development of software applications for
discrete client engagements. Ownership of client-specific software is generally
held by the client, although we typically retain the right to reuse some of the
processes and other intellectual property developed in connection with client
engagements. Issues relating to the right to use intellectual property can be
complicated. Accordingly, disputes may arise that could adversely affect our
ability to reuse applications, processes and other intellectual property that
result from particular client engagements. Such disputes could damage our
relationships with our clients and our business reputation, divert our
management's attention and have an adverse effect on our ability to grow our
business.

Intellectual property infringement claims against us, even without merit, could
cost a significant amount of money to defend and may divert management's
attention

   As the number of Internet applications in our target market increases and
the functionality of these applications overlaps, we may become subject to
infringement claims. We cannot be certain that our services, the solutions that
we deliver or the software used in our solutions do not or will not infringe
valid patents, copyrights or other intellectual property rights held by third
parties. If there is infringement, we could be liable for substantial damages.
Infringement claims, even if without merit, can be time consuming and expensive
to defend. They may divert management's attention and resources and could cause
service implementation delays. They also could require us to enter into costly
royalty or licensing agreements.

                                       8
<PAGE>

We may need additional capital, which may not be available to us, and which, if
raised, may dilute your ownership interest in us

   We used $18.5 million of net cash in operating activities for the period
from our inception to December 31, 1999 and expect to continue to require cash
for our operating activities for the foreseeable future. After this offering we
will remain highly leveraged and may need to raise additional funds through
public or private equity or debt financing in order to:

  .  fund our working capital requirements;

  .  support additional capital expenditures;

  .  service our existing debt;

  .  take advantage of acquisition or expansion opportunities; or

  .  develop new services.

   If we cannot obtain financing on terms acceptable to us or at all, we may be
forced to curtail some or all of these activities, which could impair our
growth. Any additional capital raised through the sale of equity will dilute
your ownership interest in us and may be on terms that are unfavorable to you.

                        Risks Relating To This Offering



After this offering, our executive officers, directors and principal
stockholder will still be able to control all matters submitted to stockholders
for approval

   When this offering is completed, our executive officers, directors and
principal stockholder will, in the aggregate, beneficially own shares
representing approximately 79.4% of our capital stock. As a result, these
persons, if they were to choose to act together, will be able to control all
matters submitted to our stockholders for approval, as well as our management
and affairs. For example, these persons, if they were to choose to act
together, will control the election of directors and any merger, consolidation
or sale of all or substantially all of our assets.

Antitakeover defenses that we have in place could delay or prevent an
acquisition and could adversely affect the price of our common stock because
purchasers cannot acquire a controlling interest

   Provisions of our certificate of incorporation and bylaws and provisions of
Delaware law could delay, defer or prevent an acquisition or change of control
of us or otherwise adversely affect the price of our common stock. These
provisions may deprive you of the opportunity to sell your shares at a premium
over prevailing prices. This potential inability to obtain a control premium
could reduce the market price of our common stock. Please refer to "Description
of Capital Stock" for a more detailed discussion of these and other provisions.


Purchasers in this offering will suffer immediate and substantial dilution of
their investment

   Purchasers of common stock in this offering will pay a price per share that
substantially exceeds the per share value of our tangible assets after
subtracting our liabilities and the per share price paid by our existing
stockholders and by persons who exercise currently outstanding options to
acquire our common stock. Accordingly, you will experience immediate and
substantial dilution of approximately $11.12 per share, representing the
difference between our pro forma net tangible book value per share after giving
effect to this offering and the initial public offering price. In addition,
purchasers of common stock in this offering will have contributed approximately
46.4% of the aggregate price paid by all purchasers of our stock but will own
only approximately 8.3% of our common stock outstanding after this offering.
See "Dilution."

Our stock price could be volatile, which could result in substantial losses for
investors purchasing shares in this offering

   The trading price of our common stock is likely to be volatile. The stock
market in general and the market for technology and Internet-related companies
in particular have experienced extreme volatility. This volatility has often
been unrelated to the operating performance of particular companies. We cannot
be sure that an active public market for our common stock will develop or
continue after this offering. Investors may not be able to sell their common
stock at or above our initial public offering price. The price for our common
stock will be determined in the marketplace and may be influenced by many
factors, including:

  .  variations in our financial results or those of companies that are
     perceived to be similar to ours;

  .  changes in earnings estimates by industry research analysts;

  .  investors' perceptions of us; and

  .  general economic, industry and market conditions.

Substantial sales of our common stock could cause our stock price to decline


   If our existing stockholders sell a large number of shares of our common
stock or the public market perceives that existing stockholders might sell
shares of common stock, the market price of the common stock could
significantly decline. All of the shares offered under this prospectus will be
freely tradable without restriction or further registration under the federal
securities laws unless purchased by our "affiliates" as that term is defined in
Rule 144 under the Securities Act of 1933. Of the remaining 43,995,767 shares
outstanding at the time of this offering:

  .  4,571,761 shares may be sold 90 days after the effective date of this
     offering; and

  .  33,832,246 additional shares may be sold upon the expiration of 180-day
     lock-up agreements.

   Existing stockholders holding an aggregate of approximately 40,000,000
shares of common stock have the right to require us to register their shares of
common stock with the Securities and Exchange Commission. If we register their
shares of common stock, they can sell those shares in the public market.

   After this offering, we intend to register approximately 25,166,666 shares
of our common stock that we have issued or may issue under our stock plans.
Once we register these shares, they can be freely sold in the public market
upon issuance, subject to the "lock-up" agreements described above and the
restrictions imposed on our affiliates under Rule 144.

               This Document Includes Forward-Looking Statements

   This prospectus contains forward-looking statements that involve substantial
risks and uncertainties. In some cases you can identify these statements by
forward-looking words such as "anticipate," "believe," "could," "estimate,"
"expect," "intend," "may," "should," "will," and "would" or similar words. You
should read statements that contain these words carefully because they discuss
our future expectations, contain projections of our future results of
operations or of our financial position or state other "forward-looking"
information. We believe that it is important to communicate our future
expectations to our investors. However, there may be events in the future that
we are not able to accurately predict or control. The important factors listed
above, as well as any cautionary language in this prospectus, provide examples
of risks, uncertainties and events that may cause our actual results to differ
materially from the expectations we describe in our forward-looking statements.
Before you invest in our common stock, you should be aware that the occurrence
of the events described in these risk factors and elsewhere in this prospectus
could have an adverse effect on our business, results of operations and
financial position.

                                USE OF PROCEEDS

   We estimate that the net proceeds from our sale of 4,000,000 shares of
common stock will be approximately $42.8 million, assuming an initial public
offering price of $12.00 per share and after deducting estimated underwriting
discounts and our estimated offering expenses. If the underwriters' over-
allotment option is exercised in full, we estimate that our net proceeds will
be approximately $49.5 million.

   We expect to use a portion of the net proceeds from this offering to repay
approximately $19.4 million of outstanding indebtedness under a revolving line
of credit with Harris Trust and Savings Bank, which indebtedness was incurred
on July 16, 1999 to fund operating losses, bears interest at the prime lending
rate, 8.5% as of January 31, 2000, is guaranteed by GTCR and is due on demand.


   We expect to use the remaining $23.4 million of net proceeds, together with
cash from operations, for working capital and other general corporate purposes,
including possible acquisitions of businesses, products and technologies and
minority investments in some of our clients. From time to time we engage in
discussions with potential acquisition candidates. However, we have no current
plans, commitments or agreements with respect to any acquisitions or
investments and we may not make any acquisitions or investments.

   To the extent that the net proceeds from this offering exceed $42.8 million,
we will use additional proceeds for the following purposes:

  .  first, to repay outstanding subordinated indebtedness owed to an
     affiliate of GTCR. We incurred $12.8 million of such indebtedness in
     November 1999 to fund operating losses and repurchase shares of stock
     held by GTCR and expect to incur an additional $9.1 million of
     indebtedness to fund operations during the first quarter of 2000. The
     aggregate indebtedness bears interest at a rate of 12.0% per annum and
     currently matures upon the closing of this offering. We are negotiating
     with GTCR to extend the maturity date of the loan; and

  .  second, to redeem on a pro rata basis shares of our common stock issued
     to holders of class A preferred stock upon exchange of their shares of
     class A preferred stock. The redemption of such shares of common stock
     will have the ultimate effect of reducing the number of shares of common
     stock that will be held by the holders of our class A preferred stock
     following this offering. The per share redemption price will be the
     initial public offering price. See "Certain Transactions" for a
     discussion of this exchange and redemption.

   Pending use of the net proceeds, we intend to invest these proceeds in
short-term, investment grade, interest-bearing instruments.

                                DIVIDEND POLICY

   We have never declared or paid any cash dividends on our shares of common
stock. We intend to retain future earnings, if any, to finance our growth
strategy. We do not anticipate paying cash dividends on our common stock in the
foreseeable future. Payment of future dividends, if any, will be at the
discretion of our board of directors after taking into account various factors,
including our financial condition, our operating results, our current and
anticipated cash needs, restrictions in any future financing agreements and our
plans for expansion.

   Some of our existing lines of credit prohibit the declaration or payment of
cash dividends to our stockholders so long as any indebtedness under these
lines is outstanding. See "Management's Discussion and Analysis of Historical
Financial Condition and Results of Operations--Liquidity and Capital Resources"
and note 7 of the ZEFER Corp. financial statements.

   The following table sets forth our actual, pro forma and pro forma as
adjusted capitalization as of December 31, 1999. The pro forma information
reflects:

  .  the issuance during the first quarter of 2000 of an aggregate of 20,863
     shares of class A preferred stock to existing holders of class A
     preferred stock for $18,658,000 pursuant to a Securities Purchase
     Agreement, dated March 23, 1999;

  .  the exchange upon the closing of this offering of all outstanding shares
     of class A preferred stock, including related accrued and unpaid
     dividends, for 3,933,166 shares of common stock at an exchange rate
     based on an assumed initial public offering price of $12.00 per share;

  .  the filing of a certificate of amendment upon the closing of this
     offering that eliminates the class A preferred stock and authorizes
     150,000,000 shares of common stock and 5,000,000 shares of undesignated
     preferred stock; and

  .  the conversion upon the closing of this offering of a $2.0 million
     promissory note issued to Renaissance Worldwide, Inc. into 208,333
     shares of common stock.

   The pro forma as adjusted information reflects:

  .  receipt of the estimated net proceeds from the sale by us of 4,000,000
     shares of common stock in this offering, after deducting the estimated
     underwriting discounts and commissions and estimated offering expenses;
     and

  .  the application of a portion of the net proceeds to repay $19.4 million
     of outstanding bank indebtedness under a revolving line of credit.

   The share numbers exclude 4,627,111 shares of common stock issuable upon
exercise of stock options outstanding as of December 31, 1999 at a weighted
average exercise price of $1.38 per share and 39,555 shares of common stock
available for issuance under our 1999 Incentive Plan and 1999 Stock Option Plan
as of December 31, 1999. This table should be read in conjunction with

                                    DILUTION

   The pro forma net tangible book value of our common stock as of December 31,
1999 was approximately $(0.5) million, or $(0.01) per share. Pro forma net
tangible book value per share represents the amount of our total tangible
assets reduced by our total liabilities, divided by the number of shares of
common stock outstanding as of December 31, 1999, assuming (a) the exchange of
all outstanding shares of class A preferred stock, including related accrued
and unpaid dividends, for 3,933,166 shares of common stock at an exchange rate
based on an assumed initial public offering price of $12.00 per share and (b)
the conversion of a $2.0 million promissory note issued to Renaissance
Worldwide, Inc. into 208,333 shares of common stock. After giving effect to the
sale by us of 4,000,000 shares of common stock in this offering, deducting the
estimated underwriting discounts and commissions and estimated offering
expenses and applying a portion of the net proceeds to repay $19.4 million of
outstanding bank indebtedness under a revolving line of credit, our pro forma
net tangible book value as of December 31, 1999 would have been approximately
$42.3 million, or $0.88 per share. This represents an immediate increase in pro
forma net tangible book value of $0.89 per share to existing stockholders and
an immediate dilution in pro forma net tangible book value of $11.12 per share
to purchasers of common stock in this offering.

   If the initial public offering price is higher or lower, the dilution to new
investors will be greater or less, respectively. Dilution is determined by
subtracting pro forma net tangible book value per share after the offering from
the amount of cash paid by a new investor for a share of common stock. The
following table illustrates the per share dilution to new investors:

   As of December 31, 1999, there were options outstanding to purchase a total

are exercised, there will be additional dilution to new investors.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                       OF PRO FORMA RESULTS OF OPERATIONS

   The following discussion and analysis of our pro forma results of operations
should be read in conjunction with "Selected Pro Forma Financial Data" and our
financial statements and notes thereto appearing elsewhere in this prospectus.
This discussion and analysis contains forward-looking statements that involve
risks, uncertainties and assumptions. Our actual results may differ materially
from those anticipated in these forward-looking statements as a result of a
number of factors, including those set forth under "Risk Factors" and elsewhere
in this prospectus. For an overview of our historical financial condition and
results of operations, as well as a discussion of our liquidity and capital
resources, recent accounting pronouncements, market risk disclosure and year
2000 impact, please see "Management's Discussion and Analysis of Historical
Financial Condition and Results of Operations." All of the operating results
discussed below are presented on a pro forma basis.

Overview

   We were organized on March 18, 1999 for the purpose of continuing the
business of our predecessor, which we refer to as Original ZEFER. Original
ZEFER was established on March 19, 1998 to provide strategy-led Internet
consulting services. Original ZEFER had revenues of $0.6 million for the period
from its inception to December 31, 1998, and $0.3 million for the three months
ended March 31, 1999.

   We have completed the following strategic acquisitions that have enabled us
to gain critical resources and delivery capabilities, expand into new
geographic regions and deliver larger projects:

  .  Spyplane. On May 14, 1999, we acquired all of the outstanding membership
     interests of Spyplane LLC, a San Francisco-based digital branding and
     design firm. Digital branding is the adaptation of a brand name or logo
     onto a digital platform. Spyplane had revenues of $0.3 million for the
     period beginning on its inception, May 7, 1998 and ending on December
     31, 1998 and revenues of $0.5 million for the period from January 1,
     1999 to May 14, 1999.

  .  The Divisions of Renaissance. On May 28, 1999, we acquired two divisions
     of Renaissance Worldwide, Inc. One division was engaged in web
     application development and the other division was engaged in customer
     relationship management consulting and implementation. The Divisions of
     Renaissance had combined revenues of $13.8 million for the year ended
     December 31, 1998 and $3.9 million for the five months ended May 28,
     1999.

  .  Waite & Company. On September 13, 1999, we acquired Waite & Company,
     Inc., a Boston-based strategic marketing and management-consulting firm.
     Waite & Company had revenues of $3.3 million for the year ended December
     31, 1998 and $2.9 million for the period from January 1, 1999 to
     September 13, 1999.

   We are a strategy-led Internet consulting and implementation firm. We derive
our revenues primarily from providing Internet consulting and implementation
services to our clients. We expect that our revenues will be driven primarily
by the number, scope and pricing of our client engagements along with our
capacity to deliver such engagements. Our operating results will be determined
primarily by our headcount, utilization of billable consultants and level of
selling, general and administrative and other operating expenditures.

   A substantial majority of our pro forma revenues for 1999 was derived from
services performed on a fixed-price basis, and we expect to continue to derive
a substantial majority of our revenue from fixed-price contracts in the future.
The balance of our revenues are derived from time and materials engagements. A
majority of our engagements last from three to six months. To determine the
proposed fixed price of an engagement, we use an estimation process that takes
into account:

  .  the type and overall complexity of the project;

  .  the anticipated number and type of consultants needed and their
     associated billing rates; and

  .  the estimated duration of and risks associated with the engagement.

                                       16
<PAGE>


   All fixed-price proposals must receive the approval of a member of our
senior management team. We recognize revenues from fixed-price engagements
using the percentage of completion method, based on the ratio of costs incurred
to date to the total estimated project costs. We calculate project costs based
on the direct payroll and associated employee benefits of the consultants on
the engagement, plus any direct, unbilled out-of-pocket expenses. Finance
personnel meet regularly with project managers to ensure that the budgeted
costs to complete the engagement, which are used to calculate revenue
recognition, reflect the current actual status of the project and the updated
anticipated costs to complete the engagement. We make provisions for estimated
losses on engagements during the period in which such losses become probable
and can be reasonably estimated. These losses have not been significant to
date. We sometimes recognize revenues in advance of billing our customers and
therefore maintain a significant unbilled receivables balance. We make
provisions for uncollectible accounts receivable, which have not been
significant to date. We offset out-of-pocket expenses reimbursed by the client
against the expenses incurred and do not recognize such reimbursements as
revenues.

   Cost of services consists primarily of salaries and associated employee
benefits for personnel directly associated with the delivery of services in
client engagements and non-reimbursed out-of-pocket expenses incurred by such
consultants. We expect that cost of services will increase over time in
absolute dollars in conjunction with wage increases and inflation, as well as
increases in the number of billable professionals related to volume.

   Hiring and training expenses consist primarily of salaries and related
expenses associated with attracting, recruiting, training and retaining
qualified professionals. We expect these expenses to increase over time in
absolute dollars as our employee base grows and we complete the construction of
a 12,000 square foot innovation and training facility.

   Research and innovation expenses consist primarily of (1) salaries and
related employee benefits of employees assigned directly to internal research
and development projects, as well as direct expenses for these projects, such
as special equipment, software and travel-related expenses; (2) the costs
associated with the dedicated knowledge management team as well as the unified
services team, which is responsible for developing and enhancing our ENABLE
methodology; and (3) the expense and fees associated with our board of
advisors, which consists of experts in the fields of study relevant to the
development of innovative thinking. Our dedicated knowledge management team is
a group of our professionals whom we have assigned to identify methodologies,
best practices and other processes that we have developed for use throughout
our organization in ongoing and future client engagements.We expect research
and innovation costs to increase in both absolute dollars and as a percentage
of revenues in the near term as we seek to enhance our competitive position.

   Sales and marketing expenses consist primarily of salaries, commissions and
related expenses for employees dedicated to our sales and marketing efforts.
Additionally, we include costs associated with advertising, public relations,
seminars, mailings, Internet campaigns, speaking engagements and other
sponsored marketing events and promotions in sales and marketing expenses. We
expect sales and marketing expenses to increase in absolute dollars as we
expand our direct sales force and promotional efforts.

   General and administrative expenses consist primarily of human resources,
information technology, finance, legal and administrative personnel and
facilities and general operating costs. We expect these expenses to increase in
absolute dollars to support the growth of our business.

   Depreciation and amortization expenses consist primarily of the amortization
of goodwill and other intangibles related to acquisitions. They also include
depreciation of property and equipment.

Pro Forma Results of Operations

 Twelve Months Ended December 31, 1999 Compared to Twelve Months Ended December
 31, 1998

   Revenues for the year ended December 31, 1999, as compared to the year ended
December 31, 1998, increased by $15.1 million, or 84.0%, to $33.1 million from
$18.0 million. The increase in revenues was primarily a result of an increase
in the number of client engagements and an expansion of our service offerings,

along with the increased scope and complexity of engagements.

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

   The following discussion and analysis of our financial condition and
results of operations should be read in conjunction with "Selected Financial
Data," "Management's Discussion and Analysis of Pro Forma Results of
Operations--Overview" and our financial statements and notes thereto appearing
elsewhere in this prospectus. This discussion and analysis contains forward-
looking statements that involve risks, uncertainties and assumptions. Our
actual results may differ materially from those anticipated in these forward-
looking statements as a result of a number of factors, including those set
forth under "Risk Factors" and elsewhere in this prospectus.

Historical Results of Operations

   Though we did not begin operations until March 18, 1999, our predecessors,
Original ZEFER and the divisions of Renaissance, did have prior operating
histories.


Original ZEFER

 Period from Our Inception (March 18, 1999) to December 31, 1999 Compared to
 Period from Original ZEFER's Inception (March 19, 1998) to December 31, 1998

   Revenues. Revenues for the period from our inception to December 31, 1999
increased by $24.7 million to $25.3 million from $0.6 million for the period
from Original ZEFER's inception to December 31, 1998. The increase in revenues
was primarily a result of an increase in the number of client engagements and
an expansion of our service offerings, along with the increased scope and
complexity of our engagements, during 1999.

   Operating Expenses. Costs of services increased by $15.3 million to $15.7
million from $0.5 million primarily due to the increase in the number of
billable professionals as we expanded our capacity to meet the increase in
demand for Internet consulting and implementation services. Hiring and
training costs increased to $5.5 million from zero primarily due to an
increase in our recruiting efforts, including expansion of our human resources
department, an increase in our use of external recruiters and the assimilation
and training of more employees. We initiated our research and innovation
activities during 1999, incurring research and innovation expenses of $1.8
million in 1999. Most of our research and innovation expenses related to the
development of our proprietary ENABLE methodology and knowledge management
infrastructure. Sales and marketing expenses for 1999 increased by $6.9
million to $7.0 million from $0.1 million as we began to build our sales and
marketing organization during 1999 in order to support rapid growth. General
and administrative expenses for the period increased by $28.6 million to $29.1
million from $0.5 million. This increase was primarily due to increased
amortization of goodwill and other intangibles of approximately $8.1 million
during 1999 related to acquisitions and increased depreciation and
amortization of approximately $2.5 million resulting from increased purchases
of computer equipment, software and furniture and fixtures required to support
the increase in headcount. Additional increases in general and administrative
expenses reflected our investment in the infrastructure required to rapidly
scale our business.

   Interest and Other Expense. Interest and other expense increased by $2.3
million from zero primarily due to the 1999 interest expense of approximately
$1.0 million on our class A preferred stock. Additional increases in interest
expense are due to increased indebtedness when the company took on the
additional line of credit and Subordinated Debt payable to GTCR during the
fourth quarter of 1999. The benefit from taxes increased by $5.8 million from
zero primarily due to the application of net operating loss carryforwards
against deferred tax liabilities recorded in connection with acquisitions.

 Four Months Ended April 30, 1999 Compared to Period from Inception (March 19,
 1998) to April 30, 1998

   The four month period ended April 30, 1999 and the forty-day period from
the Original ZEFER's inception to April 30, 1998 are not comparable periods.
The amounts described below for the forty-day period ended April 30, 1998
would have been higher if a comparable four month period were used.

                                      20
<PAGE>


   Original ZEFER was organized on March 19, 1998 and did not commence
generating revenues until June 1998. Accordingly, revenues for the four months
ended April 30, 1999 increased to $0.5 million from zero for the period from
inception to April 30, 1998.

   Original ZEFER did not begin incurring operating expenses until April 1998.
Accordingly, cost of services for the four months ended April 30, 1999
increased to $0.6 million from zero for the period from inception to April 30,
1998. Sales and marketing expenses for the four months ended April 30, 1999
increased to $0.1 million from zero for the period from inception to April 30,
1998. General and administrative expenses increased by $2.0 million to $2.0
million for the four month period ended April 30, 1999 from $38,000 for the
period from inception to April 30, 1998.

   Interest and other expense increased to $19,000 from zero due to the fact
that the Company took on capital lease commitments during the second half of
1998.

Divisions of Renaissance

 Period from Our Inception (March 18, 1999) to December 31, 1999 Compared to
 the Twelve Months Ended December 31, 1998

   The period from our inception to December 31, 1999 and the twelve-month
period ended December 31, 1998 are not comparable periods. The amounts
described below for the period from our inception to December 31, 1999 would
have been higher if a comparable twelve-month period had been used.

   Revenues. Revenues for the period from inception to December 31, 1999
increased by $11.5 million to $25.3 million from $13.8 million. The increase in
revenues was primarily a result of an increase in the number of client
engagements and an expansion of our service offerings, along with the increased
scope and complexity of engagements.

   Operating Expenses. Costs of services increased by $5.6 million to $15.7
million from $10.1 million primarily due to the increase in the number of
billable professionals as we expanded our capacity to meet the increase in
demand for Internet consulting and implementation services. Hiring and training
costs increased by $5.4 million to $5.5 million from $0.1 million primarily due
to an increase in our recruiting efforts, including expansion of our human
resources department, an increase in our use of external recruiters and the
assimilation and training of more employees. We initiated our research and
innovation activities during 1999, incurring research and innovation expenses
of $1.8 million. Most of our research and innovation expenses related to the
development of our proprietary ENABLE methodology and knowledge management
infrastructure. Sales and marketing expenses for the period increased by $2.9
million to $7.0 million from $4.1 million as we replaced the sales and
marketing organization which supported the divisions of Renaissance but which
was not acquired in the acquisition. General and administrative expenses for
the period increased by $25.9 million to $29.1 million from $3.2 million. This
increase was primarily due to increased amortization of goodwill and other
intangibles of approximately $8.1 million during 1999 related to acquisitions
and increased depreciation and amortization of approximately $2.5 million
resulting from increased purchases of computer equipment, software and
furniture and fixtures required to support the increase in headcount.
Additional increases in general and administrative expenses reflected our
investment in the infrastructure required to rapidly scale our business.

   Interest and Other Expense. Interest and other expense increased by $1.9
million to $2.3 million from $0.4 million primarily due to the interest expense
of approximately $1.0 million on our class A preferred stock. Additional
increases in interest expense are due to increased indebtedness when the
Company took on the additional line of credit and the Subordinated Debt payable
to GTCR during the fourth quarter of 1999. The benefit from taxes increased by
$5.8 million from zero primarily due to the application of net operating loss
carryforwards against deferred tax liabilities recorded in connection with
acquisitions.

<PAGE>


 Five Months Ended May 28, 1999 Compared to Five Months Ended May 28, 1998

   Revenues. Revenues for the five months ended May 28, 1999 decreased by $0.6
million to $3.9 million from $4.5 million for the five months ended May 28,
1998. This decrease was primarily due to a decrease in the number of
engagements delivered by the web application division, partially offset by the
additional revenues generated by the creation of the customer relationship
management (CRM) division.

   Operating Expenses. Cost of services increased by $0.9 million to $4.8
million for the five-month period ended May 28, 1999 from $3.9 million for the
five-month period ended May 28, 1998. This increase was primarily due to an
increase in the number of billable professionals in the CRM division. Hiring
and training costs increased by $0.1 million to $0.2 million for the five-month
period ended May 28, 1999 from $0.1 million for the five-month period ended May
28, 1998 primarily due to increased hiring and training of billable CRM
professionals. Sales and marketing decreased by $0.1 million to $1.0 million
for the five-month period ended May 28, 1999 from $1.1 million for the five-
month period ended May 28, 1998. This decrease was primarily due to the
decrease in commissions due to a decrease in revenues earned by the web
application division, partially offset by increased commissions due to an
increase in revenues in the CRM division. General and administrative expenses
increased by $1.5 million to $2.7 million for the five-month period ended May
28, 1999 from $1.2 million for the five-month period ended May 28, 1998. This
increase was primarily due to an increase in the number of billable
professionals in the CRM division.

   Interest and Other Expenses. Interest and other expenses increased by $0.4
million to $0.4 million for the five-month period ended May 28, 1999 from
$33,000 for the five-month period ended May 28, 1998. This increase was
primarily due to the fact that the divisions of Renaissance took additional
indebtedness during the second half of 1998.

 Year Ended December 31, 1998 Compared to Year Ended December 31, 1997

   Revenues. Revenues for the year ended December 31, 1998 increased by $4.3
million to $13.8 million from $9.5 million for the year ended December 31,
1997. This increase was primarily due to the establishment of the customer
relationship management practice in 1998.

   Operating Expenses. Cost of services increased by $5.6 million to $10.1
million for the year ended December 31, 1999 from $4.5 million for the year
ended December 31, 1997. This increase was primarily due to an increase in the
number of billable professionals due to the establishment of the CRM division
in March 1998. Hiring and training costs increased to $0.1 million for the year
ended December 31, 1998 primarily due to the hiring and training of billable
CRM professionals. Sales and marketing increased by $3.5 million to
$4.1 million for the year ended December 31, 1998 from $0.6 million for the
year ended December 31, 1997. This increase was primarily due to the
development of a dedicated sales force. General and administrative expenses
increased by $1.5 million to $2.7 million for the five-month period ended May
28, 1999 from $1.2 million for the five-month period ended May 28, 1998. This
increase was primarily due to an increase in the number of billable
professionals in the CRM division.

   Interest and Other Expenses. Interest and other expenses increased by $0.4
million to $0.4 million for the year ended December 31, 1999 from zero. This
increase was primarily due to an increase in indebtedness taken on by the
divisions of Renaissance during 1998.


Liquidity and Capital Resources

   Since inception we have financed our operations and capital expenditures
primarily through the sale of common and preferred stock and capital lease and
other debt financing. As of December 31, 1999, we had raised $29.2 million of
capital from the sale of common and preferred stock. As of December 31, 1999,
we had $1.3 million in cash and cash equivalents. We expect that accounts
receivable will continue to increase proportionately to the extent our revenues
continue to rise. Any such increase that occurs at a greater rate than
increases in revenues is likely to have an adverse effect on cash flows from
operating activities. Our billings for the quarter ended December 31, 1999
totaled $13.6 million. These amounts include billings to clients for out-of-
pocket expenses that are reimbursed by clients which are not included in
recognized revenues. Our gross accounts receivable balance of $10.7 million at
December 31, 1999 represents 72 days of billings for the quarter.

   We have a revolving line of credit for $20.0 million with Harris Bank and
Trust Company. Borrowings under this line of credit bear interest at the prime
lending rate (8.5% at December 31, 1999). All borrowings under this line are
guaranteed by GTCR. As of December 31, 1999, there were outstanding borrowings
under this line of credit in the amount of $19.4 million. We intend to repay
the outstanding balance under this line of credit with a portion of the net
proceeds of this offering. We also have a revolving line of credit for $0.2
million with Silicon Valley Bank East. Borrowings under this line of credit
bear interest at the prime lending rate plus 0.5% and are collateralized by all
assets, as defined. The agreement establishing this line of credit requires
that we comply with restrictive covenants, including minimum levels of working
capital and tangible net worth. As of December 31, 1999, we were not in
compliance with either of our financial covenants and were in receipt of a
waiver from the bank. On February 16, 2000, we repaid in full the outstanding
balance under this line of credit. We also have a capital equipment line with
TLP Leasing, Inc. pursuant to which we have financed computer equipment and
office furniture. Borrowings under this capital equipment line bear interest at
11.0% per annum. As part of the consideration for our acquisition of Spyplane,
we issued to the former members of Spyplane promissory notes in the aggregate
principal amount of $980,000. These notes bear interest at a rate of 8.0% per
annum. One half of the accrued interest plus $180,000 of the outstanding
principal, or an aggregate of $220,000, is payable on May 14, 2000. The
remaining unpaid principal and interest on the notes is due on May 14, 2001. As
part of the consideration for our acquisition of the divisions of Renaissance
the Company issued to Renaissance Worldwide Inc. a promissory note in the
aggregate principal amount of $2.0 million. The note bears interest at a rate
equal to the 30-day LIBOR (5.8% at December 31, 1999) plus 2.0% per annum and
interest is payable quarterly through May 2002. Principal is payable in eight
quarterly installments commencing May 2000. At the option of Renaissance, the
principal amount outstanding under the Renaissance note is convertible to
common stock of the Company at the conversion price equal to 80% of the IPO
price.

   On November 24, 1999, we entered into a loan agreement with GTCR Capital
Partners, LP, an affiliate of GTCR. The loan agreement provides for up to $32.2
million of borrowings, of which we borrowed $12.8 million on November 24, 1999
to fund operations. We currently intend to borrow $9.1 million during the first
quarter of 2000. Borrowings under this loan agreement bear interest at 12.0%
per annum. Interest is payable quarterly in arrears beginning December 31,
1999. The loan becomes due on the earliest of November 24, 2004, changes in
control specified in the related loan agreement or the completion of our
initial public offering. We currently anticipate amending our loan agreement to
extend the maturity date beyond the completion date of our initial public
offering. In addition, should we dispose of any assets or subsidiaries for net
proceeds in excess of $0.1 million, we must apply the net proceeds of such
disposition to prepay the loan. Borrowings are secured by substantially all of
our assets.

   During the period from inception (March 18, 1999) through December 31, 1999,
our operating activities used $18.5 million of cash. Net cash used by operating
activities during this period resulted from a net loss of $30.5 million and
increases in unbilled receivables of $3.0 million, prepaid expenses and other
current assets of $1.4 million and a deferred tax benefit of $5.8 million.
These uses of cash were partially offset by increases in accounts payable and
accrued expenses of $4.6 million, and $5.5 million, respectively, and non-cash
charges relating to depreciation and amortization of $10.6 million and non-cash
interest charges of $1.4 million. The increase in accounts receivable was
primarily attributable to increased volume of revenues and accounts receivable
purchased from acquired entities.

   During the period from inception through December 31, 1999, our investing
activities used $39.7 million in cash. Net cash used by investing activities
during this period resulted primarily from cash paid for the acquisitions of
Original ZEFER, Spyplane, LLC, the divisions of Renaissance and Waite &
Company, Inc. totaling $26.3 million, capital expenditures of $9.0 million and
an increase in long-term other assets of $4.5 million. The capital expenditures
were primarily for computer equipment and software required by our increase in
headcount and furniture and fixtures related to the build-out of our leased
facilities. We expect that capital expenditures will continue to increase to
the extent we continue to increase our headcount, open additional offices,
invest in research and innovation and generally expand our operations.
Additionally, while we currently have no plans to acquire additional
businesses, future investing activities may include the acquisition of
businesses.

                                       23
<PAGE>


   During the period from inception through December 31, 1999, our financing
activities provided $59.6 million in cash. Net cash provided by financing
activities during this period resulted from net borrowings on a line of credit
of $19.4 million, proceeds from the issuance of redeemable preferred stock of
$24.2 million, proceeds from the issuance of subordinated debt to GTCR of $11.1
million, proceeds from the issuance of common stock of $4.5 million and
proceeds from the repayment of subscriptions receivable of $0.5 million.

   We believe that the net proceeds from this offering, together with our
existing cash resources and our projected cash flow from operations, will be
sufficient to fund our planned operations for at least the next

twelve months. Our ability to fund operations beyond twelve months will be
dependent upon the success of our operations and our future prospects which, in
turn, will affect our ability to raise debt or equity on commercially
reasonable terms. However, we may require significant additional funds for
possible future acquisitions of businesses, products or technologies
complementary to our business. If additional funds are required, we may raise
such funds from time to time through public or private sales of equity or from
borrowings. We currently have no plans for further equity offerings but may
undertake such offerings depending upon our results of operations, capital
requirements and the state of the economy and capital markets.

Recent Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
Accounting for Derivative Instruments and Hedging Activities. This statement
establishes accounting and reporting standards for derivative instruments,
including derivative instruments embedded in other contracts, and for hedging
activities. It requires an entity to recognize all derivatives as either assets
or liabilities in the balance sheet and measure those instruments at fair
value. Pursuant to SFAS No. 137, Accounting for Derivative Instruments and
Hedging Activities--Deferral of the Effective Date of FASB Statement No. 133,
SFAS No. 133 is effective for all quarters of fiscal years beginning after June
15, 2000. SFAS No. 133 is not expected to have a material impact on our
financial statements.

   In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-1, Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use. SOP 98-1 requires costs associated with
internal use software to be charged to operations as incurred until
capitalization criteria set forth in SOP 98-1 are met. SOP 98-1 became
effective January 1, 1999. The adoption of this statement did not have a
material impact on our financial position or results of operations.

Market Risk Disclosure

   We are exposed to market risk from changes in interest rates primarily
through our borrowing activities. Our ability to finance future acquisitions
may be impacted if we are unable to obtain appropriate financing at acceptable
rates.

   In July, 1999 we entered into a $20.0 million unsecured demand line of
credit with a bank of which $19.4 million was outstanding as of December 31,
1999. Borrowings on the line bear interest at the prime lending rate, 8.5% at
December 31, 1999.

   To date, we have not utilized derivative financial instruments or derivative
commodity instruments. We do not expect to employ these or other strategies to
hedge market risk in the foreseeable future. We do invest our cash in money
market funds, which are subject to minimal credit and market risk. We believe
the market risks associated with these financial instruments are immaterial.

Year 2000 Impact

   We have not experienced any problems with our computer systems relating to
distinguishing twenty-first century dates from twentieth century dates, which
generally are referred to as year 2000 problems. We are also not aware of any
material year 2000 problems with our clients or vendors. Accordingly, we do not
anticipate incurring material expenses or experiencing any material operational
disruptions as a result of any year 2000 problems.

                                    BUSINESS

Overview

   We provide strategy-led Internet consulting, software application
development and implementation services to dot-com and traditional companies to
enable them to effectively use the Internet in their businesses. The growth of
the Internet economy has created opportunities for many businesses to
significantly improve cost efficiencies, create revenue growth and redeploy
assets in accordance with new business models. We assist clients in identifying
business objectives and creating and prioritizing a portfolio of initiatives
for using the Internet in their businesses that offer our clients a variety of
ways to maximize their competitiveness in the new economic environment that has
resulted from the widespread acceptance of the Internet. After creating an
initial Internet strategy, we architect and build scalable, flexible solutions
that can be adapted over time to the evolving needs of our clients. We believe
that our strategy-led services enable new dot-coms to rapidly develop and
deploy an online business, and enable traditional businesses to redefine their
business models and leverage their existing assets.

   As of December 31, 1999, we had 312 billable professionals and during 1999
we entered into engagements with approximately 90 clients. We have offices in
Boston, New York, Pittsburgh, Chicago and San Francisco.

Industry Background

   Innovations in Internet technology and widespread acceptance of Internet-
based business models have been the primary drivers in the evolution of the
Internet economy. We believe the Internet economy has evolved in three distinct
waves as companies have increasingly realized the value of the Internet to
their businesses. Throughout these waves, companies have increasingly looked to
outside service providers to help them capitalize on the opportunities offered
by the Internet. International Data Corporation estimates that the market for
Internet services worldwide will grow from $7.8 billion in 1998 to $78.6
billion in 2003, representing a compound annual growth rate of 59%.

   First Wave. The first wave began in the early 1990s with the introduction of
the browser and the initial commercialization of the world wide web. Businesses
using the Internet in the first wave generally experimented with their websites
as marketing channels by posting static information and graphics known as
brochureware. To create these non-interactive websites, businesses generally
engaged professional service providers with graphic design skills, as the
implementation of these relatively simple websites involved limited
technological and strategic business input.

   Second Wave. The second wave began during the mid-1990s with technological
innovations that enabled the development of transaction-oriented applications
for the Internet. These applications in turn led to greater commercial
acceptance of the Internet. Taking advantage of the second wave technological
innovations, businesses have focused on building discrete Internet applications
and point solutions to enhance traditional revenue generation channels or to
effect cost reductions through supply chain efficiencies. Most of these new
applications, such as online banking, online ordering and sales force
automation, have been transaction-oriented and tailored to specific business
processes, as opposed to directed at developing a comprehensive Internet
strategy. To implement these new and more complex applications, we believe
businesses have generally engaged professional service providers with not only
website design skills but also strong technology and project management
capabilities.

   Third Wave. During the late 1990s, while some businesses continued to seek
first and second wave solutions, a third wave began as other businesses started
adopting Internet-based business models in response to the increasing number of
consumers and businesses using the Internet. According to International Data
Corporation, the number of Internet users will grow from 159 million in 1998 to
510 million in 2003, while worldwide e-commerce revenues will increase from
approximately $50 billion to more than $1.3 trillion over

                                       25
<PAGE>


the same period. We believe the difference between the projected 220% increase
in Internet users and the projected 2,500% increase in e-commerce revenues
reflects the "network effect." According to the network effect, as the Internet
matures and users proliferate, there is the potential for an exponential
increase in e-commerce revenue.

   The network effect has enabled entrepreneurial dot-com companies, such as
Amazon.com, to develop new Internet-based business models that have
fundamentally changed the economics of entire industries. In response to these
changes in industry economics, many traditional businesses are adopting
Internet-based business models or otherwise developing Internet strategies that
build on their existing assets to compete more effectively.

   Third Wave Internet Professional Service Providers. We believe that third
wave Internet service providers must have the following skills:

  .  the strategy skills to identify and prioritize a portfolio of Internet
     initiatives;

  .  the branding and user experience capabilities to distinguish a business
     from its competitors and to provide a compelling online customer
     experience;

  .  the technological skills to build and integrate complex, flexible and
     scalable applications that incorporate cutting-edge technologies; and

  .  large-scale program management skills.

   We believe that many Internet professional service providers do not offer
their customers a full range of strategy-led services. We further believe these
service providers often create solutions that are reactive to the client's
immediate business needs, rather than driven by the client's overall business
strategy. As a result, in our view these service providers end up implementing
discrete business applications and point solutions instead of strategy-based
scalable and adaptable business solutions. We believe that these service
providers are less apt to understand the broader business strategy of the
customer and, therefore, are less likely to be in a position to continually
reevaluate an initial solution.

   In addition, we believe traditional information technology service providers
often lack the integrated and multidisciplinary business strategy, experience
design, technology and program management skills required in the third wave or
they compartmentalize their competencies throughout client engagements. As a
result, multiple service providers or multiple departments within the service
provider participate in developing and implementing a solution, which causes
time delays and poorly integrated solutions. Many traditional IT service
providers also fail to establish the type of ongoing post-implementation
relationship with their clients that enables the clients to take immediate
advantage of Internet opportunities as they arise and evolve.

The ZEFER Approach

   We formed our business for the express purpose of delivering strategy-led
Internet professional services to help companies compete successfully in the
third wave Internet economy. The key elements of our service offering are as
follows:

   Strategy-led. We believe that our strategy-led approach is critical to
helping our clients develop and implement successful Internet strategies to
achieve a competitive advantage. This strategy-led approach includes:

  .  analyzing the client's industry, business model and goals;

  .  developing a portfolio of Internet initiatives in the context of an
     overall business strategy; and

  .  developing and launching various Internet initiatives in a sequence that
     maximizes business value over the long term.

                                       26
<PAGE>

   We involve our Internet strategists not only at the beginning of an
engagement, but during each phase of the project and even after initial
deployment. This allows us to continually improve the client solution by
reexamining strategic decisions in light of evolving markets and technologies.

   Integrated and Multidisciplinary. We deliver our strategy-led service
offering through integrated, multidisciplinary teams of consultants with
backgrounds in business strategy, experience design, technology and program
management. These professionals bring skills in diverse areas, including dot-
com and traditional management consulting, digital branding and cognitive
engineering, and systems integration, customer relationship management and
Internet security. We define cognitive engineering, as applied to the Internet,
to be the process of making a website intuitive and easy to use.

   This collaborative approach allows us to provide two key client benefits.
First, we believe that we are able to deliver higher quality Internet
initiatives because each discipline provides insight into the ultimate solution
during all phases of the project. Second, by staffing the engagement with a
multidisciplinary team, we develop and implement Internet initiatives without
the time delays and increased costs associated with handing off a project from
one team to another or among multiple service providers at the beginning and
end of discrete phases of a project.

   Innovative. Our commitment to research and innovation allows us to provide
our clients with Internet professional services that are at the forefront of
Internet technologies and experience design. Our consultants are trained in the
latest practices and technologies in their disciplines, and many of them are
experts in their fields. For example, one of our research and innovation
projects led to our developing an Internet application that is able to deliver
location-specific information by taking advantage of the ability to identify
the geographic location of a user accessing the web through a cellular phone-
enabled browser. During the period from our inception through December 31,
1999, we spent $1.8 million on research and innovation. We spent nothing on
research and innovation during 1997 and 1998.

   Adaptive. There are no permanent answers in the nascent and rapidly changing
Internet economy. Accordingly, we architect and build scalable, flexible
solutions that can be adapted over time in response to the client's changing
needs, technological innovations and consumer and business trends. This
adaptive approach also promotes long-term client relationships during which we
continue to generate and prioritize initiatives that address the dynamic and
ever-changing business landscape created by the Internet.

The ZEFER Strategy

   Our objective is to become the leading provider of strategy-led Internet
professional services. Our business strategy for achieving this objective is as
follows:

   Attract and Retain Outstanding Professionals. We believe that attracting and
retaining outstanding professionals is essential to our growth and the delivery
of high quality solutions to our clients. During the last nine months of 1999,
we hired an average of approximately 20 billable professionals per month. The
key elements of our hiring and retention program are as follows:

  .  Culture. We have a culture of collaboration, innovation and commitment
     in an open work environment. We offer professionals the opportunity to
     work with talented people in a variety of disciplines, which enhances
     each professional's understanding of his or her own area of
     concentration as well as the specialties of others.

  .  Training and Development. We have a comprehensive learning and
     development program that focuses on professional and personal
     development. This program includes the establishment of mentor
     relationships with peers and senior professionals and a formal skills-
     based curriculum. In addition, we are constructing a new innovation and
     training center that we expect to complete by the second quarter of
     2000.

                                       27
<PAGE>

  .  Compensation. We pay competitive salaries, grant stock options to all
     employees, award annual performance bonuses and authorize managers to
     award cash and in-kind bonuses at any time for exemplary performance.

   Serve Cutting-edge Dot-com Clients. We plan to continue to perform a
significant portion of our engagements for dot-com clients, some of which we
expect will become the leading businesses of the future. We believe that our
traditional clients value the experience that we gain from working with dot-com
clients. We also increase our internal intellectual capital by working with our
dot-com clients, which often are on the cutting edge of strategic and
technological innovations in the Internet arena. In addition, a strong client
base of dot-com businesses allows us to attract and retain talented
professionals who are eager to work with the latest technologies and business
models.

   Enhance and Extend our Integrated Service Offering. We are continually
enhancing our integrated service offering through our research and innovation
efforts. These efforts are intended to ensure that our consultants are not only
trained in the latest Internet technologies and practices, but are at the
forefront in the development of new technologies and practices. In addition, we
are extending our service offering by hiring personnel with additional skills.
For example, during 1999 we added customer relationship management, or CRM,
capabilities. Our CRM consultants specialize in automating and integrating
customer management solutions to enable our clients to find, serve and retain
customers.

   Further Develop Expertise in Targeted Industries. We are building our
expertise in serving selected key industries. We believe that this increased
expertise will enhance our ability to rapidly create solutions that are
tailored to the particular requirements of different industries. The key
industries that we have targeted are financial services, healthcare and
pharmaceuticals, technology, consumer packaged goods and retail, and media and
entertainment. We are focusing our efforts on these industries because we
believe that businesses in these industries are rapidly adopting Internet
business strategies in the third wave Internet economy.

   Build the ZEFER Brand. We are building the ZEFER brand to establish our
presence in the competitive market for Internet professional services. We have
established a strategic marketing campaign to advertise and promote our
Internet service offering in newspapers, magazines and other media. We have
also conducted executive seminars with The Wall Street Journal Interactive and
are engaged in a direct mail campaign targeting executives of both dot-com
companies and traditional businesses. In addition, we have implemented a public
relations program consisting of media relations development, publication of
articles and participation in industry events and other speaking engagements.

   Expand Alliances. We have selectively established alliances with software
and hardware vendors, including BroadVision, Microsoft, Siebel, Sun
Microsystems and Vantive. These relationships provide us with a range of
benefits, including access to the latest versions of technology developed by
our collaborators, training programs for our employees and new sales leads, co-
marketing opportunities and channels of distribution for our services. We
intend to enhance our existing alliances and establish additional alliances
with vendors that can offer us leading technologies and valuable marketing
opportunities.

The ZEFER Delivery Model

   Our delivery model is based upon a proprietary methodology that we call
ENABLE. We use ENABLE to assist our clients in choosing and implementing
successful Internet strategies. Our ENABLE methodology is designed to ensure
that we:

  .  involve professionals from all of our competencies in each phase of our
     engagements;

  .  take advantage of the standards, benchmarks and approaches that we have
     developed so that we can deliver solutions in a rapid, repeatable and
     efficient manner; and

                                       28
<PAGE>

  .  follow detailed control procedures that are designed to ensure that we
     are delivering high quality solutions.

   ENABLE consists of four phases that we refer to as ENvision, Architect,
Build and Launch, and Evolve.

   ENvision. In the ENvision phase, we explore the client's business from the
perspective of its various constituencies, including its customers, employees,
vendors and other stakeholders. We determine the business models that
competitors could pursue and design appropriate countermeasures. We also
consider the impact of emerging technologies and identify existing assets of
the client that are relevant to its Internet strategy.

   After creating a portfolio of Internet initiatives for our clients, we work
with them to prioritize these initiatives on the basis of both quantitative
and qualitative metrics. These metrics include organizational readiness, value
creation potential, complexity of implementation and resource requirements. We
believe prioritization of Internet initiatives enables our clients to maximize
the value of their Internet strategy by pursuing their initiatives in a
logical sequence. We further believe that this prioritization is essential to
the development of a long-term business strategy that will enable the client
to respond quickly and cost effectively in the evolving Internet economy.

   Architect. In the Architect phase, we start to implement the client
strategy by preparing a blueprint to guide the construction of a new Internet
business model or solution. We begin by designing functional workflows for the
Internet solution and creating application-level structural and technical
design. We provide the client with a clear understanding of how the Internet
strategy will work, the resources needed to implement and manage the strategy
and the time required to launch the new business model or solution. We
specifically design technology architectures to be highly scalable, secure and
flexible so that solutions may ultimately extend to new devices and
technologies.

   Build and Launch. In the Build and Launch phase, we implement the Internet
solution or new business model. Our services in the Build portion of this
phase include application development, systems integration, quality assurance
testing, soft launches and beta testing. Our services in the Launch portion of
this phase include development of marketing activities, design and creation of
customer service and technical support infrastructures, implementation of
training programs, and establishment of tracking mechanisms to evaluate
performance of the Internet solution or new business model.

   Evolve. Following the Build and Launch phase, a client's success will
depend, in part, upon its ability to continually adapt its business model to
the changing requirements of the Internet economy. To help them succeed, our
methodology includes a post-Build and Launch phase that we call Evolve. In the
Evolve phase, we reexamine the prioritization of the Internet initiatives
developed during the ENvision phase, evaluate knowledge gained from the
Architect and Build and Launch phases of the engagement and examine the
applicability to the client of knowledge that we have developed in other
client engagements. We believe that the Evolve phase is central to fostering
long-term client relationships.

ZEFER Competencies

   Our ENABLE delivery model integrates our competencies in the following four
areas:

   Business Strategy. Our business strategy consultants have backgrounds in
both Internet and management consulting. We believe that this combination
brings our clients fresh perspectives as well as seasoned industry expertise.
These consultants develop strategies on an iterative basis with our clients to
address the full spectrum of the client's business strategy. They identify
initiatives for the client's Internet business model, position the business in
existing and new markets and establish financial metrics to measure the
success of the model.

                                      29
<PAGE>

   Experience Design. Our experience design consultants have backgrounds in
visual design, cognitive engineering, structural design and website
architecture. These skillsets enable our consultants to design Internet
solutions that provide compelling user experiences while accomplishing the
business objectives of our clients.

   Technology. Our team of technology experts is experienced at developing and
integrating complex Internet applications. These professionals include
technical architects, programmers, integration specialists, security experts
and planning and testing experts. Our technology consultants have expertise in
the latest Internet technologies, including programming languages such as EJB,
XML and Microsoft DCOM. They also have significant experience in integrating
Internet applications with existing computing architectures.

   Program Management. Our program management professionals bring skills in the
management of large, complex client projects to our client engagements. These
professionals possess expertise in requirements management, project planning
and tracking, communications, configuration management, change management and
risk management. As the scale of Internet projects in the third wave increases,
project managers play an increasingly important role in the rapid delivery of
high quality solutions.

Representative Client Engagements

   The following case studies describe client engagements during 1999 that were
representative of the range of strategy-led Internet professional services that
we provide to our clients. The client engagements described below represent an
aggregate of 21% of our revenues for the period from our inception to December
31, 1999, with average revenues per engagement of approximately $887,000.

                          Publicaciones Semana is a Colombian publisher of
                          multiple information and entertainment magazines.

[LOGO OF SEMANA.COM]

   Semana engaged us to help them analyze the fundamental business
ramifications of taking an information-based company online. The Internet
represents both an opportunity and a challenge to print-based publishing firms
such as Semana as the publishing industry becomes increasingly electronically
based. Other key aspects of this engagement included the need to address the
low level of penetration of the Internet in Latin America and to understand
local culture.

   We developed a portfolio of strategic options for Semana after conducting a
comprehensive analysis to understand the needs of the end user and a detailed
process diagnosis to see where Semana could streamline or eliminate production
steps. For Semana's core media properties, we recommended and implemented a
comprehensive editorial process by which edits can be made via the web. This
editorial process is linked to Semana's internal computer systems such that the
transition from the old system to the new is seamless. We concurrently
identified an opportunity to take advantage of the Semana brand in new areas of
Internet business, including the introduction of the online magazine,
Semana.com. We also worked with Semana to acquire, build and extend a portal
search engine business based in Colombia, LaCiudad.com.

   We worked with Semana to launch LaCiudad.com and Semana.com in 20 weeks. We
are now working with Semana to further enhance the sites' capabilities and
begin a strategy to build a portfolio of Latin American Internet properties.

                     foodline.com is a privately held telephone and online
                     restaurant guide and reservation network.

[LOGO OF FOODLINE]

   foodline.com engaged us in early 1999 to assist it in developing its
Internet business. foodline's objective was to build on its existing electronic
restaurant guide by adding an online restaurant reservation system.

                                       30
<PAGE>


   We began this engagement by conducting a strategic study and analysis of
foodline's Internet vision and business model with the goal of helping it to
rapidly deploy a technically scalable and robust solution. We addressed the
strategic components and technical underpinnings that foodline's reservation
site would need, including a business model with multiple revenue streams, a
scalable information architecture and open technology requirements.

   We worked with foodline to develop and implement a solution that permits end
users to log onto foodline.com to research dining options according to their
preferences and seating availability. This application also confirms
reservation times online. Credit card processing is incorporated into the site
to guarantee reservations.

   The scalable nature of this solution has allowed foodline to quickly expand
to new cities. After initial implementation in Boston, foodline introduced the
solution to New York, San Francisco and Philadelphia with relatively little
incremental cost. Anthony K. Tjan, our Executive Vice President and a member of
our board of directors, sits on the board of advisors of foodline. Mr. Tjan is

                      The Children's Place is a specialty retailer of high
                      quality, value-priced apparel and accessories for
                      children with over 280 stores in the United States.
[LOGO OF THE CHILDREN'S PLACE]

   In July 1999, The Children's Place approached us with a twofold objective:
(1) create an overarching Internet vision and strategy and (2) develop and
launch the company's first e-commerce initiative, childrensplace.com, in time
for the holiday buying season. We began the engagement with an intensive
strategic planning and blueprinting phase in which we developed a staged e-
commerce strategy that would allow for a first phase launch in 16 weeks.

   In the first phase launch, we integrated several vendor applications and a
technical architecture that we custom designed for The Children's Place. These
applications include such features as a mix-and-match capability that allows
the user to construct outfits, a magnifying feature that rolls a view enhancer
over the clothes and a gift registry, Additionally, the site uses dHTML
technology, which allows for enhanced functionality without any additional
applications, thereby keeping the site easy to use.

   Childrensplace.com enabled The Children's Place to reach a new customer base
outside of its traditional store-based customers in the eastern United States.
The site has received positive customer feedback and recently was featured on a
national television news program.

   After the initial launch, we collaborated with The Children's Place to
change the site's look and feel to reflect the upcoming spring 2000 transition
fashion line. Because we had designed the site to be scalable and adaptive, we
were able to implement the release of an entirely refreshed site only weeks
after the initial launch. Part of the longer-term Internet strategy that we
have developed with The Children's Place is to evolve childrensplace.com into a
destination site for children.

                      Zuellig Pharma is a healthcare product distributor and
                      healthcare information delivery company in the Asia
                      Pacific region. Zuellig Pharma provides exclusive
                      distribution and information-based services for the
                      largest pharmaceutical manufacturers in the world and to
                      leading hospitals, pharmacies and clinics in 22 Asian
                      countries.

   Zuellig Pharma engaged us to develop an Internet-based strategy to secure
its position in the market and provide a foundation for future Internet
initiatives. We helped Zuellig Pharma define a strategy to better service

                                       31
<PAGE>


its suppliers by providing real-time access to sales and supply chain
information about the thousands of products Zuellig Pharma distributes in the
region. In just 16 weeks, we designed a system that allows Zuellig Pharma's
internal computer network to tie into the internal computer networks of its
suppliers over the Internet. This type of system is called an "extranet."

   We helped design Zuellig Pharma's business-to-business extranet with the
technical architecture needed to support a complex structure. The technical
architecture supports integration with back-end systems to provide a scalable
platform for future initiatives. The web site functionality permits a faster
flow of information to users by incorporating a mechanism for analyzing data in
a secure fashion. This model provides increased flexibility and functionality
by allowing users access to various levels of online tools and catalog views
based on their security level.

   The site delivers a combination of real-time and historical sales
information to both the pharmaceutical manufacturers that supply Zuellig Pharma
and the company's sales teams and country managers. The site is designed with
multicurrency and multilingual functionality to accommodate Zuellig Pharma's
multinational operations.

                                    retailer.


[LOGO OF GREENLIGHT.COM/TM/]

   Greenlight.com engaged us to assist it in building a dot-com business that
would use the Internet to transform the entire car buying experience, from
model selection to delivery.

   In just 10 weeks, we developed Greenlight.com's website in such a way as to
provide a premier customer car buying experience while maintaining a
technological infrastructure able to adapt to the aggressive growth targets
established by Greenlight.com. We designed a personalized area called My
Showroom that allows users to compare specific models in which they are
interested. My Showroom saves that information so that users may return to
check on price updates or to edit the vehicle configuration. In addition to
creating Greenlight's consumer website, we also developed a comprehensive
system to help account managers track customer orders, manage dealer
relationships, create vehicle options packages and edit pricing. We continue to
work with Greenlight.com to refine its business model and the functionality of
the site.

Sales and Marketing

   Our marketing strategy is to build the ZEFER brand in order to solidify our
presence in the competitive market for Internet professional services. Our
strategic marketing programs include advertising in major publications, direct
mailings, Internet campaigns, speaking engagements and other sponsored
marketing events, including executive seminars with The Wall Street Journal
Interactive. We have also retained an outside public relations and advertising
firm to assist us with our marketing efforts.

   Our direct field marketing and sales organization sells and promotes our
services to both dot-com and traditional businesses. In addition, our senior
consultants and members of our management, many of whom are well recognized in
the Internet and strategic consulting industries, frequently participate in
establishing contacts with potential clients and securing client engagements.
Many of our sales leads are also generated by our marketing initiatives or are
the result of referrals from the parties with whom we have alliances.

Clients

   During the period from inception (March 18, 1999) through December 31, 1999,
we derived approximately 69% of our revenues from services performed for
traditional businesses and approximately 31% from dot-com businesses. Most of
our clients are located in the United States, although we have performed
engagements for international clients. Our clients listed below are
representative of the range of strategy-led Internet professional services that
we provide:

Knowledge Management

   Our knowledge management system, which we call ZEFER 360(degrees), is a
comprehensive, integrated infrastructure that encompasses the Internet, our
internal intranet and extranets with clients and parties with whom we have
alliances. ZEFER 360(degrees) affords our employees, clients and vendors
customized access to our research, knowledge, expertise and tools.

   ZEFER 360(degrees) improves productivity by:

  . supporting knowledge capture and transfer;

  . promoting experience sharing by accumulating and storing knowledge gained
    from past and current projects, internal and external databases and
    contact information from consultants with specific expertise;

  . facilitating training with resource materials, handouts and training
    sessions that can be carried live for remote users; and

  . facilitating internal and external relationship building and innovation.

   We have a dedicated knowledge management team to support and continually
develop ZEFER 360(degrees).

Talent, Career Development and Culture

   Talent. We dedicate significant resources to identifying and recruiting
students from top educational institutions and professionals from other
businesses. Our corporate human resources staff focuses on executive,
managerial, business and technical recruiting, as well as college and MBA
recruiting, to identify professionals with the background and experience
required to provide our service offerings. Our corporate staff in turn supports
dedicated regional recruiters who manage the local recruiting process.

   We hold onsite evening recruiting events, called "Z nights," on a regular
basis to allow candidates to experience our culture and to meet future co-
workers. We have established relationships with selected search firms, agencies
and contract recruiters who supplement our in-house recruiting efforts.
Approximately one-third of our employees are referred to us by existing
employees, whom we reward with cash incentives and special prizes.

   Career Development. We believe that challenging work and continuing
education are critical to retaining talented employees. All new employees
participate in the ZEFER Acceleration Program, which is an intensive, week-long
orientation program that provides experience in our culture, values, management
practices and philosophy. We also regularly offer professional development
courses and a formal skills-based curriculum. We are constructing a 12,000
square foot innovation and training center in Boston. We expect to complete
this center by the second quarter of 2000.

   Culture. We work in multi-disciplinary teams and support a culturally and
demographically diverse workplace. We respect individual expression, freedom of
thought and action. While we are passionate about our

                                       33
<PAGE>

work, we value the other components of our lives and respect personal and
professional balance. We are committed to exceeding the expectations of our
clients and ourselves through the quality of our work, our focus on client
service and our investment in the professional development of our people.

Competition

   We compete in the new and emerging Internet professional services market.
This market is highly competitive. Many of our competitors have longer
operating histories, better name recognition, larger client bases and greater
financial, technical, marketing and public relations resources than we. Because
the Internet professional services market has relatively low barriers to entry,
we believe competition will intensify as the market evolves.

   Our principal competitors include:

  .  Internet-focused professional service firms, such as Proxicom,
     Razorfish, Scient and Viant;

  .  strategic management consulting companies, such as Booz-Allen &
     Hamilton, Boston Consulting Group, Andersen Consulting and McKinsey &
     Company;

  .  traditional IT service and systems integration firms, such as the Big
     Five accounting firms, Cambridge Technology Partners, Computer Sciences
     Corporation, IBM and Sapient; and

  .  internal IT departments of our prospective clients.

   We believe that the key competitive factors are integrated and
multidisciplinary business strategy, experience design and technology skills,
company reputation for Internet expertise, strategic insight and implementation
excellence, strategic project management and large-scale program management
capabilities and an ability to provide services in a timely and cost-effective
manner. We believe that we compete successfully with respect to each of these
competitive factors.

Proprietary Rights

   We have developed processes, skillsets, technologies, software and
methodologies, including our ENABLE methodology, that we consider to be
proprietary. We have tried to protect our proprietary rights through reliance
on a combination of trade secret, copyright and trademark laws. In particular,
we require our employees to sign a confidentiality and invention assignment
agreement upon employment with us which provides that they must maintain the
confidentiality of our intellectual property and that any intellectual property
that they create while employed by us belongs to us.

   We are in the process of registering the trademark "ZEFER" with the United
States Patent and Trademark Office. We intend to make such other state and
federal filings as we believe are appropriate to protect our intellectual
property rights.

Employees

   As of December 31, 1999, we had a total of 481 employees, including 312
billable employees in our competencies of business strategy, experience design,
technology and program management. None of our employees is represented by a
labor union. We consider our employee relations to be good.

Facilities

   Our principal executive offices are located in an 18,600 square foot leased
facility in Boston, Massachusetts. The lease for this facility expires in
August 2004. We also lease an additional 70,800 square feet of office space in
Boston. The leases of this additional space expire at various times through
December 2005. We also lease an aggregate of 142,600 square feet of office
space in Chicago, New York, Pittsburgh and San Francisco. We believe that our
facilities are satisfactory for our current needs.

Legal Proceedings

   From time to time we may be involved in litigation that arises in the normal
course of business operations. As of the date of this prospectus, we are not
involved in any material litigation.

Executive Officers

office until his successor is elected and qualified or until his earlier
resignation or removal. There are no family relationships among any of our
directors or executive officers.

Election of Directors

   The board of directors is divided into three classes, each of whose members

McAdam and Rauner serve in the class whose term expires in 2002 and Messrs.

three-year term to succeed the directors of the same class whose terms are then
expiring.

   The employment agreement that we entered into with Mr. Tjan on April 30,
1999 provides that we shall cause Mr. Tjan to be elected as a director of our
company. The stockholders agreement discussed in "Certain Transactions" below
provides that, until the consummation of this offering, each party to that
agreement will vote all shares of our capital stock held by such party to elect
the following persons to our board of directors: Mr. Seibel and one of our
executives designated by the chief executive officer, two representatives of
GTCR and three independent persons chosen jointly by GTCR and the chief
executive officer.

Compensation of Directors

of the board of directors or its committees that they attend to reimburse them
for their expenses incurred. Upon his election to the board in June 1999, Mr.
Nolan received a nonstatutory stock option to purchase 30,000 shares of common

exercise price of $11.00 per share, vest over a four-year period in equal
annual installments. All directors are eligible to receive additional grants of
options under our stock incentive plans.

Board Committees

   Our board of directors has an audit committee and a compensation committee.
The audit committee consists of Messrs. Jabbar, McAdam and Nolan. The audit
committee makes recommendations to the board of directors regarding the
selection of independent accountants, reviews the results and scope of the
audit and other services provided by our independent accountants and reviews
and evaluates our audit and control functions. The compensation committee
consists of Messrs. Canfield and Lubin and Ms. Johnston. The compensation
committee administers our stock plans and makes decisions concerning salaries
and incentive compensation for our employees.

Benefit Plans

   1999 Stock Incentive Plan. Our 1999 Stock Incentive Plan was adopted by our
board of directors and approved by our stockholders in June 1999. In February
2000, our board of directors approved an amendment to our incentive plan
increasing the shares available for issuance under the plan to 22,666,666.

   This incentive plan provides for the grant of options intended to qualify as
incentive stock options, or ISOs, under Section 422 of the Internal Revenue
Code, nonstatutory stock options, restricted stock awards and other stock and
non-stock based awards.

   Officers, employees and other persons who provide services to us are
eligible to receive awards under the this incentive plan. No participant may
receive any award for more than 1,000,000 shares in any calendar year.

   Optionees receive the right to purchase a specified number of shares of
common stock at a specified option price and subject to such other terms and
conditions as are specified in connection with the option grant. The board of
directors or an appointed committee may grant options at an exercise price less
than, equal to or greater than the fair market value of our common stock on the
date of grant, which in no event may be less than the par value of the
underlying stock.

   The board of directors has directed the compensation committee to administer
this incentive plan. The board of directors has the authority to adopt, amend
and repeal the administrative rules, guidelines and practices relating to the
plan and to interpret its provisions. Subject to any applicable limitations
contained in this incentive plan, the compensation committee:

  .  determines eligibility for and selects the recipients of awards;

                                       38
<PAGE>

  .  determines, modifies and waives the terms and conditions of any award;

  .  prescribes forms, rules and procedures, which it may modify or waive;

  .  interprets the plan; and

  .  otherwise does all things necessary to carry out the purposes of the
     plan.

   In the event of mergers, liquidations or other acquisition events described
in the plan, our board of directors may do any or all of the following:

  .  cause any or all outstanding awards to be exercisable;

  .  vest all awards;

  .  accelerate all deferrals;

  .  make a cash payment to settle the award; or

  .  provide for the assumption or substitution of all awards with that of
     the acquiring or surviving entity.

   No ISOs may be granted under this incentive plan after May 21, 2009, but the
vesting and effectiveness of ISOs previously granted may extend beyond that
date. The compensation committee may at any time amend, suspend or terminate
this incentive plan, except that no such amendment will, without the approval
of our stockholders, effectuate a change for which stockholder approval is
required in order for this incentive plan to continue to qualify under Section
422 of the Internal Revenue Code and for awards to be eligible for the
performance-based exception under Section 162(m) of the Internal Revenue Code.

   1999 Stock Option Plan. Our 1999 Stock Option Plan was adopted by our board
of directors and approved by our stockholders in June 1999. Up to 2,000,000
shares of common stock, subject to adjustment in the event of stock splits and
other similar events, may be issued pursuant to awards granted under this
option plan. Employees, consultants and advisers of businesses that we acquire
are eligible to receive nonstatutory stock options under this option plan.

   Optionees receive the right to purchase a specified number of shares of
common stock at a specified option price and subject to such other terms and
conditions as are specified in connection with the option grant. The board of
directors or an appointed committee may grant options at an exercise price less
than, equal to or greater than the fair market value of our common stock on the
date of grant, which in no event may be less than the par value of the
underlying stock.

   The board of directors has directed the compensation committee to administer
this option plan. The board of directors has the authority to adopt, amend and
repeal the administrative rules, guidelines and practices relating to the plan
and to interpret its provisions. Subject to any applicable limitations
contained in this option plan, this compensation committee:

  .  selects the recipients of options;

  .  determines the number of shares of stock subject to each option;

  .  determines the terms and conditions of each option;

  .  adopts, amends and rescinds rules and regulations for the administration
     of the plan; and

  .  interprets the plan, decides any questions and settles all controversies
     and disputes that may arise in connection with the plan.

   In the event of a merger, liquidation or other acquisition event, our board
of directors may do any or all of the following:

  .  cause any or all outstanding options to be exercisable immediately prior
     to the consummation of such transaction;

                                       39
<PAGE>

  .  make a cash payment to settle the option; or

  .  provide for the assumption or substitution of all options by the
     acquiring or surviving entity.

   No award may be granted under this option plan after June 2009, but the
vesting and effectiveness of options previously granted may extend beyond that
date. Our board of directors may at any time amend, suspend or terminate the
option plan.

   2000 Employee Stock Purchase Plan. Our 2000 Employee Stock Purchase Plan was
adopted by our board of directors and approved by our stockholders in February
2000. The purchase plan authorizes the issuance of up to a total of 500,000
shares of our common stock to participating employees.

   Employees who are customarily employed for more than 30 hours per week and
for more than five months per year, including our directors who are employees
and employees of any participating subsidiaries, are eligible to participate in
the purchase plan.


   Employees who would immediately after the grant own 5% or more of the total
combined voting power or value of our stock or any subsidiary are not eligible
to participate. As of December 31, 1999, approximately 480 of our employees
would have been eligible to participate in the purchase plan.

   On the first day of a designated payroll deduction period, or "offering
period," we will grant to each eligible employee who has elected to participate
in the purchase plan an option to purchase shares of our common stock as
follows: the employee may authorize between 1% to 10% of his or her base pay to
be deducted by us from his or her base pay during the offering period. On the
last day of the offering period, the employee is deemed to have exercised the
option, at the option exercise price, to the extent of accumulated payroll
deductions. Under the terms of the purchase plan, the option price is an amount
equal to 85% of the per share closing price of our common stock on either the
first day or the last day of the offering period, whichever is lower. In no
event may an employee purchase under the purchase plan in any year a number of
shares which exceeds the number of shares determined by dividing $25,000 by the
average market price of a share of common stock on the commencement date of the
offering period.

   The first offering period under the purchase plan will be one year long. The
board of directors will choose the timing and length of subsequent offering
periods.

   An employee who is not a participant on the last day of the offering period
is not entitled to exercise any option and the employee's accumulated payroll
deductions will be refunded. An employee's rights under the purchase plan
terminate upon voluntary withdrawal from the purchase plan at any time, or when
the employee ceases employment for any reason.

   401(K) Plan. In June 1999, we adopted an employee savings and retirement
plan qualified under Section 401 of the Internal Revenue Code and covering all
of our employees. Pursuant to the 401(k) plan, employees may elect to reduce
their current compensation by up to the statutorily prescribed annual limit and
have the amount of such reduction contributed to the 401(k) plan.

Senior Management Agreements

   William A. Seibel. On March 23, 1999, we entered into a senior management
agreement with Mr. Seibel which provides for his employment as President and
Chief Executive Officer. Under the terms of this agreement, Mr. Seibel's
employment will continue until he resigns or we terminate his employment.
Mr. Seibel's initial base salary was $325,000 per year and was increased to
$375,000 per year in October 1999. Mr. Seibel is eligible to receive an annual
performance bonus of up to 50% of his base salary. The board of

                                       40
<PAGE>


directors may increase Mr. Seibel's base salary in its discretion based upon
our achievement of specified objectives. Mr. Seibel received a one-time special
bonus of $80,000 when he joined us. We also provide Mr. Seibel with medical
insurance benefits, a $2,000,000 term life insurance policy and other benefits
generally made available to our senior management.

   Mr. Seibel's senior management agreement contains provisions requiring him
to protect the confidentiality of our proprietary and confidential information.
In addition, Mr. Seibel is prohibited during the term of his employment and for
a period of two years after from competing with us, soliciting any of our
employees or interfering with any of our business relationships. If Mr.
Seibel's employment is terminated by us without cause or by him for good
reason, he will be entitled to receive his base salary and medical insurance
benefits as severance for a period of two years thereafter.

   In connection with the execution of his senior management agreement, Mr.
Seibel purchased 3,040,000 shares of restricted common stock from us on March
23, 1999, for which he paid a total of $380,000, $1,900 in cash and $378,100 in
the form of a recourse promissory note. Mr. Seibel's senior management
agreement provides us with rights to purchase all of his restricted stock if
his employment with us terminates for any reason. If we do not exercise our
purchase right, some of the other members of our management team have the right
to purchase these shares. These purchase rights will terminate upon the
consummation of this offering with respect to stock that has vested on the date
that the purchase right is triggered. Mr. Seibel's restricted stock vests 20%
per year, with the first vesting date occurring on March 23, 2000, so as to
vest in full on March 23, 2004. Upon consummation of this offering, this stock
will continue to vest at the same rate, but on a quarterly basis. Mr. Seibel's
stock will vest in full in the event of a change in control or sale of our
company. The purchase price for Mr. Seibel's vested shares is the fair market
value of the stock on the date of repurchase. The purchase price for Mr.
Seibel's unvested shares is the original purchase price paid by Mr. Seibel.

   The promissory note issued by Mr. Seibel to purchase the restricted stock
bears interest at a rate of 5% per year, compounded annually, and is not
repayable until the fifth anniversary of the date the note was issued, at which
time it is repayable in full as to both principal and accrued interest. Mr.
Seibel must make prepayments on the note when we raise additional equity
funding from GTCR. In the event Mr. Seibel receives any cash dividend on the
restricted stock or proceeds from the sale of the restricted stock, such
proceeds must be applied to principal outstanding and unpaid accrued interest
on his notes. In the event of the sale of our company, Mr. Seibel must repay
the entire principal amount then outstanding and all accrued interest on his
note. We have the right to offset any amounts owed to us by Mr. Seibel against
any amounts payable to him by us pursuant to his senior management agreement.

                                       41

   Other Senior Executive Officers. We have also entered into senior management
agreements with the other named executive officers. These senior management
agreements and the associated restricted stock arrangements are substantially
similar to those of Mr. Seibel, except that these agreements:

  .  did not provide for a signing bonus or the $2,000,000 life insurance
     policy;

  .  provide that the rights of repurchase will terminate only upon changes
     in control described in these agreements;

  .  establish March 31, 2000 as the first vesting date, so that the
     restricted stock will be fully vested on March 31, 2004; and

  .  prohibit the executive from competing with us, soliciting any of our
     employees or interfering with any of our business relationships for a
     period of one year after the termination of employment, which period is
     reduced to six months if the executive's employment is terminated
     without cause within two years of a change in control of our company.

   Additional differences are described below.

   Under a senior management agreement entered with us on August 19, 1999, Mr.
Dube receives a base salary of $300,000 per year, is eligible to receive an
annual performance bonus of up to 66.67% of base salary, has a severance period
of six months, and purchased 800,000 shares of restricted common stock for
which he paid $21,400 in cash and $80,600 in the form of a recourse promissory
note. The period of Mr. Dube's noncompetition, nonsolicitation and
noninterference covenant is six months.

   Under a senior management agreement entered with us on May 21, 1999, Mr.
Mullaney receives a base salary of $165,000 per year, is eligible to receive an
annual performance bonus of up to 35% of base salary, has a severance period of
six months, and purchased 420,000 shares of restricted common stock for which
he paid $4,600 in cash and $47,900 in the form of a recourse promissory note.
Additionally, Mr. Mullaney is entitled to receive a bonus of $50,000 in 2000.

Slamp receives a base salary of $175,000 per year, is eligible to receive an
annual performance bonus of up to 35% of base salary, has a severance period of
six months, and purchased 400,000 shares of restricted common stock for which
he paid $27,200 in cash and $74,800 in the form of a recourse promissory note.
We also provided Mr. Slamp with a one-time special moving expense reimbursement
of $70,800 when he joined us.

   Under a senior management agreement entered with us on May 21, 1999, Ms.
Stephens began to receive a base salary of $170,000 per year in May 1999, which
was increased to $200,000 per year in October 1999. Ms. Stephens is eligible to
receive an annual performance bonus of up to 35% of base salary, has a
severance period of six months, and purchased 420,000 shares of restricted
common stock for which she paid $4,600 in cash and $47,900 in the form of a
recourse promissory note.

   Under an employment agreement entered with us on April 30, 1999, Mr. Tjan
began to receive a base salary of $165,000 per year in May 1999, which was
increased to $190,000 in October 1999. Mr. Tjan is eligible to receive an
annual performance bonus of up to 35% of base salary and has a severance period
of two years. The period of Mr. Tjan's noncompetition, nonsolicitation and
noninterference covenant is one year. In addition, Mr. Tjan received 844,800
shares of restricted common stock from us in connection with a Section 351
reorganization of Original ZEFER for the purpose of continuing the business of
Original ZEFER, and therefore did not execute a promissory note in connection
with his acquisition of these shares. We have the right to repurchase only Mr.
Tjan's shares of restricted stock that have not vested. Mr. Tjan's restricted
stock vests as to 20% of the shares on the first anniversary of April 30, 1999,
40% on the second anniversary, 70% on the third anniversary and will be fully
vested on the fourth anniversary. If Mr. Tjan terminates his employment
voluntarily, the repurchase price will be $0.125 per share, the fair market
value of the shares on April 30, 1999. In the event that Mr. Tjan is terminated
by us without cause, the repurchase price will be the fair market value of such
shares as of the date of termination. See "Certain Transactions--Original
ZEFER."

was increased to $200,000 per year in October 1999. Mr. Torbey is eligible to
receive an annual performance bonus of up to 35% of base salary, has a
severance period of six months, and purchased 440,000 shares of restricted
common stock for which he paid $4,800 in cash and $50,200 in the form of a
recourse promissory note.

Mr. Waite receives a base salary of $225,000 per year, is eligible to receive
an annual performance bonus of up to 35% of base salary and has a severance
period of six months. The period of Mr. Waite's noncompetition, nonsolicitation
and noninterference covenant is six months. In addition, Mr. Waite received
263,200 shares of restricted common stock from us in connection with our
acquisition of Waite & Company, and therefore did not execute a promissory note
in connection with his acquisition of these shares. We have the right to
repurchase only Mr. Waite's shares of restricted stock that have not vested at
a price equal to $0.75 per share, the fair market value of the shares on
September 13, 1999. Mr. Waite's restricted stock vests as to 30% on the first
anniversary of March 31, 1999, 60% on the second anniversary, 73% on the third

                              CERTAIN TRANSACTIONS

GTCR Golder Rauner, L.L.C.

   Prior to this offering, funds controlled by GTCR Golder Rauner, L.L.C., or
the "GTCR Funds," beneficially own 66.8% of our common stock and 97.5% of our
class A preferred stock. All of the class A preferred stock held by the GTCR
Funds will be exchanged into common stock or redeemed in connection with this
offering. After this offering, the GTCR Funds will beneficially own 63.5% of
our common stock. Two of our directors, Messrs. Canfield and Rauner, are
principals of GTCR, and Mr. McAdam is a Vice President of GTCR.

   Securities Purchase Agreement. On March 23, 1999, we entered into a
securities purchase agreement with the GTCR Funds pursuant to which the GTCR
Funds agreed to provide our company with up to $65.3 million in cash equity
financing. Pursuant to this agreement, as of December 31, 1999, the GTCR Funds
had purchased an aggregate of 26,640,000 shares of our common stock for a
purchase price of $3.3 million and an aggregate of 24,195 shares of our class A
preferred stock for a purchase price of $24.2 million. Under the terms of the
agreement, all future sales of equity to the GTCR Funds must be in the form of
class A preferred stock at a purchase price of $1,000 per share. We and GTCR
have agreed that upon the completion of this offering, we will terminate this
agreement and we will exchange shares of our common stock for all of GTCR's
class A preferred stock, including related accrued and unpaid dividends. This
exchange rate is based on an assumed initial public offering price of $12.00
per share. For additional information about the exchange of the class A
preferred stock, please refer to "Redemption of Class A Preferred Stock" below.

   Loan Agreement. On November 24, 1999, we entered into a loan agreement with
GTCR Capital Partners, LP, an affiliate of GTCR. The loan agreement provides
for up to $32.2 million of borrowings by us, of which we borrowed $12.8 million
on November 24, 1999 to fund operations. It is currently anticipated that we
will incur an additional $9.1 million of indebtedness during the first quarter
of 2000. Borrowings under this loan will remain outstanding after the
consummation of this offering, but we will not be making additional borrowings
under this loan after the consummation of this offering. Borrowings under this
loan agreement bear interest at 12% per annum and are secured by substantially
all of our assets. Interest is payable quarterly in arrears, with our first
payment having been made for the quarter ended December 31, 1999. As of March
1, 2000, approximately $296,000 in unpaid interest will have accrued under the
loan. In the event that the net proceeds of this offering exceed $42.8 million,
we will apply the first such additional net proceeds to repay the outstanding
subordinated indebtedness under this loan agreement. See "Use of Proceeds."

   Concurrently with the execution of the loan agreement, we repurchased from
the GTCR Funds 1,650,450 shares of common stock for an aggregate price of
$206,300 and 1,499 shares of class A preferred stock for an aggregate price of
$1,499,000. We also issued GTCR Capital Partners, LP, the lender, a warrant to
purchase 1,650,450 shares of common stock and a warrant to purchase 1,499
shares of class A preferred stock, each at a purchase price of $0.01 per share.
GTCR Capital Partners, LP exercised both warrants in full in November 1999 for
an aggregate purchase price of $16,500. Additionally, we agreed to issue GTCR
Capital Partners, LP warrants to purchase up to an additional 4,720 shares of
class A preferred stock as we make additional borrowings under the loan
agreement.

   Guarantee. GTCR has also guaranteed all of our borrowings under a $20.0
million line of credit with Harris Bank and Trust Company. We intend to repay
the outstanding borrowings under the Harris Bank line with net proceeds of this
offering and the guarantee will be terminated. See "Management's Discussion and
Analysis of Historical Financial Condition and Results of Operations--Liquidity
and Capital Resources."

   Professional Services Agreement. On March 23, 1999, we entered into a
professional services agreement with GTCR pursuant to which GTCR provides us
with financial and management consulting services. We pay GTCR an annual
management fee of $150,000 for these services, payable in equal monthly
installments, upon the achievement of financial targets set forth in the
agreement that have not been met. In the event we engage in any equity or debt
financing, other than this offering and the other GTCR financing arrangements,
we must pay GTCR a placement fee equal to 1% of the aggregate gross proceeds of
such financing. This agreement will terminate upon the consummation of this
offering.

$0.125 per share. The stock vests 20% per year, with the first vesting date
occurring on March 31, 2000, so as to vest in full on March 31, 2004. Upon
consummation of this offering, this stock will continue to vest at the same
rate, but on a quarterly basis. Mr. Lubin's stock will vest in full in the
event of a change in control or sale of our company.

   The above investments are in addition to the restricted stock purchases
described under "Management--Senior Management Agreements." All of the above
shares of stock are fully vested. All of the above purchases were financed by
interest free loans made by us to the executives, which have been paid in full.

Redemption of Class A Preferred Stock

   Upon the consummation of this offering, all of the holders of our class A
preferred stock have agreed with us to exchange all shares of class A preferred
stock held by them, including related accrued and unpaid

                                       45
<PAGE>


dividends, for that number of shares of common stock determined by dividing the
class A preferred liquidation value by the initial public offering price. An
aggregate of 47,198 shares of class A preferred stock would be exchanged for an
aggregate of 3,933,166 shares of common stock, based on an assumed initial
public offering price of $12 per share and a liquidation value for all class A
preferred stock, including accrued and unpaid dividends, of $1,520,988 as of
December 31, 1999. In the event that the net proceeds to us of this offering
exceed $42.8 million and after we have repaid in full the outstanding
indebtedness under the GTCR loan, we will apply the additional net proceeds
received by us to redeem on a pro rata basis shares of common stock that are
received by the holders of class A common stock in connection with the exchange
at a price per share equal to the initial public offering price. The holders of
such common stock must surrender their shares for redemption in this event.

Original ZEFER

   In April 1999, we consummated a reorganization under Section 351 of the
Internal Revenue Code for the purpose of continuing the business of Original
ZEFER. The stockholders of Original ZEFER received an aggregate of $7,100,000
in cash and 3,456,000 shares of common stock in connection with the
reorganization. Anthony K. Tjan, our Executive Vice President and one of our
directors, was the President and Chief Executive Officer and a principal
stockholder of Original ZEFER. Mr. Tjan received $2.4 million in cash and
844,800 shares of our restricted common stock in connection with the
transaction. Concurrently, Mr. Tjan was elected to our board of directors. The
shares of common stock issued to Mr. Tjan are subject to our right, which
expires incrementally over a four-year period, to repurchase these shares if
Mr. Tjan ceases to be employed by us. Additionally, Mr. Tjan has agreed to a
noncompetition, nonsolicitation and noninterference covenant of two years from
the closing of the reorganization. For more information on our rights to
repurchase these shares, please see the description of Mr. Tjan's senior
management agreement under "Management--Senior Management Agreements" above.

Waite & Company

   In September 1999, we acquired Waite & Company, Inc., a Boston,
Massachusetts-based strategic marketing and management consulting firm. The
stockholders of Waite & Company, Inc. received an aggregate of $8,034,100 in
cash and 1,200,000 shares of common stock in connection with the acquisition.
Thomas J. Waite, our Executive Vice President of Business Strategy and
Strategic Marketing, was the President and a principal shareholder of Waite &
Company, Inc. Mr. Waite received $5.3 million in cash and 263,200 shares of our
restricted common stock in connection with the transaction. The shares issued
to Mr. Waite are subject to our right, which expires incrementally over a five-
year period, to purchase these shares at a price equal to their fair market
value at the time of the acquisition if Mr. Waite ceases to be employed by us.
Additionally, Mr. Waite has agreed to a noncompetition, nonsolicitation and
noninterference covenant of one year from the closing of that transaction, and
has agreed that in the event of the termination of his employment with us, he
will not perform work for our customers for a period of eighteen months from
the closing of the acquisition. For more information on our right to purchase
these shares, please see the description of Mr. Waite's senior management
agreement under "Management--Senior Management Agreements" above.

   The acquisition prices of the above entities were determined by arms' length
negotiation.

                          DESCRIPTION OF CAPITAL STOCK

   After this offering, our authorized capital stock will consist of
150,000,000 shares of common stock, $.001 par value per share and 5,000,000
shares of preferred stock, $0.01 par value per share, all of which remain
undesignated. After giving effect to this offering, we will have outstanding
47,995,767 shares of common stock.

   The following description reflects the filing, immediately upon the closing
of this offering, of our amended and restated certificate of incorporation and
the adoption of our amended and restated by-laws.

Common Stock

   Holders of common stock are entitled to one vote for each share held on all
matters submitted to a vote of stockholders and do not have cumulative voting
rights. Accordingly, holders of a majority of the shares of common stock
entitled to vote in any election of directors may elect all of the directors
standing for election. Holders of common stock are entitled to receive
proportionately any dividends as may be declared by our board of directors,
subject to any preferential dividend rights of outstanding preferred stock.
Upon our liquidation, dissolution or winding up, the holders of common stock
are entitled to receive proportionately our net assets available after the
payment of all debts and other liabilities and subject to the prior rights of
any outstanding preferred stock. Holders of common stock have no preemptive,
subscription, redemption or conversion rights. Our outstanding shares of common
stock are and the shares offered by us in this offering will be, when issued
and paid for, fully paid and nonassessable. The rights, preferences and
privileges of holders of common stock are subject to and may be adversely
affected by, the rights of the holders of shares of any series of preferred
stock which we may designate and issue in the future.

Undesignated Preferred Stock

   Under the terms of our certificate of incorporation, our board of directors
is authorized to issue shares of preferred stock in one or more series without
stockholder approval. Our board of directors has the discretion to determine
the rights, preferences, privileges and restrictions, including voting rights,
dividend rights, conversion rights, redemption privileges and liquidation
preferences, of each series of preferred stock.

   The purpose of authorizing our board of directors to issue preferred stock
and determine its rights and preferences is to eliminate delays associated with
a stockholder vote on specific issuances. The issuance of preferred stock,
while providing desirable flexibility in connection with possible acquisitions
and other corporate purposes, could have the effect of making it more difficult
for a third party to acquire, or could discourage a third party from seeking to
acquire, a majority of our outstanding voting stock. We have no present plans
to issue any shares of preferred stock.

Delaware Law and Charter and By-Law Provisions

   We are subject to the provisions of Section 203 of the General Corporation
Law of Delaware. Section 203 prohibits a publicly held Delaware corporation
from engaging in a "business combination" with an "interested stockholder" for
a period of three years after the person became an interested stockholder,
unless the business combination is approved in a prescribed manner. A "business
combination" includes mergers, asset sales and other transactions resulting in
a financial benefit to the interested stockholder. In general, an "interested
stockholder" is a person who, together with affiliates and associates, owns, or
within the prior three years did own, 15% or more of the corporation's voting
stock.

   Our certificate of incorporation divides our board of directors into three
classes with staggered three-year terms. In addition, our certificate of
incorporation provides that directors may be removed only for cause by the

                                       49
<PAGE>

affirmative vote of the holders of a majority of our shares of capital stock
entitled to vote. Under our certificate of incorporation, any vacancy on our
board of directors, including a vacancy resulting from an enlargement of our
board of directors, may only be filled by vote of a majority of our directors
then in office. The classification of our board of directors and the
limitations on the removal of directors and filling of vacancies could make it
more difficult for a third party to acquire, or discourage a third party from
seeking to acquire, control of our company. See "Management."

   Our by-laws provide that stockholders must follow an advance notification
procedure for stockholder nominations of candidates for the board of directors
and for other stockholder business to be conducted at stockholder meetings. Our
by-laws further provide that special meetings of the stockholders may only be
called by our Chairman of the Board, President or the board of directors. These
provisions could have the effect of delaying until the next stockholder meeting
stockholder actions which are favored by the holders of a majority of our
outstanding voting securities.

   The General Corporation Law of Delaware 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 by-laws,
unless a corporation's certificate of incorporation or by-laws, as the case may
be, requires a greater percentage. Our certificate of incorporation and by-laws
require the affirmative vote of the holders of at least two-thirds of the
shares of our capital stock issued and outstanding and entitled to vote to
amend or repeal any of the provisions described in the prior two paragraphs.

   Our certificate of incorporation contains provisions permitted under the
General Corporation Law of Delaware relating to the liability of directors. The
provisions eliminate a director's liability for monetary damages for a breach
of fiduciary duty, except in limited circumstances involving wrongful acts,
such as the breach of a director's duty of loyalty or acts or omissions that
involve intentional misconduct or a knowing violation of law. Further, our
certificate of incorporation contains provisions to indemnify our directors and
officers to the fullest extent permitted by the General Corporation Law of
Delaware. We believe that these provisions will assist us in attracting and
retaining qualified individuals to serve as directors.

Transfer Agent and Registrar

   The transfer agent and registrar for our common stock is      .

                        SHARES ELIGIBLE FOR FUTURE SALE

   Before this offering, there has been no public market for our securities.
After we complete this offering, there will be 47,995,767 shares of our common
stock outstanding, assuming no exercise of outstanding options or warrants to
purchase common stock. Of these outstanding shares, the 4,000,000 shares sold
in this offering will be freely tradeable without restriction or further
registration under the Securities Act of 1933, except that any shares purchased
by our "affiliates," as that term is defined in Rule 144 under the Securities
Act, may generally only be sold in compliance with the limitations of Rule 144
described below.

Sales of Restricted Shares

   The remaining 43,995,767 shares of common stock outstanding after this
offering are deemed "restricted securities" under Rule 144. Of these
securities,

  .  4,571,761 shares may be sold 90 days after the effective date of this
     offering; and

  .  33,832,246 additional shares may be sold upon expiration of the 180-day
     lock-up agreements described below.

   All of our existing stockholders have agreed that, for a period of 180 days
after the date of this prospectus, they will not dispose of any shares of our
common stock, or any shares convertible into or exchangeable for shares of our
common stock, without the prior written consent of Credit Suisse First Boston
Corporation, acting on behalf of the representatives of the underwriters.
However, the GTCR Funds will be released from these lock-up restrictions as to
4,571,761 shares of common stock 90 days after the date of this prospectus.

   In general, under Rule 144 a stockholder, including one of our affiliates,
who has beneficially owned his or her restricted securities 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% of the then outstanding shares of our common stock or the average
weekly trading volume in our common stock during the four calendar weeks
preceding the date on which notice of such sale was filed under Rule 144,
provided requirements concerning availability of public information, manner of
sale and notice of sale are satisfied. In addition, a stockholder that is not
one of our affiliates at any time during the three months preceding a sale and
who has beneficially owned the shares proposed to be sold for at least two
years is entitled to sell the shares immediately under Rule 144(k) without
compliance with the above described requirements under Rule 144.

   Securities issued in reliance on Rule 701, such as shares of our common
stock acquired pursuant to the exercise of certain options granted under our
stock plans, are also restricted securities. Beginning 90 days after the date
of this prospectus, but subject to the 180-day lock-up agreement described
above, Rule 701 securities may be sold by stockholders other than our
affiliates subject only to the manner of sale provisions of Rule 144 and by
affiliates under Rule 144 without compliance with its one-year holding period
requirement.

Stock Options

   We intend to file registration statements on Form S-8 under the Securities
Act to register an aggregate of 25,166,666 shares of common stock issuable
under the incentive plan, the option plan and the purchase plan promptly
following the date of this prospectus. Shares issued upon the exercise of stock
options after the effective date of the Form S-8 registration statements will
be eligible for resale in the public market without restriction, subject to
Rule 144 limitations applicable to affiliates and lock-up restrictions.

Registration Rights

   After this offering, the holders of approximately 40,000,000 shares of
common stock will be entitled to rights with respect to the registration of
those shares under the Securities Act of 1933. Under the terms of the agreement
between us and the holders of those registrable shares, the holders of a
majority of those shares may

                                       51
<PAGE>


at any time require us to file a registration statement under the Securities
Act with respect to shares of common stock owned by them having an aggregate
offering price of at least $5.0 million and we are required to use our
reasonable best efforts to effect that registration. Also, if we propose to
register any of our securities under the Securities Act, other than demand
registrations, registrations on Form S-8 or in connection with our initial
public offering, those holders are entitled to notice of and to include shares
of common stock in the registration. All of these registration rights are
subject to various conditions and limitations, among them rights of the
underwriters of an offering to limit the number of shares included in a
registration and our right not to effect a requested registration within 90
days after the effective date of a previous registration on a Form S-1 or
within 90 days after the effective date of a registration which included all
shares requested by holders of registrable shares. We will bear all of the
expenses incurred in connection with all exercises of these registration
rights.

Effect of Sales of Shares

   Prior to this offering, there has been no public market for our common stock
and no prediction can be made as to the effect, if any, that market sales of
shares of common stock or the availability of shares for sale will have on the
market price of our common stock prevailing from time to time. Nevertheless,
sales of significant numbers of shares of our common stock in the public market
could adversely affect the market price of the common stock and could impair
our future ability to raise capital through an offering of our equity
securities.

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

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

  .  a citizen or individual resident of the United States;

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

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

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

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

   This discussion does not address all aspects of United States federal income
and estate taxes that may be relevant to non-U.S. holders in light of their
personal circumstances, including the fact that in the case of a non-U.S.
holder that is a partnership, the U.S. tax consequences of holding and
disposing of shares of common stock may be affected by determinations made at
the partner level, or that may be relevant to non-U.S. holders which may be
subject to special treatment under United States federal income tax laws such
as insurance companies, tax-exempt organizations, financial institutions,
dealers in securities and holders of securities held as part of a "straddle,"
"hedge" or "conversion transaction." This discussion also does not address U.S.
state or local or foreign tax consequences. Furthermore, this discussion is
based on provisions of the Internal Revenue Code of 1986, existing and proposed
regulations promulgated thereunder and administrative and judicial
interpretations thereof, all as of the date hereof, and all of which are
subject to change, possibly with retroactive effect. The following summary is
included herein for general information. Accordingly, investors are urged to
consult their tax advisers regarding the United States federal, state, local
and non-U.S. income and other tax consequences of acquiring, holding and
disposing of shares of common stock.

Dividends

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

   Dividends that are effectively connected with a non-U.S. holder's conduct of
a trade or business in the United States or, if an income tax treaty applies,
attributable to a permanent establishment in the United States, are generally
subject to U.S. federal income tax on a net income basis at regular graduated
rates, but are not generally subject to the 30% withholding tax if the non-U.S.
holder complies with applicable certification and disclosure requirements. Any
such U.S. trade or business income received by a non-U.S. holder that is a
corporation may also be subject to an additional "branch profits tax" at a 30%
rate or such lower rate as may be specified by an applicable income tax treaty.

                                       53
<PAGE>

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

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

   The U.S. Treasury regulations generally effective for payments made after
December 31, 2000 also provide special rules for dividend payments made to
foreign intermediaries, U.S. or foreign wholly owned entities that are
disregarded for U.S. federal income tax purposes and entities that are treated
as fiscally transparent in the United States, the applicable income tax treaty
jurisdiction, or both. In addition, in specified circumstances, income tax
benefits may be denied to non-U.S. holders receiving income derived through a
partnership, or otherwise fiscally transparent entity.

Gain on Disposition of Common Stock

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

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

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

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

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

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


                                       54
<PAGE>


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

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

Federal Estate Tax

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

Information Reporting and Backup Withholding Tax

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

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

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

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

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

   The payment of the proceeds of the disposition of our common stock by a
holder to or through the U.S. office of a broker or through a non-U.S. branch
of a U.S. broker generally will be subject to information reporting and backup
withholding at a rate of 31% unless the holder either certifies its status as a
non-U.S. holder under penalties of perjury or otherwise establishes an
exemption. The payment of the proceeds of the disposition by a non-U.S. holder
of common stock to or through a non-U.S. office of a non-U.S. broker will not
be subject to backup withholding or information reporting unless the non-U.S.
broker has particular types of U.S. relationships. In the case of the payment
of proceeds from the disposition of our common stock effected by a foreign
office of a broker that is a U.S. person or a U.S. related person, existing
regulations require

                                       55
<PAGE>

information reporting on the payment unless the broker receives a statement
from the owner, signed under penalty of perjury, certifying its non-U.S. status
or the broker has documentary evidence in its files as to the non-U.S. holder's
foreign status and the broker has no actual knowledge to the contrary. For this
purpose, a U.S. related person is defined as:

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

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

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

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

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

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

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

                                  UNDERWRITING

   Under the terms and subject to the conditions contained in an underwriting
agreement dated        2000, we have agreed to sell to the underwriters named
below, for whom Credit Suisse First Boston Corporation, First Union Securities,
Inc. and FleetBoston Robertson Stephens Inc. are acting as representatives, the
following respective numbers of shares of our common stock:

</TABLE>

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

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

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

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

   The underwriters have informed us that they do not expect discretionary
sales to exceed 5% of the common stock being offered.

                                       57
<PAGE>


   We, our officers and directors and all of our existing stockholders have
agreed not to dispose of any additional shares of our common stock or
securities convertible into or exchangeable or exercisable for any of our
common stock without the prior written consent of Credit Suisse First Boston
Corporation for a period of 180 days after the date of this prospectus,
provided that the GTCR Funds will be released from these lock-up restrictions
as to 4,571,761 shares of common stock 90 days after the date of this
prospectus. However, we may issue shares of common stock pursuant to the
exercise of employee stock options, employee stock purchases pursuant to the
terms of any existing plan or the issuance of shares pursuant to the exercise
of any outstanding warrants.

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

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

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

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

  .  the information included in this prospectus and otherwise available to
     the representatives;

  .  market conditions for initial public offerings;

  .  the history and the prospects for the industry in which we will compete;

  .  the ability of our management;

  .  our prospects for future earnings;

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

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

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

   The initial offering price may not correspond to the price at which our
common stock will trade in the public market subsequent to this offering, and
an active trading market for our common stock may not develop or continue after
this offering.

   The representatives may engage in over-allotment, stabilizing transactions,
syndicate covering transactions and penalty bids in accordance with Regulation
M under the Securities Exchange Act of 1934.

  .  Over-allotment involves syndicate sales in excess of the offering size,
     which creates a syndicate short position.

  .  Stabilizing transactions permit bids to purchase the underlying security
     so long as the stabilizing bids do not exceed a specified maximum.

  .  Syndicate covering transactions involve purchases of the common stock in
     the open market after the distribution has been completed in order to
     cover syndicate short positions.

  .  Penalty bids permit the representatives to reclaim a selling concession
     from a syndicate member when the shares of common stock originally sold
     by such syndicate member are purchased in a stabilizing transaction or a
     syndicate covering transaction to cover syndicate short positions.

                                       58
<PAGE>

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

                          NOTICE TO CANADIAN RESIDENTS

Resale Restrictions

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

Representation of Purchasers

   Each purchaser of common stock in Canada who receives a purchase
confirmation will be deemed to represent to us and the dealer from whom such
purchase confirmation is received that (1) such purchaser is entitled under
applicable provincial securities laws to purchase such common stock without the
benefit of a prospectus qualified under such securities laws; (2) where
required by law, that such purchaser is purchasing as principal and not as
agent; and (3) such purchaser has reviewed the text above under "Resale
Restrictions."

Rights of Action (Ontario Purchasers)

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

Enforcement of Legal Rights

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

Notice to British Columbia Residents

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

Taxation and Eligibility for Investment

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

                 REPORTS OF INDEPENDENT PUBLIC ACCOUNTANTS

To ZEFER Corp.:

   We have audited the accompanying balance sheet of ZEFER Corp. (a Delaware
Corporation) as of December 31, 1999, and the related statements of operations,
redeemable preferred stock and stockholders' deficit and cash flows for the
period from inception (March 18, 1999) through December 31, 1999. 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 auditing standards generally
accepted in the United States. 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 ZEFER Corp. as of December
31, 1999, and the results of its operations and its cash flows for the period
from inception (March 18, 1999) through December 31, 1999, in conformity with
accounting principles generally accepted in the United States.

To ZEFER Corp.:

   We have audited the accompanying balance sheets of ZEFER Corp. (a Delaware
Corporation herein referred to as Original ZEFER) as of December 31, 1998 and
April 30, 1999, and the related statements of operations, redeemable
convertible preferred stock and stockholders' deficit and cash flows for the
period from inception (March 19, 1998) through December 31, 1998 and for the
four months ended April 30, 1999. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on the financial statements based on our audits.

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

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of ZEFER Corp. as of December
31, 1998 and April 30, 1999, and the results of its operations and its cash
flows for the period from inception (March 19, 1998) through December 31, 1998
and for the four months ended April 30, 1999, in conformity with accounting
principles generally accepted in the United States.

                         NOTES TO FINANCIAL STATEMENTS

                             December 31, 1999

(1) The Company and Summary of Significant Accounting Policies

   ZEFER Corp. (the Company) was incorporated in Delaware on March 18, 1999 and
is an Internet consulting and implementation firm. Since its inception, the
Company has grown its business principally through certain strategic
acquisitions (see Note 4).

   The accompanying financial statements include the financial statements of a
predecessor company also named ZEFER Corp. (Original ZEFER). The Company was
formed for the purpose of continuing the business of Original ZEFER, which was
incorporated in Delaware on March 19, 1998 as an Internet professional services
firm. On April 30, 1999, the Company effected a reorganization whereby all of
the outstanding capital stock of Original ZEFER was exchanged for 3,456,000
shares of Company common stock valued at $432,000 and $7.1 million in cash. In
accordance with Accounting Principles Board (APB) Opinion No. 16, Accounting
for Business Combinations, this transaction has been accounted for using the
purchase method of accounting (see Note 4). For purposes of continuity of
operations, the accompanying financial statements include the results of
operations of Original ZEFER from inception (March 19, 1998) through the date
of its reorganization (April 30, 1999) and the results of operations of the
Company from inception (March 18, 1999) through December 31, 1999. The results
of operations of the Company for the period from inception (March 18, 1999)
through April 30, 1999 were not significant.

   The Company is subject to risks common to rapidly growing, technology
companies, including limited operating history, integration of acquisitions,
dependence on key personnel, rapid technological change, competition from
substitute services and larger companies, and the need for continued market
acceptance of the Company's services.

   The accompanying financial statements reflect the application of the
accounting policies as described below and elsewhere in these notes to
financial statements. Unless otherwise noted, references in these notes to
financial statements of the Company relate to both the Company and Original
ZEFER.

   (a) 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 reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

   (b) Revenue Recognition--Revenue is derived from professional service
agreements. Due to the significant production and customization element of our
professional service arrangements, we recognize revenue in accordance with
Accounting Research Bulletin No. 45, Long-term Construction-type Contracts,
using the relevant guidance in Statement of Position (SOP) No. 81-1, Accounting
for Performance of Construction-type and Certain Production-type Contracts.
Revenues pursuant to time and materials contracts are generally recognized as
services are performed. Revenues pursuant to fixed-fee contracts are generally
recognized as services are rendered and are determined based on the percentage-
of-completion method of accounting (based on the ratio of costs incurred to
total estimated project costs). Contracts generally extend over a three-to-six-
month period. The cumulative impact of any revisions in estimates of the
percent complete is reflected in the period in which the changes become known.
Revenues exclude reimbursable expenses charged to and collected from clients.

   Provisions for estimated losses on uncompleted contracts are made on a
contract-by-contract basis and are recognized in the period in which such
losses become probable and can be reasonably estimated. As of December 31,
1999, the Company had a provision for estimated losses of approximately
$374,000 related to uncompleted contracts.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

                             December 31, 1999

   (c) Cost of Revenues--Cost of revenues consists primarily of compensation
and benefits of employees engaged in the delivery of professional services and
non-reimbursable expenses related to client projects.

   (d) Cash and Cash Equivalents--All highly liquid investments purchased with
an original maturity of 90 days or less are considered to be cash equivalents.
The Company invests excess cash primarily in money market accounts, U.S.
Treasury securities, certificates of deposit and short-term commercial paper
which are subject to minimal credit and market risks.

   (e) Unbilled Receivables and Deferred Revenue--Unbilled accounts receivable
represent amounts recognized as revenue in advance of the scheduled billing for
such services. Billings received in advance of services are classified as
deferred revenue.

   (f) Concentration of Credit Risk and Significant Customers--Financial
instruments that potentially subject the Company to a concentration of credit
risk consist of cash and cash equivalents and accounts receivable. Cash and
cash equivalents are deposited with high-credit quality financial institutions.
The Company's accounts receivable are derived from revenue earned from clients
located predominantly in the United States. The Company performs ongoing credit
evaluations of its clients' financial condition and maintains reserves for
potential credit losses based on the expected collectibility of total accounts
receivable. To date, the Company has not experienced any material credit
losses.

   For the period from inception through December 31, 1999, the Company did not
have any one customer who accounted for greater than 10% of total revenues. For
the period from inception through December 31, 1998, the Company recorded
revenues from three customers who individually represented 58%, 19% and 11% of
total revenues. For the four months ended April 30, 1999, the Company recorded
revenues from four customers who individually represented 30%, 20%, 17% and 15%
of total revenues.


   At December 31, 1999, the Company did not have any one customer who
represented greater than 10% of total accounts receivable. At December 31,
1998, the Company had accounts receivable from four customers who individually
represented 44%, 22%, 14% and 12% of total accounts receivable. At April 30,
1999, the Company had accounts receivable from four customers who individually
represented 28%, 26%, 23% and 16% of total accounts receivable.

   (g) Prepaids and Other Current Assets--Prepaid expenses and other current
assets consist of prepaid rent, recruiting costs, contract costs and employee
receivables at December 31, 1999.

   (h) Fair Value of Financial Instruments--The financial instruments of the
Company, including cash and cash equivalents, accounts receivable, accounts
payable, line-of-credit obligations, notes payable and subordinated debt are
carried at cost, which approximates their fair value because of the short-term
nature of these instruments.

   (i) Property and Equipment--Property and equipment are stated at cost less
accumulated depreciation. The Company provides for depreciation and
amortization by charges to operations using the straight-line method, which
allocates the cost of property and equipment over their estimated useful lives
of two to three years for computer equipment and software, three to five years
for furniture and fixtures and the life of the related lease for equipment
under capital lease and leasehold improvements.

   (j) Goodwill and Other Intangible Assets, Net--Goodwill and other intangible
assets associated with acquisitions (see Note 4) and with the reorganization of
Original ZEFER (see Note 1) consist of the following at December 31, 1999:

                                                                     22,501,000
      Less--Accumulated amortization...............................   6,718,361
                                                                    -----------
                                                                    $15,782,639
                                                                    ===========
</TABLE>

   (k) Long-Lived Assets--The Company reviews its long-lived assets, including
goodwill and other intangible assets, for impairment as changes in events and
circumstances indicate the carrying amount of an asset may not be recoverable.
In assessing whether there has been an impairment of goodwill and other
intangible assets, the Company first reviews several qualitative factors
related to the acquired businesses, including turnover of the acquired
workforce and a comparison of budgeted revenues versus actual revenues of the
acquired businesses. If the Company's assessment of these qualitative factors
indicates the possibility of an impairment, the Company measures such
impairment using the undiscounted future cash flows of the related asset or
group of assets. If the sum of the undiscounted future cash flows is less than
the carrying amount of the asset or group of assets, the Company will recognize
an impairment loss equal to the excess carrying amount. Based upon the review
of qualitative factors, management believes that, as of December 31, 1999, none
of the Company's long-lived assets have been impaired.

   (l) Other Long-term Assets--Other long-term assets consist of security
deposits for the Company's facilities at December 31, 1999.

   (m) Stock Compensation--The Company accounts for employee stock compensation
arrangements in accordance with provisions of APB Opinion No. 25, Accounting
for Stock Issued to Employees, and complies with the disclosure provisions of
Statement of Financial Accounting Standards (SFAS) No. 123, Accounting for
Stock-Based Compensation. Under APB Opinion No. 25, compensation expense is
based on the difference, if any, on the date of grant between the fair value of
the stock and the exercise price.

   (n) Income Taxes--The Company accounts for income taxes in accordance with
SFAS No. 109, Accounting for Income Taxes, which requires the recognition of
taxes payable or refundable for the current year and deferred tax liabilities
and assets for the future tax consequences of events that have been recognized
in the financial statements or tax returns. The measurement of current and
deferred tax liabilities and assets is based on provisions of the enacted tax
law; the effects of future changes in tax laws or rates are not anticipated.

   (o) Net Loss per Share--In accordance with SFAS No. 128, Earnings per Share,
basic and diluted net loss per share is computed by dividing the net loss
available to common stockholders for the period by the weighted average number
of shares of common stock outstanding during the period. The calculation of
basic and diluted weighted average shares outstanding for the period from
inception through December 31, 1999 excludes 9,314,467 shares of unvested
restricted common stock issued to management and in connection with

                             December 31, 1999

acquisitions (see Note 11(d)). For periods in which a net loss has been
incurred, the calculation of diluted net loss per share excludes potential
common stock as their effect is antidilutive. Potential common stock is
composed of (i) incremental shares of common stock issuable upon the exercise
of stock options and warrants and upon the exchange or conversion of preferred
stock and (ii) unvested restricted common stock subject to repurchase by the
Company. For the period from inception through December 31, 1999, the
calculation of diluted weighted average shares outstanding excludes the
following potential common stock:

                                                                      13,941,578
                                                                      ==========
</TABLE>

   In accordance with the Securities and Exchange Commission's Staff Accounting
Bulletin No. 98, Earnings per Share in an Initial Public Offering, the Company
determined that there were no nominal issuances of common stock prior to the
Company's initial public offering (IPO).

   (p) Software Development Costs--SFAS No. 86, Accounting for the Costs of
Computer Software To Be Sold, Leased or Otherwise Marketed, requires the
capitalization of certain computer software development costs incurred after
technological feasibility is established. The Company believes that once
technological feasibility of a software product has been established, the
additional development costs incurred to bring the product to a commercially
acceptable level are not significant. To date, the Company has not incurred or
capitalized any software development costs.

   (q) Internal-Use Computer Software--In accordance with SOP 98-1, Accounting
for the Costs of Computer Software Developed or Obtained for Internal Use, the
Company capitalizes costs related to software and implementation in connection
with its internal-use software systems. As of December 31, 1999, the Company
had not capitalized any internal-use computer-software costs.

   (r) Pro Forma Net Loss per Share (Unaudited)--The Company's historical
capital structure at December 31, 1999 is not indicative of its capital
structure prior to the closing of the IPO due to the automatic exchange of all
shares of Class A redeemable convertible preferred stock into common stock
concurrent with the closing of the Company's IPO. Accordingly, pro forma net
loss per share is presented for the period from inception through December 31,
1999 assuming (i) the net loss before the accretion of preferred stock
dividends, discount and offering costs and (ii) the exchange of all outstanding
shares of redeemable convertible preferred stock into common stock using the
as-converted method from their respective dates of issuance, but excluding
shares of common stock to be issued in the IPO. A reconciliation of the
numerators and denominators used in computing historical and pro forma net loss
per share is as follows:

   (s) Comprehensive Income--Comprehensive income is defined as the change in
equity of a business enterprise during a period from transactions and other
events and circumstances from non-owner sources. The only component of
comprehensive income (loss) of the Company for the period from inception is net
loss. Therefore, comprehensive loss is the same as the reported loss for all
periods presented.

   (t) Disclosures About Segments of an Enterprise and Related Information--

   Operating segments are identified as components of an enterprise about which
separate discrete financial information is available for evaluation by the
chief operating decision maker, or decision making group, in making decisions
how to allocate resources and assess performance. The Company's chief decision
making group consists of the chief executive officer and the chief financial
officer. Based on the criteria established by SFAS No. 131, Disclosures about
Segments of an Enterprise and Related Information, the Company has one
reportable operating segment, the results of which are disclosed in the
accompanying financial statements. Substantially all of the operations and
assets of the Company have been derived from and are located in the United
States.

   Revenues by country in total and as a percentage of total revenues are as
follows for the period from inception through December 31, 1998, the four
months ended April 30, 1999 and the period from inception through December 31,

   (u) Recent Accounting Pronouncements--In June 1998, the Financial Accounting
Standards Board (FASB) issued SFAS No. 133, Accounting for Derivatives and
Hedging Activities. SFAS No. 133, as amended by SFAS No. 137, is effective for
all fiscal quarters beginning with the quarter ending September 30, 2000. SFAS
No. 133 establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts, and for hedging activities. The Company will adopt SFAS No. 133 in
its quarter ending September 30, 2000 and does not expect that such adoption to
have an impact on the Company's results of operations, financial position or
cash flows.

   (v) Stock Splits--On June 15, 1999, the Company declared a three-for-one
stock split. On November 30, 1999, the Company declared an additional four-for-
three stock split and increased the authorized number of shares of common stock
to 100,000,000. All share and per share amounts in the accompanying financial
statements and notes have been retroactively adjusted in all periods presented
to reflect these stock splits.

   (d) Allocation of Purchase Consideration--All of the 1999 acquisitions,
including the reorganization of Original ZEFER, have been accounted for using
the purchase method of accounting in accordance with APB Opinion No. 16,
Business Combinations and, accordingly, the purchase price has been allocated
to the tangible assets acquired and liabilities assumed and, with the advice of
independent valuation experts, to the identifiable intangible assets. The
results of operations of the acquired entities are included in those of the
Company beginning on the respective dates of acquisition. The Company allocated
total consideration from the 1999 acquisitions and from the reorganization of
Original ZEFER to the fair value of the assets acquired and liabilities assumed
on the dates of acquisition as follows:

</TABLE>

   The noncurrent liabilities referred to in the above table include noncurrent
portions of assumed capital lease obligations and long-term deferred tax
liabilities in the amount of $5,760,400 for the income tax effect of basis
differences on the nondeductible intangible assets (see Note 6). Assembled
workforce is being amortized over a period of 36 months; noncompetition
agreements are being amortized over periods of 12 to 24 months. The purchase
price in excess of identified tangible and intangible assets acquired and
liabilities assumed was allocated to goodwill. As a result of the early stage
of development of the Internet and electronic commerce, the dynamics of this
rapidly evolving industry and the expectation of increasing competition, the
recorded goodwill is being amortized on a straight-line basis over four years,
the estimated period of its benefit. Through December 31, 1999, the Company has
recorded accumulated amortization related to its goodwill and other intangible
assets of approximately $8,068,000.

   (e) Pro Forma Disclosures (Unaudited)--The following unaudited pro forma
consolidated amounts for the period from inception through December 31, 1999
give effect to the 1999 acquisitions and the reorganization of Original ZEFER
as if they had all occurred on the Company's date of inception (March 18,
1999), by consolidating the results of operations of the 1999 acquired entities
with the pre-acquisition results of the Company for the period from inception
through December 31, 1999. The pro forma amounts do not purport to be
indicative of the results of operations that would have been achieved had the
transactions been in effect as of the inception of the Company and should not
be construed as being representative of future results of operations.

(5) Related Party Professional Services Agreement

   Effective March 23, 1999, the Company entered into a professional services
agreement with GTCR Golder Rauner, L.L.C. (GTCR), a stockholder that owns 97.5%
of the outstanding redeemable preferred stock and 66.8% of the outstanding
common stock of the Company (see Note 11(c)) and with whom the Company has a
subordinated debt agreement (see Note 9). Under the terms of the agreement,
GTCR will provide financial and management consulting to the Company. At the
time of any equity or debt financing of the Company other than the purchase of
stock or issuance of debt by GTCR or other GTCR financings, the Company shall
pay to GTCR a placement fee equal to 1% of the gross amount of such financing
(including the committed amount of any revolving credit facility). In addition
to the placement fee, the Company shall pay GTCR an annual management fee of
$150,000, payable in equal monthly installments, provided, however, that such
management fee shall not commence until the Company determines (i) that its
earnings before interest, taxes, depreciation and amortization (EBITDA) for the
previous 30 days has been sufficient to cover the payment of such management
fee together with any increases in the annual base salary of the Company's
executives as required by such executives' respective management agreements and
(ii) that its pro forma projections for the next 12 months show that the
Company's EBITDA is likely to continue to be sufficient to cover such
management fee together with such increases in annual base salary. For the
period from inception to December 31, 1999, no amounts have been payable under
the management fee arrangement. This management fee agreement terminates upon
the consummation of an IPO and no amounts become payable upon an IPO or other
event that terminates the agreement.

(6) Income Taxes

   At December 31, 1999, the Company had approximately $26.7 million of federal
and state net operating loss carryforwards available to offset future taxable
income, which expire in varying amounts beginning in 2019. Under the Tax Reform
Act of 1986, the amounts of and benefits from net operating loss carryforwards
may be impaired or limited in certain circumstances. Events which cause
limitations in the amount of net operating losses that the Company may utilize
in any one year include, but are not limited to, a cumulative ownership change
of more than 50%, over a three-year period, as defined.

   At December 31, 1998 and April 30, 1999, Original ZEFER had net operating
loss carryforwards for federal and state income tax purposes of approximately
$555,000 and $2,208,000, respectively. These carryforwards expire through 2018
and are subject to review and possible adjustment by the Internal Revenue
Service. Upon the acquisition of Original ZEFER by the Company, Original
ZEFER's net operating loss carryforward was acquired by the Company. Under
Section 382 of the Internal Revenue Code, the amount that may be utilized by
the Company to offset future taxable income on an annual basis is limited to
approximately $400,000 per year.

   For the period from inception through December 31, 1999, the Company
incurred losses before benefit from income taxes of approximately $36.3
million, which is the primary component of the Company's deferred tax asset at
December 31, 1999. In connection with the stock acquisitions discussed in Note
4, the Company established a deferred tax liability for the income tax effect
of basis differences on the non-deductible intangible assets (exclusive of
goodwill), with a corresponding increase in goodwill. The Company has
recognized in the statement of operations the tax benefit of a portion of the
current period net operating losses as an offset to this deferred tax
liability.

(7) Lines of Credit

   (a) Unsecured Demand Line of Credit--In July 1999, the Company entered into
a $20,000,000 unsecured demand line of credit (the Demand Line) with a bank.
Borrowings on the Demand Line accrue interest at the prime lending rate (8.5%
at December 31, 1999) and interest is payable monthly. All borrowings under the
Demand Line are guaranteed by GTCR. At December 31, 1999, the Company had
$19,416,122 outstanding under the Demand Line.

   (b) Revolving Line of Credit--In December 1998, Original ZEFER obtained a
revolving line of credit facility (the Revolving Line) from a bank which
provides for borrowings up to $200,000. Borrowings were limited to 80% of
eligible accounts receivable, as defined, and bear interest at the prime
lending rate plus 0.5% and interest is payable monthly. Original ZEFER was
required to comply with certain restrictive covenants under this agreement,
including minimum levels of working capital and tangible net worth, and the
line was collateralized by all assets, as defined. The Revolving Line expires
on March 15, 2000 and all outstanding borrowings thereunder are payable on that
date. There were no borrowings outstanding under the Revolving Line at December
31, 1998 or April 30, 1999.

                               December 31, 1999

   In connection with the acquisition of Original ZEFER by the Company, the
Company assumed the Revolving Line. At December 31, 1999, the Company was not
in compliance with either of its financial covenants and was in receipt of a
waiver from the bank. At December 31, 1999, the Company had $150,000
outstanding under the Revolving Line.

   (c) Equipment Lease Line of Credit--In June 1998, Original ZEFER entered
into a $250,000 equipment lease line of credit (the Equipment Line) designated
for the acquisition of computer and office equipment. In January 1999, the
Equipment Line was amended to allow for an additional $500,000 in borrowings by
January 2000. In connection with the acquisition of Original ZEFER by the
Company, the Company assumed Original ZEFER's obligations under the Equipment
Line, as amended. Principal and interest are payable over 36 months, and
interest accrues at a rate of 11%. At December 31, 1998, April 30, 1999 and
December 31, 1999, the Company had $237,133, $288,577 and $414,536,
respectively, outstanding under the Equipment Line, which is included in
capital lease obligations in the accompanying financial statements.

(8) Notes payable

   (a) Spyplane Notes--As part of the consideration for the acquisition of
Spyplane (Note 4(a)), the Company issued to the former members of Spyplane
promissory notes in the aggregate principal amount of $980,000 (the Spyplane
Notes). The Spyplane Notes bear interest at a rate of 8% per year. One half of
the interest accruing on the Spyplane Notes is payable on May 14, 2000. Also on
May 14, 2000, the Company shall pay an aggregate of $180,000 of the outstanding
principal amount. All remaining unpaid principal and interest on the Spyplane
Notes will be payable on May 14, 2001.

   (b) Renaissance Note--As part of the consideration for the acquisitions of
the Divisions of Renaissance (Note 4(b)), the Company issued to Renaissance a
promissory note in the principal amount of $2,000,000 (the Renaissance Note).
The Renaissance Note bears interest at a rate equal to the 30-day LIBOR (5.8%
at December 31, 1999) plus 2.0% per annum and interest is payable quarterly for
the period extending from August 1999 through May 2002. Principal is payable in
eight quarterly installments commencing May 2000. The Renaissance Note is
subordinate to any senior indebtedness, as defined.

   At the option of Renaissance, the principal amount outstanding under the
Renaissance Note is convertible to common stock of the Company at a conversion
price equal to 80% of the per share price to the public of the Company's common
stock in an IPO. The Company has valued this beneficial conversion feature at
$400,000, which has been recorded as additional interest expense in the
accompanying statement of operations.

   (c) Future Maturities--Future maturities of the principal obligation under
the Spyplane and Renaissance Notes are as follows:

(9) Subordinated Debt Financing

   On November 24, 1999, the Company entered into a loan agreement with GTCR,
the majority investor in the Company. The loan agreement provides for up to
$32,196,296 of borrowings, of which the Company borrowed $12,789,175 on
November 24, 1999 to fund operations. The Company, at its discretion, may make
additional borrowings from time to time.

                             December 31, 1999

   Borrowings under the loan agreement bear interest at 12% per annum and
interest is payable quarterly in arrears beginning December 31, 1999. The loan
agreement matures on November 24, 2004. Upon a change in control, as defined,
or upon an IPO, the Company is required to repay all unpaid principal and
interest. In addition, should the Company dispose of any assets or subsidiaries
for net proceeds in excess of $100,000, the Company is required to prepay the
loans in an amount equal to such net proceeds. Borrowings are secured by
substantially all assets of the Company.

   Concurrent with the loan agreement, the Company repurchased from GTCR
1,650,405 shares of common stock at the issuance price of $0.125 per share and
1,499 shares of redeemable preferred stock at the issuance price of $1,000 per
share. Simultaneously, the Company issued to GTCR the lender, a warrant to
purchase 1,650,405 shares of common stock and a warrant to purchase 1,499
shares of redeemable preferred stock, each at an exercise price of $.001 per
share. GTCR exercised both warrants in full at the time of the transaction. The
Company has recorded the value of this beneficial exercise price (approximately
$1,705,000) as an original issuance discount on the subordinated debt financing
and has presented in the Statement of Stockholder's Deficit the net effect of
the purchase of the treasury stock and the respective sale of stock upon
exercise of the warrants, and is amortizing this discount as additional
interest expense over the term of the loan agreement. Additionally, the Company
agreed to issue GTCR warrants to purchase up to an additional 4,720 shares of
class A preferred stock as we make additional borrowings under the loan
agreement.

   Under the loan agreement, the Company must maintain compliance with certain
negative covenants and financial covenants. The negative covenants include
limits on indebtedness, certain investments, capital expenditures and lease
payments. The financial covenants are effective for the quarter ending June 30,
2000 and include a minimum required level of pre-corporate EBITDA and a minimum
required level of fixed charge coverage.

   (b) Contingencies--From time to time, the Company may have certain
contingent liabilities that arise in the ordinary course of its business
activities. The Company accrues contingent liabilities when it is probable that
future expenditures will be made and such expenditures can be reasonable
estimated. In the opinion of management, there are no pending claims of which
the outcome is expected to result in a material adverse effect in the financial
position or results of operations of the Company.

(11) Capital Stock

   (a) Redeemable Preferred Stock--As of December 31, 1999, the Company has
authorized a total of 96,632 shares of Class A redeemable preferred stock
(Class A Preferred Stock), of which 24,814 shares have been issued at a per
share price of $1,000. The Class A Preferred Stock is entitled to the following
rights and preferences:

     Redemption--The Company shall have the option to redeem, subject to
  certain conditions, all or any portion of the Class A Preferred Stock
  outstanding before an IPO or change in control, as defined. Upon the
  occurrence of an IPO, the holders of a majority of the Class A Preferred
  Stock have the option to force redemption of the Class A Preferred Stock
  with the proceeds from the offering. Upon a change in control, as defined,
  the Class A Preferred Stock is redeemable at the option of the holder.

     Dividends--The holders of Class A Preferred Stock are entitled to
  receive cumulative dividends when and if declared by the Board of Directors
  (the Board) of the Company. Dividends accrue from the date of the share
  issuance at a daily compounded rate of 8% of the liquidation value ($1,000
  per share) and are cumulative. Dividends are payable upon redemption of the
  Class A Preferred Stock or liquidation of the Company. Due to the fact that
  the Class A Preferred Stock is non-convertible, non-voting and redeemable
  at the option of the holder upon the closing of an IPO or change in
  control, the 8% dividend has been recorded as interest expense rather than
  a reduction of stockholders' equity in the accompanying financial
  statements.

     Voting Rights--Except under certain defined conditions and otherwise
  required by applicable law, the Class A preferred stockholders shall have
  no voting rights, provided that each holder of Class A Preferred Stock
  shall be entitled to notice of all stockholders meetings.

     Liquidation--In the event of any voluntary or involuntary liquidation,
  dissolution or winding up of the Company, as defined, the holders of the
  Class A Preferred Stock then outstanding will be entitled to $1,000 per
  share plus all dividends that have accrued and any other dividends declared
  but unpaid. Amounts remaining after payment to the Class A preferred
  stockholders, if any, will be shared among all stockholders.

   (b) Common Stock--The Company's Certificate of Incorporation, as amended,
authorizes the Company to issue up to 100,000,000 shares of $.001 par value
common stock. A portion of the shares issued are subject to the right of
repurchase by the Company at the original purchase price prior to vesting,
which generally occurs over a period of four to five years from the issuance
date until vesting is complete (see Note 11(d)).

   (c) GTCR Investment--On March 23, 1999, the Company entered into a stock
purchase agreement with GTCR, as amended whereby GTCR would provide up to
$97,500,000 in equity financing to fund acquisitions and internal growth (the
GTCR Investment). The equity to be issued to GTCR is a combination of common
stock and Class A Preferred Stock. On November 24, 1999 this agreement was
amended to provide up to $65.3 million in cash equity financing and $32.2
million of subordinated debt (see Note 9). The Company is not required to
issue, and GTCR is not required to purchase, all of the shares of common and
preferred stock contemplated in the stock purchase agreement.

                             December 31, 1999

Under the agreement, upon the approval of the Board and at the request of GTCR,
GTCR may purchase up to 26,640,000 shares of common stock at a price of $0.13
per share and up to 94,170 shares of Class A Preferred Stock at a price of
$1,000 per share. Through December 31, 1999, GTCR has provided equity financing
in the amount of $27,525,000, consisting of 26,640,000 shares of common stock
and 24,195 shares of Class A Preferred Stock.

   In connection with the GTCR Investment, the Company entered into a
management services agreement described in Note 5 above and on November 24,
1999, the Company consummated a subordinated debt financing with GTCR,
described in Note 9 above.

   (d) Restricted Common Stock--At various dates from the period of inception
(March 18, 1999) through December 31, 1999, the Company entered into restricted
common stock agreements with members of management and senior management under
which a total of 7,893,667 shares of common stock were issued at prices ranging
from $0.13 to $5.00 per share. In connection with the reorganization of
Original ZEFER and the acquisitions described in Note 4 to the financial
statements, the Company also issued as part of the purchase consideration a
total of 1,420,800 shares of restricted common stock. The restricted common
stock vests on various dates over a period of four to five years; vesting
accelerates partially upon an IPO and fully upon the sale or liquidation of the
Company, as defined. If an employee terminates employment prior to vesting, the
Company has the option to repurchase the unvested portion of common stock at
its original purchase price.

   As consideration for the restricted common stock issued to management, the
employees paid cash and executed promissory notes payable to the Company in the
aggregate amount of $945,670 (the Subscription Notes), which have been
classified as subscriptions receivable in the accompanying financial
statements. The Subscription Notes bear interest at 5% per annum and all unpaid
principal and interest are due upon the fifth anniversary date. The
Subscription Notes are payable in full should the employee receive any proceeds
from the sale or transfer of the restricted common stock. Additionally, the
employees are required to make mandatory prepayments equal to the unpaid
principal balance multiplied by a percentage calculated as the amount of GTCR
Investment made to date divided by the total GTCR commitment of $97,500,000.

   (e) Sales to Management--During the period from inception (March 18, 1999)
through December 31, 1999, the Company sold 683,488 shares of unrestricted
common stock to management at prices ranging from $0.13 to $0.29 per share and
619 shares of unrestricted Class A Preferred Stock at a price of $1,000 per
share for total proceeds of $730,844. As consideration for the unrestricted
common and preferred stock, the employees paid $103,388 in cash and issued
promissory notes payable to the Company in the amount of $627,456, which has
been classified as subscriptions receivable in the accompanying financial
statements.

   (f) Deferred Compensation--In cases where options are granted or stock is
issued at a price below fair market value, the Company calculates compensation
as the difference between the fair market value, as determined by the Board of
Directors and/or an appraisal by an independent third party, and the exercise
or issuance price. The Company recognizes compensation expense over the vesting
term of the related instrument.

   In connection with the issuance of restricted common stock to management,
during 1999, the Company issued 1,266,667 shares at a price below the then
current fair market value, resulting in deferred compensation of $148,500 that
will be charged to operations over the vesting term of the related restricted
common stock. Also during 1999, the Company granted stock options to employees
at a price below the then-current fair market value, resulting in deferred
compensation of $546,000 that will be charged to operations over the vesting
term of the underlying options.

(12) Stock Options

   (a) Equity Incentive Plans--In June 1999, the Company adopted the 1999 Stock
Option Plan (the Option Plan), which provides for granting up to 2,000,000
shares of common stock to employees, consultants and advisors of businesses or
entities that the Company acquires who, in the opinion of the Board, are in a
position to make a significant contribution to the success of the Company and
its subsidiaries. Options granted pursuant to the Option Plan will be non-
qualified options.

   In June 1999, the Company adopted the 1999 Incentive Plan (the Incentive
Plan). The Incentive Plan may be administered by the Board or by an option
committee, as defined (in either case, the Administrator), to grant incentive
stock options, nonqualified stock options, restricted stock, unrestricted
stock, convertible securities, performance awards and cash performance awards.
The Company has reserved a total of 2,666,666 shares of common stock for future
grant under the Incentive Plan. No more than $1,000,000 may be paid to any
individual with respect to any cash performance award and the maximum number of
shares of stock subject to other awards that may be delivered to any person in
any calendar year shall be 1,000,000.

   (b) Fair Value Disclosures--The Company applies the measurement principles
of APB Opinion No. 25 in accounting for issuances of employee stock options and
SFAS No. 123 for all other stock options. Had compensation expense for employee
stock options granted been determined based on the fair value at the date of
grant as prescribed by SFAS No. 123, the net loss and net loss per share for
the period from inception through December 31, 1998, the four months ended
April 30, 1999 and the period from inception through December 31, 1999,
respectively, would have been increased to the pro forma amounts indicated
below:

</TABLE>

   For the periods indicated above, the Company calculated the minimum fair
value of each option grant on the date of grant using the Black-Scholes option
pricing model as prescribed by SFAS No. 123 using the following assumptions:

<TABLE>

   Expected volatility......................     --          --         70.0%
</TABLE>

   Based on these assumptions, the minimum fair value of options granted in the
periods indicated above was $2,272, $0 and $4,683,548, respectively. No options
were granted by Original ZEFER in the four months ended April 30, 1999. Because
the determination of fair value of all options granted after such times as the
Company becomes a public entity will include an expected volatility factor in
addition to the factors described in the preceding paragraph, the above results
may not be representative of future periods.

(13) Authorized Capital Stock--Original ZEFER

   (a) Redeemable Convertible Preferred Stock--Original ZEFER had authorized a
total of 20,000 shares of redeemable convertible preferred stock, of which
12,000 shares were designated Series A and 8,000 shares were designated Series
B. At December 31, 1998 and April 30, 1999, 12,000 shares of Series A were
issued and outstanding with an aggregate liquidation value of $1,200,000, and
no shares of Series B were issued or outstanding. The Series A was convertible
to Class B common stock of Original ZEFER on a one-for-one basis and had voting
rights. The Series A was entitled to receive quarterly dividends of $1.50 per
share, whether or not declared by the Board of Directors. The Series A was
redeemable on or before March 25, 2003.

   (b) Common Stock--Original ZEFER had authorized 168,000 shares of $.01 par
value common stock, of which 47,400 and 57,501 shares were issued and
outstanding at December 31, 1998 and April 30, 1999,

                             December 31, 1999

respectively. All shares of Original ZEFER common stock were subject to stock
restriction agreements whereby Original ZEFER could repurchase unvested shares
of common stock for the original purchase price of $.01 per share in the event
of termination of employment by the holder. At December 31, 1998 and April 30,
1999, 31,300 shares of common stock were vested.

   In connection with the acquisition of Original ZEFER by the Company on April
30, 1999, all outstanding shares of Series A redeemable convertible preferred
stock and common stock were exchanged for the purchase consideration described
in Note 1 to the financial statements.

(14) Employee Benefit Plans

   The Company has a 401(k) savings plan (the Savings Plan) that qualifies as a
defined contribution arrangement under Section 401(a), 401(k) and 501(a) of the
Internal Revenue Code. Under the Savings Plan, participating employees may
defer a percentage (not to exceed 25%) of their eligible pretax earnings up to
the Internal Revenue Service's annual contribution limit. All employees on the
U.S. payroll of the Company are eligible to participate in the Plan. The
Company will determine its contributions, if any, based on its current profits
and/or retained earnings; however, no contributions have been made since the
inception of the Savings Plan.

                         NOTES TO FINANCIAL STATEMENTS
                (Including Data Applicable to Unaudited Periods)

(1) Operations and Sale of the Company

   Spyplane, LLC (Spyplane) began operations as a California limited liability
company during May 1998. Spyplane offers integrated Internet services,
including brand creation and Web site development, to its clients.

   Spyplane is subject to risks common to rapidly growing, technology-based
companies, including limited operating history, dependence on key personnel,
rapid technological change, competition from substitute services and larger
companies and the need for continued market acceptance of Spyplane's services.

   On May 14, 1999, ZEFER Corp., Inc. (ZEFER) purchased all of the LLC Units of
Spyplane from the unit holders for $2,005,000 (the Acquisition) plus
acquisition costs of approximately $100,000. The Acquisition was accounted for
using the purchase method of accounting in accordance with the requirement of
Accounting Principles Board (APB) Opinion No. 16, Business Combinations, and,
accordingly, Spyplane's results of operations are included in those of ZEFER
beginning on May 14, 1999. The total consideration consisted of 200,000 shares
of ZEFER common stock, a promissory note in the amount of $980,000 and $1.0
million in cash.

(2) Summary of Significant Accounting Policies

   (a) Interim Financial Statements The accompanying balance sheet as of March
31, 1999 and the statements of operations, cash flows and members' equity for
the three months ended March 31, 1999 are unaudited, but, in the opinion of
management, include all adjustments, consisting only of normal recurring
adjustments necessary for a fair presentation of results for the interim
period. Certain information and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles have been omitted, although Spyplane believes that the disclosures
included are adequate to make the information presented not misleading. The
results of operations for the three months ended March 31, 1999 are not
necessarily indicative of the results to be expected for the year.

   (b) Management 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.

   (c) Revenue Recognition Spyplane's revenues are derived from professional
services that are generally provided to clients on a fixed-fee basis. Revenues
from branding and Web site design, development and implementation contracts are
recognized primarily on the percentage-of-completion method. Contracts
generally extend over a two-to-four month period. The cumulative impact of any
revision in estimates of the percent complete is reflected in the period in
which the changes become known. When the revised estimates indicate a loss,
such loss is currently provided for in its entirety. Revenues exclude
reimbursed expenses charged to and collected from clients. Unearned revenue
relates to advanced service billings.

   (d) Depreciation Spyplane provides for depreciation by charging to
operations amounts that allocate the cost of property and equipment over their
estimated useful lives using the straight-line method, using an estimated
useful life of 2 years for computers and equipment and five years for furniture
and fixtures.

   (e) Income Taxes Spyplane is treated as a limited liability company for
federal and state income tax purposes, whereby the membership owners are taxed
on their proportionate share of Spyplane's income. As a result, Spyplane does
not need to provide for federal or state income taxes.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)
                (Including Data Applicable to Unaudited Periods)


   (f) Concentration of Credit Risk Statement of Financial Accounting Standards
(SFAS) No. 105, Disclosure of Information About Financial Instruments with Off-
Balance-Sheet Risk and Financial Instruments with Concentrations of Credit
Risk, requires disclosure of any significant off-balance-sheet and credit risk
concentrations. Spyplane has no significant off-balance-sheet risk or credit
risk concentrations. Financial instruments that subject Spyplane to credit risk
consist primarily of accounts receivable. Spyplane has not experienced any
significant losses related to its accounts receivable. During the period from
inception to December 31, 1998 and the three months ended March 31, 1999, the
Company had four significant customers representing 79% and 89% of the
revenues, respectively. As of the December 31, 1999 and March 31, 1999, these
same customers had balances representing 98% and 99% of accounts receivable,
respectively.

   (g) Financial Instruments Financial instruments consist primarily of cash,
accounts receivable and accounts payable. The estimated fair value of these
instruments approximates their carrying value at December 31, 1998 and March
31, 1999 because of the short-term nature of these instruments.

   (h) Long-lived Assets Spyplane's long-lived assets consist primarily of
property and equipment. Spyplane has assessed the realizability of these assets
and believes that there is no material impairment of these assets to date.

   (i) Comprehensive Income Comprehensive income represents net income plus the
change in equity of a business enterprise during a period from transactions and
other events and circumstances from non-owner sources. The only component of
comprehensive income for the period from inception to December 31, 1998 and for
the three months ended March 31, 1999 is net income.

   (j) New Accounting Standards In June 1998, the Financial Accounting
Standards Board (FASB) issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities. SFAS No. 133, as amended by SFAS No. 137,
is effective for all fiscal quarters beginning with the quarter ending
September 30, 2000. SFAS No. 133 establishes accounting and reporting standards
for derivative instruments, including certain derivative instruments embedded
in other contracts, and for hedging activities. The Company will adopt SFAS No.
133 in its quarter ending September 30, 2000, and does not expect such adoption
will have an impact on the Company's results of operations, financial position
or cash flows.

(3) Commitments

   Spyplane leases its facility under an operating lease agreement that expires
on November 29, 2000. Future minimum rental payments due under this agreement
are approximately as follows:

(4) Members' Equity

   At December 31, 1998, Spyplane's membership consisted of two members,
Gregory Hipwell and Jason Zada. Each member owned a 50% share of Spyplane.
Income is allocated to each of the two members equally, based on the operating
agreement. Total members' draw was $141,776 for the period from inception to
December 31, 1998 and $36, 355 for the unaudited three months ended March 31,
1999.

(5) Line of Credit

   On March 18, 1999, Spyplane established a line-of-credit agreement with a
bank in the amount of $10,000. Spyplane has not borrowed against the line of
credit through October 4, 1999.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Divisions of Renaissance:

   We have audited the accompanying combined balance sheets of Neoglyphics
Media Corporation (an Illinois corporation) and Customer Management Solutions
(a division of Renaissance Worldwide, a Massachusetts corporation),
collectively the Company, as of December 31, 1998 and May 28, 1999, and the
related combined statements of operations and parent company equity (deficit)
and cash flows for the three months ended March 31, 1998, the nine-months ended
December 31, 1998, and the five months ended May 28, 1999. These combined
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 combined financial statements referred to above present
fairly, in all material respects, the financial position of the Company as of
December 31, 1998 and May 28, 1999, and the results of its operations and cash
flows for the three months ended March 28, 1998, the nine months ended December
31, 1998, and the five months ended May 28, 1999, in conformity with generally
accepted accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS

(1) Operations and Sale of the Company

   On May 28, 1999, ZEFER Corp. (ZEFER) completed its acquisition of the
Internet development and applications business of Renaissance Worldwide, Inc.,
a Massachusetts corporation (Renaissance). The acquired businesses consist of
Neogplyphics Media Corporation (NMC) and Customer Management Solutions (CMS),
collectively, the Divisions of Renaissance or the Company.

   NMC was organized under the laws of the state of Illinois in February 1995,
and is an Internet development and applications company which develops Web
sites under contractual agreements with various customers located primarily in
the United States. CMS was organized as an operating division of Renaissance in
March of 1998, and is an Internet development and applications company that
develops Web-based front-office systems for various customers located primarily
in the United States.

   In May 1999, ZEFER acquired certain net assets of the Company for
approximately $12.3 million. The consideration consisted of $10 million of
cash, 100,000 shares of ZEFER common stock valued at $50,000, a promissory note
of $2 million, plus acquisition costs of approximately $160,000. The
acquisition was accounted for using the purchase method of accounting, in
accordance with APB Opinion No. 16. The purchase price was allocated based on
the estimated fair market value of assets and liabilities assumed on the date
of acquisition.

   The accompanying combined financial statements reflect a carveout of the
Company from the consolidated financial statements of Renaissance. Prior to the
acquisition by ZEFER, the Divisions of Renaissance were operated as separate
divisions. The statements of operations for the Company reflects allocations of
the cost of shared facilities and certain administrative costs. Such costs and
expenses have been allocated to the Company based on actual usage or other
methods that approximate actual usage. Management believes that the allocation
methods are reasonable. The financial information included herein may not
necessarily reflect the financial position, results of operations or cash flows
of the Company in the future, nor what the financial position, results of
operations or cash flows would have been had it been a separate, stand-alone
company throughout the periods covered.

(2) Summary of Significant Accounting Policies

   The accompanying combined financial statements reflect the application of
certain significant accounting policies, as described in this note and
elsewhere in the notes to combined financial statements.

   (a) Management 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 periods. Actual results could differ from those estimates.

   (b) Cash and Cash Equivalents Cash equivalents are stated at cost, which
approximates fair market value. The Company considers highly liquid investments
with original maturities of 90 days or less to be cash equivalents. As of
December 31, 1998 and May 28, 1999, cash equivalents consisted of money market
accounts and commercial paper that are readily convertible to cash.

                                      F-35
<PAGE>

                            DIVISIONS OF RENAISSANCE

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)


   (c) Fair Value of Financial Instruments Financial instruments consist
principally of cash and cash equivalents, accounts receivable, and accounts
payable, line of credit and long-term debt and obligations. The estimated fair
value of these instruments approximates their carrying value.

   (d) Revenue Recognition Revenues are derived from professional services,
which are provided to clients on a time and materials or fixed-fee basis.
Revenues pursuant to time and materials contracts are generally recognized as
services are performed. Revenues pursuant to fixed-fee contracts to provide
services are recognized using the percentage-of-completion method (based on the
ratio of costs included to total estimated project costs). Contracts generally
extend over a three-to-six-month period. The cumulative impact of any revision
in estimates of the percent complete is reflected in the period in which
changes become known. When the revised estimates indicate a loss, such loss is
currently provided for in its entirety. Revenues exclude reimbursed expenses
charged to and collected from clients. Deferred revenue relates to advanced
service billings.

   (e) Due from (to) Related Party Due from (to) related parties consists of
amounts due from (to) Renaissance and other divisions within Renaissance.

   (f) Property and Equipment Depreciation is provided for using the straight-
line method, by charges to operations in amounts estimated to allocate the cost
of property and equipment over their estimated useful life of 3-5 years for
computer equipment and software, 5-10 years for office furniture and equipment
and the life of the lease for leasehold improvements.

   (g) Long-Lived Assets The Company evaluates the realizability of its long-
lived assets based on profitability and cash flow expectations for the related
asset. Management believes that, as of each of the balance sheet dates
presented, none of the Company's long-lived assets was impaired.

   (h) Concentration of Credit Risk The Company has no significant off-balance
sheet concentration of credit risks such as foreign exchange contracts, options
contracts or other foreign hedging arrangements. Financial instruments that
potentially expose the Company to concentrations of credit risk consist
primarily of cash and cash equivalents, accounts receivable, due from (to)
related parties, and long-term debt. Concentrated credit risk with respect to
accounts receivable is limited to certain customers to whom the Company makes
substantial sales. During the three months ended March 31, 1998, the nine
months ended December 31, 1998 and the five months ended May 28, 1999, the
Company had three, four and two customers representing 45%, 56% and 22% of the
revenues, respectively. As of December 31, 1998 and May 28, 1999, these same
customers had balances representing 53% and 19% of accounts receivable,
respectively.

   (i) Earnings per Share SFAS No. 128 establishes standards for computing and
presenting earnings per share and applies to entities with publicly held common
stock or potential common stock. As the Company does not have any common stock
or potential common stock during the periods presented, as the Company is
funded through investments by parent, the Company has not disclosed earnings
per share.

   (j) Comprehensive Income SFAS No. 130, Reporting Comprehensive Income,
establishes standards for reporting comprehensive income and its components in
the financial statements. Comprehensive income is defined as the change in
equity of a business enterprise during a period from transactions and other
events and circumstances from nonowner sources. The only component of
comprehensive income (loss) of the Company for the periods presented is net
income (loss).

   (k) Disclosure About Segment of an Enterprise and Related Information The
Company views its operations and business as principally one segment, Web site
design. Through May 28, 1999, substantially all of the Company's operations and
assets have been derived from and are located in the U.S.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)


   (l) New Accounting Standards In June 1998, the Financial Accounting
Standards Board (FASB) issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities. This statement establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts, and for hedging activities. It
requires that an entity recognize all derivatives as either assets or
liabilities in the balance sheet and measure those instruments at fair value.
Pursuant to SFAS No. 137, Accounting for Derivative Instruments and Hedging
Activities--Deferral of the Effective Date of FASB Statement No. 133, SFAS No.
133 is effective for all fiscal quarters of fiscal years beginning after June
15, 2000. SFAS No. 133 is not expected to have a material impact on the
Company's financial statements.

(3) Income Taxes

   For the periods presented, the results of the Company were included in the
consolidated tax return of Renaissance. The Company's policy is to record
income taxes as if it were a separate company. Accordingly, no tax benefit has
been recorded for the net losses because of uncertainty of future realization.
A full valuation allowance was recorded against the Company's net operating
loss carryforwards.

(4) Accrued Expenses

   Accrued expenses consist of the following:

(7) Parent Company Equity (Deficit)

   The financial statements of the Company have been derived from the
consolidated financial statements of Renaissance. Parent Company equity
represents the net assets (liabilities) of the Company.

(8) 401(k) Plan

   Effective January 1997, NMC established a deferred compensation plan under
Section 401(k) of the Internal Revenue Code, covering substantially all
employees. Under the plan, employees may elect to defer up to 15% of their
salary, subject to the Internal Revenue Code limits. NMC may make a matching
contribution, as well as a discretionary contribution. As of July 1, 1998 all
contributions under the plan were ceased, in conjunction with the acquisition
of NMC by Renaissance. NMC did not elect to make any matching contributions or
discretionary contribution under the plan for fiscal 1998.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Neogplyphics Media Corporation:

   We have audited the accompanying statement of financial position of
Neoglyphics Media Corporation as of December 31, 1997, and the related
statements of income 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 audits.

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

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Neoglyphics Media
Corporation at December 31, 1997, and the results of its operation and its cash
flows for the year then ended in conformity with generally accepted accounting
principles.

   As described in Note 2 to the financial statements, the Company changed its
method of recognizing revenue under fixed-fee contracts.

                               December 31, 1997

(1) Summary of Significant Accounting Policies

   (a) Nature of Operations The Company, which began operations in February,
1995, develops websites under contractual agreements with various clients
located primarily in the United States.

   (b) 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 amount of revenue and
expenses during the reported period. Actual results could differ from those
estimates.

   (c) Cash Equivalents The Company considers all highly liquid debt
instruments purchased with a maturity of three months or less to be cash
equivalents.

   (d) Allowance for Doubtful Accounts The Company maintains reserves for
potential credit losses, and such losses have been within management's
expectations.

   (e) Properties Properties, which are stated at cost, are being depreciated
or amortized over the estimated useful lives of the assets on the straight-line
method. Estimated useful lives of properties are as follows:

</TABLE>

   Due to inherent technological change in the computer industry, the period
over which computer equipment and software is being depreciated and amortized
may have to be accelerated. Depreciation and amortization of properties amounts
to $189,611 for the year ended December 31, 1997.

   (f) Intangibles Intangible assets are being amortized over the estimated
useful lives of the assets on the straight-line method. Estimated useful lives
of intangibles range from five to ten years. Amortization of intangibles
amounts to $3,935 for the year ended December 31, 1997.

   (g) Computer Software Development Costs In accordance with Statement of
Financial Accounting Standards No. 86, "Accounting for Costs of Computer
Software to be Sold, Leased or Otherwise Marketed," the Company is required to
capitalize certain software development and production costs once technological
feasibility has been achieved. Costs prior to technological feasibility is
achieved, and subsequent to the product release, are charged to operations as
incurred. Capitalized computer software development costs are reported at the
lower of unamortized cost or net realizable value. Upon initial product
release, these costs are amortized based on the straight-line method over the
estimated useful life, not to exceed three years. Fully amortized computer
software costs are removed from the financial records.

   (h) Revenue Recognition Revenue from fixed-fee contracts are recognized on
the percentage-of-completion method measured by the percentage of labor hours
incurred to date, to total labor hours for each contract, as estimated by
management. This method is used because management considers total labor hours
to be the best available measure of progress on contracts. Because of the
inherent uncertainties in estimating hours, it is possible that the Company's
estimates of costs and revenue may be revised prior to contract completion.
Changes in estimated profitability and job performance may result in revisions
to costs and income, which are recognized in the period in which the revisions
are determined. If estimated total costs for a contract indicate a loss, the
Company provides currently for the total anticipated loss on the contract.

   Contract costs include all direct labor and those indirect costs related to
contract performance. The asset, "Costs and Estimated Earnings in Excess of
Billings on Uncompleted Contracts," represents revenue recognized in excess of
amounts billed. The liability, "Billings in Excess of Costs and Estimated
Earnings on Uncompleted Contracts," represents billings in excess of revenue
recognized.

   (i) Income Taxes Effective January 1, 1997, the Company terminated its
election to be taxed as a small business corporation. Accordingly, on that
date, the Company adopted Statement of Financial Accounting Standards No. 109,
"Accounting for Income Taxes." Deferred taxes have resulted from temporary
differences between reporting income for financial reporting purposes and for
income tax purposes.

   The Company reports income on the cash basis for income tax purposes and,
accordingly, pays taxes based on when income is received and expenses are paid.
The Company depreciates its properties on the straight-line method, capitalizes
software developments cost, recognizes revenue using the percentage of
completion on fixed contracts, and provides for bad debts at the time of sale
for financial reporting purposes. Differences arise as the Company depreciates
its properties on accelerated methods, expenses all software development costs,
recognizes revenue when collected, and expenses bad debts as they occur, for
income tax purposes.

   (j) Stock Options The Company has adopted the disclosure-only provisions of
Statement of Financial Accounting Standards No. 123 (SFAS No. 123), "Accounting
for Stock-Based Compensation," but applies Accounting Principles Board Opinion
No. 25 and related interpretations in accounting for its plans.

   (k) Research and Development Costs  Research and development costs are
charged to operations when incurred and are included in operating expenses. The
amount charged in 1997 was $40,007.

(2) Change of Accounting Principle

   During 1997, the Company adopted the percentage of completion method for
recognizing revenue under fixed-fee contracts. The Company believes this method
accurately reflects periodic results of operations. The effect of this change
is to increase net income for 1997 by $393,515. Retained earnings has been
decreased by $104,756 for the effect of retroactive application of the new
method.

(3) Concentration of Credit Risk

   The Company performs ongoing credit evaluations of its customers and
generally does not require collateral. Sales are not concentrated
geographically, however, three customers accounted for 44% of total sales for
the year ended December 31, 1997, and four customers accounted for 71% of the
accounts receivable balance at December 31, 1997.

(4) Related Party Transactions

   The Company is affiliated, through common ownership, with Financial
Coordinated Services Inc. The only material transactions with its affiliate
during the year ended December 31, 1997 were short-term advances of $90,375.

(7) Computer Software Development Costs

   Computer software development coats were as follows for the year ended
December 31, 1997.

</TABLE>

   In management's opinion, the net realizable value of future sales exceeds
the carrying value of unamortized computer software development costs;
therefore, no adjustment to carrying value is required.

   Due to inherent technological change in the computer software development
industry, the period over which such capitalized computer software development
costs is being amortized may have to be accelerated.

(8) Note Payable--Bank

   The Company has a line-of-credit agreement with American National Bank and
Trust Company of Chicago for $1,500,000 dated December 12, 1997, which is

(11) Commitments and Contingencies

   (a) Capitalized Lease Obligation The Company has financed the purchase of
certain equipment through a leasing arrangement. For financial reporting
purposes, the asset and liability under this lease is capitalized at the lower
of the present value of the minimum lease payments or the fair value of the
asset. The interest rate on the capitalized lease is 16.47% and is imputed
based on the lower of the Company's incremental borrowing rate at the inception
of the lease or the lessor's implicit rate of return. The lease, which is
noncancelable, expires in June, 1999.

   The following is a schedule, by years, of future minimum lease payments
under this capital lease, together with the present value of the total minimum
lease payments, as of December 31, 1997:

</TABLE>

   Rent expense, on equipment, including month-to-month rentals, amounts to
$115,636 for the year ended December 31, 1997.

   (c) Self-insurance The Company self-insures for health insurance for its
employees. The Company limits its losses through the use of stop-loss policies
from reinsurers. Specific individual losses from claims are limited to $25,000
a year. The Company's aggregate annual loss limitation is determined by
formula. Management believes they have adequately provided for all claims
incurred in the accompanying financial statement.

   (d) Product Warranties The Company generally develops websites for customers
under contract, which usually contain unconditional warranties and support for
periods ranging up to one year. At December 31, 1997 a provision of $9,598 is
included in accrued liabilities for estimated warranty claims based on the
Company's experience.

(12) Deferred Income Taxes

   As discussed in Note I, the Company terminated its election to be taxed as a
small business corporation effective January 1, 1997. On this date, the
deferred tax liability was approximately $302,475, which has been recorded
through a charge to the deferred tax provision.

(13) Deferred Compensation Plan

   Effective January 1, 1997, the Company established a deferred compensation
plan under Section 401 (k) of the Internal Revenue Code, covering substantially
all employees. Under the plan, employees may elect to defer up to 15% of their
salary, subject to the Internal Revenue Code limits. The Company may make a
matching contribution, as well as a discretionary contribution. The Company did
not elect to make any matching contributions or discretionary contribution
under the plan for the year ended December 31, 1997.

(14) Stock Option Plan

   Effective September 13, 1996, the Company adopted a stock option plan that
provides for incentive stock options (for key employees) and nonqualified stock
options (for key individuals, including nonemployees). The total number of
shares reserved for issuance pursuant to this plan is 1,800,000.

   (a) Incentive Stock Options This part of the plan is intended to qualify
under Section 422 of the Internal Revenue Code. Options to purchase common
stock are granted at not less than the estimated fair market value at the date
of the grant, and are exercisable during a ten-year period. No options have
been granted as of December 31, 1997.

   (b) Nonqualified Stock Options As stated in Note 1, the Company has adopted
the disclosure-only provisions of Statement of Financial Accounting Standards
No. 123 (SFAS No. 123). If the Company had elected to recognize compensation
cost for the options granted during 1997, consistent with the method prescribed
by SFAS No. 123, net income would have been decreased by $25,023 for the year
ended December 31, 1997.

   The weighted-average fair value of the options granted during 1997 was
estimated, using the Black-Scholes option pricing model, using the following
assumptions:

(15) Subsequent Event

   On January 2, 1998, the Company signed a "master lease" agreement with
American National Bank and Trust Company of Chicago for the lease of various
equipment as needed in the future. On January 20, 1998, the Company financed
$95,481 of equipment purchased in December, 1997, through this master lease
agreement. The lease, which is noncancelable, expires January 20, 2000, and
bears interest at one point above the bank's base rate, which was 8.5% on
January 20, 1998. For financial reporting purposes, the asset and liability
under this lease is capitalized at the lower of present value of the minimum
lease payments or the fair value of the asset.

   The following is a schedule, by years, of future minimum lease payments
under this capital lease, together with the present value of the total minimum
lease payments, as of January 20, 1998:

                         NOTES TO FINANCIAL STATEMENTS
               (Including Data Appropriate to Unaudited Period)

(1) Organization and Sale of the Company

   Waite & Company, Inc. (the Company), a Massachusetts corporation, was
incorporated in September 1995. The Company is a management consulting firm
that works with chief executives and leadership teams in rapidly evolving
industries to assist in redefining value in their markets. The Company
specializes in the financial service, technology, health care, professional
service, entertainment and communication industries.

   The Company is subject to risks common to rapidly growing, technology-based
companies, including limited operating history, dependence on key personnel,
rapid technological change, competition from substitute services and larger
companies, and the need for continued market acceptance of the Company's
services.

   On September 13, 1999, ZEFER Corp., (ZEFER) purchased all of the
outstanding common stock of the Company from the owners for approximately
$8,148,000 (the Acquisition) plus acquisition costs of approximately $75,000.
The Acquisition was accounted for using the purchase method of accounting in
accordance with the requirement of Accounting Principles Board (APB) Opinion
No. 16, Business Combinations, and, accordingly, the Company's results of
operations are included in those of ZEFER Corporation beginning on the date of
acquisition. The transaction was financed with $8,034,052 of ZEFER cash,
approximately $75,000 of acquisition costs, and through the issuance of
400,000 shares at $.38 per share or approximately $114,000 of ZEFER Corp.
common stock issued to the owners of the Company.

(2) Summary of Significant Accounting Policies

   The accompanying financial statements reflect the application of the
accounting policies described below.

   (a) Interim Financial Statements The accompanying balance sheet as of June
30, 1999 and the statements of operations, cash flows, and stockholders'
equity for the six months ended June 30, 1999 and 1998, are unaudited, but, in
the opinion of management, include all adjustments, consisting only of normal
recurring adjustments necessary for a fair presentation of results for these
interim periods. Certain information and footnote disclosures normally
included in financial statements prepared in accordance with generally
accepted accounting principles have been omitted, although the Company
believes that the disclosures included are adequate to make the information
presented not misleading. The results of operations for the six months ended
June 30, 1999 and 1998 are not necessarily indicative of the results to be
expected for the entire fiscal year or any other interim period.

   (b) Management 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.

   (c) Revenue Recognition The Company enters into fixed-priced consulting
agreements with its customers. The Company recognizes revenue primarily on the
percentage-of-completion method. Contracts generally extend over a two-to-four
month period. The cumulative impact of any revision in estimates of the
percent complete is reflected in the period in which the changes become known.
When the revised estimates indicate a loss, such loss is currently provided
for in its entirety. Revenues exclude reimbursed expenses charged to and
collected from clients. Unearned revenue relates to advanced service billings.
Unbilled accounts receivable relates to revenues recognized in advance of
service billings.

   (d) Long-Lived Assets The Company reviews its long-lived assets for
impairment as events and circumstances indicate the carrying amount of an
asset may not be recoverable. The Company evaluates the

                                     F-54
<PAGE>

                             WAITE & COMPANY, INC.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)
                (Including Data Appropriate to Unaudited Period)

realizability of its long-lived assets based on profitability and cash flow
expectations for the related asset. Management believes that, as of December
31, 1998 and June 30, 1999, none of the Company's long-lived assets was
impaired.

   (e) Depreciation and Amortization The Company provides for depreciation and
amortization by charges to operations on a straight-line basis in amounts
estimated to allocate the cost of the assets over their estimated useful lives
of 3-5 years for computer hardware and software, 7 years for furniture and
fixtures, the life of the lease for leasehold improvements and 7 years for
office equipment.

   (f) Concentration of Credit Risk Financial instruments that subject the
Company to credit risk consist primarily of accounts receivable. For the years
ended December 31, 1997 and 1998 and the six months ended June 30, 1998 and
1999 the Company had three, two, two and three significant customers
representing 94%, 65%, 75% and 60% of revenues, respectively. As of December
31, 1997 and 1998 and June 30, 1999, the Company had two, three and three
customers representing 100%, 93% and 82% of the accounts receivable balance,
respectively.

   (g) Fair Value of Financial Instruments The Company's financial instruments
consist of accounts receivable and accounts payable. The estimated fair value
of these financial instruments approximates their carrying value at December
31, 1998 and June 30, 1999, because of the short-term nature of these
instruments.

   (h) Comprehensive Income The Company adopted SFAS No. 130, Reporting
Comprehensive Income, effective January 1, 1998. SFAS No. 130 establishes
standards for the display of comprehensive income and its components in a full
set of financial statements. Comprehensive income represents net income plus
the change in equity of a business enterprise resulting from transactions and
events and circumstances from nonowner sources. The only component of
comprehensive income for the year ended December 31, 1997 and 1998 and the six
months ended June 30, 1998 and 1999 is net income.

   (i) New Accounting Standard In June 1998, the Financial Accounting Standards
Board (FASB) issued SFAS No. 133, Accounting for Derivative Instruments and
Hedging Activities. SFAS No. 133, as amended by SFAS No. 137, is effective for
all fiscal quarters beginning with the quarter ending September 30, 2000. SFAS
No. 133 establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts, and for hedging activities. The Company will adopt SFAS No. 133 in
its quarter ending September, 30, 2000 and does not expect such adoption to
have an impact on the Company's results of operating financial position or cash
flows.

(3) Income Taxes

   The Company has elected to be treated as a Subchapter S corporation for
federal and state income tax purposes. Under this election, for federal income
taxes and certain state income taxes, the taxable income of the Company is
reported by the stockholders of the Company on their personal income tax
returns. Accordingly, no provision for income taxes has been made in the
accompanying statement of operations. The Company has accrued for tax
distributions made to shareholders of approximately $40,000 for the period
ending December 31, 1997. All tax distributions made for the period ended
December 31, 1997 and 1998, and for the six months ended June 30, 1998 and
1999, were distributed to shareholders prior to the end of the respective
periods.

   The pro forma income tax adjustment represents the adjustment necessary to
provide for federal, additional state and foreign corporate income taxes as if
the election to be treated as an S corporation were not made, and the Company
was subject to federal and state corporate income taxes.

               (Including Data Appropriate to Unaudited Period)


(4) Stockholders' Equity

   The Company has authorized a total of 200,000 shares of common stock with
no par value. As of December 31, 1997 and 1998 and June 30, 1999, the Company
has issued and outstanding 1,030 shares of common stock. During fiscal 1997,
the Company issued 30 shares of common stock to a board member for no cash
consideration. The effect of this transaction is reflected in the statement of
operations for the year ended December 31, 1997.

(5) Commitments

   (a) Operating Leases The Company leases its facility under operating leases
that expire through August 2000.

   Approximate minimum payments required under operating leases as of December

(6) Employee Benefit Plan

   In February 1997, the Company adopted a 401(k) savings plan (the Plan) for
eligible employees. Each participant may elect to contribute up to 15% of his
or her compensation for the plan year, subject to certain Internal Revenue
Service limitations. The Company matches 50% of the first 3% of employee
contributions. For the years ended December 31, 1997 and 1998 and the six
months ended June 30, 1998 and 1999, the Company contributed approximately
$14,000, $16,000, $9,000 and $13,000 to the Plan, respectively. Subsequent to
the acquisition of the Company by Zefer Corp. (see Note 7) the Plan was
terminated.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To ZEFER Corp.:

   We have examined the pro forma adjustments reflecting the transactions
described in the pro forma combined condensed financial statements and the
application of those adjustments to the historical amounts in the accompanying
pro forma combined condensed statement of operations for the year ended
December 31, 1998. The historical condensed financial statements for the year
ended December 31, 1998 have been derived from the historical financial
statements of ZEFER Corp. (a predecessor entity incorporated in March 1998 and
hereinafter referred to as Original ZEFER), the Divisions of Renaissance,
Spyplane, LLC and Waite & Co., all of which were audited by us. Such financial
statements and our reports thereon appear elsewhere in this registration
statement. These pro forma adjustments are based upon management's assumptions
described in the notes to pro forma combined condensed financial statements.
Our examination was made in accordance with standards established by the
American Institute of Certified Public Accountants and, accordingly, included
such procedures as we considered necessary in the circumstances.

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

   In our opinion, management's assumptions provide a reasonable basis for
presenting the significant effects directly attributable to the above mentioned
transactions described in the pro forma combined condensed financial
statements, the related pro forma adjustments give appropriate effect to those
assumptions, and the pro forma column reflects the proper application of those
adjustments to the historical financial statement amounts in the pro forma
combined condensed statements of operations for the year ended December 31,
1998.

              REVIEW REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To ZEFER Corp.:

   We have reviewed the pro forma adjustments reflecting the transactions
described in the pro forma combined condensed financial statements and the
application of those adjustments to the historical amounts in the accompanying
pro forma combined condensed statement of operations for the year ended
December 31, 1999. The historical condensed financial statements for the year
ended December 31, 1999 have been derived from the historical financial
statements of ZEFER Corp. (the Company) for the period from inception (March
18, 1999) through December 31, 1999, Original ZEFER for the four months ended
April 30, 1999 and the Divisions of Renaissance for the five months ended May
28, 1999. All of such financial statements were audited by us and appear
elsewhere in this registration. The historical condensed financial statements
are derived from the historical unaudited financial statements of Spyplane, LLC
for the period from January 1, 1999 through May 14, 1999 and Waite & Co. for
the eight months ended August 31, 1999, which appear elsewhere in this
registration statement. Such pro forma adjustments are based on management's
assumptions as described in the notes to pro forma combined condensed financial
statements. Our review was conducted in accordance with standards established
by the American Institute of Certified Public Accountants and, accordingly,
included such procedures as we considered necessary in the circumstances.

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

   A review is substantially less in scope than an examination, the objective
of which is the expression of an opinion on management's assumptions, the pro
forma adjustments and the application of those adjustments to historical
financial information. Accordingly, we do not express such an opinion on the
pro forma adjustments or the application of such adjustments to the pro forma
combined condensed statements of operations for the year ended December 31,
1999. Based on our review, however, nothing came to our attention that caused
us to believe that management's assumptions do not provide a reasonable basis
for presenting the significant effects directly attributable to the above
mentioned transactions described in the pro forma combined condensed financial
statement, that the related pro forma adjustments do not give appropriate
effect to those assumptions, or that the pro forma column does not reflect the
proper application of those adjustments to the historical financial statement
amounts in the pro forma combined condensed statement of operations for the
year ended December 31, 1999.

             PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS

                                (Unaudited)

OVERVIEW

   ZEFER Corp., (the Company), was incorporated in Delaware on March 18, 1999
and is an Internet consulting and implementation firm. In March 1999, the
Company was funded with $500,000 in cash through the sale of common stock to
GTCR Golder Rauner, L.L.C. (GTCR), which also committed to fund an additional
$97.0 million to fund the Company's acquisitions and operations.

   On April 30, 1999, the Company acquired all the stock of Original ZEFER, an
Internet professional services firm. The acquisition was accounted for using
the purchase method of accounting. The Company acquired all the stock of
Original ZEFER for the net purchase price of $7,657,000, including acquisition
costs of approximately $125,000. The total purchase price was allocated as
follows: $1,136,000 of tangible assets, $4,725,000 of assumed liabilities and
$11,246,000 of intangible assets. The purchase price consisted of approximately
$7,100,000 in cash and 3,456,000 shares of the Company's common stock valued at
$.13 per share.

   On May 14, 1999, the Company acquired all of the LLC units of Spyplane, LLC
(Spyplane), an integrated provider of internet services, including brand
creation and web site development, formed in California as a limited liability
company in May 1998. The acquisition was accounted for using the purchase
method of accounting. The Company acquired all of the LLC units of Spyplane for
a net purchase price of $2,105,000, including acquisition costs of
approximately $100,000. The total purchase price was allocated as follows:
$425,000 of tangible assets, $604,000 of assumed liabilities and $2,284,000 of
intangible assets. The purchase price consisted of approximately $1,000,000 in
cash, 200,000 shares of the Company's common stock valued at $.13 per share and
a $980,000 subordinated note to the Spyplane founders. The note is due on May
14, 2001 and accrues interest at 8% per year.

   On May 28, 1999, the Company acquired the assets of two divisions of
Renaissance Worldwide, Inc. (Renaissance): Customer Management Solutions (CMS)
and Neoglyphics Media Corporation (NEO), which are collectively referred to as
the Divisions of Renaissance. CMS began operations during May 1998 as an
operating division of Renaissance, and is an Internet development and
applications company that develops web-based front-office systems. NEO was
organized in 1995 as an internet development and applications company which
develops web sites under contract with various customers. NEO existed as a
division of Renaissance for the ten months ended December 31, 1998 and for the
period from January 1, 1999 to May 28, 1999. The acquisition was accounted for
using the purchase method of accounting. The net purchase price of $12,210,000,
including acquisition costs of approximately $160,000, was allocated as
follows: $5,961,000 of tangible assets, $1,895,000 of assumed liabilities and
$8,144,000 of intangible assets. The purchase price consisted of $10,000,000 in
cash, 400,000 shares of the Company's common stock valued at $.13 per share and
a $2,000,000 subordinated note to Renaissance. The note bears interest at the
30-day LIBOR rate plus 2% and is payable in quarterly installments of $250,000
beginning in May 2000 and is convertible at the option of the holder into the
Company's common stock at a conversion price equal to 80% of the per share
price to the public of the Company's common stock in an initial public offering
(IPO).

                                (Unaudited)

   On September 13, 1999, the Company acquired the stock of Waite & Company,
Inc. (Waite), a management consulting firm that works with chief executives and
leadership teams in redefining value in their markets. The acquisition was
accounted for using the purchase method of accounting. ZEFER acquired all of
the stock of Waite for a net purchase price of approximately $8,223,000,
including acquisition costs of approximately $75,000. The total purchase price
was allocated as follows: $1,852,000 of tangible assets, $4,727,000 of assumed
liabilities and $11,098,000 of intangible assets. The purchase price consisted
of approximately $8,034,000 in cash and 400,000 shares of the Company's common
stock valued at $.29 per share. Waite was incorporated in 1995. In connection
with the acquisition, several employees of Waite signed employment agreements
with the Company. Those agreements provide for certain non-compete arrangements
with the employees for 12 months whereby the founders can not compete with the
Company's customers. Also, there is an extended 18-month period whereby the
founders are limited to the extent that they can compete in the market place.

   The following unaudited pro forma combined condensed financial statements
have been prepared in accordance with generally accepted accounting principles
and give effect to the transactions described above. The unaudited pro forma
combined condensed statement of operations for the year ended December 31, 1998
combines the historical statements of operations of (i) Original ZEFER for the
period from inception (March 19, 1998) to December 31, 1998, (ii) Spyplane for
the period from inception (May 7, 1998) to December 31, 1998 and (iii) the
Divisions of Renaissance and Waite for the year ended December 31, 1998. The
unaudited pro forma combined condensed statement of operations for the year
ended December 31, 1999 combines the historical statements of operations of (i)
the Company for the period from inception (March 18, 1999) through December 31,
1999, (ii) Original ZEFER for the period from January 1, 1999 through its date
of acquisition (April 30, 1999), (iii) Spyplane for the period from January 1,
1999 through its date of acquisition (May 14, 1999), (iv) the Divisions of

ZEFER, Spyplane, the Divisions of Renaissance and Waite for the periods
subsequent to their respective dates of acquisition have been included in the
results of operations of the Company. The unaudited pro forma combined
condensed statements of operations assume that the acquisitions were
consummated on January 1, 1998 and include pro forma adjustments to reflect
annual amounts of amortization, compensation and interest expense, as described
in the notes to pro forma combined condensed statements of operations. The
unaudited pro forma combined condensed statements of operations do not purport
to be indicative of the results which would have been reported had the
acquisitions been consummated at this date, nor do they purport to be
indicative of the results of operations which may be expected in the future.
These unaudited pro forma combined condensed financial statements should be
read in conjunction with the audited financial statements and notes thereto of
the Company, Original ZEFER, the Divisions of Renaissance, Spyplane and Waite.

Item 14. Indemnification of Directors and Officers

   Article SEVENTH of our Certificate of Incorporation provides that none of
our directors shall be personally liable for any monetary damages for any
breach of fiduciary duty as a director, except to the extent that the Delaware
General Corporation Law prohibits the elimination or limitation of liability of
directors for breach of fiduciary duty.

   Article EIGHTH of our Certificate of Incorporation provides that each
director and officer:

     (a) shall be indemnified by us against all expenses (including
  attorneys' fees), judgments, fines and amounts paid in settlement incurred
  in connection with any litigation or other legal proceeding (other than an
  action by or in our right brought against him by virtue of his position as
  our director or officer if he acted in good faith and in a manner he
  reasonably believed to be in, or not opposed to, our best interests and,
  with respect to any criminal action or proceeding, had no reasonable cause
  to believe his conduct was unlawful and

     (b) shall be indemnified by us against all expenses (including
  attorneys' fees) and amounts paid in settlement incurred in connection with
  any action by or in our right brought against him by virtue of his position
  as our director or officer if he acted in good faith and in a manner he
  reasonably believed to be in, or not opposed to, our best interests, except
  that no indemnification shall be made with respect to any matter as to
  which such person shall have been adjudged to be liable to us, unless a
  court determines that, despite such adjudication but in view of all of the
  circumstances, he is entitled to indemnification of such expenses.

   Notwithstanding the foregoing, to the extent that a director or officer has
been successful, on the merits or otherwise, including, without limitation, the
dismissal of an action without prejudice, he is required to be indemnified by
us against all expenses (including attorneys' fees) incurred in connection
therewith. Expenses shall be advanced to a director or officer at his request,
provided that he undertakes to repay the amount advanced if it is ultimately
determined that he is not entitled to indemnification for such expenses.

                                      II-1
<PAGE>

   Indemnification is required to be made unless we determine that the
applicable standard of conduct required for indemnification has not been met.
In the event of a determination by us that the director or officer did not meet
the applicable standard of conduct required for indemnification, or if we fail
to make an indemnification payment within 60 days after such payment is claimed
by such person, such person is permitted to petition the court to make an
independent determination as to whether such person is entitled to
indemnification. As a condition precedent to the right of indemnification, the
director or officer must give us notice of the action for which indemnity is
sought and we have the right to participate in such action or assume the
defense thereof.

   Article EIGHTH of our Certificate of Incorporation further provides that the
indemnification provided therein is not exclusive and provides that in the
event that the Delaware General Corporation Law is amended to expand the
indemnification permitted to directors or officers we must indemnify those
persons to the fullest extent permitted by such law as so amended.

   Section 145 of the Delaware General Corporation Law provides that a
corporation has the power to indemnify a director, officer, employee or agent
of the corporation and certain other persons serving at the request of the
corporation in related capacities against amounts paid and expenses incurred in
connection with an action or proceeding to which he is or is threatened to be
made a party by reason of such position, if such person shall have acted in
good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation and, in any criminal proceeding, if such
person had no reasonable cause to believe his conduct was unlawful; provided
that, in the case of actions brought by or in the right of the corporation, no
indemnification shall be made with respect to any matter as to which such
person shall have been adjudged to be liable to the corporation unless and only
to the extent that the adjudicating court determines that such indemnification
is proper under the circumstances.

   Under Section 7 of the Underwriting Agreement, the underwriters are
obligated, under certain circumstances, to indemnify our directors and officers
against certain liabilities, including liabilities under the Securities Act of
1933. Reference is made to the form of Underwriting Agreement filed as Exhibit
1 hereto.

statements or notes to those statements.

Item 17. Undertakings

   Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to our directors, officers and controlling persons pursuant to
the provisions contained in our Certificate of Incorporation and the laws of
the State of Delaware, or otherwise, we have been advised that in the opinion
of the Securities and Exchange Commission such indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by us of expenses incurred or paid by a
director, officer or controlling person of us 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, we will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

   We hereby undertake 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.

                                      II-6

   We hereby undertake 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 us pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective.

     (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.

<PAGE>

     2.6  Post-Closing Adjustments.  The Purchase Price set forth in Section 2.3
          ------------------------
shall be subject to adjustment after the Closing Date as follows:


          (a) As promptly as possible after the Closing Date (but in any event
not later than 45 days thereafter), the Buyer shall prepare and deliver to
Renaissance a statement of Net Assets (the "Initial Closing Statement") as of
the close of business on the Closing Date (without giving effect to the
transactions contemplated by this Agreement).  The accounting principles used in
preparing Exhibit A-1 and Exhibit A-2 are set forth in those Exhibits.  The
          ------- ---     ------- ---
Buyer shall prepare the Initial Closing Statement in accordance with GAAP and on
a basis consistent with the accounting principles used in preparing Exhibit A-1
                                                                    ------- ---
and Exhibit A-2 (to the extent such accounting principles are consistent with
    ------- ---
GAAP).  The Initial Closing Statement shall also set forth the determination of
the Purchase Price, as adjusted pursuant to this Section 2.6.

          (b) Renaissance shall deliver to the Buyer within 30 days after
receiving the Initial Closing Statement a detailed statement describing any
objections thereto.  Failure of Renaissance to so object to the Initial Closing
Statement shall constitute acceptance thereof by Renaissance, whereupon the
Initial Closing Statement shall be deemed to be the Closing Statement.  The
Buyer and Renaissance shall use reasonable efforts to resolve any such
objections, but if they do not reach a final resolution within 45 days after the
Buyer has received Renaissance's statement of objections, the Buyer and
Renaissance shall engage the Boston, Massachusetts office of KPMG (or if such
accountants are unable or refuse to serve in such capacity, such other
nationally recognized accounting firm that is not the primary independent
accounting firm for either of the parties as may be designated by the Boston
office of the American Arbitration Association) (the "Neutral Accountants") to
resolve any remaining objections.  The Neutral Accountants promptly shall
determine whether the objections raised by Renaissance are appropriate in light
of the requirements of Section 2.6(a).  The Initial Closing Statement shall be
adjusted to the extent such objections are determined by the Neutral Accountants
to be appropriate and, as so adjusted, shall be the "Closing Statement."  Such
determination by the Neutral Accountants shall be conclusive and binding upon
the parties, absent fraud or manifest error.  Nothing herein shall be construed
to authorize or permit the Neutral Accountants to determine (i) any questions or
matter whatever under or in connection with this Agreement except the
determination of what adjustments, if any, must be made in the items reflected
in the Initial Closing Statement that are the subject of objections by
Renaissance, or (ii) an adjustment to an item on the Initial Closing Statement
that is outside of the range defined by amounts as finally proposed by
Renaissance and the Buyer, respectively.

                                      -15-
<PAGE>

          (c) If the Net Assets as shown on the Closing Statement are equal to
or greater than $5,886,891 and less than or equal to $6,886,891, the Purchase
Price shall equal $12,000,000.

          (d) If the Net Assets as shown on the Closing Statement are less than
$5,886,891, the Purchase Price shall equal $12,000,000 less the amount of such
deficiency, and Renaissance shall pay promptly to the Buyer an amount equal to
such deficiency.

          (e) If the Net Assets as shown on the Closing Statement are more than
$6,886,891, the Purchase Price shall equal $12,000,000 plus the amount of such
excess, and the Buyer shall pay promptly to Renaissance, an amount equal to such
excess.

          (f) Any payments required to be made by Renaissance to the Buyer, or
by the Buyer to Renaissance, pursuant to this Section 2.6 shall be made by wire
transfer or other delivery of immediately available funds, within three business
days after the date on which the Closing Statement is finally determined
pursuant to this Section 2.6.

          (g) If the Purchase Price is adjusted pursuant to this Section 2.6,
the allocation of the Purchase Price among the Acquired Assets shall be
appropriately modified to reflect increases or decreases in the various asset
categories that give rise to such adjustments to the maximum extent allowable
under Section 1060 of the Code.

          (h) The Buyer, on the one hand, and Renaissance, on the other hand,
shall share equally the fees and expenses of the Neutral Accountants in
connection with the resolution of any dispute pursuant to Section 2.6(b) above.

     2.7  Further Assurances.  At the Closing and at any time and from time to
          ------------------
time thereafter, at the request of the Buyer and without further consideration,
the Sellers shall promptly execute and deliver such instruments of sale,
transfer, conveyance and assignment and take all such other action as the Buyer
may determine is necessary to more effectively transfer, convey and assign to
the Buyer, and to evidence and confirm the Buyer's rights to, title in and
ownership of, the Business and the Acquired Assets, to place the Buyer (through
its ownership of the Acquired Assets) in actual possession and operating control
of the assets, properties and business of the Business, to assist the Buyer in
exercising all rights with respect thereto and to carry out the purpose and
intent of this Agreement.

                                      -16-

     2.8  Transaction Taxes.  Any and all federal, state, county, local or
          -----------------
foreignsales, use, value added, excise, stamp, transfer and other Taxes not in
the nature of income taxes, fees and duties (including any interest, additions
to tax and penalties with respect thereto) and any and all transfer, recording
or similar fees and charges imposed in connection with the consummation of the
transactions contemplated by this Agreement shall be borne by the Sellers.

     2.9  Restricted Assets.
          -----------------

          (a) The Sellers shall use all reasonable efforts, and the Buyer shall
cooperate reasonably with the Sellers, (i) to promptly obtain the consents and
waivers necessary to convey or cause to be conveyed to the Buyer all of the
Restricted Assets, and (ii) as of and subject to the occurrence of the Closing,
to promptly convey or cause to be conveyed to the Buyer the Restricted Assets
for which the Sellers have received the necessary consents and waivers;
provided, however, that the Sellers shall not amend or change any Restricted
Asset without the prior written consent of the Buyer unless the Sellers
reasonably deem it necessary to preserve the value of the Restricted Asset.  The
Sellers shall cooperate with the Buyer in making applications and filings or
taking any other action necessary for the Buyer to obtain such franchises,
licenses, permits or other instruments or agreements, if any, as are
substantially equivalent to any Restricted Assets that are not assignable to
Buyer as a matter of law.  In no event shall the Buyer's cooperation hereunder
require the Buyer to make any payments or incur any out-of-pocket expenses,
except that the Buyer shall reimburse the Sellers on an equitable basis for any
consideration paid, with the prior approval of the Buyer, to any person from
whom a consent or waiver is requested.  In no event shall either Seller be
required to make any payments or incur any out-of-pocket expenses in connection
with performing its obligations under this Section 2.9 relating to any client
services agreement.

          (b) To the extent that the consents and waivers necessary to assign,
transfer sublease or sublicense any of the Restricted Assets are not obtained,
the Sellers shall, commencing on the Closing Date and continuing for the
duration of each such Restricted Asset, use reasonable efforts to (i) provide to
the Buyer the benefits of any such Restricted Asset not assigned, transferred or
subleased due to the failure or inability of either Seller to obtain such
consent or waiver, (ii) cooperate with the Buyer to reach a reasonable and
lawful arrangement designed to provide such benefits to the Buyer during such
period, and (iii) enforce at the request of the Buyer, or allow the Buyer to
enforce (and, for such purpose, each Seller hereby constitutes and appoints the
Buyer as its true and lawful attorney-in-fact), any rights of either Seller
under any such Restricted Asset against the issuer thereof or the other party or
parties thereto (including the right to elect to terminate such of the foregoing
in accordance with the terms thereof upon the request of the Buyer); provided,

                                      -17-
<PAGE>

however, that the reasonable costs and expenses of either Seller incurred at the
Buyer's request with respect to any of the actions contemplated under clause
(iii) above shall be promptly paid or reimbursed by the Buyer to Renaissance.
At the end of each such period, neither Seller shall have any further duties or
obligations under this Section 2.9 with respect to such Restricted Asset and the
failure or inability to obtain any necessary consent or waiver with respect
thereto shall not be a breach of this Agreement so long as such Seller has
carried out its obligations under this Section 2.9.

          (c) To the extent that the Buyer is provided the benefits of any
Restricted Asset pursuant to clause (b) of this Section 2.9, the Buyer shall
perform for the benefit of the issuer thereof, or the other party or parties
thereto, the obligations of either Seller thereunder or in connection therewith,
but only to the extent that (i) such action by the Buyer would not result in any
default thereunder or in connection therewith and (ii) such obligation would
have been an Assumed Liability but for the non-assignability or non-
transferability thereof; provided, however, that if the Buyer shall fail to
perform to the extent required herein, the applicable Seller shall thereafter
cease to be obligated under this Section 2.9 to provide the Buyer with any
benefits in respect of the Restricted Asset which is the subject of such failure
to perform unless and until such situation is remedied or, at the sole option of
the applicable Seller, the Buyer shall promptly pay or reimburse such Seller for
all costs reasonably incurred by such Seller to remedy such failure to perform
during such period of failure of performance.

material breach or default, and no event has occurred which with notice or lapse

dispute between the parties thereto.

     3.11 Accounts Receivable; Contracts in Progress.  All Accounts Receivable
          ------------------------------------------
reflected on the Financial Statements are valid receivables arising from
services rendered in the Ordinary Course of Business.  A report showing the
aging of all Accounts Receivable is attached as Section 3.11 of the Disclosure
Schedule.  All Accounts Receivable reflected in the financial or accounting
records of the NMC Business or the CMS Business that have arisen since the date
of the Financial Statements are valid receivables arising from services rendered
in the Ordinary Course of Business.  For purposes of this Section 3.11, a "valid
receivable" is a receivable in respect of which the amounts so billed are
consistent with the Sellers' billing policies.  As to each Contract in Progress
as of the date of this Agreement which contemplates the payment of amounts in
excess of $50,000, Section 3.11 of the Disclosure Schedule sets forth a
reasonable description of such Contracts in Progress.

     3.12 Employees.
          ---------

          (a) The Sellers have previously provided to the Buyer a list of all
employees of the NMC Business or the CMS Business as of April 30, 1999 and their
rates of compensation.  To the Knowledge of either Seller, no employee of either
Seller involved in the NMC Business or the CMS Business intends not to accept
employment with the Buyer.  Except as set forth in Section 3.12(a) of the
Disclosure Schedule, neither Seller has any employment or consulting agreements
that are not terminable at will without penalty.  Neither the execution and
delivery of this Agreement nor the consummation of the transactions contemplated
hereby will trigger or otherwise result in any obligation of either Seller to
pay severance or related costs under any employment or consulting agreement.

                                      -24-
<PAGE>

          (a) Section 3.13(a) of the Disclosure Schedule contains a complete and

of all Employee Benefit Plans which have been reduced to writing have been made
available to the Buyer, and the Sellers have made available to the Buyer written
summaries of any such plans which have not been reduced to writing.

          (b) The Internal Revenue Service has issued a favorable determination
letter with respect to the qualification of each of the Employee Benefit Plans
which is an "employee pension benefit plan" as such term is defined in Section
3(2) of ERISA (collectively, the "Retirement Plans") and any corresponding trust
intended to qualify under Sections 401(a) and 501(a) of the Code.  No such
determination letter has been revoked and no such revocation has been
threatened, and nothing has occurred since the date of each such most recent
determination letter that could reasonably be expected to cause the relevant
Retirement Plan or trust to lose such qualification or exemption.

          (c) No Employee Benefit Plan is subject to Title IV of ERISA and
neither Seller is subject to any liability to the PBGC for any termination of
any Employee Benefit Plan.  Neither Seller nor any ERISA Affiliate contributes
to or has an obligation to contribute to, or has at any time within six years
prior to the Closing Date contributed to or had an obligation to contribute to,
a "multiemployer plan" as defined in Section 4001(a)(3) of ERISA and neither
Seller reasonably expects to incur any liability with respect to any such
multiemployer plan.

          (d) No Employee Benefit Plan provides benefits after termination of
employment to any current or former employee of either Seller involved in the
NMC Business or the CMS Business (or to any beneficiary of any such current or
former employee), including but not limited to retiree health coverage and
deferred compensation, but excluding continuation of health coverage required to
be continued under Section 4980B of the Code and insurance conversion privileges
under state law.

agreement with any director, executive officer or other employee of either
Seller involved in the NMC Business or the CMS Business with an annual salary
including bonus in excess of $75,000 (A) the benefits of which are contingent,
or the terms of which are materially altered, upon the occurrence of a
transaction involving the NMC Business or the CMS Business of the nature of any
of the transactions contemplated by this Agreement, (B) providing any term of
employment or compensation guaranty, or (C) providing severance benefits or
other benefits after the termination of employment of such director, executive
officer or employee; (ii) agreement, plan or arrangement under which any person
may receive payments from either Seller that may be subject to the tax imposed
by Section 4999 of the Code or included in the determination of such person's
"parachute payment" under Section 280G of the Code; and (iii) agreement or plan
binding either Seller, including without limitation any Employee Benefit Plan,
any of the benefits of which will be increased, or the vesting of the benefits
of which will be accelerated, by the occurrence of any of the transactions
contemplated by this Agreement or the value of any of the benefits of which will
be calculated on the basis of any of the transactions contemplated by this
Agreement.

either Seller has delivered products for manufacturing, processing, packaging or
distribution.  Neither Seller is aware of any releases of Materials of
Environmental Concern at parcels of real property or facilities other than those
owned, leased, operated or controlled by either Seller that could reasonably be
expected to have a material impact on such real property or facilities resulting
in any liability to either Seller.

          (c) Set forth in Section 3.14(c) of the Disclosure Schedule is a list
of all environmental reports, site surveys, subsurface studies, investigations
and audits (whether conducted by or on behalf of either Seller or a third party,

Seller, directed by a

          ----------------------------------------------
respect to its operations other than the NMC Business or the CMS Business) nor
any Affiliate of either Seller (a) has any claim or cause of action against the
Acquired Assets, or (b) owes any money in connection with the NMC Business or
the CMS Business to either Seller.  Section 3.15 of the Disclosure Schedule
describes any transaction or relationships between either Seller (with respect
to its operations other than the NMC Business or the CMS Business) and its
Affiliates, on the one hand, and the NMC Business or the CMS Business, on the
other hand.

     3.16 Brokers' Fees.  Neither Seller has any liability or obligation to pay
          -------------
any fees or commissions to any broker or finder with respect to the transactions
contemplated by this Agreement.

either the CMS Business or the NMC Business during the last full fiscal year and
the amount of revenues accounted for by such customer during each such period.
Except as set forth on Section 3.17 of the Disclosure Schedule, no such customer
of the NMC Business or the CMS Business has indicated since January 1, 1998 that
it will, nor does either Seller have any reason to believe that any such
customer will terminate any of the Assigned Contracts.  There are no suppliers

alternative sources of supply, or comparable products, are not available on
comparable terms and conditions.

each lease or sublease is assignable by the appropriate Seller to the Buyer
without the consent or approval of, or any payment to, any party; assuming the

performs all of lessee's obligations thereunder, all such leases or subleases
will continue to be legal, valid, binding, enforceable and in full force and
effect immediately following the Closing in accordance with the terms thereof as

breach or default with the giving of notice or the passage of time or both) any
such lease or sublease;

          (c) neither Seller nor, to the Knowledge of either Seller, any other

above, the Sellers shall make available to the Buyer such financial information
and reasonable assistance with respect to the NMC Business and the CMS Business,
including without limitation providing to the Buyer and its authorized
representatives reasonable access to the workpapers of Renaissance's accountants
relating to the operation of the NMC Business or the CMS Business prior to the
Closing Date, as is reasonably necessary for the Buyer to prepare on a timely
basis the financial statements required in connection with the preparation of a
registration statement under the Securities Act of 1933, as amended.

          (c) In addition to all files and documents required to be provided
pursuant to this Agreement or the Ancillary Agreements, promptly upon request by
the Buyer made at any time following the Closing Date, the appropriate Seller
shall authorize the release to the Buyer of all files pertaining to the Acquired
Assets or the Business held by any federal, state, county or local authorities,
agencies or instrumentalities.

     7.5  Cooperation in Litigation.  From and after the Closing Date, each
          -------------------------
party shall fully cooperate with the other in the defense or prosecution of any
litigation or proceeding already instituted or which may be instituted hereafter
against or by such other party relating to or arising out of the conduct of the
NMC Business or the CMS Business prior to or after the Closing Date (other than
litigation among the Sellers, the Buyer and/or their respective Subsidiaries or
Affiliates arising out of the transactions contemplated by this Agreement or the
Ancillary Agreements).  The party requesting such cooperation shall pay the
reasonable out-of-pocket expenses incurred in providing such cooperation
(including legal fees and disbursements) by the party providing such cooperation
and by its officers, directors, employees and agents, but shall not be
responsible for reimbursing such party or its officers, directors, employees and
agent for their time spent in such cooperation.

     7.6  Collection of Accounts Receivable and Contracts in Progress.
          -----------------------------------------------------------

          (a) The Sellers shall forward promptly to the Buyer any monies, checks
or instruments received by either of them after the Closing Date with respect to
the Accounts Receivable and the Contracts in Progress.  The Sellers hereby
authorize the Buyer to open any and all mail addressed to either Seller (if
delivered to the Buyer) received on or after the Closing Date and hereby grants
to the Buyer a power of attorney to endorse and cash any checks or instruments
payable or endorsed to either Seller or its respective order and received by the
Buyer with respect to the Acquired Assets, the NMC Business or the CMS Business.
The Sellers shall provide to the Buyer such reasonable assistance as the Buyer
may request with respect to the collection of any such Accounts Receivable and
Contracts in Progress, provided the

                                      -41-
<PAGE>

Buyer pays the reasonable out-of-pocket expenses of the Sellers and their
respective officers, directors and employees incurred in providing such
assistance. From and after the Closing, the Sellers shall refer all customer
inquiries relating to Accounts Receivable or Contracts in Progress to the Buyer.

          (b) Any Account Receivable existing as of the Closing Date which does
not appear in the Initial Closing Statement pursuant to Section 2.6(a) or as to
which either Seller pays the Buyer Damages in an amount equal to the face amount
of such Account Receivable pursuant to Section 8.1 because of a breach of
Section 3.11 shall promptly be assigned by the Buyer to the appropriate Seller
(without recourse) and any funds thereafter collected by the Buyer with respect
to such Accounts Receivable shall be paid by the Buyer to the appropriate
Seller.

     7.7  Employees.  Effective as of the Closing, the Buyer shall offer
          ---------
employment to each employee employed primarily in the conduct of the NMC
Business or the CMS Business (except for those designated on Schedule 7.7) who
                                                                       ----
is actively at work as of the Closing, terminable at the will of the Buyer or as
otherwise agreed to between the Buyer and such employee.  Except as otherwise
specifically required by applicable law, the Buyer shall not have any obligation
to employ or offer employment to any employee of the NMC Business or the CMS
Business other than as provided in the preceding sentence.  The Buyer shall have
complete discretion to change any of the terms or conditions of employment,
compensation or benefits relating to any such employee at any time.  The parties
hereto do not intend to create any third-party beneficiary rights respecting any
employee as a result of the provisions herein and specifically hereby negate any
such intention.  Each Seller hereby consents to the hiring of such employees by
the Buyer and waives, to the extent necessary to allow the employment by the
Buyer of such employees, any claims or rights such Seller may have against the
Buyer or any such employee under any noncompetition, confidentiality or
employment agreement.

     7.8  Employee Notices.  The Sellers shall make such notices to employees as
          ----------------
shall be required by any applicable Laws and Regulations or by any agreements
(including any notices required to be given to any union, works council or
similar representative body).

     7.9  Use of Name.  Each Seller agrees, on its own behalf and on behalf of
          -----------
its Subsidiaries and Affiliates, from and after the Closing, not to use any
trademark or name previously or currently used in the NMC Business or the CMS
Business, or any derivation thereof.

                                 ARTICLE VIII

                                INDEMNIFICATION

     8.1  Indemnification by the Sellers.  The Sellers shall jointly and
          ------------------------------
severally indemnify the Buyer in respect of, and hold the Buyer harmless
against, any and all Damages incurred or suffered by the Buyer or any Affiliate
thereof resulting from, relating to, constituting or arising out of:

          (a) any misrepresentation or breach of warranty by either Seller
contained in this Agreement or any of the Ancillary Agreements;

          (b) any failure to perform any covenant or agreement of either Seller
contained in this Agreement or any of the Ancillary Agreements; or

          (c) any Retained Liabilities (including all reasonable fees and
expenses incurred by the Buyer in determining that the underlying claim or
liability is a Retained Liability).

     8.2  Indemnification by the Buyer.  The Buyer shall indemnify the Sellers
          ----------------------------
in respect of, and hold the Sellers harmless against, any and all Damages
incurred or suffered by any of the Sellers or any Affiliate thereof resulting
from, relating to, constituting or arising out of:

          (a) any misrepresentation or breach of warranty by the Buyer contained
in this Agreement or any of the Ancillary Agreements;

          (b) any failure to perform any covenant or agreement of the Buyer
contained in this Agreement or any of the Ancillary Agreements; or

          (c) any Assumed Liabilities (including all reasonable fees and
expenses incurred by the Seller in determining that the underlying claim or
liability is an Assumed Liability).

     8.3  Claims for Indemnification.  Whenever any claim shall arise for
          --------------------------
indemnification hereunder, the Indemnified Party shall promptly notify (in
accordance with Section 10.7) the Indemnifying Party of the claim and, when
known, the facts constituting the basis for such claim; provided, however, that
no delay on the part of the Indemnified Party in notifying the Indemnifying
Party shall relieve the Indemnifying Party from any liability or obligation
hereunder except to the extent of any damage or liability caused by or arising
out of such failure.  In the event of any such claim for indemnification
hereunder resulting from or in connection with any

                                      -43-
<PAGE>

claim or legal proceedings by a third party, the notice to the Indemnifying
Party shall specify, if known, the amount or an estimate of the amount of the
liability arising therefrom. The Indemnified Party shall not settle or
compromise any claim by a third party for which it is seeking indemnification
hereunder without the prior written consent of the Indemnifying Party (which
consent shall not be unreasonably withheld), unless the Indemnifying Party shall
not have taken control of the defense of such claim as provided in Section 8.4
of this Agreement, after notification thereof pursuant to this Section 8.3, in
which case the Indemnified Party may settle or compromise such claim without the
Indemnifying Party's consent.

     8.4  Defense by the Indemnifying Party.
          ---------------------------------

          (a) Subject to Section 8.4(b), in connection with any claim for
indemnification hereunder resulting from or arising out of any claim or legal
proceeding by a third party, the Indemnifying Party at its sole cost and expense
may, upon written notice to the Indemnified Party given within 10 days after the
date of the notice of the claim from the Indemnified Party pursuant to Section
8.3, assume the defense of such claim or legal proceeding with counsel approved
by the Indemnified Party, which approval shall not be unreasonably withheld, if
(i) the Indemnifying Party acknowledges to the Indemnified Party in writing the
Indemnifying Party's obligations to indemnify the Indemnified Party with respect
to all elements of such claim, (ii) the third party seeks monetary damages only,
and (iii) an adverse resolution of the third party's claim would not have a
Material Adverse Effect on the goodwill or the reputation of the Indemnified
Party, the NMC Business or the CMS Business or the future conduct of the
business of the Indemnified Party, the NMC Business or the CMS Business.  If the
Indemnifying Party so assumes such defense, the Indemnified Party shall be
entitled to participate in (but not control) such defense, with its counsel and
at its own expense.  In addition, if the Indemnifying Party so assumes such
defense, it shall take all steps necessary in the defense or settlement thereof.
If the Indemnifying Party does not (or is not permitted under the terms hereof
to) assume the defense of any such claim or legal proceeding, (A) the
Indemnified Party may defend against such claim or legal proceeding (with the
Indemnifying Party responsible for the reasonable fees and expenses of counsel
for the Indemnified Party) in such manner as it may deem appropriate, including
but not limited to settling such claim or legal proceeding on such terms as the
Indemnified Party may deem appropriate, and (B) the Indemnifying Party shall be
entitled to participate in (but not control) the defense of such action, with
its counsel and at its own expense.  The party controlling the defense of a
third party claim pursuant to this Section 8.4 shall keep the other party
advised of the status of such action, suit or proceeding and the defense thereof
and shall consider in good faith recommendations made by the other party with
respect thereto.

                                      -44-
<PAGE>

          (b) If a customer or supplier of the NMC Business or the CMS Business
asserts that the NMC Business, the CMS Business or the Buyer is liable to such
party for a monetary or other obligation which may constitute or result in
Damages for which the Buyer may be entitled to indemnification pursuant to this
Article VIII, and the Buyer reasonably determines that it has a valid business
reason to fulfill such obligation, then (i) the Buyer shall be entitled to
satisfy such obligation, without prior notice to or consent from either of the
Sellers, (ii) the Buyer may make a claim for indemnification pursuant to this
Article VIII in accordance with the provisions hereof, and (iii) the Buyer shall
be reimbursed, in accordance with the provisions hereof, for any such Damages
for which it is entitled to indemnification pursuant to this Article VIII.

     8.5  Payment of Indemnification Obligation.  All indemnification by the
          -------------------------------------
Indemnifying Party hereunder shall be effected promptly as Damages are incurred
by payment of cash, delivery of a cashier's or certified check or wire transfer
of immediately available funds to an account designated by the Indemnified Party
in the amount of the indemnification liability; provided, however, that if the
Indemnifying Party is a Seller, the Buyer, as the Indemnified Party, may, at the
Buyer's election, recover all or any portion of such Damages that are not paid
in cash or by check or wire transfer by setting off against amounts otherwise
due and payable under the Note.

     8.6  Survival.
          --------

          (a) All representations, warranties, covenants and obligations in this
Agreement, the Ancillary Agreements, the Disclosure Schedule, any supplements to
the Disclosure Schedule and any other certificate or documents delivered
pursuant to this Agreement will survive the Closing, and the right to
indemnification, reimbursement or other remedy based on such representations,
warranties, covenants and obligations will not be affected by any investigation
conducted with respect to, or any knowledge acquired (or capable of being
acquired) about the accuracy or inaccuracy of or compliance with, any such
representations, warranty, covenants or obligations.  If the Closing occurs, an
Indemnifying Party will have no liability for indemnification with respect to
any representation or warranty, other than those in Sections 3.1, 3.2, 3.7,
3.14, 4.1 or 4.3 (subject, in the case of Sections 3.7 and 3.14, to applicable
statutes of limitations), unless on or before the first anniversary of the
Closing Date the Indemnifying Party is given notice of a claim pursuant to
Section 8.3 hereof.  However, the preceding sentence of this Section 8.6 will
not apply in any situation in which the Indemnifying Party knew at the time the
representation and warranty was made that it was false.  A claim with respect to
Section 3.7 or Section 3.14 may be made at any time on or before the expiration
date of the

                                      -45-
<PAGE>

applicable statute of limitations. A claim with respect to Sections 3.1, 3.2,
4.1 or 4.3, or a claim for indemnification or reimbursement not based upon any
representation or warranty in Article III or Article IV, may be made at any
time.

          (b) If a notice is given in accordance with Section 8.3 before the
expiration of the applicable survival period (if any) specified in Section
8.6(a), then (notwithstanding the expiration of such time period) the
representation or warranty applicable to such claim shall survive until, but
only for purposes of, the resolution of such claim.

     8.7  Limitations on Amount.  An Indemnifying Party will have no liability
          ---------------------
for indemnification pursuant to Section 8.1(a) or 8.2(a) (or, in the case of
either Seller, as a result of any alleged breach of the obligations set forth in
Section 5.2) until the aggregate Damages to the Indemnified Party exceed
$150,000 (at which point the Indemnified Party shall become liable for only
those aggregate Damages in excess of $150,000).  However, the preceding sentence
of this Section 8.7 will not apply to indemnification arising from any fraud on
the part of the Indemnifying Party and will not apply to any breach of the
representations and warranties set forth in Sections 3.1, 3.2, 3.3(a)(i), 3.7,
4.1, 4.3 or 4.4(a).  For purposes of this Article VIII, all representations and
warranties of the Sellers contained in Article III (other than Section 3.20)
shall be construed as if the term "Material" and any, reference to "Material
Adverse Effect" (and variations thereof) were omitted from such representations
and warranties.

     8.8  Buyer Guaranty.  In the event the Buyer designates a Designated
          --------------
Transferee to buy the Acquired Assets, the Buyer hereby unconditionally
guaranties the due and punctual payment and performance of all of the
obligations of Designated Transferee set forth in this Agreement.  This guaranty
is an irrevocable guaranty of payment (and not just of collection) and shall
continue in effect notwithstanding any extension or modification of the terms of
this Agreement, any assumption of any such guaranteed obligation by any other
party or any other act or event that might otherwise operate as a legal or
equitable discharge of Buyer under this Section 8.8.  This guaranty is in no way
conditioned upon any requirement that either Seller first attempt to collect or
enforce any guaranteed obligation from or against any Designated Transferee.  So
long as any obligation of any Designated Transferee to either Seller under this
Agreement remains unpaid or undischarged, the Buyer hereby waives (but only with
respect to the Sellers and their respective Affiliates and not as to any other
parties) all rights to subrogation arising out of any payment by the Buyer under
this Section 8.8.

     The obligations of the Buyer hereunder shall be absolute and unconditional
irrespective of the validity, legality or enforceability of this Agreement or
any other

                                      -46-
<PAGE>

document related hereto, and shall not be affected by or contingent upon (i) the
liquidation or dissolution of, or the merger or consolidation of any Designated
Transferee with of into any corporation, or any sale or transfer by any
Designated Transferee or all or any part of its property or assets, (ii) the
bankruptcy, receivership, insolvency, reorganization or similar proceedings
involving or affecting any Designated Transferee, (iii) any modification,
alteration, amendment or addition of or to this Agreement, or (iv) any
disability or any other defense of any Designated Transferee or any other person
and any other circumstance whatsoever (with or without notice to or Knowledge of
the Buyer) which may or might in any manner or to any extent vary the risks of
the Buyer or might otherwise constitute a legal or equitable discharge of a
surety or a guarantor or otherwise.

     The Buyer hereby waives all special suretyship defenses and protest, notice
of protest, demand for performance, diligence, notice of any other action at any
time taken or omitted by either Seller and, generally, all demands and notices
of every kind in connection with this Section 8.8 and the obligations of any
Designated Transferee hereby guaranteed, and which Buyer may otherwise assert
against either Seller.

     This Section 8.8 shall continue to be effective or shall be reinstated, as
the case may be, if at any time payment or performance of any of the obligations
of any Designated Transferee under this Agreement is rescinded or must otherwise
be restored any Designated Transferee or returned by the Sellers upon the
insolvency, bankruptcy or reorganization of any Designated Transferee or
otherwise.

     The Buyer acknowledges that each of the waivers set forth above is made
with full knowledge of its significance and consequences and under the
circumstances the waivers are reasonable and not contrary to public policy.  If
any of said waivers is determined to be contrary to any applicable law or public
policy, such waivers shall be effective only to the extent permitted by law.

                                  ARTICLE IX

                                  TERMINATION

<PAGE>

          (b) the Buyer may terminate this Agreement by giving written notice to
the Sellers in the event either Seller is in breach, and either Seller may
terminate this Agreement by giving written notice to the Buyer in the event the
Buyer is in breach, of any material representation, warranty or covenant
contained in this Agreement, which breach is not cured within 15 days of the
receipt of notice by the breaching Party delivered in accordance with the
provisions, of Section 10.7 of this Agreement;

          (c) the Buyer may terminate this Agreement by giving written notice to
the Sellers if the Closing shall not have occurred on or before June 30, 1999 by
reason of the failure of any condition precedent under Section 6.1 hereof
(unless the failure results primarily from a breach by the Buyer of any
representation, warranty or covenant contained in this Agreement); or

          (d) the Sellers may terminate this Agreement by giving written notice
to the Buyer if the Closing shall not have occurred on or before June 30, 1999
by reason of any failure of any condition precedent under Section 6.2 hereof
(unless the failure results primarily from a breach by either Seller of any
representation, warranty or covenant contained in this Agreement).

     9.2  Effect of Termination.  If any party terminates this Agreement
          ---------------------
pursuant to Section 9.1, all obligations of the parties hereunder shall
terminate without any liability of any party to any other party (except for any
liability of any party for breaches of this Agreement, including without
limitation breaches of the covenants set forth in Article V, occurring prior to
such termination).

                                   ARTICLE X

                                 MISCELLANEOUS

is required by Law or Regulation or the applicable rules of a stock exchange;
and provided, further, that the Buyer may issue press releases or make other
public announcements concerning the execution of this Agreement and the terms
thereof with the prior written approval of Renaissance, which approval shall not
be unreasonably withheld or delayed.

     10.2 No Third Party Beneficiaries.  This Agreement (including without

person other than the parties and their respective successors and permitted
assigns.

     10.3 Entire Agreement.  This Agreement (including the documents referred to

Notwithstanding the foregoing, the provisions of the Mutual Non-Disclosure
Agreement, dated April 13, 1999, between the Buyer and Renaissance shall survive
until the Closing, whereupon it shall terminate.

     10.4 Succession and Assignment.  This Agreement shall be binding upon and
          -------------------------
inure to the benefit of the parties named herein and their respective successors
and permitted assigns.  No party may assign either this Agreement or any of its

otherwise, without the prior written approval of the other party, except that
the Buyer may assign some or all of its rights, interests and/or obligations
hereunder to one or more Affiliates of the Buyer (each, a "Designated
Transferee"); provided, however, that such assignment shall be conditioned upon
the guaranty provided in Section 8.8 hereof.  If the Buyer assigns any of its
rights, interests and/or obligations hereunder to one or more Designated
Transferees, then, unless the contract otherwise requires, all references herein
to the Buyer shall mean and include any and all such Designated Transferees.

     10.5 Counterparts.  This Agreement may be executed in one or more
          ------------

                              AMENDED AND RESTATED

                          CERTIFICATE OF INCORPORATION

                                       OF

                                  ZEFER CORP.

     ZEFER Corp. (the "Corporation"), a corporation organized and existing under
and by virtue of the General Corporation Law of Delaware, does hereby certify as
follows:

     1. The Corporation filed its original Certificate of Incorporation with the

Restated Certificate of Incorporation of the Corporation and declaring said
Amended and Restated Certificate of Incorporation advisable. The stockholders of

Incorporation by written consent in accordance with Sections 228, 242 and 245 of
the General Corporation Law of Delaware. The resolution setting forth the
Amended and Restated Certificate of Incorporation is as follows:

RESOLVED:   That the Certificate of Incorporation of the Corporation, as amended

            that the same shall read as follows:

address is The Corporation Trust Company.
<PAGE>

     THIRD. The nature of the business or purposes to be conducted or promoted
by the Corporation is to engage in any lawful act or activity for which
corporations may be organized under the General Corporation Law of Delaware.

     FOURTH. The total number of shares of all classes of stock which the
Corporation shall have authority to issue is 155,000,000 shares, consisting of
(i) 150,000,000 shares of Common Stock, $.001 par value per share ("Common
Stock"), and (ii) 5,000,000 shares of Preferred Stock, $.01 par value per share
("Preferred Stock").

     The following is a statement of the designations and the powers, privileges
and rights, and the qualifications, limitations or restrictions thereof in
respect of each class of capital stock of the Corporation.

A.   COMMON STOCK.
     ------------

     1. General. The voting, dividend and liquidation rights of the holders of
        -------
the Common Stock are subject to and qualified by the rights of the holders of
the Preferred Stock of any series as may be designated by the Board of Directors
upon any issuance of the Preferred Stock of any series.

     2. Voting.  The holders of the Common Stock shall have voting rights at all
        ------
meetings of stockholders, each such holder being entitled to one vote for each
share thereof held by such holder.  There shall be no cumulative voting.

     The number of authorized shares of Common Stock may be increased or
decreased (but not below the number of shares thereof then outstanding) by the
affirmative vote of the holders of a majority of the stock of the Corporation
entitled to vote, irrespective of the provisions of Section 242(b)(2) of the
General Corporation Law of Delaware.

     3. Dividends.  Dividends may be declared and paid on the Common Stock from
        ---------
funds lawfully available therefor as and when determined by the Board of
Directors and subject to any preferential dividend rights of any then
outstanding Preferred Stock.

     4. Liquidation.  Upon the dissolution or liquidation of the Corporation,
        -----------
whether voluntary or involuntary, holders of Common Stock will be entitled to
receive all assets of the Corporation available for distribution to its
stockholders, subject to any preferential rights of any then outstanding
Preferred Stock.

B.   PREFERRED STOCK.
     ---------------

     Preferred Stock may be issued from time to time in one or more series, each
of such series to have such terms as stated or expressed herein and in the
resolution or resolutions providing for the issue of such series adopted by the
Board of Directors of the Corporation as hereinafter provided. Any shares of
Preferred Stock which may be redeemed, purchased or acquired by the Corporation
may be reissued except as otherwise provided by law. Different

                                      -2-
<PAGE>

series of Preferred Stock shall not be construed to constitute different classes
of shares for the purposes of voting by classes unless expressly provided.

     Authority is hereby expressly granted to the Board of Directors from time
to time to issue the Preferred Stock in one or more series, and in connection
with the creation of any such series, by resolution or resolutions providing for
the issuance of the shares thereof, to determine and fix such voting powers,
full or limited, or no voting powers, and such designations, preferences and
relative participating, optional or other special rights, and qualifications,
limitations or restrictions thereof, including without limitation thereof,
dividend rights, conversion rights, redemption privileges and liquidation
preferences, as shall be stated and expressed in such resolutions, all to the
full extent now or hereafter permitted by the General Corporation Law of
Delaware. Without limiting the generality of the foregoing, the resolutions
providing for issuance of any series of Preferred Stock may provide that such
series shall be superior or rank equally or be junior to the Preferred Stock of
any other series to the extent permitted by law. Except as otherwise provided in
this Certificate of Incorporation, no vote of the holders of the Preferred Stock
or Common Stock shall be a prerequisite to the designation or issuance of any
shares of any series of the Preferred Stock authorized by and complying with the
conditions of this Certificate of Incorporation, the right to have such vote
being expressly waived by all present and future holders of the capital stock of
the Corporation.

     FIFTH. Except as otherwise provided herein, the Corporation reserves the
right to amend, alter, change or repeal any provision contained in this
Certificate of Incorporation, in the manner now or hereafter prescribed by
statute and this Certificate of Incorporation, and all rights conferred upon
stockholders herein are granted subject to this reservation.

     SIXTH. In furtherance and not in limitation of the powers conferred upon it
by the laws of the State of Delaware, the Board of Directors shall have the
power to adopt, amend, alter or repeal the Corporation's By-Laws. The
affirmative vote of a majority of the directors present at any regular or
special meeting of the Board of Directors at which a quorum is present shall be
required to adopt, amend, alter or repeal the Corporation's By-Laws. The
Corporation's By-Laws also may be adopted, amended, altered or repealed by the
affirmative vote of the holders of at least sixty-six and two-thirds percent (66
2/3%) of the votes which all the stockholders would be entitled to cast in any
annual election of directors or class of directors. Notwithstanding any other
provisions of law, this Certificate of Incorporation or the By-Laws of the
Corporation, and notwithstanding the fact that a lesser percentage may be
specified by law, the affirmative vote of the holders of at least sixty-six and
two-thirds percent (66 2/3%) of the votes which all the stockholders would be
entitled to cast in any annual election of directors or class of directors shall
be required to amend or repeal, or to adopt any provision inconsistent with,
this Article SIXTH.

     SEVENTH. Except to the extent that the General Corporation Law of Delaware
prohibits the elimination or limitation of liability of directors for breaches
of fiduciary duty, no director of the Corporation shall be personally liable to
the Corporation or its stockholders for monetary damages for any breach of
fiduciary duty as a director, notwithstanding any provision of law imposing such
liability. No amendment to or repeal of this provision shall apply to or have
any

                                      -3-
<PAGE>

effect on the liability or alleged liability of any director of the Corporation
for or with respect to any acts or omissions of such director occurring prior to
such amendment or repeal.

     EIGHTH. 1. Actions, Suits and Proceedings Other than by or in the Right of
                ---------------------------------------------------------------
the Corporation. The Corporation shall indemnify each 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, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Corporation), by
reason of the fact that he is or was, or has agreed to become, a director or
officer of the Corporation, or is or was serving, or has agreed to serve, at the
request of the Corporation, as a director, officer, partner, employee or trustee
of, or in a similar capacity with, another corporation, partnership, joint
venture, trust or other enterprise (including any employee benefit plan) (all
such persons being referred to hereafter as an "Indemnitee"), or by reason of
any action alleged to have been taken or omitted in such capacity, against all
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him or on his behalf in
connection with such action, suit or proceeding and any appeal therefrom, if he
acted in good faith and in a manner he reasonably believed to be in, or not
opposed to, the best interests of the Corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct
was unlawful. The termination of any action, suit or proceeding by judgment,
order, settlement, conviction or upon a plea of nolo contendere or its
                                                ---- ----------
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which he reasonably believed to be in, or not
opposed to, the best interests of the Corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.

     2. Actions or Suits by or in the Right of the Corporation. The Corporation
        ------------------------------------------------------
shall indemnify any Indemnitee who was or is a party or is threatened to be made
a party to any threatened, pending or completed action or suit by or in the
right of the Corporation to procure a judgment in its favor by reason of the
fact that he is or was, or has agreed to become, a director or officer of the
Corporation, or is or was serving, or has agreed to serve, at the request of the
Corporation, as a director, officer, partner, employee or trustee of, or in a
similar capacity with, another corporation, partnership, joint venture, trust or
other enterprise (including any employee benefit plan), or by reason of any
action alleged to have been taken or omitted in such capacity, against all
expenses (including attorneys' fees) and, to the extent permitted by law,
amounts paid in settlement actually and reasonably incurred by him or on his
behalf in connection with such action, suit or proceeding and any appeal
therefrom, if he acted in good faith and in a manner he reasonably believed to
be in, or not opposed to, the best interests of the Corporation, except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the Corporation
unless and only to the extent that the Court of Chancery of Delaware shall
determine upon application that, despite the adjudication of such liability but
in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses (including attorneys' fees)
which the Court of Chancery of Delaware shall deem proper.

     3. Indemnification for Expenses of Successful Party. Notwithstanding the
        ------------------------------------------------
other provisions of this Article, to the extent that an Indemnitee has been
successful, on the merits or

                                      -4-
<PAGE>

otherwise, in defense of any action, suit or proceeding referred to in Sections
1 and 2 of this Article EIGHTH, or in defense of any claim, issue or matter
therein, or on appeal from any such action, suit or proceeding, he shall be
indemnified against all expenses (including attorneys' fees) actually and
reasonably incurred by him or on his behalf in connection therewith. Without
limiting the foregoing, if any action, suit or proceeding is disposed of, on the
merits or otherwise (including a disposition without prejudice), without (i) the
disposition being adverse to the Indemnitee, (ii) an adjudication that the
Indemnitee was liable to the Corporation, (iii) a plea of guilty or nolo
                                                                    ----
contendere by the Indemnitee, (iv) an adjudication that the Indemnitee did not
- ----------
act in good faith and in a manner he reasonably believed to be in or not opposed
to the best interests of the Corporation, and (v) with respect to any criminal
proceeding, an adjudication that the Indemnitee had reasonable cause to believe
his conduct was unlawful, the Indemnitee shall be considered for the purposes
hereof to have been wholly successful with respect thereto.

     4.  Notification and Defense of Claim. As a condition precedent to his
         ---------------------------------
right to be indemnified, the Indemnitee must notify the Corporation in writing
as soon as practicable of any action, suit, proceeding or investigation
involving him for which indemnity will or could be sought. With respect to any
action, suit, proceeding or investigation of which the Corporation is so
notified, the Corporation will be entitled to participate therein at its own
expense and/or to assume the defense thereof at its own expense, with legal
counsel reasonably acceptable to the Indemnitee. After notice from the
Corporation to the Indemnitee of its election so to assume such defense, the
Corporation shall not be liable to the Indemnitee for any legal or other
expenses subsequently incurred by the Indemnitee in connection with such action,
suit, proceeding or investigation, other than as provided below in this Section
4. The Indemnitee shall have the right to employ his own counsel in connection
with such action, suit, proceeding or investigation, but the fees and expenses
of such counsel incurred after notice from the Corporation of its assumption of
the defense thereof shall be at the expense of the Indemnitee unless (i) the
employment of counsel by the Indemnitee has been authorized by the Corporation,
(ii) counsel to the Indemnitee shall have reasonably concluded that there may be
a conflict of interest or position on any significant issue between the
Corporation and the Indemnitee in the conduct of the defense of such action,
suit, proceeding or investigation or (iii) the Corporation shall not in fact
have employed counsel to assume the defense of such action, suit, proceeding or
investigation, in each of which cases the fees and expenses of counsel for the
Indemnitee shall be at the expense of the Corporation, except as otherwise
expressly provided by this Article. The Corporation shall not be entitled,
without the consent of the Indemnitee, to assume the defense of any claim
brought by or in the right of the Corporation or as to which counsel for the
Indemnitee shall have reasonably made the conclusion provided for in clause (ii)
above. The Corporation shall not be required to indemnify the Indemnitee under
this Article for any amounts paid in settlement of any action, suit, proceeding
or investigation effected without its written consent. The Corporation shall not
settle any action, suit, proceeding or investigation in any manner which would
impose any penalty or limitation on the Indemnitee without the Indemnitee's
written consent. Neither the Corporation nor the Indemnitee will unreasonably
withhold or delay its consent to any proposed settlement.

     5. Advance of Expenses. Subject to the provisions of Section 6 of this
        -------------------
Article EIGHTH, in the event that the Corporation does not assume the defense
pursuant to Section 4 of

                                      -5-
<PAGE>

this Article EIGHTH of any action, suit, proceeding or investigation of which
the Corporation receives notice under this Article, any expenses (including
attorneys' fees) incurred by an Indemnitee in defending a civil or criminal
action, suit, proceeding or investigation or any appeal therefrom shall be paid
by the Corporation in advance of the final disposition of such matter; provided,
                                                                       --------
however, that the payment of such expenses incurred by the Indemnitee in advance
- -------
of the final disposition of such matter shall be made only upon receipt of an
undertaking by or on behalf of the Indemnitee to repay all amounts so advanced
in the event that it shall ultimately be determined that the Indemnitee is not
entitled to be indemnified by the Corporation as authorized in this Article; and
further provided that no such advancement of expenses shall be made if it is
determined (in the manner described in Section 6) that (i) the Indemnitee did
not act in good faith and in a manner he reasonably believed to be in, or not
opposed to, the best interests of the Corporation, or (ii) with respect to any
criminal action or proceeding, the Indemnitee had reasonable cause to believe
his conduct was unlawful. Such undertaking shall be accepted without reference
to the financial ability of the Indemnitee to make such repayment.

     6. Procedure for Indemnification.  In order to obtain indemnification or
        -----------------------------
advancement of expenses pursuant to Section 1, 2, 3 or 5 of this Article EIGHTH,
the Indemnitee shall submit to the Corporation a written request, including in
such request such documentation and information as is reasonably available to
the Indemnitee and is reasonably necessary to determine whether and to what
extent the Indemnitee is entitled to indemnification or advancement of expenses.
Any such advancement of expenses shall be made promptly, and in any event within
60 days after receipt by the Corporation of the written request of the
Indemnitee, unless with respect to requests under Section 1, 2 or 5 of this
Article EIGHTH the Corporation determines within such 60-day period that the
Indemnitee did not meet the applicable standard of conduct set forth in Section
1, 2 or 5 of this Article EIGHTH, as the case may be.  Any such indemnification,
unless ordered by a court, shall be made with respect to requests under Section
1 or 2 only as authorized in the specific case upon a determination by the
Corporation that the indemnification of the Indemnitee is proper because the
Indemnitee has met the applicable standard of conduct set forth in Section 1 or
2, as the case may be.  Such determination shall be made in each instance (a) by
a majority vote of the directors of the Corporation consisting of persons who
are not at that time parties to the action, suit or proceeding in question
("disinterested directors"), whether or not a quorum, (b) by a majority vote of
a committee of disinterested directors designated by majority vote of
disinterested directors, whether or not a quorum, (c), if there are no
disinterested directors, or if disinterested directors so direct, by independent
legal counsel (who may, to the extent permitted by law, be regular legal counsel
to the Corporation) in a written opinion, or (d) by the stockholders of the
Corporation.

     7.  Remedies.  The right to indemnification or advances as granted by this
         --------
Article shall be enforceable by the Indemnitee in any court of competent
jurisdiction.  Neither the failure of the Corporation to have made a
determination prior to the commencement of such action that indemnification is
proper in the circumstances because the Indemnitee has met the applicable
standard of conduct, nor an actual determination by the Corporation pursuant to
Section 6 of this Article EIGHTH that the Indemnitee has not met such applicable
standard of conduct, shall be a defense to the action or create a presumption
that the Indemnitee has not met the applicable

                                      -6-
<PAGE>

standard of conduct. The Indemnitee's expenses (including attorneys' fees)
incurred in connection with successfully establishing his right to
indemnification, in whole or in part, in any such proceeding shall also be
indemnified by the Corporation.

     8.  Limitations.  Notwithstanding anything to the contrary in this Article,
         -----------
except as set forth in Section 7 of the Article EIGHTH, the Corporation shall
not indemnify an Indemnitee in connection with a proceeding (or part thereof)
initiated by the Indemnitee unless the initiation thereof was approved by the
Board of Directors of the Corporation.  Notwithstanding anything to the contrary
in this Article, the Corporation shall not indemnify an Indemnitee to the extent
such Indemnitee is reimbursed from the proceeds of insurance, and in the event
the Corporation makes any indemnification payments to an Indemnitee and such
Indemnitee is subsequently reimbursed from the proceeds of insurance, such
Indemnitee shall promptly refund such indemnification payments to the
Corporation to the extent of such insurance reimbursement.

     9.  Subsequent Amendment. No amendment, termination or repeal of this
         --------------------
Article or of the relevant provisions of the General Corporation Law of Delaware
or any other applicable laws shall affect or diminish in any way the rights of
any Indemnitee to indemnification under the provisions hereof with respect to
any action, suit, proceeding or investigation arising out of or relating to any
actions, transactions or facts occurring prior to the final adoption of such
amendment, termination or repeal.

     10. Other Rights. The indemnification and advancement of expenses provided
         ------------
by this Article shall not be deemed exclusive of any other rights to which an
Indemnitee seeking indemnification or advancement of expenses may be entitled
under any law (common or statutory), agreement or vote of stockholders or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in any other capacity while holding office for the Corporation,
and shall continue as to an Indemnitee who has ceased to be a director or
officer, and shall inure to the benefit of the estate, heirs, executors and
administrators of the Indemnitee. Nothing contained in this Article shall be
deemed to prohibit, and the Corporation is specifically authorized to enter
into, agreements with officers and directors providing indemnification rights
and procedures different from those set forth in this Article. In addition, the
Corporation may, to the extent authorized from time to time by its Board of
Directors, grant indemnification rights to other employees or agents of the
Corporation or other persons serving the Corporation and such rights may be
equivalent to, or greater or less than, those set forth in this Article.

     11.  Partial Indemnification. If an Indemnitee is entitled under any
          -----------------------
provision of this Article to indemnification by the Corporation for some or a
portion of the expenses (including attorneys' fees), judgments, fines or amounts
paid in settlement actually and reasonably incurred by him or on his behalf in
connection with any action, suit, proceeding or investigation and any appeal
therefrom but not, however, for the total amount thereof, the Corporation shall
nevertheless indemnify the Indemnitee for the portion of such expenses
(including attorneys' fees), judgments, fines or amounts paid in settlement to
which the Indemnitee is entitled.

     12. Insurance.  The Corporation may purchase and maintain insurance, at its
         ---------
expense, to protect itself and any director, officer, employee or agent of the
Corporation or another

                                      -7-
<PAGE>

corporation, partnership, joint venture, trust or other enterprise (including
any employee benefit plan) against any expense, liability or loss incurred by
him in any such capacity, or arising out of his status as such, whether or not
the Corporation would have the power to indemnify such person against such
expense, liability or loss under the General Corporation Law of Delaware.

     13. Merger or Consolidation. If the Corporation is merged into or

     NINTH. This Article is inserted for the management of the business and for
the conduct of the affairs of the Corporation.

     1.  Number of Directors; Election of Directors. The number of directors of

         --------------------
into three classes: Class I, Class II and Class III. No one class shall have
more than one director more than any other class. If a fraction is contained in

then, if such fraction is one-third, the extra director shall be a member of

<PAGE>

     3.  Terms of Office. Each director shall serve for a term ending on the
         ---------------

serve for a term expiring at the Corporation's annual meeting of stockholders
held in 2001; each initial director in Class II shall serve for a term expiring
at the Corporation's annual meeting of stockholders held in 2002; and each

         ------------------------------------------------------------------
Decreases in the Authorized Number of Directors. In the event of any increase or
- -----------------------------------------------
decrease in the authorized number of directors, (i) each director then serving
as such shall nevertheless continue as a director of the class of which he is a
member until the expiration of his current term, subject to his earlier death,
resignation or removal and (ii) the newly created or eliminated directorships
resulting from such increase or decrease shall be apportioned by the Board of
Directors among the three classes of directors in accordance with the provisions
of Section 2 of this Article NINTH. To the extent possible, consistent with the
provisions of Section 2 of this Article NINTH, any newly created directorships
shall be added to those classes whose terms of office are to expire at the
latest dates following such allocation, and any newly eliminated directorships
shall be subtracted from those classes whose terms of offices are to expire at
the earliest dates following such allocation, unless otherwise provided from
time to time by resolution of the Board of Directors.

     5.  Quorum. A majority of the directors at any time in office shall
         ------
constitute a quorum for the transaction of business. In the event one or more of
the directors shall be disqualified to vote at any meeting, then the required
quorum shall be reduced by one for each director so disqualified, provided that
in no case shall less than one-third of the number of directors fixed pursuant
to Section 1 of this Article NINTH constitute a quorum. If at any meeting of the
Board of Directors there shall be less than such a quorum, a majority of the
directors present may adjourn the meeting from time to time without further
notice other than announcement at the meeting, until a quorum shall be present.

     6.  Action at Meeting. Every act or decision done or made by a majority of
         -----------------
the directors present at a meeting duly held at which a quorum is present shall
be regarded as the act of the Board of Directors unless a greater number is
required by law, by this Certificate of Incorporation, or by the By-Laws of the
Corporation.

     7.  Removal. Directors of the Corporation may be removed only for cause by
         -------
the affirmative vote of the holders of at least a majority of the votes which
all the stockholders would be entitled to cast in any annual election of
directors or class of directors.

     8.  Vacancies.  Any vacancy in the Board of Directors, however occurring,
         ---------
including a vacancy resulting from an enlargement of the Board, shall be filled
only by vote of a majority of the directors then in office, although less than a
quorum, or by a sole remaining director.  A

                                      -9-

to be brought by stockholders before a meeting of stockholders shall be given in

     10. Amendments to Article. Notwithstanding any other provisions of law,
         ---------------------
this Certificate of Incorporation or the By-Laws of the Corporation, and
notwithstanding the fact that a lesser percentage may be specified by law, the
affirmative vote of the holders of at least sixty-six and two-thirds percent (66
2/3%) of the votes which all the stockholders would be entitled to cast in any
annual election of directors or class of directors shall be required to amend or
repeal, or to adopt any provision inconsistent with, this Article NINTH.

     TENTH. Special meetings of stockholders for any purpose or purposes may be
called at any time by the Board of Directors, the Chairman of the Board or the
President, but such special meetings may not be called by any other person or
persons. Business transacted at any special meeting of stockholders shall be
limited to matters relating to the purpose or purposes stated in the notice of
meeting. Notwithstanding any other provision of law, this Certificate of
Incorporation or the By-Laws of the Corporation, and notwithstanding the fact
that a lesser percentage may be specified by law, the affirmative vote of the
holders of at least sixty-six and two-thirds percent (66 2/3%) of the votes
which all the stockholders would be entitled to cast in any annual election of
directors or class of directors shall be required to amend or repeal, or to
adopt any provision inconsistent with, this Article TENTH.

                                 STOCKHOLDERS

     1.1  Place of Meetings.  All meetings of stockholders shall be held at such
          -----------------
place within or without the State of Delaware as may be designated from time to
time by the Board of Directors, the Chairman of the Board or the President or,
if not so designated, at the registered office of the corporation.

     1.2  Annual Meeting.  The annual meeting of stockholders for the election
          --------------
of directors and for the transaction of such other business as may properly be
brought before the meeting shall be held on a date to be fixed by the Board of
Directors, the Chairman of the Board or the President (which date shall not be a
legal holiday in the place where the meeting is to be held) at the time and
place to be fixed by the Board of Directors, the Chairman of the Board or the
President and stated in the notice of the meeting.  If no annual meeting is held
in accordance with the foregoing provisions, the Board of Directors shall cause
the meeting to be held as soon thereafter as is convenient.  If no annual
meeting is held in accordance with the foregoing provisions, a special meeting
may be held in lieu of the annual meeting, and any action taken at that special
meeting shall have the same effect as if it had been taken at the annual
meeting, and in such case all references in these By-Laws to the annual meeting
of the stockholders shall be deemed to refer to such special meeting.

     1.3  Special Meetings.  Special meetings of stockholders for any purpose or
          ----------------
purposes may be called at any time by the Board of Directors, the Chairman of
the Board or the President, but such special meetings may not be called by any
other person or persons.  Business transacted at any special meeting of
stockholders shall be limited to matters relating to the purpose or purposes
stated in the notice of meeting.

     1.4  Notice of Meetings.  Except as otherwise provided by law, written
          ------------------
notice of each meeting of stockholders, whether annual or special, shall be
given not less than 10 nor more than 60 days before the date of the meeting to
each stockholder entitled to vote at such meeting.  The notices of all meetings
shall state the place, date and hour of the meeting.  The notice of a special
meeting shall state, in addition, the purpose or purposes for which the meeting
is called.  If mailed, notice shall be deemed given when deposited in the United
States mail, postage prepaid, directed to the stockholder at such stockholder's
address as it appears on the records of the corporation.

     1.5  Voting List.  The Secretary shall prepare, at least 10 days before
          -----------
every meeting of stockholders, a complete list of the stockholders entitled to
vote at the meeting, arranged in alphabetical order, and showing the address of
each stockholder and the number of shares registered in the name of each
stockholder.  Such list shall be open to the examination of any stockholder, for
any purpose germane to the meeting, during ordinary business hours, for a period
of at least 10 days prior to the meeting, at a place within the city where the
meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified, at the place where the meeting is to be held.
The list shall also be produced and kept at the time and

          ------
Incorporation or these By-Laws, the holders of a majority of the shares of the
capital stock of the corporation issued and outstanding and entitled to vote at
the meeting, present in person or represented by proxy, shall constitute a
quorum for the transaction of business.  A quorum, once established at a
meeting, shall not be broken by the withdrawal of enough votes to leave less
than a quorum.

     1.7  Adjournments.  Any meeting of stockholders may be adjourned from time
          ------------
to time to any other time and to any other place at which a meeting of
stockholders may be held under these By-Laws by the stockholders present or
represented at the meeting and entitled to vote, although less than a quorum,
or, if no stockholder is present, by any officer entitled to preside at or to
act as secretary of such meeting.  It shall not be necessary to notify any
stockholder of any adjournment of less than 30 days if the time and place of the
adjourned meeting are announced at the meeting at which adjournment is taken,
unless after the adjournment a new record date is fixed for the adjourned
meeting.  At the adjourned meeting, the corporation may transact any business
which might have been transacted at the original meeting.

     1.8  Voting and Proxies.  Each stockholder shall have one vote for each
          ------------------
share of stock entitled to vote held of record by such stockholder and a
proportionate vote for each fractional share so held, unless otherwise provided
by law or the Certificate of Incorporation.  Each stockholder of record entitled
to vote at a meeting of stockholders may vote in person or may authorize another
person or persons to vote for him by a proxy executed in writing (or in such
other manner permitted by the General Corporation Law of Delaware) by the
stockholder or his authorized agent and delivered (including by electronic
transmission) to the Secretary of the corporation.  No such proxy shall be voted
upon after three years from the date of its execution, unless the proxy
expressly provides for a longer period.

     1.9  Action at Meeting.  When a quorum is present at any meeting, any
          -----------------
matter to be voted upon by the stockholders at such meeting shall be decided by
the affirmative vote of the holders of a majority of the stock present or
represented and voting on such matter (or if there are two or more classes of
stock entitled to vote as separate classes, then in the case of each such class,
the holders of a majority of the stock of that class present or represented and
voting on such matter), except when a different vote is required by law, the

meeting, any election by stockholders shall be determined by a plurality of the

           ----------------------------------------------
provided in the Certificate of Incorporation, any action required or permitted

consent or consents in writing, setting forth the action so taken, shall be

provision shall state, in lieu of any statement required by such provision

        Re:   Registration Statement on Form S-1
              ----------------------------------

Ladies and Gentlemen:

     This opinion is furnished to you in connection with a Registration
Statement on Form S-1 (File No. 333-94283) (the "Registration Statement") filed
with the Securities and Exchange Commission (the "Commission") under the
Securities Act of 1933, as amended (the "Securities Act"), for the registration
of an aggregate of 4,600,000 shares of Common Stock, $.001 par value per share
(the "Shares"), of ZEFER Corp., a Delaware corporation (the "Company"), of which
(i) 4,000,000 Shares will be issued and sold by the Company; and (ii) the
remaining 600,000 Shares are issuable upon exercise of an over-allotment option
granted by the Company.

     The Shares are to be sold by the Company pursuant to an underwriting
agreement (the "Underwriting Agreement") to be entered into by and among the
Company and Credit Suisse First Boston Corporation, First Union Securities, Inc.
and FleetBoston Robertson Stephens Inc., as representatives of the several
underwriters named in the Underwriting Agreement, the form of which will be
filed as Exhibit 1 to the Registration Statement.

     We are acting as counsel for the Company in connection with the sale by the
Company of the Shares. We have examined signed copies of the Registration
Statement as filed with the Commission. We have also examined and relied upon
the Underwriting Agreement, minutes of meetings of the stockholders and the
Board of Directors of the Company as provided to us by the Company, stock record
books of the Company as provided to us by the Company, the Certificate of
Incorporation and By-Laws of the Company, each as restated and/or amended to
date, and such other documents as we have deemed necessary for purposes of
rendering the opinions hereinafter set forth.

      In our examination of the foregoing documents, we have assumed the
genuineness of all signatures, the authenticity of all documents submitted to us
as originals, the conformity to original documents of all documents submitted to
us as copies, the authenticity of the originals of such latter documents and the
legal competence of all signatories to such documents.

     We assume that the appropriate action will be taken, prior to the offer
and sale of the Shares in accordance with the Underwriting Agreement, to
register and qualify the Shares for sale under all applicable state securities
or "blue sky" laws.

     We express no opinion herein as to the laws of any state or jurisdiction
other than the state laws of the Commonwealth of Massachusetts, the Delaware
General Corporation Law and the federal laws of the United States of America.

     Based upon and subject to the foregoing, we are of the opinion that the
Shares to be issued and sold by the Company have been duly authorized for
issuance and, when such Shares are issued and paid for in accordance with the
terms and conditions of the Underwriting Agreement, such Shares will be validly
issued, fully paid and nonassessable.

     It is understood that this opinion is to be used only in connection with
the offer and sale of the Shares while the Registration Statement is in effect.

     Please note that we are opining only as to the matters expressly set forth
herein, and no opinion should be inferred as to any other matters. This opinion
is based upon currently existing statutes, rules, regulations and judicial
decisions, and we disclaim any obligation to advise you of any change in any of
these sources of law or subsequent legal or factual developments which might
affect any matters or opinions set forth herein.

     We hereby consent to the filing of this opinion with the Commission as an
exhibit to the Registration Statement in accordance with the requirements of
Item 601(b)(5) of Regulation S-K under the Securities Act and to the use of our
name therein and in the related Prospectus under the caption "Legal Matters." In
giving such consent, we do not hereby admit that we are in the category of
persons whose consent is required under Section 7 of the Securities Act or the
rules and regulations of the Commission.

                                            Very truly yours,

interest payable under this Note shall be subject to reduction to the amount not
in excess of the maximum legal amount allowed under the applicable usury laws as
now or hereafter construed by the courts having jurisdiction over such matters.
If the maturity of this Note is accelerated by reason of an election by the
Company resulting from an Event of Default, voluntary prepayment by Maker or
otherwise, then earned interest may never include more than the maximum amount
permitted by law, computed from the date hereof until payment, and any interest
in excess of the maximum amount permitted by law shall be canceled automatically

to Maker or credited on the principal amount of this Note, or if this Note has
been paid, then the excess shall be rebated to Maker.  The aggregate of all
interest (whether designated as interest, service charges, points or otherwise)
contracted for, chargeable, or receivable under this Note shall under no
circumstances exceed the maximum legal rate upon the unpaid principal balance of
this Note remaining unpaid from time to time.  If such interest does exceed the
maximum legal rate, it shall be deemed a mistake and such excess shall be
canceled automatically and, if theretofore paid, rebated to Maker or credited on
the principal amount of this Note, or if this Note has been repaid, then such
excess shall be rebated to Maker.

     8.   Governing Law.  This Note is made under and governed by the internal
          -------------

<PAGE>

1.   Subordination.
     -------------

     The Holder agrees that it will, without payment of additional
consideration, agree to such customary subordination provisions as any holder of
Senior Indebtedness (as defined below) may from time to time request and, the
Holder shall execute and deliver to any holder of Senior Indebtedness (i) any
such instrument as such holder of Senior Indebtedness may request in order to
confirm the subordination of this Note to such Senior Indebtedness upon the
terms so agreed, and (ii) any powers of attorney specifically confirming the
rights of holders of Senior Indebtedness to enforce such subordination and all
such proofs of claim, assignments of claim and other instruments as may be
requested by the holders of Senior Indebtedness or their representatives to
enforce all claims upon or in respect of this Note. "Senior Indebtedness" means
the principal of, and premium, if any, and interest on (i) all indebtedness of
the Company for monies borrowed from banks, trust companies, insurance companies
and other financial institutions, including commercial paper and accounts
receivable sold or assigned by the Company to such institutions, (ii)
obligations of the Company as lessee under capital leases, (iii) principal of,
and premium, if any, and interest on any indebtedness or obligations of others
of the kinds described in (i) and (ii) above assumed or guaranteed in any manner
by the Company, (iv) deferrals, renewals, extensions and refundings of any such
indebtedness of the Company which the Company and the holder this Note may
hereafter from time to time expressly and specifically agree in writing shall
constitute Senior Indebtedness.

2.   Conversion.
     ----------

     (a)  Subject to and in compliance with the provisions of this Section 2,
prior to the payment in full of the principal amount of this Note, the Holder
may convert the outstanding principal amount of this Note, in whole or in part,
into such number of fully paid, nonassessable shares of common stock, $.01 par
value per share ("Common Stock"), of the Company as is determined by dividing
the aggregate principal amount to be so converted by the applicable Conversion
Price (as defined below and as adjusted pursuant to the provision of Section
2(c)).

     (b)  If, prior to May __, 2002, the Company files a registration statement
for an initial public offering, of its Common Stock ("IPO"), the Company shall,
within five business days of the initial filing of such registration statement,
send written notice of such filing (the "Filing Notice") to the Holder. The
Holder shall, within 30 days from the date of receipt of the Filing Notice (but
in any event no later than the printing of the red herring prospectus for the
IPO), determine whether or not it will convert the outstanding principal amount
of this Note, in whole or in part, into shares of Common Stock in accordance
with this Section 2 and shall send an irrevocable, written notice to the Company
of such election (the "Election Notice"). If, upon the expiration of such 30-day
period, the Holder has not elected to convert this

                                      -2-
<PAGE>

Note into shares of Common Stock or has not notified the Company of its
election, the Holder shall forfeit, its right to convert this Note into Common
Stock hereunder. If the Holder has elected to convert this Note into shares of
Common Stock pursuant to this Section 2(a), such conversion shall become
effective immediately prior to the effectiveness of the registration statement
for the IPO.

     (c)  For purposes of this Section 2, the "Conversion Price" at which Common
Stock shall be issuable upon conversion of this Note shall be equal to the
product of (A) the per share price to the public of the Common Stock in the IPO
and (B) .8. The Holder and the Company expressly acknowledge and agree that any
rights under this Section 2 are conditioned upon the closing of the IPO.

     (d)  Surrender of Note and Delivery of Certificates.  When surrendered for
          ----------------------------------------------
conversion this Note shall, unless the shares issuable on conversion are to be
issued in the same name as the name in which this Note is then registered, be
duly endorsed by, or accompanied by instruments of transfer in form satisfactory
to the Company duly executed by, the Holder or his or its duly authorized
attorney. As promptly as practicable after the surrender of this Note for
conversion and the receipt of the Election Notice, the Company shall deliver or
cause to be delivered at its principal executive office to the Holder, or on the
Holder's written order, a certificate or certificates for the number of full
shares issuable upon the conversion of this Note, or portion hereof, in
accordance with the provisions hereof. Such conversion shall be deemed to have
been made at the time this Note shall have been surrendered for conversion and
the Election Notice shall have been received by the Company at its principal
executive office (the "Conversion Date"), and the Holder in whose name any
certificate or certificates for shares of Common Stock shall be issuable upon
such conversion shall be deemed to have become on the Conversion Date the holder
of record of the shares represented thereby. If less than the entire outstanding
principal amount of this Note is being converted, a new Note shall promptly be
delivered to the holder for the unconverted principal balance and shall be of
like tenor as to all terms as the Note surrendered.

     (e)  Adjustment of Conversion Price.
          ------------------------------

          (i)  In case the Company shall:

               (A)  declare a dividend of Common Stock on its Common Stock;

               (B)  subdivide outstanding Common Stock into a larger number of
          shares of Common Stock by reclassification, stock split or otherwise;
          or

                                      -3-
<PAGE>

               (C)  combine outstanding Common Stock into a smaller number of
          shares of Common Stock by reclassification, reverse stock split or
          otherwise, the number of shares of Common Stock issuable upon
          conversion of this Note immediately prior to any such event shall be
          adjusted proportionately so that thereafter the Holder shall be
          entitled to receive upon conversion of this Note the number of shares
          of Common Stock which such Holder would have owned after the happening
          of any of the events described above had this Note been converted
          immediately prior to the happening of such event; provided, however,
          that the Conversion Price shall in no event be reduced to less than
          the par value of the shares issuable upon conversion. An adjustment
          made pursuant to this Section 2(c) shall become effective immediately
          after the record date in the case of a dividend and shall become
          effective immediately after the effective date in the case of a
          subdivision or combination.

          (ii) If, prior to maturity of this Note, the Company shall at any time
consolidate or merge with another corporation (other than a merger or
consolidation in which the Company is the surviving corporation), the Holder
will thereafter be entitled to receive, upon the conversion hereof, the
securities or property to which a holder of the number of shares of Common Stock
then deliverable upon the conversion hereof would have been entitled upon such
consolidation or merger, and the Company shall take such steps in connection
with such consolidation or merger as may be necessary to ensure that the
provisions hereof shall thereafter be applicable, as nearly as reasonably may
be, in relation to any securities or property thereafter deliverable upon the
conversion of this Note.

     (f)  Notice. In case the Company proposes to take any action referred to in
          ------
Section 2(c) above, or to effect the liquidation, dissolution or winding up of
the Company, then the Company shall cause notice thereof to be mailed to the
Holder, at such Holder's address appearing in the Note Register, at least twenty
(20) days prior to the date on which the transfer books of the Company shall
close or a record be taken for such stock dividend or the date when such
reclassification, liquidation, dissolution or winding up shall be effective, as
the case may be.

     (g)  Statement of Adjustment.  Whenever the Conversion Price shall be
          -----------------------
adjusted as provided in Section 2(c) above, the Company shall forthwith file at
each office designated for the conversion of Subordinated Notes, a statement,
signed by the Chairman of the Board, the President, any Vice President, the
Treasurer or Secretary of the Company, showing in reasonable detail the facts
requiring such adjustment and the Conversion Price that will be effective after
such adjustment. The Company shall also cause a notice setting forth any such
adjustment to be sent by mail, first class, postage prepaid, to each record
holder of Subordinated Notes at his or its address appearing on the Note
Register. Where appropriate, such notice may

                                      -4-
<PAGE>

be given in advance and may be included as part of a notice required to be
mailed under the provisions of Section 2(d) hereof.

     (h)  Fractional Shares.  No fractional shares of Common Stock shall be
          -----------------
issuable upon conversion of this Note, but a payment in cash will be made in
respect of any fraction of a share which would otherwise be issuable upon the
surrender of this Note, or portion hereof, for conversion. Such payment shall be
based on the fair market value of the Common Stock at the time of conversion of
this Note, as determined in good faith by the Board of Directors.

     (i)  Accrued Interest. Upon the conversion of this Note, the Company shall
          ----------------
not be required to pay any accrued but unpaid interest on the amount so
converted up to the Conversion Date.

     (j)  Securities Act of 1933.  Upon conversion of this Note, the Holder may
          ----------------------
be required to execute and deliver to the Company an instrument, in form
satisfactory to the Company, representing that the shares issuable upon
conversion hereof are being acquired for investment and not with a view to
distribution within the meaning of the Securities Act of 1933, as amended.

3.   No Prepayment of Principal.  Except as otherwise provided in Section 6(g),
     --------------------------
the principal indebtedness represented by this Note may not be prepaid in whole
or in part, without the prior written consent of the Holder.

4.   Default.
     -------

     Subject to the subordination provisions of Section 1, the entire unpaid
principal of this Note and the interest then accrued on this Note shall become
and be immediately due and payable upon written demand of the Holder, without
any other notice or demand of any kind or any presentment or protest, if any one
of the following events shall occur and be continuing at the time of such
demand, whether voluntarily or involuntarily, or, without limitation, occurring
or brought about by operation of law or pursuant to or in compliance with any
judgment, decree or order of any court or any order, rule or regulation of any
governmental body:

     (a)  if default shall be made in the payment of any installment of
principal of Note, or of any installment of interest on this Note, and if any
such default shall remain unremedied for ten (10) days; or

     (b)  if the Company (i) makes a composition or an assignment for the
benefit of creditors or trust mortgage, (ii) applies for, consents to,
acquiesces in, files a petition seeking or admits (by answer, default or
otherwise) the material allegations of a petition filed against it seeking the
appointment of a trustee, receiver or liquidator, in bankruptcy or otherwise, of
itself or of all or a substantial portion of its

                                      -5-
<PAGE>

assets, or a reorganization, arrangement with creditors or other remedy, relief
or adjudication available to or against a bankrupt, insolvent or debtor under
any bankruptcy or insolvency law or any law affecting the rights of creditors
generally, or (iii) admits in writing its inability to pay its debts generally
as they become due; or

     (c)  if an order for relief shall have been entered by a bankruptcy court
or if a decree, order or judgment shall have been entered adjudging the Company
insolvent, or appointing a receiver, liquidator, custodian or trustee, in
bankruptcy or otherwise, for it or for all or a substantial portion of its
assets, or approving the winding-up or liquidation of its affairs on the grounds
of insolvency or nonpayment of debts, and such order for relief, decree, order
or judgment shall remain undischarged or unstayed for a period of sixty (60)
days; or if any substantial part of the property of the Company is sequestered
or attached and shall not be returned to the possession of the Company or such
subsidiary or released from such attachment within sixty (60) days.

5.   Note Register.
     -------------

     (a)  The Company shall keep at its principal executive office a register
(herein sometimes referred to as the "Note Register"), in which, subject to such
reasonable regulations as it may prescribe, but at its expense (other than
transfer taxes, if any), the Company shall provide for the registration and
transfer of this Note.

     (b)  Whenever this Note shall be surrendered at the principal executive
office of the Company for transfer or exchange, accompanied by a written
instrument of transfer in form reasonably satisfactory to the Company duly
executed by the Holder or his or its attorney duly authorized in writing, the
Company shall execute and deliver in exchange therefor a new Note or Notes, as
may be requested by such Holder, in the same aggregate unpaid principal amount
and payable on the same date as the principal amount of the Note or Notes so
surrendered; each such new Note shall be dated as of the date to which interest
has been paid on the unpaid principal amount of the Note or Notes so surrendered
and shall be in such principal amount and registered in such name or names as
such Holder may designate in writing.

     (c)  Upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of this Note and of indemnity
reasonably satisfactory to it, and upon reimbursement to the Company of all
reasonable expenses incidental thereto, and upon surrender and cancellation of
this Note (in case of mutilation) the Company will make and deliver in lieu of
this Note a new Note of like tenor and unpaid principal amount and dated as of
the date to which interest has been paid on the unpaid principal amount of this
Note in lieu of which such new Note is made and delivered.

9     BANK'S RIGHTS AND REMEDIES
      --------------------------

9.1   Rights and Remedies.

      When an Event of Default occurs and continues Bank may without notice or
demand, do any or all of the following:

      (a) Declare all Obligations immediately due and payable (but if an Event
of Default described in Section 8.5 occurs all Obligations are immediately due
and payable without any action by Bank);

      (b) Stop advancing money or extending credit for Borrower's benefit under
this Agreement or under any other agreement between Borrower and Bank;

      (c) Settle or adjust disputes and claims directly with account debtors for
amounts, on terms and in any order that Bank considers advisable;

      (d) Make any payments and do any acts it considers necessary or reasonable
to protect its security interest in the Collateral.  Borrower will assemble the
Collateral if Bank requires and make it available as Bank designates.  Bank may
enter premises where the Collateral is located, take and maintain possession of
any part of the Collateral, and pay, purchase, contest, or compromise any Lien
which appears to be prior or superior to its security interest and pay all
expenses incurred.  Borrower grants Bank a license to enter and occupy any of
its premises, without charge, to exercise any of Bank's rights or remedies;

      (e) Apply to the Obligations any (i) balances and deposits of Borrower it
holds. or (ii) any amount held by Bank owing to or for the credit or the account
of Borrower;

      (f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for
sale, advertise for sale, and sell the Collateral; and

      (g) Dispose of the Collateral according to the Code.

9.2   Power of Attorney.

      Effective only when an Event of Default occurs and continues, Borrower
irrevocably appoints Bank as its lawful attorney to: (i) endorse Borrower's name
on any checks or other forms of payment or security; (ii) sign Borrowers name on
any invoice or bill of lading for any Account or drafts against account debtors,
(iii) make, settle, and adjust all claims under Borrower's insurance policies;
(iv) settle and adjust disputes and claims about the Accounts directly with
account debtors, for amounts and on terms Bank determines reasonable; and (v)
transfer the Collateral into the name of Bank or a third party as the Code
permits.  Bank may exercise the power of attorney to sign Borrower's name on any
documents necessary to perfect or continue the perfection of any security
interest regardless of whether an Event of Default has occurred.  Bank's
appointment as Borrower's attorney in fact, and all of Bank's rights and powers,
coupled with an interest, are irrevocable until all Obligations have been fully
repaid and performed and Bank's obligation to provide Advances terminates.

9.3   Accounts Collection.

      When an Event of Default occurs and continues, Bank may notify any Person
owing Borrower money of Bank's security interest in the funds and verify the
amount of the Account. Borrower must collect all payments in trust for Bank and,
if requested by Bank, immediately deliver the payments to Bank in the form
received from the account debtor, with proper endorsements for deposit.

                                       11
<PAGE>

9.4   Bank Expenses.

      If Borrower fails to pay any amount or furnish any required proof of
payment to third persons Bank may make all or part of the payment or obtain
insurance policies required in Section 6.5, and take any action under the
policies Bank deems prudent.  Any amounts paid by Bank are Bank Expenses and
immediately due and payable, bearing interest at the then applicable rate and
secured by the Collateral.  No payments by Bank are deemed an agreement to make
similar payments in the future or Bank's waiver of any Event of Default.

9.5   Bank's Liability for Collateral.

      If Bank complies with reasonable banking practices it is not liable for:
(a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral;
(c) any diminution in the value of the Collateral; or (d) any act or default of
any carrier, warehouseman, bailee, or other person. Borrower bears all risk of
loss, damage or destruction of the Collateral.

9.6   Remedies Cumulative.

      Bank's rights and remedies under this Agreement, the Loan Documents, and
all other agreements are cumulative.  Bank has all rights and remedies provided
under the Code, by law, or in equity.  Bank's exercise of one right or remedy is
not an election, and Bank's waiver of any Event of Default is not a continuing
waiver.  Bank's delay is not a waiver, election, or acquiescence. No waiver is
effective unless signed by Bank and then is only effective for the specific
instance and purpose for which it was given.

9.7   Demand Waiver.

      Borrower waives demand, notice of default or dishonor, notice of payment
and nonpayment, notice of any default, nonpayment at maturity, release,
compromise, settlement, extension, or renewal of accounts, documents,
instruments, chattel paper, and guarantees held by Bank on which Borrower is
liable.

          1A.   Exercise Period. The Registered Holder may exercise, in whole or
                ---------------
part, the purchase rights represented by this Warrant at any time and from time
to time after the Date of Issuance hereof and prior to the tenth anniversary

              ---------------
written notice of the expiration of the Exercise Period at least 30 days but not

          1B.   Exercise Procedure.
                ------------------

          (i)   This Warrant shall be deemed to have been exercised when the
Company has received all of the following items (the "Exercise Time"):
                                                      -------------

                (a) a completed Exercise Agreement, as described in Section 1C
     below, executed by the Person exercising all or any portion of the purchase
     rights represented by this Warrant (the "Purchaser");
                                              ---------

                (b) this Warrant; and

                (c) if this Warrant is not registered in the name of the
     Purchaser, an Assignment or Assignments in the form set forth in Exhibit II
                                                                      ----------
     hereto evidencing the assignment of this Warrant to the Purchaser, in which
     case the Registered Holder shall have complied with the provisions set
     forth in Section 7 hereof.

          (ii)  Certificates evidencing the Warrant Shares purchased upon
exercise of all or any portion of this Warrant shall be delivered by the Company
to the Purchaser within five business days after date of the Exercise Time.
Unless this Warrant has expired or all of the purchase rights represented hereby
have been exercised, the Company shall prepare a new Warrant, substantially
identical hereto, representing the rights formerly represented by this Warrant
which have not expired or been exercised and shall, within such five-day period,
deliver such new Warrant to the Person designated for delivery in the Exercise
Agreement.

          (iii) The Warrant Shares issuable upon the exercise of this Warrant
shall be deemed to have been issued to the Purchaser at the Exercise Time, and
the Purchaser shall be deemed for all purposes to have become the record holder
of such Warrant Shares at the Exercise Time.

          (iv)  The issuance of certificates evidencing Warrant Shares upon
exercise of this Warrant shall be made without charge to the Registered Holder
or the Purchaser for any issuance tax in respect thereof or other cost incurred
by the Company in connection with such exercise and the related issuance of
Warrant Shares.  Each Warrant Share issuable upon exercise of this Warrant shall
be fully paid and nonassessable and free from all liens and charges with respect
to the issuance thereof.

                                      -2-
<PAGE>

          (v)    The Company shall not close its books against the transfer of
this Warrant or of any Warrant Share issued or issuable upon the exercise of
this Warrant in any manner which interferes with the timely exercise of this
Warrant. The Company shall from time to time take all such action as may be
necessary to assure that the par value per share of the unissued Warrant Shares
obtainable upon exercise of this Warrant is at all times equal to or less than
the Exercise Price then in effect.

          (vi)   The Company shall assist and cooperate with any Registered
Holder or Purchaser required to make any governmental filings or obtain any
governmental approvals prior to or in connection with any exercise of this
Warrant (including, without limitation, making any filings required to be made
by the Company).

          (vii)  Notwithstanding any other provision hereof, if an exercise of
any portion of this Warrant is to be made in connection with a registered public
offering or the sale of the Company (whether by merger, sale of stock or
otherwise), the exercise of any portion of this Warrant may, at the election of
the holder hereof, be conditioned upon the consummation of the public offering
or the sale of the Company in which case such exercise shall not be deemed to be
effective until the consummation of such transaction.

          (viii) The Company shall at all times reserve and keep available out
of its authorized capital stock the number of shares of its Preferred Stock
issuable upon the exercise of this Warrant solely for the purpose of issuance
upon the exercise of this Warrant.  The Company shall take all such actions as
may be necessary to assure that all such Warrant Shares may be so issued without
violation of any applicable law or governmental regulation or any requirements
of any domestic securities exchange upon which the Warrant Shares may be listed
(except for official notice of issuance which shall be immediately delivered by
the Company upon each such issuance).  The Company shall not take any action
which would cause the number of authorized but unissued shares of its Preferred
Stock to be less than the number of such shares required to be reserved
hereunder for issuance upon exercise of this Warrant.

          1C.   Exercise Agreement.   Upon any exercise of this Warrant, a
                ------------------
completed Exercise Agreement substantially in the form of Exhibit I attached
                                                          ---------
hereto, executed by the Person exercising all or any portion of the purchase
rights represented by this Warrant, shall be delivered to the Company; provided
                                                                       --------
that, if the Warrant Shares are to be issued to a Person other than the Person
whose name this Warrant is registered, the Exercise Agreement shall also state
the name of the Person to whom the certificates evidencing the Warrant Shares
are to be issued; provided further, if the number of Warrant Shares to be issued
                  -------- -------
does not include all the Warrant Shares obtainable hereunder, the Exercise
Agreement shall also state the name of the Person to whom a new Warrant for the
unexercised portion of the rights hereunder is to be delivered.  Such Exercise
Agreement shall be dated the actual date of execution thereof.

          Section 2.  Adjustment of Exercise Price and Number of Shares.  In
                      -------------------------------------------------
order to prevent dilution of the rights granted under this Warrant, the Exercise
Price and the number of Warrant Shares obtainable upon exercise of this Warrant
shall each be subject to adjustment from time to time as provided in this
Section 2.

                                      -3-
<PAGE>

          2A.  Subdivision or Combination of Stock.  If the Company at any time
               -----------------------------------
subdivides (by any stock split, stock dividend, recapitalization or otherwise)
its outstanding shares of Preferred Stock, then the Exercise Price in effect
immediately prior to such subdivision shall be proportionately reduced and the
number of Warrant Shares obtainable upon exercise of this Warrant shall be
proportionately increased.  If the Company at any time combines (by reverse
stock split or otherwise) its outstanding shares of Preferred Stock, then the
Exercise Price in effect immediately prior to such combination shall be
proportionately increased and the number of Warrant Shares obtainable upon
exercise of this Warrant shall be proportionately decreased.

          2B.  Reorganization, Reclassification, Consolidation, Merger or Sale.
               ---------------------------------------------------------------
Any recapitalization, reorganization, reclassification, consolidation, merger,
sale of all or substantially all of the Company's assets or other transaction,
which in each case is effected in such a way that the holders of its outstanding
shares of Preferred Stock are entitled to receive (either directly or upon
subsequent liquidation) stock, securities or assets with respect to or in
exchange for such Preferred Stock, is referred to herein as an "Organic Change."
                                                                --------------
Prior to the consummation of any Organic Change, the Company shall make
appropriate provision (in form and substance satisfactory to the Registered
Holder of this Warrant) to insure that the Registered Holder of this Warrant
shall thereafter have the right to obtain and receive, in lieu of or in addition
to (as the case may be) the Warrant Shares immediately theretofore obtainable
and receivable upon the exercise of this Warrant, such shares of stock,
securities or assets as may be issued or payable with respect to or in exchange
for the number of Warrant Shares immediately theretofore acquirable and
receivable upon exercise of this Warrant had such Organic Change not taken
place.  In any such case, the Company shall make appropriate provision (in form
and substance satisfactory to the Registered Holder of this Warrant) with
respect to the Registered Holder's rights and interests to insure that the
provisions of this Section 2 and Sections 3 and 4 hereof shall thereafter be
applicable to this Warrant (including, without limitation, in the case of any
such consolidation, merger or sale in which the successor entity or purchasing
entity is other than the Company and in which the value of the Warrant Shares as
reflected by the terms of such transaction is less than the Exercise Price in
effect immediately prior to such transaction, an immediate adjustment of the
Exercise Price and a corresponding immediate adjustment in the number of Warrant
Shares obtainable and receivable upon exercise of this Warrant).  The Company
shall not effect any such consolidation, merger or sale, unless prior to the
consummation thereof, the successor entity (if other than the Company) resulting
from consolidation or merger or the entity purchasing such assets assumes by
written instrument (in form and substance satisfactory to the Registered Holder
of this Warrant), the obligation to deliver to the Registered Holder such shares
of stock, securities or assets as, in accordance with the foregoing provisions,
such holder may be entitled to acquire.

          2C.  Certain Events.  If any event occurs of the type contemplated by
               --------------
the provisions of this Section 2 but not expressly provided for by such
provisions, then the Company's board of directors shall make an appropriate
adjustment in the Exercise Price and an appropriate adjustment in the number of
Warrant Shares obtainable upon exercise of this Warrant so as to protect the
rights of the holders of this Warrant; provided that no such adjustment shall
                                       --------
increase the Exercise Price or decrease the number of Warrant Shares obtainable
as otherwise determined pursuant to this Section 2.

          1B.   Exercise Procedure.
                ------------------

          (i)   This Warrant shall be deemed to have been exercised when the
Company has received all of the following items (the "Exercise Time"):
                                                      -------------

                (a)  a completed Exercise Agreement, as described in Section 1C
     below, executed by the Person exercising all or any portion of the purchase
     rights represented by this Warrant (the "Purchaser");

                (b)  this Warrant; and

                (c)  if this Warrant is not registered in the name of the
     Purchaser, an Assignment or Assignments in the form set forth in Exhibit II
                                                                      ----------
     hereto evidencing the assignment of this Warrant to the Purchaser, in which
     case the Registered Holder shall have complied with the provisions set
     forth in Section 7 hereof.

          (ii)  Certificates evidencing the Warrant Shares purchased upon
exercise of all or any portion of this Warrant shall be delivered by the Company
to the Purchaser within five business days after date of the Exercise Time.
Unless this Warrant has expired or all of the purchase rights represented hereby
have been exercised, the Company shall prepare a new Warrant, substantially
identical hereto, representing the rights formerly represented by this Warrant
which have not expired or been exercised and shall, within such five-day period,
deliver such new Warrant to the Person designated for delivery in the Exercise
Agreement.

          (iii) The Warrant Shares issuable upon the exercise of this Warrant
shall be deemed to have been issued to the Purchaser at the Exercise Time, and
the Purchaser shall be deemed for all purposes to have become the record holder
of such Warrant Shares at the Exercise Time.

          (iv)  The issuance of certificates evidencing Warrant Shares upon
exercise of this Warrant shall be made without charge to the Registered Holder
or the Purchaser for any issuance tax in respect thereof or other cost incurred
by the Company in connection with such exercise and the related issuance of
Warrant Shares.  Each Warrant Share issuable upon exercise of this Warrant shall

be fully paid and nonassessable and free from all liens and charges with respect
to the issuance thereof.

          (v)    The Company shall not close its books against the transfer of
this Warrant or of any Warrant Share issued or issuable upon the exercise of
this Warrant in any manner which interferes with the timely exercise of this
Warrant. The Company shall from time to time take all such action as may be
necessary to assure that the par value per share of the unissued Warrant Shares
obtainable upon exercise of this Warrant is at all times equal to or less than
the Exercise Price then in effect.

          (vi)   The Company shall assist and cooperate with any Registered
Holder or Purchaser required to make any governmental filings or obtain any
governmental approvals prior to or in connection with any exercise of this
Warrant (including, without limitation, making any filings required to be made
by the Company).

          (vii)  Notwithstanding any other provision hereof, if an exercise of
any portion of this Warrant is to be made in connection with a registered public
offering or the sale of the Company (whether by merger, sale of stock or
otherwise), the exercise of any portion of this Warrant may, at the election of
the holder hereof, be conditioned upon the consummation of the public offering
or the sale of the Company in which case such exercise shall not be deemed to be
effective until the consummation of such transaction.

          (viii) The Company shall at all times reserve and keep available out
of its authorized capital stock the number of shares of its Common Stock
issuable upon the exercise of this Warrant solely for the purpose of issuance
upon the exercise of this Warrant. The Company shall take all such actions as
may be necessary to assure that all such Warrant Shares may be so issued without
violation of any applicable law or governmental regulation or any requirements
of any domestic securities exchange upon which the Warrant Shares may be listed
(except for official notice of issuance which shall be immediately delivered by
the Company upon each such issuance). The Company shall not take any action
which would cause the number of authorized but unissued shares of its Common
Stock to be less than the number of such shares required to be reserved
hereunder for issuance upon exercise of this Warrant.

               1C.  Exercise Agreement.   Upon any exercise of this Warrant, a
                    ------------------
completed Exercise Agreement substantially in the form of Exhibit I attached
                                                          ---------

rights represented by this Warrant, shall be delivered to the Company; provided

that, if the Warrant Shares are to be issued to a Person other than the Person
whose name this Warrant is registered, the Exercise Agreement shall also state
the name of the Person to whom the certificates evidencing the Warrant Shares
are to be issued; provided further, if the number of Warrant Shares to be issued
                  -------- -------
does not include all the Warrant Shares obtainable hereunder, the Exercise
Agreement shall also state the name of the Person to whom a new Warrant for the
unexercised portion of the rights hereunder is to be delivered.  Such Exercise
Agreement shall be dated the actual date of execution thereof.

          Section 2.  Adjustment of Exercise Price and Number of Shares.  In
                      -------------------------------------------------
order to prevent dilution of the rights granted under this Warrant, the Exercise
Price and the number of Warrant Shares obtainable upon exercise of this Warrant
shall each be subject to adjustment from time to time as provided in this
Section 2.

               -----------------------------------
subdivides (by any stock split, stock dividend, recapitalization or otherwise)
its outstanding shares of Common Stock, then the Exercise Price in effect
immediately prior to such subdivision shall be proportionately reduced and the
number of Warrant Shares obtainable upon exercise of this Warrant shall be
proportionately increased.  If the Company at any time combines (by reverse
stock split or otherwise) its outstanding shares of Common Stock, then the
Exercise Price in effect immediately prior to such combination shall be
proportionately increased and the number of Warrant Shares obtainable upon
exercise of this Warrant shall be proportionately decreased.

          2B.  Reorganization, Reclassification, Consolidation, Merger or Sale.
               ---------------------------------------------------------------
Any recapitalization, reorganization, reclassification, consolidation, merger,
sale of all or substantially all of the Company's assets or other transaction,
which in each case is effected in such a way that the holders of its outstanding
shares of Common Stock are entitled to receive (either directly or upon
subsequent liquidation) stock, securities or assets with respect to or in
exchange for such Common Stock, is referred to herein as an "Organic Change."
                                                             --------------
Prior to the consummation of any Organic Change, the Company shall make
appropriate provision (in form and substance satisfactory to the Registered
Holder of this Warrant) to insure that the Registered Holder of this Warrant
shall thereafter have the right to obtain and receive, in lieu of or in addition
to (as the case may be) the Warrant Shares immediately theretofore obtainable
and receivable upon the exercise of this Warrant, such shares of stock,
securities or assets as may be issued or payable with respect to or in exchange
for the number of Warrant Shares immediately theretofore acquirable and
receivable upon exercise of this Warrant had such Organic Change not taken
place.  In any such case, the Company shall make appropriate provision (in form
and substance satisfactory to the Registered Holder of this Warrant) with
respect to the Registered Holder's rights and interests to insure that the
provisions of this Section 2 and Sections 3 and 4 hereof shall thereafter be
applicable to this Warrant (including, without limitation, in the case of any
such consolidation, merger or sale in which the successor entity or purchasing
entity is other than the Company and in which the value of the Warrant Shares as
reflected by the terms of such transaction is less than the Exercise Price in
effect immediately prior to such transaction, an immediate adjustment of the
Exercise Price and a corresponding immediate adjustment in the number of Warrant
Shares obtainable and receivable upon exercise of this Warrant).  The Company
shall not effect any such consolidation, merger or sale, unless prior to the
consummation thereof, the successor entity (if other than the Company) resulting
from consolidation or merger or the entity purchasing such assets assumes by
written instrument (in form and substance satisfactory to the Registered Holder
of this Warrant), the obligation to deliver to the Registered Holder such shares
of stock, securities or assets as, in accordance with the foregoing provisions,
such holder may be entitled to acquire.

          2C.  Certain Events.  If any event occurs of the type contemplated by
               --------------
the provisions of this Section 2 but not expressly provided for by such
provisions, then the Company's

                                      -4-
<PAGE>

board of directors shall make an appropriate adjustment in the Exercise Price
and an appropriate adjustment in the number of Warrant Shares obtainable upon
exercise of this Warrant so as to protect the rights of the holders of this
Warrant; provided that no such adjustment shall increase the Exercise Price or
         --------
decrease the number of Warrant Shares obtainable as otherwise determined
pursuant to this Section 2.


          2D.  Notices.
               -------

          (i)  Immediately upon any adjustment of the Exercise Price, the
Company shall give written notice thereof to the Registered Holder, setting
forth in reasonable detail and certifying the calculation of such adjustment.

Holder at least 20 days prior to the date on which the Company closes its books

the Common Stock or (C) for determining rights to vote with respect to any
Organic Change, dissolution or liquidation.  The Company shall also give written
notice to the Registered Holder at least 20 days prior to the date on which any
Organic Change, dissolution or liquidation shall take place.

          Section 3.  Liquidating Dividends.  If the Company declares or pays a
                      ---------------------
dividend upon the Common Stock payable otherwise than in cash out of earnings or
earned surplus (determined in accordance with generally accepted accounting
principles, consistently applied) except for a stock dividend payable in shares
of Common Stock (a "Liquidating Dividend"), then the Company shall pay to the
                    --------------------
Registered Holder of this Warrant at the time of payment thereof the Liquidating
Dividend which would have been paid to the Registered Holder on the Warrant
Shares had this Warrant been fully exercised immediately prior to the date on
which the record was taken for such Liquidating Dividend or, if no record was
taken, the date as of which the record holders of Common Stock entitled to such
dividends are to be determined.

          Section 4.  Purchase Rights.  If at any time the Company grants,
                      ---------------
issues or sells any Options, Convertible Securities or rights to purchase stock,
warrants, securities or other property pro rata to the record holders of its
shares of Common Stock (the "Purchase Rights"), then the Registered Holder of
                             ---------------
this Warrant shall be entitled to acquire, upon the terms applicable to such
Purchase Rights, the aggregate Purchase Rights which such holder could have
acquired if such holder had held the number of Warrant Shares obtainable upon
complete exercise of this Warrant immediately before the date on which the
record is taken for the grant, issuance or sale of such Purchase Rights or, if
no such record is taken, the date as of which the record holders of its shares
of Common Stock are to be determined for the grant, issue or sale of such
Purchase Rights.

                             ------------------
detail the identity of the prospective transferee(s) and the terms and
conditions of the Transfer.  The Other Stockholders may elect to participate in

of Stockholder Shares to be sold in the contemplated Transfer.

          (b)  GTCR will use reasonable best efforts to obtain the agreement of
the prospective transferee(s) to the participation of the Other Stockholders in
any contemplated Transfer, and GTCR will not transfer any of its Stockholder
Shares to the prospective transferee(s) unless (A) the prospective transferee(s)

          (c)  Notwithstanding anything to the contrary in any other provision
of this Agreement, the restrictions set forth in this Section 3 shall not apply

transferees will deliver a written notice to the Company, which notice will
disclose in reasonable detail the identity of such transferee.

          (d)  The provisions of this Section 3 will terminate upon the first to
                                      ---------
occur of (i) the consummation of a Sale of the Company and (ii) the consummation
of a Public Offering.

          4.   First Refusal Rights.
               --------------------

          (a)  Prior to making any Transfer of Stockholder Shares (other than a
Transfer pursuant to a Public Sale of the type referred to in clause (i) of the
definition thereof or a Sale of the Company), any Stockholder (other than the
Investors) desiring to make such Transfer (the "Transferring Stockholder") will
                                                ------------------------
give written notice (the "Sale Notice") to the Company, the Executives and the
                          -----------
Investors (each a "Sale Notice Recipient", and collectively, the "Sale Notice
                   ---------------------                          -----------
Recipients").  The Sale Notice will disclose in reasonable detail the identity
- ----------
of the prospective transferee(s), the number of shares to be transferred and the
terms and conditions of the proposed transfer.  Such Transferring Stockholder
will not consummate any Transfer until 45 days after the Sale Notice has been
given to the Sale Notice Recipients, unless the parties to the Transfer have
been finally determined pursuant to this Section 4 prior to the expiration of
                                         ---------
such 45-day period.  (The date of the first to occur of such events is referred
to herein as the "Authorization Date").
                  ------------------

          (b)  The Company may elect to purchase all (but not less than all) of
such Stockholder Shares to be transferred upon the same terms and conditions as
those set forth in the Sale Notice by delivering a written notice of such
election to the Executives and the Investors (individually, an "Other Sale
                                                                ----------
Notice Recipient", and collectively, the "Other Sale Notice Recipients") and to
- ----------------                          ----------------------------
the Transferring Stockholder within 20 days after the Sale Notice has been given
to the Company.  If the Company has not elected to purchase all of the
Stockholder Shares to be transferred, the Other Sale Notice Recipients may elect
to purchase all (but not less than all) of the Stockholder Shares to be
transferred upon the same terms and conditions as those set forth in the Sale
Notice by giving written notice of such election to such Transferring
Stockholder within 25 days after the Sale Notice has been given to GTCR.  If
more than one Other Sale Notice Recipient elects to purchase the Stockholder
Shares to be transferred, the shares of Stockholder Shares to be sold shall be
allocated among the Other Sale Notice Recipients pro rata according to the
number of shares of Common Stock owned by each Other Sale Notice Recipient on a
fully diluted basis.  If neither the Company nor the Other Sale Notice
Recipients elects to purchase all of the Stockholder Shares specified in the
Sale Notice, the Transferring Stockholder may transfer the Stockholder Shares
specified in the Sale Notice at a price and on terms no more favorable to the
transferee(s) thereof than specified in the Sale Notice during the 60-day period
immediately following the Authorization Date.  Any Stockholder Shares not
transferred within such 60-day period will be subject to the provisions of this
Section 4 upon subsequent transfer.  The Company may pay the purchase price for
- ---------

                                      -4-
<PAGE>

such shares by offsetting amounts outstanding under any bona fide debts owed by
the Transferring Stockholder to the Company.

          (c)  The restrictions of this Section 4 will not apply with respect to
                                        ---------
(i) any Transfer of Stockholder Shares by any Stockholder to or among its
Affiliates, (ii) any Transfer of Stockholder Shares by or to any Investor, (iii)
a repurchase of Stockholder Shares by the Company pursuant to the terms of the
Management Agreements (as defined in the Purchase Agreement), (iv) a Public
Sale, or (v) an Approved Sale (as defined in Section 5(a)); provided that the
                                             -------------  --------
restrictions contained in this Agreement will continue to be applicable to the
Stockholder Shares after any Transfer pursuant to clause (i) or (ii) above and
the transferee of such Stockholder Shares shall agree in writing to be bound by
the provisions of this Agreement.  Upon the Transfer of Stockholder Shares
pursuant to clause (i) or (ii) of the previous sentence, the transferees will
deliver a written notice to the Company, which notice will disclose in
reasonable detail the identity of such transferee.

          (d)  Notwithstanding anything herein to the contrary, except pursuant
to clause (c) above, in no event shall any Transfer of Stockholder Shares
pursuant to this Section 4 be made for any consideration other than cash payable
                 ---------
upon consummation of such Transfer.

          (e)  The restrictions set forth in this Section 4 shall continue with
                                                  ---------
respect to each Stockholder Share until the earlier of (i) the date on which
such Share has been transferred in a Public Sale, (ii) the consummation of an
Approved Sale, and (iii) the date on which such Stockholder Share has been
transferred pursuant to this Section 4 (other than Section 4(c)).
                             ---------             ------------

          5.   Sale of the Company.
               -------------------

          (a)  If the holders of a majority of the shares of Common Stock then
outstanding approve a Sale of the Company (an "Approved Sale"), each holder of
                                               -------------
Common Stock shall vote for, consent to and raise no objections against such
Approved Sale.  If the Approved Sale is structured as a (i) merger or
consolidation, each holder of Common Stock shall waive any dissenters' rights,
appraisal rights or similar rights in connection with such merger or
consolidation or (ii) sale of stock, each holder of Common Stock shall agree to
sell all of his Common Stock and rights to acquire Common Stock on the terms and
conditions approved by the Board and the holders of a majority of the Common
Stock (voting as a single class) then outstanding. Each holder of Common Stock
shall take all necessary or desirable actions in connection with the
consummation of the Approved Sale as requested by the Company.

          (b)  The obligations of the holders of Common Stock with respect to
the Approved Sale of the Company are subject to the satisfaction of the
following conditions: (i) upon the consummation of the Approved Sale, each
holder of Common Stock shall receive the same form of consideration and the same
amount of consideration per share, and each holder of Class A Preferred shall
receive consideration not in excess of the aggregate Liquidation Value (as
defined in the Company's Certificate of Incorporation as of the date hereof) of
all shares of Class A Preferred held by such holder (plus all accrued and unpaid
dividends thereon); (ii) if any holders of a class of Common Stock are given an
option as to the form and amount of consideration to be received, each holder of
such class of Common Stock shall be given the same option; and (iii) each holder
of then

                                      -5-
<PAGE>

currently exercisable rights to acquire shares of a class of Common Stock
shall be given an opportunity to either (A) exercise such rights prior to the
consummation of the Approved Sale and participate in such sale as holders of
such class of Common Stock or (B) upon the consummation of the Approved Sale,
receive in exchange for such rights consideration equal to the amount determined
by multiplying (1) the same amount of consideration per share of a class of
Common Stock received by holders of such class of Common Stock in connection
with the Approved Sale less the exercise price per share of such class of Common
Stock of such rights to acquire such class of Common Stock by (2) the number of
shares of such class of Common Stock represented by such rights.

          (c)  If either the Company or the holders of the Common Stock or the
Class A Preferred enter into an negotiation or transaction for which Rule 506
(or any similar rule then in effect) promulgated by the Securities and Exchange
Commission may be available with respect to such negotiation or transaction
(including a merger, consolidation or other reorganization), the holders of
Stockholder Shares will, at the request of the Company, appoint a purchaser
representative (as such term is defined in Rule 501) reasonably acceptable to
the Company.  If any holder of Stockholder Shares appoints a purchaser
representative designated by the Company, the Company will pay the fees of such
purchaser representative, but if any holder of Stockholder Shares declines to
appoint the purchaser representative designated by the Company such holder will
appoint another purchaser representative, and such holder will be responsible
for the fees of the purchaser representative so appointed.

          (d)  Holders of Stockholder Shares will bear their pro rata share
(based upon the number of shares sold) of the costs of any sale of such
Stockholder Shares pursuant to an Approved Sale to the extent such costs are
incurred for the benefit of all holders of Stockholder Shares and are not
otherwise paid by the Company or the acquiring party.  For purposes of this
Section 5(d), costs incurred in exercising reasonable efforts to take all
- ------------
actions in connection with the consummation of an Approved Sale in accordance
with Section 5(a) shall be deemed to be for the benefit of all holders of the
     ------------
Stockholder Shares.  Costs incurred by holders of Stockholder Shares on their
own behalf will not be considered costs of the transaction hereunder.

          6.   Public Offering.  In the event that the Board or the holders of a
               ---------------
majority of the Investor Registrable Securities (as defined in the Registration
Agreement, dated March 23, 1999, by and among the Company, the Investors and
certain other stockholders) (collectively, the "Approving Persons") approves an
                                                -----------------
initial Public Offering, the holders of Stockholder Shares shall take all
necessary or desirable actions requested by the Approving Persons in connection
with the consummation of such Public Offering, including without limitation
compliance with the requirements of all laws and regulatory bodies which are
applicable or which have jurisdiction over such Public Offering.  In the event
that such Public Offering is an underwritten offering and the managing
underwriters advise the Company in writing that in their opinion the Company's
capital structure would adversely affect the marketability of the offering, each
holder of Stockholder Shares shall consent to and vote for a recapitalization,
reorganization or exchange (each, a "Recapitalization") of any class of the
                                     ----------------
Company's capital stock into securities that the managing underwriters and the
Approving Persons find acceptable and shall take all necessary and desirable
actions in connection with the consummation of such Recapitalization; provided
                                                                      --------
that, each holder

of Common Stock shall receive the same type of security with the same value per
share, and each holder of Class A Preferred shall receive the same type of
security with the same value per share; provided further, that the aggregate
value of the securities issued to the holders of Class A Preferred shall not
exceed the aggregate Liquidation Value of such Class A Preferred (plus all
accrued and unpaid dividends thereon) or the number of shares of Common Stock
equal to (i) the aggregate Liquidation Value of such Class A Preferred (plus all
accrued and unpaid dividends thereon), divided by (ii) the price per
                                       ------- --

                               ---------

     The parties hereto agree as follows:

     1.   Demand Registrations.
          --------------------

          (a)  Requests for Registration. At any time, the holders of a
               -------------------------
majority of the Investor Registrable Securities may request registration under
the Securities Act of all or any portion of their Registrable Securities having
an aggregate offering price of at least $5,000,000 (based on the then current
market price or fair value at the time of such request) on Form S- 1 or any
similar long-form registration ("Long-Form Registrations"), or on Form S-2 or S-
                                 -----------------------
3 or any similar short-form registration ("Short-Form Registrations") if
                                           ------------------------
available.  All registrations requested pursuant to this Section 1(a) are
                                                         ------------
referred to herein as "Demand Registrations".  Each request for a Demand
                       --------------------
Registration shall specify the approximate number of Registrable Securities
requested to be registered and the anticipated per share price range for such
offering.  Within ten days after receipt of any such request, the Company shall
give written notice of such requested registration to all other holders of
Registrable Securities and shall include in such registration all Registrable
Securities with respect to which the Company has received written requests for
inclusion therein within 15 days after the receipt of the Company's notice.

          (b)  Investor Long-Form Registrations.  The holders of Investor
               --------------------------------
Registrable Securities shall be entitled to request an unlimited number of Long-
Form Registrations in which the Company shall pay all Registration Expenses (as
defined in Section 5) ("Company-paid Long-Form Registrations").  All Long-Form
           ---------    ------------------------------------
Registrations shall be underwritten registrations.

                                                                  EXECUTION COPY
                                                                  --------------

          (c)  Investor Short-Form Registrations.  In addition to the Long-Form
               ---------------------------------
Registrations provided pursuant to Section 1 (b), the holders of Investor
                                   ----------
Registrable Securities shall be entitled to request an unlimited number of
Short-Form Registrations in which the Company shall pay all Registration
Expenses.  Demand Registrations shall be Short-Form Registrations whenever the
Company is permitted to use any applicable short form.  After the Company has
become subject to the reporting requirements of the Securities Exchange Act, the
Company shall use its best efforts to make Short-Form Registrations on Form S-3
available for the sale of Registrable Securities.

          (d)  Priority on Demand Registration.  The Company shall not include
               -------------------------------
in any Demand Registration any securities which are not Registrable Securities
without the prior written consent of the holders of a majority of the
Registrable Securities included in such registration. If a Demand Registration
is an underwritten offering and the managing underwriters advise the Company in
writing that in their opinion the number of Registrable Securities and, if
permitted hereunder, other securities requested to be included in such offering
exceeds the number of Registrable Securities and other securities, if any, which
can be sold in an orderly manner in such offering within a price range
acceptable to the holders of a majority of the Registrable Securities to be
included in such registration therein, the Company shall include in such
registration prior to the inclusion of any securities which are not Registrable
Securities the number of Registrable Securities requested to be included which
in the opinion of such underwriters can be sold in an orderly manner within the
price range of such offering, pro rata among the respective holders thereof on
the basis of the amount of Registrable Securities owned by each such holder.

          (e)  Restrictions on Long-Form Registrations. The Company shall not be
               ---------------------------------------
obligated to effect any Long-Form Registration within 90 days after the
effective date of a previous Long-Form Registration or a previous registration
in which the holders of Registrable Securities were given piggyback rights
pursuant to Section 2 and in which there was no reduction in the number of
            ---------
Registrable Securities requested to be included.  The Company may postpone for
up to 180 days the filing or the effectiveness of a registration statement for a
Demand Registration if the Company and the holders of a majority of the
Registrable Securities agree that such Demand Registration would reasonably be
expected to have a material adverse effect on any proposal or plan by the
Company or any of its Subsidiaries to engage in any acquisition of assets (other
than in the ordinary course of business) or any merger, consolidation, tender
offer, reorganization or similar transaction; provided however, that in such
                                              -------- -------
event, the holders of Registrable Securities initially requesting such Demand
Registration shall be entitled to withdraw such request and the Company shall
pay all Registration Expenses in connection with such registration.  The Company
may delay a Demand Registration hereunder only once in any twelve-month period.

          (f)  Selection of Underwriters.  The holders of a majority of the
               -------------------------
Registrable Securities included in any Demand Registration shall have the right
to select the investment banker(s) and manager(s) to administer the offering.

          (g)  Other Registration Rights.  Except as provided in this Agreement,
               -------------------------
the Company shall not grant to any Persons the right to request the Company to
register any equity securities of the Company, or any securities convertible or
exchangeable into or exercisable for

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

such securities, without the prior written consent of the holders of a majority
of the Registrable Securities.

     2.   Piggyback Registrations.
          -----------------------

          (a)  Right to Piggyback. Whenever the Company proposes to register any
               ------------------
of its securities under the Securities Act (other than (i) pursuant to a Demand
Registration, (ii) in connection with an initial public offering of the
Company's equity securities, or (iii) in connection with registrations on form
S-8 or any successor form) and the registration form to be used may be used for
the registration of Registrable Securities (a "Piggyback Registration"), the
                                               ----------------------
Company shall give prompt written notice to all holders of Registrable
Securities of its intention to effect such a registration and shall include in
such registration all Registrable Securities with respect to which the Company
has received written requests for inclusion therein within 20 days after the
receipt of the Company's notice.

          (b)  Piggyback Expenses.  The Registration Expenses of the holders of
               ------------------
Registrable Securities shall be paid by the Company in all Piggyback
Registrations.

          (c)  Priority on Primary Registrations. If a Piggyback Registration is
               ---------------------------------
an underwritten primary registration on behalf of the Company, and the managing
underwriters advise the Company in writing that in their opinion the number of
securities requested to be included in such registration exceeds the number
which can be sold in an orderly manner in such offering within a price range
acceptable to the Company, the Company shall include in such registration (i)
first, the securities the Company proposes to sell, (ii) second, the Registrable
Securities requested to be included in such registration, pro rata among the
holders of such Registrable Securities on the basis of the number of shares
owned by each such holder, and (iii) third, other securities requested to be
included in such registration.

          (d)  Priority on Secondary Registrations.  If a Piggyback Registration
               -----------------------------------
is an underwritten secondary registration on behalf of holders of the Company's
securities (other than holders of Registrable Securities; it being understood
that secondary registrations on behalf of holders of Registrable Securities are
addressed in Section I above rather than this Section 2(d)), and the managing
             ---------
underwriters advise the Company in writing that in their opinion the number of
securities requested to be included in such registration exceeds the number
which can be sold in an orderly manner in such offering within a price range
acceptable to the holders of a majority of the Registrable Securities to be
included in such registration, the Company shall include in such registration
(i) first, the securities requested to be included therein by the holders
requesting such registration, (ii) second, the Registrable Securities requested
to be included in such registration, pro rata among the holders of such
Registrable Securities on the basis of the number of shares owned by each such
holder, and (iii) third, other securities requested to be included in such
registration.

          (e)  Selection of Underwriters.  If any Piggyback Registration is an
               -------------------------
underwritten offering, the selection of investment banker(s) and manager(s) for
the offering must be approved by the holders of a majority of the Registrable
Securities included in such Piggyback Registration.  Such approval shall not be
unreasonably withheld.

          (f)  Other Registrations.  If the Company has previously filed a
               -------------------
registration statement with respect to Registrable Securities pursuant to
Section 1 or pursuant to this Section 2, and if such previous registration has
- ---------                     ---------
not been withdrawn or abandoned, the Company shall not file or cause to be
effected any other registration of any of its equity securities or securities
convertible or exchangeable into or exercisable for its equity securities under
the Securities Act (except on Form S-8 or any successor form), whether on its
own behalf or at the request of any holder or holders of such securities, until
a period of at least 180 days has elapsed from the effective date of such
previous registration.

     3.   Holdback Agreements,
          -------------------

          (a)  Each holder of Registrable Securities and each officer and
director of the Company shall not effect any public sale or distribution
(including sales pursuant to Rule 144) of equity securities of the Company, or
any securities convertible into or exchangeable or exercisable for such
securities, during the seven days prior to and the 180-day period beginning on
the effective date of any underwritten Demand Registration, any underwritten
Piggyback Registration in which Registrable Securities are included (except as
part of such underwritten registration), or the initial public offering, unless
the underwriters managing the registered public offering otherwise agree.

          (b)  The Company (i) shall not effect any public sale or distribution
of its equity securities, or any securities convertible into or exchangeable or
exercisable for such securities, during the seven days prior to and during the
180-day period beginning on the effective date of any underwritten Demand
Registration or any underwritten Piggyback Registration (except as part of such
underwritten registration or pursuant to registrations on Form S-8 or any
successor form), unless the underwriters managing the registered public offering
otherwise agree, and (ii) shall cause each holder of its Common Stock, or any
securities convertible into or exchangeable or exercisable for Common Stock,
purchased from the Company at any time after the date of this Agreement (other
than in a registered public offering) to agree not to effect any public sale or
distribution (including sales pursuant to Rule 144) of any such securities
during such period (except as part of such underwritten registration, if
otherwise permitted), unless the underwriters managing the registered public
offering otherwise agree. Notwithstanding the foregoing, clause (ii) of this
Section 3(b) shall not apply to any holder of the Company's Common Stock and/or
any securities convertible into or exchangeable or exercisable for Common Stock,
if such Person holds less than 1% of the Company's Common Stock on a fully
diluted basis.

     4.   Registration Procedures.  Whenever the holders of Registrable
          -----------------------
Securities have requested that any Registrable Securities be registered pursuant
to this Agreement, the Company shall use its reasonable best efforts to effect
the registration and the sale of such Registrable Securities in accordance with
the intended method of disposition thereof, and pursuant thereto the Company
shall be as expeditious as possible:

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

shall furnish to one counsel selected by the holders of a majority of the
Registrable Securities covered by such registration statement copies of all such
documents proposed to be filed, which documents shall be subject to the review
and comment of such counsel);

          (b)  notify each holder of Registrable Securities of the effectiveness
of each registration statement filed hereunder and prepare and file with the
Securities and Exchange Commission such amendments and supplements to such
registration statement and the prospectus used in connection therewith as may be
necessary to keep such registration statement effective for a period of not less
than 180 days and comply with the provisions of the Securities Act with respect
to the disposition of all securities covered by such registration statement
during such period in accordance with the intended methods of disposition by the
sellers thereof set forth in such registration statement;

          (c)  furnish to each seller of Registrable Securities such number of
copies of such registration statement, each amendment and supplement thereto,
the prospectus included in such registration statement (including each
preliminary prospectus) and such other documents as such seller may reasonably
request in order to facilitate the disposition of the Registrable Securities
owned by such seller;

          (d)  use its reasonable best efforts to register or qualify such
Registrable Securities under such other securities or blue sky laws of such
jurisdictions as any seller reasonably requests and do any and all other acts
and things which may be reasonably necessary or advisable to enable such seller
to consummate the disposition in such jurisdictions of the Registrable
Securities owned by such seller (provided that the Company shall not be required
to (i) qualify generally to do business in any jurisdiction where it would not
otherwise be required to qualify but for this subparagraph, (ii) subject itself
to taxation in any such jurisdiction or (iii) consent to general service of
process in any such jurisdiction);

          (e)  notify each seller of such Registrable Securities, at any time
when a prospectus relating thereto is required to be delivered under the
Securities Act, of the happening of any event as a result of which the
prospectus included in such registration statement contains an untrue statement
of a material fact or omits any fact necessary to make the statements therein
not misleading, and, at the request of the holders of a majority of the
Registrable Securities covered by such registration statement, the Company shall
prepare a supplement or amendment to such prospectus so that, as thereafter
delivered to the purchasers of such Registrable Securities, such prospectus
shall not contain an untrue statement of a material fact or omit to state any
fact necessary to make the statements therein not misleading;

          (f)  cause all such Registrable Securities to be listed on each
securities exchange on which similar securities issued by the Company are then
listed and, if not so listed, to be listed on the NASD automated quotation
system and, if listed on the NASD automated quotation system, use its best
efforts to secure designation of all such Registrable Securities covered by such
registration statement as a NASDAQ "national market system security" within the
meaning of Rule 11 Aa2-1 of the Securities and Exchange Commission or, failing
that, to secure NASDAQ authorization for such Registrable Securities;

          (g)  provide a transfer agent and registrar for all such Registrable
Securities not later than the effective date of such registration statement;

          (h)  enter into such customary agreements (including underwriting
agreements in customary form) and take all such other actions as the holders of
a majority of the Registrable Securities being sold or the underwriters, if any,
reasonably request in order to expedite or facilitate the disposition of such
Registrable Securities (including effecting a stock split or a combination of
shares);

          (i)  otherwise use its commercially reasonable best efforts to comply
with all applicable rules and regulations of the Securities and Exchange
Commission, and make available to its security holders, as soon as reasonably
practicable, an earnings statement covering the period of at least twelve months
beginning with the first day of the Company's first full calendar quarter after
the effective date of the registration statement, which earnings statement shall
satisfy the provisions of Section 11 (a) of the Securities Act and Rule 158
thereunder;

          (j)  in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any common stock included in such registration statement for sale in any
jurisdiction, the Company shall use its reasonable best efforts promptly to
obtain the withdrawal of such order;

          (k)  use its commercially reasonable best efforts to cause such
Registrable Securities covered by such registration statement to be registered
with or approved by such other governmental agencies or authorities as may be
necessary to enable the sellers thereof to consummate the -disposition of such
Registrable Securities; and

          (l)  in connection with any underwritten public offering, obtain a
cold comfort letter from the Company's independent public accountants in
customary form and covering such matters of the type customarily covered by cold
comfort letters addressed to the underwriters of such offering.

officers and employees performing legal or accounting duties), the expense of

          (b)  In connection with each Demand Registration and each Piggyback
Registration, the Company shall reimburse the holders of Registrable Securities
included in such registration for the reasonable fees and disbursements of one
counsel chosen by the holders of a majority of the Registrable Securities
included in such registration.

          (c)  To the extent Registration Expenses are not required to be paid
by the Company, each holder of securities included in any registration hereunder
shall pay those Registration Expenses allocable to the registration of such
holder's securities so included, and any Registration Expenses not so allocable
shall be borne by all sellers of securities included in such registration in
proportion to the aggregate selling price of the securities to be so registered.

     6.   Indemnification.
          ---------------

          (a)  The Company agrees to indemnify, to the extent permitted by law,
each holder of Registrable Securities, its officers and directors and each
Person who controls such holder (within the meaning of the Securities Act)
against all losses, claims, damages, liabilities and expenses caused by any
untrue or alleged untrue statement of material fact contained in any
registration statement, prospectus or preliminary prospectus or any amendment
thereof or supplement thereto or any omission or alleged omission of a material
fact required to be stated therein or necessary to make the statements therein
not misleading, except insofar as the same are caused by or contained in any
information furnished in writing to the Company by such holder expressly for use
therein or by such holder's failure to deliver a copy of the registration
statement or prospectus or any amendments or supplements thereto after the
Company has furnished such holder with a sufficient number of copies of the
same. In connection with an underwritten offering, the Company shall indemnify
such underwriters, their officers and directors and each Person who controls
such underwriters (within the meaning of the Securities Act) to the same extent
as provided above with respect to the indemnification of the holders of
Registrable Securities.

          (b)  In connection with any registration statement in which a holder
of Registrable Securities is participating, each such holder will furnish to the
Company in writing such information and affidavits as the Company reasonably
requests for use in connection with any such registration statement or
prospectus and, to the full extent permitted by law, shall indemnify the
Company, its directors and officers and each Person who controls the Company
(within the meaning of the Securities Act) against any losses, claims, damages,
liabilities and expenses resulting from any untrue or alleged untrue statement
of material fact contained in the registration statement, prospectus or
preliminary prospectus or any amendment thereof or supplement thereto or any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, but only to the extent
that such untrue statement or omission is contained in any information or
affidavit so furnished in writing by such holder; provided that the obligation
to indemnify will be individual, not joint and several, for each holder and
shall be limited to the net amount of proceeds received by such holder from the
sale of Registrable Securities pursuant to such registration statement.

          (c)  Any Person entitled to indemnification hereunder will (i) give
prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification (provided that the failure to give prompt notice
shall not impair any Person's

                                      -7-
<PAGE>

                                                                  EXECUTION COPY

right to indemnification hereunder to the extent such failure has not prejudiced
the indemnifying party) and (ii) unless in such indemnified party's reasonable
judgment a conflict of interest between such indemnified and indemnifying
parties may exist with respect to such claim, permit such indemnifying party to
assume the defense of such claim with counsel reasonably satisfactory to the
indemnified party. If such defense is assumed, the indemnifying party will not
be subject to any liability for any settlement made by the indemnified party
without its consent (but such consent will not be unreasonably withheld). An
indemnifying party who is not entitled to, or elects not to, assume the defense
of a claim will not be obligated to pay the fees and expenses of more than one
counsel for all parties indemnified by such indemnifying party with respect to
such claim, unless in the reasonable judgment of any indemnified party a
conflict of interest may exist between such indemnified party and any other of
such indemnified parties with respect to such claim.

          (d)  The indemnification provided for under this Agreement shall
remain in full force and effect regardless of any investigation made by or on
behalf of the indemnified party or any officer, director or controlling Person
of such indemnified party and shall survive the transfer of securities. The
Company also agrees to make such provisions, as are reasonably requested by any
indemnified party, for contribution to such party in the event the Company's
indemnification is unavailable for that reason.

     7.   Participation in Underwritten Registrations.  No Person may
          -------------------------------------------
participate in any registration hereunder which is underwritten unless such
Person (i) agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Person or Persons entitled hereunder
to approve such arrangements and (ii) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
reasonably required under the terms of such underwriting arrangements; provided
that no holder of Investor Registrable Securities included in any underwritten
registration shall be required to make any representations or warranties to the
Company or the underwriters (other than representations and warranties regarding
such holder, such holder's title to such shares and such holder's intended
method of distribution) or to undertake any indemnification obligations to the
Company or the underwriters with respect thereto, except as otherwise provided
in Section 6 hereof.

to become a party to this Agreement and succeed to all of the rights and
obligations of an "Other Stockholder" under this Agreement by obtaining an
executed counterpart signature page to this Agreement, and, upon such execution,
such person shall for all purposes be an "Other Stockholder" party to this

apply to any court of law or equity of competent jurisdiction (without posting
any bond or other security) for specific performance and for other injunctive
relief in order to enforce or prevent violation of the provisions of this

     Re:  Investment in ZEFER Common and Senior Preferred Stock

Dear [name]:

     As we have discussed, you have been invited to invest in ZEFER's common and
senior preferred stock. Your participation will require that you make a capital
commitment of up to $[________] for the benefit of ZEFER Corp., as further
described below. A copy of the Company's Certificate of Incorporation, as
amended, which describes the relative rights of the common and senior preferred
stock, is attached as Exhibit A.

     By agreeing to the foregoing capital commitment, you will be entitled to
purchase [____] shares of ZEFER common stock at a price of $[___] per share and
will be required to purchase up to [___] shares of ZEFER's senior preferred
stock at a price of $1,000.00 per share from time to time as the Company
receives funding in respect of its capital commitments from GTCR Golder Rauner
LLC ("GTCR"). For example, to date GTCR has purchased approximately 19%, or
$18,000,000, of senior preferred stock in respect of their total capital
commitment for senior preferred stock of $94,200,000. By making this capital
commitment, you will be required to fund 19% of your commitment and to make
additional purchases on a pro rata basis with GTCR as additional funds are
needed by the Company. You will be provided notice of future fundings and
arrangements for the sale to you of additional shares of senior preferred stock
will be made at that time. Your commitment will expire upon the earlier to occur
of an initial public offering of the Company's common stock or upon fulfillment
of the capital commitment.

     In order to purchase the shares of common stock and to purchase the number
of shares of senior preferred stock required to be purchased by you as of the
date hereof, please sign the enclosed copy of this letter and send the signed
letter together with a check in the amount of $[_______] to Deirdre Aubuchon,
Vice President, Finance, ZEFER Corp., 711 Atlantic Avenue, 4/th/ Floor, Boston,
MA 0211 in the return envelope provided for your convenience.

Page 2

     Of this amount, $[_______] will be used for the purchase of ZEFER common
stock and $[____] will be used for the purchase of [__] shares of ZEFER senior
preferred stock. After giving effect to the foregoing issuances of common and
senior preferred stock, the balance of your commitment will accordingly be [___]
shares of ZEFER senior preferred stock.

     By signing in the space provided below, you agree to the foregoing capital
commitment and acknowledge that the issuance of the shares of common and senior
preferred stock by the Company hereunder is expressly made in reliance on such
commitment. Further, you agree that the investment representations made on
Exhibit B hereto are true and correct in all respects. In addition, attached as
Exhibit C is a copy of the Company's Stockholders Agreement (the "Stockholders
Agreement"). By signing in the space provided below you also agree to become a
party to the Stockholders Agreement, if you are not already a party.

     Please call if you have any questions regarding the foregoing and thank you
for your continued support of ZEFER.

Exhibit B


                          INVESTMENT REPRESENTATIONS


     1.  Unregistered Stock. The Undersigned is fully aware that the ZEFER
Common and Senior Preferred Stock ("Company Stock") he or she shall receive is
being issued and sold under an exemption from registration under the Securities
Act of 1933, as amended (the "Act"), that he or she is acquiring the Company
Stock without being offered or furnished any offering literature or prospectus,
that this transaction has not been approved or reviewed by the United States
Securities and Exchange Commission or by any administrative agency charged with
the administration of the securities law of any state and that financial
statements and other documents pertaining to the Buyer have been made available
to the Undersigned and the Undersigned's representatives, including the
Undersigned's attorney and accountant.

     2.  No Duty to Register. Except as may otherwise be provided in any
registration rights agreement between the Undersigned and the Company, the
Undersigned realizes that, in the absence of the availability of Rule 144 under
the Act, any disposition by him or her of the Company Stock may require
compliance with an exemption under the Act or a registration under the Act, and
that the Buyer is under no obligation to take any action to make any such
registration or exemption so available.

     3.  Investment. The Undersigned is acquiring the Company Stock for
investment for the Undersigned's own account and not with a view to, or for
resale in connection with, any unregistered distribution thereof, and the
Undersigned has no present intention to sell, convey, dispose of or otherwise
distribute any interest in or risk related to the Company Stock except pursuant
to an effective registration statement or in a manner consistent with the
requirements of the Act and the specific exemption from the registration
requirements of the Act relied upon by Buyer. The Undersigned understands that
the Company Stock the Undersigned shall receive has not been registered under
the Act by reason of a specific exemption from the registration provisions of
the Act which depends upon, among other things, the bona fide nature of the
investment intent as expressed herein.

     4.  Ability to Bear Risk. The Undersigned confirms that the Undersigned is
able (i) to bear the economic risk of this investment, (ii) to hold the Company
Stock for a substantial period of time, and (iii) presently to afford a complete
loss of the Undersigned's investment.

     5.  Other Agreements. The Undersigned acknowledges that the transfer of the
Company Stock that the Undersigned is receiving pursuant to this Agreement is
also subject to the restrictions contained in the Stockholders Agreement

                         Form of Clarification letter


                                                       November 30, 1999

     Re:  Clarification regarding your capital commitment of $[__________]
          pursuant to that certain Letter Agreement (the "Letter Agreement"),
          dated as of September 10, 1999 (with an effective date of September
          10, 1999), between you and ZEFER Corp. (the "Company").

Dear [name]

     In light of the Company's recent restructuring of its available financing,
including the re-characterization of a portion of GTCR's capital commitments to
the Company (i.e., from an equity capital commitment for senior preferred stock
to a debt-based capital commitment of equal size), the Company is sending this
letter of clarification to you with respect to your ongoing rights and
obligations under the Letter Agreement.

     On September 10, 1999, you accepted the Company's invitation to invest in
the Company by making a capital commitment to the Company of up to $[__________]
on the terms and conditions set forth in the Letter Agreement. This acceptance
was later memorialized in the Letter Agreement referenced above.  In particular,
the Letter Agreement provides that:

          "By agreeing to the foregoing capital commitment, you will be entitled
          to purchase [______] shares of ZEFER common stock at a price of
          $[____] per share and will be required to purchase up to [___] shares
          of ZEFER's senior preferred stock at a price of $1000.00 per share
          from time to time as the Company receives funding in respect of its
          capital commitments from GTCR Golder Rauner LLC ("GTCR"). . . . By
          making this capital commitment, you will be required to fund 19% of
          your commitment [initially] and to make additional purchases on a pro
          rata basis with GTCR as additional funds are needed by the Company."

     Although it is clear from this language that the restructuring described
above does not affect any of your rights or obligations under the Letter
Agreement (including your obligation to make additional purchases of the
Company's senior preferred stock on a pro rata basis with GTCR at such times as
the Company receives funding in respect of GTCR's capital commitments), it is
equally clear that, after giving effect to such restructuring, the example set
forth in the second paragraph of the Letter Agreement, which only makes
reference to GTCR's capital commitment for senior preferred stock (but not
GTCR's new debt-based capital commitment), no longer serves as an accurate
illustration of your "additional purchase" obligation under the Letter
Agreement.  Rather, as of the restructuring, the example set forth in the Letter
Agreement should be revised to illustrate that you will be required to make
additional purchases of the Company's senior preferred stock

pursuant to the terms of the Letter Agreement at such times as the Company
receives funding in respect of any GTCR capital commitment (including GTCR's
debt-based capital commitment).

     As such, in the interest of clarity for both you and the Company going
forward, please acknowledge your receipt and acceptance of this letter by
signing in the space provided below and returning the same by facsimile to the
undersigned at 617-451-8001 by December 3, 1999.  Please call if you have any

                          STOCK RESTRICTION AGREEMENT
                          --------------------------

          THIS STOCK RESTRICTION AGREEMENT (this "Agreement") is effective as of
                                                  ---------
May 21, 1999, between ZEFER Corp., a Delaware corporation (the "Company"), and
                                                                -------
David Lubin ("Holder").
              ------

          The Company and Holder desire to enter into an agreement pursuant to
which Holder will purchase, and the Company will sell, up to 100,000 shares of
the Company's Common Stock, par value $.01 per share (the "Common Stock").  All
                                                           ------------
shares of Common Stock are so acquired by Holder are referred to herein as
"Holder Stock."  This Agreement contains certain restrictions with respect to
- -------------
the Holder Stock.  In addition, the Company desires to employ the Holder and the
Holder desires to be employed by the Company.  Certain definitions are set forth
in Section 6 of this Agreement.

          Certain provisions of this Agreement are intended for the benefit of,
and will be enforceable by, certain stockholders of the Company, namely, GTCR
Fund VI, L.P., a Delaware limited partnership ("GTCR"), GTCR VI Executive Fund,
                                                ----
L.P., a Delaware limited partnership ("Executive Fund") and GTCR Associates VI,
                                       --------------
a Delaware general partnership ("Associates Fund") (each an "Investor" and
                                 ---------------             --------
collectively, the "Investors").
                   ---------

          In consideration of the mutual covenants and promises contained herein
and other good and valuable consideration, the receipt and sufficiency of which
is hereby acknowledged by the parties hereto, the parties agree as follows:

                      PROVISIONS RELATING TO HOLDER STOCK


          1.   Purchase and Sale of Holder Stock.
               ----------------------------------

          (a)  Upon execution of this Agreement, the Holder will purchase, and
the Company will sell, 100,000 shares of Common Stock at a price of $.50 per
share. The Company will deliver to Holder the certificates representing such
Holder Stock, and Holder will deliver to the Company a cashier's check or
certified check or wire transfer of funds in the aggregate amount of $4,387.50
and a promissory note in the form of Exhibit A attached hereto in an aggregate
                                     ---------
principal amount of $45,612.50 (the "Holder Note").
                                     -----------

          (b)  Within 30 days after the date hereof, Holder will make an
effective election with the Internal Revenue Service under Section 83(b) of the
Internal Revenue Code and the regulations promulgated thereunder in the form of
Exhibit B attached hereto.
- ---------

          (c)  Until the occurrence of a Sale of the Company or a Public
Offering, all certificates evidencing shares of Holder Stock shall be held by
the Company for the benefit of the Holder and the other holder(s) of Holder
Stock. Upon the occurrence of a Sale of the Company or a Public Offering, the
Company will return the certificates for the Holder Stock to the record holders
thereof.

          (d)  In connection with the purchase and sale of the Holder Stock,
Holder represents and warrants to the Company that:

                                      -1-
<PAGE>

               (i)   The Holder Stock to be acquired by Holder pursuant to this
     Agreement will be acquired for Holder's own account and not with a view to,
     or intention of, distribution thereof in violation of the Securities Act,
     or any applicable state securities laws, and the Holder Stock will not be
     disposed of in contravention of the Securities Act or any applicable state
     securities laws.

               (ii)  Holder is an employee of the Company, is sophisticated in
     financial matters and is able to evaluate the risks and benefits of the
     investment in the Holder Stock.

               (iii) Holder is able to bear the economic risk of his investment
     in the Holder Stock for an indefinite period of time because the Holder
     Stock has not been registered under the Securities Act and, therefore,
     cannot be sold unless subsequently registered under the Securities Act or
     an exemption from such registration is available.

               (iv)  Holder has had an opportunity to ask questions and receive
     answers concerning the terms and conditions of the offering of Holder Stock
     and has had full access to such other information concerning the Company as
     he/she has requested.

               (v)   This Agreement constitutes the legal, valid and binding
     obligation of Holder, enforceable in accordance with its terms, and the
     execution, delivery and performance of this Agreement by Holder does not
     and will not conflict with, violate or cause a breach of any agreement,
     contract or instrument to which Holder is a party or any judgment, order or
     decree to which Holder is subject.

               (vi)  Holder has not and will not take any action that will
     conflict with, violate or cause a breach of any noncompete, nonsolicitation
     or confidentiality agreement to which Holder is a party to or by which
     Holder is bound.

               (vii) Holder is a resident of the Commonwealth of Massachusetts.

          (e)  As an inducement to the Company to issue the Holder Stock to
Holder, and as a condition thereto, Holder acknowledges and agrees that neither
the issuance of the Holder Stock to Holder nor any provision contained herein
shall entitle Holder to remain in the employment of the Company or any of its
Subsidiaries or affect the right of the Company to terminate Holder's employment
at any time for any reason.

          (f)  Concurrently with the execution of this Agreement, (i) Holder
shall execute in blank ten stock transfer powers in the form of Exhibit C
attached hereto (the "Stock Powers") with respect to the Holder Stock and shall
deliver such Stock Powers to the Company. The Stock Powers shall authorize the
Company to assign, transfer and deliver the shares of Holder Stock to the
appropriate acquiror thereof pursuant to Section 3 below or Section 5 of the
Stockholders Agreement and under no other circumstances, and (ii) the Holder's
spouse shall execute the consent in the form of Exhibit D attached hereto.
                                                ---------

          2.   Vesting of Holder Stock.
               --------------------------

          (a)  All of the shares of Holder Stock acquired hereunder shall be
subject to vesting in the manner specified in this Section 2. Except as
otherwise provided in Sections 2(b)

                                      -2-
<PAGE>

and 2(c) below, the Holder Stock will become vested in accordance with the
following schedule (the "Vesting Schedule"), if as of each such date Holder is
                         ----------------
still employed by the Company or any of its Subsidiaries:


                     Date                       Cumulative Percentage of
                     ----                       Holder Stock to be Vested
                                                -------------------------


               March 31, 2000                             20%
               March 31, 2001                             40%
               March 31, 2002                             60%
               March 31, 2003                             80%
               March 31, 2004                            100%


          (b)  After an initial Public Offering, the above Vesting Schedule
shall remain effective until the end of the quarter in which the Public Offering
occurred (the "Modification Date"), at which time the Vesting Schedule shall be
               -----------------
modified such that, so long as Holder is still employed by the Company or any of
its Subsidiaries, the Holder Stock will vest as follows:

               (i)   If the Modification Date is June 30, then an additional 5%
     of Holder Stock will vest on such Modification Date and an additional 5% of
     Holder Stock will vest on each subsequent September 30, December 31, March
     31 and June 30 so that the Holder Stock will be 100% vested on March 31,
     2004.

               (ii)  If the Modification Date is September 30, then an
     additional 10% of Holder Stock will vest on such Modification Date and an
     additional 5% of Holder Stock will vest on each subsequent December 31,
     March 31, June 30 and September 30 so that the Holder Stock will be 100%
     vested on March 31, 2004.

               (iii) If the Modification Date is December 31, then an additional
     15% of Holder Stock will vest on such Modification Date and an additional
     5% of Holder Stock will vest on each subsequent March 31, June 30,
     September 30 and December 31 so that the Holder Stock will be 100% vested
     on March 31, 2004.

               (iv)  If the Modification Date is March 31, then an additional 5%
     of Holder Stock will vest on each subsequent June 30, September 30,
     December 31 and March 31 so that the Holder Stock will be 100% vested on
     March 31, 2004.

          (c)  Upon the occurrence of a Transaction, all shares of Holder Stock
which have not yet vested shall automatically vest one business day prior to the
time of such event. The term "Transaction" shall mean (i) a Sale of the Company
                              -----------
or (ii) the liquidation, dissolution or winding up of the Company. Shares of
Holder Stock which have become vested are referred to herein as "Vested Shares"
                                                                 -------------
and all other shares of Holder Stock are referred to herein as "Unvested
                                                                --------
Shares."
- ------

          3.   Repurchase Option.
               --------------------

          (a)  In the event (i) Holder ceases to be employed by the Company and
its Subsidiaries for any reason (the "Separation") or (ii) Holder fails to make
                                      ----------
any principal or interest payment under the Holder Note after such payment
becomes due and after giving effect to any applicable grace period (a
"Triggering Event"), the Holder Stock (whether held by Holder or one
 ----------------

                                      -3-
<PAGE>

or more of Holder's transferees, other than the Company and Investors) will be
subject to repurchase pursuant to the terms and conditions set forth in this
Section 3 (the Repurchase Option").
               ------------------

          (b)  In the event of a Separation, (i) the purchase price for each
Unvested Share of Holder Stock will be Holder's Original Cost for such share and
(ii) the purchase price for each Vested Share of Holder Stock will be the Fair
Market Value for such share as at the date of the Separation; provided, however,
                                                              --------  -------
that if Holder's employment is terminated with Cause, the purchase price for
each Vested Share of Holder Stock will be Holder's Original Cost for such share.
Notwithstanding anything in this Section 3 to the contrary, upon a Triggering
Event (even if there is also a Separation), the purchase price for each share of
Holder Stock (whether a Vested Share or Unvested Share) will be Holder's
Original Cost for such shares.

          (c)  The Company may elect to purchase all or any portion of the
Unvested Shares or the Vested Shares by delivering written notice (the
"Repurchase Notice") to the holder or holders of the Holder Stock within 120
 -----------------
days after the Separation or Triggering Event. The Repurchase Notice will set
forth the number of Unvested Shares and Vested Shares to be acquired from each
holder, the aggregate consideration to be paid for such shares and the time and
place for the closing of the transaction. The number of shares to be repurchased
by the Company shall first be satisfied to the extent possible from the shares
of Holder Stock held by Holder at the time of delivery of the Repurchase Notice.
If the number of shares of Holder Stock then held by Holder is less than the
total number of shares of Holder Stock which the Company has elected to
purchase, the Company shall purchase the remaining shares elected to be
purchased from the other holder(s) of Holder Stock under this Agreement, pro
rata according to the number of shares of Holder Stock held by such other
holder(s) at the time of delivery of such Repurchase Notice (determined as
nearly as practicable to the nearest share). The number of Unvested Shares and
Vested Shares to be repurchased hereunder will be allocated among Holder and the
other holders of Holder Stock (if any) pro rata according to the number of
shares of Holder Stock to be purchased from such person.

          (d)  If for any reason the Company does not elect to purchase all of
the Holder Stock pursuant to the Repurchase Option, all other employees or
executives who are parties to an agreement with the Company which is
substantially similar in form and substance to this Agreement (each a "Senior
                                                                       ------
Manager", and collectively, the "Senior Management") on the date of the
- -------                          -----------------
Separation or Triggering Event and the Investors shall be entitled to exercise
the Repurchase Option for all or any portion of the shares of Holder Stock the
Company has not elected to purchase (the "Available Shares"). As soon as
                                          ----------------
practicable after the Company has determined that there will be Available
Shares, but in any event within 90 days after the Separation or Triggering
Event, the Company shall give written notice (the "Option Notice") to the Senior
                                                   -------------
Management and Investors setting forth the number of Available Shares and the
purchase price for the Available Shares. Senior Management and the Investors may
elect to purchase any or all of the Available Shares by giving written notice to
the Company within one month after the Option Notice has been given by the
Company. If Senior Management and the Investors elect to purchase an aggregate
number of shares greater than the number of Available Shares, the Available
Shares shall be allocated among Senior Management and the Investors based upon
the number of shares of Common Stock owned by each Senior Manager and each
Investor on a fully diluted basis. As soon as practicable, and in any event
within ten days, after the expiration of the one-month period set forth above,
the Company shall notify each holder of Holder Stock as to the

                                      -4-
<PAGE>

number of shares being purchased from such holder by the Senior Management and
the Investors (the "Supplemental Repurchase Notice"). At the time the Company
                    ------------------------------
delivers the Supplemental Repurchase Notice to the holder(s) of Holder Stock,
the Company shall also deliver written notice to each Senior Manager and each
Investor setting forth the number of shares such Senior Manager and such
Investor is entitled to purchase, the aggregate purchase price and the time and
place of the closing of the transaction. The number of Unvested Shares and
Vested Shares to be repurchased hereunder shall be allocated among the Company,
Senior Management and the Investors pro rata according to the number of shares
of Holder Stock to be purchased by each of them.

          (e)  The closing of the purchase of the Holder Stock pursuant to the
Repurchase Option shall take place on the date designated by the Company in the
Repurchase Notice or Supplemental Repurchase Notice, which date shall not be
more than one month nor less than five days after the delivery of the later of
either such notice to be delivered.  The Company will pay for the Holder Stock
to be repurchased by it pursuant to the Repurchase Option with (i) a check or
wire transfer of funds for (A) any shares of Holder Stock to be repurchased at
Holder's Original Cost and (B) in the case of Holder Stock to be repurchased at
Fair Market Value, that portion of such Holder Stock which is equal to the
Holder's Original Cost, and (ii) in the case of Holder Stock to be repurchased
at Fair Market Value, a subordinate note or notes for that  portion of such
Holder Stock which exceeds the Holder's Original Cost; it being understood and
agreed that such note or notes shall be payable in up to two annual installments
beginning on the first anniversary of the closing of such repurchase and bearing
interest (payable quarterly) at a rate per annum equal to the prime rate as
published in The Wall Street Journal from time to time.  Notwithstanding
             -----------------------
anything in this Section 3 to the contrary, any amounts to be paid by the
Company with a check or wire transfer of funds pursuant to this Section 3(e)
shall first be reduced (on a dollar for dollar basis) by all amounts outstanding
under any bona fide debts owed by Holder to the Company.  Each Senior Manager
and each Investor will pay for the Holder Stock to be purchased by each of them
pursuant to the Repurchase Option with a check or wire transfer of funds.  The
Company, the Senior Management and the Investors will be entitled to receive
customary representations and warranties from the sellers regarding each
seller's title to such Holder Stock.

          (f)  Notwithstanding anything to the contrary contained in this
Agreement, all repurchases of Holder Stock by the Company shall be subject to
applicable restrictions contained in the Delaware General Corporation Law and in
the Company's and its Subsidiaries' debt and equity financing agreements. If any
such restrictions prohibit the repurchase of Holder Stock hereunder which the
Company is otherwise entitled or required to make, the Company may make such
repurchases as soon as it is permitted to do so under such restrictions.

          (g)  Notwithstanding anything to the contrary contained in this
Agreement, if the Fair Market Value of a share of Holder Stock is finally
determined to be an amount at least 10% greater than the per share repurchase
price for such share of Holder Stock in the Repurchase Notice or in the
Supplemental Repurchase Notice, each of the Company, the Senior Management and
the Investors shall have the right to revoke its exercise of the Repurchase
Option for all or any portion of the Holder Stock elected to be repurchased by
it by delivering notice of such revocation in writing to the holders of Holder
Stock during the thirty-day period beginning on the date that the Company and/or
the Senior Management and/or the Investors are given written notice that the
Fair Market Value of a share of Holder Stock was finally determined to be an

                                      -5-
<PAGE>

amount at least 10% greater than the per share repurchase price for Holder Stock
set forth in the Repurchase Notice or in the Supplemental Repurchase Notice.

          (h)  The provisions of this Section 3 shall terminate with respect to
Vested Shares upon consummation of a Public Offering or the occurrence of a
Transaction.

          4.   Restrictions on Transfer of Holder Stock.
               -----------------------------------------

          (a)  Legend.  The certificates representing the Holder Stock will
               ------
bear a legend in substantially the following form:

                 "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ORIGINALLY
                 ISSUED AS OF MAY 21, 1999, HAVE NOT BEEN REGISTERED UNDER THE
                 SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT BE

                 STATEMENT UNDER THE ACT OR AN EXEMPTION FROM REGISTRATION

                 REPURCHASE OPTIONS AND CERTAIN OTHER AGREEMENTS SET FORTH IN A

               ------------------
transfer or dispose of any Holder Stock (except pursuant to an effective
registration statement under the Securities Act) without first delivering to the
Company a written notice describing in reasonable detail the proposed transfer,
together with an opinion of counsel (reasonably acceptable in form and substance
to the Company) that neither registration nor qualification under the Securities
Act and applicable state securities laws is required in connection with such
transfer. In addition, if the holder of the Holder Stock delivers to the Company
an opinion of counsel that no subsequent transfer of such Holder Stock shall
require registration under the Securities Act, the Company shall promptly upon
such contemplated transfer deliver new certificates for such Holder Stock which
do not bear the Securities Act portion of the legend set forth in Section 5(a).
If the Company is not required to deliver new certificates for such Holder Stock
not bearing such legend, the holder thereof shall not transfer the same until
the prospective transferee has confirmed to the Company in writing its agreement
to be bound by the conditions contained in this Section 5.

Holder Stock is not listed on any securities exchange or quoted in the NASDAQ
System or the over-the-counter market, the Fair Market Value will be the fair

Repurchase Notice (or if no Repurchase Notice is delivered, then within ten days
after delivery of the Supplemental Repurchase Notice).  Upon receipt of the
Holder's written notice of objection, the Board and the Holder will negotiate in

determination when subtracted from the appraiser's determination of Fair Market
Value has the greater absolute value; provided that, in the event that there is
no difference between each party's absolute value, then the expenses of such
appraiser shall be shared equally by the parties.  The determination of such
appraiser as to Fair Market Value shall be final and binding upon all parties.

                    ------------
Agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,

               ----------------------------------------------------------------
Where any accounting determination or calculation is required to be made under
this Agreement or the exhibits hereto, such determination or calculation (unless
otherwise provided) shall be made in accordance with GAAP, consistently applied,
except that if because of a change in GAAP the Company would have to alter a
previously utilized accounting method or policy in order to remain in compliance
with GAAP, such determination or calculation shall continue to be made in
accordance with the Company's previous accounting methods and policies.  All
numbers set forth herein which refer to share prices or amounts will be
appropriately adjusted to reflect stock splits, stock dividends, combinations of
shares and other recapitalizations affecting the subject class of stock.

consideration in accordance with this Agreement), and such shares shall be
deemed purchased in accordance with the applicable provisions hereof and the
Company (and/or the Investors and/or any other Person acquiring securities)
shall be deemed the owner and holder of such shares, whether or not the
certificates therefor have been delivered as required by this Agreement.

          (o)  No Pledge or Security Interest.  The purpose of the Company's
               ------------------------------
retention of the Holder's stock certificates and executed stock powers is solely

not constitute a pledge by the Holder of, or the granting of a security interest
in, the underlying stock.

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

          (a)  Definition.  For purposes of this Note, an Event of Default shall
               ----------

     under the Federal Bankruptcy Code; or Maker petitions or applies to any
     tribunal for the appointment of a custodian, trustee, receiver or
     liquidator of any substantial part of Maker's assets, or commences any
     proceeding relating to Maker under any bankruptcy, reorganization,
     arrangement, insolvency, readjustment of debt, dissolution or liquidation
     law of any jurisdiction; or any such petition or application is filed, or
     any such proceeding is commenced, against Maker and either (A) Maker by any
     act indicates its approval thereof, consent thereto or acquiescence therein
     or (B) such petition, application or proceeding is not dismissed within 60
     days.

          (b)  Consequences of Events of Default.

          If an Event of Default of the type described in subparagraph 3(a)(ii)
has occurred the aggregate principal amount of the Note (together with all
accrued interest thereon and all other amounts payable in connection therewith)
shall become immediately due and payable without any action on the part of the
Company, and Maker shall immediately pay to the Company all amounts due and
payable with respect to the Note.

          If an Event of Default of the type described in subparagraph 3(a)(i)
has occurred and continued for 5 days, the Company may declare all or any
portion of the outstanding principal amount of the Note (together with all
accrued interest thereon and all other amounts due in connection therewith) due
and payable and demand immediate payment of all or any portion of the
outstanding principal amount of the Note.

          Maker, or his successors and assigns, hereby waives diligence,
presentment, protest and demand and notice of protest and demand, dishonor and
nonpayment of this Note, and expressly agrees that this Note, or any payment
hereunder, may be extended from time to time and that the Company may accept
security for this Note or release security for this Note, all without in any way
affecting the liability of Maker hereunder.
<PAGE>

          In the event that Maker fails to pay any amounts due hereunder when
due, Maker shall pay to the Company, in addition to such amounts due, all costs
of collection, including reasonable attorneys fees.

     4.   Amendment and Waiver.  Except as otherwise expressly provided herein,
          ---------------------
the provisions of the Note may be amended and Maker may take any action herein
prohibited, or omit to perform any act herein required to be performed by it,
only if Maker has obtained the written consent of the Company.

     5.   Cancellation.  After all principal and accrued interest at any time
          -------------
owed on this Note has been paid in full, this Note shall be surrendered to Maker
for cancellation and shall not be reissued.

     6.   Place of Payment.  Payments of principal and interest are to be
          -----------------
delivered to the Company at the following address:

               ZEFER Corp.
               711 Atlantic Avenue
               Boston, MA 02110
               Attention:  Chief Financial Officer

or to such other address or to the attention of such other person as specified
by prior written notice to Maker.

     7.   Usury Laws.  It is the intention of the Company and Maker to conform
          -----------
strictly to all applicable usury laws now or hereafter in force, and any
interest payable under this Note shall be subject to reduction to the amount not
in excess of the maximum legal amount allowed under the applicable usury laws as
now or hereafter construed by the courts having jurisdiction over such matters.
If the maturity of this Note is accelerated by reason of an election by the
Company resulting from an Event of Default, voluntary prepayment by Maker or
otherwise, then earned interest may never include more than the maximum amount
permitted by law, computed from the date hereof until payment, and any interest
in excess of the maximum amount permitted by law shall be canceled automatically
and, if theretofore paid, shall at the option of the Company either be rebated
to Maker or credited on the principal amount of this Note, or if this Note has
been paid, then the excess shall be rebated to Maker.  The aggregate of all
interest (whether designated as interest, service charges, points or otherwise)
contracted for, chargeable, or receivable under this Note shall under no
circumstances exceed the maximum legal rate upon the unpaid principal balance of
this Note remaining unpaid from time to time.  If such interest does exceed the
maximum legal rate, it shall be deemed a mistake and such excess shall be
canceled automatically and, if theretofore paid, rebated to Maker or credited on
the principal amount of this Note, or if this Note has been repaid, then such
excess shall be rebated to Maker.
