COMPANY OVERVIEW

     We are a leading provider of complete end-to-end Internet messaging and
collaboration solutions for Internet service providers or ISPs,
telecommunications providers, web hosting companies, web portals and
corporations. We provide services and products, both on a hosted and licensed
basis, that enable our customers to provide feature-rich email, messaging,
collaboration and directory services to their customers and employees. Our
allsourcing strategy provides flexibility to our customers by giving them the
option of using our Critical Path hosted services, licensing our software to run
on their own hardware, or selecting a combination of both. Our solutions enable
customers to improve messaging performance, reduce the cost of providing
messaging services and focus on other aspects of their businesses.

     We have over 2,000 customers and reach over 55 million end-users and 20
million wireless devices through our customer relationships. Our customers
include leading Internet companies such as AltaVista, E*TRADE, ICQ (a subsidiary
of America Online) and Netscape as well traditional enterprises such as General
Electric, Proctor & Gamble and Promus Hotel Corporation. International customers
include Avantel, British Telecommunications, Cable and Wireless, Eircell, Global
Telesystems Group, Korea Telecom, Sina and Starmedia. In addition, we have a
number of relationships to expand our distribution channels with companies such
as British Telecommunications, Compuserve (a subsidiary of American Online),
France Telecom, MCI Worldcom, Mitsui, Network Solutions, NTT, Qwest
Communications, Sprint, US West and VeriSign.

     There are a number of trends that are driving demand for messaging and
collaboration solutions. Email has broadened from a simple messaging tool to a
widely accepted form of communication. At the same time, the complexity of
individual messages and the scale of the supporting applications and hardware
are growing dramatically, forcing businesses to dedicate significant resources
to the operation and maintenance of their messaging systems. In addition,
customers are increasingly demanding reliable and scalable service and enhanced
product offerings. Accordingly, it is important for businesses to adopt more
effective approaches to the management of their messaging and collaboration
needs.

     Our end-to-end solutions complement our core email hosting services and
support the growing demands of our rapidly expanding worldwide customer base. We
provide a full spectrum of messaging and collaboration solutions, such as
calendaring, document archival, Internet fax, secure document delivery, resource
management and wireless access. Our solutions are supported by our global
infrastructure with data centers located worldwide connected to key Internet
exchange points.

     In recent months, we have significantly expanded our range of products and
services and the delivery options we offer our domestic and international
customers. Our extended messaging solutions include support for wireless devices
through relationships with American Mobile Satellite, Arch Communications,
Cellnet, VAST and other international wireless carriers; integrated calendaring
and resource scheduling; bi-directional

                                        3
<PAGE>   4

fax to email; and security measures and directory services. In addition to our
outsourced hosted services, we now offer midsourcing, where a customer selects
which products and services to outsource to augment their existing messaging
infrastructure, and insourcing, where a customer installs and maintains our
software.

     Our objective is to be the premier provider of comprehensive, advanced
messaging and collaboration services. We plan to attain this goal by:

     - Extending our technology leadership in messaging applications;

     - Acquiring new businesses and technologies that could expand our product
       and service offerings;

     - Developing and leveraging strategic relationships;

     - Increasing our sales and marketing efforts;

     - Offering value-added products and services such as secure guaranteed
       delivery, collaborative messaging and calendaring; and

     - Expanding our international presence.

RECENT DEVELOPMENTS

     To achieve our objectives, we have announced several recent acquisitions
and strategic relationships that have expanded our range of products and
customers and broadened our global reach, including:

     docSpace Acquisition. On March 8, 2000, we acquired The docSpace Company, a
provider of Web-based enhanced delivery services. The total purchase price was
valued at approximately $300 million in our common stock and cash. docSpace
provides services for businesses to send, store and collaborate on their
important files securely via encryption technologies from anywhere in the world.

     ISOCOR Acquisition. On January 19, 2000, we acquired ISOCOR for common
stock valued at approximately $274 million. The acquisition enables us to
provide directory and meta-directory services to connect disparate database
applications and to overcome incompatibilities across the corporate enterprise.
Customers such as IBM, Proctor & Gamble and Netscape use our directory products
to connect databases, email directories, online ordering systems and proprietary
groupware systems, enabling the organizations to provide accurate, up-to-date
information to employees, customers and trading partners.

     FaxNet Acquisition. On December 6, 1999, we acquired FaxNet Corporation, a
provider of Internet fax and messaging solutions and a leading outsource
supplier of enhanced fax and integrated messaging solutions. The total purchase
price was approximately $199 million, and consisted of shares of our common
stock and cash. FaxNet has attracted customers such as Ameritech, Ariba, Bell
Atlantic, Bell South, MediaOne Group, Qwest, Time Warner's Road Runner and US
West, by providing branded, private label, turnkey solutions.

     RemarQ Acquisition. On February 7, 2000, we announced the signing of a
definitive agreement to acquire RemarQ Communities Inc., a provider of
customized, collaborative message boards for business use. The total purchase
price will be approximately $267 million in our common stock. The acquisition,
which is expected to close on or before March 31, 2000, will enable us to offer
products that allow customers to hold online discussions over extranets,
intranets, or the Internet. Message boards are an ideal environment for
knowledge exchange and team collaboration.

     Critical Path Pacific Alliance. We have signed a memorandum of
understanding to enter into a joint venture with Mitsui and Co, Ltd. and NTT
Communications Corp. to bring our messaging solutions to Japan. The joint
venture will leverage our technology, infrastructure and services; Mitsui's
extensive partnerships in Japan and throughout Asia; and NTT's Data Centers and
technical backbone to deliver advanced Internet messaging services to the
Japanese business and wireless markets.

INDUSTRY BACKGROUND

     Growth of Messaging.  Email has broadened from a simple personal messaging
tool to a strategic business tool. According to International Data Corporation,
or IDC, there were approximately 315 million electronic mailboxes worldwide as
of July 1999, and this number is expected to grow to over 750 million electronic
mailboxes by 2005. IDC estimates that 1.4 trillion emails are sent annually.
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.

     Growth of Wireless Messaging. The number of devices on which people can
access Internet messaging is growing sharply. Many wireless phones, pagers,
Personal Digital Assistants and other devices now have access to email and other
forms of Internet messaging. IDC forecasts that there will be approximately one
billion wireless handsets in 2003, roughly double the number of Internet-enabled
computers expected to be in use. Nokia and Ericsson both assert that all new
wireless phones manufactured in 2001 and later will provide Internet access.

     Current Trends in Messaging. As the importance of messaging grows,
customers increasingly expect their messaging service to meet the same standards
of carrier-class reliability and availability that consumers have traditionally
received from their telephone service providers. For example, customers expect
reliability from their messaging service similar to the dial tone they hear when
they pick up the telephone. Similarly, customers want access to their messages
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
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,
telecommunications providers, 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 telecommunications
providers 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 and
functionality. The use of enhanced messaging services such as graphics,
multimedia elements, fax attachments and secure delivery is becoming more common
and requires greater functionality on the part of the messaging service to
process and deliver these messages. As organizations and the numbers of users
grow, the ability to accommodate thousands, or millions, of additional mailboxes
in a single domain requires substantial investments 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

                                        5
<PAGE>   6

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.

     Another trend in messaging is the growing diversity and importance of
sourcing options. Gartner Group forecasts that 65% of corporations will
outsource some or all of their messaging by 2001. The Radicatti Group estimates
the market size for outsourced messaging will exceed $6 billion in 2003.
Outsourced messaging services require specialized technology that can handle
additional functionality, such as directory synchronization.

THE CRITICAL PATH SOLUTION

     Critical Path delivers advanced messaging and collaboration solutions to
ISPs, telecommunications providers, web hosting companies, web portals and
corporations, giving them the ability to provide feature-rich email, messaging
and directory services to their customers and employees. Critical Path's
products and services are designed to provide the following key benefits:

     Focus. Critical Path's customers benefit from the company's depth of
expertise in many areas of advanced Internet messaging. Messaging has become the
number one business communication tool, making it mission-critical for many
companies. Yet messaging technology and the demands of users have become more
complex with the advent of integrated email, fax, voice and calendaring.
Critical Path delivers access to industry-leading solutions regardless of
whether a customer chooses to outsource their messaging needs to Critical Path
or license its software to manage their messaging needs in-house.

     Lower total cost of ownership. Critical Path's outsourcing 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
messaging services. Critical Path's service is designed to reduce customers'
administrative burden by eliminating the cycle of purchasing, installing,
testing, debugging and deploying messaging systems. The software is maintained
at Critical Path's facilities, not at customers' facilities, and Critical Path
employs 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,
Critical Path's hosted service provides customers with cost savings over
in-house messaging solutions through economies of scale.

     Scalability; reliability. Critical Path's hosted and licensed systems are
designed to facilitate scalability and reliability. While existing competitive
email software solutions can scale to support millions of users at a single
domain ([email protected]), Critical Path has designed its hosted architecture to
support its 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. Critical
Path's hardware and software infrastructure consists of multiple servers running
software in a manner that balances the use of the servers without dedicating any
server to a specific domain or mailbox. This infrastructure allows multiple
domain hosting while reducing the amount of required equipment and capacity.
Critical Path has created a global network strategy to provide the type of
continuous service that individuals have come to expect from their telephone and
other utility service providers. Critical Path provides its customers improved
performance through its multiple peering relationships, agreements with
companies with existing peering relationships and the purchase of additional
access to telecommunication paths from national Internet access providers.
Critical Path maintains six data centers in the United States and two data
centers in Europe. Critical Path plans to open an additional data center in
Asia.

                                        6

     Leading-edge technology. Critical Path provides customers with access to
advanced technologies through both outsourced, midsourced and insourced delivery
mechanisms. Critical Path's outsourced messaging solutions eliminate the need
for customers and partners to maintain a core competency in advanced messaging
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. Critical Path's products and services
include webmail, POP3, IMAP4 and hosted groupware, fax and directory systems,
which enable customers to choose messaging solutions that meet their needs.
Critical Path also delivers wireless access, integrated calendars, security and
other complex features. Critical Path's technological capabilities enable it to
quickly implement competitive new technologies for its customers and end-users,
reducing their time to market for leading technologies.

     Critical Path's server software has been designed to provide high
performance while reducing hardware requirements. This has been achieved through
a design methodology that eliminates the overhead of protocol layering and
reduces the number of computer instructions required to perform common
operations. The design also reduces the risk that messages will be lost or will
not be duplicated in the event of external system breakdowns, such as loss of
power or hardware failures. This promotes high reliability of the electronic
information exchange and allows Internet service providers to utilize the
software to offer email services to their customers.

     Anytime, anywhere accessibility. Critical Path has designed its services to
allow easy access by customers and end-users. Designed and built on open
Internet-based standards, Critical Path's services are compatible with leading
desktop software such as Microsoft Outlook, Netscape Messenger and Qualcomm's
Eudora. In addition, it has developed a web-based email interface that is
compatible with leading web browsers, including Microsoft Internet Explorer and
Netscape Navigator. Critical Path's services are designed to allow
administrators and end-users to access their email system anywhere at any time,
providing end-users with the means to send and receive messages to and from
mobile phones, pagers and other wireless devices. Critical Path has recently
entered into relationships with wireless service providers to deliver email and
messaging access to digital wireless phones and pagers.

     Enhanced security. Critical Path has created a custom firewall solution to
enhance network and data center security for its hosted services. Using a
combination of licensed software technology, internally developed software and
sophisticated third-party hardware, Critical Path reduces the potential for
network breaches. Critical Path has network and data center surveillance 24
hours a day, seven days a week to identify and curtail potential security
breaches. In addition, Critical Path provides secure document delivery services
and digital certificates for greater messaging security. For its hosted
services, Critical Path also provides a secure software interface to mailbox
account provisioning that allows customers to integrate their existing
functionality with Critical Path's email system. This enables customers to add
and delete accounts and functionality either at the domain level or at the
individual end-user level over an encrypted connection.

     Branding; customer control. Critical Path's messaging service solution
enables its customers to maintain brand control by allowing graphical user
interfaces to be branded uniquely for each customer. Critical Path is, and will
continue to be, the brand behind the brand. Critical Path's fully customized
web-based "brandable" email product interface includes customer logos and
preserves the existing "look and feel" of the customers' brands. Critical Path's
web-based, brandable, mail administration center is designed to give customers
control of their mail accounts via a secure web-based interface.

STRATEGY

     Critical Path's objective is to be the premier provider of comprehensive,
advanced Internet messaging and collaborative services. Critical Path plans to
attain this goal by pursuing the following key strategies:

     Extend Technology Leadership in Messaging Applications. Critical Path
intends to continue expanding its ability to deliver industry-leading
functionality in all areas of electronic messaging. Building upon its
Internet-based messaging architecture, Critical Path plans to continue to
deliver industry-leading functionality, capabilities and new applications that
will extend the core functionality of email and Internet messaging, support
wireless devices, and provide secure delivery and cost-effective resource

<PAGE>   8

development team regularly meets with customers and participates in research
projects with leading industry groups and analysts to anticipate future customer
needs. Critical Path also participates in open standards organizations and
Internet technology leadership groups, such as the Internet Engineering Task
Force.

     Acquire New Businesses and Technologies. Critical Path evaluates
opportunities with respect to possible acquisitions of businesses or
technologies on an ongoing basis. Critical Path will continue to seek
acquisitions that will complement its current and planned business activities.
Critical Path has a dual strategy in pursuing acquisitions. First, Critical Path
plans to focus on target companies in its market with large numbers of customers
which will enable it to expand its customer base. Second, Critical Path will
evaluate companies that help it augment its service and product offerings for
customers. In addition, these value-added services and products may be used by
customers not using Critical Path's messaging service to enhance the
functionality of their messaging solutions.

     Develop and Leverage Strategic Relationships. Critical Path intends to
expand its marketing and distribution channels through strategic relationships
with key ISPs, telecommunications providers, web hosting companies, web portals
and corporations to increase quickly the number of its end-users. Critical
Path's strategic partners include British Telecommunications, Compuserve,
E*TRADE, France Telecom, ICQ (a subsidiary of America Online), MCI Worldcom,
Mitsui, Netscape, Network Solutions, NTT, Quest Communications, Sprint, US West
and VeriSign. Critical Path intends to further develop new and existing
strategic relationships to expand its distribution channels and to undertake
joint product development and marketing efforts, such as integrating its
messaging services into e-commerce applications.

     Increase Sales and Marketing Efforts. Critical Path intends to continue to
expand its sales and marketing activities while focusing on five target markets:
ISPs, telecommunications providers, web hosting companies, web portals and
corporations. In this expansion, Critical Path plans to target and hire seasoned
sales professionals with specific expertise and contacts within its focused
markets. Critical Path also intends to expand its indirect sales channel by
teaming with additional leading distributors, resellers and system integrators
with strong backgrounds and market presence. As of March 15, 2000, Critical Path
had 243 sales and marketing personnel.

     Offer Value-Added Services. Critical Path intends to continue to extend its
messaging services by offering additional value-added services. These services
are intended to extend Critical Path's relationships with current customers, to
attract new customers and to allow it to differentiate itself in the messaging
market. Critical Path believes that its messaging technology can continue to
form the foundation of a wide range of Internet messaging applications for which
it intends to provide solutions.

     Expand International Presence. In addition to expanding its U.S. presence,
Critical Path believes there is substantial opportunity for outsourcing
messaging services in non-U.S. markets. Critical Path intends to further develop
its worldwide sales offices, data centers and strategic relationships. Critical
Path currently has operations in Argentina, Brazil, Denmark, France, Germany,
Ireland, Italy, Switzerland and the United Kingdom. In addition, Critical Path

interfaces. For example, Critical Path has already developed web-based
application interfaces in 15 languages and dialects and has recently signed a
memorandum of understanding for a joint venture in Japan.

SERVICES AND PRODUCTS

     Critical Path offers its messaging solutions through both outsourced
services, where Critical Path hosts the software on its servers, and insourced
server software packages, where the customer licenses software to run on its own
servers. In addition, a customer may choose to midsource, a combination of
outsourced and insourced solutions. Critical Path believes its combination of
outsourcing and insourcing options delivers unique value to customers by
providing continuity of relationship and technology across a variety of
offerings and user populations.

enhancements, upgrades and new standard features. Pricing for email and other
hosted messaging services generally is based on a per mailbox, per month charge
that varies depending on functionality and volume. Web portal market pricing
also may include a share of revenue generated by advertising on the web-based
email interface. Critical Path offers a flexible suite of messaging services.
The standard email service offering includes its basic services such as POP3 and
webmail as part of the monthly mailbox fee. The premium services are optional
add-ons to the basic mailbox charge and are offered for an additional fee.

     Message Server Products. N-PLEX, Critical Path's Internet server product,
provides robust message management, administrative control and secure message
transfer to the SMTP, POP3 and IMAP4 standards.

Security holes are greatly reduced by the proprietary design, and authenticated
login facilities have been added using encryption technology to prevent
unauthorized access to the mail systems.

     The N-PLEX Management Center manages Critical Path's insourced message
server products, providing the high level of service necessary for implementing
mission-critical electronic information exchange. The N-PLEX Management Center
performs remote management of components over TCP/IP, thereby allowing the
administrator to manage multiple sites simultaneously from a central management
station. The management facilities include remote configuration, routing
configuration, fault notification, performance monitoring, system management and
message tracking.

     Directory Products. As systems increase in size and complexity,
organizations increasingly need to implement a central repository for the
information required to communicate across systems. The Global Directory Server,
or GDS, Critical Path's directory product, is designed to store and disseminate
information on both a wide area and local area basis. This information may
include email addresses and cryptographic material for digital signatures and
message confidentiality that are used invisibly by client software, as well as
information that users may access directly, such as telephone numbers, fax
numbers, physical mail addresses and pictures. The directory allows efficient
and rapid updating of this information for use at diverse locations, reducing
errors and saving the time and personnel resources required to maintain and
distribute this data. This distributed application architecture allows system
managers to optimize the location of information so that information required
locally is on the local server, while users continue to have transparent access
to information on any other server in the network.

     MetaConnect, Critical Path's meta-directory product, is designed to unify
data for effective intranet and Internet use, enabling an organization to
provide employees, customers and trading partners accurate, updated information
from existing data sources. This product manages the connections to disparate
directories and applications databases and joins the information together in one
meta-directory, which can be centrally managed as a unified resource across the
enterprise. The product is designed to use most existing LDAP v3 directory
servers, including Microsoft Active Directory, Netscape Directory Server,
Novell's NDS and Critical Path Global Directory Server.

     Calendaring and Scheduling Server Products. Critical Path's EventCenter
calendaring solution is designed for enterprises and portals who need to
communicate many complex events and programs. Using a web browser, managers
create program calendars. Viewers can choose a rolled-up view of multiple
calendars, a single calendar view, or the details of a single event. EventCenter
creates a single source of program and event information for more-informed
planning and streamlined coordination.

     Critical Path's resource management solution, Reserve and Mobilize, help
customers reduce costs and increase efficiency through the improved utilization
of resources and workspace. Critical Path's solutions are typically used for
asset management and space utilization by large, Fortune 1000 companies, such as
Arthur Andersen, AT&T, IBM, KPMG, Pitney Bowes and State Farm Insurance. Reserve
automates the scheduling of shared corporate resources. Using a web browser and
corporate intranet, any authorized user can quickly and easily check on
availability and schedule a desired resource. Reserve Services standardizes and
automates the service request process throughout the enterprise. Using a web
browser and corporate intranet, users can place requests for services, which are
then delivered directly to the service provider. Mobilize automates the
reservation and coordination processes for shared workspaces. Using a web
browser and corporate intranet, incoming mobile workers can select and locate
their workspaces, route phone lines and arrange for needed equipment.

TARGET MARKETS

     Critical Path targets customers in the following distinct target markets:
ISPs, telecommunications providers, web hosting companies, web portals and
corporations.

     Internet Service Providers. ISPs are companies that provide access to the
Internet. Email and other messaging services have become an integral part of ISP
service offerings. ISPs provide service via dial-up and ISDN as well as
dedicated private-line hookups. Many ISPs offer free home-page hosting to
members at the

                                       13
<PAGE>   14

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 and small companies by providing a direct connection
from the companies' networks to the Internet.

     Telecommunications Providers. Telecommunications providers add advanced
Internet messaging solutions to their connectivity and data management offerings
to increase value and retain customers. Telecommunications providers desire both
a broad set of features and functionality as well as a selection of insourced,
outsourced and midsourced delivery mechanisms.

     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, web hosting companies are
increasingly offering web design, domain name registration service and messaging
services to their customers. Critical Path believes 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, search engines and
applications that 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
to draw large online audiences, encourage repeat visits, and keep users engaged.
Portals are accomplishing this by providing users with value-rich content and
services such as search engines, access to applications and services, free
individual homepages and email and other forms of advanced messaging.

     Corporations. Email and other messaging services have become a
mission-critical application for businesses. In addition, the ability to access
Internet-based email from outside the office has added to its appeal and utility
for corporations. A large percentage of the corporate market's email is supplied
internally by 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.

WIRELESS RELATIONSHIPS

     Critical Path's technology supports one-way and two-way messaging services
to up to 20 million wireless devices and is one of the only companies able to
provide end-users with the means to send and receive messages to and from mobile
phones, paging and other wireless devices. Critical Path has established
relationships with companies such as American Mobile Satellite, Arch
Communications, Debitel, FCR (France), Fiat (Italy), Meteor (Ireland), Mitsui
(Japan), Omnitel Pronto Italia (Italy), SwissCom (Switzerland), Tele2 (Sweden)
and TriGem (Korea). It is estimated that the number of world-wide wireless
subscribers will grow from just over 400 million subscribers in 1999 to 1
billion in 2003. Critical Path is aggressively targeting the wireless market
across all major segments including ISPs, portals carriers, wireless original
equipment manufacturers, or OEMs, and other cellular and paging companies.

STRATEGIC RELATIONSHIPS

     A key element of Critical Path's strategy is to expand its distribution
channels through strategic relationships with entities that are equity investors
or entities with which it has contractual reseller relationships. Critical Path
believes that these strategic relationships will enable it to expand its
distribution channels. The following are examples of Critical Path's existing
strategic relationships that it believes will position it to increase quickly
the number of electronic mailboxes it hosts.

     American Mobile Satellite. In February 2000, Critical Path formed a
marketing alliance with American Mobile Satellite enabling the two companies to
work together to promote a seamless wireless email solution to Critical Path's
customers. Using American Mobile's nationwide ARDIS(R) network and a wireless
handheld email device, Critical Path will enable its customers to provide their
end users with a two-way wireless extension of their desktop email. This allows
the end user to send and receive email from their desktop address, whether in
the office or on the road. In addition to a single address, users can decide how
often their email will be forwarded and, using filters, can selectively
designate which emails are forwarded.

                                       14
<PAGE>   15

     VAST. In September 1999, Critical Path formed a strategic relationship with
VAST. Through this relationship, VAST will provide Critical Path's carrier-class
Internet messaging solutions to wireless carriers and other businesses that wish
to extend their Internet-based services to wireless users. VAST works with
wireless carriers to provide access to value-added services like web-based email
and information services that can generate additional revenue for carriers.
Through VAST Gateway Services, wireless carriers and other companies can extend
these capabilities to wireless users at a low cost. Critical Path enables VAST
to provide email to wireless devices including pagers and cellular phones. This
relationship will provide two-way communication capabilities to these devices
for Internet messaging, including the ability to read, forward, reply to and
delete email messages. This capability ensures users' messages, folders, and
address books are available anywhere, anytime.

     BellSouth. In July 1999, Critical Path entered into an agreement with
BellSouth Telecommunications, Inc., a multi-billion dollar international
communications company, pursuant to which Critical Path will provide Enhanced
Fax Services including Broadcast, Never Busy, Fax Request and Fax Mailbox, as
well as FaxMission Desktop Internet Fax Services.

     Road Runner. In June 1999, Critical Path entered into an agreement with
Road Runner, a joint venture among affiliates of Time Warner, MediaOne,
Microsoft, Compaq and Advance/Newhouse. Pursuant to this agreement, Critical
Path provides Road Runner customers with FaxMission Internet Fax services that
are fully branded under the Road Runner name as FaxRunner.

     Ameritech. In March 1999, Critical Path entered into a five year agreement
with Ameritech Services, Inc., pursuant to which Critical Path will provide to
Ameritech's customers, Enhanced Fax Services including Never Busy, Fax Mailbox,
Broadcast Fax, Fax Request, as well as Internet Fax Services including Internet
Fax Inbound and Internet Fax Outbound.

     America Online/ICQ. In January 1999, Critical Path entered into an
agreement with ICQ, a subsidiary of America Online, pursuant to which Critical
Path provides email hosting services which are 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. Critical Path's
agreement with ICQ also provides for the integration of features of the ICQ
instant messaging service with Critical Path's standard email services and its
offering of these integrated services to other customers. In April 1999,
Critical Path expanded its relationship with America Online to include AOL Latin
America and AOL Enterprise.

     US West. In December 1998, Critical Path entered into an agreement with US
West, pursuant to which it provides email services to US West's telephone
customers. Critical Path believes that US 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 enterprise Internet customers through an email
viewer.

     In March 1997, Critical Path entered into an agreement with US West,
pursuant to which it will provide Enhanced Fax Services including Broadcast Fax,
Never-Busy, Fax Mail, Fax Request, and SMARTLIST, to US West's customers. In
February 1998, Critical Path expanded its relationship with US West to include
FaxMission and Fax to email.

     E*TRADE. In September 1998, Critical Path entered into an agreement with
E*TRADE, an online brokerage services company, pursuant to which each party will
include the other in certain advertising campaigns, including E*TRADE's
international and strategic partner relationships. Critical Path will also
provide email services to users of E*TRADE's Internet access services. E*TRADE
uses Critical Path's email services to extend its brand and value-added services
to its fast-growing customer base. Critical Path is currently renegotiating the
components of the services offered under its agreement with E*TRADE.

     Sprint. In September 1998, Critical Path entered into an agreement with
Sprint's IP Business Services pursuant to which Critical Path provides 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. Critical Path provides a dedicated customer
support number and a sales support center to

                                       15
<PAGE>   16

support Sprint's sales representatives. In January 2000, Sprint and Critical
Path executed an amendment to this agreement expanding the relationship,
allowing Sprint to provide additional messaging services to its small business
customers.

     Bell Atlantic. In August 1998, Critical Path entered into an agreement with
Bell Atlantic. Pursuant to this agreement, Critical Path will provide Enhanced
Fax Services including Fax Broadcast, Fax Request, Never-Busy, Fax Mailbox, and
Internet Fax Services including FaxMission and Fax to email. Critical Path also
provides Bell Atlantic with services for branding under the Bell Atlantic name,
support and telemarketing.

     Network Solutions. In May 1998, Critical Path entered into an agreement
with Network Solutions, a registrar of Internet domain names, pursuant to which
Critical Path provides email outsourcing services to users of Network Solutions'
website. In exchange for Critical Path's services, Network Solutions will
provide domain name registration services for Critical Path's 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.

     MCI Worldcom. In December 1997, Critical Path entered into an agreement
with MCI Worldcom to provide enterprise messaging integration services. In
February 2000, Critical Path and MCI expanded this relationship to include
additional Critical Path services such as Webmail, POP3, IMAP and Microsoft
Exchange hosting services.

SALES AND MARKETING

     Sales Strategy. Critical Path's sales efforts target all market segment
audiences through direct and indirect channels. Critical Path maintains its own
direct sales force to introduce and educate prospective customers and partners
about its service. The direct sales group targets larger ISPs,
telecommunications companies, medium to large corporate customers, large web
hosting companies and high-trafficked web portals. Critical Path currently has
domestic offices in the San Francisco, Irvine, San Jose, New York, Phoenix,
Boston, Seattle, Los Angeles, Chicago, Atlanta, Denver and Washington D.C.
metropolitan areas. Critical Path currently has international offices in
Argentina, Brazil, Denmark, England, France, Germany, Ireland, Italy and
Switzerland. Within Critical Path's 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, which conducts sales
activities over the phone. The target markets of the telesales group are smaller
ISPs, web hosting companies and corporations. The 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 Critical Path's 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 Critical Path's
partners to offer its services to their end-users. To gain market presence and
market share overseas, Critical Path teams with leading distributors, resellers
and system integrators that have strong industry backgrounds and market presence
in their respective markets and geographic regions. Resellers include:
Ameritech, BellSouth, British Telecommunications, GTS, MCI Worldcom, Peregrine,
Qwest, Sprint and US West.

     Marketing Strategy. Critical Path's marketing strategy is focused on media
relations and public relations in order to develop a reputation as an industry
leader for Internet messaging. Critical Path will use focused print and online
advertising campaigns for lead generation. Direct marketing is used to target
customer segments. 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 Critical Path's business-to-business
brand presence.

     Enhanced Services Development. Critical Path's product management and
marketing organizations focus on marketing and service development. This team
determines Critical Path's application pipeline and

                                       16
<PAGE>   17

feature development schedules and provides direction for engineering,
operations, sales and support teams. Critical Path has product marketing
managers for each of its product areas who are responsible for defining
strategies to address specific customer needs within each product category.
These managers work with its technical service managers, who are in turn
responsible for service strategies and development plans.

     Critical Path's service management team focuses on developing provisioning
and billing, messaging and directory services and mail center technology. In
addition, Critical Path's products and 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 products and services development process
incorporates input from a variety of sources, including Critical Path's current
and potential customers, and refines this information through a business
prioritization process.

TECHNOLOGY

     In offering messaging services, Critical Path employs advanced software and
hardware, combining internal expertise with industry standard technology to
create a proprietary infrastructure.

     Mail Center Technology. Critical Path has created a proprietary email
system, Mail Center Technology, or 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 by ISPs, telecommunications providers, 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. Critical Path has written proprietary load-balancing and messaging
software, and uses Oracle Corporation databases 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 messaging services. MCT
hardware and software consists of Sun Microsystems servers running Solaris,
Cisco routers, EMC redundant storage arrays, Veritas software and rackmounted
Intel processor-based servers running FreeBSD, a free, standards-based operating
system supported by the growing open source engineering community.

     All aspects of MCT are deployed in a redundant configuration 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 messaging 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.

     Account Provisioning Protocol. Critical Path has created a proprietary
Account Provisioning Protocol, or APP, for account creation and maintenance. APP
enables accounts transitioning from other services or legacy systems to be
bulk-loaded, tested, replicated and deployed on Critical Path's service
automatically. This protocol 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, 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. Critical Path maintains data centers with
third parties in San Francisco, Sunnyvale and Palo Alto, California; Salt Lake
City, Utah; Sterling, Virginia; London, England; and Munich, Germany. Critical
Path also plans to maintain a data center in Asia. 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, Critical
Path has reduced the likelihood that its customers will suffer downtime as a
result of network outages. Critical Path's backbone architecture and
interconnection strategy consists of clear channel DS-3 connections and direct
100 MB/sec Ethernet connections. Critical Path's 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.

                                       17
<PAGE>   18

     Critical Path currently has bilateral peering arrangements in place with
the following organizations: aussie.net, AboveNet Communications, Compaq/Digital
Equipment Corporation, Concentric Networks, Dacom, DataResearch Associates,
DIGEX, Direct Network Access, Electric Lightwave, Excite@Home, Exodus
Communications, Frontier GlobalCenter, GTE Internetworking/Genuity, Globix,
Hanaro Telecom, Hurricane Electric, Inet, MAXIM, Paradox Digital, Pilot Network
Services, Route Server Next Generation, Singapore Telecom, Telestra Corporation,
Tycho Internet, Verio, ViaNet Communications, Web Professionals, WebTV Networks,
XMISSION, and Zocalo. In addition to its peering connections, Critical Path
currently purchases additional Internet access from MCI WorldCom and Sprint,
through their relationships with AboveNet Communications Inc.

     Network Security. Critical Path has created a custom firewall solution to
reduce the incidence of network security breaches, utilizing Cisco routers for
firewall hardware. To enhance security for the network, Critical Path's staff
members monitor the network and hardware 24 hours a day, seven days a week. Any
suspicious activity is reported and investigated immediately.

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

     Spam Blocking. Critical Path's basic hosted email and web-based email
services include comprehensive spam (unsolicited commercial email) prevention at
no additional charge. This spam prevention is currently being used to screen
messages for all customers.

     Critical Path's engineers have written proprietary software that
automatically screens incoming messages for telltale items in message headers
and subject lines. Critical Path has also developed a comprehensive database of
commonly forged addresses and frequently abused domain names. Most additions to
the "black list" have been reported by Critical Path's end-users, who are
encouraged to notify Critical Path 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, Critical Path's
personnel monitor incoming messages 24 hours a day, seven days a week. Critical
Path is part of a group of key network operators and ISPs working to develop
technologies and other measures aimed at protecting users from junk email.
Critical Path has representatives serving on the Coalition Against Unsolicited
Commercial email, the leading national organization lobbying for anti-spam
legislation. Critical Path's Acceptable Use Policy explicitly states that
partners and customers may not use its service to send unsolicited bulk email.

     Customer Support. Critical Path provides customer support 24 hours a day,
seven days a week by contractual agreement. Critical Path's customer support
service consists of two tiers. Tier 1 includes technical support in response to
end-user inquiries. Although its customers typically provide Tier 1 support
directly to their end-users, they can outsource this function and Critical Path
can provide Tier 1 support to their end-users via email or web-based support.
Critical Path also provides support information on its website.

     Tier 2 support includes technical support for customers' systems
administrators. Critical Path's 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.

                                       18
<PAGE>   19

     In an effort to further improve customer satisfaction, Critical Path has
deployed customer relationship management 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 Critical Path's
ability to track recurring customer issues that will identify opportunities for
service improvements. Critical Path's staff of trained technical
representatives, coupled with leading edge monitoring and tracking tools allows
it to successfully serve the needs of its clients.

  Research and Development

     The Company's products and services are based on internally developed
systems. The Company must continually improve these systems to accommodate the
level of use of its products and services. In addition, the Company may add new
features and functionality to its products and that could result in the need to
develop or license additional technologies. The Company's inability to add
additional software and hardware or to upgrade its technology or network
infrastructure could have adverse consequences. These consequences include
service interruptions, impaired quality of the users' experience and the
diversion of development resources. The Company's failure to provide new
features or functionality also could result in these consequences. The Company
may not be able to effectively upgrade and expand its systems in a timely manner
or to integrate smoothly any newly developed or purchased technologies with its
existing systems. These difficulties could harm or limit its ability to expand
its business. See "Risk Factors -- The inability to expand our systems may limit
our growth" and "-- System failures could harm our business."

     The Company incurred $454,000, $2.1 million and $7.7 million in research
and development expenses in 1997, 1998 and 1999, respectively. The Company
anticipates that it will continue to devote significant resources to product
development in the future as it adds new features and functionality to its
products and services. The market in which the Company competes is characterized
by rapidly changing technology, evolving industry standards, frequent new
service and product announcements, introductions and enhancements and changing
customer demands. Accordingly, the Company's future success will depend on its
ability to adapt to rapidly changing technologies, to adapt its services to
evolving industry standards and to continually improve the performance, features
and reliability of its products and services and service offerings and evolving
demands of the marketplace. The failure of the Company to adapt to such changes
would harm the Company's business. In addition, the widespread adoption of new
Internet, networking or telecommunications technologies or other technological
changes could require substantial expenditures by the Company to modify or adapt
its services or infrastructure. See "Risk Factors -- Our failure to manage
growth could harm us;" "-- We must keep pace with rapid technological change to
remain competitive" and "-- We need to develop new services, features and
functions in order to expand."

COMPETITION

     The market for Internet-based messaging services is characterized by
companies that elect to develop and maintain in-house solutions and companies
that seek outsourcing arrangements for their messaging service. For customers
seeking outsourcing arrangements, Critical Path competes with email service
providers, such as USA.NET, mail.com and Commtouch. For those seeking
product-based solutions Critical Path competes with Sun/Netscape Alliance,
Microsoft, Software.com and Lotus Development Corporation. These companies could
potentially leverage their existing capabilities and relationships to enter the
hosted messaging and collaboration 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 messaging
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 Critical Path expands its service offerings, Critical
Path expects to encounter increased competition in the development and delivery
of these services. Many of Critical Path's current and potential competitors
have longer operating histories, larger customer bases, greater brand
recognition and significantly greater financial, marketing and other resources
than it does and may enter into strategic or commercial relationships with
larger, more established and well-financed companies. Certain competitors may be
able to enter into such strategic or commercial relationships on more

                                       19
<PAGE>   20

favorable terms. Further, certain competitors may offer services at or below
cost. In addition, new technologies and the expansion of existing technologies
may increase competitive pressures on Critical Path. Increased competition may
result in reduced operating margins and loss of market share.

     Critical Path believes that its 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 expense and effort associated with attracting and retaining
       qualified technical personnel to manage them;

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

     - 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 Critical Path's competitive positioning, it may not be
able to compete successfully against current and future competitors, and
competitive pressures Critical Path faces could have a material adverse effect
on its business, operating results and financial condition.

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 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.

                                  RISK FACTORS

                         RISKS RELATED TO OUR BUSINESS

WE HAVE A LIMITED OPERATING HISTORY UPON WHICH YOU CAN EVALUATE OUR BUSINESS AND
FACE RISKS ASSOCIATED WITH EARLY STAGE COMPANIES THAT MAY ADVERSELY AFFECT OUR
BUSINESS.

     Because we have had 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. 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;

     - Integrate the operations of the companies that we have recently acquired;

     - Manage growing domestic and international operations;

     - Create and maintain strategic relationships;

     - Expand sales and marketing activities;

     - Expand our customer base and retain key clients;

     - Introduce new services;

     - 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 HAVE A HISTORY OF LOSSES, EXPECT CONTINUING LOSSES AND WE MAY NEVER ACHIEVE
PROFITABILITY.

     As of December 31, 1999, we had an accumulated deficit of approximately
$129.5 million. We have not achieved profitability in any period, and expect to
continue to incur net losses for the foreseeable future. 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 operating results and
financial condition in the near term.

     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 end-to-end Internet messaging and collaboration
solutions, 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 revenues do not correspondingly increase, our operating results and
financial condition could be negatively affected.

     Should we continue to incur net losses in future periods, we may not be
able to increase the number of employees or investment in capital equipment,
sales and marketing programs, and research and development in accordance with
our present plans. 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 INTERNET
MESSAGING AND COLLABORATION SOLUTIONS MARKET, 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 messaging and
collaboration solutions market. Our revenues could fall short of expectations if
we experience delays or cancellations of even a small number of orders. We often
offer volume-

                                       21
<PAGE>   22

based pricing, which may affect operating margins. A number of factors are
likely to cause fluctuations in operating results, including, but not limited
to:

     - Continued growth of the Internet in general and of messaging and
       collaboration 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 business and infrastructure;

     - Technical difficulties or system outages;

     - The announcement or introduction of new or enhanced services by
       competitors;

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

     - The pricing policies of competitors;

     - Failure to increase international sales; and

     - Governmental regulation surrounding the Internet and messaging in
       particular.

     In addition to the factors set forth above, 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
have incurred and expect to continue to incur substantial non-cash charges
associated with the grant of warrants to our customers and other parties with
which we have commercial relationships. For example, we recognized a $27.4
million non-cash charge to advertising expense during 1999 in connection with
the amortization of a warrant to America Online.

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

FURTHER ACQUISITIONS COULD RESULT IN DILUTION, OPERATING DIFFICULTIES AND OTHER
HARMFUL CONSEQUENCES.

     We expect to acquire or invest in additional businesses, products, services
and technologies that complement or augment our service offerings and customer
base. Since January 1999, we have completed the acquisition of seven companies
for an aggregate consideration consisting of cash, common stock and the
assumption of stock options and warrants totaling approximately $1.1 billion. In
addition, in February 2000, we agreed to acquire RemarQ for common stock valued
at approximately $267.0 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, other than our agreement
with RemarQ as described above, and cannot assure you that any of these
discussions or the RemarQ agreement 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 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 to pay for some acquisitions by issuing additional common stock,
which would dilute current 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 favorable terms. 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 operating expenses.

                                       22
<PAGE>   23

WE WILL FACE TECHNICAL, OPERATIONAL AND STRATEGIC CHALLENGES THAT MAY PREVENT US
FROM SUCCESSFULLY INTEGRATING DOCSPACE, ISOCOR, FAXNET, XETI, AMPLITUDE, DOTONE
FABRIK COMMUNICATIONS AND REMARQ.

     Acquisitions involve risks related to the integration and management of
acquired technology, operations and personnel. The integration of docSpace,
ISOCOR, FaxNet, Xeti, Amplitude, dotOne, Fabrik Communications and RemarQ into
our business has been and will be a complex, time consuming and expensive
process and may disrupt our business if not completed in a timely and efficient
manner. We must operate as a combined organization utilizing, common information
and communication systems, operating procedures, financial controls and human
resources practices. In particular, we are currently evaluating, upgrading or
replacing our financial information systems and establishing uniformity among
the systems of the acquired businesses. We may encounter substantial
difficulties, costs and delays involved in integrating the operations of our
subsidiaries, including:

     - potential incompatibility of business cultures;

     - perceived adverse changes in business focus;

     - potential conflicts in sponsor, advertising or strategic relationships;
       and

     - the loss of key employees and diversion of the attention of management
       from other ongoing business concerns.

     Consequently, we may not be successful in integrating acquired businesses
or technologies and may not achieve anticipated revenue and cost benefits. We
also cannot guarantee that these acquisitions will result in sufficient revenues
or earnings to justify our investment in, or expenses related to, these
acquisitions or that any synergies will develop. If we fail to execute our
acquisition strategy successfully for any reason, our business will suffer
significantly.

WE HAVE EXPERIENCED RAPID GROWTH WHICH HAS PLACED A STRAIN ON RESOURCES AND OUR
FAILURE TO MANAGE GROWTH COULD CAUSE OUR BUSINESS TO SUFFER.

     We have expanded our operations rapidly and intend to continue this
expansion. The number of our employees increased from 93 on December 31, 1998 to
840 on March 15, 2000. This expansion has placed, and is expected to continue to
place, a significant strain on 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 to properly manage these systems 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.

IF WE FAIL TO EXPAND SALES AND MARKETING ACTIVITIES, WE MAY BE UNABLE TO EXPAND
OUR BUSINESS.

     Our ability to increase revenues will depend on our ability to successfully
recruit, train and retain 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.

     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. 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 encountered 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 revenues. Because
the majority of our sales and marketing personnel have recently joined us and

                                       23
<PAGE>   24

have limited experience working together, our sales and marketing organizations
may not be able to compete successfully against the larger and more experienced
sales and marketing organizations of our competitors. If we do not successfully
expand 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 MESSAGING AND COLLABORATION SERVICES AND COULD HARM OUR BUSINESS AND
REPUTATION.

     Our customers have in the past experienced some interruptions in our
messaging 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
January 2000, our customers experienced a service interruption due to an
operating system failure. Our revenues depend on the number of end-users who use
our messaging services. Our business will suffer if we experience frequent or
long system interruptions that result in the unavailability or reduced
performance of 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 customers that require
minimum performance standards, including standards regarding the availability
and response time of messaging 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.

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 revenues from
international operations do not exceed the expense of establishing and
maintaining these operations, our business, financial condition and operating
results will suffer. At present, we have international operations in Argentina,
Brazil, Denmark, France, Germany, Ireland, Italy, Switzerland and the United
Kingdom and as of December 31, 1999 we derived 24.8% of our revenues from
international sales on a pro forma basis. 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 including U.S. export
       restrictions on encryption technologies;

     - 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 some countries.

     Any of these factors could adversely affect international operations and,
consequently, business and operating results. Specifically, failure to
successfully manage 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.

                                       24
<PAGE>   25

WE DEPEND ON STRATEGIC RELATIONSHIPS AND OTHER SALES CHANNELS AND THE LOSS OF
ANY STRATEGIC RELATIONSHIPS COULD HARM OUR BUSINESS AND HAVE AN ADVERSE IMPACT
ON REVENUES.

     We depend on strategic relationships to expand distribution channels and to
undertake joint product development and marketing efforts. Our ability to
increase revenues depends upon marketing 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 US West,
among others. We depend on a broad acceptance of outsourced messaging services
on the part of potential partners and acceptance of our company as the supplier
for these outsourced messaging services. We also depend on joint marketing and
product development through 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 messaging services in
E*TRADE's international strategic relationships. Our agreements with 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 strategic
relationships, fail to renew these agreements or relationships or fail to
develop new strategic relationships, business will suffer. The loss of any key
strategic relationships would have an adverse impact on current and future
revenue. For example, for the year ended December 31, 1999, E*TRADE accounted
for approximately 15% of our net revenues, excluding the value of stock purchase
rights received by customers. In addition to strategic relationships, we also
depend on the ability of our customers to sell and market our services to their
end-users.

WE MAY NOT BE ABLE TO RESPOND TO THE RAPID TECHNOLOGICAL CHANGE OF THE INTERNET
MESSAGING AND COLLABORATION 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 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 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 be unable to use new technologies
effectively or adapt services to customer requirements or emerging industry
standards.

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 these attempts are
successful, customers' confidential information, including customers' profiles,
passwords, financial account information, credit card numbers or other personal
information could be breached. We may be liable to our customers for any breach
in security and a 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

                                       25
<PAGE>   26

to alleviate problems caused by any breach. Failure to prevent security breaches
may have a material adverse effect on business and operating results.

WE WILL CONTINUE TO 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 a substantial portion of our revenues have been derived from
sales of email service offerings and we currently expect that email service
offerings will account for a substantial portion 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 MESSAGING 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, which currently
offers email products primarily to Internet service providers that provide
access to the Internet; web hosting companies; web sites intended to be major
starting sites 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 current competitors increase the
sophistication of their offerings and as new participants enter the market. Many
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 delay would also
allow competitors additional time to improve their service or product offerings,
and 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.

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 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
MESSAGING TRAFFIC.

     We must continue to expand and adapt our network infrastructure as the
number of users and the amount of information we 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 services to date, the ability of our
network to connect and manage a substantially

                                       26
<PAGE>   27

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
messaging traffic increases or upgrade our systems and infrastructure to
accommodate future traffic levels, which may cause service degradation or
outages. 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 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 customers' changing requirements in a timely manner or at all.

BECAUSE WE PROVIDE MESSAGING AND COLLABORATION 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. To
date we have not experienced a significant adverse effect from these
interruptions. However, because we provide messaging and collaboration services
over the Internet, interruptions or delays in Internet transmissions will
adversely affect customers' ability to send or receive their 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 Level 3, Qwest,
Exodus and TeleHouse to transmit 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 messaging 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 sales. If we did not increase
prices in response to rising access costs, 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 FAILURES, WE MAY NOT BE ABLE TO PROVIDE ADEQUATE SERVICE
AND OUR BUSINESS AND REPUTATION COULD BE DAMAGED.

     Our ability to successfully receive and send messages and provide
acceptable levels of customer service largely depends on the efficient and
uninterrupted operation of computer and communications hardware and network
systems. 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 minimum performance standards,
and could have a material adverse effect on 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 senior
management and other key personnel, many of whom have worked together for only a
short period of time. For example, our Chief Operating Officer and Chief
Financial Officer have joined us within the past three months. The loss of the
services of any senior management or other key personnel, including the
President, David Thatcher, and Chief Executive Officer, Douglas Hickey, could
materially and adversely affect business results. We do not have long-term
employment agreements with any executive officers 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,

                                       27
<PAGE>   28

train or retain qualified personnel. In particular, we may not be able to hire a
sufficient number of qualified software developers.

UNKNOWN SOFTWARE DEFECTS COULD DISRUPT 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. We may not
discover software defects that affect 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, defects may
occur in the software. These defects could cause service interruptions, which
could damage our reputation or increase service costs, cause us to lose revenue,
delay market acceptance or divert development resources, any of which could
cause business to suffer.

WE MAY NEED ADDITIONAL CAPITAL AND RAISING ADDITIONAL CAPITAL MAY DILUTE
EXISTING SHAREHOLDERS.

     We believe that existing capital resources will enable us to maintain
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
capital requirements vary materially from those current 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 INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS.

     We regard our copyrights, service marks, trademarks, trade secrets and
similar intellectual property as critical to our success, and we rely on
trademark and copyright law, trade secret protection and confidentiality and/or
license agreements with employees, customers and partners to protect proprietary
rights. Despite these precautions, unauthorized third parties may infringe or
copy 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 several patents pending in the United States and may
seek additional patents in the future. We do not know if the patent application
or any future patent application will be issued with the scope of the claims
sought, if at all, or whether any patents received 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 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 copyrights, trademarks and
similar proprietary rights belonging to us. In addition, other parties have
asserted and may assert infringement claims against us. For example, a company
that we acquired is a party to a lawsuit involving alleged infringement of a
third party's patent. The recently acquired company has denied the allegations
of infringement and has made counterclaims. Although we have not received notice
of any other 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 business, including claims of alleged
infringement of 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 operating our business.

WE MAY NEED TO LICENSE THIRD-PARTY TECHNOLOGIES AND WE FACE RISKS IN DOING SO.

     We intend to continue to license certain technology from third parties,
including 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

                                       28

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 proprietary technology, and an inability to
generate revenues from new technology sufficient to offset associated
acquisition and maintenance costs. An 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.

THE TRADING PRICES AND VOLUMES OF OUR STOCK HAVE BEEN VOLATILE AND WE EXPECT
THAT THIS VOLATILITY WILL CONTINUE.

     Our stock price and trading volumes have 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 results of operations;

     - Changes in or failure to meet securities analysts' expectations;

     - Announcements of technological innovations and acquisitions;

     - Introduction of new services by us or our competitors;

     - 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
on 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 messaging 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
messaging services 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
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.

WE MAY HAVE LIABILITY FOR INTERNET CONTENT AND WE MAY NOT HAVE ADEQUATE
LIABILITY INSURANCE.

     As a provider of messaging 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 our
services. 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.

                                       29
<PAGE>   30

     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
stockholders may need to be used 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
business and operating results, or could result in the imposition of criminal
penalties.

FUTURE SALES OF OUR COMMON STOCK MAY DEPRESS THE PRICE OF OUR COMMON STOCK.

     As of March 15, 2000, we had approximately 57.9 million shares of common
stock outstanding. Sales of a substantial number of shares of common stock in
the public market could cause the market price of our common stock to decline.
In the near future, 7.6 million shares will become eligible for sale under an
S-3 registration statement that we will file to meet our registration rights
obligations in connection with recent acquisitions. In addition, we expect the
RemarQ acquisition to close in late March. Approximately 4.0 million shares of
our common stock will be freely tradeable upon the closing of this transaction.
Certain of our shareholders and warrantholders have registration rights with
respect to the common stock and common stock issuable under the warrants. See
"Description of Capital Stock -- Registration Rights".

OUR DIRECTORS, EXECUTIVE OFFICERS AND PRINCIPAL SHAREHOLDERS WILL BE ABLE TO
EXERT SIGNIFICANT INFLUENCE OVER US.

     After this offering, our directors, executive officers and principal
shareholders will beneficially own a substantial portion 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 significant corporate
transactions. This concentration of ownership may also delay or prevent a change
in control of our company.

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 our company. 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 stockholder 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.

ITEM 2. PROPERTIES

     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. In addition,
in January 2000, we entered into a lease for an additional 40,000 square feet of
office space in San Francisco, California. In addition, we lease facilities in
Argentina, Canada, Denmark, France, Germany, Ireland, Italy, Switzerland and the
United Kingdom. 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.

ITEM 3. LEGAL

     The Company recently acquired The docSpace Company, which is involved in a
patent infringement action with Tumbleweed Communications Corp. The lawsuit
relates to a Tumbleweed patent that describes

                                       30
<PAGE>   31

an apparatus for delivering documents via the Internet. docSpace has denied the
allegations of infringement, and has counterclaimed for violations of the
antitrust laws and related state law claims. This case is in the preliminary
phase and the Company is not currently able to assess the impact, if any, on its
financial position or results of operations.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     There were no submissions of matters to a vote of security holders during
the quarter ended December 31, 1999.

ITEM 7. 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 of Critical Path, Inc.
appearing elsewhere in this Information Statement. 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 Information Statement.

OVERVIEW

     Critical Path was founded in February 1997 to deliver email hosting
solutions to Internet service providers, telecommunications providers, Web
hosting companies, Web portals and corporations. From inception to October 1997,
the Company's 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. The Company initiated its
email hosting service in October 1997 and has continued to make investments to
improve the quality of its service. In December 1997, the Company enhanced its
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 as "POP3". In January 1999,
the Company further enhanced its service with the addition of an offering based
on the Lightweight Directory Access Protocol, or "LDAP," a directory software
protocol.

  Operations

     The Company continues to derive most of its revenues through the sale of
electronic messaging services and products. The Company's service revenues are
derived primarily from contractual relationships that provide for revenues based
either on contractual rates per mailbox or per message, non-refundable fixed
payments or as a percentage of customer-generated email advertising revenues.
These contracts are typically one to three years in length. 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.

     Revenues for software licenses for which collection of the resulting
receivable is deemed probable are recognized upon delivery of the licensed
software. Revenues from software maintenance are recognized ratably over the
maintenance term. Agreements with some of the Company's customers require
minimum performance standards regarding the availability and response time of
the Company's messaging services. If the Company fails to meet these standards,
customers could terminate their relationships and the Company could be subject
to contractual monetary penalties.

     Revenues from the Company's enhanced facsimile, long distance and other
services are recognized as the services are performed. Amounts billed or
received in advance of service delivery are recorded as deferred revenue.

     The Company expects to expand its operations and employee base, including
its sales, marketing, technical, operational and customer support resources. In
particular, the Company intends to expand its sales force to deliver its
complete end-to-end Internet messaging and collaboration solutions to customers
in its five target markets: ISPs, telecommunication providers, Web hosting
companies, Web portals and corporations. The Company also intends to further
develop new and existing strategic relationships to expand its distribution
channels and to undertake joint product development and marketing efforts.

     The Company intends to increase the number of worldwide sales offices and

United States and data centers in the United States, Germany, and the United
Kingdom. The Company expects to open an additional data center in Asia.

     Future investments in technology may involve the development, acquisition
or licensing of technologies that complement or augment the Company's existing
services and technologies.

     During 1998, the Company recorded aggregate unearned compensation totaling
approximately $19.9 million in connection with certain sales of stock and the
grant of certain stock 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 $448,000,
$217,000, $269,000 and $1.7 million was amortized in the quarters ended March
31, June 30, September 30 and December 31, 1998, respectively. In January and
March 1999, the Company granted options resulting in an additional $18.1 million
of unearned compensation. Amortization of unearned compensation was
approximately $3.7 million, $4.9 million, $4.8 million and $4.3 million during
the quarters ended March 31, June 30, September 30 and December 31, 1999,
respectively. The Company expects aggregate per quarter amortization related to
unearned compensation of between $3.4 million and $2.4 million during 2000,
between $2.0 million and $1.3 million during 2001, and between $1.0 million and
$634,000 during 2002.

  Warrants

     In January 1999, the Company entered into an agreement with ICQ, a
subsidiary of America Online, Inc., pursuant to which the Company provides email
hosting services that are 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 Critical Path in
exchange for a warrant to purchase 2,442,766 shares of Common Stock, issuable
upon attainment of each of five milestones. The Company believes that this
agreement will have a significant current and potential future impact on the
Company's results of operations. The following table summarizes the shares
underlying each milestone and the related exercise price:

     In the quarter ended June 30, 1999, the Company amended the vesting terms
of the agreement with ICQ. The revised vesting terms did not impact the shares
underlying the first milestone, which vested immediately upon the execution of
the agreement. The shares underlying each of the remaining milestones vest on
the date in a quarter in which ICQ completes a minimum registration of 100,000
sub-branded ICQ mailboxes, compared to 250,000 sub-branded ICQ mailboxes as
provided in the terms of the original agreement. The amended agreement also
provides that only one milestone may be achieved on a quarterly basis. The
Company believes it is probable that all milestones will be achieved.

     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 are remeasured at each
subsequent reporting date until each

                                       38
<PAGE>   39

sub-branded ICQ mailbox registration threshold is achieved and the related
warrant shares vest, at which time the fair value attributable to that tranche
of the warrant is fixed. In the event such remeasurement results in increases or
decreases from the initial fair value, which could be substantial, these
increases or decreases will be recognized immediately, if the fair value of the
shares underlying the milestone has been previously recognized, or over the
remaining term, if not.

     As of December 31, 1999, three of the five milestones had been attained
resulting an aggregate charge to stock-based expenses of $9.2 million during
1999. The remaining shares underlying the fourth and fifth milestones were
remeasured using the December 31, 1999 closing price of $94.38 resulting in a
revised fair value of the warrant of $109.7 million. The Company expects that
future changes in the trading price of the Company's Common Stock at the end of
each quarter, and at the time certain milestones are achieved, will cause
additional substantial changes in the ultimate amount of the related stock-based
charges.

     In October 1999, the Company entered into an agreement with Qwest
Communications Corporation, pursuant to which the Company will provide email
hosting services to Qwest's customers. As part of the agreement, Qwest agreed to
provide sub-branded advertising for Critical Path in exchange for warrants to
purchase up to a maximum of 3,534,540 shares of Common Stock upon attainment of
each of six milestones. The Company believes that this agreement could have a
significant current and potential future impact on the Company's results of
operations. The following table summarizes the shares underlying each milestone
and the related exercise price:

     The shares underlying those milestones for which achievement is considered
probable are remeasured at each subsequent reporting date, beginning at December
31, 1999, until each sub-branded Qwest mailbox registration threshold is
achieved and the related warrant shares vest, at which time the fair value
attributable to that tranche of the warrant is fixed. In the event such
remeasurement results in increases or decreases from the initial fair value,
which could be substantial, these increases or decreases will be recognized
immediately, if the fair value of the shares underlying the milestone has been
previously recognized, or over the remaining term, if not.

     Using the Black-Scholes option-pricing model and assuming a term of 5 years
and expected volatility of 90%, the initial fair value of the warrants
associated with the first milestone on the effective date of the agreement
approximated $22.2 million, which is being amortized to advertising expense
using the straight-line method over 3 years. The Company expects that future
changes in the trading price of the Company's Common Stock at the end of each
quarter, and at the time certain milestones are considered probable and
achieved, may cause additional substantial changes in the ultimate amount of the
related stock-based charges.

     In December 1999, the Company entered into an agreement with Worldsport
Network Ltd., the exclusive provider of Internet solutions for the General
Association of International Sports Federations ("GAISF") and a majority of the
international federations it recognizes. Worldsport will offer Critical Path's
advanced Web-based email and calendaring services to the entire GAISF network
and its members. As part of the agreement, Worldsport agreed to provide
sub-branded advertising for the Company in exchange for warrants to purchase up
to a 1.25% equity interest in the Company on a fully diluted basis upon
attainment of each of five milestones. The warrants are exercisable for five
years after becoming vested. Any warrants not vested within five years of the
date of the agreement will be cancelled. The Company believes that this
agreement could

                                       39

     The shares underlying those milestones for which achievement is considered
probable are remeasured at each subsequent reporting date, beginning at December
31, 1999, until each sub-branded Worldsport mailbox registration threshold is
achieved and the related warrant shares vest, at which time the fair value
attributable to that tranche of the warrant is fixed. In the event such
remeasurement results in increases or decreases from the initial fair value,
which could be substantial, these increases or decreases will be recognized
immediately, if the fair value of the shares underlying the milestone has been
previously recognized, or over the remaining term, if not.

     As of December 31, 1999, none of the milestones were considered probable
and, as a result, no deferred compensation associated with these warrants was
recognized. The Company expects that future changes in the trading price of the
Company's Common Stock at the end of each quarter, and at the time subsequent
milestones considered probable and are achieved, will cause additional
substantial changes in the ultimate amount of the related stock-based charges.

     In December 1999, the Company entered into an agreement with one of its
lessors, in connection with an office lease, pursuant to which the lessor is
entitled to purchase up to a maximum of 25,000 shares of Common Stock. The
warrants may be exercised beginning January 1, 2000 through December 20, 2006 at
a price of $90.00 per share. The warrants vest at the beginning of each month on
a straight-line basis in the amount of 521 shares per month.

     Using the Black-Scholes option pricing model and assuming a term of 6 years
and expected volatility of 90%, the fair value of the warrants on the effective
date of the agreement approximated $2.0 million, which will be amortized to
general and administrative expenses using the straight-line method over 10 years
beginning January 2000.

     In January 2000, the docSpace Company entered into an agreement with AT&T
Corporation, pursuant to which the docSpace Company will provide secure
messaging services to AT&T's Internet portal customers. As part of the
agreement, AT&T agreed to provide marketing, publicity, promotional and
provision branding for docSpace, and upon completion of the acquisition for
Critical Path, in exchange for a warrant to purchase up to a maximum of 349,123
shares of Common Stock upon attainment of each of three milestones. The Company
believes that this agreement could have a significant current and potential
future impact on the Company's results of operations. The following table

     The Company believes that all shares underlying these warrants are
considered probable of issuance. The shares underlying the warrants associated
with first milestone were fully vested on the inception date of the agreement.
The shares underlying the remaining warrants associated with the second and
third milestone will be remeasured at each subsequent reporting date, beginning
at March 31, 2000, until each sub-branded AT&T mailbox registration threshold is
achieved, and the related warrant shares vest, at which time the fair value
attributable to that tranche of the warrant is fixed. In the event such

     Using the Black-Scholes option-pricing model and assuming a term of 7 years
and expected volatility of 90%, the initial fair value of all the warrants on
the effective date of the agreement approximated $26.4 million, which is
included as a component of the purchase price of the acquisition. The warrants
underlying the second and third milestones will be remeasured at each subsequent
reporting date until the milestone requirements are met. The remeasured amounts
will be capitalized and amortized to advertising expense using the straight-line
method over 3 years.

     The Company has incurred significant losses since its inception, and as of
December 31, 1999 had an accumulated deficit of approximately $129.5 million.
The Company intends to continue to invest heavily in sales and marketing,
continued development of its network infrastructure, and continued technology
enhancements. In addition, the Company expects to continue to expand its
business through acquisitions and internal development. The Company expects to
continue to incur substantial operating losses for the foreseeable future.

     In view of the rapidly evolving nature of the Company's business, recent
acquisitions, and limited operating history, the Company believes that
period-to-period comparisons of revenues and operating results, including 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 December 31, 1999, the Company had 488 employees, in comparison
with 93 employees at December 31, 1998. The Company does not believe that its
historical growth rates for revenue, expenses, or personnel are indicative of
future results.

</TABLE>

  Net Revenues

     Net revenues increased to $16.2 million in 1999 from $897,000 in 1998.
These increases in net revenue resulted from a substantial increase in the
number of email boxes the Company hosted during 1999 in comparison with the
previous year, as well as from the contribution to current revenues of acquired
companies' revenue streams. At December 31, 1999, the Company hosted 11.1
million active email boxes compared to 800,000 email boxes at December 31, 1998.
In addition, the Company recognized $1.0 million from licensing its software in
1999.

     In connection with certain customer contracts executed in 1998, the Company
granted warrants and stock purchase rights to purchase Series B Convertible
Preferred Stock. The fair value of these warrants and stock purchase rights,
determined 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 $231,000 and $106,000 for the years
ended December 31, 1998 and 1999, respectively.

     In early 1998, the Company executed agreements with E*TRADE, an online
brokerage services company, and Verio, a web hosting organization, pursuant to
which the Company derives revenue for providing messaging services. During the
years ended December 31, 1998 and 1999, E*TRADE accounted for approximately 62%
and 15%, respectively, of the Company's net revenues, excluding the value of
stock purchase rights received by customers. During these same periods, Verio
accounted for approximately 30% and 4%, respectively, of the Company's net
revenues.

  Cost of Net Revenues

     Cost of net revenues consists principally of costs incurred in the delivery
and support messaging services, including depreciation of capital equipment used
in network infrastructure, amortization of purchased technology included in
intangibles, and personnel costs incurred in operations and customer support
functions.

                                       42
<PAGE>   43

During 1999, these costs were $21.6 million or 133% of net revenues, in
comparison with costs of $2.3 million or 262% of net revenues, for 1998.
Significant acquisitions of equipment for data centers have been made over the
past 12 months, and as a result depreciation expense of networking equipment
during 1999 increased substantially in comparison with the previous year.
Additionally, the Company incurred $3.5 million of consulting and outside
contractor charges during 1999 in its continued effort to enhance its network
and migrate to a new storage platform. Staffing also increased significantly in
operations and customer support during 1998 and 1999, resulting in increased
compensation and other personnel costs. Operations and customer support staff
increased from no employees at December 31, 1997, to 25 employees at December
31, 1998, and further to 174 employees as of December 31, 1999.

     During the year ended December 31, 1999, the Company also incurred a
stock-based charge of approximately $2.0 million in connection with a severance
agreement for a terminated employee. This expense was charged to cost of net
revenues, based on the functions and duties previously performed by the
terminated employee. Furthermore, the Company recognized stock-based charges
associated with stock options granted with an exercise price below market value
on the date of grant to employees involved in the revenue-generating activities
of the Company in the amount of $193,000 and $2.6 million in 1998 and 1999,
respectively. Excluding these special charges, cost of net revenues would have
been $2.2 million or 240% of net revenues and $17.0 million or 105% of net
revenues, respectively.

  Operating Expenses

     Sales and Marketing. Sales and marketing expenses consist principally of
compensation for sales and marketing personnel, advertising, public relations,
other promotional costs, and, to a lesser extent, related overhead. Sales and
marketing expenses during the year ended December 31, 1999, amounted to $13.8
million, or 85.5% of net revenues, in comparison with $1.7 million, or 188.1%,
during the previous year and $244,000 in 1997. Increases in marketing and
promotional expenses, incentive compensation payments to sales personnel, and
increases in compensation associated with additional headcount accounted for the
increase in sales and marketing expenses. Sales and marketing staff increased
from 30 employees to 168 employees at December 31, 1998 and 1999, respectively.
At December 31, 1997, the Company had 2 employees in sales and marketing.

     Research and Development. Research and development expenses consist
principally of compensation for technical staff, payments to outside
contractors, and, to a lesser extent, related overhead. The Company recognizes
research and development expenses, in-process research and development costs, as
they are incurred. Research and development expenses amounted to $7.7 million,
or 47.5% of net revenues, during the year ended December 31, 1999, in comparison
with $2.1 million, or 233.9% of net revenues, for the previous year and $454,000
in 1997.

     These significant increases resulted primarily from increases in personnel
and use of outside contractors as the Company continues to develop and enhance
its messaging service offerings and to develop new electronic messaging
services. Research and development staff increased from 27 employees to 94
employees at December 31, 1998 and 1999, respectively. At December 31, 1997, the
Company had 11 employees in research and development.

     General and Administrative. General and administrative expenses consist
principally of compensation for personnel, fees for outside professional
services, occupancy costs and, to a lesser extent, related overhead. General and
administrative expenses amounted to approximately $14.1 million, or 87.0% of net
revenues, during the year ended December 31, 1999, in comparison with $3.8
million or 425.2% of net revenues, during the previous fiscal year and $358,000
in 1997. These increases were attributable primarily to increases in
compensation associated with additional headcount, higher fees for outside
professional services, and higher occupancy costs. General and administrative
staff increased from 11 employees to 52 employees at December 31, 1998 and 1999,
respectively. At December 31, 1997, the Company had 4 employees performing
general and administrative functions.

  Acquisition-Related Bonus Program

     In connection with its acquisitions of dotOne, Amplitude, Xeti and FaxNet,
the Company established a retention bonus program in the aggregate amount of $14
million to provide incentive for former dotOne, Amplitude, Xeti and FaxNet
employees to continue their employment with Critical Path. Payment of bonuses to
the listed employees will occur one year following the date of acquisition,
unless the listed employees voluntarily terminate their employment with the
Company prior to the respective acquisition's one-year anniversary. The
aggregate amount of the eligible bonuses is adjusted downward at each point that
a former dotOne, Amplitude, and FaxNet employee chooses to terminate his or her
employment with the Company. The amount of any such downward adjustment
corresponds to the amount that the terminating employee would have received had
he or she elected to continue employment with the Company. A ratable share of
the adjusted eligible bonus amount will be accrued and charged to compensation
expense over the respective 12 months commencing on the date the bonuses are
granted.

     As of December 31, 1999, the aggregate, adjusted eligible bonus amount was
$11.6 million, and the ratable charge to 1999 compensation expense was $4.1
million. Based on the functions of the employees scheduled to receive
acquisition bonuses, $520,000 of the compensation charge was allocated to cost
of net revenues and the remaining $3,587,000 was allocated to operating
expenses.

     Similar bonus programs have also been established to provide incentives for
former employees of ISOCOR, docSpace and RemarQ to continue their employment
with Critical Path in the amount of $741,000, $5.0 million, and $2.0 million,
respectively.

  Amortization of Intangible Assets

     In connection with its acquisitions of Fabrik, dotOne, Amplitude, Xeti and
FaxNet, accounted for under the purchase method of accounting, the Company
recorded goodwill and other intangible assets representing the excess of the
purchase price paid over the fair value of net assets acquired. Other intangible
assets primarily include assembled workforce, customer base and existing
technology. The aggregate amortization of these intangibles was $32.3 million in
1999. There were no acquisitions in 1997 or 1998. The Company anticipates that
future amortization of intangibles associated with its 1999 and first quarter
2000 acquisitions will continue to be amortized on a straight-line basis over
their expected useful lives ranging from two to eight years, and will amount to
approximately $90 million per quarter until 2002, approximately $22 million in
2003 and approximately $5 million thereafter until the related goodwill and
other purchased intangibles are fully amortized. It is likely that the Company
will continue to expand its business through acquisitions and internal
development. Any additional acquisitions or impairment of goodwill and other
purchased intangibles could result in additional merger and acquisition related
costs.

  Stock-Based Expenses

     In connection with certain stock option grants and Common Stock issuances
during the years ended December 31, 1998 and 1999, the Company recognized
unearned compensation totaling $19.9 million and $22.3 million, respectively,
which is being amortized over the vesting periods of the related options.
Amortization expense recognized during 1998 and 1999 totaled approximately $2.5
million and $17.6 million, respectively. Approximately $193,000 and $2.6 million
of amortized unearned compensation was allocated to cost of net revenues, and
the remaining $2.4 million and $15.1 million was amortized to operating expenses
for the years ended December 31, 1998 and 1999, respectively. During 1999, the
Company also incurred a one-time stock-based charge of approximately $2 million
in connection with a severance agreement for a terminated employee. This expense
was charged to cost of net revenues.

     The Company incurred stock-based expenses for warrants the Company granted
to ICQ, a subsidiary of AOL, and Qwest, and for Common Stock issued to one other
strategic partner. Amortization of the fair value of these warrants and Common
Stock resulted in stock-based expenses of approximately $29.7 million for the
year ended December 31, 1999.

                                       44
<PAGE>   45

  Interest and Other Income and Interest Expense

     Interest and other income consists primarily of interest earnings on cash
and cash equivalents. Interest and other income amounted to $375,000 and $7.1
million during the years ended December 31, 1998 and 1999, respectively. The
Company completed private placements of equity securities in April 1998,
September 1998, and January 1999, and closed public offerings of Common Stock in
April 1999 and June 1999. As a result, interest income increased significantly
during 1999 in comparison with 1998 due to higher cash balances available for
investing. During the years ended December 31, 1998 and 1999, the Company
incurred interest expense on capital lease obligations and stock-based charges
in the amount of $388,000 and $752,000, respectively, of which $161,000 and
$64,000 related to the amortization of stock-based charges and the remainder to
interest payments on capital lease obligations.

  Income Taxes

     No provision for federal or state income taxes has been recorded as the
Company has incurred net operating losses from its inception through December
31, 1999. As of December 31, 1999, the Company had approximately $94.9 million
of federal and state net operating loss carryforwards, which expire in varying
amounts beginning in, 2012 and 2005, respectively, available to offset future
taxable income. 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 the Company
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. At December 31,
1999, the Company also had research and development credit carryforwards of
approximately $1.2 million and $717,000 for federal and state purposes,
respectively. The research and development credit carryforwards begin to expire
through 2019 for federal purposes, and do not expire for state purposes. Because
there is significant doubt as to whether the Company will realize any benefit
from this deferred tax asset, the Company has established a full valuation
allowance as of December 31, 1999.

     Net revenues increased quarterly due to a continuous increase in the number
of email boxes hosted during the last half of 1998 and 1999, as well as from the
contribution to 1999 revenues of acquired companies' revenue streams.

     Cost of net revenues increased as a result of the depreciation expense
associated with significant acquisitions of equipment for data centers made
during 1999. Additionally, the Company incurred $3.5 million of consulting and
outside contractor charges during 1999 in its continued effort to enhance its
network and migrate to a new storage platform. During the third quarter of 1999,
the Company incurred a one-time stock-based charge of approximately $2 million
in connection with a severance agreement for a terminated employee. This expense
was charged to cost of net revenues, based on the functions and duties
previously performed by the terminated employee. Furthermore, the Company
recognized stock-based charges associated with stock options granted with an
exercise price below market value on the date of grant to employees involved in
the revenue-generating activities of the Company in the amount of $193,000 and
$4.5 million in 1998 and 1999, respectively.

     Operating expenses increased on a quarterly basis as a result of staffing
increases in operations and customer support during the second half 1998 and
1999, resulting in increased compensation and other personnel costs. In
addition, the Company incurred higher fees for outside professional services and
amortization of unearned compensation. Furthermore, the Company's 1999
acquisitions resulted in amortization charges for purchased intangibles as well
as acquisition-related retention bonuses during the second had half of 1999.

  Fluctuations in Quarterly Results

     The Company has incurred operating losses since inception and cannot be
certain that profitability will be achieved on a quarterly or annual basis in
the future. The Company 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 messaging and collaboration services;

     - the ability to attract and retain customers and maintain customer
       satisfaction;

     - the ability to upgrade, develop and maintain systems and infrastructure;

     - the amount and timing of operating costs and capital expenditures
       relating to expansion of the Company's business and infrastructure;

     - technical difficulties or system outages;

     - the announcement or introduction of new or enhanced services by
       competitors;

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

     - the pricing policies of competitors;

     - failure to increase international sales; and

     - governmental regulation surrounding the Internet and email in particular.

     In addition to the factors set forth above, operating results will be
impacted by the extent to which the Company incurs non-cash charges associated
with stock-based arrangements with the employees and non-employees. In
particular, the Company expects to incur substantial non-cash charges associated
with the grant of warrants to ICQ, Inc., a subsidiary of America Online, and may
incur substantial non-cash charges associated with the grant of warrants to
Qwest Communications Corporation and Worldsport Network Ltd. In addition to
amortization, which totaled $9.2 million in 1999, of the initial fair value of
these warrants, future changes in the trading price of the Company's Common
Stock at the end of each quarter and at the date the

                                       47
<PAGE>   48

related milestones are achieved will cause additional substantial changes in the
ultimate amount of such amortization.

LIQUIDITY AND CAPITAL RESOURCES

     The Company's cash and cash equivalents increased by approximately $61.2
million during the year ended December 31, 1999. This net change occurred as the
Company raised approximately $259.8 million in proceeds from the sale of equity
securities, net of issuance costs, and exercise of stock options, used $23.8
million in cash to fund operating activities, paid $116.4 million (net of cash
acquired) to consummate acquisitions, advanced $15.0 million to third parties
and approximately $200,000 to officers pursuant to promissory notes, invested
$7.5 million to obtain equity positions in strategic partners, disbursed $41.8
million to purchase property and equipment, and paid $3.4 million to retire
principal on capital lease obligations and acquire treasury shares. Installation
of network infrastructure equipment in the Company's data centers, license of
new software platforms, purchases of furniture and equipment for new employees,
and leasehold improvements related to expansion of the Company's facilities
accounted for the significant increase in capital expenditures. The Company
expects that investments in property and equipment will continue to grow as the
Company seeks to increase its capacity to provide end-to-end messaging and
collaboration services. Capital lease obligations, including both short-term and
long-term portions, increased approximately $8.3 million, net of principal
repayments, during 1999 as the Company secured financing for a substantial share
of the additions to property and equipment. The Company's capital lease
obligations contain no provisions that would limit the Company's future
borrowing ability.

     In January 1999, the Company 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 net proceeds of $12.5 million. Also in January 1999, the
Company sold 1,090,909 shares of Common Stock for net proceeds of $2.4 million.
In April 1999, the Company received approximately $114.1 million in net proceeds
upon the closing of the Company's initial public offering of Common Stock. In
June 1999, the Company received approximately $140.7 million in net proceeds
upon the closing of its secondary public offering of Common Stock.

     In May 1999, the Company made a minority investment of $3 million in the
common stock of Starmedia Network, Inc. Based on the closing price of
Starmedia's stock at December 31, 1999, the fair value of the Company's
investment was $10.9 million and is recorded in Investments. The excess of the
investment's carrying value over its cost is recorded as an unrealized gain on
investments and included in the equity section of the Company's balance sheet.
The Company made additional investments during 1999 in privately-held companies
totaling $4.5 million.

     In July 1999, the Company advanced $10.0 million to a privately-held
company pursuant to a promissory note. The note bears interest at the prime rate
of interest as stipulated in The Wall Street Journal. The amount was advanced in
connection with the Company's evaluation of the obligor for potential
acquisition. Under the terms of the note, all principal and accrued interest is
repayable within 90 days of written demand by the holder. Upon the decision by
the Company not to proceed with an acquisition of the obligor, the Company
presented a demand notice for repayment on August 18, 1999. All principal and
interest was subsequently paid.

     In August 1999, the Company advanced $5.0 million to docSpace pursuant to a
promissory note. The note bore interest at a rate equal to 8.0% per annum simple
interest. The amount was advanced in connection with the Company's evaluation of
docSpace for potential acquisition. Under the terms of the note, any portion of
the principal and/or interest outstanding on the note may be converted into
Common Stock at the election of docSpace. In March of 2000, the Company
consummated its acquisition of docSpace at which time a portion of this advance
was converted into common stock of docSpace with the remainder offsetting the
cash portion paid.

     The Company believes that existing capital resources will enable it to
maintain current and planned operations for at least the next 12 months.
However, operating and investing activities on a long-term basis may require the
Company to seek additional equity or debt financing. In addition, the Company
may, from

                                       48
<PAGE>   49

time to time, evaluate potential acquisitions of other businesses, products, and
technologies. In the first quarter of 2000, the Company completed its
acquisitions ISOCOR and docSpace and as a result, expended approximately $51.1
million in cash proceeds and other acquisition costs. In addition, the Company
anticipates closing its proposed acquisition of RemarQ on or before March 31,
2000, resulting in $500,000 of estimated cash expenditures. The Company expects
that future acquisitions of businesses and other strategic assets will require
considerable outlays of capital. The Company also expects to incur significant
capital expenditures in connection with its financial accounting integration
system.

RECENT ACCOUNTING PRONOUNCEMENTS

     In December 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin ("SAB") No. 101, "Revenue Recognition in Financial
Statements," which provides guidance on the recognition, presentation, and
disclosure of revenue in financial statements filed with the SEC. SAB No. 101
outlines the basic criteria that must be met to recognize revenue and provides
guidance for disclosures related to revenue recognition policies. Management
believes that the impact of SAB No. 101 will not have a material effect on the
financial position or results of operations of the Company.

     In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS
133"). SFAS 133 establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts (collectively referred to as derivatives), and for hedging activities.
In June 1999, the FASB issued SFAS No. 137, "Accounting for Derivative
Instruments and Hedging Activities -- Deferral of Effective Date of FASB
Statement No. 133" ("SFAS 137"). SFAS 133, as amended by SFAS 137, is effective
for all fiscal quarters of all fiscal years beginning after June 15, 2000, with
earlier application encouraged. Critical Path does not currently use derivative
instruments.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The Company does not have any derivative financial instruments as of
December 31, 1999. However, the Company is exposed to interest rate risk. The
Company employs established policies and procedures to manage its exposure to
changes in the market risk of its marketable securities, which are classified as
available-for-sale as of December 31, 1998. The Company's capital lease
obligations have fixed interest rates and the fair value of these instruments is
affected by changes in market interest rates. The Company believes that the
market risk arising from holdings of its financial instruments is not material.

     In the future, mainly as a result of the Company's acquisition of ISOCOR in
January 2000, a substantial portion of the Company's worldwide operations will
have a functional currency other than the United States dollar. In particular,
the Company will maintain substantial development operations in Ireland, where
the functional currency is the Irish Pound; Germany, where the functional
currency is the German Mark; and Italy, where the functional currency is the
Lira. In addition, a significant portion of the Company's revenues will also be
denominated in currencies other than the United States dollar. Fluctuations in
exchange rates may have a material adverse effect on the Company's results of
operations and could also result in exchange losses. The impact of future
exchange rate fluctuations cannot be predicted adequately. To date, the Company
has not sought to hedge the risks associated with fluctuations in exchange
rates, but may undertake such transactions in the future. There can be no
assurance that any hedging techniques implemented by the Company would be
successful or that the Company's results of operations will not be materially
adversely affected by exchange rate fluctuations.

     Information relating to quantitative and qualitative disclosure about
market risk is set forth in "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources."

COMMERCIAL RELATIONSHIPS

     In December 1998, Critical Path entered into an agreement with US West

through the use of its sales channels, will provide Critical Path assistance in
selling advertising for the email sites of certain customers of Critical Path.
The agreement also provides for the joint development of certain services and
features from time to time. James Smith, a director of the Company, is the
President and Chief Executive Officer of US West Dex. For the year ended
December 31, 1999, US West accounted for approximately $460,000 of Critical
Path's revenues.

     In April 1998, Critical Path entered into an agreement with E*TRADE

agreed to develop certain features for its email services which Critical Path
may make available to other customers in addition to E*TRADE. Christos Cotsakos,

INDEMNIFICATION

     Critical Path's articles of incorporation limit the liability of its
directors for monetary damages arising from a breach of their fiduciary duty as
directors, except to the extent otherwise required by the California
Corporations Code. Such limitation of liability does not affect the availability
of equitable remedies such as injunctive relief or rescission.

     Critical Path's bylaws provide that Critical Path may indemnify its
directors and officers to the fullest extent permitted by California law,
including in circumstances in which indemnification is otherwise discretionary
under California law. Critical Path has also entered into indemnification
agreements with its officers and directors containing provisions that may
require Critical Path, among other things, to indemnify such officers and
directors against certain liabilities that may arise by reason of their status
or service as directors or officers (other than liabilities arising from willful
misconduct of a culpable nature), to advance their expenses incurred as a result
of any proceeding against them as to which they could be indemnified, and to
obtain directors' and officers' insurance if available on reasonable terms.

RELATED TRANSACTIONS POLICY

     Critical Path believes that the foregoing transactions were in its best
interests. It is Critical Path's current policy that all transactions by
Critical Path with officers, directors, 5 percent shareholders and their
affiliates will be entered into only if such transactions are approved by a
majority of the disinterested independent directors, are on terms no less
favorable to Critical Path than could be obtained from unaffiliated parties and
are reasonably expected to benefit Critical Path.

                       REPORT OF INDEPENDENT ACCOUNTANTS

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

     In our opinion, the accompanying consolidated financial statements listed
in the accompanying index present fairly, in all material respects, the
financial position of Critical Path, Inc. and its subsidiaries (the "Company")
at December 31, 1998 and 1999, and the results of its operations and its cash
flows for the period from February 19, 1997 (Inception) to December 31, 1997 and
for the years ended December 31, 1998 and 1999, in conformity with accounting
principles generally accepted in the United States. 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 auditing standards
generally accepted in the United States, 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.

CRITICAL PATH, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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

  The Company

     Critical Path, Inc. was incorporated in California on February 19, 1997.
Critical Path, along with its subsidiaries (collectively referred to herein as
the "Company") provides complete end-to-end Internet messaging and collaboration
solutions to corporations, Internet service providers, telecommunications
companies, web hosting companies and web portals.

  Acquisitions

     To date, business combinations have been accounted for under the purchase
method of accounting. The Company includes the results of operations of the
acquired business from the acquisition date. Net assets of the companies
acquired are recorded at their fair value at the acquisition date. The excess of
the purchase price over the fair value of net assets acquired is included in
goodwill and other purchased intangibles in the accompanying consolidated
balance sheet.

  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 consolidated financial statements include the accounts of the Company
and its wholly owned subsidiaries. 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 that are required as collateral for Company issued
credit cards.

  Investments

     The Company's marketable securities are classified as available-for-sale as
of the balance sheet date and are reported at fair value, with unrealized gains
and losses, net of tax, recorded in shareholders' equity. Realized gains or
losses and permanent declines in value, if any, on available-for-sale securities
will be reported in other income or expense as incurred. The Company uses the
cost method to account for certain non-marketable securities in which it has a
minority interest and does not exercise significant influence. The Company
periodically reviews these investments for other-than-temporary impairment.

  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
primarily located in the United States. The Company maintains reserves for
potential credit losses; historically, such losses have been within management's
expectations.

CRITICAL PATH, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     During the year ended December 31, 1998 and 1999, 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 Internet
messaging services to two customers. During the year ended December 31, 1999,
these two customers accounted for approximately 15% and 4% of net 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 and notes receivable, accounts payable and capital
lease obligations, are carried at cost, which approximates fair value due to the
short maturity of these instruments.

  Property and equipment

     Property and equipment are stated at cost less accumulated depreciation.
Depreciation 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. Gains and losses on disposals are included in income
at amounts equal to the difference between the net book value of the disposed
assets and the proceeds received upon disposal. Expenditures for replacements
and betterments are capitalized, while expenditures for maintenance and repairs
are charged against earnings as incurred.

  Internally developed software

     During 1999, the Company adopted Statement of Position ("SOP") 98-1,
"Accounting for the Costs of Computer Software Developed or Obtained for
Internal Use," which requires that certain costs for the development of internal
use software should be capitalized, including the costs of coding, software
configuration, upgrades and enhancements. The adoption of this pronouncement did
not have a material effect on the Company's financial results.

  Intangible assets

     Goodwill represents the excess of the purchase price paid over the fair
value of tangible and identifiable intangible net assets acquired in business
combinations. Identifiable intangible assets primarily include assembled
workforce, customer base, and existing technology. The Company uses modeling
techniques on new acquisitions and long-range business plans, revised annually,
to assess whether a revision of the existing estimated useful lives of
intangible assets is necessary. Intangible assets are stated net of accumulated
amortization and are amortized on a straight-line basis over their expected
useful lives ranging from two to eight years.

  Valuation of long-lived assets

     In accordance with Statement of Financial Accounting Standards ("SFAS") No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed Of," the Company periodically evaluates the carrying value
of long-lived assets and certain identifiable intangibles for impairment, when
events and circumstances indicate that the book value of an asset may not be
recoverable. An impairment loss is recognized whenever the review demonstrates
that the book value of a long-lived asset is not recoverable. Since February 19,
1997 (inception) through December 31, 1999, no impairment losses have been
identified.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

  Revenue recognition

     The Company derives most of its revenue through the sale of electronic
messaging services. Billings for such services are based either on contractual
rates per active mailbox per month, non-refundable fixed payments or 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.

     Revenues for software licenses for which collection of the resulting
receivable is deemed probable are recognized upon delivery of the product
provided there is persuasive evidence of an arrangement, the fee is fixed and
determinable, and the agreement does not require significant customization of
the software. Revenues from software maintenance are recognized ratably over the
maintenance term. Revenues from the Company's enhanced facsimile, long distance
and other services are recognized as the services are performed. Amounts billed
or received in advance of service delivery are recorded as deferred revenue.

  Research and development

     Research and development costs include expenses incurred by the Company to
develop and enhance its messaging service offerings and to develop new
electronic messaging services. Research and development costs, including
in-process research and development costs, are expensed as incurred.

  Advertising expense

     Advertising costs are expensed as incurred and totaled $0, $135,000 and
$414,000 during the period from February 19, 1997 (Inception) through December
31, 1997 and the years ended December 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 Stock Issued to Employees" and complies with the
disclosure provisions of SFAS No. 123, "Accounting for Stock-Based
Compensation." Under APB No. 25, compensation expense is based on the
difference, if any, on the date of the grant, between the fair value of the
Company's stock and the exercise price of the option. The Company accounts for
equity instruments issued to non-employees in accordance with the provisions of
SFAS No. 123 and Emerging Issues Task Force ("EITF") 96-18, "Accounting for
Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in
Conjunction with Selling, Goods or Services."

  Income taxes

     Income taxes are computed 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 consolidated 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 ("SAB") No. 98. Under the provisions of SFAS No. 128 and SAB No. 98,
basic net loss per share is computed by dividing the net loss available to
common shareholders for the period by the weighted average number of common
shares outstanding during the period, excluding shares subject to repurchase and
in escrow relative to acquisition. 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, shares held
in escrow, 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.

  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.

  Foreign currency translation

     Assets and liabilities recorded in foreign currencies are translated at the
exchange rate on the balance sheet date. Revenue and expenses are translated at
average rates of exchange prevailing during the year. Translation adjustments
resulting from this process are charged or credited to other comprehensive
income, a component of shareholders' equity. Gains and losses on foreign
currency transactions are included in "Interest and other expense, net."

  Segment and geographic 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. The
Company operates in one principal business segment across domestic and
international markets. Substantially all of the Company's operating results and
identifiable assets are in the United States.

  Reclassifications

     Certain amounts previously reported have been reclassified to conform to
the current period presentation.

  Recent accounting pronouncements

     In December 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin ("SAB") No. 101, "Revenue Recognition in Financial
Statements," which provides guidance on the recognition, presentation, and
disclosure of revenue in financial statements filed with the SEC. SAB No. 101
outlines the basic criteria that must be met to recognize revenue and provides
guidance for disclosures related to revenue recognition policies. Management
believes that the impact of SAB No. 101 will not have a material effect on the
financial position or results of operations of the Company.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities". SFAS
133 establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts

NOTE 3 -- ACQUISITION-RELATED RETENTION BONUS

     In connection with its acquisitions of dotOne, Amplitude, Xeti and FaxNet,
the Company established a retention bonus program in the aggregate amount of $14
million to provide incentive for former dotOne, Amplitude, Xeti and FaxNet
employees to continue their employment with Critical Path. Payment of bonuses to
the listed employees will occur one year following the date of acquisition,
unless the listed employees voluntarily terminate their employment with the
Company prior to the respective acquisition's one-year anniversary. The
aggregate amount of the eligible bonuses is adjusted downward at each point that
a former dotOne, Amplitude, and FaxNet employee chooses to terminate his or her
employment with the Company. The amount of any such downward adjustment
corresponds to the amount that the terminating employee would have received had
he or she elected to continue employment with the Company. A ratable share of
the adjusted eligible bonus amount will be accrued and charged to compensation
expense over the respective 12 months commencing on the date the bonuses are
granted. As of December 31, 1999, the aggregate, adjusted eligible bonus amount
was $10.6 million, and the ratable charge to compensation expense was $4.1
million. Based on the functions of the employees scheduled to receive
acquisition bonuses, $520,000 of the compensation charge was allocated to cost
of net revenues and the remaining $3.6 million was allocated to operating
expenses.

(see Note 2 -- "Acquisitions"), the Company has accrued for certain
acquisition-related costs in the amount of $10 million and $11 million,
respectively. Upon consummation of these acquisitions, the related amounts were

  Notes receivable

     In July 1999, the Company advanced $10 million to a privately-held company
pursuant to a promissory note. The note bears interest at the prime rate of
interest as stipulated in the Wall Street Journal. The amount was advanced in
connection with the Company's evaluation of the obligor for potential
acquisition. Under the terms of the note, all principal and accrued interest is
repayable within 90 days of written demand by the holder. Upon the decision by
Critical Path not to proceed with an acquisition of the obligor, Critical Path
presented a demand notice for repayment on August 18, 1999. All amounts owed to
Critical Path pursuant to this note were due to be paid not later than November
16, 1999, however, Critical Path granted an extension to the obligor. All
principal and interest was subsequently paid in January 2000.

     In August 1999, the Company advanced $5 million to docSpace pursuant to a
promissory note. The note bears interest at the prime rate of interest of 8.0%
per annum and matures on August 2, 2000. The amount was advanced in connection
with the Company's evaluation of docSpace for potential acquisition. Under the
terms of the note, any portion of the principal and/or interest outstanding on
the note may be converted into Common Stock at the election of docSpace. On
March 8, 2000, the Company consummated its acquisition of docSpace.

NOTE 11 -- INCOME TAXES

     The Company did not provide any current or deferred federal, state or
foreign income tax provision or benefit for any of the periods presented because
it has experienced operating losses since inception. The Company has provided a
full valuation allowance on the deferred net tax asset, consisting primarily of
net operating loss carryforwards, because of uncertainty regarding its
realizability

     At December 31, 1999, the Company had approximately $94.9 million 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 through 2019 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. These carryforwards will begin to expire
at various times starting in 2012 and 2005 for federal and state tax purposes,
respectively. To the extent that net operating loss carryforwards, when
realized, relate to stock option deductions of approximately $8.9 million, the
resulting benefits will be credited to shareholders' equity.

     At December 31, 1999, the Company also had research and development credit
carryforwards of approximately $1.2 million and $717,000 for federal and state
purposes, respectively. The research and development credit carryforwards expire
through 2019 for federal purposes, and do not expire for state purposes.

  Leases

     The Company leases office space and equipment under noncancelable operating
and capital leases with various expiration dates through 2004. Rent expense for
the period from February 19, 1997 (inception) to December 31, 1997 and for the
years ended December 31, 1998 and 1999, totaled $33,000, $220,000 and
$1,253,000, respectively.

     Certain lease agreements contain covenants, which, among other
restrictions, prohibit the Company with respect to changes in business without
prior written consent of the bank. The Company's acquisition of Amplitude (see
Note 2 -- "Acquisitions") triggered a change in business covenant violation of
the Amplitude's lease facility agreement acquired by the Company. The Company
has obtained a waiver from the bank for its violation and has amended the
underlying agreement so as to prevent future violations.

accruing at a rate of 6.3% per annum.

     In April 1998, the Company entered into another financing agreement that
provides for the acquisition of equipment up to $2,000,000. Amounts available
under this agreement are limited to specific acquisitions between May 1, 1998
and April 30, 1999. Such amounts are payable over a three-year period in monthly
installments of principal and interest, with interest accruing at the rate of
7.0% per annum. As part of this agreement, the Company issued warrants to
purchase 97,006 shares of Series A Preferred Stock at a purchase price of $0.72
per share. The Company estimated the fair value of these warrants at date of
issuance was approximately $53,000 that is being amortized as interest expense
over the term of the lease obligation.

     In May 1998, the Company entered into a financing agreement that provides
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 were
limited to specific acquisitions between March 1, 1998 and May 1, 1999. Such
amounts are payable over a three-year period in monthly installments of
principal and interest, with interest accruing at the rate of 7.0% per annum. As
part of this agreement, the Company issued warrants to purchase 242,516 shares
of Series A Preferred Stock at a purchase price of $0.72 per share. The Company
estimated the fair value associated with these warrants at date of issuance was
approximately $133,000 which is being amortized as interest expense over the
term of the lease obligation.

  Service Level Agreements

     Net revenues are derived from contractual relationships that typically have
one to three year terms. Certain agreements require minimum performance
standards regarding the availability and response time of email services. If
these standards are not met, such contracts are subject to termination and the
Company could be subject to monetary penalties.

  Contingencies

     The Company recently acquired The docSpace Company, which is involved in a
patent infringement action with Tumbleweed Communications Corp. The lawsuit
relates to a Tumbleweed patent that describes an apparatus for delivering
documents via the Internet. docSpace has denied the allegations of infringement,
and has counterclaimed for violations of the antitrust laws and related state
law claims. This case is in the preliminary phase and the Company is not
currently able to assess the impact, if any, on its financial position or
results of operations.

     The Company is party to various legal proceedings in the ordinary course of
its business. The Company believes that the ultimate outcome of these matters
will not have a material adverse impact on its financial position, results of
operations, or operating cash flow.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     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 net
proceeds of approximately $10,749,000. 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.

     Prior to the closing of the Company's initial public offering, the Series B
placement agent sold back to the Company at $4.26 per share an aggregate of
53,293 shares held by the placement agent or its affiliates.

     As of the closing of the Company's initial public offering, all of the
Preferred Stock outstanding was converted into an aggregate of 19,912,000 shares
of Common Stock at conversion ratio of 1:1.

  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.

     On March 29, 1999, the Company completed its initial public offering
(referred to herein as the "Offering") of 5,175,000 shares of Common Stock
(including the exercise of the underwriters over allotment option) and realized
net proceeds of $114.1 million.

     On June 2, 1999, the Company completed its secondary public offering of
3,000,000 shares of Common Stock and realized net proceeds of $140.7 million.

  Warrants

     In May 1998, the Company issued a warrant to purchase up to $250,000 of
Preferred Stock in the Company's next financing round to a customer as part of
an email services agreement. The warrant was exercisable until December 31, 2001
and the exercise price per share was equal to the price per share at which the
Company sold the Preferred Stock. In September 1998, the warrant was 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 and $48,000 was recognized in 1998 and 1999,
respectively.

     In connection with various financing agreements described in Note 10, the
Company issued warrants to purchase 339,522 shares 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. The total amount of related warrants were exercised in
September and October of 1999.

     In connection with the issuance of certain convertible promissory notes
described in Note 10, 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 that was being amortized as interest expense during 1998 through March
of 1999 at which time the remaining warrants to purchase 223,110 share of Series
A were exercised.

     In connection with the Series B financings, the Company issued warrants to
purchase 121,654 shares of Series B at $4.26 per share to the placement agent.
The total amount of warrants was exercised in March 1999.

     In January 1999, the Company entered into an agreement with ICQ, Inc., a
subsidiary of America Online, Inc., pursuant to which the Company provides email

ICQ agreed to provide sub-branded advertising for the Company in exchange for a

</TABLE>

     In the quarter ended June 30, 1999, the Company amended the vesting terms
of the agreement with ICQ. The revised vesting terms did not impact the shares
underlying the first milestone, which vested immediately upon the execution of
the agreement. The shares underlying each of the remaining milestones vest on
the date in a quarter in which ICQ completes a minimum registration of 100,000
sub-branded ICQ mailboxes, compared to 250,000 sub-branded ICQ mailboxes as
provided in the terms of the original agreement. The amended agreement also
provides that only one milestone may be achieved on a quarterly basis. The
Company believes it is probable that all milestones will be achieved.

     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 are remeasured at each
subsequent reporting date until each sub-branded ICQ mailbox registration
threshold is achieved and the related warrant shares vest, at which time the
fair value attributable to that tranche of the warrant is fixed. In the event
such remeasurement results in increases or decreases from the initial fair
value, which could be substantial, these increases or decreases will be
recognized immediately, if the fair value of the shares underlying the milestone
has been previously recognized, or over the remaining term, if not.

     As of December 31, 1999, three of the five milestones had been attained.
Aggregate charges to stock-based expenses of $9.2 million were recorded during
1999 related to these warrants. The remaining shares underlying the fourth and
fifth milestones were remeasured using the December 31, 1999 closing price of
$94.38 resulting in a revised fair value of the warrant of $109.7 million. The
Company expects that future changes in the trading price of the Company's Common
Stock at the end of each quarter, and at the time certain milestones are
achieved, will cause additional substantial changes in the ultimate amount of
the related stock-based charges.

  Qwest Communications Corporation

     In October 1999, the Company entered into an agreement with Qwest
Communications Corporation, a telecommunications company, pursuant to which the
Company will provide email hosting services to Qwest's customers. As part of the
agreement, Qwest agreed to provide sub-branded advertising for Critical Path in
exchange for a warrant to purchase up to a maximum of 3,534,540 shares of Common
Stock upon attainment of each of six milestones. The Company believes that this
agreement could have a significant current and

     The shares underlying those milestones for which achievement is considered
probable are remeasured at each subsequent reporting date, beginning at December
31, 1999, until each sub-branded Qwest mailbox registration threshold is
achieved and the related warrant shares vest, at which time the fair value
attributable to that tranche of the warrant is fixed. In the event such
remeasurement results in increases or decreases from the initial fair value,
which could be substantial, these increases or decreases will be recognized
immediately, if the fair value of the shares underlying the milestone has been
previously recognized, or over the remaining term, if not.

     Using the Black-Scholes option-pricing model and assuming a term of 5 years
and expected volatility of 90%, the initial fair value of the warrants
associated with the first milestone approximated $22.2 million, which is being
amortized to advertising expense using the straight-line method over 3 years.
The Company expects that future changes in the trading price of the Company's
Common Stock at the end of each quarter, and at the time certain milestones are
considered probable and achieved, may cause additional substantial changes in
the ultimate amount of the related stock-based charges.

  Worldsport Network Ltd.

     In December 1999, the Company entered into an agreement with Worldsport
Network Ltd., the sole and exclusive provider of Internet solutions for the
General Association of International Sports Federations ("GAISF") and a majority
of the international federations it recognizes. Worldsport will offer Critical
Path's advanced Web-based email and calendaring services to the entire GAISF
network and its members. As part of the agreement, Worldsport agreed to provide
sub-branded advertising for the Company in exchange for warrants to purchase up
to a 1.25% equity interest in the Company on a fully diluted basis upon
attainment of each of five milestones based on the number of email boxes
Worldsport registers and provides sub-branding. The warrants are exercisable for
five years after becoming vested. Any warrants not vested within five years of
the date of the agreement will be cancelled. The Company believes that this

     The shares underlying those milestones for which achievement is considered

remeasurement results in increases or decreases from the initial fair value,
which could be substantial, these increases or decreases will be recognized
immediately, if the fair value of the shares underlying the milestone has been
previously recognized, or over the remaining term, if not.

     As of December 31, 1999, none of the milestones were considered probable
and as a result, no deferred compensation associated with these warrants was
recognized. The Company expects that future changes in the trading price of the
Company's Common Stock at the end of each quarter, and at the time subsequent
milestones are considered probable and achieved, will cause additional
substantial changes in the ultimate amount of the related stock-based expenses.

  Lessor Warrant

     In December 1999, the Company entered into an agreement with one of its
lessors, in connection with an office lease, pursuant to which the lessor is
entitled to purchase up to a maximum of 25,000 shares of Common Stock. The
warrants may be exercised beginning January 1, 2000 through December 20, 2006 at
a price of $90.00 per share. The warrants vest at the beginning of each month on
a straight-line basis in the amount of 521 shares per month.

     Using the Black-Scholes option pricing model and assuming a term of 6 years
and expected volatility of 90%, the fair value of the warrants on the effective
date of the agreement approximated $2.0 million, which will be amortized to
general and administrative expenses using the straight-line method over 10 years
beginning January 2000.

  AT&T

     In January 2000, the docSpace Company entered into an agreement with AT&T
Corporation, pursuant to which the docSpace Company will provide secure
messaging services to AT&T's Internet portal customers. As part of the
agreement, AT&T agreed to provide marketing, publicity, promotional and
provision branding for docSpace, and upon completion of the acquisition for
Critical Path, in exchange for a warrant to purchase up to a maximum of 349,123
shares of Common Stock upon attainment of each of three milestones. The Company

     The Company believes that all shares underlying these warrants are
considered probable of issuance. The shares underlying the warrants associated
with the first milestone were fully vested on the inception date of the
agreement. The shares underlying the remaining warrants associated with the
second and third milestone will be remeasured at each subsequent reporting date,
beginning at March 31, 2000, until each sub-branded AT&T mailbox registration
threshold is achieved and the related warrant shares vest, at which time the
fair value attributable to that tranche of the warrant is fixed. In the event
such remeasurement results in increases or decreases from the initial fair
value, which could be substantial, these increases or decreases will be
recognized immediately, if the fair value of the shares underlying the milestone
has been previously recognized, or over the remaining term, if not. The Company
expects that future changes in the trading price of the Company's Common Stock
at the end of each quarter, and at the time certain milestones are achieved,
will cause additional substantial changes in the ultimate amount of the related
stock-based charges.

     Using the Black-Scholes option-pricing model and assuming a term of 7 years
and expected volatility of 90%, the initial fair value of all the warrants on
the effective date of the agreement approximated $26.4 million, which is
included as a component of the purchase price of the acquisition. The warrants
underlying the second and third milestones will be remeasured at each subsequent
reporting date until the milestone requirements are met. The remeasured amounts
will be capitalized and amortized to expense using the straight-line method over
3 years.

     The Company expects that future changes in the trading price of the
Company's Common Stock at the end of each quarter, and at the time certain
milestones are achieved, will cause additional substantial changes in the
ultimate amount of the related stock-based charges.

  Stock Purchase Rights

     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. These
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 the Offering, repurchase rights
with respect to 50% of the then unvested shares of Common Stock will lapse. On
September 1, 1999, 80,508 shares were repurchased in connection with the early
termination of one of the founders. At December 31, 1998 and 1999, 2,130,680 and
1,155,303 of these shares of Common Stock were subject to repurchase rights,
respectively. In connection with the issuance of these shares, the Company
recorded unearned compensation of $1,306,000 that is being recognized over the
periods in which the Company's repurchase rights lapse.

     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 was equal to 80%
of the price at which the Preferred Stock was 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 estimated the fair value of the purchase right to be $194,000, which
is recognized as a sales discount over the term of the services agreement.
Approximately $136,000 and $58,000 was recognized in 1998 and 1999,
respectively. No warrants were exercised as of December 31, 1998. In January
1999, the customer exercised stock purchase rights to purchase 454,544 shares of
Series B for cash proceeds of approximately $1,744,000.

     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 and 1999, 1,221,575 and 902,903 of these
shares of Common Stock were subject to repurchase rights, respectively. In
connection with the option grant preceding this transaction, the Company
recognized unearned compensation totaling $3.8 million that is included in the
aggregate unearned compensation charges discussed below.

  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 Company's
Offering. The Purchase Plan reserves 600,000 shares for issuance thereunder.
Employees generally will be eligible to participate in the Purchase Plan if the
Company customarily employs them 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 beginning on the effective date of the Offering with subsequent
offering periods beginning 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 purchases under the Purchase Plan were 42,495 in 1999. The estimated
weighted average fair value of those purchase was $11.00 per share in 1999. The
Company based its estimates on the Black-Scholes model using the following
assumption: risk-free weighted average interest rate of 6.0%, volatility factor
of expected market price of the Company's Common Stock of 90.0%, and expected
life of 90 days.

  Stock Options

     In January 1998, the Company's Board of Directors adopted the 1998 Stock
Option Plan ("1998 Plan"). The 1998 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 ("ISOs") or
nonqualified stock options ("NSOs"). ISOs may be granted only to Company
employees (including officers and directors). NSOs may be granted to Company
employees and consultants. In September 1999, the Company's Board of Directors
adopted the 1999 Stock Option Plan ("1999 Plan"). The 1999 Plan provides for the
granting of up to 4.0 million NSOs options to employees, directors, and
consultants.

     The Company has, in connection with the acquisition of various companies,
assumed the stock option plans of each acquired company. At December 31, 1999, a
total of 830,672 shares of the Company's Common Stock were reserved for
outstanding shares issued under the assumed plans, and the related options are
included in the following table.

     Options under all of the Company's stock option plans 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 years ended December 31, 1998 and 1999, the Company recognized
unearned compensation totaling $19.9 million and $22.3 million respectively,
which is being amortized over the vesting periods of the related options.
Amortization expense recognized during 1998 and 1999 totaled approximately $2.5
million, and $17.6 million, respectively.

     During 1999, the Company also incurred a stock-based charge of
approximately $2 million in connection with a severance agreement for a
terminated employee. This expense was charged to cost of net revenues.

the form attached hereto as Exhibit A (the "Voting Agreement").

        D. A portion of the shares of Parent Common Stock otherwise issuable by
Parent in connection with the Merger shall be placed in escrow by Parent, the

        1.1 The Merger. At the Effective Time (as defined in Section 1.2) and
subject to and upon the terms and conditions of this Agreement and the
applicable provisions of the Delaware General Corporation Law (the "DGCL"),
Merger Sub shall be merged with and into the Company, the separate corporate
existence of Merger Sub shall cease and the Company shall continue as the
surviving corporation and as a wholly owned subsidiary of Parent. The Company,
as the surviving corporation after the Merger is hereinafter sometimes referred
to as the "Surviving Corporation".

        1.2 Effective Time. Unless this Agreement is earlier terminated pursuant
to Section 8.1, the closing of the Merger (the "Closing") will take place as
promptly as practicable, but no later than two (2) business days, following
satisfaction or waiver of the conditions set forth in Article VI, at the offices
of Wilson Sonsini Goodrich & Rosati, 650 Page Mill Road, Palo Alto, California,
unless another place or time is agreed to by Parent and the Company. The date
upon which the Closing actually occurs is herein referred to as the "Closing
Date". On the Closing Date, the parties hereto shall cause the Merger to be
consummated by filing an Agreement of Merger with the California Secretary of
State (the "Agreement of Merger"), a form of which is attached hereto, in
accordance with the relevant provisions of applicable law. The date and time the
Merger becomes effective in accordance with the provisions of the DGCL is the
"Effective Time".

        1.3 Effect of the Merger. At the Effective Time, the effect of the
Merger shall be as provided in the applicable provisions of the DGCL. Without
limiting the generality of the foregoing, and subject thereto, at the Effective
Time, all the property, rights, privileges, powers and franchises of the Company
and Merger Sub shall vest in the Surviving Corporation, and all debts,
liabilities and duties of the Company and Merger Sub shall become the debts,
liabilities and duties of the Surviving Corporation.

        1.4 Certificate of Incorporation; Bylaws.

               (a) Unless otherwise determined by Parent prior to the Effective
Time, at the Effective Time, the Certificate of Incorporation of Merger Sub
shall be the Certificate of Incorporation of the Surviving Corporation until
thereafter amended as provided by law and such Certificate of Incorporation.

               (b) The Bylaws of Merger Sub, as in effect immediately prior to
the Effective Time, shall be the Bylaws of the Surviving Corporation until
thereafter amended.

        1.5 Directors and Officers. The director(s) of Merger Sub immediately
prior to the Effective Time shall be the initial director(s) of the Surviving
Corporation, each to hold office in accordance with the Certificate of
Incorporation and Bylaws of the Surviving Corporation. The officers of Merger
Sub immediately prior to the Effective Time shall be the initial officers of the



                                      -2-
<PAGE>   4

Surviving Corporation, each to hold office in accordance with the Bylaws of the
Surviving Corporation.

        1.6 Shares to Be Issued; Effect on Capital Stock. The aggregate number
of shares of Parent Common Stock to be issued (including Parent Common Stock to
be reserved for issuance upon exercise of any of the Company's options to be
assumed by Parent) in exchange for the acquisition by Parent of all outstanding
Company Capital Stock and all unexpired and unexercised options to acquire
Company Capital Stock shall be 3,982,930 (the "Stock Consideration"). No
adjustment shall be made in the number of shares of Parent Common Stock issued
in the Merger as a result of any cash proceeds received by the Company from the
date hereof to the Closing Date pursuant to the exercise of options to acquire
Company Capital Stock. Subject to the terms and conditions of this Agreement, as
of the Effective Time, by virtue of the Merger and without any action on the
part of Merger Sub, the Company or the holder of any shares of the Company
Capital Stock, the following shall occur:

               (a) Conversion of Company Common Stock. Each share of Common
Stock of the Company ("Company Common Stock") issued and outstanding immediately
prior to the Effective Time (other than any shares of Company Common Stock to be
canceled pursuant to Section 1.6(c) and any Dissenting Shares (as defined and to
the extent provided in Section 1.7(a)) will be canceled and extinguished and be
converted automatically into that number of shares of Parent Common Stock as is
equal to the Exchange Ratio (as defined in paragraph (h) below).

               (b) Conversion of Company Preferred Stock. Each share of Series A
Preferred Stock of the Company ("Series A Preferred") and Series B Preferred
Stock of the Company ("Series B Preferred", and together with the Series A
Preferred, the "Company Preferred") issued and outstanding immediately prior to
the Effective Time (other than any shares of Company Preferred that are
converted into shares of Company Common Stock immediately prior to the Effective
Time, any shares of Company Preferred to be canceled pursuant to Section 1.6(c)
and any Dissenting Shares (as defined and to the extent provided in Section
1.7(a)) will be canceled and extinguished and be converted automatically into
that number of shares of Parent Common Stock as is equal to the Exchange Ratio
(as defined in paragraph (h) below) multiplied by the number of shares of
Company Common Stock into which such share of Company Preferred would convert
pursuant to an automatic conversion as described in the Company's Certificate of
Incorporation.

               (c) Cancellation of Parent-Owned and Company-Owned Stock. Each
share of Company Capital Stock owned by Merger Sub, Parent, the Company or any
direct or indirect wholly-owned subsidiary of Parent or of the Company
immediately prior to the Effective Time shall be canceled and extinguished
without any conversion thereof.

               (d) Stock Options. At the Effective Time, all options to purchase
Company Common Stock then outstanding under the Company's 1998 Stock Plan (the
"Option Plan"), or otherwise, shall be assumed by Parent in accordance with
provisions described below.



                                      -3-
<PAGE>   5





                        (i) At the Effective Time, each outstanding option to
purchase shares of Company Common Stock (each a "Company Option") under the
Option Plan or otherwise, whether vested or unvested, shall be, in connection
with the Merger, assumed by Parent. Each Company Option so assumed by Parent
under this Agreement shall continue to have, and be subject to, the same terms
and conditions set forth in the Option Plan and/or as provided in the respective
option agreements governing such Company Option immediately prior to the
Effective Time, except that (A) such Company Option shall be exercisable for
that number of whole shares of Parent Common Stock equal to the product of the
number of shares of Company Common Stock that were issuable upon exercise of
such Company Option immediately prior to the Effective Time multiplied by the
Exchange Ratio (as defined in paragraph (h) below), rounded down to the nearest
whole number of shares of Parent Common Stock and (B) the per share exercise
price for the shares of Parent Common Stock issuable upon exercise of such
assumed Company Option shall be equal to the quotient determined by dividing the
exercise price per share of Company Common Stock at which such Company Option
was exercisable immediately prior to the Effective Time by the Exchange Ratio,
rounded up to the nearest whole cent.

                        (ii) It is the intention of the parties that the Company
Options assumed by Parent qualify following the Effective Time as incentive
stock options as defined in Section 422 of the Code to the extent the Company
Options qualified as incentive stock options immediately prior to the Effective
Time.

                        (iii) Promptly following the Effective Time, Parent will
issue to each holder of an outstanding Company Option a document evidencing the
foregoing assumption of such Company Option by Parent.

               (e) Capital Stock of Merger Sub. Each share of Common Stock of
Merger Sub issued and outstanding immediately prior to the Effective Time shall
be converted into and exchanged for one validly issued, fully paid and
nonassessable share of Common Stock of the Surviving Corporation. Each stock
certificate of Merger Sub evidencing ownership of any such shares shall continue
to evidence ownership of such shares of capital stock of the Surviving
Corporation.

               (f) Adjustments to Exchange Ratio. The Exchange Ratio shall be
adjusted to reflect fully the effect of any stock split, reverse split, stock
dividend (including any dividend or distribution of securities convertible into
Parent Common Stock or Company Capital Stock), reorganization, recapitalization
or other like change with respect to Parent Common Stock or Company Capital
Stock occurring or with a record date after the date hereof and prior to the
Effective Time.

               (g) Fractional Shares. No fraction of a share of Parent Common
Stock will be issued, but in lieu thereof, each holder of shares of Company
Capital Stock who would otherwise be entitled to a fraction of a share of Parent
Common Stock (after aggregating all fractional shares of Parent Common Stock to
be received by such holder) shall be entitled to receive from Parent an amount
of cash (rounded down to the nearest whole cent) equal to the product of (i)
such fraction,


                                      -4-
<PAGE>   6

               multiplied by (ii) the average closing price of a share of Parent
Common Stock for the ten (10) consecutive trading days ending on the second
trading day immediately prior to the Closing, as reported on the Nasdaq National
Market.

               (h) Definitions.

                        (i) Escrow Consideration. The "Escrow Consideration"
shall mean 0.2 multiplied by the Stock Consideration.

                        (ii) Exchange Ratio. The "Exchange Ratio" shall mean the
Stock Consideration divided by the Outstanding Aggregate Amount.

                        (iii) Outstanding Aggregate Amount. The "Outstanding
Aggregate Amount" shall mean the sum of the Outstanding Common Amount and the
Outstanding Option Amount.

                        (iv) Outstanding Common Amount. The "Outstanding Common
Amount" shall mean the aggregate number of shares of Company Common Stock
outstanding on the date hereof (treating all shares of outstanding Company
Preferred Stock and the Comdisco Rights (as defined herein) as automatically
converting into Company Common Stock as of such time).

                        (v) Outstanding Option Amount. The "Outstanding Option
Amount" shall mean the aggregate number of shares of Company Common Stock
issuable upon the exercise of all outstanding options to acquire shares of
Company Common Stock on the date hereof.

        1.7 Dissenting Shares.

               (a) Notwithstanding any provision of this Agreement to the
contrary, any shares of Company Capital Stock held by a holder who has demanded
and perfected appraisal or dissenters' rights for such shares in accordance with
the DGCL and who, as of the Effective Time, has not effectively withdrawn or
lost such appraisal or dissenters' rights ("Dissenting Shares"), shall not be
converted into or represent Parent Common Stock pursuant to Section 1.6, but the
holder thereof shall only be entitled to such rights as are granted by the DGCL.

               (b) Notwithstanding the provisions of subsection (a), if any
holder of shares of Company Capital Stock who demands appraisal of such shares
under the DGCL shall effectively withdraw or lose (through failure to perfect or
otherwise) the right to appraisal, then, as of the later of the Effective Time
and the occurrence of such event, such holder's shares shall automatically be
converted into and represent only Parent Common Stock, such holder's portion of
the Cash Consideration Amount and cash in lieu of fractional shares as provided
in Section 1.6, without interest thereon.

               (c) The Company shall give Parent (i) prompt notice of any
written demands for appraisal of any shares of Company Capital Stock,
withdrawals of such demands, and any other




                                      -5-
<PAGE>   7

instruments served pursuant to the DGCL and received by the Company and (ii) the
opportunity to participate in all negotiations and proceedings with respect to
demands for appraisal under the DGCL. The Company shall not, except with the
prior written consent of Parent, voluntarily make any payment with respect to
any demands for appraisal of capital stock of the Company or offer to settle or
settle any such demands.

        1.8 Surrender of Certificates.

               (a) Exchange Agent. Prior to the Effective Time, Parent shall
designate a bank or trust company reasonably acceptable to the Company to act as
exchange agent (the "Exchange Agent") in the Merger.

               (b) Parent to Provide Common Stock. Promptly after the Effective
Time, Parent shall make available to the Exchange Agent for exchange in
accordance with this Article I, the aggregate number of shares of Parent Common
Stock issuable pursuant to Section 1.6 in exchange for outstanding shares of
Company Capital Stock; provided that on behalf of the holders of Company Capital
Stock, Parent shall deposit into an escrow account a number of shares of Parent
Common Stock equal to the Escrow Amount out of the Stock Consideration otherwise
issuable pursuant to Section 1.6. The portion of the Escrow Amount contributed
on behalf of each holder of Company Capital Stock (other than holders of
Dissenting Shares on whose behalf no shares will be deposited into the escrow
account) shall be in proportion to the aggregate number of shares of Parent
Common Stock which such holder would otherwise be entitled to receive under
Section 1.6 by virtue of ownership of outstanding shares of Company Capital
Stock.

               (c) Exchange Procedures. Promptly after the Effective Time,
Parent shall cause to be mailed to each holder of record of a certificate or
certificates (the "Certificates") which immediately prior to the Effective Time
represented outstanding shares of Company Capital Stock whose shares were
converted into shares of Parent Common Stock pursuant to Section 1.6, (i) a
letter of transmittal (which shall specify that delivery shall be effected, and
risk of loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Exchange Agent and shall be in such form and have such other
provisions as Parent may reasonably specify) and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for certificates
representing shares of Parent Common Stock. Upon surrender of a Certificate for
cancellation to the Exchange Agent or to such other agent or agents as may be
appointed by Parent, together with such letter of transmittal, duly completed
and validly executed in accordance with the instructions thereto, the holder of
such Certificate shall be entitled to receive in exchange therefor a certificate
representing the number of whole shares of Parent Common Stock (less the number
of shares of Parent Common Stock, if any, to be deposited in the Escrow Fund (as
defined in Section 7.5 below) on such holder's behalf pursuant to Section 7.5
hereof), plus cash in lieu of fractional shares in accordance with Section 1.6,
to which such holder is entitled pursuant to Section 1.6, and the Certificate so
surrendered shall forthwith be canceled. As soon as practicable after the
Effective Time, and subject to and in accordance with the provisions of Article
VII hereof, Parent shall cause to be distributed to the Escrow Agent a
certificate or certificates representing that number of shares of Parent Common


                                      -6-
<PAGE>   8

Stock equal to the Escrow Amount which shall be registered in the name of the
Escrow Agent. Notwithstanding the provisions contained in Section 1.6(g), any
fractional share that would otherwise result from the issuance of a certificate
representing the shares of Parent Common Stock to be deposited into escrow
pursuant to Article VII hereof shall be rounded down to the nearest whole share
and any fraction of a share that would otherwise result from the issuance of a
certificate representing the remaining shares of Parent Common Stock which each
such shareholder would otherwise be entitled to receive under Section 1 by
virtue of ownership of outstanding shares of Company Common Stock shall be
rounded up to the nearest whole share. Such shares shall be owned beneficially
and of record by the holders on whose behalf such shares were deposited in the
Escrow Fund and shall be available to compensate Parent as provided in Article
VII. Until so surrendered, each outstanding Certificate that, prior to the
Effective Time, represented shares of Company Capital Stock will be deemed from
and after the Effective Time, for all corporate purposes, other than the payment
of dividends, to evidence the ownership of the number of full shares of Parent
Common Stock into which such shares of Company Capital Stock shall have been so
converted and the right to receive an amount in cash in lieu of the issuance of
any fractional shares in accordance with Section 1.6. Parent shall use its
reasonable efforts to cause the Exchange Agent to issue to each Company
stockholder the Parent Common Stock pursuant to Section 1.6 within 5 business
days after the Exchange Agent receives all documents necessary to effect such
exchange, properly completed, guaranteed and presented for transfer, from each
such Stockholder.

               (d) Distributions With Respect to Unexchanged Shares. No
dividends or other distributions declared or made after the Effective Time with
respect to Parent Common Stock with a record date after the Effective Time will
be paid to the holder of any unsurrendered Certificate with respect to the
shares of Parent Common Stock represented thereby until the holder of record of
such Certificate shall surrender such Certificate. Subject to applicable law,
following surrender of any such Certificate, there shall be paid to the record
holder of the certificates representing whole shares of Parent Common Stock
issued in exchange therefor, without interest, at the time of such surrender,
the amount of dividends or other distributions with a record date after the
Effective Time theretofore paid with respect to such whole shares of Parent
Common Stock.

               (e) Transfers of Ownership. If any certificate for shares of
Parent Common Stock is to be issued in a name other than that in which the
Certificate surrendered in exchange therefor is registered, it will be a
condition of the issuance thereof that the Certificate so surrendered will be
properly endorsed and otherwise in proper form for transfer and that the person
requesting such exchange will have paid to Parent or any agent designated by it
any transfer or other taxes required by reason of the issuance of a certificate
for shares of Parent Common Stock in any name other than that of the registered
holder of the Certificate surrendered, or established to the satisfaction of
Parent or any agent designated by it that such tax has been paid or is not
payable.

               (f) No Liability. Notwithstanding anything to the contrary in
this Section 1.8, none of the Exchange Agent, the Surviving Corporation or any
party hereto shall be liable to a holder of shares of Parent Common Stock or
Company Capital Stock for any amount properly paid to a public official pursuant
to any applicable abandoned property, escheat or similar law.




                                      -7-
<PAGE>   9

        1.9 No Further Ownership Rights in Company Capital Stock. All shares of
Parent Common Stock issued upon the surrender for exchange of shares of Company
Capital Stock in accordance with the terms hereof (including any cash paid in
respect thereof) shall be deemed to have been issued in full satisfaction of all
rights pertaining to such shares of Company Capital Stock, and there shall be no
further registration of transfers on the records of the Surviving Corporation of
shares of Company Capital Stock which were outstanding immediately prior to the
Effective Time. If, after the Effective Time, Certificates are presented to the
Surviving Corporation for any reason, they shall be canceled and exchanged as
provided in this Article I.

        1.10 Lost, Stolen or Destroyed Certificates. In the event any
certificates evidencing shares of Company Capital Stock shall have been lost,
stolen or destroyed, the Exchange Agent shall issue in exchange for such lost,
stolen or destroyed certificates, upon the making of an affidavit of that fact
by the holder thereof, such shares of Parent Common Stock and cash for
fractional shares, if any, as may be required pursuant to Section 1.6; provided,
however, that Parent may, in its discretion and as a condition precedent to the
issuance thereof, require the owner of such lost, stolen or destroyed
certificates to deliver a bond in such sum as it may reasonably direct as
indemnity against any claim that may be made against Parent or the Exchange
Agent with respect to the certificates alleged to have been lost, stolen or
destroyed.

        1.11 Tax and Accounting Consequences. It is intended by the parties
hereto that the Merger shall (i) constitute a reorganization within the meaning
of Section 368 of the Internal Revenue Code of 1986, as amended (the "Code") and
(ii) be accounted for financial reporting purposes as a purchase. The parties to
this Agreement hereby adopt this Agreement as a "plan of reorganization" within
the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Treasury
Regulations. No party to this Agreement shall take any action inconsistent with
such treatment.

        1.12 Taking of Necessary Action; Further Action. If, at any time after
the Effective Time, any such further action is necessary or desirable to carry
out the purposes of this Agreement and to vest the Surviving Corporation with
full right, title and possession to all assets, property, rights, privileges,
powers and franchises of the Company and Merger Sub, the officers and directors
of the Company and Merger Sub are fully authorized in the name of their
respective corporations or otherwise to take, and will take, all such lawful and
necessary action.

which it is bound obligating the Parent to grant, extend, accelerate the vesting
of, change the price of, otherwise amend or enter into any such option, warrant,
call, right, commitment or agreement.

registration statements filed by it with the U.S. Securities and Exchange
Commission (the "SEC") for all periods subsequent to March 31, 1999, all in the
form so filed (all of the foregoing being collectively referred to as the "SEC
Documents"). As of their respective filing dates, the SEC Documents complied in
all material respects with the requirements of the Exchange Act, and none of the
SEC Documents contained any untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements made therein not misleading, except to the extent corrected by a
subsequently filed document with the SEC. The financial statements of Parent,
including the notes thereto, included in the SEC Documents (the "Parent
Financial Statements") comply as to form in all material respects with
applicable accounting requirements and with the published rules and regulations
of the SEC with respect thereto, have been prepared in accordance with generally
accepted accounting principles consistently applied (except as may be indicated
in the notes thereto) and present fairly the consolidated financial position of
Parent at the dates thereof and of its

operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal audit adjustments).

        3.5 Merger Sub. Merger Sub has been formed solely for the purpose of
executing and delivering this Agreement and consummating the transactions
contemplated hereby. Since the date of its incorporation, Merger Sub has neither
engaged in or transacted any business or activity of any nature whatsoever other
than activities related to its corporate organization and the execution and
delivery of this Agreement. Merger Sub has no assets or properties or debts,
liabilities or obligations of any kind whatsoever, and other than this
Agreement, is not a party to any contract, agreement or undertaking of any
nature. The authorized capital stock of Merger Sub consists of 1,000 shares of
Merger Sub Common Stock, of which 1,000 shares are issued and outstanding. All
of the issued and outstanding shares of Merger Sub Common Stock are owned of
record and beneficially by Parent, free and clear of any encumbrance.

                              ADDITIONAL AGREEMENTS

        5.1 California Permit; Stockholder Meeting.

               (a) As promptly as practicable (and in any event within ten
business days) after the execution of this Agreement, Parent shall prepare the
necessary documents and Parent shall apply to obtain a permit (a "California
Permit") from the California Commissioner of Corporations (after a hearing
before such Department) pursuant to Section 25121 of the California Corporate
Securities Law of 1968, so that the issuance of the Parent Common Stock in the
Merger shall be exempt from registration under the Securities Act of 1933, as
amended (the "Securities Act"), by virtue of the exemption from registration
contained in Section 3(a)(10) thereof. The Company shall cooperate with, and
provide information to, Parent in connection with Parent's application for the
California Permit and shall prepare an information statement to be mailed to the
Company's stockholders concurrently with the notice of any hearing. The Company
and Parent will respond to any comments from the California Commissioner of
Corporations and use their reasonable best efforts to have the California Permit
granted as soon as practicable after such filing. As promptly as practicable
after the date of this Agreement, Parent shall prepare and make such filings as
are required under applicable Blue Sky laws relating to the transactions
contemplated by this Agreement.

               (b) As promptly as practicable after the receipt of a California
Permit, the Company shall submit this Agreement and the transactions
contemplated hereby, including without limitation the Merger, to the Company
stockholders for approval and adoption as provided by the DGCL and the Company's
Certificate of Incorporation and Bylaws. The information submitted to the
Company's stockholders shall be subject to review and approval by Parent and
shall include


                                      -32-
<PAGE>   34

information regarding the Company, the terms of the Merger and this Agreement
and, subject to Section 5.2 (c) hereof, the unanimous recommendation of the
Board of Directors of the Company in favor of the Merger, this Agreement and the
transactions contemplated hereby.

               (c) Nothing in this Agreement shall prevent the Board of
Directors of the Company from withholding, withdrawing, amending or modifying
its recommendation in favor of the Merger if (i) a Superior Offer (as defined
below) is made to the Company and is not withdrawn, (ii) neither the Company nor
any of its representatives shall have violated any of the restrictions set forth
in Section 4.2, and (iii) the Board of Directors of the Company concludes in
good faith, after consultation with its outside counsel, that, in light of such
Superior Offer, the withholding, withdrawal, amendment or modification of such
recommendation is required in order for the Board of Directors of the Company to
comply with its fiduciary obligations to the Company and the Company's
shareholders under applicable law. Nothing contained in this Section 5.1 shall
limit the Company's obligation to hold and convene the Company Stockholders'
Meeting (regardless of whether the recommendation of the Board of Directors of
the Company shall have been withdrawn, amended or modified). For purposes of
this Agreement, "Superior Offer" shall mean an unsolicited, bona fide written
offer made by a third party to consummate any of the following transactions: (i)
a merger, consolidation, business combination, recapitalization, liquidation,
dissolution or similar transaction involving the Company pursuant to which the
shareholders of the Company immediately preceding such transaction hold less
than 51% of the equity interest in the surviving or resulting entity of such
transaction; (ii) a sale or other disposition by the Company of assets
(excluding inventory and used equipment sold in the ordinary course of business)
representing in excess of 50% of the fair market value of the Company's business
immediately prior to such sale, or (iii) the acquisition by any person or group
(including by way of a tender offer or an exchange offer or issuance by the
Company), directly or indirectly, of beneficial ownership or a right to acquire
beneficial ownership of shares representing in excess of 50% of the voting power
of the then outstanding shares of capital stock of the Company, in each case on
terms that the Board of Directors of the Company determines, in its reasonable
judgment (based on a written opinion of an investment bank of nationally
recognized reputation) to be more favorable to the Company shareholders from a
financial point of view than the terms of the Merger and the consideration of
which reasonably likely exceeds the value of the consideration in the Merger
(after taking into account all relevant factors, including any conditions to the
Superior Offer, the timing of the consummation of the transaction pursuant to
the Superior Offer, the risk of nonconsummation thereof and the need for any
required governmental or other consents, filings and approvals); provided,
however, that any such offer shall not be deemed to be a "Superior Offer" if any
financing required to consummate the transaction contemplated by such offer is
not committed.

               (d) If for any reason the California Permit is not issued or if
the exemption provided by Section 3(a)(10) of the Securities Act is not
available with respect to the issuance of the Parent Common Stock in connection
with the Merger, then Parent shall as soon as practicable (and in any event
within five (5) business days of receiving all necessary financial statements
and accountant consents), prepare and file with the SEC a Form S-4 Registration
Statement (the "Form S-4 Registration Statement") with respect to the issuance
of the Parent Common Stock in connection



                                      -33-
<PAGE>   35

with the Merger. Each of the Company and Parent shall use all reasonable efforts
to have the Form S-4 Registration Statement declared effective under the
Securities Act as promptly as practicable after such filing. The Company will
use its reasonable efforts to cause the proxy statement included in the Form S-4
Registration Statement to be mailed to the Company's stockholders as promptly as
practicable after the Form S-4 Registration Statement is declared effective
under the Securities Act, and to call and hold a meeting of the Company's
stockholders to vote on a proposal to adopt and approve this Agreement and the
transactions contemplated hereby, including without limitation the Merger.

               (e) If for any reason the California Permit is issued, but is not
available for a limited number of stockholders of the Company, the Parent shall
grant registration rights to such effected stockholders on a pari passu basis
(as to rights and timely filing) with the shareholders of the Parent's Common
Stock who were issued such shares in a transaction contemplated under Rule 145
promulgated under the Securities Act of 1933, as amended.

        5.2 Access to Information. Subject to any applicable contractual
confidentiality obligations (which the Company shall use its reasonable efforts
to cause to be waived) each party shall afford the others and its accountants,
counsel and other representatives, reasonable access during normal business
hours during the period prior to the Effective Time to (a) all of its
properties, books, contracts, agreements and records, and (b) all other
information concerning the business, properties and personnel (subject to
restrictions imposed by applicable law) of it as the others may reasonably
request. No information or knowledge obtained in any investigation pursuant to
this Section 5.2 shall affect or be deemed to modify any representation or
warranty contained herein or the conditions to the obligations of the parties to
consummate the Merger.

        5.3 Confidentiality. Each of the parties hereto hereby agrees to and
reaffirms the terms and provisions of the Mutual Nondisclosure Agreement between
Parent and the Company dated as of December 9, 2000.

        5.4 Expenses. Whether or not the Merger is consummated, all fees and
expenses incurred in connection with the Merger including, without limitation,
all legal, accounting, financial advisory, consulting and all other fees and
expenses of third parties ("Third Party Expenses") incurred by a party in
connection with the negotiation and effectuation of the terms and conditions of
this Agreement and the transactions contemplated hereby, shall be the obligation
of the respective party incurring such fees and expenses (it being understood
that (a) Third Party Expenses of the Company will include, without limitation,
all fees and expenses payable to Pillsbury Madison & Sutro LLP in connection
with their representation of the Company with respect to the Merger, and (b) if
the Closing occurs, the reasonable Third Party Expenses referred to in paragraph
(a) of this sentence will be paid by Parent or the Surviving Corporation, and
not by the Stockholders).

        5.5 Public Disclosure. Upon execution and delivery of this Agreement by
the parties hereto, Parent and the Company shall release a jointly prepared
announcement describing the Merger. Except as aforesaid, unless otherwise
required by law (including, without limitation, securities laws) or, as to
Parent, by the rules and regulations of the National Association of Securities




                                      -34-
<PAGE>   36

Dealers, Inc., prior to the Effective Time, no disclosure (whether or not in
response to an inquiry) of the subject matter of this Agreement shall be made by
any party hereto unless approved by Parent and the Company prior to release,
provided that such approval shall not be unreasonably withheld.

        5.6 Consents. The Company shall use its reasonable efforts to obtain the
consents, waivers and approvals under any of the Contracts identified on
Schedule 2.12(c) as may be required in connection with the Merger.

        5.7 FIRPTA Compliance. On the Closing Date, the Company shall deliver to
Parent a properly executed statement in a form reasonably acceptable to Parent
for purposes of satisfying Parent's obligations under Treasury Regulation
Section 1.1445-2(c)(3).

        5.8 Reasonable Efforts. Subject to the terms and conditions provided in
this Agreement, each of the parties hereto shall use its reasonable efforts to
take promptly, or cause to be taken, all actions, and to do promptly, or cause
to be done, all things necessary, proper or advisable under applicable laws and
regulations to consummate and make effective the transactions contemplated
hereby to obtain all necessary waivers, consents and approvals and to effect all
necessary registrations and filings and to remove any injunctions or other
impediments or delays, legal or otherwise, in order to consummate and make
effective the transactions contemplated by this Agreement for the purpose of
securing to the parties hereto the benefits contemplated by this Agreement;
provided that Parent shall not be required to agree to any divestiture by Parent
or the Company or any of Parent's subsidiaries or affiliates of shares of
capital stock or of any business, assets or property of Parent or its
subsidiaries or affiliates or the Company or its affiliates material to Parent,
in Parent's reasonable judgement, or the imposition of any material limitation
on the ability of any of them to conduct their businesses or to own or exercise
control of such assets, properties and capital stock.

        5.9 Notification of Certain Matters. The Company shall give prompt
notice to Parent, and Parent shall give prompt notice to the Company, of (i) the
occurrence or non-occurrence of any event, the occurrence or non-occurrence of
which is likely to cause any representation or warranty of the Company and
Parent or Merger Sub, respectively, contained in this Agreement to be untrue or
inaccurate at or prior to the Effective Time except as contemplated by this
Agreement (including the Company Schedules) and (ii) any failure of the Company
or Parent, as the case may be, to comply with or satisfy in any material respect
any covenant, condition or agreement to be complied with or satisfied by it
hereunder; provided, however, that the delivery of any notice pursuant to this
Section 5.9 shall not limit or otherwise affect any remedies available to the
party receiving such notice.

        5.10 Additional Documents and Further Assurances. Each party hereto, at
the request of the other party hereto, shall execute and deliver such other
instruments and do and perform such other acts and things as may be reasonably
necessary or desirable for effecting completely the consummation of this
Agreement and the transactions contemplated hereby.

<PAGE>   37

        5.11 Form S-8. Parent shall file within 30 days after the Closing a

issuable with respect to assumed Company Options promptly after the Closing
Date, provided that the Company provides all necessary information for the
preparation of such registration statement.

        5.12 NMS Listing. Parent shall cause to be listed on the Nasdaq National
Market the shares of Parent Common Stock issuable, and those required to be
reserved for issuance, in connection with the Merger, upon official notice of
issuance.

        5.13 Cooperation With Financial Statements. The Company will use its
best efforts to cause the Company's management and its independent auditors to

financial statements as required by Parent to comply with applicable SEC
regulations, and (ii) the review of the Company's audit work papers, including
the examination of selected interim financial statements and data.

        5.14 Employee Benefits.

               (a) Parent shall take such reasonable actions as are necessary to
allow eligible employees of the Company to participate in the benefit programs
of Parent, or alternative benefits programs substantially comparable to those
applicable to employees of Parent on similar terms, as soon as practicable after
the Effective Time. Without limiting the generality of the foregoing, (i) to the
extent that any employee of the Company becomes eligible to participate in any
employee benefit plan of Parent after the Effective Time, Parent, the Surviving
Corporation and their subsidiaries shall credit such employee's service with the
Company, to the same extent as such service was credited under the similar
employee benefit plans of the Company immediately prior to the Effective Time,
for purposes of determining eligibility to participate in and vesting under, and
for purposes of calculating benefits under, such employee benefit plan of
Parent, and (ii) to the extent permitted by such employee benefit plan of Parent
and applicable law, Parent, the Surviving Corporation and its subsidiaries shall
waive any pre-existing condition limitations, waiting periods or similar
limitations under such employee benefit plan of Parent and shall provide each
such employee with credit for any co-payments previously made and any
deductibles previously satisfied.

               (b) Parent shall reserve the sum set forth on Schedule 5.14 in
cash, which sum shall be (i) allocated among those employees of the Company as
determined by the Company (and agreed to by Parent) prior to the Closing (the
"Participating Employees"), and (ii) paid to each such Participating Employee in
accordance with the terms set forth in Schedule 5.14.

        5.15 Parent shall cause the Surviving Corporation to pay severance costs
in accordance with its standard policies for employees of Parent to those
employees of the Company whose employment with the Surviving Corporation is
terminated.

        5.16 From and after the Effective Time, Parent will cause the Surviving
Corporation to fulfill and honor in all respects the obligations of the Company
pursuant to any indemnification agreements between the Company and its directors
and officers in effect immediately prior to the



                                      -36-
<PAGE>   38

Effective Time (the "INDEMNIFIED PARTIES") and any indemnification provisions
under the Company Certificate of Incorporation and Bylaws as in effect on the
date hereof. The Certificate of Incorporation and Bylaws of the Surviving
Corporation will contain provisions with respect to exculpation and
indemnification that are at least as favorable to the Indemnified Parties as
those contained in the Company Certificate of Incorporation and Bylaws as in
effect on the date hereof, which provisions will not be amended, repealed or
otherwise modified for a period of three (3) years from the Effective Time in
any manner that would adversely affect the rights thereunder of individuals who,
immediately prior to the Effective Time, were directors, officers, employees or
agents of the Company, unless such modification is required by law. Parent will
cause the Surviving Corporation to maintain Director and Officer insurance on
the same terms as the current policies with respect to the Indemnified Parties
for the three (3) years following the Effective Time.

        7.2 Obligation of the Company to Indemnify, Reimburse, etc. Subject to
the provisions of Section 7.4 hereof, the Company, its successors and assigns,
jointly and severally, shall indemnify, reimburse, defend, protect and hold
harmless Parent and Merger Sub and each of their successors and assigns and each
of their respective directors, officers, employees, affiliates, agents, and
their respective successors and assigns (each a "Parent Indemnitee") from and
against any claims, losses, liabilities, damages, causes of action, costs and
expenses (including reasonable attorney's, accountant's, consultant's and
expert's fees and expenses) (collectively "Losses") resulting from, imposed
upon, incurred or suffered by any of them, directly or indirectly, based upon,
arising out of or otherwise in respect of any inaccuracy in or any breach of any
representation, warranty (as modified by the Company Schedules), covenant or
agreement of the Company, contained in this Agreement.

        7.3 Obligation of Parent to Indemnify, Reimburse, etc. Subject to the
provisions of Section 7.4 hereof, Parent and Merger Sub and their respective
successors and assigns, jointly and severally, shall indemnify, reimburse,
defend, protect and hold harmless the Stockholders and their successors and
assigns and each of their directors, officers, employees, affiliates, agents,
and their respective successors and assigns (each a "Stockholder Indemnitee")
from and against any Losses resulting from, imposed upon, incurred or suffered
by any of them, directly or indirectly, based upon, arising out of or otherwise
in respect of any inaccuracy in or any breach of any representation or warranty,
but not any covenant or agreement of Parent, contained in this Agreement.

        7.4 Limits on Indemnification, Reimbursement, etc..

               (a) Absent fraud or willful misconduct of any party (for which
there shall be no limitation of liability of any party), no Parent Indemnitee
and no Stockholder Indemnittee shall have any right to seek or obtain
indemnification, reimbursement or defense under this Agreement or the Escrow
Agreement until Losses which would otherwise be indemnifiable hereunder, and
have been incurred by such party and other indemnitees associated with or
related to such party, exceed $1,000,000, after which such party or parties to
be indemnified hereunder shall be entitled to receive indemnification for all
Losses in excess of $1,000,000. In addition (absent fraud or willful
misconduct), neither Parent nor any Stockholder shall have any liability under
Article VII unless the Losses incurred by a Parent Indemnitee or a Stockholder
Indemnitee, as the case may be, in connection with a claim for indemnification
or reimbursement exceed $25,000, and the Losses related thereto shall be
disregarded for purposes of determining whether the $1,000,000 deductible set
forth in this Section 7.4(a) has been met.

               (b) Absent fraud or willful misconduct of the Company, from and
after the Closing, recourse of the Parent Indemnitees to the Loss Escrow Account
(as defined below) in the Escrow Fund shall be the sole and exclusive remedy of
the Parent Indemnitees for Losses relating directly or indirectly, based upon,
arising out of or otherwise in respect of any inaccuracy in or any breach of any
representation, warranty (as modified by the Company Schedules), covenant or
agreement of the Company, contained in this Agreement.

               (c) Absent fraud or willful misconduct, no party hereto shall be
entitled to recover punitive damages with respect to any breach of any
representation or warranty or non-performance of any obligation under this
Agreement (or otherwise relating to the transactions contemplated hereby), and
under no circumstances shall such damages be considered Losses under this
Article VII.

               (d) To the extent that any indemnifying party makes or is
required to make any indemnification or reimbursement payment to any indemnified
party, the indemnifying party shall be entitled to exercise, and shall be
subrogated to, any rights and remedies (including rights of indemnity, rights of
contribution and other rights of recovery) that the indemnified party may have
against any other person with respect to any Losses, circumstances or matters to
which such indemnification or reimbursement payment is directly or indirectly
related. Each indemnified party shall permit the indemnifying party to use the
name of the indemnified party in any transaction or in any proceeding or other
matter involving any of such rights or remedies; and the indemnified party shall
take such actions as the indemnifying party may reasonably request for the
purpose of enabling the indemnifying party to perfect or exercise the
indemnifying party's right of subrogation hereunder.

        7.5 Escrow Arrangements. Concurrent with the Effective Time, the Escrow
Amount shall be placed in an escrow fund (the "Escrow Fund"), to be governed by
the terms of the Escrow Agreement. Fifty percent (50%) of the Escrow Fund (the
"Loss Escrow Fund") shall be available to compensate Parent and its affiliates
for losses for which Parent or its affiliates are entitled to indemnification
under Article VII; the remainder of the Escrow Fund shall be released, if at
all, upon the happening of the events identified in Section 3 or Section 6(c) of
the Escrow Agreement. The terms and conditions of the Escrow Fund shall be set
forth more fully in the Escrow Agreement. Subject to the terms and conditions of
the Escrow Agreement, fifty percent (50%) of the Loss Escrow Fund shall be
distributed to the Stockholders in accordance with their pro rata interest in
the Escrow Fund on the sixth month anniversary of the Effective Time and the
balance of the Loss Escrow Fund, if any, shall be distributed to the
Stockholders on the one (1) year anniversary of the Effective Time.

                        TERMINATION, AMENDMENT AND WAIVER

        8.1 Termination. Except as provided in Section 8.2 below, this Agreement
may be terminated and the Merger abandoned at any time prior to the Effective
Time:

               (a) by mutual written consent of the Company and Parent;

               (b) by Parent or the Company if: (i) the Effective Time has not
occurred by March 31, 2000 (provided that the right to terminate this Agreement
under this clause 8.1(b)(i) shall not be available to any party whose willful
failure to fulfill any obligation hereunder has been the




                                      -41-
<PAGE>   43

cause of, or resulted in, the failure of the Effective Time to occur on or
before such date); provided, however, that if Parent shall file the Form S-4
Registration Statement in accordance with Section 5.1(iii), then the reference
to March 31, 2000 in this sentence shall be replaced with May 31, 2000; (ii)
there shall be a final nonappealable order of a federal or state court in effect
preventing consummation of the Merger; or (iii) there shall be any statute,
rule, regulation or order enacted, promulgated or issued or deemed applicable to
the Merger by any governmental entity that would make consummation of the Merger
illegal;

               (c) by Parent if there shall be any action taken, or any statute,
rule, regulation or order enacted, promulgated or issued or deemed applicable to
the Merger, by any Governmental Entity, which would: (i) prohibit Parent's or
the Company's ownership or operation of any portion of the business of the
Company or (ii) compel Parent or the Company to dispose of or hold separate, as
a result of the Merger, any portion of the business or assets of the Company or
Parent.

               (d) by Parent if it is not in material breach of its obligations
under this Agreement and there has been a breach of any representation,
warranty, covenant or agreement contained in this Agreement on the part of the
Company and as a result of such breach the conditions set forth in Section
6.3(a) or 6.3(b), as the case may be, would not then be satisfied; provided,
however, that if such breach is curable by the Company within thirty (30) days
through the exercise of its reasonable best efforts, then for so long as the
Company continues to exercise such reasonable best efforts Parent may not
terminate this Agreement under this Section 8.1(d) unless such breach is not
cured within thirty (30) days (but no cure period shall be required for a breach
which by its nature cannot be cured);

               (e) by the Company if it is not in material breach of its
obligations under this Agreement and there has been a breach of any
representation, warranty, covenant or agreement contained in this Agreement on
the part of Parent or Merger Sub and as a result of such breach the conditions
set forth in Section 6.2(a) or 6.2(b), as the case may be, would not then be
satisfied; provided, however, that if such breach is curable by Parent or Merger
Sub within thirty (30) days through the exercise of its reasonable best efforts,
then for so long as Parent or Merger Sub continues to exercise such reasonable
best efforts the Company may not terminate this Agreement under this Section
8.1(e) unless such breach is not cured within thirty (30) days (but no cure
period shall be required for a breach which by its nature cannot be cured).

        Where action is taken to terminate this Agreement pursuant to this
Section 8.1, it shall be sufficient for such action to be authorized by the
Board of Directors (as applicable) of the party taking such action.

        8.2 Effect of Termination. In the event of termination of this Agreement
as provided in Section 8.1, this Agreement shall forthwith become void and,
except as set forth in this Section 8.2, there shall be no liability or
obligation on the part of Parent, Merger Sub or the Company, or their respective
officers, directors or stockholders, provided that each party shall remain
liable for any willful breaches of this Agreement prior to its termination; and
provided further that, the provisions


                                      -42-
<PAGE>   44

of Sections 5.3 and 5.4 and Article IX of this Agreement shall remain in full
force and effect and survive any termination of this Agreement.

        8.3 Amendment. Except as is otherwise required by applicable law after
the stockholders of the Company approve this Agreement, this Agreement may be
amended by the parties hereto at any time by execution of an instrument in
writing signed on behalf of each of the parties hereto.

        8.4 Extension; Waiver. At any time prior to the Effective Time, Parent
and Merger Sub, on the one hand, and the Company, on the other, may, to the
extent legally allowed, (i) extend the time for the performance of any of the
obligations of the other party hereto, (ii) waive any inaccuracies in the
representations and warranties made to such party contained herein or in any
document delivered pursuant hereto, and (iii) waive compliance with any of the
agreements or conditions for the benefit of such party contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set forth in an instrument in writing signed on behalf of such
party.

        9.2 Interpretation. The words "include," "includes" and "including" when
used herein shall be deemed in each case to be followed by the words "without
limitation." The word "agreement" when used herein shall be deemed in each case
to mean any contract, commitment or other agreement, whether oral or written,
that is legally binding. As used in this Agreement, the phrase "to the best of
[a party's] knowledge," "to [a party's] knowledge," "[a party] is not aware,"
and similar phrases shall mean the actual knowledge of the officers and
directors of such party, after careful consideration of the matters set forth in
the representation that is so qualified and a reasonably diligent review of all
files, documents, agreements and other materials in such person's possession or
subject to his or her control. The table of contents and headings contained in
this Agreement are for reference purposes only and shall not affect in any way
the meaning or interpretation of this Agreement.

        9.3 Counterparts. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other party, it being understood that all
parties need not sign the same counterpart.

        9.4 Entire Agreement; Assignment. This Agreement, the schedules and
Exhibits hereto, and the documents and instruments and other agreements among
the parties hereto referenced herein: (a) constitute the entire agreement among
the parties with respect to the subject matter hereof and supersede all prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter hereof; (b) are not intended to confer upon any
other person (other than the Stockholder Indemnittees and those persons referred
to in Sections 5.14 and 5.15) any rights or remedies hereunder; and (c) shall
not be assigned by operation of law or otherwise except as otherwise
specifically provided, except that Parent and Merger Sub may assign their



                                      -44-
<PAGE>   46

respective rights and delegate their respective obligations hereunder to their
respective affiliates as long as such assignment or delegation does not
adversely affect the rights of the Company stockholders.

        9.5 Severability. In the event that any provision of this Agreement or
the application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties hereto. The parties further agree to replace
such void or unenforceable provision of this Agreement with a valid and
enforceable provision that will achieve, to the extent possible, the economic,
business and other purposes of such void or unenforceable provision.

        9.6 No Implied Representations. Parent and the Company acknowledge that,
except as expressly provided in Articles II and II, and except as expressly
provided in any document delivered by a party hereto to any other party hereto
in connection with the transactions contemplated hereby, none of the parties
(and no other person) has made or is making any representations or warranties
whatsoever, implied or otherwise.

        9.7 Other Remedies. Except as otherwise provided herein (including in
Section 7.4), any and all remedies herein expressly conferred upon a party will
be deemed cumulative with and not exclusive of any other remedy conferred
hereby, or by law or equity upon such party, and the exercise by a party of any
one remedy will not preclude the exercise of any other remedy.

        9.8 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of California, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.
Each of the parties hereto agrees that process may be served upon them in any
manner authorized by the laws of the State of California for such persons and
waives and covenants not to assert or plead any objection which they might
otherwise have to such jurisdiction and such process.

        9.9 Rules of Construction. The parties hereto agree that they have been
represented by counsel during the negotiation and execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule of
construction providing that ambiguities in an agreement or other document will
be construed against the party drafting such agreement or document.

        9.10 Specific Performance. The parties hereto agree that irreparable
damage would occur in the event that any of the provisions of this Agreement
were not performed in accordance with their specific terms or were otherwise
breached. It is accordingly agreed that the parties shall be entitled to an
injunction or injunctions to prevent breaches of this Agreement and to enforce
specifically the terms and provisions hereof in any court of the United States
or any state having jurisdiction, this being in addition to any other remedy to
which they are entitled at law or in equity.

California corporation ("Parent"), Compass Holding Corp., a Delaware corporation
and a wholly owned subsidiary of Parent ("Parent Sub"), Compass Acquisition
Corp., a Delaware corporation and a wholly-owned subsidiary of Parent Sub
("Holding"), 3034996 Nova Scotia Company, a Nova Scotia unlimited liability
company and a wholly owned subsidiary of Holding ("Holding ULC") and 3034997
Nova Scotia Company, a Nova Scotia unlimited liability company and a wholly
owned subsidiary of Holding ULC ("Amalgamation Sub") (collectively Parent,
Parent Sub, Holding, Holding ULC and Amalgamation Sub are referred to as the

"Company").

                                    RECITALS

        A. The Boards of Directors of each of the Company and the Parent
Companies believe it is in the best interests of each company and their
respective stockholders that the Parent acquire the Company (the "Acquisition"),
subject to the terms and conditions of this Agreement, and in furtherance
thereof, have approved the Acquisition.

        B. Pursuant to the Acquisition, among other things, and subject to the
terms and conditions of this Agreement, the following will occur:

            (i) the Company will be continued from the corporate laws of the
Province of Ontario to the corporate laws of the Province of Nova Scotia (the
"Continuance");

            (ii) Holding ULC will acquire all of the issued and outstanding
common shares of the Company (the "Company Capital Stock") held by the Company's
shareholders who are resident in the United States and shareholders who are
United States persons, identified as such on Schedule 2.2(a)(ii) (the "US
Sellers"), in exchange for cash and shares of Parent common stock ("Parent
Common Stock");

            (iii) each of the Company's shareholders who are not United States
residents or persons may elect to contribute all of that shareholder's Company
Capital Stock to a holding company (each, a "Holding Company") to be newly
established to hold those shares (and the securities into which they are
subsequently exchanged as contemplated herein);

            (iv) the Company will form a wholly-owned Nova Scotia unlimited
liability company and amalgamate (the "First Amalgamation") with that company to
form an unlimited liability company ("East ULC");

            (v) the Company (or its successor East ULC) will amalgamate with

Amalgamation ("Exchangeco"); and

            (vi) a reorganization will be effected (the "Reorganization")
pursuant to which (i) the memorandum and articles of association of Exchangeco

agreement will be entered into among Parent, Exchangeco and a Canadian trust
company (the "Voting and Exchange Trust Agreement") in substantially the form

entitled to vote as though the holder held the Parent Common Stock issuable upon
exchange of that holder's Exchangeable Shares.

        D. Concurrently with the execution of this Agreement, and as a condition
and inducement to the Parent Companies' willingness to enter into this
Agreement, certain affiliates of the Company will enter into a shareholder
implementation agreement in the form attached hereto as Exhibit 1 (the
"Shareholder Implementation Agreement").

        E. A portion of the Parent Common Stock and Exchangeable Shares
otherwise receivable by the Company's shareholders in connection with the
Acquisition will be placed in escrow pursuant to an escrow agreement (the
"Escrow Agreement"), in substantially the form attached as Exhibit 8, the
release of which will be contingent upon certain events and conditions.

        F. Concurrently with the execution of this Agreement, Parent will enter
into a shareholder reimbursement agreement in the form attached as Exhibit 2
(the "Shareholder Reimbursement Agreement") establishing a fund of $5 million
cash to be used to pay for expenses and tax consequences, if any, of
shareholders of the Company in connection with the establishment of the Holding
Companies.

        NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable consideration,
intending to be legally bound hereby the parties agree as follows:

<PAGE>   9

recapitalization or other like change with respect to capital stock of
Exchangeco or Company Capital Stock occurring after the date hereof and prior to
the Final Closing.

        1.5 Reorganization of Capital of Exchangeco. Immediately after the
Second Amalgamation, Exchangeco shall effect a capital reorganization whereby
each outstanding Class B Share held by the Parent Companies shall be transferred
to Exchangeco in exchange for Exchangeco Common Shares and all other Class B
Shares shall be transferred by the holder thereof to Exchangeco in exchange for
that amount of cash and that number of fully paid and non-assessable
Exchangeable Shares as determined in accordance with Section 1.6. The terms and
provisions of the Exchangeable Shares, including the basis on which the
shareholders shall have the right to exchange Exchangeable Shares of Exchangeco
for shares of Parent Common Stock, shall be as set forth in the provisions
attaching to the Exchangeable Shares set forth in the form attached as Exhibit 5
and the voting and exchange trust agreement set forth in the form attached as
Exhibit 6 (the "Voting and Exchange Trust Agreement").

        1.6 Allocation of Consideration. The aggregate purchase price to be paid
by Parent in connection with the Acquisition will be $30,000,000 cash (subject
to reduction as described below) and 4,092,280 shares of Parent Common Stock.
Within fifteen days of the date of this Agreement, the Company shall deliver to
Parent and Holding ULC a schedule (the "Initial Closing Schedule") which shall
set forth:

                (A)(i) a listing of all of the US Sellers together with the
number of shares of Company Capital Stock held by each, and (ii) the aggregate
amount of cash to be paid by Holding ULC to each US Seller in consideration for
the acquisition of their shares of Company Capital Stock at the Initial Closing
(as to each US Seller, the "Initial Closing Cash Payment"), and (iii) the
aggregate number of shares of Parent Common Stock to be issued to each US Seller
in consideration for their shares of Company Capital Stock at the Initial
Closing (as to each US Seller, the "Initial Closing Parent Shares"). In no event
shall the aggregate of all Initial Closing Cash Payments to be paid to the US
Sellers exceed $30,000,000 less the amount outstanding as of the Initial Closing
Date under the Convertible Promissory Note (the "Convertible Promissory Note")
dated August 3, 1999 (the "Aggregate Cash Purchase Price") and in no event shall
the aggregate of all Initial Closing Parent Shares to be issued to the US
Sellers exceed 4,092,280 shares of Parent Common Stock (the "Aggregate Share
Number"). The aggregate amount of purchase price consideration payable to all US
Sellers identified on the Initial Closing Schedule, either in the form of cash
or shares of Parent Common Stock (valued for this purpose at $39.098 per share)
or a combination of the two, allocated to each share of Company Capital Stock to
be acquired by Holding ULC at the Initial Closing will be equal; however, the
form of consideration (cash or shares) to be allocated to each shareholder may
be different;

                (B)(i) a listing of all of the non-US Sellers together with the
number of shares of Company Capital Stock held by each, and (ii) the aggregate
amount of cash to be issued by Exchangeco to each non-US Seller upon exchange of
their Class B Shares in the Reorganization (as to each non-US Seller, the
"Reorganization Cash Payment"), and (iii) the aggregate number of Exchangeable
Shares to be issued to each non-US Seller upon exchange of

                                      -6-
<PAGE>   10

their Class B Shares in the Reorganization (as to each non-US Seller, the
"Reorganization Exchangeable Shares"). In no event shall the aggregate of all
Reorganization Cash Payments to be paid to the non-US Sellers exceed the
Aggregate Cash Purchase Price less the aggregate amount of cash paid as Initial
Closing Cash Payments and in no event shall the aggregate of all Reorganization
Exchangeable Shares to be issued to the non-US Sellers exceed the Aggregate
Share Number less the aggregate number of Initial Closing Parent Shares issued
to US Sellers in connection with the Initial Closing. The aggregate amount of
purchase price consideration, either in the form of cash or Exchangeable Shares
(the Parent Common Stock into which the Exchangeable Shares may be converted is
valued for this purpose at $39.098 per share) or a combination of the two,
allocated to each share of Company Capital Stock to be converted to Class B
Shares and subsequently to Exchangeable Shares shall be equal; however, the form
of consideration (cash or shares) to be allocated to each share may be
different.

        Parent acknowledges that the Company has informed Parent of Company's
intention to set forth on the Initial Closing Schedule an allocation among its
shareholders of the Aggregate Cash Purchase Price to reflect first the payment
of any required purchase price withholding tax, second the payment of the tax
liabilities of the US Sellers associated with the Acquisition and third the
payment of the tax liabilities of the non-US Sellers associated with the
Acquisition, with any remaining cash consideration being allocated among all of
the Company's shareholders based upon their respective equity interests in the
Company. Notwithstanding the foregoing, the relevant Parent Companies shall be
obligated to distribute the Aggregate Cash Purchase Price that is payable under
this Section 1.6 only according to the allocation set forth on the Initial
Closing Schedule.

        1.7 Purchase of Company Capital Stock from U.S. Sellers. Upon the
Initial Closing (as defined in Section 7.1), Holding ULC will acquire each
issued and outstanding share of Company Capital Stock held by US Sellers in
exchange for the cash and number of shares of Initial Closing Parent Shares per
share of Company Capital Stock payable to the U.S. Sellers in the amounts set
forth on the Initial Closing Schedule; however, all such cash and Parent Common
Stock will be held in escrow in accordance with the provisions set forth in
Section 7.2 and the acquisition of all Company Capital Stock by Holding ULC from
the US Sellers will be unwound if the Second Amalgamation is not completed; and
provided further, however that such amounts identified on Initial Closing
Schedule shall be adjusted to reflect fully the effect of any stock split,
reverse split, stock dividend (including any dividend or distribution of
securities convertible into capital stock of Exchangeco or Company Capital
Stock), reorganization, recapitalization or other like change with respect to
capital stock of Exchangeco or Company Capital Stock occurring after the date
hereof and prior to the Initial Closing. If at the time of the unwinding the
First Amalgamation shall have occurred, the Company and the shareholders of the
Company (or its successor East ULC) shall take such actions as are necessary to
cause East ULC to file a valid and timely election to be treated as an
association taxable as a corporation for United States federal income tax
purposes.

                                      -7-
<PAGE>   11

        1.8 Escrow Amount. In addition to the foregoing, Exchangeco shall be
entitled to withhold a percentage of the Exchangeable Shares issuable to non-US
Sellers (other than Exchangeable Shares that may be issuable to any Parent
Companies) and a percentage of the Parent Common Stock issuable to the US
Sellers (collectively the "Escrow Amount") such that the total percentage of the
shares so withheld equal 11.875 percent of the aggregate number of Parent Common
Stock issuable (i) to the US Sellers and (ii) issuable to non-US Sellers holding
Exchangeable Shares on the exchange of the Exchangeable Shares, on the terms and
conditions contained in the Escrow Agreement. The Escrow Amount will be withheld
on a pro rata basis among all the shareholders of the Company based upon their
respective equity interests in the Company.

        1.9 Taking of Necessary Action; Further Action. If, at any time after
the Final Closing, any such further action is necessary or desirable to carry
out the purposes of this Agreement and to vest Exchangeco with full right, title
and possession to all assets, property, rights, privileges, powers and
franchises of the Company (or its successor East ULC) and Amalgamation Sub, the
resolutions passed by the Company and Amalgamation Sub will provide that the
officers and directors of the Company and Amalgamation Sub are fully authorized
in the name of their respective corporations or otherwise to take, and will
take, all such lawful and necessary action.

to be done, all things necessary, proper or advisable under applicable laws and
regulations to consummate and make effective the transactions contemplated
hereby to obtain all necessary waivers, consents and approvals and to effect all
necessary registrations and filings and to remove any injunctions or other
impediments or delays, legal or otherwise, in order to consummate and make
effective the transactions contemplated by this Agreement for the purpose of
securing to the parties hereto the benefits contemplated by this Agreement;
provided that Parent shall not be required to agree to any divestiture by Parent
or the Company or any of Parent's subsidiaries or affiliates of shares of
capital stock or of any business, assets or property of Parent or its
subsidiaries or affiliates or the Company or its affiliates, or the imposition
of any material limitation on the ability of any of them to conduct their
businesses or to own or exercise control of such assets, properties and capital
stock; and further provided that the Company shall not be obligated to complete
the Initial Closing before January 4, 2000.

        5.7 Notification of Certain Matters. The Company shall give prompt
notice to Parent, and Parent shall give prompt notice to the Company, of (i) the
occurrence or non-occurrence of any event, the occurrence or non-occurrence of
which is likely to cause any representation or warranty of the Company and
Parent or Amalgamation Sub, respectively, contained in this Agreement to be
untrue or inaccurate at or prior to the Initial Closing except as contemplated
by this Agreement (including the Company Schedules) and (ii) any failure of the
Company or Parent, as the case may be, to comply with or satisfy in any material
respect any covenant, condition or agreement to be complied with or satisfied by
it hereunder; provided, however, that the delivery of any notice pursuant to
this Section 5.7 shall not limit or otherwise affect any remedies available to
the party receiving such notice.

        5.8 NMS Listing. Parent shall cause to be listed on the Nasdaq National
Market the shares of Parent Common Stock issuable, and those required to be
reserved for issuance, in connection with the transactions contemplated hereby
and upon the exchange of the Exchangeable Shares, upon official notice of

efforts to cause the Company's management and its independent auditors to
facilitate on a timely basis (i) the

                                      -29-
<PAGE>   33

preparation of historical and pro forma financial statements as required by
Parent to comply with applicable SEC regulations, and (ii) the review of the
Company's 1997 and 1998 audit work papers, including the examination of selected
interim financial statements and data.

        5.10 Employee Benefits.

            (a) Parent shall take such reasonable actions as are necessary to
allow eligible employees of the Company to participate in the benefit programs
of Parent, or alternative benefits programs substantially comparable to those
applicable to employees of Parent on similar terms, as soon as practicable after
the Final Closing. Employees of the Company who are employed by Parent or the
Company following the Final Closing shall be granted credit for service with the
Company prior to the Final Closing for all purposes as if such service with the
Company was service with Parent or a subsidiary of Parent.

            (b) Parent shall reserve an aggregate of $5,000,000 in cash, which
will be distributed to those employees of the Company to be identified by mutual
agreement of the Parent and the Company in the amounts mutually agreed upon by
Parent and the Company prior to the Initial Closing and distributed in
accordance with the terms of such agreement.

        5.11 Registration Rights. Upon the issuance and release from the Interim
Escrow of Parent Common Stock to US Sellers at the Final Closing and upon the
issuance of Parent Common Stock to holders (collectively, including the US
Sellers, the "Holders") of Exchangeable Shares pursuant to the terms of the
Exchangeable Share Provisions, the Holders shall have registration rights with
respect to such shares of Parent Common Stock (the "Registrable Securities")
subject to the following terms and conditions:

            (a) Registration on Form S-3. Within five (5) business days after
Parent becomes a registrant entitled to use a Form S-3 registration statement or
any successor form thereto to register the resale (which shall not be through an
underwritten public offering) of the Registrable Securities (the "S-3 Date"),
Parent shall use reasonable best efforts to cause the Registrable Securities to
be registered so as to permit the resale thereof, and in connection therewith
shall prepare and file a Form S-3 registration statement or any successor form
thereto providing for an offering to be made on a continuous basis pursuant to
Rule 415 under the Securities Act (the "Registration Statement") with the SEC
under the Securities Act of 1933, as amended (the "Securities Act") to effect
such registration within five (5) business days after the S-3 Date, and
thereafter Parent shall use its reasonable best efforts to cause the
Registration Statement to be declared effective under the Securities Act as soon
as practicable after the filing thereof; provided, however, that if Parent shall
furnish to the Chief Executive Officer of the Company and to Toucan, to the
attention of the name and at the address provided by Toucan in writing to the
Parent, a certificate signed by the Chief Executive Officer of Parent stating
that, in the good faith judgment of the Board of Directors or Chief Executive
Officer of Parent, it would be seriously detrimental to Parent and its
shareholders for the Registration Statement to be filed on or before the date
filing would otherwise be required, and it is therefore in the best interests of
Parent to defer the filing of the Registration Statement, then Parent may delay
the filing of the Registration Statement, once but not more than once, for a
period not in excess of forty-five (45) days.

                                      -30-
<PAGE>   34

            (b) Expenses of Registration. Parent shall pay all Registration
Expenses (as hereafter defined) in connection with any registration,
qualification or compliance pursuant to this Section 5.13, and each Holder shall
pay all Selling Expenses (as hereafter defined) and other expenses that are not
Registration Expenses relating to the Registrable Securities resold by such
Holder. For purposes of this Section 5.13(b), "Registration Expenses" shall mean
all expenses, except as otherwise stated below, incurred by Parent in complying
with Sections 5.13(a) and 5.13(c), including, without limitation, all
registration, qualification and filing fees, printing expenses, escrow fees,
fees and disbursements of counsel for Parent, blue sky fees and expenses and the
expense of any special audits incident to or required by any such registration.
For purposes of this Section 5.13(b), "Selling Expenses" shall mean all selling
discounts commissions and stock transfer or other Governmental Charges
applicable to the Registrable Securities and all fees and disbursements of
counsel for any Holder.

            (c) Registration Procedures. In the case of any registration
effected by Parent pursuant to this Section 5.13, Parent will keep each Holder
advised in writing as to the initiation of each registration and as to the
completion thereof. Parent will:

                (i) Use reasonable best efforts to keep such registration
effective until the earlier of (A) all Holders having completed the distribution
described in the registration statement relating thereto or (B) the sixth
anniversary of the date of the Final Closing;

                (ii) Promptly prepare and file with the SEC such amendments and
supplements to the Registration Statement and the prospectus used in connection
with the Registration Statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by the Registration Statement;

                (iii) Furnish such number of prospectuses and other documents
incident thereto, including any amendment of or supplement to the prospectus, as
a Holder from time to time may reasonably request;

                (iv) Subject to Section 5.13(h)(ii) hereof, notify each Holder
of Registrable Securities covered by the Registration Statement at any time when
a prospectus relating thereto is required to be delivered under the Securities
Act of the happening of any event as a result of which the prospectus included
in the Registration Statement, as then in effect, includes an untrue statement
of a material fact or omits to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in the light
of the circumstances then existing, and at the request of any such Holder,
prepare and furnish to such Holder a reasonable number of copies of a supplement
to or an amendment of such prospectus as may be necessary so that, as thereafter
delivered to the purchasers of such shares, such prospectus shall not include an
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein not misleading in
the light of the circumstances then existing;

                (v) Cause all such Registrable Securities registered pursuant to
the Registration Statement to be listed on each securities exchange or quotation
system on which similar securities issued by Parent are then listed or quoted,
and in connection therewith, file with the

                                      -31-
<PAGE>   35

Nasdaq National Market an application for listing of additional shares with
respect to the Registrable Securities;

                (vi) Provide a transfer agent and registrar for all Registrable
Securities registered pursuant to the Registration Statement and a CUSIP number
for all such Registrable Securities, in each case not later than the effective
date of the Registration Statement;

                (vii) Use its reasonable best efforts to register or qualify the
Registrable Securities covered by the Registration Statement under such other
securities or blue sky laws of such jurisdiction within the United States and
Puerto Rico as shall be reasonably appropriate for the distribution of the
Registrable Securities covered by the Registration Statement; provided, however,
that Parent shall not be required in connection therewith or as a condition
thereto to qualify to do business in or file a general consent to service of
process in any jurisdiction wherein it would not but for the requirements of
this paragraph be obligated to do so; and

                (viii) Otherwise use its reasonable best efforts to comply with
all applicable rules and regulations of the SEC, and make available to its
security holders, as soon as reasonably practicable, an earnings statement
covering a period of at least twelve months, but not more than eighteen months,
beginning with the first month after the effective date of the Registration
Statement, which earnings statement shall satisfy the provisions of Section
11(a) of the Securities Act.

            (d) Information by Holder. Each Holder of Registrable Securities
shall furnish to Parent such information regarding such Holder and the
distribution proposed by such Holder as Parent may reasonably request in
connection with any registration, qualification or compliance referred to in
this Section 5.13, but only to the extent that such information is required in
order for Parent to comply with its obligations under all applicable securities
and other laws and to ensure that the Registration Statement relating to such
Registrable Securities conforms to the applicable requirements of the Securities
Act and the rules and regulations thereunder. Each Holder covenants that it will
promptly notify Parent of any changes in the information set forth in the
Registration Statement or otherwise provided by such Holder to Parent regarding
such Holder or such Holder's plan of distribution as a result of which the
Registration Statement or any prospectus relating to the Registrable Securities
contains or would contain an untrue statement of a material fact regarding such
Holder or its intended method of distribution of such Registrable Securities or
omits to state any material fact regarding such Holder or its intended method of
distribution of such Registrable Securities required to be stated therein or
necessary to make the statements therein, not misleading.

            (e) Indemnification and Contribution.

                (i) Parent agrees to indemnify and hold harmless each Holder
from and against any losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) to which such Holder may become subject (under
the Securities Act or otherwise) insofar as such losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) arise out of, or are
based upon, any untrue statement, alleged untrue statement, omission or alleged
omission of a material fact in the Registration Statement, any prospectus
included in the Registration Statement, or

                                      -32-
<PAGE>   36

any amendment or supplement to the Registration Statement or any such
prospectus, and Parent will, as incurred, reimburse such Holder for any legal or
other expenses reasonably incurred in investigating, defending or preparing to
defend any such action, proceeding or claim; provided, however, that Parent
shall not be liable in any such case to the extent that such loss, claim, damage
or liability arises out of, or is based upon (A) an untrue statement or alleged
untrue statement made in such Registration Statement in reliance upon and in
conformity with written information furnished to Parent by such Holder in an
instrument executed by such Holder and specifically stated to be for use in the
preparation of the Registration Statement, (B) the failure of such Holder to
comply with any of the covenants and agreements contained in Sections 5.13(f) or
5.13(h) hereof, or (C) any untrue statement in any prospectus that is corrected
in any subsequent prospectus that was delivered to the Holder prior to the
pertinent sale or sales by the Holder.

                (ii) Each Holder, severally and not jointly, agrees to indemnify
and hold harmless Parent from and against any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) to which Parent may
become subject (under the Securities Act or otherwise) insofar as such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof)
arise out of, or are based upon (A) an untrue statement, alleged untrue
statement, omission or alleged omission of a material fact in the Registration
Statement, any prospectus included in the Registration Statement, or any
amendment or supplement to the Registration Statement or any such prospectus in
reliance upon and in conformity with written information furnished to Parent by
such Holder in an instrument executed by such Holder and specifically stated to
be for use in preparation of the Registration Statement, provided, however, that
no Holder shall be liable in any such case for any untrue statement included in
any Prospectus which statement has been corrected in a writing delivered to
Parent at least two business days before the sale from which such loss arose,
(B) the failure of such Holder to comply with any of the covenants and
agreements contained in Sections 5.13(f) or 5.13(h) hereof, or (C) any untrue
statement in any Prospectus that is corrected in any subsequent Prospectus that
was delivered to the Holder prior to the pertinent sale or sales by the Holder;
and each Holder, severally and not jointly, will, as incurred, reimburse Parent
for any legal or other expenses reasonably incurred in investigating, defending
or preparing to defend any such action, proceeding or claim. In no event shall
the amount payable by any Holder to Parent pursuant to this Section 5.13(e)(ii)
by reason of a sale of Parent Common Stock by such Holder exceed the amount of
the gross proceeds to such Holder from the sale of Parent Common Stock from
which such liability arose.

                (iii) Promptly after receipt by any indemnified person under
subsections (i) or (ii) above of a notice of a claim or the beginning of any
action in respect of which indemnity is to be sought against an indemnifying
person pursuant to this Section 5.13(e), such indemnified person shall notify
the indemnifying person in writing of such claim or of the commencement of such
action (provided, however, that no failure to provide such notice shall relieve
any indemnifying person of any liability hereunder except to the extent that
such indemnifying person is prejudiced thereby), and, subject to the provisions
hereinafter stated, in case any such action shall be brought against an
indemnified person and the indemnifying person shall have been notified thereof,
the indemnifying person shall be entitled to participate therein, and, to the
extent that it shall wish, to assume the defense thereof, with counsel
reasonably satisfactory to the indemnified person. After

                                      -33-
<PAGE>   37

notice from the indemnifying person to such indemnified person of the
indemnifying person's election to assume the defense thereof, the indemnifying
person shall not be liable to such indemnified person for any legal expenses
subsequently incurred by such indemnified person in connection with the defense
thereof; provided, however, that, if the indemnifying person shall propose that
the same counsel represent it and the indemnified person, and if counsel for the
indemnified person shall reasonably have concluded that there is an actual
conflict of interest posed by the representation proposed by the indemnifying
person, the indemnified person shall be entitled to retain its own counsel
reasonably satisfactory to the indemnifying person at the expense of such
indemnifying person; provided, however that if more than one indemnified person
makes a claim against an indemnifying person based on substantially similar
facts, the indemnifying person shall not be responsible for the fees of more
than one counsel for all indemnified persons whose claims are based on
substantially similar facts.

                (iv) If the indemnification provided for in this Section 5.13(e)
is unavailable to or insufficient to hold harmless an indemnified party under
subsection (i) or (ii) above in respect of any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) referred to therein,
then each indemnifying party shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (or actions in respect thereof), in such proportion as is
appropriate to reflect the relative fault of each such party, as well as any
other relevant equitable considerations. The relative fault shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by Parent on the one hand or a
Holder on the other and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
Parent and the Holders agree that it would not be just and equitable if
contribution pursuant to this Section 5.13(e)(iv) were determined by any method
of allocation which does not take account of the equitable considerations
referred to above in this Section 5.13(e)(iv). The amount paid or payable by an
indemnified party as a result of the losses, claims, damages, or liabilities (or
actions in respect thereof) referred to above in this Section 5.13(e)(iv) shall
be deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action,
proceeding or claim. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

                (v) The obligations of the Parent and the Holders under this
Section 5.13(e) shall be in addition to any liability which Parent and the
respective Holders may otherwise have and shall extend, upon the same terms and
conditions, to each director and officer of Parent or any Holder, and to each
person, if any, who controls Parent or any Holder within the meaning of the
Securities Act or the Exchange Act.

            (f) Restrictions on Transferability. The shares of Parent Common
Stock issuable pursuant to the terms of the Exchangeable Share Provisions in a
transaction exempt from the registration requirements of the Securities Act (the
"Restricted Shares") shall not be transferable except (A) in accordance with the
Registration Statement, in which case Holder must comply with

                                      -34-
<PAGE>   38

the requirement of delivering a current prospectus, (B) in accordance with Rule
144, or (C) pursuant to an exemption from the registration requirements of the
Securities Act. Parent shall be entitled to give stop transfer instructions to
its transfer agent with respect to the Restricted Shares in order to enforce the
foregoing restrictions.

            (g) Restrictive Legend. Each certificate representing Restricted
Shares shall bear substantially the following legends (in addition to any
legends required under applicable securities laws):

        THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
INVESTMENT PURPOSES ONLY AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933. THE SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH
REGISTRATION OR AN EXEMPTION THEREFROM.

ADDITIONALLY, THE TRANSFER OF THE SHARES REPRESENTED BY THIS CERTIFICATE IS
SUBJECT TO CERTAIN RESTRICTIONS SPECIFIED IN THE MERGER AGREEMENT AND PLAN OF
REORGANIZATION AMONG THE ISSUER, COMPASS ACQUISITION CORP., COMPASS HOLDING
CORP. 3034996 NOVA SCOTIA COMPANY, 3034997 NOVA SCOTIA COMPANY AND THE DOCSPACE
COMPANY INC. DATED NOVEMBER 3, 1999 (THE "AGREEMENT"), AND NO TRANSFER OF SHARES
SHALL BE VALID OR EFFECTIVE ABSENT COMPLIANCE WITH SUCH RESTRICTIONS. COPIES OF
THE AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE
REGISTERED HOLDER OF THIS CERTIFICATE TO THE SECRETARY OF THE COMPANY.

        The legend contained in this Section 5.13(g) shall be removed from a
certificate in connection with any sale in compliance with the terms of this
Agreement and pursuant to the Registration Statement, but shall not be removed
in any other circumstance without Parent's prior written consent (which consent
shall not be unreasonably withheld or delayed and shall be granted if such
legend is no longer appropriate).

            (h) Transfer of Shares After Registration.

                (i) Restriction. Restricted Shares are not transferable on the
books of Parent unless the certificate submitted to Parent's transfer agent
evidencing such Restricted Shares is accompanied by a separate certificate, in
form and substance reasonably satisfactory to Parent, executed by an officer of,
or other person duly authorized by, the Holder for purposes of establishing
compliance with this Agreement.

                (ii) Notice to Parent of Proposed Sale and Right of Parent to
Suspend Use of Registration Statement. If any Holder shall propose to sell any
Registrable Securities pursuant to the Registration Statement, it shall notify
Parent of its intent to do so at least three (3) full business days prior to
such sale. Such notice shall be deemed to constitute a representation that any
information previously supplied by such Holder (including without limitation the
information referred to in Section 5.13(d) hereof) is accurate as of the date of
such notice. At any time within

                                      -35-
<PAGE>   39

such three (3) business-day period, Parent may refuse to permit the Holder to
resell any Registrable Securities pursuant to the Registration Statement (the
"Suspension Right"); provided, however, that in order to exercise its Suspension
Right, Parent must deliver a certificate (the "Suspension Notice") in writing to
the Holder to the effect that, in the good faith judgement of the Board of
Directors or Chief Executive Officer of Parent, a delay in such sale is
necessary because a sale pursuant to such Registration Statement in its
then-current form would be seriously detrimental to Parent and its shareholders
and therefore it is in the best interests of Parent to delay the sale under the
Registration Statement. In no event shall such delay exceed forty-five (45)
calendar days (a "Suspension Period"), and provided further, however, that in no
event shall Parent be permitted to exercise its Suspension Right more than three
times in any single calendar year. The date on which a Suspension Notice is
delivered by the Company to the first Holder desiring to sell Registrable
Securities who is so notified in any Suspension Period shall be considered the
start of such Suspension Period and shall constitute one exercise of a
Suspension Right under this subsection, provided, however, any subsequent
Suspension Notice delivered during a Suspension Period shall not be considered a
separate exercise of Parent's Suspension Right. Each Suspension Notice shall set
forth (a) the date on which the Suspension Period covered by such Suspension
Notice commenced and (b) the number of times Parent has exercised its Suspension
Right previously during the same calendar year. Parent agrees that any
Suspension Right imposed on the Holders will be imposed consistently among all
Holders requesting to sell any Registrable Securities during any Suspension
Period.

            (i) Rule 144 Reporting. With a view to making available the benefits
of certain rules and regulations of the SEC which may at any time permit the
sale of the Registrable Securities to the public without registration, or
pursuant to a registration on Form S-3, Parent agrees to use its reasonable best
efforts to:

                (i) Make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act, at all times
after the Amalgamation;

                (ii) File with the SEC in a timely manner all reports and other
documents required of Parent under the Securities Act and the Exchange Act; and

                (iii) So long as a Holder owns any Registrable Securities, to
furnish to that Holder forthwith upon request a written statement by Parent as
to its compliance with the reporting requirements of said Rule 144, and of the
Securities Act and the Exchange Act, a copy of the most recent annual or
quarterly report of Parent, and such other reports and documents of Parent as
such Holder may reasonably request in availing itself of any rule or regulation
of the SEC allowing such Holder to sell any such Registrable Securities without
registration.

            (j) Transfer of Registration Rights. The rights and obligations of
any Holder under this Section 5.13 may be assigned to a transferee or assignee
in connection with any transfer or assignment of Registrable Securities by a
Holder; provided that: (i) such transfer may otherwise be effected in accordance
with applicable securities laws, (ii) Parent is, within a reasonable time after
such transfer, furnished with written notice of the name and address of such
transferee or assignee and the securities with respect to which such
registration rights are being assigned under, (iii) each

                                      -36-
<PAGE>   40

transferee shall agree to be bound by all of the provisions of this Section
5.13; and (iv) such assignment shall be effective only if immediately following
such transfer the further disposition of such Registrable Securities by the
transferee or assignee is restricted under the Securities Act.

        5.12 Securities Compliance. The Parent Companies and the Company shall
use all reasonable efforts to obtain all orders required from the applicable
Canadian securities authorities to permit (a) the issuance of the Exchangeable
Shares in exchange for Company Capital Stock; (b) the issuance of Parent Common
Stock upon exchange of the Exchangeable Shares in accordance with their terms or
the Voting and Exchange Trust Agreement; and (c) the sale of the Parent Common
Stock outside of Canada, in each case without qualification with or approval of
or the filing of any document, including any prospectus or similar document, or
the taking of any proceeding with, or the obtaining of any further order, ruling
or consent from, any governmental entity or regulatory authority under the
Canadian federal and provincial securities or other laws applicable to residents
of Ontario, British Columbia, Alberta and Nova Scotia or pursuant to the rules
and regulations of any regulatory authority administering such laws, or the
fulfillment of any other legal requirement in any such jurisdiction (other than,
with respect to such first resales, any restrictions on transfer by reason of,
among other things, a holder being a "control person" of Parent or the Company
for purposes of Canadian federal, provincial or territorial securities laws).

        5.13 Directors and Officers. Parent agrees that all rights to
indemnification or exculpation existing as of the date of this Agreement in
favor of the directors, officers, employees and other agents of the Company in
the Company's Articles of Amalgamation or By-laws, or any agreement between the
Company and such persons that has been provided to Parent's counsel prior to the
date hereof, shall survive the Amalgamations and shall continue in full force
and effect and Parent agrees to assume, effective at the time of the Final
Closing, all such liability of the Company with respect to such indemnification.
This Section 5.13 shall survive the Amalgamations, is intended to benefit the
indemnified parties, shall be binding upon all successors and assigns of
Exchangeco and Parent, and shall be enforceable by the indemnified parties.

        5.14 Tax Matters. The parties agree that they will use their respective
commercially reasonable efforts to cause the Amalgamations, the Reorganization
and the issuance of the Exchangeable Shares in connection with the
Reorganization to the Company's shareholders who are Canadian resident taxpayers
to be tax-deferred for Canadian income tax purposes and not to take any action
reasonably expected to be inconsistent therewith.

                                   ARTICLE VI

                           CONDITIONS TO THE CLOSINGS

may only be waived by the mutual consent of Parent on behalf of the Parent
Companies and the Company:

                (i) Shareholder Approval. This Agreement and the Related
Agreements and the transactions contemplated hereby and thereby shall have been
approved and adopted by all of the shareholders option holders, warrant holders,
or other holders of interests to shares in the Company by the execution of the
Shareholder Implementation Agreement.

Agreement and the Related Agreements shall be in effect.

                (iii) Nasdaq Listing. The shares of Parent Common Stock issuable
to stockholders of the Company pursuant to the Exchangeable Share Provisions and
to the US Sellers in connection with the Initial Closing and such other shares

Second Amalgamation shall have been authorized for listing on the Nasdaq Stock
Market upon official notice of issuance.

terminate this Agreement under this Section 8.1(d) unless such breach is not
cured within thirty (30) days (but no cure period shall be required for a breach
which by its nature cannot be cured);

representation, warranty, covenant or agreement contained in this Agreement on
the part of Parent or Amalgamation Sub and as a result of such breach the

as provided in Section 9.1, this Agreement shall forthwith become void and,

        10.2 Interpretation. The words "include," "includes" and "including"
when used herein shall be deemed in each case to be followed by the words
"without limitation." The word "agreement" when used herein shall be deemed in
each case to mean any contract, commitment or other agreement, whether oral or
written, that is legally binding. As used in this Agreement, the phrase "to the
best of [a party's] knowledge," "to [a party's] knowledge," "[a party] is not
aware," and similar phrases shall mean the knowledge of such party, or of the
officers and directors of such party, after careful consideration of the matters
set forth in the representation that is so qualified and a reasonably diligent
review of all files, documents, agreements and other materials in such person's
possession or subject to his or her control. Unless otherwise expressly stated,
all references in this Agreement to "dollars" or "$" shall be deemed to be
references to the currency of the United States. The table of contents and
headings contained in this Agreement are for reference purposes only and shall
not affect in any way the meaning or interpretation of this Agreement.

        10.3 Counterparts. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other party, it being understood that all
parties need not sign the same counterpart.

        10.4 Entire Agreement; Assignment. This Agreement, the schedules and
Exhibits hereto, and the documents and instruments and other agreements among
the parties hereto referenced herein: (a) constitute the entire agreement among
the parties with respect to the subject matter hereof and supersede all prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter hereof; (b) except with respect to Sections 5.13,
8.2 and 8.3, are not intended to confer upon any other person any rights or
remedies hereunder; and (c) shall not be assigned by operation of law or
otherwise except as otherwise specifically provided, except that each of the
Parent Companies may assign its respective rights and delegate its respective
obligations hereunder to its respective affiliates.

        10.5 Severability. In the event that any provision of this Agreement or
the application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties hereto. The parties further agree to replace
such void or unenforceable provision of this Agreement with a valid and
enforceable provision that will achieve, to the extent possible, the economic,
business and other purposes of such void or unenforceable provision.

        10.6 Other Remedies. Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity upon
such party, and the exercise by a party of any one remedy will not preclude the
exercise of any other remedy.

        10.7 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of California, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof;
provided, however, that matters relating to the Amalgamations and the
Continuance and the corporate governance and organization of the Company shall
be governed by the laws of the Provinces of Ontario and Nova Scotia, as
applicable. Each of the parties hereto agrees that process may be served upon
them in any manner authorized by the laws of the State of California and the
Province of Ontario for such persons and waives and covenants not to assert or
plead any objection which they might otherwise have to such jurisdiction and
such process.

        10.8 Rules of Construction. The parties hereto agree that they have been
represented by counsel during the negotiation and execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule of
construction providing that ambiguities in an agreement or other document will
be construed against the party drafting such agreement or document.

        10.9 Specific Performance. The parties hereto agree that irreparable
damage would occur in the event that any of the provisions of this Agreement
were not performed in accordance with their specific terms or were otherwise
breached. It is accordingly agreed that the parties shall be entitled to an
injunction or injunctions to prevent breaches of this Agreement and to enforce
specifically the terms and provisions hereof in any court of the United States
or Canada or any state

                                      -51-

or province having jurisdiction, this being in addition to any other remedy to
which they are entitled at law or in equity.

        10.10 Share Legends. All certificates representing any of the shares of
Parent Common Stock to be issued pursuant to this Agreement shall have endorsed
thereon any legend required by Federal or state securities laws.

                                                               EXECUTION VERSION

                      AGREEMENT AND PLAN OF REORGANIZATION


        This AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is made and
entered into as of November 2, 1999, among Critical Path, Inc., a California
corporation ("Parent"), Wellfleet Acquisition Corp., a Delaware corporation and
a wholly-owned subsidiary of Parent ("Merger Sub"), and FaxNet Corporation, a
Delaware corporation (the "Company").

                                    RECITALS

        A. The Boards of Directors of each of the Company, Parent and Merger Sub
believe it is in the best interests of each company and their respective
shareholders that Parent acquire the Company through the statutory merger of
Merger Sub with and into the Company (the "Merger") and, in furtherance thereof,
have approved the Merger.

        B. Pursuant to the Merger, among other things, and subject to the terms
and conditions of this Agreement, all of the issued and outstanding shares of
capital stock of the Company ("Company Capital Stock") and all outstanding
options, warrants and other rights to acquire or receive shares of Company
Capital Stock shall be converted into the right to receive a combination of cash
and shares of Common Stock of Parent ("Parent Common Stock").

        C. Concurrently with the execution of this Agreement, and as a condition
and inducement to Parent's willingness to enter into this Agreement, certain
affiliates of the Company are entering into Voting Agreements in substantially
the form attached hereto as Exhibit A (the "Voting Agreements").

        D. A portion of the shares of Parent Common Stock otherwise issuable by
Parent in connection with the Merger shall be placed in escrow by Parent, the
release of which amount shall be contingent upon certain events and conditions.

        E. The parties intend, by executing this Agreement, to adopt a plan of
reorganization within the meaning of Section 368 of the Internal Revenue Code of
1986, as amended (the "Code").

        F. The parties intend for the Merger to be accounted for financial
accounting purposes as a purchase.

        NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable consideration,
intending to be legally bound hereby the parties agree as follows:

                                    ARTICLE I
                                   THE MERGER

        1.1 The Merger. At the Effective Time (as defined in Section 1.2) and
subject to and upon the terms and conditions of this Agreement and the
applicable provisions of the Delaware General Corporations Law ("Delaware Law"),
Merger Sub shall be merged with and into the Company, the separate corporate
existence of Merger Sub shall cease and the Company shall continue as the
surviving corporation and as a

<PAGE>   7

wholly-owned subsidiary of Parent. The Company as the surviving corporation
after the Merger is hereinafter sometimes referred to as the "Surviving
Corporation."

        1.2 Effective Time. Unless this Agreement is earlier terminated pursuant
to Section 8.1, the closing of the Merger (the "Closing") will take place as
promptly as practicable, but no later than five (5) business days, following
satisfaction or waiver of the conditions set forth in Article VI, at the offices
of Epstein Becker & Green, P.C., 75 State Street, Boston, Massachusetts, unless
another place or time is agreed to by Parent and the Company. The date upon
which the Closing actually occurs is herein referred to as the "Closing Date."
On the Closing Date, the parties hereto shall cause the Merger to be consummated
by filing a Certificate of Merger in substantially the form attached hereto as
Exhibit B (the "Certificate of Merger") with the Secretary of State of the State
of Delaware, in accordance with the relevant provisions of applicable law. The
date and time the Merger becomes effective in accordance with the provisions of
Delaware Law is the "Effective Time". The parties currently intend that the
Closing Date will occur on or prior to December 31, 1999.

        1.3 Effect of the Merger. At the Effective Time, the effect of the
Merger shall be as provided in the applicable provisions of Delaware Law.
Without limiting the generality of the foregoing, and subject thereto, at the
Effective Time, all the property, rights, privileges, powers and franchises of
the Company and Merger Sub shall vest in the Surviving Corporation, and all
debts, liabilities and duties of the Company and Merger Sub shall become the
debts, liabilities and duties of the Surviving Corporation.

        1.4 Certificate of Incorporation; Bylaws.

            (a) Unless otherwise determined by Parent prior to the Effective
Time, at the Effective Time, the Certificate of Incorporation of Merger Sub
shall be the Certificate of Incorporation of the Surviving Corporation until
thereafter amended as provided by law and such Certificate of Incorporation;
provided, however, that the name of the Surviving Corporation shall be FaxNet
Corporation.

            (b) The Bylaws of Merger Sub, as in effect immediately prior to the
Effective Time, shall be the Bylaws of the Surviving Corporation until
thereafter amended.

        1.5 Directors and Officers. The director(s) of Merger Sub immediately
prior to the Effective Time shall be the initial director(s) of the Surviving
Corporation, each to hold office in accordance with the Certificate of
Incorporation and Bylaws of the Surviving Corporation. The officers of Merger
Sub immediately prior to the Effective Time shall be the initial officers of the
Surviving Corporation, each to hold office in accordance with the Bylaws of the
Surviving Corporation.

        1.6 Shares to Be Issued; Cash to Be Paid; Effect on Capital Stock. The
number of shares of Parent Common Stock to be issued in exchange for the
acquisition by Parent of all outstanding Company Capital Stock, all unexpired
and unexercised options and warrants to acquire Company Capital Stock (other
than unvested Company Options (as defined below)) shall be 2,845,282 shares (the
"Aggregate Share Number"). No adjustment (i.e., credit) shall be made in the
exchange ratio as a result of any cash proceeds received by the Company from the
date hereof to the Closing Date pursuant to the exercise of options or warrants
to acquire Company Capital Stock as such adjustment has been taken into account
in calculating the Aggregate Share Number. The amount of cash that shall be paid
by Merger Sub in the Merger pursuant to this Agreement shall be $20,000,000 (the
"Aggregate Cash Consideration"). Notwithstanding anything herein to the
contrary, in the event that the Aggregate Cash Consideration would otherwise
equal 20% or more of the aggregate consideration to be received by the Company
stockholders as a result of the Merger

                                      -2-
<PAGE>   8

(excluding the portion of the Aggregate Share Number equal to the Escrow Amount
and the Special Escrow Amount, and assuming the Parent Common Stock constituting
the Aggregate Share Number has a value equal to 90% of the closing price for a
share of Parent Common Stock on the Nasdaq National Market on the trading day
immediately preceding the Closing Date), then, in such event, (x) the Aggregate
Cash Consideration shall be reduced to an amount equal to 19.99 % of the
aggregate consideration (determined as set forth above) and (y) the Aggregate
Share Number shall be increased by an amount equal to the amount by which the
Aggregate Cash Consideration is reduced, divided by the 15-day trailing average
closing price per share for a share of Parent Common Stock as reported on the
Nasdaq National Market for the fifteen trading days immediately preceding the
date of this Agreement.

                (i) Conversion of Company Common Stock. Subject to the terms and
conditions of this Agreement, as of the Effective Time, by virtue of the Merger
and without any action on the part of Merger Sub, the Company or the holder of
any shares of the Company Capital Stock, each share of Common Stock of the
Company ("Company Common Stock") issued and outstanding immediately prior to the
Effective Time (other than any shares of Company Common Stock to be canceled
pursuant to Section 1.6(b) and any Dissenting Shares (as defined and to the
extent provided in Section 1.7(a)) will be canceled and extinguished and be
converted automatically into the right to receive Parent Common Stock and cash
in the amount identified on Schedule 1.6(a) hereto upon surrender of the
certificate representing such share of Company Common Stock in the manner
provided in Section 1.8.

            (b) Cancellation of Parent-Owned and Company-Owned Stock. Each share
of Company Capital Stock owned by Merger Sub, Parent, the Company or any direct
or indirect wholly-owned subsidiary of Parent or of the Company immediately
prior to the Effective Time shall be canceled and extinguished without any
conversion thereof.

            (c) Stock Options and Warrants to Purchase Company Capital Stock.

                (i) At the Effective Time, all options to purchase Company
Common Stock then outstanding under the Company's 1996 Employee and Consultant
Stock Option Plan (the "Option Plan") shall be assumed by Parent in accordance
with provisions described below.

                    (1) At the Effective Time, each outstanding option to
purchase shares of Company Common Stock (each a "Company Option") under the
Option Plan or otherwise, whether vested or unvested, shall be, in connection
with the Merger, assumed by Parent. Each Company Option so assumed by Parent
under this Agreement shall continue to have, and be subject to, the same terms
and conditions set forth in the Option Plan and/or as provided in the respective
option agreements governing such Company Option immediately prior to the
Effective Time, except that (A) such Company Option shall be exercisable for
that number of whole shares of Parent Common Stock equal to the product of the
number of shares of Company Common Stock that were issuable upon exercise of
such Company Option immediately prior to the Effective Time multiplied by the
Option Exchange Ratio (as identified on Schedule 1.6(c) hereto) rounded down to
the nearest whole share and (B) the per share exercise price for the shares of
Parent Common Stock issuable upon exercise of such assumed Company Option shall
be equal to the quotient determined by dividing the exercise price per share of
Company Common Stock at which such Company Option was exercisable immediately
prior to the Effective Time by the Option Exchange Ratio, rounded up to the
nearest whole cent.

                    (2) It is the intention of the parties that the Company
Options assumed by Parent qualify following the Effective Time as incentive
stock options as defined in Section 422 of the

                                       -3-
<PAGE>   9

Code to the extent the Company Options qualified as incentive stock options
immediately prior to the Effective Time.

                    (3) Promptly following the Effective Time, Parent will issue
to each holder of an outstanding Company Option a document evidencing the
foregoing assumption of such Company Option by Parent.

                (ii) At the Effective Time, each outstanding warrant to purchase
Company Capital Stock (a "Company Warrant") that has not been fully exercised
shall be assumed by Parent. Each Warrant so assumed by Parent under this
Agreement shall continue to have, and be subject to, the same terms and
conditions set forth in the applicable warrant agreement immediately prior to
the Effective Time (including, without limitation, any repurchase rights or
vesting provisions), except that (i) each Company Warrant shall be exercisable
(or shall become exercisable in accordance with its terms) for that number of
whole shares of Parent Common Stock equal to the product of the number of shares
of Company Capital Stock that were issuable upon exercise of such Company
Warrant immediately prior to the Effective Time multiplied by the Warrant
Exchange Ratio (as identified on Schedule 1.6(c)), rounded to the nearest whole
number of shares of Parent Common Stock and (ii) the per share exercise price
for the Parent Common Stock issuable upon exercise of such assumed Company
Warrant shall be equal to the quotient determined by dividing the exercise price
per share of Company Capital Stock at which such Company Warrant was exercisable
immediately prior to the Effective Time by the Warrant Exchange Ratio, rounded
to the nearest whole cent.

            (d) Capital Stock of Merger Sub. Each share of Common Stock of
Merger Sub issued and outstanding immediately prior to the Effective Time shall
be converted into and exchanged for one validly issued, fully paid and
nonassessable share of Common Stock of the Surviving Corporation. Each stock
certificate of Merger Sub evidencing ownership of any such shares shall continue
to evidence ownership of such shares of capital stock of the Surviving
Corporation.

            (e) Adjustments to Exchange Ratio. The number of shares issuable
pursuant to this Section 1.6 shall be adjusted to reflect fully the effect of
any stock split, reverse split, stock dividend (including any dividend or
distribution of securities convertible into Parent Common Stock or Company
Capital Stock), reorganization, recapitalization or other like change with
respect to Parent Common Stock or Company Capital Stock occurring after the date
hereof and prior to the Effective Time.

            (f) Fractional Shares. No fraction of a share of Parent Common Stock
will be issued, but in lieu thereof, each holder of shares of Company Capital
Stock who would otherwise be entitled to a fraction of a share of Parent Common
Stock (after aggregating all fractional shares of Parent Common Stock to be
received by such holder) shall be entitled to receive from Parent an amount of
cash (rounded to the nearest whole cent) equal to the product of (i) such
fraction, multiplied by (ii) $45.096.

            (g) Aaron Eisendrath-Haelbig Warrant. For purposes of this Section
1.6, Parent and the Company agree that the Warrant dated March 31, 1999 issued
by the Company to Aaron Eisendrath-Haelbig shall be deemed to be null and void
as of the Effective Time. In the event that such Warrant is not terminated prior
to the six-month anniversary of the Closing Date, Parent shall be deemed to have
asserted a claim with respect to such warrant against that portion of the Escrow
Fund which would otherwise be released to the Company stockholders pursuant to
the Escrow Agreement on such six-month anniversary. Thereafter the shares of
Parent Common Stock representing such portion of the Escrow Fund shall continue
to be held in escrow pursuant to the Escrow Agreement.

                                      -4-
<PAGE>   10

            (h) Definitions.

                (i) Escrow Amount. The "Escrow Amount" shall be 266,099 shares
of Parent Common Stock.

                (ii) Special Escrow Amount. The "Special Escrow Amount" shall be
776,122 shares of Parent Common Stock.

        1.7 Dissenting Shares.

            (a) Notwithstanding any provision of this Agreement to the contrary,
any shares of Company Capital Stock held by a holder who has demanded and
perfected dissenters' rights for such shares in accordance with Delaware Law and
who, as of the Effective Time, has not effectively withdrawn or lost such
dissenters' rights ("Dissenting Shares"), shall not be converted into or
represent a right to receive Parent Common Stock pursuant to Section 1.6, but
the holder thereof shall only be entitled to such rights as are granted by
Delaware Law.

            (b) Notwithstanding the provisions of subsection (a), if any holder
of shares of Company Capital Stock who demands appraisal of such shares under
Delaware Law shall effectively withdraw or lose (through failure to perfect or
otherwise) the right to appraisal, then, as of the later of the Effective Time
and the occurrence of such event, such holder's shares shall automatically be
converted into and represent only the right to receive Parent Common Stock and
cash in lieu of fractional shares as provided in Section 1.6, without interest
thereon, upon surrender of the certificate representing such shares.

            (c) The Company shall give Parent (i) prompt notice of any written
demands for appraisal of any shares of Company Capital Stock, withdrawals of
such demands, and any other instruments served pursuant to Delaware Law and
received by the Company and (ii) the opportunity to participate in all
negotiations and proceedings with respect to demands for appraisal under
Delaware Law. The Company shall not, except with the prior written consent of
Parent, voluntarily make any payment with respect to any demands for appraisal
of capital stock of the Company or offer to settle or settle any such demands.

        1.8 Surrender of Certificates.

            (a) Exchange Agent. American Stock Transfer & Trust Company shall
serve as the exchange agent (the "Exchange Agent") in the Merger.

            (b) Parent and Merger Sub to Provide Cash and Common Stock. On or
prior to the Effective Time, Parent shall deliver to the Exchange Agent for
exchange in accordance with this Article I, the aggregate number of shares of
Parent Common Stock issuable pursuant to Section 1.6 in exchange for outstanding
shares of Company Capital Stock and shall cause Merger Sub to deliver to the
Exchange Agent an amount in cash equal to the Aggregate Cash Consideration;
provided that, on behalf of the holders of Company Capital Stock, Parent shall
deposit into an escrow account a number of shares of Parent Common Stock equal
to the Escrow Amount out of the aggregate number of shares of Parent Common
Stock otherwise issuable pursuant to Section 1.6 and this Section 1.8(b);
provided further, that, in the event that the Company shall have failed to
extend the term of the Amended and Restated Services Agreement dated March 12,
1997, as further amended to date, between the Company and U.S. West
Communications (the "U.S. West Agreement") to a period ending not earlier than
March 12, 2001, on substantially those terms set forth on Schedule 1.8(b), then,
on behalf of the holders of Company Capital Stock, Parent shall deposit into
such

                                      -5-
<PAGE>   11

escrow account an additional number of shares of Parent Common Stock equal to
the Special Escrow Amount out of the aggregate number of shares of Parent Common
Stock otherwise issuable pursuant to Section 1.6 and this Section 1.8(b). The
portion of the Escrow Amount and Special Escrow Amount, respectively,
contributed on behalf of each holder of Company Capital Stock shall be in
proportion to the aggregate number of shares of Parent Common Stock which such
holder would otherwise be entitled to receive under Section 1.6 by virtue of
ownership of outstanding shares of Company Capital Stock.

            (c) Exchange Procedures. Promptly after the execution of this
Agreement, the Company shall cause to be mailed to each holder of record of a
certificate or certificates (the "Certificates") which represent outstanding
shares of Company Capital Stock, (i) the Information Statement contemplated by
Section 5.1, which shall include an allocation of the cash and Parent Common
Stock consideration to be paid in exchange for the shares of Company Capital
Stock, together with a Stockholders' Letter Agreement appointing Keith Cooper
and Robert C. Roeper as "Stockholders' Representatives", (ii) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Exchange Agent and shall be in such form and have such other
provisions as Parent may reasonably specify) and (iii) instructions for
delivering the Certificates to Epstein Becker & Green, P.C. ("EBG") to be held
until the Effective Time and, at the Effective Time, surrendered in exchange for
cash and/or certificates representing shares of Parent Common Stock. Upon
surrender, by EBG pursuant to the letter of transmittal at the Effective Time or
by EBG or directly by the holder of such Certificate if after the Effective
Time, of a Certificate for cancellation to the Exchange Agent or to such other
agent or agents as may be appointed by Parent, together with such letter of
transmittal, duly completed and validly executed in accordance with the
instructions thereto, the holder of such Certificate shall be entitled to
receive in exchange therefor a certificate representing the number of whole
shares of Parent Common Stock (less the number of shares of Parent Common Stock,
if any, to be deposited in the Escrow Fund (as defined in Section 7.7 below) on
such holder's behalf pursuant to Section 7.7 hereof), and any cash consideration
to be received plus cash in lieu of fractional shares in accordance with Section
1.6, to which such holder is entitled pursuant to Section 1.6, and the
Certificate so surrendered shall forthwith be canceled. As soon as practicable
after the Effective Time, and subject to and in accordance with the provisions
of Article VII hereof, Parent shall cause to be distributed to the Escrow Agent
a certificate or certificates representing that number of shares of Parent
Common Stock equal to the Escrow Amount and Special Escrow Amount, if
appropriate, which shall be registered in the name of the Escrow Agent. Such
shares shall be beneficially owned by the holders on whose behalf such shares
were deposited in the Escrow Fund and shall be available to compensate Parent as
provided in Article VII. Until so surrendered, each outstanding Certificate
that, prior to the Effective Time, represented shares of Company Capital Stock
will be deemed from and after the Effective Time, for all corporate purposes,
other than the payment of dividends, to evidence the ownership of the number of
full shares of Parent Common Stock into which such shares of Company Capital
Stock shall have been so converted and the right to receive the applicable
amount of cash consideration for such shares of Company Capital Stock and cash
in lieu of the issuance of any fractional shares in accordance with Section 1.6.

            (d) Distributions With Respect to Unexchanged Shares. No dividends
or other distributions declared or made after the Effective Time with respect to
Parent Common Stock with a record date after the Effective Time will be paid to
the holder of any unsurrendered Certificate with respect to the shares of Parent
Common Stock represented thereby until the holder of record of such Certificate
shall surrender such Certificate. Subject to applicable law, following surrender
of any such Certificate, there shall be paid to the record holder of the
certificates representing whole shares of Parent Common Stock issued in exchange
therefor, without interest, at the time of such surrender, the amount of
dividends or other distributions with a

                                      -6-
<PAGE>   12

record date after the Effective Time theretofore paid with respect to such whole
shares of Parent Common Stock.

            (e) Transfers of Ownership. If any certificate for shares of Parent
Common Stock is to be issued in a name other than that in which the Certificate
surrendered in exchange therefor is registered, it will be a condition of the
issuance thereof that the Certificate so surrendered will be properly endorsed
and otherwise in proper form for transfer and that the person requesting such
exchange will have paid to Parent or any agent designated by it any transfer or
other taxes required by reason of the issuance of a certificate for shares of
Parent Common Stock in any name other than that of the registered holder of the
Certificate surrendered, or established to the satisfaction of Parent or any
agent designated by it that such tax has been paid or is not payable.

            (f) No Liability. Notwithstanding anything to the contrary in this
Section 1.8, none of the Exchange Agent, the Surviving Corporation (or any
officer or director thereof) or any party hereto shall be liable to a holder of
shares of Parent Common Stock or Company Capital Stock for any amount properly
paid to a public official pursuant to any applicable abandoned property, escheat
or similar law.

        1.9 No Further Ownership Rights in Company Capital Stock. All shares of
Parent Common Stock issued upon the surrender for exchange of shares of Company
Capital Stock in accordance with the terms hereof (including any cash paid in
respect thereof) shall be deemed to have been issued in full satisfaction of all
rights pertaining to such shares of Company Capital Stock, and there shall be no
further registration of transfers on the records of the Surviving Corporation of
shares of Company Capital Stock which were outstanding immediately prior to the
Effective Time. If, after the Effective Time, Certificates are presented to the
Surviving Corporation for any reason, they shall be canceled and exchanged as
provided in this Article I.

        1.10 Lost, Stolen or Destroyed Certificates. In the event any
certificates evidencing shares of Company Capital Stock shall have been lost,
stolen or destroyed, the Exchange Agent shall issue in exchange for such lost,
stolen or destroyed certificates, upon the making of an affidavit of that fact
by the holder thereof, such shares of Parent Common Stock, cash and cash for
fractional shares, if any, as may be required pursuant to Section 1.6; provided,
however, that Parent may, in its discretion and as a condition precedent to the
issuance thereof, require the owner of such lost, stolen or destroyed
certificates to deliver a bond in such sum as it may reasonably direct as
indemnity against any claim that may be made against Parent or the Exchange
Agent with respect to the certificates alleged to have been lost, stolen or
destroyed.

        1.11 Taking of Necessary Action; Further Action. If, at any time after
the Effective Time, any further action is necessary or desirable to carry out
the purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of the Company and Merger Sub, the officers and directors of the
Company and Merger Sub are fully authorized in the name of their respective
corporations or otherwise to take, and will take, all such lawful and necessary
action.

                                   ARTICLE II

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

        The Company hereby represents and warrants to Parent and Merger Sub,
subject to such exceptions as are specifically disclosed in the disclosure
letter (referencing the appropriate section number) supplied by the Company to
Parent (the "Company Schedules") and dated as of the date hereof, as follows:

        2.1 Organization of the Company. The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware. The Company has the corporate power to own its properties and to carry
on its business as now being conducted. The Company is duly qualified to do
business and in good standing as a foreign corporation in each jurisdiction in
which the failure to be so qualified would have a material adverse effect on the
business, assets (including intangible assets), financial condition or results
of operations of the Company; provided that in evaluating whether such an event
would constitute a material adverse effect, the effect shall be measured against
the business, assets (including intangible assets), financial condition and
results of operations of the Company on a normalized basis taking into account
the state of such matters over the twelve month period preceding the date of
this Agreement (hereinafter referred to as a "Material Adverse Effect"). The
Company has delivered a true, correct and complete copy of its Certificate of
Incorporation and Bylaws, each as amended to date, to Parent.

        2.2 Company Capital Structure.

            (a) The authorized capital stock of the Company consists of (i)
19,226,125 shares of Common Stock, of which 2,787,637 shares are issued and
outstanding, and (ii) 23,875 shares of Preferred Stock, of which 2,500 are
designated Series A Preferred, all of which are issued and outstanding, 3,125
shares are designated Series B Preferred, all of which are issued and
outstanding, 1,000 shares are designated Series C Preferred, all of which are
issued and outstanding, 5,250 shares are designated Series D Preferred Stock,
all of which are issued and outstanding, and 12,000 shares are designated Series
E Preferred, all of which are issued and outstanding. The Company Capital Stock
is held by the persons and in the amounts set forth on Schedule 2.2(a). All
outstanding shares of Company Capital Stock are duly authorized, validly issued,
fully paid and non-assessable and not subject to preemptive rights created by
statute, the Certificate of Incorporation or Bylaws of the Company or any

Incorporation or Bylaws of the Parent or Merger Sub or (ii) any mortgage,
indenture, lease, contract or other agreement filed by Parent with the
Securities and Exchange Commission or, to the knowledge of the Parent,
instrument, permit, concession, franchise, license, judgment, order, decree,
statute, law, ordinance, rule or regulation applicable to the Parent or Merger
Sub or its properties or assets, except in those instances where such Conflict
would have no Material Adverse Effect on the Parent and its subsidiaries taken
as a whole or have a Material Adverse Effect on Parent's or Merger Sub's ability
to consummate the transactions contemplated herein. No consent, waiver,
approval, order or authorization of, or registration, declaration or filing
with, any Governmental Entity or any third party (so as not to trigger any
Conflict), is required by or with respect to the Parent or Merger Sub in

of the transactions contemplated hereby, except for (i) the filing of the
Certification of Merger with the Secretary of State of the State of Delaware,
(ii) such consents, waivers, approvals, orders, authorizations, registrations,
declarations and filings as may be required under applicable federal and state
securities laws, and (iii) such other consents, waivers, authorizations,
filings, approvals and registrations which are set forth on Schedule 3.2.

        3.3 Capital Structure.

            (a) The authorized stock of Parent consists of 150,000,000 shares of
Common Stock, of which 43,429,673 shares were issued and outstanding as of
October 29, 1999, and 5,000,000 shares of Preferred Stock, none of which is
issued or outstanding as of October 29, 1999. The authorized capital stock of
Merger Sub consists of 1,000 shares of Common Stock, 1,000 shares of which, as
of the date hereof, are issued and outstanding and are held by Parent. All such
shares have been duly authorized, and all such issued and outstanding shares
have been validly issued, are fully paid and nonassessable and are free of any
liens or encumbrances other than any liens or encumbrances created by or imposed
upon the holders thereof.

            (b) The shares of Parent Common Stock to be issued pursuant to the
Merger will, when issued in accordance with the terms of this Agreement, be duly
authorized, validly issued, fully paid and nonassessable.

        3.4 SEC Documents; Parent Financial Statements. Parent has furnished or
made available to the Company true and complete copies of all reports or
registration statements filed by it with the U.S. Securities and Exchange
Commission (the "SEC")for all periods subsequent to January 1, 1999, all in the
form so filed (all of the foregoing being collectively referred to as the "SEC
Documents"). As of their respective filing dates, the SEC Documents complied in
all material respects with the requirements of the Exchange Act, and none of the
SEC Documents contained any untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements made therein not misleading, except to the extent corrected by a
subsequently filed document with the SEC. The financial statements of Parent,
including the notes thereto, included in the SEC Documents comply as to form in
all material respects with applicable accounting requirements and with the
published rules and regulations of the SEC with respect thereto, have been
prepared in accordance with generally accepted accounting principles
consistently applied (except as may be indicated in the notes thereto) and
present fairly the consolidated financial position of Parent at the dates
thereof and of its operations and cash flows for the periods then ended
(subject, in the case of unaudited statements, to normal audit adjustments).

        3.5 Representations Complete. None of the representations or warranties
made by Parent or Merger Sub (as modified by the Schedule 3.2), nor any
statement made in any certificate furnished by Parent pursuant to this
Agreement, or furnished by Parent specifically for inclusion in the Information
Statement prepared pursuant to Section 5.1, contains or will contain at the
Effective Time, any untrue statement of a

                                      -25-
<PAGE>   31

material fact, or omits or will omit at the Effective Time to state any material
fact necessary in order to make the statements contained herein or therein, in
the light of the circumstances under which they were made, not misleading.

        3.6 Regulatory Approvals. All consents, approvals, authorizations and
other requirements prescribed by any law, rule or regulation which must be
obtained or satisfied by the Parent or Merger Sub and which are necessary for
the consummation of the transactions contemplated by this Agreement have been,
or will be prior to the Closing, obtained and satisfied.

        3.7 Litigation. There are no legal actions, suits, arbitration or other
legal or administrative proceedings or governmental investigations pending or,
to Parent's knowledge, threatened, against the Parent or Merger Sub which would
impair the ability of the Parent or Merger Sub to consummate the transactions
contemplated herein.

        For the purposes of this Section 4.1, David Thatcher, or his designee,
shall have authority to provide written consent to any such action on behalf of
the Parent

        4.2 No Solicitation.

            (a) Subject to Section 4.2(b) below, until the earlier of (i) the
Effective Time and (ii) the date of termination of this Agreement pursuant to
the provisions of Section 8.1 hereof, the Company will not (nor will the Company
permit any of the Company's officers, directors, agents, representatives or
affiliates to) directly or indirectly, take any of the following actions with
any party other than Parent, Merger Sub, agents or representatives of the
Company and any of their designees: (a) solicit, conduct discussions with or
engage in negotiations with any person, relating to the possible acquisition of
the Company (whether by way of merger, purchase of capital stock, purchase of
assets or otherwise) or any material portion of its capital stock or assets, (b)
provide information with respect to it to any person, other than Parent,
relating to the possible acquisition of the Company (whether by way of merger,
purchase of capital stock, purchase of assets or otherwise) or any material
portion of its capital stock or assets, (c) enter into an agreement with any
person, other than Parent, providing for the acquisition of the Company (whether
by way of merger, purchase of capital stock, purchase of assets or otherwise) or
any material portion of its capital stock or assets or (d) make or authorize any
statement, recommendation or solicitation in support of any possible acquisition
of the Company (whether by way of merger, purchase of capital stock, purchase of
assets or otherwise) or any material portion of its capital stock or assets by
any person, other than by Parent. In addition to the foregoing, if the Company
receives prior to the Effective Time or the termination of this Agreement any
offer or proposal relating to any of the above, the Company shall immediately
notify Parent thereof, including information as to the identity of the offeror
or the party making any such offer or proposal and the specific terms of such
offer or proposal, as the case may be, and such other information related
thereto as Parent may reasonably request.

            (b) Nothing in this Agreement shall prevent the Board of Directors
of the Company from withholding, withdrawing, amending or modifying its
recommendation in favor of the Merger or taking any other action which is
prohibited by Section 4.2(a) if (i) a Superior Offer (as defined below) is made
to the Company and is not withdrawn, (ii) neither the Company nor any of its
representatives shall have violated any

                                      -28-
<PAGE>   34

of the restrictions set forth in Section 5.3, and (iii) the Board of Directors
of the Company concludes in good faith, after consultation with its outside
counsel, that, in light of such Superior Offer, the withholding, withdrawal,
amendment or modification of such recommendation is required in order for the
Board of Directors of the Company to comply with its fiduciary obligations to
the Company and the Company's stockholders under applicable law. Nothing
contained in this Section 4.2 shall limit the Company's obligation to hold and
convene a meeting of the Company's stockholders (regardless of whether the
recommendation of the Board of Directors of the Company shall have been
withdrawn, amended or modified). For purposes of this Agreement, "Superior
Offer" shall mean an unsolicited, bona fide written offer made by a third party
to consummate any of the following transactions: (i) a merger, consolidation,
business combination, recapitalization, liquidation, dissolution or similar
transaction involving the Company pursuant to which the stockholders of the
Company immediately preceding such transaction hold less than 51% of the equity
interest in the surviving or resulting entity of such transaction; (ii) a sale
or other disposition by the Company of assets (excluding inventory and used
equipment sold in the ordinary course of business) representing in excess of 50%
of the fair market value of the Company's business immediately prior to such
sale, or (iii) the acquisition by any person or group (including by way of a
tender offer or an exchange offer or issuance by the Company), directly or
indirectly, of beneficial ownership or a right to acquire beneficial ownership
of shares representing in excess of 50% of the voting power of the then
outstanding shares of capital stock of the Company, in each case on terms that
the Board of Directors of the Company determines, in its reasonable judgment
(based on a written opinion of an investment bank of nationally recognized
reputation) to be more favorable to Company stockholders from a financial point
of view than the terms of the Merger and the consideration of which reasonably
likely exceeds the value of the consideration in the Merger (after taking into
account all relevant factors, including any conditions to the Superior Offer,
the timing of the consummation of the transaction pursuant to the Superior
Offer, the risk of nonconsummation thereof and the need for any required
governmental or other consents, filings and approvals); provided, however, that
any such offer shall not be deemed to be a "Superior Offer" if any financing
required to consummate the transaction contemplated by such offer is not
committed and is not likely in the judgment of Company's Board of Directors to
be obtained by such third party on a timely basis.

        4.3 Investment Representation Statements. The Company will use its best
efforts to have all stockholders of the Company who are to receive any shares of
Parent Common Stock in connection with the Merger execute and deliver to Parent
a Parent Investment Representation Statement in substantially the form attached
hereto as Exhibit C.

                                    ARTICLE V
                              ADDITIONAL AGREEMENTS

        5.1 Information Statement; Stockholder Meeting.

            (a) As promptly as practicable after the execution of this
Agreement, the Company shall prepare, and Parent shall assist in preparing, an
information statement (the "Information Statement") relating to the solicitation
of the consent of the stockholders of the Company to the Merger. The Information
Statement shall substantially comply with the information requirements under to
Rule 502 promulgated under the Securities Act (except for 502(b)(3)) and an
investor suitability questionnaire. Parent shall provide to the Company and its
counsel for inclusion in the Information Statement such publicly available
information concerning Parent, its operations, capitalization, technology, share
ownership and other material as the Company or its counsel may reasonably
request. Each of Parent and the Company shall use its reasonable

                                      -29-
<PAGE>   35

best efforts to cause the Information Statement to be mailed to the Company's
stockholders at the earliest practicable time. Whenever any event occurs which
should be set forth in a supplement to the Information Statement, Parent or the
Company, as the case may be, shall promptly inform the other company of such
occurrence and cooperate in preparing such supplement.

            (b) The Company shall retain a "purchaser representative," as such
term is defined in Rule 501(h) under the Securities Act, to represent each
Company stockholder who is not an "accredited investor" as defined in Rule
501(a) under the Securities Act. The Company shall use its best efforts to
solicit and obtain the consent of its stockholders sufficient to approve the
Merger and this Agreement and to enable the Closing to occur as promptly as
practicable. The Company shall further use its best efforts to have each
investor who is not an accredited investor sign an acknowledgement that the
purchaser representative is such investor's purchaser representative in the
transactions contemplated hereby. The materials submitted to the Company's
stockholders, including the Information Statement, shall be subject to prior
review and approval by Parent and shall include the unanimous recommendation of
the Board of Directors of the Company in favor of the Merger and this Agreement.

            (c) The Information Statement submitted to the Company's
stockholders in connection with the Stockholders' Meeting shall include a
proposal to constitute and appoint Keith Cooper and Robert C. Roeper to act as
the agents, representatives and attorneys-in-fact for each stockholder (other
than holders of Dissenting Shares) for all purposes and with respect to all
matters arising under this Agreement. The powers and authority of the
Stockholders' Representatives shall include, but not be limited to, the power
and authority to give and accept notices as provided hereunder and carry out the
purposes and intent of this Agreement.

            (d) The Stockholders' Representatives shall each be entitled to rely
on any communication or document that they believe to be genuine. The
Stockholders' Representatives shall not be liable to any stockholder of the
Company for any action or omission on their respective parts except for fraud or
willful misconduct. In their capacity as a Stockholders' Representative, Keith
Cooper and Robert C. Roeper will be acting for the convenience of the
non-dissenting stockholders, without compensation, and, in such capacity, they
shall have no duties or liabilities beyond those expressly assumed by them in
this Agreement or as agreed with the Company stockholders. As the Stockholders'
Representatives, Keith Cooper and Robert C. Roeper shall not be required to make
any inquiry or investigation concerning any matter other than those expressly
contemplated hereunder, nor shall they, in such capacity, be deemed to have made
any representation or warranty of any kind to any person. The materials
submitted to the Company stockholders shall include proposed resolutions to be
adopted by the stockholders which shall include the approval of the Merger and
the transactions contemplated herein, the appointment of Keith Cooper and Robert
C. Roeper as Stockholders' Representatives, the establishment and approval of a
Contribution Amount to be utilized by the Stockholders' Representatives in their
capacity as such and in the defense of any claims for indemnification pursuant
to this Agreement, the approval of any payments to employees of the Company
pursuant to Section 280G of the Code and such other matters as the Company may
deem necessary or advisable to submit to the stockholders for approval. In the
event of the death, resignation or incapacity of either Keith Cooper or Robert
C. Roeper, a majority of the Company's stockholders shall elect a successor
stockholders' representative, who shall have all of the rights, powers and
duties of the Stockholders' Representatives set out herein.

        5.2 Access to Information. Subject to any applicable contractual
confidentiality obligations (which the Company shall use its best efforts to
cause to be waived) each party shall afford the others and its accountants,
counsel and other representatives, reasonable access during normal business
hours during the

                                      -30-
<PAGE>   36

period prior to the Effective Time to (a) all of its properties, books,
contracts, agreements and records, and (b) all other information concerning the
business, properties and personnel (subject to restrictions imposed by
applicable law) of it as the others may reasonably request. No information or
knowledge obtained in any investigation pursuant to this Section 5.2 shall
affect or be deemed to modify any representation or warranty contained herein or
the conditions to the obligations of the parties to consummate the Merger.

        5.3 Confidentiality. Each of the parties hereto hereby agrees to and
reaffirms the terms and provisions of that certain Confidentiality Agreement by
and between Parent and the Company dated as of August 13, 1999.

        5.4 Expenses. Whether or not the Merger is consummated, all fees and
expenses incurred in connection with the Merger including, without limitation,
all legal, accounting, financial advisory, investment banking, consulting and
all other fees and expenses of third parties ("Third Party Expenses") incurred
by Parent or the Company in connection with the negotiation and effectuation of
the terms and conditions of this Agreement and the transactions contemplated
hereby, shall be the obligation of Parent or the Company, as the case may be;
provided, however, that if the Merger is consummated, Parent shall pay at
closing an aggregate of $5,250,000 of the financial advisory fees plus up to and
not more than $50,000 of the out-of-pocket expenses of The Beacon Group incurred
by the Company.

the parties hereto, Parent and the Company shall release a jointly prepared
announcement describing the Merger. Except as aforesaid, unless otherwise
required by law (including, without limitation, securities laws) or, as to
Parent, by the rules and regulations of the National Association of Securities
Dealers, Inc., prior to the Effective Time, no disclosure (whether or not in
response to an inquiry) of the subject matter of this Agreement shall be made by
any party hereto unless approved by Parent and the Company prior to release,
which approval shall not be unreasonably withheld.

        5.6 Consents. The Company shall use its best efforts to obtain the
Required Consents.

        5.7 Company Warrants. The Company shall use its reasonable efforts to
cause the holders of the Company Warrants to exercise such Company Warrants
prior to the Effective Time.

        5.8 FIRPTA Compliance. On the Closing Date, the Company shall deliver to
Parent a properly executed statement in a form reasonably acceptable to Parent
for purposes of satisfying Parent's obligations under Treasury Regulation
Section 1.1445-2(c)(3).

        5.9 Reasonable Efforts. Subject to the terms and conditions provided in
this Agreement, each of the parties hereto shall use its reasonable efforts to

to be done, all things necessary, proper or advisable under applicable laws and
regulations to consummate and make effective the transactions contemplated
hereby, to obtain all necessary waivers, consents and approvals and to effect
all necessary registrations and filings and to remove any injunctions or other
impediments or delays, legal or otherwise, in order to consummate and make
effective the transactions contemplated by this Agreement for the purpose of
securing to the parties hereto the benefits contemplated by this Agreement;
provided that Parent shall not be required to agree to any divestiture by Parent
or the Company or any of Parent's subsidiaries or affiliates of shares of
capital stock or of any business, assets or property of Parent or its
subsidiaries or affiliates or the Company or its affiliates, or the imposition
of any material limitation on the ability of any of them to conduct their
businesses or to own or exercise control of such assets, properties and capital
stock.

                                      -31-
<PAGE>   37

        5.10 Notification of Certain Matters. The Company shall give prompt
notice to Parent, and Parent shall give prompt notice to the Company, of (i) the
occurrence or non-occurrence of any event, the occurrence or non-occurrence of
which is likely to cause any representation or warranty of the Company and
Parent or Merger Sub, respectively, contained in this Agreement to be untrue or
inaccurate in any material respect at or prior to the Effective Time except as
contemplated by this Agreement (including the Company Schedules) and (ii) any
failure of the Company or Parent, as the case may be, to comply with or satisfy
in any material respect any covenant, condition or agreement to be complied with
or satisfied by it hereunder; provided, however, that the delivery of any notice
pursuant to this Section 5.9 (including any description of any breaches of the
representation or warranties in this Agreement contained in an officer
certificate delivered pursuant to Section 6.2(a) or 6.3(a)) shall not limit or
otherwise affect any remedies available to the party receiving such notice.

        5.11 Additional Documents and Further Assurances. Each party hereto, at
the request of the other party hereto, shall execute and deliver such other
instruments and do and perform such other acts and things as may be reasonably
necessary or desirable for effecting completely the consummation of this
Agreement and the transactions contemplated hereby.

        5.12 Form S-8. Parent shall file a registration statement on Form S-8
under the Securities Act of 1933, as amended, for the shares of Parent Common
Stock issuable with respect to assumed Company Options within 60 days after the
Closing Date (the "S-8 Registration Statement"). Parent shall use its reasonable
best efforts to maintain the effectiveness of the S-8 Registration Statement
(and maintain the current status of the prospectus or prospectuses contained
therein) for so long as such options remain outstanding. The S-8 Registration
Statement and all amendments and supplements thereto will conform in all
respects with the requirements of the Securities Act of 1933, as amended, and
all rules and regulations promulgated thereunder.

        5.13 NMS Listing. On or prior to the Effective Time, Parent shall

best efforts to cause the Company's management and its independent auditors to
facilitate on a timely basis (i) the preparation of historical and pro forma
financial statements as required by Parent to comply with applicable SEC

papers, including the examination of selected interim financial statements and
data.

        5.15 Employee Benefits.

            (a) Parent shall take such reasonable actions as are necessary to
allow eligible employees of the Company to participate in the benefit programs
of Parent, or alternative benefits programs substantially comparable to those
applicable to employees of Parent on similar terms, as soon as practicable after
the Effective Time. Parent shall (i) on the Closing Date assume the Employment
Contracts listed on Schedule 2.12 and (ii) prior to the Closing Date have made
offers of employment to the Company's current employees on an at-will basis with
at least the same rate of pay and with the same benefits as similarly situated
employees of Parent are entitled.

            (b) Parent shall reserve an aggregate of $1,500,000 in cash (the
"Management Incentive Bonus"), which shall be distributed to those persons
identified and in such amounts as are set forth on

                                      -32-
<PAGE>   38

Schedule 5.15; provided that (i) such persons remain employed by the Company or
Parent for a period of not less than one year following the Closing, or have
been terminated by the Company or Parent without cause during such one year
period, and (ii) the Company's net revenues for the fiscal year ending December
31, 2000 are not less than 75% of projected net revenues as represented in the
Company's Descriptive Memorandum dated August 1999 ("Projected Revenues"). In
the event that the Company's net revenues for the fiscal year ending December
31, 2000 are less than 75% of Projected Revenues but not less than 60% of
Projected Revenues, the Management Incentive Bonus shall equal only $750,000. In
the event that any person on such Schedule 5.15 is not employed by the Company
or Parent on the 90-day anniversary of the Closing and not otherwise entitled to
receive any payment hereunder, Keith Cooper shall, in his sole discretion,
during such 90-day period, reallocate any amounts that would have been payable
pursuant to this Section 5.15 to such individuals among some or all of the
persons set forth on Schedule 5.15 provided that such individuals are otherwise
entitled to receive payment hereunder.

        5.16 Registration Rights. The holders of Company Capital Stock as of the
Effective Time (the "Holders") shall have registration rights with respect to
Parent Common Stock received in exchange therefor (the "Registrable Securities")
subject to the following terms and conditions:

            (a) Registration on Form S-3. Within five (5) business days after
Parent becomes a registrant entitled to use a Form S-3 registration statement or
any successor form thereto to register the resale (which shall not be through an
underwritten public offering) of the Registrable Securities, Parent shall use
reasonable best efforts to cause the Registrable Securities to be registered so
as to permit the resale thereof, and in connection therewith shall prepare and
file a Form S-3 registration statement or any successor form thereto providing
for an offering to be made on a continuous basis pursuant to Rule 415 under the
Securities Act (the "Registration Statement") with the SEC under the Securities
Act of 1933, as amended (the "Securities Act") to effect such registration
within ten (10) business days after the S-3 Date, and thereafter Parent shall
use its reasonable best efforts to cause the Registration Statement to be
declared effective under the Securities Act as soon as practicable after the
filing thereof; provided, however, that if Parent shall furnish to a
Stockholders' Representative a certificate signed by the Chief Executive Officer
of Parent stating that, in the good faith judgment of the Board of Directors or
Chief Executive Officer of Parent, it would be seriously detrimental to Parent
and its stockholders for the Registration Statement to be filed on or before the
date filing would otherwise be required, and it is therefore in the best
interests of Parent to defer the filing of the Registration Statement, then
Parent may delay the filing of the Registration Statement, once but not more
than once, for a period not in excess of thirty (30) days.

            (b) Expenses of Registration. Parent shall pay all Registration
Expenses (as hereafter defined) in connection with any registration,
qualification or compliance pursuant to this Section 5.15, and each Holder shall
pay all Selling Expenses (as hereafter defined) and other expenses that are not
Registration Expenses relating to the Registrable Securities resold by him or
her. For purposes of this Section 5.15(b), "Registration Expenses" shall mean
all expenses, except as otherwise stated below, incurred by Parent in complying
with Sections 5.15(a) and 5.15(c), including, without limitation, all
registration, qualification and filing fees, printing expenses, escrow fees,
fees and disbursements of counsel for Parent, blue sky fees and expenses and the
expense of any special audits incident to or required by any such registration.
For purposes of this Section 5.15(b), "Selling Expenses" shall mean all selling
discounts commissions and stock transfer or other Taxes applicable to the
Registrable Securities and all fees and disbursements of counsel for any Holder.

            (c) Registration Procedures. In the case of any registration
effected by Parent pursuant to this Section 5.15, Parent will keep each Holder
advised in writing as to the initiation of each registration and as to the
completion thereof. Parent will:

                                      -33-
<PAGE>   39

                (i) Use reasonable best efforts to keep such registration
effective until the earlier of (A) all Holders having completed the distribution
described in the registration statement relating thereto or (B) two years from
the Closing Date;

                (ii) Promptly prepare and file with the SEC such amendments and
supplements to the Registration Statement and the prospectus used in connection
with the Registration Statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by the Registration Statement;

                (iii) Furnish such number of prospectuses and other documents
incident thereto, including any amendment of or supplement to the prospectus, as
a Holder from time to time may reasonably request;

                (iv) Notify each Holder of Registrable Securities covered by the
Registration Statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in the Registration Statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing, and at the request of any such Holder, prepare and furnish to such
Holder a reasonable number of copies of a supplement to or an amendment of such
prospectus as may be necessary so that, as thereafter delivered to the
purchasers of such shares, such prospectus shall not include an untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in the light
of the circumstances then existing;

                (v) Cause all such Registrable Securities registered pursuant to
the Registration Statement to be listed on each securities exchange or quotation
system on which similar securities issued by Parent are then listed or quoted,
and in connection therewith, file with the Nasdaq National Market an application
for listing of additional shares with respect to the Registrable Securities;

                (vi) Provide a transfer agent and registrar for all Registrable
Securities registered pursuant to the Registration Statement and a CUSIP number
for all such Registrable Securities, in each case not later than the effective
date of the Registration Statement;

                (vii) Use its reasonable best efforts to register or qualify the
Registrable Securities covered by the Registration Statement under such other
securities or blue sky laws of such jurisdiction within the United States and
Puerto Rico as shall be reasonably appropriate for the distribution of the
Registrable Securities covered by the Registration Statement; provided, however,
that Parent shall not be required in connection therewith or as a condition
thereto to qualify to do business in or file a general consent to service of
process in any jurisdiction wherein it would not but for the requirements of
this paragraph be obligated to do so; and

Otherwise use its reasonable best efforts to comply with all applicable rules
and regulations of the SEC, and make available to its security holders, as soon
as reasonably practicable, an earnings statement covering a period of at least
twelve months, but not more than eighteen months, beginning with the first month
after the effective date of the Registration Statement, which earnings statement
shall satisfy the provisions of Section 11(a) of the Securities Act.

                                      -34-
<PAGE>   40

            (d) Information by Holder. Each Holder of Registrable Securities
shall furnish to Parent such information regarding such Holder and the
distribution proposed by such Holder as Parent may reasonably request in
connection with any registration, qualification or compliance referred to in
this Section 5.15, but only to the extent that such information is required in
order for Parent to comply with its obligations under all applicable securities
and other laws and to ensure that the Registration Statement relating to such
Registrable Securities conforms to the applicable requirements of the Securities
Act and the rules and regulations thereunder. Each Holder covenants that it will
promptly notify Parent of any changes in the information set forth in the
Registration Statement or otherwise provided by such Holder to Parent regarding
such Holder or such Holder's plan of distribution as a result of which the
Registration Statement or any prospectus relating to the Registrable Securities
contains or would contain an untrue statement of a material fact regarding such
Holder or its intended method of distribution of such Registrable Securities or
omits to state any material fact regarding such Holder or its intended method of
distribution of such Registrable Securities required to be stated therein or
necessary to make the statements therein, not misleading.

            (e) Indemnification and Contribution.

                (i)Parent agrees to indemnify and hold harmless each Holder from
and against any losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) to which such Holder may become subject (under
the Securities Act or otherwise) insofar as such losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) arise out of, or are
based upon, any untrue statement, alleged untrue statement, omission or alleged
omission of a material fact in the Registration Statement, any prospectus
included in the Registration Statement, or any amendment or supplement to the
Registration Statement or any such prospectus, and Parent will, as incurred,
reimburse such Holder for any legal or other expenses reasonably incurred in
investigating, defending or preparing to defend any such action, proceeding or
claim; provided, however, that Parent shall not be liable in any such case to
the extent that such loss, claim, damage or liability arises out of, or is based
upon (A) an untrue statement or alleged untrue statement made in such
Registration Statement in reliance upon and in conformity with written
information furnished to Parent by such Holder in an instrument executed by such
Holder and specifically stated to be for use in the preparation of the
Registration Statement, (B) the failure of such Holder to comply with any of the
covenants and agreements contained in Sections 5.15(f) or 5.15(h) hereof, or (C)
any untrue statement in any prospectus that is corrected in any subsequent
prospectus that was delivered to the Holder prior to the pertinent sale or sales
by the Holder.

                (ii) Each Holder, severally and not jointly, agrees to indemnify
and hold harmless Parent from and against any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) to which Parent may
become subject (under the Securities Act or otherwise) insofar as such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof)
arise out of, or are based upon (A) an untrue statement, alleged untrue
statement, omission or alleged omission of a material fact in the Registration
Statement, any prospectus included in the Registration Statement, or any
amendment or supplement to the Registration Statement or any such prospectus in
reliance upon and in conformity with written information furnished to Parent by
such Holder in an instrument executed by such Holder and specifically stated to
be for use in preparation of the Registration Statement, provided, however, that
no Holder shall be liable in any such case for any untrue statement included in
any Prospectus which statement has been corrected in a writing delivered to
Parent at least two business days before the sale from which such loss arose,
(B) the failure of such Holder to comply with any of the covenants and
agreements contained in Sections 5.15(f) or 5.15(h) hereof, or (C) any untrue
statement in any Prospectus that is corrected in any subsequent Prospectus that
was delivered to the Holder prior to the pertinent sale or sales by the Holder;
and each Holder, severally and not jointly, will, as incurred, reimburse Parent
for any legal or other expenses

                                      -35-
<PAGE>   41

reasonably incurred in investigating, defending or preparing to defend any such
action, proceeding or claim. In no event shall the amount payable by any Holder
to Parent pursuant to this Section 5.15(e)(ii) by reason of a sale of Parent
Common Stock by such Holder exceed the amount of the gross proceeds to such
Holder from the sale of Parent Common Stock from which such liability arose.

                (iii) Promptly after receipt by any indemnified person under
subsections (i) or (ii) above of a notice of a claim or the beginning of any
action in respect of which indemnity is to be sought against an indemnifying
person pursuant to this Section 5.15(e), such indemnified person shall notify
the indemnifying person in writing of such claim or of the commencement of such
action (provided, however, that no failure to provide such notice shall relieve
any indemnifying person of any liability hereunder except to the extent that
such indemnifying person is prejudiced thereby), and, subject to the provisions
hereinafter stated, in case any such action shall be brought against an
indemnified person and the indemnifying person shall have been notified thereof,
the indemnifying person shall be entitled to participate therein, and, to the
extent that it shall wish, to assume the defense thereof, with counsel
reasonably satisfactory to the indemnified person. After notice from the
indemnifying person to such indemnified person of the indemnifying person's
election to assume the defense thereof, the indemnifying person shall not be
liable to such indemnified person for any legal expenses subsequently incurred
by such indemnified person in connection with the defense thereof; provided,
however, that, if the indemnifying person shall propose that the same counsel
represent it and the indemnified person, and if counsel for the indemnified
person shall reasonably have concluded that there is an actual conflict of
interest posed by the representation proposed by the indemnifying person, the
indemnified person shall be entitled to retain its own counsel reasonably
satisfactory to the indemnifying person at the expense of such indemnifying
person; provided, however that if more than one indemnified person makes a claim
against an indemnifying person based on substantially similar facts, the
indemnifying person shall not be responsible for the fees of more than one
counsel for all indemnified persons whose claims are based on substantially
similar facts.

                (iv) If the indemnification provided for in this Section 5.15(e)
is unavailable to or insufficient to hold harmless an indemnified party under
subsection (i) or (ii) above in respect of any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) referred to therein,
then each indemnifying party shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (or actions in respect thereof), in such proportion as is
appropriate to reflect the relative fault of each such party, as well as any
other relevant equitable considerations. The relative fault shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by Parent on the one hand or a
Holder on the other and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
Parent and the Holders agree that it would not be just and equitable if
contribution pursuant to this Section 5.15(e)(iv) were determined by any method
of allocation which does not take account of the equitable considerations
referred to above in this Section 5.15(e)(iv). The amount paid or payable by an
indemnified party as a result of the losses, claims, damages, or liabilities (or
actions in respect thereof) referred to above in this Section 5.15(e)(iv) shall
be deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action,
proceeding or claim. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

                (v) The obligations of the Parent and the Holders under this
Section 5.15(e) shall be in addition to any liability which Parent and the
respective Holders may otherwise have and shall extend,

                                      -36-
<PAGE>   42

upon the same terms and conditions, to each director and officer of Parent or
any Holder, and to each person, if any, who controls Parent or any Holder within
the meaning of the Securities Act or the Exchange Act.

            (f) Restrictions on Transferability. The shares of Parent Common
Stock issued pursuant to the Merger (the "Restricted Shares") shall not be
transferable in the absence of (i) registration under the Securities Act or an
exemption therefrom, or (ii) registration or qualification under the provisions
of any applicable blue sky laws or an exemption therefrom.

            (g) Restrictive Legend. Each certificate representing Restricted
Shares shall bear substantially the following legends (in addition to any
legends required under applicable securities laws):

                THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED
FOR INVESTMENT PURPOSES ONLY AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933. THE SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH
REGISTRATION OR AN EXEMPTION THEREFROM.

                The legend contained in this Section 5.15(g) shall be removed
from a certificate in connection with any sale in compliance with and pursuant
to the Registration Statement, but shall not be removed in any other
circumstance without Parent's prior written consent (which consent shall not be
unreasonably withheld or delayed and shall be granted if such legend is no
longer appropriate).

            (h) Transfer of Shares After Registration.

                (i) Restriction. No Holder may make any sale of any Restricted
Shares except (A) in accordance with the Registration Statement, in which case
Holder must comply with the requirement of delivering a current prospectus, (B)
in accordance with Rule 144, or (C) pursuant to an exemption from the
registration requirements of the Securities Act, if accompanied by an opinion of
counsel that registration is not necessary, which opinion of counsel shall be
reasonably satisfactory to Parent.

                (ii) Right of Parent to Suspend Use of Registration Statement.
At any time Parent may refuse to permit any Holder to resell any Registrable
Securities pursuant to the Registration Statement; provided, however, that in
order to exercise this right, Parent must deliver a certificate in writing to
the Stockholders' Representative to the effect that, in the good faith judgement
of the Board of Directors or Chief Executive Officer of Parent, that a sale
pursuant to the Registration Statement in its then-current form would be
seriously detrimental to Parent and its stockholders and therefore it is in the
best interests of Parent to prohibit any sale under the Registration Statement
at that time. The Stockholders' Representative shall immediately notify the
holders of Registrable Securities of the receipt and contents of such
certificate. In no event shall such prohibition period exceed thirty (30)
calendar days, and provided further, however, that in no event shall Parent be
permitted to exercise this right (i) more than two times in any single calendar
year, or (ii) within thirty (30) calendar days of the expiration of such a
prohibition period or the expiration of the period during which Parent has
delayed the filing of a Registration Statement under Section 5.15(a).

            (i) Rule 144 Reporting. With a view to making available the benefits
of certain rules and regulations of the SEC which may at any time permit the
sale of the Registrable Securities to the public without registration, or
pursuant to a registration on Form S-3, Parent agrees to use its reasonable best
efforts to:

                                      -37-
<PAGE>   43

                (i)Make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act, at all times
after the Merger;

                (ii) File with the SEC in a timely manner all reports and other
documents required of Parent under the Securities Act and the Exchange Act; and

                (iii) So long as a Holder owns any Registrable Securities, to
furnish to that Holder forthwith upon request a written statement by Parent as
to its compliance with the reporting requirements of said Rule 144, and of the
Securities Act and the Exchange Act, a copy of the most recent annual or
quarterly report of Parent, and such other reports and documents of Parent as
such Holder may reasonably request in availing itself of any rule or regulation
of the SEC allowing such Holder to sell any such Registrable Securities without
registration.

            (j) Transfer of Registration Rights. The rights and obligations of
any Holder under this Section 5.15 may be assigned to a transferee or assignee
in connection with any transfer or assignment of Registrable Securities by a
Holder; provided that: (i) such transfer may otherwise be effected in accordance
with applicable securities laws, (ii) Parent is, within a reasonable time after
such transfer, furnished with written notice of the name and address of such
transferee or assignee and the securities with respect to which such
registration rights are being assigned under, (iii) each transferee shall agree
to be bound by all of the provisions of this Section 5.15; and (iv) such
assignment shall be effective only if immediately following such transfer the
further disposition of such Registrable Securities by the transferee or assignee
is restricted under the Securities Act.

        5.17 401(k) Plan. Parent and the Company acknowledge that they will work
together with respect to the transition of Company employees from the Company
401(k) plan. If Parent requests in writing at least fifteen (15) days prior to
Closing, Company shall cause its 401(k) plan to terminate effective as of the
day immediately preceding the Closing Date. From and after the Closing Date,
Parent shall provide for the participation by employees of the Surviving
Corporation in a 401(k) plan that is substantially similar to the 401(k) plan in
which employees of Parent participate. Parent shall recognize service with
Company for the purpose of eligibility to participate and vesting under such
401(k) plan.

        5.18 Promissory Note. In the event that all the conditions to closing
set forth in Sections 6.1, 6.2(a), (b) and (c), and 6.3 that are required to be
satisfied or waived have been satisfied or waived and Parent refuses to
consummate the Merger, the entire principal amount and interest owing under that
Promissory Note dated October 28, 1999 issued by the Company in favor of Parent
in the principal amount of $10,000,000 (the "Promissory Note") shall be forgiven
by Parent and the Company shall have no further obligation to repay the
principal or interest thereon.

        5.19 Company 1999 Bonus Plan. Simultaneous with the Closing of the
Merger, Parent shall pay to Epstein Becker & Green, P.C. ("EBG"), on behalf of
the Company, the amount of $7,500,000, representing payment in full of the
Company's obligations under its 1999 Bonus Plan. Prior to the Effective Time,
the Company shall provide to EBG irrevocable instructions pursuant to which EBG
shall thereafter promptly distribute such funds in accordance with such written
instructions, as contemplated by the terms of such 1999 Bonus Plan.

        5.20 Satisfaction of Company Liabilities. At Closing, Parent shall
satisfy the liabilities of the Company set forth on Schedule 5.20, together with
any other liabilities assumed by Parent in accordance with the Merger.

required to be reserved for issuance in connection with the Merger shall have
been authorized for listing on the Nasdaq Stock Market upon official notice of

of the Company to consummate the Merger and the transactions contemplated by

            (i) Termination of Agreement. If requested in writing by Parent at
least five business days prior to Closing, the Sales Agency Agreement dated July
14, 1998 between GN Comtext Limited, a company incorporated under the laws of
England, and the Company, pursuant to which GN Comtext Limited appointed the
Company to act as its sales representative for certain services within the
United States of America and Canada shall have terminated.

            (j) Repayment of Parent Loan. The Company shall repay in full
simultaneous with the Closing the outstanding principal and any interest thereon
under the Promissory Note; provided that in no event shall the Closing be deemed
to have occurred unless and until the outstanding principal and interest under
the Promissory Note shall have been repaid in full.

                                   ARTICLE VII

                   SURVIVAL OF REPRESENTATIONS AND WARRANTIES;
                             INDEMNIFICATION; ESCROW

        7.1 Survival of Representations and Warranties. All of the Company's
representations and warranties in this Agreement or in any instrument delivered
pursuant to this Agreement (each as modified by the Company Schedules) shall
survive the Merger and continue until 5:00 p.m., California time, on the six
month anniversary of the Closing Date, except that the representations and
warranties set forth in sections 2.8, 2.11 and 2.18 shall survive the Merger and
continue until 5:00 p.m., California time, on the twelve month anniversary of
the Closing Date.

        7.2 Obligation of the Company to Indemnify, Reimburse, etc. Subject to
the provisions of Section 7.4 hereof, the Company, its successors and assigns,
jointly and severally, shall indemnify, reimburse, defend, protect and hold
harmless Parent and Merger Sub and each of their successors and assigns and each
of their respective directors, officers, employees, affiliates, agents, and
their respective successors and assigns (each a "Parent Indemnitee") from and
against any claims, losses, liabilities, damages, causes of action, costs and
expenses (including reasonable attorney's, accountant's, consultant's and
expert's fees and expenses) (collectively "Losses") resulting from, directly or
indirectly, or based upon, any inaccuracy in or any breach of any
representation, warranty, covenant or agreement of the Company.

        7.3 Obligation of Parent to Indemnify, Reimburse, etc. Subject to the
provisions of Section 7.4 hereof, Parent and Merger Sub and their respective
successors and assigns, jointly and severally, shall indemnify, defend, protect
and hold harmless the Company and its successors and assigns and each of its

                                      -41-
<PAGE>   47

directors, officers, employees, affiliates, agents, and their respective
successors and assigns (each a "Company Indemnitee") from and against any Losses
resulting from, directly or indirectly, or based upon, any inaccuracy in or
breach of any representation, warranty, covenant or agreement of Parent or
Merger Sub.

        7.4 Claims for Indemnification. Whenever any claim shall arise for
indemnification under this Section 7, Parent or the Company, as the case may be,
seeking indemnification (the "Indemnified Party"), shall promptly notify (the
"Claim Notice") the party for whom indemnification is sought hereunder (the
"Indemnifying Party") of the claim and, when known, the facts constituting the
basis for such claim. In the event such Claim Notice is sent by Parent, Parent
shall deliver a copy of such Claim Notice to the Escrow Agent and the
Stockholders' Representatives. In the event of any such claim for
indemnification hereunder resulting from or in connection with any claim or
legal proceedings by a third party, the notice shall specify, if known, the
amount or an estimate of the amount of the liability arising therefrom. The
Indemnified Party shall not settle or compromise any claim by a third party for
which it is entitled to indemnification hereunder without the prior written
consent, which shall not be unreasonably withheld or delayed, of the
Indemnifying Party; provided, however, that if suit shall have been instituted
against the Indemnified Party and the Indemnifying Party shall not have taken
control of such suit after notification thereof as provided herein, the
Indemnified Party shall have the right to settle or compromise such claim upon
giving notice to the Indemnifying Party as provided in Section 7.5. In the event
that the Company constitutes the Indemnifying Party, all notices and consents
shall be given to, or by, the Stockholders' Representatives, who shall have the
power and authority to bind the Company and all of the Company's stockholders.

        7.5 Defense by the Indemnifying Party. In connection with any claim
which may give rise to indemnity hereunder resulting from or arising out of any
claim or legal proceeding by a person other than the Indemnified Party, the
Indemnifying Party, at its sole cost and expense, may, upon written notice to
the Indemnified Party, assume the defense of any such claim or legal proceeding
if the Indemnifying Party acknowledges to the Indemnified Party in writing the
obligation of the Indemnifying Party to indemnify the Indemnified Party with
respect to all elements of such claim. If the Indemnifying Party assumes the
defense of any such claim or legal proceeding, the Indemnifying Party shall, at
its sole cost and expense, take all steps necessary in the defense or settlement
thereof. The Indemnifying Party shall not consent to a settlement of, or the
entry of any judgment arising from, any such claim or legal proceeding, other
than the payment of money, unless such settlement includes a release of the
Indemnified Party from any and all claims arising from or related to such claim
or legal proceeding. The Indemnified Party shall be entitled to participate in
(but not control) the defense of any such action, with its own counsel and at
its own expense. If the Indemnifying Party does not assume the defense of any
such claim or litigation resulting therefrom within thirty (30) days after the
date such claim is made: (a) the Indemnified Party may defend against such claim
or litigation in such manner as it may deem appropriate, including, but not
limited to, settling such claim or litigation, after giving notice of the same
to the Indemnifying Party on such terms as the Indemnified Party may deem
appropriate, and (b) the Indemnifying Party shall be entitled to participate in
(but not control) the defense of such action, with its counsel and at its own
expense. If the Indemnifying Party thereafter seeks to question the manner in
which the Indemnified Party defended such third party claim or the amount or
nature of any such settlement, the Indemnifying Party shall have the burden to
prove by a preponderance of the evidence that the Indemnified Party did not
defend or settle such third party claim in a reasonably prudent manner. In the
event that the Company's stockholders constitute the Indemnifying Party, all
references herein to the Indemnifying Party shall be deemed to mean the
Stockholders' Representatives, who shall have the power and authority to bind
the Company and all of the Company's stockholders. All costs and expenses to be
borne by the Indemnifying Party, if the Indemnifying Party is the Company, shall
be borne severally by each of the Company's stockholders.

        7.6 Limits on Indemnification, Reimbursement, etc. Absent fraud or
willful misconduct of any party (for which there shall be no limitation of
liability of any party), no Parent Indemnitee and no Company Indemnitee shall
have any right to seek indemnification, reimbursement or defense under this
Agreement or the Escrow Agreement until Losses which would otherwise be
indemnifiable hereunder, and have been incurred by such party and other
indemnitees associated with or related to such party, exceed $1,000,000, and
then such indemnification or reimbursement shall only be to the extent that such
Losses are in excess of $500,000. For the purposes of the foregoing, only such
Losses that individually exceed $25,000 shall be counted towards the $1,000,000
threshold.

        7.7 Escrow Arrangements. Concurrent with the Effective Time, the Escrow
Amount and Special Escrow Amount, if appropriate, shall be placed in an escrow
fund (the "Escrow Fund"), to be governed by the terms of the Escrow Agreement.
That amount of shares of Parent Common Stock equal to the Escrow Amount placed
in the Escrow Fund shall be available to compensate Parent and its affiliates
for losses incurred by Parent and its affiliates in connection with breaches of
representations, warranties, or covenants contained herein or delivered pursuant
hereto. That amount of shares of Parent Common Stock equal to the Special Escrow
Amount placed in the Escrow Fund shall be paid to Parent in the event that,
prior to March 31, 2000, the Company shall fail to extend the term of the U.S.
West Agreement to a period ending not earlier than March 31, 2001, on
substantially the terms set forth on Schedule 1.8(b). The parties acknowledge
that after the Closing Date and absent fraud or willful misconduct, the maximum
amount that is payable under the indemnification obligation of the Company under
Section 7.2 is the Escrow Amount. The terms and conditions of the Escrow Fund
shall be set forth more fully in the Escrow Agreement.

        7.8 General Limitations. Unless this Agreement is terminated prior to
Closing, and except for any knowing and intentional, willful or fraudulent
breach of the representations and warranties or covenants contained in this
Agreement, no party hereto shall make any claim against another party other than
as set forth in this Article VII.

                                  ARTICLE VIII
                        TERMINATION, AMENDMENT AND WAIVER

        8.1 Termination. Except as provided in Section 8.2 below, this Agreement
may be terminated and the Merger abandoned at any time prior to the Effective
Time:

            (a) by mutual consent of the Company and Parent;

            (b) by Parent or the Company if: (i) the Effective Time has not
occurred by January 31, 2000 (provided that the right to terminate this
Agreement under this clause 8.1(b)(i) shall not be available to any party whose
willful failure to fulfill any obligation hereunder has been the cause of, or
resulted in, the failure of the Effective Time to occur on or before such date);
(ii) there shall be a final nonappealable order of a federal or state court in
effect preventing consummation of the Merger; or (iii) there shall be any
statute, rule, regulation or order enacted, promulgated or issued or deemed
applicable to the Merger by any governmental entity that would make consummation
of the Merger illegal;

            (c) by Parent if there shall be any action taken, or any statute,
rule, regulation or order enacted, promulgated or issued or deemed applicable to
the Merger, by any Governmental Entity, which would: (i) prohibit Parent's or
the Company's ownership or operation of any portion of the business of the

                                      -43-
<PAGE>   49

Company or (ii) compel Parent or the Company to dispose of or hold separate, as
a result of the Merger, any portion of the business or assets of the Company or
Parent;

            (d) by Parent if it is not in material breach of its obligations
under this Agreement and there has been a breach of any representation,
warranty, covenant or agreement contained in this Agreement on the part of the
Company and as a result of such breach the conditions set forth in Section
6.3(a) or 6.3(b), as the case may be, would not then be satisfied; provided,
however, that if such breach is curable by the Company within thirty (30) days
through the exercise of its reasonable best efforts, then for so long as the
Company continues to exercise such reasonable best efforts Parent may not
terminate this Agreement under this Section 8.1(d) unless such breach is not
cured within thirty (30) days of written notice of such breach (but no cure
period shall be required for a breach which by its nature cannot be cured);

            (e) by the Company if it is not in material breach of its
obligations under this Agreement and there has been a breach of any
representation, warranty, covenant or agreement contained in this Agreement on
the part of Parent or Merger Sub and as a result of such breach the conditions
set forth in Section 6.2(a) or 6.2(b), as the case may be, would not then be
satisfied; provided, however, that if such breach is curable by Parent or Merger
Sub within thirty (30) days through the exercise of its reasonable best efforts,
then for so long as Parent or Merger Sub continues to exercise such reasonable
best efforts the Company may not terminate this Agreement under this Section
8.1(e) unless such breach is not cured within thirty (30) days of written notice
of such breach (but no cure period shall be required for a breach which by its
nature cannot be cured);

            (f) by Parent upon a breach of Section 4.2 or the Company shall fail
to submit to its stockholders an Information Statement that includes the
unanimous recommendation of the Board of Directors of the Company in favor of
the Merger and this Agreement; and

            (g) by the Company or the Parent if the required approval of the
stockholders of the Company contemplated by this Agreement shall not have been
obtained by reason of the failure to obtain the required vote at a meeting of
the Company stockholders duly convened therefore or at any adjournment thereof;
provided, however, that the right to terminate this Agreement under this Section
8.1(g) shall not be available to the Company where the failure to obtain the
Company's stockholder approval shall have been caused by the action or failure
to act of the Company and such action or failure to act constitutes a material
breach by the Company of this Agreement.

        Where action is taken to terminate this Agreement pursuant to this
Section 8.1, it shall be sufficient for such action to be authorized by the
Board of Directors (as applicable) of the party taking such action.

        In the event that (i) this Agreement is terminated pursuant to Section
8.1 (other than Section 8.1(e)) of this Agreement, or (ii) the Company enters
into an agreement with any person, other than Parent, providing for the
acquisition of the Company (whether by way of merger, purchase of capital stock,
purchase of assets or otherwise) or any material portion of its capital stock or
assets, the Company shall pay on demand the principal and any interest thereon
due under the Promissory Note.

        8.2 Effect of Termination. In the event of termination of this Agreement
as provided in Section 8.1, this Agreement shall forthwith become void and,
except as set forth in Section 8.3, there shall be no liability or obligation on
the part of Parent, Merger Sub or the Company, or their respective officers,
directors or shareholders, provided that each party shall remain liable for any
breaches of this Agreement prior to its termination to the extent provided in
Section 8.3; and provided further that, the provisions of

                                      -44-
<PAGE>   50

Sections 5.3, this Section 8.2, Section 8.3 and Article IX of this Agreement
shall remain in full force and effect and survive any termination of this
Agreement.

        8.3 Fees and Expenses.

            (a) General. Except as set forth in this Section 8.3, all fees and
expenses incurred in connection with this Agreement and the transactions
contemplated hereby shall be paid by the party incurring such expenses whether
or not the Merger is consummated.

            (b) Break-up Fees Payments. In the event that this Agreement is
terminated by Parent or the Company, as applicable, pursuant to Sections 8.1(f)
or (g) or the Company fails to consummate the Merger and the transactions
contemplated by this Agreement after all of the conditions to Closing described
in Section 6.1 and 6.2 have been duly satisfied or waived, the Company shall
promptly, but in no event later than two days after the date of such
termination, pay Parent a fee equal to $5,000,000 in immediately available funds
(the "Termination Fee"). The parties hereto acknowledge that the agreements
contained in this Section 8.3(b) are an integral part of the transactions
contemplated by this Agreement and that, without these agreements, neither
Parent nor the Company would enter into this Agreement; accordingly, if the
Company fails to pay in a timely manner the amounts due pursuant to this Section
8.3(b), and, in order to obtain such payment, Parent makes a claim that results
in a judgment against the Company for the amount set forth in this Section
8.3(b), the Company shall pay to Parent its reasonable costs and expenses
(including attorneys' fees and expenses) in connection with such suit, together
with interest on the amount set forth in this Section 8.3(b) at the prime rate
of The Chase Manhattan Bank in effect on the date such payment was required to
be made. Payment of the fees described in this Section 8.3(b) shall not be in
lieu of damages incurred in the event of breach of this Agreement.

        8.4 Amendment. Except as is otherwise required by applicable law after
the shareholders of the Company approve this Agreement, this Agreement may be
amended by the parties hereto at any time by execution of an instrument in
writing signed on behalf of each of the parties hereto.

        8.5 Extension; Waiver. At any time prior to the Effective Time, Parent
and Merger Sub, on the one hand, and the Company, on the other, may, to the
extent legally allowed, (i) extend the time for the performance of any of the
obligations of the other party hereto, (ii) waive any inaccuracies in the
representations and warranties made to such party contained herein or in any
document delivered pursuant hereto, and (iii) waive compliance with any of the
agreements or conditions for the benefit of such party contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set forth in an instrument in writing signed on behalf of such
party.

        9.2 Interpretation. The words "include," "includes" and "including" when
used herein shall be deemed in each case to be followed by the words "without
limitation." The word "agreement" when used herein (except with respect to this
Agreement) shall be deemed in each case to mean any contract, commitment or
other agreement, whether oral or written, that is legally binding. As used in
this Agreement, the phrase "to [a party's] knowledge," and similar phrases shall
mean the knowledge of such party, or of the President, Chief Executive Officer,
Chief Financial Officer, Controller or any Vice President of such party after
careful consideration of the matters set forth in the representation that is so
qualified and a reasonably diligent review of all files, documents, agreements
and other materials in such person's possession or subject to his or her
control. The table of contents and headings contained in this Agreement are for
reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

        9.3 Counterparts. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other party, it being understood that all
parties need not sign the same counterpart.

        9.4 Entire Agreement; Assignment. This Agreement, the schedules and
Exhibits hereto, the documents and instruments and other agreements among the
parties hereto referenced herein, and the Confidentiality Agreement by and
between Parent and the Company dated August 13, 1999, (a) constitute the entire
agreement among the parties with respect to the subject matter hereof and
supersede all prior agreements and understandings, both written and oral, among
the parties with respect to the subject matter hereof; (b) are not intended to
confer upon any other person any rights or remedies hereunder; and (c) shall not
be assigned by operation of law or otherwise except as otherwise specifically
provided, except that Parent and Merger Sub may assign their respective rights
and delegate their respective obligations hereunder to their respective
affiliates.

        9.5 Severability. In the event that any provision of this Agreement or
the application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties hereto. The parties further agree to replace
such void or unenforceable provision of this Agreement with a valid and
enforceable provision that will achieve, to the extent possible, the economic,
business and other purposes of such void or unenforceable provision.

        9.6 Other Remedies. Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity upon
such party, and the exercise by a party of any one remedy will not preclude the
exercise of any other remedy.

        9.7 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.
Each of the parties hereto hereby consent and submit themselves to the
jurisdiction and venue of the State of Delaware for the purposes of any suit,
action or proceeding relating to this Agreement or the transactions contemplated
herein. Each of the parties hereto agrees that process may be served upon them
in any manner authorized by the laws of the State of Delaware for such persons
and waives and covenants not to assert or plead any objection which they might
otherwise have to such process. Each of the parties hereto also agrees not to
bring any action or proceeding arising out of or relating to this Agreement in
any court not located in the State of Delaware and hereby waives any defense of
inconvenient forum to the maintenance of any action or proceeding brought
therein in connection with this Agreement and waives any bond, surety or other
security that might be required of any other party with respect thereto.

        9.8 Rules of Construction. The parties hereto agree that they have been
represented by counsel during the negotiation and execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule of
construction providing that ambiguities in an agreement or other document will
be construed against the party drafting such agreement or document.

        9.9 Specific Performance. The parties hereto agree that irreparable
damage would occur in the event that any of the provisions of this Agreement
were not performed in accordance with their specific terms or were otherwise
breached. It is accordingly agreed that the parties shall be entitled to an
injunction or injunctions to prevent breaches of this Agreement and to enforce
specifically the terms and provisions hereof in any court of the United States
or any state having jurisdiction, this being in addition to any other remedy to
which they are entitled at law or in equity.

        9.10 Share Legends. All certificates representing any of the shares of
Parent Common Stock to be issued pursuant to this Agreement shall have endorsed
thereon any legend required by Federal or state securities laws.

                      AGREEMENT AND PLAN OF REORGANIZATION


        This AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is made and
entered into as of October 8, 1999, among Critical Path, Inc., a California
corporation ("Parent"), Xeti Acquisition Corp., a California corporation
("Merger Sub"), and Xeti, Inc., a California corporation (the "Company").

                                    RECITALS

        A. The Boards of Directors of each of the Company, Parent and Merger Sub
believe it is in the best interests of each company and their respective
shareholders that Parent acquire the Company through the statutory merger of
Merger Sub with and into the Company (the "Merger") and, in furtherance thereof,
have approved the Merger.

        B. Pursuant to the Merger, among other things, and subject to the terms
and conditions of this Agreement, all of the issued and outstanding shares of
capital stock of the Company ("Company Capital Stock") shall be converted into
the right to receive shares of Common Stock of Parent ("Parent Common Stock")
and cash, and all outstanding options and other rights to acquire or receive
shares of Company Capital Stock shall be assumed by the Parent.

        C. Concurrently with the execution of this Agreement, and as a condition
and inducement to Parent's willingness to enter into this Agreement, certain
affiliates of the Company are entering into Voting Agreements in substantially
the form attached hereto as Exhibit A (the "Voting Agreement").

        D. A portion of the shares of Exchangeable Stock otherwise issuable by
Parent in connection with the Merger shall be placed in escrow by Parent, the
release of which amount shall be contingent upon certain events and conditions.

        E. The parties intend, by executing this Agreement, to adopt a plan of
reorganization within the meaning of Section 368 of the Internal Revenue Code of
1986, as amended (the "Code").

        F. The parties intend for the Merger to be accounted for financial
accounting purposes as a purchase.

        NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable consideration,
intending to be legally bound hereby the parties agree as follows:

                                    ARTICLE I

                                   THE MERGER

        1.1 The Merger. At the Effective Time (as defined in Section 1.2) and
subject to and upon the terms and conditions of this Agreement and the
applicable provisions of the California General Corporations Law ("CGCL"),
Merger Sub shall be merged with and into the Company, the separate corporate
existence of Merger Sub shall cease and the Company shall continue as the
surviving corporation and as a wholly-owned subsidiary of Parent. The Company as
the surviving corporation after the Merger is hereinafter sometimes referred to
as the "Surviving Corporation."

        1.2 Effective Time. Unless this Agreement is earlier terminated pursuant
to Section 8.1, the closing of the Merger (the "Closing") will take place as
promptly as practicable, but no later than five (5) business days, following
satisfaction or waiver of the conditions set forth in Article VI, at the offices
of Wilson Sonsini Goodrich & Rosati, 650 Page Mill Road, Palo Alto, California,
unless another place or time is agreed to by Parent and the Company. The date
upon which the Closing actually occurs is herein referred to as the "Closing
Date." On the Closing Date, the parties hereto shall cause the Merger to be
consummated by filing a Agreement of Merger with the California Secretary of
State (the "Agreement of Merger"), in accordance with the relevant provisions of
applicable law. The date and time the Merger becomes effective in accordance
with the provisions of the CGCL is the "Effective Time". The parties currently
intend that the Closing Date will occur on or prior to November 15, 1999.

        1.3 Effect of the Merger. At the Effective Time, the effect of the
Merger shall be as provided in the applicable provisions of the CGCL. Without
limiting the generality of the foregoing, and subject thereto, at the Effective
Time, all the property, rights, privileges, powers and franchises of the Company
and Merger Sub shall vest in the Surviving Corporation, and all debts,
liabilities and duties of the Company and Merger Sub shall become the debts,
liabilities and duties of the Surviving Corporation.

        1.4 Articles of Incorporation; Bylaws.

            (a) Unless otherwise determined by Parent prior to the Effective
Time, at the Effective Time, the Articles of Incorporation of Merger Sub shall
be the Articles of Incorporation of the Surviving Corporation until thereafter
amended as provided by law and such Articles of Incorporation; provided that
Section 1 of the Articles of Incorporation of the Surviving Corporation shall be
amended to read "The name of the Corporation is XETI, Inc."

            (b) The Bylaws of Merger Sub, as in effect immediately prior to the
Effective Time, shall be the Bylaws of the Surviving Corporation until
thereafter amended.

        1.5 Directors and Officers. The director(s) of Merger Sub immediately
prior to the Effective Time shall be the initial director(s) of the Surviving
Corporation, each to hold office in accordance with the Articles of
Incorporation and Bylaws of the Surviving Corporation. The officers of Merger
Sub immediately prior to the Effective Time shall be the initial officers of the


                                      -2-
<PAGE>   6

Surviving Corporation, each to hold office in accordance with the Bylaws of the
Surviving Corporation.

        1.6 Maximum Shares to Be Issued; Effect on Capital Stock. No adjustment
shall be made in the number of shares of Parent Common Stock issued in the
Merger as a result of any cash proceeds received by the Company from the date
hereof to the Closing Date pursuant to the exercise of options to acquire
Company Capital Stock. Subject to the terms and conditions of this Agreement, as
of the Effective Time, by virtue of the Merger and without any action on the
part of Merger Sub, the Company or the holder of any shares of the Company
Capital Stock, the following shall occur:

            (a) Conversion of Company Common Stock. Each share of Common Stock
of the Company ("Company Common Stock") issued and outstanding immediately prior
to the Effective Time (other than any shares of Company Common Stock to be
canceled pursuant to Section 1.6(d) and any Dissenting Shares (as defined and to
the extent provided in Section 1.7(a)) will be canceled and extinguished and be
converted automatically into the right to receive upon surrender of the
certificate representing such share of Company Common Stock in the manner
provided in Section 1.8:

                (i) that number of shares of Parent Common Stock as is equal to
the Exchange Ratio (as defined in Schedule 1.6 attached hereto) plus the Common
Liquidation Exchange Ratio (as defined in Schedule 1.6 attached hereto) (subject
to readjustment in the event that a tax opinion is unavailable pursuant to
Section 6.1(c)); and

                (ii) cash in the amount of the Cash Rate (as defined in Schedule
1.6 attached hereto) plus the Common Liquidation Cash Amount (subject to
reduction for interim financing as set forth in Section 5.16) (subject to
readjustment in the event that a tax opinion is unavailable pursuant to Section
6.1(c)).

            (b) Conversion of Company Preferred Stock. Each share of Preferred
Stock of the Company ("Company Preferred Stock") issued and outstanding
immediately prior to the Effective Time (other than any shares of Company
Preferred Stock to be canceled pursuant to Section 1.6(d) and any Dissenting
Shares (as defined and to the extent provided in Section 1.7(a)) will be
canceled and extinguished and be converted automatically into the right to
receive upon surrender of the certificate representing such share of Company
Preferred Stock in the manner provided in Section 1.8:

                (i) that number of shares of Parent Common Stock as is equal to
the Exchange Ratio (as defined in Schedule 1.6 attached hereto) plus the Series
A Liquidation Exchange Ratio, Series B Liquidation Exchange Ratio, or Series C
Liquidation Exchange Ratio (as defined in Schedule 1.6 attached hereto) as
appropriate for the share so surrendered (subject to readjustment in the event
that a tax opinion is unavailable pursuant to Section 6.1(c)); and

                (ii) cash in the amount of the Cash Rate (as defined in Schedule
1.6 attached hereto) plus the Series A Liquidation Cash Amount, Series B
Liquidation Cash Amount, or


                                      -3-
<PAGE>   7

Series C Liquidation Cash Amount (as defined in Schedule 1.6 attached hereto) as
appropriate for the share so surrendered (subject to reduction for interim
financing as set forth in Section 5.16) (subject to readjustment in the event
that a tax opinion is unavailable pursuant to Section 6.1(c)).

            (c) Cancellation of Parent-Owned and Company-Owned Stock. Each share
of Company Capital Stock owned by Merger Sub, Parent, the Company or any direct
or indirect wholly owned subsidiary of Parent or of the Company immediately
prior to the Effective Time shall be canceled and extinguished without any
conversion thereof.

            (d) Stock Options. At the Effective Time, all options to purchase
Company Common Stock then outstanding under the Company's 1997 Stock Plan (the
"Option Plan"), or otherwise, shall be assumed by Parent in accordance with
provisions described below.

                (i) At the Effective Time, each outstanding option to purchase
shares of Company Common Stock (each a "Company Option") under the Option Plan
or otherwise, whether vested or unvested, shall be, in connection with the
Merger, assumed by Parent. Each Company Option so assumed by Parent under this
Agreement shall continue to have, and be subject to, the same terms and
conditions set forth in the Option Plan and/or as provided in the respective
option agreements governing such Company Option immediately prior to the
Effective Time, except that (A) such Company Option shall be exercisable for
that number of whole shares of Parent Common Stock equal to the product of the
number of shares of Company Common Stock that were issuable upon exercise of
such Company Option immediately prior to the Effective Time multiplied by the
Option Exchange Ratio (as defined in Schedule 1.6 attached hereto), rounded down
to the nearest whole number of shares of Parent Common Stock and (B) the per
share exercise price for the shares of Parent Common Stock issuable upon
exercise of such assumed Company Option shall be equal to the quotient
determined by dividing the exercise price per share of Company Common Stock at
which such Company Option was exercisable immediately prior to the Effective
Time by the Option Exchange Ratio, rounded up to the nearest whole cent (subject
to readjustment in the event that a tax opinion is unavailable pursuant to
Section 6.1(c)).

                (ii) It is the intention of the parties that the Company Options
assumed by Parent qualify following the Effective Time as incentive stock
options as defined in Section 422 of the Code to the extent the Company Options
qualified as incentive stock options immediately prior to the Effective Time.

                (iii) Promptly following the Effective Time, Parent will issue
to each holder of an outstanding Company Option a document evidencing the
foregoing assumption of such Company Option by Parent.

            (e) Capital Stock of Merger Sub. Each share of Common Stock of
Merger Sub issued and outstanding immediately prior to the Effective Time shall
be converted into and exchanged for one validly issued, fully paid and
nonassessable share of Common Stock of the Surviving Corporation. Each stock
certificate of Merger Sub evidencing ownership of any such shares shall continue
to evidence ownership of such shares of capital stock of the Surviving
Corporation.

or other like change with respect to Parent Common Stock or Company Capital
Stock occurring after the date hereof and prior to the Effective Time.

            (g) Fractional Shares. No fraction of a share of Parent Common Stock
will be issued, but in lieu thereof, each holder of shares of Company Capital
Stock who would otherwise be entitled to a fraction of a share of Parent Common
Stock (after aggregating all fractional shares of Parent Common Stock to be
received by such holder) shall be entitled to receive from Parent an amount of
cash (rounded to the nearest whole cent) equal to the product of (i) such
fraction, multiplied by (ii) the Signing Date Price.

any shares of Company Capital Stock held by a holder who has demanded and
perfected appraisal or dissenters' rights for such shares in accordance with the
CGCL and who, as of the Effective Time, has not effectively withdrawn or lost
such appraisal or dissenters' rights ("Dissenting Shares"), shall not be
converted into or represent a right to receive Parent Common Stock pursuant to
Section 1.6, but the holder thereof shall only be entitled to such rights as are
granted by the CGCL.

            (b) Notwithstanding the provisions of subsection (a), if any holder
of shares of Company Capital Stock who demands appraisal of such shares under
the CGCL shall effectively withdraw or lose (through failure to perfect or
otherwise) the right to appraisal, then, as of the later of the Effective Time
and the occurrence of such event, such holder's shares shall automatically be
converted into and represent only the right to receive Parent Common Stock and
the Cash Rate (and


                                      -6-
<PAGE>   10

cash in lieu of fractional shares) as provided in Section 1.6, without interest
thereon, upon surrender of the certificate representing such shares.

            (c) The Company shall give Parent (i) prompt notice of any written
demands for appraisal of any shares of Company Capital Stock, withdrawals of
such demands, and any other instruments served pursuant to the CGCL and received
by the Company and (ii) the opportunity to participate in all negotiations and
proceedings with respect to demands for appraisal under the CGCL. The Company
shall not, except with the prior written consent of Parent, voluntarily make any

        1.8 Surrender of Certificates.

            (a) Exchange Agent. U. S. Bank Trust shall act as exchange agent
(the "Exchange Agent") in the Merger.

            (b) Parent to Provide Common Stock and Cash. Promptly after the
Effective Time, Parent shall make available to the Exchange Agent for exchange
in accordance with this Article I, the aggregate number of shares of Parent
Common Stock issuable and the Cash Rate payable pursuant to Section 1.6 in
exchange for outstanding shares of Company Capital Stock; provided that, on
behalf of the holders of Company Capital Stock, Parent shall deposit into an
escrow account a number of shares of Parent Common Stock equal to the Escrow
Amount out of the aggregate number of shares of Parent Common Stock otherwise
issuable pursuant to Section 1.6. The portion of the Escrow Amount contributed
on behalf of each holder of Company Capital Stock shall be in proportion to the
aggregate number of shares of Parent Common Stock which such holder would
otherwise be entitled to receive under Section 1.6 by virtue of ownership of
outstanding shares of Company Capital Stock.

            (c) Exchange Procedures. Promptly after the Effective Time, the
Surviving Corporation shall cause to be mailed to each holder of record of a
certificate or certificates (the "Certificates") which immediately prior to the
Effective Time represented outstanding shares of Company Capital Stock whose
shares were converted into the right to receive shares of Parent Common Stock
and the Cash Rate pursuant to Section 1.6, (i) a letter of transmittal (which
shall specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Exchange
Agent and shall be in such form and have such other provisions as Parent may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for certificates representing shares of Parent
Common Stock. Upon surrender of a Certificate for cancellation to the Exchange
Agent or to such other agent or agents as may be appointed by Parent, together
with such letter of transmittal, duly completed and validly executed in
accordance with the instructions thereto, the holder of such Certificate shall
be entitled to receive in exchange therefor a certificate representing the
number of whole shares of Parent Common Stock (less the number of shares of
Parent Common Stock, if any, to be deposited in the Escrow Fund (as defined in
Section 7.5 below) on such holder's behalf pursuant to Section 7.5 hereof), and
the Cash Rate (plus cash in lieu of fractional shares) in accordance with
Section 1.6, to which such holder is entitled pursuant to Section 1.6, and the
Certificate so surrendered shall



                                      -7-
<PAGE>   11

forthwith be canceled. As soon as practicable after the Effective Time, and
subject to and in accordance with the provisions of Article VII hereof, Parent
shall cause to be distributed to the Escrow Agent a certificate or certificates
representing that number of shares of Parent Common Stock equal to the Escrow
Amount which shall be registered in the name of the Escrow Agent. Such shares
shall be beneficially owned by the holders on whose behalf such shares were
deposited in the Escrow Fund and shall be available to compensate Parent as
provided in Article VII. Until so surrendered, each outstanding Certificate
that, prior to the Effective Time, represented shares of Company Capital Stock
will be deemed from and after the Effective Time, for all corporate purposes,
other than the payment of dividends, to evidence the ownership of the number of
full shares of Parent Common Stock into which such shares of Company Capital
Stock shall have been so converted and the right to receive an amount in cash
calculated at the Cash Rate (plus cash in lieu of the issuance of any fractional
shares) in accordance with Section 1.6.

            (d) Distributions With Respect to Unexchanged Shares. No dividends
or other distributions declared or made after the Effective Time with respect to
Parent Common Stock with a record date after the Effective Time will be paid to
the holder of any unsurrendered Certificate with respect to the shares of Parent
Common Stock represented thereby until the holder of record of such Certificate
shall surrender such Certificate. Subject to applicable law, following surrender
of any such Certificate, there shall be paid to the record holder of the
certificates representing whole shares of Parent Common Stock issued in exchange
therefor, without interest, at the time of such surrender, the amount of
dividends or other distributions with a record date after the Effective Time
theretofore paid with respect to such whole shares of Parent Common Stock.

            (e) Transfers of Ownership. If any certificate for shares of Parent
Common Stock is to be issued in a name other than that in which the Certificate
surrendered in exchange therefor is registered, it will be a condition of the
issuance thereof that the Certificate so surrendered will be properly endorsed
and otherwise in proper form for transfer and that the person requesting such
exchange will have paid to Parent or any agent designated by it any transfer or
other taxes required by reason of the issuance of a certificate for shares of
Parent Common Stock in any name other than that of the registered holder of the
Certificate surrendered, or established to the satisfaction of Parent or any
agent designated by it that such tax has been paid or is not payable.

            (f) No Liability. Notwithstanding anything to the contrary in this
Section 1.8, none of the Exchange Agent, the Surviving Corporation or any party
hereto shall be liable to a holder of shares of Parent Common Stock or Company
Capital Stock for any amount properly paid to a public official pursuant to any
applicable abandoned property, escheat or similar law.

        1.9 No Further Ownership Rights in Company Capital Stock. All shares of
Parent Common Stock issued upon the surrender for exchange of shares of Company
Capital Stock in accordance with the terms hereof (including any cash paid in
respect thereof) shall be deemed to have been issued in full satisfaction of all
rights pertaining to such shares of Company Capital Stock, and there shall be no
further registration of transfers on the records of the Surviving Corporation of
shares of Company Capital Stock which were outstanding immediately prior to the
Effective Time.



                                      -8-
<PAGE>   12

If, after the Effective Time, Certificates are presented to the Surviving
Corporation for any reason, they shall be canceled and exchanged as provided in
this Article I.

        1.10 Lost, Stolen or Destroyed Certificates. In the event any
certificates evidencing shares of Company Capital Stock shall have been lost,
stolen or destroyed, the Exchange Agent shall issue in exchange for such lost,
stolen or destroyed certificates, upon the making of an affidavit of that fact
by the holder thereof, such shares of Parent Common Stock, the Cash Rate and
cash for fractional shares, if any, as may be required pursuant to Section 1.6;
provided, however, that Parent may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or

        4.2 No Solicitation. Until the earlier of (i) the Effective Time and
(ii) the date of termination of this Agreement pursuant to the provisions of
Section 8.1 hereof, the Company will not (nor will the Company permit any of the
Company's officers, directors, agents, representatives or affiliates to)
directly or indirectly, take any of the following actions with any party other
than Parent and its designees: (a) solicit, conduct discussions with or engage
in negotiations with any person, relating to the possible acquisition of the
Company (whether by way of merger, purchase of capital stock, purchase of assets
or otherwise) or any material portion of its or their capital stock or assets,
(b) provide information with respect to it, to any person, other than Parent,
relating to the possible acquisition of the Company (whether by way of merger,
purchase of capital stock, purchase of assets or otherwise) or any material
portion of its or their capital stock or assets, (c) enter into an agreement
with any person, other than Parent, providing for the acquisition of the Company

(d) make or authorize any statement, recommendation or solicitation in support
of any possible acquisition of the Company (whether by way of merger, purchase

addition to the foregoing, if the Company receives prior to the Effective Time
or the termination of this Agreement any offer or proposal relating to any of
the above, the Company shall immediately notify Parent thereof, including
information as to the identity of the offeror or the party making any such offer
or proposal and the specific terms of such offer or proposal, as the case may
be, and such other information related thereto as Parent may reasonably request.

                                    ARTICLE V

                              ADDITIONAL AGREEMENTS

        5.1 Registration Rights.

        In the event that the Parent Common Stock is issued to Company
shareholders (the "Holders") pursuant to a transaction which relies on the
registration exemption provided by Section 4(2) of the Securities Act (a "4(2)
Transaction"), the Holders shall have registration rights with respect to such
shares of Parent Common Stock (the "Registrable Securities") subject to the
following terms and conditions:

            (a) Registration on Form S-3. Parent shall use reasonable best
efforts to cause the Registrable Securities to be registered so as to permit the
resale thereof, and in connection therewith shall, within five (5) business days
after Parent becomes a registrant entitled to use a Form S-3 registration
statement or any successor form thereto to register the resale (which shall not
be through an underwritten public offering) of the Registrable Securities,
prepare and file a Form S-3 registration statement or any successor form thereto
providing for an offering to be made on a continuous basis under the Securities
Act (the "Registration Statement") with the SEC under the Securities Act of
1933, as amended (the "Securities Act") to effect such registration and
thereafter Parent shall use its reasonable best efforts to cause the
Registration Statement to be declared effective under the Securities Act as soon
as practicable after the filing thereof; provided, however,



                                      -30-
<PAGE>   34

that if Parent shall furnish to the Shareholders' Representative (as defined in
the Escrow Agreement) a certificate signed by the Chief Executive Officer of
Parent stating that, in the good faith judgment of the Board of Directors or
Chief Executive Officer of Parent, it would be seriously detrimental to Parent
and its shareholders for the Registration Statement to be filed on or before the
date filing would otherwise be required, and it is therefore in the best
interests of Parent to defer the filing of the Registration Statement, then
Parent may delay the filing of the Registration Statement, once but not more
than once, for a period not in excess of forty-five (45) days.

            (b) Piggy-Back Registration on Form S-1. If at any time prior to the
filing of the Registration Statement on Form S-3 described in Section 5.1(a) the
Parent shall determine to register any of its securities other than (a) a
registration relating solely to employee benefit plans, (b) a registration
relating solely to a SEC Rule 145 transaction or (c) a registration in which the
only Common Stock registered is Common Stock issuable upon conversion of
convertible debt securities that are also being registered, then the Parent will
comply with the provisions of this Section 5.1(b):

                (i) Notice of Registration. The Parent will promptly give to
each Holder a written notice thereof;

                (ii) Inclusion of Holder Shares. Include in such registration
(and any related qualification under state securities laws) and in any
underwriting involved therein all Registerable Securities specified in a written
request or requests made within 15 days after receipt of such written notice
from the Parent by any Holder; provided however, that if the managing
underwriter of the offering in connection with the registration advises the
Parent and/or the Holders that marketing factors require a limitation of the
number of shares to be underwritten, then the underwriter may exclude some or
all of the Registrable Securities proposed to be registered, but only so long as
the Registrable Securities, together with the securities that all other holders
of registration rights have elected to include in such registration, comprise at
least 15% of the offering.

            (c) Expenses of Registration. Parent shall pay all Registration
Expenses (as hereafter defined) in connection with any registration,
qualification or compliance pursuant to this Section 5.1, and each Holder shall
pay all Selling Expenses (as hereafter defined) and other expenses that are not
Registration Expenses relating to the Registrable Securities resold by him or
her. For purposes of this Section 5.1(c), "Registration Expenses" shall mean all
expenses, except as otherwise stated below, incurred by Parent in complying with
Sections 5.1(a), 5.1(b) and 5.1(d), including, without limitation, all
registration, qualification and filing fees, printing expenses, escrow fees,
fees and disbursements of counsel for Parent, blue sky fees and expenses, and
the expense of any special audits incident to or required by any such
registration. For purposes of this Section 5.1(c), "Selling Expenses" shall mean
all selling discounts commissions and stock transfer or other Taxes applicable
to the Registrable Securities and all fees and disbursements of one counsel for
all Holders.

            (d) Registration Procedures. In the case of any registration
effected by Parent pursuant to this Section 5.1, Parent will keep each Holder
advised in writing as to the initiation of each registration and as to the
completion thereof. Parent will:


                                      -31-
<PAGE>   35

                (i) Use reasonable best efforts to keep such registration
effective until the earlier of (A) all Holders having completed the distribution
described in the registration statement relating thereto or (B) two years from
the Closing Date;

                (ii) Promptly prepare and file with the SEC such amendments and
supplements to the Registration Statement and the prospectus used in connection
with the Registration Statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by the Registration Statement;

                (iii) Furnish such number of prospectuses and other documents
incident thereto, including any amendment of or supplement to the prospectus, as
a Holder from time to time may reasonably request;

                (iv) Subject to Section 5.1(i)(ii) hereof, notify each Holder of
Registrable Securities covered by the Registration Statement at any time when a
prospectus relating thereto is required to be delivered under the Securities Act
of the happening of any event as a result of which the prospectus included in
the Registration Statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in the light of the
circumstances then existing, and at the request of any such Holder, prepare and
furnish to such Holder a reasonable number of copies of a supplement to or an
amendment of such prospectus as may be necessary so that, as thereafter
delivered to the purchasers of such shares, such prospectus shall not include an
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein not misleading in
the light of the circumstances then existing;

                (v) Cause all such Registrable Securities registered pursuant to
the Registration Statement to be listed on each securities exchange or quotation
system on which similar securities issued by Parent are then listed or quoted,
and in connection therewith, file with the Nasdaq National Market an application
for listing of additional shares with respect to the Registrable Securities;

                (vi) Provide a transfer agent and registrar for all Registrable
Securities registered pursuant to the Registration Statement and a CUSIP number
for all such Registrable Securities, in each case not later than the effective
date of the Registration Statement;

                (vii) Use its reasonable best efforts to register or qualify the
Registerable Securities covered by the Registration Statement under such other
securities or blue sky laws of such jurisdiction within the United States and
Puerto Rico as shall be reasonably appropriate for the distribution of the
Registrable Securities covered by the Registration Statement; provided, however,
that Parent shall not be required in connection therewith or as a condition
thereto to qualify to do business in or file a general consent to service of
process in any jurisdiction wherein it would not but for the requirements of
this paragraph be obligated to do so; and

                (viii) Otherwise use its reasonable best efforts to comply with
all applicable rules and regulations of the SEC, and make available to its
security holders, as soon as reasonably


                                      -32-
<PAGE>   36

practicable, an earnings statement covering a period of at least twelve months,
but not more than eighteen months, beginning with the first month after the
effective date of the Registration Statement, which earnings statement shall
satisfy the provisions of Section 11(a) of the Securities Act.

            (e) Information by Holder. Each Holder of Registrable Securities
shall furnish to Parent such information regarding such Holder and the
distribution proposed by such Holder as Parent may reasonably request in
connection with any registration, qualification or compliance referred to in
this Section 5.1, but only to the extent that such information is required in
order for Parent to comply with its obligations under all applicable securities
and other laws and to ensure that the Registration Statement relating to such
Registrable Securities conforms to the applicable requirements of the Securities
Act and the rules and regulations thereunder. Each Holder covenants that it will
promptly notify Parent of any changes in the information set forth in the
Registration Statement or otherwise provided by such Holder to Parent regarding
such Holder or such Holder's plan of distribution as a result of which the
Registration Statement or any prospectus relating to the Registrable Securities
contains or would contain an untrue statement of a material fact regarding such
Holder or its intended method of distribution of such Registrable Securities or
omits to state any material fact regarding such Holder or its intended method of
distribution of such Registrable Securities required to be stated therein or
necessary to make the statements therein, not misleading.

            (f) Indemnification and Contribution.

                (i) Parent agrees to indemnify and hold harmless each Holder
from and against any losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) to which such Holder may become subject (under
the Securities Act or otherwise) insofar as such losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) arise out of, or are
based upon, any untrue statement, alleged untrue statement, omission or alleged
omission of a material fact in the Registration Statement, any prospectus
included in the Registration Statement, or any amendment or supplement to the
Registration Statement or any such prospectus, and Parent will, as incurred,
reimburse such Holder for any legal or other expenses reasonably incurred in
investigating, defending or preparing to defend any such action, proceeding or
claim; provided, however, that Parent shall not be liable in any such case to
the extent that such loss, claim, damage or liability arises out of, or is based
upon (A) an untrue statement or alleged untrue statement made in such
Registration Statement in reliance upon and in conformity with written
information furnished to Parent by such Holder in an instrument executed by such
Holder and specifically stated to be for use in the preparation of the
Registration Statement, (B) the failure of such Holder to comply with any of the
covenants and agreements contained in Sections 5.1(g) or 5.1(i) hereof, or (C)
any untrue statement in any prospectus that is corrected in any subsequent
prospectus that was delivered to the Holder prior to the pertinent sale or sales
by the Holder.

                (ii) Each Holder, severally and not jointly, agrees to indemnify
and hold harmless Parent from and against any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) to which Parent may
become subject (under the Securities Act or otherwise) insofar as such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof)



                                      -33-
<PAGE>   37

arise out of, or are based upon (A) an untrue statement, alleged untrue
statement, omission or alleged omission of a material fact in the Registration
Statement, any prospectus included in the Registration Statement, or any
amendment or supplement to the Registration Statement or any such prospectus in
reliance upon and in conformity with written information furnished to Parent by
such Holder in an instrument executed by such Holder and specifically stated to
be for use in preparation of the Registration Statement, provided, however, that
no Holder shall be liable in any such case for any untrue statement included in
any Prospectus which statement has been corrected in a writing delivered to
Parent at least two business days before the sale from which such loss arose,
(B) the failure of such Holder to comply with any of the covenants and
agreements contained in Sections 5.1(g) or 5.1(i) hereof, or (C) any untrue
statement in any Prospectus that is corrected in any subsequent Prospectus that
was delivered to the Holder prior to the pertinent sale or sales by the Holder;
and each Holder, severally and not jointly, will, as incurred, reimburse Parent
for any legal or other expenses reasonably incurred in investigating, defending
or preparing to defend any such action, proceeding or claim. In no event shall
the amount payable by any Holder to Parent pursuant to this Section 5.1(f)(ii)
by reason of a sale of Parent Common Stock by such Holder exceed the amount of
the gross proceeds to such Holder from the sale of Parent Common Stock from
which such liability arose.

                (iii) Promptly after receipt by any indemnified person under
subsections (i) or (ii) above of a notice of a claim or the beginning of any
action in respect of which indemnity is to be sought against an indemnifying
person pursuant to this Section 5.1(f), such indemnified person shall notify the
indemnifying person in writing of such claim or of the commencement of such
action (provided, however, that no failure to provide such notice shall relieve
any indemnifying person of any liability hereunder except to the extent that
such indemnifying person is prejudiced thereby), and, subject to the provisions
hereinafter stated, in case any such action shall be brought against an
indemnified person and the indemnifying person shall have been notified thereof,
the indemnifying person shall be entitled to participate therein, and, to the
extent that it shall wish, to assume the defense thereof, with counsel
reasonably satisfactory to the indemnified person. After notice from the
indemnifying person to such indemnified person of the indemnifying person's
election to assume the defense thereof, the indemnifying person shall not be
liable to such indemnified person for any legal expenses subsequently incurred
by such indemnified person in connection with the defense thereof; provided,
however, that, if the indemnifying person shall propose that the same counsel
represent it and the indemnified person, and if counsel for the indemnified
person shall reasonably have concluded that there is an actual conflict of
interest posed by the representation proposed by the indemnifying person, the
indemnified person shall be entitled to retain its own counsel reasonably
satisfactory to the indemnifying person at the expense of such indemnifying
person; provided, however that if more than one indemnified person makes a claim
against an indemnifying person based on substantially similar facts, the
indemnifying person shall not be responsible for the fees of more than one
counsel for all indemnified persons whose claims are based on substantially
similar facts.

                (iv) If the indemnification provided for in this Section 5.1(f)
is unavailable to or insufficient to hold harmless an indemnified party under
subsection (i) or (ii) above in respect of any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) referred to



                                      -34-
<PAGE>   38

therein, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages or
liabilities (or actions in respect thereof), in such proportion as is
appropriate to reflect the relative fault of each such party, as well as any
other relevant equitable considerations. The relative fault shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by Parent on the one hand or a
Holder on the other and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
Parent and the Holders agree that it would not be just and equitable if
contribution pursuant to this Section 5.1(f)(iv) were determined by any method
of allocation which does not take account of the equitable considerations
referred to above in this Section 5.1(f)(iv). The amount paid or payable by an
indemnified party as a result of the losses, claims, damages, or liabilities (or
actions in respect thereof) referred to above in this Section 5.1(f)(iv) shall
be deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action,
proceeding or claim. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

                (v) The obligations of the Parent and the Holders under this
Section 5.1(f) shall be in addition to any liability which Parent and the
respective Holders may otherwise have and shall extend, upon the same terms and
conditions, to each director and officer of Parent or any Holder, and to each
person, if any, who controls Parent or any Holder within the meaning of the
Securities Act or the Exchange Act.

            (g) Restrictions on Transferability. The shares of Parent Common
Stock issued or issuable pursuant to this Agreement in a 4(2) Transaction (the
"Restricted Shares") shall not be transferable in the absence of (i)
registration under the Securities Act or an exemption therefrom, (ii)
registration or qualification under the provisions of any applicable blue sky
laws or an exemption therefrom, or (iii) compliance with any term of this
Agreement. Parent shall be entitled to give stop transfer instructions to its
transfer agent with respect to the Restricted Shares in order to enforce the
foregoing restrictions.

            (h) Restrictive Legend. Each certificate representing Restricted
Shares shall bear substantially the following legends (in addition to any
legends required under applicable securities laws):

               THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
        INVESTMENT PURPOSES ONLY AND HAVE NOT BEEN REGISTERED UNDER THE
        SECURITIES ACT OF 1933. THE SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE
        ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM.

               ADDITIONALLY, THE TRANSFER OF THE SHARES REPRESENTED BY THIS
        CERTIFICATE IS SUBJECT TO CERTAIN RESTRICTIONS SPECIFIED IN THE
        AGREEMENT AND PLAN OF REORGANIZATION AMONG THE ISSUER,


                                      -35-
<PAGE>   39

        XETI ACQUISITION CORPORATION AND XETI , INC. DATED OCTOBER 8, 1999 (THE
        "AGREEMENT"), AND NO TRANSFER OF SHARES SHALL BE VALID OR EFFECTIVE
        ABSENT COMPLIANCE WITH SUCH RESTRICTIONS. ALL SUBSEQUENT HOLDERS OF THIS
        CERTIFICATE WILL HAVE AGREED TO BE BOUND BY CERTAIN OF THE TERMS OF THE
        AGREEMENT, INCLUDING SECTION 5.1 OF THE AGREEMENT. COPIES OF THE
        AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE
        REGISTERED HOLDER OF THIS CERTIFICATE TO THE SECRETARY OF THE COMPANY.

        The legend contained in this Section 5.1(h) shall be removed from a
certificate in connection with any sale in compliance with the terms of this
Agreement and pursuant to the Registration Statement, but shall not be removed
in any other circumstance without Parent's prior written consent (which consent
shall not be unreasonably withheld or delayed and shall be granted if such
legend is no longer appropriate).

            (i) Transfer of Shares After Registration.

                (i) Restriction. No Holder may make any sale of any Restricted
Shares except (A) in accordance with the Registration Statement, in which case
Holder must comply with the requirement of delivering a current prospectus, (B)
in accordance with Rule 144, or (C) pursuant to an exemption from the
registration requirements of the Securities Act, if accompanied by an opinion of
counsel that registration is not necessary, which opinion and counsel shall be
reasonably satisfactory to Parent. Such Restricted Shares are not transferable
on the books of Parent unless the certificate submitted to Parent's transfer
agent evidencing such Restricted Shares is accompanied by a separate
certificate, in form and substance reasonably satisfactory to Parent, executed
by an officer of, or other person duly authorized by, the Holder for purposes of
establishing compliance with this Agreement.

                (ii) Notice to Parent of Proposed Sale and Right of Parent to
Suspend Use of Registration Statement. If any Holder shall propose to sell any
Registrable Securities pursuant to the Registration Statement, it shall notify
Parent of its intent to do so at least three (3) full business days prior to
such sale. Such notice shall be deemed to constitute a representation that any
information previously supplied by such Holder (including without limitation the
information referred to in Section 5.1(e) hereof) is accurate as of the date of
such notice. At any time within such three (3) business-day period, Parent may
refuse to permit the Holder to resell any Registrable Securities pursuant to the
Registration Statement; provided, however, that in order to exercise this right,
Parent must deliver a certificate in writing to the Holder to the effect that a
delay in such sale is necessary because a sale pursuant to such Registration
Statement in its then-current form would not be in the best interests of Parent
and its shareholders. In no event shall such delay exceed forty-five (45)
calendar days, and provided further, however, that in no event shall Parent be
permitted to exercise this right more than three times in any single calendar
year.

            (j) Rule 144 Reporting. With a view to making available the benefits
of certain rules and regulations of the SEC which may at any time permit the
sale of the Registrable Securities to the



                                      -36-
<PAGE>   40

public without registration, or pursuant to a registration on Form S-3, the
Company agrees to use its reasonable best efforts to:

                (i)Make and keep public information available, as those terms

opinions. In the event that a tax opinion is unavailable because the aggregate
consideration consists of more than 20% cash (valuing the Parent Common Stock at

Signing Date Price); the aggregate consideration paid for all shares of Company
capital stock, but excluding payments made to options to acquire Company capital
stock or warrants to acquire Company capital stock should consist of no more

directors or shareholders, provided that each party shall remain liable for any
breaches of this Agreement prior to its termination; and provided further that,
the provisions of Sections 5.3 and 5.4 and Article IX of this Agreement shall

                                  OFFICE LEASE


                  THIS LEASE is made and entered into by and between Landlord
and Tenant as of the Lease Date. Landlord and Tenant hereby agree as follows:

         1.  Definitions.

                  1.1.  Terms Defined.  The following terms have the meanings
set forth below. Certain other terms have the meanings set forth in the Basic
Lease Information or elsewhere in this Lease.

                           Alterations: Alterations, additions or other
improvements to the Premises made by Tenant or its employees or contractors (but
not including the alterations, additions or other improvements, if any, made by
or on behalf of Tenant during the initial improvement of the Premises pursuant
to and governed by the provisions of the Work Letter).

                           Base Operating Expenses and Base Real Estate Taxes:
The Operating Expenses and the Real Estate Taxes paid or incurred by Landlord in
the Base Year.

                           Building: The office building, and surrounding
property, consisting of a four-story building located on the Land, commonly
known as 530 Folsom Street, San Francisco, California, and any additions to such
Building.

                           Escalation Rent: The total dollar increase, if any,
in Operating Expenses and in Real Estate Taxes, each as paid or incurred by
Landlord in each calendar year, or part thereof, after the Base Year, over the
amount of Base Operating Expenses and Base Real Estate Taxes. .For purposes of
determining Operating Expenses for the Base Year, since the Building will be
less than ninety-five percent (95%) occupied during the Base Year, Landlord
shall make an appropriate adjustment of the variable components of Operating
Expenses for that year, as reasonably determined by Landlord using sound
accounting and management principles, to determine the amount of Operating
Expenses that would have been incurred during such year if the Building had been
ninety-five percent (95%) occupied during the entire year. This amount shall be
considered to have been the amount of Operating Expenses for the Base Year. For
purposes hereof, "variable components" include only those component expenses
that are affected by variations in occupancy levels. For purposes of determining
Real Estate Taxes for the Base Year, Landlord shall make an appropriate
adjustment to the Real Estate Taxes for such year as reasonably determined by
Landlord using sound accounting and management principles, to determine the
amount of Real Estate Taxes that would have been incurred during such year if
the tenant improvements in the Building had been fully constructed and the Land,
the Building, and all tenant improvements in the Building had been fully
assessed for Real Estate Tax purposes.


                           Impositions: Taxes, assessments, charges, excises and
levies, business taxes, licenses, permits, inspection and other authorization
fees, transit development fees, assessments or charges for housing funds,
service payments in lieu of taxes and any other fees or charges of any kind at
any time levied, assessed, charged or imposed by any federal, state or local
entity, upon, measured by or reasonably attributable to the cost or value of
Tenant's equipment, furniture, fixtures or other personal property located in
the Premises, or the cost or value of any alterations, additions or other
improvements to the Premises made by or on behalf of Tenant during the initial
improvement of the Premises pursuant to and governed by the

per square foot of Rentable Area) and any subsequent Alterations. Impositions do
not include Real Estate Taxes, franchise, transfer, inheritance or capital stock
taxes, or income taxes measured by the net income of Landlord from all sources,

2000, then Tenant shall have the right to terminate this Lease by delivering
written notice to Landlord at any time before October 1, 2001, whereupon any
monies previously paid by Tenant to Landlord shall be reimbursed to Tenant.
Within five (5) days after the Possession Date, Landlord and Tenant shall
execute a Confirmation of Lease Term in the form as set forth in Exhibit E
attached to this Lease. Tenant's occupancy of all or any portion of the Premises
shall constitute Tenant's acceptance of the Premises in the condition called for
by this Lease. Tenant's occupancy of all or any portion of the Premises shall
constitute Tenant's acceptance of the Premises in the condition called for by
this Lease, subject to the punchlist items as described in the Work Letter.
Notwithstanding the foregoing, if the Possession Date occurs after June 1, 2000
as a result of events other than delays caused by the acts or omissions of
Tenant, or Tenant's contractors, employees or agents ("Tenant Delays"), then the
"Commencement Date" shall be a date calculated as follows: (i) two (2) weeks
after the Possession Date, plus (ii) the number of days by which the Possession
Date exceeds June 1, 2000, minus (iii) the number of days of delay that Landlord
is actually delayed in delivering the Premises to Tenant caused by Tenant
Delays.

                  3.2 Option to Extend.

                           3.2.1. Exercise of Option to Extend Term. If no
"Suspension Condition" (as hereinafter defined) exists at the time of Tenant's
exercise of the option to extend the Initial Term or at the commencement of the
Extended Term, as the case may be, Tenant shall have two (2) options (each an
"Extension Option") to extend the Initial Term for an additional period of five
(5) years each (each an "Extended Term"). To exercise Tenant's option with
respect to the Extended Term, Tenant shall give notice to Landlord not less than
two hundred ten (210) days prior to the expiration of the Initial Term, or the
first Extended Term ("Election Notice"). A "Suspension Condition" shall mean the
existence of any event or condition of default after expiration of any
applicable grace, notice or cure periods. Tenant shall have no right to exercise
the second Extension Option unless Tenant properly exercised the first Extension
Option.

                           3.2.2. Fair Market Rent. If Tenant properly and
timely exercises Tenant's option to extend pursuant to Section 3.2.1 above, such
extension shall be upon all of the same terms, covenants and conditions of this
Lease; provided, however, that the Base Rent applicable to the Premises for each
Extended Term shall be one hundred percent (100%) of the "Fair Market Rent" for
space comparable to the Premises as of the commencement of the applicable
Extended Term. "Fair Market Rent" shall mean the annual rental being charged for
first class space comparable to the Premises in buildings comparable to the
Building in the south of Market and financial districts of San Francisco, taking
into account location, parking, condition and improvements to the space and the
fact that Tenant is not entitled to rent concessions or a tenant improvement
allowance. All other terms and conditions of the Lease, which may be amended
from time to time by the parties in accordance with the provisions of the Lease,
shall remain in full force and effect and shall apply during each Extended Term,
as applicable, except that: (i) there shall be no further option to extend the
Term beyond a date ten (10) years after the expiration of the Initial Term, (ii)
there shall be no further rent concessions, and (iii) there shall be no tenant
improvement allowance or similar provisions.

                           3.2.3. Determination of Rent. Within thirty (30) days
after the date of the Election Notice, Landlord and Tenant shall negotiate in
good faith in an attempt to determine Fair Market Rent for the Extended Term. If
they are unable to agree within said thirty (30) day period, then the Fair
Market Rent shall be determined as provided in Section 3.2.4 below, unless on or
before such thirtieth (30th) day after the date of the Election Notice Tenant
provides Landlord with written notice of its election to revoke the Election
Notice and to not exercise its option to extend.

                           3.2.4. Appraisal. If it becomes necessary to
determine the Fair Market Rent for the Premises by appraisal, the real estate
appraiser(s) indicated in this Section 3.2.4, each of whom shall be



                                      -4-
<PAGE>   8

members of the Appraisal Institute and each of whom have at least five (5) years
experience appraising office space located in the vicinity of the Premises,
shall be appointed and shall act in accordance with the following procedures:

                           (i) If the parties are unable to agree on the Fair
Market Rent within the allowed time, either party may demand an appraisal by
giving written notice to the other party, which demand to be effective must
state the name, address and qualifications of an appraiser selected by the party
demanding the appraisal ("Notifying Party"). Within ten (10) days following the
Notifying Party's appraisal demand, the other party ("Non-Notifying Party")
shall either approve the appraiser selected by the Notifying Party or select a
second properly qualified appraiser by giving written notice of the name,
address and qualification of said appraiser to the Notifying Party. If the
Non-Notifying Party fails to select an appraiser within the ten (10) day period,
the appraiser selected by the Notifying Party shall be deemed selected by both
parties and no other appraiser shall be selected. If two (2) appraisers are
selected, they shall select a third appropriately qualified appraiser. If the
two (2) appraisers fail to select a third qualified appraiser, the third
appraiser shall be appointed by the then presiding judge of the county where the
Premises are located upon application by either party.

                           (ii) If only one appraiser is selected, that
appraiser shall notify the parties in simple letter form of its determination of
the Fair Market Rent for the Premises within fifteen (15) days following his or
her selection, which appraisal shall be conclusively determinative and binding
on the parties as the appraised Fair Market Rent.

                           (iii) If multiple appraisers are selected, the
appraisers shall meet not later than ten (10) days following the selection of
the last appraiser. At such meeting, the appraisers shall attempt to determine
the Fair Market Rent for the Premises as of the commencement date of the
Extended Term in question by the agreement of at least two (2) of the
appraisers.

                           (iv) If two (2) or more of the appraisers agree on
the Fair Market Rent for the Premises at the initial meeting, such agreement
shall be determinative and binding upon the parties hereto and the agreeing
appraisers shall forthwith notify both Landlord and Tenant of the amount set by
such agreement. If multiple appraisers are selected and two (2) appraisers are
unable to agree on the Fair Market Rent for the Premises, each appraiser shall
submit to Landlord and Tenant his or her respective independent appraisal of the
Fair Market Rent for the Premises, in simple letter form, within twenty (20)
days following appointment of the final appraiser. The parties shall then
determine the Fair Market Rent for the Premises by averaging the appraisals;
provided that any high or low appraisal, differing from the middle appraisal by
more than ten percent (10%) of the middle appraisal, shall be disregarded in
calculating the average.

                           (v) If only one (1) appraiser is selected, then each
party shall pay one-half (1/2) of the fees and expenses of that appraiser. If
three (3) appraisers are selected, each party shall bear the fees and expenses
of the appraiser it selects and one-half (1/2) of the fees and expenses of the
third appraiser.

                           3.2.5. Restriction on Assignment. The Extension
Option shall be personal to Critical Path or any Related Entity (defined below),
shall not be assignable or transferable, shall terminate upon any assignment of
the Premises other than to a Related Entity and or any sublease that results in
Tenant or a Related Entity retaining a portion of the Premises that is less than
fifty percent (50%) of the Rentable Area of the original Premises

                           3.2.6. Amendment to Lease. Immediately after the Fair
Market Rent has been determined, the parties shall enter into an amendment to
this Lease setting forth the Base Rent for the Extended Term and shall also
state the new Expiration Date of the Term of the Lease.



                                      -5-

                  3.3 Right to Terminate. Tenant shall have the right to
terminate this Lease effective at the end of the seventh year following the
Commencement Date (the "Early Termination Date") provided that Tenant delivers
written notice to Landlord at least 180 days prior to the Early Termination Date
and that on or before the Early Termination Date Tenant pays to Landlord a
termination fee in an amount equal to the unamortized (amortized on a straight
line basis over the Initial Term) Tenant Allowance (as defined in the Work
Letter) and brokerage fee paid by Landlord to the Brokers at the time this Lease
is executed and at the time the Tenant takes possession of the Premises.

         4.  Rent.

                  4.1. Obligation to Pay Base Rent. Tenant shall pay Base Rent
to Landlord, in advance, in equal monthly installments, commencing on the
Commencement Date, and thereafter on or before the first day of each calendar
month during the Term. If the Commencement Date and/or Expiration Date is other
than the first day of a calendar month, the installment of Base Rent for the
first and/or last fractional month of the Term shall be prorated on a daily
basis. Not less than thirty (30) days prior to the Commencement Date, Tenant
shall pay to Landlord the first month's Base Rent.

                  4.2. Manner of Rent Payment. All Rent shall be paid by Tenant
without notice, demand, abatement, deduction or offset (except as expressly set
forth herein), in lawful money of the United States of America, payable to
Landlord, at Landlord's Address as set forth in the Basic Lease Information, or
to such other person or at such other place as Landlord may from time to time
designate by notice to Tenant.

                  4.3. Additional Rent. All Rent not characterized as Base Rent
or Escalation Rent shall constitute additional rent, and if payable to Landlord
shall, unless otherwise specified in this Lease, be due and payable thirty (30)
days after Tenant's receipt of Landlord's invoice therefor.

                  4.4. Late Payment of Rent; Interest. Tenant acknowledges that
late payment by Tenant of any Rent will cause Landlord to incur administrative
costs not contemplated by this Lease, the exact amount of which are extremely
difficult and impracticable to ascertain based on the facts and circumstances
pertaining as of the Lease Date. Accordingly, if any Rent is not paid by Tenant
when due, a late charge equal to five percent (5%) of such Rent; provided,
however, that the following additional provisions shall apply to such late
charge: (i) the first late payment in any calendar year shall not result in any
late charge payment unless such payment of Rent is not received within two (2)
business days after Landlord's delivery of written notice to Tenant, and (ii) if
there are more than two (2) late payments of Rent by Tenant in any calendar
year, then the late charge for each subsequent late payment in such calendar
year shall be eight percent (8%). Any Rent, other than late charges, due
Landlord under this Lease, if not paid when due, shall also bear interest from
the date due until paid, at the lesser of the rate of ten percent (10%) per
annum and the highest rate legally permitted. The parties acknowledge that such
late charge and interest represent a fair and reasonable estimate of the
administrative costs and loss of use of funds Landlord will incur by reason of a
late Rent payment by Tenant, but Landlord's acceptance of such late charge
and/or interest shall not constitute a waiver of Tenant's default with respect
to such Rent or prevent Landlord from exercising any other rights and remedies
provided under this Lease, at law or in equity.

         5. Calculation and Payments of Escalation Rent. During each full or
partial calendar year of the Term subsequent to the Base Year, Tenant shall pay
to Landlord Escalation Rent in accordance with the following procedures:

                  5.1. Payment of Estimated Escalation Rent. During December of
the Base Year and



                                      -6-
<PAGE>   10

December of each subsequent calendar year, or as soon thereafter as practicable,
Landlord shall give Tenant notice of its estimate of Escalation Rent due for the
next ensuing calendar year. On or before the first day of each month during such
next ensuing calendar year, Tenant shall pay to Landlord in advance, in addition
to Base Rent, one-twelfth (1/12th) of such estimated Escalation Rent. In the
event such notice is given after December 31st of any year during the Term, (i)
Tenant shall continue to pay Escalation Rent on the basis of the prior calendar
year's estimate until the month after such notice is given, (ii) subsequent
payments by Tenant shall be based of the estimate of Escalation Rent set forth
in Landlord's notice, and (iii) with the first monthly payment of Escalation
Rent based on the estimate set forth in Landlord's notice, Tenant shall also pay
the difference, if any, between the amount previously paid for such calendar
year and the amount which Tenant would have paid through the month in which such
notice is given, based on Landlord's noticed estimate or, in the alternative, if
such amount previously paid by Tenant for such calendar year through the month
in which such notice is given exceeds the amount which Tenant would have paid
through such month based on Landlord's noticed estimate, Landlord shall credit
such excess amount against the next monthly payments of Escalation Rent due from
Tenant. If at any time Landlord reasonably determines that the Escalation Rent
for the current calendar year will vary from Landlord's estimate by more than
five percent (5%), Landlord may, by notice to Tenant not more than once a
calendar year, revise its estimate for such calendar year, and subsequent
payments by Tenant for such calendar year shall be based upon such revised
estimate. Notwithstanding anything to the contrary contained herein, Tenant may
pay the portion of Escalation Rent attributable to Real Estate Taxes as set
forth in Landlord's notice of its estimate of Escalation Rent on or before a
date thirty (30) days prior to the date such Real Estate Taxes are due, unless
Landlord notifies Tenant that its lender is requiring Landlord to escrow Real
Estate Taxes pursuant to a deed of trust encumbering the Premises.

                  5.2. Escalation Rent Statement and Adjustment. Within one
hundred twenty (120) days after the close of each calendar year, or as soon
thereafter as practicable, Landlord shall deliver to Tenant a statement of the
actual Escalation Rent for such calendar year, accompanied by a statement
prepared by Landlord showing in reasonable detail the Operating Expenses and the
Real Estate Taxes comprising the actual Escalation Rent. If Landlord's statement
shows that Tenant owes an amount less than the payments previously made by
Tenant for such calendar year, Landlord shall credit the difference first
against any sums then owed by Tenant to Landlord and then against the next
payment or payments of Rent due Landlord within thirty (30) days, except that if
a credit amount is due Tenant after termination of this Lease, Landlord shall
pay to Tenant any excess remaining after Landlord credits such amount against
any sums owed by Tenant to Landlord. If Landlord's statement shows that Tenant
owes an amount more than the payments previously made by Tenant for such
calendar year, Tenant shall pay the difference to Landlord within thirty (30)
days after delivery of the statement.

                  5.3. Proration for Partial Year. If this Lease terminates
other than on the last day of a calendar year (other than due to Tenant's
default), the amount of Escalation Rent for such fractional calendar year shall
be prorated on a daily basis. Upon such termination, Landlord may, at its
option, calculate the adjustment in Escalation Rent prior to the time specified
in Section 5.2 above. Tenant's obligation to pay Escalation Rent and Landlord's
obligation to reimburse excess amounts as set forth in Section 5.2, above, shall
survive the expiration or termination of this Lease.

                  5.4. Tenant's Right to Contest Taxes If Real Estate Taxes are
not contested by Landlord, Tenant shall have the right to contest such Taxes, at
no cost or expense to Landlord, by the appropriate proceedings diligently
contested in good faith. Notwithstanding such proceedings, the contested Real
Estate Taxes shall be promptly paid and discharged, unless such proceedings (and
where necessary the posting of any appropriate bond or other security) shall
operate to prevent or stay the collection of the Real Estate Taxes and secure
any accruing penalties or interest and such proceedings shall provide a cure of
Landlord's default in the payment of Real Estate Taxes required under any deed
of trust upon the



                                      -7-
<PAGE>   11

Premises. Landlord shall join Tenant in such proceedings, if necessary, provided
that Tenant pays all reasonable costs and expenses incurred by Landlord.

         6. Impositions Payable by Tenant. Tenant shall pay all Impositions
prior to delinquency. If billed directly to Tenant, Tenant shall pay such
Impositions and concurrently deliver to Landlord evidence of such payments. If
any Impositions are billed to Landlord or included in bills to Landlord for Real
Estate Taxes or other charges, then Tenant shall pay to Landlord all such
amounts within twenty (20) days after delivery of Landlord's invoice therefor.
If applicable law prohibits Tenant from reimbursing Landlord for an Imposition,
but Landlord may lawfully increase the Base Rent to account for Landlord's
payment of such Imposition, the Base Rent payable to Landlord shall be increased
to net to Landlord the same return without reimbursement of such Imposition as
would have been received by Landlord with reimbursement of such Imposition.
Tenant's obligation to pay Impositions which have accrued and remain unpaid upon
the expiration or earlier termination of this Lease shall survive the expiration
or earlier termination of this Lease.

         7.  Use of Premises.

                  7.1.  Permitted Use.  The Premises may only be used solely for
the Permitted Use and for no other use or purpose.

                  7.2. No Violation of Legal and Insurance Requirements. Tenant
shall not do or knowingly permit to be done, or bring or keep or knowingly
permit to be brought or kept, in or about the Premises, or any other portion of
the Building, anything which (i) is prohibited by or will in any way conflict
with any law, ordinance, rule or regulation; (ii) would invalidate or be in
conflict with the provisions of any insurance policy carried by Landlord or
Tenant on any portion of the Building or Premises, or any property therein; or
(iii) would cause a cancellation of any such insurance, increase the existing
rate of or affect any such Landlord's insurance (unless Tenant pays an increase
in premium), or subject Landlord to any liability or responsibility for injury
to any person or property. If Tenant does or knowingly permits anything to be
done which increases the cost of any of Landlord's insurance, or which results
in the need, in Landlord's reasonable judgment, for additional insurance by
Landlord or Tenant with respect to any portion of the Building or Premises, then
after prior written notice to Tenant of such action Tenant shall reimburse
Landlord, upon demand, for any such additional costs or the costs of such
additional insurance, and/or procure such additional insurance at Tenant's sole
cost and expense. Exercise by Landlord of such right to require reimbursement of
additional costs (including the costs of procuring of additional insurance)
shall not limit or preclude Landlord from prohibiting Tenant's impermissible use
of the Premises or from invoking any other right or remedy available to Landlord
under this Lease.

                  7.3. Compliance with Legal, Insurance and Life Safety
Requirements. Except as provided in clauses (i) through (iii) below, Tenant, at
its cost and expense, shall promptly comply with all laws, ordinances, rules,
regulations, orders and other governmental requirements, the requirements of any
board of fire underwriters or other similar body, any directive or occupancy
certificate issued pursuant to any law by any public officer or officers, the
provisions of all recorded documents affecting any portion of the Building and
all life safety programs, procedures and rules implemented or promulgated by
Landlord in its reasonable judgement pertaining to Tenant's use of the Premises
in order to comply with applicable laws, ordinances, rules, regulations, orders
or governmental requirements or requirements of insurance underwriters ("Laws").
Tenant shall not, however, be required to comply with Laws requiring Tenant to
make structural changes or capital improvements to the Premises unless
necessitated, in whole or in part, by (i) Tenant's particular use or occupancy
of the Premises or (ii) Alterations (excluding any alterations, additions or
other improvements to the Premises made by or on behalf of Tenant during the



                                      -8-
<PAGE>   12

initial improvement of the Premises pursuant to the Work Letter).

                  7.4. No Nuisance. Tenant shall not (i) do or permit anything
to be done in or about the Premises, or any other portion of the Building, which
would injure or annoy, or obstruct or interfere with the rights of, Landlord or
other occupants of the Building, or others lawfully in or about the Building;
(ii) use or allow the Premises to be used in any manner inappropriate for a
Class A office building, or for any improper or objectionable purposes; or (iii)
cause, maintain or permit any nuisance or waste in, on or about the Premises, or
any other portion of the Building.

                  7.5.  Hazardous Substances.  The term "Hazardous Substances"
as used in the Lease, is defined as follows:

         Any element, compound, mixture, solution, particle or substance, which
         presents danger or potential danger of damage or injury to health,
         welfare or to the environment including, but not limited to: (i) those
         substances which are inherently or potentially radioactive, explosive,
         ignitable, corrosive, reactive, carcinogenic or toxic and (ii) those
         substances which have been recognized as dangerous or potentially
         dangerous to health, welfare or to the environment by any federal,
         municipal, state, county or other governmental or quasi-governmental
         authority and/or any department or agency thereof.

                  Tenant represents and warrants to Landlord and agrees that at
all times during the term of this Lease and any extensions or renewals thereof,
Tenant shall:

                  (i) promptly comply at Tenant's sole cost and expense, with
         all laws, orders, rules, regulations, certificates of occupancy, or
         other requirements, as the same now exist or may hereafter be enacted,
         amended or promulgated, of any federal, municipal, state, county or
         other governmental or quasi-governmental authorities and/or any
         department or agency thereof relating to the manufacturing, processing,
         distributing, using, producing, treating, storing (above or below
         ground level), disposing or knowingly allowing to be present (the
         "Environmental Activity") of Hazardous Substances in or about the
         Premises (each, an "Environmental Law", and all of them, "Environmental
         Laws") to the extent Tenant is responsible for the presence of such
         Hazardous Substances.

                  (ii) indemnify and hold Landlord, its agents and employees,
         harmless from any and all demands, claims, causes of action, penalties,
         liabilities, judgments, damages (including consequential damages) and
         expenses including, without limitation, court costs and reasonable
         attorneys' fees incurred by Landlord as a result of (a) Tenant's
         failure or delay in properly complying with any Environmental Law as
         required by clause (i) above, or (b) any adverse effect which results
         from the Environmental Activity by Tenant, Tenant's subtenants or any
         of their respective agents, employees or contractors, whether Tenant or
         Tenant's subtenants or any of their respective agents, employees,
         contractors or invitees has caused such Environmental Activity, with or
         without Tenant's consent, or either intentionally or unintentionally.
         If any action or proceeding is brought against Landlord, its agents or
         employees by reason of any such claim, Tenant, upon notice from
         Landlord, will defend such claim at Tenant's expense with counsel
         reasonably satisfactory to Landlord. This indemnity obligation by
         Tenant of Landlord will survive the expiration or earlier termination
         of this Lease.

                  (iii) promptly disclose to Landlord by delivering, in the
         manner prescribed for delivery of notice in this Lease, a copy of any
         forms, submissions, notices, reports, or other written documentation
         (each, a "Communication") relating to any Environmental Activity,
         whether any



                                      -9-
<PAGE>   13

         such Communication is delivered to Tenant or any of its subtenants or
         is requested of Tenant or any of its subtenants by any federal,
         municipal, state, county or other government or quasi-governmental
         authority and/or any department or agency thereof.

                  (iv) in the event there is a release of any Hazardous
         Substance as a result of or in connection with any Environmental
         Activity by Tenant or any of Tenant's subtenants or any of their
         respective agents, employees, contractors or invitees, which must be
         remediated under any Environmental Law, Landlord shall perform the
         necessary remediation; and Tenant shall reimburse Landlord for all
         costs thereby incurred within fifteen (15) days after delivery of a
         written demand therefor from Landlord (which shall be accompanied by
         reasonable substantiation of such costs). In the alternative, Landlord
         shall have the right to require Tenant, at its sole cost and expense,
         to perform the necessary remediation in accordance with a detailed plan
         of remediation which shall have been approved in advance in writing by
         Landlord. Landlord shall give notice to Tenant within thirty (30) days
         after Landlord receives notice or obtains knowledge of the required
         remediation. The rights and obligations of Landlord and Tenant set
         forth in this clause (iv) shall survive the expiration or earlier
         termination of this Lease.

                  (v) notwithstanding any other provisions of this Lease, allow
         Landlord, and any authorized representative of Landlord, access and the
         right to enter and inspect the Premises for Environmental Activity, at
         any time deemed reasonable by Landlord, upon prior notice to Tenant on
         the terms set forth in Article 19.

Compliance by Tenant with any provision of this Section 7.5 shall not be deemed
a waiver of any other provision of this Lease. Without limiting the foregoing,
Landlord's consent to any Environmental Activity shall not relieve Tenant of its
indemnity obligations under the terms hereof.

                  Except as set forth in the Phase I Environmental Assessment
dated January 22, 1996 prepared by William Dubovsky Environmental and that
certain letter dated April 12, 1999 prepared by William Dubovsky Environmental,
to Landlord's knowledge, (a) no Hazardous Substance is present on the Building
or the soil, surface water or groundwater of the Land, (b) no underground
storage tanks are present on the Land, and (c) no action proceeding or claim is
pending or threatened regarding the Building concerning any Hazardous Substance
or pursuant to any Environmental Law. Landlord shall promptly remedy and shall
indemnify, defend, protect and hold harmless Tenant, its agents, contractors,
stockholders, directors, successors, representatives, and assigns from and
against, all losses, costs, claims, liabilities and damages (including
attorneys' and consultants' fees) of every type and nature, directly or
indirectly arising out of or in connection with any Hazardous Substance present
at any time on or about the Building, or the soil, air, improvements,
groundwater or surface water of the Land, or the violation of any Environmental
Laws, except to the extent that any of the foregoing results from the
Environmental Activity by Tenant or any of Tenant's subtenants or any of their
respective agents, employees, contractors or invitees, in violation of
Environmental Laws.

                  This Section 7.5 of the Lease constitutes the entire agreement
of Landlord and Tenant regarding Hazardous Substances.

                  7.6. Special Provisions Relating to The Americans With
Disabilities Act of 1990.

                           7.6.1. Allocation of Responsibility to Landlord. As
between Landlord and Tenant, Landlord shall be responsible that the Building as
of the Commencement Date complies with the requirements of Title III of the
Americans with Disabilities Act of 1990 (42 U.S.C. 12181, et seq., The
Provisions Governing Public Accommodations and Services Operated by Private
Entities), and all



                                      -10-

regulations promulgated thereunder, and all amendments, revisions or
modifications thereto now or hereafter adopted or in effect in connection
therewith (hereinafter collectively referred to as the "ADA"), and to take such
actions and make such alterations and improvements as are necessary for such
compliance. All costs incurred by Landlord in discharging its responsibilities
under this Section 7.6.1 shall be included in Operating Expenses to the extent
permitted by Section 1.1.

                           7.6.2. Allocation of Responsibility to Tenant. As
between Landlord and Tenant, Tenant, at its sole cost and expense, shall be
responsible that all Alterations to the Premises (excluding any alterations,
additions or other improvements to the Premises made by or on behalf of Tenant
during the initial improvement of the Premises pursuant to the Work Letter),
Tenant's particular use and occupancy of the Premises, and Tenant's performance
of its obligations under this Lease, comply with the requirements of the ADA,
and to take such actions and make such Alterations as are necessary for such
compliance; provided, however, that Tenant shall not make any such Alterations
except upon Landlord's prior written consent pursuant to the terms and
conditions of this Lease. Tenant shall protect, defend, indemnify and hold
Landlord harmless from and against any claim, demand, cause of action,
obligation, liability, loss, cost or expense (including reasonable attorneys'
fees) which may be asserted against or incurred by Landlord as a result of
Tenant's failure in any respect to comply with its obligations set forth in this
Section 7.6.2. Tenant's indemnity obligations set forth in the immediately
preceding sentence shall survive the expiration or earlier termination of this
Lease.

                           7.6.3. General. Notwithstanding anything in this
Lease to the contrary, no act or omission of Landlord, including any approval,
consent or acceptance by Landlord or Landlord's agents, employees or other
representatives, shall be deemed an agreement, acknowledgment, warranty, or
other representation by Landlord that Tenant has complied with the ADA or that
any action, alteration or improvement by Tenant complies or will comply with the
ADA or constitutes a waiver by Landlord of Tenant's obligations to comply with
the ADA under this Lease or otherwise. Any failure of Landlord to comply with
the obligations of the ADA shall not relieve Tenant from any obligations under
this Lease or constitute or be construed as a constructive or other eviction of
Tenant or disturbance of Tenant's use and possession of the Premises.

         8.  Building Services.

                  8.1. Maintenance of Building. Except as provided in Section 9,
Landlord shall maintain the Building in good order and condition, except for
ordinary wear and tear, damage by casualty or condemnation, or damage occasioned
by the act or omission of Tenant or Tenant's employees, agents, contractors,
licensees or invitees, which damage by Tenant or Tenant's employees, agents,
contractors, licensees or invitees shall be repaired by Landlord at Tenant's
expense. Landlord shall perform and construct, and Tenant shall have no
responsibility to perform or construct, any repair, maintenance or improvements
(a) to the roof or the structural portions of the Building, (b) which could be
treated as a "capital expenditure" under generally accepted accounting
principles, (c) to the heating, ventilating, air conditioning, electrical, fire
and life safety, water, sewer, and plumbing systems serving the Premises and the
Building, (d) to any exterior or other portion of the Land outside of the
demising walls of the Premises, (e) due to negligent acts or omissions of
Landlord or (f) for which Landlord has a right of reimbursement. Notwithstanding
the foregoing, Tenant shall pay for its share of the repairs described above to
the extent such costs are properly included in Operating Expenses. Landlord's
maintenance of, and provision of services to, the Building shall be performed in
a manner consistent with that of comparable office buildings in the San
Francisco, California area. Landlord shall not be in default under this Lease or
liable for any damages directly or indirectly resulting from or incidental to,
nor shall the rental reserved in this Lease be abated by reason of, Landlord's
failure to make any repair or to perform any maintenance required to be made or
performed by Landlord under this Section 8.1, except as otherwise provided in
Section 20.6 or unless such failure shall persist for



                                      -11-
<PAGE>   15

an unreasonable time after written notice of the need for such repair or
maintenance is given to Landlord by Tenant; provided, however, that Landlord
shall be liable only to Tenant for actual, out of pocket, costs or expenses
incurred by Tenant as a direct result of Landlord's failure to cause the floor
lobby or elevators of the Building to comply with laws which are immediately
applicable to, and enforceable against, the Building (subject to Landlord's
reasonable right of contest of such laws).


                  8.2. Building Standard Services. During the Term, the Premises
shall be furnished with water, gas, electricity and heating, ventilating and air
conditioning in the capacity set forth in the Work Letter. Any additional
utility services required by Tenant shall be procured by Tenant at its sole cost
and expense and shall comply with all regulations and limitations as may be
prescribed by any applicable policies, regulations or guidelines adopted by any
federal, state or local governmental or quasi-governmental entities or utility
suppliers. Landlord may establish in the Premises such measures as are required
by laws, ordinances, rules or regulations or as it deems necessary or
appropriate to conserve energy, including automatic switching of lights and/or
more efficient forms of lighting. Tenant shall have access to the Building and
all of the foregoing services 24 hours a day, 7 days a week.

                  8.3. Interruption or Unavailability of Services. Rent shall
not abate, no constructive or other eviction shall be construed to have
occurred, Tenant shall not be relieved from any of its obligations under this
Lease, and Landlord shall not be in default hereunder or liable for any damages
directly or indirectly resulting from, the failure of Landlord to furnish, or
delay in furnishing, any maintenance or services under this Article 8 as a
result of repairs, alterations, improvements or any circumstances beyond
Landlord's reasonable control. Landlord shall use reasonable diligence to remedy
any failure or interruption in the furnishing of such maintenance or services.
Notwithstanding anything set forth in this Lease to the contrary, if such
interruption or interference with access to the Premises, or unavailability of
services continues for more than thirty (30) consecutive days and such
interruption or unavailability prevents Tenant from using the Premises, then
commencing upon the expiration of such thirty (30) day period, Rent shall abate
until beneficial use of the Premises is restored.

                  8.4. Tenant's Payment of Utilities. Commencing on the
Commencement Date and continuing throughout the Term, Tenant shall pay directly
to the utility providing such service, as the same become due, all charges for
water, gas, electricity, steam, telephone, sewer, waste pick-up and any other
utilities, materials or services furnished to the Premises and/or used by Tenant
on or about the Premises during the Term, including, without limitation, (i)
meter, use, connection, hook-up and/or standby fees (including any connection or
hook-up fees which relate to making the existing electrical, steam, gas, and
water service available to the Premises as of or following the Commencement
Date), and (ii) penalties for discontinued or interrupted service relating to
discontinuance and interruptions following the Commencement Date (except
penalties resulting from Landlord's acts or omissions).

         9. Maintenance of Premises. Except as set forth in the second sentence
of Section 8.1, Tenant shall, at all times during the Term, at Tenant's cost and
expense, keep the Premises in good condition and repair, except for ordinary
wear and tear and damage by casualty or condemnation. Tenant shall obtain at its
own cost janitorial supplies and services for the Premises (which services shall
at a minimum consist of vacuuming, emptying waste baskets and dusting at least
five days a week) so that the interior of the Premises shall be maintained in a
clean and sanitary order and condition as required by this Article 9. Except as
may be specifically set forth in this Lease (including the Work Letter),
Landlord has no obligation to alter, remodel, improve, repair, decorate or paint
the Premises, or any part thereof, or any obligation respecting the condition,
maintenance and repair of the Premises or any other portion of the Building.
Except as expressly set forth herein, Tenant hereby waives all rights, including
those provided in California Civil Code Section 1941 or any successor statute,
to make repairs which are Landlord's



                                      -12-
<PAGE>   16

obligation under this Lease at the expense of Landlord or to receive any setoff
or abatement of Rent or in lieu thereof to vacate the Premises or terminate this
Lease.

         10.  Alterations to Premises.

                  10.1. Landlord Consent; Procedure. Tenant shall not make or
permit to be made any Alterations without Landlord's prior consent, which
consent may be granted or withheld in Landlord's reasonable discretion; no
consent shall be required for non-structural Alterations which do not require a
building permit and which, in the aggregate per project, cost less than
$25,000.00 to construct. Any Alterations to which Landlord has consented shall
be made in accordance with procedures as then established by Landlord and the
provisions of this Article 10.

                  10.2. General Requirements. All Alterations shall be made at
Tenant's cost and expense. Tenant shall be solely responsible for compliance
with applicable laws, ordinances, rules and regulations in connection with all
Alterations. Tenant shall be responsible for the cost of any additional
alterations required by applicable laws, ordinances, rules and regulations to be
made by Landlord to any portion of the Building as a result of Alterations.
Tenant shall promptly commence or cause the commencement of construction of all
Alterations and complete or cause completion of the same with due diligence as
soon as possible after commencement.

                  10.3. Removal of Alterations. If required by Landlord at the
time Landlord provides consent to an Alteration, Tenant shall, prior to the
expiration of the Term or termination of this Lease, remove such Alteration at
Tenant's cost and expense and restore the Premises to the condition existing
prior to the installation of such Alteration. If Tenant fails so to do, then
Landlord may remove such Alteration and perform such restoration and Tenant
shall reimburse Landlord for Landlord's cost and expense incurred to perform
such removal and restoration (which obligation of Tenant shall survive the
expiration or earlier termination of this Lease). Tenant shall repair at its
cost and expense all damage to the Premises or the Building caused by the
removal of such Alteration. Subject to the foregoing provisions regarding
removal, all Alterations (including any above Building standard improvements to
the Premises) shall be Landlord's property and from and after the expiration or
earlier termination of this Lease shall remain on the Premises without
compensation to Tenant. Tenant's trade fixtures, furniture, equipment and other
personal property installed in the Premises ("Tenant's Property") shall at all
times be and remain Tenant's property. Tenant may remove Tenant's Property from
the Premises at any time, provided that Tenant repairs all damage caused by such
removal. Landlord shall have no lien or other interest in any item of Tenant's
Property.

         11. Liens. Tenant shall keep the Premises and the Building free from
any liens arising out of any work performed or obligations incurred by or for,
or materials furnished to, Tenant pursuant to this Lease or otherwise. Landlord
shall have the right to post and keep posted on the Premises any notices
required by law or which Landlord may deem to be proper for the protection of
Landlord, the Premises and the Building from such liens and to take any other
action at the expense of Tenant that Landlord deems necessary or appropriate to
prevent, remove or discharge such liens. Tenant shall protect, defend, indemnify
and hold Landlord harmless from and against any claim, demand, cause of action,
obligation, liability, loss, cost or expense (including reasonable attorneys'
fees) which may be asserted against or incurred by Landlord as a result of
Tenant's failure to comply with the foregoing obligation (which indemnity
obligation shall survive the expiration or earlier termination of this Lease).

         12.  Damage or Destruction.

                  12.1. Obligation to Repair. Except as otherwise provided in
this Article 12, if the



                                      -13-
<PAGE>   17

Premises, or any other portion of the Building necessary for Tenant's use and
occupancy of the Premises, are damaged or destroyed by fire or other casualty,
Landlord shall, within thirty (30) days after such event, notify Tenant of the
estimated time, in Landlord's reasonable judgment, required to repair such
damage or destruction. Unless Landlord terminates this Lease as set forth in
Section 12.2, then (i) Landlord shall proceed with all due diligence to repair
the Premises, and/or the portion of the Building necessary for Tenant's use and
occupancy of the Premises, to substantially the condition existing immediately
before such damage or destruction, as permitted by and subject to then
applicable laws, ordinances, rules and regulations; (ii) this Lease shall remain
in full force and effect; and (iii) Rent shall abate for such part of the
Premises rendered unusable by Tenant in the conduct of its business during the
time such part is so unusable, in the proportion that the Rentable Area
contained in the unusable part of the Premises bears to the total Rentable Area
of the Premises.

                  12.2. Termination Rights. If Landlord determines that the
necessary repairs cannot be completed within two hundred seventy (270) days
after the date of damage or destruction, or if such damage or destruction arises
from causes not covered by Landlord's insurance policy required to be carried
hereunder, Landlord may elect, in its notice to Tenant pursuant to Section 12.1,
to (i) terminate this Lease or (ii) repair the Premises pursuant to the
applicable provisions of Section 12.1 above. If Landlord terminates this Lease,
then this Lease shall terminate as of the date of occurrence of the damage or
destruction. If Landlord determines that the necessary repairs cannot be
completed within two hundred seventy (270) days after the date of damage but
Landlord does not elect terminate the Lease pursuant to this Section 12.2,
Tenant shall have the right to terminate the Lease upon written notice to Tenant
to be delivered within ten (10) days of receipt by Tenant of Landlord's notice
of Landlord's determination that such damage or destruction cannot be completed
within two hundred seventy (270) days. Notwithstanding anything to the contrary
herein, Landlord shall not have the right to terminate the Lease if (i) that
portion of the damage or destruction arising from causes covered by Landlord's
insurance policy required to be carried hereunder may be completed within two
hundred seventy (270) days after the date of damage or destruction; (ii) the
cost of that portion of the damage or destruction arising from causes not
covered by Landlord's insurance policy required to be carried hereunder is less
than five percent (5%) of the replacement cost of the Building; or (iii) Tenant
deposits with Landlord prior to the commencement of any restoration work the
full cost of the uninsured portion of the costs required to repair the Building.


                  12.3. Cost of Repairs. Landlord shall pay the cost for repair
of the Building and all improvements in the Premises, other than any
Alterations. If Tenant elects to repair any damaged Alterations, Tenant shall
pay the costs therfor (but Landlord shall make available to Tenant for such
purpose any insurance proceeds received by Landlord for such purpose under
Landlord's insurance policy then in force). Tenant may also replace or repair,
at Tenant's cost and expense, Tenant's movable furniture, equipment, trade
fixtures and other personal property in the Premises which Tenant shall be
responsible for insuring during the Term of this Lease.

                  12.4. Damage at End of Term. Notwithstanding anything to the
contrary contained in this Article 12, if the Premises, or any other portion
thereof or of the Building, are materially damaged or destroyed by fire or other
casualty within the last seven (7) months of the Term, then Landlord shall have
the right, in its sole discretion, to terminate this Lease by notice to Tenant
given within ninety (90) days after the date of such event. Such termination
shall be effective on the date specified in Landlord's notice to Tenant, but in
no event later than the end of such 90-day period. For purposes hereof, the
Premises or other portion of the Building shall be deemed to be materially
damaged if such damage costs more than $2,000,000 to repair

                  12.5. Waiver of Statutes. The respective rights and
obligations of Landlord and Tenant



                                      -14-
<PAGE>   18

in the event of any damage to or destruction of the Premises, or any other
portion of the Building, are governed exclusively by this Lease. Accordingly,
Tenant hereby waives the provisions of any law to the contrary, including
California Civil Code Sections 1932(2) and 1933(4) providing for the termination
of a lease upon destruction of the leased property.

         13.  Eminent Domain.

                  13.1. Effect of Taking. Except as otherwise provided in this
Article 13, if all or any part of the Premises is taken as a result of the
exercise of the power of eminent domain or condemned for any public or
quasi-public purpose, or if any transfer is made in avoidance of such exercise
of the power of eminent domain (collectively, "taken" or a "taking"), this Lease
shall terminate as to the part of the Premises so taken as of the effective date
of such taking. On a taking of a portion of the Premises, Tenant shall have the
right to terminate this Lease by notice to Landlord given within thirty (30)
days after the effective date of such taking, if the portion of the Premises
taken is of such extent and nature so as to materially impair Tenant's business
use of the balance of the Premises, as reasonably determined by Tenant. Such
termination shall be operative as of the effective date of the taking. Landlord
may terminate this Lease on a taking of any material portion of the Building if
Landlord reasonably determines that such taking is of such extent and nature as
to render the operation of the remaining Building economically infeasible or to
require a substantial alteration or reconstruction of such remaining portion.
Landlord shall elect such termination by notice to Tenant given within thirty
(30) days after the effective date of such taking, and such termination shall be
operative as of the effective date of such taking. Upon a taking of the Premises
which does not result in a termination of this Lease, the Base Rent shall
thereafter be reduced as of the effective date of such taking in the proportion
that the rentable area of the Premises so taken bears to the total rentable area
of the Premises.

                  13.2. Condemnation Proceeds. Except as hereinafter provided,
in the event of any taking, Landlord shall have the right to all compensation,
damages, income, rent or awards made with respect thereto (collectively an
"award"), including any award for the value of the leasehold estate created by
this Lease. No award to Landlord shall be apportioned and, subject to Tenant's
rights hereinafter specified, Tenant hereby assigns to Landlord any right of
Tenant in any award made for any taking. Notwithstanding the foregoing, Tenant
may seek to recover, at its cost and expense, as a separate claim, any damages
or awards payable on a taking of the Premises to compensate for the unamortized
cost paid by Tenant for the alterations, additions or improvements, if any, made
by or on behalf of Tenant during the initial improvement of the Premises
pursuant to the Work Letter and for any Alterations, or for Tenant's personal
property taken, or for interference with or interruption of Tenant's business
(including goodwill), or for Tenant's removal and relocation expenses.

                  13.3. Restoration of Premises. On a taking of the Premises
which does not result in a termination of this Lease, Landlord and Tenant shall
restore the Premises as nearly as possible to the condition they were in prior
to the taking in accordance with the applicable provisions and allocation of
responsibility for repair and restoration of the Premises on damage or
destruction pursuant to Article 12 above, and both parties shall use any awards
received by such party attributable to the Premises for such purpose.

                  13.4. Tenant Waiver. The rights and obligations of Landlord
and Tenant on any taking of the Premises or any other portion of the Building
are governed exclusively by this Lease. Accordingly, Tenant hereby waives the
provisions of any law to the contrary, including California Code of Civil
Procedure Sections 1265.120 and 1265.130, or any similar successor statute.

         14.  Insurance.



                                      -15-
<PAGE>   19

                  14.1. Liability Insurance. Landlord, with respect to the
Building, and Tenant, at its cost and expense with respect to the Premises,
shall each maintain or cause to be maintained, from the Lease Date and
throughout the Term, a policy or policies of Commercial General Liability
insurance with limits of liability not less than Two Million Dollars
($2,000,000.00) per occurrence and in the aggregate. Each policy shall contain
coverage for blanket contractual liability, personal injury liability, and
premises operations, coverage deleting liquor liability exclusions and, as to
Tenant's insurance, fire legal liability. Landlord shall have the right to
approve the deductible under each policy of Tenant's liability insurance, such
approval not to be unreasonably withheld.

                  14.2. Form of Policies. All insurance required by this Article
14 shall be issued on an occurrence basis by solvent companies qualified to do
business in the State of California, with a Best's rating of at least A and a
financial size category of at least Class X, as set forth in the most recent
edition of Best's. Any insurance required under this Article 14 may be
maintained under a "blanket policy", insuring other parties and other locations,
so long as the amount and coverage required to be provided hereunder is not
thereby diminished. Tenant shall provide Landlord a copy of each policy of
insurance or a certificate thereof certifying that the policies contain the
provisions required hereunder. Tenant shall deliver such policies or
certificates to Landlord within (30) days after the Lease Date, but in no event
less than ten (10) business days prior to the Commencement Date or such earlier
date as Tenant or Tenant's contractors, agents, licensees, invitees or employees
first enter the Premises and, upon renewal, not less than thirty (30) days prior
to the expiration of such coverage. All evidence of insurance provided to
Landlord shall provide (i) that Landlord, Landlord's managing agent and any
other person requested by Landlord who has an insurable interest, is designated
as an additional insured without limitation as to coverage afforded under such
policy; (ii) for severability of interests or that the acts or omissions of one
of the insureds or additional insureds shall not reduce or affect coverage
available to any other insured or additional insured; (iii) that the insurer
agrees not to cancel or reduce the coverage under the policy without at least
thirty (30) days prior written notice to all additional insureds; (iv) that the
aggregate liability applies solely to the Premises and the remainder of the
Building; and (v) that Tenant's insurance is primary and noncontributing with
any insurance carried by Landlord.

                  14.3.  Workers' Compensation Insurance.  Tenant, at its sole
cost and expense, shall maintain Workers' Compensation insurance as required by
law and employer's liability insurance in an amount of not less than Five
Hundred Thousand Dollars ($500,000).

                  14.4. Additional Tenant Insurance. Tenant, at its sole cost
and expense, shall maintain such other insurance as Landlord may reasonably
require from time to time, but in no event may Landlord require any other
insurance which is (i) not then being required of comparable tenants leasing
comparable amounts of space in comparable buildings in the vicinity of the
Building or (ii) not then available at commercially reasonable rates.

                  14.5. Landlord's Casualty Insurance. Landlord shall, during
the Term of this Lease, procure and maintain in full force and effect, a policy
or policies of "all risk" insurance covering the Building and the permanent
tenant improvements in the Premises (including Alterations of which Landlord has
notice), with standard extended coverage, vandalism, malicious mischief and
sprinkler leakage endorsements. The amount and scope of coverage of Landlord's
insurance hereunder shall be determined by Landlord from time to time in its
reasonable discretion based on prudent risk management practices for buildings
comparable to the Building (but shall not be less than 90% of full replacement
value of the Building and Tenant's permanent tenant improvements in the Premises
(including Alterations of which Landlord has notice), and shall be subject to
such deductible amounts as Landlord may reasonably elect based on prudent risk
management practices for buildings comparable to the Building).



                                      -16-
<PAGE>   20

         15. Waiver of Subrogation Rights. Notwithstanding anything to the
contrary contained in this Lease, Landlord and Tenant, for themselves and their
respective insurers, agree to and do hereby release each other and their
respective employees, contractors, agents, assignees and subtenants, of and from
any and all claims, demands, actions and causes of action that each may have or
claim to have against the other for loss or damage to property, both real and
personal, notwithstanding that any such loss or damage may be due to or result
from the negligence of either of the parties hereto or their respective
employees, contractors, agents, assignees and subtenant, to the extent such
damage is due to a risk that is required to be insured hereunder. Each party
shall, to the extent such insurance endorsement is lawfully available at
commercially reasonable rates, obtain or cause to be obtained, for the benefit
of the other party, a waiver of any right of subrogation which the insurer of
such party may acquire against the other party by virtue of the payment of any
such loss covered by such insurance.

         16.  Tenant's Waiver of Liability and Indemnification.

                  16.1. Waiver and Release. Except to the extent due to the
gross negligence or willful misconduct of Landlord or its agents, employees or
contractors and Landlord's breach of its obligations hereunder, Landlord shall
not be liable to Tenant or Tenant's employees, agents, contractors, licenses or
invitees for, and Tenant waives and releases Landlord and Landlord's managing
agent from, all claims for loss or damage to any property or injury, illness or
death of any person in, upon or about the Premises and/or any other portion of
the Building (including claims caused in whole or in part by the act, omission,
or neglect of other tenants, contractors, licensees, invitees or other occupants
of the Building or their agents or employees). The waiver and release contained
in this Section 16.1 extends to the officers, directors, shareholders, partners,
employees, agents and representatives of Landlord.

                  16.2. Indemnification of Landlord. Tenant shall indemnify,
defend, protect and hold Landlord harmless of and from any and all loss, liens,
liability, claims, causes of action, damage, injury, cost or expense arising out
of or in connection with (i) the making of any alterations, additions or other
improvements made by or Tenant or by its employees, contractors or agents during
the initial improvement of the Premises pursuant to the Work Letter or any
Alterations, or (ii) injury to or death of persons or damage to property
occurring or resulting directly or indirectly from: (A) the use or occupancy of,
or the conduct of business in, the Premises by Tenant or its subtenants or any
of their respective officers, directors, employees, agents, contractors,
invitees or licensees; (B) any other occurrence or condition in or on the
Premises; and (C) the negligence or willful ,misconduct of Tenant , its
subtenants or any of their respective officers, directors, employees, agents,
contractors, invitees or licensees, in or about any portion of the Building.
Tenant's indemnity obligation includes reasonable attorneys' fees and costs,
investigation costs and all other reasonable costs and expenses incurred by
Landlord. If Landlord disapproves the legal counsel proposed by Tenant for the
defense of any claim indemnified against hereunder, Landlord shall have the
right to appoint its own legal counsel, the reasonable fees, costs and expenses
of which shall be included as part of Tenant's indemnity obligation hereunder.
The indemnification contained in this Section 16.2 shall extend to the officers,
directors, shareholders, partners, employees, agents and representatives of
Landlord.

                  16.3. Indemnification of Tenant. Notwithstanding anything to
the contrary herein, Landlord shall not be released or indemnified from and
shall indemnify, defend, protect and hold Tenant harmless of and from any and
all loss, liens, liability, claims, causes of action, damage, injury, cost or
expense arising out of or in connection with (i) any breach or default by
Landlord in the performance of any of its obligations under this Lease, (ii) the
negligence or willful misconduct of Landlord or its agents, employees or
contractors, or (iii) any loss or damage to property or injury to person

<PAGE>   21

Building or the other public areas in the Building (except for such loss, damage
or injury for which Tenant is obligated to indemnify Landlord under Section
16.2).

         17.  Assignment and Subletting.

                  17.1. Compliance Required. Tenant shall not, directly or
indirectly, voluntary or by operation of law, sell, assign or otherwise transfer
this Lease, or any interest herein (collectively, "assign" or "assignment"), or
sublet the Premises, or any part thereof, or permit the occupancy of the
Premises by any person other than Tenant (collectively, "sublease" or
"subletting", the assignee or sublessee under an assignment or sublease being
referred to as a "transferee"), without Landlord's prior consent given or
withheld in accordance with the express standards and conditions of this Article
17 and compliance with the other provisions of this Article 17. Any assignment
or subletting made in violation of this Article 17 shall be void. Tenant
acknowledges and agrees that the limitations on Tenant's right to sublet or
assign which are set forth in this Article 17 are reasonable and, in particular,
that the express standards and conditions upon Tenant's right to assign or
sublet which are set forth in this Article 17 are reasonable as of the Lease
Date.

                  17.2. Request by Tenant; Landlord Response. If Tenant desires
to effect an assignment or sublease, Tenant shall submit to Landlord a request
for consent together with the identity of the parties to the transaction, the
nature of the transferee's proposed business use for the Premises, the proposed
documentation for and terms of the transaction, and all other information
reasonably requested by Landlord concerning the proposed transaction and the
parties involved therein, including certified financial information, credit
reports, the business background and references regarding the transferee, and an
opportunity to meet and interview the transferee. Within fifteen (15) days after
the later of such interview or the receipt of all such information required by
Landlord, or within fifteen (15) days after the date of Tenant's request to
Landlord if Landlord does not request additional information or an interview,
Landlord shall have the right, by notice to Tenant, to: (i) consent to the
assignment or sublease, subject to the terms of this Article 17; or (ii) decline
to consent to the assignment or sublease. Provided that the request for consent
and documentation is marked "LANDLORD'S RESPONSE IS REQUIRED WITHIN 15 DAYS OF
RECEIPT OF THIS NOTICE PURSUANT TO THE TERMS OF THE LEASE BETWEEN LANDLORD AND
THE UNDERSIGNED" and the envelope containing the request is marked "PRIORITY",
Landlord's failure to respond within the fifteen-day period described in the
foregoing sentence shall constitute Landlord's consent to the proposed sublease
or assignment.

                  17.3. Conditions for Landlord Approval. Landlord shall not
unreasonably withhold its consent to a proposed subletting or assignment by
Tenant. Without limiting the grounds on which it may be reasonable for Landlord
to withhold its consent to an assignment or sublease, Tenant agrees that
Landlord would be acting reasonably in withholding its consent in the following
instances: (i) if Tenant is in default under this Lease after applicable notice
and cure periods; (ii) if the transferee is a governmental or quasi-governmental
agency, foreign or domestic; (iii) if, in Landlord's sole but reasonably
judgment, the transferee's business, use and/or occupancy of the Premises would
(A) violate any of the terms of this Lease , or (B) require any Alterations
which would reduce the value of the existing leasehold improvements in the
Premises; (iv) if the financial condition of the transferee does not meet the
requirements that would be applied by Landlord for a tenant in the Building
under leases with comparable terms. If Landlord consents to an assignment or
sublease, the terms of such assignment or sublease transaction shall not be
modified without Landlord's prior written consent pursuant to this Article 17.
Landlord's consent to an assignment or subletting shall not be deemed consent to
any subsequent assignment or subletting.

                  17.4. Costs and Expenses. As a condition to the effectiveness
of any assignment or



                                      -18-
<PAGE>   22

subletting under this Article 17, Tenant shall pay to Landlord all reasonable
costs and expenses, including reasonable attorneys' fees and disbursements,
incurred by Landlord in evaluating Tenant's requests for assignment or sublease,
whether or not Landlord consents to an assignment or sublease. Tenant shall pay
the processing fee with Tenant's request for Landlord's consent under Section
17.2.

                  17.5. Payment of Excess Rent and Other Consideration. Tenant
shall also pay to Landlord, promptly upon Tenant's receipt thereof, fifty
percent (50%) of any and all rent, sums or other consideration, howsoever
denominated, realized by Tenant in connection with any assignment or sublease
transaction in excess of the Base Rent and Escalation Rent payable hereunder
(prorated to reflect the Rent allocable to the portion of the Premises if a
sublease), after first deducting, (i) in the case of an assignment, the
unamortized reasonable cost of Alterations paid for by Tenant and reasonable
attorney's fee and real estate commissions paid by Tenant in connection with
such assignment and, (ii) in the case of a sublease, the reasonable cost of
Alterations made to the Premises at Tenant's cost to effect the sublease, and
the reasonable attorney's fees and the amount of any real estate commissions
paid by Tenant, both amortized over the term of the sublease.

                  17.6. Assumption of Obligations; Further Restrictions on
Subletting. Each assignee shall, concurrently with any assignment, assume all
obligations of Tenant under this Lease. Each sublease shall be made subject to
this Lease and all of the terms, covenants and conditions contained herein; and
the surrender of this Lease by Tenant, or a mutual cancellation thereof, or the
termination of this Lease in accordance with its terms, shall not work a merger
and shall, at the option of Landlord, terminate all or any existing subleases or
operate as an assignment to Landlord of any or all such subleases. No sublessee
of a sublessee shall have the right further to sublet more than one additional
time. Any assignment by a sublessee of its sublease shall be subject to
Landlord's prior consent in the same manner as a sublease by Tenant. No
sublease, once consented to by Landlord, shall be modified without Landlord's
prior consent. No assignment or sublease shall be binding on Landlord unless the
transferee delivers to Landlord a fully executed counterpart of the assignment
or sublease which contains the assumption by the assignee, or recognition by the
sublessee, of the provisions of this Section 17.6, in form and substance
satisfactory to Landlord, but the failure or refusal of a transferee to deliver
such instrument shall not release or discharge such transferee from the
provisions and obligations of this Section 17.6, but such failure shall
constitute a breach under this Lease by Tenant.

                  17.7. No Release. No assignment or sublease shall release
Tenant from its obligations under this Lease, whether arising before or after
the assignment or sublease. The acceptance of Rent by Landlord from any other
person shall not be deemed a waiver by Landlord of any provision of this Article
17. On a default by any assignee of Tenant in the performance of any of the
terms, covenants or conditions of this Lease, Landlord may proceed directly
against Tenant without the necessity of commencing or exhausting remedies
against such assignee. No consent by Landlord to any further assignments or
sublettings of this Lease, or any modification, amendment or termination of this
Lease, or extension, waiver or modification of payment or any other obligations
under this Lease, or any other action by Landlord with respect to any assignee
or sublessee, or the insolvency, or bankruptcy or default of any such assignee
or sublessee, shall affect the continuing liability of Tenant for its
obligations under this Lease and Tenant waives any defense arising out of or
based thereon, including any suretyship defense of exoneration. Landlord shall
have no obligation to notify Tenant or obtain Tenant's consent with respect to
any of the foregoing matters.

                  17.8. No Encumbrance. Notwithstanding anything to the contrary
contained in this Article 17, Tenant shall have no right to encumber, pledge,
hypothecate or otherwise transfer this Lease, or any of Tenant's interest or
rights hereunder, as security for any obligation or liability of Tenant without
Landlord's prior written consent.

                17.9 Assignment or Sublease to Related Entity. As long as
Critical Path or a Related Entity (as defined herein) is the Tenant in
possession of the Premises and no default then exists beyond applicable notice
and cure periods, Tenant shall have the right, subject to the terms and
conditions set forth in this Sections 17.9 but not Section 17.5, without the
consent of Landlord, but without in any way releasing Critical Path from any of
its obligations under this Lease, to (a) assign its interest in this Lease to a
corporation or other entity which shall control, be under the control of, or be
under common control with Critical Path (the term "control" as used herein shall
be deemed to mean ownership of more than fifty percent (50%) of the outstanding
voting stock of a corporation, or other majority equity and control interest if
Tenant is not a corporation) or successor entity related to Tenant by merger,
consolidation or reorganization or a purchaser of substantially all of Tenant's
assets (any such entity being a "Related Entity") or (b) sublease all or any
portion of the Premises to a Related Entity, so long as such sublease does not
result in the demising of any space in the Premises. Any assignment or sublease
to a Related Entity pursuant to this Section 17.9 shall be subject to the
following conditions: (i) the principal purpose of such assignment or sublease
is not the acquisition of Tenant"s interest in this Lease (except if such
assignment or sublease is made to a Related Entity and is made for a valid
intra-corporate business purpose and is not made to circumvent the provisions of
this Article 17), (ii) any such assignee shall have a net worth and annual
income and cash flow, determined in accordance with generally accepted
accounting principles, consistently applied, after giving effect to such
assignment, in amounts necessary to perform its duties, obligations and
liabilities hereunder, as reasonably determined by Landlord, (iii) such
assignment or sublease shall be subject to the terms of this Lease, including
the provisions of Sections 17.6 and 17.7, and (iv) such Related Entity shall
have executed all documents reasonably requested by Landlord to memorialize the
foregoing. Tenant shall, within ten (10) business days after execution thereof,
deliver to Landlord (A) a duplicate original instrument of assignment in form
and substance reasonably satisfactory to Landlord, duly executed by Tenant, (B)
if applicable, evidence reasonably satisfactory to Landlord establishing
compliance by the assignee with the net worth, income and cash flow requirements
of clause (b)(ii) above, (C) an instrument in form and substance reasonably
satisfactory to Landlord, duly executed by the assignee, in which such assignee
shall assume observance and performance of, and agree to be personally bound by,
all of the terms, covenants and conditions of this Lease on Tenant"s part to be
observed and performed or (D) a duplicate original sublease in form and
substance reasonably satisfactory to Landlord, duly executed by Tenant and
subtenant.

        18. Rules and Regulations. Tenant shall observe and comply, and shall
cause its sublessees, employees, agents, contractors, licensees and invitees to
observe and comply, with the Rules and Regulations of the Building, a copy of
which are attached to this Lease as Exhibit D, and, after notice thereof, with
all modifications and additions thereto from time to time promulgated in writing
by Landlord. Landlord shall not be responsible to Tenant, or Tenant's
sublessees, employees, agents, contractors, licensees or invitees, for
noncompliance with any Rules and Regulations of the Building by any other
tenant, sublessee, employee, agent, contractor, licensee, invitee or other
occupant of the Building. Tenant shall not be required to comply with any new
rule or regulation unless the same applies non-discriminatorily to all occupants
of the Building, does not unreasonably interfere with Tenant's use of the
Premises or Tenant's parking rights and does not materially increase the
obligations or decrease the rights of Tenant under the Lease

        19. Entry of Premises by Landlord.

                19.1. Right to Enter. Upon 24 hours advance notice to Tenant
(except in emergencies or in order to provide regularly scheduled or other
routine Building standard services or additional services requested by Tenant,
or post notices of nonresponsibility or other notices permitted or required by
law when no such notice shall be required), Landlord and its authorized agents,
employees, and contractors


                                      -20-
<PAGE>   24

enter the Premises at reasonable hours to: (i) inspect the same; (ii) determine
Tenant's compliance with its obligations hereunder; (iii) exhibit the same to
prospective purchasers, lenders or tenants; (iv) supply any services to be
provided by Landlord hereunder; (v) post notices of nonresponsibility or other
notices permitted or required by law; (vi) make repairs, improvements or
alterations, or perform maintenance in or to, the Premises or any other portion
of the Building, including Building systems; and (vii) perform such other
functions as Landlord deems reasonably necessary or desirable. Landlord may also
grant access to the Premises to government or utility representatives and bring
and use on or about the Premises such equipment as reasonably necessary to
accomplish the purposes of Landlord's entry. Landlord shall use reasonable good
faith efforts to effect all entries and perform all work hereunder in such
manner as to minimize interference with Tenant's use and occupancy of the
Premises. Landlord shall have and retain keys with which to unlock all of the
doors in or to the Premises (excluding Tenant's vaults, safes and similar secure
areas designated in writing by Tenant in advance), and Landlord shall have the
right to use any and all means which Landlord may deem proper in an emergency in
order to obtain entry to the Premises, including secure areas. Any entry shall
comply with Tenant's reasonable security measures.

                19.2. Tenant Waiver of Claims. Except for damages to persons or
property caused by the gross negligence or willful misconduct of Landlord,
Tenant waives any claim for damages for any inconvenience to or interference
with Tenant's business, or any loss of occupancy or quiet enjoyment of the
Premises, or any other loss, occasioned by any entry effected or work performed
under this Article 19, and Tenant shall not be entitled to any abatement of Rent
by reason of the exercise of any such right of entry or performance of such
work. No entry to the Premises by Landlord or anyone acting under Landlord shall
constitute a forcible or unlawful entry into, or a detainer of, the Premises or
an eviction, actual or constructive, of Tenant from the Premises, or any portion
thereof.

        20. Default and Remedies.

                20.1. Events of Default. The occurrence of any of the following
events shall constitute a default by Tenant under this Lease:

                        a. Nonpayment of Rent. Failure to pay any Rent when due.

                        b. Unpermitted Assignment. An assignment or sublease
made in contravention of any of the provisions of Article 17 above.

                        c. Abandonment. Abandonment of the Premises for a
continuous period in excess of five (5) business days. For purposes hereof,
"abandonment" shall have the meaning provided under California law.

                        d. Other Obligations. Failure to perform or fulfill any
other obligation, covenant, condition or agreement under this Lease.

                        e. Bankruptcy and Insolvency. A general assignment by
Tenant for the benefit of creditors, any action or proceeding commenced by
Tenant under any insolvency or bankruptcy act or under any other statute or
regulation for protection from creditors, or any such action commenced against
Tenant and not discharged within thirty (30) days after the date of
commencement; the employment or appointment of a receiver or trustee to take
possession of all or substantially all of Tenant's assets or the Premises which
is not discharged within thirty (30) days; the attachment, execution or other
judicial seizure of all or substantially all of Tenant's assets or the Premises,
if such attachment or other seizure remains undismissed or undischarged for a
period of thirty (30) days after the levy thereof; the admission


                                      -21-
<PAGE>   25

by Tenant in writing of its inability to pay its debts as they become due; or
the filing by Tenant of a petition seeking any reorganization, arrangement,
composition, readjustment, liquidation, dissolution or similar relief under any
present or future statute, law or regulation, the filing by Tenant of an answer
admitting or failing timely to contest a material allegation of a petition filed
against Tenant in any such proceeding or, if within thirty (30) days after the
commencement of any such proceeding against Tenant, such proceeding is not
dismissed. For purposes of this Section 20.1(e), "Tenant" means Tenant and any
partner of Tenant, if Tenant is a partnership, or any person or entity
comprising Tenant, if Tenant is comprised of more than one person or entity, or
any guarantor of Tenant's obligations, or any of them, under this Lease.

                        f. 33 Clementina If, at any time that Landlord is also
the owner of the premises leased by Tenant under that certain Office Lease of
even date herewith for premises commonly known as 33 Clementina, San Francisco
(the "Clementina Lease"), Tenant is in default under the Clementina Lease,
beyond any applicable notice and cure period.

                20.2. Notice to Tenant. Upon the occurrence of any default,
Landlord shall give Tenant notice thereof. If a time period is specified below
for cure of such default, then Tenant may cure such default within such time
period.

                        a. Nonpayment of Rent. For failure to pay Rent, within
five (5) days after Landlord's notice, unless Tenant has failed more than two
(2) times during any calendar year to timely pay any Rent, in which event no
cure period shall apply.

                        b. Other Obligations. For failure to perform any
obligation, covenant, condition or agreement under this Lease (other than
nonpayment of Rent or Tenant's abandonment of the Premises) within ten (10) days
after Landlord's notice or, if the failure is of a nature requiring more than 10
days to cure, then an additional forty five (45) days after the expiration of
such 10-day period, but only if Tenant commences cure within such 10-day period
and thereafter diligently pursues such cure to completion within such additional
45-day period. If Tenant has failed to perform any such obligation, covenant,
condition or agreement more than two (2) times during any calendar year and
notice of such event of default has been given by Landlord in each instance,
then no cure period shall apply.

                        c. Assignment/Sublease. For an assignment or subletting
in violation of Article 17, within ten (10) days after Landlord's notice.

                        d. No Cure Period. No cure period shall apply for any
other event of default specified in Section 20.1.

                20.3. Remedies Upon Occurrence of Default. On the occurrence of
a default which Tenant fails to cure after notice and expiration of the time
period for cure, if any, specified in Section 20.2 above, Landlord shall have
the right either (i) to terminate this Lease and recover possession of the
Premises, or (ii) to continue this Lease in effect and enforce all Landlord's
rights and remedies under California Civil Code Section 1951.4 (by which
Landlord may recover Rent as it becomes due, subject to Tenant's right to assign
pursuant to Article 17). Landlord may store any property of Tenant located in
the Premises at Tenant's expense or otherwise dispose of such property in the
manner provided by law. If Landlord does not terminate this Lease, Tenant shall
in addition to continuing to pay all Rent when due, also pay Landlord's costs of
attempting to relet the Premises, any repairs and alterations necessary to
prepare the Premises for such reletting, and brokerage commissions and
attorneys' fees incurred in connection therewith, less the rents, if any,
actually received from such reletting. Notwithstanding Landlord's election to
continue this Lease in effect, Landlord may at any time thereafter


                                      -22-
<PAGE>   26

terminate this Lease pursuant to this Section 20.3.

                20.4. Damages Upon Termination. If and when Landlord terminates
this Lease pursuant to Section 20.3, Landlord may exercise all its rights and
remedies available under California Civil Code Section 1951.2, including the
right to recover from Tenant the worth at the time of award of the amount by
which the unpaid Rent for the balance of the Term after the time of award
exceeds the amount of such Rent loss that the Tenant proves could have been
reasonably avoided. As used herein and in Civil Code Section 1951.2, "time of
award" means either the date upon which Tenant pays to Landlord the amount
recoverable by Landlord, or the date of entry of any determination, order or
judgment of any court or other legally constituted body determining the amount
recoverable, whichever occurs first.

                20.5. Computation of Certain Rent for Purposes of Default. For
purposes of computing unpaid Rent pursuant to Section 20.4 above, Escalation
Rent for the balance of the Term shall be determined by averaging the amount
paid by Tenant as Escalation Rent for the calendar year prior to the year in
which the default occurred (or, if the prior year is the Base Year or such
default occurs during the Base Year, Escalation Rent shall be based on
Landlord's operating budget for the Building for the Base Year), increasing such
average amount for each calendar year (or portion thereof) remaining in the
balance of the Term at a per annum compounded rate equal to the mean average
rate of increase for the preceding five (5) calendar years in the United States
Department of Labor, Bureau of Labor Statistics, Consumer Price Index (All Urban
Consumers, All Items, 1982-1984 = 100) for the Metropolitan Area of which San
Francisco, California, is a part, and adding together the resulting amounts. If
such Index is discontinued or revised, such computation shall be made by
reference to the index designated as the successor or substitute index by the
United States Department of Labor, Bureau of Labor Statistics, or its successor
agency, and if none is designated, by a comparable index as determined by
Landlord in its sole discretion, which would likely achieve a comparable result
to that achieved by the use of the Consumer Price Index. If the base year of the
Consumer Price Index is changed, then the conversion factor specified by the
Bureau, or successor agency, shall be utilized to determine the Consumer Price
Index.

                20.6. Right to Cure Defaults. If Tenant fails to pay Rent (other
than Base Rent and Escalation Rent) required to be paid by it hereunder, or
fails to perform any other obligation under this Lease, and Tenant fails to cure
such default within the applicable cure period, if any, specified in Section
20.2 above, then Landlord may, without waiving any of Landlord's rights in
connection therewith or releasing Tenant from any of its obligations or such
default, make any such payment or perform such other obligation on behalf of
Tenant. All payments so made by Landlord, and all costs and expenses incurred by
Landlord to perform such obligations, shall be due and payable by Tenant as Rent
immediately upon receipt of Landlord's demand therefor. If Landlord fails to
make repairs to the Premises or perform any other obligations under this Lease
which Landlord is required to make pursuant to the terms of this Lease within
fifteen (15) days after written notice from Tenant (provided Landlord shall have
a longer time if reasonably necessary if Landlord commences cure within such
fifteen (15) day period and diligently prosecutes such cure to completion) and
such failure to repair materially and adversely affect Tenant's use of the
Premises, then Tenant shall give Landlord an additional three (3) business days
prior notice. If Landlord has not commenced repair within such three (3)
business day period, Tenant shall have the right to repair the Premises, and
Landlord shall reimburse Tenant for the reasonable cost thereof within thirty
(30) days after presentation of a reasonably detailed invoice demonstrating the
expenses incurred by Tenant. In the event Tenant makes such repairs, Tenant
shall be responsible for damages or injuries caused by Tenant or its employees,
contractors and subcontractors in making such repairs or any defect therein and
shall indemnify Landlord against any liability, cost or expense (including
attorneys' fees) arising out of such repair or any defect in the work performed.
If


                                      -23-
<PAGE>   27

Landlord does not dispute Tenant's right to reimbursement and fails to reimburse
Tenant within such thirty (30) day period, Tenant may deduct the cost of such
cure from Rent.

                20.7. Remedies Cumulative. The rights and remedies of Landlord
under this Lease are cumulative and in addition to, and not in lieu of, any
other rights and remedies available to Landlord at law or in equity. Landlord's
pursuit of any such right or remedy shall not constitute a waiver or election of
remedies with respect to any other right or remedy.

        21. Subordination, Attornment and Nondisturbance.

                21.1. Subordination and Attornment. This Lease and all of
Tenant's rights hereunder shall be subordinate to any ground lease or underlying
lease, and the lien of any mortgage, deed of trust, or any other security
instrument now or hereafter affecting or encumbering the Building, or any part
thereof or interest therein, and to any and all advances made on the security
thereof or Landlord's interest therein, and to all renewals, modifications,
consolidations, replacements and extensions thereof (an "encumbrance", the
holder of the beneficial interest thereunder being referred to as an
"encumbrancer"). An encumbrancer may, however, subordinate its encumbrance to
this Lease, and if an encumbrancer so elects by notice to Tenant, this Lease
shall be deemed prior to such encumbrance. If any encumbrance to which this
Lease is subordinate is foreclosed, or a deed in lieu of foreclosure is given to
the encumbrancer thereunder, Tenant shall attorn to the purchaser at the
foreclosure sale or to the grantee under the deed in lieu of foreclosure; and if
any encumbrance consisting of a ground lease or underlying lease to which this
Lease is subordinate is terminated, Tenant shall attorn to the lessor thereof.
Tenant shall execute, acknowledge and deliver in the form reasonably requested
by Landlord or any encumbrancer, any documents required to evidence or
effectuate the subordination hereunder, or to make this Lease prior to the lien
of any encumbrance, or to evidence such attornment.

                21.2. Nondisturbance. If any encumbrance to which this Lease is
subordinate is foreclosed, or a deed in lieu of foreclosure is given to the
encumbrancer thereunder, or if any encumbrance consisting of a ground lease or
underlying lease to which this Lease is subordinate is terminated, this Lease
shall not terminate, and the rights and possession of Tenant under this Lease
shall not be disturbed if (i) no default by Tenant then exists under this Lease
(after expiration of applicable notice and cure periods); (ii) Tenant attorns to
the purchaser, grantee, or successor lessor as provided in Section 21.1 above
or, if requested, enters into a new lease for the balance of the Term upon the
same terms and provisions contained in this Lease; and (iii) Tenant enters into
a written agreement in a form reasonably acceptable to such encumbrancer with
respect to subordination, attornment and non-disturbance. Concurrent with the
execution of this Lease, Landlord shall use reasonable efforts to obtain a
non-disturbance agreement from the existing encumbrancer in a form reasonably
acceptable to Tenant. If Tenant and the existing encumbrancer are not able to
agree upon a mutually acceptable non-disturbance agreement within fifteen (15)
days after the Lease Date, Tenant shall have the right to terminate the Lease
within three business days after such fifteenth day.

        22. Sale or Transfer by Landlord; Lease Non-Recourse.

                22.1. Release of Landlord on Transfer. Landlord may at any time
transfer, in whole or in part, its right, title and interest under this Lease
and in the Building, or any portion thereof. If the original Landlord hereunder,
or any successor to such original Landlord, transfers (by sale, assignment or
otherwise) its right, title or interest in the Building and the transferee
assumes in writing all of landlord's obligations hereunder, all liabilities and
obligations of the original Landlord or such successor under this Lease accruing
after such transfer shall terminate, the original Landlord or such successor
shall automatically be released therefrom, and thereupon all such liabilities
and obligations shall be binding upon the new owner. Tenant shall attorn to each
such new owner.


                                      -24-
<PAGE>   28

                22.2. Lease Nonrecourse to Landlord. Landlord shall in no event
be personally liable under this Lease, and Tenant shall look solely to
Landlord's interest in the Building (including insurance and condemnation
proceeds, the Security Deposit and all proceeds thereof) of for recovery of any
damages for breach of this Lease by Landlord or on any judgment in connection
therewith. None of the persons or entities comprising or representing Landlord
(whether partners, shareholders, officers, directors, trustees, employees,
beneficiaries, agents or otherwise) shall ever be personally liable under this
Lease or liable for any such damages or judgment and Tenant shall have no right
to effect any levy of execution against any assets of such persons or entities
on account of any such liability or judgment. Any lien obtained by Tenant to
enforce any such judgment, and any levy of execution thereon, shall be subject
and subordinate to all encumbrances as specified in Article 21 above.

        23. Estoppel Certificate.

                23.1. Procedure and Content. From time to time, and within ten
(10) days after written notice by Landlord, Tenant shall execute, acknowledge,
and deliver to Landlord a certificate as specified by Landlord certifying: (i)
that this Lease is unmodified and in full force and effect (or, if there have
been modifications, that this Lease is in full force and effect, as modified,
and identifying each modification); (ii) the Commencement Date and Expiration
Date; (iii) that Tenant has accepted the Premises (or the reasons Tenant has not
accepted the Premises), and if Landlord has agreed to make any alterations or
improvements to the Premises, that Landlord has properly completed such
alterations or improvements (or the reasons why Landlord has not done so); (iv)
the amount of the Base Rent and current Escalation Rent, if any, and the date to
which such Rent has been paid; (v) that Tenant has not committed any event of
default, except as to any events of default specified in the certificate, and
whether there are any existing defenses against the enforcement of Tenant's
obligations under this Lease; (vi) that no default of Landlord is claimed by
Tenant, except as to any defaults specified in the certificate; and (vii) such
other matters as may be requested by Landlord.

                23.2. Effect of Certificate. Any such certificate may be relied
upon by any prospective purchaser of any part or interest in the Building or
encumbrancer (as defined in Section 21.1) and, at Landlord's request, Tenant
shall deliver such certificate to Landlord and/or to any such entity and shall
agree to such notice and cure provisions and such other matters as such entity
may reasonably require. In addition, at Landlord's request, Tenant shall provide
to Landlord for delivery to any such entity such information, including
financial information, that may reasonably be requested by any such entity. Any
such certificate shall constitute a waiver by Tenant of any claims Tenant may
have in contravention to the information contained in such certificate and
Tenant shall be estopped from asserting any such claim. If Tenant fails or
refuses to give a certificate hereunder within the time period herein specified,
then the information contained in such certificate as submitted by Landlord
shall be deemed correct for all purposes, but Landlord shall have the right to
treat such failure or refusal as a default by Tenant.

                23.2. Landlord's Estoppel If Tenant is required by an
unaffiliated third party to produce an estoppel certificate, Landlord shall,
within thirty (30) days after Tenant's request, execute and deliver to Tenant an
estoppel certificate in favor of Tenant and such other persons as Tenant shall
reasonably request, setting forth the following: (a) the Commencement Date and
the Expiration Date; (b) that this Lease is in full force and effect and has not
been assigned, modified, supplemented or amended (except by such writing as
shall be stated); (c) that all conditions under this Lease to be performed by
Tenant have, to Landlord's knowledge, been satisfied, or, in the alternative,
those claimed by Landlord to be unsatisfied; (d) that, to Landlord's knowledge,
no defenses or offsets exist against the enforcement of this Lease by Landlord,
or in the alternative, those claimed by Landlord; (e) that the amount of advance
Rent, if any (or none if such is the case), has been paid by Tenant; (f) the
date to which rent has been paid; and


                                      -25-
<PAGE>   29

(g) such other information as Tenant may reasonably request.

        24. No Light, Air, or View Easement. Nothing contained in this Lease
shall be deemed, either expressly or by implication, to create any easement for
light and air or access to any view. Any diminution or shutting off of light,
air or view to or from the Premises by any structure which now exists or which
may hereafter be erected, whether by Landlord or any other person, shall in no
way affect this Lease or Tenant's obligations hereunder, entitle Tenant to any
reduction of Rent, or impose any liability on Landlord.

        25. Holding Over. No holding over by Tenant shall operate to extend the
Term. If Tenant remains in possession of the Premises after expiration or
termination of this Lease, unless otherwise agreed by Landlord in writing, then
(i) Tenant shall become a tenant at sufferance upon all the applicable terms and
conditions of this Lease, except that Base Rent shall be increased to equal 150%
of the Base Rent then in effect; (ii) Tenant shall indemnify, defend, protect
and hold harmless Landlord, and any tenant to whom Landlord has leased all or
part of the Premises, from any and all liability, loss, damages, costs or
expense (including loss of Rent to Landlord or additional rent payable by such
tenant and reasonable attorneys' fees) suffered or incurred by either Landlord
or such tenant resulting from Tenant's failure timely to vacate the Premises;
and (iii) such holding over by Tenant shall constitute a default by Tenant.

        26. Security Deposit. If so specified in the Basic Lease Information,
Tenant shall deposit with Landlord the Security Deposit upon the execution of
this Lease by Tenant. The Security Deposit shall be held by Landlord as security
for the performance by Tenant of all its obligations under this Lease. If Tenant
fails to pay any Rent due hereunder, or otherwise commits a default (after
applicable notice and cure periods) with respect to any provision of this Lease,
Landlord may use, apply or retain all or any portion of the Security Deposit for
the payment of any such Rent or for the payment of any other amounts expended or
incurred by Landlord by reason of Tenant's default, or to compensate Landlord
for any loss or damage which Landlord may incur thereby (subject to the
provisions of California Civil Code Section 1950.7(c) and any similar or
successor statute providing that Landlord may claim from a security deposit only
those sums reasonably necessary to remedy defaults in the payment of Rent, to
repair damage caused by Tenant, or to clean the Premises). Exercise by Landlord
of its rights hereunder shall not constitute a waiver of, or relieve Tenant from
any liability for, any default. If Landlord so uses or applies all or any
portion of the Security Deposit, Tenant shall, within ten (10) days after demand
by Landlord, deposit cash with Landlord in an amount sufficient to restore the
Security Deposit to its full amount. If Tenant performs all of Tenant's
obligations hereunder, the Security Deposit, or so much thereof as has not
theretofore been applied by Landlord, shall be returned, without interest, to
Tenant (or, at Landlord's option, to the last assignee, if any, of Tenant's
interest under this Lease) within thirty (30) days after the later of (i) the
date of expiration or earlier termination of this Lease, or (ii) vacation of the
Premises by Tenant if the Premises has been left in the condition specified by
this Lease. Landlord's receipt and retention of the Security Deposit shall not
create any trust or fiduciary relationship between Landlord and Tenant and
Landlord need not keep the Security Deposit separate from its general accounts.
Subject to Section 22.1, upon termination of the original Landlord's (or any
successor owner's) interest in the Premises, the original Landlord (or such
successor) shall be released from further liability with respect to the Security
Deposit upon the original Landlord's (or such successor's) compliance with
California Civil Code Section 1950.7(d), or successor statute.

        27. Waiver. Failure of Landlord to declare a default by Tenant upon
occurrence thereof, or delay in taking any action in connection therewith, shall
not waive such default, but Landlord shall have the right to declare such
default at any time after its occurrence. To be effective, a waiver of any


                                      -26-
<PAGE>   30

provision of this Lease, or any default, shall be in writing and signed by the
waiving party. Any waiver hereunder shall not be deemed a waiver of subsequent
performance of any such provision or subsequent defaults. The subsequent
acceptance of Rent hereunder, or endorsement of any check by Landlord, shall not
be deemed to constitute an accord and satisfaction or a waiver of any preceding
default by Tenant, except as to the particular Rent so accepted, regardless of
Landlord's knowledge of the preceding default at the time of acceptance of the
Rent. No course of conduct between Landlord and Tenant, and no acceptance of the
keys to or possession of the Premises by Landlord before the Expiration Date
shall constitute a waiver of any provision of this Lease or of any default, or
operate as a surrender of this Lease.

        28. Notices and Consents; Tenant's Agent for Service. All notices,
approvals, consents, demands and other communications from one party to the
other given pursuant to this Lease shall be in writing and shall be made by
personal delivery, by use of a reputable overnight courier service or by deposit
in the United States mail, certified, registered or Express, postage prepaid and
return receipt requested. Notices shall be addressed if to Landlord, to
Landlord's Address, and if to Tenant, to Tenant's Address. Landlord and Tenant
may each change their respective Addresses from time to time by giving written
notice to the other of such change in accordance with the terms of this Article
28, at least ten (10) days before such change is to be effected. Any notice
given in accordance with this Article 28 shall be deemed to have been given (i)
on the date of personal delivery or (ii) on the earlier of the date of delivery
or attempted delivery (as shown by the return receipt or other delivery record)
if sent by courier service or mailed.

        29. Authority. Tenant represents and warrants that (i) Tenant is a duly
formed, authorized and existing corporation, (ii) Tenant is qualified to do
business in California, (iii) Tenant has the full right and authority to enter
into this Lease and to perform all of Tenant's obligations hereunder, and (iv)
each person signing on behalf of Tenant is authorized to do so. Tenant shall
deliver to Landlord, upon Landlord's request, such certificates, resolutions, or
other written assurances authorizing Tenant's execution and delivery of this
Lease, and such financial information regarding Tenant and its constituent
members, as requested by Landlord from time to time or at any time in order for
Landlord to assess Tenant's then authority and/or ability to meet its
obligations under this Lease. Landlord represents and warrants that (i) Landlord
is a duly formed, authorized and existing limited liability company (ii)
Landlord is qualified to do business in California, (iii) Landlord has the full
right and authority to enter into this Lease and to perform all of Landlord's
obligations hereunder, and (iv) each person signing on behalf of Landlord is
authorized to do so. Landlord shall deliver to Tenant, upon Landlord's request,
such certificates, resolutions, or other written assurances authorizing
Landlord's execution and delivery of this Lease.

        30. Automobile Parking. In consideration for the Base Rent paid
hereunder, Tenant shall have the right to occupy all of the parking stalls in
the Building during the Initial Term and any Extended Term at no additional
cost.

        31. Tenant to Furnish Financial Statements. In order to induce Landlord
to enter into this Lease, Tenant agrees that it shall promptly deliver to
Landlord, from time to time, upon Landlord's written request, publicly available
financial statements (including a balance sheet and statement of income and
expenses on an annualized basis) reflecting Tenant's then current financial
condition. Such statements shall be delivered to Landlord within fifteen (15)
days after Tenant's receipt of Landlord's request. Tenant represents and
warrants that all financial statements, records, and information furnished by
Tenant to Landlord in connection with this Lease are and shall be true, correct
and complete in all respects.

        32. Tenant's Signs. Subject to the following sentence, Tenant shall have
the right to exclusive building signage (including the exclusive right to
utilize any billboard signage from and after January 1,


                                      -27-
<PAGE>   31

2001), but Tenant shall not place on the Premises or on the Building any
exterior signs nor any interior signs that are visible from the exterior of the
Premises or Building without Landlord's prior consent, which Landlord may
withhold in its reasonable discretion. Tenant's right to exclusive building
signage is subject to Landlord's right to maintain the billboard signage located
on the Building until December 31, 2000 Landlord hereby consents to the signage
for the Building substantially similar to that on Tenant's existing building
located at 320 First Street in San Francisco. Tenant shall pay all costs and
expenses relating to any such sign approved by Landlord, including without
limitation, the cost of the installation and maintenance of the sign. On the
date of expiration or earlier termination of this Lease, Tenant, at its sole
cost and expense, shall remove all signs and repair any damage caused by such
removal. If Tenant elects to no longer utilize the billboard signage, Base Rent
payable to Landlord shall be reduced by $6,000 per month for the Initial Term
and any Extended Terms. Tenant shall have the right to terminate the rental of
the billboard signage upon one hundred eighty (180) days' written notice to
Landlord. If Tenant elects to terminate the rental of the billboard signage,
Landlord may rent the billboard signage to a third party, subject to the
reasonable approval of the Tenant. In no case shall Landlord lease any signage
on the Building to a competitor of Tenant.

        33. Miscellaneous.

                33.1. No Joint Venture. This Lease does not create any
partnership or joint venture or similar relationship between Landlord and
Tenant.

                33.2. Successors and Assigns. Subject to the provisions of
Article 17 regarding assignment, all of the provisions, terms, covenants and
conditions contained in this Lease shall bind, and inure to the benefit of, the
parties and their respective successors and assigns.

                33.3. Construction and Interpretation. The words "Landlord" and
"Tenant" include the plural as well as the singular. If there is more than one
person comprising Tenant, the obligations under this Lease imposed on Tenant are
joint and several. References to a party or parties refers to Landlord or
Tenant, or both, as the context may require. The captions preceding the
Articles, Sections and subsections of this Lease are inserted solely for
convenience of reference and shall have no effect upon, and shall be disregarded
in connection with, the construction and interpretation of this Lease. Use in
this Lease of the words "including", "such as", or words of similar import when
following a general matter, shall not be construed to limit such matter to the
enumerated items or matters whether or not language of nonlimitation (such as
"without limitation") is used with reference thereto. All provisions of this
Lease have been negotiated at arm's length between the parties and after advice
by counsel and other representatives chosen by each party and the parties are
fully informed with respect thereto. Therefore, this Lease shall not be
construed for or against either party by reason of the authorship or alleged
authorship of any provision hereof, or by reason of the status of the parties as
Landlord or Tenant, and the provisions of this Lease and the Exhibits hereto
shall be construed as a whole according to their common meaning in order to
effectuate the intent of the parties under the terms of this Lease.

                33.4. Severability. If any provision of this Lease, or the
application thereof to any person or circumstance, is determined to be illegal,
invalid or unenforceable, the remainder of this Lease, or its application to
persons or circumstances other than those as to which it is illegal, invalid or
unenforceable, shall not be affected thereby and shall remain in full force and
effect, unless enforcement of this Lease as so invalidated would be unreasonable
or grossly inequitable under the circumstances, or would frustrate the purposes
of this Lease.

                33.5. Entire Agreement; Amendments. This Lease, together with
the Exhibits hereto and any Addenda identified on the Basic Lease Information,
contains all the representations and the entire


                                      -28-
<PAGE>   32

agreement between the parties with respect to the subject matter hereof and any
prior negotiations, correspondence, memoranda, agreements, representations or
warranties are replaced in total by this Lease, the Exhibits hereto and such
Addenda. Neither Landlord nor Landlord's agents have made any warranties or
representations with respect to the Premises or any other portion of the
Building, except as expressly set forth in this Lease. This Lease may be
modified or amended only by an agreement in writing signed by both parties.

                33.6. Governing Law. This Lease shall be governed by and
construed pursuant to the laws of the State of California.

                33.7. Litigation Expenses. If either party brings any action or
proceeding against the other (including any cross-complaint, counterclaim or
third party claim) to enforce or interpret this Lease or otherwise arising out
of this Lease, the prevailing party in such action or proceeding shall be
entitled to its costs and expenses of suit, including reasonable attorneys' fees
and accountants' fees.

                33.8. Standards of Performance and Approvals. Unless otherwise
provided in this Lease, (i) each party shall act in a reasonable manner in
exercising or undertaking its rights, duties and obligations under this Lease
and (ii) whenever approval, consent or satisfaction (collectively, an
"approval") is required of a party pursuant to this Lease or an Exhibit hereto,
such approval shall not be unreasonably withheld or delayed. Unless provision is
made for a specific time period, approval (or disapproval) shall be given within
thirty (30) days after receipt of the request for approval. Nothing contained in
this Lease shall, however, limit the right of a party to act or exercise its
business judgment in a subjective manner with respect to any matter as to which
it has been (A) specifically granted such right, (B) granted the right to act in
its sole discretion or sole judgment, or (C) granted the right to make a
subjective judgment hereunder, whether "objectively" reasonable under the
circumstances and any such exercise shall not be deemed inconsistent with any
covenant of good faith and fair dealing implied by law to be part of this Lease.
The parties have set forth in this Lease their entire understanding with respect
to the terms, covenants, conditions and standards pursuant to which their
obligations are to be judged and their performance measured, including the
provisions of Article 17 with respect to assignments and sublettings.

                33.9. Brokers. Landlord shall pay to Landlord's Broker and
Tenant's Broker, if any as specified in the Basic Lease Information of this
Lease, a commission in connection with such Brokers' negotiation of this Lease
pursuant to a separate agreement or agreements between Landlord and such
Brokers. Other than such Brokers, Landlord and Tenant each represent and warrant
to the other that no broker, agent, or finder has procured or was involved in
the negotiation of this Lease and no such broker, agent or finder is or may be
entitled to a commission or compensation in connection with this Lease. Landlord
and Tenant shall each indemnify, defend, protect and hold the other harmless
from and against any and all liability, loss, damages, claims, costs and
expenses (including reasonable attorneys' fees) resulting from claims that may
be asserted against the indemnified party in breach of the foregoing warranty
and representation.

                33.10. Memorandum of Lease. Either party shall, upon request of
the other, execute, acknowledge and deliver a short form memorandum of this
Lease (and any amendment hereto) in form suitable for recording. Tenant shall
have the right to record the memorandum and, if Tenant elects to do so, Tenant
shall pay all recording fees and transfer taxes in connection therewith. Upon
termination or expiration of the Lease, Tenant shall promptly execute and record
a quit claim deed or other instrument required to remove such memorandum from
the records of the San Francisco County Recorder's office.

                In no event shall this Lease be recorded by Tenant.


                                      -29-
<PAGE>   33

                33.11. Quiet Enjoyment. Upon paying the Rent and performing all
its obligations under this Lease, Tenant may peacefully and quietly enjoy the
Premises during the Term as against all persons or entities claiming by or
through Landlord, subject, however, to the provisions of this Lease and any
encumbrances as specified in Article 21.

                33.12. Surrender of Premises. Upon the Expiration Date or
earlier termination of this Lease, Tenant shall quietly and peacefully surrender
the Premises to Landlord in the condition specified in Article 9 above. On or
before the Expiration Date or earlier termination of this Lease, Tenant shall
remove all of its personal property from the Premises and repair at its cost and
expense all damage to the Premises or Building caused by such removal. All
personal property of Tenant not removed hereunder shall be deemed, at Landlord's
option, to be abandoned by Tenant and Landlord may store such property in
Tenant's name at Tenant's expense and/or dispose of the same in any manner
permitted by law.

                33.13. Building Directory. INTENTIONALLY DELETED.

                33.14. Name of Building; Address. Tenant shall not use the name
of the Building for any purpose other than as the address of the business
conducted by Tenant in the Premises. Tenant shall, in connection with all
correspondence, mail or deliveries made to or from the Premises, use the
official Building address specified from time to time by Landlord.

                33.15 Year 2000 Compliance. The Premises, Building and Land
shall meet all Year 2000 compliance requirements and the cost of such compliance
shall be at Landlord's sole expense.

                33.16. Exhibits. The Exhibits specified in the Basic Lease
Information are by this reference made a part hereof.

                33.17. Time of the Essence. Time is of the essence of this Lease
and of the performance of each of the provisions contained in this Lease.

                33.18. Reasonable Expenditures Any expenditure by a party
permitted or required under the Lease, for which such party demands
reimbursement from the other party, shall be limited to the fair market value of
the goods and services involved, shall be reasonably incurred, and shall be
substantiated by documentary evidence available for inspection and review by the
other party.



                IN WITNESS WHEREOF, the parties have executed this Lease as of
the Lease Date.

                          TENANT IMPROVEMENT AGREEMENT


        THIS TEN ANT IMPROVEMENT AGREEMENT ("Agreement") is made and entered
into by and between Landlord and Tenant as of the date of the Lease. This
Agreement shall be deemed a part of the Lease to which it is attached.
Capitalized terms which are used in this Agreement and defined in the Lease
shall have the meaning given in the Lease.

        1. General.

                1.1. The Parties' Respective Obligations. At Landlord's sole
cost and expense, in a good and workman like manner and in compliance with all
workplans and as-built plans approved by the City, Landlord shall construct the
Premises in "shell" condition which shall include only the work (the "Landlord's
Work") described on Schedule I attached to this Agreement and in those certain
plans prepared by Architecture Design Studio dated 10/5/99 (Delta 3 Set) Sheets
A0.1 through A10.2 and S-1 through S-21. At Tenant's sole cost and expense,
subject to the Construction Allowance described below, Landlord shall cause the
contractor (as defined below) to construct all initial leasehold improvements in
compliance with Final Plans (as defined below). The work which is to be
performed pursuant to Final Plans and this Agreement is referred to as the
"Tenant Improvements".

                1.2. Tenant Improvement Costs. The cost of performing the Tenant
Improvements, including without limitation the costs described in Section 6
below (collectively, the "Tenant Improvement Costs") shall be paid by Tenant in
the manner set forth in Section 5.

                1.3. Construction Allowance. In the manner provided in this
Section 5, Landlord shall provide an allowance for the Tenant Improvement Costs
in an amount equal to equal to Thirty and 00/100 Dollars ($30.00) multiplied by
the Rentable Area of the Premises (the "Construction Allowance"). If the cost of
Tenant Improvements is less than the Construction Allowance, Tenant shall be
entitled to a credit for any unused portion of the Construction Allowance in the
form of rent abatement of the rent first becoming due under the Lease.

        2. Approval of Plans for Tenant Improvements.

                2.1. Notification of Architect. Tenant hereby notifies Landlord
that it has engaged Richard Pollack & Associates having an address of 214 Grant
Street, San Francisco, California, who is licensed architect, as Tenant's
architect of record for the Tenant Improvements ("Architect"). Tenant's
Architect shall prepare plans for the Tenant Improvements and shall be retained
by Tenant for administrative services throughout the performance of Tenant
Improvements.

                2.2. Submittal of Plans.

                        2.2.1. Preliminary Plans. On or before November 19,
1999, Tenant shall deliver to Landlord, for Landlord's review and approval,
"Preliminary Plans" which shall include the following: (i) floor plans; (ii)
preliminary architectural finish schedule; and (iii) sufficient detail showing
the location of electrical, mechanical and plumbing to permit pricing. Within
five (5) business days after Landlord's receipt of Preliminary Plans, Landlord
shall either approve or disapprove Preliminary Plans, which approval shall not
be unreasonably withheld. Failure by Landlord to respond within such five (5)
day period shall be


                                       1
<PAGE>   38

conclusively deemed approval. If Landlord disapproves Preliminary Plans, then
Landlord shall state in reasonable detail the changes which Landlord requires to
be made thereto. Landlord hereby approves the description of the Tenant
Improvements attached as Schedule III hereto and shall not withhold consent to
the Preliminary Plans or the Final Plans to the extent the same are consistent
with such description and provided that the Tenant Improvements as described
therein will not materially adversely affect the structure of the Building, the
Building systems or the exterior of the Building nor violate any Laws or
Environmental Laws.

                        2.2.2. Preliminary Budget. Landlord shall retain a
third-party general contractor for the construction of the Tenant Improvements.
Tenant shall have the right to approve the fee for the general contractor and
the general conditions of the construction contract between Landlord and
Contractor for the construction of the Tenant Improvements, which approval shall
not be unreasonably withheld or delayed. Ten (10) days after approval by
Landlord and Tenant of Preliminary Plans, Contractor shall prepare a preliminary
budget for the Tenant Improvements based upon the approved Preliminary Plans,
which Contractor shall submit to Tenant for its review and approval. Within five
(5) days after Tenant's receipt of the preliminary budget, Tenant shall either
approve or disapprove the preliminary budget. If Tenant reasonably rejects such
preliminary budget, Tenant shall, within five (5) days of Tenant's delivery of a
written rejection notice to Landlord, require Architect to revise the
Preliminary Plans to reduce the cost of the Tenant Improvements. Following
Tenant's instructions to the Architect, Landlord and Tenant shall again follow
the procedures set forth in Section 2.2.1 and this Section 2.2.2 with respect to
the approval of the Preliminary Plans and to the submission and approval of the
preliminary budget from Contractor.

                        2.2.3. Final Plans. Within fifteen (15) business days
after Landlord and Tenant's approval of the preliminary budget for the Tenant
Improvements, Tenant shall cause the Architect to deliver to Landlord, for
Landlord's review and approval, complete plans, specifications and working
drawings which incorporate and are consistent with Preliminary Plans and the
preliminary budget, as previously approved by Landlord, and which show in detail
the intended design, construction and finishing of all portions of Tenant
Improvements, in sufficient detail for construction ("Final Plans"). Within ten
(10) business days after Landlord's receipt of Final Plans, Landlord shall
either approve or disapprove Final Plans, which approval shall not be
unreasonably withheld. If Landlord disapproves Final Plans, then Landlord shall
state in reasonable detail the changes which Landlord requires to be made
thereto. If Landlord disapproves the Final Plans, then Landlord shall state in
reasonable detail the changes which Landlord requires to be made thereto. Tenant
shall submit to Landlord revised Final Plans within five (5) business days after
Tenant's receipt of Landlord's disapproval notice. Following Landlord's receipt
of the revised Final Plans from Tenant, Landlord shall have the right to review
and approve the revised Final Plans pursuant to this Section 2.2.3. Landlord
shall give Tenant written notice of its approval or disapproval of the revised
Final Plans within five (5) business days after the date of Landlord's receipt
thereof. If Landlord reasonably disapproves the revised Final Plans, then the
following shall occur: (i) Landlord and Tenant shall continue to follow the
procedures set forth in this Section 2.2.3 until Landlord and Tenant reasonably
approve such Final Plans in accordance with this Section 2.2.3, and (ii) the
period between the date which is ten (10) business after Landlord's reasonable
disapproval (or such earlier date if Landlord approves or disapproves the first
revised Final Plans in a period less than the 5-business days provided Landlord
above) and the eventual mutual approval of such Final Plans shall constitute a
Tenant Delay.

                2.3. Landlord's Approval. Landlord's approval of any of Tenant's
plans, signs or materials samples shall not be valid unless such approval is in
writing and signed by Landlord, or otherwise deemed approved in accordance with
the provisions of Sections 2.2.1 and/or 2.2.3 of this Agreement. Landlord's
approval of any of Tenant's plans, including any preliminary draft or version
thereof, shall not be deemed to be a representation as to their completeness,
adequacy for Tenant's intended use of the Premises or


                                       2
<PAGE>   39

compliance with applicable law. Tenant shall pay to Landlord all reasonable
costs incurred by Landlord's architect in the review of Preliminary Plans and
Final Plans.

        3. Construction Budget. Upon approval by Landlord and Tenant of the
Final Plans, Tenant shall propose preferred subcontractors to Landlord in
certain trades which Landlord shall reasonably approve and in all other trades
Landlord shall propose acceptable subcontractors to Tenant which Tenant shall
reasonably approve and from such lists Landlord shall instruct Contractor to
obtain competitive bids for the Tenant Improvements from at least three (3)
subcontractors for each of the major subtrades and to submit the same to
Landlord and Tenant for their review and approval. Landlord shall select the
lowest bid unless Tenant agrees otherwise. Upon selection of the subcontractors
and approval of the bids, Contractor shall prepare a cost estimate for the
Tenant Improvements described in such Final Plans, based upon the bids submitted
by the subcontractors selected. Contractor shall submit such cost estimate to
Landlord and Tenant for their review and approval. Within five (5) days after
their receipt of the cost estimate, Landlord and Tenant shall each either
approve or disapprove the cost estimate, which approval shall not be
unreasonably withheld. Tenant's failure to approve or disapprove the cost
estimate within such 5-day period shall constitute grounds for the assertion of
a Tenant Delay. Landlord or Tenant may each approve or reject such cost estimate
in their reasonable sole discretion. If either Landlord or Tenant rejects such
cost estimate, Landlord shall resolicit bids based on such Final Plans, in
accordance with the procedures specified above. Following any resolicitation of
bids by Landlord pursuant to this Section 3, Landlord and Tenant shall again
follow the procedures set forth in this Section 3 with respect to the submission
and reasonable approval of the cost estimate from Contractor; provided, however
that the period between Tenant's disapproval of the first revised cost estimate
and the eventual mutual approval of a cost estimate shall constitute a Tenant
Delay. Tenant shall have the right to revise the Final Plans to reduce the
Tenant Improvement Costs but the time required to do so and delays in the
construction schedule as a result thereof shall constitute a Tenant Delay.

        4. Landlord to Construct. The construction contract shall specify and
Landlord shall use best efforts to cause Contractor to construct the Tenant
Improvements in a good and workmanlike manner, in accordance with the approved
Final Plans and in compliance with all applicable Laws. Architect shall be
responsible for promptly obtaining all necessary building permits and approvals
and other authorizations from governmental agencies required in connection with
the Tenant Improvements. The cost of all such permits and approvals, including
inspection and other building fees required to obtain the permits for the Tenant
Improvements, shall be included as part of the Tenant Improvement Costs. Tenant
shall have the benefit of any warranties provided by Contractor, the
subcontractors and suppliers in connection with the Tenant Improvements.
Landlord shall diligently prosecute construction of Landlord's Work and the
Tenant Improvements to completion. Landlord, Tenant, Contractor and Architect
shall hold weekly meetings to discuss the status of the construction. Landlord
shall provide Tenant with current construction schedules, including the
estimated date of completion.

        5. Payment for Tenant Improvements. The Tenant Improvement Costs shall
be paid solely by Tenant as follows:

                5.1 Method of Payment. Landlord shall bear the Tenant
Improvement Costs up to the amount of the Construction Allowance; and Tenant
shall be responsible for paying any excess in the Tenant Improvement Costs over
the amount of such Construction Allowance. For the purposes of this Agreement,
the term "Tenant's Share of Tenant Improvement Costs" shall mean the entire
amount of all Tenant Improvement Costs, less the Construction Allowance provided
by Landlord.

                        5.1.1. Payment. Within twenty (20) days after Landlord's
receipt of reasonably satisfactory invoices for costs of labor and materials
incurred in connection with the Tenant Improvements, together with such
supporting documentation and lien waivers as Landlord may


                                       3
<PAGE>   40

reasonably require in order to review the costs covered by the billing, Landlord
shall pay the Tenant Improvement Costs represented by such invoices first coming
due for payment, up to an aggregate amount equal to the Construction Allowance.
As and when any amount of Tenant's Share of Tenant Improvement Costs become due
and payable, Tenant shall pay such Tenant Improvement Costs to Landlord within
fourteen (14) days after the date of Tenant's receipt of Landlord's written
request therefor, together with such supporting documentation and lien waivers
as Tenant may reasonably require in order to review the costs covered by the
billing. Any failure by Tenant to pay any amount of Tenant's Share of Tenant
Improvement Costs as and when required under this Agreement shall constitute a
default by Tenant under the Lease after notice and applicable cure period
provided under the Lease. Notwithstanding the foregoing, Tenant may elect to
have Landlord finance Tenant's Share of Tenant Improvement Costs in an amount up
to Five and 00/100 ($5.00) per square foot of Rentable Area by amortizing the
Tenant's Share of Tenant Improvement Costs over the Initial Term at an interest
rate of ten percent (10%) per annum. Tenant shall make such election within five
(5) days of the approval of the construction budget pursuant to Sections 2 and 3
and within ten (10) days following such election, Landlord and Tenant shall
enter into an amendment to the Lease providing for the increase in Base Rent.

                        5.1.2. Penalties. To the extent that any contractor or
subcontractor working on the Tenant Improvements imposes upon Landlord any
penalty or late charge due to Tenant's failure to pay to Landlord any amount due
under this Section 5.1 as and when such amount is due, Tenant shall be solely
responsible for paying such penalty or late charge; provided, however, that if
Tenant disputes the imposition of such penalty or late charge, Tenant shall not
be required to pay the penalty or late charge until the dispute has been settled
or otherwise resolved; provided further, that if any penalty or late charge is
imposed due to Tenant's exercise of its rights under this Section 5.1.3, Tenant
shall pay such penalty or late charge as provided in this Section 5.1.3.

                5.2 Extra Work. Tenant shall be solely responsible for any and
all costs and expenses arising from any improvements to or installations in the
Building desired by Tenant and approved by Landlord that are outside the scope
of the Final Plans.

        6. Tenant Improvement Costs. The Tenant Improvement Costs shall include
all reasonable costs incurred in connection with the Tenant Improvements, as
determined by Landlord in its reasonable discretion, including the following:

                6.1 All costs of space plans and other architectural and
engineering plans and specifications for the Tenant Improvements, including
engineering costs associated with completion of the State of California energy
utilization calculations under Title 24 legislation required in connection with
the Tenant Improvements; provided however that only Two and 50/100 Dollars
($2.50) per square foot of Rentable Area for such costs may be allocated to the
construction allowance and any costs in excess thereof shall be allocated to
Tenant's Share of Tenant's Improvement Costs.

billing for such additional costs shall be accompanied by evidence of the
amounts billed as is customarily used in the business. Costs related to changes
shall include, without limitation, any architectural, structural engineering, or
design fees, and the Contractor's price for effecting the change. Any change
order which may extend the date of substantial completion of the Tenant
Improvements may be disapproved by Landlord unless Tenant agrees that for all
purposes under this Lease, the Tenant Improvements shall be deemed to have been
substantially completed on that date on which such Tenant Improvements would
have been substantially completed without giving effect to the change order in
question. All change orders shall specify any change in the cost estimate as a
consequence of the change order.

after the date that all of the following have occurred: (i) Landlord shall
certify in writing that Contractor has substantially completed the Landlord's
Work and the Tenant Improvements, notwithstanding that minor details of
construction, mechanical adjustment or decorations which do not materially

Landlord's Work discovered within six (6) months after the Possession Date. Any
damage to the Building caused by Tenant's move-in shall be repaired or corrected
by Tenant, at its sole cost and expense, which repair or corrective work shall

                                  OFFICE LEASE


               THIS LEASE is made and entered into by and between Landlord and
Tenant as of the Lease Date. Landlord and Tenant hereby agree as follows:

        1. Definitions.

               1.1. Terms Defined. The following terms have the meanings set
forth below. Certain other terms have the meanings set forth in the Basic Lease
Information or elsewhere in this Lease.

                      Alterations: Alterations, additions or other improvements
to the Premises made by Tenant or its employees or contractors (but not
including the alterations, additions or other improvements, if any, made by or
on behalf of Tenant during the initial improvement of the Premises pursuant to
and governed by the provisions of the Work Letter).

                      Base Operating Expenses and Base Real Estate Taxes: The
Operating Expenses and the Real Estate Taxes paid or incurred by Landlord in the
Base Year.

                      Building: The office building, and surrounding property,
consisting of a four-story building located on the Land, commonly known as 33
Clementina Street, San Francisco, California, and any additions to such
Building.

                      Escalation Rent: The total dollar increase, if any, in
Operating Expenses and in Real Estate Taxes, each as paid or incurred by
Landlord in each calendar year, or part thereof, after the Base Year, over the
amount of Base Operating Expenses and Base Real Estate Taxes. For purposes of
determining Operating Expenses for the Base Year, since the Building will be
less than ninety-five percent (95%) occupied during the Base Year, Landlord
shall make an appropriate adjustment of the variable components of Operating
Expenses for that year, as reasonably determined by Landlord using sound
accounting and management principles, to determine the amount of Operating
Expenses that would have been incurred during such year if the Building had been
ninety-five percent (95%) occupied during the entire year. This amount shall be
considered to have been the amount of Operating Expenses for the Base Year. For
purposes hereof, "variable components" include only those component expenses
that are affected by variations in occupancy levels. For purposes of determining
Real Estate Taxes for the Base Year, Landlord shall make an appropriate
adjustment to the Real Estate Taxes for such year as reasonably determined by
Landlord using sound accounting and management principles, to determine the
amount of Real Estate Taxes that would have been incurred during such year if
the tenant improvements in the Building had been fully constructed and the Land,
the Building, and all tenant improvements in the Building had been fully
assessed for Real Estate Tax purposes.


                      Impositions: Taxes, assessments, charges, excises and
levies, business taxes, licenses, permits, inspection and other authorization
fees, transit development fees, assessments or charges for housing funds,
service payments in lieu of taxes and any other fees or charges of any kind at
any time levied, assessed, charged or imposed by any federal, state or local
entity, upon, measured by or reasonably attributable to the cost or value of
Tenant's equipment, furniture, fixtures or other personal property located in
the Premises, or the cost or value of any alterations, additions or other
improvements to the Premises made by or on behalf of Tenant during the initial
improvement of the Premises pursuant to and governed by the Work Letter which
exceed Building standard improvements (which for purposes of this definition are
defined


                                       1


<PAGE>   5
to mean tenant improvements costing less than $50.00 per square foot of Rentable
Area) and any subsequent Alterations. Impositions do not include Real Estate
Taxes, franchise, transfer, inheritance or capital stock taxes, or income taxes
measured by the net income of Landlord from all sources, unless any such taxes
are levied or assessed against Landlord as a substitute for, in whole or in
part, any Imposition.

under clause (iv) above); (K) all costs arising from monitoring, cleaning up and

all similar amounts payable by Tenant; and (C) penalties, fines, interest or

                      Rent: Base Rent, Escalation Rent and all other additional
charges and amounts payable by Tenant in accordance with this Lease.

                      Term: The period from the Possession Date to the
Expiration Date.

        2. Lease of Premises. Landlord leases to Tenant and Tenant leases from
Landlord the Premises.

        3. Term; Condition and Acceptance of Premises.

               3.1 Initial Term and Acceptance of Premises. Except as
hereinafter provided, and unless sooner terminated pursuant to the provisions of
this Lease, the Term of this Lease shall commence on the Possession Date and end
on the Expiration Date. Landlord shall deliver the Premises to Tenant on the
Possession Date in the condition required by the Work Letter. To the extent that
(i) Landlord has agreed in the Work Letter to make any alterations or
improvements to the Premises prior to the Possession Date, (ii) Tenant desires
to take occupancy of the Premises in advance of the Possession Date, and (iii)
Landlord determines in its sole discretion that Tenant's early occupancy shall
not delay the completion of the improvements to the Premises, then Landlord
shall deliver the Premises to Tenant in advance of the Possession Date on a date
mutually agreed upon by Landlord and Tenant. If Landlord, for any reason
whatsoever, is delayed in the delivery of the Premises to Tenant, this Lease
shall not be void or voidable, and Landlord shall not be in default or liable to
Tenant for any loss or damage resulting therefrom: provided, however, that if
the Possession Date does not occur on or before January 1, 2001, then Tenant
shall have the


                                       3


<PAGE>   7
right to terminate this Lease by delivering written notice to Landlord at any
time before February 1, 2002, whereupon any monies previously paid by Tenant to
Landlord shall be reimbursed to Tenant. Within five (5) days after the
Possession Date, Landlord and Tenant shall execute a Confirmation of Lease Term
in the form as set forth in Exhibit E attached to this Lease. Tenant's occupancy
of all or any portion of the Premises shall constitute Tenant's acceptance of
the Premises in the condition called for by this Lease. Tenant's occupancy of
all or any portion of the Premises shall constitute Tenant's acceptance of the
Premises in the condition called for by this Lease, subject to the punchlist
items as described in the Work Letter. Notwithstanding the foregoing, if the
Possession Date occurs after September 1, 2000 as a result of events other than
delays caused by the acts or omissions of Tenant, or Tenant's contractors,
employees or agents ("Tenant Delays"), then the "Commencement Date" shall be a
date calculated as follows: (i) two (2) weeks after the Possession Date, plus
(ii) the number of days by which the Possession Date exceeds September 1, 2000,
minus (iii) the number of days of delay that Landlord is actually delayed in
delivering the Premises to Tenant caused by Tenant Delays.


               3.2 Option to Extend.

                      3.2.1. Exercise of Option to Extend Term. If no
"Suspension Condition" (as hereinafter defined) exists at the time of Tenant's
exercise of the option to extend the Initial Term or at the commencement of the
Extended Term, as the case may be, Tenant shall have two (2) options (each an
"Extension Option") to extend the Initial Term for an additional period of five
(5) years each (each an "Extended Term"). To exercise Tenant's option with
respect to the Extended Term, Tenant shall give notice to Landlord not less than
two hundred ten (210) days prior to the expiration of the Initial Term, or the
first Extended Term ("Election Notice"). A "Suspension Condition" shall mean the
existence of any event or condition of default after expiration of any
applicable grace, notice or cure periods. Tenant shall have no right to exercise
the second Extension Option unless Tenant properly exercised the first Extension
Option.

                      3.2.2. Fair Market Rent. If Tenant properly and timely
exercises Tenant's option to extend pursuant to Section 3.2.1 above, such
extension shall be upon all of the same terms, covenants and conditions of this
Lease; provided, however, that the Base Rent applicable to the Premises for each
Extended Term shall be one hundred percent (100%) of the "Fair Market Rent" for
space comparable to the Premises as of the commencement of the applicable
Extended Term. "Fair Market Rent" shall mean the annual rental being charged for
first class space comparable to the Premises in buildings comparable to the
Building in the south of Market and financial districts of San Francisco, taking
into account location, parking, condition and improvements to the space and the
fact that Tenant is not entitled to rent concessions or a tenant improvement
allowance. All other terms and conditions of the Lease, which may be amended
from time to time by the parties in accordance with the provisions of the Lease,
shall remain in full force and effect and shall apply during each Extended Term,
as applicable, except that: (i) there shall be no further option to extend the
Term beyond a date ten (10) years after the expiration of the Initial Term, (ii)
there shall be no further rent concessions, and (iii) there shall be no tenant
improvement allowance or similar provisions.

                      3.2.3. Determination of Rent. Within thirty (30) days
after the date of the Election Notice, Landlord and Tenant shall negotiate in
good faith in an attempt to determine Fair Market Rent for the Extended Term. If
they are unable to agree within said thirty (30) day period, then the Fair
Market Rent shall be determined as provided in Section 3.2.4 below, unless on or
before such thirtieth (30th) day after the date of the Election Notice Tenant
provides Landlord with written notice of its election to revoke the Election
Notice and to not exercise its option to extend.

                      3.2.4. Appraisal. If it becomes necessary to determine the
Fair Market Rent for the Premises by appraisal, the real estate appraiser(s)
indicated in this Section 3.2.4, each of whom shall be


                                       4


<PAGE>   8
members of the Appraisal Institute and each of whom have at least five (5) years
experience appraising office space located in the vicinity of the Premises,
shall be appointed and shall act in accordance with the following procedures:

                      (i) If the parties are unable to agree on the Fair Market
Rent within the allowed time, either party may demand an appraisal by giving
written notice to the other party, which demand to be effective must state the
name, address and qualifications of an appraiser selected by the party demanding
the appraisal ("Notifying Party"). Within ten (10) days following the Notifying
Party's appraisal demand, the other party ("Non-Notifying Party") shall either
approve the appraiser selected by the Notifying Party or select a second
properly qualified appraiser by giving written notice of the name, address and
qualification of said appraiser to the Notifying Party. If the Non-Notifying
Party fails to select an appraiser within the ten (10) day period, the appraiser
selected by the Notifying Party shall be deemed selected by both parties and no
other appraiser shall be selected. If two (2) appraisers are selected, they
shall select a third appropriately qualified appraiser. If the two (2)
appraisers fail to select a third qualified appraiser, the third appraiser shall
be appointed by the then presiding judge of the county where the Premises are
located upon application by either party.

                      (ii) If only one appraiser is selected, that appraiser
shall notify the parties in simple letter form of its determination of the Fair
Market Rent for the Premises within fifteen (15) days following his or her
selection, which appraisal shall be conclusively determinative and binding on
the parties as the appraised Fair Market Rent.

                      (iii) If multiple appraisers are selected, the appraisers
shall meet not later than ten (10) days following the selection of the last
appraiser. At such meeting, the appraisers shall attempt to determine the Fair
Market Rent for the Premises as of the commencement date of the Extended Term in
question by the agreement of at least two (2) of the appraisers.

                      (iv) If two (2) or more of the appraisers agree on the
Fair Market Rent for the Premises at the initial meeting, such agreement shall
be determinative and binding upon the parties hereto and the agreeing appraisers
shall forthwith notify both Landlord and Tenant of the amount set by such
agreement. If multiple appraisers are selected and two (2) appraisers are unable
to agree on the Fair Market Rent for the Premises, each appraiser shall submit
to Landlord and Tenant his or her respective independent appraisal of the Fair
Market Rent for the Premises, in simple letter form, within twenty (20) days
following appointment of the final appraiser. The parties shall then determine
the Fair Market Rent for the Premises by averaging the appraisals; provided that
any high or low appraisal, differing from the middle appraisal by more than ten
percent (10%) of the middle appraisal, shall be disregarded in calculating the
average.

                      (v) If only one (1) appraiser is selected, then each party
shall pay one-half (1/2) of the fees and expenses of that appraiser. If three
(3) appraisers are selected, each party shall bear the fees and expenses of the
appraiser it selects and one-half (1/2) of the fees and expenses of the third
appraiser.

                      3.2.5. Restriction on Assignment. The Extension Option
shall be personal to Critical Path or any Related Entity (defined below), shall
not be assignable or transferable, shall terminate upon any assignment of the
Premises other than to a Related Entity and or any sublease that results in
Tenant or a Related Entity retaining a portion of the Premises that is less than
fifty percent (50%) of the Rentable Area of the original Premises

                      3.2.6. Amendment to Lease. Immediately after the Fair
Market Rent has been determined, the parties shall enter into an amendment to
this Lease setting forth the Base Rent for the Extended Term and shall also
state the new Expiration Date of the Term of the Lease.


                                       5


<PAGE>   9
               3.3 Right to Terminate. Tenant shall have the right to terminate
this Lease effective at the end of the seventh year following the Commencement
Date (the "Early Termination Date") provided that Tenant delivers written notice
to Landlord at least 180 days prior to the Early Termination Date and that on or
before the Early Termination Date Tenant pays to Landlord a termination fee in
an amount equal to the unamortized (amortized on a straight line basis over the
Initial Term) Tenant Allowance (as defined in the Work Letter) and brokerage fee
paid by Landlord to the Brokers at the time this Lease is executed and at the
time the Tenant takes possession of the Premises.

        4. Rent.

               4.1. Obligation to Pay Base Rent. Tenant shall pay Base Rent to
Landlord, in advance, in equal monthly installments, commencing on the
Commencement Date, and thereafter on or before the first day of each calendar
month during the Term. If the Commencement Date and/or Expiration Date is other
than the first day of a calendar month, the installment of Base Rent for the
first and/or last fractional month of the Term shall be prorated on a daily
basis. Not less than thirty (30) days prior to the Commencement Date, Tenant
shall pay to Landlord the first month's Base Rent.

               4.2. Manner of Rent Payment. All Rent shall be paid by Tenant
without notice, demand, abatement, deduction or offset (except as expressly set
forth herein), in lawful money of the United States of America, payable to
Landlord, at Landlord's Address as set forth in the Basic Lease Information, or
to such other person or at such other place as Landlord may from time to time
designate by notice to Tenant.

               4.3. Additional Rent. All Rent not characterized as Base Rent or
Escalation Rent shall constitute additional rent, and if payable to Landlord
shall, unless otherwise specified in this Lease, be due and payable thirty (30)
days after Tenant's receipt of Landlord's invoice therefor.

               4.4. Late Payment of Rent; Interest. Tenant acknowledges that
late payment by Tenant of any Rent will cause Landlord to incur administrative
costs not contemplated by this Lease, the exact amount of which are extremely
difficult and impracticable to ascertain based on the facts and circumstances
pertaining as of the Lease Date. Accordingly, if any Rent is not paid by Tenant
when due, a late charge equal to five percent (5%) of such Rent; provided,
however, that the following additional provisions shall apply to such late
charge: (i) the first late payment in any calendar year shall not result in any
late charge payment unless such payment of Rent is not received within two (2)
business days after Landlord's delivery of written notice to Tenant, and (ii) if
there are more than two (2) late payments of Rent by Tenant in any calendar
year, then the late charge for each subsequent late payment in such calendar
year shall be eight percent (8%). Any Rent, other than late charges, due
Landlord under this Lease, if not paid when due, shall also bear interest from
the date due until paid, at the lesser of the rate of ten percent (10%) per
annum and the highest rate legally permitted. The parties acknowledge that such
late charge and interest represent a fair and reasonable estimate of the
administrative costs and loss of use of funds Landlord will incur by reason of a
late Rent payment by Tenant, but Landlord's acceptance of such late charge
and/or interest shall not constitute a waiver of Tenant's default with respect
to such Rent or prevent Landlord from exercising any other rights and remedies
provided under this Lease, at law or in equity.

        5. Calculation and Payments of Escalation Rent. During each full or
partial calendar year of the Term subsequent to the Base Year, Tenant shall pay
to Landlord Escalation Rent in accordance with the following procedures:

               5.1. Payment of Estimated Escalation Rent. During December of the
Base Year and


                                       6


<PAGE>   10
December of each subsequent calendar year, or as soon thereafter as practicable,
Landlord shall give Tenant notice of its estimate of Escalation Rent due for the
next ensuing calendar year. On or before the first day of each month during such
next ensuing calendar year, Tenant shall pay to Landlord in advance, in addition
to Base Rent, one-twelfth (1/12th) of such estimated Escalation Rent. In the
event such notice is given after December 31st of any year during the Term, (i)
Tenant shall continue to pay Escalation Rent on the basis of the prior calendar
year's estimate until the month after such notice is given, (ii) subsequent
payments by Tenant shall be based of the estimate of Escalation Rent set forth
in Landlord's notice, and (iii) with the first monthly payment of Escalation
Rent based on the estimate set forth in Landlord's notice, Tenant shall also pay
the difference, if any, between the amount previously paid for such calendar
year and the amount which Tenant would have paid through the month in which such
notice is given, based on Landlord's noticed estimate or, in the alternative, if
such amount previously paid by Tenant for such calendar year through the month
in which such notice is given exceeds the amount which Tenant would have paid
through such month based on Landlord's noticed estimate, Landlord shall credit
such excess amount against the next monthly payments of Escalation Rent due from
Tenant. If at any time Landlord reasonably determines that the Escalation Rent
for the current calendar year will vary from Landlord's estimate by more than
five percent (5%), Landlord may, by notice to Tenant not more than once a
calendar year, revise its estimate for such calendar year, and subsequent
payments by Tenant for such calendar year shall be based upon such revised
estimate. Notwithstanding anything to the contrary contained herein, Tenant may
pay the portion of Escalation Rent attributable to Real Estate Taxes as set
forth in Landlord's notice of its estimate of Escalation Rent on or before a
date thirty (30) days prior to the date such Real Estate Taxes are due, unless
Landlord notifies Tenant that its lender is requiring Landlord to escrow Real
Estate Taxes pursuant to a deed of trust encumbering the Premises.

               5.2. Escalation Rent Statement and Adjustment. Within one hundred
twenty (120) days after the close of each calendar year, or as soon thereafter
as practicable, Landlord shall deliver to Tenant a statement of the actual
Escalation Rent for such calendar year, accompanied by a statement prepared by
Landlord showing in reasonable detail the Operating Expenses and the Real Estate
Taxes comprising the actual Escalation Rent. If Landlord's statement shows that
Tenant owes an amount less than the payments previously made by Tenant for such
calendar year, Landlord shall credit the difference first against any sums then
owed by Tenant to Landlord and then against the next payment or payments of Rent
due Landlord within thirty (30) days, except that if a credit amount is due
Tenant after termination of this Lease, Landlord shall pay to Tenant any excess
remaining after Landlord credits such amount against any sums owed by Tenant to
Landlord. If Landlord's statement shows that Tenant owes an amount more than the
payments previously made by Tenant for such calendar year, Tenant shall pay the
difference to Landlord within thirty (30) days after delivery of the statement.

               5.3. Proration for Partial Year. If this Lease terminates other
than on the last day of a calendar year (other than due to Tenant's default),
the amount of Escalation Rent for such fractional calendar year shall be
prorated on a daily basis. Upon such termination, Landlord may, at its option,
calculate the adjustment in Escalation Rent prior to the time specified in
Section 5.2 above. Tenant's obligation to pay Escalation Rent and Landlord's
obligation to reimburse excess amounts as set forth in Section 5.2, above, shall
survive the expiration or termination of this Lease.

               5.4. Tenant's Right to Contest Taxes If Real Estate Taxes are not
contested by Landlord, Tenant shall have the right to contest such Taxes, at no
cost or expense to Landlord, by the appropriate proceedings diligently contested
in good faith. Notwithstanding such proceedings, the contested Real Estate Taxes
shall be promptly paid and discharged, unless such proceedings (and where
necessary the posting of any appropriate bond or other security) shall operate
to prevent or stay the collection of the Real Estate Taxes and secure any
accruing penalties or interest and such proceedings shall provide a cure of
Landlord's default in the payment of Real Estate Taxes required under any deed
of trust upon the


                                       7


<PAGE>   11
Premises. Landlord shall join Tenant in such proceedings, if necessary, provided
that Tenant pays all reasonable costs and expenses incurred by Landlord.

        6. Impositions Payable by Tenant. Tenant shall pay all Impositions prior
to delinquency. If billed directly to Tenant, Tenant shall pay such Impositions
and concurrently deliver to Landlord evidence of such payments. If any
Impositions are billed to Landlord or included in bills to Landlord for Real
Estate Taxes or other charges, then Tenant shall pay to Landlord all such
amounts within twenty (20) days after delivery of Landlord's invoice therefor.
If applicable law prohibits Tenant from reimbursing Landlord for an Imposition,
but Landlord may lawfully increase the Base Rent to account for Landlord's
payment of such Imposition, the Base Rent payable to Landlord shall be increased
to net to Landlord the same return without reimbursement of such Imposition as
would have been received by Landlord with reimbursement of such Imposition.
Tenant's obligation to pay Impositions which have accrued and remain unpaid upon
the expiration or earlier termination of this Lease shall survive the expiration
or earlier termination of this Lease.

        7. Use of Premises.

               7.1. Permitted Use. The Premises may only be used solely for the
Permitted Use and for no other use or purpose.

               7.2. No Violation of Legal and Insurance Requirements. Tenant
shall not do or knowingly permit to be done, or bring or keep or knowingly
permit to be brought or kept, in or about the Premises, or any other portion of
the Building, anything which (i) is prohibited by or will in any way conflict
with any law, ordinance, rule or regulation; (ii) would invalidate or be in
conflict with the provisions of any insurance policy carried by Landlord or
Tenant on any portion of the Building or Premises, or any property therein; or
(iii) would cause a cancellation of any such insurance, increase the existing
rate of or affect any such Landlord's insurance (unless Tenant pays an increase
in premium), or subject Landlord to any liability or responsibility for injury
to any person or property. If Tenant does or knowingly permits anything to be
done which increases the cost of any of Landlord's insurance, or which results
in the need, in Landlord's reasonable judgment, for additional insurance by
Landlord or Tenant with respect to any portion of the Building or Premises, then
after prior written notice to Tenant of such action Tenant shall reimburse
Landlord, upon demand, for any such additional costs or the costs of such
additional insurance, and/or procure such additional insurance at Tenant's sole
cost and expense. Exercise by Landlord of such right to require reimbursement of
additional costs (including the costs of procuring of additional insurance)
shall not limit or preclude Landlord from prohibiting Tenant's impermissible use
of the Premises or from invoking any other right or remedy available to Landlord
under this Lease.

               7.3. Compliance with Legal, Insurance and Life Safety
Requirements. Except as provided in clauses (i) through (iii) below, Tenant, at
its cost and expense, shall promptly comply with all laws, ordinances, rules,
regulations, orders and other governmental requirements, the requirements of any
board of fire underwriters or other similar body, any directive or occupancy
certificate issued pursuant to any law by any public officer or officers, the
provisions of all recorded documents affecting any portion of the Building and
all life safety programs, procedures and rules implemented or promulgated by
Landlord in its reasonable judgement pertaining to Tenant's use of the Premises
in order to comply with applicable laws, ordinances, rules, regulations, orders
or governmental requirements or requirements of insurance underwriters ("Laws").
Tenant shall not, however, be required to comply with Laws requiring Tenant to
make structural changes or capital improvements to the Premises unless
necessitated, in whole or in part, by (i) Tenant's particular use or occupancy
of the Premises, or (ii) Alterations (excluding any alterations, additions or
other improvements to the Premises made by or on behalf of Tenant during the


                                       8


<PAGE>   12
initial improvement of the Premises pursuant to the Work Letter).

               7.4. No Nuisance. Tenant shall not (i) do or permit anything to
be done in or about the Premises, or any other portion of the Building, which
would injure or annoy, or obstruct or interfere with the rights of, Landlord or
other occupants of the Building, or others lawfully in or about the Building;
(ii) use or allow the Premises to be used in any manner inappropriate for a
Class A office building, or for any improper or objectionable purposes; or (iii)
cause, maintain or permit any nuisance or waste in, on or about the Premises, or
any other portion of the Building.

               7.5. Hazardous Substances. The term "Hazardous Substances" as
used in the Lease, is defined as follows:

        Any element, compound, mixture, solution, particle or substance, which
        presents danger or potential danger of damage or injury to health,
        welfare or to the environment including, but not limited to: (i) those
        substances which are inherently or potentially radioactive, explosive,
        ignitable, corrosive, reactive, carcinogenic or toxic and (ii) those
        substances which have been recognized as dangerous or potentially
        dangerous to health, welfare or to the environment by any federal,
        municipal, state, county or other governmental or quasi-governmental
        authority and/or any department or agency thereof.

               Tenant represents and warrants to Landlord and agrees that at all
times during the term of this Lease and any extensions or renewals thereof,
Tenant shall:

               (i) promptly comply at Tenant's sole cost and expense, with all
        laws, orders, rules, regulations, certificates of occupancy, or other
        requirements, as the same now exist or may hereafter be enacted, amended
        or promulgated, of any federal, municipal, state, county or other
        governmental or quasi-governmental authorities and/or any department or
        agency thereof relating to the manufacturing, processing, distributing,
        using, producing, treating, storing (above or below ground level),
        disposing or knowingly allowing to be present(the "Environmental
        Activity") of Hazardous Substances in or about the Premises (each, an
        "Environmental Law", and all of them, "Environmental Laws") to the
        extent Tenant is responsible for the presence of such Hazardous
        Substances.

               (ii) indemnify and hold Landlord, its agents and employees,
        harmless from any and all demands, claims, causes of action, penalties,
        liabilities, judgments, damages (including consequential damages) and
        expenses including, without limitation, court costs and reasonable
        attorneys' fees incurred by Landlord as a result of (a) Tenant's failure
        or delay in properly complying with any Environmental Law as required by
        clause (i) above, or (b) any adverse effect which results from the
        Environmental Activity by Tenant, Tenant's subtenants or any of their
        respective agents, employees or contractors, whether Tenant or Tenant's
        subtenants or any of their respective agents, employees, contractors or
        invitees has caused such Environmental Activity, with or without
        Tenant's consent, , or either intentionally or unintentionally. If any
        action or proceeding is brought against Landlord, its agents or
        employees by reason of any such claim, Tenant, upon notice from
        Landlord, will defend such claim at Tenant's expense with counsel
        reasonably satisfactory to Landlord. This indemnity obligation by Tenant
        of Landlord will survive the expiration or earlier termination of this
        Lease.

               (iii) promptly disclose to Landlord by delivering, in the manner
        prescribed for delivery of notice in this Lease, a copy of any forms,
        submissions, notices, reports, or other written documentation (each, a
        "Communication") relating to any Environmental Activity, whether any


                                       9


<PAGE>   13
        such Communication is delivered to Tenant or any of its subtenants or is
        requested of Tenant or any of its subtenants by any federal, municipal,
        state, county or other government or quasi-governmental authority and/or
        any department or agency thereof.

               (iv) in the event there is a release of any Hazardous Substance
        as a result of or in connection with any Environmental Activity by
        Tenant or any of Tenant's subtenants or any of their respective agents,
        employees, contractors or invitees, which must be remediated under any
        Environmental Law, Landlord shall perform the necessary remediation; and
        Tenant shall reimburse Landlord for all costs thereby incurred within
        fifteen (15) days after delivery of a written demand therefor from
        Landlord (which shall be accompanied by reasonable substantiation of
        such costs). In the alternative, Landlord shall have the right to
        require Tenant, at its sole cost and expense, to perform the necessary
        remediation in accordance with a detailed plan of remediation which
        shall have been approved in advance in writing by Landlord. Landlord
        shall give notice to Tenant within thirty (30) days after Landlord
        receives notice or obtains knowledge of the required remediation. The
        rights and obligations of Landlord and Tenant set forth in this clause
        (iv) shall survive the expiration or earlier termination of this Lease.

               (v) notwithstanding any other provisions of this Lease, allow
        Landlord, and any authorized representative of Landlord, access and the
        right to enter and inspect the Premises for Environmental Activity, at
        any time deemed reasonable by Landlord, upon prior notice to Tenant on
        the terms set forth in Article 19.

Compliance by Tenant with any provision of this Section 7.5 shall not be deemed
a waiver of any other provision of this Lease. Without limiting the foregoing,
Landlord's consent to any Environmental Activity shall not relieve Tenant of its
indemnity obligations under the terms hereof.

               Except as set forth in the Phase I Environmental Assessment dated
January 22, 1996 prepared by William Dubovsky Environmental and that certain
letter dated April 12, 1999 prepared by William Dubovsky Environmental,, to
Landlord's knowledge, (a) no Hazardous Substance is present on the Building or
the soil, surface water or groundwater of the Land, (b) no underground storage
tanks are present on the Land, and (c) no action proceeding or claim is pending
or threatened regarding the Building concerning any Hazardous Substance or
pursuant to any Environmental Law. Landlord shall promptly remedy and shall
indemnify, defend, protect and hold harmless Tenant, its agents, contractors,
stockholders, directors, successors, representatives, and assigns from and
against, all losses, costs, claims, liabilities and damages (including
attorneys' and consultants' fees) of every type and nature, directly or
indirectly arising out of or in connection with any Hazardous Substance present
at any time on or about the Building, or the soil, air, improvements,
groundwater or surface water of the Land, or the violation of any Environmental
Laws, except to the extent that any of the foregoing results from the
Environmental Activity by Tenant or any of Tenant's subtenants or any of their
respective agents, employees, contractors or invitees, in violation of
Environmental Laws.


               This Section 7.5 of the Lease constitutes the entire agreement of
Landlord and Tenant regarding Hazardous Substances.

               7.6. Special Provisions Relating to The Americans With
Disabilities Act of 1990.

                      7.6.1. Allocation of Responsibility to Landlord. As
between Landlord and Tenant, Landlord shall be responsible that the Building as
of the Commencement Date complies with the requirements of Title III of the
Americans with Disabilities Act of 1990 (42 U.S.C. 12181, et seq., The
Provisions Governing Public Accommodations and Services Operated by Private
Entities), and all


                                       10


<PAGE>   14
regulations promulgated thereunder, and all amendments, revisions or
modifications thereto now or hereafter adopted or in effect in connection
therewith (hereinafter collectively referred to as the "ADA"), and to take such
actions and make such alterations and improvements as are necessary for such
compliance. All costs incurred by Landlord in discharging its responsibilities
under this Section 7.6.1 shall be included in Operating Expenses to the extent
permitted by Section 1.1.

                      7.6.2. Allocation of Responsibility to Tenant. As between
Landlord and Tenant, Tenant, at its sole cost and expense, shall be responsible
that all Alterations to the Premises (excluding any alterations, additions or
other improvements to the Premises made by or on behalf of Tenant during the
initial improvement of the Premises pursuant to the Work Letter), Tenant's
particular use and occupancy of the Premises, and Tenant's performance of its
obligations under this Lease, comply with the requirements of the ADA, and to
take such actions and make such Alterations as are necessary for such
compliance; provided, however, that Tenant shall not make any such Alterations
except upon Landlord's prior written consent pursuant to the terms and
conditions of this Lease. Tenant shall protect, defend, indemnify and hold
Landlord harmless from and against any claim, demand, cause of action,
obligation, liability, loss, cost or expense (including reasonable attorneys'
fees) which may be asserted against or incurred by Landlord as a result of
Tenant's failure in any respect to comply with its obligations set forth in this
Section 7.6.2. Tenant's indemnity obligations set forth in the immediately
preceding sentence shall survive the expiration or earlier termination of this
Lease.

                      7.6.3. General. Notwithstanding anything in this Lease to
the contrary, no act or omission of Landlord, including any approval, consent or
acceptance by Landlord or Landlord's agents, employees or other representatives,
shall be deemed an agreement, acknowledgment, warranty, or other representation
by Landlord that Tenant has complied with the ADA or that any action, alteration
or improvement by Tenant complies or will comply with the ADA or constitutes a
waiver by Landlord of Tenant's obligations to comply with the ADA under this
Lease or otherwise. Any failure of Landlord to comply with the obligations of
the ADA shall not relieve Tenant from any obligations under this Lease or
constitute or be construed as a constructive or other eviction of Tenant or
disturbance of Tenant's use and possession of the Premises.

        8. Building Services.

               8.1. Maintenance of Building. Except as provided in Section 9,
Landlord shall maintain the Building in good order and condition, except for
ordinary wear and tear, damage by casualty or condemnation, or damage occasioned
by the act or omission of Tenant or Tenant's employees, agents, contractors,
licensees or invitees, which damage by Tenant or Tenant's employees, agents,
contractors, licensees or invitees shall be repaired by Landlord at Tenant's
expense. Landlord shall perform and construct, and Tenant shall have no
responsibility to perform or construct, any repair, maintenance or improvements
(a) to the roof or the structural portions of the Building, (b) which could be
treated as a "capital expenditure" under generally accepted accounting
principles, (c) to the heating, ventilating, air conditioning, electrical, fire
and life safety, water, sewer, and plumbing systems serving the Premises and the
Building, (d) to any exterior or other portion of the Land outside of the
demising walls of the Premises, (e) due to negligent acts or omissions of
Landlord or (f) for which Landlord has a right of reimbursement. Notwithstanding
the foregoing, Tenant shall pay for its share of the repairs described above to
the extent such costs are properly included in Operating Expenses.Landlord's
maintenance of, and provision of services to, the Building shall be performed in
a manner consistent with that of comparable office buildings in the San
Francisco, California area. Landlord shall not be in default under this Lease or
liable for any damages directly or indirectly resulting from or incidental to,
nor shall the rental reserved in this Lease be abated by reason of, Landlord's
failure to make any repair or to perform any maintenance required to be made or
performed by Landlord under this Section 8.1, except as otherwise provided in
Section 20.6 or unless such failure shall persist for


                                       11


<PAGE>   15
an unreasonable time after written notice of the need for such repair or
maintenance is given to Landlord by Tenant; provided, however, that Landlord
shall be liable only to Tenant for actual, out of pocket, costs or expenses
incurred by Tenant as a direct result of Landlord's failure to cause the floor
lobby or elevators of the Building to comply with laws which are immediately
applicable to, and enforceable against, the Building (subject to Landlord's
reasonable right of contest of such laws).


               8.2. Building Standard Services. During the Term, the Premises
shall be furnished with water, gas, electricity and heating, ventilating and air
conditioning in the capacity set forth in the Work Letter. Any additional
utility services required by Tenant shall be procured by Tenant at its sole cost
and expense and shall comply with all regulations and limitations as may be
prescribed by any applicable policies, regulations or guidelines adopted by any
federal, state or local governmental or quasi-governmental entities or utility
suppliers. Landlord may establish in the Premises such measures as are required
by laws, ordinances, rules or regulations or as it deems necessary or
appropriate to conserve energy, including automatic switching of lights and/or
more efficient forms of lighting. Tenant shall have access to the Building and
all of the foregoing services 24 hours a day, 7 days a week.

               8.3. Interruption or Unavailability of Services. Rent shall not
abate, no constructive or other eviction shall be construed to have occurred,
Tenant shall not be relieved from any of its obligations under this Lease, and
Landlord shall not be in default hereunder or liable for any damages directly or
indirectly resulting from, the failure of Landlord to furnish, or delay in
furnishing, any maintenance or services under this Article 8 as a result of
repairs, alterations, improvements or any circumstances beyond Landlord's
reasonable control. Landlord shall use reasonable diligence to remedy any
failure or interruption in the furnishing of such maintenance or services.
Notwithstanding anything set forth in this Lease to the contrary, if such
interruption or interference with access to the Premises, or unavailability of
services continues for more than thirty (30) consecutive days and such
interruption or unavailability prevents Tenant from using the Premises, then
commencing upon the expiration of such thirty (30) day period, Rent shall abate
until beneficial use of the Premises is restored.

               8.4. Tenant's Payment of Utilities. Commencing on the
Commencement Date and continuing throughout the Term, Tenant shall pay directly
to the utility providing such service, as the same become due, all charges for
water, gas, electricity, steam, telephone, sewer, waste pick-up and any other
utilities, materials or services furnished to the Premises and/or used by Tenant
on or about the Premises during the Term, including, without limitation, (i)
meter, use, connection, hook-up and/or standby fees (including any connection or
hook-up fees which relate to making the existing electrical, steam, gas, and
water service available to the Premises as of or following the Commencement
Date), and (ii) penalties for discontinued or interrupted service relating to
discontinuance and interruptions following the Commencement Date (except
penalties resulting from Landlord's acts or omissions).

        9. Maintenance of Premises. Except as set forth in the second sentence
of Section 8.1, Tenant shall, at all times during the Term, at Tenant's cost and
expense, keep the Premises in good condition and repair, except for ordinary
wear and tear and damage by casualty or condemnation. Tenant shall obtain at its
own cost janitorial supplies and services for the Premises (which services shall
at a minimum consist of vacuuming, emptying waste baskets and dusting at least
five days a week) so that the interior of the Premises shall be maintained in a
clean and sanitary order and condition as required by this Article 9. Except as
may be specifically set forth in this Lease (including the Work Letter),
Landlord has no obligation to alter, remodel, improve, repair, decorate or paint
the Premises, or any part thereof, or any obligation respecting the condition,
maintenance and repair of the Premises or any other portion of the Building.
Except as expressly set forth herein, Tenant hereby waives all rights, including
those provided in California Civil Code Section 1941 or any successor statute,
to make repairs which are Landlord's


                                       12


<PAGE>   16
obligation under this Lease at the expense of Landlord or to receive any setoff
or abatement of Rent or in lieu thereof to vacate the Premises or terminate this
Lease.

        10. Alterations to Premises.

               10.1. Landlord Consent; Procedure. Tenant shall not make or
permit to be made any Alterations without Landlord's prior consent, which
consent may be granted or withheld in Landlord's reasonable discretion; no
consent shall be required for non-structural Alterations which do not require a
building permit and which, in the aggregate per project, cost less than
$25,000.00 to construct. Any Alterations to which Landlord has consented shall
be made in accordance with procedures as then established by Landlord and the
provisions of this Article 10.

               10.2. General Requirements. All Alterations shall be made at
Tenant's cost and expense. Tenant shall be solely responsible for compliance
with applicable laws, ordinances, rules and regulations in connection with all
Alterations. Tenant shall be responsible for the cost of any additional
alterations required by applicable laws, ordinances, rules and regulations to be
made by Landlord to any portion of the Building as a result of Alterations.
Tenant shall promptly commence or cause the commencement of construction of all
Alterations and complete or cause completion of the same with due diligence as
soon as possible after commencement.

               10.3. Removal of Alterations. If required by Landlord at the time
Landlord provides consent to an Alteration, Tenant shall, prior to the
expiration of the Term or termination of this Lease, remove such Alteration at
Tenant's cost and expense and restore the Premises to the condition existing
prior to the installation of such Alteration. If Tenant fails so to do, then
Landlord may remove such Alteration and perform such restoration and Tenant
shall reimburse Landlord for Landlord's cost and expense incurred to perform
such removal and restoration (which obligation of Tenant shall survive the
expiration or earlier termination of this Lease). Tenant shall repair at its
cost and expense all damage to the Premises or the Building caused by the
removal of such Alteration. Subject to the foregoing provisions regarding
removal, all Alterations (including any above Building standard improvements to
the Premises) shall be Landlord's property and from and after the expiration or
earlier termination of this Lease shall remain on the Premises without
compensation to Tenant. Tenant's trade fixtures, furniture, equipment and other
personal property installed in the Premises ("Tenant's Property") shall at all
times be and remain Tenant's property. Tenant may remove Tenant's Property from
the Premises at any time, provided that Tenant repairs all damage caused by such
removal. Landlord shall have no lien or other interest in any item of Tenant's
Property.

        11. Liens. Tenant shall keep the Premises and the Building free from any
liens arising out of any work performed or obligations incurred by or for, or
materials furnished to, Tenant pursuant to this Lease or otherwise. Landlord
shall have the right to post and keep posted on the Premises any notices
required by law or which Landlord may deem to be proper for the protection of
Landlord, the Premises and the Building from such liens and to take any other
action at the expense of Tenant that Landlord deems necessary or appropriate to
prevent, remove or discharge such liens. Tenant shall protect, defend, indemnify
and hold Landlord harmless from and against any claim, demand, cause of action,
obligation, liability, loss, cost or expense (including reasonable attorneys'
fees) which may be asserted against or incurred by Landlord as a result of
Tenant's failure to comply with the foregoing obligation (which indemnity
obligation shall survive the expiration or earlier termination of this Lease).

        12. Damage or Destruction.

               12.1. Obligation to Repair. Except as otherwise provided in this
Article 12, if the


                                       13


<PAGE>   17
Premises, or any other portion of the Building necessary for Tenant's use and
occupancy of the Premises, are damaged or destroyed by fire or other casualty,
Landlord shall, within thirty (30) days after such event, notify Tenant of the
estimated time, in Landlord's reasonable judgment, required to repair such
damage or destruction. Unless Landlord terminates this Lease as set forth in
Section 12.2, then (i) Landlord shall proceed with all due diligence to repair
the Premises, and/or the portion of the Building necessary for Tenant's use and
occupancy of the Premises, to substantially the condition existing immediately
before such damage or destruction, as permitted by and subject to then
applicable laws, ordinances, rules and regulations; (ii) this Lease shall remain
in full force and effect; and (iii) Rent shall abate for such part of the
Premises rendered unusable by Tenant in the conduct of its business during the
time such part is so unusable, in the proportion that the Rentable Area
contained in the unusable part of the Premises bears to the total Rentable Area
of the Premises.

               12.2. Termination Rights. If Landlord determines that the
necessary repairs cannot be completed within two hundred seventy (270) days
after the date of damage or destruction, or if such damage or destruction arises
from causes not covered by Landlord's insurance policy required to be carried
hereunder, Landlord may elect, in its notice to Tenant pursuant to Section 12.1,
to (i) terminate this Lease or (ii) repair the Premises pursuant to the
applicable provisions of Section 12.1 above. If Landlord terminates this Lease,
then this Lease shall terminate as of the date of occurrence of the damage or
destruction. If Landlord determines that the necessary repairs cannot be
completed within two hundred seventy (270) days after the date of damage but
Landlord does not elect terminate the Lease pursuant to this Section 12.2,
Tenant shall have the right to terminate the Lease upon written notice to Tenant
to be delivered within ten (10) days of receipt by Tenant of Landlord's notice
of Landlord's determination that such damage or destruction cannot be completed
within two hundred seventy (270) days. Notwithstanding anything to the contrary
herein, Landlord shall not have the right to terminate the Lease if (i) that
portion of the damage or destruction arising from causes covered by Landlord's
insurance policy required to be carried hereunder may be completed within two
hundred seventy (270) after the date of damage or destruction; (ii) the cost of
that portion of the damage or destruction arising from causes not covered by
Landlord's insurance policy required to be carried hereunder is less than five
percent (5%) of the replacement cost of the Building; or (iii) Tenant deposits
with Landlord prior to the commencement of any restoration work the full cost of
the uninsured portion of the costs required to repair the Building.


               12.3. Cost of Repairs. Landlord shall pay the cost for repair of
the Building and all improvements in the Premises, other than any Alterations.
If Tenant elects to repair any damaged Alterations, Tenant may pay the costs
therfor (but Landlord shall make available to Tenant for such purpose any
insurance proceeds received by Landlord for such purpose under Landlord's
insurance policy then in force). Tenant may also replace or repair, at Tenant's
cost and expense, Tenant's movable furniture, equipment, trade fixtures and
other personal property in the Premises which Tenant shall be responsible for
insuring during the Term of this Lease.

               12.4. Damage at End of Term. Notwithstanding anything to the
contrary contained in this Article 12, if the Premises, or any other portion
thereof or of the Building, are materially damaged or destroyed by fire or other
casualty within the last seven (7) months of the Term, then Landlord shall have
the right, in its sole discretion, to terminate this Lease by notice to Tenant
given within ninety (90) days after the date of such event. Such termination
shall be effective on the date specified in Landlord's notice to Tenant, but in
no event later than the end of such 90-day period. For purposes hereof, the
Premises or other portion of the Building shall be deemed to be materially
damaged if such damage costs more than $2,000,000 to repair

               12.5. Waiver of Statutes. The respective rights and obligations
of Landlord and Tenant


                                       14


<PAGE>   18
in the event of any damage to or destruction of the Premises, or any other
portion of the Building, are governed exclusively by this Lease. Accordingly,
Tenant hereby waives the provisions of any law to the contrary, including
California Civil Code Sections 1932(2) and 1933(4) providing for the termination
of a lease upon destruction of the leased property.

        13. Eminent Domain.

               13.1. Effect of Taking. Except as otherwise provided in this
Article 13, if all or any part of the Premises is taken as a result of the
exercise of the power of eminent domain or condemned for any public or
quasi-public purpose, or if any transfer is made in avoidance of such exercise
of the power of eminent domain (collectively, "taken" or a "taking"), this Lease
shall terminate as to the part of the Premises so taken as of the effective date
of such taking. On a taking of a portion of the Premises, Tenant shall have the
right to terminate this Lease by notice to Landlord within thirty (30) days
after the effective date of such taking, if the portion of the Premises taken is
of such extent and nature so as to materially impair Tenant's business use of
the balance of the Premises, as reasonably determined by Tenant. Such
termination shall be operative as of the effective date of the taking. Landlord
may terminate this Lease on a taking of any material portion of the Building if
Landlord reasonably determines that such taking is of such extent and nature as
to render the operation of the remaining Building economically infeasible or to
require a substantial alteration or reconstruction of such remaining portion.
Landlord shall elect such termination by notice to Tenant given within thirty
(30) days after the effective date of such taking, and such termination shall be
operative as of the effective date of such taking. Upon a taking of the Premises
which does not result in a termination of this Lease, the Base Rent shall
thereafter be reduced as of the effective date of such taking in the proportion
that the rentable area of the Premises so taken bears to the total rentable area
of the Premises.

               13.2. Condemnation Proceeds. Except as hereinafter provided, in
the event of any taking, Landlord shall have the right to all compensation,
damages, income, rent or awards made with respect thereto (collectively an
"award"), including any award for the value of the leasehold estate created by
this Lease. No award to Landlord shall be apportioned and, subject to Tenant's
rights hereinafter specified, Tenant hereby assigns to Landlord any right of
Tenant in any award made for any taking. Notwithstanding the foregoing, Tenant
may seek to recover, at its cost and expense, as a separate claim, any damages
or awards payable on a taking of the Premises to compensate for the unamortized
cost paid by Tenant for the alterations, additions or improvements, if any, made
by or on behalf of Tenant during the initial improvement of the Premises
pursuant to the Work Letter and for any Alterations, or for Tenant's personal
property taken, or for interference with or interruption of Tenant's business
(including goodwill), or for Tenant's removal and relocation expenses.

               13.3. Restoration of Premises. On a taking of the Premises which
does not result in a termination of this Lease, Landlord and Tenant shall
restore the Premises as nearly as possible to the condition they were in prior
to the taking in accordance with the applicable provisions and allocation of
responsibility for repair and restoration of the Premises on damage or
destruction pursuant to Article 12 above, and both parties shall use any awards
received by such party attributable to the Premises for such purpose.

               13.4. Tenant Waiver. The rights and obligations of Landlord and
Tenant on any taking of the Premises or any other portion of the Building are
governed exclusively by this Lease. Accordingly, Tenant hereby waives the
provisions of any law to the contrary, including California Code of Civil
Procedure Sections 1265.120 and 1265.130, or any similar successor statute.

        14. Insurance.


                                       15


<PAGE>   19
               14.1. Liability Insurance. Landlord, with respect to the
Building, and Tenant, at its cost and expense with respect to the Premises,
shall each maintain or cause to be maintained, from the Lease Date and
throughout the Term, a policy or policies of Commercial General Liability
insurance with limits of liability not less than Two Million Dollars
($2,000,000.00) per occurrence and in the aggregate. Each policy shall contain
coverage for blanket contractual liability, personal injury liability, and
premises operations, coverage deleting liquor liability exclusions and, as to
Tenant's insurance, fire legal liability. Landlord shall have the right to
approve the deductible under each policy of Tenant's liability insurance, such
approval not to be unreasonably withheld.

               14.2. Form of Policies. All insurance required by this Article 14
shall be issued on an occurrence basis by solvent companies qualified to do
business in the State of California, with a Best's rating of at least A and a
financial size category of at least Class X, as set forth in the most recent
edition of Best's. Any insurance required under this Article 14 may be
maintained under a "blanket policy", insuring other parties and other locations,
so long as the amount and coverage required to be provided hereunder is not
thereby diminished. Tenant shall provide Landlord a copy of each policy of
insurance or a certificate thereof certifying that the policies contain the
provisions required hereunder. Tenant shall deliver such policies or
certificates to Landlord within (30) days after the Lease Date, but in no event
less than ten (10) business days prior to the Commencement Date or such earlier
date as Tenant or Tenant's contractors, agents, licensees, invitees or employees
first enter the Premises and, upon renewal, not less than thirty (30) days prior
to the expiration of such coverage. All evidence of insurance provided to
Landlord shall provide (i) that Landlord, Landlord's managing agent and any
other person requested by Landlord who has an insurable interest, is designated
as an additional insured without limitation as to coverage afforded under such
policy; (ii) for severability of interests or that the acts or omissions of one
of the insureds or additional insureds shall not reduce or affect coverage
available to any other insured or additional insured; (iii) that the insurer
agrees not to cancel or reduce the coverage under the policy without at least
thirty (30) days prior written notice to all additional insureds; (iv) that the
aggregate liability applies solely to the Premises and the remainder of the
Building; and (v) that Tenant's insurance is primary and noncontributing with
any insurance carried by Landlord.

and expense, shall maintain Workers' Compensation insurance as required by law
and employer's liability insurance in an amount of not less than Five Hundred
Thousand Dollars ($500,000).

               14.4. Additional Tenant Insurance. Tenant, at its sole cost and
expense, shall maintain such other insurance as Landlord may reasonably require
from time to time, but in no event may Landlord require any other insurance
which is (i) not then being required of comparable tenants leasing comparable
amounts of space in comparable buildings in the vicinity of the Building or (ii)
not then available at commercially reasonable rates.

               14.5. Landlord's Casualty Insurance. Landlord shall, during the
Term of this Lease, procure and maintain in full force and effect, a policy or
policies of "all risk" insurance covering the Building and the permanent tenant
improvements in the Premises (including Alterations of which Landlord has
notice), with standard extended coverage, vandalism, malicious mischief and
sprinkler leakage endorsements. The amount and scope of coverage of Landlord's
insurance hereunder shall be determined by Landlord from time to time in its
reasonable discretion based on prudent risk management practices for buildings
comparable to the Building (but shall not be less than 90% of full replacement
value of the Building and Tenant's permanent tenant improvements in the Premises
(including Alterations of which Landlord has notice), and shall be subject to
such deductible amounts as Landlord may reasonably elect based on prudent risk
management practices for buildings comparable to the Building).

        15. Waiver of Subrogation Rights. Notwithstanding anything to the
contrary contained in this Lease, Landlord and Tenant, for themselves and their
respective insurers, agree to and do hereby release each other and their
respective employees, contractors, agents, assignees and subtenants, of and from
any and all claims, demands, actions and causes of action that each may have or
claim to have against the other for loss or damage to property, both real and
personal, notwithstanding that any such loss or damage may be due to or result
from the negligence of either of the parties hereto or their respective
employees, contractors, agents, assignees and subtenant, to the extent such
damage is due to a risk that is required to be insured hereunder. Each party
shall, to the extent such insurance endorsement is lawfully available at
commercially reasonable rates, obtain or cause to be obtained, for the benefit
of the other party, a waiver of any right of subrogation which the insurer of

<PAGE>   21
Building or the other public areas in the Building (except for such loss, damage
or injury for which Tenant is obligated to indemnify Landlord under Section
16.2).

        17. Assignment and Subletting.

               17.1. Compliance Required. Tenant shall not, directly or
indirectly, voluntary or by operation of law, sell, assign or otherwise transfer
this Lease, or any interest herein (collectively, "assign" or "assignment"), or
sublet the Premises, or any part thereof, or permit the occupancy of the
Premises by any person other than Tenant (collectively, "sublease" or
"subletting", the assignee or sublessee under an assignment or sublease being
referred to as a "transferee"), without Landlord's prior consent given or
withheld in accordance with the express standards and conditions of this Article
17 and compliance with the other provisions of this Article 17. Any assignment
or subletting made in violation of this Article 17 shall be void. Tenant
acknowledges and agrees that the limitations on Tenant's right to sublet or
assign which are set forth in this Article 17 are reasonable and, in particular,
that the express standards and conditions upon Tenant's right to assign or
sublet which are set forth in this Article 17 are reasonable as of the Lease
Date.

               17.2. Request by Tenant; Landlord Response. If Tenant desires to
effect an assignment or sublease, Tenant shall submit to Landlord a request for
consent together with the identity of the parties to the transaction, the nature
of the transferee's proposed business use for the Premises, the proposed
documentation for and terms of the transaction, and all other information
reasonably requested by Landlord concerning the proposed transaction and the
parties involved therein, including certified financial information, credit
reports, the business background and references regarding the transferee, and an
opportunity to meet and interview the transferee. Within fifteen (15) days after
the later of such interview or the receipt of all such information required by
Landlord, or within fifteen (15) days after the date of Tenant's request to
Landlord if Landlord does not request additional information or an interview,
Landlord shall have the right, by notice to Tenant, to: (i) consent to the
assignment or sublease, subject to the terms of this Article 17; or (ii) decline
to consent to the assignment or sublease. Provided that the request for consent
and documentation is marked "LANDLORD'S RESPONSE IS REQUIRED WITHIN 15 DAYS OF
RECEIPT OF THIS NOTICE PURSUANT TO THE TERMS OF THE LEASE BETWEEN LANDLORD AND
THE UNDERSIGNED" and the envelope containing the request is marked "PRIORITY",
Landlord's failure to respond within the fifteen-day period described in the
foregoing sentence shall constitute Landlord's consent to the proposed sublease
or assignment.

               17.3. Conditions for Landlord Approval. Landlord shall not
unreasonably withhold its consent to a proposed subletting or assignment by
Tenant. Without limiting the grounds on which it may be reasonable for Landlord
to withhold its consent to an assignment or sublease, Tenant agrees that
Landlord would be acting reasonably in withholding its consent in the following
instances: (i) if Tenant is in default under this Lease after applicable notice
and cure periods; (ii) if the transferee is a governmental or quasi-governmental
agency, foreign or domestic; (iii) if, in Landlord's sole but reasonably
judgment, the transferee's business, use and/or occupancy of the Premises would
(A) violate any of the terms of this Lease , or (B) require any Alterations
which would reduce the value of the existing leasehold improvements in the
Premises; (iv) if the financial condition of the transferee does not meet the
requirements that would be applied by Landlord for a tenant in the Building
under leases with comparable terms. If Landlord consents to an assignment or
sublease, the terms of such assignment or sublease transaction shall not be
modified without Landlord's prior written consent pursuant to this Article 17.
Landlord's consent to an assignment or subletting shall not be deemed consent to
any subsequent assignment or subletting.

               17.4. Costs and Expenses. As a condition to the effectiveness of
any assignment or


                                       18


<PAGE>   22
subletting under this Article 17, Tenant shall pay to Landlord all reasonable
costs and expenses, including reasonable attorneys' fees and disbursements,
incurred by Landlord in evaluating Tenant's requests for assignment or sublease,
whether or not Landlord consents to an assignment or sublease. Tenant shall pay
the processing fee with Tenant's request for Landlord's consent under Section
17.2.

               17.5. Payment of Excess Rent and Other Consideration. Tenant
shall also pay to Landlord, promptly upon Tenant's receipt thereof, fifty
percent (50%) of any and all rent, sums or other consideration, howsoever
denominated, realized by Tenant in connection with any assignment or sublease
transaction in excess of the Base Rent and Escalation Rent payable hereunder
(prorated to reflect the Rent allocable to the portion of the Premises if a
sublease), after first deducting, (i) in the case of an assignment, the
unamortized reasonable cost of Alterations paid for by Tenant and reasonable
attorney's fee and real estate commissions paid by Tenant in connection with
such assignment and, (ii) in the case of a sublease, the reasonable cost of
Alterations made to the Premises at Tenant's cost to effect the sublease, and
the reasonable attorney's fees and the amount of any real estate commissions
paid by Tenant, both amortized over the term of the sublease.

               17.6. Assumption of Obligations; Further Restrictions on
Subletting. Each assignee shall, concurrently with any assignment, assume all
obligations of Tenant under this Lease. Each sublease shall be made subject to
this Lease and all of the terms, covenants and conditions contained herein; and
the surrender of this Lease by Tenant, or a mutual cancellation thereof, or the
termination of this Lease in accordance with its terms, shall not work a merger
and shall, at the option of Landlord, terminate all or any existing subleases or
operate as an assignment to Landlord of any or all such subleases. No sublessee
of a sublessee shall have the right further to sublet more than one additional
time. Any assignment by a sublessee of its sublease shall be subject to
Landlord's prior consent in the same manner as a sublease by Tenant. No
sublease, once consented to by Landlord, shall be modified without Landlord's
prior consent. No assignment or sublease shall be binding on Landlord unless the
transferee delivers to Landlord a fully executed counterpart of the assignment
or sublease which contains the assumption by the assignee, or recognition by the
sublessee, of the provisions of this Section 17.6, in form and substance
satisfactory to Landlord, but the failure or refusal of a transferee to deliver
such instrument shall not release or discharge such transferee from the
provisions and obligations of this Section 17.6, but such failure shall
constitute a breach under this Lease by Tenant.

               17.7. No Release. No assignment or sublease shall release Tenant
from its obligations under this Lease, whether arising before or after the
assignment or sublease. The acceptance of Rent by Landlord from any other person
shall not be deemed a waiver by Landlord of any provision of this Article 17. On
a default by any assignee of Tenant in the performance of any of the terms,
covenants or conditions of this Lease, Landlord may proceed directly against
Tenant without the necessity of commencing or exhausting remedies against such
assignee. No consent by Landlord to any further assignments or sublettings of
this Lease, or any modification, amendment or termination of this Lease, or
extension, waiver or modification of payment or any other obligations under this
Lease, or any other action by Landlord with respect to any assignee or
sublessee, or the insolvency, or bankruptcy or default of any such assignee or
sublessee, shall affect the continuing liability of Tenant for its obligations
under this Lease and Tenant waives any defense arising out of or based thereon,
including any suretyship defense of exoneration. Landlord shall have no
obligation to notify Tenant or obtain Tenant's consent with respect to any of
the foregoing matters.

               17.8. No Encumbrance. Notwithstanding anything to the contrary
contained in this Article 17, Tenant shall have no right to encumber, pledge,
hypothecate or otherwise transfer this Lease, or any of Tenant's interest or
rights hereunder, as security for any obligation or liability of Tenant without
Landlord's prior written consent.

               17.9 Assignment or Sublease to Related Entity. As long as
Critical Path or a Related Entity (as defined herein) is the Tenant in
possession of the Premises and no default then exists beyond applicable notice
and cure periods, Tenant shall have the right, subject to the terms and
conditions set forth in this Sections 17.9 but not Section 17.5, without the
consent of Landlord, but without in any way releasing Critical Path from any of
its obligations under this Lease, to (a) assign its interest in this Lease to a
corporation or other entity which shall control, be under the control of, or be
under common control with Critical Path (the term "control" as used herein shall
be deemed to mean ownership of more than fifty percent (50%) of the outstanding
voting stock of a corporation, or other majority equity and control interest if
Tenant is not a corporation) or successor entity related to Tenant by merger,
consolidation or reorganization or a purchaser of substantially all of Tenant's
assets (any such entity being a "Related Entity"), or (b) sublease all or any
portion of the Premises to a Related Entity, so long as such sublease does not
result in the demising of any space in the Premises. Any assignment or sublease
to a Related Entity pursuant to this Section 17.9 shall be subject to the
following conditions: (i) the principal purpose of such assignment or sublease
is not the acquisition of Tenant?s interest in this Lease (except if such
assignment or sublease is made to a Related Entity and is made for a valid
intra-corporate business purpose and is not made to circumvent the provisions of
this Article 17), (ii) any such assignee shall have a net worth and annual
income and cash flow, determined in accordance with generally accepted
accounting principles, consistently applied, after giving effect to such
assignment, in amounts necessary to perform its duties, obligations and
liabilities hereunder, as reasonably determined by Landlord, (iii) such
assignment or sublease shall be subject to the terms of this Lease, including
the provisions of Sections 17.6 and 17.7, and (iv) such Related Entity shall
have executed all documents reasonably requested by Landlord to memorialize the
foregoing. Tenant shall, within ten (10) business days after execution thereof,
deliver to Landlord (A) a duplicate original instrument of assignment in form
and substance reasonably satisfactory to Landlord, duly executed by Tenant, (B)
if applicable, evidence reasonably satisfactory to Landlord establishing
compliance by the assignee with the net worth, income and cash flow requirements
of clause (b)(ii) above, (C) an instrument in form and substance reasonably
satisfactory to Landlord, duly executed by the assignee, in which such assignee
shall assume observance and performance of, and agree to be personally bound by,
all of the terms, covenants and conditions of this Lease on Tenant?s part to be
observed and performed or (D) a duplicate original sublease in form and
substance reasonably satisfactory to Landlord, duly executed by Tenant and
subtenant.

        18. Rules and Regulations. Tenant shall observe and comply, and shall
cause its sublessees, employees, agents, contractors, licensees and invitees to
observe and comply, with the Rules and Regulations of the Building, a copy of
which are attached to this Lease as Exhibit D, and, after notice thereof, with
all modifications and additions thereto from time to time promulgated in writing
by Landlord. Landlord shall not be responsible to Tenant, or Tenant's
sublessees, employees, agents, contractors, licensees or invitees, for
noncompliance with any Rules and Regulations of the Building by any other
tenant, sublessee, employee, agent, contractor, licensee, invitee or other
occupant of the Building. Tenant shall not be required to comply with any new
rule or regulation unless the same applies non-discriminatorily to all occupants
of the Building, does not unreasonably interfere with Tenant's use of the
Premises or Tenant's parking rights and does not materially increase the
obligations or decrease the rights of Tenant under the Lease

        19. Entry of Premises by Landlord.

               19.1. Right to Enter. Upon 24 hours advance notice to Tenant
(except in emergencies or in order to provide regularly scheduled or other
routine Building standard services or additional services requested by Tenant,
or post notices of nonresponsibility or other notices permitted or required by
law when no such notice shall be required), Landlord and its authorized agents,
employees, and contractors


                                       20


<PAGE>   24
may enter the Premises at reasonable hours to: (i) inspect the same; (ii)
determine Tenant's compliance with its obligations hereunder; (iii) exhibit the
same to prospective purchasers, lenders or tenants; (iv) supply any services to
be provided by Landlord hereunder; (v) post notices of nonresponsibility or
other notices permitted or required by law; (vi) make repairs, improvements or
alterations, or perform maintenance in or to, the Premises or any other portion
of the Building, including Building systems; and (vii) perform such other
functions as Landlord deems reasonably necessary or desirable. Landlord may also
grant access to the Premises to government or utility representatives and bring
and use on or about the Premises such equipment as reasonably necessary to
accomplish the purposes of Landlord's entry. Landlord shall use reasonable good
faith efforts to effect all entries and perform all work hereunder in such
manner as to minimize interference with Tenant's use and occupancy of the
Premises. Landlord shall have and retain keys with which to unlock all of the
doors in or to the Premises (excluding Tenant's vaults, safes and similar secure
areas designated in writing by Tenant in advance), and Landlord shall have the
right to use any and all means which Landlord may deem proper in an emergency in
order to obtain entry to the Premises, including secure areas. Any entry shall
comply with Tenant's reasonable security measures.

               19.2. Tenant Waiver of Claims. Except for damages to persons or
property caused by the gross negligence or willful misconduct of Landlord,
Tenant waives any claim for damages for any inconvenience to or interference
with Tenant's business, or any loss of occupancy or quiet enjoyment of the
Premises, or any other loss, occasioned by any entry effected or work performed
under this Article 19, and Tenant shall not be entitled to any abatement of Rent
by reason of the exercise of any such right of entry or performance of such
work. No entry to the Premises by Landlord or anyone acting under Landlord shall
constitute a forcible or unlawful entry into, or a detainer of, the Premises or
an eviction, actual or constructive, of Tenant from the Premises, or any portion
thereof.

        20. Default and Remedies.

               20.1. Events of Default. The occurrence of any of the following
events shall constitute a default by Tenant under this Lease:

                      a. Nonpayment of Rent. Failure to pay any Rent when due.

                      b. Unpermitted Assignment. An assignment or sublease made
in contravention of any of the provisions of Article 17 above.

                      c. Abandonment. Abandonment of the Premises for a
continuous period in excess of five (5) business days. For purposes hereof,
"abandonment" shall have the meaning provided under California law.

                      d. Other Obligations. Failure to perform or fulfill any
other obligation, covenant, condition or agreement under this Lease.

                      e. Bankruptcy and Insolvency. A general assignment by
Tenant for the benefit of creditors, any action or proceeding commenced by
Tenant under any insolvency or bankruptcy act or under any other statute or
regulation for protection from creditors, or any such action commenced against
Tenant and not discharged within thirty (30) days after the date of
commencement; the employment or appointment of a receiver or trustee to take
possession of all or substantially all of Tenant's assets or the Premises which
is not discharged within thirty (30) days; the attachment, execution or other
judicial seizure of all or substantially all of Tenant's assets or the Premises,
if such attachment or other seizure remains undismissed or undischarged for a
period of thirty (30) days after the levy thereof; the admission


                                       21


<PAGE>   25
by Tenant in writing of its inability to pay its debts as they become due; or
the filing by Tenant of a petition seeking any reorganization, arrangement,
composition, readjustment, liquidation, dissolution or similar relief under any
present or future statute, law or regulation, the filing by Tenant of an answer
admitting or failing timely to contest a material allegation of a petition filed
against Tenant in any such proceeding or, if within thirty (30) days after the
commencement of any such proceeding against Tenant, such proceeding is not
dismissed. For purposes of this Section 20.1(e), "Tenant" means Tenant and any
partner of Tenant, if Tenant is a partnership, or any person or entity
comprising Tenant, if Tenant is comprised of more than one person or entity, or
any guarantor of Tenant's obligations, or any of them, under this Lease.

                      f. 530 Folsom Street. If, at any time that Landlord is
also the owner of the premises leased by Tenant under that certain Office Lease
of even date herewith for premises commonly known as 530 Folsom Street, San
Francisco (the "Folsom Lease"), Tenant is in default under the Folsom Lease,
beyond any applicable notice and cure period.

               20.2. Notice to Tenant. Upon the occurrence of any default,
Landlord shall give Tenant notice thereof. If a time period is specified below
for cure of such default, then Tenant may cure such default within such time
period.

                      a. Nonpayment of Rent. For failure to pay Rent, within
five (5) days after Landlord's notice, unless Tenant has failed more than two
(2) times during any calendar year to timely pay any Rent, in which event no
cure period shall apply.

                      b. Other Obligations. For failure to perform any
obligation, covenant, condition or agreement under this Lease (other than
nonpayment of Rent or Tenant's abandonment of the Premises) within ten (10) days
after Landlord's notice or, if the failure is of a nature requiring more than 10
days to cure, then an additional forty five (45) days after the expiration of
such 10-day period, but only if Tenant commences cure within such 10-day period
and thereafter diligently pursues such cure to completion within such additional
45-day period. If Tenant has failed to perform any such obligation, covenant,
condition or agreement more than two (2) times during any calendar year and
notice of such event of default has been given by Landlord in each instance,
then no cure period shall apply.

                      c. Assignment/Sublease. For an assignment or subletting in
violation of Article 17, within ten (10) days after Landlord's notice.

                      d. No Cure Period. No cure period shall apply for any
other event of default specified in Section 20.1.

               20.3. Remedies Upon Occurrence of Default. On the occurrence of a
default which Tenant fails to cure after notice and expiration of the time
period for cure, if any, specified in Section 20.2 above, Landlord shall have
the right either (i) to terminate this Lease and recover possession of the
Premises, or (ii) to continue this Lease in effect and enforce all Landlord's
rights and remedies under California Civil Code Section 1951.4 (by which
Landlord may recover Rent as it becomes due, subject to Tenant's right to assign
pursuant to Article 17). Landlord may store any property of Tenant located in
the Premises at Tenant's expense or otherwise dispose of such property in the
manner provided by law. If Landlord does not terminate this Lease, Tenant shall
in addition to continuing to pay all Rent when due, also pay Landlord's costs of
attempting to relet the Premises, any repairs and alterations necessary to
prepare the Premises for such reletting, and brokerage commissions and
attorneys' fees incurred in connection therewith, less the rents, if any,
actually received from such reletting. Notwithstanding Landlord's election to
continue this Lease in effect, Landlord may at any time thereafter


                                       22


<PAGE>   26
terminate this Lease pursuant to this Section 20.3.

               20.4. Damages Upon Termination. If and when Landlord terminates
this Lease pursuant to Section 20.3, Landlord may exercise all its rights and
remedies available under California Civil Code Section 1951.2, including the
right to recover from Tenant the worth at the time of award of the amount by
which the unpaid Rent for the balance of the Term after the time of award
exceeds the amount of such Rent loss that the Tenant proves could have been
reasonably avoided. As used herein and in Civil Code Section 1951.2, "time of
award" means either the date upon which Tenant pays to Landlord the amount
recoverable by Landlord, or the date of entry of any determination, order or
judgment of any court or other legally constituted body determining the amount
recoverable, whichever occurs first.

               20.5. Computation of Certain Rent for Purposes of Default. For
purposes of computing unpaid Rent pursuant to Section 20.4 above, Escalation
Rent for the balance of the Term shall be determined by averaging the amount
paid by Tenant as Escalation Rent for the calendar year prior to the year in
which the default occurred (or, if the prior year is the Base Year or such
default occurs during the Base Year, Escalation Rent shall be based on
Landlord's operating budget for the Building for the Base Year), increasing such
average amount for each calendar year (or portion thereof) remaining in the
balance of the Term at a per annum compounded rate equal to the mean average
rate of increase for the preceding five (5) calendar years in the United States
Department of Labor, Bureau of Labor Statistics, Consumer Price Index (All Urban
Consumers, All Items, 1982-1984 = 100) for the Metropolitan Area of which San
Francisco, California, is a part, and adding together the resulting amounts. If
such Index is discontinued or revised, such computation shall be made by
reference to the index designated as the successor or substitute index by the
United States Department of Labor, Bureau of Labor Statistics, or its successor
agency, and if none is designated, by a comparable index as determined by
Landlord in its sole discretion, which would likely achieve a comparable result
to that achieved by the use of the Consumer Price Index. If the base year of the
Consumer Price Index is changed, then the conversion factor specified by the
Bureau, or successor agency, shall be utilized to determine the Consumer Price
Index.


               20.6. Right to Cure Defaults. If Tenant fails to pay Rent (other
than Base Rent and Escalation Rent) required to be paid by it hereunder, or
fails to perform any other obligation under this Lease, and Tenant fails to cure
such default within the applicable cure period, if any, specified in Section
20.2 above, then Landlord may, without waiving any of Landlord's rights in
connection therewith or releasing Tenant from any of its obligations or such
default, make any such payment or perform such other obligation on behalf of
Tenant. All payments so made by Landlord, and all costs and expenses incurred by
Landlord to perform such obligations, shall be due and payable by Tenant as Rent
immediately upon receipt of Landlord's demand therefor. If Landlord fails to
make repairs to the Premises or perform any other obligations under this Lease
which Landlord is required to make pursuant to the terms of this Lease within
fifteen (15) days after written notice from Tenant (provided Landlord shall have
a longer time if reasonably necessary if Landlord commences cure within such
fifteen (15) day period and diligently prosecutes such cure to completion) and
such failure to repair materially and adversely affect Tenant's use of the
Premises, then Tenant shall give Landlord an additional three (3) business days
prior notice. If Landlord has not commenced repair within such three (3)
business day period, Tenant shall have the right to repair the Premises, and
Landlord shall reimburse Tenant for the reasonable cost thereof within thirty
(30) days after presentation of a reasonably detailed invoice demonstrating the
expenses incurred by Tenant. In the event Tenant makes such repairs, Tenant
shall be responsible for damages or injuries caused by Tenant or its employees,
contractors and subcontractors in making such repairs or any defect therein and
shall indemnify Landlord against any liability, cost or expense (including
attorneys' fees) arising out of such repair or any defect in the work performed.
If Landlord does not dispute Tenant's


                                       23


<PAGE>   27
right to reimbursement and fails to reimburse Tenant within such thirty (30) day
period, Tenant may deduct the cost of such cure from Rent.

               20.7. Remedies Cumulative. The rights and remedies of Landlord
under this Lease are cumulative and in addition to, and not in lieu of, any
other rights and remedies available to Landlord at law or in equity. Landlord's
pursuit of any such right or remedy shall not constitute a waiver or election of
remedies with respect to any other right or remedy.

        21. Subordination, Attornment and Nondisturbance.

               21.1. Subordination and Attornment. This Lease and all of
Tenant's rights hereunder shall be subordinate to any ground lease or underlying
lease, and the lien of any mortgage, deed of trust, or any other security
instrument now or hereafter affecting or encumbering the Building, or any part
thereof or interest therein, and to any and all advances made on the security
thereof or Landlord's interest therein, and to all renewals, modifications,
consolidations, replacements and extensions thereof (an "encumbrance", the
holder of the beneficial interest thereunder being referred to as an
"encumbrancer"). An encumbrancer may, however, subordinate its encumbrance to
this Lease, and if an encumbrancer so elects by notice to Tenant, this Lease
shall be deemed prior to such encumbrance. If any encumbrance to which this
Lease is subordinate is foreclosed, or a deed in lieu of foreclosure is given to
the encumbrancer thereunder, Tenant shall attorn to the purchaser at the
foreclosure sale or to the grantee under the deed in lieu of foreclosure; and if
any encumbrance consisting of a ground lease or underlying lease to which this
Lease is subordinate is terminated, Tenant shall attorn to the lessor thereof.
Tenant shall execute, acknowledge and deliver in the form reasonably requested
by Landlord or any encumbrancer, any documents required to evidence or
effectuate the subordination hereunder, or to make this Lease prior to the lien
of any encumbrance, or to evidence such attornment.

               21.2. Nondisturbance. If any encumbrance to which this Lease is
subordinate is foreclosed, or a deed in lieu of foreclosure is given to the
encumbrancer thereunder, or if any encumbrance consisting of a ground lease or
underlying lease to which this Lease is subordinate is terminated, this Lease
shall not terminate, and the rights and possession of Tenant under this Lease
shall not be disturbed if (i) no default by Tenant then exists under this Lease
(after expiration of applicable notice and cure periods); (ii) Tenant attorns to
the purchaser, grantee, or successor lessor as provided in Section 21.1 above
or, if requested, enters into a new lease for the balance of the Term upon the
same terms and provisions contained in this Lease; and (iii) Tenant enters into
a written agreement in a form reasonably acceptable to such encumbrancer with
respect to subordination, attornment and non-disturbance. Concurrent with the
execution of this Lease, Landlord shall use reasonable efforts to obtain a
non-disturbance agreement from the existing encumbrancer in a form reasonably
acceptable to Tenant. . If Tenant and the existing encumbrancer are not able to
agree upon a mutually acceptable non-disturbance agreement within fifteen (15)
days after the Lease Date, Tenant shall have the right to terminate the Lease
within three (3) business days after such fifteenth day.

        22. Sale or Transfer by Landlord; Lease Non-Recourse.

               22.1. Release of Landlord on Transfer. Landlord may at any time
transfer, in whole or in part, its right, title and interest under this Lease
and in the Building, or any portion thereof. If the original Landlord hereunder,
or any successor to such original Landlord, transfers (by sale, assignment or
otherwise) its right, title or interest in the Building and the transferee
assumes in writing all of landlord's obligations hereunder, all liabilities and
obligations of the original Landlord or such successor under this Lease accruing
after such transfer shall terminate, the original Landlord or such successor
shall automatically be released therefrom, and thereupon all such liabilities
and obligations shall be binding upon the new owner. Tenant shall attorn to each
such new owner.


                                       24


<PAGE>   28
               22.2. Lease Nonrecourse to Landlord. Landlord shall in no event
be personally liable under this Lease, and Tenant shall look solely to
Landlord's interest in the Building (including insurance and condemnation
proceeds, the Security Deposit and all proceeds thereof) of for recovery of any
damages for breach of this Lease by Landlord or on any judgment in connection
therewith. None of the persons or entities comprising or representing Landlord
(whether partners, shareholders, officers, directors, trustees, employees,
beneficiaries, agents or otherwise) shall ever be personally liable under this
Lease or liable for any such damages or judgment and Tenant shall have no right
to effect any levy of execution against any assets of such persons or entities
on account of any such liability or judgment. Any lien obtained by Tenant to
enforce any such judgment, and any levy of execution thereon, shall be subject
and subordinate to all encumbrances as specified in Article 21 above.

        23. Estoppel Certificate.

               23.1. Procedure and Content. From time to time, and within ten
(10) days after written notice by Landlord, Tenant shall execute, acknowledge,
and deliver to Landlord a certificate as specified by Landlord certifying: (i)
that this Lease is unmodified and in full force and effect (or, if there have
been modifications, that this Lease is in full force and effect, as modified,
and identifying each modification); (ii) the Commencement Date and Expiration
Date; (iii) that Tenant has accepted the Premises (or the reasons Tenant has not
accepted the Premises), and if Landlord has agreed to make any alterations or
improvements to the Premises, that Landlord has properly completed such
alterations or improvements (or the reasons why Landlord has not done so); (iv)
the amount of the Base Rent and current Escalation Rent, if any, and the date to
which such Rent has been paid; (v) that Tenant has not committed any event of
default, except as to any events of default specified in the certificate, and
whether there are any existing defenses against the enforcement of Tenant's
obligations under this Lease; (vi) that no default of Landlord is claimed by
Tenant, except as to any defaults specified in the certificate; and (vii) such
other matters as may be requested by Landlord.

               23.2. Effect of Certificate. Any such certificate may be relied
upon by any prospective purchaser of any part or interest in the Building or
encumbrancer (as defined in Section 21.1) and, at Landlord's request, Tenant
shall deliver such certificate to Landlord and/or to any such entity and shall
agree to such notice and cure provisions and such other matters as such entity
may reasonably require. In addition, at Landlord's request, Tenant shall provide
to Landlord for delivery to any such entity such information, including
financial information, that may reasonably be requested by any such entity. Any
such certificate shall constitute a waiver by Tenant of any claims Tenant may
have in contravention to the information contained in such certificate and
Tenant shall be estopped from asserting any such claim. If Tenant fails or
refuses to give a certificate hereunder within the time period herein specified,
then the information contained in such certificate as submitted by Landlord
shall be deemed correct for all purposes, but Landlord shall have the right to
treat such failure or refusal as a default by Tenant.

               23.2. Landlord's Estoppel If Tenant is required by an
unaffiliated third party to produce an estoppel certificate, Landlord shall,
within thirty (30) days after Tenant's request, execute and deliver to Tenant an
estoppel certificate in favor of Tenant and such other persons as Tenant shall
reasonably request, setting forth the following: (a) the Commencement Date and
the Expiration Date; (b) that this Lease is in full force and effect and has not
been assigned, modified, supplemented or amended (except by such writing as
shall be stated); (c) that all conditions under this Lease to be performed by
Tenant have, to Landlord's knowledge, been satisfied, or, in the alternative,
those claimed by Landlord to be unsatisfied; (d) that, to Landlord's knowledge,
no defenses or offsets exist against the enforcement of this Lease by Landlord,
or in the alternative, those claimed by Landlord; (e) that the amount of advance
Rent, if any (or none if such is the case), has been paid by Tenant; (f) the
date to which rent has been paid; and


                                       25


<PAGE>   29
(g) such other information as Tenant may reasonably request.

        24. No Light, Air, or View Easement. Nothing contained in this Lease
shall be deemed, either expressly or by implication, to create any easement for
light and air or access to any view. Any diminution or shutting off of light,
air or view to or from the Premises by any structure which now exists or which
may hereafter be erected, whether by Landlord or any other person, shall in no
way affect this Lease or Tenant's obligations hereunder, entitle Tenant to any
reduction of Rent, or impose any liability on Landlord.

        25. Holding Over. No holding over by Tenant shall operate to extend the
Term. If Tenant remains in possession of the Premises after expiration or
termination of this Lease, unless otherwise agreed by Landlord in writing, then
(i) Tenant shall become a tenant at sufferance upon all the applicable terms and
conditions of this Lease, except that Base Rent shall be increased to equal 150%
of the Base Rent then in effect; (ii) Tenant shall indemnify, defend, protect
and hold harmless Landlord, and any tenant to whom Landlord has leased all or
part of the Premises, from any and all liability, loss, damages, costs or
expense (including loss of Rent to Landlord or additional rent payable by such
tenant and reasonable attorneys' fees) suffered or incurred by either Landlord
or such tenant resulting from Tenant's failure timely to vacate the Premises;
and (iii) such holding over by Tenant shall constitute a default by Tenant.

        26. Security Deposit. If so specified in the Basic Lease Information,
Tenant shall deposit with Landlord the Security Deposit upon the execution of
this Lease by Tenant. The Security Deposit shall be held by Landlord as security
for the performance by Tenant of all its obligations under this Lease. If Tenant
fails to pay any Rent due hereunder, or otherwise commits a default (after
applicable notice and cure periods) with respect to any provision of this Lease,
Landlord may use, apply or retain all or any portion of the Security Deposit for
the payment of any such Rent or for the payment of any other amounts expended or
incurred by Landlord by reason of Tenant's default, or to compensate Landlord
for any loss or damage which Landlord may incur thereby (subject to the
provisions of California Civil Code Section 1950.7(c) and any similar or
successor statute providing that Landlord may claim from a security deposit only
those sums reasonably necessary to remedy defaults in the payment of Rent, to
repair damage caused by Tenant, or to clean the Premises). Exercise by Landlord
of its rights hereunder shall not constitute a waiver of, or relieve Tenant from
any liability for, any default. If Landlord so uses or applies all or any
portion of the Security Deposit, Tenant shall, within ten (10) days after demand
by Landlord, deposit cash with Landlord in an amount sufficient to restore the
Security Deposit to its full amount. If Tenant performs all of Tenant's
obligations hereunder, the Security Deposit, or so much thereof as has not
theretofore been applied by Landlord, shall be returned, without interest, to
Tenant (or, at Landlord's option, to the last assignee, if any, of Tenant's
interest under this Lease) within thirty (30) days after the later of (i) the
date of expiration or earlier termination of this Lease, or (ii) vacation of the
Premises by Tenant if the Premises has been left in the condition specified by
this Lease. Landlord's receipt and retention of the Security Deposit shall not
create any trust or fiduciary relationship between Landlord and Tenant and
Landlord need not keep the Security Deposit separate from its general accounts.
Subject to Section 22.1, upon termination of the original Landlord's (or any
successor owner's) interest in the Premises, the original Landlord (or such
successor) shall be released from further liability with respect to the Security
Deposit upon the original Landlord's (or such successor's) compliance with
California Civil Code Section 1950.7(d), or successor statute.

        27. Waiver. Failure of Landlord to declare a default by Tenant upon
occurrence thereof, or delay in taking any action in connection therewith, shall
not waive such default, but Landlord shall have the right to declare such
default at any time after its occurrence. To be effective, a waiver of any


                                       26


<PAGE>   30
provision of this Lease, or any default, shall be in writing and signed by the
waiving party. Any waiver hereunder shall not be deemed a waiver of subsequent
performance of any such provision or subsequent defaults. The subsequent
acceptance of Rent hereunder, or endorsement of any check by Landlord, shall not
be deemed to constitute an accord and satisfaction or a waiver of any preceding
default by Tenant, except as to the particular Rent so accepted, regardless of
Landlord's knowledge of the preceding default at the time of acceptance of the
Rent. No course of conduct between Landlord and Tenant, and no acceptance of the
keys to or possession of the Premises by Landlord before the Expiration Date
shall constitute a waiver of any provision of this Lease or of any default, or
operate as a surrender of this Lease.

        28. Notices and Consents; Tenant's Agent for Service. All notices,
approvals, consents, demands and other communications from one party to the
other given pursuant to this Lease shall be in writing and shall be made by
personal delivery, by use of a reputable overnight courier service or by deposit
in the United States mail, certified, registered or Express, postage prepaid and
return receipt requested. Notices shall be addressed if to Landlord, to
Landlord's Address, and if to Tenant, to Tenant's Address. Landlord and Tenant
may each change their respective Addresses from time to time by giving written
notice to the other of such change in accordance with the terms of this Article
28, at least ten (10) days before such change is to be effected. Any notice
given in accordance with this Article 28 shall be deemed to have been given (i)
on the date of personal delivery or (ii) on the earlier of the date of delivery
or attempted delivery (as shown by the return receipt or other delivery record)
if sent by courier service or mailed.

        29. Authority. Tenant represents and warrants that (i) Tenant is a duly
formed, authorized and existing corporation, (ii) Tenant is qualified to do
business in California, (iii) Tenant has the full right and authority to enter
into this Lease and to perform all of Tenant's obligations hereunder, and (iv)
each person signing on behalf of Tenant is authorized to do so. Tenant shall
deliver to Landlord, upon Landlord's request, such certificates, resolutions, or
other written assurances authorizing Tenant's execution and delivery of this
Lease, and such financial information regarding Tenant and its constituent
members, as requested by Landlord from time to time or at any time in order for
Landlord to assess Tenant's then authority and/or ability to meet its
obligations under this Lease. Landlord represents and warrants that (i) Landlord
is a duly formed, authorized and existing limited liability company (ii)
Landlord is qualified to do business in California, (iii) Landlord has the full
right and authority to enter into this Lease and to perform all of Landlord's
obligations hereunder, and (iv) each person signing on behalf of Landlord is
authorized to do so. Landlord shall deliver to Tenant, upon Landlord's request,
such certificates, resolutions, or other written assurances authorizing
Landlord's execution and delivery of this Lease.

        30. Automobile Parking. In consideration for the Base Rent paid
hereunder, Tenant shall have the right to occupy all of the parking stalls in
the Building during the Initial Term and any Extended Term at no additional
cost.

        31. Tenant to Furnish Financial Statements. In order to induce Landlord
to enter into this Lease, Tenant agrees that it shall promptly deliver to
Landlord, from time to time, upon Landlord's written request, publicly available
financial statements (including a balance sheet and statement of income and
expenses on an annualized basis) reflecting Tenant's then current financial
condition. Such statements shall be delivered to Landlord within fifteen (15)
days after Tenant's receipt of Landlord's request. Tenant represents and
warrants that all financial statements, records, and information furnished by
Tenant to Landlord in connection with this Lease are and shall be true, correct
and complete in all respects.

        32. Tenant's Signs. Tenant shall have the right to exclusive building
signage (including the exclusive right to utilize any billboard signage), but
Tenant shall not place on the Premises or on the


                                       27


<PAGE>   31
Building any exterior signs nor any interior signs that are visible from the
exterior of the Premises or Building without Landlord's prior consent, which
Landlord may withhold in its reasonable discretion. Landlord hereby consents to
the signage for the Building substantially similar to that on Tenant's existing
building located at 320 First Street in San Francisco. Tenant shall pay all
costs and expenses relating to any such sign approved by Landlord, including
without limitation, the cost of the installation and maintenance of the sign. On
the date of expiration or earlier termination of this Lease, Tenant, at its sole
cost and expense, shall remove all signs and repair any damage caused by such
removal. If Tenant elects to no longer utilize the billboard signage, Base Rent
payable to Landlord shall be reduced by $6,000 per month for the Initial Term
and any Extended Terms. Tenant shall have the right to terminate the rental of
the billboard signage upon one hundred eighty (180) days' written notice to
Landlord. If Tenant elects to terminate the rental of the billboard signage,
Landlord may rent the billboard signage to a third party, subject to the
reasonable approval of the Tenant. In no case shall Landlord lease any signage
on the Building to a competitor of Tenant.

        33. Miscellaneous.

               33.1. No Joint Venture. This Lease does not create any
partnership or joint venture or similar relationship between Landlord and
Tenant.

               33.2. Successors and Assigns. Subject to the provisions of
Article 17 regarding assignment, all of the provisions, terms, covenants and
conditions contained in this Lease shall bind, and inure to the benefit of, the
parties and their respective successors and assigns.

               33.3. Construction and Interpretation. The words "Landlord" and
"Tenant" include the plural as well as the singular. If there is more than one
person comprising Tenant, the obligations under this Lease imposed on Tenant are
joint and several. References to a party or parties refers to Landlord or
Tenant, or both, as the context may require. The captions preceding the
Articles, Sections and subsections of this Lease are inserted solely for
convenience of reference and shall have no effect upon, and shall be disregarded
in connection with, the construction and interpretation of this Lease. Use in
this Lease of the words "including", "such as", or words of similar import when
following a general matter, shall not be construed to limit such matter to the
enumerated items or matters whether or not language of nonlimitation (such as
"without limitation") is used with reference thereto. All provisions of this
Lease have been negotiated at arm's length between the parties and after advice
by counsel and other representatives chosen by each party and the parties are
fully informed with respect thereto. Therefore, this Lease shall not be
construed for or against either party by reason of the authorship or alleged
authorship of any provision hereof, or by reason of the status of the parties as
Landlord or Tenant, and the provisions of this Lease and the Exhibits hereto
shall be construed as a whole according to their common meaning in order to
effectuate the intent of the parties under the terms of this Lease.

               33.4. Severability. If any provision of this Lease, or the
application thereof to any person or circumstance, is determined to be illegal,
invalid or unenforceable, the remainder of this Lease, or its application to
persons or circumstances other than those as to which it is illegal, invalid or
unenforceable, shall not be affected thereby and shall remain in full force and
effect, unless enforcement of this Lease as so invalidated would be unreasonable
or grossly inequitable under the circumstances, or would frustrate the purposes
of this Lease.

               33.5. Entire Agreement; Amendments. This Lease, together with the
Exhibits hereto and any Addenda identified on the Basic Lease Information,
contains all the representations and the entire agreement between the parties
with respect to the subject matter hereof and any prior negotiations,
correspondence, memoranda, agreements, representations or warranties are
replaced in total by this


                                       28


<PAGE>   32
Lease, the Exhibits hereto and such Addenda. Neither Landlord nor Landlord's
agents have made any warranties or representations with respect to the Premises
or any other portion of the Building, except as expressly set forth in this
Lease. This Lease may be modified or amended only by an agreement in writing
signed by both parties.

               33.6. Governing Law. This Lease shall be governed by and
construed pursuant to the laws of the State of California.

               33.7. Litigation Expenses. If either party brings any action or
proceeding against the other (including any cross-complaint, counterclaim or
third party claim) to enforce or interpret this Lease or otherwise arising out
of this Lease, the prevailing party in such action or proceeding shall be
entitled to its costs and expenses of suit, including reasonable attorneys' fees
and accountants' fees.

               33.8. Standards of Performance and Approvals. Unless otherwise
provided in this Lease, (i) each party shall act in a reasonable manner in
exercising or undertaking its rights, duties and obligations under this Lease
and (ii) whenever approval, consent or satisfaction (collectively, an
"approval") is required of a party pursuant to this Lease or an Exhibit hereto,
such approval shall not be unreasonably withheld or delayed. Unless provision is
made for a specific time period, approval (or disapproval) shall be given within
thirty (30) days after receipt of the request for approval. Nothing contained in
this Lease shall, however, limit the right of a party to act or exercise its
business judgment in a subjective manner with respect to any matter as to which
it has been (A) specifically granted such right, (B) granted the right to act in
its sole discretion or sole judgment, or (C) granted the right to make a
subjective judgment hereunder, whether "objectively" reasonable under the
circumstances and any such exercise shall not be deemed inconsistent with any
covenant of good faith and fair dealing implied by law to be part of this Lease.
The parties have set forth in this Lease their entire understanding with respect
to the terms, covenants, conditions and standards pursuant to which their
obligations are to be judged and their performance measured, including the
provisions of Article 17 with respect to assignments and sublettings.

               33.9. Brokers. Landlord shall pay to Landlord's Broker and
Tenant's Broker, if any as specified in the Basic Lease Information of this
Lease, a commission in connection with such Brokers' negotiation of this Lease
pursuant to a separate agreement or agreements between Landlord and such
Brokers. Other than such Brokers, Landlord and Tenant each represent and warrant
to the other that no broker, agent, or finder has procured or was involved in
the negotiation of this Lease and no such broker, agent or finder is or may be
entitled to a commission or compensation in connection with this Lease. Landlord
and Tenant shall each indemnify, defend, protect and hold the other harmless
from and against any and all liability, loss, damages, claims, costs and
expenses (including reasonable attorneys' fees) resulting from claims that may
be asserted against the indemnified party in breach of the foregoing warranty
and representation.

               33.10. Memorandum of Lease. Either party shall, upon request of
the other, execute, acknowledge and deliver a short form memorandum of this
Lease (and any amendment hereto) in form suitable for recording. Tenant shall
have the right to record the memorandum and, if Tenant elects to do so, Tenant
shall pay all recording fees and transfer taxes in connection therewith. Upon
termination or expiration of the Lease, Tenant shall promptly execute and record
a quit claim deed or other instrument required to remove such memorandum from
the records of the San Francisco County Recorder's office.

               In no event shall this Lease be recorded by Tenant.

               33.11. Quiet Enjoyment. Upon paying the Rent and performing all
its obligations under


                                       29


<PAGE>   33
this Lease, Tenant may peacefully and quietly enjoy the Premises during the Term
as against all persons or entities claiming by or through Landlord, subject,
however, to the provisions of this Lease and any encumbrances as specified in
Article 21.

               33.12. Surrender of Premises. Upon the Expiration Date or earlier
termination of this Lease, Tenant shall quietly and peacefully surrender the
Premises to Landlord in the condition specified in Article 9 above. On or before
the Expiration Date or earlier termination of this Lease, Tenant shall remove
all of its personal property from the Premises and repair at its cost and
expense all damage to the Premises or Building caused by such removal. All
personal property of Tenant not removed hereunder shall be deemed, at Landlord's
option, to be abandoned by Tenant and Landlord may store such property in
Tenant's name at Tenant's expense and/or dispose of the same in any manner
permitted by law.

               33.13. Building Directory. INTENTIONALLY DELETED.

               33.14. Name of Building; Address. Tenant shall not use the name

correspondence, mail or deliveries made to or from the Premises, use the
official Building address specified from time to time by Landlord.

               33.15 Year 2000 Compliance. The Premises, Building and Land shall
meet all Year 2000 compliance requirements and the cost of such compliance shall
be at Landlord's sole expense.

               33.16. Exhibits. The Exhibits specified in the Basic Lease
Information are by this reference made a part hereof.

               33.17. Time of the Essence. Time is of the essence of this Lease
and of the performance of each of the provisions contained in this Lease.

               33.18. Reasonable Expenditures Any expenditure by a party
permitted or required under the Lease, for which such party demands
reimbursement from the other party, shall be limited to the fair market value of
the goods and services involved, shall be reasonably incurred, and shall be
substantiated by documentary evidence available for inspection and review by the
other party.

               IN WITNESS WHEREOF, the parties have executed this Lease as of
the Lease Date.

                          TENANT IMPROVEMENT AGREEMENT

        THIS TEN ANT IMPROVEMENT AGREEMENT ("Agreement") is made and entered
into by and between Landlord and Tenant as of the date of the Lease. This
Agreement shall be deemed a part of the Lease to which it is attached.
Capitalized terms which are used in this Agreement and defined in the Lease
shall have the meaning given in the Lease.

        1. General.

               1.1. The Parties' Respective Obligations. At Landlord's sole cost
and expense, in a good and workman like manner and in compliance with all
workplans and as-built plans approved by the City, Landlord shall construct the
Premises in "shell" condition which shall include only the work (the "Landlord's
Work") described on Schedule I attached to this Agreement and in those certain
plans prepared by Architecture Design Studio dated 10/5/99 (Delta 3 Set) Sheets
A0.1 through A10.2 and S-1 through S-21. At Tenant's sole cost and expense,
subject to the Construction Allowance described below, Landlord shall cause the
contractor (as defined below) to construct all initial leasehold improvements in
compliance with Final Plans (as defined below). The work which is to be
performed pursuant to Final Plans and this Agreement is referred to as the
"Tenant Improvements".

               1.2. Tenant Improvement Costs. The cost of performing the Tenant
Improvements, including without limitation the costs described in Section 6
below (collectively, the "Tenant Improvement Costs") shall be paid by Tenant in
the manner set forth in Section 5.

               1.3. Construction Allowance. In the manner provided in this
Section 5, Landlord shall provide an allowance for the Tenant Improvement Costs
in an amount equal to equal to Thirty and 00/100 Dollars ($30.00) multiplied by
the Rentable Area of the Premises (the "Construction Allowance"). If the cost of
Tenant Improvements is less than the Construction Allowance, Tenant shall be
entitled to a credit for any unused portion of the Construction Allowance in the
form of rent abatement of the rent first becoming due under the Lease.

        2. Approval of Plans for Tenant Improvements.

               2.1. Notification of Architect. Tenant hereby notifies Landlord
that it has engaged Richard Pollack & Associates having an address of 214 Grant
Street, San Francisco, California, who is licensed architect, as Tenant's
architect of record for the Tenant Improvements ("Architect"). Tenant's
Architect shall prepare plans for the Tenant Improvements and shall be retained
by Tenant for administrative services throughout the performance of Tenant
Improvements.

               2.2. Submittal of Plans.

                      2.2.1. Preliminary Plans. On or before March 15, 2000,
Tenant shall deliver to Landlord, for Landlord's review and approval,
"Preliminary Plans" which shall include the following: (i) floor plans; (ii)
preliminary architectural finish schedule; and (iii) sufficient detail showing
the location of electrical, mechanical and plumbing to permit pricing. Within
five (5) business days after Landlord's receipt of Preliminary Plans, Landlord
shall either approve or disapprove Preliminary Plans, which approval shall not
be unreasonably withheld. Failure by Landlord to respond within such five (5)
day period shall be conclusively deemed approval. If Landlord disapproves
Preliminary Plans, then Landlord shall state in reasonable detail the changes
which Landlord requires to be made thereto. Landlord hereby approves the


                                       1


<PAGE>   38
description of the Tenant Improvements attached as Schedule III hereto and shall
not withhold consent to the Preliminary Plans or the Final Plans to the extent
the same are consistent with such description and provided that the Tenant
Improvements as described therein will not materially adversely affect the
structure of the Building, the Building systems or the exterior of the Building
nor violate any Laws or Environmental Laws.

                      2.2.2. Preliminary Budget. Landlord shall retain a
third-party general contractor for the construction of the Tenant Improvements.
Tenant shall have the right to approve the fee for the general contractor and
the general conditions of the construction contract between Landlord and
Contractor for the construction of the Tenant Improvements, which approval shall
not be unreasonably withheld or delayed. Ten (10) days after approval by
Landlord and Tenant of Preliminary Plans, Contractor shall prepare a preliminary
budget for the Tenant Improvements based upon the approved Preliminary Plans,
which Contractor shall submit to Tenant for its review and approval. Within five
(5) days after Tenant's receipt of the preliminary budget, Tenant shall either
approve or disapprove the preliminary budget. If Tenant reasonably rejects such
preliminary budget, Tenant shall, within five (5) days of Tenant's delivery of a
written rejection notice to Landlord, require Architect to revise the
Preliminary Plans to reduce the cost of the Tenant Improvements. Following
Tenant's instructions to the Architect, Landlord and Tenant shall again follow
the procedures set forth in Section 2.2.1 and this Section 2.2.2 with respect to
the approval of the Preliminary Plans and to the submission and approval of the
preliminary budget from Contractor.

                      2.2.3. Final Plans. Within fifteen (15) business days
after Landlord and Tenant's approval of the preliminary budget for the Tenant
Improvements, Tenant shall cause the Architect to deliver to Landlord, for
Landlord's review and approval, complete plans, specifications and working
drawings which incorporate and are consistent with Preliminary Plans and the
preliminary budget, as previously approved by Landlord, and which show in detail
the intended design, construction and finishing of all portions of Tenant
Improvements, in sufficient detail for construction ("Final Plans"). Within ten
(10) business days after Landlord's receipt of Final Plans, Landlord shall
either approve or disapprove Final Plans, which approval shall not be
unreasonably withheld. If Landlord disapproves Final Plans, then Landlord shall
state in reasonable detail the changes which Landlord requires to be made
thereto. If Landlord disapproves the Final Plans, then Landlord shall state in
reasonable detail the changes which Landlord requires to be made thereto. Tenant
shall submit to Landlord revised Final Plans within five (5) business days after
Tenant's receipt of Landlord's disapproval notice. Following Landlord's receipt
of the revised Final Plans from Tenant, Landlord shall have the right to review
and approve the revised Final Plans pursuant to this Section 2.2.3. Landlord
shall give Tenant written notice of its approval or disapproval of the revised
Final Plans within five (5) business days after the date of Landlord's receipt
thereof. If Landlord reasonably disapproves the revised Final Plans, then the
following shall occur: (i) Landlord and Tenant shall continue to follow the
procedures set forth in this Section 2.2.3 until Landlord and Tenant reasonably
approve such Final Plans in accordance with this Section 2.2.3, and (ii) the
period between the date which is ten (10) business after Landlord's reasonable
disapproval (or such earlier date if Landlord approves or disapproves the first
revised Final Plans in a period less than the 5-business days provided Landlord
above) and the eventual mutual approval of such Final Plans shall constitute a
Tenant Delay.

               2.3. Landlord's Approval. Landlord's approval of any of Tenant's
plans, signs or materials samples shall not be valid unless such approval is in
writing and signed by Landlord, or otherwise deemed approved in accordance with
the provisions of Sections 2.2.1 and/or 2.2.3 of this Agreement. Landlord's
approval of any of Tenant's plans, including any preliminary draft or version
thereof, shall not be deemed to be a representation as to their completeness,
adequacy for Tenant's intended use of the Premises or compliance with applicable
law. Tenant shall pay to Landlord all reasonable costs incurred by Landlord's


                                       2

architect in the review of Preliminary Plans and Final Plans.

        3. Construction Budget. Upon approval by Landlord and Tenant of the
Final Plans, Tenant shall propose preferred subcontractors to Landlord in
certain trades which Landlord shall reasonably approve and in all other trades
Landlord shall propose acceptable subcontractors to Tenant which Tenant shall
reasonably approve and from such lists Landlord shall instruct Contractor to
obtain competitive bids for the Tenant Improvements from at least three (3)
subcontractors for each of the major subtrades and to submit the same to
Landlord and Tenant for their review and approval. Landlord shall select the
lowest bid unless Tenant agrees otherwise. Upon selection of the subcontractors
and approval of the bids, Contractor shall prepare a cost estimate for the
Tenant Improvements described in such Final Plans, based upon the bids submitted
by the subcontractors selected. Contractor shall submit such cost estimate to
Landlord and Tenant for their review and approval. Within five (5) days after
their receipt of the cost estimate, Landlord and Tenant shall each either
approve or disapprove the cost estimate, which approval shall not be
unreasonably withheld. Tenant's failure to approve or disapprove the cost
estimate within such 5-day period shall constitute grounds for the assertion of
a Tenant Delay. Landlord or Tenant may each approve or reject such cost estimate
in their reasonable sole discretion. If either Landlord or Tenant rejects such
cost estimate, Landlord shall resolicit bids based on such Final Plans, in
accordance with the procedures specified above. Following any resolicitation of
bids by Landlord pursuant to this Section 3, Landlord and Tenant shall again
follow the procedures set forth in this Section 3 with respect to the submission
and reasonable approval of the cost estimate from Contractor; provided, however
that the period between Tenant's disapproval of the first revised cost estimate
and the eventual mutual approval of a cost estimate shall constitute a Tenant
Delay. Tenant shall have the right to revise the Final Plans to reduce the
Tenant Improvement Costs but the time required to do so and delays in the
construction schedule as a result thereof shall constitute a Tenant Delay.

        4. Landlord to Construct. The construction contract shall specify and
Landlord shall use best efforts to cause Contractor to construct the Tenant
Improvements in a good and workmanlike manner, in accordance with the approved
Final Plans and in compliance with all applicable Laws. Architect shall be
responsible for promptly obtaining all necessary building permits and approvals
and other authorizations from governmental agencies required in connection with
the Tenant Improvements. The cost of all such permits and approvals, including
inspection and other building fees required to obtain the permits for the Tenant
Improvements, shall be included as part of the Tenant Improvement Costs. Tenant
shall have the benefit of any warranties provided by Contractor, the
subcontractors and suppliers in connection with the Tenant Improvements.
Landlord shall diligently prosecute construction of Landlord's Work and the
Tenant Improvements to completion. Landlord, Tenant, Contractor and Architect
shall hold weekly meetings to discuss the status of the construction. Landlord
shall provide Tenant with current construction schedules, including the
estimated date of completion.

        5. Payment for Tenant Improvements. The Tenant Improvement Costs shall
be paid solely by Tenant as follows:

               5.1 Method of Payment. Landlord shall bear the Tenant Improvement
Costs up to the amount of the Construction Allowance; and Tenant shall be
responsible for paying any excess in the Tenant Improvement Costs over the
amount of such Construction Allowance. For the purposes of this Agreement, the
term "Tenant's Share of Tenant Improvement Costs" shall mean the entire amount
of all Tenant Improvement Costs, less the Construction Allowance provided by
Landlord.

                      5.1.1. Payment. Within twenty (20) days after Landlord's
receipt of reasonably satisfactory invoices for costs of labor and materials
incurred in connection with the Tenant Improvements, together with such
supporting documentation and lien waivers as Landlord may reasonably require in
order to review the costs covered by the billing, Landlord shall pay the Tenant
Improvement Costs represented by such invoices first coming due for payment, up
to an aggregate


                                       3


<PAGE>   40
amount equal to the Construction Allowance. As and when any amount of Tenant's
Share of Tenant Improvement Costs become due and payable, Tenant shall pay such
Tenant Improvement Costs to Landlord within fourteen (14) days after the date of
Tenant's receipt of Landlord's written request therefor, together with such
supporting documentation and lien waivers as Tenant may reasonably require in
order to review the costs covered by the billing. Any failure by Tenant to pay
any amount of Tenant's Share of Tenant Improvement Costs as and when required
under this Agreement shall constitute a default by Tenant under the Lease after
notice and applicable cure period provided under the Lease. Notwithstanding the
foregoing, Tenant may elect to have Landlord finance Tenant's Share of Tenant
Improvement Costs in an amount up to Five and 00/100 ($5.00) per square foot of
Rentable Area by amortizing the Tenant's Share of Tenant Improvement Costs over
the Initial Term at an interest rate of ten percent (10%) per annum. Tenant
shall make such election within five (5) days of the approval of the
construction budget pursuant to Sections 2 and 3 and within ten (10) days
following such election, Landlord and Tenant shall enter into an amendment to
the Lease providing for the increase in Base Rent.

                      5.1.2. Penalties. To the extent that any contractor or
subcontractor working on the Tenant Improvements imposes upon Landlord any
penalty or late charge due to Tenant's failure to pay to Landlord any amount due
under this Section 5.1 as and when such amount is due, Tenant shall be solely
responsible for paying such penalty or late charge; provided, however, that if
Tenant disputes the imposition of such penalty or late charge, Tenant shall not
be required to pay the penalty or late charge until the dispute has been settled
or otherwise resolved; provided further, that if any penalty or late charge is
imposed due to Tenant's exercise of its rights under this Section 5.1.3, Tenant
shall pay such penalty or late charge as provided in this Section 5.1.3.

               5.2 Extra Work. Tenant shall be solely responsible for any and
all costs and expenses arising from any improvements to or installations in the
Building desired by Tenant and approved by Landlord that are outside the scope
of the Final Plans.

        6. Tenant Improvement Costs. The Tenant Improvement Costs shall include

engineering plans and specifications for the Tenant Improvements, including
engineering costs associated with completion of the State of California energy
utilization calculations under Title 24 legislation required in connection with
the Tenant Improvements; provided however that only Two and 50/100 Dollars
($2.50) per square foot of Rentable Area for such costs may be allocated to the
construction allowance and any costs in excess thereof shall be allocated to
Tenant's Share of Tenant's Improvement Costs.

               6.2 All costs of obtaining building permits and other necessary
authorizations from the City of San Francisco;

               6.3 All costs of interior design and finish schedule plans and

made by either Landlord or Tenant unless approved in writing by both parties.
Landlord agrees to make all changes (i) required by any public agency to conform
with governmental regulations, or (ii) requested in writing by Tenant and
approved in writing by Landlord, which approval shall not be unreasonably
withheld. Any costs related to such changes shall be added to the Tenant

billing for such additional costs shall be accompanied by evidence of the
amounts billed as is customarily used in the business. Costs related to changes
shall include, without limitation, any architectural, structural engineering, or
design fees, and the Contractor's price for effecting the change. Any change
order which may extend the date of substantial completion of the Tenant
Improvements may be disapproved by Landlord unless Tenant agrees that for all
purposes under this Lease, the Tenant Improvements shall be deemed to have been
substantially completed on that date on which such Tenant Improvements would
have been substantially completed without giving effect to the change order in
question. All change orders shall specify any change in the cost estimate as a
consequence of the change order.

        8. Acceptance of Building. When Landlord's Work and Tenant Improvements

certify in writing that Contractor has substantially completed the Landlord's
Work and the Tenant Improvements, notwithstanding that minor details of
construction, mechanical adjustment or decorations which do not materially
