                                    SUMMARY

  This summary highlights information contained elsewhere in this prospectus.
You should read the entire prospectus, including "Risk Factors" and the
Financial Statements, carefully before making an investment decision.

                                  The Company

  We are a leading provider of email hosting services designed to allow a wide
range of organizations, including Internet service providers, web hosting
companies, web portals and corporations, to reduce costs and improve customer
service by outsourcing their email systems. We believe we are a leading
provider of email hosting services because our services are designed to support
growth, enhance reliability, allow access to advanced technologies and provide
greater access with high levels of security. In addition, our service is
designed so that our customers can enhance their brand recognition by
maintaining their existing "look and feel" while improving the functionality of
their email service. We intend to build on our expertise in email services to
provide additional Internet messaging services in the future. We have
approximately 250 customers. We seek to establish strategic relationships with
entities that are both commercial partners and/or equity investors or with whom
we have contractualized reseller relationships. We have strategic relationships
with ICQ, a subsidiary of America Online, E*TRADE, Network Solutions, Sprint
and US West.

  Email, one of the most popular Internet applications, has broadened from a
simple messaging tool to a widely accepted form of communication for both
personal and business use. According to Electronic Mail & Messaging Systems
("EMMS"), there were approximately 263 million electronic mailboxes worldwide
as of September 30, 1998. EMMS estimates that this number increased to 382
million electronic mailboxes worldwide as of March 31, 1999. According to the
Gartner Group, approximately 300 billion electronic mail messages were sent in
1998. In addition, the complexity of the individual messages is increasing,
allowing email to become a more functional communications tool for both
personal and business use. At the same time, we believe that customers are
increasingly expecting the same reliability from their email service that they
are accustomed to receiving from their telephone service, commonly referred to
as web-tone reliability. Due to this expectation and the expense and expertise
required to maintain a reliable email system, organizations are increasingly
seeking to outsource their email systems.

  Our services provide the following benefits to our customers:

  . reduced costs associated with acquiring and maintaining hardware and
    software and with recruiting and retaining systems engineering and
    administrative support;

  . a scalable and reliable system architecture designed to support global
    service over hundreds of millions of mailboxes across millions of domains
    with web-tone reliability;

  . access to advanced technologies based on our expertise in rapidly
    deploying new technologies, combating system failures and maintaining
    network and system security;

  . easy access by customers and end-users by designing our services on open
    Internet-based standards; and

  . control over their own brand and functionality through customized web-
    based email interfaces.

                              Recent Developments

  Since our initial public offering, we have announced several strategic
contracts that help us to expand our customer base and broaden our global
reach. We have expanded our relationship with America Online so it now includes
ICQ, AOL Latin America and AOL Enterprise, which provides us with access to one
of the largest concentrated customer bases of e-mail users on the Internet. Our
relationship with Promus provides us with access to 1,362 hotels with more than
194,000 rooms in North and South America. Furthermore, we have significantly
expanded our international customer base to include Asiamail, Avantel, British
Telecom and o.tel.o. On May 26, 1999, we acquired certain assets and customer
relationships from Fabrik Communications, Inc. for cash and common stock valued
at $20 million.

                                  RISK FACTORS

  This offering involves a high degree of risk. You should carefully consider
the risks described below and the other information in this prospectus before
deciding to invest in shares of our common stock. Our business, operating
results and financial condition could be adversely affected by any of the
following risks. 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. You should
also refer to the other information set forth in this prospectus, including our
financial statements and the related notes.

  This prospectus also contains forward-looking statements that involve risks
and uncertainties. These statements relate to our future plans, objectives,
expectations and intentions, and the assumptions underlying or relating to any
of these statements. These statements may be identified by the use of words
such as "expects," "anticipates," "intends," and "plans" and similar
expressions. Our actual results could differ materially from those discussed in
these statements. Factors that could contribute to such differences include,
but are not limited to, those discussed below and elsewhere in this prospectus.

Because we have a limited operating history, it is difficult to evaluate our
business and we may face various risks, expenses and difficulties associated
with early stage companies

  Because we have only a limited operating history upon which you can evaluate
our business and prospects, you should consider the risks, expenses and
difficulties that we may encounter when making your investment decision. These
risks include our ability to:

  . acquire businesses and technologies;

  . expand our sales and marketing activities;

  . create and maintain strategic relationships;

  . expand our customer base and retain key clients;

  . introduce new services;

  . manage growing operations;

  . compete in a highly competitive market;

  . upgrade our systems and infrastructure to handle any increases in
    messaging traffic;

  . reduce service interruptions; and

  . recruit and retain key personnel.

We expect that our operating expenses will increase as we spend resources on
building our business and that this increase may have a negative effect on our
operating results and financial condition

  We have spent heavily on technology and infrastructure development. We expect
to continue to spend substantial financial and other resources on developing
and introducing new email service offerings, and expanding our sales and
marketing organizations, strategic relationships and operating infrastructure.
We expect that our cost of revenues, sales and marketing expenses, general and
administrative expenses, operations and customer support expenses, and
depreciation and amortization expenses will continue to increase in absolute
dollars and may increase as a percent of revenues. If our revenues do not
correspondingly increase, our operating results and financial condition could
be negatively affected.

                                       6
<PAGE>

We have a history of losses, expect continuing losses and may never achieve
profitability

  We incurred net losses of approximately $1.1 million for the period from
February 19, 1997 (inception) through December 31, 1997, $11.5 million for the
year ended December 31, 1998, and $17.6 million for the three months ended
March 31, 1999. As of March 31, 1999, we had an accumulated deficit of
approximately $30.1 million. We have not achieved profitability in any period,
and we expect to continue to incur net losses for the foreseeable future.
Should we continue to incur net losses in future periods, we may not be able to
increase our number of employees or our investment in capital equipment, sales
and marketing programs, and research and development in accordance with our
present plans. Continuation of our net losses may also require us to secure
additional financing sooner than anticipated. Such financing may not be
available in sufficient amounts, or on terms acceptable to us, and may dilute
existing shareholders. We may never obtain sufficient revenues to achieve
profitability. If we do achieve profitability, we may not sustain or increase
profitability in the future. This may, in turn, cause our stock price to
decline.

Due to our limited operating history and the emerging nature of the email
services market, our future revenues are unpredictable, and our quarterly
operating results may fluctuate

  We cannot accurately forecast our revenues as a result of our limited
operating history and the emerging nature of the Internet-based email services
market. Our revenues could fall short of our expectations if we experience
delays or cancellations of even a small number of orders. We often offer
volume-based pricing, which may affect our operating margins. A number of
factors are likely to cause fluctuations in our operating results, including,
but not limited to:

  . continued growth of the Internet in general and of email usage in
    particular;

  . demand for outsourced email services;

  . our ability to attract and retain customers and maintain customer
    satisfaction;

  . our ability to upgrade, develop and maintain our systems and
    infrastructure;

  . the amount and timing of operating costs and capital expenditures
    relating to expansion of our business and infrastructure;

  . technical difficulties or system outages;

  . the announcement or introduction of new or enhanced services by our
    competitors;

  . our ability to attract and retain qualified personnel with Internet
    industry expertise, particularly sales and marketing personnel;

  . the pricing policies of our competitors;

  . failure to increase our international sales; and

  . governmental regulation surrounding the Internet and email in particular.

  In addition to the factors set forth above, our operating results will be
impacted by the extent to which we incur non-cash charges associated with
stock-based arrangements with employees and non-employees. In particular, we
expect to incur substantial non-cash charges associated with the grant of a
warrant to America Online. In addition to amortization of the initial fair
value of this warrant, which totaled $16.5 million, we expect that future
changes in the trading price of our common stock at the end of each quarter and
at the date certain milestones are achieved, will cause additional substantial
changes in the ultimate amount of such amortization. For example, we recognized
a $7.9 million non-cash charge to advertising expense during the first quarter
of 1999 in connection with the amortization of the America Online warrant.

                                       7
<PAGE>

  Due to lead times required to purchase, install and test equipment, we
typically need to purchase equipment well in advance of the receipt of any
expected revenues. Delays in obtaining this equipment could result in
unexpected revenue shortfalls. Small variations in the timing of the
recognition of specific revenues could cause significant variations in
operating results from quarter to quarter.

  Period-to-period comparisons of our operating results are not a good
indication of our future performance. It is likely that our operating results
in some quarters will be below market expectations. In this event, the price of
our common stock is likely to decline.

Acquisitions could result in dilution, operating difficulties and other harmful
consequences

  We expect that we will use a portion of the net proceeds to Critical Path of
this offering to acquire or invest in businesses, products, services and
technologies that complement or augment our service offerings and customer
base. On May 26, 1999, we acquired certain assets and customer relationships
from Fabrik Communications for cash and common stock valued at $20 million. We
are currently engaged in discussions with a number of companies regarding
strategic acquisitions or investments. Although these discussions are ongoing,
we have not signed any definitive agreements and we cannot assure you that any
of these discussions will result in actual acquisitions. To be successful, we
will need to identify suitable acquisition candidates, integrate disparate
technologies and corporate cultures and manage a geographically dispersed
company. We cannot assure you that we will be able to do this successfully.
Acquisitions could divert our attention from other business concerns and could
expose us to unforeseen liabilities. In addition, we may lose key employees
while integrating any new companies.

  We expect that we will pay for some of our acquisitions by issuing additional
common stock and this would dilute our shareholders. We may also use cash to
make acquisitions. It may be necessary for us to raise additional funds through
public or private financings. We cannot assure you that we will be able to
raise additional funds at any particular point in the future or on terms that
are favorable to us. In addition, we may be required to amortize significant
amounts of goodwill and other intangible assets in connection with future
acquisitions, which would materially increase our operating expenses.

If we fail to expand our sales and marketing activities, we may be unable to
expand our business

  Our ability to increase our revenues will depend on our ability to
successfully recruit, train and retain sales and marketing personnel. As of
March 31, 1999, we had 61 sales and marketing personnel. We plan to continue to
invest significant resources to expand our sales and marketing organizations.
Competition for additional qualified personnel is intense and we may not be
able to hire and retain personnel with relevant experience. We have recently
hired most of our sales and marketing personnel, including our Vice President
of Sales, who joined us in November 1998.

  The complexity and implementation of our Internet messaging services require
highly trained sales and marketing personnel to educate prospective customers
regarding the use and benefits of our services. Our current and prospective
customers, in turn, must be able to educate their end-users. With our
relatively brief operating history and our plans for expansion, we have
considerable need to recruit, train, and retain qualified staff. Any delays or
difficulties we encounter in these staffing efforts would impair our ability to
attract new customers and to enhance our relationships with existing customers.
This in turn would adversely impact the timing and extent of our revenues.
Because the majority of our

                                       8
<PAGE>

sales and marketing personnel have recently joined Critical Path and have
limited experience working together, our sales and marketing organizations may
not be able to compete successfully against bigger and more experienced sales
and marketing organizations of our competitors. If we do not successfully
expand our sales and marketing activities, our business could suffer and our
stock price could decline.

Unplanned system interruptions and capacity constraints could reduce our
ability to provide email services and could harm our business and our
reputation

  Our customers have in the past experienced some interruptions in our email
service. We believe that these interruptions will continue to occur from time
to time. These interruptions are due to hardware failures, unsolicited bulk
email, or "spam," attacks and operating system failures. For example, in
October 1998, our customers experienced a four-hour service interruption due to
an operating system failure. Our revenues depend on the number of end-users who
use our email services. Our business will suffer if we experience frequent or
long system interruptions that result in the unavailability or reduced
performance of our systems or networks or reduce our ability to provide email
services. We expect to experience occasional temporary capacity constraints due
to sharply increased traffic, which may cause unanticipated system disruptions,
slower response times, impaired quality and degradation in levels of customer
service. If this were to continue to happen, our business and reputation could
suffer dramatically.

  We have entered into service agreements with some of our customers that
require certain minimum performance standards, including standards regarding
the availability and response time of our email services. If we fail to meet
these standards, our customers could terminate their relationships with us and
we could be subject to contractual monetary penalties. Any unplanned
interruption of services may adversely affect our ability to attract and retain
customers.

We depend on strategic relationships and other sales channels and the loss of
any of our strategic relationships could harm our business and have an adverse
impact on our revenue

  We depend on our strategic relationships to expand our distribution channels
and to undertake joint product development and marketing efforts. Our ability
to increase revenues depends upon marketing our services through new and
existing strategic relationships. We have entered into written agreements with
ICQ, a subsidiary of America Online, E*TRADE, Network Solutions, Sprint and U S
WEST, among others. We depend on a broad acceptance of outsourced email
services on the part of potential partners and acceptance of us as the supplier
for these outsourced email services. We also depend on joint marketing and
product development through our strategic relationships to achieve market
acceptance and brand recognition. For example, through our relationship with
E*TRADE, we can conduct shared advertising campaigns and include our messaging
services in E*TRADE's international strategic relationships. Our agreements
with our strategic partners typically do not restrict them from introducing
competing services. These agreements typically are for terms of one to three
years, and automatically renew for additional one-year periods unless either
party gives prior notice of its intention to terminate the agreement. In
addition, these agreements are terminable by our partners without cause, and
some agreements are terminable by us, upon 30-120 days' notice. Most of the
agreements also provide for the partial refund of fees paid or other monetary
penalties in the event that our services fail to meet defined minimum
performance standards. Distribution partners may choose not to renew existing
arrangements on commercially acceptable terms, or at all. If we lose any of our
strategic relationships, fail to renew these agreements or relationships or
fail to develop new strategic relationships, our business will suffer. The loss
of any of our key strategic relationships would have an adverse impact on our
current and future revenue. For example, E*TRADE accounted for approximately
62% of our 1998 net revenues and TABNet, a wholly

                                       9
<PAGE>

owned subsidiary of Verio, accounted for approximately 30% of our 1998 net
revenues, excluding the value of stock purchase rights received by customers.
In the quarter ended March 31, 1999, E*TRADE accounted for approximately 48% of
our net revenues and TABNet accounted for 32% of our net revenue, excluding the
value of stock purchase rights received by customers. In addition to our
strategic relationships, we also depend on the ability of our customers to sell
and market our services to their end-users.

We have experienced rapid growth which has placed a strain on our resources and
our failure to manage our growth could cause our business to suffer

  We recently began to expand our operations rapidly and intend to continue
this expansion. The number of our employees increased from 17 on December 31,
1997 to 93 on December 31, 1998. As of March 31, 1999, we had 182 employees.
This expansion has placed, and is expected to continue to place, a significant
strain on our managerial, operational and financial resources. To manage any
further growth, we will need to improve or replace our existing operational,
customer service and financial systems, procedures and controls. Any failure by
us to properly manage these system and procedural transitions could impair our
ability to attract and service customers, and could cause us to incur higher
operating costs and delays in the execution of our business plan. We will also
need to continue the expansion of our operations and employee base. Our
management may not be able to hire, train, retain, motivate and manage required
personnel. In addition, our management may not be able to successfully
identify, manage and exploit existing and potential market opportunities. If we
cannot manage growth effectively, our business and operating results could
suffer.

We may not be able to respond to the rapid technological change of the Internet
messaging industry

  The Internet messaging industry is characterized by rapid technological
change, changes in user and customer requirements and preferences and the
emergence of new industry standards and practices that could render our
existing services, proprietary technology and systems obsolete. We must
continually improve the performance, features and reliability of our services,
particularly in response to competitive offerings. Our success depends, in
part, on our ability to enhance our existing email and messaging services and
to develop new services, functionality and technology that address the
increasingly sophisticated and varied needs of our prospective customers. If we
don't properly identify the feature preferences of prospective customers, or if
we fail to deliver email features which meet the standards of these customers,
our ability to market our service successfully and to increase our revenues
could be impaired. The development of proprietary technology and necessary
service enhancements entail significant technical and business risks and
require substantial expenditures and lead-time. We may not be able to keep pace
with the latest technological developments. We may also not be able to use new
technologies effectively or adapt our services to customer requirements or
emerging industry standards. If we cannot, for technical, legal, financial or
other reasons, adapt or respond in a cost-effective and timely manner to
changing market conditions or customer requirements, our business and operating
results would suffer.

If our system security is breached, our business and reputation could suffer

  A fundamental requirement for online communications is the secure
transmission of confidential information over public networks. Third parties
may attempt to breach our security or that of our customers. If they are
successful, they could obtain our customers' confidential information,
including our customers' profiles, passwords, financial account information,
credit card numbers or

                                       10
<PAGE>

other personal information. We may be liable to our customers for any breach in
our security and any breach could harm our reputation. We rely on encryption
technology licensed from third parties. Although we have implemented network
security measures, our servers are vulnerable to computer viruses, physical or
electronic break-ins and similar disruptions, which could lead to
interruptions, delays or loss of data. We may be required to expend significant
capital and other resources to license encryption technology and additional
technologies to protect against security breaches or to alleviate problems
caused by any breach. Our failure to prevent security breaches may have a
material adverse effect on our business and operating results.

We depend on broad market acceptance for outsourced Internet-based email
service

  The market for outsourced Internet-based email service is new and rapidly
evolving. Concerns over the security of online services and the privacy of
users may inhibit the growth of the Internet and commercial online services. We
cannot estimate the size or growth rate of the potential market for our service
offerings, and we do not know whether our service will achieve broad market
acceptance. To date, substantially all of our revenues have been derived from
sales of our email service offerings and we currently expect that our email
service offerings will account for substantially all of our revenues for the
foreseeable future. We depend on the widespread acceptance and use of
outsourcing as an effective solution for email. If the market for outsourced
email fails to grow or grows more slowly than we currently anticipate, our
business would suffer dramatically.

We expect the email services market will be very competitive and we will need
to compete successfully in this market

  We expect that the market for Internet-based email service will be intensely
competitive. In addition to competing with companies that develop and maintain
in-house solutions, we compete with email service providers, such as USA.NET,
Inc. and mail.com, and with product-based companies, such as Software.com, Inc.
and Lotus Development Corporation. We believe that competition will increase
and that companies such as Microsoft Corporation, which currently offers email
products primarily to Internet service providers who provide access to the
Internet, web hosting companies, World Wide Web sites intended to be major
starting site for users when they connect to the Internet, commonly referred to
as web portals, and corporations, may leverage their existing relationships and
capabilities to offer email services.

  We believe competition will increase as our current competitors increase the
sophistication of their offerings and as new participants enter the market.
Many of our current and potential competitors have longer operating histories,
larger customer bases, greater brand recognition and significantly greater
financial, marketing and other resources than we do and may enter into
strategic or commercial relationships with larger, more established and better-
financed companies. Further, any delays in the general market acceptance of the
email hosting concept would likely harm our competitive position. Any such
delay would allow our competitors additional time to improve their service or
product offerings, and also provide time for new competitors to develop email
service solutions and solicit prospective customers within our target markets.
Increased competition could result in pricing pressures, reduced operating
margins and loss of market share, any of which could cause our business to
suffer.

A limited number of customers account for a high percentage of our revenues and
the loss of a major customer or failure to attract new customers could harm our
business

  In 1998, E*TRADE accounted for approximately 62% of our net revenues and
TABNet accounted for approximately 30% of our net revenues, excluding the value
of stock purchase rights

                                       11
<PAGE>

received by customers. In the quarter ended March 31, 1999, E*TRADE accounted
for approximately 48% of our net revenues and TABNet accounted for
approximately 32% of our net revenues, excluding the value of stock purchase
rights received by customers. We expect that sales of our services to a limited
number of customers will continue to account for a high percentage of our
revenue for the foreseeable future. Our future success depends on our ability
to retain our current customers and attract new customers in our target
markets. The loss of a major customer or our inability to attract new customers
could have a material adverse effect on our business. Our agreements with our
customers have terms of one to three years with automatic one year renewals and
can be terminated by either party without cause upon 30-120 days' notice.

If we do not successfully address service design risks, our reputation could be
damaged and our business and operating results could suffer

  We must accurately forecast the features and functionality required by target
customers. In addition, we must design and implement service enhancements that
meet customer requirements in a timely and efficient manner. We may not
successfully determine customer requirements and we may be unable to satisfy
customer demands. Furthermore, we may not be able to design and implement a
service incorporating desired features in a timely and efficient manner. In
addition, if any new service we launch is not favorably received by customers
and end-users, our reputation could be damaged. If we fail to accurately
determine customer feature requirements or service enhancements or to market
services containing such features or enhancements in a timely and efficient
manner, our business and operating results could suffer materially.

We need to upgrade our systems and infrastructure to accommodate increases in
email traffic

  We must continue to expand and adapt our network infrastructure as the number
of users and the amount of information they wish to transmit increases, and as
their requirements change. The expansion and adaptation of our network
infrastructure will require substantial financial, operational and management
resources. Due to the limited deployment of our services to date, the ability
of our network to connect and manage a substantially larger number of customers
at high transmission speeds is unknown, and we face risks related to the
network's ability to operate with higher customer levels while maintaining
expected performance.

  As the frequency and complexity of messaging increases, we will need to make
additional investments in our infrastructure, which may be expensive. In
addition, we may not be able to accurately project the rate or timing of email
traffic increases or upgrade our systems and infrastructure to accommodate
future traffic levels. We may also not be able to achieve or maintain a
sufficiently high capacity of data transmission as customer usage increases.
Customer demand for our services could be greatly reduced if we fail to
maintain high capacity data transmission. In addition, as we upgrade our
network infrastructure to increase capacity available to our customers, we are
likely to encounter equipment or software incompatibility which may cause
delays in implementations. We may not be able to expand or adapt our network
infrastructure to meet additional demand or our customers' changing
requirements in a timely manner or at all. If we fail to do so, our business
and operating results could suffer materially.

If we do not successfully address the risks inherent in the expansion of our
international operations, our business could suffer

  We intend to continue to expand into international markets and to spend
significant financial and managerial resources to do so. If our revenues from
international operations do not exceed the

                                       12
<PAGE>

expense of establishing and maintaining these operations, our business,
financial condition and operating results will suffer. At present, we have
sales and operations subsidiaries in Germany and the United Kingdom. We have
limited experience in international operations and may not be able to compete
effectively in international markets. We face certain risks inherent in
conducting business internationally, such as:

  . unexpected changes in regulatory requirements;

  . difficulties and costs of staffing and managing international operations;

  . differing technology standards;

  . difficulties in collecting accounts receivable and longer collection
    periods;

  . political and economic instability;

  . fluctuations in currency exchange rates;

  . imposition of currency exchange controls;

  . potentially adverse tax consequences; and

  . reduced protection for intellectual property rights in certain countries.

Any of these factors could adversely affect our international operations and,
consequently, our business and operating results. Specifically, failure by us
to successfully manage our international growth could result in higher
operating costs than anticipated, or could delay or preclude altogether our
ability to generate revenues in key international markets.

Because we provide our email messaging services over the Internet, our business
could suffer if efficient transmission of data over the Internet is interrupted

  The recent growth in the use of the Internet has caused frequent
interruptions and delays in accessing the Internet and transmitting data over
the Internet. To date we have not experienced a significant adverse effect from
these interruptions. However, because we provide email messaging services over
the Internet, interruptions or delays in Internet transmissions will adversely
affect our customers' ability to send or receive their email messages. We rely
on the speed and reliability of the networks operated by third parties.
Therefore, our market depends on improvements being made to the entire Internet
infrastructure to alleviate overloading and congestion.

  We depend on telecommunications network suppliers such as MCI WorldCom and
Sprint to transmit email messages across their networks. In addition, to
deliver our services, we rely on a number of public and private peering
interconnections, which are arrangements among access providers to carry one
another's traffic. If these providers were to discontinue these arrangements,
and alternative providers did not emerge or were to increase the cost of
providing access, our ability to transmit our email traffic would be reduced.
If we were to increase our current prices to accommodate any increase in the
cost of providing access, it could negatively impact our sales. If we did not
increase our prices in response to rising access costs, our margins would be
negatively affected. Furthermore, if additional capacity is not added as
traffic increases, our ability to distribute content rapidly and reliably
through these networks will be adversely affected.

If we encounter system failure, we may not be able to provide adequate service
and our business and reputation could be damaged

  Our ability to successfully receive and send email messages and provide
acceptable levels of customer service largely depends on the efficient and
uninterrupted operation of our computer and

                                       13
<PAGE>

communications hardware and network systems. Substantially all of our computer
and communications systems are located in Palo Alto and San Francisco,
California and Laurel, Maryland. Our systems and operations are vulnerable to
damage or interruption from fire, flood, earthquake, power loss,
telecommunications failure and similar events. The occurrence of any of the
foregoing risks could subject us to contractual monetary penalties if we fail
to meet our minimum performance standards, and could have a material adverse
effect on our business and operating results and damage our reputation.

We must recruit and retain our key employees to expand our business

  Our success depends on the skills, experience and performance of our senior
management and other key personnel, many of whom have worked together for only
a short period of time. For example, our Chief Executive Officer, Chief
Financial Officer, Vice President of Sales and Vice President and Chief
Information Officer have joined us within the past twelve months. The loss of
the services of any of our senior management or other key personnel, including
our founder, David Hayden, and our President and Chief Executive Officer,
Douglas Hickey, could materially and adversely affect our business. We do not
have long-term employment agreements with any of our senior management and
other key personnel. Our success also depends on our ability to recruit, retain
and motivate other highly skilled sales and marketing, technical and managerial
personnel. Competition for these people is intense, and we may not be able to
successfully recruit, train or retain qualified personnel. In particular, we
may not be able to hire a sufficient number of qualified software developers
for our email services. If we fail to retain and recruit necessary sales and
marketing, technical and managerial personnel, our business and our ability to
develop new services and to provide acceptable levels of customer service could
suffer.

Unknown software defects could disrupt our services, which could harm our
business and reputation

  Our service offerings depend on complex software, both internally developed
and licensed from third parties. Complex software often contains defects,
particularly when first introduced or when new versions are released. Although
we conduct extensive testing, we may not discover software defects that affect
our new or current services or enhancements until after they are deployed.
Although we have not experienced any material software defects to date, it is
possible that, despite testing by us, defects may occur in the software. These
defects could cause service interruptions, which could damage our reputation or
increase our service costs, cause us to lose revenue, delay market acceptance
or divert our development resources, any of which could cause our business to
suffer.

We may need additional capital and raising additional capital may dilute
existing shareholders

  We believe that our existing capital resources, including the anticipated
proceeds of this offering, will enable us to maintain our current and planned
operations for at least the next 12 months. However, we may be required to
raise additional funds due to unforeseen circumstances. If our capital
requirements vary materially from those currently planned, we may require
additional financing sooner than anticipated. Such financing may not be
available in sufficient amounts or on terms acceptable to us and may be
dilutive to existing shareholders.

We may not be able to protect our intellectual property and proprietary rights

  We regard our copyrights, service marks, trademarks, trade secrets and
similar intellectual property as critical to our success, and rely on trademark
and copyright law, trade secret protection

                                       14
<PAGE>

and confidentiality and/or license agreements with our employees, customers and
partners to protect our proprietary rights. Despite our precautions,
unauthorized third parties may copy certain portions of our services or reverse
engineer or obtain and use information that we regard as proprietary. End-user
license provisions protecting against unauthorized use, copying, transfer and
disclosure of the licensed program may be unenforceable under the laws of
certain jurisdictions and foreign countries. The status of United States patent
protection in the software industry is not well defined and will evolve as the
U.S. Patent and Trademark Office grants additional patents. We have one patent
pending in the United States and we may seek additional patents in the future.
We do not know if our patent application or any future patent application will
be issued with the scope of the claims we seek, if at all, or whether any
patents we receive will be challenged or invalidated. In addition, the laws of
some foreign countries do not protect proprietary rights to the same extent as
do the laws of the United States. Our means of protecting our proprietary
rights in the United States or abroad may not be adequate and competitors may
independently develop similar technology.

  Third parties may infringe or misappropriate our copyrights, trademarks and
similar proprietary rights. In addition, other parties have asserted and may
assert infringement claims against us. For example, we recently received a
letter alleging that our name infringed the trade name of another company.
Although we have not received notice of any alleged patent infringement, we
cannot be certain that our products do not infringe issued patents that may
relate to our products. In addition, because patent applications in the United
States are not publicly disclosed until the patent is issued, applications may
have been filed which relate to our software products. We may be subject to
legal proceedings and claims from time to time in the ordinary course of our
business, including claims of alleged infringement of the trademarks and other
intellectual property rights of third parties. Intellectual property litigation
is expensive and time-consuming and could divert management's attention away
from running our business.

We may need to license third party technologies and we face risks in doing so

  We also intend to continue to license certain technology from third parties,
including our web server and encryption technology. The market is evolving and
we may need to license additional technologies to remain competitive. We may
not be able to license these technologies on commercially reasonable terms or
at all. In addition, we may fail to successfully integrate any licensed
technology into our services. These third-party in-licenses may expose us to
increased risks, including risks related to the integration of new technology,
the diversion of resources from the development of our own proprietary
technology, and our inability to generate revenues from new technology
sufficient to offset associated acquisition and maintenance costs. Our
inability to obtain any of these licenses could delay product and service
development until equivalent technology can be identified, licensed and
integrated. Any such delays in services could cause our business and operating
results to suffer.

Our stock price has been volatile and we expect that this volatility will
continue

  Our stock price has been highly volatile since our initial public offering on
March 29, 1999. We expect that this volatility will continue in the future due
to factors such as:

  . actual or anticipated fluctuations in our results of operations;

  . changes in or failure by us to meet securities analysts' expectations;

  . announcements of technological innovations;

  . introduction of new services by us or our competitors;

                                       15
<PAGE>

  . developments with respect to intellectual property rights;

  . conditions and trends in the Internet and other technology industries;
    and

  . general market conditions.

  In addition, the stock market has from time to time experienced significant
price and volume fluctuations that have affected the market prices for the
common stocks of technology companies, particularly Internet companies. These
broad market fluctuations may result in a material decline in the market price
of our common stock. In the past, following periods of volatility in the market
price of a particular company's securities, securities class action litigation
has often been brought against that company. We may become involved in this
type of litigation in the future. Litigation is often expensive and diverts
management's attention and resources, which could have a material adverse
effect upon our business and operating results.

Governmental regulation and legal uncertainties could impair the growth of the
Internet and decrease demand for our services or increase our cost of doing
business

  Although there are currently few laws and regulations directly applicable to
the Internet and commercial email services, a number of laws have been proposed
involving the Internet, including laws addressing user privacy, pricing,
content, copyrights, distribution, antitrust and characteristics and quality of
products and services. Further, the growth and development of the market for
online email may prompt calls for more stringent consumer protection laws that
may impose additional burdens on those companies conducting business online.
The adoption of any additional laws or regulations may impair the growth of the
Internet or commercial online services which could decrease the demand for our
services and increase our cost of doing business, or otherwise harm our
business and operating results. Moreover, the applicability to the Internet of
existing laws in various jurisdictions governing issues such as property
ownership, sales and other taxes, libel and personal privacy is uncertain and
may take years to resolve.

If we do not adequately address "Year 2000" issues, we may incur significant
costs and our business could suffer

  The Year 2000 issue is the result of computer programs and embedded hardware
systems having been developed using two digits rather than four to define the
applicable year. These computer programs or hardware that have date-sensitive
software or embedded chips may recognize a date using "00" as the year 1900
rather than the year 2000. This could result in system failures or
miscalculations causing disruptions of operations including, among other
things, a temporary inability to process transactions, send invoices or engage
in normal business activities. As a result, many companies' computer systems
may need to be upgraded or replaced in order to comply with the "Year 2000." We
are in the process of testing our internally developed software. Many of our
customers maintain their Internet operations on commercially available
operating systems, which may be impacted by Year 2000 complications. In
addition, we rely on third-party vendors for certain software and hardware
included within our services, which may not be Year 2000 compliant. Failure of
our internal computer systems or third-party equipment or software, or of
systems maintained by our suppliers, to operate properly with regard to the
year 2000 and thereafter could require us to incur significant unanticipated
expenses to remedy any problems and could cause system interruptions and loss
of data. Any of these events could harm our reputation, business and operating
results. We have not yet developed a comprehensive contingency plan to address
the issues that could result from Year 2000 complications. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--Year
2000 Issues."

                                       16
<PAGE>

We may have liability for Internet content and we may not have adequate
liability insurance

  As a provider of email services, we face potential liability for defamation,
negligence, copyright, patent or trademark infringement and other claims based
on the nature and content of the materials transmitted via email. We do not and
cannot screen all of the content generated by our users, and we could be
exposed to liability with respect to this content. Furthermore, some foreign
governments, such as Germany, have enforced laws and regulations related to
content distributed over the Internet that are more strict than those currently
in place in the United States.

  Although we carry general liability and umbrella liability insurance, our
insurance may not cover claims of these types or may not be adequate to
indemnify us for all liability that may be imposed. There is a risk that a
single claim or multiple claims, if successfully asserted against us, could
exceed the total of our coverage limits. There is also a risk that single claim
or multiple claims asserted against us may not qualify for coverage under our
insurance policies as a result of coverage exclusions that are contained within
these policies. Should either of these risks occur, capital contributed by our
shareholders may need to be used in order to settle claims. Any imposition of
liability, particularly liability that is not covered by insurance or is in
excess of insurance coverage could have a material adverse effect on our
reputation and our business and operating results, or could result in the
imposition of criminal penalties.

Future sales of our common stock may depress our stock price

  After this offering, we will have approximately 38.0 million shares of common
stock outstanding. All the shares sold in this offering will be freely
tradable. Approximately 28.1 million shares of common stock outstanding after
this offering are subject to lock-up agreements that prohibit the sale of such
shares until September 25, 1999. Immediately after the lockup period ends,
these shares will become available for sale at various times thereafter upon
the expiration, in some cases, of one-year holding periods. Sales of a
substantial number of shares of common stock in the public market after this
offering or after the expiration of the lockup and holding periods could cause
the market price of our common stock to decline.

Purchasers of our common stock will suffer immediate and substantial dilution

  The public offering price is expected to be substantially higher than the pro
forma net tangible book value per share of our common stock. Some elements of
our market value do not originate from measurable transactions. Therefore,
there is not a corresponding rise in "book" or historical cost accounting value
for our rise in market value, if any. Examples of these elements include the
perceived value associated with our strategic relationships, perceived growth
prospects of our core commercial market and our perceived competitive position
within that market. Purchasers of our common stock in this offering will
experience immediate dilution of $42.34 in the pro forma net tangible book
value per share of common stock at a public offering price of $49.375 per
share. Purchasers will also experience additional dilution upon the exercise of
outstanding stock options and warrants.

Our directors, executive officers and principal shareholders will be able to
exert significant influence over us

  After this offering, our directors, executive officers and our shareholders
who currently own over 5% of our common stock will beneficially own
approximately 61.4% of our outstanding common stock. These shareholders, if
they vote together, will be able to exercise significant influence over all
matters requiring shareholder approval, including the election of directors and
approval of

                                       17

significant corporate transactions. This concentration of ownership may also
delay or prevent a change in control of Critical Path.

Our articles of incorporation and bylaws contain provisions which could delay
or prevent a change in control

  Our articles of incorporation and bylaws contain provisions that could delay
or prevent a change in control of Critical Path. These provisions could limit
the price that investors might be willing to pay in the future for shares of
our common stock. Some of these provisions:

  . authorize the issuance of preferred stock which can be created and issued
    by the board of directors without prior shareholder approval, commonly
    referred to as "blank check" preferred stock, with rights senior to those
    of common stock;

  . prohibit shareholder action by written consent; and

  . establish advance notice requirements for submitting nominations for
    election to the board of directors and for proposing matters that can be
    acted upon by shareholders at a meeting.

  See "Description of Capital Stock" for additional discussion of these
 provisions.

If we do not use the proceeds in a manner beneficial to us, our business could
suffer

  We intend generally to use the net proceeds from this offering to acquire
businesses and technologies, expand our sales and marketing activities, open
additional data centers, expand our international operations and for general
corporate purposes, including working capital and strategic investments. We
have not yet determined the actual expected expenditures and thus cannot
estimate the amounts to be used for each specified purpose. The actual amounts
and timing of these expenditures will vary significantly depending on a number
of factors, including, but not limited to, the amount of cash generated by our
operations and the market response to the introduction of any new service
offerings. Depending on future developments and circumstances, we may use some
of the proceeds for uses other than those described above. Our management will
therefore have significant flexibility in applying the net proceeds of this
offering. If the proceeds are not used in a manner beneficial to Critical Path,
our business could suffer and our stock price could decline.

                                USE OF PROCEEDS

  We will receive approximately $141.0 million from the sale of the 3,000,000
shares offered by Critical Path, at a public offering price of $49.375 per
share, after deducting the underwriting discounts and commissions and the
estimated offering expenses payable by us. We will not receive any of the
proceeds from the sale of common stock by the selling shareholders.

  We generally intend to use the proceeds of this offering for the following:

  . acquisition of businesses and technologies;

  . expansion of our sales and marketing activities;

  . opening of additional data centers;

  . expansion of our international operations; and

  . working capital and other general corporate purposes.

  We have not yet determined the actual expected expenditures and thus cannot
estimate the amounts to be used for each purpose discussed above. The amounts
and timing of these expenditures will vary significantly depending on a number
of factors, including, but not limited to, the amount of cash generated by our
operations and the market response to the introduction of any new service
offerings.

  We expect to use a portion of the net proceeds of this offering to acquire or
invest in businesses, products, services or technologies complementary to our
current business, through mergers, acquisitions, joint ventures or otherwise.
We are currently engaged in discussions with a number of companies regarding
strategic acquisitions or investments. Although these discussions are ongoing,
we have not signed any definitive agreements and we cannot assure you that any
of these discussions will result in actual acquisitions. We intend to invest
the net proceeds of this offering in short-term, interest-bearing investment
grade securities pending the foregoing uses.

                                DIVIDEND POLICY

  We have never declared or paid dividends on our capital stock and do not
anticipate paying any dividends in the foreseeable future. We currently intend
to retain any future earnings for the expansion and operation of our business.
Furthermore, our bank line of credit agreement prohibits the payment of cash
dividends.

                                    DILUTION

  Our pro forma net tangible book value as of March 31, 1999 was $127,340,000,
or $3.63 per share of common stock. Pro forma net tangible book value per share
is determined by dividing the amount of our total tangible assets less total
liabilities by the number of shares of common stock outstanding at that date,
including the effect of (1) shares issued and net proceeds of $115.5 million
from the initial public offering and exercise of the underwriters overallotment
option and (2) the acquisition of certain assets and customer relationships
from Fabrik Communications as if the acquisition had occurred on March 31,
1999. Dilution in pro forma net tangible book value per share represents the
difference between the amount per share paid by purchasers of shares of common
stock in the offering made hereby and the net tangible book value per share of
common stock immediately after the completion of this offering. After giving
effect to the sale of the 3,000,000 shares of common stock offered by Critical
Path hereby (at a public offering price of $49.375 per share and after
deducting the underwriting discounts and commissions and our estimated offering
expenses), our pro forma as adjusted net tangible book value at March 31, 1999
would have been $268,299,000 or $7.04 per share. This represents an immediate
increase in net tangible book value of $3.41 per share to the existing
shareholders and an immediate dilution of $42.34 per share to new investors
purchasing shares in this offering. The following table illustrates this per
share dilution:

  The foregoing table includes the effect of (1) shares issued and net proceeds

underwriters overallotment option for 675,000 shares, (2) the acquisition of
certain assets and customer relationships from Fabrik Communications as if the
acquisition had occurred on March 31, 1999 and assumes no exercise of any
outstanding stock options or warrants after March 31, 1999. As of March 31,
1999, there were outstanding options to purchase an aggregate of 9,728,283
shares of common stock at a weighted average exercise price of $3.50 per share
and warrants to purchase an aggregate of 2,782,288 shares at a weighted average
purchase price of $6.00 per share. To the extent any of these options or
warrants are exercised, there will be further dilution to new investors. See

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

  The following discussion should be read in conjunction with the Consolidated
Financial Statements and Notes thereto appearing elsewhere in this prospectus.
The following discussion contains forward-looking statements. Our actual
results may differ significantly from those projected in the forward-looking
statements. Factors that might cause future results to differ materially from
those projected in the forward-looking statements include, but are not limited
to, those discussed in "Risk Factors" and elsewhere in this prospectus.

Overview

  Our company was founded in February 1997 to deliver email hosting solutions
to Internet service providers, web hosting companies, web portals and
corporations. From inception to October 1997, our operating activities related
primarily to the planning and development of our proprietary technological
solution, recruitment of personnel, raising of capital and purchase of
operating assets. We began our email hosting service in October 1997. We have
since continued to make investments to improve the quality of our service. In
December 1997, we enhanced our initial service offering, a hosting service
based on Post Office Protocol 3, with the addition of a web mail interface.
Post Office Protocol 3 is a standard protocol for receiving email commonly
referred to "POP3". In January 1999, we enhanced service with the addition of
an offering based on the Lightweight Directory Access Protocol, or LDAP, a
directory software protocol. We intend to further enhance our service offering
with the inclusion of IMAP4. IMAP4 is a new hosting service based on the
Internet Message Access Protocol, a standard protocol for accessing and storing
email from a user's server. We have approximately 250 customers.

  We derive substantially all of our revenues through the sale of email hosting
services. Our service revenues are derived primarily from contractual
relationships which provide for revenues on a per mailbox basis. These
contracts are typically one to three years in length. Agreements with some of
our customers require minimum performance standards regarding the availability
and response time of our email services. If we fail to meet these standards,
our customers could terminate their relationships with us and we could be
subject to contractual monetary penalties. Service revenues are recognized and
billed on a monthly basis as the service is performed.

  We expect to expand our operations and employee base, including our sales,
marketing, technical, operational and customer support resources. In
particular, we intend to expand our sales force to deliver our email
outsourcing services to customers in our four target markets: ISPs, web hosting
companies, web portals and corporations. We also intend to further develop new
and existing strategic relationships to expand our distribution channels and to
undertake joint product development and marketing efforts.

  We intend to continue to develop worldwide sales offices and data centers. We
currently have sales and operations subsidiaries in Germany and the United
Kingdom, and we expect to open additional data centers in the United States and
Europe during the current fiscal year.

  We expect that we will use a portion of the net proceeds to Critical Path of
this offering to acquire or invest in businesses, products, services and
technologies that complement or augment our service offerings and customer
base. On May 26, 1999, we acquired substantially all the operating assets of
the Connect Service business of Fabrik Communications. The acquisition has been

                                       23
<PAGE>

accounted for using the purchase method of accounting and accordingly, the
purchase price has been allocated to the tangible and intangible assets
acquired on the basis of their respective fair values on the acquisition date.
The total purchase price of $20.1 million consisted of $12.0 million cash and
common stock valued at $8.0 million and other acquisition related expenses of
approximately $100,000. Of the total purchase price, approximately $500,000 was
allocated to property and equipment, and the remainder was allocated to
intangible assets, including customer list ($2.1 million), assembled workforce
($400,000) and goodwill ($17.1 million). The acquired intangible assets will be
amortized over their estimated useful lives of two to three years. We are
currently engaged in discussions with a number of companies regarding strategic
acquisitions or investments. Although these discussions are ongoing, we have
not signed any definitive agreements and we cannot assure you that any of these
discussions will result in actual acquisitions.

  During 1998, we recorded aggregate unearned compensation totaling
approximately $19.9 million in connection with the certain sales of stock and
the grant of certain options to employees, directors and consultants. This
amount is being amortized over the four-year vesting period of the related
options. These options were issued to create incentives for continued
performance. Of the total unearned compensation, approximately $366,000,
$217,000, $269,000 and $1.7 million were amortized in the quarters ended March
31, June 30, September 30, and December 31, 1998. In January and March 1999, we
granted options resulting in an additional $18.1 million of unearned
compensation. Amortization of unearned compensation for the first quarter of
1999 was approximately $3.7 million. We expect aggregate per quarter
amortization related to unearned compensation of between $4.9 million and $4.0
million during 1999, between $3.2 million and $2.1 million during 2000, between
$1.7 million and $1.0 million during 2001, and between $742,000 and $331,000
during 2002.

  In January 1999, we entered into an agreement with ICQ, a subsidiary of
America Online, pursuant to which we will provide email hosting services that
will be integrated with ICQ's instant messaging service provided to ICQ's
customers. The ICQ instant messaging service is designed to allow users to
communicate in real time over the Internet. As part of the agreement, ICQ
agreed to provide sub-branded advertising for us in exchange for a warrant to
purchase 2,442,766 shares of common stock, issuable upon attainment of each of
five milestones. We believe that this agreement will have a significant current
and potential future impact on our results of operations. The following table
summarizes the shares underlying each milestone and the related exercise price:

</TABLE>

  The shares underlying the first milestone were immediately vested on the
effective date of the agreement. The shares underlying the remaining milestones
vest on the dates that ICQ completes registration of the specified number of
sub-branded ICQ mailboxes applicable to each milestone.

                                       24
<PAGE>

Using the Black-Scholes option pricing model and assuming a term of seven years
and expected volatility of 90%, the initial fair value of the warrant on the
effective date of the agreement approximated $16.5 million, which is being
amortized to advertising expense using the straight-line method over four
years. The shares underlying the second through fifth milestones will be
remeasured at each subsequent reporting date until each sub-branded ICQ mailbox
registration threshold is achieved. In the event such remeasurement results in
increases or decreases from the initial fair value, which could be substantial,
such increases or decreases will be recognized immediately, in the event the
fair value of the shares underlying the milestone has been previously
recognized, or over the remaining term. We expect to incur substantial non-cash
charges associated with the grant of the warrant to ICQ. In addition to
amortization of the initial fair value of this warrant, which totaled $16.5
million, we expect that future changes in the trading price of our common stock
at the end of each quarter and at the date certain milestones are achieved,
will cause additional substantial changes in the ultimate amount of such
amortization. For example, we recognized a $7.9 million non-cash charge to
advertising expense at the end of the first quarter of 1999 in connection with
the amortization of the ICQ warrant.

  At March 31, 1999, none of the registration milestones specified within the
ICQ warrant agreement had been achieved. Therefore, the shares underlying the
second through fifth milestones of the ICQ warrant were remeasured using the
closing price for our common stock on March 31, 1999 of $77 per share. This
remeasurement resulted in an increase to the fair value of the warrant of
$109.4 million, bringing the total fair value of the warrant to $125.9 million
as of March 31, 1999. This revised fair value will be amortized ratably over
four years, resulting in a quarterly amortization charge to advertising expense
in the amount of $7.9 million beginning in the first quarter of 1999. As noted,
this charge is subject to substantial increase or decrease in future quarters
based upon future changes in the trading price of our common stock.

  We have incurred significant losses since our inception, and as of March 31,
1999 had an accumulated deficit of approximately $30.1 million. We intend to
invest heavily to acquire new businesses and technologies, expand sales and
marketing, continue development of our network infrastructure and continue
technology developments. We expect to continue to incur substantial operating
losses for the foreseeable future.

  In view of the rapidly evolving nature of our business and our limited
operating history, we believe that period-to-period comparisons of our revenues
and operating results, including our gross profit margin and operating expenses
as a percentage of total net revenues, are not meaningful and should not be
relied upon as indications of future performance. At March 31, 1999, we had
182 employees, in comparison with 27 employees at March 31, 1998. We do not
believe that our historical growth rates for revenue, expenses, or personnel
are indicative of future results.

Results of Operations

  The following table sets forth financial data, expressed as a percentage of
net revenues, for the year ended December 31, 1998 and for the three months
ended March 31, 1998 and 1999. Data for the inception period are not presented
as Critical Path had no revenues in that period. Further, amounts from the
inception period are not comparable to those for the year ended December 31,
1998 due to the different duration of the periods and the acceleration of
Critical Path's activities and related expenses throughout 1998. We believe
that operating expenses will continue to increase in the future as we continue
to expand our operations.

 Three Months Ended March 31, 1999 Compared to Three Months Ended March 31,
1998

  Net Revenues

  Our revenues consist principally of fees we earn from providing email hosting
services. Payments for those services are based either on contractual rates per
active mailbox per month, non-refundable fixed payments, or a percentage of the
email advertising revenues earned by our customers. Revenues from contracts
specifying a contractual rate per active mailbox per month are recognized
monthly for each active mailbox covered by the respective contract. Revenues
from contracts that provide non-refundable fixed payments are not dependent
upon the active number of mailboxes, and are therefore recognized ratably over
the contract term. Revenues based upon a percentage of the email advertising
revenues generated by customers are recognized when those revenues are earned
and reported by the customer.

  During the quarter ended March 31, 1999, our revenues were $1,049,000, an
increase of $979,000 over the corresponding quarter of 1998. This increase in
revenues resulted from a substantial increase in the number of mailboxes we
hosted during the quarter ended March 31, 1999, in comparison with the
corresponding quarter of 1998. At March 31, 1999, we hosted approximately 1.4
million active mailboxes. At March 31, 1998, by comparison, we hosted
approximately 25,000 mailboxes.

  In connection with certain customer contracts executed in 1998, we granted
warrants or options to purchase common stock to such customers. The fair value
of such warrants or options, determined

                                       26
<PAGE>

using the Black-Scholes option pricing model, has been recognized ratably as a
sales discount over the terms of the respective agreements. Amortization of
this discount amounted to $106,000 during the quarter ended March 31, 1999. As
the customer contracts were executed after March 31, 1998, there was no such
amortization in the first quarter of 1998.

  In early 1998, we executed agreements with E*TRADE and TABNet, a web hosting
organization, pursuant to which we derived revenue for providing email
services. During the quarter ended March 31, 1999, E*TRADE accounted for
approximately 48% of our net revenues and TABNet accounted for 32% of our net
revenues, excluding the value of stock purchase rights received by customers.

  Cost of Net Revenues

  Cost of net revenues consists principally of costs incurred in the delivery
and support of our email services, including depreciation of capital equipment
used in our network infrastructure and personnel costs in our operations and
customer support functions. During the quarter ended March 31, 1999, these
costs were $2,360,000, or 225% of net revenues, in comparison with costs of
$82,000, or 117% of net revenues, for the corresponding quarter of 1998. We
have made significant acquisitions of equipment for our data centers over the
past nine months, and as a result our depreciation expense of networking
equipment in the first quarter of 1999 increased substantially in comparison
with the first quarter of 1998. Additionally, we have significantly increased
our staffing in operations and customer support over the past year, and
consequently compensation and other personnel costs were higher in the current
fiscal year. From January 1, 1999 to March 31, 1999, our operations and
customer support staff increased from 25 employees to 50 employees. At March
31, 1998, we had five employees on staff in operations and customer support
functions.

  Operating Expenses

  Research and Development. Our research and development expenses consist
principally of compensation for our technical staff, payments to outside
contractors, and, to a lesser extent, related overhead. We expense research and
development expenses as they are incurred. Research and development expenses
amounted to $1.4 million, or 132% of net revenues, during the first quarter of
1999, and increased substantially from the corresponding quarter of 1998 due to
our increases in personnel and use of outside contractors. From January 1, 1999
to March 31, 1999, our research and development staff increased from 27
employees to 52 employees. At March 31, 1998, we had 15 employees on staff in
research and development functions.

  Sales and Marketing. Our sales and marketing expenses consist principally of
compensation for our sales and marketing personnel, advertising, trade show and
other promotional costs, and, to a lesser extent, related overhead. Sales and
marketing expense during the quarter ended March 31, 1999, amounted to $2.0
million, or 189% of net revenue. Increases in marketing and promotional
expenses, incentive compensation payments to sales personnel, and increases in
compensation associated with additional headcount accounted for the increase to
sales and marketing expense during the first quarter of 1999 in comparison with
the corresponding quarter of 1998. From January 1, 1999 to March 31, 1999, our
sales and marketing staff increased from 30 employees to 61 employees. At March
31, 1998, we had three employees on staff in sales and marketing functions.

  General and Administrative. Our general and administrative expenses consist
principally of compensation for personnel, fees for outside professional
services, allocated occupancy costs and, to

                                       27
<PAGE>

a lesser extent, related overhead. General and administrative expenses amounted
to $1.6 million, or 148% of net revenues, during the first quarter of 1999, and
increased substantially in comparison with the corresponding quarter in 1998.
This increase was due primarily to increases in compensation associated with
additional headcount, higher fees for outside professional services, and higher
occupancy costs. From January 1, 1999 to March 31, 1999, our general and
administrative staff increased from 11 employees to 19 employees. At March 31,
1998, we had four employees on staff in general and administrative functions.

  Stock-based Expenses

  During 1998, we recorded aggregate unearned compensation in the amount of
$19.9 million in connection with the grant of certain stock options during
1998. In the first quarter of 1999, we recorded an additional $18.1 million of
unearned compensation related to the grant of stock options in the months of
January 1999 and March 1999. Amortization of such compensation amounted to
approximately $3.7 million during the first quarter of 1999. Approximately
$400,000 of this amount was allocated to cost of revenues and approximately
$3.3 million was allocated to operating expenses during the quarter.

  Additionally, we incurred stock-based expenses for warrants we granted to ICQ
and to one other strategic partner. Amortization of the fair value of these
warrants resulted in stock-based expenses of approximately $8.4 million during
the first quarter of 1999. As noted in the Overview section, quarterly
amortization associated with the ICQ warrant is subject to substantial increase
or decrease in future quarters based upon future changes in the trading price
of our common stock.

  Interest and Other Income and Interest Expense

  Interest and other income consist primarily of interest earnings on our cash
and cash equivalents. Interest and other income amounted to $351,000 during the
first quarter of 1999. We concluded private placements of equity securities in
April 1998, September 1998, and January 1999. As a result, interest income
increased significantly during the first quarter of 1999 in comparison with
previous periods due to higher cash balances available for investment. During
the first quarter of 1999, we incurred interest expense on capital lease
obligations in the amount of $64,000. In the corresponding quarter of 1998, we
incurred interest expense of $150,000, of which $119,000 related to the
amortization of stock-based charges and the remainder to interest payments on
notes payable and capital obligations.

  Income Taxes

  No provision for federal and state income taxes has been recorded as we have
incurred net operating losses from inception through March 31, 1999. As of
March 31, 1999, we had approximately $14 million of federal and state net
operating loss carryforwards available to offset future taxable income which
expire in varying amounts beginning in 2005. Under the Tax Reform Act of 1986,
the amounts of and benefits from net operating loss carryforwards may be
impaired or limited in certain circumstances. For example, the amount of net
operating losses that we may utilize in any one year would be limited in the
presence of a cumulative ownership change of more than 50% over a three year
period. Because there is significant doubt as to whether we will realize any
benefit from this deferred tax asset, we have established a full valuation
allowance as of March 31, 1999.

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

  Net Revenues

  Net revenues include charges relating to the amortization of fair value of
warrants issued to certain customers. In January 1998, we began to recognize
revenues from the sale of our email hosting services. Net revenues for 1998
were $897,000. In early 1998, we executed agreements with E*TRADE and TABNet
pursuant to which we began to derive revenue for providing email services. For
1998, E*TRADE accounted for approximately 62% and TABNet accounted for
approximately 30% of our net revenues, excluding the value of stock purchase
rights received by customers. A substantial portion of those revenues occurred
during the quarter ended December 31, 1998. Net revenues during the quarter
ended December 31, 1998 were $605,000, or 68% of net revenues for 1998.

  Costs of Net Revenues

  During 1998, our costs of net revenues were approximately $2.3 million, or
261.5% of net revenues. We made significant acquisitions of equipment for our
data centers at the beginning of the quarter ended September 30, 1998, and, as
a result, our depreciation expense increased significantly in the final two
quarters of 1998. Additionally, we significantly increased our headcount in
operations and customer support throughout the year. From January 1, 1998 to
December 31, 1998, operations and customer support personnel increased from
zero to 25.

  Operating Expenses

  Research and Development. Research and development expenses amounted to $2.1
million, or 233.8% of net revenues, during 1998, and increased substantially
each quarter throughout the year as we increased personnel and our use of
outside contractors. From January 1, 1998 to December 31, 1998, our research
and development personnel increased from 11 to 27.

  Sales and Marketing. Sales and marketing expenses amounted to $1.7 million or
188.1% of net revenue during 1998, and increased substantially in the final two
quarters of the year as we expanded our sales force and significantly increased
the promotion of our email hosting services. Increases in compensation
associated with additional headcount, incentive compensation payments, and
increases in advertising and promotional expenses accounted for the increases
to sales and marketing expense in the second half of 1998. From January 1, 1998
to December 31, 1998, our sales and marketing personnel increased from 2 to 30.

  General and Administrative. General and administrative expenses amounted to
$3.8 million, or 425.2% of net revenues, during 1998, and increased
substantially in the quarter ended December 31, 1998. Increases in compensation
associated with additional headcount, higher fees for outside professional
services, and the amortization of unearned compensation related to stock and
stock option grants accounted for this increase. From January 1, 1998 to
December 31, 1998, general and administrative personnel increased from 4 to 11.

  Stock-based Expenses

  During 1998, we recorded aggregate unearned compensation in the amount of
$19.9 million in connection with the grant of certain stock options during
1998. Related amortization totaled $2.5 million during 1998. See Notes 8 and 9
of Notes to Consolidated Financial Statements.

  Interest and Other Income and Interest Expense

  Interest and other income amounted to $375,000 during 1998. We concluded a
private placement of equity securities in September 1998. As a result, interest
income increased significantly in the final quarter of the year. To date, we
have incurred interest expense on notes payable and capital lease obligations.
For 1998, interest expense amounted to $388,000.

  Income Taxes

  No provision for federal and state income taxes was recorded as we incurred
net operating losses from inception through December 31, 1998. As of December
31, 1998, we had approximately $8.8 million of federal and state net operating
loss carryforwards available to offset future taxable income which expire in
varying amounts beginning in 2005. Under the Tax Reform Act of 1986, the
amounts of and benefits from net operating loss carryforwards may be impaired
or limited in certain circumstances. For example, the amount of net operating
losses that we may utilize in any one year would be limited in the presence of
a cumulative ownership change of more than 50% over a three year period.
Because there is significant doubt as to whether we will realize any benefit
from this deferred tax asset, we have established a full valuation allowance as
of December 31, 1998.

Quarterly Results of Operations

  The following table sets forth certain unaudited quarterly statements of
operations data for the five quarters ended March 31, 1999. This information
has been derived from Critical Path's unaudited consolidated financial
statements, which, in management's opinion, have been prepared on the same
basis as the audited consolidated financial statements, and include all
adjustments, consisting only of normal recurring adjustments, necessary for a
fair presentation of the information for the quarters presented. This
information should be read in conjunction with the audited consolidated
financial statements of Critical Path and the notes thereto included elsewhere
in this prospectus. The operating results for any quarter are not necessarily
indicative of the operating results for any future period.

expenses increased substantially during the quarter ended December 31, 1998,
due to increases in compensation associated with additional headcount, higher
fees for outside professional services, and the amortization of unearned
compensation.

Fluctuations in Quarterly Results

  We have incurred operating losses since inception, and we cannot be certain
that we will achieve profitability on a quarterly or annual basis in the
future. Critical Path believes that future operating results will be subject to
quarterly fluctuations due to a variety of factors, including, but not limited
to:

  . continued growth of the Internet and of email usage;

  . demand for outsourced email services;

  . our ability to attract and retain customers and maintain customer
    satisfaction;

  . our ability to upgrade, develop and maintain our systems and
    infrastructure;

  . the amount and timing of operating costs and capital expenditures
    relating to expansion of our business and infrastructure;

  . technical difficulties or system outages;

  . the announcement or introduction of new or enhanced services by our
    competitors;

  . our ability to attract and retain qualified personnel with Internet
    industry expertise, particularly sales and marketing personnel;

  . the pricing policies of our competitors;

  . failure to increase our international sales; and

  . governmental regulation surrounding the Internet and email in particular.

  In addition to the factors set forth above, our operating results will be
impacted by the extent to which we incur non-cash charges associated with
stock-based arrangements with the employees and non-employees. In particular,
we expect to incur substantial non-cash charges associated with the grant of a
warrant to America Online. In addition to amortization of the initial fair
value of this warrant, which totaled $16.5 million, we expect that future
changes in the trading price of our common stock at the end of each quarter and
at the date certain milestones are achieved will cause additional substantial
changes in the ultimate amount of such amortization.

  At March 31, 1999, none of the registration milestones specified within the
ICQ warrant agreement had been achieved. Therefore, the shares underlying the
second through fifth milestones of the ICQ warrant were remeasured using the
closing price for our common stock on March 31, 1999 of $77 per share. This
remeasurement resulted in an increase to the fair value of the warrant of
$109.4 million, bringing the total fair value of the warrant to $125.9 million
as of March 31, 1999. This revised fair value will be amortized ratably over
four years, resulting in a quarterly amortization charge to advertising expense
in the amount of $7.9 million beginning in the first quarter of 1999. As noted,
this charge is subject to substantial increase or decrease in future quarters
based upon future changes in the trading price of our common stock.

  Due to lead times required to purchase, install and test equipment, we
typically need to purchase equipment well in advance of the receipt of any
expected revenues. Delays in obtaining this equipment could result in
unexpected revenue shortfalls.

                                       31

Liquidity and Capital Resources

  We have funded our operations primarily from the net proceeds from the sale
of preferred stock and our initial public offering. In January 1999 we
completed the second round of the Series B Convertible Preferred Stock
financing through the issuance of approximately 3.2 million shares, including
454,544 shares issued pursuant to outstanding stock purchase rights, for gross
proceeds of $13.6 million. Also in January 1999, we sold 1,090,909 shares of
common stock for gross proceeds of $2.4 million. In April 1999, we received
approximately $115.5 million in net proceeds upon the closing of our initial
public offering of common stock.

  Our cash and cash equivalents increased by approximately $7.8 million during
the quarter ended March 31, 1999. This net change occurred as we raised
approximately $13.8 million in proceeds from the sale of equity securities, net
of issuance costs, and used $4.6 million in cash to fund operating activities.
Increased personnel costs and expanded sales and marketing programs were the
primary causes of our increased operating expenses during the first quarter of
1999. Net of depreciation, our investment in property and equipment increased
approximately $3.1 million during the quarter ended March 31, 1999.
Installation of network infrastructure equipment in our data centers, purchases
of furniture and equipment for new employees, and leasehold improvements
related to office expansions accounted for this increase.

  We have a credit agreement with a bank which provides a line of credit for
working capital advances of up to $1.0 million. There were no borrowings under
this line of credit as of March 31, 1999. Outstanding borrowings accrue
interest at a rate equal to the bank's prime rate plus 2.0%. Capital lease
obligations, including both short-term and long-term portions, increased
approximately $2.6 million, net of principal repayments, during the quarter
ended March 31, 1999 as we secured financing for a substantial share of our
additions to property and equipment. Deferred revenue decreased $500,000 during
the quarter as we recognized into revenue a payment we had previously received
from one customer as an advance for future service. Our line of credit and
capital lease obligations contain no provisions that would limit our future
borrowing ability.

  We believe that our current cash balances and proceeds from this offering
will be sufficient to meet our working capital and capital expenditure
requirements for at least the next 12 months. We anticipate that further
expansion of our operations will cause us to incur negative cash flows on a
short-term basis, and therefore require us to consume our cash and other liquid
resources to support our growth in operations. In addition, our operating and
investing activities on a long-term basis may require us to obtain additional
equity or debt financing. We expect that we will acquire or invest in
businesses, products, services and technologies that complement or augment our
service offerings and customer base. We are currently engaged in discussions
with a number of companies regarding strategic acquisitions or investments.
Although these discussions are ongoing, we have not signed any definitive
agreements and we cannot assure you that any of these discussions will result
in actual acquisitions. We expect that we will pay for some of our acquisitions
by issuing additional common stock and this could dilute our shareholders. In
addition, we may be required to amortize significant amounts of goodwill and
other intangible assets in connection with future acquisitions, which would
materially increase our operating expenses.

  Net of depreciation, our investment in property and equipment increased
approximately $3.1 million during the first quarter of 1999. Installation of
network infrastructure equipment in our data center, purchases of furniture and
equipment for new employees, and leasehold improvements related to office
expansions accounted for this increase. We expect that our investment in
property and

                                       32
<PAGE>

equipment will continue to grow as we seek to increase our capacity to provide
email hosting services.

Year 2000 Issues

  The Year 2000 issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Any computer
programs or hardware that have date-sensitive software or embedded chips may
recognize a date using "00" as the year 1900 rather than the year 2000. This
could result in system failures or miscalculations causing disruptions of
operations for any company using such computer programs or hardware, including,
among other things, a temporary inability to process transactions, send
invoices or engage in normal business activities. As a result, many companies'
computer systems may need to be upgraded or replaced in order to avoid
"Year 2000" issues.

  We are a comparatively new enterprise, and, accordingly, the software and
hardware we use to manage our business has all been purchased or developed by
us within the last 24 months. While this fact pattern does not uniformly
protect us against Year 2000 exposure, we believe we gain some mitigation from
the fact that the information technology ("IT") we use to manage our business
is not based upon "legacy" hardware and software systems. "Legacy system" is a
term often used to describe hardware and software systems which were developed
in previous decades when there was less awareness of Year 2000 issues.
Generally, hardware and software design within the current decade and the past
several years in particular has given greater consideration to Year 2000
issues. All of the software code we have internally developed to manage our
network traffic, for example, is written with four digits to define the
applicable year.

  We are in the process of testing our internal IT and non-IT systems. All of
the testing we have completed has been performed by our own personnel; to date,
we have not retained any outside service or consultants to test or review our
systems for Year 2000 compliance. Based on the testing we have performed, we
believe that this software is Year 2000 compliant. We are designing our systems
to be Year 2000 compliant and will continue to test these systems as
development of these systems progress.

  In addition to our internally developed software, we utilize software and
hardware developed by third parties both for our network and internal
information systems. To date, we have not done any testing of such third-party
software or hardware to determine Year 2000 compliance. We have, however,
obtained certifications from our key suppliers of hardware and networking
equipment for our data centers that this hardware and networking equipment are
Year 2000 compliant. Additionally, we have received assurances from the
providers of key software applications for our internal operations that their
software is Year 2000 compliant. Based upon an initial evaluation of our
broader list of software and hardware providers, we are aware that all of these
providers are in the process of reviewing and implementing their own Year 2000
compliance programs, and we will work with these providers to address the Year
2000 issue and continue to seek assurances from them that their products are
Year 2000 compliant.

  In addition, we rely on third party network infrastructure providers to gain
access to the Internet. If such providers experience business interruptions as
a result of their failure to achieve Year 2000 compliance, our ability to
provide Internet connectivity could be impaired, which could have a material
adverse effect on our business, results of operations and financial condition.

                                       33
<PAGE>

  Our customers' success in maintaining Year 2000 compliance is also
significant to our ability to generate revenues and execute our business plan.
We currently derive revenue either by charging a fixed fee per month for each
mailbox we host, or by sharing advertising revenues with our customers. In
either case, interruptions in our customers' services and on-line activities
caused by Year 2000 problems could have a material adverse effect on our
revenues to the extent that such interruptions limit or delay our customers'
ability to expand their base of email users.

  We have not incurred any significant expenses to date, and we do not
anticipate that any future costs associated with our Year 2000 remediation
efforts will be material. However, if we, our customers, our providers of
hardware and software, or our third party network providers fail to remedy any
Year 2000 issues, our service could be interrupted and we could experience a
material loss of revenues that could have a material, adverse effect on our
business, results of operations, and financial condition. We would consider
such an interruption to be the most reasonably likely unfavorable result of any
failure by us, or failure by the third parties upon whom we rely, to achieve
Year 2000 compliance. Presently, we believe we are unable to reasonably
estimate the duration and extent of any such interruption, or quantify the
effect it may have on our future revenues. We have yet to develop a
comprehensive contingency plan to address the issues which could result from
such an event. We are prepared to develop such a plan if our ongoing assessment
leads us to conclude we have significant exposure based upon the likelihood of
such an event. See "Risk Factors--We face Year 2000 risks."

Recent Accounting Pronouncements

  In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position ("SOP") No. 98-1, "Software for Internal Use," which
provides guidance on accounting for the cost of computer software developed or
obtained for internal use. SOP No. 98-1 is effective for financial statements
for fiscal years beginning after December 15, 1998. Critical Path does not
expect that the adoption of SOP No. 98-1 will have a material impact on its
consolidated financial statements.

  In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS 133"). Critical Path is required to
adopt SFAS 133 in fiscal 2000. SFAS 133 established methods of accounting for
derivative financial instruments and hedging activities related to those
instruments as well as other hedging activities. Critical Path has not yet
determined what the effect of SFAS 133 will be on its operations and financial
position.

Industry Background

  Growth of the Internet and Email

  The Internet has experienced rapid growth and has developed into a
significant tool for global communications, commerce and media, enabling
millions of people to share information and transact business electronically.
International Data Corporation ("IDC") estimates that there were over
55 million web users in the United States and over 142 million worldwide at the
end of 1998. IDC projects these numbers to increase to over 135 million web
users in the United States and over 399 million worldwide by the end of 2002.
Internet-based businesses have emerged to offer a variety of products and
services over the Internet. Additionally, many traditional businesses now use
the Internet for a growing number of applications, including advertising,
sales, customer service and training. Advances in on-line security and payment
mechanisms have also prompted more businesses and consumers to engage in
electronic commerce. IDC estimates that the number of customers buying goods
and services on the Internet will grow from 17.6 million worldwide in 1997 to
128.4 million worldwide in 2002. The growth of the Internet is the result of a
number of factors, including the extensive and growing installed base of
advanced personal computers in the home and workplace, increasingly faster and
cheaper access to the Internet, improvements in network infrastructure and an
increased awareness of the Internet among consumer and business users.
Alternative access devices, including television set-top boxes, personal
digital assistants, pagers, Internet capable telephones and wireless phones are
also contributing to the increasing use of the Internet. Further, the
development of applications for the Internet platform has helped fuel the
growth of the Internet.

                                       35
<PAGE>

  Email, one of the most popular Internet applications, has broadened from a
simple personal messaging tool to a strategic business tool. According to
Electronic Mail & Messaging Systems ("EMMS"), there were 263 million electronic
mailboxes worldwide as of September 30, 1998. EMMS estimated that this number
increased to 382 million electronic mailboxes worldwide as of March 31, 1999.
According to the Gartner Group, approximately 300 billion electronic mail
messages were sent in 1998. Email messages have increased in volume and
functionality, and this trend is expected to continue. For example, email is
expected to become a major vehicle for e-commerce transactions. Forrester
Research predicts that the typical online consumer will participate in eight to
ten commerce-related exchanges via email per week by 2001. Furthermore, the
electronic mailbox as a locating and delivering device has enabled additional
applications such as directory services, scheduling, document sharing, work-
flow and unified messaging. This increased functionality, along with the
widespread acceptance of email, positions the electronic mailbox as a platform
for other forms of electronic messaging.

  Development of Email

  Email was initially developed for isolated groups of people working on single
mainframe computers or on small networks of homogeneous computers. Early email
implementations were based on proprietary technologies, incompatible with other
systems and limited to single local area networks ("LANs"). Mail transfer
standards were subsequently developed to carry mail traffic between LANs but
did not allow for communication outside of the user's corporation or service.
While these systems were limited when compared to current email systems, they
became an increasingly important communication tool within many organizations.

  Users have migrated to open-standards mail systems, such as Lotus Notes and
Microsoft Exchange, that allow communication with any email user on the
Internet, from proprietary systems, such as Lotus cc:mail and Microsoft Mail.
Simple Mail Transport Protocol ("SMTP"), currently the most widely used mail
standard on the Internet, allows users of proprietary mail systems to
communicate over the Internet by converting messages' internal mail formats to
SMTP before transmission. In addition, new open standards are emerging to
enhance the functionality of email. For example, Post Office Protocol ("POP"),
which has been adopted by most ISPs, allows users to connect to a shared mail
server and download mail to their PC or alternative access device. In addition,
Internet Messaging Access Protocol ("IMAP"), one of the latest email standards,
allows users to access their mailboxes at the server rather than at the desktop
level. This flexibility is particularly valuable for users who access their
mail from a variety of different computers with different email clients such as
Microsoft Outlook, Eudora and HyperText Markup Language ("HTML"), more commonly
known as web-based email.

  Current Trends in Email

  As the importance of email grows, customers increasingly expect their email
service to meet the same standards of carrier-class reliability and
availability that consumers have traditionally received from their telephone
service providers. For example, email customers expect reliability from their
email service similar to the dial tone they hear when they pick up the
telephone, commonly referred to as web-tone reliability. Similarly, customers
want email access to be as ubiquitous as their telephone access by being able
to download their email from anywhere in the world, at anytime and through a
variety of devices. Just as many individuals have multiple phone numbers for
home and business use, a growing number of people have multiple email accounts.
As a result, domain names, which are the Internet identities that correlate to
unique electronic

                                       36
<PAGE>

addresses such as [email protected], are proliferating. Companies use multiple
domains to build awareness of their brands in electronic communication, and
individuals increasingly use domains to express personal identity.

  To address this growth, a wide range of businesses, including ISPs, web
hosting companies, web portals and corporations, are finding that providing
their customers or employees with email access is a necessity. ISPs, web
hosting companies and telecommunication carriers offer email to enhance their
services offerings and to maintain competitiveness with other companies in
their industry. Many web portals offer email service to increase web traffic on
their sites and strengthen their brand due to repeat traffic from users
checking for messages. In addition, corporations increasingly view email as a
means to decrease costs and increase productivity.

  Email messages have increased not only in volume but also in complexity. The
use of graphics and multimedia elements is becoming more common and requires
greater functionality on the part of the email service. As organizations and
the numbers of users grow, the ability to accommodate thousands, or millions,
of additional mailboxes in a single domain requires substantial investment in
hardware, software and personnel. Further, in the largest email
implementations, such as ISPs or web portals, the design architecture must
handle complex networking and scale issues across many domains. Web
organizations that implement and host multiple domains for customers incur
substantial additional expenses because of the complexity associated with
hosting multiple domains. There is no unified email service standard, and
online service providers must continually enhance and maintain email
applications for existing standards, as well as seek to develop new features
and functionality for emerging standards. For example, LDAP is an emerging
standard that is the foundation for adding additional applications to login and
access features of email service. Moreover, ISPs and corporations running their
own email must make substantial investments in backup systems and networking
equipment if they are to meet the growing expectation of email service with
carrier class access, availability and reliability.

  Today, most organizations are using internal hardware and software solutions
to address their email needs. Many companies attempting to manage expanding and
increasingly sophisticated email systems lack the resources and expertise to
cost-effectively implement, maintain, scale, enhance and service the hardware
and software components of an email system. Businesses often find it difficult
to implement state-of-the-art technology in their own infrastructure and
individuals with the expertise to maintain a sophisticated email system can be
scarce and costly to hire, train and retain. As a result, organizations seeking
to lower their costs and to quicken time to market with complex technologies
are increasingly looking to outsource non-core competencies to maintain
competitiveness.

Critical Path Solution

  We deliver advanced email services to ISPs, web hosting companies, web
portals and corporations, giving them the ability to provide a feature-rich
email service to their customers and employees. Our services are designed to
provide the following key benefits:

  Lower Total Cost of Ownership

  Our customers do not need to lease, buy or continually upgrade existing
hardware and software, or recruit and retain systems engineers and
administrative personnel for their email services. Our service is designed to
reduce customers' administrative burden by eliminating the cycle of purchasing,
installing, testing, debugging and deploying email systems. The software is
maintained at

                                       37

our facilities, not at customer facilities, and we employ a team of systems
administrators to monitor the service 24 hours a day, seven days a week. By
having the capability to host millions of mailboxes, we provide customers a
cost savings over in-house email solutions through economies of scale.

  Scalability; Web-Tone Reliability

  Our system's architecture and infrastructure are designed to facilitate
scalability and reliability. While existing email software solutions can scale
to support millions of users at a single domain ([email protected]), we have
designed our architecture to support our service over hundreds of millions of
mailboxes across millions of domains ([email protected], [email protected],
[email protected], etc.), allowing each customer to create email addresses at
his or her own domain. Our hardware and software infrastructure consists of
multiple servers running software in a manner that balances the use of the
servers. This infrastructure allows multiple domain hosting while reducing the
amount of required equipment and capacity. We have created a global network
strategy to provide the type of continuous service that individuals have come
to expect from their telephone service providers. We provide our customers
improved performance through our multiple peering relationships, agreements
with companies with existing peering relationships and the purchase of
additional access to telecommunication paths from national Internet access
providers. For redundancy purposes, we maintain three data centers in the
United States and plan to open additional data centers in the United States and
Europe.

  Leading-Edge Technology

  We provide our customers with access to advanced technologies. We eliminate
the need for customers and partners to maintain a core competency in email by
having experts with experience in rapidly deploying new technologies, combating
system failures due to unsolicited commercial email traffic and maintaining
network and system security. Our services include POP3, web-based email and, in
the near future, IMAP4, which enables customers to choose the option that suits
their end-users' needs. Customers rely on us to evaluate, test and implement
the leading features to maintain a leading email solution. Our technological
capabilities enable us to quickly implement competitive new technologies for
our customers and end-users, reducing their time to market for leading
technologies.

  Anytime, Anywhere Accessibility

  We have designed our services to allow easy access by customers and end-
users. Designed and built on open Internet-based standards, our services are
compatible with leading desktop software such as Microsoft Outlook and Eudora.
In addition, we have developed a web-based email interface that is compatible
with leading web browsers, including Microsoft Internet Explorer and Netscape
Navigator. Our email services are designed to allow administrators and end-
users to access their email system anywhere at any time. Our technology is
designed to support innovations in standards-based access devices, such as
hand-held computers, cellular and personal communications services ("PCS")
telephones and pagers.

  Enhanced Security

  We have created a custom firewall solution to enhance network and data center
security. Using a combination of licensed software technology, internally
developed software and sophisticated third-party hardware, we reduce the
potential for network breaches. We have network and data center

                                       38
<PAGE>

surveillance 24 hours a day, seven days a week to identify and curtail
potential security breaches. We are not aware of any security breaches to our
network.

  Branding; Customer Control

  Our messaging service solution enables our customers to maintain control over
their own brand and desired functionality. Our fully customized web-based
"brandable" email interfaces include customer logos and preserve the existing
"look and feel" of the customers' brands. Our web-based Mail Administration
Center is designed to give customers control via a secure Account Provisioning
Protocol, a software interface into our platform which allows customers to
integrate their existing functionality with our mail system. This enables
customers to add and delete accounts and functionality either at the domain
level, or at the individual end-user level.

Strategy

  Our objective is to be the premier provider of comprehensive, advanced
Internet messaging services. We plan to attain this goal by pursuing the
following key strategies:

  Extend Technology Leadership in Messaging Applications

  We intend to capitalize on our expertise in email services to deliver
industry-leading functionality to other types of electronic messaging. Building
upon our Internet-based email architecture, we plan to deliver industry-leading
functionality, including global and local directories and other capabilities,
and to deliver new applications that will extend the core functionality of
email and integrate smoothly with existing back office applications. Our
services development team regularly meets with customers and participates in
research projects with leading industry groups and analysts to anticipate
future customer needs. We also participate in open standards organizations and
Internet technology leadership groups, such as IETF (Internet Engineering Task
Force), the North American Network Operators Group and the Coalition Against
Unsolicited Commercial Email, a spam control organization.

  Acquire New Businesses and Technologies

  We evaluate acquisition opportunities on an ongoing basis and, at the present
time, are engaged in discussions with respect to possible acquisitions of
businesses or technologies. We will continue to seek acquisitions that will
complement our current and planned business activities. We have a dual strategy
in pursuing acquisitions. First, we plan to focus on target companies in our
market with large numbers of email customers which will enable us to expand our
customer base. Second, we will evaluate companies that help us augment our
service offerings for our current and future email customers. In addition,
these value-added services may be used by customers not using our basic email
service to enhance the functionality of their email services. Examples of
services that we may provide include: unified messaging, guaranteed delivery,
digital certificates and calendaring.

  Develop and Leverage Strategic Relationships

  We intend to expand our marketing and distribution channels through strategic
relationships with key ISPs, web hosting companies, web portals and
corporations to increase quickly the number of electronic mailboxes we host.
Our strategic partners include ICQ, a subsidiary of America Online, E*TRADE,
Network Solutions, Sprint and U S WEST. We intend to further develop new and
existing strategic relationships to expand our distribution channels and to
undertake joint product development and marketing efforts, such as integrating
email into e-commerce applications.

                                       39

  Increase Sales and Marketing Efforts

  We intend to significantly expand our sales and marketing activities while
focusing on four target markets: ISPs, web hosting companies, web portals and
corporations. In this expansion, we plan to target and hire seasoned sales
professionals with specific expertise and contacts within our focused markets.
We also intend to expand our indirect sales channel by teaming with leading
distributors, resellers and system integrators with strong backgrounds and
market presence. As of March 31, 1999, we had 61 sales and marketing personnel.

  Develop Value-Added Services

  We intend to extend our services beyond email by offering additional value-
added services. These services are intended to extend our relationships with
current customers, to attract new customers and to allow us to differentiate
ourselves in the email service provider market. We believe that our email
hosting solution can form the foundation of a wide range of Internet messaging
applications for which we intend to provide solutions. Examples of value-added
services or applications that can be leveraged are unified messaging, secure
email, e-commerce and enterprise services.

  Expand International Presence

  In addition to expanding our U.S. presence, we believe there is substantial
opportunity for outsourcing messaging services in non-U.S. markets. We intend
to capitalize by developing worldwide sales offices, data centers and strategic
relationships. We have established sales and operations subsidiaries in Germany
and the United Kingdom, and we plan to open data centers in Europe. In
addition, we intend to support our worldwide operations by offering localized
web-based email interfaces. For example, we have already developed web-based
email interfaces in 13 languages and dialects.

Services

  We offer multiple email services to ISPs, web hosting companies, web portals
and corporations. Our "all-in" service model pricing includes all enhancements,
upgrades and new standard features. Pricing is based on a per mailbox, per
month charge that varies depending on functionality and volume. Web portal
market pricing is based on a minimal per mailbox, per month charge plus a share
of revenue generated by advertising on the web-based email interface. Our
standard service offering includes our basic services as part of the monthly
mailbox fee. Our add-ons are included in the basic mailbox offering or offered
as an optional premium service. Our premium services are optional add-ons to
the basic mailbox charge and are offered for an additional charge.

  Our service offering includes web-based end-user support. Additional support
through customer help desks is provided 24 hours a day, seven days a week by
contractual agreement. Professional implementation and transitioning support
for new customers is also included in the basic offering.

  In addition, we plan to initiate email services with Avantel, AsiaMail,
British Telecom, o.tel.o, AOL Latin America, AOL Enterprise and Promus during
the second quarter of 1999.

Target Markets

  We intend to expand our marketing and distribution channels through strategic
relationships to rapidly increase the number of electronic mailboxes hosted. We
have developed strategic relationships within four target markets: ISPs, web
hosting companies, web portals and corporations.

  Internet Service Providers (ISPs)

  Internet service providers are companies that provide access to the Internet.
Email has become an integral part of ISP service offerings. ISPs provide
service via dial-up and ISDN as well as dedicated private-line hookups. For a
monthly fee, customers receive a software package, username, password and
access phone number. Many ISPs offer free home-page hosting to members at the
ISP's domain name (for example, www.ispname.com/~username). Some ISPs are also
providing commercial web hosting (hosting sites at a domain name registered by
the user). ISPs serve large companies by providing a direct connection from the
companies' networks to the Internet.

  Web Hosting Companies

  Web hosting companies offer corporate customers and individual consumers
hosting of their website on a commercial web server (at a unique domain
registered to the customer). In addition,

                                       44
<PAGE>

web hosting companies are increasingly offering web design, domain name
registration service and email services to their customers. We believe that
most business customers are looking for a full-service web hosting company that
can provide domain name registration, basic website services and enhanced
website services including e-commerce and messaging.

  Web Portals

  Web portals include online communities and search engines which offer a one-
stop source of information to a broad range of users, and vertical portals,
such as E*TRADE, which cater to the needs of a specific audience. The goal of
portal sites is to develop a sense of community in order to draw large online
audiences, encourage repeat visits, and keep users engaged. Portals are
accomplishing this goal by providing users with value-rich content and services
such as search engines, free individual homepages and free email. The majority
of a portal's revenue comes from advertising targeting its large, demographic-
specific audience and repeat website visits.

  Corporations

  Email has become a mission-critical application for businesses. Many U.S.-
based corporations of varying sizes use email as a primary form of
communication. In addition, the ability to access Internet-based email from
outside the office has added to email's appeal and utility for corporations. A
large percentage of the corporate market's email is supplied internally via LAN
mail systems. Companies are struggling with aging LAN-based systems designed in
the late 1980s and early 1990s when email was used on a much more casual basis
and by a smaller user population. Until recently, Internet standards-based
email has accounted for only a small portion of corporate messaging systems,
but according to Internet Week, that portion will increase to one-third of the
corporate market by the end of the decade.

Strategic Relationships

  A key element of our strategy is to expand our marketing and distribution
channels through strategic relationships with entities that are both commercial
partners and/or equity investors or entities with whom we have contractualized
reseller relationships. We believe that these strategic relationships will
enable us to expand our distribution channels and to undertake joint product
development and marketing efforts. The following are examples of our existing
strategic relationships which we believe will position us to increase quickly
the number of electronic mailboxes we host.

  America Online/ICQ

  In January 1999, we entered into an agreement with ICQ, a subsidiary of
America Online, pursuant to which we will provide email hosting services that
will be integrated with ICQ's instant messaging service provided to ICQ's
customers. The ICQ instant messaging service allows users to communicate in
real time over the Internet. Our agreement with ICQ also provides for our
integration of features of the ICQ instant messaging service with our standard
email services and our offering of these integrated services to our other
customers. In April 1999, we expanded our relationship with America Online to
include AOL Latin America and AOL Enterprise.

  E*TRADE Group

  In September 1998, we entered into an agreement with E*TRADE, an on-line
brokerage services company, pursuant to which each party will include the other
in certain advertising campaigns,

                                       45
<PAGE>

including E*TRADE's international and strategic partner relationships. We will
also provide email services to users of E*TRADE's Internet access services.
E*TRADE uses our email services to extend its brand and value-added services to
its fast-growing customer base. As online trading grows, the need for secure
transmissions of trade confirmations grows. In addition, we are in the process
of developing an electronic order confirmation system designed to be SEC
compliant, which could allow online brokerages to conduct most of their
customer communications electronically.

  Network Solutions

  In May 1998, we entered into an agreement with Network Solutions, currently
the exclusive registrar of Internet domain names, pursuant to which we provide
email outsourcing services to users of Network Solutions' website. In exchange
for our services, Network Solutions will provide domain name registration
services for our customers. Through this agreement, a Network Solutions
customer is able to extend its brand using its unique domain name for its email
address instead of the domain name of its Internet access provider.

  Sprint

  In September 1998, we entered into an agreement with Sprint's IP Business
Services pursuant to which we provide email services to Sprint's corporate IP
customers. Sprint has over 7,000 sales representatives who can now offer hosted
email services to their business customers at their own domain name. We provide
a dedicated customer support number and a sales support center to support
Sprint's sales representatives. It is expected that Sprint will integrate our
brand and bill email services under the Sprint name.

  U S WEST

  In December 1998, we entered into an agreement with U S WEST pursuant to
which we provide email services to U S WEST's telephone customers. We believe
that U S WEST views web mail as part of its strategy to offer its telephone
customers value-added Internet services. Web mail is a user-friendly, simple
vehicle to transition telephone customers from dial-tone to web-tone. The
agreement also provides for the enhanced email functionality of US WEST's
!nterprise Internet customers through an email viewer.

  Our agreements with our strategic partners typically are for terms of one to
three years, and automatically renew for additional one-year periods unless
either party gives prior notice of its intention to terminate the agreement. In
addition, these agreements are terminable by our partners without cause, and
some of the agreements are terminable by us without cause upon 30 - 120 days'
notice. Most of the agreements also provide for the partial refund of fees paid
or other monetary penalties in the event that our services fail to meet defined
minimum performance standards. These strategic agreements may be terminated
upon short notice.

Sales and Marketing

  Sales Strategy

  Our sales efforts target all market segment audiences through direct and
indirect channels. We maintain our own direct sales force to introduce and
educate prospective customers and partners about our service. The direct sales
group targets larger ISPs, telecommunications companies, medium to large
corporate customers, large web hosting companies and high-trafficked web
portals. As of

                                       46
<PAGE>

March 31, 1999, we had 20 account executives in the direct sales group, and we
plan to significantly expand this group in the next 12 months. We currently
have domestic offices in the San Francisco, Irvine, San Jose, Seattle, New
York, Phoenix, Denver and Washington D.C. metropolitan areas. We currently have
international offices in Munich, Germany and London, England. Within our direct
sales group, a subgroup is responsible for retaining and increasing use by
existing customers. This group is critical to ensuring customer satisfaction
and selling existing customers new add-on services as they become available in
our service offering.

  A telesales group is located in Phoenix, Arizona and generates and qualifies
leads for referral to the direct sales group. The target markets of the
telesales group are smaller ISPs, web hosting companies and corporations. The
vast majority of the activity generated through this channel results from phone
calls that we initiate to prospective customers. The telesales group also
handles outbound calls to a specific list of contacts provided by our marketing
organization. In addition, the telesales group follows up on leads resulting
from web and telephone communication initiated by prospective customers and
qualifies those leads by placing additional calls or referring them to the
direct sales group.

  The indirect sales channel will use the sales forces of our partners to offer
our services to their end-users. We share revenue with our partners to achieve
this purpose. To gain market presence and market share overseas, we plan to
team with leading distributors, resellers and system integrators that have
strong industry backgrounds and market presence in their respective markets and
geographic regions.

  Marketing Strategy

  Our marketing strategy includes a media relations and public speaking focus
to develop a reputation as an industry leader for email services and messaging.
We will use narrowly focused, co-branded print and online advertising campaigns
for lead generation. Direct marketing will be used to target specific ISP and
web hosting firms. Co-branded and cooperative direct mail will be the
cornerstone of the direct marketing efforts. Event, forum and trade show
participation will also be used to promote our business-to-business brand
presence.

Enhanced Services Development

  Our application management and marketing organizations focus on marketing and
service development. Our application management team monitors new email and
messaging service introductions by our competitors. This in turn assists our
marketing group in determining our application pipeline and feature development
schedules and provides direction for our engineering, operations, sales and
support teams. We also have segment managers for each of our four target
markets who are responsible for defining strategies to address specific needs
within each market. These segment managers work with our technical service
managers, who are in turn responsible for service strategies and development
plans.

  Our service management team focuses on provisioning and billing, mail and
directory services and mail center technology. In addition, the services
management team manages a cross-departmental service development effort. The
development process also includes quality-control steps such as reviews, walk-
throughs and post-implementation audits. The services development process
incorporates input from a variety of sources, including our current and
potential customers, and refines this information through a business
prioritization process. The service management team prepares a marketing
requirements document, which is reviewed by our change control board. The

                                       47
<PAGE>

change control board, which is attended by a cross-department management team,
prioritizes and schedules our development efforts and assigns resources to the
development project team.

  Our services development process involves coordination among our application
management, marketing and service management teams. To support our service
development and marketing functions, we conduct an ongoing analysis of
competitive intelligence, product forecasting, financial analysis and pricing
strategies.

Technology

  In offering email services, we employ advanced software and hardware,
combining internal expertise with industry standard technology to create a
proprietary infrastructure.

  Mail Center Technology

  We have created a proprietary email system, Mail Center Technology ("MCT"),
designed to ensure access to hundreds of millions of mailboxes across millions
of domains. MCT is able to handle high-volume loads for complex and diverse
mail environments such as those required for ISPs, web hosting companies, web
portals and corporations providing email accounts to their end-users for
activities such as trading securities, shopping or participating in online
communities. We have written proprietary load-balancing and email software, and
Oracle Corporation databases are used in account provisioning and management.

  MCT is made up of multiple groups of servers and routers acting as a single,
virtual point of contact to customers for email services. Our MCT hardware
consists of Sun Microsystems, Inc. Ultra Enterprise servers, Cisco Systems,
Inc. routers, Network Appliance, Inc. RAID array storage and rackmounted Intel
processor-based servers running Solaris and FreeBSD, a free operating language.
All aspects of MCT are deployed in pairs with the goal of ensuring that if any
process or system goes down, another will be available to handle customer
traffic seamlessly. This behavior is called "transparent failover," and is
designed to increase the availability of email services to the customer. MCT
also includes a dynamic load-balancing system that acts as proxy servers for
firewall safety. The load balancers are configured in parallel to ensure that
if one goes down, the load is transferred to the remaining systems.

  MCT currently hosts SMTP, POP3 and web-based email services and will also
host IMAP4 and other services as they are released. Both the hardware capacity
and the services hosted by the mail center can be expanded based on customer
demand.

   Simple Mail Transfer Protocol (SMTP)

  SMTP is currently the standard mail protocol for the Internet. It allows
hosts on the Internet to route mail from the sender to the destination. All
Internet messages must be sent using SMTP; older proprietary mail systems must
convert their internal mail formats to SMTP in order to communicate effectively
over the Internet.

   Post Office Protocol (POP)

  With POP, mail is delivered to a shared mail server; users periodically
connect to the server and download all pending mail to their machines.
Thereafter, all mail processing is local to the client machine. POP provides
only the store-and-forward service, moving mail on demand from a mail

                                       48
<PAGE>

server to a single destination machine, usually a PC, Macintosh or UNIX
workstation, and then typically deleting the messages from the POP server.

   Web-based Email

  Web-based email, also known as HTML (Hyper Text Markup Language) email,
allows users to access their mail from any computer with Web browser and
Internet access. This eliminates the need to maintain a separate program for
accessing email.

   Internet Message Access Protocol (IMAP)

  IMAP is more sophisticated than the POP3 protocol and provides greater
flexibility at the server level. This enhanced service allows users to sort
mail by sender and subject, search for specific text, and manipulate folders
and mailboxes while the files remain on the server, rather than downloading
them to their local desktop. This flexibility is particularly valuable for
users who travel frequently and access their mail from a variety of different
computers and email clients.

  Account Provisioning

  We have created a proprietary Account Provisioning Protocol ("APP") for
account creation and maintenance. The APP enables accounts transitioning from
other services or legacy systems to be bulk-loaded, tested, replicated and
deployed on our service automatically. This addresses a critical time to market
issue by enabling organizations to quickly transition to the new standards-
based email service with minimal down-time and degradation to their existing
internal systems. In addition, the APP can be used by customers and partners to
facilitate automatic account sign-ups from websites, typically in less than
three minutes.

  Data Centers and Network Access

  We maintain data centers in San Francisco and Palo Alto, California and
Laurel, Maryland. The data centers have private peering with all major
backbones to allow high-bandwidth access to the Internet. With multiple high-
speed connections to different backbone providers, we have reduced the
likelihood that our customers will suffer downtime as a result of network
outages. Our backbone architecture and interconnection strategy consists of
clear channel DS-3 and OC-3 connections and direct 100 MB/sec Ethernet
connections.

  We currently have bilateral peering arrangements in place with the following
organizations:

<TABLE>
<S>                                <C>                           <C>

Electric Lightwave, Inc.           MAXIM                         XMISSION
</TABLE>

  In addition to our peering connections, we currently purchase additional
Internet access from MCI WorldCom and Sprint, through their relationships with
AboveNet Communications Inc.

  Our data centers feature redundant systems for power, fire protection,
seismic reinforcement, and security surveillance 24 hours a day, seven days a
week by both personnel and video monitors. If we experience service
interruptions on either the East Coast or the West Coast due to a natural

                                       49
<PAGE>

disaster, all Critical Path-hosted messages will be automatically rerouted to
the data center that is not affected. We intend to open data centers in Europe
and Asia. These data centers will add further redundancy and create a local
connectivity in those markets.

  Network Security

  We have created a custom firewall solution to reduce the incidence of network
security breaches, utilizing Cisco Systems, Inc. routers for firewall hardware.
To enhance security for the network, our staff members monitor the network and
hardware 24 hours a day, seven days a week. Any suspicious activity is reported
and investigated immediately.

  Our operations and engineering staffs include many active participants in
open Internet security groups. Newsgroups and industry consortium postings are
actively monitored for information regarding reported security flaws. Suspected
flaws in software and hardware products that could compromise security are
investigated thoroughly and fixes are implemented, often within a matter of
hours.

  The goals of our security efforts are to prevent intruders from gaining
access to our customers' email messages, passwords or financial information, to
protect our server software and design information from being accessed by
intruders, and to prevent malicious individuals from causing service failure or
slowdown. We accomplish these goals by ensuring that our server clusters are
entirely isolated from the Internet at large except for the specific services
we provide, continuously monitoring the network to detect intrusion attempts,
staying up to date on current security issues, and tracking abuse incidents,
such as "spamming," blocking as necessary, and reporting incidents to the
appropriate originating ISPs.

  Spam Blocking

  Our basic email and web-based email services include comprehensive spam
prevention at no additional charge. This spam prevention is currently being
used to screen messages for all of our service partners and customers.

  Our engineers have written proprietary "learning" software that automatically
screens incoming messages for telltale items in message headers and subject
lines. We have also developed a comprehensive database of commonly forged
addresses and frequently abused domain names. Most additions to the "black
list" have been reported by our end-users, who are encouraged to notify us of
suspected abuse. The black list is actively reviewed to ensure that no
legitimate domains or individual users are blocked from accessing the system or
sending messages.

  In addition to filtering technology at the server level, our personnel
monitor incoming messages 24 hours a day, seven days a week. We are part of a
group of key network operators and ISPs working to develop technologies and
other measures aimed at protecting users from junk email. We have
representatives serving on the Coalition Against Unsolicited Commercial Email,
the leading national organization lobbying for anti-spam legislation. Our
Acceptable Use Policy explicitly states that partners and customers may not use
our service to send unsolicited bulk email.

Customer Support

  We provide customer support 24 hours a day, seven days a week by contractual
agreement. Our customer support service consists of two tiers. Tier 1 includes
technical support in response to end- user inquiries. Although our customers
typically provide Tier 1 support directly to their end-

                                       50
<PAGE>

users, they can outsource this function to us and we can provide Tier 1 support
to their end-users via email or web-based support. We also provide support
information on our website.

  Tier 2 support includes technical support, provided to our ISP, web hosting,
web portal and corporate customers, via toll-free access and email
correspondence managed by our team of trained technical support
representatives. Our technical support representatives include pooled and
dedicated representatives. Pooled representatives are trained to resolve the
majority of inquiries and, where necessary, to escalate and manage inquiries
through to resolution. Dedicated representatives must meet stringent technical
criteria, are assigned to strategic accounts and assist in identifying and
qualifying new features and functionality in addition to advanced problem
solving.

  In an effort to further improve customer satisfaction, we are deploying new
tools designed to allow customers to track the status of their open tickets and
access standard reported metrics through a secure web interface. These tools
will also facilitate our ability to track recurring customer issues that will
identify opportunities for service improvements. Our staff of trained technical
representatives, coupled with leading edge monitoring and tracking tools allows
us to successfully serve the needs of our clients.

Competition

  The market for Internet-based email service is characterized by companies
that elect to develop and maintain in-house solutions and companies that seek
outsourcing arrangements for their email service. For customers seeking
outsourcing arrangements, we compete with email service providers, such as
USA.NET, and mail.com, as well as product-based companies, such as Software.com
and Lotus Development Corporation. In addition, companies such as Software.com,
Microsoft, Lotus and Sun Microsystems are currently offering email products
directly to ISPs, web hosting companies, web portals and corporations. These
companies could potentially leverage their existing capabilities and
relationships to enter the email service industry by redesigning their system
architecture, pricing and marketing strategies to sell through to the entire
market. In the future, ISPs, web hosting companies and outsourced application
companies may broaden their service offerings to include outsourced email
solutions.

  The level of competition is likely to increase as current competitors
increase the sophistication of their offerings and as new participants enter
the market. In the future, as we expand our service offerings, we expect to
encounter increased competition in the development and delivery of these
services. Many of our current and potential competitors have longer operating
histories, larger customer bases, greater brand recognition and significantly
greater financial, marketing and other resources than we do and may enter into
strategic or commercial relationships with larger, more established and well-
financed companies. Certain of our competitors may be able to enter into such
strategic or commercial relationships on more favorable terms. Further, certain
of our competitors may offer services at or below cost. In addition, new
technologies and the expansion of existing technologies may increase
competitive pressures on us. Increased competition may result in reduced
operating margins and loss of market share. We believe that our service
solution competes favorably with that of other providers with respect to the
following:

  . providing cost savings over in-house solutions by relieving customers of
    expenses associated with acquiring and maintaining hardware and software
    and the associated administrative burden;

  . providing greater functionality and access to leading technologies and
    protocols, which in turn enables customers to choose the protocol that
    best suits their end-users' needs;

                                       51
<PAGE>

  . enabling customers to maintain brand control, thereby enhancing their
    brand identity; and

  . facilitating scalability through an infrastructure designed to support
    hundreds of millions of mailboxes across millions of domains.

  However, despite our competitive positioning, we may not be able to compete
successfully against current and future competitors, and competitive pressures
we face could have a material adverse effect on our business, operating results
and financial condition.

Intellectual Property

  We regard our copyrights, service marks, trademarks, trade secrets and
similar intellectual property as critical to our success, and rely on trademark
and copyright law, trade secret protection and confidentiality and/or license
agreements with our employees, customers, partners and others to protect our
proprietary rights. We have no registered trademarks or service marks to date.
It may be possible for unauthorized third parties to copy certain portions of
our products or reverse engineer or obtain and use information that we regard
as proprietary. Certain end-user license provisions protecting against
unauthorized use, copying transfer and disclosure of the licensed program may
be unenforceable under the laws of certain jurisdictions and foreign countries.
We have one patent pending in the United States. We do not know whether this
patent will be granted or, that if granted, that the patent will not be
challenged or invalidated. In addition, the laws of some foreign countries do
not protect proprietary rights to the same extent as do the laws of the United
States. There can be no assurance that our means of protecting our proprietary
rights in the United States or abroad will be adequate or that competing
companies will not independently develop similar technology.

  Other parties have asserted and may assert, from time to time, infringement
claims against us. We may also be subject to legal proceedings and claims from
time to time in the ordinary course of our business, including claims of
alleged infringement of the trademarks and other intellectual property rights
of third parties by us and our licensees. For example, we recently received a
letter alleging that our name infringed the trade name of another company. Such
claims, even if not meritorious, could result in the expenditure of significant
financial and managerial resources.

  We also intend to continue to strategically license certain technology from
third parties, including our web server and SSL encryption technology. In the
future, if we add certificate technology to our systems, we may license
additional technology from third-party vendors. We cannot be certain that these
third-party content licenses will be available to us on commercially reasonable
terms or that we will be able to successfully integrate the technology into our
products and services. These third-party in-licenses may expose us to increased
risks, including risks associated with the assimilation of new technology, the
diversion of resources from the development of our own proprietary technology
and our inability to generate revenues from new technology sufficient to offset
associated acquisition and maintenance costs. The inability to obtain any of
these licenses could result in delays in product and service development until
equivalent technology can be identified, licensed and integrated. Any such
delays in services could cause our business, financial condition and operating
results to suffer. See "Risk Factors--We have limited protection of our
intellectual property and proprietary rights."

Government Regulation

  Although there are currently few laws and regulations directly applicable to
the Internet and commercial email services, it is possible that a number of
laws and regulations may be adopted with

                                       52
<PAGE>

respect to the Internet or commercial email services covering issues such as
user privacy, pricing, content, copyrights, distribution, antitrust and
characteristics and quality of products and services. Further, the growth and
development of the market for online email may prompt calls for more stringent
consumer protection laws that may impose additional burdens on those companies
conducting business online. The adoption of any additional laws or regulations
may impair the growth of the Internet or commercial online services, which
could, in turn, decrease the demand for our products and services and increase
our cost of doing business, or otherwise have a material adverse effect on our
business, operating results and financial condition. Moreover, the
applicability to the Internet of existing laws in various jurisdictions
governing issues such as property ownership, sales and other taxes, libel and
personal privacy is uncertain and may take years to resolve. Any such new
legislation or regulation, the application of laws and regulations from
jurisdictions whose laws do not currently apply to our business or the
application of existing laws and regulations to the Internet could have a
material adverse effect on our business, operating results and financial
condition. See "Risk Factors--We face risks associated with government
regulation and legal uncertainties."

Employees

  As of March 31, 1999, we had 182 full-time employees. None of our employees
is covered by collective bargaining agreements. We believe that our relations
with our employees are good.

Facilities

  Our principal executive offices are located in San Francisco, California, in
a 31,500 square foot facility under a lease expiring on June 30, 2002, with a
five-year renewal option and a sublease expiring on March 31, 2002. We believe
that our facilities will be adequate for the next 12 months. However, we may
not be able to lease additional space on commercially reasonable terms or at
all.

Legal Proceedings

  Critical Path is engaged from time to time in litigation arising in the
ordinary course of its business. For example, we were recently sued by
CustomTracks Corporation, which asserted several claims including breach of
contract, misappropriation of trade secrets and certain other claims. The suit
seeks unspecified monetary damages and a injunction to enjoin Critical Path
from using the information that was allegedly misappropriated. We believe that
we have meritorious defenses to these suits and intend vigorously to defend
ourself against these suits.

(1) Based on options to purchase an aggregate of 10,595,453 shares of common
    stock granted during fiscal 1998. Under the terms of Critical Path's 1998
    Stock Plan, the committee designated by the board of directors to
    administer the 1998 Stock Plan retains the discretion, subject to certain
    limitations within the 1998 Stock Plan, to modify, extend or renew
    outstanding options and to reprice outstanding options. Options may be
    repriced by canceling outstanding options and reissuing new options with an
    exercise price equal to the fair market value on the date of reissue, which
    may be lower than the original exercise price of such canceled options. See
    "Stock Plans."

(2) The exercise price on the date of grant was equal to 100% of the fair
    market value on the date of grant as determined by the board of directors.

(3) The 5% and 10% assumed rates of appreciation are mandated by the rules of
    the Securities and Exchange Commission and do not represent Critical Path's
    estimate or projection of the future common stock price. There can be no
    assurance that any of the values reflected in the table will be achieved.
    Assumes a per share fair market value equal to the initial public offering
    price of $24.00.

(5) This non-statutory stock option has a 10-year term, subject to earlier
    termination in certain events related to termination of employment, and
    vests as to 1/48th of the shares per month over a four-year period. This
    option provides for partial acceleration of vesting upon change of control
    of Critical Path, and an early exercise provision. In November 1998 this

1998 Stock Plan

  Our 1998 Stock Plan was adopted by the board of directors on January 21,
1998, amended on December 15, 1998 and was amended and restated effective upon
completion of our initial public offering. Our 1998 Stock Plan provides for
awards or sales of shares and options (including incentive stock options
("ISOs") and nonstatutory stock options ("NSOs")). Employees, consultants and
advisors of Critical Path are eligible for all awards except ISOs. Only
employees are eligible for the grant of ISOs. A total of 12,288,741 shares of
common stock has been reserved for issuance under our 1998 Stock Plan and this
amount is increased by 5% each January 1, commencing January 1, 2000.

  Our 1998 Stock Plan is administered by our compensation committee and our
non-insider option committee. Our compensation committee consists of at least
two directors who are "non-employee directors," as defined in Rule 16b-3. Our
non-insider option committee consists of our chief executive officer, and is
authorized to grant options to persons who are not executive officers. The
board of directors may amend our 1998 Stock Plan as desired without further
action by Critical Path's shareholders except as required by applicable law.
Our 1998 Stock Plan will continue in effect until terminated by the board or
for a term of 10 years from its original adoption date, whichever is earlier.

  The consideration for each award under our 1998 Stock Plan is established by
the compensation committee, but in no event will the option price for ISOs be
less than 100% of the fair market value of the stock on the date of grant.
Awards will have such terms and be exercisable in such manner and at such times
as the compensation committee may determine. However, each ISO must expire
within a period of not more than 10 years from the date of grant.

  Our 1998 Stock Plan provides that, in the event of a merger or reorganization
of Critical Path, outstanding options and restricted shares shall be subject to
the agreement of merger or reorganization.

  As of March 31, 1999, 13,244,465 awards had been granted under our 1998 Stock
Plan. Such options have exercise prices ranging from $0.02 to $24.00 per share
and a weighted average per share exercise price of $2.71. Options to purchase
2,490,057 shares have been exercised, and 1,026,125 have been cancelled.

Employee Stock Purchase Plan

  The board of directors adopted our Employee Stock Purchase Plan effective
upon completion of our initial public offering. A total of 600,000 shares of
common stock have been reserved for issuance under our Employee Stock Purchase
Plan and this amount will be increased by 5% each January 1 commencing January
1, 2000, up to a maximum of 1,000,000 additional shares. Our Employee Stock
Purchase Plan, which is intended to qualify under Section 423 of the Internal
Revenue Code of 1986, as amended, is administered by the board of directors or
by a committee appointed by the board. Employees (including officers and
employee directors of Critical Path but excluding 5% or greater shareholders)
are eligible to participate if they are customarily employed for at least 20
hours per week and for more than five months in any calendar year. Our Employee
Stock Purchase Plan permits eligible employees to purchase common stock through
payroll deductions, which may not exceed 15% of an employee's compensation.

  Our Employee Stock Purchase Plan is implemented in a series of overlapping
24 month participation periods. The initial participation period commenced on
the effectiveness of our initial public offering and ends on April 30, 2001.
Subsequent 24 month participation periods will commence on November 1, 1999 and
each May 1 and November 1 thereafter. Purchases will occur on each April 30 and
October 31 (the "purchase dates") during each participation period, excluding
April 30, 1999. If on any purchase date during a participation period the fair
market value of a share of common stock is less than the fair market value on
the commencement of the participation period, the participation period shall be
terminated immediately following such purchase date. The employees who had
enrolled in the terminated participation period shall automatically be enrolled
in the participation period commencing on the day after the purchase date.

  The purchase price of the common stock under our Employee Stock Purchase Plan
will be equal to 85% of the fair market value per share of common stock on
either the start date of the participation period or on the purchase date,
whichever is less. Employees may end their participation in an participation
period at any time during that period, and participation ends automatically on
termination of employment with Critical Path. In the event of a proposed
dissolution or liquidation of Critical Path, the offering periods terminate
immediately prior to the consummation of the proposed action, unless otherwise
provided by the board. If there is a proposed sale of all or substantially all
of Critical Path's assets or the merger of Critical Path with or into another
corporation, then the offering period in progress will be shortened and a new
exercise date will be set that is before the sale or merger. The offering
period in progress shall end on the new exercise date. Each participant shall
be notified at least ten business days prior to the new exercise date, and
unless such participant ends his or her participation, the option will be
exercised automatically on the new exercise date.

401(k) Plan

  Critical Path has established a tax-qualified employee savings and retirement
plan (the "401(k) Plan") for which all of Critical Path's employees are
eligible except for employees subject to a collective bargaining agreement and
nonresident aliens with no U.S. source income. Pursuant to the 401(k) Plan,
employees may elect to reduce their current compensation by up to the lower of
15% or the statutorily prescribed limit and have the amount of such reduction
contributed to the 401(k) Plan. The 401(k) Plan permits additional
discretionary matching contributions by Critical Path. To date, Critical Path
has made no such matching contributions. The 401(k) Plan is intended to qualify
under

                                       61
<PAGE>

Section 401 of the Internal Revenue Code of 1986, as amended, so that
contributions by employees or by Critical Path to the 401(k) Plan, and income
earned on plan contributions, are not taxable to employees until withdrawn from
the 401(k) Plan, and so that contributions by Critical Path, if any, will be
deductible by Critical Path when made.

Employment Agreement and Change in Control Arrangements

  Critical Path does not currently have any employment contracts in effect with
any of the Named Executive Officers other than Douglas T. Hickey, its
President, Chief Executive Officer and director.

  Critical Path and Mr. Hickey are parties to a letter agreement dated October
1, 1998 governing his employment with Critical Path. The agreement sets forth
Mr. Hickey's compensation level and eligibility for salary increases, bonuses,
benefits and option grants under the 1998 Stock Plan. The agreement provides
for accelerated vesting of a portion of Mr. Hickey's options in the event of a
change of control. Mr. Hickey also received a loan in the amount of $500,000,
bearing interest at the applicable federal rate. The loan will be due on the
earlier of five years or 30 days following termination of his employment and is
non-recourse unless Mr. Hickey terminates his employment voluntarily. Mr.
Hickey's employment under the letter agreement is at-will and may be terminated
by Critical Path or Mr. Hickey at any time, with or without cause and with or
without notice.

Limitation of Liability and Indemnification Matters

  Critical Path's articles of incorporation limit the liability of directors to
the maximum extent permitted by California law. This limitation of liability is
subject to exceptions including intentional misconduct, obtaining an improper
personal benefit and abdication or reckless disregard of director duties.
Critical Path's articles of incorporation and bylaws provide that Critical Path
may indemnify its directors, officers, employees and other agents to the
fullest extent permitted by law. Critical Path's bylaws also permit it to
secure insurance on behalf of any officer, director, employee or other agent
for any liability arising out of his or her actions in such capacity,
regardless of whether the bylaws would permit indemnification.

  Critical Path has entered into agreements to indemnify its directors and
executive officers, in addition to indemnification provided for in Critical
Path's bylaws. These agreements, among other things, provide for
indemnification of Critical Path's directors and executive officers for certain
expenses (including attorneys' fees), judgments, fines and settlement amounts
incurred by any such person in any action or proceeding, including any action
by or in the right of Critical Path, arising out of such person's services as a
director or executive officer of Critical Path, any subsidiary of Critical Path
or any other company or enterprise to which the person provides services at the
request of Critical Path. Critical Path believes that these provisions and
agreements are necessary to attract and retain qualified persons as directors
and executive officers.

majority of the disinterested independent directors, are on terms no less
favorable to Critical Path than could be obtained from unaffiliated parties and

                          DESCRIPTION OF CAPITAL STOCK

  Our authorized capital stock consists of 150,000,000 shares of common stock,
par value $0.001 and 5,000,000 shares of preferred stock, par value $0.001. The
following summary of certain provisions of our common stock, preferred stock,
amended and restated articles of incorporation and bylaws is qualified in its
entirety by reference to our amended and restated articles of incorporation and
bylaws, which have been filed as exhibits to the registration statement of
which this prospectus is a part.

Common Stock

  As of May 26, 1999, there were 35,124,532 shares of common stock outstanding,
held by approximately 369 shareholders of record.

  Holders of our common stock are entitled to one vote for each share held of
record on all matters submitted to a vote of the shareholders, including the
election of directors, and do not have cumulative voting rights. Subject to
preferences that may be applicable to any then outstanding preferred stock,
holders of common stock are entitled to receive ratably such dividends, if any,
as may be declared by the board of directors out of funds legally available
therefor. See "Dividend Policy." Upon a liquidation, dissolution or winding up
of Critical Path, the holders of common stock will be entitled to share ratably
in the net assets legally available for distribution to shareholders after the
payment of all debts and other liabilities of Critical Path, subject to the
prior rights of any preferred stock then outstanding. Holders of common stock
have no preemptive or conversion rights or other subscription rights and there
are no redemption or sinking funds provisions applicable to the common stock.
All outstanding shares of common stock are, and the common stock to be
outstanding upon completion of this offering will be, fully paid and
nonassessable.

Preferred Stock

  Our board of directors has the authority, without further action by the
shareholders, to issue from time to time the preferred stock in one or more
series and to fix the number of shares, designations, preferences, powers and
relative, participating, optional or other special rights and the
qualifications or restrictions thereof. The preferences, powers, rights and
restrictions of different series of preferred stock may differ with respect to
dividend rates, amounts payable on liquidation, voting rights, conversion
rights, redemption provisions, sinking fund provisions and purchase funds and
other matters. The issuance of preferred stock could decrease the amount of
earnings and assets available for distribution to holders of common stock or
affect adversely the rights and powers, including voting rights, of the holders
of common stock, and may have the effect of delaying, deferring or preventing a
change in control of Critical Path. We currently do not plan to issue any
shares of preferred stock.

Registration Rights

  The holders of 26,695,465 shares of common stock have the right to cause us
to register their shares of common stock, as follows:

  . Demand Registration Rights: After September 25, 1999, the holders can
    send a written request to Critical Path to register their shares with
    respect to all or a part of their registrable securities having an
    aggregate proceeds, net of underwriting discounts and expenses, exceeding
    $12,500,000 and an initial offering price of at least $2.88 per share (as
    adjusted for

                                       69
<PAGE>

   splits or the like). The initial offering price of $2.88 per share is
   equal to four times the price per share of the Series A Preferred Stock,
   which was $0.72. The $12,500,000 aggregate proceeds threshold was
   negotiated as part of the Series A Preferred Stock financing.

  . Piggyback Registration Rights: The holders can request to have their
    shares registered anytime Critical Path is filing a registration
    statement to register any of our securities for our own account. Such
    registration opportunities are unlimited but the number of shares that
    can be registered may be eliminated entirely or cut back in certain
    situations by the underwriters.

  . S-3 Registration Rights: The holders of at least 20% of the registrable
    securities can request Critical Path to register their shares if Critical
    Path is eligible to use Form S-3 and if the aggregate price of the shares
    to the public is at least $1,000,000. The Form S-3 registration
    opportunities are not limited.

  All of the holders of registrable securities may sell their shares after
September 25, 1999, subject to volume limitations, the expiration of
applicable holding periods under Rule 144 under the Securities Act and our
right to repurchase unvested shares.

  The registration rights terminate the earlier of 5 years following the
closing of our initial public offering or when Rule 144 becomes available for
the sale of all of the registrable shares during any 90 day period.

Antitakeover Effects of Provisions of Articles of Incorporation and Bylaws

  Our articles of incorporation and bylaws authorize us to indemnify our
current and former directors, officers, employees or agents to the fullest
extent permitted by law. Our articles of incorporation eliminate a director's
liability for monetary damages to the fullest extent permitted by the
California Corporations Code. We believe that these provisions will assist us
in attracting or retaining qualified individuals to serve as directors and
officers.

  Articles of Incorporation

  Under our articles of incorporation, the board of directors has the power to
authorize the issuance of up to 5,000,000 shares of preferred stock and to
determine the price, rights, preferences, privileges and restrictions,
including voting rights, of those shares without further vote or action by the
shareholders. The issuance of preferred stock, while providing desirable
flexibility in connection with possible acquisitions and other corporate
purposes, may delay, defer or prevent a change in control of Critical Path,
may discourage bids for the common stock at a premium over the market price of
the common stock and may adversely affect the market price of and the voting
and other rights of the holders of the common stock. These provisions are
intended to:

  . enhance the likelihood of continuity and stability in the composition of
    the board of directors and in the policies formulated by the board of
    directors,

  . discourage certain types of transactions that may involve an actual or
    threatened change of control of Critical Path,

  . reduce the vulnerability of Critical Path to an unsolicited acquisition
    proposal, and

  . discourage certain tactics that may be used in proxy fights.

  These provisions, however, could have the effect of discouraging others from
making tender offers for our shares and, as a consequence, they also may
inhibit fluctuations in the market price of

                                      70
<PAGE>

our shares that could result from actual or rumored takeover attempts. These
provisions also may have the effect of preventing changes in our management.

  Our articles of incorporation provide that our bylaws may be repealed or
amended only by a two-thirds vote of the board of directors or a two-thirds
shareholder vote and that all shareholder action be taken at a shareholders'
meeting. These provisions of the articles of incorporation may only be amended
or repealed by the holders of at least two-thirds of the voting power of all
the then-outstanding shares of stock entitled to vote generally for the
election of directors voting together as a single class.

  Bylaws

  Our bylaws provide for a board that consists of a range of authorized
directors from four to seven, which exact number can be set and amended from
time to time by our board. The directors will be elected at the annual meeting
of shareholders or any special meeting of shareholders and each director so
elected will hold office until the next annual meeting or until his successor
is duly elected and qualified or until his earlier resignation or removal. The
shareholders may not cumulate their votes in the election of directors when we
become a listed company under Section 301.5(d) of the California Corporations
Code. Unless otherwise restricted by statute, our articles of incorporation or
our bylaws, any director or the entire board may be removed, with or without
cause, by the holders of at least two-thirds of the shares entitled to vote at
an election of directors. Vacancies may be filled by a majority of the
directors then in office or by a sole remaining director.

  Special meetings of shareholders may be called by the board of directors, the
chairman of the board, the chief executive officer and president, or by the
holders of shares entitled to cast no less than 10% of the votes at the
meeting. The notice of any special meeting must specify the general nature of
the business to be transacted and no other business may be transacted at such
meeting.

  The bylaws may be amended or repealed by the affirmative vote of two-thirds
of the outstanding shares entitled to vote or by the board of directors. The
provisions described above, together with the ability of the board of directors
to issue preferred stock as described above, may deter a hostile takeover or
delay a change in control or management of Critical Path. See "Risk Factors--
Our articles of incorporation and bylaws contain provisions which could delay
or prevent a change of control."

  Transactions Involving Interested Parties Under California Law

  Section 1203 of the California Corporations Code requires delivery of a
report of an independent appraiser to shareholders in certain reorganizations,
tender offers and cash-for-asset sales proposed by an interested party. The
report must include an opinion as to the fairness of the consideration. An
interested party is a person who indirectly or directly controls the subject
corporation, is directly or indirectly controlled by an officer or director of
the subject corporation or is an entity in which a material financial interest
is held by any director or executive officer of the corporation.

Transfer Agent and Registrar

  The transfer agent and registrar for our common stock is American Securities
Transfer & Trust.

                        SHARES ELIGIBLE FOR FUTURE SALE

  Upon completion of this offering, we will have 38,124,532 shares of common
stock outstanding based on 35,124,532 shares outstanding at May 26, 1999. The
3,500,000 shares of common stock being sold hereby will be freely tradable,
other than by our "affiliates" as such term is defined in the Securities Act,
without restriction or registration under the Securities Act. Approximately
29.4 million shares of our common stock were issued and sold by us in private
transactions and are restricted shares. These shares are eligible for public
sale if registered under the Securities Act or sold in accordance with Rules
144 or 701 under the Securities Act.

  All restricted shares are subject to lock-up agreements with the underwriters
under which the holders of the restricted shares have agreed they will not sell
any common stock owned by them without the prior written consent of the
representatives of the underwriters until September 25, 1999. Beginning on
September 26, 1999, these shares will be eligible for resale into the public
market, subject to volume limitations, the expiration of applicable holding
periods under Rule 144 and our right to repurchase unvested shares.

  Subject to limitations on the aggregate offering price of a transaction and
other conditions, Rule 701 may be relied upon with respect to the resale of
securities originally purchased from us by our employees, directors, officers,
consultants or advisers prior to the closing of this offering, pursuant to
written compensatory benefit plans or written contracts relating to the
compensation of such persons. Securities issued in reliance on Rule 701 are
deemed to be restricted shares and, beginning 91 days after March 26, 1999,
unless subject to the contractual restrictions described above, may be sold by
persons other than affiliates subject only to the manner of sale provisions of
Rule 144 and by affiliates under Rule 144 without compliance with its one-year
minimum holding period requirements.

  In general, under Rule 144 as currently in effect, beginning September 26,
1999, a person (or persons whose shares are aggregated) who has beneficially
owned restricted securities 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:

  . 1% of the then outstanding shares of common stock, approximately 381,245
    shares immediately after this offering, or

  . the average weekly trading volume of the common stock during the four
    calendar weeks preceding the date on which notice of the sale is filed
    with the Securities and Exchange Commission.

  Sales under Rule 144 are subject to certain requirements relating to manner
of sale, notice and availability of current public information about us.
However, if a person (or persons whose shares are aggregated) is not deemed to
have been our affiliate at any time during the 90 days immediately preceding
the sale, he or she may sell his or her restricted shares under Rule 144(k)
without regard to the limitations described above if at least two years have
elapsed since the later of the date the shares were acquired from us or from
our affiliate. The foregoing is a summary of Rule 144 and is not intended to be
a complete description of it.

  We intend to file a registration statement under the Securities Act covering
approximately 12,288,741 shares of common stock reserved for issuance under the
1998 Stock Plan. This registration statement is expected to be filed soon after
the date of this prospectus and will automatically become effective upon
filing. Shares registered under this registration statement will be available
for sale in the open market, unless the shares are subject to vesting
restrictions with us or the contractual restrictions described above.

  We also intend to register an aggregate of 600,000 shares of common stock
reserved for issuance under our 1999 Employee Stock Purchase Plan.

</TABLE>

  The underwriters' representatives have advised us that 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 certain
dealers at such price less a concession of not in excess of $1.33 per share, of
which $0.10 may be reallowed to other dealers. After the public offering, the
public offering price, concession, and reallowance to dealers may be reduced by
the underwriters' representatives. No such reduction shall change the amount of
proceeds to be received by us as set forth on the cover page of this
prospectus.

  E*OFFERING is facilitating the distribution of shares sold in the offering
over the Internet.

  The selling shareholders have granted to the underwriters an option,
exercisable during the 30-day period after the date of this prospectus, to
purchase up to 525,000 additional shares of common stock at the same price per
share as will be paid for the 3,500,000 shares that the underwriters have
agreed to purchase. To the extent that the underwriters exercise such option,
each of the underwriters will have a firm commitment to purchase approximately
the same percentage of such additional shares that the number of shares of
common stock to be purchased by it shown in the above table represents as a
percentage of the 3,500,000 shares offered hereby. If purchased, such
additional shares will be sold by the underwriters on the same terms as those
on which the 3,500,000 shares are being sold.

  Because E*TRADE Group, an affiliate of E*OFFERING, holds more than 10% of our
common stock, E*TRADE Group may be deemed to have a conflict of interest with
us. Consequently, the offering will be conducted in accordance with Conduct
Rule 2720 of the National Association of Securities Dealers, Inc., which
requires that the public offering price of any equity security be no higher
than the price recommended by a qualified independent underwriter that has
participated in the preparation of the registration statement and performed its
usual standards of due diligence with respect to the registration statement.
BancBoston Robertson Stephens Inc. has agreed to act as qualified independent
underwriter with respect to the offering, and the public offering price of the
common stock will be no higher than that recommended by BancBoston Robertson
Stephens Inc.

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

                                       73
<PAGE>

  Our directors, officers and certain of our other shareholders have each
agreed that, without the prior written consent of BancBoston Robertson Stephens
Inc. on behalf of the underwriters, until September 25, 1999, they will not,
directly or indirectly:

  . Offer, pledge, sell, contract to sell, sell any option or contract to
    purchase, purchase any option or contract to sell, grant any option,
    right or warrant to purchase, lend or otherwise transfer or dispose of,
    directly or indirectly, any shares of common stock or any securities
    convertible into or exercisable or exchangeable for common stock (whether
    such shares or any such securities are then owned by such person or are
    thereafter acquired directly from us); or

  . Enter into any swap or other arrangement that transfers to another, in
    whole or in part, any of the economic consequences of ownership of common
    stock;

whether any such transaction described above is to be settled by delivery of
common stock or such other securities, in cash or otherwise.

  The restrictions described in the previous paragraph do not apply to

  . the sale to the underwriters of the shares of common stock under the
    underwriting agreement;

  . the issuance by us of shares of common stock upon the exercise of an
    option or a warrant or the conversion of a security outstanding on the
    date of this prospectus which is described in the prospectus;

  . transactions by any person other than us relating to shares of common
    stock or other securities acquired in open market transactions after the
    completion of the offering of the shares of common stock; or

  . issuances of shares of common stock or options to purchase shares of
    common stock pursuant to our employee benefit plans as in existence on
    the date of the prospectus and consistent with past practices.

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

Stabilization Disclosure

  The underwriters' representatives have advised us that, pursuant to
Regulation M under the Securities Act, certain persons participating in the
offering may engage in transactions, including stabilizing bids, syndicate
covering transactions or the imposition of penalty bids which may have the
effect of stabilizing or maintaining the market price of the common stock at a
level above that which might otherwise prevail in the open market. A
"stabilizing bid" is a bid for or the purchase of the common stock on behalf of
the underwriters for the purpose of fixing or maintaining the price of the
common stock. A "syndicate covering transaction" is the bid for the purchase of
the common stock on behalf of the underwriters to reduce a short position
incurred by the underwriters in connection with the offering. A "penalty bid"
is an arrangement permitting the underwriters' representatives to reclaim the
selling concession otherwise accruing to an underwriter or syndicate member in
connection with the offering if the common stock originally sold by such
underwriter or syndicate member is purchased by the underwriters'
representatives in a syndicate covering transaction and has therefore not been
effectively placed by such underwriter or syndicate member. The underwriters'
representatives have advised us that such transactions may be effected on the
Nasdaq National Market or otherwise and, if commenced, may be discontinued at
any time.

                                       74

Regulation M/Passive Market Disclosure

  In connection with this offering, certain underwriters and selling group
members (if any) who are qualified market makers on the Nasdaq National Market
may engage in passive market making transactions in our common stock on the
Nasdaq National Market in accordance with Rule 103 of Regulation M under the
Securities Exchange Act, as amended, during the business day prior to the
pricing of the offering before the commencement of offers or sales of the
common stock. Passive market makers must comply with applicable volume and
price limitations and must be identified as such. In general, a passive market
maker must display its bid at a price not in excess of the highest independent
bid of such security; if all independent bids are lowered below the passive
market maker's bid, however, such bid must then be lowered when certain
purchase limits are exceeded.

  Prior Transactions

  In September 1998 and January 1999, Hambrecht & Quist LLC acted as the
placement agent for a private placement of Critical Path's Series B Preferred
Stock. As compensation for its services as placement agent, Hambrecht & Quist
LLC received a cash fee of approximately $1.0 million and warrants to purchase
an aggregate of 121,654 shares of common stock at an exercise price of $4.26
per share, the same price per share paid by all investors who participated in
the private placement. Some entities affiliated with Hambrecht & Quist LLC also
invested in the private placement, purchasing an aggregate of 351,942 shares of
common stock on the same terms and conditions as the other investors in the
private placement, including price per share. In addition, certain affiliates
of E*TRADE Group invested in the private placement, purchasing an aggregate of
82,120 shares of common stock also on the same terms and conditions. Of the
foregoing securities, the NASD has deemed as underwriters' compensation 184,300
shares of common stock and a warrant to purchase an additional 51,364 shares of
common stock held by Hambrecht & Quist LLC and its affiliates, and 82,120
shares of common stock held by certain affiliates of E*TRADE Group.

  Prior to the closing of our initial public offering, Hambrecht & Quist LLC
exercised each of the warrants described above. In addition, Hambrecht & Quist
LLC and persons associated with it entered into written agreements with
Critical Path, whereby Hambrecht & Quist LLC and these associated persons
agreed that, for a period of three years from the effective date of the

                       Report of Independent Accountants

To the Board of Directors and Shareholders
of Critical Path, Inc.

  In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of shareholders' equity (deficit) and of
cash flows present fairly, in all material respects, the financial position of
Critical Path, Inc. and its subsidiary at December 31, 1997 and 1998, and the
results of their operations and their cash flows for the period from February
19, 1997 (Inception) to December 31, 1997 and the year 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

NOTE 1--THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

The Company

  Critical Path, Inc. (the "Company") was incorporated in California on
February 19, 1997 to deliver advanced email hosting services.

Use of estimates

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

Basis of presentation

  The financial statements include the accounts of the Company and its wholly
owned subsidiary. All significant intercompany balances and transactions have
been eliminated in consolidation.

Cash equivalents and restricted cash

  The Company considers all highly liquid investments with an original maturity
of three months or less to be cash equivalents. Cash equivalents consist
primarily of deposits in money market funds. Restricted cash comprises amounts
held on deposit which is required as collateral for Company provided credit
cards.

Concentration of credit risk

  Financial instruments that potentially subject the Company to a concentration
of credit risk consist of cash and cash equivalents, restricted cash and
accounts receivable. Cash and cash equivalents and restricted cash are
deposited with financial institutions that management believes are
creditworthy. The Company's accounts receivable are derived from transactions
with companies throughout the United States. The Company maintains an allowance
for doubtful accounts receivable based upon the expected collectibility of
accounts receivable.

  During the year ended December 31, 1998, approximately 62% and 30% of
revenues before charges related to amortization of the fair value of warrants
issued to customers were derived from the delivery of email services to two
customers. During the three months ended March 31, 1999, these two customers
accounted for approximately 48% (unaudited) and 32% (unaudited) of revenues
before charges related to amortization of warrants.

Fair value of financial instruments

  The Company's financial instruments, including cash and cash equivalents,
restricted cash, accounts receivable, accounts payable and capital lease
obligations, are carried at cost, which approximates fair value due to the
short maturity of these instruments.

                                      F-7

                              CRITICAL PATH, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


Property and equipment

  Property and equipment are stated at cost. Depreciation and amortization is
computed using the straight-line method over the shorter of the estimated
useful lives of the assets, generally three to five years, or the lease term,
if applicable. The Company periodically assesses the recoverability of the
carrying amount of property and equipment and provides for any possible
impairment loss based upon the difference between the carrying amount and the
fair value of such assets. Since February 19, 1997 (Inception) through December
31, 1998, no impairment losses have been identified.

Revenue recognition

  The Company derives revenue through the sale of email hosting services.
Payments for such services are based either on contractual rates per active
mailbox per month, non-refundable fixed payments or as a percentage of customer
generated email advertising revenues. Revenues from contracts specifying a
contractual rate per active mailbox per month are recognized monthly for each
active mailbox covered by the respective contract. Revenues from contracts that
provide non-refundable fixed payments are not dependent upon the active number
of mailboxes and are therefore recognized ratably over the contract term.
Revenues based upon a percentage of customer generated email advertising
revenues are recognized when such revenues are earned and reported by the
customer. Amounts billed or received in advance of service delivery are
recorded as deferred revenue.

  In connection with certain customer contracts, the Company granted warrants
or options to purchase Series B Convertible Preferred Stock to such customers.
The fair value of such warrants or options, determined using the Black-Scholes
option pricing model, is being recognized ratably as a sales discount over the
terms of the respective agreements. See Note 7--Shareholders' Equity.

Research and development

  Research and development costs include expenses incurred by the Company to
develop and enhance its email service offerings and to develop new electronic
messaging services. Research and development costs are expensed as incurred.

Advertising expense

  Advertising costs are expensed as incurred and totaled $0 and $135,000 during
the period from February 19, 1997 (Inception) through December 31, 1997 and the
year ended December 31, 1998, respectively.

  Advertising costs totaled $0 (unaudited) and $18,000 (excluding $7.9 million
of stock-based charges, unaudited) for the three months ended March 31, 1998
and 1999, respectively.

Stock-based compensation

  The Company accounts for stock-based employee compensation arrangements in
accordance with the provisions of Accounting Principles Board ("APB") Opinion
No. 25, "Accounting for

                                      F-8
<PAGE>

                              CRITICAL PATH, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Stock Issued to Employees" and complies with the disclosure provisions of
Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for
Stock-Based Compensation." Under APB 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 of the option. The Company accounts for
equity instruments issued to nonemployees in accordance with the provisions of
SFAS No. 123 and Emerging Issues Task Force ("EITF") 96-18.

Income taxes

  Income taxes are accounted for using an asset and liability approach, which
requires the recognition of taxes payable or refundable for the current year
and deferred tax assets and liabilities for the future tax consequences of
events that have been recognized in the Company's financial statements or tax
returns. The measurement of current and deferred tax assets and liabilities are
based on provisions of the enacted tax law; the effects of future changes in
tax laws or rates are not anticipated. The measurement of deferred tax assets
is reduced, if necessary, by the amount of any tax benefits that, based on
available evidence, are not expected to be realized.

Net loss per share

  Net loss per share is calculated in accordance with SFAS No. 128, "Earnings
per Share" and Securities and Exchange Commission ("SEC") Staff Accounting
Bulletin No. 98 ("SAB 98"). Under the provisions of SFAS No. 128 and SAB 98,
basic net loss per share is computed by dividing the net loss available to
common stockholders for the period by the weighted average number of common
shares outstanding during the period. Diluted net loss per share is computed by
dividing the net loss for the period by the weighted average number of common
and potential common shares outstanding during the period if their effect is
dilutive. Potential common shares comprise restricted Common Stock and
incremental common and preferred shares issuable upon the exercise of stock
options and warrants and upon conversion of Series A and Series B Convertible
Preferred Stock. At December 31, 1998 and March 31, 1999, 28,607,997 and
16,024,637 (unaudited) potential common shares respectively, are excluded from
the determination of diluted net loss per share as the effect of such shares on
a weighted average basis is anti-dilutive.

Pro forma net loss per share (unaudited)

  Pro forma net loss per share for the year ended December 31, 1998 and the
three months ended March 31, 1999 is computed using the weighted average number
of common shares outstanding, including the pro forma effects of the automatic
conversion of the Company's Series A and Series B Convertible Preferred Stock
into shares of the Company's Common Stock as if such conversion occurred at the
beginning of the period, or at date of original issuance, if later. The
resulting pro forma adjustment includes an increase in the weighted average
shares used to compute basic and diluted net loss per share of approximately
10,295,000 shares for the year ended December 31, 1998 and 19,007,000 shares
for the three months ended March 31, 1999. The pro forma effects of these
transactions are unaudited and have been reflected in the accompanying pro
forma consolidated statement of operations.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


Comprehensive income

  Effective January 1, 1998, the Company adopted the provisions of SFAS No.
130, "Reporting Comprehensive Income." SFAS No. 130 establishes standards for
reporting comprehensive income and its components in financial statements.
Comprehensive income, as defined, includes all changes in equity (net assets)
during a period from non-owner sources. To date, the Company has not had any
transactions that are required to be reported in comprehensive income other
than its net loss.

Segment information

  In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information." This
statement establishes standards for the way companies report information about
operating segments in annual financial statements. It also establishes
standards for related disclosures about products and services, geographic areas
and major customers. In accordance with the provisions of SFAS No. 131, the
Company has determined that it does not have separately reportable operating
segments.

Interim Financial Information (Unaudited)

  The accompanying interim consolidated financial statements as of March 31,
1999 and for the three months ended March 31, 1998 and 1999 are unaudited. The
unaudited interim financial statements have been prepared on the same basis as
the annual financial statements and, in the opinion of management, reflect all
adjustments, which include only normal recurring adjustments, necessary to
present fairly the results of the Company's operations and its cash flows for
the three months ended March 31, 1998 and 1999. The financial data and other
information disclosed in these notes to consolidated financial statements
related to these periods are unaudited. The results for the three months ended
March 31, 1999, are not necessarily indicative of the results to be expected
for the year ending December 31, 1999.

Reclassifications

  In the quarter ended March 31, 1999, the Company elected to disclose stock-
based expenses as a separate component of Operating Expenses. Accordingly, for
the year ended December 31, 1998, approximately $148,000, $582,000, and
$1,670,000 have been reclassified from Research and Development, Sales and

Recent accounting pronouncements

  In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position ("SOP") No. 98-1, "Software for Internal Use," which
provides guidance on accounting for the cost of computer software developed or
obtained for internal use. SOP No. 98-1 is effective for financial statements
for fiscal years beginning after December 15, 1998. The Company does not expect
that the adoption of SOP No. 98-1 will have a material impact on its
consolidated financial statements.

NOTE 3--RELATED PARTY TRANSACTIONS:

Notes receivables from shareholders

  At December 31, 1998, the Company had notes receivable from shareholders and
officers of the Company related to purchases of Common Stock in the amount of
$85,000 and $1,066,000 which accrue interest at 5.69% and 4.51% per annum,
respectively. The notes are full recourse and secured

                                      F-11

                              CRITICAL PATH, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

by Common Stock. The notes are due and payable in February 2003 or, for the
$1,066,000 note, 90 days following termination of the officer.

  At December 31, 1998, the Company held a note receivable from an officer
totaling $500,000. The note accrues interest at the rate of 4.51% per annum, is
secured by all shares of the Company's Common Stock held by this individual,
and is due and payable in November 2003 or 30 days following termination.
During the three months ending March 31, 1999, the Company received additional
notes from officers totaling $170,000 (unaudited). These additional notes
accrue interest at the rate of 4.64% per annum, are secured by all shares of
the Company's Common Stock held by the officers and are due and payable in
March 2004 or 30 days following termination.

Revenues

  In April 1998, the Company entered into an email services agreement with a
significant customer, who is also a holder of the Company's Series B Preferred
Stock. Net revenues from this shareholder approximated $605,000 and $552,000
for the year ended December 31, 1998 and the three months ended March 31, 1999,
respectively.

NOTE 4--INCOME TAXES:

  No provision for income taxes was recorded due to the net losses for the
periods from February 19, 1997 (Inception) to December 31, 1998.

  At December 31, 1998, and March 31, 1999, the Company had deferred tax assets
of approximately $4,001,000, and 5,821,000 (unaudited), respectively.
Management believes that, based on a number of factors, it is more likely than
not that the deferred tax assets will not be realized, such that a full
valuation allowance has been recorded. Deferred tax assets relate primarily to
net operating loss carryforwards.

 At December 31, 1998, the Company had approximately $8,803,000 of federal and
state net operating loss carryforwards available to offset future taxable
income. At March 31, 1999 the Company had approximately $14 million (unaudited)
of federal and state net operating loss carryforwards available to offset
future taxable income. Federal and state net operating loss carryforwards
expire in varying amounts beginning in 2012 and 2005, respectively. Under the
Tax Reform Act of 1986, the amounts of and benefits from net operating loss
carryforwards may be impaired or limited in certain circumstances. Events which
cause limitations in the amount of net operating losses that the Company may
utilize in any one year include, but are not limited to, a cumulative ownership
change of more than 50%, as defined, over a three year period.

NOTE 5--BORROWINGS:

Line of credit

  At December 31, 1998, and March 31, 1999 (unaudited), the Company maintained
a revolving line of credit with a bank that provides for borrowings of up to
$1,000,000. The line of credit expires

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

in November 1999 and accrues interest on outstanding borrowings at a rate equal
to the bank's prime rate plus 2.0% (9.75% at December 31, 1998). The line of
credit requires the Company to meet certain financial tests and to comply with
certain other covenants. Borrowings are secured by substantially all of the
assets of the Company. At December 31, 1998, and March 31, 1999 (unaudited),
there were no borrowings outstanding and the Company was in compliance with all
restrictive covenants.

Convertible promissory notes

  At December 31, 1997, the Company had obligations totaling $420,000 under 7%
convertible promissory notes payable to individual investors. In April 1998,
the principal amount of the notes was converted into 582,040 shares of Series A
Convertible Preferred Stock at $0.72 per share.

  In January and February 1998, the Company issued an additional $430,000 of 7%
convertible promissory notes to individual investors. In April 1998, the
principal amount of the notes was converted into 595,897 shares of Series A
Convertible Preferred Stock at $0.72 per share.

Convertible promissory notes--related parties

  At December 31, 1997, the Company had obligations totaling $427,000 under 7%-
10% convertible promissory notes payable to the Company's founder and an
individual associated with the founder. In April 1998, $200,000 of the
principal amount of the notes was converted into 277,162 shares of Series A
Convertible Preferred Stock at $0.72 per share and the remaining balance of
$227,000 was repaid in cash.

  In January and February 1998, the Company issued an additional $70,000 of 7%
convertible promissory notes to a member of the Board of Directors and an
individual associated with the Company's founder. In April 1998, the principal
amount of the notes was converted into 97,006 shares of Series A Convertible
Preferred Stock at $0.72 per share.

NOTE 6--COMMITMENTS:

Leases

  The Company leases office space and equipment under noncancelable operating
and capital leases with various expiration dates through 2002. Rent expense for
the period from February 19, 1997 (inception) to December 31, 1997 and the year
ended December 31, 1998, and the three months ended March 31, 1998 and 1999,
totaled $33,000, $220,000, $22,000 (unaudited), and $84,000 (unaudited),
respectively.

Equipment lease lines

  In April 1998, the Company entered into a financing agreement that provides
for the acquisition of equipment up to $1,000,000. Amounts available under this

for the acquisition of equipment up to $3,500,000 and software and tenant
improvements up to $1,500,000. Amounts available under this agreement are

penalties.

NOTE 7--SHAREHOLDERS' EQUITY:

  As of December 31, 1998, the Company's Articles of Incorporation authorized
the Company to issue 38,636,363 shares of Common Stock at $0.001 par value, and
13,288,519 and 10,000,000 shares of Series A and Series B Convertible Preferred
Stock ("Preferred Stock"), respectively, at $0.001 par value.

Preferred Stock

  On April 1, 1998, the Company completed its Series A Convertible Preferred
Stock ("Series A") financing through the issuance of 12,707,851 shares at a
price per share of $0.72 for net cash proceeds of $7,991,000, and the
conversion of convertible promissory notes payable totaling $1,120,000. The
Company issued an additional 18,013 shares of Series A Preferred Stock to the
convertible promissory note holders upon the exercise of their warrants for
proceeds of $13,000.

  In September 1998, the Company issued 3,636,739 shares of its Series B
Convertible Preferred Stock ("Series B") at $4.26 per share for net proceeds of
approximately $15,441,000.

  The holders of Preferred Stock have various rights and preferences as
follows:

Voting

  Each share of Preferred Stock has voting rights equal to an equivalent number
of shares of Common Stock into which it is convertible and votes together as
one class with Common Stock.

  As long as at least 2,954,545 shares of Preferred Stock remain outstanding,
the Company must obtain approval from a majority of the holders of Preferred
Stock to declare or pay any dividend on Common Stock; redeem, purchase or
otherwise acquire any Common Stock other than shares subject to right of
repurchase by the Company; cause the acquisition, reorganization, merger or
consolidation of the Company that results in a transfer of 50% or more of the
voting control of the Company; authorize or issue another equity security
having a preference over, or being on parity with, the Series A and Series B;
or increase the number of directors of the Company.

  As long as at least 681,818 shares of Preferred Stock remain outstanding, the
Company must obtain approval from a majority of the holders of Preferred Stock
to alter the Articles of Incorporation as it relates to the Preferred Stock or
change the authorized number of shares of Preferred Stock.

Dividends

  Holders of Series A and Series B are entitled to receive noncumulative
dividends at the per annum rate of $0.0577 and $0.34 per share, respectively,
when and if declared by the Board of Directors. The holders of Preferred Stock
will also be entitled to participate in dividends on Common Stock, when and if
declared by the Board of Directors, based on the number of shares of Common
Stock held on an as-if converted basis. No dividends on Preferred Stock or
Common Stock have been declared by the Board of Directors.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


Liquidation

  In the event of any liquidation, dissolution or winding up of the Company,
including a merger, acquisition or sale of assets where the beneficial owners
of the Company's Common Stock and Preferred Stock own less than 51% of the
resulting voting power of the surviving entity, the holders of Series A and
Series B are entitled to receive an amount of $0.72 and $4.26 per share,
respectively, plus any declared but unpaid dividends prior to and in preference
to any distribution to the holders of Common Stock. The remaining assets, if
any, shall be distributed ratably among the holders of Common Stock. Should the
Company's legally available assets be insufficient to satisfy the liquidation
preferences, the funds will be distributed ratably among the holders of
Preferred Stock.

Conversion

  Each share of Preferred Stock is convertible, at the option of the holder,
according to a conversion ratio, subject to adjustment for dilution. Each share
of Preferred Stock automatically converts into the number of shares of Common
Stock into which such shares are convertible at the then effective conversion
ratio upon: (1) the closing of a public offering of Common Stock at a per share
price of at least $15.50 per share with gross proceeds of at least $30,000,000,
or (2) the consent of the holders of the majority of Convertible Preferred
Stock. The initial conversion ratio of Preferred Stock for Common Stock is 1 to
1.

Warrants and Stock Purchase Rights

  In May 1998, the Company issued a right to purchase 454,544 shares of Common
Stock or Preferred Stock in a subsequent financing to a customer as part of an
email services agreement. Under the agreement, the price shall be 80% of the
price at which the stock is sold in the subsequent financing for the initial
227,272 shares and 100% of such price for the remaining 227,272 shares. In
September 1998, the Company completed its initial Series B financing at a per
share price of $4.26. The Company has estimated the fair value of the purchase
right to be $194,000, which will be recognized as a sales discount over the
term of the services agreement. Approximately $136,000 was recognized in 1998.
No warrants were exercised as of December 31, 1998.

  In May 1998, the Company issued to a different customer, a warrant to
purchase up to $250,000 of Preferred Stock in the Company's next financing
round. The warrant is exercisable until December 31, 2001 and the exercise
price per share will equal the price per share at which the Preferred Stock is
sold by the Company. In September 1998, the warrants were exercised in
connection with the Series B financing at a per share price of $4.26. The
Company has estimated the fair value of the warrants approximated $143,000,
which will be recognized as a sales discount over the term of the services
agreement. Approximately $95,000 was recognized in 1998.

  In connection with various financing agreements described in Note 6, the
Company issued warrants to purchase 339,522 share of Series A at $0.72 per
share. The warrants are exercisable for seven years from May 1, 1998, or five
years from the effective date of the Company's initial public offering,
whichever is shorter. As of December 31, 1998, no warrants were exercised.

  In connection with the issuance of certain convertible promissory notes
described in Note 5, the Company issued warrants to purchase 113,636 shares of
Common Stock at $0.02 per share and

241,123 shares of Series A at $0.72 per share. These warrants are exercisable
for one and three years, respectively. The warrants to purchase Common Stock
were exercised in September 1998. At December 31, 1998, warrants to purchase
18,013 shares of Series A had been exercised. The Company estimated the fair
value of the warrants issued at approximately $119,000 which is being amortized
as interest expense.

  In connection with the initial Series B financing, the Company issued
warrants to purchase 70,290 shares of Series B at $4.26 per share to the
placement agent. As of December 31, 1998, no warrants were exercised.

Common Stock purchase agreements

  In February 1998, the Company entered into stock purchase agreements with
three founders and sold 3,863,635 shares of the Company's Common Stock at $0.02
per share. Under the terms of the stock purchase agreements, the Company has
the right to purchase the shares of Common Stock at the original issue price in
the event any one of the founders ceases to be an employee of the Company. The
repurchase rights lapse 25% on the first anniversary of the vesting start date
and ratably each month thereafter for 36 months. In the event of a change in
control of the Company or the closing date of an Initial Public Offering, as
defined, repurchase rights with respect to 50% of the then unvested shares of
Common Stock will lapse. At December 31, 1998, 2,130,680 of these shares of
Common Stock were subject to repurchase rights. In connection with the issuance
of these shares, the Company recorded unearned compensation of $1,306,000 which
is being recognized over the periods in which the Company's repurchase rights
lapse.

  In October 1998, an officer exercised stock options to purchase 1,274,687
shares of the Company's Common Stock at a price of $0.84 per share. Under the
terms of the option, the Company has the right to purchase the unvested shares
of Common Stock at the original issue price in the event the officer ceases to
be an employee of the Company. The repurchase rights lapse ratably each month
for 48 months. At December 31, 1998, 1,221,575 of these shares of Common Stock
were subject to repurchase rights. In connection with the option grant
preceding this transaction, the Company recognized unearned compensation
totaling $3.8 million which is included in the aggregate unearned compensation
charges disclosed in Notes 8 and 9 to these consolidated financial statements.

NOTE 8--STOCK OPTIONS:

  In January 1998, the Company's Board of Directors adopted the 1998 Stock
Option Plan. The Plan provides for the granting of up to 12,288,741 stock
options to employees and consultants of the Company. Options granted under the
Plan may be either incentive stock options ("ISO") or nonqualified stock
options ("NSO"). ISOs may be granted only to Company employees (including
officers and directors who are also employees). NSOs may be granted to Company
employees and consultants.

  Options under the Plan may be granted for periods of up to ten years and at
prices no less than 85% of the estimated fair value of the shares on the date
of grant as determined by the Board of Directors, provided, however, that (i)
the exercise price of an ISO may not be less than 100% of the estimated fair
value of the shares on the date of grant, and (ii) the exercise price of an ISO
granted to

a 10% shareholder may not be less than 110% of the estimated fair value of the
shares on the date of grant. Options generally vest 25% per year and are
exercisable for a maximum period of ten years from the date of grant.

Unearned stock-based compensation

  In connection with certain stock option grants and common stock issuances
during the year ended December 31, 1998, and the three months ended March 31,
1999, the Company recognized unearned compensation totaling $19,882,000 and
$18,108,000, respectively, which is being amortized over the vesting periods of
the related options. Amortization expense recognized during the year ended
December 31, 1998 and the three months ended March 31, 1999, totaled
approximately $2,511,000, and $3,660,000 (unaudited), respectively.

NOTE 9--SUBSEQUENT EVENTS:

Reverse Stock Split

  On March 1, 1999, the Company's Board of Directors approved a 1:2.2 reverse
stock split of the Company's outstanding shares which became effective on March
19, 1999. All share and per share information included in these consolidated
financial statements have been retroactively adjusted to reflect this reverse
stock split.

Series B Convertible Preferred Stock Financing

  In January 1999, the Company completed the second round of the Series B
financing through the issuance of 2,772,708 shares at $4.26 per share for gross
proceeds of approximately $11,817,000. In connection with this financing, the
Company issued warrants to purchase 51,364 shares of Series B at $4.26 per
share to the placement agent.

Exercise of Stock Purchase Rights

  In January 1999, a customer exercised stock purchase rights granted in May
1998 to purchase 454,544 shares of Series B for cash proceeds of approximately
$1,744,000.

Employee Stock Purchase Plan

  In January 1999, the Board of Directors adopted the 1999 Employee Stock
Purchase Plan (the "Purchase Plan") effective on the date of the Offering. The
Purchase Plan reserves 600,000 shares for issuance thereunder. Employees
generally will be eligible to participate in the Purchase Plan if they are
customarily employed by the Company for more than 20 hours per week and more
than five months in a calendar year and are not 5% or greater shareholders.
Under the Purchase Plan, eligible employees may select a rate of payroll
deduction up to 15% of their compensation subject to certain maximum purchase
limitations. The Purchase Plan will be implemented in a series of overlapping
twenty-four month offering periods and beginning on the effective date of the
Offering and subsequent offering periods will begin on the first trading day on
or after May 1 and November 1 of each year. Purchases will occur on each April
30 and October 31 (the "purchase dates") during each participation period.
Under the Purchase Plan, eligible employees will be granted an option to
purchase shares of Common Stock at a purchase price equal to 85% of the fair
market value per share of Common Stock on either the start date of the offering
period or the date on which the option is exercised, whichever is less. If the
fair market value of the Common Stock on any purchase date (other than the
final purchase date) is lower than the fair market value on the start date of
that offering period, then all participants in that offering period will be
automatically withdrawn from such offering period and re-enrolled in the
offering period immediately following.

Stock Option Grants

  In January and March 1999, the Company granted incentive stock options to
employees to purchase 1,789,110 shares of Common Stock at exercise prices
ranging between $3.39 and $7.13 per share. In connection with such option
grants, the Company recognized unearned compensation totaling $18,108,000 which
is being amortized over the four year vesting period of the related options.

Sale of Common Stock

  In January 1999, the Company sold 1,090,909 shares of Common Stock at a price
of $2.20 per share to a customer that also agreed to provide marketing related
services. In connection with the transactions, the Company recognized a charge
totaling $2,247,000 that will be attributed to sales and marketing expense over
the one year term of the agreement.

Common Stock Warrant Issued for Services

  In January 1999, the Company entered into an agreement with ICQ, Inc., a
subsidiary of America Online, Inc., pursuant to which it will provide email
hosting services that will be integrated with ICQ's instant messaging service
provided to ICQ's customers. The ICQ instant messaging service is designed to
allow users to communicate in real time over the Internet. As part of the
agreement, ICQ agreed to provide sub-branded advertising for the Company in
exchange for a warrant to purchase 2,442,766 shares of Series B, issuable upon
attainment of each of five

</TABLE>

  The shares underlying the first milestone were immediately vested on the
effective date of the agreement. The shares underlying the remaining milestones
vest on the dates that ICQ completes registration of the specified number of
sub-branded ICQ mailboxes applicable to each milestone. Using the Black-Scholes
option pricing model and assuming a term of seven years and expected volatility
of 90%, the initial fair value of the warrant on the effective date of the
agreement approximated $16.5 million, which is being amortized to advertising
expense using the straight-line method over four years. The shares underlying
the second through fifth milestones will be remeasured at each subsequent
reporting date until each sub-branded ICQ mailbox registration threshold is
achieved. In the event such remeasurement results in increases or decreases
from the initial fair value, which could be substantial, such increases or
decreases will be recognized immediately, in the event the fair value of the
shares underlying the milestone has been previously recognized, or over the
remaining term.

Revaluation of Common Stock Warrant Issued for Services (unaudited)

  At March 31, 1999, none of the registration milestones specified within the
ICQ warrant agreement had been achieved. Therefore, the shares underlying the
second through fifth milestones of the ICQ warrant were remeasured using the
closing price for our common stock on March 31, 1999 of $77 per share. This
remeasurement resulted in an increase to the fair value of the warrant of
$109.4 million, bringing the total fair value of the warrant to $125.9 million
as of March 31, 1999. This revised fair value will be amortized ratably over
four years, resulting in a quarterly amortization charge to advertising expense
in the amount of $7.9 million beginning in the first quarter of 1999. As noted,
this charge is subject to substantial increase or decrease in future quarters
based upon future changes in the trading price of our common stock.

Initial Public Offering (unaudited)

  On March 29, 1999, the Company completed its initial public offering of
5,175,000 shares of Common Stock (including the exercise of the underwriters
overallotment option) and realized net proceeds of $115.5 million.

Repurchase of Preferred Stock (unaudited)

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Asset Acquisition (unaudited)

  On May 26, 1999, we acquired substantially all the operating assets of the
Connect Service business of Fabrik Communications. The acquisition has been
accounted for using the purchase method of accounting and accordingly, the
purchase price has been allocated to the tangible and intangible assets
acquired on the basis of their respective fair values on the acquisition date.
The total purchase price of $20.1 million consisted of $12.0 million cash and
common stock valued at $8.0 million and other acquisition related expenses of
approximately $100,000. Of the total purchase price, approximately $500,000 was
allocated to property and equipment, and the remainder was allocated to
intangible assets, including customer list ($2.1 million), assembled workforce
($400,000) and goodwill ($17.1 million). The acquired intangible assets will be
amortized over their estimated useful lives of two to three years.

             PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

                                    Overview

  Effective May 26, 1999, the Company acquired substantially all of the
operating assets of the Connect Service business of FABRIK Communications,
Inc., which provides users of local area network e-mail systems a universal
bridge to e-mail users outside their network, including those on the Internet
and all other wide area network e-mail services. The acquisition has been
accounted for using the purchase method of accounting and accordingly, the
purchase price has been allocated to the tangible and intangible assets
acquired on the basis of their respective fair values on the acquisition date.
The fair value of intangible assets was determined based upon a preliminary
valuation using a combination of methods, including a risk-adjusted income
approach for the acquired customer list and replacement cost approach for the
value of the assembled workforce.

  The total purchase price of approximately $20.1 million consisted of $12.0
million cash and 109,091 shares of the Company's Common Stock with an estimated
fair value of approximately $8.0 million and other acquisition related expenses
of approximately $100,000, consisting primarily of payments for legal and other
professional fees. Of the total purchase price, approximately $500,000 was
allocated to Property and equipment, and the remainder was allocated to
intangible assets, including customer list ($2.1 million), assembled workforce
($400,000) and goodwill ($17.1 million). The acquired intangible assets will be
amortized over their estimated useful lives of two to three years.

  The unaudited pro forma condensed consolidated balance sheet gives effect to
this acquisition as if it had occurred on March 31, 1999, by consolidating the
balance sheet of FABRIK Communications, Inc. with the balance sheet of Critical
Path, Inc. at March 31, 1999.

  The unaudited pro forma condensed consolidated statement of operations gives
effect to this acquisition as if it had occurred on January 1, 1998, by
consolidating the results of operations of FABRIK Communications, Inc. for the
year ended September 30, 1998 and the three months ended December 31, 1998,
with the results of operations of Critical Path, Inc. for the year ended
December 31, 1998 and the three months ended March 31, 1999.

  The unaudited pro forma condensed consolidated statement of operations is not
necessarily indicative of the operating results that would have been achieved
had the transactions been in effect as of the beginning of the periods
presented and should not be construed as being representative of future
operating results.

  The historical financial statements of the Company and FABRIK Communications,
Inc. are included elsewhere in this Prospectus and the unaudited proforma
condensed consolidated financial information presented herein should be read in
conjunction with those financial statements and related notes.

  The following adjustments were applied to the Company's historical financial
statements and those of FABRIK Communications, Inc. to arrive at the pro forma
condensed consolidated financial information. The pro forma adjustments are
preliminary and based upon Company management's estimates and a preliminary
valuation of the intangible assets acquired.

    (a) Reflects adjustments to eliminate assets, liabilities and equity that
  were not acquired by the Company.

    (b) The allocation of the purchase price, assuming the acquisition
  occurred on March 31, 1999, for pro forma purposes, is as follows:

</TABLE>

    (c) To record amortization of: acquired customer list totaling $2.1
  million over the estimated period of benefit of three years, assembled
  workforce totaling $400,000 over the estimated period of benefit of two
  years, and goodwill totaling $17.1 million over the estimated period of
  benefit of three years.

    (d) Reflects the adjustment to reduce interest income for lower cash
  balances as a result of the elimination of the FABRIK cash balance which is
  not being acquired by the Company, and the reduction in cash balances due
  to the $12 million paid on acquisition.

    (e) Pro forma basic net loss per share for the year ended December 31,
  1998 and the three months ended March 31, 1999 is computed using the
  weighted average number of common shares outstanding, including the pro
  forma effects of the conversion of the Company's Series A and Series B
  Convertible Preferred Stock into shares of the Company's Common Stock
  effective upon the closing of the initial public offering as if such
  conversion occurred on January 1, 1998, or at date of original issuance, if
  later. Pro forma diluted net loss per share is computed by dividing the net
  loss for the period by the weighted average number of common and potential
  common shares outstanding during the period if their effect is dilutive.
  Potential common shares comprise restricted Common Stock and incremental
  common and preferred shares issuable upon the exercise of stock options and
  warrants and upon conversion of Series A and B Convertible Preferred Stock.
  At December 31, 1998 and March 31, 1999, 28,607,997 and 16,024,637
  potential common shares respectively, are excluded from the determination
  of diluted net loss per share as the effect of such shares on a weighted
  average basis is anti-dilutive. Differences between historical weighted
  average shares outstanding and pro forma weighted average shares
  outstanding used to compute net loss per share result from the inclusion of
  shares issued in conjunction with the acquisition as if such shares were
  outstanding from January 1, 1998 and from the conversion of the Company's
  Series A and Series B Convertible Preferred Stock effective upon the close
  of the initial public offering.

FABRIK Communications, Inc.

  We have audited the accompanying consolidated balance sheets of FABRIK

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

  In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of FABRIK

1. The Company and Liquidity

  FABRIK Communications, Inc. (the "Company" or "Fabrik") provides messaging
services to the expanding electronic mail ("e-mail") market principally in the
United States. Fabrik provides users of local area network ("LAN") e-mail
systems a universal bridge to e-mail users outside their network, including
those on the Internet and all other wide area network ("WAN") e-mail services.

  Through fiscal 1998, Fabrik incurred cumulative net losses of $13,223,680,
including a net loss of $2,220,170 in 1998. During fiscal 1997 and 1998, Fabrik
used $6,042,500 and $1,469,110, respectively, of cash to finance its growth and
related operating activities. In fiscal 1999, Fabrik expects to incur
additional losses and will use additional cash to fund its operating
activities. In fiscal 1999, Fabrik's operating plan contemplates reducing and
then aligning its cost structure with expected revenue streams and eliminating
activities that are not clearly aligned with the Fabrik's near and longer term
strategies. Fabrik's financial plan contemplates obtaining additional third
party financing. However, there can be no assurance that such financing will be
available on terms acceptable to Fabrik, if at all. Should Fabrik be required
to delay or reduce expenditures, it may not be able to expand its suite of
services and may have to reevaluate its operating plans.

Basis of Presentation

  The consolidated financial statements include the accounts of Fabrik and its
wholly owned subsidiary. All significant intercompany transactions and balances
have been eliminated in consolidation.

  On May 26, 1999, Fabrik sold certain assets and customer relationships
related to its connect business to Critical Path, Inc. for consideration of
$12,000,000 in cash and 109,091 shares of Critical Path, Inc.'s common stock
valued at approximately $8,000,000. The accompanying consolidated financial
statements have been prepared on the Fabrik's historical cost basis and do not
reflect any adjustments resulting from the acquisition.

2. Summary of Significant Accounting Policies

  The following is a summary of Fabrik's significant accounting policies used
in the preparation of the accompanying consolidated financial statements.

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 financial statements and accompanying
notes and the reported amounts of revenue and expenses during the reporting
period. Actual results may differ materially from those estimates.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
  (Information for the Six Months ended March 31, 1998 and 1999 is Unaudited)


Interim Financial Information

  The interim financial information as of March 31, 1999 and for the six months
ended March 31, 1998 and 1999 is unaudited but includes all adjustments,
consisting only of normal recurring adjustments, that Fabrik considers
necessary for a fair presentation of its consolidated financial position at
such date and its consolidated results of operations and cash flows for those
periods. Operating results for the six months ended March 31, 1999 are not
necessarily indicative of results that may be expected for any future periods.

Cash and Cash Equivalents

  Fabrik considers all highly liquid investments purchased with original
maturities of three months or less to be cash equivalents.

Concentrations of Credit Risk and Credit Evaluations

  Financial instruments which subject Fabrik to concentrations of credit risk
consist primarily of cash and trade accounts receivable. Fabrik maintains its
cash and cash equivalents in a domestic financial institution with a high
credit standing. Fabrik conducts business principally with companies in various
industries throughout the United States. Fabrik performs ongoing credit
evaluations of its corporate customers and generally does not require
collateral. Reserves are maintained for potential credit losses and such
reserves to date have been within management's expectations.

Property and Equipment

  Property and equipment are stated at cost and are depreciated using the
straight-line method over the estimated useful lives of the related assets of
three years. Assets under capital leases and leasehold improvements are
amortized using the straight-line method over the lesser of the estimated
useful lives or the remaining lease terms, generally three years.

Income Taxes

  Fabrik accounts for income taxes in accordance with Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" ("FAS 109"), which
requires the use of the liability method in accounting for income taxes. Under
FAS 109, deferred tax assets and liabilities are measured based on differences
between the financial reporting and tax bases of assets and liabilities using
enacted tax rates and laws that are expected to be in effect when the
differences are expected to reverse.

Accounting for Stock-Based Compensation

  Fabrik accounts for employee stock options in accordance with Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees"
("APB 25") and has adopted the "disclosure only" alternative described in
Statement of Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("SFAS 123"). The effect of applying the fair value method of
SFAS 123 to Fabrik's stock options results in net losses that are not
materially different from the amounts reported.

  (Information for the Six Months ended March 31, 1998 and 1999 is Unaudited)


Revenue Recognition

  Fabrik provides messaging services for the e-mail market. These services
provide users of LAN e-mail systems a universal bridge to e-mail users outside
their network. Fabrik charges users monthly for certain e-mail transactions in
addition to a monthly service fee. Fabrik recognizes revenues as such services
are provided.

Research and Development

  Research and development costs are charged to operations as incurred.

Computation of Net Loss Per Share

  Fabrik adopted Financial Accounting Standards Board Statement No. 128,
"Earnings Per Share," ("FAS 128") during the year ended September 30, 1997. FAS
128 replaced the calculation of primary and fully diluted net loss per share
with basic and diluted net loss per share. In accordance with FAS 128, basic
net income (loss) per share excludes dilutive common stock equivalents and is
calculated as net income (loss) divided by the weighted average number of
common shares outstanding. Diluted net income (loss) per share is computed
using the weighted average number of common shares outstanding and dilutive
common stock equivalents outstanding during the period. Common equivalent
shares from stock options and warrants (using the treasury stock method) are
excluded from the calculation of net loss per share as their effect is anti-
dilutive.

Impact of Recently Issued Accounting Standards

  In June 1997, the Financial Accounting Standards Board issued Statement No.
130, "Reporting Comprehensive Income" ("FAS 130"). Fabrik is required to adopt
this statement in fiscal year 1999. FAS 130 establishes new standards for
reporting and displaying comprehensive income and its components. Adoption of
this statement had no material impact on Fabrik's consolidated financial
position, results of operations or cash flows.

  Additionally, the Financial Accounting Standards Board issued Financial
Accounting Standards Board Statement No. 131, "Disclosure about Segments of an
Enterprise and Related Information" which establishes standards for the way
public business enterprises report information in annual statements and interim
financial reports regarding operating segments, products and services,
geographic areas, and major customers. Fabrik has determined that it operates
in one segment.

Reclassifications

  Certain prior year balances have been reclassified to conform to the current
year presentation.

3. Note Receivable from Officer

  In February 1996, Fabrik loaned an officer a total of $30,000 in return for a
promissory note. In February 1998, the note was amended to $33,192 to include
the original amount of the note plus accrued interest. The principal on the
note, which is unsecured, is due and payable in February 2000. Interest is
payable annually on the note in arrears at a rate of 5.32% per annum.

6. Related Party Transactions

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

1997 and 1998, purchases of services from this supplier amounted to $330,525
and $78,887, respectively. At September 30, 1997 and 1998, amounts due to this
supplier were $102,942 and $2,332, respectively.

7. Bank Line of Credit

  In June 1998, Fabrik entered into a revolving line of credit agreement with a
bank which provides for a line of credit of up to $2 million. Borrowings under
the line of credit bear interest at the bank's prime rate plus .5% (8.3% at
September 30, 1998). Interest payments are due monthly. Total borrowings are
limited to the lesser of $2 million or 80% of eligible accounts receivable and
are secured by Fabrik's assets. At September 30, 1998, there were no
outstanding borrowings on the line of credit. The line of credit agreement
expires on June 15, 1999, at which time all amounts due and payable under this
agreement must be paid. Of the revolving line of credit, $200,000 is restricted
for purposes of meeting deposit requirements of Fabrik's payroll processor.

  Among other provisions, the bank line of credit requires Fabrik to maintain
certain minimum financial ratios and profitability/maximum loss provisions.
Fabrik was not in compliance with the maximum loss provision for the fourth
quarter of the year ended September 30, 1998. Fabrik subsequently obtained a
waiver from the bank for this violation.

  Under Fabrik's Articles of Incorporation, preferred stock is issuable in
series and the Board of Directors is authorized to determine the rights,
preferences and terms of each series.

  Dividends

  The holders of shares of preferred stock, in preference to the holders of any
other stock of Fabrik, are entitled to receive, when and as declared by the
Board of Directors, but only out of funds that are legally available, dividends
at the rate of eight percent (8%) of the "Original Issue Price" per annum on
each outstanding share of preferred stock (as adjusted for any stock dividends,
combinations or splits with respect to such shares). The Original Issue Price
of the Series A,

Series B, Series C, Series D and Series E preferred stock is $1.00, $1.20,
$.67, $.76, and $1.20, respectively.

  Conversion

  Each share of preferred stock, at the option of the holder, is convertible
into the number of fully paid and nonassessable shares of common stock at the
conversion rate. The conversion rate per share of the Series A, Series B,
Series C, Series D and Series E preferred stock is 5:1, 5:1, 1:1, 1:1, and 1:1,
respectively. The conversion rates are subject to adjustment from time to time.
The number of shares of common stock into which a share of a series of
preferred stock is convertible is referred to as the conversion rate of such
series.

  Each share of preferred stock shall automatically be converted into shares of
common stock, based on the then-effective conversion price, at any time upon
the affirmative vote of the holders of at least 66-2/3% of the outstanding
shares of the Preferred Series, or immediately upon the closing of a firmly
underwritten public offering pursuant to an effective registration statement
under the Securities Act of 1933, as amended, covering the offer and sale of
common stock for the account of Fabrik in which (i) the per share price is at
least $5.00 (as adjusted for stock splits, recapitalizations and the like), and
(ii) the gross cash proceeds to Fabrik (before underwriting discounts,
commissions and fees) are at least $10,000,000.

  Redemption

  The holders of at least sixty-six and two-thirds percent (66-2/3%) of the
then outstanding preferred stock, voting as a separate class, may, by notice
delivered on or before March 1, 2001, require Fabrik to redeem the preferred
stock in four equal annual installments beginning on August 1, 2001 and ending
on August 1, 2004 (each a "Redemption Date"). Fabrik shall effect such
redemptions on the applicable Redemption Date by paying in cash in exchange for
the shares of preferred stock to be redeemed a sum equal to the Original Issue
Price per share of preferred stock (as adjusted for any stock dividends,
combinations or splits) plus declared and unpaid dividends with respect to such
shares. The number of shares of preferred stock that Fabrik shall be required
to redeem on any one redemption date is equal to the amount determined by
dividing the number of shares outstanding immediately prior to the Redemption
Date by the number of remaining Redemption Dates (including the Redemption Date
to which such calculation applies). Shares subject to redemption are to be
redeemed from each holder of preferred stock on a pro rata basis.

  If Fabrik does not have sufficient funds legally available to redeem all
shares to be redeemed at the Redemption Date (including, if applicable, those
to be redeemed at the option of Fabrik), then Fabrik shall redeem such shares
pro rata (based on the portion of the aggregate Redemption Price payable to
them) to the extent possible and shall redeem the remaining shares to be
redeemed as soon as sufficient funds are legally available.

  Liquidation

  In the event of any liquidation, dissolution or winding up of Fabrik, whether
voluntary or involuntary, the holders of preferred stock are entitled to
receive, prior and in preference to any

distribution of any of the assets of Fabrik to the holders of common stock by
reason of their ownership, an amount per share equal to the sum of Original
Issue Price, plus any declared but unpaid dividends on such share. After
payment of the full liquidation preference of the preferred stockholders, any
remaining assets of Fabrik legally available are to be distributed ratably to
the holders of the common stock and preferred stock on an as-if-converted to
common stock basis until such time as the holders of preferred stock and common
stock have received a total liquidation amount of one hundred million dollars
($100,000,000). The remaining assets of Fabrik legally available for
distribution, if any, are to be distributed ratably to the holders of common
stock.

  If, upon the occurrence of a liquidation event, the assets and funds
distributed among the holders of the preferred stock are insufficient to permit
the payment to such holders of the full preferential amount, then the entire
assets and funds of Fabrik legally available for distribution are to be
distributed ratably among the holders of the preferred stock, in proportion to
the preferential amount each such holder is otherwise entitled to received.

  Voting

  The holder of each share of preferred stock is entitled to the number of
votes equal to the number of shares of common stock into which each share of
preferred stock could be converted immediately after the close of business on
the record date for the vote or consent of shareholders, except as otherwise
required by law, and has voting rights and powers equal to the voting rights
and powers of the common stock.

Warrants

  In connection with the capital lease facility, Fabrik has issued four
warrants. The first is a warrant issued in October 1994 to purchase 48,750
shares of Series A redeemable preferred stock at $1.00 per share expiring on
December 31, 2000 (convertible into 243,750 common shares). The second warrant
issued in October 1995 allows the lessor to purchase 73,294 shares of Series C
redeemable preferred stock at $0.67 per share, expiring on December 31, 2001.
Fabrik deemed the fair value of these warrants to be immaterial at the date of
issuance. The third warrant issued in November 1996 allows the lessor to
purchase 72,368 shares of Series D redeemable preferred stock at $0.76 per
share, expiring on September 30, 2002. Fabrik valued the warrant at $18,095.
The fourth warrant issued in April 1997 allows the lessor to purchase 95,000
shares of Series D redeemable preferred stock at $0.76 per share expiring on
December 31, 2002. Fabrik valued this warrant at $23,750.

  In association with a July 1996 promissory note, Fabrik issued warrants in
August 1997 to purchase an aggregate of 197,368 shares of Series D preferred
stock at $0.76 per share. Fabrik valued the warrants at $19,735. The warrants
were issued to certain investors involved in the bridge financing. These
warrants expire December 31, 1999. No new warrants were issued during the year
ended September 30, 1998.

Options Issued to Consultants

  Fabrik granted options to purchase 49,500 shares of common stock to
consultants at exercise prices ranging from $.08 to $.30 throughout fiscal
1997. These options were granted in exchange for consulting services performed.
Fabrik valued these options using the fair value of the services performed
which amounted to $73,923. This amount was recorded as consulting expense and
additional paid-in capital in the year ended September 30, 1997.

Equity Incentive Plan

  Under the 1995 Equity Incentive Plan (the "Plan"), the Board of Directors may
issue incentive stock options, nonstatutory stock options and stock bonuses to
employees of Fabrik. As of September 30, 1998, Fabrik has reserved 5,920,000
shares of common stock for issuance under the Plan. The Board of Directors
determines to whom options and bonuses will be granted, the number of shares,
the term and the exercise price (which cannot be less than the fair market
value at the date of grant, or 85% of fair market value for nonstatutory stock
options). Options granted under the Plan to date generally become exercisable
ratably over a four-year period with a one-year anniversary cliff in the first
year of the option term.

  Activity under the Plan is as follows:

years ended September 30, 1997 and 1998 and the six months ended March 31, 1999
was $.03, $.08 and $0.09 per share, respectively.

9. Income Taxes

  The Company did not provide any current or deferred federal, state or foreign
income tax provision or benefit for the periods presented because it has
experienced operating losses since inception.

  As of September 30, 1998, the Company had federal and state net operating
loss carryforwards of approximately $9,500,000 and $6,400,000, respectively.
The federal and state net operating loss carryforwards will expire in the years
ending 2002 through 2013, if not utilized. Utilization of the net operating
loss carryforwards may be subject to a substantial annual limitation due to the
ownership change limitations provided by the Internal Revenue Code of 1986 and
similar state provisions. The annual limitation may result in the expiration of
the net operating losses before utilization.

  Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components
of the Company's deferred tax assets are as follows:

  The Company has provided a full valuation allowance on the deferred tax
assets due to uncertainty regarding their realizability. The valuation
allowance increased by $2,795,000 and $800,000 during the years ended September
30, 1997 and 1998, respectively.

10. Retirement Plan

  Fabrik has established the 401(k) Savings and Retirement Plan (the "Plan")
under Section 401(k) of the Internal Revenue Code covering substantially all of
its employees. Under the Plan, participating employees may defer a portion of
their pretax earnings up to the Internal Revenue Service annual contribution
limit. Fabrik does not make contributions to the Plan.

11. Year 2000 Issue (Unaudited)

  The Year 2000 issue relates to the use by many existing computer programs of
only two digits to identify a year in the date field. If not corrected, many
computer applications could fail or create erroneous results by or at the year
2000. Fabrik recognizes the need to ensure that the potential Year 2000
software failures will not adversely impact its operations. Fabrik believes
that Year 2000 problems will not have a material adverse effect on its results
of operations or financial position.

  Fabrik is in the process of determining if the current versions of Fabrik's
internally developed and purchased software are Year 2000 compliant.
Additionally, Fabrik is in the process of completing its Year 2000 assessment
of internal systems and applications. Fabrik is also in the process of
determining if all of its hardware systems are Year 2000 compliant. Fabrik
expects some changes to its systems will be necessary to reach compliance and
plans to complete the Year 2000 conversion of such systems by March 1999. To
date, Year 2000 costs have been minimal and Fabrik believes that future costs
will be immaterial. However, there can be no assurances that Fabrik will not
experience serious unanticipated negative consequences and/or material costs
caused by undetected errors or defects in the technology used in its internal
systems.

  Fabrik has also initiated communications with third parties on which it is
dependent for essential software and services (including services necessary for
Fabrik to perform its own services) to determine how they are addressing Year
2000 issues and to evaluate any impact on Fabrik's operations. Although Fabrik
intends to work with these third parties to resolve Year 2000 compliance
issues, the lack of resolution of Year 2000 issues by these parties could have
a material adverse effect on Fabrik's future business operations, financial
condition and results of operations. At this time, Fabrik cannot quantify the
potential impact of third-party Year 2000 issues; nor has it developed
contingency plans for the possibility that one or more of such third parties
may experience a significant disruption due to Year 2000 issues.

  The year 2000 readiness of the general infrastructure necessary to support
its operations is difficult to assess. For instance, Fabrik depends on the
integrity and stability of the Internet to provide its services. Fabrik also
depends on the year 2000 compliance of the computer systems and financial
services used by consumers. Thus, the infrastructure necessary to support its
operations consists of a network of computers and telecommunications systems
located throughout the world and operated by numerous unrelated entities and
individuals, none of which has the ability to control

                                      F-41

or manage the potential year 2000 issues that may impact the entire
infrastructure. Fabrik's ability to assess the reliability of this
infrastructure is limited and relies solely on generally available news
reports, surveys and comparable industry data. Based on these sources, Fabrik
believes most entities and individuals that rely significantly on the Internet
are carefully reviewing and attempting to remediate issues relating to year
2000 compliance, but it is not possible to predict whether these efforts will
be successful in reducing or eliminating the potential negative impact of year
2000 issues. A significant disruption in the ability of consumers to reliably
access the Internet or portions of it would have an adverse effect on demand
for Fabrik's services and would have a material adverse effect on Fabrik.

  At this time, Fabrik has not yet developed a contingency plan to address
situations that may result if Fabrik or its vendors are unable to achieve year
2000 compliance because Fabrik currently does not believe that such a plan is
necessary. The cost of developing and implementing such a plan, if necessary,
could be material. Any failure of its material systems, Fabrik's vendors'
material systems or the Internet to be year 2000 compliant could have material
adverse consequences for Fabrik.

12. Subsequent Events

  In October 1998, Fabrik entered into a services agreement with a third-party
service provider under which the service provider will provide Fabrik with
telecommunications services. The term of the agreement is for three years
beginning November 1998 and will require payments by Fabrik totaling $234,654
over the three-year term.

  In October 1998, Fabrik granted a new officer of Fabrik options to purchase
1.6 million shares of common stock, or approximately 5% of the total
outstanding shares of Fabrik. These options were granted at an exercise price
of $.45 per share, the fair market value of underlying common stock on the date
of grant, and will vest over a four-year period.

  In November 1998, Fabrik entered into an equipment financing lease agreement
with a financial services company. The agreement provides Fabrik with a lease
line for up to $2,500,000 for the purchase of computer equipment and software.
The term of the agreement is 42 months. In November 1998, Fabrik drew down
$203,190 under the agreement for the purchase of computer equipment. Under the
agreement, the financial services company has the right to purchase preferred
stock in all of Fabrik's future private or public offerings in amounts of not
less than $10,000 and not more than $500,000 at the fair market value at the
time of such an offering.
