                               PROSPECTUS SUMMARY
 
     This summary highlights information in this prospectus. You should read the
entire prospectus carefully, especially the risks of investing in our common
stock discussed under "Risk Factors," before investing in our common stock.
 
     We are a leading provider of email and advanced messaging solutions on the
Internet for consumers, Web portals and businesses. As of March 31, 1999, we
managed over 9.6 million mailboxes across all of our service offerings and
processed over 190 million messages during the month of March 1999. Our consumer
email service, NET@DDRESS (www.netaddress.com), is the largest independent
Web-based email service on the Internet with more than 6.7 million mailboxes.
Netscape and register.com, a business-oriented portal site, constitute our
primary Web portal clients. We currently manage over 2.7 mailboxes for
Netscape's Netcenter Web portal. Our commercial messaging solutions include
specialized business applications for companies such as American Express Travel
Related Services Company, as well as comprehensive message outsourcing services
for a wide range of businesses. We base our messaging solutions on highly
reliable and scalable technology that includes advanced features, universal
accessibility and a high level of security.
 
     The Internet is quickly becoming an important communications tool,
advertising medium and sales channel for both consumers and businesses
worldwide. We believe that email and advanced messaging services will continue
to be key drivers of Internet usage and growth because they are among the most
popular Internet applications today. According to Forrester Research, the number
of email users in the U.S. is expected to increase from 75 million in 1998 to
135 million in 2001. Jupiter Communications projects that the total number of
email messages sent per day in the United States will increase from 246 million
in 1998 to 576 million in 2002. In addition, Jupiter Communications estimates
that online advertising revenue will grow from approximately $1.9 billion in
1998 to approximately $7.7 billion in 2002.
 
     We believe that many businesses, including those that have already
implemented their own in-house email systems, will outsource their messaging
services to ensure a more reliable, cost effective and less resource-intensive
solution. According to the Gartner Group, the percentage of large businesses
that expect to outsource at least some of their email systems is estimated to
grow from 10% in 1998 to 25% in 2000.
 
     We have developed a range of reliable, easy-to-use advanced messaging
solutions to meet the following needs of consumers, Web portals and businesses:

     CONSUMERS. In April 1996, we launched NET@DDRESS, the first Web-based email
service for consumers.
 
     - NET@DDRESS is offered free of charge to consumers. We generate revenue
       from NET@DDRESS by selling advertising space and by offering fee-based
       premium services such as virus scanning, email forwarding and message
       notification.
 
     - Since January 1, 1999, NET@DDRESS has added an average of 11,465
       mailboxes per day.
 
     - In 1998, NET@DDRESS won awards for its superior features from PC
       Magazine, CNET and Windows Magazine.
 
                                        1
<PAGE>   6
 
     - In December 1998, MediaMetrix, an Internet usage measuring firm, ranked
       NET@DDRESS as the sixth most popular site on the Web based on time spent
       online by Internet users.
 
     WEB PORTALS. We provide our solutions to Web portals to enhance our
reputation as a premier provider of messaging services and to build our brand
awareness among both consumers and businesses.
 
     - We host and manage the Web-based email services for Netscape's Netcenter
       Web portal. Since launching Netscape WebMail Powered by USA.NET in July
       1998, we have signed up over 2.7 million mailboxes.
 
     - We are also developing foreign language-based email services for certain
       of Netscape's international Netcenter Web portals.
 
     - We generate revenue from Netscape WebMail by selling advertising space
       through our internal sales force and from fee-based premium services. We
       share this advertising and premium services revenue with Netscape.
 
     - In September 1998, PC Magazine recognized Netscape WebMail as the
       top-ranked Web-based email service in a review of the features of 12
       major Web portals.
 
     - In March 1999, we entered into an agreement with register.com to offer
       businesses an integrated solution that combines our email and advanced
       messaging solutions with register.com's domain name registration service.
       We plan to generate revenue by charging a monthly fee for each mailbox
       established through this relationship.
 
     BUSINESSES. Our commercial messaging solutions are designed to meet
specific business needs and provide comprehensive message outsourcing solutions.
 
     - In April 1998, together with American Express, we launched AmExMail, a
       Web-based email service that is available to all consumers but has
       special features available exclusively to American Express Cardmembers.
 
     - In June 1998, we introduced our outsourcing service to handle the
       increasingly complex messaging requirements of businesses on a
       cost-effective and reliable basis. We currently market our services to
       companies in a variety of industries, including Internet service
       providers, wireline and wireless telecommunications companies,
       publishers, information technology service companies, professional
       service providers and consumer products companies.
 
     - We generate revenue from these application-specific and outsourcing
       solutions primarily by charging a monthly fee for each mailbox. We also
       offer fee-based premium services and sell advertising in select
       situations.
 
     Our objective is to be the leading provider of email and advanced messaging
solutions for consumers, Web portals and businesses. We intend to pursue this
objective by developing specialized applications to solve unique business needs,
expanding our message outsourcing services, continuing our leadership in
consumer messaging, developing and strengthening our relationships with Web
portals, maintaining our technology leadership position and providing superior
customer service. We believe that our proven experience in meeting the rapidly
evolving messaging needs of consumers, Web portals and businesses positions us
to capitalize on the continuing rapid growth of Internet-based messaging.

                                  RISK FACTORS
 
     This offering involves a high degree of risk. You should carefully consider
the risks and uncertainties described below and the other information in this
prospectus before deciding whether to invest in shares of our common stock. The
risks and uncertainties described below are not the only ones we face.
Additional risks and uncertainties not presently known to us or that we
currently deem immaterial may also impair our business.
 
     If any of the following risks actually occur, our business, operating
results or financial condition could be materially adversely affected. This
could cause the trading price of our common stock to decline, and you may lose
part or all of your investment.
 
WE DEPEND ON CONTINUED GROWTH IN THE MARKET FOR OUR SERVICES
 
     The market for Web-based email and advanced Internet messaging services is
new and rapidly evolving. We only recently launched our commercial messaging
services. Our future success depends on businesses' widespread acceptance and
use of outsourcing to solve their email and advanced Internet messaging needs.
Although we have experienced growth in revenue and users in the past, we may not
sustain these growth rates and these growth rates may decrease in the future.
These growth rates may not indicate actual growth rates that we may experience.
We are uncertain if the market for our services will continue to grow and
develop. A number of factors may inhibit the growth of the market for our
services, such as:
 
     - Businesses may be reluctant to outsource their email and advanced
       Internet messaging services;
 
     - Internet users may not want to adopt Web-based email solutions;
 
     - We may be unable to forecast the features and functionality our potential
       users require;
 
     - We may be unable to market our services to new users;
 
     - We may be unable to differentiate our services from those of our
       competitors;
 
     - Our competitors may introduce new services;
 
     - New services that we launch that are not favorably received could damage
       our reputation; and
 
     - We may be unable to maintain and strengthen our brand awareness.
 
     If the market for our services fails to develop, develops more slowly than
we expect, or if we fail to accurately design our service enhancements to
satisfy our users on a timely basis, or at all, our business, operating results
and financial condition would be materially adversely affected.
 
IT IS DIFFICULT TO EVALUATE OUR BUSINESS BECAUSE WE HAVE A LIMITED OPERATING
HISTORY
 
     We did not begin to offer Web-based email services until April 1996 and
commercial messaging services until June 1998. Accordingly, we have only a
limited operating history upon which you can evaluate our business and
prospects. In addition, we have only been selling our commercial messaging
services for a short time. As a young company, we face risks and uncertainties
relating to our ability to successfully implement our business plan. You should
consider the risks, expenses and difficulties encountered by companies in their
early stages of development, particularly companies in new and rapidly evolving
markets. If we do not successfully address these risks and uncertainties, our
business, operating results and financial condition will be materially adversely
affected.
 
WE HAVE A HISTORY OF LOSSES AND WE EXPECT TO LOSE MONEY IN THE FUTURE
 
     We have not achieved profitability and we expect to incur net losses for
the foreseeable future. We incurred net losses from continuing operations of
approximately $19.2 million in 1998, $5.7 million in 1997 and $2.1 million in
1996. As of December 31, 1998, our accumulated deficit was $28.6 million.
 
                                        5
<PAGE>   10
 
     We expect to continue to lose money for the foreseeable future because we
plan to continue to incur significant operating expenses. We have not generated
enough revenue to cover the substantial amounts we have spent to create, launch
and enhance our services. If our revenue does not increase substantially, we may
never become profitable. Even if we do achieve profitability, we may not sustain
or increase profitability on a quarterly or annual basis in the future. Our
operating costs have exceeded our revenue for all quarters. We have historically
funded our operations by selling stock and obtaining loans from banks and not by
generating income from our business.
 
WE FACE RISKS IN OUR STRATEGIC RELATIONSHIPS
 
     Our strategic relationships expose us to a number of significant risks and
uncertainties, such as:
 
     - The relationships may not be renewed at the end of their respective terms
       on commercially reasonable terms or at all;
 
     - We may fail to generate sufficient advertising and other revenue to
       offset the expenses and resources we devote to developing, maintaining
       and enhancing such services;
 
     - The resources we need to devote to our services may be greater than we
       anticipate; and
 
     - These relationships may divert our resources and our management's time
       and attention away from our other services, including NET@DDRESS and our
       commercial messaging services.
 
     Our agreement with American Express terminates in July 1999. Our agreement
with Netscape with respect to its domestic Netcenter site terminates in June
2000. Our agreement with Netscape with respect to certain international
Netcenter sites terminates two years following the initial service launch. These
termination dates may be as early as April 2001. These agreements may be
terminated early in certain circumstances and they do not contain any automatic
renewal or extension period. Our partners may not renew them at the end of their
respective terms. Further, these relationships provide that American Express and
Netscape will retain the users of the service if the agreements are terminated.
 
     We do not know what impact America Online's merger with Netscape will have
on our relationship with Netscape. America Online provides its subscribers with
email services. It may also use technology provided by certain of our
competitors or invest in or have relationships with our competitors or other
Internet companies. These relationships may result in potential conflicts of
interest, which may not be resolved in our favor. In addition, advertising
revenue on Netscape WebMail Powered by USA.NET accounted for approximately 30%
of our gross revenue in 1998. If Netscape does not renew this relationship and
if we do not replace it with an another significant Web portal strategic
relationship, then our business, operating results and financial condition would
be materially adversely affected.
 
     Our relationships with our existing and future strategic partners may limit
our ability to enter into other strategic relationships or sell our services to
similar businesses. Many companies we may pursue for strategic relationships
also offer competing products and services. As a result, these companies may be
reluctant to enter into strategic relationships with us. Please see our
discussion in "Business -- Strategic Relationships" for additional information
regarding our strategic relationships.
 
WE FACE INTENSE COMPETITION
 
     We face intense competition in the Web-based email and advanced Internet
messaging services markets. Competition for Internet-based advertising is also
intense. We expect competition to persist and intensify. Barriers to entry may
be insubstantial and we may face substantial and growing competitive pressures
from companies both in the United States and abroad. If we do not respond
successfully to competitive pressures, our business, operating results and
financial condition would be materially adversely affected.
 
     We may not be able to compete successfully against our current or future
competitors. Many of our competitors have greater brand recognition, longer
operating histories, larger customer bases and greater
 
                                        6
<PAGE>   11
 
financial, marketing and other resources than we have. These factors may place
us at a disadvantage when we respond to our competitors' pricing strategies,
technological advances and other initiatives. Our inability to successfully
respond to competitive pressures would have a material adverse effect on our
business, operating results and financial condition. Additionally, our
competitors may develop services that are superior to ours or that achieve
greater market acceptance. Please refer to "Business -- Competition" for further
discussion of the companies that we compete against.
 
WE FACE RISKS OF UNPLANNED SYSTEM INTERRUPTIONS AND CAPACITY CONSTRAINTS
 
     The performance of our network and technological infrastructure is critical
to our success. Our computer and communication hardware systems must operate
efficiently and without interruption. Our systems are currently located at our
data center facilities in Colorado Springs, Colorado. They are vulnerable to
damage from fire, floods, power loss, telecommunications failures, physical
break-ins and similar events.
 
     Our business will suffer if we experience frequent or long system
interruptions. Our customers have experienced some interruptions in our email
service in the past. We believe that these interruptions are likely to occur
from time to time in the future. System failures that cause interruption or
slower response times could result in less traffic to our Web site and those of
the Web portals with whom we partner. Sustained or repeated system failures
could cause us to lose advertisers and users and damage our reputation. These
interruptions may be due to hardware or software failures, unsolicited bulk
mail, computer viruses or "spam" attacks or other causes.
 
     In addition, increased email traffic could cause capacity constraints.
These constraints could result in unanticipated system disruptions, slower
response times, impaired quality and reduced levels of customer service. Slower
response times or system failures could adversely affect our delivery of
advertising impressions. Accordingly, our advertising revenue would decline. If
these problems were to continue, our business, operating results and financial
condition would be materially adversely affected.
 
WE FACE RISKS ASSOCIATED WITH RAPID TECHNOLOGICAL CHANGE
 
     Rapid technological change, changing customer needs, frequent new product
and service introductions and evolving industry standards characterize the
Internet messaging market. These market characteristics could render our
existing services, technology and systems obsolete. We must continually improve
the performance, features and reliability of our services to respond to evolving
market demands and competition. Our business, operating results and financial
condition would be materially adversely affected if we are unable to respond in
a cost-effective and timely manner to changing market conditions or customer
requirements.
 
WE MUST UPGRADE OUR SYSTEMS AND INFRASTRUCTURE TO ACCOMMODATE INCREASES IN EMAIL
TRAFFIC
 
     We must continue to expand and adapt our network infrastructure to
accommodate the number of users and the amount of transmitted information. We
plan to expand our data center operations and network infrastructure in the near
future. The expansion and adaptation of our network will require substantial
financial, operational and management resources. We do not know if we will be
able to successfully connect and manage a substantially larger number of users
at high transmission speeds. We also face risks related to our network's ability
to maintain expected performance levels with more users.
 
     We will also need to make additional investments in our network
infrastructure as the frequency and complexity of messaging increases. The
proliferation of multimedia technology and other new methods of communicating on
the Internet which require large amounts of data may further constrain our
systems and infrastructure. Message infrastructure investments may be expensive
and time consuming. Additionally, 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. We may also not be able to
achieve or maintain a sufficiently high capacity of data transmission as
customer usage increases.
 
                                        7
<PAGE>   12
 
     We are likely to encounter equipment or software incompatibility as we
upgrade our infrastructure. We may not be able to expand or adapt our
infrastructure to meet additional demand or our users' changing requirements in
a timely manner or at all. If we fail to do so, our business, operating results
and financial condition would be materially adversely affected.
 
WE FACE RISKS ASSOCIATED WITH INTERNET COMMUNICATIONS AND SYSTEM SECURITY
 
     We must securely transmit confidential information over public networks.
People may attempt to breach our security or that of our users to misappropriate
proprietary information or cause interruptions in our operations. Security
breaches that result in access to confidential information could damage our
reputation and expose us to a risk of loss or liability.
 
     Our servers are vulnerable to computer viruses, physical or electronic
break-ins and similar disruptions. These problems could lead to interruptions,
delays or loss of data. We may need to expend significant capital and other
resources to protect against security breaches or to alleviate problems caused
by any breach. Our failure to prevent security breaches may have a material
adverse effect on our business, operating results and financial condition.
 
WE DEPEND ON THIRD PARTIES TO DISTRIBUTE OUR COMMERCIAL MESSAGING SOLUTIONS
 
     We sell our commercial messaging solutions through our internal sales force
and indirect channels such as Internet, telecommunications and other service
providers, as well as distributors, resellers and Web portals. To the extent
these third parties do not successfully distribute our services, or the amounts
we pay these third parties to market and sell our services do not provide
adequate incentives, our business, operating results and financial condition
would be materially adversely affected.
 
WE FACE RISKS BY RELYING ON THIRD PARTY TECHNOLOGIES
 
     We license certain technology from third parties, such as Sun Microsystems
and Oracle. We expect to increase our reliance on third party technology in the
future to enhance our services and remain competitive. We may not be able to
license these technologies on commercially reasonable terms or at all. In
addition, we may fail to successfully integrate licensed technology into our
systems. Our inability to obtain any of these licenses could delay service
development or the timely introduction of new services and divert our resources.
Any such delays could materially adversely affect our business, operating
results and financial condition.
 
OUR SERVICES MAY BE AFFECTED BY UNKNOWN SOFTWARE DEFECTS
 
     Our services depend on complex software developed by us and third parties.
Software often contains defects, particularly when first introduced or when new
versions are released. We may not discover software defects that affect our
services or enhancements until we deploy the software. These defects could cause
service interruptions, which could damage our reputation, increase our service
costs, cause us to lose revenue, delay market acceptance or divert our
development resources, any of which could materially adversely affect our
business, operating results and financial condition.
 
OUR ANNUAL AND QUARTERLY OPERATING RESULTS ARE SUBJECT TO SIGNIFICANT
FLUCTUATIONS
 
     Our annual and quarterly operating results have fluctuated significantly in
the past and we expect them to fluctuate significantly in the future. Our
operating results fluctuate because of a variety of factors, not all of which
are in our control. These factors include:
 
     - Our expenses and revenue from our strategic relationships;
 
     - The timing of our or our competitors' introduction of new, enhanced or
       alternative email services and the market acceptance of those services;
 
     - The amount and timing of revenue, operating costs and capital
       expenditures;

       usage;
 
     - Pricing, service or marketing decisions that we make in response to
       competition;
 
     - System downtime or technical difficulties that affect our operations or
       the Internet in general; and
 
     - Economic conditions relating to the Internet and general economic
       conditions.
 
     In addition, we base our operating expenses largely on our expectations of
future revenue. Accordingly, our operating results are particularly sensitive to
fluctuations in revenue because we may be unable to adjust spending quickly
enough to offset any unexpected revenue shortfall. If our revenue is below our
plan, or if we increase our spending ahead of our revenue growth, our business,
operating results and financial condition would be materially adversely
affected.
 
     You should not rely on annual or quarter-to-quarter comparisons of our
operating results as an indication of future performance. It is possible that in
some future periods our results may be below expectations of public market
analysts and investors. If this were to occur, the price of our common stock
would likely fall.
 
WE MUST ESTABLISH, MAINTAIN AND STRENGTHEN OUR BRANDS
 
     To be successful, we believe that we must establish, maintain and
strengthen our brands. We must succeed in our marketing efforts, provide
high-quality services and increase our user base to build our brand awareness.
These efforts have required, and will continue to require, significant expenses.
If consumers, Web portals, businesses or advertisers do not perceive our
services to be of high quality, or if users reject our new services, the value
of our brands would be diluted. If we are unable to establish, maintain and
strengthen our brands, our business, operating results and financial condition
would be materially adversely affected.
 
WE DEPEND ON KEY PERSONNEL AND OUR ABILITY TO HIRE ADDITIONAL PERSONNEL
 
     We believe that our success will depend on the continued services of our
senior management team and other key personnel. The loss of the services of any
of our senior management team or other key employees could materially adversely
affect our business, operating results and financial condition. We do not have
long-term employment agreements with any of our senior management or other key
personnel.
 
     Our future success also depends on our ability to identify, attract, hire,
train, retain and motivate highly skilled technical, managerial and sales and
marketing personnel. For example, the complexity and implementation of our
Internet messaging services requires highly trained sales and marketing
personnel to educate prospective users regarding the use and benefits of our
services. We recently expanded and expect to continue to expand our operations.
Competition for skilled personnel is intense, and we cannot guarantee that we
will successfully attract, assimilate or retain a sufficient number of qualified
personnel. In particular, we have experienced difficulties in retaining
employees due to significant competition for experienced personnel in our
market. Our failure to attract and retain the necessary technical, managerial,
sales and marketing and administrative personnel could materially adversely
affect our business, operating results and financial condition.
 
WE MAY NOT MANAGE OUR GROWTH EFFECTIVELY
 
     Our recent rapid growth has significantly strained our managerial,
operational and financial resources. We expect to continue to significantly
augment our infrastructure at an accelerated pace. We must effectively manage
our operational, customer service and financial systems, procedures and controls
to manage this future growth. Our failure to manage our growth effectively could
materially adversely affect our business, operating results and financial
condition.

WE MAY LOSE USERS BECAUSE OF "SPAM"
 
     Unsolicited bulk mail, or "spam," and our attempts and other's attempts to
control spam could harm our business. Technologies and processes designed to
detect and block spam are not entirely effective. As a result, unwanted spam may
be delivered while legitimate messages are not delivered. To the extent our spam
blocking efforts are not effective, our systems may become unavailable or may
suffer from reduced performance. Additionally, spam-blocking efforts by others
may result in others blocking our users' legitimate messages. Any of these
events may cause users to become dissatisfied with our service and terminate
their use of our services, which could cause our business, operating results and
financial condition to be materially adversely affected.
 
WE RELY ON GENERATING REVENUE FROM ADVERTISING ON THE INTERNET
 
     We have derived substantially all of our revenue to date from the sale of
advertisements. Advertising customers may not continue to purchase advertising
space and services from us. We may not be successful in attracting additional
advertisers or achieving sufficient page impressions for our advertisers. If the
Internet advertising market develops more slowly than we expect or if we are
unsuccessful in increasing our advertising revenue, our business, operating
results and financial condition will be materially adversely affected. We expect
that revenue from Internet advertising will continue to account for a
significant amount of our revenue for the foreseeable future. Since the Internet
advertising market is new and rapidly evolving, it is difficult for us and
advertisers to gauge its effectiveness as compared to traditional advertising
outlets.
 
     In addition, many of our current advertising customers have limited or no
experience using the Internet as an advertising medium and have not devoted a
significant portion of their advertising expenditures to the Internet. Further,
advertisers may not find our advertising to be effective for promoting their
products and services.
 
     It is important to our advertisers that we accurately measure the
demographics of our user base and the delivery of advertisements. We depend on
third parties to provide certain of these measurement services. If they are
unable to provide these services in the future, we will need to perform them
ourselves or obtain them from another provider. This could cause us to incur
additional costs or cause interruptions in our business. Companies may choose
not to advertise with us or may pay less for advertising if they do not perceive
our measurements or measurements provided by third parties to be reliable.
 
     It is difficult to predict which pricing models Internet advertisers will
accept. This uncertainty makes it difficult to project our future advertising
rates and revenue. Our revenue could be adversely affected if advertisers reject
our pricing models. Also, "filter" software programs that limit or prevent us
from delivering advertising to a user's computer are available. Widespread
adoption of this software could adversely affect the commercial viability of
Internet advertising.
 
WE FACE RISKS UNDER OUR ADVERTISING CONTRACTS
 
     We derive a significant portion of our revenue from short-term advertising
contracts that typically last one to two months. Our revenue and operating
results for a given quarter will depend to a significant extent on contracts
entered into within that quarter. The cancellation or deferral of advertising
contracts, or the failure to obtain sufficient new advertising contracts, could
materially adversely affect our business, operating results and financial
condition.
 
     Our advertising revenue is based in part on the amount of traffic to the
sites on which we sell advertising. Any significant shortfall in traffic in
these sites could have a material adverse effect on our business, operating
results and financial condition. In addition, substantially all of our
advertising contracts require that we guarantee a minimum number of impressions.
If we do not meet these minimum impressions, we must provide credit for
additional impressions. Our ability to sell additional advertising would be
materially adversely affected and our advertising rates may decline.
 
                                       10
<PAGE>   15
 
THE LOSS OF A MAJOR ADVERTISER COULD HARM OUR BUSINESS
 
     In 1998, Egghead.com accounted for approximately 27% of our total revenue.
In 1997, Egghead.com, 24/7 Media (an advertising agency that buys advertising on
behalf of others) and Webstakes accounted for approximately 18%, 15% and 11%,
respectively, of our total revenue. Generally, our advertising agreements are
short-term and can be easily terminated by the other party. Sales of our
advertising space or of our services to a limited number of customers could
account for a high percentage of our revenue in the future. Our future success
depends on our ability to retain our existing customers and attract new
customers. The loss of a major customer or our inability to attract new
customers could have a material adverse effect on our business, operating
results and financial condition.
 
WE DEPEND ON THE CONTINUED GROWTH OF THE INTERNET
 
     Our success depends on consumers and businesses increasing their use of the
Internet. Consumers and businesses might not use the Internet for a number of
reasons, such as:
 
     - High Internet access costs;
 
     - Perceived security risks;
 
     - Legal and regulatory issues;
 
     - Inconsistent service quality; and
 
     - Unavailability of cost-effective, high-speed service.
 
     Even if consumers and businesses increase their use of the Internet, the
Internet infrastructure may not be able to support the demands of this growth.
Further, the Internet's performance and reliability may decline. Similarly,
users may experience interruptions in their services as a result of outages and
other delays occurring throughout the Internet network infrastructure. If these
outages or delays occur frequently, consumers and businesses may slow or stop
their use of the Internet as a commercial or business medium. If consumers and
businesses do not increase their use of the Internet, our business, operating
results and financial condition would be materially adversely affected.
 
WE DEPEND ON COST-EFFECTIVE, EFFICIENT TRANSMISSION OF DATA OVER THE INTERNET
 
     The recent growth of the Internet has caused frequent interruptions and
delays in accessing the Internet and in transmitting data over the Internet. Any
deterioration in the performance of the Internet as a whole could undermine the
benefits of our services. We rely on the speed and reliability of the networks
operated by third parties. Therefore, we depend on improvements being made to
the entire Internet infrastructure to alleviate overloading and congestion.
 
     In addition, we rely on a number of public and private Internet
connections, which are arrangements among access providers to carry each other's
traffic. Our ability to transmit our message traffic would be reduced if these
providers were to discontinue these arrangements and alternative providers did
not emerge or were to increase the cost of providing access.
 
WE FACE RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS
 
     We intend to expand into international markets and to spend significant
financial and managerial resources to do so. We have limited experience in
international markets and may not be able to compete effectively in
international markets. We also face certain risks inherent in conducting
business internationally, such as:
 
     - Legal and governmental regulatory requirements;
 
     - Difficulties and costs of staffing and managing international operations;
 
     - Differing technology standards;
 
                                       11
<PAGE>   16
 
     - Language and cultural differences;
 
     - Trade barriers;
 
     - Difficulties in collecting accounts receivable and longer collection
       periods;
 
     - Seasonal business activity in certain parts of the world;
 
     - Political and economic instability;
 
     - Fluctuations in currency exchange rates;
 
     - Imposition of currency exchange controls;
 
     - Potentially adverse tax consequences; and
 
     - Reduced protection for intellectual property rights in certain countries.
 
     Any of these factors could materially adversely affect our international
operations and, consequently, our business, operating results and financial
condition.
 
WE MAY NEED AND BE UNABLE TO OBTAIN ADDITIONAL FUNDING
 
     We believe that, following this offering, our cash reserves and cash flows
from operations should be adequate to fund our operations for at least the next
twelve months. If our capital requirements or revenue vary materially from our
current plans or if unforeseen circumstances occur, we may require additional
financing sooner than we anticipate. This financing may not be available on a
timely basis, in sufficient amounts or on terms acceptable to us. This financing
may also dilute existing stockholders.
 
     If we cannot obtain adequate funds on acceptable terms, then we may not be
able to:
 
     - Fund our capital requirements;
 
     - Take advantage of strategic opportunities;
 
     - Develop or enhance our services; or
 
     - Respond to competitive pressures.
 
     Any of these failures could have a material adverse effect on our business,
operating results and financial condition.
 
OUR SYSTEMS MAY NOT BE YEAR 2000 COMPLIANT
 
     The Year 2000 issue may impact our internal information technology ("IT")
and non-IT systems. We use software and hardware developed by third parties both
for our network and internal information systems. We rely on third party network
infrastructure providers to gain access to the Internet. We have not performed
any testing of such third-party software or hardware to determine Year 2000
compliance.
 
     Failure of our internal computer systems or third party hardware or
software, or of systems maintained by third parties, to operate properly with
regard to Year 2000 and thereafter could cause systems interruptions or loss of
data or could require us to incur significant unanticipated expenses to remedy
any problems. Presently, we believe we are unable to reasonably estimate the
duration and extent of any such interruption, or quantify the effect it may have
on our future revenue. We have not yet developed a comprehensive contingency
plan to address these issues, which could result from such failure. We are
prepared to develop such a contingency plan if our ongoing assessment indicates
areas of significant exposure.
 
     If our present efforts to address the Year 2000 compliance issues are not
successful, or if third party vendors, licensors and providers of hardware,
software and services with which we conduct business do not successfully address
such issues, our business, operating results and financial condition would be
materially
 
                                       12
<PAGE>   17
 
adversely affected. Please refer to our discussion in "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Year 2000
Issues."
 
WE MAY BE EXPOSED TO RISKS OF INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS
INFRINGEMENT
 
     Trademarks, service marks, trade secrets, copyrights and other proprietary
rights are important to our success and competitive position. We seek to protect
our proprietary rights, but our efforts may be inadequate to protect our
proprietary rights or to prevent others from claiming violations of their
proprietary rights. Effective trade secret, copyright, patent and trademark
protection may not be available in every country in which we make our services
available through the Internet. The unauthorized misappropriation of our
proprietary technology could have a material adverse effect on our business,
financial condition and operating results. We may also be subject to claims
alleging that we have infringed third party proprietary rights. If we were to
discover that any of our services infringed a third party's rights, we may not
be able to obtain permission to use those rights on commercially reasonable
terms. If we resort to legal proceedings to enforce our proprietary rights or
defend against alleged infringements, the proceedings could be burdensome and
expensive and could involve a high degree of risk. Any of these events could
have a material adverse effect on our business, operating results and financial
condition.
 
WE MAY FACE INCREASED GOVERNMENT REGULATION AND LEGAL UNCERTAINTIES
 
     Any new legislation or regulation regarding the Internet, or the
application or uncertainty relating to the application of existing laws and
regulations to the Internet, could materially adversely affect our business,
operating results and financial condition. There are an increasing number of
laws and regulations pertaining to the Internet.
 
     Legislation in these areas could impair the growth of the Internet and
decrease the acceptance of the Internet as a communications and commercial
medium. This could decrease the demand for our services, increase our cost of
doing business or otherwise have a material adverse affect on our business,
financial condition and operating results.
 
     Further, the growth and development of the Internet messaging market may
prompt calls for more stringent consumer protection laws that may impose
additional burdens on companies conducting business online. For example, because
we rely on the collection and use of personal data from our users for targeting
advertisements, any laws or regulations that restrict our ability to collect or
use such information may harm us. Some states, including New York and
California, have enacted laws or adopted regulations that apply various consumer
fraud and false advertising requirements to parties who conduct business over
the Internet. There have also been numerous legislative initiatives proposed to
address the prevalence of spam on the Internet. These laws may impose additional
burdens on our business. Please refer to our discussion in
"Business -- Government Regulation" for additional information.
 
WE FACE RISKS FROM POTENTIAL TELECOMMUNICATIONS REGULATIONS
 
     Several telecommunications carriers are advocating that the Federal
Communications Commission regulate the Internet in the same manner as other
telecommunications services by imposing access fees on Internet service
providers. Any such regulations could substantially increase the costs of
communicating on the Internet. This, in turn, could slow the growth in Internet
use and thereby decrease the demand for our products and services or otherwise
have a material adverse effect on our business, operating results and financial
condition.
 
WE MAY BE LIABLE FOR INFORMATION RECEIVED FROM THE INTERNET AND INTERNET-RELATED
PROBLEMS
 
     As a provider of Internet messaging services, we may be subject to legal
claims involving matters such as defamation, negligence, invasion of privacy,
copyright infringement and other claims based on the nature and content of the
materials transmitted via email. We do not and cannot screen all of the content
generated by our users and we could be exposed to liability with respect to this
content. Online content restrictions cover many areas, including indecent or
obscene content and gambling. Several federal and
                                       13
<PAGE>   18
 
state regulations prohibit the transmission of indecent or obscene information
and content. Certain foreign governments 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.
 
     In October 1998, the Children's Online Privacy Protection Act was signed
into law, which directs the Federal Trade Commission ("FTC") to develop
regulations for the collection of data from children by commercial Web site
operators. Separately, the Federal Trade Commission Act prohibits unfair and
deceptive practices in and affecting commerce. The FTC Act authorizes the FTC to
seek injunctive and other relief for violations of the FTC Act and provides a
basis for government enforcement of fair information practices. For instance,
failure to comply with a stated privacy policy may constitute a deceptive
practice in some circumstances and the FTC would have authority to pursue the
remedies available under the FTC Act for any violations. Furthermore, in some
circumstances, information practices may be inherently deceptive or unfair,
regardless of whether the entity has publicly adopted any privacy policies. The
FTC has begun investigations into the privacy practices of companies that
collect information on the Internet.
 
     We are continuing to review our practices in light of the recent FTC
activity and the enactment of the Children's Online Privacy Protection Act.
However, we cannot predict the exact form of the regulations that the FTC may
adopt. Accordingly, we cannot assure you that our current practices will comply
with the regulatory scheme which the FTC ultimately adopts or that we will not
have to make significant changes to comply with such laws.
 
     At the international level, the European Union adopted a directive that
requires EU member countries to impose restrictions on the collection and use of
personal data, effective October 25, 1998. Among other provisions, the directive
generally requires member countries to prevent the transfer of
personally-identifiable data to countries that do not offer equivalent privacy
protections. At present, the EU has indicated that the United States does not
provide protections equivalent to that of the directive. The directive could,
among other things, affect United States companies that collect information over
the Internet from individuals in EU member countries, and may impose
restrictions that are more stringent than current Internet privacy standards in
the United States.
 
     We may also be subject to risks from claims resulting from unsolicited
email (or spamming), lost or misdirected messages, illegal or fraudulent use of
email or interruptions or delays in service. Even to the extent these claims do
not result in liability, we could incur significant costs in investigating or
defending against these claims, or in implementing measures to reduce our
exposure to such liability. These types of claims may also hurt our reputation.
 
     Our insurance may not cover claims of these types or may not provide
sufficient coverage. Any imposition of liability that our insurance does not
cover or exceeds our insurance coverage could materially adversely affect our
business, financial condition and operating results.
 
FUTURE SALES OF OUR COMMON STOCK MAY DEPRESS OUR STOCK PRICE
 
     The market price of our common stock could fall if our stockholders sell
substantial amounts of common stock, including shares issued upon the exercise
of outstanding options, in the public market following this offering. Such sales
might also make it more difficult for us to sell equity securities in the future
at a time and price that we deem appropriate. Please refer to our discussion in
"Shares Eligible for Future Sale."
 
OUR CORPORATE DOCUMENTS DISCOURAGE OUR ACQUISITION BY OTHERS
 
     Our corporate documents and Delaware law could make it more difficult for a
third party to acquire us, even if a change in control would be beneficial to
our stockholders. These and other provisions might discourage, delay or prevent
a change in control of us or of our management. These provisions could also
limit the price that investors might be willing to pay in the future for shares
of common stock. Please refer to our discussion in "Description of Capital
Stock."
 
                                       14
<PAGE>   19
 
AFTER THIS OFFERING, OUR OFFICERS AND DIRECTORS MAY STILL CONTROL US
 
     Our executive officers and directors will, in the aggregate, beneficially
own approximately      % of the common stock following this offering. These
stockholders may be able to exercise control over all matters that we require
our stockholders to approve, including electing directors and approving
significant corporate transactions. This concentration of ownership may also
have the effect of delaying or preventing a change in control of us, which could
result in a lower stock price.
 
THE PRICE FOR OUR COMMON STOCK IS LIKELY TO BE HIGHLY VOLATILE
 
     The market price of our common stock is likely to be highly volatile as the
stock market in general, and the market for Internet-related and technology
companies in particular, has been highly volatile. Investors may not be able to
resell their shares of our common stock following periods of volatility because
the market reacts adversely to volatility. The trading prices of many technology
and Internet-related companies' stocks reached historical highs within the last
52 weeks and reflect relative valuations that are substantially above historical
levels. During the same period, these companies' stocks have also recorded lows
well below historical highs. We cannot assure you that our stock will trade at
the same levels of other Internet stocks or that we can sustain our stock's
trading price and price/earnings ratio.
 
     Factors that could cause such volatility may include, among other things:
 
     - Actual or anticipated variations in our quarterly operating results;
 
     - If we or our competitors announce technological innovations;
 
     - If we launch new sales formats or new services;
 
     - If securities analysts change their financial estimates for us or our
       competitors;
 
     - Conditions or trends in the Internet industry;
 
     - If other Internet companies experience changes in their market
       valuations;
 
     - General conditions or trends in the stock market;
 
     - If we or our competitors announce significant acquisitions, strategic
       partnerships or joint ventures;
 
     - If we add or lose key personnel; and
 
     - If our stockholders sell common stock.
 
     Many of these factors are beyond our control. These factors may materially
adversely affect the market price of our common stock, regardless of how we
operate.
 
YOU WILL SUFFER IMMEDIATE AND SUBSTANTIAL DILUTION
 
     The initial public offering price per share will significantly exceed the
net tangible book value per share. Accordingly, investors purchasing shares in
this offering will suffer immediate and substantial dilution of their
investment.

                    FORWARD-LOOKING STATEMENTS; MARKET DATA
 
     We make many statements in this prospectus under the captions "Prospectus
Summary," "Risk Factors," "Management's Discussion and Analysis of Financial
Condition and Results of Operations," "Business," and elsewhere that are
forward-looking and are not based on historical facts. These statements relate
to our future plans, objectives, expectations and intentions. We may identify
these statements by the use of words such as "believes," "expects,"
"anticipates," "intends," "plans" and similar expressions. Because we make
forward-looking statements that involve risks and uncertainties, you need to
consider the important factors that could cause our actual results to differ
materially from those we express or imply in these forward-looking statements,
including those we discuss under "Risk Factors." Our actual results could differ
materially from those anticipated in these forward-looking statements as a
result of various factors, including those we discuss in "Risk Factors" and
elsewhere in this prospectus. The forward-looking statements speak only as of
the date of this prospectus and we caution you not to place undue reliance on
those statements.
 
     This prospectus contains market data related to us and the Internet. This
data has been included in the studies the Internet market research firms of
International Data Corporation, Jupiter Communications, Gartner Group, Forrester
Research, Electronic Mail and Messaging Systems, Creative Networks and
MediaMetrix publish. These market research firms assume certain events, trends
and activities will occur and they project information on those assumptions. If
the market research firms are wrong about any of their assumptions, then their
projections may also be wrong.

<PAGE>   21
 
                                USE OF PROCEEDS
 
     We estimate that we will receive approximately $     million in net
proceeds from this offering ($          if the underwriters' exercise their
over-allotment option in full) based upon an assumed initial public offering of
$     per share. This amount reflects deductions from the gross proceeds of the
offering of approximately $          for underwriting discounts and an estimated
$          for the expenses of this offering.
 
     We expect to use the net proceeds to:
 
     - Expand our sales and marketing efforts;
 
     - Hire additional personnel;
 
     - Repay outstanding borrowings under our revolving credit facility;
 
     - Fund our capital expenditures and product development; and
 
     - Fund working capital and for other general corporate purposes.
 
     In particular, we estimate that in 1999 we will use approximately $20
million of the net proceeds for equipment purchases and expansion of our data
centers. We also expect to use approximately $1.7 million of the net proceeds to
repay outstanding borrowings under our revolving credit facility. At March 31,
1999, borrowings outstanding under this facility were approximately $1.7
million. Borrowings under this credit facility bear interest at the bank's prime
rate, which was 7.75% at March 31, 1999. The amounts we actually expend in the
areas described above may vary significantly and will depend on a number of
factors, including our future revenue. Accordingly, management will retain broad
discretion in the allocation of the net proceeds of this offering. You will not
have the opportunity to evaluate the economic, financial or other information on
which we base our decisions on how to use the proceeds. A portion of the net
proceeds may also be used to acquire or invest in complimentary businesses,
technologies, services or products. We have no current plans, agreements or
commitments with respect to any such acquisition or investment, and we are not
currently engaged in any negotiations with respect to any such transaction.
 
     Pending such uses, the net proceeds of this offering will be invested in
short term, interest bearing, investment grade securities.
 
                                DIVIDEND POLICY
 
     We have never declared or paid any cash dividends on our capital stock. We
currently intend to retain any future earnings to finance the growth and
development of our business and therefore do not anticipate paying any cash
dividends in the foreseeable future. Any future determination to pay cash
dividends will be at the discretion of our board of directors and will depend
upon our financial condition, operating results, capital requirements and such
other factors as the board of directors deems relevant.

                                 CAPITALIZATION
 
     The following table sets forth our capitalization as of December 31, 1998.
Our capitalization is presented:
 
     - On an actual basis;
 
     - On a pro forma basis to reflect the automatic conversion of all
       outstanding shares of preferred stock into 5,536,871 shares of common
       stock at the same time as the closing of this offering; and
 
     - As adjusted to give effect to the sale of           shares of common
       stock offered in this offering at an assumed initial public offering
       price of $     per share (after deducting the estimated underwriting
       discounts and commissions and offering expenses) and the application of
       the net proceeds therefrom.
 
     This table should be read together with the financial statements and notes
to those statements appearing elsewhere in this prospectus.

     The number of shares of common stock to be outstanding after this offering
is based on the number of shares outstanding as of February 28, 1999. We are
permitted, and in some cases obligated, to issue shares of common stock in
addition to the common stock to be outstanding after this offering. The
following is a summary of these additional shares of common stock:
 
     - 802,250 shares that could be issued upon the exercise of options
       outstanding as of February 28, 1999 under our stock option plans, at a
       weighted average exercise price of $3.55 per share;
 
     - 425,763 additional shares that could be issued under our stock option
       plans;
 
     - 45,994 shares that could be issued upon exercise of an outstanding
       warrant at an exercise price of $14.75; and
 
     -           shares that can be issued to our employees who elect to buy
       stock in the future under our employee stock purchase plan.

                                    DILUTION
 
     Our pro forma net tangible book value as of December 31, 1998 was
$16,537,000, or approximately $2.72 per share. Pro forma net tangible book value
represents the amount of total tangible assets less total liabilities, divided
by the number of shares of common stock outstanding, assuming conversion of all
outstanding shares of preferred stock into common stock. Without taking into
account any other changes in the net tangible book value after December 31,
1998, other than to give effect to our receipt of the net proceeds from the sale
of the      shares of common stock in this offering at an assumed initial public
offering price of $     per share, our pro forma net tangible book value as of
December 31, 1998 would have been approximately $          , or $     per share.
This represents an immediate increase in net tangible book value of $     per
share to existing stockholders and an immediate dilution of $     per share to
new investors. The following table illustrates this per share dilution:

     The foregoing discussion and tables assume no exercise of the underwriters'
over-allotment option or of any outstanding stock options or warrants after
December 31, 1998. As of December 31, 1998, there were outstanding options to
purchase 831,400 shares of common stock at a weighted average exercise price of
$3.64 per share and a warrant to purchase 45,994 shares at an exercise price of
$14.75 per share. You will suffer further dilution to the extent any of these
options or this warrant is exercised.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     You should read the following discussion and analysis in conjunction with
"Selected Financial Data" and the financial statements and notes attached to
those statements included elsewhere in this prospectus. This discussion contains
certain forward-looking statements that involve risks and uncertainties. Please
see "Risk Factors" and "Forward-Looking Statements; Market Data" elsewhere in
this prospectus.
 
     We are a leading provider of email and advanced messaging solutions on the
Internet for consumers, Web portals and businesses. As of March 31, 1999, we
managed over 9.6 million mailboxes across all of our service offerings and
processed over 190 million messages during March 1999. Our consumer email
service, NET@DDRESS (www.netaddress.com), is the largest independent Web-based
email service on the Internet with more than 6.7 million mailboxes. Netscape and
register.com, a business-oriented portal site, constitute our primary Web portal
clients. Our commercial messaging solutions include specialized business
applications for companies such as American Express, as well as comprehensive
message outsourcing services for a wide range of businesses.
 
     We started our business in 1991 to provide online services, including
Internet access, to consumer and commercial customers. In 1995, we began the
development of our email solutions and in 1996 we launched NET@DDRESS, one of
the first Web-based email services available for consumers free of charge.
Before March 1997, we derived a significant portion of our revenue from the
Internet access business. In March 1997 we sold our Internet access business to
an entity in which certain of our stockholders hold an ownership interest. For
more information about that business, please refer to notes 3 and 9 in the notes
to the financial statements. We are treating our former Internet access business
as a discontinued operation. Since March 1997, our operating activities have
related primarily to planning and developing our advanced messaging solutions,
recruiting personnel, marketing our services, establishing operational
infrastructure, raising capital and purchasing technology infrastructure and
operating assets.
 
     We currently generate revenue from these services:
 
     - Messaging Services for Consumers. We generate revenue from NET@DDRESS by
       selling advertising and fee-based premium services.
 
     - Messaging Services for Web Portals and Businesses. We generate revenue
       from advertising sales, fee-based premium services and monthly
       per-mailbox fees. We share with Netscape and American Express a portion
       of our advertising and premium service revenue from Netscape WebMail and
       AmExMail.
 
     Our advertising revenue consists of the following:
 
     - Banners, Buttons and Log Out Pages. Banners, buttons and log out pages
       refer to the advertising we place on our Web-based email access sites. We
       charge different rates for the advertising we display on specific areas
       of the Web site.
 
     - Direct Delivery Content. We receive revenue for displaying advertising
       and promoting content subscription programs for third parties, such as
       news agencies, product information, etc.
 
     We typically sell banners, buttons and log out pages under short-term
contracts, which range from one week to one year in length. We also sell
longer-term and exclusive sponsorships, which combine banner advertisements,
button placements and log out pages. We typically guarantee minimum numbers of
impressions, or a stated number of times that an advertisement appears in pages
viewed by users of our email services, in our advertising agreements. If we fail
to supply the guaranteed number of impressions, our advertisers may terminate
their relationships with us. If, and to the extent that, we do not supply the
minimum guaranteed number of impressions, we recognize the corresponding revenue
only when we achieve the minimum guaranteed number. We recognize advertising
revenue as we display the advertising and we generally bill our advertisers on a
monthly basis.

     In June 1998, we launched our commercial messaging services. We sell our
commercial messaging services on a turnkey basis with a complete customer
service package, including both account management and technical support. Our
commercial messaging customers pay for mailboxes on a monthly basis and we
recognize revenue as we perform the services. We compensate our direct and third
party sales force primarily through commissions, a variable cost that we
determine based on a percentage of the gross revenue that the sales person
generates.
 
     Through December 31, 1998, we generated substantially all of our revenue
through advertising sales and less than 1% from our commercial messaging
services. We believe that our revenue mix will change as we generate more sales
from the services that we recently launched, including our specialized business
messaging solutions, message outsourcing solutions and fee-based premium
services. We anticipate that our mix of revenue from advertising may change in
the future as Internet advertising trends change and we develop new advertising
products. We expect that our gross margins may decrease for certain of our
co-branded services as the percentage of revenue that we share with certain of
our strategic partners increases over time. We also may spend significantly on
channel acquisition to ensure our position on strategic Web portals in the
future.
 
     To continue to execute our business plan, we intend to expand our
operations and employee base, including our sales, marketing, technical,
operational and customer support resources. We also intend to further develop
new and existing strategic relationships to expand our distribution channels. We
intend to develop strategic sales offices and data centers throughout the United
States. We plan to build an additional data center in 1999.
 
     We have incurred significant losses since our inception, and as of December
31, 1998 had an accumulated deficit of $28,571,068. Prior to March 1997, we were
an S corporation for tax purposes, and tax net operating losses prior to that
date are not available to offset any future taxable income. We intend to
continue to make investments in technology, which may involve the development,
acquisition or licensing of technologies that complement or augment our existing
services and technologies. We also intend to continue to invest heavily in sales
and marketing activities. We expect to incur significant operating losses for
the foreseeable future because of these aggressive expansion plans.
 
     In view of the rapidly evolving nature of our business and our limited
operating history, we believe that our revenue and operating results, including
our gross profit margin and operating expenses as a percentage of total revenue,
should not be relied upon as indications of future performance. We do not
believe that our historical growth rates are indicative of future results.
 
RESULTS OF CONTINUING OPERATIONS
 
  YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996
 
     Revenue. Revenue consists of advertising revenue and per-mailbox fees.
Revenue increased to $4,703,000 in 1998 from $782,000 in 1997 and $34,000 in
1996. Substantially all of these increases were due to increases in advertising
revenue. Since 1996, the increased number of users of our email and advanced
messaging solutions, our sales and marketing efforts, and the increased number
of advertisers allowed us to generate additional advertising revenue. The number
of NET@DDRESS mailboxes increased to 5.7 million at December 31, 1998 from 2.5
million at December 31, 1997 and 135,000 at December 31, 1996. Egghead.com
accounted for 27.0% of total revenue in 1998 and 18.1% of total revenue in 1997.
24/7 Media accounted for 14.9% of revenue and Webstakes accounted for 11.4% of
revenue in 1997.
 
     During 1998, we launched Netscape WebMail Powered by USA.NET. At December
31, 1998, Netscape WebMail had over 1.7 million mailboxes. Also in 1998,
together with American Express, we launched AmExMail Powered by USA.NET. At
December 31, 1998, AmExMail had over 214,000 mailboxes. We share with Netscape
and American Express a portion of the revenue that we generate under our
relationships with them. For 1998, the Netscape WebMail and AmExMail services
accounted for approximately 30.4% and 1.4% of revenue, respectively.

     Cost of Revenue. Cost of revenue consists primarily of Netscape's and
American Express' share of revenue that we generate under our relationships with
them, sales commissions, Internet connection charges, depreciation, salaries and
benefits of operating and customer service personnel, occupancy costs and other
related operating costs. Since 1996, the growth in the number of mailboxes we
manage has increased the cost of revenue. Cost of revenue increased to
$5,329,000 in 1998 from $1,614,000 in 1997 and $299,000 in 1996. During 1998,
these costs were approximately 113.3% of total revenue. Our cost of revenue
increased primarily due to increased personnel costs, depreciation expense and
sales commissions. We significantly increased the number of operations and
customer support personnel as follows:

December 31, 1996 .................................      6
</TABLE>
 
     In addition, we acquired substantial equipment for our data center
throughout 1998, and as a result, our depreciation expense increased in 1998.
 
     Selling and Marketing. Selling and marketing expenses consist primarily of
compensation for our sales and marketing personnel, advertising, and other
promotional costs. Selling and marketing expenses increased to $6,904,000 in
1998 from $2,269,000 in 1997 and $876,000 in 1996. The increases in 1998 and
1997 were primarily due to increases in the number of personnel as follows:

December 31, 1997 .................................      7
December 31, 1996 .................................      2
</TABLE>
 
     In addition, an increase in the purchase of Web-based advertising to
promote our services and an increased promotional effort for our commercial
messaging solution during 1998 contributed to the increase in selling and
marketing expenses.
 
     Product Development. Product development expenses consist primarily of
salaries and related benefits of development engineers, occupancy costs and
consulting fees. Product development expenses increased to $3,042,000 in 1998
from $1,208,000 in 1997 and $260,000 in 1996. The increase in product
development expenses in each year since 1996 is primarily due to ongoing costs
relating to the development of features and functionality of our current
consumer and commercial messaging solutions, as well as increases in the number
of product development personnel as follows:

     General and Administrative. General and administrative expenses include
salaries and related expenses for executives, finance personnel, corporate
support, as well as occupancy costs, professional fees and similar expenses.
General and administrative expenses increased to $2,447,000 in 1998 from
$1,490,000 in 1997 and $674,000 in 1996. The increase in each year since 1996 is
primarily due to the increased number of general and administrative personnel as
follows:

<PAGE>   28
 
     In addition, outside consulting, professional fees, recruiting fees and
travel expenses associated with our increased business activities added to the
increase in general and administrative expenses.
 
     Channel Acquisition Costs. During 1998, we paid Netscape $5,000,000 for the
exclusive right to provide email services to Netscape's domestic Netcenter
portal and $1,500,000 for similar international rights. Our policy on payments
to acquire channels to additional users is to capitalize them if the related
agreement provides minimum revenue guarantees that support the amount paid. The
agreements with Netscape do not provide minimum guarantees. As a result of this
and other factors, we expensed the payments to Netscape as channel acquisition
costs.
 
     Other Income. Other income consists primarily of interest earnings on our
cash, cash equivalents and short-term investments. We completed a private
placement of equity securities in August 1998, which provided net proceeds of
$21,390,000. During 1998, we also completed additional closings on prior private
placements, which provided proceeds of $10,835,000. As a result of these
closings, interest and other income increased to $521,000 in 1998 from $134,000
in 1997. Our other income in 1997 was primarily the result of interest income on
short-term investments.
 
     We have incurred interest expense on notes payable and capital lease
obligations. During 1998, interest expense was $230,000 compared to $9,000 for
1997. The increase in interest expense is due to our use of capital leases to
fund equipment purchases.
 
INCOME TAXES
 
     No provision or benefit for federal and state income taxes (actual or pro
forma) has been recorded because we incurred net operating losses from inception
through December 31, 1998. Prior to March 1997, we were an S corporation for tax
purposes. As of December 31, 1998 we had approximately $18,779,000 of federal
and state operating loss carryforwards available to offset future taxable income
which expire in varying amounts beginning in 2012. 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, including significant changes in
ownership interests. Our existing net operating loss carryforward may be
restricted due to changes in ownership or from future tax legislation.
 
     We have established a valuation allowance against the entire amount of our
deferred tax asset because our management has not been able to conclude that it
is more likely than not that we will be able to realize the deferred tax asset,
due primarily to our history of operating losses.

     Our revenue and cost of revenue during these periods closely tracked our
growth in users from quarter to quarter. Our operating expenses increased
quarter over quarter as we grew our sales and marketing capabilities, our
service offerings under development, and our administrative infrastructure.
Other factors that influenced our quarterly results in 1998 include the
following:
 
     - In April 1998 and November 1998, we paid Netscape channel acquisition
       costs, as discussed above;
 
     - In June 1998 we launched our commercial messaging services; and
 
     - In March 1998 and August 1998 we sold equity to investors.
 
     Our annual and quarterly operating results have fluctuated significantly in
the past and we expect them to fluctuate significantly in the future. Please
refer to our discussion in "Risk Factors" for a discussion of the factors that
may cause our quarterly results to fluctuate.

LIQUIDITY AND CAPITAL RESOURCES
 
     Our cash and cash equivalents, restricted cash and short-term investment
securities increased by $7,464,000 from December 31, 1997 to $11,508,000 at
December 31, 1998. This net change occurred because we raised $32,231,000 in net
proceeds from the sale of equity securities and incurred a net loss of
$19,228,000 during 1998 due to the expansion of our organization and operations.
Our investment in property and equipment during 1998 was $12,294,000, of which
$5,542,000 was financed with capital leases. Installation of network
infrastructure equipment in our data center, equipment for new employees and
leasehold improvements related to office and data center expansions accounted
for most of the increase in our capital expenditures in 1998. We expect that our
investment in property and equipment will continue to grow as we increase our
capacity to provide email services, although we have no formal commitments to do
so. We may also have to pay an additional $625,000 and $375,000 to Netscape in
1999 and 2000, respectively, subject to completion of certain tasks by Netscape.
 
     We have a credit facility with a bank that provides for borrowings up to
$2,000,000. As of December 31, 1998, $1,767,000 was outstanding under this
credit facility. Borrowings under this credit facility bear interest at the
bank's prime rate, which was 7.75% at December 31, 1998. Certain of our assets
collateralize borrowings under this facility and a stockholder that is an
officer and director has guaranteed the facility. Our capital lease obligations,
including both short-term and long-term portions, increased by $5,237,000 during
1998 (net of repayments) because we secured financing for a substantial share of
our additions to property and equipment.
 
     We have financed the majority of our operations through the issuance of
equity securities. We have sold common stock and preferred stock generating
aggregate net proceeds of $44,292,000, of which $1,487,000 was restricted at
December 31, 1998 for certain marketing and technical development efforts and is
reflected as restricted cash on our balance sheet.
 
     To date, we have derived substantially all of our revenue from the sale of
advertising on our Web sites. The Internet has not been available as an
advertising medium long enough to gauge its effectiveness as compared to
traditional advertising outlets. We may not be successful in marketing our
current services or other new or enhanced services. In addition, the market for
our services is characterized by rapid technological developments, frequent new
service introductions and evolving industry standards. These changes require us
to continually improve the performance, features, and reliability of our
services, particularly in response to competition. We may not be successful in
responding to these changes.
 
     We believe that the net proceeds from the sale of common stock offered
hereby, together with our current cash, cash equivalents and short-term
investment balances, cash generated from operations and cash available under our
credit facility, will be sufficient to meet our working capital and capital
expenditure requirements for at least the next 12 months. Our operating and
investing activities may require us to obtain additional equity or debt
financing. In addition, although there are no present understandings,
commitments or agreements with respect to any acquisition of other businesses,
products, and technologies, to consummate potential acquisitions, we may need
additional equity or debt financing in the future.
 
     We believe that capital is available to us from third parties if this
offering is not consummated. If this capital is not made available, a
stockholder has committed to fund our operations through 1999, if necessary.
 
YEAR 2000 ISSUES
 
     The Year 2000 issue arose because many computer programs were written using
two digits rather than four to define the applicable year. Any computer programs
or hardware that have date-sensitive software or embedded chips may recognize a
date using "00" as the year 1900 rather than the Year 2000. This could result in
system failures or miscalculations causing disruptions of operations for any
company using such computer programs or hardware, including, among other things,
an inability to connect to the
 
                                       26
<PAGE>   31
 
Internet, process transactions, send invoices or engage in normal business
activities. As a result, many companies must upgrade or replace their computer
systems to avoid "Year 2000" issues.
 
     We are a comparatively new enterprise, and, accordingly, the software and
hardware we use to manage our business has all been purchased or developed by us
within the last 24 months. While this fact pattern does not uniformly protect us
against Year 2000 exposure, we believe we gain some mitigation from the fact
that the IT we use to manage our business is not based upon "legacy" hardware
and software systems. "Legacy system" is a term often used to describe hardware
and software systems that were developed in previous decades when there was less
awareness of Year 2000 issues. Generally, hardware and software design within
the current decade and the past several years in particular has given greater
consideration to Year 2000 issues. All of the software code we have internally
developed to manage our network traffic, for example, is written with four
digits to define the applicable year.
 
     We are in the process of testing our internal IT and non-IT systems. We
have a dedicated Year 2000 project manager and our own personnel have performed
all of the testing we have completed. To date, we have completed testing of our
internally developed IT and non-IT software. Based on such testing, we believe
that such software is Year 2000 compliant.
 
     In addition to our internally developed software, we use software and
hardware developed by third parties both for our network and internal
information systems. We have not performed any testing of such third-party
software or hardware to determine Year 2000 compliance. We are, however, in the
process of obtaining certifications from our key vendors to ensure that their
hardware and software is Year 2000 compliant. Based on our initial evaluation of
our list of material software and hardware providers, we believe that these
providers are presently compliant or are reviewing and implementing their own
Year 2000 compliance programs. We intend to work with these providers to address
the Year 2000 issue and continue to seek assurances from them that their
products are Year 2000 compliant.
 
     In addition, we rely on third party network infrastructure providers to
gain access to the Internet. If such providers experience business interruptions
as a result of their failure to achieve Year 2000 compliance, our ability to
provide Internet connectivity could be impaired, which could have a material
adverse effect on our business, results of operations and financial condition.
 
     Our users' success in maintaining Year 2000 compliance is also significant
to our ability to generate revenue and execute our business plan. Interruptions
in our users' services and on-line activities caused by Year 2000 problems could
have a material adverse effect on our revenue.
 
     We have not incurred any significant expenses to date and we are not aware
of any material costs associated with our anticipated Year 2000 efforts.
However, if we, a significant number of our users, our providers of hardware and
software or our third-party network providers fail to remedy any Year 2000
issues, we could experience a material loss of revenue that could materially
adversely affect our business, results of operations and financial condition. We
would consider an interruption in our ability to provide our services to be the
most reasonably likely unfavorable result of any failure by us, or failure by
the third parties upon whom we rely, to achieve Year 2000 compliance. Presently,
we believe we are unable to reasonably estimate the duration and extent of any
such interruption, or quantify the effect it may have on our future revenue. We
have not yet developed a comprehensive contingency plan to address these issues,
which could result from such failure. We are prepared to develop such a
contingency plan if our ongoing assessment indicates areas of significant
exposure.
 
QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
     Market risk represents the risk of loss that may impact our financial
position, operating results or cash flows due to adverse changes in financial
and commodity market prices and rates. We are exposed to market risk in the
areas of changes in United States interest rates and changes in foreign currency
exchange rates as measured against the United States Dollar. These exposures are
directly related to our normal operating and funding activities. Historically
and as of December 31, 1998, we have not used derivative instruments or engaged
in hedging activities.

INTEREST RATE RISK
 
     The interest payable on our credit facility is variable based on the prime
rate, and, therefore, affected by changes in market interest rates. At December
31, 1998 and 1997, approximately $1,767,000 and $1,500,000 was outstanding on
the note payable. The note payable matures in January 2000. We manage interest
rate risk by investing excess funds in cash equivalents and short-term
investments bearing variable interest rates, which are tied to various market
indices. As a result, we do not believe that near-term changes in interest rates
will result in a material effect on our future earnings, fair values or cash
flows.
 
FOREIGN CURRENCY RISK
 
     We may enter into contracts where we pay or a third party pays us in a
foreign currency. This exposes us to changes in exchange rates. Changes in the
foreign exchange rates may positively or negatively affect our financial
position, results of operations or cash flows. We do not believe that near-term
changes in exchange rates will result in a material effect on future earnings,
fair values or cash flows, and therefore, have chosen not to enter into foreign
currency hedging instruments. There can be no assurance that such an approach
will be successful, especially in the event of a significant and sudden decline
in the foreign exchange rates.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
     In March 1998, the American Institute of Certified Public Accountants
issued Statement of Position ("SOP") No. 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use," which provides
guidance on accounting for the cost of such software. SOP No. 98-1 is effective
for financial statements for fiscal years beginning after December 15, 1998. The
Company does not expect that the adoption of SOP No. 98-1 will have a material
impact on its 1999 financial statements.
 
     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS No. 133"). The Company is required to
adopt SFAS No. 133 in the year ended December 31, 2000. SFAS No. 133 establishes
methods of accounting for derivative financial instruments and hedging
activities related to those instruments as well as other hedging activities. To
date, the Company has not entered into any derivative financial instruments or
hedging activities.

                                    BUSINESS
 
     We are a leading provider of email and advanced messaging solutions on the
Internet for consumers, Web portals and businesses. As of March 31, 1999, we
managed over 9.6 million mailboxes across all of our service offerings and
processed over 190 million messages during the month of March 1999. Our consumer
email service, NET@DDRESS (www.netaddress.com), is the largest independent
Web-based email service on the Internet with more than 6.7 million mailboxes.
Netscape and register.com, a business-oriented portal site, constitute our
primary Web portal clients. Our commercial messaging solutions include
specialized business applications for companies such as American Express, as
well as comprehensive message outsourcing services for a wide range of
businesses. We base our messaging solutions on highly reliable and scalable
technology that includes advanced features, universal accessibility and a high
level of security. We believe that our proven experience in meeting the rapidly
evolving messaging needs of consumers, Web portals and businesses positions us
to capitalize on the continuing rapid growth of Internet-based messaging.
 
  CONSUMERS
 
     In April 1996, we launched NET@DDRESS, the first Web-based email service
for consumers. NET@DDRESS, which we offer as a free service, has allowed us to
quickly build a large user base, establish our reputation for providing quality
service and scale-up our technology infrastructure. In 1998, NET@DDRESS won
awards for its superior features from PC Magazine, CNET and Windows Magazine. In
December 1998, MediaMetrix, an Internet usage measuring firm, ranked NET@DDRESS
as the sixth most popular site on the Web based on time spent online by Internet
users. We generate revenue from NET@DDRESS by selling advertising space and by
offering fee-based premium services. We intend to increase advertising revenue
from NET@DDRESS by using enhanced targeted marketing techniques and by expanding
our user base. We also plan to offer our users additional fee-based premium
services.
 
  WEB PORTALS
 
     We provide our messaging solutions to Web portals to enhance our reputation
as a premier provider of messaging services and to build our brand awareness
among both consumers and businesses. We host and manage the Web-based email
services for Netscape's Netcenter Web portal. Before we launched Netscape
WebMail Powered by USA.NET in July 1998, Netscape did not offer email capability
to its Netcenter members. Netscape WebMail currently has over 2.7 million
mailboxes. According to Netscape, in March 1999 there were approximately 14
million Netcenter members generating more than 50 million pageviews per day. In
September 1998, PC Magazine recognized Netscape WebMail as the top-ranked
Web-based email service in a review of the features of 12 major Web portals. We
are also developing foreign language-based email services for certain of
Netscape's international Netcenter Web portals. We generate revenue from
Netscape WebMail by selling advertising space through our internal sales force
and from fee-based premium services. We share this advertising and premium
service revenue with Netscape. Netscape invested in us in August 1998.
 
     In March 1999, we entered into an agreement with register.com to offer
businesses an integrated solution that combines our email and other advanced
messaging solutions with register.com's domain name registration service. We
plan to generate revenue by charging a monthly fee for each mailbox established
through this relationship.
 
  BUSINESSES
 
     We develop and deploy our application-specific messaging solutions to
address specialized business messaging needs. In April 1998, together with
American Express, we launched AmExMail, a Web-based email service that is
available to all consumers but which has special features available exclusively
for American Express Cardmembers. AmExMail enables American Express to
communicate with its customers and prospects in a variety of ways and helps
American Express build customer loyalty. American Express invested in us in
April 1997 and March 1998.
 
                                       29
<PAGE>   34
 
     We also offer comprehensive message outsourcing services to businesses to
meet their need for a cost-effective and reliable solution to their increasingly
complex messaging requirements. We introduced this service in June 1998 and
currently market it to companies in a wide range of industries, including
Internet service providers, wireline and wireless telecommunications companies,
publishers, information technology service companies, professional service
providers and consumer products companies.
 
     We generate revenue from these application-specific and comprehensive
outsourcing solutions primarily by charging a monthly fee for each mailbox. We
also offer fee-based premium services and sell advertising in select situations.
 
     We believe that we are well positioned to capitalize on the growing
importance of email as a communications medium for consumers, Web portals and
businesses. We believe that our messaging solutions will function as a central
message center that allows users to take advantage of the convergence of email,
voice mail and fax communications over the Internet. We believe that the
development of unified messaging will create new opportunities for expanded
services for a variety of Internet access devices, including computers, wireless
phones, pagers, personal digital assistants and television set-top boxes.
 
EMAIL AND MESSAGING BACKGROUND AND TRENDS
 
  GROWTH OF THE INTERNET AND INTERNET MESSAGING
 
     The Internet is quickly becoming an important communications tool,
advertising medium and sales channel for both consumers and businesses
worldwide. International Data Corporation estimates that the number of Internet
users worldwide will grow from 97 million in 1998 to 320 million by the end of
2002, and that the number of devices able to access the Internet will increase
from 120 million in 1998 to 515 million by the end of 2002. Jupiter
Communications estimates that online advertising revenue will grow from
approximately $1.9 billion in 1998 to approximately $7.7 billion in 2002.
 
     We believe that email and advanced messaging services will continue to be
key drivers of Internet usage and growth because they are among the most popular
Internet applications today. Email is a powerful yet inexpensive means of
handling a wide variety of business-to-business, business-to-consumer and
personal communications at any time and from any location. According to
Forrester Research, the number of email users in the United States is expected
to increase from 75 million in 1998 to 135 million in 2001. Electronic Mail and
Messaging Systems estimates that the total number of electronic mailboxes
worldwide will increase from approximately 326 million at the end of 1998 to
approximately 400 million at the end of 1999. In addition, Jupiter
Communications projects that the total number of email messages sent per day in
the United States will increase from 246 million in 1998 to 576 million in 2002.
We believe that the growth in the use of email is being driven by its
convenience, speed, relatively low cost and the ability to send multimedia
attachments, such as video clips, graphics files, audio files, documents and
spreadsheets.
 
  DEVELOPMENT OF INDUSTRY PROTOCOLS
 
     The creation and widespread acceptance of industry protocols have driven
the rapid growth in the use of the Internet as a messaging medium. The first
email protocols enabled users to send messages across a variety of computer
operating systems. Recently adopted Internet protocols facilitate a user's
access to messages from a variety of devices. New email solutions, including
those offered free of charge, allow users with a Web browser, such as Netscape
Navigator or Microsoft Internet Explorer, to access their messages from any
computer, terminal or kiosk that is connected to the Internet.
 
     Simple Mail Transport Protocol (SMTP) is currently the standard mail
protocol on the Internet. It allows Internet servers to route mail from the
sender to a destination. All Internet messages are transported using SMTP. Users
of proprietary email systems must convert their internal mail formats to SMTP
before sending messages over the Internet.
 
                                       30
<PAGE>   35
 
     Web-based mail allows users to access their messages from any computer or
device with a Web browser and Internet access. This eliminates the need to
maintain a separate program to access email. Post Office Protocol (POP) and
Internet Messaging Access Protocol (IMAP) are emerging standards that improve
the functionality of email. POP allows users to connect to a shared mail server
and download their mail to their computer or alternative Internet access device.
After a user downloads the mail, the user manages the mail on the user's
computer or device.
 
     IMAP provides greater flexibility at the server level than POP because IMAP
allows a user to sort messages, search for specific text in a message, and
manipulate folders and mailboxes while those files are still on the server host
instead of on the user's computer or alternative Internet access device. This is
particularly valuable for users who access their messages from different
computers with different email software. In addition, IMAP allows users to have
a common mailbox and customized folders and mailboxes that are not specific to a
particular computer or alternative access device.
 
  INTERNET MESSAGING CONVERGENCE
 
     Emerging Internet protocols, such as IMAP, are facilitating a convergence
in messaging. Today, businesses use multiple platforms to communicate by email,
voice mail and fax. These platforms generally use different technologies that
are based on different communications standards. The new Internet standards are
leading to the convergence of email, voice mail and fax communications onto a
single platform with a single standard. For example, these new standards will
allow voice mail messages to become audio attachments and faxes to become image
attachments to email messages. As a result, users will be able to read, view,
listen and respond to different message types using a common interface that can
be accessed by traditional personal computers or a variety of other Internet
connected devices, including wireless phones, network computers, pagers,
personal digital assistants and television set-top boxes.
 
     As email becomes an essential communications medium, businesses and
consumers expect their email service to be as reliable as their telephone
service. To remain competitive, businesses must be able to rapidly deploy an
advanced email system, manage the system effectively and increase its capacity.
As the number of email users grows and the volume and complexity of messages
increases, email systems must be able to accommodate increasing user demand and
rising storage requirements.
 
  SPECIALIZED BUSINESS APPLICATIONS AND MESSAGE OUTSOURCING SERVICES
 
     Today, many businesses have implemented in-house email systems which
require hardware, software and technical and administrative resources. Creative
Networks, an e-business consulting and research firm, estimates that to acquire,
deploy and operate an in-house messaging solution for 5,000 users, a business
must spend approximately $640 per user's mailbox per year. Even with this level
of investment, we believe many businesses still face significant downtime and
unreliable service. According to the Gartner Group, the percentage of large
businesses that expect to outsource at least some of their email systems is
estimated to grow from 10% in 1998 to 25% in 2000. Additionally, Forrester
Research estimates that the amount spent on outsourced email services will
increase from an estimated $8 million in 1997 to over $1 billion in 2002. We
believe that a growing number of businesses will outsource their messaging
services to ensure a more reliable, cost-effective and less resource-intensive
solution than their own in-house email system.
 
     The rapid proliferation in the number of email users, together with
advances in messaging technology, have enabled new applications for Internet
messaging such as enhanced customer care and service and targeted direct
marketing. However, many businesses lack the internal expertise or resources to
exploit these opportunities. We believe there is a significant need for a
provider of solutions for business communications needs.

     - Improve its ability to directly target promotional offers and other
       marketing initiatives to its customer base;

     - Attract and retain customers and increase customer satisfaction through
       ongoing communication and interaction on the Internet;
 
     - Differentiate itself from its competitors by offering new and enhanced
       services; and
 
     - Improve its business-to-business and business-to-consumer communication
       capabilities.
 
  EXPAND OUR MESSAGE OUTSOURCING SERVICES
 
     Our message outsourcing services are designed to address the needs of
businesses for cost-effective, reliable messaging solutions that can handle the
increasingly complex messaging requirements resulting from the convergence of
email, voice and fax communications. As a result, we are devoting significant
attention to expanding our message outsourcing services. We are pursuing this
opportunity by expanding our sales and marketing activities and by establishing
relationships with information technology service companies, resellers and
distributors which have access to a broad customer base. We also intend to focus
on developing strategic partnerships with selected telecommunications and other
service providers to bundle our commercial messaging services with their
communication services.
 
  CONTINUE LEADERSHIP IN CONSUMER MESSAGING
 
     We intend to continue to expand our NET@DDRESS user base and to increase
our average revenue per user. We plan to significantly expand our marketing
activities to broaden consumer awareness of NET@DDRESS and to attract mainstream
consumers, who are increasingly accessing the Internet and using email. We also
seek to increase our average revenue per user by enabling advertisers to pursue
targeted marketing initiatives and by offering fee-based premium services to
existing and new users.
 
  DEVELOP AND STRENGTHEN RELATIONSHIPS WITH WEB PORTALS
 
     We seek to maintain and expand our Netscape and register.com relationships
and to selectively pursue other Web portal relationships. We intend to generate
additional advertising and premium service revenue from Netscape's WebMail, and
we plan to broaden our per-mailbox revenue opportunities through our
relationship with register.com and other Web portals. We are focusing on
developing relationships with additional Web portals that we believe may further
build our reputation and provide us with access to significant user bases and
revenue opportunities.
 
  MAINTAIN TECHNOLOGY LEADERSHIP
 
     We have developed highly reliable and scalable messaging technology, and we
use the best available third party software where appropriate. We plan to
continue to be a leader in advanced messaging by combining the best available
third party hardware and software with our proprietary applications and
technology. We intend to:
 
     - Continue our focus on creating value-added solutions for specialized
       business applications;
 
     - Develop software to enhance our services; and
 
     - Ensure that our systems can be easily integrated with those of our users.

OUR ADVANCED MESSAGING SERVICES
 
     We have developed a wide range of reliable, easy-to-use advanced messaging
solutions to meet the rapidly evolving needs of consumers, Web portals and
businesses. We base our messaging solutions on highly reliable and scalable
technology that includes advanced features, universal accessibility and a high
level of security. We have multiple diverse revenue opportunities, including
advertising revenue, fee-based premium services and monthly per-mailbox fees.
 
  MESSAGING SOLUTIONS FOR CONSUMERS
 
     NET@DDRESS users receive a permanent email address of their choice with a
"usa.net" domain name (e.g. [email protected]). We provide the basic service free
of charge. The user's email address does not change regardless of how often the
user switches employers, schools or Internet service providers.
 
     NET@DDRESS users can send or retrieve email through the NET@DDRESS Web site
(www.netaddress.com) from any computer connected to the Internet with a standard
Web browser. Since NET@DDRESS is Web-based, users do not need to download or
install special software to access the service, but if they desire, they can
view their messages through popular software programs such as Netscape Messenger
or Microsoft Outlook.
 
     All NET@DDRESS users can use our robust set of free basic features to:
 
     - Store up to five megabytes of data;
 
     - Consolidate messages from multiple POP-compliant mailboxes into one
       mailbox;
 
     - Block unwanted messages;
 
     - Attach large, complex files to their messages;
 
     - Store frequently used email addresses in an address book;
 
     - Spell check messages;
 
     - Organize and archive messages in customized folders;
 
     - Add customized signatures to their messages; and
 
     - Create automatic replies to incoming messages.
 
     NET@DDRESS also offers advanced privacy and security features. Each user
has an account that the user can access only after entering a unique user name
and an individually selected password. Users accessing their accounts via a
public computer or other access device can choose to disable their memory cache,
meaning that viewed pages are expired rather than stored in the browser's memory
so that subsequent users of the public computer or other access device will not
be able to read the user's messages.
 
     NET@DDRESS users can also subscribe to several fee-based premium services,
including virus scanning, pager notification, email forwarding and POP access.
Users pay for these premium services on a monthly or annual basis.
 
     In return for providing basic messaging services free-of-charge, we place
advertising on the NET@DDRESS Web site. We generate revenue from these
advertising sales as well as from the promotion of opt-in content delivery,
which is marketing information and special offers from advertisers that users
can choose to receive. We gather demographic data during the initial
registration process, which we use for targeting advertisements and other
service offerings to users. We offer advertisers a number of programs to target
advertisements to various segments of our user base according to desired
demographic data to increase advertising effectiveness.
 
                                       34

  MESSAGING SOLUTIONS FOR WEB PORTALS
 
     Netscape WebMail Powered by USA.NET
 
     In 1998, we entered into a relationship with Netscape to host and manage
email services for Netscape's Netcenter Web portal. Netscape WebMail Powered by
USA.NET is accessible from the Netscape Netcenter Web site (www.netcenter.com)
as well as from a button on the toolbar of Netscape browser software. The email
service offers the same features and functionality as our NET@DDRESS service. We
host the email services at our facilities. Netscape WebMail users are also
automatically enrolled as Netcenter members.
 
     According to Netscape, Netscape WebMail Powered by USA.NET has become the
leading source of attracting new members to Netcenter. We believe that hosting
the Netscape WebMail service has provided us with high visibility and has
significantly helped us build brand awareness. We intend to market our
commercial messaging services to the business users that frequent the Netscape
Netcenter site.
 
     Our agreement with Netscape provides us with multiple revenue
opportunities, including advertising and additional fee-based premium services
similar to those offered by NET@DDRESS users. We are responsible for selling all
advertising space on Netscape WebMail Powered by USA.NET. We share advertising
and premium service revenue with Netscape. We recently expanded the scope of our
agreement with Netscape to develop foreign language-based email services for
certain of Netscape's international Netcenter Web portals. We also expect to
generate revenue on the international Web portals by selling advertising space
and fee-based premium services.
 
     Strategic Partnership with register.com
 
     In March 1999, we entered into an agreement with register.com, a business
portal site that is the largest single domain name registration service on the
Internet. We believe that the first two steps for a business to establish a
presence on the Internet are to register for a domain name and establish email
service. Together with register.com, we expect to provide businesses with a
bundled offering of domain name registration and business messaging services.
 
     Under the terms of our agreement, register.com offers its customers the
opportunity to receive a Web-based email account with the customer's new domain
name. We plan to generate revenue from this relationship by charging a monthly
per-mailbox fee.
 
  MESSAGING SOLUTIONS FOR BUSINESSES
 
     Specialized Messaging Application for American Express
 
     In April 1998, together with American Express, we launched AmExMail Powered
by USA.NET (www.amexmail.com). As of March 31, 1999, AmExMail had over 258,000
mailboxes. The AmExMail service is offered free to all consumers with all of the
features and functionality of our NET@DDRESS service. American Express'
Cardmembers, however, receive without charge certain services and features that
other users must pay for, including POP access and message management features.
 
     We host the AmExMail services on secure servers located at our facilities.
We generate revenue from the AmExMail service from advertisements. We also plan
to offer fee-based premium services to AmExMail users. We share advertising and
premium service revenue from AmExMail with American Express.
 
     Other Specialized Messaging Applications
 
     We plan to develop other specialized messaging applications that address
business needs and to develop value-added solutions that can be integrated with
other technologies to address unique communications needs. We believe that
businesses can apply these solutions to increase customer service quality,
enhance their products and services, interact directly with their customer base,
employ direct
                                       35
<PAGE>   40
 
marketing techniques and increase customer loyalty. Some of the specialized
applications that we are currently developing include solutions for:
 
     - Universities and other groups to establish affinity programs with their
       alumni or membership base;
 
     - Telecommunications and wireless service providers to bundle our messaging
       solutions with their telecommunications services; and
 
     - Internet service providers and Web hosting companies to combine our
       services with theirs and provide a complete communications package for
       their customers.
 
     Message Outsourcing Services
 
     We launched our commercial message outsourcing service in June 1998. This
service is a cost-effective, easy-to-use email service that is scalable as a
customer's business grows. We sell this service on a turnkey basis with a
complete customer service package, including both account management and
technical support. We currently sell our commercial messaging services directly
through our sales force and indirectly through sales channel partners, such as
information technology service companies and Internet service providers. We are
also pursuing relationships with resellers and distributors aggressively. We
charge a monthly per-mailbox fee that allows a business to avoid expensive
up-front capital expenditures and to scale its spending as its business grows.
We believe that we may have additional revenue opportunities through the sale of
premium services and advertising space in select situations. We manage these
services at our data center, which is monitored by our team of trained systems
operations professionals seven days a week, twenty-four hours per day.
 
     When a business signs up for the commercial messaging services, it
designates a domain name and selects an initial number of mailboxes. The
business also designates one of its employees as a "postmaster" to
self-administer email addresses, customize the client's email interfaces and add
and delete users when appropriate. We train the postmaster and provide ongoing
customer support.
 
     We designed our commercial messaging services to complement and enhance a
business' existing email software. Our commercial messaging services can
streamline a business' messaging functions because it can integrate disparate
email systems that a business may have in different office locations. These
services also permit businesses to standardize their email services using any
email software, such as Netscape Messenger or Microsoft Outlook. As a result,
our services can be implemented easily and with minimal impact on business
operations. We also designed our commercial messaging services to grow so that
businesses can manage increasing volumes of messages in a cost-effective manner.
 
     Our commercial messaging services can also add new features and
functionality to a business' existing system. For example, we provide gateway
filtering for virus detection, filtering for unwanted junk email, and email
certification and encryption. In addition, because our service is Web-based,
users can access their messages from any Internet-connected device with a Web
browser at any time from any location.
 
     A business can also customize its email for a professional "look and feel"

     The descriptions in this prospectus regarding our planned service offerings
and the anticipated features of those planned service offerings are
forward-looking statements. Actual services and features could differ materially
from those projected as a result of a variety of factors, some or all of which
may be out of our control. Please refer to "Risk Factors."
 
  CLASSES OF SERVICE
 
     We offer classes of our email services designed to address the specific
needs of businesses and consumers. The classes of services reflect different
combinations of our premium features with our basic services. For example, a
NET@DDRESS user may only need Web access, while a Web portal might want IMAP and
POP access and a business might want all of these services plus encryption.
 
ADVERTISING SALES AND PROGRAMS
 
     Advertising plays an important role in the business models for NET@DDRESS,
Netscape WebMail Powered by USA.NET and AmExMail Powered by USA.NET. We gather
demographic data on each user who registers for these services. Advertisers can
take advantage of our sophisticated targeted advertising and direct marketing
capabilities on each of these services. We work closely with our advertising and
sponsorship partners to monitor the effectiveness of their advertisements on our
sites and to develop customized solutions to best meet our advertisers' and
sponsorship partners' needs. We believe that our use of sophisticated targeted
marketing tools is critical to our ability to sell our advertising space on the
Internet.
 
     We sell a variety of advertising and sponsorship options to our clients. In
addition to providing banner and button advertising, we specialize in selling
innovative advertising packages to our advertisers at higher rates. Such
programs include:
 
     - Direct Delivery Programs. We promote content from our direct delivery
      providers on our services. Users choose to receive content from categories
      such as news, sports, entertainment and special offers that meet their
      specific interests. Our direct delivery providers in March 1999 included
      iVillage, Launch, Sports Illustrated and US News and World Report.
 
     - Logout Page Redirects. When a user logs out of an email session, we
       automatically link that user to the advertiser's Web site where the user
       can further explore the advertiser's product and service offerings.
 
     - E-direct Programs. We target promotional offers to users that have
       "opted-in" and indicated an interest in receiving promotions and special
       offers.
 
     Generally, banner advertising is purchased on a price-per-impression basis.
We also receive advertising revenue through fixed fees from content providers,
fees charged in connection with bundling a sponsorship package and bounty fees
we receive when a user signs up for an advertiser's or sponsor's service.
 
     We sell advertisements to companies and organizations from a broad range of
markets, including online services, telecommunications, publishing, online
retailing and consumer goods and services. Following is a list of our top
advertisers during the twelve months ended March 31, 1999:

     Egghead.com accounted for 27.0% of total revenue in 1998 and 18.1% of total
revenue in 1997. 24/7 Media accounted for 14.9% of revenue and Webstakes
accounted for 11.4% of revenue in 1997. We have an internal advertising sales
staff of five professionals. We compensate our sales staff primarily through
sales commissions. We currently sell our entire advertising inventory through
our internal sales staff, allowing us to better control pricing and inventory,
maintain brand consistency and capture maximum revenue.
 
MARKETING STRATEGY AND EXECUTION
 
     Our marketing objective is to establish ourselves as the leading provider
of advanced messaging services by building brand awareness and developing a
strong core of strategic relationships and partners and a large, loyal user
base. We base our strategy for achieving these objectives on an integrated set
of marketing initiatives, including public relations programs and generating
targeted sales leads.
 
  CONSUMER MESSAGING
 
     Our marketing strategy for NET@DDRESS includes:
 
     - Building awareness of NET@DDRESS through public relations activities and
       banners;
 
     - Acquiring users through word of mouth, banner ads and co-marketing
       programs;
 
     - Driving use of our services through welcome page communications, new
       features, direct delivery of content and value-added services; and
 
     - Building loyalty through retention programs, newsletters and superior
       customer service.
 
     To execute this strategy, we buy advertising on leading Internet sites and
in other media. In addition, we offer bounty programs to leading Web sites, in
which we pay the Web sites for each new NET@DDRESS mailbox that the Web site
obtains for us. We also have an ongoing public relations campaign that we target
to consumers, potential advertisers and the financial and business community. We
also have co-marketing programs with strategic partners. Our marketing strategy
includes using the NET@DDRESS Web site welcome page to deliver sponsorships for
advertisers, while offering users content and special offers on products and
services. We intend to increase our marketing efforts for NET@DDRESS at targeted
audiences, such as students, business executives and travelers. In addition, we
plan to expand use of NET@DDRESS and build brand loyalty through the marketing
and distribution of enhanced email service features.
 
  WEB PORTAL AND BUSINESS MESSAGING
 
     Our marketing strategy for Netscape WebMail Powered by USA.NET is to build
awareness of our service primarily by gaining exposure to visitors to the
Netcenter site and by leveraging Netscape's public relations campaigns. We
intend to continue working with Netscape to optimize the use of Netscape WebMail
as a customer distribution channel for Netscape. We also plan to explore
opportunities to expand our relationship with Netscape to target other potential
commercial messaging service users.
 
     We plan to continue to build awareness of the AmExMail services through
advertising online, including through Web site links, and on other media, such
as newsletters, flyers and mailers. We are also working with American Express to
identify additional opportunities to provide other exclusive services on
AmExMail and to develop special services and specific marketing programs, such
as Membership Rewards.
 
     Our marketing strategy for our other Web portal and business messaging
services is to:
 
     - Develop sales leads through direct contacts, channel partner
       opportunities, direct mail, print advertising and online advertising;
 
                                       42
<PAGE>   47
 
     - Leverage co-marketing opportunities for our advanced messaging services
       with selected Web portals, such as register.com;
 
     - Advertise in publications directed at specific industries, professional
       and trade associations, and targeted partner channels;
 
     - Seek strategic partnerships with selected telecommunications, Internet
       and other service providers to bundle our advanced messaging services
       with their services; and
 
     - Leverage our existing brand awareness developed from managing over 9.6
       million mailboxes across all of our service offerings.
 
     We also intend to identify unique messaging needs of businesses and to
develop and market specialized applications to address them. We believe that we
can leverage our advanced messaging technology by developing and marketing
value-added solutions to specific business needs such as targeted direct
marketing, customer care, business-to-business communications and affinity
programs.
 
     In order to maximize our penetration of these potential markets, we plan to
market our solutions through our direct sales force as well as through third
party resellers and distributors who can offer bundled service offerings or can
co-market our services in connection with their core business.
 
CUSTOMER SERVICE
 
     Offering our customers a high level of customer service and technical
support is a top priority of ours and we believe that it is critical to our
success. We believe that the quality of our customer service distinguishes us
from our competitors. Our customer service staff consists of customer service
representatives, technical support specialists, account coordinators, quality
assurance analysts, order processors and our management. As of March 31, 1999,
we employed 41 people in this group.
 
     Our customer service representatives, account coordinators and technical
support specialists are trained, experienced service professionals. Our customer
service representatives provide multifunctional end-user support across all of
our consumer and commercial messaging services. Our account coordinators and
dedicated customer support representatives provide support, training, account
set-up and provisioning for our business accounts. Our technical support
specialists use e-service tools to categorize, trouble-shoot, and resolve
escalated end-user inquiries or "trouble tickets." We staff our call center
seven days per week, twelve hours per day. We provide additional customer
support seven days per week, twenty-four hours per day, by contractual
arrangement.
 
     We provide full-service customer support through voice, e-service and
interactive online end user support. We use third party, interactive e-service
technology to resolve most of our end-user inquiries within our Web site. We
also provide a "frequently asked questions" section, online knowledge-based
self-help and interactive e-service inquiry tools on our Web site. We make
available traditional toll or toll-free live agent telephone support to some
businesses by contract. We also contract with a third party to provide
multi-lingual interactive on-line support.
 
     In an effort to further improve customer satisfaction, we regularly
evaluate the latest customer support technology and tools. We also track
recurring customer issues to identify opportunities for us to improve our
services.
 
NETWORK AND TECHNOLOGY
 
     We base all of our services on highly reliable and scalable technology that
includes advanced features, universal accessibility and a high level of
security.
 
     Our messaging network is designed to take advantage of the approaching
convergence of email, voice mail and fax communications. Since we base our
infrastructure on standard Internet protocols, our services can be readily
expanded to enable multiple kinds of messaging with many types of devices and
software.
 
                                       43
<PAGE>   48
 
We plan to combine the best available third party hardware and software with our
proprietary applications and technology to provide reliable, easy-to-use and
versatile email and other advanced messaging services.
 
     We use leading hardware and software solutions, such as Cisco Systems
routers, EMC storage devices, Oracle database software and Sun Microsystems
servers. We plan to continue to leverage high quality services and technologies
to enhance the design and performance of our messaging networks.
 
     Our experience in handling massive volumes of messages and Internet
requests through our email engine technology has allowed us to refine our
scalable email messaging solutions. We designed our email engine components to
be independently scalable, allowing the addition of hardware and software units
as we approach capacity thresholds. We provide a true, distributed and scalable
Internet email messaging architecture. Each hardware and software process within
our network has "fail-over" protections to provide complete service redundancy.
We designed our network for maximum service availability, including load-
balanced message routing and queuing, peering (or multiple public and private
Internet network connections) and redundant interconnection.
 
     We have a robust, tiered, stand-alone testing environment that has the same
hardware and layered products as our production environment. We have separate
integration and production test environments to isolate our system so that we
can do the functional and performance testing that is essential for us to
deliver "carrier grade" messaging services. We partition our testing environment
so that we can simultaneously test multiple scenarios across our services and
protocols. As a result of this increased efficiency we can provide our users
with robust services that have fewer defects and we can achieve internal cost
savings.
 
     Our proprietary messaging technology streamlines incoming and outgoing
message traffic, message filtering and Web-based email client requests. We
receive each request type through our proprietary queuing and look-up process,
which examines a local cache of recent requests and then gathers the results
from the appropriate cache or appropriate database. We deliver the request
through a corresponding Internet protocol, such as SMTP, POP or IMAP.
 
     Our robust network infrastructure provides our customers with diverse, high
bandwidth connectivity between the Internet and our facilities. We currently
have agreements in place with Qwest, AT&T, MCI WorldCom (via UUNET) and e.spire
for high capacity OC-3 and DS3 level service. We are not dependent on any
co-location facilities. Through these agreements we have direct, private
connections to most major Internet backbone providers. These connections,
together with the number of bandwidth providers with which we have primary
agreements, provides our users with a significant level of both diversity and
redundancy in their email services Internet connection.
 
     We manage this Internet backbone connectivity at our facilities through
redundant Cisco Systems routers using Hot Standby Routing Protocol (HSRP).
Failure of any given network component, circuit or provider should have minimal
impact on the performance of our services for our users. All nodes within our
facilities operate on full 100 megabytes switched Ethernet in a collapsed
backbone configuration for optimal switching efficiency. We trunk our switches
at 1 gigabyte to provide high performance interconnectivity between our Virtual
Local Area Network (VLAN) environments. Finally, our computing facilities are
separated from the public networks through multiple firewalls provided through
Cisco Systems and Sun Microsystems technologies.
 
     Our messaging data center, located in Colorado Springs, is connected
through these diverse network providers to multiple high-performance, high
bandwidth providers that carry all email messaging and Internet traffic. One of
the advantages of our Colorado Springs data center site is its location halfway
between London and Tokyo and its relative lack of susceptibility to major
natural disasters. Our data center is supported by redundant server and network
hardware to achieve carrier-grade uptime and performance. We protect our
physical assets within the data center with video surveillance, twenty-four
hours a day, seven days a week staffing and monitoring, automated fire
suppression and secure badges. We protect our intellectual property and our user
data with two layers of firewall technology combined with an encrypted access
system and individual component access tracking.
 
                                       44
<PAGE>   49
 
     We currently manage more than 19 terabytes of customer data in our data
center. We expect to deploy an additional 15 terabytes of storage capacity in
late 1999. All of our databases are stored on high-speed EMC disk arrays, are
three-way, RAID 1 mirrored and have business continuance volumes configured to
maximize reliability and performance. Our databases are automatically backed up
on a nightly basis to a tape library. We rotate tapes offsite on a regular basis
and store them in a fireproof safe.
 
     We are expanding our existing data center and increasing our available
floor space to better support our growing base of users. We also expect to open
an additional data center in 1999. This center will increase our available space
by a factor of five and further increase our level of redundancy and our ability
to serve our customer base. As we expand our services internationally, we intend
to open data centers in Europe and Asia. These data centers would add further
redundancy and improve local connectivity in those markets.
 
     Unsolicited bulk mail, or spam, is a significant problem for email service
providers. All of our email services include integrated spam blocking features.
We have developed proprietary technology and implemented procedures for
detecting and blocking spam twenty-four hours a day, seven days a week. We have
also designed systems to detect and terminate mailbox accounts that engage in
spam activity.
 
COMPETITION
 
     Competition in the advanced messaging services industry is intense and we
expect competition to persist, intensify and increase in the future. The market
for selling advertising space on the Internet is also very competitive.
 
     Our consumer email service primarily competes against Hotmail (a service of
Microsoft). In addition, we compete against Web portal sites that have email
services, such as Yahoo!, Excite, Lycos and AltaVista. We also compete against
independent email providers, such as Juno Online Services and Mail.com.
 
     Our NET@DDRESS service also competes against Internet service providers,
such as America Online, who include portable email address solutions within
their basic service offerings. A number of companies offering Internet products
and services recently have begun to integrate Web-based email within the
products and services they offer to consumers and businesses. Other vertical
market portal sites and affinity groups also offer or may in the future offer
email services to their users.
 
     There are a growing number of companies offering various consumer and
commercial email outsourcing services. In the consumer outsourcing market,
companies such as Mail.com, CommTouch and Lycos provide outsourcing for consumer
applications. In addition, entities that provide an initial point of entry for
Internet users, such as the Regional Bell Operating Companies, AT&T and IBM, can
be expected to consider further development, acquisition or licensing of
Web-based email functions and services competitive with our services.
 
     Commercial outsourcing competition consists of companies offering services
to businesses and service providers. Competitors in this market include, or are
expected to include, Critical Path, CompuServe and PSINet. In addition, we
expect that other companies, particularly large service providers,
telecommunications companies and data outsourcing companies, such as EDS and
Computer Sciences, will begin to offer solutions in commercial outsourcing in
the relatively near term.
 
     Our ability to compete depends on many factors, many of which are outside
of our control. We believe the primary competitive factors determining success
in our markets are the following:
 
     - Service quality and reliability;
 
     - Price;
 
     - Feature sets;
 
     - Customer support;
 
                                       45
<PAGE>   50
 
     - Ease-of-use of products and services;
 
     - Our ability to anticipate and adapt to a developing market and rapidly
       changing technologies;
 
     - The sales and marketing efforts of us and our competitors;
 
     - The timing and introduction of new products and services; and
 
     - General industry and economic conditions.
 
     In selling advertising space, we compete with many of the market
participants listed above, as well as with various advertising-supported Web
sites, including portal sites such as Yahoo! and Excite, content sites such as
CNET and CNN.com and interactive advertising networks and agencies such as
DoubleClick and 24/7 Media. We also compete with traditional media such as print
and television for a share of our advertisers' total advertising budgets. If
advertisers perceive the Internet to be a limited or ineffective advertising
medium or perceive us to be less effective or less desirable than other Internet
advertising vehicles, advertisers may be reluctant to advertise on our services.
To compete for Internet advertisers, we must offer effective methods of
targeting subscribers with demographic characteristics attractive to these
advertisers.
 
STRATEGIC RELATIONSHIPS
 
     We enter into strategic relationships to build our reputation as a premier
provider of advanced messaging services, to build our brand awareness and to
sell application-specific messaging solutions that address specialized industry
messaging needs. We have entered into the following alliances:
 
  AMERICAN EXPRESS
 
     In April 1997, we entered into a two-year renewable co-marketing and
program agreement with American Express, a global travel, financial and network
services provider, to build and operate AmExMail Powered by USA.NET. In December
1998, we extended the agreement by four months and it now expires July 8, 1999.
If the agreement expires or terminates, American Express would need to find an
alternate email service and we would forward the AmExMail users' email to the
new service. American Express would pay us a fee for forwarding the mail.
 
     Under our agreement with American Express we have agreed not to administer
or directly offer email or similar services on behalf of or in conjunction with
any competitor of American Express without their consent. A competitor of
American Express includes any charge, credit or debit card business, financial
services business or travel agency business.
 
     In April 1997 and March 1998, American Express purchased an aggregate of
883,652 shares of preferred stock (which will convert into 883,652 shares of
common stock on the closing of this offering).
 
  NETSCAPE
 
     In April 1998, we entered into a two-year, renewable services agreement
with Netscape, a leading provider of open software for linking people and
information over enterprise networks and the Internet, to build and operate
Netscape WebMail Powered by USA.NET. In October 1998, we extended the agreement
to include a two-year renewable services agreement for certain of Netscape's
international Netcenter Web portals, for which we are developing foreign
language-based email services. On expiration or termination of the agreement, we
can market replacement email services to the Netscape WebMail users if we
contact them other than through the information we obtain from their
registration with Netscape WebMail.
 
     We have agreed not to display on WebMail any advertisements or other
promotional text or graphics for third party products or services that are
directly competitive with Netscape's software products and online services.
 
                                       46
<PAGE>   51
 
     Netscape purchased 67,797 shares of preferred stock (which will convert
into 67,797 shares of common stock on the closing of this offering) in August
1998.
 
  REGISTER.COM
 
     In March 1999, we entered into a one-year, renewable reseller agreement
with register.com, a business portal site which is the largest single domain
name registration service on the Internet. register.com will offer its customers
the opportunity to receive a Web-based email account for each employee that
contains the business' domain name, such as [email protected]. This
service allows businesses to have a company-branded domain name for all of its
employees and to outsource its business messaging needs through our commercial
messaging services. register.com is responsible for all billing and collection
from its customers. If our agreement with register.com expires or terminates, we
can acquire all of the mailbox customers by paying register.com a one-time fee.
 
     We have agreed to promote register.com as the exclusive domain name
registration service for our email messaging services, subject to certain
exceptions. Similarly, register.com has agreed not to promote or sell
competitive email messaging services.
 
  PREMIERE TECHNOLOGIES
 
     In October 1997, we entered into a two-year, renewable co-marketing and
integration agreement with Premiere Technologies, a public company that provides
enhanced communications management services, including unified messaging
(integrated email, fax and voice messaging and conference calling managed from
either a Web or telephone interface), networked voice messaging, electronic
document distribution (email and fax) and conference calling and enhanced
calling card services. We are working with Premiere to develop enhanced features
for our email services. We are also working on a co-marketing plan to market
each other's services. We intend to generate revenue from the sale of
co-developed premium services on our email services. We will share revenue from
our co-developed premium services with Premiere.
 
     In October 1997 and March 1998, Premiere purchased an aggregate of 883,652
shares of preferred stock (which will convert into 883,652 shares of common
stock on the closing of this offering).
 
     Under our agreement with Premiere, we have agreed to use Premiere as our
exclusive provider of mobile telecommunications services, including calling
card, text-to-speech email, conference calling and Web-based conference calling,
as well as fax services, including email-to-fax, pager or voice notification of
messages and services.
 
INTELLECTUAL PROPERTY
 
     Trademarks, service marks, trade secrets, copyrights and other proprietary
rights are important to our success and competitive position. We have registered
and applied for registration of certain service marks and trademarks with the
appropriate state and federal agencies, and will continue to evaluate the
registration of additional service marks and trademarks, as appropriate. We have
one allowed United States patent. We may not gain any competitive advantages
from any patents or be able to exploit them profitably. Further, any patents may
not be able to withstand challenges from third parties.
 
     We seek to protect our proprietary rights, but our efforts may be
inadequate. Existing trade secret, copyright, patent and trademark laws offer
only limited protection. Further, effective trade secret, copyright, patent and
trademark protection may not be available in every country in which we make our
services available through the Internet, and policing unauthorized use of our
proprietary information is difficult. The unauthorized misappropriation of our
proprietary technology could have a material adverse effect on our business,
financial condition and operating results. If we resort to legal proceedings to
enforce our proprietary rights, the proceedings could be burdensome and
expensive and could involve a high degree of risk.
 
                                       47
<PAGE>   52
 
     We may also be subject to claims alleging that we have infringed third
party proprietary rights. If we were to discover that any of our services
infringed third party rights, we may not be able to obtain permission to use
those rights on commercially reasonable terms. This may require us to expend
significant resources to make our services non-infringing or to discontinue the
use of our services. We might incur substantial costs defending against an
infringement claim, even if the claim is invalid. If we have to defend against
an infringement claim it could distract our management from our business.
Further, a party making a claim could secure a judgment that requires us to pay
substantial damages or that prevents us from using or selling our products and
services. Any of these events could have a material adverse effect on our
business, financial condition and operating results. Our success depends
significantly upon our proprietary technology, including our advanced email
technology.
 
GOVERNMENTAL REGULATION
 
     We are subject to laws and regulations that are applied to various Internet
activities. There are many legislative and regulatory proposals under
consideration by federal, state, local and foreign governments and agencies,
including matters related to:
 
     - Online content;
 
     - User privacy;
 
     - Access charges;
 
     - Jurisdiction;
 
     - International, federal, state and local taxation;
 
     - Liability for third party actions;
 
     - Intellectual property; and
 
     - Characteristics and quality of products and services.
 
     Legislation in these areas could impair the growth of the Internet and
decrease the acceptance of the Internet as a communications and commercial
medium. This could decrease the demand for our services, increase our cost of
doing business or otherwise have a material adverse affect on our business,
financial condition and operating results.
 
     Further, the growth and development of the market for Internet email may
prompt calls for more stringent consumer protection laws that may impose
additional burdens on companies conducting business online. For example, any
laws or regulations that restrict our ability to collect or use personal data
from our users to target advertisements may adversely affect us. There have also
been numerous legislative initiatives proposed to address the prevalence of spam
email on the Internet. These laws may impose additional burdens on our business.
 
     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 new legislation or regulation regarding the Internet, or the
application of existing laws and regulations to the Internet, could harm our
business. Additionally, because we expect to expand our operations outside of
the United States, the international regulatory environment relating to the
Internet could have a material adverse effect on our business.
 
EMPLOYEES
 
     As of March 31, 1999, we employed 180 people, all of whom are full-time.
The 180 employees include 24 in general and administrative functions, 64 in
operations functions, 48 in sales and marketing and 44 in product development.
We outsource our human resources operations to The Personnel

Department, a privately-held company. Our employees are not represented by a
labor union or covered by any collective bargaining agreements. We consider our
employee relations to be good.
 
FACILITIES
 
     Our principal offices are located in over 21,000 square feet of space in
Colorado Springs, Colorado, under a lease expiring on October 31, 2002. We lease
two other facilities in Colorado Springs, one with over 4,000 square feet that
houses our data center and one with over 19,000 square feet that is primarily
used by our information technology staff. We lease additional office space in
Denver, Colorado, San Francisco, California and New York, New York. We believe
that our current facilities and the data center we plan to open in 1999 will be
adequate for our needs for at least the next twelve months.
 
LEGAL PROCEEDINGS
 
     From time to time, we are subject to legal proceedings arising out of our
operations. We are not currently a party to any material legal proceedings.

DIRECTORS' TERMS
 
     We currently have five authorized directors. In March 1999, the board of
directors approved, subject to stockholder approval, the amendment of our
certificate of incorporation to provide for the division of the board of
directors into three classes, with only one class standing for election each
year. At each annual meeting, directors are chosen to succeed those in the class
whose term expires at that meeting and to serve for a term of three years. Under
this provision, Mr. Street serves as a class I director, Mr. Allred and Ms.
Griffith Gryga serve as class II directors, and Ms. Beazley and Mr. Sharnak
serve as class III directors, with terms of office scheduled to expire at our
2000, 2001 and 2002 annual meetings of stockholders.
 
     Our current certificate of incorporation provides for the designation of
one member of the board of directors by the holders of the company's preferred
stock (currently, Ms. Griffith Gryga), the designation of one member of the
board of directors by the holders of the company's Series A Preferred Stock
(currently, Ms. Beazley), the designation of one member of the board of
directors by the holders of the company's Series B Preferred Stock (currently,
Mr. Sharnak), and the designation of one member of the
                                       52
<PAGE>   57
 
board of directors by the holders of the company's Series C Preferred Stock
(currently, Mr. Allred). In addition, the current certificate of incorporation
provides that the company's chief executive officer will serve as one of the
remaining directors (currently, Mr. Street). These provisions of the certificate
of incorporation will terminate upon the closing of this offering. Thereafter,
the current directors will continue to serve as directors but will be elected by
plurality vote of all stockholders voting together as one class.
 
BOARD COMMITTEES
 
     Our audit committee consists of Mr. Allred, Ms. Griffith Gryga and Mr.

regarding the selection of independent auditors, reviews the results and scope
of the audit and other services provided by our independent auditors, and
evaluates our internal accounting procedures.
 
     Our compensation committee consists of Ms. Beazley, Ms. Griffith Gryga and
Mr. Sharnak. The compensation committee reviews and approves compensation and
benefits for our executive officers. The compensation committee also administers
our compensation and stock plans and makes recommendations to the board of
directors regarding such matters.
 
DIRECTOR COMPENSATION
 
     Other than reimbursing directors for customary and reasonable expenses of
attending board of directors and committee meetings, we do not currently

EMPLOYMENT AGREEMENTS
 
     To reduce our liability and personnel administrative costs, we have entered
into an agreement with The Personnel Department. Under this agreement, The
Personnel Department hires all of our employees and then leases our employees
back to us. The Personnel Department withholds and deposits applicable federal,
state and local income and employment taxes from the wages of our employees, and
provides workers compensation and employment coverage. The Personnel Department

401(K) PLAN
 
     Our employees are eligible to participate in The Personnel Department
401(k) Retirement Plan (the "401(k) Plan"). Pursuant to the 401(k) Plan,
employees may elect to reduce their current compensation by up to the lesser of
24% of eligible compensation or the statutorily prescribed annual limit ($10,000
in 1998). Employees may contribute this amount to the 401(k) Plan. The trustee
under the 401(k) Plan, at the direction of each participant, invests the assets
of the 401(k) Plan in up to 10 different investment funds. The 401(k) Plan is
intended to qualify under Section 401 of the Internal Revenue Code of 1986, as
amended (the "Code") so that contributions by employees to the 401(k) Plan, and
income earned on plan contributions, are not taxable to employees until
withdrawn, and so that the contributions by employees will be deductible by The
Personnel Department, Inc. when made. The Personnel Department, Inc. will make
matching contributions to the 401(k) Plan in an amount equal to 50% of the first
2% of an employee's pretax contributions. An employee becomes eligible for the
matching contribution only if he or she makes a pretax contribution.
Additionally, The Personnel Department may make annual discretionary profit
sharing contributions in amounts to be determined annually by the board of
directors of The Personnel Department. We reimburse The Personnel Department for
any matching or profit sharing contributions on behalf of our employees.
 
STOCK PLANS
 
  1997 STOCK OPTION PLAN
 
     Our 1997 Stock Option Plan (the "Option Plan") was adopted and approved by
our board of directors and stockholders on March 12, 1997. The Option Plan was
amended on October 9, 1997 and on June 15, 1998. The board of directors
terminated the Option Plan on March 19, 1999, and we will make no further
options grants under the Option Plan. Options currently outstanding under the
Option Plan will continue in full force and effect under the terms of the Option
Plan until such outstanding options are exercised or terminated in accordance
with their terms.
 
     As of March 19, 1999, we granted options under the Option Plan to purchase
an aggregate of approximately 983,150 shares of common stock, of which options
to purchase approximately 17,400 shares had been exercised, options to purchase
approximately 164,400 shares had been cancelled (due to expiration or otherwise)
and options to purchase approximately 801,350 shares at a weighted average
exercise price of approximately $3.55 per share remained outstanding. We will
make no future grants under the Option Plan.
 
     The Option Plan provides for the grant of incentive stock options under the
Code to employees and nonstatutory stock options to employees, directors and
consultants. The Option Plan is administered by the
 
                                       55
<PAGE>   60
 
board or a committee appointed by the board which determines recipients and
types of awards to be granted, including the exercise price, number of shares
subject to the award and the exercisability thereof.
 
     The terms of stock options granted under the Option Plan generally may not
exceed 10 years. The board determines the exercise price of options granted
under the Option Plan, provided that the exercise price of an incentive stock
option cannot be less than 100% of the fair market value of the common stock on
the date of the option grant and the exercise price of a nonstatutory stock
option cannot be less than 50% of the fair market value of the common stock on
the date of the option grant. Options granted under the Option Plan vest at the
rate specified in the applicable option agreement. Notwithstanding any other
provisions of the Option Plan to the contrary, options granted under the Option
Plan will be fully vested in the event of the optionee's death or total and
permanent disability. An optionee may not transfer an incentive stock option
other than by will or the laws of descent or distribution and a nonstatutory
stock option is only be transferable to the spouse, children and lineal
descendents of the optionee or to an organization exempt from taxation pursuant
to Section 501(c)(3) of the Code or to which tax deductible contributions may be
made under Section 170 of the Code, or upon such terms as stated in an option
agreement as the board in its discretion determines; provided that, an optionee
whose relationship with us or any related corporation ceases for any reason
(other than by death or permanent and total disability) may exercise vested
options in the three-month period following such cessation (unless such options
terminate or expire sooner by their terms) or in such longer or shorter period
specified in the option agreement. Vested options may be exercised for up to 12
months after an optionee's relationship with us or related corporations ceases
due to death or disability (unless such options terminate or expire sooner by
their terms).
 
     No incentive stock option may be granted to any person who, at the time of
the grant, owns (or is deemed to own) stock possessing more than 10% of the
total combined voting power of us or any affiliate, unless the option exercise
price is at least 110% of the fair market value of the stock subject to the
option on the date of grant, and the term of the option does not exceed five
years from the date of grant. The aggregate fair market value, determined at the
time of grant, of the shares of common stock with respect to which incentive
stock options are exercisable for the first time by an optionee during any
calendar year (under all such plans of us and our affiliates) may not exceed
$100,000. Options may be immediately exercisable (whether such options are
vested or not) at the discretion of the board and if specified in the option
agreement, subject to our right to repurchase any unvested shares.
 
     The options may provide that, prior to our first registration of an equity
security under Section 12 of the Exchange Act of 1934, as amended (the "Exchange
Act"), we may repurchase all or any part of the vested shares exercised, or may
exercise a right of first refusal on any proposed transfer of shares exercised.
 
     Upon certain changes in control, each outstanding option will be assumed or
an equivalent option substituted by the successor corporation or, if the
successor corporation refuses to assume or substitute for outstanding options,
such options will become fully vested and exercisable prior to such change in
control or thereafter terminate.
 
  1999 EQUITY INCENTIVE PLAN
 
     In March 1999, the board adopted and the stockholders approved the 1999
Equity Incentive Plan (the "Incentive Plan"), which replaces the Option Plan
effective as of March 19, 1999. There is currently an aggregate of 425,763
shares of common stock authorized for issuance under the Incentive Plan.
 
     The Incentive Plan provides for the grant of incentive stock options, as
defined under the Code, to employees (including officers and employee-directors)
and nonstatutory stock options, restricted stock purchase awards, stock bonuses
and stock appreciation rights to our and our affiliates' employees (including
officers and employee-directors), directors and consultants. The Incentive Plan
is administered by the board (or a committee appointed by the board) which
determines recipients and types of awards to be granted, including the exercise
price, number of shares subject to the award and the exercisability thereof.
 
                                       56
<PAGE>   61
 
     The terms of options granted under the Incentive Plan may not exceed 10
years. The board (or committee) determines the exercise price of options granted
under the Incentive Plan. However, the exercise price for an incentive stock
option cannot be less than 100% of the fair market value of the common stock on
the date of the option grant, and the exercise price for a nonstatutory stock
option cannot be less than 85% of the fair market value of the common stock on
the date of the option grant. Options granted under the Incentive Plan vest at
the rate specified in the option agreement. Generally, the optionee may not
transfer a stock option other than by will or the laws of descent or
distribution unless the optionee holds a nonstatutory stock option that provides
for transfer in the stock option agreement. However, an optionee may designate a
beneficiary who may exercise the option following the optionee's death. An
optionee whose service relationship with us or any affiliate ceases for any
reason may exercise vested options for the term provided in the option
agreement.
 
     No incentive stock option (and prior to our stock being publicly traded, no
nonstatutory stock option) may be granted to any person who, at the time of the
grant, owns (or is deemed to own) stock possessing more than 10% of the total
combined voting power of us or any affiliate, unless the option exercise price
is at least 110% of the fair market value of the stock subject to the option on
the date of grant and the term of the option does not exceed five years from the
date of grant. In addition, the aggregate fair market value, determined at the
time of grant, of the shares of common stock with respect to which incentive
stock options are exercisable for the first time by an optionee during any
calendar year (under the Incentive Plan and all other stock plans of us and our
affiliates) may not exceed $100,000.
 
     When we become subject to Section 162(m) of the Code (which denies a
deduction to publicly held corporations for certain compensation paid to
specified employees in a taxable year to the extent that the compensation
exceeds $1,000,000), no person may be granted options under the Incentive Plan
covering more than 100,000 shares of common stock in any calendar year.
 
     Shares subject to stock awards that have expired or otherwise terminated
without having been exercised in full again become available for the grant of
awards under the Incentive Plan. Under its general authority to grant and to
amend options, the board (or committee) has the implicit authority to reprice
outstanding options or to offer optionees the opportunity to replace outstanding
options with new options for the same or a different number of shares. Both the
original and new options will count toward the Code Section 162(m) limitation
set forth above.
 
     Restricted stock purchase awards granted under the Incentive Plan may be
granted subject to a repurchase option in our favor in accordance with a vesting
schedule determined by the board (or committee). The price of a restricted stock
purchase award under the Incentive Plan can not be less than 85% of the fair
market value of the stock subject to the award on the date of grant. Stock
bonuses may be awarded in consideration of past services without a purchase
payment. Unless otherwise specified, rights under a stock bonus or restricted
stock bonus agreement generally may not be transferred other than by will or the
laws of descent and distribution during such period as the stock awarded
pursuant to such an agreement remains subject to the agreement.
 
     If there is any sale of substantially all of our assets, any merger,
reverse merger or any consolidation in which we are not the surviving
corporation, or any acquisition by certain persons, entities or groups of 50% or
more of our stock, all outstanding awards under the Incentive Plan either will
be assumed or substituted for by any surviving entity. If the surviving entity
determines not to assume or substitute for such awards, the vesting provisions
of such stock awards will be accelerated and the awards terminated if not
exercised prior to such transaction. In addition, if after the initial public
offering of our common stock, certain specified changes in control of more than
50% of the board occur, then the vesting provisions of all stock awards will be
accelerated.
 
     As of             , 1999,           shares of common stock had been issued
upon the exercise of options granted under the Incentive Plan, options to
purchase           shares of common stock were outstanding and           shares
remained available for future grant. The Incentive Plan will terminate on March
18, 2009 unless sooner terminated by the board (or committee). As of
            , 1999, no stock bonuses or restricted stock have been granted under
the Incentive Plan.

  1999 EMPLOYEE STOCK PURCHASE PLAN
 
     In April 1999 the board adopted the 1999 Employee Stock Purchase Plan (the
"Purchase Plan") covering an aggregate of           shares of common stock. The
Purchase Plan will become effective on the effective date of our initial public
offering. The Purchase Plan is intended to qualify as an "employee stock
purchase plan" within the meaning of Section 423 of the Code. Under the Purchase
Plan, the board may authorize participation by eligible employees, including
officers, in periodic offerings following the adoption of the Purchase Plan. The
offering period for any offering will be no longer than 27 months.
 
     The Purchase Plan provides a means by which our and our designated
affiliates' employees may purchase our common stock through payroll deductions.
The Purchase Plan is implemented by offerings of rights to eligible employees.
Under the Plan, we may specify offerings with a duration of not more than 27
months, and may specify shorter purchase periods within each offering. The first
offering will begin on the effective date of our initial public offering and
will end on June 30, 2000. Purchases will occur on December 31, 1999 and June
30, 2000. Unless otherwise determined by the board, common stock is purchased
for accounts of employees participating in the Purchase Plan at a price per
share equal to the lower of (i) 85% of the fair market value of a share of
common stock on the date of commencement of participation in the offering or
(ii) 85% of the fair market value of a share of common stock on the date of
purchase. Generally, all regular employees, including executive officers, who
work at least 20 hours per week and who are customarily employed by us or an
affiliate for at least five months per calendar year may participate in the
Purchase Plan and may authorize payroll deductions of up to 15% of their base
compensation for the purchase of stock under the Purchase Plan.
 
     Eligible employees may be granted rights only if the rights together with
any other rights granted under employee stock purchase plans do not permit such
employee's rights to purchase our stock to accrue at a rate which exceeds
$25,000 of fair market value of such stock for each calendar year in which such
rights are outstanding. No employee is eligible for the grant of any rights
under the Purchase Plan if immediately after such rights are granted, such
employee has voting power over 5% or more of our outstanding capital stock.
 
     As of             , 1999, no shares of common stock had been purchased
under the Purchase Plan.
 
     In the event of certain changes of control, the board has discretion to
provide that each right to purchase common stock will be assumed or an
equivalent right substituted by the successor corporation, or the board may
shorten the offering period and provide for all sums collected by payroll
deductions to be applied to purchase stock immediately prior to the change in
control. The Purchase Plan will terminate at the board's direction or when all
of the shares reserved for issuance have been purchased.

                             PRINCIPAL STOCKHOLDERS
 
     The following table sets forth information with respect to beneficial
ownership of our common stock as of February 28, 1999 for:
 
     - Each person (or group of affiliated persons) known to us to own
       beneficially more than 5% of the common stock,
 
     - Each of our directors and Named Executive Officers, and
 
     - All of our directors and executive officers as a group.
 
     The information has been adjusted to reflect the sale of the common stock
in this offering (assuming no exercise of the underwriters' over-allotment
option) and the conversion of all outstanding shares of preferred stock into
common stock.
 
     In accordance with the rules of the Securities and Exchange Commission, the
following table gives effect to the shares of common stock that could be issued
upon the exercise of outstanding options within 60 days of February 28, 1999.
Unless otherwise noted in the footnotes to the table and subject to community
property laws where applicable, the following individuals have sole voting and
investment control with respect to the shares beneficially owned by them.

                              CERTAIN TRANSACTIONS
 
TRANSACTIONS WITH TELECONCEPTS
 
     During 1996 and 1997, we purchased certain administrative and operating
services from TeleConcepts. The aggregate amount of services purchased by us
from TeleConcepts during 1996 and 1997 was approximately $1.2 million and
approximately $113,000, respectively. During 1996, TeleConcepts (whose sole
shareholders were Ms. Beazley, Mr. Street and Mr. Frank) periodically made
advances to fund our operations. TeleConcepts distributed such receivables to
Ms. Beazley, Mr. Street and Mr. Frank, who converted them into shares of common
stock. Please see our discussion in "-- Common Stock Financing of Colorado
Predecessor" below.
 
COMMON STOCK FINANCING OF COLORADO PREDECESSOR
 
     From March 1, 1996 through December 30, 1996, prior to our reincorporation
in Delaware, our Colorado predecessor corporation sold an aggregate of 857,350
shares of its common stock to certain existing stockholders at a purchase price
of $4.76 per share. 850,000 of the shares (which, in connection with the
reincorporation, were converted into an aggregate of 424,996 shares of our
common stock and 850,000 shares of our Series A Preferred Stock) were sold to
the following directors, executive officers and principal stockholders for an

     All of these shares were issued upon the conversion of the advances
discussed above in "--Transactions with TeleConcepts."
 
TRANSACTIONS WITH INTERNET EXPRESS, LLC
 
     On March 1, 1997, we sold to Internet Express, LLC ("IEX") certain assets
related to our Internet access business in exchange for $925,000 and the
assumption of related liabilities. The price was based, in part, on the purchase
price for these assets negotiated with an independent third-party (which
transaction was not consummated). The board of directors subsequently increased
the purchase price to reflect the current market value of the assets. This
transaction was approved by the independent director and our stockholders. We
also entered into a Co-Location Agreement with IEX pursuant to which IEX leases
space at our offices on a month-to-month basis at the rate of $500 per month. In
addition, we purchased Internet access and subleased office space from IEX
during 1997 and 1998. The aggregate amount of the payments made to IEX during
1997 and 1998 was $44,900 and $22,789, respectively. Mr. Street and Ms. Beazley
each own approximately 20% of the membership interests in IEX.
 
SERIES B FINANCING
 
     On April 8, 1997, we issued 527,579 shares of Series B Preferred Stock to
American Express, a principal stockholder, at a purchase price of $5.69 per
share. We also granted to American Express a one-year option to purchase up to
527,579 additional shares of Series B Preferred Stock. On March 23, 1998,
American Express exercised a portion of such option and acquired an additional
356,073 shares of Series B Preferred Stock at $5.69 per share. The unexercised
portion of the option terminated. In connection with its investment, American
Express received the right, subject to certain restrictions, to designate a
member of our board of directors. Mr. Sharnak currently serves as that designee.
 
     In connection with its initial investment, American Express also entered
into a Co-Marketing Program Agreement with us pursuant to which we provide
Web-based email services to American Express
 
                                       61

Cardmembers and other consumers. Please refer to our discussion in
"Business -- Strategic Relationships" for our discussion of this agreement.
 
     In connection with the initial American Express investment, we entered into
Stock Restriction Agreements with each of Mr. Street, Ms. Beazley and Mr. Frank.
The agreements granted to us an option to repurchase shares of common stock and
Series A Preferred Stock held by Mr. Street, Ms. Beazley and Mr. Frank, at a
price of $.57 per share of common stock and a price of $4.76 per share of Series
A Preferred Stock, in the event that Mr. Street is terminated for cause or
voluntarily ceases to be an employee, director or consultant prior to October 8,
1998 (in the case of the agreements with Ms. Beazley and Mr. Frank) or April 8,
2000 (in the case of the agreement with Mr. Street).
 
SERIES C FINANCING
 
     On October 17, 1997, we issued an aggregate of 736,376 shares of Series C
Preferred Stock to Premiere Technologies, a principal stockholder, and certain
other investors at a purchase price of $6.79 per share. We also granted options
exercisable on or prior to May 1, 1998 to purchase up to 736,376 additional
shares of Series C Preferred Stock. On March 23, 1998, such options were
exercised in full, at which time we also issued an additional 486,918 shares of
Series C Preferred Stock, all at $6.79 per share. On May 13, 1998, we issued an
additional 74,000 shares of Series C Preferred Stock at $6.79 per share. Of the
2,033,670 shares of Series C Preferred Stock sold by us, an aggregate of
1,958,170 shares were sold to the following directors, officers and principal
stockholders for an aggregate purchase price of $13,295,974:

GUARANTEE OF BANK LOAN
 
     Mr. Street is the co-signer of our Business Loan Agreement with State Bank
and Trust of Colorado Springs. As of March 31, 1999, the outstanding principal
amount under such agreement was approximately $1.7 million. In consideration for
his personal guarantee of the loan, during 1997 we granted to Mr. Street options
to purchase an aggregate of 65,000 shares of common stock under the Option Plan
at a weighted average exercise price of $.60 per share.
 
     We believe that each of the transactions described above was carried out on
terms that were no less favorable to us than those that would have been obtained
from unaffiliated third parties. Any future transactions between us and any of
our directors, officers or principal stockholders will be on terms no less
favorable to us than could be obtained from unaffiliated third parties and will
be approved by a majority of the independent and disinterested members of the
board of directors.

                           DESCRIPTION OF SECURITIES
 
     The following description of our securities reflects changes that will be
made to our certificate of incorporation and bylaws upon the closing of this
offering. We have filed our restated certificate of incorporation and amended
and restated bylaws as exhibits to the registration statement of which this
prospectus is a part.
 
     Our authorized capital stock consists of           shares of common stock,
par value $.001 per share, and           shares of preferred stock, par value
$.001 per share.
 
COMMON STOCK
 
     As of the date of this prospectus, there are 6,085,581 shares of common
stock outstanding and held of record by 162 stockholders. Upon the closing of
this offering, there will be           shares of common stock outstanding
(assuming no exercise of the underwriters' over-allotment option).
 
     Holders of common stock are entitled to one vote for each share on all
matters submitted to a vote of stockholders. Holders of common stock are not
entitled to cumulative voting rights in the election of directors. Accordingly,
minority stockholders will not be able to elect directors on the basis of their
votes alone. Subject to preferences that may be applicable to any
then-outstanding shares of preferred stock, holders of common stock are entitled
to receive ratably such dividends as may be declared by our board of directors.
In the event we liquidate, dissolve or wind up our affairs, holders of common
stock are entitled to share ratably in all assets remaining after payment of
liabilities and the liquidation preferences of any then-outstanding shares of
preferred stock. Holders of common stock have no preemptive, subscription,
redemption or conversion rights.
 
PREFERRED STOCK
 
     Our board of directors is authorized, without further stockholder approval,
to issue up to an aggregate of           shares of preferred stock in one or
more series. The board of directors may fix or alter the designations,
preferences, rights and any qualifications, limitations or restrictions of the
shares of each such series, and the dividend rights, dividend rates, conversion
rights, voting rights, terms of redemption, redemption price or prices and
liquidation preferences. The issuance of preferred stock could:
 
     - Adversely affect the voting power of holders of common stock;
 
     - Adversely affect the likelihood that the holders of common stock will
       receive dividend payments and payments upon liquidation; and
 
     - Delay, defer or prevent a change in control.
 
We have no present plans to issue any shares of preferred stock.
 
WARRANT
 
     As of the date of this prospectus, we have one outstanding warrant to
purchase 45,994 shares of common stock at an exercise price of $14.75 per share.
We issued the warrant to an investment banking firm in connection with its
services as placement agent for our August 1998 private placement of shares of
Series D Preferred Stock. The warrant expires on August 12, 2003. The warrant
contains anti-dilution provisions providing for adjustments of the exercise
price and the number of shares of common stock underlying the warrant upon the
occurrence of any recapitalization, reclassification, stock dividend, stock
split, stock combination or similar transaction. The shares of common stock
issuable upon exercise of the warrant carry registration rights, as discussed
below.
 
REGISTRATION RIGHTS
 
     Pursuant to the Second Amended and Restated Investor Rights Agreement,
holders of 6,098,975 shares of common stock, including the common stock issuable
under the warrant described in
 
                                       64
<PAGE>   69
 
the preceding paragraph, have certain rights to require us to register their
shares for resale under the Securities Act of 1933, as amended (the "Securities
Act"), during the five-year period following this offering.
 
     With certain limitations, the holders of more than 50% of such shares may
demand that we register shares having an aggregate offering price to the public
of more than $10,000,000. We are not required to effect more than two demand
registrations, provided at least 70% of the shares requested to be included in
the demand registrations are, in fact, included therein. In addition, these
stockholders are entitled to piggyback registration rights with respect to any
public offering registration statement we file under the Securities Act
following this offering, with certain limitations. Further, at any time after we
become eligible to file a registration statement on Form S-3 or any similar
short-form registration statement, such stockholders may require us to file such
registration statements from time to time, again with certain limitations. We
are generally required to bear all of the expenses of these registrations,
except underwriting discounts and commissions. Registration of any of the shares
of common stock entitled to these registration rights would result in such
shares becoming freely tradable without restriction under the Securities Act.
 
     Upon completion of this offering, the registration rights with respect to
the shares held by a stockholder will terminate if the stockholder holds less
than 1% of the then-outstanding shares of common stock and the stockholder's
shares are entitled to be resold in a 90-day period under Rule 144 promulgated
under the Securities Act.
 
ANTI-TAKEOVER EFFECTS OF CERTAIN PROVISIONS OF DELAWARE LAW AND OUR CERTIFICATE
OF INCORPORATION
AND BYLAWS
 
     We are subject to the provisions of Section 203 of the Delaware General
Corporation Law, which generally prohibits a publicly-held Delaware corporation
from engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder, unless the interested stockholder attained
that status with the approval of the corporation's board of directors or unless
the business combination is approved in a prescribed manner. "Business
combinations" include mergers, asset sales and other transactions resulting in a
financial benefit to the interested stockholder. With certain exceptions, an
"interested stockholder" is a person who, together with affiliates and
associates, owns, or within three years did own, fifteen percent (15%) or more
of a corporation's voting stock. This statute could prohibit or delay the
accomplishment of mergers or other takeover or change-in-control attempts and,
accordingly, may discourage attempts to acquire us.
 
     The following provisions of our restated certificate of incorporation and
amended and restated bylaws that will become effective upon the closing of this
offering may have an anti-takeover effect and may delay or prevent a tender
offer or takeover attempt that a stockholder might consider to be in its best
interest, including attempts that might result in a premium over the market
price for the common stock:
 
     CLASSIFIED BOARD OF DIRECTORS. Our board of directors will be divided into
three classes. The directors in class I will hold office until the first annual
meeting of stockholders following this offering, the directors in class II will
hold office until the second annual meeting of stockholders following this
offering, and the directors in class III will hold office until the third annual
meeting of stockholders following this offering. After each such election, the
directors in that class will serve for terms of three years. The classification
system of electing directors may tend to discourage a third party from making a
tender offer or otherwise attempting to obtain control of us and may maintain
the incumbency of the board of directors, since such classification generally
increases the difficulty of replacing a majority of the directors.
 
     BOARD OF DIRECTOR VACANCIES. The board of directors will be authorized to
fill vacant directorships and to increase the size of the board of directors.
This may deter a stockholder from removing incumbent directors and
simultaneously gaining control of the board of directors by filling the
resulting vacancies with its own nominees.
 
                                       65
<PAGE>   70
 
     STOCKHOLDER ACTION; SPECIAL MEETINGS OF STOCKHOLDERS. Our stockholders will
not be permitted to take action by written consent, but only at duly called
annual or special meetings of stockholders. In addition, special meetings of
stockholders may be called only by the chairman of the board, the chief
executive officer or a majority of the board of directors.
 
     ADVANCE NOTICE REQUIREMENTS FOR STOCKHOLDER PROPOSALS AND DIRECTOR
NOMINATIONS. Stockholders seeking to bring business before an annual meeting of
stockholders, or to nominate candidates for election as directors at an annual
meeting of stockholders, must deliver a written notice to our principal
executive offices within a prescribed time period. Our amended and restated
bylaws also set forth specific requirements as to the form and content of a
stockholder's notice. These provisions may preclude stockholders from bringing
matters before an annual meeting of stockholders or from making nominations for
the election of directors at an annual meeting of stockholders.
 
     AUTHORIZED BUT UNISSUED SHARES. The authorized but unissued shares of
common stock and preferred stock are available for future issuance without
stockholder approval, subject to limitations imposed by the Nasdaq National
Market. We may use these additional shares for a variety of corporate purposes,
including future public offerings to raise additional capital, acquisitions and
employee benefit plans. The existence of authorized but unissued and unreserved
common stock and preferred stock could render more difficult or discourage an
attempt to obtain control of us by means of a proxy contest, tender offer,
merger or otherwise.
 
LIMITATIONS ON LIABILITY AND INDEMNIFICATION MATTERS
 
     Our amended and restated bylaws that will become effective upon the closing
of this offering provide that we will indemnify our directors and executive
officers to the fullest extent permitted by Delaware law and may indemnify our
other officers, employees and other agents to the fullest extent permitted by
Delaware law.
 
     In addition, our restated certificate of incorporation that will become
effective upon the closing of this offering provides that, to the fullest extent
permitted by Delaware law, our directors will not be personally liable to us or
our stockholders for monetary damages for any breach of fiduciary duty as
directors. This provision of the restated certificate of incorporation does not
eliminate the directors' duty of care. In appropriate circumstances, equitable
remedies such as an injunction or other forms of non-monetary relief are
available under Delaware law. This provision also does not affect the directors'
responsibilities under any other laws, such as the federal securities laws and
state and federal environmental laws.
 
     Each director will continue to be subject to liability for:
 
     - Breach of a director's duty of loyalty to us and our stockholders;
 
     - Acts or omissions not in good faith or that involve intentional
       misconduct or a knowing violation of law;
 
     - Unlawful payments of dividends or unlawful stock repurchases or
       redemptions; and
 
     - Any transaction from which a director derived an improper personal
       benefit.
 
     We also intend to enter into indemnity agreements with our directors and
executive officers. We have purchased liability insurance for our directors and
executive officers.
 
     There is no pending litigation or proceeding involving any of our directors
or officers as to which indemnification is being sought. We are not aware of any
pending or threatened litigation that may result in a claim for indemnification.
 
LISTING
 
     We have applied for listing of the common stock on the Nasdaq National
Market under the trading symbol MBOX.
 
TRANSFER AGENT AND REGISTRAR
 
     We have appointed Norwest Bank Minnesota, National Association, to serve as
the transfer agent and registrar for the common stock.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Prior to this offering, there has been no public market for our common
stock. We cannot predict what effect, if any, market sales of shares or the
availability of shares for sale will have on the market price of our common
stock prevailing from time to time. Nevertheless, sales of substantial amounts
of common stock in the public market, or the perception that such sales could
occur, could adversely affect the market price of the common stock and could
impair our future ability to raise capital through the sale of our equity
securities.
 
     Upon the closing of this offering, we will have a total of           shares
of common stock outstanding, assuming no exercise of the underwriters'
over-allotment option and no exercise of options or warrants. Of the outstanding
shares, the           shares being sold in this offering will be freely
tradable, except that any shares held by our "affiliates" may only be sold in
compliance with the limitations described below. The remaining 6,085,581 shares
of common stock will be "restricted securities" that may be sold in the public
market only if they are registered under the Securities Act or if they qualify
for an exemption from registration under Rule 144, 144(k) or 701 promulgated
under the Securities Act.
 
     Subject to the lock-up agreements described below and the provisions of
Rules 144, 144(k) and 701, additional shares will become available for sale in
the public market as follows:

                                                                  =========
</TABLE>
 
     The underwriting agreement provides that the obligations of the
underwriters are subject to approval of certain legal matters by counsel and to
various other conditions. The nature of the underwriters' obligations is that
they are committed to purchase and pay for all of the above shares of common
stock if any are purchased.
 
     The underwriters propose to offer the shares of common stock directly to
the public at the "initial public offering price" set forth on the cover page of
this prospectus and at that price less a concession not in excess of $     per
share of common stock to certain other dealers who are members of the National
Association of Securities Dealers, Inc. The underwriters may allow, and those
dealers may reallow, concessions not in excess of $     per share of common
stock to certain other dealers. After this offering, the offering price,
concessions and other selling terms may be changed by the underwriters.
 
     We have granted a 30-day over-allotment option to the underwriters to
purchase up to an aggregate of           additional shares of common stock at
the "initial public offering price" less the "underwriting discounts," each as
set forth on the cover page of this prospectus. If the underwriters exercise
this option in whole or in part, then each of the underwriters will be severally
committed, subject to certain conditions, including the approval of certain
matters by counsel, to purchase the additional shares of common stock in
proportion to their respective purchase commitments as indicated in the
preceding table.
 
     The underwriters, at our request, have reserved for sale at the initial
public offering price up to      percent (     %) of the shares of common stock
to be sold in this offering for sale to our employees and directors and to other
persons designated by us. Any purchase of these reserved shares will reduce the
number of shares available for sale to the general public. The underwriters will
offer any reserved shares not so purchased on the same basis as the other shares
offered hereby.
 
     The underwriters do not intend to confirm sales of common stock to any
accounts over which they exercise discretionary authority.
 
     The underwriting agreement provides that we will indemnify the underwriters
against certain liabilities under the Securities Act or will contribute to
payments that the underwriters may be required to make in respect thereof.
 
     Directors, officers and stockholders who hold in the aggregate
shares of common stock have agreed that they will not sell any shares of common
stock without the prior written consent of Bear, Stearns & Co. Inc for a period
of 180 days from the date of this prospectus. However, Bear, Stearns & Co. Inc.
may, in its sole discretion and at any time or from time to time, without notice
to our stockholders or Nasdaq, release all or any portion of the shares subject
to lock-up agreements.
 
     We have agreed that for a period of 180 days after the date of this
prospectus we will not, without the prior written consent of Bear, Stearns & Co.
Inc., sell or otherwise dispose of any shares of common stock, except for the
shares of common stock offered by this prospectus, the shares of common stock
issuable upon exercise of outstanding options and warrants, and the grant of
additional options and purchase rights
 
                                       68
<PAGE>   73
 
under our stock plans and the issuance of common stock pursuant thereto,
provided the holders of such shares, options or rights agree to the 180 day
lock-up agreement.
 
     Prior to this offering, there has been no public market for our common
stock. Accordingly, negotiations between us and the representatives of the
underwriters will determine the initial public offering price for the common
stock. Among the factors to be considered in those negotiations will be:
 
     - Our recent results of operations;
 
     - Estimates of our prospects as well as the industry in which we compete;
 
     - An assessment of our management;
 
     - The general state of the securities markets at the time of this offering;
       and
 
     - The prices of similar securities of generally comparable companies.
 
     We have applied for listing of the common stock on the Nasdaq National
Market under the trading symbol MBOX. We cannot assure you that an active or
orderly trading market will develop or that the common stock will trade in the
public markets subsequent to this offering at or above the initial public
offering price.
 
     The following table shows the underwriting discounts and commissions to be
paid by us to the underwriters in connection with this offering. These amounts
are shown assuming both no exercise and full exercise of the underwriters'
option to purchase additional shares of common stock.

     In order to facilitate this offering, persons participating in the offering
may engage in transactions that stabilize, maintain or otherwise affect the
price of the common stock during and after the offering, including
over-allotment, stabilizing and short-covering transactions and the impositions
of penalty bids. Persons participating in this offering also may engage in
passive market-making transactions in the common stock on the Nasdaq National
Market. Specifically, the underwriters may over-allot or otherwise create a
short position in the common stock for their own account by selling more shares
of common stock than have been sold to them by us. The underwriters may elect to
cover this short position by purchasing shares of common stock in the open
market or by exercising the over-allotment option granted to the underwriters.
In addition, the underwriters may stabilize or maintain the price of the common
stock by bidding for or purchasing shares of common stock in the open market and
may impose penalty bids, under which selling concessions allowed to syndicate
members or other broker-dealers participating in this offering are reclaimed if
shares of common stock previously distributed in the offering are repurchased in
connection with stabilization transactions or otherwise. The effect of these
transactions may be to stabilize or maintain the market price at a level above
that which might otherwise prevail in the open market. The imposition of a
penalty bid also may affect the price of the common stock to the extent that it
discourages resales. No representation is made as to the magnitude or effect of
this stabilization or other transactions. These transactions may be effected on
the Nasdaq National Market or otherwise and, if commenced, may be discontinued
at any time.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To USA.NET, Inc.:
 
     We have audited the accompanying balance sheets of USA.NET, Inc. (a
Delaware corporation) as of December 31, 1997 and 1998, and the related
statements of operations, stockholders' equity and cash flows for each of the
three years in the period ended December 31, 1998. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of USA.NET, Inc., as of
December 31, 1997 and 1998, and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 1998 in conformity
with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
(1) ORGANIZATION AND NATURE OF BUSINESS
 
     USA.NET, Inc., a Delaware corporation ("USA.NET-Delaware" or, with its
predecessor entity, the "Company") is a leading provider of email and advanced
messaging solutions on the Internet for consumers, Web portals and businesses.
The Company's consumer email service, NET@DDRESS, is offered free of charge and
provides users with a permanent, portable and private email address accessible
from any computer connected to the Internet. During 1998, the Company introduced
its messaging services for Web portals and its specialized and comprehensive
outsourced solutions for businesses.
 
     USA.NET, Inc., a Colorado corporation ("USA.NET-Colorado") was formed as a
S corporation in 1991, as Community News Service Inc., an information services
company providing Internet access and other Internet-related services to
consumer and commercial customers throughout the United States. In 1995, the
Company began the development of its email solutions. Effective March 1, 1997,
the Company sold the Internet service provider ("ISP") business segment (Notes 3
and 9).
 
     On March 12, 1997, a reincorporation of USA.NET-Colorado as a Delaware
corporation was effected by a merger (the "Reincorporation Merger") of
USA.NET-Colorado with and into USA.NET-Delaware, and each share of
USA.NET-Colorado common stock was exchanged for one-half share of USA.NET-
Delaware common stock and one share of USA.NET-Delaware Series A convertible
preferred stock ("Series A"). USA.NET-Delaware was the surviving corporation.
Also as a result of the Reincorporation Merger, the Company increased the total
number of authorized common and preferred shares and established a par value of
$.001 per share for both common and preferred stock.
 
     The Company is subject to various risks and uncertainties frequently
encountered by companies in the early stages of development, particularly
companies in the new and rapidly evolving market for Internet-based products and
services. Such risks and uncertainties include, but are not limited to, its
limited operating history, an evolving and unpredictable business model and the
management of rapid growth. To address these risks, the Company must, among
other things, maintain and increase its customer base, implement and
successfully execute its business and marketing strategy, continue to develop
and upgrade its technology, provide superior customer service and attract,
retain and motivate qualified personnel. There can be no guarantee that the
Company will be successful in addressing such risks. To date, substantially all
of the Company's revenue has been derived from the sale of advertising on its
Web sites. The Internet as an advertising medium has not been available for a
sufficient period of time to gauge its effectiveness as compared to traditional
advertising outlets.
 
     The Company has not yet achieved profitability and expects to incur net
losses for the foreseeable future. The Company incurred net losses from
continuing operations of $2,075,072 in 1996, $5,673,912 in 1997 and $19,227,787
in 1998. As of December 31, 1998, the Company's accumulated deficit was
$28,571,068. The Company expects to continue to lose money for the foreseeable
future. The Company has not generated sufficient revenue to cover the
substantial amounts spent to create, launch and enhance its services. If the
Company's revenue does not increase substantially, the Company may never become
profitable. Even if the Company does achieve profitability in the future, it may
not sustain or increase its profitability. The Company has historically funded
its operations by selling stock and obtaining loans from banks. The Company
expects that its growth may require significant external financing within the
next year. Management believes that the Company has capital available to it from
third parties, and if such capital is not forthcoming, a stockholder has
committed to fund the Company's operations through at least December 31, 1999,
if necessary.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS
 
     The presentation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions. These estimates and assumptions may affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
  CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS
 
     The Company considers investments in highly liquid instruments purchased
with an original maturity of 90 days or less to be cash equivalents.
 
     All of the Company's short-term investments, consisting principally of
commercial paper and medium term notes, are classified as available for sale.
Unrealized holding gains and losses, if material, are included as a separate
component of other comprehensive income. At December 31, 1997 and 1998,
unrealized holding gains and losses are not material. Realized gains and losses
are recorded in the statement of operations upon selling the security.
 
  ACCOUNTS RECEIVABLE
 
     The Company maintains an allowance for doubtful accounts based upon the
expected collectibility of accounts receivable. At December 31, 1997 and 1998,
the allowance for doubtful accounts was approximately $29,000 and $151,000,
respectively.
 
  CONCENTRATION OF CREDIT RISK
 
     Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist primarily of cash and cash equivalents,
short-term investments and accounts receivable. The Company has no significant
off-balance sheet concentrations of credit risk, such as foreign exchange
contracts, option contracts or other foreign currency hedging arrangements. The
Company maintains its cash balances in the form of bank demand deposits and
money market accounts with financial institutions that management believes are
creditworthy. The Company maintains its short-term investments in certificates
of deposit, and high quality commercial paper and corporate debt securities.
Accounts receivable are typically unsecured and are derived from transactions
with and from advertisers primarily located in the United States. The Company
performs ongoing credit evaluations of its customers and maintains reserves for
potential credit losses.
 
     As discussed in Note 7, the Company has three and one customers that
accounted for more than 10% of 1997 and 1998 revenue, respectively, and four and
two customers that accounted for more than 10% of accounts receivable at
December 31, 1997 and 1998, respectively. The loss of significant advertisers
and/or distribution channels to the Company's users could result in a
significant reduction of revenues.
 
  PROPERTY AND EQUIPMENT
 
     Property and equipment are stated at cost and depreciation is provided
using the straight-line method, generally over estimated useful lives of five
years. Maintenance and repairs are expensed as incurred and major additions,
replacements and improvements are capitalized.
 
     Leasehold improvements are amortized using the straight-line method over
the shorter of the useful life of five years or the life of the lease.

                                                      ==========   ===========
</TABLE>
 
  IMPAIRMENT OF LONG-LIVED ASSETS
 
     The Company reviews its long-lived assets for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. The Company evaluates the recoverability of its long-lived
assets based on estimated undiscounted future cash flows and provides for
impairment if such undiscounted cash flows are insufficient to recover the
carrying amount of the long-lived asset.
 
  FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The Company's financial instruments consist of cash equivalents, short-term
investments, short-term trade receivables and payables, and a note payable. The
carrying values of the cash equivalents, short-term investments and short-term
trade receivables and payables approximate their fair values. Based on borrowing
rates currently used by the Company for financing, the carrying value of the
note payable approximates its estimated fair value.
 
  REVENUE RECOGNITION
 
     The Company currently generates substantially all of its revenue from the
sale of advertising via its Web-based email services. Advertising revenue
consists of sponsorships, banner advertising, the placement of buttons, and the
use of a logout page, all of which provide users with direct links to the
advertiser's Web site, and from advertising for direct delivery content
providers. Advertising revenue is derived from both short-term and long-term
advertising contracts in which the Company delivers impressions (a single
display of an advertisement to a subscriber) for a fee or is compensated for
generating leads or transactions. Revenue generated by these contracts are
generally recognized ratably as earned, which typically coincides with when the
services are performed, provided that the Company does not have any significant
remaining obligations and collection of the resulting receivable is probable.
Company obligations typically include guarantees of a minimum number of
impressions. To the extent minimum guaranteed impressions are not met, the
Company defers recognition of the corresponding revenue until the remaining
guaranteed impression levels are achieved.
 
     As discussed in Note 5, certain agreements require that a portion of the
revenue recorded under these agreements be shared.
 
  INCOME TAXES
 
     Prior to the Reincorporation Merger, the Company elected to be taxed as an
S corporation under Subchapter S of the Internal Revenue Code, and accordingly,
income or loss attributed to the Company's operations was allocated to its
stockholders to be reported on their personal tax returns. Tax net operating
losses incurred during this period are not available to offset the Company's
future taxable income, if any.
 
                                       F-9
<PAGE>   84
                                 USA.NET, INC.
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     Subsequent to the Reincorporation Merger, the Company elected to be taxed
as a C corporation. The current provision for income taxes represents actual or
estimated amounts payable on tax return filings each year. Deferred tax assets
and liabilities are recorded for the estimated future tax effects of temporary
differences between the tax basis of assets and liabilities and amounts reported
in the accompanying balance sheets, and for operating loss and tax credit
carryforwards. The change in deferred tax assets and liabilities for the period
measures the deferred tax provision or benefit for the period. Effects of
changes in enacted tax laws on deferred tax assets and liabilities are reflected
as adjustments to the tax provision or benefit in the period of enactment. The
Company's deferred tax assets have been completely reduced by a valuation
allowance because management does not believe realization of the deferred tax
assets is sufficiently assured at each balance sheet date (Note 8).
 
  PRODUCT DEVELOPMENT
 
     Costs incurred in the development of new products and enhancements to
existing products and services are charged to expense as incurred.
 
  CHANNEL ACQUISITION COSTS
 
     Channel acquisition costs paid to acquire access to customers are
capitalized if the arrangement contains guarantees of minimum revenue which
support the amount paid.
 
  ADVERTISING COSTS
 
     Advertising costs are expensed as incurred and are included in sales and
marketing expense in the accompanying statements of operations. The Company does
not incur any material direct-response advertising costs. Advertising expense
totaled $251,778, $1,681,738 and $3,988,501 in 1996, 1997 and 1998,
respectively, related to continuing operations.
 
  STOCK-BASED COMPENSATION
 
     The Company accounts for its employee stock option plans and other
stock-based compensation arrangements in accordance with the provisions of
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" ("APB Opinion No. 25"), and related interpretations. The Company
adopted the disclosure-only provisions of SFAS No. 123 "Accounting for
Stock-Based Compensation" ("SFAS No. 123"), which allows entities to continue to
apply the provisions of APB Opinion No. 25 for transactions with employees and
provide pro forma disclosures for employee stock grants made in 1997 and future
years as if the fair-value-based method of accounting in SFAS No. 123 had been
applied to these transactions. The Company accounts for equity instruments
issued to non-employees in accordance with the provisions of SFAS No. 123.
 
  NET LOSS PER SHARE
 
     Net loss per share is calculated in accordance with SFAS No. 128, "Earnings
Per Share" ("SFAS No. 128"), and Securities and Exchange Commission ("SEC")
Staff Accounting Bulletin No. 98 ("SAB 98"). Under the provisions of SFAS No.
128 and SAB 98, basic net loss per share is computed by dividing net loss for
the period by the weighted average number of common shares outstanding for the
period. Diluted net loss per share is computed by dividing the net loss for the
period by the weighted average number of common and potential common shares
outstanding during the period if the effect of the potential common shares is
dilutive. The Company has excluded the weighted average effect (using the
treasury stock method) of common stock issuable upon conversion of all
convertible preferred stock,

warrants and stock options from the computation of diluted earnings per share as
the effect of all such securities is anti-dilutive for all periods presented.
The shares excluded are as follows:

</TABLE>
 
     At December 31, 1998, the Company had issued rights to 6,414,265 shares of
common stock under such agreements.
 
  PRO FORMA NET LOSS PER SHARE (UNAUDITED)
 
     Pro forma net loss per share for the year ended December 31, 1998 is
computed using the weighted average number of common shares outstanding,
including the pro forma effects of the automatic conversion of the Company's
Series A, B, C and D convertible preferred stock into shares of the Company's
common stock as if such conversion occurred on January 1, 1998, or at the date
of original issuance, if later. The resulting pro forma adjustment includes an
increase in the weighted average shares used to compute basic and diluted net
loss per share of approximately 4,200,000 shares for the year ended December 31,
1998. The pro forma effects of these transactions are unaudited.
 
  PRO FORMA STOCKHOLDERS' EQUITY (UNAUDITED)
 
     Effective upon the closing of the Company's planned initial public
offering, all outstanding shares of Series Preferred (as defined below) will
automatically convert into 5,536,871 shares of common stock. The pro forma
effects of these transactions are unaudited and have been reflected in the
accompanying pro forma balance sheet at December 31, 1998.
 
  COMPREHENSIVE INCOME
 
     Effective January 1, 1998, the Company adopted the provisions of SFAS No.
130, "Reporting Comprehensive Income" ("SFAS No. 130"). 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. From its inception through
December 31, 1998, the Company has not had any material transactions that are
required to be reported in comprehensive income as compared to its net loss.
 
  SEGMENT INFORMATION
 
     In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information" ("SFAS No.
131"). 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 has one reportable operating segment
at December 31, 1998.
 
  RECENT ACCOUNTING PRONOUNCEMENTS
 
     In March 1998, the American Institute of Certified Public Accountants
issued Statement of Position ("SOP") No. 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use," which provides
guidance on accounting for the cost of such software. SOP No. 98-1 is effective
for

financial statements for fiscal years beginning after December 15, 1998. The
Company does not expect that the adoption of SOP No. 98-1 will have a material
impact on its financial statements.
 
     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS No. 133"). The Company is required to
adopt SFAS No. 133 in the year ended December 31, 2000. SFAS No. 133 establishes
methods of accounting for derivative financial instruments and hedging
activities related to those instruments as well as other hedging activities. To
date, the Company has not entered into any derivative financial instruments or
hedging activities.
 
  RECLASSIFICATIONS
 
     Certain prior years' balances were reclassified to conform to the current
year presentation.
 
(3) RELATED PARTY TRANSACTIONS
 
     Prior to 1997, the Company substantially relied upon an entity affiliated
through common ownership for management, facilities and other administrative and
operating activities. This entity charged the Company for its calculated share
of the related costs incurred and paid by the affiliated entity. Such costs
totaled $816,948 in 1996, of which $528,282 relates to continuing operations.
Because such costs were shared, the Company's management believes that the costs
incurred on a stand-alone basis would have been greater than amounts allocated
to the Company by the affiliated entity. During 1996, the Company ceased its
dependence on the affiliated entity. During 1997, the affiliated entity was sold
to a third party.
 
     This entity also provided long distance telephone services to the Company.
For the periods prior to its sale, the related telephone services totaled
$373,531 and $113,159 for the years ended December 31, 1996 and 1997,
respectively, of which $3,142 and $54,717, respectively, are reflected in
continuing operations. The Company had no payables to this affiliated entity for
telephone services at December 31, 1997.
 
     During 1996, this entity periodically made advances to fund the Company's
operations. This entity distributed such receivables to certain mutual
stockholders, who converted them into shares of the Company's common stock.
 
     During March 1997, the Company entered into a lease agreement for office
space with a related party. The total rent expense related to this lease for the
years ended December 31, 1997 and 1998 was $16,000 and $4,000, respectively. The
Company also recognized $11,912 and $34,592 of expense for Internet access

     On July 28, 1998, the Company entered into a new lease for office space,
which required the Company to provide a letter of credit for $160,000.
 
     Subsequent to yearend, the Company entered into a new lease agreement for
additional office space. The lease term is for 38 months and requires monthly
rental payments of approximately $20,500 plus variable operating expenses. This
commitment is included as a future minimum lease payment in the table above.
 
  LITIGATION
 
     In the normal course of business, the Company is subject to, and may become
a party to, litigation arising out of its operations. In management's opinion,
none of the matters currently in actual or threatened litigation will have a
material impact on the Company's financial position or results of operations.
 
  REVENUE SHARING AGREEMENTS
 
     On April 17, 1998, the Company and Netscape Communications Corporation
("Netscape") signed a strategic business agreement and trademark license
agreement (collectively, the "Agreement") to offer a free email service through
Netscape's portal site, Netscape Netcenter. The service is called Netscape
WebMail Powered by USA.NET. The Agreement is a revenue sharing arrangement
between the two companies that includes advertising and premium email service
revenue. Under the terms of the trademark license agreement, the Company made a
one-time non-refundable payment of $5 million. In addition, each party has
obligations with regard to performance and marketing. The Company's rights under
the Agreement may be terminated if the Company does not meet such performance
criteria or under other specified conditions.
 
     On October 31, 1998, the Company and Netscape signed an addendum to the
Agreement to expand the territory in which Netscape WebMail Powered by USA.NET
will be offered. Such service may now be offered in specified foreign countries
and is subject to a revenue sharing arrangement between the two companies. Under
the terms of the addendum, the Company made an additional one-time
non-refundable payment of $1.5 million. The Company may be committed to pay an
additional $625,000 and $375,000 to Netscape in 1999 and 2000, respectively,
subject to the completion of certain tasks by Netscape. Such tasks were not
complete at December 31, 1998.
 
     The Agreements were entered into by the Company primarily to gain access to
Netscape's customers and for general strategic marketing purposes. The Company's
policy with regard to channel acquisition agreements is to capitalize costs to
acquire access to customers if the arrangement contains guarantees of minimum
revenue which support the amount paid. Because the Agreements do not contain
minimum guaranteed revenue, and due to the start-up nature of this service and
other uncertainties around this arrangement, the Company has expensed the
payments to Netscape.
 
     On April 8, 1997, the Company entered into an agreement with a certain
holder of its preferred stock, in which the Company provides co-branded,
advertising supported email services. Under the terms of the agreement, the
Company must remit to the investor a percentage of gross revenues, as defined,
generated from the use of this service. Through December 31, 1998, no material
payments were due under the agreement.

Agreement, Investor Rights Agreement and Co-Marketing Program Agreement
(collectively the "Series B Agreement") under which it sold 527,579 shares of

respectively. Any cash not used for this specified purpose becomes unrestricted
between April 1999 and March 2000, or the termination of the Series B Agreement,
whichever is earlier.
 
     In connection with the Series B Agreement, an officer of the Company has
entered into a stock restriction agreement. Shares of common stock and Series A
held by the officer at the time of issuance of the Series B are subject to
repurchase by the Company in the event that such officer is terminated for cause
or voluntarily ceases to be an employee, director or consultant prior to April
8, 2000. The repurchase price is $0.57 per share for common stock and $4.76 per

Purchase Agreement and an Investor Rights Agreement with various purchasers
pursuant to which it sold 736,376 shares of Series C for $6.79 per share for
proceeds of $4,999,995. In addition, the Company entered into a Co-Marketing
Program Agreement with one of those investors. These three agreements are
collectively referred to as the Series C Agreement. The Series C Agreement also
granted the purchasers an option to purchase a minimum of 98,085 to 490,426
shares (dependent upon the number of purchasers who exercise the option) and up
to a maximum of 736,376 shares of Series C at a price of $6.79 per share. The
option was exercised on March 23, 1998 with regard to 736,376 shares at $6.79
per share for total proceeds of $4,999,993. On March 23, 1998 and May 13, 1998,

respectively, at $6.79 per share for proceeds of $3,306,173 and $502,460,
respectively, to various Series C stockholders and other investors.

proceeds from the sale of Series C in October 1997 and $1,000,000 from the sale
on March 23, 1998, for marketing and technical development efforts as specified

     In August 1998, the Company entered into a Series D Preferred Stock
Purchase Agreement and Investor Rights Agreement (collectively the "Series D
Agreement") with various purchasers pursuant to which it sold 1,557,318 shares
of Series D for $14.75 per share for proceeds of $22,970,441 (prior to offering
costs of $1,894,052, including $313,251 for the issuance of the warrant
discussed below).
 
     The holders of Series Preferred have various rights and preferences as
follows:
 
     Conversion
 
     The holders of the Series Preferred may, at the option of the holder, be
converted at any time into shares of common stock at a current conversion rate
of one share of common stock for each share of Series Preferred. The conversion
ratios will be adjusted in certain circumstances, primarily to prevent dilution.
Additionally, each share of Series Preferred will automatically convert into
shares of common stock based on the then current conversion rate (i) at any time
upon the affirmative election of the holders of at least 70% of the outstanding
shares of Series Preferred or (ii) upon the closing of a firmly underwritten
public offering of the common stock of not less than $20 million (before
deduction of underwriters' discounts, commissions and fees) and which results in
a per share price of at least 150% of the then applicable price at which the
Series D converts into common stock.
 
     Voting
 
     The Series Preferred are voted equally with the shares of common stock of
the Company, on an as-if converted to common stock basis.
 
     Dividends
 
     Holders of the Series B, C and D are entitled to receive on a pari passu
basis non-cumulative dividends in preference to any dividend payable on the
Series A and the common stock at the rate of 6% of the original purchase for
each Series price per annum, when, as and if declared by the Board of Directors.
After such payment, the holders of Series A are entitled to receive
non-cumulative dividends in preference to any dividends payable on common stock,
at the rate of 6% of the stated value ($4.76) per annum, when, as and if
declared by the Board of Directors. The holders of Series B, C and D are also
entitled to participate pro rata in any dividends paid on the Series A or common
stock, on an as-if converted basis. The holders of Series A are also entitled to
participate in any dividends paid on the common stock on an as-if converted
basis. No dividends on Series Preferred or common stock have been declared by
the Board of Directors.
 
     The Series B and C Agreements also require the prior approval of the
Director representative of the Series B and C to the Company's Board of
Directors prior to the Company issuing any debt security in excess of 50% of the
Company's equity at the closing of such financing, acquiring or obtaining a 10%
or greater interest in any other corporation, partnership or entity, declaring
or paying dividends on shares of common stock other than in compliance with the
Restated Certificate, or selling additional shares of Series B or C,
respectively. The rights terminate with respect to the Series B when the
original holders of Series B no longer hold at least 250,000 shares of Series B
and with respect to the Series C when there are no longer 250,000 shares of
Series C outstanding.
 
     Liquidation
 
     In the event of any liquidation, dissolution or winding up of the Company,
whether voluntary or involuntary, including a merger, acquisition, sale of
voting control or sale of substantially all of the assets of the Company in
which the stockholders of the Company do not own a majority of the outstanding
shares of the surviving corporation, the holders of the Series D shall be
entitled to receive in preference to

the holders of the Series A, B and C and the common stock, $14.75 per share plus
any declared but unpaid dividends. After distribution of such amounts to the
holders of Series D, the holders of Series B and Series C shall be entitled to
receive on a pari passu basis $5.69 and $6.79 per share, respectively, plus any
declared but unpaid dividends. After distribution of such amounts, the holders
of Series A will be entitled to receive $4.76 per share plus any declared but
unpaid dividends. Following such distributions, the remaining assets shall be
distributed ratably to the holders of the common stock provided, however, that
the Series Preferred will be entitled to participate in distributions to the
common stockholders such that, after giving effect to the applicable liquidation
preferences of each series, the holders of each series of Series Preferred shall
receive aggregate distributions equal to the greater of (i) the liquidation
preference applicable to such series and (ii) the amount such holders would have
received if their shares of Series Preferred had been converted into common
stock immediately prior to such liquidation, dissolution or winding up of the
Company. If the Company's assets are insufficient to repay any such amounts, as
described above, the remaining assets will be distributed ratably, in order of
liquidation preference.
 
  WARRANT

under which the Company is authorized to grant incentive and non-qualified stock

employees and directors of the Company. Under the Plan, the exercise price per
share of a non-qualified stock option must be equal to at least 50% of the fair
market value of the common stock on the date of grant, and the exercise price
per share of an incentive stock option must equal the fair market value of the
common stock on the date of grant. Options granted vest over various terms with
a maximum vesting period of five years and expire after a maximum of 10 years.
The Company accounts for the Plan under APB Opinion No. 25, under which no
compensation cost has been recognized in the accompanying financial statements.

     The Company terminated its S corporation status effective February 28,
1997. Because the Company incurred losses prior to this date, there is no pro
forma income tax provision/benefit, as the Company's history of operating losses
result in no benefit being recorded for such losses. Tax net operating losses
incurred during this period are not available to offset the Company's future
taxable income, if any.

     At December 31, 1998, for income tax purposes, the Company has
approximately $18,779,000 of net operating loss carryforwards for the period
from March 1, 1997 through December 31, 1998. Such net operating losses begin
expiring in 2012. The net operating loss for tax purposes differs from that for
financial reporting purposes due to differences in reporting certain
transactions for income tax and financial reporting purposes.
 
     The Tax Reform Act of 1986 contains provisions which may limit the net
operating loss carryforwards available to be used in any given year if certain
events occur, including significant changes in ownership interests.
 
     No provision or benefit (actual or pro forma) has been recorded for any
period presented due to the Company's history of net losses.
 
     The Company has determined that approximately $1,571,000 and $8,800,000 of
net deferred tax assets at December 31, 1997 and 1998, did not satisfy the
realization criteria set forth in SFAS No. 109, "Accounting for Income Taxes."
Management believes, that based on all available evidence, it is more likely
than not that the deferred tax assets will not be realized. Accordingly, a
valuation allowance was recorded against the entire net deferred tax asset.
 
(9) DISCONTINUED OPERATION
 
     In March 1997, the Company sold its ISP business segment in order to focus
its resources on its Internet email business. This business segment was sold to
an entity in which certain significant stockholders of the Company hold a
substantial interest. The Company has no interest in, and does not exercise
influence over, the ISP.
 
     The ISP business segment was sold for a promissory note of $925,000, which
was collected in full during 1997, and the assumption of a note payable of
$324,760. The gain on the sale of the Internet

Note 5).
 
  1997 STOCK OPTION PLAN
 
     At March 19, 1999, the Company had granted stock options under the Plan to
purchase an aggregate of approximately 983,150 shares of common stock, of which
options to purchase approximately 17,400 shares had been exercised, options to
purchase approximately 164,400 shares had been forfeited or cancelled and
options to purchase approximately 801,350 shares at a weighted average exercise
price of approximately $3.55 per share remained outstanding. As discussed below,
the Company will make no future grants under the Plan.
 
  1999 EQUITY INCENTIVE PLAN

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  1999 EMPLOYEE STOCK PURCHASE PLAN
 
     On April 1, 1999 the Board of Directors approved the 1999 Employee Stock
Purchase Plan (the "Purchase Plan"). The Purchase Plan will become effective on
the effective date of the initial public offering of the Company's common stock.
The Purchase Plan is intended to qualify as an "employee stock purchase plan"
within the meaning of Section 423 of the Internal Revenue Code. The first
offering under the Purchase Plan will begin on the effective date of the initial
public offering of the Company's common stock, with the first purchase date
being December 31, 1999. Unless otherwise determined, common stock is purchased
under the Purchase Plan at a price per share equal to the lower of (i) 85% of
the fair market value of a share of common stock on the commencement date of the
offering or (ii) 85% of the fair market value of a share of common stock on the
date of purchase. Generally, all regular employees, including executive
officers, may participate in the Purchase Plan and may authorize payroll
deductions for the purchase of stock. The Purchase Plan will terminate at the
Board of Directors direction or when all of the shares reserved for issuance
have been purchased.
 
  INITIAL PUBLIC OFFERING
 
     On April 5, 1999, the Company filed a registration statement with the SEC
on Form S-1.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Our amended and restated bylaws that will become effective upon the closing
of this offering provide that we will indemnify our directors and executive
officers to the fullest extent permitted by Delaware law and may indemnify our
other officers, employees and other agents to the fullest extent permitted by
Delaware law.
 
     In addition, our restated certificate of incorporation that will become
effective upon the closing of this offering provides that, to the fullest extent
permitted by Delaware law, our directors will not be personally liable to us or
our stockholders for monetary damages for any breach of fiduciary duty as
directors. This provision of the restated certificate of incorporation does not
eliminate the directors' duty of care. In appropriate circumstances, equitable
remedies such as an injunction or other forms of non-monetary relief are
available under Delaware law. This provision also does not affect the directors'
responsibilities under any other laws, such as the federal securities laws and
state and federal environmental laws.
 
     Each director will continue to be subject to liability for:
 
     - Breach of a director's duty of loyalty to us and our stockholders;
 
     - Acts or omissions not in good faith or that involve intentional
       misconduct or a knowing violation of law;
 
     - Unlawful payments of dividends or unlawful stock repurchases or
       redemptions; and
 
     - Any transaction from which a director derived an improper personal
       benefit.
 
     We also intend to enter into indemnity agreements with our directors and
executive officers. We have purchased liability insurance for our directors and
executive officers.
 
     There is no pending litigation or proceeding involving any of our directors
or officers as to which indemnification is being sought. We are not aware of any
pending or threatened litigation that may result in a claim for indemnification.

ITEM 17. UNDERTAKINGS.
 
     The undersigned registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreement certificates in such

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to provisions described in Item 14 or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
 
     The undersigned registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this registration statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

shares of Preferred Stock are hereby designated "Series A Preferred Stock" (the

collectively referred to as the "Series Preferred."

         D. The rights, preferences, privileges, restrictions and other matters
relating to the Series Preferred are as follows:

            1. DIVIDEND RIGHTS.

               a. Holders of Series B  Preferred,  Series C Preferred and Series
D Preferred, in preference to the holders of Series A Preferred and Common Stock
of the Company shall be entitled to receive, when and as declared by the Board
of Directors, but only out of funds that are legally available therefor, cash
dividends at the rate of six percent (6%) of the Original Issue Price per annum
on each outstanding share of Series B Preferred, Series C Preferred and Series D
Preferred (as adjusted for any stock dividends, combinations, splits,
recapitalizations and the like with respect to such shares). Such dividends
shall be payable only when, as and if declared by the Board of Directors and
shall be non-cumulative from the Original Issue Date of the Series D Preferred
(as defined in Section 4(e) below). The Original Issue Price of the Series B
Preferred shall be Five Dollars Sixty-Nine Cents ($5.69), the Original Issue
Price of the Series C Preferred shall be Six Dollars Seventy-Nine Cents ($6.79)
and the Original Issue Price of the Series D Preferred shall be Fourteen Dollars
Seventy-Five Cents ($14.75). So long as any shares of Series B Preferred, Series
C Preferred or Series D Preferred shall be outstanding, no dividend, whether in
cash or property, shall be paid or declared, nor shall any other distribution be
made, on any other series of Preferred Stock ranking junior to the Series B
Preferred, Series C Preferred or Series D Preferred with respect to dividends or
on any Common Stock, nor shall any shares of Preferred Stock ranking junior to
the Series B Preferred, Series C Preferred or Series D Preferred with respect to
dividends or any Common Stock be purchased, redeemed, or otherwise acquired for
value by the Company (except for acquisitions of Common Stock by the Company
pursuant to agreements which permit the Company to repurchase such shares upon
termination of services to the Company or in exercise of the Company's right of
first refusal upon a proposed transfer) until all dividends on the Series B
Preferred, 




                                       2
<PAGE>   3

Series C Preferred and Series D Preferred shall have been paid or declared and
set apart. In the event dividends are paid on any share of Series A Preferred or
Common Stock, an additional dividend shall be paid with respect to all
outstanding shares of Series B Preferred, Series C Preferred and Series D
Preferred in an amount equal per share (on an as-if-converted to Common Stock
basis) to the amount paid or set aside for each share of Series A Preferred or
Common Stock.

               b. Holders of Series A Preferred, in preference to the holders of
Common Stock of the Company shall be entitled to receive, when and as declared
by the Board of Directors, but only out of funds that are legally available
therefor, cash dividends at the rate of six percent (6%) of the Original Issue
Price per annum on each outstanding share of Series A Preferred (as adjusted for
any stock dividends, combinations, splits, recapitalizations and the like with
respect to such shares). Such dividends shall be payable only when, as and if
declared by the Board of Directors and shall be non-cumulative from the Original
Issue Date. The Original Issue Price of the Series A Preferred shall be Four
Dollars Seventy-Six Cents ($4.76). So long as any shares of Series A Preferred
shall be outstanding, no dividend, whether in cash or property, shall be paid or
declared, nor shall any other distribution be made, on any other series of
Preferred Stock ranking junior to the Series A Preferred with respect to
dividends or on any Common Stock, nor shall any shares of Preferred Stock
ranking junior to the Series A Preferred with respect to dividends or any Common
Stock be purchased, redeemed, or otherwise acquired for value by the Company
(except for acquisitions of Common Stock by the Company pursuant to agreements
which permit the Company to repurchase such shares upon termination of services
to the Company or in exercise of the Company's right of first refusal upon a
proposed transfer) until all dividends on the Series A Preferred shall have been
paid or declared and set apart. In the event dividends are paid on any share of
Common Stock, an additional dividend shall be paid with respect to all
outstanding shares of Series A Preferred in an amount equal per share (on an
as-if-converted to Common Stock basis) to the amount paid or set aside for each
share of Common Stock.

               c. The provisions of Section 1(a) and 1(b) shall not, however,
apply to (i) a dividend payable in Common Stock, (ii) the acquisition of shares
of any capital stock of the Company in exchange for shares of any other capital
stock of the Company, or (iii) (A) any repurchase of any outstanding securities
of the Company that is unanimously approved by the Company's Board of Directors,
or (B) any repurchase of any outstanding securities by the Company pursuant to
the Second Amended and Restated Investor Rights Agreement dated on or about
August 11, 1998, as amended from time to time.

            2. VOTING RIGHTS. Except as otherwise provided by law or
elsewhere herein, the Series Preferred shall be voted equally with the shares of
the Common Stock of the Company and not as a separate class, at any annual or
special meeting of stockholders of the Company, and may act by written consent
in the same manner as the Common Stock, in either case upon the following basis:
each holder of shares of Series Preferred shall be entitled to such number of
votes as shall be equal to the whole number of shares of Common Stock into which
such holder's aggregate number of shares of Series Preferred are convertible
(pursuant to Section 4 hereof) immediately after the close of business on the
record date fixed for such meeting or the effective date of such written
consent.

               3. LIQUIDATION RIGHTS.

                  a. Upon any liquidation, dissolution, or winding up of the
Company, whether voluntary or involuntary, before any distribution or payment
shall be made to the holders of Series A Preferred, Series B Preferred, Series C
Preferred or Common Stock, the holders of Series D Preferred shall be entitled
to be paid out of the assets of the Company an amount per share equal to the sum
of the Original Issue Price of the Series D Preferred plus all declared and
unpaid dividends on the Series D Preferred (as adjusted for stock dividends,
combinations, splits, recapitalizations and the like with respect to such
shares) (the "Series D Preferred Liquidation Value"). If, upon any liquidation,
dissolution or winding up, the assets of the Company shall be insufficient to
make payment in full to all holders of Series D Preferred of the Series D
Liquidation Value, then such assets shall be distributed among the holders of
Series D Preferred at the time outstanding, ratably in proportion to the full
amounts to which they would otherwise be entitled.

                  b. Upon any liquidation, dissolution, or winding up of the
Company, whether voluntary or involuntary, after the distribution has been made
pursuant to Section 3(a) above, and before any distribution or payment shall be
made to the holders of Series A Preferred or Common Stock, the holders of Series
B Preferred and Series C Preferred shall be entitled to be paid out of the
assets of the Company an amount per share of Series B Preferred and Series C
Preferred equal to (i) with respect to the Series B Preferred, the sum of the
Original Issue Price of the Series B Preferred plus all declared and unpaid
dividends on the Series B Preferred (as adjusted for stock 



                                       6
<PAGE>   7

dividends, combinations, splits, recapitalizations and the like with respect to
such shares) (the "Series B Preferred Liquidation Value") and (ii) with respect
to the Series C Preferred, the sum of the Original Issue Price of the Series C
Preferred plus all declared and unpaid dividends on the Series C Preferred (as
adjusted for stock dividends, combinations, splits, recapitalizations and the
like with respect to such shares) (the "Series C Preferred Liquidation Value").
If, upon any liquidation, dissolution or winding up, the assets of the Company
shall be insufficient to make payment in full to all holders of Series B
Preferred and Series C Preferred of the liquidation preferences set forth in
this Section 3(b), then such assets shall be distributed among the holders of
Series B Preferred and Series C Preferred at the time outstanding, ratably in
proportion to the full amounts to which they would otherwise be respectively
entitled.

                  c. Upon any liquidation, dissolution, or winding up of the
Company, whether voluntary or involuntary, after the distributions have been
made pursuant to Sections 3(a) and 3(b) above, and before any distribution or
payment shall be made to the holders of any Common Stock, the holders of Series
A Preferred shall be entitled to be paid out of the assets of the Company an
amount per share of Series A Preferred equal to the Original Issue Price of the
Series A Preferred plus all declared and unpaid dividends on the Series A
Preferred (as adjusted for stock dividends, combinations, splits,
recapitalizations and the like with respect to such shares) (the "Series A
Preferred Liquidation Value"). If, upon any liquidation, dissolution or winding
up, the assets of the Company shall be insufficient to make payment in full to
all holders of Series A Preferred of the Series A Preferred Liquidation Value,
then such assets shall be distributed among the holders of Series A Preferred at
the time outstanding, ratably in proportion to the full amounts to which they
would otherwise be entitled.

                  d. After the payment of the full liquidation preferences of
the Series D Preferred as set forth in Section 3(a) above, the Series B
Preferred and Series C Preferred as set forth in Section 3(b) above and the
Series A Preferred as set forth in Section 3(c) above, the remaining assets of
the Company legally available for distribution, if any, shall be distributed
ratably to the holders of the Common Stock. The holders of Series Preferred
shall be entitled to participate in distributions to holders of the Common Stock
such that, after giving effect to all distributions pursuant to Section 3(a),
3(b) and 3(c), the holders of Series Preferred receive aggregate distributions
equal to the greater of the Series D Preferred Liquidation Value, Series C
Preferred Liquidation Value, Series B Preferred Liquidation Value or Series A
Preferred Liquidation Value, as applicable, and the amounts such holders would
have received if the Series D Preferred, Series C Preferred, Series B Preferred
or Series A Preferred had been converted into Common Stock immediately prior to
such liquidation, dissolution or winding up of the Company.

                  e. The following events shall be considered a liquidation
under this Section:

                     (i) any consolidation or merger of the Company with or into
any other corporation or other entity or person, or any other corporate
reorganization, in which the stockholders of the Company immediately prior to
such consolidation, merger or reorganization, own less than 50% of the Company's
voting power immediately after such consolidation, merger or 




                                       7
<PAGE>   8

reorganization, or any transaction or series of related transactions in which in
excess of fifty percent (50%) of the Company's voting power is transferred (an
"Acquisition"); or

                     (ii) a sale, lease or other disposition of all or
substantially all of the assets of the Company (an "Asset Transfer").

               4. CONVERSION RIGHTS.

               The holders of the Series Preferred shall have the following
rights with respect to the conversion of the Series Preferred into shares of
Common Stock (the "Conversion Rights"):

                  a. OPTIONAL CONVERSION. Subject to and in compliance with the
provisions of this Section 4, any shares of Series Preferred may, at the option
of the holder, be converted at any time into fully-paid and nonassessable shares
of Common Stock. The number of shares of Common Stock to which a holder of
Series Preferred shall be entitled upon conversion shall be the product obtained
by multiplying the applicable "Series Conversion Rate" then in effect
(determined as provided in Section 4(b)) by the number of shares of Series
Preferred being converted.

                  b. CONVERSION RATE. The conversion rate in effect at any time
for conversion of the Series A Preferred (the "Series A Preferred Conversion
Rate") shall be the quotient obtained by dividing the Original Issue Price of
the Series A Preferred by the "Series A Preferred Price," calculated as provided
in Section 4(c). The conversion rate in effect at any time for conversion of the
Series B Preferred (the "Series B Preferred Conversion Rate") shall be the
quotient obtained by dividing the Original Issue Price of the Series B Preferred
by the "Series B Preferred Price," calculated as provided in Section 4(c). The
conversion rate in effect at any time for conversion of the Series C Preferred
(the "Series C Preferred Conversion Rate") shall be the quotient obtained by
dividing the Original Issue Price of the Series C Preferred by the "Series C
Preferred Price," calculated as provided in Section 4(c). The conversion rate in
effect at any time for conversion of the Series D Preferred (the "Series D
Preferred Conversion Rate") shall be the quotient obtained by dividing the
Original Issue Price of the Series D Preferred by the "Series D Preferred
Price," calculated as provided in Section 4(c).

                  c. CONVERSION PRICE. The conversion price for the Series A
Preferred shall initially be the Original Issue Price of the Series A Preferred
(the "Series A Preferred Price"). The conversion price for the Series B
Preferred shall initially be the Original Issue Price of the Series B Preferred
(the "Series B Preferred Price"). The conversion price for the Series C
Preferred shall initially be the Original Issue Price of the Series C Preferred
(the "Series C Preferred Price"). The conversion price for the Series D
Preferred shall initially be the Original Issue Price of the Series D Preferred
(the "Series D Preferred Price"). The Series A Preferred Price, Series B
Preferred Price, Series C Preferred Price and Series D Preferred Price shall
collectively be referred to as the "Preferred Prices," and each a "Preferred
Price." Such initial Preferred Prices shall be adjusted from time to time in
accordance with this Section 4. All references to each Preferred Price herein
shall mean such Preferred Price as so adjusted.




                                       8
<PAGE>   9

                  d. MECHANICS OF CONVERSION. Each holder of Series Preferred
who desires to convert the same into shares of Common Stock pursuant to this
Section 4 shall surrender the certificate or certificates therefor, duly
endorsed, at the office of the Company or any transfer agent for the Series
Preferred, and shall give written notice to the Company at such office that such
holder elects to convert the same. Such notice shall state the number of shares
of Series Preferred being converted. Thereupon, the Company shall promptly issue
and deliver at such office to such holder a certificate or certificates for the
number of shares of Common Stock to which such holder is entitled and shall
promptly pay in cash or, to the extent sufficient funds are not then legally
available therefor, in Common Stock (at the Common Stock's fair market value
determined by the Board of Directors as of the date of such conversion), any
declared and unpaid dividends on the shares of Series Preferred being converted.
Such conversion shall be deemed to have been made at the close of business on
the date of such surrender of the certificates representing the shares of Series
Preferred to be converted, and the person entitled to receive the shares of
Common Stock issuable upon such conversion shall be treated for all purposes as
the record holder of such shares of Common Stock on such date.

                  e. ADJUSTMENT FOR STOCK SPLITS AND COMBINATIONS. If the
Company shall at any time or from time to time after the date that the first
share of Series D Preferred is issued (the "Original Issue Date") effect a
subdivision of the outstanding Common Stock without a corresponding subdivision
of the Preferred Stock, the applicable Preferred Price in effect immediately
before that subdivision shall be proportionately decreased. Conversely, if the
Company shall at any time or from time to time after the Original Issue Date
combine the outstanding shares of Common Stock into a smaller number of shares
without a corresponding combination of the Preferred Stock, the applicable
Preferred Price in effect immediately before the combination shall be
proportionately increased. Any adjustment under this Section 4(e) shall become
effective at the close of business on the date the subdivision or combination
becomes effective.

                  f. ADJUSTMENT FOR COMMON STOCK DIVIDENDS AND DISTRIBUTIONS. If
the Company at any time or from time to time after the Original Issue Date
makes, or fixes a record date for the determination of holders of Common Stock
entitled to receive, a dividend or other distribution payable in additional
shares of Common Stock, in each such event the applicable Preferred Price that
is then in effect shall be decreased as of the time of such issuance or, in the
event such record date is fixed, as of the close of business on such record
date, by multiplying the applicable Preferred Price then in effect by a fraction
(1) the numerator of which is the total number of shares of Common Stock issued
and outstanding immediately prior to the time of such issuance or the close of
business on such record date, and (2) the denominator of which is the total
number of shares of Common Stock issued and outstanding immediately prior to the
time of such issuance or the close of business on such record date plus the
number of shares of Common Stock issuable in payment of such dividend or
distribution; provided, however, that if such record date is fixed and such
dividend is not fully paid or if such distribution is not fully made on the date
fixed therefor, the applicable Preferred Price shall be recomputed accordingly
as of the close of business on such record date and thereafter the applicable
Preferred Price shall be adjusted pursuant to this Section 4(f) to reflect the
actual payment of such dividend or distribution.



                                       9
<PAGE>   10
                  g. ADJUSTMENTS FOR OTHER DIVIDENDS AND DISTRIBUTIONS. If the
Company at any time or from time to time after the Original Issue Date makes, or
fixes a record date for the determination of holders of Common Stock entitled to
receive, a dividend or other distribution payable in securities of the Company
other than shares of Common Stock, in each such event provision shall be made so
that the holders of the Series Preferred shall receive upon conversion thereof,
in addition to the number of shares of Common Stock receivable thereupon, the
amount of other securities of the Company which they would have received had
their Series Preferred been converted into Common Stock on the date of such
event and had they thereafter, during the period from the date of such event to
and including the conversion date, retained such securities receivable by them
as aforesaid during such period, subject to all other adjustments called for
during such period under this Section 4 with respect to the rights of the
holders of the Series Preferred or with respect to such other securities by
their terms.

                  h. ADJUSTMENT FOR RECLASSIFICATION, EXCHANGE AND SUBSTITUTION.
If at any time or from time to time after the Original Issue Date, the Common
Stock issuable upon the conversion of the Series Preferred is changed into the
same or a different number of shares of any class or classes of stock, whether
by recapitalization, reclassification or otherwise (other than an Acquisition or
Asset Transfer as defined in Section 3(e) or a subdivision or combination of
shares or stock dividend or a reorganization, merger, consolidation or sale of
assets provided for elsewhere in this Section 4), in any such event each holder
of Series Preferred shall have the right thereafter to convert such stock into
the kind and amount of stock and other securities and property receivable upon
such recapitalization, reclassification or other change by holders of the
maximum number of shares of Common Stock into which such shares of Series
Preferred could have been converted immediately prior to such recapitalization,
reclassification or change, all subject to further adjustment as provided herein
or with respect to such other securities or property by the terms thereof.

                  i. REORGANIZATIONS, MERGERS, CONSOLIDATIONS OR SALES OF
ASSETS. If at any time or from time to time after the Original Issue Date, there
is a capital reorganization of the Common Stock (other than an Acquisition or
Asset Transfer as defined in Section 3(e)) or a recapitalization, subdivision,
combination, reclassification, exchange or substitution of shares provided for
elsewhere in this Section 4, as a part of such capital reorganization, provision
shall be made so that the holders of the Series Preferred shall thereafter be
entitled to receive upon conversion of the Series Preferred the number of shares
of stock or other securities or property of the Company to which a holder of the
number of shares of Common Stock deliverable upon conversion would have been
entitled on such capital reorganization, subject to adjustment in respect of
such stock or securities by the terms thereof. In any such case, appropriate
adjustment shall be made in the application of the provisions of this Section 4
with respect to the rights of the holders of Series Preferred after the capital
reorganization to the end that the provisions of this Section 4 (including
adjustment of the applicable Preferred Price then in effect and the number of
shares issuable upon conversion of the Series Preferred) shall be applicable
after that event and be as nearly equivalent as practicable.

<PAGE>   11
                  j. SALE OF SHARES BELOW APPLICABLE PREFERRED PRICE.

                     (i) If at any time or from time to time after the Original
Issue Date, the Company issues or sells, or is deemed by the express provisions
of this subsection (j) to have issued or sold, Additional Shares of Common Stock
(as defined in subsection (j)(iv) below), other than as a dividend or other
distribution on any class of stock as provided in Section 4(f) above, and other
than a subdivision or combination of shares of Common Stock as provided in
Section 4(e) above, for an Effective Price (as defined in subsection (j)(iv)
below) less than the then effective applicable Preferred Price, then and in each
such case the then existing applicable Preferred Price shall be reduced, as of
the opening of business on the date of such issue or sale, to a price determined
by multiplying the applicable Preferred Price by a fraction (i) the numerator of
which shall be (A) the number of shares of Common Stock deemed outstanding (as
defined below) immediately prior to such issue or sale, plus (B) the number of
shares of Common Stock which the aggregate consideration received (as defined in
subsection (j)(ii)) by the Company for the total number of Additional Shares of
Common Stock so issued would purchase at such applicable Preferred Price, and
(ii) the denominator of which shall be the number of shares of Common Stock
deemed outstanding (as defined below) immediately prior to such issue or sale
plus the total number of Additional Shares of Common Stock so issued. For the
purposes of the preceding sentence, the number of shares of Common Stock deemed
to be outstanding as of a given date shall be the sum of (A) the number of
shares of Common Stock actually outstanding, (B) the number of shares of Common
Stock into which the then outstanding shares of Series Preferred could be
converted if fully converted on the day immediately preceding the given date,
and (C) the number of shares of Common Stock which could be obtained through the
exercise or conversion of all other rights, options and convertible securities
outstanding on the day immediately preceding the given date whether or not then
exercisable.

                     (ii) For the purpose of making any adjustment required
under this Section 4(j), the consideration received by the Company for any issue
or sale of securities shall (A) to the extent it consists of cash, be computed
at the net amount of cash received by the Company after deduction of any
underwriting or similar commissions, compensation or concessions paid or allowed
by the Company in connection with such issue or sale but without deduction of
any expenses payable by the Company, (B) to the extent it consists of property
other than cash, be computed at the fair value of that property as determined in
good faith by the Board of Directors, and (C) if Additional Shares of Common
Stock, Convertible Securities (as defined in subsection (j)(iii)) or rights or
options to purchase either Additional Shares of Common Stock or Convertible
Securities are issued or sold together with other stock or securities or other
assets of the Company for a consideration which covers both, be computed as the
portion of the consideration so received that may be reasonably determined in
good faith by the Board of Directors to be allocable to such Additional Shares
of Common Stock, Convertible Securities or rights or options.

                     (iii) For the purpose of the adjustment required under this
Section 4(j), if the Company issues or sells any rights or options for the
purchase of, or stock or other securities convertible into, Additional Shares of
Common Stock (such convertible stock or securities being herein referred to as
"Convertible Securities") and if the Effective Price of such Additional Shares
of Common Stock is less than the applicable Preferred Price, in each case the





                                       11
<PAGE>   12
Company shall be deemed to have issued at the time of the issuance of such
rights or options or Convertible Securities the maximum number of Additional
Shares of Common Stock issuable upon exercise or conversion thereof and to have
received as consideration for the issuance of such shares an amount equal to the
total amount of the consideration, if any, received by the Company for the
issuance of such rights or options or Convertible Securities, plus, in the case
of such rights or options, the minimum amounts of consideration, if any, payable
to the Company upon the exercise of such rights or options, plus, in the case of
Convertible Securities, the minimum amounts of consideration, if any, payable to
the Company (other than by cancellation of liabilities or obligations evidenced
by such Convertible Securities) upon the conversion thereof; provided that, if
in the case of Convertible Securities, the minimum amounts of such consideration
cannot be ascertained, but are a function of antidilution or similar protective
clauses, the Company shall be deemed to have received the minimum amounts of
consideration without reference to such clauses; provided further that, if the
minimum amount of consideration payable to the Company upon the exercise or
conversion of rights, options or Convertible Securities is reduced over time or
on the occurrence or non-occurrence of specified events other than by reason of
antidilution adjustments, the Effective Price shall be recalculated using the
figure to which such minimum amount of consideration is reduced; provided
further that, if the minimum amount of consideration payable to the Company upon
the exercise or conversion of such rights, options or Convertible Securities is
subsequently increased, the Effective Price shall be again recalculated using
the increased minimum amount of consideration payable to the Company upon the
exercise or conversion of such rights, options or Convertible Securities. No
further adjustment of the applicable Preferred Price, as adjusted upon the
issuance of such rights, options or Convertible Securities, shall be made as a
result of the actual issuance of Additional Shares of Common Stock on the
exercise of any such rights or options or the conversion of any such Convertible
Securities. If any such rights or options or the conversion privilege
represented by any such Convertible Securities shall expire without having been
exercised, the applicable Preferred Price as adjusted upon the issuance of such
rights, options or Convertible Securities shall be readjusted to the applicable
Preferred Price which would have been in effect had an adjustment been made on
the basis that the only Additional Shares of Common Stock so issued were the
Additional Shares of Common Stock, if any, actually issued or sold on the
exercise of such rights or options or rights of conversion of such Convertible
Securities, and such Additional Shares of Common Stock, if any, were issued or
sold for the consideration actually received by the Company upon such exercise,
plus the consideration, if any, actually received by the Company for the
granting of all such rights or options, whether or not exercised, plus the
consideration received for issuing or selling the Convertible Securities
actually converted, plus the consideration, if any, actually received by the
Company (other than by cancellation of liabilities or obligations evidenced by
such Convertible Securities) on the conversion of such Convertible Securities,
provided that such readjustment shall not apply to prior conversions of Series
Preferred.

                     (iv) "Additional Shares of Common Stock" shall mean all
shares of Common Stock issued by the Company or deemed to be issued pursuant to
this Section 4(j), whether or not subsequently reacquired or retired by the
Company other than (1) shares of Common Stock issued upon conversion of the
Series Preferred; (2) shares of Common Stock and/or options, warrants or other
Common Stock purchase rights, and the Common Stock issued pursuant to such
options, warrants or other rights (as adjusted for any stock dividends,
combinations, splits, 




                                       12
<PAGE>   13

recapitalizations and the like) (collectively, the "Option Shares") after the
Original Issue Date to employees, officers or directors of, or consultants or
advisors to the Company or any subsidiary pursuant to stock purchase or stock
option plans or other arrangements that are approved by the Board, provided
that, the number of Option Shares issued pursuant to this clause (2) does not
exceed twenty percent (20%) of the total outstanding capital stock of the
Company (assuming conversion of all shares of Preferred Stock into Common Stock
and assuming the conversion or exercise of all options, warrants or other rights
to purchase capital stock of the Company, including the Option Shares issued);
(3) shares of Common Stock or Preferred Stock (and Common Stock issued or
issuable upon conversion of such Preferred Stock) issued pursuant to the
exercise of options, warrants or convertible securities outstanding as of the
Original Issue Date; (4) Common Stock or Convertible Securities issued for
consideration other than cash pursuant to a merger, consolidation, acquisition
or similar business combination; (5) shares of Common Stock issued upon the
exercise of the warrant held by BT Alex. Brown & Sons Incorporated and (6)
Common Stock or Convertible Securities issued pursuant to any equipment leasing
arrangement, or debt financing approved by the Board of Directors (collectively
the "Debt Financing Shares") from a bank or similar financial institution which
is not an affiliate of John Street; provided that the number of Debt Financing
Shares issued in all such transactions does not have an aggregate value in
excess of $250,000. The "Effective Price" of Additional Shares of Common Stock
shall mean the quotient determined by dividing the total number of Additional
Shares of Common Stock issued or sold, or deemed to have been issued or sold by
the Company under this Section 4(j), into the aggregate consideration received,
or deemed to have been received by the Company for such issue under this Section
4(j), for such Additional Shares of Common Stock.

                  k. CERTIFICATE OF ADJUSTMENT. In each case of an adjustment or
readjustment of the applicable Preferred Price for the number of shares of
Common Stock or other securities issuable upon conversion of the Series
Preferred, if the Series Preferred is then convertible pursuant to this Section
4, the Company, at its expense, shall compute such adjustment or readjustment in
accordance with the provisions hereof and prepare a certificate showing such
adjustment or readjustment, and shall mail such certificate, by first class
mail, postage prepaid, to each registered holder of Series Preferred at the
holder's address as shown in the Company's books. The certificate shall set
forth such adjustment or readjustment, showing in detail the facts upon which
such adjustment or readjustment is based, including a statement of (1) the
consideration received or deemed to be received by the Company for any
Additional Shares of Common Stock issued or sold or deemed to have been issued
or sold, (2) the Series Preferred Price at the time in effect, (3) the number of
Additional Shares of Common Stock and (4) the type and amount, if any, of other
property which at the time would be received upon conversion of the Series
Preferred.

                  l. NOTICES OF RECORD DATE. Upon (i) any taking by the Company
of a record of the holders of any class of securities for the purpose of
determining the holders thereof who are entitled to receive any dividend or
other distribution, or (ii) any Acquisition (as defined in Section 3(e)) or
other capital reorganization of the Company, any reclassification or
recapitalization of the capital stock of the Company, any merger or
consolidation of the Company with or into any other corporation, or any Asset
Transfer (as defined in Section 3(e)), or any voluntary or involuntary
dissolution, liquidation or winding up of the Company, the Company shall mail to
each holder of Series Preferred at least twenty (20) days prior to the record
date specified therein a notice 





                                       13
<PAGE>   14

specifying (1) the date on which any such record is to be taken for the purpose
of such dividend or distribution and a description of such dividend or
distribution, (2) the date on which any such Acquisition, reorganization,
reclassification, transfer, consolidation, merger, Asset Transfer, dissolution,
liquidation or winding up is expected to become effective, and (3) the date, if
any, that is to be fixed as to when the holders of record of Common Stock (or
other securities) shall be entitled to exchange their shares of Common Stock (or
other securities) for securities or other property deliverable upon such
Acquisition, reorganization, reclassification, transfer, consolidation, merger,
Asset Transfer, dissolution, liquidation or winding up.

                  m. AUTOMATIC CONVERSION.

                     (i) Each share of Series Preferred shall automatically be 
converted into shares of Common Stock, based on the then-effective applicable
Preferred Price, (A) at any time upon the affirmative election of the holders of
at least seventy percent (70%) of the outstanding shares of Series Preferred
voting together as a single class, or (B) immediately upon the closing of a
firmly underwritten public offering pursuant to an effective registration
statement under the Securities Act of 1933, as amended, covering the offer and
sale of Common Stock for the account of the Company in which (i) the per share
price is at least one hundred fifty percent (150%) of the then applicable Series
D Preferred Price and (ii) the gross cash proceeds to the Company (before
underwriting discounts, commissions and fees) are at least Twenty Million
Dollars ($20,000,000). Upon such automatic conversion, any declared and unpaid
dividends shall be paid in accordance with the provisions of Section 4(d).

                     (ii) Upon the occurrence of the event specified in
paragraph (1) above, the outstanding shares of Series Preferred shall be
converted automatically without any further action by the holders of such shares
and whether or not the certificates representing such shares are surrendered to
the Company or its transfer agent; provided, however, that the Company shall not
be obligated to issue certificates evidencing the shares of Common Stock
issuable upon such conversion unless the certificates evidencing such shares of
Series Preferred are either delivered to the Company or its transfer agent as
provided below, or the holder notifies the Company or its transfer agent that
such certificates have been lost, stolen or destroyed and executes an agreement
satisfactory to the Company to indemnify the Company from any loss incurred by
it in connection with such certificates. Upon the occurrence of such automatic
conversion of the Series Preferred, the holders of Series Preferred shall
surrender the certificates representing such shares at the office of the Company
or any transfer agent for the Series Preferred. Thereupon, there shall be issued
and delivered to such holder promptly at such office and in its name as shown on
such surrendered certificate or certificates, a certificate or certificates for
the number of shares of Common Stock into which the shares of Series Preferred
surrendered were convertible on the date on which such automatic conversion
occurred, and any declared and unpaid dividends shall be paid in accordance with
the provisions of Section 4(d).

                  n. FRACTIONAL SHARES. No fractional shares of Common Stock
shall be issued upon conversion of Series Preferred. All shares of Common Stock
(including fractions thereof) issuable upon conversion of more than one share of
Series Preferred by a holder thereof shall be aggregated for purposes of
determining whether the conversion would result in the issuance 




                                       14
<PAGE>   15

of any fractional share. If, after the aforementioned aggregation, the
conversion would result in the issuance of any fractional share, the Company
shall, in lieu of issuing any fractional share, pay cash equal to the product of
such fraction multiplied by the Common Stock's fair market value (as determined
by the Board of Directors) on the date of conversion.

                  o. RESERVATION OF STOCK ISSUABLE UPON CONVERSION. The Company
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Series Preferred, such number of its shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Series Preferred. If at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then outstanding shares of the Series Preferred, the
Company will take such corporate action as may, in the opinion of its counsel,
be necessary to increase its authorized but unissued shares of Common Stock to
such number of shares as shall be sufficient for such purpose.

                  p. NOTICES. Any notice required by the provisions of this
Section 4 shall be in writing and shall be deemed effectively given: (i) upon
personal delivery to the party to be notified, (ii) when sent by confirmed telex
or facsimile if sent during normal business hours of the recipient; if not, then
on the next business day, (iii) five (5) days after having been sent by
registered or certified mail, return receipt requested, postage prepaid, or (iv)
one (1) day after deposit with a nationally recognized overnight courier,
specifying next day delivery, with written verification of receipt. All notices
shall be addressed to each holder of record at the address of such holder
appearing on the books of the Company.

                  q. PAYMENT OF TAXES. The Company will pay all taxes (other
than taxes based upon income) and other governmental charges that may be imposed
with respect to the issue or delivery of shares of Common Stock upon conversion
of shares of Series Preferred, excluding any tax or other charge imposed in
connection with any transfer involved in the issue and delivery of shares of
Common Stock in a name other than that in which the shares of Series Preferred
so converted were registered.

                  r. NO DILUTION OR IMPAIRMENT. Without the consent of the
holders of at least seventy percent (70%) of the outstanding Series Preferred,
the Company shall not amend its Restated Certificate of Incorporation or
participate in any reorganization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or take any other voluntary action, for
the purpose of avoiding or seeking to avoid the observance or performance of any
of the terms to be observed or performed under this Section 4 by the Company,
but shall at all times in good faith assist in carrying out all such action as
may be reasonably necessary or appropriate in order to protect the conversion
rights of the holders of the Series Preferred against dilution or other
impairment.

               5. NO REISSUANCE OF SERIES PREFERRED. No share or shares of
Series Preferred acquired by the Company by reason of redemption, purchase,
conversion or otherwise shall be reissued.



                                       15

               6. NO PREEMPTIVE RIGHTS. Stockholders shall have no preemptive
rights except as granted by the Company pursuant to written agreements.

                                       V.

      A. A director of the Company shall not be personally liable to the Company
or its stockholders for monetary damages for any breach of fiduciary duty as a
director, except for liability (i) for any breach of the director's duty of
loyalty to the Company or its stockholders, (ii) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the Delaware General Corporation Law, or (iv)
for any transaction from which the director derived an improper personal
benefit. If the Delaware General Corporation Law is amended after approval by
the stockholders of this Article V to authorize corporate action further
eliminating or limiting the personal liability of directors, then the liability
of a director shall be eliminated or limited to the fullest extent permitted by
the Delaware General Corporation Law, as so amended.

      B. Any repeal or modification of this Article V shall only be prospective
and shall not effect the rights under this Article V in effect at the time of
the alleged occurrence of any action or omission to act giving rise to
liability.

                                       VI.

      For the management of the business and for the conduct of the affairs of
the Company, and in further definition, limitation and regulation of the powers
of the Company, of its directors and of its stockholders or any class thereof,
as the case may be, it is further provided that:

      A. The management of the business and the conduct of the affairs of the
Company shall be vested in its Board of Directors. The number of directors which
shall constitute the whole Board of Directors shall be fixed by the Board of
Directors in the manner provided in the Bylaws.

      B. The Board of Directors may from time to time make, amend, supplement or
repeal the Bylaws; provided, however, that the stockholders may change or repeal
any Bylaw adopted by the Board of Directors by the affirmative vote of the
holders of a majority of the voting power of all of the then outstanding shares
of the capital stock of the Company; and, provided further, that no amendment or
supplement to the Bylaws adopted by the Board of Directors shall vary or
conflict with any amendment or supplement thus adopted by the stockholders.

      C. The directors of the Company need not be elected by written ballot
unless the Bylaws so provide.

                                     * * * *

      4. This Restated Certificate of Incorporation has been duly approved by
the Board of Directors of this Company.

accordance with the provisions of Sections 228, 242 and 245 of the General

of Incorporation by written consent in accordance with Section 228 of the

                          CERTIFICATE OF INCORPORATION
                                       OF
                                 USA.NET, INC.


                                       I.

         The name of this corporation is USA.NET, Inc.

                                      II.

         The address of the registered office of the corporation in the State
of Delaware is 1209 Orange Street, City of Wilmington, County of New Castle,
19801 and the name of the registered agent of the corporation in the State of
Delaware at such address is The Corporation Trust Company.

                                      III.

         The purpose of this corporation is to engage in any lawful act or
activity for which a corporation may be organized under the General Corporation
Law of the State of Delaware.

                                      IV.

         This corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock." The total number
of shares which the corporation is authorized to issue is ______________
(__________) shares. _______________ (_________) shares shall be Common Stock,
each having a par value of one-tenth of One Cent ($.001). ______________
(_________) shares shall be Preferred Stock, each having a par value of
one-tenth of One Cent ($.001).

         The Preferred Stock may be issued from time to time in one or more
series. The Board of Directors is hereby authorized, by filing a certificate (a
"Preferred Stock Designation") pursuant to the Delaware General Corporation Law
("DGCL"), to fix or alter from time to time the designation, powers,
preferences and rights of the shares of each such series and the
qualifications, limitations or restrictions of any wholly unissued series of
Preferred Stock, and to establish from time to time the number of shares
constituting any such series or any of them; and to increase or decrease the
number of shares of any series subsequent to the issuance of shares of that
series, but not below the number of shares of such series then outstanding. In
case the number of shares of any series shall be decreased in accordance with
the foregoing sentence, the shares constituting such decrease shall resume the
status that they had prior to the adoption of the resolution originally fixing
the number of shares of such series.


                                       1.

<PAGE>   3
                                       V.

         A.       For the management of the business and for the conduct of the
affairs of the Corporation, and in further definition, limitation and
regulation of the powers of the Corporation, of its directors and of its
stockholders or any class thereof, as the case may be, it is further provided
that:

                  1.      The management of the business and the conduct of the
affairs of the Corporation shall be vested in its Board of Directors. The
number of directors which shall constitute the whole Board of Directors shall
be fixed exclusively by one or more resolutions adopted by the Board of
Directors.

                  2.      Subject to the rights of the holders of any series of
Preferred Stock to elect additional directors under specified circumstances,
following the closing of the initial public offering pursuant to an effective
registration statement under the Securities Act of 1933, as amended, covering
the offer and sale of Common Stock to the public (the "Initial Public
Offering"), the directors shall be divided into three classes designated as
Class I, Class II and Class III, respectively. Directors shall be assigned to
each class in accordance with a resolution or resolutions adopted by the Board
of Directors. At the first annual meeting of stockholders following the closing
of the Initial Public Offering, the term of office of the Class I directors
shall expire and Class I directors shall be elected for a full term of three
years. At the second annual meeting of stockholders following the Closing of
the Initial Public Offering, the term of office of the Class II directors shall
expire and Class II directors shall be elected for a full term of three years.
At the third annual meeting of stockholders following the Closing of the
Initial Public Offering, the term of office of the Class III directors shall
expire and Class III directors shall be elected for a full term of three years.
At each succeeding annual meeting of stockholders, directors shall be elected
for a full term of three years to succeed the directors of the class whose
terms expire at such annual meeting.

         Notwithstanding the foregoing provisions of this Article, each
director shall serve until his successor is duly elected and qualified or until
such director's death, resignation or removal. No decrease in the number of
directors constituting the Board of Directors shall shorten the term of any
incumbent director.

                  3.      REMOVAL OF DIRECTORS

                          a.       Neither the Board of Directors nor any 
individual director may be removed without cause.

                          b.       Subject to any limitation  imposed by law,
any individual director or directors may be removed with cause by the
affirmative vote of the holders of a majority of the voting power of all the
then-outstanding shares of voting stock of the Corporation entitled to vote at
an election of directors (the "Voting Stock").

                  4.      VACANCIES

                          a.       Subject to the rights of the holders of any
series of Preferred Stock, any vacancies on the Board of Directors resulting
from death, resignation, disqualification,



                                       2.
<PAGE>   4

removal or other causes and any newly created directorships resulting from any
increase in the number of directors, shall, unless the Board of Directors
determines by resolution that any such vacancies or newly created directorships
shall be filled by the stockholders, except as otherwise provided by law, be
filled only by the affirmative vote of a majority of the directors then in
office, even though less than a quorum of the Board of Directors, and not by
the stockholders. Any director elected in accordance with the preceding
sentence shall hold office for the remainder of the full term of the director
for which the vacancy was created or occurred and until such director's
successor shall have been elected and qualified.

                           b.      If at the time of filling any vacancy or any
newly created directorship, the directors then in office shall constitute less
than a majority of the whole board (as constituted immediately prior to any
such increase), the Delaware Court of Chancery may, upon application of any
stockholder or stockholders holding at least ten percent (10%) of the total
number of the shares at the time outstanding having the right to vote for such
directors, summarily order an election to be held to fill any such vacancies or
newly created directorships, or to replace the directors chosen by the
directors then in offices as aforesaid, which election shall be governed by
Section 211 of the DGCL.

         B.

                  1.       BYLAW AMENDMENTS.

                           Subject to paragraph (h) of Section 43 of the Bylaws
, the Bylaws may be altered or amended or new Bylaws adopted by the affirmative
vote of at least sixty-six and two-thirds percent (66-2/3%) of the voting power
of all of the then-outstanding shares of the Voting Stock. The Board of
Directors shall also have the power to adopt, amend, or repeal Bylaws.

                  2.       The directors of the Corporation need not be elected
by written ballot unless the Bylaws so provide.

                  3.       No action shall be taken by the stockholders of the
Corporation except at an annual or special meeting of stockholders called in
accordance with the Bylaws and, following the closing of the Initial Public
Offering, no action shall be taken by the stockholders by written consent.

                  4.       Advance notice of stockholder nominations for the
election of directors and of business to be brought by stockholders before any
meeting of the stockholders of the Corporation shall be given in the manner
provided in the Bylaws of the Corporation.

                                      VI.

         A.       The liability of the directors for monetary damages shall be
eliminated to the fullest extent under applicable law.



                                       3.
<PAGE>   5

         B.       Any repeal or modification of this Article VI shall be
prospective and shall not affect the rights under this Article VI in effect at
the time of the alleged occurrence of any act or omission to act giving rise to
liability or indemnification.

                                      VII.

         A.       The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute, except as provided in paragraph
B. of this Article VII, and all rights conferred upon the stockholders herein
are granted subject to this reservation.

         B.       Notwithstanding any other provisions of this Certificate of
Incorporation or any provision of law which might otherwise permit a lesser
vote or no vote, but in addition to any affirmative vote of the holders of any
particular class or series of the Voting Stock required by law, this
Certificate of Incorporation or any Preferred Stock Designation, the
affirmative vote of the holders of at least sixty-six and two-thirds percent
(66-2/3%) of the voting power of all of the then-outstanding shares of the
Voting Stock, voting together as a single class, shall be required to alter,
amend or repeal Articles V, VI and VII.

                            (A DELAWARE CORPORATION)




                                    ARTICLE I

                                     OFFICES

         SECTION 1. REGISTERED OFFICE. The registered office of the corporation
in the State of Delaware shall be in the City of Wilmington, County of New
Castle.

         SECTION 2. OTHER OFFICES. The corporation shall also have and maintain
an office or principal place of business at such place as may be fixed by the
Board of Directors, and may also have offices at such other places, both within
and without the State of Delaware as the Board of Directors may from time to
time determine or the business of the corporation may require.

                                 CORPORATE SEAL

         SECTION 3. CORPORATE SEAL. The corporate seal shall consist of a die

                                   ARTICLE III

                             STOCKHOLDERS' MEETINGS

         SECTION 4. PLACE OF MEETINGS. Meetings of the stockholders of the
corporation shall be held at such place, either within or without the State of
Delaware, as may be 




                                       1
<PAGE>   6

designated from time to time by the Board of Directors, or, if not so
designated, then at the office of the corporation required to be maintained
pursuant to Section 2 hereof.

     SECTION 5. ANNUAL MEETING.

         (a) The annual meeting of the stockholders of the corporation, for the
purpose of election of Directors and for such other business as may lawfully
come before it, shall be held on such date and at such time as may be designated
from time to time by the Board of Directors.

         (b) At an annual meeting of the stockholders, only such business shall
be conducted as shall have been properly brought before the meeting. To be
properly brought before an annual meeting, business must be: (A) specified in
the notice of meeting (or any supplement thereto) given by or at the direction
of the Board of Directors, (B) otherwise properly brought before the meeting by
or at the direction of the Board of Directors, or (C) otherwise properly brought
before the meeting by a stockholder. For business to be properly brought before
an annual meeting by a stockholder, the stockholder must have given timely
notice thereof in writing to the Secretary of the corporation. To be timely, a
stockholder's notice must be delivered to or mailed and received at the
principal executive offices of the corporation not less than one hundred twenty
(120) calendar days in advance of the date of the corporation's proxy statement
released to stockholders in connection with the previous year's annual meeting
of stockholders; provided, however, that in the event that no annual meeting was
held in the previous year or the date of the annual meeting has been changed by
more than thirty (30) days from the date contemplated at the time of the
previous year's proxy statement, notice by the stockholder to be timely must be
so received a reasonable time before the solicitation is made. A stockholder's
notice to the Secretary shall set forth as to each matter the stockholder
proposes to bring before the annual meeting: (i) a brief description of the
business desired to be brought before the annual meeting and the reasons for
conducting such business at the annual meeting, (ii) the name and address, as
they appear on the corporation's books, of the stockholder proposing such
business, (iii) the class and number of shares of the corporation which are
beneficially owned by the stockholder, (iv) any material interest of the
stockholder in such business and (v) any other information that is required to
be provided by the stockholder pursuant to Regulation 14A under the Securities
Exchange Act of 1934, as amended (the "1934 Act"), in his capacity as a
proponent to a stockholder proposal. Notwithstanding the foregoing, in order to
include information with respect to a stockholder proposal in the proxy
statement and form of proxy for a stockholder's meeting, stockholders must
provide notice as required by the regulations promulgated under the 1934 Act.
Notwithstanding anything in these Bylaws to the contrary, no business shall be
conducted at any annual meeting except in 




                                       2
<PAGE>   7

accordance with the procedures set forth in this paragraph (b). The chairman of
the annual meeting shall, if the facts warrant, determine and declare at the
meeting that business was not properly brought before the meeting and in
accordance with the provisions of this paragraph (b), and, if he should so
determine, he shall so declare at the meeting that any such business not
properly brought before the meeting shall not be transacted.

         (c) Only persons who are nominated in accordance with the procedures
set forth in this paragraph (c) shall be eligible for election as Directors.
Nominations of persons for election to the Board of Directors of the corporation
may be made at a meeting of stockholders by or at the direction of the Board of
Directors or by any stockholder of the corporation entitled to vote in the
election of Directors at the meeting who complies with the notice procedures set
forth in this paragraph (c). Such nominations, other than those made by or at
the direction of the Board of Directors, shall be made pursuant to timely notice
in writing to the Secretary of the corporation in accordance with the provisions
of paragraph (b) of this Section 5. Such stockholder's notice shall set forth
(i) as to each person, if any, whom the stockholder proposes to nominate for
election or re-election as a Director: (A) the name, age, business address and
residence address of such person, (B) the principal occupation or employment of
such person, (C) the class and number of shares of the corporation which are
beneficially owned by such person, (D) a description of all arrangements or
understandings between the stockholder and each nominee and any other person or
persons (naming such person or persons) pursuant to which the nominations are to
be made by the stockholder, and (E) any other information relating to such
person that is required to be disclosed in solicitations of proxies for election
of Directors, or is otherwise required, in each case pursuant to Regulation 14A
under the 1934 Act (including without limitation such person's written consent
to being named in the proxy statement, if any, as a nominee and to serving as a
Director if elected); and (ii) as to such stockholder giving notice, the
information required to be provided pursuant to paragraph (b) of this Section 5.
At the request of the Board of Directors, any person nominated by a stockholder
for election as a Director shall furnish to the Secretary of the corporation
that information required to be set forth in the stockholder's notice of
nomination which pertains to the nominee. No person shall be eligible for
election as a Director of the corporation unless nominated in accordance with
the procedures set forth in this paragraph (c). The chairman of the meeting
shall, if the facts warrant, determine and declare at the meeting that a
nomination was not made in accordance with the procedures prescribed by these
Bylaws, and if he should so determine, he shall so declare at the meeting, and
the defective nomination shall be disregarded.

     SECTION 6. SPECIAL MEETINGS.

         (a) Special meetings of the stockholders of the corporation may be
called, for any purpose or purposes, by (i) the Chairman of the Board of
Directors, (ii) the Board of Directors pursuant to a resolution adopted by a
majority of the total number of authorized Directors (whether or not there exist
any vacancies in previously authorized Directorships at the time any such
resolution is presented to the Board of Directors for adoption) or (iii) by the
holders of shares entitled to cast not less than thirty percent (30%) of the
votes at the meeting, and shall be held at such place, on such date, and at such
time as the Board of Directors shall fix; provided, however, that following
registration of any of the classes of equity securities of the corporation
pursuant to the provisions of the 1934 Act, special meetings of the stockholders
may only be called by the Board of Directors pursuant to a resolution adopted by
a majority of the total number of authorized Directors.

         (b) If a special meeting is called by any person or persons other than
the Chairman of the Board of Directors or the Board of Directors, the request
shall be in writing, specifying the general nature of the business proposed to
be transacted, and shall be delivered personally or sent by registered mail or
by telegraphic or other facsimile transmission to the Chairman of the Board of
Directors, the President, any Vice President, or the Secretary of the
corporation. No business may be transacted at such special meeting otherwise
than specified in such notice. The officer receiving the request shall cause
notice to be promptly given to the stockholders entitled to vote, in accordance
with the provisions of Section 7 of these Bylaws, that a meeting will be held
not less than thirty-five (35) nor more than sixty (60) days after the receipt
of the request. If the notice is not given within twenty (20) days after the
receipt of the request, the person or persons requesting the meeting may give
the notice. Nothing contained in this paragraph (b) shall be construed as
limiting, fixing, or affecting the time when a meeting of stockholders called by
action of the Board of Directors may be held.

     SECTION 7. NOTICE OF MEETINGS. Except as otherwise provided by law or the
Certificate of Incorporation, written notice of each meeting of stockholders
shall be given not less than ten (10) nor more than sixty (60) days before the
date of the meeting to each stockholder entitled to vote at such meeting, such
notice to specify the place, date and hour and purpose or purposes of the
meeting. Notice of the time, place and purpose of any meeting of stockholders
may be waived in writing, signed by the person entitled to notice thereof,
either before or after such meeting, and will be waived by any stockholder by
his attendance thereat in person or by proxy, except when the stockholder
attends a meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened. Any 




                                       4
<PAGE>   9

stockholder so waiving notice of such meeting shall be bound by the proceedings
of any such meeting in all respects as if due notice thereof had been given.

     SECTION 8. QUORUM. At all meetings of stockholders, except where otherwise
provided by statute or by the Certificate of Incorporation, or by these Bylaws,
the presence, in person or by proxy duly authorized, of the holders of a
majority of the outstanding shares of stock entitled to vote shall constitute a
quorum for the transaction of business. Any shares, the voting of which at said
meeting is enjoined, or which for any reason cannot be lawfully voted at such
meeting, shall not be counted to determine a quorum at such meeting. In the
absence of a quorum any meeting of stockholders may be adjourned, from time to
time, either by the chairman of the meeting or by vote of the holders of a
majority of the shares represented thereat, but no other business shall be
transacted at such meeting. The stockholders present at a duly called or
convened meeting, at which a quorum is present, may continue to transact
business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum. Except as otherwise provided by law,
the Certificate of Incorporation or these Bylaws, all action taken by the
holders of a majority of the voting power represented at any meeting at which a
quorum is present shall be valid and binding upon the corporation; provided,
however, that Directors shall be elected by a plurality of the votes of the
shares present in person or represented by proxy at the meeting and entitled to
vote on the election of Directors. Where a separate vote by a class or classes
or series is required, except where otherwise provided by the statute or by the
Certificate of Incorporation or these Bylaws, a majority of the outstanding
shares of such class or classes or series, present in person or represented by
proxy, shall constitute a quorum entitled to take action with respect to that
vote on that matter and, except where otherwise provided by the statute or by
the Certificate of Incorporation or these Bylaws, the affirmative vote of the
majority (plurality, in the case of the election of Directors) of the shares of
such class or classes or series present in person or represented by proxy at the
meeting shall be the act of such class or classes or series.

     SECTION 9. ADJOURNMENT AND NOTICE OF ADJOURNED MEETINGS. Any meeting of
stockholders, whether annual or special, may be adjourned from time to time
either by the chairman of the meeting or by the vote of a majority of the shares
represented thereat. When a meeting is adjourned to another time or place,
notice need not be given of the adjourned meeting if the time and place thereof
are announced at the meeting at which the adjournment is taken. At the adjourned
meeting, the corporation may transact any business which might have been
transacted at the original meeting. If the adjournment is for more than thirty
(30) days or if after the adjournment a new record date is fixed for the
adjourned meeting, a notice of the adjourned meeting shall be given to each
stockholder of record entitled to vote at the meeting.




                                       5
<PAGE>   10

     SECTION 10. VOTING RIGHTS. For the purpose of determining those
stockholders entitled to vote at any meeting of the stockholders, except as
otherwise provided by law, only persons in whose names shares stand on the stock
records of the corporation on the record date, as provided in Section 12 of
these Bylaws, shall be entitled to vote at any meeting of stockholders. Every
person entitled to vote or execute consents shall have the right to do so either
in person or by an agent or agents authorized by a written proxy granted in
accordance with Delaware law. An agent so appointed need not be a stockholder.
No proxy shall be voted after three (3) years from its date of creation unless
the proxy provides for a longer period. All elections of Directors shall be by
written ballot, unless otherwise provided in the Certificate of Incorporation.

     SECTION 11. JOINT OWNERS OF STOCK. If shares or other securities having
voting power stand of record in the names of two (2) or more persons, whether
fiduciaries, members of a partnership, joint tenants, tenants in common, tenants
by the entirety, or otherwise, or if two (2) or more persons have the same
fiduciary relationship respecting the same shares, unless the Secretary is given
written notice to the contrary and is furnished with a copy of the instrument or
order appointing them or creating the relationship wherein it is so provided,
their acts with respect to voting shall have the following effect: (a) if only
one (1) votes, his act binds all; (b) if more than one (1) votes, the act of the
majority so voting binds all; (c) if more than one (1) votes, but the vote is
evenly split on any particular matter, each faction may vote the securities in
question proportionally, or may apply to the Delaware Court of Chancery for
relief as provided in the General Corporation Law of Delaware, Section 217(b).
If the instrument filed with the Secretary shows that any such tenancy is held
in unequal interests, a majority or even-split for the purpose of subsection (c)
shall be a majority or even-split in interest.

     SECTION 12. LIST OF STOCKHOLDERS. The Secretary shall prepare and make, at
least ten (10) days before every meeting of stockholders, a complete list of the
stockholders entitled to vote at said meeting, arranged in alphabetical order,
showing the address of each stockholder and the number of shares registered in
the name of each stockholder. Such list shall be open to the examination of any
stockholder, for any purpose germane to the meeting, during ordinary business
hours, for a period of at least ten (10) days prior to the meeting, either at a
place within the city where the meeting is to be held, which place shall be
specified in the notice of the meeting, or, if not specified, at the place where
the meeting is to be held. The list shall be produced and kept at the time and
place of meeting during the whole time thereof and may be inspected by any
stockholder who is present.

<PAGE>   11

     SECTION 13. ACTION WITHOUT MEETING.

         (a) Unless otherwise provided in the Certificate of Incorporation, any
action required by statute to be taken at any annual or special meeting of the
stockholders, or any action which may be taken at any annual or special meeting
of the stockholders, may be taken without a meeting, without prior notice and
without a vote, if a consent in writing, setting forth the action so taken,
shall be signed by the holders of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares entitled to vote thereon were present and
voted.

         (b) Every written consent shall bear the date of signature of each
stockholder who signs the consent, and no written consent shall be effective to
take the corporate action referred to therein unless, within sixty (60) days of
the earliest dated consent delivered to the corporation in the manner herein
required, written consents signed by a sufficient number of stockholders to take
action are delivered to the corporation by delivery to its registered office in
the State of Delaware, its principal place of business or an officer or agent of
the corporation having custody of the book in which proceedings of meetings of
stockholders are recorded. Delivery made to a corporation's registered office
shall be by hand or by certified or registered mail, return receipt requested.

         (c) Prompt notice of the taking of the corporate action without a
meeting by less than unanimous written consent shall be given to those
stockholders who have not consented in writing. If the action which is consented
to is such as would have required the filing of a certificate under any section
of the General Corporation Law of the State of Delaware if such action had been
voted on by stockholders at a meeting thereof, then the certificate filed under
such section shall state, in lieu of any statement required by such section
concerning any vote of stockholders, that written notice and written consent
have been given as provided in Section 228 of the General Corporation Law of
Delaware.

     SECTION 14. ORGANIZATION.

                                    DIRECTORS

     SECTION 15. NUMBER AND TERM OF OFFICE. The Board of Directors shall consist
of one or more members, the number thereof to be determined from time to time by
resolution of the Board of Directors. The number of authorized Directors may be
modified from time to time by amendment of this Section 15 in accordance with
the provisions of Section 45 hereof. Except as provided in Section 18, the
Directors shall be elected by the stockholders at their annual meeting in each
year and shall hold office until the next annual meeting and until their
successors shall be duly elected and qualified. Directors need not be
stockholders unless so required by the Certificate of Incorporation. If for any
cause, the Directors shall not have been elected at an annual meeting, they may
be elected as soon thereafter as convenient at a special meeting of the
stockholders called for that purpose in the manner provided in these Bylaws. No
reduction of the authorized number of Directors shall have the effect of
removing any Director before the Director's term of office expires, unless such
removal is made pursuant to the provisions of Section 20 hereof.

     SECTION 16. POWERS. The powers of the corporation shall be exercised, its
business conducted and its property controlled by the Board of Directors, except
as may be otherwise provided by statute or by the Certificate of Incorporation.

     SECTION 17. CLASSES OF DIRECTORS. Subject to the rights of the holders of
any series of Preferred Stock to elect additional directors under specified
circumstances, the directors shall be divided into three classes designated as
Class I, Class II and Class III, respectively. Directors shall be assigned to
each class in accordance with a resolution or resolutions adopted by the Board
of Directors. At the first annual meeting of stockholders following the adoption
of these Bylaws, the term of office of the Class I directors shall expire and
Class I directors shall be elected for a full term of three years. At the second
annual meeting of stockholders following the adoption of these Bylaws, the term
of office of the Class I directors shall expire and Class II directors shall be
elected for a full term of three years. At the third annual meeting of
stockholders following the adoption of these Bylaws, the term of office of the
Class III directors shall expire and Class III directors shall be elected for a
full term of three years. At each succeeding annual meeting of stockholders,
directors shall be elected for a full term of three years to succeed the
directors of the class whose terms expire at such annual meeting.

     Notwithstanding the foregoing provisions of this section, each director
shall serve until his successor is duly elected and qualified or until his
death, resignation or removal. No decrease in the number of directors
constituting the Board of Directors shall shorten the term of any incumbent
director.

     SECTION 18. VACANCIES. Unless otherwise provided in the Certificate of
Incorporation, any vacancies occurring on the Board of Directors and any newly
created Directorships resulting from any increase in the authorized number of
Directors, shall be filled only by the affirmative vote of a majority of the
stockholders entitled to vote thereon. Any Director elected in accordance with
the preceding sentence shall hold office for the remainder of the full term of
the Director for which the vacancy was created or occurred and until such
Director's successor shall have been elected and qualified. A vacancy in the
Board of Directors shall be deemed to exist under this Bylaw in the case of the
death, removal or resignation of any Director, or if the stockholders fail at
any meeting of stockholders at which Directors are to be elected (including any
meeting referred to in Section 20 below) to elect the number of Directors then
constituting the whole Board of Directors.

     SECTION 19. RESIGNATION. Any Director may resign at any time by delivering
his written resignation to either the Board of Directors or the Secretary, such
resignation to specify whether it will be effective at a particular time, upon
receipt by the Board of Directors or the Secretary or at the pleasure of the
Board of Directors. If no such specification is made, it shall be deemed
effective at the pleasure of the Board of Directors. Unless otherwise provided
in the Certificate of Incorporation, when one or more Directors shall resign
from the Board of Directors, effective at a future date, a 




                                       9
<PAGE>   14

majority of the Directors then in office, including those who have so resigned,
shall have power to fill such vacancy or vacancies, the vote thereon to take
effect when such resignation or resignations shall become effective, and each
Director so chosen shall hold office for the unexpired portion of the term of
the Director whose place shall be vacated and until his successor shall have
been duly elected and qualified.

     SECTION 20. REMOVAL. At a special meeting of stockholders called for the
purpose in the manner hereinabove provided, subject to any limitations imposed
by law, the Certificate of Incorporation or any agreement by and among the
Corporation and its investors, the Board of Directors, or any individual
Director, may be removed from office, with or without cause, and a new Director
or Directors elected by a vote of stockholders holding a majority of the
outstanding shares entitled to vote at an election of Directors.

resignation from the committee or from the Board of Directors. The Board of
Directors may at any time for any reason remove any individual committee member
and the Board of Directors may fill any committee vacancy created by death,

determined by the Board of Directors, or by any such committee, and when notice
thereof has been given to each member of such committee, no further notice of

committee, upon written notice to the members of such committee of the time and
place of such special meeting given in the manner provided for the giving of
written notice to members of the Board of Directors of the time and place of
special meetings of the Board of Directors. Notice of any special meeting of any
committee may be waived in writing at any time before or after the meeting and
will be waived by any Director by attendance thereat, except when the Director
attends such special meeting for the express purpose of objecting, at the
beginning of the meeting, to the transaction of any business because the meeting
is not lawfully called or convened. A majority of the authorized number of

precedent to the issuance of a new certificate or certificates, the owner of
such lost, stolen, or destroyed certificate or certificates, or his legal
representative, to advertise the same in such manner as it shall require or to
give the corporation a surety bond in such form and amount as it may direct as
indemnity against any claim that may be made against the corporation with

preceding the day on which notice is given, or if notice is waived, at the close
of business on the day next preceding the day on which the meeting is held. A

meeting of stockholders shall apply to any adjournment of the meeting; provided,
however, that the Board of Directors may fix a new record date for the adjourned
meeting.

         (b) In order that the corporation may determine the stockholders
entitled to consent to corporate action in writing without a meeting, the Board
of Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board of
Directors, and which date shall not be more than ten (10) days after the date
upon which the resolution fixing the record date is adopted by the Board of
Directors. Any stockholder of record seeking to have the stockholders authorize
or take corporate action by written consent shall, by written notice to the
Secretary, request the Board of Directors to fix a record date. The Board of
Directors shall promptly, but in all events within ten (10) days after the date
on which such a request is received, adopt a resolution fixing the record date.
If no record date has been fixed by the Board of Directors within ten (10) days
of the date on which such a request is received, the record date for determining
stockholders entitled to consent to corporate action in writing without a
meeting, when no prior action by the Board of Directors is required by
applicable law, shall be the first date on which a signed written consent
setting forth the action taken or proposed to be taken is delivered to the
corporation by delivery to its registered office in the State of Delaware, its
principal place of business or an officer or agent of the corporation having
custody of the book in which proceedings of meetings of stockholders are
recorded. Delivery made to the corporation's registered office shall be by hand
or by certified or registered mail, return receipt requested. If no record date
has been fixed by the Board of Directors and prior action by the Board of
Directors is required by law, the record date for determining stockholders
entitled to consent to corporate action in writing without a meeting shall be at
the close of business on the day on which the Board of Directors adopts the
resolution taking such prior action.

         (c) In order that the corporation may determine the stockholders
entitled to receive payment of any dividend or other distribution or allotment
of any rights or the stockholders entitled to exercise any rights in respect of
any change, conversion or exchange of stock, or for the purpose of any other
lawful action, the Board of Directors may fix, in advance, a record date, which
record date shall not precede the date upon which the resolution fixing the
record date is adopted, and which record date shall be not more than sixty (60)
days prior to such action. If no record date is fixed, the record date 




                                       19
<PAGE>   24

for determining stockholders for any such purpose shall be at the close of
business on the day on which the Board of Directors adopts the resolution
relating thereto.

     SECTION 38. REGISTERED STOCKHOLDERS. The corporation shall be entitled to
recognize the exclusive right of a person registered on its books as the owner
of shares to receive dividends, and to vote as such owner, and shall not be
bound to recognize any equitable or other claim to or interest in such share or
shares on the part of any other person whether or not it shall have express or
other notice thereof, except as otherwise provided by the laws of Delaware.

                                  ARTICLE VIII

                       OTHER SECURITIES OF THE CORPORATION

     SECTION 39. EXECUTION OF OTHER SECURITIES. All bonds, debentures and other
corporate securities of the corporation, other than stock certificates (covered
in Section 34), may be signed by the Chairman of the Board of Directors, the
President or any Vice President, or such other person as may be authorized by
the Board of Directors, and the corporate seal impressed thereon or a facsimile
of such seal imprinted thereon and attested by the signature of the Secretary or
an Assistant Secretary, or the Chief Financial Officer or Treasurer or an
Assistant Treasurer; provided, however, that where any such bond, debenture or
other corporate security shall be authenticated by the manual signature of a
trustee under an indenture pursuant to which such bond, debenture or other
corporate security shall be issued, the signatures of the persons signing and
attesting the corporate seal on such bond, debenture or other corporate security
may be the imprinted facsimile of the signatures of such persons. Interest
coupons appertaining to any such bond, debenture or other corporate security,
authenticated by a trustee as aforesaid, shall be signed by the Treasurer or an
Assistant Treasurer of the corporation or such other person as may be authorized
by the Board of Directors, or bear imprinted thereon the facsimile signature of
such person. In case any officer who shall have signed or attested any bond,
debenture or other corporate security, or whose facsimile signature shall appear
thereon or on any such interest coupon, shall have ceased to be such officer
before the bond, debenture or other corporate security so signed or attested
shall have been delivered, such bond, debenture or other corporate security
nevertheless may be adopted by the corporation and issued and delivered as
though the person who signed the same or whose facsimile signature shall have
been used thereon had not ceased to be such officer of the corporation.

                                    DIVIDENDS

     SECTION 40. DECLARATION OF DIVIDENDS. Dividends upon the capital stock of
the corporation, subject to the provisions of the Certificate of Incorporation,
if any, may be declared by the Board of Directors pursuant to law at any regular
or special meeting. Dividends may be paid in cash, in property, or in shares of
the capital stock, subject to the provisions of the Certificate of
Incorporation.

     SECTION 41. DIVIDEND RESERVE. Before payment of any dividend, there may be
set aside out of any funds of the corporation available for dividends such sum
or sums as the Board of Directors from time to time, in their absolute
discretion, think proper as a reserve or reserves to meet contingencies, or for
equalizing dividends, or for repairing or maintaining any property of the
corporation, or for such other purpose as the Board of Directors shall think
conducive to the interests of the corporation, and the Board of Directors may
modify or abolish any such reserve in the manner in which it was created.

                                    ARTICLE X

                                   FISCAL YEAR

     SECTION 42. FISCAL YEAR. The fiscal year of the corporation shall be fixed
by resolution of the Board of Directors.

                                   ARTICLE XI

                                 INDEMNIFICATION

     SECTION 43. INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES AND OTHER
AGENTS.

         (a) DIRECTORS. The corporation shall indemnify its Directors to the
fullest extent not prohibited by the Delaware General Corporation Law; provided,
however, that the corporation shall not be required to indemnify any Director in
connection with any proceeding (or part thereof) initiated by such person or any
proceeding by such person against the corporation or its Directors, officers,
employees or other agents unless (i) such indemnification is expressly required
to be made by law, (ii) the proceeding was authorized by the Board of Directors
of the corporation, (iii) such indemnification is provided by the corporation,
in its sole discretion, pursuant to the powers vested in the corporation under
the Delaware General Corporation Law.



                                       21
<PAGE>   26

         (b) OFFICERS, EMPLOYEES AND OTHER AGENTS. The corporation shall have
power to indemnify its officers, employees and other agents as set forth in the
Delaware General Corporation Law.

         (c) EXPENSES. The corporation shall advance to any person who was or is
a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that he is or was a Director or executive
officer, of the corporation, or is or was serving at the request of the
corporation as a Director or executive officer of another corporation,
partnership, joint venture, trust or other enterprise, prior to the final
disposition of the proceeding, promptly following request therefor, all expenses
incurred by any Director or executive officer in connection with such proceeding
upon receipt of an undertaking by or on behalf of such person to repay said
amounts if it should be determined ultimately that such person is not entitled
to be indemnified under this Bylaw or otherwise.

         (d) ENFORCEMENT. Without the necessity of entering into an express
contract, all rights to indemnification and advances to Directors and executive
officers under this Bylaw shall be deemed to be contractual rights and be
effective to the same extent and as if provided for in a contract between the
corporation and the Director or executive officer. Any right to indemnification
or advances granted by this Bylaw to a Director or executive officer shall be
enforceable by or on behalf of the person holding such right in any court of
competent jurisdiction if (i) the claim for indemnification or advances is
denied, in whole or in part, or (ii) no disposition of such claim is made within
ninety (90) days of request therefor. The claimant in such enforcement action,
if successful in whole or in part, shall be entitled to be paid also the expense
of prosecuting his claim. In connection with any claim for indemnification, the
corporation shall be entitled to raise as a defense to any such action that the
claimant has not met the standards of conduct that make it permissible under the
Delaware General Corporation Law for the corporation to indemnify the claimant
for the amount claimed. Neither the failure of the corporation (including its
Board of Directors, independent legal counsel or its stockholders) to have made
a determination prior to the commencement of such action that indemnification of
the claimant is proper in the circumstances because he has met the applicable
standard of conduct set forth in the Delaware General Corporation Law, nor an
actual determination by the corporation (including its Board of Directors,
independent legal counsel or its stockholders) that the claimant has not met
such applicable standard of conduct, shall be a defense to the action or create
a presumption that claimant has not met the applicable standard of conduct.



                                       22
<PAGE>   27

         (e) NON-EXCLUSIVITY OF RIGHTS. The rights conferred on any person by
this Bylaw shall not be exclusive of any other right which such person may have
or hereafter acquire under any statute, provision of the Certificate of
Incorporation, Bylaws, agreement, vote of stockholders or disinterested
Directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding office. The corporation is specifically
authorized to enter into individual contracts with any or all of its Directors,
officers, employees or agents respecting indemnification and advances, to the
fullest extent not prohibited by the Delaware General Corporation Law.

         (f) SURVIVAL OF RIGHTS. The rights conferred on any person by this
Bylaw shall continue as to a person who has ceased to be a Director, officer,
employee or other agent and shall inure to the benefit of the heirs, executors
and administrators of such a person.

         (g) INSURANCE. To the fullest extent permitted by the Delaware General
Corporation Law, the corporation, upon approval by the Board of Directors, may
purchase insurance on behalf of any person required or permitted to be
indemnified pursuant to this Bylaw.

         (h) AMENDMENTS. Any repeal or modification of this Bylaw shall only be
prospective and shall not affect the rights under this Bylaw in effect at the
time of the alleged occurrence of any action or omission to act that is the
cause of any proceeding against any agent of the corporation.

         (i) SAVING CLAUSE. If this Bylaw or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
corporation shall nevertheless indemnify each Director and executive officer to
the full extent not prohibited by any applicable portion of this Bylaw that
shall not have been invalidated, or by any other applicable law.

         (j) CERTAIN DEFINITIONS. For the purposes of this Bylaw, the following
definitions shall apply:

             (i) The term "proceeding" shall be broadly construed and shall
include, without limitation, the investigation, preparation, prosecution,
defense, settlement, arbitration and appeal of, and the giving of testimony in,
any threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative.

             (ii) The term "expenses" shall be broadly construed and shall
include, without limitation, court costs, attorneys' fees, witness fees, fines,
amounts paid 



                                       23
<PAGE>   28

in settlement or judgment and any other costs and expenses of any nature or kind
incurred in connection with any proceeding.

             (iii) The term the "corporation" shall include, in addition to the
resulting corporation, any constituent corporation (including any constituent of
a constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
Directors, officers, and employees or agents, so that any person who is or was a
Director, officer, employee or agent of such constituent corporation, or is or
was serving at the request of such constituent corporation as a Director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall stand in the same position under the provisions
of this Bylaw with respect to the resulting or surviving corporation as he would
have with respect to such constituent corporation if its separate existence had
continued.

             (iv) References to a "Director," "executive officer," "officer,"
"employee," or "agent" of the corporation shall include, without limitation,
situations where such person is serving at the request of the corporation as,
respectively, a Director, executive officer, officer, employee, trustee or agent
of another corporation, partnership, joint venture, trust or other enterprise.

             (v) References to "other enterprises" shall include employee
benefit plans; references to "fines" shall include any excise taxes assessed on
a person with respect to an employee benefit plan; and references to "serving at
the request of the corporation" shall include any service as a Director,
officer, employee or agent of the corporation which imposes duties on, or
involves services by, such Director, officer, employee, or agent with respect to
an employee benefit plan, its participants, or beneficiaries; and a person who
acted in good faith and in a manner he reasonably believed to be in the interest
of the participants and beneficiaries of an employee benefit plan shall be
deemed to have acted in a manner "not opposed to the best interests of the
corporation" as referred to in this Bylaw.

                                   ARTICLE XII

                                     NOTICES

     SECTION 44. NOTICES.

         (a) NOTICE TO STOCKHOLDERS. Whenever, under any provisions of these
Bylaws, notice is required to be given to any stockholder, it shall be given in
writing, 




                                       24
<PAGE>   29

timely and duly deposited in the United States mail, postage prepaid,
and addressed to his last known post office address as shown by the stock record
of the corporation or its transfer agent.

         (b) NOTICE TO DIRECTORS. Any notice required to be given to any
Director may be given by the method stated in subsection (a), or by facsimile,
telex or telegram, except that such notice other than one which is delivered
personally shall be sent to such address as such Director shall have filed in
writing with the Secretary, or, in the absence of such filing, to the last known
post office address of such Director.

         (c) AFFIDAVIT OF MAILING. An affidavit of mailing, executed by a duly
authorized and competent employee of the corporation or its transfer agent
appointed with respect to the class of stock affected, specifying the name and
address or the names and addresses of the stockholder or stockholders, or
Director or Directors, to whom any such notice or notices was or were given, and
the time and method of giving the same, shall in the absence of fraud, be prima
facie evidence of the facts therein contained.

         (d) TIME NOTICES DEEMED GIVEN. All notices given by mail, as above
provided, shall be deemed to have been given as at the time of mailing, and all
notices given by facsimile, telex or telegram shall be deemed to have been given
as of the sending time recorded at time of transmission.

         (e) METHODS OF NOTICE. It shall not be necessary that the same method
of giving notice be employed in respect of all Directors, but one permissible
method may be employed in respect of any one or more, and any other permissible
method or methods may be employed in respect of any other or others.

         (f) FAILURE TO RECEIVE NOTICE. The period or limitation of time within
which any stockholder may exercise any option or right, or enjoy any privilege
or benefit, or be required to act, or within which any Director may exercise any
power or right, or enjoy any privilege, pursuant to any notice sent him in the
manner above provided, shall not be affected or extended in any manner by the
failure of such stockholder or such Director to receive such notice.

         (g) NOTICE TO PERSON WITH WHOM COMMUNICATION IS UNLAWFUL. Whenever
notice is required to be given, under any provision of law or of the Certificate
of Incorporation or Bylaws of the corporation, to any person with whom
communication is unlawful, the giving of such notice to such person shall not be
required and there shall be no duty to apply to any governmental authority or
agency for a license or permit to give such notice to such person. Any action or
meeting which shall be taken or held 




                                       25
<PAGE>   30
without notice to any such person with whom communication is unlawful shall
have the same force and effect as if such notice had been duly given. In the
event that the action taken by the corporation is such as to require the filing
of a certificate under any provision of the Delaware General Corporation Law,
the certificate shall state, if such is the fact and if notice is required, that
notice was given to all persons entitled to receive notice except such persons
with whom communication is unlawful.

         (h) NOTICE TO PERSON WITH UNDELIVERABLE ADDRESS. Whenever notice is
required to be given, under any provision of law or the Certificate of
Incorporation or Bylaws of the corporation, to any stockholder to whom (i)
notice of two consecutive annual meetings, and all notices of meetings or of the
taking of action by written consent without a meeting to such person during the
period between such two consecutive annual meetings, or (ii) all, and at least
two, payments (if sent by first class mail) of dividends or interest on
securities during a twelve-month period, have been mailed addressed to such
person at his address as shown on the records of the corporation and have been
returned undeliverable, the giving of such notice to such person shall not be
required. Any action or meeting which shall be taken or held without notice to
such person shall have the same force and effect as if such notice had been duly
given. If any such person shall deliver to the corporation a written notice
setting forth his then current address, the requirement that notice be given to
such person shall be reinstated. In the event that the action taken by the
corporation is such as to require the filing of a certificate under any
provision of the Delaware General Corporation Law, the certificate need not
state that notice was not given to persons to whom notice was not required to be
given pursuant to this paragraph.

                                  ARTICLE XIII

                                   AMENDMENTS

     SECTION 45. AMENDMENTS.

         Subject to paragraph (i) of Section 43 of these Bylaws, these Bylaws
may be altered or amended or repealed and new Bylaws adopted by the stockholders
entitled to vote. The Board of Directors shall also have the power to adopt,
amend, or repeal Bylaws.

                                LOANS TO OFFICERS

         SECTION 46. LOANS TO OFFICERS. The corporation may lend money to, or
guarantee any obligation of, or otherwise assist any officer or other employee
of the corporation or of its subsidiaries, including any officer or employee who
is a Director of the corporation or its subsidiaries, whenever, in the judgment
of the Board of Directors, such loan, guarantee or assistance may reasonably be
expected to benefit the corporation. The loan, guarantee or other assistance may
be with or without interest and may be unsecured, or secured in such manner as
the Board of Directors shall approve, including, without limitation, a pledge of
shares of stock of the corporation. Nothing in these Bylaws shall be deemed to
deny, limit or restrict the powers of guaranty or warranty of the corporation at
common law or under any statute.

                             STOCKHOLDERS' MEETINGS

<PAGE>   6

of business to be considered by the stockholders may be made at an annual
meeting of stockholders: (i) pursuant to the corporation's notice of meeting of
stockholders; (ii) by or at the direction of the Board of Directors; or (iii)
by any stockholder of the corporation who was a stockholder of record at the
time of giving of notice provided for in the following paragraph, who is
entitled to vote at the meeting and who complied with the notice procedures set
forth in Section 5.

         (b) At an annual meeting of the stockholders, only such business shall
be conducted as shall have been properly brought before the meeting. For
nominations or other business to be properly brought before an annual meeting
by a stockholder pursuant to clause (iii) of Section 5(a) of these Bylaws, (i)
the stockholder must have given timely notice thereof in writing to the
Secretary of the corporation, (ii) such other business must be a proper matter
for stockholder action under the General Corporation Law of Delaware, (iii) if
the stockholder, or the beneficial owner on whose behalf any such proposal or
nomination is made, has provided the corporation with a Solicitation Notice (as
defined in this Section 5(b)), such stockholder or beneficial owner must, in
the case of a proposal, have delivered a proxy statement and form of proxy to
holders of at least the percentage of the corporation's voting shares required
under applicable law to carry any such proposal, or, in the case of a
nomination or nominations, have delivered a proxy statement and form of proxy
to holders of a percentage of the corporation's voting shares reasonably
believed by such stockholder or beneficial owner to be sufficient to elect the
nominee or nominees proposed to be nominated by such stockholder, and must, in
either case, have included in such materials the Solicitation Notice, and (iv)
if no Solicitation Notice relating thereto has been timely provided pursuant to
this section, the stockholder or beneficial owner proposing such business or
nomination must not have solicited a number of proxies sufficient to have
required the delivery of such a Solicitation Notice under this Section 5. To be
timely, a stockholder's notice shall be delivered to the Secretary at the
principal executive offices of the corporation not later than the close of
business on the ninetieth (90th) day nor earlier than the close of business on
the one hundred twentieth (120th) day prior to the first anniversary of the
preceding year's annual meeting; provided, however, that in the event that the
date of the annual meeting is advanced more than thirty (30) days prior to or
delayed by more than thirty (30) days after the anniversary of the preceding
year's annual meeting, notice by the stockholder to be timely must be so
delivered not earlier than the close of business on the one hundred twentieth
(120th) day prior to such annual meeting and not later than the close of
business on the later of the ninetieth (90th) day prior to such annual meeting
or the tenth (10th) day following the day on which public announcement of the
date of such meeting is first made. In no event shall the public announcement
of an adjournment of an annual meeting commence a new time period for the
giving of a stockholder's notice as described above. Such stockholder's notice
shall set forth: (A) as to each person whom the stockholder proposed to
nominate for election or reelection as a director all information relating to
such person that is required to be disclosed in solicitations of proxies for
election of directors in an election contest, or is otherwise required, in each
case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as
amended (the "1934 Act") and Rule 14a-11 thereunder (including such person's
written consent to being named in the proxy statement as a nominee and to
serving as a director if elected); (B) as to any other business that the
stockholder proposes to bring before the meeting, a brief description of the
business



                                       2.
<PAGE>   7

desired to be brought before the meeting, the reasons for conducting such
business at the meeting and any material interest in such business of such
stockholder and the beneficial owner, if any, on whose behalf the proposal is
made; and (C) as to the stockholder giving the notice and the beneficial owner,
if any, on whose behalf the nomination or proposal is made (i) the name and
address of such stockholder, as they appear on the corporation's books, and of
such beneficial owner, (ii) the class and number of shares of the corporation
which are owned beneficially and of record by such stockholder and such
beneficial owner, and (iii) whether either such stockholder or beneficial owner
intends to deliver a proxy statement and form of proxy to holders of, in the
case of the proposal, at least the percentage of the corporation's voting
shares required under applicable law to carry the proposal or, in the case of a
nomination or nominations, a sufficient number of holders of the corporation's
voting shares to elect such nominee or nominees (an affirmative statement of
such intent, a "Solicitation Notice").

         (c) Notwithstanding anything in the second sentence of Section 5(b) of
these Bylaws to the contrary, in the event that the number of directors to be
elected to the Board of Directors of the Corporation is increased and there is
no public announcement naming all of the nominees for director or specifying
the size of the increased Board of Directors made by the corporation at least
one hundred (100) days prior to the first anniversary of the preceding year's
annual meeting, a stockholder's notice required by this Section 5 shall also be
considered timely, but only with respect to nominees for any new positions
created by such increase, if it shall be delivered to the Secretary at the
principal executive offices of the corporation not later than the close of
business on the tenth (10th) day following the day on which such public
announcement is first made by the corporation.

         (d) Only such persons who are nominated in accordance with the
procedures set forth in this Section 5 shall be eligible to serve as directors
and only such business shall be conducted at a meeting of stockholders as shall
have been brought before the meeting in accordance with the procedures set
forth in this Section 5. Except as otherwise provided by law, the Chairman of
the meeting shall have the power and duty to determine whether a nomination or
any business proposed to be brought before the meeting was made, or proposed,
as the case may be, in accordance with the procedures set forth in these Bylaws
and, if any proposed nomination or business is not in compliance with these
Bylaws, to declare that such defective proposal or nomination shall not be
presented for stockholder action at the meeting and shall be disregarded.

         (e) Notwithstanding the foregoing provisions of this Section 5, in
order to include information with respect to a stockholder proposal in the
proxy statement and form of proxy for a stockholder's meeting, stockholders
must provide notice as required by the regulations promulgated under the 1934
Act. Nothing in these Bylaws shall be deemed to affect any rights of
stockholders to request inclusion of proposals in the corporation proxy
statement pursuant to Rule 14a-8 under the 1934 Act.

         (f) For purposes of this Section 5, "public announcement" shall mean
disclosure in a press release reported by the Dow Jones News Service,
Associated Press or comparable national news service or in a document publicly
filed by the corporation with the Securities and Exchange Commission pursuant
to Section 13, 14 or 15(d) of the 1934 Act.

     SECTION 6. SPECIAL MEETINGS.

         (a) Special meetings of the stockholders of the corporation may be
called, for any purpose or purposes, by (i) the Chairman of the Board of
Directors, (ii) the Chief Executive Officer, (iii) the Board of Directors
pursuant to a resolution adopted by a majority of the total number of
authorized directors (whether or not there exist any vacancies in previously
authorized directorships at the time any such resolution is presented to the
Board of Directors for adoption), and shall be held at such place, on such
date, and at such time as the Board of Directors, shall fix.

         (b) If a special meeting is properly called by any person or persons
other than the Board of Directors, the request shall be in writing, specifying
the general nature of the business proposed to be transacted, and shall be
delivered personally or sent by registered mail or by telegraphic or other
facsimile transmission to the Chairman of the Board of Directors, the Chief
Executive Officer, or the Secretary of the corporation. No business may be
transacted at such special meeting otherwise than specified in such notice. The
Board of Directors shall determine the time and place of such special meeting,
which shall be held not less than thirty-five (35) nor more than one hundred
twenty (120) days after the date of the receipt of the request. Upon
determination of the time and place of the meeting, the officer receiving the
request shall cause notice to be given to the stockholders entitled to vote, in
accordance with the provisions of Section 7 of these Bylaws. If the notice is
not given within one hundred (100) days after the receipt of the request, the
person or persons properly requesting the meeting may set the time and place of
the meeting and give the notice. Nothing contained in this paragraph (b) shall
be construed as limiting, fixing, or affecting the time when a meeting of
stockholders called by action of the Board of Directors may be held.

         (c) Nominations of persons for election to the Board of Directors may
be made at a special meeting of stockholders at which directors are to be
elected pursuant to the corporation's notice of meeting (i) by or at the
direction of the Board of Directors or (ii) by any stockholder of the
corporation who is a stockholder of record at the time of giving notice
provided for in these Bylaws who shall be entitled to vote at the meeting and
who complies with the notice procedures set forth in this Section 6(c). In the
event the corporation calls a special meeting of stockholders for the purpose
of electing one or more directors to the Board of Directors, any such
stockholder may nominate a person or persons (as the case may be), for election
to such position(s) as specified in the corporation's notice of meeting, if the
stockholder's notice required by Section 5(b) of these Bylaws shall be
delivered to the Secretary at the principal executive offices of the
corporation not earlier than the close of business on the one hundred twentieth
(120th) day prior to such special meeting and not later than the close of
business on the later of the ninetieth (90th) day prior to such meeting or the
tenth (10th) day following the day on which public announcement is first made
of the date of the special meeting and of the nominees proposed by the Board of
Directors to be elected at such meeting. In no event shall the public
announcement of an adjournment of a special meeting commence a new time period
for the giving of a stockholder's notice as described above.


                                       4.
<PAGE>   9

     SECTION 7. NOTICE OF MEETINGS. Except as otherwise provided by law or the
Certificate of Incorporation, written notice of each meeting of stockholders
shall be given not less than ten (10) nor more than sixty (60) days before the
date of the meeting to each stockholder entitled to vote at such meeting, such
notice to specify the place, date and hour and purpose or purposes of the
meeting. Notice of the time, place and purpose of any meeting of stockholders
may be waived in writing, signed by the person entitled to notice thereof,
either before or after such meeting, and will be waived by any stockholder by
his attendance thereat in person or by proxy, except when the stockholder
attends a meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened. Any stockholder so waiving notice of such meeting shall be
bound by the proceedings of any such meeting in all respects as if due notice
thereof had been given.

     SECTION 8. QUORUM. At all meetings of stockholders, except where otherwise
provided by statute or by the Certificate of Incorporation, or by these Bylaws,
the presence, in person or by proxy duly authorized, of the holders of a
majority of the outstanding shares of stock entitled to vote shall constitute a
quorum for the transaction of business. In the absence of a quorum, any meeting
of stockholders may be adjourned, from time to time, either by the chairman of
the meeting or by vote of the holders of a majority of the shares represented
thereat, but no other business shall be transacted at such meeting. The
stockholders present at a duly called or convened meeting, at which a quorum is
present, may continue to transact business until adjournment, notwithstanding
the withdrawal of enough stockholders to leave less than a quorum. Except as
otherwise provided by statute, the Certificate of Incorporation or these
Bylaws, in all matters other than the election of directors, the affirmative
vote of the majority of shares present in person or represented by proxy at the
meeting and entitled to vote on the subject matter shall be the act of the
stockholders. Except as otherwise provided by statute, the Certificate of
Incorporation or these Bylaws, directors shall be elected by a plurality of the
votes of the shares present in person or represented by proxy at the meeting
and entitled to vote on the election of directors. Where a separate vote by a
class or classes or series is required, except where otherwise provided by the
statute or by the Certificate of Incorporation or these Bylaws, a majority of
the outstanding shares of such class or classes or series, present in person or
represented by proxy, shall constitute a quorum entitled to take action with
respect to that vote on that matter and, except where otherwise provided by the
statute or by the Certificate of Incorporation or these Bylaws, the affirmative
vote of the majority (plurality, in the case of the election of directors) of
the votes cast by the holders of shares of such class or classes or series
shall be the act of such class or classes or series.

     SECTION 9. ADJOURNMENT AND NOTICE OF ADJOURNED MEETINGS. Any meeting of
stockholders, whether annual or special, may be adjourned from time to time
either by the chairman of the meeting or by the vote of a majority of the
shares casting votes. When a meeting is adjourned to another time or place,
notice need not be given of the adjourned meeting if the time and place thereof
are announced at the meeting at which the adjournment is taken. At the
adjourned meeting, the corporation may transact any business which might have
been transacted at the original meeting. If the adjournment is for more than
thirty (30) days or if after the 




                                       5.
<PAGE>   10

adjournment a new record date is fixed for the adjourned meeting, a notice of
the adjourned meeting shall be given to each stockholder of record entitled to
vote at the meeting.

     SECTION 10. VOTING RIGHTS. For the purpose of determining those
stockholders entitled to vote at any meeting of the stockholders, except as
otherwise provided by law, only persons in whose names shares stand on the
stock records of the corporation on the record date, as provided in Section 12
of these Bylaws, shall be entitled to vote at any meeting of stockholders.
Every person entitled to vote shall have the right to do so either in person or
by an agent or agents authorized by a proxy granted in accordance with Delaware
law. An agent so appointed need not be a stockholder. No proxy shall be voted
after three (3) years from its date of creation unless the proxy provides for a
longer period.

     SECTION 11. JOINT OWNERS OF STOCK. If shares or other securities having
voting power stand of record in the names of two (2) or more persons, whether
fiduciaries, members of a partnership, joint tenants, tenants in common,
tenants by the entirety, or otherwise, or if two (2) or more persons have the
same fiduciary relationship respecting the same shares, unless the Secretary is
given written notice to the contrary and is furnished with a copy of the
instrument or order appointing them or creating the relationship wherein it is
so provided, their acts with respect to voting shall have the following effect:
(a) if only one (1) votes, his act binds all; (b) if more than one (1) votes,
the act of the majority so voting binds all; (c) if more than one (1) votes,
but the vote is evenly split on any particular matter, each faction may vote
the securities in question proportionally, or may apply to the Delaware Court
of Chancery for relief as provided in the Delaware General Corporation Law,
Section 217(b). If the instrument filed with the Secretary shows that any such
tenancy is held in unequal interests, a majority or even-split for the purpose
of subsection (c) shall be a majority or even-split in interest.

     SECTION 12. LIST OF STOCKHOLDERS. The Secretary shall prepare and make, at
least ten (10) days before every meeting of stockholders, a complete list of
the stockholders entitled to vote at said meeting, arranged in alphabetical
order, showing the address of each stockholder and the number of shares
registered in the name of each stockholder. Such list shall be open to the
examination of any stockholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of at least ten (10) days prior to the
meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not
specified, at the place where the meeting is to be held. The list shall be
produced and kept at the time and place of meeting during the whole time
thereof and may be inspected by any stockholder who is present.

     SECTION 13. ACTION WITHOUT MEETING.

         (a) Unless otherwise provided in the Certificate of Incorporation, any
action required by statute to be taken at any annual or special meeting of the
stockholders, or any action which may be taken at any annual or special meeting
of the stockholders, may be taken without a meeting, without prior notice and
without a vote, if a consent in writing, setting forth the action so taken,
shall be signed by the holders of outstanding stock having not less than the
minimum 



                                       6.
<PAGE>   11

number of votes that would be necessary to authorize or take such action at a
meeting at which all shares entitled to vote thereon were present and voted.

         (b) Every written consent shall bear the date of signature of each
stockholder who signs the consent, and no written consent shall be effective to
take the corporate action referred to therein unless, within sixty (60) days of
the earliest dated consent delivered to the corporation in the manner herein
required, written consents signed by a sufficient number of stockholders to
take action are delivered to the corporation by delivery to its registered
office in the State of Delaware, its principal place of business or an officer
or agent of the corporation having custody of the book in which proceedings of
meetings of stockholders are recorded. Delivery made to a corporation's
registered office shall be by hand or by certified or registered mail, return
receipt requested.

         (c) Prompt notice of the taking of the corporate action without a
meeting by less than unanimous written consent shall be given to those
stockholders who have not consented in writing. If the action which is
consented to is such as would have required the filing of a certificate under
any section of the Delaware General Corporation Law if such action had been
voted on by stockholders at a meeting thereof, then the certificate filed under
such section shall state, in lieu of any statement required by such section
concerning any vote of stockholders, that written consent has been given in
accordance with Section 228 of the Delaware General Corporation Law.

         (d) Notwithstanding the foregoing, no such action by written consent
may be taken following the closing of the initial public offering pursuant to
an effective registration statement under the Securities Act of 1933, as
amended (the "1933 Act"), covering the offer and sale of Common Stock of the
corporation (the "Initial Public Offering").

     SECTION 14. ORGANIZATION.

         (a) At every meeting of stockholders, the Chairman of the Board of
Directors, or, if a Chairman has not been appointed or is absent, the
President, or, if the President is absent, a chairman of the meeting chosen by
a majority in interest of the stockholders entitled to vote, present in person
or by proxy, shall act as chairman. The Secretary, or, in his absence, an
Assistant Secretary directed to do so by the President, shall act as secretary
of the meeting.

         (b) The Board of Directors of the corporation shall be entitled to
make such rules or regulations for the conduct of meetings of stockholders as
it shall deem necessary, appropriate or convenient. Subject to such rules and
regulations of the Board of Directors, if any, the chairman of the meeting
shall have the right and authority to prescribe such rules, regulations and
procedures and to do all such acts as, in the judgment of such chairman, are
necessary, appropriate or convenient for the proper conduct of the meeting,
including, without limitation, establishing an agenda or order of business for
the meeting, rules and procedures for maintaining order at the meeting and the
safety of those present, limitations on participation in such meeting to
stockholders of record of the corporation and their duly authorized and
constituted proxies and such other persons as the chairman shall permit,
restrictions on entry to 




                                       7.
<PAGE>   12

the meeting after the time fixed for the commencement thereof, limitations on
the time allotted to questions or comments by participants and regulation of
the opening and closing of the polls for balloting on matters which are to be
voted on by ballot. Unless and to the extent determined by the Board of
Directors or the chairman of the meeting, meetings of stockholders shall not be
required to be held in accordance with rules of parliamentary procedure.

                                  ARTICLE IV

                                   DIRECTORS

     SECTION 15. NUMBER AND TERM OF OFFICE. The authorized number of directors
of the corporation shall be fixed in accordance with the Certificate of
Incorporation. Directors need not be stockholders unless so required by the
Certificate of Incorporation. If for any cause, the directors shall not have
been elected at an annual meeting, they may be elected as soon thereafter as
convenient at a special meeting of the stockholders called for that purpose in
the manner provided in these Bylaws.

     SECTION 16. POWERS. The powers of the corporation shall be exercised, its
business conducted and its property controlled by the Board of Directors,
except as may be otherwise provided by statute or by the Certificate of
Incorporation.

     SECTION 17. CLASSES OF DIRECTORS. Subject to the rights of the holders of
any series of Preferred Stock to elect additional directors under specified
circumstances, following the closing of the Initial Public Offering, the
directors shall be divided into three classes designated as Class I, Class II
and Class III, respectively. Directors shall be assigned to each class in
accordance with a resolution or resolutions adopted by the Board of Directors.
At the first annual meeting of stockholders following the closing of the
Initial Public Offering, the term of office of the Class I directors shall
expire and Class I directors shall be elected for a full term of three years.
At the second annual meeting of stockholders following the closing of the
Initial Public Offering, the term of office of the Class II directors shall
expire and Class II directors shall be elected for a full term of three years.
At the third annual meeting of stockholders following the closing of the
Initial Public Offering, the term of office of the Class III directors shall
expire and Class III directors shall be elected for a full term of three years.
At each succeeding annual meeting of stockholders, directors shall be elected
for a full term of three years to succeed the directors of the class whose
terms expire at such annual meeting.

Notwithstanding the foregoing provisions of this section, each director shall
serve until his successor is duly elected and qualified or until his death,
resignation or removal. No decrease in the number of directors constituting the
Board of Directors shall shorten the term of any incumbent director.



                                       8.
<PAGE>   13

     SECTION 18. VACANCIES.

         (a) Unless otherwise provided in the Certificate of Incorporation, any
vacancies on the Board of Directors resulting from death, resignation,
disqualification, removal or other causes and any newly created directorships
resulting from any increase in the number of directors shall, unless the Board
of Directors determines by resolution that any such vacancies or newly created
directorships shall be filled by stockholders, except as otherwise provided by
law, be filled only by the affirmative vote of a majority of the directors then
in office, even though less than a quorum of the Board of Directors. Any
director elected in accordance with the preceding sentence shall hold office
for the remainder of the full term of the director for which the vacancy was
created or occurred and until such director's successor shall have been elected
and qualified. A vacancy in the Board of Directors shall be deemed to exist
under this Bylaw in the case of the death, removal or resignation of any
director.

         (b) If at the time of filling any vacancy or any newly created
directorship, the directors then in office shall constitute less than a
majority of the whole board (as constituted immediately prior to any such
increase), the Delaware Court of Chancery may, upon application of any
stockholder or stockholders holding at least ten percent (10%) of the total
number of the shares at the time outstanding having the right to vote for such
directors, summarily order an election to be held to fill any such vacancies or

regular meetings of the Executive Committee or any other committee appointed
pursuant to this Section 25 shall be held at such times and places as are
determined by the Board of Directors, or by any such committee, and when notice
thereof has been given to each member of such committee, no further notice of
such regular meetings need be given thereafter. Special meetings of any such
committee may be held at any place which has been determined from time to time
by such committee, and may be called by any director who is a member of such
committee, upon written notice to the members of such committee of the time and
place of such special meeting given in the manner provided for the giving of
written notice to members of the Board of Directors of the time and place of
special meetings of the Board of Directors. Notice of any special meeting of
any committee may be waived in writing at any time before or after the meeting
and will be waived by any director by attendance thereat, except when the
director attends such special meeting for the express purpose of objecting, at
the beginning of the meeting, to the transaction of any business because the
meeting is not lawfully called or convened. A majority of the authorized number
of members of any such committee shall constitute a quorum for the transaction

registrar who has signed or whose facsimile signature has been placed upon a

certificate shall state upon the face or back thereof, in full or in summary,
all of the powers, designations, preferences, and rights, and the limitations
or restrictions of the shares authorized to be issued or shall, except as

Within a reasonable time after the issuance or transfer of uncertificated
stock, the corporation shall send to the registered owner thereof a written
notice containing the information required to be set forth or stated on
certificates pursuant to this section or otherwise required by law or with
respect to this section a statement that the corporation will furnish without
charge to each stockholder who so requests the powers, designations,

issued in place of any certificate or certificates theretofore issued by the
corporation alleged to have been lost, stolen, or destroyed, upon the making of

precedent to the issuance of a new certificate or certificates, the owner of
such lost, stolen, or destroyed certificate or certificates, or his legal
representative, to agree to indemnify the corporation in such manner as it
shall require or to give the corporation a surety bond in such form and amount

corporation of any one or more classes owned by such stockholders in any manner
not prohibited by the Delaware General Corporation Law.

     SECTION 37. FIXING RECORD DATES.

         (a) In order that the corporation may determine the stockholders
entitled to notice of or to vote at any meeting of stockholders or any
adjournment thereof, the Board of Directors may fix, in advance, a record date,
which record date shall not precede the date upon 



                                      16.
<PAGE>   21

which the resolution fixing the record date is adopted by the Board of
Directors, and which record date shall, subject to applicable law, not be more
than sixty (60) nor less than ten (10) days before the date of such meeting. If
no record date is fixed by the Board of Directors, the record date for
determining stockholders entitled to notice of or to vote at a meeting of
stockholders shall be at the close of business on the day next preceding the
day on which notice is given, or if notice is waived, at the close of business
on the day next preceding the day on which the meeting is held. A determination
of stockholders of record entitled to notice of or to vote at a meeting of
stockholders shall apply to any adjournment of the meeting; provided, however,
that the Board of Directors may fix a new record date for the adjourned
meeting.

         (b) Prior to the Initial Public Offering, in order that the
corporation may determine the stockholders entitled to consent to corporate
action in writing without a meeting, the Board of Directors may fix a record
date, which record date shall not precede the date upon which the resolution
fixing the record date is adopted by the Board of Directors, and which date
shall not be more than ten (10) days after the date upon which the resolution
fixing the record date is adopted by the Board of Directors. Any stockholder of
record seeking to have the stockholders authorize or take corporate action by
written consent shall, by written notice to the Secretary, request the Board of
Directors to fix a record date. The Board of Directors shall promptly, but in
all events within ten (10) days after the date on which such a request is
received, adopt a resolution fixing the record date. If no record date has been
fixed by the Board of Directors within ten (10) days of the date on which such
a request is received, the record date for determining stockholders entitled to
consent to corporate action in writing without a meeting, when no prior action
by the Board of Directors is required by applicable law, shall be the first
date on which a signed written consent setting forth the action taken or
proposed to be taken is delivered to the corporation by delivery to its
registered office in the State of Delaware, its principal place of business or
an officer or agent of the corporation having custody of the book in which
proceedings of meetings of stockholders are recorded. Delivery made to the
corporation's registered office shall be by hand or by certified or registered
mail, return receipt requested. If no record date has been fixed by the Board
of Directors and prior action by the Board of Directors is required by law, the
record date for determining stockholders entitled to consent to corporate
action in writing without a meeting shall be at the close of business on the
day on which the Board of Directors adopts the resolution taking such prior
action.

         (c) In order that the corporation may determine the stockholders
entitled to receive payment of any dividend or other distribution or allotment
of any rights or the stockholders entitled to exercise any rights in respect of
any change, conversion or exchange of stock, or for the purpose of any other
lawful action, the Board of Directors may fix, in advance, a record date, which
record date shall not precede the date upon which the resolution fixing the
record date is adopted, and which record date shall be not more than sixty (60)
days prior to such action. If no record date is fixed, the record date for
determining stockholders for any such purpose shall be at the close of business
on the day on which the Board of Directors adopts the resolution relating
thereto.

     SECTION 38. REGISTERED STOCKHOLDERS. The corporation shall be entitled to
recognize the exclusive right of a person registered on its books as the owner
of shares to receive dividends, and to vote as such owner, and shall not be
bound to recognize any equitable or other claim to or interest in such share or
shares on the part of any other person whether or not it shall have express or
other notice thereof, except as otherwise provided by the laws of Delaware.

                      OTHER SECURITIES OF THE CORPORATION

     SECTION 39. EXECUTION OF OTHER SECURITIES. All bonds, debentures and other
corporate securities of the corporation, other than stock certificates (covered
in Section 34), may be signed by the Chairman of the Board of Directors, the
President or any Vice President, or such other person as may be authorized by
the Board of Directors, and the corporate seal impressed thereon or a facsimile
of such seal imprinted thereon and attested by the signature of the Secretary
or an Assistant Secretary, or the Chief Financial Officer or Treasurer or an
Assistant Treasurer; provided, however, that where any such bond, debenture or
other corporate security shall be authenticated by the manual signature, or
where permissible facsimile signature, of a trustee under an indenture pursuant
to which such bond, debenture or other corporate security shall be issued, the
signatures of the persons signing and attesting the corporate seal on such
bond, debenture or other corporate security may be the imprinted facsimile of
the signatures of such persons. Interest coupons appertaining to any such bond,
debenture or other corporate security, authenticated by a trustee as aforesaid,
shall be signed by the Treasurer or an Assistant Treasurer of the corporation
or such other person as may be authorized by the Board of Directors, or bear
imprinted thereon the facsimile signature of such person. In case any officer
who shall have signed or attested any bond, debenture or other corporate
security, or whose facsimile signature shall appear thereon or on any such
interest coupon, shall have ceased to be such officer before the bond,
debenture or other corporate security so signed or attested shall have been
delivered, such bond, debenture or other corporate security nevertheless may be
adopted by the corporation and issued and delivered as though the person who
signed the same or whose facsimile signature shall have been used thereon had
not ceased to be such officer of the corporation.

                                  ARTICLE IX

set aside out of any funds of the corporation available for dividends such sum
or sums as the Board

of Directors from time to time, in their absolute discretion, think proper as a
reserve or reserves to meet contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the corporation, or for such other
purpose as the Board of Directors shall think conducive to the interests of the
corporation, and the Board of Directors may modify or abolish any such reserve
in the manner in which it was created.

     SECTION 43. INDEMNIFICATION OF DIRECTORS, EXECUTIVE OFFICERS, OTHER
OFFICERS, EMPLOYEES AND OTHER AGENTS.

         (a) DIRECTORS AND EXECUTIVE OFFICERS. The corporation shall indemnify
its directors and executive officers (for the purposes of this Article XI,
"executive officers" shall have the meaning defined in Rule 3b-7 promulgated
under the 1934 Act) to the fullest extent not prohibited by the Delaware
General Corporation Law or any other applicable law; provided, however, that
the corporation may modify the extent of such indemnification by individual
contracts with its directors and executive officers; and, provided, further,
that the corporation shall not be required to indemnify any director or
executive officer in connection with any proceeding (or part thereof) initiated
by such person unless (i) such indemnification is expressly required to be made
by law, (ii) the proceeding was authorized by the Board of Directors of the
corporation, (iii) such indemnification is provided by the corporation, in its
sole discretion, pursuant to the powers vested in the corporation under the
Delaware General Corporation Law or any other applicable law or (iv) such
indemnification is required to be made under subsection (d).

         (b) OTHER OFFICERS, EMPLOYEES AND OTHER AGENTS. The corporation shall
have power to indemnify its other officers, employees and other agents as set
forth in the Delaware General Corporation Law or any other applicable law. The
Board of Directors shall have the power to delegate the determination of
whether indemnification shall be given to any such person except executive
officers to such officers or other persons as the Board of Directors shall
determine.

         (c) EXPENSES. The corporation shall advance to any person who was or
is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative
or investigative, by reason of the fact that he 



                                      19.
<PAGE>   24

is or was a director or executive officer, of the corporation, or is or was
serving at the request of the corporation as a director or executive officer of
another corporation, partnership, joint venture, trust or other enterprise,
prior to the final disposition of the proceeding, promptly following request
therefor, all expenses incurred by any director or executive officer in
connection with such proceeding upon receipt of an undertaking by or on behalf
of such person to repay said amounts if it should be determined ultimately that
such person is not entitled to be indemnified under this Bylaw or otherwise.

     Notwithstanding the foregoing, unless otherwise determined pursuant to
paragraph (e) of this Bylaw, no advance shall be made by the corporation to an
executive officer of the corporation (except by reason of the fact that such
executive officer is or was a director of the corporation in which event this
paragraph shall not apply) in any action, suit or proceeding, whether civil,
criminal, administrative or investigative, if a determination is reasonably and
promptly made (i) by the Board of Directors by a majority vote of a quorum
consisting of directors who were not parties to the proceeding, or (ii) if such
quorum is not obtainable, or, even if obtainable, a quorum of disinterested
directors so directs, by independent legal counsel in a written opinion, that
the facts known to the decision-making party at the time such determination is
made demonstrate clearly and convincingly that such person acted in bad faith
or in a manner that such person did not believe to be in or not opposed to the
best interests of the corporation.

         (d) ENFORCEMENT. Without the necessity of entering into an express
contract, all rights to indemnification and advances to directors and executive
officers under this Bylaw shall be deemed to be contractual rights and be
effective to the same extent and as if provided for in a contract between the
corporation and the director or executive officer. Any right to indemnification
or advances granted by this Bylaw to a director or executive officer shall be
enforceable by or on behalf of the person holding such right in any court of
competent jurisdiction if (i) the claim for indemnification or advances is
denied, in whole or in part, or (ii) no disposition of such claim is made
within ninety (90) days of request therefor. The claimant in such enforcement
action, if successful in whole or in part, shall be entitled to be paid also
the expense of prosecuting his claim. In connection with any claim for
indemnification, the corporation shall be entitled to raise as a defense to any
such action that the claimant has not met the standards of conduct that make it
permissible under the Delaware General Corporation Law or any other applicable
law for the corporation to indemnify the claimant for the amount claimed. In
connection with any claim by an executive officer of the corporation (except in
any action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that such executive officer is or was a
director of the corporation) for advances, the corporation shall be entitled to
raise a defense as to any such action clear and convincing evidence that such
person acted in bad faith or in a manner that such person did not believe to be
in or not opposed to the best interests of the corporation, or with respect to
any criminal action or proceeding that such person acted without reasonable
cause to believe that his conduct was lawful. Neither the failure of the
corporation (including its Board of Directors, independent legal counsel or its
stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he has met the applicable standard of conduct set forth in the Delaware
General Corporation Law or any other applicable 



                                      20.
<PAGE>   25

law, nor an actual determination by the corporation (including its Board of
Directors, independent legal counsel or its stockholders) that the claimant has
not met such applicable standard of conduct, shall be a defense to the action
or create a presumption that claimant has not met the applicable standard of
conduct. In any suit brought by a director or executive officer to enforce a
right to indemnification or to an advancement of expenses hereunder, the burden
of proving that the director or executive officer is not entitled to be
indemnified, or to such advancement of expenses, under this Article XI or
otherwise shall be on the corporation.

         (e) NON-EXCLUSIVITY OF RIGHTS. The rights conferred on any person by
this Bylaw shall not be exclusive of any other right which such person may have
or hereafter acquire under any applicable statute, provision of the Certificate
of Incorporation, Bylaws, agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding office. The corporation is
specifically authorized to enter into individual contracts with any or all of
its directors, officers, employees or agents respecting indemnification and
advances, to the fullest extent not prohibited by the Delaware General
Corporation Law, or by any other applicable law.

         (f) SURVIVAL OF RIGHTS. The rights conferred on any person by this
Bylaw shall continue as to a person who has ceased to be a director, officer,
employee or other agent and shall inure to the benefit of the heirs, executors
and administrators of such a person.

         (g) INSURANCE. To the fullest extent permitted by the Delaware General
Corporation Law or any other applicable law, the corporation, upon approval by
the Board of Directors, may purchase insurance on behalf of any person required
or permitted to be indemnified pursuant to this Bylaw.

         (h) AMENDMENTS. Any repeal or modification of this Bylaw shall only be
prospective and shall not affect the rights under this Bylaw in effect at the
time of the alleged occurrence of any action or omission to act that is the
cause of any proceeding against any agent of the corporation.

         (i) SAVING CLAUSE. If this Bylaw or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
corporation shall nevertheless indemnify each director and executive officer to
the full extent not prohibited by any applicable portion of this Bylaw that
shall not have been invalidated, or by any other applicable law. If this
Section 43 shall be invalid due to the application of the indemnification
provisions of another jurisdiction, then the corporation shall indemnify each
director and executive officer to the full to the full extent under any other
applicable law.

         (j) CERTAIN DEFINITIONS. For the purposes of this Bylaw, the following
definitions shall apply:

             (1) The term "proceeding" shall be broadly construed and shall
include, without limitation, the investigation, preparation, prosecution,
defense, settlement, 



                                      21.
<PAGE>   26

arbitration and appeal of, and the giving of testimony in, any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative.

             (2) The term "expenses" shall be broadly construed and shall
include, without limitation, court costs, attorneys' fees, witness fees, fines,
amounts paid in settlement or judgment and any other costs and expenses of any
nature or kind incurred in connection with any proceeding.

             (3) The term the "corporation" shall include, in addition to the
resulting corporation, any constituent corporation (including any constituent
of a constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers, and employees or agents, so that any person who is or was
a director, officer, employee or agent of such constituent corporation, or is
or was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall stand in the same position under the
provisions of this Bylaw with respect to the resulting or surviving corporation
as he would have with respect to such constituent corporation if its separate
existence had continued.

             (4) References to a "director," "executive officer," "officer,"
"employee," or "agent" of the corporation shall include, without limitation,
situations where such person is serving at the request of the corporation as,
respectively, a director, executive officer, officer, employee, trustee or
agent of another corporation, partnership, joint venture, trust or other
enterprise.

             (5) References to "other enterprises" shall include employee
benefit plans; references to "fines" shall include any excise taxes assessed on
a person with respect to an employee benefit plan; and references to "serving
at the request of the corporation" shall include any service as a director,
officer, employee or agent of the corporation which imposes duties on, or
involves services by, such director, officer, employee, or agent with respect
to an employee benefit plan, its participants, or beneficiaries; and a person
who acted in good faith and in a manner he reasonably believed to be in the
interest of the participants and beneficiaries of an employee benefit plan
shall be deemed to have acted in a manner "not opposed to the best interests of
the corporation" as referred to in this Bylaw.

                                  ARTICLE XII

                                    NOTICES

     SECTION 44. NOTICES.

         (a) NOTICE TO STOCKHOLDERS. Whenever, under any provisions of these
Bylaws, notice is required to be given to any stockholder, it shall be given in
writing, timely and duly deposited in the United States mail, postage prepaid,
and addressed to his last known post office address as shown by the stock
record of the corporation or its transfer agent.



                                      22.
<PAGE>   27

         (b) NOTICE TO DIRECTORS. Any notice required to be given to any
director may be given by the method stated in subsection (a), or by overnight
delivery service, facsimile, telex or telegram, except that such notice other
than one which is delivered personally shall be sent to such address as such
director shall have filed in writing with the Secretary, or, in the absence of
such filing, to the last known post office address of such director.

         (c) AFFIDAVIT OF MAILING. An affidavit of mailing, executed by a duly
authorized and competent employee of the corporation or its transfer agent
appointed with respect to the class of stock affected, specifying the name and
address or the names and addresses of the stockholder or stockholders, or
director or directors, to whom any such notice or notices was or were given,
and the time and method of giving the same, shall in the absence of fraud, be
prima facie evidence of the facts therein contained.

         (d) TIME NOTICES DEEMED GIVEN. All notices given by mail or by
overnight delivery service, as above provided, shall be deemed to have been
given as at the time of mailing, and all notices given by facsimile, telex or
telegram shall be deemed to have been given as of the sending time recorded at
time of transmission.

         (e) METHODS OF NOTICE. It shall not be necessary that the same method
of giving notice be employed in respect of all directors, but one permissible
method may be employed in respect of any one or more, and any other permissible
method or methods may be employed in respect of any other or others.

         (f) FAILURE TO RECEIVE NOTICE. The period or limitation of time within
which any stockholder may exercise any option or right, or enjoy any privilege
or benefit, or be required to act, or within which any director may exercise
any power or right, or enjoy any privilege, pursuant to any notice sent him in
the manner above provided, shall not be affected or extended in any manner by
the failure of such stockholder or such director to receive such notice.

         (g) NOTICE TO PERSON WITH WHOM COMMUNICATION IS UNLAWFUL. Whenever
notice is required to be given, under any provision of law or of the
Certificate of Incorporation or Bylaws of the corporation, to any person with
whom communication is unlawful, the giving of such notice to such person shall
not be required and there shall be no duty to apply to any governmental
authority or agency for a license or permit to give such notice to such person.
Any action or meeting which shall be taken or held without notice to any such
person with whom communication is unlawful shall have the same force and effect
as if such notice had been duly given. In the event that the action taken by
the corporation is such as to require the filing of a certificate under any
provision of the Delaware General Corporation Law, the certificate shall state,
if such is the fact and if notice is required, that notice was given to all
persons entitled to receive notice except such persons with whom communication
is unlawful.

         (h) NOTICE TO PERSON WITH UNDELIVERABLE ADDRESS. Whenever notice is
required to be given, under any provision of law or the Certificate of
Incorporation or Bylaws of the corporation, to any stockholder to whom (i)
notice of two consecutive annual meetings, and all notices of meetings or of
the taking of action by written consent without a meeting to such



                                      23.
<PAGE>   28

person during the period between such two consecutive annual meetings, or (ii)
all, and at least two, payments (if sent by first class mail) of dividends or
interest on securities during a twelve-month period, have been mailed addressed
to such person at his address as shown on the records of the corporation and
have been returned undeliverable, the giving of such notice to such person
shall not be required. Any action or meeting which shall be taken or held
without notice to such person shall have the same force and effect as if such
notice had been duly given. If any such person shall deliver to the corporation
a written notice setting forth his then current address, the requirement that
notice be given to such person shall be reinstated. In the event that the
action taken by the corporation is such as to require the filing of a
certificate under any provision of the Delaware General Corporation Law, the
certificate need not state that notice was not given to persons to whom notice
was not required to be given pursuant to this paragraph.

                                  ARTICLE XIII

                                   AMENDMENTS

     SECTION 45. AMENDMENTS. Subject to paragraph (h) of Section 43 of the
Bylaws, the Bylaws may be altered or amended or new Bylaws adopted by the
affirmative vote of at least sixty-six and two-thirds percent (66-2/3%) of the
voting power of all of the then-outstanding shares of the voting stock of the
corporation entitled to vote. The Board of Directors shall also have the power
to adopt, amend, or repeal Bylaws.

                                  ARTICLE XIV

                               LOANS TO OFFICERS

guarantee any obligation of, or otherwise assist any officer or other employee
of the corporation or of its subsidiaries, including any officer or employee
who is a Director of the corporation or its subsidiaries, whenever, in the
judgment of the Board of Directors, such loan, guarantee or assistance may
reasonably be expected to benefit the corporation. The loan, guarantee or other
assistance may be with or without interest and may be unsecured, or secured in
such manner as the Board of Directors shall approve, including, without
limitation, a pledge of shares of stock of the corporation. Nothing in these
Bylaws shall be deemed to deny, limit or restrict the powers of guaranty or
warranty of the corporation at common law or under any statute.

to time by the Board. The Board may abolish the Committee at any time and revest

Section 424(d) of the Code) stock possessing more than ten percent (10%) of the
total combined voting power of all classes of stock of the Company or of any of
its Affiliates unless the exercise price of such Incentive Stock Option is at
least one hundred ten percent (110%) of the Fair Market Value of such stock at
the date of grant and the Incentive Stock Option is not exercisable after the
expiration of five (5) years from the date of grant. To the extent required by
applicable law, the provisions of this 





                                       5.
<PAGE>   6

subsection 5(b) shall also apply to the grant of a Nonstatutory Stock Option
granted to a ten percent (10%) stockholder described in the preceding sentence.

6.   OPTION PROVISIONS.

     Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. The provisions of separate
Options need not be identical, but each Option shall include (through
incorporation of provisions hereof by reference in the Option or otherwise) the
substance of each of the following provisions:

     (a) Term. No Option shall be exercisable after the expiration of ten (10)
years from the date it was granted.

     (b) Price. The exercise price of each Incentive Stock Option shall be not
less than one hundred percent (100%) of the Fair Market Value on the date of
grant. The exercise price of each Nonstatutory Stock Option shall be not less
than fifty percent (50%) of the Fair Market Value on the date of grant.
Notwithstanding the foregoing, the Board may grant an Option with an exercise
price lower than that set forth above if such Option is granted as part of a
transaction pursuant to Section 424(a) of the Code.

     (c) Consideration. The purchase price of stock acquired pursuant to an
Option shall be paid, to the extent permitted by applicable statutes and
regulations, either (i) in cash at the time the Option is exercised, or (ii) at
the discretion of the Board or the Committee, at the time of the grant of the
Option, (A) by delivery to the Company of other common stock of the Company, (B)
according to a deferred payment or other arrangement (which may include, without
limiting the generality of the foregoing, the use of other common stock of the
Company) with the person 




                                       6.
<PAGE>   7

to whom the Option is granted or to whom the Option is transferred pursuant to
subsection 6(d), or (C) in any other form of legal consideration that may be
acceptable to the Board. In the case of any deferred payment arrangement,
interest shall be payable at least annually and shall be charged at the minimum
rate of interest necessary to avoid the treatment as interest, under any
applicable provisions of the Code, of any amounts other than amounts stated to
be interest under the deferred payment arrangement.

     (d) Transferability. An Incentive Stock Option shall not be transferable
except by will or by the laws of descent and distribution, and shall be
exercisable during the lifetime of the person to whom the Incentive Stock Option
is granted only by such person. A Nonstatutory Stock Option shall only be
transferable by the Optionee upon such terms and conditions as are set forth in
the Option Agreement for such Nonstatutory Option, as the Board or Committee
shall determine in its discretion, except that each Nonstatutory Stock Option
may be transferred to the spouse, children and lineal descendants of the
Optionee (or to a trust created solely for the benefit of the Optionee and the
foregoing persons) or to an organization exempt from taxation pursuant to
Section 501(c)(3) of the Code or to which tax deductible charitable
contributions may be made under Section 170 of the Code (excluding such
organizations classified as private foundations under applicable regulations and
rulings). The person to whom the Option is granted may, by delivering written
notice to the Company, in a form satisfactory to the Company, designate a third
party who, in the event of the death of the Optionee, shall thereafter be
entitled to exercise the Option.

     (e) Vesting. The total number of shares of stock subject to an Option may,
but need not, be allotted in periodic installments (which may, but need not, be
equal). The Option 





                                       7.
<PAGE>   8

Agreement may provide that from time to time during each of such installment
periods, the Option may become exercisable ("vest") with respect to some or all
of the shares allotted to that period, and may be exercised with respect to some
or all of the shares allotted to such period and/or any prior period as to which
the Option became vested but was not fully exercised. To the extent required by
applicable law, Options shall vest at the rate of at least twenty percent (20%)
per year. The Option may be subject to such other terms and conditions on the
time or times when it may be exercised (which may be based on performance or
other criteria) as the Board may deem appropriate. The provisions of this
subsection 6(e) are subject to any Option provisions governing the minimum
number of shares as to which an Option may be exercised. Notwithstanding any
other provisions of the Plan to the contrary, an Option shall be fully vested in
the event of an Optionee's death or total and permanent disability (as
determined by the Company in its sole discretion).

     (f) SECURITIES LAW COMPLIANCE. The Company may require any Optionee, or any
person to whom an Option is transferred under subsection 6(d), as a condition of
exercising any such Option, (1) to give written assurances satisfactory to the
Company as to the Optionee's knowledge and experience in financial and business
matters and/or to employ a purchaser representative reasonably satisfactory to
the Company who is knowledgeable and experienced in financial and business
matters, and that he or she is capable of evaluating, alone or together with the
purchaser representative, the merits and risks of exercising the Option; and (2)
to give written assurances satisfactory to the Company stating that such person
is acquiring the stock subject to the Option for such person's own account and
not with any present intention of selling or otherwise distributing the stock.
The foregoing requirements, and any assurances given pursuant 




                                       8.
<PAGE>   9

to such requirements, shall be inoperative if (i) the issuance of the shares
upon the exercise of the Option has been registered under a then currently
effective registration statement under the Securities Act of 1933, as amended
(the "Securities Act"), or (ii) as to any particular requirement, a
determination is made by counsel for the Company that such requirement need not
be met in the circumstances under the then applicable securities laws. The
Company may require the Optionee to provide such other representations, written
assurances or information which the Company shall determine is necessary,
desirable or appropriate to comply with applicable securities and other laws as
a condition of granting an Option to such Optionee or permitting the Optionee to
exercise such Option. The Company may, upon advice of counsel to the Company,
place legends on stock certificates issued under the Plan as such counsel deems
necessary or appropriate in order to comply with applicable securities laws,
including, but not limited to, legends restricting the transfer of the stock.

     (g) TERMINATION OF CONTINUOUS STATUS AS AN EMPLOYEE, DIRECTOR OR
CONSULTANT. In the event an Optionee's Continuous Status as an Employee,
Director or Consultant terminates (other than upon the Optionee's death or
disability), the Optionee may exercise his or her Option (to the extent that the
Optionee was entitled to exercise it as of the date of termination) but only
within such period of time ending on the earlier of (i) the date three (3)
months after the termination of the Optionee's Continuous Status as an Employee,
Director or Consultant, or such longer or shorter period specified in the Option
Agreement (which shall be at least thirty (30) days, if required by applicable
law), or (ii) the expiration of the term of the Option as set forth in the
Option Agreement. If, after termination, the Optionee does not exercise his or
her Option within the time specified in the Option Agreement, the Option shall
terminate, and the shares 




                                       9.
<PAGE>   10

covered by such Option shall revert to and again become available for issuance
under the Plan. Finally, an Optionee's Option Agreement may also provide that if
the exercise of the Option following the termination of the Optionee's
Continuous Status as an Employee, Director or Consultant (other than upon the
Optionee's death or disability) would be prohibited at any time solely because
the issuance of share would violate the registration requirements under the
Securities Act, then the Option shall terminate on the earlier of (i) the
expiration of the term of the Option set forth in the first paragraph of this
Section 7, or (ii) the expiration of a period of three (3) months after the
termination of the Optionee's Continuous Status as an Employee, Director or
Consultant during which the exercise of the Option would not be in violation of
such registration requirements.

     (h) DISABILITY OF OPTIONEE. In the event an Optionee's Continuous Status as
an Employee, Director or Consultant terminates as a result of the Optionee's
disability, the Optionee may exercise his or her Option (to the extent that the
Optionee was entitled to exercise it as of the date of termination), but only
within such period of time ending on the earlier of (i) the date twelve (12)
months following such termination (or such longer or shorter period specified in
the Option Agreement), or (ii) the expiration of the term of the Option as set
forth in the Option Agreement. If, at the date of termination, the Optionee is
not entitled to exercise his or her entire Option, the shares covered by the
unexercisable portion of the Option shall revert to and again become available
for issuance under the Plan. If, after termination, the Optionee does not
exercise his or her Option within the time specified herein, the Option shall
terminate, and the shares covered by such Option shall revert to and again
become available for issuance under the Plan.




                                      10.
<PAGE>   11

     (i) DEATH OF OPTIONEE. In the event of the death of an Optionee during, or
within a period specified in the Option Agreement after the termination of, the
Optionee's Continuous Status as an Employee, Director or Consultant, the Option
may be exercised (to the extent the Optionee was entitled to exercise the Option
as of the date of death) by the Optionee's estate, by a person who acquired the
right to exercise the Option by bequest or inheritance or by a person designated
to exercise the option upon the Optionee's death pursuant to subsection 6(d),
but only within the period ending on the earlier of (i) the date twelve (12)
months following the date of death (or such longer or shorter period specified
in the Option Agreement), or (ii) the expiration of the term of such Option as
set forth in the Option Agreement. If, at the time of death, the Optionee was
not entitled to exercise his or her entire Option, the shares covered by the
unexercisable portion of the Option shall revert to an again become available
for issuance under the Plan. If, after death, the Option is not exercised within
the time specified herein, the Option shall terminate, and the shares covered by
such Option shall revert to and again become available for issuance under the
Plan.

     (j) EARLY EXERCISE. The Option may, but need not, include a provision
whereby the Optionee may elect at any time while an Employee, Director or
Consultant to exercise the Option as to any part or all of the shares subject to
the Option prior to the full vesting of the Option. Any unvested shares so
purchased shall be subject to a repurchase right in favor of the Company or to
any other restriction the Board determines to be appropriate.

     (k) RIGHT OF REPURCHASE. The Option may, but need not, include a provision
whereby the Company may elect, prior to the date of the first registration of an
equity security of 




                                      11.
<PAGE>   12

the Company under Section 12 of the Exchange Act, to repurchase all or any part
of the vested shares exercised pursuant to the Option.

     (l) RIGHT OF FIRST REFUSAL. The Option may, but need not, include a
provision whereby the Company may elect, prior to the date of the first
registration of an equity security of the Company under Section 12 of the
Exchange Act, to exercise a right of first refusal following receipt of notice
from the Optionee of the intent to transfer all or any part of the shares
exercised pursuant to the Option.

     (m) WITHHOLDING. To the extent provided by the terms of an Option
Agreement, the Optionee may satisfy any federal, state or local tax withholding
obligation relating to the exercise of such Option by any of the following means
or by a combination of such means: (1) tendering a cash payment; (2) authorizing
the Company to withhold shares from the shares of the common stock otherwise
issuable to the Optionee as a result of the exercise of the Option; or (3)
delivering to the Company owned and unencumbered shares of the common stock of
the Company.

7.   COVENANTS OF THE COMPANY.

     (a) During the terms of the Options, the Company shall keep available at
all times the number of shares of stock required to satisfy such Options.

     (b) The Company shall seek to obtain from each regulatory commission or
agency having jurisdiction over the Plan such authority as may be required to
issue and sell shares of stock upon exercise of the Options; provided, however,
that this undertaking shall not require the Company to register under the
Securities Act either the Plan, any Option or any stock issued or issuable
pursuant to any such Option. If, after reasonable efforts, the Company is unable
to 




                                      12.
<PAGE>   13

obtain from any such regulatory commission or agency the authority which counsel
for the Company deems necessary for the lawful issuance and sale of stock under
the Plan, the Company shall be relieved from any liability for failure to issue
and sell stock upon exercise of such Options unless and until such authority is
obtained.

8.   USE OF PROCEEDS FROM STOCK.

     Proceeds from the sale of stock pursuant to Options shall constitute
general funds of the Company.

9.   MISCELLANEOUS.

     (a) The Board shall have the power to accelerate the time at which an
Option may first be exercised or the time during which an Option or any part
thereof will vest pursuant to subsection 6(e), notwithstanding the provisions in
the Option stating the time at which it may first be exercised or the time
during which it will vest.

     (b) Neither an Optionee nor any person to whom an Option is transferred
under subsection 6(d) shall be deemed to be the holder of, or to have any of the
rights of a holder with respect to, any shares subject to such Option unless and
until such person has satisfied all requirements for exercise of the Option
pursuant to its terms.

     (c) Nothing in the Plan or any instrument executed or Option granted
pursuant thereto shall confer upon any Employee, Director, Consultant or
Optionee any right to continue in the employ of the Company or any Affiliate (or
to continue acting as a Director or Consultant) or shall affect the right of the
Company or any Affiliate to terminate the employment of any Employee with or
without cause, the right of the Company's Board of Directors and/or the
Company's shareholders to remove any Director pursuant to the terms of the
Company's 





                                      13.
<PAGE>   14

shareholders to remove any Director pursuant to the terms of the Company's
By-Laws and applicable law, or the right to terminate the relationship of any
Consultant pursuant to the terms of such Consultant's agreement with the Company
or Affiliate.

     (d) To the extent that the aggregate Fair Market Value (determined at the
time of grant) of stock with respect to which Incentive Stock Options are
exercisable for the first time by any Optionee during any calendar year under
all plans of the Company and its Affiliates exceeds One Hundred Thousand Dollars
($100,000), the Options or portions thereof which exceed such limit (according
to the order in which they were granted) shall be treated as Nonstatutory Stock
Options.

     (e) The Board or the Committee shall have the authority to effect, at any
time and from time to time (i) the repricing of any outstanding Options under
the Plan and/or (ii) with the consent of the affected holders of Options, the
cancellation of any outstanding Options and the grant in substitution therefor
of new Options under the Plan covering the same or different numbers of shares
of common stock, but having an exercise price per share not less than (one
hundred percent (100%) of the Fair Market Value in the case of an Incentive
Stock Option or, in the case of a ten percent (10%) stockholder (as defined in
subsection 5(c)), not less than one hundred and ten percent (110%) of the Fair
Market Value) per share of Common Stock on the new grant date. Notwithstanding
the foregoing, the Board may grant an Option with an exercise price lower than
that set forth above if such Option is granted as part of a transaction to which
Section 424(c) of the Code applies.

any Option (through merger, consolidation, reorganization, reincorporation,
recapitalization, stock dividend, dividend in property other than cash, stock
split, liquidating dividend, combination of shares, exchange of shares, change
in corporate structure or other transaction not involving the receipt of
consideration by the Company), the Plan will be appropriately adjusted in the
class(es) and maximum number of shares subject to the Plan pursuant to
subsection 4(a), and the outstanding Options will be appropriately adjusted in
the class(es) and number of shares and price per share of stock subject to such
outstanding Options. Such adjustments shall be made by the Board or Committee,
the determination of which shall be final, binding and conclusive. (The
conversion of any convertible securities of the Company shall not be treated as
a "transaction not involving the receipt of consideration by the Company.")

     (b) In the event of: (1) a sale of all or substantially all of the assets
of the Company; (2) a merger or consolidation in which the Company is not the
surviving corporation; (3) a reverse merger in which the Company is the

immediately preceding the merger are converted by virtue of the merger into
other property, whether in the form of securities, cash or otherwise; or (4) the
acquisition by any person, entity or group within the meaning of Section 13(d)
or 14(d) of the Exchange Act, or any comparable successor provisions (excluding
any employee benefit plan, or related trust, sponsored or maintained by the
Company or any Affiliate of the Company) of the beneficial ownership (within the
meaning of Rule 13d-3 promulgated under the Exchange Act, or comparable
successor rule) of securities of the Company representing at least fifty

directors, then to the extent permitted by applicable law: (i) any surviving or
acquiring corporation shall assume any Options outstanding under the Plan or
shall substitute similar Options (including an option to acquire the same
consideration paid to the stockholders in the transaction described in this
subsection 10(b)) for those outstanding under the Plan, or (ii) such Options
shall continue in full force and effect. In the event any surviving or acquiring
corporation refuses to assume such Options, or to substitute similar options for
those outstanding under the Plan, then, with respect to Options held by persons
then performing services as Employees, Directors or Consultants, then such
options shall be fully vested and the time during which such Options may be
exercised shall be accelerated prior to such event and the Options terminated if
not exercised after such acceleration and at or prior to such event.

promulgated thereunder relating to Incentive Stock Options and/or to bring the
Plan and/or Incentive Stock Options granted under it into compliance therewith.

Plan shall not be impaired by any amendment of the Plan unless (i) the Company
requests the consent of the person to whom the Option was granted and (ii) such
person consents in writing.

     (e) The Board at any time, and from time to time, may amend the terms of
any one or more Options; provided, however, that the rights and obligations

         (iii) To amend the Plan or a Stock Award as provided in Section 12.

         (iv) Generally, to exercise such powers and to perform such acts as the
Board deems necessary or expedient to promote the best interests of the Company
which are not in conflict with the provisions of the Plan.

     (c)  DELEGATION TO COMMITTEE.

         (i) GENERAL. The Board may delegate administration of the Plan to a
Committee or Committees of one (1) or more members of the Board, and the term
"Committee" shall apply to any person or persons to whom such authority has been
delegated. If administration is delegated to a Committee, the Committee shall
have, in connection with the administration of the Plan, the powers theretofore
possessed by the Board, including the power to delegate to a subcommittee any of
the administrative powers the Committee is authorized to exercise (and
references in this Plan to the Board shall thereafter be to the Committee or
subcommittee), subject, however, to such resolutions, not inconsistent with the
provisions of the Plan, as may be adopted from time to time by the Board. The
Board may abolish the Committee at any time and revest in the Board the
administration of the Plan.

         (ii) COMMITTEE COMPOSITION WHEN COMMON STOCK IS PUBLICLY TRADED. At
such time as the Common Stock is publicly traded, in the discretion of the
Board, a Committee may consist solely of two or more Outside Directors, in
accordance with Section 162(m) of the Code, and/or solely of two or more
Non-Employee Directors, in accordance with Rule 16b-3. Within the scope of such
authority, the Board or the Committee may (1) delegate to a committee of one or
more members of the Board who are not Outside Directors the authority to grant
Stock Awards to eligible persons who are either (a) not then Covered Employees
and are not expected to be Covered Employees at the time of recognition of
income resulting from such Stock Award or (b) not persons with respect to whom
the Company wishes to comply with Section 162(m) of the Code and/or) (2)
delegate to a committee of one or more members of the Board who are not
Non-Employee Directors the authority to grant Stock Awards to eligible persons
who are not then subject to Section 16 of the Exchange Act.

4.   SHARES SUBJECT TO THE PLAN.

     (a) SHARE RESERVE. Subject to the provisions of Section 11 relating to
adjustments upon changes in Common Stock, the Common Stock that may be issued
pursuant to Stock Awards shall not exceed in the aggregate four hundred
twenty-five thousand seven hundred sixty-three (425,763) shares of Common Stock.

     (b) REVERSION OF SHARES TO THE SHARE RESERVE. If any Stock Award shall for
any reason expire or otherwise terminate, in whole or in part, without having
been exercised in full, the shares of Common Stock not acquired under such Stock
Award shall revert to and again



                                        5
<PAGE>   6

become available for issuance under the Plan. Shares subject to stock
appreciation rights exercised in accordance with the Plan shall not be available
for subsequent issuance under the Plan. If any Common Stock acquired pursuant to
the exercise of an Option shall for any reason be repurchased by the Company
under an unvested share repurchase option provided under the Plan, the stock
repurchased by the Company under such repurchase option shall not revert to and
again become available for issuance under the Plan.

     (c) SOURCE OF SHARES. The shares of Common Stock subject to the Plan may be
unissued shares or reacquired shares, bought on the market or otherwise.

     (d) SHARE RESERVE LIMITATION. Prior to the Listing Date and to the extent
then required by Section 260.140.45 of Title 10 of the California Code of
Regulations, the total number of shares of Common Stock issuable upon exercise
of all outstanding Options and the total number of shares of Common Stock
provided for under any stock bonus or similar plan of the Company shall not
exceed the applicable percentage as calculated in accordance with the conditions
and exclusions of Section 260.140.45 of Title 10 of the California Code of
Regulations, based on the shares of Common Stock of the Company that are
outstanding at the time the calculation is made.

5.   ELIGIBILITY.

     (a) ELIGIBILITY FOR SPECIFIC STOCK AWARDS. Incentive Stock Options may be
granted only to Employees. Stock Awards other than Incentive Stock Options may
be granted to Employees, Directors and Consultants.

     (b) TEN PERCENT STOCKHOLDERS.

         (i) A Ten Percent Stockholder shall not be granted an Incentive Stock
Option unless the exercise price of such Option is at least one hundred ten
percent (110%) of the Fair Market Value of the Common Stock at the date of grant
and the Option is not exercisable after the expiration of five (5) years from
the date of grant.

         (ii) Prior to the Listing Date, a Ten Percent Stockholder shall not be
granted a Nonstatutory Stock Option unless the exercise price of such Option is
at least (i) one hundred ten percent (110%) of the Fair Market Value of the
Common Stock at the date of grant or (ii) such lower percentage of the Fair
Market Value of the Common Stock at the date of grant as is permitted by Section
260.140.41 of Title 10 of the California Code of Regulations at the time of the
grant of the Option.

         (iii) Prior to the Listing Date, a Ten Percent Stockholder shall not be
granted a restricted stock award unless the purchase price of the restricted
stock is at least (i) one hundred percent (100%) of the Fair Market Value of the
Common Stock at the date of grant or (ii) such lower percentage of the Fair
Market Value of the Common Stock at the date of grant as is permitted by Section
260.140.41 of Title 10 of the California Code of Regulations at the time of the
grant of the Option.

                                       6
<PAGE>   7

     (c) SECTION 162(m) LIMITATION. Subject to the provisions of Section 11
relating to adjustments upon changes in the shares of Common Stock, no Employee
shall be eligible to be granted Options and/or stock appreciation rights
covering more than one hundred thousand (100,000) shares of Common Stock during
any calendar year. This subsection 5(c) shall not apply prior to the Listing
Date and, following the Listing Date, this subsection 5(c) shall not apply until
(i) the earliest of: (1) the first material modification of the Plan (including
any increase in the number of shares of Common Stock reserved for issuance under
the Plan in accordance with Section 4); (2) the issuance of all of the shares of
Common Stock reserved for issuance under the Plan; (3) the expiration of the
Plan; or (4) the first meeting of stockholders at which Directors are to be
elected that occurs after the close of the third calendar year following the
calendar year in which occurred the first registration of an equity security
under Section 12 of the Exchange Act; or (ii) such other date required by
Section 162(m) of the Code and the rules and regulations promulgated thereunder.

     (d) ELIGIBILITY OF CONSULTANTS PRIOR TO THE LISTING DATE. Prior to the
Listing Date, a Consultant shall not be eligible for the grant of a Stock Award
if, at the time of grant, the offer and sale of the Company's securities to such
Consultant are not exempt under Rule 701 of the Securities Act ("Rule 701")
because of the nature of the services that the Consultant is providing to the
Company unless the Board determines that such grant need not comply with the
requirements of Rule 701 and can satisfy another exemption under the Securities
Act.

     (e) ELIGIBILITY OF CONSULTANTS FROM AND AFTER THE LISTING DATE. From and
after the Listing Date, a Consultant shall not be eligible for the grant of a
Stock Award if, at the time of grant, Form S-8 under the Securities Act is not
available to register the offer and sale of the Company's securities to such
Consultant because of the nature of the services that the Consultant is
providing to the Company unless the Board determines that such securities either
should be registered in another manner under the Securities Act or are not
required to be registered under the Securities Act.

6.   OPTION PROVISIONS.

     Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. All Options shall be separately
designated Incentive Stock Options or Nonstatutory Stock Options at the time of
grant, and, if certificates are issued, a separate certificate or certificates
will be issued for shares of Common Stock purchased on exercise of each type of
Option. The provisions of separate Options need not be identical, but each
Option shall include (through incorporation of provisions hereof by reference in
the Option or otherwise) the substance of each of the following provisions:

     (a) TERM. Subject to the provisions of subsection 5(b) regarding Ten
Percent Stockholders, no Option shall be exercisable after the expiration of ten
(10) years from the date it was granted.

     (b) EXERCISE PRICE OF AN INCENTIVE STOCK OPTION. Subject to the provisions
of subsection 5(b) regarding Ten Percent Stockholders, the exercise price of
each Incentive Stock Option shall be not less than one hundred percent (100%) of
the Fair Market Value of 


                                       7
<PAGE>   8

the Common Stock subject to the Option on the date the Option is granted.
Notwithstanding the foregoing, an Incentive Stock Option may be granted with an
exercise price lower than that set forth in the preceding sentence if such
Option is granted pursuant to an assumption or substitution for another option
in a manner satisfying the provisions of Section 424(a) of the Code.

     (c) EXERCISE PRICE OF A NONSTATUTORY STOCK OPTION. Subject to the
provisions of subsection 5(b) regarding Ten Percent Stockholders, the exercise
price of each Nonstatutory Stock Option granted prior to the Listing Date shall
be not less than eighty-five percent (85%) of the Fair Market Value of the
Common Stock subject to the Option on the date the Option is granted. The
exercise price of each Nonstatutory Stock Option granted on or after the Listing
Date shall be not less than eighty-five percent (85%) of the Fair Market Value
of the Common Stock subject to the Option on the date the Option is granted.
Notwithstanding the foregoing, a Nonstatutory Stock Option may be granted with
an exercise price lower than that set forth in the preceding sentence if such
Option is granted pursuant to an assumption or substitution for another option
in a manner satisfying the provisions of Section 424(a) of the Code.

     (d) CONSIDERATION. The purchase price of Common Stock acquired pursuant to
an Option shall be paid, to the extent permitted by applicable statutes and
regulations, either (i) in cash at the time the Option is exercised or (ii) at
the discretion of the Board at the time of the grant of the Option (or
subsequently in the case of a Nonstatutory Stock Option) (1) by delivery to the
Company of other Common Stock, (2) according to a deferred payment or other
similar arrangement with the Optionholder or (3) in any other form of legal
consideration that may be acceptable to the Board; provided, however, that at
any time that the Company is incorporated in Delaware, payment of the Common
Stock's "par value," as defined in the Delaware General Corporation Law, shall
not be made by deferred payment.

     In the case of any deferred payment arrangement, interest shall be
compounded at least annually and shall be charged at the minimum rate of
interest necessary to avoid the treatment as interest, under any applicable
provisions of the Code, of any amounts other than amounts stated to be interest
under the deferred payment arrangement.

     (e) TRANSFERABILITY OF AN INCENTIVE STOCK OPTION. An Incentive Stock Option
shall not be transferable except by will or by the laws of descent and
distribution and shall be exercisable during the lifetime of the Optionholder
only by the Optionholder. Notwithstanding the foregoing, the Optionholder may,
by delivering written notice to the Company, in a form satisfactory to the
Company, designate a third party who, in the event of the death of the
Optionholder, shall thereafter be entitled to exercise the Option.

     (f) TRANSFERABILITY OF A NONSTATUTORY STOCK OPTION. A Nonstatutory Stock
Option granted prior to the Listing Date shall not be transferable except by
will or by the laws of descent and distribution and, to the extent provided in
the Option Agreement, to such further extent as permitted by Section
260.140.41(d) of Title 10 of the California Code of Regulations at the time of
the grant of the Option, and shall be exercisable during the lifetime of the
Optionholder only by the Optionholder. A Nonstatutory Stock 



                                        8
<PAGE>   9

Option granted on or after the Listing Date shall be transferable to the extent
provided in the Option Agreement. If the Nonstatutory Stock Option does not
provide for transferability, then the Nonstatutory Stock Option shall not be
transferable except by will or by the laws of descent and distribution and shall
be exercisable during the lifetime of the Optionholder only by the Optionholder.
Notwithstanding the foregoing, the Optionholder may, by delivering written
notice to the Company, in a form satisfactory to the Company, designate a third
party who, in the event of the death of the Optionholder, shall thereafter be
entitled to exercise the Option.

     (g) VESTING GENERALLY. The total number of shares of Common Stock subject
to an Option may, but need not, vest and therefore become exercisable in
periodic installments that may, but need not, be equal. The Option may be
subject to such other terms and conditions on the time or times when it may be
exercised (which may be based on performance or other criteria) as the Board may
deem appropriate. The vesting provisions of individual Options may vary. The
provisions of this subsection 6(g) are subject to any Option provisions
governing the minimum number of shares of Common Stock as to which an Option may
be exercised.

     (h) MINIMUM VESTING PRIOR TO THE LISTING DATE. Notwithstanding the
foregoing subsection 6(g), to the extent that the following restrictions on
vesting are required by Section 260.140.41(f) of Title 10 of the California Code
of Regulations at the time of the grant of the Option, then:

         (i) Options granted prior to the Listing Date to an Employee who is not
an Officer, Director or Consultant shall provide for vesting of the total number
of shares of Common Stock at a rate of at least twenty percent (20%) per year
over five (5) years from the date the Option was granted, subject to reasonable
conditions such as continued employment; and

         (ii) Options granted prior to the Listing Date to Officers, Directors
or Consultants may be made fully exercisable, subject to reasonable conditions
such as continued employment, at any time or during any period established by
the Company.

     (i) TERMINATION OF CONTINUOUS SERVICE. In the event an Optionholder's
Continuous Service terminates (other than upon the Optionholder's death or
Disability), the Optionholder may exercise his or her Option (to the extent that
the Optionholder was entitled to exercise such Option as of the date of
termination) but only within such period of time ending on the earlier of (i)
the date three (3) months following the termination of the Optionholder's
Continuous Service (or such longer or shorter period specified in the Option
Agreement, which period shall not be less than thirty (30) days for Options
granted prior to the Listing Date unless such termination is for cause), or (ii)
the expiration of the term of the Option as set forth in the Option Agreement.
If, after termination, the Optionholder does not exercise his or her Option
within the time specified in the Option Agreement, the Option shall terminate.

     (j) EXTENSION OF TERMINATION DATE. An Optionholder's Option Agreement may
also provide that if the exercise of the Option following the termination of the
Optionholder's Continuous Service (other than upon the Optionholder's death or
Disability) would be prohibited at any time solely because the issuance of
shares of Common Stock would violate the registration requirements under the
Securities Act, then the Option shall terminate on the earlier



                                        9
<PAGE>   10

of (i) the expiration of the term of the Option set forth in subsection 6(a) or
(ii) the expiration of a period of three (3) months after the termination of the
Optionholder's Continuous Service during which the exercise of the Option would
not be in violation of such registration requirements.

     (k) DISABILITY OF OPTIONHOLDER. In the event that an Optionholder's
Continuous Service terminates as a result of the Optionholder's Disability, the
Optionholder may exercise his or her Option (to the extent that the Optionholder
was entitled to exercise such Option as of the date of termination), but only
within such period of time ending on the earlier of (i) the date twelve (12)
months following such termination (or such longer or shorter period specified in
the Option Agreement, which period shall not be less than six (6) months for
Options granted prior to the Listing Date) or (ii) the expiration of the term of
the Option as set forth in the Option Agreement. If, after termination, the
Optionholder does not exercise his or her Option within the time specified
herein, the Option shall terminate.

     (l) DEATH OF OPTIONHOLDER. In the event (i) an Optionholder's Continuous
Service terminates as a result of the Optionholder's death or (ii) the
Optionholder dies within the period (if any) specified in the Option Agreement
after the termination of the Optionholder's Continuous Service for a reason
other than death, then the Option may be exercised (to the extent the
Optionholder was entitled to exercise such Option as of the date of death) by
the Optionholder's estate, by a person who acquired the right to exercise the
Option by bequest or inheritance or by a person designated to exercise the
option upon the Optionholder's death pursuant to subsection 6(e) or 6(f), but
only within the period ending on the earlier of (1) the date eighteen (18)
months following the date of death (or such longer or shorter period specified
in the Option Agreement, which period shall not be less than six (6) months for
Options granted prior to the Listing Date) or (2) the expiration of the term of
such Option as set forth in the Option Agreement. If, after death, the Option is
not exercised within the time specified herein, the Option shall terminate.

     (m) EARLY EXERCISE. The Option may, but need not, include a provision
whereby the Optionholder may elect at any time before the Optionholder's
Continuous Service terminates to exercise the Option as to any part or all of
the shares of Common Stock subject to the Option prior to the full vesting of
the Option. Subject to the "Repurchase Limitation" in subsection 10(h), any
unvested shares of Common Stock so purchased may be subject to a repurchase
option in favor of the Company or to any other restriction the Board determines
to be appropriate.

     (n) RIGHT OF REPURCHASE. Subject to the "Repurchase Limitation" in
subsection 10(h), the Option may, but need not, include a provision whereby the
Company may elect, prior to the Listing Date, to repurchase all or any part of
the vested shares of Common Stock acquired by the Optionholder pursuant to the
exercise of the Option.

     (o) RIGHT OF FIRST REFUSAL. The Option may, but need not, include a
provision whereby the Company may elect, prior to the Listing Date, to exercise
a right of first refusal following receipt of notice from the Optionholder of
the intent to transfer all or any part of the shares of Common Stock received
upon the exercise of the Option. Except as expressly provided



                                       10
<PAGE>   11

in this subsection 6(o), such right of first refusal shall otherwise comply with
any applicable provisions of the Bylaws of the Company.

     (p) RE-LOAD OPTIONS. Without in any way limiting the authority of the Board
to make or not to make grants of Options hereunder, the Board shall have the
authority (but not an obligation) to include as part of any Option Agreement a
provision entitling the Optionholder to a further Option (a "Re-Load Option") in
the event the Optionholder exercises the Option evidenced by the Option
Agreement, in whole or in part, by surrendering other shares of Common Stock in
accordance with this Plan and the terms and conditions of the Option Agreement.
Any such Re-Load Option shall (i) provide for a number of shares of Common Stock
equal to the number of shares of Common Stock surrendered as part or all of the
exercise price of such Option; (ii) have an expiration date which is the same as
the expiration date of the Option the exercise of which gave rise to such
Re-Load Option; and (iii) have an exercise price which is equal to one hundred
percent (100%) of the Fair Market Value of the Common Stock subject to the
Re-Load Option on the date of exercise of the original Option. Notwithstanding
the foregoing, a Re-Load Option shall be subject to the same exercise price and
term provisions heretofore described for Options under the Plan.

         Any such Re-Load Option may be an Incentive Stock Option or a
Nonstatutory Stock Option, as the Board may designate at the time of the grant
of the original Option; provided, however, that the designation of any Re-Load
Option as an Incentive Stock Option shall be subject to the one hundred thousand
dollar ($100,000) annual limitation on the exercisability of Incentive Stock
Options described in subsection 10(d) and in Section 422(d) of the Code. There
shall be no Re-Load Options on a Re-Load Option. Any such Re-Load Option shall
be subject to the availability of sufficient shares of Common Stock under
subsection 4(a) and the "Section 162(m) Limitation" on the grants of Options
under subsection 5(c) and shall be subject to such other terms and conditions as
the Board may determine which are not inconsistent with the express provisions
of the Plan regarding the terms of Options.

7.   PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS.

     (a) STOCK BONUS AWARDS. Each stock bonus agreement shall be in such form
and shall contain such terms and conditions as the Board shall deem appropriate.
The terms and conditions of stock bonus agreements may change from time to time,
and the terms and conditions of separate stock bonus agreements need not be
identical, but each stock bonus agreement shall include (through incorporation
of provisions hereof by reference in the agreement or otherwise) the substance
of each of the following provisions:

         (i) CONSIDERATION. A stock bonus may be awarded in consideration for
past services actually rendered to the Company or an Affiliate for its benefit.

         (ii) VESTING. Subject to the "Repurchase Limitation" in subsection
10(h), shares of Common Stock awarded under the stock bonus agreement may, but
need not, be subject to a share repurchase option in favor of the Company in
accordance with a vesting schedule to be determined by the Board.


                                       11
<PAGE>   12

         (iii) TERMINATION OF PARTICIPANT'S CONTINUOUS SERVICE. Subject to the
"Repurchase Limitation" in subsection 10(h), in the event a Participant's
Continuous Service terminates, the Company may reacquire any or all of the
shares of Common Stock held by the Participant which have not vested as of the
date of termination under the terms of the stock bonus agreement.

         (iv) TRANSFERABILITY. For a stock bonus award made before the Listing
Date, rights to acquire shares of Common Stock under the stock bonus agreement
shall not be transferable except by will or by the laws of descent and
distribution and shall be exercisable during the lifetime of the Participant
only by the Participant. For a stock bonus award made on or after the Listing
Date, rights to acquire shares of Common Stock under the stock bonus agreement
shall be transferable by the Participant only upon such terms and conditions as
are set forth in the stock bonus agreement, as the Board shall determine in its
discretion, so long as Common Stock awarded under the stock bonus agreement
remains subject to the terms of the stock bonus agreement.

     (b) RESTRICTED STOCK AWARDS. Each restricted stock purchase agreement shall
be in such form and shall contain such terms and conditions as the Board shall
deem appropriate. The terms and conditions of the restricted stock purchase
agreements may change from time to time, and the terms and conditions of
separate restricted stock purchase agreements need not be identical, but each
restricted stock purchase agreement shall include (through incorporation of
provisions hereof by reference in the agreement or otherwise) the substance of
each of the following provisions:

         (i) PURCHASE PRICE. Subject to the provisions of subsection 5(b)
regarding Ten Percent Stockholders, the purchase price under each restricted
stock purchase agreement shall be such amount as the Board shall determine and
designate in such restricted stock purchase agreement. For restricted stock
awards made prior to the Listing Date, the purchase price shall not be less than
eighty-five (85%) of the Common Stock's Fair Market Value on the date such award
is made or at the time the purchase is consummated. For restricted stock awards
made on or after the Listing Date, the purchase price shall not be less than
eighty-five percent (85%) of the Common Stock's Fair Market Value on the date
such award is made or at the time the purchase is consummated.

         (ii) CONSIDERATION. The purchase price of Common Stock acquired
pursuant to the restricted stock purchase agreement shall be paid either: (i) in
cash at the time of purchase; (ii) at the discretion of the Board, according to
a deferred payment or other similar arrangement with the Participant; or (iii)
in any other form of legal consideration that may be acceptable to the Board in
its discretion; provided, however, that at any time that the Company is
incorporated in Delaware, then payment of the Common Stock's "par value," as
defined in the Delaware General Corporation Law, shall not be made by deferred
payment.

         (iii) VESTING. Subject to the "Repurchase Limitation" in subsection
10(h), shares of Common Stock acquired under the restricted stock purchase
agreement may, but need not, be subject to a share repurchase option in favor of
the Company in accordance with a vesting schedule to be determined by the Board.


                                       12
<PAGE>   13

         (iv) TERMINATION OF PARTICIPANT'S CONTINUOUS SERVICE. Subject to the
"Repurchase Limitation" in subsection 10(h), in the event a Participant's
Continuous Service terminates, the Company may repurchase or otherwise reacquire
any or all of the shares of Common Stock held by the Participant which have not
vested as of the date of termination under the terms of the restricted stock
purchase agreement.

         (v) TRANSFERABILITY. For a restricted stock award made before the
Listing Date, rights to acquire shares of Common Stock under the restricted
stock purchase agreement shall not be transferable except by will or by the laws
of descent and distribution and shall be exercisable during the lifetime of the
Participant only by the Participant. For a restricted stock award made on or
after the Listing Date, rights to acquire shares of Common Stock under the
restricted stock purchase agreement shall be transferable by the Participant
only upon such terms and conditions as are set forth in the restricted stock
purchase agreement, as the Board shall determine in its discretion, so long as
Common Stock awarded under the restricted stock purchase agreement remains
subject to the terms of the restricted stock purchase agreement.

     (c)  STOCK APPRECIATION RIGHTS.

         (i) AUTHORIZED RIGHTS. The following three types of stock appreciation
rights shall be authorized for issuance under the Plan:

             (1) TANDEM RIGHTS. A "Tandem Right" means a stock appreciation
right granted appurtenant to an Option which is subject to the same terms and
conditions applicable to the particular Option grant to which it pertains with
the following exceptions. The Tandem Right shall require the holder to elect
between the exercise of the underlying Option for shares of Common Stock and the
surrender, in whole or in part, of such Option for an appreciation distribution.
The appreciation distribution payable on the exercised Tandem Right shall be in
cash (or, if so provided, in an equivalent number of shares of Common Stock
based on Fair Market Value on the date of the Option surrender) in an amount up
to the excess of (A) the Fair Market Value (on the date of the Option surrender)
of the number of shares of Common Stock covered by that portion of the
surrendered Option in which the Optionholder is vested over (B) the aggregate
exercise price payable for such vested shares.

             (2) CONCURRENT RIGHTS. A "Concurrent Right" means a stock
appreciation right granted appurtenant to an Option which applies to all or a
portion of the shares of Common Stock subject to the underlying Option and which
is subject to the same terms and conditions applicable to the particular Option
grant to which it pertains with the following exceptions. A Concurrent Right
shall be exercised automatically at the same time the underlying Option is
exercised with respect to the particular shares of Common Stock to which the
Concurrent Right pertains. The appreciation distribution payable on the
exercised Concurrent Right shall be in cash (or, if so provided, in an
equivalent number of shares of Common Stock based on Fair Market Value on the
date of the exercise of the Concurrent Right) in an amount equal to such portion
as determined by the Board at the time of the grant of the excess of (A) the
aggregate Fair Market Value (on the date of the exercise of the Concurrent
Right) of the vested shares of Common Stock purchased under the underlying
Option which 



                                       13
<PAGE>   14
have Concurrent Rights appurtenant to them over (B) the aggregate exercise price
paid for such shares.

             (3) INDEPENDENT RIGHTS. An "Independent Right" means a stock
appreciation right granted independently of any Option but which is subject to
the same terms and conditions applicable to a Nonstatutory Stock Option with the
following exceptions. An Independent Right shall be denominated in share
equivalents. The appreciation distribution payable on the exercised Independent
Right shall be not greater than an amount equal to the excess of (a) the
aggregate Fair Market Value (on the date of the exercise of the Independent
Right) of a number of shares of Company stock equal to the number of share
equivalents in which the holder is vested under such Independent Right, and with
respect to which the holder is exercising the Independent Right on such date,
over (b) the aggregate Fair Market Value (on the date of the grant of the
Independent Right) of such number of shares of Company stock. The appreciation
distribution payable on the exercised Independent Right shall be in cash or, if
so provided, in an equivalent number of shares of Common Stock based on Fair
Market Value on the date of the exercise of the Independent Right.

         (ii) RELATIONSHIP TO OPTIONS. Stock appreciation rights appurtenant to
Incentive Stock Options may be granted only to Employees. The "Section 162(m)
Limitation" provided in subsection 5(c) and any authority to reprice Options
shall apply as well to the grant of stock appreciation rights.

         (iii) EXERCISE. To exercise any outstanding stock appreciation right,
the holder shall provide written notice of exercise to the Company in compliance
with the provisions of the Stock Award Agreement evidencing such right. Except
as provided in subsection 5(c) regarding the "Section 162(m) Limitation," no
limitation shall exist on the aggregate amount of cash payments that the Company
may make under the Plan in connection with the exercise of a stock appreciation
right.

8.   COVENANTS OF THE COMPANY.

     (a) AVAILABILITY OF SHARES. During the terms of the Stock Awards, the
Company shall keep available at all times the number of shares of Common Stock
required to satisfy such Stock Awards.

     (b) SECURITIES LAW COMPLIANCE. The Company shall seek to obtain from each
regulatory commission or agency having jurisdiction over the Plan such authority
as may be required to grant Stock Awards and to issue and sell shares of Common
Stock upon exercise of the Stock Awards; provided, however, that this
undertaking shall not require the Company to register under the Securities Act
the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any
such Stock Award. If, after reasonable efforts, the Company is unable to obtain
from any such regulatory commission or agency the authority which counsel for
the Company deems necessary for the lawful issuance and sale of Common Stock
under the Plan, the Company shall be relieved from any liability for failure to
issue and sell Common Stock upon exercise of such Stock Awards unless and until
such authority is obtained.

9.   USE OF PROCEEDS FROM STOCK.

     Proceeds from the sale of Common Stock pursuant to Stock Awards shall
constitute general funds of the Company.

10.  MISCELLANEOUS.

     (a) ACCELERATION OF EXERCISABILITY AND VESTING. The Board shall have the
power to accelerate the time at which a Stock Award may first be exercised or
the time during which a Stock Award or any part thereof will vest in accordance
with the Plan, notwithstanding the provisions in the Stock Award stating the
time at which it may first be exercised or the time during which it will vest.

     (b) STOCKHOLDER RIGHTS. No Participant shall be deemed to be the holder of,
or to have any of the rights of a holder with respect to, any shares of Common
Stock subject to such Stock Award unless and until such Participant has
satisfied all requirements for exercise of the Stock Award pursuant to its
terms.

     (c) NO EMPLOYMENT OR OTHER SERVICE RIGHTS. Nothing in the Plan or any
instrument executed or Stock Award granted pursuant thereto shall confer upon
any Participant any right to continue to serve the Company or an Affiliate in
the capacity in effect at the time the Stock Award was granted or shall affect
the right of the Company or an Affiliate to terminate (i) the employment of an
Employee with or without notice and with or without cause, (ii) the service of a
Consultant pursuant to the terms of such Consultant's agreement with the Company
or an Affiliate or (iii) the service of a Director pursuant to the Bylaws of the
Company or an Affiliate, and any applicable provisions of the corporate law of
the state in which the Company or the Affiliate is incorporated, as the case may
be.

     (d) INCENTIVE STOCK OPTION $100,000 LIMITATION. To the extent that the
aggregate Fair Market Value (determined at the time of grant) of Common Stock
with respect to which Incentive Stock Options are exercisable for the first time
by any Optionholder during any calendar year (under all plans of the Company and
its Affiliates) exceeds one hundred thousand dollars ($100,000), the Options or
portions thereof which exceed such limit (according to the order in which they
were granted) shall be treated as Nonstatutory Stock Options.

     (e) INVESTMENT ASSURANCES. The Company may require a Participant, as a
condition of exercising or acquiring Common Stock under any Stock Award, (i) to
give written assurances satisfactory to the Company as to the Participant's
knowledge and experience in financial and business matters and/or to employ a
purchaser representative reasonably satisfactory to the Company who is
knowledgeable and experienced in financial and business matters and that he or
she is capable of evaluating, alone or together with the purchaser
representative, the merits and risks of exercising the Stock Award; and (ii) to
give written assurances satisfactory to the Company stating that the Participant
is acquiring Common Stock subject to the Stock Award for the Participant's own
account and not with any present intention of selling or otherwise distributing
the Common Stock. The foregoing requirements, and any assurances given pursuant
to such requirements, shall be inoperative if (iii) the issuance of the shares
of Common Stock


                                       15
<PAGE>   16
upon the exercise or acquisition of Common Stock under the Stock Award has been
registered under a then currently effective registration statement under the
Securities Act or (iv) as to any particular requirement, a determination is made
by counsel for the Company that such requirement need not be met in the
circumstances under the then applicable securities laws. The Company may, upon
advice of counsel to the Company, place legends on stock certificates issued
under the Plan as such counsel deems necessary or appropriate in order to comply
with applicable securities laws, including, but not limited to, legends
restricting the transfer of the Common Stock.

     (f) WITHHOLDING OBLIGATIONS. To the extent provided by the terms of a Stock
Award Agreement, the Participant may satisfy any federal, state or local tax
withholding obligation relating to the exercise or acquisition of Common Stock
under a Stock Award by any of the following means (in addition to the Company's
right to withhold from any compensation paid to the Participant by the Company)
or by a combination of such means: (i) tendering a cash payment; (ii)
authorizing the Company to withhold shares of Common Stock from the shares of
Common Stock otherwise issuable to the participant as a result of the exercise
or acquisition of Common Stock under the Stock Award; or (iii) delivering to the
Company owned and unencumbered shares of Common Stock.

     (g) INFORMATION OBLIGATION. Prior to the Listing Date, to the extent
required by Section 260.140.46 of Title 10 of the California Code of
Regulations, the Company shall deliver financial statements to Participants at
least annually. This subsection 10(g) shall not apply to key Employees whose
duties in connection with the Company assure them access to equivalent
information.

     (h) REPURCHASE LIMITATION. The terms of any repurchase option shall be
specified in the Stock Award and may be either at Fair Market Value at the time
of repurchase or at not less than the original purchase price. To the extent
required by Section 260.140.41 and Section 260.140.42 of Title 10 of the
California Code of Regulations at the time a Stock Award is made, any repurchase
option contained in a Stock Award granted prior to the Listing Date to a person
who is not an Officer, Director or Consultant shall be upon the terms described
below:

         (i) FAIR MARKET VALUE. If the repurchase option gives the Company the
right to repurchase the shares of Common Stock upon termination of employment at
not less than the Fair Market Value of the shares of Common Stock to be
purchased on the date of termination of Continuous Service, then (i) the right
to repurchase shall be exercised for cash or cancellation of purchase money
indebtedness for the shares of Common Stock within ninety (90) days of
termination of Continuous Service (or in the case of shares of Common Stock
issued upon exercise of Stock Awards after such date of termination, within
ninety (90) days after the date of the exercise) or such longer period as may be
agreed to by the Company and the Participant (for example, for purposes of
satisfying the requirements of Section 1202(c)(3) of the Code regarding
"qualified small business stock") and (ii) the right terminates when the shares
of Common Stock become publicly traded.

         (ii) ORIGINAL PURCHASE PRICE. If the repurchase option gives the
Company the right to repurchase the shares of Common Stock upon termination of
Continuous Service at the 


                                       16
<PAGE>   17
original purchase price, then (i) the right to repurchase at the original
purchase price shall lapse at the rate of at least twenty percent (20%) of the
shares of Common Stock per year over five (5) years from the date the Stock
Award is granted (without respect to the date the Stock Award was exercised or
became exercisable) and (ii) the right to repurchase shall be exercised for cash
or cancellation of purchase money indebtedness for the shares of Common Stock
within ninety (90) days of termination of Continuous Service (or in the case of
shares of Common Stock issued upon exercise of Options after such date of
termination, within ninety (90) days after the date of the exercise) or such
longer period as may be agreed to by the Company and the Participant (for
example, for purposes of satisfying the requirements of Section 1202(c)(3) of
the Code regarding "qualified small business stock").

11.  ADJUSTMENTS UPON CHANGES IN STOCK.

     (a) CAPITALIZATION ADJUSTMENTS. If any change is made in the Common Stock
subject to the Plan, or subject to any Stock Award, without the receipt of
consideration by the Company (through merger, consolidation, reorganization,
recapitalization, reincorporation, stock dividend, dividend in property other
than cash, stock split, liquidating dividend, combination of shares, exchange of
shares, change in corporate structure or other transaction not involving the
receipt of consideration by the Company), the Plan will be appropriately
adjusted in the class(es) and maximum number of securities subject to the Plan
pursuant to subsection 4(a) and the maximum number of securities subject to
award to any person pursuant to subsection 5(c), and the outstanding Stock
Awards will be appropriately adjusted in the class(es) and number of securities
and price per share of Common Stock subject to such outstanding Stock Awards.
The Board shall make such adjustments, and its determination shall be final,
binding and conclusive. (The conversion of any convertible securities of the
Company shall not be treated as a transaction "without receipt of consideration"
by the Company.)

     (b) CHANGE IN CONTROL--DISSOLUTION OR LIQUIDATION. In the event of a
dissolution or liquidation of the Company, then all outstanding Stock Awards
shall terminate immediately prior to such event.

     (c) CHANGE IN CONTROL--ASSET SALE, MERGER, CONSOLIDATION OR REVERSE MERGER.
In the event of (i) a sale, lease or other disposition of all or substantially
all of the assets of the Company, (ii) a merger or consolidation in which the
Company is not the surviving corporation or (iii) a reverse merger in which the
Company is the surviving corporation but the shares of Common Stock outstanding
immediately preceding the merger are converted by virtue of the merger into
other property, whether in the form of securities, cash or otherwise, then any
surviving corporation or acquiring corporation shall assume any Stock Awards
outstanding under the Plan or shall substitute similar stock awards (including
an award to acquire the same consideration paid to the stockholders in the
transaction described in this subsection 11(c)) for those outstanding under the
Plan. In the event any surviving corporation or acquiring corporation refuses to
assume such Stock Awards or to substitute similar stock awards for those
outstanding under the Plan, then with respect to Stock Awards held by
Participants whose Continuous Service has not terminated, the vesting of such
Stock Awards (and, if applicable, the time during which such Stock Awards may be
exercised) shall be accelerated in full, and the 


                                       17
<PAGE>   18

Stock Awards shall terminate if not exercised (if applicable) at or prior to
such event. With respect to any other Stock Awards outstanding under the Plan,
such Stock Awards shall terminate if not exercised (if applicable) prior to such
event.

     (d) CHANGE IN CONTROL--SECURITIES ACQUISITION. After the Listing Date, in
the event of an acquisition by any person, entity or group within the meaning of
Section 13(d) or 14(d) of the Exchange Act, or any comparable successor
provisions (excluding any employee benefit plan, or related trust, sponsored or
maintained by the Company or an Affiliate) of the beneficial ownership (within
the meaning of Rule 13d-3 promulgated under the Exchange Act, or comparable
successor rule) of securities of the Company representing at least fifty percent
(50%) of the combined voting power entitled to vote in the election of
Directors, then any such acquiring person, entity or group shall assume any
Stock Awards outstanding under the Plan or shall substitute similar stock awards
(including an award to acquire the same consideration paid to the stockholders
in the transaction described in this subsection 11(d)) for those outstanding
under the Plan. In the event any such acquiring person, entity or group refuses
to assume such Stock Awards or to substitute similar stock awards for those
outstanding under the Plan, then with respect to Stock Awards held by
Participants whose Continuous Service has not terminated, the vesting of such
Stock Awards (and, if applicable, the time during which such Stock Awards may be
exercised) shall be accelerated in full, and the Stock Awards shall terminate if
not exercised (if applicable) at or prior to such event. With respect to any
other Stock Awards outstanding under the Plan, such Stock Awards shall terminate
if not exercised (if applicable) prior to such event.

     (e) CHANGE IN CONTROL--CHANGE IN INCUMBENT BOARD. After the Listing Date,
in the event that the individuals who, as of the Listing Date, are members of
the Board (the "Incumbent Board"), cease for any reason to constitute at least
fifty percent (50%) of the Board, then with respect to Stock Awards held by
persons whose Continuous Service has not terminated, the vesting of such Stock
Awards (and, if applicable, the time during which such Stock Awards may be
exercised) shall be accelerated in full. If the election, or nomination for
election, by the Company's stockholders of any new Director was approved by a
vote of at least fifty percent (50%) of the Incumbent Board, such new Director
shall be considered as a member of the Incumbent Board.

12.  AMENDMENT OF THE PLAN AND STOCK AWARDS.

     (a) AMENDMENT OF PLAN. The Board at any time, and from time to time, may
amend the Plan. However, except as provided in Section 11 relating to
adjustments upon changes in Common Stock, no amendment shall be effective unless
approved by the stockholders of the Company to the extent stockholder approval
is necessary to satisfy the requirements of Section 422 of the Code, Rule 16b-3
or any Nasdaq or securities exchange listing requirements.

     (b) STOCKHOLDER APPROVAL. The Board may, in its sole discretion, submit any
other amendment to the Plan for stockholder approval, including, but not limited
to, amendments to the Plan intended to satisfy the requirements of Section
162(m) of the Code and the regulations thereunder regarding the exclusion of
performance-based compensation from the limit on corporate deductibility of
compensation paid to certain executive officers.



                                       18
<PAGE>   19

     (c) CONTEMPLATED AMENDMENTS. It is expressly contemplated that the Board
may amend the Plan in any respect the Board deems necessary or advisable to
provide eligible Employees with the maximum benefits provided or to be provided
under the provisions of the Code and the regulations promulgated thereunder
relating to Incentive Stock Options and/or to bring the Plan and/or Incentive
Stock Options granted under it into compliance therewith.

     (d) NO IMPAIRMENT OF RIGHTS. Rights under any Stock Award granted before
amendment of the Plan shall not be impaired by any amendment of the Plan unless
(i) the Company requests the consent of the Participant and (ii) the Participant
consents in writing.

     (e) AMENDMENT OF STOCK AWARDS. The Board at any time, and from time to
time, may amend the terms of any one or more Stock Awards; provided, however,
that the rights under any Stock Award shall not be impaired by any such
amendment unless (i) the Company requests the consent of the Participant and
(ii) the Participant consents in writing.

13.  TERMINATION OR SUSPENSION OF THE PLAN.

     (a) PLAN TERM. The Board may suspend or terminate the Plan at any time.
Unless sooner terminated, the Plan shall terminate on the day before the tenth
(10th) anniversary of the date the Plan is adopted by the Board or approved by
the stockholders of the Company, whichever is earlier. No Stock Awards may be
granted under the Plan while the Plan is suspended or after it is terminated.

     (b) NO IMPAIRMENT OF RIGHTS. Suspension or termination of the Plan shall
not impair rights and obligations under any Stock Award granted while the Plan
is in effect except with the written consent of the Participant.

14.  EFFECTIVE DATE OF PLAN.

     The Plan shall become effective as determined by the Board, but no Stock
Award shall be exercised (or, in the case of a stock bonus, shall be granted)
unless and until the Plan has been approved by the stockholders of the Company,
which approval shall be within twelve (12) months before or after the date the
Plan is adopted by the Board.

15.  CHOICE OF LAW.

     The law of the State of Delaware shall govern all questions concerning the
construction, validity and interpretation of this Plan, without regard to such
state's conflict of laws rules.

                                  USA.NET, INC.

                        1999 EMPLOYEE STOCK PURCHASE PLAN

                             ADOPTED APRIL 1, 1999
              APPROVED BY THE STOCKHOLDERS ON _____________, 1999
             EFFECTIVE DATE: [DATE OF THE INITIAL PUBLIC OFFERING]


1.       PURPOSE.

         (a) The purpose of this 1999 Employee Stock Purchase Plan (the "Plan")
is to provide a means by which employees of USA.NET, Inc., a Delaware
corporation (the "Company"), and its Affiliates, as defined in subparagraph
1(b), which are designated as provided in subparagraph 2(b), may be given an
opportunity to purchase stock of the Company.

         (b) The word "Affiliate" as used in the Plan means any parent
corporation or subsidiary corporation of the Company, as those terms are defined
in Sections 424(e) and (f), respectively, of the Internal Revenue Code of 1986,
as amended (the "Code").

         (c) The Company, by means of the Plan, seeks to retain the services of
its employees, to secure and retain the services of new employees, and to
provide incentives for such persons to exert maximum efforts for the success of
the Company.

         (d) The Company intends that the rights to purchase stock of the
Company granted under the Plan be considered options issued under an "employee
stock purchase plan" as that term is defined in Section 423(b) of the Code.

2.       ADMINISTRATION.

         (a) The Plan shall be administered by the Board of Directors (the
"Board") of the Company unless and until the Board delegates administration to a
committee as provided in subparagraph 2(c). Whether or not the Board has
delegated administration the Board shall have the final power to determine all
questions of policy and expediency that may arise in the administration of the
Plan.

         (b) The Board shall have the power, subject to, and within the
limitations of, the express provisions of the Plan:

                  (i) To determine when and how rights to purchase stock of the
Company shall be granted and the provisions of each offering of such rights
(which need not be identical).

                  (ii) To designate from time to time which Affiliates of the
Company shall be eligible to participate in the Plan.

                  (iii) To construe and interpret the Plan and rights granted
under it, and to establish, amend and revoke rules and regulations for its
administration. The Board, in the


                                       1
<PAGE>   2

exercise of this power, may correct any defect, omission or inconsistency in the
Plan, in a manner and to the extent it shall deem necessary or expedient to make
the Plan fully effective.

                  (iv) To amend the Plan as provided in paragraph 13.

                  (v) Generally, to exercise such powers and to perform such
acts as the Board or the Committee deems necessary or expedient to promote the
best interests of the Company and its Affiliates and to carry out the intent
that the Plan be treated as an "employee stock purchase plan" within the meaning
of Section 423 of the Code.

         (c) The Board may delegate administration of the Plan to a committee
composed of not fewer than two (2) members of the Board (the "Committee"). If
administration is delegated to a Committee, the Committee shall have, in
connection with the administration of the Plan, the powers theretofore possessed
by the board, subject, however, to such resolutions, not inconsistent with the
provisions of the Plan, as may be adopted from time to time by the Board. The
Board may abolish the Committee at any time and revest in the Board the
administration of the Plan.

3.       SHARES SUBJECT TO THE PLAN.

         (a) Subject to the provisions of paragraph 12 relating to adjustments
upon changes in stock, the stock that may be sold pursuant to rights granted
under the Plan shall not exceed in the aggregate _____________ (________) shares
of the Company's common stock (the "Common Stock"). If any right granted under
the Plan shall for any reason terminate without having been exercised, the
Common Stock not purchased under such right shall again become available for the
Plan.

         (b) The stock subject to the Plan may be unissued shares or reacquired
shares, bought on the market or otherwise.

4.       GRANT OF RIGHTS; OFFERING.

         (a) The Board or the Committee may from time to time grant or provide
for the grant of rights to purchase Common Stock of the Company under the Plan
to eligible employees (an "Offering") on a date or dates (the "Offering
Date(s)") selected by the Board or the Committee. Each Offering shall be in such
form and shall contain such terms and conditions as the Board or the Committee
shall deem appropriate, which shall comply with the requirements of Section
423(b)(5) of the Code that all employees granted rights to purchase stock under
the Plan shall have the same rights and privileges. The terms and conditions of
an Offering shall be incorporated by reference into the Plan and treated as part
of the Plan. The provisions of separate Offerings need not be identical, but
each Offering shall include (through incorporation of the provisions of this
Plan by reference in the document comprising the Offering or otherwise) the
period during which the Offering shall be effective, which period shall not
exceed twenty-seven (27) months beginning with the Offering Date, and the
substance of the provisions contained in paragraphs 5 through 8, inclusive.




                                       2
<PAGE>   3

         (b) If an employee has more than one right outstanding under the Plan,
unless he or she otherwise indicates in agreements or notices delivered
hereunder: (1) each agreement or notice delivered by that employee will be
deemed to apply to all of his or her rights under the Plan, and (2) a right with
a lower exercise price (or an earlier-granted right, if two rights have
identical exercise prices), will be exercised to the fullest possible extent
before a right with a higher exercise price (or a later-granted right, if two
rights have identical exercise prices) will be exercised.

5.       ELIGIBILITY.

         (a) Rights may be granted only to employees of the Company or, as the
Board or the Committee may designate as provided in subparagraph 2(b), to
employees of any Affiliate of the Company. Except as provided in subparagraph
5(b), an employee of the Company or any Affiliate shall not be eligible to be
granted rights under the Plan unless, on the Offering Date, such employee has
been in the employ of the Company or any Affiliate for such continuous period
preceding such grant as the Board or the Committee may require, but in no event
shall the required period of continuous employment be equal to or greater than
two (2) years. In addition, unless otherwise determined by the Board or the
Committee and set forth in the terms of the applicable Offering, no employee of
the Company or any Affiliate shall be eligible to be granted rights under the
Plan unless, on the Offering Date, such employee's customary employment with the
Company or such Affiliate is for at least twenty (20) hours per week and at
least five (5) months per calendar year.

         (b) The Board or the Committee may provide that each person who, during
the course of an Offering, first becomes an eligible employee of the Company or
designated Affiliate will, on a date or dates specified in the Offering which
coincides with the day on which such person becomes an eligible employee or
occurs thereafter, receive a right under that Offering, which right shall
thereafter be deemed to be a part of that Offering. Such right shall have the
same characteristics as any rights originally granted under that Offering, as
described herein, except that:

                  (i) the date on which such right is granted shall be the
"Offering Date" of such right for all purposes, including determination of the
exercise price of such right;

                  (ii) the period of the Offering with respect to such right
shall begin on its Offering Date and end coincident with the end of such
Offering; and

                  (iii) the Board or the Committee may provide that if such
person first becomes an eligible employee within a specified period of time
before the end of the Offering, he or she will not receive any right under that
Offering.

         (c) No employee shall be eligible for the grant of any rights under the
Plan if, immediately after any such rights are granted, such employee owns stock
possessing five percent (5%) or more of the total combined voting power or value
of all classes of stock of the Company or of any Affiliate. For purposes of this
subparagraph 5(c), the rules of Section 424(d) of the Code shall apply in
determining the stock ownership of any employee, and stock which such



                                       3
<PAGE>   4

employee may purchase under all outstanding rights and options shall be treated
as stock owned by such employee.

         (d) An eligible employee may be granted rights under the Plan only if
such rights, together with any other rights granted under "employee stock
purchase plans" of the Company and any Affiliates, as specified by Section
423(b)(8) of the Code, do not permit such employee's rights to purchase stock of
the Company or any Affiliate to accrue at a rate which exceeds twenty-five
thousand dollars ($25,000) of fair market value of such stock (determined at the
time such rights are granted) for each calendar year in which such rights are
outstanding at any time.

         (e) Officers of the Company and any designated Affiliate shall be
eligible to participate in Offerings under the Plan, provided, however, that the
Board or the Committee may provide in an Offering that certain employees who are
highly compensated employees within the meaning of Section 423(b)(4)(D) of the
Code shall not be eligible to participate.

6.       RIGHTS; PURCHASE PRICE.

         (a) On each Offering Date, each eligible employee, pursuant to an
Offering made under the Plan, shall be granted the right to purchase up to the
number of shares of Common Stock of the Company purchasable with a percentage
designated by the Board or the Committee not exceeding fifteen percent (15%) of
such employee's Earnings (as defined by the Board for each Offering) during the
period which begins on the Offering Date (or such later date as the Board or the
Committee determines for a particular Offering) and ends on the date stated in
the Offering, which date shall be no later than the end of the Offering. The
Board or the Committee shall establish one or more dates during an Offering (the
"Purchase Date(s)") on which rights granted under the Plan shall be exercised
and purchases of Common Stock carried out in accordance with such Offering.

         (b) In connection with each Offering made under the Plan, the Board or
the Committee may specify a maximum number of shares that may be purchased by
any employee as well as a maximum aggregate number of shares that may be
purchased by all eligible employees pursuant to such Offering. In addition, in
connection with each Offering that contains more than one Purchase Date, the
Board or the Committee may specify a maximum aggregate number of shares which
may be purchased by all eligible employees on any given Purchase Date under the
Offering. If the aggregate purchase of shares upon exercise of rights granted
under the Offering would exceed any such maximum aggregate number, the Board or
the Committee shall make a pro rata allocation of the shares available in as
nearly a uniform manner as shall be practicable and as it shall deem to be
equitable.

         (c) The purchase price of stock acquired pursuant to rights granted
under the Plan shall be not less than the lesser of:

                  (i) an amount equal to eighty-five percent (85%) of the fair
market value of the stock on the Offering Date; or

                  (ii) an amount equal to eighty-five percent (85%) of the fair
market value of the stock on the Purchase Date.

7.       PARTICIPATION; WITHDRAWAL; TERMINATION.

         (a) An eligible employee may become a participant in the Plan pursuant
to an Offering by delivering a participation agreement to the Company within the
time specified in the Offering, in such form as the Company provides. Each such
agreement shall authorize payroll deductions of up to the maximum percentage
specified by the Board or the Committee of such employee's Earnings (as defined
by the Board for each Offering) during the Offering. The payroll deductions made
for each participant shall be credited to an account for such participant under
the Plan and shall be deposited with the general funds of the Company. A
participant may reduce (including to zero) or increase such payroll deductions,
and an eligible employee may begin such payroll deductions, after the beginning
of any Offering only as provided for in the Offering. A participant may make
additional payments into his or her account only if specifically provided for in
the Offering and only if the participant has not had the maximum amount withheld
during the Offering.

         (b) At any time during an Offering, a participant may terminate his or
her payroll deductions under the Plan and withdraw from the Offering by
delivering to the Company a notice of withdrawal in such form as the Company
provides. Such withdrawal may be elected at any time prior to the end of the
Offering except as provided by the Board or the Committee in the Offering. Upon
such withdrawal from the Offering by a participant, the Company shall distribute
to such participant all of his or her accumulated payroll deductions (reduced to
the extent, if any, such deductions have been used to acquire stock for the
participant) under the Offering, without interest, and such participant's right
to acquire Common Stock under that Offering shall be automatically terminated. A
participant's withdrawal from an Offering will have no effect upon such
participant's eligibility to participate in any other Offerings under the Plan
but such participant will be required to deliver a new participation agreement
in order to participate in subsequent Offerings under the Plan.

         (c) Rights granted pursuant to any Offering under the Plan shall
terminate immediately upon cessation of a participant's employment with the
Company and any designated Affiliate, for any reason, and the Company shall
distribute to such terminated employee all of his or her accumulated payroll
deductions (reduced to the extent, if any, such deductions have been used to
acquire stock for the terminated employee), under the Offering, without
interest.

         (d) Rights granted under the Plan shall not be transferable by a
participant other than by will or the laws of descent and distribution, or by a
beneficiary designation as provided in paragraph 14, and during a participant's
lifetime, shall be exercisable only by such participant.

8.       EXERCISE.

         (a) On each date specified therefor in the relevant Offering ("Purchase
Date"), each participant's accumulated payroll deductions and other additional
payments specifically provided for in the Offering (without any increase for
interest) will be applied to the purchase of whole shares of stock of the
Company, up to the maximum number of shares permitted pursuant to the terms of
the Plan and the applicable Offering, at the purchase price specified in the
Offering. Unless otherwise provided for in the applicable Offering, no
fractional shares shall be issued



                                       5
<PAGE>   6

upon the exercise of rights granted under the Plan. The amount, if any, of
accumulated payroll deductions remaining in each participant's account after the
purchase of shares which is less than the amount required to purchase one share
of stock on the final Purchase Date of an Offering shall be held in each such
participant's account for the purchase of shares under the next Offering under
the Plan, unless such participant withdraws from such next Offering, as provided
in subparagraph 7(b), or is no longer eligible to be granted rights under the
Plan, as provided in paragraph 5, in which case such amount shall be distributed
to the participant after such final Purchase Date, without interest. The amount,
if any, of accumulated payroll deductions remaining in any participant's account
after the purchase of shares which is equal to the amount required to purchase
whole shares of Common Stock on the final Purchase Date of an Offering shall be
distributed in full to the participant after such Purchase Date, without
interest.

         (b) No rights granted under the Plan may be exercised to any extent
unless the shares to be issued upon such exercise under the Plan (including
rights granted thereunder) are covered by an effective registration statement
pursuant to the Securities Act of 1933, as amended (the "Securities Act") and
the Plan is in material compliance with all applicable state, foreign and other
securities and other laws applicable to the Plan. If on a Purchase Date in any
Offering hereunder the Plan is not so registered or in such compliance, no
rights granted under the Plan or any Offering shall be exercised on such
Purchase Date, and the Purchase Date shall be delayed until the Plan is subject
to such an effective registration statement and such compliance, except that the
Purchase Date shall not be delayed more than twelve (12) months and the Purchase
Date shall in no event be more than twenty-seven (27) months from the Offering
Date. If on the Purchase Date of any Offering hereunder, as delayed to the
maximum extent permissible, the Plan is not registered and in such compliance,
no rights granted under the Plan or any Offering shall be exercised then all
payroll deductions accumulated during the Offering (reduced to the extent, if
any, such deductions have been used to acquire stock) shall be distributed to
the participants, without interest.

9.       COVENANTS OF THE COMPANY.

         (a) During the terms of the rights granted under the Plan, the Company
shall at all times make reasonable efforts to keep available the number of
shares of stock required to satisfy such rights, provided that this section
shall not require the Company to take any action that would result in adverse
tax, accounting or financial consequences to the Company.

         (b) The Company shall seek to obtain from each federal, state, foreign
or other regulatory commission or agency having jurisdiction over the Plan such
authority as may be required to issue and sell shares of stock upon exercise of
the rights granted under the Plan. If, after reasonable efforts, the Company is
unable to obtain from any such regulatory commission or agency the authority
which counsel for the Company deems necessary for the lawful issuance and sale
of stock under the Plan, the Company shall be relieved from any liability for
failure to issue and sell stock upon exercise of such rights unless and until
such authority is obtained.



                                       6
<PAGE>   7

10.      USE OF PROCEEDS FROM STOCK.

         Proceeds from the sale of stock to participants pursuant to rights
granted under the Plan shall constitute general funds of the Company.

11.      RIGHTS AS A STOCKHOLDER.

         A participant shall not be deemed to be the holder of, or to have any
of the rights of a holder with respect to, any shares subject to rights granted
under the Plan unless and until the participant's shares acquired upon exercise
of rights hereunder are recorded in the books of the Company (or its transfer
agent).

12.      ADJUSTMENTS UPON CHANGES IN STOCK.

         (a) If any change is made in the stock subject to the Plan, or subject
to any rights granted under the Plan (through merger, consolidation,
reorganization, recapitalization, stock dividend, dividend in property other
than cash, stock split, liquidating dividend, combination of shares, exchange of
shares, change in corporate structure or other transaction not involving the
receipt of consideration by the Company), the Plan and outstanding rights will
be appropriately adjusted in the class(es) and maximum number of shares subject
to the Plan and the class(es) and number of shares and price per share of stock
subject to outstanding rights. Such adjustments shall be made by the Board or
the Committee, the determination of which shall be final, binding and
conclusive. (The conversion of any convertible securities of the Company shall
not be treated as a "transaction not involving the receipt of consideration by
the Company.")

         (b) In the event of: (1) a dissolution or liquidation of the Company;
(2) a merger or consolidation in which the Company is not the surviving
corporation; (3) a reverse merger in which the Company is the surviving
corporation but the shares of Common Stock outstanding immediately preceding the
merger are converted by virtue of the merger into other property, whether in the
form of securities, cash or otherwise; or (4) the acquisition by any person,
entity or group within the meaning of Section 13(d) or 14(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), or any comparable
successor provisions (excluding any employee benefit plan, or related trust,
sponsored or maintained by the Company or any Affiliate of the Company) of the
beneficial ownership (within the meaning of Rule 13d-3 promulgated under the
Exchange Act, or comparable successor rule) of securities of the Company
representing at least fifty percent (50%) of the combined voting power entitled
to vote in the election of directors, then, as determined by the Board in its
sole discretion (i) any surviving or acquiring corporation may assume
outstanding rights or substitute similar rights for those under the Plan, (ii)
such rights may continue in full force and effect, or (iii) participants'
accumulated payroll deductions may be used to purchase Common Stock immediately
prior to the transaction described above and the participants' rights under the
ongoing Offering terminated.

13.      AMENDMENT OF THE PLAN.

         (a) The Board or the Committee at any time, and from time to time, may
amend the Plan. However, except as provided in paragraph 12 relating to
adjustments upon changes in stock, no amendment shall be effective unless
approved by the stockholders of the Company within twelve (12) months before or
after the adoption of the amendment if such amendment




                                       7
<PAGE>   8

requires stockholder approval in order for the Plan to obtain employee stock
purchase plan treatment under Section 423 of the Code or to comply with the
requirements of Rule 16b-3 promulgated under the Exchange Act.

         (b) The Board or the Committee may amend the Plan in any respect the
Board or the Committee deems necessary or advisable to provide eligible
employees with the maximum benefits provided or to be provided under the
provisions of the Code and the regulations promulgated thereunder relating to
employee stock purchase plans and/or to bring the Plan and/or rights granted
under it into compliance therewith.

         (c) Rights and obligations under any rights granted before amendment of
the Plan shall not be altered or impaired by any amendment of the Plan, except
with the consent of the person to whom such rights were granted, or except as
necessary to comply with any laws or governmental regulations, or except as
necessary to ensure that the Plan and/or rights granted under the Plan comply
with the requirements of Section 423 of the Code.

14.      DESIGNATION OF BENEFICIARY.

         (a) A participant may file a written designation of a beneficiary who
is to receive any shares and cash, if any, from the participant's account under
the Plan in the event of such participant's death subsequent to the end of an
Offering but prior to delivery to the participant of such shares and cash. In
addition, a participant may file a written designation of a beneficiary who is
to receive any cash from the participant's account under the Plan in the event
of such participant's death during an Offering.

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

15.      TERMINATION OR SUSPENSION OF THE PLAN.

         (a) The Board or the Committee in its discretion, may suspend or
terminate the Plan at any time. No rights may be granted under the Plan while
the Plan is suspended or after it is terminated.

         (b) Rights and obligations under any rights granted while the Plan is
in effect shall not be altered or impaired by suspension or termination of the
Plan, except as expressly provided in the Plan or with the consent of the
person to whom such rights were granted, or except as necessary to comply with
any laws or governmental regulation, or except as necessary to ensure that the
Plan and/or rights granted under the Plan comply with the requirements of
Section 423 of the Code.

16.      EFFECTIVE DATE OF PLAN.

         The Plan shall become effective upon the effective date of the initial
public offering of the Common Stock of the Company (the "Effective Date"), but
no rights granted under the Plan shall be exercised unless and until the Plan
has been approved by the stockholders of the Company within twelve (12) months
before or after the date the Plan is adopted by the Board, which date may be

                      EMPLOYEE STOCK PURCHASE PLAN OFFERING

                             ADOPTED APRIL 1, 1999



1.       GRANT; OFFERING DATE.

         (a) The Board of Directors of USA.NET, Inc. (the "Company"), pursuant
to the Company's 1999 Employee Stock Purchase Plan (the "Plan"), hereby
authorizes the grant of rights to purchase shares of the common stock of the
Company ("Common Stock") to all Eligible Employees (an "Offering"). Subject to
subsection 1(b) below, the first Offering shall begin on the effective date of
the initial public offering of the Company's Common Stock (the "Effective Date")
and shall end on June 30, 2000 (the "Initial Offering"). Thereafter, subject to
subsection 1(b) below, an Offering shall begin on July 1 every year, beginning
on July 1, 2000. An Offering shall end on the day prior to the first day of the
subsequent Offering. The first day of an Offering is that Offering's "Offering
Date." If an Offering Date would fall on a day during which the Company's Common
Stock is not actively traded, then the Offering Date shall be the next
subsequent day during which the Company's Common Stock is actively traded.

         (b) Prior to the commencement of any Offering, the Board of Directors
(or the Committee described in subparagraph 2(c) of the Plan, if any) may change
any or all terms of such Offering and any subsequent Offerings. The granting of
rights pursuant to each Offering hereunder shall occur on each respective
Offering Date unless, prior to such date (a) the Board of Directors (or such
Committee) determines that such Offering shall not occur, or (b) no shares
remain available for issuance under the Plan in connection with the Offering.

2.       ELIGIBLE EMPLOYEES.

         (a) All employees of the Company and each of its Affiliates (as defined
in the Plan) incorporated in the United States, shall be granted rights to
purchase Common Stock under each Offering on the Offering Date of such Offering,
provided that each such employee otherwise meets the employment requirements of
subparagraph 5(a) of the Plan (an "Eligible Employee"). Notwithstanding the
foregoing, the following employees shall not be Eligible Employees or be granted
rights under an Offering: (i) part-time or seasonal employees whose customary
employment is less than 20 hours per week or 5 months per calendar year or (ii)
5% stockholders (including ownership through unexercised options) described in
subparagraph 5(c) of the Plan.

         (b) Each person who first becomes an Eligible Employee during any
Offering will, on the first business day of the month of July or January during
the Offering, which coincides with the day on which such person becomes an
Eligible Employee or which occurs thereafter, receive a right under such
Offering, which right shall thereafter be deemed to be a part of the Offering.





                                       1
<PAGE>   11

Such right shall have the same characteristics as any rights originally granted
under the Offering except that:

                  (1) the date on which such right is granted shall be the
"Offering Date" of such right for all purposes, including determination of the
exercise price of such right; and

                  (2) the Offering for such right shall begin on its Offering
Date and end coincident with the end of the ongoing Offering.

3.       RIGHTS.

         (a) Subject to the limitations contained herein and in the Plan, on
each Offering Date each Eligible Employee shall be granted the right to purchase
the number of shares of Common Stock purchasable with up to fifteen percent
(15%) of such Eligible Employee's Earnings paid during such Offering after the
Eligible Employee first commences participation; provided, however, that no
employee may purchase Common Stock on a particular Purchase Date that would
result in more than fifteen percent (15%) of such employee's Earnings in the
period from the Offering Date to such Purchase Date having been applied to
purchase shares under all ongoing Offerings under the Plan and all other Company
plans intended to qualify as "employee stock purchase plans" under Section 423
of the Internal Revenue Code of 1986, as amended (the "Code"). For this
Offering, "Earnings" means the total compensation paid to an employee, including
all salary, wages (including amounts elected to be deferred by the employee,
that would otherwise have been paid, under any cash or deferred arrangement or
other deferred compensation program established by the Company), overtime pay,
commissions, bonuses, and other remuneration paid directly to the employee, but
excluding profit sharing, the cost of employee benefits paid for by the Company,
education or tuition reimbursements, imputed income arising under any Company
group insurance or benefit program, traveling expenses, business and moving
expense reimbursements, income received in connection with stock options,
contributions made by the Company under any employee benefit plan, and similar
items of compensation.

         (b) Notwithstanding the foregoing, the maximum number of shares of
Common Stock an Eligible Employee may purchase on a Purchase Date in an Offering
is such number of shares as has a fair market value (determined as of the
Offering Date for such Offering) equal to (x) $25,000 multiplied by the number
of calendar years in which the right under such Offering has been outstanding
any time, minus (y) the fair market value of any other shares of Common Stock
(determined as of the relevant Offering Date with respect to such shares) which,
for purposes of the limitation of Section 423(b)(8) of the Code, are attributed
to any of such calendar years in which the right is outstanding. The amount in
clause (y) of the previous sentence shall be determined in accordance with
regulations under Section 423(b)(8) of the Code based on (i) the number of
shares previously purchased with respect to such calendar years pursuant to such
Offering or any other Offering under the Plan, or pursuant to any other Company
plans intended to qualify as "employee stock purchase plans" under Section 423
of the Code, and (ii) the number of shares subject to other rights outstanding
on the Offering Date for such Offering pursuant to the Plan or any other such
Company plan.





                                       2
<PAGE>   12

         (c) The maximum aggregate number of shares available to be purchased by
all Eligible Employees under an Offering shall be the number of shares remaining
available under the Plan on the Offering Date. If the aggregate purchase of
shares of Common Stock upon exercise of rights granted under the Offering would
exceed the maximum aggregate number of shares available under either of the
limits set forth in this subsection 3(c), the Board shall make a pro rata
allocation of the shares available in a uniform and equitable manner.

4.       PURCHASE PRICE.

         The purchase price of the Common Stock under the Offering shall be the
lesser of eighty-five percent (85%) of the fair market value of the Common Stock
on the Offering Date or eighty-five percent (85%) of the fair market value of
the Common Stock on the Purchase Date, in each case rounded up to the nearest
whole cent per share. For the Initial Offering, the fair market value of the
Common Stock at the time when the Offering commences shall be the price per
share at which shares of Common Stock are first sold to the public in the
Company's initial public offering.

5.       PARTICIPATION.

         (a) Except as otherwise provided in this paragraph 5, an Eligible
Employee may elect to participate in an Offering only at the beginning of the
Offering; provided, however, that a person who first becomes an Eligible
Employee during an Offering may elect to participate at the Offering Date
applicable to such Eligible Employee in accordance with subparagraph 2(b). An
Eligible Employee shall become a participant in an Offering by delivering an
agreement authorizing payroll deductions. Such deductions may be in whole
percentages only, with a minimum percentage of one percent (1%) and maximum
percentage of fifteen percent (15%) of Earnings. A participant may not make
additional payments into his or her account. The agreement shall be made on such
enrollment form as the Company provides, and must be delivered to the Company
before the date of participation to be effective for such Offering, as
determined by the Company and communicated to Eligible Employees. As to the
Initial Offering, the time for filing an enrollment form and commencing
participation for individuals who are Eligible Employees on the Offering Date
for the Initial Offering shall be determined by the Company and communicated to
such Eligible Employees.

         (b) Generally, a participant may increase or reduce (including to zero)
his or her participation level only as of each July 1 or January 1 during any
Offering (except not during the ten (10) days immediately preceding a Purchase
Date. Any such change in participation shall be made by delivering a notice to
the Company or a designated Affiliate in such form and at such time as the
Company provides. Notwithstanding the foregoing, a participant may reduce his or
her participation level to zero once at any time during the twelve (12) month
period ending on a Purchase Date (except not during the ten (10) days
immediately preceding a Purchase Date). Additionally, a participant may withdraw
from an Offering and receive his or her accumulated payroll deductions from the
Offering (reduced to the extent, if any, such deductions have been used to
acquire Common Stock for the participant on any prior Purchase Dates), without
interest at any time prior to the end of the Offering, excluding only each ten
(10) day period immediately preceding a Purchase Date (or such shorter period of
time determined by the Company and




                                       3
<PAGE>   13

communicated to participants), by delivering a withdrawal notice to the Company
in such form as the Company provides. A participant who has withdrawn from an
Offering shall not be entitled to again participate in such Offering, but may
participate in other Offerings under the Plan by submitting a new participation
agreement in accordance with the terms thereof.

6.       PURCHASES.

         Subject to the limitations contained herein, on each Purchase Date,
each participant's accumulated payroll deductions (without any increase for
interest) shall be applied to the purchase of whole shares of Common Stock, up
to the maximum number of shares permitted under the Plan and the Offering.
"Purchase Date" shall be defined as the last day of each December and of each
June. (Notwithstanding the foregoing sentence, June 30, 1999 under the Initial
Offering shall not be a Purchase Date.) If a Purchase Date would not fall on a
day during which the Company's Common Stock is actively traded, then the
Purchase Date shall be the nearest prior day during which the Company's Common
Stock is actively traded.

7.       NOTICES AND AGREEMENTS.

         Any notices or agreements provided for in an Offering or the Plan shall
be given in writing, in a form provided by the Company, and unless specifically
provided for in the Plan or this Offering shall be deemed effectively given upon
receipt or, in the case of notices and agreements delivered by the Company, five
(5) days after deposit in the United States mail, postage prepaid.

8.       EXERCISE CONTINGENT ON STOCKHOLDER APPROVAL.

         The rights granted under an Offering are subject to the approval of the
Plan by the shareholders as required for the Plan to obtain treatment as a
tax-qualified employee stock purchase plan under Section 423 of the Code.

9.       OFFERING SUBJECT TO PLAN.

         Each Offering is subject to all the provisions of the Plan, and its
provisions are hereby made a part of the Offering, and is further subject to all
interpretations, amendments, rules and regulations which may from time to time
be promulgated and adopted pursuant to the Plan. In the event of any conflict
between the provisions of an Offering and those of the Plan (including
interpretations, amendments, rules and regulations which may from time to time
be promulgated and adopted pursuant to the Plan), the provisions of the Plan
shall control.

("Series D Stock") (the "Additional Investors") set forth on Exhibit A hereto.
The Prior Investors and the Additional Investors shall collectively be referred
to hereinafter as the "Investors" and each individually as an "Investor."

                                    RECITALS

         WHEREAS, the Company and the Prior Investors entered into an Amended

SECTION 2.     REGISTRATION; RESTRICTIONS ON TRANSFER

         2.1   RESTRICTIONS ON TRANSFER.

               (a) Each Holder agrees not to make any disposition of all or any
portion of the Shares or Registrable Securities unless and until:

                   (i)  There is then in effect a registration statement under 
the Securities Act covering such proposed disposition and such disposition is
made in accordance with such registration statement; or

                   (ii) (A) The transferee has agreed in writing to be bound by
the terms of this Agreement, (B) such Holder shall have notified the Company of
the proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (C) if
reasonably requested by the Company, such Holder shall have furnished the
Company with an opinion of counsel, reasonably satisfactory to the Company, that
such disposition will not require registration of such shares under the
Securities Act. It is agreed that the Company will not require opinions of
counsel for transactions made pursuant to Rule 144 except in unusual
circumstances.

                   (iii) Notwithstanding the provisions of paragraphs (i) and 
(ii) above, no such registration statement or opinion of counsel shall be
necessary for a transfer by a Holder which is (A) a partnership to its partners
or former partners in accordance with partnership interests, (B) a corporation
to its stockholders in accordance with their interest in the corporation, (C) a
limited liability company to its members or former members in accordance with
their interest in the limited liability company, or (D) to the Holder's family
member or trust for the benefit of an individual Holder; provided that in each
case the transferee will be subject to the terms of this Agreement to the same
extent as if he were an original Holder hereunder.

               (b) Each certificate representing Shares or Registrable 
Securities shall (unless otherwise permitted by the provisions of the Agreement)
be stamped or otherwise imprinted with a legend substantially similar to the
following (in addition to any legend required under applicable state securities
laws or as provided elsewhere in this Agreement):

         THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED, SOLD OR
         OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND
         UNTIL REGISTERED UNDER THE ACT OR UNLESS THE COMPANY HAS RECEIVED AN
         OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT
         SUCH REGISTRATION IS NOT REQUIRED.

               (c) The Company shall be obligated to reissue promptly unlegended
certificates at the request of any holder thereof if the holder shall have
obtained an opinion of counsel (which counsel may be counsel to the Company)
reasonably acceptable to the Company 




                                       2.
<PAGE>   6

to the effect that the securities proposed to be disposed of may lawfully be so
disposed of without registration, qualification or legend.

               (d) Any legend endorsed on an instrument pursuant to applicable
state securities laws and the stop-transfer instructions with respect to such
securities shall be removed upon receipt by the Company of an order of the
appropriate blue sky authority authorizing such removal.

         2.2   DEMAND REGISTRATION.

               (a) Subject to the conditions of this Section 2.2, if the Company
shall receive a written request from the Holders of more than fifty percent
(50%) of the Registrable Securities then outstanding (the "Initiating Holders")
that the Company file a registration statement under the Securities Act covering
the registration of Registrable Securities having an aggregate offering price to
the public in excess of Ten Million Dollars ($10,000,000), then the Company
shall, within thirty (30) days of the receipt thereof, give written notice of
such request to all Holders, and subject to the limitations of this Section 2.2,
use its best efforts to effect, as soon as practicable, the registration under
the Securities Act of all Registrable Securities that the Holders request to be
registered.

               (b) If the Initiating Holders intend to distribute the
Registrable Securities covered by their request by means of an underwriting,
they shall so advise the Company as a part of their request made pursuant to
this Section 2.2 or any request pursuant to Section 2.4 and the Company shall
include such information in the written notice referred to in Section 2.2(a) or
Section 2.4(a), as applicable. In such event, the right of any Holder to include
its Registrable Securities in such registration shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting (unless otherwise mutually agreed by
a majority in interest of the Initiating Holders and such Holder) to the extent
provided herein. All Holders proposing to distribute their securities through
such underwriting shall enter into an underwriting agreement in customary form
with the underwriter or underwriters selected for such underwriting by a
majority in interest of the Initiating Holders (which underwriter or
underwriters shall be reasonably acceptable to the Company). Notwithstanding any
other provision of this Section 2.2 or Section 2.4, if the underwriter advises
the Company that marketing factors require a limitation of the number of
securities to be underwritten (including Registrable Securities) then the
Company shall so advise all Holders of Registrable Securities which would
otherwise be underwritten pursuant hereto, and the number of shares that may be
included in the underwriting shall be allocated to the Holders of such
Registrable Securities on a pro rata basis based on the number of Registrable
Securities held by all such Holders (including the Initiating Holders). Any
Registrable Securities excluded or withdrawn from such underwriting shall be
withdrawn from the registration.



                                       3.
<PAGE>   7

               (c) The Company shall not be required to effect a registration
pursuant to this Section 2.2:

                   (i) prior to the earlier of (A) October 17, 2002 and (B) the
date one hundred eighty (180) days following the closing of the Initial
Offering; or

                   (ii) after the Company has effected two (2) registrations
pursuant to this Section 2.2, and such registrations have been declared or
ordered effective, provided that no registration shall be deemed to be effective
unless at least seventy percent (70%) of the Registrable Securities requested to
be registered by the persons exercising such demand right are included in such
registration; or

                   (iii) during the period starting with the date of filing of,
and ending on the date one hundred eighty (180) days following the effective
date of the registration statement pertaining to the Initial Offering; provided
that the Company makes reasonable good faith efforts to cause such registration
statement to become effective;

                   (iv) if within thirty (30) days of receipt of a written
request from Initiating Holders pursuant to Section 2.2(a), the Company gives
notice to the Holders of the Company's intention to make its Initial Offering
within ninety (90) days; or

                   (v) if the Company shall furnish to Holders requesting a
registration statement pursuant to this Section 2.2, a certificate signed by the
Chairman of the Board stating that in the good faith judgment of the Board of
Directors of the Company, it would be seriously detrimental to the Company and
its stockholders for such registration statement to be effected at such time, in
which event the Company shall have the right to defer such filing for a period
of not more than one hundred twenty (120) days after receipt of the request of
the Initiating Holders; provided that such right to delay a request shall be
exercised by the Company not more than once in any twelve (12) month period.

           2.3 PIGGYBACK REGISTRATIONS. The Company shall notify all Holders of
Registrable Securities in writing at least thirty (30) days prior to the filing
of any registration statement under the Securities Act for purposes of a public
offering of securities of the Company (including, but not limited to,
registration statements relating to secondary offerings of securities of the
Company, but excluding registration statements relating to employee benefit
plans or with respect to corporate reorganizations or other transactions under
Rule 145 of the Securities Act) and will afford each such Holder an opportunity
to include in such registration statement all or part of such Registrable
Securities held by such Holder. Each Holder desiring to include in any such
registration statement all or any part of the Registrable Securities held by it
shall, within fifteen (15) days after the above-described notice from the
Company, so notify the Company in writing. Such notice shall state the intended
method of disposition of the Registrable Securities by such Holder. If a Holder
decides not to include all of its Registrable Securities in any registration
statement thereafter filed by the Company, such Holder shall nevertheless
continue to have the right to include any Registrable Securities in any
subsequent registration statement or 




                                       4.
<PAGE>   8

registration statements as may be filed by the Company with respect to offerings
of its securities, all upon the terms and conditions set forth herein.

               (a) UNDERWRITING. If the registration statement under which the
Company gives notice under this Section 2.3 is for an underwritten offering, the
Company shall so advise the Holders of Registrable Securities. In such event,
the right of any such Holder to be included in a registration pursuant to this
Section 2.3 shall be conditioned upon such Holder's participation in such
underwriting and the inclusion of such Holder's Registrable Securities in the
underwriting to the extent provided herein. All Holders proposing to distribute
their Registrable Securities through such underwriting shall enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by the Company. Notwithstanding any other
provision of the Agreement, if the underwriter determines in good faith that
marketing factors require a limitation of the number of shares to be
underwritten, the number of shares that may be included in the underwriting
shall be allocated, first, to the Company; second, to the Holders on a pro rata
basis based on the total number of Registrable Securities held by the Holders;
and third, to any stockholder of the Company (other than a Holder) on a pro rata
basis. No such reduction shall (i) reduce the securities being offered by the
Company for its own account to be included in the registration and underwriting,
or (ii) reduce the amount of securities of the selling Holders included in the
registration below twenty-five percent (25%) of the total amount of securities
included in such registration, unless such offering is the Initial Offering and
such registration does not include shares of any other selling stockholders, in
which event any or all of the Registrable Securities of the Holders may be
excluded in accordance with the immediately preceding sentence. In no event will
shares of any other selling stockholder be included in such registration which
would reduce the number of shares which may be included by Holders without the
written consent of Holders of not less than two-thirds (66 2/3%) of the
Registrable Securities proposed to be sold in the offering.

               (b) RIGHT TO TERMINATE REGISTRATION. The Company shall have the
right to terminate or withdraw any registration initiated by it under this
Section 2.3 prior to the effectiveness of such registration whether or not any
Holder has elected to include securities in such registration. The Registration
Expenses of such withdrawn registration shall be borne by the Company in
accordance with Section 2.5 hereof.

           2.4 FORM S-3 REGISTRATION. In case the Company shall receive from any
Holder or Holders of Registrable Securities a written request or requests that
the Company effect a registration on Form S-3 (or any successor to Form S-3) or
any similar short-form registration statement and any related qualification or
compliance with respect to all or a part of the Registrable Securities owned by
such Holder or Holders, the Company will:

               (a) promptly give written notice of the proposed registration,
and any related qualification or compliance, to all other Holders of Registrable
Securities; and

               (b) as soon as practicable, effect such registration and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of such Holder's or
Holders' Registrable Securities as are 




                                       5.
<PAGE>   9

specified in such request, together with all or such portion of the Registrable
Securities of any other Holder or Holders joining in such request as are
specified in a written request given within fifteen (15) days after receipt of
such written notice from the Company; provided, however, that the Company shall
not be obligated to effect any such registration, qualification or compliance
pursuant to this Section 2.4:

                   (i) if Form S-3 (or any successor or similar form) is not
available for such offering by the Holders, or

                   (ii) if the Holders, together with the holders of any other
securities of the Company entitled to inclusion in such registration, propose to
sell Registrable Securities and such other securities (if any) at an aggregate
price to the public of less than Five Hundred Thousand Dollars ($500,000), or

                   (iii) if the Company shall furnish to the Holders a
certificate signed by the Chairman of the Board of Directors of the Company
stating that in the good faith judgment of the Board of Directors of the
Company, it would be seriously detrimental to the Company and its stockholders
for such Form S-3 Registration to be effected at such time, in which event the
Company shall have the right to defer the filing of the Form S-3 registration
statement for a period of not more than one hundred twenty (120) days after
receipt of the request of the Holder or Holders under this Section 2.4;
provided, that such right to delay a request shall be exercised by the Company
not more than once in any twelve (12) month period, or

                   (iv) if the Company has, within the six (6) month period
preceding the date of such request, already effected a registration on Form S-3
for the Holders pursuant to this Section 2.4, or

                   (v) in any particular jurisdiction in which the Company would
be required to qualify to do business or to execute a general consent to service
of process in effecting such registration, qualification or compliance.

               (c) Subject to the foregoing, the Company shall file a Form S-3
registration statement covering the Registrable Securities and other securities
so requested to be registered as soon as practicable after receipt of the
request or requests of the Holders.

           2.5 EXPENSES OF REGISTRATION. Except as specifically provided herein,
all Registration Expenses incurred in connection with any registration,
qualification or compliance pursuant to Section 2.2 or any registration under
Section 2.3 or Section 2.4 herein shall be borne by the Company. All Selling
Expenses incurred in connection with any registrations hereunder, shall be borne
by the holders of the securities so registered pro rata on the basis of the
number of shares so registered. The Company shall not, however, be required to
pay for expenses of any registration proceeding begun pursuant to Section 2.2 or
2.4, the request of which has been subsequently withdrawn by the Initiating
Holders unless (a) the withdrawal is based upon material adverse information
concerning the Company of which the Initiating Holders were not aware at the
time of such request or (b) the Holders of a majority of Registrable Securities
agree 




                                       6.
<PAGE>   10

to forfeit their right to one requested registration pursuant to Section 2.2, in
which event such right shall be forfeited by all Holders). If the Holders are
required to pay the Registration Expenses, such expenses shall be borne by the
holders of securities (including Registrable Securities) requesting such
registration in proportion to the number of shares for which registration was
requested. If the Company is required to pay the Registration Expenses of a
withdrawn offering pursuant to clause (a) above, then the Holders shall not
forfeit their rights pursuant to Section 2.2 or Section 2.4 to a demand
registration.

           2.6 OBLIGATIONS OF THE COMPANY. Whenever required to effect the
registration of any Registrable Securities, the Company shall, as expeditiously
as reasonably possible:

               (a) Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use all reasonable efforts to cause
such registration statement to become effective, and, upon the request of the
Holders of a majority of the Registrable Securities registered thereunder, keep
such registration statement effective for up to ninety (90) days or, if earlier,
until the Holder or Holders have completed the distribution related thereto.

               (b) Prepare and file with the SEC such amendments and supplements
to such registration statement and the prospectus used in connection with such
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 such
registration statement.

               (c) Furnish to the Holders such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Securities Act, and such other documents as they may reasonably request in order
to facilitate the disposition of Registrable Securities owned by them.

               (d) Use all reasonable efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders, provided that the Company shall not be required in connection therewith
or as a condition thereto to qualify to do business or to file a general consent
to service of process in any such states or jurisdictions.

               (e) In the event of any underwritten public offering, enter into
and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter(s) of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

               (f) Notify each Holder of Registrable Securities covered by such
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 such 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.



                                       7.
<PAGE>   11

               (g) Furnish, at the request of a majority of the Holders
participating in the registration, on the date that such Registrable Securities
are delivered to the underwriters for sale, if such securities are being sold
through underwriters, or, if such securities are not being sold through
underwriters, on the date that the registration statement with respect to such
securities becomes effective, (i) an opinion, dated as of such date, of the
counsel representing the Company for the purposes of such registration, in form
and substance as is customarily given to underwriters in an underwritten public
offering and reasonably satisfactory to a majority in interest of the Holders
requesting registration, addressed to the underwriters, if any, and to the
Holders requesting registration of Registrable Securities and (ii) a letter
dated as of such date, from the independent certified public accountants of the
Company, in form and substance as is customarily given by independent certified
public accountants to underwriters in an underwritten public offering and
reasonably satisfactory to a majority in interest of the Holders requesting
registration, addressed to the underwriters, if any, and if permitted by
applicable accounting standards, to the Holders requesting registration of
Registrable Securities.

           2.7 TERMINATION OF REGISTRATION RIGHTS. All registration rights
granted under this Section 2 shall terminate and be of no further force and
effect five (5) years after the date of the Qualified Public Offering. In
addition, a Holder's registration rights shall expire if (i) the Company has
completed its Initial Offering and is subject to the provisions of the Exchange
Act, (ii) such Holder (together with its affiliates, partners and former
partners) holds less than 1% of the Company's outstanding Common Stock (treating
all share of convertible Preferred Stock on an as converted basis) and (iii) all
Registrable Securities held by and issuable to such Holder (and its affiliates,
partners and former partners) may be sold under Rule 144 during any ninety (90)
day period.

           2.8 DELAY OF REGISTRATION; FURNISHING INFORMATION.

               (a) No Holder shall have any right to obtain or seek an
injunction restraining or otherwise delaying any such registration as the result
of any controversy that might arise with respect to the interpretation or
implementation of this Section 2.

               (b) It shall be a condition precedent to the obligations of the
Company to take any action pursuant to Section 2.2, 2.3 or 2.4 that the selling
Holders shall furnish to the Company such information regarding themselves, the
Registrable Securities held by them and the intended method of disposition of
such securities as shall be required to effect the registration of their
Registrable Securities.

               (c) The Company shall have no obligation with respect to any
registration requested pursuant to Section 2.2 or Section 2.4 if, due to the
operation of subsection 2.2(b), the number of shares or the anticipated
aggregate offering price of the Registrable Securities to be included in the
registration does not equal or exceed the number of shares or the anticipated
aggregate offering price required to originally trigger the Company's obligation
to initiate such registration as specified in Section 2.2 or Section 2.4,
whichever is applicable.

           2.9 INDEMNIFICATION. In the event any Registrable Securities are
included in a registration statement under Sections 2.2, 2.3 or 2.4:

               (a) To the extent permitted by law, the Company will indemnify
and hold harmless each Holder, the partners, officers, directors and legal
counsel of each Holder, any underwriter (as defined in the Securities Act) for
such Holder and each person, if any, who controls such Holder or underwriter
within the meaning of the Securities Act or the Exchange Act, against any
losses, claims, damages, or liabilities (joint or several) to which they may
become subject under the Securities Act, the Exchange Act or other federal or
state law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively a "Violation") by the Company: (i) any
untrue statement or alleged untrue statement of a material fact contained in
such registration statement, including any preliminary prospectus or final
prospectus contained therein or any amendments or supplements thereto, (ii) the
omission or alleged omission to state therein a material fact required to be
stated therein, or necessary to make the statements therein not misleading, or
(iii) any violation or alleged violation by the Company of the Securities Act,
the Exchange Act, any state securities law or any rule or regulation promulgated
under the Securities Act, the Exchange Act or any state securities law in
connection with the offering covered by such registration statement; and the
Company will reimburse each such Holder, partner, officer or director,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action; provided however, that the indemnity
agreement contained in this Section 2.9(a) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Company, which consent shall
not be unreasonably withheld, nor shall the Company be liable in any such case
for any such loss, claim, damage, liability or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by such Holder, partner, officer, director, underwriter
or controlling person of such Holder.

               (b) To the extent permitted by law, each Holder will, if
Registrable Securities held by such Holder are included in the securities as to
which such registration qualifications or compliance is being effected,
indemnify and hold harmless the Company, each of its directors, its officers,
and legal counsel and each person, if any, who controls the Company within the
meaning of the Securities Act, any underwriter and any other Holder selling
securities under such registration statement or any of such other Holder's
partners, directors or officers or any person who controls such Holder, against
any losses, claims, damages or liabilities (joint or several) to which the
Company or any such director, officer, controlling person, underwriter or other
such Holder, or partner, director, officer or controlling person of such other
Holder may become subject under the Securities Act, the Exchange Act or other
federal or state law, insofar as such losses, claims, damages or liabilities (or
actions in respect thereto) arise out of or are based upon any Violation, in
each case to the extent (and only to the extent) that such Violation occurs in
reliance upon and in conformity with written information furnished by such
Holder under an instrument duly executed by such Holder and stated to be
specifically for use in connection with such registration; and each such Holder
will reimburse any legal or other expenses reasonably 





                                       9.
<PAGE>   13

incurred by the Company or any such director, officer, controlling person,
underwriter or other Holder, or partner, officer, director or controlling person
of such other Holder in connection with investigating or defending any such
loss, claim, damage, liability or action if it is judicially determined that
there was such a Violation; provided, however, that the indemnity agreement
contained in this Section 2.9(b) shall not apply to amounts paid in settlement
of any such loss, claim, damage, liability or action if such settlement is
effected without the consent of the Holder, which consent shall not be
unreasonably withheld; provided further, that in no event shall any indemnity
under this Section 2.9 exceed the gross proceeds from the offering received by
such Holder.

               (c) Promptly after receipt by an indemnified party under this
Section 2.9 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 2.9, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceeding. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if materially prejudicial to its ability to
defend such action, shall relieve such indemnifying party of any liability to
the indemnified party under this Section 2.9, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section 2.9.

               (d) If the indemnification provided for in this Section 2.9 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any losses, claims, damages or liabilities referred to
herein, the indemnifying party, in lieu of indemnifying such indemnified party
thereunder, shall to the extent permitted by applicable law contribute to the
amount paid or payable by such indemnified party as a result of such loss,
claim, damage or liability in such proportion as is appropriate to reflect the
relative fault of the indemnifying party on the one hand and of the indemnified
party on the other in connection with the Violation(s) that resulted in such
loss, claim, damage or liability, as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by a court of law by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission; provided, that in no event shall any contribution by a
Holder hereunder exceed the proceeds from the offering received by such Holder.

               (e) The obligations of the Company and Holders under this Section
2.9 shall survive completion of any offering of Registrable Securities in a
registration statement and the termination of this agreement. No Indemnifying
Party, in the defense of any such claim or litigation, shall, except with the
consent of each Indemnified Party, consent to entry of any judgment or enter
into any settlement which does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such Indemnified Party of a release from
all liability in respect to such claim or litigation.

          2.10 ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause the
Company to register Registrable Securities pursuant to this Section 2 may be
assigned by a Holder to a transferee or assignee of Registrable Securities which
(i) is a subsidiary, parent, general partner, limited partner, retired partner,
member or retired member of a Holder, (ii) is a Holder's family member or trust
for the benefit of an individual Holder, or (iii) acquires at least two hundred
fifty thousand (250,000) shares of Registrable Securities (as adjusted for stock
splits and combinations); provided, however, (A) the transferor shall, within
ten (10) days after such transfer, furnish to the Company 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 and (B) such transferee
shall agree to be subject to all restrictions set forth in this Agreement.

          2.11 AMENDMENT OF REGISTRATION RIGHTS. Any provision of this Section 2
may be amended and the observance thereof may be waived (either generally or in
a particular instance and either retroactively or prospectively), only with the
written consent of the Company and the Holders of at least seventy percent (70%)
of the Registrable Securities then outstanding. Any amendment or waiver effected
in accordance with this Section 2.11 shall be binding upon each Holder and the
Company. By acceptance of any benefits under this Section 2, Holders of
Registrable Securities hereby agree to be bound by the provisions hereunder.

          2.12 LIMITATION ON SUBSEQUENT REGISTRATION RIGHTS. After the date of
this Agreement, the Company shall not, without the prior written consent of the
Holders of at least seventy percent (70%) of the Registrable Securities then
outstanding, enter into any agreement with any holder or prospective holder of
any securities of the Company that would grant such holder registration rights
senior to those granted to the Holders hereunder.

          2.13 "MARKET STAND-OFF" AGREEMENT. Each Holder hereby agrees that such
Holder shall not sell or otherwise transfer or dispose of any Common Stock (or
other securities) of the Company held by such Holder (other than those included
in the registration) for a period specified by the representative of the
underwriters of Common Stock (or other securities) of the Company not to exceed
one hundred eighty (180) days following the effective date of a registration
statement of the Company filed under the Securities Act, provided that:

                   (i) such agreement shall apply only to the Company's Initial
Offering; and

                   (ii) all officers and directors of the Company and holders of
at least one percent (1%) of the Company's voting securities enter into similar
agreements.



                                      11.
<PAGE>   15

          Each Holder agrees to execute and deliver such other agreements as may
be reasonably requested by the Company or the underwriter which are consistent
with the foregoing or which are necessary to give further effect thereto. The
obligations described in this Section 2.13 shall not apply to a registration
relating solely to employee benefit plans on Form S-1 or Form S-8 or similar
forms that may be promulgated in the future, or a registration relating solely
to a Commission Rule 145 transaction on Form S-4 or similar forms that may be
promulgated in the future. The Company may impose stop-transfer instructions
with respect to the shares of Common Stock (or other securities) subject to the
foregoing restriction until the end of said one hundred eighty (180) day period.

          2.14 RULE 144 REPORTING. With a view to making available to the
Holders the benefits of certain rules and regulations of the SEC which may
permit the sale of the Registrable Securities to the public without
registration, the Company agrees to use its best efforts to:

               (a) Make and keep public information available, as those terms
are understood and defined in SEC Rule 144 or any similar or analogous rule
promulgated under the Securities Act, at all times after the effective date of
the first registration filed by the Company for an offering of its securities to

               (b) File with the SEC, in a timely manner, all reports and other
documents required of the Company under the Exchange Act;

               (c) So long as a Holder owns any Registrable Securities, furnish
to such Holder forthwith upon request: a written statement by the Company as to
its compliance with the reporting requirements of said Rule 144 of the
Securities Act, and of the Exchange Act (at any time after it has become subject
to such reporting requirements); a copy of the most recent annual or quarterly

reasonably request in availing itself of any rule or regulation of the SEC
allowing it to sell any such securities without registration.

(250,000) shares of Registrable Securities (as adjusted for stock splits and

Series A Stock, (ii) 87,800 shares of Series B Stock, (iii) 73,600 shares of

discuss the affairs, finances and accounts of the Company or any of its
subsidiaries with its officers, and to review such information as is reasonably
requested all at such reasonable times and as often as may be reasonably
requested; provided, however, that the Company shall not be obligated under this
Section 3.2 with respect to a competitor of the Company or with respect to
information which the Board of Directors determines in good faith is
confidential and should not, therefore, be disclosed.

           3.3 CONFIDENTIALITY OF RECORDS. Each Investor agrees to use, and to
use its best efforts to insure that its authorized representatives use, the same
degree of care as such Investor uses to protect its own confidential information
to keep confidential any information furnished to it which the Company
identifies as being confidential or proprietary (so long as such information is
not in the public domain), except that such Investor may disclose such
proprietary or 




                                      14.

(the "Purchase Agreement").

           3.6 SBIC COVENANTS.

               (a) The Company acknowledges that Philadelphia Ventures Liberty
Fund, L.P. (the "SBIC Investor") is a Federal licensee under the Small Business
Investment Act of 1958, as amended (the "Small Business Act"), and, as such, is
subject to regulation by the United States Small Business Administration (the
"SBA") as a small business investment company.

               (b) As a result of the SBIC Investor's status as Federal
licensee, the Company covenants and agrees that until May 13, 1999, the Company
shall not make a material change in its primary business activity by becoming
involved in real estate financing, project financing, farm land purchasing,
relender or reinvestor financing, foreign investment and other businesses as
described in 13 C.F.R. Section 107.720, which would make it ineligible for
financing as a portfolio company by a small business investment company under 13
C.F.R. Section 107.760(b), a regulation promulgated by the SBA. In the event
that the Company breaches the foregoing covenant, the Company agrees that,
subject to applicable law, the SBIC Investor shall not be required to retain its
investment in the Series C Stock as further set forth in 13 C.F.R. Section
107.760 and shall be authorized to return such shares in exchange for
reimbursement by the Company of the purchase price paid for such shares.

               (c) The Company covenants and agrees that proceeds from the SBIC
Investor from its purchase of Series C Preferred Stock will be used for working
capital purposes or to otherwise finance the growth, modernization or expansion
of the Company. The Company shall provide the SBIC Investor and the SBA
reasonable access to the Company's books and records for the purpose of
confirming the use of such proceeds.

               (d) The Company shall provide the SBIC Investor with sufficient
information to permit such Investor to comply with its obligations under the
Small Business Act, provided, however, that the SBIC Investor agrees that it
will protect any information which the Company labels as confidential to the
extent permitted by law. Until May 13, 2000, any submission of financial
information under Section 3.1 to the SBIC Investor shall be accompanied by a
certificate of the president, chief executive officer, treasurer or chief
financial officer, which certificate shall 




                                      15.
<PAGE>   19

state that the Company is not in material default under any of its covenants set
forth in this Section 3.

           3.7 NOTIFICATION OF CERTAIN EVENTS. The Company shall promptly notify
The American Express Travel Related Services Company, Inc. and all Major
Investors in writing of any material outstanding or threatened claim, suit,
investigation, proceeding or other process or any material order, judgment,
directive or restrictions against or involving the Company or the transactions
contemplated hereby.

           3.8 TERMINATION OF COVENANTS. All covenants of the Company contained
in Section 3 of this Agreement (other than Section 3.6) shall expire and
terminate as to each Investor on the effective date of the Qualified Public
Offering.

SECTION 4.     PREEMPTIVE RIGHTS

           4.1 SUBSEQUENT OFFERINGS. Each Investor shall have a preemptive right
to purchase its pro rata share of all Equity Securities, as defined below, that
the Company may, from time to time, propose to sell and issue after the date of
this Agreement, other than the Equity Securities excluded by Section 4.6 hereof.
Each Investor's pro rata share is equal to the ratio of (A) the number of shares
of the Company's Common Stock (including all shares of Common Stock issued or
issuable upon conversion of the Shares) of which such Investor is deemed to be a
holder immediately prior to the issuance of such Equity Securities to (B) the
total number of shares of the Company's outstanding Common Stock (including all
shares of Common Stock issued or issuable upon conversion of the Shares or upon
the exercise of any outstanding warrants or options) held by all Investors
immediately prior to the issuance of the Equity Securities. The term "Equity
Securities" shall mean (i) any Common Stock, Preferred Stock or other security
of the Company, (ii) any security convertible, with or without consideration,
into any Common Stock, Preferred Stock or other security (including any option
to purchase such a convertible security), (iii) any security carrying any
warrant or right to subscribe to or purchase any Common Stock, Preferred Stock
or other security or (iv) any such warrant or right.

           4.2 EXERCISE OF RIGHTS. If the Company proposes to issue any Equity
Securities, it shall give each Investor written notice of its intention,
describing the Equity Securities, the price and the terms and conditions upon
which the Company proposes to issue the same. Each Investor shall have fifteen
(15) days from the giving of such notice to agree to purchase its pro rata share
of the Equity Securities for the price and upon the terms and conditions
specified in the notice by giving written notice to the Company and stating
therein the quantity of Equity Securities to be purchased. Notwithstanding the
foregoing, the Company shall not be required to offer or sell such Equity
Securities to any Investor who would cause the Company to be in violation of
applicable federal securities laws by virtue of such offer or sale.

           4.3 ISSUANCE OF EQUITY SECURITIES TO OTHER PERSONS. If not all of the
Investors elect to purchase their pro rata share of the Equity Securities, then
the Company shall promptly notify in writing the Investors who do so elect and
shall offer such Investors the right to acquire such unsubscribed shares. The
Investors shall have five (5) days after receipt of such notice to notify 




                                      16.
<PAGE>   20

the Company of their election to purchase all or a portion thereof of the
unsubscribed shares. If such Investors fail to exercise in full the preemptive
rights, the Company shall have ninety (90) days thereafter to sell the Equity
Securities in respect of which the Investors' rights were not exercised, at a
price and upon general terms and conditions materially no more favorable to the
purchasers thereof than specified in the Company's notice to the Investors
pursuant to Section 4.2 hereof. If the Company has not sold such Equity
Securities within ninety (90) days of the notice provided pursuant to Section
4.2, the Company shall not thereafter issue or sell any Equity Securities,
without first offering such securities to the Investors in the manner provided
above.

           4.4 TERMINATION OF PREEMPTIVE RIGHTS. The preemptive rights
established by this Section 4 shall not apply to, and shall terminate upon the
effective date of the registration statement pertaining to the Qualified Public
Offering.

           4.5 TRANSFER OF PREEMPTIVE RIGHTS. The preemptive rights of each
Investor under this Section 4 may be transferred to the same parties set forth
in Section 2.10(i) and (ii), or to a transferee or assignee of Registrable
Securities which acquires at least two hundred fifty thousand (250,000) shares
of Registrable Securities (as adjusted for stock splits, combinations and the
like), subject to the same restrictions as any transfer of registration rights
pursuant to Section 2.10.

           4.6 EXCLUDED SECURITIES. The preemptive rights established by this
Section 4 shall have no application to any of the following Equity Securities:

               (a) shares of Series D Stock issued pursuant to Section 2.3 of
the Purchase Agreement;

               (b) shares of Common Stock (and/or options, warrants or other
Common Stock purchase rights issued pursuant to such options, warrants or other
rights) issued or to be issued to employees, officers or directors of, or
consultants or advisors to the Company or any subsidiary, pursuant to stock
purchase or stock option plans or other arrangements that are approved by the
Board of Directors (collectively, the "Option Shares"), provided that the number
of Option Shares issued pursuant to this clause (a) does not exceed twenty
percent (20%) of the total outstanding capital stock of the Company (assuming
conversion of all shares of Preferred Stock into Common Stock and assuming the
conversion or exercise of all options, warrants or other rights to purchase
capital stock of the Company, including the Option Shares issued);

               (c) stock issued pursuant to any rights or agreements outstanding
as of the date of this Agreement, options and warrants outstanding as of the
date of this Agreement; and stock issued pursuant to any such rights or
agreements granted after the date of this Agreement, provided that the
preemptive rights established by this Section 4 applied with respect to the
initial sale or grant by the Company of such rights or agreements;

               (d) any Equity Securities issued for consideration other than
cash pursuant to a merger, consolidation, acquisition or similar business
combination;



                                      17.
<PAGE>   21

               (e) shares of Common Stock issued in connection with any stock
split, stock dividend or recapitalization by the Company;

               (f) shares of Common Stock issued upon conversion of the Shares;

               (g) any Equity Securities issued pursuant to any equipment
leasing arrangement, or debt financing approved by the Board of Directors
(collectively the "Debt Financing Shares") from a bank or similar financial
institution which is not an affiliate of John Street; provided that the number
of Debt Financing Shares issued in all such transactions does not have an
aggregate value in excess of $250,000;

               (h) any Equity Securities that are issued by the Company pursuant
to a registration statement filed under the Securities Act; and

               (i) shares of the Company's Common Stock or Preferred Stock
issued in connection with strategic transactions involving the Company and other
entities, including (A) joint ventures, manufacturing, marketing or distribution
arrangements or (B) technology transfer or development arrangements; provided
that such strategic transactions and the issuance of shares therein, has been
approved by the Company's Board of Directors, including the representatives
designated by the holders of the Series A Stock, Series B Stock, Series C Stock
and Series D Stock.

SECTION 5.     RIGHTS OF FIRST OFFER AND CO-SALE RIGHTS

           5.1 DEFINITIONS. For purposes of this Section 5, the following
definitions shall apply:

               (a) "CO-SALE STOCK" shall mean shares of the Company's Common
Stock now owned or subsequently acquired by a Major Investor. The number of
shares of Common Stock owned by each Major Investor is set forth on Exhibit A,
which Exhibit shall be amended from time to time to reflect changes in the
number of shares owned by each Major Investor.

               (b) "COMMON STOCK" shall mean the Company's Common Stock and
shares of Common Stock issued or issuable upon conversion of the Company's
outstanding Preferred Stock.

           5.2 SALES BY MAJOR INVESTORS.

               (a) NOTICE REQUIREMENT. If any Major Investor proposes to sell or
transfer any shares of Co-Sale Stock then such Major Investor shall promptly
give written notice (the "Notice") simultaneously to the Company and to each of
the other Investors at least forty-five (45) days prior to the closing of such
sale or transfer. The Company shall provide such Major Investor with a list of
the addresses of the Investors for purposes of satisfying such notice
requirement. The Notice shall describe in reasonable detail the proposed sale or
transfer including, without limitation, the number of shares of Co-Sale Stock to
be sold or transferred, the nature of such sale or transfer, the consideration
to be paid, and the name and address of each prospective purchaser or
transferee. In the event that the sale or transfer is being made pursuant 




                                      18.
<PAGE>   22

to the provisions of Sections 5.3(a) hereof, the Notice shall state under which
section the sale or transfer is being made.

               (b) COMPANY'S RIGHT TO PURCHASE. For a period of fifteen (15)
days following receipt of any Notice described in Section 5.2(a), the Company
shall have the right to purchase all or a portion of the Co-Sale Stock subject
to such Notice on the same terms and conditions as set forth therein. The
Company's purchase right shall be exercised by written notice signed by an
officer of the Company and delivered to the selling Major Investor with a check
for payment for the Co-Sale Stock being purchased.

               (c) MAJOR INVESTORS' RIGHT TO PURCHASE. If the Company does not
purchase all of the Co-Sale Stock available pursuant to its rights under Section
5.2(b) within the period set forth therein, each non-selling Major Investor
shall then have the right, exercisable upon written notice to the selling Major
Investor within thirty (30) days of the date of the original Notice described in
Section 5.2(a), to purchase its pro rata share of the Co-Sale Stock subject to
the Notice (less shares purchased by the Company pursuant to Section 5.2(b)) on
the same terms and conditions.

                   (i) Each non-selling Major Investor may buy all or any part
of that number of shares equal to the product obtained by multiplying (x) the
aggregate number of shares of Co-Sale Stock covered by the Notice (less shares
purchased by the Company pursuant to Section 5.2(b)) by (y) a fraction the
numerator of which is the number of shares of Common Stock owned by the
non-selling Major Investor (on an as-if-converted basis) at the time of the sale
or transfer and the denominator of which is the total number of shares of Common
Stock owned by all of the non-selling Major Investors (on an as-if-converted
basis) at the time of the sale or transfer.

                   (ii) If not all of the non-selling Major Investors elect to
purchase their pro rata share of the Co-Sale Stock covered by the Notice as
provided in Section 5.2(c)(i) above, then the selling Major Investor shall
promptly notify the non-selling Major Investors who do so elect and shall offer
such non-selling Major Investors the right to acquire such unsubscribed shares.
The non-selling Major Investors who elect to participate shall have five (5)
days after receipt of such notice to notify the selling Major Investor of its
election to purchase all or a portion thereof of the unsubscribed shares.

               (d) INVESTORS' RIGHT TO PARTICIPATE IN THE SALE OF CO-SALE STOCK.
Should the non-selling Major Investors and/or the Company fail to exercise their
respective rights to purchase all of the shares of Co-Sale Stock described in
the Notice issued pursuant to Section 5.2(a) following the exercise or
expiration of the rights of purchase described in Sections 5.2(b) and 5.2(c),
then each Investor shall have the right, exercisable upon written notice to the
selling Major Investor within forty-five (45) days of the date of the original
Notice described in Section 5.2(a), to participate in such sale of Co-Sale Stock
on the same terms and conditions. Such notice shall indicate the number of
shares of Common Stock such Investor wishes to sell under his or her right to
participate. To the extent one or more of the Investors exercise such right of
participation in accordance with the terms and conditions set forth below, the
number of 





                                      19.
<PAGE>   23

shares of Co-Sale Stock that the selling Major Investor may sell in the
transaction shall be correspondingly reduced.

                   (i) Each Investor may sell all or any part of that number of
shares equal to the product obtained by multiplying (x) the aggregate number of
shares of Co-Sale Stock covered by the Notice (as reduced by any purchases
pursuant to Sections 5.2(b) or 5.2(c)) by (y) a fraction the numerator of which
is the number of shares of Common Stock owned by the Investor at the time of the
sale or transfer (on an as-if-converted basis) and the denominator of which is
the total number of shares of Common Stock owned by the selling Major Investor
and the Investors at the time of the sale or transfer (on an as-if-converted
basis).

                   (ii) Each Investor who elects to participate in the sale
pursuant to this Section 5.2(d) (a "Participant") shall effect its participation
in the sale by promptly delivering to the selling Major Investor for transfer to
the prospective purchaser one or more certificates, properly endorsed for
transfer, which represent:

                         (1) the type and number of shares of Common Stock which
such Participant elects to sell; or

                         (2) that number of shares of Preferred Stock which is
at such time convertible into the number of shares of Common Stock which such
Participant elects to sell; provided, however, that if the prospective purchaser
objects to the delivery of Preferred Stock in lieu of Common Stock, such
Participant shall convert such Preferred Stock into Common Stock and deliver
Common Stock as provided in this Section 5.2(d). The Company agrees to make any
such conversion concurrently with the actual transfer of such shares to the
purchaser.

                   (iii) The stock certificate or certificates that the
Participant delivers to the selling Major Investor pursuant to this Section
5.2(d) shall be transferred to the prospective purchaser in consummation of the
sale of the Common Stock pursuant to the terms and conditions specified in the
Notice, and the selling Major Investor shall concurrently therewith remit to
such Participant that portion of the sale proceeds to which such Participant is
entitled by reason of its participation in such sale. To the extent that any
prospective purchaser or purchasers prohibits such assignment or otherwise
refuses to purchase shares or other securities from a Participant exercising its
rights of co-sale hereunder, the selling Major Investor shall not sell to such
prospective purchaser or purchasers any Co-Sale Stock unless and until,
simultaneously with such sale, the selling Major Investor shall purchase such
shares or other securities from such Participant on the same terms and
conditions specified in the Notice.

                   (iv) The exercise or non-exercise of the rights of the
Participants hereunder to participate in one or more sales of Co-Sale Stock made
by a selling Major Investor shall not adversely affect their rights to
participate in subsequent sales of Co-Sale Stock subject to Section 5.2(a).



                                      20.
<PAGE>   24

               (e) SALE OF CO-SALE STOCK. Should any shares of Co-Sale Stock
remain for sale to a third-party following the exercise or expiration of the
rights of purchase described in Sections 5.2(b) and 5.2(c) and the rights of
co-sale described in Section 5.2(d), then the selling Major Investor may, not
later than seventy-five (75) days following delivery to the Company of the
Notice, enter into an agreement providing for the closing of the transfer of the
Co-Sale Stock covered by the Notice (less shares purchased pursuant to Sections
5.2(b) and 5.2(c)) within thirty (30) days of such agreement on terms and
conditions not more favorable to the transferor than those described in the
Notice. Any proposed transfer on terms and conditions more favorable than those
described in the Notice, as well as any subsequent proposed transfer of any of
the Co-Sale Stock by the selling Major Investor, shall again be subject to the
purchase rights of the Company and the Major Investors and the co-sale rights of
the Investors and shall require compliance by the selling Major Investor with
the procedures described in this Section 5.2.

           5.3 EXEMPT TRANSFERS.

               (a) Notwithstanding the foregoing, the purchase rights of the
Company and the Major Investors and the co-sale rights of the Investors shall
not apply to (i) any pledge of Co-Sale Stock made pursuant to a bona fide loan
transaction with a financial institution that creates a mere security interest,
(ii) any transfer to the ancestors, descendants, or significant other or spouse
or to trusts for the benefit of such persons or the Major Investor (so long as
the transferee is not a Major Investor), (iii) any transfer to a general
partner, limited partner, member or retired partner or member of the Major
Investor or (iv) any bona fide gift; provided that in the event of any pledge or
transfer made pursuant to one of the exemptions provided by clauses (i), (ii)
and (iii), (A) the selling Major Investor shall inform the Investors of such
pledge, transfer or gift prior to effecting it and (B) the pledgee, transferee
or donee shall furnish the Investors with a written agreement to be bound by and
comply with all provisions of Section 5.2. Such transferred Co-Sale Stock shall
remain "Co-Sale Stock" hereunder, and such pledgee, transferee or donee shall be
treated as an Investor for purposes of this Agreement.

               (b) Notwithstanding the foregoing, the provisions of Section 5.2
shall not apply to the sale of any Co-Sale Stock to the public pursuant to a
registration statement filed with, and declared effective by, the SEC under the
Securities Act.

               (c) This Section 5 is subject to, and shall in no manner limit
the right of the Company to repurchase securities from any Investor pursuant to
a stock restriction agreement or other agreement between the Company and such
Investor.

           5.4 PROHIBITED TRANSFERS.

               (a) In the event that any Major Investor (a "Violating Investor")
should sell any Co-Sale Stock in contravention of the purchase rights of the
Company and the Major Investors and the co-sale rights of the Investors under
this Agreement (a "Prohibited Transfer"), each Investor, in addition to such
other remedies as may be available at law, in equity or hereunder, shall have
the put option provided below, and such Violating Investor shall be bound by the
applicable provisions of such option.



                                      21.
<PAGE>   25

               (b) In the event of a Prohibited Transfer, each Investor shall
have the right to sell to the Violating Investor the type and number of shares
of Common Stock equal to the number of shares each Investor would have been
entitled to transfer to the purchaser under Section 5.2(d) hereof had the
Prohibited Transfer been effected pursuant to and in compliance with the terms
hereof. Such sale shall be made on the following terms and conditions:

                   (i) The price per share at which the shares are to be sold to
the Violating Investor shall be equal to the price per share paid by the
purchaser to such Violating Investor in the Prohibited Transfer. The Violating
Investor shall also reimburse each non-selling Investor for any and all fees and
expenses, including legal fees and expenses, incurred pursuant to the exercise
or the attempted exercise of the Investor's rights under Section 5.2.

                   (ii) Within ninety (90) days after the later of the dates on
which the non-selling Investor (a) received notice of the Prohibited Transfer or
(b) otherwise became aware of the Prohibited Transfer, each non-selling Investor
shall, if exercising the option created hereby, deliver to the Violating
Investor the certificate or certificates representing shares to be sold, each
certificate to be properly endorsed for transfer.

                   (iii) The Violating Investor shall, upon receipt of the
certificate or certificates for the shares to be sold by an Investor, pursuant
to this Section 5.4(b), pay the aggregate purchase price therefor and the amount
of reimbursable fees and expenses, as specified in Section 5.4(b)(i) , in cash
or by other means acceptable to the Investor.

                   (iv) Notwithstanding the foregoing, any attempt by any Major
Investor to transfer Co-Sale Stock in violation of Section 5.2 hereof shall be
voidable at the option of Investors holding more than two-thirds in interest of
the Common Stock held by all Investors (on an as-converted basis) if the
Investors do not elect to exercise the put option set forth in this Section 5.4,
and the Company agrees it will not effect such a transfer nor will it treat any
alleged transferee as the holder of such shares without the written consent of a
majority in interest of the Investors.

           5.5 LEGEND.

               (a) Each certificate representing shares of Co-Sale Stock now or
hereafter owned by each Major Investor or issued to any person in connection
with a transfer pursuant to Section 5.3 hereof shall be endorsed with the
following legend:

         "THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES
         REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND CONDITIONS
         OF A CERTAIN INVESTOR RIGHTS AGREEMENT BY AND BETWEEN THE INVESTOR, THE
         COMPANY AND CERTAIN HOLDERS OF STOCK OF THE COMPANY. COPIES OF SUCH
         AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE
         COMPANY."



                                      22.
<PAGE>   26

               (b) Each Major Investor agrees that the Company may instruct its
transfer agent to impose transfer restrictions on the shares represented by
certificates bearing the legend referred to in Section 5.5 above to enforce the
provisions of this Agreement and the Company agrees to promptly do so. The
legend shall be removed upon termination of this Agreement.

           5.6 TRANSFER OF RIGHTS. The purchase rights of each Major Investor
and the rights of co-sale of each Investor under this Section 5 may be
transferred to the same parties set forth in Section 2.10(i) and (ii), or to a
transferee or assignee of Registrable Securities which acquires at least two
hundred fifty thousand (250,000) shares of Registrable Securities (as adjusted
for stock splits, combinations and the like), subject to the same restrictions
as any transfer of registration rights pursuant to Section 2.10.

           5.7 TERMINATION OF RIGHTS. The purchase rights of the Major Investors
and the rights of co-sale of each Investor under this Section 5 shall not apply
to and shall terminate upon the Company's Initial Offering.

THESE SECURITIES HAVE BEEN ISSUED PURSUANT TO EXEMPTIONS FOR NONPUBLIC OFFERINGS
FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933, AS AMENDED
(THE "ACT"), AND APPLICABLE STATE SECURITIES LAWS, AND, ACCORDINGLY, THESE
SECURITIES MAY NOT BE RESOLD OR OTHERWISE DISPOSED OF UNLESS, IN THE OPINION OF
COUNSEL FOR OR SATISFACTORY TO THE ISSUER, REGISTRATION UNDER THE APPLICABLE
FEDERAL OR STATE SECURITIES LAWS IS NOT REQUIRED OR COMPLIANCE IS MADE WITH SUCH
REGISTRATION REQUIREMENTS.


              VOID AFTER 5:00 P.M. MOUNTAIN TIME ON AUGUST 12, 2003


                               WARRANT TO PURCHASE
                        45,994 SHARES OF COMMON STOCK OF


                                  USA.NET, INC.


         This is to certify that, FOR VALUE RECEIVED, BT ALEX. BROWN
INCORPORATED or its registered assigns pursuant to Section (d) hereof
("HOLDER"), is entitled to purchase, subject to the provisions of this Warrant,
from USA.NET, Inc., a Delaware corporation (the "COMPANY"), forty-five thousand
nine hundred ninety-four (45,994) fully paid, validly issued and nonassessable
shares (the "INITIAL WARRANT SHARES") of Common Stock, par value $.001 per
share, of the Company ("COMMON STOCK"), at the exercise price of $14.75 per
share (the "INITIAL EXERCISE PRICE") on or prior to 5:00 p.m. Mountain Time on
August 12, 2003 (the "EXPIRATION DATE"). The Initial Warrant Shares and the
Initial Exercise Price may be adjusted from time to time as hereinafter set
forth. The Initial Warrant Shares, as adjusted from time to time, are
hereinafter sometimes referred to as "WARRANT SHARES," and the Initial Exercise
Price, as adjusted from time to time, is hereinafter sometimes referred to as
the "EXERCISE PRICE."

         (a) EXERCISE OF WARRANT; NOTIFICATION OF EXPIRATION DATE OF WARRANT.
The Warrant may be exercised at any time or from time to time, on or prior to
the Expiration Date (the "EXPIRATION DATE"), provided, however, that if such day
is a day on which banking institutions in the State of Colorado are authorized
by law to close, then on the next succeeding day which shall not be such a day.
The Warrant may be exercised by presentation and surrender hereof to the Company
at its principal office, or at the office of its stock transfer agent, if any,
with the Purchase Form annexed hereto duly executed (with signature guaranteed
if required by the Company or its stock transfer agent) and accompanied by
payment of the Exercise Price for the number of Warrant Shares specified in such
form and any applicable taxes. The purchase price for any Warrant Shares
purchased pursuant to the exercise of this Warrant shall be paid in full upon
such exercise in cash or by certified or bank check or pursuant to a cashless
exercise procedure whereby the Warrant Shares issued upon exercise of this
Warrant will be sold with Holder receiving the difference between the Exercise
Price and the sale price, in cash, and the 


                                       1.
<PAGE>   2

Company receiving the Exercise Price for the Warrant Shares, in cash, or any
combination of the foregoing methods of paying the Exercise Price. In the
alternative, the Warrant may be exchanged for Warrant Shares as described in
Section (k). As soon as practicable after each such exercise of the Warrant, but
not later than five (5) business days from the date of such exercise, the
Company shall issue and deliver to the Holder a certificate or certificates for
the Warrant Shares issuable upon such exercise, registered in the name of the
Holder or the Holder's designee, except in the case of a cashless exercise. If
the Warrant should be exercised in part only, the Company shall, upon surrender
of the Warrant for cancellation, execute and deliver a new Warrant evidencing
the rights of the Holder thereof to purchase the balance of the Warrant Shares
purchasable thereunder. In the event of a cash exercise, upon receipt by the
Company of the Warrant at its office, or by the stock transfer agent of the
Company at its office, in proper form for exercise, together with the Exercise
Price thereof and taxes as aforesaid in cash or certified or bank check and the
investment letter described below, the Holder shall be deemed to be the holder
of record of the shares of Common Stock issuable upon such exercise,
notwithstanding that the stock transfer books of the Company shall then be
closed or that certificates representing such shares of Common Stock shall not
then be physically delivered to the Holder. In order to assure the availability
of an exemption from registration under the federal or applicable state
securities laws, the Company may condition the exercise of the Warrant upon the
Holder delivering to the Company an investment letter in a form reasonably
satisfactory to the Company. It is further understood that certificates for the
Warrant Shares, if any, to be issued upon exercise of the Warrant may contain a
restrictive legend in accordance with Section (j) hereof. Notwithstanding
anything herein to the contrary, the Company shall mail to the Holder, by
certified mail, return receipt requested, notice of the Expiration Date of the
Warrants, no later than sixty (60) days prior to the Expiration Date. In the
event the Company shall fail to send such required notice at the time and in the
manner set forth in the preceding sentence, the Expiration Date of the Warrants
shall be extended to a date sixty (60) days following the date that a written
notice of the Expiration Date of the Warrants is sent by the Company.

         (b) RESERVATION OF SHARES. The Company shall at all times reserve for
issuance and/or delivery upon exercise of this Warrant such number of shares of
its Common Stock as shall be required for issuance and delivery upon exercise of
the Warrants. If the Common Stock is or becomes listed on any national
securities exchange or the NASDAQ National Market System, the Company shall also
list such shares on such exchange subject to notice of issuance or maintain the
listing of its Common Stock on the NASDAQ system, as the case may be. The
Company will take all such action as may be necessary to assure that such shares
of Common Stock may be issued as provided herein without violation of any
applicable law or regulation, or of any requirement of any domestic securities
exchange upon which the Common Stock may be listed; provided, however, that the
Company shall not be required to effect a registration under Federal or State
securities laws with respect to such exercise.

         (c) FRACTIONAL SHARES. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of the Warrant. With respect
to any fraction of a share called for upon any exercise hereof, the Company
shall pay to the Holder an amount in cash equal to such fraction multiplied by
the effective Exercise Price.

         (d) EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT. The Warrant is
exchangeable, without expense, at the option of the Holder, upon presentation
and surrender hereof to the Company or at the office of its stock transfer
agent, if any, for other Warrants of different denominations entitling the
Holder thereof to purchase in the aggregate the same number of shares of Common
Stock purchasable hereunder. Subject to Section (j) hereof, the Holder may
transfer or assign the Warrant, in whole or in part and from time to time. Upon
surrender of this Warrant to the Company at its principal office or at the
office of its stock transfer agent, if any, with the Assignment Form annexed
hereto duly executed (with signature guaranteed, if required by the Company or
its stock transfer agent) and funds sufficient to pay any transfer tax, the
Company shall, without charge, execute and deliver a new Warrant in the name of
the assignee or assignees named in such instrument of assignment and this
Warrant shall promptly be cancelled. This Warrant may be divided by or combined
with other Warrants which carry the same rights upon presentation hereof at the
principal office of the Company or at the office of its stock transfer agent, if
any, together with a written notice specifying the names and denominations in
which new Warrants are to be issued and signed by the Holder hereof. The term
"WARRANT" as used herein includes any Warrants into which this Warrant may be
divided or exchanged. Upon receipt by the Company of evidence satisfactory to it
of the loss, theft, destruction or mutilation of this Warrant, and in the case
of loss, theft or destruction, of reasonably satisfactory indemnification, and
upon surrender and cancellation of this Warrant, if mutilated, the Company will
execute and deliver a new Warrant of like tenor, date and amount. Any such new
Warrant executed and delivered shall constitute an additional contractual
obligation on the part of the Company, whether or not the original Warrant shall
be at any time enforceable by anyone.

         (e) NO VOTING OR DIVIDEND RIGHTS; LIMITATION OF LIABILITY. Nothing
contained in this Warrant shall be construed as conferring upon the Holder
hereof the right to vote or to consent or to receive notice as a stockholder of
the Company or any other matters or any rights whatsoever as a stockholder of
the Company. No dividends or interest shall be payable or accrued in respect of
this Warrant or the interest represented hereby or the shares purchasable
hereunder until, and only to the extent that, this Warrant shall have been
exercised. No provisions hereof, in the absence of affirmative action by the
Holder to purchase shares of Common Stock, and no mere enumeration herein of the
rights or privileges of the Holder hereof, shall give rise to any liability of
such Holder for the Exercise Price or as a stockholder of the Company, whether
such liability is asserted by the Company or by its creditors.

         (f) ADJUSTMENT OF STOCK PURCHASE PRICE AND NUMBER OF SHARES. The
Exercise Price and the number of shares purchasable upon the exercise of this
Warrant shall be subject to adjustment from time to time upon the occurrence of
certain events described in this Section (f). Upon each adjustment of the
Exercise Price pursuant to this Section (f), the Holder of this Warrant shall
thereafter be entitled to purchase, at the Exercise Price resulting from such
adjustment, the number of shares obtained by multiplying the Exercise Price in
effect immediately prior to such adjustment by the number of shares purchasable
pursuant hereto immediately prior to such adjustment, and dividing the product
thereof by the Exercise Price resulting from such adjustment.

                  (i) SUBDIVISION OR COMBINATION OF STOCK. In case the Company
shall at any time subdivide its outstanding shares of Common Stock into a
greater number of shares, the Exercise Price in effect immediately prior to such
subdivision shall be proportionately reduced, and conversely, in case the
outstanding shares of Common Stock of the Company shall be combined into a
smaller number of shares, the Exercise Price in effect immediately prior to such
combination shall be proportionately increased.



                                       3.
<PAGE>   4

                  (ii) DIVIDENDS IN STOCK, OTHER STOCK, PROPERTY,
RECLASSIFICATION. If at any time or from time to time the holders of Common
Stock (or any shares of stock or other securities at the time receivable upon
the exercise of this Warrant) shall have received or become entitled to receive,
without payment therefor:

                           (1) Common Stock or any shares of stock or other
securities which are at any time directly or indirectly convertible into or
exchangeable for Common Stock, or any rights or options to subscribe for,
purchase or otherwise acquire any of the foregoing by way of dividend or other
distribution;

                           (2) any cash paid or payable otherwise than as a cash
dividend; or

                           (3) Common Stock or additional stock or other
securities or property (including cash) by way of spinoff, split-up,
reclassification, combination of shares or similar corporate rearrangement,
(other than shares of Common Stock issued as a stock split or adjustments in
respect of which shall be covered by the terms of (f)(i) above);

then and in each such case, the Holder hereof shall, upon the exercise of this
Warrant, be entitled to receive, in addition to the number of shares of Common
Stock receivable thereupon, and without payment of any additional consideration
therefor, the amount of stock and other securities and property (including cash
in the cases referred to in clauses (f)(ii)(2) and (f)(ii)(3) above) which such
Holder would hold on the date of such exercise had he been the holder of record
of such Common Stock as of the date on which holders of Common Stock received or
became entitled to receive such shares or all other additional stock and other
securities and property.

                  (iii) ADJUSTMENT FOR RECLASSIFICATION, EXCHANGE AND
SUBSTITUTION. If at any time or from time to time prior to the Expiration Date,
the Common Stock issuable upon the exercise of this Warrant is changed into the
same or a different number of shares of any class or classes of stock, whether
by recapitalization, reclassification or otherwise (other than an Organic Change
(as defined below) or a subdivision or combination of shares or stock dividend
or a reorganization, merger, consolidation or sale of assets provided for
elsewhere in this Section (f)), in any such event the Holder hereof shall, upon
the exercise of this Warrant, be entitled to receive the kind and amount of
stock and other securities and property the Holder would have received had it
exercised this Warrant immediately prior to such recapitalization,
reclassification or other change, all subject to further adjustment as provided
herein or with respect to such other securities or property by the terms
thereof.

                  (iv) SALE OF SHARES BELOW EXERCISE PRICE.

                           (1) If at any time or from time to time prior to the
Expiration Date, the Company issues or sells, or is deemed by the express
provisions of this subsection (f) to have issued or sold, Additional Shares of
Common Stock (as defined in subsection (f)(iv)(4) below), other than as a
dividend or other distribution on any class of stock as provided in Section
(f)(ii) above, and other than a subdivision or combination of shares of Common
Stock as provided in 





                                       4.
<PAGE>   5

Section (f)(i) above, for an Effective Price (as defined in subsection
(f)(iv)(4) below) less than the Exercise Price, then and in each such case, the
then existing Exercise Price shall be reduced, as of the opening of business on
the date of such issue or sale, to a price determined by multiplying the
Exercise Price then in effect by a fraction (i) the numerator of which shall be
(A) the number of shares of Common Stock deemed outstanding (as defined below)
immediately prior to such issue or sale, plus (B) the number of shares of Common
Stock which the aggregate consideration received (as defined in subsection
(f)(iv)(2)) by the Company for the total number of Additional Shares of Common
Stock so issued would purchase at the Exercise Price, and (ii) the denominator
of which shall be the number of shares of Common Stock deemed outstanding (as
defined below) immediately prior to such issue or sale plus the total number of
Additional Shares of Common Stock so issued. For the purposes of the preceding
sentence, the number of shares of Common Stock deemed to be outstanding as of a
given date shall be the sum of (A) the number of shares of Common Stock actually
outstanding, (B) the number of shares of Common Stock into which the then
outstanding shares of the Company's Preferred Stock could be converted if fully
converted on the day immediately preceding the given date, and (C) the number of
shares of Common Stock which could be obtained through the exercise or
conversion of all other rights, options and convertible securities outstanding
on the day immediately preceding the given date whether or not then exercisable.

                           (2) For the purpose of making any adjustment required
under this Section (f)(iv), the consideration received by the Company for any
issue or sale of securities shall (A) to the extent it consists of cash, be
computed at the net amount of cash received by the Company after deduction of
any underwriting or similar commissions, compensation or concessions paid or
allowed by the Company in connection with such issue or sale but without
deduction of any expenses payable by the Company, (B) to the extent it consists
of property other than cash, be computed at the fair value of that property as
determined in good faith by the Board of Directors, and (C) if Additional Shares
of Common Stock, Convertible Securities (as defined in subsection (f)(3)) or
rights or options to purchase either Additional Shares of Common Stock or
Convertible Securities are issued or sold together with other stock or
securities or other assets of the Company for a consideration which covers both,
be computed as the portion of the consideration so received that may be
reasonably determined in good faith by the Board of Directors to be allocable to
such Additional Shares of Common Stock, Convertible Securities or rights or
options.

                           (3) For the purpose of the adjustment required under
this Section (f)(iv), if the Company issues or sells any rights or options for
the purchase of, or stock or other securities convertible into, Additional
Shares of Common Stock (such convertible stock or securities being herein
referred to as "Convertible Securities") and if the Effective Price of such
Additional Shares of Common Stock is less than the Exercise Price, in each case
the Company shall be deemed to have issued at the time of the issuance of such
rights or options or Convertible Securities the maximum number of Additional
Shares of Common Stock issuable upon exercise or conversion thereof and to have
received as consideration for the issuance of such shares an amount equal to the
total amount of the consideration, if any, received by the Company for the
issuance of such rights or options or Convertible Securities, plus, in the case
of such rights or options, the minimum amounts of consideration, if any, payable
to the Company upon the exercise of such rights or options, plus, in the case of
Convertible Securities, the minimum amounts of consideration, if any, payable to
the Company (other than by cancellation 




                                       5.
<PAGE>   6

of liabilities or obligations evidenced by such Convertible Securities) upon the
conversion thereof; provided that, if in the case of Convertible Securities, the
minimum amounts of such consideration cannot be ascertained, but are a function
of antidilution or similar protective clauses, the Company shall be deemed to
have received the minimum amounts of consideration without reference to such
clauses; provided further that, if the minimum amount of consideration payable
to the Company upon the exercise or conversion of rights, options or Convertible
Securities is reduced over time or on the occurrence or non-occurrence of
specified events other than by reason of antidilution adjustments, the Effective
Price shall be recalculated using the figure to which such minimum amount of
consideration is reduced; provided further that, if the minimum amount of
consideration payable to the Company upon the exercise or conversion of such
rights, options or Convertible Securities is subsequently increased, the
Effective Price shall be again recalculated using the increased minimum amount
of consideration payable to the Company upon the exercise or conversion of such
rights, options or Convertible Securities. No further adjustment of the number
of shares of Common Stock the Holder is entitled to upon exercise of this
Warrant, as adjusted upon the issuance of such rights, options or Convertible
Securities, shall be made as a result of the actual issuance of Additional
Shares of Common Stock on the exercise of any such rights or options or the
conversion of any such Convertible Securities. If any such rights or options or
the conversion privilege represented by any such Convertible Securities shall
expire without having been exercised, the number of shares of Common Stock the
Holder is entitled to upon exercise of this Warrant shall be readjusted to the
number of shares the Holder would have been entitled to had an adjustment been
made on the basis that the only Additional Shares of Common Stock so issued were
the Additional Shares of Common Stock, if any, actually issued or sold on the
exercise of such rights or options or rights of conversion of such Convertible
Securities, and such Additional Shares of Common Stock, if any, were issued or
sold for the consideration actually received by the Company upon such exercise,
plus the consideration, if any, actually received by the Company for the
granting of all such rights or options, whether or not exercised, plus the
consideration received for issuing or selling the Convertible Securities
actually converted, plus the consideration, if any, actually received by the
Company (other than by cancellation of liabilities or obligations evidenced by
such Convertible Securities) on the conversion of such Convertible Securities.

                           (4) "Additional Shares of Common Stock" shall mean
all shares of Common Stock issued by the Company or deemed to be issued pursuant
to this Section (f)(iv), whether or not subsequently reacquired or retired by
the Company other than (1) shares of Common Stock issued upon conversion of the
Company's Preferred Stock; (2) shares of Common Stock and/or options, warrants
or other Common Stock purchase rights, and the Common Stock issued pursuant to
such options, warrants or other rights (as adjusted for any stock dividends,
combinations, splits, recapitalizations and the like) (collectively, the "Option
Shares") after the date hereof, to employees, officers or directors of, or
consultants or advisors to the Company or any subsidiary pursuant to stock
purchase or stock option plans or other arrangements that are approved by the
Board, provided that, the number of Option Shares issued pursuant to this clause
(2) does not exceed twenty percent (20%) of the total outstanding capital stock
of the Company (assuming conversion of all shares of Preferred Stock into Common
Stock and assuming the conversion or exercise of all options, warrants or other
rights to purchase capital stock of the Company, including the Option Shares
issued); (3) shares of Common Stock or Preferred Stock (and Common Stock issued
or issuable upon conversion of such Preferred Stock) issued pursuant to the
exercise of options, warrants or convertible securities outstanding 




                                       6.
<PAGE>   7

prior to the date hereof; (4) Common Stock or Convertible Securities issued for
consideration other than cash pursuant to a merger, consolidation, acquisition
or similar business combination and (5) Common Stock or Convertible Securities
issued pursuant to any equipment leasing arrangement, or debt financing approved
by the Board of Directors (collectively the "Debt Financing Shares") from a bank
or similar financial institution; provided that the number of Debt Financing
Shares issued in all such transactions does not have an aggregate value in
excess of $250,000. The "Effective Price" of Additional Shares of Common Stock
shall mean the quotient determined by dividing the total number of Additional
Shares of Common Stock issued or sold, or deemed to have been issued or sold by
the Company under this Section (f)(iv), into the aggregate consideration
received, or deemed to have been received by the Company for such issue under
this Section (f)(iv), for such Additional Shares of Common Stock.

         (g) OFFICER'S CERTIFICATE. Whenever the Exercise Price shall be
adjusted as required by the provisions of Section (f), the Company shall
forthwith file in the custody of its Secretary or an Assistant Secretary at its
principal office and with its stock transfer agent, if any, an officers
certificate showing the adjusted Exercise Price determined as herein provided,
setting forth in reasonable detail the facts requiring such adjustment,
including a statement of the number of additional shares of Common Stock, if
any, and such other facts as shall be necessary to show the reason for and the
manner of computing such adjustment. Each such officers certificate shall be
made available at all reasonable times for inspection by the Holder or any
holder of a Warrant executed and/or delivered pursuant to Section (a) or Section
(d), and the Company shall, forthwith after each such adjustment, mail, by
certified mail, a copy of such certificate to the Holder or any such holder.

         (h) NOTICES TO WARRANT HOLDERS. So long as this Warrant shall be
outstanding, (i) if the Company shall pay any dividend or make any distribution
upon the Common Stock, or (ii) if the Company shall offer to the holders of
Common Stock for subscription or purchase by them any shares of any class or any
other rights, or (iii) if any capital reorganization of the Company,
reclassification of the capital stock of the Company, consolidation or merger of
the Company with or into another corporation, sale or transfer of all or
substantially all of the property and assets of the Company to another
corporation, or voluntary or involuntary dissolution, liquidation or winding up
of the Company shall be effected, then in any such case, the Company shall cause
to be mailed by certified mail to the Holder or any holder of a Warrant executed
and/or delivered pursuant to Section (a) or Section (d), at least fifteen (15)
days prior to the date specified in (x) or (y) below, as the case may be, a
notice containing a brief description of the proposed action and stating the
date on which (x) a record is to be taken for the purpose of such dividend,
distribution or rights, or (y) such reclassification, reorganization,
consolidation, merger, conveyance, dissolution, liquidation or winding up is to
take place and the date, if any is to be fixed, as of which the holders of
Common Stock or other securities shall receive cash or other property
deliverable upon such reclassification, reorganization, consolidation, merger,
conveyance, dissolution, liquidation or winding up.

         (i) RECLASSIFICATION, REORGANIZATION, CONSOLIDATION, MERGER OR SALE. In
case of any reclassification or capital reorganization of outstanding shares of
Common Stock of the Company, or in case of any consolidation or merger of the
Company with or into another corporation (other than a merger with another
corporation in which merger the Company is the continuing corporation and which
does not result in any reclassification or capital reorganization 





                                       7.
<PAGE>   8

of outstanding shares of Common Stock of the class issuable upon exercise of
this Warrant) or in case of any sale or conveyance to another corporation of the
property of the Company as an entirety (an "ORGANIC CHANGE"), the Company shall,
as a condition precedent to such transaction, cause effective provisions to be
made so that the Holder or any holder of a Warrant executed and/or delivered
pursuant to Section (a) or Section (d) shall have the right thereafter by
exercising the Warrant at any time prior to the expiration of the Warrant, to
purchase the kind and amount of shares of stock and other securities and
property receivable upon such Organic Change. In the event of any Organic
Change, appropriate provision shall be made by the Company with respect to the
rights and interests of the Holder of this Warrant to the end that the
provisions hereof (including, without limitation, provisions for adjustments of
the Exercise Price and of the number of shares purchasable and receivable upon
the exercise of this Warrant) shall thereafter be applicable, in relation to any
shares of stock, securities or assets thereafter deliverable upon the exercise
hereof. Any such provision shall include provision or adjustments which shall be
as nearly equivalent as may be practicable to the adjustments provided for in
the Warrant. The foregoing provisions of this Section (i) shall similarly apply
to successive Organic Changes.

         (j) SECURITIES LAW COMPLIANCE.

                  (i) The Holder of the Warrant, by acceptance hereof,
acknowledges that the Warrant and the shares of Common Stock to be issued upon
exercise hereof or conversion thereof are being acquired solely for the Holder's
own account and not as a nominee for any other party, and for investment, and
that the Holder will not offer, sell, transfer, assign or otherwise dispose of
this Warrant or any shares of Common Stock to be issued upon exercise hereof or
conversion thereof except under circumstances that will not result in a
violation of the Securities Act of 1933, as amended (the "ACT") or any state
securities laws. Upon exercise of the Warrant, the Holder shall, if requested by
the Company, confirm in writing, in a form reasonably satisfactory to the
Company, that the shares of Common Stock so purchased are being acquired solely
for the Holder's own account and not as a nominee for any other party, for
investment, and not with a view toward distribution or resale.

                  (ii) If appropriate, the Warrant and any Warrants issued upon
partial exercise or substitution or upon assignment or transfer pursuant to
Section (a) or Section (d), as the case may be, and all shares of Common Stock
issued upon exercise hereof or conversion thereof shall be stamped or imprinted
with legends setting forth the restrictions on transfer arising under applicable
federal and state securities laws.

         (k) RIGHT TO CONVERT WARRANT INTO COMMON STOCK.

                  (i) RIGHT TO CONVERT. The Holder shall have the right to
require the Company to convert this Warrant provided in this Section (k), into
Common Stock (the "NET CONVERSION RIGHT"). Upon exercise of the Net Conversion
Right, the Company shall deliver to the Holder (without payment by the Holder of
any Exercise Price or of any other cash or consideration) that number of shares
of Common Stock equal to the quotient obtained by dividing (x) the value of this
Warrant at the time the Net Conversion Right is exercised (determined by
subtracting the aggregate Exercise Price in effect immediately prior to the
exercise of the Net Conversion Right from the aggregate fair market value of the
shares of 





                                       8.
<PAGE>   9

Common Stock issuable upon exercise of this Warrant immediately prior to the
exercise of the Net Conversion Right) by (y) the fair market value of one share
of Common Stock immediately prior to the exercise of the Net Conversion Right.

                  (ii) METHOD OF EXERCISE. The Net Conversion Right may be
exercised by the Holder by the surrender of this Warrant at the principal office
of the Company together with a written statement specifying that the Holder
thereby intends to exercise the Net Conversion Right. Certificates for the
shares of Common Stock issuable upon exercise of the Net Conversion Right shall
be delivered to the Holder within five (5) days following the Company's receipt
of this Warrant together with the aforesaid written statement.

                  (iii) DETERMINATION OF FAIR MARKET VALUE. For purposes of this
Section (k), fair market value of a share of Common Stock as of a particular
date (the "DETERMINATION DATE") shall be determined in accordance with the
following:

                           (1) If the Common Stock is listed on a national
securities exchange or admitted to unlisted trading privileges on such exchange
or listed for trading on the NASDAQ National Market System, the fair market
value shall be the average of the closing price of the Common Stock on such
exchange or system for each of the last five (5) business days prior to the date
of exercise of this Warrant;

                           (2) If the Common Stock is not so listed or admitted
to unlisted trading privileges, the fair market value shall be the average of
the closing price reported by the National Quotation Bureau, Inc., for each of
the last five (5) business days prior to the date of the exercise of this
Warrant; or

                           (3) If the Common Stock is not so listed or admitted
to unlisted trading privileges and bid and asked prices are not so reported, the
fair market value shall be an amount determined in good faith by the Board of
Directors of the Company which shall not be less than the book value thereof as
at the end of the most recent fiscal year of the Company ending prior to the
date of the exercise of the Warrant, determined in such reasonable manner as may
be prescribed by the Board of Directors of the Company.

         (l) ISSUE TAX. The issuance of certificates for shares of Common Stock
upon the exercise of the Warrant shall be made without charge to the Holder of
the Warrant for any issue tax (other than any applicable income taxes) in
respect thereof; provided, however, that the Company shall not be required to
pay any tax which may be payable in respect of any transfer involved in the
issuance and delivery of any certificate in a name other than that of the then
current Holder of the Warrant being exercised.

         (m) CLOSING OF BOOKS. The Company will at no time close its transfer
books against the transfer of any warrant or of any shares of Common Stock
issued or issuable upon the exercise of any warrant in any manner which
interferes with the timely exercise of this Warrant.

         (n) MARKET STAND-OFF AGREEMENT. The Company (or a representative of the
underwriters) may, in connection with an underwritten registration of the
offering of any securities of the Company under the Act, require that the Holder
not sell, dispose of (other than to donees who agree to be similarly bound),
transfer, make any short sale of, grant any option for 






                                       9.
<PAGE>   10

the purchase of, or enter into any hedging or similar transaction with the same
economic effect as a sale, any Common Stock or other securities of the Company
held by the undersigned, for a period of time specified by the underwriters(s)
(not to exceed one hundred eighty (180) days) following the effective date of
the registration statement of the Company filed under the Act relating to the
Company's initial public offering and not to exceed ninety (90) days following a
subsequent underwritten registration. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to
Common Stock or other securities held by the Holder until the end of such
period.

         (o) AMENDMENTS. Neither the Warrant nor any term hereof may be changed,
waived, discharged or terminated without the prior written consent of the
Holder.

         (p) NO IMPAIRMENT. The Company will not avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Company, but will at all times in good faith assist in the
carrying out of all the provisions of this Warrant and in the taking of all such
action as may be necessary or appropriate in order to protect the rights of any
Holder.

         (q) GOVERNING LAW. This Agreement shall be governed by and construed
under the laws of the State of Colorado, without regard to the conflict of law
provisions therein.

         (r) NOTICES. All notices and other communications required or permitted
hereunder shall be in writing and shall be mailed by first class mail, postage
prepaid, addressed (a) if to the Holder, to BT Alex. Brown Incorporated, 1 South
Street, Baltimore, Maryland 21202, Attention: Thomas Hitchner, or (b) if to the
Company, to 1155 Kelly Johnson Blvd., Suite 400, Colorado Springs, Colorado
80920, or at such other address as to the Company shall have furnished to the

                           STOCK RESTRICTION AGREEMENT



         This Agreement is made as of the 8th day of April, 1997 (the "Effective
Date"), by and between USA.NET, Inc., a Delaware corporation (the
"Corporation"), and John W. Street ("Founder").

         WHEREAS, Founder is the holder of an aggregate of 161,102 shares of the
Corporation's Common Stock (the "Common Stock Shares") and 322,208 shares of the
Corporation's Series A Preferred Stock (the "Series A Shares") (the Common Stock
Shares and the Series A Shares are collectively referred to hereinafter as the
"Stock");

         WHEREAS, the Corporation desires to issue and sell shares of its Series
B Preferred Stock to the American Express Travel Related Services Company, Inc.
("TRS");

         WHEREAS, TRS has imposed, as a condition to the purchase of such Series
B Preferred Stock, the requirement that Founder enter into an agreement
containing the provisions set forth herein; and

         WHEREAS, the purchase of Series B Preferred Stock by TRS is in the best
interests of the Corporation and Founder;.

         NOW, THEREFORE, in consideration of the premises set forth herein, the
continued employment of the Founder, and for other good and valuable
consideration, the sufficiency of which is hereby acknowledged, the parties
hereto hereby agree as follows:

         1.       All shares of Stock shall be subject to the option set forth
in this paragraph 1 ("Purchase Option"):

                  (a)      In the event that Founder voluntarily ceases to be 
an employee or director of, or consultant to, the Corporation or (ii) Founder is
terminated for Cause (as defined below) by the Corporation (including a parent
or subsidiary of the Corporation) at any time prior to the earlier of:

                           (i)      the date three years from the date hereof;

                           (ii)     the closing of the  Corporation's  sale,  
lease or other disposition of all or substantially all of its assets;

                           (iii)    the closing of any consolidation or merger 
of the Corporation with or into any other corporation or other entity or person,
or any other corporate reorganization, in which the stockholders of the
Corporation immediately prior to such consolidation, merger or reorganization,
own less than 50% of the Corporation's voting power immediately after such
consolidation, merger or reorganization, or any transaction or series of related
transactions in which in excess of fifty percent (50%) of the Corporation's
voting power is transferred;



                                       1.
<PAGE>   2

                           (iv)     the liquidation, dissolution or winding up 
of the Corporation; or

                           (v)      Founder's  death or total and  permanent  
disability (as defined in Section 22(e)(3) of the Internal Revenue Code of 1986,
as amended.

                  then the Corporation (or its assignee) shall have the right at
any time within ninety (90) days after such cessation of employment or service
as a director or consultant (or such longer period as may be determined by the
Corporation if such later repurchase is deemed necessary by the Corporation for
treatment of its stock as Qualified Small Business Stock under Section 1202 of
the Internal Revenue Code of 1986, as amended, and regulations promulgated
thereunder), to exercise its option to repurchase from Founder or his personal
representative, as the case may be, any or all of the shares of Stock. Any such
repurchase shall be at a price per share equal to (i) with respect to the Common
Stock Shares, Fifty-Seven Cents ($.57) and (ii) with respect to the Series A
Shares, Four Dollars Seventy-Six Cents ($4.76).

                  (b)      The Corporation shall pay for any of the Stock 
purchased pursuant to its Purchase Option in cash.

                  (c)      As used herein, employment with the Corporation shall
include employment with an affiliate of the Corporation.

                  (d)      "CAUSE" as used herein shall mean: (i) dishonesty 
which is not the result of an inadvertent or innocent mistake of Founder with
respect to the Corporation or any of its subsidiaries; (ii) willful misfeasance
or nonfeasance of duty by Founder that materially injures the reputation,
business or business relationships of the Corporation or any of its subsidiaries
or any of their respective officers, directors or executives; (iii) any conduct
which would be sufficient to criminally charge Founder with the commission of a
crime involving moral turpitude or a crime other than a vehicle offense which
could reflect in some material fashion unfavorably upon the business or business
relationships of the Corporation or any of its subsidiaries or any of their
respective officers, directors or executives; (iv) willful or prolonged absence
from work by Founder (other than by reason of disability due to physical or
mental illness) or failure, neglect or refusal by Founder to perform his duties
and responsibilities without the same being corrected upon thirty (30) days
prior written notice; or (v) if Founder materially violates any term of this
Agreement or the Corporation's employment policies and procedures (including but
not limited to the Corporation's policies with respect to sexual harassment and
discrimination) and such action or failure is not remedied or reasonable steps
to effect such remedy are not commenced within thirty (30) days of written
notice.

         2.       The Purchase Option may be exercised by giving written notice
of exercise delivered or mailed as provided in paragraph 11. Upon providing of
such notice and payment or tender of the purchase price, the Corporation shall
become the legal and beneficial owner of the Stock being purchased and all
rights and interests therein or related thereto.




                                       2.
<PAGE>   3

         3.       If from time to time during the term of the Purchase Option 
there is any stock dividend or liquidating dividend or distribution of cash
and/or property, stock split or other change in the character or amount of any
of the outstanding securities of the Corporation then, in such event, any and
all new, substituted or additional securities or other property to which Founder
is entitled by reason of his ownership of Stock will be immediately subject to
the Purchase Option and be included in the word "Stock" for all purposes of the
Purchase Option with the same force and effect as the shares of Stock then
subject to the Purchase Option. While the total repurchase price shall remain
the same after each such event, the repurchase price per share of Common Stock
Shares and Series A Shares, as applicable, upon exercise of the Purchase Option
shall be appropriately adjusted.

         4.       All certificates representing any shares of Stock of the 
Corporation subject to the provisions of this Agreement shall have endorsed
thereon legends in substantially the following form:

                  "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO AN
                  OPTION SET FORTH IN AN AGREEMENT BETWEEN THE CORPORATION AND
                  THE REGISTERED HOLDER, OR HIS PREDECESSOR IN INTEREST, A COPY
                  OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THIS
                  CORPORATION. ANY TRANSFER OR ATTEMPTED TRANSFER OF ANY SHARES
                  SUBJECT TO SUCH OPTION IS VOID WITHOUT THE PRIOR EXPRESS
                  WRITTEN CONSENT OF THE ISSUER OF THESE SHARES."

         5.       As security for his faithful performance of the terms of this
Agreement and to insure the availability for delivery of Founder's Stock upon
exercise of the Purchase Option herein provided for, Founder agrees, at the
closing hereunder (or as soon thereafter as practicable), to deliver (or have
the Corporation deliver on the Founder's behalf) to and deposit with the
Secretary of the Corporation ("Escrow Agent"), as Escrow Agent in this
transaction, two (2) stock assignments duly endorsed (with the dates and number
of shares left blank) in the forms attached hereto as Exhibit A, together with
the certificate or certificates evidencing all of the Stock subject to the
Purchase Option; said documents are to be held by the Escrow Agent and delivered
by said Escrow Agent pursuant to the Joint Escrow Instructions of the
Corporation and Founder set forth in Exhibit B attached hereto and incorporated
herein by this reference, which instructions shall also be delivered to the
Escrow Agent at the closing hereunder (or as soon thereafter as practicable).

         6.       Founder shall not sell or transfer any shares of the Stock 
then subject to the Purchase Option. Without in any way limiting the foregoing,
Founder further agrees that he shall in no event make any disposition of all or
any portion of the Stock unless and until:

                  (a)      There is then in effect a registration statement 
under the Act covering such proposed disposition and such disposition is made in
accordance with said registration statement; or

                  (b)      (i) He shall have notified the Corporation of the 
proposed disposition and shall have furnished the Corporation with a detailed
statement of the circumstances surrounding the proposed disposition, (ii) he
shall have furnished the Corporation with an opinion of his own counsel to the
effect that such disposition will not require registration of such shares under




                                       3.
<PAGE>   4

the Act; and (iii) such opinion of his counsel shall have been concurred in by
counsel for the Corporation, such concurrence not to be unreasonably withheld,
and the Corporation shall have advised him of such concurrence.

         7.       The Corporation shall not be required (i) to transfer on its
books any shares of Stock of the Corporation which shall have been sold or
transferred in violation of any of the provisions set forth in this Agreement or
(ii) to treat as owner of such shares or to accord the right to vote as such
owner or to pay dividends to any transferee to whom such shares shall have been
so transferred.

         8.       Subject to the provisions of this Agreement, Founder (but not
any unapproved transferee) shall, during the term of this Agreement, exercise
all rights and privileges of a shareholder of the Corporation with respect to
the Stock.

         9.       This Agreement is not an employment contract and nothing in
this Agreement shall be deemed to create in any way whatsoever any obligation on
the part of Founder to continue in the employ of the Corporation, or of the
Corporation to continue Founder in the employ of the Corporation.

         10.      The parties agree to execute such further instruments and to
take such further action as reasonably may be necessary to carry out the intent
of this Agreement.

         11.      Any notice required or permitted hereunder shall be given in
writing and shall be deemed effectively given upon personal delivery or upon
deposit in any United States Post Office Box, by registered or certified mail
with postage and fees prepaid, addressed to the other party hereto at his
address hereinafter shown below his signature or at such other address as such
party may designate by ten (10) days' advance written notice to the other party
hereto.

         12.      This Agreement shall bind and inure to the benefit of the
successors and assigns of the Corporation and, subject to the restrictions on
transfer herein set forth, inure to the benefit of and be binding upon Founder,
his heirs, executors, administrators, successors, and assigns. Without limiting
the generality of the foregoing, the Purchase Option of the Corporation
hereunder shall be assignable by the Corporation at any time or from time to
time, in whole or in part.

         13.      This Agreement shall be governed by and construed in
accordance with the laws of the State of Colorado, as such laws are applied by
Colorado courts to contracts made and to be performed entirely in Colorado by
residents of that State. The parties agree that any action brought by either
party to interpret or enforce any provision of this Agreement shall be brought
in, and each party agrees to, and does hereby, submit to the jurisdiction and
venue of, the appropriate state or federal court for the district encompassing
the Corporation's principal office.

         14.      The parties acknowledge and agree that TRS shall be a third
party beneficiary to this Agreement, entitled to enforce its terms. In addition,
this Agreement may not be terminated without the prior written consent of TRS.

USA.NET, Inc.

Colorado Springs, CO 80903

Dear Sir or Madam:

         As Escrow Agent for both USA.NET, Inc., a Delaware corporation (the
"Corporation"), and John W. Street ("Shareholder"), you are hereby authorized
and directed to hold the documents delivered to you pursuant to the terms of
that certain Stock Restriction Agreement ("Agreement") dated as of April 8,
1997, to which a copy of these Joint Escrow Instructions is attached as Exhibit
B, in accordance with the following instructions:

         1. If the Corporation shall elect to exercise the Purchase Option set
forth in the Agreement, the Corporation shall give to Shareholder and you a
written notice specifying the number of shares of Stock to be purchased, the
purchase price, and the time for a closing thereunder at the principal office of
the Corporation. Shareholder and the Corporation hereby irrevocably authorize
and direct you to close the transaction contemplated by such notice in
accordance with the terms of said notice.

         2. At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred and (c) to deliver the same, together with the certificate
evidencing the shares of Stock to be transferred, to the Corporation against the
simultaneous delivery to you of the purchase price (by check, cancellation of
all or a portion of any outstanding indebtedness of Shareholder to the
Corporation, or as otherwise may be provided for in the Agreement) for the
number of shares of Stock being purchased pursuant to the exercise of the
Purchase Option.

         3. Shareholder irrevocably authorizes the Corporation to deposit with
you any certificates evidencing shares of Stock to be held by you hereunder and
any additions and substitutions to said shares as referred to in the Agreement.
Shareholder does hereby irrevocably constitute and appoint you as his
attorney-in-fact and agent for the term of this escrow to execute with respect
to such securities all documents necessary or appropriate to make such
securities negotiable and complete any transaction herein contemplated,
including but not limited to any appropriate filing with state or government
officials or bank officials. Subject to the provisions of this paragraph 3,
Shareholder shall exercise all rights and privileges of a shareholder of the
Corporation while the Stock is held by you.

         4. This escrow shall terminate upon the exercise in full or expiration
of the Purchase Option, whichever occurs first.
                                     



                                       1.


<PAGE>   10

         5. If at the time of termination of this escrow you should have in your
possession any documents, securities, or other property belonging to
Shareholder, you shall deliver all of the same to Shareholder and shall be
discharged of all further obligations hereunder.

         6. Your duties hereunder may be altered, amended, modified or revoked
only by a writing signed by all of the parties hereto.

         7. You shall be obligated only for the performance of such duties as
are specifically set forth herein and may rely and shall be protected in relying
or refraining from acting on any instrument reasonably believed by you to be
genuine and to have been signed or presented by the proper party or parties. You
shall not be personally liable for any act you may do or omit to do hereunder as
Escrow Agent or as attorney-in-fact for Shareholder while acting in good faith
and in the exercise of your own good judgment, and any act done or omitted by
you pursuant to the advice of your own attorneys shall be conclusive evidence of
such good faith.

         8. You are hereby expressly authorized to disregard any and all
warnings given by any of the parties hereto or by any other person or
corporation, excepting only orders or process of courts of law, and are hereby
expressly authorized to comply with and obey orders, judgments or decrees of any
court. In case you obey or comply with any such order, judgment or decree of any
court, you shall not be liable to any of the parties hereto or to any other
person, firm or corporation by reason of such compliance, notwithstanding any
such order, judgment or decree being subsequently reversed, modified, annulled,
set aside, vacated or found to have been entered without jurisdiction.

         9. You shall not be liable in any respect on account of the identity,
authorities or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder.

         10. You shall not be liable for the outlawing of any rights under the
Statute of Limitations with respect to these Joint Escrow Instructions or any
documents deposited with you.

         11. Your responsibilities as Escrow Agent hereunder shall terminate if
you shall cease to be Secretary of the Corporation or if you shall resign by
written notice to each party. In the event of any such termination, the
Corporation shall appoint your successor as Secretary of the Corporation as
successor Escrow Agent.

         12. If you reasonably require other or further instruments in
connection with these Joint Escrow Instructions or obligations in respect
hereto, the necessary parties hereto shall join in furnishing such instruments.

         13. It is understood and agreed that should any dispute arise with
respect to the delivery and/or ownership or right of possession of the
securities held by you hereunder, you are authorized and directed to retain in
your possession without liability to anyone all or any part of said securities
until such dispute shall have been settled either by mutual written agreement of
the parties concerned or by a final order, decree or judgment of a court of
competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you shall be under no duty whatsoever to institute or defend
any such proceedings.

responsible for all fees generated by such legal counsel in connection with your

         17. This instrument shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and permitted assigns.

                            NON-COMPETITION AGREEMENT

         This Non-Competition Agreement (the "AGREEMENT") is made as of the 8th
day of April, 1997 by and between USA.NET, Inc., a Delaware corporation (the
"COMPANY") and John W. Street ("EMPLOYEE"). This is the Non-Competition
Agreement contemplated by that certain Series B Preferred Stock Purchase
Agreement, dated as of the date hereof by and between the Company and American
Express Travel Related Services, Inc. ("TRS") (the "PURCHASE AGREEMENT").

         WHEREAS, the Company and TRS have entered into the Purchase Agreement
providing for the acquisition by TRS of the Shares (as defined in the Purchase
Agreement);

         WHEREAS, Employee is a key management employee and stockholder of the
Company;

         WHEREAS, in order to protect the value of the Shares (as defined in the
Purchase Agreement) being acquired by TRS, TRS requires that Employee agree to
certain restrictions on Employee's ability to compete with the Company in the
future;

         WHEREAS, it is expected that Employee will personally benefit from the
investment of TRS in the Company;

         WHEREAS, the Company, Employee and TRS desire that the transactions
contemplated by the Purchase Agreement be consummated; and

         WHEREAS, pursuant to the terms and conditions of Sections 5.2 and 5.3
of the Purchase Agreement, Employee shall execute and deliver this Agreement to
the Company prior to the Closing (as defined in the Purchase Agreement).

         NOW, THEREFORE, as inducement to TRS to proceed with the Closing and in
consideration of such Closing and of the mutual covenants and agreements
contained herein and in the Purchase Agreement and for other good and valuable
consideration hereby acknowledged, intending to be legally bound, the parties
hereto do hereby agree as follows:

1.       NON-COMPETITION. Employee agrees that he shall not, directly or
indirectly, from the date commencing three (3) years after the date on which
Employee's employment is terminated by Employee or the Company, whether as an
owner, consultant, partner, joint venturer, stockholder, broker, agent,
principal, trustee, licensor or in any capacity whatsoever (the "RESTRICTION
PERIOD"): (a) own, manage, operate, join, control, finance or participate in the
ownership, management, operation, control or financing of, or be connected as an
officer, director, employee, partner, principal, agent, representative,
consultant, licensor, licensee or otherwise with, any business or enterprise
which is competitive with the Company in the business of providing Internet
E-mail services (the "BUSINESS"), or (b) engage in any other manner, in any
business which is competitive with the Company in the Business as conducted by
the Company at the time Employee's employment relationship with the Company is
terminated; provided, however, that the acquisition or ownership of less than 5%
of the outstanding shares of any corporation engaged in the Business will not
constitute a violation of 




                                       1.
<PAGE>   2

this Agreement. Employee agrees that during the Restricted Period, Employee
shall not employ, or directly or indirectly solicit for employment or advise or
recommend to any other person that he or she employ or solicit for employment,
any person employed at that time by the Company, its parent, subsidiaries or
affiliates.

2.       JUDICIAL LIMITATION. In the event that any provision of this Agreement
is more restrictive than permitted by the law of the jurisdiction in which the
Company seeks enforcement thereof, the provisions of this Agreement shall be
limited only to that extent that a judicial determination finds the same to be
unreasonable or otherwise unenforceable. Such invalidity or unenforceability
shall not affect any other terms herein but such term shall be deemed deleted,
and such deletion shall not affect the validity of the other terms hereof. In
addition, if any one or more of the terms contained in this Agreement shall for
any reason be held to be excessively broad or of an overly long duration that
term shall be construed in a manner to enable it to be enforced to the extent
compatible with applicable law. Moreover, notwithstanding any judicial
determination that any provision of this Agreement is not specifically
enforceable, the parties intend that the Company shall nonetheless be entitled
to recover monetary damages as a result of any breach hereof.

3.       INJUNCTIVE RELIEF. In view of the nature of the rights in goodwill,
business reputation and prospects of the Company and the value of the Shares to
be protected under this Agreement, Employee understands and agrees that the
Company could not be reasonably or adequately compensated in damages in an
action at law for Employee's breach of its obligations hereunder. Accordingly,
Employee specifically agrees that the Company shall be entitled to temporary and
permanent injunctive relief to enforce the provisions of this Agreement and that
such relief may be granted without the necessity of proving actual damages. This
provision with respect to injunctive relief shall not, however, diminish the
right of the Company to claim and recover damages in addition to injunctive
relief.

4.       WAIVER. The failure of the Company to enforce at any time any of the
provisions of this Agreement or to require at any time performance by Employee
of the provisions hereof shall in no way be construed to be a waiver of such
provisions or to affect either the validity of this Agreement, or any part
hereof, or the right of the Company thereafter to enforce each and every
provision in accordance with the terms of this Agreement.

5.       SEVERABILITY. The invalidity or unenforceability of any particular
provision of this Agreement shall not affect the other provisions hereof, and
this Agreement shall be construed in all respects as if such invalid or
unenforceable provisions were omitted.

6.       ASSIGNABILITY. This Agreement shall be freely assignable by the Company
and shall inure to the benefit of its successors and assigns.

7.       TERMINATION IN THE EVENT OF A CHANGE OF CONTROL. This Agreement shall
terminate in the event of (a) any consolidation or merger of the Company with or
into any other corporation or other entity or person, or any other corporate
reorganization, 



                                       2.
<PAGE>   3

in which the stockholders of the Company immediately prior to such
consolidation, merger or reorganization, own less than 50% of the Company's
voting power immediately after such consolidation, merger or reorganization, or
any transaction or series of related transactions in which in excess of fifty
percent (50%) of the Company's voting power is transferred (an "Acquisition");
or (b) a sale, lease or other disposition of all or substantially all of the
assets of the Company (an "Asset Transfer"); provided, however, that TRS is not
the acquiring party in such Acquisition or Asset Transfer.

8.       GOVERNING LAW. This Agreement shall be governed by the laws of the
State of Colorado without regard to its conflicts-of-laws rules.

9.       AMENDMENTS. This Agreement may not be amended, altered or modified
other than by a written agreement between the parties hereto.

10.      COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original and all of which
shall together constitute one and the same instrument.

                               INDEMNITY AGREEMENT


         THIS AGREEMENT is made and entered into this ____ day of _________,
1999 by and between USA.NET, INC. a Delaware corporation (the "Corporation"),
and ____________ ("Agent").

                                    RECITALS

         WHEREAS, Agent performs a valuable service to the Corporation in
his/her capacity as _______________ of the Corporation;

         WHEREAS, the stockholders of the Corporation have adopted bylaws (the
"Bylaws") providing for the indemnification of the directors, officers,
employees and other agents of the Corporation, including persons serving at the
request of the Corporation in such capacities with other corporations or
enterprises, as authorized by the Delaware General Corporation Law, as amended
(the "Code");

         WHEREAS, the Bylaws and the Code, by their non-exclusive nature, permit
contracts between the Corporation and its agents, officers, employees and other
agents with respect to indemnification of such persons; and

         WHEREAS, in order to induce Agent to continue to serve as
______________ of the Corporation, the Corporation has determined and agreed to
enter into this Agreement with Agent;

         NOW, THEREFORE, in consideration of Agent's continued service as
_______________ after the date hereof, the parties hereto agree as follows:

                                    AGREEMENT

         1.       SERVICES TO THE CORPORATION. Agent will serve, at the will 
of the Corporation or under separate contract, if any such contract exists, as
______________ of the Corporation or as a director, officer or other fiduciary
of an affiliate of the Corporation (including any employee benefit plan of the
Corporation) faithfully and to the best of his ability so long as he is duly
elected and qualified in accordance with the provisions of the Bylaws or other
applicable charter documents of the Corporation or such affiliate; provided,
however, that Agent may at any time and for any reason resign from such position
(subject to any contractual obligation that Agent may have assumed apart from
this Agreement) and that the Corporation or any affiliate shall have no
obligation under this Agreement to continue Agent in any such position.

         2.       INDEMNITY OF AGENT. The Corporation hereby agrees to hold 
harmless and indemnify Agent to the fullest extent authorized or permitted by
the provisions of the Bylaws and the Code, as the same may be amended from time
to time (but, only to the extent that such amendment permits the Corporation to
provide broader indemnification rights than the Bylaws or the Code permitted
prior to adoption of such amendment).




                                       1.
<PAGE>   2

         3.       ADDITIONAL INDEMNITY. In addition to and not in limitation of
the indemnification otherwise provided for herein, and subject only to the
exclusions set forth in Section 4 hereof, the Corporation hereby further agrees
to hold harmless and indemnify Agent:

                  (a)      against any and all expenses (including attorneys'
fees), witness fees, damages, judgments, fines and amounts paid in settlement
and any other amounts that Agent becomes legally obligated to pay because of any
claim or claims made against or by him in connection with any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
arbitrational, administrative or investigative (including an action by or in the
right of the Corporation) to which Agent is, was or at any time becomes a party,
or is threatened to be made a party, by reason of the fact that Agent is, was or
at any time becomes a director, officer, employee or other agent of Corporation,
or is or was serving or at any time serves at the request of the Corporation as
a director, officer, employee or other agent of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise;
and

                  (b)      otherwise to the fullest extent as may be provided to
Agent by the Corporation under the non-exclusivity provisions of the Code and
Section 43 of the Bylaws.

         4.      LIMITATIONS ON ADDITIONAL INDEMNITY. No indemnity pursuant to
Section 3 hereof shall be paid by the Corporation:

                  (a)      on account of any claim against Agent for an 
accounting of profits made from the purchase or sale by Agent of securities of
the Corporation pursuant to the provisions of Section 16(b) of the Securities
Exchange Act of 1934 and amendments thereto or similar provisions of any
federal, state or local statutory law;

                  (b)      on account of Agent's conduct that was knowingly
fraudulent or deliberately dishonest or that constituted willful misconduct;

                  (c)      on account of Agent's conduct that constituted a 
breach of Agent's duty of loyalty to the Corporation or resulted in any personal
profit or advantage to which Agent was not legally entitled;

                  (d)      for which payment is actually made to Agent under a
valid and collectible insurance policy or under a valid and enforceable
indemnity clause, bylaw or agreement, except in respect of any excess beyond
payment under such insurance, clause, bylaw or agreement;

                  (e)      if indemnification is not lawful (and, in this 
respect, both the Corporation and Agent have been advised that the Securities
and Exchange Commission believes that indemnification for liabilities arising
under the federal securities laws is against public policy and is, therefore,
unenforceable and that claims for indemnification should be submitted to
appropriate courts for adjudication); or

                  (f)      in connection with any proceeding (or part thereof)
initiated by Agent, or any proceeding by Agent against the Corporation or its
directors, officers, employees or other agents, unless (i) such indemnification
is expressly required to be made by law, (ii) the proceeding was authorized by
the Board of Directors of the Corporation, (iii) such indemnification is
provided by the Corporation, in its sole discretion, pursuant to the powers


                                       2.

<PAGE>   3


vested in the Corporation under the Code, or (iv) the proceeding is initiated
pursuant to Section 9 hereof.

         5.      CONTINUATION OF INDEMNITY. All agreements and obligations of
the Corporation contained herein shall continue during the period Agent is a
director, officer, employee or other agent of the Corporation (or is or was
serving at the request of the Corporation as a director, officer, employee or
other agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise) and shall continue thereafter so long as Agent
shall be subject to any possible claim or threatened, pending or completed
action, suit or proceeding, whether civil, criminal, arbitrational,
administrative or investigative, by reason of the fact that Agent was serving in
the capacity referred to herein.

         6.      PARTIAL INDEMNIFICATION. Agent shall be entitled under this
Agreement to indemnification by the Corporation for a portion of the expenses
(including attorneys' fees), witness fees, damages, judgments, fines and amounts
paid in settlement and any other amounts that Agent becomes legally obligated to
pay in connection with any action, suit or proceeding referred to in Section 3
hereof even if not entitled hereunder to indemnification for the total amount
thereof, and the Corporation shall indemnify Agent for the portion thereof to
which Agent is entitled.

         7.      NOTIFICATION AND DEFENSE OF CLAIM. Not later than thirty (30)
days after receipt by Agent of notice of the commencement of any action, suit or
proceeding, Agent will, if a claim in respect thereof is to be made against the
Corporation under this Agreement, notify the Corporation of the commencement
thereof; but the omission so to notify the Corporation will not relieve it from
any liability which it may have to Agent otherwise than under this Agreement.
With respect to any such action, suit or proceeding as to which Agent notifies
the Corporation of the commencement thereof:

                  (a)      the Corporation will be entitled to participate 
therein at its own expense;

                  (b)      except as otherwise provided below, the Corporation
may, at its option and jointly with any other indemnifying party similarly
notified and electing to assume such defense, assume the defense thereof, with
counsel reasonably satisfactory to Agent. After notice from the Corporation to
Agent of its election to assume the defense thereof, the Corporation will not be
liable to Agent under this Agreement for any legal or other expenses
subsequently incurred by Agent in connection with the defense thereof except for
reasonable costs of investigation or otherwise as provided below. Agent shall
have the right to employ separate counsel in such action, suit or proceeding but
the fees and expenses of such counsel incurred after notice from the Corporation
of its assumption of the defense thereof shall be at the expense of Agent unless
(i) the employment of counsel by Agent has been authorized by the Corporation,
(ii) Agent shall have reasonably concluded that there may be a conflict of
interest between the Corporation and Agent in the conduct of the defense of such
action or (iii) the Corporation shall not in fact have employed counsel to
assume the defense of such action, in each of which cases the fees and expenses
of Agent's separate counsel shall be at the expense of the Corporation. The
Corporation shall not be entitled to assume the defense of any action, suit or
proceeding brought by or on behalf of the Corporation or as to which Agent shall
have made the conclusion provided for in clause (ii) above; and


                                       3.

<PAGE>   4

                  (c)      the Corporation shall not be liable to indemnify
Agent under this Agreement for any amounts paid in settlement of any action or
claim effected without its written consent, which shall not be unreasonably
withheld. The Corporation shall be permitted to settle any action except that it
shall not settle any action or claim in any manner which would impose any
penalty or limitation on Agent without Agent's written consent, which may be
given or withheld in Agent's sole discretion.

         8.       EXPENSES. The Corporation shall advance, prior to the final
disposition of any proceeding, promptly following request therefor, all expenses
incurred by Agent in connection with such proceeding upon receipt of an
undertaking by or on behalf of Agent to repay said amounts if it shall be
determined ultimately that Agent is not entitled to be indemnified under the
provisions of this Agreement, the Bylaws, the Code or otherwise.

         9.       ENFORCEMENT. Any right to indemnification or advances granted
by this Agreement to Agent shall be enforceable by or on behalf of Agent in any
court of competent jurisdiction if (i) the claim for indemnification or advances
is denied, in whole or in part, or (ii) no disposition of such claim is made
within ninety (90) days of request therefor. Agent, in such enforcement action,
if successful in whole or in part, shall be entitled to be paid also the expense
of prosecuting his claim. It shall be a defense to any action for which a claim
for indemnification is made under Section 3 hereof (other than an action brought
to enforce a claim for expenses pursuant to Section 8 hereof, provided that the
required undertaking has been tendered to the Corporation) that Agent is not
entitled to indemnification because of the limitations set forth in Section 4
hereof. Neither the failure of the Corporation (including its Board of Directors
or its stockholders) to have made a determination prior to the commencement of
such enforcement action that indemnification of Agent is proper in the
circumstances, nor an actual determination by the Corporation (including its
Board of Directors or its stockholders) that such indemnification is improper
shall be a defense to the action or create a presumption that Agent is not
entitled to indemnification under this Agreement or otherwise.

         10.      SUBROGATION. In the event of payment under this Agreement, the
Corporation shall be subrogated to the extent of such payment to all of the
rights of recovery of Agent, who shall execute all documents required and shall
do all acts that may be necessary to secure such rights and to enable the
Corporation effectively to bring suit to enforce such rights.

         11.      NON-EXCLUSIVITY OF RIGHTS. The rights conferred on Agent by
this Agreement shall not be exclusive of any other right which Agent may have or
hereafter acquire under any statute, provision of the Corporation's Certificate
of Incorporation or Bylaws, agreement, vote of stockholders or directors, or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding office.


                                       4.

<PAGE>   5

         12.      SURVIVAL OF RIGHTS.

                  (a)      The rights conferred on Agent by this Agreement shall
continue after Agent has ceased to be a director, officer, employee or other
agent of the Corporation or to serve at the request of the Corporation as a
director, officer, employee or other agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise and shall inure
to the benefit of Agent's heirs, executors and administrators.

                  (b)      The Corporation shall require any successor (whether
direct or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business or assets of the Corporation, expressly to
assume and agree to perform this Agreement in the same manner and to the same
extent that the Corporation would be required to perform if no such succession
had taken place.

         13.      SEPARABILITY. Each of the provisions of this Agreement is a
separate and distinct agreement and independent of the others, so that if any
provision hereof shall be held to be invalid for any reason, such invalidity or
unenforceability shall not affect the validity or enforceability of the other
provisions hereof. Furthermore, if this Agreement shall be invalidated in its
entirety on any ground, then the Corporation shall nevertheless indemnify Agent
to the fullest extent provided by the Bylaws, the Code or any other applicable
law.

         14.      GOVERNING LAW. This Agreement shall be interpreted and 
enforced in accordance with the laws of the State of Delaware.

         15.      AMENDMENT AND TERMINATION. No amendment, modification, 
termination or cancellation of this Agreement shall be effective unless in
writing signed by both parties hereto.

         16.      IDENTICAL COUNTERPARTS. This Agreement may be executed in one
or more counterparts, each of which shall for all purposes be deemed to be an
original but all of which together shall constitute but one and the same
Agreement. Only one such counterpart need be produced to evidence the existence
of this Agreement.

         17.      HEADINGS. The headings of the sections of this Agreement are
inserted for convenience only and shall not be deemed to constitute part of this
Agreement or to affect the construction hereof.

         18.      NOTICES. All notices, requests, demands and other 
communications hereunder shall be in writing and shall be deemed to have been
duly given (i) upon delivery if delivered by hand to the party to whom such
communication was directed or (ii) upon the third business day after the date on
which such communication was mailed if mailed by certified or registered mail
with postage prepaid:

                  (a)       If to Agent, at the address indicated on the 
signature page hereof.

                        CO - MARKETING PROGRAM AGREEMENT

This Co - Marketing Agreement (the " Agreement") is entered into this 8th day of
April 1997, by and between USA.NET, Inc., a Delaware corporation ("Company"),
and American Express Travel Related Services Company, Inc., a New York
corporation ("AMEX").

WHEREAS, Company is engaged in, among other things, the business of promoting,
selling and providing consumer and other services associated with an e-mail
screening and address location; and

WHEREAS, Company and AMEX have entered into agreements with respect to a current
and future investment by AMEX in the Company;

WHEREAS, AMEX desires to have offered, and to participate with Company in the
promotion of such services with unique enhancements to certain of its current
and future holders of an American Express(R) charge, credit or debit card (each
a "Cardmember") and certain other individuals (together with Cardmembers,
"Customers") on the terms and conditions of this Agreement;

NOW THEREFORE, in consideration of the mutual promises and covenants contained
in this Agreement, the parties hereto agree as follows:

1.   THE SERVICE:

(a)  Description. AMEX hereby retains Company to, and Company agrees to, provide
     Customers with an opportunity to enroll in the e-mail service offered to
     the Company's customers from time to time (the "Basic Service;" the Basic
     Service as offered on the date hereof is more specifically described in
     Exhibit A hereto), with changes and enhancements thereto as developed from
     time to time specifically for AMEX and approved by AMEX in its sole
     discretion (such changes and enhancements, the "Enhancements"; the Basic
     Service as changed or enhanced from time to time the "Service"), all in
     accordance with the terms hereof. As compared with the Basic Service, the
     Service will always have features, including by way of example additional
     services, reduced pricing or incentive offers, that will be exclusive to
     Customers. In the marketing and promotion of the Service to Customers, AMEX
     shall determine which Enhancements and features shall be included in the
     Service as so marketed and promoted.

(b)  Eligibility. AMEX alone shall determine the eligibility of particular
     Customers for enrollment in the Service. Enrollment fees, if any, shall be
     charged to the Card Account, if any, for the eligible Customer enrolled in
     the Service.

2.   PROMOTION OF THE SERVICE:

(a)  In accordance with the terms hereof, AMEX will use its best efforts to test
     and or assist Company in the definition of the promotion of Service to the
     Customers by participating in 


                                       1

<PAGE>   2

     Programs (as defined below) in the manner and to the extent provided in
     this Agreement. From time-to-time AMEX will engage in such other
     solicitation activities relating to the Service, or with respect to other
     products or services offered by Company, as Company and AMEX may mutually
     agree.

(b)  AMEX's Conditions: Prior to any participation by AMEX in a Program, (i) the
     features of the Service shall be defined to AMEX's satisfaction, (ii) the
     service delivery capabilities of the Company shall meet the minimum
     operation standards set forth on Exhibit B hereto, and (iii) the customer
     service capabilities of the Company shall meet the minimum operation
     standards of AMEX set forth on Exhibit B attached hereto as amended from
     time to time with Company's consent (the "Customer Service").

(c)  Programs: The parties acknowledge that they intend to test market the
     Service through various promotional approaches and channels. All marketing,
     including initiatives thereof, of the Service shall be deemed to be a
     "Program" hereunder. The parties agree that it is impractical to define now
     each Program that they may pursue and therefore agree to develop mutually a
     written marketing plan defining such Program which will identify the offers
     of the Service contemplated hereunder and which will be mutually updated by
     the parties no less frequently than once every three (3) months. All
     promotional materials (including without limitation, solicitation,
     fulfillment, Customer Service and retention materials) developed hereunder
     is herein referred to as "Promotional Materials."

(d)  Marketing Promotional Expenses and Certain Customer Service: All expenses
     and costs (including without limitation marketing research, marketing
     tests, public relations, list development, ad agency fees, software
     development (related to the user interface of the Service to Customers) and
     Customer Service limited to [**] times direct salary costs for incremental
     staff for [  **  ] after launch of each program not to exceed [  **  ] for
     each of the [     **     ] (the "Marketing Expenses") associated with a
     Program, whether conducted by AMEX or by the Company with AMEX's prior
     approval, shall be payable by the Company up to [     **    ] (the "Initial
     Marketing Dollars"). The restriction on the Initial Marketing Dollars set
     forth in the preceding sentence shall not extend beyond the Initial Term
     hereof. If AMEX exercises its option under the Series B Preferred Stock
     Purchase Agreement dated the date hereof to make the additional investment
     in the Company of at least [     **    ], then the Company shall be
     responsible for an additional [     **    ] (together with the Initial
     Marketing Dollars, the "Marketing Dollars") for the expenses and costs
     associated with such Program. The restriction on the Marketing Dollars from
     the additional investment shall not extend beyond the [      **      ]
     month period from the time of such investment unless the Agreement is
     terminated prior thereto.

     Upon reasonable notice to the Company, AMEX may make additional
     expenditures for Marketing Expenses; provided that AMEX shall be entitled
     to receive, and Company shall be obligated to remit to AMEX, a percentage
     of the gross revenues from the use of the Service by Customers acquired
     through the resulting marketing promotion. [                            
                                          **

                                                                         ]

(e)  Promotional Materials: The Company shall prepare Promotional Materials for
     all Programs offered pursuant to this Agreement at its expense (subject to
     the limitations set forth in subsection (d) hereof), provided that AMEX
     shall prepare Promotional Materials in connection with direct mail
     marketing initiatives hereunder at Company's expense (subject to the
     limitations set forth in subsection (d) hereof). Such materials shall be
     designed to solicit Customers to enroll in the Service. All Promotional
     Materials shall be subject to the prior written approval of AMEX. The
     Company shall be solely responsible for verifying the accuracy of all
     statements relating to the Service contained in the Promotional Materials.
     Promotional Materials may include, in AMEX's sole discretion, (i) AMEX's
     (or any of its affiliates' or licensees') brand imagery or (ii) Company's
     brand imagery in a manner that is acceptable to Company; provided however
     so long as the Company is the provider of the Service, AMEX will always
     identify the Company as such provider. It is agreed that neither party may
     use any of the other party's registered trademarks or service marks in the
     Promotional Materials or otherwise in connection with the promotion of the
     Service, except with the prior written consent of such other party and,
     then, only in accordance with such guidelines as the other party may from
     time-to-time reasonably establish concerning such use.

     Neither party shall refer to the other party, its services or its customers
     in any advertising, press release, marketing materials or other promotional
     materials of any kind without the prior written consent of the other party.
     The foregoing applies equally to materials relating to the Service and to
     materials not relating to the Service.

     Notwithstanding anything to the contrary herein, AMEX shall be deemed the
     sole and exclusive owner of all Promotional Materials.

3. FINANCIAL ARRANGEMENT:

(a)  AMEX shall be entitled to receive, and Company shall remit to AMEX, [     
       **        ] of gross revenues from the use of the Service by Customers
     except for Customers who were customers of the Company prior to the
     distribution of any Promotional Materials (the "Company Customers").
     Company shall remit such payments to AMEX within thirty (30) days after the
     end of each calendar month, along with back-up documentation reasonably
     acceptable to AMEX showing the calculation of the amount so paid. It is
     understood by the parties hereto that gross revenues of the Service shall
     be net of reasonable third party commissions for advertising sales directly
     relating to the Services (any disagreement relating to the amount of third
     party commissions shall be resolved by arbitration pursuant to Section 18)
     and shall include (i) revenues generated from advertisement on the Service
     as used by Customers (which advertisement shall accord with the AMEX
     advertisement policy set forth on Exhibit C hereto, as amended from time to
     time, (ii) fees charged to Customers for enrollment in the Service (the
     "Enrollment Fees"), which Enrollment Fees shall be 

**   INDICATES CONFIDENTIAL TREATMENT REQUESTED.


                                       3

<PAGE>   4

     determined by the parties hereto, and (iii) any other fees approved by the
     parties hereto from time to time. AMEX and the Company expressly
     acknowledge that the financial terms stated herein may be amended as the
     parties may agree in writing.

(b)  The parties hereto acknowledge that the revenues generated from the use of
     the Service by Company Customers that are provided the Service under the
     Domain Name Alternative (defined in Section 15) shall be subject to a
     revenue share between the parties hereto as the parties shall reasonably
     agree.

(c)  Company agrees that it will enter into an agreement ("Acceptance
     Agreement") for the acceptance of the American Express cards. Company
     understands that it will be responsible for paying any charges incurred in
     connection with the Acceptance Agreement, including the payment of any
     discount fees. (Any revenues to AMEX generated by the terms of the
     Acceptance Agreement shall not be calculated as part of the gross revenues
     for purposes of Section 3(a) hereto.) All Enrollment Fees and other fees
     payable by Customers will be billed to the Customers' Card Account, if any.
     Company shall be responsible for billing and collecting all fees (including
     the Enrollment Fee) payable by Customers for use of the Service.

4.   EXCLUSIVITY: During the term of this Agreement and for [     **     ] after
     the expiration or termination hereof (except in the case of termination by
     Company for material breach by AMEX hereunder), Company will not administer
     or directly offer Service (as it may exist at the time of such expiration
     or termination) or any similar service on behalf of or in conjunction with
     [       **           ] without the express written consent of AMEX. For
     purposes of this Section, a competitor of AMEX shall be deemed to be any
     [                                                **                       
                           ] In addition, AMEX agrees not to market the
     Enhancements with any third party provider during the Initial Term (as
     defined in Section 16) provided that the Company is not in material breach
     hereunder.

5.   INDEMNIFICATION AND HOLD HARMLESS: Each party (the "Indemnifying Party")
     shall indemnify and hold harmless the other party, its respective parent,
     subsidiaries and affiliates and their respective successors, assignees,
     directors, officers, agents and employees (each an "Indemnitee") from and
     against all third party liabilities, losses, damages, costs, expenses,
     actions, claims, demands, suits, and proceedings whatsoever, including
     losses incurred by them which result directly or indirectly from the
     willful or negligent acts or omissions of the Indemnifying Party, its
     employees, affiliates, agents or contractors in connection with the
     Indemnifying Party's obligations under this Agreement, or in connection
     with services performed or to be performed by such party pursuant to a
     Program or in connection with the Service (each a "Claim").

     Each party seeking indemnification under this Agreement shall give prompt
     notice to the Indemnifying Party along with its request for
     indemnification, of any Claim for which it is seeking indemnification. The
     parties understand and further agree that no settlement of an indemnified
     Claim shall be made by an Indemnitee without the concurrence of the


**   INDICATES CONFIDENTIAL TREATMENT REQUESTED.

                                       4

<PAGE>   5


     Indemnifying Party. The Indemnifying Party shall control the settlement or
     defense of any Claim; provided, however, that the Indemnitee may, at its
     cost, engage its own attorneys. The Indemnitee will fully cooperate with
     the Indemnifying Party to enable it to fulfill its obligations with respect
     to such Claim. The provisions of this Section shall survive the termination
     or expiration of this Agreement.

6.   PUBLICITY: No party shall refer to or identify the other party, such other
     party's parent, subsidiaries or affiliates, or the respective products or
     services of any of them, in advertising, promotional activity or publicity
     release relating to the Program without securing the prior written consent
     of such other party.

7.   CONFIDENTIALITY:

(a)  As used herein, "Confidential Data and Information" shall mean any
     information, data, or materials obtained by one party to this Agreement
     (the "Receiving Party") from, or disclosed to such party by, the other
     party (or, in the case of AMEX, disclosed to or by AMEX or any parent,
     subsidiary, or affiliated company related to AMEX) (the "Disclosing
     Party"), or the other party's customer or service establishment, which
     information, data, or materials relate to the aforesaid Program and their
     design and processes, or to the past, present, or future business
     activities of the Disclosing Party or any of its subsidiaries, affiliates,
     or clients, including methods, processes, telephone conversations,
     financial data, systems, customer names, account numbers, and other
     customer data, lists, apparatus, statistics, programs, and research and
     development, or related information of such entities, except such
     information as: (i) is previously known to the Receiving Party, free from
     any obligation to keep it confidential which Receiving Party can
     demonstrate through written records; (ii) is publicly disclosed either
     prior to or subsequent to the Receiving Party's receipt of such
     information; (iii) is lawfully obtained by the Receiving Party from a third
     party who, in making such disclosure, breaches no obligation of confidence;
     or (iv) is independently developed by the Receiving Party which Receiving
     Party can demonstrate through written records.

(b)  With respect to Company's access to customer files and related customer
     data ("Files"), Company specifically acknowledges the importance of
     maintaining the security and confidentiality of the Files, and agrees to
     take whatever steps are necessary to prevent the unauthorized transfer,
     disclosure to, or use of the Files by any person or entity not a party to
     this Agreement.

(c)  Neither party shall disclose, publish, release, transfer, or otherwise make
     available Confidential Data and Information of the other party in any form
     to, or for the use or benefit of, any person or entity without such party's
     prior written consent. Each party, however, shall be permitted to disclose
     relevant aspects of the other party's Confidential Data and Information
     only to its officers and its employees on a need to know basis to the
     extent that such disclosure is reasonably necessary for the performance of
     their duties and obligations under the Agreement; provided, that such party
     shall take all reasonable measures to ensure that Confidential Data and
     information of the other party is not disclosed or duplicated in
     contravention of the provisions of this Agreement by such officers and
     employees. Company 

                                       5

<PAGE>   6

     agrees to ensure that the terms and conditions of this Agreement are
     strictly adhered to by all of its employees and any third party
     representative. The obligations shall not restrict any disclosure by either
     party mandated by any applicable law, or by order of any court or
     government agency (provided that the disclosing party shall give prompt
     notice to the non-disclosing party of such order). In the event Company
     will have direct on-line access to American Express Customer data, Company
     also agrees to the terms of the AMEX Data Access Document attached hereto
     as Exhibit D-1 and will ensure that each Company employee with on-line
     access shall read, sign and comply with all Terminal Rules and Regulations
     set forth in Exhibit D-2 attached hereto.

(d)  Each party or its employees shall: (a) notify the other party promptly of
     any material unauthorized possession, use or knowledge, or attempt thereof,
     of the other party's Confidential Data and Information by any person or
     entity which may become known to such party and encourage its employees to
     do the same, (b) promptly furnish to the other party full details of the
     unauthorized possession, use or knowledge, or attempt thereof, and use
     reasonable efforts to investigate any unauthorized possession, use or
     knowledge, or attempt thereof, of Confidential Data and Information, (c)
     use reasonable efforts to cooperate with the other party in any litigation
     and investigation against third parties deemed necessary by the other party
     to protect its proprietary rights, and (d) promptly use all reasonable
     efforts to prevent a recurrence of any such unauthorized possession, use or
     knowledge of Confidential Data and Information. Each party shall bear the
     cost it incurs as a result of compliance with the requirements set forth in
     these paragraphs.

(e)  AMEX reserves the right to monitor access to Confidential Data and
     Information to prevent the improper or unauthorized use of such
     Confidential Data and Information. Such monitoring may include, but is not
     limited to, on-site inspection of Company's locations providing the Service
     for AMEX at any time during normal business hours, and inserting decoy
     names and addresses in any lists provided to Company. In addition, during
     the term of this Agreement, AMEX reserves the right to visit, unannounced,
     any of the locations used by Company that provides the Service for AMEX and
     verify security procedures during normal business hours.

(f)  Each party agrees that if there is any disclosure of the Confidential Data
     and Information by its employees or the employees of any third party, it
     will enforce for the other party's benefit through litigation, if
     necessary, all rights provided under law to compensate the former party for
     any damages arising out of such disclosure and to protect the former party
     from additional disclosure.

(g)  Each party agrees that if a party, its officers, employees or anyone
     obtaining access to the proprietary information of the other party by,
     through or under them, breached any provision of this Section, such other
     party would suffer irreparable harm and the total amount of monetary
     damages for any injury to such other party from any violation of this
     Section would be impossible to calculate and would therefore be an
     inadequate remedy. Accordingly, each party agrees that the other party
     shall be entitled to temporary and permanent injunctive relief against the
     breaching party, its officers or employees, and such other rights and
     remedies to 


                                       6

<PAGE>   7

     which such other party may be entitled to at law, in equity and under this
     Agreement for any violation of this Section.

(h)  Unless expressly limited herein, the provisions of this Section shall
     survive the termination or expiration of this Agreement.

8.   CUSTOMER SERVICE:

(a)  The Company shall provide a year-round Customer Service unit to support the
     Service. The Customer Service shall accord with the AMEX standards set
     forth on Exhibit B hereto as amended from time to time. The Company shall
     train and have available at all times sufficient staff to provide adequate
     Customer Service to Customers. The Company's Customer Service unit shall be
     dedicated primarily to the Service for AMEX Customers and other Company
     staff shall supplement this dedicated staff to handle unanticipated peaks
     in the Customer Service needs. In connection with Customer Service, the
     Company shall provide, at its sole cost and expense, an e-mail address
     dedicated for exclusive use by Customers (the "Dedicated E-Mail Address").

(b)  AMEX shall have the right, with reasonable notice, to monitor periodically
     the quality of the Company's obligations under this Section. AMEX alone
     shall have the right to determine whether the Company's performance
     hereunder is acceptable

9.   PHONE SYSTEM FOR THE SERVICE:

(a)  Company shall be responsible for establishing and maintaining, at its own
     expense, (i) a telephone number which is toll-free to Customers and (ii)
     one or more local telephone numbers (as reasonably determined by AMEX in
     consultation with Company) for Customers to use for collect calls to the
     Customer Service centers; provided, however, that AMEX shall be the
     customer of record for such telephone numbers and, as between AMEX and
     Company, AMEX shall have all rights in and to such telephone numbers.
     AMEX's status as customer of record and rights in and to all such telephone
     numbers shall survive the termination or expiration of this Agreement. AMEX
     shall have the right to inspect, at Company's offices during regular
     business hours, any and all telephone bills relating to these numbers.
     These telephone numbers shall be dedicated solely to the use by Customers
     for Customer Service fulfillment. Company personnel shall answer these
     telephone numbers in a manner specified by AMEX, and Company shall not
     publicize or use these numbers for any purpose not related to the Service
     without the express written consent of AMEX.

(b)  Company agrees that it will maintain its telecommunications systems in any
     manner reasonably requested by and reasonably acceptable to AMEX given that
     Company agrees with the recommendations. If Company does not agree with
     such recommendations, both AMEX and Company agree to review and explore
     other options. Company will bear all the costs of such upgrading with the
     exception of any consulting and services provided by AMEX through its
     telecommunications personnel, which shall be free of charge to Company.



                                       7

<PAGE>   8

(c)  AMEX shall consider any reasonable request and plan from Company to operate
     the phone system for the Service in any legitimate and technically feasible
     manner that takes advantage of any volume telecommunications user discounts
     available to AMEX. AMEX, however, shall be under no obligation to agree to
     such requests and plans, and may reject them with or without cause.

(d)  Additionally, all toll-free telephone numbers obtained by AMEX or used in
     connection with the performance of the Service by Company for AMEX
     hereunder shall be the sole and exclusive property of AMEX. Company hereby
     irrevocably assigns to AMEX all its rights, title and interest in and to
     such toll-free telephone numbers and will execute any and all documents
     necessary to transfer and/or evidence AMEX's ownership rights including,
     but not limited to, shared used agreements for the toll-free telephone
     numbers.

(e)  Upon termination or expiration of this Agreement, the Company shall
     transfer to AMEX the Company's rights in and to any of the telephone
     numbers described herein and the Dedicated E-Mail Address, including the
     rights to the use thereof, and shall assist AMEX in giving effect to such
     transfer.

10.  NOTICES: All notices, consents, requests, instructions, approvals, and
     other communications made, required or permitted hereunder (each herein, a
     "Notice") shall be given in writing and delivered to the receiving party to
     its respective address set forth below (i) by personal delivery to a
     responsible officer of such party, (ii) by certified or registered mail

(e)  Termination for Insolvency. Upon notice, either party may terminate this
     Agreement with immediate effect: (1) upon the institution by the other

     or regulation, such action shall not have been dismissed or all orders or
     proceedings thereunder affecting the operations or the business of the
     other party stayed, or if the stay of any such order or proceeding shall

     receiver or liquidator or similar official of the other party, or of all or
     any substantial part of the property of the other party, such appointment

     breach by AMEX) after such expiration or termination (the "Termination
     Assistance Period") (i) continue to provide the Service to the extent
     requested by AMEX at the rates and performance standards for such Service
     in effect under this Agreement immediately prior to such expiration or
     termination and (ii) provide such assistance as required by AMEX to
     transfer the Service to another vendor or to AMEX itself as set forth
     herein (the "Termination Assistance Services"). Upon expiration or
     termination of this Agreement for any reason, Company shall, at AMEX's
     direction, use its best efforts to transfer or assign the Service to
     another vendor selected by AMEX or to AMEX itself. After the expiration of
     the Termination Assistance Period, Company shall (1) answer questions
     regarding the Service on an as needed basis for [       **      ] (2)
     deliver to AMEX any remaining AMEX-owned reports and documentation still in
     Company's possession and (3) at AMEX's direction, destroy all AMEX data and
     information in its possession. Company shall provide the Termination
     Assistance Services [       **        ] except in the case of material
     breach by AMEX in which case AMEX shall be responsible for such costs. In
     the event that AMEX terminates this Agreement because of a breach by
     Company which is not timely cured, Company shall reimburse AMEX for
     reasonable out-of-pocket expenses incurred in connection with transferring
     the Service to another vendor or to AMEX itself. With AMEX's approval,
     which may not be unreasonably withheld, Company may negotiate transfer
     expenses on behalf of AMEX with another entity to insure the reasonableness
     of the expenses. With AMEX's approval, which may not be unreasonably

(g)  E-Mail Forwarding Obligations: The Company and AMEX acknowledge that it is
     in their respective best interests to keep all customers enrolled in the
     Service (or similar service) at the time of the termination or expiration
     of the Agreement -- whether the customers of AMEX or the Company - assigned
     to the Domain Name (such customers, the "Expiration Customers") for
     provision of the e-mail service expected by the Expiration Customers. The
     Company and AMEX further acknowledge that it is impracticable to attempt to
     assign the Expiration Customers to a new domain name for the provision of
     such service. Therefore, the Company and AMEX agree that upon the
     termination or expiration of the Agreement, the Company shall forward (the
     "Forwarding Function") all e-mail for Expiration Customers to an e-mail
     address designated by AMEX. The Company shall provide such Forwarding
     Function at a price it determines and stated in a unit charge for each
     e-mail to be forwarded (the "Unit Price") which price shall be effective
     for a one year period (the "Forwarding Period"). AMEX, in its sole
     discretion, may choose to accept the Unit Price offer and have the Company
     provide the Forwarding Function to the Expiration Customers or choose
     another vendor or itself to provide such service. In the event AMEX chooses
     another vendor or itself to provide the service, the Company shall [       
                                           **
                                              ] Company agrees to execute all
     documentation necessary to give effect to such transfer and to deliver all
     materials necessary for AMEX or its designee to operate the Domain Name and
     the Alternative Domain Name and to provide the Forwarding Function to the
     Expiration Customers. AMEX agrees to require such vendor or itself to
     provide the Forwarding Function with respect to the e-mail of Company's
     Expiration Customers to a domain name designated by the Company. In such
     event, Company shall pay the Unit Price to AMEX or 


**   INDICATES CONFIDENTIAL TREATMENT REQUESTED.

                                       12

     its designee in connection with the Forwarding Function. At the end of the
     Forwarding Period, the party which is performing the Forwarding Function
     shall determine a Unit Price for the following year, and the other party
     shall have the option to accept such Unit Price or to offer the Forwarding
     Function at such Unit Price. Such process shall be renewed at the end of
     each renewal Forwarding Period.

17.  AMEX SOFTWARE AND PROPRIETARY RIGHTS:

(a)  Grant of Non-Exclusive Access: AMEX hereby grants to Company solely for the
     purpose of providing the Service described herein, a non-exclusive,
     non-transferable right to have access to and (1) operate (i) the AMEX Card
     Member information proprietary software operated by AMEX prior to the
     Effective Date (or on an interim basis, AMEX will provide Company with a
     supplementary method of identification of Card Member information), and
     (ii) to the extent agreed upon by the parties, any AMEX Card member
     information proprietary software acquired or developed by AMEX, or on
     behalf of AMEX, in AMEX's name after the execution of this Agreement for
     use in connection with the Service ((i) and (ii) collectively, the "AMEX
     Proprietary Software"), (2) operate (A) the software licensed or leased by
     AMEX from a third party which was operated by AMEX prior to the date of
     execution of this Agreement, and (B) to the extent agreed upon by the
     parties, any software (other than Company Software) licensed or leased by
     AMEX from a third party after the execution of this Agreement ((A) and (B)
     collectively, the "AMEX Third Party Software"), and (3) use any related
     documentation in AMEX's possession on or after the date of execution of
     this Agreement (the "Documentation"). The AMEX Proprietary Software, the
     AMEX Third Party Software and the Documentation shall be collectively
     referred to as the "AMEX Software". As part of the Service, Company shall
     pay all license and maintenance fees for AMEX Third Party Software that
     Company elects to use to perform the Service (to the extent such fees are
     disclosed to Company in writing prior to its election to use such third
     party software and are deemed reasonable by Company). Company shall notify
     AMEX in advance in writing if it determines not to pay such license and
     maintenance fees. In the event that Company desires to use other comparable
     and compatible third party software and AMEX insists that Company use AMEX
     Third Party Software, AMEX shall pay the license and maintenance fees for
     such AMEX Third Party Software. Upon expiration of this Agreement or
     termination of this Agreement for any reason, the rights granted to Company
     in this Section shall terminate and immediately revert to AMEX and Company
     shall deliver to AMEX, at no cost to AMEX, a current copy of all of the
     AMEX Software in the form in use as of the date of such expiration or
     termination and Company shall destroy or erase all other copies of the AMEX
     Software in its possession.

(b)  AMEX's Rights. All inventions, methods, techniques, works of authorship,
     computer software, computer upgrades, computer programs, service providers,
     vendors information, training materials, telemarketing scripts, computer
     screens, reports, data, any other proprietary or confidential information
     made, created, developed or written and intellectual property ("Developed
     Materials") shall be deemed AMEX property if paid for or developed by AMEX
     (in no event shall the Marketing Dollars be used in the calculation of such
     payments). Furthermore, in the event Developed Materials (i) are paid for
     by AMEX such 



<PAGE>   14

     Developed Materials shall be deemed the sole property of AMEX or (ii) are
     jointly created by Company and AMEX and not paid for by AMEX, then such
     Developed Materials shall be deemed the joint property of AMEX and the
     Company. AMEX acknowledges that Company has developed, and will continue to
     develop during the term of this Agreement, valuable intellectual property
     used by Company in connection with the Service and that Company's ownership
     and protection of such property is essential to its competitive success.
     Accordingly, irrespective of any other provision of this Agreement, AMEX
     expressly agrees that Developed Materials paid for entirely by Company and
     created solely and independently by Company (or any agent of Company) shall
     be deemed the property of Company ("Company Property"). The Company
     Property and Developed Materials shall be deemed Confidential Data and
     Information and subject to the confidentiality provisions of this
     Agreement.

18.  SOURCE CODE ESCROW

     On the date hereof, Company shall deliver to an independent third party

     hereto and substantially in the form attached as Exhibit E ("Escrow
     Agreement"), a current and complete copy of the source code (the "Source
     Code") for the Domain Name and any other materials required to operate the
     Source Code (the "Escrow Materials").

     Within [        **       ] of the installation of any new update to the
     Service (or any other substantial modification to the Source Code, the
     Domain Name or the Service) or within [    **      ] of the last deposit
     hereunder, whichever is sooner, Company shall deliver to the Escrow Agent,
     for deposit in accordance with such Escrow Agreement, any and all changes
     to the Escrow Materials which correspond to changes, if any, made to the
     corresponding Escrow Material or shall notify Escrow Agent that no changes
     were made during the preceding period. All materials deposited hereunder
     shall be considered "Escrow Materials" as the term is used herein.

     In the event of (i) the Company's insolvency (as defined in Section 16(e))
     or (ii) the Company's material breach of the terms of this Agreement
     specifically because of its gross negligence or willful misconduct and such
     breach is not fully remedied within thirty (30) days of AMEX's notice to
     Company, then notwithstanding any other rights and remedies to which AMEX
     may be entitled, AMEX shall immediately have the right to obtain a copy of
     the Escrow Materials from the Escrow Agent upon written notice as provided
     in the Escrow Agreement for use in continued provision of the Service.

     new escrow agent (which will then become the "Escrow Agent" hereunder) and
     confirm such transfer in writing to AMEX and Company.

                         TERMINAL RULES AND REGULATIONS
- -------------------------------------------------------------------------------

Part of our mission is to make changes and adjustments to various Cardmember
accounts. This is done through the use of our computer system. The use of this
system is extremely critical. There are a few very specific rules and
regulations that go along with working with the computer system. These rules
must be followed in detail by every employee who is involved with the computer
system. Therefore, you are being shown the rules and regulations so that you
understand how the system works. It is very important that you understand and
comply with the following operating rules and regulations.

MAINTENANCE CHANGES TO CARDMEMBER ACCOUNTS.

As part of your job, you may be making address changes, maintenance changes, or
issuing replacement cards. You may also be making financial adjustments.

THE RULE IS: You are never to make any type of maintenance changes or financial
             adjustments to the following types of Card account:

1.   Your own American Express Account.

2.   A Card Account held by anyone you know outside of work.

3.   Any Account that you are not required to access as part of your job
     responsibility.

*Note - If in the normal course of business you need to make any type of
        maintenance or financial adjustment on an account held by another
        employee of American Express, immediately notify your Team Leader of the
        employee account you have just handled and the change or adjustment you
        have made.

USE OF YOUR PASSWORD AND IDENTIFICATION NUMBER

THE RULE IS: You are not to give your password to any person and you are not to
             use another employee's password or identification number.

This is for your own protection. Your password identifies you to the system. The
computer system tracks all entries that are made by the person who makes them.
If your password were to be use by anyone in such a manner that results in
errors or fraud, you would be held accountable for the error or fraud.


                                       30

THE RULE IS: You are to sign off when you leave your terminal and sign back on
             when you return to your terminal. This applies to time away from 
             your desk for breaks, lunch, meetings, etc.


MONITORING

All terminals are subject to monitoring and terminal monitoring may occur
simultaneously with telephone monitoring. In addition, you should understand
that all transactions in the system are recorded by the computer. Print-outs
listing all transactions by employee identification number and password are
monitored on a regular basis.

UNAUTHORIZED ACCESS/VIEWING OF ACCOUNTS

THE RULE IS: You are never to access or view the following types of Card
             accounts:

1.   Your own American Express Account.

2.   A Card Account held by anyone you know outside of work.

3.   Any Account that you are not required to access as part of your job
     responsibility.

       another employee of American Express immediately notify your Team Leader
       of the employee account you have just had to access. Otherwise, you are
       never to access or view a Card account held by another employee.

IMPORTANCE OF THE RULES AND REGULATIONS 

o    These rules are extremely important.
o    Any employee who willfully disregards these rules and regulations is
     subject to discipline, up to and including discharge from employment.

of April, 1997 (the "Effective Date"), by and among the USA.NET, Inc., a
Delaware corporation (referred to in this Agreement as the "Depositor"),
American Express Travel Related Services Company, Inc., a New York corporation
("AMEX") and Data Securities International, Inc., having an address at 101
Cambridge Street, Suite 310, Burlington, Massachusetts 01803-3741 ("Escrow
Agent").

Depositor and AMEX have entered into, inter alia, the Co-Marketing Program
Agreement, dated April ___, 1997 ("Marketing Agreement"), under which AMEX shall
market certain services (the "Service") of the Company to AMEX Customers. The
Marketing Agreement further provides for the escrow of materials relating to the
Service ("Escrow Materials") and this Agreement is entered into for the purpose
of effectuating such an escrow arrangement in connection with the Marketing
Agreement and the Services identified therein. Depositor and AMEX acknowledge
that Escrow Agent has no knowledge of the terms and conditions contained in the
Marketing Agreement and that Escrow Agent's only obligations shall be set forth
herein or in any other writing signed by Depositor, AMEX and Escrow Agent.

ARTICLE 1:  Deposit of Escrow Materials; Recordkeeping

1.1       On or before the delivery of the Service to AMEX Customers, Depositor
shall deliver to the Escrow Agent, for deposit under this Agreement, a current
and complete copy of the program source code, documentation and any other
materials required to operate the same to be deposited in escrow ("Escrow
Materials"). A specific description of the Escrow Materials required is set
forth on the attached Annex A, which is incorporated and made a part of this
Agreement. The Escrow Materials shall be subject to authentication by AMEX prior
to deposit thereof with the Escrow Agent. AMEX shall submit a certificate to
Escrow Agent which shall indicate that AMEX has authenticated the Escrow
Materials. Escrow Agent shall be entitled to rely upon such certificate as to
the matters stated therein.

1.2       Within [       **      ] of the installation of any new update to the
Service (or any other substantial modification to the source code, or the
Service) or within [     **     ] of the last deposit hereunder, whichever is
sooner, Depositor shall deliver to the Escrow Agent, for deposit in accordance
with this Agreement, any and all changes to the Escrow Materials which
correspond to changes, if any, made to the Service or shall notify Escrow Agent
that no changes were made during the preceding period. All materials deposited
hereunder shall be considered "Escrow Materials" as the term is used herein and
shall be deposited with a description thereof in the format of the form attached
hereto as Annex A.

1.3       The Escrow Materials may be removed and/or exchanged only on written
instructions signed by Depositor and AMEX, or as otherwise provided in this
Agreement.

ARTICLE 2:  Location of Escrow Materials

2.1      The Escrow Materials shall be administered by Escrow Agent from the 
location specified on Annex B and shall not be moved to any other location
without the express written consent of AMEX. Escrow Agent shall notify Depositor
in writing of any change in location.

2.2      AMEX shall have the right, at any time upon at least ten (10) days' 
written notice to Depositor and Escrow Agent, to select and designate a new
escrow agent to replace the Escrow Agent hereunder. Upon such notice and upon
payment of any outstanding fees due Escrow Agent, Escrow Agent shall completely,
safely and securely transfer the Escrow Materials to the new escrow agent (which
will then become the "Escrow Agent" hereunder) and confirm such transfer in
writing to AMEX and Depositor.

ARTICLE 3:  Verification of Escrow Materials

3.1      When Escrow Agent receives the Escrow Materials accompanied by a 
description of such materials in the form of Annex A attached hereto, Escrow
Agent will conduct a deposit inspection by visually matching the labeling of the
tangible media containing the Escrow Materials to the item descriptions and
quantity listed on Annex A.

3.2      Escrow Agent is entitled to be paid its standard fees and expenses
applicable to the services provided. Escrow Agent shall notify the party
responsible for payment of Escrow Agent's fees at least ninety (90) days prior
to any increase in fees. For any services not listed on Escrow Agent's standard
fee schedule attached hereto as Annex C, Escrow Agent will provide a quote prior
to rendering the service, if requested.

         3.2.1 Escrow Agent shall not be required to perform any services unless
         the payment for such services and any outstanding balances owed to
         Escrow Agent are paid in full. All other fees are due payable within
         thirty (30) days of receipt of invoice. If invoiced fees are not paid,
         Escrow Agent may terminate this Agreement; provided, however, that any
         non-payment of fees is remedied in accordance with the Material Breach
         provisions herein. If there is a discrepancy in fees owed to Escrow
         Agent, then the party responsible for payment and Escrow Agent shall
         agree to discuss this matter on a good faith basis.

3.3      In addition and upon AMEX's request, Escrow Agent shall be authorized
to perform any additional verification services which are available from Escrow
Agent from time to time specified on the attached Annex D, including, without
limitation, services necessary to verify the completeness, accuracy and
functionality of the Escrow Materials and to ensure that the Escrow Materials
conform and correspond to the Product furnished to AMEX under the Marketing
Agreement.

         3.3.1 Upon request, Escrow Agent will furnish AMEX with a current copy
         of the charges for additional verification services which are available
         from Escrow Agent 


                                       33

<PAGE>   34

         hereunder. AMEX shall be responsible for payment of any such charges
         directly to Escrow Agent and Depositor shall have no responsibility for
         same.

3.4      Escrow Agent shall report to AMEX in writing the results of all 
         verification services performed on Escrow Materials upon completion of
         same and shall send a copy to Depositor.

ARTICLE 4:  Release and Return of Escrow Materials

4.1      Upon receipt of a duly executed officer's certificate from AMEX 
certifying that a Triggering Event (as defined below) has occurred and
requesting the release of the Escrow Materials hereunder, Escrow Agent shall
release and deliver the Escrow Materials to AMEX or its designee set forth in
the officer's certificate. Such officer's certificate shall be delivered in
person or by registered or certified mail, return receipt requested. For
purposes of this Agreement, a "Triggering Event" shall be deemed to be (i) the
Depositor's insolvency (as defined in Section 16(e) of the Marketing Agreement)
or (ii) the Depositor's material breach of the terms of the Marketing Agreement
specifically because of its gross negligence or willful misconduct and such
breach is not fully remedied within thirty (30) days of AMEX's notice to
Depositor.

4.2      Escrow Agent shall be entitled to act in reliance upon any AMEX
instructions, instrument, or signature reasonably believed to be genuine and
shall assume that any AMEX officer giving any written notice or instruction,
which is consistent with this Agreement, has been duly authorized to do so on
behalf of AMEX. Similarly, Escrow Agent shall have no duty to inquire as to
whether AMEX or Depositor is in compliance with the provisions of the Marketing
Agreement relating to the release of Escrow Materials and shall have no
liability to Depositor or AMEX for relying on AMEX's notice.

4.3      If the Marketing Agreement has expired, been terminated or canceled 
and if AMEX has not notified Escrow Agent to release the Escrow Materials
hereunder as contemplated under Section 4.1 above, then Escrow Agent may return
or destroy the Escrow Materials at the request of Depositor; provided, however,
that Escrow Agent shall not return or destroy any such Escrow Materials unless
Escrow Agent has received written certification from AMEX that no event or
condition has occurred which would permit AMEX to obtain the release and
delivery of such Escrow Materials under this Agreement. Notwithstanding the
foregoing, if AMEX has not provided said written certification within thirty
(30) days from Escrow Agent's notice of termination, then at Escrow Agent's
option, Escrow Agent may return or destroy the Escrow Materials.

4.4      Each party shall designate an authorized individual as a contact for
the purposes set forth hereunder and individuals shall be specified on the
attached Annex E-1 and Annex E-2.

ARTICLE 5:  Confidentiality of Escrow Materials

5.1      Escrow Agent acknowledges that Depositor considers the Escrow Materials
to be confidential and trade secrets of Depositor, and Escrow Agent agrees that
unless Escrow Agent has obtained Depositor's written consent, Escrow Agent shall
keep the Escrow Materials confidential 



                                       34

<PAGE>   35

and prevent their disclosure to any person, firm or enterprise other than to
employees or representatives of Escrow Agent involved in the performance of
Escrow Agent's obligations under this Agreement, to employees and
representatives of Depositor, and to AMEX under the specific release provisions
specified in this Agreement.

5.2      Escrow Agent may copy Escrow Materials to the extent necessary to 
preserve and safely store the Escrow Materials, to perform the verification
services required and permitted under this Agreement, and to provide copies to
AMEX as and when permitted hereunder. On all such copies, Escrow Agent shall
reproduce any proprietary rights and/or confidentiality notices which were on
the Escrow Materials at the time of their deposit with Escrow Agent.

ARTICLE 6:  General

Payment: Escrow Agent may invoice AMEX for all fees and/or charges applicable
hereunder and AMEX agrees to pay each invoice properly rendered hereunder within
thirty (30) days after its receipt.

Liability: AMEX and Depositor agree that Escrow Agent is acting as an
independent agent and stakeholder hereunder and, except as regards the
obligations of Escrow Agent under Articles 4 and 5, shall not be held liable by
either party for the proper performance of its obligations under this Agreement.
Except as regards the obligations of the parties under Article 4 and 5, each
party shall be liable for and shall indemnify and hold each other harmless from
and against any loss or damage, including, without limitation, reasonable
attorneys' fees, other costs and/or expenses actually incurred by any other
party hereunder arising from the fault or negligence of such other party, its
officers, directors, employees, agents and/or representatives. Except as regards
liability under Article 4 and 5, none of the parties hereunder shall be liable
to any other party for any indirect, special or consequential damages arising
out of or in connection with this Agreement.

Termination: Upon the release, return, destruction or transfer of the Escrow
Materials as permitted hereunder or upon termination due to a material breach,
all further obligations and/or rights of Escrow Agent under this Agreement shall
terminate; provided, however Escrow Agent is not the party in breach.

Material Breach: In the event of any material breach of this Agreement by one
party, the other parties may (reserving cumulatively all other remedies and
rights under this Agreement and in law and in equity) terminate this Agreement,
by giving thirty (30) days' written notice thereof; provided, however, that any
such termination shall not be effective if the party in breach has cured the
breach of which it has been notified prior to the expiration of said thirty (30)
days.

Notices: Except as otherwise specifically provided, all notices shall be in
writing and delivered personally or mailed to the addresses of the parties set
forth at the beginning of this Agreement, to the attention of the undersigned at

Bankruptcy: AMEX, Depositor and Escrow Agent acknowledge that this Escrow
Agreement is an "agreement supplementary to" the Marketing Agreement as provided
in Section 365(n), Title 11 of the United States Code ("Bankruptcy Code"). If
Depositor, as a debtor in possession, or a trustee in bankruptcy appointed
pursuant to the Bankruptcy Code, rejects the Marketing Agreement or this
Agreement, then subject to any other rights AMEX may have, AMEX may elect to
retain its rights under the Marketing Agreement and this Agreement as provided
in the current Bankruptcy Code or any amendments and/or successor statutes.
Unless earlier notified by AMEX, Depositor and Escrow Agent, individually and
collectively, agree that unless they have received notice from AMEX that it does
not wish to make such election or exercise any such rights, neither Escrow Agent
nor Depositor shall interfere with the rights of AMEX in the Marketing Agreement
and/or this Agreement.

obligations hereunder without the written consent of each of the other parties
involved in this Agreement and any such attempted assignment shall be void;
provided however, that AMEX may require the transfer of Escrow Materials to a
new escrow agent (as permitted hereunder) and/or may assign this Agreement
and/or any of its rights and/or obligations hereunder upon written notice to
Depositor and Escrow Agent, to AMEX's parent, subsidiaries or affiliated company
without the consent of Depositor or Escrow Agent, provided that (i) AMEX has
provided the Depositor and Escrow Agent with at least 30 days prior written
notice, (ii) the assignee has the assets and facilities to carry out AMEX's
obligations under this Agreement and (iii) assignee is not a direct competitor
of the Depositor.

Severability: In the event any provisions of this Agreement are held to be
invalid, illegal or unenforceable, the remaining provisions of this Agreement
shall be unimpaired.

substantive laws of the State of New York without regard to conflict of law
principles.

Modification/Amendments: No modification, amendment, supplement to or waiver of
this Agreement or any of its provisions, whether by conduct or otherwise, shall
be binding unless made in writing and duly signed by the parties. A failure or
delay, by any party at any time, to enforce any of the provisions, or to
exercise any option, or to require performance, shall in no way be construed to
be a waiver or modification of this Agreement.

         This FIRST AMENDMENT TO CO-MARKETING PROGRAM AGREEMENT (the
"Amendment") is entered into this 17th day of October, 1997, by and between
USA.NET, Inc., a Delaware corporation (the "Company"), and American Express
Travel Related Services Company, Inc., a New York corporation ("AMEX").

         WHEREAS, the Company and AMEX entered into a Co-Marketing Program
Agreement, dated as of April 8, 1997 (the "Main Agreement"), pursuant to which
the Company agreed to provide e-mail services to certain of AMEX's current and
future holders of American Express(R) charge, credit or debit cards and certain
other individuals, and the Company and AMEX agreed to cooperatively promote such
services;

         WHEREAS, pursuant to Section 3(a) of the Main Agreement, the Company
and AMEX agreed that the financial terms of the Main Agreement could be amended
by written agreement of the parties; and

         WHEREAS, the parties desire to amend the financial terms of the Main
Agreement as more fully set forth below.

         NOW, THEREFORE, in consideration of the mutual promises and covenants
contained in this Agreement, the parties hereto agree as follows:

1.       DEFINITIONS: Unless otherwise defined herein, capitalized terms shall
have the meanings set forth in the Main Agreement.

2.       SECTION 1: Section 1(a) of the Main Agreement shall be amended to read
in full as follows:

         (a)      Description. AMEX hereby retains Company to, and Company
                  agrees to, provide Customers with an opportunity to enroll in
                  the e-mail service offered to the Company's customers from
                  time to time (the "Basic Service;" the Basic Service as
                  offered on the date hereof is more specifically described in
                  Exhibit A hereto), with changes and enhancements thereto as
                  developed from time to time specifically for AMEX and approved
                  by AMEX in its sole discretion, all in accordance with the
                  terms hereof. The changes and enhancements may include
                  services which are provided by AMEX or third parties, some of
                  which may have e-mail components and some of which may not.
                  These enhancements, including products which may be offered by
                  AMEX alone are more fully set forth in Section 3 below as
                  "Applications Products", "Content Products" and "AMEX
                  Products". The Applications Products and Content Products are
                  referred to collectively herein as the "Enhancements"; the
                  Basic Service as changed or enhanced by the Enhancements is
                  referred to herein as the "Service"). As compared with the
                  Basic Service, the Service will always have features,
                  including by way of example additional services, reduced
                  pricing or incentive offers that will

                  be exclusive to Customers. In the marketing and promotion of
                  the Service to Customers, AMEX shall determine which
                  Enhancements and features shall be included in the Service as
                  so marketed and promoted.

3.       SECTION 3: Section 3 of the Main Agreement shall be amended to read in
full as follows:

         3.   FINANCIAL ARRANGEMENT:

         (a)  The parties shall share Service Revenues (as defined below) with
              respect to the following products or services as set forth below:

              (i)   Basic Service and Applications Products. As used herein,
                    "Company Customers" shall mean Customers who were customers
                    of the Company prior to the distribution of any Promotional
                    Material and "Eligible Customers" shall mean all Customers
                    who are not Company Customers. AMEX shall be entitled to
                    receive or retain [        **        ], and the Company
                    shall be entitled to receive or retain [          **  
                        ], of the Service Revenues from the use by Customers of
                    the Basic Service and any application service enhancement
                    which is technically integrated with the Basic Service and
                    which is developed and offered by the Company either alone
                    or jointly with a third-party (the "Applications Products").
                    Examples of Applications Products include e-mail based [    
                                            **                    ] The parties
                    acknowledge and agree that AMEX intends to market and
                    promote a joint product with Premiere Technologies, Inc. and
                    the Company, the Connections(TM) Calling Card, which
                    contains e-mail convergence features and which would be
                    considered an Applications Product under this Agreement.
                    However, the parties agree that AMEX shall be entitled to
                    receive or retain [         **         ] and the Company
                    shall be entitled to receive or retain [        **        ],
                    of the Service Revenues received from Eligible Customers
                    with respect to the e-mail component of the Service provided
                    by the Connections(TM) Calling Card.

              (ii)  Content Products. "Content Products" are enhancements which
                    have an ongoing e-mail service component which generates
                    Service Revenue and which uses the Company's technology or
                    platform but which is not an integrated application. AMEX
                    shall be entitled to receive or retain [        **        ]
                    of the Service Revenues received from Eligible Customers for
                    any Content Products which it identifies and for which it
                    obtains the right to market and sell as part of a Program
                    (an "AMEX Content Product"), and the Company shall be
                    entitled to receive or retain [        **        ] of the
                    Service Revenues received from Eligible Customers for any
                    AMEX Content Products. An example of an AMEX Content Product
                    would include InfoBeat. The Company shall be entitled to
                    receive or retain [         **        ] of the Service
                    Revenues received from Eligible Customers for any Content
                    Products which it identifies and for

<PAGE>   52

                  which it obtains the right to market and sell as part of a
                  Program (a "Company Content Product"), and AMEX shall be
                  entitled to receive or retain [        **        ] of the
                  Service Revenues received from Eligible Customers for any
                  Company Content Products. An example of a Company Content
                  Product would include Quote.com.

         (b)  Payment. The party (the "Collecting Party") who is billing and
              collecting the Service Revenues with respect to a particular
              product or service shall remit to the other party (the "Receiving
              Party") its portion of the Service Revenues as set forth in
              subsection (a) above. The Collecting Party shall remit any
              payments due the Receiving Party within thirty (30) days after the
              end of each calendar month, along with back-up documentation
              reasonably acceptable to the Receiving Party showing the
              calculation of the amount so paid. Each party agrees to limit any
              direct commissions which it pays to a maximum of [        **    
                  ] of the Service Revenues which it receives from advertising
              sales.

         (c)  AMEX Products. If AMEX requests that any Program include
              advertisement for or promotion of products created by or on behalf
              of AMEX which do not generate an ongoing Service Revenue
              specifically attributable to an e-mail service component and which
              do not use the Company's technology or platform (the "AMEX
              Products") then AMEX shall pay the Company as follows: (i) if AMEX
              advertises or promotes the AMEX Products using advertisement on
              the Company's Basic Services (e.g., banner ads, direct e-mail or
              other web-based or e-mail advertisements) the Company's regular
              rates for such advertisement on its Basic Services, or (ii) if
              AMEX advertises or promotes the AMEX Products using other e-mail
              based promotion methods such as web pages or web links,
              reimbursement for all of its reasonable Costs (as defined below)
              associated with the sale of the AMEX Products (other than
              advertising rates) plus [        **        ] of such Costs (other
              than advertising rates). AMEX Products may include, without
              limitation, features such as American Express Cards, travel
              services, financial services, and calling cards (with the
              exclusion of e-mail convergence features). AMEX shall remit any
              payments due the Company pursuant to this subsection within ten
              (10) days after AMEX receives from the Company an invoice and
              back-up documentation reasonably acceptable to AMEX showing the
              calculation of the costs incurred.

         (d)  Service Revenues. As used in this Section 3, "Service Revenues"
              shall mean revenues generated by the use of the Service which:

              (i) includes (1) revenues generated from advertisement on the
                  Basic Service as used by Customers (which advertisement shall
                  accord with the AMEX advertisement policy set forth on Exhibit
                  C hereto, as amended from time to time), (2) fees charged to
                  Customers for enrollment in the Basic Service, Applications
                  Products or Content Products (the "Enrollment Fees"), which
                  Enrollment

                    Fees shall be determined by the parties hereto, and (3) any
                    other fees approved by the parties hereto from time to time;
                    and

              (ii)  excludes (1) applicable taxes, (2) fees or revenues 
                    generated by AMEX under any AMEX card acceptance agreement,
                    (3) revenues from Company Customers and (4) any reasonable
                    commissions for advertising sales directly or indirectly
                    relating to the Basic Service or any Enhancement (any
                    disagreement relating to the amount of third party
                    commissions shall be resolved by arbitration pursuant to
                    Section 18).

         (e)  Costs. "Costs" shall include the costs provided in Sections 2(d)
              and (e) hereof.

         (f)  Classification of Products, Services or Enhancements. At the
              request of either party, AMEX and the Company expressly agree to
              consider and negotiate in good faith the classification of any
              product, service or product enhancement under this Section 3 for
              purposes of determining the compensation to be paid in connection
              with its promotion and sale.

         (g)  Amendment of Financial Terms. AMEX and the Company expressly
              acknowledge that the financial terms stated herein may be amended
              as the parties may agree in writing.

         (h)  Domain Name Alternative Service Revenues. The parties hereto

              Customers that are provided the Service under the Domain Name
              Alternative (defined in Section 15) shall be subject to a Service
              Revenue share between the parties hereto as the parties shall
              reasonably agree.

         (i)  Acceptance Agreement. Company agrees that it will enter into an

2.       SERVICE OVERVIEW

         2.1 THE SERVICE. Netscape shall include Netcenter as part of
Netscape's Web Site. The Service will be included within Netcenter. The Service
shall be offered in the Local Language and targeted toward end users in the
Territory. The Service shall be Best-of-Breed Service, modeled after, yet
differentiated from, Participant Brand Service, in accordance with applicable
then current Netscape guidelines therefor. Netscape may revise such guidelines
therefor and the means whereby end users may access the Service, provided that
the prominence of the Service within Netcenter may not be materially reduced.
Netscape and Participant shall mutually agree upon the time frame for
implementing such changes, which time frame shall be no less than 30 days
(unless otherwise agreed by the parties). The Service shall be targeted at
users in North America who desire a free web-based email account on their own
(without a need to share) or a secondary email account for users to handle
their personal emails. During the Term, provided the Service substantially
conforms to the Best-of-Breed Service requirements, Netscape will not launch a
third party web-based email service, which is substantially similar to the
Service, targeted to customers located in the Territory in the Local Language
on Netscape's Web Site.

         2.2 SERVICE FRONT PAGE. Netscape shall host the Service Front Page,
unless otherwise agreed by the parties.

         2.3 SERVICE PAGES. The Service will: (i) be produced and managed by
Participant; (ii) have a "Netscape.com" domain name (or such other domain name
as Netscape may determine); and (iii) reside solely on Participant's servers.
All access to the Service shall be deemed to be via Netscape's Web Site, and
therefore shall be Netscape traffic. Every page of the Service shall be
co-branded by Netscape and Participant, and such co-branding shall appear above
the fold. Every page of the Service shall include navigational and branding
elements, which shall appear above the fold and offer end users navigational
controls within Netcenter. Netscape will determine, subject to Participant's
prior approval (which shall not be unreasonably withheld), the design/user
interface, promotions and links in all of the pages of Service, provided that
(i) all pages are consistent with the Netcenter look and feel; (ii) all pages
integrate key aspects of Netcenter navigation and functionality; (iii) branding
on all pages in the Service is consistent with the Netcenter branding scheme;
and (iv) all pages provide links to Netcenter including but not limited to a
Netcenter footer. Trailers (or successors thereto) at the bottom of outbound,
forwarded, POP3, and IMAP messages will also have a link to the Service,
including the full name of the Service. Any additional content for trailers (or
successors thereto) shall be mutually determined by Netscape and Participant.

         2.4 PROPRIETARY RIGHTS.

             2.4.1 Participant hereby grants Netscape a non-exclusive, royalty
free and fully paid up limited license under Participant's patents,
trademarks, copyrights, and trade secrets, whether presently owned or hereafter
acquired, to make, use, offer for sale, and sell products and services solely
in connection with the Service during the Term. All rights not expressly
granted to Netscape hereunder are reserved by Participant. Participant will
grant Netscape a non-exclusive, perpetual license after the end of the term to
any intellectual property in work product independently developed by
Participant for the Service at a price to be mutually determined in good faith.
Netscape acknowledges and agrees that the foregoing license grant conveys no
ownership interest and that, except for the license grant, Participant retains
all right, title and interest in its patents, trademarks, copyrights and trade
secrets.
 
             2.4.2 Netscape hereby grants Participant a non-exclusive, royalty
free and fully paid up limited license under Netscape's patents, copyrights,
and trade secrets, whether presently owned or hereafter acquired, to make, use,
offer for sale, and sell products and services solely in connection with the
Service during the Term. All rights not expressly granted to Participant
hereunder are reserved by Netscape. Participant acknowledges and 



                                       4.
<PAGE>   5

agrees that the foregoing license grant conveys no ownership interest and that,
except for the license grant, Netscape retains all right, title and interest in
its patents, copyrights and trade secrets.

             2.4.3 Participant shall not independently use the Service name 
without Netscape's prior written consent unless such use occurs in connection
with Participant's advertising, sales and promotional efforts on behalf of the
Service. If the Service name includes a co-branding component that is not
generic or descriptive, Participant may not use the Service name with the
Netscape name expunged, provided that nothing in this Section is intended to
prevent Participant from using its name or any of its corporate identifiers.

             2.4.4 Any intellectual property in work product resulting from 
co-development efforts under this Agreement shall be owned by Netscape subject
to a fully paid up, royalty free, perpetual license to Participant to make,
use, offer for sale and sell products and services that incorporate such
intellectual property, provided that Participant shall not make, use, offer for
sale or sell any products incorporating such intellectual property for a period
of 18 months after the termination or expiration of the Agreement (the
"Prohibition"), and such license shall survive termination of this Agreement.
For the purposes of this Agreement, "co-development" shall consist of (a) work,
even if performed solely by Participant, that primarily involves integration of
features and functionality with Netcenter functions and resources (such as the
member directory), unless such work consists of conforming to a published
Netscape API or specification; or (b) all other work where employees of each
party meet the statutory requirements under U.S. patent and copyright law (35
U.S.C. ss.16 and 17 U.S.C. ss.101 and ss.201, respectively) to be deemed
co-inventors or co-authors (including any work product consisting of conforming
to published Netscape APIs or specifications). Participant hereby assigns to
Netscape any and all of its rights, title and interests in any co-developed
work, and shall promptly deliver to Netscape all such co-developed work,
including but not limited to source code and all available documentation
therefor, in a form and manner to be specified by Netscape. Participant shall
cooperate with Netscape at Netscape's expense in perfecting any such rights,
including executing any necessary documentation.

             2.4.5 Neither party shall have the right to sublicense any of the 
other party's intellectual property, except that each party may sublicense any
intellectual property in work product that has been co-developed subject to
Section 2.4.4 and further provided that Participant complies with the
Prohibition in Section 2.4.4 above.

             2.4.6 In the event that third party license fees, royalties, or 
other payments are required for any technology in the Service, the parties
agree to negotiate in good faith a mutually acceptable sharing of such third
party payments.

             2.4.7 The parties agree that in the event of any alleged
infringement of third party proprietary rights by any component of the Service,
each party shall have the right, in its reasonable judgment, with no liability
to the other party, to suspend or discontinue or cause such suspension or
discontinuance of such allegedly infringing component, including the Service or
a portion thereof, until the alleged infringement claim is resolved.

3.       SERVICE IMPLEMENTATION

         3.1 PRODUCTION, TECHNOLOGY AND CONTENT DEVELOPMENT. Participant shall
be responsible for developing, producing and implementing the design, user
interface, promotions, links and functionality as determined by Netscape and
approved by Participant pursuant to Section 2.3. The parties agree that the
user interface may change on a fairly regular basis and Participant agrees that
it will respond to such changes within the time frame mutually agreed by the
parties. Participant shall use commercially reasonable efforts to employ
Netscape's technology in the Service, if available, rather than a technology,
which might compete with Netscape products or services, provided that such use
of Netscape's technology does not unduly burden the performance or production
of the Service. If Netscape commercially releases a client-server webmail
solution deemed by Netscape to be optimal for the Service, at Netscape's
request, Participant agrees to use such solution in the Service provided



                                       5.
<PAGE>   6
that the parties are able to agree on pricing therefor and further provided
that such solution is a "best of breed" solution (i.e., contains all of the
features and functionality of, and is of the same or superior quality to, other
available solutions).


On the Launch Date, the Service will consist of a free web-email service,
including Basic Features, and the Premium Services and Advanced Features
identified under Phase 1 in Exhibit D. Following the Launch Date and with
Netscape's prior approval, Participant will deploy the Premium Services and
Advanced Features identified under Phase 2 and Phase 3 in Exhibit D as set
forth therein, or as otherwise mutually agreed by the parties. Notwithstanding
Exhibit D, nothing in this Agreement obligates Netscape to approve any Advanced
Feature or Premium Service for inclusion in the Service; provided, however that
Netscape will not withhold its approval unreasonably.

         3.1.1 Netscape acknowledges and agrees that Participant's pre-existing
obligations to American Express Travel Related Services ("AMEX") requires that
Participant offer AMEX's customers any Advanced Features and Premium Services
available in the Participant Brand Services. Netscape further acknowledges and
agrees that Participant's obligations to AMEX require that Participant provide
AMEX's customers for the OEM service provided by Participant at URL:
www.amexmail.com. with at least one unique service or feature to distinguish
such AMEX service from others, provided that Participant does not unreasonably
withhold a service or feature deemed by Netscape to be critical to the Service.
Participant shall cooperate with Netscape to take all possible steps to prevent
any service or feature deemed by Netscape to be critical to the Service from
being excluded from the Service because of such pre-existing commitment. To
ensure Best-of-Breed Service, Participant will use commercially reasonable
efforts to develop or pursue third party relationships to provide new Advanced
Features and Premium Services which Participant will present to Netscape at
least on a quarterly basis. Participant agrees to offer such available new
Advanced Features and Premium Services to Netscape for implementation in the
Service for a period of 60 days (or such longer period if Netscape and
Participant so agree) in advance of offering such available new Advanced
Features and/or Premium Services to any Participant OEM partner other than
AMEX.

         3.1.2 Netscape must approve all functionalities, features,
enhancements and premium services before addition to the Service; provided,
however, Netscape will not withhold its approval unreasonably. With the
exception of fax services, Netscape grants Participant the right to provide all
Premium Services in Exhibit D. Netscape and Participant agree to review the
components of the Service to determine whether any functions, features,
enhancements or Premium Services should be added, removed, or replaced
considering changes in the general design or infrastructure of Netcenter,
technical feasibility, both parties' industry experience, cost of the Service
or Netcenter, impact on the Service's or Netcenter's performance, and both
parties' revenue generating opportunities. Participant will use best efforts to
integrate other Netcenter services, Netcenter control functionality, or Non
Affiliated Premium Services into the Service at Netscape's request in order to
provide a more consistent user experience for Netcenter members across the
Netcenter website, provided that these requests do not unreasonably and
materially adversely affect the Participant's costs or revenue generation
opportunities.

         3.1.3 Unless otherwise mutually agreed, the parties agree that
promotions and links in the Service shall be allocated as follows:

               (a) [**] of total ad banner inventory will be reserved for use at
Netscape's sole discretion to promote other Netcenter services or for
mutually-agreed barter ads of third party partners willing to promote the
Service;

               (b) Pop-up ads will be mutually agreed upon, with the initial
allocation of [**] to promote other Netcenter services and [**] to promote
Premium Services, collect additional information, or user surveys;

               (c) Advertising on Service Logout Pages will be sold and managed
by Participant;

**   INDICATES CONFIDENTIAL TREATMENT REQUESTED.

                                       6.
<PAGE>   7

               (d) New promotional opportunities will be mutually agreed upon;
and

               (e) Advertising portals on the vertical navigational frame on the
left hand side will be mutually agreed upon, with the initial allocation of [**
   ] for promotions of Premium Services and [  **  ] for advertising revenue
managed by Participant.

         3.1.4 Participant will manage, run, and sell slots in a direct
marketing content distribution program to be included in the Service sign-up
process. The direct marketing program will consist of two sections: (a) special
one-time promotions, which are not a subscription to a service or product and
(b) In-Box Direct for web email as it relates to the Service. The parties will
mutually agree on the quantity of (a) and (b). In addition, both (a) and (b)
shall be subject to Netscape's then-current privacy policy and general terms
and conditions of the In-Box Direct agreement, as such agreement may be amended
by Netscape from time to time upon 30 days prior notice to Participant. All use
and collection of End User Information shall be in compliance with Netscape's
privacy policy published at URL:
http://home.netscape.com/netcenter/privacy.html. With respect to (b), no
sponsors other than In-Box Direct partners may participate therein, and
Participant shall not distribute any ongoing email subscription content other
than In-Box Direct without Netscape's prior approval which approval will not be
unreasonably withheld. Netscape reserves the right to add, free of charge,
Netscape content or mutually selected partner content in the direct marketing
program. Participant will transmit to Netscape all end user data for In-Box
Direct per the format specified in the In-Box Direct agreement. Participant
will use commercially reasonable efforts to perform development work required
to ensure that web email subscription data is in sync with the standard In-Box
Direct program on a real time basis. All end user subscription management will
be handled through the In-Box Direct program unless mutually agreed otherwise.
Participant shall use commercially reasonable efforts to improve the process by
which end users of the Service receive In-Box Direct subscriptions. A link to
In-Box Direct shall be at the end of the sign-up process as well as in the user
interface for the Service. Both parties agree that the integration of In-Box
Direct with the Service may be postponed by mutual agreement.

         3.1.5 In addition, unless Best-of-Breed Service is breached, or the
parties mutually agree otherwise, Netscape agrees that:

              (a) At the Launch Date, the Service will have a link under the
Community section of the Netcenter homepage of Netscape's Web Site or
equivalent promotion if such page is redesigned;

              (b) At the Launch Date, the Service will have a link under the
Community section of Netcenter on the Netcenter index page or equivalent
promotion if such page is redesigned;

              (c) At the Launch Date, a listing will be given to the Service on
the Netcenter premium services page. This listing will most likely link to a
page in the Service, which describes the Premium Services. Netscape reserves
the right to change this listing or remove it in the future due to changes in
format or positioning of the Netcenter premium services page, provided that an
equivalent promotion is provided;

              (d) Netscape will include a one-time story on the Service in a
Netcenter newsletter;

              (e) During the first 2 weeks after the Launch Date, Netscape will
allocate [**] of remnant ad space on Netscape's Web Site, if any, to promote the
Service. For 6 weeks thereafter, Netscape will allocate [**] of remnant ad space
on Netscape's Web Site, if any, to the Service;

              (f) Netscape will run JavaScript messages targeted toward
Netcenter and non-Netcenter members to promote the Service on the home page of
Netscape's Web Site during the first 2 weeks after the Launch Date;


**   INDICATES CONFIDENTIAL TREATMENT REQUESTED.

                                       7.
<PAGE>   8
              (g) Within the first 3 months after the Launch Date, Netscape will
also provide one to two weeks of exposure for the Service in the Netscape
newsticker on the home page of Netscape's Web Site as well as flashes on the
corresponding newspage;

              (h) Netscape will promote the Service in the Netcenter flash
section of the home page of Netscape's Web Site at least once a week during the
6 weeks after the Launch Date;

              (i) Netscape will continue to promote the Service through the
remainder of the Term;

              (j) Within 6 months of the Launch Date, and subject to compliance
with all applicable laws relating to Netcenter contests and without Netscape
incurring additional compliance costs for such contests under this subsection,
Netscape will use commercially reasonable efforts to integrate new subscribers
of the Service into such contests in a manner that will incentivize users to
sign up for the Service and/or use the Service;

              (k) Netscape will use commercially reasonable efforts to offer a
Netcenter free email button to all In-Box Direct partners for inclusion in
outbound email newsletters at such partners' discretion. The In-Box Direct
program guidelines (which currently require a tag line at the top of the
mailing explaining to users who have mistakenly subscribed to In-Box Direct how
to unsubscribe) will be modified to require the In-Box Direct email messages to
contain language in the tag line to promote the Service;

              (l) Within 30 days after the Launch Date, the Service will replace
the current free email program available from In-Box Direct. A link to the
Service will appear on the welcome/what's new page of In-Box Direct. Netscape
reserves the right to discontinue this link if the format of the what's new
page or In-Box Direct changes. In such event, Netscape will replace the link
with another link in an equally prominent position elsewhere in Netcenter. A
link to the Service will also appear on the instructions and user FAQ page of
In-Box Direct. Some level of promotion will be given to the Service on the
thank-you page of the In-Box Direct sign up;

              (m) Netscape will promote the Service in pop-up promotions
[        **       ] impressions during the first 6 months following the Launch
Date unless Netscape discontinues pop-ups throughout Netcenter or as otherwise
agreed by the parties;

              (n) Within 6 months after the Launch Date, Netscape will include a
button for the Service on the personal toolbar in Netscape Communicator version
4.05, U.S. English language, upon general release on Netscape's Web Site.
Netscape will use commercially reasonable efforts to include an embedded email
message promoting the Service in a future release of the Netscape Communicator,
which message is visible to users after a new email profile is set up. If such
is not commercially reasonable, Netscape will provide an equivalent promotion;

              (o) Netscape may promote the Service in other avenues where
possible and appropriate;

              (p) Netscape will provide a program manager to work with
Participant to: establish development priorities; specify Advanced Features and
Premium Service offerings; evaluate performance and revenue generating
opportunities; set strategic direction; manage integration of the Service with
other Netcenter services; and develop and implement an advertising and
promotions plan. Netscape will also provide a production resource to assist in
the integration of Participant's email registration with Netcenter as well as
to provide direction on design and user interface functionality at least until
60 days after the Launch Date;

              (q) Users registering for Netcenter under Registration 2.0 will

the Service Registration. Netscape reserves the right to (i) change this
Service Registration process in future versions of Universal Registration; and
(ii) terminate the automatic assignment of Netcenter email addresses, provided
that Netscape will provide Participant 30 days advance notice of any material
change; and

               (r) Notwithstanding the foregoing subsections of this Section 
3.1.5, Netscape reserves the unilateral right to change any of these
allocations due to redesign of the home page of the Netscape Web Site or
changes in program allocation methodology provided that such promotions are
replaced with an equivalent promotion elsewhere on Netcenter.

         3.1.6 In addition, Participant agrees that:

               (a) Participant will dedicate a program manager to overall
program management of the Service. The program manager will be Participant's
central contact person to coordinate activities for Netscape. The program
manager will produce monthly reports/presentations to Netscape with
recommendations on how to improve revenue maximization, service performance,
customer service, and differentiate the Service. The presentation should also
include analyses of performance to date and competitive offerings. The program
manager will write and design content for the what's new page/section of the
Service subject to approval by Netscape. Participant will develop and implement
a Premium Service infrastructure and marketing plan to promote Premium Services
and Advanced Features, including but not limited to a what's new newsletter and
the what's new page. Participant will produce, manage, host and maintain the
Service as Best-of-Breed Service. This includes having sufficient staff and
managing creative, technical, and business staff to produce and operate the
Service as Best-of-Breed Service, including but not limited to advertising
sales/management, engineering, production, design, customer service, and
business development;

               (b) Participant will dedicate resources to ensure that the
Service is Best-of-Breed Service, and that the Basic Features, Advanced
Features and Premium Services approved by Netscape are developed and
implemented in a mutually agreed time frame. Participant will also ensure that
Netcenter services, Netcenter functionality, and Non Affiliated Premium
Services as described in Section 3.1.2 are integrated into the Service in a
mutually agreed time frame. Participant will allocate development resources,
which are sufficient to satisfy its obligations under this Agreement.
Participant will dedicate a quality assurance manager to develop, test and
monitor the Service to ensure that the Service is Best-of-Breed Service.
Netscape hereby grants Participant a right and license to use, solely for such
integration, the technology under Netscape's control that is necessary to
integrate any Non Affiliated Premium Service. In the event Netscape chooses a
vendor other than Participant or a Participant partner to provide a particular
Non Affiliated Premium Service, Netscape will pay Participant for the
reasonable cost of integration thereof with the Service provided such cost is
pre-approved by Netscape. The parties will discuss and mutually agree on the
revenue sharing for any Non Affiliated Premium Service as set forth in Exhibit
B. The parties acknowledge that providing a link in the web email interface
does not constitute "integration." "Integration" shall be mutually agreed by
the parties and generally applies to more resource intensive activities on the
part of Participant;

               (c) Participant will use commercially reasonable efforts to
support any Netscape initiatives to integrate the Service with current and
future releases of Netscape client software and the Netcenter Web site. If
Participant enters into a Netscape license agreement for the Netscape
Communicator source code and modifies such source code to better integrate the
Service into the Netscape Communicator user interface, Participant shall
promptly deliver such modified source code to Netscape so that Netscape may
promote these modifications or incorporate such changes into a future version
of the Netscape Communicator release by Netscape;

               (d) Upon Netscape's request, Participant will, at no additional
charge, commit the resources necessary to work with Netscape to complete a
feasibility/scoping study that looks at web email product improvement in a
long-term co-development of a scaleable full featured web email product. If the
parties agree to move forward following such feasibility study, the parties
agree to conduct further discussions detailing, under separate agreement, the
terms and conditions of the co-development effort therefor;


                                       9.
<PAGE>   10

               (e) Where not prohibited by an agreement in existence as of the
Effective Date between Participant and a third party, Netscape shall receive
more prominent (i.e. larger display, higher on page) promotion and positioning
with respect to any other directly competitive Internet client software
companies or online service companies similarly situated on the page;

               (f) Participant will offer to Netscape any functionality,
feature or enhancement integrated into the Participant's Brand Service within a
mutually agreed time frame;

               (g) Participant shall be responsible for the operations of the
Basic Features, Advanced Features, Premium Services offerings, allowing end
users to easily configure any Basic Features, Advanced Features, Premium
Service and/or Non Affiliated Premium Services, or manage their email account;

               (h) Participant shall promptly respond and resolve any spam
issues on the Service, including but not limited to using commercially
reasonable efforts to block spam; and

               (i) Netscape may develop additional Netcenter features and
programs to help promote sales and customer loyalty, and Participant shall
implement such services and features when they are developed, provided such
implementation is reasonable and standard for participants in Netcenter.

         3.2   ADVERTISING. Participant shall be responsible for selling
advertising and any other promotions within the Service Ad Inventory, subject
to Netscape's guidelines for advertising attached as Exhibit F. Participant
will consult with Netscape regarding the use of an external advertising sales
force in order to give Netscape the opportunity to assist Participant. If more
than [**] of the total Service Ad Inventory is sold via an external source, the
parties will mutually re-assess the advertising sales strategy. Advertising
services which Participant shall provide include site auditing, traffic
analysis, functionality and other advertising services. Participant will commit
resources to manage the advertising programs and sell the advertising inventory
in accordance with this Section 3.2. Ad management will include innovative
approaches to advertising in order to maximize revenue, track trial program
performances, and respond accordingly in a timely manner. Participant must be
able to serve targeted advertising to users of the Service. Participant shall
track, analyze, and report on ad performance on a monthly basis. Participant
shall design and develop banner ads subject to Netscape's approval, which
approval will not be unreasonably withheld, to promote the Service. The cost of
such promotion will be considered part of the cost of sales in calculating any
revenue sharing under this Agreement. The foregoing applies equally to the
development, management and sales of the direct marketing program described in
Section 3.1.4 above.

         3.3   CONTENT PROVIDER PARTICIPATION IN THE SERVICE. Participant shall
determine the guidelines by which Content Providers may participate in the
Service provided such guidelines comply with applicable then current Netscape
guidelines. Participant will be responsible for administering the Content
Provider application and complying with such Netscape guidelines. If a Content
Provider fails to come into compliance after receipt of notification, Netscape
shall direct Participant to reduce or remove the listing of a non-complying
Content Provider.

         3.4   TECHNICAL AND CUSTOMER SUPPORT BY PARTICIPANT. During the Term
and at no additional charge, Participant shall provide technical support
services for the Service to Netscape on a timely basis, appoint a technical
contact to whom Netscape may address all technical questions relating to the
Service, and use its best efforts to promptly remedy any material
malfunctioning of the Service in accordance with Best-of-Breed Service.
Participant shall be responsible for the maintenance and support of end users
of the Service in accordance with the Best-of-Breed Service. Participant shall
be solely responsible for the purchase, implementation, maintenance and support
of all software and hardware required to fulfill its obligations under the
Agreement. In addition, Participant shall make commercially reasonable efforts
to support Non Affiliated Premium Services for a mutually agreed fee or other
form of consideration.

home page of Participant's Web Site, and on any page on Participant's Web Site
which contains a virtual button or other text or graphic for any third party
Internet client or server software, software provider or online service. On any
page on which the Netscape Now button is displayed, the Netscape Now button
shall be at least equal in size and prominence to the virtual button, text or
graphic for any third party Internet client or server software, software
provider or online service. Netscape hereby grants Participant a nonexclusive
and nontransferable license to perform and display the Netscape Now button
directly in connection with fulfilling the foregoing obligation. Participant's
use of the Netscape Now button shall be in accordance with the guidelines of
the Netscape Now Program currently published at the URL
http://home.netscape.com/comprod/mirror/netscape_now_guidelines.html;

               5.1.4 Participant shall ensure that all web pages that are

online service that is directly competitive with Netscape's over Netscape's or
treat the provider of any such competitive software or online service as

to ensure that all web pages that are located one click away from any part of

positioning accorded any third-party Internet client or server software or
online service; and

               5.1.5 Participant's course of dealing with respect to other
services it may operate shall be governed by the terms of Section 5.2.

netscape.com domain name for the Service, and (ii)the treatment of the Service
as a fundamental part of the Netcenter service, until such time as Microsoft
fully publicly documents and makes available its operating systems programming
interfaces sufficiently to enable Netscape to make use of all of the facilities
and resources of those operating systems on a basis equal to that of Microsoft,
Participant shall:



                                      11.

               5.2.1 Within Participant's publicly accessible Web sites, other
services (including co-branded and OEM services to the extent Participant can
influence the third parties involved) and marketing materials, accord
Netscape's products and services a position of preference and prominence,
overall as well as on an element by element basis, at least as great as that
accorded any third-party Internet client or server software, software provider
or online service; and

               5.2.2 Not make content available solely to users of client
software or services other than Netscape's, or disfavor or disadvantage users

Internet client software or services.

               6.1.2 MONTHLY REVIEWS. Netscape and Participant agree to

review the revised business plan targets three months prior to the end of the

Confidential Information of both parties, provided, however that (i) Netscape
shall have the right to use the information contained in such reports in
Netscape's private and public reporting of access to the Service or Netscape's
Web Site; and (ii) Participant shall have the right to use the information

Participant or an underreporting in excess of [**] in traffic to the Service,
Participant shall pay for the audit plus any underpayment and make adjustments
based on the underreporting of traffic, if applicable. Netscape's audit rights

         6.5   RESEARCH. If either party conducts any research directly relating
to the Service, such research results shall be shared with the other on a
timely basis. If Participant or Netscape conducts a study on their respective

or termination of this Agreement, Participant shall promptly deliver to
Netscape any and all such end user data and information in a form and manner to
be specified by Netscape, and shall certify to Netscape that, except for the
copy delivered to Netscape, Participant has destroyed any and all such data and

         12.4   TERMINATION FEES. Netscape represents to Participant that it is
entering into this Agreement in reliance on Participant's representations and
agreement to implement the Service as set forth herein. In the event this
Agreement is terminated at any time during the Term by Participant due to

Participant shall, within 3 business days after termination of this Agreement,
pay Netscape, by cashier's check or wire transfer, at the option of Netscape, a
termination fee of [**        ] ("Netscape Termination Fee") as liquidated
damages. If some or all of the Netscape Termination Fee is not received by

fee on the unpaid portion the lesser of (a) 1% per month, or (ii) the maximum
rate allowed by law from the date the Termination Fee was required to be paid
until such unpaid portion is paid in full.

14.      GENERAL

         14.1   CONFIDENTIALITY. All disclosures in connection with this
Agreement as well as the contents of this Agreement and, subject to the terms
of Exhibit A, End User Information, shall be deemed Confidential Information


**   INDICATES CONFIDENTIAL TREATMENT REQUESTED.

                                      16.

and governed by the terms of the mutual confidential disclosure agreement
between the parties effective as of December 3, 1997, a copy of which is
attached hereto as Exhibit C

         14.2   INSURANCE. Participant, at its sole cost and expense, shall
secure and maintain adequate insurance coverage as is necessary, as a
reasonable prudent business person, for Participant to bear all of its
obligations under this Agreement. Maintenance of the foregoing insurance shall
in no way be interpreted as relieving Participant of any responsibility or
obligation whatsoever and Participant may acquire, at its own expense, such
additional insurance as Participant deems necessary. Participant assumes full
and complete liability for all injuries to, or death of, any person, or for any
damages to property arising from the acts or omissions of Participant.
Participant shall add Netscape as an additional insured under such coverage and
provide copies thereof within 30 days of the Effective Date or within 30 days
after any change in coverage. Participant's insurance shall be primary to any
other insurance Netscape may have.

         14.3   DISPUTE RESOLUTION. Any dispute hereunder will be negotiated
between the parties commencing upon written notice from one party to the other.
Settlement discussions and materials will be confidential and inadmissible in
any subsequent proceeding without both parties' consent. If the dispute is not
resolved by negotiation within 45 days following such notice, the parties will
refer the dispute to non-binding mediation conducted by JAMS/EndDispute. The
parties will share the costs of mediation. If the dispute is not resolved after
45 days of mediation, the parties will refer the dispute to binding arbitration
by JAMS/EndDispute. The location of the arbitration will be Santa Clara County,
California in the case of an arbitration which is initiated by Participant, and
Colorado Springs, Colorado in the case of an arbitration which is initiated by
Netscape. The results of any arbitration will be final and non-appeallable,
except that either party may petition any court of competent jurisdiction to
review any decision relating to intellectual property matters (including the
scope of license rights), vacating or modifying erroneous conclusions of law or
findings of fact not supported by substantial evidence. The arbitrator may
fashion any legal or equitable remedies except punitive or exemplary damages,
which both parties waive. The arbitrator will render a written decision, which
may be entered in and enforced by any court of competent jurisdiction, but
which will have no preclusive effect in other matters involving third parties.
The losing party will pay the costs of the arbitration and the reasonable legal
fees and expenses of the prevailing party, as determined by the arbitrator. The
parties will jointly pay arbitration costs pending a final allocation by the
arbitrator. At any point in the dispute resolution process, either party may
seek injunctive relief preserving the status quo pending the outcome of that
process. Except as noted, the parties waive any right to judicial process.
California law, without regard to its conflict-of-law provisions, will govern
this Agreement. The U.S. Arbitration Act and JAMS/EndDispute rules will govern
the arbitration process. Absent fraudulent concealment, neither party may raise
a claim more than 3 years after it arises or any shorter period provided by
applicable statutes of limitations.

         14.4   NOTICES. All notices required or permitted hereunder shall be
given in writing in the English language and shall be addressed to the
respective parties as set forth on the Cover Sheet and shall either be (i)
personally delivered or (ii) transmitted by internationally-recognized private
express courier and shall be deemed to have been given on the date of receipt
if delivered personally, or 2 days after deposit with express courier. Either
party may change its address for purposes hereof by written notice to the other
in accordance with the provisions of this Subsection.

         14.5   MISCELLANEOUS. (a) Neither party's waiver of a breach or delay
or omission to exercise any right or remedy shall be construed as a waiver of
any subsequent breach or as a waiver of such right or remedy. (b) This
Agreement may be amended only by a writing signed by both parties. (c) [

any delay or failure in performance hereunder, except the payment of
(undisputed) monies, caused by reason of any occurrence or contingency beyond

day-to-day basis for the period of time equal to that of the underlying cause
of the delay. (i) This Agreement, including the Cover Sheet and Exhibits
hereto, constitutes the entire agreement between the parties concerning the
subject matter hereof and supersedes all prior and contemporaneous agreements,

the parties shall mutually agree.

NETCENTER CONSIDERATIONS. All third party programs including but not limited to
Premium Services and Non-Affiliated Premium Services participating in the
Service within Netcenter shall register users with Netcenter when the user

provider.

UNSUBSCRIBE. All outbound communications from the Participant to end users
registered for the Service, except special one-time promotions as defined in
Section 3.1.3, must offer the end user the option of "unsubscribing" from the

addition, the Participant must offer the end user a central and consistent
interface to "unsubscribe", cancel, renew, or sign up for any Premium Services,
Non-Affiliated Premium Services, and mutually selected advanced features
offered in the Service. This central account management interface must be
mutually designed by the parties. Participant must also offer end users a
streamlined option for "unsubscribing" completely from the Service or

DEFINITION OF "NET REVENUE." Net Revenue is defined as total gross revenues,
specifically excluding taxes, from the sum of:

               (a) advertising net revenue (gross advertising revenues less
reasonable fees and commissions, including but not limited to internal
commissions, [        **       ];

               (b) Sponsorships (gross sponsorship fees less commissions,
including but not limited to internal commissions, [        **       ];

               (c) Premium Services; and

               (d) special one-time offers net revenue (gross promotional
revenues less reasonable fees and commissions, including but not limited to
internal commissions, [        **       ];


and in the case of each of (a) - (d) above, less mutually agreed deductions
such as bad debt, returns, billing costs and/or cost of sales, provided that
the total combined deductions against such revenue [          **           ].
If it appears that the deductions for the items above [        **          ],
Participant shall consult with Netscape regarding which party should sell to
the advertiser or sponsor in question.

         1.2   With respect to revenue from In-Box Direct promotions included
in the Service Registration process, the parties will split such revenue
[             **               ], after subtracting mutually agreed deductions
such as bad debt, returns, and/or cost of sales.

         1.3   With respect to Non Affiliated Premium Services, the parties
shall negotiate a revenue sharing agreement prior to integrating such service.
In addition, Netscape shall reimburse Participant for the reasonable cost of
integration relating thereto as set forth under Section 3.1.6(b). The parties
agree that if Participant only includes a link in the Service to the Non
Affiliated Premium Service, Netscape will not pay any costs or share any
revenue with Participant for such Non Affiliated Premium Service. If
Participant does perform integration work as defined in Section 3.1.6(b) for a
Non Affiliated Premium Service (other than for In Box Direct, for which
Netscape shall not pay any integration costs or share revenue), Netscape will
reimburse Participant for reasonable integration costs [                      
             **                           ]. If Participant performs such
integration work and

performs other substantial services (such as integrated billing) with respect
to a Non Affiliated premium Service, Netscape will reimburse Participant for
the reasonable costs thereof and the parties will negotiate the revenue-sharing
terms on a case-by-case basis.

         1.4   The parties acknowledge that there may be additional revenue
opportunities under this Agreement, and the parties will mutually agree to the
revenue split on a case by case basis.

2.       TIMING OF PAYMENT. Within [  ** ] after the end of each Netscape
         fiscal quarter during the Term of this Agreement, each paying party
         shall deliver to the receiving party a report describing in detail the
         calculation of gross revenue actually collected and net revenue
         actually collected for such fiscal quarter, and shall pay to the
         receiving party such party's portion of such net revenue actually
         collected calculated as described above, with no right of set-off. The
         Netscape fiscal quarter shall be based on a fiscal year ending October
         31.

3.       POST-TERM PAYMENTS OF BAD DEBT. After termination or expiration of
         this Agreement, each paying party shall pay to the receiving party all
         amounts received by the paying party previously charged by the paying
         party as "bad debt" ("Bad Debt Payments") and deducted from gross
         revenue under Section 1 above to the extent such deducted amounts have
         not already been paid to the receiving party. Within 30 days of the
         receipt of any Bad Debt Payment, the paying party shall deliver such
         payment to the receiving party. This Section shall survive expiration
         or termination of this Agreement.

4.       CURRENCY AND TAXES. All amounts payable hereunder are denominated in
         U.S. Dollars, and all amounts payable hereunder shall be remitted in
         U.S. Dollars. Any portion of any payment due which has not been paid
         during the applicable time set forth herein shall bear interest at the
         lesser of (i) 1% per month or (ii) the maximum rate allowed by law.
         All payments due hereunder are exclusive of any applicable taxes. The
         collecting party shall be responsible for all applicable national,
         state and local taxes, value added or sales taxes, exchange, interest,
         banking, collection and other charges and levies and assessments
         pertaining to payments other than U.S. taxes based on Netscape's net
         income. If the collecting party is required by law to make any
         deduction or to withhold from any sum payable to the other party
         hereunder, the collecting party shall effect such deduction or
         withholding, remit such amounts to the appropriate taxing authorities

                    MUTUAL CONFIDENTIAL DISCLOSURE AGREEMENT

This Mutual Confidential Disclosure Agreement ("Agreement") is entered into
between Netscape Communications Corporation ("Netscape") and USA.Net
("Company"), and is effective as of the date of execution by Netscape
("Effective Date"). Each party (the "Receiving Party") understands that the
other party (the "Disclosing Party") may disclose certain Confidential
Information (as defined in Section 1 below) under this Agreement. Netscape and
Company agree as follows:

1.       DEFINITION. "Confidential Information" shall mean (i) all information
         disclosed in tangible form by the Disclosing Party and marked
         "confidential" or "proprietary", and (ii) all information disclosed
         orally or otherwise in intangible form by the Disclosing Party and
         designated as confidential or proprietary at the time of disclosure.
         Confidential Information may include, without limitation, computer
         programs, code, algorithms, names and expertise of employees and
         consultants, know-how, formulas, processes, ideas, inventions (whether
         patentable or not), schematics and other technical, business, financial
         and product development plans, forecasts, strategies and information.

2.       PURPOSE. The Receiving Party shall use the Confidential Information
         only for the following purposes:

         a)       To evaluate whether to enter into a contemplated business
                  transaction; and

         b)       if Netscape and Company enter into such contemplated business
                  transaction, to fulfill each party's commitments under the
                  agreement for such business transaction.

3.       CONFIDENTIALITY OBLIGATION. The Receiving Party agrees to protect the
         Confidential Information by using the same degree of care, but not less
         than a reasonable degree of care, to prevent the unauthorized use,
         dissemination or publication of the Confidential Information as the
         Receiving Party uses to protect its own confidential or proprietary
         information of a like nature. The Receiving Party shall limit the use
         of and access to the Disclosing Party's Confidential Information to the
         Receiving Party's employees or independent contractors who need to know
         such Confidential Information for the purposes set forth in Section 2
         above and who have entered into binding obligations of confidentiality
         substantially similar to the obligations set forth herein.

4.       TERM. The Receiving Party's obligations to protect Confidential
         Information hereunder shall expire 3 years from the date of each such
         disclosure of Confidential Information, except when such Confidential
         Information disclosed by the Disclosing Party is source code, in which
         case the Receiving Party's obligations to protect such Confidential
         Information shall be perpetual.

5.       EXCLUSIONS. Confidential Information as defined in Section 1 above
         shall not include Confidential Information that: (i) is or becomes a
         matter of public knowledge through no fault of the Receiving Party; or
         (ii) was in the Receiving Party's possession or known by it prior to
         receipt from the Disclosing Party; or (iii) was rightfully disclosed to
         the Receiving Party by another person


                                     24.
<PAGE>   25

         without restriction; or (iv) is independently developed by the
         Receiving Party without access to such Confidential Information. The
         Receiving Party may disclose Confidential Information pursuant to any
         statutory or regulatory authority or court order, provided the
         Disclosing Party is given prompt written notice of such requirement and
         the scope of such disclosure is limited to the extent possible.

6.       INDEPENDENT DEVELOPMENT. The terms of confidentiality under this
         Agreement shall not be construed to limit either party's right to
         independently develop or acquire products without use of the other
         party's Confidential Information. Further, Confidential Information as
         defined in Section 1 above shall not include the Residuals resulting
         from access to such Confidential Information. The term "Residuals"
         means information in intangible form which may be retained in the
         unaided memories of Receiving Party's employees or independent
         contractors who have had access to the information. An employee's or
         contractor's memory will be considered to be unaided if the employee
         has not intentionally memorized the Confidential Information for the
         purpose of retaining and subsequently using or disclosing it. Neither
         party shall have any obligation to limit or restrict the assignment of
         such persons or to pay royalties for any work resulting from the use of
         Residuals. However, the foregoing shall not be deemed to grant to
         either party a license under the other party's copyrights or patents.

7.       RETURN OF CONFIDENTIAL INFORMATION. Upon written request by the
         Disclosing Party at any time, the Receiving Party shall: (i) turn over
         to the Disclosing Party all Confidential Information of the Disclosing
         Party, all documents or media containing the Confidential Information,
         and any and all copies or extracts thereof, or (ii) destroy the
         Confidential Information, and any and all copies or extracts thereof,
         and provide the Disclosing Party with written certification of such
         destruction signed by an authorized representative of the Receiving
         Party.

8.       EQUITABLE RELIEF. The Receiving Party acknowledges and agrees that due
         to the unique nature of the Disclosing Party's Confidential
         Information, there may be no adequate remedy at law for any breach of
         its obligations. The Receiving Party further acknowledges that any such
         breach may allow the Receiving Party or third parties to unfairly
         compete with the Disclosing Party resulting in irreparable harm to the
         Disclosing Party and, therefore, that upon any such breach or any
         threat thereof, the Disclosing Party shall be entitled to seek
         appropriate equitable relief in addition to whatever remedies it may
         have at law. The Receiving Party will notify the Disclosing Party in
         writing immediately upon the occurrence of any such unauthorized
         release or other breach.

9.       INTELLECTUAL PROPERTY RIGHTS. Neither party acquires any intellectual
         property rights or any other rights under this Agreement or through any
         disclosure hereunder, except the limited right to use the Confidential
         Information in accordance with this Agreement.

10.      WARRANTY. The Confidential Information disclosed under this Agreement
         is delivered "AS IS," and all representations or warranties, whether
         express or implied, including warranties or conditions for fitness for
         a particular purpose, merchantability, title and noninfringement, are
         hereby disclaimed.

11.      NETSCAPE SUBSIDIARIES. Netscape's wholly owned subsidiaries, by signing
         this Agreement on behalf of Netscape and returning a fully executed
         original or copy to the Netscape Legal Department, shall be entitled to
         disclose Netscape's Confidential Information and receive Company's
         Confidential Information on behalf of Netscape under this Agreement,
         provided such subsidiaries comply with the terms and conditions of this
         Agreement and further provided such disclosures or receipt of
         Confidential Information are governed by the terms and conditions of
         this Agreement.

           -->

4.   If you offer the option of customizing the service, then the Welcome Letter
will also serve as a Registration Letter. The Welcome/Registration letter must
give the user the opportunity to select customized features of the service, such
as language, frequency of delivery, topics of interest, and authors.

o   You must have a default for all customized publications so that a subscriber
who fails to take action on the Welcome Letter will at least receive some
content from you.

o   You may not ask IBD subscribers any questions in your Welcome/Registration
Letter which would have already been answered in the IBD registration process
and forwarded to you through the Netscape daily datafeeds.

5. All mailings must provide two ways to unsubscribe: 1) direct from the
mailing; and 2) a link back to In-Box Direct with instructions on how to
unsubscribe. SEE SECTION II.C. for more information.

6. All mailings must include the current IBD branding GIF per Netscape's
specifications as well as the Netscape Now button.

7. You must place the following tag line at the bottom of each mailing to In-Box
Direct subscribers: "This mailing is best viewed through Netscape Communicator".

F. GOODBYE/UNSUBSCRIBE MESSAGE

1. You must send the program manager a URL for your Goodbye/Unsubscribe mailing
by the push deadline.

2. The Goodbye/Unsubscribe Message serves as a confirmation to end users that
their cancellation requests have been received and processed. The
Goodbye/Unsubscribe Message must be written in HTML, but have a section in
ASCII.

3. Non-English services must include an unsubscribe confirmation in both English
as well as the language of origin.

4. You must send the Goodbye/Unsubscribe Message to all IBD users who
unsubscribe from your service. This includes users who unsubscribe direct from
the mailing, users who unsubscribe through In-Box Direct, and users who
unsubscribe by sending a special request to IBD feedback (handled by IBD
customer service).

5. You must send Goodbye/Unsubscribe Message within twenty-four hours of
receiving notification from the subscriber or Netscape.

6. It is recommended, although not required, that you include an exit survey as
part of your unsubscribe process or goodbye message. This will enable you to
better understand retention issues and revise your service accordingly. Examples
of unsubscribe surveys are available on request from the program manager.

G. SAMPLE PAGE

1.   You must send the sample page URL to the program manager by the push
deadline. After the push is executed, all sample pages will be hosted by
Netscape on the Netscape site.

2.   It is your responsibility to test thoroughly the sample pages and to verify
compliance with all sample page specifications. You understand that inability to
meet sample page specifications by the push deadline, may result in a delay of
at least one month in the commencement of program participation.

o   The Sample Page Checker tool at the following URL will assist you in meeting
these specifications:
HTTP://HOME.NETSCAPE.COM/ESCAPES/IBD/SAMPLE_CHECK.HTML

o   Sample pages must be tested on Win95, Windows 3.1, Macintosh, and UNIX. Note
that some sample pages that appear fine on a Macintosh will bleed out of the box
when viewed with Windows 95.

3.   The sample page can be no more than three pages. It is suggested that you 
use one page to explain the features and benefits of the service and one page to
show the users an example of an actual mailing.

4.   The sample page must be sized to fit within 640 x 400 pixels. You must test
the size of the sample on a PC WINDOWS 95 system. The Sample Page Checker URL
will enable you to test the size and verify compliance with the required
dimensions.

5.   If multiple pages (maximum 3) are used, all pages must be linked together.
"MORE" and "BACK" links must be implemented. "Back" links ("Back" to the
previous sample page) must be included on all pages, except the first page.

6.   A "Return to In-Box Direct" button must be located in the upper right 
region of each page. The preferred layout can be seen at The Sample Page Example
which can be accessed from the IN-BOX DIRECT SAMPLE PAGE GUIDELINES page at
HTTP://HOME.NETSCAPE.COM/ESCAPES/IBD/GUIDELINES.HTML.

7.   On all pages, clicking on either the "Return to In-Box Direct" words or the
In-Box Direct GIF, must close the sample page window and bring the user back to
the In-Box Direct site.

o   NOTE: This sample page window operation requires specific JavaScript. The
return button GIF and JavaScript are provided by Netscape. Refer to The Sample
Page Template (HTTP://HOME.NETSCAPE.COM/ESCAPES/IBD/SOURCE.TXT) which provides
the necessary HTML, GIF, and JavaScript.

8.   The sample page may not contain any of the following: outside links, menu
bar, button bar, location entry field, scroll bars, or a resize handle.

9.   Sample page must not exceed 25 kilobytes (this includes the HTML file and 
all images).

10.  Link color must change from blue to red after execution.

II. SERVICE STANDARDS/ONGOING PROVIDER RESPONSIBILITIES

You will make every reasonable effort to work with Netscape to provide the
highest quality service and experience for the end user.



                                       4.
<PAGE>   42

A. HTML MAIL REQUIREMENTS

1.  You are responsible for creating and producing a free HTML publication as
approved by the IBD Program Manager, and mailing all content directly to the
subscriber on a regular basis.

2.  You must comply to the frequency standards you have established for yourself
and communicated to the subscriber in the description of the service, e.g., if
listed as a daily service in In-Box Direct, mailings must be sent out to
subscribers daily.

3.  You must contact the subscribers within forty-eight hours of receiving
subscription information with either a Welcome Letter or an actual mailing.

4.  You must contact the subscribers within twenty-four hours of receiving an
unsubscribe request with a written confirmation of the unsubscribe,

5.  You must follow the instructions immediately below to insure that the mail
is properly displayed by Netscape Messenger or any other mail clients that read
HTML format mail.

o   Include CONTENT-TYPE: TEXT/HTML as the header (first line) of the content to
be delivered. The header must be followed by one blank line.

6.  To facilitate user filtering, the subject (header) field of each IBD email
sent by you must begin with a designated prefix (IBD). For example: IBD- People
Daily November 13.

This will enable IBD users to filter for IBD mail and to store such mail in a
separate email folder, thereby reducing the tendency to unsubscribe.

7.   All IBD mailings must contain the following components:

o    Unsubscribe functionality as defined in the Unsubscribe section in Section
II.c.

o    IBD/ Netscape branding as defined in the branding section in Section III.

o    IBD indicator in subject field as described above.

8.   You must make every reasonable effort to facilitate the collection of user
feedback relative to your service. A hot button or an email address such as,
[email protected], must be included on all IBD mailings. Note: Customer feedback
must only be collected if you have the resources to support it.

B. DATABASE / LIST SERVER REQUIREMENTS

1.   You are responsible for setting up and managing your own subscriber 
database and mailing list from the data provided by Netscape.

2.   Your system must be able to receive and process data sent from Netscape 
once a day, 7 days a week, between 2:30 a.m. to 6:30 a.m. PST.

o   Netscape provides, on a daily basis, a data feed which contains information
to CREATE new subscriptions, DELETE unsubscribes and UPDATE (changes to)
subscriptions. Your system must be able to recognize status codes (e.g., create,
update, delete), and process the record accordingly. Updates must be processed
within twenty-four hours of receipt.


                                       5.
<PAGE>   43


o   Data is always transmitted on the morning after it is collected. For 
example, if today is 12/24/97, the daily feed received by 4 a.m. today, is
12/23/97's registration information. Thus, the subject field will read "IBD
Registration for 12/23/97".

3.   You must structure your subscription fulfillment processes such that
duplicate email addresses are automatically caught to prevent subscribers from
receiving multiple copies of a mailing. Duplicates in the name field must be
allowed, because individuals may have the same name or individuals may choose to
subscribe from multiple email addresses, that is, office and personal email
addresses.

4.   Your list servers must be configured so that subscribers on the list CANNOT
send to the list. Only you should be able to 1) send to the list, and 2) view
the members of the list.

5.   You must also ensure that the reply-to and from fields in the email from 
the list server point to appropriate email addresses. For example, the reply-to
might be directed to an alias for whoever is maintaining the list, so that the
maintainer of the list can respond to any queries.

6.   Ideally, the list server should send one email out at a time 
(personalized). If not, it must load multiple subscriber names into the BCC
field (blind carbon copy), NOT the TO or CC fields.

7.   You must build a mechanism to monitor that a daily data feed from Netscape
was received. You must notify Netscape immediately if there are any problems
with the data feed. (Currently, problems can be sent to [email protected] with
a copy to [email protected]).

8.   You should use a database with send mail capability or a listserve product
to distribute your HTML email. See below for a list of products, outsources, and
prices to find out more information.

o    Majordomo - (freeware) at http://www.greatcircle.com/majordomo

o    Listserv: http://www.lsoft.com

o    UNIX send mail command

o    Email Publishing, Inc. is an email broadcasting outsourcing service which
has assisted several IBD providers in the past. Email Publishing can set up and
manage the database, develop the sample page, and even create templates for
ongoing HTML mailings. If interested, contact Andrew Currie, at (303) 440-7550
or [email protected]. For a special rate, you must identify yourself as an
In-Box Direct participant.

o    The names of several Internet service providers that manage mailing lists
are posted at http://www.catalog.com/vivian/mailing-list-providers.html

C. "UNSUBSCRIBE" REQUIREMENTS

1.   You must support three forms of unsubscribe functionality in every outbound
mailing including the Welcome Letter, with the exception of the unsubscribe
confirmation notice. The first two options must be clearly visible in the HTML
content and communicated to the end user. The last of these options must only be
visible to ASCII users and not HTML readers.

o    Option 1:  Unsubscribe functionality from the outbound mailing directly to
the you.


                                       6.
<PAGE>   44


o   Option 2: A link to In-Box Direct along with an explanation of how the user
can unsubscribe by unchecking the box next to the service offering on the
selections page in In-Box Direct. (Note that this link must be separate from the
IBD branding link.)

o   Option 3: Instructions for ASCII users regarding how to unsubscribe if they
have signed up for this mailing in error. The instruction message must be placed
after the /Body with open and close angle brackets and prior to close /HTML
with open and close angle brackets.

2.   You must act on the Unsubscribe information received from the IBD data 
feed, IBD customer service, or directly from your site, by discontinuing the
service to the subscriber, within twenty-four hours of receipt of such request.

3.   Below is the wording that must appear at the bottom of each outbound 
mailing:

/Body within open and close angle brackets
<!--
*******************************************************************************
If you've received this message in error or wish to cancel your subscription to
this service, you can either return to Netscape's In-Box Direct page and
`uncheck' the box next to <your service name> or you can <insert process for
unsubscribing directly with the content provider> . A cancellation confirmation
notice will follow.
*******************************************************************************
- -->
HTML within open and close angle brackets.

4.   You must ask the users to provide their IBD email addresses in option 1.
The correct IBD email address is not always apparent since many users have
multiple addresses, forwarding, company extensions, etc. If you attempt to use
an incorrect email address, the user's request will not be completed and user
satisfaction will suffer.

5.   Subscribers must not be required to remember a special username and a
password in order to cancel their subscription. User email address or actual
name should suffice.

6.   You must send a Goodbye/Unsubscribe Message to all IBD users who
unsubscribe from your service. This Goodbye/Unsubscribe Message must be sent to
users who unsubscribe directly from the mailing, users who unsubscribe through
In-Box Direct, and users who unsubscribe by sending a special request to IBD
feedback (handled by IBD customer service).

7.   You must send this Goodbye/Unsubscribe Message, within twenty-four hours of
receiving notification from the subscriber or Netscape.

8.   You will make reasonable efforts to work with Netscape to improve 
continually the unsubscribe process/functionality. You must promptly comply with
any new unsubscribe methodology developed by Netscape.

D. PAID SUBSCRIPTION REQUIREMENTS

1.   If you wish to offer subscribers a more in-depth paid service related to 
the same content as your free service, you may do so provided that you extend
the offer in the regular free mailing, and you make it clear that the subscriber
can continue to receive the free mailing. You must also continue to provide
content which complies with the Participation Guidelines and has been approved
by the IBD Program Manager to subscribers at no charge.




                                       7.
<PAGE>   45

2.   You cannot ask for credit card information up front or solicit your paid
service by telephone or email unless requested by subscriber.

III. BRANDING AND PROMOTIONS

You understand that the list below represents the minimum marketing requirements
with which you must comply. You will make every reasonable effort to work with
Netscape to carryout marketing efforts beyond those listed below to develop and
implement programs which promote your service as well as the In-Box Direct
program as a whole.

1.   You will display the Netscape Now and IBD logos (with a link to Netscape's
Home page and IBD page) on your home pages. If the Internet Explorer logo is
displayed in your content, the Netscape logo must be displayed with at least
equal prominence. The logos must be in place the day your content is pushed to
the IBD site.

o    The IBD logo can be obtained from:
HTTP://HOME.NETSCAPE.COM/ESCAPES/IBD/IMAGES/IBD_LOGO.GIF

home page of the country that is most relevant to you.

2.   You must display the IBD Logo (with a link to Netscape's Home page and IBD
page) on every outbound mailing to In-Box Direct subscribers. In the event that
the IBD logo is updated, you must substitute the new GIF within thirty days of

mailings containing the IBD and Netscape Now logos. The IBD Program Manager
should receive such sample either prior to or at the same time that the mailing
is sent to IBD subscribers.

o    Until the new IBD logo is developed, you must display the mailbox GIF with
the words "To subscribe to other quality publications like this, please go to
Netscape's In-Box Direct page" (with a link to In-Box Direct -
HTTP://FORM.NETSCAPE.COM/IBD/CGI-BIN/IBD-X.CGI).

o    You must not alter the GIF or text as provided by Netscape.

3.   You must place the following tag line at the bottom of each mailing to
In-Box Direct subscribers: "This mailing is best viewed through Netscape
Communicator".

4.   You must send a mailing to your current user-base (or include a feature in
a current mailing) advising your subscribers of your participation in In-Box
Direct and encouraging such subscribers to visit the In-Box Direct website. This
must be done within one month of your signing this agreement. IBD Program
Manager must receive and approve a copy of promotional mailing sent to your
current user base announcing your participation in the In-Box Direct program and
encouraging subscribers to visit the IBD web site. This copy must be provided at
least one week prior to the day of the mailing.

5.   During the duration of this Agreement, on your primary Web site you shall
provide a minimum of two days of page impressions per month for a co-branded
banner supporting your service as well as In-Box Direct as a whole. The IBD
Program Manager must be given a schedule of when the page impressions will be on
your site no later than two weeks after signing the agreement. If you do not
offer




                                       8.
<PAGE>   46

paid commercial advertising on your site, you must work with the IBD program
manager to design and implement a program of equivalent value.

o   Netscape shall provide a template for the banner.

o   You can choose to use a non co-branded Netscape In-Box Direct banner if this
is preferable.

6.   During the duration of your participation in the In-Box Direct program, if
you offer the same HTML mailing as offered to In-Box Direct subscribers directly
to users on their Web site, you must include a permanent IBD link or include the
IBD half banner in a minimum of twelve of those mailings. The IBD Program 
Manager must be given a schedule of your IBD promotional mailings to your HTML 
service subscribers not referred by IBD no later than two weeks after signing 
the agreement.

IV. FEEDBACK

1.   You should make reasonable efforts to provide Netscape with ideas for
improving the In-Box Direct program including identifying any user/provider
issues that come to your attention. Comments should be sent to
[email protected]

service. A hot button or an email address such as [email protected] should be
included on all IBD mailings. Note: Customer feedback should only be collected
if you have the resources to support it.

5.   Any trends, or issues with the overall IBD program should be forwarded to
the IBD Program Manager at [email protected]. Please include any
proposed solutions as well.

6.   You have an obligation to notify Netscape of any changes in your In-Box
Direct technical or business contacts as well as company information within five
working days of the change. All changes must be sent to
[email protected] with "New Contact/Company Information" in the
headline.

                                  ("AGREEMENT")

Upon acceptance by Netscape, this Agreement and the program guidelines
("Guidelines") for the Netscape In-Box Direct Program ("Program") shall govern
your participation in the then-current Program. You understand and agree that
Netscape reserves the right to modify terms, conditions, and policies of the
Program and Guidelines at any time.

1.   You have read and agree to provide a service to be included in the Program
which service meets the conditions stated herein and in the Guidelines. You
understand that Netscape, in its sole discretion, may determine whether to
include, or to continue including you, as a participant in the Program.

2.   Netscape may, free of charge, use your company's name, trademarks, logos,
description of service, and sample pages in connection with the Program
including after termination of the Program in conjunction with end user
unsubscribing from the program. If you reasonably object to any use of your
intellectual property, you shall notify Netscape, and Netscape will use
commercially reasonable efforts to suspend such use as soon as practicable.

3.   Information about the In-Box Direct subscribers, including but not limited
to name and contact information, provided by Netscape to you at any time
("Subscriber Information") is confidential information, as defined below.
Subscriber Information may only be used for the purposes and according to the
terms and conditions contained herein, and subject to Netscape's policy with
respect to personal data as set forth at
http://home.netscape.com/netcenter/privacy.html or such other URL as Netscape
may specify from time to time. You specifically agree not to:

a.   sell, rent, give away, share or otherwise disclose to any third party any 
Subscriber Information;

b.   send advertisements or other promotional mailings, separate and apart from

such subscriber;

explicitly and positively requested by such subscriber; and

e.   send to In-Box Direct subscribers, or target or solicit In-Box Direct
subscribers with, any mailings containing content that may be harmful to
Netscape, including but not limited to any advertisement, link, banner,
promotional piece, or endorsement of third party products and/or services
directly competitive with Netscape's software products and on-line services or
companies which produce any such products and/or services, and any message to
the effect that the content sent to subscriber may best be viewed on such third
party's product(s). The foregoing prohibitions in this Section 3.e are not
intended to restrict in any way: (i) the advertisements contained in any
material which subscribers can view by following one link in the mailings sent
by you; or (ii) the endorsements made by you of such third party's product(s)
which subscribers can view by following two or more links from the mailings sent
by you; provided, however, that such advertisements and endorsements are
included in content sent to all your subscribers; (iii) editorial reviews of
products and services; and (iv) promotions for third party 




                                      10.
<PAGE>   48

products and/or services which are not competitive with Netscape's software
products and on-line services.

4.   You acknowledge that Netscape is not currently charging you a fee to
participate in the In-Box Direct program, but that Netscape reserves the right
to do so at any time in the future.

5.   You understand that your participation in the Program begins on the date
Netscape notifies you of your acceptance into the program and continues for a
period of one (1) year unless earlier discontinued or terminated as specified
below, and is automatically renewed for a period of one (1) year unless either
party provides the other party with thirty (30) days prior written notice.
Without limiting the foregoing, you understand that either you or Netscape may
terminate your participation in the Program for convenience at any time upon
thirty (30) days prior written notice. In the event of breach, the non-breaching
party may terminate its participation upon one (1) week prior written notice to
the breaching party, unless the breaching party has remedied all breaches within

for a period of five (5) years following such termination,

b.   continue offering subscribers the ability to unsubscribe according to the

cancellation requests made by subscribers directly to you, or to Netscape and
forwarded to you by Netscape, and

Netscape Confidential Information, excluding any Subscriber Information, in your
possession or control.

guidelines, and terms and conditions of participation in the Program or to
discontinue the Program at any time by notifying you by electronic mail of such
changes at least thirty (30) days before such changes become effective. You

acceptance or rejection of such modifications and your intent to continue
participating in the program under the new format, guidelines or terms and
conditions. If Netscape receives no written response within such thirty (30)
days, you acknowledge that you will be deemed to have accepted the new format,
guidelines and/or terms and conditions of participation and must comply with the
same.

7.   You understand that you are solely responsible for any legal liability
arising out of the material sent by you to the Netscape In-Box Direct
subscribers. You represent and warrant that you hold, and will continue to hold,
the necessary rights to permit the use of the material submitted by you for
receipt by the In-Box Direct subscribers and that the permitted use, display,
performance, reproduction, distribution, publication, or transmission of the
material will not violate any criminal laws, any rights of any third parties or
any local, state, national or international laws. You agree to indemnify and
hold harmless Netscape from any and all liability, loss, damages, claims, or
causes of action, including reasonable legal fees and expenses that may be

         guidelines for utilization by both Participant and Netscape during the
         development, deployment, maintenance and support of the Service. A
         formal written Project Plan ("Project Plan") will be generated by the
         parties as a result of such planing meeting and the terms thereof shall
         be deemed part of this Addendum.

         6.1      The parties will specifically address the following 2 issues,
                  among others, at the project planning meeting:

                  (a)      Addressing Scheme. The addressing scheme for the
                           Services will be mutually agreed upon by the parties.

                  (b)      Registration Scheme. The registration scheme for the
                           Service will be determined by Netscape choosing one
                           of the following options: (i) the Netscape Universal
                           Registration scheme; (ii) the USA.NET standalone

<PAGE>   52

                           registration; or (iii) a mutually agreed upon
                           registration scheme as may be determined by the

7.       Netscape's Web Site. For purposes of this Addendum, the URL described
         in the definition of Netscape Web Site in the Agreement shall be
         replaced with the URL Netscape.com/xx

8.       Localization. Participant will be responsible for the translation and
         localization of the Service into the Local Languages in the Territory.
         Participant may engage third parties to actually perform the
         translation and localization services.

9.       Quality and Timing. For purposes of this Addendum, if the Service does
         not substantially meet expected quality or the Launch Date, Netscape
         and Participant agree to meet (via conference call or face-to-face)
         within 3 business days to resolve the issue. Both parties will make
         best efforts to rectify the situation within 30 days. If the quality or
         schedule problem is still not resolved within 30 days, Netscape
         reserves the right to contract with a third party provider of the
         Service.

10.      Best of Breed.

         10.1     For purposes of this Addendum, the following items shall be in
                  added to the Best-of-Breed Service description in Exhibit E of

                  that Participant shall only be required to provide telephone
                  support to end users if other competitive service providers

         revenues, specifically excluding taxes, from the sum of:

                                    (a)     advertising and Sponsorships net
         revenue (gross advertising revenues and/or Sponsorship fees less
         reasonable fees and commissions, including but not limited to internal
         commissions for buying and/or selling agencies, not to exceed [* *];

                                    (b)     Premium Services; and

                                    (c)     special  one-time offers net revenue

                           TRADEMARK LICENSE AGREEMENT

This Trademark License Agreement ("Agreement") is effective as of the 17th day
of April, 1998 ("Effective Date") and is entered into by and between Netscape
Communications Corporation ("Netscape"), a Delaware corporation located at 501
East Middlefield Road, Mountain View California 94043, and USA.NET ("Licensee"),
a Delaware corporation located at 1155 Kelly Johnson Boulevard, Suite 400,
Colorado Springs, CO 80920.

                                    RECITALS

A.       Netscape owns and uses the name and/or trademark NETSCAPE and the
         registered trademarks therefor as listed on Exhibit A attached hereto
         (collectively referred to as the "Marks"), in connection with its
         Internet-related software products, services and technology;

B.       Licensee produces Web sites and performs other Internet-related
         services;

C.       Licensee desires to use the trademark NETSCAPE solely in the titles set
         forth in Exhibit A in connection with Internet communication services
         in the languages and geographic territories set forth opposite such
         titles in Exhibit A; and

D.       Netscape is willing to permit such use of the Marks under the terms and
         conditions set forth in this Agreement.

NOW THEREFORE, THE PARTIES AGREE AS FOLLOWS:

1.       GRANT OF LICENSE.

         1.1      GRANT OF LICENSE. Netscape hereby grants to Licensee a
non-exclusive, nontransferable, license to use the Marks in the titles set forth
in Exhibit A solely in conjunction with Internet communication services in the
languages and geographic territories set forth in Exhibit A opposite such titles
(the "Communication Services") which shall, in part, promote Netscape's products
and services, may be jointly developed by Netscape and Licensee, and which
services shall reside on Licensee's web site located at http://www.usa.net,
deploying Licensee's servers. Licensee may only use the Marks as a collective
whole and shall not separately use any element or elements of the Marks.

         1.2      RESERVATION OF RIGHTS. Netscape hereby reserves any and all 
rights not expressly and explicitly granted in this Agreement, including
Netscape's right to authorize or license use of the Marks or any other
trademarks or names containing NETSCAPE, to any third party for use in
connection with any goods and services, including, but not limited to, Internet
communication services. Without limiting the rights reserved in the preceding
sentence, Netscape hereby reserves any and all rights to use, authorize use or
license use of the Marks or any other trademarks or names containing NETSCAPE in
any geographic territory and in any language.

                                       1

<PAGE>   2

2.       LICENSE FEE. For the rights granted to Licensee herein, Licensee shall
pay Netscape, by cashier's check or wire transfer to an account designated by
Netscape, a one-time non-refundable licensee fee of U.S. Five Million Dollars
($5,000,000) at the time of Licensee's execution of this Agreement.

3.       OWNERSHIP OF MARKS. Licensee hereby acknowledges that Netscape is the
owner of the Marks, and any trademark applications and/or registrations thereto,
agrees that it will do nothing inconsistent with such ownership and agrees that
all use of the Marks by Licensee shall inure to the benefit of Netscape.
Licensee agrees that nothing in this Agreement shall give Licensee any right,
title or interest in the Marks other than the right to use the Marks in
accordance with this Agreement. Licensee agrees not to register or attempt to
register the Marks or the Logo as a trademark, service mark, Internet domain
name, trade name, or any similar trademarks or name, with any domestic or
foreign governmental or quasi-governmental authority which would be likely to
cause confusion with the Marks. Licensee may not register or use the Marks or an
abbreviation of the Marks as part of an Internet domain name. The provisions of
this paragraph shall survive the expiration or termination of this Agreement.

4.       USE OF THE MARKS; PROTECTION OF THE MARKS.

         4.1      PROPER USE. Licensee agrees that all use of the Marks shall
only occur in connection with the Communication Services and shall be in strict
compliance with the terms of this Agreement. Licensee may use the Marks as set
forth in Section 1.1 as well as in connection with the promotion of the
Communication Services. Licensee shall use the Marks in conformance with
Netscape's trademark guidelines ("Trademark Guidelines"), set forth in Exhibit
B, which Trademark Guidelines may be revised by Netscape from time to time.
Licensee agrees not to use any other trademark or service mark in combination
with the Marks other than as described in Section 1.1. Licensee has no right to
sublicense, transfer or assign the use of the Marks or use the Marks for any
other purpose other than the purpose described herein. Unless otherwise agreed
in writing, Licensee may not use the Mark in connection with, or for the benefit
of, any third party's products or services. Licensee further agrees not to use
the Marks on or in connection with any products or services that are or could be
deemed by Netscape, in its reasonable judgment, to be obscene, pornographic,
disparaging of Netscape or its products or products, or otherwise in poor taste,
or that are themselves unlawful or whose purpose is to encourage unlawful
activities by others.

         4.2      QUALITY STANDARDS. Licensee agrees to maintain a consistent
level of quality of the Communication Services performed in connection with the
Marks substantially equal to that found in Licensee's existing Web site
services. Licensee further agrees to maintain a level of quality in connection
with its use of the Marks that is consistent with general industry standards.

         4.3      MONITORING BY NETSCAPE. Licensee acknowledges that Netscape
has no further obligations under this Agreement other than the right to
periodically monitor Licensee's use of the Marks in conjunction with the
Communication Services. Upon request by Netscape, Licensee shall provide
Netscape with representative samples of each such use prior to the time the
Marks are published on the Internet or in press materials or marketing or
advertising materials. If Netscape determines that Licensee is using the Marks
improperly, and/or in connection with Communication Services which do not meet
the standards set forth in Section 4.1 or Section 4.2, Netscape shall notify
Licensee, and Licensee shall remedy the improper use within two (2) business
days following receipt of such notice from Netscape. Use of the Marks on goods
or services other than the Communication Services or the promotion of the
Communication Services, or in a manner inconsistent with the Trademark
Guidelines, shall constitute


                                       2

<PAGE>   3



material breach of this Agreement. If such material breach has not been cured
within two (2) business days following receipt of notice from Netscape, this
Agreement shall be terminated subject to Section 7.1(a).

         4.4      LEGEND; DISCLAIMER. Licensee shall include with any online
publication or publication in print of the Marks a trademark legend indicating
that the Marks are those of Netscape, used under license, and a disclaimer that
Licensee and not Netscape has produced the Communication Services and is
responsible for the content thereof.

         4.5      COMMUNICATION SERVICES. If Netscape reasonably determines that
the Communication Services contain or present any material that constitutes an
infringement of Netscape's trademark, patents, copyrights or trade secrets,
Licensee's right to use the Marks pursuant to the grant described in Section 1.1
shall, upon written notice from Netscape of such determination, be suspended
until Licensee has revised, removed or removed links to such material to
Netscape's reasonable satisfaction. If such revision or removal of, or removal
of links to, such material to Netscape's reasonable satisfaction has not
occurred within thirty (30) days of the notice from Netscape described in the
preceding sentence, Netscape may immediately terminate the license grant
described in Section 1.1. If Netscape reasonably determines that the
Communication Services contains or presents any material that could reasonably
constitute an infringement of a third party's copyright, trademark, patents or
trade secrets, Netscape may immediately terminate this Agreement if Licensee has
not revised to Netscape's reasonable satisfaction that material or presentation
within one (1) business day of written notice from Netscape subject to Section
7.1(a).

         4.6      LICENSEE WEB SITES. If Netscape, in its sole discretion, at
any time determines that Licensee's web sites or sites operated by Licensee on
behalf of other parties contain any material or present any material in a manner
that Netscape reasonably deems inaccurate or an improper tarnishment of
Netscape, the Netscape products or the Marks, or an infringement of Netscape's
or a third party's rights, including but not limited rights under trademark,
patent, trade secret or copyright laws, or unlawful in any country or territory,
Netscape may immediately terminate this Agreement if Licensee has not revised to
Netscape's reasonable satisfaction that material or presentation within three
(3) business days of written notice from Netscape subject to Section 7.1(a).

5.       CONFIDENTIAL INFORMATION AND DISCLOSURE. Unless required by law or in
connection with the due diligence of actual or potential investors, and except
to assert its rights hereunder or for disclosures to its own employees on a
"need to know" basis, Licensee agrees not to disclose the terms of this
Agreement or matters relating thereto without the prior written consent of
Netscape, which consent shall not be unreasonably withheld.

6.       INDEMNIFICATION BY LICENSEE. Licensee agrees to indemnify Netscape and
to hold Netscape harmless from any and all liability, loss, damages, claims or
causes of action, including reasonable legal fees and expenses that may be
incurred by Netscape, arising out of Licensee's use of the marks and content on
Licensee's web sites linked to or presented in conjunction with the Marks,
except for liability, loss, damages, claims or causes of action arising out of
third party claims (i) that Licensee's use of the Marks infringe that third
party's valid and subsisting U.S. trademark registration in the Marks or (ii) in
respect of any act or omission of Netscape giving rise to liability. Netscape
shall provide Licensee with prompt written notice of any claim for which
indemnification is sought and cooperating fully with and allowing Licensee to
control the defense and settlement of such claim. Netscape may not settle any
such claim without Licensee's prior written consent, which consent shall not be
unreasonably withheld. Netscape shall have the right, at its own expense, to
participate in the defense of any such claim.

(a) any material breach by Licensee of its obligations under this Agreement
which remains uncured for thirty (30) days or more following written notice of
such breach from Netscape, (b) use of the Marks by Licensee in a manner which is
disparaging of Netscape or its products and services and which remains uncured
for two (2) days following notice from Netscape, (c) Licensee decides not to

are discontinued.

failure to perform its obligations under this Agreement due to causes beyond its
reasonable control, including but not limited to acts of God, war, riot,
embargoes, acts of civil or military authorities, fire, floods or accidents.

         8.6      WAIVER. Any waiver, either expressed or implied, by either
party of any default by the other in the observance and performance of any of
the conditions, covenants of duties set forth herein shall not constitute or be

         8.7      HEADINGS. The headings to the Sections and Subsections of this
Agreement are included merely for convenience of reference and shall not affect
the meaning of the language included therein.

         8.8      INDEPENDENT CONTRACTORS. The parties acknowledge and agree

Nothing contained in the Agreement shall be interpreted as constituting either

         8.10     EQUITABLE RELIEF. Licensee recognizes and acknowledges that a
breach by Licensee of this Agreement will cause Netscape irreparable damage
which cannot be readily remedied in monetary damages in an action at law, and
may, in addition thereto, constitute an infringement of the Marks. In the event
of any default or breach by Licensee that could result in irreparable harm to
Netscape or cause some loss or dilution of Netscape's goodwill, reputation, or
rights in the Marks, Netscape shall be entitled to immediate injunctive relief
to prevent such irreparable harm, loss, or dilution in addition to any other
remedies available.

         8.11     SEVERABILITY. Except as otherwise set forth in this Agreement,
the provisions of this Agreement are severable, and if any one or more such
provisions shall be determined to be invalid, illegal or unenforceable, in whole
or in part, the validity, legality and enforceability of any of the remaining
provisions or portions thereof shall not in any way be affected thereby and
shall nevertheless be binding between the parties hereto. Any such invalid,
illegal or unenforceable provision or portion thereof shall be changed and
interpreted so as to best accomplish the objectives of such provision or portion
thereof within the limits of applicable law.

         8.12     ATTORNEY'S FEES. In the event of any action, suit, or
proceeding brought by either party to enforce the terms of this Agreement, the
prevailing party shall be entitled to receive its costs, expert witness fees,

         8.13     LIMITATION OF LIABILITY. EXCEPT FOR A BREACH BY LICENSEE OF
ITS CONFIDENTIALITY OBLIGATIONS AS DESCRIBED IN SECTION 5, IN NO EVENT WILL
EITHER PARTY BE LIABLE TO THE OTHER FOR LOST PROFITS OR ANY FORM OF INDIRECT,
SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER FROM ANY CAUSES
OF ACTION OF ANY KIND WITH RESPECT TO THIS AGREEMENT WHETHER BASED ON CONTRACT,
TORT, OR OTHERWISE, AND WHETHER OR NOT THE OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGE. THE LIABILITY OF EITHER PARTY FOR DAMAGES OR ALLEGED
DAMAGES HEREUNDER (EXCEPT FOR DAMAGES OR ALLEGED DAMAGES ARISING UNDER SECTION
5) WHETHER IN CONTRACT OR TORT OR ANY OTHER LEGAL THEORY IS LIMITED TO AND SHALL
NOT EXCEED, IN THE AGGREGATE, AN AMOUNT EQUAL TO [     **   ].

                         USA.NET, INC. AND REGISTER.COM
                              PARTNERSHIP AGREEMENT

     Set forth below are the terms and conditions upon which USA.NET, Inc., a
Delaware corporation with offices at 1155 Kelly Johnson Blvd, Suite 400,
Colorado Springs, Colorado 80920 ("USA.NET") will provide Email Services to
Forman Interactive Corp., a New York corporation with offices at 134 Fifth
Avenue, 3rd Floor, New York NY 10011 ("REGISTER.COM") for resale to authorized
customers of Register.com's services ("CUSTOMERS"). This Agreement (the
"AGREEMENT") is effective this 1st day of March, 1999 (the "EFFECTIVE DATE").

1.   DEFINITIONS. "ACCOUNT," as used herein, shall mean a "post office" set up
on USA.NET's server for Customer's use of the Email Services, containing (i) a
Seat for use by the Postmaster (as defined below) and (ii) the number of Seats
for use by End Users, all as purchased by Customer from Register.com. "SEAT" as
used herein shall mean a mailbox created within an Account for use of the Email
Services by the Postmaster or an end user ("END-USER"), as the case may be.
"SOFTWARE" as used herein means the computer software programs developed or
licensed by USA.NET for use in connection with the provision of Email Services.
"EMAIL SERVICES" as used herein means the PostOffice.Net branded web-based email
services provided by USA.NET, including email hosting, server and network
maintenance, Account setup and technical support via email during USA.NET's
normal business hours. "DOMAIN REGISTRATION SERVICES" as used herein means
domain name registration services available through the Web site currently
located at http://www.register.com and do not include any other domain name
registration services provided by Forman Interactive Corp.

2.   APPOINTMENT; RELATIONSHIP. USA.NET hereby appoints Register.com as a
nonexclusive reseller of USA.NET's Email Services, specifically PostOffice.Net.
Register.com is an independent contractor; the relationship between USA.NET and
Register.com or Register.com's agents shall not be construed as an agency of any
kind. Neither Register.com nor its agents shall have authority to make any
agreement or incur any liability on behalf of USA.NET, except as set forth in
this Agreement.

3.   REGISTER.COM'S OBLIGATIONS.

     (a) CUSTOMER INFORMATION; TERMS AND CONDITIONS OF SERVICE. Register.com
agrees (i) to provide USA.NET with the Customer information required by Exhibit
A upon the resale of Email Services to a Customer, and to keep USA.NET informed
of any changes to such information; provided, however, that except as permitted
by the Terms and Conditions and Sections 9(b) and 17 below, USA.NET shall not
use such Customer information to contact Customers for the purpose of selling or
marketing any services including, but not limited to, Email Services to them
directly and (ii) to require each Customer to agree to be bound, and to cause
its End-Users to be bound, by USA.NET's terms and conditions attached hereto as
Exhibit B, as amended from time to time by USA.NET in its sole discretion
("TERMS AND CONDITIONS").

4.   TERMS OF USE.

     (a) ACCOUNT SETUP. Register.com may create an Account for each Customer,
containing the number of End User Seats purchased by such Customer plus one
Postmaster Seat. Each Account will be provided with a postmaster Seat which will
allow Customer to designate one person from time to time (the "POSTMASTER") who
shall have authority to (i) control the creation and deletion of End User Seats,
(ii) manage changes to the End User Seat information (such as changes to
End-User name or password) and (iii) customize the Email Services as set forth
in Section 4(b) below. Notwithstanding the foregoing, USA.NET may make such
changes to a Customer's Account and the Seats contained therein as it deems
necessary or appropriate for the functioning of the Email Services; provided
that, with respect to any material change, USA.NET shall use commercially
reasonable efforts to provide advance notice to Register.com prior to
implementing such changes.

     (b) CUSTOMIZATION. The Software permits Customer to customize certain
aspects of the Email Services. Within the parameters of the Software, which may
be modified from time to time as USA.NET deems necessary or appropriate, the
Postmaster will have control over the selection of options for those aspects. If
the 


                                       1.
<PAGE>   2

Postmaster does not customize an option, the Software shall default to USA.NET's
standard template, which template may be modified by Register.com within the
parameters set by USA.NET.

     (c) TECHNICAL SUPPORT. Except as set forth below, USA.NET shall have first
line responsibility for responding to and resolving technical support inquiries
from Customers; provided, however, that USA.NET's obligation under this Section
4(c) shall be limited to providing such technical support (i) in English, (ii)
via email and (iii) during USA.NET's normal business hours (Monday through
Friday, 8:00 a.m. until 6:00 p.m. M.T.). In the event that a Customer requires
technical support in a language other than English, Register.com acknowledges
that (i) Register.com shall have first line responsibility for providing
technical support to such Customer, in English, and (ii) USA.NET will provide
second line technical support to Register.com.

     (d) POSTMASTER TRAINING. Each Customer shall be provided with Postmaster
and End User manuals, both of which may be downloaded by the Postmaster through
the Postmaster's "Help/Feedback" section. In addition, Customers who purchase
Accounts with [   **   ] Seats or more shall be eligible for Postmaster training
provided by USA.NET over the telephone at [          **          ]; provided,
however, that USA.NET shall determine the times for the Postmaster training.

     (e) MAINTENANCE. Register.com acknowledges that USA.NET's servers go down
periodically for maintenance. USA.NET shall use commercially reasonable efforts
to schedule such maintenance during off-peak periods and no more frequently than
once per month.

     (f) STORAGE SPACE. Each Customer will be allotted a maximum of five (5)
megabytes of storage space per Seat on USA.NET's servers. Customers may purchase
additional storage space as further set forth on Exhibit C. In the event a
Customer exceeds its maximum permitted storage space, USA.NET reserves the right
to delete any and all Email messages from the Seats within such Customer's
Account who have exceeded their maximum storage space in order to bring the
storage space of such Seats back within their permitted range; provided that
USA.NET will provide the Customer with reasonable advance notice to reduce the
amount of storage space being used. If USA.NET reasonably determines in good
faith that a Customer's excess storage use is an immediate threat to USA.NET's
systems or operations, then USA.NET may immediately delete any and all Email
messages from the Seats within such Customer's Account without prior notice to
the Customer.

     (g) MODIFICATIONS. USA.NET reserves the right to modify or discontinue any
feature or functionality of the Email Services at any time; provided, however,
that USA.NET shall use commercially reasonable efforts to provide notice to
Register.com within a reasonable time prior to any modification or
discontinuance.

     (h) VIOLATION OF TERMS AND CONDITIONS. If USA.NET believes conduct by a
Customer or a Customer's End-Users violates the Terms and Conditions, or is
otherwise harmful to USA.NET or its customers, USA.NET may restrict, suspend or
terminate the provision of Email Services to such Customer. USA.NET shall use
commercially reasonable efforts to provide notice to Register.com prior to
implementing such actions.

     (i) CUSTOMER BILLING. During the term of this Agreement, Register.com shall
be solely responsible for billing and collecting Customer payments. Register.com
hereby acknowledges and affirms that Register.com's payment obligations to
USA.NET must be satisfied in full, irrespective of Register.com's billing or
collection status with any Customer.

5.   FEES; BILLING; TAXES.

     (a) FEES. For each Customer Account ordered by Register.com and setup by
USA.NET, Register.com agrees to pay both (i) monthly wholesale service fees and
(ii) as applicable, Account adjustment fees (collectively, the "Fees").
USA.NET's current fee structure is set forth on the fee schedule attached hereto
as Exhibit C (the "FEE SCHEDULE"). USA.NET reserves the right to amend the Fee
Schedule at any time, in its sole discretion, with a sixty (60) day advance
notice to Register.com. Register.com may provide each individual Customer with
[       **        ] Account containing up to [   **   ] of Seats for an initial
thirty (30) day period at [    **   ] to Register.com.


**   INDICATES CONFIDENTIAL TREATMENT REQUESTED.


                                       2.
<PAGE>   3

     (b) BILLING; PAYMENT. USA.NET shall invoice Register.com monthly for all
Fees due, less [       **        ] Accounts as provided in Section 5a.
Register.com shall pay USA.NET the amount invoiced net thirty (30) days after
receipt thereof. Any unpaid balances shall accrue interest at the prime rate,
from the due date until paid, and shall include USA.NET's reasonable cost of
collection. Each invoice will be accompanied by a report setting forth (i) the
number of Seats ordered by Register.com during the month, (ii) the number of
Seats which remained active through the end of the month, (iii) the number of
Seats cancelled during the month, (iv) Account adjustments made during the month
and (v) the type and amount of additional services ordered by Register.com on
behalf of Customers during the month.

     (c) TAXES. The Fees are exclusive of all federal, state, municipal or other
government excise, sales, use, occupational, or like taxes. Any such tax, fee,
or charge of any nature whatsoever imposed by any governmental authority on, or
measured by, the transactions between USA.NET and Register.com (exclusive of
taxes based on USA.NET's net income) shall be paid by Register.com in addition
to the Fees invoiced. All payments to USA.NET shall be made free and clear of,
and without reduction for, any withholding taxes.

6.   CO-OP MARKETING FUNDS. USA.NET will accrue and reserve [       **        ]
of each payment it receives from Register.com (the "FUNDS") which USA.NET will
use to reimburse Register.com for joint promotions of the Email Services
identified by Register.com in accordance with the license granted pursuant to
Sections 10 and 11 below and subject to the limits set forth herein. The Funds
must be used by Register.com within one (1) year of the date of accrual and the
expenditure must be approved in writing by USA.NET in accordance with USA.NET
policy.

7.   CO-MARKETING AGREEMENT. USA.NET and Register.com shall each use
commercially reasonable efforts to promote and market each other's products and
services during the term of this Agreement, which may include the promotional
efforts specified on Exhibit D attached hereto, as amended from time to time by
written agreement of the parties.

8.   MINIMUM SALES. In order to continue their rights hereunder, Register.com
shall pay USA.NET a minimum of [              **              ] in Fees per 
month (the "MINIMUM MONTHLY FEE"), which minimum obligation shall commence [
          **                ] after USA.NET implements the Application
Programming Interface ("API") for the Email Services. In the event Register.com
fails to either (i) order a sufficient number of Accounts to satisfy the Minimum
Monthly Fee requirement, or (ii) pay USA.NET the shortfall in the Minimum
Monthly Fee, USA.NET shall have the right, but not the obligation, to terminate,
or otherwise renegotiate, the co-marketing agreement specified in Section 7
above. Minimum Monthly Fees shall be paid with the Fees as set forth in Section
5(a) above.

9.   USA.NET'S OBLIGATIONS.

     (a) SERVICES. USA.NET shall, in accordance with the terms and conditions
set forth herein, use commercially reasonable efforts to provide the Email
Services to the Customers.

     (b) CUSTOMER NAMES. USA.NET shall not sell or distribute the names of the
Customers to any third parties or use the Customers' names for USA.NET's own
marketing purposes (other than the distribution of the Customers' names to
USA.NET's suppliers as necessary to provide the Email Services pursuant to this
Agreement and as set forth in the Terms and Conditions and Section 17 below),
without the prior written consent of Register.com. USA.NET shall be able to use
information relating to the aggregate number of Customers (without any reference
to Customer names) subscribing to the Email Services for its own marketing
purposes.

10.  USA.NET LICENSE GRANT. USA.NET hereby grants Register.com a revocable,
nonexclusive, nontransferable license to use USA.NET's trademarks and trade
names (the "USA.NET MARKS"), in promotional materials distributed by
Register.com during the term of this Agreement solely for the purpose of (i)
soliciting sales of the Email Services from Customers; or (ii) jointly promoting
USA.NET and Register.com. Register.com shall submit all promotional and other
materials containing USA.NET Marks to, and obtain written approval from,
USA.NET's Marketing Department, at the address specified in the preamble hereto,
prior to the distribution or use thereof. USA.NET reserves the right to revoke
the license granted hereunder as to any use of the USA.NET Marks it finds
objectionable, and Register.com shall cease using the USA.NET Marks in such
objectionable manner within 


**   INDICATES CONFIDENTIAL TREATMENT REQUESTED.

<PAGE>   4

fifteen (15) days after the date of USA.NET's written notice thereof. The
license set forth in this Section 10 shall expire immediately upon the
expiration or termination of this Agreement. Register.com's use of the license
granted herein, and any goodwill arising therefrom, shall inure to the sole
benefit of USA.NET. Register.com shall not promote the Email Services under any
trademark or trade name other than the USA.NET Marks, except as expressly
permitted by USA.NET. USA.NET will monitor the quality of the services for which
Register.com will be using the USA.NET Marks to ensure that they conform to the
standards of quality of USA.NET's other services. Register.com agrees not to
adopt or use any other trademarks, words, symbols, letters, designs or marks in
combination with the USA.NET Marks in a manner that would create combination
marks or that would be confusingly similar to the USA.NET Marks. Register.com
shall not seek or obtain any trademark or trade name registration embodying the
USA.NET Marks, nor register or cause to be registered any USA.NET Marks in
Register.com's own name. In addition, Register.com will not seek to challenge
the validity of the USA.NET Marks.

11.  REGISTER.COM LICENSE GRANT. Register.com hereby grants USA.NET a revocable,
nonexclusive, nontransferable license to use Register.com's trademarks and trade
names (the "REGISTER.COM MARKS"), during the term of this Agreement solely for
the purpose of promoting Register.com as set forth herein in Section 7.
Register.com reserves the right to revoke the license granted hereunder as to
any use of the Register.com Marks it finds objectionable, and USA.NET shall
cease using the Register.com Marks in such objectionable manner within fifteen
(15) days after the date of Register.com's written notice thereof. The license
set forth in this Section 11 shall expire immediately upon the expiration or
termination of this Agreement. USA.NET's use of the license granted herein, and
any goodwill arising therefrom, shall inure to the sole benefit of Register.com.
Register.com will monitor the quality of the services for which USA.NET will be
using the Register.com Marks to ensure that they conform to the standards of
quality of Register.com's other services. USA.NET agrees not to adopt or use any
other trademarks, words, symbols, letters, designs or marks in combination with
the Register.com Marks in a manner that would create combination marks or that
would be confusingly similar to the Register.com Marks. USA.NET shall not seek
or obtain any trademark or trade name registration embodying the Register.com
Marks, nor register or cause to be registered any Register.com Marks in
USA.NET's own name. In addition, USA.NET will not seek to challenge the validity
of the Register.com Marks.

12.  TERM. This Agreement shall have a term of one (1) year commencing on the
Effective Date, unless terminated earlier pursuant to Section 13 or Section 14
below (the "INITIAL TERM") and shall be automatically renewed for successive one
year terms (each a "SUBSEQUENT TERM").

13.  TERMINATION FOR CONVENIENCE. During the Initial Term, either party may
terminate this Agreement for any reason upon at least six (6) months written
notice. During any Subsequent Term, either party may terminate this Agreement
for any reason upon at least sixty (60) days written notice.

14.  TERMINATION FOR CAUSE. Either party may terminate this Agreement upon
thirty (30) days written notice to the other party upon (i) a material breach of
the terms of this Agreement, including, but not limited to, any default in
payment obligations which have not been cured or addressed within thirty (30)
days of notice of breach or (ii) the liquidation of the other party's assets.

15.  TERMINATION BY REGISTER.COM. Register.com may terminate this Agreement, at
their sole discretion, on thirty (30) days written notice to USA.NET, if USA.NET
sells advertisements in any particular month on any USA.NET branded Email
Services site, including NET@DDRESS and PostOffice.Net, to [    **   ] which
exceeds the prior monthly average of advertising sales to [   **    ]. USA.NET
agrees to notify Register.com in writing prior to such an increase taking
effect. Notwithstanding the foregoing, the termination obligations set forth
herein shall not include any privately branded USA.NET Email Services, including
but not limited to AmExMail and Netscape WebMail. USA.NET acknowledges that
[   **    ] is the only current advertiser that [                     **     
              ] on any USA.NET branded Email Services site, including 
NET@DDRESS and PostOffice.Net.

16.  EFFECT OF TERMINATION.

     (a) Upon termination of this Agreement, whether for convenience or for
cause, each party shall immediately cease all efforts to promote and market the

**   INDICATES CONFIDENTIAL TREATMENT REQUESTED.


                                       4.
<PAGE>   5

shall not be obligated to continue to provide the Email Services to the
Customers unless USA.NET receives an assignment of the Customers as provided in
Section 17.

     (b) Immediately upon the expiration or termination of this Agreement, (i)
Register.com shall cease all use of the USA.NET Marks, (ii) USA.NET shall cease
all use of the Register.com Marks, and (iii) Register.com shall return all
USA.NET property in Register.com's possession or control.

     (c) Neither party shall incur any liability whatsoever for any damage, loss
or expenses of any kind suffered or incurred by the other because of the act of
termination or the expiration of this Agreement, in either case in a manner
which complies with the terms of this Agreement. Without limiting the foregoing,
neither party shall be entitled to any damages on account of prospective profits
or anticipated sales. Register.com waives the benefit of any law or regulation
providing compensation to Register.com arising from the termination of or
failure to renew this Agreement and Register.com represents and warrants that
such waiver is irrevocable and enforceable by USA.NET. However, all payments
normally due to one party by the other party shall be paid in full immediately
upon termination or expiration of this Agreement.

17.  ASSIGNMENT OF CUSTOMERS. In the event that this Agreement is terminated for
any reason whatsoever, other than termination by USA.NET for cause pursuant to
Section 14 above, Register.com may require that USA.NET pay to effect a transfer
of all rights to contact the Customers as follows: (i) USA.NET shall pay
Register.com an amount equal to [     **    ] times the Fees Register.com
received from the Customers in the last full month immediately preceding the
effective date of termination and (ii) Register.com shall be automatically
deemed to have immediately transferred and assigned to USA.NET all rights to
contact the Customers for the purpose of offering, marketing and selling the
Email Services to the Customers directly. In the event this Agreement is
terminated by USA.NET for cause pursuant to Section 14 above, Register.com, at
no charge to USA.NET, shall be automatically deemed to have immediately
transferred and assigned to USA.NET the right to contact the Customers for the
purpose of offering, marketing and selling the Email Services to the Customers
directly. Upon any such transfer, USA.NET will assume full responsibility for
billing and collecting payments from any Customers who accept such offer and may
immediately cancel Email Services for all Customers who decline such offer. In
the event that USA.NET acquires an assignment of the Customers as provided in
this Section 17, then Register.com agrees that it will not, directly or
indirectly, for a period of [   **   ) years after the effective date of such
assignment, solicit, market or promote to, sell or distribute any services which
are competitive with the Email Services to any Customers; provided however, that
Register.com may advertise and promote any competitive services to the Customers
in connection with general advertisements and promotions so long as the
advertisements and promotions are not directed at the Customers and so long as
Register.com does not use the Customer names in any way for the sale or
marketing of any services which are competitive with the Email Services.

18.  WARRANTY DISCLAIMERS AND LIMITATION OF LIABILITY.

                          CUSTOMER TERMS AND CONDITIONS



1.   SPAMMING, REDISTRIBUTION PROHIBITED. Spamming and bulk mail, as determined
by USA.NET in its sole discretion, is strictly prohibited. This includes, but is
not limited to, the transmission of any message or bulk mail that can be
interpreted as "junk" mail, mail generated via mass-mailer distribution list, or
mail which the recipient would not reasonably expect to receive. In addition,
reselling, redistribution, or repackaging of any email services provided by
USA.NET is strictly prohibited, except as otherwise expressly permitted by
USA.NET in writing.

2.   USER CONTENT. USA.NET acts as a passive conduit for the distribution of
data and the User is solely responsible for content. User represents and
warrants that the content provided to USA.NET (or its servers) (a) does not
infringe on any third party's copyright, patent, trademark, trade secret or
other intellectual property or proprietary rights or rights of publicity or
privacy; (b) does not violate any law, statute, ordinance, or regulation
(including without limitation the laws and regulations governing export
control); (c) is not defamatory, trade libelous, pornographic, obscene,
unlawfully threatening or unlawfully harassing; (d) does not violate any laws
regarding unfair competition, anti-discrimination or false advertising, and (e)
does not contain viruses, trojan horses, worms, time bombs, cancelbots or other
similarly harmful or deleterious programming routines that are intended to
damage, detrimentally interfere with, surreptitiously intercept or expropriate
any system, data or personal information. The term "User" as used herein shall
include the customer which purchased the account and such customer's end-users.

3.   SERVICE LEVELS. USA.NET will provide the email service at the level
purchased at account initiation or as a result of subsequent email service
upgrades. Email service levels are determined by the number of seats, amount of
storage and additional services purchased. Each email service level has
pre-determined seat, storage, and additional service thresholds.

4.   TERM AND TERMINATION. Email services provided by USA.NET shall commence on
the day of account initiation, and shall continue until cancelled by Customer or
USA.NET or until User is deemed non-compliant with the terms or conditions set
forth herein, as determined by USA.NET in its sole discretion.

5.   DISCLAIMER OF WARRANTIES. THE EMAIL SERVICES ARE PROVIDED ON AN "AS IS"
AND "AS AVAILABLE" BASIS. USA.NET EXPRESSLY DISCLAIMS ALL WARRANTIES OF ANY
KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND
NON-INFRINGEMENT. USA.NET MAKES NO WARRANTY THAT THE EMAIL SERVICES WILL BE
UNINTERRUPTED, TIMELY, SECURE, OR ERROR FREE; NOR DOES USA.NET MAKE ANY WARRANTY
AS TO THE RESULTS THAT MAY BE OBTAINED THROUGH THE EMAIL SERVICES OR THAT ANY
DEFECTS IN THE SOFTWARE WILL BE CORRECTED. USA.NET WILL NOT BE RESPONSIBLE FOR
ANY DAMAGE TO ANY COMPUTER SYSTEM OR LOSS OF DATA THAT RESULTS FROM ANY MATERIAL
AND/OR DATA DOWNLOADED OR OTHERWISE OBTAINED THROUGH THE USE OF THE EMAIL
SERVICE OR THE SYSTEM, NOTWITHSTANDING THE PURCHASE OF VIRUS PROTECTION FROM
USA.NET. USA.NET MAKES NO WARRANTY REGARDING ANY GOODS OR SERVICES PURCHASED OR
OBTAINED THROUGH THE EMAIL SERVICES OR ANY TRANSACTIONS ENTERED INTO THROUGH THE
EMAIL SERVICES. NO ADVICE OR INFORMATION, WHETHER ORAL OR WRITTEN, OBTAINED FROM

MADE HEREIN.


                                       2.
<PAGE>   12

6.   LIMITATION OF LIABILITY. USA.NET SHALL NOT BE LIABLE FOR ANY INDIRECT,
INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES OR FOR INTERRUPTED COMMUNICATIONS,
LOST DATA OR LOST PROFITS ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT,
EVEN IF USA.NET HAS BEEN ADVISED OF THE POSSIBILITY OF DAMAGES.

7.   GOVERNING LAW. Any dispute arising out of the provision of email services
by USA.NET will be governed by and construed in accordance with the laws of the
State of Colorado without giving effect to principles of conflict of laws. If
any provision of these terms and conditions is held to be invalid or
unenforceable, such provision shall be struck and the remaining provisions shall
be enforced. USA.NET's failure to act with respect to a breach by User or others
does not waive its right to act with respect to subsequent or similar breaches.

8.   CONTENT REMOVAL/RETENTION. Upon the termination of User's account, USA.NET
may remove some or all of the User content from its servers or may elect to
retain such content, at USA.NET's sole discretion.

9.   PRIVACY. Although privacy issues are very important to USA.NET, given the
current regulatory and technical environment User should not have an expectation
of privacy in its account. By way of example (without limiting the foregoing),
USA.NET may be forced to disclose email to the government or third parties under
certain circumstances, or third parties may unlawfully intercept User's private
communications. USA.NET cannot ensure that all private email or information
associated with User's account will remain private.

10.   ACCESS TO CONTENT OF OTHERS. Through User's account, USA.NET provides User
with unfiltered access to other people's content. USA.NET cannot, nor does it
try to, control the content that User will receive. By its very nature, other
people's content may be offensive, harmful or inaccurate, and in some cases
content will be mislabeled or deceptively labeled. USA.NET expects that User
will use caution--and common sense--when using its account. Furthermore, User
shall comply with all applicable laws regarding User's access to its account.

11.   AMENDMENT. User acknowledges and agrees that (i) USA.NET may amend these
Terms and Conditions at any time in its sole discretion (ii) the Terms and
Conditions, as amended from time to time may be accessed and viewed by User at
any time by clicking on the "Terms and Conditions" link located at the bottom of
each page of User's personalized postoffice.net site, (iii) providing access to
the Terms and Conditions, as amended from time to time through such links shall
be adequate notice to User of any such amendment and (iv) User will be deemed to
have accepted the amended Terms and Conditions if User continues to use its
account after such Terms and Conditions have been made available for viewing
through such links. Except as set forth in this Section 11, the Terms and
Conditions may not be amended except in a writing signed by both parties.

     documents or financing statements relating to such properties. All of
     Borrower's properties are titled in Borrower's legal name, and Borrower has
     not used, or filed a financing statement under, any other name for at least
     the last five (5) years.

     HAZARDOUS SUBSTANCES. The terms "hazardous waste," "hazardous substance,"
     "disposal," "release," and "threatened release," as used in this Agreement,
     shall have the same meanings as set forth in the "CERCLA," "SARA," the
     Hazardous Materials Transportation Act, 49 U.S.C. Section 1801, et seq.,
     the Resource Conservation and Recovery Act, 42 U.S.C. Section 6901, et
     seq., or other applicable state or Federal laws, rules, or regulations
     adopted pursuant to any of the foregoing. Except as disclosed to and
     acknowledged by Lender in writing, Borrower represents and warrants that:
     (a) During the period of Borrower's ownership of the properties, there has
     been no use, generation, manufacture, storage, treatment, disposal, release
     or threatened release of any hazardous waste or substance by any person on,
     under, about or from any of the properties. (b) Borrower has no knowledge
     of, or reason to believe that there has been (i) any use, generation,
     manufacture, storage, treatment, disposal, release, or threatened release
     of any hazardous waste or substance on, under, about or from the properties
     by any prior owners or occupants of any of the properties, or (ii) any
     actual or threatened litigation or claims of any kind by any person
     relating to such matters. (c) Neither Borrower nor any tenant, contractor,
     agent or other authorized user of any of the properties shall use,
     generate, manufacture, store, treat, dispose of, or release any hazardous
     waste or substance on, under, about or from any of the properties; and any
     such activity shall be conducted in compliance with all applicable federal,
     state, and local laws, regulations, and ordinances, including without
     limitation those laws, regulations and ordinances described above. Borrower
     authorizes Lender and its agents to enter upon the properties to make such
     inspections and tests as Lender may deem appropriate to determine
     compliance of the properties with this section of the Agreement. Any
     inspections or tests made by Lender shall be at Borrower's expense and for
     Lender's purposes only and shall not be construed to create any
     responsibility or liability on the part of Lender to Borrower or to any
     other person. The representations and warranties contained herein are based
     on Borrower's due diligence in investigating the properties for hazardous
     waste and hazardous substances. Borrower hereby (a) releases and waives any
     future claims against Lender for indemnity or contribution in the event
     Borrower becomes liable for cleanup or other costs under any such laws, and
     (b) agrees to indemnify and hold harmless Lender against any and all
     claims, losses, liabilities, damages, penalties, and expenses which Lender
     may directly or indirectly sustain or suffer resulting from a breach of
     this section of the Agreement or as a consequence of any use, generation,
     manufacture, storage, disposal, release or threatened release occurring
     prior to Borrower's ownership or interest in the properties, whether or not
     the same was or should have been known to Borrower. The provisions of this
     section of the Agreement, including the obligation to indemnify, shall
     survive the payment of the Indebtedness and the termination or expiration
     of this Agreement and shall not be affected by Lender's acquisition of any
     interest in any of the properties, whether by foreclosure or otherwise.

     LITIGATION AND CLAIMS. No litigation, claim, investigation, administrative
     proceeding or similar action (including those for unpaid taxes) against
     Borrower is pending or threatened, and no other event has occurred which
     may materially adversely affect Borrower's financial condition or
     properties, other than litigation, claims, or other events, if any, that
     have been disclosed to and acknowledged by Lender in writing.

     TAXES. To the best of Borrower's knowledge, all tax returns and reports of
     Borrower that are or were required to be filed, have been filed, and all
     taxes, assessments and other governmental charges have been paid in full,
     except those presently being or to be contested by Borrower in good faith
     in the ordinary course of business and for which adequate reserves have
     been provided.

     LIEN PRIORITY. Unless otherwise previously disclosed to Lender in writing,
     Borrower has not entered into or granted any Security Agreements, or
     permitted the filing or attachment of any Security Interests on or
     affecting any of the Collateral directly or indirectly securing repayment
     of Borrower's Loan and Note, that would be prior or that may in any way be
     superior to Lender's Security Interests and rights in and to such
     Collateral.

     BINDING EFFECT. This Agreement, the Note, all Security Agreements directly
     or indirectly securing repayment of Borrower's Loan and Note and all of the
     Related Documents are binding upon Borrower as well as upon Borrower's
     successors, representatives and assigns, and are legally enforceable in
     accordance with their respective terms.

     business or commercial related purposes.

     have any liability complies in all material respects with all applicable

     initiated steps to do so, (iii) no steps have been taken to terminate any

     of business, is located at 102 South Tejon, Suite 220, Colorado Springs, CO

     this Agreement or any transaction contemplated hereby is, and all
     information hereafter furnished by or on behalf of Borrower to Lender will

     such information is dated or certified; and none of such information is or

     such information not misleading.

     that Lender, without independent investigation, is relying upon the above
     representations and warranties in making the above referenced Loan to

     effect until such time as Borrower's Indebtedness shall be paid in full, or
     until this Agreement shall be terminated in the manner provided above,
     whichever is the last to occur.

     generally accepted accounting principles, applied on a consistent basis,

     ADDITIONAL INFORMATION. Furnish such additional information and statements,
     lists of assets and liabilities, agings of receivables and payables,
     inventory schedules, budgets, forecasts, tax returns, and other reports
     with respect to Borrower's financial condition and business operations as
     Lender may request from time to time.

     INSURANCE. Maintain fire and other risk insurance, public liability
     insurance, and such other insurance as Lender may require with respect to
     Borrower's properties and operations, in form, amounts, coverages and with
     insurance companies reasonably acceptable to Lender. Borrower, upon request
     of Lender, will deliver to Lender from time to time the policies or
     certificates of insurance in form satisfactory to Lender, including
     stipulations that coverages will not be cancelled or diminished without at
     least ten (10) days' prior written notice to Lender. Each insurance policy
     also shall include an endorsement providing that coverage in favor of
     Lender will not be impaired in any way by any act, omission or default of
     Borrower or any other person. In connection with all policies covering
     assets in which Lender holds or is offered a security interest for the
     Loans, Borrower will provide Lender with such loss payable or other
     endorsements as Lender may require.

     INSURANCE REPORTS. Furnish to Lender, upon request of Lender, reports on
     each existing insurance policy showing such information as Lender may
     reasonably request, including without limitation the following: (a) the
     name of the insurer; (b) the risks insured; (c) the amount of the policy;
     (d) the properties insured; (e) the then current property values on the
     basis of which insurance has been obtained, and the manner of determining
     those values; and (f) the expiration date of the policy. In addition, upon
     request of Lender (however not more often than annually), Borrower will
     have an independent appraiser satisfactory to Lender determine, as
     applicable, the actual cash value or replacement cost of any Collateral.
     The cost of such appraisal shall be paid by Borrower.

     GUARANTIES. Prior to disbursement of any Loan proceeds, furnish executed
     guaranties of the Loans in favor of Lender, executed by the guarantor named
     below, on Lender's forms, and in the amount and under the conditions
     spelled out in those guaranties.

     OTHER AGREEMENTS. Comply with all terms and conditions of all other
     agreements, whether now or hereafter existing, between Borrower and any
     other party and notify Lender immediately in writing of any default in

     taxes, governmental charges, levies and liens, of every kind and nature,
     imposed upon Borrower or its properties, income, or profits, prior to the
     date on which penalties would attach, and all lawful claims that, if
     unpaid, might become a lien or charge upon any of Borrower's properties,
     income, or profits. Provided however, Borrower will not be required to pay
     and discharge any such assessment, tax, charge, levy, lien or claim so long
     as (a) the legality of the same shall be contested in good faith by
     appropriate proceedings, and (b) Borrower shall have established on its
     books adequate reserves with respect to such contested assessment, tax,
     charge, levy, lien, or claim in accordance with generally accepted
     accounting practices. Borrower, upon demand of Lender, will furnish to
     Lender evidence of payment of the assessments, taxes, charges, levies,
     liens and claims and will authorize the appropriate governmental official
     to deliver to Lender at any time a written statement of any assessments,
     taxes, charges, levies, liens and claims against Borrower's properties,
     income, or profits.

     set forth in this Agreement and in the Related Documents in a timely
     manner, and promptly notify Lender if Borrower learns of the occurrence of
     any event which constitutes an Event of Default under this Agreement or
     under any of the Related Documents.

     the same qualifications and experience as the present executive and
     management personnel; provide written notice to Lender of any change in
     executive and management personnel; conduct its business affairs in a
     reasonable and prudent manner and in compliance with all applicable
     federal, state and municipal laws, ordinances, rules and regulations
     respecting its properties, charters, businesses and operations, including
     without limitation, compliance with the Americans With Disabilities Act and
     with all minimum funding standards and other requirements of ERISA and
     other laws applicable to Borrower's employee benefit plans.

     INSPECTION. Permit employees or agents of Lender at any reasonable time to
     inspect any and all Collateral for the Loan or Loans and Borrower's other
     properties and to examine or audit Borrower's books, accounts, and records
     and to make copies and memoranda of Borrower's books, accounts, and
     records. If Borrower now or at any time hereafter maintains any records
     (including without limitation computer generated records and computer
     software programs for the generation of such records) in the possession of
     a third party, Borrower, upon request of Lender, shall notify such party to
     permit Lender free access to such records at all reasonable times and to
     provide Lender with copies of any records it may request, all at Borrower's
     expense.

     COMPLIANCE CERTIFICATE. Unless waived in writing by Lender, provide Lender
     at least annually and at the time of each disbursement of Loan proceeds
     with a certificate executed by Borrower's chief financial officer, or other
     officer or person acceptable to Lender, certifying that the representations
     and warranties set forth in this Agreement are true and correct as of the

     intentional or unintentional action or omission on its part of on the part
     of any third party, on property owned and/or occupied by Borrower, any
     environmental activity where damage may result to the environment, unless

     governmental authorities; shall furnish to Lender promptly and in any event
     within thirty (30) days after receipt thereof a copy of any notice,
     summons, lien, citation, directive, letter or other communication from any
     governmental agency or instrumentality concerning any intentional or
     unintentional action or omission on Borrower's part in connection with any
     environmental activity whether or not there is damage to the environment
     and/or other natural resources.

     ADDITIONAL ASSURANCES. Make, execute and deliver to Lender such promissory
     notes, mortgages, deeds of trust, security agreements, financing
     statements, instruments, documents and other agreements as Lender or its
     attorneys may reasonably request to evidence and secure the Loans and to
     perfect all Security Interests.

NEGATIVE COVENANTS. Borrower covenants and agrees with Lender that while this
Agreement is in effect, Borrower shall not, without the prior written consent of
Lender:

     INDEBTEDNESS AND LIENS. (a) Except for trade debt incurred in the normal
     course of business and indebtedness to Lender contemplated by this
     Agreement, create, incur or assume indebtedness for borrowed money,
     including capital leases, (b) except as allowed as a Permitted Lien, sell,
     transfer, mortgage, assign, pledge, lease, grant a security interest in, or
     encumber any of Borrower's assets, or (c) sell with recourse any of

     (b) cease operations, liquidate, merge, transfer, acquire or consolidate
     with any other entity, change ownership, change its name, dissolve or
     transfer or sell Collateral out of the ordinary course of business, (c) pay
     any dividends on Borrower's stock (other than dividends payable in its
     stock), provided, however that notwithstanding the foregoing, but only so
     long as no Event of Default has occurred and is continuing or would result
     from the payment of dividends, if Borrower is a "Subchapter S Corporation"
     (as defined in the Internal Revenue Code of 1986, as amended), Borrower may
     pay cash dividends on its stock to its shareholders from time to time in
     amounts necessary to enable the shareholders to pay income taxes and make
     estimated income tax payments to satisfy their liabilities under federal
     and state law which arise solely from their status as Shareholders of a
     Subchapter S Corporation because of their ownership of shares of stock of
     Borrower, or (d) purchase or retire any of Borrower's outstanding shares or

     enterprise or entity, or (c) incur any obligation as surety or guarantor
     other than in the ordinary course of business.

CESSATION OF ADVANCES. If Lender has made any commitment to make any Loan to
Borrower, whether under this Agreement or under any other agreement, Lender
shall have no obligation to make Loan Advances or to disburse Loan proceeds if:
(a) Borrower or any Guarantor is in default under the terms of this Agreement or
any of the Related Documents or any other agreement that Borrower or any
Guarantor has with Lender; (b) Borrower or any Guarantor becomes insolvent,
files a petition in bankruptcy or similar proceedings, or is adjudged a
bankrupt; (c) there occurs a material adverse change in Borrower's financial
condition, in the financial condition of any Guarantor, or in the value of any
Collateral securing any Loan; (d) any Guarantor seeks, claims or otherwise
attempts to limit, modify or revoke such Guarantor's guaranty of the Loan or any
other loan with Lender; or (e) Lender in good faith deems itself insecure, even
though no Event of Default shall have occurred.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's accounts
with Lender (whether checking, savings, or some other account), including
without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA and Keogh accounts,
and all trust accounts for which the grant of a security interest would be
prohibited by law. Borrower authorizes Lender, to the extent permitted by
applicable law, to charge or setoff all sums owing on the Indebtedness against
any and all such accounts.

EVENTS OF DEFAULT. Each of the following shall constitute an Event of Default
under this Agreement:

     DEFAULT ON INDEBTEDNESS. Failure of Borrower to make any payment when due
     on the Loans.

     OTHER DEFAULTS. Failure of Borrower or any Grantor to comply with or to
     perform when due any other term, obligation, covenant or condition
     contained in this Agreement or in any of the Related Documents, or failure
     of Borrower to comply with or to perform any other term, obligation,
     covenant or condition contained in any other agreement between Lender and
     Borrower.

     DEFAULT IN FAVOR OF THIRD PARTIES. Should Borrower or any Grantor default
     under any loan, extension of credit, security agreement, purchase or sales
     agreement, or any other agreement, in favor of any other creditor or person
     that may materially affect any of Borrower's property or Borrower's or any
     Grantor's ability to repay the Loans or perform their respective
     obligations under this Agreement or any of the Related Documents.

     FALSE STATEMENTS. Any warranty, representation or statement made or
     furnished to Lender by or on behalf of Borrower or any Grantor under this
     Agreement or the Related Documents is false or misleading in any material
     respect at the time made or furnished, or becomes false or misleading at
     any time thereafter.

     DEFECTIVE COLLATERALIZATION. This Agreement or any of the Related Documents
     ceases to be in full force and effect (including failure of any Security
     Agreement to create a valid and perfected Security Interest) at any time
     and for any reason.

     INSOLVENCY. The dissolution or termination of Borrower's existence as a
     going business, the insolvency of Borrower, the appointment of a receiver
     for any part of Borrower's property, and assignment for the benefit of
     creditors, any type of creditor workout, or the commencement of any
     proceeding under any bankruptcy or insolvency laws by or against Borrower.

     CREDITOR OR FORFEITURE PROCEEDINGS. Commencement of foreclosure or
     forfeiture proceedings, whether by judicial proceeding, self-help,
     repossession or any other method, by any creditor of Borrower, any creditor
     of any Grantor against any collateral securing the Indebtedness, or by any
     governmental agency. This includes a garnishment, attachment, or levy on or
     of any of Borrower's deposit accounts with Lender.

     EVENTS AFFECTING GUARANTOR. Any of the preceding events occurs with respect
     to any Guarantor of any of the Indebtedness or any Guarantor dies or
     becomes incompetent, or revokes or disputes the validity of, or liability
     under, any Guaranty of the Indebtedness.

     CHANGE IN OWNERSHIP. Any change in ownership of twenty-five percent (25%)
     or more of the common stock of Borrower.

LOAN NO 1014868                 (Continued)            
================================================================================

     ADVERSE CHANGE. A material adverse change occurs in Borrower's financial
     condition, or Lender believes the prospect of payment or performance of the
     Indebtedness is impaired.

     INSECURITY. Lender, in good faith, deems itself insecure.

otherwise provided in this Agreement or the Related Documents, all commitments
and obligations of Lender under this Agreement or the Related Documents or any
other agreement immediately will terminate and, at Lender's option, all
Indebtedness immediately will become due and payable, all without notice of any
kind to Borrower, except that in the case of an Event of Default of the type
described in the "Insolvency" subsection above, such acceleration shall be
automatic and not optional. In addition, Lender shall have all the rights and
remedies provided in the Related Documents or available at law, in equity, or
otherwise. Except as may be prohibited by applicable law, all of Lender's rights
and remedies shall be cumulative and may be exercised singularly or
concurrently. Election by Lender to pursue any remedy shall not exclude pursuit
of any other remedy, and an election to make expenditures or to take action to
perform an obligation of Borrower or of any Grantor shall not affect Lender's
right to declare a default and to exercise its rights and remedies.


MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of
this Agreement:

     AMENDMENTS. This Agreement, together with any Related Documents,
     constitutes the entire understanding and agreement of the parties as to the
     matters set forth in this Agreement. No alteration of or amendment to this
     Agreement shall be effective unless given in writing and signed by the
     party or parties sought to be charged or bound by the alteration or
     amendment.

     APPLICABLE LAW. THIS AGREEMENT HAS BEEN DELIVERED TO LENDER AND ACCEPTED BY
     LENDER IN THE STATE OF COLORADO. IF THERE IS A LAWSUIT, BORROWER AGREES
     UPON LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE COURTS OF EL
     PASO COUNTY, THE STATE OF COLORADO. LENDER AND BORROWER HEREBY WAIVE THE
     RIGHT TO ANY JURY TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT
     BY EITHER LENDER OR BORROWER AGAINST THE OTHER. (INITIAL HERE __________)
     THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
     LAWS OF THE STATE OF COLORADO.

     CAPTION HEADINGS. Caption headings in this Agreement are for convenience
     purposes only and are not to be used to interpret or define the provisions
     of this Agreement.

     CONSENT TO LOAN PARTICIPATION. Borrower agrees and consents to Lender's
     sale or transfer, whether now or later, of one or more participation
     interests in the Loans to one or more purchasers, whether related or
     unrelated to Lender. Lender may provide, without any limitation whatsoever,
     to any one or more purchasers, or potential purchasers, any information or
     knowledge Lender may have about Borrower or about any other matter relating
     to the Loan, and Borrower hereby waives any rights to privacy it may have
     with respect to such matters. Borrower additionally waives any and all
     notices of sale of participation interests, as well as all notices of any
     repurchase of such participation interests. Borrower also agrees that the
     purchasers of any such participation interests will be considered as the
     absolute owners of such interests in the Loans and will have all the rights
     granted under the participation agreement or agreements governing the sale
     of such participation interests. Borrower further waives all rights of
     offset or counterclaim that it may have now or later against Lender or
     against any purchaser of such a participation interest and unconditionally
     agrees that either Lender or such purchaser may enforce Borrower's
     obligation under the Loans irrespective of the failure or insolvency of any
     holder of any interest in the Loans. Borrower further agrees that the
     purchaser of any such participation interests may enforce its interests
     irrespective of any personal claims or defenses that Borrower may have
     against Lender.

     COSTS AND EXPENSES. Borrower agrees to pay upon demand all of Lender's
     expenses, including without limitation attorneys' fees, incurred in
     connection with the preparation, execution, enforcement, modification and
     collection of this Agreement or in connection with the Loans made pursuant
     to this Agreement. Lender may pay someone else to help collect the Loans
     and to enforce this Agreement, and Borrower will pay that amount. This
     includes, subject to any limits under applicable law, Lender's attorneys'
     fees and Lender's legal expenses, whether or not there is a lawsuit,
     including attorneys' fees for bankruptcy proceedings (including efforts to
     modify or vacate any automatic stay or injunction), appeals, and any
     anticipated post-judgment collection services. Borrower also will pay any
     court costs, in addition to all other sums provided by law.

     NOTICES. All notices required to be given under this Agreement shall be
     given in writing, may be sent by telefacsimile (unless otherwise required
     by law), and shall be effective when actually delivered or when deposited
     with a nationally recognized overnight courier or deposited in the United
     States mail, first class, postage prepaid, addressed to the party to whom
     the notice is to be given at the address shown above. Any party may change
     its address for notices under this Agreement by giving formal written
     notice to the other parties, specifying that the purpose of the notice is
     to change the party's address. To the extent permitted by applicable law,
     if there is more than one Borrower, notice to any Borrower will constitute
     notice to all Borrowers. For notice purposes, Borrower will keep Lender
     informed at all times of Borrower's current address(es).

     SEVERABILITY. If a court of competent jurisdiction finds any provision of
     this Agreement to be invalid or unenforceable as to any person or
     circumstance, such finding shall not render that provision invalid or
     unenforceable as to any other persons or circumstances. If feasible, any
     such offending provision shall be deemed to be modified to be within the
     limits of enforceability or validity; however, if the offending provision
     cannot be so modified, it shall be stricken and all other provisions of
     this Agreement in all other respects shall remain valid and enforceable.

     SUCCESSORS AND ASSIGNS. All covenants and agreements contained by or on
     behalf of Borrower shall bind its successors and assigns and shall inure to
     the benefit of Lender, its successors and assigns. Borrower shall not,
     however, have the right to assign its rights under this Agreement or any
     interest therein, without the prior written consent of Lender.

     SURVIVAL. All warranties, representations, and covenants made by Borrower
     in this Agreement or in any certificate or other instrument delivered by
     Borrower to Lender under this Agreement shall be considered to have been
     relied upon by Lender and will survive the making of the Loan and delivery
     to Lender of the Related Documents, regardless of any investigation made by
     Lender or on Lender's behalf.

     TIME IS OF THE ESSENCE. Time is of the essence in the performance of this
     Agreement.

     WAIVER. Lender shall not be deemed to have waived any rights under this
     Agreement unless such waiver is given in writing and signed by Lender. No
     delay or omission on the part of Lender in exercising any right shall
     operate as a waiver of such right or any other right. A waiver by Lender of
     a provision of this Agreement shall not prejudice or constitute a waiver of
     Lender's right otherwise to demand strict compliance with that provision or
     any other provision of this Agreement. No prior waiver by Lender, nor any
     course of dealing between Lender and Borrower, or between Lender and any
     Grantor, shall constitute a waiver of any of Lender's rights or of any
     obligations of Borrower or of any Grantor as to any future transactions.
     Whenever the consent of Lender is required under this Agreement, the
     granting of such consent by Lender in any instance shall not constitute
     continuing consent in

              PAYMENTS WILL BE MADE EXACTLY AS SCHEDULED AND THAT THE INDEX DOES
              NOT CHANGE; THE ACTUAL FINAL PAYMENT WILL BE FOR ALL PRINCIPAL AND
              ACCRUED INTEREST NOT YET PAID, TOGETHER WITH ANY OTHER UNPAID
              AMOUNTS UNDER THIS NOTE.

The annual interest rate for this Note is computed on a 365/360 basis; that is,
by applying the ratio of the annual interest rate over a year of 360 days,
multiplied by the outstanding principal balance, multiplied by the actual number
of days the principal balance is outstanding. Borrower will pay Lender at
Lender's address shown above or at such other place as Lender may designate in
writing. Unless otherwise agreed or required by applicable law, payments will be
applied first to any unpaid collection costs and any late charges, then to any
unpaid interest, and any remaining amount to principal.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from
time to time based on changes in an independent index which is the Prime rate as
published in the Wall Street Journal. When a range of rates has been published,
the lower of the rates will be used (the "Index"). The Index is not necessarily
the lowest rate charged by Lender on its loans. If the Index becomes unavailable
during the term of this loan, Lender may designate a substitute index after
notice to Borrower. Lender will tell Borrower the current Index rate upon
Borrower's request. Borrower understands that Lender may make loans based on
other rates as well. The interest rate change will not occur more often than
each day. THE INDEX CURRENTLY IS 8.500% PER ANNUM. THE INTEREST RATE OR RATES TO
BE APPLIED TO THE UNPAID PRINCIPAL BALANCE OF THIS NOTE WILL BE THE RATE OR
RATES SET FORTH ABOVE IN THE "PAYMENT" SECTION. NOTICE: Under no circumstances
will the interest rate on this Note be more than the maximum rate allowed by
applicable law. Whenever increases occur in the interest rate, Lender, at its
option, may do one or more of the following: (a) increase Borrower's payments to
ensure Borrower's loan will pay off by its original final maturity date, (b)
increase Borrower's payments to cover accruing interest, (c) increase the number
of Borrower's payments, and (d) continue Borrower's payments at the same amount
and increase Borrower's final payment.

PREPAYMENT; MINIMUM INTEREST CHARGE. In any event, even upon full prepayment of
this Note, Borrower understands that Lender is entitled to a MINIMUM INTEREST
CHARGE OF $40.00. Other than Borrower's obligation to pay any minimum interest
charge, Borrower may pay without penalty all or a portion of the amount owed
earlier than it is due. Early payments will not, unless agreed to by Lender in
writing, relieve Borrower of Borrower's obligation to continue to make payments
under the payment schedule. Rather, they will reduce the principal balance due
and may result in Borrower making fewer payments.

LATE CHARGE. If a payment is 10 DAYS OR MORE LATE, Borrower will be charged
5.000% OF THE REGULARLY SCHEDULED PAYMENT OR $50.00, WHICHEVER IS GREATER.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this Note or
any agreement related to this Note, or in any other agreement or loan Borrower
has with Lender. (c) Borrower defaults under any loan, extension of credit,
security agreement, purchase or sales agreement, or any other agreement, in
favor of any other creditor or person that may materially affect any of
Borrower's property or Borrower's ability to repay this Note or perform
Borrower's obligations under this Note or any of the Related Documents. (d) Any
representation or statement made or furnished to Lender by Borrower or on
Borrower's behalf is false or misleading in any material respect either now or
at the time made or furnished. (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor tries
to take any of Borrower's property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with Lender.
(g) Any guarantor dies or any of the other events described in this default
section occurs with respect to any guarantor of this Note. (h) A material
adverse change occurs in Borrower's financial condition, or Lender believes the
prospect of payment or performance of the Indebtedness is impaired. (i) Lender
in good faith deems itself insecure.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest immediately due, without
notice, and then Borrower will pay that amount. Upon default, including failure
to pay upon final maturity, Lender, at its option, may also, if permitted under
applicable law, increase the variable interest rate on this Note to 24.000% per
annum. The interest rate will not exceed the maximum rate permitted by
applicable law. Lender may hire or pay someone else to help collect this Note if
Borrower does not pay. Borrower also will pay Lender that amount. This includes,
subject to any limits under applicable law, Lender's attorneys' fees and
Lender's legal expenses whether or not there is a lawsuit, including attorneys'
fees and legal expenses for bankruptcy proceedings (including efforts to modify
or vacate any automatic stay or injunction), appeals, and any anticipated
post-judgment collection services. If not prohibited by applicable law, Borrower
also will pay any court costs, in addition to

<PAGE>   10
all other sums provided by law. THIS NOTE HAS BEEN DELIVERED TO LENDER AND
ACCEPTED BY LENDER IN THE STATE OF COLORADO. IF THERE IS A LAWSUIT, BORROWER
AGREES UPON LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE COURTS OF EL
PASO COUNTY, THE STATE OF COLORADO. LENDER AND BORROWER HEREBY WAIVE THE RIGHT
TO ANY JURY TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY EITHER
LENDER OR BORROWER AGAINST THE OTHER. (INITIAL HERE _________) THIS NOTE SHALL
BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
COLORADO.

DISHONORED ITEM FEE. Borrower will pay a fee to Lender of $17.00 if Borrower
makes a payment on Borrower's loan and the check or preauthorized charge with
which Borrower pays is later dishonored.

interest in, and hereby assigns, conveys, delivers, pledges, and transfers to

without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA and Keogh accounts,
and all trust accounts for which the grant of a security interest would be
prohibited by law. Borrower authorizes Lender, to the extent permitted by
applicable law, to charge or setoff all sums owing on this Note against any and
all such accounts.

GENERAL PROVISIONS. This Note is payable on demand. The inclusion of specific
default provisions or rights of Lender shall not preclude Lender's right to

OBLIGATIONS OF GRANTOR. Grantor warrants and covenants to Lender as follows:

     PERFECTION OF SECURITY INTEREST. Grantor agrees to execute such financing
     statements and to take whatever other actions are requested by Lender to
     perfect and continue Lender's security interest in the Collateral. Upon
     request of Lender, Grantor will deliver to Lender any and all of the
     documents evidencing or constituting the Collateral, and Grantor will note
     Lender's interest upon any and all chattel paper if not delivered to Lender
     for possession by Lender. Grantor hereby appoints Lender as its irrevocable
     attorney-in-fact for the purpose of executing any documents necessary to
     perfect or to continue the security interest granted in this Agreement.
     Lender may at any time, and without further authorization from Grantor,
     file a carbon, photographic or other reproduction of any financing
     statement or of this Agreement for use as a financing statement. Grantor
     will reimburse Lender for all expenses for the perfection and the
     continuation of the perfection of Lender's security interest in the
     Collateral. Grantor promptly will notify Lender before any change in
     Grantor's name including any change to the assumed business names of
     Grantor.

     NO VIOLATION. The execution and delivery of this Agreement will not violate
     any law or agreement governing Grantor or to which Grantor is a party, and
     its certificate or articles of incorporation and bylaws do not prohibit any
     term or condition of this Agreement.

     ENFORCEABILITY OF COLLATERAL. To the extent the Collateral consists of
     accounts, chattel paper, or general intangibles, the Collateral is
     enforceable in accordance with its terms, is genuine, and complies with
     applicable laws concerning form, content and manner of preparation and
     execution, and all persons appearing to be obligated on the Collateral have
     authority and capacity to contract and are in fact obligated as they appear
     to be on the Collateral. At the time any account becomes subject to a
     security interest in favor of Lender, the account shall be a good and valid
     account representing an undisputed, bona fide indebtedness incurred by the
     account debtor, for merchandise held subject to delivery instructions or
     theretofore shipped or delivered pursuant to a contract of sale, or for
     services theretofore performed by Grantor with or for the account debtor;
     there shall be no setoffs or counterclaims against any such account; and no
     agreement under which any deductions or discounts may be claimed shall have
     been made with the account debtor except those disclosed to Lender in
     writing.

     REMOVAL OF COLLATERAL. Grantor shall keep the Collateral (or to the extent
     the Collateral consists of intangible property such as accounts, the
     records concerning the Collateral) at Grantor's address shown above, or at
     such other locations as are acceptable to Lender. Except in the ordinary
     course of its business, including the sales of inventory, Grantor shall not
     remove the Collateral from its existing locations without the

Loan No 1014868                     (Continued)


     prior written consent of Lender. To the extent that the Collateral consists
     of vehicles, or other titled property, Grantor shall not take or permit any
     action which would require application for certificates of title for the
     vehicles outside the State of Colorado, without the prior written consent
     of Lender.

     TRANSACTIONS INVOLVING COLLATERAL. Except for inventory sold or accounts
     collected in the ordinary course of Grantor's business, Grantor shall not
     sell, offer to sell, or otherwise transfer or dispose of the Collateral.
     Grantor shall not pledge, mortgage, encumber or otherwise permit the
     Collateral to be subject to any lien, security interest, encumbrance, or
     charge, other than the security interest provided for in this Agreement,
     without the prior written consent of Lender. This includes security
     interests even if junior in right to the security interests granted under
     this Agreement. Unless waived by Lender, all proceeds from any disposition
     of the Collateral (for whatever reason) shall be held in trust for Lender
     and shall not be commingled with any other funds; provided however, this
     requirement shall not constitute consent by Lender to any sale or other
     disposition. Upon receipt, Grantor shall immediately deliver any such
     proceeds to Lender.

     TITLE. Grantor represents and warrants to Lender that it holds good and
     marketable title to the Collateral, free and clear of all liens and
     encumbrances except for the lien of this Agreement. No financing statement
     covering any of the Collateral is on file in any public office other than
     those which reflect the security interest created by this Agreement or to
     which Lender has specifically consented. Grantor shall defend Lender's
     rights in the Collateral against the claims and demands of all other
     persons.

     COLLATERAL SCHEDULES AND LOCATIONS. As often as Lender shall require, and
     insofar as the Collateral consists of accounts, Grantor shall deliver to
     Lender schedules of such Collateral, including such information as Lender
     may require, including without limitation names and addresses of account
     debtors and agings of accounts. Insofar as the Collateral consists of
     equipment, Grantor shall deliver to Lender, as often as Lender shall
     require, such lists, descriptions, and designations of such Collateral as
     Lender may require to identify the nature, extent, and location of such
     Collateral. Such information shall be submitted for Grantor and each of its
     subsidiaries or related companies.

     MAINTENANCE AND INSPECTION OF COLLATERAL. Grantor shall maintain all
     tangible Collateral in good condition and repair. Grantor will not commit
     or permit damage to or destruction of the Collateral or any part of the
     Collateral. Lender and its designated representatives and agents shall have
     the right at all reasonable times to examine, inspect, and audit the
     Collateral wherever located. Grantor shall immediately notify Lender of all
     cases involving the return, rejection, repossession, loss or damage of or
     to any Collateral; of any request for credit or adjustment or of any other
     dispute arising with respect to the Collateral; and generally of all
     happenings and events affecting the Collateral or the value or the amount
     of the Collateral.

     TAXES, ASSESSMENTS AND LIENS. Grantor will pay when due all taxes,
     assessments and liens upon the Collateral, its use or operation, upon this
     Agreement, upon any promissory note or notes evidencing the Indebtedness,
     or upon any of the other Related Documents. Grantor may withhold any such
     payment or may elect to contest any lien if Grantor is in good faith
     conducting an appropriate proceeding to contest the obligation to pay and
     so long as Lender's interest in the Collateral is not jeopardized in
     Lender's sole opinion. If the Collateral is subjected to a lien which is
     not discharged within fifteen (15) days, Grantor shall deposit with Lender
     cash, a sufficient corporate surety bond or other security satisfactory to
     Lender in an amount adequate to provide for the discharge of the lien plus
     any interest, costs, attorneys' fees or other charges that could accrue as
     a result of foreclosure or sale of the Collateral. In any contest Grantor
     shall defend itself and Lender and shall satisfy any final adverse judgment
     before enforcement against the Collateral. Grantor shall name Lender as an
     additional obligee under any surety bond furnished in the contest
     proceedings.

     COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS. Grantor shall comply promptly
     with all laws, ordinances, rules and regulations of all governmental
     authorities, now or hereafter in effect, applicable to the ownership,
     production, disposition, or use of the Collateral. Grantor may contest in
     good faith any such law, ordinance or regulation and withhold compliance
     during any proceeding, including appropriate appeals, so long as Lender's
     interest in the Collateral, in Lender's opinion, is not jeopardized.

     HAZARDOUS SUBSTANCES. Grantor represents and warrants that the Collateral
     never has been, and never will be so long as this Agreement remains a lien
     on the Collateral, used for the generation, manufacture, storage,
     transportation, treatment, disposal, release or threatened release of any
     hazardous waste or substance, as those terms are defined in the
     Comprehensive Environmental Response, Compensation, and Liability Act of
     1980, as amended, 42 U.S.C. Section 9601, et seq. ("CERCLA"), the Superfund
     Amendments and Reauthorization Act of 1986, Pub. L. No. 99-499 ("SARA"),
     the Hazardous Materials Transportation Act, 49 U.S.C. Section 1801, et
     seq., the Resource Conservation and Recovery Act, 42 U.S.C. Section 6901,
     et seq., or other applicable state or Federal laws, rules, or regulations
     adopted pursuant to any of the foregoing. The terms "hazardous waste" and
     "hazardous substance" shall also include, without limitation, petroleum and
     petroleum by-products or any fraction thereof and asbestos. The
     representations and warranties contained herein are based on Grantor's due
     diligence in investigating the Collateral for hazardous wastes and
     substances. Grantor hereby (a) releases and waives any future claims
     against Lender for indemnity or contribution in the event Grantor becomes
     liable for cleanup or other costs under any such laws, and (b) agrees to
     indemnify and hold harmless Lender against any and all claims and losses
     resulting from a breach of this provision of this Agreement. This
     obligation to indemnify shall survive the payment of the Indebtedness and
     the satisfaction of this Agreement.

     MAINTENANCE OF CASUALTY INSURANCE. Grantor shall procure and maintain all
     risks insurance, including without limitation fire, theft and liability
     coverage together with such other insurance as Lender may require with
     respect to the Collateral, in form, amounts, coverages and basis reasonably
     acceptable to Lender and issued by a company or companies reasonably
     acceptable to Lender. Grantor, upon request of Lender, will deliver to
     Lender from time to time the policies or certificates of insurance in form
     satisfactory to Lender, including stipulations that coverages will not be
     cancelled or diminished without at least ten (10) days' prior written
     notice to Lender and not including any disclaimer of the insurer's
     liability for failure to give such a notice. Each insurance policy also
     shall include an endorsement providing that coverage in favor of Lender
     will not be impaired in any way by any act, omission or default of Grantor
     or any other person. In connection with all policies covering assets in
     which Lender holds or is offered a security interest, Grantor will provide
     Lender with such loss payable or other endorsements as Lender may require.
     In no event shall the insurance be in an amount less than the amount agreed
     upon in the Agreement to Provide Insurance. If Grantor at any time fails to
     obtain or maintain any insurance as required under this Agreement, Lender
     may (but shall not be obligated to) obtain such insurance as Lender deems
     appropriate, including if it so chooses "single interest insurance," which
     will cover only Lender's interest in the Collateral.

     APPLICATION OF INSURANCE PROCEEDS. Grantor shall promptly notify Lender of
     any loss or damage to the Collateral. Lender may make proof of loss if
     Grantor fails to do so within fifteen (15) days of the casualty. All
     proceeds of any insurance on the Collateral, including accrued proceeds
     thereon, shall be held by Lender as part of the Collateral. If Lender
     consents to repair or replacement of the damaged or destroyed Collateral,
     Lender shall, upon satisfactory proof of expenditure, pay or reimburse
     Grantor from the proceeds for the reasonable cost of repair or restoration.
     If Lender does not consent to repair or replacement of the Collateral,
     Lender shall retain a sufficient amount of the proceeds to pay all of the
     Indebtedness, and shall pay the balance to Grantor. Any proceeds which have
     not been disbursed within six (6) months after their receipt and which
     Grantor has not committed to the repair or restoration of the Collateral
     shall be used to prepay the Indebtedness.

     INSURANCE RESERVES. Lender may require Grantor to maintain with Lender
     reserves for payment of insurance premiums, which reserves shall be created
     by monthly payments from Grantor of a sum estimated by Lender to be
     sufficient to produce, at least fifteen (15) days before the premium due
     date, amounts at least equal to the insurance premiums to be paid. If
     fifteen (15) days before payment is due, the reserve funds are
     insufficient, Grantor shall upon demand pay any deficiency to Lender. The
     reserve funds shall be held by Lender as a general deposit and shall
     constitute a non-interest-bearing account which Lender may satisfy by
     payment of the insurance premiums required to be paid by Grantor as they
     become due. Lender does not hold the reserve funds in trust for Grantor,
     and Lender is not the agent of Grantor for payment of the insurance
     premiums required to be paid by Grantor. The responsibility for the payment
     of premiums shall remain Grantor's sole responsibility.

     INSURANCE REPORTS. Grantor, upon request of Lender, shall furnish to Lender
     reports on each existing policy of insurance showing such information as
     Lender may reasonably request including the following: (a) the name of the
     insurer; (b) the risks insured; (c) the amount of the policy; (d) the
     property insured; (e) the then current value on the basis of which
     insurance has been obtained and the manner of determining that value; and
     (f) the expiration date of the policy. In addition, Grantor shall upon
     request by Lender (however not more often than annually) have an
     independent appraiser satisfactory to Lender determine, as applicable, the
     cash value or replacement cost of the Collateral.

GRANTOR'S RIGHT TO POSSESSION AND TO COLLECT ACCOUNTS. Until default and except
as otherwise provided below with respect to accounts, Grantor may have
possession of the tangible personal property and beneficial use of all the
Collateral and may use it in any lawful manner not inconsistent with this
Agreement or the Related Documents, provided that Grantor's right to possession
and beneficial use shall not apply to any Collateral where possession of the
Collateral by Lender is required by law to perfect Lender's security interest in
such Collateral. Until otherwise notified by Lender, Grantor may collect any of
the Collateral consisting of accounts. At any time and even though no Event of
Default exists, Lender may exercise its rights to collect the accounts and to
notify account debtors to make payments directly to Lender for application to
the Indebtedness.

Loan No 1014868                     (Continued)




If Lender at any time has possession of any Collateral, whether before or after
an Event of Default, Lender shall be deemed to have exercised reasonable care in
the custody and preservation of the Collateral if Lender takes such action for
that purpose as Grantor shall request or as Lender, in Lender's sole discretion,
shall deem appropriate under the circumstances, but failure to honor any request
by Grantor shall not of itself be deemed to be a failure to exercise reasonable
care. Lender shall not be required to take any steps necessary to preserve any
rights in the Collateral against prior parties, nor to protect, preserve or
maintain any security interest given to secure the Indebtedness.

EXPENDITURES BY LENDER. If not discharged or paid when due, Lender may (but
shall not be obligated to) discharge or pay any amounts required to be
discharged or paid by Grantor under this Agreement, including without limitation
all taxes, liens, security interests, encumbrances, and other claims, at any
time levied or placed on the Collateral. Lender also may (but shall not be
obligated to) pay all costs for insuring, maintaining and preserving the
Collateral. All such expenditures incurred or paid by Lender for such purposes
will then bear interest at the rate charged under the Note from the date
incurred or paid by Lender to the date of repayment by Grantor. All such
expenses shall become a part of the Indebtedness and, at Lender's option, will
(a) be payable on demand, (b) be added to the balance of the Note and be
apportioned among and be payable with any installment payments to become due
during either (i) the term of any applicable insurance policy or (ii) the
remaining term of the Note, or (c) be treated as a balloon payment which will be
due and payable at the Note's maturity. This Agreement also will secure payment
of these amounts. Such right shall be in addition to all other rights and
remedies to which Lender may be entitled upon the occurrence of an Event of
Default.

EVENTS OF DEFAULT. Each of the following shall constitute an Event of Default
under this Agreement:

     DEFAULT ON INDEBTEDNESS. Failure of Grantor to make any payment when due on
     the Indebtedness.

     OTHER DEFAULTS. Failure of Grantor to comply with or to perform any other
     term, obligation, covenant or condition contained in this Agreement or in
     any of the Related Documents or in any other agreement between Lender and
     Grantor.

     DEFAULT IN FAVOR OF THIRD PARTIES. Should Borrower or any Grantor default
     under any loan, extension of credit, security agreement purchase or sales
     agreement, or any other agreement, in favor of any other creditor or person
     that may materially affect any of Borrower's property or Borrower's or any
     Grantor's ability to repay the Loans or perform their respective
     obligations under this Agreement or any of the Related Documents.

     FALSE STATEMENTS. Any warranty, representation or statement made or
     furnished to Lender by or on behalf of Grantor under this Agreement, the
     Note or the Related Documents is false or misleading in any material
     respect, either now or at the time made or furnished.

     DEFECTIVE COLLATERALIZATION. This Agreement or any of the Related Documents
     ceases to be in full force and effect (including failure of any collateral
     documents to create a valid and perfected security interest or lien) at any
     time and for any reason.

     INSOLVENCY. The dissolution or termination of Grantor's existence as a
     going business, the insolvency of Grantor, the appointment of a receiver
     for any part of Grantor's property, any assignment for the benefit of
     creditors, any type of creditor workout, or the commencement of any
     proceeding under any bankruptcy or insolvency laws by or against Grantor.

     CREDITOR OR FORFEITURE PROCEEDINGS. Commencement of foreclosure or
     forfeiture proceedings, whether by judicial proceeding, self-help,
     repossession or any other method, by any creditor of Grantor or by any
     governmental agency against the Collateral or any other collateral securing
     the Indebtedness. This includes a garnishment of any of Grantor's deposit
     accounts with Lender.

     EVENTS AFFECTING GUARANTOR. Any of the preceding events occurs with respect
     to any Guarantor of any of the Indebtedness or such Guarantor dies or
     becomes incompetent.

     ADVERSE CHANGE. A material adverse change occurs in Grantor's financial
     condition, or Lender believes the prospect of payment or performance of the
     Indebtedness is impaired.

     INSECURITY. Lender, in good faith, deems itself insecure.

RIGHTS AND REMEDIES ON DEFAULT. If an Event of Default occurs under this
Agreement, at any time thereafter, Lender shall have all the rights of a secured
party under the Colorado Uniform Commercial Code. In addition and without
limitation, Lender may exercise any one or more of the following rights and
remedies:

     ACCELERATE INDEBTEDNESS. Lender may declare the entire Indebtedness,
     including any prepayment penalty which Grantor would be required to pay,
     immediately due and payable, without notice.

     ASSEMBLE COLLATERAL. Lender may require Grantor to deliver to Lender all or
     any portion of the Collateral and any and all certificates of title and
     other documents relating to the Collateral. Lender may require Grantor to
     assemble the Collateral and make it available to Lender at a place to be
     designated by Lender. Lender also shall have full power to enter upon the
     property of Grantor to take possession of and remove the Collateral. If the
     Collateral contains other goods not covered by this Agreement at the time
     of repossession, Grantor agrees Lender may take such other goods, provided
     that Lender makes reasonable efforts to return them to Grantor after
     repossession.

     SELL THE COLLATERAL. Lender shall have full power to sell, lease, transfer,
     or otherwise deal with the Collateral or proceeds thereof in its own name
     or that of Grantor. Lender may sell the Collateral at public auction or
     private sale. Unless the Collateral threatens to decline speedily in value
     or is of a type customarily sold on a recognized market, Lender will give
     Grantor reasonable notice of the time after which any private sale or any
     other intended disposition of the Collateral is to be made. The
     requirements of reasonable notice shall be met if such notice is given at
     least ten (10) days before the time of the sale or disposition. All
     expenses relating to the disposition of the Collateral, including without
     limitation the expenses of retaking, holding, insuring, preparing for sale
     and selling the Collateral, shall become a part of the Indebtedness secured
     by this Agreement and shall be payable on demand, with interest at the Note
     rate from date of expenditure until repaid.

     APPOINT RECEIVER. To the extent permitted by applicable law, Lender shall
     have the following rights and remedies regarding the appointment of a
     receiver: (a) Lender may have a receiver appointed as a matter of right,
     (b) the receiver may be an employee of Lender and may serve without bond,
     and (c) all fees of the receiver and his or her attorney shall become part
     of the Indebtedness secured by this Agreement and shall be payable on
     demand, with interest at the Note rate from date of expenditure until
     repaid. The receiver may be appointed by a court of competent jurisdiction
     upon ex parte application and without notice, notice being expressly
     waived.

     COLLECT REVENUES, APPLY ACCOUNTS. Lender, either itself or through a
     receiver, may collect the payments, rents, income, and revenues from the
     Collateral. Lender may at any time in its discretion transfer any
     Collateral into its own name or that of its nominee and receive the
     payments, rents, income, and revenues therefrom and hold the same as
     security for the Indebtedness or apply it to payment of the Indebtedness in
     such order of preference as Lender may determine. Insofar as the Collateral
     consists of accounts, general intangibles, insurance policies, instruments,
     chattel paper, choses in action, or similar property, Lender may demand,
     collect, receipt for, settle, compromise, adjust, sue for, foreclose, or
     realize on the Collateral as Lender may determine, whether or not
     Indebtedness or Collateral is then due. For these purposes, Lender may, on
     behalf of and in the name of Grantor, receive, open and dispose of mail
     addressed to Grantor; change any address to which mail and payments are to
     be sent; and endorse notes, checks, drafts, money orders, documents of
     title, instruments and items pertaining to payment, shipment, or storage of
     any Collateral. To facilitate collection, Lender may notify account debtors
     and obligors on any Collateral to make payments directly to Lender.

     OBTAIN DEFICIENCY. If Lender chooses to sell any or all of the Collateral,
     Lender may obtain a judgment against Grantor for any deficiency remaining
     on the Indebtedness due to Lender after application of all amounts received
     from the exercise of the rights provided in this Agreement. Grantor shall
     be liable for a deficiency even if the transaction described in this
     subsection is a sale of accounts or chattel paper.

     OTHER RIGHTS AND REMEDIES. Lender shall have all the rights and remedies of
     a secured creditor under the provisions of the Uniform Commercial Code, as
     may be amended from time to time. In addition, Lender shall have and may
     exercise any or all other rights and remedies it may have available at law,
     in equity, or otherwise.

     CUMULATIVE REMEDIES. All of Lender's rights and remedies, whether evidenced
     by this Agreement or the Related Documents or by any other writing, shall
     be cumulative and may be exercised singularly or concurrently. Election by
     Lender to pursue any remedy shall not exclude pursuit

Loan No 1014868                     (Continued)



     of any other remedy, and an election to make expenditures or to take action
     to perform an obligation of Grantor under this Agreement, after Grantor's
     failure to perform, shall not affect Lender's right to declare a default
     and to exercise its remedies.

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of
this Agreement:

     AMENDMENTS. This Agreement, together with any Related Documents,
     constitutes the entire understanding and agreement of the parties as to the
     matters set forth in this Agreement. No alteration of or amendment to this
     Agreement shall be effective unless given in writing and signed by the
     party or parties sought to be charged or bound by the alteration or
     amendment.

     APPLICABLE LAW. This Agreement has been delivered to Lender and accepted by
     Lender in the State of Colorado. If there is a lawsuit, Grantor agrees upon
     Lender's request to submit to the jurisdiction of the courts of the State
     of Colorado. Lender and Grantor hereby waive the right to any jury trial in
     any action, proceeding, or counterclaim brought by either Lender or Grantor
     against the other. (INITIAL HERE      ) This Agreement shall be governed by
     and construed in accordance with the laws of the State of Colorado.

     ATTORNEYS' FEES; EXPENSES. Grantor agrees to pay upon demand all of
     Lender's costs and expenses, including attorneys' fees and Lender's legal
     expenses, incurred in connection with the enforcement of this Agreement.
     Lender may pay someone else to help enforce this Agreement, and Grantor
     shall pay the costs and expenses of such enforcement. Costs and expenses
     include Lender's attorneys' fees and legal expenses whether or not there is
     a lawsuit, including attorneys' fees and legal expenses for bankruptcy
     proceedings (and including efforts to modify or vacate any automatic stay
     or injunction), appeals, and any anticipated post-judgment collection
     services. Grantor also shall pay all court costs and such additional fees
     as may be directed by the court.

     CAPTION HEADINGS. Caption headings in this Agreement are for convenience
     purposes only and are not to be used to interpret or define the provisions
     of this Agreement.

     NOTICES. All notices required to be given under this Agreement shall be
     given in writing, may be sent by telefacsimile (unless otherwise required
     by law), and shall be effective when actually delivered or when deposited
     with a nationally recognized overnight courier or deposited in the United
     States mail, first class, postage prepaid, addressed to the party to whom
     the notice is to be given at the address shown above. Any party may change
     its address for notices under this Agreement by giving formal written
     notice to the other parties, specifying that the purpose of the notice is
     to change the party's address. To the extent permitted by applicable law,
     if there is more than one Grantor, notice to any Grantor will constitute
     notice to all Grantors. For notice purposes, Grantor will keep Lender
     informed at all times of Grantor's current address(es).

     POWER OF ATTORNEY. Grantor hereby appoints Lender as its true and lawful
     attorney-in-fact, irrevocably, with full power of substitution to do the
     following: (a) to demand, collect, receive, receipt for, sue and recover
     all sums of money or other property which may now or hereafter become due,
     owing or payable from the Collateral; (b) to execute, sign and endorse any
     and all claims, instruments, receipts, checks, drafts or warrants issued in
     payment for the Collateral; (c) to settle or compromise any and all claims
     arising under the Collateral, and, in the place and stead of Grantor, to
     execute and deliver its release and settlement for the claim; and (d) to
     file any claim or claims or to take any action or institute or take part in
     any proceedings, either in its own name or in the name of Grantor, or
     otherwise, which in the discretion of Lender may seem to be necessary or
     advisable. This power is given as security for the Indebtedness, and the
     authority hereby conferred is and shall be irrevocable and shall remain in
     full force and effect until renounced by Lender.

     SEVERABILITY. If a court of competent jurisdiction finds any provision of
     this Agreement to be invalid or unenforceable as to any person or
     circumstance, such finding shall not render that provision invalid or
     unenforceable as to any other persons or circumstances. If feasible, any
     such offending provision shall be deemed to be modified to be within the
     limits of enforceability or validity; however, if the offending provision
     cannot be so modified, it shall be stricken and all other provisions of
     this Agreement in all other respects shall remain valid and enforceable.

     SUCCESSOR INTERESTS. Subject to the limitations set forth above on transfer
     of the Collateral, this Agreement shall be binding upon and inure to the
     benefit of the parties, their successors and assigns.

     WAIVER. Lender shall not be deemed to have waived any rights under this
     Agreement unless such waiver is given in writing and signed by Lender. No
     delay or omission on the part of Lender in exercising any right shall
     operate as a waiver of such right or any other right. A waiver by Lender of
     a provision of this Agreement shall not prejudice or constitute a waiver of
     Lender's right otherwise to demand strict compliance with that provision or
     any other provision of this Agreement. No prior waiver by Lender, nor any
     course of dealing between Lender and Grantor, shall constitute a waiver of
     any of Lender's rights or of any of Grantor's obligations as to any future
     transactions. Whenever the consent of Lender is required under this
     Agreement, the granting of such consent by Lender in any instance shall not
     constitute continuing consent to subsequent instances where such consent is
     required and in all cases such consent may be granted or withheld in the
     sole discretion of Lender.

GRANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS COMMERCIAL SECURITY
AGREEMENT, AND GRANTOR AGREES TO ITS TERMS. THIS AGREEMENT IS DATED JANUARY 16,
1998.

</TABLE>

DESCRIPTION OF EXISTING INDEBTEDNESS. The Promissory Note dated January 16,
1998, in the original principal amount of $2,000,000.00.

DESCRIPTION OF COLLATERAL. Accounts Receivable, Machinery/Equipment, and
Furniture/Fixtures.

DESCRIPTION OF CHANGE IN TERMS. The original maturity date of January 16, 1999,
has been changed to reflect an extended maturity date of January 16, 2000.

PROMISE TO PAY. USA.NET, INC. AND ALL COSIGNERS SIGNING THIS AGREEMENT (REFERRED
TO IN THIS AGREEMENT INDIVIDUALLY AND COLLECTIVELY AS "BORROWER") JOINTLY AND
SEVERALLY PROMISE TO PAY TO VECTRA BANK OF COLORADO, N.A. DBA STATE BANK AND
TRUST OF COLORADO SPRINGS ("LENDER"), OR ORDER, IN LAWFUL MONEY OF THE UNITED
STATES OF AMERICA, THE PRINCIPAL AMOUNT OF TWO MILLION & 00/100 DOLLARS
($2,000,000.00) OR SO MUCH AS MAY BE OUTSTANDING, TOGETHER WITH INTEREST ON THE
UNPAID OUTSTANDING PRINCIPAL BALANCE OF EACH ADVANCE. INTEREST SHALL BE
CALCULATED FROM THE DATE OF EACH ADVANCE UNTIL REPAYMENT OF EACH ADVANCE.

PAYMENT. BORROWER WILL PAY THIS LOAN ON DEMAND, OR IF NO DEMAND IS MADE, IN ONE
PAYMENT OF ALL OUTSTANDING PRINCIPAL PLUS ALL ACCRUED UNPAID INTEREST ON JANUARY
16, 2000. IN ADDITION, BORROWER WILL PAY REGULAR MONTHLY PAYMENTS OF ACCRUED
UNPAID INTEREST BEGINNING FEBRUARY 16, 1999, AND ALL SUBSEQUENT INTEREST
PAYMENTS ARE DUE ON THE SAME DAY OF EACH MONTH AFTER THAT. The annual interest
rate for this Agreement is computed on a 365/360 basis; that is, by applying the
ratio of the annual interest rate over a year of 360 days, multiplied by the
outstanding principal balance, multiplied by the actual number of days the
principal balance is outstanding. Borrower will pay Lender at Lender's address
shown above or at such other place as Lender may designate in writing. Unless
otherwise agreed or required by applicable law, payments will be applied first
to any unpaid collection costs and any late charges, then to any unpaid
interest, and any remaining amount to principal.

VARIABLE INTEREST RATE. The interest rate on this Agreement is subject to change
from time to time based on changes in an independent index which is the Prime
rate as published in the Wall Street Journal. When a range of rates has been
published, the lower of the rates will be used (the "Index"). The Index is not
necessarily the lowest rate charged by Lender on its loans. If the Index becomes
unavailable during the term of this loan, Lender may designate a substitute
Index after notice to Borrower. Lender will tell Borrower the current Index rate
upon Borrower's request. Borrower understands that Lender may make loans based
on other rates as well. The interest rate change will not occur more often than
each day. THE INDEX CURRENTLY IS 7.750% PER ANNUM. THE INTEREST RATE TO BE
APPLIED TO THE UNPAID PRINCIPAL BALANCE OF THIS AGREEMENT WILL BE AT A RATE
EQUAL TO THE INDEX, RESULTING IN AN INITIAL RATE OF 7.750% PER ANNUM. NOTICE:
Under no circumstances will the interest rate on this Agreement be more than the
maximum rate allowed by applicable law.

PREPAYMENT; MINIMUM INTEREST CHARGE. In any event, even upon full prepayment of
this Agreement, Borrower understands that Lender is entitled to a MINIMUM
INTEREST CHARGE OF $40.00. Other than Borrower's obligation to pay any minimum
interest charge, Borrower may pay without penalty all or a portion of the amount
owed earlier than it is due. Early payments will not, unless agreed to by Lender
in writing, relieve Borrower of Borrower's obligation to continue to make
payments of accrued unpaid interest. Rather, they will reduce the principal
balance due.

LATE CHARGE. If a payment is 10 DAYS OR MORE LATE, Borrower will be charged
5.000% OF THE REGULARLY SCHEDULED PAYMENT OR $50.00, WHICHEVER IS GREATER.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this
Agreement or any agreement related to this Agreement, or in any other agreement
or loan Borrower has with Lender. (c) Borrower defaults under any loan,
extension of credit, security agreement, purchase or sales agreement, or any
other agreement, in favor of any other creditor or person that may materially
affect any of Borrower's property or Borrower's ability to repay this Note or
perform Borrower's obligations under this Note or any of the Related Documents.
(d) Any representation or statement made or furnished to Lender by Borrower or
on Borrower's behalf is false or misleading in any material respect either now
or at the time made or furnished. (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor tries
to take any of Borrower's property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with Lender.
(g) Any guarantor dies or any of the other events described in this default
section occurs with respect to any guarantor of this Agreement. (h) A material
adverse change occurs in Borrower's financial condition, or Lender believes the
prospect of payment or performance of the Indebtedness is impaired. (i) Lender
in good faith deems itself insecure.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Agreement and all accrued unpaid interest immediately due,
without notice, and then Borrower will pay that amount. Upon default, including
failure to pay upon final maturity, Lender, at its option, may also, if
permitted under applicable law, increase the variable interest rate on this
Agreement to 24.000% per annum. The interest rate will not exceed the maximum
rate permitted by applicable law. Lender may hire or pay someone else to help
collect this Agreement if Borrower does not pay. Borrower also will pay Lender
that amount. This includes, subject to any limits under applicable law, Lender's
attorneys' fees and Lender's legal expenses whether or not there is a lawsuit,
including attorneys' fees and legal expenses for bankruptcy proceedings
(including efforts to modify or vacate any automatic stay or injunction),
appeals, and any anticipated post-judgment collection services. If not
prohibited by applicable law, Borrower also will pay any court costs, in
addition to all other sums provided by law. THIS AGREEMENT HAS BEEN DELIVERED TO
LENDER AND ACCEPTED BY LENDER IN THE STATE OF COLORADO. IF THERE IS A LAWSUIT,
BORROWER AGREES UPON LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE
COURTS OF EL PASO COUNTY, THE STATE OF COLORADO. LENDER AND BORROWER HEREBY
WAIVE THE RIGHT TO ANY JURY TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM
BROUGHT BY EITHER LENDER OR BORROWER AGAINST THE OTHER. (INITIAL HERE__________)
SUBJECT TO THE PROVISIONS ON ARBITRATION, THIS AGREEMENT SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF COLORADO.

DISHONORED ITEM FEE. Borrower will pay a fee to Lender of $17.00 if Borrower
makes a payment on Borrower's loan and the check or preauthorized charge with
which Borrower pays is later dishonored.

RIGHT OF SETOFF. Borrower grants to Lender a contractual security interest in,
and hereby assigns, conveys, delivers, pledges, and transfers to Lender all
Borrower's right, title and interest in and to, Borrower's accounts with Lender
(whether checking, savings, or some other account), including without limitation
all accounts held jointly with someone else and all accounts Borrower may open
in the future, excluding however all IRA and Keogh accounts, and all trust
accounts for which the grant of a security interest would be prohibited by law.
Borrower authorizes Lender, to the extent permitted by applicable law, to charge
or setoff all sums owing on this Agreement against any and all such accounts.

LINE OF CREDIT. This Agreement evidences a revolving line of credit. Advances
under this Agreement, as well as directions for payment from Borrower's
accounts, may be requested orally or in writing by Borrower or by an authorized
person. Lender may, but need not, require that all oral requests be confirmed in
writing. The following party or parties are authorized to request advances under
the line of credit until Lender receives from Borrower at Lender's address shown
above written notice of revocation of their authority: JOHN W. STREET,
PRESIDENT, CEO. Borrower agrees to be liable for all sums either: (a) advanced
in accordance with the instructions of an authorized person or (b) credited to
any of Borrower's accounts with Lender. The unpaid principal balance owing on
this Agreement at any time may be evidenced by endorsements on this Agreement or
by Lender's internal records, including daily computer print-outs. Lender will
have no obligation to advance funds under this Agreement if: (a) Borrower or any
guarantor is in default under the terms of this Agreement or any agreement that
Borrower or any guarantor has with Lender, including any agreement made in
connection with the signing of this Agreement; (b) Borrower or any guarantor
ceases doing business or is insolvent; (c) any guarantor seeks, claims or
otherwise attempts to limit, modify or revoke such guarantor's guarantee of this
Agreement or any other loan with Lender; (d) Borrower has applied funds provided
pursuant to this Agreement for purposes other than those authorized by Lender;
or (e) Lender in good faith deems itself insecure under this Agreement or any
other agreement between Lender and Borrower.

ARBITRATION. LENDER AND BORROWER AGREE THAT ALL DISPUTES, CLAIMS AND
CONTROVERSIES BETWEEN THEM, WHETHER INDIVIDUAL, JOINT, OR CLASS BY NATURE,
ARISING FROM THIS AGREEMENT OR OTHERWISE, INCLUDING WITHOUT LIMITATION CONTRACT
AND TORT DISPUTES, SHALL BE ARBITRATED PURSUANT TO THE RULES OF THE AMERICAN

includes, without limitation, obtaining an injunction or a temporary restraining
order; invoking a power of sale under any deed of trust or mortgage; obtaining a
writ of attachment or imposition of a receiver; or exercising any rights
relating to personal property, including taking or disposing of such property
with or without judicial process pursuant to Article 9 of the Uniform Commercial
Code. Any disputes, claims, or controversies concerning the lawfulness or
reasonableness of any act, or exercise of any right, concerning any collateral
securing this Agreement, including any claim to rescind, reform, or otherwise
modify any agreement relating to the collateral securing this Agreement, shall
also be arbitrated, provided however that no arbitrator shall have the right or
the power to enjoin or restrain any act of any party. Judgment upon any award
rendered by any arbitrator may be entered in any court having jurisdiction.
Nothing in this Agreement shall preclude any party from seeking equitable relief
from a court of competent jurisdiction. The statute of limitations, estoppel,
waiver, laches, and similar doctrines which would otherwise by applicable in an
action brought by a party shall be applicable in any arbitration proceeding, and
the commencement of an arbitration proceeding shall be deemed the commencement
of an action for these purposes. The Federal Arbitration Act shall apply to the
construction, interpretation, and enforcement of this arbitration provision.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms of
the original obligation or obligations, including all agreements evidenced or
securing the obligation(s), remain unchanged and in full force and effect.
Consent by Lender to this Agreement does not waive Lender's right to strict
performance of the obligation(s) as changed, nor obligate Lender to make any
future change in terms. Nothing in this Agreement will constitute a satisfaction
of the obligation(s). It is the intention of Lender to retain as liable parties
all makers and endorsers of the original obligation(s), including accommodation
parties, unless a party is expressly released by Lender in writing. Any maker or
endorser, including accommodation makers, will not be released by virtue of this
Agreement. If any person who signed the original obligation does not sign this
Agreement below, then all persons signing below acknowledge that this Agreement
is given conditionally, based on the representation to Lender that the
non-signing party consents to the changes and provisions of this Agreement or
otherwise will not be released by it. This waiver applies not only to any
initial extension, modification or release, but also to all such subsequent
actions.

THIRTY-DAY ZERO BALANCE PROVISION. For one consecutive thirty-day period during
the term of this renewal, the outstanding principal balance of this revolving
line of credit must remain at $0.00.

MISCELLANEOUS PROVISIONS. This Agreement is payable on demand. The inclusion of
specific default provisions or rights of Lender shall not preclude Lender's
right to declare payment of this Agreement on its demand. Lender may delay or
forgo enforcing any of its rights or remedies under this Agreement without
losing them. Borrower and any other person who signs, guarantees or endorses
this Agreement, to the extent allowed by law, waive presentment, demand for
payment, protest and notice of dishonor. Upon any change in the terms of this
Agreement, and unless otherwise expressly stated in writing, no party who signs
this Agreement, whether as maker, guarantor, accommodation maker or endorser,
shall be released from liability. All such parties agree that Lender may renew
or extend (repeatedly and for any length of time) this loan, or release any
party or guarantor or collateral; or impair, fail to realize upon or perfect
Lender's security interest in the collateral; and take any other action deemed
necessary by Lender without the consent of or notice to anyone. All such parties
also agree that Lender may modify this loan without the consent of or notice to
anyone other than the party with whom the modification is made. The obligations
under this Agreement are joint and several.

PRIOR TO SIGNING THIS AGREEMENT, EACH BORROWER READ AND UNDERSTOOD ALL THE
PROVISIONS OF THIS AGREEMENT, INCLUDING THE VARIABLE INTEREST RATE PROVISIONS.

                                 LEASE AGREEMENT


         THIS LEASE AGREEMENT, made and entered into as of the 11th day of
September, 1997, by and between THE CHAPEL HILLS OFFICE BUILDING, A COLORADO
JOINT VENTURE (hereinafter referred to as the "LANDLORD"), and USA.NET, INC.
(hereinafter referred to as the "TENANT").

                              W I T N E S S E T H:

         IN CONSIDERATION of the mutual promises and covenants contained herein,
the parties hereto agree as follows:

         1. PREMISES. LANDLORD hereby leases to TENANT and TENANT hereby rents
from LANDLORD, the space (hereinafter called the "Leased Premises" in an office
building located at 1155 Kelly Johnson Boulevard, in the City of Colorado
Springs, State of Colorado (hereinafter called the "Project") situated as shown
on Exhibit A attached hereto and made a part hereof. Any measurements specified
on Exhibit A are from the exterior of the outside walls of the Project and to
the center of the interior walls provided however included in Tenant's space is
that area inset in front of the entrance door to allow the door to swing towards
the public corridor. The approximate boundaries and location of the Leased
Premises are outlined in red on Exhibit A. For purposes of this Lease, the
parties agree that the Leased Premises shall be deemed to contain approximately
15,000* leasable square feet (the "Leasable Square Footage"), such Leasable
Square Footage calculated by the formula: the approximate actual or usable
square footage occupied by the Tenant multiplied by the factor 1.1433 to account
for the tenants shared use of the common areas of the Project. The exact
Leasable Square Footage shall be determined solely by the Landlord's architect
and shall be measured in accordance with the rules of B.O.M.A. standard of
measurement for multi-tenancy. This Lease shall be adjusted after the
determination of exact Leasable Square Footage to reflect the exact Leasable
Square Footage and all other items related to the Leasable Square Footage shall
be adjusted accordingly. The purpose of the site plan shown on Exhibit A is to
show the approximate location of the Leased Premises. Landlord reserves the
right at any time to relocate or make additions to the various common areas,
automobile parking areas, and other areas of the Project.

         2. USE. TENANT covenants and agrees to use the Leased Premises for the
purpose of conducting therein office use for GENERAL OFFICE USE and for no other
purpose whatsoever, without the prior written consent of the LANDLORD.

         3. TERM. The term of this Lease shall commence on October 15, 1997 OR
fifteen (15) days after LANDLORD notifies TENANT that the space is available to
TENANT for occupancy and fixturing, or when TENANT commences business on the
premises, whichever shall occur first and shall continue for a period of 60 full
consecutive months (the "Term"); expiring on the last day of October, 2002.
LANDLORD and TENANT shall execute, acknowledge and deliver a written statement
specifying the commencement date of the Term once it is determined pursuant to
the terms of this Lease Agreement.

         4.  RENT.

A. TENANT shall pay to LANDLORD annually for the Term of the Lease, without
prior demand thereof, at its address set forth below, the sum as defined below
as the Minimum Rent for each year of the Term of this Lease.

The Minimum Rent for the Term of the Lease shall be calculated by the following
formula: the Leasable Square Footage multiplied by the absolute net rate per
square foot as indicated below, in equal monthly installments, in advance on or
before the 1st day of each month of the Lease Term. The absolute net rate for
each year of the Term shall be: SEE ADDENDUM

All such Rent shall be paid without any set-off, counterclaim or deduction
whatsoever and without demand therefore being made. Minimum rent for any partial
month shall be prorated on a daily basis.

B. Additional Rent, which is estimated at Five Dollars Seventy Five Cents
($5.75) per Leasable square foot for the first year of the Term, shall be
payable by TENANT in monthly installments as are billed by LANDLORD at the
beginning of the Lease for a twelve (12) month period, each such installment
being due on the first day of each month but to be received from the TENANT no
later than the 10th of each month (per paragraph 4(c) herein). The monthly
payments to be made by TENANT shall be adjusted and revised to compensate for
any overpayment of underpayment made by TENANT in such preceding twelve (12)
month period. Within ninety (90) days after the end of each twelve (12) month
period, LANDLORD shall, upon request, make available LANDLORD'S records relating
to the operating costs for such preceding period. At the end of this Lease any
overages collected as Additional Rent which are to the credit of TENANT shall be
reimbursed to TENANT as credit against its Minimum Rent. Additional Rent
includes LANDLORD'S "operating costs" defined in Exhibit "E" (B), page 23 of
this Lease.

C. TENANT shall pay LANDLORD a $100.00 service charge for all monthly rent
payments not received by the 10th day of the month for which they are payable.
Said service charge is to partially cover extra expense involved in handling
delinquent payments. In addition to the above, any rental and other sums payable
hereunder by TENANT which are not paid within ten (10) days after the due date
shall bear interest at the rate of the annual prime rate of BANC ONE plus five
percent per annum or the highest amount legally allowed by law, whichever is
less, from the date due to the date paid.

D. All Rent, Additional Rent and other sums due to the LANDLORD, unless
specifically provided, are due and payable in advance on or before the first day

LANDLORD at 1155 Kelly Johnson Boulevard, Colorado Springs, Colorado, U.S.A. or
such other place as LANDLORD may in writing advise TENANT.

         5. DEPOSITS. It is further agreed that TENANT, concurrently with the
execution of this Lease shall deposit with LANDLORD, and will keep on deposit at
all times during the Term of this Lease, the sum of $15,000.00, as security for
the payment by TENANT of the rent and other charges herein agreed to be paid,
and for the faithful performance of all the terms, conditions and covenants of
this Lease. If, at any time during the Term of this Lease, TENANT shall be in
default in the performance of any provision of this Lease, LANDLORD, shall have
the right to use said deposit, or so much thereof as is necessary in payment of
any rental in default, in reimbursement of any expense incurred by LANDLORD
hereunder and in payment of any damages incurred by LANDLORD by reason of
TENANTS's default. In any such events, TENANT shall, on written demand of
LANDLORD, forthwith remit to LANDLORD a sufficient amount in cash to restore
said deposit to its original amount. If TENANT shall have fully and faithfully
complied with all the provisions of this Lease, said deposit shall be refunded
to TENANT within sixty (60) days after the termination of this Lease. LANDLORD
shall have the right to commingle said deposit with other funds of LANDLORD.
LANDLORD shall deliver the balance of said funds, if any, deposited here by
TENANT to the acquirer of LANDLORD's interest in the Project and, in the event
of a transfer of sale, thereafter. LANDLORD shall be discharged from further
liability with respect to such deposit.

         6. The "Lease" consists of this Lease Agreement, the General Terms and
Conditions of Lease Agreement attached hereto, Exhibits attached hereto, and any
subsequent written Modification of Lease executed by the parties hereto in
amending the terms hereof.

IN WITNESS WHEREOF, said LANDLORD and TENANT have caused this Lease to be
executed the day and year first above written.

                 GENERAL TERMS AND CONDITIONS OF LEASE AGREEMENT

         1.  CONSTRUCTION OF IMPROVEMENTS.

                  A. LANDLORD shall construct certain portions of the Leased
Premises for TENANT's use and occupancy. All work to be performed and paid for
by LANDLORD shall be listed and described in Exhibit "B" attached hereto.

                  B. Any work defined in this Lease which is TENANT's obligation
to complete at its expense and to be performed by TENANT must first be approved
in writing by LANDLORD and shall be constructed in a good and workmanlike
manner, free from any liens for labor and materials. TENANT agrees to indemnify
LANDLORD and hold LANDLORD harmless against any loss, liability or damage
resulting from such work, and to furnish LANDLORD with a certificate of
insurance for general liability and workman's compensation insurance. TENANT
shall promptly pay for any work done initially or subsequently in or about its
Leased Premises, and will not permit or suffer any mechanic's lien to attach to
its Leased Premises, and shall promptly cause any claim for any such lien to be
released, or to secure to LANDLORD's satisfaction, in the event TENANT desires
to contest any such claim.

         2.  AVAILABILITY OF PREMISES.

                  A. The Leased Premises shall be completed, within sixty (60)
days of approval of working drawings. Rent commences upon occupancy of the
Leased Premises within the Building. If, for any reason, the Leased Premises
shall not be ready or available for occupancy on the date contemplated, this
Lease shall nevertheless continue in full force and effect, and TENANT shall
have no right to rescind, cancel or terminate the same and LANDLORD shall not be
liable for damages, if any, sustained by said TENANT on account of failure to
obtain possession on the date contemplated and in such event the rent for the
Leased Premises shall not commence until the term commences as defined in the
Lease Agreement Paragraph 3.

                  B. Preparation for occupancy of the Leased Premises by TENANT
shall be based on work being done to the Leased Premises in accordance with
"Exhibit B". TENANT, shall provide LANDLORD a list of any deficiencies upon
occupancy, and LANDLORD shall promptly proceed to correct those items.

         3.  PROJECT CONSTRUCTION.

                  A. Anything in this Lease to the contrary notwithstanding,
providing such cause is not due to the willful act or neglect of the LANDLORD,
the LANDLORD shall not be deemed in default with respect to the performance of
any of the terms, covenants and conditions of this Lease if same shall be due to
any strike, lockout, civil commotion, war-like operation, invasion, rebellion,
hostilities, military or usurped power, sabotage, governmental regulations or
controls, inability to obtain any materials, services, zoning, Project permits
or financing, through Act of God or other cause beyond the control of the
LANDLORD.

         4.  FINANCIAL RESPONSIBILITY.

                  TENANT agrees to furnish a financial statement in a form
acceptable to LANDLORD upon TENANT's execution of this Lease.

         5.  PARKING.

                  Project shall maintain approximately (3.34) unassigned parking
spaces, per One Thousand (1,000) leasable square feet, which shall be available
for TENANT's use. There are (19) visitor parking spaces available located in the
easterly parking areas which shall be for the use of Tenant's visitors on a
non-exclusive basis.

         6.  FIRE OR CASUALTY.

                  It is agreed that if, during the continuance of this Lease,
the Leased Premises shall be so damaged by fire or other casualty, not arising
from the fault or negligence of the TENANT, or those in its employ, so that the
Leased Premises shall thereby be rendered untenantable, then and in such case,
the rent herein reserved, or a just and proportionate part thereof, according to
the nature and extent of the damage which has been sustained, shall be abated
until the Leased Premises shall have been duly repaired and restored, which work
of repair and restoration shall be done with all reasonable diligence; provided
however, that should Tenant be in default at the time same occurs LANDLORD shall
have no such obligation. LANDLORD's obligation to repair and restore shall be
limited to a basic building and the replacement of any interior work which may
have been installed at LANDLORD's cost. In no event in the case of any such
destruction shall LANDLORD be required to repair or restore TENANT's stock in
trade, leasehold improvements, fixtures, furnishings, or floor coverings and
equipment. In the case the Project shall be destroyed so that the Leased
Premises are not restorable within one hundred twenty (120) days in the sole
judgment of the LANDLORD, LANDLORD shall have the right to cancel this Lease and
end the Term hereof, and in case of such cancellation, the rent, and any other
monies due and owing to LANDLORD, shall be paid by TENANT to the date TENANT
vacates the Leased Premises, and all further obligations upon the part of either
party hereto shall cease, and the estate hereby created shall thereupon
terminate. In the event the Leased Premises are damaged by fire or other
casualty during the last year of the Term of the Lease to an extent which
renders the Leased Premises untenantable, the LANDLORD may, at LANDLORD's
option, within thirty (30) days following the day of such fire or other
casualty, 

                                       4

<PAGE>   6

immediately terminate this Lease and be relieved of any obligation to rebuild or
repair the Leased Premises.

         7.  SERVICES AND EXPENSES.

                  The services of the LANDLORD and the payment by TENANT for
said services and of operational expenses are described in Exhibit "E". TENANT's
failure to comply with any one of the provisions of Exhibit "E" shall constitute
a breach of the terms of this Lease in the manner as if the same were contained
herein as general terms and conditions.

         8.  ALTERATIONS AND CARE OF PREMISES.

                  A. TENANT will not alter the exterior of the Leased Premises
(including glass and signs, if applicable) and shall have no right to make any
change, alteration, or addition to the Leased Premises without the prior written
consent of LANDLORD; all costs of such work shall be paid promptly by TENANT so
as to prevent the assertion of any liens for labor or materials. LANDLORD
reserves the right to make any alteration on the Leased Premises.

                  B. The TENANT agrees that it will take good care of the Leased
Premises, fixtures and appurtenances, and suffer no waste or injury, that it
will make all repairs to the Leased Premises, fixtures, and appurtenances
necessitated by the fault of the TENANT, its agents, employees and guests,
invitees and licensees, that it will not do, or permit anything to be done in
the Leased Premises which will in any way increase the fire insurance premium on
the Project, or conflict with the fire insurance policies on the Project; that
it will defend and save harmless the LANDLORD from any liability arising from
injury to person or property caused by any act or omission of TENANT, its
agents, employees or guests; and that it will surrender the Leased Premises at
the expiration of the Term (or the sooner termination thereof for any reason) in
as good condition as they were at the beginning of the Term, ordinary wear and
tear excepted.

                  C. All alterations, additions, erections or improvements on or
in the Leased Premises at the expiration of this Lease, except trade fixtures,
shall, at the option of the LANDLORD, be and become a part of the Leased
Premises, and shall, at the option of the LANDLORD, remain upon and be
surrendered with the Leased Premises as a part thereof at the termination of
this Lease. Should TENANT fail to remove any furniture or fixtures or personal
property of any kind, then same shall be considered as abandoned and become the
property of the LANDLORD. In the event LANDLORD may desire TENANT to remove
additions or alterations, TENANT, at his expense, shall, upon expiration of this
Lease, restore the Leased Premises to the same and as good order and condition
as when the same were entered upon by TENANT, ordinary wear and tear excepted
and in default thereof, LANDLORD may effect such removals and repairs and TENANT
shall pay LANDLORD the cost thereof, with interest at the rate of one and one
half percent (1.5%) percent per month commencing ten days after billing by
LANDLORD. Improvements constructed by the LANDLORD are not subject to this 
section.

         9.  DEFAULT AND REMEDIES.

                  A. The following events shall be deemed to be events of
default by TENANT under this Lease:

                           (i) TENANT shall have failed to pay any installment
of rent or any other charge provided herein, or any portion thereof when the
same shall be due and payable; or

                           (ii) TENANT shall have failed to comply with any
other provisions of this Lease and shall not cure such failure within thirty
(30) days after LANDLORD, by written notice, has informed TENANT of such
noncompliance (in the case of a default which cannot with due diligence be cured
within a period of thirty (30) days, TENANT shall have such additional time to
cure same as may be reasonably necessary, provided TENANT proceeds promptly and
with due diligence to cure such default after receipt of said notice; or

                           (iii) TENANT or its guarantor, if any, shall file in
any court a petition in bankruptcy or insolvency or for the reorganization or
arrangement within the meaning of the Bankruptcy Act as amended, or under any
future Bankruptcy Act for the same or similar relief, or for the appointment of
a receiver or trustee of all or a portion of TENANT's property; or

                           (iv) An involuntary petition of the kind referred to
in subparagraph (iii) herein shall be filed against TENANT or its guarantor, if
any, and such petition shall not be vacated or withdrawn within sixty (60) days
after the date of filing thereof; or

                           (v) TENANT or its guarantor, if any, shall make an
assignment for the benefit of creditors; or

                           (vi) TENANT or its guarantor, if any, shall be
adjudicated a bankrupt; or

                           (vii) A receiver shall be appointed for the property
of TENANT or its guarantor by a court of competent jurisdiction; or

                           (viii) TENANT shall cease to conduct its normal
business operations in the premises or shall vacate or abandon the premises and
leave same vacated or abandoned for a period of ten (10) days; or




                                       5

<PAGE>   7


                           (ix) TENANT shall do or permit to be done anything
which creates a lien upon the premises which is not paid or discharged promptly;
then LANDLORD, upon three (3) days' written notice to TENANT may elect either
(i) to cancel and terminate this Lease, or (ii) to terminate TENANT's right to
possession only without terminating the Lease.

                  B. In the event of election under (ix) above to terminate
TENANT's right to possession only, LANDLORD may, at LANDLORD's option, enter
into the premises and take and hold possession thereof, without such entry into
possession terminating this Lease or releasing TENANT in whole or in part from
TENANT's obligation to pay the rent hereunder for the full stated Term. Upon
such reentry with fifteen (15) days written notice, LANDLORD may remove all
persons and property from the premises and such property may be removed and
stored in a public warehouse or elsewhere at the cost of, and for the account of
TENANT, all without service of notice or resort to legal process and without
being deemed guilty of trespass, or becoming liable for any loss or damage which
may be occasioned thereby. Upon and after entry into possession without
termination of the Lease, LANDLORD, may but need not relet the premises, or any
part thereof, for the account of TENANT, to any person, firm or corporation,
other than TENANT, for such rent, for such time and upon such terms as LANDLORD,
in LANDLORD's sole discretion, shall determine, and LANDLORD shall not be
required to accept any tenant offered by TENANT or to observe any instruction
given by TENANT about such reletting. In any such case, LANDLORD may make
repairs and redecorate the premises to the extent deemed by LANDLORD necessary
or desirable, and TENANT shall, upon demand pay the costs thereof, together with
LANDLORD's expense of reletting, including commissions. If the consideration
collected by LANDLORD upon any such reletting for TENANT's account, and after
deducting all expenses incident thereto, including brokerage fees and legal
expenses is not sufficient to pay monthly the full amount of the rent provided
in this Lease, TENANT shall pay to LANDLORD the amount of each monthly
deficiency upon demand. In the event that LANDLORD shall have terminated
TENANT's right to possession only, LANDLORD shall have the right to cancel and
terminate this Lease by serving five (5) days written notice on TENANT of such
further election and to pursue any remedy at law or in equity that may be
available to LANDLORD.

                  C. If TENANT shall fail to remove all personal property upon
the abandonment of the leased premises or upon the termination of this Lease for
any cause whatsoever, the LANDLORD, at its option, may remove the same in any
manner that it shall choose and store the said effects without liability to the
TENANT for loss thereof in any public or private warehouse, and the TENANT
agrees to pay the LANDLORD on demand any and all expenses incurred in such
removal, including court costs and attorney's fees and storage charges on such
personal property for any length of time the personal property shall be in
storage; or the LANDLORD, at its option, without notice, may sell said personal
property, or any of the same, at private sale and without legal process, for
such prices as the LANDLORD may obtain, and apply the proceeds of such sale upon
any amounts due under this Lease from the TENANT to the LANDLORD and upon the
expense incidental to the removal, storage, and sale of the personal property,
rendering the surplus, if any, to the TENANT.

                  D. In the event of any breach hereunder by TENANT, LANDLORD
may immediately or at any time thereafter, without notice, cure such breach for
the account and at the expense of TENANT. If LANDLORD at any time by reason of
such breach is compelled to pay, or elects to pay, any sum of money or do any
act which will require the payment of any sum of money, or is compelled to incur
any expense, including reasonable attorney's fees, the sum or sums so paid by
LANDLORD, with interest thereon at the rate of one and one half percent (1.5%)
per month from the date of payment thereof, shall be deemed to be due from
TENANT to LANDLORD on the first day of each month following the payment of such
respective sums or expenses.

                  E.  [THIS SECTION DELETED]

                  F. If at any time or times hereafter, if by reason of default,
eviction or other action at law or equity, LANDLORD employ counsel for advice
with respect to this Lease or any related landlord-tenant law issue, or employs
counsel to intervene, file an eviction, complaint, notice, answer, motion or
other pleading in any suit or proceeding relating to this Lease Agreement or the
tenancy relationship, or to attempt to collect rents under or to enforce this
Lease Agreement against TENANT, its assign(s) or subtenant(s), then, if any of
such events, the prevailing party shall be entitled to all reasonable legal
expenses arising from any such action.

                  G. This lease shall be construed under Colorado Law.

                  H. TENANT waives and disclaims any present or future right to
withhold any rental payment or any other payment due under this Lease, or to
set-off in any action for rental, against any obligation of LANDLORD, however
incurred.

                  I. Should LANDLORD be in default under the terms of this
Lease, LANDLORD shall have reasonable and adequate time in which to cure the
same after written notice to LANDLORD by TENANT.

         10.  ASSIGNMENT OR SUBLETTING.

                  A. It is agreed that neither the Leased Premises nor any part
thereof shall be sublet, nor shall this Lease be assigned by TENANT without the
written consent of the LANDLORD having been first obtained, such consent shall
not be unreasonably withheld by LANDLORD. No assignment for the benefit of
creditors, or by operation of law, shall be effective to transfer any rights to
an assignee without the written consent of the LANDLORD having been first
obtained.


                                       6

<PAGE>   8

                  B. It is agreed that if this Lease be assigned, or if the
Leased Premises or any part thereof be sublet or occupied by anyone other than
TENANT, LANDLORD may collect rent from the assignee, subtenant or occupant, and
apply the net amount collected to the rent herein specified, and no such
collection shall be deemed a waiver of the covenant herein against assignment
and subletting, or the acceptance of the assignee, subtenant or occupant as
TENANT, or a release of TENANT from the complete performance by TENANT of the
covenants herein contained on the part of TENANT to be performed.
Notwithstanding any assignment or sublease, TENANT shall remain fully liable on
this Lease and shall not be released from performing any of the terms, covenants
and conditions of this Lease.

                  C. LANDLORD shall in any case have the right, at its option,
to terminate this Lease, rather than have it sublet or assigned.

                  D. If at any time during the Term of this Lease any part or
all of the corporate shares of a corporate TENANT or any part or all of the
interests of a partnership or joint venture TENANT shall be transferred by sale,
assignment, bequest, inheritance, operation of law, or other disposition so as
to result in a change in the present effective voting control of TENANT by the
person or persons owning a majority of said corporate shares or partnership or
joint venture interests on the date of this Lease, TENANT shall promptly notify
LANDLORD in writing of such change. LANDLORD, upon receipt of said written
notice, shall not unreasonably withhold approval of such change in interest. If,
however, LANDLORD determines that such change in interest shall materially
affect the terms of this lease, it may terminate this lease at its sole option,
by giving TENANT Ninety (90) days written notice of such termination.

         11.  ENCUMBRANCES.

                  A. It is agreed that this Lease is subject and subordinate to
the lien of any trust deeds or mortgages now on, or which at any time may be
made a lien upon the Leased Premises or the Project in which the Leased Premises
are situated, and to all advances made or hereafter to be made upon the security
thereof without any further action or consent being required.

                  B. At any time, and from time to time, TENANT agrees, upon
request in writing from LANDLORD, to execute, acknowledge and deliver to
LANDLORD a statement in writing certifying that this Lease is unmodified and in
full force and effect or if there have been modifications, that the same is in
full force and effect as modified and stating the modifications and the dates to
which rent, herein stipulated, and other charges have been paid.

                  C. In the event of any transfer or sale of the Leased Premises
by the LANDLORD, LANDLORD shall be and is hereby entirely freed and relieved of
all liability under any and all of its covenants and obligations contained in or
derived from this Lease arising out of any act, occurrence or omission occurring
after the Consummation of such transfer or sale. The acquirer, at such transfer
or sale or any subsequent transfer or sale of the Lease Premises, shall be
deemed, without any further agreement between the parties or their successors in
interest or between the parties and any such purchaser, to have assumed and
agreed to carry out any and all of the covenants and obligations of LANDLORD
hereunder; this lease shall become part of any change in ownership, from
LANDLORD to any Third Party, under the same terms and conditions hereof.

         12.  EMINENT DOMAIN.

                  A. If the whole of the Leased Premises shall be acquired or
condemned by eminent domain for any public or quasi-public use or purpose, then
the Term of this Lease shall cease and terminate as of the date of title vesting
in such proceeding and all rentals shall be paid up to that date and TENANT
shall have no claim against LANDLORD nor the condemning authority for the value
of any unexpired Term of this Lease. If any part of the Leased Premises shall be
acquired or condemned as aforesaid, and in the event that such partial taking or
condemnation shall render the Leased Premises unsuitable for the business of the
TENANT, then the Term of this Lease shall cease and terminate as of the date of
title vesting in such proceeding. TENANT shall neither have a claim against
LANDLORD nor against the condemning authority for the value of any unexpired
Term of this Lease and rent shall be adjusted to the date of such termination.
In the event of a partial taking or condemnation which is not extensive enough
to render the premises unsuitable for the business of the TENANT, the LANDLORD
shall promptly restore the Leased Premises to a condition comparable to its
condition at the time of such condemnation less the portion lost in the taking,
and this Lease shall continue in full force and effect without any reduction or
abatement of rent.

                  B. In the event of any condemnation or taking as aforesaid,
whether whole or partial, the TENANT shall not be entitled to any part of the
award paid for such condemnation and LANDLORD is to receive the full amount of
such award, the TENANT hereby expressly waiving any right or claim to any part
thereof. Although all damages in the event of condemnation are to belong to the
LANDLORD whether such damages are awarded as compensation for diminution in
value of the leasehold or to the fee of the Leased Premises, TENANT shall have
the right to claim and recover from the condemning authority, but not from
LANDLORD, such compensation as may be separately awarded or recoverable by
TENANT in TENANT's own right on account of any and all damage to TENANT's
business by reason of the condemnation and for or on account of any cost or loss
to which TENANT might be put in removing TENANT's merchandise, furniture,
fixtures, leasehold improvements and equipment.

         13.  MUTUAL WAIVER OF SUBROGATION.

                  Anything in this Lease to the contrary notwithstanding,
neither LANDLORD nor TENANT shall be liable to the other for any business
interruption or any loss or damage to property or injury to or death of persons
occurring on the Leased Premises or the adjoining properties, sidewalks, streets
or 



                                       7
<PAGE>   9

alleys, or in any manner growing out of or connected with TENANT's use and
occupation of, or LANDLORD's operation and maintenance of, the Leased Premises,
or the condition thereof, or of sidewalks, streets or alleys adjoining, caused
by the negligence or other fault of LANDLORD or TENANT or of their respective
agents, employees, subtenants, licensees or assignees, to the extent that such
business interruption or loss or damage to property or injury to or death of
persons is covered by or indemnified by proceeds received from insurance carried
by the other party (regardless of whether such insurance is payable to or
protects LANDLORD or TENANT or both) or for which such party is otherwise
reimbursed; and LANDLORD and TENANT each hereby respectively waives all right of
recovery against the other, its agents, employees, subtenants, licensees and
assignees, for any such loss or damage to property or injury to or death of
persons to the extent the same is covered or indemnified by proceeds received
from any such insurance, or for which reimbursement is otherwise received.
Nothing in this Paragraph contained shall be construed to impose any other or
greater liability upon either LANDLORD or TENANT than would have existed in the
absence of this Paragraph.

         14. ADDITIONAL COVENANTS. TENANT further covenants and agrees:

                  A. To comply with all lawful orders, building codes,
regulations and requirements issued by any Federal, State or Municipal
Governments, or any department or division thereof, insofar as the same are
applicable to its possession and occupancy of the Leased Premises. TENANT
further covenants not to use the Leased Premises for any purposes now or
hereafter prohibited by the Laws of the United States, the State of Colorado or
applicable ordinances; or for any improper or questionable purpose whatsoever.

                  B. That it will indemnify LANDLORD and save LANDLORD harmless
from each and every loss, cost, damage or expense arising out of any accident or
other occurrence causing injury to any person or property whomsoever or
whatsoever, and due directly or indirectly to the condition of the Leased
Premises or to the use or neglect of the Project premises, or any part thereof,
by said TENANT, or any person or persons holding under said TENANT, and will
indemnify and hold harmless said LANDLORD from all damages and penalties arising
out of any failure of TENANT, in any respect, to comply with all and any of the
requirements and provisions of this Lease; and shall hold LANDLORD harmless from
any penalty, damage and charge imposed for any violation of any laws, whether
occasioned by act or neglect of said TENANT, or by another or others in the
Leased Premises holding under or through TENANT. TENANT shall not hold or
attempt to hold LANDLORD liable for any injury or damage, either proximate or
otherwise; or liable for any injury or damage occasioned by defective wiring or
breakage or stoppage of plumbing or sewage upon the Leased Premises, whether
said breakage or stoppage results from freezing or otherwise. In the event, that
LANDLORD, in its acts or omissions, is found grossly negligent under this
section, said indemnification shall not apply.

                  C. That no assent, expressed or implied, to any breach of any
one or more of the covenants or agreements hereof, nor the delay of LANDLORD in
the assertion of any rights hereunder, shall be deemed to be taken to be a
waiver of any succeeding or other breach. The various rights, remedies, powers,
options and elections of LANDLORD reserved, expressed or contained in this Lease
are cumulative and no one of them shall be deemed to be exclusive of the others
or of such other rights, remedies, powers, options or elections as are now or
may hereafter be conferred upon LANDLORD by law.

                  D. To display no sign, advertisement, notice or other
lettering on any part of the outside of the Leased Premises or the Project of
which they form a part, or inside exterior glass, without, in each instance, the
prior written consent of LANDLORD, such consent may be arbitrarily withheld by
LANDLORD. No trade fixtures or other projections shall be attached to the
outside walls or roof of the Leased Premises without the prior written consent
of the LANDLORD, such consent may be arbitrarily withheld by LANDLORD. LANDLORD
is to provide a bronze strip suite entrance sign according to building standards
with lettering and wording approval by TENANT. Additionally, the lobby directory
strip will be in accordance with building standards with wording approved by
TENANT.

                  E. To permit LANDLORD to place a "For Rent" sign upon the
Leased Premises, only during the last 90 days of Lease term; and LANDLORD may,
at any reasonable hour of the day, enter into or upon, and go through and view
and inspect, the Leased Premises.

                  F. That no act or thing done by LANDLORD or LANDLORD's agents
during the Term hereof, or any extension thereof, shall be deemed an acceptance
of a surrender of the Leased Premises, and no agreement to accept such surrender
shall be valid unless in writing signed by LANDLORD.

                  G. No payment by TENANT, or receipt by LANDLORD, of a lesser
amount than the rent and other charges herein stipulated, shall be deemed to be
other than on account of the earliest stipulated rent, nor shall any endorsement
or statement on any check or any letter accompanying any check, or payment as
rent, be deemed an accord and satisfaction, and LANDLORD may accept such check
or payment without prejudice to LANDLORD's right to recover the balance of such
rent or pursue any other remedy available to LANDLORD.

                  H. That the exhibits or supplements, if any be hereto
attached, are made a part hereof and shall be binding upon the parties hereto,
and if any provision of said exhibits or supplements shall conflict in any
manner with any other provision of this Lease, the provision of the supplement
shall prevail.

                  I. That all the terms, conditions and covenants to be observed
and performed by the parties hereto shall be applicable and binding upon their
heirs, executors, administrators, successors and assigns.


                                        8

<PAGE>   10

                  J. That the invalidity or unenforceability of any provision of
this Lease shall not affect or impair the validity of any other provision. The
laws of the State of Colorado shall govern the interpretation, validity,
performance and enforcement of this Lease.

         15.  NO PARTNERSHIP, JOINT VENTURE OR AGENCY.

                  It is expressly understood that LANDLORD and TENANT are not
partners or joint venturers and that LANDLORD has no right, title or interest in
and to the business of TENANT, and that LANDLORD has no right to represent or
bind TENANT in any respect whatsoever, and that nothing herein contained shall
be deemed, held or construed as making LANDLORD a partner, joint venturer, or
associate of TENANT, nor as rendering LANDLORD liable for any debts, liabilities
or obligations incurred by TENANT. Neither is the relationship between LANDLORD
and TENANT that of Principal and Agent. It is expressly understood that the
relationship between the parties hereto is, and shall at all times, remain that
of LANDLORD and TENANT.

         16.  HOLDING OVER.

                  It is agreed that if, after the expiration of this Lease,
TENANT shall, without LANDLORD's consent, remain in possession of the Leased
Premises and shall continue to pay rent without written agreement as to such
possession, such TENANT shall be regarded as a tenant from month to month, at a
monthly rental, payable in advance, equal to two (2) times the monthly rental
for the last full month immediately prior to said expiration, and shall
otherwise be subject to all the terms and conditions of this Lease.

         17.  QUIET ENJOYMENT.

                  Upon payment by the TENANT of the rents and other charges
herein provided, and upon the observance and performance of all the covenants,
terms and conditions on TENANT's part to be observed and performed, TENANT shall
peaceably and quietly hold and enjoy the Leased Premises for the term hereby
leased without hindrance or interruption by LANDLORD or any other person or
persons lawfully or equitably claiming by, through or under the LANDLORD,
subject, nevertheless, to the terms and conditions of this Lease.

         18.  RULES AND REGULATIONS.

                  TENANT shall comply with all rules and regulations set forth
in Exhibit "F". Any violation of said rules shall be a failure to perform a
covenant of this Lease. LANDLORD shall have the right to make additions and
amendments to said regulations from time to time and such additions and
amendments shall be as binding on TENANT as if set forth herein.

         19.  FORCE MAJEURE.

                  In the event that either party shall be delayed or hindered in
or prevented from the performance of any act required hereunder by reason of
strikes, lockouts, riots, insurrection or war, then performance of such act
shall be excused for the period of the delay and the period for the performance
of any such act shall be extended for a period equivalent to the period of such
delay. The provisions of this section shall not operate to excuse TENANT from
prompt payment of Rents or any other payments required by the terms of this
Lease; however, LANDLORD agrees to abatement of rent after 30 days, only if any
act is substantially disruptive affecting all tenants and their ability to do
business.

         20.  RECORDING BY TENANT.

                  It is understood by the parties hereto that this Lease or any
memo thereof, shall not be recorded by TENANT without LANDLORD's written
permission.

         21.  NO OPTION.

                  The submission of this Lease for examination or execution does
not constitute a reservation of or option for the Leased Premises, and this
Lease becomes effective as a Lease only upon execution and delivery thereof by
LANDLORD and TENANT.

         22.  ATTORNMENT.

                  At the election of the encumbrancer, TENANT shall, in the
event of any foreclosure of any encumbrances attorn to the purchaser upon any
such foreclosure sale and recognize such purchaser as the LANDLORD. This lease
shall become part of any change in ownership, from LANDLORD to any Third Party
under the same terms and conditions hereof.

         23.  NOTICE.

                  Any notice which may be required to be given hereunder from
either of the parties to the other shall be in writing. Said notice may be
served personally or shall be deemed duly served by LANDLORD upon TENANT if
mailed by Certified Mail, Return Receipt Requested, with proper postage prepaid,
addressed to TENANT at the address at the Leased Premises hereby leased, and by
TENANT upon LANDLORD if mailed by Certified Mail, Return Receipt Requested, with
proper postage prepaid, addressed to LANDLORD at the address in Paragraph 4D of
Lease Agreement, or at such other address as either party may hereafter fix, by
notice in writing to the other.

         24.  REPRESENTATIONS.

                  TENANT acknowledges and agrees that it has not relied upon any
statements, representations, agreements or warranties except as are expressed
herein.

         25.  AMENDMENTS OR APPROVALS.

                  No amendment or modification of this Lease, or any approvals
or permissions of LANDLORD required under this Lease, shall be valid or binding
unless reduced to writing and executed by the parties hereto in the same manner
as the execution of this Lease.

         26.  GRAMMATICAL CHANGES.

                  Wherever the words "LANDLORD" and "TENANT" are used in this
indenture, they shall include "LANDLORD" and "TENANT's" and shall apply to
persons, both men and women, companies, associations, partnerships, corporations
and trusts.

         27.  ARTICLE HEADINGS.

                  It is agreed that the head notes or article headings are
inserted only as a matter of convenience and for reference, and in no way
define, limit or describe the scope or intent of this Lease.

                                   EXHIBIT "E"
                              SERVICES AND EXPENSES


         1. Notwithstanding any term in this Lease to the contrary, it is the
intent of the LANDLORD and TENANT that this Lease is an absolute net lease to
the LANDLORD with the TENANT paying its proportionate share of all costs of
operation of the Project including and not limited to the cost of managing,
operating, cleaning of common areas and tenant spaces per building standards as
may be determined by the LANDLORD from time to time, equipping, protecting,
lighting, relamping, repairing, replacing, heating, air conditioning, of all the
areas of the Project or any other costs reasonably related to the cost of the
operation of the Project. Such costs shall include, but shall not be limited to
utilities, supplies, janitorial services, management fees, employees' wages,
social security and unemployment insurance contributions, union benefits,
rubbish, snow and ice removal, maintenance and replacement of landscaping,
paving, parking lot striping and premiums for insurance.

The LANDLORD shall provide only those services specifically stated in this
Exhibit at the cost of the TENANT. TENANT covenants and agrees to procure all
other services and pay all other costs and expenses or reimburse LANDLORD should
LANDLORD elect to pay certain costs and expenses.

         2.  INSURANCE.

                  A. LANDLORD shall procure all risk coverage subject to
standard exclusions (including coverage for rental loss in connection with
damage and destruction covered by the said fire and extended coverage
insurance), liability, workman's compensation and other reasonably necessary
insurance on the Project. TENANT shall reimburse LANDLORD monthly, as Additional
Rent for its proportionate share of the actual net cost and expense to LANDLORD
of such insurance including losses due to deductible insurance of the LANDLORD.
TENANT's proportionate share of such costs shall be determined by Paragraph 7 of
this Exhibit. One-twelfth (1/12th) of the amount due shall be payable on the
first day of each month and added to the monthly rental. These amounts may be
based on an estimate until the actual premiums are available and then available
adjustments shall be made and any difference shall be payable based on TENANT's
actual share as determined. Said payment amount shall be modified annually, if
necessary, in order to accurately reflect the actual insurance premium payment.

                  B. TENANT shall maintain at its sole cost and expense fire and
extended coverage, vandalism, malicious mischief and special extended coverage
insurance in an amount adequate to cover the cost of replacement of all
furniture, fixtures, alterations, decorations, inventory, goods, merchandise,
improvements and equipment in the Leased Premises, whether supplied or owned by
the TENANT or by the LANDLORD in companies and form acceptable to LANDLORD. The
policy of insurance required to be obtained hereunder by TENANT shall provide
that any and all loss proceeds shall be payable to LANDLORD and TENANT as their
interest may appear and shall state that the insurer will not cancel or change
the insurance without first giving the LANDLORD twenty (20) days prior written
notice. A copy of the policy or a certificate of insurance shall be delivered to
the LANDLORD within thirty (30) days of TENANT's occupancy of the premises.

                  C. TENANT agrees that it will not keep, use, sell or offer for
sale upon the Leased Premises any article that may be prohibited by the
LANDLORD's form of fire insurance policy. TENANT agrees to pay any increase in
premiums for insurance that may be charged during the Term of tenants or
subtenants in the Project resulting from the presence, storage, use or sale of
equipment, materials, supplies, merchandise or other articles in or about the
Leased Premises, whether or not LANDLORD has consented to the same or not.

                  D. TENANT, shall for the entire Term hereof, keep in full
force and effect a policy of public liability and property damage insurance with
respect to the Leased Premises, hallways of Leased Premises, and the business
operated by TENANT and any subtenants of TENANT in the Leased Premises. The
limits of said policy shall be no less than One Million ($1,000,000.00) Dollars
combined single limit coverage for bodily injury and property damage liability.
The policy shall name LANDLORD, any person, firm, or corporation designated by
LANDLORD, and TENANT as the insured and shall state that the insurer will not
cancel or change the insurance without first giving the LANDLORD twenty (20)
days prior written notice. The insurance shall be with an insurance company
licensed to do business in the State of Colorado. A copy of the policy or a
certificate of insurance shall be delivered to LANDLORD within thirty (30) days
of TENANT's occupancy of the premises. TENANT shall increase the foregoing
limits if LANDLORD deems such increase is desirable to protect TENANT and
LANDLORD as well.

                  E. TENANT shall repair any damage that might be caused to the
Leased Premises in connection with breaking and entering of said Leased Premises
for the purpose of larceny.

                  F. TENANT shall maintain at its own cost and expense a
Standard Form of Worker's Compensation and Employer's Liability Insurance
covering all TENANT's employees for injury or illness suffered in the course of
or arising out of their employment, providing Statutory Worker's Compensation
benefits and Employer's Liability Limits of liability of not less than One
Hundred Thousand ($100,000.00) Dollars and TENANT shall show evidence of such
coverage.

         3.  UTILITIES.

                  A. TENANT shall be solely responsible for and shall promptly
pay its proportionate share per Paragraph 7 hereof, of all charges for heat,

                                       15

<PAGE>   17

the Leased Premises. Should LANDLORD elect to supply the water, gas, heat,
electricity or other utility used or consumed in the Leased Premises, TENANT
agrees to purchase and pay for same as Additional Rent provided such rate is no
higher than TENANT could obtain for like service from the utility company. In no
event shall LANDLORD be liable for an interruption or failure in the supply of
any such utilities to the Leased Premises.

                  B. TENANT agrees to install no electrical equipment which
overloads the lines or interferes with other equipment in the Project, or any
part thereof and if said lines are overloaded by such installation, to
immediately remedy the same at its own expense and to comply with all
requirements of the Insurance Underwriters or governmental authorities.

         4.  TAXES.

                  A. TENANT covenants and agrees to pay to LANDLORD, as
Additional Rent, that sum which is equal to TENANT's proportionate share as
determined in Paragraph 7 of this Exhibit of real estate taxes and special
assessments levied and imposed against the entire Project and payable by
LANDLORD. For the tax year in which this Lease commences or terminates, the
provisions hereof shall apply in the proportionate to which the number of months
the Leased Premises are occupied by TENANT bear to a full tax year. In addition
to the foregoing, TENANT shall be liable for all taxes levied against all
personal property, and trade fixtures placed by TENANT in or about the Leased
Premises, and for any tax increase due to improvements, additions or alterations
to the Leased Premises made during the Term of this Lease.

                  B. In the event that any tax or assessment other than real
estate, public utility or school zone tax is ever levied against the Project,
such as a rent, business or gross receipt tax or otherwise, said tax shall be
the sole responsibility of TENANT. TENANT shall pay the same as further
Additional Rent before any fine, penalty, interest or costs may be added thereto
for the nonpayment thereof.

         5.  MAINTENANCE AND REPAIR.

                  A. LANDLORD agrees to provide regular maintenance so as to
keep in good order, condition, and repair, foundations and structural portions
of the Leased Premises, except for any damage thereof caused by any act or
negligence of TENANT, its employees, invitees, agents, licensees, or
contractors. The LANDLORD shall not be responsible if TENANT is negligent to
make plumbing, electrical, or mechanical repairs or replacements or other
improvements of repairs of any kind upon the Leased Premises except as may be
expressly set out in this Lease. Any dispute between LANDLORD and TENANT as to
the LANDLORD's obligations under this Paragraph shall not excuse the payment of
rent or other performances by TENANT.

                  B. TENANT agrees that, from and after the date that possession
of the Leased Premises is delivered to the TENANT, and until the end of the Term
hereof, it will be responsible for its prorata share of payments of all repairs,
maintenance, and replacements to the Leased Premises other than those
specifically required to be performed by LANDLORD in Paragraph A above,

                  C. LANDLORD reserves the right to elect to provide certain
maintenance, repairs, and replacements, including preventative maintenance. In
the event of such election, TENANT shall pay its proportionate share of expenses
as determined in Paragraph 7 of this Exhibit.

damage caused by any act of gross negligence of LANDLORD, its employees or
agents. TENANT shall not be required to make structural repairs or alterations
which may be required by governmental rules, order or regulations unless

Premises. TENANT shall not permit or suffer the Leased Premises, or the walls or
the floors thereof to be endangered by overloading. All repairs, maintenance,
replacement or any other work required by this Paragraph shall be approved by
LANDLORD prior to commencement of such work.

                  E. Should any provision of this Paragraph 5 be inconsistent

                  C. TENANT shall pay LANDLORD, as Additional Rent, its
proportionate share of LANDLORD's Operating Costs. The TENANT's proportionate

monthly installments in such amounts as are estimated and billed by LANDLORD at
the beginning of a twelve (12) month period commencing and ending on dates
designated solely by LANDLORD, each such installment being due on the first day
of each month. The monthly payments to be made by TENANT shall be adjusted and
revised to compensate for any overpayment or underpayment made by TENANT in such
preceding twelve (12) month period. Within ninety (90) days after the end of
each twelve (12) month period, LANDLORD shall, upon request, make available
LANDLORD's records relating to LANDLORD Operating Costs for such preceding
period.

         7. PROPORTIONATE SHARE. TENANT's proportionate share of expenses or
other amounts shall be computed by multiplying said expense or amount by a
fraction, the numerator of which shall be the number of Leaseable Square Footage
of area in the Leased Premises leased by the TENANT and the denominator of which

         B. Tenant wishes to add certain space in the Project to the Leased
Premises, and Landlord has consented to that addition, subject to the terms and
conditions of this Amendment. All capitalized terms used in this Amendment but

                                    AGREEMENT

         In consideration of the recitals set forth above and the covenants
contained herein, Landlord and Tenant hereby agree as follows:

         1.       Expansion of Premises. The Leased Premises will be expanded as

be 25,209 square feet.

         2.       Term. Tenant's lease of Suite 301 will commence as of the date

                  3.2      Commencing January 1, 1999, and continuing through

                  3.3      In addition to Minimum Rent, Tenant will pay all

repainting; and (c) addition of an interior door to Suite 306, and any other
reasonable items, all subject to Tenant's reasonable approval, but at a total
cost not to exceed $5.00 per square foot of the Suite 301 Leasable Area. Except
as required by the preceding sentence, Tenant acknowledges that it has inspected
Suite 301, is familiar with its physical condition, and accepts Suite 301 in its
"As Is" condition. Tenant acknowledges and agrees that Landlord makes no
warranties, either explicit or implied, regarding the suitability of Suite 301
for any use or purpose.

         5.       Parking. Section 5 of the General Terms and Condition of Lease

         be available for Tenant's use on a non-exclusive basis with other
         tenants of the Project and visitors.

         6.       Broker's Commissions. Tenant and Landlord represent and
warrant to each other that there are no claims for brokerage commissions or
finder's fees in connection with this Amendment. Tenant agrees to indemnify
Landlord against and hold it harmless from all liabilities arising from any
claims of brokerage commissions and finder's fees made by any broker or finder
engaged by Tenant, and Landlord agrees to indemnify Tenant against and hold it

be binding upon and inure to the benefit of the parties hereto, their successors
and assigns.

         9.       Effect of Agreement. This Amendment will not constitute an
offer by Landlord nor will it be of any binding effect on Landlord until it is
signed by Landlord. This Amendment contains the entire agreement between the
parties relating to the matters discussed herein. Except as specifically set
forth in this Amendment, all provisions of the Lease remain in full force and

limitations contained in Section 10.6 hereof), Seller agrees to reimburse,
indemnify and hold harmless Buyer against and in respect of any and all
damages, losses, liabilities, costs and expenses incurred or suffered by Buyer

<PAGE>   8



reasonable detail the basis of such claim, action or suit and the facts
pertaining thereto. The failure of the indemnified party to promptly notify the
indemnifying party of such claim, action or suit after notice to the
indemnified party of such claim, action or suit shall not constitute a waiver
of its rights under this provision unless such failure to promptly notify the
indemnifying party shall have materially and adversely prejudiced the rights of
the indemnifying party in respect of such claim, action or suit.

                 (ii) ASSUMPTION OF DEFENSE. Following the notice described in
Section 10.3(i) above, the indemnifying party shall have ten (10) days to
notify the indemnified party that it intends to assume the defense of any

indemnifying party fails to give notice of the assumption of the defense of any
claim, action or suit that is indemnifiable hereunder within the time period
described in Section 10.3(ii) above, the indemnifying party shall no longer be
entitled to assume such defense and the indemnified party shall defend such
claim, action or suit, and, in such event, the indemnifying party shall
indemnify the indemnified party for all reasonable fees and expenses incurred
in connection therewith. The indemnifying party shall be entitled to
participate at its own expense and with its counsel in the defense of any
claim, action or suit, the defense of which it does not assume. Prior to
effectuating any compromise or settlement of any such claim, action or suit,
the indemnified party shall furnish the indemnifying party with written notice
of any proposed compromise or settlement in sufficient time to allow the
indemnifying party to act thereon. Following reasonable time after the giving
of such notice, the indemnified party shall be permitted to effect such
compromise or settlement unless the indemnifying party (A) reimburses the
indemnified party in accordance with the terms of this section for all
reasonable fees and expenses incurred by the indemnified party in connection
with the action, claim or suit, and (B) assumes the defense of the action,
claim or suit.

             (d) LIMITATION ON INDEMNIFICATION. No claim for indemnification

             (e) NO OTHER RIGHTS AND REMEDIES. The indemnification rights under

terminate their employment with the Company. The employment of each officer and
employee of the Company is terminable at the will of the Company. Neither the
Company nor any employee is a party to, or is bound by, any agreement which
would limit in any material respect: (a) any employee's ability to perform his
obligations as a full time employee of the Company; or (b) the Company's or any
employee's ability or authority to engage in any and all lines of business in
which the Company currently engages or proposes to engage as set forth in its
current business plan.

         3.11 PATENTS AND TRADEMARKS. The Schedule of Exceptions contains a

necessary for its business as now conducted and as proposed to be conducted and
has the unrestricted right to use the foregoing without the payment of any
royalty. To the best of the Company's knowledge, all of the existing patents and
trademarks of the company are valid and all of the pending and proposed patent
applications and applications for registration of trademarks of the Company will
result in the valid issuance of patents or registration of trademarks. The
Company has not received any communications alleging that the Company has
violated or, by conducting its business as proposed, would violate any of the
patents, trademarks, service marks, trade names, copyrights or trade secrets or
other proprietary rights of any other person or entity. Neither the execution
nor delivery of this Agreement or the Agreements, nor the carrying on of the
Company's business as currently


                                       5.
<PAGE>   9


proposed to be conducted, will, to the best of the Company's knowledge, conflict
with or result in a breach of the terms, conditions or provisions of, constitute
a default under, any contract, covenant or instrument under which the Company is
bound. To the best of the Company's knowledge, no employee of the Company is in
violation of any terms of any employee contract, patent disclosure agreement or
any other contract or agreement relating to the relationship of such employee
with the Company because of the nature of the business conducted or to be
conducted by the Company.

         3.12 TRANSACTIONS WITH STOCKHOLDERS, ETC. No stockholder, employee,
officer or director of the Company or member of his or her immediate family, is
indebted to the Company, nor is the Company indebted (or committed to make loans
or extend or guarantee credit) to any of them. To the best of the Company's
knowledge, no employee, officer or director has any direct or indirect ownership
interest in any firm or corporation with which the Company is affiliated or with
which the Company has a business relationship, or any firm or corporation that
competes with the Company, except that employees, officers or directors of the
Company and members of their immediate families may own less than five percent
(5%) of the stock in publicly traded companies that may compete with the
company. No member of the immediate family of any officer or director of the
Company is directly or indirectly interested in any material contract with the
Company.

         3.13 REGISTRATION RIGHTS. The Company is not under any contractual
obligation to register any of its presently outstanding securities or any of its
securities which may hereafter be issued under any securities laws of any
jurisdiction except as set forth in the Investors' Rights Agreement.

         3.14 COMPLIANCE WITH LAWS. The Company has at all times conducted and
is now conducting its business in compliance with all laws, rules and
regulations applicable to it. The Company has all franchises, permits, licenses
and any similar authority necessary for the conduct of its business as now being
conducted by it, the lack of which could materially and adversely affect the
business, properties, prospects or financial condition of the company and
believes it can obtain, without undue burden or expense, any similar authority
for the conduct of its business as planned to be conducted. The Company is not
in default in any material respect under any of such franchises, permits,
licenses or similar authority.

With respect to the property and assets it leases, the Company is in compliance
with such leases, and, to the best of its knowledge, holds a valid leasehold
interest free of any liens, claims or encumbrances.

or indirectly, any liability for brokerage or finders' fees, agents' commissions
or other similar charges in connection with this Agreement or any of the

Purchaser contain a complete summary of all meetings of directors and
stockholders since the time of incorporation and reflect all transactions
referred to in such minutes accurately in all material respects.

         3.22 DISCLOSURE. No representation, warranty or statement by the
Company in this Agreement, or in any written statement or certificate furnished
to the Purchaser pursuant to this Agreement or the transactions contemplated
hereby, contains any untrue statement of a material fact or, when taken
together, omit to state a material fact necessary to make the statements made
therein, in light of the circumstances under which they were made, not
misleading. However, as to any projections furnished to the Purchaser, such
projections were prepared in good faith by the Company, but the Company makes no
representation or warranty that it will be able to achieve such projections.

SECTION 4.   REPRESENTATIONS AND WARRANTIES OF THE PURCHASER.

         Purchaser hereby represents and warrants to the Company as follows:

         4.1 AUTHORIZATION. The Agreements constitute and will constitute valid
and legally binding obligations of the Purchaser, enforceable in accordance with
their respective terms except (i) as limited by applicable bankruptcy,
insolvency, reorganization, moratorium and other laws of general application
affecting enforcement of creditors' rights generally, (ii) as limited by laws
relating to the availability of specific performance, injunctive relief or other
equitable remedies, (iii) to the extent the indemnification provisions of
Section 2.9 of the Investors' Rights Agreement may be limited by applicable
federal or state securities laws and (iv) except to the extent that the amount
of attorneys' fees recoverable in any lawsuit is subject to the supervisory
powers and discretion of the court.

         4.2 PURCHASE ENTIRELY FOR OWN ACCOUNT. This Agreement is made with
Purchaser in reliance upon Purchaser's representation to the Company, which by
Purchaser's execution of this Agreement Purchaser hereby confirms, that the
Shares to be received by Purchaser and the Conversion Shares will be acquired
for investment for Purchaser's own account, not as a nominee or agent, and not
with a view to the resale or distribution of any part thereof, and Purchaser has
no present intention of selling, granting any participation in, or otherwise
distributing the same. By executing this Agreement, Purchaser further represents
that Purchaser does not have any contract, undertaking, agreement or arrangement
with any person to sell, transfer or grant participations to such person or to
any third person, with respect to any of the Shares or Conversion Shares.
Purchaser represents that it has full power and authority to enter into this
Agreement.

         4.3 INVESTMENT EXPERIENCE. Purchaser is an investor in securities of
companies in the development stage and acknowledges that it is able to fend for

the Conversion Shares are characterized as "restricted securities" under the
federal securities laws inasmuch as they are being acquired from the Company in
a transaction not involving a public offering and that under such laws and
applicable regulations such securities may be resold without registration under
the Act only in certain limited circumstances. In this connection, Purchaser
represents that it is familiar with Rule 144 of the Act, as presently in effect,
and understands the resale limitations imposed thereby and by the Act.

         4.6 FURTHER LIMITATIONS ON DISPOSITION. Purchaser acknowledges that the
Shares and, if issued, the Conversion Shares, are subject to restrictions on
transfer as set forth in the Investor Rights Agreement.

grants the Purchaser the right of first refusal to acquire the Company according
to the following terms:


                                      12.
<PAGE>   16


                  (a) The Company shall notify Purchaser in writing in the event
that either (i) the Board of Directors of the Company determines that it is in
the best interests of the stockholders to sell the Company and elects to
actively shop the Company (the "Shop"), (ii) the Company has received a bona
fide offer to purchase the Company (the "Bona Fide Offer), or (iii) the Board of
Directors of the Company determines that it is in the best interests of the
Company to undertake an underwritten public offering and the Company has
received written notice of the approval of such an offering by the commitment
committee (or similar body) of the lead managing underwriter (the "Underwriter")
(the "IPO"); provided, however, that such IPO shall be firmly underwritten and
such Underwriter shall be an underwriter of recognized national standing. In the
case of the Shop, such notification shall include all terms and conditions on
which the Company desires to sell the Company. In the case of the receipt of a
Bona Fide Offer, such notification shall include all terms and conditions of the
offer (including the identity of the offering party, the total consideration
offered and the method of paying the consideration). In the case of the IPO,
such notification shall include the valuation proposed by the Underwriter. This
Section 6.2 is intended to apply to a sale or purchase of the Company regardless
of its form, including a sale or other disposition of substantially all of the
assets of the Company or a merger, consolidation or reorganization.

                  (b) Within thirty (30) days of receipt of such notice with
respect to a Shop or a Bona Fide Offer, Purchaser will have the right to acquire
the Company on the same terms and conditions as are set forth in the above
notice. Within twenty (20) days of receipt of such notice with respect to an
IPO, Purchaser will have the right to acquire the Company at the valuation
proposed by the Underwriter. The thirty (30) and twenty (20) day periods are
referred to collectively herein as the "Option Periods" and individually as an
"Option Period").

                  (c) In the event Purchaser elects not to acquire the Company
within such Option Period, then the Company may, within a ninety (90) day period
following expiration of an Option Period, (i) seek a purchaser for the Company
on the terms set forth in the Shop notice, (ii) accept the Bona Fide Offer;
provided, that such sale or merger may be on terms no more favorable to the
acquiror than those stated in the Bona Fide Offer and notice, or (iii) complete
the IPO. In the case of subsection 6.2(c)(i) above, if the Company identifies a
purchaser for the Company, then the Company shall provide Purchaser with notice
pursuant to subsection 6.2(a)(ii) above and Purchaser shall have the right of
first refusal with respect to such sale as set forth in this Section 6.2. If
such sale or merger or IPO is not completed in such ninety (90) day period, the
procedures set forth in this Section 6.2 must be complied with again.

         6.3 NEGATIVE COVENANTS. So long as Purchaser owns at least 250,000
shares of Series B Stock, the Company may not without the approval of the
representative of the Series B Stock on the Company's Board of Directors:

                  (a) issue any debt security in a single transaction or a
series of related transactions with an aggregate principal amount in excess of
fifty percent (50%) of the Company's equity at the closing of such financing;

                  (b) acquire or obtain a ten percent (10%) or greater interest
in, or permit any subsidiary of the Company to acquire or obtain a ten percent
(10%) or greater interest in, any stock or other securities of any other
corporation, partnership or entity;

                  (c) declare or pay any dividends on any shares of Common Stock
other than in compliance with Article IV (D)(1) of the Restated Certificate;
provided, however, that repurchase of such shares may be made in connection with
any Restricted Stock Purchase Agreement between the Company and any employee; or

                  (d) sell any Shares which Purchaser does not purchase pursuant
to the Purchaser Option set forth in Section 2.3 above to any third party.

SECTION 7.        MISCELLANEOUS.

         7.1 PRESS RELEASES. Except as otherwise required by law, on or prior to
the Closing Date, Purchaser, on the one hand and the Company, on the other, may

exercise any right, power or remedy accruing to any party, upon any breach,
default or noncompliance by another party under this Agreement, the Agreements

shall it be construed to be a waiver of any such breach, default or
noncompliance, or any acquiescence therein, or of or in any similar breach,
default or noncompliance thereafter occurring. It is further agreed that any
waiver, permit, consent or approval of any kind or character on the Purchaser's

         NOW, THEREFORE, in consideration of the mutual covenants contained

making, as of the Second Closing, all representations and warranties therein,

         2.3 The Company hereby represents and warrants to the Purchasers that
the representations and warranties of the Company made in Section 3 of the
Purchase Agreement are true and correct in all material respects as of the date
of the Second Closing except (i) as set forth on the updated Schedule of
Exceptions delivered to the Purchasers, (ii) the references in such
representations to the audited financial statements of the Company for the year
ended December 31, 1996, and the unaudited balance sheet and income statement
for the quarter ended June 30, 1997 and the months ended July 31, 1997 and
August 31, 1997, and as to changes since August 31, 1997 shall be deemed to
refer to the unaudited financial statements of the Company as of December 31,

Incorporation" of the Company shall be deemed to refer to the Restated
Certificate of Incorporation, as amended by the Certificate of Amendment
attached hereto as Exhibit C (the "Certificate of Amendment").

         2.4 Each Purchaser hereby severally represents and warrants to the
Company as follows:



                                       2.
<PAGE>   24

                  (a) AUTHORIZATION. The Agreement and the Investor Rights
Agreement constitute and will constitute valid and legally binding obligations
of the Purchaser, enforceable in accordance with their respective terms except
(i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium
and other laws of general application affecting enforcement of creditors' rights
generally, (ii) as limited by laws relating to the availability of specific
performance, injunctive relief or other equitable remedies, (iii) to the extent
the indemnification provisions of Section 2.9 of the Investor Rights Agreement
may be limited by applicable federal or state securities laws and (iv) except to
the extent that the amount of attorneys' fees recoverable in any lawsuit is
subject to the supervisory powers and discretion of the court.

                  (b) PURCHASE ENTIRELY FOR OWN ACCOUNT. This Agreement is made
with Purchaser in reliance upon Purchaser's representation to the Company, which
by Purchaser's execution of this First Amendment Purchaser hereby confirms, that
the Shares to be received by Purchaser and the Conversion Shares will be
acquired for investment for Purchaser's own account, not as a nominee or agent,
and not with a view to the resale or distribution of any part thereof, and
Purchaser has no present intention of selling, granting any participation in, or
otherwise distributing the same. By executing this First Amendment, Purchaser
further represents that Purchaser does not have any contract, undertaking,
agreement or arrangement with any person to sell, transfer or grant
participations to such person or to any third person, with respect to any of the
Shares or Conversion Shares. Purchaser represents that it has full power and
authority to enter into this Agreement.

capable of evaluating the merits and risks of the investment in the Company.

                  (d) RESTRICTED SECURITIES. Purchaser understands that the
Shares and the Conversion Shares are characterized as "restricted securities"
under the federal securities laws inasmuch as they are being acquired from the
Company in a transaction not involving a public offering and that under such
laws and applicable regulations such securities may be resold without
registration under the Act only in certain limited circumstances. In this
connection, Purchaser represents that it is familiar with Rule 144 of the Act,
as presently in effect, and understands the resale limitations imposed thereby
and by the Act.

                  (e) FURTHER LIMITATIONS ON DISPOSITION. Purchaser acknowledges
that the Shares and, if issued, the Conversion Shares, are subject to
restrictions on transfer as set forth in the Investor Rights Agreement.

3. CONDITIONS TO ADDITIONAL OBLIGATIONS AT THE SECOND CLOSING. In lieu of the
conditions of each Purchaser's obligations at the Second Closing set forth in
Section 5 of the Purchase Agreement, each Purchaser's obligations to purchase

instrumentality. There is no action, suit or proceeding by the Company currently
pending or which the Company presently intends to initiate.

         3.9 NO DEFAULT. The Company is not in violation or default under any
provision of its Restated Certificate or its Bylaws, each as in effect at the
Closing. The Company is not in violation or default of any provision of any
instrument, mortgage, deed of trust, loan, contract, commitment, judgment,
decree, order or obligation to which it is a party or by which it or any of its
properties or assets are bound which would materially adversely affect the
condition (financial or otherwise), business, property, assets or liabilities of
the Company, or any material note, indenture, mortgage, lease, agreement,
contract, purchase order or other material obligation. There exists no
condition, event or act which after notice, lapse of time, or both, is
reasonably likely to constitute a material default by the Company under any of
the foregoing.

         3.10 EMPLOYEES. The Company does not employ anyone to perform services
for the Company except in the capacity of an employee or consultant. Each
employee of and consultant to the Company has executed a Proprietary Information

agreement. There is no pending or, to the best of the Company's knowledge,
threatened labor dispute involving the Company and any group of its employees.
The Company is not aware that any officer or key employee, or that any group of
key employees, intends to terminate their employment with the Company. The
employment of each officer and employee of the Company is terminable at the will
of the Company. The Company has not received any notice from any third party
alleging that any employee of, or consultant to, the Company is in violation of
any term of any employment agreement or other agreement relating to the right of
such person to be employed by, or to contract with, the Company. Neither the
Company nor any employee is a party to, or is bound by, any agreement which
would limit in any material respect: (a) any employee's ability to perform his
obligations as a full time employee of the Company; or (b) the Company's or any
employee's ability or authority to engage in any and all lines of business in
which the Company currently engages or proposes to engage as set forth in its
current business plan.

royalty. To the best of the Company's knowledge, all of the existing patents and
trademarks of the Company are valid and all of the pending and proposed patent
applications and applications for registration of trademarks of the Company will
result in the valid issuance of patents or registration of trademarks. The
Company has not received any communications alleging that the Company has
violated or, by conducting its business as proposed, would violate any of the
patents, trademarks, service marks, trade names, copyrights or trade secrets or
other proprietary rights of any other person or entity. Neither the execution
nor delivery of this Agreement or the Related Agreements, nor the carrying on of
the Company's business as currently proposed to be conducted, will, to the best
of the Company's knowledge, conflict with or result in a material breach of the
terms, conditions or provisions of, constitute a material default under, any
material contract, covenant or instrument under which the Company is bound. To
the best of the Company's knowledge, no employee of the Company is in violation
of any terms of any employee contract, patent disclosure agreement or any other
contract or agreement relating to the relationship of such employee with the
Company because of the nature of the business conducted or to be conducted by
the Company.

         3.12 TRANSACTIONS WITH STOCKHOLDERS, ETC. No stockholder, employee,
officer or director of the Company or member of his or her immediate family, is
indebted to the Company, nor is the Company indebted (or committed to make loans
or extend or guarantee credit) to any of them. To the best of the Company's
knowledge, no employee or officer, or director who is an employee, of the
Company has any direct or indirect ownership interest in any firm or corporation
with which the Company is affiliated or with which the Company has a business
relationship, or any firm or corporation that competes with the Company, except
that employees or officers, or directors who are employees, of the Company and
members of their immediate families may own less than five percent (5%) of the
stock in publicly traded companies that may compete with the Company. No member
of the immediate family of any officer, or of any director who is an employee,
of the Company is directly or indirectly interested in any material contract
with the Company.

         3.13 REGISTRATION RIGHTS. The Company is not under any contractual
obligation to register any of its presently outstanding securities or any of its
securities which may hereafter be issued under any securities laws of any
jurisdiction except as set forth in the Investor Rights Agreement.

         3.14 COMPLIANCE WITH LAWS. The Company has at all times conducted and
is now conducting its business in compliance with all laws, rules and
regulations applicable to it. The Company has all franchises, permits, licenses
and any similar authority necessary for the conduct of its business as now being
conducted by it, the lack of which could materially and adversely affect the
business, properties, prospects or financial condition of the Company and
believes it can obtain, without undue burden or expense, any similar authority
for the conduct of its business as planned to be conducted. The Company is not
in default in any material respect under any of such franchises, permits,
licenses or similar authority.

other laws of general application affecting enforcement of creditors' rights
generally, (ii) as limited by laws relating to the availability of specific
performance, injunctive relief or other equitable remedies, (iii) to the extent

indemnification provisions of Section 2.9 of the Investor Rights Agreement may
be limited by applicable federal or state securities laws and (iv) except to the
extent that the amount of attorneys' fees recoverable in any lawsuit is subject
to the supervisory powers and discretion of the court.

         4.2 CONSENTS. All consents, approvals, orders, authorizations,
registrations, qualifications, designations, declarations or filings with any
governmental or banking authority on the part of Purchaser required in
connection with the consummation of the transactions contemplated in the
Agreement and the Investor Rights Agreement have been or shall have been
obtained prior to and be effective as of the Closing.

         4.3 INVESTMENT REPRESENTATIONS. Purchaser understands that neither the
Shares nor the Conversion Shares have been registered under the Securities Act.
Purchaser also understands that the Shares are being offered and sold pursuant
to an exemption from registration contained in the Securities Act based in part
upon Purchaser's representations contained in this Agreement. Purchaser hereby
represents and warrants as follows:

                  (a) PURCHASER BEARS ECONOMIC RISK. Purchaser has substantial
experience in evaluating and investing in private placement transactions of
securities in companies similar to the Company so that it is capable of
evaluating the merits and risks of its investment in the Company and has the
capacity to protect its own interests. Purchaser must bear the economic risk of
this investment indefinitely unless the Shares (or the Conversion Shares) are
registered pursuant to the Securities Act, or an exemption from registration is
available. Purchaser understands that the Company has no present intention of
registering the Shares, the Conversion Shares or any shares of its Common Stock.
Purchaser also understands that there is no assurance that any exemption from
registration under the Securities Act will be available and that, even if
available, such exemption may not allow Purchaser to transfer all or any portion
of the Shares or the Conversion Shares under the circumstances, in the amounts
or at the times Purchaser might propose.

                  (b) PURCHASER CAN PROTECT ITS INTEREST. Purchaser represents
that by reason of its, or of its management's, business or financial experience,
Purchaser has the capacity to protect its own interests in connection with the
transactions contemplated in this Agreement and the Investor Rights Agreement.
Further, Purchaser is aware of no publication of any advertisement in connection
with the transactions contemplated in the Agreement.

                  (c) ACCREDITED INVESTOR. Purchaser represents that it is an
accredited investor within the meaning of Regulation D under the Securities Act.

                  (d) INVESTMENT. Purchaser is acquiring the Shares (or any of
the Common Stock into which the Shares are convertible) for investment for its
own account and not with a view to, or for resale in connection with, any
distribution thereof, and Purchaser has no present intention of selling or
distributing the Shares (or any of the Common Stock into which the Shares are
convertible). Purchaser understands that the Shares (and the Common Stock into
which the Shares are convertible) to be purchased by it have not been registered
under the Securities Act



                                      10.
<PAGE>   15

which depends upon, among other things, the bona fide nature of the investment
intent as expressed herein.

                  (e) COMPANY INFORMATION. Purchaser has received and read the
Financial Statements and has had an opportunity to discuss the Company's
business, management and financial affairs with directors, officers and
management of the Company and has had the opportunity to review the Company's
operations and facilities. Purchaser has also had the opportunity to ask
questions of and receive answers from, the Company and its management regarding
the terms and conditions of this investment.

                  (f) RESTRICTED SECURITIES. Purchaser acknowledges and agrees
that the Shares and the Conversion Shares must be held indefinitely unless they
are subsequently registered under the Securities Act or an exemption from such
registration is available. Purchaser has been advised or is aware of the
provisions of Rule 144 promulgated under the Securities Act, which permits
limited resale of shares purchased in a private placement subject to the
satisfaction of certain conditions, including, among other things: the
availability of certain current public information about the Company, the resale
occurring not less than one year after a party has purchased and paid for the
security to be sold, the sale being through an unsolicited "broker's
transaction" or in transactions directly with a market maker (as said term is
defined under the Securities Exchange Act of 1934) and the number of shares
being sold during any three-month period not exceeding specified limitations.

         4.4 TRANSFER RESTRICTIONS. Each Purchaser acknowledges and agrees that
the Shares and the Conversion Shares are subject to restrictions on transfer as
set forth in the Investor Rights Agreement.
