     Two-page design with "Internet" in large lettering across the top of both
pages. Upper left corner of the graphic's left page contains the statement "what
makes us different". Directly beneath this statement is the following paragraph:
 
             In 1994, Proxicom developed some of the first Internet
        commerce storefronts and discovered the key to successful
        Internet solutions -- a seamless integration of strategy,
        technology and creative design skills. Proxicom has continued to
        grow these traditionally disparate talents within an iterative
        process that shares best practices and incorporates industry
        expertise. The result is a culture where people work together to
        create innovative Internet solutions that improve business
        processes and create new business opportunities.
 
     The phrase "Integrated Internet Skills" is beneath this paragraph. A circle
with three pegs and the words "strategy", "technology" and "creative design" is
contained in the lower half of the left page.
 
     The upper half of the graphic's right page contains a pyramid with five
levels. A level of the pyramid corresponds to each of the following items:
 
     -  Value Through Innovation
          Creating innovative Internet solutions for our clients
 
     -  Proxicom Process(SM)
          Speed, Quality and Reduced Risk
 
     -  Internet Best Practices
          Sharing our collective Internet knowledge since 1994
 
     -  Industry Expertise
          Internet focus with industry specific knowledge
 
     -  Integrated Skills
          Strategy, Technology and Creative Design
 
     Proxicom's logo is in the lower right corner of this page.
 
FRONT COVER GRAPHIC:
 
     Contains pictures and descriptions of projects Proxicom has completed for
three clients, Calphalon, the American Electronics Association ("AEA") and GE
Plastics. This page is separated into three rows. The first row contains the
boxed word "Internet", a picture of the web site Proxicom designed for
Calphalon, and the following description of the work Proxicom performed for
Calphalon as well as the benefits Calphalon derived as a result:
 
        CALPHALON
 
        Business-to-Consumer Internet Commerce
 
             Calphalon sought to launch a new site to fully exploit the
        interactive potential of the Internet. Proxicom created a
        solution for Calphalon that differentiates its offerings in
        cookware products by uniting a complement of communications,
        content and transaction capabilities through a single source.
        The solution includes information for consumers, Calphalon's
        full portfolio of product information, educational instructions,
        a database of recipes and interactive capabilities. Calphalon
        established a direct link with a new audience of prospective
        customers, gaining invaluable knowledge of their interests. The
        site also provides Calphalon with the ability to influence and
        flexibly respond to market needs. Proxicom also created the
        solutions branding and user interface
<PAGE>   4
 
        to enhance Calphalon's marketing presence. The solution has
        created efficiencies for Calphalon's business and has been used
        to introduce a new line of cutlery products to test market
        acceptance.
 
     The second row contains the boxed word "Extranet" a picture of the extranet
Proxicom designed for AEA, and the following description of the work Proxicom
performed for AEA as well as the benefits AEA derived as a result:
 
        AMERICAN ELECTRONICS ASSOCIATION
 
        A New Internet-Based Membership Service
 
             The American Electronics Association ("AEA"), the largest
        high-tech trade association with over 3,000 member companies
        nationwide such as Intel Corporation, Amazon.com and Yahoo!
        Inc., sought to leverage the Internet to improve its business.
        AEA wanted to transform the way it worked with its members, an
        initiative central to AEA's strategic plans. Proxicom is
        repositioning AEA, re-branding the company and creating a new
        online membership service. The functional and dynamic extranet
        Proxicom created ties into AEA's core systems enabling
        distributed authoring and release of content as well as
        personalization of information for its users. It will also
        permit the sale of AEA products and services with real-time
        pricing. The solution will redefine how AEA markets, increasing
        sales, making publishing more efficient and establishing direct
        communication with members and industry experts.
 
     The third row contains the boxed word "Intranet", a picture of the intranet
Proxicom designed for GE Plastics and the following description of the work
Proxicom performed for GE Plastics as well as the benefits GE Plastics derived
as a result:
 
        GE PLASTICS
 
        Intranet Knowledge Management System
 
             The employees at GE Plastics were faced with time-consuming
        searches for marketing, technical, sales and customer service
        information stored in decentralized databases, file systems and
        non-networked PCs. Proxicom changed that by helping GE Plastics
        transform its knowledge management and customer care tracking
        systems through a company-wide, knowledge management Intranet.
        The solution eliminated costly time spent searching for
        information and provided the marketing, sales, IT and customer
        service personnel with a valuable decision making tool that has
        helped them dramatically improve their effectiveness and
        successfully increase productivity.

                               PROSPECTUS SUMMARY
 
     You should read the following summary together with the more detailed
information and the financial statements and notes to those financial statements
which appear elsewhere in this prospectus.
 
                                 PROXICOM, INC.
 
OUR BUSINESS
 
     Proxicom is a leading provider of Internet solutions to Global 1000
companies and other large organizations. Since 1994, we have focused exclusively
on the Internet and have successfully completed over 600 client engagements. As
of December 31, 1998, we had a total of approximately 150 ongoing client
engagements.
 
     In all of our client engagements we apply the Proxicom Process, a four-step
methodology that we use to deliver Internet solutions. Using the Proxicom
Process, we integrate strategy, technology and creative design to help our
clients transform their businesses with Internet solutions.
 
     We sell and deliver our services and expertise through teams organized into
four industry groups, or vertical markets:
 
     -  energy and telecommunications;
 
     -  financial services;
 
     -  retail and manufacturing; and
 
     -  service industries.
 
This structure allows us to build industry expertise, develop market-specific
solutions for clients and replicate business solutions across client
engagements.
 
     Our Internet solutions have included
 
     -  business to consumer electronic commerce Internet sites for Calphalon
        Corporation, Cox Interactive Media, Inc. and Owens Corning, enabling
        these clients to provide information about and sell products to
        consumers;
 
     -  business to business electronic commerce extranets for the American
        Electronics Association, Mercedes-Benz Credit Corp. and McKessonHBOC,
        enabling these clients to transact business with other businesses; and
 
     -  company-specific intranets for GE Plastics, Hoffmann-La Roche, Inc. and
        Merrill Lynch & Co., Inc., enabling persons within these organizations
        to exchange information electronically.
 
OUR MARKET OPPORTUNITY
 
     The Internet presents opportunities to transform businesses and entire
industries. Companies use the Internet to
 
     -  communicate and transact business on a one-to-one basis with existing
        customers;
 
     -  target and acquire new customers;
 
     -  collaborate with their supply-chain partners;
 
     -  enable electronic commerce; and
 
     -  manage distribution relationships.
 
                                        1
<PAGE>   6
 
The Internet has also allowed businesses to identify new product and service
offerings which extend and complement their core markets. As a result,
organizations invest in Internet solutions to transform their core business and
technology strategies.
 
     These opportunities are creating a significant and growing demand for
third-party Internet professional services. International Data Corp., a
technology industry research firm, forecasts that the market for Internet and
electronic commerce services worldwide will grow from $4.6 billion in 1997 to
$43.7 billion by 2002. Forrester Research, Inc., another technology industry
research firm, estimates the market for Internet and electronic commerce
services will grow from $5.4 billion in 1998 to $32.7 billion by 2002. These
projections represent a compound annual growth rate of more than 55% over these
periods. Forrester Research predicts that the Internet will be one of the
fastest growing areas within the information technology services industry.
 
     Proxicom believes organizations are increasingly searching for a
single-source professional services firm that can deliver integrated strategy,
technology and creative design skills specifically for the Internet.
 
OUR STRATEGY
 
     Our strategy is to build upon our position as a leading Internet solutions
provider. To do this, we plan to
 
     -  leverage existing client relationships;
 
     -  further penetrate our vertical markets;
 
     -  continue geographic expansion;
 
     -  hire and retain skilled professionals;
 
     -  evolve the Proxicom Process;
 
     -  leverage technology partnerships; and
 
     -  extend reusable solutions.
 
     We service our engagements with multi-disciplinary teams that work as
cohesive units. We facilitate collaboration among the client's business,
information technology and marketing functions. We believe our coordinated
approach results in better Internet solutions.
 
OUR OFFICES AND HISTORY
 
     We started our business in 1991 as a Maryland corporation. We reorganized
as a Delaware corporation in 1996. Our principal offices are located at 11600
Sunrise Valley Drive in Reston, VA 20191. Our telephone number is 703-262-3200.

                                  RISK FACTORS
 
     An investment in our common stock involves risks. You should carefully
consider the risks described below and the other information in this prospectus
including our financial statements and the related notes before you decide to
buy our common stock. The trading price of our common stock could decline due to
any of these risks, and you could lose all or part of your investment.
 
WE ARE GROWING QUICKLY. FUTURE GROWTH OF OUR BUSINESS COULD MAKE IT DIFFICULT TO
MANAGE OUR RESOURCES.
 
     Our business is growing substantially, both through increased sales and
recent acquisitions. For instance, our sales have increased from $1.3 million in
1994 to $42.4 million in 1998. Our rapid growth has stretched, and could
continue to stretch, our resources. We expect that we will need to continue to
hire and retain management personnel and other employees. Our management has
limited experience managing a business of Proxicom's size or a public company.
 
     In order to manage our growth effectively, we must establish offices in new
geographic locations, set fixed-price fees accurately, maintain high employee
utilization rates and maintain project quality, particularly if the average size
of our projects continues to increase.
 
     Our performance may depend on the effective integration of acquired
businesses. This integration, even if successful, may be expensive and time
consuming and could strain our resources.
 
WE MAY NOT BE ABLE TO HIRE AND RETAIN HIGHLY SKILLED EMPLOYEES, WHICH COULD
AFFECT OUR ABILITY TO COMPETE EFFECTIVELY.
 
     To succeed, we must hire, train, motivate, retain and manage employees who
are highly skilled in the Internet and its rapidly changing technology. Because
of the recent and rapid growth of the Internet, individuals who have Internet
expertise and can perform the services we offer are scarce. Competition for
these individuals, therefore, is intense. We might not be able to hire enough of
them or to train, motivate, retain and manage the employees we do hire. This
could hinder our ability to complete existing projects and bid for new projects.
In addition, because the competition for qualified employees in the Internet
industry is intense, hiring, training, motivating, retaining and managing
employees with the strategic, technical and creative skills we need is both
time-consuming and expensive.
 
WE HAVE LOST MONEY IN THREE OF THE LAST FOUR QUARTERS AND COULD LOSE MONEY IN
THE FUTURE BECAUSE PROJECTS MAY BE DELAYED OR CANCELLED.
 
     Our financial results may fluctuate from quarter to quarter. In fact, we
have incurred operating losses in three of our last four quarters. In future
quarters, our operating results may not meet public market analysts' and
investors' expectations. If that happens, the price of our common stock may
fall. Many factors can cause these fluctuations, including
 
     -  the number, size, timing and scope of our projects;
 
     -  customer concentration;
 
     -  long and unpredictable sales cycles;
 
     -  contract terms of projects;
 
     -  degrees of completion of projects;
 
     -  project delays or cancellations;
 
     -  competition for and utilization of employees;
 
     -  how well we estimate the resources we need to complete projects;
 
     -  the integration of acquired businesses;
 
     -  pricing changes in the industry; and
 
                                        5
<PAGE>   10
 
     -  economic conditions specific to the Internet and information technology
        consulting.
 
     A high percentage of our operating expenses, particularly personnel and
rent, are fixed in advance of any particular quarter. As a result, if we
experience unanticipated changes in our projects or in our employee utilization
rates, we could experience large variations in quarterly operating results and
losses in any particular quarter. Due to these factors, we believe you should
not compare our quarter-to-quarter operating results to predict our future
performance.
 
     We have generally realized lower revenue in the first quarter of the year
than in the other quarters. We believe that this has been due primarily to
client budget cycles and the short-term nature of our contracts.
 
WE FAILED TO GENERATE CASH FROM OPERATIONS DURING 1996 AND 1998 AND COULD FAIL
TO GENERATE CASH FROM OPERATIONS IN THE FUTURE.
 
     We did not generate cash from operations in these years largely due to the
expansion of our business. Particularly in 1998, we increased our number of
Internet solutions professionals and support personnel. We also incurred
expenses in connection with mergers. We plan to continue to expand and develop
our business, both internally and possibly through future acquisitions. This
could cause us to fail to generate cash from operations in the future.
 
WE HAVE A NUMBER OF SIGNIFICANT CLIENTS. IF WE LOSE A MAJOR CLIENT OR
SIGNIFICANT PROJECT, OUR REVENUES COULD BE ADVERSELY AFFECTED.
 
     We generate much of our revenue from a limited number of major clients. As
a result, if we lose a major client or large project, our revenues could be
adversely affected. In 1998, for example, our two largest clients, Pacific Gas
and Electric Company and General Electric Company, accounted for approximately
15% and 14%, respectively, of our revenue. That year, our five largest clients
contributed approximately 38% of our revenue. In 1997, our two largest clients,
Pacific Gas and Electric Company and General Electric Company, accounted for
approximately 24% and 10%, respectively, of our revenue. Our five largest
clients contributed approximately 48% of our revenue in that year.
 
     We perform varying amounts of work for specific clients from year to year.
A major client in one year may not use our services in another year. In
addition, we may derive revenue from a major client that constitutes a large
portion of a particular quarter's total revenue. If we lose any major clients or
any of our clients cancel or significantly reduce a large project's scope, our
business, financial condition and results of operations could be materially and
adversely affected. Also, if we fail to collect a large account receivable, we
could be subjected to significant financial exposure.
 
WE HAVE MANY SHORT-TERM CONTRACTS THAT CAN BE CANCELLED WITHOUT PENALTY. IF
CLIENTS TERMINATE CONTRACTS WITH US ON SHORT NOTICE, OUR RESULTS OF OPERATIONS
COULD SUFFER.
 
     Our contracts with clients are generally short-term. Also, most clients can
reduce or cancel their contracts for our services without penalty and with
little or no notice. If a significant client or a number of small clients
terminate, significantly reduce or modify business relationships with us, our
business, financial condition and results of operations could be materially and
adversely affected. Consequently, you should not predict or anticipate our
future revenue based on the number of clients we have or the number and size of
our existing projects. When a client postpones, modifies or cancels a project,
we have to shift our employees to other projects and minimize the resulting
adverse impact on our operating results. In addition, our operating expenses are
relatively fixed and cannot be reduced on short notice.
 
IF WE FAIL TO MEET OUR CLIENTS' EXPECTATIONS, WE COULD DAMAGE OUR REPUTATION AND
HAVE DIFFICULTY ATTRACTING NEW BUSINESS.
 
     Many of our projects are complex and critical to our clients. As a result,
if we fail or are unable to meet a client's expectations, we could damage our
reputation. This could adversely
 
                                        6
<PAGE>   11
 
affect our ability to attract new business from that client or others. If we
fail to perform adequately on a project, a client could sue us for economic
damages.
 
WE COULD LOSE MONEY ON OUR CONTRACTS.
 
     As part of our strategy, we generally enter into fixed-price,
fixed-timeframe contracts, rather than contracts based on payment for time and
materials. Often, we fix the price or timeframe before we finalize the design
specifications. If we miscalculate the resources or time we need for these
projects, our business, financial condition and results of operations could be
materially and adversely affected.
 
WE MAY NOT COMPETE SUCCESSFULLY WITH OUR COMPETITORS, WHICH COULD RESULT IN
REDUCED REVENUES.
 
     We compete in markets that are new, intensely competitive and rapidly
changing. We may not compete successfully with our competitors. We currently
compete for client assignments and experienced personnel principally with the
following:
 
     -  large systems integrators such as International Business Machines
        Corporation, Andersen Consulting and Computer Sciences Corporation;
 
     -  specialty systems integrators such as Cambridge Technology Partners,
        Inc. and Sapient Corporation;
 
     -  strategy consulting firms such as McKinsey & Company, Inc. and Boston
        Consulting Group, Inc.; and
 
     -  Internet professional services providers such as USWeb/CKS, Viant
        Corporation, Scient Corporation and iXL Enterprises, Inc.
 
Many of these businesses have longer operating histories and significantly
greater financial, technical, marketing and managerial resources than we do.
International Business Machines Corporation, Andersen Consulting and Computer
Sciences Corporation have much longer operating histories, generate much greater
revenue and are better known than we are. Cambridge Technology Partners, Inc.
and Sapient Corporation generate significantly more revenue than we do. McKinsey
& Company, Inc. and Boston Consulting Group, Inc. offer a greater breadth of
management consulting services and have a much longer operating history than we
do.
 
     Our markets have relatively low barriers to entry. We expect to continue to
face competition from new market entrants, including interactive marketing firms
such as Agency.com, Ltd. and Modern Media.PoppeTyson, Inc.
 
     Competition in our market is based primarily on the following factors:
 
     -  Internet expertise and talent;
 
     -  quality, pricing and speed of service delivery;
 
     -  client references;
 
     -  integrated strategy, technology and creative design services; and
 
     -  vertical industry knowledge.
 
     Some competitive factors are outside of our control. These factors include
our competitors' hiring and retention of senior staff, development of software
that is competitive with our products and services and response to client needs.
 
LACK OF GROWTH OR DECLINE IN INTERNET USAGE COULD CAUSE OUR BUSINESS TO SUFFER.
 
     We have derived most of our revenue from projects involving the Internet.
The Internet is new and rapidly evolving. Our business will be adversely
affected if Internet usage does not continue to grow. A number of factors may
inhibit Internet usage. These factors include inadequate network infrastructure,
security concerns, inconsistent service quality and lack of cost-effective,
high-speed service. On the other hand, if Internet usage grows, the Internet
 
                                        7
<PAGE>   12
 
infrastructure may not support the demands this growth will place on it. The
Internet's performance and reliability may decline. In addition, outages and
delays have occurred throughout the Internet network infrastructure and have
interrupted Internet service. If these outages or delays occur frequently in the
future, Internet usage could grow more slowly or decline.
 
     We may also incur substantial costs to keep up with changes surrounding the
Internet. Unresolved critical issues concerning the commercial use and
government regulation of the Internet include the following:
 
     -  security;
 
     -  cost and ease of Internet access;
 
     -  intellectual property ownership;
 
     -  privacy;
 
     -  taxation; and
 
     -  liability issues.
 
Any costs we incur because of these factors could materially and adversely
affect our business, financial condition and results of operations.
 
IF WE FAIL TO KEEP PACE WITH CHANGING TECHNOLOGIES, WE MAY LOSE CLIENTS.
 
     Our market is characterized by rapidly changing technologies, frequent new
product and service introductions and evolving industry standards. If we cannot
keep pace with these changes, our business could suffer. The Internet's recent
growth and intense competition in our industry exacerbate these characteristics.
To achieve our goals, we need to develop strategic business and Internet
solutions that keep pace with continuing changes in industry standards,
information technology and client preferences. We will have to improve the
performance features and reliability of our services to adapt to rapidly
changing technologies. Also, as part of our business strategy, we reuse elements
of our Internet solutions for which there is repeat customer demand. We could
incur substantial costs if we need to modify our reusable solutions to adapt to
technological changes.
 
IF WE LOSE THE SERVICES OF OUR FOUNDER, CHAIRMAN AND CHIEF EXECUTIVE OFFICER
RAUL J. FERNANDEZ, OR OTHER KEY PERSONNEL, OUR BUSINESS AND STOCK PRICE COULD
SUFFER.
 
     Our future success depends in large part on the continued services of a
number of our key personnel, including our founder, Chairman, President and
Chief Executive Officer, Raul J. Fernandez. We have no employment contract with
Mr. Fernandez or many of our other key personnel. The loss of the services of
Mr. Fernandez or any of our other key personnel could have a material adverse
effect on our business, financial condition and results of operations. We might
not be able to prevent key personnel, who may leave our employ in the future,
from disclosing or using our technical knowledge, practices or procedures. One
or more of our key personnel might resign and join a competitor or form a
competing company. As a result, we might lose existing or potential clients.
 
WE DEPEND ON INTELLECTUAL PROPERTY WHICH MAY BE DIFFICULT TO PROTECT. THIS COULD
AFFECT OUR ABILITY TO COMPETE EFFECTIVELY.
 
     Our success depends, in part, upon our intellectual property rights. We do
not have any patents or patent applications pending. Existing trade secret and
copyright laws afford us only limited protection. Third parties may attempt to
disclose, obtain or use our solutions or technologies. This is particularly true
in foreign countries where laws or law enforcement practices may not protect our
proprietary rights as fully as in the United States. Others may independently
develop and obtain patents or copyrights for technologies that are similar or
superior to our technologies. If that happens, we may not be able to license
those technologies on reasonable terms, or at all.
 
                                        8
<PAGE>   13
 
     Generally, we develop software applications for specific client
engagements. We generally assign software ownership to the client and retain
only a license for limited uses. Issues relating to ownership of and rights to
use software applications and frameworks can be complicated. We may become
involved in disputes that affect our ability to resell or reuse these
applications and frameworks. Also, we may have to pay economic damages in these
disputes.
 
WE ARE, AND WILL CONTINUE TO BE, CONTROLLED BY OUR OFFICERS AND DIRECTORS, WHICH
COULD RESULT IN OUR TAKING ACTIONS THAT OTHER STOCKHOLDERS DO NOT APPROVE.
 
     When this offering closes, our directors and executive officers will
beneficially own approximately 61% of the outstanding common stock. As a result,
they will continue to be able to control most matters requiring stockholder
approval. Among other things, they will be able to elect a majority of the
directors and approve significant corporate matters.
 
PROBLEMS RELATED TO THE YEAR 2000 ISSUE COULD REQUIRE US TO INCUR UNANTICIPATED
DELAYS AND EXPENSES.
 
     Year 2000 problems could require us to incur delays and unanticipated
expenses. These delays and expenses could have a material adverse effect on our
business, financial condition and results of operations. Clients' and potential
clients' purchasing patterns may be affected by year 2000 issues as companies
expend significant resources to correct or replace their current systems for
year 2000 compliance. These clients and potential clients may have fewer funds
available to purchase our services. We may experience operations difficulties
because of undetected errors or defects in the technology we use in our internal
systems. We have made representations to clients concerning year 2000 compliance
and may become involved in disputes regarding year 2000 problems involving
solutions that we have developed or implemented. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Year 2000
Readiness Disclosure."
 
FUTURE ACQUISITIONS OR INVESTMENTS COULD DISRUPT OUR ONGOING BUSINESS, DISTRACT
OUR MANAGEMENT AND EMPLOYEES, INCREASE OUR EXPENSES AND ADVERSELY AFFECT OUR
RESULTS OF OPERATIONS.
 
     We have made three acquisitions and agreed to an investment in a joint
venture in the last 15 months. Any acquisitions or investments we make in the
future will involve risks. We may not be able to make acquisitions or
investments on commercially acceptable terms. If we do buy a company, we could
have difficulty retaining and assimilating that company's personnel. In
addition, we could have difficulty assimilating acquired products, services or
technologies into our operations. These difficulties could disrupt our ongoing
business, distract our management and employees, increase our expenses and
materially and adversely affect our results of operations. Furthermore, we may
incur debt or issue equity securities to pay for any future acquisitions. If we
issue equity securities, your ownership share of Proxicom could be reduced.
 
WE HAVE STARTED EXPANDING OUR BUSINESS OVERSEAS. OUR INTERNATIONAL EXPANSION
COULD RESULT IN FINANCIAL LOSSES DUE TO CHANGES IN FOREIGN ECONOMIC CONDITIONS
AS WELL AS FLUCTUATIONS IN CURRENCY AND EXCHANGE RATES.
 
     We expect to expand our international operations and international sales
and marketing efforts. Recently, we commenced operations in Germany and began
servicing clients in Spain. We also plan to service clients in Italy soon. We
have limited experience in marketing, selling and distributing our services
internationally. International operations are subject to other inherent risks,
including the following:
 
     -  recessions in foreign economies;
 
     -  political and economic instability;
 
     -  fluctuations in currency exchange rates;
 
     -  difficulties and costs of staffing and managing foreign operations;
 
                                        9
<PAGE>   14
 
     -  potentially adverse tax consequences;
 
     -  reduced protection for intellectual property rights in some countries;
 
     -  changes in regulatory requirements; and
 
     -  reductions in business activity during the summer months in Europe.
 
THIS OFFERING'S NET PROCEEDS MAY BE ALLOCATED IN WAYS WITH WHICH YOU AND OTHER
STOCKHOLDERS MAY NOT AGREE.
 
     We have not determined how the majority of the proceeds of this offering
will be spent. Our management may spend this offering's net proceeds in ways
with which you and our other stockholders may not agree. See "Use of Proceeds."
 
THE TOTAL PRICE INVESTORS WILL PAY FOR OUR COMMON STOCK IN THIS OFFERING WILL
SUBSTANTIALLY EXCEED THE VALUE OF OUR ASSETS AFTER SUBTRACTING OUR LIABILITIES.
 
   
     The price you will pay for our common stock will be substantially higher
than the book value per share of our outstanding stock after this offering. In
addition, investors in this offering will contribute 69.9% of the total amount
paid by all investors in our company but will own only 16.9% of the shares
outstanding.
    
 
OUR STOCK HAS NOT TRADED PUBLICLY, AND AFTER THIS OFFERING ITS MARKET PRICE MAY
FLUCTUATE WIDELY.
 
     Prior to this offering, there has been no public market for our common
stock. The market price of our common stock could fluctuate substantially due to
 
     -  future announcements concerning us or our competitors;
 
     -  quarterly fluctuations in operating results;
 
     -  announcements of acquisitions or technological innovations; or
 
     -  changes in earnings estimates or recommendations by analysts.
 
In addition, the stock prices of many technology companies fluctuate widely for
reasons which may be unrelated to operating results. Fluctuations in our common
stock's market price may affect our visibility and credibility in the Internet
solutions market.
 
THE PRICE PER SHARE OF OUR COMMON STOCK IN THIS OFFERING MAY NOT BE INDICATIVE
OF THE MARKET PRICE THAT WILL PREVAIL AFTER THIS OFFERING.
 
     Since our stock has not yet traded publicly, our management and the
underwriters will negotiate the common stock's initial public offering price per
share. The price they determine may not be indicative of the market price that
will prevail after this offering. As a result, you could suffer a loss if the
market price that prevails after this offering is less than the price you paid
per share.
 
FUTURE SALES OF OUR COMMON STOCK IN THE PUBLIC MARKET COULD LOWER OUR STOCK
PRICE AND IMPAIR OUR ABILITY TO RAISE FUNDS IN NEW STOCK OFFERINGS.
 
   
     After this offering and a recently completed acquisition, we will have
23,901,103 shares of common stock outstanding. If the underwriters exercise
their over-allotment option in full, we will have 24,576,103 shares outstanding.
Sales of a large number of shares could adversely affect the market price of our
common stock and could impair our ability to raise funds in additional stock
offerings.
    
 
     The shares of common stock sold in this offering will be freely tradable
without restriction or further registration under the Securities Act, unless the
shares are purchased by an affiliate of ours, sales of which will be limited by
Rule 144 under the Securities Act. Holders of restricted shares generally will
be entitled to sell these shares in the public market without registration
either under Rule 144 or any other applicable exemption under the Securities
Act.
 
                                       10
<PAGE>   15
 
     As soon as practicable after this offering we intend to register up to
8,350,000 shares of common stock subject to outstanding stock options or
reserved for issuance under our stock plans. As of March 26, 1999, options to
purchase 4,977,347 shares of common stock were outstanding.
 
     In addition, upon completion of this offering, the holders of 19,056,133
shares of common stock have the right to request registration of these shares in
future public offerings of our equity securities.
 
IT MAY BE HARD FOR A THIRD PARTY TO ACQUIRE OUR COMPANY, AND THIS COULD DEPRESS
OUR STOCK PRICE.
 
     Provisions of our certificate of incorporation, our bylaws and Delaware law
could make it difficult for a third party to acquire us, even if doing so would
benefit our stockholders. This could depress our stock price.
 
OUR BOARD OF DIRECTORS CAN ISSUE PREFERRED STOCK WITH RIGHTS ADVERSE TO THE
HOLDERS OF COMMON STOCK.
 
     After the offering, our board of directors will be authorized, without
further stockholder approval, to issue up to 10,000,000 shares of preferred
stock. Issuance of preferred shares with rights to distributions, voting rights
or other rights superior to the common stock would be adverse to the holders of
common stock. See "Description of Capital Stock."
 
YOU SHOULD NOT EXPECT TO RECEIVE DIVIDENDS FROM US.
 
     We do not expect to declare or pay any cash dividends in the foreseeable
future.
 
YOU SHOULD BE AWARE THAT THERE ARE BENEFITS OF THE OFFERING TO EXISTING
STOCKHOLDERS.
 
   
     Several of our stockholders are selling shares in this offering. As
calculated under "Dilution," the average price per share paid by our existing
stockholders is $1.19. The net price per share paid to the selling stockholders
in this offering is $12.56. Therefore, the average realized gain per share to
the selling stockholders is $11.37. See "Dilution."
    
 
THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS WHICH MAY NOT PROVE TO BE
ACCURATE.
 
     This prospectus contains forward-looking statements. The outcome of the
events described in these forward-looking statements is subject to risks. Actual
results could differ materially. This "Risk Factors" section and those sections
entitled "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Business" as well as other sections in this
prospectus discuss some of the factors that could contribute to these
differences.

                                USE OF PROCEEDS
 
   
     Proxicom will receive estimated proceeds of approximately $48.7 million
from the sale of the 4,000,000 shares of common stock it is offering, net of
underwriting discounts and estimated expenses, and based on an assumed initial
public offering price of $13.50 per share. Proxicom will not realize any
proceeds from the sale of common stock by the selling stockholders.
    
 
     The primary purposes of this offering are to obtain additional capital,
create a public market for our common stock and facilitate future access to
public markets. Proxicom intends to use the majority of the offering's net
proceeds for working capital and general corporate purposes (including increases
in personnel and marketing activities). Proxicom will use a portion of the
proceeds to pay off a $1.4 million note payable to an investment bank for
services in connection with the IBIS Consulting transaction. The note accrues
interest at 7.0% per annum and matures upon the earlier of August 21, 1999 or
the completion of an initial public offering. Proxicom may use a portion of the
proceeds for strategic acquisitions. From time to time, in the ordinary course
of business, Proxicom evaluates potential acquisitions of businesses, products
or technologies. In March 1999, Proxicom reached an agreement to invest
approximately $360,000 in a joint venture company in Italy with Ericsson
Telecommunicazioni SpA. Other than this transaction, Proxicom has no present
understandings or agreements with respect to any acquisition of businesses,
products or technologies.
 
     Pending use of the net proceeds for the above purposes, Proxicom intends to
invest such funds in short-term, interest-bearing, investment-grade securities.
In addition to the use of the net proceeds received by it from the offering,
Proxicom also expects during the next 18 months to meet its working capital
requirements through existing cash and cash equivalents, short-term investments,
cash from sales of services, its credit facility and possibly other borrowings.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
                                DIVIDEND POLICY
 
     With the exception of distributions that three current Proxicom
subsidiaries made before Proxicom acquired them, Proxicom has never declared or
paid any cash dividends on its capital stock. Proxicom intends to retain future
earnings, if any, to finance the expansion of its business and does not expect
to pay any cash dividends in the foreseeable future. Also, Proxicom is
prohibited from paying cash dividends under the terms of its credit facility.

                                    DILUTION
 
     Proxicom's pro forma net tangible book value as of December 31, 1998, was
approximately $21.9 million, or $1.12 per share of common stock. We have
determined pro forma net tangible book value per share by subtracting intangible
assets from pro forma stockholders' equity and dividing that number by
19,617,833 pro forma shares of common stock outstanding as of December 31, 1998.
The preceding pro forma information gives effect to
 
   
     - the conversion of all shares of convertible preferred stock outstanding
       as of the date of this prospectus into 4,231,194 shares of common stock;
    
 
     - the $4.9 million charge associated with the issuance of Series D
       convertible preferred stock;
 
   
     - the exercise of warrants to purchase 1,011,378 shares of convertible
       preferred stock at $7.91 per share on April 13, 1999; and
    
 
     - the issuance of 829,771 shares of our common stock in our 1999 merger
       with ad hoc Interactive.
 
   
If Proxicom sells 4,000,000 shares of common stock in this offering at an
assumed initial public offering price of $13.50 per share and assuming our
receipt of the estimated net proceeds therefrom, our pro forma adjusted net
tangible book value as of December 31, 1998, would have been approximately $70.7
million, or $2.99 per share. This represents an immediate increase in such net
tangible book value of $1.87 per share to existing stockholders and an immediate
dilution of $10.51 per share to new investors. The following table illustrates
this per share dilution.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
     You should read the following discussion together with "Selected
Consolidated Financial Data," our consolidated and supplemental consolidated
financial statements and the notes to those financial statements elsewhere in
this prospectus. The discussion below would not be materially different if based
on the supplemental consolidated financial statements and related notes. In
addition to historical information, this discussion contains forward-looking
information that involves risks and uncertainties. Proxicom's actual results
could differ materially from those anticipated by such forward-looking
information due to competitive factors, risks associated with Proxicom's
expansion plans and other factors discussed under "Risk Factors" and elsewhere
in this prospectus.
 
OVERVIEW
 
     Our revenue is generally comprised of fees generated for professional
services. We provide our services primarily on a fixed-price, fixed-timeframe
basis. We use an internally developed process to estimate and propose fixed
prices for such projects. The estimation process accounts for standard billing
rates particular to each project, the technology environment and application
type to be applied, and the project's timetable and overall technical
complexity. A Proxicom senior management team member must approve all of our
fixed-price proposals. For these contracts, we recognize revenue using a
percentage-of-completion method primarily based on costs incurred. We make
provisions for estimated losses on uncompleted contracts on a contract-
by-contract basis and recognize such provisions in the period in which the
losses are determined. Less frequently, we provide services on a time and
materials basis. In such cases, we recognize revenue as we incur costs.
 
     Proxicom's financial results may fluctuate from quarter to quarter based on
such factors as the number, complexity, size, scope and lead time of projects in
which Proxicom is engaged. More specifically, these fluctuations can result from
the contractual terms and degree of completion of such projects, any delays
incurred in connection with projects, employee utilization rates, the adequacy
of provisions for losses, the accuracy of estimates of resources required to
complete ongoing projects and general economic conditions. In addition, revenue
from a large client may constitute a significant portion of Proxicom's total
revenue in a particular quarter.
 
     In August 1998, Proxicom completed a merger with IBIS Consulting, Inc. by
exchanging 4,988,297 shares of Proxicom common stock for all the common stock of
IBIS Consulting. In addition, IBIS Consulting options were converted into
options to purchase 345,034 shares of Proxicom common stock. Proxicom incurred
acquisition and merger costs of $2.8 million and stock-based and other
compensation expense of $18.2 million associated with IBIS Consulting. In
connection with this transaction, the president of IBIS Consulting was elected
to Proxicom's board of directors. In January 1998, Proxicom completed a merger
with Square Earth, Inc. by exchanging 534,999 shares of Proxicom common stock
for all the common stock of Square Earth. In addition, Square Earth options were
converted into options to purchase 41,474 shares of Proxicom common stock.
Proxicom incurred acquisition and merger costs of $130,000 in connection with
this transaction. Proxicom accounted for each of these transactions as a pooling
of interests. All prior period consolidated financial statements have been
restated to include IBIS Consulting's and Square Earth's results of operations,
financial position and cash flows.
 
RECENT DEVELOPMENTS
 
     As of March 26, 1999, Proxicom merged with ad hoc Interactive, Inc., a
California-based Internet solutions provider, by exchanging 829,771 shares of
Proxicom common stock and rights to receive 39,333 shares of Proxicom common
stock for all of the outstanding stock and stock rights of ad hoc Interactive.
The transaction was accounted for as a pooling of interests. In the
 
                                       17
<PAGE>   22
 
transaction, ad hoc Interactive stockholders became parties to the stockholders
agreement and registration rights agreement described in the "Certain
Transactions" section of this prospectus. Taking the merger into account,
Proxicom's revenue for the three-month period ended March 31, 1999 was $13.3
million, a 64.8% increase from revenue of $8.0 million for the three-month
period ended March 31, 1998. Proxicom recorded charges for merger related costs
that included legal and accounting fees and other costs of $300,000 and
$130,000, respectively, in the three-month periods ended March 31, 1999 and
1998. The $300,000 charge was directly associated with the ad hoc Interactive
merger. Giving effect to the charges and adjusted to reflect the ad hoc
Interactive merger, net loss for the three-month periods ended March 31, 1999
and 1998 was $148,000 and $487,000, respectively. Exclusive of the after-tax
effect of these acquisition related charges and adjusted to reflect the merger,
net income for the three-month period ended March 31, 1999 was $84,000, compared
to a loss of $408,000 for the three-month period ended March 31, 1998.
 
     In addition, in March 1999, Proxicom signed an agreement with Ericsson
Telecommuncazioni SpA. Under the agreement, Proxicom will make a 19.9%
investment in an Italian joint venture company. Ericsson will own the remaining
81.1% interest. The joint venture company will provide Internet solutions to
Italian-based businesses. The initial share capital of the joint venture company
will be approximately $1.7 million, which Proxicom and Ericsson will contribute
in proportion to their shareholder percentage interests. Proxicom will enter
into a services agreement with the joint venture company under which Proxicom
will provide consulting, project management and technical design services to the
joint venture's clients.

1998 COMPARED TO 1997
 
     Revenue.  In 1998, revenue increased $15.0 million, or 55.0%, to $42.4
million from $27.4 million in 1997. This increase in revenue reflects increases
in both the size and number of our client engagements. Approximately 65% of this
increase is attributable to increased engagement size and the remainder is
attributable to increased numbers of engagements. IBIS Consulting accounted for
$8.9 million, or 59%, of the increase in Proxicom's 1998 revenues.
 
                                       18
<PAGE>   23
 
Square Earth's contribution was not separately accounted for because its
operations were fully integrated into ours following the merger in January 1998.
 
     Cost of Revenue.  Cost of revenue consists primarily of salaries and
associated employee benefits for personnel directly assigned to client projects,
non-research and development efforts and non-reimbursed direct expenses incurred
to complete projects, such as technical consulting fees. These costs increased
$11.8 million, or 97.6%, to $23.9 million in 1998 from $12.1 million in 1997.
The increase during 1998 was due primarily to increases in the number of
personnel needed to service these engagements and the related complexity of the
engagements. Approximately 75% of the increase was attributable to personnel
cost increases. Service project personnel increased from 199 at December 31,
1997 to 311 at December 31, 1998. We usually do not fully utilize our consulting
and delivery personnel on billable projects during their initial months of
employment. During this time, they undergo training and become integrated into
our operations. Additionally, in 1998, we re-deployed engineers who were active
in developing and enhancing replicable frameworks. During this transition phase,
the engineer utilization was lower due to start-up requirements. Also, during
the second half of 1998, due to market conditions, customer demand in our
financial services and energy industry groups softened, which adversely affected
service utilization. As a percentage of revenue, cost of revenue increased to
56.3% during 1998 as compared to 44.1% during 1997.
 
     Gross Profit.  In 1998, gross profit increased $3.2 million, or 21%, to
$18.5 million from $15.3 million in 1997. The gross profit dollar increase
reflects the increase in revenue during 1998. As a percentage of revenue, gross
profit decreased to 43.7% during 1998 as compared to 55.9% during 1997. The
percentage decrease reflects reduced overall utilization of consulting and
delivery personnel as discussed in the cost of revenue section. Employee
utilization can be affected by multiple factors, including rapid growth and
reductions in the number or size of projects in any period. Reduction in
employee utilization rates could cause further decline in gross profit as a
percentage of revenue.
 
     General and Administrative.  General and administrative costs consist of
salaries for executive and selected senior management, finance, recruiting,
administrative groups and associated employee benefits, facilities costs
including depreciation and amortization, computer and office equipment operating
leases, training, travel and all other branch and corporate costs. These costs
increased $5.6 million, or 58.6%, to $15.3 million in 1998 from $9.7 million in
1997. This increase was due primarily to increases in personnel and facilities
and related costs due to expanded leasing commitments in Reston, VA, New York,
NY, San Francisco, CA and the establishment of new offices in Chicago, IL and
Munich, Germany to support the internal growth of our operations. Approximately
70% of the increase is attributable to the facilities and related cost
increases. As a percentage of revenue, general and administrative expenses
increased to 36.1% in 1998 as compared to 35.3% in 1997. We wrote off $959,000
in doubtful accounts in 1998, which included approximately $600,000 from
disputes with two customers. We believe the current allowance for doubtful
accounts balance of $500,000 is sufficient for other doubtful accounts.
 
     Selling and Marketing.  Selling and marketing costs consist primarily of
salaries and associated benefits, travel expenses of selling and marketing
personnel and promotional expenses. Selling and marketing costs increased $1.2
million, or 69.3%, to $2.9 million in 1998 from $1.7 million in 1997.
Approximately 60% of this increase was due to marketing program expenditures and
the remaining increase was due to increased personnel-related costs incurred in
sales promotion efforts. As a percentage of revenue, selling and marketing
increased to 6.8% from 6.3% during 1997.
 
     Research and Development.  Research and development costs, primarily
software development, consist of salaries assigned directly to research and
development projects, associated employee benefits and direct expenses incurred
to complete research projects, including non-
 
                                       19
<PAGE>   24
 
employee consulting. Research and development costs decreased $269,000, or
28.0%, to $692,000 in 1998 from $961,000 in 1997. We attribute this decrease to
our re-deploying engineers and technicians active in developing and enhancing
replicable frameworks to client service projects during the third quarter of
1998. For 1998 and 1997, we charged all of our costs for research and
development to operations as incurred. We did this because the period between
technological feasibility and general release was relatively short and the costs
incurred during this period were not significant.
 
     Acquisition and Merger Costs.  We incurred charges of approximately $2.9
million in 1998 for costs associated with the Square Earth and IBIS Consulting
transactions. These transaction costs related to professional fees and other
direct expenses. We did not record any such expenses for the year ended December
31, 1997 because we did not acquire any entities during that year.
 
     Stock-based and Other Compensation.  We incurred charges of $18.2 million
in 1998 for costs associated with our IBIS Consulting transaction. Of these
charges, $17.2 million related to the elimination of a repurchase requirement
for formula stock options and $1.0 million consisted of cash bonus payments
required under the historical IBIS Consulting plan. We did not record any
expense of this type for the year ended December 31, 1997 because no
formula-based stock options were exercised.
 
     Interest Income (Expense), Net.  Interest income (expense), net decreased
$191,000, or 238.8%, to interest expense of $111,000 in 1998 from interest
income of $80,000 in 1997. This decrease was due primarily to interest expense
we incurred from borrowings under our lines of credit during 1998 to support our
internal growth. Interest expense of $227,000 was offset by interest income of
$116,000 earned during 1998. We generally invest in U.S. Government treasury
bills and money market accounts. The amount of interest income fluctuates based
upon the amount of funds available for investment and prevailing interest rates.
 
     Income Tax Provision (Benefit).  Operating losses generated in 1998 were
carried back for tax purposes creating a tax benefit. The $900,000 income tax
benefit in 1998 represents a benefit from combined federal and state income
taxes at an effective rate of 4.2%, or 20.9% excluding the $17.2 million
non-deductible stock-based compensation charge. Income tax expenses of $330,000
in 1997 represented combined federal and state income taxes at an effective rate
of 10.9%. Our effective tax rate was favorably impacted in both 1997 and 1998 by
the transactions with Square Earth and IBIS Consulting, which were Subchapter S
corporations with pass-through tax status before the transactions.
 
1997 COMPARED TO 1996
 
     Revenue.  Revenue increased $15.0 million, or 120.0%, to $27.4 million in
1997 from $12.4 million in 1996. This increase is directly attributable to
increased client engagement size. IBIS Consulting and Square Earth accounted for
$6.3 million, or 42%, and $0.8 million, or 5%, respectively, of the increase in
Proxicom's 1997 revenue.
 
     Cost of Revenue.  Cost of revenue increased $7.3 million, or 153.9%, to
$12.1 million in 1997 from $4.8 million in 1996. This increase was due primarily
to increases in the size of our client engagements and the cost of additional
consulting and delivery personnel. Approximately 85% of the increase was
attributable to the increased personnel costs. We usually do not fully utilize
our consulting and delivery personnel on billable projects during their initial
months of employment. During this time, they undergo training and become
integrated into our operations. We had 126 consulting and delivery personnel at
December 31, 1996 and 199 at December 31, 1997. As a percentage of revenue, cost
of revenue increased to 44.1% during 1997 as compared to 38.3% during 1996.
 
     Gross Profit.  In 1997, gross profit increased $7.6 million, or 99%, to
$15.3 million from $7.7 million in 1996. The gross profit dollar increase
reflects the increase in revenue during
 
                                       20
<PAGE>   25
 
1997. As a percentage of revenue, gross profit decreased to 55.9% during 1997 as
compared to 61.7% during 1996. The percentage decrease reflects reduced
utilization of consulting and delivery personnel as discussed in the cost of
revenue section.
 
     General and Administrative.  General and administrative costs increased
$4.3 million, or 78.8%, to $9.7 million in 1997 from $5.4 million in 1996. This
increase was due primarily to increases in personnel, the leasing of a new
company headquarters in Reston, VA, costs incurred in connection with the
opening of our New York, NY office in 1997 and related facility costs to support
the growth of our operations. Approximately 65% of the cost increase is
attributable to increased facility and related costs.
 
     Selling and Marketing.  Selling and marketing costs increased $1.0 million,
or 162.4%, to $1.7 million in 1997 from $652,000 in 1996. This increase was due
to the expansion of our selling and marketing personnel to 15 employees at
December 31, 1997 from nine employees at December 31, 1996 and increased
promotional activities. Approximately 75% of the cost increase is attributable
to increased personnel costs.
 
     Research and Development.  Research and development costs increased
$557,000, or 137.9%, to $961,000 in 1997 from $404,000 in 1996. This increase is
attributable to increases in the number of engineers and technicians active in
developing and enhancing replicable frameworks. In 1997 and 1996, all of our
costs for research and development were charged to operations as incurred since
the period between technological feasibility and general release was relatively
short and the costs incurred during this period were not significant.
 
     Interest Income (Expense), Net.  Interest income increased $25,000, or
45.5%, to $80,000 in 1997 from $55,000 in 1996. This increase was due primarily
to our interest income earned on the invested portion of the proceeds of our
private financings during 1997. Interest income of $174,000 was offset by
interest expense of $94,000 from increased drawings under our lines of credit
during 1997 to support our internal growth.
 
     Income Tax Provision.  Income tax expense increased $145,000, or 78.4%, to
$330,000 in 1997 from $185,000 in 1996 and represented combined federal and
state income taxes at an effective marginal rate of 10.9% in 1997 and 14.6% in
1996. The comparatively low tax rate of 10.9% was caused primarily by the
transactions with Square Earth and IBIS Consulting, which were both Subchapter S
corporations with pass-through tax status before the transactions.

</TABLE>
 
     We have generally realized lower revenue in the first quarter of the year
than in the other quarters. We believe that this has been due primarily to
client budget cycles and the short-term nature of our contracts. We believe that
period to period comparisons of our operating results are not necessarily
meaningful and that you should not rely on these comparisons as indicators of
future performance.

LIQUIDITY AND CAPITAL RESOURCES
 
   
     In October 1998, Proxicom entered into a $10.0 million revolving credit
facility with NationsBank, N.A. to be used for working capital purposes and
permitted acquisitions. The interest rate on amounts borrowed under the credit
agreement is LIBOR plus 2.0%. The credit facility expires on August 31, 2000,
and will renew automatically for one additional year at the sole discretion of
NationsBank. The credit facility contains restrictions on Proxicom and its
subsidiaries (including a prohibition on the payment of cash dividends by
Proxicom) and requires Proxicom to comply with financial tests and to maintain
specified financial ratios. The credit agreement is secured by a first priority
lien on all current and future assets of Proxicom and its subsidiaries and a
first priority pledge of the stock of IBIS Consulting and Square Earth. As of
the date of this prospectus, Proxicom had no outstanding borrowings under the
credit facility.
    
 
     Cash and cash equivalents increased to $2.5 million at December 31, 1998,
from $2.3 million at December 31, 1997. Net cash provided by operating
activities of $1.3 million for 1997 was attributable to the growth in our
revenue and operations. The net cash used in operating activities of $4.0
million for 1998 was primarily offset with borrowings under our credit facility.
 
     Unbilled services increased $2.9 million from $1.4 million at December 31,
1997 to $4.3 million at December 31, 1998. This increase was primarily due to
growth in the size and complexity of our projects. Larger, more complex projects
typically require completion of specified performance milestones prior to
billing clients, as opposed to providing for monthly progress billing.
Approximately 25% of our projects in 1998 required performance milestones to be
reached before invoicing. We believe our project size and complexity may
continue to increase in the future and that an increasing portion of our
projects will require completion of milestones prior to billing. If this occurs,
our unbilled services receivables can be expected to increase. All unbilled
services receivables as of December 31, 1998 are expected to be invoiced during
1999.
 
     Capital expenditures of approximately $1.7 million, $2.0 million and $1.4
million for 1998, 1997 and 1996, respectively, were used primarily for computer
equipment, office equipment and leasehold improvements related to Proxicom's
growth. Capital expenditures for 1999 are expected to be approximately $2.0
million and will be made principally for computer equipment, internally used
software purchases and leasehold improvements to support our growth. A total of
approximately $631,000 was raised through the exercise of stock options in 1998,
and $3.5 million was raised through the private sale of convertible preferred
stock in 1997.
 
     In February 1999, Proxicom completed the sale of 1,218,333 shares of Series
D convertible preferred stock for $7.3 million. At the closing of this offering,
all of these shares will be converted into common stock on a one-for-one basis.
Proxicom will be required to take a $4.9 million charge to additional paid-in
capital for the difference between the conversion feature and the estimated fair
value of the underlying common stock. Although not reflected on the statement of
operations, the charge will be reflected as a reduction to income and earnings
per share available for common stockholders. See "Certain Transactions -- Stock
Purchase Agreements and Related Matters -- Series D Purchase Agreement."
 
   
     In connection with the issuance of Series A convertible preferred stock,
Proxicom issued warrants to purchase 1,011,378 shares of Series A convertible
preferred stock. The warrants were exercised for a purchase price of $8.0
million on April 13, 1999.
    
 
     Proxicom anticipates that the net proceeds of this offering, together with
existing sources of liquidity and funds generated from operations, should
provide adequate cash to fund its currently anticipated cash needs through at
least the next 18 months. To the extent Proxicom is unable to fund its
operations from cash flows, it may need to obtain financing from external
sources in the form of either additional equity or indebtedness. There can be no
assurance that additional
 
                                       23
<PAGE>   28
 
financing will be available at all, or that, if available, such financing will
be obtainable on terms favorable to Proxicom.
 
YEAR 2000 READINESS DISCLOSURE
 
     Background.  Many computer systems and applications currently use two-digit
fields to designate a year. As the century date change occurs, date-sensitive
systems will recognize the year 2000 as 1900, or not at all. This inability to
recognize, or properly treat, the year 2000 may cause systems to process
financial and operational information incorrectly, resulting in system failures
and other business problems.
 
     Risk Factors.  We may experience operations interruptions because of year
2000 problems. Clients' and potential clients' purchasing patterns may be
affected by year 2000 issues as companies expend significant resources to
correct their current systems for year 2000 compliance. These clients and
potential clients may have fewer funds available to purchase our services. Also,
we may experience operations difficulties caused by undetected errors or defects
in the technology we use in our internal systems. We may become involved in
disputes regarding year 2000 problems involving solutions we developed or
implemented or the interaction of our Internet solutions with other
applications. Year 2000 problems could require us to incur delays and
unanticipated expenses. We have formulated an approach to address our exposure
to these risk factors.
 
     Approach.  We are assessing the impact of the year 2000 issue on our
current and future products, internal information systems and non-information
technology systems. We have performed a preliminary assessment of the year 2000
readiness of our information technology systems, including the hardware and
software we use to provide and deliver our Internet solutions. We plan to
perform a year 2000 simulation on our software and systems during the second
quarter of 1999. Based on the results, we will revise our solutions software
code as necessary.
 
     We will require all vendors who provide material hardware or software for
our information technology systems to provide assurances of their year 2000
compliance. We will also seek assurances of year 2000 compliance from our
material non-information technology providers. We plan to complete this process
during the first half of 1999. Until our testing is complete and all of our
material vendors and providers are contacted, we will not be able completely to
evaluate whether our systems will need to be revised or replaced.
 
     We have identified processes that will require year 2000 readiness testing.
We are in the process of establishing dedicated test environments for year 2000
readiness testing. We anticipate that testing will be largely complete by the
second quarter of 1999.
 
     Status.  Our testing to date has included our major infrastructure items,
hardware platforms and operating systems in our largest offices. Desktop
computing, servers, switching and routing platforms have been inventoried in
most locations, with only minor modifications required to the network and
routing platforms. Personal computer platforms have been identified and tested
in our Reston, VA and New York, NY locations. This effort is estimated to be 80%
complete. Installation of the software components that will bring the computing
platforms into compliance is estimated to be 25% complete, with full completion
scheduled in all locations by the end of April 1999. Embedded systems are
considered to be tested at a 20% level, with full testing to be completed by
June 1999.
 
     We have largely completed the implementation of year 2000 compliant
internal computer applications for our main financial and order processing
systems.
 
     Cost.  Based on the work done to date, we predict that the cost for work
and material and upgrades needed to complete our year 2000 certification process
will be approximately $150,000. This includes the cost of material upgrades,
software modification and related consulting fees.
 
     Contingency Plans.  As discussed above, we are engaged in an ongoing year
2000 assessment and have not yet developed any contingency plans. We will assess
the results of our year 2000 simulation testing and third-party vendor and
service provider responses to determine the nature and extent of any contingency
plans.

INDUSTRY BACKGROUND
 
     The Internet presents opportunities to transform businesses and entire
industries as organizations exploit its potential to extend and enhance their
business activities. Companies are using the Internet to communicate and
transact business on a one-to-one basis with existing customers and to target
and acquire new customers. At the same time, companies are using the Internet to
collaborate with their supply-chain partners, enable electronic commerce and
manage distribution relationships. The Internet has also allowed businesses to
identify new product and service offerings which extend and complement their
core markets. As a result, organizations are investing in the strategic use of
Internet solutions to transform their core business and technology strategies.
 
     Faced with growing competition, deregulation and globalization, companies
are increasingly looking to utilize Internet technology to help build
competitive advantage. Much as client/server technologies opened information
access within organizations beginning in the late 1980s, the Internet now offers
the potential for organizations to extend their businesses beyond traditional
limits. The Internet extends the business role of technology from
employee-focused productivity enhancement to customer-focused revenue
generation, raising the importance and complexity of new technology deployment.
 
     Successful adoption of the Internet in this new context poses strategic,
technical and creative design challenges. Alignment of business and Internet
strategies requires an understanding of how the Internet transforms
relationships between businesses and their internal organizations, customers and
business partners. Also, companies facing technology investment decisions often
need outside technical expertise to recognize \viable Internet tools, develop
feasible architectures and implement strategies. Companies must also be able to
integrate new Internet applications with their existing systems. Finally, a
successful solution requires that the Internet application, particularly the
user interface, be engaging and easy to use.
 
     Few businesses have the range of skills necessary to successfully transform
the way they use technology and implement Internet solutions. Moreover, it is
difficult to find these skills externally in the supply-constrained Internet
professional services market. Even if businesses obtain skills in all three of
the strategy, technology and creative disciplines, they often have little
experience coordinating them to exploit fully the Internet and other advanced
technologies.
 
                                       25
<PAGE>   30
 
     The combination of these factors is creating a significant and growing
demand for third-party Internet professional services. International Data Corp.,
a technology industry research firm, forecasts that the market for Internet and
electronic commerce services worldwide will grow from $4.6 billion in 1997 to
$43.7 billion by 2002. Forrester Research, Inc., another technology industry
research firm, estimates the market for Internet and electronic commerce
services will grow from $5.4 billion in 1998 to $32.7 billion by 2002. These
projections represent a compound annual growth rate of more than 55% over these
periods. Forrester Research predicts that the Internet will be one of the
fastest-growing areas within the information technology services industry. While
business to consumer solutions are expected to continue to be a large part of
the Internet and electronic commerce services market, Proxicom believes that
business to business corporate intranet/extranet solutions will represent a
growing percentage of the overall market.
 
     Vendors addressing the Internet professional services market can be broadly
divided into four major categories:
 
     - Large systems integrators provide technology expertise across a wide
       range of offerings which address business process requirements.
 
     - Specialty systems integrators frequently offer traditional distributed
       computing models adapted to the Internet.
 
     - Strategy consulting firms seek to help companies define models of how
       they can use the Internet as a new channel and knowledge-sharing tool.
 
     - Internet professional services providers bring Internet expertise, often
       with a focus on either the creative, technology or strategy element.
 
While vendors in each category have specific strengths, each tends to address
only a piece of the Internet puzzle. Few vendors addressing the Internet
professional services market successfully integrate business and marketing
strategy with expertise in Internet-specific technology and creative design
services to help businesses achieve the full potential that the Internet offers.
 
     Proxicom believes organizations are increasingly searching for a
single-source professional services firm that can deliver integrated strategy,
technology and creative design skills specifically for the Internet.
Furthermore, Proxicom believes that organizations will increasingly look to
Internet solutions providers that can leverage industry best practices, increase
predictability of success for Internet solutions and decrease risks associated
with implementation.

releases to incorporate user feedback and to keep pace with the Internet's
ongoing technological changes. The four phases of the Proxicom Process'
development cycle are (a) Define Internet Strategy, (b) Plan Solution, (c)
Design Solution and (d) Implement Solution. Using the Proxicom Process, Proxicom
structures projects
                                       26

tightly and offers fixed-price, fixed-timeframe engagements. This provides
clients with greater certainty regarding the time and cost of implementation.
Proxicom's approach improves quality of delivery and alignment of an Internet
initiative with a client's business. This approach is geared toward minimizing
the risk of technical or competitive obsolescence faced by companies using the
Internet.
 
     Integrated Internet Strategy, Technology and Creative Design
Services.  Proxicom delivers its solutions through collaborative,
multi-disciplinary teams that apply the collective strengths of their strategy,
technology and creative design professionals. Proxicom believes that this
approach results in coordinated planning among its professionals from all three
disciplines, a challenge that many organizations struggle to address. Proxicom's
delivery process fosters collaboration within its multi-disciplinary teams to
help clients achieve internal cooperation among previously independent business
functions. Proxicom believes its multi-disciplinary approach results in better,
more efficient Internet solutions in which business and communications
strategies are consistently balanced with the opportunities and capabilities of
Internet technologies.
 
     Industry and Business Domain Expertise.  Over the course of more than 600
engagements since 1994, Proxicom has gained significant expertise in specific
industries and types of business solutions. Proxicom's expertise provides
clients with a clear vision of the Internet's potential to improve their
business processes and competitive positions. Proxicom organizes its delivery of
services into vertical industry groups: energy and telecommunications, financial
services, retail and manufacturing and service industries. Through strategic
hires and numerous engagements, Proxicom has developed significant knowledge and
expertise in its targeted industries. Proxicom complements its industry
specialization with expertise in cross-industry solution areas such as
electronic commerce, supply chain management and interactive marketing. Proxicom
leverages its experience in these industries and solution areas across the
entire company through best practices as well as proprietary solution
frameworks, software tools and components to provide clients the full value of
Proxicom's industry and business domain expertise.
 
     In-depth Internet and Advanced Technology Expertise.  Proxicom has
developed an in-depth understanding of the specific challenges of deploying
Internet solutions. Proxicom is expert at building, extending and complementing
technologies that have the ability to transform businesses. Proxicom helps its
clients utilize leading-edge technologies and minimize the expenses associated
with hiring, training and retaining scarce information technology skill sets.
Because Proxicom's expertise is not limited to a single technology or
architecture, Proxicom is able to help clients choose the appropriate technology
to provide the best long-term business solution.
 
     Knowledge Management and Knowledge Sharing Infrastructure.  Through the
Proxicom Process, Proxicom continuously incorporates the multi-disciplinary
knowledge gained in Proxicom's engagements. This intellectual capital is tracked
and stored in Proxicom's corporate intranet, which acts as an integrated
knowledge management repository. Proxicom's intranet is both a solutions library
that facilitates the dissemination of intellectual capital across Proxicom and
an internal project management system that captures detailed information on the
resources required to achieve specific tasks on a project. In this way,
Proxicom's clients can benefit from industry best practices as well as
Proxicom's experiences. This system improves Proxicom's ability to predict
project completion requirements and increases the reusability of its
intellectual capital, thereby reducing risk for its clients. Proxicom's
week-long "boot camp" orientation and training program for all new employees
also facilitates knowledge sharing.
 
PROXICOM'S GROWTH STRATEGY
 
     Proxicom's strategy is to build upon its position as a leading provider of
transformational Internet solutions that add significant and measurable business
value to Global 1000 companies and other large organizations. The following are
the key elements of Proxicom's strategy.
 
                                       27
<PAGE>   32
 
     Leverage Existing Clients.  Proxicom believes it must continue to satisfy
its customers. A strong track record of delivering high quality Internet
solutions often increases the amount, scope and sophistication of services
requested by existing clients. This reinforces Proxicom's growing reputation as
an innovative provider of mission-critical Internet solutions. Proxicom also
believes that maintaining a reputation for delivering innovative Internet
solutions and client satisfaction will increase its ability to attract new
clients through increased referral-driven sales and strong references.
 
     Further Penetrate our Vertical Markets.  Proxicom believes that its
expertise in specific industry dynamics and solutions considerably enhances its
ability to help companies apply the Internet to gain competitive advantage. In
each of its vertical industry groups, Proxicom employs industry experts, pursues
targeted sales and marketing, develops industry-specific offerings and
capitalizes on referrals from existing clients. Proxicom will continue to
emphasize this focus and seek to expand the scope of its industry expertise.
 
     Continue Geographic Expansion.  Proxicom believes that expanding
geographically will increase its ability to attract and better service clients.
Proxicom has already established offices in Reston, VA, San Francisco, CA, New
York, NY, Munich, Germany, Sacramento, CA, Chicago, IL and Houston, TX. All of
these offices have contributed to Proxicom's continued ability to attract large
clients. Proxicom plans to continue establishing offices in key geographic
locations through an integrated process of organic growth and targeted
acquisitions. Recently, Proxicom reached a preliminary understanding with
Ericsson Telecommunicazioni SpA to invest in a joint venture company. Through
the joint venture company, Proxicom would deliver its Internet consulting
services in Italy.
 
     Hire and Retain Skilled Professionals.  Proxicom believes its delivery of
integrated strategy, technology and creative design services distinguishes it
from other Internet professional services providers. To deliver these services,
Proxicom must hire and retain skilled professionals in all three disciplines and
continue to foster collaboration among them. Proxicom has a dedicated
organizational development team that initiates and oversees the training and
development of Proxicom's professionals. Key organizational development
initiatives include a week-long "boot camp" orientation and training program for
all new employees and "Proxicom University," which provides ongoing technical
and project management classes as well as career path management and guidance.
Proxicom is committed to recruiting and hiring quality professionals and to
maintaining a culture that motivates its staff while cultivating collaboration
and retention.
 
     Evolve the Proxicom Process.  Proxicom believes that continued evolution of
the Proxicom Process will strengthen its competitive position. Proxicom enhances
the Proxicom Process by incorporating best practices identified over numerous
engagements. This enables clients to benefit from Proxicom's cumulative
experience. Proxicom will continue to refine and enhance the Proxicom Process to
enable continued delivery of high quality solutions to clients on time and on
budget.
 
     Leverage Technology Partnerships.  Proxicom believes its relationships with
leading technology vendors, such as Microsoft Corporation and Netscape
Communications Corporation, will provide increased visibility and sales
opportunities. Proxicom's status as a Microsoft Certified Solution Provider
Partner has yielded considerable sales opportunities. Proxicom has also formed
strategic alliances with leading hosting and co-location providers, such as
Exodus Communications, Inc. Proxicom is committed to furthering these
relationships and building other strategic partnerships that can contribute to
its growth.
 
     Extend Reusable Solutions.  Proxicom leverages those elements of its
Internet solutions for which there is repeat customer demand. Reusable solutions
increase productivity, accelerate solutions development and enhance the
profitability of Proxicom's engagements. Proxicom's industry and business
solutions experts develop replicable solutions for target markets, including
best practices, tools, functionality, software and standard interfaces for
leading third-party
                                       28
<PAGE>   33
 
applications. Proxicom has a dedicated framework reuse group that supports these
efforts and leverages them across the organization. The group also identifies
software reuse opportunities before and after client engagements, prepares code
for reuse and maintains version control. Proxicom intends to continue to
leverage its experience to create reusable solutions that can be used in future
engagements. On most engagements, Proxicom retains the right to reuse the
solutions' underlying components.

THE PROXICOM PROCESS
                                  [ARTWORK]
 
     Proxicom delivers its services using a proprietary multi-phase methodology
called the Proxicom Process, which serves as a roadmap to define, develop and
manage Internet solutions. The Proxicom Process benefits Proxicom's clients by
enabling Proxicom to offer fixed-price, fixed-timeframe engagements and thereby
meet clients' needs for certainty. The iterative nature of the Proxicom Process
enables Proxicom to refine applications through the extensive use of prototypes
and phased application releases. Proxicom also uses the Proxicom Process to
reduce the time-to-market of a deployed solution. The Proxicom Process fully
integrates working groups and emphasizes collaboration between the Proxicom team
and the client.
 
     Proxicom uses the Proxicom Process to manage project scope and client
expectations and to deliver solutions on time and on budget. The Proxicom
Process offers mechanisms for rapid adoption of best practices and reinforces
consistent quality across all projects. It provides for quality assurance with
unit, integration and systems testing procedures throughout design, development
and deployment to ensure quality delivery and client satisfaction. The Proxicom
Process also aggregates and replenishes the intellectual capital of Proxicom's
entire organization, thereby leveraging Proxicom's cumulative experience.
Proxicom continually seeks to evolve the Proxicom Process by identifying best
practices during project reviews with Proxicom's delivery teams and clients.
 
     All of Proxicom's client engagements utilize the Proxicom Process, which
Proxicom customizes to suit specific project needs. The inclusion, timing and
cost of any phase will depend on the type of solution and the scope of work. The
Proxicom Process is scalable and may be used effectively for projects of all
sizes. The following are the phases of the Proxicom Process:
 
     Define Internet Strategy.  The scope of the Define Internet Strategy phase
ranges from defining an Internet vision for the client's overall business to
developing a strategy for a specific Internet solution or offering. The Internet
vision is a business strategy engagement where Proxicom assesses the client's
opportunities to leverage the Internet both as a technology and as a profitable
business medium. The Internet vision engagement often involves Proxicom's
interactive marketing discipline, which assesses market opportunities and
competition. For a specific Internet solution, the Define Internet Strategy
deliverable examines the strategic
 
                                       30
<PAGE>   35
 
objectives of the solution, how its success will be measured, and how the
solution will be marketed, launched and publicized.
 
     Plan Solution.  The Plan Solution phase determines the scope and nature of
the engagement and articulates the project's tactical objectives. These
objectives are refined over the course of multiple working sessions with the
client. This phase results in a project plan outlining tasks, deliverables and
key milestones, which are translated into a detailed contractual agreement for
the next phases of the engagement. The plan includes detailed cost estimates as
well as organizational roles and responsibilities for Proxicom, the client and
other parties.
 
     Design Solution.  The Design Solution phase uses rapid prototyping
techniques in an iterative fashion to determine and refine application
requirements and specifications. A multi-disciplinary team works in tandem with
the client to translate the business, marketing, technical and creative
requirements of the solution into a cohesive design. This phase generally has
four major parts.
 
     -  Business Requirements Definition.  Requirements, which form the
        foundation for successful solution designs, are refined through
        successive iterations and collaborations with appropriate client and
        user constituencies.
 
     -  Creative Design Composition.  Content and information for the solution
        are defined and organized. The look and feel of the solution is designed
        in a series of detailed site flow compositions that show page content,
        navigation and links. Proxicom works closely with the client to
        coordinate the brand image and advertising campaigns on an ongoing
        basis.
 
     -  Technical Architecture Definition.  The solution is analyzed from a
        technical viewpoint, including the development, test and operational
        architectures required. The technical, application and data
        architectures of the solution are documented, addressing the
        requirements for hardware, software and network environments, databases
        and third party products.
 
     -  Specification and Prototype Development.  Rapid prototyping is used to
        construct portions of the solution. A visual prototype is used to define
        page style, layout, information architecture and navigation. Functional
        prototypes are used to test complex processing requirements and the
        effectiveness of the application and data architectures. This iterative
        process allows the client to review and refine the application as it
        takes shape during the development process.
 
     Implement Solution.  The Implement Solution phase involves the further
enhancement of prototypes to construct a production-ready solution by further
developing and combining the prototypes. Unit, integration and systems testing
and quality assurance procedures are incorporated throughout the development
process to verify that the solution conforms with the design specifications.
Testing is performed across multiple browsers and environments to ensure uniform
accessibility. Once the client gives final approval of the developed solution,
Proxicom works with the client through installation and roll-out. This work may
include system migration, data conversion and training.
 
SALES AND MARKETING
 
     Proxicom's sales and marketing activities are aligned with its vertical
industry groups. Each vertical industry group vice president is responsible for
developing Proxicom's business within each respective industry, targeting new
clients and cultivating repeat business with existing clients. Proxicom believes
that its vertical approach is a differentiating factor during the sales process,
as it demonstrates Proxicom's understanding of the client's specific business
and technology issues. Proxicom's sales approach is highly consultative and
involves industry and solutions experts who draw on their practical experiences
with other clients that have faced similar challenges. Proxicom also assigns
senior client executives to strategic accounts to support and expand client
relationships.
                                       31
<PAGE>   36
 
     Proxicom has 13 dedicated direct sales professionals to support the
vertical industry groups. These professionals are assigned to specific
geographic regions in order to maximize responsiveness to clients. They work
jointly with the vertical industry groups to secure new opportunities and manage
the sales process. Service directors responsible for delivery collaborate with
the sales professionals to form a joint sales approach for identifying and
winning follow-on business. Proxicom's marketing efforts are designed to create
brand recognition and demand for the Proxicom's services. Proxicom's four-person
marketing team is organized to provide support for each vertical industry group.
Marketing programs include promoting customer success stories, creating industry
and solution specific campaigns, pursuing public relations opportunities and
promoting Proxicom's executives for speaking opportunities and
Proxicom-sponsored event management.
 
     Proxicom complements its internal sales and marketing efforts with selected
industry partnerships. Several Internet product vendors such as Microsoft
Corporation, Netscape Communications Corporation, Oracle Corporation,
BroadVision, Inc. and TRADE'ex Electronic Commerce Systems, Inc., and high-end
hosting vendors, such as Exodus Communications, Inc., MCI WorldCom, Inc. and ANS
Communications, Inc., recommend Proxicom services to their clients. See
"-- Marketing and Technology Relationships."

CASE STUDIES
 
CALPHALON CORPORATION: BUSINESS-TO-CONSUMER INTERNET COMMERCE
 
     Calphalon Corporation is a leading U.S. manufacturer of cookware products
and kitchen accessories. The company's first Internet initiative was an
internally developed, one-way, static Web site. In preparation for the holidays,
Calphalon sought to launch a new site to take advantage of the full interaction
potential of the Internet. Calphalon engaged Proxicom to design and deploy its
new consumer focused transactional offering.
 
     The consumer product experts in Proxicom's retail and manufacturing
practice began by determining an Internet strategy that would best differentiate
Calphalon. Through a rapid, iterative development process, Proxicom completed
the project's first phase in less than a month: a transaction enabled solution
including a select catalog of product information and images. Subsequent
expansion increased information for consumers, adding the full complement of
product information, new indexed product instruction, a database of recipes and
expanded transactions and interactive capabilities. A key success of the
solution was Proxicom's design of the site, which was integrated with
Calphalon's overall communications programs and image. The design, based on an
easy-to-navigate information architecture, was created to ensure an intuitive
user experience that meant quick adoption and satisfaction for its audience.
 
     Proxicom helped Calphalon introduce a new means of doing business through
an Internet channel. The solution differentiates Calphalon's offering in
cookware products by uniting a complement of communications, content and
transaction capabilities through a single source. Using the site, Calphalon
gains invaluable knowledge of its customers and their interests. It establishes
a direct connection with a new audience and capitalizes on a new opportunity to
influence and serve the market for cooking enthusiasts. At the same time,
Calphalon enhances its brand presence. The solution has created efficiencies for
Calphalon's business and has been used to introduce a new line of cutlery
products to test market acceptance. As a result of the Internet initiative,
Calphalon has engaged Proxicom for ongoing site enhancements.
 
AMERICAN ELECTRONICS ASSOCIATION: A NEW INTERNET-BASED MEMBERSHIP SERVICE
 
     The American Electronics Association is the largest high-tech trade
association, with over 3,000 member companies nationwide such as Intel
Corporation, Sun Microsystems Inc., Amazon.com, Yahoo! Inc. and Cisco Systems,
Inc. As a trusted partner for information, industry benchmarking, public policy,
international issues and conferences, AEA sought to leverage the Internet to
transform how it attracted and worked with members. Following a rigorous
competitive process, AEA selected Proxicom because of its experience and
integrated mix of strategy, technology and creative design skills. Proxicom's
charter was to reposition AEA and electronically enable their entire business
through a new Internet-based membership service.
 
     In close collaboration with AEA, Proxicom's team repositioned the AEA brand
and communications identity. The new identity will serve as the front-end to a
fully functional Internet and extranet integrated into AEA's core systems.
Public and private sections are built on the Microsoft Site Server 3.0 Commerce
Edition platform which interacts with the legacy systems and builds off of
membership directory data. The site allows for distributed and dynamic rendering
of content that is presented to users through sophisticated personalization
based on their profile. The electronic commerce solution permits purchasing with
real-time variable pricing for AEA events and products. Additional features
include online discussions in support of grassroots campaigns, member generated
content, a comprehensive job bank section, queries across research data and a
powerful site analysis tool for audience and return on investment analysis.
 
     The solution will redefine how AEA markets itself through a new brand and
message to the industry. AEA will gain a new, easier means to create and
distribute information and a powerful
 
                                       33
<PAGE>   38
 
way to personalize it for the end user. This solution will be a vehicle that
increases sales and allows for direct, real-time communications with members and
industry experts. It will also provide a sophisticated knowledge management,
communications and commerce portal that will enable AEA to better attract and
retain members.
 
GE PLASTICS: INTRANET KNOWLEDGE MANAGEMENT SYSTEM
 
     GE Plastics, a business unit of the General Electric Company, faced a
problem common to many businesses: electronic methods for internal communication
and information-sharing were inefficient. Employees attempting to share
marketing, technical, sales and customer service information were consistently
faced with time-consuming searches among decentralized databases and file
systems as well as un-networked personal computers. GE Plastics engaged Proxicom
to help define and deploy an organization-wide intranet that would facilitate
knowledge sharing across its five divisions.
 
     Working closely with GE, Proxicom's dedicated client service team began the
project by benchmarking GE Plastics' internal business processes and
technologies. A strategy was then developed to build an intranet that was
searchable across the multiple business units and would leverage their immense
storehouses of information. Proxicom rapidly designed and deployed an
easy-to-use intranet that tied into the legacy databases. Through the intranet,
product, marketing, customer and technology data has become accessible and
searchable from a browser-based interface that simulates a centralized data
source. The intranet has facilitated many workflow improvements, including the
automation of the GE Plastics' customer satisfaction review process, which
includes extensive customer satisfaction surveys. Prior to the intranet, the
process was entirely paper-based. Currently, the surveys are not only available
on the intranet but are part of an overall workflow process incorporating trend
analysis and audit trail capabilities.
 
     The intranet established at GE Plastics leveraged its legacy system
investments and enabled more rapid deployment of solutions at significantly
lower cost than a major infrastructure overhaul. GE Plastics' global intranet
knowledge management system produces significant benefits for GE Plastics as a
valuable decision-making tool. Effectiveness of marketing, sales, information
technology and customer service personnel has improved dramatically, as
employees throughout GE Plastics are spending less time searching and entering
information and more time doing their jobs, making decisions and implementing
strategic plans.
 
PACIFIC GAS AND ELECTRIC COMPANY: ENTERPRISE DISTRIBUTED OBJECT APPLICATION
 
     Pacific Gas and Electric Company, one of the largest investor-owned
utilities in the country, provides gas and electric services to 12 million
people throughout Northern California. With the Gas Accord, approved by the
California Public Utilities Commission in August 1997, Pacific Gas and Electric
was faced with fundamental changes in its gas business and an increasingly
competitive environment. Pacific Gas and Electric had an opportunity to increase
revenue by offering value-added services, such as different levels of service,
flexible billing options, and helping customers reduce their operational and
financial risk. Pacific Gas and Electric chose Proxicom as its development
partner to design, develop and implement its comprehensive gas transportation
system.
 
     The oil and gas experts in Proxicom's energy practice began by helping
Pacific Gas and Electric design a system that would be flexible enough to
facilitate all business transactions. This meant the system had to do more than
move the gas from place to place; it had to include functionality for selling
Pacific Gas and Electric 's transmission and storage capacity, trading the
commodity gas among energy marketers, delivering the gas to intermediaries and
end users, and billing customers (gas producers, gas marketers and end users).
The real challenge for Proxicom and Pacific Gas and Electric was that the system
had to be developed before the new structure was finalized, which meant that
requirements were changing throughout the development process. Proxicom built a
system that allowed instant access to pipeline capacity and throughput
                                       34
<PAGE>   39
 
data, was dispersed across 20 states and Canada, and was extensible enough to
allow for quick time to market new services. Whereas the old system had taken
Pacific Gas and Electric six years to build, this system was put into operation
just 12 months after the requirements were developed. Proxicom used an iterative
object-oriented development methodology to create a multi-tiered application
architecture so that changes in business rules, as are often necessitated by a
rapidly changing industry, could be easily incorporated.
 
     Proxicom helped Pacific Gas and Electric become a competitive player at the
forefront of the newly restructured gas industry. The system that was developed
is at the core of Pacific Gas and Electric 's gas business, accounting for $360
million in revenue, with two million residential, 1,200 industrial and 150
energy marketer customers. This new system provides strategic trend information
to Pacific Gas and Electric and enables it to offer a high level of services to
its customers, including remote access via the Internet. Because the gas
transportation system was designed to be flexible and extensible, Pacific Gas
and Electric and Proxicom were able to reuse the components developed under the
Gas Accord to develop a gas gathering contract system in just three months. This
new system allows Pacific Gas and Electric to leverage its existing system
infrastructure and reduce maintenance and support costs.
 
MARKETING AND TECHNOLOGY RELATIONSHIPS
 
     Proxicom complements its internal sales and marketing efforts with formal
and selected industry partnerships. A number of Internet product vendors,
including Microsoft Corporation, Netscape Communications Corporation, Oracle
Corporation, BroadVision, Inc. and TRADE'ex Electronic Commerce Systems, Inc.,
and leading hosting providers, including Exodus Communications, Inc., Digex
Incorporated, MCI WorldCom, Inc. and ANS Communications, Inc., recommend
Proxicom services to their clients.
 
     Proxicom has arrangements with a number of technology vendors to obtain
privileged access to their technologies. By establishing these alliances,
Proxicom has gained pre-release technology which enables it to maintain
leading-edge technical skills. Microsoft, Netscape and BroadVision have all
provided advance versions of their technologies to Proxicom. Obtaining the
validation by industry leaders such as Microsoft and Netscape has added
considerably to Proxicom's visibility, credibility and brand image. Proxicom's
relationships with Microsoft and BroadVision are summarized below.
 
     Proxicom has been a Microsoft Certified Solution Provider Partner since
1995, when it began actively cultivating a broad base of Microsoft products,
skills and certifications. In the spring of 1998, Proxicom was promoted to
Solutions Provider Partner, the highest level within that program. The Solution
Provider Partner program provides Internet-specific technical assistance.
Through this program, Microsoft and Proxicom conduct joint marketing efforts,
training programs and sales initiatives, in particular targeting Proxicom's
specialty industries.
 
     Recently, Proxicom has become a BroadVision Integration Partner.
BroadVision and Proxicom work together to deploy BroadVision's "One-to-One"
commerce platform. In addition, several joint marketing events and sales
activities are planned. As an Integration Partner, Proxicom receives high-level
technical and sales support from BroadVision. Creating this relationship with
BroadVision allows Proxicom to enter the packaged applications systems
integration market, leveraging its Internet expertise with the market demand for
rapid deployment of new technology.
 
     In addition, in March 1999, Proxicom signed an agreement with Ericsson
Telecommunicazioni SpA. Under the agreement, Proxicom made a 19.9% investment in
an Italian joint venture company. Ericsson will own the remaining 81.1%
interest. Proxicom will provide Internet solutions to Italian-based businesses
through the joint venture company.

IBIS CONSULTING MERGER
 
     On August 21, 1998, Proxicom merged with IBIS Consulting, Inc. by
exchanging 4,988,297 shares of Proxicom common stock and options to purchase
345,034 shares of Proxicom common stock for all the common stock of IBIS
Consulting. IBIS Consulting is a San Francisco-based Internet professional
services provider. IBIS Consulting's services and culture are highly
complementary to those of Proxicom. Proxicom has integrated IBIS Consulting's
systems, Internet professionals and management into its operations. As a result
of this transaction, Proxicom has expanded its presence to the West Coast and
broadened its resource base, sales reach and expertise.
 
PERSONNEL AND CULTURE
 
     As of December 31, 1998, Proxicom had 380 employees. Of these, 311 were
consulting and service delivery professionals, and 69 were management and
administrative personnel performing marketing, sales, human resources, finance,
accounting, legal, internal information systems and administrative functions.
 
     Proxicom believes that its ability to provide integrated business strategy,
technology and creative design services is dependent upon the continuation of
its culture of mutual respect among the three disciplines. As a result,
Proxicom's employees and its culture are fundamental to the value proposition it
offers clients. Proxicom's culture is predicated on personal integrity, open
communications, collaboration and professional development. Proxicom fosters an
entrepreneurial spirit that attracts talented professionals, creates innovative
solutions and provides the opportunity for every individual to succeed.
 
     Proxicom has a particular emphasis on recruiting and retaining people with
leading-edge technical skills and project management experience. Proxicom has
been very successful with internal referral-driven recruiting, which has
accounted for nearly one-third of its hires to date. Proxicom continues to
encourage employee referrals with monetary incentives. Proxicom has developed a
structured recruiting program including a staff of dedicated recruiters tasked
with bringing in experienced professionals, MBA and college hires, and
maintaining a tracking database of potential candidates. Proxicom runs a
year-round internship program with several leading undergraduate and MBA
programs.
 
     In addition to recruiting, Proxicom is committed to employee training and
retention. Proxicom has a dedicated organizational development team that
initiates and oversees the training and development of Proxicom's professionals.
Key organizational development initiatives include a week-long "boot camp"
orientation and training program for all new employees and "Proxicom
University," which provides ongoing technical and project management classes as
well as career path management and guidance. To support its internal initiatives
for employee development, Proxicom has also instituted programs such as tuition
reimbursement and external training. Proxicom plans to continue to invest in
attracting the best employees and in maintaining a low turnover rate.
 
     None of Proxicom's employees is represented by a labor union, nor has
Proxicom ever experienced a work stoppage. Proxicom believes its employee
relations are good.
 
COMPETITION
 
     The market for Proxicom's services is subject to rapid technological change
and increased competition from large existing players, new entrants and internal
information systems groups. Traditional players competing in this space can be
broken down into four major categories -- large systems integrators (e.g.,
International Business Machines Corporation, Andersen Consulting and Computer
Sciences Corporation), specialty systems integrators (e.g., Cambridge Technology
Partners, Inc. and Sapient Corporation), strategy consulting firms (e.g.,
McKinsey & Company,
 
                                       36
<PAGE>   41
 
Inc. and Boston Consulting Group, Inc.), and Internet professional services
providers (e.g., USWeb/CKS, Viant Corporation, Scient Corporation and iXL
Enterprises, Inc.) -- many of which have considerably more financial resources,
marketing depth and name recognition than Proxicom. Occasionally Proxicom
competes with newer entrants including interactive marketing firms (e.g.,
Agency.com, Ltd. and Modem Media.Poppe Tyson, Inc.). Proxicom expects future
consolidation in the Internet professional services market to create larger,
more viable competitors. Potential clients' internal information systems groups
also compete with Proxicom.
 
     Proxicom believes the principal competitive factors in the Internet
professional services market include Internet expertise and talent, client
references, integrated strategy, technology and creative design services,
quality, pricing and speed of service delivery and vertical industry knowledge.
Proxicom believes it competes favorably with respect to these factors. Proxicom
believes it is in a good position to attract talent with its growth and an
entrepreneurial culture. Proxicom believes it offers its clients a unique
combination of integrated strategy, technology and creative design services. In
addition, Proxicom believes it has established itself as a leader in
Internet-specific industry and domain expertise. Through its replicable solution
frameworks and its attention to client satisfaction, Proxicom has created a
strong track record of customer successes. Proxicom believes the market will
continue to offer significant opportunity for multiple players.
 
INTELLECTUAL PROPERTY RIGHTS
 
     Proxicom's success is dependent, in part, upon its proprietary Proxicom
Process, its solution components, and other intellectual property rights. We do
not have any patents or patent applications pending. Proxicom relies on a
combination of trade secret, nondisclosure and other contractual agreements, and
copyright and trademark laws to protect its proprietary rights. Existing trade
secret and copyright laws afford us only limited protection. Proxicom enters
into confidentiality agreements with its employees, generally requires that its
consultants and clients enter into such agreements, and limits access to and
distribution of Proxicom's proprietary information. There can be no assurance
that the steps Proxicom has taken in this regard will be adequate to deter
misappropriation of its proprietary information or that Proxicom will be able to
detect unauthorized use and take appropriate steps to enforce its intellectual
property rights.
 
     Proxicom's business generally involves the development of software
applications for specific client engagements. Ownership of such software is
frequently assigned to the client, with Proxicom retaining a license or other
contractual rights for limited uses.
 
FACILITIES
 
     Proxicom's headquarters and principal administrative, finance, legal, sales
and marketing operations are located in approximately 65,000 square feet of
leased office space in Reston, VA. Proxicom's lease is for a term of seven years
and expires on July 13, 2002. The building is beneficially owned by Mario M.
Morino, one of our stockholders and a member of our board of directors. Proxicom
also leases office space in San Francisco, CA, New York, NY, Munich, Germany,
Sacramento, CA, Chicago, IL and Houston, TX. Proxicom expects that it will need
additional space as it expands its business and believes that it will be able to
obtain space as needed.
 
LEGAL PROCEEDINGS
 
     Proxicom is not a party to any material legal proceedings.

After this offering closes, General Atlantic Partners 34 and 52, GAP
Coinvestment and GAP Coinvestment II will be entitled to one demand registration
right under the Securities Act, subject to limitations. This means they can
demand that Proxicom register the sale of shares. In addition, all stockholder
parties will be entitled to piggyback registration rights as to the registration
of the sale of their shares of common stock under the Securities Act. In the
event that Proxicom proposes to register any shares of its common stock under
the Securities Act, either for its account or for the account of other security
holders, the holders of shares to be registered are entitled to receive notice
of the registration and are entitled to include their shares in it. The
underwriters of an offering can limit the number of shares of common stock held
by security holders with registration rights to be included in the registration.
 
OTHER TRANSACTIONS
 
     In December 1995, Proxicom loaned $155,000 to a partnership owned by Mr.
Fernandez. The partnership purchased computer equipment with the borrowed funds
and leased the equipment to Proxicom. The partnership ceased operations in 1997
and all assets and liabilities of the partnership were transferred to Proxicom
at book value of approximately $90,000.
 
     In February 1997, Proxicom leased approximately 65,000 square feet of
office space in Reston, VA. The lessor is 11600 Sunrise Limited Partnership, a
limited partnership of which Mario M. Morino, a Proxicom director and
stockholder, is the general partner. The lease term commenced on July 1, 1997
and has a seven-year term. Lease payments totaled approximately $331,000 for
1997 and $864,000 for 1998 and will increase at an annual rate of 3%.
 
     We believe that all transactions disclosed above were made on terms no less
favorable to Proxicom than would have been obtained from unaffiliated third
parties.

                       PRINCIPAL AND SELLING STOCKHOLDERS
 
   
     The following table presents information regarding the beneficial ownership
of common stock as of April 16, 1999 and as adjusted to reflect the sale of
common stock in this offering by:
    
 
     -  each person (or group of affiliated persons) who is the beneficial owner
        of more than 5% of the outstanding common stock;
 
     -  each of the named executive officers;
 
     -  each Proxicom director;
 
     -  all of the executive officers and directors as a group; and
 
     -  each selling stockholder.
 
   
     The persons named in this table have sole voting power for all shares of
common stock shown as beneficially owned by them, subject to community property
laws where applicable and except as indicated in the footnotes to this table.
Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission, or SEC. In computing the number of shares
beneficially owned by a person and the percentage ownership of that person,
shares of common stock subject to options held by that person that are currently
exercisable or exercisable within 60 days after April 16, 1999, are deemed
outstanding. Such shares, however, are not deemed outstanding for the purpose of
computing the percentage ownership of any other person.
    
 
     The "Beneficial Ownership After the Offering" share numbers and percentages
assume that the option granted to the underwriters to purchase additional shares
is not exercised.

dividends, if any, as the board of directors may declare out of funds legally
available, subject to any preferential dividend rights of any then-outstanding
preferred stock. Upon the liquidation, dissolution or winding up of Proxicom,
the holders of common stock are entitled to receive ratably the net assets of
Proxicom available after the payment of all debts and other liabilities and
subject to the prior rights of any then-outstanding preferred stock. Holders of
the common stock have no preemptive, subscription, redemption or conversion
rights. The outstanding shares of common stock are, and the shares offered by
Proxicom in the offering will be, when issued in consideration for payment,
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 Proxicom may
designate and issue in the future. See "-- Preferred Stock."
 
PREFERRED STOCK
 
   
     As of the date of this prospectus, Proxicom had outstanding an aggregate of
4,231,194 shares of preferred stock, consisting of 2,233,847 shares of Series A
convertible preferred stock, 359,712 shares of Series B convertible preferred
stock, 419,302 shares of Series C convertible preferred stock and 1,218,333
shares of Series D convertible preferred stock. All of these shares will
automatically convert to common stock, on a one share for one share basis,
immediately prior to this offering's closing.
    
 
     Following the closing of this offering, the board of directors will be
authorized, without further stockholder approval, to issue from time to time up
to an aggregate of 10,000,000 shares of preferred stock in one or more series.
The board of directors may fix or alter the designations, preferences, rights
and any qualification, limitations or restrictions of the shares of any series,
including the dividend rights, dividend rates, conversion rights, voting rights,
redemption terms and prices, liquidation preferences and the numbers of shares
constituting any series. As of the closing of this offering, no shares of
preferred stock will be outstanding. Although the ability of the board of
directors to designate and issue preferred stock could provide flexibility in
possible acquisitions or other corporate purposes, issuance of preferred stock
may have adverse effects on the holders of common stock. The effects include
 
     -   restrictions on dividends on the common stock if dividends on the
         preferred stock have not been paid;
 
     -   dilution of voting power of the common stock to the extent the
         preferred stock has voting rights; or
 
                                       48
<PAGE>   53
 
     -   deferral of participation in Proxicom's assets upon liquidation until
         satisfaction of any liquidation preference granted to holders of the
         preferred stock.
 
In addition, issuance of preferred stock could make it more difficult for a
third party to acquire a majority of the outstanding voting stock and
accordingly may be used as an "anti-takeover" device. The board of directors,
however, currently does not contemplate the issuance of any preferred stock and
is not aware of any pending transactions that would be affected by such
issuance.
 
ANTI-TAKEOVER EFFECTS OF PROXICOM'S CERTIFICATE OF INCORPORATION AND BYLAWS AND
PROVISIONS OF DELAWARE LAW
 
     Proxicom's certificate of incorporation and bylaws and provisions of
Delaware corporate law may hinder or delay a third party's attempt to acquire
Proxicom. They may also make it difficult for the stockholders to remove
incumbent management.
 
     Classified Board of Directors; Removal; Vacancies.  The certificate of
incorporation divides the board of directors into three classes. The directors
in each class serve three-year terms. The directors' terms are staggered by
class. Proxicom's classified board of directors is intended to provide
continuity and stability in the board of director's membership and policies.
However, the classified board of directors makes it more difficult for
stockholders to change the board of directors' composition quickly. Also, under
the certificate of incorporation, directors may be removed only for cause by a
two-thirds stockholder vote. In addition, a majority of the directors then in
office can fill board vacancies and newly created directorships resulting from
any increase in the size of the board of directors. This is true even if those
directors do not constitute a quorum or if only one director is left in office.
These provisions could prevent stockholders, including parties who want to take
over or acquire Proxicom, from removing incumbent directors without cause and
filling the resulting vacancies with their own nominees.
 
     Advance Notice Provisions for Stockholder Proposals and Stockholder
Nominations of Directors.  The bylaws will establish an advance notice procedure
regarding nominations of directors by stockholders and other stockholder
proposals. The advance notice procedure will not apply to nominations of
directors by the board of directors. For matters a stockholder wishes to bring
before an annual meeting of stockholders, the stockholder must deliver Proxicom
notice not less than 60 days nor more than 90 days before the first anniversary
of the preceding year's annual meeting of nominations and other business to be
brought before a Proxicom annual meeting. The stockholder must put information
in the notice regarding
 
     -  the stockholder and its holdings;
 
     -  the background of any nominee for director;
 
     -  the written consent to being named as a nominee and to serving as a
        director if elected;
 
     -  any business desired to be brought before the meeting;
 
     -  the reasons for conducting the business at the meeting; and
 
     -  any material interest of the stockholder in the business proposed.
 
     At a special meeting of stockholders called to elect directors,
stockholders can make a nomination only if they deliver to Proxicom a notice
that complies with the above requirements to Proxicom no later than the tenth
day following the day on which public announcement of the special meeting is
made. The bylaws could preclude a nomination for the election of directors or
the conduct of certain business at a particular meeting if the proper procedures
are not followed. This may discourage or deter a third party from conducting a
solicitation of proxies to elect its own slate of directors or otherwise
attempting to obtain control of Proxicom.
 
     Special Stockholders' Meetings.  Proxicom's certificate of incorporation
and bylaws will permit special meetings of the stockholders to be called only by
the board of directors, the
 
                                       49
<PAGE>   54
 
Chairman, the Chief Executive Officer or the President or holders of at least
75% of Proxicom's securities that are outstanding and entitled to vote in an
election of directors.
 
     Limitations on Stockholder Action by Written Consent.  The certificate of
incorporation will place limits on the stockholders' ability to act by written
consent. Specifically, any action to be taken at a stockholders' meeting may be
taken without a meeting only if consented to generally by stockholders having
voting power of at least 75% of the voting power of all shares of each class or
series entitled to vote on the action.
 
     Authorized But Unissued Shares.  Proxicom without stockholder approval can
issue shares of common stock and preferred stock up to the number of shares
authorized for issuance in its certificate of incorporation, except as limited
by Nasdaq rules. Proxicom could use these additional shares for a variety of
corporate purposes. These purposes include future public offerings to raise
additional capital, corporate acquisitions and employee benefit plans.
Proxicom's ability to issue these shares of common stock and preferred stock
could make it more difficult or discourage an attempt to obtain control of
Proxicom by means of a proxy contest, tender offer, merger or otherwise.
 
     Section 203 of Delaware Law.  After this offering is completed, Section 203
of the Delaware General Corporation Law will apply to Proxicom. This section
will prohibit Proxicom from engaging in a "business combination" with an
"interested stockholder." This restriction will apply for three years after the
date of the transaction in which the person became an interested stockholder,
unless the business combination is approved in a prescribed manner. A "business
combination" includes (1) mergers, (2) asset sales and (3) other transactions
resulting in a financial benefit to an interested stockholder. Generally, an
"interested stockholder" is a person who, together with affiliates and
associates, owns, or within three years did own, 15% or more of Proxicom's
voting stock. Section 203 could delay, defer or prevent a change in control of
Proxicom. It might also reduce the price that investors might be willing to pay
in the future for shares of common stock.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
     The certificate of incorporation will provide that directors of Proxicom
shall not be personally liable to Proxicom or its stockholders for monetary
damages for breach of fiduciary duty as a director, except for liability (1) for
any breach of the director's duty of loyalty to Proxicom or its stockholders,
(2) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (3) under a provision of Delaware law
relating to unlawful payment of dividends or unlawful stock purchase or
redemption of stock or (4) for any transaction from which the director derives
an improper personal benefit. As a result of this provision, Proxicom and its
stockholders may be unable to obtain monetary damages from a director for breach
of his or her duty of care.
 
     The bylaws will provide for the indemnification of directors and officers
and any person who is or was serving at the request of Proxicom as a director,
officer, employee, partner or agent of another corporation or of a partnership,
joint venture, limited liability company, trust or other enterprise to the
fullest extent authorized by, and subject to the conditions set forth in, the
Delaware General Corporation Law against all expenses, liabilities and losses.
The indemnification provided under the bylaws will include the right to be paid
by Proxicom the expenses in advance of any proceeding for which indemnification
may be had in advance of its final disposition.
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the common stock is the Bank of New
York.

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

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Sales of substantial amounts of our common stock in the public market could
adversely affect our common stock's prevailing market price. Upon completion of
this offering, we will have outstanding an aggregate of 23,901,103 shares of our
common stock, assuming no exercise of the underwriters over-allotment option and
no exercise of outstanding options. Of these shares, all of the shares sold in
this offering will be freely tradable without restriction or further
registration under the Securities Act, unless the shares are purchased by
"affiliates" of Proxicom as that term is defined in Rule 144 under the
Securities Act.
    
 
   
     The remaining 19,401,103 shares of common stock held by existing
stockholders are "restricted securities" as that term is defined in Rule 144
under the Securities Act. Restricted securities may be sold in the public market
only if registered or if they qualify for an exemption from registration under
Securities Act Rule 144 or 701. We summarize these two rules below. The
provisions of Rules 144 and 701 provide that the restricted securities will be
available for sale in the public market on the date which is one year from the
date they were issued, subject to the volume limitations and other conditions of
Rule 144.
    
 
LOCK-UP AGREEMENTS
 
   
     All of Proxicom's officers and directors, and several of its stockholders,
who will own an aggregate of 19,769,412 shares (of which 1,305,454 shares are
issuable upon the exercise of options) of common stock after this offering
closes, have signed lock-up agreements. Under these agreements, they agreed,
among other things, not to transfer or dispose of any shares of common stock, or
any securities convertible into shares of common stock, for a period of 180 days
after the date of this prospectus. Transfers or dispositions can be made sooner
with the prior written consent of BT Alex. Brown Incorporated. This consent may
be given at any time without public notice.
    
 
RULE 144
 
   
     Under Rule 144, 12,267,700 shares of common stock will be freely tradable
90 days after this offering closes. Of these shares of common stock, 11,507,439
shares are subject to lock-up agreements. In general, under Rule 144, beginning
90 days after the closing of this offering, a person who has owned shares of our
common stock for at least one year would be entitled to sell within any
three-month period a number of shares that does not exceed the greater of:
    
 
   
     -  one percent of the number of shares of common stock then outstanding,
        which will equal approximately 239,011 shares immediately after this
        offering; or
    
 
     -  the average weekly trading volume of the common stock on the Nasdaq
        National Market during the four calendar weeks preceding the filing of a
        notice on Form 144 with respect to such sale.
 
Sales under Rule 144 are also subject to manner of sale provisions and notice
requirements and to the availability of current public information about
Proxicom.
 
     Under Rule 144(k), 23,981 shares of common stock will be freely tradable
after this offering closes. None of these shares of common stock are subject to
lock-up agreements. Under Rule 144(k), a person who is not one of our affiliates
at any time during the 90 days preceding a sale, and who has owned the shares
proposed to be sold for at least two years, is entitled to sell the shares
without complying with the manner of sale, public information, volume limitation
or notice provisions of Rule 144. Therefore, unless otherwise restricted, "Rule
144(k) shares" may be sold immediately upon the completion of this offering.

<PAGE>   56
 
RULE 701
 
   
     As of March 26, 1999, a total of 5,185,662 shares of common stock had been
issued or were issuable upon the exercise of options. All of these shares,
subject to option vesting, will be eligible for sale in reliance on Rule 701
beginning 90 days after the closing of this offering. Of these shares of common
stock, 1,380,454 are subject to lock-up agreements. In general, under Rule 701
as currently in effect, any of our employees, consultants or advisors who has
purchased shares from us in connection with a compensatory plan or other
agreement is eligible to resell such shares 90 days after the effective date of
this offering in reliance on Rule 144, but without compliance with restrictions,
including the holding period, contained in Rule 144.
    
 
REGISTRATION RIGHTS
 
     Upon completion of this offering, Proxicom stockholders, who will own an
aggregate of 19,056,133 shares of common stock, will have registration rights as

to lock-up agreements. GAP 34, GAP 52, GAP Coinvestment and GAP Coinvestment II,
who will own an aggregate of 3,913,664 shares of our common stock, or their
transferees, will be entitled to demand that Proxicom register their shares. In
addition, all of the Proxicom stockholders who have registration rights are
entitled to piggyback registration. See "Certain Transactions -- Registration
Rights Agreement." After registration, these shares will be freely tradable
without restriction under the Securities Act, unless the shares are purchased by
affiliates. Any sales of securities by these stockholders could have a material
adverse effect on the trading price of our common stock.
 
STOCK PLANS
 
     As soon as practicable after this offering, we intend to file a
registration statement under the Securities Act covering 8,350,000 shares of
common stock reserved for issuance under our stock plans. As of March 26, 1999,
options to purchase 4,977,347 shares of common stock were outstanding. The
registration statement is expected to be filed and become effective as soon as
practicable after the effective date of this offering. Accordingly, shares
registered under such registration statement will, subject to vesting provisions
and Rule 144 volume limitations applicable to our affiliates, be available for
sale in the open market shortly after this offering closes, and in the case of
our officers, directors and stockholders who have entered into lock-up

     The underwriters are obligated to purchase all of the shares of common
stock offered hereby, other than those covered by the over-allotment option
described below, if any such shares are purchased.
 
     The underwriters propose to offer the shares of common stock to the public
at the public offering price set forth on the cover page of this prospectus and
to some dealers at a price that represents a concession not in excess of $
per share under the public offering price. The underwriters may allow, and such
dealers may re-allow, a concession not in excess of $     per share to other
dealers. After the initial offering, the offering price and other selling terms
may be changed by the representatives of the underwriters.
 
     Proxicom has granted to the underwriters an option, exercisable not later
than 30 days after the date of this prospectus, to purchase up to 675,000
additional shares of common stock at the public offering price less the
underwriting discounts and commissions set forth on the cover page of this
prospectus. The underwriters may exercise such option only to cover
over-allotments made in connection with the sale of the common stock offered
hereby. To the extent that the underwriters exercise such options, each of the
underwriters will become obligated, subject to conditions, to purchase
approximately the same percentage of additional shares of common stock as the
number of shares of common stock to be purchased by it in the above table bears
to 675,000. Proxicom will be obligated, pursuant to the option, to sell such
shares to the underwriters to the extent the option is exercised. If any
additional shares of common stock are purchased, the underwriters will offer
additional shares on the same terms as those on which the shares are being
offered.

underwriters by the Proxicom and the selling stockholders, and the expenses

     At our request, the underwriters have reserved for sale, at the initial
public offering price, up to 10% of the shares of the common stock offered
hereby for purchase by our directors, officers and employees and their business
associates and related persons. The number of shares of our common stock offered
to the public will be reduced to the extent these persons purchase such reserved
shares. The underwriters will offer to the public on the same basis as the other
shares offered hereby any reserved shares which are not so purchased by these
persons.
 
     Proxicom has agreed to indemnify the underwriters against liabilities in
connection with this offering, including liabilities under the Securities Act.
 
     Each of Proxicom's officers and directors and Proxicom's larger
stockholders have agreed not to offer, sell, contract to sell or otherwise
dispose of, or enter into any transaction which is designed to, or could be
expected to, result in the disposition of any portion of, any common stock for a
period of 180 days after the effective date of the registration statement of
which this prospectus is a part without the prior written consent of BT Alex.
Brown Incorporated. This consent may be given at any time without public notice.
 
     Proxicom has entered into a similar agreement, except that we may issue,
and grant options or warrants to purchase, shares of common stock or any
securities convertible into, exercisable for or exchangeable for shares of
common stock, pursuant to the exercise of outstanding options and warrants and
our issuance of options and stock granted under the existing stock option and
stock purchase plans.
 
     The representatives of the underwriters have advised Proxicom that the
underwriters do not intend to confirm sales to any account over which they
exercise discretionary authority.
 
     In order to facilitate the offering of the common stock, the underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
market price of the common stock. Specifically, the underwriters may over-allot
shares of the common stock in connection with this offering, thereby creating a
short position in the common stock for their own account. Additionally, to cover
such over-allotments or to stabilize the market price of the common stock, the
underwriters may bid for, and purchase, shares of the common stock in the open
market. Finally, the representatives, on behalf of the underwriters, also may
reclaim selling concessions allowed to an underwriter or dealer if the
underwriting syndicate repurchases shares distributed by that underwriter or
dealer. Any of these activities may maintain the market price of our common
stock at a level above that which might otherwise prevail in the open market.
The underwriters are not required to engage in these activities and, if
commenced, may end any of these activities at any time.
 
   
     Thomas Weisel Partners LLC, one of the representatives of the underwriters,
was organized and registered as a broker-dealer in December 1998. Since December
1998, Thomas Weisel Partners has been named as a lead or co-manager on 20 filed
public offerings of equity securities, of which six have been completed, and has
acted as a syndicate member in an additional eight public offerings of equity
securities. Thomas Weisel Partners does not have any material relationship with
us or any of our officers, directors or controlling persons, except that Jack
Kemp is a member of Proxicom's board of directors and a member of the advisory
board of Thomas Weisel Partners and except with respect to the contractual
relationship created by the underwriting agreement.

PRICING OF THIS OFFERING
 
     Prior to this offering, there has been no public market for our common
stock. Consequently, the initial public offering price for our common stock will
be negotiated among Proxicom, the
 
                                       54
<PAGE>   59
 
selling stockholders and the representatives of the underwriters. Among the
factors to be considered in determining the public offering price will be:
 
     - the history and prospects of Proxicom's business and the industry in
       which it competes;
 
     - an assessment of Proxicom's management and the present state of
       Proxicom's development;
 
     - prevailing market conditions in the U.S. economy and the industry in
       which Proxicom competes;
 
     - Proxicom's revenues, operating cash flow and earnings in recent periods;
 
     - the market capitalizations and stages of development of other companies
       which the representatives of the underwriters believe to be comparable to
       Proxicom; and
 
     - estimates of Proxicom's business potential.
 
                                 LEGAL MATTERS
 
     The validity of the shares of common stock being offered hereby and other
legal matters will be passed upon for Proxicom by Hogan & Hartson L.L.P.,
Washington, D.C. Legal matters in connection with the offering will be passed
upon for the underwriters by Hale and Dorr LLP, Washington, D.C.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Stockholders and Board of Directors
of Proxicom, Inc.
 
     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of operations, of changes in stockholders'
equity and of cash flows present fairly, in all material respects, the financial
position of Proxicom, Inc. (the "Company") and its subsidiaries at December 31,
1998 and 1997, and the results of their operations and their cash flows for each
of the three years in the period ended December 31, 1998, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.
 
     As described in Note 2, on March 26, 1999, Proxicom, Inc. merged with ad
hoc Interactive, Inc. in a transaction accounted for as a pooling of interests.
The accompanying supplemental consolidated financial statements give retroactive
effect to the merger of Proxicom, Inc. with ad hoc Interactive, Inc.
 
     In our opinion, based upon our audits, the accompanying supplemental
consolidated balance sheets and the related supplemental consolidated statements
of operations, of changes in stockholders' equity and of cash flows present
fairly, in all material respects, the financial position of Proxicom, Inc. and
its subsidiaries at December 31, 1998 and 1997, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1998, in conformity with generally accepted accounting principles.
These financial statements are the responsibility of the Company's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which 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,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  NATURE OF OPERATIONS
 
     Proxicom, Inc. ("Proxicom") is a leading provider of Internet solutions to
Global 1000 companies and other large organizations. Since 1994, Proxicom has
focused exclusively on the Internet. Proxicom's Internet solutions include
business to consumer electronic commerce Internet sites, business to business
electronic commerce extranets, and company-specific intranets.
 
     In August 1996, Proxima, Inc. ("Proxima"), a Maryland corporation
reincorporated as a Delaware corporation, through a merger transaction, changing
its name to Proxicom, Inc.
 
     Renaissance Leasing Corp. ("Renaissance") was a partnership substantially
owned by the majority stockholder of Proxicom. Renaissance purchased computer
equipment with funds borrowed from Proxicom and leased all such assets to
Proxicom. Renaissance ceased operations in 1997 and all assets and liabilities
of Renaissance were transferred to Proxicom at book value of approximately
$90,000. Proxicom and Renaissance were companies under common control and have
been accounted for in a manner similar to a pooling of interests.
 
2.  MERGERS
 
     In August 1998, Proxicom completed a merger with IBIS Consulting, Inc.
("IBIS Consulting"), a Subchapter S Corporation incorporated during 1994, by
exchanging 4,988,297 shares of Proxicom's common stock for all the common stock
of IBIS Consulting. Each share of IBIS Consulting was exchanged for 0.2327868
shares of Proxicom common stock. In addition, outstanding IBIS Consulting
employee stock options were converted at the same exchange factor into options
to purchase 345,034 shares of Proxicom common stock (Note 9).
 
     There were no transactions between Proxicom and IBIS Consulting prior to
the combination. No material adjustments were made to conform to Proxicom's
accounting policies.
 
     Effective January 1, 1998, Proxicom completed a merger with Square Earth,
Inc. ("Square Earth"), a Subchapter S Corporation incorporated during 1996, by
exchanging 534,999 shares of its common stock for all the common stock of Square
Earth. Each share of Square Earth was exchanged for 0.445833 shares of Proxicom
common stock. In addition, outstanding Square Earth employee stock options were
converted at the same exchange factor into options to purchase 41,474 shares of
Proxicom common stock (Note 9).
 
     There were no transactions between Proxicom and Square Earth prior to the
combination. No material adjustments were made to conform to Proxicom's
accounting policies.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The IBIS Consulting and Square Earth mergers constituted tax-free
reorganizations and have been accounted for as poolings of interests under
Accounting Principles Board Opinion No. 16, Business Combinations. Accordingly,
all prior period consolidated financial statements presented have been restated
to include the combined results of operations, financial position and cash flows
of IBIS Consulting and Square Earth as though they had been a part of Proxicom
since their inception.
 
     Proxicom incurred charges of approximately $2.9 million in 1998 for costs
associated with the IBIS Consulting and Square Earth transactions. Those
transaction costs related to professional fees and other direct expenses
relating to the acquisitions.
 
3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
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 amounts reported in the consolidated financial
statements. Actual results may differ from those estimates.
 
PRINCIPLES OF CONSOLIDATION
 
     The accompanying consolidated financial statements include the accounts and
balances of Proxicom, IBIS Consulting, Square Earth and Renaissance (hereafter
collectively the "Company" or "Proxicom"). All significant intercompany
transactions and balances have been eliminated in consolidation.
 
CASH AND CASH EQUIVALENTS
 
     Highly liquid investments having original maturities of 90 days or less at
the date of acquisition are classified as cash equivalents. The carrying values
of cash equivalents approximate fair values.
 
REVENUE RECOGNITION
 
   
     Revenue from Internet professional services are recognized based on the
nature of the contract. Revenue from fixed-price contracts is recognized using
the percentage-of-completion method based on the ratio of costs incurred to
total estimated costs. Revenue from time-and-materials contracts is accounted
for as time is incurred and billed. Net revenues exclude reimburseable expenses
charged to clients.
    
 
     The Company periodically evaluates cost and revenue assumptions in
fixed-price contracts. Provisions for estimated losses on uncompleted contracts
are made on a contract by contract basis and are recognized in the period in
which such losses are determined. Most contracts are cancellable by either the
Company or the customer upon 30 days notice, with payment due for services
completed through the date of termination. No significant losses have been
incurred on cancelled contracts.
 
     Deferred revenue is recognized on fixed-price contracts to reflect billings
in excess of revenue recognized under the percentage-of-completion method.
 
                                       F-8
<PAGE>   69
                                 PROXICOM, INC.
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Unbilled services on contracts are comprised of costs plus earnings in
excess of contractual billings on such contracts. Billings in excess of cost
plus earnings are classified as deferred revenue.
 
RESEARCH AND DEVELOPMENT EXPENSES FOR SOFTWARE PRODUCTS
 
     Research and development costs are expensed as incurred. Statement of
Financial Accounting Standards ("SFAS") No. 86, Accounting for the Costs of
Computer Software to be Sold, Leased or Otherwise Marketed, requires
capitalization of certain software development costs subsequent to the
establishment of technological feasibility and prior to general release of the
software. Based on the Company's development process, technological feasibility
is established upon completion of a working model. The period between
technological feasibility and general release is relatively short and the costs
incurred during this period have been insignificant for capitalization.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment are stated at cost. Depreciation and amortization
are computed on the straight-line method over the estimated useful lives of the
related assets ranging from three to five years. Leasehold improvements are
amortized on a straight-line method over the shorter of the improvements'
estimated useful lives or related remaining lease term. Long-lived assets held
and used by the Company are reviewed for impairment whenever changes in
circumstances indicate the carrying value of an asset may not be recoverable.
 
INVESTMENTS
 
     The Company classifies its investments as available-for-sale as defined by
SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities.
Available-for-sale securities are carried at fair value, with the unrealized
gains and losses, net of taxes, reported as comprehensive income within
stockholders' equity. Comprehensive income is not materially different from net
income in any period presented.
 
INCOME TAXES
 
     The provision for income taxes is determined in accordance with SFAS No.
109, Accounting for Income Taxes, which requires the use of the asset and
liability approach. Under this approach, deferred taxes represent the expected
future tax consequences of temporary differences between the carrying amounts
and tax bases of assets and liabilities.
 
STOCK-BASED COMPENSATION
 
     The Company accounts for stock-based employee compensation arrangements in
accordance with provisions of Accounting Principles Board ("APB") Opinion No.
25, Accounting for Stock Issued to Employees, and complies with the disclosure
provisions of SFAS No. 123, Accounting for Stock-Based Compensation. Under APB
No. 25, compensation expense is based on the difference, if any, on the date of
the grant, between the fair value of the Company's stock and the exercise price.
A new measurement date for purposes of determining compensation is established
when there is a substantive change to the terms of an underlying option. See
Note 9.

RECENT ACCOUNTING PRONOUNCEMENTS
 
     During 1998, the Company adopted FAS 131, Disclosures About Segments of An
Enterprise and Related Information. This Statement changes the way public
companies report information about segments of their business in annual
financial statements and requires disclosure of selected segment information. It
also requires entity-wide disclosures about the products and services an entity
provides, the material countries in which it holds assets and reports revenues,
and its major customers. The Company currently operates in one operating and
geographic segment. The adoption of SFAS No. 131 does not have a material effect
on the current reporting or disclosure requirements.
 
     In June 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities. This statement requires companies to record
derivatives on the balance sheet as assets or liabilities, measured at fair
value. Gains or losses resulting from changes in the values of those derivatives
would be accounted for depending on the use of the derivative and whether it
qualifies for hedge accounting. SFAS No. 133 will be effective for the Company's
fiscal year

     In July 1998, IBIS Consulting entered into a line of credit with a bank in

     In October 1998, the Company entered into a $10.0 million revolving line of

terminated. The use of the line generally is restricted to working capital
requirements and approved acquisitions as defined in the line of credit
agreement. Interest on this line is payable on a monthly basis at a variable
rate of LIBOR plus 2%. The line of credit is secured by the Company's
consolidated real and personal property, including intellectual property rights
and all cash and non-cash proceeds of these assets. Included in the line of
credit are various customary financial and other covenants including maintenance
of a minimum level of tangible net worth. The line of credit expires on August

$205,000 which reduce amounts available under the line. Borrowings of $5.4
million and $4.4 million were outstanding and available, respectively, against
the line as of December 31, 1998.

     Interest expense was $33,000, $94,000 and $227,000 for the years ended

matures in the earlier of August 21, 1999 or upon completion of an initial
public offering. This unsecured note is subordinated only to the Company's
senior bank facilities.
 
9.  STOCK OPTION PLANS
 
PROXICOM STOCK OPTION PLANS FOR EMPLOYEES AND NON-EMPLOYEES
 
     In 1996, Proxicom established a stock option plan (the "Plan") under which
eligible employees and eligible non-employees may be granted options to purchase
shares of the Company's common stock. The Plan provides for the issuance of a
maximum of 4,150,000 shares of common stock. Under the Plan, the option purchase
price for each grant is equal to the fair value of the common stock at the date
of the grant as determined by the Board of Directors. Options granted under the
plan generally vest ratably over a four-year period and expire 10 years from the
date of the grant.
 
IBIS CONSULTING
 
     In January and August 1997, IBIS Consulting granted options to two key
employees to purchase 1,759,031 shares with an exercise price of $0.219 per
share. Options for 1,496,494 shares became exercisable upon grant, with the
remaining 262,537 shares vesting over a two-year period commencing January 1,
1999. Under the terms of the option agreement, prior to the completion of an
initial public offering or sale of IBIS Consulting, IBIS Consulting was required
to repurchase and the employee was required to sell the shares or vested options
upon

termination of employment, based on a pre-determined formula. After exercise,
IBIS Consulting retained the right and obligation to reacquire the shares based
on the formula price upon termination of the employee prior to the completion of
an initial public offering or sale of IBIS Consulting.
 
     In July 1998, one employee exercised his option to acquire 1,496,494
shares. The employee paid IBIS Consulting $330,000 to exercise the options and
received $275,000, less applicable taxes under a tax reimbursement cash bonus
arrangement.
 
     The Company recognized compensation expense in 1997 and a liability related
to both these options and the underlying cash bonus arrangement in the amount of
$220,000.
 
     In January 1997, IBIS Consulting granted options to purchase 256,065 shares
to another employee with an exercise price of $0.403 per share. These options
were subject to a vesting schedule. Employment was terminated in 1997 and the
unvested options lapsed upon termination.
 
     In January 1998, IBIS Consulting announced the grant of options under a
1998 plan and the conversion of options outstanding under the 1997 plan. In July
1998, IBIS Consulting granted such options to employees covering 82,497 shares
with an exercise price of $4.72 per share. The options are subject to an
18-month vesting schedule. Concurrent with this 1998 option grant, the remaining
1997 options of 262,537 shares were converted to the 1998 Plan. IBIS
Consulting's previous obligation to repurchase and the employees obligation to
sell the vested options upon termination of employment was eliminated.
 
     In connection with the Company's merger with IBIS Consulting, the Company
assumed all outstanding options to purchase shares of common stock of IBIS
Consulting. These options were converted into options to purchase equivalent
shares of the Company's common stock based on the merger exchange formula and
subsequently included under the Plan.
 
SQUARE EARTH, INC.
 
     In connection with the Company's merger with Square Earth, the Company
assumed all outstanding options to purchase shares of common stock of Square
Earth. These options were converted into options to purchase equivalent shares
of the Company's common stock based on the merger exchange formula and
subsequently included under the Plan.

     In early 1997, prior to Proxicom's investment in IBIS Consulting, IBIS
Consulting entered into an arrangement with an employee providing that
individual with 1,496,494 fully vested stock options which were subject to
certain conditions, including provisions requiring IBIS Consulting to buy back
the common stock resulting from exercise of the options and requiring the
employee to sell such shares to IBIS Consulting at a pre-determined formula upon
termination of employment. The employee exercised these options in July 1998.
Due to a change of control provision in the initial option agreement, concurrent
to the merger of IBIS Consulting and Proxicom, the repurchase requirement on the
stock and stock options was eliminated allowing the employees to freely trade
the stock.
 
     As a consequence of the above change of control provision triggered by the
merger, and the conversion of options from the 1997 plan to the 1998 plan, the
Company recorded non-cash stock-based compensation of approximately $17.0
million equal to the difference between the pre-determined formula price and the
then fair value of the underlying stock or stock options. As

the shares were fully vested, the compensation expense was recognized at the
time of the merger.
 
     In connection with other stock option grants during the year ended December
31, 1998, the Company recognized additional stock-based compensation totaling
$219,000, and deferred stock-based compensation which is being amortized through
December 31, 1999, the 18-month vesting period of the related options. The
Company did not recognize any amortization expense during the years ended
December 31, 1996 and 1997.
 
PROXICOM STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS
 
     In February 1997, the Company established a stock option plan for
non-employee directors (the "Directors Plan") and has reserved 350,000 shares of
common stock for issuance under the provisions of this plan. Options granted
prior to December 15, 1998 generally vest over the three-year term as a
director. Options under the Directors Plan issued subsequent to December 15,
1998 are expected to be issued on a fully vested basis. Options for 175,000
shares have been granted through December 31, 1998 under the Directors Plan.
 
ACCOUNTING FOR STOCK OPTIONS ISSUED TO EMPLOYEES AND NON-EMPLOYEE DIRECTORS
 
     The Company accounts for its stock options issued to employees and
non-employee directors in accordance with APB 25 under which compensation
expense of $0, $220,000, and $17.2 million was recognized for the options
granted in 1996, 1997 and 1998, respectively. The Company has provided
additional pro forma disclosures as required by SFAS No. 123, "Accounting for
Stock-Based Compensation."
 
     For disclosure purposes, the fair value of each stock option granted is
estimated on the date of grant using the Black-Scholes option-pricing model with
the following weighted average assumptions used for stock options granted in
1996, 1997 and 1998: no annual dividends, expected volatility of 0.0%, risk-free
interest rate ranging from 5.1% to 6.1% and expected life of one to four years.
The weighted-average fair values of the stock options granted in 1996, 1997 and
1998 were $0.75, $3.18 and $1.21, respectively.
 
     Under the above model, the total value of stock options granted in 1996,
1997 and 1998 were $490,000, $8.8 million and $2.4 million, respectively, which
would be amortized on a pro forma basis over the option vesting period. Had the
Company determined compensation cost for these plans in accordance with SFAS No.
123, the Company's pro forma net income (loss) would have been approximately
$1.1 million, ($635,000) and ($7.0 million) in 1996, 1997 and 1998,
respectively, and pro forma basic and diluted earnings per common share would
have been $0.08, ($0.05) and ($0.51) in 1996, 1997 and 1998, respectively.
 
ACCOUNTING FOR STOCK OPTIONS ISSUED TO NON-EMPLOYEES
 
     The Company accounts for its stock options granted to eligible
non-employees on the fair value method in accordance with SFAS No. 123.
Stock-based compensation related to non-employee stock option grants is not
material in any period presented.

     The weighted-average exercise prices for Proxicom options outstanding at
December 31, 1996, 1997 and 1998 were $3.30, $3.86 and $6.57, respectively and
exercise prices ranged from $3.30 to $4.78 at December 31, 1998. The
weighted-average exercise prices for IBIS Consulting options at December 31,
1997, and 1998 were $0.22 and $1.30 and exercise prices ranged from $0.22 to
$4.72 at December 31, 1998. These options will expire if not exercised at
specific dates ranging from January 1998 to December 2008 and the
weighted-average remaining contractual life of the options outstanding was

10.  CONVERTIBLE PREFERRED STOCK AND WARRANTS
 
     On August 30, 1996, the Company consummated a transaction whereby: (i) the
Company repurchased from the Company's Chief Executive Officer 100,917 shares of
common stock at a price of $3.27 per share, for a total purchase price of
approximately $330,000; and, (ii) the Company issued a total of 1,629,969 shares
of Series A convertible preferred stock (the "Series A Preferred Stock") at a
price of $3.27 per share, or approximately $5.3 million. At the stockholders'
option, but in any event automatically upon an initial public offering of the
Company's common stock, each share of Series A Preferred Stock will be
convertible into one share of common stock. The Series A Preferred Stock has a
liquidation preference and is not entitled to any dividends (unless cash
dividends are declared and paid on the common stock, in which case the Series A
Preferred Stock will share on an "as if" converted basis). The holders of

the Series A Preferred Stock have registration rights and are entitled to place
two persons on the Company's Board.
 
     One investor in the Series A Preferred Stock also received warrants to
purchase 1,011,378 additional shares of Series A Preferred Stock from the
Company at a price of $7.91 per share. The warrants expire in August 2003 and
are exercisable after December 31, 1997. After December 31, 1997, the warrants
may be converted into shares of common stock at the option of the warrant
holder. The conversion formula is based on the difference between the market
value of the common stock less the warrant exercise price divided by the market
value of the common stock. The value of the warrants was not material.
 
     In February 1997, the Company consummated a transaction whereby: (i) the
Company repurchased from the Company's Chief Executive Officer 359,712 shares of
common stock at a price of $4.17 per share, for a total purchase price of
approximately $1.5 million; (ii) the Company issued a total of 359,712 shares of
Series B convertible preferred stock (the "Series B Preferred Stock") at a price
of $4.17 per share or approximately $1.5 million. The Series B Preferred Stock
has essentially the same rights and privileges as the Series A Preferred Stock.
 
     In December 1997, the Company issued a total of 419,302 shares of Series C
convertible preferred stock (the "Series C Preferred Stock") at a price of $4.77
per share or approximately $2.0 million. The Series C Preferred Stock has
essentially the same rights and privileges as the Series A and B Preferred
Stock.
 
     In January 1998, the Company issued 407,500 shares of treasury stock in
conjunction with the conversion of 407,500 shares of Series A Preferred Stock
into common stock.
 
     In February 1999, the Company issued a total of 1,218,333 shares of Series
D convertible preferred stock (the "Series D Preferred Stock") at a price of
$6.00 per share or approximately $7.3 million. In connection with this
transaction, 758,667 shares of common stock were purchased by the investors from
selling stockholders in amounts proportionate to the investors participation in
the Series D Preferred Stock issuance. The Series D Preferred Stock has
essentially the same rights and privileges as the Series A, B and C Preferred
Stock. Because the Series D Preferred Stock was sold at a price of $6.00, such
securities will be accounted for giving effect to its beneficial conversion
features. Under such accounting, the Company will record a $4.9 million charge
against additional paid-in capital to reflect the difference between the
conversion feature and the estimated fair value of the underlying common stock.
Although not reflected on the statement of operations, the beneficial conversion
charge will be reflected as a reduction to income and earnings per share
available for common stockholders.

     SFAS No. 128 replaces fully diluted earnings per share with diluted net
income per share which reflects the potential dilution that could occur if
securities or other contracts to issue common stock were exercised or converted
into common stock or resulted in the issuance of common stock that then shared
in the earnings of the entity.
 
16.  PENDING INVESTMENT
 
   
     In December 1998, Proxicom executed a letter of intent to make a cash
investment of approximately $360,000 in a recently formed joint venture entity
in Italy (the "Entity") created by Ericsson Telecommunicazioni SpA ("Ericsson").
Proxicom will own 19.9% of the common stock of the Entity proportionate to its
investment in relation to the total Entity capitalization. The Entity was formed
to deliver Internet professional services in Italy. It is anticipated that the
Entity will contract with Proxicom for certain consulting services, at arm's
length market rates on a time and materials basis. Also the Entity will utilize
the "Proxicom Process," Proxicom's proprietary, multi-phase methodology, which
Ericsson will transfer to the Entity for a fee. Proxicom will not participate in
the management or policy making of the business. Inasmuch as Proxicom will not
have the ability to influence significantly the entity or is operations,
Proxicom intends to account for its investment on the cost basis. Proxicom also
will have an option to buy an additional 20.0% share in the common stock of the
Entity, subject to certain conditions and restrictions. In March and April 1999,
Proxicom signed final agreements relating to this transaction.

* Not applicable to reporting period.
 
     The IBIS Consulting, Ad Hoc and Square Earth mergers constituted tax-free
reorganizations and have been accounted for as poolings of interests under
Accounting Principles Board Opinion No. 16, Business Combinations. Accordingly,
all prior period consolidated financial statements presented have been restated
to include the combined results of operations, financial position and cash flows
of IBIS Consulting, Ad Hoc and Square Earth as though they had been a part of
Proxicom since their inception.
 
     Proxicom incurred charges of approximately $2.9 million in 1998 for costs
associated with the IBIS Consulting and Square Earth transactions. Those
transaction costs related to professional fees and other direct expenses
relating to the acquisitions.
 
3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
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 amounts reported in the consolidated financial
statements. Actual results may differ from those estimates.
 
PRINCIPLES OF CONSOLIDATION
 
     The accompanying supplemental consolidated financial statements include the
accounts and balances of Proxicom, IBIS Consulting, Square Earth, Ad Hoc and
Renaissance (hereafter collectively the "Company" or "Proxicom"). All
significant intercompany transactions and balances have been eliminated in
consolidation.
 
CASH AND CASH EQUIVALENTS
 
     Highly liquid investments having original maturities of 90 days or less at
the date of acquisition are classified as cash equivalents. The carrying values
of cash equivalents approximate fair values.

     NOTES TO SUPPLEMENTAL CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
REVENUE RECOGNITION
 
   
     Revenue from Internet professional services are recognized based on the
nature of the contract. Revenue from fixed-price contracts is recognized using
the percentage-of-completion method based on the ratio of costs incurred to
total estimated costs. Revenue from time-and-materials contracts is accounted
for as time is incurred and billed. Net revenues exclude reimburseable expenses
charged to clients.
    
 
     The Company periodically evaluates cost and revenue assumptions in
fixed-price contracts. Provisions for estimated losses on uncompleted contracts
are made on a contract by contract basis and are recognized in the period in
which such losses are determined. Most contracts are cancellable by either the
Company or the customer upon 30 days notice, with payment due for services
completed through the date of termination. No significant losses have been
incurred on cancelled contracts.
 
     Deferred revenue is recognized on fixed-price contracts to reflect billings
in excess of revenue recognized under the percentage-of-completion method.
 
     Unbilled services on contracts are comprised of costs plus earnings in
excess of contractual billings on such contracts. Billings in excess of cost
plus earnings are classified as deferred revenue.
 
RESEARCH AND DEVELOPMENT EXPENSES FOR SOFTWARE PRODUCTS
 
     Research and development costs are expensed as incurred. Statement of
Financial Accounting Standards ("SFAS") No. 86, Accounting for the Costs of
Computer Software to be Sold, Leased or Otherwise Marketed, requires
capitalization of certain software development costs subsequent to the
establishment of technological feasibility and prior to general release of the
software. Based on the Company's development process, technological feasibility
is established upon completion of a working model. The period between
technological feasibility and general release is relatively short and the costs
incurred during this period have been insignificant for capitalization.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment are stated at cost. Depreciation and amortization
are computed on the straight-line method over the estimated useful lives of the
related assets ranging from three to five years. Leasehold improvements are
amortized on a straight-line method over the shorter of the improvements'
estimated useful lives or related remaining lease term. Long-lived assets held
and used by the Company are reviewed for impairment whenever changes in
circumstances indicate the carrying value of an asset may not be recoverable.
 
INVESTMENTS
 
     The Company classifies its investments as available-for-sale as defined by
SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities.
Available-for-sale securities are carried at fair value, with the unrealized
gains and losses, net of taxes, reported as

     NOTES TO SUPPLEMENTAL CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
comprehensive income within stockholders' equity. Comprehensive income is not
materially different from net income in any period presented.
 
INCOME TAXES
 
     The provision for income taxes is determined in accordance with SFAS No.
109, Accounting for Income Taxes, which requires the use of the asset and
liability approach. Under this approach, deferred taxes represent the expected
future tax consequences of temporary differences between the carrying amounts
and tax bases of assets and liabilities.
 
STOCK-BASED COMPENSATION
 
     The Company accounts for stock-based employee compensation arrangements in
accordance with provisions of Accounting Principles Board ("APB") Opinion No.
25, Accounting for Stock Issued to Employees, and complies with the disclosure
provisions of SFAS No. 123, Accounting for Stock-Based Compensation. Under APB
No. 25, compensation expense is based on the difference, if any, on the date of
the grant, between the fair value of the Company's stock and the exercise price.
A new measurement date for purposes of determining compensation is established
when there is a substantive change to the terms of an underlying option. See
Note 9.
 
BASIC AND DILUTED NET INCOME PER COMMON SHARE
 
     Basic net income per common share is based on the weighted average number
of shares of common stock outstanding during each year. Diluted net income per
common share is based on the weighted average number of shares of common stock
outstanding during each year, adjusted for the effect of common stock
equivalents arising from the assumed exercise of stock options, if dilutive. See
Note 15.
 
     All per share amounts have been restated to reflect the re-incorporation
discussed at Note 1 and the mergers of IBIS Consulting, Ad Hoc and Square Earth
discussed at Note 2.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amount of the Company's cash and cash equivalents,
investments, accounts receivable, trade accounts payable and note payable
approximate fair value due to the short maturity and ready liquidity of those
instruments.

     The Company performs initial credit evaluations of its new customers and
generally does not require collateral from its customers. The Company maintains
an allowance for potential losses when identified.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
     During 1998, the Company adopted FAS 131, Disclosures About Segments of An
Enterprise and Related Information. This Statement changes the way public
companies report information about segments of their business in annual
financial statements and requires disclosure of selected segment information. It
also requires entity-wide disclosures about the products and services an entity
provides, the material countries in which it holds assets and reports revenues,
and its major customers. The Company currently operates in one operating and
geographic segment. The adoption of SFAS No. 131 does not have a material effect
on the current reporting or disclosure requirements.
 
     In June 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities. This statement requires companies to record
derivatives on the balance sheet as assets or liabilities, measured at fair
value. Gains or losses resulting from changes in the values of those derivatives
would be accounted for depending on the use of the derivative and whether it
qualifies for hedge accounting. SFAS No. 133 will be effective for the Company's
fiscal year ending December 31, 2000. The Company has no derivative or hedging
activity in any of the periods presented.
 
PRO FORMA BALANCE SHEET, NET INCOME AND EARNINGS PER SHARE (UNAUDITED)
 
     The pro forma stockholders' equity presents the effect of the automatic
conversion of the preferred stock outstanding as of December 31, 1998, as
described in Note 10, at the consummation of the public offering.
 
     As discussed in Note 2, the Company merged with IBIS Consulting and Square
Earth during 1998, and Ad Hoc during 1999, all previously Subchapter S
Corporations. Pro forma net income (loss) assuming that IBIS Consulting, Ad Hoc
and Square Earth were taxable entities during the periods presented is as

9.  STOCK OPTION PLANS
 
PROXICOM STOCK OPTION PLANS FOR EMPLOYEES AND NON-EMPLOYEES
 
     In 1996, Proxicom established a stock option plan (the "Plan") under which
eligible employees and eligible non-employees may be granted options to purchase
shares of the Company's common stock. The Plan provides for the issuance of a
maximum of 4,150,000 shares of common stock. Under the Plan, the option purchase
price for each grant is equal to the fair value of the common stock at the date
of the grant as determined by the Board of Directors. Options granted under the
plan generally vest ratably over a four-year period and expire 10 years from the
date of the grant.
 
IBIS CONSULTING
 
     In January and August 1997, IBIS Consulting granted options to two key
employees to purchase 1,759,031 shares with an exercise price of $0.219 per
share. Options for 1,496,494 shares became exercisable upon grant, with the
remaining 262,537 shares vesting over a two-year period commencing January 1,
1999. Under the terms of the option agreement, prior to the completion of an
initial public offering or sale of IBIS Consulting, IBIS Consulting was required
to repurchase and the employee was required to sell the shares or vested options
upon termination of employment, based on a pre-determined formula. After
exercise, IBIS Consulting

     NOTES TO SUPPLEMENTAL CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
retained the right and obligation to reacquire the shares based on the formula
price upon termination of the employee prior to the completion of an initial
public offering or sale of IBIS Consulting.
 
     In July 1998, one employee exercised his option to acquire 1,496,494
shares. The employee paid IBIS Consulting $330,000 to exercise the options and
received $275,000, less applicable taxes under a tax reimbursement cash bonus
arrangement.
 
     The Company recognized compensation expense in 1997 and a liability related
to both these options and the underlying cash bonus arrangement in the amount of
$220,000.
 
     In January 1997, IBIS Consulting granted options to purchase 256,065 shares
to another employee with an exercise price of $0.403 per share. These options
were subject to a vesting schedule. Employment was terminated in 1997 and the
unvested options lapsed upon termination.
 
     In January 1998, IBIS Consulting announced the grant of options under a
1998 plan and the conversion of options outstanding under the 1997 plan. In July
1998, IBIS Consulting granted such options to employees covering 82,497 shares
with an exercise price of $4.72 per share. The options are subject to an
18-month vesting schedule. Concurrent with this 1998 option grant, the remaining
1997 options of 262,537 shares were converted to the 1998 Plan. IBIS
Consulting's previous obligation to repurchase and the employees obligation to
sell the vested options upon termination of employment was eliminated.
 
     In connection with the Company's merger with IBIS Consulting, the Company
assumed all outstanding options to purchase shares of common stock of IBIS
Consulting. These options were converted into options to purchase equivalent
shares of the Company's common stock based on the merger exchange formula and
subsequently included under the Proxicom Stock Option Plan for employees and
non-employees.
 
SQUARE EARTH, INC.
 
     In connection with the Company's merger with Square Earth, the Company
assumed all outstanding options to purchase shares of common stock of Square
Earth. These options were converted into options to purchase equivalent shares
of the Company's common stock based on the merger exchange formula and
subsequently included under the Proxicom Stock Option Plan for employees and
non-employees.
 
IBIS CONSULTING STOCK-BASED AND OTHER COMPENSATION
 
     In early 1997, prior to Proxicom's investment in IBIS Consulting, IBIS
Consulting entered into an arrangement with an employee providing that
individual with 1,496,494 fully vested stock options which were subject to
certain conditions, including provisions requiring IBIS Consulting to buy back
the common stock resulting from exercise of the options and requiring the
employee to sell such shares to IBIS Consulting at a pre-determined formula upon
termination of employment. The employee exercised these options in July 1998.
Due to a change of control provision in the initial option agreement, concurrent
to the merger of IBIS Consulting and Proxicom, the repurchase requirement on the
stock and stock options was eliminated allowing the employees to freely trade
the stock.
 
     As a consequence of the above change of control provision triggered by the
merger, and the conversion of options from the 1997 plan to the 1998 plan, the
Company recorded non-cash stock-based compensation of approximately $17.0
million equal to the difference between the

     NOTES TO SUPPLEMENTAL CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
pre-determined formula price and the then fair value of the underlying stock or
stock options. As the shares were fully vested, the compensation expense was
recognized at the time of the merger.
 
     In connection with other stock option grants during the year ended December
31, 1998, the Company recognized additional stock-based compensation totaling
$219,000, and deferred stock-based compensation which is being amortized through
December 31, 1999, the 18-month vesting period of the related options. The
Company did not recognize any amortization expense during the years ended
December 31, 1996 and 1997.
 
AD HOC
 
     During 1997 and 1998, Ad Hoc granted employees the right to receive 14,435
shares and 62,226 shares of common stock, respectively, at no cost on the first
or second anniversary of their employment start date, provided that they remain
full-time employees during such period. Ad Hoc recognized non-cash compensation
expense of $44,000 and $133,000 in 1997 and 1998, respectively, related to these
rights. $19,000 and $278,000 were recorded as unearned stock compensation as of
December 31, 1997 and 1998, respectively, which will be amortized over 1999 and
2000.
 
PROXICOM STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS
 
     In February 1997, the Company established a stock option plan for
non-employee directors (the "Directors Plan") and has reserved 350,000 shares of
common stock for issuance under the provisions of this plan. Options granted
prior to December 15, 1998 generally vest over the three-year term as a
director. Options under the Directors Plan issued subsequent to December 15,
1998 are expected to be issued on a fully vested basis. Options for 175,000
shares have been granted through December 31, 1998 under the Directors Plan.
 
ACCOUNTING FOR STOCK OPTIONS ISSUED TO EMPLOYEES AND NON-EMPLOYEE DIRECTORS
 
     The Company accounts for its stock options and rights to receive stock
issued to employees and non-employee directors in accordance with APB 25 under
which compensation expense of $8,000, $264,000, and $17.3 million was recognized
for the options and rights to receive stock granted in 1996, 1997 and 1998,
respectively. The Company has provided additional pro forma disclosures as
required by SFAS No. 123, "Accounting for Stock-Based Compensation."
 
     For disclosure purposes, the fair value of each stock option and right to
receive stock is estimated on the date of grant using the Black-Scholes
option-pricing model with the following weighted average assumptions used for
stock options and rights to receive stock in 1996, 1997 and 1998: no annual
dividends, expected volatility of 0.0%, risk-free interest rate ranging from
5.1% to 6.1% and expected life of one to four years. The weighted-average fair
values of the stock options granted in 1996, 1997 and 1998 were $0.75, $3.18 and
$1.21, respectively. The weighted average fair values of the rights to receive
stock granted in 1996, 1997 and 1998 were $1.00, $3.76 and $6.39, respectively.
 
     Under the above model, the total value of stock options and rights to
receive stock granted in 1996, 1997 and 1998 were $521,000, $8.9 million and
$2.8 million, respectively, which would be amortized on a pro forma basis over
the vesting period. Had the Company determined compensation cost for these plans
in accordance with SFAS No. 123, the Company's pro forma net income (loss) would
have been approximately $1.3 million, ($796,000) and ($7.2 million)

in 1996, 1997 and 1998, respectively, and pro forma basic and diluted earnings
per common share would have been $0.09, ($0.06) and ($0.49) in 1996, 1997 and
1998, respectively.
 
ACCOUNTING FOR STOCK OPTIONS ISSUED TO NON-EMPLOYEES

10.  CONVERTIBLE PREFERRED STOCK AND WARRANTS
 
     On August 30, 1996, the Company consummated a transaction whereby: (i) the
Company repurchased from the Company's Chief Executive Officer 100,917 shares of
common stock at a price of $3.27 per share, for a total purchase price of
approximately $330,000; and, (ii) the Company issued a total of 1,629,969 shares
of Series A convertible preferred stock (the "Series A Preferred Stock") at a
price of $3.27 per share, or approximately $5.3 million. At the stockholders'
option, but in any event automatically upon an initial public offering of the
Company's common stock, each share of Series A Preferred Stock will be
convertible into one share of common stock. The Series A Preferred Stock has a
liquidation preference and is not entitled to any dividends (unless cash
dividends are declared and paid on the common stock, in which case the Series A
Preferred Stock will share on an "as if" converted basis). The holders of the
Series A Preferred Stock have registration rights and are entitled to place two
persons on the Company's Board.
 
     One investor in the Series A Preferred Stock also received warrants to
purchase 1,011,378 additional shares of Series A Preferred Stock from the
Company at a price of $7.91 per share. The warrants expire in August 2003 and
are exercisable after December 31, 1997. After December 31, 1997, the warrants
may be converted into shares of common stock at the option of the warrant
holder. The conversion formula is based on the difference between the market
value of the common stock less the warrant exercise price divided by the market
value of the common stock. The value of the warrants was not material.
 
     In February 1997, the Company consummated a transaction whereby: (i) the
Company repurchased from the Company's Chief Executive Officer 359,712 shares of
common stock at a price of $4.17 per share, for a total purchase price of
approximately $1.5 million; (ii) the Company issued a total of 359,712 shares of
Series B convertible preferred stock (the "Series B

Preferred Stock") at a price of $4.17 per share or approximately $1.5 million.
The Series B Preferred Stock has essentially the same rights and privileges as
the Series A Preferred Stock.
 
     In December 1997, the Company issued a total of 419,302 shares of Series C
convertible preferred stock (the "Series C Preferred Stock") at a price of $4.77
per share or approximately $2.0 million. The Series C Preferred Stock has
essentially the same rights and privileges as the Series A and B Preferred
Stock.
 
     In January 1998, the Company issued 407,500 shares of treasury stock in
conjunction with the conversion of 407,500 shares of Series A Preferred Stock
into common stock.
 
     In February 1999, the Company issued a total of 1,218,333 shares of Series
D convertible preferred stock (the "Series D Preferred Stock") at a price of
$6.00 per share or approximately $7.3 million. In connection with this
transaction, 758,667 shares of common stock were purchased by the investors from
selling stockholders in amounts proportionate to the investors participation in
the Series D Preferred Stock issuance. The Series D Preferred Stock has
essentially the same rights and privileges as the Series A, B and C Preferred
Stock. Because the Series D Preferred Stock was sold at a price of $6.00, it is
anticipated that such securities will be accounted for giving effect to its
beneficial conversion features. Under such accounting, the Company will record a
charge against additional paid-in capital to reflect the difference between the
conversion feature and the estimated fair value of the underlying common stock.
Although not reflected on the statement of operations, the beneficial conversion
charge will be reflected as a reduction to income and earnings per share
available for common stockholders.

     SFAS No. 128 replaces fully diluted earnings per share with diluted net
income per share which reflects the potential dilution that could occur if
securities or other contracts to issue common stock were exercised or converted
into common stock or resulted in the issuance of common stock that then shared
in the earnings of the entity.
 
16.  PENDING INVESTMENT
 
   
     In December 1998, Proxicom executed a letter of intent to make a cash
investment of approximately $360,000 in a recently formed joint venture entity
in Italy (the "Entity") created by Ericsson Telecommunicazioni SpA ("Ericsson").
Proxicom will own 19.9% of the common stock of the Entity proportionate to its
investment in relation to the total Entity capitalization. The Entity was formed
to deliver Internet professional services in Italy. It is anticipated that the
Entity will contract with Proxicom for certain consulting services, at arm's
length market rates on a time and materials basis. Also the Entity will utilize
the "Proxicom Process," Proxicom's proprietary, multi-phase methodology, which
Ericsson will transfer to the Entity for a fee. Proxicom will not participate in
the management or policy making of the business. Inasmuch as Proxicom will not
have the ability to influence significantly the entity or is operations,
Proxicom intends to account for its investment on the cost basis. Proxicom also
will have an option to buy an additional 20.0% share in the common stock of the
Entity, subject to certain conditions and restrictions. In March and April 1999,
Proxicom signed final agreements relating to this transaction.

        readiness. Of the vendors and suppliers that have responded to the
        Company's inquiries, none have informed the Company of any material Year
        2000 compliance issues and the Company has no reason to believe
        otherwise; and 

        (xxii) The Company has not taken and will not take, directly or
        indirectly, any action which is designed to or which has constituted or
        which might reasonably be expected to cause or result in stabilization

        facilitate the sale or resale of the Shares.

        statute, indenture, mortgage, deed of trust, loan agreement or other
        agreement or instrument to which such Selling Stockholder is a party or
        by which such Selling Stockholder is bound or to which any of the
        property or assets of such Selling Stockholder is subject, nor will such

        Registration Statement, any Preliminary Prospectus, the Prospectus or
        any amendment or supplement thereto are made in reliance upon and in
        conformity with written information furnished to the Company by such
        Selling Stockholder expressly for use therein, such Preliminary
        Prospectus and the Registration Statement did, and the Prospectus and
        any further amendments or supplements to the Registration Statement and

        the requirements of the Act and the rules and regulations of the
        Commission thereunder and will not contain any untrue statement of a
        material fact or omit to state any material fact required to be stated
        therein or necessary to make the statements therein not misleading;

           (vii) In order to document the Underwriters' compliance with the

           (viii) Certificates in negotiable form representing all of the Shares
        to be sold by such Selling Stockholder hereunder have been placed in
        custody under a Custody Agreement, in the form heretofore furnished to
        you (the "Custody Agreement"), duly executed and delivered by such
        Selling Stockholder to the Company, as custodian (the "Custodian"), and
        such Selling Stockholder has duly executed and delivered a Power of
        Attorney, in the form heretofore furnished to you (the "Power of
        Attorney"), appointing the persons indicated in Schedule II hereto, and
        each of them, as such Selling Stockholder's attorneys-in-fact (the

        Selling Stockholder of the Attorneys-in-Fact by the Power of Attorney,
        are to that extent irrevocable; the obligations of the Selling
        Stockholder hereunder shall not be terminated by operation of law,

        executor or trustee or the termination of such estate or trust, or in
        the case of a partnership or corporation, by the dissolution of such
        partnership or corporation, or by the occurrence of any other event; if
        any individual Selling Stockholder or any such executor or trustee
        should die or become incapacitated, or if any such estate or trust
        should be terminated, or if any such partnership or corporation should
        be dissolved, or if any other such event should occur, before the
        delivery of the Shares hereunder, certificates representing the Shares
        shall be delivered by or on behalf of the Selling Stockholder in
        accordance with the terms and conditions of this Agreement and of the
        Custody Agreements; and actions taken by the Attorneys-in-Fact pursuant
        to the Powers of Attorney shall be as valid as if such death,
        incapacity, termination, dissolution or other event had not occurred,
        regardless of whether or not the Custodian, the Attorneys-in-Fact, or
        any of them, shall have received notice of such death, incapacity,
        termination, dissolution or other event.

(a) of this Section 2, that portion of the number of Optional Shares as to which
such election shall have been exercised (to be adjusted by you so as to

Shares by a fraction the numerator of which is the maximum number of Optional
Shares which such Underwriter is entitled to purchase as set forth opposite the
name of such Underwriter in Schedule I hereto and the denominator of which is
the maximum number of Optional Shares that all of the Underwriters are entitled
to purchase hereunder.

theretofore to be performed, and the following additional conditions:

satisfactory to you, to the effect that:

                   (i) The Company was incorporated and is validly existing
               and in good standing under the laws of the State of Delaware,
               with corporate power and corporate authority under its
               Certificate of Incorporation and the Delaware Corporation Law to
               own or lease its properties and conduct its business as described
               in the Prospectus;



                                       14
<PAGE>   15

                      (ii) The Company has authorized capital stock as set forth
               under the "Actual" column of the table under the caption
               "Capitalization" in the Prospectus. All shares of capital stock
               of the Company shown as issued and outstanding under such column
               have been duly authorized and are validly issued and are fully
               paid and non-assessable. Such counsel may rely, in respect of
               matters of fact relating to consideration received for such
               stock, upon certificates of officers of the Company.) The Shares
               conform to the description of the Stock contained in the
               Prospectus under the caption "Description of Capital Stock --
               Common Stock" and when issued in accordance with the provisions
               of this Agreement, will be validly issued, fully paid and
               non-assessable;

                      (iii) The Company is in good standing and is duly
               authorized to transact business as a foreign corporation under
               the laws of each jurisdiction specified by you prior to the time
               of delivery based on where it leases properties or conducts any
               business so as to require such qualification, or is subject to no
               material liability or disability by reason of failure to be so
               qualified in any such jurisdiction (such counsel being entitled
               to rely in respect of the opinion in this clause upon opinions of
               local counsel and in respect of matters of fact upon certificates
               of officers of the Company and officials of such jurisdictions);

                      (iv) Each domestic subsidiary of the Company was
               incorporated and is validly existing as a corporation in good
               standing under the laws of its jurisdiction of incorporation;
               and all of the issued shares of capital stock of each such
               subsidiary have been duly authorized and are validly issued, are
               fully paid and non-assessable, and (except for directors'
               qualifying shares) are owned of record, directly or indirectly,
               by the Company, free and clear, to such counsel's knowledge, of
               all liens, encumbrances, equities or claims, other than the
               pledge of such shares to secure the Company's credit facility,
               (such counsel being entitled to rely in respect of the opinion
               in this clause upon opinions of local counsel and in respect of
               matters of fact upon certificates of officers of the Company or
               its subsidiaries, provided that such counsel shall state that
               they believe that both you and they are justified in relying
               upon such opinions and certificates); 

                      (v) This Agreement has been duly authorized, executed and 
               delivered by the Company;

                      (vi) The execution, delivery and performance as of the
               date of such opinion by the Company of this Agreement do not (a)
               violate the Delaware General Corporation Law, or the Certificate
               of Incorporation or Bylaws of the Company, (b) to such counsel's
               knowledge, violate any law, rule, regulation, or order applicable
               to the Company of any federal court, regulatory body,
               administrative agency or governmental body having jurisdiction
               over the Company (other than with respect to federal securities
               statutes, laws, rules or regulations) or (c) breach 


                                       15
<PAGE>   16

               or constitute a default under any agreement or contract filed as 
               an exhibit to the Registration Statement;

                      (vii) No consent, approval, authorization, order,
               registration or qualification of or with any federal or
               governmental agency or body having jurisdiction over the Company
               or any of its properties is required to be obtained or made by
               the Company in connection with the execution, delivery and
               performance by the Company of this Agreement as of the date of
               the opinion, except the registration under the Act of the Shares,
               and such consents, approvals, authorizations, registrations or
               qualifications as may be required under state securities or Blue
               Sky laws in connection with the purchase and distribution of the
               Shares by the Underwriters;

                      (viii) The information in the Prospectus under the caption
               "Description of Capital Stock", to the extent that such
               information constitutes matters of law or legal conclusions, has
               been reviewed by us, is correct in all material respects. The
               Common Stock conforms to the description thereof set forth in the
               Prospectus under the caption "Description of Capital Stock --
               Common Stock";

                      (ix) The Company is not an "investment company", as such
               term is defined in the Investment Company Act; and

                      (x) The Registration Statement and the Prospectus and any
               further amendments and supplements thereto made by the Company
               prior to such Time of Delivery (other than the financial
               statements and related schedules therein, as to which such
               counsel need express no opinion) comply as to form in all
               material respects with the requirements of the Act and the rules
               and regulations thereunder; although they do not assume any
               responsibility for the accuracy, completeness or fairness of the
               statements contained in the Registration Statement or the
               Prospectus, except for those referred to in the opinion in
               subsection (xi) of this Section 7(c), no facts have come to their
               attention which cause such counsel to believe that (a) as of its
               effective date, the Registration Statement or any further
               amendment thereto made by the Company prior to such Time of
               Delivery (other than the financial statements and related
               schedules therein, as to which such counsel need express no
               opinion) contained an untrue statement of a material fact or
               omitted to state a material fact required to be stated therein or
               necessary to make the statements therein not misleading, or that,
               as of the Time of Delivery, the Prospectus or any further
               amendment or supplement thereto made by the Company prior to such
               Time of Delivery (other than the financial statements and related
               schedules therein, as to which such counsel need express no
               opinion) contain an untrue statement of a material fact or omit
               to state a material fact necessary to make the statements
               therein, in the light of the circumstances under which they were
               made, not misleading (b) there are any legal or governmental
               proceedings pending or threatened against the Company that are
               required to be disclosed in the Registration Statement or the
               Prospectus other 


                                       16
<PAGE>   17

                than those disclosed therein, or (c) there are any contracts or
                other documents of a character required to be filed as an
                exhibit to the Registration Statement or required to be
                described in the Registration Statement or the Prospectus which
                are not filed or described as required, provided, however, that
                in making the foregoing statements, such counsel need express no
                views as to the financial statements and notes thereto, related
                schedules and other financial information and data.

            (d) Christopher Capuano, general counsel for the Company, shall have
furnished to you his written opinion (a draft of such opinion is attached as
Annex II(c) hereto), dated such Time of Delivery, in form and substance
satisfactory to you, to the effect that:

                        (i) As of the date of the opinion, none of the issue and
                sale of the Shares, the consummation of any other transaction
                contemplated in this Agreement or fulfillment of the terms of
                this Agreement violates the Certificate of Incorporation or
                By-laws of the Company or its subsidiaries or conflicts with or
                results in a breach or default in the performance or observance
                of any material obligation, agreement, covenant or condition
                contained in any agreement or contract filed as an exhibit to
                the Registration Statement;

                      (ii) To the best of such counsel's knowledge and other
               than as set forth in the Prospectus, there are no legal or
               governmental proceedings pending to which the Company or any of
               its subsidiaries is a party or of which any property of the
               Company or any of its subsidiaries is the subject which, if
               determined adversely to the Company or any of its subsidiaries,
               would individually or in the aggregate have a material adverse
               effect on the current or future consolidated financial position
               stockholders' equity or results of operations of the Company and
               its subsidiaries; and, to the best of such counsel's knowledge,
               no such proceedings are threatened or contemplated by
               governmental authorities or threatened by others; and

                  (iii) Neither the Company nor any subsidiary owns any real
               property. Any real property and buildings held under lease by the
               Company and its subsidiaries are held by them under valid,
               subsisting and enforceable leases with such exceptions as are not
               material and do not interfere with the use made and proposed to
               be made of such property and buildings by the Company and its
               subsidiaries (in giving the opinion in this clause, such counsel
               may state that no examination of record titles for the purpose of
               such opinion has been made, and that they are relying upon a
               general review of the titles of the Company and its subsidiaries,
               upon opinions of local counsel and abstracts, reports and
               policies of title companies rendered or issued at or subsequent
               to the time of acquisition of such property by the Company or its
               subsidiaries, upon opinions of counsel to the lessors of such
               property and, in respect of matters of fact, upon certificates of
               officers of the Company or its subsidiaries, provided that such
               counsel shall 



                                       17
<PAGE>   18

               state that they believe that both you and they are justified in 
               relying upon such opinions, abstracts, reports, policies and 
               certificates);

           (e) Hogan & Hartson, L.L.P., counsel for the Selling Stockholders, as
indicated in Schedule II hereto, shall have furnished to you their written
opinion with respect to the Selling Stockholder (a draft of such opinion is
attached as Annex II(d) hereto), dated such Time of Delivery, in form and
substance satisfactory to you, to the effect that:

                      (i) A Power-of-Attorney and a Custody Agreement have been
               duly executed and delivered by each of the Selling Stockholders
               and constitute valid and binding agreements of each of the
               Selling Stockholder in accordance with their terms, except (i) as
               may be limited by bankruptcy, insolvency, reorganization,
               moratorium or other laws affecting creditors' rights (including,
               without limitation, the effect of statutory and other law
               regarding fraudulent conveyances, fraudulent transfers and
               preferential transfers), (ii) as may be limited by the exercise
               of judicial discretion and the application of principles of
               equity including, without limitation, requirements of good faith,
               fair dealing, conscionability and materiality (regardless of
               whether such agreements are considered in a proceeding at equity
               or at law), and (iii) no opinion is expressed as to the
               enforceability of any indemnification provisions under the
               federal securities laws;

                      (ii) This Agreement has been duly executed and delivered
               by or on behalf of each of the Selling Stockholders; and the sale
               of the Shares to be sold by each such Selling Stockholder
               hereunder and the compliance by each such Selling Stockholder
               with all of the provisions of this Agreement, the
               Power-of-Attorney and the Custody Agreement and the consummation
               of the transactions herein and therein contemplated, to counsel's
               knowledge, do not violate (i) any applicable provisions of
               federal statutes or regulations, the contract laws of the
               Commonwealth of Virginia (but not including any statutes,
               ordinances, administrative decisions, rules or regulations of any
               political subdivision of the Commonwealth of Virginia); or (ii)
               any judgment, order or decree of any federal or Virginia
               governmental body, agency or court having jurisdiction over any
               of the Selling Stockholders;

                      (iii) To such counsel's knowledge, no consent, approval,
               authorization or order of any federal or Virginia court or
               governmental agency or body is required for the consummation of
               the transactions contemplated by this Agreement in connection
               with the Shares to be sold by the Selling Stockholders hereunder,
               except such as have been obtained under the Act and such as may
               be required under state securities or Blue Sky laws in connection
               with the purchase and distribution of such Shares by the
               Underwriters; and

                      (iv) Each of the Selling Stockholders is the registered
               owner of the Shares to be sold by each such Selling Stockholder.
               Each Selling Stockholder 



                                       18
<PAGE>   19

            acquired its Shares to be sold in the Offering free of any adverse 
            claims within the meaning of Section 8.8A-302(c) of the Commercial 
            Code of the Commonwealth of Virginia. Upon delivery to the 
            Underwriters of the Shares to be sold by the Selling Stockholders, 
            registered in the names of the Underwriters or indorsed to the 
            Underwriters or in blank by an effective indorsement pursuant to
            the  Underwriting Agreement and the Custody Agreements, or
            registration  of such Shares in the names of the Underwriters in
            the stock records  of the Company, and assuming in either case that
            the Underwriters  purchased such Shares for value, in good faith
            and without notice of  any adverse claim to such Shares within the
            meaning of Section 8.8A-302(c) of the Commercial Code of the
            Commonwealth of Virginia,  the Underwriters will have acquired such
            Shares free of adverse  claims.   

In rendering the opinion in paragraph (iv), such counsel may rely upon a
certificate of the Selling Stockholder in respect of matters of fact as to
ownership of, and liens, encumbrances, equities or claims on, the Shares sold by
the Selling Stockholder, provided that such counsel shall state that they
believe that both you and they are justified in relying upon such certificate;

        (f) On the date of the Prospectus at a time prior to the execution of
this Agreement, at 9:30 a.m., Eastern time, on the effective date of any
post-effective amendment to the Registration Statement filed subsequent to the
date of this Agreement and also at each Time of Delivery, PricewaterhouseCoopers
LLP shall have furnished to you a letter or letters, dated the respective dates
of delivery thereof, in form and substance satisfactory to you, to the effect
set forth in Annex I hereto (the executed copy of the letter delivered prior to
the execution of this Agreement is attached as Annex I(a) hereto and a draft of
the form of letter to be delivered on the effective date of any post-effective
amendment to the Registration Statement and as of each Time of Delivery is
attached as Annex I(b) hereto);

        (g)(i) Neither the Company nor any of its subsidiaries shall have
sustained since the date of the latest audited financial statements included in
the Prospectus any loss or interference with its business from fire, explosion,
flood or other calamity, whether or not covered by insurance, or from any labor
dispute or court or governmental action, order or decree, otherwise than as set
forth or contemplated in the Prospectus, and (ii) since the respective dates as
of which information is given in the Prospectus there shall not have been any
change in the capital stock or long-term debt of the Company or any of its
subsidiaries or any change, or any development involving a prospective change,
in or affecting the general affairs, management, financial position,
stockholders' equity or results of operations of the Company and its
subsidiaries, otherwise than as set forth or contemplated in the Prospectus, the
effect of which, in any such case described in clause (i) or (ii), is in the
judgment of the Representatives so material and adverse as to make it
impracticable or inadvisable to proceed with the public offering or the delivery
of the Shares being delivered at such Time of Delivery on the terms and in the
manner contemplated in the Prospectus;

        (h) On or after the date hereof there shall not have occurred any of the
following: (i) a suspension or material limitation in trading in securities
generally on the New York Stock 



                                       19
<PAGE>   20

Exchange or on the NASDAQ National Market System; (ii) a suspension or material
limitation in trading in the Company's securities on the NASDAQ National Market
Square; (iii) a general moratorium on commercial banking activities declared by
either Federal or New York State authorities; or (iv) the outbreak or escalation
of hostilities involving the United States or the declaration by the United
States of a national emergency or war, if the effect of any such event in the
judgment of the Representatives makes it impracticable or inadvisable to proceed
with the public offering or the delivery of the Shares being delivered at such
Time of Delivery on the terms and in the manner contemplated in the Prospectus;

        (i) The Shares at such Time of Delivery shall have been duly listed for
quotation on the NASDAQ National Market System;

        (j) The Company has obtained and delivered to the Underwriters executed
copies of an agreement from [all officers and directors of the Company and each
of the Selling Stockholders listed on Schedule II and certain other persons as
agreed to by the Company and you], substantially to the effect set forth in
Subsection 1(b)(iv) hereof in form and substance satisfactory to you;

        (k) The Company shall have complied with the provisions of Section 5(c)
hereof with respect to the furnishing of prospectuses on the New York Business
Day next succeeding the date of this Agreement; and

        (l) The Company and the Selling Stockholder shall have furnished to you
at such Time of Delivery certificates of officers of the Company and of the
Selling Stockholders, respectively, satisfactory to you as to the accuracy of
the representations and warranties of the Company and the Selling Stockholders,
respectively, herein at and as of such Time of Delivery, as to the performance
by the Company and the Selling Stockholders of all of their respective
obligations hereunder to be performed at or prior to such Time of Delivery, and
as to such other matters as you may reasonably request, and the Company shall
have furnished or caused to be furnished certificates as to the matters set
forth in subsections (a) and (g) of this Section.

        If any of the conditions hereinabove provided for in this Section 7
shall not have been fulfilled when and as required by this Agreement to be
fulfilled, the obligations of the Underwriters hereunder may be terminated by
you by notifying the Company and the Selling Stockholders of such termination in
writing or by telegram at or prior to the relevant Time of Delivery.

8.      INDEMNIFICATION.
        (a)    The Company agrees:

               (1) to indemnify and hold harmless each Underwriter and each
person, if any, who controls any Underwriter within the meaning of the Act,
against any losses, claims, damages or liabilities to which such Underwriter or
any such controlling person may become subject under the Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) arise out of or are based upon (i) any untrue
statement or 



                                       20
<PAGE>   21

alleged untrue statement of any material fact contained in the Registration
Statement, any Preliminary Prospectus, the Prospectus or any amendment or
supplement thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading any act or failure to act, or (iii) any alleged act or
failure to act by any Underwriter in connection with, or relating in any manner
to, the Shares or the offering contemplated hereby, and which is included as
part of or referred to in any loss, claim, damage, liability or action arising
out of or based upon matters covered by clause (i) or (ii) above; provided,
however, that the Company will not be liable in any such case to the extent that
any such loss, claim, damage or liability arises out of or is based upon an
untrue statement or alleged untrue statement, or omission or alleged omission
made in the Registration Statement, any Preliminary Prospectus, the Prospectus,
or such amendment or supplement, in reliance upon and in conformity with written
information furnished to the Company by or through the Representatives
specifically for use in the preparation thereof.

               (2) to reimburse each Underwriter and each such controlling
person upon demand for any legal or other out-of-pocket expenses reasonably
incurred by such Underwriter or such controlling person in connection with
investigating or defending any such loss, claim, damage or liability, action or
proceeding or in responding to a subpoena or governmental inquiry related to the
offering of the Shares, whether or not such Underwriter or controlling person is
a party to any action or proceeding. In the event that it is finally judicially
determined that the Underwriters were not entitled to receive payments for legal
and other expenses pursuant to this subparagraph, the Underwriters will promptly
return all sums that had been advanced pursuant hereto.

        (b) The Selling Stockholder agrees to indemnify the Underwriters and
each person, if any, who controls any Underwriter within the meaning of the Act,
against any losses, claims, damages or liabilities to which such Underwriter or
controlling person may become subject under the Act or otherwise provided,
however, that no Selling Stockholder shall be liable under this Section 8(b) for
an amount in excess of the Net Proceeds (as defined below) received by such
Selling Stockholder with respect to the Shares purchased by the Underwriters
from such Selling Stockholder. The "Net Proceeds" shall mean the proceeds
received by a Selling Stockholder for the Shares purchased by the Underwriters
from a Selling Stockholder net of the applicable underwriting discount to the
same extent as indemnity is provided by the Company pursuant to Section 8(a)
above. This indemnity obligation will be in addition to any liability which the
Company may otherwise have.

        (c) Each Underwriter severally and not jointly will indemnify and hold
harmless the Company, each of its directors, each of its officers who have
signed the Registration Statement, the Selling Stockholders, and each person, if
any, who controls the Company or Selling Stockholder within the meaning of the
Act, against any losses, claims, damages or liabilities to which the Company or
any such director, officer, Selling Shareholder or controlling person may become
subject under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) arise out of or are
based upon (i) any untrue statement or alleged untrue statement of any material
fact contained in the 



                                       21
<PAGE>   22

Registration Statement, any Preliminary Prospectus, the Prospectus or any
amendment or supplement thereto, or (ii) the omission or the alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading in the light of the circumstances under
which they were made; and will reimburse any legal or other expenses reasonably
incurred by the Company or any such director, officer, Selling Stockholder or
controlling person in connection with investigating or defending any such loss,
claim, damage, liability, action or proceeding; provided, however, that each
Underwriter will be liable in each case to the extent, but only to the extent,
that such untrue statement or alleged untrue statement or omission or alleged
omission has been made in the Registration Statement, any Preliminary
Prospectus, the Prospectus or such amendment or supplement, in reliance upon and
in conformity with written information furnished to the Company by or through
[the Representatives] specifically for use in the preparation thereof. This
indemnity agreement will be in addition to any liability which such Underwriter
may otherwise have.

        (d) In case any proceeding (including any governmental investigation)
shall be instituted involving any person in respect of which indemnity may be
sought pursuant to this Section 8, such person (the "indemnified party") shall
promptly notify the person against whom such indemnity may be sought (the
"indemnifying party") in writing. No indemnification provided for in Section
8(a), (b) or (c) shall be available to any party who shall fail to give notice
as provided in this Section 8(d) if the party to whom notice was not given was
unaware of the proceeding to which such notice would have related and was
materially prejudiced by the failure to give such notice, but the failure to
give such notice shall not relieve the indemnifying party or parties from any
liability which it or they may have to the indemnified party for contribution or
otherwise than on account of the provisions of Section 8(a), (b) or (c). In case
any such proceeding shall be brought against any indemnified party and it shall
notify the indemnifying party of the commencement thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it shall
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel satisfactory to such indemnified party and
shall pay as incurred the fees and disbursements of such counsel related to such
proceeding. In any such proceeding, any indemnified party shall have the right
to retain its own counsel at its own expense. Notwithstanding the foregoing, the
indemnifying party shall pay as incurred (or within 30 days of presentation) the
fees and expenses of the counsel retained by the indemnified party in the event
(i) the indemnifying party and the indemnified party shall have mutually agreed
to the retention of such counsel, (ii) the named parties to any such proceeding
(including any impleaded parties) include both the indemnifying party and the
indemnified party and representation of both parties by the same counsel would
be inappropriate due to actual or potential differing interests between them or
(iii) the indemnifying party shall have failed to assume the defense and employ
counsel acceptable to the indemnified party within a reasonable period of time
after notice of commencement of the action. It is understood that the
indemnifying party shall not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the reasonable fees and
expenses of more than one separate firm for all such indemnified parties. Such
firm shall be designated in writing by you in the case of parties indemnified
pursuant to Section 8(a) or (b) and by the Company and the Selling 



                                       22
<PAGE>   23

Stockholders in the case of parties indemnified pursuant to Section 8(c). The
indemnifying party shall not be liable for any settlement of any proceeding
effected without its written consent but if settled with such consent or if
there be a final judgment for the plaintiff, the indemnifying party agrees to
indemnify the indemnified party from and against any loss or liability by reason
of such settlement or judgment. In addition, the indemnifying party will not,
without the prior written consent of the indemnified party, settle or compromise
or consent to the entry of any judgment in any pending or threatened claim,
action or proceeding of which indemnification may be sought hereunder (whether
or not any indemnified party is an actual or potential party to such claim,
action or proceeding) unless such settlement, compromise or consent includes an
unconditional release of each indemnified party from all liability arising out
of such claim, action or proceeding.

        (e) If the indemnification provided for in this Section 8 is unavailable
to or insufficient to hold harmless an indemnified party under Section 8(a), (b)
or (c) above in respect of any losses, claims, damages or liabilities (or
actions or proceedings in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions or proceedings in respect thereof) in such proportion as is appropriate
to reflect the relative benefits received by the Company and the Selling
Stockholders on the one hand and the Underwriters on the other from the offering
of the Shares. If, however, the allocation provided by the immediately preceding
sentence is not permitted by applicable law then each indemnifying party shall
contribute to such amount paid or payable by such indemnified party in such
proportion as is appropriate to reflect not only such relative benefits but also
the relative fault of the Company and the Selling Stockholders on the one hand
and the Underwriters on the other in connection with the statements or omissions
which resulted in such losses, claims, damages or liabilities, (or actions or
proceedings in respect thereof), as well as any other relevant equitable
considerations. The relative benefits received by the Company and the Selling
Stockholders on the one hand and the Underwriters on the other shall be deemed
to be in the same proportion as the total net proceeds from the offering (before
deducting expenses) received by the Company and the Selling Stockholders bear to
the total underwriting discounts and commissions received by the Underwriters,
in each case as set forth in the table on the cover page of the Prospectus. The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company or the Selling Stockholders on the one hand or the Underwriters on the
other and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

        The Company, the Selling Stockholders and the Underwriters agree that it
would not be just and equitable if contributions pursuant to this Section 8(e)
were determined by pro rata allocation (even if the Underwriters were treated as
one entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to above in this Section
8(e). The amount paid or payable by an indemnified party as a result of the
losses, claims, damages or liabilities (or actions or proceedings in respect
thereof) referred 



                                       23
<PAGE>   24

to above in this Section 8(e) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this subsection (e), (i) no Underwriter shall be required to
contribute any amount in excess of the underwriting discounts and commissions
applicable to the Shares purchased by such Underwriter, and (ii) no person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation. The Underwriters' obligations in this Section
8(e) to contribute are several in proportion to their respective underwriting
obligations and not joint.

        (f) In any proceeding relating to the Registration Statement, any
Preliminary Prospectus, the Prospectus or any supplement or amendment thereto,
each party against whom contribution may be sought under this Section 8 hereby
consents to the jurisdiction of any court having jurisdiction over any other
contributing party, agrees that process issuing from such court may be served
upon him or it by any other contributing party and consents to the service of
such process and agrees that any other contributing party may join him or it as
an additional defendant in any such proceeding in which such other contributing
party is a party.

        (g) Any losses, claims, damages, liabilities or expenses for which an
indemnified party is entitled to indemnification or contribution under this
Section 8 shall be paid by the indemnifying party to the indemnified party as
such losses, claims, damages, liabilities or expenses are incurred. The
indemnity and contribution agreements contained in this Section 8 and the
representations and warranties of the Company set forth in this Agreement shall
remain operative and in full force and effect, regardless of (i) any
investigation made by or on behalf of any Underwriter or any person controlling
any Underwriter, the Company, its directors or officers or any persons
controlling the Company, (ii) acceptance of any Shares and payment therefor
hereunder, and (iii) any termination of this Agreement. A successor to any
Underwriter, or to the Company, its directors or officers, or any person
controlling the Company, shall be entitled to the benefits of the indemnity,
contribution and reimbursement agreements contained in this Section 8.

        9. (a) If any Underwriter shall default in its obligation to purchase
the Shares which it has agreed to purchase hereunder at a Time of Delivery, you
may in your discretion arrange for you or another party or other parties to
purchase such Shares on the terms contained herein. If within 36 hours after
such default by any Underwriter you do not arrange for the purchase of such
Shares, then the Company and the Selling Stockholders shall be entitled to a
further period of 36 hours within which to procure another party or other
parties satisfactory to you to purchase such Shares on such terms. In the event
that, within the respective prescribed periods, you notify the Company and the
Selling Stockholders that you have so arranged for the purchase of such Shares,
or the Company and the Selling Stockholders notify you that they have so
arranged for the purchase of such Shares, you or the Company and the Selling
Stockholders shall have the right to postpone a Time of Delivery for a period of
not more than seven days, in order to effect whatever changes may thereby be
made necessary in the Registration Statement or the Prospectus, or in any other
documents or arrangements, and the Company agrees to file 



                                       24
<PAGE>   25

promptly any amendments to the Registration Statement or the Prospectus which in
your opinion may thereby be made necessary. The term "Underwriter" as used in
this Agreement shall include any person substituted under this Section with like
effect as if such person had originally been a party to this Agreement with
respect to such Shares.

        (b) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company and
the Selling Stockholders as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased does not exceed one-eleventh of
the aggregate number of all the Shares to be purchased at such Time of Delivery,
then the Company and the Selling Stockholders shall have the right to require
each non-defaulting Underwriter to purchase the number of Shares which such
Underwriter agreed to purchase hereunder at such Time of Delivery and, in
addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the number of Shares which such Underwriter agreed to purchase
hereunder) of the Shares of such defaulting Underwriter or Underwriters for
which such arrangements have not been made; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

        (c) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company and
the Selling Stockholders as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased exceeds one-eleventh of the
aggregate number of all of the Shares to be purchased at such Time of Delivery,
or if the Company and the Selling Stockholders shall not exercise the right
described in subsection (b) above to require non-defaulting Underwriters to
purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement
(or, with respect to the Second Time of Delivery, the obligations of the
Underwriters to purchase and of the Company to sell the Optional Shares) shall
thereupon terminate, without liability on the part of any non-defaulting
Underwriter or the Company or the Selling Stockholders, except for the expenses
to be borne by the Company and the Selling Stockholders and the Underwriters as
provided in Section 6 hereof and the indemnity and contribution agreements in
Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from
liability for its default.

        10. The respective indemnities, agreements, representations, warranties
and other statements of the Company, the Selling Stockholders and the several
Underwriters, as set forth in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall remain in full force and effect,
regardless of any investigation (or any statement as to the results thereof)
made by or on behalf of any Underwriter or any controlling person of any
Underwriter, or the Company, or the Selling Stockholder, or any officer or
director or controlling person of the Company, or any controlling person of any
of the Selling Stockholders, and shall survive delivery of and payment for the
Shares.

        11. If this Agreement shall be terminated pursuant to Section 9 hereof,
neither the Company nor any Selling Stockholder shall then be under any
liability to any Underwriter except as provided in Sections 6 and 8 hereof; but,
if for any other reason any Shares are not delivered by or on behalf of the
Company and the Selling Stockholders as provided herein, the Company will
reimburse the Underwriters through you for all out-of-pocket expenses approved
in writing by 



                                       25
<PAGE>   26

you, including fees and disbursements of counsel, reasonably incurred by the
Underwriters in making preparations for the purchase, sale and delivery of the
Shares not so delivered, but the Company and the Selling Stockholders shall then
be under no further liability to any Underwriter in respect of the Shares not so
delivered except as provided in Sections 6 and 8 hereof.

        12.    TERMINATION.

               (a) This Agreement may be terminated by you by notice to the
Company and the Selling Stockholders at any time prior to the Time of Delivery
if any of the following has occurred: (i) since the respective dates as of which
information is given in the Registration Statement and the Prospectus, any
material adverse change or any development involving a prospective material
adverse change in or affecting the condition, financial or otherwise, of the
Company and its subsidiaries or the earnings, business, management, properties,
assets, rights, operations, condition (financial or otherwise) or prospects of
the Company and its subsidiaries, whether or not arising in the ordinary course
of business, (ii) any outbreak or escalation of hostilities or declaration of
war or national emergency or other national or international calamity or crisis
or change in economic or political conditions if the effect of such outbreak,
escalation, declaration, emergency, calamity, crisis or change on the financial
markets of the United States would, in your reasonable judgment, make it
impracticable or inadvisable to market the Shares or to enforce contracts for
the sale of the Shares, or (iii) suspension of trading in securities generally
on the New York Stock Exchange or the NASDAQ National Market System or
limitation on prices (other than limitations on hours or numbers of days of
trading) for securities on either of such systems, (iv) the enactment,
publication, decree or other promulgation of any statute, regulation, rule or
order of any court or other governmental authority which in your opinion
materially and adversely affects or may materially and adversely affect the
business or operations of the Company, (v) declaration of a banking moratorium
by United States or New York State authorities, (vi) the suspension of trading
of the Company's common stock by the NASDAQ Stock Market, the Commission, or any
other governmental authority or, (vii) the taking of any action by any
governmental body or agency in respect of its monetary or fiscal affairs which
in your reasonable opinion has a material adverse effect on the securities
markets in the United States; or

               (b) as provided in Sections 7 and 9 of this Agreement. 

        13. In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by BT Alex. Brown Incorporated on behalf of you as the
representatives; and in all dealings with the Selling Stockholders hereunder,
you and the Company shall be entitled to act and rely upon any statement,
request, notice or agreement on behalf of such Selling Stockholders made or
given by any or all of the Attorneys-in-Fact for such Selling Stockholder.

     All statements, requests, notices and agreements hereunder shall be in

facsimile transmission to you as the representatives in care of BT Alex. Brown

of, the Underwriters, the Company and the Selling Stockholders and, to the
extent provided in Sections 8 and 10 hereof, the officers and directors of the
Company and each person who controls the Company, any Selling Stockholder or any
Underwriter, and their respective heirs, executors, administrators, successors
and assigns, and no other person shall acquire or have any right under or by
virtue of this Agreement. No purchaser of any of the Shares from any Underwriter
shall be deemed a successor or assign by reason merely of such purchase.

     15. Time shall be of the essence of this Agreement. As used herein, the
term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

     16. This Agreement shall be governed by and construed in accordance with
the laws of the State of [Maryland].

     17. This Agreement may be executed by any one or more of the parties hereto
in any number of counterparts, each of which shall be deemed to be an original,
but all such counterparts shall together constitute one and the same instrument.

         18. The Company, the Selling Stockholders and the Underwriters
acknowledge and agree that the only information furnished or to be furnished by
any Underwriter to the Company for inclusion in any Prospectus or the
Registration Statement consists of the information set forth in the last
paragraph on the front cover page (insofar as such information relates to the
Underwriters), legends required by Item 502(d) of Regulation S-K under the Act
and the information under the caption "Underwriting" in the Prospectus.

         If the foregoing is in accordance with your understanding, please sign
and return to us one for the Company and each of the Representatives plus one
for each counsel and the Custodian, if any counterparts hereof, and upon the
acceptance hereof by you, on behalf of each of the Underwriters, this letter and
such acceptance hereof shall constitute a binding agreement among each of the
Underwriters, the Company and the Selling Stockholders. It is understood that
your acceptance of this letter on behalf of each of the Underwriters is pursuant
to the authority set forth in a form of Agreement among Underwriters, the form
of which shall be submitted to the Company and the Selling Stockholders for

                  FORM OF ANNEX I DESCRIPTION OF COMFORT LETTER
                     FOR REGISTRATION STATEMENTS ON FORM S-1

     Pursuant to Section 7(e) of the Underwriting Agreement, the accountants
shall furnish letters to the Underwriters to the effect that:

           (i) They are independent certified public accountants with respect to
        the Company and its subsidiaries within the meaning of the Act and the
        applicable published rules and regulations thereunder;

           (ii) In their opinion, the financial statements and any supplementary
        financial information and schedules (and, if applicable, financial
        forecasts and/or pro forma financial information) examined by them and
        included in the Prospectus or the Registration Statement comply as to
        form in all material respects with the applicable accounting
        requirements of the Act and the related published rules and regulations
        thereunder; and, if applicable, they have made a review in accordance
        with standards established by the American Institute of Certified Public
        Accountants of the unaudited consolidated interim financial statements,
        selected financial data, pro forma financial information, financial
        forecasts and/or condensed financial statements derived from audited
        financial statements of the Company for the periods specified in such
        letter, as indicated in their reports thereon, copies of which have been
        separately furnished to the representatives of the Underwriters (the
        "Representatives");

           (iii) They have made a review in accordance with standards
        established by the American Institute of Certified Public Accountants of
        the unaudited condensed consolidated statements of income, consolidated
        balance sheets and consolidated statements of cash flows included in the
        Prospectus as indicated in their reports thereon copies of which have
        been separately furnished to the Representatives and on the basis of
        specified procedures including inquiries of officials of the Company who
        have responsibility for financial and accounting matters regarding
        whether the unaudited condensed consolidated financial statements
        referred to in paragraph (vi)(A)(i) below comply as to form in all
        material respects with the applicable accounting requirements of the Act
        and the related published rules and regulations, nothing came to their
        attention that caused them to believe that the unaudited condensed
        consolidated financial statements do not comply as to form in all
        material respects with the applicable accounting requirements of the Act
        and the related published rules and regulations;

           (iv) The unaudited selected financial information with respect to the
        consolidated results of operations and financial position of the Company
        for the five most recent fiscal years included in the Prospectus agrees
        with the corresponding amounts (after restatements where applicable) in
        the audited consolidated financial statements for such five fiscal 

<PAGE>   32

        years which were included or incorporated by reference in the Company's 
        Annual Reports on Form 10-K for such fiscal years;

           (v) They have compared the information in the Prospectus under
        selected captions with the disclosure requirements of Regulation S-K and
        on the basis of limited procedures specified in such letter nothing came
        to their attention as a result of the foregoing procedures that caused
        them to believe that this information does not conform in all material
        respects with the disclosure requirements of Items 301, 302, 402 and
        503(d), respectively, of Regulation S-K;

           (vi) On the basis of limited procedures, not constituting an
        examination in accordance with generally accepted auditing standards,
        consisting of a reading of the unaudited financial statements and other
        information referred to below, a reading of the latest available interim
        financial statements of the Company and its subsidiaries, inspection of
        the minute books of the Company and its subsidiaries since the date of
        the latest audited financial statements included in the Prospectus,
        inquiries of officials of the Company and its subsidiaries responsible
        for financial and accounting matters and such other inquiries and
        procedures as may be specified in such letter, nothing came to their
        attention that caused them to believe that:

                (A) (i) the unaudited consolidated statements of income,
            consolidated balance sheets and consolidated statements of cash
            flows included in the Prospectus do not comply as to form in all
            material respects with the applicable accounting requirements of the
            Act and the related published rules and regulations, or (ii) any
            material modifications should be made to the unaudited condensed
            consolidated statements of income, consolidated balance sheets and
            consolidated statements of cash flows included in the Prospectus for
            them to be in conformity with generally accepted accounting
            principles;

                (B) any other unaudited income statement data and balance sheet
            items included in the Prospectus do not agree with the corresponding
            items in the unaudited consolidated financial statements from which
            such data and items were derived, and any such unaudited data and
            items were not determined on a basis substantially consistent with
            the basis for the corresponding amounts in the audited consolidated
            financial statements included in the Prospectus;

                (C) the unaudited financial statements which were not included
            in the Prospectus but from which were derived any unaudited
            condensed financial statements referred to in Clause (A) and any
            unaudited income statement data and balance sheet items included in
            the Prospectus and referred to in Clause (B) were not determined on
            a basis substantially consistent with the basis for the audited
            consolidated financial statements included in the Prospectus;


<PAGE>   33

                (D) any unaudited pro forma consolidated condensed financial
            statements included in the Prospectus do not comply as to form in
            all material respects with the applicable accounting requirements of
            the Act and the published rules and regulations thereunder or the
            pro forma adjustments have not been properly applied to the
            historical amounts in the compilation of those statements;

                (E) as of a specified date not more than five days prior to the
            date of such letter, there have been any changes in the consolidated
            capital stock (other than issuances of capital stock upon exercise
            of options and stock appreciation rights, upon earn-outs of
            performance shares and upon conversions of convertible securities,
            in each case which were outstanding on the date of the latest
            financial statements included in the Prospectus) or any increase in
            the consolidated long-term debt of the Company and its subsidiaries,
            or any decreases in consolidated net current assets or stockholders'
            equity or other items specified by the Representatives, or any
            increases in any items specified by the Representatives, in each
            case as compared with amounts shown in the latest balance sheet
            included in the Prospectus, except in each case for changes,
            increases or decreases which the Prospectus discloses have occurred
            or may occur or which are described in such letter; and

                (F) for the period from the date of the latest financial
            statements included in the Prospectus to the specified date referred
            to in Clause (E) there were any decreases in consolidated net
            revenues or operating profit or the total or per share amounts of
            consolidated net income or other items specified by the
            Representatives, or any increases in any items specified by the
            Representatives, in each case as compared with the comparable period
            of the preceding year and with any other period of corresponding
            length specified by the Representatives, except in each case for
            decreases or increases which the Prospectus discloses have occurred
            or may occur or which are described in such letter; and

           (vii) In addition to the examination referred to in their report(s)
        included in the Prospectus and the limited procedures, inspection of
        minute books, inquiries and other procedures referred to in paragraphs
        (iii) and (vi) above, they have carried out certain specified
        procedures, not constituting an examination in accordance with generally
        accepted auditing standards, with respect to certain amounts,
        percentages and financial information specified by the Representatives,
        which are derived from the general accounting records of the Company and
        its subsidiaries, which appear in the Prospectus, or in Part II of, or
        in exhibits and schedules to, the Registration Statement specified by
        the Representatives, and have compared certain of such amounts,
        percentages and financial information with the accounting records of the
        Company and its subsidiaries and have found them to be in agreement.

                       FORM OF OPINION OF GENERAL COUNSEL

       Based upon, subject to and limited by the foregoing, I am of the opinion
that:

       (i) As of the date of the opinion, none of the issue and sale of the
Shares, the consummation of any other transaction contemplated in this Agreement
or fulfillment of the terms of this Agreement violates the Certificate of
Incorporation or By-laws of the Company or its subsidiaries or conflicts with or
results in a breach or default in the performance or observance of any material
obligation, agreement, covenant or condition contained in any agreement or
contract filed as an exhibit to the Registration Statement;

       (ii) To the best of such counsel's knowledge and other than as set forth
in the Prospectus, there are no legal or governmental proceedings pending to
which the Company or any of its subsidiaries is a party or of which any property
of the Company or any of its subsidiaries is the subject which, if determined
adversely to the Company or any of its subsidiaries, would individually or in
the aggregate have a material adverse effect on the current or future
consolidated financial position stockholders' equity or results of operations of
the Company and its subsidiaries; and, to the best of such counsel's knowledge,
no such proceedings are threatened or contemplated by governmental authorities
or threatened by others; and

       (iii) Neither the Company nor any subsidiary owns any real property. Any
real property and buildings held under lease by the Company and its subsidiaries
are held by them under valid, subsisting and enforceable leases with such
exceptions as are not material and do not interfere with the use made and
proposed to be made of such property and buildings by the Company and its
subsidiaries (in giving the opinion in this clause, such counsel may state that
no examination of record titles for the purpose of such opinion has been made,
and that they are relying upon a general review of the titles of the Company and
its subsidiaries, upon opinions of local counsel and abstracts, reports and
policies of title companies rendered or issued at or subsequent to the time of
acquisition of such property by the Company or its subsidiaries, upon opinions
of counsel to the lessors of such property and, in respect of matters of fact,
upon certificates of officers of the Company or its subsidiaries, provided that
such counsel shall state that they believe that both you and they are justified
in relying upon such opinions, abstracts, reports, policies and certificates);

                                 PROXICOM, INC.

                          EMPLOYEE STOCK PURCHASE PLAN

              1.     Purpose. The purpose of the Plan is to provide employees of
                     the Company and its Designated Subsidiaries with an
                     opportunity to purchase Common Stock of the Company through
                     accumulated payroll deductions. It is the intention of the
                     Company to have the Plan qualify as an "Employee Stock
                     Purchase Plan" under Section 423 of the Internal Revenue
                     Code of 1986, as amended. The provisions of the Plan,
                     accordingly, shall be construed so as to extend and limit
                     participation in a manner consistent with the requirements
                     of that section of the Code.

              2.     Definitions.

                     1.     "Board" shall mean the Board of Directors of the
                            Company, unless the Board assigns any decisions to
                            the Compensation Committee of the Board.

                     2.     "Change in Control" shall mean:

                            i.     The acquisition by any individual, entity or

                            Purchase Price may be adjusted by the Board pursuant
                            to Section 20.

                            Stock covered by each option under the Plan which
                            have not yet been exercised, and the number of
                            shares of Common Stock that have been authorized for
                            issuance under the Plan but not yet placed under
                            option.

                     16.    "Subsidiary" shall mean a corporation, domestic or
                            foreign, of which not less than 50% of the voting
                            shares are held by the Company or a Subsidiary,
                            whether or not such corporation now exists or is
                            hereafter organized or acquired by the Company or a
                            Subsidiary.

                     17.    "Trading Day" shall mean a day on which national

              3.     Eligibility.

                     1.     Any Employee who shall be employed by the Company on

                            Enrollment Date shall be eligible to participate in 
                            the Plan.

                     2.     Any provisions of the Plan to the contrary
                            notwithstanding, no Employee shall be granted an
                            option under the Plan (i) to the extent that,
                            immediately after the grant, such Employee (or any
                            other person whose stock would be attributed to such
                            Employee pursuant to Section 424(d) of the Code)
                            would own capital stock of the Company and/or hold

                            possessing five percent (5%) or more of the total
                            combined voting power or value of all classes of the

                            or (ii) to the extent that his or her rights to
                            purchase stock under all employee stock purchase
                            plans of the Company and its subsidiaries accrues at
                            a rate which exceeds Twenty-Five Thousand Dollars
                            ($25,000) worth of stock (determined at the fair
                            market value of the shares at the time such option
                            is granted) for each calendar year in which such
                            option is outstanding at any time.

              4.     Offering Periods. The Plan shall be implemented by
                     consecutive Offering Periods with a new Offering Period
                     commencing on the first Trading Day on or after January 1
                     and July 1 each year, or on such other date as the Board
                     shall determine, and continuing thereafter until terminated
                     in accordance with Section 21 hereof; provided, however,
                     that the first Offering Period under the Plan shall
                     commence with the first Trading Day on or after the date on
                     which the Securities and Exchange Commission declares the
                     Company's Registration Statement effective and ending on
                     the last Trading Day on or before the following December
                     31. The Board shall have the power to change the duration
                     of Offering Periods (including the commencement dates
                     thereof) with respect to future offerings without
                     stockholder approval if such change is announced at least
                     five (5) days prior to the scheduled beginning of the first
                     Offering Period to be affected thereafter.

              5.     Participation.

                     1.     An eligible Employee may become a participant in the
                            Plan by completing a subscription agreement
                            authorizing payroll deductions and filing it with
                            the Company's payroll office prior to the applicable
                            Enrollment Date.

                     2.     Payroll deductions for a participant shall commence
                            on the first payroll following the Enrollment Date
                            and shall end on the last payroll in the Offering
                            Period to which such authorization is applicable,
                            unless sooner terminated by the participant as
                            provided in Section 10 hereof.

              6.     Payroll Deductions.

                     1.     At the time a participant files his or her
                            subscription agreement, he or she shall elect to
                            have payroll deductions made on each pay day during
                            the Offering Period in an amount not exceeding
                            fifteen percent (15%) of the Compensation that he or
                            she receives on each pay day during the Offering



                                       5
<PAGE>   6

                            Period.

                     2.     All payroll deductions made for a participant shall
                            be credited to his or her account under the Plan and
                            shall be withheld in whole percentages only. A
                            participant may not make any additional payments
                            into such account.

                     3.     A participant may discontinue his or her
                            participation in the Plan as provided in Section 10
                            hereof, or may decrease the rate of his or her
                            payroll deductions during the Offering Period by
                            completing or filing with the Company a new
                            subscription agreement authorizing a decrease in
                            payroll deduction rate. Once decreased or
                            discontinued, a participant may not increase the
                            rate of participation or rejoin the Plan until the
                            next Offering Period. The Board may, in its
                            discretion, limit the number of participation rate
                            changes during any Offering Period. The change in
                            rate shall be effective with the first full payroll
                            period following five (5) business days after the
                            Company's receipt of the new subscription agreement
                            unless the Company elects to process a given change
                            in participation more quickly. A participant may
                            increase the rate of his or her payroll deductions
                            effective as of the next successive Offering Period.
                            A participant's subscription agreement shall remain
                            in effect for successive Offering Periods, unless
                            terminated as provided in Section 10 hereof. 

   
                     4.     Notwithstanding the foregoing, to the extent
                            necessary to comply with Section 423(b)(8) of the
                            Code and the Plan, a participant's payroll
                            deductions may be decreased to zero percent (0%) at
                            any time during an Offering Period. Payroll
                            deductions shall recommence at the rate provided in
                            such participant's subscription agreement at the
                            beginning of the first Offering Period that is
                            scheduled to end in the following calendar year,
                            unless terminated by the participant as provided in
                            Section 10 hereof.
    

                     5.     At the time the option is exercised, in whole or in
                            part, or at the time some or all of the Company's
                            Common Stock issued under the Plan is disposed of,
                            the participant must make adequate provision for the
                            Company's federal, state, or other tax withholding
                            obligations, if any, that arise upon the exercise of
                            the option or the disposition of the Common Stock.
                            At any time, the Company may, but shall not be
                            obligated to, withhold from the participant's
                            compensation the amount necessary for the Company to
                            meet applicable withholding obligations. In
                            addition, in the event that any Employee shall sell
                            or otherwise dispose of any common stock purchased
                            under this Plan before expiration of periods
                            described in Section 422(b)(1) of the Code, such
                            Employee shall be required to notify the Company
                            within thirty (30) days of such sale or disposition.

              7.     Grant of Option. On the Enrollment Date of each Offering
                     Period, each eligible Employee participating in such
                     Offering Period shall be granted an option to purchase on
                     the Exercise Date of such Offering Period (at the
                     applicable Purchase 



                                       6
<PAGE>   7
   

                     Price) up to a number of shares of the Company's Common
                     Stock determined by dividing such Employee's payroll
                     deductions accumulated prior to such Exercise Date and
                     retained in the Participant's account as of the Exercise
                     Date by the applicable Purchase Price; provided that such
                     purchase shall be subject to the limitations set forth in
                     this Plan. Exercise of the option shall occur as provided
                     in Section 8 hereof, unless the participant has withdrawn
                     pursuant to Section 10 hereof. The Option shall expire on
                     the last day of the Offering Period.
    

              8.     Exercise of Option. Unless a participant withdraws from the
                     Plan as provided in Section 10 hereof, his or her option
                     for the purchase of shares shall be exercised automatically
                     on the Exercise Date, and the maximum number of full shares
                     subject to option shall be purchased for such participant
                     at the applicable Purchase Price with the accumulated
                     payroll deductions in his or her account. No fractional
                     shares shall be purchased; any payroll deductions
                     accumulated in a participant's account that are not
                     sufficient to purchase a full share shall be retained in
                     the participant's account for the subsequent Offering
                     Period, subject to earlier withdrawal by the participant as
                     provided in Section 10 hereof. Any other monies left over
                     in a participant's account after the Exercise Date shall be
                     returned to the participant. During a participant's
                     lifetime, a participant's option to purchase shares
                     hereunder is exercisable only by him or her. 

              9.     Custody. Shares purchased under the Plan will be held in 
                     the custody of an agent (the "Agent") appointed by the
                     Board. The Agent may hold the shares purchased under the
                     Plan in stock certificates in nominee names and may
                     commingle shares held in its custody in a single account or
                     stock certificate without identification as to individual
                     participant. A participant may, at any time following his
                     or her purchase of shares under the Plan, by written notice
                     instruct the Agent to have all or part of such shares
                     reissued in the participant's own name and have the stock
                     certificate delivered to the participant. Any dividends
                     paid on shares held by the Company for a participant's
                     account will be transmitted to the participant. The Company
                     will deliver to each participant who purchases shares of
                     Common Stock under the Plan, as promptly as practicable by
                     mail or otherwise, all notices of meetings, proxy
                     statements, proxies and other materials distributed by the
                     Company to its stockholders. Any shares of Common Stock
                     held by the Agent for an employee's account will be voted
                     in accordance with the participants's duly delivered and
                     signed proxy instructions. There will be no charge to
                     participants in connection with such notices, proxies and
                     other materials. 

              10.    Withdrawal.

   
                     1.     Consistent with the rules established by the Board,
                            a participant may withdraw all, but not less than
                            all, of the payroll deductions credited to his or
                            her account and not yet used to exercise his or her
                            option under the Plan by giving written notice to
                            the Company. All of the participant's payroll
                            deductions credited to his or her  
    



                                       7
<PAGE>   8

                            account shall be paid to such participant promptly
                            after receipt of notice of withdrawal and such
                            participant's option for the Offering Period shall
                            be automatically terminated, and no further payroll
                            deductions for the purchase of shares shall be made
                            for such Offering Period. If a participant withdraws
                            during an Offering Period, payroll deductions shall
                            not resume at the beginning of the succeeding
                            Offering Period unless the participant has delivered
                            to the Company a new subscription agreement.

                     2.     A participant's withdrawal during an Offering Period
                            shall not have any effect upon his or her
                            eligibility to participate in any similar plan that
                            may hereafter be adopted by the Company or in
                            succeeding Offering Periods which commence after the
                            termination of the Offering Period during which the
                            participant withdraws.

              11.             Termination of Employment. Upon a participant's 
                     ceasing to be an Employee for any reason, he or she shall
                     be deemed to have elected to withdraw from the Plan and the
                     payroll deductions credited to such participant's account
                     during the Offering Period but not yet used to exercise the
                     option shall be returned to such participant or, in the
                     case of his or her death, to the person or persons entitled
                     thereto under Section 15 hereof, and such participant's
                     option shall be automatically terminated.

              12.             Interest. No interest shall accrue on the payroll
                     deductions of a participant in the Plan. 
              
              13.    Stock.

   
                     1.     Subject to adjustment upon changes in capitalization
                            of the Company as provided in Section 19 hereof, the
                            maximum number of shares of the Company's Common
                            Stock that shall be made available for sale under
                            the Plan shall be one million (1,000,000) shares, or
                            such greater number of shares as is authorized. If,
                            on a given Exercise  Date, the number of shares
                            with respect to which options are to be exercised
                            exceeds the number of shares then available under
                            the Plan, the Company shall make a pro rata
                            allocation of the shares remaining available for
                            purchase in as uniform a manner as shall be
                            practicable and as it shall determine to be
                            equitable.
    

                     2.     The participant shall have no interest or voting
                            right in shares covered by his option until such
                            option has been exercised.

                     3.     Shares to be delivered to a participant under the
                            Plan shall be registered in the name of the
                            participant or in the name of the participant and
                            his or her spouse.

              14.    Administration. The Plan shall be administered by the Board
                     or a committee of members of the Board appointed by the
                     Board. The Board or its committee shall 



                                       8
<PAGE>   9

                     have full and exclusive discretionary authority to
                     construe, interpret and apply the terms of the Plan, to
                     determine eligibility and to adjudicate all disputed claims
                     filed under the Plan. Every finding, decision and
                     determination made by the Board or its committee shall, to
                     the full extent permitted by law, be final and binding upon
                     all parties. Notwithstanding anything herein, the Plan will
                     be interpreted and administered with all applicable laws
                     and regulations.

              15.    Designation of Beneficiary.

                     1.     A participant may file a written designation of a
                            beneficiary who is to receive any shares and cash,
                            if any, from the participant's account under the
                            Plan in the event of such participant's death
                            subsequent to an Exercise Date on which the option
                            is exercised but prior to delivery to such
                            participant of such shares and cash. In addition, a
                            participant may file a written designation of a
                            beneficiary who is to receive any cash from the
                            participant's account under the Plan in the event of
                            such participant's death prior to exercise of the
                            option. If a participant is married and the
                            designated beneficiary is not the spouse, spousal
                            consent shall be required for such designation to be
                            effective.

                     2.     Such designation of beneficiary may be changed by
                            the participant at any time by written notice. In
                            the event of the death of a participant and in the
                            absence of a beneficiary validly designated under
                            the Plan who is living at the time of such
                            participant's death, the Company shall deliver such
                            shares and/or cash to the executor or administrator
                            of the estate of the participant, or if no such
                            executor or administrator has been appointed (to the
                            knowledge of the Company), the Company, in its
                            discretion, may deliver such shares and/or cash to
                            the spouse or to any one or more dependents or
                            relatives of the participant, or if no spouse,
                            dependent or relative is known to the Company, then
                            to such other person as the Company may designate.

              16.    Transferability. Neither payroll deductions credited to a
                     participant's account nor any rights with regard to the
                     exercise of an option or the receipt of shares under the
                     Plan may be assigned, transferred, pledged or otherwise
                     disposed of in any way (other than by will, the laws of
                     descent and distribution or as provided in Section 15
                     hereof) by the participant. Any such attempt at assignment,
                     transfer, pledge or other disposition shall be without
                     effect, except that the Company may treat such act as an
                     election to withdraw funds during an Offering Period in
                     accordance with Section 10 hereof.

              17.    Use of Funds. All payroll deductions received or held by
                     the Company under the Plan may be used by the Company for
                     any corporate purpose, and the Company shall not be
                     obligated to segregate such payroll deductions.

              18.    Reports. Individual accounts shall be maintained for each
                     participant in the Plan. Statements of account shall be
                     given to participating Employees at least annually, 



                                       9
<PAGE>   10

                     which statements shall set forth the amounts of payroll
                     deductions, the Purchase Price, the number of shares
                     purchased and the remaining cash balance, if any.

              19.    Adjustments Upon Changes in Capitalization, Dissolution,
                     Liquidation, Merger or Asset Sale.

   
                     1.     Changes in Capitalization. Subject to any required
                            action by the stockholders of the Company, the
                            Reserves, the maximum number of shares each
                            participant may purchase per Offering Period, as
                            well as the price per share and the number of
                            shares of Common Stock covered by each option under
                            the Plan which has not yet been exercised shall be
                            proportionately adjusted for any increase or
                            decrease in the number of issued shares of Common
                            Stock resulting from a stock split, reverse stock
                            split, stock dividend, combination or
                            reclassification of the Common Stock, or any other
                            increase or decrease in the number of shares of
                            Common Stock effected without receipt of
                            consideration by the Company; provided, however,
                            that conversion of any convertible securities of
                            the Company shall not be deemed to have been
                            "effected without receipt of consideration". Such
                            adjustment shall be made by the Board, whose
                            determination in that respect shall be final,
                            binding and conclusive. Except as expressly
                            provided herein, no issuance by the Company of
                            shares of stock of any class, or securities
                            convertible into shares of stock of any class,
                            shall affect, and no adjustment by reason thereof
                            shall be made with respect to, the number or price
                            of shares of Common Stock subject to an option. 
    

                     2.     Dissolution or Liquidation. In the event of the
                            proposed dissolution or liquidation of the Company,
                            the Offering Period then in progress shall be
                            shortened by setting a new Exercise Date (the "New
                            Exercise Date") and shall terminate immediately
                            prior to the consummation of such proposed
                            dissolution or liquidation, unless provided
                            otherwise by the Board. The New Exercise Date shall
                            be before the date of the Company's proposed
                            dissolution or liquidation. The Board shall notify
                            each participant in writing, at least ten (10)
                            business days prior to the New Exercise Date, that
                            the Exercise Date for the participant's option has
                            been changed to the New Exercise Date and that the
                            participant's option shall be exercised
                            automatically on the New Exercise Date, unless prior
                            to such date the participant has withdrawn during
                            the Offering Period as provided in Section 10
                            hereof.

                     3.     Change in Control. In the event of a proposed Change
                            in Control of the Company, the Offering Period then
                            in progress shall be shortened by setting a new
                            Exercise Date (the "New Exercise Date"). The New
                            Exercise Date shall be before the date of the
                            Company's proposed Change in Control. The Board
                            shall notify each participant in writing, at least
                            ten (10) business days prior to the New Exercise
                            Date, where practicable, that 



                                       10
<PAGE>   11

                            the Exercise Date for the participant's option has
                            been changed to the New Exercise Date and that the
                            participant's option shall be exercised
                            automatically on the New Exercise Date, unless prior
                            to such date the participant has withdrawn during
                            the Offering Period as provided in Section 10
                            hereof.

              20.    Amendment or Termination.

                     1.     The Board of Directors of the Company may at any
                            time and for any reason terminate or amend the Plan.
                            Except as provided in Section 19 hereof, no such
                            termination can affect options previously granted,
                            provided that an Offering Period may be terminated
                            by the Board of Directors on any Exercise Date if
                            the Board determines that the termination of the
                            Offering Period or the Plan is in the best interests
                            of the Company and its stockholders. Except as
                            provided in Section 19 and Section 20 hereof, no
                            amendment may make any change in any option
                            theretofore granted that adversely affects the
                            rights of any participant. To the extent necessary
                            to comply with Section 423 of the Code (or any other
                            applicable law, regulation or stock exchange rule),
                            the Company shall obtain shareholder approval in
                            such a manner and to such a degree as required.

                     2.     Without stockholder consent and without regard to
                            whether any participant rights may be considered to
                            have been "adversely affected," the Board (or its
                            committee) shall be entitled to change the Offering
                            Periods, limit the frequency and/or number of
                            changes in the amount withheld during an Offering
                            Period, establish the exchange ratio applicable to
                            amounts withheld in a currency other than U.S.
                            dollars, permit payroll withholding in excess of the
                            amount designated by a participant in order to
                            adjust for delays or mistakes in the Company's
                            processing of properly completed withholding
                            elections, establish reasonable waiting and
                            adjustment periods and/or accounting and crediting
                            procedures to ensure that amounts applied toward the
                            purchase of Common Stock for each participant
                            properly correspond with amounts withheld from the
                            participant's Compensation, and establish such other
                            limitations or procedures as the Board (or its
                            committee) determines in its sole discretion to be
                            advisable and that are consistent with the Plan. 

                     3.     In the event the Board determines that the ongoing
                            operation of the Plan may result in unfavorable
                            financial accounting consequences, the Board may, in
                            its discretion and to the extent necessary or
                            desirable, modify or amend the Plan to reduce or
                            eliminate such accounting consequence, including,
                            but not limited to:

                            1.     altering the Purchase Price for any Offering
                                   Period, including an Offering Period underway
                                   at the time of the change in Purchase 


                                       11
<PAGE>   12

                                   Price;

                            2.     shortening any Offering Period so that the
                                   Offering Period ends on a new Exercise Date,
                                   including an Offering Period underway at the
                                   time of the Board action; and

                            3.     allocating shares.

                            Such modifications or amendments shall not require
                            stockholder approval or the consent of any Plan
                            participants.

              21.    Notices. All notices or other communications by a
