                               PROSPECTUS SUMMARY

  This summary highlights selected information about us. It may not contain all
of the information that you find important. You should carefully read this
entire document, including the "Risk Factors" section beginning on page   and
the consolidated financial statements and their related notes beginning on page
F-1. Some technical terms not explained in this summary are more fully
described in "Business--Our Company," and "-- Industry and Market Background."

                                  Our Company

  We are a leading Asia-focused provider of high quality Internet Protocol, or
IP, based communications services. Since we were founded in October 1997, we
believe we have built one of the largest carrier-grade managed IP networks that
is dedicated to IP telephony connecting Asia and the United States. We believe
that our managed IP network provides our customers with the cost savings of a
packet-switched data network and quality comparable to the traditional circuit-
switched telephone network. We intend to continue to rapidly expand our
geographic coverage to build a truly pan-Asian network that is able to meet the
growing communications needs of our customers.

  We develop and market innovative IP-based communications services to three
sets of customers: consumers, carriers, and corporations. We offer reliable,
low-cost, IP-based international long distance services to consumers. Our IP
telephony services enable consumers to place a call or send a fax inexpensively
from any telephone or fax machine to anywhere in the world. We have achieved
significant growth in the use of our network since we began offering this
service. The number of minutes transmitted over our network increased from
approximately 9.7 million for the quarter ended September 30, 1999 to over 18.5
million for the quarter ended December 31, 1999. We believe that this rapid
growth demonstrates a preference in the market for the advantages offered by
our IP-based network.

  In December 1999, to maximize the use of our network and meet market demand,
we began to offer carrier transmission services. These services include
providing high quality, switched and IP-based voice and fax services to
traditional telecommunications providers, other IP-based carriers, and Web-
based voice and data services providers, or eCarriers. As of February 29, 2000,
we had eight carrier agreements with providers such as AT&T Global
Clearinghouse, Capcom International, New World Telephone, and Telia. In
addition, Dialpad.com, one of the largest eCarriers, has signed a memorandum of
understanding with us to purchase wholesale capacity on our managed IP network
to carry its PC-originated traffic. We expect to achieve significant growth in
carrier traffic.

  We believe IP technologies can fully meet the integrated communications
services needs of corporations by providing voice, data, and enhanced services
over one network. In March 2000, we began offering basic IP telephony services
to corporations in Asia through our product, oPhone. We are also developing our
CommPortal product, an integrated Web-based suite of communications services
that includes instant messaging, PC-based text and voice chat, Web
conferencing, and unified messaging. CommPortal, together with oPhone,
represents our full corporate product, Integrated Communications Services. We
believe this product will allow our corporate customers to reduce
communications costs while enhancing productivity.

  Our stockholders include an affiliate of Anderson Information Technology,
Baring Asia Private Equity Fund, New World Cyberbase, and an affiliate of the
Pacific Group. We will continue to leverage our stockholder base to accelerate
deployment of our network, capture new customers, create marketing and cross-
promotional opportunities, and expand into new markets. In addition, we have
entered into a strategic relationship with NetStar, a pan-Asian network
integrator, to accelerate deployment of our solution to corporations in Asia.

                                       1
<PAGE>


  Our goal is to become the leading Asia-focused Internet communications
services provider, or ICSP, for consumers, carriers, and corporations. We
intend to achieve this goal by pursuing the following strategies:

  .  Leverage our first-mover advantage in Asia;
  . Rapidly expand our IP network throughout Asia;
  . Leverage our strategic relationships throughout Asia;
  . Continue to grow our existing consumer and carrier IP telephony
     businesses;
  . Capture pan-Asian corporate customers with integrated communications
     solutions; and
  . Develop and provide a broad offering of enhanced IP communications
     services.

                        Our Principal Executive Offices

  We incorporated in California in October 1997 under the name Pacific Telekey
Network, Inc. In October 1999, we changed our name to oCen Communications, Inc.
In   2000, we reincorporated in Delaware. Our principal executive offices are
located at 4900 Rivergrade Road, C110, Irwindale, CA 91706, and our telephone
number at that location is (626) 338-6611.

                                                        working capital. We may

                                  RISK FACTORS

  You should carefully consider the following risks in addition to other
information in this prospectus before purchasing our common stock. The risks
and uncertainties described below are the ones that we currently deem to be
material and that we believe are specific to our company, our industry, and
this offering. If any of these or other risks actually occur, the trading price
of our common stock could decline, and you may lose all or a part of your
investment.

RISKS RELATED TO OUR BUSINESS

We have a history of losses, and we anticipate our losses will continue.

  We have incurred significant losses since inception, and we expect to
continue to incur significant losses for the foreseeable future. We reported a
net loss of approximately $4.1 million for the year ended September 30, 1999,
and a net loss of $722,114 for the period from our inception to September 30,
1998. As a percentage of revenues, our net loss was 177% for the year ended
September 30, 1999 and 731% for the period from our inception to September 30,
1998. As of December 31, 1999, our accumulated deficit was approximately $9.3
million. Our revenues may not continue to grow or even continue at their
current level. In addition, we expect our operating expenses and capital
expenditures to increase significantly as we develop and expand our business,
especially our offering of corporate integrated communications services. As a
result, we will need to increase our revenues significantly to become
profitable. In order to augment our revenues, we need to attract additional
users to increase the fees we collect for our services. If our revenues do not
grow as much as we expect or if our expenses increase at a greater pace than
our revenues, we may never be profitable, or if we become profitable, we may
not be able to sustain or increase profitability on a quarterly or annual
basis. Furthermore, it is probable that we will have to recognize significant
charges relating to non-cash compensation in connection with options that we
granted as of December 31, 1999. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

We have a limited operating history upon which you can evaluate us.

  We have only a limited operating history upon which you can evaluate our
business and prospects. We commenced operations on October 14, 1997. You should
consider our prospects in light of the risks, expenses, and difficulties we may
encounter as an early-stage company in the new and rapidly evolving market for
IP-based communications services. The risks include our ability to:

  . increase the number of users of our IP telephony services;
  . develop our corporate integrated communications services business;
  . build revenues to cover the increased marketing expenditures we have
    planned;
  . compete effectively;
  . increase awareness of our brand and build user loyalty; and
  . keep pace with developing technology.

  In addition, because we expect an increasing percentage of our revenues to be
derived from our corporate integrated communications services, our past
operating results may not be indicative of our future results.

We may not be able to expand our revenues and achieve profitability.

  Our business strategy is to expand our revenue sources beyond our consumer
calling services to the sale of carrier transmission services and corporate
integrated communications services. This pursuit has required and will continue
to require us to make significant additions to our sales and marketing and
technology teams. The large investment in capital and other resources required
to create these new revenue streams will result in significant losses for the
foreseeable future, and we cannot assure you that we will be able to expand our
revenue sources or that this strategy will be profitable.

                                       5
<PAGE>

  Currently our revenues are generated primarily from the sale of consumer
calling services. These services generated 100% of our total revenues in each
of the period from inception to September 30, 1998, the year ended September
30, 1999, and the three months ended December 31, 1999. January 2000 was the
first month in which we generated any revenues from carrier transmission
services. Our provision of consumer calling services and carrier transmission
services has not been profitable to date.

  In the future, we intend to generate increased revenues from multiple
sources, many of which are unproven, including the commercial sale of corporate
integrated communications services. We expect that our revenues for the
foreseeable future will be dependent on:

  . our continued sale of carrier transmission services;
  . our ability to develop, launch, and rollout corporate integrated
    communications services successfully;
  . user traffic levels;
  . continued rapid growth of the Internet consumer market;
  . continued improvement of the quality of our global network;
  . our ability to counteract the effects of competition, adverse regulatory
    developments, decreasing international long distance rates, and rising
    access and transmission costs on our prices;
  . the acceptance and use of Internet communications; and
  . the expansion of our service offerings.

  We may not be able to sustain our current revenues from the sale of consumer
calling services and carrier transmission services or to generate revenues
successfully from corporate integrated communications services in the future.

We have not yet developed our CommPortal product, and we may not succeed in
being able to develop, launch, and rollout this product.

  We have made the determination that to improve our margins over the long run,
we must capture the corporate market for enhanced IP-based services in Asia and
that to do so we must develop an integrated Web-based suite of communications
services for corporate customers. We are therefore in the process of developing
a product that would offer corporate customers a variety of enhanced IP
services including instant messaging, PC-based voice and text chat, Web
conferencing, and unified messaging.

  We are, however, still in the initial stages of the development of
CommPortal. We must enter into agreements with technology providers to sell or
license the technologies that will comprise CommPortal. We cannot assure you
that we will be able to enter into these agreements on commercially reasonable
terms. In addition, even after we have identified and licensed or acquired the
applications, we will need to combine these applications into one integrated
solution and add security measures, such as firewalls. We cannot assure you
that we will be able to create an integrated and secure solution in time to
rollout CommPortal as planned or that we will ever be able to offer CommPortal.

Potential fluctuations in our quarterly financial results could make it
difficult for investors to predict our future performance.

  Our quarterly operating results may fluctuate significantly in the future as
a result of a variety of factors, many of which are outside our control. The
factors generally within our control include:

  . the resources we employ to attract users to purchase our corporate
    integrated communications services;
  . the amount and timing of expenses we incur to enhance marketing and
    promotion efforts and to expand our infrastructure; and
  . the timing of announcements or introductions of new services by us.

                                       6
<PAGE>

  The factors outside our control include:

  . changes in international or domestic telecommunications rates;
  . the timing of announcements or introductions of new services by our
    competitors;
  . technical difficulties or network interruptions in the Internet or in our
    managed IP network;
  . changes in the regulatory environment; and
  . general economic and competitive conditions specific to our industry.

  We believe that quarter-to-quarter comparisons of our historical operating
results may not be a good indication of our future performance, nor would our
operating results for any particular quarter be indicative of our future
operating results.

We may be unable to manage our expansion and anticipated growth effectively.

  We have grown rapidly and expect to continue to grow at a similar pace. This
growth has placed, and is likely to continue to place, a significant strain on
our managerial, accounting, operational, and financial resources. To manage our
growth, we must continue to implement and improve our operational, accounting,
and financial systems as well as our managerial controls and procedures. We
cannot assure you that we have made adequate allowances for the costs and risks
associated with this expansion, that our systems, procedures, or controls will
be adequate to support our operations, or that our management will be able to
offer and expand our services successfully. We currently rely on a relatively
small core management team. As we grow, we must not only manage demands on this
team but also increase its resources so that it can continue to expand, train,
and manage our employee base and maintain close coordination among our
accounting, finance, marketing, and sales staff. If we are unable to manage our
expanding operations effectively, our revenues may not increase, our cost of
operations may rise, or we may not be profitable.

The loss of one or more of our key customers would cause a significant decrease
in our revenues.

  We have historically derived the majority of our revenues from a small number
of customers, particularly Abest Communications and Abest International, or
collectively referred to as Abest, STE Communications, Goldman Network, and
Star Communications. In the year ended September 30, 1999, Abest accounted for
44% of our revenues, STE Communications accounted for 14% of our revenues, and
Goldman Network accounted for 11% of our revenues. For the three months ended
December 31, 1999, Abest accounted for 23% of our revenues, Goldman Network
accounted for 23% of our revenues, STE Communications accounted for 21% of our
revenues, and Star Communications accounted for 11% of our revenues. None of
our customers is obligated to purchase additional products or services from us.
Accordingly, we cannot be certain that present or future customers will not
terminate or significantly reduce their purchasing arrangements with us. Any
termination or reduction by those customers would seriously harm our business,
financial condition, and results of operations.

We are experiencing difficulties in collecting accounts receivable from one of
our major customers and cannot assess the probability of collecting this
receivable.

  We are experiencing difficulties in collecting our accounts receivable from
Abest. Abest has been one of our most significant customers, accounting for
approximately 38%, 44%, and 23%, of our total revenues for the period from our
inception through September 30, 1998, the year ended September 30, 1999, and
the three months ended December 31, 1999, respectively. As of December 31,
1999, Abest owed us $815,430, most of which was past due. We believe that non-
payment is the result of a lack of liquidity at Abest. In January 2000,
Tianrong Internet Products and Services, or TIPS, acquired the assets of Abest
but did not assume the liabilities of Abest. We cannot assure you that we will
be able to collect this receivable. Accordingly, we have deferred recognition
of the revenue on the outstanding uncollected receivable due from Abest at
December 31, 1999, and we will recognize revenue on the outstanding receivable
balance only when we collect cash from Abest or otherwise assess the
collectibility of the receivable as probable. Deferred revenue related to the
uncollected Abest receivable at December 31, 1999 represented approximately 36%
of our total deferred revenue. Failure to collect this receivable balance will
negatively impact our financial condition and future cash flows.

                                       7
<PAGE>

We may experience difficulties in collecting future accounts receivable from
distributors.

  We primarily sell our calling cards to distributors who resell the cards to
third parties who then sell the calling cards to end users. We extend credit to
those distributors for the outstanding balances they owe us for these cards. We
are obligated to provide services to the end users of the cards regardless of
whether we collect the receivable balances from the distributors. The failure
to collect a significant portion of our accounts receivable from the
distributors will have a material adverse impact on our business, financial
condition, results of operations, and cash flows.

IP-based communications alternatives may not achieve widespread acceptance,
which could cause our business to fail.

  Our ability to sell our services to end users may be inhibited by the
reluctance of some end users to switch from traditional communications carriers
to IP communications carriers and by concerns with the quality of Internet and
IP telephony and the adequacy of security in the exchange of information over
the Internet. End users in markets serviced by recently deregulated
telecommunications providers are not familiar with obtaining services from
competitors of these providers and may be reluctant to use new providers such
as our company. In addition, international and domestic telecommunications
rates are declining, which in turn is reducing the competitive pricing
advantage that IP telephony provides to end users. IP communications may not
prove to be a satisfactory alternative to traditional telephone service for
reasons including:

  . inadequate development of the necessary infrastructure;
  . lack of acceptable security technologies; and
  . lack of timely development and commercialization of performance
    improvements.

  Our ability to generate revenues from corporate integrated communications
services depends on the migration of traditional telephone network traffic to
our IP network. We will need to devote substantial resources to educating end
users about the benefits of IP-based communications solutions in general and
our services in particular, and as a result, we expect to incur significant
expenditures for advertising and marketing activities in 2000. Potential end
users who have already invested substantial resources in traditional telephone
service may be reluctant or slow to adopt a new technology that makes their
existing equipment obsolete. If end users do not accept our corporate
integrated communications services as a means of sending and receiving
communications, we will not be able to increase our number of users or generate
revenues from those services in the future.

  In particular, critical issues such as security, reliability, cost, ease of
deployment, administration, and quality of service may affect the adoption of
IP telephony services as the means to meet business needs in Greater China and
other parts of Asia.

Operating internationally exposes us to additional and unpredictable risks.

  As of December 31, 1999, substantially all of our traffic originated in the
United States and terminated in Asia, generating virtually all of our revenues
during the three months ended December 31, 1999. We intend to continue to enter
additional markets in Asia and to expand our existing operations outside the
United States, specifically in East Asia including Taiwan, Hong Kong, and the
People's Republic of China, or PRC. International operations are subject to
inherent risks, including:

  . political, social, and economic instability;
  . potentially weaker protection of intellectual property rights;
  . unexpected changes in regulatory requirements and tariffs;
  . export restrictions;
  . fluctuations in exchange rates and imposition of exchange controls;
  . varying tax consequences; and
  . uncertain market acceptance and difficulties in marketing efforts because
    of cultural differences.

                                       8
<PAGE>

Volatility in economic, social, and political conditions in Asia may interrupt,
limit, or otherwise adversely affect our operations.

  We expect to derive a substantial portion of our future revenues from Asian
markets. In 1998, many countries in Asia began to experience significant
economic downturns and related difficulties, including:

  . reduced or even negative economic growth rates;
  . substantial currency depreciations;
  . high interest rates;
  . corporate bankruptcies;
  . declines in the market values of shares listed on stock exchanges and
    other assets;
  . reduced foreign investments in Asian countries; and
  . government-imposed austerity measures.

As a result, there was a general decline in business and consumer spending and
a decrease in economic growth as compared to prior years. Although the
economies of Taiwan and Hong Kong have recently shown signs of improvement, the
economic downturn in Asia has not significantly slowed, and future economic
developments in countries throughout Asia could materially adversely affect our
business, financial condition, and results of operations.

  Volatility has historically been caused by:

  . significant governmental influence over many aspects of local economies;
  . political instability;
  . unexpected changes in regulatory requirements;
  . social unrest;
  . imposition of trade barriers; and
  . wage and price controls.

We have no control over these matters. Volatility resulting from these matters
may create uncertainty regarding our operating climate or adversely affect our
customers' operating budgets, which may adversely impact our business.

Political and economic policies of the PRC government could harm our business.

  A substantial majority of our traffic is terminated in the PRC. In the
future, we expect to generate significant revenues from originating traffic in
the PRC. Since the late 1970s, the PRC government has been reforming the PRC
economic system. These reforms have resulted in significant economic growth and
social progress, but this growth has been uneven across geographic and economic
sectors and has recently been slowing. We cannot assure you that this growth
will continue or that any slowdown will not have a negative effect on our
business. The PRC economy is also experiencing deflation, which may continue in
the future. To offer services in the PRC, we must develop and maintain
strategic partnerships with communications providers who are licensed to
operate in the PRC. We may not be able to form or maintain these strategic
relationships in the PRC or to structure our relationships with PRC companies
in the manner most advantageous to us. Changes in political, economic, and
social conditions in the PRC, adjustments in policies of the PRC government, or
changes in laws and regulations could adversely affect our business.

Payment under business arrangements may be subject to currency risk and foreign
exchange control in the PRC.

  We expect to derive a significant portion of our revenues from our business
activities in the PRC. These business activities will be subject to PRC rules
and regulations on currency conversion. Exchange rate fluctuations of the
Renminbi, the currency of Mainland China, may adversely affect our operations.

                                       9
<PAGE>

  The Renminbi fluctuates because of changes in PRC government policies and
international economic and political developments. In early 1994, the Renminbi
experienced a devaluation against most of the major currencies. Since then, the
official exchange rate for the conversion of the Renminbi to U.S. dollars has
started to stabilize. However, we cannot assure you that the Renminbi will not
become volatile or that it will not be devalued by the PRC government.

  Present PRC law imposes no restrictions on settlement of current account
transactions in currencies other than the Renminbi. We cannot assure you that
this will continue. For foreign exchange transactions under capital accounts,
such as capital contributions and purchase of fixed assets, restrictions are
imposed on the receipt and payment of currencies other than the Renminbi and
prior approval from the State Administration of Foreign Exchange is required.
We cannot assure you that our business partners in the PRC will be able to
freely pay us in any currency other than the Renminbi or that if we are paid in
Renminbi, we will be able to remit the Renminbi payments out of the PRC.

If the PRC does not become a member of the World Trade Organization, the PRC
regulatory environment may liberalize more slowly than expected, if at all.

  Although the PRC has entered into agreements with some governments to
gradually open up the telecommunications sector to foreign investment upon its
accession to the World Trade Organization, or WTO, we cannot assure you that
this liberalization will actually take place. In addition, we cannot assure you
that issuance of additional detailed regulations intended to open up the
telecommunications sector to foreign investment will actually allow foreign
ownership in telecommunications-related businesses in the PRC.

There are economic risks associated with doing business in Taiwan.

  A significant portion of our traffic is terminated in Taiwan. In the future,
we expect to generate significant revenues from originating traffic in Taiwan.
The PRC asserts sovereignty over mainland China and Taiwan and does not
recognize the legitimacy of the Taiwan government. Although significant
economic and cultural relations have been established during recent years
between Taiwan and the PRC, the PRC government has indicated that it may use
military force to gain control over Taiwan if Taiwan declares independence or
if any foreign power interferes in Taiwan's affairs. Relations between Taiwan
and the PRC and other factors affecting the political or economic conditions of
Taiwan could affect our business and the market price and liquidity of our
shares.

  Between late 1997 and early 1999, the NT dollar, the currency of Taiwan,
experienced considerable volatility and depreciation as a result of the
economic downturn in Asia. Continued volatility and depreciation of the NT
dollar could harm our business. Taiwan has recently experienced a recession
primarily due to a reduction in exports due to weakened demand for imported
goods in many Asian countries. A continued recession in Taiwan may adversely
affect our business.

There are economic risks associated with doing business in Hong Kong.

  Hong Kong is a Special Administrative Region of the PRC with its own
government and legislature. Hong Kong maintains a high degree of autonomy from
the PRC under the principle of one country, two systems. We cannot assure you
that Hong Kong will continue to maintain autonomy from the PRC.

  The Hong Kong dollar has remained relatively constant due to the U.S. dollar
peg and currency board system that has been in effect in Hong Kong since 1983.
Since mid-1997, interest rates in Hong Kong have risen significantly, real
estate and retail sales have declined, and Hong Kong has slipped into a
recession. In early 1999, Hong Kong suffered deflation, and the Hong Kong
dollar was subject to currency speculation. We cannot assure you that the Hong
Kong economy will not worsen or that the historical currency peg of the Hong
Kong dollar to the U.S. dollar will be maintained. Recession in Hong Kong,
deflation, or the discontinuation of the historical peg could adversely affect
our business.

                                       10

Fluctuations in the values of foreign currencies could have a negative effect
on our profitability.

  In the course of our international operations, we incur expenses in a number
of currencies. In the future, as we expand by providing corporate integrated
communications services, we may also receive revenues in foreign currencies. We
do not currently engage in currency hedging activities to limit the risks of
exchange rate fluctuations. Fluctuations in the value of foreign currencies
could have a negative impact on the profitability of our global operations,
which would harm our business, financial condition, and results of operations.
In addition, fluctuations in the value of the U.S. dollar against foreign
currencies may make our products and services more expensive than local product
offerings.

If we do not develop the oCen brand, we may not be able to secure and maintain
a leading position in our industry.

  To secure a leading position in our industry, we must strengthen the
awareness of the oCen brand. If we fail to create and maintain brand awareness,
it could adversely affect our ability to sell consumer calling services,
carrier transmission services, and corporate integrated communications services
or reduce our attractiveness to potential partners. Brand recognition may
become more important in the future with a growing number of IP communications
providers.

We will need additional capital to finance our operations in the future, and it
may not be available on acceptable terms or at all, which could force us to
limit or cease our operations.

  We intend to continue to enhance and expand our network to maintain our
competitive position and meet the increasing demands for service quality,
capacity, and competitive pricing. The introduction of our new corporate
integrated communications services will require significant marketing and
promotional expenses. If our cash flow from operations is not sufficient to
meet our capital expenditure and working capital requirements, we will need to
raise additional capital. Raising capital may require us to issue additional
equity, which could cause investors to experience dilution. We cannot assure
you that any other source will be willing or able to provide additional capital
on acceptable terms or at all. If we are unable to obtain additional capital,
we may be required to reduce the scope of our business or our anticipated
growth, which would reduce our revenues.

We depend on our suppliers for the continued operation of our business.

  We are dependent upon our suppliers of equipment and software, including
Cisco routers, Clarent gateways and software, Oracle software, and Sun
Microsystems servers to develop and maintain our network and services. If our
suppliers cease to provide us with the equipment and software necessary for the
operation of our network or to maintain our current equipment, we may not be
able to identify alternate sources of supply in a timely fashion. Any
transition to alternate suppliers would be likely to result in delays,
operational problems, or increased expenses and may limit our ability to
provide services to our users or expand our operations.

If our network is unable to accommodate our capacity needs, this may damage our
reputation, which could result in a loss of customers.

  We expect the volume of traffic we carry over our network to increase
significantly as we expand our operations and service offerings. Our network
may not be able to accommodate this additional volume. If the usage of IP
communications services grows, our managed IP network may not be able to
support the demands placed on it by that growth, and its performance or
reliability may then decline. To ensure that we are able to handle additional
traffic, we may have to enter into long-term agreements for leased capacity. To
the extent that we overestimate our capacity needs or the prices for capacity
decrease, we may be obligated to pay for more transmission capacity than we
actually use or to pay higher prices for the capacity we use, resulting in
costs without corresponding revenues. On the other hand, if we underestimate
our capacity needs, we may be

                                       11
<PAGE>

required to obtain additional transmission capacity from more expensive
sources. If we are unable to maintain sufficient capacity to meet the needs of
our users, our reputation could be damaged and we could lose users.

Damage to our systems and network could interrupt service and result in reduced
revenues and harm to our reputation.

  Our business depends on the efficient and uninterrupted operation of our
computer and communications systems as well as those that connect to our
network. We maintain communications systems in Southern California and Taiwan,
which are seismically active regions. In addition, our systems and those that
connect to our network are subject to disruption from other natural disasters,
or other sources of power loss, communications failures, intentional acts of
vandalism, hardware or software malfunctions, network failures, and other
events both within and beyond our control. Any system interruptions that cause
our services to be unavailable, including significant or lengthy telephone
network failures or difficulties for users in communicating through our network
or our website, could damage our reputation and result in a loss of users.

Our computer systems and operations may be vulnerable to security breaches.

  Our operations depend on the integrity and security of our network and
systems and our ability to protect them from unauthorized access,
modifications, or use by third parties. Our computer infrastructure is
potentially vulnerable to computer viruses, break-ins, and similar security
breaches that could cause interruptions, delays, or loss of services to our
users. We believe that the secure transmission of confidential information,
such as credit card numbers, over the Internet is essential in maintaining user
confidence in our services. We rely on licensed encryption and authentication
technology to effect secure transmission of confidential information. It is
possible that advances in computer capabilities, new technologies, or other
developments could result in a compromise or breach of the technology we use to
protect confidential information. A party who is able to circumvent our
security systems could misappropriate proprietary information or cause
interruptions in our operations. Security breaches also could damage our
reputation, result in the expenditure of significant financial and managerial
resources, and expose us to a risk of loss, litigation, or liability.

Third parties may infringe our intellectual property.

  To protect our rights to our intellectual property, we rely on a combination
of trademark and trade secret laws and confidentiality agreements and other
contractual arrangements with our employees, affiliates, strategic partners,
and others. We do not currently own any issued patents. We may be unable to
prevent or detect the unauthorized use of, or to enforce effectively, our
intellectual property rights. In addition, effective trademark, copyright, and
trade secret protection may not be available in every country in which we offer
or intend to offer our services. Although we have taken steps to protect our
intellectual property rights, we cannot assure you that those steps will be
sufficient or effective. Failure to protect our intellectual property
adequately could harm our brand, devalue our proprietary content, and affect
our ability to compete effectively. Further, defending our intellectual
property rights could result in the expenditure of significant financial and
managerial resources.

Our services may infringe the intellectual property of third parties.

  Third parties may assert claims that we have infringed a patent, copyright,
trademark, or other proprietary right belonging to them. We incorporate
licensed third-party technology in some of our services. In these license
agreements, the licensors have agreed to indemnify us with respect to any claim
by a third party that the licensed property infringes any patent or other
proprietary right so long as we have not made changes to the licensed property.
We cannot assure you that these provisions will be adequate to protect us from
infringement claims. If we are found liable for infringement, we may have to
pay damages or royalties to a third party or be unable to offer the portion of
our services that is found to be infringing. Redesigning these services to
avoid the infringement could result in the expenditure of significant financial
and managerial resources. Defending against any infringement claims, even those
that are not meritorious, could result in the expenditure of significant
financial and managerial resources.

Competition for highly skilled personnel is intense and the success of our
business depends on our ability to attract, retain, and manage key personnel.

  Competition for qualified employees and personnel in the communications
services industry is intense, and there are a limited number of people with
knowledge of and experience in this industry, particularly in Asia. As we
continue to grow, we will need to hire additional personnel in all areas. In
particular, we will need to hire additional sales and marketing personnel to
expand sales to corporate customers as we roll out our CommPortal product in
Asia. Our success depends to a significant degree upon our ability to attract
and retain qualified management, technical, and sales and marketing personnel
and upon the continued contributions of our existing management and personnel.
In particular, our success is highly dependent upon the abilities of our senior
management, particularly Steven San Eng, James Courtney, and Alex Liu. The loss
of the services of any one of these individuals could have a material adverse
effect on our business, financial condition, and results of operations. We do
not have employment agreements with any of our executive officers or maintain
key person insurance on them.

Acquisitions may disrupt our business and divert the attention of management.

  Our industry is characterized by growth through acquisitions. Currently, we
do not have any commitments or agreements for acquisitions. To compete
effectively, however, we may engage in acquisitions in the future. To the
extent we complete acquisitions, they could pose risks, including the
following:

  . undue diversion of management's attention;
  . the assimilation of the operations and personnel of the acquired
    companies;
  . the integration of acquired assets with existing assets;
  . potential adverse short-term effects on reported operating results;
  . the amortization of acquired intangible assets; and
  . the loss of key employees.

Our acquisitions may not result in any return, or a sufficient return, on our
investment, and we may lose all, or substantially all, of our investment.

RISKS RELATED TO THE IP COMMUNICATIONS INDUSTRY

Intense competition could reduce our market share and harm our financial
performance.

  Competition in the market for communications services is becoming
increasingly intense and is expected to increase significantly in the future
from a variety of companies both in the Internet and telecommunications
industries including traditional telecommunications carriers, Internet service
providers, or ISPs, and ICSPs. These and other competitors may be able to
bundle services and products that we do not offer with enhanced Internet and IP
communications services, which could place us at a significant disadvantage.
Many of these companies have greater resources and larger subscriber bases than
we have and have been in operation longer.

  We compete in the growing market for competitively priced consumer long
distance services, including calling cards, call-back services, dial-around or
10-10 calling, and collect calling services. We also compete with
telecommunications providers, long distance carriers, and other long distance
resellers and providers of carrier services for our carrier transmission
services.

  If we are unable to provide competitive service offerings, we may lose
existing users and be unable to attract additional users. In addition, many of
our competitors, especially traditional carriers, enjoy economies of scale that
result in a lower cost structure for transmission and related costs, which
causes significant pricing pressures within the industry. This pricing pressure
has begun to negatively impact our gross margin. In addition, many of our IP
telephony competitors use only the Internet, rather than a managed IP network,
to transmit traffic. Operating and capital costs of these providers may be less
than ours, potentially giving them a competitive advantage over us in terms of
pricing.

                                       13
<PAGE>

  The Greater China and Asian IP communications market is intensely competitive
and characterized by an increasing number of entrants because the start-up
costs are low. In addition, the Asian telecommunications industry is relatively
new and subject to continuing definition and as a result, our competitors may
better position themselves to compete in this market as it matures. Recent and
pending deregulation of some of these markets may further encourage new
entrants.

  The Hong Kong telecommunications industry is also highly competitive.
Companies compete in Hong Kong on the basis of price and quality. The
heightened level of competition in Hong Kong may result in a further reduction
in the prices for telecommunications services in the Hong Kong market. If
pricing pressures continue, this situation may have a material adverse effect
on the future growth and profitability of our Hong Kong business. Existing and
future competition may adversely affect our results of operations.

  In addition to these competitive factors, recent and pending deregulation in
some of our markets may encourage new entrants. We cannot assure you that
additional competitors will not enter markets that we plan to serve or that we
will be able to compete effectively.

Decreasing telecommunications rates may diminish or eliminate our competitive
pricing advantage.

  Decreasing telecommunications rates may diminish or eliminate the competitive
pricing advantage of our consumer calling services and carrier transmission
services. International and domestic telecommunications rates have decreased
significantly over the last few years in most of the markets in which we
operate, and we anticipate that rates will continue to decline in all markets.
Users who select our IP telephony services to take advantage of the current
pricing differential between traditional telecommunications rates and our rates
may switch to traditional telecommunications carriers as pricing differentials
diminish or disappear. We will be unable to use pricing differentials to
attract new customers in the future. In addition, our ability to market our
consumer calling services to customers depends upon the existence of spreads
between the rates offered by us and the rates offered by traditional
telecommunications carriers as well as a spread between the retail and
wholesale rates charged by the carriers from which we obtain wholesale service.
Continued rate decreases will require us to lower our rates to remain
competitive and will reduce or possibly eliminate our gross profit from our
consumer calling services. If telecommunications rates continue to decline, we
may lose users of our consumer calling services and may not be able to generate
revenues from our other IP telephony services. Because the margins on our
consumer calling services are continuing to decline, we must develop and
introduce our corporate integrated communications services on a timely basis to
achieve long term profitability.

U.S. government regulation and legal uncertainties relating to IP telephony
could harm our business.

  Changes in the regulatory environment in the United States could have a
material adverse impact on our business. Traditionally, voice communications
services were provided by regulated telecommunications common carriers through
the use of circuit-switched technology. We offer voice communications to the
public for international calls using packet-switched IP telephony technology,
which has, to date, largely avoided the scope of government regulation applied
to traditional telecommunications common carriers. We believe that our IP
telephony services presently satisfy the legal and regulatory definitions of
information services, which are subject to far less government regulation under
U.S. law than telecommunications services. However, the growth of IP telephony
has prompted closer examination in many governmental jurisdictions as to
whether and how IP telephony should be regulated, thus creating uncertainty as
to the present legal status of our services. That status is subject to further
change as a result of future regulatory action, judicial decisions, or
legislation in any of the jurisdictions in which we operate. In particular, the
Federal Communications Commission, or FCC, which regulates interstate and
international communications in the United States, could issue a decision
addressing the regulatory status of IP telephony. Although, to date, it has not
acted to treat IP telephony as a regulated telecommunications service, the FCC
has said that IP telephony appears to have many characteristics of a
telecommunications service. If the FCC ultimately determines that IP telephony
is, or shares many characteristics with, a telecommunications service, the FCC
could regulate IP telephony as a telecommunications service or otherwise
subject IP telephony to increased regulation.

                                       14
<PAGE>

  Much of the impetus for regulatory change could come from established
regulated telecommunications carriers who have sought and may continue to seek
regulatory, legislative, and judicial actions to restrict the ability of
companies such as ours to provide IP telephony services or to increase the
cost, through additional regulatory burdens, of providing those services.
Whatever the impetus, one area of increased regulation could focus on the
distinction between phone-to-phone telephony service over managed IP networks
on the one hand and integrated PC-to-PC and PC-originated voice services over
the Internet on the other hand. Changes in law or regulation could require the
former to be regulated as telecommunications services while leaving the latter
as unregulated information services. Since we offer phone-to-phone IP telephony
service over managed IP networks, that kind of decision could have a material
adverse effect on our business.

  Application of new regulatory restrictions or requirements could materially
increase our costs of doing business in other ways as well or, in some
circumstances, even prevent our provision of certain services. For example, if
our IP telephony services become subject to the international settlement rate
regime or access charges, the material increase in our costs could offset the
competitive advantage we have over traditional international carriers. If other
regulatory changes prevent us from delivering our services under our current
arrangements, we would have to consider alternate arrangements for providing
our services, including changing our service arrangements with partners or
limiting our service offerings. Other changes in law or regulation could
similarly limit our service offerings, raise our costs, restrict our pricing
flexibility, and limit our ability to compete effectively. Regulations and laws
that affect the growth of the Internet could likewise hinder our ability to
provide our services over the Internet.

The telecommunications infrastructure in the PRC is developing and may not be
reliable.

  Access to the Internet is accomplished primarily by means of the government's
backbone of separate national interconnecting networks that connect with the
international gateway to the Internet. This backbone is owned by the PRC
government and is the only channel through which the domestic PRC Internet
networks can connect to the international Internet network. Although private
sector ISPs exist in the PRC, almost all access to the Internet is accomplished
through ChinaNet, the PRC's primary commercial network, which is owned and
operated by the PRC government. Internet users have no means of getting access
to alternative networks and service, on a timely basis or at all, in the event
of any disruption or failure.

  Our business partners in the PRC will continue to depend on the PRC
government to establish and maintain a reliable Internet infrastructure to
reach a broader base of Internet users in the PRC. We cannot assure you that
the Internet infrastructure in Greater China will support the demands
associated with continued growth. If the necessary infrastructure standards or
protocol or complementary products, services, or facilities are not developed,
our business could be materially adversely affected.

The legal framework for telecommunications businesses in the PRC is developing
and may change in ways that would adversely affect our ability to operate and
grow our business in the PRC.

  The legal framework governing the telecommunications industry in the PRC is
not well established and may change. Laws and regulations may be introduced in
the PRC governing various aspects of the industry and the use of the Internet
as a medium for conducting business. We cannot predict the effect of further
developments in the Chinese legal system, particularly with regard to the
Internet, including the promulgation of new laws, changes to existing laws or
their interpretation or enforcement, or the preemption of local regulations by
national laws.

  In particular, the interpretation and enforcement of existing laws and
regulations may change. Existing laws with respect to, for example,
advertising, distribution of news, or publishing could be applied to Internet-
related businesses but are currently not enforced against these businesses. If
the PRC government should at any time construe existing laws against Internet-
related businesses more strictly or enact new laws dealing with Internet-
related businesses, our business could be materially adversely affected.

                                       15
<PAGE>

  The issuance of new regulations from various governmental departments may
result in overlapping mutually contradictory regulations. This situation could
result in uncertainty for business operations of Internet companies in the PRC
and add to the complexity and intrusiveness of the regulatory environment in
which Internet companies operate.

The legal framework with respect to the Internet and telecommunications is
developing in Hong Kong and may evolve in ways adverse to our business.

  In Hong Kong, only a few pieces of legislation are directly applicable to
Internet-related businesses. It is possible that the legislature may introduce
new laws covering issues such as content, copyright, distribution, and quality
of products and services. The enactment of any new laws or regulations may
hinder the growth of our consumer calling and carrier transmission services
businesses or our other prospective business activities. In addition, changes
in Hong Kong's telecommunications policies, including any policy change
regarding competition, could have a material adverse effect on our business.

  The introduction of any new laws and regulations or changes to existing laws
and regulations that restrict our ability to operate or that lead to increased
compliance costs would have a material adverse impact on our business. In
particular, operations set up on the basis of a current understanding of the
legislative regime may, in the event of a misinterpretation of applicable law
or practice, any changes in that law or practice, or a change in its
interpretation or enforcement policy, result in the established operations
being, or being deemed to be, in breach of law or subject to new or additional
requirements. If our operations cannot be modified to conform to the then
applicable law or practice or its interpretation, we may be unable to conduct
this part of our business.

  Our business in Hong Kong is regulated by the Office of the
Telecommunications Authority of Hong Kong, or OFTA. OFTA regulates the
telecommunications industry in Hong Kong and ensures that the widest range of
quality telecommunications services are available at reasonable cost. OFTA has
the authority to license telecommunications services. Any additional
restrictions or conditions that OFTA imposes on our Hong Kong business may
materially adversely affect our results of operations.

  Our wholly owned subsidiary in Hong Kong obtained a Public Non-Exclusive
Telecommunications Service, or PNETS, license dated February 9, 1999. This
license, which was valid for twelve months, has expired. We are currently in
the process of renewing this license. Although we believe that we will be able
to extend this license, we cannot assure you that a renewal will be granted. If
OFTA does renew our license, it will be subject to suspension, revocation, or
withdrawal by OFTA under certain circumstances, including the violation of
telecommunications laws and regulations, and additional penalties may be
imposed. Current OFTA policy encourages fair and effective competition. To
achieve this goal, it has not placed a limit on the number of licenses issued.
Any restrictions imposed on the number of licenses may adversely affect the
renewal of our PNETS license.

If we are unable to keep pace with rapid technological changes in the
communications industry, our revenues will decrease.

  Our industry is subject to rapid technological change and evolving industry
standards. We cannot predict the effect of technological changes on our
business. We expect that new services and technologies will emerge in the
markets in which we compete. These new services and technologies may be
superior to the services and technologies that we use, or these new services
may render our services and technologies obsolete. In addition, widely accepted
standards have not yet developed for the technologies we use.

  To be successful, we must adapt to our rapidly changing markets by
continually improving and expanding the scope of services we offer and by
developing new services and technologies to meet customer needs. Our success
will depend, in part, on our ability to license or acquire leading technologies
to develop our corporate integrated communications services and to respond to
technological advances and emerging industry standards on a cost-effective and
timely basis. We will need to spend significant amounts of capital to enhance
and expand our services to keep pace with changing technologies or our revenues
will decline.

RISKS RELATED TO THIS OFFERING

Stock prices of Internet-related companies have fluctuated widely in recent
months, and the trading price of our common stock is likely to be volatile,
which could result in substantial losses to investors.

  The trading price of our common stock is likely to be volatile and could
fluctuate widely in response to a number of factors, some of which are beyond
our control. For a list of these factors, see "Risk Factors--Potential
fluctuations in our quarterly financial results could make it difficult for
investors to predict our future performance." In particular, following initial
public offerings, the market prices for stocks of Internet and technology-
related companies often reach levels that bear no established relationship to
the operating performance of these companies. The market prices of the
securities of Internet-related and online companies have been especially
volatile. These broad market and industry factors may significantly harm the
market price of our common stock, regardless of our actual or operating
performance.

We may in the future be the target of securities class action litigation, which
could be costly and time-consuming to defend.

  The trading price of our common stock is likely to be highly volatile. In the
past, securities class action litigation has often been brought against a
company following periods of volatility in the market price of its securities.
Securities class action litigation, if initiated against us, could result in
substantial costs and the diversion of our management's attention and
resources.

No prior public market exists for our common stock, and an active trading
market may not develop.

  Prior to this offering, there has been no public market for our common stock.
We cannot be sure that an active trading market for the common stock will
develop or continue as a result of this offering. Through negotiations with the
underwriters, we will determine the public offering price of the shares of our
common stock. This price will not necessarily relate to our book value, assets,
past operating results, financial condition, or other established criteria of
value. As a result, the shares being offered may trade at market prices below
the initial public offering price.

Sales of additional shares of our common stock into the public market may cause
our stock price to fall.

  Sales of substantial amounts of our common stock in the public market after
this offering or the perception that substantial sales could occur may
adversely affect the prevailing market price of our common stock. These sales
also might make it difficult for us to sell equity securities in the future at
a time and price that we deem appropriate. Upon completion of this offering, we
will have    shares of common stock outstanding or      shares of common stock
outstanding if the underwriters exercise their over-allotment option in full.
This amount includes      shares we are selling in this offering, which may be
immediately resold in the public market. The holders of the remaining shares
have "demand" and "piggyback" registration rights, and these shares will become
eligible for resale 180 days following the completion of this offering, subject
to Rule 144 under the Securities Act of 1933, as amended. We, our officers,
directors, and some existing stockholders have agreed that without the prior
written consent of Lehman Brothers, we and they will not, directly or
indirectly, offer, sell, or otherwise dispose of any shares of capital stock or
any securities that may be converted into or exchanged for any shares of
capital stock for a period of 180 days from the date of this prospectus. In
addition, as soon as practicable after the date of this prospectus, we intend
to file a registration statement on Form S-8 with the Securities and Exchange
Commission covering the shares of common stock reserved for issuance under our
1998 and 2000 stock option plans and our 2000 employee stock purchase plan. We
expect the additional registration statement to become effective immediately
upon filing. Sales of a large number of shares could have an adverse effect on
the market price of our common stock.

Provisions of our certificate of incorporation, bylaws, and Delaware law could
make it more difficult for a third party to acquire us, even if doing so would
be beneficial to our stockholders.

  Provisions of our certificate of incorporation and bylaws impose various
procedural and other requirements, including the existence of a classified
board of directors with staggered, three-year terms, that could make it more

                                       17
<PAGE>

difficult for third parties to acquire us or for stockholders to effect certain
corporate actions. Upon consummation of the offering, our certificate of
incorporation will allow our Board of Directors to issue up to      shares of
preferred stock and to fix the rights, privileges, and preferences of these
shares without any further vote or action by the stockholders. The rights of
the holders of our common stock will be subject to, and may be adversely
affected by, the rights of the holders of any preferred stock that we may issue
in the future. While we have no present intention to issue shares of preferred
stock, any issuance could be used to discourage, delay, or make more difficult
a change in control of us. In addition, our certificate of incorporation
imposes restrictions on calling special meetings of stockholders and prohibits
stockholder action by written consent. Our bylaws impose restrictions on
introducing stockholder proposals. Each of these features could also be used to
discourage, delay, or make more difficult a change in control of us. See
"Description of Capital Stock."

Minority stockholders may not be able to elect any of our directors, which
could deter a takeover even if beneficial to our stockholders.

  Following the offering, our existing stockholders will, in the aggregate,
beneficially own   % of our common stock. These stockholders will be able to
exercise control over all matters requiring approval by our stockholders,
including the election of directors and approval of significant corporate
transactions. This concentration of ownership may also have the effect of
delaying or preventing a change in control of our company, which could have a
material adverse effect on our stock price.

You will face immediate and substantial dilution in net tangible book value.

  The initial public offering price of our common stock is expected to exceed
substantially the tangible net book value per share of the common stock
immediately after this offering. As an investor in this offering, you will pay
$  per share, and the net tangible book value per share is expected to be $
immediately after the offering. The net tangible book value per share
represents the amount of our total assets less total liabilities, divided by
the number of shares of common stock outstanding immediately after the
offering. In addition, to the extent that outstanding options to purchase
common stock are exercised, there could be substantial additional dilution.
Furthermore, investors in this offering will contribute approximately  % of our
net tangible assets but will own only approximately  % of the company.

We do not intend to pay cash dividends to our stockholders.

  We have never declared or paid any cash dividends on our capital stock. We
intend to retain any future earnings to finance our operations and to expand
our business and do not expect to pay any cash dividends in the foreseeable
future.

We have broad discretion as to use of proceeds and may not use the proceeds in
ways that enhance our market value or results of operations.

  Our management can spend most of the proceeds from this offering in ways with
which our stockholders may not agree. Our management will have broad discretion
in applying the net proceeds of this offering, and you will not be able, as
part of your investment decision, to assess or direct how we apply the net
proceeds. Furthermore, our stock price could decline if the market does not
view favorably our use of the proceeds from this offering.

                                USE OF PROCEEDS

  Our net proceeds from the sale of the      shares of common stock in the
offering, assuming an initial public offering price of $    per share and after
deducting an assumed underwriting discount and estimated offering expenses, are
estimated to be $    million or $    million if the underwriters' over-
allotment option is exercised in full. We intend to use $    for network
development, marketing activities, and technology acquisition and development.
We expect to use $    for other general corporate purposes, including working
capital. The amounts actually expended for working capital purposes may vary
significantly and will depend on a number of factors, including the amount of
our future revenues and the other factors described under "Risk Factors."
Accordingly, we will retain broad discretion in the allocation of the net
proceeds of this offering. We may also use a portion of the net proceeds to
acquire or invest in complementary businesses or products. We have no current
plans, agreements, or commitments with respect to any acquisition. Pending
these uses, we will invest the net proceeds of this offering in interest-
bearing, investment grade securities.

                                DIVIDEND POLICY

  We expect to retain any earnings to finance the expansion and development of
our business and have no plans to pay cash dividends after the offering for the
foreseeable future. The payment of dividends is within the discretion of our
board of directors and will depend on our earnings, capital requirements, and
operating and financial condition, among other factors.

                                    DILUTION

  Our pro forma net tangible book value as of December 31, 1999 was
approximately $15.9 million, or approximately $1.09 per share, after giving
effect to the following:

  .  1,066,665 shares of our Series D preferred stock issued in January 2000
     for proceeds of approximately $8.0 million;

  .  the assumed issuance of 176,470 shares of common stock related to the
     portion of our convertible notes issued in January 2000 that converts
     into common stock; and

  .  the related estimated impact of the BCF of approximately $8.0 million
     and $2.1 million related to the Series D convertible preferred stock and
     convertible notes, respectively.

  Pro forma net tangible book value per share is equal to total tangible assets
(total assets less intangible assets) less total liabilities, divided by the
pro forma number of shares of common stock then outstanding. As of December 31,
1999, after giving effect to the sale by us of shares in the offering at an
assumed initial public offering price of $    , our pro forma net tangible book
value (after deduction of an assumed underwriting discount and estimated
offering expenses and the application of the net proceeds) would have been
approximately $    million or $    per share. This amount represents an
immediate increase in pro forma 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:

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

  You should read the following discussion in conjunction with our consolidated
financial statements and notes to those statements and the other financial
information appearing elsewhere in this prospectus. In addition to historical
information, the following discussion contains forward-looking statements that
involve risks and uncertainties. Our actual results may differ materially from
those anticipated in these forward-looking statements due to many factors,
including those set forth under "Risk Factors" and elsewhere in this
prospectus.

Background

  We are a leading Asia-focused ICSP, transmitting voice, fax, and data traffic
for consumers, carriers, and corporations. We were incorporated and launched
our services in October 1997 as Pacific Telekey Network. In October 1999, we
changed our name to oCen Communications, Inc. Our aim is to capitalize on the
growth of the Internet as a communications tool by offering IP telephony over
our transpacific managed IP network, which we are expanding throughout Asia.

  Since our inception, our activities have included:

  . developing our business model to market our services to consumers,
    carriers, and corporations;
  . hiring management and key personnel;
  . building our managed IP network;
  . conducting market research and developing a suite of corporate integrated
    communications services for our future CommPortal product;
  . developing relationships with carriers in Asia and globally to expand our
    managed IP network;
  . developing software and operations processes to enable us to route high
    quality voice and fax services over our managed IP network efficiently
    and cost effectively; and
  . establishing strategic relationships with companies such as Anderson
    Group and New World group in Hong Kong, and the Pacific Group and Chung
    Shing group in Taiwan, for regional marketing and distribution.

  Since our inception, we have experienced significant operating losses and
negative cash flows from operations in each quarterly and annual period. As of
December 31, 1999, we had an accumulated deficit of $9.3 million. The profit
potential of our business is unproven, and our limited operating history makes
it difficult to evaluate us and our prospects. We may not achieve
profitability, or if we achieve profitability, we might not sustain
profitability.

Overview

 Revenues

  We currently generate the vast majority of our revenues from the sale of
calling cards to distributors, marketed through both traditional and online
channels. Our distributors buy the calling cards from us at various discounts
to the retail price. Our distributors resell the calling cards to third parties
who in turn sell the cards directly to end users. We recognize calling card
revenues on a per minute basis as end users use the balances in their prepaid
cards by placing calls, provided that we have no significant obligations
remaining and that collection of the related receivable from the distributor is
probable. We have deferred revenues for all unused balances in end users'
accounts and for receivables from distributors when we cannot assess collection
as probable.

  We are experiencing difficulties in collecting our accounts receivable from
Abest. Abest has been one of our most significant customers, accounting for
approximately 38%, 44%, and 23% of our total revenues for the period from our
inception through September 30, 1998, the year ended September 30, 1999, and
the three months ended December 31, 1999, respectively. As of December 31,
1999, Abest owed us $815,430, most of

                                       24
<PAGE>

which was past due. We believe that non-payment is the result of a lack of
liquidity at Abest. In January 2000, TIPS acquired the assets of Abest but did
not assume the liabilities of Abest. TIPS gave Abest shares of TIPS stock in
exchange for the assets it received from Abest, but these shares, which
constitute restricted stock and are traded on the over-the-counter Nasdaq
Bulletin Board, may not be highly liquid. We have instituted various measures
that we expect will facilitate collection of those receivables, including
refusing to sell Abest additional calling cards and retaining counsel. However,
we cannot assure you that we will be able to collect this receivable.
Accordingly, we have deferred recognition of the revenue on the outstanding
uncollected receivable due from Abest at December 31, 1999, and we will
recognize revenue on the outstanding receivable balance only when we collect
cash from Abest or otherwise assess the collectibility of the receivable as
probable. Deferred revenue related to the uncollected Abest receivable at
December 31, 1999 represented approximately 36% of our total deferred revenue.
Failure to collect this receivable balance will negatively impact our financial
condition and future cash flows.

  Because of continuing deregulation and increasing competition for
communications services, the price of long distance service has fallen in
recent years, and we expect this trend to continue. In the past, we have been
able to offset reductions in our gross margin caused by pricing pressures by
obtaining lower average costs per minute through scaling our network, reducing
our variable operating costs, and increasing high-margin traffic on some
routes. We cannot assure you that we will be able to continue to offset
reductions in our gross margin in the future.

  In January 2000, we began generating revenues from the sale of wholesale
minutes to carriers. While most of our revenues have been generated from sales
of consumer calling services through distributors, and more recently, from
sales of carrier transmission services to carriers, we expect to generate
additional revenues from the sale of basic IP telephony and corporate
integrated communications services to corporations. To date, we have derived a
significant portion of our revenues from a small number of distributors. Any
termination or reduction in sales by these distributors could seriously harm
our business.

 Operating Expenses

  Operating expenses consist of cost of revenues, general and administrative
expenses, sales and marketing expenses, product development expenses,
depreciation and amortization, and stock-based compensation.

  Cost of revenues. Cost of revenues consists primarily of the costs of
providing our customers with access to our managed IP network and the costs
associated with the transmission and termination of customer voice and fax
traffic via our network. We divide cost of revenues into the following
categories: access, transmission, and termination.

  . Access costs relate primarily to inbound toll-free number charges for our
    U.S. consumer calling card business. The toll-free number costs are
    charged on a per minute basis and are directly proportional to the volume
    of minutes for this segment.
  . Transmission costs are costs associated with providing connectivity
    between points of presence, or POPs, on our managed IP network. These
    costs consist of public Internet access costs and costs of leased private
    data circuits including terrestrial, undersea, and satellite circuits.
    Transmission costs are proportional to the effective minute capacity of
    the links. Significant economies of scale apply to transmission costs
    because larger capacity circuits will result in much lower costs per
    minute as the volume of minutes over the circuit increases.
  . Termination costs are costs associated with terminating voice and fax
    traffic onto global traditional telephone networks. Termination costs are
    subject to significant economies of scale due to volume based discounts.

  Historically, our cost of revenues has at times been extremely high due to
two factors. First, there have been times when rapidly increasing demand from
our customers has exceeded the capacity of our managed IP network. This demand
has resulted in periodic traffic overflow onto higher cost traditional
telephone networks,

                                       25
<PAGE>

which has increased our effective cost per minute. Second, as we expand our
network through the addition of new IP routes and higher capacity circuits, we
incur additional related costs including lease line costs, testing costs, and
quality assurance. Because lease line costs are fixed, our effective cost per
minute over these new routes remains high until we achieve significant volumes
of traffic. As we continue to grow, we anticipate that from time to time our
operating expenses may increase on a per minute basis. We expect that these
increases will relate to our decision to route additional traffic over the
traditional telephone network or to add to or increase capacity levels of our
network.

  General and administrative. General and administrative expenses consist
primarily of salary, payroll tax, and benefit expenses and related costs for
general corporate functions, including executive management, administration,
facilities, information technology, and human resources. We expect that general
and administrative expenses will increase in the future as we hire additional
personnel and incur additional costs related to the growth of our business and
operations. In addition, we expect to expand our facilities and incur
associated expenses to support our anticipated growth and to incur expenses
associated with being a public company, including costs of increased insurance
and legal and accounting fees.

  Sales and marketing. Sales and marketing expenses consist primarily of
expenses relating to the salaries, payroll taxes, benefits, and commissions
that we pay for sales personnel and expenses associated with the development
and implementation of our promotion and marketing campaigns. We anticipate that
sales and marketing expenses will increase in the future as we expand our
internal sales force, hire additional marketing personnel, and increase
expenditures for promotion and marketing.

  Product development. Product development expenses consist primarily of salary
and related expenses for engineers and information technology personnel,
consulting fees, lab costs, and market research. Our strategy is to select and
deploy best-of-breed IP system components and to integrate them into a single
service offering. The main focus of our development work to date has been
developing technology and processes to integrate and efficiently manage our IP
network infrastructure and to develop corporate integrated communications
services. Specific applications of the technology that we develop include IP
network management, IP and service traffic measurement, system
interoperability, corporate integrated communications services research,
measurement systems, and billing. We believe that continued investment in
product development is critical to the success of our company and therefore
expect this expenditure to increase in the future.

  Depreciation and amortization. Depreciation and amortization primarily relate
to our networking hardware, gateways, and telephony software. We depreciate our
network equipment over its estimated useful life of three to seven years using
the straight-line method. We plan to acquire more hardware and software to
provide additional capacity to handle the expected increase in traffic as our
volume grows.

  Stock-based compensation. In connection with the grant of stock options to
employees, we recorded total deferred stock-based compensation of approximately
$1.8 million through December 31, 1999. This deferred compensation represented
the difference between the deemed fair value of our common stock for accounting
purposes and the exercise price of these options at the date of grant. We are
amortizing these amounts over the vesting periods of the applicable options,
resulting in non-cash expense of approximately $490,000 for the year ended
September 30, 1999. Annual amortization of deferred compensation for options
granted as of September 30, 1999 will be approximately $192,000, $93,000,
$45,000, and $11,000, for the years ending September 30, 2000, 2001, 2002, and
2003, respectively. These charges will be expensed, generally over the next
four years, in connection with the vesting periods of the options granted.

  In January 2000, we issued 1,066,665 shares of Series D convertible preferred
stock for approximately $8.0 million, or $7.50 per share. We expect to incur an
estimated non-cash charge to equity relating to the BCF on the Series D
convertible preferred stock. The BCF charge is calculated using the deemed fair
value of common stock on the date of issuance, subtracting the conversion price
and then multiplying the resulting amount by the 1,066,665 shares of common
stock into which the shares of Series D convertible preferred stock are
convertible. As the value assigned to the BCF is limited to the proceeds from
the Series D convertible

                                       26
<PAGE>

preferred stock, we expect to record an estimated BCF charge of approximately
$8.0 million. This non-cash equity charge will adversely impact our net loss
per share attributable to holders of common stock for the three months ending
March 31, 2000.

 Interest income and interest expense

  Interest income is comprised of income earned on our cash, cash equivalents,
and investments. Interest expense is comprised of interest paid on notes
payable and capital leases under which we have financed hardware components of
our network.

  In January 2000, we issued convertible notes in exchange for $10.0 million.
As defined in the agreement, these notes are convertible into equity securities
upon the occurrence of certain events and mature in January 2005 if not
converted. Thirty percent of the outstanding principal will automatically
convert into equity securities upon the closing of a sale of equity securities
in which we receive gross proceeds of at least $10.0 million, referred to as a
Qualified Financing. We expect this offering of common stock to constitute a
Qualified Financing. The conversion rate will be $17.00 per equity security, or
if the Qualified Financing is an initial public offering, the lesser of $17.00
or the initial public offering price per share. We have determined that the
$3.0 million portion of the convertible notes that are subject to automatic
conversion upon the closing of a Qualified Financing has an associated BCF
because they are convertible at a discount to the estimated deemed fair value
of the common stock at the date of issuance. As the BCF relates to the issuance
of convertible debt, the value assigned to the BCF, which cannot exceed the
related proceeds, will be charged to the consolidated statement of operations
as additional interest expense when a Qualified Financing occurs. At the date
of issuance, the total value assigned to the automatically convertible portion
was estimated to be approximately $2.1 million. This non-cash BCF charge will
adversely impact our net loss per share.

 Regulatory Environment

  We believe that the services we provide over our managed IP network are not
currently actively regulated in the United States. Several efforts have been
made, however, to enact federal legislation that would regulate certain aspects
of our operations. If adopted, this legislation could increase our costs
significantly and could materially adversely affect our business, operating
results, financial condition, and future prospects. See "Risk Factors--U.S.
government regulation and legal uncertainties relating to IP telephony could
harm our business" and "Business--Regulatory Environment."

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

 Revenues

  Revenues for the three months ended December 31, 1999 were approximately $2.0
million compared to approximately $62,000 for the three months ended December
31, 1998, an increase of approximately $1.9 million. This increase in sales was
attributable to growth in the number of our distributors and sales per
distributor and was partially offset by rate declines from the comparable
period. For the three months ended December 31, 1999, four of our customers,
Abest, Goldman Network, STE Communications, and Star Communications accounted
for 23%, 23%, 21%, and 11% of our revenues, respectively.

 Operating expenses

  Cost of revenues. Cost of revenues for the three months ended December 31,
1999 was approximately $3.4 million compared to approximately $226,000 for the
three months ended December 31, 1998, an increase of approximately $3.2
million. This increase was due to increased demand from our customers that
exceeded the capacity of our managed IP network and resulted in traffic
overflow onto the higher cost traditional telephone network. It was also due to
higher costs per minute associated with the expansion of our network through
the addition of new IP routes and higher capacity circuits.

  General and administrative. General and administrative expenses for the three
months ended December 31, 1999 were approximately $1.1 million compared to
approximately $164,000 for the three months ended December 31, 1998, an
increase of approximately $936,000. This increase was due to an increase in
salaries and benefits, recruiting costs, and facilities expenses resulting from
the growth in our business.

  Sales and marketing. Sales and marketing expenses for the three months ended
December 31, 1999 were approximately $336,000 compared to approximately $17,000
for the three months ended December 31, 1998, an increase of approximately
$319,000. This increase was due to the expansion of our sales and marketing
staff and commissions paid on revenues.

  Product development. Product development expenses for the three months ended
December 31, 1999 were approximately $724,000 compared to approximately $25,000
for the three months ended December 31, 1998, an increase of approximately
$699,000. This increase resulted from hiring technical staff, conducting market
research, building our network, and developing routing processes in the United
States and Asia.

                                       28

  Depreciation and amortization. Depreciation and amortization expenses for the
three months ended December 31, 1999 were approximately $436,000 compared to
approximately $11,000 for the three months ended December 31, 1998, an increase
of approximately $425,000. This increase was due to additions of networking and
telephony hardware and software placed in service.

  Stock-based compensation. For the three months ended December 31, 1999, we
recorded approximately $380,000 related to the amortization of deferred
compensation incurred in connection with the grant of stock options compared to
approximately $61,000 for the three months ended December 31, 1998, an increase
of approximately $319,000. The increase was due to additional option grants and
additional amortization on existing option grants.

 Loss from operations

  Loss from operations for the three months ended December 31, 1999 was
approximately $4.4 million compared to approximately $442,000 for the three
months ended December 31, 1998, an increase of approximately $4.0 million. This
increase was due to the increased costs of expanding our commercial operations
and support staff. It is difficult to draw a meaningful comparison between the
two periods because the three months ended December 31, 1998 reflect operations
prior to the network expansion while the three months ended December 31, 1999
represent the establishment and operation of our network. We anticipate that we
will incur additional operating and net losses for the foreseeable future.

 Interest expense, net

  Our interest expense, net for the three months ended December 31, 1999 was
approximately $400 compared to interest income, net of approximately $8,000 for
the three months ended December 31, 1998. The increase in interest expense was
a result of interest on notes payable and capital leases, which was offset by
increased interest income from the investment of proceeds from the sale of our
preferred stock.

 Net loss

  Net loss for the three months ended December 31, 1999 was approximately $4.4
million compared to approximately $434,000 for the three months ended December
31, 1998, an increase of approximately $4.0 million as a result of the factors
described above.

Year Ended September 30, 1999 Compared to Period From Inception to September
30, 1998

 Revenues

  Revenues for the year ended September 30, 1999 were approximately $2.3
million compared to approximately $99,000 for the period from inception to
September 30, 1998, an increase of approximately $2.2 million. This increase
was due to growth in the number of our distributors and sales per distributor,
partially offset by rate declines from the comparable period.

 Operating expenses

  Cost of revenues. Cost of revenues for the year ended September 30, 1999 was
approximately $3.1 million compared to approximately $233,000 for the period
from inception to September 30, 1998, an increase of approximately $2.9
million. This increase was due to increased demand from our customers that
exceeded the capacity of our managed IP network and resulted in traffic
overflow onto the higher cost traditional telephone networks. It was also due
to higher costs per minute associated with the expansion of our network through
the addition of new IP routes and higher capacity circuits.

  General and administrative. General and administrative expenses for the year
ended September 30, 1999 were approximately $1.7 million compared to
approximately $305,000 for the period from inception to September 30, 1998, an
increase of approximately $1.4 million. This increase was due to an increase in
salaries, benefits, recruiting costs, and facilities expenses resulting from
the growth in our business.

  Sales and marketing. Sales and marketing expenses for the year ended
September 30, 1999 were approximately $403,000 compared to approximately
$11,000 for the period from inception to September 30, 1998, an increase of
approximately $392,000. This increase was due to the expansion of our sales and
marketing staff, and increased commissions paid on revenues.

  Product development. Product development expenses for the year ended
September 30, 1999 were approximately $435,000 compared to approximately
$42,000 for the period from inception to September 30, 1998, an increase of
approximately $393,000. This increase resulted from hiring engineers, software
developers and consultants, conducting market research, building our network,
and testing new routing processes.

  Depreciation and amortization. Depreciation and amortization expenses for the
year ended September 30, 1999 were approximately $270,000 compared to
approximately $27,000 for the period from inception to September 30, 1998, an
increase of approximately $243,000. This increase resulted from the usage of
networking and telephony hardware and software placed in service.

  Stock-based compensation. Stock-based compensation expense for the year ended
September 30, 1999 was approximately $490,000 compared to approximately
$199,000 for the period from inception to September 30, 1998, an increase of
approximately $291,000 representing amortization of deferred compensation
incurred in connection with the grant of options at exercise prices less than
the deemed fair value. This increase was due to increased option grants and
additional amortization on existing option grants.

 Loss from operations

  Loss from operations for the year ended September 30, 1999 was approximately
$4.1 million compared to approximately $719,000 for the period from inception
to September 30, 1998, an increase of approximately $3.4 million. The increase
in loss from operations was due to the increased costs of expanding our
commercial operations and support staff. It is difficult to draw a meaningful
comparison between the two periods because the period from inception to
September 30, 1998 reflects operations prior to the network expansion while the
year ended September 30, 1999 represents the establishment and operation of our
network. We anticipate that we will incur additional operating and net losses
for the foreseeable future.

 Interest income, net

  Interest income, net for the year ended September 30, 1999 was approximately
$26,000 compared to interest expense, net of approximately $3,000 for the
period from inception to September 30, 1998. Our interest income, net
principally represents income from our cash and cash equivalents as a result of
increased cash balances raised from our sale of preferred stock.

 Net loss

  Net loss for the year ended September 30, 1999 was approximately $4.1 million
compared to approximately $722,000 for the period from inception to September
30, 1998, an increase of approximately $3.4 million as a result of the factors
described above.

</TABLE>

  We have experienced growth in revenues in each quarter since inception. The
increase in revenues was attributable to growth in the number of our
distributors and sales per distributor, partially offset by rate declines from
the comparable period. We expect this growth to continue as we diversify our
customer base and expand our capacity to handle traffic over our managed IP
network.

  Historically, we have generated all of our revenues through the sale of
consumer calling services. We have only recently begun to generate revenues
from the sale of carrier transmission services. Our strategy is to generate
revenues from the sale of corporate integrated communications services. We
cannot assure you that we will continue to generate any additional revenues
from the sale of minutes to communication carriers or that we will generate any
revenues from sales to corporations.

  The initial establishment of our network and the rapid growth in customer
demand have caused volatility in our quarterly cost of revenues. At times of
peak demand, overflow is directed towards high cost traditional

                                       31

telephone networks. After we incur initial bandwidth costs, our average per
minute costs gradually decline as we increase traffic flow. This trend was
evidenced by the declining cost of revenues as a percentage of revenues for the
three months ended June 30, 1999 and September 30, 1999. Cost of revenues as a
percentage of revenues increased for the three months ended December 31, 1999,
primarily because of the expansion of our network and the deferral of revenue
related to the uncollected receivable from Abest.

Liquidity and Capital Resources

  From our inception through December 31, 1999, we have funded losses and
capital expenditures from cash provided from financing activities of
approximately $10.8 million from the sale of equity securities.

  Net cash used in operating activities was approximately $276,000 for the
period from inception to September 30, 1998, approximately $1.1 million for the
year ended September 30, 1999, and approximately $2.0 million for the three
months ended December 31, 1999. This increase in net cash used in operations
was due to increasing net losses and an increase in accounts receivable, which
were partially offset by increases in accounts payable, accrued expenses, and
deferred revenue.

  Net cash used in investing activities was approximately $128,000 for the
period from inception through September 30, 1998, approximately $3.1 million
for the year ended September 30, 1999, and approximately $3.4 million for the
three months ended December 31, 1999. This increase was due to capital
expenditures for our IP network and switching infrastructure. For the three
months ended December 31, 1999, capital expenditures totaled $3.4 million,
related primarily to our new Los Angeles SuperPOP, one of our three large,
monitored, secure points of presence, including expenditures for construction
and networking infrastructure.

  Net cash provided by financing activities was approximately $430,000 for the
period from inception through September 30, 1998, approximately $8.5 million
for the year ended September 30, 1999, and approximately $3.2 million for the
three months ended December 31, 1999. Cash flows were primarily derived from
proceeds from equity financings completed during those periods. In January
2000, we raised an additional $8.0 million in cash from the sale of preferred
stock and $10.0 million in cash from the sale of convertible notes. The notes
bear interest at 6.0% per year, and at least 30% of the principal amount of the
notes may be convertible into capital stock.

  In November 1999, we executed a $1,000,000 equipment lease line with a
lender. The term of this line is 36 months with payments due on the first day
of each month. The rate is 3.20% of the applicable equipment cost per month. As
of December 31, 1999, we had no borrowings against this line.

  In January 2000, we agreed to a $1,000,000 equipment lease line with a
lender. This line may be utilized through June 2000 and bears interest at the
yield on 36-month U.S. Treasury Notes, as quoted by the bank, plus 300 basis
points.

  As of December 31, 1999, we had approximately $2.0 million in cash and cash
equivalents. Principal uses of cash have been to fund working capital
requirements and capital expenditures. We estimate that we will make at least
$30.0 million of capital expenditures during the year ending September 30,
2000. We expect our capital expenditures for the year ending September 30,
2000, to include expansion and improvement of our existing data centers in the
United States and Asia, development of CommPortal, growth of our customer base
in Asia, and acquisition of network and switching infrastructure.

  Additionally, we will evaluate possible acquisitions of, or investments in,
complementary businesses, technologies, or services and plan to expand our
sales and marketing programs. Any acquisition may be material and may require
us to incur a significant amount of debt or issue a significant number of
equity securities. Furthermore, any businesses that we acquire will likely have
their own capital needs, which may be significant and which we would be called
upon to satisfy independent of the acquisition price.

  Our ability to fund planned capital expenditures will depend on our future
performance, which, to a certain extent, is subject to general economic,
financial, competitive, regulatory, and other factors that are beyond our
control. We believe that the net proceeds from the offering, together with our
operating revenues, will be sufficient to meet our anticipated cash needs for
at least the next 12 months. If we need to raise additional

                                       32
<PAGE>

funds by issuing equity or convertible debt securities, the percentage
ownership of our stockholders will be diluted. Furthermore, any new securities
could have rights, preferences, and privileges senior to those of our common
stock. We currently do not have any commitments for additional financing. We
cannot be certain that additional financing will be available when and to the
extent required or that, if available, it will be available on acceptable
terms. If adequate funds are not available on acceptable terms, we may not be
able to fund our expansion, to develop or enhance our services, or to respond
to competitive pressures.

Segment and Geographic Information

  We operate in one industry segment providing IP-based communications
services. Our business operations are principally based in the United States,
and we had no foreign operations during the period October 14, 1997 (Inception)
though September 30, 1998. For the year ended September 30, 1999 and three
months ended December 31, 1999, all of our revenues were generated within the
United States.

  Long-lived assets by geographical location at September 30, 1999 and December

Year 2000 Compliance

  We have not experienced, and do not expect to experience, any significant
problems associated with year 2000 issues. Similarly, to our knowledge, our
distributors, suppliers, and other third parties with whom we conduct business
have not experienced material year 2000 problems to date. We did not incur
material expenditures to test, repair, or replace equipment.

Qualitative and Quantitative Disclosures About Market Risk

 Foreign currency risk

  We have operations within the United States and Asia. As a result, our
financial results could be affected by factors such as changes in foreign
currency exchange rates or weak economic conditions in the foreign markets in
which we operate. Our operating results are currently exposed and will
increasingly be exposed to changes in exchange rates between the U.S. dollar
and various Asian currencies. We do not currently engage in currency hedging
activities to limit the risks of exchange rate fluctuations.

 Interest rate risk

  We do not hold financial instruments for trading or speculative purposes. Our
financial assets are not subject to significant interest rate risk due to their
short duration. Our only financial liability that bears interest rate risk is
our most recent equipment lease line of credit, which has a stated interest
rate based on that associated with U.S. treasury notes. We do not use any
derivatives or similar instruments to manage our interest rate risk.

Recent Accounting Pronouncements

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

  In April 1998, the AICPA issued SOP No. 98-5, Reporting on the Costs of
Start-Up Activities. SOP No. 98-5 requires that all start-up costs related to
new operations must be expensed as incurred. In addition, start-up costs that
were capitalized in the past must be written off when SOP No. 98-5 is adopted.
The adoption of SOP 98-5 during the third quarter of 1998 did not have a
significant impact on our financial position, results of operations, or cash
flows.

                                    BUSINESS

Our Company

  We are a leading Asia-focused ICSP transmitting voice, fax, and data
communications for consumers, carriers, and corporations. In October 1997, we
founded oCen to capitalize on the opportunity presented by the convergence of
voice and data networks. We believe we have built one of the largest
transpacific, carrier-grade managed IP networks dedicated to IP telephony. Our
managed IP network is a premium data network built with carrier-grade IP
equipment linked by a combination of the public Internet, international leased
lines, and satellite access. We monitor and control our network on a 24x7x365
basis to deliver high quality voice and data services. We believe that our
managed IP network provides our customers with the cost savings associated with
a data network and quality comparable to the traditional telephone network. We
plan to expand our managed IP network throughout Asia to meet the growing
communications needs of our target customers in the region.

  Our services include:

  .  Consumer Calling Services: We market reliable, low-cost international
     long distance telephony services to consumers in the United States and
     Canada through our traditional and online distributors. Our IP telephony
     services enable our customers to place a call or send a fax
     inexpensively from any telephone or fax machine to anywhere in the
     world. Phone-to-phone calls originate and terminate on the public
     telephone network but travel primarily over our managed IP network. Our
     current products include traditional calling cards, virtual calling
     cards, which can be purchased over the Internet, and refill accounts,
     which comprise the long-distance service we provide to our registered
     residential users.

  .  Carrier and eCarrier Transmission Services: We offer competitive, high
     quality, switched and IP voice and fax services to traditional
     telecommunications carriers that have substantial Asia-bound traffic,
     such as New World Telephone, to IP telephony exchanges and
     clearinghouses, such as Asian Capacity Exchange, AT&T Global
     Clearinghouse, and Telia, and to Web-based voice and data service
     providers, or eCarriers, such as Dialpad.com. Since launching our
     carrier transmission services in December 1999, we have signed eight
     carrier agreements and are seeing a steady increase in traffic under
     these agreements.

  .  Corporate Integrated Communications Services: Our goal is to be the
     preferred provider of integrated communications services to corporate
     customers in Asia. We have recently begun to provide oPhone, our voice
     and fax over IP services product, to a select group of corporate
     customers in Taiwan. oPhone offers corporate customers transparent
     direct dial international telephony services at significant savings. Our
     research and development team is also developing CommPortal, an
     integrated Web-based suite of communications services such as instant
     messaging, PC-based text and voice chat, Web conferencing, and unified
     messaging, which together with oPhone, represents our Integrated
     Communications Services product. We expect to introduce CommPortal to
     oPhone customers.

  We have achieved significant growth in the use of our managed IP network
since we began offering services. The number of minutes of traffic over our
managed IP network increased from approximately 9.7 million minutes during the
three months ended September 30, 1999, to over 18.5 million minutes during the
three months ended December 31, 1999. We believe that this growth demonstrates
a preference in the market for the advantages offered by an IP-based network.

  We believe the benefits of IP telephony and the convergence of voice and data
networks cannot be fully realized by ICSPs until they are able to deliver
multiple applications from numerous time zones with different peak access
periods and over various access devices. Those ICSPs who are able to provide
this level of service can enjoy multiple revenue streams, maximize capacity
usage of their network, and reduce unit costs. We have designed our marketing
implementation and product development plan so that we can fully capitalize on
the benefits of IP technologies.

Industry and Market Background

 Voice and data networks are rapidly converging

  Historically, there have been two different kinds of communications
networks--voice and data. Traditional telecommunications service providers have
built voice networks based on circuit-switching technology, which establishes
and maintains a dedicated path for each telephone call until the call is
terminated. Although a circuit-switched system reliably transmits voice
communication, this system is inefficient because it requires use of the
circuit for the entire call, regardless of how much information is transmitted
over the circuit. In most data communications, data does not flow equally in
both directions, and the reserved circuit is therefore underused. Unlike
circuit-switched networks, data networks use IP packet technology, which
divides the traffic carried on the network into packets routed over the
Internet or other IP mediums. Packet technology provides for more efficient use
of network capacity because it does not require a fixed amount of bandwidth to
be reserved for each transmission. Traditionally, packet networks have carried
data traffic, such as email, and circuit-switched networks have carried voice
and fax traffic.

  Traditional telecommunications service providers have avoided the use of
packet technology for transmitting voice calls due to delays and lost packets
that prevent immediate transmission and result in poor sound quality. In 1996,
however, some companies began to develop technologies that allowed voice to be
transmitted over data networks from computer to computer over the public
Internet. These technologies have evolved so that voice and fax can now be
transmitted reliably over data packet networks, without the use of computers,
using a regular telephone or fax machine. As a result of the emerging
opportunities to provide voice over IP and fax over IP inexpensively and
reliably, traditional telecommunications providers and ISPs, as well as
emerging service providers using more recent and improved technologies, are
rapidly building IP networks to provide voice and data services.

 IP has benefits over traditional telephony

  IP packet technology is superior to circuit-switched technology from both a
cost and applications perspective. The cost advantages include the following:

  . Network and capital expenditures. A network based on packet technology
    requires lower capital expenditures and lower ongoing maintenance costs
    because one network can be used for both voice and data and because IP
    equipment generally costs less.
  . Bandwidth. The higher efficiencies of a packet network (8-12 kbps for
    each voice-over-IP call compared to 64 kbps for a circuit-switched call)
    lead to lower bandwidth costs.
  . Settlement charges. An IP network allows providers to bypass the
    international settlement charges that are generally paid by traditional
    telecommunications providers, allowing IP telephony providers to offer
    lower rates for international calls.

  In addition to cost advantages, IP technology enables the provision of
enhanced services such as PC-to-PC and PC-to-phone telephony, instant
messaging, and Web conferencing, as well as traditional data services such as
Internet connectivity and Web hosting. IP networks also provide connectivity to
a greater set of devices than circuit-switched networks. These devices include
digital cellular and other wireless devices, the Web, and computers. With a
richer set of applications and connection devices, IP networks have larger
addressable markets and an increased ability to offer a more complete set of
communications solutions to customers over the same network.

 Customer needs and IP technology are driving the trend towards integrated
communications services

  We believe communications services customers are seeking integrated
communications services, or the ability to source all or most of their
communications services needs from one provider. Today, most consumers

                                       36
<PAGE>

buy voice, data and other communications services from multiple service
providers. We believe that ICSPs, because of cost efficiencies and their
ability to deliver a wide spectrum of communications services over one network,
are best positioned to meet the demands of customers. We believe that
successful service providers are those with IP networks, the ability to develop
or bundle integrated communications services to the end user in a single
network platform, and the ability to provide the end user with a single bill
and source for customer service.

 IP telephony is gaining acceptance by consumers, carriers and corporations

  When IP telephony was first introduced in 1996, calls were transmitted over
the public Internet using first generation technologies. This resulted in poor
or inconsistent quality of service. Nonetheless, due to favorable pricing,
consumers adopted IP telephony, particularly in the form of competitively
priced prepaid calling cards for international long distance. Over the course
of two years, quality of service has improved significantly because of
enhancements made in the next generation of IP hardware and software, the
buildout of managed IP networks, and implementation of quality of service
measures by service providers. Although IP telephony still suffers from
perceptions of poor quality, carriers, both traditional and emerging services
providers, have adopted the service. According to TeleGeography 2000, an
independent market research firm, IP telephony minutes have grown over 300%
from 300 million minutes in 1998 to under 1 billion minutes in 1999. With the
growing use of IP telephony by consumers and carriers, we believe that
corporations will begin to widely adopt IP telephony and enhanced
communications solutions to better meet their business communications needs.

 Global IP telephony and IP communications services revenues expected to grow
rapidly

  International Data Corporation, or IDC, another independent market research
firm, estimated that worldwide IP telephony minutes will grow from
approximately 2.7 billion minutes in 1999 to approximately 135 billion minutes
in 2004, which is equal to an estimated compound annual growth rate of 119%.
IDC further estimated that revenues generated from IP telephony services will
grow from approximately $480 million in 1999 to approximately $19 billion in
2004, which is equal to an estimated compound annual growth rate of
approximately 108%.

 Large potential for IP telephony and IP communications services in Asia

  According to Frost & Sullivan, a third independent market research firm, the
Asia-Pacific region will account for approximately 18% of all global
origination and 22% of all global termination IP telephony minutes between 1996
and 2006. Frost & Sullivan estimated that approximately 211 million IP
telephony minutes and $51 million of IP revenues were generated from the Asia-
Pacific region in 1999. By 2006, these figures are estimated to grow to
approximately 128 billion IP telephony minutes and $19 billion in IP revenues,
which would represent estimated compound growth rates of 150% and 134%,
respectively.

  We believe that the IP telephony and communications market in Asia will grow
faster than in most other parts of the world because of three primary factors.
First, Asia has relatively fewer pre-existing traditional telephone networks
than the United States and Europe. We believe that many new communications
networks in the Asia-Pacific region will be IP networks. Second, in most Asian
markets, traditional telephone networks are more highly regulated than in other
parts of the world, which has led to less competition and higher international
direct dial costs. The cost savings associated with IP telephony, which can
bypass international settlement charges, are therefore even more pronounced.
Third, Asia's growing need for communications services comes at least in part
from the growing population and per capita income that characterize the region.

Our Strategy

  Our goal is to be the leading provider of IP telephony and corporate
integrated communications solutions to customers in Asia. To achieve this goal
we intend to:

 Leverage our first-mover advantage in Asia

  We were one of the first companies to establish an IP network and offer IP
telephony services in Greater China. Since then, we believe we have built one
of the leading brand names in IP communications in Asia. Having an enduring and
leading presence in Asia has allowed us to gain a better understanding of what
our target customer base in Asia demands. Because of our early entrant status,
we have been able to work closely with our target customers and our technology
partners to develop innovative integrated communications solutions for pan-
Asian corporations. We believe that our brand recognition in Asia will
facilitate our efforts to attract carrier customers as well as our efforts to
be the first service provider to deploy a corporate integrated communications
solution on a mass scale.

 Rapidly expand our network throughout Asia

  Our managed IP network contains 19 POPs located in 14 cities in Asia and the
United States. Prior to its deployment, Frost & Sullivan predicted that our
network would be the largest transpacific IP network. Our triangular network of
SuperPOPs in Los Angeles, Hong Kong, and Taipei is capable of supporting up to
50, 30, and 30 million minutes of IP telephony traffic per month, respectively.
We feel that this capacity will be sufficient to meet our needs for the near
term. This network is also highly scalable. We are able to offer services to
our users by providing local access to our network. In addition, through our
POPs and call termination services provided to us by the 21 carriers with which
we interconnect, we are able to cost effectively terminate IP voice and fax
communications in 225 countries. We intend to continue to rapidly add POPs in
additional cities within Asia to provide our customers with additional access
and termination points.

 Leverage our strategic relationships throughout Asia

  We intend to leverage our stockholder base to continue the rapid deployment
of our managed IP network, accelerate the development, launch, and roll-out of
CommPortal, create marketing and cross-promotional opportunities, and enter new
markets. Our strategic investors include an affiliate of Anderson Information
Technology, New World Cyberbase, and Pacific Resource Technology. Anderson
Information Technology, an affiliate of Anderson Group, a privately held
conglomerate with various interests in real estate and technology in Greater
China and the United States, is helping us expand into Greater China. New World
Cyberbase, the Internet arm of the New World group, one of Hong Kong's largest
companies and the largest foreign investor in the PRC, is one of our strategic
partners. We intend to leverage the significant resources of the New World
group, such as its access to engineers in the PRC, to develop our CommPortal
product. In addition, New World Telephone, an affiliate of the New World group,
has signed an agreement with us under which we intend to continue to sell it
significant wholesale minutes. Pacific Resource Technology, a part of the
Pacific Group of Taiwan, is helping us expand throughout Asia.

 Continue to grow our existing consumer and carrier telephony businesses

  The majority of our revenues are currently derived from the sale of
international long distance voice and fax over IP services. We intend to
aggressively grow our existing consumer and carrier telephony businesses, in
part by generating Asia-originated traffic. We intend to expand our voice and
fax over IP services to gain economies of scale that will drive down network
and bandwidth costs. We believe that voice and fax over IP will continue to be
attractive services for us to offer, particularly with scale and Asia-
originated traffic, where the margins are higher than traffic originated from
the United States.

 Capture pan-Asian corporate customers with integrated communications solutions

  We expect to derive significant revenues in the future by providing
integrated communications services to pan-Asian corporations, beginning with
basic voice and fax over IP long distance services via our oPhone

                                       38
<PAGE>

product. To ensure consistent high quality service, our team, in conjunction
with our marketing partners, such as NetStar, will market, deploy, and service
enterprise IP gateways directly on the corporate site to offer transparent
international direct dial services over our managed IP network at significant
savings. This implementation will allow the corporate customer to switch from a
legacy network to our network to achieve quality of service levels and
recognize substantial cost savings with minimal inconvenience to the user. We
recently began trials of oPhone with select corporate customers in Taiwan. We
intend to continue to pursue additional marketing relationships to accelerate
the development, launch, and roll-out of our solution.

 Develop and provide a broad offering of enhanced IP communications services

  Over the last six months, our research and development team has been
developing CommPortal, an integrated Web-based suite of communications
services, such as instant messaging, PC-based text and voice chat, Web
conferencing and unified messaging. We will introduce this service to our
customers later this year as part of our integrated communications services
offering, or Integrated Communications Services, that will help us to gain and
retain corporate customers. Through oPhone and CommPortal, we believe we will
have a unique integrated services offering that will help us to gain and retain
corporate customers and generate diversified, sustainable revenues with higher
margins.

Our Customers and Services

  We develop and market innovative IP-based services to three distinct customer
groups--consumers, carriers, and corporations. We provide all of our services
over a single managed IP network.

 Consumer calling services

  We market international long distance services to consumers in the United
States and Canada through our traditional and online distributors. Our current
products include traditional calling cards, virtual calling cards, and refill
accounts, which are described below:

  . Traditional Calling Cards. We sell traditional prepaid calling cards for
    international long distance, typically in retail denominations of $5,
    $10, and $20 per card. All cards provide global termination services as
    well as domestic U.S. long distance. Where we have a POP, our rates are
    more competitive than those offered by traditional telecommunication
    providers. To use the cards, consumers typically dial a toll-free number
    and then enter the card's PIN to access our network and be billed for the
    service. We market oCen branded and co-branded cards in North America.

  . Virtual Calling Cards. Virtual calling cards are similar to our
    traditional calling cards, without a physical card presented. We
    wholesale these cards and provide PINs to Internet partners and
    distributors or sell directly to the end user via the Internet.

  . Refill Accounts. We have a limited number of residential refill account
    customers who, after registering their home phone numbers with us, can
    access our network for long distance services without entering a PIN.
    These services are on a post-paid basis.

 Carrier and eCarrier transmission services

  We offer competitive high quality switched and IP voice and fax services to
traditional carriers, IP carriers, clearinghouses, and eCarriers.

  . Traditional Carriers. Carrier customers connect to one of our SuperPOPs
    in Los Angeles, Hong Kong, or Taipei to buy and sell wholesale
    international telephony traffic through us. Traditional carriers do not
    need an IP network but can connect their circuit-switched network
    directly to our data center. The open and flexible architecture of our
    data center allows rapid and easy interconnection with all types of
    carriers. Circuit-switched carriers connect to us because we offer high
    quality and competitive international rates for their routes. Some of our
    carrier customers include Hong Kong-based New World Telephone and U.S.-
    based DirectNet Telecommunications.

                                       39
<PAGE>

  . IP Carriers. Other IP-based carriers, particularly those using Clarent
    technology, connect to our managed IP network to buy and sell wholesale
    traffic. These include emerging carriers such as Capcom International in
    Spain, which connects to us to purchase Asia capacity. Traditional
    carriers who are moving to IP telephony, such as SK Telelink, a
    subsidiary of SK Telecom, in South Korea, also connect to us to exchange
    minutes. The opportunity to exchange wholesale traffic with other
    Clarent-based IP carriers is significant, especially in the Asia-Pacific
    region.

  . Clearinghouses and Exchanges. Several IP telephony clearinghouses and
    exchanges have emerged in the last two years to capitalize on the growth
    of the industry. They act as brokers among many different carriers, IP or
    traditional, to exchange traffic. We have negotiated agreements and
    connected our network with Asian Capacity Exchange, Telia, and AT&T
    Global Clearinghouse.

  . eCarriers. eCarriers are Web providers who provide real-time applications
    over the Internet, such as PC or Web-originated voice traffic. Most
    eCarriers offer free or heavily discounted PC-to-PC or PC-to-phone
    services in exchange for revenues from advertisers. Most eCarriers today
    carry their traffic over the public Internet, but some are beginning to
    offer services over managed IP networks, such as ours. Dialpad.com, one
    of the largest eCarriers, has signed a memorandum of understanding with
    us to purchase wholesale capacity on our managed IP network to carry its
    PC originated traffic.

  For all categories of carrier customers, we offer three points of
interconnection--Los Angeles, Hong Kong, or Taipei. U.S.-based carriers can
easily connect to our SuperPOP in Los Angeles, and Asia-based carriers have the
convenience of two separate SuperPOPs in Hong Kong and Taipei. Because we have
one of the largest transpacific managed IP networks and are able to source
highly competitive global rates from the Los Angeles telecommunications hub,
our wholesale rates are generally very competitive. Since starting our carrier
transmission business in December 1999, we have signed eight carrier
agreements.

 Integrated Communications Services

  We have developed a business plan to offer integrated communications services
to pan-Asian firms. Our total service offering includes oPhone, our basic
international IP telephony product, and will include CommPortal, our integrated
enhanced services product. Our target customers include trading firms and
conglomerates, hotels, food distributors, and financial institutions. We intend
to be the first provider in Asia with an enterprise solution for IP-based
integrated communications services. We believe we can succeed because we are
one of a few select companies focusing on the growing Asian corporate market.

  . oPhone. oPhone is our international telephony product for corporations.
    We install IP equipment, such as gateways, at the customer's site and
    connect this equipment to the customer's private branch exchange. Via
    dedicated bandwidth to our local data center, the customer can access our
    managed IP network to enjoy transparent international direct dial
    services at significant savings to traditional service providers. We may
    partially finance the IP hardware, software, and local loop charges,
    depending on the customer's expected traffic volume. We believe oPhone
    will prove especially valuable to enterprises that wish to connect
    multiple offices in Asia but do not have existing data or virtual private
    networks.

  . CommPortal. We expect CommPortal to be a Web-based suite of integrated
    communications services designed to enhance communications and improve
    productivity for corporate users. We further expect oPhone corporate
    customers to be able to choose and customize from a menu of CommPortal
    services they find useful. We will transmit all real-time services over
    our managed IP network to ensure consistent quality of service. We will
    also build in security measures and customize CommPortal for the language
    and usage needs of each corporate customer.

                                       40

 Instant Messaging                 Provides real-time notification of when a
                                   person is online and enables the user to
                                   send text and voice messages immediately.

 PC-originated voice and fax       Enables a user to send or receive phone
                                   calls directly through the user's PC or
                                   browser while remaining online. For example,
                                   a user on the Internet will receive a pop-up
                                   screen stating that someone is calling. The
                                   user can then choose to forward the call to
                                   voicemail or to answer the call from the
                                   computer without logging off the Internet.

 Web conferencing                  Enables a user to set up a conference call
                                   through our interactive
                                   communications portal either by sending a
                                   notice of the planned call to all of the
                                   participants and having each participant
                                   dial a toll-free number or by arranging for
                                   each of the participants to be called by the
                                   automated system at the designated call
                                   time. This service eliminates the need for a
                                   conference operator.

 Unified Messaging/Universal Inbox Enables a user to retrieve all voicemails,
                                   faxes and emails from one convenient
                                   location on a user's desktop or via a Web
                                   browser.

 IP Virtual Private Networks       Provide basic voice and fax over IP services
                                   within an intranet structure for medium and
                                   large multinational corporate customers.

 Collaboration                     Enables multiple users to view and edit the
                                   same document on their computers while
                                   speaking or interacting with each other
                                   through their PCs.

 Information services              Enables a user to have easy access to
                                   communications information, such as phone
                                   and e-mail directory services.

 Internet Access and Web Hosting   Provides standard Internet access to the
                                   Web, similar to that provided by ISPs.

 Video Conferencing                Enables users to have real time video-based
                                   meetings with one or more individuals using
                                   their PCs.

Sales and Customer Service

  We have a dedicated sales force that is supplemented by members of our
executive management team. Our salespeople are based regionally within the
United States, Hong Kong, and Taiwan. Our senior management focuses on
maintaining and cultivating relationships with our customers. We assign our
sales representatives specific accounts based on their level of experience,
location, and the quality of the relationship between the representative and
the customer. Our primary marketing and sales support is centralized and
directed from our headquarters in Irwindale, California. We also have a full-
time staff dedicated to our marketing efforts. The marketing and sales support
staff implement our marketing strategies and programs, developing leads,
producing proposals, and making sales presentations. Currently, our marketing
and sales force consists of 18 people, 10 of whom are dedicated to sales of our
consumer calling services, five of whom are dedicated to sales of our carrier
and eCarrier transmission services, and three of whom are dedicated to sales of
oPhone.

                                       41
<PAGE>

 Consumer calling services

  We market our consumer products via both traditional offline channels and
online Web channels. Our distributors typically purchase a large quantity of
PINs or calling cards from us for resale to the consumer. These distributors
make a commission from each card sold. In exchange, they sell our products,
provide the first level of customer service, and manage customer collections.
Our top distributors for the quarter ended December 31, 1999 were:

  . Abest
  . Goldman Network
  . STE Communications
  . Star Communications

  We are increasing our online marketing via Web-based businesses, such as
AsianConnections.com, Asia-Links, Click2Asia.com, and Sina.com, with whom we
conduct joint marketing and branding campaigns. We supplement our channel sales
with print and online advertising. Currently, our calling card business is
focused on Asian communities and consumers in the United States. To reach these
consumers, we have implemented a well-defined direct marketing strategy, using
local foreign language publications and cultural events. Distribution partners
and end users can access their accounts to check billing status via our
Website.

 Carrier and eCarrier transmission services

  We market to carriers and eCarriers mainly through targeted direct mail and
marketing campaigns, attendance and speaking opportunities at conferences and
tradeshows, and word-of-mouth from vendors such as Clarent. To date, we have
not conducted any advertising for carrier marketing but expect to do so in the
future. Registered carrier customers and partners can check rates and billing
status via our Website.

 Corporate Integrated Communications Services

  We have been developing our Integrated Communications Services product, the
combination of oPhone and CommPortal, closely with Clarent, who will be the
supplier of IP equipment, because Clarent is increasingly interested in
developing the corporate IP telephony market. We have conducted market research
and analysis in connection with our development of CommPortal. In addition, we
have signed a memorandum of understanding to partner with NetStar, a pan-Asian
network integrator that currently employs over 200 information technology
professionals and services over 300 existing corporate customers. Based on a
revenue sharing model, NetStar will serve as our marketing and implementation
arm to attract and service corporate customers of oPhone and, eventually,
CommPortal.

Our Network and Operations

 Network Strategy and Design

  We have designed our managed IP network and operations to fully support the
marketing initiatives and requirements of our consumer, carrier, and corporate
products and services. Our managed IP network is a premium data network built
with carrier-grade IP equipment, linked by a combination of the public
Internet, international leased lines, and satellite access. We monitor and
control our network on a 24x7x365 basis to deliver high quality voice and data
services. We have built our network using components selected from leading
suppliers after conducting extensive analysis to determine the highest
performers in each category, or best-of-breed components, such as Clarent IP
gateways and software, Cisco routers, Oracle software, and Sun servers. In
addition, our network is firewall and security protected and continuously
monitored by our 24x7x365 proprietary quality management system. We have
designed our network to deliver the scalable, reliable, and high quality
services that our consumer, carrier, and corporate customers demand.

                                       42
<PAGE>

  Our network characteristics include the following:

  . Blended Bandwidth. We continue to rapidly deploy our managed IP network,
    which consists primarily of dedicated point-to-point IP bandwidth types,
    such as international private leased lines and satellite capacity. When
    managed capacity is not available and quality is acceptable, we also use
    the public Internet to transmit traffic. In addition, we have agreements
    with international IP carriers and traditional carriers, such as Qwest,
    to give us competitive global routing for overflow traffic and to help us
    reach new markets. Our blended bandwidth strategy helps us to scale
    faster by using a variety of transport mediums, to keep costs low by
    leveraging the most cost-effective bandwidth, and to ensure consistent
    quality of service.

  . Network Components. We deploy best-of-breed IP technologies to build our
    premium data IP network. These components include Clarent IP gateways and
    command centers, Cisco routers and Summa switching platforms, Synapsis
    switch controllers, HP Openview Operations support systems, and Oracle
    databases.

  . Management Systems. We have developed and continue to invest in
    management systems that allow centralized, proactive monitoring and
    control of traffic on our network. We have established a Network
    Operations Center, or NOC, at our Los Angeles data center from which we
    monitor and control our global network on a 24x7x365 basis. The NOC
    monitors all aspects of our network including routes, hardware, software,
    and call quality statistics. We have developed a sophisticated,
    proprietary, Web-based traffic routing and call quality management
    reporting system. In addition, NOC staff are equipped with real time
    tools to monitor critical system performance levels and IP quality
    attributes of our routes. NOC technicians use this information to make
    real time re-routing and maintenance decisions to ensure that quality
    levels are maintained. In addition, we are in the process of updating our
    network management tools based upon the HP Open View system.

  . Firewall and Security. Our approach to network security is to screen and
    control traffic flows on our private IP backbone through the use of a
    firewall system. Our network is protected by perimeter security at all
    points of public interconnection. Individual corporate and production
    servers are locked down according to industry standard security
    checklists. All these measures are to ensure the availability,
    reliability, and integrity of our network.

 Network locations and capacity

  As of February 29, 2000, our network had approximately 2,900 IP ports
deployed in our command center control and 2,400 IP ports in service,
distributed across 14 cities in Asia and the United States. Through our
interconnect agreements with traditional carriers and other IP networks, we are
able to terminate traffic in 225 countries. Our network backbone is anchored by
three SuperPOPs located in Los Angeles, Hong Kong, and Taipei. Each SuperPOP
serves as both a hub to aggregate traffic as well as a transit point for
termination routes. By establishing multiple traffic hubs, we have the
flexibility to choose from multiple bandwidth suppliers, allowing us to
optimize quality and cost savings. Our multiple hub structure also enables us
to direct the routing of traffic more efficiently. In addition, traditional
carriers can connect their circuit-switch networks directly to any of our three
SuperPOPs. We have designed the infrastructure of our SuperPOPs to support up
to 50 million minutes of voice traffic per month in Los Angeles and up to 30
million minutes per month for each of Hong Kong and Taiwan. We believe that
this capacity will be sufficient to meet our needs for the near term. In
addition, we can quickly increase these capacity levels as demand increases by
populating our SuperPOPs with additional equipment and provisioning additional
bandwidth.

Customer Service and Billing

  We have developed customer care and billing capabilities tailored to each of
our customer groups.

  . Consumers and distributors. Our consumer services are supported by our
    online interactive customer care and billing center, which enables a
    distributor or user to monitor and set up an account, receive an account
    number and a PIN, pay by credit card for services and contact our
    customer service

                                       43
<PAGE>

   representatives. Most consumer concerns can be addressed online. In
   addition, customers can use our multilingual toll-free number on a
   24x7x365 basis. Our customer support department responds to user inquiries
   primarily through e-mails typically within 24 hours. We strive to
   continually improve our customer care center to meet the evolving needs of
   our users.

  . Carriers. Our support to carrier customers is similar to the support we
    provide to our distributors with additional support from our NOC. The NOC
    staff is available on a 24x7x365 basis. Our engineering staff also
    directly assists our carrier customers by handling all technical problems
    referred by the NOC. Our carrier services department handles all rate
    administration, billing, account reconciliation, deposits, and credit
    management functions for carrier accounts. In addition to these support
    activities, we provide professional project management support for all
    new provisioning activity associated with these accounts. The project
    management team coordinates and oversees all activities associated with
    new service introduction including engineering, ordering, installation,
    rate and route administration and acceptance testing.

  . Corporations. We have extended the core capabilities of our distributor
    and carrier billing systems to provide support for our corporate
    customers. Web-based access to corporate account information is a
    centerpiece of our approach to the corporate market. We are developing
    and intend to launch a new support function associated with CommPortal
    that includes a customer care and billing requirements definition phase
    that will result in further enhancements to our billing and customer care
    system capabilities.

Competition

  We compete in both the market for consumer calling services and the market
for carrier transmission services. Each of these markets is highly competitive
and has numerous service providers. We intend to enter the market for corporate
integrated communications services, which is currently in its infancy in Asia.

  The market for IP communications services is new and rapidly evolving. We
believe that the primary competitive factors determining success in the IP
communications market are:

  . quality of service;
  . price;
  . the ability to meet and anticipate customer needs;
  . responsive customer care services;
  . breadth of geographic presence; and
  . broad offering of communications services, especially enhanced services.

 Consumer Calling Services

  We compete in the growing market of competitively priced consumer long
distance services, including calling cards, call-back services, dial-around or
10-10 calling, and collect calling services. We compete with IP telephony
providers such as Net2Phone and deltathree.com. In addition, we compete with
traditional telecommunications carriers, including industry leaders such as
AT&T and MCI/WorldCom. These providers are significantly larger than we are,
and many have:

  . substantially greater financial, technical and marketing resources;
  . larger networks;
  . a broader portfolio of services;
  . stronger name recognition and customer loyalty;
  . well-established relationships with many of our target customers; and
  . an existing base of users to whom they can cross-sell their services.

                                       44
<PAGE>

 Carrier Transmission Services

  We compete with telecommunications providers, long distance carriers, and
other long distance resellers and providers of carrier services for our carrier
transmission services. Our primary competitors in providing carrier
transmission services include:

  . long distance carriers, including AT&T and MCI/WorldCom;
  . global telecommunications alliances, including BT/AT&T;
  . emerging carriers providing transmission services over the Internet,
    including AT&T Global Clearinghouse, iBasis, and ITXC; and
  . wholesale carrier providers, including STAR and Pacific Gateway Exchange.

  Competition for carrier traffic is primarily based on price and access to
limited routes and markets. Decreasing telecommunications rates have resulted
in intense price competition, and we expect that competition will continue to
increase significantly as telecommunications rates decrease. Increased
competition could force us to further reduce our prices and may reduce profit
margins and our market share. Our need to stay competitive may require us to
invest in new routes or to pay for access into other key markets, each of which
could impact our margins.

 Corporate Integrated Communications Services

  Future competition could come from a variety of companies in both the
Internet and telecommunications industries, including traditional
telecommunications carriers, ISPs, and ICSPs. These and other competitors may
be able to bundle services and products that we do not offer with enhanced
Internet and IP communications services, which could place us at a significant
disadvantage. Many of these companies have greater resources and larger
subscriber bases than we have and have been in operation longer.

Proprietary Rights

  We rely or expect to be able to rely on trademark and trade secret laws and
confidentiality agreements and other contractual arrangements with our
employees, strategic partners, and others to protect our proprietary rights.

  We have a registered trademark for "oCen." We do not currently own any
registered copyrights or patents.

Regulatory Environment

  The use of the Internet and managed IP networks to provide telephone service
is a recent market development. While we believe that the provision of voice
communications services over the Internet and managed IP networks is currently
permitted under U.S. law, some foreign countries, including Taiwan and the PRC,
have laws or regulations that may restrict or prohibit voice communications
over the Internet.

 The Regulatory Framework in the United States

  In the United States, we operate under a regulatory framework that
distinguishes between "telecommunications services," which are heavily
regulated, and "information services," which are largely unregulated. There is
considerable uncertainty concerning the classification within this framework of
IP telephony in general and phone-to-phone IP telephony in particular. To date,
the FCC has not acted to treat IP telephony as a telecommunications service.
For that and other reasons, we believe that therefore our IP telephony traffic
presently qualifies as an information service. As a result, our international
IP telephony traffic is not subject to access charges or the international
settlement rate regime, which dramatically reduces our cost in providing
international calling services.

                                       45
<PAGE>

  By contrast, the overflow international traffic that we carry overseas using
conventional circuit-switched carriers qualifies as regulated
telecommunications traffic and is therefore subject to access charges or the
international settlement rate regime. Some of our other services are also
governed by the regulations applied to traditional telecommunications service
providers. It is possible for our customers to use our calling cards to place
both intrastate and interstate domestic calls. Those calls, which constitute a
minimal portion of our traffic, are carried through the resold services of
conventional circuit-switched long distance providers and constitute a
regulated telecommunications service offering.

  In addition to the regulatory framework governing the provision of
telecommunications and information services, our services may be subject to the
general regulation of the Internet, including provisions concerning disclosure
of confidential communications, copyright matters, and excise taxes.

 IP Telephony

  Federal Regulation. We believe that, under U.S. law, the IP telephony
services that we provide constitute information services. To the extent that
our IP telephony services are information services, they are not currently
regulated by the FCC. However, we cannot assure you that our IP telephony
services will not be regulated by the FCC in the future. Although it has not
reached any definitive conclusions, the FCC could determine that IP telephony,
or certain categories of IP telephony services, should be classified as
regulated telecommunications common carrier services or otherwise subjected to
increased regulation. On April 10, 1998, the FCC issued a report to Congress
discussing its implementation of universal service provisions contained in the
1996 amendments to the Communications Act of 1934. In the report, the FCC
indicated that it would examine the question of whether some forms of phone-to-
phone IP telephony are information services or telecommunications services. The
FCC explained that it did not have an adequate record as of the date of the
report on which to make a definitive ruling. However, the FCC said that the
incomplete record it did have suggested that some forms of phone-to-phone IP
telephony appear to have the same functionality as non-IP telecommunications
services and lack the characteristics that would render them information
services. The implication of this FCC report is that some forms of IP
telephony, including in particular phone-to-phone IP telephony, should, and in
the near future might be, regulated as telecommunications services or otherwise
regulated more heavily.

  Many of our competitors and other interested parties have taken the position
that IP telephony should be subject to the same regulatory framework as
telecommunications services. For example, in September 1998, two Regional Bell
Operating Companies, or RBOCs, advised IP telephony providers that they would
impose on Internet and IP telephony traffic the same access charges applied to
traditional telecommunications service providers. It is uncertain at this time
whether or when these RBOCs will actually succeed in imposing access charges on
IP telephony traffic. However, one of the RBOCs recently filed a petition with
the FCC seeking approval of the imposition of access charges on phone-to-phone
IP telephony services.

  If the FCC determines that phone-to-phone IP telephony services are subject
to FCC regulation as telecommunications services, the FCC may subject IP
telephony providers to traditional telecommunications common carrier
regulation. Among other things, IP telephony providers could be required to
make universal service contributions and pay access charges. That determination
by the FCC could also result in IP telephony calls becoming subject to the
international settlement rate regime. It is also possible that the FCC could
adopt a regulatory framework for Internet and IP telephony providers that would
differ from traditional common carrier regulation. In either event, our IP
telephony service offerings could be regulated more heavily, which could have a
material adverse effect on our business, financial condition, and results of
operations. For example, if the FCC determines that IP telephony calls are
subject to access charges and/or the international settlement rate regime, we
would lose much of our cost advantage over conventional providers of
international long distance calling services.

  The intense focus on the regulatory status of the Internet and IP telephony
has resulted in efforts to have Congress enact legislation that would either
regulate or exempt from regulation communications services

                                       46
<PAGE>

provided over the Internet. Congressional dissatisfaction with the FCC's
conclusions could result in requirements that the FCC impose greater
regulation, which in turn could materially adversely affect our business,
financial condition, and results of operations.

  State Regulation. State regulatory authorities may also retain jurisdiction
to regulate the provision of intrastate IP telephony services. Several state
regulatory authorities have initiated proceedings to examine the regulation of
such services, and other states could follow.

 Telecommunications Services

  To the extent that we use circuit-switched networks to provide interstate
long-distance services and overflow international traffic, we must comply with
federal telecommunications laws and FCC regulations governing
telecommunications services. We are similarly regulated by state public utility
commissions to the extent we use traditional circuit-switched networks to
provide intrastate long distance services.

  Federal Regulation. The Communications Act of 1934 and FCC regulations govern
the interstate and international long distance telecommunications services we
provide over traditional circuit-switched networks. The FCC has established
different levels of regulation for dominant and non-dominant long distance
carriers. We are a non-dominant carrier under FCC regulation and are less
heavily regulated than dominant carriers. For example, the FCC does not
regulate the rates that we charge for our interstate and international long
distance services.

  The FCC has also decided that non-dominant long distance carriers should not
file tariffs setting forth their rates for interstate services. However, that
ruling has been stayed until the matter is resolved in a pending court case.
Until the stay is lifted, we are required to file tariffs for our interstate
long distance services. If and when the decision not to require the filing of
tariffs becomes effective, we could benefit from a decrease in compliance costs
and the possible elimination of delays in getting new products and services to
market.

  Despite our non-dominant carrier status, we must comply with those sections
of the Communications Act of 1934 that pertain to providing interstate and
international long distance services using circuit-switched technology. We are
subject to the general requirement that the rates, terms, and conditions of our
services be "just and reasonable" and that we refrain from making any "unjust
or unreasonable" discrimination in our rates, terms, and conditions. The FCC
has the authority to enforce our compliance with these requirements.

  State Regulation. We are subject to state laws and the jurisdiction of the
state public utility commissions for the intrastate long distance services we
provide using traditional circuit-switched networks. Although the degree of
regulation varies from state to state, our calling card services are subject to
regulation by the state public utility commissions in virtually all states
because our customers could use our calling cards to make long distance
intrastate calls, which would then be carried over traditional circuit-switched
networks. In most of the states in which we do or intend to do business, we are
required to obtain authorization from the state public utility commission in
order to provide those intrastate long distance services. In addition, in many
states we are required to file and maintain tariffs setting forth the terms,
conditions, and prices for our intrastate long distance service offerings.

  Our Regulatory Status. We are authorized by the FCC to provide resold
international long distance services, and we have tariffs on file with the FCC
under which we may provide interstate and international long distance services.
On the state level, we are not authorized to provide intrastate long distance
services over the traditional telephone networks. We have sought the
authorization to provide intrastate services in the states of California and
New York. As we have not filed the associated requisite tariffs, however, we
may not be authorized to provide intrastate telephony over traditional
telephone networks in these states. Furthermore, because those authorizations
were obtained when we were incorporated in California under the name Pacific
Telekey Network, we must obtain the prior approval of the state public utility
commissions in those states before we can provide intrastate long distance
services as a Delaware corporation or under the name oCen. We are in the
process of securing those necessary approvals.

                                       47
<PAGE>

  We anticipate being authorized to provide intrastate long distance services
over traditional telephone networks under the name oCen in the remaining 48
states by the end of 2000. Although we believe that our intrastate traffic in
states other than New York and California is negligible at present, the calling
cards we have already issued may be used by customers for that purpose and, if
so, the provision of such service would be outside the scope of any
authorization that we have or need. Those operations could be deemed unlawful
and could result in fines, penalties, and other sanctions, including an order
from a state public utility commission to cease operations in the state for
some period of time. If we were ordered to cease operating in a state, it could
have a material adverse effect on our business.

 The Internet

  Congress has recently adopted legislation that regulates certain aspects of
the Internet, including on line content, user privacy, and taxation. For
example, the Internet Tax Freedom Act prohibits certain taxes on Internet uses
through October 21, 2001. We cannot predict whether substantial new taxes will
be imposed on our services after that date. In addition, Congress and other
federal entities are considering other legislative and regulatory proposals
that would further regulate the Internet. Congress is, for example, currently
considering legislation on a wide range of issues including Internet spamming,
database privacy, gambling, pornography and child protection, Internet fraud,
privacy, and digital signatures. Various states have adopted and are
considering Internet related legislation. Increased U.S. regulation of the
Internet may slow its growth, particularly if other governments follow suit,
which may negatively impact the cost of doing business over the Internet and
materially adversely affect our business, financial condition, results of
operations, and future prospects.

 Regulation in the PRC

  The PRC telecommunications industry is still developing. It is regulated by a
series of administrative and departmental regulations. The principal
regulations include the 1993 Notice Regarding the Further Strengthening of the
Management of the Telecommunications Business Market issued by the State
Council, the 1993 Interim Measures for the Examination and Approval and
Administration of Conducting De-regulated Telecommunications Business issued by
the Ministry of Post and Telecommunications, or MPT, and the 1994 MPT Notice
Regarding Joint Investment on an Experimental Basis to Further Accelerate the
Development of Communications. The Ministry of Information Industries, or MII,
which was formerly the MPT, is the national regulatory authority for
telecommunications network operations and service provision in the PRC.

  The PRC government is in the process of drafting a unified telecommunications
law. We do not know when the new law will be enacted. With the recent
restructuring of various communications-related entities into the MII as well
as the PRC's likely accession into the WTO, the promulgation of the
telecommunications law may be further delayed.

 IP Telephony

  The PRC government regulates access to the Internet by imposing strict
licensing requirements and requiring ISPs in the PRC to use the international
inbound and outbound Internet backbones. In 1996, the State Council promulgated
the PRC Provisional Measures on International Link-up of Computer Information
Networks, or the Link-up Measures, and in 1998 it further promulgated the
Implementing Rules for the Link-up Measures, which collectively provided for an
operation licensing system. The MII then issued the 1998 Notice Regarding
Licensing of Business Operations of International Linkups of Computer
Information Networks, or the 1998 Notice, containing further provisions for the
implementation of the licensing system.

  The types of services which can be provided over the Internet are not limited
to data transmission. However, it is unclear which services may be provided in
the PRC. According to Article 9 of the 1998 Notice, only computer information
services may be provided over the Internet in the PRC, and no
telecommunications services such as telephone and fax may be provided over the
Internet. Recently, this complete ban has been

                                       48
<PAGE>

liberalized and certain pilot local telecommunications operators have been
selected to provide IP telephony services. There are indications that if the
trial operation is regarded by the PRC government as successful, more PRC
providers may be allowed to engage in this business. Foreigners remain
prohibited from investing in IP telephony companies in the PRC.

 Restrictions on Foreign Investment

  The PRC government has consistently reiterated that foreign involvement in
the operation of telecommunications networks and ownership of equity in these
networks is prohibited. The 1993 Opinion of the MPT on Further Strengthening
Control of the Telecommunications Services Market says that foreigners are not
allowed to operate or participate in the operation of telecommunications
businesses in the PRC, and at the same time mainland Chinese are not allowed to
attract foreign equity participation in the operation of telecommunications
businesses.

  In June 1995, the State Council promulgated the Interim Provisions on
Guidelines for Foreign Investment and the Foreign Investment Industrial
Guidance Catalogue. The Guidance Catalogue provides that foreign operation and
management of the postal services and telecommunications business are
prohibited. The same prohibition exists in the revised Guidance Catalogue that
went into effect on January 1, 1998. Because PRC officials have interpreted
telecommunications services to include Internet services, foreign involvement
in Internet services is not allowed.

  Some foreign investors attempted to avoid the prohibition by setting up Sino-
foreign joint ventures, which under PRC laws are domestic entities, which then
operate the telecommunications networks of local PRC telecommunications
companies under a servicing agreement. In 1998, the MII declared these
arrangements "improper," and the PRC government has imposed a time limit for
these creatively structured transactions to be terminated.

  It is commonly believed that a genuine sale and purchase of equipment or an
equipment lease followed by a consultancy or technical support agreement will
not be considered to be a violation of the ban on foreign involvement in
network operation, but those transactions will be subject to strict government
scrutiny. Equipment sales, leases, and similar technical agreements are equally
permitted under PRC laws. However, government officials may disagree with this
understanding and take action to eliminate the consultancy or technical support
arrangements on the grounds that foreign investment in telecommunications
operations are not allowed in the PRC.

 The PRC's WTO Bid and Possible Further Deregulation of the Telecommunications
Industry

  The ban on foreign investment stands in contrast to the recent agreement
reached between the United States and the PRC regarding the PRC's accession to
the WTO. Under that agreement, the PRC will allow 49% foreign investment in all
telecommunications services immediately upon its accession to the WTO and 50%
two years subsequent to accession. On the understanding that telecommunications
services are meant to include Internet services, the PRC-United States WTO
agreement should allow for 49% foreign investment in the Internet industry upon
accession and 50% two years later. The State Council is expected to promulgate
new regulations in early 2000 that will provide clarification on the exact
scope of the telecommunications services to be further opened for foreign
investment. Until such new regulations are enacted, we cannot assure you that
foreign control of a PRC ISP or ICSP is permitted.

 Political Control of the Information Industry in the PRC

  Under the Link-up Measures and the State Secret Protection Regulations for
Computer Information Systems on the Internet, the PRC government controls
Internet access and the distribution of news and other information. The
Propaganda Department of the Communist Party is responsible for censoring news
published in the PRC to ensure, supervise and control political correctness.
The MII has published implementing

                                       49
<PAGE>

regulations that subject online information providers to potential liability
for content included on their portals and the actions of subscribers and others
using their systems including liability for violation of PRC laws prohibiting
the distribution of content deemed to be socially destabilizing. Because many
PRC laws, regulations and legal requirements relating to the Internet are
relatively new and untested, their interpretation and the enforcement of what
is deemed to be socially destabilizing by PRC authorities involves significant
uncertainty.

  From time to time, the Ministry of Public Security has stopped the
distribution of information over the Internet that it believed to be socially
destabilizing. The Ministry of Public Security has the authority, in its sole
discretion, to cause any local ISP to block any website maintained outside of
the PRC.

 Regulation in Hong Kong

  Telecommunications activities in Hong Kong are primarily governed by the
Telecommunication Ordinance and the Telephone Ordinance and their subsidiary
legislation. The Telecommunication (Amendment) Bill is now being considered by
the legislature in Hong Kong. The exact amendments to the Telecommunication
Ordinance and the impact of any amendments will only be known after the bill
has been debated and enacted in its final form.

  Under Section 5 of the Telecommunication Ordinance, a public officer is
appointed as the Telecommunications Authority to administer the
Telecommunication Ordinance and the Telephone Ordinance and to regulate all
different forms of telecommunications. The Telecommunication Authority is also
the Director-General of Telecommunications in Hong Kong. The Telecommunication
Authority's principal responsibilities include the licensing of
telecommunications activities, the promotion of an open and competitive
telecommunications market, the protection of consumer interests, the economic
and technical regulation of the telecommunications industry and the enforcement
of license conditions.

  Since the end of Hong Kong Telecom's exclusive license on local fixed
telecommunications network services in 1995, the deregulation of the domestic
telecommunications industry has resulted in four fixed network operators, six
mobile network operators and a number of non-exclusive telecommunications
services providers. Following the deregulation of the domestic market, the
external telecommunications market has been progressively liberalized since
1999. The Hong Kong government further issued licenses for domestic and
external telecommunications facilities in February 2000.

  In 1995, the Telecommunications Authority issued a written statement that
ISPs are required to be licensed under the Telecommunication Ordinance. An ISP
license does not authorize the licensee to provide external real-time voice
messages through the Internet. If an ISP provides services over the traditional
telephone network in Hong Kong, a PNETS license is required to operate this
business. The license is valid for twelve months only and is renewable at the
discretion of the OFTA of Hong Kong.

 Regulation in Taiwan

  Taiwan regulates IP telephony by licensing operators. A Type I license
operator may offer telecommunications services while a Type II license operator
must wait until further deregulation before it may offer IP telephony services
in the form of voice simple resale. Taiwan's regulatory agency, Directorate
General of Telecommunications, or DGT, has announced plans to deregulate
limitations that currently inhibit the offering of IP telephony services by a
Type II license operator. Currently, we do not directly offer IP telephony
services in Taiwan but have made such services available through our partner in
Taiwan who has a Type II license. If the anticipated deregulation does not
occur in 2001 as announced by DGT, or if our partner in Taiwan has not obtained
or maintained the proper license required after deregulation, we may not be
able to offer services in Taiwan. This would materially adversely affect the
financial condition, operating results, and future prospects of our business in
Taiwan.

  Direct trade between people in Taiwan and people in the PRC is prohibited
except that people in Taiwan may, after obtaining official approval, conduct
some business activities in the PRC. Our business may therefore be limited by
the foregoing restriction in some circumstances.

                                       50

 Other International Regulation

  The regulatory treatment of IP telephony outside of the United States varies
widely from country to country. A number of countries that currently prohibit
competition in the provision of voice telephony may also prohibit IP telephony.
Other countries permit but regulate Internet and IP telephony. Some countries
will evaluate proposed IP telephony service on a case-by-case basis and
determine whether it should be regulated as a voice service or as a different
telecommunications service. In many countries, IP telephony has not yet been
addressed by legislation or regulatory action. Increased regulation of the
Internet and/or ISPs and ICSPs, or the prohibition of Internet and IP
telephony, in one or more countries could materially adversely affect our
business, financial condition, operating results, and future prospects.

  As we make our services available in foreign countries, and as we facilitate
sales by our partners to end users located in foreign countries, some countries
may require us to qualify to do business in that country. Those countries may
also regulate our company or our services, including through requirements to
obtain authorization for the provision of voice telephony or other
telecommunications services or for the operation of telecommunications
networks. These countries may instead prohibit us in all cases from providing
our services or conducting our business as presently conducted or intended to
be conducted in those countries. Our failure to qualify as a foreign
corporation in a jurisdiction in which we are required to do so or to comply
with foreign laws and regulations could materially adversely affect our
business, financial condition, and results of operations, including by
subjecting us to taxes and penalties or by precluding us from, or limiting us
in, enforcing contracts in those jurisdictions.

  Our foreign partners may be, or become, subject to requirements to qualify to
do business in a particular country, to comply with regulations, including
requirements to obtain authorizations for the provision of voice telephony or
other telecommunications services or for the operation of telecommunications
networks, or to stop providing services or conducting their business as
presently conducted, or intended to be conducted, in that country. We cannot be
certain or assure you that our partners are in compliance, will be able to
comply, or will remain in compliance with these or similar requirements. The
failure of our partners to comply with these types of requirements could
materially adversely affect our business, financial condition, and results of
operations.

determined by the board of directors. Options will terminate before their
expiration date if the optionee is no longer an employee or consultant of oCen.
Please note that for purposes of calculating the potential realizable value, we
have done the following, in accordance with Securities and Exchange Commission
Rules:

  .  multiplied the number of shares subject to each option by $   , the
     assumed initial public offering price per share; and
  .  calculated the gains or "option spreads" that would exist for the
     options assuming an annual compounded stock appreciation of 5% and 10%
     from the date the option was granted over the full option term.

  These assumed annual compound rates are mandated by the Securities and
Exchange Commission and do not represent our estimate or projection of future
stock prices.

Employee Benefit Plans

2000 Stock Incentive Plan

  Introduction. Our 2000 Stock Incentive Plan is intended to serve as the
successor equity incentive program to our 1998 Stock Option/Stock Issuance
Plan. Our 2000 plan was adopted by our board on March 15, 2000 and approved by
the stockholders in      2000. Our 2000 plan will become effective on the date
the underwriting agreement for this offering is signed. At that time, all
outstanding options under the predecessor 1998 Stock Option/Stock Issuance Plan
will be transferred to our 2000 plan, and no further option grants will be made
under that predecessor plan. The transferred options will continue to be
governed by their existing terms, unless our compensation committee elects to
extend one or more features of our 2000 plan to those options. Except as
otherwise noted below, the transferred options will have substantially the same
terms as in effect for grants made under the discretionary option grant program
of our 2000 plan.

  Share Reserve.      shares of common stock have been authorized for issuance
under our 2000 plan. Such share reserve consists of the number of shares we
estimate will be carried over from our 1998 Stock Option/Stock Issuance Plan,
including the shares subject to outstanding options thereunder, plus an
additional increase of approximately      shares. The number of shares of
common stock reserved for issuance under our 2000 plan will automatically
increase on the first trading day in January each calendar year, beginning in
calendar year 2001, by an amount equal to   % of the total number of shares of
common stock outstanding on the last trading day in December of the preceding
calendar year, but in no event will any such annual increase exceed
shares. In addition, no participant in our 2000 plan may be granted stock
options, separately exercisable stock appreciation rights, or direct stock
issuances for more than      shares of common stock per calendar year.

  Equity Incentive Programs. Our 2000 plan is divided into five separate
components:

  .  the discretionary option grant program, under which eligible individuals
     in our employ or service may be granted options to purchase shares of
     common stock at an exercise price not less than 100% of the fair market
     value of those shares on the grant date;
  .  the stock issuance program, under which such individuals may be issued
     shares of common stock directly, through the purchase of such shares at
     a price not less than 100% of their fair market value at the time of
     issuance or as a bonus tied to the attainment of performance milestones
     or the completion of a specified period of service;
  .  the salary investment option grant program, under which our executive
     officers and other highly compensated employees may be given the
     opportunity to apply a portion of their base salary to the acquisition
     of special below-market stock option grants;
  .  the automatic option grant program, under which option grants will
     automatically be made at periodic intervals to our non-employee board
     members to purchase shares of common stock at an exercise price equal to
     100% of the fair market value of those shares on the grant date; and
  .  the director fee option grant program, under which our non-employee
     board members may be given the opportunity to acquire special below-
     market option grants.

  Eligibility. The individuals eligible to participate in our 2000 plan include
our officers and other employees, our non-employee board members, and any
consultants we hire.

  Administration. The discretionary option grant program and the stock issuance
program will be administered by the compensation committee, which shall be
divided into a primary committee and a secondary committee. This committee will
determine which eligible individuals are to receive option grants or stock
issuances under those programs, the time or times when such option grants or
stock issuances are to be made, the number of shares subject to each such grant
or issuance, the status of any granted option as either an incentive stock
option or a non-statutory stock option under the federal tax laws, the vesting
schedule to be in effect for the option grant or stock issuance and the maximum
term for which any granted option is to remain outstanding. The compensation
committee will also have the exclusive authority to select the executive
officers and other highly compensated employees who may participate in the
salary investment option grant program in the event that program is activated
for one or more calendar years.

                                       57
<PAGE>

  Plan Features. Our 2000 plan will include the following features:

  .  The exercise price for the shares of common stock subject to option
     grants made under our 2000 plan may be paid in cash or in shares of
     common stock valued at fair market value on the exercise date. The
     option may also be exercised through a same-day sale program without any
     cash outlay by the optionee. In addition, the plan administrator may
     provide financial assistance to one or more optionees in the exercise of
     their outstanding options or the purchase of their unvested shares by
     allowing such individuals to deliver a full-recourse, interest-bearing
     promissory note in payment of the exercise price and any associated
     withholding taxes incurred in connection with such exercise or purchase.

  .  The compensation committee will have the authority to cancel outstanding
     options under the discretionary option grant program, including options
     transferred from the 1998 plan, in return for the grant of new options
     for the same or a different number of option shares with an exercise
     price per share based upon the fair market value of our common stock on
     the new grant date.

  .  Stock appreciation rights are authorized for issuance under the
     discretionary option grant program. Such rights will provide the holders
     with the election to surrender their outstanding options for an
     appreciation distribution from us equal to the fair market value of the
     vested shares of common stock subject to the surrendered option, less
     the aggregate exercise price payable for those shares. Such appreciation
     distribution may be made in cash or in shares of common stock. None of
     the outstanding options under our 1998 plan contain any stock
     appreciation rights.

  .  The 2000 plan will include the following change in control provisions
     which may result in the accelerated vesting of outstanding option grants
     and stock issuances:

   .  In the event that we are acquired by merger or asset sale, each
      outstanding option under the discretionary option grant program which
      is not to be assumed by the successor corporation will automatically
      accelerate in full, and all unvested shares under the discretionary
      option grant and stock issuance programs will immediately vest, except
      to the extent our repurchase rights with respect to those shares are
      to be assigned to the successor corporation.

   .  The compensation committee will have complete discretion to structure
      one or more options under the discretionary option grant program so
      those options will vest as to all the option shares in the event those
      options are assumed in the acquisition but the optionee's service with
      us or the acquiring entity is subsequently terminated. The vesting of
      outstanding shares under the stock issuance program may be accelerated
      upon similar terms and conditions.

   .  The compensation committee will also have the authority to grant
      options which will immediately vest in the event we are acquired,
      whether or not those options are assumed by the successor corporation.

   .  The compensation committee may grant options and structure repurchase
      rights so that the shares subject to those options or repurchase
      rights will immediately vest in connection with a successful tender
      offer for more than 50% of our outstanding voting stock or a change in
      the majority of our board through one or more contested elections for
      board membership. Such accelerated vesting may occur either at the
      time of such transaction or upon the subsequent termination of the
      individual's service.

   .  The options currently outstanding under our 1998 plan will immediately
      vest in the event we are acquired by merger or sale of substantially
      all our assets, unless those options are assumed by the acquiring
      entity or our repurchase rights with respect to any unvested shares
      subject to those options are assigned to such entity. However, a
      number of those options also contain a special acceleration provision
      pursuant to which the shares subject to those options will immediately
      vest upon an involuntary termination of the optionee's employment
      within 18 months following an acquisition in which the repurchase
      rights with respect to those shares are assigned to the acquiring
      entity.

  Salary Investment Option Grant Program. In the event the compensation
committee elects to activate the salary investment option grant program for one
or more calendar years, each of our executive officers and other highly
compensated employees selected for participation may elect, prior to the start
of the calendar year, to reduce his or her base salary for that calendar year
by a specified dollar amount not less than $10,000 nor more than $50,000. Each
selected individual who files such a timely election will automatically be
granted, on the first trading day in January of the calendar year for which his
or her salary reduction is to be in effect, an option to purchase that number
of shares of common stock determined by dividing the salary reduction amount by
two-thirds of the fair market value per share of our common stock on the grant
date. The option will be exercisable at a price per share equal to one-third of
the fair market value of the option shares on the grant date. As a result, the
option will be structured so that the fair market value of the option shares on
the grant date less the exercise price payable for those shares will be equal
to the amount by which the optionee's salary is reduced under the program. The
option will become exercisable in a series of 12 equal monthly installments
over the calendar year for which the salary reduction is to be in effect.

  Automatic Option Grant Program. Under the automatic option grant program,
each individual who first becomes a non-employee board member at any time after
the completion of this offering will automatically receive an option grant for
     shares on the date such individual joins the board, provided such
individual has not been in our prior employ. In addition, on the date of each
annual stockholders meeting held after the completion of this offering, each
non-employee board member who is to continue to serve as a non-employee board
member, including each of our current non-employee board members, will
automatically be granted an option to purchase      shares of common stock,
provided such individual has served on our board for at least six months.

  Each automatic grant will have an exercise price per share equal to the fair
market value per share of our common stock on the grant date and will have a
term of 10 years, subject to earlier termination following the optionee's
cessation of board service. The option will be immediately exercisable for all
of the option shares; however, we may repurchase, at the exercise price paid
per share, any shares purchased under the option which are not vested at the
time of the optionee's cessation of board service. The shares subject to each
initial    -share automatic option grant will vest in a series of four
successive annual installments upon the optionee's completion of each year of
board service over the four-year period measured from the grant date. The
shares subject to each annual    -share automatic option grant will vest upon
the optionee's completion of one year of board service measured from the grant
date. However, the shares will immediately vest in full upon certain changes in
control or ownership or upon the optionee's death or disability while a board
member.

  Director Fee Option Grant Program. If the director fee option grant program
is activated in the future, each non-employee board member will have the
opportunity to apply all or a portion of any cash retainer fee for the year to
the acquisition of a below-market option grant. The option grant will
automatically be made on the first trading day in January in the year for which
the retainer fee would otherwise be payable in cash. The option will have an
exercise price per share equal to one-third of the fair market value of the
option shares on the grant date, and the number of shares subject to the option
will be determined by dividing the amount of the retainer fee applied to the
program by two-thirds of the fair market value per share of our common stock on
the grant date. As a result, the option will be structured so that the fair
market value of the option shares on the grant date less the exercise price
payable for those shares will be equal to the portion of the retainer fee
applied to that option. The option will become exercisable in a series of 12
equal monthly installments over the calendar year for which the election is to
be in effect. However, the option will become immediately exercisable for all
the option shares upon the optionee's death or disability while serving as a
board member.

  Our 2000 plan will also have the following features:

  .  Outstanding options under the salary investment and director fee option
     grant programs will immediately vest if we are acquired by a merger or
     asset sale or if there is a successful tender offer for

                                       59
<PAGE>

   more than 50% of our outstanding voting stock or a change in the majority
   of our board through one or more contested elections.

  .  Limited stock appreciation rights will automatically be included as part
     of each grant made under the salary investment option grant program and
     the automatic and director fee option grant programs, and these rights
     may also be granted to one or more officers as part of their option
     grants under the discretionary option grant program. Options with this
     feature may be surrendered to us upon the successful completion of a
     hostile tender offer for more than 50% of our outstanding voting stock.
     In return for the surrendered option, the optionee will be entitled to a
     cash distribution from us in an amount per surrendered option share
     based upon the highest price per share of our common stock paid in that
     tender offer.

  .  The board may amend or modify the 2000 plan at any time, subject to any
     required stockholder approval. The 2000 plan will terminate no later
     than the last business day of July 2010.

Employee Stock Purchase Plan.

  Introduction. Our Employee Stock Purchase Plan was adopted by the board on
March 15, 2000 and approved by the stockholders in      2000. The plan will
become effective immediately upon the signing of the underwriting agreement
for this offering. The plan is designed to allow our eligible employees and
the eligible employees of our participating subsidiaries to purchase shares of
our common stock, at semi-annual intervals, with their accumulated payroll
deductions.

  Share Reserve.      shares of our common stock will initially be reserved
for issuance. The reserve will automatically increase on the first trading day
in January each calendar year, beginning in calendar year 2001, by an amount
equal to 1% of the total number of outstanding shares of our common stock on
the last trading day in December in the prior calendar year. In no event will
any such annual increase exceed     shares.

  Offering Periods. The plan will have a series of successive overlapping
offering periods, with a new purchase interval beginning on the first business
day of February and August each year. Each purchase interval will have a
duration of 24 months, unless otherwise determined by the compensation
committee. However, the initial offering period may have a duration in excess
of 24 months and will start on the date the underwriting agreement for this
offering is signed and will end on the last business day in January 2002. The
next purchase interval will start on the first business day in August 2000.

  Eligible Employees. Individuals scheduled to work more than 20 hours per
week for more than five calendar months per year may join an offering period
on the start date of that period. However, employees may participate in only
one offering period at a time.

  Payroll Deductions. A participant may contribute up to 15% of his or her
cash earnings through payroll deductions, and the accumulated deductions will
be applied to the purchase of shares on each semi-annual purchase date. The
purchase price per share will be equal to 85% of the fair market value per
share on the participant's entry date into the offering period or, if lower,
85% of the fair market value per share on the semi-annual purchase date. Semi-
annual purchase dates will occur on the last business day of January and July
each year. However, a participant may not purchase more than     shares on any
purchase date, and not more than     shares may be purchased in total by all
participants on any purchase date. Our compensation committee will have the
authority to change these limitations for any subsequent offering period.

  Reset Feature. If the fair market value per share of our common stock on any
purchase date is less than the fair market value per share on the start date
of the two-year offering period, then that offering period will automatically
terminate, and a new two-year offering period will begin on the next business
day. All participants in the terminated offering will be transferred to the
new offering period.


                                      60
<PAGE>

  Change in Control. Should we be acquired by merger or sale of substantially
all of our assets or more than 50% of our voting securities, then all
outstanding purchase rights will automatically be exercised immediately prior
to the effective date of the acquisition. The purchase price will be equal to
85% of the market value per share on the participant's entry date into the
offering period in which an acquisition occurs or, if lower, 85% of the fair
market value per share immediately prior to the acquisition.

  Plan Provisions. The following provisions will also be in effect under the
plan:

  .  The plan will terminate no later than the last business day of July
     2010.
  .  The board may, at any time, amend, suspend, or discontinue the plan.
     However, certain amendments may require stockholder approval.

                             PRINCIPAL STOCKHOLDERS

  The following table sets forth information known to us with respect to
beneficial ownership of our common stock as of January 31, 2000, as adjusted to
reflect the sale of common stock offered hereby, by:

  . each person, or group of affiliated persons, known by us to own
    beneficially more than 5% of our outstanding common stock,
  . each of our directors,
  . each of our named executive officers, and
  . all directors and executive officers as a group.

  Except as otherwise noted, the address of each person listed in the table is
c/o oCen Communications, Inc., 4900 Rivergrade Road, C110, Irwindale, CA 91706.
Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission and includes voting and investment power
with respect to shares. To our knowledge, except under applicable community
property laws or as otherwise indicated, the persons named in the table have
sole voting and sole investment control with respect to all shares beneficially
owned. The applicable percentage of ownership for each stockholder is based on
14,406,116 shares of common stock outstanding as of January 31, 2000, assuming
the conversion of all outstanding preferred stock into common stock, and
shares outstanding after the completion of this offering, in each case together
with applicable options for that stockholder. Shares of common stock issuable
upon exercise of options and other rights beneficially owned that are
exercisable within 60 days of January 31, 2000 are deemed outstanding for the
purpose of computing the percentage ownership of the person holding those
options and other rights but are not deemed outstanding for computing the
percentage ownership of any other person. A portion of the shares issued to
officers or issuable upon exercise of options by officers is subject to
repurchase by us at the original exercise price in the event of termination of
that officers' employment, which repurchase right lapses over time.

                           RELATED PARTY TRANSACTIONS

  We have entered into indemnification agreements with our in-house legal
advisors.

  From our inception, we have funded losses and capital expenditures with cash
from financing activities. These activities included the private placement of
the following:

  . Common Stock. Common stock sold to our founders for an aggregate
    principal amount of approximately $200,000 in October 1997.

  . Convertible Notes. Convertible notes with an aggregate principal amount
    of approximately $280,000 sold to a group of private investors during
    fiscal years 1998 and 1999.

  . Series A. Convertible preferred stock sold to Baring Private Equity
    Partners, under the BAPEF Investments IV fund, and private investors for
    an aggregate amount of approximately $2 million in November 1998.

  . Series B. Convertible preferred stock sold to Excel-Foundation, a wholly
    owned subsidiary of New World Cyberbase, and Anderson Information
    Technology, for an aggregate amount of approximately $6.5 million in
    September 1999.

  . Series C. Convertible preferred stock sold to existing stockholders,
    Lotus Asset Management under the Lotus Liberator Fund, and private
    investors for an aggregate amount of approximately $2.2 million in
    November 1999.

  . Series D. Convertible preferred stock sold to existing stockholders for
    an aggregate amount of approximately $8 million in January 2000.

  . Convertible Notes. Convertible notes with an aggregate principal amount
    of $10 million sold to a group of private investors in January 2000.

  The number of shares of common stock and convertible preferred stock below
reflects a 10,000 for one stock split in August 1998 and 3-for-1 stock split in
April 1999.

  In October 1997, we issued an aggregate of 4,888,800 shares of common stock
for an aggregate purchase price of approximately $200,000 to our founders. We
also issued convertible notes with an aggregate principal amount of
approximately $280,000 during fiscal years 1998 and 1999. These notes bear
interest at the rate of 5.5% annually and expire in July 2001. In the event of
a qualified financing of at least $1 million in gross proceeds, the noteholders
have the option to convert these notes into equity securities at the same price
as the securities issued in the qualified financing. Approximately $230,000 of
the notes outstanding were converted into 186,234 shares of Series A preferred
stock in November 1998.

  In November 1998, we issued 1,600,023 shares of Series A convertible
preferred stock for $2 million, which included the conversion of some
promissory notes in November 1998. In connection with this offering, we issued
a warrant to purchase shares of Series A preferred stock if we did not meet
certain revenue milestones. The warrant became fully vested, immediately
exercisable and unable to be forfeited on July 31, 1999, when we did not meet
these milestones. The warrant was exercised in August 1999, and we issued
1,312,480 shares of Series A preferred stock.

  In September 1999, we issued 3,403,141 shares of Series B convertible
preferred stock for $6.5 million to a subsidiary of New World Cyberbase and to
Anderson Information Technology.

  In November 1999, we issued 1,023,807 shares of Series C convertible
preferred stock for $2.2 million to Lotus Asset Management, a group of private
investors, and existing stockholders.

                                       64
<PAGE>

  In January 2000, we issued 1,066,665 shares of Series D convertible preferred
stock to existing stockholders for approximately $8 million.

  In January 2000, we issued $10 million in aggregate principal amount of
convertible notes bearing interest at 6% annually to a group of private
investors. If we receive gross proceeds of at least $10 million in another
round of financing, then 30% of the outstanding principal amount of each note
will convert into our capital stock with the rest of the balance paid out by
us. If we consummate an initial public offering prior to January 2005, receive
gross proceeds of at least $10 million in another round of financing, or
default under the terms of the notes, then we, in our sole discretion, can
convert the entire outstanding amount of the notes into our capital stock.

  All shares of our preferred stock will convert into common stock on a  -for-
basis upon completion of this offering. Shares and warrants held by affiliated
persons and entities have been aggregated. See "Principal Stockholders." In
connection with the above transactions, we entered into agreements with the
investors providing for registration rights with respect to these shares. See
"Description of Capital Stock--Registration Rights."

  The Baring Asia Private Equity Fund is an investor in both our company and
NetStar. Jean Salata, the founder and managing partner of that fund, is one of
our directors. He is also the chairman of NetStar. We have entered into a
strategic marketing relationship with NetStar.

  During the period ended September 30, 1998 and 1999, stockholders and other
parties related to oCen loaned us approximately $230,000 and $50,000,
respectively, in exchange for notes convertible into our equity securities.
These notes are unsecured, bear interest at 5.5% annually, and mature during
various months in the year 2001. In connection with our Series A preferred
stock financing, notes totaling approximately $230,000, plus accrued interest
of $2,790, were converted into 186,234 shares of Series A preferred stock. We
repaid the remaining note for $50,000.

  At September 30, 1998 and 1999, we held notes receivable from employees,
directors, and major stockholders totaling $61,040 and $65,709, respectively,
for the purchase of common stock. The notes are unsecured, bear interest at
5.5% per year, and mature on September 29, 2001.

  Any future transactions, including loans between our company and our
officers, directors, and principal stockholders and their affiliates, will be
approved by a majority of the board of directors, including a majority of the
independent and disinterested directors, and will be on terms no less favorable
to us than could be obtained from unaffiliated third parties.

                          DESCRIPTION OF CAPITAL STOCK

  The following description of our capital stock and provisions of our
certificate of incorporation and our bylaws are summaries and are qualified by
reference to the provisions of our certificate of incorporation and our bylaws.
Copies of these documents have been or will be filed with the Securities and
Exchange Commission as exhibits to our registration statement, of which this
prospectus forms a part. The description of our capital stock reflects changes
to our capital structure that will occur upon the closing of this offering in
accordance with the terms of our certificate of incorporation.

  Our authorized capital stock consists of 27,850,000 shares of common stock,
par value $0.001 and 11,700,000 shares of preferred stock, par value $0.001.

Common Stock

  As of January 31, 2000, 14,406,116 shares of common stock were outstanding,
assuming conversion of all outstanding shares of convertible preferred stock
into common stock, held of record by 28 stockholders. After the offering,
shares will be outstanding. Upon consummation of this offering, all shares of
our existing convertible preferred stock will convert into common stock.

  In connection with our credit facility, we issued to the lender a warrant to
purchase 80,000 shares of Series A convertible preferred stock at $1.25 per
share, which would be equivalent to    shares of common stock upon consummation
of this offering. In June 1999, the warrant became fully vested, exercisable,
and unable to be forfeited.

  Holders of common stock are entitled to receive dividends as may from time to
time be declared by the board of directors out of funds legally available.
Holders of common stock are entitled to one vote per share on all matters on
which the holders of common stock are entitled to vote and do not have any
cumulative voting rights. Holders of common stock have no preemptive,
conversion, redemption or sinking fund rights. In the event of a liquidation,
dissolution or winding up of oCen, holders of common stock are entitled to
share equally and ratably in our assets, if any, remaining after the payment of
all our liabilities and the liquidation preference of any outstanding class or
series of preferred stock. The outstanding shares of common stock are, and the
shares of common stock offered by us in the offering when issued will be, fully
paid and nonassessable. The rights, preferences and privileges of holders of
common stock are subject to the rights of any series of preferred stock that we
may issue in the future, as described below.

Preferred Stock

  The board of directors has the authority to issue preferred stock in one or
more series and to fix the number of shares constituting any series and the
preferences, limitations and relative rights, including dividend rights,
dividend rate, voting rights, terms of redemption, redemption price or prices,
conversion rights and liquidation preferences of the shares constituting any
series, without any further vote or action by our stockholders. The issuance of
preferred stock by the board of directors could adversely affect the rights of
holders of common stock.

Registration Rights

  Under the terms of an agreement with some of our stockholders, after the
closing of this offering the holders of 8,406,116 shares of common stock will
be entitled to demand the registration of their shares under the Securities Act
of 1933. The holders of 50% of such shares are entitled to demand that we
register their shares under the Securities Act of 1933 subject to limitations
described in the relevant agreement. We are not required to effect more than
one demand registration for these stockholders. In addition, after the closing
of this offering, these holders will be entitled to piggyback registration
rights with respect to the registration of their shares of common stock. If we
propose to register any shares of common stock either for our account or for
the

                                       66
<PAGE>

account of other security holders, the stockholders with piggyback rights are
entitled to receive notice of the registration and are entitled to include
their shares in the registration, subject to some limitations. Further, at any
time after we become eligible to file a registration statement on Form S-3, the
holders of the registrable securities may require us to file registration
statements under the Securities Act of 1933 on Form S-3 with respect to their
shares of our common stock. These registration rights are subject to conditions
and limitations, among which is the right of the underwriters of an offering to
limit the number of shares of common stock held by stockholders with
registration rights to be included in a registration. We are generally required
to bear all of the expenses of these registrations, including the reasonable
fees of a single counsel acting on behalf of all selling stockholders, but
excluding underwriting discounts and commissions. Registration of any of the
shares of our common stock held by stockholders with registration rights would
result in those shares becoming freely tradable without restriction under the
Securities Act of 1933 immediately upon the effectiveness of that registration.

Stockholder Action; Special Meeting of Stockholders

  The Delaware certificate of incorporation that will become effective
immediately prior to the effectiveness of this offering states that
stockholders may not take action by written consent, but only at duly called
annual or special meetings of stockholders. The Delaware certificate of
incorporation also provides that special meetings of stockholders may be called
only by a majority of the board of directors.

Advance Notice Requirements For Stockholder Proposals and Director Nominations

  The bylaws provide that stockholders must provide timely notice in writing to
bring business before an annual meeting of stockholders or to nominate
candidates for election as directors at an annual meeting of stockholders. To
be timely notice for an annual meeting, a stockholder's notice must be
delivered to or mailed and received at our principal executive offices at least
120 days before the first anniversary of the date our notice of the previous
year's annual meeting of stockholders was provided to stockholders. If the date
of the annual meeting of stockholders has been changed to be more than 30
calendar days before or more than 70 calendar days after that anniversary,
notice by the stockholder, to be timely, must be received at least 90 days but
no earlier than 120 days before the annual meeting of stockholders or 10 days
following the date on which notice of the date of the meeting is made public.
If, at any annual meeting, the number of directors to be elected to the board
of directors is increased and we do not publicly announce all the nominees or
specify the size of the increased board of directors at least 100 days before
the anniversary of the previous year's annual meeting, a stockholder's notice
will be considered timely, but only with respect to nominees for the new
positions created by the increase provided the notice is received no later than
10 days after the nominees are announced to the public. To be a timely notice
for a special meeting at which one or more directors will be elected to the
board of directors, a stockholder's notice must be delivered to us no later
than 10 days after notice of the date of the meeting and the nominees proposed
to be elected are announced to the public. The bylaws also specify requirements
as to the form and content of a stockholder's notice. These provisions may keep
stockholders from bringing matters before an annual meeting of stockholders or
from making nominations for 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 issuances without stockholder approval. These additional
shares may be used for a variety of corporate purposes, including future public
offerings to raise additional capital, corporate acquisitions and employee
benefit plans. The existence of authorized but unissued shares of common stock
and preferred stock could make it harder or discourage an attempt to obtain
control of us by a proxy contest, tender offer, merger, or otherwise.

 Change of Control Provisions in Employee Benefit Plans

  The 2000 Plan provides that in the event that we merge with or into another
corporation or sell substantially all of our assets, the successor corporation
will assume or substitute each option or stock purchase

                                       67
<PAGE>

right, or SPR. If the outstanding options or SPRs are not assumed or
substituted, the administrator will provide notice to the optionee that he or
she has the right to exercise the option or SPR as to all of the shares subject
to the option or SPR, including shares which would not otherwise be
exercisable, for a period of fifteen days from the date of the notice. The
option or SPR will terminate upon the expiration of the fifteen-day period.

 Delaware Anti-Takeover Law and Charter Provisions

  We are subject to Section 203 of the Delaware General Corporation Law which
generally prohibits a Delaware corporation from engaging in any business
combination with any interested stockholder for a period of three years
following the date that the stockholder became an interested stockholder.
Section 203 applies unless:

  . prior to the date the stockholder became an interested stockholder, the
    board of directors of the corporation approved either the business
    combination or the transaction that resulted in the stockholder becoming
    an interested stockholder;
  . upon consummation of the transaction which resulted in the stockholder
    becoming an interested stockholder, the interested stockholder owned at
    least 85% of the voting stock of the corporation outstanding at the time
    the transaction commenced, excluding certain shares; or
  . on or after the date the stockholder became an interested stockholder,
    the business combination is approved by the board of directors and
    authorized at a meeting of stockholders by the affirmative vote of at
    least 66/3% of the outstanding voting stock that is not owned by the
    interested stockholder.

  Provisions of our certificate of incorporation and Delaware law may delay,
defer or prevent a change in our control and may adversely affect the voting
and other rights of holders of common stock. In particular, our certificate of
incorporation provides for a classified board of directors and the inability of
stockholders to vote cumulatively for directors.

 Limitation on Directors' Liability and Indemnification Matters

  Our certificate of incorporation provides that, except to the extent provided
by Delaware law, our directors will not be personally liable to us or our
stockholders for monetary damages for any breach of fiduciary duty while
serving as directors. This provision also does not affect the directors'
responsibilities under Delaware corporate law or any other laws, such as the
Federal securities laws or state or Federal environmental laws. Insofar as the
indemnification for liabilities arising under the Securities Act may be
permitted to our directors or officers, we have been informed that in the
opinion of the Securities and Exchange Commission, indemnification is against
public policy as expressed in the Securities Act and is therefore
unenforceable.

  We have obtained liability insurance for our executive officers and directors
and have entered into indemnity agreements to indemnify our in-house legal
advisors in addition to the indemnification provided for in our certificate of
incorporation and bylaws. These agreements, among other things, indemnify them
for expenses, judgments, and fines and amounts paid in settlement that are
actually and reasonably incurred by them in any action, suit, or proceeding
arising out of their legal or professional services on our behalf.

Transfer Agent and Registrar

  The transfer agent and registrar for our common stock is Boston Equiserve.

                        SHARES ELIGIBLE FOR FUTURE SALE

  Prior to this offering, there has not been any public market for our common
stock, and no prediction can be made as to the effect, if any, that market
sales of shares of common stock or the availability of shares of common stock
for sale will have on the market price of our common stock. Sales of
substantial amounts of our common stock in the public market after the
offering, or the perception that sales could occur, could adversely affect the
market price of our common stock and our ability to raise equity capital in the
future on terms favorable to us.

  After the offering,      shares of our common stock will be outstanding,
assuming that the underwriters do not exercise the over-allotment option. Of
these shares, all of the      shares sold in this offering will be freely
tradable without restriction or further registration under the Securities Act,
unless these shares are purchased by "affiliates" as that term is defined in
Rule 144 under the Securities Act. The remaining shares of common stock held by
existing stockholders are "restricted securities" as that term is defined in
Rule 144 under the Securities Act. Restricted securities may be sold in the
public market only if registered or if they qualify for an exemption from
registration under Rules 144 or 701 under the Securities Act, which rules are
summarized below.

  The following table shows approximately when the      shares of our common
stock that are not being sold in this offering but which will be outstanding
when this offering is complete will be eligible for sale in the public market:

<TABLE>

     Eligibility of Restricted Shares

     <S>                                                                <C>
     180 days after the effective date ................................
</TABLE>

  Resale of most of the restricted shares that will become available for sale
in the public market starting 180 days after the effective date will be limited
by volume and other resale restrictions under Rule 144 because the holders are
our affiliates.

  Rule 144. In general, under Rule 144 as currently in effect, beginning 90
days after the date of this prospectus, a person who has beneficially owned
shares of our common stock for at least one year is entitled to sell, within
any three-month period, a number of shares that is not more than the greater
of:

  . 1% of the number of shares of common stock then outstanding, which will
    equal approximately      shares immediately after this offering; or
  . the average weekly trading volume of the common stock on the Nasdaq
    National Market during the four calendar weeks before a notice of the
    sale on Form 144 is filed.

  Sales under Rule 144 must also comply with manner of sale provisions and
notice requirements and are subject to the availability of current public
information about our company.

  Rule 144(k).  Under Rule 144(k), a person who has not been one of our
affiliates at any time during the 90 days before a sale, and who has
beneficially owned the restricted shares for at least two years, is entitled to
sell the shares without complying with the manner of sale, public information,
volume limitation or notice provisions of Rule 144.

  Rule 701. Subject to limitations on the aggregate offering price of a
transaction and other conditions, our employees, directors, consultants or
advisors who purchased shares from us, or to whom we granted options to acquire
our shares, under a stock option plan or other written agreement prior to the
date we become subject to the reporting requirements of the Securities Exchange
Act in reliance on Rule 701, can resell those shares 90 days after the
effective date of this offering in reliance on Rule 144, but without complying
with some of the restrictions, including the holding period, contained in Rule
144.


                                       69

  Lock-Up Agreements.  Our officers, directors, and some existing stockholders
will sign lock-up agreements under which they will agree not to transfer or
dispose of, directly or indirectly, any shares of common stock or any
securities convertible into or exercisable or exchangeable for shares of common
stock, for a period of 180 days after the date of this prospectus. However,
Lehman Brothers may, in its sole discretion, at any time, and without notice,
release all or any portion of the shares subject to these lock-up agreements.
For a more detailed description of these lock-up agreements, see
"Underwriting."

  Registration Rights.  Under the terms of an agreement with some of our
stockholders, after the closing of this offering, the holders of 8,406,116
shares of common stock will be entitled to demand the registration of their
shares under the Securities Act of 1933. The holders of 50% of such shares are
entitled to demand that we register their shares under the Securities Act of
1933 subject to limitations described in the relevant agreement. We are not
required to effect more than one registration for such holders pursuant to
these demand registration rights. In addition, after the closing of this
offering these holders will be entitled to piggyback registration rights with
respect to the registration of their shares of common stock. If we propose to
register any shares of common stock either for our account or for the account
of other security holders, the holders of shares having piggyback rights are
entitled to receive notice of the registration and are entitled to include
their shares in the registration, subject to some limitations. Furthermore, at
any time after we become eligible to file a registration statement on Form S-3,
the holders of the registrable securities may require us to file registration
statements under the Securities Act of 1933 on Form S-3 with respect to their
shares of our common stock. These registration rights are subject to conditions
and limitations, among which is the right of the underwriters of an offering to
limit the number of shares of common stock held by security holders with
registration rights to be included in such registration. We are generally
required to bear all of the expenses of all these registrations, including the
reasonable fees of a single counsel acting on behalf of all selling
stockholders, except underwriting discounts and selling commissions.
Registration of any of the shares of our common stock held by security holders
with registration rights would result in such shares becoming freely tradable
without restriction under the Securities Act of 1933 immediately upon
effectiveness of such registration.

  Stock Options.  Immediately after the closing of this offering, we intend to
file a registration statement under the Securities Act covering      shares of
our common stock reserved for issuance under our stock option plans.

                       MATERIAL UNITED STATES INCOME TAX
                       CONSEQUENCES FOR NON-U.S. HOLDERS

Overview

  The following general discussion summarizes certain of the material U.S.
federal income and estate tax aspects of the ownership and disposition of
common stock applicable to non-U.S. holders of common stock. In general, a
"non-U.S. holder" is a person other than:

  . a citizen or resident of the United States,
  . a corporation or other entity taxable as a corporation created or
    organized under the laws of the United States or any of its political
    subdivisions,
  . an estate the income of which is subject to U.S. federal income taxation
    regardless of its sources,
  . a trust if a U.S. court is able to exercise primary supervision over
    administration of the trust and one or more U.S. persons have authority
    to control all substantial decisions of the trust; or
  . a trust that has a valid election in effect under applicable U.S.
    Treasury regulations to be treated as a U.S. person.

  The discussion is based upon the Internal Revenue Code of 1986, as amended,
regulations of the Treasury Department, Internal Revenue Service rulings and
pronouncements and judicial decisions now in effect, all of which are subject
to change (possibly on a retroactive basis). The discussion does not address
aspects of U.S. federal taxation other than income and estate taxation and does
not address all aspects of federal income and estate taxation. The discussion
does not consider any specific facts or circumstances that may apply to a
particular non-U.S. holder and does not address all aspects of U.S. federal
income tax law that may be relevant to non-U.S. holders that may be subject to
special treatment under such law, such as insurance companies, tax-exempt
organizations, financial institutions, broker-dealers, certain U.S.
expatriates, controlled foreign corporations, passive foreign investment
companies or foreign personal holding companies.

  Persons considering the purchase of common stock should consult their tax
advisors concerning the application of U.S. federal income tax laws, as well as
the laws of any state, local or foreign taxing jurisdiction to their particular
situations.

Dividends

  In general, the gross amount of dividends paid to a non-U.S. holder will be
subject to U.S. withholding tax at a 30% rate, or any lower rate prescribed by
an applicable tax treaty, unless the dividends:

  . are effectively connected with a trade or business carried on by the non-
    U.S. holder within the United States and a Form 4224 is filed with the
    withholding agent, or
  . if a tax treaty applies, are attributable to a United Sates permanent
    establishment of the non-U.S. holder.

  If either exception applies, the dividend will be taxed at ordinary U.S.
federal income tax rates. A non-U.S. holder may be required to satisfy certain
certification requirements in order to claim the benefit of an applicable
treaty rate or otherwise claim a reduction of, or exemption from, the
withholding obligation under the above described rules. In the case of a non-
U.S. holder that is a corporation, effectively connected income may also be
subject to an additional branch profits tax, which is generally imposed on a
foreign corporation at a rate of 30% of the deemed repatriation from the United
States of "effectively connected earnings and profits" or such lower rate as an
applicable tax treaty may provide. To the extent a distribution exceeds our
current or accumulated earnings or profits, it will be treated first as a
return of the holder's tax basis, and then as a gain from the sale of a capital
asset. Any withholding tax on a distribution in excess of our accumulated
earnings or profits is refundable to the non-U.S. holder upon filing an
appropriate claim with the Internal Revenue Service.


                                       71

  Under current law, dividends paid to an address outside the United States are
presumed to be paid to a resident of such country (unless the payor has
knowledge to the contrary) for purposes of the withholding tax discussed above
and, under the current interpretation of United States Treasury regulations,
for purposes of determining the applicability of a tax treaty rate. For
dividends paid after December 31, 2000, a non-U.S. holder of common stock who
wishes to claim the benefit of an applicable treaty rate (and avoid backup
withholding as discussed below), will be required to satisfy applicable
certification and other requirements.

Disposition of Common Stock

  Generally, a non-U.S. holder will not be subject to U.S. federal income tax
on any gain recognized upon the disposition of common stock unless:

  . the gain is effectively connected with a trade or business carried on by
    the non-U.S. holder within the United States, or, alternatively, if a tax
    treaty applies, attributable to a United States permanent establishment
    maintained by the non-U.S. holder, in which case such gain will be
    subject to tax at the rates and in the manner applicable to U.S. persons,
    and, if the holder is a foreign corporation, the branch profits tax may
    also apply,
  . the common stock is disposed of by an individual non-U.S. holder, who
    holds the common stock as a capital asset and is present in the United
    States for 183 days or more in the taxable year of the disposition and
    certain other conditions are met, in which case such gain will be subject
    to a flat 30% tax, which may be offset by United States source capital
    losses even though the individual is not considered a resident of the
    United States, or
  . (A) we are or have been a "U.S. real property holding corporation" within
    the meaning of Section 897(c)(2)(A) of the Code at any time within the
    shorter of the five-year period preceding such disposition or such non-
    U.S. holder's holding period and (B) assuming that the common stock is
    "regularly traded on an established securities market" for U.S. federal
    income tax purposes, the non-U.S. holder held, directly or indirectly, at
    any time during the applicable period from clause (A) above, including on
    the date of disposition, more than 5% of the outstanding common stock. We
    are not and do not anticipate becoming a "U.S. real property holding
    corporation."

  Non-U.S. holders should consult applicable treaties, which may exempt from
U.S. taxation gains realized upon the disposition of common stock in certain
cases.

Estate Tax

  Common stock owned, or treated as owned, by an individual non-U.S. holder at
the time of death will be includible in the individual's gross estate for U.S.
federal estate tax purposes, and may be subject to U.S. federal estate tax,
unless an applicable treaty provides otherwise.

Information Reporting and Backup Withholding

  On October 6, 1997, the Internal Revenue Service issued final regulations
relating to withholding, information reporting and backup withholding that
unify current certification procedures and forms and clarify reliance
standards. The final regulations generally will be effective for payments made
after December 31, 2000.

  Except as provided below, this section describes rules applicable to payments
made on or before December 31, 2000. Backup withholding, which generally is a
withholding tax imposed at the rate of 31% on certain payments to persons that
fail to furnish the information required under the U.S. information reporting
and backup withholding rules, generally will not apply to (1) dividends paid to
non-U.S. holders that are subject to the 30% withholding discussed above, or
that are not so subject because a tax treaty applies that reduces or eliminates
such 30% withholding, or (2) dividends paid on the common stock to a non-U.S.
holder at an address outside the United States, unless the payor has actual
knowledge that the payee is a U.S. person. We will be required to report
annually to the Internal Revenue Service and to each non-U.S. holder the amount

                                       72
<PAGE>

of dividends paid to, and the tax withheld from, such holder, regardless of
whether any tax was actually withheld or whether withholding was required. The
information may also be made available to the tax authorities in the non-U.S.
holder's country of residence.

  In the case of a non-U.S. holder that sells common stock to or through a U.S.
office of a broker, the broker must backup withhold at a rate of 31% and report
the sale to the Internal Revenue Service, unless the holder certifies its non-
U.S. status under penalties of perjury or otherwise establishes an exemption.
In the case of a non-U.S. holder that sells common stock to or through the
foreign office of a U.S. broker, or a foreign broker with certain types of
relationships to the United States, the broker must report the sale to the
Internal Revenue Service (but not backup withhold) unless the broker has
documentary evidence in its files that the seller is a non-U.S. holder or
certain other conditions are met, or the holder otherwise establishes an
exemption. A non-U.S. holder will generally not be subject to information
reporting or backup withholding if such non-U.S. holder sells the common stock
to or through a foreign office of a non-U.S. broker.

  Any amount withheld under the backup withholding rules from a payment to a
holder is allowable as a credit against the holder's U.S. federal income tax,
which may entitle the holder to a refund, provided that the holder furnishes
the required information to the Internal Revenue Service. In addition, certain
penalties may be imposed by the Internal Revenue Service on a holder who is
required to supply information but does not do so in the proper manner.

  The final regulations eliminate the general, current legal presumption that
dividends paid to an address in a foreign country are paid to a resident of
that country. The final regulations impose certain certification and
documentation requirements on non-U.S. holders claiming the benefit, under a
tax treaty, of a reduced withholding rate on dividends.

  Prospective purchasers of the common stock are urged to consult their own tax
advisors as to the effect, if any, of the final regulations on their purchase,
ownership and disposition of the common stock.

  The closing of this offering is a condition to the closing of the
international offering, and the closing of the international offering is a
condition to the closing of this offering.

  The underwriting agreement provides that the obligations of the several
underwriters to purchase the shares included in the offering are subject to
approval of legal matters by counsel as well as to other conditions. It also
states that if any shares are purchased by the underwriters pursuant to the
underwriting agreement, then all of the shares which the underwriters have
agreed to purchase pursuant to the underwriting agreement must be purchased.
The underwriters expect to deliver the shares on or about     , 2000.

  The underwriters propose to offer the shares directly to the public at the
public offering price set forth on the cover page of this prospectus, and to
specified selected dealers, who may include the underwriters, at the public
offering price less a selling concession not in excess of $    per share. The
underwriters may allow, and the selected dealers may reallow, a concession not
in excess of $    per share on sales to specified brokers and dealers. After
the offering, the representatives may change the offering price and other
selling terms. If all of the shares are not sold at the initial offering price,
the representatives may change the public offering price and the other selling
terms. The representatives have advised us that the underwriters do not intend
to confirm any sales to any accounts over which they exercise discretionary
authority that exceed 5% of the total number of shares of common stock offered
by them.

  We estimate that the total expenses of the offering, including registration,
filing and listing fees, printing fees and legal and accounting expenses but
excluding the underwriting discount will be approximately $     million.

  We have granted to the underwriters an option to purchase up to an additional
shares of common stock, exercisable solely to cover over-allotments, if any, at
the public offering price less the underwriting discount

                                       74
<PAGE>

shown on the cover page of this prospectus. The option may be exercised at any
time until 30 days after the date of the underwriting agreement. To the extent
this option is exercised, each underwriter will be committed, subject to
various conditions, to purchase a number of additional shares proportionate to
its initial purchase commitment as indicated in the preceding table, and we
will be obligated, under the over-allotment option, to sell the shares to the
underwriters.

  We, our officers, directors and some existing stockholders have agreed not to
do any of the following, whether any transaction described below is to be
settled by delivery of common stock or other securities, in cash or otherwise,
in each case without the prior written consent of Lehman Brothers, on behalf of
the underwriters, for a period of 180 days after the date of this prospectus:

  . offer, sell, pledge or otherwise dispose of, or enter into any
    transaction which is designed or could be expected to, result in the
    disposition by any person at any time in the future of, any shares of
    common stock or securities convertible into or exchangeable for common
    stock or substantially similar securities, other than the following:
   . the common stock sold under this prospectus,
   . the common stock to be issued concurrently with the closing of this
     offering upon the mandatory conversion of our outstanding preferred
     stock, and
   . shares of common stock we issue pursuant to employee benefit plans,
     qualified stock option plans or other employee compensation plans
     existing on the date of this prospectus or pursuant to currently
     outstanding options, warrants or rights;
  . sell or grant options, rights or warrants with respect to any shares of
    our common stock or securities convertible into or exchangeable for our
    common stock or substantially similar securities, other than the grant of
    options pursuant to option plans existing on the date hereof; and
  . enter into any swap or other derivatives transaction that transfers to
    another, in whole or in part, any of the economic benefits or risks or
    ownership of shares of common stock.

  Prior to the offering, there has been no public market for the common stock.
The initial public offering price for the common stock will be determined by
negotiation between oCen and the representatives. Among the factors to be
considered in such negotiations are:

  . prevailing market conditions;
  . the market values of publicly traded companies that we and the
    underwriters believe to be comparable to oCen;
  . the current state of oCen's development and its current financial
    condition;
  . the history of and prospects for oCen and the Asian IP telephony
    industry; and
  . the prospects for future revenues and earnings of oCen.

  We have applied for quotation of the common stock on the Nasdaq National
Market under the symbol OCCM.

  Fidelity Capital Markets, a division of National Financial Services
Corporation, is acting as an underwriter in this offering and will be
facilitating electronic distribution of information through the Internet,
intranet and other proprietary electronic technology.

  Until the distribution of the shares is completed, rules of the Securities
and Exchange Commission may limit the ability of the underwriters and selling
group members to bid for and purchase shares. As an exception to these rules,
the representatives are permitted to engage in transactions that stabilize the
price of the shares. These transactions may consist of bids or purchases for
the purposes of pegging, fixing or maintaining the price of the shares.

  The underwriters may create a short position in the shares in connection with
the offering, which means that they may sell more shares than are set forth on
the cover page of this prospectus. If the underwriters create a short position,
then the representatives may reduce that short position by purchasing shares in
the open

                                       75
<PAGE>

market. The representatives also may elect to reduce any short position by
exercising all or part of the over-allotment option.

  The representatives may impose a penalty bid on certain underwriters and
selling group members. This means that if the representatives purchase shares
in the open market to reduce the underwriters' short position or to stabilize
the price of the shares, they may reclaim the amount of the selling concession
from the underwriters and selling group members who sold those shares as part
of the offering.

  In general, purchases of a security for the purpose of stabilization or to
reduce a syndicate short position could cause the price of the security to be
higher than it might otherwise be in the absence of those purchases. The
imposition of a penalty bid might also have an effect on the price of a
security to the extent that it were to discourage resales of the security by
purchasers in an offering.

  Neither we nor any of the underwriters make any representation or prediction
as to the direction or magnitude of any effect that the transactions described
above may have on the price of the shares. In addition, neither we nor any of
the underwriters make any representation that the representatives will engage
in such transactions or that such transactions, once commenced, will not be
discontinued without notice.

  This prospectus may be used in connection with offers and sales of shares
offered initially outside the United States insofar as those shares are
reoffered or resold from time to time in the United States in transactions that
require registration under the Securities Act.

  This prospectus is not, and under no circumstances is to be to construed as,
an advertisement or a public offering of the common stock in Canada or any
province or territory thereof. Any offer or sale of common stock in Canada may
only be made pursuant to an exemption from the dealer registration requirement
(where such an exemption is not available, offers shall be made only by a
registered dealer) in the relevant Canadian jurisdiction where any offer is
made.

  The common stock may not be offered or sold directly or indirectly in Hong
Kong by means of this document or any other offering material or document other
than to persons whose ordinary course of business it is to buy or sell shares
or debentures, whether as principal or as agent. Unless permitted to do so by
the securities laws of Hong Kong, no person may issue or caused to be issued in
Hong Kong this document or any amendment or supplement thereto or any other
information, advertisement or document relating to the common stock other than
with respect to common stock intended to be disposed of to persons outside Hong
Kong or to persons whose business involves the acquisition, disposal or holding
of securities, whether as principal or as agent.

  The common stock may not be offered and sold, directly or indirectly, in the
PRC or to any resident of the PRC.

  Purchasers of the common stock offered in this prospectus may be required to
pay stamp taxes and other charges under the laws and practices of the country
of purchase, in addition to the public offering price set forth on the cover of
this prospectus.

  We have agreed to indemnify the underwriters against specified liabilities,
including liabilities under the Securities Act, liabilities arising from
breaches of the representations and warranties contained in the underwriting
agreement, and liabilities incurred in connection with the directed share
program referred to below, and to contribute, under specified circumstances, to
payments that the underwriters may be required to make in respect thereof.

  At our request, Lehman Brothers has reserved up to shares of common stock,
or     % of the common stock offered by this prospectus, for sale pursuant to a
directed share program to officers, directors and employees, and their family
members, of oCen and its affiliates and friends of oCen's management. All of

                                       76
<PAGE>

the persons purchasing the reserved shares must commit to purchase no later
than the close of business on the day following the date of this prospectus.
The number of shares available for sale to the general public will be reduced
to the extent these persons purchase the reserved shares.

  Certain of the underwriters have provided from time to time, and expect to
provide in the future, financial advisory and investment banking services to us
and our affiliates, for which the underwriters have received and will receive
customary fees and commissions. ING Group and its affiliates own 16% of a
private equity fund that in turn owns approximately 20% of our existing share
capital. That fund's most recent investment in our company occurred in January
2000 when it acquired 400,000 additional shares of our capital stock. Jean
Salata, one of our directors, is a managing member of the general partner of
that fund. Lloyd Fischer, a director who owns approximately 1% of our existing
share capital, heads the Asian telecom investment banking team of ING Barings
and is a director of ING Barings Asia Limited.

                       Report of Independent Accountants

  To the Board of Directors and Stockholders of
  oCen Communications, Inc.

  In our opinion, the accompanying consolidated balance sheets and the
  related consolidated statements of operations, stockholders' equity
  (deficit) and cash flows present fairly, in all material respects, the
  financial position of oCen Communications, Inc. and its subsidiaries (the
  "Company") at September 30, 1998 and 1999, and the results of their
  operations and their cash flows for the period from October 14, 1997
  (Inception) through September 30, 1998 and for the year ended September 30,
  1999, in conformity with accounting principles generally accepted in the
  United States. These financial statements are the responsibility of the
  Company's management; our responsibility is to express an opinion on these
  financial statements based on our audits. We conducted our audits of these
  statements in accordance with auditing standards generally accepted in the
  United States, which require that we plan and perform the audit to obtain
  reasonable assurance about whether the financial statements are free of
  material misstatement. An audit includes examining, on a test basis,
  evidence supporting the amounts and disclosures in the financial
  statements, assessing the accounting principles used and significant
  estimates made by management, and evaluating the overall financial
  statement presentation. We believe that our audits provide a reasonable
  basis for the opinion expressed above.

                           OCEN COMMUNICATIONS, INC.

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
  (All interim information relating to the periods ended December 31, 1998 and
                               1999 is unaudited)

1. Business and Organization:

  oCen Communications, Inc. (the "Company") was incorporated in California in
October 1997 under the name Pacific Telekey Network, Inc., and subsequently
changed its name to oCen Communications, Inc. in October 1999. The Company
provides Internet Protocol ("IP") communication services over a managed IP
network.

  In December 1998, the Company established a wholly owned subsidiary, Well
Signal Development Limited ("Well Signal"), to provide IP communication
services in Hong Kong. The subsidiary's name has been legally changed to oCen
Communications HK Ltd., effective October 1999.

  In September 1999, the Company established a wholly owned subsidiary, oCen
Communications Taiwan, Ltd. ("oCen Taiwan"), to provide IP communication
services in Taiwan. The Company is awaiting formal approval of the
incorporation of oCen Communications in Taiwan.

  The accompanying consolidated financial statements have been prepared on the
basis that the Company will continue as a going concern. Since inception, the
Company has incurred significant operating losses and has generated negative
cash flows from operations; and, from time to time, has had negative working
capital. The Company has funded operations primarily through the sale of equity
securities and debt borrowings. Management believes that the proceeds received
through the sale of equity or debt securities, borrowings from existing credit
facilities and revenue generated from operations will be adequate to support
the Company's operations through March of 2001.

2. Summary of Significant Accounting Policies:

Principles of Consolidation and Basis of Presentation

  The consolidated financial statements include the accounts of oCen
Communications, Inc. and its aforementioned subsidiaries. All significant
intercompany accounts and transactions have been eliminated in consolidation.
Each of the Company's subsidiaries has a September 30 year end.

Use of Estimates

  In the normal course of preparing financial statements in conformity with
generally accepted accounting principles, management is required to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents

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

Fair Value of Financial Instruments

  The Company's financial instruments, including cash and cash equivalents,
accounts receivable, accounts payable, capital lease obligations and notes
payable are carried at cost, which approximates their fair value because of the
short-term maturity of these instruments and the relatively stable interest
rate environment.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
  (All interim information relating to the periods ended December 31, 1998 and
                               1999 is unaudited)


Property and Equipment

  Property and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation and amortization is computed using the straight-line
method based upon the estimated useful lives of the assets or lease terms, if
shorter, which are generally between 3 and 7 years. Useful lives are evaluated
regularly by management in order to determine recoverability in light of
current technological conditions. Maintenance and repairs are charged to
expense as incurred. Upon the sale or retirement of property and equipment, the
accounts are relieved of the cost and the related accumulated depreciation,
with any resulting gain or loss included in the Consolidated Statement of
Operations.

Long-Lived Assets

  The Company reviews its long-lived assets for impairment whenever events or
changes in circumstances indicate the carrying amount of such assets may not be
recoverable. Recoverability of these assets is determined by comparing the
forecasted undiscounted cash flows attributable to such assets to their
carrying value. If the carrying value of the assets exceeds the forecasted
undiscounted cash flows, then the assets are written down to their fair value.
Fair value is determined based on discounted cash flows or appraised values,
depending upon the nature of the assets. To date, there have been no such
impairments.

Revenue Recognition

  The Company's revenues are principally derived from the sale of calling cards
to distributors, marketed through traditional and online channels. The
distributors resell the calling cards to third parties who in turn sell the
calling cards to end users. Revenues are recognized as minutes (or fractions
thereof) are delivered to end users provided that no significant Company
obligations remain and collection of the related receivable from the
distributor is probable.

  Customer payments received in advance for prepaid services and services to be
supplied under contractual agreements are deferred and recognized as services
are provided.

Cost of Revenues

  Cost of revenues primarily consist of access, transmission and termination
costs, and are expensed as incurred.

General and Administrative

  General and administrative expenses include salaries, employee benefits and
expenses for executive, finance, and human resources personnel. In addition,
general and administrative expenses include fees for professional services and
occupancy costs. These costs are expensed as incurred.

Sales and Marketing

  Sales and marketing expenses consist primarily of expenses relating to
salaries, payroll taxes, benefits, commissions for sales and marketing
personnel and advertising costs. These costs are expensed as incurred. For the
period from October 14, 1997 (Inception) to September 30, 1998, for the year
ended September 30, 1999 and for the three months ended December 31, 1998 and
1999, advertising expenses amounted to approximately $540, $50,725, $3,791 and
$102,598, respectively.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
  (All interim information relating to the periods ended December 31, 1998 and
                               1999 is unaudited)


Product Development

  Product development costs consist primarily of salaries and related expenses
for engineers and information technology personnel, software developers,
consulting fees, lab costs and market research. These costs are expensed as
incurred.

Income Taxes

  The Company utilizes the liability method of accounting for income taxes.
Under this method, deferred tax liabilities and assets are determined based on
the difference between the financial statement and the tax bases of assets and
liabilities using enacted tax rates in effect for the period in which the
differences are expected to reverse. Valuation allowances are established, when
necessary, to reduce deferred tax assets to the amount expected to be realized.

Net Loss Per Share

  Net loss per share is computed by dividing the net loss for the period by the
weighted average number of common shares outstanding. Shares associated with
stock options, warrants and convertible instruments are not included to the
extent they are antidilutive.

Unaudited Pro Forma Net Loss Per Share

  Unaudited pro forma net loss per share for the year ended September 30, 1999
and for the three months ended December 31, 1999, is computed by dividing the
net loss for the period by the weighted average number of shares of common
stock outstanding, including the pro forma effects of the automatic conversion
of the Company's convertible preferred stock into shares of the Company's
common stock effective at the time of the Company's initial public offering as
if such conversion occurred on October 1, 1998 and 1999, respectively, or at
the date of original issuance, if later.

Stock-Based Compensation

  The Company accounts for stock-based employee compensation arrangements in
accordance with the provisions of Accounting Principles Board ("APB") No. 25,
"Accounting for Stock Issued to Employees," and complies with the disclosure
requirements of SFAS No. 123, "Accounting for Stock-Based Compensation." Under
APB No. 25, compensation cost, if any, is recognized over the respective
vesting period based on the difference, on the date of grant, between the fair
value of the Company's common stock and the grant price. The Company accounts
for stock issued to non-employees in accordance with the provisions of SFAS No.
123 and Emerging Issues Task Force ("EITF") 96-18.

Comprehensive Income

  The Company adopted the provisions of SFAS No. 130, "Reporting Comprehensive
Income" in the fiscal year ended September 30, 1999. Comprehensive income
generally represents all changes in stockholders' equity (deficit) during the
period except those resulting from investments by, or distributions to,
stockholders. To date, there have been no such significant changes in
stockholders' equity (deficit) other than net loss amounts.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
  (All interim information relating to the periods ended December 31, 1998 and
                               1999 is unaudited)


Foreign Currency Translation

  During fiscal year 1999, the Company established two foreign subsidiaries.
Translation of foreign currencies are accounted for using the US Dollar as the
functional currency of the Company's foreign subsidiaries, however, books of
record are maintained in the local currencies. Foreign currency translations
occur during remeasurement of the books of record into the functional currency.
To date, the Company's customer contracts have been denominated in U.S.
dollars, and the operating assets and liabilities of the Company's foreign
subsidiaries have been minimal. As a result, there have been no significant
foreign currency translation adjustments required to be reflected in
stockholders' equity (deficit).

Unaudited Interim Financial Information

  The interim consolidated financial statements of the Company for the three
months ended December 31, 1998 and 1999, included herein have been prepared by
the Company, without audit, pursuant to the rules and regulations of the
Securities and Exchange Commission. Certain information and footnote
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles have been condensed or omitted
pursuant to such rules and regulations relating to interim financial
statements. In the opinion of management, the accompanying unaudited interim
consolidated financial statements reflect all adjustments, consisting only of
normal recurring adjustments, necessary to present fairly the financial
position of the Company at December 31, 1999 and the results of its operations
and its cash flows for the three months ended December 31, 1998 and 1999.

Recent Accounting Pronouncements

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

  In April 1998, the AICPA issued SOP No. 98-5, "Reporting on the Costs of
Start-Up Activities." SOP No. 98-5 requires that all start-up costs related to
new operations must be expensed as incurred. In addition, start-up costs that
were capitalized in the past must be written off when SOP No. 98-5 is adopted.
The adoption of SOP No. 98-5 during the third quarter of fiscal 1998 did not
have a significant impact on the Company's financial position, results of
operations or cash flows.

3. Concentration of Credit Risk, Significant Customers and Geographic
Information:

  Financial instruments which subject the Company to concentrations of credit
risk consist primarily of cash and cash equivalents and trade accounts
receivable. The Company maintains its cash and cash equivalents with major
financial institutions; at times, such balances with any one financial
institution may exceed FDIC insurance limits. The Company's accounts receivable
are derived from revenue earned from customers primarily located in the United
States. Although a majority of the Company's customers prepay for services, if
necessary, the Company extends differing levels of credit to customers and
generally does not require collateral. The Company maintains reserves for
potential credit losses based upon the expected collectibility of accounts
receivable. To date, such losses have been within management's expectations.

</TABLE>

  At September 30, 1999, the Company had receivable balances from Abest
International and Abest Communications, Inc. ("Abest") and STE Communications
approximating 62% and 12% of total accounts receivable, respectively. At
December 31, 1999, the Company had receivable balances from Abest, STE
Communications and Star Communications approximating 51%, 18% and 10% of total
accounts receivable, respectively.

  As of December 31, 1999, the Company's largest customer, Abest, owed the
Company $815,430, most of which was past due. The Company believes that non-
payment is a result of a lack of liquidity at Abest. In January 2000, Abest
sold substantially all of its assets to Tianrong Internet Products and Services
("TIPS"), an over-the-counter publicly traded company, in exchange for
restricted common stock of TIPS. However, TIPS did not assume any of Abest's
liabilities. Although the Company is currently negotiating with Abest to
collect amounts due the Company, the Company cannot assess the ultimate
collectibility of this balance and as such has deferred all revenue relating to
the outstanding uncollected receivable balance from Abest at December 31, 1999
as a result of the uncertainty surrounding the collection of such amount and
will recognize revenue upon the collection of the receivable balance from
Abest. Deferred revenue related to the uncollected Abest receivable at December
31, 1999 represented approximately 36% of our total deferred revenue. The
Company intends to vigorously continue its collection efforts.

  The Company operates in one industry segment providing IP telephony
communications services. The Company's business operations are principally
based in the United States and there were no foreign operations during the
period October 14, 1997 (Inception) though September 30, 1998. For the year
ended September 30, 1999 and three months ended December 31, 1999, all of the
Company's revenues were generated within the United States.

  Long-lived assets, excluding accumulated depreciation and amortization, by
geographical location at September 30, 1999 and December 31, 1999 are as
follows:

4. Credit Facilities:

  In April 1999, the Company executed a $1,000,000 lease line credit facility
(the "Facility") with a lender to refinance certain equipment purchases. The
Facility is segregated into two $500,000 tranches, one immediately available to
the Company and the second subject to certain conditions as set forth in the
Facility. In connection with the Facility, the Company issued a warrant to the
lender to purchase 80,000 shares of its Series A preferred stock at an exercise
price of $1.25 (See Note 12). In June 1999, the Company borrowed under the
first tranche by refinancing equipment purchases of approximately $480,000 and
$19,000 under two separate lease agreements (See Note 7). These leases bear
interest at a rate of approximately 11% per annum, which amounted to interest
expense of approximately $11,000 for the year ended September 30, 1999. As of
September 30, 1999, the Company had not borrowed under the second tranche of
the Facility, and on December 31, 1999, the unused portion of the Facility
expired.

 In June 1999, the Company executed a Senior Loan and Security Agreement (the
"Agreement") with a lender under which the Company could refinance up to
$1,000,000 of qualified equipment purchases through December 31, 1999, or April
30, 2000 if extended. The purchase period was not extended and expired on
December 31, 1999. In June 1999, the Company borrowed under the credit facility
and executed two individual notes in favor of the lender for approximately
$169,000 and $148,000. The notes bear interest at approximately 17% per annum,
mature in June 2002, are collateralized by the purchased equipment and are
payable in 36 monthly installments. Upon maturity of each note, the Company has
the option to either extend the note for an additional 12 months or make one
final lump sum payment. As of September 30, 1999, the aggregate outstanding
principal balance of these notes amounted to approximately $279,000, of which
approximately $79,000 is current.

  In November 1999, the Company executed a $1,000,000 equipment lease line (the
"Line") with a lender. The term of the Line is 36 months with payments due on
the first day of each month. The rate is 3.20% of the applicable equipment cost
per month. As of December 31, 1999, the Company had no borrowings against the
Line.

  In January 2000, the Company agreed to a $1,000,000 equipment lease line (the
"Equipment Line") with a lender. The Equipment Line may be utilized by the
Company through June of 2000 and bears interest at the yield on 36-month U.S.
Treasury Notes, as quoted by the bank, plus 300 basis points. In connection
with the execution of the Equipment Line, the Company expects to grant warrants
to the lender to purchase 5,333 shares of the Company's Series D Preferred at
an exercise price of $7.50 per share. As of March 2000, the two parties had not
finalized the Equipment Line.

Litigation

  From time to time, the Company has been party to various litigation and

other fixed assets from Giant Joint International Limited, located in Hong
Kong, and from Nations Tech Co., located in Taiwan, respectively, for a total
cash consideration of approximately $215,000. The total consideration was
allocated to the individual assets based on their estimated fair values at the
dates of purchase.

9. Income Taxes:

  As a result of net operating losses, the Company has not recorded a provision
for income taxes. Significant components of the Company's deferred taxes
consisted of the following at September 30, 1998 and 1999:

</TABLE>

  Due to uncertainty surrounding the realization of the benefits in future tax
returns, the Company placed a full valuation allowance against its deferred tax
assets as of September 30, 1998 and 1999.

  As of September 30, 1999, the Company had federal and state net operating
loss carryforwards of approximately $2,915,120 each. The federal net operating
loss carryforwards will begin to expire in 2018, and the state net operating
loss carryforwards will begin to expire in 2003. The Company's ability to
utilize net operating loss carryforwards may be limited in the event that a
change in ownership, as defined in the Internal Revenue Code, occurs in the
future.

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

Dividends

  Each share of Series A, Series B and Series C Preferred Stock provides for
discretionary, noncummulative dividends of $0.075, $0.115 and $0.126 per share,
per annum, respectively.

Conversion

  Each share of Preferred Stock is convertible into shares of common stock at
the option of the holder at any time after the date of issuance of such shares.
Each share of Series A , Series B and Series C Preferred Stock will
automatically convert to common stock upon the consummation of the Company's
initial public offering ("IPO") of common stock if the Company receives gross
proceeds of at least $10,000,000 and the offering price per share is at least
$4.20, or upon approval by 67% of the holders of each class of Preferred Stock.

Voting

  Each share of Series A, Series B and Series C Preferred Stock is entitled to
the number of votes equal to the number of shares of common stock that could be
converted on the date of vote.

Redemption

  The Preferred Stock is not redeemable.

Liquidation

  Upon liquidation (as defined), the holders of Series A, B and C Preferred
Stock would receive $1.25, $1.91 and $2.10 per share, respectively, plus an
amount equal to 6% of the Preferred Stock issuance price per annum accruing
from the date of original issuance until payment. If at the time of liquidation
the assets and funds to be distributed are insufficient to permit the above
disbursement, then the entire available assets and funds shall be distributed
ratably among the preferred stockholders in proportion to the full amounts to
which they would otherwise be entitled.

Shares Issued for Services

  In connection with an agreement with a third party, the Company issued
488,880 shares of common stock for services provided in fiscal year 1998. At
the date of issuance, the shares were valued at the deemed fair value for
accounting purposes, resulting in a charge of $24,444, which is included in
general and administrative expense in the accompanying Consolidated Statement
of Operations for the period from October 14, 1997 (Inception) through
September 30, 1998.

11. Stock Options:

Stock Option Plans

  In September of 1998, the Company adopted the 1998 Stock Option/Stock
Issuance Plan (the "Plan") which is divided into two separate equity programs,
the Option Grant Program and the Stock Issuance Program.

  The Option Grant Program provides for the issuance of nonqualified and
incentive stock options to employees, non-employee members of the board and
consultants. The exercise price per share is not to be less than 85% of the
fair market value per share of the Company's common stock on the date of grant
for nonqualified stock options. Incentive stock options may not be granted at
less than 100% of the fair market value of the Company's common stock on the
date of grant (110% if granted to an employee who owns 10% or more of the
common stock). Options generally begin vesting six months after the vesting
start date, generally the employees date of hire, and generally vest ratably
over a four-year period and expire ten years from the date of grant. In
addition, certain employees have options that vest immediately. In the event
the holder of the option ceases to be employed by the Company, all unvested
options are forfeited, all vested options may be exercised within a period of
up to 3 months after termination and any options exercised for unvested shares
of common stock are subject to repurchase by the Company at the original
exercise price. The Company had 416,250 unvested shares of common stock issued
and outstanding under the plan at September 30, 1999 which were subject to
repurchase by the Company at the related exercise prices. Under the terms of
the Plan, as amended in January 1999, options to purchase 2,611,200 shares of
common stock were reserved. As of September 30, 1999, options to purchase
806,230 shares of common stock were available for future grant.

  The Stock Issuance Program provides for shares of common stock to be issued
directly through either the immediate purchase of shares or as a bonus for
services rendered. The purchase price per share is not to be less than 85% of
the fair market value per share of the Company's common stock on the date of
grant. The purchase price if granted to an employee who owns 10% or more of the
common stock must be granted at no less than 110% of the fair market value of
the Company's common stock on the date of grant. Vesting of common stock issued
is discretionary. In the event the holder ceases to be employed by the Company,
all unvested common stock shall be forfeited and any cash paid related to the
unvested shares will be repaid by the Company.

  Options granted for the period from October 14, 1997 (Inception) through
September 30, 1998, for the year ended September 30, 1999 and for the three
months ended December 31, 1999 resulted in total deferred compensation of $
494,560, $ 535,548, and $785,378, respectively, and were recorded as deferred
compensation in stockholder's equity. This deferred compensation represented
the difference between the deemed fair value of the Company's common stock for
accounting purposes and the exercise price of these options at the date of
grant. The deferred stock compensation is recognized as stock-based
compensation in the Consolidated Statements of Operations over the related
vesting periods of the options.

  For the period from October 14, 1997 (Inception) through September 30, 1998,
for the year ended September 30, 1999 and for the three months ended December
31, 1998 and 1999, stock-based compensation included in the Consolidated
Statements of Operations amounted to $199,123, $490,347, $61,200 and $379,808,
respectively.

12. Warrants:

  In connection with the issuance of the Series A Preferred Stock as described
in Note 10, the Company agreed to issue a warrant to purchase shares of Series
A Preferred Stock at $0.001 (par value) per share to an investor if certain
revenue milestones were not met by the Company. At the date the warrant was
offered, there was uncertainty as to whether the Company could achieve such
milestones. Therefore, the Company allocated the proceeds received from the
investor of $1,500,000 to the related Series A Preferred Stock shares and the
warrant based on their relative fair values, which were determined to be
$1,500,000 and $1,639,288, respectively. The amount of the proceeds allocated
to the Series A Preferred Stock shares and warrants was $716,723 and $783,277,
respectively. The warrant became fully vested, immediately exercisable and
nonforfeitable on July 30, 1999 when the Company did not meet the specified
milestones. The warrant was exercised in August 1999, and the Company issued
1,312,480 shares of Series A Preferred Stock.

  In connection with the execution of the Facility as described in Note 4, the
Company issued a warrant to purchase 80,000 shares of Series A Preferred Stock
at $1.25 per share to the lender. In June 1999, the warrant became fully
vested, exercisable and nonforfeitable as set forth in the Facility. The
warrant expires in June 2006. The fair value of the warrant was determined to
be approximately $113,000 which will be amortized over the life of the
equipment leases, or 36 months, as additional interest expense. As of September
30, 1999, the Company had recognized related interest expense of approximately
$9,000 and the warrant had not been exercised.

Convertible Series D Preferred Stock

  In January 2000, the Company issued 1,066,665 shares of Series D Preferred
Stock for $7,999,988, or $7.50 per share. In December 1999, the Company
received $1,100,000 in cash prior to the related issuance of the Series D
Preferred Stock. This advance receipt has been classified as a stock
subscription payable on the Consolidated Balance Sheet at December 31, 1999.
Additionally, in connection with the issuance of the Series D Preferred Stock
in January 1999, the Company expects to incur an estimated non-cash charge to
equity

value assigned to the BCF is limited to the proceeds from the Series D
Preferred Stock, the Company expects to record a BCF charge of $7,999,988. This
noncash equity charge will adversely impact the Company's net loss per share
attributable to common stockholders for the period ending March 31, 2000.

Convertible Notes Payable

  In January 2000, the Company issued convertible notes (the "Notes") in
exchange for $10,000,000. As defined in the agreement, the Notes are
convertible into equity securities of the Company upon the occurrence of
certain events, bear interest at 6% per annum and mature in January 2005, if
not converted. Thirty percent of the outstanding principal shall automatically
convert into equity securities of the Company upon the closing of the sale of
equity securities in which the Company receives gross proceeds of at least
$10,000,000 ("Qualified Financing"). The conversion rate shall be $17.00 per
equity security, or if the Qualified Financing is an IPO, the lesser of $17.00
or the IPO price per share. The Company has determined that the portion of the
Notes that are subject to automatic conversion, or $3,000,000, upon the closing
of a Qualified Financing have an associated BCF since the Notes are convertible
at a discount to the estimated deemed fair value of the common stock at the
date of issuance. As the BCF relates to the issuance of convertible debt, the
value assigned to the BCF, which cannot exceed the related proceeds, will be
charged to the Consolidated Statement of Operations as additional interest
expense when and if a Qualified Financing occurs (date at which contingency is
resolved). At the date of issuance, the total value assigned to the
automatically convertible portion was estimated to be $2,114,111. This non-cash
BCF charge will adversely impact the Company's net loss per share when and if a
Qualified Financing occurs.

Stock Option Grants

  From January 2000 to March 15, 2000, the Company has authorized stock option
grants to purchase 1,148,580 common shares at exercise prices ranging from
$1.00 to $12.00 per share. In connection with these authorized grants, the
Company expects to record an estimated deferred compensation amount of
approximately $23,300,000.

Stock Option Plan

  The Company's Year 2000 Stock Option Plan, which was authorized by the Board
in March 2000, will become effective upon the consummation of the IPO. In
addition, the Board authorized an additional 1,000,000 stock options to be
available for future grants.

Initial Public Offering and Unaudited Pro Forma Stockholders' Equity

  In March 2000, the Board of Directors authorized the filing of a registration
statement with the Securities and Exchange Commission that would permit the
Company to sell shares of the Company's common stock in an IPO. Unaudited pro
forma stockholders' equity reflects the conversion of each share of convertible
preferred stock into shares of common stock upon the completion of the IPO, and
the issuance of 1,066,665 shares of Series D Preferred Stock in January 2000
for proceeds of $7,999,988, proceeds allocable to the portion of the
convertible notes payable that will automatically convert into 176,470 shares
common stock and the estimated impact of the BCF of $7,999,988 and $2,114,111,
for the Series D Preferred Stock and convertible notes payable, respectively.

Company in the state of Delaware, and the increase in the number of authorized
shares, which will be effected prior to the closing of the IPO. The
accompanying consolidated financial statements have been presented to reflect
these events.

  The closing of this offering is a condition to the closing of the U.S.
offering, and the closing of the U.S. offering is a condition to the closing of
this offering.

  The underwriting agreement provides that the obligations of the several
underwriters to purchase the shares included in the offering are subject to
approval of legal matters by counsel as well as to other conditions. It also
states that if any shares are purchased by the underwriters pursuant to the
underwriting agreement, then all of the shares which the underwriters have
agreed to purchase pursuant to the underwriting agreement must be purchased.
The underwriters expect to deliver the shares on or about      , 2000.

  The underwriters propose to offer the shares directly to the public at the
public offering price set forth on the cover page of this prospectus, and to
specified selected dealers, who may include the underwriters, at the public
offering price less a selling concession not in excess of $     per share. The
underwriters may allow, and the selected dealers may reallow, a concession not
in excess of $     per share on sales to specified brokers and dealers. After
the offering, the representatives may change the offering price and other
selling terms. If all of the shares are not sold at the initial offering price,
the representatives may change the public offering price and the other selling
terms. The representatives have advised us that the underwriters do not intend
to confirm any sales to any accounts over which they exercise discretionary
authority that exceed 5% of the total number of shares of common stock offered
by them.

  We estimate that the total expenses of the offering, including registration,
filing and listing fees, printing fees and legal and accounting expenses but
excluding the underwriting discount will be approximately $     million.

  We have granted to the underwriters an option to purchase up to an additional
shares of common stock, exercisable solely to cover over-allotments, if any, at
the public offering price less the underwriting discount shown on the cover
page of this prospectus. The option may be exercised at any time until 30 days
after the date of the underwriting agreement. To the extent this option is
exercised, each underwriter will be committed, subject to various conditions,
to purchase a number of additional shares proportionate to its initial purchase
commitment as indicated in the preceding table and we will be obligated, under
the over-allotment option, to sell the shares to the underwriters.

  We, our officers, directors and some existing stockholders have agreed not to
do any of the following, whether any transaction described below is to be
settled by delivery of common stock or other securities, in cash or otherwise,
in each case without the prior written consent of Lehman Brothers, on behalf of
the underwriters, for a period of 180 days after the date of this prospectus:

  . offer, sell, pledge or otherwise dispose of, or enter into any
    transaction which is designed or could be expected to, result in the
    disposition by any person at any time in the future of, any shares of
    common stock or securities convertible into or exchangeable for common
    stock or substantially similar securities, other than the following:
    . the common stock sold under this prospectus,
    . the common stock to be issued concurrently with the closing of this
      offering upon the mandatory conversion of our outstanding preferred
      stock, and
    . shares of common stock we issue pursuant to employee benefit plans,
      qualified stock option plans or other employee compensation plans
      existing on the date of this prospectus or pursuant to currently
      outstanding options, warrants or rights.
  . sell or grant options, rights or warrants with respect to any shares of
    our common stock or securities convertible into or exchangeable for our
    common stock or substantially similar securities, other than the grant of
    options pursuant to option plans existing on the date hereof; and
  . enter into any swap or other derivatives transaction that transfers to
    another, in whole or in part, any of the economic benefits or risks or
    ownership of shares of common stock.

  Prior to the offering, there has been no public market for the common stock.
The initial public offering price for the common stock will be determined by
negotiation between oCen and the representatives. Among the factors to be
considered in such negotiations are:

  . prevailing market conditions;
  . the market values of publicly traded companies that we and the
    underwriters believe to be comparable to oCen;
  . the current state of oCen's development and its current financial
    condition;
  . the history of and prospects for oCen and the Asian IP telephony
    industry; and
  . the prospects for future revenues and earnings of oCen.

  We have applied for quotation of the common stock on the Nasdaq National
Market under the symbol OCCM.

  Fidelity Capital Markets, a division of National Financial Services
Corporation, is acting as an underwriter in this offering and will be
facilitating electronic distribution of information through the Internet,
intranet and other proprietary electronic technology.

  Until the distribution of the shares is completed, rules of the Securities
and Exchange Commission may limit the ability of the underwriters and selling
group members to bid for and purchase shares. As an exception

                                       75
<PAGE>

                                [ALTERNATE PAGE]

to these rules, the representatives are permitted to engage in transactions
that stabilize the price of the shares. These transactions may consist of bids
or purchases for the purposes of pegging, fixing or maintaining the price of
the shares.

  The underwriters may create a short position in the shares in connection with
the offering, which means that they may sell more shares than are set forth on
the cover page of this prospectus. If the underwriters create a short position,
then the representatives may reduce that short position by purchasing shares in
the open market. The representatives also may elect to reduce any short
position by exercising all or part of the over-allotment option.

  The representatives may impose a penalty bid on certain underwriters and
selling group members. This means that if the representatives purchase shares
in the open market to reduce the underwriters' short position or to stabilize
the price of the shares, they may reclaim the amount of the selling concession
from the underwriters and selling group members who sold those shares as part
of the offering.

  In general, purchases of a security for the purpose of stabilization or to
reduce a syndicate short position could cause the price of the security to be
higher than it might otherwise be in the absence of those purchases. The
imposition of a penalty bid might also have an effect on the price of a
security to the extent that it were to discourage resales of the security by
purchasers in an offering.

  Neither we nor any of the underwriters make any representation or prediction
as to the direction or magnitude of any effect that the transactions described
above may have on the price of the shares. In addition, neither we nor any of
the underwriters make any representation that the representatives will engage
in such transactions or that such transactions, once commenced, will not be
discontinued without notice.

  Offers and sales of shares being sold outside the United States have not been
registered under the Securities Act in reliance on Regulation S under the
Securities Act.

(where such an exemption is not available, offers shall be made only by a
registered dealer) in the relevant Canadian jurisdiction where any offer is

underwriting agreement, and liabilities incurred in connection with the
directed share program referred to below, and to contribute, under specified
circumstances, to payments that the underwriters may be required to make in
respect thereof.

  At our request, Lehman Brothers has reserved up to shares of common stock, or
% of the common stock offered by this prospectus, for sale pursuant to a
directed share program to officers, directors and employees, and their family
members, of oCen and its affiliates and friends of oCen's management. All of
the persons purchasing the reserved shares must commit to purchase no later
than the close of business on the day following the date of this prospectus.
The number of shares available for sale to the general public will be reduced
to the extent these persons purchase the reserved shares.

  Certain of the underwriters have provided from time to time, and expect to
provide in the future, financial advisory and investment banking services to us
and our affiliates, for which the underwriters have received and will receive
customary fees and commissions. ING Group and its affiliates own 16% of a
private equity fund which in turn owns approximately 20% of our existing share
capital. That fund's most recent investment in our company occurred in January
2000 when it acquired 400,184 additional shares of our capital stock. Jean
Salata, one of our directors, is the managing member of the general partner of
that fund. Lloyd Fischer, a director who owns approximately 1% of our existing
share capital, heads the Asian telecom investment banking team of ING Barings
and is a director of ING Barings Asia Limited.

and officers in terms sufficiently broad to permit such indemnification under
certain circumstances for liabilities (including reimbursement for expenses
incurred) arising under the Securities Act of 1933, as amended (the "Securities
Act"). As permitted by the Delaware General Corporation Law, the Registrant's
amended and restated certificate of incorporation includes a provision that
eliminates the personal liability of its directors for monetary damages for
breach of fiduciary duty as a director, except for liability (i) for any breach
of the director's duty of loyalty to the Registrant or its stockholders, (ii)
for acts or omissions not in good faith or that involve intentional misconduct
or a knowing violation of law, (iii) under section 174 of the Delaware General
Corporation Law (regarding unlawful dividends and stock purchases) or (iv) for
any transaction from which the director derived an improper personal benefit.
As permitted by the Delaware General Corporation Law, the bylaws of the
Registrant provide that (i) the Registrant is required to indemnify its
directors and officers to the fullest extent permitted by the Delaware General
Corporation Law, subject to certain very limited exceptions, (ii) the
Registrant may indemnify its other employees and agents as set forth in the
Delaware General Corporation Law, (iii) the Registrant is required to advance
expenses, as incurred, to its directors and executive officers in connection
with a legal proceeding to the fullest extent permitted by the Delaware General
Corporation Law, subject to certain very limited exceptions, and (iv) the
rights conferred in the bylaws are not exclusive. At present, there is no
pending litigation or proceeding involving a director, officer or employee of
the Registrant regarding which indemnification is sought, nor is the Registrant
aware of any threatened litigation that may result in claims for
indemnification. Reference is also made to Section   of the Underwriting
Agreement, which provides for the indemnification of officers, directors and
controlling persons of the Registrant against certain liabilities. The
indemnification provisions in the Registrant's amended and restated certificate
of incorporation and in its bylaws may be sufficiently broad to permit
indemnification of the Registrant's directors and executive officers for
liabilities arising under the Securities Act. Reference is made to the
following documents filed as exhibits to this registration statement regarding
relevant indemnification provisions described above and elsewhere herein:

  The Company has entered into indemnification agreements with each of the
Company's directors, a form of which is attached as an exhibit hereto and is
incorporated herein by reference.

  The Registrant may obtain insurance for the protection of its directors and
officers against any liability asserted against them in their official
capacities. The rights of indemnification described above are not exclusive of
any other rights of indemnification to which the persons indemnified may be
entitled under any bylaw, agreement, vote of stockholders or directors or
otherwise.

Item 15. Recent Sales of Unregistered Securities

  From our inception, we have funded losses and capital expenditures from cash
provided from financing activities. These activities included the private
placement of the following:

  .  Common Stock. Common stock sold to our founders for an aggregate
     principal amount of approximately $200,000 in October 1997.

  .  Convertible Notes. Convertible notes with an aggregate principal amount
     of approximately $280,000 sold to a group of private investors during
     fiscal years 1998 and 1999.

  .  Series A. Convertible preferred stock sold to Baring Private Equity
     Partners, under the BAPEF Investments IV fund, and private investors for
     an aggregate amount of approximately $2 million in November 1998.

  .  Series B. Convertible preferred stock sold to Excel-Foundation, a wholly
     owned subsidiary of New World Cyberbase, and Anderson Information
     Technology, for an aggregate amount of approximately $6.5 million in
     September 1999.

  .  Series C. Convertible preferred stock sold to existing stockholders,
     Lotus Asset Management under the Lotus Liberator Fund, and private
     investors for an aggregate amount of approximately $2.2 million in
     November 1999.

  .  Series D. Convertible preferred stock sold to existing stockholders for
     an aggregate amount of approximately $8 million in January 2000.

  .  Convertible Notes. Convertible notes with an aggregate principal amount
     of $10 million sold to a group of private investors in January 2000.

  The number of shares of common stock and convertible preferred stock below
reflects a 10,000 for one stock split in August 1998 and a 3-for-1 stock split
in April 1999.

  In October 1997, we issued an aggregate of 4,888,800 shares of common stock
for an aggregate purchase price of approximately $200,000 to our founders. We
also issued convertible notes with an aggregate principal amount of
approximately $280,000 during fiscal years 1998 and 1999. These notes bear
interest at the rate of 5.5% annually and expire in July 2001. In the event of
a qualified financing of at least $1 million in gross proceeds, the noteholders
have the option to convert these notes into equity securities at the same price
as the securities issued in the qualified financing. Approximately $230,000 of
the notes outstanding were converted into 186,234 shares of Series A preferred
stock in November 1998.

  In November 1998, we issued 1,600,023 shares of Series A convertible
preferred stock for $2 million, which included the conversion of some
promissory notes in November 1998. In connection with this offering, we issued
a warrant to purchase shares of Series A preferred stock if we did not meet
certain revenue milestones. The warrant became fully vested, immediately
exercisable and unable to be forfeited on July 31, 1999, when we did not meet
these milestones. The warrant was exercised in August 1999, and we issued
1,312,480 shares of Series A preferred stock.

  In connection with our credit facility, we issued to the lender a warrant to
purchase 80,000 shares of Series A convertible preferred stock at $1.25 per
share, which would be equivalent to    shares of common

                                      II-2
<PAGE>

stock upon consummation of this offering. In June 1999, the warrant became
fully vested, exercisable, and unable to be forfeited.

  In September 1999, we issued 3,403,141 shares of Series B convertible
preferred stock for $6.5 million to a subsidiary of New World Cyberbase and to
Anderson Information Technology.

  In November 1999, we issued 1,023,807 shares of Series C convertible
preferred stock for $2.2 million to Lotus Asset Management, a group of private
investors, and existing stockholders.

  In January 2000, we issued 1,066,665 shares of Series D convertible preferred
stock to existing stockholders for approximately $8 million.

  In January 2000, we issued $10 million in aggregate principal amount of
convertible notes bearing interest at 6% annually to a group of private
investors. If we receive gross proceeds of at least $10 million in another
round of financing, then 30% of the outstanding principal amount of each note
will convert into our capital stock of the Company with the rest of the balance
paid out by us. If we consummate an initial public offering prior to January
2005, receive gross proceeds of at least $10 million in another round of
financing, or default under the terms of the notes, then we, in our sole
discretion, can convert the entire outstanding amounts of the notes into our
capital stock.

B.Financial Statement Schedules

statements or notes thereto.

Item 17. Undertakings

  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the 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 of
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 to provide to the underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

  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.

                           OCEN COMMUNICATIONS, INC.


          The undersigned, ________________ and _______________, hereby certify
that:

          ONE:  They are the duly elected, qualified and acting President and
          ---
Secretary, respectively, of oCen Communications, Inc., a Delaware corporation.

          TWO:  The Certificate of Incorporation of said corporation was
          ---
originally filed in the Office of the Secretary of State of the State of
Delaware on ________, ____ and the Amended and Restated Certificate of
Incorporation of said corporation was originally filed in such office on
________, ____.

          THREE:  The Amended and Restated Certificate of Incorporation of said
          -----
corporation is amended and restated to read in its entirety as follows:

                                   ARTICLE I

          The name of this corporation is oCen Communications, Inc. (the
"Corporation").

                                  ARTICLE II


          The address of the Corporation's registered office in the State of
Delaware is 1013 Centre Road, City of Wilmington, County of New Castle, Delaware
19801.  The name of the Corporation's registered agent at such address is the
Corporation Service Company.

                                  ARTICLE III

          The nature of the business or purposes to be conducted or promoted is
to engage in any lawful act or activity for which corporations may be organized
under the General Corporation Law of the State of Delaware (the "GCL").

                                  ARTICLE IV

          The Corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock."  The total
number of shares that the Corporation is authorized to issue is
__________________ (__________).  _______________ (_________) shares shall be
Common Stock, par value $0.001 per share, and ______________ (_________) shares
shall be Preferred Stock, par value $0.001 per share.
<PAGE>

          The Preferred Stock may be issued from time to time in one or more
series, without further stockholder approval.  The Board of Directors of the
Corporation is hereby authorized to fix or alter the rights, preferences,
privileges and restrictions granted to or imposed upon each series of Preferred
Stock, and the number of shares constituting any such series and the designation
thereof, or of any of them.  The rights, privileges, preferences and
restrictions of any such additional series may be subordinated to, pari passu
                                                                   ----------
with (including, without limitation, inclusion in provisions with respect to
liquidation and acquisition preferences, redemption and/or approval of matters
by vote), or senior to any of those of any present or future class or series of
Preferred Stock or Common Stock.  The Board of Directors is also authorized to
increase or decrease the number of shares of any series prior or subsequent to
the issue 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 so decreased,
the shares constituting such decrease shall resume the status which they had
prior to the adoption of the resolution originally fixing the number of shares
of such series.

                                   ARTICLE V

          In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors is expressly authorized to make, repeal, alter,
amend and rescind any or all of the Bylaws of the Corporation.  In addition, the
Bylaws may be amended by the affirmative vote of holders of at least sixty-six
and two-thirds percent (66 2/3%) of the outstanding shares of voting stock of
the Corporation entitled to vote at an election of directors.

                                  ARTICLE VI

          The number of directors of the Corporation shall be determined by
resolution of the Board of Directors.

          Elections of directors need not be by written ballot unless the Bylaws
of the Corporation shall so provide.  Advance notice of stockholder nominations
for the election of directors and of any other business to be brought before any
meeting of the stockholders shall be given in the manner provided in the Bylaws
of this Corporation.

          At each annual meeting of stockholders, directors of the Corporation
shall be elected to hold office until the expiration of the term for which they
are elected, or until their successors have been duly elected and qualified;
except that if any such election shall not be so held, such election shall take
place at a stockholders' meeting called and held in accordance with the GCL.

          The directors of the Corporation shall be divided into three (3)
classes as nearly equal in size as is practicable, hereby designated Class I,
Class II and Class III.  For the purposes hereof, the initial Class I, Class II
and Class III directors shall be those directors so designated by a resolution
of the Board of Directors.  At the first annual meeting of stockholders
following the closing of the initial public offering of the Corporation's Common
Stock, the term of office of the Class I directors shall

                                       2
<PAGE>

expire and Class I directors shall be elected for a full term of three (3)
years. At the second annual meeting of stockholders following the closing of the
initial public offering of the Corporation's Common Stock, the term of office of
the Class II directors shall expire and Class II directors shall be elected for
a full term of three (3) years. At the third annual meeting of stockholders
following the initial public offering of the Corporation's Common Stock, the
term of office of the Class III directors shall expire and Class III directors
shall be elected for a full term of three (3) years. At each succeeding annual
meeting of stockholders, directors shall be elected for a full term of three (3)
years to succeed the directors of the class whose terms expire at such annual
meeting. If the number of directors is hereafter changed, each director then
serving as such shall nevertheless continue as a director of the Class of which
he is a member until the expiration of his current term and any newly created
directorships or decrease in directorships shall be so apportioned among the
classes as to make all classes as nearly equal in number as is practicable.

          Vacancies occurring on the Board of Directors for any reason may be
filled by vote of a majority of the remaining members of the Board of Directors,
even if less than a quorum, at any meeting of the Board of Directors.  A person
so elected by the Board of Directors to fill a vacancy 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 duly elected and
qualified.  A director may be removed from office by the affirmative vote of the
holders of 66 2/3% of the outstanding shares of voting stock of the Corporation
entitled to vote at an election of directors, provided that such removal is for
cause.

                                  ARTICLE VII

          Stockholders of the Corporation shall take action by meetings held
pursuant to this Amended and Restated Certificate of Incorporation and the
Bylaws and shall have no right to take any action by written consent without a
meeting.  Meetings of stockholders may be held within or without the State of
Delaware, as the Bylaws may provide.  Special meetings of the stockholders, for
any purpose or purposes, may only be called by the Board of Directors of the
Corporation.  The books of the Corporation may be kept (subject to any provision
contained in the statutes) outside the State of Delaware at such place or places
as may be designated from time to time by the Board of Directors or in the
Bylaws of the Corporation.

                                 ARTICLE VIII

          To the fullest extent permitted by applicable law, this Corporation is
authorized to provide indemnification of (and advancement of expenses to)
directors, officers, employees and agents (and any other persons to which
Delaware law permits this Corporation to provide indemnification) through Bylaw
provisions, agreements with such agents or other persons, vote of stockholders
or disinterested directors or otherwise, in excess of the indemnification and
advancement otherwise permitted by Section 145 of the GCL, subject only to
limits created by applicable Delaware law (statutory or non-statutory), with
respect to action for breach of duty to the Corporation, its stockholders, and
others.

          No director of the Corporation shall be personally liable to the
Corporation or any stockholder for monetary damages for breach of fiduciary duty
as a director, except for any matter in respect of which such director shall be
liable under Section 174 of the GCL or any amendment thereto or shall be liable
by reason that, in addition to any and all other requirements for such
liability, such director (1) shall have breached the director's duty or loyalty
to the

                                       3
<PAGE>

Corporation or its stockholders, (2) shall have acted in manner involving
intentional misconduct or a knowing violation of law or, in failing to act,
shall have acted in a manner involving intentional misconduct or a knowing
violation of law, or (3) shall have derived an improper personal benefit. If the
GCL is hereafter amended to authorize the further elimination or limitation of
the liability of a director, the liability of a director of the Corporation
shall be eliminated or limited to the fullest extent permitted by the GCL, as so
amended.

          Each person who was or is made a party or is threatened to be made a
party to or is in any way involved in any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (hereinafter a "proceeding"), including any appeal therefrom, by
reason of the fact that he or she, or a person of whom he or she is the legal
representative, is or was a director or officer of the Corporation or a direct
or indirect subsidiary of the Corporation, or is or was serving at the request
of the Corporation as a director or officer of another entity or enterprise, or
was a director or officer of a foreign or domestic corporation which was
predecessor corporation of the Corporation or of another entity or enterprise at
the request of such predecessor corporation, shall be indemnified and held
harmless by the Corporation, and the Corporation shall advance all expenses
incurred by any such person in defense of any such proceeding prior to its final
determination, to the fullest extent authorized by the GCL.  In any proceeding
against the Corporation to enforce these rights, such person shall be presumed
to be entitled to indemnification and the Corporation shall have the burden of
proving that such person has not met the standards of conduct for permissible
indemnification set forth in the GCL.  The rights to indemnification and
advancement of expenses conferred by this Article VIII shall be presumed to have
been relied upon by the directors and officers of the Corporation in serving or
continuing to serve the Corporation and shall be enforceable as contract rights.
Said rights shall not be exclusive of any other rights to which those seeking
indemnification may otherwise be entitled.  The Corporation may, upon written
demand presented by a director or officer of the Corporation or of a direct or
indirect subsidiary of the Corporation, or by a person serving at the request of
the Corporation as a director or officer of another entity or enterprise, enter
into contracts to provide such persons with specified rights to indemnification,
which contracts may confer rights and protections to the maximum extent
permitted by the GCL, as amended and in effect from time to time.

          If a claim under this Article VIII is not paid in full by the
Corporation within sixty (60) days after a written claim has been received by
the Corporation, the claimant may at any time thereafter bring suit against the
Corporation to recover the unpaid amount of the claim and, if successful in
whole or in part, the claimant shall be entitled to be paid also the expenses of
prosecuting such claim.  It shall be a defense to any such action (other than an
action brought to enforce the right to be advanced expenses incurred in
defending any proceeding prior to its final disposition where the required
undertaking, if any, has been tendered to the Corporation ) that the claimant
has not met the standards of conduct which make it permissible under the GCL for
the Corporation to indemnify the claimant for the amount claimed, but the
claimant shall be presumed to be entitled to indemnification and the Corporation
shall have the burden of proving that the claimant has not met the standards of
conduct for permissible indemnification set forth in the GCL.

                                       4
<PAGE>

          If the GCL is hereafter amended to permit the Corporation to provide
broader indemnification rights than said law permitted the Corporation to
provide prior to such amendment, the indemnification rights conferred by this
Article VIII shall be broadened to the fullest extent permitted by the GCL, as
so amended.

                                  ARTICLE IX

          The Corporation reserves the right to amend, alter, change or repeal
any provision contained in this Amended and Restated Certificate of
Incorporation, in the manner now or hereafter prescribed by statute, and all
rights conferred upon stockholders herein are granted subject to this
reservation.  Notwithstanding the foregoing, the provisions set forth in
Articles V, VI, VII, VIII and IX of this Amended and Restated Certificate of
Incorporation may not be repealed or amended in any respect without the
affirmative vote of holders at least 66-2/3% of the outstanding voting stock of
the Corporation entitled to vote at election of directors.

          ----

provisions of Sections 242 and 245 of the General Corporation Law of the State

          FIFTH:  The foregoing amendment and restatement was approved by the
          -----
holders of the requisite number of shares of the Corporation in accordance with
Section 228 of the General Corporation Law of the State of Delaware.

          IN WITNESS WHEREOF, the undersigned have executed this certificate on
     , 2000.

          Section 1.  The number of directors of this corporation that shall
          ----------
constitute the whole board shall be determined by resolution of the Board of
Directors; provided, however, that no decrease in the number of directors shall
have the effect of shortening the term of an incumbent director.  The Board of
Directors shall be classified, with respect to the time for which they severally
hold office, into three classes, as nearly equal in number as possible, as
determined by the Board of Directors, one class ("Class I") to hold office
initially for a term

                                       6

hold office initially for a term expiring at the annual meeting of stockholders
held in 2002 and another class ("Class III") to hold office initially for a term
expiring at the annual meeting of stockholders to be held in 2003, with the
members of each class to hold office until their successors are elected and
qualified. At each annual meeting of stockholders, the successors of the class
of directors whose term expires at that meeting shall be elected to hold office
for a term expiring at the annual meeting of stockholders held in the third year
following the year of their election.

          Section 2.  Vacancies and newly created directorships resulting from
          ----------
any increase in the authorized number of directors may be filled by a majority
of the directors then in office, though less than a quorum, or by a sole
remaining director, and the directors so chosen shall hold office until the next
annual meeting and until their successors are duly elected and qualified or
until earlier resignation or removal.  If there are no directors in office, then
an election of directors may be held in the manner provided by statute.

          Section 3.  The business of the corporation shall be managed by or
          ----------
under the direction of its Board of Directors which may exercise all such powers
of the corporation and do all such lawful acts and things as are not by statute
or by the certificate of incorporation or by these bylaws directed or required
to be exercised or done by the stockholders.

                      MEETINGS OF THE BOARD OF DIRECTORS

          ----------
meetings, both regular and special, either within or without the State of
Delaware.

          Section 5.  The first meeting of each newly elected Board of Directors
          ----------

stockholders at the annual meeting and no notice of such meeting shall be
necessary to the newly elected directors in order legally to

                                       7
<PAGE>

constitute the meeting, provided a quorum shall be present. In the event of the
failure of the stockholders to fix the time or place of such first meeting of
the newly elected Board of Directors, or in the event such meeting is not held
at the time and place so fixed by the stockholders, the meeting may be held at
such time and place as shall be specified in a notice given as hereinafter
provided for special meetings of the Board of Directors, or as shall be
specified in a written waiver signed by all of the directors.

          Section 6.  Regular meetings of the Board of Directors may be held
          ----------
without notice at such time and at such place as shall from time to time be
determined by the board.

          Section 7.  Special meetings of the board may be called by the
          ----------
president on two (2) days' notice to each director by mail or forty-eight (48)
hours notice to each director either personally, or by telephone, telegram or
facsimile; special meetings shall be called by the president or secretary in
like manner and on like notice on the written request of a majority of the Board
unless the Board consists of only one director, in which case special meetings
shall be called by the president or secretary in like manner and on like notice
on the written request of the sole director.  A written waiver of notice, signed
by the person entitled thereto, whether before or after the time of the meeting
stated therein, shall be deemed equivalent to notice.

          Section 8.  At all meetings of the board a majority of the directors
          ----------
shall constitute a quorum for the transaction of business and the act of a
majority of the directors present at any meeting at which there is a quorum
shall be the act of the Board of Directors, except as may be otherwise
specifically provided by statute or by the certificate of incorporation.  If a
quorum shall not be present at any meeting of the Board of Directors, the
directors present thereat may adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present.

          Section 9.  Unless otherwise restricted by the certificate of
          ----------
incorporation of these bylaws, any action required or permitted to be taken at
any meeting of the Board of Directors or of any committee thereof may be taken
without a meeting, if all members of the board or committee, as the case may be,

incorporation or these bylaws, members of the Board of Directors, or any
committee designated by the Board of Directors, may participate in a meeting of
the Board of Directors, or any committee, by means of conference telephone or
similar communications equipment by means of which all persons participating in
the meeting can hear each other, and such participation in a meeting shall
constitute presence in person at the meeting.

                            COMMITTEES OF DIRECTORS

          Section 11.  The Board of Directors may, by resolution passed by a
          -----------
majority of the whole board, designate one (1) or more committees, each
committee to consist of one (1) or more of the directors of the corporation.
The board may designate one (1) or more directors as alternate members of any
committee, who may replace any absent or disqualified member at any meeting of
the committee.

          In the absence of disqualification of a member of a committee, the
member or members thereof present at any meeting and not disqualified from
voting, whether or not he or they constitute a quorum, may unanimously appoint
another member of the Board of Directors to act at the meeting in the place of
any such absent or disqualified member.

          Any such committee, to the extent provided in the resolution of the
Board of Directors, shall have and may exercise all the powers and authority of
the Board of Directors in

                                       9
<PAGE>

the management of the business and affairs of the corporation, and may authorize
the seal of the corporation to be affixed to all papers that may require it; but

certificate of incorporation, adopting an agreement of merger or consolidation,
recommending to the stockholders the sale, lease or exchange of all or
substantially all of the corporation's property and assets, recommending to the
stockholders a dissolution of the corporation or a revocation of a dissolution,
or amending the bylaws of the corporation; and, unless the resolution or the
certificate of incorporation expressly so provide, no such committee shall have
the power or authority to declare a dividend or to authorize the issuance of
stock. Such committee or committees shall have such name or names as may be
determined from time to time by resolution adopted by the Board of Directors.

          Section 12.  Each committee shall keep regular minutes of its meetings
          -----------
and report the same to the Board of Directors when required.

                           COMPENSATION OF DIRECTORS

          Section 13.  Unless otherwise restricted by the certificate of
          -----------
incorporation or these bylaws, the Board of Directors shall have the authority
to fix the compensation of directors.  The directors may be paid their expenses,
if any, of attendance at each meeting of the Board of Directors and may be paid
a fixed sum for attendance at each meeting of the Board of Directors or a stated
salary as director.  No such payment shall preclude any director from serving
the corporation in any other capacity and receiving compensation therefor.
Members of special or standing committees may be allowed like compensation for
attending committee meetings.

                             REMOVAL OF DIRECTORS

          Section 14.  Unless otherwise restricted by the certificate of

          ----------
certificate of incorporation or of these bylaws, notice is required to be given
to any director or stockholder, it shall not be construed to mean personal

                                       19
<PAGE>

          Section 6.  The corporation shall, to the fullest extent authorized
          ----------
under the laws of the State of Delaware, as those laws may be amended and
supplemented from time to time, indemnify any director made, or threatened to be
made, a party to an action or proceeding, whether criminal, civil,
administrative or investigative, by reason of being a director of the
corporation or a predecessor corporation or, at the corporation's request, a
director or officer of another corporation, provided, however, that the
corporation shall indemnify any such agent in connection with a proceeding
initiated by such agent only if such proceeding was authorized by the Board of
Directors of the corporation.  The indemnification provided for in this Section
6 shall: (i) not be deemed exclusive of any other rights to which those
indemnified may be entitled under any bylaw, agreement or vote of stockholders
or disinterested directors or otherwise, both as to action in their official
capacities and as to action in another capacity while holding such office, (ii)
continue as to a person who has ceased to be a director, and (iii) inure to the
benefit of the heirs, executors and administrators of such a person.  The
corporation's obligation to provide indemnification under this Section 6 shall
be offset to the extent of any other source of indemnification or any otherwise
applicable insurance coverage under a policy maintained by the corporation or
any other person.

          Expenses incurred by a director of the corporation in defending a
civil or criminal action, suit or proceeding by reason of the fact that he is or
was a director of the corporation (or was serving at the corporation's request
as a director or officer of another corporation) shall be paid by the
corporation in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of such director to
repay such amount if it shall ultimately be determined that he is not entitled
to be indemnified by the corporation as authorized by relevant sections of the
General Corporation Law of Delaware.  Notwithstanding

                                       20
<PAGE>

the foregoing, the corporation shall not be required to advance such expenses to
an agent who is a party to an action, suit or proceeding brought by the
corporation and approved by a majority of the Board of Directors of the
corporation which alleges willful misappropriation of corporate assets by such
agent, disclosure of confidential information in violation of such agent's
fiduciary or contractual obligations to the corporation or any other willful and
deliberate breach in bad faith of such agent's duty to the corporation or its
stockholders.

          The foregoing provisions of this Section 6 shall be deemed to be a
contract between the corporation and each director who serves in such capacity
at any time while this bylaw is in effect, and any repeal or modification
thereof shall not affect any rights or obligations then existing with respect to
any state of facts then or theretofore existing or any action, suit or
proceeding theretofore or thereafter brought based in whole or in part upon any
such state of facts.

          The Board of Directors in its discretion shall have power on behalf of
the corporation to indemnify any person, other than a director, made a party to
any action, suit or proceeding by reason of the fact that he, his testator or
intestate, is or was an officer or employee of the corporation.

          To assure indemnification under this Section 6 of all directors,
officers and employees who are determined by the corporation or otherwise to be
or to have been "fiduciaries" of any employee benefit plan of the corporation
which may exist from time to time, Section 145 of the General Corporation Law of
Delaware shall, for the purposes of this Section 6, be interpreted as follows:
an "other enterprise" shall be deemed to include such an employee benefit plan,
including without limitation, any plan of the corporation which is governed by
the Act of Congress entitled "Employee Retirement Income Security Act of 1974,"
as amended from

                                       21
<PAGE>

time to time; the corporation shall be deemed to have requested a person to
serve an employee benefit plan where the performance by such person of his
duties to the corporation also imposes duties on, or otherwise involves services
by, such person to the plan or participants or beneficiaries of the plan; excise
taxes assessed on a person with respect to an employee benefit plan pursuant to
such Act of Congress shall be deemed "fines."

                                 ARTICLE VIII

                                  AMENDMENTS

          Section 1.  These bylaws may be altered, amended or repealed or new
          ----------
bylaws may be adopted by the affirmative vote of holders of at least 66-2/3%
vote of the outstanding voting stock of the corporation.  These bylaws may also
be altered, amended or repealed or new bylaws may be adopted by the Board of
Directors, when such power is conferred upon the Board of Directors by the
certificate of incorporation.  The foregoing may occur at any regular meeting of
the stockholders or of the Board of Directors or at any special meeting of the
stockholders or of the Board of Directors if notice of such alteration,
amendment, repeal or adoption of new bylaws be contained in the notice of such
special meeting.  If the power to adopt, amend or repeal bylaws is conferred
upon the Board of Directors by the certificate of incorporation it shall not
divest or limit the power of the stockholders to adopt, amend or repeal bylaws.

               This 1998 Stock Option/Stock Issuance Plan is intended to promote
the interests of oCen Communications, Inc., a California, by providing eligible
persons in the Corporation's employ or service with the opportunity to acquire a
proprietary interest, or otherwise increase their proprietary interest, in the
Corporation as an incentive for them to continue in such employ or service.

               Capitalized terms herein shall have the meanings assigned to such
terms in the attached Appendix.

          II.  STRUCTURE OF THE PLAN

               A. The Plan shall be divided into two (2) separate equity
programs:

                         (i)  the Option Grant Program under which eligible
     persons may, at the discretion of the Plan Administrator, be granted
     options to purchase shares of Common Stock, and

                         (ii) the Stock Issuance Program under which eligible
     persons may, at the discretion of the Plan Administrator, be issued shares
     of Common Stock directly, either through the immediate purchase of such
     shares or as a bonus for services rendered the Corporation (or any Parent
     or Subsidiary).

               B. The provisions of Articles One and Four shall apply to both
equity programs under the Plan and shall accordingly govern the interests of all
persons under the Plan.

     III.  ADMINISTRATION OF THE PLAN

administrative functions otherwise exercisable by the Board may be delegated to
the Committee.  Members of the Committee shall serve for such period of time as

time.  The Board may also at any time terminate the functions of the Committee
and reassume all powers and authority previously delegated to the Committee.
<PAGE>

               B.  The Plan Administrator shall have full power and authority
(subject to the provisions of the Plan) to establish such rules and regulations
as it may deem appropriate for proper administration of the Plan and to make
such determinations under, and issue such interpretations of, the Plan and any
outstanding options or stock issuances thereunder as it may deem necessary or
advisable. Decisions of the Plan Administrator shall be final and binding on all
parties who have an interest in the Plan or any option or stock issuance
thereunder.

          IV.  ELIGIBILITY

               A.  The persons eligible to participate in the Plan are as

                         (ii)  non-employee members of the Board or the non-
     employee members of the board of directors of any Parent or Subsidiary, and

                         (iii) consultants and other independent advisors who
     provide services to the Corporation (or any Parent or Subsidiary).

               B.  The Plan Administrator shall have full authority to
determine, (i) with respect to the grants made under the Option Grant Program,
which eligible persons are to receive the option grants, the time or times when
those grants are to be made, the number of shares to be covered by each such
grant, the status of the granted option as either an Incentive Option or a Non-
Statutory Option, the time or times when each option is to become exercisable,
the vesting schedule (if any) applicable to the option shares and the maximum
term for which the option is to remain outstanding, and (ii) with respect to
stock issuances made under the Stock Issuance Program, which eligible persons
are to receive such stock issuances, the time or times when those issuances are
to be made, the number of shares to be issued to each Participant, the vesting
schedule (if any) applicable to the issued shares and the consideration to be
paid by the Participant for such shares.

               C.  The Plan Administrator shall have the absolute discretion
either to grant options in accordance with the Option Grant Program or to effect
stock issuances in accordance with the Stock Issuance Program.

          V.   STOCK SUBJECT TO THE PLAN

               A.  The stock issuable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock. The maximum number of shares
of Common Stock which may be issued over the term of the Plan shall not exceed
2,611,200/1/ shares.

               B.  Shares of Common Stock subject to outstanding options shall
be available for subsequent issuance under the Plan to the extent (i) the
options expire or terminate

______________________

     /1/ Adjusted for 3-1 forward split of the Common Stock, as approved by the
Board of Directors on January 8, 1999.

for any reason prior to exercise in full or (ii) the options are cancelled in
accordance with the cancellation-regrant provisions of Article Two. Unvested
shares issued under the Plan and subsequently repurchased by the Corporation, at
the option exercise or direct issue price paid per share, pursuant to the
Corporation's repurchase rights under the Plan shall be added back to the number
of shares of Common Stock reserved for issuance under the Plan and shall
accordingly be available for reissuance through one or more subsequent option
grants or direct stock issuances under the Plan.

               C.  Should any change be made to the Common Stock by reason of
any stock split, stock dividend, recapitalization, combination of shares,
exchange of shares or other change affecting the outstanding Common Stock as a
class without the Corporation's receipt of consideration, appropriate
adjustments shall be made to (i) the maximum number and/or class of securities
issuable under the Plan and (ii) the number and/or class of securities and the
exercise price per share in effect under each outstanding option in order to
prevent the dilution or enlargement of benefits thereunder. The adjustments
determined by the Plan Administrator shall be final, binding and conclusive. In
no event shall any such adjustments be made in connection with the conversion of
one or more outstanding shares of the Corporation's preferred stock into shares
of Common Stock.

                             OPTION GRANT PROGRAM

          I.   OPTION TERMS

               Each option shall be evidenced by one or more documents in the
form approved by the Plan Administrator; provided, however, that each such
document shall comply with the terms specified below. Each document evidencing
an Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

               A.   Exercise Price.
                    --------------

                    1.  The exercise price per share shall be fixed by the Plan
     Administrator in accordance with the following provisions:

                         (i)  The exercise price per share shall not be less
     than eighty-five percent (85%) of the Fair Market Value per share of Common
     Stock on the option grant date.

                         (ii) If the person to whom the option is granted is a
     10% Shareholder, then the exercise price per share shall not be less than
     one hundred ten percent (110%) of the Fair Market Value per share of Common
     Stock on the option grant date.

                    2.   The exercise price shall become immediately due upon
exercise of the option and shall, subject to the provisions of Section I of
Article Four and the documents evidencing the option, be payable in cash or
check made payable to the Corporation. Should the Common Stock be registered
under Section 12 of the 1934 Act at the time the option is exercised, then the
exercise price may also be paid as follows:

                         (i)  in shares of Common Stock held for the requisite
     period necessary to avoid a charge to the Corporation's earnings for
     financial reporting purposes and valued at Fair Market Value on the
     Exercise Date, or

                         (ii) to the extent the option is exercised for vested
     shares, through a special sale and remittance procedure pursuant to which
     the Optionee shall concurrently provide irrevocable instructions (A) to a
     Corporation-designated brokerage firm to effect the immediate sale of the
     purchased shares and remit to the Corporation, out of the sale proceeds
     available on the settlement date, sufficient funds to cover the aggregate
     exercise price payable for the purchased shares plus all applicable
     Federal, state and local income and employment taxes required to be
     withheld by the Corporation by

                                      4.
<PAGE>

     reason of such exercise and (B) to the Corporation to deliver the
     certificates for the purchased shares directly to such brokerage firm in
     order to complete the sale.

               Except to the extent such sale and remittance procedure is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

               B.   Exercise and Term of Options. Each option shall be
                    ----------------------------
exercisable at such time or times, during such period and for such number of
shares as shall be determined by the Plan Administrator and set forth in the
documents evidencing the option grant. However, no option shall have a term in
excess of ten (10) years measured from the option grant date.

               C.   Effect of Termination of Service.
                    --------------------------------

                    1.   The following provisions shall govern the exercise of
any options held by the Optionee at the time of cessation of Service or death:

                         (i)   Should the Optionee cease to remain in Service
     for any reason other than death, Disability or Misconduct, then the period
     during which each such outstanding option may be exercised shall be limited
     to the three (3) month period measured from the date of such cessation of
     Service.

                         (ii)  Should Optionee's Service terminate by reason of
     Disability, then period during which each such outstanding option may be
     exercised shall be limited to the twelve (12)-month period measured from
     the date of such cessation of Service.

                         (iii) If the Optionee dies while holding an outstanding
option, then the personal representative of his or her estate or the person or
persons to whom the option is transferred pursuant to the Optionee's will or the
laws of inheritance shall have a twelve (12)-month period following the date of
the Optionee's death to exercise such option.

                         (iv)  Under no circumstances, however, shall any such
     option be exercisable after the specified expiration of the option term.

                         (v)   During the applicable post-Service exercise
     period, the option may not be exercised in the aggregate for more than the
     number of vested shares for which the option is exercisable on the date of
     the Optionee's cessation of Service. Upon the expiration of the applicable
     exercise period or (if earlier) upon the expiration of the option term, the
     option shall terminate and cease to be outstanding for any vested shares
     for which the option has not been exercised. However, the option shall,
     immediately upon the Optionee's cessation of Service, terminate and cease
     to be outstanding with respect to any and all option shares for which the
     option is not otherwise at the time exercisable or in which the Optionee is
     not otherwise at that time vested.

                                      5.
<PAGE>

                         (vi)  Should Optionee's Service be terminated for
     Misconduct, then all outstanding options held by the Optionee shall
     terminate immediately and cease to remain outstanding.

                    2.   The Plan Administrator shall have the discretion,
     exercisable either at the time an option is granted or at any time while
     the option remains outstanding, to:

                         (i)   extend the period of time for which the option is
     to remain exercisable following Optionee's cessation of Service or death
     from the limited period otherwise in effect for that option to such greater
     period of time as the Plan Administrator shall deem appropriate, but in no
     event beyond the expiration of the option term, and/or

                         (ii)  permit the option to be exercised, during the
     applicable post-Service exercise period, not only with respect to the
     number of vested shares of Common Stock for which such option is
     exercisable at the time of the Optionee's cessation of Service but also
     with respect to one or more additional installments in which the Optionee
     would have vested under the option had the Optionee continued in Service.

               D.   Shareholder Rights. The holder of an option shall have no
                    ------------------
shareholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become the
holder of record of the purchased shares.

               E.   Unvested Shares. The Plan Administrator shall have the
                    ---------------
discretion to grant options which are exercisable for unvested shares of Common
Stock. Should the Optionee cease Service while holding such unvested shares, the
Corporation shall have the right to repurchase, at the exercise price paid per
share, any or all of those unvested shares. The terms upon which such repurchase
right shall be exercisable (including the period and procedure for exercise and
the appropriate vesting schedule for the purchased shares) shall be established
by the Plan Administrator and set forth in the document evidencing such
repurchase right. The Plan Administrator may not impose a vesting schedule upon
the option grant or any shares of Common Stock subject to that option which is
more restrictive than twenty percent (20%) per year vesting, with the initial
vesting to occur not later than one (1) year after the option grant date.
However, such limitation shall not be applicable to any option grants made to
individuals who are officers of the Corporation, non-employee Board members or
independent consultants.

               F.  First Refusal Rights. Until such time as the Common Stock is
                   --------------------
first registered under Section 12 of the 1934 Act, the Corporation shall have
the right of first refusal with respect to any proposed disposition by the
Optionee (or any successor in interest) of any shares of Common Stock issued
under the Plan. Such right of first refusal shall be exercisable in accordance
with the terms established by the Plan Administrator and set forth in the
document evidencing such right.

                                      6.
<PAGE>

               G.   Limited Transferability of Options. During the lifetime of
                    ----------------------------------
the Optionee, Incentive Options shall be exercisable only by the Optionee and
shall not be assignable or transferable other than by will or by the laws of
descent and distribution following the Optionee's death.

               H.   Withholding. The Corporation's obligation to deliver shares
                    -----------
of Common Stock upon the exercise of any options granted under the Plan shall be
subject to the satisfaction of all applicable Federal, state and local income
and employment tax withholding requirements.

          II.  INCENTIVE OPTIONS

               The terms specified below shall be applicable to all Incentive
Options.  Except as modified by the provisions of this Section II, all the
provisions of the Plan shall be applicable to Incentive Options.  Options which
are specifically designated as Non-Statutory Options shall not be subject to the
terms of this Section II.

               A.   Eligibility. Incentive Options may only be granted to
                    -----------
Employees.

               B.   Exercise Price. The exercise price per share shall not be
                    --------------
less than one hundred percent (100%) of the Fair Market Value per share of
Common Stock on the option grant date.

               C.   Dollar Limitation. The aggregate Fair Market Value of the
                    -----------------
shares of Common Stock (determined as of the respective date or dates of grant)
for which one or more options granted to any Employee under the Plan (or any
other option plan of the Corporation or any Parent or Subsidiary) may for the
first time become exercisable as Incentive Options during any one (1) calendar
year shall not exceed the sum of One Hundred Thousand Dollars ($100,000). To the
extent the Employee holds two (2) or more such options which become exercisable
for the first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

               D.   10% Shareholder. If any Employee to whom an Incentive Option
                    ---------------
is granted is a 10% Shareholder, then the option term shall not exceed five (5)
years measured from the option grant date.

                                      7.
<PAGE>

          III. CORPORATE TRANSACTION

               A.  The shares subject to each option outstanding under the Plan
at the time of a Corporate Transaction shall automatically vest in full so that
each such option shall, immediately prior to the effective date of the Corporate
Transaction, become fully exercisable for all of the shares of Common Stock at
the time subject to that option and may be exercised for any or all of those
shares as fully-vested shares of Common Stock. However, the shares subject to an
outstanding option shall not vest on such an accelerated basis if and to the
extent: (i) such option is assumed by the successor corporation (or parent
thereof) in the Corporate Transaction and the Corporation's repurchase rights
with respect to the unvested option shares are concurrently assigned to such
successor corporation (or parent thereof) or (ii) such option is to be replaced
with a cash incentive program of the successor corporation which preserves the
spread existing on the unvested option shares at the time of the Corporate
Transaction and provides for subsequent payout in accordance with the same
vesting schedule applicable to those unvested option shares or (iii) the
acceleration of such option is subject to other limitations imposed by the Plan
Administrator at the time of the option grant.

               B.  All outstanding repurchase rights shall also terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in the event of any Corporate Transaction,
except to the extent: (i) those repurchase rights are assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction or
(ii) such accelerated vesting is precluded by other limitations imposed by the
Plan Administrator at the time the repurchase right is issued.

               C.  Immediately following the consummation of the Corporate
Transaction, all outstanding options shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

               D.  Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction, had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to (i) the number and class of
securities available for issuance under the Plan following the consummation of
such Corporate Transaction and (ii) the exercise price payable per share under
each outstanding option, provided the aggregate exercise price payable for such
securities shall remain the same.

               E.  The Plan Administrator shall have the discretion, exercisable
either at the time the option is granted or at any time while the option remains
outstanding, to provide for the automatic acceleration (in whole or in part) of
one or more outstanding options (and the immediate termination of the
Corporation's repurchase rights with respect to the shares subject to those
options) upon the occurrence of a Corporate Transaction, whether or not those
options are to be assumed in the Corporate Transaction.

                                      8.
<PAGE>

               F.  The Plan Administrator shall also have full power and
authority, exercisable either at the time the option is granted or at any time
while the option remains outstanding, to structure such option so that the
shares subject to that option will automatically vest on an accelerated basis
should the Optionee's Service terminate by reason of an Involuntary Termination
within a designated period (not to exceed eighteen (18) months) following the
effective date of any Corporate Transaction in which the option is assumed and
the repurchase rights applicable to those shares do not otherwise terminate. Any
option so accelerated shall remain exercisable for the fully-vested option
shares until the earlier of (i) the expiration of the option term or (ii) the
expiration of the one (1)-year period measured from the effective date of the
Involuntary Termination. In addition, the Plan Administrator may provide that
one or more of the Corporation's outstanding repurchase rights with respect to
shares held by the Optionee at the time of such Involuntary Termination shall
immediately terminate on an accelerated basis, and the shares subject to those
terminated rights shall accordingly vest at that time.

               G.  The portion of any Incentive Option accelerated in connection
with a Corporate Transaction shall remain exercisable as an Incentive Option
only to the extent the applicable One Hundred Thousand Dollar limitation is not
exceeded. To the extent such dollar limitation is exceeded, the accelerated
portion of such option shall be exercisable as a Non-Statutory Option under the
Federal tax laws.

               H.  The grant of options under the Plan shall in no way affect
the right of the Corporation to adjust, reclassify, reorganize or otherwise
change its capital or business structure or to merge, consolidate, dissolve,
liquidate or sell or transfer all or any part of its business or assets.

          IV.  CANCELLATION AND REGRANT OF OPTIONS

               The Plan Administrator shall have the authority to effect, at any
time and from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Plan and to grant in
substitution therefor new options covering the same or different number of
shares of Common Stock but with an exercise price per share based on the Fair
Market Value per share of Common Stock on the new option grant date.

                            STOCK ISSUANCE PROGRAM


          I.   STOCK ISSUANCE TERMS

               Shares of Common Stock may be issued under the Stock Issuance
Program through direct and immediate issuances without any intervening option
grants. Each such stock issuance shall be evidenced by a Stock Issuance
Agreement which complies with the terms specified below.

               A.   Purchase Price.
                    --------------

                    1.  The purchase price per share shall be fixed by the Plan
     Administrator but shall not be less than eighty-five percent (85%) of the
     Fair Market Value per share of Common Stock on the issue date. However, the
     purchase price per share of Common Stock issued to a 10% Shareholder shall
     not be less than one hundred and ten percent (110%) of such Fair Market
     Value.

                    2.  Subject to the provisions of Section I of Article Four,
     shares of Common Stock may be issued under the Stock Issuance Program for
     any of the following items of consideration which the Plan Administrator
     may deem appropriate in each individual instance:

                        (i)  cash or check made payable to the Corporation, or

                        (ii) past services rendered to the Corporation (or any
     Parent or Subsidiary).

               B.   Vesting Provisions.
                    ------------------

                    1.  Shares of Common Stock issued under the Stock Issuance
Program may, in the discretion of the Plan Administrator, be fully and
immediately vested upon issuance or may vest in one or more installments over
the Participant's period of Service or upon attainment of specified performance
objectives. However, the Plan Administrator may not impose a vesting schedule
upon any stock issuance effected under the Stock Issuance Program which is more
restrictive than twenty percent (20%) per year vesting, with initial vesting to
occur not later than one (1) year after the issuance date. Such limitation shall
not apply to any Common Stock issuances made to the officers of the Corporation,
non-employee Board members or independent consultants.

                                      10.
<PAGE>

          2.  Any new, substituted or additional securities or other property
(including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to the Participant's
unvested shares of Common Stock by reason of any stock dividend, stock split,
recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's
receipt of consideration shall be issued subject to (i) the same vesting
requirements applicable to the Participant's unvested shares of Common Stock and
(ii) such escrow arrangements as the Plan Administrator shall deem appropriate.

          3.  The Participant shall have full shareholder rights with respect to
any shares of Common Stock issued to the Participant under the Stock Issuance
Program, whether or not the Participant's interest in those shares is vested.
Accordingly, the Participant shall have the right to vote such shares and to
receive any regular cash dividends paid on such shares.

          4.  Should the Participant cease to remain in Service while holding
one or more unvested shares of Common Stock issued under the Stock Issuance
Program or should the performance objectives not be attained with respect to one
or more such unvested shares of Common Stock, then those shares shall be
immediately surrendered to the Corporation for cancellation, and the Participant
shall have no further shareholder rights with respect to those shares. To the
extent the surrendered shares were previously issued to the Participant for
consideration paid in cash or cash equivalent (including the Participant's
purchase-money indebtedness), the Corporation shall repay to the Participant the
cash consideration paid for the surrendered shares and shall cancel the unpaid
principal balance of any outstanding purchase-money note of the Participant
attributable to such surrendered shares.

          5.  The Plan Administrator may in its discretion waive the surrender
and cancellation of one or more unvested shares of Common Stock (or other assets
attributable thereto) which would otherwise occur upon the non-completion of the
vesting schedule applicable to such shares. Such waiver shall result in the
immediate vesting of the Participant's interest in the shares of Common Stock as
to which the waiver applies. Such waiver may be effected at any time, whether
before or after the Participant's cessation of Service or the attainment or non-
attainment of the applicable performance objectives.

          6.  First Refusal Rights. Until such time as the Common Stock is first
registered under Section 12 of the 1934 Act, the Corporation shall have the
right of first refusal with respect to any proposed disposition by the
Participant (or any successor in interest) of any shares of Common Stock issued
under the Stock Issuance Program. Such right of first refusal shall be
exercisable in accordance with the terms established by the Plan Administrator
and set forth in the document evidencing such right.

                                      11.
<PAGE>

          II.  CORPORATE TRANSACTION

               A.  Upon the occurrence of a Corporate Transaction, all
outstanding repurchase rights under the Stock Issuance Program shall terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, except to the extent: (i) those repurchase
rights are assigned to the successor corporation (or parent thereof) in
connection with such Corporate Transaction or (ii) such accelerated vesting is
precluded by other limitations imposed by the Plan Administrator at the time the
repurchase right is issued.

               B.  The Plan Administrator shall have the discretionary
authority, exercisable either at the time the unvested shares are issued or any
time while the Corporation's repurchase rights with respect to those shares
remain outstanding, to provide that those rights shall automatically terminate
on an accelerated basis, and the shares of Common Stock subject to those
terminated rights shall immediately vest, in the event the Participant's Service
should subsequently terminate by reason of an Involuntary Termination within a
designated period (not to exceed eighteen (18) months) following the effective
date of any Corporate Transaction in which those repurchase rights are assigned
to the successor corporation (or parent thereof).

          III. SHARE ESCROW/LEGENDS

               Unvested shares may, in the Plan Administrator's discretion, be
held in escrow by the Corporation until the Participant's interest in such
shares vests or may be issued directly to the Participant with restrictive
legends on the certificates evidencing those unvested shares.

                                      12.

                                 MISCELLANEOUS

          I.   FINANCING

               The Plan Administrator may permit any Optionee or Participant to
pay the option exercise price or the purchase price for shares issued to such
person under the Plan by delivering a full-recourse, interest-bearing promissory
note payable in one or more installments and secured by the purchased shares.
However, any promissory note delivered by a consultant must be secured by
collateral in addition to the purchased shares of Common Stock. In no event
shall the maximum credit available to the Optionee or Participant exceed the sum
of (i) the aggregate option exercise price or purchase price payable for the
purchased shares plus (ii) any Federal, state and local income and employment
tax liability incurred by the Optionee or the Participant in connection with the

          II.  EFFECTIVE DATE AND TERM OF PLAN

               A.  The Plan became effective upon its adoption by the Board on
August 10, 1998, but no option granted under the Plan may be exercised, and no
shares shall be issued under the Plan, until the Plan is approved by the
Corporation's shareholders. If such shareholder approval is not obtained within
twelve (12) months after the date of the Board's adoption of the Plan, then all
options previously granted under the Plan shall terminate and cease to be
outstanding, and no further options shall be granted and no shares shall be
issued under the Plan. Subject to such limitation, the Plan Administrator may
grant options and issue shares under the Plan at any time after the effective
date of the Plan and before the date fixed herein for termination of the Plan.

               B.  The Plan shall terminate upon the earliest of (i) August 10,
2008, (ii) the date on which all shares available for issuance under the Plan
shall have been issued as vested shares or (iii) the termination of all
outstanding options in connection with a Corporate Transaction. All options and
unvested stock issuances outstanding at that time under the Plan shall continue
to have full force and effect in accordance with the provisions of the documents
evidencing such options or issuances.

          III. AMENDMENT OF THE PLAN

               A.  The Board shall have complete and exclusive power and
authority to amend or modify the Plan in any or all respects. However, no such
amendment or modification shall adversely affect the rights and obligations with
respect to options or unvested stock issuances at the time outstanding under the
Plan unless the Optionee or the Participant consents to such amendment or
modification. In addition, certain amendments may require shareholder approval
pursuant to applicable laws and regulations.

                                      13.
<PAGE>

               B.  Options may be granted under the Option Grant Program and
shares may be issued under the Stock Issuance Program which are in each instance
in excess of the number of shares of Common Stock then available for issuance
under the Plan, provided any excess shares actually issued under those programs
shall be held in escrow until there is obtained shareholder approval of an
amendment sufficiently increasing the number of shares of Common Stock available
for issuance under the Plan. If such shareholder approval is not obtained within
twelve (12) months after the date the first such excess issuances are made, then
(i) any unexercised options granted on the basis of such excess shares shall
terminate and cease to be outstanding and (ii) the Corporation shall promptly
refund to the Optionees and the Participants the exercise or purchase price paid
for any excess shares issued under the Plan and held in escrow, together with
interest (at the applicable Short Term Federal Rate) for the period the shares
were held in escrow, and such shares shall thereupon be automatically cancelled
and cease to be outstanding.

          IV.  USE OF PROCEEDS

               Any cash proceeds received by the Corporation from the sale of
shares of Common Stock under the Plan shall be used for general corporate
purposes.

          V.   WITHHOLDING

               The Corporation's obligation to deliver shares of Common Stock
upon the exercise of any options or upon the issuance or vesting of any shares
issued under the Plan shall be subject to the satisfaction of all applicable
Federal, state and local income and employment tax withholding requirements.

          VI.  REGULATORY APPROVALS

               The implementation of the Plan, the granting of any options under
the Plan and the issuance of any shares of Common Stock (i) upon the exercise of
any option or (ii) under the Stock Issuance Program shall be subject to the
Corporation's procurement of all approvals and permits required by regulatory
authorities having jurisdiction over the Plan, the options granted under it and
the shares of Common Stock issued pursuant to it.

          VII. NO EMPLOYMENT OR SERVICE RIGHTS

               Nothing in the Plan shall confer upon the Optionee or the
Participant any right to continue in Service for any period of specific duration
or interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.

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


RECITALS
- --------

          A.  The Board has adopted the Plan for the purpose of retaining the
services of selected Employees, non-employee members of the Board or the board
of directors of any Parent or Subsidiary and consultants and other independent
advisors in the service of the Corporation (or any Parent or Subsidiary).

          B.  Optionee is to render valuable services to the Corporation (or a
Parent or Subsidiary), and this Agreement is executed pursuant to, and is
intended to carry out the purposes of, the Plan in connection with the
Corporation's grant of an option to Optionee.

          C.  All capitalized terms in this Agreement shall have the meaning
assigned to them in the attached Appendix.

          NOW, THEREFORE, it is hereby agreed as follows:

          1.  Grant of Option. The Corporation hereby grants to Optionee, as of
the Grant Date, an option to purchase up to the number of Option Shares
specified in the Grant Notice. The Option Shares shall be purchasable from time
to time during the option term specified in Paragraph 2 at the Exercise Price.

          2.  Option Term. This option shall have a term of ten (10) years
measured from the Grant Date and shall accordingly expire at the close of
business on the Expiration Date, unless sooner terminated in accordance with
Paragraph 5 or 6.

          3.  Limited Transferability. During Optionee's lifetime, this option
shall be exercisable only by Optionee and shall not be assignable or
transferable other than by will or by the laws of descent and distribution
following Optionee's death.

          4.  Dates of Exercise. This option shall become exercisable for the
Option Shares in one or more installments as specified in the Grant Notice. As
the option becomes exercisable for such installments, those installments shall
accumulate, and the option shall remain exercisable for the accumulated
installments until the Expiration Date or sooner termination of the option term
under Paragraph 5 or 6.

          5.  Cessation of Service. The option term specified in Paragraph 2
shall terminate (and this option shall cease to be outstanding) prior to the
Expiration Date should any of the following provisions become applicable:

              (a)  Should Optionee cease to remain in Service for any reason
(other than death, Disability or Misconduct) while this option is outstanding,
then Optionee shall have a period of three (3) months (commencing with the date
of such cessation of Service) during which
<PAGE>

to exercise this option, but in no event shall this option be exercisable at
any time after the Expiration Date.

               (b)  Should Optionee die while this option is outstanding, then
the personal representative of Optionee's estate or the person or persons to
whom the option is transferred pursuant to Optionee's will or in accordance with
the laws of inheritance shall have the right to exercise this option. Such right
shall lapse, and this option shall cease to be outstanding, upon the earlier of
                                                                     -------
(i) the expiration of the twelve (12)-month period measured from the date of
Optionee's death or (ii) the Expiration Date.

               (c) Should Optionee cease Service by reason of Disability while
this option is outstanding, then Optionee shall have a period of twelve (12)
months (commencing with the date of such cessation of Service) during which to
exercise this option. In no event shall this option be exercisable at any time
after the Expiration Date.

          Note: Exercise of this option on a date later than three (3)
          ----
          months following cessation of Service due to Disability will
          result in loss of favorable Incentive Option treatment,
          unless such Disability constitutes Permanent Disability. In
          ------
          the event that Incentive Option treatment is not available,
          this option will be taxed as a Non-Statutory Option upon
          exercise.

               (d)  During the limited period of post-Service exercisability,
this option may not be exercised in the aggregate for more than the number of
Option Shares in which Optionee is, at the time of Optionee's cessation of
Service, vested pursuant to the Vesting Schedule specified in the Grant Notice
or the special vesting acceleration provisions of Paragraph 6. Upon the
expiration of such limited exercise period or (if earlier) upon the Expiration
Date, this option shall terminate and cease to be outstanding for any vested
Option Shares for which the option has not been exercised. To the extent
Optionee is not vested in the Option Shares at the time of Optionee's cessation
of Service, this option shall immediately terminate and cease to be outstanding
with respect to those shares.

               (e)  Should Optionee's Service be terminated for Misconduct, then
this option shall terminate immediately and cease to remain outstanding.

               (f)  In the event of a Corporate Transaction, the provisions of
Paragraph 6 shall govern the period for which this option is to remain
exercisable following Optionee's cessation of Service and shall supersede any
provisions to the contrary in this paragraph.

          6.   Accelerated Vesting.

               (a)  In the event of any Corporate Transaction, the Option Shares
at the time subject to this option but not otherwise vested shall automatically
vest in full so that this option shall, immediately prior to the effective date
of the Corporate Transaction, become fully exercisable for all of those Option
Shares and may be exercised for any or all of those Option Shares as fully-
vested shares of Common Stock. However, the Option Shares shall not vest on such
an accelerated basis if and to the extent: (i) this option is assumed by the
successor

                                       2
<PAGE>

corporation (or parent thereof) in the Corporate Transaction and the
Corporation's repurchase rights with respect to the unvested Option Shares are
assigned to such successor corporation (or parent thereof) or (ii) this option
is to be replaced with a cash incentive program of the successor corporation
which preserves the spread existing on the unvested Option Shares at the time of
the Corporate Transaction (the excess of the Fair Market Value of those Option
Shares over the Exercise Price payable for such shares) and provides for
subsequent payout in accordance with the same Vesting Schedule applicable to
those unvested Option Shares as set forth in the Grant Notice.

               (b) Immediately following the Corporate Transaction, this option
shall terminate and cease to be outstanding, except to the extent assumed by the
successor corporation (or parent thereof) in connection with the Corporate
Transaction.

               (c) If this option is assumed in connection with a Corporate
Transaction, then this option shall be appropriately adjusted, immediately after
such Corporate Transaction, to apply to the number and class of securities which
would have been issuable to Optionee in consummation of such Corporate
Transaction had the option been exercised immediately prior to such Corporate
Transaction, and appropriate adjustments shall also be made to the Exercise
Price, provided the aggregate Exercise Price shall remain the same.
       --------

               (d) This Agreement shall not in any way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

               7.  Adjustment in Option Shares. Should any change be made to the
Common Stock by reason of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares or other change affecting the
outstanding Common Stock as a class without the Corporation's receipt of
consideration, appropriate adjustments shall be made to (i) the total number
and/or class of securities subject to this option and (ii) the Exercise Price in
order to reflect such change and thereby preclude a dilution or enlargement of
benefits hereunder.

               8.  Shareholder Rights. The holder of this option shall not have
any shareholder rights with respect to the Option Shares until such person shall
have exercised the option, paid the Exercise Price and become the recordholder
of the purchased shares.

               9.  Manner of Exercising Option.

               (a) In order to exercise this option with respect to all or any
part of the Option Shares for which this option is at the time exercisable,
Optionee (or any other person or persons exercising the option) must take the
following actions:

                   (i)   Execute and deliver to the Corporation a Purchase
     Agreement for the Option Shares for which the option is exercised.

                    (ii) Pay the aggregate Exercise Price for the purchased

          only to the extent authorized by the Plan Administrator in accordance
          with Paragraph 14. Should the Common Stock be registered under Section
          12 of the 1934 Act at the time the option is exercised, then the
          Exercise Price may also be paid as follows:

                          (C)  in shares of Common Stock held by Optionee (or
          any other person or persons exercising the option) for the requisite
          period necessary to avoid a charge to the Corporation's earnings for
          financial reporting purposes and valued at Fair Market Value on the
          Exercise Date; or

                          (D)  to the extent the option is exercised for vested
          Option Shares, through a special sale and remittance procedure
          pursuant to which Optionee (or any other person or persons exercising
          the option) shall concurrently provide irrevocable instructions (a) to
          a Corporation-designated brokerage firm to effect the immediate sale
          of the purchased shares and remit to the Corporation, out of the sale
          proceeds available on the settlement date, sufficient funds to cover
          the aggregate Exercise Price payable for the purchased shares plus all
          applicable Federal, state and local income and employment taxes
          required to be withheld by the Corporation by reason of such exercise
          and (b) to the Corporation to deliver the certificates for the
          purchased shares directly to such brokerage firm in order to complete
          the sale.

               Except to the extent the sale and remittance procedure is
          utilized in connection with the option exercise, payment of the
          Exercise Price must accompany the Purchase Agreement delivered to the
          Corporation in connection with the option exercise.

                    (iii) Furnish to the Corporation appropriate documentation
that the person or persons exercising the option (if other than Optionee) have
the right to exercise this option.

                    (iv)  Execute and deliver to the Corporation such written
representations as may be requested by the Corporation in order for it to comply
with the applicable requirements of Federal and state securities laws.

                    (v)   Make appropriate arrangements with the Corporation (or
Parent or Subsidiary employing or retaining Optionee) for the satisfaction of
all Federal, state and local income and employment tax withholding requirements
applicable to the option exercise.

               (b)  As soon as practical after the Exercise Date, the
Corporation shall issue to or on behalf of Optionee (or any other person or
persons exercising this option) a certificate for the purchased Option Shares,
with the appropriate legends affixed thereto.

                                       4
<PAGE>

               (c)  In no event may this option be exercised for any fractional
shares.

               (a)  The exercise of this option and the issuance of the Option
Shares upon such exercise shall be subject to compliance by the Corporation and
Optionee with all applicable requirements of law relating thereto and with all
applicable regulations of any stock exchange (or the Nasdaq National Market, if
applicable) on which the Common Stock may be listed for trading at the time of
such exercise and issuance.

               (b)  The inability of the Corporation to obtain approval from any
regulatory body having authority deemed by the Corporation to be necessary to
the lawful issuance and sale of any Common Stock pursuant to this option shall
relieve the Corporation of any liability with respect to the non-issuance or
sale of the Common Stock as to which such approval shall not have been obtained.
The Corporation, however, shall use its best efforts to obtain all such
approvals.

          12.  Successors and Assigns. Except to the extent otherwise provided
in Paragraphs 3 and 6, the provisions of this Agreement shall inure to the

Corporation under the terms of this Agreement shall be in writing and addressed
to the Corporation at its principal corporate offices. Any notice required to be
given or delivered to Optionee shall be in writing and addressed to Optionee at
the address indicated below Optionee's signature line on the Grant Notice. All
notices shall be deemed effective upon personal delivery or upon deposit in the
U.S. mail, postage prepaid and properly addressed to the party to be notified.

          14.  Financing. The Plan Administrator may, in its absolute discretion
and without any obligation to do so, permit Optionee to pay the Exercise Price
for the purchased Option Shares by delivering a full-recourse, interest-bearing
promissory note secured by those Option Shares. The payment schedule in effect
for any such promissory note shall be established by the Plan Administrator in
its sole discretion.

          15.  Construction. This Agreement and the option evidenced hereby are
made and granted pursuant to the Plan and are in all respects limited by and
subject to the terms of the Plan. All decisions of the Plan Administrator with
respect to any question or issue arising under the Plan or this Agreement shall

          16.  Governing Law. The interpretation, performance and enforcement of
this Agreement shall be governed by the laws of the State of California without
resort to that State's conflict-of-laws rules.

          17.  Shareholder Approval. If the Option Shares covered by this
Agreement exceed, as of the Grant Date, the number of shares of Common Stock
which may be issued under the Plan as last approved by the shareholders, then
this option shall be void with respect to such excess shares, unless shareholder
approval of an amendment sufficiently increasing the number of shares of Common
Stock issuable under the Plan is obtained in accordance with the provisions of
the Plan.

          18.  Additional Terms Applicable to an Incentive Option. In the event
this option is designated an Incentive Option in the Grant Notice, the following
terms and conditions shall also apply to the grant:

               (a)  This option shall cease to qualify for favorable tax
treatment as an Incentive Option if (and to the extent) this option is exercised
for one or more Option Shares: (i) more than three (3) months after the date
Optionee ceases to be an Employee for any reason other than death or Permanent
Disability or (ii) more than twelve (12) months after the date Optionee ceases
to be an Employee by reason of Permanent Disability.

               (b)  This option shall not become exercisable in the calendar
year in which granted if (and to the extent) the aggregate Fair Market Value
(determined at the Grant Date) of the Common Stock for which this option would
otherwise first become exercisable in such calendar year would, when added to
the aggregate value (determined as of the respective date or dates of grant) of
the Common Stock and any other securities for which one or more other Incentive
Options granted to Optionee prior to the Grant Date (whether under the Plan or
any other option plan of the Corporation or any Parent or Subsidiary) first
become exercisable during the same calendar year, exceed One Hundred Thousand
Dollars ($100,000) in the aggregate. To the extent the exercisability of this
option is deferred by reason of the foregoing limitation, the deferred portion
shall become exercisable in the first calendar year or years thereafter in which
the One Hundred Thousand Dollar ($100,000) limitation of this Paragraph 18(b)
would not be contravened, but such deferral shall in all events end immediately
prior to the effective date of a Corporate Transaction in which this option is
not to be assumed, whereupon the option shall become immediately exercisable as
a Non-Statutory Option for the deferred portion of the Option Shares.

               (c)  Should Optionee hold, in addition to this option, one or
more other options to purchase Common Stock which become exercisable for the
first time in the same calendar year as this option, then the foregoing
limitations on the exercisability of such options as Incentive Options shall be
applied on the basis of the order in which such options are granted.

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

          AGREEMENT made as of this _____ day of ______________ 199___, by and
oCen Communications, Inc., a California corporation, and _________, Participant
in the Corporation's 1998 Stock Option/Stock Issuance Plan.

          All capitalized terms in this Agreement shall have the meaning
assigned to them in this Agreement or in the attached Appendix.

     A.  PURCHASE OF SHARES
         ------------------

          1.  Purchase. Participant hereby purchases ___________ shares of
              --------
Common Stock (the "Purchased Shares") pursuant to the provisions of the Stock
Issuance Program at the purchase price of $ ___________ per share (the "Purchase
Price").

          2.  Payment.  Concurrently with the delivery of this Agreement to the
              -------
Corporation,  Participant shall pay the Purchase Price for the Purchased Shares
in cash or through a full-recourse interest-bearing promissory payable in full
to the Corporation in one year and shall deliver a duly-executed blank
Assignment Separate from Certificate (in the form attached hereto as Exhibit I)
with respect to the Purchased Shares.

          3.  Shareholder Rights. Until such time as the Corporation exercises

the Repurchase Right or the First Refusal Right, Participant (or any successor
in interest) shall have all shareholder rights (including voting, dividend and
liquidation rights) with respect to the Purchased Shares, subject, however, to
the transfer restrictions of Articles B and C.

     B.  SECURITIES LAW COMPLIANCE
         -------------------------

          1.  Restricted Securities. The Purchased Shares have not been
              ---------------------
registered under the 1933 Act and are being issued to Participant in reliance
upon the exemption from such registration provided by SEC Rule 701 for stock
issuances under compensatory benefit plans such as the Plan. Participant hereby
confirms that Participant has been informed that the Purchased Shares are
restricted securities under the 1933 Act and may not be resold or transferred
unless the Purchased Shares are first registered under the Federal securities
laws or unless an exemption from such registration is available. Accordingly,
Participant hereby acknowledges that Participant is prepared to hold the
Purchased Shares for an indefinite period and that Participant is aware that SEC
Rule 144 issued under the 1933 Act which exempts certain resales of unrestricted
securities is not presently available to exempt the resale of the Purchased
Shares from the registration requirements of the 1933 Act.

          2.  Disposition of Purchased Shares. Participant shall make no
              -------------------------------
disposition of the Purchased Shares (other than a Permitted Transfer) unless and
until there is compliance with all of the following requirements:
<PAGE>

          (i)   Participant shall have provided the Corporation with a written
     summary of the terms and conditions of the proposed disposition.

          (ii)  Participant shall have complied with all requirements of this
     Agreement applicable to the disposition of the Purchased Shares.

          (iii) Participant shall have provided the Corporation with written
     assurances, in form and substance satisfactory to the Corporation, that (a)
     the proposed disposition does not require registration of the Purchased
     Shares under the 1933 Act or (b) all appropriate action necessary for
     compliance with the registration requirements of the 1933 Act or any
     exemption from registration available under the 1933 Act (including Rule
     144) has been taken.

          The Corporation shall not be required (i) to transfer on its books any
                                ---
Purchased Shares which have been sold or transferred in violation of the
provisions of this Agreement or (ii) to treat as the owner of the Purchased
                             --
Shares, or otherwise to accord voting, dividend or liquidation rights to, any
transferee to whom the Purchased Shares have been transferred in contravention
of this Agreement.

          3.  Restrictive Legends. The stock certificates for the Purchased
              -------------------
Shares shall be endorsed with one or more of the following restrictive legends:

          "The shares represented by this certificate have not been registered
under the Securities Act of 1933.  The shares may not be sold or offered for
sale in the absence of (a) an effective registration statement for the shares
under such Act, (b) a "no action" letter of the Securities and Exchange
Commission with respect to such sale or offer or (c) satisfactory assurances to
the Corporation that registration under such Act is not required with respect to
such sale or offer."

          "The shares represented by this certificate are subject to certain
repurchase rights and rights of first refusal granted to the Corporation and
accordingly may not be sold, assigned, transferred, encumbered, or in any manner
disposed of except in conformity with the terms of a written agreement dated
______________________, 199__ between the Corporation and the registered holder
of the shares (or the predecessor in interest to the shares).  A copy of such
agreement is maintained at the Corporation's principal corporate offices."

     C.  TRANSFER RESTRICTIONS
         ---------------------

          1.  Restriction on Transfer. Except for any Permitted Transfer,
              -----------------------
Participant shall not transfer, assign, encumber or otherwise dispose of any of
the Purchased Shares which are subject to the Repurchase Right. In addition,
Purchased Shares which are released from the Repurchase Right shall not be
transferred, assigned, encumbered or otherwise disposed of in contravention of
the First Refusal Right or the Market Stand-Off.

          2.  Transferee Obligations. Each person (other than the Corporation)
              ----------------------
to whom the Purchased Shares are transferred by means of a Permitted Transfer
must, as a condition precedent to the validity of such transfer, acknowledge in
writing to the Corporation that such person is bound by the provisions of this
Agreement and that the transferred shares are subject to

                                       2
<PAGE>

(i) the Repurchase Right, (ii) the First Refusal Right and (iii) the Market
Stand-Off, to the same extent such shares would be so subject if retained by
Participant.

          3.  Market Stand-Off.
              ----------------

               (a)  In connection with any underwritten public offering by the
Corporation of its equity securities pursuant to an effective registration
statement filed under the 1933 Act, including the Corporation's initial public
offering, Owner shall not sell, make any short sale of, loan, hypothecate,
pledge, grant any option for the purchase of, or otherwise dispose or transfer
for value or otherwise agree to engage in any of the foregoing transactions with
respect to, any Purchased Shares without the prior written consent of the
Corporation or its underwriters. Such restriction (the "Market Stand-Off") shall
be in effect for such period of time from and after the effective date of the
final prospectus for the offering as may be requested by the Corporation or such
underwriters. In no event, however, shall such period exceed one hundred eighty
(180) days and the Market Stand-Off shall in all events terminate two (2) years
after the effective date of the Corporation's initial public offering.

               (b)  Owner shall be subject to the Market Stand-Off provided and
                                                                   ------------
only if the officers and directors of the Corporation are also subject to
- -------
similar restrictions.

               (c)  Any new, substituted or additional securities which are by
reason of any Recapitalization or Reorganization distributed with respect to the
Purchased Shares shall be immediately subject to the Market Stand-Off, to the
same extent the Purchased Shares are at such time covered by such provisions.

               (d)  In order to enforce the Market Stand-Off, the Corporation
may impose stop-transfer instructions with respect to the Purchased Shares until
the end of the applicable stand-off period.

          D.  REPURCHASE RIGHT
              ----------------

               1.  Grant. The Corporation is hereby granted the right (the
                   -----
"Repurchase Right"), exercisable at any time during the sixty (60)-day period
following the date Participant ceases for any reason to remain in Service, to
repurchase at the Purchase Price any or all of the Purchased Shares in which
Participant is not, at the time of his or her cessation of Service, vested in
accordance with the Vesting Schedule (such shares to be hereinafter referred to
as the "Unvested Shares").

               2.  Exercise of the Repurchase Right. The Repurchase Right shall
                   --------------------------------
be exercisable by written notice delivered to each Owner of the Unvested Shares
prior to the expiration of the sixty (60)-day exercise period. The notice shall
indicate the number of Unvested Shares to be repurchased and the date on which
the repurchase is to be effected, such date to be not more than thirty (30) days
after the date of such notice. The certificates representing the Unvested Shares
to be repurchased shall be delivered to the Corporation on or before the close
of business on the date specified for the repurchase. Concurrently with the
receipt of such stock certificates, the Corporation shall pay to Owner, in cash
or cash equivalents (including the cancellation of any purchase-money
indebtedness), an amount equal to the

                                       3
<PAGE>

Purchase Price previously paid for the Unvested Shares which are to be
repurchased from Owner.

          3.  Termination of the Repurchase Right. The Repurchase Right shall
              -----------------------------------
terminate with respect to any Unvested Shares for which it is not timely
exercised under Paragraph D.2. In addition, the Repurchase Right shall terminate
and cease to be exercisable with respect to any and all Purchased Shares in
which Participant vests in accordance with the following Vesting Schedule:

          Participant shall vest in twenty-five percent (25%) of the Purchased
Shares, and the Repurchase Right shall concurrently lapse with respect to those
Purchased Shares, upon Participant's completion of one (1) year of Service
measured from ________________________, 199____.

               Participant shall vest in the remaining seventy-five percent
     (75%) of the Purchased Shares, and the Repurchase Right shall concurrently
     lapse with respect to those Purchased Shares, in a series of thirty-six
     (36) successive equal monthly installments upon Participant's completion of
     each additional month of Service over the thirty-six (36)-month period
     measured from the vesting date for the first twenty-five percent (25%) of
     the Purchased Shares.

               All Purchased Shares as to which the Repurchase Right lapses
     shall, however, remain subject to (i) the First Refusal Right and (ii) the
     Market Stand-Off.

          4.  Recapitalization. Any new, substituted or additional securities or
              ----------------
other property (including cash paid other than as a regular cash dividend) which
is by reason of any Recapitalization distributed with respect to the Purchased
Shares shall be immediately subject to the Repurchase Right and any escrow
requirements hereunder, but only to the extent the Purchased Shares are at the
time covered by such right or escrow requirements. Appropriate adjustments to
reflect such distribution shall be made to the number and/or class of Purchased
Shares subject to this Agreement and to the price per share to be paid upon the
exercise of the Repurchase Right in order to reflect the effect of any such
Recapitalization upon the Corporation's capital structure; provided, however,
that the aggregate purchase price shall remain the same.

          5.  Corporate Transaction.
              ---------------------

               (a)  The Repurchase Right shall automatically terminate in its
entirety, and all the Purchased Shares shall vest in full, immediately prior to
the consummation of any Corporate Transaction, except to the extent the
Repurchase Right is to be assigned to the successor entity in such Corporate
Transaction.

               (b)  To the extent the Repurchase Right remains in effect
following a Corporate Transaction, such right shall apply to any new securities
or other property (including any cash payments) received in exchange for the
Purchased Shares in consummation of the Corporate Transaction, but only to the
extent the Purchased Shares are at the time covered by such right. Appropriate
adjustments shall be made to the price per share payable upon exercise of the
Repurchase Right to reflect the effect of the Corporate Transaction upon the
Corporation's

                                       4
<PAGE>

capital structure; provided, however, that the aggregate purchase price shall
                   --------
remain the same. The new securities or other property (including any cash
payments) issued or distributed with respect to the Purchased Shares in
consummation of the Corporate Transaction shall be immediately deposited in
escrow with the Corporation (or the successor entity) and shall not be released
from escrow until Participant vests in such securities or other property in
accordance with the same Vesting Schedule in effect for the Purchased Shares.

     E.  RIGHT OF FIRST REFUSAL
         ----------------------

          1.  Grant. The Corporation is hereby granted the right of first
              -----
refusal (the "First Refusal Right"), exercisable in connection with any proposed
transfer of the Purchased Shares in which Participant has vested in accordance
with the provisions of Article D. For purposes of this Article E, the term
"transfer" shall include any sale, assignment, pledge, encumbrance or other
disposition of the Purchased Shares intended to be made by Owner, but shall not
include any Permitted Transfer.

          2.  Notice of Intended Disposition. In the event any Owner of
              ------------------------------
Purchased Shares in which Participant has vested desires to accept a bona fide
third-party offer for the transfer of any or all of such shares (the Purchased
Shares subject to such offer to be hereinafter referred to as the "Target
Shares"), Owner shall promptly (i) deliver to the Corporation written notice
(the "Disposition Notice") of the terms of the offer, including the purchase
price and the identity of the third-party offeror, and (ii) provide satisfactory
proof that the disposition of the Target Shares to such third-party offeror
would not be in contravention of the provisions set forth in Articles B and C.

          3.  Exercise of the First Refusal Right. The Corporation shall, for a
              -----------------------------------
period of twenty-five (25) days following receipt of the Disposition Notice,
have the right to repurchase any or all of the Target Shares subject to the
Disposition Notice upon the same terms as those specified therein or upon such
other terms (not materially different from those specified in the Disposition
Notice) to which Owner consents. Such right shall be exercisable by delivery of
written notice (the "Exercise Notice") to Owner prior to the expiration of the
twenty-five (25)-day exercise period. If such right is exercised with respect to
all the Target Shares, then the Corporation shall effect the repurchase of such
shares, including payment of the purchase price, not more than five (5) business
days after delivery of the Exercise Notice; and at such time the certificates
representing the Target Shares shall be delivered to the Corporation.

          Should the purchase price specified in the Disposition Notice be
payable in property other than cash or evidences of indebtedness, the
Corporation shall have the right to pay the purchase price in the form of cash
equal in amount to the value of such property.  If Owner and the Corporation
cannot agree on such cash value within ten (10) days after the Corporation's
receipt of the Disposition Notice, the valuation shall be made by an appraiser
of recognized standing selected by Owner and the Corporation or, if they cannot
agree on an appraiser within twenty (20) days after the Corporation's receipt of
the Disposition Notice, each shall select an appraiser of recognized standing
and the two (2) appraisers shall designate a third appraiser of recognized
standing, whose appraisal shall be determinative of such value.  The cost of
such appraisal shall be shared equally by Owner and the Corporation.  The
closing shall then be held

                                       5
<PAGE>

on the later of (i) the fifth (5th) business day following delivery of the
       -----
Exercise Notice or (ii) the fifth (5th) business day after such valuation shall
have been made.

          4.  Non-Exercise of the First Refusal Right. In the event the Exercise
              ---------------------------------------
Notice is not given to Owner prior to the expiration of the twenty-five (25)-day
exercise period, Owner shall have a period of thirty (30) days thereafter in
which to sell or otherwise dispose of the Target Shares to the third-party
offeror identified in the Disposition Notice upon terms (including the purchase
price) no more favorable to such third-party offeror than those specified in the
Disposition Notice; provided, however, that any such sale or disposition must
not be effected in contravention of the provisions of Articles B and C. The
third-party offeror shall acquire the Target Shares free and clear of the
Repurchase Right and the First Refusal Right, but the acquired shares shall
remain subject to the provisions of Article B and Paragraph C.3. In the event
Owner does not effect such sale or disposition of the Target Shares within the
specified thirty (30)-day period, the First Refusal Right shall continue to be
applicable to any subsequent disposition of the Target Shares by Owner until
such right lapses.

          5.  Partial Exercise of the First Refusal Right. In the event the
              -------------------------------------------
Corporation makes a timely exercise of the First Refusal Right with respect to a
portion, but not all, of the Target Shares specified in the Disposition Notice,
Owner shall have the option, exercisable by written notice to the Corporation
delivered within five (5) business days after Owner's receipt of the Exercise
Notice, to effect the sale of the Target Shares pursuant to either of the
following alternatives:

               (i)  sale or other disposition of all the Target Shares to the
     third-party offeror identified in the Disposition Notice, but in full
     compliance with the requirements of Paragraph E.4, as if the Corporation
     did not exercise the First Refusal Right; or

               (ii) sale to the Corporation of the portion of the Target Shares
     which the Corporation has elected to purchase, such sale to be effected in
     substantial conformity with the provisions of Paragraph E.3. The First
     Refusal Right shall continue to be applicable to any subsequent disposition
     of the remaining Target Shares until such right lapses.

          Failure of Owner to deliver timely notification to the Corporation
shall be deemed to be an election by Owner to sell the Target Shares pursuant to
alternative (i) above.

          6.  Recapitalization/Reorganization.
              -------------------------------

               (a)  Any new, substituted or additional securities or other
     property which is by reason of any Recapitalization distributed with
     respect to the Purchased Shares shall be immediately subject to the First
     Refusal Right, but only to the extent the Purchased Shares are at the time
     covered by such right.

               (b)  In the event of a Reorganization, the First Refusal Right
     shall remain in full force and effect and shall apply to the new capital
     stock or other property received in exchange for the Purchased Shares in
     consummation of the Reorganization, but only to the extent the Purchased
     Shares are at the time covered by such right.

                                       6
<PAGE>

          7.  Lapse. The First Refusal Right shall lapse upon the earliest to
              -----
occur of (i) the first date on which shares of the Common Stock are held of
record by more than five hundred (500) persons, (ii) a determination is made by
the Board that a public market exists for the outstanding shares of Common Stock
or (iii) a firm commitment underwritten public offering, pursuant to an
effective registration statement under the 1933 Act, covering the offer and sale
of the Common Stock in the aggregate amount of at least ten million dollars
($10,000,000). However, the Market Stand-Off shall continue to remain in full
force and effect following the lapse of the First Refusal Right.

     F.  SPECIAL TAX ELECTION
         --------------------

          1.  Section 83(b) Election. Under Code Section 83, the excess of the
              ----------------------
Fair Market Value of the Purchased Shares on the date any forfeiture
restrictions applicable to such shares lapse over the Purchase Price paid for
such shares will be reportable as ordinary income on the lapse date. For this
purpose, the term "forfeiture restrictions" includes the right of the
Corporation to repurchase the Purchased Shares pursuant to the Repurchase Right.
Participant may elect under Code Section 83(b) to be taxed at the time the
Purchased Shares are acquired, rather than when and as such Purchased Shares
cease to be subject to such forfeiture restrictions. Such election must be filed
with the Internal Revenue Service within thirty (30) days after the date of this
Agreement. Even if the Fair Market Value of the Purchased Shares on the date of
this Agreement equals the Purchase Price paid (and thus no tax is payable), the
election must be made to avoid adverse tax consequences in the future. THE FORM
FOR MAKING THIS ELECTION IS ATTACHED AS EXHIBIT II HERETO. PARTICIPANT
UNDERSTANDS THAT FAILURE TO MAKE THIS FILING WITHIN THE APPLICABLE THIRTY (30)-
DAY PERIOD WILL RESULT IN THE RECOGNITION OF ORDINARY INCOME AS THE FORFEITURE
RESTRICTIONS LAPSE.

          2.  FILING RESPONSIBILITY. PARTICIPANT ACKNOWLEDGES THAT IT IS
PARTICIPANT'S SOLE RESPONSIBILITY, AND NOT THE CORPORATION'S, TO FILE A TIMELY
ELECTION UNDER CODE SECTION 83(b), EVEN IF PARTICIPANT REQUESTS THE CORPORATION
OR ITS REPRESENTATIVES TO MAKE THIS FILING ON HIS OR HER BEHALF.

     G.  GENERAL PROVISIONS
         ------------------

          1.  Assignment. The Corporation may assign the Repurchase Right and/or
              ----------
the First Refusal Right to any person or entity selected by the Board, including
(without limitation) one or more shareholders of the Corporation. If the
assignee of the Repurchase Right is other than (i) a wholly owned subsidiary of
the Corporation or (ii) the parent corporation owning one hundred percent (100%)
of the Corporation's outstanding capital stock, then such assignee must make a
cash payment to the Corporation, upon the assignment of the Repurchase Right, in
an amount equal to the excess (if any) of (i) the Fair Market Value of the
Purchased Shares at the time subject to the assigned Repurchase Right over (ii)
the aggregate repurchase price payable for the Purchased Shares.

          2.  No Employment or Service Contract. Nothing in this Agreement or in
              ---------------------------------
the Plan shall confer upon Participant any right to continue in Service for any
period of specific

                                       7
<PAGE>

duration or interfere with or otherwise restrict in any way the rights of the
Corporation (or any Parent or Subsidiary employing or retaining Participant) or
of Participant, which rights are hereby expressly reserved by each, to terminate

addressed to the party entitled to such notice at the address indicated below
such party's signature line on this Agreement or at such other address as such
party may designate by ten (10) days advance written notice under this paragraph
to all other parties to this Agreement.

          4.  No Waiver. The failure of the Corporation in any instance to
              ---------
exercise the Repurchase Right or the First Refusal Right shall not constitute a
waiver of any other repurchase rights and/or rights of first refusal that may
subsequently arise under the provisions of this Agreement or any other agreement
between the Corporation and Participant. No waiver of any breach or condition of
this Agreement shall be deemed to be a waiver of any other or subsequent breach
or condition, whether of like or different nature.

          5.  Cancellation of Shares. If the Corporation shall make available,
              ----------------------
at the time and place and in the amount and form provided in this Agreement, the
consideration for the Purchased Shares to be repurchased in accordance with the
provisions of this Agreement, then from and after such time, the person from
whom such shares are to be repurchased shall no longer have any rights as a
holder of such shares (other than the right to receive payment of such
consideration in accordance with this Agreement). Such shares shall be deemed
purchased in accordance with the applicable provisions hereof, and the
Corporation shall be deemed the owner and holder of such shares, whether or not
the certificates therefor have been delivered as required by this Agreement.

     H.  MISCELLANEOUS PROVISIONS
         ------------------------

          1.  Governing Law. This Agreement shall be governed by, and construed
              -------------
in accordance with, the laws of the State of California without resort to that
State's conflict-of-laws rules.

or more of the obligations or restrictions imposed on either Participant or the
Purchased Shares pursuant to the provisions of this Agreement.

              ----------------------------
entire contract between the parties hereto with regard to the subject matter
hereof. This Agreement is made pursuant to the provisions of the Plan and shall
in all respects be construed in conformity with the terms of the Plan.

<PAGE>

          4.  Counterparts. This Agreement may be executed in counterparts, each
              ------------
of which shall be deemed to be an original, but all of which together shall
constitute one and the same instrument.

          5.  Successors and Assigns. The provisions of this Agreement shall
              ----------------------
inure to the benefit of, and be binding upon, the Corporation and its successors
and assigns and upon Participant, Participant's assigns and the legal
representatives, heirs and legatees of Participant's estate, whether or not any

          This 2000 Stock Incentive Plan is intended to promote the interests of
oCen Communications, Inc., a Delaware corporation, by providing eligible persons
in the Corporation's service with the opportunity to acquire a proprietary
interest, or otherwise increase their proprietary interest, in the Corporation
as an incentive for them to remain in such service.

          Capitalized terms shall have the meanings assigned to such terms in
the attached Appendix.

     II.  STRUCTURE OF THE PLAN

          A.   The Plan shall be divided into five separate equity incentives
programs:

               -    the Discretionary Option Grant Program under which eligible
persons may, at the discretion of the Plan Administrator, be granted options to
purchase shares of Common Stock,

               -    the Salary Investment Option Grant Program under which
eligible employees may elect to have a portion of their base salary invested
each year in special option grants,

               -    the Stock Issuance Program under which eligible persons may,
at the discretion of the Plan Administrator, be issued shares of Common Stock
directly, either through the immediate purchase of such shares or as a bonus for
services rendered the Corporation (or any Parent or Subsidiary),

               -    the Automatic Option Grant Program under which eligible non-
employee Board members shall automatically receive option grants at designated
intervals over their period of continued Board service, and

               -    the Director Fee Option Grant Program under which
non-employee Board members may elect to have all or any portion of their annual
retainer fee otherwise payable in cash applied to a special stock option grant.

          B.   The provisions of Articles One and Seven shall apply to all
equity programs under the Plan and shall govern the interests of all persons
under the Plan.

     III. ADMINISTRATION OF THE PLAN

          A.   The Primary Committee shall have sole and exclusive authority to
administer the Discretionary Option Grant and Stock Issuance Programs with
respect to Section 16 Insiders. Administration of the Discretionary Option Grant
and Stock Issuance Programs with respect to all other persons eligible to
participate in those programs may, at the Board's discretion, be vested in the
Primary Committee or a Secondary Committee, or the Board may retain the power to
administer those programs with respect to all such persons. However, any
discretionary option grants or stock issuances for members of the Primary
Committee must be authorized by a disinterested majority of the Board.

          B.   Members of the Primary Committee or any Secondary Committee shall
serve for such period of time as the Board may determine and may be removed by
the Board at any time. The Board may also at any time terminate the functions of
any Secondary Committee and reassume all powers and authority previously
delegated to such committee.

          C.   Each Plan Administrator shall, within the scope of its
administrative functions under the Plan, have full power and authority (subject
to the provisions of the Plan) to establish such rules and regulations as it may
deem appropriate for proper administration of the Discretionary Option Grant and
Stock Issuance Programs and to make such determinations under, and issue such
interpretations of, the provisions of those programs and any outstanding options
or stock issuances thereunder as it may deem necessary or advisable. Decisions
of the Plan Administrator within the scope of its administrative functions under
the Plan shall be final and binding on all parties who have an interest in the
Discretionary Option Grant and Stock Issuance Programs under its jurisdiction or
any stock option or stock issuance thereunder.

          D.   The Primary Committee shall have the sole and exclusive authority
to determine which Section 16 Insiders and other highly compensated Employees
shall be eligible for participation in the Salary Investment Option Grant
Program for one or more calendar years. However, all option grants under the
Salary Investment Option Grant Program shall be made in accordance with the
express terms of that program, and the Primary Committee shall not exercise any
discretionary functions with respect to the option grants made under that
program.

          E.   Service on the Primary Committee or the Secondary Committee shall
constitute service as a Board member, and members of each such committee shall
accordingly be entitled to full indemnification and reimbursement as Board
members for their service on such committee. No member of the Primary Committee
or the Secondary Committee shall be liable for any act or omission made in good
faith with respect to the Plan or any option grants or stock issuances under the
Plan.

                                       2
<PAGE>

          F.   Administration of the Automatic Option Grant and Director Fee
Option Grant Programs shall be self-executing in accordance with the terms of
those programs, and no Plan Administrator shall exercise any discretionary
functions with respect to any option grants or stock issuances made under those
programs.

     IV.  ELIGIBILITY

          A.   The persons eligible to participate in the Discretionary Option
Grant and Stock Issuance Programs are as follows:

                    (i)   Employees,

                    (ii)  non-employee members of the Board or the board of
     directors of any Parent or Subsidiary, and

                    (iii) consultants and other independent advisors who provide
services to the Corporation (or any Parent or Subsidiary).

          B.   Only Employees who are Section 16 Insiders or other highly
compensated individuals shall be eligible to participate in the Salary
Investment Option Grant Program.

          C.   Each Plan Administrator shall, within the scope of its
administrative jurisdiction under the Plan, have full authority to determine,
(i) with respect to the option grants under the Discretionary Option Grant
Program, which eligible persons are to receive such grants, the time or times
when those grants are to be made, the number of shares to be covered by each
such grant, the status of the granted option as either an Incentive Option or a
Non-Statutory Option, the time or times when each option is to become
exercisable, the vesting schedule (if any) applicable to the option shares and
the maximum term for which the option is to remain outstanding and (ii) with
respect to stock issuances under the Stock Issuance Program, which eligible
persons are to receive such issuances, the time or times when the issuances are
to be made, the number of shares to be issued to each Participant, the vesting
schedule (if any) applicable to the issued shares and the consideration for such
shares.

          D.   The Plan Administrator shall have the absolute discretion either
to grant options in accordance with the Discretionary Option Grant Program or to
effect stock issuances in accordance with the Stock Issuance Program.

          E.   The individuals who shall be eligible to participate in the
Automatic Option Grant Program shall be limited to (i) those individuals who
first become non-employee Board members on or after the Underwriting Date,
whether through appointment by the Board or election by the Corporation's
stockholders, and (ii) those individuals who continue to serve as non-employee
Board members at one or more Annual Stockholders Meetings held after the
Underwriting Date. A non-employee Board member who has previously been in the
employ of the Corporation (or any Parent or Subsidiary) shall not be eligible to
receive an option grant

                                       3
<PAGE>

under the Automatic Option Grant Program at the time he or she first becomes a
non-employee Board member, but shall be eligible to receive periodic option
grants under the Automatic Option Grant Program while he or she continues to
serve as a non-employee Board member.

          F.   All non-employee Board members shall be eligible to participate
in the Director Fee Option Grant Program.

     V.   STOCK SUBJECT TO THE PLAN

          A.   The stock issuable under the Plan shall be shares of authorized
but unissued or reacquired Common Stock, including shares repurchased by the
Corporation on the open market. The number of shares of Common Stock initially
reserved for issuance over the term of the Plan shall not exceed
__________________ shares. Such reserve shall consist of (i) the number of
shares estimated to remain available for issuance, as of the Plan Effective
Date, under the Predecessor Plan as last approved by the Corporation's
stockholders, including the shares subject to outstanding options under the
Predecessor Plan, (ii) plus an additional increase of approximately
___________________ shares to be approved by the Corporation's stockholders
prior to the Underwriting Date.

          B.   The number of shares of Common Stock available for issuance under
the Plan shall automatically increase on the first trading day of January each
calendar year during the term of the Plan, beginning with calendar year 2001, by
an amount equal to ______ percent (___%) of the total number of shares of Common
Stock outstanding on the last trading day in December of the immediately
preceding calendar year, but in no event shall any such annual increase exceed
_________________ shares.

          C.   No one person participating in the Plan may receive stock
options, separately exercisable stock appreciation rights and direct stock
issuances for more than _______________ shares of Common Stock in the aggregate
per calendar year.

          D.   Shares of Common Stock subject to outstanding options (including
options incorporated into this Plan from the Predecessor Plan) shall be
available for subsequent issuance under the Plan to the extent (i) those options
expire or terminate for any reason prior to exercise in full or (ii) the options
are cancelled in accordance with the cancellation-regrant provisions of Article
Two. Unvested shares issued under the Plan and subsequently cancelled or
repurchased by the Corporation at the original issue price paid per share,
pursuant to the Corporation's repurchase rights under the Plan shall be added
back to the number of shares of Common Stock reserved for issuance under the
Plan and shall accordingly be available for reissuance through one or more
subsequent option grants or direct stock issuances under the Plan. However,
should the exercise price of an option under the Plan be paid with shares of
Common Stock or should shares of Common Stock otherwise issuable under the Plan
be withheld by the Corporation in satisfaction of the withholding taxes incurred
in connection with the exercise of an option or the vesting of a stock issuance
under the Plan, then the number of shares of Common Stock available for issuance
under the Plan shall be reduced by the gross number of shares for which the
option is exercised or which vest under the stock issuance, and not by the net
number of shares of Common Stock issued to the holder of such option or stock

                                       4
<PAGE>

issuance. Shares of Common Stock underlying one or more stock appreciation
rights exercised under Section IV of Article Two, Section III of Article Three,
Section II of Article Five or Section III of Article Six of the Plan shall not
be available for subsequent issuance under the Plan.

          E.   If any change is made to the Common Stock by reason of any stock
split, stock dividend, recapitalization, combination of shares, exchange of
shares or other change affecting the outstanding Common Stock as a class without
the Corporation's receipt of consideration, appropriate adjustments shall be
made by the Plan Administrator to (i) the maximum number and/or class of
securities issuable under the Plan, (ii) the maximum number and/or class of
securities for which any one person may be granted stock options, separately
exercisable stock appreciation rights and direct stock issuances under the Plan
per calendar year, (iii) the number and/or class of securities for which grants
are subsequently to be made under the Automatic Option Grant Program to new and
continuing non-employee Board members, (iv) the number and/or class of
securities and the exercise price per share in effect under each outstanding
option under the Plan, (v) the number and/or class of securities and exercise
price per share in effect under each outstanding option incorporated into this
Plan from the Predecessor Plan and (vi) the maximum number and/or class of
securities by which the share reserve is to increase automatically each calendar
year pursuant to the provisions of Section V.B of this Article One. Such
adjustments to the outstanding options are to be effected in a manner which
shall preclude the enlargement or dilution of rights and benefits under such
options. The adjustments determined by the Plan Administrator shall be final,
binding and conclusive.

                                  ARTICLE TWO

                      DISCRETIONARY OPTION GRANT PROGRAM
                      ----------------------------------

     I.   OPTION TERMS

          Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; provided, however, that each such document
                                    --------
shall comply with the terms specified below.  Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

          A.   Exercise Price.
               --------------

               1.   The exercise price per share shall be fixed by the Plan
Administrator but shall not be less than one hundred percent (100%) of the Fair
Market Value per share of Common Stock on the option grant date.

               2.   The exercise price shall become immediately due upon
exercise of the option and shall, subject to the provisions of Section I of
Article Seven and the documents evidencing the option, be payable in one or more
of the forms specified below:

                    (i)   cash or check made payable to the Corporation,

                    (ii)  shares of Common Stock held for the requisite period
     necessary to avoid a charge to the Corporation's earnings for financial
     reporting purposes and valued at Fair Market Value on the Exercise Date, or

                    (iii) to the extent the option is exercised for vested
     shares, through a special sale and remittance procedure pursuant to which
     the Optionee shall concurrently provide irrevocable instructions to (a) a
     Corporation-designated brokerage firm to effect the immediate sale of the
     purchased shares and remit to the Corporation, out of the sale proceeds
     available on the settlement date, sufficient funds to cover the aggregate
     exercise price payable for the purchased shares plus all applicable
     Federal, state and local income and employment taxes required to be
     withheld by the Corporation by reason of such exercise and (b) the
     Corporation to deliver the certificates for the purchased shares directly
     to such brokerage firm in order to complete the sale.

          Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

     B.   Exercise and Term of Options.  Each option shall be exercisable at
          ----------------------------
such time or times, during such period and for such number of shares as shall be
determined by the

                                       6
<PAGE>

Plan Administrator and set forth in the documents evidencing the option.
However, no option shall have a term in excess of ten (10) years measured from
the option grant date.

     C.   Effect of Termination of Service.
          --------------------------------

          1.   The following provisions shall govern the exercise of any options
held by the Optionee at the time of cessation of Service or death:

               (i)   Any option outstanding at the time of the Optionee's
     cessation of Service for any reason shall remain exercisable for such
     period of time thereafter as shall be determined by the Plan Administrator
     and set forth in the documents evidencing the option, but no such option
     shall be exercisable after the expiration of the option term.

               (ii)  Any option held by the Optionee at the time of death and
     exercisable in whole or in part at that time may be subsequently exercised
     by the personal representative of the Optionee's estate or by the person or
     persons to whom the option is transferred pursuant to the Optionee's will
     or the laws of inheritance or by the Optionee's designated beneficiary or
     beneficiaries of that option.

               (iii) Should the Optionee's Service be terminated for Misconduct
     or should the Optionee otherwise engage in Misconduct while holding one or
     more outstanding options under this Article Two, then all those options
     shall terminate immediately and cease to be outstanding.

               (iv)  During the applicable post-Service exercise period, the
     option may not be exercised in the aggregate for more than the number of
     vested shares for which the option is exercisable on the date of the
     Optionee's cessation of Service. Upon the expiration of the applicable
     exercise period or (if earlier) upon the expiration of the option term, the
     option shall terminate and cease to be outstanding for any vested shares
     for which the option has not been exercised. However, the option shall,
     immediately upon the Optionee's cessation of Service, terminate and cease
     to be outstanding to the extent the option is not otherwise at that time
     exercisable for vested shares.

          2.   The Plan Administrator shall have complete discretion,
exercisable either at the time an option is granted or at any time while the
option remains outstanding, to:

               (i)   extend the period of time for which the option is to remain
     exercisable following the Optionee's cessation of Service from the limited
     exercise period otherwise in effect for that option to such greater period
     of time as the Plan Administrator shall deem appropriate, but in no event
     beyond the expiration of the option term, and/or

                                       7
<PAGE>

               (ii) permit the option to be exercised, during the applicable
     post-Service exercise period, not only with respect to the number of vested
     shares of Common Stock for which such option is exercisable at the time of
     the Optionee's cessation of Service but also with respect to one or more
     additional installments in which the Optionee would have vested had the
     Optionee continued in Service.

          D.   Stockholder Rights.  The holder of an option shall have no
               ------------------
stockholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a
holder of record of the purchased shares.

          E.   Repurchase Rights.  The Plan Administrator shall have the
               -----------------
discretion to grant options which are exercisable for unvested shares of Common
Stock. Should the Optionee cease Service while holding such unvested shares, the
Corporation shall have the right to repurchase, at the exercise price paid per
share, any or all of those unvested shares. The terms upon which such repurchase
right shall be exercisable (including the period and procedure for exercise and
the appropriate vesting schedule for the purchased shares) shall be established
by the Plan Administrator and set forth in the document evidencing such
repurchase right.

          F.   Limited Transferability of Options.  During the lifetime of the
               ----------------------------------
Optionee, Incentive Options shall be exercisable only by the Optionee and shall
not be assignable or transferable other than by will or the laws of inheritance
following the Optionee's death. Non-Statutory Options shall be subject to the
same restriction, except that a Non-Statutory Option may be assigned in whole or
in part during the Optionee's lifetime to one or more members of the Optionee's
family or to a trust established exclusively for one or more such family members
or to Optionee's former spouse, to the extent such assignment is in connection
with the Optionee's estate plan or pursuant to a domestic relations order. The
assigned portion may only be exercised by the person or persons who acquire a
proprietary interest in the option pursuant to the assignment. The terms
applicable to the assigned portion shall be the same as those in effect for the
option immediately prior to such assignment and shall be set forth in such
documents issued to the assignee as the Plan Administrator may deem appropriate.
Notwithstanding the foregoing, the Optionee may also designate one or more
persons as the beneficiary or beneficiaries of his or her outstanding options
under this Article Two, and those options shall, in accordance with such
designation, automatically be transferred to such beneficiary or beneficiaries
upon the Optionee's death while holding those options. Such beneficiary or
beneficiaries shall take the transferred options subject to all the terms and
conditions of the applicable agreement evidencing each such transferred option,
including (without limitation) the limited time period during which the option
may be exercised following the Optionee's death.

     II.  INCENTIVE OPTIONS

          The terms specified below shall be applicable to all Incentive
Options.  Except as modified by the provisions of this Section II, all the
provisions of Articles One, Two and Seven shall be applicable to Incentive
Options.  Options which are specifically designated as Non-Statutory Options
when issued under the Plan shall not be subject to the terms of this Section II.
                                 ---

                                       8
<PAGE>

          A.   Eligibility.  Incentive Options may only be granted to Employees.
               -----------

          B.   Dollar Limitation. The aggregate Fair Market Value of the shares
               -----------------
of Common Stock (determined as of the respective date or dates of grant) for
which one or more options granted to any Employee under the Plan (or any other
option plan of the Corporation or any Parent or Subsidiary) may for the first
time become exercisable as Incentive Options during any one calendar year shall
not exceed the sum of One Hundred Thousand Dollars ($100,000). To the extent the
Employee holds two (2) or more such options which become exercisable for the
first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

          C.   10% Stockholder.  If any Employee to whom an Incentive Option is
               ---------------
granted is a 10% Stockholder, then the exercise price per share shall not be
less than one hundred ten percent (110%) of the Fair Market Value per share of
Common Stock on the option grant date, and the option term shall not exceed five
(5) years measured from the option grant date.

     III. CORPORATE TRANSACTION/CHANGE IN CONTROL

          A.   In the event of any Corporate Transaction, each outstanding
option shall automatically accelerate so that each such option shall,
immediately prior to the effective date of the Corporate Transaction, become
exercisable for all the shares of Common Stock at the time subject to such
option and may be exercised for any or all of those shares as fully vested
shares of Common Stock. However, an outstanding option shall not become
exercisable on such an accelerated basis if and to the extent: (i) such option
is, in connection with the Corporate Transaction, to be assumed by the successor
corporation (or parent thereof) or (ii) such option is to be replaced with a
cash incentive program of the successor corporation which preserves the spread
existing at the time of the Corporate Transaction on any shares for which the
option is not otherwise at that time exercisable and provides for subsequent
payout in accordance with the same exercise/vesting schedule applicable to those
option shares or (iii) the acceleration of such option is subject to other
limitations imposed by the Plan Administrator at the time of the option grant.

          B.   All outstanding repurchase rights shall automatically terminate,
and the shares of Common Stock subject to those terminated rights shall
immediately vest in full, in the event of any Corporate Transaction, except to
the extent: (i) those repurchase rights are to be assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction or
(ii) such accelerated vesting is precluded by other limitations imposed by the
Plan Administrator at the time the repurchase right is issued.

          C.   Immediately following the consummation of the Corporate
Transaction, all outstanding options shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

                                       9
<PAGE>

          D.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments to reflect such Corporate Transaction shall also be made
to (i) the exercise price payable per share under each outstanding option,
provided the aggregate exercise price payable for such securities shall remain
- --------
the same, (ii) the maximum number and/or class of securities available for
issuance over the remaining term of the Plan and (iii) the maximum number and/or
class of securities for which any one person may be granted stock options,
separately exercisable stock appreciation rights and direct stock issuances
under the Plan per calendar year and (iv) the maximum number and/or class of
securities by which the share reserve is to increase automatically each calendar
year. To the extent the actual holders of the Corporation's outstanding Common
Stock receive cash consideration for their Common Stock in consummation of the
Corporate Transaction, the successor corporation may, in connection with the
assumption of the outstanding options under the Discretionary Option Grant
Program, substitute one or more shares of its own common stock with a fair
market value equivalent to the cash consideration paid per share of Common Stock
in such Corporate Transaction.

          E.   The Plan Administrator shall have the discretionary authority to
structure one or more outstanding options under the Discretionary Option Grant
Program so that those options shall, immediately prior to the effective date of
such Corporate Transaction, become exercisable for all the shares of Common
Stock at the time subject to those options and may be exercised for any or all
of those shares as fully vested shares of Common Stock, whether or not those
options are to be assumed in the Corporate Transaction. In addition, the Plan
Administrator shall have the discretionary authority to structure one or more of
the Corporation's repurchase rights under the Discretionary Option Grant Program
so that those rights shall not be assignable in connection with such Corporate
Transaction and shall accordingly terminate upon the consummation of such
Corporate Transaction, and the shares subject to those terminated rights shall
thereupon vest in full.

          F.   The Plan Administrator shall have full power and authority to
structure one or more outstanding options under the Discretionary Option Grant
Program so that those options shall become exercisable for all the shares of
Common Stock at the time subject to those options in the event the Optionee's
Service is subsequently terminated by reason of an Involuntary Termination
within a designated period (not to exceed eighteen (18) months) following the
effective date of any Corporate Transaction in which those options are assumed
and do not otherwise accelerate. In addition, the Plan Administrator may
structure one or more of the Corporation's repurchase rights so that those
rights shall immediately terminate with respect to any shares held by the
Optionee at the time of his or her Involuntary Termination, and the shares
subject to those terminated repurchase rights shall accordingly vest in full at
that time.

                                      10
<PAGE>

          G.   The Plan Administrator shall have the discretionary authority to
structure one or more outstanding options under the Discretionary Option Grant
Program so that those options shall, immediately prior to the effective date of
a Change in Control, become exercisable for all the shares of Common Stock at
the time subject to those options and may be exercised for any or all of those
shares as fully vested shares of Common Stock. In addition, the Plan
Administrator shall have the discretionary authority to structure one or more of
the Corporation's repurchase rights under the Discretionary Option Grant Program
so that those rights shall terminate automatically upon the consummation of such
Change in Control, and the shares subject to those terminated rights shall
thereupon vest in full. Alternatively, the Plan Administrator may condition the
automatic acceleration of one or more outstanding options under the
Discretionary Option Grant Program and the termination of one or more of the
Corporation's outstanding repurchase rights under such program upon the
subsequent termination of the Optionee's Service by reason of an Involuntary
Termination within a designated period (not to exceed eighteen (18) months)
following the effective date of such Change in Control.

          H.   The portion of any Incentive Option accelerated in connection
with a Corporate Transaction or Change in Control shall remain exercisable as an
Incentive Option only to the extent the applicable One Hundred Thousand Dollar
($100,000) limitation is not exceeded. To the extent such dollar limitation is
exceeded, the accelerated portion of such option shall be exercisable as a
Nonstatutory Option under the Federal tax laws.

          I.   The outstanding options shall in no way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

     IV.  CANCELLATION AND REGRANT OF OPTIONS

          The Plan Administrator shall have the authority to effect, at any time
and from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Discretionary Option
Grant Program (including outstanding options incorporated from the Predecessor
Plan) and to grant in substitution new options covering the same or a different
number of shares of Common Stock but with an exercise price per share based on
the Fair Market Value per share of Common Stock on the new grant date.

     V.   STOCK APPRECIATION RIGHTS

          A.   The Plan Administrator shall have full power and authority to
grant to selected Optionees tandem stock appreciation rights and/or limited
stock appreciation rights.

          B.   The following terms shall govern the grant and exercise of tandem
stock appreciation rights:

                    (i)  One or more Optionees may be granted the right,
     exercisable upon such terms as the Plan Administrator may establish, to
     elect between the exercise of the underlying option for shares of Common
     Stock and

                                      11
<PAGE>

     the surrender of that option in exchange for a distribution from the
     Corporation in an amount equal to the excess of (a) the Fair Market Value
     (on the option surrender date) of the number of shares in which the
     Optionee is at the time vested under the surrendered option (or surrendered
     portion thereof) over (b) the aggregate exercise price payable for such
     shares.

                    (ii)  No such option surrender shall be effective unless it
     is approved by the Plan Administrator, either at the time of the actual
     option surrender or at any earlier time. If the surrender is so approved,
     then the distribution to which the Optionee shall be entitled may be made
     in shares of Common Stock valued at Fair Market Value on the option
     surrender date, in cash, or partly in shares and partly in cash, as the
     Plan Administrator shall in its sole discretion deem appropriate.

                    (iii) If the surrender of an option is not approved by the
     Plan Administrator, then the Optionee shall retain whatever rights the
     Optionee had under the surrendered option (or surrendered portion thereof)
     on the option surrender date and may exercise such rights at any time prior
     to the later of (a) five (5) business days after the receipt of the
            -----
     rejection notice or (b) the last day on which the option is otherwise
     exercisable in accordance with the terms of the documents evidencing such
     option, but in no event may such rights be exercised more than ten (10)
     years after the option grant date.

          C.   The following terms shall govern the grant and exercise of
limited stock appreciation rights:

                    (i)   One or more Section 16 Insiders may be granted limited
     stock appreciation rights with respect to their outstanding options.

                    (ii)  Upon the occurrence of a Hostile Take-Over, each
     individual holding one or more options with such a limited stock
     appreciation right shall have the unconditional right (exercisable for a
     thirty (30)-day period following such Hostile Take-Over) to surrender each
     such option to the Corporation. In return for the surrendered option, the
     Optionee shall receive a cash distribution from the Corporation in an
     amount equal to the excess of (A) the Take-Over Price of the shares of
     Common Stock at the time subject to such option (whether or not the option
     is otherwise at that time exercisable for those shares) over (B) the
     aggregate exercise price payable for those shares. Such cash distribution
     shall be paid within five (5) days following the option surrender date.

                    (iii) At the time such limited stock appreciation right is
granted, the Plan Administrator shall pre-approve any subsequent exercise of
that right in accordance with the terms of this Paragraph C. Accordingly, no
further approval of the Plan Administrator or the Board shall be required at the
time of the actual option surrender and cash distribution.

                                 ARTICLE THREE

                    SALARY INVESTMENT OPTION GRANT PROGRAM
                    --------------------------------------

     I.   OPTION GRANTS

          The Primary Committee shall have the sole and exclusive authority to
determine the calendar year or years (if any) for which the Salary Investment
Option Grant Program is to be in effect and to select the Section 16 Insiders
and other highly compensated Employees eligible to participate in the Salary
Investment Option Grant Program for such calendar year or years.  Each selected
individual who elects to participate in the Salary Investment Option Grant
Program must, prior to the start of each calendar year of participation, file
with the Plan Administrator (or its designate) an irrevocable authorization
directing the Corporation to reduce his or her base salary for that calendar
year by an amount not less than Ten Thousand Dollars ($10,000.00) nor more than
Fifty Thousand Dollars ($50,000.00).   Each individual who files such a timely
authorization shall automatically be granted an option under the Salary
Investment Grant Program on the first trading day in January of the calendar
year for which the salary reduction is to be in effect.

     II.  OPTION TERMS

          Each option shall be a Non-Statutory Option evidenced by one or more
documents in the form approved by the Plan Administrator; provided, however,
                                                          --------
that each such document shall comply with the terms specified below.

          A.   Exercise Price.
               --------------

               1.   The exercise price per share shall be thirty-three and
one-third percent (33-1/3%) of the Fair Market Value per share of Common Stock
on the option grant date.

               2.   The exercise price shall become immediately due upon
exercise of the option and shall be payable in one or more of the alternative
forms authorized under the Discretionary Option Grant Program. Except to the
extent the sale and remittance procedure specified thereunder is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

          B.   Number of Option Shares.  The number of shares of Common Stock
               -----------------------
subject to the option shall be determined pursuant to the following formula
(rounded down to the nearest whole number):

               X = A / (B x 66-2/3%), where

               X is the number of option shares,

                                      13
<PAGE>

               A is the dollar amount by which the Optionee's base salary is to
          be reduced for the calendar year pursuant to his or her election under
          the Salary Investment Option Grant Program, and

               B is the Fair Market Value per share of Common Stock on the
          option grant date.

          C.   Exercise and Term of Options.  The option shall become
               ----------------------------
exercisable in a series of twelve (12) successive equal monthly installments
upon the Optionee's completion of each calendar month of Service in the calendar
year for which the salary reduction is in effect. Each option shall have a
maximum term of ten (10) years measured from the option grant date.

          D.   Effect of Termination of Service.  Should the Optionee cease
               --------------------------------
Service for any reason while holding one or more options under this Article
Three, then each such option shall remain exercisable, for any or all of the
shares for which the option is exercisable at the time of such cessation of
Service, until the earlier of (i) the expiration of the ten (10)-year option
                   -------
term or (ii) the expiration of the three (3)-year period measured from the date
of such cessation of Service. Should the Optionee die while holding one or more
options under this Article Three, then each such option may be exercised, for
any or all of the shares for which the option is exercisable at the time of the
Optionee's cessation of Service (less any shares subsequently purchased by
Optionee prior to death), by the personal representative of the Optionee's
estate or by the person or persons to whom the option is transferred pursuant to
the Optionee's will or the laws of inheritance or by the designated beneficiary
or beneficiaries of the option. Such right of exercise shall lapse, and the
option shall terminate, upon the earlier of (i) the expiration of the ten
                                 -------
(10)-year option term or (ii) the three (3)-year period measured from the date
of the Optionee's cessation of Service. However, the option shall, immediately
upon the Optionee's cessation of Service for any reason, terminate and cease to
remain outstanding with respect to any and all shares of Common Stock for which
the option is not otherwise at that time exercisable.

     III. CORPORATE TRANSACTION/ CHANGE IN CONTROL/ HOSTILE TAKE-OVER

          A.   In the event of any Corporate Transaction while the Optionee
remains in Service, each outstanding option held by such Optionee under this
Salary Investment Option Grant Program shall automatically accelerate so that
each such option shall, immediately prior to the effective date of the Corporate
Transaction, become exercisable for all the shares of Common Stock at the time
subject to such option and may be exercised for any or all of those shares as
fully vested shares of Common Stock. Each such outstanding option shall
terminate immediately following the Corporate Transaction, except to the extent
assumed by the successor corporation (or parent thereof) in such Corporate
Transaction. Any option so assumed and shall remain exercisable for the fully
vested shares until the earlier of (i) the expiration of the ten (10)-year
option term or (ii) the expiration of the three (3)-year period measured from
the date of the Optionee's cessation of Service.

                                      14
<PAGE>

          B.   In the event of a Change in Control while the Optionee remains in
Service, each outstanding option held by such Optionee under this Salary
Investment Option Grant Program shall automatically accelerate so that each such
option shall, immediately prior to the effective date of the Change in Control,
become exercisable for all the shares of Common Stock at the time subject to
such option and may be exercised for any or all of those shares as fully vested
shares of Common Stock. The option shall remain so exercisable until the
earliest to occur of (i) the expiration of the ten (10)-year option term, (ii)
- --------
the expiration of the three (3)-year period measured from the date of the
Optionee's cessation of Service, (iii) the termination of the option in
connection with a Corporate Transaction or (iv) the surrender of the option in
connection with a Hostile Take-Over.

          C.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each
outstanding option granted him or her under the Salary Investment Option Grant
Program. The Optionee shall in return be entitled to a cash distribution from
the Corporation in an amount equal to the excess of (i) the Take-Over Price of
the shares of Common Stock at the time subject to the surrendered option
(whether or not the option is otherwise at the time exercisable for those
shares) over (ii) the aggregate exercise price payable for such shares. Such
cash distribution shall be paid within five (5) days following the surrender of
the option to the Corporation. The Primary Committee shall, at the time the
option with such limited stock appreciation right is granted under the Salary
Investment Option Grant Program, pre-approve any subsequent exercise of that
right in accordance with the terms of this Paragraph C. Accordingly, no further
approval of the Primary Committee or the Board shall be required at the time of
the actual option surrender and cash distribution.

          D.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to the exercise price payable per
share under each outstanding option, provided the aggregate exercise price
                                     --------
payable for such securities shall remain the same. To the extent the actual
holders of the Corporation's outstanding Common Stock receive cash consideration
for their Common Stock in consummation of the Corporate Transaction, the
successor corporation may, in connection with the assumption of the outstanding
options under the Salary Investment Option Grant Program, substitute one or more
shares of its own common stock with a fair market value equivalent to the cash
consideration paid per share of Common Stock in such Corporate Transaction.

          E.   The grant of options under the Salary Investment Option Grant
Program shall in no way affect the right of the Corporation to adjust,
reclassify, reorganize or otherwise change its capital or business structure or
to merge, consolidate, dissolve, liquidate or sell or transfer all or any part
of its business or assets.

                                      15

     IV.  REMAINING TERMS

          The remaining terms of each option granted under the Salary Investment
Option Grant Program shall be the same as the terms in effect for option grants
made under the Discretionary Option Grant Program.

                            STOCK ISSUANCE PROGRAM
                            ----------------------

     I.   STOCK ISSUANCE TERMS

          Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate issuances without any intervening option grants.
Each such stock issuance shall be evidenced by a Stock Issuance Agreement which
complies with the terms specified below.  Shares of Common Stock may also be
issued under the Stock Issuance Program pursuant to share right awards which
entitle the recipients to receive those shares upon the attainment of designated
performance goals.

          A.   Purchase Price.
               --------------

               1.   The purchase price per share shall be fixed by the Plan
Administrator, but shall not be less than one hundred percent (100%) of the Fair
Market Value per share of Common Stock on the issuance date.

               2.   Subject to the provisions of Section I of Article Seven,
shares of Common Stock may be issued under the Stock Issuance Program for any of
the following items of consideration which the Plan Administrator may deem
appropriate in each individual instance:

                    (i)  cash or check made payable to the Corporation, or

                    (ii) past services rendered to the Corporation (or any
     Parent or Subsidiary).

          B.   Vesting Provisions.
               ------------------

               1.   Shares of Common Stock issued under the Stock Issuance
Program may, in the discretion of the Plan Administrator, be fully and
immediately vested upon issuance or may vest in one or more installments over
the Participant's period of Service or upon attainment of specified performance
objectives. The elements of the vesting schedule applicable to any unvested
shares of Common Stock issued under the Stock Issuance Program shall be
determined by the Plan Administrator and incorporated into the Stock Issuance
Agreement. Shares of Common Stock may also be issued under the Stock Issuance
Program pursuant to share right awards which entitle the recipients to receive
those shares upon the attainment of designated performance goals.

               2.   Any new, substituted or additional securities or other
property (including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to the Participant's
unvested shares of Common Stock by reason of any stock dividend, stock split,
recapitalization, combination of shares, exchange of shares or

                                      17
<PAGE>

other change affecting the outstanding Common Stock as a class without the
Corporation's receipt of consideration shall be issued subject to (i) the same
vesting requirements applicable to the Participant's unvested shares of Common
Stock and (ii) such escrow arrangements as the Plan Administrator shall deem
appropriate.

               3.   The Participant shall have full stockholder rights with
respect to any shares of Common Stock issued to the Participant under the Stock
Issuance Program, whether or not the Participant's interest in those shares is
vested. Accordingly, the Participant shall have the right to vote such shares
and to receive any regular cash dividends paid on such shares.

               4.   Should the Participant cease to remain in Service while
holding one or more unvested shares of Common Stock issued under the Stock
Issuance Program or should the performance objectives not be attained with
respect to one or more such unvested shares of Common Stock, then those shares
shall be immediately surrendered to the Corporation for cancellation, and the
Participant shall have no further stockholder rights with respect to those
shares. To the extent the surrendered shares were previously issued to the
Participant for consideration paid in cash or cash equivalent (including the
Participant's purchase-money indebtedness), the Corporation shall repay to the
Participant the cash consideration paid for the surrendered shares and shall
cancel the unpaid principal balance of any outstanding purchase-money note of
the Participant attributable to the surrendered shares.

               5.   The Plan Administrator may in its discretion waive the
surrender and cancellation of one or more unvested shares of Common Stock which
would otherwise occur upon the cessation of the Participant's Service or the
non-attainment of the performance objectives applicable to those shares. Such
waiver shall result in the immediate vesting of the Participant's interest in
the shares of Common Stock as to which the waiver applies. Such waiver may be
effected at any time, whether before or after the Participant's cessation of
Service or the attainment or non-attainment of the applicable performance
objectives.

               6.   Outstanding share right awards under the Stock Issuance
Program shall automatically terminate, and no shares of Common Stock shall
actually be issued in satisfaction of those awards, if the performance goals
established for such awards are not attained. The Plan Administrator, however,
shall have the discretionary authority to issue shares of Common Stock under one
or more outstanding share right awards as to which the designated performance
goals have not been attained.

     II.  CORPORATE TRANSACTION/CHANGE IN CONTROL

          A.   All of the Corporation's outstanding repurchase rights under the
Stock Issuance Program shall terminate automatically, and all the shares of
Common Stock subject to those terminated rights shall immediately vest in full,
in the event of any Corporate Transaction, except to the extent (i) those
repurchase rights are to be assigned to the successor corporation (or parent
thereof) in connection with such Corporate Transaction or (ii) such accelerated
vesting is precluded by other limitations imposed in the Stock Issuance
Agreement.

                                      18
<PAGE>

          B.   The Plan Administrator shall have the discretionary authority to
structure one or more of the Corporation's repurchase rights under the Stock
Issuance Program so that those rights shall automatically terminate in whole or
in part, and the shares of Common Stock subject to those terminated rights shall
immediately vest, in the event the Participant's Service should subsequently
terminate by reason of an Involuntary Termination within a designated period
(not to exceed eighteen (18) months) following the effective date of any
Corporate Transaction in which those repurchase rights are assigned to the
successor corporation (or parent thereof).

          C.   The Plan Administrator shall also have the discretionary
authority to structure one or more of the Corporation's repurchase rights under
the Stock Issuance Program so that those rights shall automatically terminate in
whole or in part, and the shares of Common Stock subject to those terminated
rights shall immediately vest, in the event the Participant's Service should
subsequently terminate by reason of an Involuntary Termination within a
designated period (not to exceed eighteen (18) months) following the effective
date of any Change in Control.

     III. SHARE ESCROW/LEGENDS

     Unvested shares may, in the Plan Administrator's discretion, be held
in escrow by the Corporation until the Participant's interest in such shares
vests or may be issued directly to the Participant with restrictive legends on
the certificates evidencing those unvested shares.

                        AUTOMATIC OPTION GRANT PROGRAM
                        ------------------------------

     I.   OPTION TERMS

          A.   Grant Dates.  Option grants shall be made on the dates specified
               -----------
below:

               1.   Each individual who is first elected or appointed as a
non-employee Board member at any time on or after the Underwriting Date shall
automatically be granted, on the date of such initial election or appointment, a
Non-Statutory Option to purchase ______________ shares of Common Stock, provided
that individual has not previously been in the employ of the Corporation or any
Parent or Subsidiary.

               2.   On the date of each Annual Stockholders Meeting held after
the Underwriting Date, each individual who is to continue to serve as a
non-employee Board member, whether or not that individual is standing for
re-election to the Board at that particular Annual Meeting, shall automatically
be granted a Non-Statutory Option to purchase _________ shares of Common Stock,
provided such individual has served as a non-employee Board member for at least
six (6) months. There shall be no limit on the number of such ___________-share
option grants any one non-employee Board member may receive over his or her
period of Board service, and non-employee Board members who have previously been
in the employ of the Corporation (or any Parent or Subsidiary) or who have
otherwise received one or more stock option grants from the Corporation prior to
the Underwriting Date shall be eligible to receive one or more such annual
option grants over their period of continued Board service.

          B.   Exercise Price.
               --------------

               1.   The exercise price per share shall be equal to one hundred
percent (100%) of the Fair Market Value per share of Common Stock on the option
grant date.

               2.   The exercise price shall be payable in one or more of the
alternative forms authorized under the Discretionary Option Grant Program.
Except to the extent the sale and remittance procedure specified thereunder is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

          C.   Option Term.  Each option shall have a term of ten (10) years
               -----------
measured from the option grant date.

          D.   Exercise and Vesting of Options.  Each option shall be
               -------------------------------
immediately exercisable for any or all of the option shares. However, any
unvested shares purchased under the option shall be subject to repurchase by the
Corporation, at the exercise price paid per share, upon the Optionee's cessation
of Board service prior to vesting in those shares. The shares subject to each
initial ______________-share grant shall vest, and the Corporation's repurchase

                                      20
<PAGE>

right shall lapse, in a series of four (4) successive equal annual installments
upon the Optionee's completion of each year of service as a Board member over
the four (4)-year period measured from the option grant date. The shares subject
to each annual ____________-share option grant shall vest in one installment
upon the Optionee's completion of the one (1)-year period of service measured
from the grant date.

          E.   Limited Transferability of Options.  Each option under this
               ----------------------------------
Article Five may be assigned in whole or in part during the Optionee's lifetime
to one or more members of the Optionee's family or to a trust established
exclusively for one or more such family members or to Optionee's former spouse,
to the extent such assignment is in connection with the Optionee's estate plan
or pursuant to a domestic relations order. The assigned portion may only be
exercised by the person or persons who acquire a proprietary interest in the
option pursuant to the assignment. The terms applicable to the assigned portion
shall be the same as those in effect for the option immediately prior to such
assignment and shall be set forth in such documents issued to the assignee as
the Plan Administrator may deem appropriate. The Optionee may also designate one
or more persons as the beneficiary or beneficiaries of his or her outstanding
options under this Article Five, and those options shall, in accordance with
such designation, automatically be transferred to such beneficiary or
beneficiaries upon the Optionee's death while holding those options. Such
beneficiary or beneficiaries shall take the transferred options subject to all
the terms and conditions of the applicable agreement evidencing each such
transferred option, including (without limitation) the limited time period
during which the option may be exercised following the Optionee's death.

          F.   Termination of Board Service.  The following provisions shall
               ----------------------------
govern the exercise of any options held by the Optionee at the time the Optionee
ceases to serve as a Board member:

                    (i)   The Optionee (or, in the event of Optionee's death,
     the personal representative of the Optionee's estate or the person or
     persons to whom the option is transferred pursuant to the Optionee's will
     or the laws of inheritance or the designated beneficiary or beneficiaries
     of such option) shall have a twelve (12)-month period following the date of
     such cessation of Board service in which to exercise each such option.

                    (ii)  During the twelve (12)-month exercise period, the
     option may not be exercised in the aggregate for more than the number of
     vested shares of Common Stock for which the option is exercisable at the
     time of the Optionee's cessation of Board service.

                    (iii) Should the Optionee cease to serve as a Board member
     by reason of death or Permanent Disability, then all shares at the time
     subject to the option shall immediately vest so that such option may,
     during the twelve (12)-month exercise period following such cessation of
     Board service, be exercised for all or any portion of those shares as fully
     vested shares of Common Stock.

                                      21
<PAGE>

                    (iv) In no event shall the option remain exercisable after
     the expiration of the option term. Upon the expiration of the twelve
     (12)-month exercise period or (if earlier) upon the expiration of the
     option term, the option shall terminate and cease to be outstanding for any
     vested shares for which the option has not been exercised. However, the
     option shall, immediately upon the Optionee's cessation of Board service
     for any reason other than death or Permanent Disability, terminate and
     cease to be outstanding to the extent the option is not otherwise at that
     time exercisable for vested shares.

     II.  CORPORATE TRANSACTION/ CHANGE IN CONTROL/ HOSTILE TAKE-OVER

          A.   In the event of any Corporate Transaction while the Optionee
remains a Board member, the shares of Common Stock at the time subject to each
outstanding option under this Automatic Option Grant Program but not otherwise
vested shall automatically vest in full so that each such option shall,
immediately prior to the effective date of the Corporate Transaction, become
exercisable for all the option shares as fully vested shares of Common Stock and
may be exercised for any or all of those vested shares. Immediately following
the consummation of the Corporate Transaction, each automatic option grant shall
terminate and cease to be outstanding, except to the extent assumed by the
successor corporation (or parent thereof).

          B.   In connection with any Change in Control while the Optionee
remains a Board member, the shares of Common Stock at the time subject to each
outstanding option under this Automatic Option Grant Program but not otherwise
vested shall automatically vest in full so that each such option shall,
immediately prior to the effective date of the Change in Control, become
exercisable for all the option shares as fully vested shares of Common Stock and
may be exercised for any or all of those vested shares. Each such option shall
remain exercisable for such fully vested option shares until the expiration or
sooner termination of the option term or the surrender of the option in
connection with a Hostile Take-Over.

          C.   All outstanding repurchase rights under this under this Automatic
Option Grant Program shall automatically terminate, and the shares of Common
Stock subject to those terminated rights shall immediately vest in full, in the
event of any Corporate Transaction or Change in Control.

          D.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each of
his or her outstanding options under this Automatic Option Grant Program. The
Optionee shall in return be entitled to a cash distribution from the Corporation
in an amount equal to the excess of (i) the Take-Over Price of the shares of
Common Stock at the time subject to each surrendered option (whether or not the
Optionee is otherwise at the time vested in those shares) over (ii) the
aggregate exercise price payable for such shares. Such cash distribution shall
be paid within five (5) days following the surrender of the option to the
Corporation. No approval or consent of the Board or any Plan Administrator shall
be required at the time of the actual option surrender and cash distribution.

                                      22
<PAGE>

          E.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to the exercise price payable per
share under each outstanding option, provided the aggregate exercise price
                                     --------
payable for such securities shall remain the same. To the extent the actual
holders of the Corporation's outstanding Common Stock receive cash consideration
for their Common Stock in consummation of the Corporate Transaction, the
successor corporation may, in connection with the assumption of the outstanding
options under the Automatic Option Grant Program, substitute one or more shares
of its own common stock with a fair market value equivalent to the cash
consideration paid per share of Common Stock in such Corporate Transaction.

          F.   The grant of options under the Automatic Option Grant Program
shall in no way affect the right of the Corporation to adjust, reclassify,
reorganize or otherwise change its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its
business or assets.

     III. REMAINING TERMS

          The remaining terms of each option granted under the Automatic Option
Grant Program shall be the same as the terms in effect for option grants made
under the Discretionary Option Grant Program.

                                  ARTICLE SIX

                       DIRECTOR FEE OPTION GRANT PROGRAM
                       ---------------------------------

     I.   OPTION GRANTS

          The Primary Committee shall have the sole and exclusive authority to
determine the calendar year or years for which the Director Fee Option Grant
Program is to be in effect.  For each such calendar year the program is in
effect, each non-employee Board member may irrevocably elect to apply all or any
portion of the annual retainer fee otherwise payable in cash for his or her
service on the Board for that year to the acquisition of a special option grant
under this Director Fee Option Grant Program.  Such election must be filed with
the Corporation's Chief Financial Officer prior to the first day of the calendar
year for which the annual retainer fee which is the subject of that election is
otherwise payable.  Each non-employee Board member who files such a timely
election shall automatically be granted an option under this Director Fee Option
Grant Program on the first trading day in January in the calendar year for which
the annual retainer fee which is the subject of that election would otherwise be
payable in cash.

     II.  OPTION TERMS

          Each option shall be a Non-Statutory Option governed by the terms and
conditions specified below.

          A.   Exercise Price.
               --------------

               1.   The exercise price per share shall be thirty-three and
one-third percent (33-1/3%) of the Fair Market Value per share of Common Stock
on the option grant date.

               2.   The exercise price shall become immediately due upon
exercise of the option and shall be payable in one or more of the alternative
forms authorized under the Discretionary Option Grant Program. Except to the
extent the sale and remittance procedure specified thereunder is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

          B.   Number of Option Shares.  The number of shares of Common Stock
               -----------------------
subject to the option shall be determined pursuant to the following formula
(rounded down to the nearest whole number):

               X = A / (B x 66-2/3%), where

               X is the number of option shares,

               A is the portion of the annual retainer fee subject to the
          non-employee Board member's election under this Director Fee Option
          Grant Program, and

                                      24
<PAGE>

               B is the Fair Market Value per share of Common Stock on the
          option grant date.

          C.   Exercise and Term of Options.  The option shall become
               ----------------------------
exercisable in a series of twelve (12) equal monthly installments upon the
Optionee's completion of each calendar month of Board service during the
calendar year for which the retainer fee election is in effect. Each option
shall have a maximum term of ten (10) years measured from the option grant date.

          D.   Limited Transferability of Options.  Each option under this
               ----------------------------------
Article Six may be assigned in whole or in part during the Optionee's lifetime
to one or more members of the Optionee's family or to a trust established
exclusively for one or more such family members or to Optionee's former spouse,
to the extent such assignment is in connection with Optionee's estate plan or
pursuant to a domestic relations order. The assigned portion may only be
exercised by the person or persons who acquire a proprietary interest in the
option pursuant to the assignment. The terms applicable to the assigned portion
shall be the same as those in effect for the option immediately prior to such
assignment and shall be set forth in such documents issued to the assignee as
the Plan Administrator may deem appropriate. The Optionee may also designate one
or more persons as the beneficiary or beneficiaries of his or her outstanding
options under this Article Six, and those options shall, in accordance with such
designation, automatically be transferred to such beneficiary or beneficiaries
upon the Optionee's death while holding those options. Such beneficiary or
beneficiaries shall take the transferred options subject to all the terms and
conditions of the applicable agreement evidencing each such transferred option,
including (without limitation) the limited time period during which the option
may be exercised following the Optionee's death.

          E.   Termination of Board Service.  Should the Optionee cease Board
               ----------------------------
service for any reason (other than death or Permanent Disability) while holding
one or more options under this Director Fee Option Grant Program, then each such
option shall remain exercisable, for any or all of the shares for which the
option is exercisable at the time of such cessation of Board service, until the
earlier of (i) the expiration of the ten (10)-year option term or (ii) the
- -------
expiration of the three (3)-year period measured from the date of such cessation
of Board service. However, each option held by the Optionee under this Director
Fee Option Grant Program at the time of his or her cessation of Board service
shall immediately terminate and cease to remain outstanding with respect to any
and all shares of Common Stock for which the option is not otherwise at that
time exercisable.

          F.   Death or Permanent Disability.  Should the Optionee's service as
               -----------------------------
a Board member cease by reason of death or Permanent Disability, then each
option held by such Optionee under this Director Fee Option Grant Program shall
immediately become exercisable for all the shares of Common Stock at the time
subject to that option, and the option may be exercised for any or all of those
shares as fully vested shares until the earlier of (i) the expiration of the ten
                                        -------
(10)-year option term or (ii) the expiration of the three (3)-year period
measured from

                                      25
<PAGE>

the date of such cessation of Board service.  To the extent such option is held
by the Optionee at the time of his or death, that option may be exercised by the
personal representative of the Optionee's estate or by the person or persons to
whom the option is transferred pursuant to the Optionee's will or the laws of
inheritance or by the designated beneficiary or beneficiaries of such option.

               Should the Optionee die after cessation of Board service but
while holding one or more options under this Director Fee Option Grant Program,
then each such option may be exercised, for any or all of the shares for which
the option is exercisable at the time of the Optionee's cessation of Board
service (less any shares subsequently purchased by Optionee prior to death), by
the personal representative of the Optionee's estate or by the person or persons
to whom the option is transferred pursuant to the Optionee's will or the laws of
inheritance or by the designated beneficiary or beneficiaries of such option.
Such right of exercise shall lapse, and the option shall terminate, upon the
earlier of (i) the expiration of the ten (10)-year option term or (ii) the three
- -------
(3)-year period measured from the date of the Optionee's cessation of Board
service.

     III. CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

          A.   In the event of any Corporate Transaction while the Optionee
remains a Board member, each outstanding option held by such Optionee under this
Director Fee Option Grant Program shall automatically accelerate so that each
such option shall, immediately prior to the effective date of the Corporate
Transaction, become exercisable for all the shares of Common Stock at the time
subject to such option and may be exercised for any or all of those shares as
fully vested shares of Common Stock. Each such outstanding option shall
terminate immediately following the Corporate Transaction, except to the extent
assumed by the successor corporation (or parent thereof) in such Corporate
Transaction. Any option so assumed and shall remain exercisable for the fully
vested shares until the earlier of (i) the expiration of the ten (10)-year
                        -------
option term or (ii) the expiration of the three (3)-year period measured from
the date of the Optionee's cessation of Board service.

          B.   In the event of a Change in Control while the Optionee remains a
Board member, each outstanding option held by such Optionee under this Director
Fee Option Grant Program shall automatically accelerate so that each such option
shall, immediately prior to the effective date of the Change in Control, become
exercisable for all the shares of Common Stock at the time subject to such
option and may be exercised for any or all of those shares as fully vested
shares of Common Stock. The option shall remain so exercisable until the
earliest to occur of (i) the expiration of the ten (10)-year option term, (ii)
- --------
the expiration of the three (3)-year period measured from the date of the
Optionee's cessation of Board service, (iii) the termination of the option in
connection with a Corporate Transaction or (iv) the surrender of the option in
connection with a Hostile Take-Over.

          C.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each
outstanding option granted him or her under the Director Fee Option Grant
Program. The Optionee shall in return be

                                      26
<PAGE>

entitled to a cash distribution from the Corporation in an amount equal to the
excess of (i) the Take-Over Price of the shares of Common Stock at the time
subject to each surrendered option (whether or not the option is otherwise at
the time exercisable for those shares) over (ii) the aggregate exercise price
payable for such shares. Such cash distribution shall be paid within five (5)
days following the surrender of the option to the Corporation. No approval or
consent of the Board or any Plan Administrator shall be required at the time of
the actual option surrender and cash distribution.

          D.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to the exercise price payable per
share under each outstanding option, provided the aggregate exercise price
                                     --------
payable for such securities shall remain the same. To the extent the actual
holders of the Corporation's outstanding Common Stock receive cash consideration
for their Common Stock in consummation of the Corporate Transaction, the
successor corporation may, in connection with the assumption of the outstanding
options under the Director Fee Option Grant Program, substitute one or more
shares of its own common stock with a fair market value equivalent to the cash
consideration paid per share of Common Stock in such Corporate Transaction.

          E.   The grant of options under the Director Fee Option Grant Program
shall in no way affect the right of the Corporation to adjust, reclassify,
reorganize or otherwise change its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its
business or assets.

     IV.  REMAINING TERMS

          The remaining terms of each option granted under this Director Fee
Option Grant Program shall be the same as the terms in effect for option grants
made under the Discretionary Option Grant Program.

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

     I.   FINANCING

          The Plan Administrator may permit any Optionee or Participant to pay
the option exercise price under the Discretionary Option Grant Program or the
purchase price of shares issued under the Stock Issuance Program by delivering a
full-recourse, interest-bearing promissory note payable in one or more
installments.  The terms of any such promissory note (including the interest
rate and the terms of repayment) shall be established by the Plan Administrator
in its sole discretion.  In no event may the maximum credit available to the
Optionee or Participant exceed the sum of (i) the aggregate option exercise
price or purchase price payable for the purchased shares (less the par value of
such shares) plus (ii) any Federal, state and local income and employment tax
liability incurred by the Optionee or the Participant in connection with the
option exercise or share purchase.

     II.  TAX WITHHOLDING

          A.   The Corporation's obligation to deliver shares of Common Stock
upon the exercise of options or the issuance or vesting of such shares under the
Plan shall be subject to the satisfaction of all applicable Federal, state and
local income and employment tax withholding requirements.

          B.   The Plan Administrator may, in its discretion, provide any or all
holders of Non-Statutory Options or unvested shares of Common Stock under the
Plan (other than the options granted or the shares issued under the Automatic
Option Grant or Director Fee Option Grant Program) with the right to use shares
of Common Stock in satisfaction of all or part of the Withholding Taxes to which
such holders may become subject in connection with the exercise of their options
or the vesting of their shares. Such right may be provided to any such holder in
either or both of the following formats:

               Stock Withholding:  The election to have the Corporation
               -----------------
withhold, from the shares of Common Stock otherwise issuable upon the exercise
of such Non-Statutory Option or the vesting of such shares, a portion of those
shares with an aggregate Fair Market Value equal to the percentage of the
Withholding Taxes (not to exceed one hundred percent (100%)) designated by the
holder.

               Stock Delivery:  The election to deliver to the Corporation, at
               --------------
the time the Non-Statutory Option is exercised or the shares vest, one or more
shares of Common Stock previously acquired by such holder (other than in
connection with the option exercise or share vesting triggering the Withholding
Taxes) with an aggregate Fair Market Value equal to the percentage of the
Withholding Taxes (not to exceed one hundred percent (100%)) designated by the
holder.

                                      28
<PAGE>

     III. EFFECTIVE DATE AND TERM OF THE PLAN

          A.   The Plan shall become effective immediately on the Plan Effective
Date. However, the Salary Investment Option Grant Program and the Director Fee
Option Grant Program shall not be implemented until such time as the Primary
Committee may deem appropriate. Options may be granted under the Discretionary
Option Grant at any time on or after the Plan Effective Date, and the initial
option grants under the Automatic Option Grant Program shall also be made on the
Plan Effective Date to any non-employee Board members eligible for such grants
at that time. However, no options granted under the Plan may be exercised, and
no shares shall be issued under the Plan, until the Plan is approved by the
Corporation's stockholders. If such stockholder approval is not obtained within
twelve (12) months after the Plan Effective Date, then all options previously
granted under this Plan shall terminate and cease to be outstanding, and no
further options shall be granted and no shares shall be issued under the Plan.

          B.   The Plan shall serve as the successor to the Predecessor Plan,
and no further option grants or direct stock issuances shall be made under the
Predecessor Plan after the Plan Effective Date. All options outstanding under
the Predecessor Plan on the Plan Effective Date shall be incorporated into the
Plan at that time and shall be treated as outstanding options under the Plan.
However, each outstanding option so incorporated shall continue to be governed
solely by the terms of the documents evidencing such option, and no provision of
the Plan shall be deemed to affect or otherwise modify the rights or obligations
of the holders of such incorporated options with respect to their acquisition of
shares of Common Stock.

          C.   One or more provisions of the Plan, including (without
limitation) the option/vesting acceleration provisions of Article Two relating
to Corporate Transactions and Changes in Control, may, in the Plan
Administrator's discretion, be extended to one or more options incorporated from
the Predecessor Plan which do not otherwise contain such provisions.

          D.   The Plan shall terminate upon the earliest to occur of (i)
                                                 --------
____________, (ii) the date on which all shares available for issuance under the
Plan shall have been issued as fully vested shares or (iii) the termination of
all outstanding options in connection with a Corporate Transaction. Should the
Plan terminate on ______________, then all option grants and unvested stock
issuances outstanding at that time shall continue to have force and effect in
accordance with the provisions of the documents evidencing such grants or
issuances.

     IV.  AMENDMENT OF THE PLAN

          A.   The Board shall have complete and exclusive power and authority
to amend or modify the Plan in any or all respects. However, no such amendment
or modification shall adversely affect the rights and obligations with respect
to stock options or unvested stock issuances at the time outstanding under the
Plan unless the Optionee or the Participant consents to such amendment or
modification. In addition, certain amendments may require stockholder approval
pursuant to applicable laws or regulations.

                                      29
<PAGE>

          B.   Options to purchase shares of Common Stock may be granted under
the Discretionary Option Grant and Salary Investment Option Grant Programs and
shares of Common Stock may be issued under the Stock Issuance Program that are
in each instance in excess of the number of shares then available for issuance
under the Plan, provided any excess shares actually issued under those programs
shall be held in escrow until there is obtained stockholder approval of an
amendment sufficiently increasing the number of shares of Common Stock available
for issuance under the Plan. If such stockholder approval is not obtained within
twelve (12) months after the date the first such excess issuances are made, then
(i) any unexercised options granted on the basis of such excess shares shall
terminate and cease to be outstanding and (ii) the Corporation shall promptly
refund to the Optionees and the Participants the exercise or purchase price paid
for any excess shares issued under the Plan and held in escrow, together with
interest (at the applicable Short Term Federal Rate) for the period the shares
were held in escrow, and such shares shall thereupon be automatically cancelled
and cease to be outstanding.

     V.   USE OF PROCEEDS

          Any cash proceeds received by the Corporation from the sale of shares
of Common Stock under the Plan shall be used for general corporate purposes.

     VI.  REGULATORY APPROVALS

          A.   The implementation of the Plan, the granting of any stock option
under the Plan and the issuance of any shares of Common Stock (i) upon the
exercise of any granted option or (ii) under the Stock Issuance Program shall be
subject to the Corporation's procurement of all approvals and permits required
by regulatory authorities having jurisdiction over the Plan, the stock options
granted under it and the shares of Common Stock issued pursuant to it.

          B.   No shares of Common Stock or other assets shall be issued or
delivered under the Plan unless and until there shall have been compliance with
all applicable requirements of Federal and state securities laws, including the
filing and effectiveness of the Form S-8 registration statement for the shares
of Common Stock issuable under the Plan, and all applicable listing requirements
of any stock exchange (or the Nasdaq National Market, if applicable) on which
Common Stock is then listed for trading.

     VII. NO EMPLOYMENT/SERVICE RIGHTS

          Nothing in the Plan shall confer upon the Optionee or the Participant
any right to continue in Service for any period of specific duration or
interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.

Participant shall execute a stock purchase agreement embodying such terms and

<PAGE>

          Under no circumstances shall purchase rights be granted under the Plan

own (within the meaning of Code Section 424(d)) or hold outstanding options or
other rights to purchase, stock possessing five percent (5%) or more of the
total combined voting power or value of all classes of stock of the Corporation
or any Corporate Affiliate.

          B.   Exercise of the Purchase Right. Each purchase right shall be
               ------------------------------
automatically exercised in installments on each successive Purchase Date within
the offering period, and shares of Common Stock shall accordingly be purchased
on behalf of each Participant on each such Purchase Date. The purchase shall be
effected by applying the Participant's payroll deductions for the Purchase
Interval ending on such Purchase Date to the purchase of whole shares of Common
Stock at the purchase price in effect for the Participant for that Purchase
Date.

          C.   Purchase Price.  The purchase price per share at which Common
               --------------
Stock will be purchased on the Participant's behalf on each Purchase Date within
the offering period shall be equal to eighty-five percent (85%) of the lower of
(i) the Fair Market Value per share of Common Stock on the Participant's Entry
Date into that offering period or (ii) the Fair Market Value per share of Common
Stock on that Purchase Date.

          D.   Number of Purchasable Shares. The number of shares of Common
               ----------------------------
Stock purchasable by a Participant on each Purchase Date during the offering
period shall be the number of whole shares obtained by dividing the amount
collected from the Participant through payroll deductions during the Purchase
Interval ending with that Purchase Date by the purchase price in effect for the
Participant for that Purchase Date. However, the maximum number of shares of
Common Stock purchasable per Participant on any one Purchase Date shall not
exceed ___________ shares, subject to periodic adjustments in the event of
certain changes in the Corporation's capitalization. In addition, the maximum
number of shares of Common Stock purchasable in total by all Participants on any
one Purchase Date shall not exceed ____________ shares, subject to periodic
adjustments in the event of certain changes in the Corporation's capitalization.
However, the Plan Administrator shall have the discretionary authority,
exercisable prior to the start of any offering period under the Plan, to
increase or decrease the limitations to be in effect for the number of shares
purchasable per Participant and in total by all Participants on each Purchase
Date during that offering period.

          E.   Excess Payroll Deductions.  Any payroll deductions not applied
               -------------------------
to the purchase of shares of Common Stock on any Purchase Date because they are
not sufficient to purchase a whole share of Common Stock shall be held for the
purchase of Common Stock on the next Purchase Date. However, any payroll
deductions not applied to the purchase of Common Stock by reason of the
limitation on the maximum number of shares purchasable per Participant or in
total by all Participants on the Purchase Date shall be promptly refunded.

                                      4.
<PAGE>

          F.   Termination of Purchase Right.  The following provisions shall
               -----------------------------
govern the termination of outstanding purchase rights:

               (i)   A Participant may, at any time prior to the next scheduled
     Purchase Date in the offering period, terminate his or her outstanding
     purchase right by filing the appropriate form with the Plan Administrator
     (or its designate), and no further payroll deductions shall be collected
     from the Participant with respect to the terminated purchase right. Any
     payroll deductions collected during the Purchase Interval in which such
     termination occurs shall, at the Participant's election, be immediately
     refunded or held for the purchase of shares on the next Purchase Date. If
     no such election is made at the time such purchase right is terminated,
     then the payroll deductions collected with respect to the terminated right
     shall be refunded as soon as possible.

               (ii)  The termination of such purchase right shall be
     irrevocable, and the Participant may not subsequently rejoin the offering
     period for which the terminated purchase right was granted. In order to
     resume participation in any subsequent offering period, such individual
     must re-enroll in the Plan (by making a timely filing of the prescribed
     enrollment forms) on or before his or her scheduled Entry Date into that
     offering period.

               (iii) Should the Participant cease to remain an Eligible Employee
     for any reason (including death, disability or change in status) while his
     or her purchase right remains outstanding, then that purchase right shall
     immediately terminate, and all of the Participant's payroll deductions for
     the Purchase Interval in which the purchase right so terminates shall be
     immediately refunded. However, should the Participant cease to remain in
     active service by reason of an approved unpaid leave of absence, then the
     Participant shall have the right, exercisable up until the last business
     day of the Purchase Interval in which such leave commences, to (a) withdraw
     all the payroll deductions collected to date on his or her behalf for that
     Purchase Interval or (b) have such funds held for the purchase of shares on
     his or her behalf on the next scheduled Purchase Date. In no event,
     however, shall any further payroll deductions be collected on the
     Participant's behalf during such leave. Upon the Participant's return to
     active service (x) within ninety (90) days following the commencement of
     such leave or (y) prior to the expiration of any longer period for which
     such Participant's right to reemployment with the Corporation is guaranteed
     by statute or contract, his or her payroll deductions under the Plan shall
     automatically resume at the rate in effect at the time the leave began,
     unless the Participant withdraws from the Plan prior to his or her return.
     An individual who returns to active employment following a leave of absence
     that exceeds in duration the applicable (x) or (y) time period will be
     treated as a new Employee for purposes of subsequent participation in the
     Plan and must accordingly re-enroll in the Plan (by making a timely filing
     of the prescribed enrollment forms) on or before his or her scheduled Entry
     Date into the offering period.

                                      5.
<PAGE>

           G.   Change in Control.  Each outstanding purchase right shall
                -----------------
automatically be exercised, immediately prior to the effective date of any
Change in Control, by applying the payroll deductions of each Participant for
the Purchase Interval in which such Change in Control occurs to the purchase of
whole shares of Common Stock at a purchase price per share equal to eighty-five
percent (85%) of the lower of (i) the Fair Market Value per share of Common
Stock on the Participant's Entry Date into the offering period in which such
Change in Control occurs or (ii) the Fair Market Value per share of Common Stock
immediately prior to the effective date of such Change in Control. However, the
applicable limitation on the number of shares of Common Stock purchasable per
Participant shall continue to apply to any such purchase, but not the limitation
applicable to the maximum number of shares of Common Stock purchasable in total
by all Participants on any one Purchase Date.

           The Corporation shall use its best efforts to provide at least ten
(10) days' prior written notice of the occurrence of any Change in Control, and
Participants shall, following the receipt of such notice, have the right to
terminate their outstanding purchase rights prior to the effective date of the
Change in Control.

           H.   Proration of Purchase Rights. Should the total number of shares
                ----------------------------
of Common Stock to be purchased pursuant to outstanding purchase rights on any
particular date exceed the number of shares then available for issuance under
the Plan, the Plan Administrator shall make a pro-rata allocation of the
available shares on a uniform and nondiscriminatory basis, and the payroll
deductions of each Participant, to the extent in excess of the aggregate
purchase price payable for the Common Stock pro-rated to such individual, shall
be refunded.

           I.   Assignability.  The purchase right shall be exercisable only by
                -------------
the Participant and shall not be assignable or transferable by the Participant.

           J.   Stockholder Rights.  A Participant shall have no stockholder
                ------------------
rights with respect to the shares subject to his or her outstanding purchase
right until the shares are purchased on the Participant's behalf in accordance
with the provisions of the Plan and the Participant has become a holder of
record of the purchased shares.

     VIII. ACCRUAL LIMITATIONS

           A.   No Participant shall be entitled to accrue rights to acquire
Common Stock pursuant to any purchase right outstanding under this Plan if and
to the extent such accrual, when aggregated with (i) rights to purchase Common
Stock accrued under any other purchase right granted under this Plan and (ii)
similar rights accrued under other employee stock purchase plans (within the
meaning of Code Section 423)) of the Corporation or any Corporate Affiliate,
would otherwise permit such Participant to purchase more than Twenty-Five
Thousand Dollars ($25,000.00) worth of stock of the Corporation or any Corporate
Affiliate (determined on the basis of the Fair Market Value per share on the
date or dates such rights are granted) for each calendar year such rights are at
any time outstanding.

          B.    For purposes of applying such accrual limitations to the
purchase rights granted under the Plan, the following provisions shall be in
effect:

                                      6.
<PAGE>

               (i)  The right to acquire Common Stock under each outstanding
     purchase right shall accrue in a series of installments on each successive
     Purchase Date during the offering period on which such right remains
     outstanding.

               (ii) No right to acquire Common Stock under any outstanding
     purchase right shall accrue to the extent the Participant has already
     accrued in the same calendar year the right to acquire Common Stock under
     one or more other purchase rights at a rate equal to Twenty-Five Thousand
     Dollars ($25,000.00) worth of Common Stock (determined on the basis of the
     Fair Market Value per share on the date or dates of grant) for each
     calendar year such rights were at any time outstanding.

          C.   If by reason of such accrual limitations, any purchase right of a
Participant does not accrue for a particular Purchase Interval, then the payroll
deductions that the Participant made during that Purchase Interval with respect
to such purchase right shall be promptly refunded.

          D.   In the event there is any conflict between the provisions of this
Article and one or more provisions of the Plan or any instrument issued
thereunder, the provisions of this Article shall be controlling.

     IX.  EFFECTIVE DATE AND TERM OF THE PLAN

          A.   The Plan was adopted by the Board on ___________, 2000, and shall
become effective at the Effective Time, provided no purchase rights granted
under the Plan shall be exercised, and no shares of Common Stock shall be issued
hereunder, until (i) the Plan shall have been approved by the stockholders of
the Corporation and (ii) the Corporation shall have complied with all applicable
requirements of the 1933 Act (including the registration of the shares of Common
Stock issuable under the Plan on a Form S-8 registration statement filed with
the Securities and Exchange Commission), all applicable listing requirements of
any stock exchange (or the Nasdaq National Market, if applicable) on which the
Common Stock is listed for trading and all other applicable requirements
established by law or regulation. In the event such stockholder approval is not
obtained, or such compliance is not effected, within twelve (12) months after
the date on which the Plan is adopted by the Board, the Plan shall terminate and
have no further force or effect, and all sums collected from Participants during
the initial offering period hereunder shall be refunded.

          B.   Unless sooner terminated by the Board, the Plan shall terminate
upon the earliest of (i) the last business day in January 2010, (ii) the date on
which all shares available for issuance under the Plan shall have been sold
pursuant to purchase rights exercised under the Plan or (iii) the date on which
all purchase rights are exercised in connection with a Change in Control. No
further purchase rights shall be granted or exercised, and no further payroll
deductions shall be collected, under the Plan following such termination.

                                      7.
<PAGE>

     X.   AMENDMENT OF THE PLAN

          A.   The Board may alter, amend, suspend or terminate the Plan at any
time to become effective immediately following the close of any Purchase
Interval. However, the Plan may be amended or terminated immediately upon Board
action, if and to the extent necessary to assure that the Corporation will not
recognize, for financial reporting purposes, any compensation expense in
connection with the shares of Common Stock offered for purchase under the Plan,
should the financial accounting rules applicable to the Plan at the Effective
Time be subsequently revised so as to require the Corporation to recognize
compensation expense in the absence of such amendment or termination.

          B.   In no event may the Board effect any of the following amendments
or revisions to the Plan without the approval of the Corporation's stockholders:
(i) increase the number of shares of Common Stock issuable under the Plan,
except for permissible adjustments in the event of certain changes in the
Corporation's capitalization, (ii) alter the purchase price formula so as to
reduce the purchase price payable for the shares of Common Stock purchasable
under the Plan or (iii) modify the eligibility requirements for participation in
the Plan.

     XI.  GENERAL PROVISIONS

          A.   All costs and expenses incurred in the administration of the Plan
shall be paid by the Corporation; however, each Plan Participant shall bear all
costs and expenses incurred by such individual in the sale or other disposition
of any shares purchased under the Plan.

          B.   Nothing in the Plan shall confer upon the Participant any right
to continue in the employ of the Corporation or any Corporate Affiliate for any
period of specific duration or interfere with or otherwise restrict in any way
the rights of the Corporation (or any Corporate Affiliate employing such person)
or of the Participant, which rights are hereby expressly reserved by each, to
terminate such person's employment at any time for any reason, with or without
cause.

          C.   The provisions of the Plan shall be governed by the laws of the
State of New York without resort to that State's conflict-of-laws rules.

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
(together with the Company as provided in subsection 1.4(e)) enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting. Notwithstanding any other provision of this
Section 1.2, if the underwriter advises the Initiating Holders in writing that
marketing factors require a limitation of the number of shares to be
underwritten, then the Initiating Holders shall so advise all Holders of
Registrable Securities which would otherwise be underwritten pursuant hereto,
and the number of shares of Registrable Securities that may be included in the
underwriting shall be allocated among all Holders thereof, including the
Initiating Holders, in proportion (as nearly as practicable) to the amount of
Registrable Securities of the Company owned by each Holder; provided, however,
that the number of shares of Registrable Securities to be included in such
underwriting shall not be reduced unless all other securities are first entirely
excluded from the underwriting.

          (c)  Notwithstanding the foregoing, if the Company shall furnish to
Holders requesting a registration statement pursuant to this Section 1.2, a
certificate signed by the President 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 shareholders for such registration statement
to be filed and it is therefore beneficial to defer the filing of such
registration statement, the Company shall have the right to defer taking action
with respect to such filing for a period of not more than one hundred twenty
(120) days after receipt of the request of the Initiating Holders; provided,
however, that the Company may not utilize this right more than twice in any
twelve-month period.

          (d)  In addition, the Company shall not be obligated to effect, or to
take any action to effect, any registration pursuant to this Section 1.2:

               (i)  After the Company has effected one registration pursuant to
this Section 1.2 and such registration has been declared or ordered effective;

               (ii) During the period starting with the date ninety (90) days
prior to the Company's good faith estimate of the date of filing of, and ending
on a date one hundred eighty (180) days after the effective date of, a
registration subject to Section 1.3 hereof; provided that the Company is
actively employing in good faith all reasonable efforts to cause such
registration statement to become effective; or

                                      3.
<PAGE>

               (iii) If the Initiating Holders propose to dispose of shares of
Registrable Securities that may be immediately registered on Form S-3 pursuant
to a request made pursuant to Section 1.12 below.

          1.3  Company Registration. If the Company proposes to register
               --------------------
(including for this purpose a registration effected by the Company for
shareholders other than the Holders) any of its stock or other securities under
the Act in connection with the public offering of such securities solely for
cash (other than a registration relating solely to the sale of securities to
participants in a Company stock option plan, stock purchase plan, a registration
on any form which does not include substantially the same information as would
be required to be included in a registration statement covering the sale of the
Registrable Securities), the Company shall, at such time, promptly give each
Holder written notice of such registration. Upon the written request of each
Holder given within twenty (20) days after mailing of such notice by the Company
in accordance with Section 6.5, the Company shall, subject to the provisions of
Section 1.8, use its best efforts to cause to be registered under the Act all of
the Registrable Securities that each such Holder has requested to be registered.

          1.4  Obligations of the Company. Whenever required under this
               --------------------------
Section 1 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 its best efforts to cause such
registration statement to become effective, and keep such registration statement
effective for a period of up to one hundred twenty (120) days or until the
distribution contemplated in the Registration Statement has been completed;
provided, however, that (i) such 120-day period shall be extended for a period
of time equal to the period the Holder refrains from selling any securities
included in such registration at the request of an underwriter of Common Stock
(or other securities) of the Company; and (ii) in the case of any registration
of Registrable Securities on Form S-3 which are intended to be offered on a
continuous or delayed basis, such 120-day period shall be extended, if
necessary, to keep the registration statement effective until all such
Registrable Securities are sold, provided that Rule 415, or any successor rule
under the Act, permits an offering on a continuous or delayed basis, and
provided further that applicable rules under the Act governing the obligation to
file a post-effective amendment permit, in lieu of filing a post-effective
amendment which (I) includes any prospectus required by Section 10(a)(3) of the
Act or (II) reflects facts or events representing a material or fundamental
change in the information set forth in the registration statement, the
incorporation by reference of information required to be included in (I) and
(II) above to be contained in periodic reports filed pursuant to Section 13 or
15(d) of the 1934 Act in the registration statement.

          (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
Act with respect to the disposition of all securities covered by such
registration statement.

          (c)  Furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Act, and such other

                                      4.
<PAGE>

documents as they may reasonably request in order to facilitate the disposition
of Registrable Securities owned by them.

          (d)  Use its best 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, unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Act.

          (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 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 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.

          (g)  Cause all such Registrable Securities registered pursuant
hereunder to be listed on each securities exchange on which similar securities
issued by the Company are then listed.

          (h)  Provide a transfer agent and registrar for all Registrable
Securities registered pursuant hereunder and a CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such
registration.

          (i)  Furnish, at the request of any Holder requesting registration of
Registrable Securities pursuant to this Section 1, on the date that such
Registrable Securities are delivered to the underwriters for sale in connection
with a registration pursuant to this Section 1, 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 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, addressed to the underwriters, if any, and to the Holders requesting
registration of Registrable Securities and (ii) a letter dated 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, addressed to the underwriters,
if any, and to the Holders requesting registration of Registrable Securities.

          (j)  In the event that the Underwriters' Representatives establish a
directed share program (the "Program") in connection with the Company's initial
registered offering, subject to applicable law and NASD requirements, the
Company shall use its reasonable best

                                      5.
<PAGE>

efforts to offer to each Investor holding more than 1,000,000 shares of
Preferred Stock (a "Significant Investor") the opportunity to participate in the
Program (shares subject to the Program are hereinafter referred to as the
"Directed Shares"); provided, however, that in no event shall the aggregate
                    -----------------
number of Directed Shares exceed five (5) percent of the total number of shares
to be sold in the initial registered offering (excluding the number of shares,
if any, to be sold in connection with the exercise of the over-allotment option
by the Underwriters' Representatives), and provided further, that the
participation of any Significant Investor in the Program is conditioned upon the
approval of such participation by the Underwriters' Representatives and the
NASD. The number of Directed Shares that shall be allocated to each such
Significant Investor shall be calculated on a pro rata basis, so that each
Significant Investor shall have the option to purchase all or any part of that
number of Directed Shares equal to the product obtained by multiplying (i) the
aggregate number of Directed Shares by (ii) a fraction, the numerator of which
is the total number of outstanding shares of Preferred Stock (stated on an as-
converted basis, and as adjusted for stock splits, stock dividends,
recapitalizations and the like) held by such Significant Investor immediately
prior to the effectiveness of the Company's initial registered offering and the
denominator of which is the total number of shares of the Company's Preferred
Stock outstanding (stated on an as-converted basis, and as adjusted for stock
splits, stock dividends, recapitalizations and the like) and Common Stock (as
adjusted for stock splits, stock dividends, recapitalizations and the like)
immediately prior to the effectiveness of the Company's initial registered
offering. Each such Significant Investor shall have the option, but not the
obligation, to purchase the number of Directed Shares (as calculated pursuant to
the formula set forth in the preceding sentence) at the price per share at which
such shares are sold to the public in such registration.

          1.5  Furnish Information. It shall be a condition precedent to the
               -------------------
obligations of the Company to take any action pursuant to this Section 1 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities.

          1.6  Expenses of Demand Registration. All expenses, other than
               -------------------------------
underwriting discounts and commissions and fees and expenses of counsel to the
Holders incurred in connection with registrations, filings or qualifications
pursuant to Section 1.2, including (without limitation) all registration, filing
and qualification fees, printers' and accounting fees, and fees and
disbursements of counsel for the Company shall be borne by the Company, except
that the Company shall be required to pay up to but no more than $15,000 of the
fees and expenses incurred by one special legal counsel to such selling Holders,
any additional expenses or fees incurred by the special counsel to the selling
Holders shall be borne pro rata by such selling Holders; provided, however, that
the Company shall not be required to pay for any expenses of any registration
proceeding begun pursuant to Section 1.2 if the registration request is
subsequently withdrawn at the request of the Holders of a majority of the
Registrable Securities to be registered (in which case all participating Holders
shall bear such expenses on a pro rata basis), unless the Holders of a majority
of the Registrable Securities agree to forfeit their right to their demand
registration pursuant to Section 1.2; provided further, however, that if at the
time of such withdrawal, the Holders have learned of a material adverse change
in the condition, business, or prospects of the Company from that known to the
Holders at the time of their

                                      6.
<PAGE>

request and have withdrawn the request with reasonable promptness following
disclosure by the Company of such material adverse change, then the Holders
shall not be required to pay any of such expenses and shall retain their rights
pursuant to Section 1.2.

          1.7  Expenses of Company Registration. The Company shall bear and
               --------------------------------
pay all expenses incurred in connection with any registration, filing or
qualification of Registrable Securities with respect to the registrations
pursuant to Section 1.3 for each Holder (which right may be assigned as provided
in Section 1.13), including (without limitation) all registration, filing, and
qualification fees, printers and accounting fees relating or apportionable
thereto selected by them and up to $15,000 of the fees and expenses of one
special counsel to such Holders, but excluding underwriting discounts and
commissions and taxes relating to Registrable Securities.

          1.8  Underwriting Requirements. In connection with any offering
               -------------------------
involving an underwriting of shares of the Company's capital stock, the Company
shall not be required under Section 1.3 to include any of the Holders'
securities in such underwriting unless they accept the terms of the underwriting
as agreed upon between the Company and the underwriters selected by it (or by
other persons entitled to select the underwriters), and then only in such
quantity as the underwriters determine in their sole discretion will not
jeopardize the success of the offering by the Company. If the total amount of
securities, including Registrable Securities, requested by shareholders to be
included in such offering exceeds the amount of securities sold other than by
the Company than the underwriters determine in their sole discretion is
compatible with the success of the offering, then in such event the Company
shall be required to include in the offering only that number of such
securities, including Registrable Securities, which the underwriters determine
in their sole discretion will not jeopardize the success of the offering;
provided, however that any such limitation by the underwriters will be
apportioned as follows: (i) first the Common Stock held by officers, directors
or affiliates of the Company will be excluded from the registration, (ii) next
the securities other than Registrable Securities will be excluded from the
registration and (iii) last the Registrable Securities requested to be
registered by the Holders shall be excluded from such registration to the extent
required by the underwriters. If a limitation of the number of shares is still
required, the number of shares of Registrable Securities that may be included in
the registration and underwriting shall be allocated among all Holders in
proportion, as nearly as practicable, to the respective amounts of Registrable
Securities requested for inclusion in such Registration held by such Holders at
the time of filing the registration statement. No Registrable Securities or
other securities excluded from the underwriting by reason of this Section 1.8
shall be included in such registration statement. For purposes of the preceding
sentence concerning apportionment, for any selling shareholder which is a Holder
of Registrable Securities and which is a partnership or corporation, the
partners, retired partners and shareholders of such holder, or the estates and
family members of any such partners and retired partners and any trusts for the
benefit of any of the foregoing persons shall be deemed to be a single "selling
shareholder," and any pro-rata reduction with respect to such "selling
shareholder" shall be based upon the aggregate amount of shares carrying
registration rights owned by all entities and individuals included in such
"selling shareholder," as defined in this sentence. Notwithstanding the
foregoing, in the case of any registered public offering subsequent to the
Company's initial public offering, the number of Registrable Securities included
in such registration and underwriting shall not be reduced below 25% of the
securities included in such registration.

                                      7.
<PAGE>

          1.9  Delay of Registration. 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 1.

          1.10 Indemnification. In the event any Registrable Securities are
               ---------------
included in a registration statement under this Section 1:

          (a)  To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, any underwriter (as defined in the Act) for such
Holder and each person, if any, who controls such Holder or underwriter within
the meaning of the Act or the 1934 Act, against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the Act,
the 1934 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"): (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 Act, the 1934 Act, any state securities law or
any rule or regulation promulgated under the Act, the 1934 Act or any state
securities law; and the Company will reimburse each such Holder, underwriter or
controlling person, 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 subsection 1.10(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 for use in connection with such registration by
any such Holder, underwriter or controlling person.

          (b)  To the extent permitted by law, each selling Holder will
indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the registration statement, each person, if any, who
controls the Company within the meaning of the Act, any underwriter, any other
Holder selling securities in such registration statement and any controlling
person of any such underwriter or other Holder, against any losses, claims,
damages, or liabilities (joint or several) to which any of the foregoing persons
may become subject, under the Act, the 1934 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 for use in
connection with such registration; and each such Holder will pay any legal or
other expenses reasonably incurred by any person intended to be indemnified
pursuant to this subsection 1.10(b), in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity agreement contained in this subsection 1.10(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,

                                      8.
<PAGE>

that, in no event shall any indemnity under this subsection 1.10(b) exceed the
gross proceeds from the offering received by such Holder.

          (c)  Promptly after receipt by an indemnified party under this Section
1.10 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 1.10, 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
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate 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 prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
1.10, 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 1.10.

          (d)  If the indemnification provided for in this Section 1.10 is held
by a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any loss, liability, claim, damage, or expense referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, claim, damage, or expense
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 statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined 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.

          (e)  Notwithstanding the foregoing, to the extent that the provisions
on indemnification and contribution contained in the underwriting agreement
entered into in connection with the underwritten public offering are in conflict
with the foregoing provisions, the provisions in the underwriting agreement
shall control.

          (f)  The obligations of the Company and Holders under this Section
1.10 shall survive the completion of any offering of Registrable Securities in a
registration statement under this Section 1, and otherwise.

          1.11 Reports Under Securities Exchange Act of 1934. With a view to
               ---------------------------------------------
making available to the Holders the benefits of Rule 144 promulgated under the
Act and any other rule or

                                      9.
<PAGE>

regulation of the SEC that may at any time permit a Holder to sell securities of
the Company to the public without registration or pursuant to a registration on
Form S-3, the Company agrees to:

          (a)  make and keep public information available, as those terms are
understood and defined in SEC Rule 144, at all times after ninety (90) days
after the effective date of the first registration statement filed by the
Company for the offering of its securities to the general public;

          (b)  take such action, including the voluntary registration of its
Common Stock under Section 12 of the 1934 Act, as is necessary to enable the
Holders to utilize Form S-3 for the sale of their Registrable Securities, such
action to be taken as soon as practicable after the end of the fiscal year in
which the first registration statement filed by the Company for the offering of
its securities to the general public is declared effective;

          (c)  file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and

          (d)  furnish to any Holder, so long as the Holder owns any Registrable
Securities, forthwith upon request (i) a written statement by the Company that
it has complied with the reporting requirements of SEC Rule 144 (at any time
after ninety (90) days after the effective date of the first registration
statement filed by the Company), the Act and the 1934 Act (at any time after it
has become subject to such reporting requirements), or that it qualifies as a
registrant whose securities may be resold pursuant to Form S-3 (at any time
after it so qualifies), (ii) a copy of the most recent annual or quarterly
report of the Company and such other reports and documents so filed by the
Company, and (iii) such other information as may be reasonably requested in
availing any Holder of any rule or regulation of the SEC which permits the
selling of any such securities without registration or pursuant to such form.

          1.12 Form S-3 Registration. In case the Company shall receive from
               ---------------------
any Holder or Holders holding Registrable Securities then outstanding a written
request or requests that the Company effect a registration on Form S-3 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; and

          (b)  use its best efforts to effect, as soon as practicable, 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 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 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 1.12: (1) if Form S-3 is not available for such offering by the Holders;
(2) 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

                                      10.
<PAGE>

any) at an aggregate price to the public of less than $1,000,000; (3) if the
Company shall furnish to the Holders a certificate signed by the President of
the Company stating that in the good faith judgment of the Board of Directors of
the Company, it would be detrimental to the Company and its shareholders 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 1.12;
provided, however, that the Company shall not utilize this right more than twice
in any twelve month period; (4) if the Company has, within the twelve (12) month
period preceding the date of such request, already effected two registrations on
Form S-3 for the Holders pursuant to this Section 1.12; or (5) 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 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. All expenses incurred in connection with the registrations
requested pursuant to Section 1.12, including (without limitation) all
registration, filing, qualification, printer's and accounting fees and the fees
and disbursements of counsel for the Holders, but excluding any underwriters'
discounts or commissions and taxes, shall be borne pro rata by each of the
selling Holders. Registrations effected pursuant to this Section 1.12 shall not
be counted as demands for registration or registrations effected pursuant to
Sections 1.2 or 1.3, respectively.

          (d)  The Company shall not be obligated to effect any registration
pursuant to this Section 1.12 if the Company delivers to the Holders requesting
registration under this Section 1.12 an opinion, in form and substance
acceptable to such Holders, of counsel satisfactory to such Holders, that the
Registrable Securities so requested to be registered may be sold or transferred
pursuant to Rule 144(k) under the Act.

          1.13 Limitations on Subsequent Registration Rights. From and after
               ---------------------------------------------
the date of this Agreement, the Company shall not, without the prior written
consent of the Holders of a majority of the outstanding Registrable Securities,
enter into any agreement with any holder or prospective holder of any securities
of the Company which would allow such holder or prospective holder (a) to
include such securities in any registration filed under Section 1.2 hereof,
unless under the terms of such agreement, such holder or prospective holder may
include such securities in any such registration only to the extent that the
inclusion of such holder's securities will not reduce the amount of the
Registrable Securities of the Holders which is included or (b) to make a demand
registration which could result in such registration statement being declared
effective prior to the earlier of either of the dates set forth in subsection
1.2(a) or within one hundred twenty (120) days of the effective date of any
registration effected pursuant to Section 1.2.

          1.14 "Market Stand-Off" Agreement. The Investor hereby agrees that,
               ----------------------------
during the period of duration specified by the Company and an underwriter of
Common Stock or other securities of the Company, following the effective date of
the first registration statement of the Company filed under the Act, it shall
not, to the extent requested by the Company and such underwriter, directly or
indirectly sell, offer to sell, contract to sell (including, without limitation,

                                      11.
<PAGE>

any short sale), grant any option to purchase or otherwise transfer or dispose
of (other than to donees who agree to be similarly bound) any securities of the
Company held by it at any time during such period except Common Stock included
in such registration; provided, however, that:

          (a)  all executive officers and directors of the Company enter into
similar agreements; and

          (b)  such market stand-off time period shall not exceed 180 days.

          In order to enforce the foregoing covenant, the Company may impose
stop-transfer instructions with respect to the Registrable Securities of each
Investor (and the shares or securities of every other person subject to the
foregoing restriction) until the end of such period.

          Notwithstanding the foregoing, the obligations described in this
Section 1.14 shall not apply to a registration relating solely to employee
benefit plans on Form S-1 or Form S-8 or similar forms which may be promulgated
in the future, or a registration relating solely to a Commission Rule 145
transaction on Form S-14 or Form S-15 or similar forms which may be promulgated
in the future.

          1.15 Termination of Registration Rights. No Holder shall be entitled
               ----------------------------------
to exercise any right provided for in this Section 1 after three (3) years
following the consummation of the sale of securities pursuant to a registration
statement filed by the Company under the Act in connection with the initial firm
commitment underwritten offering of its securities to the general public at a
price per share of at least $9.37 (such offering price being subject to
proportional adjustment to reflect subdivisions, combinations, stock dividends
and similar transactions affecting the number of outstanding shares of Common
Stock) for aggregate gross offering proceeds to the Company (calculated before
deduction of underwriters' discounts and commissions) of at least $10,000,000,
or, with respect to any individual Holder or its transferee, when all
Registrable Securities held by such Holder may be sold under Rule 144 within a
given 90-day period.

          2.   Right Of First Offer. Subject to the terms and conditions
               --------------------
specified in this Section 2, the Company hereby grants to each Investor holding
at least 500,000 shares of Registrable Securities a right of first offer with
respect to future sales by the Company of its Shares (as hereinafter defined).
For purposes of this Section 2, Investors include any affiliates of the
Investors and any party to whom such Investor's rights under this Section 2 have
been duly assigned in accordance with Section 5 hereof. The Investors shall be
entitled to apportion the right of first offer hereby granted it among itself
and its affiliates in such proportions as it deems appropriate.

          2.1  Company Requirements. Each time the Company sells or otherwise
transfers any shares of, or securities convertible into or exercisable for any
shares of, any class of its capital stock ("Shares"), the Company shall first
make an offering of such Shares to the Investors in accordance with the
following provisions:

          (a)  The Company shall deliver a notice by certified mail ("Notice")
to the Investors stating (i) its bona fide intention to offer such Shares, (ii)
the number of such Shares to

                                      12.
<PAGE>

be offered, (iii) the price and terms, if any, upon which it proposes to offer
such Shares and (iv) the identity of proposed purchasers of the Shares.

          (b)  Within 10 days after giving of the Offer Notice, each Investor
may elect to purchase or obtain, at the price and on the terms specified in the
Offer Notice, up to that portion of the number of such Shares which equals the
proportion that the number of shares of Common Stock issued and held (assuming
conversion of the Preferred Stock then held), by such Investor bears to the
total number of shares of Common Stock issued and held (assuming conversion of
the Preferred Stock then held), by all of the Investors. In the event an
Investor fails to purchase such Investor's pro rata amount under the terms of
this Section 2, the Company shall promptly, in writing, inform the other
Investors electing to purchase their respective pro rata amounts. During the 10
day period commencing after receipt of such information, such other Investors
shall be entitled to obtain that portion of the Shares not so subscribed for
subject to the limitations in the first sentence of this paragraph.

          (c)  If all Shares are not elected to be obtained as provided in
subsection 2(b) hereof, the Company may, during the sixty (60) day period
following the expiration of the period provided in subsection 2(b) hereof, offer
the remaining unsubscribed portion of such Shares to any person or persons at a
price not less than, and upon terms no more favorable to the offeree than those
specified in the Offer Notice. If the Company does not sell the Shares within
such period, the right provided hereunder shall be deemed to be revived and such
Shares shall not be offered unless first reoffered to the Investors in
accordance herewith.

          (d)  The right of first offer in this paragraph 2 shall not be
applicable (i) to or after consummation of a bona fide, firmly underwritten
public offering of shares of Common Stock, registered under the Act pursuant to
a registration statement; (ii) the issuance of securities pursuant to the
conversion or exercise of convertible or exercisable securities provided that
such securities were offered to the Investors under this Section 2.1 or were
outstanding, or issued, on the date of this Agreement; (iii) the issuance of
securities in connection with a bona fide business acquisition of or by the
Company, whether by merger, consolidation, sale of assets, sale or exchange of
stock or otherwise approved by the Board of Directors; (iv) the issuance of
securities in connection with an equipment financing, a joint venture, a
partnership agreement, bank financings or lease lines approved by the Board of
Directors; or (v) the issuance of stock, warrants or other securities or rights
to service providers or employees as equity compensation.

          (e)  From and after the date of this Agreement, the Company shall not,
without the prior written consent of the Holders of a majority of the
outstanding Registrable Securities, enter into any agreement with any Holder or
prospective holder of any securities of the Company which would allow such
Holder or prospective Holder a right of first offer which is, in the good faith
judgment of the Board of Directors of the Company, on terms more favorable to
such Holder or prospective Holder than the right of first refusal granted in
this Section 2.

          2.2  Termination. This right of first offer shall terminate (i)
               -----------
immediately following the consummation of the sale of securities pursuant to a
registration statement filed by the Company under the Act in connection with the
initial firm commitment underwritten offering of its securities to the general
public at a price per share of at least $4.20 (such offering price being subject
to proportional adjustment to reflect subdivisions, combinations, stock
dividends

                                      13.
<PAGE>

and similar transactions affecting the number of outstanding shares of Common
Stock) for aggregate gross offering proceeds to the Company (calculated before
deduction of underwriters' discounts and commissions) of at least $10,000,000,
or (ii) upon (a) the acquisition of all or substantially all the assets of the
Company or (b) an acquisition of the Company by another corporation or entity by
consolidation or merger in which the holders of the Company's outstanding voting
stock immediately prior to such transaction own, immediately after such
transaction, securities representing less than 50% or more of the voting power
of the corporation or other entity surviving such transaction.

          3.   Right of First Refusal.
               ----------------------

          Each Investor hereby reaffirms that, pursuant to that certain Amended
and Restated Co-Sale Agreement dated the date hereof by and between the Company,
certain Founders (as defined therein) and certain Investors (as defined therein)
(the "Co-Sale Agreement"), they are concurrently herewith granting a "Right of
Refusal" (as that term is defined therein) to the Company and certain other
parties as set forth in the Co-Sale Agreement.

          4.   Information Rights.
               ------------------

          4.1  Financial Information. The Company covenants and agrees that,
               ---------------------

adjusted to reflect subdivisions, combinations, stock dividends, splits and
similar transactions), the Company will:

          (a)  Annual Reports.  Furnish to such Investor, as soon as
               --------------
practicable and in any event within 90 days after the end of each fiscal year of
the Company, an audited consolidated balance sheet as of the end of such fiscal
year and an audited consolidated statement of operations, an audited
consolidated statement of cash flows and an audited statement of stockholders'
equity of the Company for such year and detailed financial projections for the
next fiscal year, setting forth in each case in comparative form the figures
from the Company's previous fiscal year (if any), all prepared in accordance
with United States generally accepted accounting principles and practices,
consistently applied, and audited by an independent certified public accountant;

          (b)  Quarterly Reports.  Furnish to such Investor as soon as
               -----------------
practicable, and in any case within 30 days of the end of each fiscal quarter of
the Company (except the last quarter of the Company's fiscal year), quarterly
unaudited financial statements, including an unaudited balance sheet, an
unaudited statement of operations and an unaudited statement of cash flows, all
prepared in accordance with United States generally accepted accounting
principles, consistently applied; and

          (c)  Monthly Balance Sheets.  Within 20 days after the end of each
               ----------------------
calendar month, furnish to such Investor a balance sheet and a statement of
operations as of the end of such month, prepared in accordance with United
States generally accepted accounting principles, consistently applied.

          (d)  Each of the financial statements to be delivered by
Section 4.1(a), (b) and (c) shall, in a separate line item, reflect the number
of cards sold but not used.

                                      14.
<PAGE>

          4.2  Inspection Rights. For so long as the Investor holds at least
               -----------------
500,000 shares of Registrable Securities (as adjusted to reflect subdivisions,
combinations, stock dividends, splits and similar transactions), the Company
shall permit such Investor, at such Investor's expense, to visit and inspect the
Company's properties, to examine its books of account and records and to discuss
the Company's affairs, finances and accounts with its officers, at all such
reasonable times as may be requested by such Investor, provided, however, that
                                                       --------  -------
the Company shall not be obligated under this Section 4.2 to provide information
which it deems in good faith to be a trade secret or similar confidential
information if the Investor does not first execute an appropriate nondisclosure
agreement.

          4.3  Termination of Information Rights. The Company's obligations
               ---------------------------------
under Sections 4.1 through 4.2 above will terminate upon the earlier of: (i) the
consummation of the sale of securities pursuant to a registration statement
filed by the Company under the Act in connection with the initial firm
commitment underwritten offering of its securities to the general public at a
price per share of at least $9.37 (such offering price being subject to
proportional adjustment to reflect subdivisions, combinations, stock dividends
and similar transactions affecting the number of outstanding shares of Common
Stock) for aggregate gross offering proceeds to the Company (calculated before
deduction of underwriters' discounts and commissions) of at least $10,000,000,
or (ii) upon (a) the acquisition of all or substantially all the assets of the
Company or (b) an acquisition of the Company by another corporation or entity by

stock immediately prior to such transaction own, immediately after such
transaction, securities representing less than 50% or more of the voting power
of the corporation or other entity surviving such transaction.

          5.   Assignment of Rights.
               --------------------

          5.1  Assignment. Notwithstanding anything herein to the contrary:
               ----------

          (a)  Information Rights.  The rights of each Investor under Section 4

stating the name and address of the assignee and identifying the securities of
the Company as to which the rights in question are being assigned; and provided
                                                                       --------
