   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;
  .  reflects the exchange upon the closing of this offering of     shares of
     class A preferred stock, including related accrued and unpaid dividends,
     held by certain of our stockholders for     shares of common stock at an
     exchange rate based on an assumed initial public offering price of $
     per share; and
  .  assumes the conversion upon the closing of this offering of a $2.0

     of the assumed initial public offering price.

                                [LOGO OF ZEFER]

   ZEFER Corp. was founded for the purpose of providing strategy-led Internet
consulting and implementation services to both dot-com and traditional
businesses to enable them to take advantage of the Internet. We help our
clients identify business objectives and create and prioritize a portfolio of
Internet initiatives that offer a variety of ways to maximize competitiveness
in the Internet economy. 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 underlies all aspects of the client engagement and
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 integrated, multidisciplinary teams of
consultants with backgrounds in business strategy, experience design,
technology and program management. This collaborative 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
not only trained in the latest practices and technologies but are leading
developers and thought leaders in these areas.

   Our delivery model is based upon a proprietary methodology called ENABLE.
This methodology consists of four phases that we call 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;
  .  leverage 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

                             Summary Financial Data

   The following summary pro forma statement of operations data should be read
in conjunction with "Selected Pro Forma Financial Data," "Management's
Discussion and Analysis of Pro Forma Results of Operations" and the financial
statements and related notes included elsewhere in this prospectus. The
following table presents our pro forma statement of operations data for us, an
entity originally known as ZEFER Corp. and referred to in this prospectus as
Original ZEFER, the divisions of Renaissance Worldwide, Inc., Spyplane, LLC and
Waite & Company, Inc. The pro forma financial data give effect to the
acquisition of each of these businesses as if each had been acquired on January
1, 1998. The pro forma financial data do not purport to represent what our
actual results of operations would have been had each of these businesses been
acquired on January 1, 1998, nor do they project our results of operations for
any future period.

   "EBITDA" is defined as earnings before interest, income taxes, depreciation
and amortization. EBITDA is not intended to represent cash flows from
operations and should not be considered as an alternative to net income as an
indicator of our operating performance or to cash flows as a measure of
liquidity. Although we believe that EBITDA is a standard measure commonly
reported and widely used by analysts, investors and other interested parties in
our industry, EBITDA presented below may not be comparable to similarly titled
measures reported by other companies.

                                  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 have
acquired a number of businesses over the last nine months, each of which had a
limited operating history. Accordingly, our historical results of operations do
not reflect the current nature of our service offering.

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 $8.4 million for the period from our inception
to September 30, 1999 and a pro forma net loss of $23.1 million for the nine
months ended September 30, 1999. We expect to continue to incur significant
operating losses in the near term. 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
qualified personnel

   We believe that our success 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 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. 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

   Our industry is characterized by a rapidly evolving technological landscape,
evolving business methodologies and constantly changing client requirements. As
a result, our future success depends in part on our ability to anticipate and
adapt to these changes.

                                       4
<PAGE>

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. 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 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.

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;

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

  .  the introduction of new services by us or our competitors;

  .  changes in our pricing policies or those of our competitors; and

  .  our ability to attract, train and retain skilled personnel in all areas
     of our business.

   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.

                                       5
<PAGE>

Our efforts to develop brand awareness may not be successful, which could
negatively impact our ability to continue to grow our business

   An important element of our growth strategy is to develop and maintain
widespread awareness of the ZEFER name among our target clients. To build name
recognition and acceptance, we plan to increase our public relations and
marketing expenses, which may cause our operating margins to decline. If our
efforts fail, we may not be able to successfully grow 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

   We generally enter into fixed-price contracts with our clients. 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.

Our failure to meet client expectations or deliver error-free services could
negatively impact our reputation, as well as our results of operations and
financial condition

   Many of our services are critical to our clients' businesses. Any errors in
the implementation of our Internet solutions or failure to meet a client's
expectations could result in:

  .  our inability to receive payment from such a client;

  .  requirements to provide additional services to a client at no charge;

  .  negative publicity about us and our services, which could adversely
     affect our ability to attract or retain clients; and

  .  claims for substantial damages against us, regardless of our
     responsibility for such failure, which may not be covered by our
     insurance policies and which may not be limited by the contractual terms
     of our engagement.

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.

                                       6
<PAGE>

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

   Substantially all of our revenues are derived from fixed-price, fixed-time
contracts for discrete client engagements that vary in size and scope. If our
clients cancel or reduce the scope of their engagements on short notice, as
they are entitled to do, we may be unable to reassign our professionals to new
engagements without delay. The cancellation or reduction 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 on March 18, 1999 through September 30,
1999, five clients accounted for approximately 33% 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,

                                       7
<PAGE>

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.

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

   We may need to raise additional funds through public or private equity or
debt financing in order to:

  .  support additional capital expenditures;

  .  take advantage of acquisition or expansion opportunities;

  .  develop new services; or

  .  address additional working capital needs.

   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

Management may invest or spend the proceeds of this offering in ways which may
not benefit the business

   Our management will retain broad discretion to allocate the proceeds of this
offering. Management's failure to apply these funds effectively could have an
adverse impact on our ability to implement our strategy. See "Use of Proceeds."

Our existing ownership structure and certain 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

   When this offering is completed, our executive officers, directors and those
stockholders who beneficially own more than five percent of our stock will, in
the aggregate, beneficially own shares representing approximately  % 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.

   In addition, 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. Please refer to "Description of Capital Stock" for a more detailed
discussion of these and other provisions.

   The factors discussed above could delay or prevent a change of control of
our company that stockholders may believe would result in better management. In
addition, these factors could depress our stock price because purchasers will
not be able to acquire a controlling interest in us or because investors may
perceive that potential acquirers will be less likely to even make an offer to
acquire such a controlling interest.

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

                                       8
<PAGE>

stockholders and by persons who exercise currently outstanding options to
acquire our common stock. Accordingly, you will experience immediate and
substantial dilution of approximately $     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
 % of the aggregate price paid by all purchasers of our stock but will own only
approximately  % 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.

Our stock price could be adversely affected by shares becoming available for
sale

   Sales of a substantial number of shares of our common stock in the public
market by existing stockholders after this offering could depress the market
price of our common stock and could impair our ability to raise capital through
the sale of additional equity securities. See "Shares Eligible for Future
Sale."

               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     shares of common
stock will be approximately $54.0 million, assuming an initial public offering
price of $     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
$62.4 million.

   We are conducting this offering primarily to enhance our ability to use our
common stock as a means of attracting and retaining key employees, to increase
our visibility and strengthen our reputation in the marketplace and to
facilitate our future access to public capital markets.

   We expect to use a portion of the net proceeds from this offering to repay
outstanding subordinated indebtedness owed to an affiliate of GTCR which
totaled $12.8 million at December 31, 1999. The GTCR indebtedness, which we
incurred in November 1999 in order to fund existing operations, bears interest
at a rate of 12.0% per annum and matures on the earliest to occur of November
24, 2004, certain changes in control or the closing of this offering. We also
intend to use a portion of the net proceeds from this offering to repay $19.4
million of outstanding bank indebtedness under a revolving line of credit. This
line of credit is payable on demand and bears interest at the prime lending
rate. We intend to use the balance of the net proceeds from this offering 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 and we may not make
any acquisitions.

   To the extent we receive additional proceeds from this offering upon the
exercise of the underwriters' over-allotment option or in the event the
offering price is in excess of the assumed initial public offering price or the
number of shares offered hereby is increased, we may use additional proceeds to
redeem shares of our common stock issued to holders of class A preferred stock
upon exchange of their shares of class A preferred. 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. See "Certain Transactions" for a
discussion of this exchange and redemption.

   Except as described above, we have not identified specific uses for the net
proceeds of this offering and we will have discretion over their use and
investment. 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.

   Certain 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.

                                 CAPITALIZATION

   The following table sets forth our actual and as adjusted capitalization as
of September 30, 1999. The actual information reflects the amendment of our
certificate of incorporation on December 1, 1999 to provide for:

  .  an increase in the number of shares of authorized common stock from
     35,000,000 to 100,000,000;

  .  a four-for-three forward stock split; and

  .  an adjustment in the par value of our common stock from $.01 per share
     to $.001 per share.

   The as adjusted information reflects:

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

  .  the application of a portion of the net proceeds to repay the $12.8
     million subordinated promissory note issued to an affiliate of GTCR in
     November 1999 and to repay $19.4 million of outstanding bank
     indebtedness under a revolving line of credit;

  .  the exchange upon the closing of this offering of     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 $     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     shares of
     common stock.

   The share numbers exclude 4,413,443 shares of common stock issuable upon
exercise of stock options outstanding as of November 30, 1999 at a weighted
average exercise price of $1.16 per share and 86,557 shares of common stock
available for issuance under our 1999 Incentive Plan and 1999 Stock Option Plan
as of November 30, 1999. This table should be read in conjunction with
"Management's Discussion and Analysis of Historical Financial Condition and
Results of Operations--Liquidity and Capital Resources" and the financial
statements and related notes included elsewhere in this prospectus. See also
"Use of Proceeds."

                                    DILUTION

   The pro forma net tangible book value of our common stock as of September
30, 1999 was approximately $    , or $     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 September 30, 1999, assuming (a) the exchange of     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 $     per share and (b) the conversion of a $2.0
million promissory note issued to Renaissance Worldwide, Inc. into     shares
of common stock. After giving effect to the sale by us of     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 the $12.8 million subordinated promissory note issued to an
affiliate of GTCR in November 1999 and $19.4 million of outstanding bank
indebtedness under a revolving line of credit, our pro forma net tangible book
value as of September 30, 1999 would have been approximately $    , or $
per share. This represents an immediate increase in pro forma net tangible book
value of $     per share to existing stockholders and an immediate dilution in
pro forma net tangible book value of $     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:

$1.16 per share under our stock plans. To the extent any of these stock options
are exercised, there will be additional dilution to new investors.

                       SELECTED PRO FORMA FINANCIAL DATA

   The following pro forma statement of operations data should be read in
conjunction with "Management's Discussion and Analysis of Pro Forma Results of
Operations" and the financial statements and related notes included elsewhere
in this prospectus. The following tables present pro forma statement of
operations data for us, Original ZEFER, the divisions of Renaissance Worldwide,
Inc., Spyplane, LLC and Waite & Company, Inc. The pro forma statement of
operations data give effect to the acquisition of each of these businesses as
if each had been acquired on January 1, 1998 and are derived from our unaudited
financial statements and the unaudited financial statements of these
businesses. The pro forma statement of operations data have been prepared on
the same basis as the pro forma combined condensed financial statements for the
year ended December 31, 1998 and the nine months ended September 30, 1999
included elsewhere in this prospectus. The pro forma statement of operations
data do not purport to represent what our actual results of operations would
have been had each of these businesses been acquired on January 1, 1998, nor do
they project our results of operations for any future period.

   "EBITDA" is defined as earnings before interest, income taxes, depreciation
and amortization. EBITDA is not intended to represent cash flows from
operations and should not be considered as an alternative to net income as an
indicator of our operating performance or to cash flows as a measure of
liquidity. Although we believe that EBITDA is a standard measure commonly
reported and widely used by analysts, investors and other interested parties in
our industry, EBITDA presented below may not be comparable to similarly titled
measures reported by other companies.

                      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
certain 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 business combinations,
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 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.

   Most of our revenues are derived from services performed on a fixed-price
basis. 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.

   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 also 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.

                                       14
<PAGE>

   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 develops 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. We expect
these 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.

Revenues

   Revenues for the quarter ended June 30, 1999, as compared to the quarter
ended March 31, 1999, increased by $1.6 million, or 41.8%, to $5.6 million from
$4.0 million. Revenues for the quarter ended September 30, 1999, as compared to
the previous quarter, increased by $4.6 million, or 82.0%, to $10.2 million.
The increase in revenues in each quarter was primarily a result of an increase
in the number and type of clients to whom we provided Internet consulting and
implementation services, along with the increased scope and complexity of
engagements. We increased our capacity to deliver services to meet this demand
by increasing the number of billable professionals during these periods.

Operating Expenses

   Cost of Services. Cost of services for the quarter ended June 30, 1999, as
compared to the quarter ended March 31, 1999, increased by $0.6 million to $4.5
million from $3.9 million. Cost of services for the quarter ended September 30,
1999, as compared to the previous quarter, increased by $1.6 million to $6.1
million. The increase in cost of services was due primarily to an increase in
the number of billable professionals as we expanded our capacity to meet the
increase in demand for Internet consulting and implementation services for our
clients. Cost of services as a percentage of revenues decreased in each of the
quarters presented, from 99.6% in the quarter ended March 31, 1999, to 80.3% in
the quarter ended June 30, 1999 to 59.8% in the quarter ended September 30,
1999. The decrease in cost of services as a percentage of revenues was due to
an improvement in the utilization of billable professionals.

   Hiring and Training. Hiring and training expenses for the quarter ended June
30, 1999, as compared to the quarter ended March 31, 1999, increased by $0.1
million to $0.3 million from $0.2 million. Hiring and training expenses for the
quarter ended September 30, 1999, as compared to the previous quarter,
increased by $1.0 million to $1.3 million. Hiring and training expenses
increased as a percentage of revenues in each of the quarters presented from
4.8% in the quarter ended March 31, 1999, to 5.8% in the quarter ended June 30,
1999 to 13.1% in the quarter ended September 30, 1999. These increases were
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.

                                       15
<PAGE>

   Research and Innovation. We initiated our research and innovation activities
during the quarter ended June 30, 1999 and incurred $0.1 million of research
and innovation expenses in that quarter. Research and innovation expenses for
the quarter ended September 30, 1999, as compared to the previous quarter,
increased by $0.3 million to $0.4 million. Research and innovation expenses as
a percentage of revenues increased to 4.0% in the quarter ended September 30,
1999 as compared to 2.3% in the quarter ended June 30, 1999. Most of our
research and innovation expenses related to the development of our proprietary
ENABLE methodology and knowledge management infrastructure.

   Sales and Marketing. Sales and marketing expenses for the quarter ended June
30, 1999, as compared to the quarter ended March 31, 1999, increased by $0.2
million to $1.0 million from $0.8 million. Sales and marketing expenses for the
quarter ended September 30, 1999, as compared to the previous quarter,
increased by $0.6 million to $1.6 million as we began to build our sales and
marketing organization to support growth. Sales and marketing expenses as a
percentage of revenues declined in each of the quarters presented from 19.7% in
the quarter ended March 31, 1999, to 17.3% in the quarter ended June 30, 1999
to 16.0% in the quarter ended September 30, 1999. This decrease in sales and
marketing expenses as a percentage of revenues was primarily due to the more
rapid growth in revenues as compared to the increase in sales and marketing
expenses.

   General and Administrative. General and administrative expenses for the
quarter ended June 30, 1999, as compared to the quarter ended March 31, 1999,
increased by $3.0 million to $5.1 million from $2.1 million. General and
administrative expenses for the quarter ended September 30, 1999, as compared
to the previous quarter, increased by $1.0 million to $6.1 million. General and
administrative expenses as a percentage of revenues increased from 52.1% in the
quarter ended March 31, 1999 to 90.3% in the quarter ended June 30, 1999 and
then decreased to 59.4% in the quarter ended September 30, 1999. The increase
in general and administrative expenses reflects our investment in the
infrastructure required to rapidly scale our business.

   Depreciation and Amortization. Depreciation and amortization expenses for
the quarter ended June 30, 1999, as compared to the quarter ended March 31,
1999, increased by $0.1 million to $4.0 million from $3.9 million. Depreciation
and amortization expenses for the quarter ended September 30, 1999, as compared
to the previous quarter, increased by $0.8 million to $4.8 million.
Amortization of goodwill and other intangibles related to acquisitions
represented approximately $3.8 million of total depreciation and amortization
in each quarter. The increase in depreciation and amortization in each quarter
was primarily due to the increased purchases of computer equipment, software
and furniture and fixtures to support our increase in headcount and investment
in infrastructure.

Interest and Other Expense, Net

   Interest and other expense, net for the quarter ended June 30, 1999, as
compared to the quarter ended March 31, 1999, increased by $0.4 million to $1.1
million from $0.7 million. Interest and other expense, net for the quarter
ended September 30, 1999, as compared to the previous quarter, decreased by
$0.4 million to $0.7 million. The increase for the quarter ended June 30, 1999,
as compared to the quarter ended March 31, 1999, was primarily due to increased
interest expense on our class A preferred stock. The decrease for the quarter
ended September 30, 1999, as compared to the quarter ended June 30, 1999, was
primarily due to the decrease in interest expense pertaining to the divisions
of Renaissance.

Benefit from Income Taxes

   The benefit from income taxes for the quarter ended June 30, 1999 was $1.8
million, as compared to the quarter ended March 31, 1999, for which there was
no benefit from income taxes. The benefit from income taxes for the quarter
ended September 30, 1999, as compared to the previous quarter, increased by
$2.2 million to $4.0 million. The benefit from income taxes reflects the
application of net operating loss carryforwards against deferred tax
liabilities recorded in connection with certain acquisitions.

                     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 certain factors, including those set forth
under "Risk Factors" and elsewhere in this prospectus.

ZEFER's 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.

 Period from Our Inception (March 18, 1999) to September 30, 1999 Compared to
 Six Months Ended September 30, 1998 of Our Combined Predecessors

   The following discussion compares our results of operations for the period
from our inception (March 18, 1999) through September 30, 1999 to the combined
results of operations of our predecessors for the six months ended September
30, 1998. Revenues for the period from inception to September 30, 1999
increased by $4.4 million to $12.0 million from $7.6 million for the six
months ended September 30, 1998. This increase was primarily due to an
increase in the number, type and scope of client engagements, along with the
increase in the number of billable professionals, including through
acquisition, available to deliver such engagements. The operating loss for the
period from inception to September 30, 1999 of $13.0 million reflects an
increase of $12.1 million from a loss of $0.9 million for the six months ended
September 30, 1998. The net loss for the period from inception to
September 30, 1999 of $8.4 million reflects an increase of $6.4 million from a
net loss of $2.0 million for the six months ended September 30, 1998. The
increase in both operating and net losses was primarily due to increased
hiring and training, sales and marketing, research and innovation and general
and administrative expenses and reflects our investment in the infrastructure
required to scale our business rapidly.

Original ZEFER

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

   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 of $0.5 million reflect an increase over the period from
inception to April 30, 1998. Similarly, operating and net losses for the four
months ended April 30, 1999 of $2.3 million reflect the increase in spending
for the 1999 period compared to the 1998 period. Spending for the four months
ended April 30, 1999 primarily relates to investment in training, sales and
marketing and the establishment of our delivery methodology.

Divisions of Renaissance

 Five Months Ended May 31, 1999 Compared to Five Months Ended May 31, 1998


   Revenues for the five months ended May 31, 1999 decreased by $0.6 million
to $3.9 million from $4.5 million for the five months ended May 31, 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
division. The operating loss for the five months ended May 31, 1999 of $4.7
million reflects an increase of $3.3 million from a loss of $1.4 million for
the five months ended May 31, 1998. The net loss for the five months ended May
31, 1999 of $5.0 million reflects an

                                      18
<PAGE>

increase of $2.8 million from a loss of $2.2 million for the five months ended
May 31, 1998. The increases in both operating and net losses were primarily due
to increased expenses related to the creation of the customer relationship
management division and decreased utilization of billable professionals.

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

   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. The operating loss for the year ended December 31,
1998 of $3.8 million reflects a decrease of $6.5 million from operating income
of $2.7 million for the year ended December 31, 1997. The net loss for the year
ended December 31, 1998 of $4.2 million reflects a decrease of $5.5 million
from net income of $1.3 million for the year ended December 31, 1997. The
decreases in both operating and net income were primarily due to the investment
in the establishment of the customer relationship management practice.

Business Combinations

   We have completed certain strategic acquisitions that have enabled us to
gain critical resources and delivery capabilities, expand in new geographic
regions and deliver larger projects. These acquisitions were:

  .  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. 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 five months ended May 31, 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.

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 September 30, 1999, we had raised $22.5 million of
equity capital from the sale of common and preferred stock. As of September 30,
1999, we had $0.5 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.

   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. All borrowings under this line are guaranteed by GTCR. As of
September 30, 1999, there were outstanding borrowings under this line of credit
in the amount of $15.7 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 certain
restrictive covenants, including minimum levels of working capital and tangible
net worth. As of September 30, 1999, we were not in compliance with either of
our financial covenants and were in receipt of a

                                       19
<PAGE>

waiver from the bank. We also have a capital equipment line with TLP Leasing,
Inc. 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 is
payable on May 14, 2000. The remaining unpaid principal and interest on the
notes is due on May 14, 2001.

   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 may make additional borrowings from time to time subject
to the approval of the lender. 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,
certain changes in control or the completion 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. We intend to repay the outstanding balance of the loan with
net proceeds of this offering and terminate the loan agreement. Borrowings are
secured by substantially all of our assets.

   During the period from inception (March 18, 1999) through September 30,
1999, our operating activities used $5.7 million of cash. Net cash used by
operating activities during this period resulted from a net loss of $8.4
million and increases in accounts receivable of $3.1 million and prepaid
expenses and other current assets of $0.8 million. These uses of cash were
partially offset by increases in accounts payable, accrued expenses and
deferred revenue of $2.2 million, $3.6 million and $0.2 million, respectively,
and non-cash charges of $0.6 million. The increase in accounts receivable is
primarily attributable to increased volume of revenues and accounts receivable
purchased from acquired entities.

   During the period from inception through September 30, 1999, our investing
activities used $30.7 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 $4.0 million, and
an increase in long-term other assets of $0.4 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.

   During the period from inception through September 30, 1999, our financing
activities provided $36.9 million in cash. Net cash provided by financing
activities during this period resulted from net borrowings on lines of credit
of $15.6 million, proceeds from the issuance of redeemable preferred stock of
$17.8 million, proceeds from the issuance of common stock of $3.4 million and
proceeds from the repayment of subscriptions receivable of $0.1 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.
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.

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 certain 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

                                       20
<PAGE>

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 (SOP) 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 certain
capitalization criteria 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

   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 and implementation services to
both dot-com and traditional businesses, enabling them to take competitive
advantage of the Internet. 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 Internet initiatives that offer our clients a
variety of ways to maximize their competitiveness in the Internet economy.
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 had completed
engagements for 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, 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 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." This is the concept that a linear increase in the number of network
users leads to an exponential increase in the value of that network.

                                       22
<PAGE>

   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. 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, these service providers end up implementing discrete business
applications and point solutions instead of strategy-based scalable and
adaptable business solutions.

   In addition, 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 underlies all
aspects of the client engagement and 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.

   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.

                                       23
<PAGE>

   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.

   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 not only
trained in the latest practices and technologies but are leading developers and
thought leaders in these areas. 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.

   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 while
experiencing low turnover. 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.

  .  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.

                                       24
<PAGE>

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 partners, 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;

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

  .  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

                                      25
<PAGE>

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.

   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.

                                       26
<PAGE>

   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

                          With twelve information and entertainment magazines,
                          Publicaciones Semana is the largest publishing
                          company in Colombia and one of the most influential
                          publishing groups in Latin America.

[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 constituency 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, web-based editorial process linked to a back-end
content management system. We concurrently identified an opportunity to
leverage the Semana brand into 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 that has become
Colombia's leading portal, LaCiudad.com.

   We partnered with Semana to launch LaCiudad.com and Semana.com in a 20-week
timeframe. We are now working with Semana to further enhance the sites'
functionalities 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 extending its business
model to leverage the impact of the Internet. foodline's objective was to
leverage the content from its existing electronic restaurant guide by adding
transaction capability through an online restaurant reservation system.

   We began this engagement by conducting a strategic study and analysis of
foodline's Internet vision and business model to help it 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. End users log onto
foodline.com to research dining options according to their preferences and
seating availability, and can confirm 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.

                      The Children's Place is a leading specialty retailer of
                      high quality, value-priced apparel and accessories for
                      children.
[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
custom-designed technical architecture. 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 a leading technology, dHTML, which
allows for enhanced functionality without any plug-ins, thereby keeping the
site easy to use.

   In addition to strong sales performance, 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 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 leading healthcare distribution and
                      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.
                            [LOGO OF ZUELLIG PHARMA]

   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 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 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 through a
permission-based security model. 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.

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,

                                       28
<PAGE>

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 our alliance partners.

Clients

   During the period from inception (March 18, 1999) through September 30,
1999, we derived approximately 65% of our revenues from services performed for
traditional businesses and approximately 35% from dot-com businesses. During
this period, we completed engagements for approximately 90 clients. Most of our
clients are located in the United States, although we have performed
engagements for international clients.

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 partners. ZEFER 360(degrees)
affords our employees, clients and partners 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

                                       29
<PAGE>

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 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 and McKinsey & Company;

  .  traditional IT services 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.


                                       30

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.

   Richard L. Nolan has served as a member of our board of directors since June
1999. Mr. Nolan has served as the William Barclay Harding Professor of
Management of Technology at the Harvard Business School since 1991.

Executive Officers

   Each officer serves at the discretion of our board of directors and holds
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
serves for a staggered three-year term. Messrs. Seibel and Tjan serve in the
class whose term expires in 2001, Messrs. Canfield and McAdam serve in the
class whose term expires in 2002 and Messrs. Jabbar, Lubin and Nolan serve in
the class whose term expires in 2003. At each annual meeting of stockholders, a
class of directors will be elected for a three-year term to succeed the
directors of the same class whose terms are then expiring.

Compensation of Directors

   We provide non-employee directors with a per diem of $1,000 for each meeting
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
stock, which is now exercisable for 40,000 shares of common stock as a result
of our stock split effective as of December 1, 1999. Upon his election to the
board in mid-December 1999, Mr. Jabbar received a nonstatutory stock option to
purchase 30,000 shares of common stock. Such options, which have a weighted
average exercise price of $2.57 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, Lubin 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, Lubin and Nolan. 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. Up to
2,500,000 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 incentive plan.

   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;


                                       35
<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 certain mergers, liquidations or other acquisition events,
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;

                                       36
<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.

   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 directors may
increase Mr. Seibel's base salary in its discretion based upon our achievement
of certain 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, certain 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.

                                       37
<PAGE>

   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;

  .  permit us to repurchase only unvested shares of restricted stock if the
     executive's employment is terminated by us;

  .  provide that the rights of repurchase will terminate only upon certain
     changes in control;

  .  provide for a purchase price for repurchased shares equal to the
     original purchase price of the stock paid by the executive;

  .  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 Mr.
Tjan's shares of restricted stock that have not vested. Mr. Tjan's restricted
stock vests

                                       38
<PAGE>

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."

   Under a senior management agreement entered with us on May 21, 1999, Mr.
Torbey began to receive a base salary of $160,000 per year in May 1999, which
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.

   Under a senior management agreement entered with us on September 13, 1999,
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 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
anniversary, 86% on the fourth anniversary and will be fully vested on the

- --Waite & Company, Inc."

Management" for a description of additional equity investments that each of the
above executives has made in us.

                              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 96.4% of our
class A preferred stock (all of which will be exchanged into common stock or
redeemed in connection with this offering) . After this offering, the GTCR
Funds will beneficially own   % of our common stock. Two of our directors,
Messrs. Canfield and McAdam, are principals 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 $    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. We may make additional borrowings from
time to time subject to approval of the lender. 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 beginning December 31,
1999. The loan will become due upon the completion of this offering. We intend
to repay the outstanding balance of the loan with net proceeds of this offering
and terminate the loan agreement.

   Concurrently with the execution of the loan agreement, we repurchased from
the GTCR Funds 1,650,450 shares of common stock at the issuance price of $0.125
per share and 1,499 shares of class A preferred stock at the issuance price of
$1,000 per share. 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. GTCR Capital Partners, LP exercised
both warrants in full in November 1999.

   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 certain financial targets 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.

Additional Equity Purchases by Management

   We have entered into agreements with certain executives whereby the
executives have agreed to invest in our stock on a proportionate basis at any
time that the GTCR Funds make an investment in us. Since our

                                       40

   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 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
shares of class A preferred stock would be exchanged for an aggregate of
shares of common stock, based on an assumed initial public offering price of
$   per share and a liquidation value for all class A preferred stock,
including accrued and unpaid dividends, of $    as of December 31, 1999. In the
event that the underwriters exercise their over-allotment option or in the
event the offering price is in excess of the assumed initial public offering
price or the number of shares offered hereby is increased, we will apply the
additional net proceeds received by us to redeem shares of common stock that
had been 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.

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. 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

                                       41
<PAGE>

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. 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.

Stockholders Agreement

   We have entered into to a stockholders agreement with GTCR, all of our
directors and executive officers who own our securities and certain other of
our stockholders. Each party to the stockholders agreement has agreed to vote
all shares held by such party to elect the following persons to our board of
directors: Mr. Seibel and one executive of the company designated by our chief
executive officer, two representatives of GTCR, and three independent persons
chosen jointly by GTCR and the chief executive officer. The voting provisions
terminate upon the consummation of this offering. With certain exceptions, the
stockholders agreement also provides that each stockholder has the right to
participate in certain sales of our stock made by GTCR, and that we and each
stockholder have a right of first refusal in shares of stock being transferred
by a stockholder. All of the above restrictions on transfer shall terminate
upon the consummation of this offering. Additionally, the parties to the
stockholders agreement have agreed to approve and to take certain actions with
respect to certain changes in control of our company. Also, the parties have
agreed to take certain actions in connection with this offering that may be

                          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:

  .      shares of common stock; and

  .  options to purchase an aggregate of 4,413,443 shares of our common stock
     with a weighted average per share exercise price of $1.16.

   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 Certain 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. Subject to certain
exceptions, 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

                                       44
<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 certain 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 certain 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.

   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       shares of our common stock
outstanding (assuming no exercise of outstanding options or warrants to
purchase common stock). Of these outstanding shares, the      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      shares of common stock outstanding after this offering
are deemed "restricted securities" under Rule 144. Of these securities,

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

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

   Stockholders holding of record an aggregate of approximately     shares of
common stock, including approximately     shares held of record by our
executive officers and directors (but excluding     shares beneficially held
but not held of record by such officers and directors), on the date of this
prospectus, have agreed that, for a period of 180 days after the date of this
prospectus, they will not sell, consent to sell or otherwise dispose of any
shares of our common stock, or any shares convertible into or exchangeable for
shares of our common stock, owned directly by such persons or with respect to
which they have the power of disposition, without the prior written consent of
Credit Suisse First Boston Corporation, acting on behalf of the representatives
of the underwriters.

   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 (approximately
   shares immediately after this offering) 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 certain 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 and, beginning 90 days after the
date of this prospectus (subject to the 180-day lock-up agreement described
above), 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       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.

Registration Rights

   After this offering, the holders of approximately     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 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 certain 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.

                                       48
<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 certain 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 certain 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.


                                       49

   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

                                       50
<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.

   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 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.

   We, our officers and directors and substantially all of our existing
stockholders and option holders have agreed not to offer, sell, contract to
sell, pledge or otherwise dispose of, directly or indirectly, or file with the
SEC a registration statement under the Securities Act relating to, any
additional shares of our common stock or securities convertible into or
exchangeable or exercisable for any of our common stock, or enter into a
transaction that would have the same effect, or publicly disclose the intention
to make any such offer, sale, pledge, disposition or filing, without the prior
written consent of Credit Suisse First Boston Corporation for a period of 180
days after the date of this prospectus, except in our case for issuances
pursuant to the exercise of employee stock options, employee stock purchases
pursuant to the terms of any plan in effect on the date of this prospectus or
the issuance of shares pursuant to the exercise of any warrants outstanding on
the date of this prospectus.

   The underwriters have reserved for sale, at the initial public offering
price, up to     shares of common stock for our employees, directors and
certain 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 certain liabilities
under the Securities Act of 1933, 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.

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 September 30, 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 September 30, 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 generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of ZEFER Corp. as of September
30, 1999, and the results of its operations and its cash flows for the period
from inception (March 18, 1999) through September 30, 1999, in conformity with
generally accepted accounting principles.

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 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

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 generally
accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                               September 30, 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 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 September 30, 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-based
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. 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 September 30,
1999, the Company has a provision for estimated losses of $471,249 related to
uncompleted contracts. Included in accounts receivable at September 30, 1999
are amounts which have not yet been billed totaling approximately $2,223,000.
Billings received in advance of services performed are classified as deferred
revenue.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)
                               September 30, 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 and short-term commercial paper that are subject to minimal
credit and market risks.

   (e) 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 September 30, 1999, the Company
recorded revenues from one customer who represented 12% 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 September 30, 1999, the Company had accounts receivable from one customer
who represented 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.

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

   (g) 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 life of the related lease for equipment under
capital lease and leasehold improvements.

   (h) Long-Lived Assets The Company reviews its long-lived assets, including
goodwill and other intangible assets, for impairment as events and
circumstances indicate the carrying amount of an asset may not be recoverable.
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 September 30, 1999, none of the Company's long-lived
assets was impaired.

   (i) 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.

                               September 30, 1999


   (j) 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.

   (k) 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 weighted average shares outstanding excludes 7,884,667 shares of unvested
restricted common stock (see Note 10(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. 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).

   (l) Pro Forma Net Loss per Share (Unaudited) The Company's historical
capital structure at September 30, 1999 is not indicative of its capital
structure prior to the closing of the IPO due to the automatic exchange of all
shares of 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 September 30, 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 issued in
the IPO.

   (m) 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.

   (n) 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 maker is a combination 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, respectively.

   (o) 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.

   (p) 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 recognized 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:

   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 September 30, 1999, the Company
has recorded accumulated amortization related to its intangible assets of
$4,261,134.

   (e) Pro Forma Disclosures (Unaudited) The following unaudited pro forma
consolidated amounts for the period from inception through September 30, 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 September 30, 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

                                  ZEFER CORP.

                               September 30, 1999

67.0% of the outstanding common stock of the Company. 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 September 30, 1999, no amounts
have been payable under the management fee arrangement. This management fee
agreement terminates upon the consummation of an IPO.

(6) Income Taxes

   At September 30, 1999, the Company had approximately $9,947,000 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 September 30, 1999, the Company has
incurred losses before benefit from income taxes of approximately $14,151,000,
which is the primary component of the Company's deferred tax asset at September
30, 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 the full amount of the current
period net operating losses as an offset to this deferred tax liability.

$20,000,000 unsecured demand line of credit (the Line) with a bank. Borrowings
on the Line accrue interest at the prime lending rate (8.5% at September 30,
1999) and interest is payable monthly. All borrowings under the line are
guaranteed by GTCR. The Line expires in December 1999. At September 30, 1999,
the Company had $15,670,000 outstanding under the 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 of credit
expires December 15, 1999 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.

                               September 30, 1999


   In connection with the acquisition of Original ZEFER by the Company, the
Company assumed the Revolving Line. At September 30, 1999, the Company was not
in compliance with either of its financial covenants and was in receipt of a
waiver from the bank. At September 30, 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
September 30, 1999, the Company had $237,133, $288,577 and $459,570,
respectively, outstanding under the Equipment Line, which are classified as
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 (5.4%
at September 30, 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:

   (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.

(10) Capital Stock

   (a) Redeemable Preferred Stock As of September 30, 1999, the Company has
authorized a total of 96,632 shares of Class A redeemable preferred stock
(Class A Preferred Stock), of which 18,143 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.

                               September 30, 1999

   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 is generally occurs over a four-year period from the issuance date until
vesting is complete.

   (c) GTCR Investment On March 23, 1999, the Company entered into a stock
purchase agreement with GTCR whereby GTCR would provide up to $100,000,000 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. Under the agreement, upon the approval of the
Board and at the request of GTCR, GTCR may purchase up to 30,400,000 shares of
common stock at a price of $0.13 per share and up to 96,200 shares of Class A
Preferred Stock at a price of $1,000 per share. Through September 30, 1999,
GTCR has provided equity financing in the amount of $21,025,000, consisting of
26,640,000 shares of common stock and 17,695 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.

   (d) Restricted Common Stock At various dates from the period of inception
(March 18, 1999) through September 30, 1999, the Company entered into
restricted common stock agreements with members of management and senior
management under which a total of 9,305,467 shares of common stock were issued
at prices ranging from $0.13 to $0.29 per share. The restricted common stock
vests on various dates over a period of five years; vesting accelerates
partially upon an IPO and fully upon the sale or liquidation of the Company, as
defined. If an employee terminates their employment prior to vesting, the
Company has the option to repurchase the stock at its original purchase price.

   As consideration for the restricted common stock, the employees paid cash
and executed promissory notes payable to the Company in the amount of $957,073
(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 $100,000,000.

   (e) Sales to Management During the period from inception (March 18, 1999)
through September 30, 1999, the Company sold 683,488 shares of common stock to
management at prices ranging from $0.13 to $0.29 per share and 448 shares of
Class A Preferred Stock at a price of $1,000 per share for total proceeds of
$559,713. As consideration for the unrestricted common and preferred stock, the
employees paid $103,257 in cash and issued promissory notes payable to the
Company in the amount of $456,456, 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,
the Company issued 1,266,667 shares at a price below the then current fair
market value, as determined by the Board of Directors and/or an appraisal by an
independent third party, resulting in deferred compensation of $148,500 that
will be charged to operations over the vesting term of the related restricted
common stock.

(11) Stock Options

   (a) Equity Incentive Plans  In June 1999, the Company adopted the 1999
Acquisition Stock Option Plan (the Acquisition 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 of Directors of the Company (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 Acquisition 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 2,000,000 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.

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

   Based on these assumptions, the minimum fair value of options granted in the
periods indicated above was $2,272, $0 and $1,999,807, 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.

(12) 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, 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.

(13) 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 pre-tax 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.

(14) Valuation and Qualifying Accounts

   A rollforward of the Company's allowance for doubtful accounts is as

(15) Subordinated Debt Financing

   On November 24, 1999, the Company entered into a loan agreement with GTCR
Capital Partners, LP, 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.

   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, we repurchased from GTCR 1,237,804
shares of common stock at the issuance price of $0.16 per share and 1,499
shares of class A preferred stock at the issuance price of $1,000 per share.
Simultaneously we then issued to GTCR Capital Partners, LP, the lender, a
warrant to purchase 1,237,804 shares of common stock and a warrant to purchase
1,499 shares of class A preferred stock. GTCR Capital Partners, LP exercised
both warrants in full in November 1999.

   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.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Members of

   We have audited the accompanying balance sheet of Spyplane, LLC (a
California limited liability corporation) as of December 31, 1998, and the
related statements of income, members' equity and cash flows for the period
from inception (May 7, 1998) to December 31, 1998. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audit.

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

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Spyplane, LLC as of
December 31, 1998, and the results of its operations and its cash flows for the
period from inception (May 7, 1998) to December 31, 1998, in conformity with

                         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

(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 31, 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 31, 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 31, 1999, and the results of its operations and cash
flows for the three months ended March 31, 1998, the nine months ended December
31, 1998, and the five months ended May 31, 1999, in conformity with generally
accepted accounting principles.

                            DIVISIONS OF RENAISSANCE

                     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 31, 1999, cash equivalents consisted of money market
accounts and commercial paper that are readily convertible to cash.

                                      F-34

                            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 31, 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 31, 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 31, 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:

(5) Long-term Debt

   (a) Line of Credit The Company had a line-of-credit agreement with a bank
for $2,000,000 dated December 31, 1998, which was collateralized by a
promissory note and security agreement covering substantially all assets of the
Company. The note bore interest at prime (7.75% at May 31, 1999) plus 1%. The
note matured on June 30, 1999. As of December 31, 1998 and May 31, 1999, loans
of $1,734,489 and $1,747,558 were outstanding on this line of credit,
respectively. This loan was repaid in full by Renaissance in June 1999.

   (b) Installment Note Payable The Company also had an installment note
payable agreement with a bank pursuant to which they could borrow up to
$300,000. Monthly installments of principal and interest are based on the
amount drawn with a maximum monthly payment of $6,301. Final payment is due
June 30, 2000. The note is collateralized by substantially all assets of NMC
and bears interest at prime (8.75% at May 31, 1999) plus 1%. As of December 31,
1998 and May 31, 1999, a principal balance of $283,222 and $262,755 was
outstanding on this note. This note was repaid in full by Renaissance in June
1999.

(6) Commitments

   The Company leases its office facility and equipment under noncancelable
operating leases that expire at various dates through December 31, 2002. Future
minimum lease payments are approximately $74,000 as of May 31, 1999, and extend
through 2002.

   Rent expense included in the accompanying statements of operations was
approximately $89,000, $411,000 and $243,000 for the three months ended March
31, 1998, the nine months ended December 31, 1998 and the five months ended May
31, 1999, respectively.

(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.

                         NOTES TO FINANCIAL STATEMENTS
                               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>
<CAPTION>
                                                                           Years
                                                                           -----
     <S>                                                                   <C>
     Computer equipment...................................................    5
     Office furniture and equipment....................................... 5-10
     Vehicle..............................................................    5
     Computer software....................................................    3
     Leasehold improvements...............................................    5
</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.

                               December 31, 1997


   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.

       Net capitalized computer software development costs............. $52,531
                                                                        =======
</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:

$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.

                         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-53
<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
31, 1998 are as follows:

(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

   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

   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 nine months ended
September 30, 1999. The historical condensed financial statements for the nine
month period ended September 30, 1999 have been derived from the historical
financial statements of ZEFER Corp. (the Company) for the period from inception
(March 18, 1999) through September 30, 1999, Original ZEFER for the four months
ended April 30, 1999 and the Divisions of Renaissance for the five months ended
May 31, 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 nine months ended September
30, 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
nine months ended September 30, 1999.

                                  (Unaudited)

OVERVIEW:

   ZEFER Corp., formerly ZEFER Acquisition Corporation (the Company), was
incorporated in Delaware on March 18, 1999. The Company provides integrated
Internet e-business solutions to its customers. 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 $100 million
to fund the Company's acquisitions.

   On April 30, 1999, the Company acquired all the stock of ZEFER Corporation
(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 payable to the Spyplane founders. The note payable
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).

   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

                                      F-58

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 nine
months ended September 30, 1999 combines the historical statements of
operations of (i) the Company for the period from inception (March 18, 1999)
through September 30, 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 Renaissance for the period from January 1, 1999 through
its date of acquisition (May 28, 1999) and (v) Waite for the period from
January 1, 1999 through its date of acquisition (September 13, 1999). The
results of operations of Original 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 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 and interest expense, as described in 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.

required information is given in the Registrant's consolidated financial
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.

   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.

          Funding, as defined below) in equity financing to the Company as the
          equity portion of the debt and equity financing necessary to fund such

          and similar events).  Each Purchaser shall purchase the percentage of
          such shares set forth next to such Purchaser's name on the signature
          pages attached hereto.  At the time of any such purchase, each

collectively, the "Purchasers").  Except as otherwise indicated, capitalized

          WHEREAS, the parties to this Amendment and Agreement are all of the

          The Company has been organized for the purpose of owning and operating
          a business in the electronic commerce consulting and implementation
          industry by means of first acquiring an existing business or
          businesses satisfactory to the Purchasers and thereafter from time to

          otherwise complementary to such initial acquisition. The Purchasers
          intend to provide up to $65,303,704 (including the Pre-Acquisition
          Funding (as defined below)) as the equity portion of the debt and
          equity financing necessary to fund such acquisitions and for other

                                                      -----------------------
          shall finance the Company's costs of conducting a search for the
          initial acquisition. The Purchasers' obligation to purchase any
          additional stock of the Company will be conditioned on the Company's
          not being in default under any of its material agreements, adequate
          debt financing being available to fund any proposed acquisition or
          other Approved Use on terms satisfactory to the Purchasers, and the
          Company's operations and the acquisition or other Approved Use being
          satisfactory to the Purchasers. In order to implement the foregoing,
          the Purchasers may purchase from time to time after the Closing, upon
          the written request of the Board in connection with an Approved Use,
          (i) up to an additional 5,660,000 shares of Common Stock at a price of
          $.50 per share and (ii) up to 61,973.704 shares of Class A Preferred

          as a result of stock dividends, stock splits, recapitalization and/or
          similar events). Each Purchaser shall purchase the percentage of such
          shares set forth next to such Purchaser's name on the signature pages
          attached hereto. At the time of any such purchase, each Purchaser
          shall be entitled to receive, and the Company shall be obligated to
          deliver, satisfactory representations and warranties and all other
          information and documentation as such Purchaser may reasonably
          request.

the stated period, scope or area and that the court shall be allowed to revise
the restrictions contained herein to cover the maximum duration, scope and area

breach or threatened breach of this Section 6.9, ZC or its successors or assigns
may, in addition to other rights and remedies existing in their favor, apply to
any court of competent jurisdiction for specific performance and/or injunctive

thereof with respect to Tax matters))(the "Indemnity Period") and shall remain
                                           ----------------
operative and in full force and effect through the end of the Indemnity Period
regardless of any investigation made by or on behalf of any other party hereto,
any person controlling any such party or any of their officers or directors,
whether prior to or after the execution of this Agreement.  No claim for
indemnification under this Section 8.1 for breach of a representation or
warranty may be commenced after the Indemnity Period, provided, however, that
                                                      --------  ------
claims made within the applicable time period shall survive to the extent of
such claim until such claim is finally determined and, if applicable, paid.

     (b)  Indemnification of ZC.  The Stockholders agree to jointly and
          ---------------------
severally indemnify, defend, protect, and hold harmless each of ZC, the Company
and each of their respective subsidiaries and affiliates (each in its capacity
as an indemnified party, an "Indemnitee") at all
                             ----------

                                     -24-

times from and after the date of this Agreement from and against all claims,
damages, actions, suits, proceedings, demands, assessments, adjustments, costs
and expenses (including specifically, but without limitation, reasonable
attorneys' fees and expenses of investigation) (collectively "Damages") incurred
                                                              -------
by such Indemnitee as a result of or incident to (i) any breach of any
representation or warranty of the Company or the Stockholders set forth herein
or in any certificate or other document delivered in connection herewith as of
the date made (as such representation or warranty would read if all
qualifications as to knowledge, materiality and Material Adverse Effect were
deleted from it) with respect to which a claim for indemnification is brought by
an Indemnitee within the applicable survival period, if any, described in
Section 8.1(a) and (ii) any breach or nonfulfillment by the Company or the
Stockholders, or any noncompliance by the Company or the Stockholders with, any
covenant, agreement, or obligation contained herein or in any certificate or
other document delivered in connection herewith.

     (c)  Third Person Claims.  Promptly after an Indemnitee has received notice
          -------------------
of or has knowledge of any claim by a person not a party to this Agreement
("Third Person") or the commencement of any action or proceeding by a Third
 -------------
Person, the Indemnitee shall give the Stockholder Representatives written notice
of such claim or the commencement of such action or proceeding; provided,
                                                                --------
however, that the failure to give such notice will not effect the Indemnitees'
- -------
right to indemnification hereunder with respect to such claim, action or
proceeding, except to the extent that the Stockholder Representatives have, or
the Stockholders have, been actually and materially prejudiced as a result of
such failure.  If the Stockholder Representatives notify the Indemnitee within
thirty (30) days from the receipt of the foregoing notice that they wish to
defend against the claim by the Third Person, then the Stockholder
Representatives shall have the right to assume and control the defense of the
claim by appropriate proceedings with counsel reasonably acceptable to
Indemnitee.  The Indemnitee may participate in the defense, at its sole expense,
of any such claim for which the Stockholder Representatives shall have assumed
the defense pursuant to the preceding sentence, provided, however that counsel
                                                --------  -------
for the Stockholder Representatives shall act as lead counsel in all matters
pertaining to the defense or settlement of such claims, suit or proceedings;
provided, further, however, that Indemnitee shall control the defense of any
- --------  -------  -------
claim or proceeding that in the reasonable judgment of the Indemnitee and the
Stockholder Representatives could have a material and adverse effect on
Indemnitee's business apart from the payment of money damages.  The Indemnitee
shall be entitled to indemnification for the reasonable fees and expenses of its
counsel for any period during which the Stockholder Representatives have not
assumed the defense of any claim. Whether or not the Stockholder Representatives
shall have assumed the defense of any claim, neither the Indemnitee nor the
Stockholder Representatives shall make any settlement with respect to any such
claim, suit or proceeding without the prior written consent of the other, which
consent shall not be unreasonably withheld or delayed.  It is understood and
agreed that in situations where failure to settle a claim expeditiously would
reasonably be expected to have an adverse effect on the party wishing to settle,
the failure of a party controlling the defense to act upon a request for consent
to such settlement within five business days of receipt of notice thereof shall
be deemed to constitute consent to such settlement for purposes of this Section
8.1.

     (d)  Limitations on Indemnifications.  No Indemnitee shall be entitled to
          -------------------------------
indemnification under this Section 8.1 for Damages relating to breaches of
representations and warranties set forth herein or in any certificate or
document delivered in connection herewith until the aggregate amount of Damages
incurred by such Indemnitee, together with Damages suffered with respect  to all
other claims for indemnification pursuant to this Agreement by all other
Indemnitees, exceeds $71,000, at which time such Indemnitees shall be entitled
to indemnification for the entire aggregate cumulative amount of all Damages in
excess of $71,000 up to a maximum aggregate liability equal to the Cash
Consideration;  provided, however, that with respect to the matters set forth in
                --------  -------
Section 3.15, ZC shall be entitled to indemnification for the entirety of such
Damages (which indemnification amount shall not be included in determining
whether Damages exceed $71,000 for purposes of this Section 8.1(d)).  In
addition, the Stockholders shall indemnify ZC for the entirety of any Damages
incurred by ZC as a result of (i) a failure to withhold taxes from the Exchange
Consideration paid to the Stockholders because of an inaccuracy contained in
Section 3.15(j) of the Company Disclosure Schedule or (ii) any claims by any
Stockholder arising from the recapitalization of the Company prior to the
Closing (which indemnification amount in the case of both (i) and (ii) shall not
be included in determining whether Damages exceed $71,000 for purposes of this
Section 8.1(d)). At its option, Mosaic may satisfy any of its indemnification
obligations hereunder by either (i) forfeiting to the Company a number of shares
of its ZC Common Stock sufficient to satisfy such obligations, (ii) paying such
obligations in cash or (iii) using a combination of ZC Common Stock and cash.
For purposes of the foregoing sentence, each share of ZC Common Stock to be
forfeited by Mosaic shall be valued at fair market value at the time of the
applicable claim for indemnification, which shall be (i) the average of the high
and low sale prices of the ZC Common Stock on the applicable reference date if
the ZC Common Stock is listed or traded on a national stock exchange or market
or (ii) the good faith determination of the Board of Directors of ZC of the fair
value of such share as of the applicable reference date. The maximum liability
of any individual Stockholder shall not exceed the Cash Consideration received
by such Stockholder.

     (e)  Indemnification by ZC.  Subject to the provisions of this Section 8.1,
          ---------------------
ZC agrees to indemnify, defend, protect and hold harmless each of the
Stockholders (the "Stockholder Indemnitees") from and against any and all
Damages incurred or suffered by such Stockholder Indemnitees as a result of or
incident to (i) any breach of any representation or warranty of ZC set forth
herein or in any certificate or other document delivered in connection herewith
as of the date made (as such representation or warranty would read if all
qualifications as to knowledge, materiality and Material Adverse Effect were
deleted from it) with respect to which a claim for indemnification is brought by
such Stockholder Indemnitees within the applicable survival period, if any,
described in Section 8.1(a), (ii) any breach or nonfulfillment by ZC, or any
noncompliance by ZC with, any covenant, agreement, or obligation of ZC contained
herein or in any certificate or other document delivered in connection herewith
as of the date made (the "Stockholder Damages").

     (f)  Certain Adjustments.  The Indemnitees and Stockholder Indemnitees
          -------------------
agree that for purposes of computing the amount of Damages incurred by any
Indemnitee or Stockholder

                                     -26-
<PAGE>

Indemnitee, there shall be deducted (i) an amount equal to the amount of any tax
benefit received, or an amount equal to the present value of any tax benefit
receivable, by such Indemnitee or Stockholder Indemnitee in connection with such
Damages or the circumstances giving rise thereto and (ii) an amount equal to the
amount of any insurance proceeds, indemnification payments, contribution
payments or reimbursements received or receivable by such Indemnitee or
Stockholder Indemnitee in connection with such Damages or the circumstances
giving rise thereto.

     SECTION 8.2  Survival.  The agreements set forth in Section 8.1 shall
survive independently and Article I and Sections 6.4 and 6.7 shall survive the
Closing indefinitely.

     SECTION 8.3  Notices.  All notices and other communications given or made

writing.

     (3)  The Company shall immediately cease and cause to be terminated any
existing discussions or negotiations with any persons (other than ZEFER)
conducted heretofore with respect to any of the foregoing.  The Company agrees
not to release any third party from the confidentiality provisions of any
confidentiality agreement to which the Company is a party.

     (4)  The Company shall ensure that the officers, directors and employees
of the Company and any investment banker or other advisor or representative
retained by the Company are aware of the restrictions described in this Section
5.2.

                                  ARTICLE VI

                             ADDITIONAL AGREEMENTS

     SECTION 6.1   Access to Information.  Upon reasonable notice, the Company
and ZEFER shall each afford to the officers, employees, accountants, counsel and
other representatives of the other, reasonable access, during the period from

contracts, commitments and records and, during such period, the Company and
ZEFER each shall furnish promptly to the other party, and shall send copies

     SECTION 6.2   Consents; Approvals.  The Company and ZEFER shall each use
their reasonable efforts to obtain all consents, waivers, approvals,

governmental and regulatory rulings and approvals), and the Company and ZEFER
shall make all filings (including, without limitation, all filings with United
States governmental or regulatory agencies) required in connection with the

prompt notice to ZEFER and ZEFER Northeast, and ZEFER and ZEFER Northeast shall
give prompt notice to the Company, of (i) the occurrence or nonoccurrence of any
event the occurrence or nonoccurrence of which would be likely to cause any
representation or warranty contained in this Agreement to become materially
untrue or inaccurate, or (ii) any failure of the Company, the Equityholders,
ZEFER or ZEFER Northeast, as the case may be, materially to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it hereunder; provided, however, that the delivery of any notice pursuant to
this Section shall not limit or otherwise affect the remedies available
hereunder to the party receiving such notice; and provided further that failure
to give such notice shall not be treated as a breach of covenant for the
purposes of Sections 7.2(a) or 7.3(a) unless the failure to give such notice
results in material prejudice to the other party.

     SECTION 6.4   Further Action.  Upon the terms and subject to the conditions
hereof each of the parties hereto shall use all reasonable efforts to take, or
cause to be taken, all actions and to do, or cause to be done, all other things
necessary, proper or advisable to consummate and make effective as promptly as

necessary registrations and filings, and otherwise to satisfy or cause to be
satisfied all conditions precedent to its obligations under this Agreement.

     SECTION 6.5   Public Announcements.  ZEFER and the Company shall consult
with each other before issuing any press release with respect to this Agreement
or the transactions contemplated hereby and shall not issue any such press
release or make any such public statement without the prior consent of the other
party, which shall not be unreasonably withheld; provided, however, that ZEFER
may, without the prior consent of the Company, issue such press release or make
such public statement as may upon the advice of counsel be required by law if it
has used reasonable efforts to consult with the Company prior thereto.

     SECTION 6.6   Conveyance Taxes.  ZEFER, ZEFER Northeast and the Company
shall cooperate in the preparation, execution and filing of all returns,
questionnaires, applications, or other documents regarding any gains, sales,
use, transfer, value added, stock transfer and stamp taxes, any transfer,
recording, registration and other fees, and any similar taxes which become

                                      -19-
<PAGE>

payable in connection with the transactions contemplated hereby that are
required or permitted to be filed at or before the Closing.

     SECTION 6.7   Reservation of Shares.  ZEFER agrees to reserve 10,000 shares
of ZEFER Common Stock for future grants of stock or options to employees of the
Company following the Closing Date, which shares shall be separate and apart
from any additional shares that may be issued under any employee benefit plan of
ZEFER in which such employees are entitled to participate.

     SECTION 6.8   Noncompetition/Nonsolicitation.  (a)  For a period of 18
months after the Closing Date (the "Noncompete Period"), each Equityholder shall
                                    -----------------
not, within the United States, directly or indirectly own, manage, control,
participate in, consult with, render services for, or in any manner engage in
any business competing with the web page design, digital branding and consulting
businesses of ZEFER, ZEFER Northeast or their subsidiaries or any such business
in which ZEFER, ZEFER Northeast or any of their subsidiaries has requested and
received information relating to the acquisition of such business by ZEFER,
ZEFER Northeast and the subsidiaries and of which such Equityholder had
knowledge prior to the termination of such Equityholder's Employment Period (as
defined in the Employment Agreement); provided that passive ownership of less
than 5% of the outstanding stock of any publicly-traded corporation shall not,
in and of itself, be deemed to violate this Section 6.8.

          (b)  During the Noncompete Period, each Equityholder shall not
directly or indirectly through another entity (i) induce or attempt to induce
any employee of ZEFER, ZEFER Northeast or their subsidiaries to leave the employ
of ZEFER, ZEFER Northeast or such subsidiary, or in any way interfere with the
relationship between ZEFER, ZEFER Northeast and any subsidiary and any employee
thereof, (ii) hire any person who was an employee of ZEFER, ZEFER Northeast or
any subsidiary within 180 days prior to the time such employee was hired by the
Equityholder, (iii) induce or attempt to induce any customer, supplier, licensee
or other business relation of ZEFER, ZEFER Northeast or any subsidiary to cease
doing business with ZEFER, ZEFER Northeast or such subsidiary or in any way
interfere with the relationship between any such customer, supplier, licensee or
business relation and ZEFER, ZEFER Northeast and any subsidiary or (iv) directly
or indirectly acquire or attempt to acquire an interest in any business relating
to the web page design, digital branding and consulting business of ZEFER, ZEFER
Northeast and any subsidiary or with which ZEFER, ZEFER Northeast or any
subsidiary has entertained discussions or has requested and received information
relating to the acquisition of such business by ZEFER, ZEFER Northeast and any
subsidiary and of which such Equityholder had knowledge prior to the termination
of such Equityholder's Employment Period (as defined in the Employment
Agreement).

          (c)  If, at the time of enforcement of this Section 6.8, a court holds
that the restrictions stated herein are unreasonable under circumstances then
existing, the parties hereto agree that the maximum duration, scope or
geographical area reasonable under such circumstances shall be substituted for
the stated period, scope or area and that the court shall be allowed to revise
the restrictions contained herein to cover the maximum duration, scope and area
permitted by law.  The parties hereto agree that money damages would be an
inadequate remedy for any breach of this Section 6.8.  Therefore, in the event a
breach or threatened breach of this Section 6.8, ZEFER,

                                      -20-
<PAGE>

ZEFER Northeast or its successors or assigns may, in addition to other rights
and remedies existing in their favor, apply to any court of competent
jurisdiction for specific performance and/or injunctive or other relief in order
to enforce, or prevent any violations of, the provisions hereof (without posting
a bond or other security).

     SECTION 6.9  Employee Bonus Pool.  On the date that is six months after the
Closing Date (the "Employee Bonus Date"), or in any event, not later than thirty
                   -------------------
(30) days thereafter, ZEFER shall cause the Company to pay to each employee
listed on Schedule 6.9 attached hereto a bonus in the amount listed on such
schedule, provided that such employee was employed by the Company (or another
division or subsidiary of ZEFER) on the Employee Bonus Date, and provided
further that in the event such employee is not so employed on the Employee Bonus
Date, the Company shall, if so directed by the Equityholders, pay such bonus to
such employee. The aggregate amount of bonuses paid pursuant to this Section 6.9
shall not exceed $1.0 million.

applicable to the transactions contemplated by this Agreement, which makes the
consummation of the transactions contemplated by this Agreement illegal; and

     (2)   Governmental Actions.  There shall not have been instituted, pending

                                INDEMNIFICATION

     SECTION 8.1  Indemnification.

     (1)  Survival of Representations and Warranties.  The representations and
          ------------------------------------------
warranties of the Company, the Equityholders, ZEFER and ZEFER Northeast made in
this Agreement and in the documents and certificates delivered in connection
herewith shall survive the Closing until the second anniversary of the Closing
Date (except for those contained in (i) Sections 2.2 (Authority), 2.5 (The
Units), 3.3 (Capitalization), 3.4 (Authority Relative to this Agreement) and
3.11 (Employee Benefit Plans, Employment Agreements), which shall survive the
Closing and shall continue in full force and effect without limit as to time
(subject to any applicable statutes of limitations and any extensions or waivers
thereof with respect to employee benefit matters) and (ii) Section 3.15 (Taxes),
which shall survive the Closing and shall continue in full force and effect
until 60 days after the expiration of the applicable statute of limitations,
including any extensions or waivers thereof)(the "Indemnity Period") and shall
                                                  ----------------
remain operative and in full force and effect through the end of the Indemnity
Period regardless of any investigation made by or on behalf of any other party
hereto, any person controlling any such party or any of their officers or
directors, whether prior to or after the execution of this Agreement.  No claim
for indemnification under this Section 8.1 for

                                      -23-
<PAGE>

breach of a representation or warranty may be commenced after the Indemnity
Period, provided, however, that claims made within the applicable time period
        --------  -------
shall survive to the extent of such claim until such claim is finally determined
and, if applicable, paid.

     (2)  Indemnification of ZEFER and ZEFER Northeast.  The Equityholders agree
          --------------------------------------------
to jointly and severally indemnify, defend, protect, and hold harmless each of
ZEFER, ZEFER Northeast the Company and each of their respective subsidiaries and
affiliates (each in its capacity as an indemnified party, an "Indemnitee") at
                                                              ----------
all times from and after the date of this Agreement from and against all claims,
damages, actions, suits, proceedings, demands, assessments, adjustments, costs
and expenses (including specifically, but without limitation, reasonable
attorneys' fees and expenses of investigation) (collectively "Damages") incurred
                                                              -------
by such Indemnitee as a result of or incident to (i) any breach of any
representation or warranty of the Company or the Equityholders set forth herein
or in any certificate or other document delivered in connection herewith as of
the date made (as such representation or warranty would read if all
qualifications as to knowledge, materiality and Material Adverse Effect were
deleted from it) with respect to which a claim for indemnification is brought by
an Indemnitee within the applicable survival period, if any, described in
Section 8.1(a) and (ii) any breach or nonfulfillment by the Company or the
Equityholders, or any noncompliance by the Company or the Equityholders with,
any covenant, agreement, or obligation contained herein or in any certificate or
other document delivered in connection herewith.

                                      -24-
<PAGE>

     (3)  Third Person Claims.  Promptly after an Indemnitee has received notice
          -------------------
of or has knowledge of any claim by a person not a party to this Agreement
("Third Person") or the commencement of any action or proceeding by a Third
- --------------
Person, the Indemnitee shall give the Equityholders written notice of such claim
or the commencement of such action or proceeding; provided, however, that the
                                                  --------  -------
failure to give such notice will not effect the Indemnitees' right to
indemnification hereunder with respect to such claim, action or proceeding,
except to the extent that the Equityholders have been actually and materially
prejudiced as a result of such failure.  If the Equityholders notify the
Indemnitee within thirty (30) days from the receipt of the foregoing notice that
they wish to defend against the claim by the Third Person, then the
Equityholders shall have the right to assume and control the defense of the
claim by appropriate proceedings with counsel reasonably acceptable to
Indemnitee.  The Indemnitee may participate in the defense, at its sole expense,
of any such claim for which the Equityholders shall have assumed the defense
pursuant to the preceding sentence, provided, however that counsel for the
                                    --------  -------
Equityholders shall act as lead counsel in all matters pertaining to the defense
or settlement of such claims, suit or proceedings; provided, further, however,
                                                   --------  -------  -------
that Indemnitee shall control the defense of any claim or proceeding that in
Indemnitee's reasonable judgment could have a material and adverse effect on
Indemnitee's business apart from the payment of money damages.  The Indemnitee
shall be entitled to indemnification for the reasonable fees and expenses of its
counsel for any period during which the Equityholders have not assumed the
defense of any claim. Whether or not the Equityholders shall have assumed the
defense of any claim, neither the Indemnitee nor the Equityholders shall make
any settlement with respect to any such claim, suit or proceeding without the
prior written consent of the other, which consent shall not be unreasonably
withheld or delayed.  It is understood and agreed that in situations where
failure to settle a claim expeditiously could have an adverse effect on the
party wishing to settle, the failure of a party controlling the defense to act
upon a request for consent to such settlement within five business days of
receipt of notice thereof shall be deemed to constitute consent to such
settlement for purposes of this Section 8.1.

     (4)  Limitations on Indemnifications.  No Indemnitee shall be entitled to
          -------------------------------
indemnification under this Section 8.1 for Damages relating to breaches of
representations and warranties set forth herein or in any certificate or
document delivered in connection herewith until the aggregate amount of Damages
incurred by such Indemnitee, together with Damages suffered with respect to all
other claims for indemnification pursuant to this Agreement by all other
Indemnitees, exceeds $25,000, at which time such Indemnitees shall be entitled
to indemnification for the entire aggregate cumulative amount of all Damages up
to a maximum aggregate liability equal to the Cash/Note Consideration; provided,
                                                                       --------
however, that with respect to the matters set forth in Section 3.15, ZEFER and
- -------
ZEFER Northeast shall be entitled to indemnification for the entirety of such
Damages (which indemnification amount shall not be included in determining
whether Damages exceed $25,000 for purposes of this Section 8.1(d)).

     (5)  Indemnification by ZEFER.  Subject to the provisions of this Section
          ------------------------
8.1, ZEFER agrees to indemnify, defend, protect and hold harmless each of the
Equityholders (the "Equityholder Indemnitees") from and against any and all
Damages incurred or suffered by such Equityholder Indemnitees as a result of or
incident to (i) any breach of any representation or warranty of ZEFER or ZEFER
Northeast set forth herein or in any certificate or other document delivered in
connection herewith as of the date made (as such representation or warranty
would read

                                      -25-
<PAGE>

if all qualifications as to knowledge, materiality and Material Adverse Effect
were deleted from it) with respect to which a claim for indemnification is
brought by such Equityholder Indemnitees within the applicable survival period,
if any, described in Section 8.1(a), (ii) any breach or nonfulfillment by ZEFER
or ZEFER Northeast, or any noncompliance by ZEFER or ZEFER Northeast with, any
covenant, agreement, or obligation of ZEFER or ZEFER Northeast contained herein
or in any certificate or other document delivered in connection herewith as of
the date made (the "Equityholder Damages"). ZEFER shall reimburse the
Equityholder Indemnitees for any Equityholder Damages to which this Section 8.1
relates only if a claim for indemnification is made by the Equityholder
Indemnitees within the Indemnity Period.

     (6)  Set-Off.  ZEFER, as maker of the ZEFER Notes, may set off and apply
          -------
the amount of any Damages referenced in this Section 8.1 against any amounts
payable under the ZEFER Notes.

     SECTION 8.2  Survival.  The agreements set forth in Section 8.1 shall
survive independently and Article I and Sections 6.4 and 6.7 shall survive the
Closing indefinitely.

further exercise thereof or of any other right.  All rights and remedies
existing under this Agreement are cumulative to, and not exclusive of, any

was hired, or is to be hired, by either of Thomas Waite or Allan Cohen, (iii)
induce or attempt to induce any customer, supplier, licensee or other business
relation of the Company to cease doing business with the Company or in any way
interfere with the relationship between any such customer, supplier, licensee or
business relation and the Company or (iv) directly or indirectly acquire or
attempt to acquire an interest in any business relating to the strategic
consulting business of the Company or with which the Company is entertaining
discussions or has requested and received information relating to the
acquisition of such business by the Company.

     (c)  For a period of 18 months after the Closing Date, each of Thomas Waite
and Allan Cohen agrees that he shall not perform strategic consulting services
for any business or entity that has been a customer or client of the Company
since January 1, 1998.

     (d)  If, at the time of enforcement of this Section 6.10, a court holds
that the restrictions stated herein are unreasonable under circumstances then
existing, the parties hereto agree that the maximum duration, scope or
geographical area reasonable under such circumstances shall be substituted for
the stated period, scope or area and that the court shall be allowed to revise
the restrictions contained herein to cover the maximum duration, scope and area
permitted by law. The parties hereto agree that money damages would be an
inadequate remedy for any breach of this Section 6.10.  Therefore, in the event
of a breach or threatened breach of this Section 6.10, the Buyer or its
successors or assigns may, in addition to other rights and remedies existing in
its or their favor, apply to any court of competent jurisdiction for specific
performance and/or injunctive or other relief in order to enforce, or prevent
any violations of, the provisions hereof (without posting a bond or other
security).

     SECTION 6.11  Confidentiality.

     (a) The Company and the Sellers agree that, unless and until the Closing
has been consummated, each of the Company and the Sellers will hold in strict
confidence, and will not use, any confidential or proprietary data or
information obtained from the Buyer with respect to its business or financial
condition except for the purpose of evaluating, negotiating and completing the
transaction contemplated hereby and unless the Company or the Sellers are
otherwise required to disclose such data or information by law. Information
generally known in the Buyer's industry or which has been disclosed to the
Company or the Sellers by third parties which have a right to do so shall not be
deemed confidential or proprietary information for purposes of this Agreement.
If the transactions contemplated by this Agreement are not consummated, the
Company and the Sellers will return to the Buyer (or certify that they have
destroyed) all copies of such data and information.

     (b) The Buyer agrees that, unless and until the Closing has been
consummated, the Buyer will hold in strict confidence, and will not use, any
confidential or proprietary data or information obtained from the Company or the
Sellers with respect to the Company's business or financial condition except for
the purpose of evaluating, negotiating and completing the

                                     -23-
<PAGE>

transaction contemplated hereby and unless the Buyer is otherwise required to
disclose such data or information by law. Information generally known in the
Company's industry or which has been disclosed to the Buyer by third parties
which have a right to do so shall not be deemed confidential or proprietary
information for purposes of this Agreement. If the transactions contemplated by
this Agreement are not consummated, the Buyer will return to the Company (or
certify that it has destroyed) all copies of such data and information.

     SECTION 6.12  Repayment of Loan.  Prior to the Closing Date, the Sellers
shall cause the Company to pay in full the outstanding amount of all line of
credit loans (collectively, the "Bank Loan") at any time made by BankBoston,
N.A. or any affiliate thereof to the Company, together with all interest accrued
through the date of repayment and not previously paid.

     SECTION 6.13  Pre-Closing Date Distribution.

     (a)  On the day immediately preceding the Closing Date, the Sellers shall
cause the Company to distribute to the Sellers (i) cash and (ii) accounts
receivable of the Company (the "Distributed Receivables") having an aggregate
value, immediately prior to the Closing Date, equal to the Distribution Amount
(defined below).

     (b)  Subject to the provisions of Section 6.13(e) of this Agreement, the
"Distribution Amount" shall be $171,472.00.

     (c)  The term "Closing Balance Sheet" shall mean the balance sheet of the
Company, as of the close of business on August 31, 1999 (but in all events
following the distribution of the Partnership Interest and the Artwork and the
payment in full of the Bank Loan); provided, however, that the Closing Balance
Sheet shall not include the Partnership Interest or the Artwork as an asset, or
the Bank Loan as a liability, and provided, further, that the Closing Balance
Sheet shall include as a liability the aggregate amount of bonuses, not to
exceed $400,000, to be paid to the Specified Employees and/or Thomas Waite and
Allan Cohen, as contemplated by the proviso in Section 5.1(f) of this Agreement.
Such Closing Balance Sheet, together with a written calculation of the
Distribution Amount in reasonable detail, shall be prepared by the Sellers and
delivered to the Buyer on the Closing Date.

     (d)  The Distributed Receivables shall include any and all loans to the
Partnership (item 1120 on the Closing Balance Sheet) and any and all amounts due
from employees (item 1140 on the Closing Balance Sheet) as of the close of
business on the day immediately preceding the Closing Date.

     (e)  Buyer agrees that it will cause the Company (or any successor thereto)
to act as the agent for the Sellers for purposes of collecting the Distributed
Receivables, and that it will cause the Company (or any successor thereto), as
agent, to use its reasonable best efforts to collect in full the Distributed
Receivables.  Buyer shall cause the Company (or any successor thereto) to remit
any amounts collected in respect of the Distributed Receivables to the Sellers
within five business days following the end of each week; provided, however,
that any such

                                     -24-
<PAGE>

amounts collected by the Company in payment of the Distributed Receivables shall
first be applied to the payment of any liabilities (net of any prepaid expenses
paid by the Company prior to the date of the Closing Balance Sheet and not
reflected on the Closing Balance Sheet) of the Company accrued prior to the date
of the Closing Balance Sheet and assumed by the Buyer, whether or not such
liabilities are reflected on the Closing Balance Sheet, and the balance of such
amounts collected by the Company shall be remitted to the Sellers as provided in
this Section 6.13(e). All such remittances shall be made to the Sellers in
proportion to their percentage ownership in the stock of the Company immediately
prior to the Closing. In the event that a portion of the accounts receivable
owing from a single account debtor constitutes Distributed Receivables and a
portion constitutes accounts receivable retained by the Company, Buyer shall
cause the Company (or any successor thereto) to apply any payments received from
such account debtor, which payments are not designated as payment in respect of
the Distributed Receivables or the receivables retained by the Company, to the
accounts receivable owing from such account debtor in the order in which such
account receivables were billed.

     (f)  In the event the Buyer determines that all or a portion of the
accounts receivable or unbilled client expenses (as determined as of the close
of business on August 31, 1999) retained by the Company (i.e., accounts
receivable other than Distributed Receivables), if any, will not be able to be
collected within three months following the Closing Date despite Buyer's
reasonable best efforts, the Buyer shall give notice of such determination to
Sellers.  Upon receipt of such notice, Sellers may at their option assist Buyer
in collecting the outstanding accounts receivable. In the event that not all
retained accounts receivable are collected within six months, Sellers shall pay
to the Buyer upon demand an amount equal to the uncollected accounts receivable
and, upon request of the Sellers, the Buyer shall assign such uncollected
accounts receivable (including those on account of unbilled client expenses) to
the Sellers in proportion to their percentage ownership in the stock of the
Company immediately prior to the Closing.  If the Buyer reasonably determines
that an account receivable retained by the Company is or will be uncollectible,
it may withhold from amounts otherwise owing to the Sellers under paragraph (e)
of this Section 6.13 an amount equal to the amount of the uncollectible account
receivable.

     SECTION 8.1  Termination.  This Agreement may be terminated at any time
prior to the Closing:

     (a)  by mutual written consent duly authorized by the Boards of Directors
of the Buyer and the Company; or

     (b)  by either Buyer or the Company if the Closing shall not have been
consummated by September 17, 1999 (provided that the right to terminate this
Agreement under this Section 8.1(b) shall not be available to any party whose
failure to fulfill any obligation under this Agreement has been the cause of or
resulted in the failure of the Closing to occur on or before such date); or

     (c)  by either Buyer or the Company if a court of competent jurisdiction or
governmental, regulatory or administrative agency or commission shall have
issued a nonappealable final order, decree or ruling or taken any other action

the purchase and sale of the Shares (provided that the right to terminate this
Agreement under this Section 8.1(c) shall not be available to any party who has
not complied with its obligations under Section 6.2 and such noncompliance
materially contributed to the issuance of any such order, decree or ruling or
the taking of such action); or

Sellers set forth in this Agreement shall be untrue when made, or (ii) upon a

set forth in this Agreement, in either case, such that the conditions set forth
in Section 7.2(a) or 7.2(b) would not be satisfied (either (i) or (ii) above
being a "Seller Terminating Breach"), provided, that, if such Seller Terminating
Breach is curable prior to September 17, 1999 by the Sellers or the Company
through the exercise of their or its reasonable best efforts and for so long as
the Sellers and the Company continue to exercise such reasonable best efforts,
Buyer may not terminate this Agreement under this Section 8.1(d); or

     (e)  by the Company, (i) if any representation or warranty of Buyer set
forth in this Agreement shall be untrue when made, or (ii) upon a breach by
Buyer of any covenant or agreement set forth in this Agreement, in either case,
such that the conditions set forth in Section 7.3(a) or 7.3(b) would not be
satisfied (either (i) or (ii) above being a "Buyer Terminating Breach"),
provided, that, if such Buyer Terminating Breach is curable prior to September
17, 1999 by Buyer through the exercise of its reasonable best efforts and for so
long as Buyer continues to exercise such reasonable best efforts, the Company
may not terminate this Agreement under this Section 8.1(e).

     SECTION 8.2  Effect of Termination.  In the event of the termination of
this Agreement pursuant to Section 8.1, all obligations of the parties hereunder
shall terminate without any liability of any party to any other party (other

                                  ARTICLE IX

                                INDEMNIFICATION

     SECTION 9.1  Survival of Representations and Warranties.

     (a)  The representations and warranties of the Sellers made in this
Agreement and in the documents and certificates delivered in connection herewith
shall survive the Closing for a period of two years from the Closing Date,
provided, however, that (i) the representations and warranties contained in
Sections 2.5 and 3.4 shall survive indefinitely and (ii) the representations and
warranties that relate to Taxes in Section 3.15, shall survive until the
expiration of the applicable statutes of limitations for such Taxes (including
any extensions thereof), provided, further, that representations and warranties
with respect to which a claim for indemnification is made within the applicable
survival period shall survive until such claim is finally determined and paid.

     (b)  The representations and warranties of the Buyer made in this Agreement
and in the documents and certificates delivered in connection herewith shall
survive the Closing for a period of two years following the Closing Date,
provided, however, that representations and warranties with respect to which a
claim for indemnification is made within such two-year period shall survive
until such claim is finally determined and paid.

     (c)  No claim for indemnification may be made with respect to a
representation and warranty after the expiration of the applicable survival
period, other than claims based on fraud.

     SECTION 9.2  Indemnification by the Sellers.  The Sellers, jointly and
severally, (each in his capacity as an indemnifying party, an "Indemnifying
Party") covenants and agrees that he will indemnify, defend, protect, and hold
harmless the Buyer and the Company and each of their respective subsidiaries and
affiliates (each in its capacity as an indemnified party, an "Indemnitee") at
all times from and after the date of this Agreement from and against all

                                     -29-
<PAGE>

claims, damages, actions, suits, proceedings, demands, assessments, adjustments,
costs and expenses (including specifically, but without limitation, reasonable
attorneys' fees and expenses of investigation) (collectively "Damages") incurred
by such Indemnitee as a result of or incident to:

     (a)  any breach of any representation or warranty of the Sellers set forth
herein or in any certificate or other document delivered in connection herewith
(as each such representation or warranty would read if all qualifications as to
materiality were deleted therefrom);

     (b)  any breach or nonfulfillment by the Sellers or the Company of, or any
noncompliance by the Sellers or the Company with, any covenant, agreement, or
obligation contained herein; and

     (c)  any Taxes of any kind relating to or arising in connection with the
transfer of the Shares to the Buyer;

     provided, however, that in the case of any breach by any Seller of any
representation or warranty contained in Section 2 or any covenant, agreement or
obligation contained in this Agreement, such breaching Seller shall be severally
(and not jointly and severally) liable, for any indemnification obligations
under this Section 9 resulting from such breach, and each non-breaching Seller
shall have no liability for any indemnification obligations under this Section 9
resulting from such breach.

     SECTION 9.3  Indemnification by the Buyer.  The Buyer (in its capacity as
an indemnifying party, an "Indemnifying Party") covenants and agrees that it
will indemnify, defend, protect and hold harmless each of the Sellers (each in
his capacity as an indemnified party, an "Indemnitee") at all times from and
after the date of this Agreement from and against all Damages incurred by such
Indemnitee as a result of or incident to (a) any breach of any representation or
warranty of the Buyer set forth herein or in any certificate or other document
delivered in connection herewith (as each such representation or warranty would
read if all qualifications as to materiality were deleted therefrom) and any
misrepresentation in connection with this Agreement or the transactions
contemplated hereby; and (b) any breach or nonfulfillment by the Buyer of, or
noncompliance by the Buyer with, any covenant, agreement or obligation contained
herein or in any certificate or other document delivered in connection herewith.

     SECTION 9.4  Third Person Claims.  Promptly after an Indemnitee has
received notice of or has knowledge of any claim by a person not a party to this
Agreement ("Third Person") or the commencement of any action or proceeding by a
Third Person as to which such Indemnitee desires to seek indemnification
hereunder, the Indemnitee shall give the Indemnifying Party written notice of
such claim or the commencement of such action or proceeding; provided, however,
that the failure to give such notice will not affect the Indemnitees' right to
indemnification hereunder with respect to such claim, action or proceeding,
except to the extent that the Indemnifying Party has been actually prejudiced as
a

                                     -30-
<PAGE>

result of such failure. If the Indemnifying Party notifies the Indemnitee within
30 days from the receipt of the foregoing notice that he wishes to defend
against the claim by the Third Person, then the Indemnifying Party shall have
the right to assume and control the defense of the claim by appropriate
proceedings with counsel reasonably acceptable to Indemnitee. The Indemnitee may
participate in the defense, at its sole expense, of any such claim for which the
Indemnifying Party shall have assumed the defense pursuant to the preceding
sentence, provided that counsel for the Indemnifying Party shall act as lead
counsel in all matters pertaining to the defense or settlement of such claims,
suit or proceedings; provided, however, that Indemnitee shall control the
portion of defense of any claim or proceeding seeking equitable relief against
Indemnitee that in Indemnitee's reasonable judgment could have a material and
adverse effect on Indemnitee's business apart from the payment of money damages.
The Indemnitee shall be entitled to indemnification for the reasonable fees and
expenses of its counsel for any period during which the Indemnifying Party has
not assumed the defense of any claim. Whether or not the Indemnifying Party
shall have assumed the defense of any claim, neither the Indemnitee nor the
Indemnifying Party shall make any settlement with respect to any such claim,
suit or proceeding without the prior consent of the other, which consent shall
not be unreasonably withheld or delayed. It is understood and agreed that in
situations where failure to settle a claim expeditiously could have an adverse
effect on the party wishing to settle, the failure of a party controlling the
defense to act upon a request for consent to such settlement within ten business
days of receipt of notice thereof shall be deemed to constitute consent to such
settlement for purposes of this Article 9.

     SECTION 9.5  Limitations on Indemnification.  No Indemnitee shall be
entitled to indemnification under this Article 9 for Damages for breaches of
representations and warranties until the aggregate amount of such Damages
incurred by Indemnitee exceeds $100,000, in which event such persons shall be
entitled to indemnification for the aggregate cumulative amount of all Damages
in excess of $100,000; provided, however, that the liability of any Seller for
any indemnification obligations under this Section 9 shall be limited to the
amount of the Purchase Price paid to such Seller.

     SECTION 9.6  Method of Payment.  All claims for indemnification shall be
payable in cash.

     SECTION 9.7  Exclusive Remedy.  This Section 9 shall provide the sole and
exclusive remedy for any and all losses sustained or incurred by the Sellers,
the Buyer and the Company or the successors and assigns of the foregoing other
than for equitable action and fraud.

outstanding during the three-month period (or other period in the case of the
initial Dividend Reference Date) ending upon each such Dividend Reference Date
shall be accumulated and shall remain accumulated dividends with respect to such
Share until paid to the holder thereof.

     1.C.  Distribution of Partial Dividend Payments.  Except as otherwise
           -----------------------------------------

Liquidation Value of all Shares held by such holder (plus all accrued and unpaid
dividends thereon), and the holders of Class A Preferred shall not be entitled
to any further payment.  If upon any such
<PAGE>

liquidation, dissolution or winding up of the Corporation the Corporation's
assets to be distributed among the holders of the Class A Preferred are
insufficient to permit payment to such holders of the aggregate amount which
they are entitled to be paid under this Section 2, then the entire assets
                                        ---------
available to be distributed to the Corporation's stockholders shall be
distributed pro rata among such holders based upon the aggregate Liquidation
Value (plus all accrued and unpaid dividends) of the Class A Preferred held by
each such holder. Prior to the liquidation, dissolution or winding up of the
Corporation, the Corporation shall declare for payment all accrued and unpaid
dividends with respect to the Class A Preferred, but only to the extent of funds
of the Corporation legally available for the payment of dividends. Not less than
30 days prior to the payment date stated therein, the Corporation shall mail
written notice of any such liquidation, dissolution or winding up to each record
holder of Class A Preferred, setting forth in reasonable detail the amount of
proceeds to be paid with respect to each Share and each share of Common Stock in
connection with such liquidation, dissolution or winding up.

     Section 3.   Priority of Class A Preferred on Dividends and Redemptions.
                  ----------------------------------------------------------
So long as any Class A Preferred remains outstanding, without the prior written
consent of the holders of a majority of the outstanding shares of Class A
Preferred, the Corporation shall not, nor shall it permit any Subsidiary to,
redeem, purchase or otherwise acquire directly or indirectly any Junior
Securities, nor shall the Corporation directly or indirectly pay or declare any
dividend or make any distribution upon any Junior Securities; provided that the
Corporation may repurchase shares of Common Stock from present or former
employees of the Company or its Subsidiaries in accordance with the provisions
of the Management Agreements.

     Section 4.   Redemptions.
                  -----------

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

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

     4.C.  Redemption Payments.  For each Share which is to be redeemed
           -------------------
hereunder, the Corporation shall be obligated on the Redemption Date to pay to
the holder thereof (upon surrender by such holder at the Corporation's principal
office of the certificate representing such Share) an amount in immediately
available funds equal to the Liquidation Value of such Share (plus all accrued
and unpaid dividends thereon). If the funds of the Corporation legally available
for redemption of Shares on any Redemption Date are insufficient to redeem the
total number of Shares to be redeemed on such date, those funds which are
legally available shall be used to redeem the maximum possible number of Shares
pro rata among the holders of the Shares to be redeemed based upon the aggregate
Liquidation Value of such Shares held by each such holder (plus all accrued and
unpaid dividends thereon). At any time thereafter when additional funds of the
Corporation are legally available for the redemption of Shares, such funds shall
immediately be used to redeem the balance of the Shares which the Corporation
has become obligated to redeem on any Redemption Date but which it has not
redeemed.

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

     4.E.  Determination of the Number of Each Holder's Shares to be Redeemed.
           ------------------------------------------------------------------
The number of Shares of Class A Preferred to be redeemed from each holder
thereof in redemptions hereunder shall be the number of Shares determined by
multiplying the total number of Shares to be redeemed times a fraction, the
numerator of which shall be the total number of Shares then held by such holder
and the denominator of which shall be the total number of Shares then
outstanding.

     4.F.  Dividends After Redemption Date.  No Share shall be entitled to
           -------------------------------
any dividends accruing after the date on which the Liquidation Value of such
Share (plus all accrued and unpaid dividends thereon) is paid to the holder of
such Share.  On such date, all rights of the holder of such Share shall cease,
and such Share shall no longer be deemed to be issued and outstanding.

     4.G.  Redeemed or Otherwise Acquired Shares.  Any Shares which are
           -------------------------------------
redeemed or otherwise acquired by the Corporation shall be canceled and retired
to authorized but unissued shares and shall not be reissued, sold or
transferred.

     4.H.  Other Redemptions or Acquisitions.  The Corporation shall not, nor
           ---------------------------------
shall it permit any Subsidiary to, redeem or otherwise acquire any Shares of
Class A Preferred, except as expressly authorized herein.

     4.I. Special Redemptions.
          -------------------

          (i) If a Change in Ownership has occurred or the Corporation obtains
     knowledge that a Change in Ownership is proposed to occur, the Corporation
     shall give prompt written notice of such Change in Ownership describing in
     reasonable detail the material terms and date of consummation thereof to
     each holder of Class A Preferred, but in any event such notice shall not be
     given later than five days after the occurrence of such Change in
     Ownership, and the Corporation shall give each holder of Class A Preferred
     prompt written notice of any material change in the terms or timing of such
     transaction. The holder or holders of a majority of the Class A Preferred
     then outstanding may require the Corporation to redeem all or any portion
     of the Class A Preferred owned by such holders at a price per Share equal
     to the Liquidation Value thereof (plus all accrued and unpaid dividends
     thereon) by giving written notice to the Corporation of such election prior
     to the later of (a) 21 days after receipt of the Corporation's notice and
     (b) five days prior to the consummation of the Change in Ownership (the
     "Expiration Date"). The Corporation shall give prompt written notice of any
      ---------------
     such election to all other holders of Class A Preferred within five days
     after the receipt thereof, and each such holder shall have until the later
     of (a) the Expiration Date or (b) ten days after receipt of such second
     notice to request redemption hereunder (by giving written notice to the
     Corporation) of all or any portion of the Class A Preferred owned by such
     holder.

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

series of sales, transfers and/or issuances of Common Stock by the Corporation
or any holders thereof which results in any Person or group of Persons (as the

holders of Common Stock and Class A Preferred as of the date of the Purchase
Agreement, owning more than 50% of the Common Stock outstanding at the time of
such sale, transfer or issuance or series of sales, transfers and/or issuances.

          (ii)  If a Fundamental Change is proposed to occur, the Corporation
     shall give written notice of such Fundamental Change describing in
     reasonable detail the material terms and date of consummation thereof to
     each holder of Class A Preferred not more than 45 days nor less than 20
     days prior to the consummation of such Fundamental Change, and the
     Corporation shall give each holder of Class A Preferred prompt written
     notice of any material change in the terms or timing of such transaction.
     The holder or holders of a majority of the Shares then outstanding, may
     require the Corporation to
<PAGE>

     redeem all or any portion of the Class A Preferred owned by such holders at
     a price per Share equal to the Liquidation Value thereof (plus all accrued
     and unpaid dividends thereon) by giving written notice to the Corporation
     of such election prior to the later of (a) ten days prior to the
     consummation of the Fundamental Change or (b) ten days after receipt of
     notice from the Corporation. The Corporation shall give prompt written
     notice of such election to all other holders of Class A Preferred (but in
     any event within five days prior to the consummation of the Fundamental
     Change), and each such holder shall have until two days after the receipt
     of such notice to request redemption (by written notice given to the
     Corporation) of all or any portion of the Class A Preferred owned by such
     holder.

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

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

the Corporation shall, at the request of the record holder of such certificate,

satisfactory), or, in the case of any such mutilation upon surrender of such
certificate, the Corporation shall (at its expense) execute and deliver in lieu
of such certificate a new certificate of like kind representing the number of
Shares of such class represented by such lost, stolen, destroyed or mutilated
certificate and dated the date of such lost, stolen, destroyed or mutilated
certificate, and dividends shall accrue on the Class A Preferred represented by

the close of the immediately preceding fiscal year of the corporation for the
purpose of electing directors and conducting such other proper business as may

determined by the highest ranking officer of the corporation then in office;
provided, that if such officer does not act, the board of directors shall
determine the date, time and place of such meeting.

          Section 2.  Special Meetings.  Special meetings of stockholders may
          ---------   ----------------
be called for any purpose and may be held at such time and place, within or

board of directors or the highest ranking officer then in office (the "Ranking
Officer") and shall be called by the Ranking Officer upon the written request of
holders of shares entitled to cast not less than fifty percent of the votes at

meeting and shall be delivered to the Ranking Officer.  On such written request,
the Ranking Officer shall fix a date and time for such meeting within two days

when deposited in the United States mail, postage prepaid, addressed to the

of objecting at the beginning of the meeting to the transaction of any business
because the meeting is not lawfully called or convened.

          Section 5.  Stockholders List.  The officer having charge of the
          ---------   -----------------
stock ledger of the corporation shall make, at least 10 days before every

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 annual meeting at the place where the meeting is to be
held.  The list shall also be produced and kept at the time and place of the
meeting during the whole time thereof, and may be inspected by any stockholder
who is present.

quorum is once present to commence a meeting of stockholders, it is not broken
by the subsequent withdrawal of any stockholders or their proxies.

          Section 7.  Adjourned Meetings.  When a meeting is adjourned to
          ---------   ------------------
another time and place, notice need not be given of the adjourned meeting if the
time and place thereof are announced at the meeting at which the adjournment is
taken.  At the adjourned meeting the corporation may transact any business which
might have been transacted at the original meeting.  If the adjournment is for
more than thirty days, or if after the adjournment a new record date is fixed
for the adjourned meeting, a notice of the adjourned meeting shall be given to
each stockholder of record entitled to vote at the meeting.

          Section 8.  Vote Required.  When a quorum is present, the affirmative
          ---------   -------------
vote of the majority of shares present in person or represented by proxy at the
meeting and entitled to vote on the subject matter shall be the act of the
stockholders, unless the question is one upon which by express provisions of an
applicable law or of the certificate of incorporation a different vote is

or was a director or officer of the corporation, or is or was serving at the
request of the corporation as a director, officer, member, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,

negligence, willful misconduct or breach of an agreement by such person with the
corporation.  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 such person reasonably believed to be in

or was serving at the request of the corporation as a director, officer or
member of another corporation, partnership, joint venture, trust or other
enterprise, against Losses actually and reasonably incurred by such person in
connection with the defense or settlement of such action or suit if such person
acted in good faith and in a manner reasonably believed to be within the scope
of the authority conferred on such person by the corporation or such other
entity, except that a person shall not be indemnified for any such Losses
incurred by reason of such person's gross negligence, willful misconduct or
breach of an agreement by such person with the corporation, and except that no
such 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 or the

all the circumstances of the case, such person is fairly and reasonably entitled
to indemnity for such expenses which such court shall deem proper.

          ---------    ---------
advisable by the Board of Directors, indemnify any person who is or was an

the corporation only as authorized in the specific case upon a determination
that indemnification of the director, officer, member, employee or agent is
proper in the circumstances because such person has met the applicable standard
of conduct set forth in Sections 1 and 2.  Such determination shall be made (1)
by a majority vote of directors who are not parties to such action, suit or
proceeding, even though less than a quorum, or (2) if there are no such
directors, or if such directors so direct, by independent legal counsel in a
written opinion, or (3) by the stockholders.

          Section 5.   Expenses.  Expenses (including attorneys' fees) incurred
          ---------    --------
by an officer or director in defending any civil, criminal, administrative or
investigative action, suit or proceeding shall be paid by the corporation in
advance of the final disposition of such action, suit or proceeding unless
otherwise determined by the Board of Directors in the specific case, upon
receipt of an undertaking by or on behalf of the director or officer to repay
such amount if it shall ultimately be determined that such person is not
entitled to be indemnified by the corporation as authorized in this Article V.
Such expenses (including attorneys' fees) incurred by other employees and agents
may be so paid upon such terms and conditions, if any, as the Board of Directors
deems appropriate.

advancement of expenses provided by, or granted pursuant to, this Article V
shall not be deemed exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under any statute,
by-law, agreement, vote of stockholders or disinterested directors or otherwise,

capacity while holding such office, and shall, unless otherwise provided when

officer, member, employee or agent and shall inure to the benefit of the heirs,
executors, and administrators of such person.

purchase and maintain insurance on behalf of any person who was or is a
director, officer, employee or agent of the corporation, or is or was serving at

of another corporation, partnership, joint venture, trust or other enterprise
against any liability asserted against such person and incurred by such person
in any such capacity, or arising out of such person's status as such, whether or
not the corporation would have the power to indemnify such person against such
liability under the provisions of this Article V or of the General Corporation
Law of the State of Delaware.

          Section 8.   References to "the Corporation".  For the purposes of
          ---------    -------------------------------
this Article V, references to "the corporation" shall include, in addition to
the resulting corporation, any constituent corporation (including any
constituent of a constituent) absorbed in a consolidation or merger and the
corporation which, if its separate existence had continued, would have had power
and authority to (or in fact did) indemnify its directors, officers, employees
or agents, so that any person who is or was a director, officer, employee or
agent of such constituent corporation, or is or was serving at the request of
such constituent corporation as a director, officer, member, employee or agent
of another corporation, partnership, joint venture, trust or other enterprise,
shall stand in the same position under the provisions of this Article with
respect to the resulting or surviving corporation as such person would have with
respect to such constituent corporation if its separate existence had continued.

agent other than the corporation or its employee or (2) by a registrar, other

Officer, President, Chief Financial Officer, Vice-President, Secretary, or

against the Corporation on account of the loss, theft or destruction of any such
certificate or the issuance of such new certificate.

equitable or other claim to or interest in such share or shares on the part of
any other person, whether or not it shall have express or other notice thereof.

          (c)  Until the occurrence of a Sale of the Company or a Public
Offering, all certificates evidencing shares of Executive Stock shall be held by

Offering, the Company will return the certificates for the Executive Stock to
the record holders thereof.

Executive represents and warrants to the Company that:

               (i)   The Executive Stock to be acquired by Executive pursuant to
     this Agreement will be acquired for Executive's own account and not with a
     view to, or intention of, distribution thereof in violation of the

     benefits of the investment in the Executive Stock.

               (iii) Executive is able to bear the economic risk of his
     investment in the Executive Stock for an indefinite period of time because
     the Executive Stock has not been registered under the Securities Act and,
     therefore, cannot be sold unless subsequently registered under the
     Securities Act or an exemption from such registration is available.

               (iv)  Executive has had an opportunity to ask questions and
     receive answers concerning the terms and conditions of the offering of

     obligation of Executive, enforceable in accordance with its terms, and the
     execution, delivery and performance of this Agreement by Executive does not
     and will not conflict with, violate or cause a breach of any agreement,
     contract or instrument to which Executive is a party or any judgment, order
     or decree to which Executive is subject.

               (vi)  Executive 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 Executive is a party to or by which

          (e) As an inducement to the Company to issue the Executive Stock to
Executive, and as a condition thereto, Executive acknowledges and agrees that

contained herein shall entitle Executive to remain

of the Company to terminate Executive's employment at any time for any reason,

Stock to the appropriate acquiror thereof pursuant to Section 3 below or Section

Executive's spouse shall execute the consent in the form of Exhibit D attached

to make any principal or interest payment under the Executive Note after such
payment becomes due and after giving effect to any applicable grace period (a
"Triggering Event"), the Executive Stock (whether held by Executive or one or
 ----------------
more of Executive'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 Executive Stock will be Executive's Original Cost for such
share and (ii) the purchase price for each Vested Share of Executive Stock will
be the Fair Market Value for such share as at the date of the Separation;
provided, however, that if Executive's employment is terminated with Cause, the
- --------  -------
purchase price for each Vested Share of Executive Stock will be Executive'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 Executive Stock (whether a Vested Share or
Unvested Share) will be Executive'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 Executive 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 Executive Stock held by Executive at the time of delivery of the
Repurchase Notice.  If the number of shares of Executive Stock then held by
Executive is less than the total number of shares of Executive Stock which the
Company has elected to purchase, the Company shall purchase the remaining shares
elected to be purchased from the other holder(s) of

Executive Stock under this Agreement, pro rata according to the number of shares
of Executive Stock held by such other holder(s) at the time of delivery of such
Repurchase Notice (determined as nearly as practicable to the nearest share).
The number of Unvested Shares and Vested Shares to be repurchased hereunder will
be allocated among Executive and the other holders of Executive Stock (if any)
pro rata according to the number of shares of Executive Stock to be purchased
from such person.

          (d)  If for any reason the Company does not elect to purchase all of
the Executive Stock pursuant to the Repurchase Option, all other 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 Executive 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 Executive Stock as to the 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 Executive 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 Executive Stock
to be purchased by each of them.

          (e)  The closing of the purchase of the Executive Stock pursuant to
the Repurchase Option shall take place on the date designated by the Company in
the Repurchase Notice or Supplemental Repurchase Notice, which date shall not be
more than one month nor less than five days after the delivery of the later of
either such notice to be delivered. The Company will pay for the Executive Stock
to be repurchased by it pursuant to the Repurchase Option with (i) a check or
wire transfer of funds for (A) any shares of Executive Stock to be repurchased
at Executive's Original Cost and (B) in the case of Executive Stock to be
repurchased at Fair Market Value, that portion of such Executive Stock which is
equal to the Executive's Original Cost, and (ii) in the case of Executive Stock
to be repurchased at Fair Market Value, a subordinate note or notes for that

portion of such Executive Stock which exceeds the Executive'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 Executive to the Company.
Each Senior Manager and each Investor will pay for the Executive 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 Executive Stock.

          (f)  Notwithstanding anything to the contrary contained in this
Agreement, all repurchases of Executive Stock by the Company shall be subject to
applicable restrictions contained in the Delaware General Corporation Law and in
the Company's and its Subsidiaries' debt and equity financing agreements.  If
any such restrictions prohibit the repurchase of Executive Stock hereunder which
the Company is otherwise entitled or required to make, the Company may make such
repurchases as soon as it is permitted to do so under such restrictions.

          (g)  Notwithstanding anything to the contrary contained in this
Agreement, if the Fair Market Value of a share of Executive Stock is finally
determined to be an amount at least 10% greater than the per share repurchase
price for such share of Executive Stock in the Repurchase Notice or in the
Supplemental Repurchase Notice, each of the Company and the Investors shall have
the right to revoke its exercise of the Repurchase Option for all or any portion
of the Executive Stock elected to be repurchased by it by delivering notice of
such revocation in writing to the holders of Executive Stock during the thirty-
day period beginning on the date that the Company and/or the Investors are given
written notice that the Fair Market Value of a share of Executive Stock was
finally determined to be an amount at least 10% greater than the per share
repurchase price for Executive 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 Executive Stock.
               -------------------------------------------

          (a)  Transfer of Executive Stock.  The holder of Executive Stock shall
               ---------------------------
not Transfer any interest in any shares of Executive Stock, except pursuant to
(i) the provisions of Section 3 hereof, (ii) the provisions of Section 3 of the
Stockholders Agreement (a "Participating Sale"), (iii) an Approved Sale (as
                           ------------------
defined in Section 5 of the Stockholders Agreement), or (iv) the provisions of
Section 4(b) below.

          (b)  Certain Permitted Transfers.  The restrictions in this Section 4
               ---------------------------
will not apply with respect to any Transfer of Executive Stock if made (i)
pursuant to applicable laws of descent

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

and distribution or to such Person's legal guardian in the case of any mental
incapacity or among such Person's Family Group, or (ii) at a time when (A) the
Common Stock of the Company has been trading for at least 45 consecutive days
(including the day immediately preceding such Transfer) at a price that exceeds
the initial Public Offering price by at least 20% and (B) the Common Stock bid
and asked price on the day of such Transfer was at least 20% greater than the
initial Public Offering price, but in the case of this clause (ii) only an
amount of shares per calendar year up to the lesser of (X) the number of Vested
Shares owned by Executive at the time of such Transfer and (y) 10% of the total
number of shares of Common Stock owned by Executive at the time of the Company's
initial Public Offering, or (iii) at such time as the Investors sell shares of
Common Stock in a Public Sale, but in the case of this clause (iii) only an
amount of shares (the "Transfer Amount") equal to the lesser of (C) the number
                       ---------------
of Vested Shares of Common Stock owned by Executive at the time of such Transfer
and (D) the number of shares of Common Stock owned by Executive multiplied by a
fraction (the "Transfer Fraction"), the numerator of which is the number of
               -----------------
shares of Common Stock sold by the Investors in such Public Sale and the
denominator of which is the total number of shares of Common Stock held by the
Investors prior to the Public Sale; provided that, if at the time of a Public
                                    -------- ----
Sale of shares by the Investors, Executive chooses not to Transfer the Transfer
Amount, Executive shall retain the right to Transfer an amount of Executive
Stock at a future date equal to the lesser of (x) the number of Vested Shares
owned by Executive at such future date and (y) the number of shares of Executive
Stock owned by Executive at such future date multiplied by the Transfer
Fraction; provided further, that at any particular point in time during any
          -------- -------
given calendar year the number of shares of Common Stock which the Executive has
a right to Transfer pursuant to clause (ii) above shall be reduced by the number
of shares of Common Stock which the Executive has Transferred in such calendar
year pursuant to clause (iii) above and the number of shares of Common Stock
which the Executive has a right to Transfer pursuant to clause (iii) above shall
be reduced by the number of shares of Common Stock which the Executive has
Transferred in such calendar year pursuant to clause (ii) above. Notwithstanding
anything in this Section 4 to the contrary, the restrictions contained in this
Section 4 will continue to be applicable to the Executive Stock after any
Transfer of the type referred to in clause (i) and the transferees of such
Executive Stock will agree in writing to be bound by the provisions of this
Agreement. Any transferee of Executive Stock pursuant to a transfer in
accordance with the provisions of this Section 4(b)(i) is herein referred to as
a "Permitted Transferee." Upon the transfer of Executive Stock pursuant to this
   --------------------
Section 4(b), the transferring Executive Stockholder will deliver a written
notice (a "Transfer Notice") to the Company.  In the case of a Transfer
           ---------------
pursuant to clause (i) hereof, the Transfer Notice will disclose in reasonable
detail the identity of the Permitted Transferee(s). In addition, following the
completion of an initial Public Offering, Executive, in his sole discretion, may
pledge up to $2 million worth of Vested Shares as collateral for a loan so long
as the pledgee of such stock and the Executive enter into a pledge agreement in
form and substance reasonably satisfactory to the Board, pursuant to which
pledgee, among other things, agrees that pledgee may only sell such stock in a
Public Sale.

          (c)  Termination of Restrictions.  The restrictions set forth in this
               ---------------------------
Section 4 will continue with respect to each share of Executive Stock until the
earlier of (i) the date on which such

share of Executive Stock has been transferred in a Public Sale permitted by this
Section 4, or (ii) the consummation of an Approved Sale.

          5.   Additional Restrictions on Transfer of Executive Stock.
               ------------------------------------------------------

          (a)  Legend.  The certificates representing the Executive Stock will
               ------
bear a legend in substantially the following form:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ORIGINALLY
     ISSUED AS OF MARCH 23, 1999, HAVE NOT BEEN REGISTERED UNDER THE
     SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT BE
                                              ---
     SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
     STATEMENT UNDER THE ACT OR AN EXEMPTION FROM REGISTRATION
     THEREUNDER. THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE
     ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER, CERTAIN
     REPURCHASE OPTIONS AND CERTAIN OTHER AGREEMENTS SET FORTH IN A
     SENIOR MANAGEMENT AGREEMENT BETWEEN THE COMPANY AND AN EXECUTIVE
     OF THE COMPANY DATED AS OF MARCH 23,1999. A COPY OF SUCH
     AGREEMENT MAY BE OBTAINED BY THE HOLDER HEREOF AT THE COMPANY'S
     PRINCIPAL PLACE OF BUSINESS WITHOUT CHARGE."

          (b)  Opinion of Counsel.  No holder of Executive Stock may sell,
               ------------------
transfer or dispose of any Executive Stock (except pursuant to an effective
registration statement under the Securities Act) without first delivering to the
Company an 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 Executive Stock delivers to the
Company an opinion of counsel that no subsequent transfer of such Executive
Stock shall require registration under the Securities Act, the Company shall
promptly upon such contemplated transfer deliver new certificates for such
Executive 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 Executive 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.

          (a)  Position and Duties.
               -------------------

               (i)   During the Employment Period, Executive shall serve as the

     normal duties, responsibilities and authority of the President and Chief
     Executive Officer, including, without limitation, the responsibilities
     associated with all aspects of the daily operations of the Company and the
     identification, negotiation, completion and integration of any acquisitions
     made by the Company, subject to the power of the board of directors of the
     Company (the "Board") to expand or limit such duties, responsibilities
                   -----

     corporations that do not compete with the businesses of the Company or its
     Subsidiaries so long as such service does not unduly interfere with
     Executive's duties or obligations to the Company.

          (b)  Salary, Bonus and Benefits.  During the Employment Period, the
               --------------------------
Company will pay the Executive a base salary (the "Annual Base Salary") of

$375,000 per annum, subject to any increase as determined by the Board based
upon the Company's achievements of budgetary and other objectives set by the
Board.  Notwithstanding the foregoing, the Executive's Annual Base Salary shall
be $325,000 per annum until the Company determines (i) that its EBITDA for the
previous 30 days has been sufficient to cover an increase in the Executive's
Annual Base Salary from $325,000 to $375,000 together with any increases in the
annual base salary of the Company's other 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 increases.  Executive's Annual Base
Salary for any partial year will be prorated based upon the number of days
elapsed in such year.  Upon execution of this Agreement, the Company agrees to
pay to the Executive a one-time special bonus in the amount of $80,000.  During
the Employment Period, the Executive shall also be eligible for an annual bonus
in an amount not to exceed 50% of Executive's then applicable Annual Base Salary
for such year; such bonus to be determined by the Board based upon the Company's
achievement of budgetary and other objectives set by the Board.  In addition,
during the Employment Period, the Company will provide the Executive with (i)
medical insurance benefits, (ii) a term life insurance policy with a death
benefit amount of $2,000,000, and (iii) such other benefits approved by the
Board and made available to the Company's senior management.

          (c)  Events of Separation.  The Employment Period will continue until
               --------------------
Executive's resignation, disability (as determined by the Board in its good
faith judgment) or death or until the Board decides to terminate Executive's
employment.

               -----------------------------------------------------
event that (i) the Company terminates the Executive's employment without Cause
or (ii) the Executive resigns from his position with the Company for Good
Reason, then the Executive shall be entitled to the following:

               (i)   the Company shall pay to the Executive, in a lump sum
     within 15 days after such termination or resignation, an amount equal to
     the sum of (A) any unpaid base salary owed to the Executive for services
     performed prior to such termination, plus (B) the amount of any
     compensation previously deferred by the Executive (together with any
     accrued interest or earnings thereon) and any accrued vacation pay, in each
     case to the extent not previously paid (the obligations set forth in
     clauses (A) and (B) are collectively referred to herein as the "Accrued

     day after the Company provides the notice referenced in Section 8(a), and
     (z) the second anniversary of such termination or resignation.
     Notwithstanding anything in this Section 6(c) to the contrary, in the event
     that the Executive becomes employed with another employer, then the
     payments to be made by the Company pursuant to this Section 6(c)(ii) shall
     be reduced (on a dollar for dollar basis) in an amount equal to the cash
     compensation received by Executive from such employer; and

               (iii) the Company shall continue to provide medical insurance
     benefits to the Executive and to the Executive's family at least equal to
     those medical insurance benefits that would have been provided to them in
     the absence of such termination or resignation; provided however, that such
                                                     -------- -------
     medical insurance benefits shall immediately cease upon the earliest to
     occur of (x) the close of business on the 90th day after the Company
     provides the notice referenced in Section 8(a), and (y) the second
     anniversary of such termination or resignation.  Notwithstanding anything
     in this Section 6(c) to the contrary, in the event that the Executive
     becomes employed with another employer and is eligible for medical
     insurance benefits under another employer-provided plan, then the medical
     insurance benefits to be provided by the Company pursuant to this Section
     6(c)(iii) shall be reduced to the extent that the Executive and his family
     is eligible to receive medical insurance benefits under such other
     employer-provided plan.

          (e)  Other Separations.  In the event of a Separation other than a
               -----------------
termination by the Company without cause or a resignation by the Executive for
Good Reason, the Company shall pay to the Executive (or his estate, if
applicable), in a lump sum in cash within 15 days after such Separation, an
amount equal to any Accrued Obligations.

Employment Period.  Therefore, Executive agrees that he will not disclose to any
unauthorized person or use for his own account any of such information,
observations or data without the Board's written consent, unless and to the
extent that the aforementioned matters become generally known to and available
for use by the public other than as a result of Executive's acts or omissions to
act.  Executive agrees to deliver to the Company at a Separation, or at any
other time the Company may request in writing, all memoranda, notes, plans,
records, reports and other documents (and copies thereof) relating to the
business of the Company and its affiliates (including, without limitation, all
acquisition prospects, lists and contact information) which he may then possess
or have under his control.

          8.   Noncompetition and Nonsolicitation.  Executive acknowledges that
               ----------------------------------
 in the course of his employment with the Company he will become familiar with
the Company's and its Subsidiaries' trade secrets and with other confidential
information concerning the Company and such Subsidiaries and that his services
will be of special, unique and extraordinary value to the Company. Therefore,
Executive agrees that:

          (a)  Noncompetition.  During the Employment Period and for a period of
               --------------
two years thereafter (the "Noncompete Period"), Executive shall not, within the
                           -----------------
United States, directly or indirectly own, manage, control, participate in,
consult with, render services for, or in any manner engage in any business
competing with the businesses of the Company or its Subsidiaries or any business
in which the Company or any of its Subsidiaries has requested and received
information relating to the acquisition of such business by the Company and the
Subsidiaries prior to the Separation; provided that passive ownership of less
than 5% of the outstanding stock of any publicly-traded corporation shall not,
in and of itself, be deemed to violate this Section 8(a).  Notwithstanding
anything in this Section 8 to the contrary, the Company (in its sole discretion)
can terminate the Noncompete Period effective at anytime after the first
anniversary of a Separation by delivering 90 days prior to such effective date
written notice to the Executive of the Company's intention to terminate the
Noncompete Period.


          (b)  Nonsolicitation.  During the Noncompete Period, Executive shall
               ---------------
not directly or indirectly through another entity (i) induce or attempt to
induce any employee of the Company or its Subsidiaries to leave the employ of
the Company or such Subsidiary, or in any way interfere with the relationship
between the Company and any Subsidiary and any employee thereof, (ii) hire any
person who was an employee of the Company and any Subsidiary within 180 days
prior to the time such employee was hired by the Executive, (iii) induce or
attempt to induce any customer, supplier, licensee or other business relation of
the Company and any Subsidiary to cease doing business with the Company or such
Subsidiary or in any way interfere with the relationship between any such
customer, supplier, licensee or business relation and the Company and any
Subsidiary or (iv) directly or indirectly acquire or attempt to acquire an
interest in any business relating to the

                                                                  EXECUTION COPY
                                                                  --------------

business of the Company and any Subsidiary and with which the Company and any
Subsidiary has entertained discussions or has requested and received information
relating to the acquisition of such business by the Company and any Subsidiary
in the two-year period immediately preceding a Separation.

          (c)  Enforcement.  If, at the time of enforcement of Section 7 or this
               -----------
Section 8, a court holds that the restrictions stated herein are unreasonable
under circumstances then existing, the parties hereto agree that the maximum
duration, scope or geographical area reasonable under such circumstances shall
be substituted for the stated period, scope or area and that the court shall be
allowed to revise the restrictions contained herein to cover the maximum
duration, scope and area permitted by law.  Because Executive's services are
unique and because Executive has access to confidential information, the parties
hereto agree that money damages would be an inadequate remedy for any breach of
this Agreement.  Therefore, in the event a breach or threatened breach of this
Agreement, the Company or its successors or assigns may, in addition to other
rights and remedies existing in their favor, apply to any court of competent
jurisdiction for specific performance and/or injunctive or other relief in order
to enforce, or prevent any violations of, the provisions hereof (without posting
a bond or other security).

          (d)  Additional Acknowledgments.  Executive acknowledges that the
               --------------------------
provisions of this Section 8 are in consideration of: (i) employment with the
Company, (ii) the issuance of the Executive Stock and (iii) additional good and
valuable consideration as set forth in this Agreement.  In addition, Executive
agrees and acknowledges that the restriction contained in Section 7 and this
Section 8 do not preclude Executive from earning a livelihood, nor do they
unreasonably impose limitations on Executive's ability to earn a living.  In
addition, Executive agrees and acknowledges that the potential harm to the
Company of the non-enforcement of Section 7 and this Section 8 outweighs any
potential harm to Executive of its enforcement by injunction or otherwise.
Executive acknowledges that he has carefully read this Agreement and has given
careful consideration to the restraints imposed upon Executive by this
Agreement, and is in full accord as to their necessity for the reasonable and
proper protection of confidential and proprietary information of the Company now
existing or to be developed in the future.  Executive expressly acknowledges and
agrees that each and every restraint imposed by this Agreement is reasonable
with respect to subject matter, time period and geographical area.

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.

          (c)  Severability.  Whenever possible, each provision of this

Agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law

or rule in any jurisdiction, such invalidity, illegality or unenforceability
will not affect any other provision or any other jurisdiction, but this
Agreement will be reformed, construed and enforced in such jurisdiction as if
such invalid, illegal or unenforceable provision had never been contained
herein.

          (d)  Complete Agreement.  This Agreement, those documents expressly
               ------------------
referred to herein and other documents of even date herewith embody the complete

prior understandings, agreements or representations by or among the parties,
written or oral, which may have related to the subject matter hereof in any way.


          (e)  Counterparts.  This Agreement may be executed in separate

together constitute one and the same agreement.


          (f)  Successors and Assigns.  Except as otherwise provided herein,
               ----------------------
this Agreement shall bind and inure to the benefit of and be enforceable by

assigns (including subsequent holders of Executive Stock); provided that the
rights and obligations of Executive under this Agreement shall not be assignable
except in connection with a permitted transfer of Executive Stock hereunder.


          (g)  Choice of Law.  The laws of Delaware shall govern all issues
               -------------
concerning the relative rights of the Company and its stockholders and all other
questions concerning the construction, validity and interpretation of this
Agreement, without giving effect to any choice of law or other conflict of law
provision or rule (whether of the State of Delaware or any other jurisdiction)
that would cause the application of the laws of any jurisdiction other than the
State of Delaware.


          (h)  Remedies.  Each of the parties to this Agreement (including the
               --------
Investors) will be entitled to enforce its rights under this Agreement
specifically, to recover damages and costs (including attorney's fees) caused by
any breach of any provision of this Agreement and to exercise all other rights
existing in its favor.  The parties hereto agree and acknowledge that money
damages may not be an adequate remedy for any breach of the provisions of this
Agreement and that any party may in its sole discretion apply to any court of
law or equity of competent jurisdiction (without posting any bond or deposit)
for specific performance and/or other injunctive relief in order to enforce or
prevent any violations of the provisions of this Agreement.


          (i)  Amendment and Waiver.  The provisions of this Agreement may be
               --------------------
amended and waived only with the prior written consent of the Company, the
Executive and the Majority Holders (as defined in the Purchase Agreement).


          (j)  Insurance.  The Company, at its discretion, may apply for and
               ---------
procure in its own name and for its own benefit life and/or disability insurance
on Executive in any amount or amounts considered available.  Executive agrees to
cooperate in any medical or other examination,

supply any information, and to execute and deliver any applications or other
instruments in writing as may be reasonably necessary to obtain and constitute
such insurance. Executive hereby represents that he has no reason to believe

March 23, 1999                                                       $378,100.00


          William Seibel ("Maker"), hereby promises to pay to the order of ZC
                           -----

                        -------
with interest thereon calculated from the date hereof in accordance with the
provisions of this Note.

          This Note is the Executive Note referred to in the Senior Management

"Management Agreement").  Section 1(a) of the Management Agreement contains
 --------------------
provisions for the issuance of this Note upon the terms and conditions specified
herein.  Capitalized terms used herein and not otherwise defined shall have the
meanings given to them in the Management Agreement.

     2.   Payment on Note.
          ---------------

          (a)  Term.  Subject to Section 2(b) below, the entire principal amount

     accrued interest on such principal amount (or such lesser principal amount
     then outstanding).  For purposes hereof, "Stock" shall have the meaning set

          (a)  Definition.   For purposes of this Note, an Event of Default
               ----------

     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
<PAGE>

Company may accept security for this Note or release security for this Note, all
without in any way affecting the liability of Maker hereunder.


          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:

                    ZC Acquisition Corp.
                    1048 Tremont Street
                    Duxbury, MA 02332

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.

     8.   Governing Law.  This Note is made under and governed by the internal
          -------------
law, not the laws of conflicts, of the State of Delaware.

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


          This SENIOR MANAGEMENT AGREEMENT (this "Agreement") is made as of
                                                  ---------
August 17, 1999, between ZEFER Corp., a Delaware corporation (the "Company"),
                                                                   -------
and Gerard E. Dube ("Executive").
                     ---------

          The Company and Executive desire to enter into an agreement pursuant
to which Executive will purchase, and the Company will sell, up to 600,000
shares of the Company's Common Stock, par value $.01 per share (the "Common
                                                                     ------
Stock"). All shares of Common Stock acquired by Executive hereunder are
- -----
referred to herein as "Executive Stock."  In addition, the Company desires to
                       ---------------
employ the Executive and the Executive desires to be employed by the Company.
Certain definitions are set forth in Section 10 of this Agreement.

          The execution and delivery of this Agreement by the Company and
Executive was contemplated as a condition to the purchase of shares of Common
Stock and shares of the Class A Preferred by 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") pursuant to a purchase agreement between the Company and the
- ----------
Investors dated as of March 23, 1999 (the "Purchase Agreement").  Certain
                                           ------------------
provisions of this Agreement are intended for the benefit of, and will be
enforceable by, 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 EXECUTIVE STOCK

          1.   Purchase and Sale of Executive Stock.
               ------------------------------------

          (a)  Upon execution of this Agreement, Executive will purchase, and
the Company will sell, 600,000 shares of Common Stock at a price of $0.17 per
share. To the extent that the fair market value of the common stock exceeds
$0.17 per share, the Company will make a grossed-up "make whole" payment to you
for the amount of taxes due on your purchase as a result of your 83(b) election.
The Company will deliver to Executive the certificates representing such
Executive Stock, and Executive will deliver to the Company a cashier's or
certified check or wire transfer of funds in the aggregate amount of $21,445.50
and a promissory note in the form of Exhibit A attached hereto in an aggregate
                                     ---------
principal amount of $80,554.50 (the "Executive Note").
                                     --------------

          (b)  Within 30 days after the date hereof, Executive will make an
effective election with the Internal Revenue Service under Section 83(b) of the
Internal Revenue Code and the regulations promulgated thereunder in the form of
Exhibit B attached hereto.
- ---------

<PAGE>

          (c)  Until the occurrence of a Sale of the Company or a Public
Offering, all certificates evidencing shares of Executive Stock shall be held by
the Company for the benefit of the Executive and the other holder(s) of
Executive Stock. Upon the occurrence of a Sale of the Company or a Public
Offering, the Company will return the certificates for the Executive Stock to
the record holders thereof.

          (d)  In connection with the purchase and sale of the Executive Stock,
Executive represents and warrants to the Company that:

               (i)   The Executive Stock to be acquired by Executive pursuant to
     this Agreement will be acquired for Executive's own account and not with a
     view to, or intention of, distribution thereof in violation of the
     Securities Act, or any applicable state securities laws, and the Executive
     Stock will not be disposed of in contravention of the Securities Act or any
     applicable state securities laws.

               (ii)  Executive is an executive officer of the Company, is
     sophisticated in financial matters and is able to evaluate the risks and
     benefits of the investment in the Executive Stock.

               (iii) Executive is able to bear the economic risk of her
     investment in the Executive Stock for an indefinite period of time because
     the Executive Stock has not been registered under the Securities Act and,
     therefore, cannot be sold unless subsequently registered under the
     Securities Act or an exemption from such registration is available.

               (iv)  Executive has had an opportunity to ask questions and
     receive answers concerning the terms and conditions of the offering of
     Executive Stock and has had full access to such other information
     concerning the Company as he has requested.

               (v)   This Agreement constitutes the legal, valid and binding
     obligation of Executive, enforceable in accordance with its terms, and the
     execution, delivery and performance of this Agreement by Executive does not
     and will not conflict with, violate or cause a breach of any agreement,
     contract or instrument to which Executive is a party or any judgment, order
     or decree to which Executive is subject.

               (vi)  Executive 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 Executive is a party to or by which
     Executive is bound.

               (vii) Executive is a resident of the State of Massachusetts.

          (e)  As an inducement to the Company to issue the Executive Stock to
Executive, and as a condition thereto, Executive acknowledges and agrees that
neither the issuance of the
<PAGE>

Executive Stock to Executive nor any provision contained herein shall entitle
Executive to remain in the employment of the Company or any of its Subsidiaries
or affect the right of the Company to terminate Executive's employment at any
time for any reason, subject, however, to the terms of this Agreement.

          (f)  Concurrently with the execution of this Agreement, Executive
shall execute in blank ten stock transfer powers in the form of Exhibit C
                                                                ---------
attached hereto (the "Stock Powers") with respect to the Executive 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 Executive Stock to the
appropriate acquiror thereof pursuant to Section 3 below or Section 5 of the
Stockholders Agreement and under no other circumstances.

          2.   Vesting of Executive Stock.
               --------------------------

          (a)  All of the shares of Executive Stock acquired hereunder shall be
subject to vesting in the manner specified in this Section  2.  Except as
otherwise provided in Sections 2(b) and 2(c) below, the Executive  Stock will
become vested in accordance with the following schedule (the "Vesting
                                                              -------
Schedule"), if as of each such date Executive is still employed by the Company

          (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 Executive is still employed by the Company or any
of its Subsidiaries, the Executive Stock will vest as follows:

               (i)   If the Modification Date is June 30, then 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

                                      -3-

<PAGE>

       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

               (iv)  If the Modification Date is March 31, then an additional 5%
       of Executive Stock will vest on each subsequent June 30, September 30,
       December 31 and March 31 so that the Executive Stock will be 100% vested
       on March 31, 2004.

     (c)  Upon the occurrence of a Transaction, all shares of Executive 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 Executive Stock which have become vested
          are referred to herein as "Vested Shares" and all other shares of
                                     -------------
          Executive Stock are referred to herein as "Unvested Shares."
                                                     ---------------

     (d)  In the event that the Executive is separated by the Company without
          Cause or the Executive resigns for Good Reason on or before March 31,
          2000, then 20% of the Executive Stock shall become vested one day
          prior to such separation and, notwithstanding anything herein to the
          contrary, when such 20% of Executive Stock becomes vested under this
          or any other provision of this agreement, such shares shall not be
          subject to the provisions of Section 3 hereof.

               3.   Repurchase Option.
                    -----------------

               (a)  In the event (i) Executive ceases to be employed by the
Company and its Subsidiaries for any reason (the "Separation") or (ii) Executive
                                                  ----------
fails to make any principal or interest payment under the Executive Note after
such payment becomes due and after giving effect to any applicable grace period
(a "Triggering Event"), the Executive Stock (whether held by Executive or one or
    ----------------
more of Executive'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 Executive Stock will be Executive's Original Cost for
such share and (ii) the purchase price for each Vested Share of Executive Stock
will be the Fair Market Value for such share as at the date of the Separation;
provided, however, that if Executive's employment is terminated with Cause, the
- --------  -------
purchase price for each Vested Share of Executive Stock will be Executive'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 Executive Stock (whether a Vested Share or
Unvested Share) will be Executive's Original Cost for such shares.

                                      -4-

<PAGE>

               (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 Executive 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 Executive Stock held by Executive at the time of delivery of the Repurchase
Notice. If the number of shares of Executive Stock then held by Executive is
less than the total number of shares of Executive Stock which the Company has
elected to purchase, the Company shall purchase the remaining shares elected to
be purchased from the other holder(s) of Executive Stock under this Agreement,
pro rata according to the number of shares of Executive Stock held by such other
holder(s) at the time of delivery of such Repurchase Notice (determined as
nearly as practicable to the nearest share). The number of Unvested Shares and
Vested Shares to be repurchased hereunder will be allocated among Executive and
the other holders of Executive Stock (if any) pro rata according to the number
of shares of Executive Stock to be purchased from such person.

               (d)  If for any reason the Company does not elect to purchase all
of the Executive Stock pursuant to the Repurchase Option, all other 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 Executive 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 Executive Stock as to the 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 Executive 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 Executive Stock
to be purchased by each of them.

                                      -5-

<PAGE>

               (e)  The closing of the purchase of the Executive Stock pursuant
to the Repurchase Option shall take place on the date designated by the Company
in the Repurchase Notice or Supplemental Repurchase Notice, which date shall not
be more than one month nor less than five days after the delivery of the later
of either such notice to be delivered. The Company will pay for the Executive
Stock to be repurchased by it pursuant to the Repurchase Option with (i) a check
or wire transfer of funds for (A) any shares of Executive Stock to be
repurchased at Executive's Original Cost and (B) in the case of Executive Stock
to be repurchased at Fair Market Value, that portion of such Executive Stock
which is equal to the Executive's Original Cost, and (ii) in the case of
Executive Stock to be repurchased at Fair Market Value, a subordinate note or
notes for that portion of such Executive Stock which exceeds the Executive'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 Executive to
the Company. Each Senior Manager and each Investor will pay for the Executive
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 Executive Stock.

               (g)  Notwithstanding anything to the contrary contained in this
Agreement, if the Fair Market Value of a share of Executive Stock is finally
determined to be an amount at least 10% greater than the per share repurchase
price for such share of Executive Stock in the Repurchase Notice or in the
Supplemental Repurchase Notice, each of the Company and the Investors shall have
the right to revoke its exercise of the Repurchase Option for all or any portion
of the Executive Stock elected to be repurchased by it by delivering notice of
such revocation in writing to the holders of Executive Stock during the thirty-
day period beginning on the date that the Company and/or the Investors are given
written notice that the Fair Market Value of a share of Executive Stock was
finally determined to be an amount at least 10% greater than the per share
repurchase price for Executive 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 Executive Stock.
                    -------------------------------------------

               (a)  Transfer of Executive Stock. The holder of Executive Stock
                    ---------------------------
shall not Transfer any interest in any shares of Executive Stock, except
pursuant to (i) the provisions of Section 3 hereof, (ii) the provisions of
Section 3 of the Stockholders Agreement (a "Participating Sale"), (iii) an
                                            ------------------
Approved Sale (as defined in Section 5 of the Stockholders Agreement), or (iv)
the provisions

                                      -6-

<PAGE>

of Section 4(b) below.

               (b)  Certain Permitted Transfers. The restrictions in this
                    ---------------------------
Section 4 will not apply with respect to any Transfer of Executive Stock if made
(i) pursuant to applicable laws of descent and distribution or to such Person's
legal guardian in the case of any mental incapacity or among such Person's
Family Group, or (ii) at a time when (A) the Common Stock of the Company has
been trading for at least 45 consecutive days (including the day immediately
preceding such Transfer) at a price that exceeds the initial Public Offering
price by at least 20% and (B) the Common Stock bid and asked price on the day of
such Transfer was at least 20% greater than the initial Public Offering price,
but in the case of this clause (ii) only an amount of shares per calender year
up to the lesser of (x) the number of Vested Shares owned by Executive at the
time of such Transfer and (y) 10% of the total number of shares of Common Stock
owned by Executive at the time of the Company's initial Public Offering, or
(iii) at such time as the Investors sell shares of Common Stock in a Public
Sale, but in the case of this clause (iii) only an amount of shares (the
"Transfer Amount") equal to the lesser of (C) the number of Vested Shares of
 ---------------
Common Stock owned by Executive at the time of such Transfer and (D) the number
of shares of Common Stock owned by Executive multiplied by a fraction (the
"Transfer Fraction"), the numerator of which is the number of shares of Common
 -----------------
Stock sold by the Investors in such Public Sale and the denominator of which is
the total number of shares of Common Stock held by the Investors prior to the
Public Sale; provided that, if at the time of a Public Sale of shares by the
             -------- ----
Investors, Executive chooses not to Transfer the Transfer Amount, Executive
shall retain the right to Transfer an amount of Executive Stock at a future date
equal to the lesser of (x) the number of Vested Shares owned by Executive at
such future date and (y) the number of shares of Executive Stock owned by
Executive at such future date multiplied by the Transfer Fraction; provided
                                                                   --------
further, that at any particular point in time during any given calendar year the
- -------
number of shares of Common Stock which the Executive has a right to Transfer
pursuant to clause (ii) above shall be reduced by the number of shares of Common
Stock which the Executive has Transferred in such calendar year pursuant to
clause (iii) above and the number of shares of Common Stock which the Executive
has a right to Transfer pursuant to clause (iii) above shall be reduced by the
number of shares of Common Stock which the Executive has Transferred in such
calendar year pursuant to clause (ii) above.  Notwithstanding anything in this
Section 4 to the contrary, the  restrictions contained in this Section 4 will
continue to be applicable to the Executive Stock after any Transfer of the type
referred to in clause (i) and the transferees of such Executive Stock will agree
in writing to be bound by the provisions of this Agreement.  Any transferee of
Executive Stock pursuant to a transfer in accordance with the provisions of this
Section 4(b)(i) is herein referred to as a "Permitted Transferee."  Upon the
                                            --------------------
transfer of Executive Stock pursuant to this Section 4(b), the transferring
Executive Stockholder will deliver a written notice (a "Transfer Notice") to the
                                                        ---------------
Company.  In the case of a Transfer pursuant to clause (i) hereof, the Transfer
Notice will disclose in reasonable detail the identity of the Permitted
Transferee(s).  In addition, following the completion of an initial Public
Offering, Executive, in his sole discretion, may pledge up to $2 million worth
of Vested Shares as collateral for a loan so long as the pledgee of such stock
and the Executive enter into a pledge agreement in form and substance reasonably
satisfactory to the Board of Directors of the Company (the "Board"), pursuant to
which pledgee, among other things, agrees that pledgee may only sell such stock
in a Public Sale.

          (c)  Termination of Restrictions. The restrictions set forth in
               ---------------------------
this Section 4 will continue with respect to each share of Executive Stock until
the earlier of (i) the date on which such share of Executive Stock has been
transferred in a Public Sale permitted by this Section 4, or (ii) the
consummation of an Approved Sale.

          5.   Additional Restrictions on Transfer of Executive Stock.
               ------------------------------------------------------

          (a)  Legend.  The certificates representing the Executive Stock will
               ------
bear a legend in substantially the following form:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ORIGINALLY
     ISSUED AS OF AUGUST 17, 1999, HAVE NOT BEEN REGISTERED UNDER THE
     SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT BE
     SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
     STATEMENT UNDER THE ACT OR AN EXEMPTION FROM REGISTRATION
     THEREUNDER. THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE
     ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER, CERTAIN
     REPURCHASE OPTIONS AND CERTAIN OTHER AGREEMENTS SET FORTH IN A
     SENIOR MANAGEMENT AGREEMENT BETWEEN THE COMPANY AND AN EXECUTIVE
     OF THE COMPANY DATED AS OF AUGUST 17, 1999. A COPY OF SUCH
     AGREEMENT MAY BE OBTAINED BY THE HOLDER HEREOF AT THE COMPANY'S
     PRINCIPAL PLACE OF BUSINESS WITHOUT CHARGE."

          (b)  Opinion of Counsel.  No holder of Executive Stock may sell,
               ------------------
transfer or dispose of any Executive Stock (except pursuant to an effective
registration statement under the Securities Act) without first delivering to the
Company an 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 Executive Stock delivers to the
Company an opinion of counsel that no subsequent transfer of such Executive
Stock shall require registration under the Securities Act, the Company shall
promptly upon such contemplated transfer deliver new certificates for such
Executive 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 Executive 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.

     previously paid (the obligations set forth in clauses (A) and (B) are
     collectively referred to herein as the "Accrued Obligations");
                                             -------------------

               (ii)  the Company shall pay each month to the Executive,
     beginning on the date of the first normal executive payroll of the Company
     that occurs more than 30 days after such termination or resignation, an

     of the date immediately before such termination or resignation; provided
                                                                     --------
     however, that such payments shall immediately cease upon the earliest to
     -------
     occur of (x) the Executive's death and (y) the six month anniversary of
     such termination or resignation. Notwithstanding anything in this Section
     6(d) to the contrary, in the event that the Executive becomes employed with
     another employer, then the payments to be made by the Company pursuant to
     this Section 6(d)(ii) shall be reduced (on a dollar for dollar basis) in an
     amount equal to the cash compensation received by Executive from such
     employer; and

               (iii) the Company shall continue to provide medical insurance
     benefits to the Executive and to the Executive's family at least equal to
     those medical insurance benefits that would have been provided to them in
     the absence of such termination or resignation; provided however, that such
                                                     -------- -------
     payments shall immediately cease upon the earliest to occur of (x) the
     Executive's death and (y) the six month anniversary of such termination or
     resignation.  Notwithstanding anything in this Section 6(d) to the
     contrary, in the event that the Executive becomes employed with another
     employer and is eligible for medical insurance benefits under another
     employer-provided plan, then the medical insurance benefits to be provided
     by the Company pursuant to this Section 6(d)(iii) shall be reduced to the
     extent that the Executive and his/her family is eligible to receive medical
     insurance benefits under such other employer-provided plan.

          (e)  Other Separations.  In the event of a Separation other than a
               -----------------
termination by the Company without cause or a resignation by the Executive for
Good Reason, the Company shall pay to the Executive (or his/her estate, if
applicable), in a lump sum in cash within 15 days after such Separation, an
amount equal to any Accrued Obligations.

          7.   Confidential Information. Executive acknowledges that the
               ------------------------
information, observations and data obtained by him during the course of his/her
performance under this Agreement concerning the business and affairs of the
Company and its affiliates are the property of the Company, including
information concerning acquisition opportunities in or reasonably related to the
Company's business or industry of which Executive becomes aware during the
Employment Period. Therefore, Executive agrees that he will not disclose to any
unauthorized person or use for his/her own account any of such information,
observations or data without the Company's written consent, unless and to the
extent that the aforementioned matters become generally known to and available
for use by the public other than as a result of Executive's acts or omissions to
act. Executive agrees to deliver to the Company at a Separation, or at any other
time the Company may request in writing, all memoranda, notes, plans, records,
reports and other documents (and copies thereof) relating to the business of the
Company and its affiliates (including, without limitation, all

                                     -10-

<PAGE>

acquisition prospects, lists and contact information) which he may then possess
or have under his/her control.

          8.   Noncompetition and Nonsolicitation. Executive acknowledges that
               ----------------------------------
in the course of his/her employment with the Company he will become familiar
with the Company's and its Subsidiaries' trade secrets and with other
confidential information concerning the Company and such Subsidiaries and that
his/her services will be of special, unique and extraordinary value to the
Company. Therefore, Executive agrees that:

          (a)  Noncompetition.  During the Employment Period and for a period of
               --------------
six months thereafter (the "Noncompete Period"), Executive shall not, within the
                            -----------------
United States, directly or indirectly own, manage, control, participate in,
consult with, render services for, or in any manner engage in any internet
services business which directly competes with the business of the Company or
its Subsidiaries or any business in which the Company or any of its Subsidiaries
has requested and received information relating to the acquisition of such
business by the Company and the Subsidiaries prior to the Separation; provided
                                                                      --------
that passive ownership of less than 5% of the outstanding stock of any publicly-
traded corporation shall not, in and of itself, be deemed to violate this
Section 8(a).

          (b)  Nonsolicitation.  During the Noncompete Period, Executive shall
               ---------------
not directly or indirectly through another entity (i) induce or attempt to
induce any employee of the Company or its Subsidiaries to leave the employ of
the Company or such Subsidiary, or in any way interfere with the relationship
between the Company and any Subsidiary and any employee thereof, (ii) hire any
person who was an employee of the Company and any Subsidiary within 180 days
prior to the time such employee was hired by the Executive, (iii) induce or
attempt to induce any customer, supplier, licensee or other business relation of
the Company and any Subsidiary to cease doing business with the Company or such
Subsidiary or in any way interfere with the relationship between any such
customer, supplier, licensee or business relation and the Company and any
Subsidiary or (iv) directly or indirectly acquire or attempt to acquire an
interest in any business relating to the business of the Company and any
Subsidiary and with which the Company and any Subsidiary has entertained
discussions or has requested and received information relating to the
acquisition of such business by the Company and any Subsidiary in the two-year
period immediately preceding a Separation.

          (c)  Enforcement.  If, at the time of enforcement of Section 7 or this
               -----------
Section 8, a court holds that the restrictions stated herein are unreasonable
under circumstances then existing, the parties hereto agree that the maximum
duration, scope or geographical area reasonable under such circumstances shall
be substituted for the stated period, scope or area and that the court shall be
allowed to revise the restrictions contained herein to cover the maximum
duration, scope and area permitted by law.  Because Executive's services are
unique and because Executive has access to confidential information, the parties
hereto agree that money damages would be an inadequate remedy for any breach of
this Agreement.  Therefore, in the event a breach or threatened breach of this
Agreement, the Company or its successors or assigns may, in addition to other
rights and remedies existing in their favor, apply to any court of competent
jurisdiction for specific performance

                                     -11-

<PAGE>

and/or injunctive or other relief in order to enforce, or prevent any violations
of, the provisions hereof (without posting a bond or other security).

          (d)  Additional Acknowledgments.  Executive acknowledges that the
               --------------------------
provisions of this Section 8 are in consideration of:  (i) employment with the
Company, (ii) the issuance of the Executive Stock and (iii) additional good and
valuable consideration as set forth in this Agreement.  In addition, Executive
agrees and acknowledges that the restriction contained in Section 7 and this
Section 8 do not preclude Executive from earning a livelihood, nor do they
unreasonably impose limitations on Executive's ability to earn a living.  In
addition, Executive agrees and acknowledges that the potential harm to the
Company of the non-enforcement of Section 7 and this Section 8 outweighs any
potential harm to Executive of its enforcement by injunction or otherwise.
Executive acknowledges that he has carefully read this Agreement and has given
careful consideration to the restraints imposed upon Executive by this
Agreement, and is in full accord as to their necessity for the reasonable and
proper protection of confidential and proprietary information of the Company now
existing or to be developed in the future.  Executive expressly acknowledges and
agrees that each and every restraint imposed by this Agreement is reasonable
with respect to subject matter, time period and geographical area.

the Fair Market Value is being determined and the 20 consecutive business days

Fair Market Value shall be determined by an appraiser jointly selected by the
Board and the Executive, which appraiser shall submit to the Board and the
Executive a report within 30 days of its engagement setting forth such
determination. If the parties are unable to agree on an appraiser within 45 days
after delivery of the Repurchase Notice or the Supplemental Repurchase Notice,
within seven days, each party shall submit the names of four nationally
recognized investment banking firms, and each party shall be entitled to strike
two names from the other party's list of firms, and the appraiser shall be
selected by lot from the remaining four investment banking firms. The expenses
of such appraiser shall be borne by the party whose Fair Market Value
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.

provision or any other jurisdiction, but this Agreement will be reformed,

               ------------------
referred to herein and other documents of even date herewith embody the complete

that would cause the application of the laws of any jurisdiction other than the
State of Delaware.

          (h)  Remedies.  Each of the parties to this Agreement (including the
               --------
Investors) will be entitled to enforce its rights under this Agreement
specifically, to recover damages and costs (including attorney's fees) caused by

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 generally accepted
accounting principles, consistently applied, except that if because of a change
in generally accepted accounting principles the Company would have to alter a
previously utilized accounting method or policy in order to remain in compliance
with generally accepted accounting principles, 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

(o)  Deemed Transfer of Executive Stock. If the Company (and/or the Investors
     ----------------------------------
and/or any other Person acquiring securities) shall make available, at the time
and place and in the amount and form provided in this Agreement, the

provisions of this Agreement, then from and after such time, the person from
whom such shares are to be repurchased shall no longer have any rights as a
holder of such shares (other than the right to receive payment of such
consideration in accordance with this Agreement), and such shares shall be
deemed purchased in accordance with the applicable provisions hereof and the

shall be deemed the owner and holder of such shares, whether or not the
certificates therefor have been delivered as required by this Agreement.

          (p)  No Pledge or Security Interest.  The purpose of the Company's
               ------------------------------

does not constitute a pledge by the Executive of, or the granting of a security
interest in, the underlying stock.

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

August 17, 1999                                                       $80,554.50



          Gerard E. Dube ("Maker"), hereby promises to pay to the order of ZEFER
                           -----
Corp. (the "Company"), the principal amount of $80,554.50 together with interest
            -------
thereon calculated from the date hereof in accordance with the provisions of
this Note.

          This Note is the Executive Note referred to in the Senior Management
Agreement, dated as of the date hereof, between the Company and Maker (the
"Management Agreement").  Section 1(a) of the Management Agreement contains
- ---------------------
provisions for the issuance of this Note upon the terms and conditions specified
herein.  Capitalized terms used herein and not otherwise defined shall have the
meanings given to them in the Management Agreement.

     1.  Interest.  Interest shall accrue on the outstanding principal amount of
         --------
this Note at a rate equal to the lesser of (i) 5% per annum or (ii) the highest
rate permitted by applicable law, compounded annually on each anniversary of the
date hereof.

     2.      Payment on Note.
             ---------------

         (a) Term.  Subject to Section 2(b) below, the entire principal amount
             ----
of this Note and all accrued interest thereon shall be due and payable on the
fifth anniversary of the date hereof.

         (b) Mandatory Prepayments.  Notwithstanding anything in Section 2(a)
             ---------------------
to the contrary, Maker shall make the following mandatory prepayments:

             (i)    Upon the purchase of Stock from time to time by the
     Investors pursuant to Section 1B(b) of the Purchase Agreement dated March
     23, 1999 by and among the Company and the Investors, as amended from time
     to time (the "Purchase Agreement"), Maker shall make a payment of principal
                   ------------------
     in an amount equal to the product of (A) $102,000 multiplied by (B) the

     quotient of (x) the amount paid to the Company in connection with such
     purchase of Stock by Investors, divided by (y) $100,000,000, plus all
                                     ------- --
     accrued interest on such principal amount (or such lesser principal amount
     then outstanding). For purposes hereof, "Stock" shall have the meaning set
                                              -----
     forth in the Purchase Agreement.

     to any accrued interest and second, to any principal then outstanding. Upon
                                 ------

             --------------------
time without premium or penalty, prepay all of the outstanding principal amount
of the Note; provided that any prepayment will be accompanied by a payment of
accrued interest on the portion being prepaid.

         (d) Right of Offset.  Upon an Event of Default (as described in
             ---------------

     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.

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.
<PAGE>

     Maker, or his/her 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.

          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.

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

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.

in excess of the maximum legal amount allowed under the applicable usury laws as

Stock and shares of the Class A Preferred by GTCR Fund VI, L.P., a Delaware
limited partnership ("GTCR"), GTCR VI Executive Fund, L.P., a Delaware limited

          (a)  Upon execution of this Agreement, Executive will purchase, and
the Company will sell, 105,000 shares of Common Stock at a price of $.50 per
share. The Company will deliver to Executive the certificates representing such
Executive Stock, and Executive will deliver to the Company a cashier's or
certified check or wire transfer of funds in the aggregate amount of $4,606.88
and a promissory note in the form of Exhibit A attached hereto in an aggregate
                                     ---------
principal amount of $47,893.13 (the "Executive Note").
                                     --------------

          (b)  Within 30 days after the date hereof, Executive will make an
effective election with the Internal Revenue Service under Section 83(b) of the
Internal Revenue Code and the regulations promulgated thereunder in the form of
Exhibit B attached hereto.
- ---------
<PAGE>

          (c)  Until the occurrence of a Sale of the Company or a Public
Offering, all certificates evidencing shares of Executive Stock shall be held by
the Company for the benefit of the Executive and the other holder(s) of
Executive Stock.  Upon the occurrence of a Sale of the Company or a Public
Offering, the Company will return the certificates for the Executive Stock to
the record holders thereof.

          (d)  In connection with the purchase and sale of the Executive Stock,
Executive represents and warrants to the Company that:

               (i)   The Executive Stock to be acquired by Executive pursuant to
     this Agreement will be acquired for Executive's own account and not with a
     view to, or intention of, distribution thereof in violation of the
     Securities Act, or any applicable state securities laws, and the Executive
     Stock will not be disposed of in contravention of the Securities Act or any
     applicable state securities laws.

               (ii)  Executive is an executive officer of the Company, is
     sophisticated in financial matters and is able to evaluate the risks and
     benefits of the investment in the Executive Stock.

               (iii) Executive is able to bear the economic risk of his
     investment in the Executive Stock for an indefinite period of time because
     the Executive Stock has not been registered under the Securities Act and,
     therefore, cannot be sold unless subsequently registered under the
     Securities Act or an exemption from such registration is available.

               (iv)  Executive has had an opportunity to ask questions and
     receive answers concerning the terms and conditions of the offering of
     Executive Stock and has had full access to such other information
     concerning the Company as he has requested.

               (v)   This Agreement constitutes the legal, valid and binding
     obligation of Executive, enforceable in accordance with its terms, and the
     execution, delivery and performance of this Agreement by Executive does not
     and will not conflict with, violate or cause a breach of any agreement,
     contract or instrument to which Executive is a party or any judgment, order
     or decree to which Executive is subject.

               (vi)  Executive 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 Executive is a party to or by which
     Executive is bound.

               (vii) Executive is a resident of the State of Massachusetts.

          (e)  As an inducement to the Company to issue the Executive Stock to
Executive, and as a condition thereto, Executive acknowledges and agrees that
neither the issuance of the

                                      -2-
<PAGE>

Executive Stock to Executive nor any provision contained herein shall entitle
Executive to remain in the employment of the Company or any of its Subsidiaries
or affect the right of the Company to terminate Executive's employment at any
time for any reason, subject, however, to the terms of this Agreement.

          (f)  Concurrently with the execution of this Agreement, (i) Executive
shall execute in blank ten stock transfer powers in the form of Exhibit C
                                                                ---------
attached hereto (the "Stock Powers") with respect to the Executive 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 Executive
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
Executive's spouse shall execute the consent in the form of Exhibit D attached

          (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 Executive is still employed by the Company or any
of its Subsidiaries, the Executive 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%

                                      -3-
<PAGE>

     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 Executive Stock will vest on each subsequent June 30, September 30,
     December 31 and March 31 so that the Executive Stock will be 100% vested on
     March 31, 2004.

     (c)  Upon the occurrence of a Transaction, all shares of Executive 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 Executive Stock which have become vested
          are referred to herein as "Vested Shares" and all other shares of
                                     -------------
          Executive Stock are referred to herein as "Unvested Shares."
                                                     ---------------

          3.   Repurchase Option.
               -----------------

          (a)  In the event (i) Executive ceases to be employed by the Company
and its Subsidiaries for any reason (the "Separation") or (ii) Executive fails
                                          ----------
to make any principal or interest payment under the Executive Note after such
payment becomes due and after giving effect to any applicable grace period (a
"Triggering Event"), the Executive Stock (whether held by Executive or one or
 ----------------
more of Executive'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 Executive Stock will be Executive's Original Cost for such
share and (ii) the purchase price for each Vested Share of Executive Stock will
be the Fair Market Value for such share as at the date of the Separation;
provided, however, that if Executive's employment is terminated with Cause, the
- --------  -------
purchase price for each Vested Share of Executive Stock will be Executive'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 Executive Stock (whether a Vested Share or
Unvested Share) will be Executive'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 Executive 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

                                      -4-
<PAGE>

holder, the aggregate consideration to be paid for such shares and the time and
place for the closing of the transaction.  The number of shares to be
repurchased by the Company shall first be satisfied to the extent possible from
the shares of Executive Stock held by Executive at the time of delivery of the
Repurchase Notice.  If the number of shares of Executive Stock then held by
Executive is less than the total number of shares of Executive Stock which the
Company has elected to purchase, the Company shall purchase the remaining shares
elected to be purchased from the other holder(s) of Executive Stock under this
Agreement, pro rata according to the number of shares of Executive Stock held by
such other holder(s) at the time of delivery of such Repurchase Notice
(determined as nearly as practicable to the nearest share).  The number of
Unvested Shares and Vested Shares to be repurchased hereunder will be allocated
among Executive and the other holders of Executive Stock (if any) pro rata
according to the number of shares of Executive Stock to be purchased from such
person.

          (d)  If for any reason the Company does not elect to purchase all of
the Executive Stock pursuant to the Repurchase Option, all other 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 Executive 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
Executive Stock as to the 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 Executive 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 Executive Stock to be purchased by each of them.

          (e)  The closing of the purchase of the Executive Stock pursuant to
the Repurchase Option shall take place on the date designated by the Company in
the Repurchase Notice

                                      -5-
<PAGE>

or Supplemental Repurchase Notice, which date shall not be more than one month
nor less than five days after the delivery of the later of either such notice to
be delivered. The Company will pay for the Executive Stock to be repurchased by
it pursuant to the Repurchase Option with (i) a check or wire transfer of funds
for (A) any shares of Executive Stock to be repurchased at Executive's Original
Cost and (B) in the case of Executive Stock to be repurchased at Fair Market
Value, that portion of such Executive Stock which is equal to the Executive's
Original Cost, and (ii) in the case of Executive Stock to be repurchased at Fair
Market Value, a subordinate note or notes for that portion of such Executive
Stock which exceeds the Executive'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 Executive to the Company. Each Senior Manager
and each Investor will pay for the Executive 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 Executive Stock.

          (f)  Notwithstanding anything to the contrary contained in this
Agreement, all repurchases of Executive Stock by the Company shall be subject to
applicable restrictions contained in the Delaware General Corporation Law and in
the Company's and its Subsidiaries' debt and equity financing agreements.  If
any such restrictions prohibit the repurchase of Executive Stock hereunder which
the Company is otherwise entitled or required to make, the Company may make such
repurchases as soon as it is permitted to do so under such restrictions.

          (g)  Notwithstanding anything to the contrary contained in this
Agreement, if the Fair Market Value of a share of Executive Stock is finally
determined to be an amount at least 10% greater than the per share repurchase
price for such share of Executive Stock in the Repurchase Notice or in the
Supplemental Repurchase Notice, each of the Company and the Investors shall have
the right to revoke its exercise of the Repurchase Option for all or any portion
of the Executive Stock elected to be repurchased by it by delivering notice of
such revocation in writing to the holders of Executive Stock during the thirty-
day period beginning on the date that the Company and/or the Investors are given
written notice that the Fair Market Value of a share of Executive Stock was
finally determined to be an amount at least 10% greater than the per share
repurchase price for Executive 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 Executive Stock.

<PAGE>

          (a)  Transfer of Executive Stock.  The holder of Executive Stock shall
               ---------------------------
not Transfer any interest in any shares of Executive Stock, except pursuant to

Stockholders Agreement (a "Participating Sale"), (iii) an Approved Sale (as
                           ------------------
defined in Section 5 of the Stockholders Agreement), or (iv) the provisions of
Section 4(b) below.

          (b)  Certain Permitted Transfers.  The restrictions in this Section 4
               ---------------------------
will not apply with respect to any Transfer of Executive Stock if made (i)
pursuant to applicable laws of descent and distribution or to such Person's
legal guardian in the case of any mental incapacity or among such Person's
Family Group, or (ii) at a time when (A) the Common Stock of the Company has
been trading for at least 45 consecutive days (including the day immediately
preceding such Transfer) at a price that exceeds the initial Public Offering

time of such Transfer and (y) 10% of the total number of shares of Common Stock
owned by Executive at the time of the Company's initial Public Offering, or
(iii) at such time as the Investors sell shares of Common Stock in a Public

"Transfer Amount") equal to the lesser of (C) the number of Vested Shares of
 ---------------
Common Stock owned by Executive at the time of such Transfer and (D) the number

"Transfer Fraction"), the numerator of which is the number of shares of Common
 -----------------
Stock sold by the Investors in such Public Sale and the denominator of which is
the total number of shares of Common Stock held by the Investors prior to the
Public Sale; provided that, if at the time of a Public Sale of shares by the
             -------- ----
Investors, Executive chooses not to Transfer the Transfer Amount, Executive
shall retain the right to Transfer an amount of Executive Stock at a future date
equal to the lesser of (x) the number of Vested Shares owned by Executive at
such future date and (y) the number of shares of Executive Stock owned by
Executive at such future date multiplied by the Transfer Fraction; provided
                                                                   --------
further, that at any particular point in time during any given calendar year the
- -------
number of shares of Common Stock which the Executive has a right to Transfer
pursuant to clause (ii) above shall be reduced by the number of shares of Common
Stock which the Executive has Transferred in such calendar year pursuant to
clause (iii) above and the number of shares of Common Stock which the Executive
has a right to Transfer pursuant to clause (iii) above shall be reduced by the
number of shares of Common Stock which the Executive has Transferred in such
calendar year pursuant to clause (ii) above.  Notwithstanding anything in this
Section 4 to the contrary, the  restrictions contained in this Section 4 will
continue to be applicable to the Executive Stock after any Transfer of the type
referred to in clause (i) and the transferees of such Executive Stock will agree
in writing to be bound by the provisions of this Agreement.  Any transferee of
Executive Stock pursuant to a transfer in accordance with the provisions of this
Section 4(b)(i) is herein referred to as a "Permitted Transferee."  Upon the
                                            --------------------
transfer of Executive Stock pursuant to this Section 4(b), the transferring
Executive Stockholder will deliver a written notice (a "Transfer Notice") to the
                                                        ---------------
Company.  In the case of a Transfer pursuant to clause (i) hereof, the Transfer
Notice will disclose in reasonable detail the identity of the Permitted
Transferee(s).  In addition, following

Directors of the Company (the "Board"), pursuant to which pledgee, among other
things, agrees that pledgee may only sell such stock in a Public Sale.

          (c)  Termination of Restrictions.  The restrictions set forth in this
               ---------------------------
Section 4 will continue with respect to each share of Executive Stock until the

          5.   Additional Restrictions on Transfer of Executive Stock.
               ------------------------------------------------------

          (a)  Legend.  The certificates representing the Executive Stock will
               ------
bear a legend in substantially the following form:

               "THE SECURITIES REPRESENTED BY THIS CERTIFICATE 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  SOLD OR TRANSFERRED IN THE
                     ---
               ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
               ACT OR AN EXEMPTION FROM REGISTRATION THEREUNDER. THE
               SECURITIES REPRESENTED BY THIS CERTIFICATE ARE ALSO
               SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER, CERTAIN
               REPURCHASE OPTIONS AND CERTAIN OTHER AGREEMENTS SET FORTH
               IN A SENIOR MANAGEMENT AGREEMENT BETWEEN THE COMPANY AND

               COPY OF SUCH AGREEMENT MAY BE OBTAINED BY THE HOLDER
               HEREOF AT THE COMPANY'S PRINCIPAL PLACE OF BUSINESS
               WITHOUT CHARGE."

          (b)  Opinion of Counsel.  No holder of Executive Stock may sell,
               ------------------
transfer or dispose of any Executive Stock (except pursuant to an effective
registration statement under the Securities Act) without first delivering to the
Company an 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 Executive Stock delivers to the
Company an opinion of counsel that no subsequent transfer of such Executive
Stock shall require registration under the Securities Act, the Company shall
promptly upon such contemplated transfer deliver new certificates for such
Executive Stock which

                                      -8-
<PAGE>

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 Executive
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.

applicable), in a lump sum in cash within 15 days after such Separation, an
amount equal to any Accrued Obligations.

          7.  Confidential Information.  Executive acknowledges that the
              ------------------------
information,

                                      -10-
<PAGE>

observations and data obtained by him during the course of his performance under
this Agreement concerning the business and affairs of the Company and its
affiliates are the property of the Company, including information concerning
acquisition opportunities in or reasonably related to the Company's business or
industry of which Executive becomes aware during the Employment Period.
Therefore, Executive agrees that he will not disclose to any unauthorized person
or use for his own account any of such information, observations or data without
the Company's written consent, unless and to the extent that the aforementioned
matters become generally known to and available for use by the public other than
as a result of Executive's acts or omissions to act.  Executive agrees to
deliver to the Company at a Separation, or at any other time the Company may
request in writing, all memoranda, notes, plans, records, reports and other
documents (and copies thereof) relating to the business of the Company and its
affiliates (including, without limitation, all acquisition prospects, lists and
contact information) which he may then possess or have under his control.

          8.   Noncompetition and Nonsolicitation.   Executive acknowledges that
               ----------------------------------
in the course of his employment with the Company he will become familiar with
the Company's and its Subsidiaries' trade secrets and with other confidential
information concerning the Company and such Subsidiaries and that his services
will be of special, unique and extraordinary value to the Company. Therefore,
Executive agrees that:

          (a)  Noncompetition.  During the Employment Period and for a period of
               --------------
one year thereafter (the "Noncompete Period"), Executive shall not, within the
                          -----------------
United States, directly or indirectly own, manage, control, participate in,
consult with, render services for, or in any manner engage in any business
competing with the businesses of the Company or its Subsidiaries or any business
in which the Company or any of its Subsidiaries has requested and received
information relating to the acquisition of such business by the Company and the
Subsidiaries prior to the Separation; provided that passive ownership of less
than 5% of the outstanding stock of any publicly-traded corporation shall not,
in and of itself, be deemed to violate this Section 8(a); provided further that
                                                          --------
if the Executive's Employment with the Company is terminated by the Company
without Cause or the Executive resigns for Good Reason within a twenty four
month period a following a Sale of the Company, the one year period referenced
above shall be shortened to a six month period.

          (b)  Nonsolicitation.  During the Noncompete Period, Executive shall
               ---------------
not directly or indirectly through another entity (i) induce or attempt to
induce any employee of the Company or its Subsidiaries to leave the employ of
the Company or such Subsidiary, or in any way interfere with the relationship
between the Company and any Subsidiary and any employee thereof, (ii) hire any
person who was an employee of the Company and any Subsidiary within 180 days
prior to the time such employee was hired by the Executive, (iii) induce or
attempt to induce any customer, supplier, licensee or other business relation of
the Company and any Subsidiary to cease doing business with the Company or such
Subsidiary or in any way interfere with the relationship between any such
customer, supplier, licensee or business relation and the Company and any
Subsidiary or (iv) directly or indirectly acquire or attempt to acquire an
interest in any business relating to the

                                      -11-
<PAGE>

business of the Company and any Subsidiary and with which the Company and any
Subsidiary has entertained discussions or has requested and received information
relating to the acquisition of such business by the Company and any Subsidiary
in the two-year period immediately preceding a Separation.

          (c)  Enforcement.  If, at the time of enforcement of Section 7 or this
               -----------
Section 8, a court holds that the restrictions stated herein are unreasonable
under circumstances then existing, the parties hereto agree that the maximum
duration, scope or geographical area reasonable under such circumstances shall
be substituted for the stated period, scope or area and that the court shall be
allowed to revise the restrictions contained herein to cover the maximum
duration, scope and area permitted by law.  Because Executive's services are
unique and because Executive has access to confidential information, the parties
hereto agree that money damages would be an inadequate remedy for any breach of
this Agreement.  Therefore, in the event a breach or threatened breach of this
Agreement, the Company or its successors or assigns may, in addition to other
rights and remedies existing in their favor, apply to any court of competent
jurisdiction for specific performance and/or injunctive or other relief in order
to enforce, or prevent any violations of, the provisions hereof (without posting
a bond or other security).

          (d)  Additional Acknowledgments.  Executive acknowledges that the
               --------------------------
provisions of this Section 8 are in consideration of: (i) employment with the
Company, (ii) the issuance of the Executive Stock and (iii) additional good and
valuable consideration as set forth in this Agreement. In addition, Executive
agrees and acknowledges that the restriction contained in Section 7 and this
Section 8 do not preclude Executive from earning a livelihood, nor do they
unreasonably impose limitations on Executive's ability to earn a living. In
addition, Executive agrees and acknowledges that the potential harm to the
Company of the non-enforcement of Section 7 and this Section 8 outweighs any
potential harm to Executive of its enforcement by injunction or otherwise.
Executive acknowledges that he has carefully read this Agreement and has given
careful consideration to the restraints imposed upon Executive by this
Agreement, and is in full accord as to their necessity for the reasonable and
proper protection of confidential and proprietary information of the Company now
existing or to be developed in the future. Executive expressly acknowledges and
agrees that each and every restraint imposed by this Agreement is reasonable
with respect to subject matter, time period and geographical area.

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, dated as of March 23, 1999, by and among the Company, the Investors,
the Executive and certain other stockholders), upon receipt of an undertaking by
or on behalf of the Executive to repay such amount if it shall ultimately be

          (b)  Transfers in Violation of Agreement.  Any Transfer or attempted
               -----------------------------------
Transfer of any Executive Stock in violation of any provision of this Agreement
shall be void, and the Company shall not record such Transfer on its books or
treat any purported transferee of such Executive Stock as the owner of such
stock for any purpose.

          (c)  Severability. Whenever possible, each provision of this Agreement
               ------------
will be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Agreement is held to be invalid, illegal or
unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or any other jurisdiction, but this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

          (d)  Complete Agreement.  This Agreement, those documents expressly
               ------------------
referred to herein and other documents of even date herewith embody the complete

               -------------
concerning the relative rights of the Company and its stockholders and all other
questions concerning the construction, validity and interpretation of this
Agreement, without giving effect to any choice of

<PAGE>

law or other conflict of law provision or rule (whether of the State of Delaware
or any other jurisdiction) that would cause the application of the laws of any
jurisdiction other than the State of Delaware.

          (h)  Remedies.  Each of the parties to this Agreement (including the
               --------
Investors) will be entitled to enforce its rights under this Agreement
specifically, to recover damages and costs (including attorney's fees) caused by
any breach of any provision of this Agreement and to exercise all other rights
existing in its favor.  The parties hereto agree and acknowledge that money
damages may not be an adequate remedy for any breach of the provisions of this
Agreement and that any party may in its sole discretion apply to any court of
law or equity of competent jurisdiction (without posting any bond or deposit)
for specific performance and/or other injunctive relief in order to enforce or
prevent any violations of the provisions of this Agreement.

on Executive in any amount or amounts considered available.  Executive agrees to
cooperate in any medical or other examination, supply any information, and to
execute and deliver any applications or other instruments in writing as may be
reasonably necessary to obtain and constitute such insurance.  Executive hereby
represents that he has no reason to believe that his life is not insurable at
rates now prevailing for healthy men of his age.

          (k)  Business Days.  If any time period for giving notice or taking
               -------------
action hereunder expires on a day which is a Saturday, Sunday or holiday in the

shall be automatically extended to the business day immediately following such

7) shall survive a Separation and shall remain in full force and effect after

          (n)  Generally Accepted Accounting Principles; Adjustments of Numbers.
               ----------------------------------------------------------------
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 generally accepted
accounting principles, consistently applied, except that if because of a change
in generally accepted accounting principles the Company would have to alter a
previously utilized accounting method or policy in order to remain in compliance
with generally accepted accounting principles, 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.

          (o)  Deemed Transfer of Executive Stock.  If the Company (and/or the
               ----------------------------------
Investors and/or any other Person acquiring securities) shall make available, at
the time and place and in the amount and form provided in this Agreement, the
consideration for the Executive Stock to be repurchased in accordance with the
provisions of this Agreement, then from and after such time, the person from
whom such shares are to be repurchased shall no longer have any rights as a
holder of such shares (other than the right to receive payment of such
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.

          (p)  No Pledge or Security Interest.  The purpose of the Company's
               ------------------------------
retention of the Executive's stock certificates and executed stock powers is
solely to facilitate the repurchase provisions set forth in Section 3 herein and
does not constitute a pledge by the Executive of, or the granting of a security
interest in, the underlying stock.

          (q)  Rights Granted to GTCR and its Affiliates.  Any rights granted to
               -----------------------------------------
GTCR and its Affiliates hereunder may also be exercised (in whole or in part) by
its designees (which may be Affiliates).

May 21, 1999                                                          $47,893.13


          Sean W. Mullaney ("Maker"), hereby promises to pay to the order of
                             -----
ZEFER Corp. (the "Company"), the principal amount of $47,893.13 together with
                  -------
interest thereon calculated from the date hereof in accordance with the

 --------------------
provisions for the issuance of this Note upon the terms and conditions specified
herein.  Capitalized terms used herein and not otherwise defined shall have the
meanings given to them in the Management Agreement.

     1.   Interest. Interest shall accrue on the outstanding principal amount of
          --------
this Note at a rate equal to the lesser of (i) 5% per annum or (ii) the highest
rate permitted by applicable law, compounded annually on each anniversary of the
date hereof.

     2.   Payment on Note.
          ---------------

          (a)  Term. Subject to Section 2(b) below, the entire principal amount
               ----
of this Note and all accrued interest thereon shall be due and payable on the
fifth anniversary of the date hereof.

          (b)  Mandatory Prepayments. Notwithstanding anything in Section 2(a)
               ---------------------
to the contrary, Maker shall make the following mandatory prepayments:

               (i)  Upon the purchase of Stock from time to time by the
     Investors pursuant to Section 1B(b) of the Purchase Agreement dated March
     23, 1999 by and among the Company and the Investors, as amended from time
     to time (the "Purchase Agreement"), Maker shall make a payment of principal
                   ------------------
     in an amount equal to the product of (A) $52,500.00, multiplied by (B) the

     purchase of Stock by Investors, divided by (y) $100,000,000, plus all
                                     ------- --
     accrued interest on such principal amount (or such lesser principal amount
     then outstanding). For purposes hereof, "Stock" shall have the meaning set

     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.

portion of the outstanding principal amount of the Note (together with all
accrued interest thereon and all other amounts due in connection therewith) due

<PAGE>

          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.

          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.
               105 South Street
               Boston, MA 02111

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.

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

provisions of this Agreement are intended for the benefit of, and will be

          In consideration of the mutual covenants and promises contained herein
and other good and valuable consideration, the receipt and sufficiency of which

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

          (a)  Upon execution of this Agreement, Executive will purchase, and
the Company will sell, 300,000 shares of Common Stock at a price of $0.34 per
share. The Company will deliver to Executive the certificates representing such
Executive Stock, and Executive will deliver to the Company a cashier's or
certified check or wire transfer of funds in the aggregate amount of $27,195.48
and a promissory note in the form of Exhibit A attached hereto in an aggregate
                                     ---------
principal amount of $74,804.52 (the "Executive Note").
                                     --------------

          (b)  Within 30 days after the date hereof, Executive will make an
effective election with the Internal Revenue Service under Section 83(b) of the
Internal Revenue Code and the regulations promulgated thereunder in the form of
Exhibit B attached hereto.
- ---------
<PAGE>

          (c)  Until the occurrence of a Sale of the Company or a Public
Offering, all certificates evidencing shares of Executive Stock shall be held by
the Company for the benefit of the Executive and the other holder(s) of
Executive Stock. Upon the occurrence of a Sale of the Company or a Public
Offering, the Company will return the certificates for the Executive Stock to
the record holders thereof.

          (d)  In connection with the purchase and sale of the Executive Stock,
Executive represents and warrants to the Company that:

               (i)   The Executive Stock to be acquired by Executive pursuant to
     this Agreement will be acquired for Executive's own account and not with a
     view to, or intention of, distribution thereof in violation of the
     Securities Act, or any applicable state securities laws, and the Executive
     Stock will not be disposed of in contravention of the Securities Act or any
     applicable state securities laws.

               (ii)  Executive is an executive officer of the Company, is
     sophisticated in financial matters and is able to evaluate the risks and
     benefits of the investment in the Executive Stock.

               (iii) Executive is able to bear the economic risk of her
     investment in the Executive Stock for an indefinite period of time because
     the Executive Stock has not been registered under the Securities Act and,
     therefore, cannot be sold unless subsequently registered under the
     Securities Act or an exemption from such registration is available.

               (iv)  Executive has had an opportunity to ask questions and
     receive answers concerning the terms and conditions of the offering of
     Executive Stock and has had full access to such other information
     concerning the Company as he has requested.

               (v)   This Agreement constitutes the legal, valid and binding
     obligation of Executive, enforceable in accordance with its terms, and the
     execution, delivery and performance of this Agreement by Executive does not
     and will not conflict with, violate or cause a breach of any agreement,
     contract or instrument to which Executive is a party or any judgment, order
     or decree to which Executive is subject.

               (vi)  Executive 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 Executive is a party to or by which
     Executive is bound.

               (vii) Executive is a resident of the State of Massachusetts.

          (e)  As an inducement to the Company to issue the Executive Stock to
Executive, and as a condition thereto, Executive acknowledges and agrees that
neither the issuance of the Executive Stock to Executive nor any provision
contained herein shall entitle Executive to remain

                                      -2-

in the employment of the Company or any of its Subsidiaries or affect the right
of the Company to terminate Executive's employment at any time for any reason,
subject, however, to the terms of this Agreement.

          (f)  Concurrently with the execution of this Agreement, (i) Executive
shall execute in blank ten stock transfer powers in the form of Exhibit C
                                                                ---------
attached hereto (the "Stock Powers") with respect to the Executive 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 Executive
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
Executive's spouse shall execute the consent in the form of Exhibit D attached
                                                            ---------
hereto.

          2.   Vesting of Executive Stock.
               --------------------------

          (a)  All of the shares of Executive Stock acquired hereunder shall be
subject to vesting in the manner specified in this Section 2. Except as
otherwise provided in Sections 2(b) and 2(c) below, the Executive Stock will
become vested in accordance with the following schedule (the "Vesting
                                                              -------
Schedule"), if as of each such date Executive is still employed by the Company
- --------
or any of its Subsidiaries:


                   Date              Cumulative Percentage of
                   ----              Executive Stock to be Vested
                                     ----------------------------

             March 31, 2000                   20%
             March 31, 2001                   40%

             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 Executive is still employed by the Company or any
of its Subsidiaries, the Executive 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

                                      -3-
<PAGE>

     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

     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

     December 31 and March 31 so that the Executive Stock will be 100% vested on
     March 31, 2004.

   (c)    Upon the occurrence of a Transaction, all shares of Executive 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 Executive Stock which have become vested
          are referred to herein as "Vested Shares" and all other shares of
                                     -------------
          Executive Stock are referred to herein as "Unvested Shares."
                                                     ---------------

               3.   Repurchase Option.
                    -----------------

               (a)  In the event (i) Executive ceases to be employed by the
Company and its Subsidiaries for any reason (the "Separation") or (ii) Executive
                                                  ----------
fails to make any principal or interest payment under the Executive Note after
such payment becomes due and after giving effect to any applicable grace period
(a "Triggering Event"), the Executive Stock (whether held by Executive or one or
    ----------------
more of Executive'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 Executive Stock will be Executive's Original Cost for
such share and (ii) the purchase price for each Vested Share of Executive Stock
will be the Fair Market Value for such share as at the date of the Separation;
provided, however, that if Executive's employment is terminated with Cause, the
- --------  -------
purchase price for each Vested Share of Executive Stock will be Executive'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 Executive Stock (whether a Vested Share or
Unvested Share) will be Executive'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 Executive 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

                                      -4-
<PAGE>

to the extent possible from the shares of Executive Stock held by Executive at
the time of delivery of the Repurchase Notice. If the number of shares of
Executive Stock then held by Executive is less than the total number of shares
of Executive Stock which the Company has elected to purchase, the Company shall
purchase the remaining shares elected to be purchased from the other holder(s)
of Executive Stock under this Agreement, pro rata according to the number of
shares of Executive Stock held by such other holder(s) at the time of delivery
of such Repurchase Notice (determined as nearly as practicable to the nearest
share). The number of Unvested Shares and Vested Shares to be repurchased
hereunder will be allocated among Executive and the other holders of Executive
Stock (if any) pro rata according to the number of shares of Executive Stock to
be purchased from such person.

          (d)  If for any reason the Company does not elect to purchase all of
the Executive Stock pursuant to the Repurchase Option, all other 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 Executive 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
Executive Stock as to the 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 Executive 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 Executive Stock to be purchased by each of them.

          (e)  The closing of the purchase of the Executive Stock pursuant to
the Repurchase Option shall take place on the date designated by the Company in
the Repurchase Notice or Supplemental Repurchase Notice, which date shall not be
more than one month nor less than five days after the delivery of the later of
either such notice to be delivered. The Company will pay for the Executive Stock
to be repurchased by it pursuant to the Repurchase Option with (i) a check or

                                      -5-
<PAGE>

wire transfer of funds for (A) any shares of Executive Stock to be repurchased
at Executive's Original Cost and (B) in the case of Executive Stock to be
repurchased at Fair Market Value, that portion of such Executive Stock which is
equal to the Executive's Original Cost, and (ii) in the case of Executive Stock
to be repurchased at Fair Market Value, a subordinate note or notes for that
portion of such Executive Stock which exceeds the Executive'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 Executive to the Company.
Each Senior Manager and each Investor will pay for the Executive 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 Executive Stock.

          (f)  Notwithstanding anything to the contrary contained in this
Agreement, all repurchases of Executive Stock by the Company shall be subject to
applicable restrictions contained in the Delaware General Corporation Law and in
the Company's and its Subsidiaries' debt and equity financing agreements.  If
any such restrictions prohibit the repurchase of Executive Stock hereunder which
the Company is otherwise entitled or required to make, the Company may make such
repurchases as soon as it is permitted to do so under such restrictions.

          (g)  Notwithstanding anything to the contrary contained in this
Agreement, if the Fair Market Value of a share of Executive Stock is finally
determined to be an amount at least 10% greater than the per share repurchase
price for such share of Executive Stock in the Repurchase Notice or in the
Supplemental Repurchase Notice, each of the Company and the Investors shall have
the right to revoke its exercise of the Repurchase Option for all or any portion
of the Executive Stock elected to be repurchased by it by delivering notice of
such revocation in writing to the holders of Executive Stock during the thirty-
day period beginning on the date that the Company and/or the Investors are given
written notice that the Fair Market Value of a share of Executive Stock was
finally determined to be an amount at least 10% greater than the per share
repurchase price for Executive 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 Executive Stock.
               -------------------------------------------

          (a)  Transfer of Executive Stock.  The holder of Executive Stock shall
               ---------------------------
not Transfer any interest in any shares of Executive Stock, except pursuant to
(i) the provisions of Section 3  hereof, (ii) the provisions of Section 3 of the
Stockholders Agreement (a "Participating Sale"), (iii) an Approved Sale (as
                           ------------------
defined in Section 5 of the Stockholders Agreement), or (iv) the

                                      -6-
<PAGE>

provisions of Section 4(b) below.

          (b)  Certain Permitted Transfers.  The restrictions in this Section 4
               ---------------------------
will not apply with respect to any Transfer of Executive Stock if made (i)
pursuant to applicable laws of descent and distribution or to such Person's
legal guardian in the case of any mental incapacity or among such Person's
Family Group, or (ii) at a time when (A) the Common Stock of the Company has
been trading for at least 45 consecutive days (including the day immediately
preceding such Transfer) at a price that exceeds the initial Public Offering
price by at least 20% and (B) the Common Stock bid and asked price on the day of
such Transfer was at least 20% greater than the initial Public Offering price,
but in the case of this clause (ii) only an amount of shares per calendar year
up to the lesser of (x) the number of Vested Shares owned by Executive at the
time of such Transfer and (y) 10% of the total number of shares of Common Stock
owned by Executive at the time of the Company's initial Public Offering, or
(iii) at such time as the Investors sell shares of Common Stock in a Public
Sale, but in the case of this clause (iii) only an amount of shares (the
"Transfer Amount") equal to the lesser of (C) the number of Vested Shares of
 ---------------
Common Stock owned by Executive at the time of such Transfer and (D) the number
of shares of Common Stock owned by Executive multiplied by a fraction (the
"Transfer Fraction"), the numerator of which is the number of shares of Common
 -----------------
Stock sold by the Investors in such Public Sale and the denominator of which is
the total number of shares of Common Stock held by the Investors prior to the
Public Sale; provided that, if at the time of a Public Sale of shares by the
             -------- ----
Investors, Executive chooses not to Transfer the Transfer Amount, Executive
shall retain the right to Transfer an amount of Executive Stock at a future date
equal to the lesser of (x) the number of Vested Shares owned by Executive at
such future date and (y) the number of shares of Executive Stock owned by
Executive at such future date multiplied by the Transfer Fraction; provided
                                                                   --------
further, that at any particular point in time during any given calendar year the
- -------
number of shares of Common Stock which the Executive has a right to Transfer
pursuant to clause (ii) above shall be reduced by the number of shares of Common
Stock which the Executive has Transferred in such calendar year pursuant to
clause (iii) above and the number of shares of Common Stock which the Executive
has a right to Transfer pursuant to clause (iii) above shall be reduced by the
number of shares of Common Stock which the Executive has Transferred in such
calendar year pursuant to clause (ii) above.  Notwithstanding anything in this
Section 4 to the contrary, the restrictions contained in this Section 4 will
continue to be applicable to the Executive Stock after any Transfer of the type
referred to in clause (i) and the transferees of such Executive Stock will agree
in writing to be bound by the provisions of this Agreement.  Any transferee of
Executive Stock pursuant to a transfer in accordance with the provisions of this
Section 4(b)(i) is herein referred to as a "Permitted Transferee."  Upon the
                                            --------------------
transfer of Executive Stock pursuant to this Section 4(b), the transferring
Executive Stockholder will deliver a written notice (a "Transfer Notice") to the
                                                        ---------------
Company.  In the case of a Transfer pursuant to clause (i) hereof, the Transfer
Notice will disclose in reasonable detail the identity of the Permitted
Transferee(s).  In addition, following the completion of an initial Public
Offering, Executive, in her sole discretion, may pledge up to $2 million worth
of Vested Shares as collateral for a loan so long as the pledgee of such stock
and the Executive enter into a pledge agreement in form and substance reasonably
satisfactory to the Board of Directors of the Company (the "Board"), pursuant to
which pledgee, among other things, agrees that pledgee may only sell such stock
in a Public Sale.

                                      -7-
<PAGE>

          (c)  Termination of Restrictions.  The restrictions set forth in this
               ---------------------------
Section 4 will continue with respect to each share of Executive Stock until the
earlier of (i) the date on which such share of Executive Stock has been
transferred in a Public Sale permitted by this Section 4, or (ii) the
consummation of an Approved Sale.

          5.   Additional Restrictions on Transfer of Executive Stock.
               ------------------------------------------------------

          (a)  Legend.  The certificates representing the Executive Stock will
               ------
bear a legend in substantially the following form:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ORIGINALLY
     ISSUED AS OF AUGUST ___, 1999, HAVE NOT BEEN REGISTERED UNDER
     THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT
                                                  ---
     BE SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE
     REGISTRATION STATEMENT UNDER THE ACT OR AN EXEMPTION FROM
     REGISTRATION THEREUNDER. THE SECURITIES REPRESENTED BY THIS
     CERTIFICATE ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON
     TRANSFER, CERTAIN REPURCHASE OPTIONS AND CERTAIN OTHER
     AGREEMENTS SET FORTH IN A SENIOR MANAGEMENT AGREEMENT BETWEEN
     THE COMPANY AND AN EXECUTIVE OF THE COMPANY DATED AS OF AUGUST
     ___, 1999. A COPY OF SUCH AGREEMENT MAY BE OBTAINED BY THE
     HOLDER HEREOF AT THE COMPANY'S PRINCIPAL PLACE OF BUSINESS
     WITHOUT CHARGE."

          (b)  Opinion of Counsel.  No holder of Executive Stock may sell,
               ------------------
transfer or dispose of any Executive Stock (except pursuant to an effective
registration statement under the Securities Act) without first delivering to the
Company an 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 Executive Stock delivers to the
Company an opinion of counsel that no subsequent transfer of such Executive
Stock shall require registration under the Securities Act, the Company shall
promptly upon such contemplated transfer deliver new certificates for such
Executive 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 Executive 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.

     previously deferred by the Executive (together with any accrued interest or
     earnings thereon) and any accrued vacation pay, in each case to the extent
     not previously paid (the obligations set forth in clauses (A) and (B) are

               (ii)  the Company shall pay each month to the Executive,
     beginning on the date of the first normal executive payroll of the Company
     that occurs more than 30 days after such termination or resignation, an
     amount equal to one-twelfth (1/12) of the Executive's Annual Base Salary as
     of the date immediately before such termination or resignation; provided
                                                                     --------
     however, that such payments shall immediately cease upon the earliest to
     --------
     occur of (x) the Executive's death and (y) the six month anniversary of
     such termination or resignation. Notwithstanding anything in this Section
     6(d) to the contrary, in the event that the Executive becomes employed with
     another employer, then the payments to be made by the Company pursuant to
     this Section 6(d)(ii) shall be reduced (on a dollar for dollar basis) in an
     amount equal to the cash compensation received by Executive from such
     employer; and

               (iii) the Company shall continue to provide medical insurance
     benefits to the Executive and to the Executive's family at least equal to
     those medical insurance benefits that would have been provided to them in
     the absence of such termination or resignation; provided however, that such
                                                     -------- -------
     payments shall immediately cease upon the earliest to occur of (x) the
     Executive's death and (y) the six month anniversary of such termination or
     resignation. Notwithstanding anything in this Section 6(d) to the contrary,
     in the event that the Executive becomes employed with another employer and
     is eligible for medical insurance benefits under another employer-provided
     plan, then the medical insurance benefits to be provided by the Company
     pursuant to this Section 6(d)(iii) shall be reduced to the extent that the
     Executive and his/her family is eligible to receive medical insurance
     benefits under such other employer-provided plan.

          (e)  Other Separations. In the event of a Separation other than a
               -----------------
termination by the Company without cause or a resignation by the Executive for
Good Reason, the Company shall pay to the Executive (or his/her estate, if
applicable), in a lump sum in cash within 15 days after such Separation, an
amount equal to any Accrued Obligations.

          7.   Confidential Information. Executive acknowledges that the
               ------------------------
information, observations and data obtained by him during the course of his/her
performance under this Agreement concerning the business and affairs of the
Company and its affiliates are the property of the Company, including
information concerning acquisition opportunities in or reasonably related to the
Company's business or industry of which Executive becomes aware during the
Employment Period. Therefore, Executive agrees that he will not disclose to any
unauthorized person or use for his/her own account any of such information,
observations or data without the Company's written consent, unless and to the
extent that the aforementioned matters become generally known to and available
for use by the public other than as a result of Executive's acts or omissions to
act. Executive agrees to deliver to the Company at a Separation, or at any other
time the Company may request in writing, all memoranda, notes, plans, records,
reports and other documents (and copies thereof) relating to the business of the
Company and its affiliates (including, without limitation, all acquisition
prospects, lists and contact information) which he may then possess or have
under his/her control.

<PAGE>

          8.   Noncompetition and Nonsolicitation. Executive acknowledges
               ----------------------------------
that in the course of his/her employment with the Company he will become
familiar with the Company's and its Subsidiaries' trade secrets and with other
confidential information concerning the Company and such Subsidiaries and that
his/her services will be of special, unique and extraordinary value to the
Company. Therefore, Executive agrees that:

          (a)  Noncompetition.  During the Employment Period and for a period of
               --------------
one year thereafter (the "Noncompete Period"), Executive shall not, within the
                          -----------------
United States, directly or indirectly own, manage, control, participate in,
consult with, render services for, or in any manner engage in any business
competing with the businesses of the Company or its Subsidiaries or any business
in which the Company or any of its Subsidiaries has requested and received
information relating to the acquisition of such business by the Company and the
Subsidiaries prior to the Separation; provided that passive ownership of less
                                      --------
than 5% of the outstanding stock of any publicly-traded corporation shall not,
in and of itself, be deemed to violate this Section 8(a); provided further that
                                                          --------
if the Executive's Employment with the Company is terminated by the Company
without Cause or the Executive resigns for Good Reason within a twenty four
month period following a Sale of the Company, the one year period referenced
above shall be shortened to a six month period.

          (b)  Nonsolicitation.  During the Noncompete Period, Executive shall
               ---------------
not directly or indirectly through another entity (i) induce or attempt to
induce any employee of the Company or its Subsidiaries to leave the employ of
the Company or such Subsidiary, or in any way interfere with the relationship
between the Company and any Subsidiary and any employee thereof, (ii) hire any
person who was an employee of the Company and any Subsidiary within 180 days
prior to the time such employee was hired by the Executive, (iii) induce or
attempt to induce any customer, supplier, licensee or other business relation of
the Company and any Subsidiary to cease doing business with the Company or such
Subsidiary or in any way interfere with the relationship between any such
customer, supplier, licensee or business relation and the Company and any
Subsidiary or (iv) directly or indirectly acquire or attempt to acquire an
interest in any business relating to the business of the Company and any
Subsidiary and with which the Company and any Subsidiary has entertained
discussions or has requested and received information relating to the
acquisition of such business by the Company and any Subsidiary in the two-year
period immediately preceding a Separation.

          (c)  Enforcement. If, at the time of enforcement of Section 7 or this
               -----------
Section 8, a court holds that the restrictions stated herein are unreasonable
under circumstances then existing, the parties hereto agree that the maximum
duration, scope or geographical area reasonable under such circumstances shall
be substituted for the stated period, scope or area and that the court shall be
allowed to revise the restrictions contained herein to cover the maximum
duration, scope and area permitted by law. Because Executive's services are
unique and because Executive has access to confidential information, the parties
hereto agree that money damages would be an inadequate remedy for any breach of
this Agreement. Therefore, in the event a breach or threatened breach of this
Agreement, the Company or its successors or assigns may, in addition to other
rights and

                                      -11-
<PAGE>

remedies existing in their favor, apply to any court of competent jurisdiction
for specific performance and/or injunctive or other relief in order to enforce,
or prevent any violations of, the provisions hereof (without posting a bond or
other security).

          (d)  Additional Acknowledgments.  Executive acknowledges that the
               --------------------------
provisions of this Section 8 are in consideration of: (i) employment with the
Company, (ii) the issuance of the Executive Stock and (iii) additional good and
valuable consideration as set forth in this Agreement. In addition, Executive
agrees and acknowledges that the restriction contained in Section 7 and this
Section 8 do not preclude Executive from earning a livelihood, nor do they
unreasonably impose limitations on Executive's ability to earn a living. In
addition, Executive agrees and acknowledges that the potential harm to the
Company of the non-enforcement of Section 7 and this Section 8 outweighs any
potential harm to Executive of its enforcement by injunction or otherwise.
Executive acknowledges that he has carefully read this Agreement and has given
careful consideration to the restraints imposed upon Executive by this
Agreement, and is in full accord as to their necessity for the reasonable and
proper protection of confidential and proprietary information of the Company now
existing or to be developed in the future. Executive expressly acknowledges and
agrees that each and every restraint imposed by this Agreement is reasonable
with respect to subject matter, time period and geographical area.

<PAGE>

other than Executive (except for the Company and the Investors and except for
transferees in a Public Sale), and except as otherwise provided herein, each

          "Fair Market Value" of each share of Executive Stock means the average
           -----------------
of the closing prices of the sales of such Executive Stock on all securities
exchanges on which such Executive Stock may at the time be listed, or, if there
have been no sales on any such exchange on any day, the average of the highest
bid and lowest asked prices on all such exchanges at the end of such day, or, if
on any day such Executive Stock is not so listed, the average of the
representative bid and asked prices quoted in the NASDAQ System as of 4:00 P.M.,

such case averaged over a period of 21 days consisting of the day as of which
the Fair Market Value is being determined and the 20 consecutive business days
prior to such day. If at any time such Executive Stock is not listed on any

the delivery of the Repurchase Notice (or if no Repurchase Notice is delivered,

Fair Market Value shall be determined by an appraiser jointly selected by the
Board and the Executive, which appraiser shall submit to the Board and the
Executive a report within 30 days of its engagement setting forth such
determination. If the parties are unable to agree on an appraiser within 45 days
after delivery of the Repurchase Notice or the Supplemental Repurchase Notice,
within seven days, each party shall submit the names of four nationally
recognized investment banking firms, and each party shall be entitled to strike
two names from the other party's list of firms, and the appraiser shall be
selected by lot from the remaining four investment banking firms. The expenses
of such appraiser shall be borne by the party whose Fair Market Value
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.

          (b)  Transfers in Violation of Agreement.  Any Transfer or attempted
               -----------------------------------
Transfer of any Executive Stock in violation of any provision of this Agreement
shall be void, and the Company shall not record such Transfer on its books or
treat any purported transferee of such Executive Stock as the owner of such

          (c)  Severability. Whenever possible, each provision of this Agreement
               ------------
will be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Agreement is held to be invalid, illegal or
unenforceable in any respect under any applicable law

                                      -16-
<PAGE>

or rule in any jurisdiction, such invalidity, illegality or unenforceability
will not affect any other provision or any other jurisdiction, but this
Agreement will be reformed, construed and enforced in such jurisdiction as if
such invalid, illegal or unenforceable provision had never been contained
herein.

          (d)  Complete Agreement.  This Agreement, those documents expressly
               ------------------
referred to herein and other documents of even date herewith embody the complete

together constitute one and the same agreement.

          (f)  Successors and Assigns. Except as otherwise provided herein, this
               ----------------------
Agreement shall bind and inure to the benefit of and be enforceable by

assigns (including subsequent holders of Executive Stock); provided that the
rights and obligations of Executive under this Agreement shall not be assignable
except in connection with a permitted transfer of Executive Stock hereunder.

          (g)  Choice of Law.  The laws of Delaware shall govern all issues
               -------------

questions concerning the construction, validity and interpretation of this
Agreement, without giving effect to any choice of law or other conflict of law
provision or rule (whether of the State of Delaware or any other jurisdiction)
that would cause the application of the laws of any jurisdiction other than the
State of Delaware.

          (h)  Remedies.  Each of the parties to this Agreement (including the
               --------
Investors) will be entitled to enforce its rights under this Agreement
specifically, to recover damages and costs (including attorney's fees) caused by
any breach of any provision of this Agreement and to exercise all other rights

damages may not be an adequate remedy for any breach of the provisions of this
Agreement and that any party may in its sole discretion apply to any court of
law or equity of competent jurisdiction (without posting any bond or deposit)
for specific performance and/or other injunctive relief in order to enforce or
prevent any violations of the provisions of this Agreement.

          (i)  Amendment and Waiver.  The provisions of this Agreement may be

supply any information, and to execute and deliver any applications or other
instruments in writing as may be reasonably necessary to obtain and constitute

that her life is not insurable at rates now prevailing for healthy persons of
his/her age.

          (k)  Business Days.  If any time period for giving notice or taking
               -------------
action hereunder expires on a day which is a Saturday, Sunday or holiday in the

shall be automatically extended to the business day immediately following such

               ----------------------------------------------------------------
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 generally accepted
accounting principles, consistently applied, except that if because of a change
in generally accepted accounting principles the Company would have to alter a
previously utilized accounting method or policy in order to remain in compliance
with generally accepted accounting principles, 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.

          (o)  Deemed Transfer of Executive Stock.  If the Company (and/or the
               ----------------------------------
Investors and/or any other Person acquiring securities) shall make available, at
the time and place and in the amount and form provided in this Agreement, the
consideration for the Executive Stock to be repurchased in accordance with the
provisions of this Agreement, then from and after such time, the person from
whom such shares are to be repurchased shall no longer have any rights as a
holder of such shares (other than the right to receive payment of such
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

therefor have been delivered as required by this Agreement.

          (p)  No Pledge or Security Interest.  The purpose of the Company's
               ------------------------------
retention of the Executive's stock certificates and executed stock powers is
solely to facilitate the repurchase provisions set forth in Section 3 herein and
does not constitute a pledge by the Executive of, or the granting of a security
interest in, the underlying stock.

          (q)  Rights Granted to GTCR and its Affiliates.  Any rights granted to
               -----------------------------------------
GTCR and its Affiliates hereunder may also be exercised (in whole or in part) by

     days.

          (b)  Consequences of Events of Default.
               ---------------------------------

          If an Event of Default of the type described in subparagraph 3(a)(ii)

portion of the outstanding principal amount of the Note (together with all
accrued interest thereon and all other amounts due in
<PAGE>

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.

          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.
               105 South Street
               Boston, MA 02111

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
<PAGE>

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
          -------------
law, not the laws of conflicts, of the State of Delaware.

enforceable by, 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 EXECUTIVE STOCK

Company will sell, 105,000 shares of Common Stock at a price of $.50 per share.
The Company will deliver to Executive the certificates representing such
Executive Stock, and Executive will deliver to the Company a cashier's or
certified check or wire transfer of funds in the aggregate amount of $4,606.88
and a promissory note in the form of Exhibit A attached hereto in an aggregate
                                     ---------
principal amount of $47,893.13 (the "Executive Note").
                                     --------------

          (b) Within 30 days after the date hereof, Executive will make an

Offering, all certificates evidencing shares of Executive Stock shall be held by

Executive and the other holder(s) of Executive Stock. Upon the occurrence of a
Sale of the Company or a Public Offering, the Company will return the
certificates for the Executive Stock to the record holders thereof.

          (d) In connection with the purchase and sale of the Executive Stock,
Executive represents and warrants to the Company that:

               (i)    The Executive Stock to be acquired by Executive pursuant
     to this Agreement will be acquired for Executive's own account and not with
     a view to, or intention of, distribution thereof in violation of the
     Securities Act, or any applicable state securities laws, and the Executive
     Stock will not be disposed of in contravention of the Securities Act or any
     applicable state securities laws.

               (ii)   Executive is an executive officer of the Company, is
     sophisticated in financial matters and is able to evaluate the risks and
     benefits of the investment in the Executive Stock.

               (iii)  Executive is able to bear the economic risk of her
     investment in the Executive Stock for an indefinite period of time because
     the Executive Stock has not been registered under the Securities Act and,
     therefore, cannot be sold unless subsequently registered under the
     Securities Act or an exemption from such registration is available.

               (iv)   Executive has had an opportunity to ask questions and
     receive answers concerning the terms and conditions of the offering of
     Executive Stock and has had full access to such other information
     concerning the Company as he has requested.

               (v)    This Agreement constitutes the legal, valid and binding
     obligation of Executive, enforceable in accordance with its terms, and the
     execution, delivery and performance of this Agreement by Executive does not
     and will not conflict with, violate or cause a breach of any agreement,
     contract or instrument to which Executive is a party or any judgment, order
     or decree to which Executive is subject.

               (vi)   Executive 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 Executive is a party to or by which
     Executive is bound.

               (vii)  Executive is a resident of the State of Massachusetts.

          (e) As an inducement to the Company to issue the Executive Stock to
Executive, and as a condition thereto, Executive acknowledges and agrees that
neither the issuance of the Executive Stock to Executive nor any provision
contained herein shall entitle Executive to remain in the employment of the
Company or any of its Subsidiaries or affect the right of the Company to
terminate Executive's employment at any time for any reason, subject, however,
to the terms of this Agreement.

               (b)  In the event of a Separation, (i) the purchase price for
each Unvested Share of Executive Stock will be Executive's Original Cost for
such share and (ii) the purchase price for each Vested Share of Executive Stock
will be the Fair Market Value for such share as at the date of the Separation;
provided, however, that if Executive's employment is terminated with Cause, the
- --------  -------
purchase price for each Vested Share of Executive Stock will be Executive'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 Executive Stock (whether a Vested Share or
Unvested Share) will be Executive'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 Executive 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 Executive Stock held by Executive at the time of delivery of the
Repurchase Notice.  If the number of shares of Executive Stock then held by
Executive is less than the total number of shares of Executive Stock which the
Company has elected to purchase, the Company shall purchase the remaining shares
elected to be purchased from the other holder(s) of Executive Stock under this
Agreement, pro rata according to the number of shares of Executive Stock held by
such other holder(s) at the time of delivery of such Repurchase Notice
(determined as

                                      -4-
<PAGE>

nearly as practicable to the nearest share). The number of Unvested Shares and
Vested Shares to be repurchased hereunder will be allocated among Executive and
the other holders of Executive Stock (if any) pro rata according to the number
of shares of Executive Stock to be purchased from such person.

          (d) If for any reason the Company does not elect to purchase all of
the Executive Stock pursuant to the Repurchase Option, all other 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 Executive 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
Executive Stock as to the 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 Executive 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 Executive Stock to be purchased by each of them.

          (e) The closing of the purchase of the Executive Stock pursuant to the
Repurchase Option shall take place on the date designated by the Company in the
Repurchase Notice or Supplemental Repurchase Notice, which date shall not be
more than one month nor less than five days after the delivery of the later of
either such notice to be delivered.  The Company will pay for the Executive
Stock to be repurchased by it pursuant to the Repurchase Option with (i) a check
or wire transfer of funds for (A) any shares of Executive Stock to be
repurchased at Executive's Original Cost and (B) in the case of Executive Stock
to be repurchased at Fair Market Value, that portion of such Executive Stock
which is equal to the Executive's Original Cost, and (ii) in the case of
Executive Stock to be repurchased at Fair Market Value, a subordinate note or
notes for that  portion of such Executive Stock which exceeds the Executive'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

                                      -5-
<PAGE>

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 Executive to the Company. Each Senior Manager and each
Investor will pay for the Executive 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 Executive Stock.

          (f) Notwithstanding anything to the contrary contained in this
Agreement, all repurchases of Executive Stock by the Company shall be subject to
applicable restrictions contained in the Delaware General Corporation Law and in
the Company's and its Subsidiaries' debt and equity financing agreements.  If
any such restrictions prohibit the repurchase of Executive Stock hereunder which
the Company is otherwise entitled or required to make, the Company may make such
repurchases as soon as it is permitted to do so under such restrictions.

          (g) Notwithstanding anything to the contrary contained in this
Agreement, if the Fair Market Value of a share of Executive Stock is finally
determined to be an amount at least 10% greater than the per share repurchase
price for such share of Executive Stock in the Repurchase Notice or in the
Supplemental Repurchase Notice, each of the Company and the Investors shall have
the right to revoke its exercise of the Repurchase Option for all or any portion
of the Executive Stock elected to be repurchased by it by delivering notice of
such revocation in writing to the holders of Executive Stock during the thirty-
day period beginning on the date that the Company and/or the Investors are given
written notice that the Fair Market Value of a share of Executive Stock was
finally determined to be an amount at least 10% greater than the per share
repurchase price for Executive 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 Executive Stock.
              -------------------------------------------

          (a) Transfer of Executive Stock.  The holder of Executive Stock shall
              ---------------------------
not Transfer any interest in any shares of Executive Stock, except pursuant to
(i) the provisions of Section 3  hereof, (ii) the provisions of Section 3 of the
Stockholders Agreement (a "Participating Sale"), (iii) an Approved Sale (as
                           ------------------
defined in Section 5 of the Stockholders Agreement), or (iv) the provisions of
Section 4(b) below.

          (b) Certain Permitted Transfers.  The restrictions in this Section 4
              ---------------------------
will not apply with respect to any Transfer of Executive Stock if made (i)
pursuant to applicable laws of descent and distribution or to such Person's
legal guardian in the case of any mental incapacity or among such Person's
Family Group, or (ii) at a time when (A) the Common Stock of the Company has
been trading for at least 45 consecutive days (including the day immediately
preceding such Transfer) at a price that exceeds the initial Public Offering
price by at least 20% and (B) the Common Stock bid and asked price on the day of
such Transfer was at least 20% greater than the initial Public Offering price,
but in the case of this clause (ii) only an amount of shares per calender year
up to the lesser of (x) the number of Vested Shares owned by Executive at the
time of such Transfer and (y) 10% of the

                                      -6-
<PAGE>

total number of shares of Common Stock owned by Executive at the time of the
Company's initial Public Offering, or (iii) at such time as the Investors sell
shares of Common Stock in a Public Sale, but in the case of this clause (iii)
only an amount of shares (the "Transfer Amount") equal to the lesser of (C) the
                               ---------------
number of Vested Shares of Common Stock owned by Executive at the time of such
Transfer and (D) the number of shares of Common Stock owned by Executive
multiplied by a fraction (the "Transfer Fraction"), the numerator of which is
                               -----------------
the number of shares of Common Stock sold by the Investors in such Public Sale
and the denominator of which is the total number of shares of Common Stock held
by the Investors prior to the Public Sale; provided that, if at the time of a
                                           -------- ----
Public Sale of shares by the Investors, Executive chooses not to Transfer the
Transfer Amount, Executive shall retain the right to Transfer an amount of
Executive Stock at a future date equal to the lesser of (x) the number of Vested
Shares owned by Executive at such future date and (y) the number of shares of
Executive Stock owned by Executive at such future date multiplied by the
Transfer Fraction; provided further, that at any particular point in time during
                   -------- -------
any given calendar year the number of shares of Common Stock which the Executive
has a right to Transfer pursuant to clause (ii) above shall be reduced by the
number of shares of Common Stock which the Executive has Transferred in such
calendar year pursuant to clause (iii) above and the number of shares of Common
Stock which the Executive has a right to Transfer pursuant to clause (iii) above
shall be reduced by the number of shares of Common Stock which the Executive has
Transferred in such calendar year pursuant to clause (ii) above. Notwithstanding
anything in this Section 4 to the contrary, the restrictions contained in this
Section 4 will continue to be applicable to the Executive Stock after any
Transfer of the type referred to in clause (i) and the transferees of such
Executive Stock will agree in writing to be bound by the provisions of this
Agreement. Any transferee of Executive Stock pursuant to a transfer in
accordance with the provisions of this Section 4(b)(i) is herein referred to as
a "Permitted Transferee." Upon the transfer of Executive Stock pursuant to this
   --------------------
Section 4(b), the transferring Executive Stockholder will deliver a written
notice (a "Transfer Notice") to the Company. In the case of a Transfer pursuant
           ---------------
to clause (i) hereof, the Transfer Notice will disclose in reasonable detail the
identity of the Permitted Transferee(s). In addition, following the completion
of an initial Public Offering, Executive, in her sole discretion, may pledge up
to $2 million worth of Vested Shares as collateral for a loan so long as the
pledgee of such stock and the Executive enter into a pledge agreement in form
and substance reasonably satisfactory to the Board of Directors of the Company
(the "Board"), pursuant to which pledgee, among other things, agrees that
pledgee may only sell such stock in a Public Sale.

          (c) Termination of Restrictions.  The restrictions set forth in this
              ---------------------------
Section 4 will continue with respect to each share of Executive Stock until the
earlier of (i) the date on which such share of Executive Stock has been
transferred in a Public Sale permitted by this Section 4, or (ii) the
consummation of an Approved Sale.

          5.  Additional Restrictions on Transfer of Executive Stock.
              ------------------------------------------------------

          (a) Legend.  The certificates representing the Executive Stock will
              ------
bear a legend in substantially the following form:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ORIGINALLY ISSUED AS
     OF MAY 21, 1999, HAVE NOT BEEN REGISTERED

                                      -7-
<PAGE>

     UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT BE
                                                        ---
     SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
     UNDER THE ACT OR AN EXEMPTION FROM REGISTRATION THEREUNDER. THE SECURITIES
     REPRESENTED BY THIS CERTIFICATE ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS
     ON TRANSFER, CERTAIN REPURCHASE OPTIONS AND CERTAIN OTHER AGREEMENTS SET
     FORTH IN A SENIOR MANAGEMENT AGREEMENT BETWEEN THE COMPANY AND AN EXECUTIVE
     OF THE COMPANY DATED AS OF MAY 21, 1999. A COPY OF SUCH AGREEMENT MAY BE
     OBTAINED BY THE HOLDER HEREOF AT THE COMPANY'S PRINCIPAL PLACE OF BUSINESS
     WITHOUT CHARGE."

          (b) Opinion of Counsel.  No holder of Executive Stock may sell,
              ------------------
transfer or dispose of any Executive Stock (except pursuant to an effective
registration statement under the Securities Act) without first delivering to the
Company an 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 Executive Stock delivers to the
Company an opinion of counsel that no subsequent transfer of such Executive
Stock shall require registration under the Securities Act, the Company shall
promptly upon such contemplated transfer deliver new certificates for such
Executive 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 Executive 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.

                       PROVISIONS RELATING TO EMPLOYMENT

          6.  Employment.  The Company agrees to employ Executive and Executive

Executive's  resignation, disability (as determined by the President in his good
faith judgment) or death or until the President decides to terminate Executive's
employment.

          (d) Separation Without Cause; Resignation for Good Reason.  In the
              -----------------------------------------------------
event that (i) the Company terminates the Executive's employment without Cause
or (ii) the Executive resigns from her position with the Company for Good
Reason, then the Executive shall be entitled to the following:

     case to the extent not previously paid (the obligations set forth in
     clauses (A) and (B) are collectively referred to herein as the "Accrued
                                                                     -------
     Obligations");
     -----------

               (ii)   the Company shall pay each month to the Executive,
     beginning on the date of the first normal executive payroll of the Company
     that occurs more than 30 days after such termination or resignation, an
     amount equal to one-twelfth (1/12) of the Executive's Annual Base Salary as
     of the date immediately before such termination or resignation; provided
                                                                     --------
     however, that such payments shall immediately cease upon the earliest to
     -------
     occur of (x) the Executive's death and (y) the six month anniversary of
     such termination or resignation. Notwithstanding anything in this Section
     6(d) to the contrary, in the event that the Executive becomes employed with
     another employer, then the payments to be made by the Company pursuant to
     this Section 6(d)(ii) shall be reduced (on a dollar for dollar basis) in an
     amount equal to the cash compensation received by Executive from such
     employer; and

               (iii)  the Company shall continue to provide medical insurance
     benefits to the Executive and to the Executive's family at least equal to
     those medical insurance benefits that would have been provided to them in
     the absence of such termination or resignation; provided however, that such
                                                     -------- -------
     payments shall immediately cease upon the earliest to occur of (x) the
     Executive's death and (y) the six month anniversary of such termination or
     resignation.  Notwithstanding anything in this Section 6(d) to the
     contrary, in the event that the Executive becomes employed with another
     employer and is eligible for medical insurance benefits under another
     employer-provided plan, then the medical insurance

                                      -9-
<PAGE>

     benefits to be provided by the Company pursuant to this Section 6(d)(iii)
     shall be reduced to the extent that the Executive and her family is
     eligible to receive medical insurance benefits under such other employer-
     provided plan.

          (e) Other Separations.  In the event of a Separation other than a
              -----------------
termination by the Company without cause or a resignation by the Executive for
Good Reason, the Company shall pay to the Executive (or her estate, if
applicable), in a lump sum in cash within 15 days after such Separation, an
amount equal to any Accrued Obligations.

          7.  Confidential Information. Executive acknowledges that the
              ------------------------
information, observations and data obtained by him during the course of her
performance under this Agreement concerning the business and affairs of the
Company and its affiliates are the property of the Company, including
information concerning acquisition opportunities in or reasonably related to the
Company's business or industry of which Executive becomes aware during the
Employment Period. Therefore, Executive agrees that he will not disclose to any
unauthorized person or use for her own account any of such information,
observations or data without the Company's written consent, unless and to the
extent that the aforementioned matters become generally known to and available
for use by the public other than as a result of Executive's acts or omissions to
act. Executive agrees to deliver to the Company at a Separation, or at any other
time the Company may request in writing, all memoranda, notes, plans, records,
reports and other documents (and copies thereof) relating to the business of the
Company and its affiliates (including, without limitation, all acquisition
prospects, lists and contact information) which he may then possess or have
under her control.

          8.  Noncompetition and Nonsolicitation. Executive acknowledges that in
              ----------------------------------
the course of her employment with the Company he will become familiar with the
Company's and its Subsidiaries' trade secrets and with other confidential
information concerning the Company and such Subsidiaries and that her services
will be of special, unique and extraordinary value to the Company. Therefore,
Executive agrees that:

          (a) Noncompetition.  During the Employment Period and for a period of
              --------------
one year thereafter (the "Noncompete Period"), Executive shall not, within the
                          -----------------
United States, directly or indirectly own, manage, control, participate in,
consult with, render services for, or in any manner engage in any business
competing with the businesses of the Company or its Subsidiaries or any business
in which the Company or any of its Subsidiaries has requested and received
information relating to the acquisition of such business by the Company and the
Subsidiaries prior to the Separation; provided that passive ownership of less
                                      --------
than 5% of the outstanding stock of any publicly-traded corporation shall not,
in and of itself, be deemed to violate this Section 8(a); provided further that
                                                          --------
if the Executive's Employment with the Company is terminated by the Company
without Cause or the Executive resigns for Good Reason within a twenty four
month period a following a Sale of the Company, the one year period referenced
above shall be shortened to a six month period.

          (b) Nonsolicitation.  During the Noncompete Period, Executive shall
              ---------------
not directly or indirectly through another entity (i) induce or attempt to
induce any employee of the Company or its Subsidiaries to leave the employ of
the Company or such Subsidiary, or in any way interfere with

                                      -10-
<PAGE>

the relationship between the Company and any Subsidiary and any employee
thereof, (ii) hire any person who was an employee of the Company and any
Subsidiary within 180 days prior to the time such employee was hired by the
Executive, (iii) induce or attempt to induce any customer, supplier, licensee or
other business relation of the Company and any Subsidiary to cease doing
business with the Company or such Subsidiary or in any way interfere with the
relationship between any such customer, supplier, licensee or business relation
and the Company and any Subsidiary or (iv) directly or indirectly acquire or
attempt to acquire an interest in any business relating to the business of the
Company and any Subsidiary and with which the Company and any Subsidiary has
entertained discussions or has requested and received information relating to
the acquisition of such business by the Company and any Subsidiary in the two-
year period immediately preceding a Separation.

          (c) Enforcement.  If, at the time of enforcement of Section 7 or this
              -----------
Section 8, a court holds that the restrictions stated herein are unreasonable
under circumstances then existing, the parties hereto agree that the maximum
duration, scope or geographical area reasonable under such circumstances shall
be substituted for the stated period, scope or area and that the court shall be
allowed to revise the restrictions contained herein to cover the maximum
duration, scope and area permitted by law.  Because Executive's services are
unique and because Executive has access to confidential information, the parties
hereto agree that money damages would be an inadequate remedy for any breach of
this Agreement.  Therefore, in the event a breach or threatened breach of this
Agreement, the Company or its successors or assigns may, in addition to other
rights and remedies existing in their favor, apply to any court of competent
jurisdiction for specific performance and/or injunctive or other relief in order
to enforce, or prevent any violations of, the provisions hereof (without posting
a bond or other security).

          (d) Additional Acknowledgments.  Executive acknowledges that the
              --------------------------
provisions of this Section 8 are in consideration of:  (i) employment with the
Company, (ii) the issuance of the Executive Stock and (iii) additional good and
valuable consideration as set forth in this Agreement.  In addition, Executive
agrees and acknowledges that the restriction contained in Section 7 and this
Section 8 do not preclude Executive from earning a livelihood, nor do they
unreasonably impose limitations on Executive's ability to earn a living.  In
addition, Executive agrees and acknowledges that the potential harm to the
Company of the non-enforcement of Section 7 and this Section 8 outweighs any
potential harm to Executive of its enforcement by injunction or otherwise.
Executive acknowledges that he has carefully read this Agreement and has given
careful consideration to the restraints imposed upon Executive by this
Agreement, and is in full accord as to their necessity for the reasonable and
proper protection of confidential and proprietary information of the Company now
existing or to be developed in the future.  Executive expressly acknowledges and

borne by the party whose Fair Market Value 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.

Stockholders Agreement, dated as of March 23, 1999, by and among the Company,
the Investors, the Executive and certain other stockholders), upon receipt of an
undertaking by or on behalf of the Executive to repay such amount if it shall
ultimately be determined that the Executive is not entitled to indemnification
by the Company.

          (b) Transfers in Violation of Agreement.  Any Transfer or attempted
              -----------------------------------
Transfer of any Executive Stock in violation of any provision of this Agreement
shall be void, and the Company shall not record such Transfer on its books or
treat any purported transferee of such Executive Stock as the owner of such
stock for any purpose.

          (c) Severability.  Whenever possible, each provision of this Agreement
              ------------
will be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Agreement is held to be invalid, illegal or
unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or any other jurisdiction, but this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

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

          (e) Counterparts.  This Agreement may be executed in separate

              ----------------------
Agreement shall bind and inure to the benefit of and be enforceable by

assigns (including subsequent holders of Executive Stock); provided that the
rights and obligations of Executive under this Agreement shall not be assignable
except in connection with a permitted transfer of Executive Stock hereunder.

          (g) Choice of Law.  The laws of Delaware shall govern all issues
              -------------
concerning the relative rights of the Company and its stockholders and all other
questions concerning the construction, validity and interpretation of this
Agreement, without giving effect to any choice of law or other conflict of law
provision or rule (whether of the State of Delaware or any other jurisdiction)
that would cause the application of the laws of any jurisdiction other than the
State of Delaware.

          (h) Remedies.  Each of the parties to this Agreement (including the
              --------
Investors) will be entitled to enforce its rights under this Agreement
specifically, to recover damages and costs (including attorney's fees) caused by

damages

                                      -16-
<PAGE>

may not be an adequate remedy for any breach of the provisions of this Agreement
and that any party may in its sole discretion apply to any court of law or
equity of competent jurisdiction (without posting any bond or deposit) for
specific performance and/or other injunctive relief in order to enforce or
prevent any violations of the provisions of this Agreement.

on Executive in any amount or amounts considered available.  Executive agrees to
cooperate in any medical or other examination, supply any information, and to
execute and deliver any applications or other instruments in writing as may be
reasonably necessary to obtain and constitute such insurance.  Executive hereby
represents that he has no reason to believe that her life is not insurable at
rates now prevailing for healthy women of her age.

          (k) Business Days.  If any time period for giving notice or taking
              -------------
action hereunder expires on a day which is a Saturday, Sunday or holiday in the

7) shall survive a Separation and shall remain in full force and effect after
such Separation.

          (n) Generally Accepted Accounting Principles; Adjustments of Numbers.
              ----------------------------------------------------------------
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 generally accepted
accounting principles, consistently applied, except that if because of a change
in generally accepted accounting principles the Company would have to alter a
previously utilized accounting method or policy in order to remain in compliance
with generally accepted accounting principles, 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

Investors and/or any other Person acquiring securities) shall make available, at
the time and place and in the amount and form provided in this Agreement, the
consideration for the Executive Stock to be repurchased in accordance with the
provisions of this Agreement, then from and after such time, the person from
whom such shares are to be repurchased shall no longer have any rights as a
holder of such shares (other than the right to receive payment of such
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.

          (p) No Pledge or Security Interest.  The purpose of the Company's
              ------------------------------
retention of the Executive's stock certificates and executed stock powers is
solely to facilitate the repurchase provisions set forth in Section 3 herein and
does not constitute a pledge by the Executive of, or the granting of a security
interest in, the underlying stock.

          (q) Rights Granted to GTCR and its Affiliates.  Any rights granted to
              -----------------------------------------
GTCR and its Affiliates hereunder may also be exercised (in whole or in part) by
its designees (which may be Affiliates).

     meanings set forth in the Senior Management Agreement.
<PAGE>

          (c)  Optional Prepayments.  Maker may, at any time and from time to

time without premium or penalty, prepay all of the outstanding principal amount
of the Note; provided that any prepayment will be accompanied by a payment of
accrued interest on the portion being prepaid.

          (d)  Right of Offset.  Upon an Event of Default (as described in
               ---------------
Section 3 hereof) or the Company's repurchase of Executive Stock pursuant to

offset any amounts owed to the Company by the Maker, now existing or hereinafter
arising, pursuant to this Note against any amounts payable by the Company to the
Maker pursuant to and as set forth in the Management Agreement between the
Company and the Maker.

     3.   Events of Default.
          -----------------

          (a)  Definition. For purposes of this Note, an Event of Default shall
               ----------

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 her successors and assigns, hereby waives diligence,
presentment, protest and demand and notice of protest and demand, dishonor and
nonpayment of this Note, and expressly
<PAGE>

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

hereunder.

          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

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.

     8.   Governing Law.  This Note is made under and governed by the internal
          -------------
law, not the laws of conflicts, of the State of Delaware.

MEMORANDUM TO THE PERSONS ON THE
     ATTACHED DISTRIBUTION LIST


     Re: ZEFER Corp. (the "Company")

     As you know, the shares (the "Shares") of common stock of ZEFER Corp. (the
"Company") which you have purchased are subject to certain restrictions on
transfer under the Stock Restriction Agreement between yourself, the Company and
certain other parties thereto (the "Agreement"). The Agreement also gives the
Company the right, under certain circumstances to repurchase any or all of the
Shares (the "Restricted Shares") if your employment with the Company or its
subsidiaries terminates.

     Because of these restrictions, there are certain tax consequences regarding
your purchase of the Shares of which you should be aware. So long as your right
to retain the Restricted Shares is conditioned upon certain events, your
purchase of the Restricted Shares will result in no federal income tax
liability. However, when any Shares cease to be Restricted Shares, the excess of
the aggregate fair market value of those Shares at the time the restrictions
                                                ----------------------------
lapse over the aggregate amount you paid for them becomes taxable to you at
- -----
ordinary income rates in the year in which the restrictions lapse. Appreciation
in the value of the Shares after the date the restrictions lapse will be treated
as capital gain at the time the Shares are subsequently sold. The holding period
for determining whether such gain is long- or short-term begins when the
restrictions lapse.

     Pursuant to the provisions of Section 83(b) of the Internal Revenue Code,
however, you may elect to include in your gross income this year, and be taxed
upon, the difference between the current fair market value of the Shares and the
purchase price. Insofar as the purchase price you paid for the Shares is the
same as the fair market value, no tax would be owed. In addition, if you make
this election, no additional tax will be incurred until the Shares are disposed
of at a gain, and any appreciation from the date of purchase to the date of such
disposition will be taxed as a capital gain. Because the Company believes you
are paying a fair market value purchase price, it would appear to be to your
advantage to make a so-called Section 83(b) election since this election would
(i) not result in any current tax liability and (ii) allow any appreciation in
the value realized upon a future sale of the Shares to be taxed at capital gains
tax rates rather than ordinary income tax rates. While the Company believes you
are paying a fair market value purchase price, the question of fair market value
is necessarily subjective and the IRS may challenge this valuation. To the
extent such a challenge occurs and the IRS successfully argues that the fair
market value

<PAGE>

of the Restricted Shares is greater than the purchase price, the filing of a
Section 83(b) election would result in an immediate tax at ordinary income rates
on the difference.

      The Section 83(b) election can be made using the enclosed forms and must
be done no later than 30 days after purchase of the Shares. To make the
election, you should complete the four enclosed copies of the Election Form, and
          ----------------------------------------------------------------------
return them to us. Once we have verified receipt of all required documents from
- -----------------
you, we will file one form with the Internal Revenue Sevice on your behalf. Two
copies will be returned to you. You should file one copy with your federal
income tax return for the year in which the purchase occurred and retain the
last copy for your records.

     While we have attempted to summarize certain of the federal income tax
consequences of purchasing the shares, you are encouraged to consult your own
tax advisor for an examination of whether a Section 83(b) election is
appropriate for your individual circumstances. In addition, while state income
tax treatment generally follows the federal income tax treatment, please check
with your tax advisor for the availability and effect on making an equivalent
state election to the federal Section 83(b) election and for the requirements
for making such an election (filings, due dates, etc.).

     If you have any questions regarding the foregoing, please call either the
undersigned at 617/292-7888 or Ryan D. Darrah, Esq. of Ropes & Gray at
617/951-7823.

                    INCOME PURSUANT TO SECTION 83(b) OF THE
                             INTERNAL REVENUE CODE


          The undersigned purchased shares of Common Stock, par value $.01 per

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

 ------------
repurchase certain of the Shares at cost from the undersigned (or from the
holder of the Shares, if different from the undersigned) should the undersigned
cease to be employed by the Company and its subsidiaries or upon certain other
events. Hence, the Shares are subject to a substantial risk of forfeiture and
are non-transferable. The undersigned desires to make an election to have the
Shares taxed under the provision of Code (S)83(b) at the time he purchased the
Shares.

          Therefore, pursuant to Code (S)83(b) and Treasury Regulation (S)1.83-2
promulgated thereunder, the undersigned hereby makes an election, with respect
to the Shares (described below), to report as taxable income for calendar year
1999 the excess (if any) of the Shares' fair market value on May 21, 1999 over
the purchase price thereof.

          The following information is supplied in accordance with Treasury
Regulation (S)1.83-2(e):

          1.   The name, address and social security number of the undersigned:

               Social Security Number:
                                       -----------

          2.   A description of the property with respect to which the election
is being made:      shares of Common Stock, par value $.01 per share, of the
Company.

          3.   The date on which the property was transferred     . The taxable
year for which such election is made: calendar year     .

          4.   The restrictions to which the property is subject: If during the
first five years after the Closing Date, the undersigned ceases to be employed
by the Company or any of its subsidiaries, the unvested portion of the Shares
will be subject to repurchase by the Company at cost. 20% of the Shares become
vested shares on each of the first five annual anniversaries of the Closing
Date.
<PAGE>

          5.   The fair market value on May 21, 1999 of the property with
respect to which the election is being made, determined without regard to any
lapse restrictions:      per share of Common Stock.

          6.   The amount paid for such property:     per share of Common
Stock.

          A copy of this election has been furnished to the Secretary of the
Company pursuant to Treasury Regulations (S)1.83-2(e)(7).

                             EMPLOYMENT AGREEMENT
                             --------------------


          THIS EMPLOYMENT AGREEMENT (this "Agreement") is made as of  April 30,
                                           ---------
1999, between ZC Acquisition Corp., a Delaware corporation (the "Company"), and
                                                                 -------
Anthony Tjan ("Employee").
               --------

          The Company and Employee are parties to a certain Share Exchange
Agreement (the "Share Exchange Agreement") pursuant to which the Employee will
                ------------------------
be issued certain shares of  the Company's Common Stock, par value $.01 per
share (the "Common Stock").  All shares of Common Stock so issued to the
            ------------
Employee are referred to herein as "Employee Stock."   This Agreement contains
                                    --------------
certain restrictions with respect to the Employee Stock.  In addition, the
Company desires to employ the Employee and the Employee desires to be employed
by the Company.  Certain definitions are set forth in Section 10 of this
Agreement.

          The execution and delivery of this Agreement by the Company and
Employee is a condition to the purchase of shares of Common Stock and shares of
the Class A Preferred by GTCR Fund VI, L.P., a Delaware limited partnership
("GTCR"), GTCR VI Executive Fund, L.P., a Delaware limited partnership
  ----
("Employee Fund") and GTCR Associates VI, a Delaware general partnership
  -------------
("Associates Fund") (each an "Investor" and collectively, the "Investors")
  ---------------             --------                         ---------
pursuant to a purchase agreement between the Company and the Investors dated as
of the date hereof (the "Purchase Agreement").  Certain provisions of this
                         ------------------
Agreement are intended for the benefit of, and will be enforceable by, 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 EMPLOYEE STOCK

          1.   Issuance of Employee Stock.
               --------------------------

          (a)  Upon execution of this Agreement, the Company will deliver to
Employee a certificate representing 211,200 shares of Common Stock and Employee
shall be deemed to have paid fair market value for such shares pursuant to the
Share Exchange Agreement.

          (b)  Within 30 days after the date hereof, Employee will make an
effective election with the Internal Revenue Service under Section 83(b) of the
Internal Revenue Code and
<PAGE>

the regulations promulgated thereunder in the form of Exhibit A attached
                                                      ---------
hereto.

          (c)  Until the occurrence of a Sale of the Company or a Public
Offering, all certificates evidencing shares of Employee Stock shall be held by
the Company for the benefit of the Employee and the other holder(s) of Employee
Stock.  Upon the occurrence of a Sale of the Company or a Public Offering, the
Company will return the certificates for the Employee Stock to the record
holders thereof.

          (d)  In connection with the issuance of the Employee Stock, Employee
represents and warrants to the Company that:

               (i)   The Employee Stock to be acquired by Employee pursuant to
     the Share Exchange Agreement will be acquired for Employee'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
     Employee Stock will not be disposed of in contravention of the Securities
     Act or any applicable state securities laws.

               (ii)  Employee is sophisticated in financial matters and is able
     to evaluate the risks and benefits of the investment in the Employee Stock.

               (iii) Employee is able to bear the economic risk of his
     investment in the Employee Stock for an indefinite period of time because
     the Employee 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)  Employee has had an opportunity to ask questions and
     receive answers concerning the terms and conditions of the offering of
     Employee Stock and has had full access to such other information concerning
     the Company as he has requested.

               (v)   This Agreement constitutes the legal, valid and binding
     obligation of Employee, enforceable in accordance with its terms, and the
     execution, delivery and performance of this Agreement by Employee does not
     and will not conflict with, violate or cause a breach of any agreement,
     contract or instrument to which Employee is a party or any judgment, order
     or decree to which Employee is subject.

               (vi)  Employee 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 Employee is a party to or by which
     Employee is bound.

                                      -2-
<PAGE>

               (vii) Employee is a resident of the Commonwealth of
     Massachusetts.

          (e)  As an inducement to the Company to issue the Employee Stock to
Employee, and as a condition thereto, Employee acknowledges and agrees that
neither the issuance of the Employee Stock to Employee nor any provision
contained herein shall entitle Employee to remain in the employment of the
Company or any of its Subsidiaries or affect the right of the Company to
terminate Employee's employment at any time for any reason.

          (f)  Concurrently with the execution of this Agreement, (i) Employee
shall execute in blank ten stock transfer powers in the form of Exhibit B
                                                                ---------
attached hereto (the "Stock Powers") with respect to the Employee 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 Employee
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
Employee's spouse shall execute the consent in the form of Exhibit C attached
                                                           ---------
hereto.

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

          (a)  All of the shares of Employee Stock acquired hereunder shall be
subject to vesting in the manner specified in this Section  2.  Except as
otherwise provided in Sections 2(b) and 2(c) below, the Employee Stock will
become vested in accordance with the following schedule (the "Vesting

          3.   Repurchase Option.
               -----------------

          (a)  In the event Employee ceases to be employed by the Company and
its Subsidiaries for any reason (the "Separation"), the Employee Stock (whether
                                      ----------
held by Employee or one or more of Employee'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 Employee Stock will be Employee's Original Cost for such share
and (ii) the purchase price for each Vested Share of Employee Stock will be the
Fair Market Value for such share as at the date of the Separation; provided,
                                                                   --------
however, that if Employee's employment is terminated with Cause, the purchase
- -------
price for each Vested Share of Employee Stock will be Employee's Original Cost
for such share.

          (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 Employee Stock within 120
 -----------------
days after the Separation.  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 Employee Stock held
by Employee at the time of delivery of the Repurchase Notice.  If the number of
shares of Employee Stock then held by Employee is less than the total number of
shares of Employee 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 Employee Stock under this Agreement, pro rata according to the
number of shares of Employee 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

                                      -5-

the number of shares of Employee Stock to be purchased from such person.

          (d)  If for any reason the Company does not elect to purchase all of
the Employee Stock pursuant to the Repurchase Option, all employees and/or
executives of the Company who are parties to an agreement with the Company which
is substantially similar in form and substance to this Agreement (each a "Senior
                                                                          ------

Separation or Triggering Event and the Investors shall be entitled to exercise
the Repurchase Option for all or any portion of the shares of Employee 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 Employee Stock as to the 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 Employee 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 Employee Stock to be purchased by each of them.

          (e)  The closing of the purchase of the Employee 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 Employee Stock

case of Employee Stock to be repurchased at Fair Market Value, a subordinate

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 Employee to the Company. Each Senior Manager and each Investor will pay
for the Employee 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 Employee Stock.

          (f)  Notwithstanding anything to the contrary contained in this
Agreement, all repurchases of Employee 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 Employee 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 Employee Stock is finally
determined to be an amount at least 10% greater than the per share repurchase
price for such share of Employee Stock in the Repurchase Notice or in the
Supplemental Repurchase Notice, each of the Company and the Investors shall have
the right to revoke its exercise of the Repurchase Option for all or any portion
of the Employee Stock elected to be repurchased by it by delivering notice of
such revocation in writing to the holders of Employee Stock during the thirty-
day period beginning on the date that the Company and/or the Investors are given
written notice that the Fair Market Value of a share of Employee Stock was
finally determined to be an amount at least 10% greater than the per share
repurchase price for Employee Stock set forth in the Repurchase Notice or in the
Supplemental Repurchase Notice.

          (b)  Certain Permitted Transfers.  The restrictions in this Section 4
               ---------------------------
will not apply with respect to any Transfer of Employee Stock if made (i)
pursuant to applicable laws of descent and distribution or to such Person's
legal guardian in the case of any mental incapacity or among such Person's
Family Group, or (ii) at a time when (A) the Common Stock of the Company has
been trading for at least 45 consecutive days (including the day immediately
preceding such Transfer) at a price that exceeds the initial Public Offering

but in the case of this clause (ii) only an amount of shares per calendar year
up to the lesser of (x) the number of Vested Shares owned by Employee at the
time of such Transfer and (y) 10% of the total number of shares of Common Stock

and the number of shares of Common Stock which the Employee has a right to
Transfer pursuant to clause (iii) above shall be reduced by the number of shares
of Common Stock which the Employee has Transferred in such calendar year
pursuant to clause (ii) above.  Notwithstanding anything in this Section 4 to
the contrary, the  restrictions contained in this Section 4 will continue to be
applicable to the Employee Stock after any Transfer of the type referred to in
clause (i) and the transferees of such Employee Stock will agree in writing to
be bound by the provisions of this Agreement.  Any transferee of Employee Stock
pursuant to a transfer in accordance with the provisions of this Section 4(b)(i)
is herein referred to as a "Permitted Transferee."  Upon the transfer of
                            --------------------

In the case of a Transfer pursuant to clause (i) hereof, the Transfer Notice
will disclose in reasonable detail the identity of the Permitted Transferee(s).

          (c)  Termination of Restrictions.  The restrictions set forth in this
               ---------------------------
Section 4 will continue with respect to each share of Employee Stock until the
earlier of (i) the date on which such share of Employee Stock has been
transferred in a Public Sale permitted by this Section 4, or (ii) the
consummation of an Approved Sale.

          5.   Additional Restrictions on Transfer of Employee Stock.
               -----------------------------------------------------

          (a)  Legend.  The certificates representing the Employee Stock will
               ------
bear a legend in substantially the following form:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ORIGINALLY
     ISSUED AS OF APRIL 30, 1999, HAVE NOT BEEN REGISTERED UNDER THE
     SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT BE
     SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
     STATEMENT UNDER THE ACT OR AN EXEMPTION FROM REGISTRATION
     THEREUNDER. THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE
     ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER, CERTAIN
     REPURCHASE OPTIONS AND CERTAIN OTHER AGREEMENTS SET FORTH IN AN
     EMPLOYMENT AGREEMENT BETWEEN THE COMPANY AND AN EMPLOYEE OF THE
     COMPANY DATED AS OF APRIL 30, 1999.

          (b)  Opinion of Counsel.  No holder of Employee Stock may sell,
               ------------------
transfer or dispose of any Employee Stock (except pursuant to an effective
registration statement under the Securities Act) without first delivering to the
Company an 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 Employee Stock delivers to the
Company an opinion of counsel that no subsequent transfer of such Employee Stock
shall require registration under the Securities Act, the Company shall promptly
upon such contemplated transfer deliver new certificates for such Employee 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
Employee 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.

Employee shall devote his or her best efforts and his or her full business time
and attention to t he business and affairs of the Company and its subsidiaries.

                                              ------------------
per annum, subject to any increase as determined in the discretion of the
President based upon the Company's achievements of budgetary and other
objectives set by the Board.  As soon as

                                      -10-
<PAGE>

practicable following the date hereof, the Company agrees to review Employee's
Annual Base Salary in light of certain objective criteria (determined in its
sole discretion), and may (but shall have no obligation to) adjust such Annual
Base Salary as the Company deems appropriate in its sole discretion. Employee's
Annual Base Salary for any partial year will be prorated based upon the number
of days elapsed in such year. During the Employment Period, the Employee shall
also be eligible for an annual bonus of 35% of Employee's then applicable Annual
Base Salary for such year based upon Employee's attainment of individual
performance objectives and the Company's attainment of its budgetary objectives

Employee's  resignation, disability (as determined by the President in his good
faith judgment) or death or until the President decides to terminate Employee's
employment.

          (d)  Payments in the Event of Separation.  In the event of a
               -----------------------------------
Separation, the Company shall pay to the Employee, in a lump sum within 15 days
after such termination or resignation, an amount equal to the sum of (A) any
unpaid base salary owed to the Employee for services performed prior to such
termination, plus (B) the amount of any compensation previously deferred by the
Employee (together with any accrued interest or earnings thereon) and any
accrued vacation pay, in each case to the extent not previously paid (the
obligations set forth in clauses (A) and (B) are collectively referred to herein
as the "Accrued Obligations").
        -------------------

          7.   Confidential Information. Employee acknowledges that the
               ------------------------
information, observations and data obtained by him during the course of his
performance under this Agreement concerning the business and affairs of the
Company and its affiliates are the property of the Company, including
information concerning acquisition opportunities in or reasonably related to the
Company's business or industry of which Employee becomes aware during the
Employment Period. Therefore, Employee agrees that he will not disclose to any
unauthorized person or use for his own account any of such information,
observations or data without the Board's written consent, unless and to the
extent that the aforementioned matters become generally known to and available
for use by the public other than as a result of Employee's acts or omissions to
act. Employee agrees to deliver to the Company at a Separation, or at any other
time the Company may request in writing, all memoranda, notes, plans, records,
reports and other documents (and copies thereof) relating to the business of the
Company and its affiliates (including, without limitation, all acquisition
prospects, lists and contact information) which he

                                      -11-
<PAGE>

may then possess or have under his control.

          8.   Noncompetition and Nonsolicitation.   Employee acknowledges
               ----------------------------------
that in the course of his employment with the Company he will become familiar
with the Company's and its Subsidiaries' trade secrets and with other
confidential information concerning the Company and such Subsidiaries and that
his services will be of special, unique and extraordinary value to the Company.
Therefore, Employee agrees that:

          (a)  Noncompetition.  During the Employment Period and for a period of
               --------------
one year thereafter (the "Noncompete Period"), Employee shall not, within the
                          -----------------
United States, directly or indirectly own, manage, control, participate in,
consult with, render services for, or in any manner engage in any business
engaged in Internet consulting or implementation services (or any other business
directly competitive with a portion of the business of the Company or its
Subsidiaries in which Employee has participated substantially) or any business
in which the Company or any of its Subsidiaries has requested and received
information relating to the acquisition of such business by the Company and the
Subsidiaries prior to the Separation; provided that passive ownership of less
than 5% of the outstanding stock of any publicly-traded corporation shall not,
in and of itself, be deemed to violate this Section 8(a).

          (b)  Nonsolicitation. During the Noncompete Period, Employee shall not
               ---------------
directly or indirectly through another entity (i) induce or attempt to induce
any employee of the Company or its Subsidiaries to leave the employ of the
Company or such Subsidiary, or in any way interfere with the relationship
between the Company and any Subsidiary and any employee thereof, (ii) hire any
person who was an employee of the Company and any Subsidiary within 180 days
prior to the time such employee was hired by the Employee, (iii) induce or
attempt to induce any customer, supplier, licensee or other business relation of
the Company and any Subsidiary to cease doing business with the Company or such
Subsidiary or in any way interfere with the relationship between any such
customer, supplier, licensee or business relation and the Company and any
Subsidiary or (iv) directly or indirectly acquire or attempt to acquire an
interest in any business relating to the business of the Company and any
Subsidiary and with which the Company and any Subsidiary has entertained
discussions or has requested and received information relating to the
acquisition of such business by the Company and any Subsidiary in the two-year
period immediately preceding a Separation.

          (c)  Enforcement.  If, at the time of enforcement of Section 7 or this
               -----------
Section 8,

                                      -12-
<PAGE>

a court holds that the restrictions stated herein are unreasonable under
circumstances then existing, the parties hereto agree that the maximum duration,
scope or geographical area reasonable under such circumstances shall be
substituted for the stated period, scope or area and that the court shall be
allowed to revise the restrictions contained herein to cover the maximum
duration, scope and area permitted by law. Because Employee's services are
unique and because Employee has access to confidential information, the parties
hereto agree that money damages would be an inadequate remedy for any breach of
this Agreement. Therefore, in the event a breach or threatened breach of this
Agreement, the Company or its successors or assigns may, in addition to other
rights and remedies existing in their favor, apply to any court of competent
jurisdiction for specific performance and/or injunctive or other relief in order
to enforce, or prevent any violations of, the provisions hereof (without posting
a bond or other security).

          (d)  Additional Acknowledgments.  Employee acknowledges that the
               --------------------------
provisions of this Section 8 are in consideration of: (i) the consideration set
forth in the Share Exchange Agreement, (ii) employment with the Company, (iii)
the issuance of the Employee Stock and (iv) additional good and valuable
consideration as set forth in this Agreement. In addition, Employee agrees and
acknowledges that the restrictions contained in Section 7 and this Section 8 do
not preclude Employee from earning a livelihood, nor do they unreasonably impose
limitations on Employee's ability to earn a living. In addition, Employee agrees
and acknowledges that the potential harm to the Company of the non-enforcement
of Section 7 and this Section 8 outweighs any potential harm to Employee of its
enforcement by injunction or otherwise. Employee acknowledges that he has
carefully read this Agreement and has given careful consideration to the
restraints imposed upon Employee by this Agreement, and is in full accord as to
their necessity for the reasonable and proper protection of confidential and
proprietary information of the Company now existing or to be developed in the
future. Employee expressly acknowledges and agrees that each and every restraint
imposed by this Agreement is reasonable with respect to subject matter, time
period and geographical area.

          (e)  Election as Director.  The Company shall cause Employee to be
               --------------------
elected as a Class I Director of the Company as soon as practicable after the
date hereof.

names of four nationally recognized investment banking firms, and each party
shall be entitled to strike two names from the other party's list of firms, and
the appraiser shall be selected by lot from the remaining four investment
banking firms. The expenses of such appraiser shall be borne by the party whose
Fair Market Value 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.

for any purpose.

          (c)  Severability.  Whenever possible, each provision of this

otherwise provided) shall be made in accordance with generally accepted
accounting principles, consistently applied, except that if because of a change

first four years after the Closing Date, the undersigned ceases to be employed
by the Company or any of
<PAGE>

its subsidiaries, the unvested portion of the Shares will be subject to
repurchase by the Company at cost. 20% of the Shares become vested shares on
each of the first and second anniversaries of the Closing Date and 30% of the
Shares become vested on each of the third and fourth anniversary thereof.

          5.   The fair market value on April __, 1999 of the property with
respect to which the election is being made, determined without regard to any
lapse restrictions: $.50 per share of Common Stock.

          6.   The amount paid for such property: $.50 per share of Common

                          SENIOR MANAGEMENT AGREEMENT
                          ---------------------------


          This SENIOR MANAGEMENT AGREEMENT (this "Agreement") is made as of May
                                                  ---------
21, 1999, between ZEFER Corp., a Delaware corporation (the "Company"), and
                                                            -------
Frank Torbey ("Executive").
               ---------

          The Company and Executive desire to enter into an agreement pursuant
to which Executive will purchase, and the Company will sell, up to 110,000
shares of the Company's Common Stock, par value $.01 per share (the "Common
                                                                     ------
Stock"). All shares of Common Stock acquired by Executive are referred to
- -----
herein as "Executive Stock."  In addition, the Company desires to employ the
           ---------------
Executive and the Executive desires to be employed by the Company. Certain
definitions are set forth in Section 10 of this Agreement.

          The execution and delivery of this Agreement by the Company and
Executive was contemplated as a condition to the purchase of shares of Common
Stock and shares of the Class A Preferred by 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") pursuant to a purchase agreement between the Company and the
- ----------
Investors dated as of March 23, 1999 (the "Purchase Agreement"). Certain
                                           ------------------
provisions of this Agreement are intended for the benefit of, and will be
enforceable by, 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 EXECUTIVE STOCK

          1.   Purchase and Sale of Executive Stock.
               ------------------------------------

          (a)  Upon execution of this Agreement, Executive will purchase, and
the Company will sell, 110,000 shares of Common Stock at a price of $.50 per
share. The Company will deliver to Executive the certificates representing such
Executive Stock, and Executive will deliver to the Company a cashier's or
certified check or wire transfer of funds in the aggregate amount of $4,826.25
and a promissory note in the form of Exhibit A attached hereto in an aggregate
                                     ---------
principal amount of $50,173.75 (the "Executive Note").
                                     --------------

          (b)  Within 30 days after the date hereof, Executive will make an
effective election with the Internal Revenue Service under Section 83(b) of the
Internal Revenue Code and the regulations promulgated thereunder in the form of
Exhibit B attached hereto.
- ---------
<PAGE>

          (c)  Until the occurrence of a Sale of the Company or a Public
Offering, all certificates evidencing shares of Executive Stock shall be held by
the Company for the benefit of the Executive and the other holder(s) of
Executive Stock. Upon the occurrence of a Sale of the Company or a Public
Offering, the Company will return the certificates for the Executive Stock to
the record holders thereof.

          (d)  In connection with the purchase and sale of the Executive Stock,
Executive represents and warrants to the Company that:

               (i)   The Executive Stock to be acquired by Executive pursuant to
     this Agreement will be acquired for Executive's own account and not with a
     view to, or intention of, distribution thereof in violation of the
     Securities Act, or any applicable state securities laws, and the Executive
     Stock will not be disposed of in contravention of the Securities Act or any
     applicable state securities laws.

               (ii)  Executive is an executive officer of the Company, is
     sophisticated in financial matters and is able to evaluate the risks and
     benefits of the investment in the Executive Stock.

               (iii) Executive is able to bear the economic risk of his
     investment in the Executive Stock for an indefinite period of time because
     the Executive Stock has not been registered under the Securities Act and,
     therefore, cannot be sold unless subsequently registered under the
     Securities Act or an exemption from such registration is available.

               (iv)  Executive has had an opportunity to ask questions and
     receive answers concerning the terms and conditions of the offering of
     Executive Stock and has had full access to such other information
     concerning the Company as he has requested.

               (v)   This Agreement constitutes the legal, valid and binding
     obligation of Executive, enforceable in accordance with its terms, and the
     execution, delivery and performance of this Agreement by Executive does not
     and will not conflict with, violate or cause a breach of any agreement,
     contract or instrument to which Executive is a party or any judgment, order
     or decree to which Executive is subject.

               (vi)  Executive 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 Executive is a party to or by which
     Executive is bound.

               (vii) Executive is a resident of the State of Massachusetts.

          (e)  As an inducement to the Company to issue the Executive Stock to
Executive, and as a condition thereto, Executive acknowledges and agrees that
neither the issuance of the

                                      -2-
<PAGE>

Executive Stock to Executive nor any provision contained herein shall entitle
Executive to remain in the employment of the Company or any of its Subsidiaries
or affect the right of the Company to terminate Executive's employment at any
time for any reason, subject, however, to the terms of this Agreement.

          (f)  Concurrently with the execution of this Agreement, (i) Executive
shall execute in blank ten stock transfer powers in the form of Exhibit C
                                                                ---------
attached hereto (the "Stock Powers") with respect to the Executive 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 Executive
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
Executive's spouse shall execute the consent in the form of Exhibit D attached
                                                            ---------
hereto.

          2.   Vesting of Executive Stock.
               --------------------------

          (a)  All of the shares of Executive Stock acquired hereunder shall be
subject to vesting in the manner specified in this Section  2. Except as
otherwise provided in Sections 2(b) and 2(c) below, the Executive  Stock will
become vested in accordance with the following schedule (the "Vesting
                                                              -------
Schedule"), if as of each such date Executive is still employed by the Company
- --------
or any of its Subsidiaries:


               Date                              Cumulative Percentage of
               ----                            Executive 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 Executive is still employed by the Company or any
of its Subsidiaries, the Executive 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%


                                      -3-
<PAGE>

     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 Executive Stock will vest on each subsequent June 30, September 30,
     December 31 and March 31 so that the Executive Stock will be 100% vested on
     March 31, 2004.

  (c)     Upon the occurrence of a Transaction, all shares of Executive 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 Executive Stock which have
          become vested are referred to herein as "Vested Shares" and all other
                                                   -------------
          shares of Executive Stock are referred to herein as "Unvested Shares."
                                                               ---------------

          3.   Repurchase Option.
               -----------------

          (a)  In the event (i) Executive ceases to be employed by the Company
and its Subsidiaries for any reason (the "Separation") or (ii) Executive fails
                                          ----------
to make any principal or interest payment under the Executive Note after such
payment becomes due and after giving effect to any applicable grace period (a
"Triggering Event"), the Executive Stock (whether held by Executive or one or
 ----------------
more of Executive'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 Executive Stock will be Executive's Original Cost for such
share and (ii) the purchase price for each Vested Share of Executive Stock will
be the Fair Market Value for such share as at the date of the Separation;
provided, however, that if Executive's employment is terminated with Cause, the
- --------  -------
purchase price for each Vested Share of Executive Stock will be Executive'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 Executive Stock (whether a Vested Share or
Unvested Share) will be Executive'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 Executive 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

                                      -4-
<PAGE>

holder, the aggregate consideration to be paid for such shares and the time and
place for the closing of the transaction. The number of shares to be repurchased
by the Company shall first be satisfied to the extent possible from the shares
of Executive Stock held by Executive at the time of delivery of the Repurchase
Notice. If the number of shares of Executive Stock then held by Executive is
less than the total number of shares of Executive Stock which the Company has
elected to purchase, the Company shall purchase the remaining shares elected to
be purchased from the other holder(s) of Executive Stock under this Agreement,
pro rata according to the number of shares of Executive Stock held by such other
holder(s) at the time of delivery of such Repurchase Notice (determined as
nearly as practicable to the nearest share). The number of Unvested Shares and
Vested Shares to be repurchased hereunder will be allocated among Executive and
the other holders of Executive Stock (if any) pro rata according to the number
of shares of Executive Stock to be purchased from such person.

          (d)  If for any reason the Company does not elect to purchase all of
the Executive Stock pursuant to the Repurchase Option, all other 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 Executive 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
Executive Stock as to the 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 Executive 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 Executive Stock to be purchased by each of them.

          (e)  The closing of the purchase of the Executive Stock pursuant to
the Repurchase Option shall take place on the date designated by the Company in
the Repurchase Notice

                                      -5-
<PAGE>

or Supplemental Repurchase Notice, which date shall not be more than one month
nor less than five days after the delivery of the later of either such notice to
be delivered. The Company will pay for the Executive Stock to be repurchased by
it pursuant to the Repurchase Option with (i) a check or wire transfer of funds
for (A) any shares of Executive Stock to be repurchased at Executive's Original
Cost and (B) in the case of Executive Stock to be repurchased at Fair Market
Value, that portion of such Executive Stock which is equal to the Executive's
Original Cost, and (ii) in the case of Executive Stock to be repurchased at Fair
Market Value, a subordinate note or notes for that portion of such Executive
Stock which exceeds the Executive'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 Executive to the Company. Each Senior Manager and each
Investor will pay for the Executive 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 Executive Stock.

          (f)  Notwithstanding anything to the contrary contained in this
Agreement, all repurchases of Executive Stock by the Company shall be subject to
applicable restrictions contained in the Delaware General Corporation Law and in
the Company's and its Subsidiaries' debt and equity financing agreements. If any
such restrictions prohibit the repurchase of Executive Stock hereunder which the
Company is otherwise entitled or required to make, the Company may make such
repurchases as soon as it is permitted to do so under such restrictions.

          (g)  Notwithstanding anything to the contrary contained in this
Agreement, if the Fair Market Value of a share of Executive Stock is finally
determined to be an amount at least 10% greater than the per share repurchase
price for such share of Executive Stock in the Repurchase Notice or in the
Supplemental Repurchase Notice, each of the Company and the Investors shall have
the right to revoke its exercise of the Repurchase Option for all or any portion
of the Executive Stock elected to be repurchased by it by delivering notice of
such revocation in writing to the holders of Executive Stock during the thirty-
day period beginning on the date that the Company and/or the Investors are given
written notice that the Fair Market Value of a share of Executive Stock was
finally determined to be an amount at least 10% greater than the per share
repurchase price for Executive 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 Executive Stock.

Section 4(b) below.

          (b)  Certain Permitted Transfers.  The restrictions in this Section 4
               ---------------------------
will not apply with respect to any Transfer of Executive Stock if made (i)
pursuant to applicable laws of descent and distribution or to such Person's
legal guardian in the case of any mental incapacity or among such Person's
Family Group, or (ii) at a time when (A) the Common Stock of the Company has
been trading for at least 45 consecutive days (including the day immediately
preceding such Transfer) at a price that exceeds the initial Public Offering
price by at least 20% and (B) the Common Stock bid and asked price on the day of
such Transfer was at least 20% greater than the initial Public Offering price,
but in the case of this clause (ii) only an amount of shares per calender year

time of such Transfer and (y) 10% of the total number of shares of Common Stock
owned by Executive at the time of the Company's initial Public Offering, or
(iii) at such time as the Investors sell shares of Common Stock in a Public
Sale, but in the case of this clause (iii) only an amount of shares (the
"Transfer Amount") equal to the lesser of (C) the number of Vested Shares of

Common Stock owned by Executive at the time of such Transfer and (D) the number
of shares of Common Stock owned by Executive multiplied by a fraction (the
"Transfer Fraction"), the numerator of which is the number of shares of Common
- ------------------
Stock sold by the Investors in such Public Sale and the denominator of which is
the total number of shares of Common Stock held by the Investors prior to the
Public Sale; provided that, if at the time of a Public Sale of shares by the
             -------- ----
Investors, Executive chooses not to Transfer the Transfer Amount, Executive
shall retain the right to Transfer an amount of Executive Stock at a future date
equal to the lesser of (x) the number of Vested Shares owned by Executive at
such future date and (y) the number of shares of Executive Stock owned by
Executive at such future date multiplied by the Transfer Fraction; provided
                                                                   --------

continue to be applicable to the Executive Stock after any Transfer of the type

may pledge up to $2 million worth of Vested Shares as collateral for a loan so
long as the pledgee of such stock and the Executive enter into a pledge
agreement in form and substance reasonably satisfactory to the Board of
Directors of the Company (the "Board"), pursuant to which pledgee, among other
things, agrees that pledgee may only sell such stock in a Public Sale.

          (c)  Termination of Restrictions.  The restrictions set forth in this
               ---------------------------
Section 4 will continue with respect to each share of Executive Stock until the
earlier of (i) the date on which such share of Executive Stock has been
transferred in a Public Sale permitted by this Section 4, or (ii) the

          5.   Additional Restrictions on Transfer of Executive Stock.
               ------------------------------------------------------

          (a)  Legend.  The certificates representing the Executive Stock will
               ------
bear a legend in substantially the following form:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE 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
                                              ---
     SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
     STATEMENT UNDER THE ACT OR AN EXEMPTION FROM REGISTRATION
     THEREUNDER. THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE
     ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER, CERTAIN
     REPURCHASE OPTIONS AND CERTAIN OTHER AGREEMENTS SET FORTH IN A
     SENIOR MANAGEMENT AGREEMENT BETWEEN THE COMPANY AND AN EXECUTIVE
     OF THE COMPANY DATED AS OF MAY 21, 1999. A COPY OF SUCH AGREEMENT
     MAY BE OBTAINED BY THE HOLDER HEREOF AT THE COMPANY'S PRINCIPAL
     PLACE OF BUSINESS WITHOUT CHARGE."

          (b)  Opinion of Counsel.  No holder of Executive Stock may sell,
               ------------------
transfer or dispose of any Executive Stock (except pursuant to an effective
registration statement under the Securities Act) without first delivering to the
Company an 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 Executive Stock delivers to the
Company an opinion of counsel that no subsequent transfer of such Executive
Stock shall require registration under the Securities Act, the Company shall
promptly upon such contemplated transfer deliver new certificates for such
Executive 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 Executive Stock not bearing such legend, the holder
thereof shall not transfer the same until the prospective transferee has
confirmed to the Company in

                                      -8-

annual base salary of the Company's other executives as required by such
executives' respective management agreements, and (ii) that its pro forma

from his position with the Company for Good Reason, then the Executive shall be
entitled to the following:

     in 15 days after such termination or resignation, an amount equal to the
     sum of (A) any unpaid base salary owed to the Executive for services
     performed prior to such termination, plus (B) the amount of any
     compensation previously deferred by the Executive (together with any
     accrued interest or earnings thereon) and any accrued vacation pay, in each
     case to the extent not previously paid (the obligations set forth in
     clauses (A) and (B) are collectively referred to herein as the "Accrued
                                                                     -------
     Obligations");
     -----------

               (ii)  the Company shall pay each month to the Executive,
     beginning on the date of the first normal executive payroll of the Company
     that occurs more than 30 days after such termination or resignation, an
     amount equal to one-twelfth (1/12) of the Executive's Annual Base Salary as
     of the date immediately before such termination or resignation; provided
                                                                     --------
     however, that such payments shall immediately cease upon the earliest to
     -------
     occur of (x) the Executive's death and (y) the six month anniversary of
     such termination or resignation. Notwithstanding anything in this Section
     6(d) to the contrary, in the event that the Executive becomes employed with
     another employer, then the payments to be made by the Company pursuant to
     this Section 6(d)(ii) shall be reduced (on a dollar for dollar basis) in an
     amount equal to the cash compensation received by Executive from such
     employer; and

               (iii)  the Company shall continue to provide medical insurance
     benefits to the Executive and to the Executive's family at least equal to
     those medical insurance benefits that would have been provided to them in
     the absence of such termination or resignation; provided however, that such
                                                     -------- -------
     payments shall immediately cease upon the earliest to occur of (x) the
     Executive's death and (y) the six month anniversary of such termination or
     resignation.  Notwithstanding anything in this Section 6(d) to the
     contrary, in the event that the Executive becomes employed with another
     employer and is eligible for medical insurance benefits under another
     employer-provided plan, then the medical insurance benefits to be provided
     by the Company pursuant to this Section 6(d)(iii) shall be reduced to the
     extent that the Executive and his family is eligible to receive medical
     insurance benefits under such other employer-provided plan.

          (e)  Other Separations.  In the event of a Separation other than a
               -----------------
termination by the Company without cause or a resignation by the Executive for
Good Reason, the Company shall pay to the Executive (or his estate, if
applicable), in a lump sum in cash within 15 days after such Separation, an
amount equal to any Accrued Obligations.

          7.   Confidential Information.  Executive acknowledges that the
               ------------------------
information, observations and data obtained by him during the course of his
performance under this Agreement concerning the business and affairs of the
Company and its affiliates are the property of the

                                      -10-
<PAGE>

Company, including information concerning acquisition opportunities in or
reasonably related to the Company's business or industry of which Executive
becomes aware during the Employment Period. Therefore, Executive agrees that he
will not disclose to any unauthorized person or use for his own account any of
such information, observations or data without the Company's written consent,
unless and to the extent that the aforementioned matters become generally known
to and available for use by the public other than as a result of Executive's
acts or omissions to act. Executive agrees to deliver to the Company at a
Separation, or at any other time the Company may request in writing, all
memoranda, notes, plans, records, reports and other documents (and copies
thereof) relating to the business of the Company and its affiliates (including,
without limitation, all acquisition prospects, lists and contact information)
which he may then possess or have under his control.

          8.   Noncompetition and Nonsolicitation.   Executive acknowledges
               ----------------------------------
that in the course of his employment with the Company he will become familiar
with the Company's and its Subsidiaries' trade secrets and with other
confidential information concerning the Company and such Subsidiaries and that
his services will be of special, unique and extraordinary value to the Company.
Therefore, Executive agrees that:

          (a)  Noncompetition.  During the Employment Period and for a period of
               --------------
one year thereafter (the "Noncompete Period"), Executive shall not, within the
                          -----------------
United States, directly or indirectly own, manage, control, participate in,
consult with, render services for, or in any manner engage in any business
competing with the businesses of the Company or its Subsidiaries or any business
in which the Company or any of its Subsidiaries has requested and received
information relating to the acquisition of such business by the Company and the
Subsidiaries prior to the Separation; provided that passive ownership of less
                                      --------
than 5% of the outstanding stock of any publicly-traded corporation shall not,
in and of itself, be deemed to violate this Section 8(a); provided further that
                                                          --------
if the Executive's Employment with the Company is terminated by the Company
without Cause or the Executive resigns for Good Reason within a twenty four
month period a following a Sale of the Company, the one year period referenced
above shall be shortened to a six month period.

          (b)  Nonsolicitation.  During the Noncompete Period, Executive shall
               ---------------
not directly or indirectly through another entity (i) induce or attempt to
induce any employee of the Company or its Subsidiaries to leave the employ of
the Company or such Subsidiary, or in any way interfere with the relationship
between the Company and any Subsidiary and any employee thereof, (ii) hire any
person who was an employee of the Company and any Subsidiary within 180 days
prior to the time such employee was hired by the Executive, (iii) induce or
attempt to induce any customer, supplier, licensee or other business relation of
the Company and any Subsidiary to cease doing business with the Company or such
Subsidiary or in any way interfere with the relationship between any such
customer, supplier, licensee or business relation and the Company and any
Subsidiary or (iv) directly or indirectly acquire or attempt to acquire an
interest in any business relating to the business of the Company and any
Subsidiary and with which the Company and any Subsidiary has entertained
discussions or has requested and received information relating to the
acquisition of such

                                      -11-
<PAGE>

business by the Company and any Subsidiary in the two-year period immediately
preceding a Separation.

          (c)  Enforcement.  If, at the time of enforcement of Section 7 or this
               -----------
Section 8, a court holds that the restrictions stated herein are unreasonable
under circumstances then existing, the parties hereto agree that the maximum
duration, scope or geographical area reasonable under such circumstances shall
be substituted for the stated period, scope or area and that the court shall be
allowed to revise the restrictions contained herein to cover the maximum
duration, scope and area permitted by law. Because Executive's services are
unique and because Executive has access to confidential information, the parties
hereto agree that money damages would be an inadequate remedy for any breach of
this Agreement. Therefore, in the event a breach or threatened breach of this
Agreement, the Company or its successors or assigns may, in addition to other
rights and remedies existing in their favor, apply to any court of competent
jurisdiction for specific performance and/or injunctive or other relief in order
to enforce, or prevent any violations of, the provisions hereof (without posting
a bond or other security).

          (d)  Additional Acknowledgments.  Executive acknowledges that the
               --------------------------
provisions of this Section 8 are in consideration of: (i) employment with the
Company, (ii) the issuance of the Executive Stock and (iii) additional good and
valuable consideration as set forth in this Agreement. In addition, Executive
agrees and acknowledges that the restriction contained in Section 7 and this
Section 8 do not preclude Executive from earning a livelihood, nor do they
unreasonably impose limitations on Executive's ability to earn a living. In
addition, Executive agrees and acknowledges that the potential harm to the
Company of the non-enforcement of Section 7 and this Section 8 outweighs any
potential harm to Executive of its enforcement by injunction or otherwise.
Executive acknowledges that he has carefully read this Agreement and has given
careful consideration to the restraints imposed upon Executive by this
Agreement, and is in full accord as to their necessity for the reasonable and
proper protection of confidential and proprietary information of the Company now
existing or to be developed in the future. Executive expressly acknowledges and
agrees that each and every restraint imposed by this Agreement is reasonable
with respect to subject matter, time period and geographical area.

Agreement. In addition, expenses (including reasonable attorneys' fees) incurred
by the Executive in defending any civil, criminal, administrative or
investigative action, suit or proceeding shall be paid by the Company in advance
of the final disposition of such action, suit or proceeding, unless otherwise
determined by the Outside Directors (as defined in that certain Stockholders
Agreement, dated as of March 23, 1999, by and among the Company, the Investors,
the Executive and certain other stockholders), upon receipt of an undertaking by
or on behalf of the Executive to repay such amount if it shall ultimately be
determined that the Executive is not entitled to indemnification by the Company.

          (b)  Transfers in Violation of Agreement.  Any Transfer or attempted
               -----------------------------------
Transfer of any Executive Stock in violation of any provision of this Agreement
shall be void, and the Company shall not record such Transfer on its books or
treat any purported transferee of such Executive Stock as the owner of such
stock for any purpose.

          (c)  Severability.  Whenever possible, each provision of this
               ------------
Agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or any other jurisdiction, but this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

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

          (e)  Counterparts.  This Agreement may be executed in separate

          (f)  Successors and Assigns.  Except as otherwise provided herein,
               ----------------------
this Agreement shall bind and inure to the benefit of and be enforceable by
Executive, the Company, the Investors and their respective successors and
assigns (including subsequent holders of Executive Stock); provided that the
rights and obligations of Executive under this Agreement shall not be assignable
except in connection with a permitted transfer of Executive Stock hereunder.

          (g)  Choice of Law.  The laws of Delaware shall govern all issues
               -------------
concerning the relative rights of the Company and its stockholders and all other
questions concerning the construction, validity and interpretation of this
Agreement, without giving effect to any choice of law or other conflict of law
provision or rule (whether of the State of Delaware or any other

                                      -17-
<PAGE>

jurisdiction) that would cause the application of the laws of any jurisdiction
other than the State of Delaware.

          (h)  Remedies.  Each of the parties to this Agreement (including the
               --------
Investors) will be entitled to enforce its rights under this Agreement
specifically, to recover damages and costs (including attorney's fees) caused by
any breach of any provision of this Agreement and to exercise all other rights
existing in its favor. The parties hereto agree and acknowledge that money
damages may not be an adequate remedy for any breach of the provisions of this
Agreement and that any party may in its sole discretion apply to any court of
law or equity of competent jurisdiction (without posting any bond or deposit)
for specific performance and/or other injunctive relief in order to enforce or
prevent any violations of the provisions of this Agreement.

          (i)  Amendment and Waiver.  The provisions of this Agreement may be
               --------------------
amended and waived only with the prior written consent of the Company, the
Executive and the Majority Holders (as defined in the Purchase Agreement).

               ---------
procure in its own name and for its own benefit life and/or disability insurance
on Executive in any amount or amounts considered available. Executive agrees to
cooperate in any medical or other examination, supply any information, and to
execute and deliver any applications or other instruments in writing as may be
reasonably necessary to obtain and constitute such insurance. Executive hereby
represents that he has no reason to believe that his life is not insurable at
rates now prevailing for healthy men of his age.

          (k)  Business Days.  If any time period for giving notice or taking
               -------------
action hereunder expires on a day which is a Saturday, Sunday or holiday in the
state in which the Company's chief executive office is located, the time period
shall be automatically extended to the business day immediately following such

withhold from any amounts owing from the Company or any of its Subsidiaries to
the Executive any federal, state, local or foreign withholding taxes, excise
taxes, or employment taxes ("Taxes") imposed with respect to the Executive's
                             -----
compensation or other payments from the Company or any of its Subsidiaries or
the Executive's ownership interest in the Company, including, without
limitation, wages, bonuses, dividends, the receipt or exercise of stock options
and/or the receipt or vesting of restricted stock. The Executive shall indemnify
the Company and its Subsidiaries for any amounts paid with respect to any such
Taxes, together with any interest, penalties and related expenses thereto.

          (m)  Termination.  This Agreement (except for the provisions of
               -----------
Section7) shall survive a Separation and shall remain in full force and effect
after such Separation.

          (n)  Generally Accepted Accounting Principles; Adjustments of Numbers.
               ----------------------------------------------------------------
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 generally accepted
accounting principles, consistently applied, except that if because of a change
in generally accepted accounting principles the Company would have to alter a
previously utilized accounting method or policy in order to remain in compliance
with generally accepted accounting principles, 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.

          (o)  Deemed Transfer of Executive Stock.  If the Company (and/or the
               ----------------------------------
Investors and/or any other Person acquiring securities) shall make available, at
the time and place and in the amount and form provided in this Agreement, the
consideration for the Executive Stock to be repurchased in accordance with the
provisions of this Agreement, then from and after such time, the person from
whom such shares are to be repurchased shall no longer have any rights as a
holder of such shares (other than the right to receive payment of such
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.

          (p)  No Pledge or Security Interest.  The purpose of the Company's
               ------------------------------
retention of the Executive's stock certificates and executed stock powers is
solely to facilitate the repurchase provisions set forth in Section 3 herein and
does not constitute a pledge by the Executive of, or the granting of a security
interest in, the underlying stock.

          (q)  Rights Granted to GTCR and its Affiliates.  Any rights granted to
               -----------------------------------------
GTCR and its Affiliates hereunder may also be exercised (in whole or in part) by
its designees (which may be Affiliates).

                                PROMISSORY NOTE
                                ---------------

May 21, 1999                                                          $50,600.00


          Frank Torbey ("Maker") hereby promises to pay to the order of ZEFER
                         -----
Corp. (the "Company"), the principal amount of $50,600.00 together with interest
            -------
thereon calculated from the date hereof in accordance with the provisions of
this Note.

          This Note is the Executive Note referred to in the Senior Management
Agreement, dated as of the date hereof, between the Company and Maker (the
"Management Agreement").  Section 1(a) of the Management Agreement contains
 --------------------
provisions for the issuance of this Note upon the terms and conditions specified
herein.  Capitalized terms used herein and not otherwise defined shall have the
meanings given to them in the Management Agreement.

     1.   Interest. Interest shall accrue on the outstanding principal amount of
          --------
this Note at a rate equal to the lesser of (i) 5% per annum or (ii) the highest
rate permitted by applicable law, compounded annually on each anniversary of the
date hereof.

     2.   Payment on Note.
          ---------------

          (a)  Term.  Subject to Section 2(b) below, the entire principal amount
               ----
of this Note and all accrued interest thereon shall be due and payable on the
fifth anniversary of the date hereof.

          (b)  Mandatory Prepayments.  Notwithstanding anything in Section 2(a)
               ---------------------
to the contrary, Maker shall make the following mandatory prepayments:

               (i)   Upon the purchase of Stock from time to time by the
     Investors pursuant to Section 1B(b) of the Purchase Agreement dated March
     23, 1999 by and among the Company and the Investors, as amended from time
     to time (the "Purchase Agreement"), Maker shall make a payment of principal
                   ------------------
     in an amount equal to the product of (A) $55,000, multiplied by (B) the
                                                       -------------
     quotient of (x) the amount paid to the Company in connection with such
     purchase of Stock by Investors, divided by (y) $100,000,000, plus all
                                     ----------
     accrued interest on such principal amount (or such lesser principal amount
     then outstanding). For purposes hereof, "Stock" shall have the meaning set
                                              -----
     forth in the Purchase Agreement.

               (ii)  In the event Maker receives any net cash proceeds (A) in
     connection with the payment of a dividend or other distribution by the
     Company or (B) relating to any other transaction or series of transactions

     amounts owed pursuant to this Note by applying all of such proceeds first,
                                                                         -----
     to any accrued interest and second, to any principal then outstanding.
                                 ------

     meanings set forth in the Senior Management Agreement.
<PAGE>

time without premium or penalty, prepay all of the outstanding principal amount
of the Note; provided that any prepayment will be accompanied by a payment of
accrued interest on the portion being prepaid.

          (d)  Right of Offset.  Upon an Event of Default (as described in
               ---------------
Section 3 hereof) or the Company's repurchase of Executive Stock pursuant to
Section 3(e) of the Management Agreement, the Company shall be entitled to
offset any amounts owed to the Company by the Maker, now existing or hereinafter
arising, pursuant to this Note against any amounts payable by the Company to the

Company and the Maker.

     3.   Events of Default.
          -----------------

          (a)  Definition.  For purposes of this Note, an Event of Default shall
               ----------
be deemed to have occurred if:

          (i)  Maker fails to pay (A) within 30 days after the date when due,
     the full amount of interest then accrued or (B) when due, the full amount
     of any principal payment; or

          (ii) Maker makes an assignment for the benefit of creditors or admits
     in writing his inability to pay his debts generally as they become due; or
     an order, judgment or decree is entered adjudicating Maker bankrupt or
     insolvent; or any order for relief with respect to Maker is entered 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
<PAGE>

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.

          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.
               105 South Street
               Boston, MA 02111
               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.

     8.   Governing Law.  This Note is made under and governed by the internal
          -------------
law, not the laws of conflicts, of the State of Delaware.

1999 the excess (if any) of the Shares' fair market value on May 21, 1999 over
the purchase price thereof.

                          SENIOR MANAGEMENT AGREEMENT


          This SENIOR MANAGEMENT AGREEMENT (this "Agreement") is made as of
September 13, 1999, between ZEFER Corp., a Delaware corporation (the "Company"),
and Thomas Waite ("Executive").

          The Company and Executive are entering into a stock purchase agreement
(the "Stock Purchase Agreement") pursuant to which Executive will receive, and
the Company will issue, 197,400 shares of the Company's Common Stock, par value
$.01 per share (the "Common Stock"), as partial consideration for the delivery
by Executive of all of Executive's shares of capital stock of Waite & Company,
Inc.  All such 197,400 shares of Common Stock acquired by Executive are referred
to herein as "Executive Stock."  In addition, the Company desires to employ the
Executive and the Executive desires to be employed by the Company.  Certain
definitions are set forth in Section 9 of this Agreement.

          In consideration of the mutual covenants and premises contained herein
and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged by the parties hereto, the parties agree as follows:

                    PROVISIONS RELATING TO EXECUTIVE STOCK

          1.   Purchase and Sale of Executive Stock.
               ------------------------------------

          (a)  In connection with the Stock Purchase Agreement, the Company
will, concurrently with the execution hereof and subject to the terms and
conditions set forth herein, issue to Executive 197,400 shares of Common Stock
at a price of $.38 per share.

          (b)  Within 30 days after the date hereof, Executive will make an
effective election with the Internal Revenue Service under Section 83(b) of the
Internal Revenue Code and the regulations promulgated thereunder in the form of
Exhibit A attached hereto.
- ---------

          (c)  Until the occurrence of a Sale of the Company or a Public
Offering, all certificates evidencing shares of Executive Stock shall be held by
the Company for the benefit of the Executive and the other holder(s) of
Executive Stock.  Upon the occurrence of a Sale of the Company or a Public
Offering, the Company will return the certificates for the Executive Stock to
the record holders thereof.

          (d)  Executive acknowledges and agrees that neither the issuance of
the Executive Stock to Executive nor any provision contained herein shall
entitle Executive to remain in the employment of the Company or any of its
Subsidiaries or affect the right of the Company to
<PAGE>

terminate Executive's employment at any time for any reason, subject, however,
to the terms of this Agreement.

          (e)  Concurrently with the execution of this Agreement, (i) Executive
shall execute in blank ten stock transfer powers in the form of Exhibit B
                                                                ---------
attached hereto (the "Stock Powers") with respect to the Executive 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 Executive
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
Executive's spouse shall execute the consent in the form of Exhibit C attached
                                                            ---------
hereto.

          2.   Vesting of Executive Stock.
               --------------------------

          (a)  All of the shares of Executive Stock acquired hereunder shall be
subject to vesting in the manner specified in this Section  2.  Except as
otherwise provided in Sections 2(b) and 2(c) below, the Executive  Stock will
become vested in accordance with the following schedule (the "Vesting
Schedule"), if as of each such date Executive is still employed by the Company
or any of its Subsidiaries:



                  Date                    Cumulative Percentage of
                  ----                  Executive Stock to be Vested
                                        ----------------------------

             March 31, 2000                       30%
             March 31, 2001                       60%

             March 31, 2003                       86%
             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 Executive is still employed by the Company or any
of its Subsidiaries, the Executive Stock will vest as follows:

               (i)  If the Modification Date is June 30 of any year, then an
additional 25% of the amount of Executive Stock that would have vested pursuant
to the Vesting Schedule on March 31 of the following year will vest on such
Modification Date and an additional 25% of the amount of Executive Stock that
would have vested pursuant to the Vesting Schedule on March 31 of the following
year will vest on September 30 and December 31 of such year and on March 31 of
such following year, and, thereafter, beginning with June 30 of each year, 25%
of the amount of Executive Stock that would have

                                      -2-

<PAGE>

have vested pursuant to the Vesting Schedule on March 31 of each subsequent year
will vest on such June 30 and on the following September 30, December 31 and
March 31, so that the Executive Stock will be 100% vested on March 31, 2004.

          (ii)  If the Modification Date is September 30 of any year, then an
additional 50% of the amount of Executive Stock that would have vested pursuant
to the Vesting Schedule on March 31 of the following year will vest on such
Modification Date and an additional 25% of the amount of Executive Stock that
would have vested pursuant to the Vesting Schedule on March 31 of the following
year will vest on December 31 of such year and on March 31 of such following
year, and, thereafter, beginning with June 30 of each year, 25% of the amount of
Executive Stock that would have vested pursuant to the Vesting Schedule on March
31 of each subsequent year will vest on such June 30 and on the following
September 30, December 31 and March 31, so that the Executive Stock will be 100%
vested on March 31, 2004.

          (iii) If the Modification Date is December 31 of any year, then an
additional 75% of the amount of Executive Stock that would have vested pursuant
to the Vesting Schedule on March 31 of the following year will vest on such
Modification Date and an additional 25% of the amount of Executive Stock that
would have vested pursuant to the Vesting Schedule on March 31 of the following
year will vest on such March 31, and, thereafter, beginning with June 30 of each
year, 25% of the amount of Executive Stock that would have vested pursuant to
the Vesting Schedule on March 31 of each subsequent year will vest on such June
30 and on the following September 30, December 31 and March 31, so that the
Executive Stock will be 100% vested on March 31, 2004.

          (iv)  If the Modification Date is March 31 of any year, then beginning
with June 30 of such year and each subsequent year, 25% of the amount of
Executive Stock that would have vested pursuant to the Vesting Schedule on March
31 of each following year will vest on such June 30 and on the following
September 30, December 31 and March 31, so that the Executive Stock will be 100%
vested on March 31, 2004.

     (c)  If, at any time, Executive's employment is terminated by the Company
without Cause or Executive terminates his employment with the Company for Good
Reason, all shares of Executive Stock which have not yet vested shall
automatically vest immediately prior to the termination.

     (d)  Shares of Executive Stock which have become vested are referred to
herein as "Vested Shares" and all other shares of Executive Stock are referred
to herein as "Unvested Shares."

                                      -3-
<PAGE>

          3.  Repurchase Option.
              -----------------

          (a)  In the event Executive is terminated for Cause or resigns without
Good Reason (the "Triggering Event"), the Unvested Shares of Executive Stock
(whether held by Executive or one or more of Executive'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 Triggering Event, the purchase price for each
Unvested Share of Executive Stock repurchased pursuant to the Repurchase Option
will be Executive's Original Cost for such Unvested Share.

          (c)  The Company may elect to purchase all or any portion of the
Unvested Shares by delivering written notice (the "Repurchase Notice") to the
holder or holders of the Executive Stock within 120 days after the Triggering
Event.  The Repurchase Notice will set forth the number of Unvested 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 Unvested Shares held by Executive at the time of delivery of
the Repurchase Notice.  If the number of Unvested Shares then held by Executive
is less than the total number of Unvested Shares which the Company has elected
to purchase, the Company shall purchase the remaining shares elected to be
purchased from the other holder(s) of Unvested Shares under this Agreement, pro
rata according to the number of Unvested Shares 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 to be
repurchased hereunder will be allocated among Executive and the other holders of
Unvested Shares (if any) pro rata according to the number of Unvested Shares to
be purchased from such person.

          (d)  If for any reason the Company does not elect to purchase all of
the Unvested Shares pursuant to the Repurchase Option, all other 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 Triggering Event and the Investors
shall be entitled to exercise the Repurchase Option for all or any portion of
the Unvested Shares 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 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.

                                      -4-
<PAGE>

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
Unvested Shares as to the 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 Unvested Shares, 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 to be repurchased hereunder shall be allocated among the
Company, Senior Management and the Investors pro rata according to the number of
Unvested Shares to be purchased by each of them.

          (e)  The closing of the purchase of the Unvested Shares 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 Unvested Shares
to be repurchased by it pursuant to the Repurchase Option with a check or wire
transfer of funds in an amount equal to the Executive's Original Cost.
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 Executive to the Company.
Each Senior Manager and each Investor will pay for the Unvested Shares 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 Unvested Shares.

          (f)  Notwithstanding anything to the contrary contained in this
Agreement, all repurchases of Unvested Shares 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 Unvested Shares hereunder which
the Company is otherwise entitled or required to make, the Company shall make
such repurchases as soon as it is permitted to do so under such restrictions.

          4.   Restrictions on Transfer of Executive Stock.
               -------------------------------------------

          (a)  Transfer of Executive Stock.  The holder of Executive Stock shall
               ---------------------------
not Transfer any interest in any shares of Executive Stock, except pursuant to
(i) the provisions of Section 3  hereof, (ii) the provisions of Section 4 of the
Stockholders Agreement (a "Participating Sale"), (iii) an Approved Sale (as
defined in Section 5 of the Stockholders Agreement), or (iv) the provisions of
Section 4(b) below.

          (b)  Certain Permitted Transfers.  The restrictions in this Section 4
               ---------------------------
will not apply with respect to any Transfer of Executive Stock if made (i)
pursuant to applicable laws of descent

                                      -5-
<PAGE>

and distribution or to such Person's legal guardian in the case of any mental
incapacity or among such Person's Family Group, or (ii) at a time when the
Common Stock of the Company has been trading for at least 45 consecutive days,
or (iii) at such time as the Investors sell shares of Common Stock in a Public
Sale or (iv) pursuant to the Registration Agreement dated March 23, 1999 (the
"Registration Agreement") among the Company (as successor to ZC Acquisition
Corp.), the Investors and certain other stockholders of the Company, to which
Executive, as of the date hereof, is a party; provided, however, that Executive
                                              --------  -------
acknowledges and agrees that at the time of a Public Offering, Executive will be
subject to a lockup agreement, as contemplated by Section 3(a) of the
Registration Agreement, unless the underwriters managing such Public Offering
otherwise agree. Notwithstanding anything in this Section 4 to the contrary, the
restrictions contained in this Section 4 will continue to be applicable to the
Executive Stock after any Transfer of the type referred to in clause (i) and the
transferees of such Executive Stock will agree in writing to be bound by the
provisions of this Agreement. Any transferee of Executive Stock pursuant to a
transfer in accordance with the provisions of this Section 4(b)(i) is herein
referred to as a "Permitted Transferee." Upon the transfer of Executive Stock
pursuant to this Section 4(b), the transferring holder of Executive Stock will
deliver a written notice (a "Transfer Notice") to the Company. In the case of a
Transfer pursuant to clause (i) hereof, the Transfer Notice will disclose in
reasonable detail the identity of the Permitted Transferee(s).

          (c)  Termination of Restrictions.  The restrictions set forth in this
               ---------------------------
Section 4 will continue with respect to each share of Executive Stock until the
earlier of (i) the date on which such share of Executive Stock has been
transferred in a Public Sale permitted by this Section 4, or (ii) the
consummation of an Approved Sale.

          5.   Additional Restrictions on Transfer of Executive Stock.
               ------------------------------------------------------

          (a)  Legend.  The certificates representing the Executive Stock will
               ------
bear a legend in substantially the following form:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE
     ORIGINALLY ISSUED ON [DATE], HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"),
     AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF
     AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR AN
     EXEMPTION FROM REGISTRATION THEREUNDER.  THE SECURITIES
     REPRESENTED BY THIS CERTIFICATE ARE ALSO SUBJECT TO ADDITIONAL
     RESTRICTIONS ON TRANSFER, CERTAIN REPURCHASE OPTIONS AND
     CERTAIN OTHER AGREEMENTS SET FORTH IN A SENIOR MANAGEMENT
     AGREEMENT BETWEEN THE COMPANY AND AN EXECUTIVE OF THE COMPANY
     DATED [DATE]. A COPY OF SUCH AGREEMENT MAY BE OBTAINED BY THE
     HOLDER HEREOF AT THE COMPANY'S PRINCIPAL PLACE OF "BUSINESS
     WITHOUT CHARGE."

                                      -6-
<PAGE>

          (b)  Opinion of Counsel.  No holder of Executive Stock may sell,
               ------------------
transfer or dispose of any Executive Stock (except pursuant to an effective
registration statement under the Securities Act) without first delivering to the
Company 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 Executive Stock delivers to the
Company an opinion of counsel that no subsequent transfer of such Executive
Stock shall require registration under the Securities Act, the Company shall
promptly upon such contemplated transfer deliver new certificates for such
Executive 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 Executive 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.

                       PROVISIONS RELATING TO EMPLOYMENT

          6.  Employment.  The Company agrees to employ Executive and Executive
              ----------

competency and global strategic marketing activities and shall have the normal
duties, responsibilities and authority of such office subject to the power of
the President and Chief Executive Officer of the Company (the "President") to
expand or limit such duties, responsibilities and authority.  Executive shall
report to the President and Executive shall devote his best efforts and his full
business time and attention to the business and affairs of the Company and its
Subsidiaries; provided, however, that Executive may, to the extent not
              --------  -------

write books, articles and other publications for publication in Executive's name
as author, serve on industry conference panels and engage in public speaking
and, subject to the reasonable approval of the Board, serve on boards of

made available to the Company's senior management. Executive will be eligible
for other bonuses, stock options and other benefits at the same level that is
generally made available to the Company's senior management, provided that the
                                                             --------
final determination of the amount of any award of bonuses, stock options and
other forms of compensation shall be made by the compensation committee of the
Board, and provided, further, that the Executive Stock (and any other capital
           --------  -------
stock of the Company acquired by Executive other than pursuant to such an award)
will not be considered in any determination of Executive's eligibility for any
such award.

          (c)   Events of Separation.  The Employment Period will continue until
                --------------------
Executive's  resignation, disability (as determined by the President in his good
faith judgment) or death or until the President decides to terminate Executive's
employment.

          (d)   Separation Without Cause; Resignation for Good Reason. In the
                -----------------------------------------------------
event that (i) the Company terminates the Executive's employment without Cause
or (ii) the Executive resigns from his position with the Company for Good
Reason, then the Executive shall be entitled to the following:

          (i)   the Company shall pay to the Executive, in a lump sum within 15
days after such termination or resignation, an amount equal to the sum of
(A) any unpaid base salary owed to the Executive for services performed
prior to such termination, plus (B) the amount of any compensation
previously deferred by the Executive (together with any accrued interest or
earnings thereon) and any accrued vacation pay, in each case to the extent
not previously paid (the obligations set forth in clauses (A) and (B) are
collectively referred to herein as the "Accrued Obligations");

          (ii)  the Company shall pay each month to the Executive, beginning on
the date of the first normal executive payroll of the Company that occurs more
than 30 days after such termination or resignation, an amount equal to one-
twelfth (1/12) of the Executive's Annual Base Salary as of the date immediately
before such termination or resignation; provided, however, that such payments
                                        --------  -------
shall immediately cease upon the earliest to occur of (x) the Executive's death
and (y) the date on which one-half (1/2) of the Executive's Annual Base Salary
as of the date immediately before such termination or resignation is paid to the
Executive. Notwithstanding anything in this Section 6(d) to the contrary, in the
event that the Executive becomes employed with another employer, then the
payments to be made by the Company pursuant to this Section 6(d)(ii) shall be
reduced (on a dollar for dollar basis) in an amount equal to the cash
compensation received by Executive from such employer; and

          (iii) the Company shall continue to provide medical insurance benefits
to the Executive and to the Executive's family at least equal to those medical
insurance benefits that would have been provided to them in the absence of such
termination or resignation;

                                      -8-
<PAGE>

provided, however, that such payments shall immediately cease upon the earliest
- --------  -------
to occur of (x) the Executive's death and (y) the six month anniversary of such
termination or resignation. Notwithstanding anything in this Section 6(d) to the
contrary, in the event that the Executive becomes employed with another employer
and is eligible for medical insurance benefits under another employer-provided
plan, then the medical insurance benefits to be provided by the Company pursuant
to this Section 6(d)(iii) shall be reduced to the extent that the Executive and
his family are eligible to receive medical insurance benefits under such other
employer-provided plan.

          (e)  Other Separations.  In the event of a Separation other than a
               -----------------
termination by the Company without Cause or a resignation by the Executive for
Good Reason, the Company shall pay to the Executive (or his estate, if
applicable), in a lump sum in cash within 15 days after such Separation, an
amount equal to any Accrued Obligations.

          7.   Confidential Information.  Executive acknowledges that the
               ------------------------
information and data obtained by him during the course of his performance under
this Agreement concerning the business and affairs of the Company and its
affiliates are the property of the Company, including information concerning
acquisition opportunities in or reasonably related to the Company's business or
industry of which Executive becomes aware during the Employment Period.
Therefore, Executive agrees that he will not disclose to any unauthorized person
or use for his own account any of such information or data without the Company's
written consent, unless and to the extent that the aforementioned matters become
generally known to and available for use by the public other than as a result of
Executive's acts or omissions to act. Executive agrees to deliver to the Company
at a Separation, or at any other time the Company may request in writing, all
memoranda, notes, plans, records, reports and other documents (and copies
thereof) relating to the business of the Company and its affiliates (including,
without limitation, all acquisition prospects, lists and contact information)
which he may then possess or have under his control.

          8.   Noncompetition and Nonsolicitation.    Executive acknowledges
               ----------------------------------
that in the course of his employment with the Company he will become familiar
with the Company's and its Subsidiaries' trade secrets and with other
confidential information concerning the Company and such Subsidiaries and that
his services will be of special, unique and extraordinary value to the Company.
Therefore, Executive agrees that:

          (a)  Noncompetition.  During the Employment Period and for a period of
               --------------
six months thereafter (the "Noncompete Period"), Executive shall not, within the
United States, directly or indirectly own, manage, control, participate in,
consult with, render services for, or in any manner engage in any business
competing with the businesses of the Company or its Subsidiaries or any business
in which the Company or any of its Subsidiaries has requested and received
information relating to the acquisition of such business by the Company and the
Subsidiaries prior to the Separation; provided that passive ownership of less
                                      --------
than 5% of the outstanding stock of any publicly-traded corporation shall not,
in and of itself, be deemed to violate this Section 8(a).

                                      -9-
<PAGE>

          (b)  Nonsolicitation.  During the Noncompete Period, Executive shall
               ---------------
not directly or indirectly through another entity (i) induce or attempt to
induce any employee of the Company or its Subsidiaries to leave the employ of
the Company or such Subsidiary, or in any way interfere with the relationship
between the Company and any Subsidiary and any employee thereof, (ii) hire any
person who was an employee of the Company or any Subsidiary within 180 days
prior to the time such employee was hired by the Executive, (iii) induce or
attempt to induce any customer, supplier, licensee or other business relation of
the Company or any Subsidiary to cease doing business with the Company or such
Subsidiary or in any way interfere with the relationship between any such
customer, supplier, licensee or business relation and the Company or any
Subsidiary or (iv) directly or indirectly acquire or attempt to acquire an
interest in any business relating to the business of the Company or any
Subsidiary and with which, to the Executive's knowledge, the Company or any
Subsidiary has entertained discussions or has requested and received information
relating to the acquisition of such business by the Company or any Subsidiary in
the two-year period immediately preceding a Separation.

          (c)  Enforcement.  If, at the time of enforcement of Section 7 or this
               -----------
Section 8, a court holds that the restrictions stated herein are unreasonable
under circumstances then existing, the parties hereto agree that the maximum
duration, scope or geographical area reasonable under such circumstances shall
be substituted for the stated period, scope or area and that the court shall be
allowed to revise the restrictions contained herein to cover the maximum
duration, scope and area permitted by law.  Because Executive's services are
unique and because Executive has access to confidential information, the parties
hereto agree that money damages would be an inadequate remedy for any breach of
this Agreement.  Therefore, in the event a breach or threatened breach of this
Agreement, the Company or its successors or assigns may, in addition to other
rights and remedies existing in their favor, apply to any court of competent
jurisdiction for specific performance and/or injunctive or other relief in order
to enforce, or prevent any violations of, the provisions hereof (without posting
a bond or other security).

          (d)  Additional Acknowledgments.  Executive acknowledges that the
               --------------------------
provisions of this Section 8 are in consideration of employment with the
Company.  In addition, Executive agrees and acknowledges that the restrictions
contained in Section 7 and this Section 8 do not preclude Executive from earning
a livelihood, nor do they unreasonably impose limitations on Executive's ability
to earn a living.  In addition, Executive agrees and acknowledges that the
potential harm to the Company of the non-enforcement of Section 7 and this
Section 8 outweighs any potential harm to Executive of enforcement by injunction
or otherwise.  Executive acknowledges that he has carefully read this Agreement
and has given careful consideration to the restraints imposed upon Executive by
this Agreement, and is in full accord as to their necessity for the reasonable
and proper protection of confidential and proprietary information of the Company
now existing or to be developed in the future.  Executive expressly acknowledges
and agrees that each and every restraint imposed by this Agreement is reasonable
with respect to subject matter, time period and geographical area.

has given Executive reasonable notice that the Executive has engaged in conduct

misconduct to the reasonable satisfaction of the Company.

          "Executive's Family Group" means Executive's spouse and descendants
           ------------------------

bid and lowest asked prices on all such exchanges at the end of such day, or, if
on any day such Executive Stock is not so listed, the average of the

names of four nationally recognized investment banking firms, and each party
shall be entitled to strike two names from the other party's list of firms, and
the appraiser shall be selected by lot from the remaining four investment
banking firms. The expenses of such appraiser shall be borne by the party whose
Fair Market Value determination, as such determination may have been modified
during the 30-day negotiation period following delivery of the Repurchase Notice
or Supplemental Repurchase Notice, as applicable, 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

the parties. The determination of such appraiser as to Fair Market Value shall
be final and binding upon all parties.

          (c)  Severability.  Whenever possible, each provision of this

Agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or any other jurisdiction, but this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

               ------------------
referred to herein and other documents of even date herewith embody the complete

because of a change in generally accepted accounting principles the Company
would have to alter a previously utilized accounting method or policy in order
to remain in compliance with generally accepted accounting principles, 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.

               ----------------------------------
Investors and/or any other Person acquiring securities) shall make available, at
the time and place and in the amount and form provided in this Agreement, the
consideration for the Executive Stock to be repurchased in accordance with the
provisions of this Agreement, then from and after such time, the person from
whom such shares are to be repurchased shall no longer have any rights as a
holder of such shares (other than the right to receive payment of such
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.

          (p)  No Pledge or Security Interest.  The purpose of the Company's
               ------------------------------

interest in, the underlying stock.

           3.1.2.    The Lender shall, and is hereby authorized by the Borrower
to, endorse on the schedules annexed to the Note an appropriate notation
evidencing the date and amount of each Loan made by the Lender as well as the

<PAGE>

     3.3.  Interest on the Loans.
           ---------------------

           3.3.1.   The Loans shall bear interest at a rate equal to 12% per
annum on the unpaid principal amount thereof (including Capitalized Interest, as
hereinafter defined) from and including the Closing Date until the principal
amount shall be paid in full, such interest to be payable in cash in the manner
specified in Section 3.7; provided that the Lender and the Board may agree that,
                          --------
for any Interest Period, interest on all or any portion of the Loans may be paid
by capitalizing such interest as additional Loans on the applicable Interest
Payment Date ("Capitalized Interest"), and any interest that is to be
               --------------------
capitalized shall be calculated at a rate that is equal to 14%.  Notwithstanding
the foregoing, the interest rate on any overdue payment of principal, and to the
extent permitted by law, on any overdue installments of interest that are not
capitalized as described above, shall be 14%.

           3.3.2.   Interest shall be payable with respect to the Loans, in
arrears, on the last day of each Interest Period, upon any prepayment of the
Loans (to the extent of accrued interest on the principal amount, including
Capitalized Interest, of the Loans so prepaid) and at maturity of the Loans.
"Interest Period" means (i) initially, the period commencing on the Closing Date
 ---------------
(with respect to the Initial Loan) or on the date any subsequent Loan is made
(with respect to subsequent Loans) and ending on the next succeeding Interest
Payment Date (as hereinafter defined) and (ii) thereafter, each quarterly period
ending on March 31, June 30, September 30 or December 31, as applicable (each
such date, an "Interest Payment Date"); provided that no Interest Period shall
               ---------------------    --------
extend beyond the Maturity Date. Notwithstanding the foregoing, if the aggregate
amount of accrued and unpaid interest (including all Capitalized Interest) and
all unpaid original issue discount on any Interest Payment Date occurring after
the fifth anniversary of the Closing shall exceed an amount equal to the product
of (x) the issue price (as defined in Code Sections 1273(b) and 1274(a)) of the
Note and (y) the yield to maturity (as defined in Code Section 163(i)) of the
Loans (such product being the "Maximum Accrual"), all accrued and unpaid
                               ---------------
interest on the Loans in excess of an amount equal to the Maximum Accrual shall
be paid by the Borrower to the holders of the Note on such Interest Payment
Date. Any accrued interest which for any reason has not theretofore been paid
shall be paid in full on the date on which the final principal payment on the
Loans is made.

           3.3.3.    Interest on the Loans shall be computed on the basis of a
360-day year of twelve 30-day months for the actual number of days elapsed
during which it accrues. In computing such interest, the date or dates of the
making of the Loans shall be included and the date of payment shall be excluded.
If a Loan is repaid on the same day that it is made, one (1) day's interest
shall be charged.

           3.3.4.    Under no circumstances will the rate of interest chargeable
be in excess of the maximum amount permitted by law. If excess interest is
charged and paid in error, then the excess amount will be promptly refunded.

     3.4.  Voluntary Prepayments. Subject to the terms and conditions of the
           ---------------------
Loan Documents, the Loans may be prepaid without penalty, at the Borrower's
option, at any time and from time to time, in whole or in part, upon not less
than one (1) Business Day prior written notice to the Lender; provided that such
                                                              --------
prepayment shall be (i) in a minimum aggregate amount of $250,000 (or such
lesser amount then outstanding under the Loans) or (ii) in an integral multiple
of $250,000.

          3.5.1.  Asset Dispositions; Sale of Subsidiary Stock. Within thirty
                  --------------------------------------------
(30) days following receipt by the Borrower or any of its Subsidiaries of the
Net Proceeds of any Asset Disposition, which Net Proceeds exceed $100,000 for
any transaction or series of transactions, the Borrower shall prepay the Loans
in an amount equal to all such Net Proceeds. Notwithstanding the foregoing, the
Borrower may retain the Net Proceeds of Asset Dispositions to the extent that
such Net Proceeds are used either to replace the assets so disposed of or to
purchase other capital assets used in the Borrower's business; provided that, if
                                                               --------
the Borrower shall not have replaced such assets or purchased other capital
assets with such Net Proceeds within 365 days following such disposition, such
Net Proceeds will be applied to the payment of the Loans as provided in the
immediately preceding sentence. Payments pursuant to this subsection 3.5.1 shall
be applied in accordance with Section 3.6.

          3.5.2.  Change of Control. Upon the occurrence of a Change of Control,
                  -----------------
the Borrower shall prepay in full all unpaid principal and interest (including
Capitalized Interest) outstanding on the Loans.

                  -----------------------
public offering of the Borrower's equity securities, the Borrower shall prepay
in full all unpaid principal and interest (including Capitalized Interest)
outstanding on the Loans.

          3.5.4.  Notice. The Borrower shall notify the Lender of any event
                  ------
which could reasonably be expected to give rise to any prepayment to be made
pursuant to subsections 3.5.1 through 3.5.3.

          3.5.5.  Calculation of Net Proceeds Amounts.  Concurrently with any
                  -----------------------------------
prepayment of the Loans pursuant to subsections 3.5.1 through 3.5.3, the
Borrower shall deliver to the Lender a Borrower's Certificate demonstrating the
calculation of the amount of the proceeds that gave rise to such prepayment.

     3.6. Application of Prepayments.  All prepayments (whether voluntary or
          --------------------------
mandatory) shall include, notwithstanding subsection 3.3.2 above, the payment in
cash of accrued and unpaid interest on the principal amount (including
Capitalized Interest) of the Loans so prepaid and shall be applied first to
payment of principal before application to accrued interest thereon.

     3.7. Manner and Time of Payment.
          --------------------------

          3.7.1.  All payments by the Borrower under the Note of principal,

under the Note.

available to the Lender under the Loan Documents and applicable laws.

Loans to the Borrower hereunder, the Borrower represents and warrants to the
Lender that the following statements are and, after giving effect to the
transactions contemplated by this Agreement or any of the Loan Documents, will
be true, correct and complete:

     4.1.  Full Disclosure.  No statement or information contained in this

Agreement, any financial statements delivered hereunder, the other Loan

the Lender or any other holder of the Note, by or on behalf of the Borrower for
use in connection with the transactions contemplated by the Loan Documents

materials referenced above are based on good faith estimates and assumptions
believed by management of the Borrower to be reasonable at the time made, it

period or periods covered by such financial information may differ from the
projected results set forth therein by a material amount.

           --------------------------
no events or changes in facts or circumstances affecting the Borrower or any of

written consent of the Lender.

            5.2.2.  Each Grantor assumes full responsibility for taking any and
all steps to preserve its rights with respect to the Collateral against all
prior parties. The Lender shall be deemed to have exercised reasonable care in
the preservation and custody of the portion of the Collateral as may be in the

reasonably request in writing; provided that such requested action shall not, in
                               --------

that such written request is received by the Lender in sufficient time to permit
the Lender to take the requested action. In the absence of such written request,

portion thereof are outstanding and unpaid or the Lender may be obligated to
advance funds to the Borrower under

advisable from time to time to perfect and continue perfected such security
interests. Each Grantor shall do all such other acts and things and shall
execute and deliver all such other instruments and documents (including, without
limitation, further security agreements, pledge agreements, pledges,
endorsements, assignments and notices) as the Lender may deem necessary or
advisable from time to time to perfect and preserve the priority of the Lender's
security interest in the Collateral, as a perfected security interest in the
Collateral, prior to the rights of any other secured party or lien creditor,
except with respect to Permitted Encumbrances which are accorded priority by
statute. No Grantor will create, permit or suffer to exist, and each Grantor
will defend the Collateral against and take such other actions as is necessary
to remove, any Lien on the Collateral except the Permitted Encumbrances, and
will defend the right, title and interest of the Lender in and to the Collateral

Proceeds arising from all Receivables owned by or in the possession of any
Grantor, upon written notice to such Grantor, and to apply such Proceeds to the
payment of the Secured Obligations as determined in the Lender's sole
discretion. At any such time and upon such written notice, the Lender may (i)
notify account debtors and contract obligors of the grant to and creation in
favor of the Lender of the security interest in the Receivables and the Proceeds
thereof under this Agreement, (ii) direct such account debtors and contract
obligors to make any payments from time to time due in respect of any such
Receivables directly to the Lender at such places as it directs and (iii) assume
entire control over all of the Proceeds of such Receivables. Each Grantor, upon
receipt of written notice from the Lender of the revocation of such Grantor's
right of collection, shall promptly remit directly to the Lender all Proceeds of
Receivables then or subsequently in its possession, and any collections and
receipts with respect to such Proceeds and Receivables shall not be commingled

Event of Default, any Grantor may in the ordinary course of business allow
adjustments to the original amount owing on a Receivable in accordance with such
Grantor's customary and commercially reasonable credit policies and collection
practices in effect from time to time. Without the prior written consent of the
Lender in each case, no Grantor shall make any sale to any customer on a bill
and hold, guaranteed sale, sale or return, sale on approval, consignment or any
other repurchase or return basis, or re-date any invoice or make sales on
extended dating beyond that customary in its industry, or otherwise change the
terms of sale customarily offered to its customers. If any Grantor becomes aware
of any event or circumstance materially detrimental to any account debtor's
credit, it shall promptly advise the Lender thereof, and each Grantor shall
promptly notify the Lender of any change in its credit policies and collection
practices and shall not make any such change which the Lender determines in its

request, instruct them to hold all such Inventory and Equipment for the Lender's
account and subject to the Lender's instructions. If more than $25,000 in fair
market value of Inventory and Equipment is held by any such bailee, the Grantor

insurers as is acceptable to the Lender or as otherwise required by the Loan
Agreement; provided that the Grantors shall maintain insurance with respect to
           --------
the Collateral in an aggregate amount at least equal to the lesser of (i) the
outstanding amount of the Secured Obligations and (ii) the full insurable value
of the Collateral. Each such insurance policy shall be in form and substance
satisfactory to the Lender and shall

                                      -11-
<PAGE>

(i) contain a loss payable clause and a lenders' loss payable endorsement in
favor of the Lender as its interest may appear, (ii) provide that at least
thirty (30) days prior written notice of any material change to or any
cancellation or lapse of such policy must be given to the Lender by the insurer,
(iii) provide that no act or default by any Grantor under such policy shall
impair the Lender's right of recovery thereunder and (iv) provide that the
insurer shall, as against the Lender, waive any rights of subrogation to the
extent that the named insured has waived such rights (and each Grantor hereby
irrevocably and unconditionally waives any right of subrogation against the
Lender). Each Grantor shall deliver to the Lender all original insurance
policies, or certificated copies thereof, and evidence of payment of all
premiums with respect thereto.

           5.6.3.   If any Grantor fails to obtain and keep in full force and
effect the insurance coverage required hereunder or fails to pay the premiums
therefor when due, the Lender may (but shall not be obligated to) do so for the
account of such Grantor (without waiving or releasing any obligation or default
of such Grantor hereunder), and the cost thereof shall be added to the Secured
Obligations and shall be payable upon demand with interest accruing thereon at
the highest rate of interest accruing on the Loans under the Loan Agreement.

           5.6.4.   Each Grantor hereby assigns and sets over unto the Lender
all moneys which may become payable on account of such insurance (including,
without limitation, any returned or unearned premiums which may be due upon
cancellation of any such insurance which is not promptly replaced by comparable
insurance) and directs the insurers to pay the Lender any amount so due;
provided that so long as no Event of Default shall have occurred and be
continuing or shall exist, any such moneys not exceeding $500,000 in the
aggregate may be used by such Grantor to substantially repair or to replace with
substantially comparable Collateral the particular lost, damaged or destroyed
Collateral within one-hundred eighty (180) days of receipt of such insurance
proceeds.

     5.7.  Records.  Each Grantor shall at all times maintain accurate and
           -------
complete records with respect to each item and category of the Collateral
(including, without limitation, a record of all Proceeds) and shall furnish
copies of such records to the Lender with reasonable promptness from time to
time upon the Lender's request.

     5.8.  Taxes and Charges.  Each Grantor shall, jointly or severally, pay and
           -----------------
discharge all taxes, levies and other impositions levied on any Collateral owned
by it or in its possession (except to the extent that such taxes, levies and
other impositions shall not then be due or shall be contested in good faith by
appropriate proceedings diligently conducted; provided that such reserves and
                                              --------
other provisions as may be required by generally accepted accounting principles
have been duly made and recorded on the appropriate Grantor's financial
records).  If any Grantor shall fail to do so, the Lender may (but shall not be
obligated to) pay such taxes, levies or impositions for the account of such
Grantor (without waiving or releasing any obligation or default by such Grantor
hereunder), and the amount thereof shall be added to the Secured Obligations and
shall be payable upon demand with interest accruing thereon at the highest rate
of interest accruing on the Loans under the Loan Agreement.

     5.9.  Inspection.  The Lender and its officers, employees and agents shall
           ----------
have the right at all reasonable times to inspect the Collateral and to examine
and make extracts from any books and records

                                      -12-
<PAGE>

of each Grantor pertaining to the Collateral owned by it or in its possession.
The Lender may at any time, without notice to a Grantor, verify with any account
debtor of such Grantor the status of any account payable by such account debtor.
Each Grantor from time to time shall execute and deliver such instruments and
take all such action as the Lender may reasonably request in order to effectuate
the provisions of this Section 5.9.

     5.10.  Federal Claims.  Each Grantor shall notify the Lender of any
            --------------
Collateral which constitutes a claim against the United States government or any
instrumentality or agency thereof, the assignment of which claim is governed by
federal law. Upon the request of the Lender, any such Grantor shall at its
expense take all actions required to comply, to the Lender's satisfaction, with
the Assignment of Claims Act of 1940, as amended, or any similar applicable law,
with respect to any such Collateral.

     5.11.  Name Change; Location.
            ---------------------

            5.11.1.  If any Grantor desires to establish a new location for its
chief executive office or a new location for any offices, plants or facilities
where any Collateral or any books or records relating to the Collateral may be
kept or to establish a new name in which it may do business, it shall first,
with respect to each such new location or name, (i) give the Lender at least
thirty (30) days prior written notice of its intention to do so and provide the
Lender with such information in connection therewith as the Lender may
reasonably request and (ii) if financing statements are on file with respect to
any Collateral, take such action, upon request of the Lender, as may be
necessary to maintain at all times the perfection and priority of the security
interests in the Collateral granted to the Lender hereunder.

            5.11.2.  All of the Inventory of each Grantor shall be kept at all
times at the locations specified on Schedule I hereto and at no other locations,
                                    ----------
except upon compliance with the requirements of subsection 5.11.1 of this
Agreement and except for Inventory in transit which is being sold in the
ordinary course of business.

            5.11.3.  All of the Equipment and Fixtures of each Grantor shall be
kept and maintained at all times at the locations specified in Schedule I and at
                                                               ----------
no other locations, except (i) upon compliance with the requirements of
subsection 5.11.1 of this Agreement or (ii) as sold, transferred or otherwise
disposed of as permitted by the terms of the Loan Agreement or this Agreement.

     5.12.  Intellectual Property. If any Grantor shall (i) obtain rights to any
            ---------------------
new registered Copyrights, Patents or Trademarks, or (ii) become entitled to the
benefit of any registered Copyrights or any Patents or Trademarks or any
improvement on any Patent, the provisions of this Agreement shall automatically
apply thereto and such Grantor shall give to the Lender prompt written notice
thereof.  Each Grantor authorizes the Lender to modify this Agreement by
amending Schedule II hereto to include any such registered Copyrights or any
         -----------                            ----------
such Patents and Trademarks.  Each Grantor shall have the duty (i) to prosecute
diligently any patent, trademark, or service mark applications pending as of the
date hereof or hereafter, if such Grantor deems it in its reasonable business
judgment to be necessary or appropriate, (ii) to make application on unpatented
but patentable inventions and on trademarks, copyrights and service marks, as
appropriate, if such Grantor deems it in its reasonable business judgment to be
necessary or

                                      -13-
<PAGE>

appropriate, to preserve and maintain all rights in the Copyrights, Patents and
Trademarks, to the extent material to the operations of the business of such
Grantor and (iii) to ensure that the Copyrights, Patents and Trademarks are and
remain enforceable, to the extent material to the operations of the business of
such Grantor. Any expenses incurred in connection with any Grantor's obligations
under this Section 5.12 shall be borne by the Grantors jointly and severally. No
Grantor shall abandon any right to file a material patent, trademark, or service
mark application, or abandon any material pending patent application, or any
other Copyright, Patent or Trademark without the written consent of the Lender,
which consent shall not be unreasonably withheld. On and after the date of this
Agreement, at the request of the Lender, each Grantor shall execute and deliver
to the Lender a Copyright security agreement, Patent security agreement and a
Trademark security agreement, and all other documents, instruments, and other
items as may be necessary for the Lender to perfect a first priority security
interest (subject only to Permitted Encumbrances which are accorded priority by
statute) in Copyrights, Patents, Trademarks, or any other type or kind of
Intellectual Property owned by such Grantor.

     5.13.  Investment Property.  Each Debtor will take any and all actions
            -------------------
required or requested by the Lender, from time to time, to (i) cause the Lender
to obtain exclusive control of any Investment Property owned by such Grantor in
a manner acceptable to the Lender and (ii) obtain from any issuers of Investment
Property and such other Persons, for the benefit of the Lender, written
confirmation of the Lender's control over such Investment Property. For purposes
of this Section 5.13, the Lender shall have exclusive control of Investment
Property if: (i) such Investment Property consists of certificated securities
and a Grantor delivers such certificated securities to the Lender (with
appropriate endorsements if such certificated securities are in registered
form); (ii) such Investment Property consists of uncertificated securities and
either (a) a Grantor delivers such uncertificated securities to the Lender or
(b) the issuer thereof agrees, pursuant to documentation in form and substance
satisfactory to the Lender, that it will comply with instructions originated by
the Lender without further consent by such Grantor; and (iii) such Investment
Property consists of security entitlements and either (a) the Lender becomes the
entitlement holder thereof or (b) the appropriate securities intermediary
agrees, pursuant to documentation in form and substance satisfactory to the
Lender, that it will comply with entitlement orders originated by the Lender
without further consent by such Grantor.

     5.14.  License of General Intangibles.  For purposes of enabling the Lender
            ------------------------------
to exercise its rights and remedies hereunder, at the Lender's request following
the occurrence of an Event of Default, each Grantor hereby grants to the Lender
an irrevocable, nonexclusive license (exercisable without payment of any royalty
or other compensation to such Grantor) to use, assign, license or sublicense any
of such Grantor's General Intangibles, wherever the same may be located,
including in such license reasonable access to all media in which any of the
General Intangibles may be recorded or stored and to all computer programs used
for the compilation or printout thereof; provided that the Lender shall comply
                                         --------
with all reasonable quality control standards and trademark use requirements of
such Grantor.  No agreements hereafter acquired or agreed to or entered into by
any Grantor shall prohibit, restrict or impair the rights granted to the Lender
hereunder. Notwithstanding the foregoing, the Lender shall have no obligations
or liabilities regarding any or all of the General Intangibles of any Grantor by
reason of, or arising out of, this Agreement.

                                      -14-
<PAGE>

     5.15.  Remedies on Default.  If any one or more of the Events of Default
            -------------------
shall occur and be continuing or shall exist, the Lender may (i) to the full
extent permitted by law, take possession and control of all or any part of the
Collateral and Proceeds thereof and the books and records pertaining thereto,
with or without judicial process, and (ii) without demand or notice (and if
notice is required by law, after ten days prior written notice), proceed to
exercise one or more of the rights and remedies accorded to a secured party by
the UCC and otherwise by law or by the terms of the Loan Agreement or this
Agreement. The Lender's rights and remedies shall include without limitation the
power to (i) sell all or any portion of the Collateral at public or private sale
at such place and time and on such terms as the Lender may see fit (subject to
the requirements of applicable law), (ii) endorse any Instrument representing
Collateral in the name of the applicable Grantor thereto, (iii) prosecute claims
and legal actions regarding Accounts, other Receivables and General Intangibles,
(iv) perform any agreement or contract which constitutes Collateral and (v)
sell, assign, license, sublicense or otherwise dispose of, all right, title and
interest in and to any General Intangibles included in the Collateral
(including, without limitation, assignments, recordings, registrations and
applications therefor in the United States Patent and Trademark Office, the
United States Copyright Office or any similar domestic or foreign office or
agency) and for the purpose of recording, registering and/or filing, or
accomplishing any other formality with respect to, the foregoing, execute and
deliver any and all agreements, documents, instruments of assignment or other
papers necessary or advisable to effect such purpose. Without precluding any
other methods of sale, the sale of Collateral shall be deemed to have been made
in a commercially reasonable manner if conducted in conformity with reasonable
commercial practices of secured lenders disposing of similar property, but in
any event, the Lender may sell the Collateral on such terms as the Lender may
choose without assuming any credit risk and without any obligation to advertise
or give notice of any kind not expressly required under this Agreement, by the
UCC or otherwise. All of the rights and remedies of the Lender under this
Agreement shall be cumulative and not exclusive of other rights and remedies
which it otherwise would have, whether under the Loan Agreement, this Agreement,
the UCC or otherwise. After the occurrence of an Event of Default, each Grantor
shall, upon the request of the Lender, promptly assemble so much of the
Collateral (including, without limitation, all books and records relating
thereto) in its possession as is capable of physical delivery and make the same
available to the Lender at such locations as may be reasonably designated by the
Lender and shall permit the Lender, or the Lender's representatives and agents,
to enter any premises where all or any part of the Collateral, or the books and
records relating thereto, or both, are located, to take possession of all or any
part of the Collateral and to remove all or any part of the Collateral. The
right of the Lender to have the Collateral assembled and made available to it is
of the essence of this Agreement, and the Lender may, at its election, enforce
such right by a bill in equity for injunctive relief for specific performance.
The Lender shall not be under any obligation to marshal any assets in favor of
any Grantor or any other Person or against or in payment of all or any of the
Secured Obligations.

     5.16.  Application of Proceeds. Any Collateral or Proceeds of the
            -----------------------
Collateral held, received or realized upon at any time by the Lender (except,
when no Default or Event of Default has occurred and continues or exists, such
moneys payable to any Grantor under insurance policies which such Grantor may
use to repair or replace Collateral pursuant to subsection 5.6.4 hereof) shall
be applied as follows:

                                      -15-
<PAGE>

            5.16.1.   first, to reimburse the Lender for all expenses and fees
incurred for which the Borrower or any other Borrower Entity is obligated to pay
the Lender under and in accordance with the Loan Agreement, the Note, this
Agreement and/or any other Loan Document (including, without limitation,
reasonable attorneys' fees and other legal expenses);

            5.16.2.   second, the satisfaction of all accrued and unpaid
interest on the Secured Obligations (including any interest which, but for the
provisions of the Bankruptcy Code, would have accrued on such amounts);

            5.16.3.   third, the satisfaction of the principal amounts of the
Secured Obligations outstanding; and

            5.16.4.   fourth, the balance, if any, to the Grantors or as
otherwise required by law.
     If the proceeds of sale, collection or other realization of or upon the
Collateral granted to the Lender by the Grantors under this Agreement are
insufficient to cover the costs and expenses of such realization and the payment
in full of the Secured Obligations, the Grantors shall remain liable, jointly
and severally, for any deficiency.  If a surplus results after lawful
application of such proceeds, the Grantors shall be entitled to a pro rata share
of any such surplus.

     5.17.  Attorney-in-Fact.  Each Grantor hereby irrevocably constitutes and
            ----------------
appoints the Lender and any officer or agent thereof, with full power of
substitution, as its true and lawful attorney-in-fact with full irrevocable
power and authority in the place and stead of such Grantor and in the name of
such Grantor or in its own name, from time to time in the Lender's discretion,
for the purpose of carrying out the terms of this Agreement, to take any and all
appropriate action and to execute and deliver any and all documents and
instruments which may be necessary or desirable to accomplish the purposes of
this Agreement and, without limiting the generality of the foregoing, hereby
gives the Lender the power and right, on behalf of such Grantor, without notice
to or assent by such Grantor, to do the following:

            5.17.1.  to do all acts and things which the Lender may deem
necessary or advisable to preserve, perfect and continue perfected the Lender's
security interest in the Collateral (including, without limitation, the signing
of financing, continuation or other similar statements and notices on behalf of
the Grantors);

            5.17.2.  to effect any insurance called for by the terms of this
Agreement and to pay all or part of the premiums therefor, and to make, settle
and adjust all claims under such Grantor's insurance policies and to endorse any
draft or check which may be payable to such Grantor in order to collect the
proceeds of such insurance or any returned or unearned premiums with respect
thereto;

            5.17.3.  to ask, demand, collect, receive and give acquittance and
receipts for any and all moneys due and to become due under any Collateral and,
in the name of such Grantor or its own name or otherwise, to take possession of
and endorse and collect any checks, drafts, notes, acceptances or other
Instruments for the payment of moneys due under any Collateral and to file any
claim or to take any other

                                      -16-
<PAGE>

action or proceeding in any court of law or equity or otherwise deemed
appropriate by the Lender for the purpose of collecting any and all such moneys
due under any Collateral whenever payable;

           5.17.4.   to pay or discharge charges or liens levied or placed on,
or threatened against, the Collateral (other than the Permitted Encumbrances);

           5.17.5.   to direct any party liable for any payment under any of the
Collateral to make payment of any and all moneys due, and to become due
thereunder, directly to the Lender or as the Lender shall direct, and to receive
payment of and receipt for any and all moneys, claims and other amounts due, and
to become due at any time, in respect of or arising out of any Collateral;

           5.17.6.   to sign and endorse any invoices, freight or express bills,
bills of lading, storage or warehouse receipts, drafts against debtors,
assignments, verifications and notices in connection with accounts and other
Documents constituting or relating to the Collateral;

           5.17.7.   to commence and prosecute any suits, actions or proceedings
at law or in equity in any court of competent jurisdiction to collect the
Collateral or any part thereof and to enforce any other right in respect of any
Collateral;

           5.17.8.   to defend any suit, action or proceeding brought against
such Grantor with respect to any Collateral;

           5.17.9.   to settle, compromise or adjust any suit, action or
proceeding described above and, in connection therewith, to give such discharges
or releases as the Lender may deem appropriate; and

           5.17.10.  to sell transfer, pledge, make any agreement with respect
to or otherwise deal with any of the Collateral as fully and completely as
though the Lender were the absolute owner thereof for all purposes, and to do,
at the Lender's option and at the expense of such Grantor, at any time, or from
time to time, all acts and things which the Lender reasonably deems necessary to
protect, preserve or realize upon the Collateral and the Lender's lien therein,
in order to effect the intent of this Agreement, and as fully and effectively as
such Grantor might do;

provided that the Lender shall be permitted to take the actions described in
- --------
subsections 5.17.3  through 5.17.10 only upon the occurrence and during the
continuation of an Event of Default. Each Grantor hereby ratifies, to the extent
permitted, all that such attorneys lawfully do or cause to be done by virtue
hereof. The power of attorney granted hereunder is a power coupled with an
interest and shall be irrevocable until the Secured Obligations are indefeasibly
paid in full and the Loan Agreement is terminated.

     5.18. Continuing Validity of Obligations.
           ----------------------------------

           5.18.1. The agreements and obligations of the Grantors hereunder
are continuing agreements and obligations and are absolute and unconditional
irrespective of (i) the genuineness, validity or enforceability of the Note or
any other instrument or instruments now or hereafter evidencing the

                                      -17-
<PAGE>

Secured Obligations or any part thereof or of the Loan Agreement, this
Agreement, the Guaranty, any other Loan Document or any other agreement or
agreements now or hereafter entered into by the Lender and the Borrower and/or
any other Borrower Entity pursuant to which the Secured Obligations or any part
thereof is issued, guaranteed or secured or (ii) any other circumstance which
might otherwise constitute a legal or equitable discharge of such agreements and
obligations other than payment in full of the Secured Obligations and the
termination of the Lender's obligation to lend to the Borrower.

            5.18.2.   Without limitation upon the foregoing, such agreements and
obligations shall continue in full force and effect as long as the Secured
Obligations or any part thereof remains outstanding and unpaid or any obligation
of the Lender to lend to the Borrower has not been terminated (whether any Loans
are outstanding) and shall remain in full force and effect without regard to and
shall not be released, discharged or in any way affected by (i) any renewal,
refinancing or refunding of the Secured Obligations in whole or in part, (ii)
any extension of the time of payment of the Note or other instrument or
instruments now or hereafter evidencing the Secured Obligations or any part
thereof, (iii) any compromise or settlement with respect to the Secured
Obligations or any part thereof, or any forbearance or indulgence extended to
the Borrower or any other Borrower Entity, (iv) any amendment to or modification
of the terms of the Note or other instrument or instruments now or hereafter
evidencing the Secured Obligations or any part thereof or of the Loan Agreement,
the Guaranty, any other Security Document or any other agreement or agreements
now or hereafter entered into by the Lender, the Borrower or any other Borrower
Entity pursuant to which the Secured Obligations or any part thereof is issued
or secured, (v) any substitution, exchange or release of, or failure to
preserve, perfect or protect, or other dealing in respect of, the Collateral or
any other property or any security for the payment of the Secured Obligations or
any part thereof, (vi) any bankruptcy, insolvency, arrangement, composition,
assignment for the benefit of creditors or similar proceeding commenced by or
against the Borrower or any other Grantor or (vii) any other matter or thing
whatsoever whereby the agreements and obligations of the Borrower under the
Note, the Loan Agreement or any other Security Document or any Grantor
hereunder, under the Guaranty, or any other Security Document would or might
otherwise be released or discharged other than payment in full of the Secured
Obligations and termination of the Lender's obligation to lend to the Borrower.
Each Grantor hereby waives notice of the acceptance of this Agreement by the
Lender.

            5.18.3.   To the extent that the Borrower, any other Borrower Entity
or any other guarantor or grantor makes a payment or payments to the Lender or
the Lender receives any payment or proceeds of the Collateral, which payment or
proceeds or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside or required to be repaid to such Person or
a trustee, receiver or any other party under any bankruptcy law, state or
federal law, common law or equitable cause of action, then, to the extent of
such payment or proceeds, the Secured Obligations or portion thereof intended to
be satisfied and this Agreement shall be revived and continue in full force and
effect, as if such payment or proceeds had not been received by the Lender.

     5.19.  Defeasance.  At such time as the Borrower may no longer borrow funds
            ----------
under the Loan Agreement and upon payment in full of the Secured Obligations and
the termination of all obligations of the Lender to lend funds to the Borrower
under the Loan Agreement, this Agreement shall terminate and be of no further
force and effect (except for the provisions of subsection 5.18.3 and Section 6.1
hereof which

                                      -18-
<PAGE>

shall survive), and in such event the Lender shall, at the expense of the
Grantors and without recourse, representation or warranty, redeliver and
reassign to each Grantor its remaining Collateral and take all action necessary
to terminate the Lender's security interest in the Collateral. This Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns.

     5.20. Limitation of Duty of the Lender.  The powers conferred on the Lender
           --------------------------------
under this Agreement are solely to protect the Lender's interest in the
Collateral and shall not impose any duty upon it to exercise any such powers.
The Lender shall be accountable only for amounts that it actually receives as a
result of the exercise of such powers and neither the Lender nor any of its
officers, directors, employees or agents shall be responsible to any Grantor for
any act or failure to act, except for willful misconduct.  Without limiting the
foregoing, the Lender shall be deemed to have exercised reasonable care in the
custody and preservation of the Collateral in its possession if such Collateral
is accorded treatment substantially equivalent to that which the Lender, in its
individual capacity, accords it own property consisting of the type of
Collateral involved; it being understood and agreed that the Lender shall not
have any responsibility for taking any necessary steps (other than steps taken
in accordance with the standard of care above) to preserve the rights against
any person with respect to the Collateral.

Section 6. Miscellaneous.
           -------------

     6.1.  Indemnification and Expenses.  The Grantors shall, jointly and
           ----------------------------
severally, indemnify and hold harmless the Lender from and against any and all
claims and losses arising out of or attributable to this Agreement and the
granting to the Lender of a security interest and lien in the Collateral
hereunder, except claims and losses arising from the Lender's breach hereof or
the Lender's gross negligence or willful misconduct.  The Grantors shall pay the
Lender on demand the amount of any out-of-pocket expenses (including, without
limitation, reasonable attorneys' fees and other legal expenses) incurred by the
Lender in connection with the enforcement of this Agreement, the Loan Agreement
and/or the Note and as otherwise provided in this Agreement, with interest
accruing thereon at the highest rate of interest accruing on the Loans under the
Loan Agreement.

     6.2.  Specific Performance.  In addition to all other rights and remedies
           --------------------
granted to the Lender in this Agreement, the Loan Agreement and the other Loan
Documents, the Lender shall be entitled to specific performance and injunctive
and other equitable relief, and each Grantor hereby waives any requirement for
the securing or posting of any bond or other security in connection with the
obtaining of any such specific performance and injunctive or other equitable
relief.

     6.3.  No Waiver.  No failure or delay on the part of the Lender in the
           ---------
exercise of any power, right or privilege hereunder shall impair such power,
right or privilege or be construed to be a waiver thereof, nor shall any single
or partial exercise of any such power, right or privilege hereunder preclude
other or further exercise thereof or the exercise of any other right, power or
privilege.  All rights and remedies existing under this Agreement are cumulative
to, and not exclusive of, any rights or remedies otherwise available.

                                      -19-

WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS.

     6.5.  Notices.  All notices, demands or other communications to be given or
           -------
delivered hereunder shall be given in accordance with the notice provision of

such cash dividends or distributions to the Lender.  The Lender shall hold any
such cash dividends and distributions as Collateral pursuant to this Agreement
or, at the Lender's election, shall apply

                                      -4-
<PAGE>

any such cash dividends or distributions to the reduction of any Secured
Obligations then outstanding, in such order as the Lender may elect.

5.   Voting and Other Rights.
     -----------------------

     5.1  Stock Register. At any time and from time to time (i) whether before
          --------------
or after the occurrence of any Event of Default, the Lender shall be entitled to
register this Agreement on the stock ledger and/or books of record of each of
the issuers of the Collateral, and each Pledgor agrees to cause this Agreement
to be so registered, and (ii) after the occurrence of any Event of Default and
the continuance thereof, the Lender shall be entitled to register any or all of
the Collateral in its name or the name of its nominee, and each Pledgor shall
execute such assignments and other documents, and take such other acts, all at
such Pledgor's expense, as the Lender may from time to time reasonably request
to accomplish the foregoing.

     5.2  Voting Rights.  Unless an Event of Default shall have occurred and be
          -------------
continuing or shall exist, each Pledgor shall be entitled to vote the Collateral
and to give consents, waivers and ratifications with respect to the Collateral;
provided that no vote shall be cast, or consent, waiver or ratification given,
- --------
or any action taken, that would impair the Collateral or be inconsistent with or
violate any provision of this Agreement or the Loan Agreement.  Upon the
occurrence and continuance or during the existence of any Event of Default, the
Lender shall have the right to vote the Collateral, in all matters, and grant
consents, waivers and ratifications with respect thereto in its absolute
discretion whether the Lender has transferred the Collateral to the registered
ownership of the Lender or the Lender's nominee.

6.   Representations and Warranties. Each Pledgor hereby represents, warrants,
     ------------------------------
covenants and agrees that:

          6.1 Such Pledgor is and shall be at all times the record and
beneficial owner of each item of its Collateral, and has and shall have at all
times good and marketable title thereto, free and clear of any and all liens,
charges, claims and encumbrances, except the security interest granted under
this Agreement, and such Pledgor shall defend such title against the claims and
demands of all Persons whomsoever. All of the Pledged Securities are duly
authorized, have been validly issued, and in the case of Pledged Securities
constituting capital stock, are fully paid and nonassessable.

          6.2 This Agreement has been duly authorized, executed and delivered by
such Pledgor and constitutes the legal, valid and binding obligation of such
Pledgor, enforceable against such Pledgor in accordance with its terms except to
the extent that the enforceability thereof may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws generally
affecting creditors' rights and by equitable principles (regardless of whether
enforcement is sought in equity or at law). This Agreement creates a valid
security interest in the Collateral and, upon delivery of the Collateral to the
Lender, shall constitute a valid first priority perfected lien on or security
interest in the Collateral.

                                      -5-
<PAGE>

     6.3  No security agreement, financing statement, equivalent security or
lien instrument, or continuation statement covering all or any part of the
Collateral is on file or of record in any public office other than those
documents reflecting liens on the Collateral in favor of the Lender.

     6.4  The certificates described on Schedule I hereto evidence all of
                                        ----------
the issued and outstanding partnership units, limited liability company
interests and shares of capital stock (as applicable) of each Pledgor (other
than the Borrower) and its Subsidiaries which are owned by each Pledgor as of
the date of execution of this Agreement, and each Pledgor has delivered to the
Lender all stock certificates or other instruments evidencing any of the Pledged
Securities, in each case duly endorsed in blank to the Lender (or with
appropriate irrevocable stock powers duly executed in blank and undated).

     6.5  Except for the Pledged Securities and the Equity Rights, such
Pledgor does not own nor does it have the right to acquire any capital stock or
securities of or other ownership interest in any Subsidiary.

     6.6  Such Pledgor's place where its records concerning the Collateral
are kept is as set forth on Schedule III hereto, and such Pledgor shall not
                            ------------
change such principal place of business or remove such records unless it has
taken such action as is necessary to cause the security interest of the Lender
in the Collateral to continue to be perfected. Such Pledgor shall not change its
principal place of business or the place where its records concerning the
Collateral are kept without giving at least thirty (30) days prior written
notice thereof to the Lender.

     6.7  No consent approval or authorization of or designation or filing
with any governmental authority on the part of such Pledgor is required in
connection with the pledge and security interest granted under this Agreement,
or the exercise of the Lender of the voting and other rights provided for in
this Agreement, except for the filing of UCC-1 financing statements.

     6.8  The execution, delivery and performance of this Agreement by such
Pledgor will not violate any provision of any applicable law or regulation or of
any order, judgment, writ, award or decree of any court, arbitrator or
governmental authority, domestic or foreign, or of the charter or by-laws of
such Pledgor or of any securities issued by such Pledgor or of any mortgage,
indenture, lease, contract, or other agreement, instrument or undertaking to
which such Pledgor is a party or which purports to be binding upon such Pledgor
or upon any of its respective assets, and will not result in the creation or
imposition of any lien, charge or encumbrance on or security interest in any of
the assets of such Pledgor except as contemplated by this Agreement.

     6.9  Such Pledgor assumes full responsibility for taking any and all
steps to preserve its and the Lender's rights with respect to the Collateral
against all prior parties. The Lender shall be deemed to have exercised
reasonable care in the preservation and custody of such of the Collateral as may
be in the Lender's possession if the Lender takes such action for that purpose
as such Pledgor shal l reasonably request in writing; provided that such
                                                      --------
requested action shall not, in the judgment of the Lender, impair the Lender's
prior security interest in such Collateral or its rights in or the value of such
Collateral; and provided further that such written request is received by the
                -------- -------
Lender in sufficient time to permit the Lender to take the

                                      -6-
<PAGE>

requested action. In the absence of such written request, the Lender shall be
deemed to have exercised reasonable care in the custody and preservation of the
Collateral in its possession if the Collateral is accorded treatment
substantially equal to that which the Lender accords its own property.

7.  Ownership Interests.  Except as set forth on Schedule IV, (i) the Pledged
    -------------------                          -----------
Securities represent 100% of the capital stock or securities or other ownership
interests of each Subsidiary of the Borrower and (ii) there are no options,
warrants, convertible securities or other rights to acquire the capital stock or
securities or other ownership interests of any Subsidiary of the Borrower.

8.  Records.   Each Pledgor shall keep accurate and complete records with
    -------
respect to each item and category of the Collateral and shall furnish copies of
such records to the Lender with reasonable promptness from time to time upon
request of the Lender.

9.  Preservation and Protection of Security Interest.  Each Pledgor shall
    ------------------------------------------------
preserve and protect the Lender's security interest in the Collateral and shall,
at its own cost and expense, cause such security interest in the Collateral to
be perfected and continue perfected so long as the Secured Obligations or any
portion thereof are outstanding and unpaid and so long as the Borrower may
borrow funds and the Lender has any obligation to advance funds to the Borrower
under the Loan Agreement (by means including, without limitation, the execution
and delivery of all instruments, documents and securities to the Lender with
endorsements and documents of transfer satisfactory to the Lender), and for such
purposes each Pledgor shall from time to time at the request of the Lender file
or record, or cause to be filed or recorded, such instruments, documents and
notices (including, without limitation, financing statements and continuation
statements) or deliver to the Lender such stock certificates or other
instruments as the Lender may deem necessary or advisable from time to time to
perfect and continue perfected such security interests.  Each Pledgor shall do
all such other acts and things and shall execute and deliver all such other
instruments and documents (including, without limitation, further security
agreements, pledges, endorsements, assignments and notices) as the Lender may
deem necessary or advisable from time to time to perfect and preserve the
priority of such security interests in the Collateral, as a perfected security
interest in the Collateral, prior to the rights of any other secured party or
lien creditor.  The Lender, and its officers, employees and authorized agents,
or any of them, are hereby irrevocably appointed the attorneys-in-fact of each
Pledgor to do, at such Pledgor's expense, all acts and things which the Lender
may deem necessary or advisable to preserve, perfect and continue perfected the
Lender's security interests in the Collateral (including, without limitation,
the signing of financing, continuation or other similar statements and notices
on behalf of each Pledgor), which appointment is irrevocable and coupled with an
interest.

10.  Covenants of the Borrower.  Each Pledgor covenants and agrees with the
     -------------------------
Lender that from and after the date of this Agreement and until the Secured
Obligations are fully satisfied and the Borrower may no longer borrow funds and
the Lender no longer has any obligation to advance funds to the Borrower under
the Loan Agreement:

      10.1 Limitation on Liens on Collateral. Such Pledgor shall not create,
           ---------------------------------
permit or suffer to exist, and shall defend the Collateral against, and take
such other action as is necessary to remove, any lien on or security interest in
the Collateral (other than liens in favor of the Lender), and shall defend the
right, title and interest of the Lender in and to any of such Pledgor's right,
title

                                      -7-
<PAGE>

and interest of the Lender in and to any of such Pledgor's right, title and
interest in and to the Collateral and to any proceeds thereof against the claims
and demands of all other Persons whomsoever.

     10.2 Limitation on Disposition. Such Pledgor shall not sell, assign,
          -------------------------
exchange or otherwise transfer, or grant any options with respect to, any of the
Collateral or any interest therein, or attempt or contract to do so (other than
the pledge and security interest granted hereunder) without the prior written
consent of the Lender.

     10.3 Notices. Such Pledgor shall advise the Lender promptly, in reasonable
          -------
detail, of (i) any lien, security interest, encumbrance or claim made or
asserted against any of the Collateral, (ii) any material change in the
composition of the Collateral (including, without limitation, information
regarding the issuance or creation of Equity Rights) and (iii) the occurrence of
any other event which might have a material adverse effect on the value of the
Collateral or on the security interests created hereunder.

     10.4 Additional Securities.  Such Pledgor shall (i) not issue any Pledged
          ---------------------
Securities, Other Securities, Equity Rights or other securities in addition to
or in substitution for the Pledged Securities, except to any Borrower Entity or
as permitted under the Loan Agreement, (ii) immediately upon its acquisition
(directly or indirectly) thereof, pledge to the Lender hereunder any and all
additional shares of stock, other securities or ownership interests issued by
its Subsidiaries and (iii) shall pledge to the Lender hereunder, immediately
upon its acquisition (directly or indirectly) hereof, any and all shares of
stock, other securities or ownership interests of any entity which, after the
date of this Agreement, becomes a direct or indirect Subsidiary of such Pledgor.

     10.5 Further Assurances. From time to time upon the request of the Lender,
          ------------------
such Pledgor shall, and shall cause its Subsidiaries to, execute and deliver
such further documents and do such further acts and things as the Lender may
reasonably request to effectuate the provisions of this Agreement (including,
without limitation, the making of any filings pursuant to the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended).

11.  The Lender's Appointment as Attorney-in-Fact.
     --------------------------------------------

     11.1 Each Pledgor hereby irrevocably constitutes and appoints the Lender
and any officer or agent thereof, with full power of substitution, as its true
and lawful attorney-in-fact with full irrevocable power and authority in the
place and stead of such Pledgor and in the name of such Pledgor or in its own
name, from time to time in the Lender's discretion, for the purpose of carrying
out the terms of this Agreement, to take any and all appropriate action and to
execute and deliver any and all documents and instruments which may be necessary
or desirable to accomplish the purposes of this Agreement. Without limiting the
generality of the foregoing and subject to each Pledgor's rights under Section 5
hereof, each Pledgor hereby gives the Lender and any officer or agent thereof,
as such attorney-in-fact, the power and right, on behalf of such Pledgor,
without notice to or assent by such Pledgor, to do the following:

          11.1.1  to defend any suit, action or proceeding brought against such
Pledgor with respect to any Collateral;

                                      -8-
<PAGE>

          11.1.2  to pay or discharge taxes, liens, security interests or other
encumbrances levied or placed on or threatened against the Collateral;

          11.1.3  to direct any party liable for any payment under any of the
Collateral to make payment of any and all moneys due and to become due
thereunder directly to the Lender or as the Lender shall direct;

          11.1.4  to receive payment of and receipt for any and all moneys,
claims and other amounts due and to become due at any time in respect of or
arising out of any Collateral;

          11.1.5  to endorse and collect any checks, drafts, notes, acceptances
or other instruments for the payment of moneys due under any Collateral;

          11.1.6  to commence and prosecute any suits, actions or proceedings at
law or in equity in any court of competent jurisdiction to collect the
Collateral or any portion thereof and to enforce any other right in respect of
the Collateral;

          11.1.7  to settle, compromise or adjust any suit, action or proceeding
described above and, in connection therewith, to give such discharges or
releases as the Lender may deem appropriate;

          11.1.8  to participate in any recapitalization, reclassification,
reorganization, consolidation, redemption, stock split, merger or liquidation of
any issuer of the Collateral and, in connection therewith, may deposit or
surrender control of the Collateral in exchange therefor and take such other
action as deemed proper by the Lender in connection therewith; and

          11.1.9  generally, to sell, transfer, pledge, vote, make any agreement
with respect to or otherwise deal with any of the Collateral as fully and
completely as though the Lender were the absolute owner thereof for all
purposes, and to do, at the Lender's option and at such Pledgor's expense, at
any time, or from time to time, all acts and things which the Lender reasonably
deems necessary to protect, preserve or realize upon the Collateral and the
Lender's security interest therein, to effect the intent of this Agreement, all
as fully and effectively as such Pledgor might do;

provided that the Lender shall be permitted to take the actions described in
- --------
subsections 11.1.3 through 11.1.9 only upon the occurrence and during the
continuation of an Event of Default.

     11.2  Any and all such amounts received by the Lender as attorney-in-fact
for each Pledgor may, in the sole discretion of the Lender, be held by the
Lender as collateral security. Each Pledgor hereby ratifies, to the extent
permitted by law, all that such attorneys shall lawfully do or cause to be done
by virtue hereof. This power of attorney is a power coupled with an interest and
shall be irrevocable until the Secured Obligations are indefeasibly paid in full
and the Loan Agreement is terminated.

                                      -9-
<PAGE>

     11.3  The powers conferred on the Lender hereunder are solely to protect
the Lender's interests in the Collateral and shall not impose any duty upon it
to exercise any such powers. The Lender shall be accountable only for amounts
that it actually receives as a result of the exercise of such powers, and
neither it nor any of its officers, directors, employees or agents shall be
responsible to any Pledgor for any act or failure to act, except for its own
gross negligence or willful misconduct.

     11.4  Each Pledgor also authorizes the Lender, at any time and from time to
time upon the occurrence and during the continuance or existence of any Event of
Default, to execute, in connection with the sale provided for in Section 12 of
this Agreement, any endorsements, assignments or other instruments of conveyance
or transfer with respect to the Collateral.

12.  Remedies on Default.
     -------------------

     12.1  If any Event of Default shall occur and be continuing or shall exist,
the Lender may take possession and control of all or any part of the Collateral
(including Proceeds thereof) and books and records pertaining thereto, with or
without judicial process, and, without demand or notice (and if notice is
required by law, after ten days prior written notice), may proceed to exercise
one or more of the rights and remedies accorded a secured party by the UCC and
otherwise by law or by the terms of the Loan Agreement or this Agreement. The
Lender's rights and remedies shall include, without limitation, the power to
sell, lease, assign, give options to purchase or otherwise dispose of and
deliver all or any portion of the Collateral at public or private sale or sales
at such place and time and on such terms as the Lender may see fit, and to
endorse in the name of the appropriate Pledgor any instrument representing
Collateral. All of the rights and remedies of the Lender under this Agreement
shall be cumulative and not exclusive of other rights and remedies which it
otherwise would have, whether under the Loan Agreement, this Agreement, the UCC,
the other Security Documents or otherwise. The Lender shall not be under any
obligation to marshal any assets in favor of any Pledgor or any other Person or
against or in payment of all or any part of the Secured Obligations.

     12.2  Each Pledgor agrees that in any sale of any of the Collateral, the
Lender is authorized to comply with any limitation or restriction in connection
with such sale which it is advised by its counsel is appropriate (i) to avoid
violation of applicable law (including, without limitation, procedures
restricting the number of prospective bidders and purchasers, requiring that
prospective bidders and purchasers have certain qualifications and restricting
prospective bidders and purchasers to persons who shall represent and agree that
they are purchasing for their own account for investment and not with a view to
the distribution or resale of any Pledged Securities, Other Securities or Equity
Rights they purchase), or (ii) to obtain any required approval of such sale or
of a purchase of such sale by any governmental regulatory authority or official.
Each Pledgor further agrees that such compliance shall not result in any such
sale being deemed not to have been made in a commercially reasonable manner, nor
shall the Lender be liable or accountable to any Pledgor for any discount
allowed by reason of the fact that any Pledged Securities, Other Securities or
Equity Rights are sold in compliance with any such limitation or restriction.
The Lender shall be under no obligation to delay the sale of any of the
Collateral for the period of time necessary to permit any Pledgor or any
Subsidiary of any Pledgor to register securities for public sale under the
Securities Act of

                                      -10-
<PAGE>

1933, as amended from time to time, or under applicable state securities laws,
even if such Person would agree to do so.

     12.3  If any Event of Default shall occur and be continuing or shall exist,
the Lender shall have the right, in addition to all other rights and remedies
available to it, without notice to the Borrower, to set-off against and to
appropriate and apply to the unpaid balance of the Note and all other Secured
Obligations, any obligations owing to the Borrower by the Lender and any funds
held in any manner for the account of the Borrower by the Lender, and the Lender
is hereby granted a security interest in and lien on all such debts for such
purpose. Such rights shall exist whether or not the Lender shall have made any
demand under the Loan Agreement or the Note and whether the Note and such other
obligations are matured or unmatured.

13.  Application of Proceeds.  Any Collateral (including Proceeds thereof) held
     -----------------------
or realized upon at any time by the Lender shall be applied as follows:

     13.1  first, to reimburse the Lender for expenses and fees incurred for
which the Borrower or any other Borrower Entity is obligated to pay the Lender
under and in accordance with the Loan Agreement, the Note, this Agreement and/or
any other Loan Document (including, without limitation, reasonable attorneys'
fees and other legal expenses);

     13.2  second, the satisfaction of all accrued and unpaid interest on the
Secured Obligations (including any interest which, but for the provisions of the
Bankruptcy Code, would have accrued on such amounts);

     13.3  third, the satisfaction of the principal amounts of the Secured
Obligations outstanding; and

     13.4  fourth, the balance, if any, to the Pledgors or as otherwise required
by law.

           If the proceeds of sale, collection or other realization of or upon
the Collateral granted to the Lender by the Pledgors under this Agreement are
insufficient to cover the costs and expenses of such realization and the payment
in full of the Secured Obligations, the Pledgors shall remain liable, jointly
and severally, for any deficiency. If a surplus results after lawful application
of such proceeds, the Pledgors shall be entitled to a pro rata share of any such
surplus.

14.  Limitation on the Lender's Duty in Respect of Collateral.  The powers
     --------------------------------------------------------
conferred on the Lender under this Agreement are solely to protect the Lender's
interest in the Collateral and shall not impose any duty upon it to exercise any
such powers.  The Lender shall be accountable only for amounts that it actually
receives as a result of the exercise of such powers and neither the Lender nor
any of its officers, directors, employees or agents shall be responsible to any
Pledgor for any act or failure to act, except for willful misconduct.  Without
limiting the foregoing, the Lender shall be deemed to have exercised reasonable
care in the custody and preservation of the Collateral in its possession if such
Collateral is accorded treatment substantially equivalent to that which the
Lender, in its individual capacity, accords it own property consisting of the
type of Collateral involved; it being understood and agreed that the Lender
shall not have

                                      -11-
<PAGE>

any responsibility for taking any necessary steps (other than steps taken in
accordance with the standard of care above) to preserve the rights against any
person with respect to the Collateral. Upon the request of any Pledgor, the
Lender shall account for any money received by it in respect of any foreclosure
on or disposition of the Collateral.

15.  Taxes and Charges.  Each Pledgor shall jointly and severally pay and
     -----------------
discharge all taxes, levies and other impositions levied on any Collateral owned
by it or in its possession (except to the extent that such taxes, levies and
other impositions shall not then be due or shall be contested in good faith by
appropriate proceedings diligently conducted; provided that such reserves and
                                              --------
other provisions as may be required by generally accepted accounting principles
have been duly made and recorded on the appropriate Pledgor's financial
records).  If any Pledgor shall fail to do so, the Lender may (but shall not be
obligated to) pay such taxes, levies or impositions for the account of such
Pledgor (without waiving or releasing any obligation or default by such Pledgor
hereunder), and the amount thereof shall be added to the Secured Obligations and
shall be payable upon demand with interest accruing thereon at the highest rate
of interest accruing on the Loans under the Loan Agreement.

16.  Continuing Validity of Obligations.
     ----------------------------------

     16.1 Continuing Validity of Obligations.
          ----------------------------------

          16.1.1  The agreements and obligations of each Pledgor hereunder are
continuing agreements and obligations and are absolute and unconditional
irrespective of (i) the genuineness, validity or enforceability of the Note or
any other instrument or instruments now or hereafter evidencing the Secured
Obligations or any part thereof or of the Loan Agreement, this Agreement, the
Guaranty, any other Loan Document or any other agreement or agreements now or
hereafter entered into by the Lender and the Borrower and/or any other Borrower
Entity pursuant to which the Secured Obligations or any part thereof is issued,
guaranteed or secured or (ii) any other circumstance which might otherwise
constitute a legal or equitable discharge of such agreements and obligations
other than payment in full of the Secured Obligations and the termination of the
Lender's obligation to lend to the Borrower.

          16.1.2  Without limitation upon the foregoing, such agreements and
obligations shall continue in full force and effect as long as the Secured
Obligations or any part thereof remains outstanding and unpaid or any obligation
of the Lender to lend to the Borrower has not been terminated (whether any Loans
are outstanding) and shall remain in full force and effect without regard to and
shall not be released, discharged or in any way affected by (i) any renewal,
refinancing or refunding of the Secured Obligations in whole or in part, (ii)
any extension of the time of payment of the Note or other instrument or
instruments now or hereafter evidencing the Secured Obligations or any part
thereof, (iii) any compromise or settlement with respect to the Secured
Obligations or any part thereof, or any forbearance or indulgence extended to
the Borrower or any other Borrower Entity, (iv) any amendment to or modification
of the terms of the Note or other instrument or instruments now or hereafter
evidencing the Secured Obligations or any part thereof or of the Loan Agreement,
the Guaranty, any other Security Document or any other agreement or agreements
now or hereafter entered into by the Lender, the Borrower or any other Borrower
Entity pursuant to which the Secured Obligations or any part thereof is issued
or secured, (v) any substitution,

                                      -12-
<PAGE>

exchange or release of, or failure to preserve, perfect or protect, or other
dealing in respect of, the Collateral or any other property or any security for
the payment of the Secured Obligations or any part thereof, (vi) any bankruptcy,
insolvency, arrangement, composition, assignment for the benefit of creditors or
similar proceeding commenced by or against the Borrower or any Pledgor or (vii)
any other matter or thing whatsoever whereby the agreements and obligations of
the Borrower under the Note, the Loan Agreement or any other Security Document
or of any Pledgor hereunder, under the Guaranty or any other Security Document
would or might otherwise be released or discharged other than payment in full of
the Secured Obligations and the termination of the Lender's obligation to lend
to the Borrower. Each Pledgor hereby waives notice of the acceptance of this
Agreement by the Lender.

          16.1.3  To the extent that the Borrower, any other Borrower Entity or
any other guarantor or pledgor makes a payment or payments to the Lender or the
Lender receives any payment or proceeds of the Collateral, which payment or
proceeds or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside or required to be repaid to such Person or
a trustee, receiver or any other party under any bankruptcy law, state or
federal law, common law or equitable cause of action, then, to the extent of
such payment or proceeds, the Secured Obligations or portion thereof intended to
be satisfied and this Agreement shall be revived and continue in full force and
effect, as if such payment or proceeds had not been received by the Lender.

17.  Defeasance.  At such time as the Borrower may no longer borrow funds under
     ----------
the Loan Agreement and upon payment in full of the Secured Obligations and the
termination of all obligations of the Lender to advance funds to the Borrower
under the Loan Agreement, this Agreement shall terminate and be of no further
force and effect (except for the provisions of Sections 16 and 18 hereof which
shall survive), and in such event Lender shall, at the expense of the Pledgors
and without recourse, representation or warranty, redeliver and reassign to each
Pledgor its remaining Collateral and take all action necessary to terminate the
Lender's security interest in the Collateral.  This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns.

18.  Miscellaneous.
     -------------

     18.1  Indemnification and Expenses. The Pledgors shall, jointly and
           ----------------------------
severally, indemnify and hold harmless the Lender from and against any and all
claims and losses arising out of or attributable to this Agreement, except
claims and losses arising from the Lender's breach hereof or the Lender's gross
negligence or willful misconduct. The Pledgors shall pay the Lender on demand
the amount of any out-of-pocket expenses (including, without limitation,
reasonable attorneys' fees and other legal expenses) incurred by the Lender in

Harris Trust and Savings Bank
111 West Monroe Street
Chicago, Illinois 60690

Gentlemen:

     ZEFER CORP., a Delaware corporation (the "Company") hereby requests that
borrowings under its $20,000,000 revolving line of credit granted by Harris
Trust and Savings Bank be made and documented upon the following terms and
conditions. You agree until further notice that upon oral advice by telephone
received by you from time to time from authorized persons listed in this letter
that we wish to borrow money, you will lend and deposit to such accounts from
time to time as specified by our written direction (the "Amount") such sums of
money as may be mutually agreed upon. We agree to confirm such borrowings in
writing by mailing on the same day a letter in the form attached hereto as
Exhibit A signed by any one of the following officers:

                                Deirdre Aubuchon
                                Sean Mullaney
                                Phillip Canfield
                                Timothy McAdam

It is understood, however, that pending receipt of such letter by you in
the ordinary course of the mails, that any sums of money borrowed by telephone
on advice of an authorized person or a person purporting to be an authorized
person in accordance with the foregoing arrangement shall immediately be
credited to the Account, and we shall be obligated to repay to you the sums so
borrowed at the time and with the interest set forth in this letter
notwithstanding that any such borrowing is not confirmed as contemplated above.

     All such borrowings shall be repaid by us upon your demand, but they may,
at our election in any instance, be repaid at any time upon telephonic advice to
you.

     All borrowings made by us under our line of credit from you shall bear
interest prior to maturity at the rate per annum which is equal to the rate per
annum which is equal at all times to the rate from time to time announced by you
as your prime commercial rate, with any change in the interest rate on such
borrowings by virtue of a change in such prime commercial rate to be and become
effective as of and on the date of this relevant change in such prime commercial
rate. Interest shall be computed on the basis of a year of 360 days and actual
days elapsed and shall be payable on the last day of each month and upon demand.

     All borrowings hereunder shall be made against and evidenced by a
promissory note of the Company payable to your order in the aggregate principal
amount of $20,000,000, such note to mature as set forth in, and to be
otherwise in the form of Exhibit B attached hereto (the "Note"). You agree that
notwithstanding the fact that the Note is in the principal amount of
$20,000,000, it shall evidence only the actual principal amount of borrowings
made by us from time to time under our line of credit from you and you agree
that if you transfer or assign the Note you will stamp thereon a statement of
the actual principal amount evidenced thereby at the time of transfer. We agree
that in any action or proceeding instituted to collect or enforce collection of
the Note, the amount shown as owing you on your records shall be prima facie
evidence of the unpaid balance of principal and interest on the Note.

                                       1

accordance with the terms of this Agreement, you shall be entitled to rely on
advice given by any person purporting to be any one of such officers and shall

of any officers and/or employees authorized to borrow funds by telephonic
advice.

office in Chicago, Illinois or unless and until the Company has received such a
notice at its address as shown on your records from you; provided that no such
termination or modification by the Company shall affect any transaction which
occurred prior to the receipt of such notice by you nor shall any such
termination or modification become effective without your written consent unless
and until all amounts which shall have been borrowed hereunder shall have been
repaid in full. This Procedures Letter and your acceptance of this Procedures
Letter as hereinafter contemplated do not constitute any commitment on your part
to make any credit available to the Company, it being understood that the making
of credit available to the Company by you from time to time shall be under and
pursuant to the revolving line of credit arrangement that this Company has with

          the lease plan (the "Lease Plan") shown on Exhibit A attached hereto
          and made a part hereof, consisting of the entire sixth (6th) floor of
          the Building agreed to contain 13,500 square feet of rentable area,
          including an allocable portion of the common areas of the Building.
          The total rentable area of the Building is agreed to be 79,654 square
          feet.

     The Premises are leased together with the right of Tenant to use for its
customers, employees and visitors, in common with others entitled thereto, such
common areas and facilities in or appurtenant to the Building as required for
access to the Premises and to lavatories, in locations as Landlord may from time
to time reasonably designate and provide.  Subject to Landlord's reasonable
security requirements, Tenant shall have access to the Premises at all times.

     2.  Use. Tenant may use the Premises only for general office purposes.
         ---
Subject to Landlord's obligations set forth in Section 10, such use and
occupation shall at all times be in compliance with the ordinances of the City
of Boston, the laws of The Commonwealth of Massachusetts and the United States
of America and any regulations under any thereof. Tenant
<PAGE>

shall not use, permit or suffer anything to be done in the Premises or anything
to be brought into or kept in the Premises, in either case, which occasions
discomfort to any other tenants or occupants of the Building, or which in
Landlord's reasonable judgment may tend to impair the reputation or appearance
of the Building or tend to interfere with the proper and economic operation of
the Building by Landlord. Tenant shall not bring or permit to be brought into or
keep in or on the Premises or elsewhere in the Building, unlawful amounts of any
inflammable, combustible or explosive fluid, material, chemical or substance, or
cause or permit any odors to emanate from or permeate the Premises.

     3. Term. Subject to the terms, covenants, agreements and conditions
        ----
contained herein, Tenant shall have and hold the Premises for a term (the
"Term") commencing on the Commencement Date and expiring at the close of the
last day of the calendar month in which the day immediately preceding the fifth
(5th) anniversary of the Commencement Date shall occur (the "Expiration Date").
For purposes hereof, (a) the "Commencement Date" shall be the 30th day following
the Delivery Date or such sooner date on which Tenant first makes use of any
portion of the Premises for the conduct of business and (b) the "Delivery Date"
shall be the date on which Landlord delivers possession of the Premises to
Tenant broom clean, free and clear of other tenants and occupants and otherwise
in a condition conforming to Landlord's obligations hereunder, any furniture or
other personal property having been removed. Tenant may terminate this lease,
without further recourse to either party, by notice given to Landlord at any
time after November 15, 1999, if the Delivery Date shall not have occurred
within fifteen (15) days following receipt of such notice. In the event this
Lease is full force and effect without default by Tenant, Tenant may extend the
Term for a period of three (3) years from the Expiration Date by given at least
nine (9) months' prior written notice thereof to Landlord. The Rent for said
extension period shall be based upon and consistent with the then fair market
rental value of the

                                      -2-
<PAGE>

Premises as the same may be mutually agreed by Landlord and Tenant and, if they
have not so agreed in writing in any case within three (3) months following the
exercise of said option, the same shall be determined by appraisers, one to be
chosen by Landlord, one to be chosen by Tenant, and a third to be selected by
the two first chosen. The unanimous written decision of the two first chosen,
without selection and participation of a third appraiser, or otherwise the
written decision of a majority of three appraisers chosen and selected as
aforesaid, shall be conclusive and binding upon Landlord and Tenant. Landlord
and Tenant shall each notify the other of its chosen appraiser within thirty
(30) days following expiration of the aforesaid three (3) month period and,
unless such two appraisers shall have reached a unanimous decision within forty-
five (45) days from said expiration, they shall within a further fifteen (15)
days elect a third appraiser and notify Landlord and Tenant thereof. Landlord
and Tenant shall each bear the expense of the appraiser chosen by it and shall
equally bear the expense of the third appraiser (if any). If, as contemplated by
this Lease, Landlord and Tenant shall not have agreed upon the Rent for said
extension period on or before the Expiration Date, then said extension period
may commence; from and after such Date until the amounts of such Rent is
determined either by agreement of the parties or by appraisal, Tenant shall make
payments of such Rent at the then current rates subject to retroactive
adjustment in conformity with and within thirty (30) days of the determination
of such Rent as hereinabove set forth.

     4. Basic Rent. (a) Tenant covenants to pay to Landlord, beginning as of the
        ----------
Commencement Date and continuing thereafter during the Term of this Lease, fixed
annual rent ("Basic Rent") at the rate of $432,000 per annum. Basic Rent shall
be payable in equal monthly installments of $36,000 each, in advance, on the
first day of every calendar month during the Term hereof, subject to proration
in the case of any partial calendar month.

                                      -3-
<PAGE>

     (b)  Except as otherwise expressly set forth herein, Tenant shall pay the
Basic Rent without set-off, deduction or demand to Landlord at its address set
forth above, or at such other place as is designated in writing from time to
time by Landlord.

     5.   Operating Cost Escalation. (a) As used in this Section, these words
          -------------------------
and terms shall have the following meanings:

          (i)  "Operating Costs" shall mean all costs incurred and expenditures
        made by Landlord for the operation and management of the Building and
        the land on which the Building is situated (hereinafter collectively
        called the "Property"). Operating Costs include, without limitation,
        costs of cleaning, security, janitorial service (including costs of
        materials and equipment); utilities and other costs related to the
        provision of heat, electricity and air conditioning (excluding heat and
        air conditioning furnished to tenants other than during normal business
        hours); maintenance and repairs to the Property (including snow removal,
        landscaping, repair of heating and air conditioning equipment, elevators
        and other non-structural Building components); payments under all
        service contracts relating to the operation and maintenance of the
        Property; reasonable management fees (not in excess of 5% of collected
        rent and other income); reasonable wages, salaries, benefits, payroll
        taxes and unemployment compensation insurance for employees of Landlord
        servicing the Property or any contractor of Landlord engaged in the
        cleaning, operation, maintenance or security of the Property; insurance
        relating to the Property; auditing expenses; payments other than Taxes
        (as hereinafter defined) to the City of Boston (including, but not
        limited to, water and sewer charges, fire service fees and other user
        fees); and supplies and all other expenses customarily incurred in
        connection with the operation of similar

                                      -4-
<PAGE>

        office buildings in the downtown Boston area. If, during the Term of
        this Lease, the Landlord shall make capital expenditures necessary or
        desirable, in the opinion of the Landlord, to meet the requirements of
        applicable laws imposed after the Delivery Date or designed to increase
        the operating efficiency of the Building or to save on labor expenses or
        to replace obsolete operating equipment, there shall be included in
        Operating Costs for the year in which the capital expenditure was made
        and in each succeeding year, an annual charge of such capital
        expenditure as determined in accordance with generally accepted
        accounting principles so long as such capital expenditure can be
        expected to achieve a reasonably-corresponding reduction of other
        Operating Costs. Operating Costs, however, shall not include (i) the
        cost of capital improvements or depreciation thereof not hereinabove
        specified (including without limitation the cost of restoration
        necessitated by fire or other casualty or by the exercise of eminent
        domain), (ii) amounts paid with respect to interest on, or amortization
        of, any mortgage, (iii) attorneys' fees incurred in connection with the
        negotiation of leases with tenants of the Building or disputes with such
        tenants unrelated to the operation or maintenance of the Property, (iv)
        any expenditures for which Landlord is reimbursed by tenants or other
        third parties (other than by tenants pursuant to expense sharing
        provisions comparable hereto), (v) rent payable under any underlying
        ground lease, (vi) the cost of renovating or otherwise improving or
        decorating, painting or redecorating space for tenants or other
        occupants of the Building, (vii) off-site overhead costs associated with
        the operation of the business entity constituting Landlord, (viii)
        salaries and benefits of executive employees above the grade of Building
        Manager, (ix) brokerage commissions, (x)

                                      -5-
<PAGE>

        advertising and other marketing costs, (xi) the cost of services or work
        provided to particular tenants of the Building which are not provided to
        Tenant or which are provided to Tenant subject to payment of an
        additional charge (currently including electricity required to provide
        heat and air conditioning to tenants during normal business hours),
        (xii) amounts paid to subsidiaries or affiliates of Landlord for
        services rendered to the Property to the extent that such amounts exceed
        the competitive costs of such services, (xiii) penalties assessed on
        account of violations by Landlord of any governmental requirement or
        (xiv) the cost of remediating any hazardous materials present on the
        Property pursuant to the provisions hereof, if necessitated by the acts
        of Landlord or its agents, employees or contractors. In addition, any
        costs relating to the Property in conjunction with other properties
        under common ownership or management shall be equitably apportioned. If
        the Building is less than fully occupied during a particular calendar
        year or if all Building tenants are not receiving the same services to
        be provided to Tenant hereunder, then Operating Costs for such year
        shall be extrapolated to an amount which reasonably approximates the
        amount which would have been incurred if the Building were fully
        occupied and such services were being provided to all Building tenants.

               (ii) "Operating Escalation Statement" shall mean a statement in
        writing signed by Landlord, setting forth the amounts payable by Tenant
        for a specified computation year pursuant to this Section and providing
        reasonable written back-up for the calculation of such amount, including
        copies of any significant invoices received by Landlord.

                                      -6-
<PAGE>

     (b)  If in any calendar year occurring during the term of this Lease, the
Operating Costs for such year exceed the Operating Costs for the Operating Cost
Base Year (as defined below), Tenant shall pay to Landlord an amount equal to
16.95% of such excess (the "Operating Cost Excess"). Such amount shall be due
and payable within thirty (30) days following receipt by Tenant of the Operating
Escalation Statement for such year. If this Lease shall commence or terminate in
the middle of a calendar year, Tenant shall be liable for only that portion of
the Operating Cost Excess in respect of such calendar year represented by a
fraction the numerator of which is the number of days of the Term which falls
within the calendar year and the denominator of which is three hundred sixty-
five (365). The Operating Cost Base Year shall mean the calendar year ending on
December 31, 1999.

     6.   Tax Escalation. (a) As used in this Section, these words and terms
          --------------
shall have the following meanings:

          (i) "Taxes" shall mean all payments, all taxes, assessments and
betterments levied, assessed or imposed by any governmental authority upon or
against the Property or Building or payments in lieu thereof, but excluding
water and sewer charges. Any such assessment or betterment shall be amortized
over the longest period permitted by applicable law such that only those
installments payable on account thereof during the Term of this Lease, together
with any interest charged to Landlord, shall be deemed included as part of Taxes
hereunder. If, at any time during the Term of this Lease, any tax or excise on
rents or other taxes, however described, are levied or assessed against Landlord
with respect to the rent reserved hereunder, either wholly or partially in
substitution for, or in addition to, real estate taxes assessed or levied on the
Property or Building, or payments in lieu thereof, such tax or excise on rents
shall be included in Taxes. Notwithstanding the foregoing, Taxes shall not
include franchise, estate, inheritance, succession, capital, levy, transfer,
income or excess profits

                                      -7-
<PAGE>

taxes assessed on Landlord nor penalties or interest on payments not made by
Landlord in a timely manner.

          (ii)   "Tax Escalation Statement" shall mean a statement in writing
signed by Landlord, setting forth the amounts payable by Tenant for a specified
computation period pursuant to this Section with a copy of Landlord's tax bill
attached thereto.

          (iii)  "Fiscal Year" shall mean the fiscal year of the City of Boston.

     (b)  If in any Fiscal Year occurring during the Term of this Lease, the
Taxes for such year exceed the Taxes for the Tax Base Year (as defined below),
Tenant shall pay to Landlord an amount equal to 16.95% of such excess (the "Tax
Excess"). Such amount shall be due and payable thirty (30) days following
receipt by the Tenant of the Tax Escalation Statement. If this Lease shall
commence or terminate in the middle of a Fiscal Year, Tenant shall be liable for
only that portion of the Tax Excess in respect of such year represented by a
fraction the numerator of which is the number of days of the Term which falls
within the Fiscal Year and the denominator of which is three hundred sixty-five
(365). The Tax Base Year shall mean the Fiscal Year ending June 30, 2000.

     (c)  If, after Tenant shall have made any payment of Tax Excess, Landlord
receives a refund of any portion of Taxes paid by Landlord, Tenant's pro rata
share of such refund, less the reasonable cost of securing the same, shall be
credited by Landlord against outstanding Rent (as defined below) or other
charges due from Tenant, if any, and any balance shall be refunded to Tenant
within thirty (30) days of receipt of same by Landlord.

     (d)  Tenant shall, if, as and when required by Landlord, with each monthly
payment of Basic Rent, make such estimated payments of Operating Cost Excess and
Tax Excess in advance as Landlord shall reasonably determine to be sufficient to
provide in the aggregate a fund adequate to pay, when due, all additional rent
required pursuant to Sections 5(b) and 6(b). Any

                                      -8-
<PAGE>

deficiency shall be payable within the time set forth in said Sections, and any
surplus shall be credited against outstanding Rent or other charges due from
Tenant, if any, and any balance shall be refunded to Tenant.

     (e)  The payments required to be made by Tenant pursuant to this Section
and Section 5, together with the Basic Rent, are hereinafter collectively called
the "Rent."

     (f)  Landlord shall retain its books and records relating to the
calculation of any "Operating Escalation Statement" or a "Tax Escalation
Statement" for at least three (3) years following the rendition thereof, and
Tenant may review said books and records within one (1) year following receipt
of the applicable Statement from Landlord.

     7.   Condition of the Premises. Landlord shall, prior to the Delivery Date,
          -------------------------
(a) render operational the freight elevator in the Building, (b) install a
locking device to restrict access to the Premises from the interior Building
stairway and (c) balance the heating, ventilating and air conditioning equipment
servicing the Premises by adjusting the output of the diffusers to accommodate
the way in which space is currently configured. In all other respects, subject
to Landlord's repair obligations hereunder, Tenant shall accept the Premises
(including existing Building window blinds, which shall be retained for Tenant's
use) "as is" on the Delivery Date, and all work necessary to prepare the
Premises for occupancy by Tenant shall be performed by Tenant in accordance with
Section 8 and the other applicable provisions of this Lease. Tenant may, at its
own risk (except with respect to the negligence or willful misconduct of
Landlord or its agents, employees or contractors), enter the Premises after the
Delivery Date in order to undertake such work.

     8.   Improvements and Alterations. (a) Tenant, at its own expense, may make
          ----------------------------
alterations, additions and improvements with Landlord's prior written consent
to the interior of the Premises which are necessary or appropriate for the
conduct of Tenant's business in

                                      -9-
<PAGE>

accordance with detailed working drawings and specifications describing such
work which have been submitted in advance to and approved in writing by Landlord
along with the identity of the contractor. Such consent or approval shall not be
unreasonably withheld or delayed in the case of any proposed work of a non-
structural nature which does not affect the common areas or facilities of the
Property and is not visible from the exterior of the Premises. In addition,
Tenant shall not be required to obtain Landlord's consent to interior painting
and similar work of a purely decorative nature so long as the quality thereof
conforms to any standard Building criteria established by Landlord. Tenant shall
pay all costs of preparing plans, drawings and specifications. Such alterations,
additions and improvements (specifically excluding movable personal property
installed by Tenant) made after the date hereof are hereinafter collectively
called the "Improvements." All the Improvements, whether placed in or attached
or made to or a part of the Premises prior to or during the Term of this Lease,
shall, unless Landlord otherwise elects and except in the case of customary
trade fixtures, become and be Landlord's property and shall be and remain part
of the Premises as of the termination of the Term. Landlord shall notify Tenant
in writing at the time Landlord approves Tenant's plans for Improvements of its
election to require Tenant to remove any or all of its Improvements upon the
expiration or earlier termination of the Term. Construction of the Improvements
shall be performed diligently and in a good and workmanlike manner and shall be
expeditiously completed in compliance with all laws, ordinances, orders, rules,
regulations and requirements. All work done in connection with the Improvements
shall comply with all requirements of insurance policies maintained by Landlord
and Tenant. Tenant, at its own expense, shall procure all permits and licenses
for the Improvements required by any governing authority having jurisdiction
over the Premises and the business to be conducted in the Premises. Tenant shall
promptly pay all costs and expenses of the Improvements, and Tenant shall
indemnify the Landlord against performance liens, costs,

                                     -10-
<PAGE>

damages and expenses in connection with all Improvements. In case of damage or
destruction of any Improvements which Landlord elected not to be a portion of
the Premises during the Term of this Lease, Tenant shall have the right to
recover its loss from any insurance company with which it has insured the same.
At the end of the Term of this Lease, if not then in default hereunder, Tenant
shall remove all of its personal property other than the Improvements (except
those Improvements which Landlord elected to require Tenant to remove). If
Landlord elects to have Tenant remove the Improvements, Landlord shall not
require removal of pipes, wires and the like from walls, ceilings or floors,
provided that Tenant properly cuts, caps and disconnects such pipes and wires
and seals them off in a safe and lawful manner flush with the applicable wall,
floor and ceiling and redecorates the area in a manner substantially consistent
with the remainder of the Premises. Tenant shall maintain the Improvements in
accordance with Section 10 during the Term of the Lease and shall be responsible
for any and all damage to the Premises, the fixtures, appurtenances and
equipment of Landlord or the Building caused by the installation, malfunction or
removal of the Improvements or Tenant's Property, as defined in Section 9.

     (b)  To protect the historical and architectural integrity and appearance
of the Building, Tenant shall not install any signs on the exterior of the
Building or Premises or in the interior of the Premises if visible from the
exterior of the Premises except as permitted by this paragraph. All signs or
lettering, if any, visible from the exterior of the Building or from the lobby,
public corridors or in any other common area or public place must be submitted
to Landlord for written approval of the size, color, design and location of such
signs or lettering before installation, which approval shall not be unreasonably
withheld or delayed. Tenant may hang its own window blinds or curtains in the
Premises, subject to Landlord's prior written approval, which approval shall not
be unreasonably withheld or delayed. Landlord shall include

                                     -11-
<PAGE>

Tenant's name and the floor location of the Premises in any directory maintained
by Landlord in the lobby of the Building.

     (c)  Subject to the provisions hereof otherwise applicable to the making of
alterations, additions and improvements in the Premises together with such
additional requirements as Landlord may reasonably prescribe, Tenant may install
cabling and wiring through vertical shafts of the Building in order to service
equipment located in the Premises. Notwithstanding the foregoing, Landlord shall
neither unreasonably withhold or delay any consent required in the case of, nor
obligate Tenant to furnish detailed working drawings and specifications
describing, such installations.

     9. Property of Tenant.  Subject to the provisions of this Section 9,
        ------------------
Tenant may place office fixtures, office equipment and the like ("Tenant's
Property") in the Premises. Tenant shall not place a load upon any floor of the
Premises exceeding the floor load per square foot area which such floor was
designed to carry and which is allowed by law. Business machines and mechanical
equipment and Tenant's other personal property shall be placed and maintained by
Tenant at its expense in settings sufficient to absorb and prevent vibration,
noise and annoyance. Except in case of the negligence or willful misconduct of
Landlord or its agents, employees or contractors, Tenant covenants and agrees
that all Tenant's Property of every kind, nature and description which may be in
or upon the Premises or Building, in the public corridors, or on the sidewalks,
area ways and approaches adjacent thereto, during the Term hereof, and any
movement of Tenant's Property, shall be at the sole risk and hazard of Tenant,
and Tenant hereby indemnifies and agrees to save Landlord harmless from and
against any liability, loss, injury, claim or suit resulting directly or
indirectly therefrom except to the extent caused by the negligence or willful
misconduct of Landlord or its agents, employees or contractors as aforesaid.

                                     -12-
<PAGE>

     10.  Maintenance and Repair. (a) Subject to Landlord's repair obligations
          ----------------------
hereunder, Tenant shall, at its sole cost and expense, maintain the Premises in
as good order, condition and repair as the same were in on the Delivery Date or
may have been put in thereafter, reasonable wear and tear and damage by fire and
other casualty excepted.  Tenant, at its own expense, shall supply all light
bulbs, tubes or similar devices for lighting the Premises.  Landlord agrees to
change all such bulbs, tubes or similar devices.

     (b) Landlord shall: (i) keep the Building structure (including without
limitation the roof) and the plumbing, electrical, heating, ventilating and air
conditioning systems and utility service lines of the Building servicing the
Premises in good and operating condition and repair (except that Tenant shall be
responsible for the cost of any repair or replacement occasioned by any act or
neglect of Tenant, its servants, agents, customers, contractors, employees or
licensees); (ii) keep the sidewalks, common corridors, stairways, elevators and
all other public portions of the Building in good and operating condition and
repair and in a reasonably clean and safe condition; and (iii) comply with
applicable governmental rules, regulations, laws and ordinances affecting the
Building or Tenant's ability to use the Premises for general office purposes,
unless a violation is caused by Tenant or any party claiming by through or under
Tenant.  Landlord reserves the right to interrupt, curtail, stop or suspend the
furnishing of any services and the operation of the plumbing, electrical,
heating, ventilating and air conditioning systems when necessary by reason of
accident or emergency or for repairs, alterations, replacements or improvements
which may become necessary or when it cannot secure supplies or labor, or by
reason of any other cause beyond its reasonable control, without liability or
any abatement of Rent being due thereby.  In exercising its rights set forth in
the preceding sentence, Landlord hereby agrees to use reasonable efforts to not
materially interfere with Tenant's use of the Premises.  Notwithstanding the
foregoing, if, as a result of any such interruption, curtailment,

                                     -13-
<PAGE>

stoppage or suspension, the Premises are substantially untenantable for thirty
(30) consecutive days, Tenant may, by notice to Landlord at any time thereafter
(unless, within five (5) days following receipt of such notice, the Premises are
no longer substantially untenantable as aforesaid), elect to terminate this
Lease with the same force and effect as if the Term had expired.

     11.  Services. (a) Landlord shall provide:
          --------

          (i)   Access to the Premises from the Building lobby during regular
Building hours (7:00 a.m. to 6:00 p.m.) on business days (Saturdays, Sundays and
legal Massachusetts holidays excepted) and, at all other times, controlled
access under conditions which will insure the security of the Building.

          (ii)  Necessary elevator facilities.

          (iii) Heat and air conditioning to the common areas of the Building
and heat and air conditioning reasonably required for the comfortable occupancy
of the Premises during normal seasonal heating periods on business days from

legal Massachusetts holidays). The Landlord shall furnish heat and air
conditioning beyond the above stated hours, provided that notice requesting such
service is delivered to Landlord before noon on the business day when such
service is required for that evening, and by noon of the preceding business day
when such service is required on a Saturday, Sunday or holiday. Landlord's
reasonable charge for supplying such additional service (currently $35.00 per
hour) shall be paid by Tenant or, alternatively, shall be shared proportionately
between Tenant and other tenants, if any, located in the relevant zone who have
requested and are receiving the benefit of such service at the same time as
Tenant (it being understood and agreed, however, that the air conditioning
equipment currently servicing the Premises does not also service any other
rentable area in the Building). Air conditioning and

                                     -14-

sole cost and expense, and Tenant shall be responsible for paying all
electricity required to provide such air conditioning and heating.

          (iv)  Cleaning and janitor service in scope, quality and frequency is
described in Exhibit C attached hereto and made a part hereof (the "Cleaning
Specifications"), provided the Premises are kept in good condition by Tenant.

Building.

     (b)  Tenant shall purchase the electrical energy required by Tenant for
operation of the lighting fixtures, equipment, appliances and heating and air
conditioning systems servicing the Premises directly from the public utility
company servicing the Building as determined by separate meters.  Landlord shall
not be liable in any way to Tenant for any failure or defect in the supply or
character of electrical energy furnished to the Premises by reason of any
requirement, act or omission of said public utility company.  Tenant's use of
electrical energy in the Premises shall not at any time exceed the capacity of
any of the electrical conductors and equipment in or otherwise serving the
Premises.

     (c)  In the event Tenant wishes to provide outside services for the
Premises over and above those services to be provided by Landlord as set forth
herein ("Outside Services"), Tenant shall first obtain the prior written
approval of Landlord, which approval shall not be unreasonably withheld or
delayed, for the installation and/or utilization of such services. Outside
Services shall include, but not be limited to, cleaning services, television,
so-called "canned

                                     -15-

music" services, security services and the like, excluding the use of caterers,
couriers and other vendors whose services are routinely engaged in connection
with specified functions or transactions.  If Landlord approves the installation
and/or utilization of Outside Services, such installation and utilization shall
be at Tenant's sole cost, risk and expense except in the case of the negligence
or willful misconduct of Landlord or its agents, employees or contractors.

     12.  Inspection. Landlord and its authorized representatives shall have the
          ----------
right at all reasonable times and with prior notice to Tenant (except in case of
emergency) to enter the Premises to inspect the same, to make repairs or
replacements therein as required by this Lease or requested by Tenant, to
exhibit the Premises to prospective tenants (but only during the final twelve
(12) months of the Term) or others, and to introduce conduits and pipes or ducts
as may be necessary with all repair and clean up to be performed by Landlord
immediately upon completion of work; provided, however, that Landlord shall use
all reasonable effort to not unreasonably disturb Tenant's use and occupancy and
to afford an opportunity for an employee of Tenant to be present while Landlord
or its authorized representatives remain in the Premises.  The exercise of any
such right shall not be deemed an eviction or disturbance of Tenant's use or
possession unless such disruptions are actually continuous and actually cause
Tenant's business to cease operations.

     13.  Casualty and Taking. (a) If the Premises or any part thereof shall be
          -------------------
damaged by fire or other casualty, Landlord shall proceed with reasonable
diligence, and at the expense of Landlord, to repair or cause such damage to be
repaired, provided however that Landlord shall in no event be responsible for
any repairs or replacements of (i) the Improvements which Landlord elected not
to be a portion of the Premises or of (ii) Tenant's Property.  If the Premises
or any part thereof shall have been rendered unfit for use and occupation
hereunder by reason of such damage, the Basic Rent or a just and proportionate
part thereof, according to the nature and

                                     -16-
<PAGE>

extent to which the Premises shall have been so rendered unfit, shall be
suspended or abated from the time of such damage until the Premises (except as
to the property which is to be repaired by or at the expense of Tenant) shall
have been restored as nearly as practicably may be to the condition in which
they were immediately prior to such fire or other casualty and a certificate of
occupancy issued permitting Tenant's use of the Premises. Landlord shall not be
liable for delays in the making of any such repairs which are due to
governmental regulations, casualties and strikes, and other causes beyond the
control of Landlord, nor shall Landlord be liable for any inconvenience or
annoyance to Tenant or injury to the business of Tenant resulting from
reasonable delays in repairing such damage. In case the Building or at least 25%
thereof is so damaged by such fire or other casualty that substantial alteration
or reconstruction (which may reasonably be expected to take nine months or
longer of actual construction time to complete) of the Building shall be
required, then, whether or not the Premises shall have been damaged by such fire
or other casualty, this Lease and the Term hereof may be terminated at the
election of Landlord or Tenant by a notice in writing of its election so to
terminate, which termination shall be effective not less than thirty (30) days
after the day on which such termination notice is received. In the event of any
such termination, this Lease and the Term hereof shall expire as of such
effective termination date and the Rent shall be apportioned as of such date;
and if the Premises or any part thereof shall have been rendered unfit for use
and occupation by reason of such damage, the Basic Rent for the period from the
date of the fire or other casualty to the effective termination date, or a just
and proportionate part thereof, according to the nature and extent to which the
Premises shall have been so rendered unfit, shall be abated and any security
deposits and other expense deposits shall be returned to the extent that such
deposits represent a period after the expiration of the Term.

                                     -17-
<PAGE>

     (b)  In the event that the Premises or any part thereof, or the whole or
any substantial part of the Building, or the access thereto, shall be taken or
appropriated by eminent domain or shall be condemned for any public or quasi-
public use, or (by virtue of any such taking, appropriation or condemnation)
shall suffer any damage (direct, indirect or consequential) for which Landlord
or Tenant shall be entitled to compensation, then (and in any such event) this
Lease and the Term hereafter may be terminated at the election of Landlord by a
notice in writing of its election so to terminate which shall be given by
Landlord to Tenant within sixty (60) days following the date on which Landlord
shall have received notice of such taking, appropriation or condemnation. In
that event, the termination date is to be sixty (60) days from Tenant's receipt
of notice from Landlord. If the entire Premises or such portion thereof or the
access thereto shall be so taken, appropriated or condemned, such that Tenant
shall be precluded from effectively utilizing the Premises, then (and in any
such event) this Lease and the Term hereof may be terminated at the election of
Tenant by a notice in writing of its election so to terminate which shall be
given by Tenant to Landlord within sixty (60) days following the date on which
Tenant shall have received notice of such taking, appropriation or condemnation.
Upon the giving of any such notice of termination (either by Landlord or Tenant)
this Lease and the Term hereof shall terminate on or retroactively as of the
date on which Landlord or Tenant, as the case may be, shall be required to
vacate any portion of the area so taken, appropriated or condemned or shall be
deprived of the means of access thereto; provided, however, that Landlord may in
Landlord's notice of termination elect to terminate this Lease and the Term
hereof retroactively as of the date on which such taking, appropriation or
condemnation became legally effective.  In the event of such termination, this
Lease and the Term hereof shall expire as of such effective termination date and
the Basic Rent shall be apportioned as of such date and any

                                     -18-
<PAGE>

security deposits and other expense deposits shall be returned to the extent
that such deposits represent a period after the expiration of the Term.

     (c) If neither party (having the right so to do) elects to terminate this
Lease and the Term hereof as provided in paragraph (b) above, Landlord shall,
with reasonable diligence and at Landlord's expense, restore the remainder of
the Premises (but not the Improvements which Landlord elected not to be a
portion of the Premises or any of Tenant's Property), or the remainder of the
means of access, as nearly as practicably to the condition as obtained prior to
such taking, appropriation or condemnation, in which event the Rent shall be
adjusted in a manner such that (i) a just proportion of the Basic Rent,
according to the nature and extent of the taking, appropriation or condemnation
and the resulting permanent injury to the Premises and the means of access
thereto, shall be permanently abated, and (ii) a just proportion of the
remainder of the Basic Rent, according to the nature and extent of the taking,
appropriation or condemnation and the resultant injury sustained by the Premises
and the means of access thereto, shall be abated until what remains of the
Premises (other than said Improvements or Tenant Property) and the means of
access thereto shall have been restored as fully as may be for permanent use and
occupation by Tenant hereunder.  Landlord shall not be liable for any delays in
such restoration which are due to governmental regulations, casualties, strikes,
unavailability of labor or materials, or other causes beyond Landlord's control,
nor shall Landlord be liable for any inconvenience or annoyance to Tenant or
injury to the business of Tenant resulting from reasonable delays in such
restoration.  Landlord expressly reserves and Tenant hereby assigns to Landlord
all rights to compensation and damages created, accrued or accruing by reason of
any such taking, appropriation or condemnation, but not including relocation
assistance payments by a governmental agency or entity nor any compensation for
damages to Tenant's property.

                                     -19-
<PAGE>

     (d) If the Premises or any part thereof or the access thereto shall be
taken, appropriated or condemned for any temporary use (i) this Lease shall be
and remain unaffected thereby and Tenant shall continue to pay the full amount
of the Rent hereunder, (ii) Tenant shall be entitled to receive for itself any
award made for such use allocable to the Term of this Lease, and (iii) Tenant,
to the extent of any award made under (ii) above, shall be responsible for any
repairs necessary to restore the Premises to their condition prior to such
taking, appropriation or condemnation, provided that if any such taking,
appropriation or condemnation extends beyond the Term of this Lease, the costs
of such repairs shall be allocated between Landlord and Tenant in proportion to
the amount of any award each receives.  Any taking, appropriation or
condemnation continuing in excess of one year shall be deemed to be a permanent
taking, appropriation or condemnation and shall be governed by paragraphs (b)
and (c) of this Section 13.

     14.  Injury and Damage.  Landlord shall not be liable for any injury or
          -----------------
damage to persons or property resulting from fire, explosion, falling plaster,
steam, gas, electricity, electrical disturbance, water, rain or snow or leaks
from any part of the Building or from the pipes, appliances or plumbing works or
from the roof, street or subsurface or from any other place or by dampness or by
any other cause of whatever nature, unless caused by or due to the act,
omission, fault, negligence or misconduct of Landlord, or its agents, employees
or contractors; nor shall Landlord or its agents be liable for any such damage
caused by other tenants or persons in the Building or caused by construction
operations of any private, public or quasi-public person.

     15.  Indemnification. (a) Tenant hereby indemnifies and covenants to save
          ---------------
Landlord harmless from and against any and all claims, liabilities or penalties
asserted by or on behalf of any person, firm, corporation or public authority:
(i) on account of or based upon any injury to

                                     -20-
<PAGE>

person, or loss of or damage to property, sustained or occurring on the Premises
on account of or based upon the act, omission, fault, negligence or misconduct
of Tenant or its agents, employees and invitees; (ii) on account of or based
upon any injury to person, or loss of or damage to property, sustained or
occurring in or about the Property and other than on the Premises (and, in
particular, without limiting the generality of the foregoing, on or about the
elevators, stairways, public corridors, sidewalks, concourses, arcades,
approaches, area ways, roof or other appurtenances and facilities used in
connection with the Building or the Premises) arising out of the use or
occupancy of the Building or the Premises by Tenant or by any person claiming
by, through or under Tenant, and caused by the act, omission, fault, negligence
or misconduct of Tenant or its agents, employees and invitees, and in addition
to and not in limitation of the foregoing subdivision (i); and (iii) on account
of or based upon (including monies due on account of) any work or thing
whatsoever done by or on behalf of Tenant or any party claiming by, through or
under Tenant on the Premises; and, in respect of any of the foregoing, from and
against all costs, expenses (including, without limitation, reasonable
attorneys' fees) and liabilities incurred in or in connection with any such
claim, or any action or proceeding brought thereon. If any action or proceeding
be brought against Landlord by reason of any such claim, Tenant, upon notice
from Landlord, shall, at Tenant's expense, resist or defend such action or
proceeding and employ counsel therefor reasonably satisfactory to Landlord, it
being agreed that such counsel as may act for insurance underwriters of Tenant
engaged in such defense shall be deemed satisfactory.

     (b) Landlord hereby indemnifies and covenants to save Tenant harmless from
and against any and all claims, liabilities, penalties, damages, losses, costs
and expenses (including reasonable attorneys' fees) asserted against or incurred
by Tenant on account of or based upon the act, omission, fault, negligence or
misconduct of Landlord or its agents, contractors or

                                     -21-
<PAGE>

employees; and, in case any action or proceeding be brought against Tenant by
reason of any of the foregoing, Landlord upon notice from Tenant shall at
Landlord's expense resist or defend such action or proceeding and employ counsel
therefor reasonably satisfactory to Tenant, it being agreed that such counsel as
may act for insurance underwriters of Landlord engaged in such defense shall be
deemed satisfactory.

     (c)  Each party, upon receiving notice of any claim against which the other
party has agreed to provide indemnification pursuant to this Section or
elsewhere in this Lease, shall promptly so notify the other party.

     16.  Insurance. (a) Tenant agrees to maintain public liability insurance in
          ---------
an amount not less than $2,000,000.00 per occurrence for personal injuries or
deaths occurring in or about the Premises and the Building and property damage
liability insurance in an amount not less than $2,000,000.00 and to submit and
maintain copies of such policies with Landlord. The insurers under such policies
and the coverage afforded thereunder shall be reasonably satisfactory to
Landlord and such policies shall name as insured parties Landlord and Tenant and
any party holding an interest to which this Lease may be subordinated pursuant
to Section 21, as their interests may appear, and shall provide twenty (20)
days' prior written notice to Landlord of lapse or cancellation.

     (b)  Tenant shall not do or omit to do or keep anything in, upon or about
the Premises, the Building or any adjacent areas which may prevent the obtaining
of any fire, liability or other insurance upon or written in connection with the
Premises or the Building or which may make any such insurance void or voidable
or otherwise invalidate the obligations of the insurer contained therein, or
which may increase the rate of any such insurance over that normally applicable
to office buildings.  Tenant agrees to pay to Landlord, upon demand and
provision by Landlord of reasonable written documentation thereof, the amount of
any extra premiums which

                                     -22-
<PAGE>

results from Tenant's failure to comply with the foregoing provisions or from
the business carried on in the Premises by Tenant, whether or not Landlord has
consented to such business.

     17.  Waiver of Subrogation. Landlord and Tenant shall each use its best
          ---------------------
efforts to cause all policies of fire, extended coverage, and other physical
damage insurance covering the Premises, the Building, and any property therein
to contain the insurer's waiver of subrogation and consent to preloss waiver of
rights over the insured. Effective only when permitted by the policy or when
such a clause is commercially available at no additional cost or premium (unless
the other party agrees to pay the same), Landlord and Tenant respectively waive
all claims and rights to recover against the other in event of loss or damage
caused by a peril (including without limitation vandalism or malicious mischief)
coverage against which is afforded by a so-called "All Risk" policy, whether or
not actually procured and without regard to any deductible.

     18.  Assignment, Mortgaging, Subletting. (a) Tenant covenants and agrees
          ----------------------------------
that neither this Lease nor the Term hereof, nor the estate hereby granted, nor
any interest herein or therein, will be assigned, mortgaged, pledged, encumbered
or otherwise transferred, and that neither the Premises, nor any part thereof,
will be encumbered in any manner by reason of any act or omission of Tenant, or
used or occupied, or permitted to be used or occupied, by anyone other than
Tenant and its employees, or for any use or purpose other than as above stated,
or be sublet, or offered or advertised for subletting, without in each case,
obtaining Landlord's prior written consent. Notwithstanding the foregoing,
Tenant shall have the privilege of assigning this Lease to, or making a sublease
or other occupancy arrangement with, any entity which is a corporate parent,
subsidiary, affiliate or successor of Tenant by way of merger or consolidation
or the acquisition of all or substantially all of Tenant's assets as a going
concern, subject, however, in all respects to all the covenants, agreements,
terms, provisions and conditions contained in this Lease; no such assignment
shall be valid unless, simultaneously therewith, Tenant shall deliver

                                     -23-
<PAGE>

to Landlord an executed counterpart of said assignment and the assignee shall
deliver to Landlord an agreement in form and substance reasonably satisfactory
to Landlord which contains an appropriate covenant of assumption by such
assignee, and no such assignment to a successor shall be valid unless prior to
said assignment Tenant shall have submitted to Landlord financial statements or
other material satisfactory to Landlord indicating that such assignee has
financial resources and a general business reputation comparable to those of
Tenant immediately prior to such assumption.

     (b)  If this Lease is assigned, or if the Premises or any part thereof be
sublet or occupied by anybody other than Tenant and its employees, Landlord may
collect the rents from such assignee or, if Tenant is in default hereunder
beyond the applicable grace period, from such subtenant or occupant, as the case
may be, and apply the net amount collected to the Rent herein reserved, but no
such assignment, subletting, occupancy or collection shall be deemed a waiver of
the requirements set forth in subparagraph (a) of this Section, the acceptance
by Landlord of such assignee, subtenant or occupant, as the case may be, as a
tenant, or a release of Tenant from the future performance by Tenant of its
covenants, agreements and obligations contained in this Lease.  The consent by
Landlord to an assignment or subletting shall not in any way be construed to
relieve Tenant from primary liability under this Lease or from obtaining the
express consent in writing of Landlord to any further assignment or subletting.
No assignment, subletting or use of the Premises shall affect the purpose for
which the Premises may be used as stated in Section 2.

     (c)  Tenant further covenants and agrees that it will not sublease space
from or take an assignment of a lease covering space in the Building from any
other Building tenant or sublease to or assign this Lease to any other Building
tenant without prior written consent from Landlord, which consent shall not be
unreasonably withheld or delayed (unless Landlord is able to make

                                     -24-
<PAGE>

available when needed and for at least the same duration space of comparable
size elsewhere in the Building).

     (d)  Except as otherwise hereinabove set forth, Landlord shall not
unreasonably withhold or delay its consent to a proposed subletting of the
Premises, provided however that Landlord may, in lieu of such consent, elect to
terminate this Lease immediately prior to the effective date of any proposed
subletting with the same force and effect as if the term hereof had expired, and
provided further that, if Landlord consents to the subletting of the Premises in
whole or in part, Tenant shall pay to Landlord 50% of any rent or other
consideration received from the subtenant in excess of the rent and other
charges payable hereunder (allocated to the sublet area on a prorata basis), net
of any brokerage commissions and other expenses reasonably incurred by Tenant
with respect to the subject transaction.

     (e)  Any consent required from Landlord pursuant to this Section shall be
deemed to have been granted unless Landlord informs Tenant to the contrary
within fifteen (15) days following Landlord's receipt of Tenant's written
request therefor, so long as such request expressly and conspicuously recites
the effect of Landlord's failure to respond thereto as aforesaid.

     19.  Default. (a) If (i) Tenant shall default in the payment of the Basic
          -------
Rent or any other charges or sums due hereunder and such default shall continue
for ten (10) days after written notice thereof by Landlord to Tenant, or (ii)
Tenant shall default in the performance of any other of its obligations and such
default shall continue for thirty (30) days after written notice thereof by
Landlord to Tenant (except that if Tenant cannot reasonably cure any such
default within said thirty (30) day period, this period may be extended for a
reasonable time, provided that Tenant commences to cure such default within the
thirty (30) day period and proceeds diligently thereafter to effect such cure),
or (iii) Tenant shall abandon the Premises (as

                                     -25-
<PAGE>

distinguished from ceasing operations therein while seeking an acceptable
assignee or subtenant), or (iv) Tenant shall file a petition under any
bankruptcy, insolvency law or code, or (v) such a petition filed against Tenant
is not dismissed within sixty (60) days, or (vi) Tenant shall be adjudicated
bankrupt or insolvent according to the law, or (vii) Tenant shall make any
assignment for the benefit of creditors, or (viii) Tenant shall file any
petition seeking a reorganization, arrangement or similar relief, or (ix) a
receiver, custodian, trustee or similar agent of the Premises or of all or a
substantial part of Tenant's assets shall be authorized or appointed, or (x)
Tenant's interest in this Lease is taken upon execution or other process of law
in any action against Tenant, then Landlord may lawfully enter the Premises and
repossess the same as the former estate of Landlord, or terminate this Lease and
the Term hereof upon five (5) day written notice to Tenant and, in either event,
expel Tenant and these claiming through or under Tenant, and remove their
effects (forcibly, if necessary), without being deemed guilty of any manner of
trespass and without prejudice to any other remedy which Landlord may have for
arrears of Basic Rent and other charges and sums due hereunder or proceeding on
account of breach of covenant, and upon entry or notice as aforesaid, this Lease
shall terminate. In case of any default by Tenant hereunder, Tenant shall pay
all costs of enforcing the Landlord's rights under this Lease (including,
without limitation, reasonable attorneys' fees and expenses). In addition,
following the termination of this Lease on account of such default as aforesaid,
Tenant shall pay damages, as Landlord may elect, equivalent to either (i) the
amount by which, at the termination of the Term of the Lease, the aggregate of
the Rent and other sums payable hereunder projected over a period from such
termination until the normal expiration date of the Term (specifically excluding
the extension period referenced in Section 2 unless Tenant shall have exercised
its option with respect thereto), exceeds the aggregate projected fair market
rental value of the Premises for such period, reasonably discounted in each case
to present value, or (ii)

                                     -26-
<PAGE>

an amount equal to the Rent and other sums which would have been payable had the
Lease not so terminated (subject to offset for net rents actually received from
reletting after subtraction of the reasonable expenses of reletting, Landlord
hereby agreeing to exercise good faith efforts to mitigate damages hereunder)
payable upon the due dates as specified herein, whichever the Landlord shall
elect.

     (b)  Landlord may bring legal proceedings for the recovery of such damages,
or any installments thereof, from time to time at its election, and nothing
contained herein shall be deemed to require Landlord to postpone suit until the
date when the Term of this Lease would have expired if it had not been
terminated hereunder.

     (c)  Nothing herein contained shall be construed as limiting or precluding
the recovery by Landlord from Tenant of any sums or damages (including, without
limitation, reasonable attorneys' fees and expenses) to which, in addition to
the damages particularly provided above, Landlord may lawfully be entitled by
reason of any default hereunder on the part of Tenant.  Landlord and Tenant
agree that, for the purpose of computing damages, the Tax Excess payments and
Operating Cost Excess payments for the period between the termination of the
Term of this Lease pursuant to this Section and the normal expiration date shall
be computed by multiplying the sum of the Tax Excess payment for the Fiscal Year
immediately preceding the Fiscal Year in which termination occurs and the
Operating Cost Excess payments for the year immediately preceding the year in
which termination occurs times the number of years and any fraction thereof
remaining of the full Term hereby granted on the assumption that the amount of
such Tax Excess payment and Operating Cost Excess payment for the immediately
preceding year would have remained constant for each subsequent year during the
full Term of this Lease.  If this Lease and the Term hereof shall terminate
pursuant to this Section prior to the determination of the initial Tax Excess
payment and Operating Costs the Tax Excess payment

                                     -27-
<PAGE>

and Operating Cost Excess payment shall be reasonably estimated by Landlord, in
its sole discretion, based on historical costs and experience.

     (d)  After more than two occasions during any consecutive twelve (12) month
period where payments of Rent, including additional rent, Tax Excess and
Operating Cost Excess and any other obligations of Tenant are not paid on the
date due, then such late payments shall, at the option of Landlord after notice
to Tenant, bear interest at the rate equal to the "prime rate" from time to time
established by BankBoston plus two percent (2%) per annum from the due date and
shall be compounded monthly.

     20.  Landlord's Right to Cure. If Tenant shall default in the observance or
          ------------------------
performance of any term, covenant or condition on its part to be observed or
performed under this Lease, Landlord, without being under any obligation to do
so and without thereby waiving such default, may remedy such default for the
account and at the expense of Tenant, immediately and without notice in case of
emergency, or in any other case, if Tenant shall fail to remedy such default
within the applicable grace period. If Landlord makes any expenditures or incurs
any obligations for the payment of money in connection therewith, including, but
not limited to, reasonable attorneys fees, such sums paid or obligations
incurred, with interest at the rate of interest set forth in Section 19, shall
be paid to Landlord by Tenant as Rent hereunder.

     21.  Subordination; Nondisturbance. (a) This Lease is subject and
          -----------------------------
subordinate in all respects to all mortgages and other existing matters of
record affecting the Building or the Property as of the date hereof. Tenant
agrees at the request of Landlord to subordinate this Lease to any mortgage,
ground lease, or other matter of record placed upon or affecting this Lease, the
Building, the Property or Landlord's interest or estate therein and to recognize
the holder thereof or any other person acquiring title to the Property as
Landlord, provided such holder or person

                                     -28-
<PAGE>

recognizes this Lease subject to a default by Tenant hereunder. Tenant agrees to
execute and deliver any appropriate instruments necessary to carry out the
foregoing provisions.

     (b)  Landlord agrees to use its diligent efforts to obtain from the current
holder of the first mortgage with respect to the Property (the "First Mortgage")
a nondisturbance agreement in such holder's usual form within ninety (90) days
from the date hereof, provided however that Tenant shall be required to pay any
charge customarily imposed by such holder therefor.

     22.  Surrender of Possession; Holdover. (a) At the expiration or earlier
          ---------------------------------
termination of the Term of this Lease, Tenant shall remove Tenant's Property and
shall peaceably yield up to Landlord the Premises in the condition required by
Section 10 (a), together with any Improvements (unless otherwise requested by
Landlord pursuant to the provisions of this Lease).

     (b)  If Tenant remains in the Premises beyond the expiration or earlier
termination of the Term of this Lease, such holding over shall not be deemed to
create any tenancy, but the Tenant shall be a Tenant-at-Sufferance only and
shall pay rent to Landlord at a daily rate in an amount equal to one and one
half times the daily rate of the Rent and other sums payable under this Lease as
of the last day of the Term of this Lease.

     23.  Notices. Any notice or demand by Tenant to Landlord shall be served by
          -------
registered or certified mail addressed to Landlord at the address first above
indicated, unless otherwise directed in writing by Landlord, and any notice or
demand by Landlord to Tenant shall be served by registered or certified mail, in
person, or by recognized overnight or other delivery service addressed to Tenant
at the address first above indicated until the Commencement Date and thereafter
the Premises, unless otherwise directed in writing by Tenant.  Any such notice
or demand shall be in writing and shall be deemed effective upon receipt or
refusal thereof.

     24.  Rules and Regulations. Tenant shall faithfully observe and comply with
          ---------------------
the Rules and Regulations set forth on Exhibit B attached hereto and made a part
hereof and such other and

                                     -29-
<PAGE>

further reasonable Rules and Regulations as Landlord hereafter at any time or
from time to time may make and may communicate in writing to Tenant at least
five (5) days before the effective date thereof and which apply to all other
tenants in the Building and which are commercially reasonable, which in the
judgment of Landlord shall be necessary for the reputation, safety, care or
appearance of the Building, or the preservation of good order therein, or the
operation or maintenance of the Building, or any equipment relating thereto, or
the comfort of tenants or others in the Building. Nothing contained in any such
Rules and Regulations shall be deemed to prohibit the hanging of customary
artwork, professional certificates and the like. If this Lease shall conflict
with any such Rules and Regulations, the provisions of this Lease shall control.
Landlord shall not have any duty or obligation to enforce the Rules and
Regulations or the terms, covenants or conditions in any other lease as against
any other tenant (so long as Landlord does not unreasonably discriminate among
tenants), and Landlord shall not be liable to Tenant for violation of such Rules
and Regulations, terms, covenants or conditions by other tenants, their
servants, employees, agents, visitors, invitees or licensees.

     25.  Quiet Enjoyment. The Tenant, on paying the Rent and other sums payable
          ---------------
hereunder and performing the covenants of this Lease on its part to be
performed, shall and may peaceably and quietly have, hold and enjoy the Premises
for the Term of this Lease.

     26.  Limitation of Landlord's Liability. The term "Landlord," as used in
          ----------------------------------
this Lease, so far as covenants or obligations to be performed by Landlord are
concerned, shall be limited to mean and include only the owner or owners at the
time in question of the Building, and in the event of any transfer or transfers
of title to said Building, the Landlord herein named (and in case of any
subsequent transfers or conveyances, the then grantor) shall be automatically
freed and relieved from and after the date of such transfer or conveyance of all
liability as respects the performance of any covenants or obligations on the
part of the Landlord contained in this Lease

                                     -30-
<PAGE>

thereafter to be performed, it being intended hereby that the covenants and
obligations contained in this Lease on the part of Landlord shall, subject as
aforesaid, be binding on the Landlord, its successors and assigns, only during
and in respect of their respective successive periods of ownership of the
Property. Tenant, its successors and assigns, agrees it shall not assert nor
seek to enforce any claim for breach of this Lease against any of Landlord's
assets other than Landlord's equity interest in the Building and in the rents,
issues and profits thereof (including the proceeds of any sale of such
interest), and Tenant agrees to look solely to such interest for the
satisfaction of any liability of or claim against Landlord under this Lease, it
being specifically agreed that in no event whatsoever shall Landlord (which term
shall include, without limitation, any beneficiary of any trust of which
Landlord is a trustee) ever be personally liable for any such liability.

     27.  Binding Agreement.  This Lease shall bind and inure to the benefit
          -----------------
of the parties hereto and such respective heirs, representatives, successors or
assigns as are permitted by this Lease. This Lease contains the entire agreement
of the parties and may not be modified except by an instrument in writing
executed by both Tenant and Landlord.

     28.  Notice of Lease.  Tenant agrees that it will not record this Lease.
          ---------------
Landlord and Tenant shall, upon request of either, execute and deliver a notice
of this Lease in such applicable form as may be permitted by applicable statute.

     29.  Brokerage. Landlord and Tenant each represents and warrants to the
          ---------
other that it has dealt with no broker except CB Richard Ellis - NE Partners, LP
and Avalon Partners, d/b/a CRESA Partners (the "Brokers"), in connection with
this transaction. Landlord hereby agrees to pay any compensation which may be
due by it to the Brokers. Tenant agrees to hold harmless and indemnify Landlord
from and against any and all cost, expense, or liability for any

                                     -31-
<PAGE>

compensation, commissions and charges claimed by any other broker or agent
claiming to have dealt with Tenant in connection with this Lease or the
negotiation thereof.

     30.   Guaranty. As used in clauses (iv), (v), (vi), (vii), (viii) and (ix)
           --------
of Section 19(a), the term "Tenant" shall also be deemed to refer to
any guarantor of Tenant's obligations hereunder.

     31.   Security Deposit. A deposit in the amount of $432,000 (the "Security
           ----------------
Deposit") shall be held by Landlord during the Term of this Lease as security
for the full, faithful and punctual performance of Tenant's covenants hereunder,
it being understood that the Security Deposit is not to be considered prepaid
rent, nor shall damages be limited to the amount of the Security Deposit, nor
shall Landlord be required, because of the Security Deposit, to waive its right
to terminate this Lease upon a default. The Security Deposit (if held in cash)
shall not earn interest and need not be kept in a segregated account or
otherwise escrowed. The Security Deposit, or any balance thereof, shall be
refunded to Tenant, subject to Tenant's satisfactory compliance herewith, within
thirty (30) days following the end of the Term of this Lease. Tenant shall be
entitled to pay the Security Deposit in the form of an irrevocable letter of
credit subject to the following terms and conditions. Said letter of credit
shall be issued by Silicon Valley Bank or any other commercial bank reasonably
acceptable to Landlord and shall be in a form reasonably satisfactory in all
respects to Landlord. In the event of any default by Tenant beyond the
applicable grace period, Landlord shall be entitled to receive from the issuer
of such letter of credit upon demand so much of the amount which may be drawn
therefrom as shall be necessary to cure such default and compensate Landlord for
all losses, liabilities, damages and other expenses, including without
limitation reasonable attorneys' fees, which may be imposed upon, incurred by or
asserted against Landlord by reason of such default, and Tenant shall thereafter
promptly restore such letter of credit to its original amount. If Tenant fails
to restore such letter

                                      -32
<PAGE>

of credit to its original amount as hereinabove required, or if such letter of
credit is about to expire and shall not have been renewed as herein required
within thirty (30) days preceding such expiration, then in any such event
Landlord may upon demand withdraw all remaining available funds under such
letter of credit and hold the same as a cash security deposit pursuant to the
preceding provisions of this Section. So long as Tenant is not then in default
hereunder and has not prior thereto been given written notice of any such
default on more than two (2) occasions during any twelve (12) month period, the
Security Deposit may be reduced to $216,000 effective as of the first day of the
31st full calendar month included in the Term of this Lease.

     32.   Environmental Provisions. Tenant shall not bring or permit to be
           ------------------------
brought or kept in or on the Premises or elsewhere on the Property any hazardous
materials, as such terms may be defined by any applicable federal, state or
local statute, ordinance, by-law, rule or regulation, including without
limitation the Massachusetts Oil and Hazardous Material Release Prevention and
Response Act (M.G.L. c. 21E), the Comprehensive Environmental Response,
Compensation and Liability Act, as amended (42 U.S.C. (S)(S)9601 et seq.), and
the Resource Conservation and Recovery Act, as amended (42 U.S.C. (S)(S)6901 et
seq.), but excluding cleaning supplies and other products typically used by
tenants of office space, so long as such products are commercially packaged and
properly stored and handled. Landlord shall be responsible for the remediation,
if and as required by applicable law, of any such hazardous materials present on
the Property other than on account of Tenant's failure to comply with the
provisions of this Section.

     33.   General Provisions. (a) The various rights and remedies contained in
           ------------------
this Lease and reserved to each of the parties shall not be exclusive of any
other right or remedy of such party, but shall be construed as cumulative and
shall be in addition to every other remedy now or hereafter existing at law, in
equity, or by statute. No delay or omission of the right to exercise any power
by either party shall impair any such right or power, or shall be construed as a
waiver

                                     -33-
<PAGE>

of any default or as acquiescence in any default. One or more waivers of
any covenant, term or condition of this Lease by either party shall not be
construed by the other party as a waiver of a subsequent breach of the same
covenants, terms or conditions. The consent or approval of either party to or of
any act by the other party of a nature requiring consent or approval shall not
be deemed to waive or render unnecessary consent to or approval of any
subsequent similar act.

     (b)   Where the words "Landlord" and "Tenant" are used in this Lease, they
shall include Landlord and Tenant and shall apply to persons, both men and
women, associations, partnerships and corporations, and in reading this Lease
the necessary grammatical changes required to make the provisions hereof mean
and apply to them shall be made in the same manner as if written into the Lease.

solely upon the statements contained in this Lease and fully understands that no
agents or representatives of Landlord have authority to in any manner change,
add to or detract from the terms of this Lease.

     (c)   Tenant hereby declares that in entering into this Lease, Tenant
relied solely upon the statements contained in this Lease and fully understands
that no agents or representatives of Landlord have authority to in any manner
change, add to or detract from the terms of this Lease.

     (d)   The invalidity of one or more of the provisions of this Lease shall
not affect the remaining portions of this Lease; and, if any one or more of the
provisions of this Lease should be declared invalid by final order, decree or
judgment of a court of competent jurisdiction, this Lease shall be construed as
if such invalid provisions had not been included in this Lease.

     (e)   If Tenant shall be two or more persons or entities, each such person
or entity shall be jointly and severally liable for the payment of all sums due
to Landlord from Tenant under this Lease and the performance of all of Tenant's
covenants, agreements, or obligations under this Lease.

     (f)   The submission of this Lease for examination or its negotiation or
the negotiation of the transaction described herein does not constitute a final
agreement to lease, and the execution of this Lease by Tenant does not
constitute a binding contract until such time as this

                                     -34-
<PAGE>

Lease has been approved by the First Mortgagee. Landlord shall use good faith
efforts to promptly obtain such consent.

     (g)   In the event this Lease is in full force and effect without default
by Tenant, Landlord shall use reasonable efforts to notify Tenant of any space
in the Building which Landlord wishes to lease other than to the current tenant
or occupant thereof (if any). In no event shall the foregoing provisions be
construed as an option, right of first refusal or other entitlement to lease
such space, nor shall Landlord be obligated to make any concession to Tenant in
order to facilitate such leasing.

     (h)   In no event shall either party be liable to the other for indirect or
consequential damages.

     Executed as a sealed instrument as of the date first above written by the
duly authorized representatives of Landlord and Tenant.

     WHEREAS, pursuant to an existing lease agreement between the parties dated
June 17, 1999 (hereinafter referred to as the "Lease"), Landlord has leased to
Tenant certain Premises contained in the Building known and numbered as 711
Atlantic Avenue, Boston, Massachusetts, all as more particularly described and
set forth in the Lease; and

     WHEREAS, Landlord and Tenant wish to provide for the expansion of the
Premises, subject to the provisions hereof;

     NOW THEREFORE, in consideration of the foregoing recitals and for further
good and valuable consideration, the receipt and adequacy whereof are hereby
acknowledged, Landlord and Tenant do hereby agree as follows:

conditions and provisions of the Lease except as otherwise set forth herein.

     2.   The Commencement Date applicable to the Expansion Area shall be the
date (hereinafter referred to as the "Delivery Date") on which Landlord delivers
possession of said Area to Tenant broom clean and free and clear of other
tenants and occupants, any furniture or other personal property having been
removed. The Term of the Lease with respect to the Expansion Area shall end at
the same time as the Term of the Lease applicable to the remainder of the
Premises.

     3.   Subject to Landlord's repair obligations under the Lease, Tenant shall
accept the Expansion Area "as is", in its existing condition as of the Delivery

attached hereto as Exhibit A and made a part hereof and agreed to contain 575
square feet of rentable area (hereinafter referred to as the "Expansion Area")
shall be added to the Premises subject to all terms, covenants, conditions and
provisions of the Lease except as otherwise set forth herein.

     2. The Commencement Date applicable to the Expansion Area shall be the date
(hereinafter referred to as the "Delivery Date") on which Landlord delivers
possession of said Area to Tenant broom clean and free and clear of other
tenants and occupants, any furniture or other personal property having been
removed. The Term of the Lease with respect to the Expansion Area shall end at
the same time as the Term of the Lease applicable to the remainder of the
Premises.
<PAGE>

     3. Subject to Landlord's repair obligations under the Lease, Tenant shall
accept the Expansion Area "as is", in its existing condition as of the Delivery
Date, and all work necessary to prepare the Expansion Area for occupancy
(including without limitation the reconfiguration of demising walls wherever
necessary to separate the Premises from adjoining areas of the Building) shall
be performed by Tenant in accordance with Section 8 and the other applicable
provisions of the Lease.

     4. Tenant shall pay to Landlord Basic Rent with respect to the Expansion
Area at the rate of $18,400.08 per annum, payable in equal monthly installments
of $1,533.34 each as generally set forth in the Lease. Notwithstanding the
foregoing, no such installments shall be due with respect to the period prior to
the date on which Basic Rent first becomes payable with respect to the adjoining
portion of the Premises on the fourth (4th) floor of the Building.

     5. The percentage applicable to the calculation of the Operating Cost
Excess and the Tax Excess shall be 0.722% in the case of the Expansion Area.

     6. At Landlord's option, electrical energy may be supplied to the Expansion
Area in common with other rentable area in the Building, in which case, in lieu
of purchasing such electrical energy directly from the public utility company
servicing the Building, Tenant shall pay to Landlord, from time to time upon
billing, a proportionate share of all charges for such electrical energy
computed on the basis of the ratio between the rentable area of the Expansion
Area and the rentable area (consistently measured) of the portion of the
Building serviced by the same electrical meter which services the Expansion Area
(hereinafter referred to as the "Service Area"). Such payment shall be prorated
to exclude any period not included within the Term of the Lease applicable to
the Expansion Area and shall be equitably adjusted if any portion of the Service
Area other than the Expansion Area is not occupied at any time during the
relevant

                                      -2-

billing period. Any electrical energy charges of which Tenant is obligated to
pay a share pursuant to the foregoing provisions shall not be included as part
of Operating Costs.

     7.   Unless the context requires otherwise, the terms used herein shall be
construed in conformity with the definitions set forth in the Lease.

     8.   Except as herein modified, the Lease is hereby ratified and confirmed.
IN WITNESS WHEREOF, Landlord and Tenant have caused this instrument to be
executed under seal as of the day and year first above written.
