                               PROSPECTUS SUMMARY

   This summary highlights information contained elsewhere in this prospectus.
This summary is not complete and does not contain all the information you
should consider before buying shares in the offering. You should read the
entire prospectus carefully.

                              E-Stamp Corporation

Our Business

   We provide an easy-to-use Internet postage solution that enables users to
purchase, download and print postage directly from their personal computers.
The postage can be printed directly onto envelopes, labels or documents using
standard laser or inkjet printers, 24 hours a day, seven days a week, without
the need to remain connected to the Internet. We received approval from the
U.S. Postal Service in August 1999 for our Internet postage solution, and since
then have been selling our solution nationally. Our Internet postage solution
is targeted at small business, small office and home office users, collectively
known as SOHO users, most of whom usually connect to the Internet on modems at
speeds of 28.8 or 33.6 kilobytes per second and share lines with telephones or
fax machines. In addition, our Internet postage solution is tightly integrated
with popular business computer programs including Microsoft Word and Outlook,
and Intuit's Quickbooks. We believe our cost-effective Internet postage
solution will enhance customer satisfaction during the mail and postage process
by improving overall access, convenience and flexibility for SOHO users, and
will increase operating efficiencies and decrease postal fraud for the U.S.
Postal Service.

   We have focused on forming strategic relationships with industry leaders in
order to quickly build our brand awareness with SOHOs and to accelerate the
adoption of our Internet postage solution. Our strategic relationships include
the following:

  . Microsoft, which is also one of our equity investors, has selected us as
    its premium online postage partner for its Microsoft Office Update Web
    site;

  . Yahoo! has chosen us to be the premier Internet postage merchant within
    the Yahoo! Postal Center;

  . Excite@Home, which is also one of our equity investors, has entered into
    a binding letter of intent to establish us as the preferred Internet
    postage provider on its @Work Web site;

  . America Online has agreed to include us as a tenant in its new Postage
    Services Center, currently scheduled for launch in August 1999;

  . Compaq, which is also one of our equity investors, has agreed to market
    our Internet postage solution as part of the online services available to
    owners of its Prosignia line of personal computers for small businesses;

  . Francotyp-Postalia, which is also one of our equity investors, has agreed
    to distribute our Internet postage solution; and

  . Avery Dennison has agreed to promote exclusively our Internet postage
    solution in packages of Avery labels and other printable supplies.

   In addition, we have developed strategic relationships with Sunbeam Corp.'s
Pelouze Scale Co. division, Tension Envelope, EarthLink and Dymo-Costar.

Our Market Opportunity

   In an effort to enhance customer satisfaction, provide convenient postal
services, leverage users' existing investments in computer hardware and
software and improve access to the SOHO market, the U.S. Postal Service
developed the Information Based Indicia Program. This program is designed to
authorize third party

                                       3
<PAGE>

vendors to sell products or services that enable users to print postage, also
referred to as digital stamps, from a personal computer using ordinary laser or
inkjet printers. This new form of postage provides an opportunity to access the
U.S. postage market, which represented $60 billion in 1998. Of this amount,
$38 billion was represented by postage stamps and postage meters, which are
primarily used for first class, priority and express mail, which is the target
market for Internet postage. Keenan Vision, an independent research firm,
estimates that the market for first class, priority and express mail will grow
to $46 billion by the year 2002.

   The emergence of Internet postage has created an attractive channel for the
sale of postage to SOHO users currently underserved by existing solutions.
According to International Data Corporation, there were 44.7 million SOHOs in
the U.S. in 1998, which is expected to grow to 57.6 million by 2002. In terms
of postage usage, SOHOs generally conduct an essential part of their
communications with suppliers and customers through the postal system.
Nevertheless, few SOHOs use postage meters to automate the mailing process. In
addition, SOHOs are increasingly adopting the Internet to improve their
business processes.

Our Strategy

   Our objective is to be the leading provider of Internet postage solutions.
Key elements of our growth strategy include:

  . Partner with industry leaders to quickly acquire customers. We have
    formed strategic relationships with industry leaders to rapidly acquire
    customers, build brand recognition and accelerate adoption of our
    Internet postage solution. We anticipate continuing to add additional
    strategic partners as our business grows and we expand our portfolio of
    products and services.

  . Initially focus on the large and growing SOHO market. We are initially
    focusing on the SOHO market due to its attractive characteristics, such
    as a large and growing number of SOHOs, high personal computer
    penetration, and heavy reliance on the postal system for business
    communications.

  . Build and promote our brand. We intend to invest in building brand
    awareness through a variety of marketing and promotional techniques, both
    independently and in conjunction with our strategic partners. Our brand
    will be promoted through television, print and radio advertising, online
    banner advertising, and through viral marketing, such as including our
    logo and Web site address on each digital stamp.

  . Leverage our technology platform and expertise to extend our family of
    Internet postage solutions. We intend to leverage our customer-centric
    focus, scalable platform, and patent portfolio, currently consisting of
    over 20 issued patents, to develop a family of Internet postage
    solutions, including a server-based solution for the low-volume consumer
    and early adopters of broadband access and an intranet-based solution
    that will simplify routine processes for the high volume mailer and
    corporate enterprise.

  . Pursue multiple and recurring revenue streams. In addition to developing
    and marketing Internet postage solutions domestically, we are
    concentrating on the sale of postage related consumables and peripherals,
    and we intend to pursue international Internet postage opportunities and
    the purchase and printing of authenticated documents, such as tickets and
    gift certificates.

                                  RISK FACTORS

   You should carefully consider the risks described below before buying shares
in this offering.

We have a limited operating history with a history of losses, expect to incur
losses in the future, and may never achieve profitability.

   We have a very limited operating history. You should consider our prospects
in light of the risks and difficulties frequently encountered by early stage
companies in new and rapidly evolving markets. We cannot be certain that we
will achieve profitability or, if achieved, that we will be able to sustain or
increase profitability on a quarterly or annual basis. As of June 30, 1999, we
had not generated any revenues and had an accumulated deficit of $37.0 million.
Since U.S. Postal Service approval of our Internet postage solution in August
1999, we have generated only nominal revenues. We have not achieved
profitability and expect to continue to incur net losses for the foreseeable
future. We expect to incur increasing sales and marketing, research and
development and administrative expenses. As a result, we will need to generate
significant revenues to achieve and maintain profitability.

The success of our business will depend upon acceptance by customers of our
Internet postage solution.

   The U.S. Postal Service approved our Internet postage solution for
commercial sale in August 1999. We expect that our Internet postage solution
will generate a substantial portion, if not all, of our near-term future
revenues. As a result, we depend on the commercial acceptance of our Internet
postage solution. Any failure to successfully gain commercial acceptance of our
Internet postage solution would seriously harm our business and results of
operations. The market for Internet postage has not developed, and we cannot
assure you that it will develop. We cannot predict the extent to which users
will be willing to use the Internet to purchase postage rather than using
traditional methods. To the extent users choose to purchase postage over the
Internet, we cannot be certain that these customers will use our solution.

Intellectual property infringement claims, including claims asserted by Pitney
Bowes against us, could prevent or hinder our ability to sell Internet postage.

   We face the risk that other parties' intellectual property positions will
impair successful development of the Internet postage market or our ability to
effectively participate in it. Pitney Bowes filed a patent infringement lawsuit
against us in U.S. District Court in June 1999. The suit alleges infringement
of seven patents owned by Pitney Bowes related to postage application systems
and seeks treble damages, a preliminary and permanent injunction, attorneys'
fees and other unspecified damages. On July 30, 1999, we filed our answer to
Pitney Bowes' complaint in which we deny all allegations of patent
infringement, assert certain affirmative defenses based on statutory and common
law grounds, and bring antitrust counterclaims against Pitney Bowes. Pendency
of the litigation can be expected to result in significant expenses to us and
the diversion of management time and other resources. If Pitney Bowes is
successful in its claims against us, then we may be hindered or even prevented
from competing in the Internet postage market and our operations would be
severely harmed. The Pitney Bowes suit could result in limitations on how we
implement our solutions, delays and costs associated with redesigning our
solution and payments of license fees and other monies. An injunction obtained
by Pitney Bowes could eliminate our ability to market critical products or
services.

   Although we and Pitney Bowes, prior to filing of the current litigation, had
been in discussions regarding cross-licensing a number of our patents and
Pitney Bowes' patents, some of which are identified in the complaint, we cannot
predict whether these discussions will recommence in the future or the impact
of Pitney Bowes' intellectual property claims on our business or the Internet
postage market. Since commencement of the litigation, we have not had
discussions with Pitney Bowes regarding licensing or cross-licensing
arrangements nor do we have information concerning Pitney Bowes' present
willingness to engage in discussions.

                                       7

We cannot be certain that we will be able to continue to satisfy existing, new
or changed U.S. Postal Service regulations in the future, and if we are not
able to do so our business would suffer dramatically.

   Although the U.S. Postal Service has approved us to market and sell our
Internet postage solution nationally in accordance with approved quantities and
distribution channels, we will continue to be subject to U.S. Postal Service
scrutiny and other government regulations. If we encounter difficulties with
continuing compliance with U.S. Postal Service regulations, our ability to
distribute or extend the distribution of our Internet postage solution could be
adversely affected. Further, the U.S. Postal Service could change certification
requirements or specifications for Internet postage or revoke the approval of
our Internet postage solution. If we are unable to adapt our Internet postage
solution to any new requirements or specifications or if the U.S. Postal
Service discontinues Internet postage as an approved postage method, our
business will suffer dramatically. U.S. Postal Service regulations may require
that our personnel with access to postal information or resources obtain
security clearances, which may cause delays or disruptions in our business if
our personnel cannot receive necessary security clearances in a timely manner,
or at all, and may limit our ability to hire necessary personnel. Any other
change in the current or future regulatory environment could have an adverse
impact on our business and could harm our operating results and profitability.

If we cannot successfully manage the commercial availability of our Internet
postage solution, our business and reputation will be harmed.

   Our reputation and our ability to attract, retain and provide solutions to
our customers depend upon the reliable performance of our Web site, network
infrastructure and transaction-processing systems. If we are unable at any time
to provide our customers with our Internet postage solution in a satisfactory
manner, our business and reputation may be damaged. We will face numerous risks
concurrent with the introduction of our Internet postage solution. Under the
Information Based Indicia Program, the commercial roll-out of our Internet
postage solution is initially limited to 10,000 customers, with expanding
numbers of customers based upon successful evaluations by the U.S. Postal
Service. We have very limited experience conducting marketing campaigns, and we
may fail to generate significant interest in our Internet postage solution. On
the other hand, if we generate extensive interest in our solution, we cannot
assure you that we will be able to effectively manage commercial availability
of our Internet postage solution due to the strains this demand will place on
our Web site, network infrastructure and our transaction-processing systems.

If we are unable to maintain and develop our strategic relationships, our
Internet postage solution may not achieve commercial acceptance.

   We have established strategic relationships with a limited number of third
parties. These strategic relationships include sales, marketing and
distribution agreements. We rely heavily upon these relationships to build our
E-Stamp brand and to accelerate the adoption of our Internet postage solution.
We have limited experience in establishing and maintaining these relationships.
If we are unable to successfully maintain our existing relationships or to
establish new relationships, our business will suffer and our financial
condition and results of operation will be seriously harmed. In addition, given
the recent commercial launch of our Internet postage solution, a number of our
strategic partners are still in the process of establishing the marketing,
promotional and distribution activities for our solution called for under our
agreements with them. We cannot assure you that these efforts will be achieved
in a timely and successful manner and this would limit their usefulness in
promoting adoption of our solution.

If we do not achieve broad brand recognition, our business will suffer.

   We must quickly build our E-Stamp brand to gain market acceptance for our
solution. If we fail to gain market acceptance for our Internet postage
solution, our business will suffer dramatically. We believe it is imperative to
our long term success that we obtain significant acceptance of our solution. We
cannot be certain that we will have sufficient resources to build our brand and
achieve commercial acceptance of our solution. To

                                       8
<PAGE>

establish our brand awareness, we must invest substantial resources to develop
our products, pursue strategic relationships, implement marketing initiatives,
and provide a high quality experience to our users.

Subsequent Internet postage solutions, if successfully developed by us, will
require additional U.S. Postal Service approvals that may delay their
commercial introduction.

   Although we recently received approval from the U.S. Postal Service for our
Internet postage solution, we have not begun the approval process for future
solutions under development, including our server-based solution. Our Internet
postage solution took approximately 18 months to complete the beta test portion
of the U.S. Postal Service's approval process. While we believe subsequent
approvals should take less time because we may be able to leverage portions of
our prior approval experience, we cannot assure you of the duration of the
approval process for our server-based or any subsequent solution, or that these
solutions will ever be approved by the U.S. Postal Service. Further, we cannot
assure you that we will be able to successfully develop our future solutions in
a timely manner or at all. Failure to timely receive U.S. Postal Service
approval for our server-based solution or subsequent solutions could limit our
ability to successfully grow our business.

We have experienced significant growth in our business in recent periods, and
any failure to manage this growth could damage our business.

   Our ability to successfully offer our Internet postage solution and
implement our business plan requires an effective planning and management
process. We have increased, and plan to continue to increase, the scope of our
operations. If we are unable to manage growth effectively or experience
disruptions during our expansion, our business will suffer and our financial
condition and results of operations will be seriously harmed. To manage the
expected growth of operations and personnel, we will need to improve existing
and implement new transaction-processing, operational and financial systems,
procedures and controls. In addition, we will need to expand, train and manage
an increasing employee base and to expand our finance, administrative and
operations staff. Our current expansion has placed, and we expect our future
expansion to continue to place, a significant strain on our managerial,
operational and financial resources. Our current and planned personnel,
systems, procedures and controls may be inadequate to support our future
operations.

If the sole supplier of our Internet postage device is unable to timely meet
our commercial supply needs, our revenues and operating results would be
materially harmed.

   Dallas Semiconductor Corporation is the single source of supply for our
secure Internet postage device. We do not have a guaranteed supply arrangement
with Dallas Semiconductor, and we order such devices on a purchase order basis.
Any difficulties encountered by our sole supplier that result in product
defects, production delays, cost overruns, or the inability to fulfill orders
on a timely basis would hurt our reputation and harm our business. If we cannot
obtain an adequate supply of our Internet postage device, our operating results
and business would be materially and adversely harmed. Neither we nor our
supplier maintain an extensive inventory of our Internet postage device. We
cannot assure you that our supplier will timely meet our commercial supply
needs or that alternative suppliers will be available in the future. We have
not qualified any alternative sources for the supply of our secure Internet
postage device.

System failures could harm our business and reputation and substantially and
adversely affect our operating results.

   Our business and reputation with customers depend upon the efficient and
uninterrupted operation of our Web site, processing systems and network
infrastructure, including critical portions of this infrastructure that are
hosted by third parties, for registration of new customers and processing of
Internet postage transactions. In addition, our service depends upon continuous
operation of the U.S. Postal Service's secure postage accounting vault for our
customers to purchase postage. We have experienced system failure for short
periods during initial commercial launch of our service and we may suffer
additional interruptions in our service. Our customer acquisition and
processing systems and those of our third party hosted facilities contain
redundancy features but

                                       9
<PAGE>

are not fully redundant, and problems or system failures at either our location
or third party locations could result in interruptions in our service.
Unscheduled downtime of our service may result in loss of revenue and if these
system failures persist, our business, reputation and brand could be severely
harmed. We plan to expand our systems infrastructure on an ongoing basis but we
cannot assure you that we will be able to timely expand these capabilities to
support growth in traffic from our customers. In addition, our systems and
those hosted by third parties are vulnerable to damage or interruption as a
result of fire, flood, power loss, telecommunications failure, software errors
or bugs, hardware failures or computer viruses, computer hacking and other acts
of misconduct, earthquakes and similar events. Our postage processing systems
are located in Northern California, a seismically active region. We do not have
fully redundant systems, a formal disaster recovery plan or alternative
providers of hosting services, and we do not carry sufficient business
interruption insurance to compensate us for losses that may occur. Despite any
precautions we may take, problems or system failures at our third party hosted
facilities could result in interruptions in our service.

The inability to expand our systems capacity may limit our growth.

   Our inability to add additional software and hardware or to upgrade our
technology, transaction processing systems or network infrastructure to timely
accommodate increased Web site traffic or transaction volume could have adverse
consequences. These consequences include unanticipated system disruptions,
slower response times, degradation in levels of customer support and impaired
quality of the user's experience on our service and delays in reporting
accurate financial information. Our failure to provide new features or
functionality also could result in these consequences. We may be unable to
effectively upgrade and expand our systems in a timely manner or to integrate
smoothly any newly developed or purchased technologies with our existing
systems. These difficulties could harm or limit our ability to expand our
business.

We rely heavily upon third parties to deliver our Internet postage solution to
customers.

   We rely upon third parties to distribute and sell our Internet postage
solution. We cannot assure you that we will be able to develop and maintain
satisfactory relationships with such parties on acceptable commercial terms, if
at all, or that we will be able to obtain adequate distribution channels for
our solution. We are in discussions with a number of office supply and computer
retailers to carry our Internet postage solution and we cannot assure you that
these retailers will carry our solution or devote sufficient marketing, shelf
space or other resources to them. If we are unable to provide an adequate
distribution channel for our Internet postage solution, our business will be
seriously harmed. We depend upon the U.S. Postal Service and other delivery
services for the delivery of our secure postage device. Strikes or other
service interruptions affecting delivery services used by us would have a
material adverse effect on our ability to deliver our Internet postage solution
to our customers.

The postage market is highly competitive and we may be unable to compete
successfully against new entrants and established industry competitors with
significantly greater financial resources.

   The market for Internet postage products and services is new, rapidly
evolving and intensely competitive. We expect that our primary competitors will
include traditional providers of postage products and services, including
Pitney Bowes and Neopost, that have longer operating histories, larger customer
bases, greater brand recognition, greater financial, marketing, service,
support, technical, intellectual property and other resources than us. We will
also compete with providers of traditional postage products and delivery
services, such as the U.S. Postal Service, Federal Express and United Parcel
Service. In addition to providers of traditional postage products and services,
we compete with three other Information Based Indicia Program vendors, Neopost,
Pitney Bowes and Stamps.com, who have all initiated the certification process
with the U.S. Postal Service. Only one of these, Stamps.com, has been approved
for commercial release by the U.S. Postal Service to date. Many of our
competitors may be able to devote greater resources to marketing and
promotional campaigns, adopt more aggressive pricing policies and devote
substantially more resources to Web site and systems development than us. This
increased competition may result in reduced operating margins, loss of market
share and a diminished brand recognition.


                                       10

A breach of our online security would harm our business and reputation and
could interrupt service to our customers.

   A fundamental requirement to conduct electronic commerce is the secure
transmission of information over public networks. We rely on encryption and
authentication technology to provide the security necessary for transmission of
postage and other confidential information. Any breach of these security
measures would severely impact our business and reputation and would likely
result in the loss of customers. Furthermore, if we are unable to provide
adequate security, the U.S. Postal Service could prohibit us from selling
postage over the Internet. Advances in computer capabilities, new discoveries
in the field of cryptography, or other events or developments may result in a
compromise or breach of the algorithms we use to protect customer transaction
data. Security breaches could also expose us to a risk of loss or litigation
and possible liability for failing to secure confidential customer information.
Accordingly, we may be required to expend significant capital and other
resources to protect against potential security breaches or to alleviate
problems caused by any breach.

If we are unable to successfully protect our intellectual property, our
competitive position will be harmed.

   We rely on a combination of patent, trademark, service mark, copyright and
trade secret laws, contractual restrictions on disclosure and transferring
title and other methods in an effort to establish and protect proprietary
rights in our solutions, know-how and information. If our patents or other
intellectual property fail to protect our technology, our competitive position
could be harmed. In addition, third parties may develop alternative
technologies or products that do not infringe on any of our patents or other
intellectual property. We generally enter into confidentiality agreements with
our employees, consultants and other third parties to control and limit access
and disclosure of our proprietary information. These contractual arrangements
or other steps taken to protect our intellectual property may not be sufficient
to prevent misappropriation of technology or deter independent third party
development of similar technologies. Additionally, the laws of foreign
countries may not protect our solutions or intellectual property rights to the
same extent as do the laws of the United States.

Continued adoption of the Internet as a method of conducting business is
necessary for our future growth.

   The failure of the Internet to continue to develop as a medium for the
purchase of goods and services would adversely affect our business. Concerns
over the security of transactions conducted on the Internet and the privacy of
consumers may also inhibit the growth of the Internet and other online services
generally, and online commerce in particular. We cannot assure you that the
Internet will continue to be widely accepted and adopted for purchasing goods
and services.

Failure to expand Internet infrastructure could limit our future growth.

   The recent growth in Internet traffic has caused frequent periods of
decreased performance, and if Internet usage continues to grow rapidly, the
Internet's infrastructure may not be able to support these demands and its
performance and reliability may decline. If outages or delays on the Internet
occur frequently or increase in frequency, overall Web usage, including usage
of our Web site to purchase Internet postage, could grow more slowly or
decline. Our ability to increase the speed and scope of our services to users
is ultimately limited by and dependent upon the speed and reliability of the
Internet.

Our quarterly results are subject to significant fluctuations, and our stock
price may decline if we do not meet expectations of investors and analysts.

   Since the U.S. Postal Service's approval of our Internet postage solution in
August 1999, we have generated only nominal revenues from our operations.
Accordingly, we have little basis upon which to predict

                                       11
<PAGE>

future operating results. We expect that our revenues, margins and operating
results will fluctuate significantly due to a variety of factors, a number of
which are outside of our control. These factors include:

  .  the costs of our marketing programs to establish the E-Stamp brand name
     and generate market demand for our Internet postage solution;

  .  our ability to develop and maintain strategic and distribution
     relationships;

  .  timing of the commercial release of additional Internet postage
     solutions developed by us;

  .  the number, timing and significance of new solutions introduced by our
     competitors;

  .  the level of service and price competition;

  .  changes in our operating expenses as we expand operations; and

  .  general economic factors.

   A substantial portion of our operating expenses is related to personnel
costs, marketing programs and overhead, which cannot be adjusted quickly and
are therefore relatively fixed in the short term. Our operating expense levels
are based, in significant part, on our expectations of future revenues. If our
expenses precede increased revenues, both gross margins and results of
operations could be harmed because of increased costs and expenses in the short
term. Due to the foregoing factors and the other risks discussed in this
prospectus, you should not rely on period-to-period comparisons of our results
of operations as an indication of future performance. It is possible that in
some future periods our results of operations will be below the expectations of
public market analysts and investors. In this event, the market price of our
common stock is likely to fall.

We depend on key personnel and attracting qualified employees for our future
success.

   Our success depends to a significant degree upon the continued contributions
of our executive management team and other senior level financial, technical,
marketing and sales personnel. The loss of the services of these or other
members of our senior management team could have a material adverse effect on
our business and results of operations. We anticipate that the number of our
employees may increase significantly during the next 12 months as we increase
our research and development activities and sales and marketing efforts. Our
success depends upon our ability to attract and retain additional highly
qualified senior management and technical, sales and marketing personnel to
support planned growth of our operations. Competition for qualified employees
is intense, particularly in the Internet and high technology industries. The
process of locating and hiring personnel with the combination of skills and
attributes required to carry out our strategy is time-consuming and costly. The
loss of key personnel or our inability to attract additional qualified
personnel to supplement or, if necessary, to replace existing personnel, could
have a material adverse effect on our business and results of operations.

Rapid technological change may make our Internet postage solution obsolete or
cause us to incur substantial costs to adapt to these changes.

   The use of the Internet for the purchase and sale of goods and services is
characterized by rapidly changing technology, evolving industry standards and
frequent new product announcements. To be successful, we must adapt to these
rapid changes by continually improving the performance, features and
reliability of our products and services, and to develop new solutions, or else
our products and services may become noncompetitive or obsolete. We also could
incur substantial costs to modify our solutions or infrastructure and to
develop new solutions, in order to adapt to these changes. Our business,
operating results and financial condition could be harmed if we incur
significant costs without adequate results, or find ourselves unable to adapt
rapidly to these changes.


                                       12
<PAGE>

We may be unable to effectively manage any future acquisitions of new or
complementary businesses, products or technology.

   We may pursue the acquisition of new or complementary businesses, including
individual products or technologies, in an effort to enter into new markets,
diversify our sources of revenue and expand our solutions. At present, we have
no commitments or agreements and are not currently engaged in discussions for
any material acquisitions or investments. To the extent we pursue new or
complementary businesses, we may not be able to expand our solutions and
related operations in a cost-effective or timely manner. We may experience
increased costs, delays and diversions of management's attention when
integrating any new businesses. We may lose key personnel from our operations
or those of any acquired business. Furthermore, any new business or solution we
launch that is not favorably received by users could damage our reputation and
brand name. We also cannot be certain that we will generate satisfactory
revenues from any expanded solutions to offset related costs. Any expansion of
our operations would also require significant additional expenses, and these
efforts may strain our management, financial and operational resources.
Additionally, future acquisitions may also result in potentially dilutive
issuances of equity securities, the incurrence of additional debt, the
assumption of known and unknown liabilities, and the amortization of expenses
related to goodwill and other intangible assets, all of which could harm our
business, financial condition and operating results.

Internet postage cannot currently be used internationally which may limit our
future growth.

   At present, Internet postage approved by the U.S. Postal Service can only be
used to send mail from one United States address to another. While we believe
that Internet postage solutions such as ours could be of benefit to customers
in foreign countries or to send mail from the United States to foreign
countries, unless and until foreign postal authorities create a certification
process and recognize information-based indicia postage, our Internet postage
solution will not be able to address these markets which may limit our future
growth. Efforts in Europe and other foreign markets related to adoption of
Internet postage are at a very preliminary stage. We cannot assure you that
foreign postal authorities will adopt policies and processes for Internet
postage that are compatible with those approved by the U.S. Postal Service on a
timely basis or at all.

If we market our solutions internationally, regulation by international
agencies could disrupt our operations.

   If foreign postal authorities in the future accept postage generated by our
solutions and if we obtain the necessary foreign certification or approvals, we
would be subject to ongoing regulation by international governments and
agencies. If we achieve significant international acceptance of our solutions,
our business activities will be subject to a variety of potential risks,
including the adoption of laws and regulatory requirements, political and
economic conditions, difficulties protecting our intellectual property rights
and actions by third parties that would restrict or eliminate our ability to do
business in certain jurisdictions. If we begin to transact business in foreign
currencies, we will become subject to the risks attendant to transacting in
foreign currencies, including the potential adverse effects of exchange rate
fluctuations.

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

   Failure of our internal computer systems or third-party equipment or
software, or systems maintained by our users and strategic sales and marketing
partners, to operate properly with regard to the Year 2000 issues could require
us to incur significant unanticipated expenses to remedy any problems and could
cause system interruptions and loss of data. Any of these events could harm our
reputation and materially and adversely affect our business. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--Year
2000 Compliance."

We may need additional capital and failure to obtain such capital could harm
our business.

   We require substantial working capital to fund our business. We cannot be
certain that additional financing will be available to us on favorable terms
when required, or at all. Since our inception, we have experienced negative
cash flow from operations and expect to experience significant negative cash
flow from operations in the future. We currently anticipate that the net
proceeds of this offering, together with our available funds, will be
sufficient to meet our anticipated needs for working capital and capital
expenditures through at least the next 12 months. The estimate of the time
period during which these proceeds will be sufficient is a forward-looking
statement that is subject to risks and uncertainties. Our actual funding
requirements may differ materially from this as a result of the number of
factors, including our plans to fully support the commercial release and
support of our Internet postage solution, our development and introduction of
new solutions and our investments in expanding our systems infrastructure and
staffing. We may need to raise additional funds prior to the end of the next 12
months or at a later date.

Regulatory and legal uncertainties could harm our business.

   A number of laws and regulations may be adopted with respect to the Internet
relating to user privacy, pricing, content, copyrights, distribution, and
characteristics and quality of products and services that could adversely
affect adoption of the Internet for electronic commerce solutions. A decline in
the growth of the Internet could decrease demand for our solutions and increase
our cost of doing business. Moreover, the applicability of existing laws to the
Internet is uncertain with regard to many issues such as property ownership,
export of encryption technology, sales tax, libel and personal privacy. The
application of laws and regulations from jurisdictions whose laws do not
currently apply to our business or the application of existing laws and
regulations to the Internet and other online services could also harm our
business.

Shares eligible for future sale by our existing stockholders may adversely
affect our stock price.

   If our stockholders sell substantial amounts of our common stock, including
shares issued upon the exercise of outstanding options, in the public market
following this offering, the market price of our common stock could fall. In
addition, such sales could create the perception to the public of difficulties
or problems with our products and services. As a result, these sales also might
make it more difficult for us to sell equity or equity-related securities in
the future at a time and price that we deem appropriate.

   Upon completion of this offering, we will have outstanding          shares
of common stock, assuming no exercise of the underwriters' over-allotment
option and no exercise of outstanding options after June 30, 1999. Of these
shares, the shares sold in this offering are freely tradable. The remaining
         shares will become eligible for sale in the public market as follows:

We have broad discretion to use the proceeds from this offering and may not use
the proceeds effectively.

   The majority of the net proceeds of this offering are not allocated for
specific uses other than working capital and general corporate purposes. Thus,
our management has broad discretion over how these proceeds are used and could
spend most of these proceeds in ways with which our stockholders may not agree.
We cannot assure you that the proceeds will be invested in a way that yields a
favorable return.

Our securities have no prior market and our stock price may decline after the
offering.

   Before this offering, there has not been a public market for our common
stock and an active public market for our common stock may not develop or be
sustained after this offering. The initial public offering price has been
determined by negotiations between E-Stamp and the representatives of the
underwriters, and we cannot assure you that the trading market price of our
common stock will not decline below the initial public offering price.

Internet related stock prices are especially volatile and this volatility could
cause our stock price to fluctuate dramatically which could result in
substantial losses to investors.

   The stock market and specifically the stock of Internet related companies
have been very volatile. This broad market volatility and industry volatility
may reduce the price of our common stock, without regard to our operating
performance. In particular, following initial public offerings, the market
prices for stock of Internet related companies often reach levels that bear no
relation to the operating performance of these companies. The market prices are
generally not sustainable and could vary widely. If our common stock trades to
high levels following this offering, it could eventually experience a
significant decline.

You should not rely on forward-looking statements because they are inherently
uncertain.

   This prospectus contains forward-looking statements that involve risks and
uncertainties. We use words such as "anticipates," "believes," "plans,"
"expects," "future," "intends" and similar expressions to identify such
forward-looking statements. This prospectus also contains forward-looking
statements attributed to certain third parties relating to their estimates
regarding the growth of Internet usage, business-to-business, business-to-
consumer electronic commerce, postage usage, small office-home offices and
related service markets and spending. You should not place undue reliance on
these forward-looking statements. Our actual results could differ materially
from those anticipated in these forward-looking statements for many reasons,
including the risks faced by us described above and elsewhere in this
prospectus.

                                USE OF PROCEEDS

   Our net proceeds from the sale of the          shares of common stock
offered hereby are estimated to be $        , based on an assumed initial
public offering price of $           per share and after deducting the
underwriting discount and estimated offering expenses. If the underwriters'
over-allotment option is exercised in full, our net proceeds will be
approximately $          .

   We expect to use the net proceeds for sales and marketing expenditures
related to promoting our Internet postage solution, building E-Stamp brand
recognition, and developing additional strategic relationships, with the
balance for general corporate purposes, including working capital and expansion
of our corporate infrastructure. In addition, we may use a portion of the net
proceeds to acquire complementary products, technologies or businesses;
however, we currently have no commitments or agreements and are not involved in
any negotiations to do so. Pending use of the net proceeds of this offering, we
intend to invest the funds in short-term, interest-bearing, investment-grade
securities.

and expansion of our business and do not anticipate paying any cash dividends
in the foreseeable future.

                                    DILUTION

   The pro forma net tangible book value of our common stock on June 30, 1999
(after giving effect to the conversion of all outstanding shares of our
convertible preferred stock, our sale of 2,931,229 shares of convertible
preferred stock in August 1999 for an aggregate purchase price of approximately
$30.2 million) was $        , or approximately $      per share. Pro forma net
tangible book value per share represents the amount of our total tangible
assets less total liabilities, divided by the number of shares of common stock
outstanding. Dilution in net tangible book value per share represents the
difference between the amount per share paid by purchasers of shares of our
common stock in this offering and the net tangible book value per share of our
common stock immediately afterwards. After giving effect to our sale of
         shares of common stock offered by this prospectus at an assumed
initial public offering price of $        per share and after deducting the
underwriting discount and estimated offering expenses payable by us, our net
tangible book value would have been approximately $        , or $       per
share. This represents an immediate increase in net tangible book value of
$       per share to existing stockholders and an immediate dilution in net
tangible book value of $       per share to new investors purchasing shares of
common stock in this offering. The following table illustrates this dilution.

</TABLE>

   This table excludes all options and warrants that will remain outstanding
upon completion of this offering. As of June 30, 1999, there were options
outstanding to purchase a total of 1,029,000 shares of common stock with an
average exercise price of $0.90 per share. See Notes 3 and 9 of Notes to
Financial Statements. The exercise of outstanding options and warrants having
an exercise price less than the offering price would increase the dilutive
effect to new investors.

   The following table sets forth, as of June 30, 1999, on the pro forma basis
described above, the differences between the number of shares of common stock
purchased from us, the total price paid and average price per share paid by
existing stockholders and by the new investors in this offering at an assumed
initial public offering price of $      per share (before deducting the
underwriting discount and estimated offering expenses payable by us).

   If the underwriters over-allotment option is exercised in full, the

    decrease to          or approximately      % of the total number of
    shares of our common stock outstanding after this offering, and

  . the number of shares held by new public investors will increase to

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

   This prospectus contains forward-looking statements that involve risks and
uncertainties. Our actual results could differ materially from those
anticipated in forward-looking statements for many reasons, including the risks
described in "Risk Factors" and elsewhere in this prospectus. You should read
the following discussion with the "Selected Financial Data" and our financial
statements and related notes included elsewhere in this prospectus.

Overview

   We provide an easy-to-use Internet postage solution that enables users to
purchase, download and print Internet postage directly from their personal
computers. We pioneered the development of Internet postage, including being
one of the first companies to approach the U.S. Postal Service with the idea of
printing postage from a personal computer. From November 1994 to March 1998, we
incurred operating costs primarily related to the development of our Internet
postage solution in accordance with U.S. Postal Service guidelines and
specified criteria. In March 1998, after extensive development and interaction
with the U.S. Postal Service, we began the three-phase beta test certification
process required by the U.S. Postal Service to qualify Internet postage vendors
for commercial distribution of Internet postage under the U.S. Postal Service's
Information Based Indicia Program. In August 1999, we received final approval
from the U.S. Postal Service for our Internet postage solution and since then
have been selling our solution nationally in accordance with approved
quantities and distribution channels.

   In addition to working with the U.S. Postal Service to obtain approval of
our Internet postage solution, our primary activities since inception have
included:

  . developing our business model;

  . developing and testing our Internet postage solution;

  . hiring management and other key personnel;

  . building our infrastructure; and

  . entering into strategic alliances.

   Subsequent to June 30, 1999, we have recognized only nominal revenues from
our desktop Internet postage solution. We intend to recognize revenue from an
initial license fee for our Internet postage solution, ongoing convenience fees
for the purchase of postage on the Internet, and the sale of ancillary postage
supplies. Our costs of revenues include the costs of manuals, packaging, the
postage device, credit card and electronic funds transfer fees, the address
management system, support costs, as well as fulfillment costs, and direct
costs from the sale of postage supplies.

   The revenue and income potential of our business and market is unproven, and
our limited operating history makes it difficult to evaluate our prospects. We
have incurred net losses in each quarterly and annual period since our
inception, and as of June 30, 1999, our accumulated deficit was $37.0 million.

   During the years ended December 31, 1996, 1997 and 1998 and the six months
ended June 30, 1999, in connection with the grant of certain stock options to
employees, we recorded deferred stock compensation totaling $12.8 million,
representing the difference between the deemed fair value of our common stock
on the date such options were granted and the exercise price. Such amount is
included as a reduction of stockholders' equity and is being amortized over the
vesting period of the individual options, generally four years, using the
graded vesting method. We recorded amortization of deferred stock compensation
in the amount of $688,000, $414,000 and $405,000 for the years ended December
31, 1996, 1997 and 1998 and $1.9 million for the six months ended June 30,
1999. At June 30, 1999, we had a total of $9.3 million remaining to be
amortized over the corresponding vesting periods of the stock options. We
anticipate that additional deferred compensation will be recorded for options
granted in July and August 1999. See Notes 3 and 9 of Notes to Financial
Statements.

Results of Operations

 Six Months Ended June 30, 1999 Compared to Six Months Ended June 30, 1998

   Research and Development. Research and development expenses include expenses
for research, design and development of our Internet postage solution, expenses
related to obtaining patents from the U.S. Patent Office, and server and
network operations. Research and development expenses increased 113% to $5.2
million for the six months ended June 30, 1999 from $2.5 million for the
six months ended June 30, 1998. The increase in research and development
expenses was due primarily to increases in employee headcount, consulting
costs, contractor expenses and project materials due to further development of
our Internet postage solution, server-based solution, operations network
investments and costs of product shipped to customers during the beta test
portion of the U.S. Postal Service approval process. We expect the dollar
amount of research and development expenses to increase in future periods to
support further development of our Internet postage solution and our server-
based solution and expenses related to the development of other products and
services.

   Sales and Marketing. Sales and marketing expenses consist primarily of
salaries and related benefits for sales and marketing personnel, Web site
development, package design, advertising and promotional expenses, and trade
show expenses. Sales and marketing expenses increased 119% to $2.5 million for
the six months ended June 30, 1999 from $1.1 million for the six months ended
June 30, 1998. The increase in sales and marketing expenses was due primarily
to expenses related to growth in the number of strategic relationships,
expenses related to the anticipated launch of our Internet postage solution,
costs related to the continued development of our marketing campaigns, and an
increase in sales and marketing personnel. We expect sales and marketing
expenses to increase in dollar amount as we promote and launch our Internet
postage solution and as we hire additional personnel, continue to promote our
brand and add new strategic relationships.

   General and Administrative. General and administrative expenses consist
primarily of compensation for administrative and executive staff, fees for
professional services, depreciation expense and general office expenses.
General and administrative expenses increased 52% to $1.4 million for the six
months ended June 30, 1999 from $903,000 for the six months ended June 30,
1998. The increase in general and administrative expenses was due primarily to
a one-time charge for severance accrual for a former executive officer and, to
a lesser extent, an increase in administrative staff and professional fees. We
expect general and administrative expenses to increase in dollar amount due to
further additions in staffing and as we incur additional costs necessary to
prepare and manage the infrastructure for business expansion, for legal
services in connection with the Pitney Bowes litigation, and associated with
being a public reporting company.

   Amortization of Deferred Compensation. Amortization of deferred stock
compensation was $1.9 million for the six months ended June 30, 1999. There was
no amortization of deferred stock compensation for the six months ended June
30, 1998. We recorded aggregate deferred stock compensation of $11.6 million in
the period from July 1, 1998 through June 30, 1999 for options awarded to
employees with exercise prices below the deemed fair value for financial
reporting purposes of our common stock on their respective grant dates.

   Interest Income, Net. Interest income, net, consists primarily of earnings
on our cash and cash equivalents, net of interest expenses attributable to
equipment leases and any taxes. Interest income, net, increased 309% to
$176,000 for the six months ended June 30, 1999 from $43,000 for the six months
ended June 30, 1998. The increase in interest income, net, was due to
increasing average cash and cash equivalent balances as we received funds from
our financing activities. We expect interest income, net, to increase following
this offering as a result of increased cash balances resulting from this
offering.

 Year Ended December 31, 1998 Compared to Years Ended December 31, 1997 and
 1996

   Research and Development. Research and development expenses increased 43% to
$5.6 million in 1998 from $3.9 million in 1997 and increased 64% in 1997 from
$2.4 million in 1996. The increases in research and development expenses in
1998 and 1997 were due primarily to increases in employee headcount, contractor
expenses, project materials and network operations investments.

                                       21
<PAGE>

   Sales and Marketing. Sales and marketing expenses increased 56% to $2.7
million in 1998 from $1.7 million in 1997 and decreased 1% in 1997 from $1.8
million in 1996. The increase in sales and marketing expenses in 1998 was due
primarily to an increase in sales and marketing personnel, costs related to the
continued development of our marketing and branding campaigns, expenses related
to the anticipated launch of our Internet postage solution, and expenses
related to growth in the number of strategic relationships. Sales and marketing
expenses in 1997 decreased modestly due to a reduction in trade show activity.

   General and Administrative. General and administrative expenses increased 9%
to $1.9 million in 1998 from $1.7 million in 1997 and increased 1% in 1997 from
$1.7 million in 1996. The increase in general and administrative expenses in
1998 was due primarily to increases in administrative staff, rent, professional
services and general office expenses. General and administrative expenses in
1997 increased modestly due to a small increase in administrative staff.

   Amortization of Deferred Stock Compensation. Amortization of deferred stock
compensation decreased 2% to $405,000 in 1998 from $414,000 in 1997 and
decreased 40% in 1997 from $688,000 in 1996. In 1996, we recorded deferred
stock compensation of approximately $1.1 million related to equity awards to
employees. We also recorded aggregate deferred stock compensation of
approximately $2.7 million in 1998 for options awarded to employees with
exercise prices below the deemed fair value for financial reporting purposes of
our common stock on their respective grant dates.

   Interest Income, Net. Interest income, net, increased 159% to $370,000 in
1998 from $143,000 in 1997 and decreased 39% in 1997 from $236,000 in 1996. The
increase in interest income, net, in 1998 was due to increasing average cash
and cash equivalent balances as we received funds from our financing activities
in 1998. The decrease in interest income, net, in 1997 was due to declining
average cash and cash equivalent balances as we spent funds that had been
received.

Liquidity and Capital Resources

   Since inception, we have financed our operations primarily through private
sales of equity securities. We have received approximately $68.9 million in
private funding, including $30.2 million through our most recent financing in
August 1999. In addition, we have a $1.25 million line of credit with a bank,
all of which is available for use by us except for a $143,000 letter of credit
to secure our lease and capital lease obligations totaling $26,000 as of June
30, 1999.

   Net cash used in operating activities totaled $7.9 million for the six
months ended June 30, 1999, $9.6 million for the year ended December 31, 1998,
$5.7 million for the year ended December 31, 1997, and $4.9 million for the
year ended December 31, 1996. Cash used in operating activities for each period
resulted primarily from net operating losses in those periods.

   Net cash provided by (used in) investing activities totaled $(387,000) for
the six months ended June 30, 1999, $(324,000) for the year ended December 31,
1998, $(21,000) for the year ended December 31, 1997, and $202,000 for the year
ended December 31, 1996. Cash provided by (used in) investing activities for
each period resulted primarily from the acquisition of capital assets,
primarily computer and office equipment.

   Net cash provided by financing activities totaled $12,000 for the six months
ended June 30, 1999, $16.0 million for the year ended December 31, 1998, $5.9
million for the year ended December 31, 1997, and $8.4 million for the year
ended December 31, 1996. Cash provided by financing activities for each period
resulted primarily from issuances of common stock and redeemable convertible
preferred stock, offset by the repayment of lease obligations and notes payable
to related parties.

   We believe that the net proceeds from this offering, together with our
current cash balances and cash flows from operations, if any, will be
sufficient to meet our present growth strategies and related working capital
and capital expenditure requirements for at least the next 12 months. Our
forecast of the period of time through

                                       22
<PAGE>

which our financial resources will be adequate to support operations is a
forward-looking statement that involves risks and uncertainties. Our actual
funding requirements may differ materially from this as a result of a number of
factors including our plans to fully support the commercial release of our
desktop Internet postage solution, our introduction of new solutions and our
investments in systems infrastructure and staffing. We may require substantial
working capital to fund our business and we may need to raise additional
capital prior to this time or thereafter. We cannot be certain that additional
funds will be available on satisfactory terms when needed, if at all. If we are
unable to raise additional necessary capital in the future, we may be required
to curtail our operations significantly. Also, raising additional equity
capital would have a dilutive effect on existing stockholders.

   We believe that our exposure to market risk related to changes in interest
rates, equity prices and foreign currency exchange rates is not material. At
June 30, 1999, we did not hold any short or long-term investments.

Year 2000 Compliance

   Background. Many currently installed computer systems, software products and
other control devices are unable to accept four digit entries to distinguish
21st century dates from 20th century dates. As a result, many companies'
computer systems, software products and control devices may need to be upgraded
or replaced in order to operate properly in the year 2000 and beyond.

   Assessment and Implementation. The U.S. Postal Service requires participants
in the Information Based Indicia Program to maintain Year 2000 compliant
systems and software. As a result, we are in the process of developing a
comprehensive plan to make our internal computer software and hardware systems
Year 2000 compliant. Our Year 2000 compliance plan is comprised of 3 phases: an
assessment phase; an implementation phase; and a testing phase. This plan,
initiated in the first quarter of fiscal 1999, will be implemented by the end
of the fourth quarter of fiscal 1999. While we believe that this plan for
addressing the Year 2000 problem will be completed in a timely manner, we
cannot be certain that these Year 2000 compliance efforts will be successful.
The financial impact of making the required systems changes cannot be known
precisely at this time, but we currently expect these expenses to be less than
approximately $500,000. The financial impact, could, however, exceed this
estimate. Nonetheless, these costs are not expected to be material to our
business, financial condition, or results of operation. To date, we have
incurred expenses of less than approximately $100,000.

   Since inception, we have internally developed substantially all of the
systems for the operation of our Internet postage solution. These systems
include the software used to provide customer interaction and transactional and
distribution functions to our solutions, as well as monitoring and back-up
capabilities. Based upon our assessment to date, we believe that our systems
will be Year 2000 compliant and have submitted Year 2000 readiness statements
to the U.S. Postal Service to indicate our Year 2000 compliance. However, we
cannot be sure how our Internet postage solution will integrate with other
vendor-provided software.

   We use and depend on third-party equipment and software that may not be Year
2000 compliant. Consequently, our ability to address Year 2000 issues is, to a
large extent, dependent upon the Year 2000 readiness of these third parties'
hardware and software products. We are currently assessing the Year 2000
readiness of other third-party supplied software, computer technology and other
services. We have initiated communications or obtained information from our
vendors and suppliers of third-party equipment and software to validate that
their products and systems are Year 2000 compliant. Based on the
representations that we have received and obtained from our third party vendors
and suppliers, we believe that their systems are Year 2000 compliant. We will
develop and implement, if necessary, a remediation plan with respect to third-
party software, third-party vendors and computer technology and services that
may fail to be Year 2000 compliant.

   If Year 2000 issues prevent our users from accessing the Internet or our
Internet postage solution or from processing postage, our business and
operations will suffer. Any failure of our third-party equipment or software to
operate properly could require us to incur unanticipated expenses, which could
seriously harm our business, operating results and financial condition. For
example, pursuant to regulations of the Information

                                       23
<PAGE>

Based Indicia Program, we rely on the U.S. Postal Service's secure postage
accounting vault to purchase postage credit for our customers. If the
U.S. Postal Service systems are not Year 2000 compliant, our users may not be
able to purchase additional postage.

   The Year 2000 readiness of the Internet infrastructure necessary to support
our operations is difficult to assess. For instance, we depend upon the
integrity and stability of the Internet to provide our services. We also depend
on the Year 2000 compliance of the computer systems and financial services used
by our customers. Thus, the infrastructure necessary to support our operations
consists of a network of computers and telecommunications systems located
throughout the world and operated by numerous unrelated entities and
individuals, none of which has the ability to control or manage the potential
Year 2000 issues that may impact the entire infrastructure. Our ability to
assess the reliability of this infrastructure is limited and relies solely on
generally available news reports, surveys and comparable industry data. Based
on these sources, we believe most individuals that rely significantly on the
Internet are carefully reviewing and attempting to remediate issues relating to
Year 2000 compliance, but it is not possible to predict whether these efforts
will be successful in reducing or eliminating the potential negative impact of
Year 2000 issues. A significant disruption in the ability of customers to
reliably access the Internet would have an adverse effect on demand for our
solutions and would harm our results of operations.

   Contingency Planning. We are currently developing contingency plans to be
implemented as part of our efforts to identify and correct Year 2000 problems
affecting our internal systems. We expect to complete these contingency plans
by the end of the third quarter of 1999. Depending on the systems affected,
these plans could include (1) accelerated replacement of effected equipment or
software, (2) increase work hours for our personnel or use of contract
personnel to correct on an accelerated schedule any Year 2000 problems which
may arise, (3) the provision of manual workarounds for information systems and
(4) other similar approaches. If we are required to implement any of these
contingency plans, such plans may have a material adverse effect on our
business, financial condition or results of operations. Additionally, we may
not complete these contingency plans in a timely manner, and failure to do so
could have a material adverse effect on our business, financial condition or
results and operations.

   The discussion of our efforts and expectations relating to Year 2000
compliance are forward-looking statements that are subject to risks and
uncertainties and actual results may differ materially from those indicated in
these forward-looking statements. Our ability to achieve Year 2000 compliance
and the level of anticipated expenses related to Year 2000 compliance could be
adversely affected by, among other things, the availability and cost of testing
and programming resources, the ability of third parties to resolve Year 2000
issues associated with their systems and software and unanticipated problems
that may in the future be identified in our ongoing compliance review.

Recent Accounting Pronouncements

   Effective January 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130, "Reporting for Comprehensive Income." Statement
of Financial Accounting Standards No. 130 requires disclosures of components of
non-stockholder changes in equity in interim periods and additional disclosures
of components of non-stockholder changes in equity on an annual basis. Adoption
of Statement of Financial Accounting Standards No. 130 had no impact on the
Company's results of operations or financial position.

   In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting No. 131, "Disclosures about Segments of an Enterprise and
Related Information." The Company adopted Statement of Financial Accounting No.
131 effective January 1, 1998. The adoption of this standard did not have a
material effect on the Company's financial statement disclosures as the Company
operates in a single segment.

   In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities." The Company is required to adopt Statement of
Financial Accounting Standards No. 133 for the year ending December 31, 2000.
Statement of Financial Accounting Standards No. 133 establishes methods of
accounting for derivative

                                       24
<PAGE>

financial instruments and hedging activities related to those instruments as
well as other hedging activities. Because the Company currently holds no
derivative financial instruments and does not currently engage in hedging
activities, adoption of Statement of Financial Accounting Standards No. 133 is
expected to have no material impact on the Company's financial condition or
results of operations.

   In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-1, "Accounting for the Cost of Computer Software
Developed or Obtained for Internal Use." Statement of Position 98-1 is
effective for financial statements for years beginning after December 15, 1998.
Statement of Position 98-1 provides guidance over accounting for computer
software developed or obtained for internal use including the requirement to
capitalize specified costs and amortization of such costs. We adopted the
provisions of Statement of Position 98-1 on January 1, 1999. The adoption of
Statement of Position 98-1 has not had a material impact on our financial
position or results of operations.

Quantitative and Qualitative Disclosures About Market Risk

   Our interest income and expense are sensitive to changes in the general
level of interest rates. In this regard, changes in interest rates affect the
interest on our cash equivalents earned as well as the interest incurred on our
indebtedness. Based on our cash equivalents balance and level of indebtedness
at June 30, 1999, our exposure to interest rate risk is not material.

 Overview

   We provide an easy-to-use Internet postage solution that enables users to
purchase, download and print postage directly from their personal computers.
The postage can be printed directly onto envelopes, labels or documents using
standard laser or inkjet printers, 24 hours a day, seven days a week, without
the need to remain connected to the Internet. We received approval from the
U.S. Postal Service in August 1999 for our Internet postage solution, and since
then have been selling our solution nationally. We are targeting our Internet
postage solution at small business, small office and home office users,
collectively known as SOHO users. To help build our brand awareness and
accelerate the adoption of our Internet postage solution, we have formed
strategic relationships with industry leaders, such as Microsoft, Yahoo!,
Excite@Home, America Online, Compaq, Earthlink, Francotyp-Postalia and Avery
Dennison. We believe our cost-effective Internet postage solution will enhance
customer satisfaction during the mail and postage process by improving overall
access, convenience and flexibility for SOHO users, in addition to increasing
operating efficiencies and decreasing postal fraud for the U.S. Postal Service.

Industry Background

 The Internet and Electronic Commerce

   The Internet has emerged as a global medium for communications, information
and commerce. With over 125 million users at the end of 1998, which is expected
to grow to approximately 500 million users by 2003, as estimated by
International Data Corporation, the Internet is dramatically changing how
businesses and other users communicate and share information. The Internet has
also created new opportunities to conduct commerce, including business-to-
business electronic commerce, which enables organizations to streamline
business processes, lower operating costs and improve productivity. According
to Forrester Research, business-to-business electronic commerce is expected to
grow from an estimated $43 billion in 1998 to approximately $1.3 trillion in
2003, accounting for more than 90% of the dollar value of electronic commerce
in the United States. Due to the Internet's convenience and accessability,
businesses are increasingly using the Internet for a wide variety of
operations, such as buying office supplies online, and may benefit from
emerging trends, such as buying postage over the Internet.

 The Postage Industry

   According to the U.S. Postal Service's latest annual report, the total
postage market in the U.S. was approximately $60 billion in 1998. Further, the
U.S. Postal Service processed over 197 billion pieces of mail, or an estimated
41% of the total worldwide mail shipments. Of the $60 billion U.S. postage
market, approximately $38 billion was represented by postage stamps and postage
meters, which are primarily used for first class, priority and express mail,
with the remaining $22 billion consisting of permit and other mail services.
Keenan Vision, an independent research firm, estimates that first class,
priority and express mail usage will grow to approximately $46 billion by the
year 2002. In addition, the worldwide private market for mail and parcel
delivery which does not require postage from governmental entities includes
services such as Federal Express and United Parcel Service.

   The U.S. Postal Service's longstanding mission is to meet the needs of its
customers with convenient options and improved postage security. To enhance
customer satisfaction, we believe the U.S. Postal Service searches for
innovations that:

  .  provide postal services that are convenient, cost-effective and easy-to-
     use;

  .  leverage existing customer infrastructures, such as personal computers,
     printers and software, to provide better and more efficient products and
     services;


                                       26
<PAGE>

  .  integrate mailing information on the computer desktop, including postage
     accounting;

  .  improve access to the large and growing small business, small office and
     home office markets, collectively known as the SOHO market;

  .  reduce the occurrence of postal fraud, which costs in excess of $150
     million per year in lost revenues according to the U.S. General
     Accounting Office; and

  .  increase efficiencies in the handling and processing of mail, thereby
     expediting the mailing process and enabling the U.S. Postal Service to
     lower its operating costs.

 The Emergence of Internet Postage

   To address these objectives, the U.S. Postal Service announced in 1995 a
program for its first new postage method since the approval of the postage
meter in 1920. The Information Based Indicia Program is a certification program
that authorizes third party vendors to sell digital postage that users purchase
over the Internet and print from a personal computer using ordinary laser or
inkjet printers. Internet postage consists of a two dimensional bar code
containing an encrypted digital signature that makes each digital stamp unique
and is intended to lower the prevalence of postal fraud. Through its
Information Based Indicia Program, the U.S. Postal Service is seeking to
enhance user convenience with a new access channel for postage that enables
users to print postage from a personal computer, 24 hours a day, seven days a
week.

   The following illustration is an example of our Internet postage that
conforms to the Information Based Indicia Program requirements, along with an
explanation of what each part represents.

 The Growth of SOHOs and Their Postage and Internet Usage

   The United States has a large and growing number of small businesses, small
offices and home offices, collectively known as SOHOs. According to
International Data Corporation, there were 44.7 million SOHOs in the U.S. in
1998, which is expected to grow to 57.6 million by 2002. Of the 44.7 million
SOHOs in 1998, International Data Corporation estimates that 37.3 million were
home offices, 5.7 million were small businesses with less than ten employees
and 1.7 million were small businesses with more than ten employees. Further,
International Data Corporation estimates that SOHOs accounted for $3.7 billion
of electronic commerce in 1998 and will account for $69.7 billion of electronic
commerce in 2002. In addition, SOHOs are typically identified with the
following characteristics:

  .  limited amount of time and resources, resulting in the desire for
     solutions that simplify business processes; and

  .  self sufficient and "do-it-yourself" entrepreneurs who are willing to
     adopt new technologies that save time and increase flexibility.

   Postage Usage. SOHOs generally conduct an essential part of their
communications with suppliers and customers through the postal system,
including letters and packages that require expedited delivery. Despite the
relative importance of postage usage, SOHO use of postage meters is low, and it
appears that using a postage meter is not cost-effective for their needs. Based
on a 1999 survey from International Data Corporation, 80% of small
business/small office with 10 employees or less did not use a postage meter.
When the total cost is computed, including lease fees for both the postage
meter and scale, which approximate $25 per month, postage meter resetting fees
and proprietary consumables such as ink cartridges, which approximate another
$25 per month, SOHOs pay a significant premium to traditional postage stamps.
In addition, leasing a postage meter typically has required a multi-year lease
lock-in period.


   Internet Usage. As the Internet helps simplify business processes, SOHOs
have become more willing to rely on its functionality to improve their
businesses. Accordingly, there has been increased adoption of the Internet by
SOHOs, as the following statistics indicate:

  .  International Data Corporation estimates that 56% of U.S. home offices
     in 1998 had Internet access, and that this percentage will reach 72% by
     2002; and

  .  for U.S. small businesses, International Data Corporation estimates that
     approximately 50% had Internet access in 1998. This amount is expected
     to increase to 67% by 2002.

   Despite the increasing prevalence of Internet access, most SOHOs are
constrained by limited bandwidth Internet connections. Currently, International
Data Corporation estimates that:

  .  approximately 80% of SOHOs with Internet access use dial-up modems,
     usually at 28.8 or 33.6 kilobytes per second, to connect to the
     Internet;

  .  only 2.2% of SOHOs with Internet access use a broadband connection,
     which provides faster access but the availability of which is limited;
     and

  .  approximately 71% of SOHOs share their modem lines with another device
     such as a telephone or fax machine, which necessitates being connected
     to the Internet only when performing required business functions.

   Given the rapid adoption of the Internet and the high postage usage by
SOHOs, a substantial opportunity exists to provide an automated method for
purchasing, downloading and printing postage. We believe the attractiveness of
Internet postage solutions for the SOHO user will depend upon the solution's
ability to:

  .  enhance accessibility to postage, at any time of day;

  .  eliminate the costly time spent travelling to and waiting at the post
     office;

  .  automate business processes through integration with existing business
     software programs;

                                       28

  .  be easy to use and flexible to meet the SOHO user's preferences;

  .  enable the tracking and reporting of postage usage;

  .  provide cost savings and faster mail delivery versus traditional postage
     solutions; and

  .  leverage a user's existing investment in personal computers, printers
     and software.

The E-Stamp Solution

   We provide an easy-to-use Internet postage solution that enables our
customers to quickly and efficiently purchase and download postage over the
Internet directly into a secure, silver-dollar size postage device, and then to
print the purchased postage from their personal computers at any time without
the need to remain connected to the Internet. We have leveraged our customer-
centric focus and over 20 issued patents to create a solution that offers
convenience and flexibility to small business, small office and home office
users, collectively known as SOHO users. To help build our brand awareness and
accelerate the adoption of our Internet postage solution, we have formed
strategic relationships with industry leaders. In addition, our Internet
postage solution is tightly integrated with popular business computer programs,
including Microsoft Word and Outlook, and Intuit's Quickbooks.

   We believe our desktop Internet postage solution provides the following
benefits to SOHO users and the U.S. Postal Service:

 Benefits to SOHO Users

   Enhanced Flexibility. With our Internet postage solution, SOHO users receive
the benefits of buying and downloading postage online, with the flexibility of
printing postage while connected or disconnected from the Internet. Our
solution is tailored to most SOHO users, who are unable to, or desire not to,
stay continuously connected to the Internet due to shared connections and
access via slow dial-up modems;

   Convenient Access. Our Internet postage solution provides unlimited,
convenient access to postage from the computer desktop, 24 hours a day, seven
days a week. SOHO users can purchase, download and print postage with their
personal computer, thereby avoiding common inconveniences such as running out
of postage and waiting in long lines at the post office;

   Tight Integration. Our Internet postage solution is tightly integrated with
popular software applications, including Microsoft Word and Outlook, to enable
SOHO users to conveniently print postage while using their most commonly used
software programs;

   Variety of Postage Options. Our Internet postage solution enables SOHO users
to print professional looking addresses and postage on envelopes, labels or
directly on correspondence in one easy step, with the postage printed in any
denomination. Further, our solution enables SOHO users to print a variety of
postage types, including first class, priority mail, express mail and parcel
post;

   Simple and Secure. Our Internet postage solution can be installed in minutes
and includes easy-to-use instructions and an intuitive user interface. Further,
our solution is designed to provide SOHOs the highest level of security and
data integrity as their databases of addresses are stored locally, rather than
uploaded to a remote server. In addition, we enable the accurate tracking and
reporting of postage purchases and usage, thereby limiting employee misuse; and

   Cost-Effective. Our Internet postage solution is cost-effective for SOHO
users relative to traditional postage stamps, by eliminating overposting and
foregone wages from time spent travelling to and from the post office, and
relative to postage meters, by eliminating lease fees. In addition, our
solution enables SOHOs to leverage their existing investments in personal
computers, printers and software.

 Benefits to the U.S. Postal Service

   A New Low-Cost Distribution Channel. Our Internet postage solution enables
the U.S. Postal Service to distribute postage to users through the Internet,
thereby enabling significant manufacturing and distribution cost savings;

   Automation and Operating Efficiencies. Our Internet postage solution enables
the U.S. Postal Service to further automate the handling and processing of
mail, through address verification and correction and extended zip code
printing capabilities;

   Extended Level of Security. Our Internet postage solution provides the
highest level of security and auditing capabilities, which may help the U.S.
Postal Service to reduce the over $150 million dollars annually of postal
fraud; and

   Increased Postal Competitiveness. Our Internet postage solution offers
additional capabilities for sending and tracking packages, such as priority
express or parcel post, enabling the U.S. Postal Service to more effectively
compete against the private parcel shipping industry, such as Federal Express
and United Parcel Service.

Growth Strategy

   Our objective is to be the leading provider of Internet postage solutions.
Key elements of our growth strategy include the following:

 Partner with Industry Leaders to Quickly Acquire Customers

   Our strategy includes partnering with industry leaders to rapidly acquire
customers, build brand recognition and accelerate the adoption of our Internet
postage solution. We have entered into strategic relationships with Microsoft,
Yahoo!, Excite@Home, America Online, Compaq, EarthLink, Francotyp-Postalia,
Dymo-CoStar, Tension Envelope, Avery Dennison and Sunbeam's Pelouze division.
Partnering with well-known and trusted names in the Internet, computer hardware
and software, and business supply industries enables us to leverage our
partners' installed customer bases, distribution channels and marketing
expertise, and facilitate the adoption, usage and accessibility of our Internet
postage solution. We anticipate continuing to add additional strategic partners
as our business grows and we expand our portfolio of products and services.

 Initially Focus on the Large and Growing SOHO Market

   We are initially focusing on the small business, small office and home
office market, collectively known as the SOHO market, due to its attractive
characteristics, which include:

  . a large and growing number of SOHOs;

  . high personal computer penetration;

  . predominant Internet usage via dial up modems over shared data lines; and

  . heavy reliance on postage, yet underserved by traditional solutions.

   We have conducted extensive qualitative and quantitative research on SOHO
users, and have tailored our Internet postage solution to meet their needs.

 Build and Promote Our Brand

   We intend to aggressively build our customer base by increasing awareness of
the E-Stamp brand. We believe that associating our brand with premier strategic
partners and high quality solutions is important to the expansion of our
customer base. As we grow in size, we intend to invest in building brand
awareness through a variety of marketing and promotional techniques, both
independently and in conjunction with our strategic partners. We intend to
promote our brand through television, print and radio advertising, and online
banner advertising through partnerships with high traffic Web sites. We also
plan to generate brand recognition through viral marketing, which involves the
prominent display of our logo and Web site address on our Internet postage.

                                       30

 Leverage Our Technology Platform and Expertise to Extend Our Family of
 Internet Postage Solutions

   We intend to leverage our customer-centric focus, scalable electronic
commerce platform and our patent portfolio to develop a family of Internet
postage solutions for the high volume mailer and corporate enterprise and for
the low volume individual consumer. We intend to offer an intranet-based
solution to the corporate market, through the integration of our technology
into enterprise applications and high speed mail processes, thus enabling
corporate users to print conveniently and efficiently large amounts of Internet
postage for bulk mailings and other corporate purposes. We also intend to
target the consumer market with a server-based solution, that will enable a
user to purchase and store Internet postage directly on our secure electronic
commerce server and print from their local printer. We plan to continue to
develop other solutions that enable users to take advantage of their existing
investments in computing infrastructure and the Internet, and will continue to
invest in and focus our technology development efforts on increasing online
transaction efficiency, reliability and security.

 Pursue Multiple and Recurring Revenue Streams

   We intend to leverage our brand, electronic commerce capabilities and
infrastructure to develop incremental revenue opportunities from a broader
customer base, including the corporate enterprise and the individual consumer.
These opportunities include the following:

   Sale of Postage Related Consumables and Peripherals. Through our Web site,
we intend to offer mailing-related consumables, such as labels and envelopes,
and peripherals, such as mechanical scales, personal computer-enabled digital
scales and label printers. We have created a patented window envelope, and have
partnered with third party vendors of integrated scales and other postage
supplies.

   International Internet Postage Market. We believe that there are significant
opportunities in international markets for our Internet postage solution. In
particular, we believe our Internet postage solution is ideally suited for many
international markets because users pay for connecting to the Internet based on
usage time and thus are seeking solutions that can reduce expensive connection
time.

   Authenticated Document Market. We intend to capitalize on our expertise in
secure payment processing and the printing of authenticated documents to offer
other products and services that can be purchased online and printed from the
desktop, such as tickets and gift certificates.

Our Internet Postage Solution

   Our Internet postage solution enables users to purchase postage over the
Internet, download the postage quickly and efficiently into a secure, silver-
dollar size postage device, and to print the postage at any time from the
desktop directly onto envelopes, labels or documents using standard laser or
inkjet printers. We target today's small business, small office and home office
users, collectively known as SOHOs, most of whom usually connect to the
Internet on modems at speeds of 28.8 or 33.6 kilobytes per second. Our solution
enables users to store postage on their desktop, thereby allowing them to print
postage at their convenience rather than requiring a reconnection to the
Internet each and every time they want to print postage.

   We received U.S. Postal Service approval to begin to sell our Internet
postage solution nationally in August 1999. Our Internet postage solution is
currently available through our Web site and through a toll-free telephone
number, with software and our secure postage device each being delivered via
overnight delivery services, and we expect our Internet postage solution to
also be available at many retail outlets beginning in fall 1999. The estimate
of when our Internet postage solution will be available in retail outlets is a
forward-looking statement that is subject to risks and uncertainties. The
actual timing may differ materially from this estimate as a result of a number
of factors, including the availability of shelf space and product fulfillment.

                                       31

 Installation

   The installation process is simple and can be
completed in a matter of minutes through the use
of a CD-ROM. The E-Stamp Internet postage package
includes all the components needed to use our
Internet postage solution and to connect to
www.e-stamp.com for the purchase of more postage,
receipt of software updates, or to access postal
information. In addition to our easy to install
software, our Internet postage solution also
includes our silver-dollar size, secure postage
device that easily connects onto the back of a
personal computer as shown on the right. The
secure postage device stores the postage and
connects between the parallel port and any other
printer device attached there.
       [Illustration of installation of postage device between printer cable and
                                             parallel port of personal computer]

 Printing Postage

   The following simple three steps are involved in using our Internet postage
solution.

   Step 1: Buy It. The user can purchase Internet postage without ever leaving
the home or office, 24 hours a day, seven days a week. The user simply connects
to our electronic commerce server using a standard Internet connection and then
chooses the amount of Internet postage, up to the $500 maximum storage value
allowed by the U.S. Postal Service, depending on their particular needs and
usage patterns. The Internet postage is then downloaded and stored onto the
Internet postage device.

   Step 2: Print It. After choosing the medium on which to print the Internet
postage, whether directly onto a letter or using an envelope or label, the user
selects the destination address. The addresses are either read directly from
the user's current address database or can be entered with our software. In
either case, the addresses are verified with the Address Matching System from
the U.S. Postal Service contained on CD-ROM at the user's desktop, and the
amount of postage related to the item being sent is calculated. The user then
selects the printer device and prints the Internet postage.

   Step 3: Mail It. The user then drops the professionally posted letters and
packages in the mail or schedules a priority mail pickup from the U.S. Postal
Service.

 Additional Features

   In addition to providing the means to purchase, download and print Internet
postage, we have created other features that enhance the usability of our
Internet postage solution.

   Business Application Integration. We have tightly integrated our solution
with the following leading software applications:

  . Microsoft Word -- Our Internet postage solution integrates tightly with
    Microsoft Word, with our E-Stamp icon appearing in the Microsoft Word
    tool bar, so users can print postage without leaving the application;

  . Microsoft Outlook -- Our software allows users to access addresses in
    Outlook without leaving the E-Stamp application; and

  . Intuit QuickBooks -- Our software's integration with QuickBooks enables
    users to send invoices faster and more easily to their customers.

   Address Software Functionality. Our Internet postage solution enables users
to print Internet postage using their existing mailing databases, and is
compatible with over 17 types of address storage software. Further, addresses
are stored on the user's personal computer with our Internet postage solution,
negating any need to upload confidential information to a shared server.

                                       32
<PAGE>

   Variety of Printing and Mailing Options. Users can choose from 16 different
types of envelopes, labels, air bills and postcards, as well as simply printing
postage directly onto letters and using our patented windowed envelopes.
Customers can use our Internet postage for a number of U.S. Postal Service
mailing options, including first class, priority mail and express mail for
guaranteed overnight delivery.

   Tracking and Reporting. Our Internet postage software includes a function
that allows users to track postage usage, including recipient address, time and
amount.

   Integrated Scale. We have teamed with Sunbeam's Pelouze division to offer an
integrated scale that automatically weighs the letter or package being sent to
correctly calculate the postage required, thus reducing over-posting.

   Internet Postage Supplies. We also provide postage supplies, such as labels
and envelopes, which we have designed to be compatible with our Internet
postage solution. The sale of these postage supplies requires U.S. Postal
Service approval and we are in the process of obtaining necessary approvals.

Strategic Relationships

   We believe that market penetration, brand awareness and adoption of our
Internet postage solution in the early stages is critical to our success. Thus,
we continually focus on enhancing the breadth and depth of market penetration
and offering our customers the most convenient and easy-to-use access to our
Internet postage solution. To achieve these goals, we have established a
strategy of partnering with the industry leaders in business segments related
to the Internet, computer hardware and software, postage and business supplies.
Our strategic relationships allow us to leverage our partners' installed
customer bases, distribution channels and marketing expertise to facilitate the
adoption, usage and accessibility of our Internet postage solution.

   Microsoft. In July 1999, Microsoft, an investor in E-Stamp since 1997,
selected us as its premium online postage partner for its Microsoft Office
Update Web site. As a featured service on the Microsoft Office Update Web site,
we significantly increase our reach into the small business, small office and
home office market by making our Internet postage solution available to the
large base of Microsoft Office users who frequent the site. The initial term of
our agreement with Microsoft is one year, although the agreement is terminable
on 60 days prior notice. We have also worked with Microsoft's product
development teams to integrate our Internet postage solution with Microsoft
applications, including Microsoft Word and Microsoft Outlook.

   Yahoo!. In May 1999, we entered into an advertising and promotion agreement
with Yahoo!. Yahoo! is the leading Internet guide in terms of traffic,
household and business user reach, with over 80 million users worldwide, and is
one of the most recognized brands associated with the Internet. Under this
agreement, we are Yahoo!'s premier Internet postage provider, and Yahoo! users
will have direct access to the E-Stamp service from within the Yahoo! Postal
Center. Additionally, Yahoo! users will have access to our Internet postage
service from other small-business targeted properties throughout the Yahoo!
network through banner advertisements placed by us on these sites.

   Excite@Home. In August 1999, we entered into a binding letter of intent with
Excite@Home to be the preferred Internet postage provider across Excite@Home's
@Work division. This relationship is designed to provide early broadband
adapters with access to our solution through the @Work site. As part of this
relationship, our service offering will be integrated into @Work's portfolio of
products and services. This service is currently expected to be available later
in 1999. Excite@Home also is one of our equity investors.

   America Online. In November 1998, we agreed to become a tenant in America
Online's new Postage Services Center, currently scheduled to launch in August
1999. America Online's Postage Services Center will feature direct links to our
Web site where America Online members can purchase our Internet postage
solution. As part of the agreement, America Online has agreed to promote our
solution until May 2000 with banner advertisements across several of America
Online's branded properties, including CompuServe, AOL.com and Digital City.

                                       33

   Compaq. In June 1998, we entered into an agreement with Compaq to help
accelerate the adoption of Internet postage. Under this agreement, Compaq will
market our Internet postage solution as part of the online services available
to owners of their Prosignia line of personal computers, targeted at the small
business market
and sold through their broad sales channels, and will offer our Internet
postage solution through Compaq's Web site in exchange for which we have agreed
to pay Compaq royalties. The Compaq agreement has an initial term that expires
in June 2001. Compaq also is one of our equity investors.

   Francotyp-Postalia. In August 1999, we entered into a marketing and
distribution agreement with Francotyp-Postalia, Inc., the U.S. division of
Francotyp-Postalia AG & Co., an international market leader in modern office
equipment and services for mail processing. Under this agreement, Francotyp-
Postalia has agreed to offer our Internet postage solution through its Web
site. Additionally, we intend to leverage Francotyp-Postalia's established
distribution channels and existing customer base to distribute our solution.
Francotyp-Postalia also is one of our equity investors.

   Avery Dennison. In July 1999, we entered into a strategic relationship with
Avery Dennison that includes sales, marketing and distribution agreements.
Under this agreement, our Internet postage solution is to be the only online
postage solution promoted in packages of Avery labels and other printable
supplies. Additionally, we have agreed to offer a free sample pack of Avery PC
Postage Labels to our new customers. We plan to sell these labels in our online
supplies store.

   Sunbeam Corp.'s Pelouze Scale Co. Division. In February 1999, we entered
into a strategic marketing and sales agreement with Signature Brands, Inc., a
subsidiary of Sunbeam Corporation, the leading manufacturer and distributor of
postal scales. We intend to leverage Sunbeam's already established distribution
channels and promote our solution with a special Pelouze Internet Postage Scale
for sale in retail, mail order and contract stationery channels. Additionally,
the scale, which is designed to work exclusively with our Internet postage
solution, is currently expected to be available to our customers through our
online store later in 1999.

   Tension Envelope Corporation. In March 1999, Tension Envelope agreed to
become our exclusive supplier for our patented window envelopes. These patented
window envelopes, which we plan to sell through our online supplies store,
feature a special "window" for Internet postage and will save our customers
time by eliminating several steps from the mail preparation process. This
envelope has been submitted for required approvals to the U.S. Postal Service.

   EarthLink. In June 1999, we entered into an agreement with EarthLink, a
leading Internet service provider. Under this agreement, we and EarthLink have
agreed to develop a co-branded postal center accessible to EarthLink's more
than 1.3 million users from their personal start pages and elsewhere in the
EarthLink network. Additionally, EarthLink has agreed to make our Internet
postage solution available for purchase through EarthLink's mall and to place
banner advertisements for our solution in their service. In addition, EarthLink
has agreed to place an advertisement for our solution in each issue of its user
magazine. The initial term of our agreement with EarthLink expires in August
2000.

   Dymo-CoStar. In July 1999, we entered into a strategic marketing and
distribution agreement with Dymo-CoStar, a leading manufacturer of specialty
label printers, related software and supplies. Our agreement with Dymo-CoStar
provides for bundling of a promotional demonstration of our software with many
Dymo-CoStar printers. Additionally, Dymo-CoStar has agreed to jointly promote
our solution in retail channels, promote us to its existing customer base, and
to integrate support for our service directly into its printer software. Dymo-
CoStar's specialty label printer has been approved for sale by the U.S. Postal
Service and the related labels have been submitted for required approvals to
the U.S. Postal Service.

Acquisition of Customers

   The initial focus of our Internet postage solution is on the large and
growing SOHO market, which consists of small businesses, small offices and home
offices. We have established relationships with leading

                                       34
<PAGE>

Internet, computer and business supply companies to distribute our Internet
postage solution through channels most frequented by SOHOs. In addition, we are
leveraging our strategic partners' established customer bases, marketing
efforts and distribution channels to build brand recognition, accelerate
adoption and increase product accessibility. Our plan is to also promote and
extend our brand by conducting ongoing public relations campaigns and
developing affiliation and affinity programs.

   Product Distribution. We intend to make our Internet postage solution
available through all standard distribution channels in order to increase
product availability and accelerate the adoption of Internet postage.
Specifically, we will target the following:

  .  Retail -- We have identified top retail accounts to target for our
     Internet postage solution since SOHOs typically purchase a substantial
     portion of their office supply needs from these sources. These targets,
     such as Best Buy, CompUSA, CDW and Staples, have been selected based on
     the demographics of their customer base, their experience selling
     computer products to small business customers, and their experience
     selling office supplies and mailing-related products; and

  .  Direct Marketing and Mail Order -- We will also offer our products
     directly from our online store at www.e-stamp.com and through our toll-
     free telephone number, as well as through major Internet and mail order
     software resellers, both online and catalog-based.

   Promotional Bundling Arrangements. We have partnered with Compaq, Avery
Dennison, Dymo-CoStar and Sunbeam's Pelouze division to bundle promotions for
our Internet postage solution in selected products, which enables us to
leverage our partners' installed customer base, distribution channels and
marketing experience.

   Affiliate and Affinity Programs. We intend to establish an extensive
affiliate program with premier sites and we will offer other revenue-sharing
opportunities for affiliates who promote or provide links to our products from
their Web site. In addition, we plan to extend promotional offers to trade
associations with substantial SOHO membership.

   Online and Offline Advertising. We currently have strategic relationships in
place with some of the top Internet sites, including Yahoo!, Microsoft, America
Online, Excite@Home and EarthLink, and we intend to partner with additional
high traffic sites in the future. We will also target specific customer
segments through the use of varied online banner advertisements. Further, we
intend to utilize various offline forms of advertising, such as television,
print, radio and other targeted publications that focus on specific attractive
markets for our solution.

   Viral Marketing Programs. The U.S. Postal Service has granted us permission
to include our Web site address and our logo on each Internet postage that is
printed. We have developed our Internet postage to prominently display our logo
and Web site address, in order to further develop our brand recognition and
accelerate the acquisition of new customers through referrals.

U.S. Postal Service Information Based Indicia Program Certification Process

   The U.S. Postal Service recently approved our Internet postage solution
under its Information Based Indicia Program. The Information Based Indicia
Program is a U.S. Postal Service initiative committed to creating new,
convenient, electronic access to postage for mailing customers. Through the
Information Based Indicia Program, the U.S. Postal Service delivers a higher
level of convenience and security to customers with established performance and
evaluation criteria for personal computer postage products.

   For vendors of Internet postage, approval under the Information Based
Indicia Program includes a standardized, ten-stage certification process prior
to commercial release. Information Based Indicia Program participants must
receive U.S. Postal Service authorization at each stage of the certification
process to proceed to the next stage. The second to last stage is a three phase
beta test, which includes customers sending mail

                                       35
<PAGE>

through the mail system. The final stage before commercial release is vendor
product approval, which represents formal approval to begin selling Internet
postage nationally. The significant steps in the certification process and the
time commitment required of a potential Information Based Indicia Program
vendor creates a significant barrier to entry for competitors in the U.S.
Internet postage market.

   The Information Based Indicia Program certification process includes the
following stages:

<TABLE>
     <S>                              <C>
                                       6. U.S. Postal Service address matching
     1. Letter of intent                  system
     2. Non-disclosure agreement       7. Product submission/testing
     3. Operational concept            8. Product infrastructure tests
     4. Software documentation         9. Beta test approval (three phases)
     5. Provider infrastructure plan  10. Vendor product approval (national
                                          distribution)
</TABLE>

   Upon receipt of U.S. Postal Service certification, Information Based Indicia
Program vendors begin national distribution in accordance with approved
quantities and distribution channels. Each approved vendor's commercial roll-
out is initially limited to 10,000 customers, with expanding numbers of
customers based upon successful evaluations by the U.S. Postal Service.

Competition

   We believe that our Internet postage solution is well positioned to compete
in the SOHO market, which consists of small businesses, small offices and home
offices, because of our tight integration with software applications and our
advantages in bandwidth-constrained environments. We will also compete with
providers of traditional postage products such as stamps sold by the U.S.
Postal Service, and services such as Federal Express and United Parcel Service.
In addition to providers of traditional postage products and services, we
compete with three other Information Based Indicia Program vendors, Neopost,
Pitney Bowes and Stamps.com, who have all initiated the certification process
with the U.S. Postal Service. Only one of these, Stamps.com, has been approved
for commercial release by the U.S. Postal Service to date. While the market for
Internet postage is new, we expect that competition will further increase once
Internet postage products become widely available and generally accepted.

   While we believe our Internet postage solution provides significant benefits
over traditional postage methods, especially for the SOHO market, we expect to
continue to also compete with traditional postage methods such as stamps and
metered mail. Postage meters are typically paid for on a monthly lease, require
significant investments in additional supplies such as ink cartridges, charge a
premium for postage and are subject to tampering and theft. There can be no
assurance that customers will change their current postage purchasing habits
and switch to Internet postage products. The failure of a commercially viable
number of users to switch to Internet postage would significantly harm our
business, financial condition and results of operations.

   We may not be able to maintain a competitive position against current or
future competitors as they enter the market in which we compete. This is
particularly true with respect to competitors with greater financial,
marketing, service, support, technical, intellectual property and other
resources than us. Our failure to maintain a competitive position within our
market could seriously harm our business, financial condition and results of
operations. We believe that the principal competitive factors in our market
include: (1) U.S. Postal Service product certification; (2) brand recognition;
(3) integration with other software applications; (4) convenience; (5) service
availability and reliability; (6) price; (7) security; and (8) marketing and
distribution relationships.

Technology

   We have leveraged our technologies, including our desktop software, postage
application programming interface, Internet postage device, patented window
envelope, and systems infrastructure, in order to create a comprehensive
solution that meets our customers' needs and fulfills the U.S. Postal Service's
certification requirements.

                                       36
<PAGE>

   Desktop Software. Our desktop software enables users to print Internet
postage offline without maintaining a persistent Internet connection. The
software is designed to interface with our proprietary postage device to print
the recipient's address and Internet postage in one step onto envelopes,
labels, and documents. The recipient's address can be selected using the built-
in support for many popular applications, including Microsoft Word, Microsoft
Outlook and Intuit's QuickBooks, without the user having to upload data over
the Internet or separately type the address. This is a significant advantage
over other Internet postage products which require the user to type in or
import addresses from other software packages and force them to keep multiple
copies of the same address synchronized across multiple address books. In
addition, the software has a built-in electronic software update feature which
automatically updates postage rates and the software itself ensuring that each
customer always has the most current version of our software. The software
includes a postage application programming interface which enables other
software vendors to integrate their software with ours.

   Postage Application Programming Interface. We built our software from the
ground up so that it can be integrated as a component of another software
application. This means we can virtually any software application can be
"postage-enabled" to print Internet postage onto envelopes, labels, or
documents. Through this technology, we believe that we can create the tight
integration with popular business applications.

   Internet Postage Device. We have developed a proprietary silver-dollar size
Internet postage device that securely stores the postage value our customers
buy. The postage device connects to a personal computer's parallel port,
between the personal computer and the printer. The postage device enables our
users to print postage without the need for being connected to the Internet,
because account balances are stored on the device, not on a remote server. The
postage device is also secure and tamper-resistant, disabling itself if anyone
attempts to open or tamper with it. Our Internet postage device has been tested
by the National Institute of Standards and Technology and certified as Federal
Information Processing Standard 140-1 compliant at security levels 3 and
partially 4. Overall security was reviewed by a Cryptographic Equipment
Assessment Laboratory and Internet Security was reviewed by ISS Group, a
leading Internet security company.

   Patented Window Envelope. We have developed and patented a special window
envelope that has an additional window in the upper right corner for postage.
This enables postage to be printed directly on documents, folded in thirds and
inserted into one of our envelopes. They are a significant time-saver because
they eliminate the need to separately prepare an envelope or label. Tension
Envelope will be manufacturing this envelope for us and we plan to offer it to
our customers on our Web site.

   Systems Infrastructure. Our systems have been designed to be scalable as our
business grows and to allow for rapid deployment of our Internet postage
solution. As the quantity of purchases or number of users accessing our systems
increases, we have developed our systems to incrementally grow through the
necessary additions. Our systems are based on the Microsoft Windows NT,
Transaction Server and SQL Server environment. For our Web site, we utilize
Javascript and Active Server Pages.

Future Product Development

   We are currently developing a server-based solution that is targeted at
broadband-enabled users. As estimated by Forrester Research, broadband access
was only utilized by 2% of online users in 1998, but will increase to 26% in
2002. Once broadband connections become more prevalent and customers have
dedicated Internet access, our server-based solution will be positioned to meet
the needs of this base of users. The server-based solution will enable a user
to purchase and store Internet postage directly on our secure electronic
commerce server and print from their local printer.

Employees

   As of June 30, 1999, we employed 75 full-time people, including 29 in
engineering, 13 in operations, eight in customer service and support, 13 in
sales, marketing and business development, and 12 in general and

                                       37
<PAGE>

administrative functions. Based on our growth plans, we anticipate hiring a
significant number of employees over the next 12 months. From time to time, we
employ independent contractors to support our research and development,
marketing, sales and support and administrative organizations. Our employees
are not represented by any collective bargaining unit, and we have never
experienced a work stoppage. We believe our relations with our employees are
good.

Intellectual Property

   We regard our technology as proprietary and attempt to protect it by relying
on patent, trademark, service mark, copyright and trade secret laws and
restrictions on disclosure and transferring title and other methods. We have
been issued over 20 U.S. patents and have 12 patent applications pending. We
consider patents to be a significant part of our intellectual property, and
will remain so for the foreseeable future. We also generally enter into
confidentiality or license agreements with our employees and consultants, and
generally control access to and distribution of our documentation and other
proprietary information. Despite these precautions, it may be possible for a
third party to copy or otherwise obtain and use our proprietary information
without authorization or to develop similar technology independently. We are in
the process of pursuing the registration in the U.S. for a number of our
trademarks and service marks, including "E-Stamp." Effective trademark, service
mark, copyright and trade secret protection may not be available in every
country in which our solutions are distributed or made available over the
Internet, and policing unauthorized use of our proprietary information is
difficult.

   Despite efforts to protect our intellectual property rights, we face
substantial uncertainty regarding the impact that other parties' intellectual
property positions will have on the Internet postage market. In particular,
Pitney Bowes has sent formal comments to the U.S. Postal Service asserting that
intellectual property of Pitney Bowes would be infringed by products meeting
the requirements of the Information Based Indicia Program's specifications.
Furthermore, in June 1999, Pitney Bowes filed a lawsuit in the U.S. District
Court against us alleging infringement of Pitney Bowes patents. For a
discussion of claims by Pitney Bowes and risks associated with intellectual
property, please refer to "Risk Factors--Intellectual property infringement
claims, including claims by Pitney Bowes against us, could prevent or delay our
ability to provide our Internet postage solutions" and "--Legal Proceedings."

Facilities

   Our headquarters are currently located in a leased facility in San Mateo,
California, consisting of approximately 25,000 square feet of office space. The
office space is under a 15-month lease which will expire in June 2000. We will
need to obtain additional office space prior to the end of 1999 and are
currently in discussions with respect to additional space.

Legal Proceedings

   On June 10, 1999, Pitney Bowes filed suit against us in the U.S. District
Court for the District of Delaware alleging infringement of Pitney Bowes
patents. The suit alleges that we are infringing seven patents held by Pitney
Bowes related to postage application systems and seeks treble damages, a
preliminary and permanent injunction from further alleged infringement,
attorneys' fees and other unspecified damages. One week later, Pitney Bowes
filed a similar complaint against one of our competitors, Stamps.com, alleging
infringement of two of the seven Pitney Bowes patents alleged in the E-Stamp
complaint. On July 30, 1999, we filed our answer to Pitney Bowes' complaint in
which we deny all allegations of patent infringement and assert certain
affirmative and other defenses based on statutory and common law grounds,
including inequitable conduct on the part of Pitney Bowes in its procurement of
patents in proceedings before the U.S. Patent and Trademark Office. As part of
the answer, we also brought various counterclaims against Pitney Bowes claiming
Pitney Bowes' violation of Section 2 of the Sherman Act and intentional and
tortious interference with E-Stamp's business relations based, in part, upon
our allegations that Pitney Bowes has unlawfully maintained its

                                       38
<PAGE>

monopoly power in the postage metering market through a scheme to defraud the
U.S. Patent and Trademark Office and its efforts to discourage potential
investors and strategic partners from investing and entering into partnerships
with E-Stamp. Our suit seeks compensatory and treble damages, injunctive relief
and recovery of attorney's fees. We are continuing to investigate the claims
against us as well as infringement by Pitney Bowes of our patents, and may
assert additional defenses or pursue additional counterclaims or independent
claims against Pitney Bowes in the future.

   Pendency of the litigation can be expected to result in significant expenses
to us and the diversion of management time and other resources. If Pitney Bowes
is successful in its claims against us, then we may be hindered or even
prevented from competing in the Internet postage market and our operations
would be severely harmed. For example, the Pitney Bowes suit could result in
limitations on how we implement our solutions, delays and costs associated with
redesigning our solutions and payments of license fees and other payments. An
injunction obtained by Pitney Bowes could eliminate our ability to market
critical products or services. See "Risk Factors--Intellectual property
infringement claims, including claims by Pitney Bowes against us, could prevent
or hinder our ability to sell Internet postage."

   On May 10, 1999, in U.S. District Court, E-Stamp obtained a temporary
restraining order against Dave Lahoti ordering Mr. Lahoti (a cybersquatter) to
refrain from using his Web site, which he had registered as "estamps.com." On
June 14, 1999, the U.S. District Court granted a preliminary injunction
requiring Mr. Lahoti to refrain from using his Web site in connection with
Internet postage and to place a disclaimer identifying that his Web site is not
associated with E-Stamp Corporation. We are seeking damages and a permanent
injunction in connection with this matter.

Classified Board

   Our certificate of incorporation provides for a classified board of
directors consisting of three classes of directors, each serving staggered
three-year terms. As a result, a portion of our board of directors will be
elected each year. Robert H. Ewald and Thomas L. Rosch have been designated
Class I directors whose terms expire at the 2000 annual meeting of
stockholders. Marcelo A. Gumucio and Adam Wagner have been designated Class II
directors whose terms expire at the 2001 annual meeting of stockholders.
Gregory S. Stanger and John V. Balen have been designated as Class III
directors whose terms expire at the 2002 annual meeting of stockholders. This
classification of the board of directors may delay or prevent a change in
control of our company or in our management. See "Description of Capital
Stock--Antitakeover Effects of Provisions of Certain Charter Provisions, Bylaws
and Delaware Law."

   Executive officers are appointed by the board of directors on an annual
basis and serve until their successors have been duly elected and qualified.
There are no family relationships among any of our directors, officers or key
employees.

Board Committees

   We established an audit committee and a compensation committee in July 1998.

   Our audit committee currently consists of Messrs. Balen and Wagner. The
audit committee reviews our internal accounting procedures and consults with
and reviews the services provided our independent accountants.

   Our compensation committee currently consists of Messrs. Balen, Rosch and

directors the compensation and benefits of our employees.

Compensation Committee Interlocks and Insider Participation

   Prior to establishing the compensation committee, the board of directors as
a whole performed the functions delegated to the compensation committee. No
member of the board of directors or the compensation committee serves as a
member of the board of directors or compensation committee of any entity that
has one or more executive officers serving as a member of our board of
directors or compensation committee.

                       Option Grants in Last Fiscal Year

   The following table sets forth certain information with respect to stock
options granted to each of the Named Executive Officers in the fiscal year
ended December 31, 1998, including the potential realizable value over the ten-
year term of the options, based on assumed rates of stock appreciation of 5%
and 10%, compounded annually. These assumed rates of appreciation comply with
the rules of the Securities and Exchange Commission and do not represent our
estimate of future stock price. Actual gains, if any, on stock option exercises
will be dependent on the future performance of our common stock.

   In the fiscal year ended December 31, 1998, we granted options to purchase
up to an aggregate of 1,361,055 shares to employees, directors and consultants.
All options were granted under our 1996 Stock Option and Restricted Stock Plan
at exercise prices at or above the fair market value of our common stock on the
date of grant, as determined in good faith by the board of directors. All
options have a term of ten years. Optionees may pay the exercise price by cash,
certified check, or delivery of already-owned shares of our common stock. All
options to the Named Executive Officers are immediately exercisable upon grant;
however, any unvested shares may be repurchased by us at their cost in the
event of the optionee's termination of employment. All option shares vest over
four years, with 25% of the option shares vesting one year after the option
grant date, and the remaining option shares vesting ratably each quarter
thereafter.

   The following table describes for the Named Executive Officers their option
exercises for the fiscal year ended December 31, 1998, and exercisable and
unexercisable options held by them as of December 31, 1998.

   The "Value of Unexercised In-the-Money Options at December 31, 1998" is
based on a value of $0.80 per share, the fair market value of our common stock
as of December 31, 1998, as determined by the board of directors, less the per
share exercise price, multiplied by the number of shares issued upon exercise
of the option. All options were granted under our 1996 Stock Option and
Restricted Stock Plan. The shares vest over four years, with 25% of the shares
vesting one year after the grant date and the remaining shares vesting ratably
each quarter thereafter.

1999 Stock Plan

   The board of directors adopted our 1999 Stock Plan, referred to as the 1999
Plan, in August 1999, subject to approval of our stockholders. This stock
option plan provides for the grant to employees of incentive stock options
within the meaning of Section 422 of the Internal Revenue Code of 1986, as
amended, and for the grant to employees, directors and consultants of
nonstatutory stock options and stock purchase rights.

   A total of 2,000,000 shares of common stock is reserved for issuance, plus
annual increases, beginning in fiscal year 2000, equal to the lesser of:

  . 1,000,000 shares;

  . 3% of the outstanding shares on such date; or

  . a lesser amount determined by the board.

   The stock plan administrator, which is the board of directors or a committee
of the board, administers the 1999 Plan. In the case of options intended to
qualify as "performance based compensation" within the meaning of the Internal
Revenue Code of 1986, as amended, the committee will consist of two or more
"outside directors" within the meaning of the Internal Revenue Code of 1986, as
amended.

   The administrator determines the exercise price of nonstatutory stock
options granted under the 1999 Plan, but with respect to nonstatutory stock
options intended to qualify as "performance based compensation" within the
meaning of the Internal Revenue Code of 1986, as amended, the exercise price
must be at least equal to the fair market value of the common stock on the date
of grant. The exercise price of incentive stock options granted under the 1999
Plan must be at least equal to the fair market value of the common stock on the
date of grant. For any participant who owns stock possessing more than 10% of
the voting power of all classes of our capital stock, the exercise price of any
incentive stock option must equal at least 110% of the fair value on the date
of grant and the term of such incentive stock option must not exceed five
years. The term of all other options granted under the stock option plan may
not exceed 10 years.

   An optionee must exercise an option granted under the 1999 Plan generally
within three months after the end of the optionee's status as an employee,
director or consultant of E-Stamp, or within 12 months after the optionee's
termination by death or disability, but in no event later than the expiration
of the option's term. Unless determined otherwise by the administrator, an
optionee generally may not transfer options and stock purchase rights granted
under the 1999 Plan.

   The administrator determines the exercise price of stock purchase rights
granted under the 1999 Plan. In case of stock purchase rights, unless the
administrator determines otherwise, the restricted stock purchase agreement
entered into in connection with the exercise of the stock purchase rights
contains a repurchase option that we may exercise upon the voluntary or
involuntary termination of the purchaser's service with us for any reason,
including death or disability. The purchase price for shares we repurchase
under the restricted stock purchase agreements will be the original price paid
by the purchaser and may be paid by cancellation of any indebtedness of the
purchaser to us. The repurchase option lapses at a rate that the administrator
determines.

   The 1999 Plan provides that in the event of our merger with or into another
corporation or the sale of substantially all of our assets, the successor
corporation will assume or substitute each option or stock purchase right. If
the outstanding options or stock purchase rights are not assumed or
substituted, the administrator will provide notice to the optionee that he or
she has the right to exercise each outstanding option or stock purchase right
as to all of the shares subject to the option or stock purchase right,
including shares that would not otherwise be exercisable, for a period of 30
days from the date of the notice. The options and stock purchase rights will
terminate upon the expiration of the 30-day period.

   Unless terminated sooner, the 1999 Plan will terminate automatically in
2009. In addition, the administrator has the authority to amend, suspend or
terminate the 1999 Plan, provided that no such action may affect any share of
common stock previously issued and sold or any option previously granted.

1996 Stock Option and Restricted Stock Plan

   Our 1996 Stock Option and Restricted Stock Plan, referred to as the 1996
Plan, was adopted by the board of directors and subsequently approved by our
stockholders. The 1996 Plan provides for the grant to employees of incentive
stock options within the meaning of Section 422 of the Internal Revenue Code of
1986, as amended, and for the grant to employees and consultants of
nonstatutory stock options and restricted stock rights.

   The board of directors has determined that no future options or restricted
stock rights will be granted under our 1996 Plan after the effective date of
this offering. However, the board or a committee of our board of directors will
administer the options and stock purchase rights granted under the 1996 Plan
that are outstanding on the effective date of this offering. A total of
4,750,000 shares of common stock were authorized for issuance under the 1996
Plan. As of August 10, 1999, options to purchase an aggregate of 1,172,790
shares of our common stock were outstanding under this stock option plan, and a
total of 3,555,712 shares that have been issued pursuant to the exercise of
options granted under the 1996 Plan were outstanding.

   The options outstanding at the time of this offering will remain subject to
the terms of the agreements evidencing such options and the terms of the 1996
Plan. The 1996 Plan provides that in the event of a merger of the Company with
or into another corporation, or the sale of substantially all of the Company's
assets, each outstanding option will terminate immediately prior to such
transaction, unless determined otherwise by the plan administrator.

1999 Employee Stock Purchase Plan

   Our 1999 Employee Stock Purchase Plan was adopted by our board of directors
in August 1999, subject to approval of our stockholders. A total of 500,000
shares of common stock has been reserved for issuance under the purchase plan,
plus annual increases equal to the lesser of:

  . 350,000 shares;

  . 1% of the outstanding shares on such date; or

  . a lesser amount determined by the board.

   The board of directors or a committee appointed by the board administers the
stock purchase plan. The board or its committee has full and exclusive
authority to interpret the terms of the stock purchase plan and determine
eligibility.

   Employees are eligible to participate if they are employed by us or any
participating subsidiary for at least 20 hours per week and more than five
months in any calendar year. However, the following employees may not be
granted options to purchase stock under the purchase plan:

  . any employee who immediately after grant owns stock possessing 5% or more
    of the total combined voting power or value of all classes of our capital
    stock; or

  . any employee whose rights to purchase stock under all of our employee
    stock purchase plans accrues at a rate which exceeds $25,000 worth of
    stock for each calendar year.

   The stock purchase plan, which is intended to qualify under Section 423 of
the United States tax code, contains consecutive, overlapping 24 month offering
periods. Each offering period includes four six-month purchase periods. The
offering periods generally start on the first trading day on or after May 15
and November 15 of each year, except for the first such offering period which
will commence on the first trading day on or after the effective date of this
offering and will end on the last trading day on or before November 14, 2001.

                                       46
<PAGE>

   Participants may purchase common stock through payroll deductions of up to
15% of the participant's eligible compensation. The maximum number of shares a
participant may purchase during a single offering period is 5,000 shares.

   Amounts deducted and accumulated by the participant are used to purchase
shares of common stock at the end of each offering period. The price of stock
purchased under the purchase plan is 85% of the lower of the fair market value
of the common stock at the beginning of the offering period and the end of each
offering period. In the event the fair market value at the end of a purchase
period is less than the fair market value at the beginning of the offering
period, participants will withdraw from the current offering period following
the exercise and will automatically re-enroll in a new offering period.
Participants may end their participation at any time during an offering period,
and they will be paid their payroll deductions to date. Participation ends
automatically upon termination of employment with E-Stamp.

   The purchase plan provides that, if we merge with or into another
corporation or sell substantially all of our assets, each outstanding option
may be assumed or substituted for by the successor corporation. If the
successor corporation refuses to assume or substitute for the outstanding
options, the offering period then in progress will be shortened and a new
exercise date will be set, which will occur before the proposed sale or merger.

   The purchase plan will become effective on the effective date of this
offering and will terminate in 2009. The board of directors has the authority
to amend or terminate the purchase plan, except that no such action may
adversely affect any outstanding rights to purchase stock.

1999 Director Option Plan

   Non-employee directors are entitled to participate in our 1999 Director
Option Plan. The board of directors adopted the director plan in August 1999,
subject to approval of our stockholders, but it will not become effective until
the day following the closing of this offering. The director plan has a term of
ten years, unless terminated sooner by the board. A total of 300,000 shares of
common stock have been reserved for issuance under the director plan.

   The director plan provides for the automatic grant of 40,000 shares of
common stock to each non-employee director who first becomes a non-employee
director after adoption of this plan, and who does not beneficially hold more
than one percent (1%) of the total voting power of our voting securities on the
date of grant. The shares purchasable under this option shall vest over four
years at the rate of 1/48th per month. In addition, after this offering, each
non-employee director who has served on the board for at least the six previous
months, and who does not beneficially hold more than one percent (1%) of the
total voting power of our voting securities on the date of grant, will be
granted an option to purchase 2,500 shares of common stock on the date of each
annual meeting of our stockholders. The shares purchasable under this option
shall vest over one year at the rate of 1/12th per month. Each option granted
to a non-employee director under this director plan will have a term of ten
years. The exercise price of all options shall be 100% of the fair market value
per share of the common stock, generally determined with reference to the
closing price of the common stock as reported on the Nasdaq National Market on
the date of grant.

   Options granted under the director plan must be exercised within three
months of the end of the optionee's tenure as a director, or within twelve
months after such director's termination by death or disability to the extent
the option was exercisable on the date of termination, but not later than the
expiration of the option's ten year term.

1996 Non-Employee Director Stock Option Plan

   Our 1996 Non-Employee Director Stock Option Plan, referred to as the 1996
Director Plan, was adopted by the Board and approved by the stockholders. Our
board of directors terminated this 1996 Director Plan with

                                       47
<PAGE>

respect to future grants. However, outstanding options granted under this plan
will remain outstanding and subject to the terms and conditions of the
agreements evidencing such options and the terms of the 1996 Director Plan.

   A total of 100,000 shares of our common stock are authorized for issuance
under the 1996 Director Plan. As of August 10, 1999, a total of 15,250 shares
were subject to outstanding options granted under this plan. Although 84,750
shares remain available for further grant of options under the 1996 Director
Plan, no more options will be granted under this plan.

401(k) Plan

   We sponsor a 401(k) plan which provides eligible employees located in the
United States an opportunity to save money for their retirement on a tax
deferred basis. The 401(k) plan is intended to qualify under Sections 401(a)
and 401(k) of the Internal Revenue Code of 1986, as amended. Eligible employees
may elect to reduce their current eligible compensation by up to 15%, subject
to the statutory annual limit in 1999 of $10,000, and to have the amount of
such reduction contributed on their behalf to the 401(k) plan. We currently
provide a matching contribution to those eligible employees who have elected to
participate in the 401(k) plan equal to 50% of the first 4% of their eligible
contributions to the 401(k) plan. In addition, the 401(k) plan permits, but
does not require, an additional discretionary profit sharing contribution to be
made by us on behalf of certain eligible employees. To date, we have not made
any such discretionary profit sharing contribution to the 401(k) plan.
Contributions that are made to the 401(k) plan, whether if made by the eligible
employees, or by us, and the investment earnings thereon, are not taxable to
employees until such amounts are withdrawn from the 401(k) plan. However, any
contributions made by us will be deductible in the taxable year they are made.
The 401(k) plan may be amended or terminated by us at anytime, and in our sole
discretion.

Employment Agreements

   We have issued offer letters to each of Robert H. Ewald, Anthony H. Lewis,
Jr., Roderick Witmond, Edward Malysz and Marcelo A. Gumucio pursuant to which
each is entitled to a base salary, bonuses and an option to purchase shares of
our common stock. In addition, we agreed to give Mr. Ewald a grant of 100,000
shares of common stock if we successfully complete an initial public offering
within twelve months of his commencement of employment. We agreed to provide
Mr. Lewis with a promissory note in the amount of $30,000 which will be
forgiven in the event he is terminated without cause prior to one year of
service or upon completion of one year of service from his start date. We
agreed that if Mr. Gumucio is involuntarily terminated within one year of his
start date, 25% of his option shall become immediately exercisable, and if we
experience a change of control, Mr. Gumucio's option shall become immediately
exercisable.

   We have entered into employment agreements with each of Nicole Eagan, Martin
Pagel and Thomas J. Reinemer pursuant to which each is entitled to a base
salary, bonuses, an option to purchase shares of common stock and an option to
purchase shares of restricted common stock. Under these agreements, if any of
Nicole Eagan, Martin Pagel or Thomas J. Reinemer are terminated without cause,
he or she will be entitled to the payment of six months of his or her base
salary.

Limitations on Directors' Liability and Indemnification

   Our certificate of incorporation limits the liability of directors to the
maximum extent permitted by Delaware law. Delaware law provides that directors
of a corporation will not be personally liable for monetary damages for breach
of their fiduciary duties as directors, except liability for any of the
following:

  . any breach of their duty of loyalty to the corporation or its
    stockholders;

  . acts or omissions not in good faith or which involve intentional
    misconduct or a knowing violation of law;

  . unlawful payments of dividends or unlawful stock repurchases or
    redemptions; or

  . any transaction from which the director derived an improper personal
    benefit.

                                       48
<PAGE>

   This limitation of liability does not apply to liabilities arising under the
federal securities laws and does not affect the availability of equitable
remedies such as injunctive relief or rescission.

   Our certificate of incorporation and bylaws provide that we shall indemnify
our directors and executive officers and may indemnify our other officers and
employees and other agents to the fullest extent permitted by law. We believe
that indemnification under our bylaws covers at least negligence and gross
negligence on the part of indemnified parties. Our bylaws also permit us to
secure insurance on behalf of any officer, director, employee or other agent
for any liability arising out of his or her actions in such capacity,
regardless of whether our bylaws would permit indemnification.

   We have entered into agreements to indemnify our directors and executive
officers, in addition to indemnification provided for in our bylaws. These
agreements, among other things, provide for indemnification of our directors
and executive officers for expenses, judgments, fines and settlement amounts
incurred by any such person in any action or proceeding arising out of such
person's services as a director or executive officer or at our request. We
believe that these provisions and agreements are necessary to attract and
retain qualified persons as directors and executive officers.

   The limited liability and indemnification provisions in our certificate of
incorporation and bylaws may discourage stockholders from bringing a lawsuit
against our directors for breach of their fiduciary duty and may reduce the
likelihood of derivative litigation against our directors and officers, even
though a derivative litigation, if successful, might otherwise benefit us and
our stockholders. A stockholder's investment in us may be adversely affected to
the extent we pay the costs of settlement or damage awards against our
directors or officers under these indemnification provisions.

   At present, there is no pending litigation or proceeding involving any of
our directors, officers or employees in which indemnification is sought, nor
are we aware of any threatened litigation that may result in claims for
indemnification.

                              CERTAIN TRANSACTIONS

   During the last two years, there has not been, nor is there currently
proposed, any transaction or series of similar transactions to which we were or
are to be a party in which the amount involved exceeds $60,000 and in which any
director, executive officer or holder of more than 5% of our common stock had
or will have a director or indirect interest other than compensation
arrangements, which are described where required under "Management," and the
transactions described below.

$2.40 per share. In July 1998, we sold 4,188,000 shares of Series B preferred
stock for $3.82 per share. In August 1999, we sold 2,931,229 shares of Series C

Certain Sales to Executive Officers

   On May 30, 1999, we sold 1,225,000 shares of common stock at a price of
$0.90 per share to Robert H. Ewald. We have the right to repurchase such shares
in the event Mr. Ewald's services to us terminate, which right lapses
progressively over four years after the date of grant. Mr. Ewald paid for such
shares with a full-recourse, five-year $1,102,500 promissory note, secured by
the purchased shares. The note bears interest at a rate of 6% per annum.

   On June 12, 1998, we sold an aggregate of 266,154 shares of common stock at
a price of $0.25 per share for 25,625 shares and $0.50 per share for 240,529
shares to Nicole Eagan. We have the right to repurchase such shares in the
event Ms. Eagan's services to us terminate, which right lapses progressively
over four years after the date of grant. Ms. Eagan paid for such shares with a
full-recourse, five-year $126,671 promissory note, secured by the purchased
shares. The note bears interest at a rate of 6% per annum.

   On June 12, 1998, we sold an aggregate of 180,260 shares of common stock at
a price of $0.25 per share for 25,625 shares and $0.50 per share for 154,635
shares to Martin Pagel. We have the right to repurchase such shares in the

                             PRINCIPAL STOCKHOLDERS

   The table on the following page sets forth information regarding the
beneficial ownership of our common stock as of August 10, 1999, by the
following individuals or groups:

  . each person or entity who we know beneficially owns more than 5% of our
    outstanding stock;

  . each of the Named Executive Officers;

  . each of our directors; and

  . all directors and executive officers as a group.

   Unless otherwise indicated, the address for each stockholder listed in the
following table is c/o E-Stamp Corporation, 2855 Campus Drive, Suite 100, San
Mateo, California 94403. Beneficial ownership is determined in accordance with
the rules of the Securities and Exchange Commission. In computing the number of
shares beneficially owned by a person and the percentage ownership of that
person, shares of common stock subject to options or warrants held by that
person that are currently exercisable or will become exercisable within 60 days
after August 10, 1999, are deemed outstanding, while the shares are not deemed
outstanding for purposes of computing percentage ownership of any other person.
Except as otherwise indicated, and subject to applicable community property
laws, the persons named in the table have sole voting and investment power with
respect to all shares of common stock held by them.

   Applicable percentage ownership in the following table is based on
23,541,541 shares of common stock outstanding as of August 10, 1999, as
adjusted to reflect the conversion of all outstanding shares of preferred stock
upon the closing of this offering. The numbers shown in the table below assume
no exercise by the underwriters of their over-allotment option.

                          DESCRIPTION OF CAPITAL STOCK

General

   Upon the completion of this offering, we will be authorized to issue
200,000,000 shares of common stock, $0.001 par value, and 10,000,000 shares of
undesignated preferred stock, $0.001 par value. The following description of
our capital stock does not purport to be complete and is subject to and
qualified in its entirety by our certificate of incorporation and bylaws, which
are included as exhibits to the registration statement of which this prospectus
forms a part, and by the provisions of applicable Delaware law.

Common Stock

   As of August 10, 1999, there were 23,541,541 shares of common stock
outstanding which were held of record by approximately 465 stockholders, as
adjusted for the conversion of all outstanding shares of convertible preferred
stock into common stock, which will occur upon the closing of this offering.

   The holders of common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Subject to preferences that may
be applicable to any outstanding preferred stock, the holders of common stock
are entitled to receive ratably such dividends, if any, as may be declared from
time to time by the board of directors out of funds legally available for that
purpose. See "Dividend Policy." In the event of our liquidation, dissolution or
winding up, the holders of common stock are entitled to share ratably in all
assets remaining after payment of liabilities, subject to prior distribution
rights of preferred stock, if any, then outstanding. The holders of common
stock have no preemptive or conversion rights or other subscription rights.
There are no redemption or sinking fund provisions applicable to the common
stock. All outstanding shares of common stock are fully paid and nonassessable.
The shares of common stock to be issued upon the closing of this offering will
be fully paid and nonassessable.

Preferred Stock

   The board of directors has the authority, without action by the
stockholders, to designate and issue preferred stock in one or more series and
to designate the rights, preferences and privileges of each series, which may
be greater than the rights of the common stock. It is not possible to state the
actual effect of the issuance of any shares of preferred stock upon the rights
of holders of the common stock until the board of directors determines the
specific rights of the holders of such preferred stock. However, the effects
might include, among other things:

  . restricting dividends on the common stock;

  . diluting the voting power of the common stock;

  . impairing the liquidation rights of the common stock; or

  . delaying or preventing a change in control of us without further action
    by the stockholders.

   Upon the closing no shares of preferred stock will be outstanding, and we
have no present plans to issue any shares of preferred stock.

Warrants

   At August 10, 1999, there were warrants outstanding to purchase 21,235
shares of Series C preferred stock, which will be exercisable to purchase as
aggregate of 21,235 shares of common stock upon closing of this offering. At
August 10, 1999, there were warrants outstanding to purchase 38,797 shares of
common stock.

                                       55
<PAGE>

Registration Rights

   The holders of preferred stock convertible into 9,619,229 shares of common
stock (the "registrable securities") are entitled to certain rights with
respect to registration of such shares under the Securities Act. These rights
are provided under the terms of an agreement between the holders of registrable
securities and us. Beginning 180 days following the date of this prospectus,
holders of at least 25% of the then outstanding registrable securities obtained
from conversion of our Series A preferred stock (or such lesser percentage if
the anticipated aggregate offering price would exceed $15,000,000) may require
on one occasion that we register their shares for public resale. Beginning 180
days following the date of this prospectus, holders of at least 25% of the then
outstanding registrable securities obtained from conversion of our Series B
preferred stock (or such lesser percentage if the anticipated aggregate
offering price would exceed $15,000,000) may require on one occasion that we
register their shares for public resale. Beginning 180 days following the date
of this prospectus, holders of at least 25% of the then outstanding registrable
securities obtained from conversion of our Series C preferred stock (or such
lesser percentage of the anticipated aggregate offering price would exceed
$15,000,000) may require on one occasion that we register their shares for
public resale. However, we may defer such registration for 90 days in view of
market conditions. Also, holders of registrable securities may require on two
separate occasions within any twelve month period that we register their shares
for public resale on Form S-3 or similar short-form registration if the value
of the securities to be registered is at least $500,000, however we may defer
such registration for 90 days in view of market conditions. Furthermore, in the
event we elect to register any of our shares of common stock for purposes of
effecting any public offering, the holders of registrable securities are
entitled to include their shares of common stock in the registration, but we
may reduce the number of shares proposed to be registered in view of market
conditions. These registration rights have been waived with respect to this
offering. All expenses in connection with any registration, other than
underwriting discounts and commissions, will be borne by us. All registration
rights will terminate five years following the consummation of this offering,
or, with respect to each holder of registrable securities, at such time as the
holder is entitled to sell all of its shares in any 90 day period under Rule
144 of the Securities Act.

Delaware Anti-Takeover Law and Certain Charter and Bylaw Provisions

   Certain provisions of Delaware law and our certificate of incorporation and
bylaws could make the following more difficult:

  . the acquisition of us by means of a tender offer;

  . acquisition of us by means of a proxy contest or otherwise; or

  . the removal of our incumbent officers and directors.

   These provisions, summarized below, are expected to discourage certain types
of coercive takeover practices and inadequate takeover bids. These provisions
are also designed to encourage persons seeking to acquire control of us to
first negotiate with our board. We believe that the benefits of increased
protection of our potential ability to negotiate with the proponent of an
unfriendly or unsolicited proposal to acquire or restructure us outweigh the
disadvantages of discouraging such proposals because negotiation of such
proposals could result in an improvement of their terms.

   Election and Removal of Directors. Our board of directors is divided into
three classes. The directors in each class will serve for a three-year term,
one class being elected each year by our stockholders. See "Management--Board
of directors and Executive Officers." This system of electing and removing
directors may tend to discourage a third party from making a tender offer or
otherwise attempting to obtain control of us because it generally makes it more
difficult for stockholders to replace a majority of the directors.

   Stockholder Meetings. Under our certificate of incorporation, only the board
of directors, the chairman of the board and the chief executive officer may
call special meetings of stockholders.

                                       56
<PAGE>

   Requirements for Advance Notification of Stockholder Nominations and
Proposals. Our bylaws establish advance notice procedures with respect to
stockholder proposals and the nomination of candidates for election as
directors, other than nominations made by or at the direction of the board of
directors or a committee of the board.

   Delaware AntiTakeover Law. We are subject to Section 203 of the Delaware
General Corporation Law, an anti-takeover law. In general, Section 203
prohibits a publicly held Delaware corporation from engaging in a "business
combination" with an "interested stockholder" for a period of three years
following the date the person became an interested stockholder, unless the
"business combination" or the transaction in which the person became an
interested stockholder is approved in a prescribed manner. Generally, a
"business combination" includes a merger, asset or stock sale, or other
transaction resulting in a financial benefit to the interested stockholder.
Generally, an "interested stockholder" is a person who, together with
affiliates and associates, owns or within three years prior to the
determination of interested stockholder status, did own, 15% or more of a
corporation's voting stock. The existence of this provision may have an anti-
takeover effect with respect to transactions not approved in advance by the
board of directors, including discouraging attempts that might result in a
premium over the market price for the shares of common stock held by
stockholders.

   Elimination of Stockholder Action By Written Consent. Our certificate of
incorporation eliminates the right of stockholders to act by written consent
without a meeting at any time when we have 500 or more record stockholders.

   Elimination of Cumulative Voting. Our certificate of incorporation and
bylaws do not provide for cumulative voting in the election of directors.

   Undesignated Preferred Stock. The authorization of undesignated preferred
stock makes it possible for the board of directors to issue preferred stock
with voting or other rights or preferences that could impede the success of
any attempt to change control of us. These and other provisions may have the
effect of deferring hostile takeovers or delaying changes in control or
management of us.

   Amendment of Charter Provisions. The amendment of any of the above
provisions would require approval by holders of at least 66 2/3% of the
outstanding common stock.

Transfer Agent and Registrar

   The transfer agent and registrar for the common stock is Continental Stock
Transfer and Trust Company.

Nasdaq National Market Listing

   We have applied for the listing of our shares on The Nasdaq National Market
under the symbol "ESTM."

                        SHARES ELIGIBLE FOR FUTURE SALE

   Prior to this offering, there has been no market for our common stock, and
there can be no assurance that a significant public market for our common stock
will develop or be sustained after this offering. Future sales of substantial
amounts of common stock, including shares issued upon exercise of outstanding
options and warrants, in the public market following this offering could
adversely affect market prices prevailing from time to time and could impair
our ability to raise capital through sale of its equity securities. As
described below, no shares currently outstanding will be available for sale
immediately after this offering because of certain contractual restrictions on
resale. Sales of substantial amounts of our common stock in the public market
after the restrictions lapse could adversely affect the prevailing market price
and our ability to raise equity capital in the future.

   Upon completion of this offering, we will have outstanding            shares
of common stock based upon shares outstanding as of August 10, 1999, assuming
no exercise of the underwriters' over-allotment option and no exercise of
outstanding options or warrants prior to completion of this offering. Of these
shares, the            shares sold in this offering will be freely tradable
without restriction under the Securities Act except for any shares purchased by
our "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 shares as that term is defined in Rule 144. All such restricted
shares are subject to lock-up agreements providing that, with certain limited
exceptions, the stockholder will not offer, sell, contract to sell or otherwise
dispose of any common stock or any securities that are convertible into common
stock for a period of 180 days after the date of this prospectus without the
prior written consent of Donaldson, Lufkin & Jenrette Securities Corporation.
As a result of these lock-up agreements, notwithstanding possible earlier
eligibility for sale under the provisions of Rules 144, 144(k) and 701, none of
these shares will be resellable until 181 days after the date of this
prospectus. Beginning 181 days after the date of this prospectus, approximately
           restricted shares will be eligible for sale in the public market,
all of which are subject to volume limitations under Rule 144, except
           shares eligible for sale under Rule 144(k) and            shares
eligible for sale under Rule 701. In addition, as of August 10, 1999, there
were outstanding options to purchase 1,172,790 shares of common stock, warrants
to purchase 38,797 shares of common stock and warrants to purchase preferred
stock convertible into 21,235 shares of common stock, some of which may be
exercised prior to this offering. All such options and warrants are subject to
lock-up agreements. Donaldson, Lufkin & Jenrette Securities Corporation may, in
its sole discretion and at any time without notice, release all or any portion
of the securities subject to lock-up agreements, however any release shall
apply pro-rata to all stockholders subject to the lock-up agreements.

   In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person who has beneficially owned restricted
shares for at least one year including the holding period of any prior owner
except an affiliate would be entitled to sell within any three-month period a
number of shares that does not exceed 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 during the four
    calendar weeks preceding the filing of a Form 144 with respect to such
    sale.

   Sales under Rule 144 are also subject to certain manner of sale provisions
and notice requirements and to the availability of current public information
about us. Under Rule 144(k), a person who is not deemed to have been an
affiliate of us at any time during the three months preceding a sale, and who
has beneficially owned the shares proposed to be sold for at least two years
including the holding period of any prior owner except an affiliate, is
entitled to sell such shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144.

   Rule 701, as currently in effect, permits resales of shares in reliance upon
Rule 144 but without compliance with certain restrictions, including the
holding period requirement, of Rule 144. Any employee,

                                       58
<PAGE>

officer or director of or consultant to us who purchased shares under a written
compensatory plan or contract may be entitled to rely on the resale provisions
of Rule 701. Rule 701 permits affiliates to sell their Rule 701 shares under
Rule 144 without complying with the holding period requirements of Rule 144.
Rule 701 further provides that non-affiliates may sell such shares in reliance
on Rule 144 without having to comply with the holding period, public
information, volume limitation or notice provisions of Rule 144. All holders of
Rule 701 shares are required to wait until 90 days after the date of this
prospectus before selling such shares. However, all Rule 701 shares are subject
to lock-up agreements and will only become eligible for sale at the earlier of
the expiration of the 180-day lock-up agreements.

   Within 90 days following the effectiveness of this offering, we will file a
Registration Statement on Form S-8 registering 3,994,288 shares of common stock
subject to outstanding options or reserved for future issuance under our stock
plans. As of August 10, 1999, options to purchase a total 1,172,790 shares were
outstanding and 2,821,498 shares were reserved for future issuance under our
stock plans. Common stock issued upon exercise of outstanding vested options or
issued under our purchase plan, other than common stock issued to our
affiliates, is available for immediate resale in the open market.

   Also beginning six months after the date of this offering, holders of
9,619,229 restricted shares will be entitled to certain registration rights for
sale in the public market. See "Description of Capital Stock--Registration
Rights." Registration of such shares under the Securities Act would result in
such shares becoming freely tradable without restriction under the Securities

   The underwriting agreement provides that the obligations of the underwriters
to purchase and accept delivery of the shares of common stock in the offering
are subject to approval by their counsel of legal matters concerning the
offering and to condition precedents that must be satisfied by us. The
underwriters are obligated to purchase and accept delivery of all the shares of
common stock in the offering, other than those shares covered by the over-
allotment option described below, if any are purchased.

   The underwriters initially propose to offer the shares of common stock in
part directly to the public at the initial public offering price set forth on
the cover page of this prospectus and in part to dealers, including the
underwriters, at such price less a concession not in excess of $   per share.
The underwriters may allow, and such dealers may re-allow, to other dealers a
concession not in excess of $   per share. After the initial offering of the
common stock, the public offering price and other selling terms may be changed
by the Representatives at any time without notice. The underwriters do not
intend to confirm sales to any accounts over which they exercise discretionary
authority. An electronic prospectus will be available on the Web site
maintained by DLJdirect Inc., one of the underwriters and an affiliate of
Donaldson, Lufkin & Jenrette Securities Corporation.

   We have granted to the underwriters an option, exercisable for 30 days after
the date of this prospectus, to purchase, from time to time, in whole or in
part, up to an aggregate of additional shares of common stock at the initial
public offering price less underwriting discounts and commission. The
underwriters may exercise the option solely to cover over-allotments, if any,
made in connection with the offering. To the extent that the underwriters
exercise the option, each underwriter will become obligated, subject to
conditions contained in the underwriting agreement, to purchase its pro rata
portion of such additional shares based on the underwriters' percentage
underwriting commitment as indicated in the above table.

   The following table sets forth the compensation payable to the underwriters
by us in connection with the offering:

million and warrants to purchase an aggregate of 21,235 shares of Series C

purchasing an aggregate of 87,294 shares of Series C preferred stock on the
same terms and conditions as the other investors in the private placement,
including price per share.

   We have agreed to indemnify the underwriters against liabilities which may
arise in connection with the offering, including liabilities under the
Securities Act of 1933, or to contribute to payments that the underwriters may
be required to make.

   Our executive officers, directors and certain other stockholders and option
holders have agreed not to:

  .  offer, pledge, sell, contract to sell, sell any option or contract to
     purchase, purchase any option or contract to sell, grant any option,
     right or warrant to purchase, lend, or otherwise transfer or dispose of,
     directly or indirectly, any shares of common stock, other than shares
     acquired in the initial public offering or on the Nasdaq National
     Market, or any securities convertible into or exercisable or
     exchangeable for common stock; or

  .  enter into any swap or other arrangement that transfers to another, in
     whole or in part, any of the economic consequences of ownership of the
     common stock, whether any such transaction described above is to be
     settled by delivery of common stock or other securities, in cash, or
     otherwise.

   Donaldson, Lufkin & Jenrette Securities Corporation may choose to release
some of these shares from such restrictions prior to the expiration of the 180-
day period lock-up period with or without notice, although it has no current
intention of doing so.

   In addition, during such 180-day period, we have also agreed not to file any
registration statement with respect to, and each of our executive officers,
directors and stockholders have agreed not to make any demand for, or exercise
any right with respect to, the registration of any shares of common stock or
any securities convertible into or exercisable or exchangeable for common stock
without the prior written consent of Donaldson, Lufkin & Jenrette Securities
Corporation.

   Prior to the offering, there has been no established trading market for the
common stock. The initial public offering price of the shares of common stock
offered will be determined by negotiation among E-Stamp and the underwriters.
The factors to be considered in determining the initial public offering price
include:

  . the history of and the prospects for the industry in which we compete;

  . our past and present operations;

  . our historical results of operations;

  . our prospects for future operational results;

  . the recent market prices of securities of generally comparable companies;
    and

  . the general condition of the securities markets at the time of the
    offering.

   Other than in the United States, no action has been taken by us or the
underwriters that would permit a public offering of the shares of common stock
offered in any jurisdiction where action for that purpose is required. The
shares of common stock offered may not be offered or sold, directly or
indirectly, nor may this prospectus or any other offering material or
advertisements in connection with the offer and sale of any such shares of
common stock be distributed or published in any jurisdiction, except under
circumstances that will result in compliance with the applicable rules and
regulations of such jurisdiction. Persons into whose possession this prospectus
comes are advised to inform themselves about and observe any restrictions
relating to the offering and the distribution of this prospectus. This
prospectus does not constitute an offer to sell or a solicitation of any offer
to buy any shares of common stock offered in any jurisdiction in which such an
offer or a solicitation is unlawful.

   In connection with the offering, the underwriters may engage in transactions
that stabilize, maintain or otherwise affect the price of the common stock.
Specifically, the underwriters may over-allot the offering, creating a
syndicate short position. The underwriters may bid for and stabilize the price
of the common stock.

                                       61

In addition, the underwriting syndicate may reclaim selling concessions from
syndicate members and selected dealers if they repurchase previously
distributed common stock in syndicate covering transactions, in stabilizing
transactions or otherwise. These activities may stabilize or maintain the
market price of the common stock above independent market levels. The
underwriters are not required to engage in these activities, and may end any of
these activities at any time.

   The underwriters have reserved for sale, at the initial public offering
price, up to shares of the common stock to be sold in the offering for certain
individuals and entities designated by us who have expressed an interest in
purchasing shares in the offering. The number of shares available for sale to
the general public will be reduced to the extent these individuals and entities
purchase these reserved shares. Any reserved shares not so purchased will be
offered by the underwriters to the general public on the same basis as other
shares offered hereby.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Stockholders
E-Stamp Corporation

   We have audited the accompanying balance sheets of E-Stamp Corporation (a
development stage company) as of December 31, 1997 and 1998, and the related
statements of operations, redeemable convertible preferred stock and
stockholders' equity (deficit), and cash flows for each of the three years in
the period ended December 31, 1998. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

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

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of E-Stamp Corporation at
December 31, 1997 and 1998, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1998, in
conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

   (Information for the six months ended June 30, 1998 and 1999 is unaudited)

1. Background and Summary of Significant Policies

   E-Stamp Corporation, a Delaware corporation, was formed on August 23, 1996.
Effective September 1, 1996, Post N Mail, L.L.C., formed on April 26, 1994, was
merged (the "Merger") into E-Stamp Corporation (collectively, the "Company" or
"E-Stamp"). Upon completion of the Merger, all of the assets of Post N Mail,
L.L.C. were acquired by E-Stamp Corporation. The Merger was accounted for as a
combination of entities under common control. Each unit of Post N Mail, L.L.C.
ownership received 5,000 shares of E-Stamp common stock. The financial
statements have been presented to reflect the Merger for all periods presented.
The Company is a development stage company which has devoted substantially all
of its efforts to recruiting personnel to conduct research and product
development and sales and marketing and has not yet generated revenues from the
sale of products.

   The Company has incurred significant losses since inception. Its activities
to date have been financed primarily through private placements of equity
securities. The Company may seek to raise additional capital through the
issuance of debt or equity securities. However, there can be no assurance that
the Company will be able to obtain additional financing on acceptable terms, if
at all.

Nature of Operations

   The Company has developed technology that allows users to apply digital
postage to envelopes, mailing labels, and documents from their personal
computers. This technology, termed the E-Stamp Internet postage solution,
allows authorized users to purchase postage via the Internet and subsequently
print postage from personal computers onto envelopes, mailing labels, and
documents using standard laser and inkjet printers. The Internet postage
solution is designed to print a postmark indicia that can be used as a
replacement for other current forms of postage, including stamps and today's
postmarks generated by postage metering devices. The information generated by
the Internet postage solution will be read by the U.S. Postal Service during
mail processing and allow for routing to intended recipients.

Cash and Cash Equivalents

   The Company considers all highly liquid investments with a remaining
maturity of three months or less when purchased to be cash equivalents. The
Company's cash equivalents were composed of government securities as of
December 31, 1998 and of money market mutual funds and government securities as
of December 31, 1997. The Company's cash and cash equivalents are carried at
cost which approximates market.

Property and Equipment

   Property and equipment are recorded at cost. Additions, improvements, and
renewals that significantly add to the asset value or extend the life of the
asset are capitalized. Expenditures for maintenance and repairs are expensed as
costs are incurred.

   Depreciation and amortization, for financial reporting purposes, are
provided on the straight-line method based upon the estimated useful lives as
follows:

   (Information for the six months ended June 30, 1998 and 1999 is unaudited)


1. Background and Summary of Significant Policies (continued)

Research and Development

   Research and development costs are expensed as they are incurred. Statement
of Financial Accounting Standards No. 86, "Accounting for the Costs of Computer
Software To Be Sold, Leased, or Otherwise Marketed" (FAS 86), requires
capitalization of certain software development costs subsequent to the
establishment of technological feasibility. Based on the Company's product
development process, technological feasibility is established upon completion
of all phases of the detailed product design necessary to establish that the
product can be manufactured to meet all design specifications. Through December
31, 1998, technological feasibility for the Company's primary product was not
established and, therefore, all software research and development costs were
expensed as incurred.

Advertising Costs

   The Company expenses the costs of advertising as incurred except for direct-
response advertising costs meeting certain specific criteria. Advertising
expense was $117,000 for the year ended December 31, 1998. No advertising
expense was recorded for the years ended December 31, 1996 and 1997. To date,
no direct-response advertising costs have been capitalized.

Income Taxes

   The Company computes and records income tax in accordance with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("FAS
109"). Under FAS 109, the liability method is used to calculate deferred taxes.

Stock-Based Compensation

   In accordance with the provisions of Statement of Financial Accounting
Standards No. 123, "Accounting for Stock-Based Compensation" ("FAS 123"), which
the Company adopted in 1996, the Company has elected to follow Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees"
("APB Opinion No. 25"), and related interpretations in accounting for stock
options. Under APB Opinion No. 25, if the exercise price of the Company's
employee and director stock options equals or exceeds the fair value of the
underlying stock on the date of grant, no compensation expense is recognized.
Options granted to consultants are accounted for using the minimum value method
prescribed by FAS 123. (See Note 3 for pro forma disclosures of stock-based
compensation pursuant to FAS 123.)

Use of Estimates

   The Company's management makes estimates and assumptions in the preparation
of its financial statements in conformity with generally accepted accounting
principles. These estimates and assumptions may affect the reported amounts of
assets and liabilities, the disclosure of contingent assets and liabilities as
of the date of the financial statements, and the reported amounts of expenses
during the respective reporting periods. Actual results could differ from those
estimates.

Concentrations

   The Company relies on one manufacturer for the supply and production of its
Internet postage device. The inability of this manufacturer to fulfill the
Company's supply requirements could negatively impact future results.

1. Background and Summary of Significant Policies (continued)

Effect of New Accounting Standards

   Effective January 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130, "Reporting for Comprehensive Income," ("SFAS
130"). SFAS 130 requires disclosures of components of non-stockholder changes
in equity in interim periods and additional disclosures of components of non-
stockholder changes in equity on an annual basis. Adoption of SFAS 130 had no
impact on the Company's results of operations or financial position.

   In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 131, "Disclosures about Segments of an Enterprise and Related Information,"
("SFAS 131"). The Company adopted SFAS 131 effective January 1, 1998. The
adoption of this standard did not have a material effect on the Company's
financial statement disclosures as the Company operates in a single segment.

   In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," ("SFAS 130"). The Company is required to
adopt SFAS 133 for the year ending December 31, 2000. SFAS 133 establishes
methods of accounting for derivative financial instruments and hedging
activities related to those instruments as well as other hedging activities.
Because the Company currently holds no derivative financial instruments and
does not currently engage in hedging activities, adoption of SFAS 133 is
expected to have no material impact on the Company's financial condition or
results of operations.

   In March 1998, the AICPA issued Statement of Position 98-1, "Accounting for
the Costs of Computer Software Developed or Obtained for Internal Use" ("SOP
98-1"). SOP 98-1 requires that entities capitalize certain costs related to
internal use software once certain criteria have been met. The Company adopted
the provisions of SOP 98-1 on January 1, 1999. The adoption of SOP 98-1 has not
had a material impact on our financial position or results of operations.

   The Company will adopt AICPA Statement of Position 97-2, "Software Revenue
Recognition" ("SOP 97-2"), and Statement of Position 98-4, "Deferral of the
Effective Date of a Provision of SOP 97-2, Software Revenue Recognition" ("SOP
98-4") upon its first product revenue transactions. SOP 97-2 and SOP 98-4
provide guidance for recognizing revenue on software transactions and supersede
SOP 91-1, "Software Revenue Recognition." As no revenues have been recognized,
the adoption of SOP 97-2 and SOP 98-4 did not have any impact on the Company's
financial results through December 31, 1998. However, full implementation
guidelines for this standard have not yet been issued. Once available, the
planned revenue accounting practices may need to change and such changes could
affect the Company's future revenues and results of operations. In December
1998, the AICPA issued Statement of Position 98-9, "Modification of SOP 97-2,
Software Revenue Recognition, With Respect to Certain Transactions" ("SOP 98-
9"). SOP 98-9 amends SOP 98-4 to extend the deferral of the application of
certain passages of SOP 97-2 provided by SOP 98-4 through fiscal years
beginning on or before March 15, 1999. All other provisions of SOP 98-9 are
effective for transactions entered into in fiscal years beginning after March
15, 1999. E-Stamp has not yet determined the effect of the final adoption of
SOP 98-9 on its future revenues and results of operations.

Reclassifications

   Certain prior-year amounts have been reclassified to conform with the
current year's presentation.

   (Information for the six months ended June 30, 1998 and 1999 is unaudited)


1. Background and Summary of Significant Policies (continued)

Unaudited Financial Statements

   According to management, the accompanying unaudited financial statements for
the six months ended June 30, 1998 and 1999 and for the period from inception
(April 26, 1994) to June 30, 1999 have been prepared on substantially the same
basis as the audited financial statements and include all adjustments
(consisting of normal recurring adjustments) considered necessary for a fair
presentation of the financial information set forth therein.

Unaudited Pro Forma Information

   If the offering contemplated by this prospectus is consummated, the Series A
and B redeemable convertible preferred stock outstanding as of the closing date
will be converted into shares of the Company's common stock. The pro forma
stockholders' equity as of June 30, 1999 reflects conversion of the outstanding
preferred stock into 6,688,000 shares of common stock. Pro forma net loss per
share is computed as if the outstanding preferred stock had been converted into
common stock on the date of issuance.

2. Line of Credit

   On October 11, 1997, the Company entered into a Loan and Security Agreement
with a bank which allows for a $1,000,000 line of credit to be used for general
business purposes. An amendment dated September 21, 1998 increased the line of
credit to $1,250,000. The Loan and Security Agreement, which expires
September 30, 1999, grants the bank a security interest in all the assets of
the Company except the intellectual property. As of December 31, 1998 and June
30, 1999, no amounts were outstanding under this arrangement; however, a
$35,000 letter of credit required for the Company's California office lease was
secured by this credit facility, leaving the balance of the line of credit of
$1,215,000 available for other purposes. At June 30, 1999, $143,000 was
outstanding on the letter of credit and $1,107,000 was available.

3. Stockholders' Equity

Redeemable Convertible Preferred Stock

   As of December 31, 1998, the Company is authorized to issue 12,000,000
shares of preferred stock in series. Rights and preferences of each series of
preferred stock are to be determined by the Board of Directors. As of December
31, 1998, 2,500,000 and 4,188,000 shares have been designated as Series A and B
redeemable convertible preferred stock, respectively.

   The Series A and B redeemable convertible preferred stock carries an 8%,
noncumulative dividend, payable at the discretion of the Board of Directors.
Additionally, the shares of Series A and B redeemable convertible preferred
stock are convertible into an equal number of shares of common stock (i) at the
option of the holder, (ii) upon the closing of a public offering, as defined,
or (iii) upon the consent of a majority of holders of the Series A and B
redeemable convertible preferred stock. The Company has reserved 2,500,000 and
4,188,000 shares of common stock for the conversion of the Series A and B
redeemable convertible preferred stock, respectively.

   The holders of Series A and B redeemable convertible preferred stock are
entitled to receive noncumulative dividends at the rate of $0.192 and $0.3056
per share, respectively, if declared by the Board of Directors. These dividends
are in preference to any declaration or payment of and dividend on common stock

3. Stockholders' Equity (continued)

of the Company. No dividends have been declared from inception (April 26, 1994)
through December 31, 1998.

   Upon liquidation of the Company, the Series A and B redeemable convertible
preferred stockholders are entitled to a liquidation preference equal to the
original issuance price, plus any declared unpaid dividends, which is superior
to the claim of common stockholders.

   The holders of Series A and B redeemable convertible preferred stock are
entitled to one vote for each share of common stock into which such convertible
preferred stock could be converted.

   At any time after September 3, 2001 but not later than September 3, 2003, a
majority of the holders of Series A redeemable convertible preferred stock can
require the Company to redeem the outstanding Series A redeemable convertible
preferred stock at the redemption price. The redemption price is equal to the
original issuance price of the Series A redeemable convertible preferred stock
plus a 10% compound annual rate of return. The carrying amount of Series A
redeemable convertible preferred stock is being increased by periodic
accretions so that its carrying amount will equal the redemption amount at the
redemption date.

   At any time after July 7, 2002 but not later than July 7, 2004, a majority
of the holders of Series B redeemable convertible preferred stock can require
the Company to redeem the outstanding Series B convertible preferred stock at
the redemption price. The redemption price is equal to the original issuance
price of the Series B redeemable convertible preferred stock plus a 10%
compound annual rate of return. The carrying amount of Series B redeemable
convertible preferred stock is being increased by periodic accretions so that
its carrying amount will equal the redemption amount at the redemption date.

Stock Option Plans

 Stock Option and Restricted Stock Plan

   Effective September 1996, the Company established the 1996 Stock Option and
Restricted Stock Plan (the "Employee Plan"). The Employee Plan expires in
August 2006 and provides for the grant of incentive stock options, nonstatutory
stock options, and restricted stock to employees and consultants of the
Company. An amendment increasing the number of shares thereunder from 2,000,000
to 2,750,000 was approved by the Board of Directors on June 26, 1998. The
Employee Plan is administered by a committee of the Board of Directors. This
committee has the authority to determine the employees and consultants to whom
awards will be made, the amount of the awards, and the other terms and
conditions of the awards. Stock options are limited to ten-year terms, and
options granted through December 31, 1998 generally vest at the rate of 25%
upon the first anniversary of the grant and 6.25% each quarter thereafter. The
exercise price for stock options may not be less than the fair value of the
shares on the date of grant for incentive stock options and is subject to the
discretion of the committee for nonstatutory stock options. Restricted stock
may be granted at no additional cost to recipients. Compensation expense, if
any, equal to the fair value of the restricted stock or stock options granted
in excess of the purchase or exercise price, is recognized over the related
vesting period. A total of 2,750,000 shares of common stock are currently
reserved for issuance pursuant to the Employee Plan. As of December 31, 1998,
options to purchase 1,007,393 shares of common stock at a weighted-average
exercise price of $0.75 per share were outstanding of which 829,730 were
vested, and 163,125 shares of common stock remained available for future grants
under the Employee Plan.

 Nonemployee Directors' Plan

   Also in September 1996, the Company established the 1996 Nonemployee
Director Stock Option Plan (the "Director Plan") which authorizes the issuance
of up to 100,000 shares of common stock. The Director Plan expires in August
2006. The Director Plan is a nondiscretionary stock option plan for nonemployee
directors of the Company, which generally provides for the grant of stock
options for 10,000 shares upon election as a nonemployee director and an
additional grant of stock options for 3,000 shares as of April 1 of each year.
The options are limited to a ten-year term, vest at the rate of 50% per year,
and have an exercise price equal to the fair value of the shares on the date of
grant. A total of 100,000 shares of common stock are currently reserved for
issuance pursuant to the Director Plan. As of December 31, 1998, options to
purchase 15,250 shares of common stock at a weighted-average exercise price of
$0.50 per share were outstanding of which 11,125 were vested, and 84,750 shares
of common stock remained available for future grants under the Director Plan.

   The following is a summary of the combined option transactions under the
Employee Plan and Director Plan for the years ended December 31, 1997 and 1998.

3. Stockholders' Equity (continued)

   During the year ended December 31, 1998, 1,252,920 unvested options were
exercised for cash and in exchange for notes (see Note 7) by various employees
of the Company. At December 31, 1998, 841,757 of these options were still
unvested and subject to repurchase in the event of termination of the
employees.

 Stock-Based Compensation

   During 1995, the Financial Accounting Standards Board adopted Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("FAS 123"), which became effective for the Company's 1996 fiscal
year. FAS 123 requires the Company to disclose the pro forma effect of the
method of accounting prescribed in FAS 123, which would generally require the
Company to record compensation expense equal to the valuation of a stock option
on the grant date.

   The fair value of the Company's stock-based awards to employees was
estimated using the minimum value method and assuming no expected dividends and
the following weighted average assumptions:

<TABLE>

   Risk-free interest rate....................................  6.0%  6.0%  5.0%
   Expected dividend yield.................................... 0.00% 0.00% 0.00%
</TABLE>

   For pro forma purposes, the estimated minimum value of the Company's stock-
based awards to employees is amortized over the options' vesting period. If the
Company had elected to recognize compensation cost based on the fair value of
the options granted at grant date as prescribed by FAS 123, net loss and net
loss per share would have increased to the pro forma amounts indicated in the
table below (in thousands except per share amounts):

</TABLE>

   The weighted-average fair value of options granted in fiscal 1997 and 1998
was $0.19 and $0.14, respectively.

   In 1996, the Company granted equity awards of common stock to certain
employees. Restrictions, as determined by management, lapse from one year to
four years after the grant date. Upon grant, deferred compensation of
approximately $1.1 million, was charged to stockholders' equity and is being
amortized to expense over the periods until the restrictions lapse. In
connection with these restricted shares, amortization charged to expense in
1996 and 1997 was $688,000 and $414,000, respectively $(1,132,000 for the
period from inception to December 31, 1998).

3. Stockholders' Equity (continued)

   The Company has recorded additional deferred stock compensation of
approximately $2,694,000 during the year ended December 31, 1998 and $8,947,000
during the six months ended June 30, 1999 representing the difference between
the exercise price and the deemed fair value, for financial reporting purposes,
of the Company's common stock on the grant date for certain of the Company's
stock options granted to officers and employees. In the absence of a public
market for the Company's common stock, the deemed fair value was based on the
price per share of sales of equity securities to third parties. These amounts
are being amortized by charges to operations over the vesting periods of the
individual stock options using a graded vesting method. Such amortization
expense amounted to approximately $405,000 for the year ended December 31, 1998
and approximately $1,927,000 for the six months ended June 30, 1999.

4. Partnership Agreements

Compaq Software Alliance Agreement

   In July 1998, the Company entered into a three year Software Alliance
Agreement ("Alliance Agreement") with Compaq Computer Corporation ("Compaq").
Under this agreement, Compaq will market our Internet postage solution as part
of their online services and, in exchange, the Company agreed to pay Compaq
royalties.

Strategic Marketing Agreement

   In November, 1998, the Company entered into a strategic marketing agreement
with an Internet service provider (the "Provider") for the promotion of the
Company's internet postage service. The Provider has agreed to deliver a
minimum number of impressions over the approximate 15 month term of the
agreement, commencing on the date the Company receives approval for Phase III
beta testing from the USPS. In exchange for these promotional services, the
Company has agreed to pay the Provider approximately $1.3 million.

5. Income Taxes

   As of December 31, 1998, the Company had federal and state net operating
loss carryforwards of approximately $7,100,000 and $5,700,000 respectively. The
net operating loss carryforwards will expire at various dates beginning in 2004
through 2018, if not utilized.

   Utilization of the net operating losses may be subject to a substantial
annual limitation due to the ownership change limitations provided by the
Internal Revenue Code and similar state provisions. The annual limitation may
result in the expiration of the net operating loss carryforwards before
utilization.

</TABLE>

   FAS 109 provides for the recognition of deferred tax assets if realization
of such assets is more likely than not. Based upon the weight of available
evidence, which includes the Company's historical operating performance and the
reported cumulative net losses in prior years, the Company has provided a full
valuation allowance against its net deferred tax assets.

   The valuation allowance increased by $3,100,000 and $3,800,000 during the
years ended December 31, 1997 and 1998, respectively.

6. Commitments

401(k) Plan

   Effective April 1, 1996, the Company established the E-Stamp Corporation
Benefit Plan (the "Plan"). The Plan provides for a Company match of employee
contributions equal to 50% of employee contributions up to 4% of their
compensation. Employees are eligible to participate in the Plan at the
beginning of the month following the first day of employment. The terms of the
Plan are subject to change as determined by management. The Company made
contributions in 1997 and 1998 of approximately $18,000 and $59,000,
respectively.

Leases

   The Company has various operating leases, the terms of which range from 12
to 60 months. The operating leases are primarily for facilities in Houston,
Texas and Palo Alto, California. Rental expenses related to these leases for
the periods ended December 31, 1996, 1997 and 1998 were $188,000, $411,000 and
$554,000, respectively. During 1997, the Company entered into computer lease
agreements classified as capital leases in the accompanying financial
statements.

   In February 1999, the Company entered into a new sublease pertaining to a
new facility at a monthly rent payment of $71,683 effective April 1, 1999. The
sublease term will end on June 30, 2000. The table below includes the rental
payments from this sublease.

totaled $22,000 and $49,000 at December 31, 1997 and 1998, respectively.

7. Notes Receivable

   On June 12, 1998, the Company received $653,294 of full recourse notes
receivable from employees which bear interest at 6% per annum in consideration
for the exercise of stock options. The interest portion is payable annually or
on or before the 12th day of June, commencing June 12, 1999 and continuing
through June 12, 2003, at which time the entire amount of principal and all
accrued interest then outstanding and remaining unpaid shall become due and
payable in full. The principal is payable in full on the earlier to occur of
June 12, 2003 or 90 days following the termination of employment for any
reason.

   Interest receivable recorded for these notes receivable totaled $21,800 at
December 31, 1998.

8. Net Loss Per Share

   Net loss per share has been computed in accordance with the Statement of
Financial Accounting Standards No. 128, "Earnings Per Share" ("FAS 128"), which
requires disclosure of basic and diluted earnings per share. Basic earnings per
share excludes any dilutive effects of options, shares subject to repurchase,
warrants, and convertible securities. Diluted earnings per share includes the
impact of potentially dilutive securities. The Company's potentially dilutive
securities were antidilutive and therefore were not included in the computation
of weighted-average shares used in computing diluted loss per share. Following
the guidance given by the Securities and Exchange Commission Staff Accounting
Bulletin No. 98, common stock and convertible preferred stock that has been
issued or granted for nominal consideration prior to the anticipated effective
date of the initial public offering date must be included in the calculation of
basic and diluted net loss per common share as if these shares had been
outstanding for all periods presented. To date, the Company has not issued or
granted shares for nominal consideration.

</TABLE>

   The Company has excluded all convertible preferred stock and outstanding
stock options from the calculation of diluted net loss per share because all
such securities are antidilutive for all periods presented. The total number of
shares excluded from the calculations of diluted net loss per share was
659,000, 4,172,000, and 7,711,000 for the years ended December 31, 1996, 1997,
and 1998, respectively, and 2,998,000 and 7,717,000 for the six months ended
June 30, 1998 and 1999, respectively. Such securities, had they been dilutive,
would have been included in the computations of diluted net loss per share
using the treasury stock method.

Strategic Distribution Agreements (unaudited)

   From January 1, 1999 through August 2, 1999, the Company entered into
agreements for online advertising with Yahoo!, Inc., Microsoft Corporation,
Earthlink Operations, Inc. and Excite@Home. Aggregate

9. Subsequent Events (continued)

noncancelable advertising commitments related to these agreements total
approximately $4.4 million, $6.1 million and $2.4 million for the second half
of 1999 and for the years ending December 31, 2000 and 2001, respectively. The
Company has paid $500,000 under these agreements in the six months ended June
30, 1999. The Company could be subject to additional payments under these
agreements if advertising exceeds established levels of page views or generates
and exceeds established levels of new customers.

Pitney Bowes Litigation (unaudited)

   On June 10, 1999, Pitney Bowes filed suit against us in U.S. District Court
alleging infringement of Pitney Bowes patents. The suit alleges that we are
infringing seven patents held by Pitney Bowes related to postage application
systems and seeks treble damages, a preliminary and permanent injunction from
further alleged infringement, attorneys' fees and other unspecified damages. On
July 30, 1999, we filed our answer to Pitney Bowes' complaint in which we deny
all allegations of patent infringement and assert certain affirmative and other
defenses based on statutory and common law grounds, including inequitable
conduct on the part of Pitney Bowes in its procurement of patents in
proceedings before the U.S. Patent and Trademark Office. As part of the answer,
we also brought various counterclaims against Pitney Bowes claiming Pitney
Bowes' violation of Section 2 of the Sherman Act and intentional and tortious
interference with E-Stamp's business relations based, in part, upon our
allegations that Pitney Bowes has unlawfully maintained its monopoly power in
the postage metering market through a scheme to defraud the U.S. Patent and
Trademark Office and its efforts to discourage potential investors and
strategic partners from investing and entering into partnerships with E-Stamp.
Our suit seeks compensatory and treble damages, injunctive relief and recovery
of attorney's fees. We are continuing to investigate the claims against us as
well as infringement by Pitney Bowes of our patents, and may assert additional
defenses or pursue additional counterclaims or independent claims against
Pitney Bowes in the future.

   Pendency of the litigation can be expected to result in significant expenses
to us and the diversion of management time and other resources. If Pitney Bowes
is successful in its claims against us, then we may be hindered or even
prevented from competing in the Internet postage market and our operations
would be severely harmed. For example, the Pitney Bowes suit could result in
limitations on how we implement our solutions, delays and costs associated with
redesigning our solutions and payments of license fees and other payments. An
injunction obtained by Pitney Bowes could eliminate our ability to market
critical products or services.

Bridge Loan Financing (unaudited)

   On July 12, 1999, the Company entered into bridge loan financing arrangement
with a financial institution under which the Company borrowed $5.0 million.
Amounts borrowed under the arrangement bear interest at a rate of 13% per
annum. In connection with this financing, the Company granted the lender
warrants to purchase 38,797 shares of common stock with an exercise price of
$10.31 per share. These warrants expire in July, 2004. The Company anticipates
recording the fair value of these warrants of approximately $85,000 as interest
expense over the period the loan is outstanding. The Company borrowed $5.0
million in July, 1999 under the facility and fully repaid the outstanding
balance in August, 1999.

Employee Option Grants (unaudited)

   From July 1, 1999 to July 27, 1999, options to purchase 626,000 shares were
issued to employees pursuant to the 1996 Stock Option Plan with an exercise
price of $1.50 per share. The Company estimates that

additional deferred compensation of $4.5 million will be recorded as a result
of these option grants and amortized to compensation expense in accordance with
the Company's policy.

1996 Stock Plan (unaudited)

   In February 1999, the board of directors approved an amendment increasing
the number of shares reserved for issuance under the 1996 Stock Plan from
2,750,000 to 4,750,000 subject to shareholder approval. The shareholders
approved the increase in April 1999.

1999 Stock Plan (unaudited)

   In August 1999, the board of directors approved the 1999 Stock Plan subject
to shareholder approval. A total of 2,000,000 shares of common stock are
reserved for issuance under the plan.

1999 Employee Stock Purchase Plan (unaudited)

   In August 1999, the board of directors approved the 1999 Employee Stock
Purchase Plan subject to shareholder approval. A total of 500,000 shares of
common stock has been reserved for issuance under the 1999 Purchase Plan. The
1999 Purchase Plan permits eligible employees to acquire shares of the
Company's common stock through periodic payroll deductions of up to 15% of
total compensation. No more than 5,000 shares may be purchased on any purchase
date per employee. Each offering period will have a maximum duration of 24
months. The price at which the common stock may be purchased is 85% of the
lesser of the fair market value of the Company's common stock on the first day
of the applicable offering period or on the last day of the respective purchase
period. The initial offering period will commence on the effectiveness of the
initial public offering and will end on the last trading day on or before
November 14, 2001.

1999 Director Option Plan (unaudited)

   In August 1999, the board of directors approved the 1999 Option Plan subject
to shareholder approval. A total of 300,000 shares of common stock are reserved
for issuance under the Plan.

Sales of Stock

   In August 1999, the Company issued 2,931,229 shares of Series C redeemable
convertible preferred stock at $10.31 per share. Series C redeemable
convertible preferred stock carries an 8%, noncumulative dividend, is
convertible into one share of common stock and has other rights and preferences
similar to those described for Series A and B convertible stock in Note 3. In
connection with the sale of Series C redeemable convertible preferred stock,
the Company committed to issue 21,235 warrants to purchase shares of Series C
redeemable convertible preferred stock at $10.31 per share to Donaldson Lufkin
& Jenrette Securities Corporation as placement agent.

Item 14. Indemnification of Directors and Officers

   Section 145 of the Delaware General Corporation Law permits a corporation to
include in its charter documents, and in agreements between the corporation and
its directors and officers, provisions expanding the scope of indemnification
beyond that specifically provided by the current law.

   Article IX of the Registrant's Restated Certificate of Incorporation
provides for the indemnification of directors to the fullest extent permissible
under Delaware law.

   Article VI of the Registrant's Bylaws provides for the indemnification of
officers, directors and third parties acting on behalf of the Registrant if
such person acted in good faith and in a manner reasonably believed to be in
and not opposed to the best interest of the Registrant, and, with respect to
any criminal action or proceeding, the indemnified party had no reason to
believe his or her conduct was unlawful.

   The Registrant has entered into indemnification agreements with its
directors and executive officers, in addition to indemnification provided for
in the Registrant's Bylaws, and intends to enter into indemnification
agreements with any new directors and executive officers in the future.

   The Underwriting Agreement (Exhibit 1.1 hereto) provides for indemnification
by the Underwriters of the registrant and its executive officers and directors,
and by the registrant of the underwriters for certain liabilities, including
liabilities arising under the Securities Act, in connection with matters
specifically provided in writing by the Underwriters for inclusion in the
Registration Statement.

Item 15. Recent Sales of Unregistered Securities

   During the past three years, the Registrant has issued unregistered
securities to a limited number of persons as described below:

   (a) On September 3, 1997, we issued an aggregate of 2,500,000 shares of our
Series A Preferred Stock to certain accredited investors for an aggregate
offering price of $6,000,000.

   On July 7, 1998, we issued an aggregate of 4,188,000 shares of our Series B
Preferred Stock to certain accredited investors for an aggregate offering price
of $16,000,000.

                                      II-1
<PAGE>

   On July 26, 1999, we granted a warrant to a lender to purchase up to 38,797
shares of Common Stock at $10.31 per share.

   On August 10, 1999, we issued an aggregate of 2,931,229 shares of our Series
C Preferred Stock to certain accredited investors for an aggregate offering
price of $30,220,971.

   On August 10, 1999, we granted a warrant to our placement agent to purchase
up to 21,235 shares of Series C Preferred Stock at $10.31 per share.

   From January 1996 to August 1999, we have granted options to purchase an
aggregate of 5,889,175 shares of common stock to our directors, executive
officers, employees and consultants at a weighted exercise price of $1.05. As
of August 10, 1999, options to purchase 3,898,735 shares at a weighted exercise
price of $.87 per share had been exercised.

   The foregoing transactions were effected under Section 4(2) of the
Securities Act.

   (b) As of August 10, 1999, an aggregate of 3,555,712 shares of common stock
had been issued upon exercise of options under the Registrant's 1996 Stock
Option and Restricted Stock Plan. Except as indicated above, none of the
foregoing transactions involved any underwriters, underwriting discounts or
commissions, or any public offering, and the Registrant believes that each
transaction was exempt from the registration requirements of the Securities Act
by virtue of Section 4(2) thereof, Regulation D promulgated thereunder or Rule
701 pursuant to compensatory benefit plans and contracts relating to
compensation as provided under such Rule 701. The recipients in such
transactions represented their intention to acquire the securities for
investment only and not with a view to or for sale in connection with any
distribution thereof, and appropriate legends were affixed to the share
certificates and instruments issued in such transactions. All recipients had
adequate access, through their relationships with the Registrant, to
information about the Registrant.

   Schedules not listed above have been omitted because the information
required to be set forth therein is not applicable or is shown in the financial
statements or notes thereto.

Item 17. Undertakings

   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.

   Insofar as indemnification by the Registrant for liabilities arising under
the Securities Act may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the provisions referenced in Item 14 of
this Registration Statement 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 a
director, officer or controlling person in connection with the securities being
registered hereunder, the Registrant will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.

   The undersigned Registrant hereby undertakes that:

   (1) For purposes of determining any liability under the Securities Act, the
information omitted from the form of Prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.

   (2) For the purpose of determining any liability under the Securities Act,
each post-effective amendment that contains a form of Prospectus shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

Dear Sirs:

"Underwriters").   The Company also proposes to issue and sell to the several
Underwriters not more than an additional _______ shares of its common stock,
$0.001 par value (the "Additional Shares"), if requested by the Underwriters as
provided in Section 2 hereof.   The Firm Shares and the Additional Shares are
hereinafter referred to collectively as the "Shares". The shares of common stock
of the Company to be outstanding after giving effect to the sales contemplated
hereby are hereinafter referred to as the "Common Stock".

                                       1

     Section 1.  Registration Statement and Prospectus.  The Company has
prepared and filed with the Securities and Exchange Commission (the
"Commission") in accordance with the provisions of the Securities Act of 1933,
as amended, and the rules and regulations of the Commission thereunder
(collectively, the "Act"), a registration statement on Form S-1, including a
prospectus, relating to the Shares.  The registration statement, as amended at
the time it became effective, including the information (if any) deemed to be
part of the registration statement at the time of effectiveness pursuant to Rule
430A under the Act, is hereinafter referred to as the "Registration Statement";
and the prospectus in the form first used to confirm sales of Shares is
hereinafter referred to as the "Prospectus". If the Company has filed or is
required pursuant to the terms hereof to file a registration statement pursuant
to Rule 462(b) under the Act registering additional shares of Common Stock (a
"Rule 462(b) Registration Statement"), then, unless otherwise specified, any
reference herein to the term "Registration Statement" shall be deemed to include
such Rule 462(b) Registration Statement.

     Section 2.  Agreements to Sell and Purchase and Lock-Up Agreements. On the
basis of the representations and warranties contained in this Agreement, and
subject to its terms and conditions, the Company agrees to issue and sell, and
each Underwriter agrees, severally and not jointly, to purchase from the Company
at a price per Share of $______ (the "Purchase Price") the number of Firm Shares
set forth opposite the name of such Underwriter in Schedule I hereto.

     On the basis of the representations and warranties contained in this
Agreement, and subject to its terms and conditions, the Company agrees to issue
and sell the Additional Shares and the Underwriters shall have the right to
purchase, severally and not jointly, up to _______ Additional Shares from the
Company at the Purchase Price.   Additional Shares may be purchased solely for
the purpose of covering over-allotments made in connection with the offering of
the Firm Shares.   The Underwriters may exercise their right to purchase
Additional Shares in whole or in part from time to time by giving written notice
thereof to the Company within 30 days after the date of this Agreement.  You
shall give any such notice on behalf of the Underwriters and such notice shall
specify the aggregate number of Additional Shares to be purchased pursuant to
such exercise and the date for payment and delivery thereof, which date shall be
a business day (i) no earlier than two business days after such notice has been
given (and, in any event, no earlier than the Closing Date (as hereinafter
defined)) and (ii) no later than ten business days after such notice has been
given.   If any Additional Shares are to be purchased, each Underwriter,
severally and not jointly, agrees to purchase from the Company the number of
Additional Shares (subject to such adjustments to eliminate fractional shares as
you may determine) which bears the same proportion to the total number of
Additional Shares to be purchased from the Company as the number of Firm Shares
set forth opposite the name of such Underwriter in Schedule I bears to the total
number of Firm Shares.

material adverse effect on the business, prospects, financial condition or
results of operations of the Company and its subsidiaries, taken as a whole.

       (e)  There are no outstanding subscriptions, rights, warrants, options,

Company's subsidiaries have been duly authorized and validly issued and are
fully paid and non-assessable, and are owned by the Company, directly or

       (h)  The authorized capital stock of the Company conforms as to legal
matters to the description thereof contained in the Prospectus.

       (i)  Neither the Company nor any of its subsidiaries is in violation of
its respective charter or by-laws or in default in the performance of any
obligation, agreement, covenant or condition contained in any indenture, loan
agreement, mortgage, lease or other agreement or instrument that is material to
the Company and its subsidiaries, taken as a whole, to which the Company or any
of its subsidiaries is a party or by which the Company or any of its
subsidiaries or their respective property is bound.

       (j)  The execution, delivery and performance of this Agreement by the
Company, the compliance by the Company with all the provisions hereof and the
consummation of the transactions contemplated hereby will not (i) require any
consent, approval, authorization or other order of, or qualification with,  any
court or governmental body or agency (except such as may be required under the
securities or Blue Sky laws of the various states), (ii) conflict with or
constitute a breach of any of the terms or provisions of, or a default under,
the charter or by-laws of the Company or any of its subsidiaries or any
indenture, loan agreement, mortgage, lease or other agreement or instrument that
is material to the Company and its subsidiaries, taken as a whole, to which the
Company or any of its subsidiaries is a party or by which the Company or any of
its subsidiaries or their respective property is bound, (iii) violate or
conflict with any applicable law or any rule, regulation, judgment, order or
decree of any court or any governmental body or agency having jurisdiction over
the Company, any of its subsidiaries or their respective property or (iv) result
in the suspension, termination or revocation of any Authorization (as defined
below) of the Company or any of its subsidiaries or any other impairment of the
rights of the holder of any such Authorization.

       (k)  There are no legal or governmental proceedings pending or threatened
to which the Company or any of its subsidiaries is or could be a party or to
which any of their respective property is or could be subject that are required
to be described in the Registration Statement or the Prospectus and are not so
described; nor are there any statutes, regulations, contracts or other documents
that are required to be described in the Registration Statement or the
Prospectus or

                                       9
<PAGE>

to be filed as exhibits to the Registration Statement that are not so described
or filed as required.

       (l)  Neither the Company nor any of its subsidiaries has violated any
foreign, federal, state or local law or regulation relating to the protection of
human health and safety, the environment or hazardous or toxic substances or
wastes, pollutants or contaminants ("Environmental Laws"), any provisions of the
Employee Retirement Income Security Act of 1974, as amended, or any provisions
of the Foreign Corrupt Practices Act, or the rules and regulations promulgated
thereunder, except for such violations which, singly or in the aggregate, would
not have a material adverse effect on the business, prospects, financial
condition or results of operation of the Company and its subsidiaries, taken as
a whole.

       (m)  Each of the Company and its subsidiaries has such permits, licenses,
consents, exemptions, franchises, authorizations and other approvals (each, an
"Authorization") of, and has made all filings with and notices to, all
governmental or regulatory authorities and self-regulatory organizations and all
courts and other tribunals, including, without limitation, under any applicable
Environmental Laws, as are necessary to own, lease, license and operate its
respective properties and to conduct its business, except where the failure to
have any such Authorization or to make any such filing or notice would not,
singly or in the aggregate, have a material adverse effect on the business,
prospects, financial condition or results of operations of the Company and its
subsidiaries, taken as a whole.  Each such Authorization is valid and in full
force and effect and each of the Company and its subsidiaries is in compliance
with all the terms and conditions thereof and with the rules and regulations of
the authorities and governing bodies having jurisdiction with respect thereto;
and no event has occurred (including, without limitation, the receipt of any
notice from any authority or governing body) which allows or, after notice or
lapse of time or both, would allow, revocation, suspension or termination of any
such Authorization or results or, after notice or lapse of time or both, would
result in any other impairment of the rights of the holder of any such
Authorization; and such Authorizations contain no restrictions that are
burdensome to the Company or any of its subsidiaries; except where such failure
to be valid and in full force and effect or to be in compliance, the occurrence
of any such event or the presence of any such restriction would not, singly or
in the aggregate, have a material adverse effect on the business, prospects,
financial condition or results of operations of the Company and its
subsidiaries, taken as a whole.

       (n)  There are no costs or liabilities associated with Environmental Laws
(including, without limitation, any capital or operating expenditures required
for clean-up, closure of properties or compliance with Environmental Laws or any
Authorization, any related constraints on operating activities and any potential
liabilities to third parties) which would, singly or in the aggregate, have a
material

                                       10
<PAGE>

adverse effect on the business, prospects, financial condition or results of
operations of the Company and its subsidiaries, taken as a whole.

the Company.

the Company and its subsidiaries as required by the Act.

       (q)  The consolidated financial statements included in the Registration

with related schedules and notes, present fairly the consolidated financial
position, results of operations and changes in financial position of the Company
and its subsidiaries on the basis stated therein at the respective dates or for

except as disclosed therein; the supporting schedules, if any, included in the
Registration Statement present fairly in accordance with generally accepted
accounting principles the information required to be stated therein; and the
other financial and statistical information and data set forth in the
Registration Statement and the Prospectus (and any amendment or supplement
thereto) are, in all material respects, accurately presented and prepared on a
basis consistent with such financial statements and the books and records of the
Company.

       (r)  The Company is not and, after giving effect to the offering and sale

       (s)  There are no contracts, agreements or understandings between the
Company and any person granting such person the right to require the Company to
file a registration statement under the Act with respect to any securities of
the Company or to require the Company to include such securities with the Shares
registered pursuant to the Registration Statement.

       (t)  Since the respective dates as of which information is given in the
Prospectus other than as set forth in the Prospectus (exclusive of any
amendments or supplements thereto subsequent to the date of this Agreement), (i)

a prospective material adverse change in the condition, financial or otherwise,

liability or obligation, direct or contingent.

     (u)  The Company has complied with all provisions of Section 517.075,

representation and warranty by the Company to the Underwriters as to the matters
covered thereby.


Section 7.  Indemnification.  (a) The Company agrees to indemnify and hold
harmless each Underwriter, its directors, its officers and each person, if any,
who controls any Underwriter within the meaning of Section 15 of the Act or
Section 20 of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), from and against any and all losses, claims, damages, liabilities and
judgments (including, without limitation, any legal or other expenses incurred
in connection with investigating or defending any matter, including any action,
that could give rise to any such losses, claims, damages, liabilities or
judgments) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement (or any amendment
thereto), the Prospectus (or any amendment or supplement thereto) or any
preliminary prospectus, or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as such losses, claims,
damages, liabilities or judgments are caused by any such untrue statement or
omission or alleged untrue statement or omission based upon information relating
to any Underwriter furnished in writing to the Company by such Underwriter
through you expressly for use therein; provided, however, that the foregoing
indemnity agreement with respect to any preliminary prospectus shall not inure
to the benefit of any Underwriter who failed to deliver a Prospectus, as then
amended or supplemented, (so long as the Prospectus and any amendments or
supplements thereto was provided by the Company to the several Underwriters in
the requisite quantity and on a timely basis to permit proper delivery on or
prior to the Closing Date) to the person asserting any losses, claims, damages,
liabilities or judgments caused by any untrue statement or alleged untrue
statement of a material fact contained in such preliminary prospectus, or caused
by any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading, if
such material misstatement or omission or alleged material misstatement or
omission was cured in the Prospectus, as so amended or supplemented, and such
Prospectus was required by law to be delivered at or prior to the written
confirmation of sale to such person.

       (b)  Each Underwriter agrees, severally and not jointly, to indemnify and
hold harmless the Company, its directors, its officers who sign the Registration
Statement and each person, if any, who controls the Company within the meaning

                                       12
<PAGE>

of Section 15 of the Act or Section 20 of the Exchange Act, to the same extent
as the foregoing indemnity from the Company to such Underwriter but only with
reference to information relating to such Underwriter furnished in writing to
the Company by such Underwriter through you expressly for use in the
Registration Statement (or any amendment thereto), the Prospectus (or any
amendment or supplement thereto) or any preliminary prospectus.

     (c)   In case any action shall be commenced involving any person in respect
of which indemnity may be sought pursuant to Section 7(a) or 7(b) (the
"indemnified party"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying party") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 7(a) and 7(b), the Underwriter shall not be required to assume
the defense of such action pursuant to this Section 7(c), but may employ
separate counsel and participate in the defense thereof, but the fees and
expenses of such counsel, except as provided below, shall be at the expense of
such Underwriter).   Any indemnified party shall have the right to employ
separate counsel in any such action and participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of the indemnified
party unless (i) the employment of such counsel shall have been specifically
authorized in writing by the indemnifying party, (ii) the indemnifying party
shall have failed to assume the defense of such action or employ counsel
reasonably satisfactory to the indemnified party or (iii) the named parties to
any such action (including any impleaded parties) include both the indemnified
party and the indemnifying party, and the indemnified party shall have been
advised by such counsel that there may be one or more legal defenses available
to it which are different from or additional to those available to the
indemnifying party (in which case the indemnifying party shall not have the
right to assume the defense of such action on behalf of the indemnified party).
In any such case, the indemnifying party shall not, in connection with any one
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys (in
addition to any local counsel) for all indemnified parties and all such fees and
expenses shall be reimbursed as they are incurred.  Such firm shall be
designated in writing by Donaldson, Lufkin & Jenrette Securities Corporation, in
the case of parties indemnified pursuant to Section 7(a), and by the Company, in
the case of parties indemnified pursuant to Section 7(b). The indemnifying party
shall indemnify and hold harmless the indemnified party from and against any and
all losses, claims, damages, liabilities and judgments by reason of any
settlement of any action (i) effected with its written consent or (ii) effected
without its written consent if the settlement is entered into more than twenty
business days after the indemnifying party shall have received a request from
the indemnified party for reimbursement for the fees and expenses of counsel (in
any

                                       13
<PAGE>

case where such fees and expenses are at the expense of the indemnifying party)
and, prior to the date of such settlement, the indemnifying party shall have
failed to comply with such reimbursement request. No indemnifying party shall,
without the prior written consent of the indemnified party, effect any
settlement or compromise of, or consent to the entry of judgment with respect
to, any pending or threatened action in respect of which the indemnified party
is or could have been a party and indemnity or contribution may be or could have
been sought hereunder by the indemnified party, unless such settlement,
compromise or judgment (i) includes an unconditional release of the indemnified
party from all liability on claims that are or could have been the subject
matter of such action and (ii) does not include a statement as to or an
admission of fault, culpability or a failure to act, by or on behalf of the
indemnified party.

       (d)  To the extent the indemnification provided for in this Section 7 is
unavailable to an indemnified party or insufficient in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities and judgments (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and the Underwriters on the other hand from the offering
of the Shares or (ii) if the allocation provided by clause 7(d)(i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause 7(d)(i) above but also the
relative fault of the Company on the one hand and the Underwriters on the other
hand in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or judgments, as well as any other relevant
equitable considerations.  The relative benefits received by the Company on the
one hand and the Underwriters on the other hand shall be deemed to be in the
same proportion as the total net proceeds from the offering (after deducting
underwriting discounts and commissions, but before deducting expenses) received
by the Company, and the total underwriting discounts and commissions received by
the Underwriters, bear to the total price to the public of the Shares, in each
case as set forth in the table on the cover page of the Prospectus.  The
relative fault of the Company on the one hand and the Underwriters on the other
hand shall be determined by reference to, among other things, whether the untrue
or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
or the Underwriters and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

     The Company and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Section 7(d) were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to in the immediately preceding paragraph.
The amount

                                       14
<PAGE>

paid or payable by an indemnified party as a result of the losses, claims,
damages, liabilities or judgments referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses incurred by such indemnified party in
connection with investigating or defending any matter, including any action,
that could have given rise to such losses, claims, damages, liabilities or
judgments. Notwithstanding the provisions of this Section 7, no Underwriter
shall be required to contribute any amount in excess of the amount by which the
total price at which the Shares underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations to contribute
pursuant to this Section 7(d) are several in proportion to the respective number
of Shares purchased by each of the Underwriters hereunder and not joint.

     (e)  The remedies provided for in this Section 7 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
indemnified party at law or in equity.

     Section 8.  Conditions of Underwriters' Obligations.  The several
obligations of the Underwriters to purchase the Firm Shares under this Agreement
are subject to the satisfaction of each of the following conditions:

     (a)  All the representations and warranties of the Company contained in
this Agreement shall be true and correct on the Closing Date with the same force
and effect as if made on and as of the Closing Date.

     (b)  If the Company is required to file a Rule 462(b) Registration
Statement after the effectiveness of this Agreement, such Rule 462(b)
Registration Statement shall have become effective by 10:00 P.M., New York City
time, on the date of this Agreement; and no stop order suspending the
effectiveness of the Registration Statement shall have been issued and no
proceedings for that purpose shall have been commenced or shall be pending
before or contemplated by the Commission.

     (c)  You shall have received on the Closing Date a certificate dated the
Closing Date, signed by Robert H. Ewald and Anthony H. Lewis, Jr., in their
capacities as the President and Chief Executive Officer and Vice President and
Chief Financial Officer of the Company, confirming the matters set forth in
Sections 6(t), 8(a) and 8(b) and that the Company has complied with all of the
agreements and satisfied all of the conditions herein contained and required
to be complied with or satisfied by the Company on or prior to the Closing
Date.

     (d)  Since the respective dates as of which information is given in the

                                       15
<PAGE>

Prospectus other than as set forth in the Prospectus (exclusive of any
amendments or supplements thereto subsequent to the date of this Agreement), (i)
there shall not have occurred  any change or any development involving a
prospective change in the condition, financial or otherwise, or the earnings,
business, management or operations of the Company and its subsidiaries, taken as
a whole, (ii) there shall not have been any change or any development involving
a prospective change in the capital stock or in the long-term debt of the
Company or any of its subsidiaries and (iii) neither the Company nor any of its
subsidiaries shall have incurred any liability or obligation, direct or
contingent, the effect of which, in any such case described in clause 8(d)(i),
8(d)(ii) or 8(d)(iii), in your judgment, is material and adverse and, in your
judgment, makes it impracticable to market the Shares on the terms and in the
manner contemplated in the Prospectus.

       (e)  You shall have received on the Closing Date an opinion (satisfactory
to you and counsel for the Underwriters), dated the Closing Date, of Wilson
Sonsini Goodrich & Rosati, counsel for the Company, to the effect that:

               (i)     each of the Company and its subsidiaries has been duly
     incorporated, is validly existing as a corporation in good standing under

     qualified and is in good standing as a foreign corporation authorized to do

     ownership or leasing of property requires such qualification, except where
     the failure to be so qualified would not have a material adverse effect on
     the business, prospects, financial condition or results of operations of
     the Company and its subsidiaries, taken as a whole;

               (iii)   all the outstanding shares of capital stock of the

     subsidiaries is a party or by which the Company or any of its subsidiaries
     or their respective property is bound;

               (xi)    the execution, delivery and performance of this Agreement
     by the Company, the compliance by the Company with all the provisions

     Corrupt Practices Act, or the rules and regulations promulgated thereunder,
     except for such violations which, singly or in the aggregate, would not
     have a material adverse effect on the business, prospects, financial
     condition or results of operation of the Company and its subsidiaries,
     taken as a whole;

               (xiv)   each of the Company and its subsidiaries has such
     Authorizations of, and has made all filings with and notices to, all
     governmental or regulatory authorities and self-regulatory organizations
     and all courts and other tribunals, including, without limitation, under
     any applicable Environmental Laws, as are necessary to own, lease, license
     and operate its respective properties and to conduct its business, except
     where the failure to have any such Authorization or to make any such filing
     or notice would not, singly or in the aggregate, have a material adverse
     effect on the business, prospects, financial condition or results of
     operations of the Company and its subsidiaries, taken as a whole;  each
     such Authorization is valid and in full force and effect and each of the
     Company and its subsidiaries is in compliance with all the terms and
     conditions thereof and with the rules and regulations of the authorities
     and governing bodies having jurisdiction with respect thereto; and no event
     has occurred (including, without limitation, the receipt of any notice from
     any authority or governing body) which allows or, after notice or lapse of
     time or both, would allow, revocation, suspension or termination of any
     such Authorization or results or, after notice or lapse of time or both,
     would result in any other impairment of the rights of the holder of any
     such Authorization; and such Authorizations contain no restrictions that

                                       18
<PAGE>

     are burdensome to the Company or any of its subsidiaries; except where such
     failure to be valid and in full force and effect or to be in compliance,
     the occurrence of any such event or the presence of any such restriction
     would not, singly or in the aggregate, have a material adverse effect on
     the business, prospects, financial condition or results of operations of
     the Company and its subsidiaries, taken as a whole;

               (xv)    the Company is not and, after giving effect to the
     offering and sale of the Shares and the application of the proceeds thereof
     as described in the Prospectus, will not be, an "investment company" as
     such term is defined in the Investment Company Act of 1940, as amended;

               (xvi)   to the best of such counsel's knowledge after due
     inquiry, there are no contracts, agreements or understandings between the
     Company and any person granting such person the right to require the
     Company to file a registration statement under the Act with respect to any
     securities of the Company or to require the Company to include such
     securities with the Shares registered pursuant to the Registration
     Statement; and

               (xvii)  (A) the Registration Statement and the Prospectus and any
     supplement or amendment thereto (except for the financial statements and
     other financial data included therein as to which no opinion need be
     expressed) comply as to form with the Act, (B) such counsel has no reason
     to believe that at the time the Registration Statement became effective or
     on the date of this Agreement, the Registration Statement and the
     prospectus included therein (except for the financial statements and other
     financial data as to which such counsel need not express any belief)
     contained any untrue statement of a material fact or omitted to state a
     material fact required to be stated therein or necessary to make the
     statements therein not misleading and (C) such counsel has no reason to
     believe that the Prospectus, as amended or supplemented, if applicable
     (except for the financial statements and other financial data, as
     aforesaid) contains any untrue statement of a material fact or omits to
     state a material fact necessary in order to make the statements therein, in
     the light of the circumstances under which they were made, not misleading.

above shall be rendered to you at the request of the Company and shall so state
therein.

to you and counsel for the Underwriters), dated the Closing Date, of Howrey &

caption "Risk Factors--Intellectual property infringement claims, including
claims asserted by Pitney Bowes against us, could prevent or hinder our
ability to sell Internet postage" and in the first two paragraphs under the
caption "Business--Legal Proceedings" (collectively the "IP Sections") contain
accurate descriptions of the Company's Intellectual Property and, insofar as

conclusions, are accurate and fairly present such summaries, matters of law
and legal conclusions;

         (ii)  (A) the IP Sections of the Registration Statement and the
Prospectus and any supplement or amendment thereto comply as to form with the
Act, (B) such counsel has no reason to believe that at the time the Registration
Statement became effective or on the date of this Agreement, the IP Sections of
the Registration Statement and the prospectus included therein contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements in the IP Sections not
misleading and (C) such counsel has no reason to believe that the IP Sections of
the Prospectus, as amended or supplemented, if applicable contains any untrue
statement of a material fact or omits to state a material fact necessary in
order to make such statements, in the light of the circumstances under which
they were made, not misleading.

and "Underwriting") and 8(e)(xvii).

     In giving such opinions with respect to the matters covered by Section
8(e)(xvii) and (ee)(ix) Wilson Sonsini Goodrich & Rosati, Howrey & Simon and
Pillsbury Madison & Sutro LLP may state that their opinion and belief are based

<PAGE>

     (j)  The Company shall not have failed on or prior to the Closing Date to
perform or comply with any of the agreements herein contained and required to be
performed or complied with by the Company on or prior to the Closing Date.

     The several obligations of the Underwriters to purchase any Additional
Shares hereunder are subject to the delivery to you on the applicable Option
Closing Date of such documents as you may reasonably request with respect to the
good standing of the Company, the due authorization and issuance of such
Additional Shares and other matters related to the issuance of such Additional
Shares.

     Section 9.  Effectiveness of Agreement and Termination.  This Agreement
shall become effective upon the execution and delivery of this Agreement by the
parties hereto.

     This Agreement may be terminated at any time on or prior to the Closing
Date by you by written notice to the Company if any of the following has
occurred:  (i) any outbreak or escalation of hostilities or other national or
international calamity or crisis or change in economic conditions or in the
financial markets of the United States or elsewhere that, in your judgment, is
material and adverse and, in your judgment, makes it impracticable to market the
Shares on the terms and in the manner contemplated in the Prospectus, (ii) the
suspension or material limitation of trading in securities or other instruments
on the New York Stock Exchange, the American Stock Exchange, the Chicago Board
of Options Exchange, the Chicago Mercantile Exchange, the Chicago Board of Trade
or the Nasdaq National Market or limitation on prices for securities or other
instruments on any such exchange or the Nasdaq National Market, (iii) the
suspension of trading of any securities of the Company on any exchange or in the
over-the-counter market, (iv) the enactment, publication, decree or other
promulgation of any federal or state statute, regulation, rule or order of any

prospects, financial condition or results of operations of the Company and its
subsidiaries, taken as a whole, (v) the declaration of a banking moratorium by
either federal or New York State authorities or (vi) the taking of any action by
any federal, state or local government or agency in respect of its monetary or
fiscal affairs which in your opinion has a material adverse effect on the
financial markets in the United States.

     If on the Closing Date or on an Option Closing Date, as the case may be,
any one or more of the Underwriters shall fail or refuse to purchase the Firm
Shares or Additional Shares, as the case may be, which it has or they have
agreed to purchase hereunder on such date and the aggregate number of Firm
Shares or Additional Shares, as the case may be, which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase is not more
than one-tenth of the total number of Firm Shares or Additional Shares, as the
case may be, to be purchased on such date by all Underwriters, each non-
defaulting Underwriter shall

                                       21
<PAGE>

be obligated severally, in the proportion which the number of Firm Shares set
forth opposite its name in Schedule I bears to the total number of Firm Shares
which all the non-defaulting Underwriters have agreed to purchase, or in such
other proportion as you may specify, to purchase the Firm Shares or Additional
Shares, as the case may be, which such defaulting Underwriter or Underwriters
agreed but failed or refused to purchase on such date; provided that in no event
shall the number of Firm Shares or Additional Shares, as the case may be, which
any Underwriter has agreed to purchase pursuant to Section 2 hereof be increased
pursuant to this Section 9 by an amount in excess of one-ninth of such number of
Firm Shares or Additional Shares, as the case may be, without the written
consent of such Underwriter. If on the Closing Date any Underwriter or
Underwriters shall fail or refuse to purchase Firm Shares and the aggregate
number of Firm Shares with respect to which such default occurs is more than
one-tenth of the aggregate number of Firm Shares to be purchased by all
Underwriters and arrangements satisfactory to you and the Company for purchase
of such Firm Shares are not made within 48 hours after such default, this
Agreement will terminate without liability on the part of any non-defaulting
Underwriter and the Company. In any such case which does not result in
termination of this Agreement, either you or the Company shall have the right to
postpone the Closing Date, but in no event for longer than seven days, in order
that the required changes, if any, in the Registration Statement and the
Prospectus or any other documents or arrangements may be effected. If, on an
Option Closing Date, any Underwriter or Underwriters shall fail or refuse to
purchase Additional Shares and the aggregate number of Additional Shares with
respect to which such default occurs is more than one-tenth of the aggregate
number of Additional Shares to be purchased on such date, the non-defaulting
Underwriters shall have the option to (i) terminate their obligation hereunder
to purchase such Additional Shares or (ii) purchase not less than the number of
Additional Shares that such non-defaulting Underwriters would have been
obligated to purchase on such date in the absence of such default. Any action
taken under this paragraph shall not relieve any defaulting Underwriter from
liability in respect of any default of any such Underwriter under this
Agreement.

     Section 10.  Miscellaneous.  Notices given pursuant to any provision of
this Agreement shall be addressed as follows: (i) if to the Company, to E-Stamp
Corporation, 2855 Campus Drive, Suite 100, San Mateo, California 94403,
Attention: Robert H. Ewald, Chief Executive Officer and (ii) if to any
Underwriter or to you, to you c/o Donaldson, Lufkin & Jenrette Securities

     The respective indemnities, contribution agreements, representations,
warranties and other statements of the Company and the several Underwriters set
forth in or made pursuant to this Agreement shall remain operative and in full
force and effect, and will survive delivery of and payment for the Shares,

                                       22
<PAGE>

regardless of (i) any investigation, or statement as to the results thereof,
made by or on behalf of any Underwriter, the officers or directors of any
Underwriter, any person controlling any Underwriter, the Company, the officers
or directors of the Company or any person controlling the Company, (ii)
acceptance of the Shares and payment for them hereunder and (iii) termination of
this Agreement.

     If for any reason the Shares are not delivered by or on behalf of the
Company as provided herein (other than as a result of any termination of this
Agreement pursuant to Section 9), the Company agrees to reimburse the several
Underwriters for all out-of-pocket expenses (including the fees and
disbursements of counsel) incurred by them. Notwithstanding any termination of
this Agreement, the Company shall be liable for all expenses which it has agreed
to pay pursuant to Section 5(i) hereof.  The Company also agrees to reimburse
the several Underwriters, their directors and officers and any persons
controlling any of the Underwriters for any and all fees and expenses
(including, without limitation, the fees disbursements of counsel) incurred by
them in connection with enforcing their rights hereunder (including, without
limitation, pursuant to Section 7 hereof).

     Except as otherwise provided, this Agreement has been and is made solely
for the benefit of and shall be binding upon the Company, the Underwriters, the
Underwriters' directors and officers, any controlling persons referred to
herein, the Company's directors and the Company's officers who sign the
Registration Statement and their respective successors and assigns, all as and
to the extent provided in this Agreement, and no other person shall acquire or
have any right under or by virtue of this Agreement.  The term "successors and
assigns" shall not include a purchaser of any of the Shares from any of the
several Underwriters merely because of such purchase.

     This Agreement shall be governed and construed in accordance with the laws
of the State of New York.

     This Agreement may be signed in various counterparts which together shall
constitute one and the same instrument.

be issued, or other securities held in the treasury of the Corporation, whether
issued or sold for cash or other consideration or as a dividend or otherwise.

     In furtherance and not in limitation of the powers conferred by statute,
the Board of Directors is expressly authorized to make, alter, amend or repeal
the Bylaws of the Corporation. Subject to and in accordance with the Delaware
Corporation Law, the Bylaws may be altered or amended or new Bylaws adopted by
the affirmative vote of at least sixty-six and two-thirds percent (66-2/3%) of
the voting power of all of the then-outstanding shares of Voting Stock.

                                  ARTICLE VIII

     A.   Limitation of Liability. To the fullest extent permitted by the
          -----------------------
Delaware Corporation Law as the same exists or as may hereafter be amended, a
director of the Corporation shall not be personally liable to the Corporation or
its stockholders for monetary damages for breach of his or her fiduciary duty as
a director except for liability (i) for any breach of the director's duty of
loyalty to the Corporation or its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the Delaware Corporation Law, as the same exists
or hereafter may be amended, or (iv) for any transaction from which the director
derived

                                      -4-
<PAGE>

an improper personal benefit. If the Delaware Corporation Law is amended after
the date of filing of this Certificate of Incorporation to authorize corporate
action further eliminating or limiting the personal liability of directors, then
the liability of a director of the Corporation, in addition to the limitation on
personal liability provided herein, shall be limited to the fullest extent
permitted by the amended Delaware Corporation Law.

     B.   Indemnification. The Corporation shall indemnify to the fullest extent
          ---------------
permitted by law any person made or threatened to be made a party to an action
or proceeding, whether criminal, civil, administrative, or investigative, by
reason of the fact that such person is or was a director or officer of the
Corporation or any predecessor of the Corporation or serves or served at any
other enterprise as a director, officer, or employee at the request of the
Corporation or any predecessor to the Corporation.

     C.   Effect of Amendment. Neither any amendment nor repeal of this Article
          -------------------
VIII, nor the adoption of any provision of this Certificate of Incorporation
inconsistent with this Article VIII, shall eliminate or reduce the effect of
this Article VIII, in respect of any matter occurring, or any cause of action,
suit, claim or proceeding that, but for this Article VIII, would accrue or
arise, prior to such amendment, repeal or adoption of any inconsistent
provision. Any repeal or modification of this Article VIII by the stockholders
of the Corporation shall be prospective only, and shall not adversely affect any
limitation on the personal liability of a director of the Corporation existing
at the time of such repeal or modification.

                                   ARTICLE IX

     A.   Number and Election of Directors. The number of directors which
          --------------------------------
constitute the whole Board of Directors of the Corporation shall be as specified
in the Bylaws of the 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 and 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 Delaware Corporation Law.

     B.   Classification of Directors. The directors of the Corporation shall be
          ---------------------------
divided into three classes as nearly equal in size as is practicable, hereby
designated Class I, Class II, and Class III. The term of office of the initial
Class I directors shall expire at the first regularly-scheduled annual meeting
of the stockholders following the effective date of this Certificate of
Incorporation (the "Effective Date"), the term of office of the initial Class II
directors shall expire at the second annual meeting of the stockholders
following the Effective Date and the term of office of the initial Class III
directors shall expire at the third annual meeting of the stockholders following
the Effective Date. At each annual meeting of stockholders, commencing with the
first regularly-scheduled annual meeting of stockholders following the Effective
Date, each of the successors elected to replace the directors of a class whose
terms shall have expired at such annual meeting shall be elected

                                      -5-
<PAGE>

to hold office until the third annual meeting next succeeding his or her
election and until his or her respective successor shall have been duly elected
and qualified.

     C.   Change in Number of Directors. If the number of directors is hereafter
          -----------------------------
changed, 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, provided that no decrease in the number of directors
constituting the Board of Directors shall shorten the term of any remaining
incumbent director.

     D.   Removal of Directors. Subject to the provisions of any applicable
          --------------------
Preferred Stock Designation, a director or the entire Board of Directors may be
removed from office by the stockholders of the Corporation only for cause, by
the affirmative vote of the holders of a majority of the voting power of all of
the Voting Stock. Notwithstanding the preceding sentence to the contrary, at any
time when the Corporation has less than five hundred (500) record stockholders,
a director or the entire Board of Directors may be removed from office by the
stockholders of the Corporation for cause or without cause, by the affirmative
vote of the holders of a majority of the voting power of all of the Voting
Stock.

     E.   Vacancies. Subject to the provisions of any applicable Preferred Stock
          ---------
Designation, any vacancies occurring on the Board of Directors for any reason
and newly-created directorships resulting from an increase in the authorized
number of directors may be filled only by vote of a majority of the remaining
members of the Board of Directors, although 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 or newly-created directorship shall hold office until the next
election of the class for which such director shall have been chosen and until
his or her successor shall have been duly elected and qualified.

                                   ARTICLE X

     Elections of directors need not be by written ballot unless the Bylaws of
the Corporation shall so provide.

                                   ARTICLE XI

     A.   Stockholder Action. At any time when the Corporation has five hundred
          ------------------
(500) or more record stockholders, no action shall be taken by the stockholders
of the Corporation except at an annual or special meeting of stockholders called
in accordance with the Bylaws of the Corporation and no action shall be taken by
the stockholders by written consent. Prior to such time, action may be taken by
the stockholders by written consent in accordance with the provisions of Section
228 of the Delaware Corporation Law.

     B.   Special Meetings. Special meetings of the stockholders of the
          ----------------
Corporation may be called, for any purpose or purposes, by (i) the Chairman of
the Board

                                      -6-
<PAGE>

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

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

outside the State of Delaware at such place or places as may be designated from

                                  ARTICLE XIII

     The Corporation is to have perpetual existence.

                                  ARTICLE XIV

     Whenever a compromise or arrangement is proposed between the Corporation
and its creditors or any class of them and/or between the Corporation and its
stockholders or any class of them, any court of equitable jurisdiction within
the State of Delaware may, on the application in a summary way of the
Corporation or of any creditor or stockholder thereof or on the application of
any receiver or receivers appointed for the Corporation under Section 291 of the
Delaware Corporation Law or on the application of trustees in dissolution or of
any receiver or receivers appointed for the Corporation under Section 279 of the
Delaware Corporation Law order a meeting of the creditors or class of creditors,
and/or of the stockholders or class of stockholders of the Corporation, as the
case may be, to be summoned in such manner as the said court directs. If a
majority in number representing three-fourths in value of the creditors or class
of creditors, and/or of the stockholders or class of stockholders of the
Corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of the Corporation as a consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of the Corporation as the case may be,
and also on the Corporation.

question is one upon which, by express provision of the laws of the State of
Delaware or of the Certificate of Incorporation or these Bylaws, a different
vote is required, in which case such express provision shall govern and control
the decision of the question.

     If a quorum be initially present, the stockholders may continue to transact

unless the Board of Directors fixes a new record date for the adjourned meeting,
but the Board of Directors shall fix a new record date if the meeting is
adjourned for more than thirty (30) days from the date set for the original

a written proxy signed by the person and filed with the Secretary of the
Corporation, but no such proxy shall be voted or acted upon after three (3)
years from its date, unless the proxy provides for a longer period.  A proxy
shall be deemed signed if the stockholder's name is placed on the proxy (whether
by manual signature, typewriting, telegraphic transmission, telefacsimile or
otherwise) by the stockholder or the stockholder's attorney-in-fact.  The

     3.1  POWERS
          ------

     Subject to the provisions of the General Corporation Law of Delaware and to
any limitations in the Certificate of Incorporation or these Bylaws relating to
action required to be approved by the stockholders or by the outstanding shares,
the business and affairs of the Corporation shall be managed and all corporate
powers shall be exercised by or under the direction of the Board of Directors.

     3.2  NUMBER OF DIRECTORS
          -------------------

     The Board of Directors shall initially consist of eight (8) members.  The
number of directors may be increased or decreased by a resolution duly adopted
by the Board of Directors or by the stockholders, or by a duly adopted amendment
to the Certificate of Incorporation.

     3.3  ELECTION AND TERM OF OFFICE OF DIRECTORS; CLASSES
          -------------------------------------------------

     Except as provided in Section 3.4 of these Bylaws, directors shall hold
office until the expiration of the term for which elected and until a successor
has been elected and qualified; except that if any such election shall not be so
held, such election shall take place at a stockholder's meeting

                                      -5-
<PAGE>

called and held in accordance with the General Corporation Law of Delaware.
Election of directors need not be by written ballot.

     The directors of the Corporation shall be divided into three classes as
nearly equal in size as is practicable, hereby designated Class I, Class II and
Class III.  The term of office of the initial Class I directors shall expire at
the first regularly-scheduled annual meeting of the stockholders following the
effective date of these Bylaws (the "Effective Date"), the term of office of the
initial Class II directors shall expire at the second annual meeting of the
stockholders following the Effective Date and the term of office of the initial
Class III directors shall expire at the third annual meeting of the stockholders
following the Effective Date.  For the purposes thereof, the initial Class I,
Class II, and Class III directors shall be those directors so designated by the
Board of Directors in written action taken in August 1996.  At each annual
meeting of stockholders, commencing with the first regularly-scheduled annual
meeting of stockholders following the Effective Date, each of the successors
elected to replace the directors of a class whose term shall have expired at
such annual meeting shall be elected to hold office until the third annual
meeting next succeeding his or her election and until his or her respective
successor shall have been duly elected and qualified.  If the number of
directors is hereafter changed, 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, provided that no decrease in the
number of directors constituting the Board of Directors shall shorten the term
of any remaining incumbent director.

     3.4  RESIGNATION AND VACANCIES
          -------------------------

     Any director may resign effective upon giving written notice to the
Chairman of the Board, the President, the Secretary or the Board of Directors,
unless the notice specifies a later time for that resignation to become
effective.

     If the resignation of a director is effective at a future time, the Board
of Directors may elect a successor to take office when the resignation becomes
effective.  Each director so elected shall hold office until the expiration of
the term of office of the director whom he or she has replaced and until a
successor has been elected and qualified.

     Unless otherwise provided in the Certificate of Incorporation or these
Bylaws, vacancies occurring on the Board of Directors for any reason and newly
created directorships resulting from an increase in the authorized number of
directors may be filled only by vote of a majority of the remaining members of
the Board of Directors, although 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
or newly created directorship shall hold office until the next election of the
class for which such director shall have been chosen and until his or her
successor shall have been duly elected and qualified.

     If at any time, by reason of death or resignation or other cause, the
Corporation should have no directors in office, then the provisions of Section
223 of the General Corporation Law of Delaware shall apply to filling such
vacancies.

                                      -6-
<PAGE>

     If, at the time of filling any vacancy or any newly created directorship,
the directors then in office constitute less than a majority of the whole Board
(as constituted immediately prior to any such increase), then the provisions of
Section 223 of the General Corporation Law of Delaware shall apply to filling
such vacancy or newly created directorship.

     3.5  REMOVAL OF DIRECTORS
          --------------------

     As provided in the Certificate of Incorporation, a director or the entire
Board of Directors may be removed from office by the stockholders of the
Corporation only for cause, by a vote of the holders of a majority of the shares
then entitled to vote at an election of directors.  Notwithstanding the
preceding sentence to the contrary, at any time when the Corporation has less
than five hundred (500) record stockholders, a director or the entire Board of
Directors may be removed from office by the stockholders of the Corporation for
cause or without cause, by a vote of the holders of a majority of the shares
then entitled to vote at an election of directors.

Delaware that has been designated in the notice of the meeting or, if not stated

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

business notwithstanding the withdrawal of directors, if any action taken is
approved by at least a majority of the quorum for that meeting.

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

     Notice of a meeting need not be given to any director (i) who signs a
waiver of notice, whether before or after the meeting, or (ii) who attends the

be taken without a meeting, provided that all members of the Board consent in

     3.18 NOMINATION OF DIRECTORS; STOCKHOLDERS' BUSINESS AT ANNUAL MEETINGS
          ------------------------------------------------------------------

     Subject to the rights of holders of any class or series of stock of the
Corporation having a preference over the common stock of the Corporation as to
dividends or upon liquidation, nominations for the election of directors may be
made by the Board of Directors or any nominating committee appointed by the
Board of Directors.  However, a stockholder generally entitled to vote in the
election of directors may nominate one or more persons for election as directors
at a meeting only if written notice of such stockholder's intent to make such
nomination or nominations has been given, either by personal delivery or by
United States mail, postage prepaid, to the Secretary of the Corporation not
later than (i) with respect to an election to be held at an annual meeting of
stockholders, 60 days in advance of the first anniversary of the preceding
year's annual meeting and (ii) with respect to an election to be held at the
first annual meeting of stockholders or a special meeting of stockholders for
the election of directors, the close of business on the tenth day following the
date on which notice of such meeting is first given to stockholders.  Each such
notice shall set forth the following information: (a) the name and address of
the stockholder who intends to make the nomination and of the person or persons
to be nominated, (b) a representation that the stockholder is a holder of record
of stock of the Corporation entitled to vote at such meeting and intends to
appear in person or by proxy at the meeting to nominate the person or persons
specified in the notice, (c) a description of all arrangements or understandings
between the stockholder, each nominee or any other person or persons (naming
such person or persons) pursuant to which the nomination or nominations are to
be made by the stockholder, (d) such other information regarding each nominee
proposed by such stockholder as would be required to be included pursuant to
Regulation 14A under the Securities Exchange Act of 1934, as amended (the "1934
Act"), had the nominee been nominated, or intended to be nominated, by the Board
of Directors of the Corporation, and (e) the consent of each nominee to serve as
a director of the Corporation if so elected.  At the request of the Board of
Directors any person nominated by the Board of Directors for election as a
director shall furnish to the Secretary of the Corporation that information
required to be set forth in a stockholder's notice of nomination which pertains
to the nominee.  No person shall be eligible for election as a director of the
Corporation unless nominated in accordance with the procedures set forth herein.
A majority of the Board of Directors may reject any nomination by a stockholder
not timely made or otherwise not in accordance with the terms of this Section
3.18.  If a majority of the Board of Directors reasonably determines that the
information provided in a stockholder's notice does not satisfy the
informational requirements of this Section 3.18 in any material respect, the
Secretary of the Corporation shall promptly notify such stockholder of the
deficiency in writing.  The stockholder shall have an opportunity to cure the
deficiency by providing additional information to the Secretary within such
period of time, not to exceed ten (10) days from the date such deficiency notice
is given to the stockholder, as a majority of the Board of Directors shall
reasonably determine.  If the deficiency is not cured within such period, or if
a majority of the Board of Directors reasonably determines that the additional
information provide by the stockholder, together with the information previously
provided, does not satisfy the requirements of this Section 3.18 in any material
respect, then a majority of the Board of Directors may reject such stockholder's
nomination.  The Secretary of the Corporation shall notify a stockholder in
writing whether the stockholder's nomination has been made in accordance with
the time and information requirements of this Section 3.18.

                                      -10-
<PAGE>

     At an annual meeting of the stockholders, only such business shall be
conducted as shall have been brought before the meeting (i) by or at the
direction of the chairman of the meeting or (ii) by any stockholder of the
Corporation who complied with the notice procedures set forth in this Section
3.18.  For business to be properly brought before an annual meeting by a
stockholder, the stockholder must have given timely notice thereof in writing to
the Secretary of the Corporation.  To be timely, a stockholder's notice must be
delivered to or mailed and received at the principal executive office of the
Corporation not less than 60 days prior to the meeting, provided, however, that
in the event that less than 70 days notice or prior public disclosure of the
date of the meeting is given or made to stockholders, notice by the stockholder
to be timely must be received not later than the close of business on the tenth
day following the earlier of the day on which such notice of the date of the
annual meeting was mailed or such public disclosure was made.  A stockholder's
notice to the Secretary shall set forth as to each matter the stockholder
proposes to bring before the annual meeting the following information: (a) a
brief description of the business desired to be brought before the annual
meeting and the reasons for conducting such business at the annual meeting, (b)
the name and address, as they appear on the Corporation's books, of the
stockholder proposing such business, (c) the class and number of shares of the
Corporation which are beneficially owned by the stockholder and (d) any material
direct or indirect interest, financial or otherwise, of the stockholder or its
affiliates or associates in such business.  The Board of Directors may reject
any stockholder proposal not timely made in accordance with this Section 3.18.
Additionally, the Board of Directors may reject any stockholder proposal
pursuant to the 1934 Act or any rules or regulations thereto or pursuant to the
rules of any national or regional stock exchange which governs the trading of
shares of the Corporation.  If the Board of Directors determines that the
purpose or information provided in a stockholder's notice does not satisfy the
requirements hereof, the Secretary of the Corporation shall promptly notify such
stockholder of the deficiency in the notice.  The stockholder shall then have an
opportunity to cure the deficiency by providing additional information to the
Secretary within such period of time, not to exceed ten (10) days from the date
such deficiency notice is given to the stockholder, as the Board of Directors
shall determine.  If the deficiency is not cured within such period, or if the
Board of Directors determines that the additional information provided by the
stockholder, together with the information previously provided, does not satisfy
the requirements of this Section 3.18, then the Board of Directors may reject
such stockholder's proposal.  The Secretary of the Corporation shall notify a
stockholder in writing whether the stockholder's proposal has been made in
accordance with the time and information requirements hereof.

     This provision shall not prevent the consideration and approval or
disapproval at an annual meeting of reports of officers, directors and
committees of the Board of Directors, but in connection therewith no new
business shall be acted upon at any such meeting unless stated, filed and
received as herein provided.  Notwithstanding anything in these Bylaws to the
contrary, no business shall be conducted at an annual meeting except in
accordance with procedures set forth in this Section 3.18.

     3.19 ORGANIZATION

of the Corporation shall act as secretary of all meetings of the Board of
Directors, but in the absence of the Secretary at any meeting of the Board of
Directors, the chairman of the meeting may appoint any person to act as
secretary of the meeting. The Chairman of the Board, if such an officer be

Any committee, to the extent provided in the resolution of the Board, shall have
and may exercise all the powers and authority of the Board, but no such
committee shall have the power or authority to (i) approve or adopt, or
recommend to the stockholders, any action or matter expressly required by the

of any other rights which such person may have or hereafter acquire under any
statute, provision of the Certificate of Incorporation, these Bylaws, agreement,
vote of the stockholders or disinterested directors or otherwise.

     8.1  RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING
          -----------------------------------------------------

     For purposes of determining the stockholders entitled to receive payment of
any dividend or other distribution or allotment of any rights or the
stockholders entitled to exercise any rights in respect of any change,
conversion or exchange of stock, or for the purpose of any other lawful action,
the Board of Directors may fix in advance a record date, which shall not precede
the date upon which the resolution fixing the record date is adopted and which
shall not be more than sixty (60) days before any such action.  In that case,
only stockholders of record at the close of business on the date so fixed are
entitled to receive the dividend, distribution or allotment of rights, or to
exercise such rights, as the case may be, notwithstanding any transfer of any
shares on the books of the Corporation after the record date so fixed, except as
otherwise provided by law.

     If the Board of Directors does not so fix a record date, then the record
date for determining stockholders for any such purpose shall be at the close of

each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of the certificate that the Corporation shall
issue to represent such class or series of stock; provided, however, that,
except as otherwise provided in Section 201 of the General Corporation Law of
Delaware (relating to transfers of stock, stock certificates and uncertificated
stock), in lieu of the foregoing requirements there may be set forth on the face
or back of the certificate that the Corporation shall issue to represent such
class or series of stock a statement that the Corporation will furnish without

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

     Except as provided in this Section 8.5, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the Corporation and cancelled at the same time.  The Board of
Directors may, in case any share certificate or certificate for any other
security is lost, stolen or destroyed, authorize the issuance of replacement
certificates on such terms and conditions as the Board may require; the Board
may require indemnification of the Corporation secured by a bond or other
adequate security sufficient to protect the Corporation against any claim that
may be made against it, including any expense or liability, on account of the
alleged loss, theft or destruction of the certificate or the issuance of the
replacement certificate.

     8.6  TRANSFER AGENTS AND REGISTRARS
          ------------------------------

     The Board of Directors may appoint one or more transfer agents or transfer
clerks, and one or more registrars, each of which shall be appointed at such

other claim to or interest in such share or shares on the part of any other
person, whether or not it shall have express or other notice thereof, except as
otherwise provided by the General Corporation Law of Delaware.

aside out of any funds of the Corporation available for dividends such sum or
sums as the Board of Directors from time to time, in their absolute discretion,
think proper as a reserve or reserves to meet contingencies, or for equalizing
dividends, or for repairing or maintaining any property of the Corporation, or
for such other purpose as the Board of Directors shall think conducive to the

     The original or other Bylaws of the Corporation may be adopted, amended or

conferred upon the directors shall not

                                      -21-
<PAGE>

divest the stockholders of the power, nor limit their power to adopt, amend or

certifies:

     That, pursuant to the authority contained in Article IV of the Certificate
of Incorporation of the Corporation (the "Certificate of Incorporation") and in
                                          ----------------------------
accordance with the provisions of Section 151 of the General Corporation Law of
the State of Delaware (the "Delaware Act"), the Board of Directors of the
                            ------------
Corporation has duly adopted, by unanimous written consent dated August 28,
1997, the following resolution creating and providing for the establishment and
issuance of a series of shares of serial preferred stock as hereinafter
described, providing for the designations, preferences, limitations and
relative, voting, conversion and other rights thereof and the qualifications,
limitations, or restrictions thereof, in addition to those set forth in the
Certificate of Incorporation, all in accordance with the provisions of Section
151 of the Delaware Act:

     RESOLVED, that pursuant to Article IV of the Certificate of Incorporation,
which authorizes the issuance 105,000,000 shares of stock, consisting of
100,000,000 shares of common stock, $.001 par value (the "Common Stock"), and
                                                          ------------
5,000,000 shares of preferred stock, $.001 par value (the "Preferred Stock"),
                                                           ---------------
the Corporation hereby provides for the issuance of a series of 2,500,000 shares
of Preferred Stock, to be designated as Series A Preferred Stock (the "Series A
                                                                       --------
Preferred Stock"), and hereby approves the designation, issuance, and sale by
- ---------------
the Corporation of 2,500,000 shares of the Series A Preferred Stock and hereby
provides for the following designations, preferences, limitations and relative,
voting, conversion, and other rights thereof and the qualifications,
limitations, or restrictions thereof:

     1.  Designation of Series A.  There shall be a series of Preferred Stock
         -----------------------
designated as "Series A Preferred Stock", par value $.001 per share, consisting
of 2,500,000 shares.  Each share of Series A Preferred Stock shall be referred
to herein as a "Series A Preferred Share" or "Share."

     2.  Voting.  The holder of each share of Series A Preferred Stock shall
         ------
have the right to one vote for each share of Common Stock into which such Series
A Preferred Stock could then be converted as provided hereinbelow, and with
respect to such vote, such holder shall have full voting rights and powers equal
to the voting rights and powers of the holders of Common Stock, and shall be
entitled to notice of any stockholders' meeting in accordance with the bylaws of
the Corporation, and shall be entitled to vote, together with holders of Common
Stock, with

                                 Page 1 of 12
<PAGE>

respect to any question upon which holders of Common Stock have the right to
vote. Fractional votes shall not, however, be permitted and any fractional
voting rights available on an as-converted basis (after aggregating all shares
into which shares of Series A Preferred Stock held by each holder could be
converted) shall be rounded to the nearest whole number (with one-half being
rounded upward).

     3.  Protective Provisions.  Subject to the rights of other series of
         ---------------------
Preferred Stock which may from time to time come into existence, so long as any
shares of Series A Preferred Stock are outstanding, the Corporation shall not
without first obtaining the approval (by vote or written consent, as provided by
law) which such approval shall not be unreasonably withheld, conditioned, or
delayed of the holders of at least fifty percent (50%) of the then outstanding
shares of Series A Preferred Stock, voting together as a class:

               (a) sell, convey, or otherwise dispose of or encumber all or
substantially all of its property or business or merge into or consolidate with
any other corporation (other than a wholly-owned subsidiary corporation) or
affect any other transaction or series of related transactions in which more
than fifty percent (50%) of the voting power of the Corporation is disposed of,
provided that this Section 3(a) shall not apply to a merger effected exclusively
- --------
for the purpose of changing the domicile of the Corporation;

               (b) alter or change the rights, preferences, or privileges of the
shares of Series A Preferred Stock in any manner or exchange, reclassify, or
cancel all or part of the Series A Preferred Stock;

               (c) increase or decrease (other than by redemption or conversion)
the total number of authorized shares of Common Stock, Series A Preferred Stock,
or any other series of Preferred Stock;

               (d) authorize or issue, or obligate itself to issue, any other
equity security, including any other security convertible into or exercisable
for any equity security having a preference over, or being on a parity with, the
Series A Preferred Stock with respect to redemption, voting, dividends or upon
liquidation;

               (e) perform any act or omission that would result in taxation of
the holders of the Series A Preferred Stock under Section 305 of the Internal
Revenue Code of 1986, as amended;

               (f) declare or pay any dividend or cancel or modify any dividends
on the Series A Preferred Stock which have been declared but not yet paid;

               (g) change the authorized number of directors of the Corporation
from seven members;

               (h) authorize the aggregate number of shares of Common Stock that
are available for issuance under the Corporation's 1996 Stock Option and
Restricted Stock Plan to an amount greater than 2,000,000 shares of Common Stock
except as adjusted for stock splits, stock dividends, consolidations,
recapitalizations, and similar events;

                                 Page 2 of 12
<PAGE>

               (i) authorize the aggregate number of shares of Common Stock that
are available for issuance under the Corporation's 1996 Non-Employee Director
Stock Option Plan to an amount greater than 100,000 shares of Common Stock
except as adjusted for stock splits, stock dividends, consolidations,
recapitalizations, and similar events; or

               (j) authorize or issue any capital stock or rights therefore to
third parties without the prior approval of the Board of Directors of the
Corporation or a duly appointed committee thereof.

     4.  Dividends.  Subject to the rights of other series of Preferred Stock
         ---------
which may from time to time come into existence, the holders of shares of Series
A Preferred Stock shall be entitled to receive dividends, out of any assets
legally available therefor prior and in preference to any declaration or payment
of any dividend (payable other than in Common Stock or other securities and
rights convertible into or entitling the holder thereof to receive, directly or
indirectly, additional shares of Common Stock) on the Common Stock, at the rate
of $0.192 per share per annum on each outstanding share of Series A Preferred
Stock, payable quarterly when, as, and only if declared by the Board of
Directors.  Such dividends shall not be cumulative.

     5.  Liquidation.
         -----------

         (a) Preference.  In the event of any liquidation, dissolution or
             ----------
winding up of the Corporation, either voluntary or involuntary, subject to the
rights of other series of Preferred Stock that may from time to time come into
existence, the holders of the Series A Preferred Stock shall be entitled to
receive, prior and in preference to any distribution of any of the assets of the
Corporation to the holders of Common Stock by reason of their ownership thereof,
an amount per share equal to $2.40 per share for each share of Series A
Preferred Stock then held by them, plus any declared but unpaid dividends.  If,
upon the occurrence of such event, the assets and funds thus distributed among
the holders of the Series A Preferred Stock shall be insufficient to permit the
payment to such holders of the full aforesaid preferential amount, then, subject
to the rights of other series of Preferred Stock that may from time to time come
into existence, the entire assets and funds of the Corporation legally available
for distribution shall be distributed ratably among the holders of the Series A
Preferred Stock in proportion to the preferential amount each such holder is
otherwise entitled to receive.

         (b) Remaining Assets.  Upon the completion of the distribution
             ----------------
required by Section 5(a) above and any other distribution that may be required
with respect to other series of Preferred Stock that may from time to time come
into existence, the remaining assets of the Corporation available for
distribution to stockholders shall be distributed among the holders of the
Series A Preferred Stock and the Common Stock pro rata based on the number of
shares of Common Stock held by each (assuming conversion of all such Series A
Preferred Stock).

         (c) Deemed Liquidation.  For purposes of this Section 5, a
             ------------------
liquidation, dissolution or winding up of the Corporation shall be deemed to be
occasioned by, or to include, (i) the acquisition of the Corporation by another
entity by means of any transaction or series of related transactions (including,
without limitation, any reorganization, merger or consolidation,

                                 Page 3 of 12
<PAGE>

but excluding any merger effected exclusively for the purpose of changing the
domicile of the Corporation); or (ii) a sale of all or substantially all of the
assets of the Corporation, unless the Corporation's stockholders of record as
                           ------
constituted immediately prior to such acquisition or sale will, immediately
after such acquisition or sale (by virtue of securities issued as consideration
for the Corporation's acquisition or sale or otherwise) hold at least 50% of the
voting power of the surviving or acquiring entity in approximately the same
relative percentages after such acquisition or sale as before such acquisition
or sale.

         (d) Market Value.  In any of the events specified in (c) above, if the
             ------------
consideration received by the Corporation is other than cash, its value will be
deemed its fair market value.  Any securities shall be valued as follows:

             (i)    Securities not subject to investment letter or other
similar restrictions on free marketability:

                    (A) If traded on a securities exchange or the Nasdaq
National Market System, the value shall be deemed to be the average of the
closing prices of the securities on such exchange over the thirty-day period
ending three (3) days prior to the closing;

                    (B) If actively traded over-the-counter, the value shall be
deemed to be the average of the closing bid or sale prices (whichever is
applicable) over the thirty-day period ending three (3) days prior to the
closing; and

                    (C) If there is no active public market, the value shall be
the fair market value thereof, as mutually determined by the Corporation and the
holders of at least fifty percent (50%) of the voting power of all then
outstanding shares of Preferred Stock.

             (ii)   The method of valuation of securities subject to investment
letter or other restrictions on free marketability (other than restrictions
arising solely by virtue of a stockholder's status as an affiliate or former
affiliate) shall be to make an appropriate discount from the market value
determined as above in (i)(A),(B) or (C) to reflect the approximate fair market
value thereof, as mutually determined by the Corporation and the holders of at
least fifty percent (50%) of the voting power of all then outstanding shares of
Preferred Stock.

             (iii)  In the event the requirements of Section 5(c) are not
complied with, the Corporation shall forthwith either:

                    (A) cause such closing to be postponed until such time as
the requirements of this Section 5 have been complied with; or

                    (B) cancel such transaction, in which event the rights,
preferences and privileges of the holders of the Series A Preferred Stock shall
revert to and be the same as such rights, preferences and privileges existing
immediately prior to the date of the first notice referred to in Section
5(c)(iv) hereof.

                                 Page 4 of 12
<PAGE>

             (iv)   The Corporation shall give each holder of record of Series A
Preferred Stock written notice of such impending transaction not later than
twenty (20) days prior to the stockholder's meeting called to approve such
transaction, or twenty (20) days prior to the closing of such transaction,
whichever is earlier, and shall also notify such holders in writing of the final
approval of such transaction.  The first of such notices shall describe the
material terms and conditions of the impending transaction and the provisions of
this Section 5, and the Corporation shall thereafter give such holders prompt
notice of any material changes.  The transaction shall in no event take place
sooner than twenty (20) days after the corporation has given the first notice
provided for herein or sooner than ten (10) days after the Corporation has given
notice of any material changes provided for herein; provided, however, that such
periods may be shortened upon the written consent of the holders of Preferred
Stock that are entitled to such notice rights or similar notice rights and that
represent at least fifty percent (50%) of the voting power of all then
outstanding shares of such Preferred Stock.

     6.  Conversion.  The holders of the Series A Preferred Stock shall have
         ----------
conversion rights as follows (the "Conversion Rights"):
                                   -----------------

         (a) Right to Convert.  Subject to Section 6(c), each share of Series A
             ----------------
Preferred Stock shall be convertible, at the option of the holder thereof, at
any time after the date of issuance of such share, at the principal corporate
office of the Corporation or any transfer agent for such stock, into such number
of fully paid and nonassessable shares of Common Stock as is determined by
dividing $2.40 by the Conversion Price applicable to such share in effect on the
date the certificate is surrendered for conversion.  The initial Conversion
Price per share of Series A Preferred Stock shall be $2.40 (the "Conversion
                                                                 ----------
Price").  Such initial Conversion Price shall be subject to adjustment as set
- -----
forth in Section 6(d).

         (b) Automatic Conversion.  Each share of Series A Preferred Stock
             --------------------
shall automatically be converted into shares of Common Stock at the Conversion
Price at the time in effect for such share immediately upon the earlier of (i)
the Corporation's sale of its Common Stock pursuant to a firm commitment
underwritten public offering pursuant to an effective registration statement
filed pursuant to the Securities Act of 1933, as amended, the public offering
price of which is not less than $12.00 per share (adjusted to reflect subsequent
stock dividends, stock splits, or recapitalizations) and which results in
aggregate gross cash proceeds to the Corporation of more than $15,000,000, or
(ii) the date specified by written consent or agreement of the holders of at
least fifty percent (50%) of the then outstanding shares of Series A Preferred
Stock.

         (c) Mechanics of Conversion.  Before any holder of Series A Preferred
             -----------------------
Stock shall be entitled to convert the same into shares of Common Stock pursuant
to Section 6(a), he shall give written notice at least ten (10) days prior to
the Corporation at its principal corporate office, of the election to convert
the same and shall state therein the name or names in which the certificate or
certificates for shares of Common Stock are to be issued.  He shall surrender
the certificate or certificates therefor, duly endorsed, at the office of the
Corporation or of any transfer agent for the Series A Preferred Stock.  The
Corporation shall, as soon as practicable thereafter, issue and deliver at such
office to such holder of Series A Preferred Stock, or to the nominee or nominees
of such holder, a certificate or certificates for the number of shares of

                                 Page 5 of 12
<PAGE>

Common Stock to which such holder shall be entitled as aforesaid. Such
conversion shall be deemed to have been made immediately prior to the close of
business on the date of such surrender of the shares of Series A Preferred Stock
to be converted, and the person or persons entitled to receive the shares of
Common Stock issuable upon such conversion shall be treated for all purposes as
the record holder or holders of such shares of Common Stock as of such date. If
the conversion is in connection with an underwritten offering of securities
registered pursuant to the Securities Act of 1933, the conversion may, at the
option of any holder tendering Series A Preferred Stock for conversion, be
conditioned upon the closing with the underwriters of the sale of securities
pursuant to such offering, in which event the person(s) entitled to receive
Common Stock upon conversion of such Preferred Stock shall not be deemed to have
converted such Preferred Stock until immediately prior to the closing of such
sale of securities.

         (d) Conversion Price Adjustments.  The Conversion Price of the Series
             ----------------------------
A Preferred Stock shall be subject to adjustment from time to time as follows:

             (i)    (A) If the Corporation shall issue, after the date upon
which any shares of Series A Preferred Stock were first issued (the "Purchase
                                                                     --------
Date"), any Additional Stock (as defined below) without consideration or for a
- ----
consideration per share less than the Conversion Price for the Series A
Preferred Stock in effect immediately prior to the issuance of such Additional
Stock, the Conversion Price for the Series A Preferred Stock in effect
immediately prior to such issuance shall automatically (except as otherwise
provided in this clause (i)) be adjusted to a price equal to the price paid per
share for such Additional Stock.

                    (B) No adjustment of the Conversion Price for the Series A
Preferred Stock shall be made in an amount less than one cent per share,
provided that any adjustments which are not required to be made by reason of
this sentence shall be carried forward and shall be either taken into account in
any subsequent adjustment made prior to three years from the date of the event
giving rise to the adjustment being carried forward, or shall be made at the end
of three years from the date of the event giving rise to the adjustment being
carried forward. Except to the limited extent provided for in Sections
6(d)(i)(E)(3) and 6(d)(i)(E)(4), no adjustment of such Conversion Price pursuant
to this Section 6(d)(i) shall have the effect of increasing the Conversion Price
above the Conversion Price in effect immediately prior to such adjustment.

                    (C) In the case of the issuance of Common Stock for cash,
the consideration shall be deemed to be the amount of cash paid therefor before
deducting any reasonable discounts, commissions or other expenses allowed, paid
or incurred by the Corporation for any underwriting or otherwise in connection
with the issuance and sale thereof.

                    (D) In the case of the issuance of the Common Stock for a
consideration in whole or in part other than cash, the consideration other than
cash shall be deemed to be the fair value thereof as reasonably determined by
the Board of Directors or any committee thereof irrespective of any accounting
treatment.

                    (E) In the case of the issuance (whether before, on or after
the applicable Purchase Date) of options to purchase or rights to subscribe for
Common Stock,

                                 Page 6 of 12
<PAGE>

securities by their terms convertible into or exchangeable for Common Stock or
options to purchase or rights to subscribe for such convertible or exchangeable
securities, the following provisions shall apply for all purposes of this
Section 6(d)(i) and Section 6(d)(ii):

                    (1) The aggregate maximum number of shares of Common Stock
deliverable upon exercise (assuming the satisfaction of any conditions to
exercisability, including without limitation, the passage of time, but without
taking into account potential antidilution adjustments) of such options to
purchase or rights to subscribe for Common Stock shall be deemed to have been
issued at the time such options or rights were issued and for a consideration
equal to the consideration (determined in the manner provided in Sections
6(d)(i)(C) and 6(d)(i)(D)), if any, received by the Corporation upon the
issuance of such options or rights plus the minimum exercise price provided in
such options or rights (without taking into account potential antidilution
adjustments) for the Common Stock covered thereby.

                    (2) The aggregate maximum number of shares of Common Stock
deliverable upon conversion of or in exchange (assuming the satisfaction of any
conditions to convertibility or exchangeability, including, without limitation,
the passage of time, but without taking into account potential antidilution
adjustments) for any such convertible or exchangeable securities or upon the
exercise of options to purchase or rights to subscribe for such convertible or
exchangeable securities and subsequent conversion or exchange thereof shall be
deemed to have been issued at the time such securities were issued or such
options or rights were issued and for a consideration equal to the
consideration, if any, received by the Corporation for any such securities and
related options or rights (excluding any cash received on account of accrued
interest or accrued dividends), plus the minimum additional consideration, if
any, to be received by the Corporation (without taking into account potential
antidilution adjustments) upon the conversion or exchange of such securities or
the exercise of any related options or rights (the consideration in each case to
be determined in the manner provided in Sections 6(d)(i)(C) and 6(d)(i)(D)).

                    (3) In the event of any change in the number of shares of
Common Stock deliverable or in the consideration payable to the Corporation upon
exercise of such options or rights or upon conversion of or in exchange for such
convertible or exchangeable securities, including, but not limited to, a change
resulting from the antidilution provisions thereof, the Conversion Price of the
Series A Preferred Stock, to the extent in any way affected by or computed using
such options, rights or securities, shall be recomputed to reflect such change,
but no further adjustment shall be made for the actual issuance of Common Stock
or any payment of such consideration upon the exercise of any such options or
rights or the conversion or exchange of such securities.

                    (4) Upon the expiration or cancellation of any such options
or rights, the termination of any such rights to convert or exchange or the
expiration of any options or rights related to such convertible or exchangeable
securities, the Conversion Price of the Series A Preferred Stock, to the extent
in any way affected by or computed using such options, rights or securities or
options or rights related to such securities, shall be recomputed to reflect the
issuance of only the number of shares of Common Stock (and convertible or
exchangeable securities which remain in effect) actually issued upon the
exercise of such options

                                 Page 7 of 12
<PAGE>

or rights, upon the conversion or exchange of such securities or upon the
exercise of the options or rights related to such securities

                    (5) The number of shares of Common Stock deemed issued and
the consideration deemed paid therefor pursuant to Sections 6(d)(i)(E)(1) and
6(d)(i)(E)(2) shall be appropriately adjusted to reflect any change, termination
or expiration of the type described in either Section 6(d)(i)(E)(3) or
6(d)(i)(E)(4).

               (ii) "Additional Stock" shall mean any shares of Common Stock
                     ----------------
issued (or deemed to have been issued pursuant to Section 6(d)(i)(E) by the
Corporation after the Purchase Date) but specifically excluding:

               (A) Common Stock issued pursuant to a transaction described
in Section 6(d)(iii) hereof,

               (B) Shares of Common Stock issuable or issued to employees,
consultants, or directors of the Corporation, directly or pursuant to a stock
option plan or restricted stock plan, all as approved by the Board of Directors
of the Corporation,

               (C) Capital stock, or options or warrants to purchase capital
stock, issued to financial institutions or lessors in connection with commercial
credit arrangements, equipment financings or similar transactions, or to vendors
or customers in connection with commercial arrangements, as approved by the
Board of Directors of the Corporation,

               (D) Capital stock or warrants or options to purchase capital
stock issued in connection with bona fide acquisitions, mergers or similar
transactions, the terms of which are approved by the Board of Directors of the
Corporation,

               (E) Shares of Common Stock issued or issuable upon conversion of
the Series A Preferred Stock,

               (F) Shares of Common Stock issued or issuable in a public
offering prior to or in connection with which all outstanding shares of Series A
Preferred stock will be converted to Common Stock, and

               (G) Capital stock, or options or warrants to purchase capital
stock, issued in connection with the licensing or acquisition of intellectual
property or technology rights from third parties, the terms of which are
approved by the Board of Directors of the Corporation.

         (iii) In the event the Corporation should at any time or from time to
time after the Purchase Date fix a record date for the effectuation of a split
or subdivision of the outstanding shares of Common Stock or the determination of
holders of Common Stock entitled to receive a dividend or other distribution
payable in additional shares of Common Stock or other securities or rights
convertible into, or entitling the holder thereof to receive directly or
indirectly, additional shares of Common Stock (hereinafter referred to as
"Common Stock Equivalents") without payment of any consideration by such holder
 ------------------------
for the additional shares of

                                 Page 8 of 12
<PAGE>

Common Stock or the Common Stock Equivalents (including the additional shares of
Common Stock issuable upon conversion or exercise thereof), then, as of such
record date (or the date of such dividend distribution, split or subdivision if
no record date is fixed), the Conversion Price of the Series A Preferred Stock
shall be appropriately decreased so that the number of shares of Common Stock
issuable upon conversion of each share of Series A Preferred Stock shall be
increased in proportion to such increase of the aggregate of shares of Common
Stock outstanding and those issuable with respect to such Common Stock
Equivalents with the number of shares issuable with respect to Common Stock
Equivalents determined from time to time in the manner provided for deemed
issuances in Section 6(d)(i)(E).

              (iv)  If the number of shares of Common Stock outstanding at any
time after the Purchase Date is decreased by a combination of the outstanding
shares of Common Stock, then, following the record date of such combination, the
Conversion Price for the Series A Preferred Stock shall be appropriately
increased so that the number of shares of Common Stock issuable upon conversion
of each share of such series shall be decreased in proportion to such decrease
in outstanding shares.

          (e) Other Distributions.  In the event the Corporation shall declare a
              -------------------
distribution payable in securities of other persons, evidences of indebtedness
issued by the Corporation or other persons, assets (excluding cash dividends) or
options or rights not referred to in Section 6(d)(iii), then, in each such case
for the purpose of this Section 6(e), the holders of Series A Preferred Stock
shall be entitled to a proportionate share of any such distribution as though
they were the holders of the number of shares of Common Stock of the Corporation
into which their shares of Series A Preferred Stock are convertible as of the
record date fixed for the determination of the holders of Common Stock of the
Corporation entitled to receive such distribution.

          (f) Recapitalizations. If at any time or from time to time there shall
              -----------------
be a recapitalization of the Common Stock (other than a subdivision, combination
or merger or sale of assets transaction provided for elsewhere in this Section 6
or Section 5) provision shall be made so that the holders of the Series A
Preferred Stock shall thereafter be entitled to receive upon conversion of the
Series A Preferred Stock the number of shares of stock or other securities or
property of the Company or otherwise, to which a holder of Common Stock
deliverable upon conversion would have been entitled on such recapitalization.
In any such case, appropriate adjustment shall be made in the application of the
provisions of this Section 6 with respect to the rights of the holders of the
Series A Preferred Stock after the recapitalization to the end that the
provisions of this Section 6 (including adjustment of the Conversion Price then
in effect and the number of shares purchasable upon conversion of the Series A
Preferred Stock) shall be applicable after that event and be as nearly
equivalent as practicable.

          (g) No Impairment.  The Corporation will not, by amendment of its
              -------------
Certificate of Incorporation or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by the
Corporation, but will at all times in good faith assist in the carrying out of
all the provisions of this Section 6 and in the taking of all such action as may
be necessary or

                                 Page 9 of 12
<PAGE>

appropriate in order to protect the Conversion Rights of the holders of Series A
Preferred Stock against impairment.

          (h) No Fractional Shares and Certificate as to Adjustments.
              ------------------------------------------------------

                    (i)    No fractional shares shall be issued upon the
conversion of any share or shares of the Series A Preferred Stock, and the
number of shares of Common Stock to be issued shall be rounded to the nearest
whole share. Whether or not fractional shares are issuable upon such conversion
shall be determined on the basis of the total number of shares of Series A
Preferred Stock the holder is at the time converting into Common Stock and the
number of shares of Common Stock issuable upon such aggregate conversion.

                    (ii)   Upon the occurrence of each adjustment or
readjustment of the Conversion Price of Series A Preferred Stock pursuant to
this Section 6, the Corporation, at its expense, shall promptly compute such
adjustment or readjustment in accordance with the terms hereof and prepare and
furnish to each holder of Series A Preferred Stock a certificate setting forth
such adjustment or readjustment and showing in detail the facts upon which such
adjustment or readjustment is based. The Corporation shall, upon the written
request at any time of any holder of Series A Preferred Stock, furnish or cause
to be furnished to such holder a like certificate setting forth (A) such
adjustment and readjustment, (B) the Conversion Price for the Series A Preferred
Stock at the time in effect, and (C) the number of shares of Common Stock and
the amount, if any, of other property which at the time would be received upon
the conversion of a share of the Series A Preferred Stock.

          (i) Notices of Record Date.  In the event of any taking by the
              ----------------------
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, the Corporation
shall mail to each holder of Series A Preferred Stock, at least 20 days prior to
the date specified therein, a notice specifying the date on which any such
record is to be taken for the purpose of such dividend, distribution or right,
and the amount and character of such dividend, distribution or right.

          (j) Reservation of Stock Issuable Upon Conversion.  The Corporation
              ---------------------------------------------
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Series A Preferred Stock, such number of its shares of Common
Stock as shall from time to time be sufficient to effect the conversion of all
outstanding shares of Series A Preferred Stock; and if at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then outstanding shares of Series A Preferred Stock, in
addition to such other remedies as shall be available to the holder of such
Preferred Stock, the Corporation will take such corporate action as may, in the
opinion of its counsel, be necessary to increase its authorized but unissued
shares of Common Stock to such number of shares as shall be sufficient for such
purposes, including, without limitation, engaging in best efforts to obtain the
requisite stockholder approval of any necessary amendment to this Certificate of
Incorporation.

                                 Page 10 of 12

          (k) Notices.  Any notice required by the provisions of this Section 6
              -------
to be given to the holders of shares of Series A Preferred Stock shall be deemed
given if deposited in the United States mail, postage prepaid, and addressed to
each holder of record at his address appearing on the books of the Corporation.

     7.   Redemption.
          ----------

          (a) Election to Redeem. Subject to the rights of other series of
              ------------------
Preferred Stock which may from time to time come into existence, at any time
after the fourth annual anniversary date of the Purchase Date but not later than
the sixth annual anniversary date of the Purchase Date, the Corporation shall
redeem the Series A Preferred Stock upon receipt by the Corporation (the
"Redemption Date") of a written request from the holders of not less than a
 ---------------
majority of the then outstanding Series A Preferred Stock and receipt
simultaneously therewith of the certificates representing the Series A Preferred
Stock to be redeemed.  The Corporation shall, to the extent it may lawfully do
so, redeem within thirty (30) days of the Redemption Date the Series A Preferred
Stock by paying in cash therefor a sum equal to $2.40 per share of Series A
Preferred Stock (as adjusted for any stock dividends, combinations or splits
with respect to such shares) plus interest on such amount computed at the rate
of 10% compounded annually from the date of issuance plus all declared or
accumulated but unpaid dividends on such shares(the "Redemption Price").
                                                     ----------------

          (b) Mechanics.  Subject to the rights of other series of Preferred
              ---------
Stock which may from time to time come into existence, at least fifteen (15) but
no more than thirty (30) days after the Redemption Date, written notice shall be
mailed by the Corporation, first class postage pre-paid, to each holder of
record (at the close of business on the business day next preceding the day on
which notice is given) of the Series A Preferred Stock to be redeemed, at the
address last shown on the records of the Corporation for such holder, notifying
such holder of the redemption to be effected, specifying the number of shares to
be redeemed from such holder, and the Redemption Price.  The Redemption Price of
such shares shall be payable to the order of the person whose name appears on
such certificate or certificates as the owner thereof and each surrendered
certificate shall be cancelled.  In the event less than all the shares
represented by any such certificate are redeemed, a new certificate shall be
issued representing the unredeemed shares.

          (c) Stockholder Rights.  From and after the Redemption Date, all
              ------------------
rights of the holders of shares of Series A Preferred Stock (except the right to
receive the Redemption Price) shall cease with respect to such shares to be
redeemed, and such shares shall not thereafter be transferred on the books of
the Corporation or be deemed to be outstanding for any purpose whatsoever.
Subject to the rights of other series of Preferred Stock which may from time to
time come into existence, if the funds of the Corporation legally available for
redemption of Series A Preferred Stock on any Redemption Date are insufficient
to redeem the total number of shares of Series A Preferred Stock to be redeemed
on such date, those funds which are legally available will be used to redeem the
maximum possible number of such shares ratably among the holders of such shares
to be redeemed based upon their holdings of Series A Preferred Stock.  The
shares of Series A Preferred Stock not redeemed shall remain outstanding and be
entitled to all the rights and preferences provided herein.  Subject to the
rights of other series of Preferred Stock which may from time to time come into
existence, at any time thereafter when additional funds

                                 Page 11 of 12
<PAGE>

of the Corporation are legally available for the redemption of shares of Series
A Preferred Stock, such funds will immediately be used to redeem the balance of
the shares which the Corporation has become obliged to redeem on any Redemption
Date but which it has not redeemed.

          (d)  Sinking Fund.  No sinking fund shall be established for any
               ------------
redemption of the Series A Preferred Stock.

     8.   Status of Reacquired Series A Preferred Stock.  Series A Preferred
          ---------------------------------------------
Stock issued and reacquired by the Corporation (including by conversion or
redemption) shall have the status of authorized and unissued shares of Preferred
Stock undesignated as to series, subject to later issuance, provided that they
may not be reissued as Series A Preferred Stock.

     9.   Preemptive Rights.  The Series A Preferred Stock is not entitled to
          -----------------
any preemptive or subscription rights in respect of any securities of the
Corporation unless and to the extent provided by written agreement with the
Corporation.

     10.  Severability of Provisions.  Whenever possible, each provision hereof
          --------------------------
shall be interpreted in a manner as to be effective and valid under applicable
law, but if any provision hereof is held to be prohibited by or invalid under
applicable law, such provision shall be ineffective only to the extent of such
prohibition or invalidity, without invalidating or adversely affecting the
remaining provisions hereof.

     IN WITNESS WHEREOF, this Statement of Resolution has been executed by an
officer of the Corporation, this 28th day of August, 1997.

     E-Stamp Corporation, a Delaware corporation (the "Corporation"), hereby
                                                       -----------
certifies:

     That, pursuant to the authority contained in Article IV of the Certificate
of Incorporation of the Corporation (the "Certificate of Incorporation") and in
                                          ----------------------------
accordance with the provisions of Section 151 of the General Corporation Law of
the State of Delaware (the "Delaware Act"), the Board of Directors of the
                            ------------
Corporation has duly adopted, by unanimous written consent dated June 26, 1998,
the following resolution creating and providing for the establishment and
issuance of a series of shares of serial preferred stock as hereinafter
described, providing for the designations, preferences, limitations and
relative, voting, conversion and other rights thereof and the qualifications,
limitations, or restrictions thereof, in addition to those set forth in the
Certificate of Incorporation, all in accordance with the provisions of Section
151 of the Delaware Act:

     RESOLVED, that pursuant to Article IV of the Certificate of Incorporation
as amended, which authorizes the issuance of 112,000,000 shares of stock,
consisting of 100,000,000 shares of common stock, $.001 par value (the "Common
                                                                        ------
Stock"), and 12,000,000 shares of preferred stock, $.001 par value (the
- -----
"Preferred Stock"), the Corporation hereby provides for the issuance of a series
 ---------------
of 4,188,000 shares of Preferred Stock, to be designated as Series B Preferred
Stock (the "Series B Preferred Stock"), and hereby approves the designation,
            ------------------------
issuance, and sale by the Corporation of 4,188,000 shares of the Series B
Preferred Stock and hereby provides for the following designations, preferences,
limitations and relative, voting, conversion, and other rights thereof and the
qualifications, limitations, or restrictions thereof:


     1.  Designation of Series B.  There shall be a series of Preferred Stock
         ------------------------
designated as "Series B Preferred Stock", par value $.001 per share, consisting
of 4,188,000 shares.  Each share of Series B Preferred Stock shall be referred
to herein as a "Series B Preferred Share" or "Share."

                                 Page 1 of 13
<PAGE>

     2.  Voting.  The holder of each share of Series B Preferred Stock shall
         ------
have the right to one vote for each share of Common Stock into which such Series
B Preferred Stock could then be converted as provided hereinbelow, and with
respect to such vote, such holder shall have full voting rights and powers equal
to the voting rights and powers of the holders of Common Stock, and shall be
entitled to notice of any stockholders' meeting in accordance with the bylaws of
the Corporation, and shall be entitled to vote, together with holders of Common
Stock, with respect to any question upon which holders of Common Stock have the
right to vote.  Fractional votes shall not, however, be permitted and any
fractional voting rights available on an as-converted basis (after aggregating
all shares into which shares of Series B Preferred Stock held by each holder
could be converted) shall be rounded to the nearest whole number (with one-half
being rounded upward).

     3.  Protective Provisions.
         ---------------------

         Subject to the rights of other series of Preferred Stock which may
from time to time come into existence, so long as any shares of Series B
Preferred Stock are outstanding, the Corporation shall not without first
obtaining the approval (by vote or written consent, as provided by law) of the
holders of at least fifty percent (50%) of the then outstanding shares of Series
B Preferred Stock, voting together as a class:

               (a) sell, convey, or otherwise dispose of or encumber all or
substantially all of its property or business or merge into or consolidate with
any other corporation (other than a wholly-owned subsidiary corporation) or
affect any other transaction or series of related transactions in which more
than fifty percent (50%) of the voting power of the Corporation is disposed of,
provided that this Section 3(a) shall not apply to a merger effected
- --------
exclusively for the purpose of changing the domicile of the Corporation;

               (b) alter or change the rights, preferences, or privileges of the
shares of Series B Preferred Stock in any manner or exchange, reclassify, or
cancel all or part of the Series B Preferred Stock;

               (c) increase or decrease (other than by redemption or conversion)
the total number of authorized shares of Common Stock or Preferred Stock;

               (d) authorize or issue, or obligate itself to issue, any other
equity security, including any other security convertible into or exercisable
for any equity security having a preference over, or being on a parity with, the
Series B Preferred Stock with respect to redemption, voting, dividends or upon
liquidation;

               (e) perform any act or omission that would result in taxation of
the holders of the Series B Preferred Stock under Section 305 of the Internal
Revenue Code of 1986, as amended; or

               (f) declare or pay any dividend or cancel or modify any dividends
on the Series B Preferred Stock which have been declared but not yet paid.

                                 Page 2 of 13
<PAGE>

               (g) change the authorized number of directors of the Corporation
from seven members;

               (h) authorize the aggregate number of shares of Common Stock that
are available for issuance under the Corporation's 1996 Stock Option and
Restricted Stock Plan to an amount greater than 2,750,000 shares of Common Stock
except as adjusted for stock splits, stock dividends, consolidations,
recapitalizations, and similar events;

               (i) authorize the aggregate number of shares of Common Stock that
are available for issuance under the Corporation's 1996 Non-Employee Director
Stock Option Plan to an amount greater than 100,000 shares of Common Stock
except as adjusted for stock splits, stock dividends, consolidations,
recapitalizations, and similar events;

               (j) authorize or issue any capital stock or rights therefore to
third parties without the prior approval of the Board of Directors of the
Corporation or a duly appointed committee thereof; or

               (k) sell, convey, or otherwise dispose of or encumber all or
substantially all of the Corporation's material intellectual property or
technology rights outside of the ordinary course of business.

     4.  Dividends.  Subject to the rights of other series of Preferred Stock
         ---------
which may from time to time come into existence, the holders of shares of Series
B Preferred Stock shall be entitled to receive dividends, out of any assets
legally available therefor prior and in preference to any declaration or payment
of any dividend (payable other than in Common Stock or other securities and
rights convertible into or entitling the holder thereof to receive, directly or
indirectly, additional shares of Common Stock) on the Common Stock, at the rate
of $0.3056 per share per annum (as adjusted for any stock dividends,
combinations or splits with respect to such shares) on each outstanding share of
Series B Preferred Stock, payable quarterly when, as, and only if declared by
the Board of Directors.  Such dividends shall not be cumulative.

     5.  Liquidation.
         -----------

         (a) Preference. In the event of any liquidation, dissolution or winding
             ----------
up of the Corporation, either voluntary or involuntary, subject to the rights of
other series of Preferred Stock that may from time to time come into existence,
the holders of the Series B Preferred Stock shall be entitled to receive, prior
and in preference to any distribution of any of the assets of the Corporation to
the holders of Common Stock, by reason of and in exchange for their ownership of
the Series B Preferred Stock an amount per share equal to $3.82 per share (as
adjusted for any stock dividends, combinations or splits with respect to such
shares) for each share of Series B Preferred Stock then held by them, plus any
declared but unpaid dividends and any amounts payable pursuant to Section 5(b)
below. If, upon the occurrence of such event, the assets and funds thus
distributed among the holders of the Series A Preferred Stock and the holders of
the Series B Preferred Stock shall be insufficient to permit the payment to such
holders of the full preferential amount each such holder is entitled to receive,
then, subject to the rights of other series of Preferred Stock that may from
time to time come into existence, the entire assets and funds of the Corporation
legally available for distribution shall be distributed

                                 Page 3 of 13
<PAGE>

ratably among the holders of the Series A Preferred Stock and the holders of the
Series B Preferred Stock in proportion to the preferential amount each such
holder is otherwise entitled to receive.

         (b) Remaining Assets. Upon the completion of the distribution required
             ----------------
by Section 5(a) above and any other distribution that may be required with
respect to other series of Preferred Stock that may from time to time come into
existence, the remaining assets of the Corporation available for distribution to
stockholders shall be distributed among the holders of the Common Stock, the
Series A Preferred Stock, the Series B Preferred Stock, and any other class or
series of Preferred Stock that is entitled to share in the residual assets of
the Corporation which shall be distributed pro rata based on the number of
shares of Common Stock held by each (assuming conversion of all such Preferred
Stock).

         (c) Deemed Liquidation. For purposes of this Section 5, a liquidation,
             ------------------
dissolution or winding up of the Corporation shall be deemed to be occasioned
by, or to include, (i) a sale of all or substantially all of the assets of the
Corporation, or (ii) the acquisition of the Corporation by another entity by
means of any transaction or series of related transactions (including, without
limitation, any reorganization, merger or consolidation, but excluding any
merger effected exclusively for the purpose of changing the domicile of the
Corporation) unless the Corporation's stockholders of record as constituted
             ------
immediately prior to such acquisition will, immediately after such acquisition
(by virtue of securities issued as consideration for the Corporation's
acquisition or otherwise) hold at least 50% of the voting power of the surviving
or acquiring entity in approximately the same relative percentages after such
acquisition as before such acquisition.

         (d) Market Value.  In any of the events specified in (c) above, if the
             ------------
consideration received by the Corporation is other than cash, its value will be
deemed its fair market value. Any securities shall be valued as follows:

             (i)   Securities not subject to restrictions on free marketability:

                   (A) If traded on a securities exchange or the Nasdaq National
Market System, the value shall be deemed to be the average of the closing prices
of the securities on such exchange over the thirty-day period ending three (3)
days prior to the closing;

                   (B) If actively traded over-the-counter, the value shall be
deemed to be the average of the closing bid or sale prices (whichever is
applicable) over the thirty-day period ending three (3) days prior to the
closing; and

                   (C) If there is no active public market, the value shall be
the fair market value thereof, as mutually determined by the Corporation and the
holders of at least fifty percent (50%) of the voting power of all then
outstanding shares of Preferred Stock.

             (ii)  The method of valuation of securities subject to restrictions
on free marketability (other than restrictions arising solely by virtue of a
stockholder's status as an affiliate or former affiliate) shall be to make an
appropriate discount from the market value

                                 Page 4 of 13
<PAGE>

determined as above in (i)(A),(B) or (C) to reflect the approximate fair market
value thereof, as mutually determined by the Corporation and the holders of at
least fifty percent (50%) of the voting power of all then outstanding shares of
Preferred Stock.

             (iii) In the event the requirements of Section 5(c) are not
complied with, the Corporation shall forthwith either:

                   (A)  cause such closing to be postponed until such time as
the requirements of this Section 5 have been complied with; or

                   (B)  cancel such transaction, in which event the rights,
preferences and privileges of the holders of the Series B Preferred Stock shall
revert to and be the same as such rights, preferences and privileges existing
immediately prior to the date of the first notice referred to in Section
5(d)(iv) hereof.

             (iv)  The Corporation shall give each holder of record of Series B
Preferred Stock written notice of such impending transaction not later than
twenty (20) days prior to the stockholder's meeting called to approve such
transaction, or twenty (20) days prior to the closing of such transaction,
whichever is earlier, and shall also notify such holders in writing of the final
approval of such transaction. The first of such notices shall describe the
material terms and conditions of the impending transaction and the provisions of
this Section 5, and the Corporation shall thereafter give such holders prompt
notice of any material changes. The transaction shall in no event take place
sooner than twenty (20) days after the corporation has given the first notice
provided for herein or sooner than ten (10) days after the Corporation has given
notice of any material changes provided for herein; provided, however, that such
periods may be shortened upon the written consent of the holders of Preferred
Stock that are entitled to such notice rights or similar notice rights and that
represent at least fifty percent (50%) of the voting power of all then
outstanding shares of such Preferred Stock.

     6.  Conversion.  The holders of the Series B Preferred Stock shall have
         ----------
conversion rights as follows (the "Conversion Rights"):
                                   -----------------

         (a) Right to Convert.  Subject to Section 6(c), each share of Series B
             ----------------
Preferred Stock shall be convertible, at the option of the holder thereof, at
any time after the date of issuance of such share, at the principal corporate
office of the Corporation or any transfer agent for such stock, into such number
of fully paid and nonassessable shares of Common Stock as is determined by
dividing $3.82 by the Conversion Price applicable to such share in effect on the
date the certificate is surrendered for conversion. The initial Conversion Price
per share of Series B Preferred Stock shall be $3.82 (the "Conversion Price").
                                                           ----------------
Such initial Conversion Price shall be subject to adjustment as set forth in
Section 6(d).

         (b) Automatic Conversion. Each share of Series B Preferred Stock shall
             --------------------
automatically be converted, without any further action by the holder of such
shares and whether or not the certificates representing such shares are
surrendered to the Corporation or its transfer agent, into shares of Common
Stock at the Conversion Price at the time in effect for such share immediately
upon the earlier of (i) the Corporation's sale of its Common Stock pursuant to a

                                 Page 5 of 13
<PAGE>

firm commitment underwritten public offering pursuant to an effective
registration statement filed pursuant to the Securities Act of 1933, as amended,
the public offering price of which is not less than $12.00 per share (adjusted
to reflect subsequent stock dividends, stock splits, or recapitalizations) and
which results in aggregate gross cash proceeds to the Corporation of more than
$15,000,000, or (ii) the date specified by written consent or agreement of the
holders of at least fifty percent (50%) of the then outstanding shares of Series
B Preferred Stock.

         (c) Mechanics of Conversion. Before any holder of Series B Preferred
             -----------------------
Stock shall be entitled to convert the same into shares of Common Stock pursuant
to Section 6(a), he shall give written notice at least ten (10) days prior to
the Corporation at its principal corporate office, of the election to convert
the same and shall state therein the name or names in which the certificate or
certificates for shares of Common Stock are to be issued. He shall surrender the
certificate or certificates therefor, duly endorsed, at the office of the
Corporation or of any transfer agent for the Series B Preferred Stock. The
Corporation shall, as soon as practicable thereafter, issue and deliver at such
office to such holder of Series B Preferred Stock, or to the nominee or nominees
of such holder, a certificate or certificates for the number of shares of Common
Stock to which such holder shall be entitled as aforesaid. Such conversion shall
be deemed to have been made immediately prior to the close of business on the
date of such surrender of the shares of Series B Preferred Stock to be
converted, and the person or persons entitled to receive the shares of Common
Stock issuable upon such conversion shall be treated for all purposes as the
record holder or holders of such shares of Common Stock as of such date. If the
conversion is in connection with an underwritten offering of securities
registered pursuant to the Securities Act of 1933, the conversion may, at the
option of any holder tendering Series B Preferred Stock for conversion, be
conditioned upon the closing with the underwriters of the sale of securities
pursuant to such offering, in which event the person(s) entitled to receive
Common Stock upon conversion of such Preferred Stock shall not be deemed to have
converted such Preferred Stock until immediately prior to the closing of such
sale of securities.

         (d)  Conversion Price Adjustments. The Conversion Price of the Series B
              ----------------------------
Preferred Stock shall be subject to adjustment from time to time as follows:

              (i) (A) If the Corporation shall issue, after the date upon which
any shares of Series B Preferred Stock were first issued (the "Purchase Date"),
                                                               -------------
any consideration per share less than the Conversion Price for the Series B
Preferred Stock in effect immediately prior to the issuance of such Additional
Stock, the Conversion Price for the Series B Preferred Stock in effect
immediately prior to such issuance shall automatically (except as otherwise
provided in this clause (i)) be adjusted to a price equal to the product of the
Conversion Price then in effect multiplied by a fraction (x) the numerator of
which is equal to the number of shares of Common Stock outstanding immediately
prior to such event and (y) the denominator of which is equal to the number of
shares of Common Stock outstanding immediately prior to such event plus the
number of shares of Additional Stock actually issued in such transaction.
Notwithstanding the preceding sentence to the contrary, in the event the
Corporation shall issue any Additional Stock within ninety (90) days of the
Purchase Date without consideration or for a consideration per share less than
the Conversion Price for the Series B Preferred Stock in effect immediately
prior to the issuance of such Additional Stock, the Conversion Price for the
Series B Preferred Stock

                                 Page 6 of 13
<PAGE>

in effect immediately prior to the issuance shall automatically be adjusted to a
price equal to the price paid per share for such Additional Stock.

          (B) No adjustment of the Conversion Price for the Series B Preferred
Stock shall be made in an amount less than one cent per share, provided that any
adjustments which are not required to be made by reason of this sentence shall
be carried forward and shall be either taken into account in any subsequent
adjustment made prior to three years from the date of the event giving rise to
the adjustment being carried forward, or shall be made at the end of three years
from the date of the event giving rise to the adjustment being carried forward.
Except to the limited extent provided for in Sections 6(d)(i)(E)(3) and
6(d)(i)(E)(4), no adjustment of such Conversion Price pursuant to this Section
6(d)(i) shall have the effect of increasing the Conversion Price above the
Conversion Price in effect immediately prior to such adjustment.

                    (C) In the case of the issuance of Common Stock for cash,
the consideration shall be deemed to be the amount of cash paid therefor before
deducting any reasonable discounts, commissions or other expenses allowed, paid
or incurred by the Corporation for any underwriting or otherwise in connection
with the issuance and sale thereof.

                    (D) In the case of the issuance of the Common Stock for a
consideration in whole or in part other than cash, the consideration other than
cash shall be deemed to be the fair value thereof as reasonably determined by
the Board of Directors or any committee thereof irrespective of any accounting
treatment.

                    (E) In the case of the issuance (whether before, on or after
the applicable Purchase Date) of options to purchase or rights to subscribe for
Common Stock, securities by their terms convertible into or exchangeable for
Common Stock or options to purchase or rights to subscribe for such convertible
or exchangeable securities, the following provisions shall apply for all
purposes of this Section 6(d)(i) and Section 6(d)(ii):

                    (1) The aggregate maximum number of shares of Common Stock
deliverable upon exercise (assuming the satisfaction of any conditions to
exercisability, including without limitation, the passage of time, but without
taking into account potential antidilution adjustments) of such options to
purchase or rights to subscribe for Common Stock shall be deemed to have been
issued at the time such options or rights were issued and for a consideration
equal to the consideration (determined in the manner provided in Sections
6(d)(i)(C) and 6(d)(i)(D)), if any, received by the Corporation upon the
issuance of such options or rights plus the minimum exercise price provided in
such options or rights (without taking into account potential antidilution
adjustments) for the Common Stock covered thereby.

                    (2) The aggregate maximum number of shares of Common Stock
deliverable upon conversion of or in exchange (assuming the satisfaction of any
conditions to convertibility or exchangeability, including, without limitation,
the passage of time, but without taking into account potential antidilution
adjustments) for any such convertible or exchangeable securities or upon the
exercise of options to purchase or rights to subscribe for such convertible or
exchangeable securities and subsequent conversion or exchange thereof shall be
deemed to have been issued at the time such securities were issued or such
options or rights were issued and

                                 Page 7 of 13
<PAGE>

for a consideration equal to the consideration, if any, received by the
Corporation for any such securities and related options or rights (excluding any
cash received on account of accrued interest or accrued dividends), plus the
minimum additional consideration, if any, to be received by the Corporation
(without taking into account potential antidilution adjustments) upon the
conversion or exchange of such securities or the exercise of any related options
or rights (the consideration in each case to be determined in the manner
provided in Sections 6(d)(i)(C) and 6(d)(i)(D)).

                    (3) In the event of any change in the number of shares of
Common Stock deliverable or in the consideration payable to the Corporation upon
exercise of such options or rights or upon conversion of or in exchange for such
convertible or exchangeable securities, including, but not limited to, a change
resulting from the antidilution provisions thereof, the Conversion Price of the
Series B Preferred Stock, to the extent in any way affected by or computed using
such options, rights or securities, shall be recomputed to reflect such change,
but no further adjustment shall be made for the actual issuance of Common Stock
or any payment of such consideration upon the exercise of any such options or
rights or the conversion or exchange of such securities.

                    (4) Upon the expiration or cancellation of any such options
or rights, the termination of any such rights to convert or exchange or the
expiration of any options or rights related to such convertible or exchangeable
securities, the Conversion Price of the Series B Preferred Stock, to the extent
in any way affected by or computed using such options, rights or securities or
options or rights related to such securities, shall be recomputed to reflect the
issuance of only the number of shares of Common Stock (and convertible or
exchangeable securities which remain in effect) actually issued upon the
exercise of such options or rights, upon the conversion or exchange of such
securities or upon the exercise of the options or rights related to such
securities

                    (5) The number of shares of Common Stock deemed issued and
the consideration deemed paid therefor pursuant to Sections 6(d)(i)(E)(1) and
6(d)(i)(E)(2) shall be appropriately adjusted to reflect any change, termination
or expiration of the type described in either Section 6(d)(i)(E)(3) or
6(d)(i)(E)(4).

               (ii) "Additional Stock" shall mean any shares of Common Stock
                     ----------------
issued (or deemed to have been issued pursuant to Section 6(d)(i)(E) by the
Corporation after the Purchase Date) but specifically excluding:

                    (A) Common Stock issued pursuant to a transaction described
in Section 6(d)(iii) hereof,

                    (B) Shares of Common Stock issuable or issued to employees,
consultants, or directors of the Corporation, directly or pursuant to a stock
option plan or restricted stock plan, all as approved by the Board of Directors
of the Corporation,

                    (C) Capital stock, or options or warrants to purchase
capital stock, issued to financial institutions or lessors in connection with
commercial credit arrangements,

                                 Page 8 of 13

equipment financings or similar transactions, or to vendors or customers in
connection with commercial arrangements, as approved by the Board of Directors
of the Corporation,

                    (D) Capital stock or warrants or options to purchase capital
stock issued in connection with bona fide acquisitions, mergers or similar
transactions, the terms of which are approved by the Board of Directors of the
Corporation,

                    (E) Shares of Common Stock issued or issuable upon
conversion of Preferred Stock,

                    (F) Shares of Common Stock issued or issuable in a public
offering prior to or in connection with which all outstanding shares of Series B
Preferred stock will be converted to Common Stock, and

                    (G) Capital stock, or options or warrants to purchase
capital stock, issued in connection with the licensing or acquisition of
intellectual property or technology rights from third parties, the terms of
which are approved by the Board of Directors of the Corporation.

          (iii)  In the event the Corporation should at any time or from time to
time after the Purchase Date fix a record date for the effectuation of a split
or subdivision of the outstanding shares of Common Stock or the determination of
holders of Common Stock entitled to receive a dividend or other distribution
payable in additional shares of Common Stock or other securities or rights
convertible into, or entitling the holder thereof to receive directly or
indirectly, additional shares of Common Stock (hereinafter referred to as
"Common Stock Equivalents") without payment of any consideration by such holder
 ------------------------
for the additional shares of Common Stock or the Common Stock Equivalents
(including the additional shares of Common Stock issuable upon conversion or
exercise thereof), then, as of such record date (or the date of such dividend
distribution, split or subdivision if no record date is fixed), the Conversion
Price of the Series B Preferred Stock shall be appropriately decreased so that
the number of shares of Common Stock issuable upon conversion of each share of
Series B Preferred Stock shall be increased in proportion to such increase of
the aggregate of shares of Common Stock outstanding and those issuable with
respect to such Common Stock Equivalents with the number of shares issuable with
respect to Common Stock Equivalents determined from time to time in the manner
provided for deemed issuances in Section 6(d)(i)(E).

          (iv)   If the number of shares of Common Stock outstanding at any time
after the Purchase Date is decreased by a combination of the outstanding shares
of Common Stock, then, following the record date of such combination, the
Conversion Price for the Series B Preferred Stock shall be appropriately
increased so that the number of shares of Common Stock issuable upon conversion
of each share of such series shall be decreased in proportion to such decrease
in outstanding shares.

          (e)    Other Distributions. In the event the Corporation shall declare
                 -------------------
a distribution payable in securities of other persons, evidences of indebtedness
issued by the Corporation or other persons, assets (excluding cash dividends) or
options or rights not referred to in Section 6(d)(iii), then, in each such case
for the purpose of this Section 6(e), the holders of

                                 Page 9 of 13
<PAGE>

Series B Preferred Stock shall be entitled to a proportionate share of any such
distribution as though they were the holders of the number of shares of Common
Stock of the Corporation into which their shares of Series B Preferred Stock are
convertible as of the record date fixed for the determination of the holders of
Common Stock of the Corporation entitled to receive such distribution.

          (f)  Recapitalizations. If at any time or from time to time there
               -----------------
shall be a recapitalization of the Common Stock (other than a subdivision,
combination or merger or sale of assets transaction provided for elsewhere in
this Section 6 or Section 5) provision shall be made so that the holders of the
Series B Preferred Stock shall thereafter be entitled to receive upon conversion
of the Series B Preferred Stock the number of shares of stock or other
securities or property of the Company or otherwise, to which a holder of Common
Stock deliverable upon conversion would have been entitled on such
recapitalization. In any such case, appropriate adjustment shall be made in the
application of the provisions of this Section 6 with respect to the rights of
the holders of the Series B Preferred Stock after the recapitalization to the
end that the provisions of this Section 6 (including adjustment of the
Conversion Price then in effect and the number of shares purchasable upon
conversion of the Series B Preferred Stock) shall be applicable after that event
and be as nearly equivalent as practicable.

          (g) No Impairment. The Corporation will not, by amendment of its
              -------------
Certificate of Incorporation or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by the
Corporation, but will at all times in good faith assist in the carrying out of
all the provisions of this Section 6 and in the taking of all such action as may
be necessary or appropriate in order to protect the Conversion Rights of the
holders of Series B Preferred Stock against impairment.

          (h) No Fractional Shares and Certificate as to Adjustments.
              ------------------------------------------------------

                    (i)   No fractional shares shall be issued upon the
conversion of any share or shares of the Series B Preferred Stock, and the
number of shares of Common Stock to be issued shall be rounded to the nearest
whole share. Whether or not fractional shares are issuable upon such conversion
shall be determined on the basis of the total number of shares of Series B
Preferred Stock the holder is at the time converting into Common Stock and the
number of shares of Common Stock issuable upon such aggregate conversion.

                    (ii)  Upon the occurrence of each adjustment or readjustment
of the Conversion Price of Series B Preferred Stock pursuant to this Section 6,
the Corporation, at its expense, shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Series B Preferred Stock a certificate setting forth such adjustment
or readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Corporation shall, upon the written request at any
time of any holder of Series B Preferred Stock, furnish or cause to be furnished
to such holder a like certificate setting forth (A) such adjustment and
readjustment, (B) the Conversion Price for the Series B Preferred Stock at the
time in effect, and (C) the number of shares of Common Stock

                                 Page 10 of 13
<PAGE>

and the amount, if any, of other property which at the time would be received
upon the conversion of a share of the Series B Preferred Stock.

          (i)  Notices of Record Date. In the event of any taking by the
               ----------------------
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, the Corporation
shall mail to each holder of Series B Preferred Stock, at least 20 days prior to
the date specified therein, a notice specifying the date on which any such
record is to be taken for the purpose of such dividend, distribution or right,
and the amount and character of such dividend, distribution or right.

          (j)  Reservation of Stock Issuable Upon Conversion. The Corporation
               ---------------------------------------------
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Series B Preferred Stock, such number of its shares of Common
Stock as shall from time to time be sufficient to effect the conversion of all
outstanding shares of Series B Preferred Stock; and if at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then outstanding shares of Series B Preferred Stock, in
addition to such other remedies as shall be available to the holder of such
Preferred Stock, the Corporation will take such corporate action as may, in the
opinion of its counsel, be necessary to increase its authorized but unissued
shares of Common Stock to such number of shares as shall be sufficient for such
purposes, including, without limitation, engaging in best efforts to obtain the
requisite stockholder approval of any necessary amendment to this Certificate of
Incorporation.

          (k)  Notices. Any notice required by the provisions of this Section 6
               -------
to be given to the holders of shares of Series B Preferred Stock shall be deemed
given if deposited in the United States mail, postage prepaid, and addressed to
each holder of record at his address appearing on the books of the Corporation.

     7.  Redemption.
         ----------

         (a)  Election to Redeem. Subject to the rights of other series of
              ------------------
Preferred Stock which may from time to time come into existence, at any time
after the fourth annual anniversary date of the Purchase Date but not later than
the sixth annual anniversary date of the Purchase Date, the Corporation shall
redeem any Series B Preferred Stock upon receipt by the Corporation (the
"Redemption Date") of a written request from the holders of not less than a
 ---------------
majority of the then outstanding Series B Preferred Stock and receipt
simultaneously therewith of the certificates representing the Series B Preferred
Stock to be redeemed. The Corporation shall, to the extent it may lawfully do
so, redeem, within thirty (30) days of the Redemption Date, the Series B
Preferred Stock by paying in cash therefor a sum equal to $3.82 per share of
Series B Preferred Stock (as adjusted for any stock dividends, combinations or
splits with respect to such shares) plus interest on such amount computed at the
rate of 10% compounded annually from the Purchase Date plus all declared or
accumulated but unpaid dividends on such shares(the "Redemption Price").
                                                     ----------------

                                 Page 11 of 13
<PAGE>

         (b)  Mechanics. Subject to the rights of other series of Preferred
              ---------
Stock which may from time to time come into existence, at least fifteen (15) but
no more than thirty (30) days after the Redemption Date, written notice shall be
mailed by the Corporation, first class postage pre-paid, to each holder of
record (at the close of business on the business day next preceding the day on
which notice is given) of the Series B Preferred Stock to be redeemed, at the
address last shown on the records of the Corporation for such holder, notifying
such holder of the redemption to be effected, specifying the number of shares to
be redeemed from such holder, and the Redemption Price. The Redemption Price of
such shares shall be payable to the order of the person whose name appears on
such certificate or certificates as the owner thereof and each surrendered
certificate shall be cancelled. In the event less than all the shares
represented by any such certificate are redeemed, a new certificate shall be
issued representing the unredeemed shares.

         (c)  Stockholder Rights.  From and after the Redemption Date, all
              ------------------
rights of the holders of shares of Series B Preferred Stock (except the right to
receive the Redemption Price) shall cease with respect to such shares to be
redeemed, and such shares shall not thereafter be transferred on the books of
the Corporation or be deemed to be outstanding for any purpose whatsoever.
Subject to the rights of other series of Preferred Stock which may from time to
time come into existence, if the funds of the Corporation legally available for
redemption of Preferred Stock are insufficient to redeem the total number of
shares of Preferred Stock to be redeemed, those funds which are legally
available will be used to redeem the maximum possible number of such shares
ratably among the holders of such shares to be redeemed based upon the
proportional amount each such holder is entitled to receive.  The shares of
Preferred Stock not redeemed shall remain outstanding and be entitled to all the
rights and preferences provided herein.  Subject to the rights of other series
of Preferred Stock which may from time to time come into existence, at any time
thereafter when additional funds of the Corporation are legally available for
the redemption of shares of Preferred Stock, such funds will immediately be used
to redeem the balance of the shares which the Corporation has become obliged to
redeem on any Redemption Date but which it has not redeemed.

         (d)  Sinking Fund.  No sinking fund shall be established for any
              ------------
redemption of the Series B Preferred Stock.

     8.  Status of Reacquired Series B Preferred Stock.  Series B Preferred
         ---------------------------------------------
Stock issued and reacquired by the Corporation (including by conversion or
redemption) shall have the status of authorized and unissued shares of Preferred
Stock undesignated as to series, subject to later issuance, provided that they
may not be reissued as Series B Preferred Stock.

     9.  Preemptive Rights.  The Series B Preferred Stock is not entitled to
         -----------------
any preemptive or subscription rights in respect of any securities of the
Corporation unless and to the extent provided by written agreement with the
Corporation.

     10. Severability of Provisions.  Whenever possible, each provision hereof
         --------------------------
shall be interpreted in a manner as to be effective and valid under applicable
law, but if any provision hereof is held to be prohibited by or invalid under
applicable law, such provision shall be ineffective only to the extent of such
prohibition or invalidity, without invalidating or adversely affecting the
remaining provisions hereof.

than fifty percent (50%) of the voting power of the Corporation is disposed of,
provided that this Section 3(f) shall not apply to a merger effected
- --------
exclusively for the purpose of changing the domicile of the Corporation;

               (h)  authorize the aggregate number of shares of Common Stock
that are available for issuance under the Corporation's 1996 Stock Option and
Restricted Stock Plan to an amount greater than 4,750,000 shares of Common Stock
except as adjusted for stock splits, stock dividends, consolidations,
recapitalizations, and similar events;

               (i)  authorize or issue any capital stock or rights therefor to
third parties without the prior approval of the Board of Directors of the
Corporation or a duly appointed committee thereof;

               (j)  sell, convey, or otherwise dispose of or encumber all or
substantially of the Corporation's material intellectual property or technology
rights outside of the ordinary course of business; or

               (k)  change the authorized number of directors of the Corporation
from seven (7) members, provided that this Section 3(j) shall not apply unless
                        --------
and until the holders of the Series C Preferred Stock shall have a right to
elect as a class any directors of the Corporation.

     4.  Dividends.  Subject to the rights of other series of Preferred Stock
         ---------
which may from time to time come into existence, the holders of shares of Series
C Preferred Stock shall be entitled to receive dividends, out of any assets
legally available therefor prior and in preference to any declaration or payment
of any dividend (payable other than in Common Stock or other securities and
rights convertible into or entitling the holder thereof to receive, directly or
indirectly, additional shares of Common Stock) on the Common Stock, at the rate
of $0.8248 per share per annum (as adjusted for any stock dividends,
combinations or splits with respect to such shares) on each outstanding share of
Series C Preferred Stock, payable quarterly when, as, and only if declared by
the Board of Directors.  Such dividends shall not be cumulative.

     5.  Liquidation.
         -----------

           (a)  Preference.  In the event of any liquidation, dissolution or
                ----------
winding up of the Corporation, either voluntary or involuntary, subject to the
rights of other series of Preferred Stock that may from time to time come into
existence, the holders of the Series C Preferred Stock shall be entitled to
receive, prior and in preference to any distribution of any of the assets of the
Corporation to the holders of Common Stock, by reason of and in exchange for
their ownership of the Series C Preferred Stock an amount per share equal to
$10.31 per share (as adjusted for any stock dividends, combinations or splits
with respect to such shares) for each

                                 Page 3 of 15
<PAGE>

share of Series C Preferred Stock then held by them, plus any declared but
unpaid dividends. If, upon the occurrence of such event, the assets and funds
thus distributed among the holders of the Series A Preferred Stock, the Series B
Preferred Stock, and the Series C Preferred Stock shall be insufficient to
permit the payment to such holders of the full preferential amount each such
holder is entitled to receive, then, subject to the rights of other series of
Preferred Stock that may from time to time come into existence, the entire
assets and funds of the Corporation legally available for distribution shall be
distributed ratably among the holders of the Series A Preferred Stock, the
Series B Preferred Stock, and the Series C Preferred Stock in proportion to the
preferential amount each such holder is otherwise entitled to receive.

           (b)  Deemed Liquidation.  For purposes of this Section 5, a
                ------------------
liquidation, dissolution or winding up of the Corporation shall be deemed to be
occasioned by, or to include, (i) a sale of all or substantially all of the
assets of the Corporation, or (ii) the acquisition of the Corporation by another
entity by means of any transaction or series of related transactions (including,
without limitation, any reorganization, merger or consolidation, but excluding
any merger effected exclusively for the purpose of changing the domicile of the
Corporation) unless the Corporation's stockholders of record as constituted
             ------
immediately prior to such acquisition will, immediately after such acquisition
(by virtue of securities issued as consideration for the Corporation's
acquisition or otherwise) hold at least 50% of the voting power of the surviving
or acquiring entity in approximately the same relative percentages after such
acquisition as before such acquisition.

           (c)  Market Value.  In any of the events specified in (b) above, if
                ------------
the consideration received by the Corporation is other than cash, its value will
be deemed its fair market value. Any securities shall be valued as follows:

           (i)  Securities not subject to restrictions on free marketability:

                   (A)  If traded on a securities exchange or the Nasdaq
National Market System, the value shall be deemed to be the average of the
closing prices of the securities on such exchange over the thirty-day period
ending three (3) days prior to the closing;

                   (B)  If actively traded over-the-counter, the value shall be
deemed to be the average of the closing bid or sale prices (whichever is
applicable) over the thirty-day period ending three (3) days prior to the
closing; and

                   (C)  If there is no active public market, the value shall be
the fair market value thereof, as mutually determined by the Corporation and the
holders of at least fifty percent (50%) of the voting power of all then
outstanding shares of Preferred Stock.

           (ii) The method of valuation of securities subject to restrictions on
free marketability (other than restrictions arising solely by virtue of a
stockholder's status as an affiliate or former affiliate) shall be to make an
appropriate discount from the market value determined as above in (i)(A),(B) or
(C) to reflect the approximate fair market value thereof, as mutually determined
by the Corporation and the holders of at least fifty percent (50%) of the voting
power of all then

                                 Page 4 of 15
<PAGE>

outstanding shares of Preferred Stock.

           (iii) In the event the requirements of Section 5(b) are not complied
with, the Corporation shall forthwith either:

                   (A)  cause such closing to be postponed until such time as
the requirements of this Section 5 have been complied with; or

                   (B)  cancel such transaction, in which event the rights,
preferences and privileges of the holders of the Series C Preferred Stock shall
revert to and be the same as such rights, preferences and privileges existing
immediately prior to the date of the first notice referred to in Section
5(c)(iv) hereof.

           (iv)  The Corporation shall give each holder of record of Series C
Preferred Stock written notice of such impending transaction not later than
twenty (20) days prior to the stockholder's meeting called to approve such
transaction, or twenty (20) days prior to the closing of such transaction,
whichever is earlier, and shall also notify such holders in writing of the final
approval of such transaction. The first of such notices shall describe the
material terms and conditions of the impending transaction and the provisions of
this Section 5, and the Corporation shall thereafter give such holders prompt
notice of any material changes. The transaction shall in no event take place
sooner than twenty (20) days after the corporation has given the first notice
provided for herein or sooner than ten (10) days after the Corporation has given
notice of any material changes provided for herein; provided, however, that such
periods may be shortened upon the written consent of the holders of Preferred
Stock that are entitled to such notice rights or similar notice rights and that
represent at least fifty percent (50%) of the voting power of all then
outstanding shares of such Preferred Stock.

     6.  Conversion.  The holders of the Series C Preferred Stock shall have
         ----------
conversion rights as follows (the "Conversion Rights"):
                                   -----------------

           (a)  Right to Convert.  Subject to Section 6(c), each share of
                ----------------
Series C Preferred Stock shall be convertible, at the option of the holder
thereof, at any time after the date of issuance of such share, at the principal
corporate office of the Corporation or any transfer agent for such stock, into
such number of fully paid and nonassessable shares of Common Stock as is
determined by dividing $10.31 by the Conversion Price applicable to such share
in effect on the date the certificate is surrendered for conversion. The initial
Conversion Price per share of Series C Preferred Stock shall be $10.31 (the
"Conversion Price"). Such initial Conversion Price shall be subject to
 ----------------
adjustment as set forth in Section 6(d).

         (b)  Automatic Conversion.  Each share of Series C Preferred Stock
              --------------------
shall automatically be converted, without any further action by the holder of
such shares and whether or not the certificates representing such shares are
surrendered to the Corporation or its transfer agent, into shares of Common
Stock at the Conversion Price at the time in effect for such share immediately
upon the earlier of (i) the Corporation's sale of its Common Stock pursuant to a
firm commitment underwritten public offering pursuant to an effective
registration statement

                                 Page 5 of 15
<PAGE>

filed pursuant to the Securities Act of 1933, as amended, (a "Public Offering")
                                                              ---------------
provided the public offering price is not less than $12.00 per share (adjusted
to reflect stock dividends, stock splits, or recapitalizations) and which
results in aggregate gross cash proceeds to the Corporation of not less than
$35,000,000, (ii) a Public Offering that does not satisfy either the per share
price or the cash proceeds requirements of (b)(i) but is a Public Offering in
which all of the then outstanding shares of Series A Preferred Stock and Series
B Preferred Stock are converted either automatically or voluntarily into shares
of Common Stock, or (iii)the date specified by written consent or agreement of
the holders of at least two-thirds (66.67%) of the then outstanding shares of
Series C Preferred Stock.

         (c)  Mechanics of Conversion.  Before any holder of Series C Preferred
              -----------------------
Stock shall be entitled to convert the same into shares of Common Stock pursuant
to Section 6(a), he shall give written notice at least ten (10) days prior to
the Corporation at its principal corporate office, of the election to convert
the same and shall state therein the name or names in which the certificate or
certificates for shares of Common Stock are to be issued. He shall surrender the
certificate or certificates therefor, duly endorsed, at the office of the
Corporation or of any transfer agent for the Series C Preferred Stock. The
Corporation shall, as soon as practicable thereafter, issue and deliver at such
office to such holder of Series C Preferred Stock, or to the nominee or nominees
of such holder, a certificate or certificates for the number of shares of Common
Stock to which such holder shall be entitled as aforesaid. Such conversion shall
be deemed to have been made immediately prior to the close of business on the
date of such surrender of the shares of Series C Preferred Stock to be
converted, and the person or persons entitled to receive the shares of Common
Stock issuable upon such conversion shall be treated for all purposes as the
record holder or holders of such shares of Common Stock as of such date. If the
conversion is in connection with an underwritten offering of securities
registered pursuant to the Securities Act of 1933, the conversion may, at the
option of any holder tendering Series C Preferred Stock for conversion, be
conditioned upon the closing with the underwriters of the sale of securities
pursuant to such offering, in which event the person(s) entitled to receive
Common Stock upon conversion of such Preferred Stock shall not be deemed to have
converted such Preferred Stock until immediately prior to the closing of such
sale of securities.

         (d)  Conversion Price Adjustments.  The Conversion Price of the Series
              ----------------------------
C  Preferred Stock shall be subject to adjustment from time to time as follows:

         (i)(A)  If the Corporation shall issue, after the date upon which
any shares of Series C Preferred Stock are first issued (the "Purchase Date"),
                                                              -------------
any Additional Stock (as defined below) without consideration or for a
consideration per share less than the Conversion Price for the Series C
Preferred Stock in effect immediately prior to the issuance of such Additional
Stock, the Conversion Price for the Series C Preferred Stock in effect
immediately prior to such issuance shall automatically (except as otherwise
provided in this clause (i)) be adjusted to a price equal to the product of the
Conversion Price then in effect multiplied by a fraction (x) the numerator of
which is equal to the number of shares of Common Stock outstanding immediately
prior to such event and (y) the denominator of which is equal to the number of
shares of Common Stock outstanding immediately prior to such event plus the
number of shares of Additional Stock actually issued in such transaction.

                                 Page 6 of 15
<PAGE>

                   (B)  No adjustment of the Conversion Price for the Series C
Preferred Stock shall be made in an amount less than one cent per share,
provided that any adjustments which are not required to be made by reason of
this sentence shall be carried forward and shall be either taken into account in
any subsequent adjustment made within three (3) years from the date of the event
giving rise to the adjustment being carried forward, or shall be made at the end
of three years from the date of the event giving rise to the adjustment being
carried forward. Except to the limited extent provided for in Sections
6(d)(i)(E)(3) and 6(d)(i)(E)(4), no adjustment of such Conversion Price pursuant
to this Section 6(d)(i) shall have the effect of increasing the Conversion Price
above the Conversion Price in effect immediately prior to such adjustment.

                   (C)  In the case of the issuance of Common Stock for cash,
the consideration shall be deemed to be the amount of cash paid therefor before
deducting any reasonable discounts, commissions or other expenses allowed, paid
or incurred by the Corporation for any underwriting or otherwise in connection
with the issuance and sale thereof.

                   (D)  In the case of the issuance of the Common Stock for a
consideration in whole or in part other than cash, the consideration other than
cash shall be deemed to be the fair value thereof as reasonably determined by
the Board of Directors or any committee thereof irrespective of any accounting
treatment.

                   (E)  In the case of the issuance (whether before, on or after
the applicable Purchase Date) of options to purchase or rights to subscribe for
Common Stock, securities by their terms convertible into or exchangeable for
Common Stock or options to purchase or rights to subscribe for such convertible
or exchangeable securities, the following provisions shall apply for all
purposes of this Section 6(d)(i) and Section 6(d)(ii):

                         (1) The aggregate maximum number of shares of Common
Stock deliverable upon exercise (assuming the satisfaction of any conditions to
exercisability, including without limitation, the passage of time, but without
taking into account potential antidilution adjustments) of such options to
purchase or rights to subscribe for Common Stock shall be deemed to have been
issued at the time such options or rights were issued and for a consideration
equal to the consideration (determined in the manner provided in Sections
6(d)(i)(C) and 6(d)(i)(D)), if any, received by the Corporation upon the
issuance of such options or rights plus the minimum exercise price provided in
such options or rights (without taking into account potential antidilution
adjustments) for the Common Stock covered thereby.

                         (2) The aggregate maximum number of shares of Common
Stock deliverable upon conversion of or in exchange (assuming the satisfaction
of any conditions to convertibility or exchangeability, including, without
limitation, the passage of time, but without taking into account potential
antidilution adjustments) for any such convertible or exchangeable securities or
upon the exercise of options to purchase or rights to subscribe for such
convertible or exchangeable securities and subsequent conversion or exchange
thereof shall be deemed to have been issued at the time such securities were
issued or such options or rights were issued and for a consideration equal to
the consideration, if any, received by the Corporation for any such

                                 Page 7 of 15
<PAGE>

securities and related options or rights (excluding any cash received on account
of accrued interest or accrued dividends), plus the minimum additional
consideration, if any, to be received by the Corporation (without taking into
account potential antidilution adjustments) upon the conversion or exchange of
such securities or the exercise of any related options or rights (the
consideration in each case to be determined in the manner provided in Sections
6(d)(i)(C) and 6(d)(i)(D)).

                         (3) In the event of any change in the number of shares
of Common Stock deliverable or in the consideration payable to the Corporation
upon exercise of such options or rights or upon conversion of or in exchange for
such convertible or exchangeable securities, including, but not limited to, a
change resulting from the antidilution provisions thereof, the Conversion Price
of the Series C Preferred Stock, to the extent in any way affected by or
computed using such options, rights or securities, shall be recomputed to
reflect such change, but no further adjustment shall be made for the actual
issuance of Common Stock or any payment of such consideration upon the exercise
of any such options or rights or the conversion or exchange of such securities.

                         (4) any options or rights related to such convertible
or exchangeable securities, the Conversion Price of the Series C Preferred
Stock, to the extent in any way affected by or computed using such options,
rights or securities or options or rights related to such securities, shall be
recomputed to reflect the issuance of only the number of shares of Common Stock
(and convertible or exchangeable securities which remain in effect) actually
issued upon the exercise of such options or rights, upon the conversion or
exchange of such securities or upon the exercise of the options or rights
related to such securities.

                         (5) The number of shares of Common Stock deemed issued
and the consideration deemed paid therefor pursuant to Sections 6(d)(i)(E)(1)
and 6(d)(i)(E)(2) shall be appropriately adjusted to reflect any change,
termination or expiration of the type described in either Section 6(d)(i)(E)(3)
or 6(d)(i)(E)(4).

         (ii) "Additional Stock" shall mean any shares of Common Stock issued
               ----------------
(or deemed to have been issued pursuant to Section 6(d)(i)(E) by the Corporation
after the Purchase Date) but specifically excluding:

               (A)  Common Stock issued pursuant to a transaction described in
Section 6(d)(iii) hereof,

               (B)  Shares of Common Stock issuable or issued to employees,
consultants, or directors of the Corporation directly or pursuant to a stock
option plan or restricted stock plan all as approved on or before the Purchase
Date by the Board of Directors of the Corporation,

               (C)  Shares of Common Stock issuable or issued to employees,
consultants, or directors of the Corporation pursuant to a stock option plan or
restricted stock plan approved

                                 Page 8 of 15
<PAGE>

subsequent to the Purchase Date by the Board of Directors of the Corporation,

               (D)  Capital stock, or options or warrants to purchase capital
stock, issued to financial institutions or lessors in connection with commercial
credit arrangements, equipment financings or similar transactions, or to vendors
or customers in connection with commercial arrangements, as approved by the
Board of Directors of the Corporation,

               (E)  Capital stock or warrants or options to purchase capital
stock issued in connection with bona fide strategic partnering transactions or
acquisitions, the terms of which are approved by the Board of Directors of the
Corporation,

               (F)  Capital stock or warrants or options to purchase capital
stock issued in connection with mergers or similar transactions, the terms of
which are approved by the Board of Directors of the Corporation,

               (G)  Shares of Common Stock issued or issuable upon conversion of
Preferred Stock,

               (H)  Shares of Common Stock issued or issuable in a public
offering prior to or in connection with which all outstanding shares of Series C
Preferred stock are converted to Common Stock, and

               (I)  Capital stock, or options or warrants to purchase capital
stock, issued in connection with the licensing or acquisition of intellectual
property or technology rights from third parties, the terms of which are
approved by the Board of Directors of the Corporation.

         Notwithstanding the preceding provisions of this Section 6(d)(ii) to
the contrary, Additional Stock shall include the aggregate amount of shares of
Common Stock, if any, issued pursuant to subsections (C), (D), (E), (F) or (I)
above to the extent such shares exceed an amount equal to fifteen percent (15%)
of the number of shares of Common Stock outstanding thirty (30) days after the
Purchase Date (such number to be computed on a fully diluted basis and as
adjusted for any stock dividends, combinations or splits with respect to such
shares).

               (iii) In the event the Corporation should at any time or from
time to time after the Purchase Date fix a record date for the effectuation of a
split or subdivision of the outstanding shares of Common Stock or the
determination of holders of Common Stock entitled to receive a dividend or other
distribution payable in additional shares of Common Stock or other securities or
rights convertible into, or entitling the holder thereof to receive directly or
indirectly, additional shares of Common Stock (hereinafter referred to as
"Common Stock Equivalents") without payment of any consideration by such holder
 ------------------------
for the additional shares of Common Stock or the Common Stock Equivalents
(including the additional shares of Common Stock issuable upon conversion or
exercise thereof), then, as of such record date (or the date of such dividend
distribution, split or subdivision if no record date is fixed), the Conversion
Price of the Series C Preferred Stock shall be appropriately decreased so that
the number of shares of Common Stock issuable upon conversion of each share of
Series C Preferred Stock shall be increased in

                                 Page 9 of 15
<PAGE>

proportion to such increase of the aggregate of shares of Common Stock
outstanding and those issuable with respect to such Common Stock Equivalents
with the number of shares issuable with respect to Common Stock Equivalents
determined from time to time in the manner provided for deemed issuances in
Section 6(d)(i)(E).

               (iv) If the number of shares of Common Stock outstanding at any
time after the Purchase Date is decreased by a combination of the outstanding
shares of Common Stock, then, following the record date of such combination, the
Conversion Price for the Series C Preferred Stock shall be appropriately
increased so that the number of shares of Common Stock issuable upon conversion
of each share of Series C Preferred Stock shall be decreased in proportion to
such decrease in outstanding shares.

               (v)( A)  In the event the Corporation completes a Public Offering
within one eighty (180) days of the Purchase Date in which the public offering
price is not less than $12.00 per share (to be adjusted to reflect stock
dividends, combinations or splits) and which results in aggregate cash proceeds
to the Corporation of not less than $35,000,000 (collectively, a "Qualified
                                                                  ---------
Public Offering") then the Conversion Price for purposes of Section 6(b) shall
- ---------------
be calculated by (x) multiplying the Market Valuation of the Corporation
(defined below) by sixty percent (60%), (y) then subtracting from such product
the sum of the gross proceeds received by the Corporation for the sale of the
Series C Preferred Stock plus sixty percent (60%) of the aggregate amount of any
additional private equity financings of the Corporation which occur subsequent
to the Purchase Date, (z) and dividing the difference between (x) and (y) by the
number of shares of Common Stock outstanding immediately prior to the Purchase
Date (such number to be computed on a fully diluted basis and adjusted for any
stock dividends, combinations or splits with respect to the Common Stock).  For
purposes of this subsection, Market Valuation shall mean the product of the per
share price as established in the Qualified Public Offering multiplied by the
total number of shares of Common Stock outstanding on a fully diluted basis.

               (B)  Notwithstanding the preceding subparagraph (A) to the
contrary, such Conversion Price shall not be greater than $10.31 per share nor
less than $6.88 per share (such limits to be adjusted accordingly for any stock
dividends, combinations or splits with respect to the Common Stock).

               (C)  In the event the Company fails to complete a Qualified
Public Offering or in the event of an automatic conversion pursuant to Section
6(b)(ii) above then the Conversion Price will be adjusted to the lower of (i)
$6.88 per share (to be adjusted for any stock dividends, combinations or splits
with respect to the Common Stock) or (ii) the Public Offering price per share of
Common Stock in an initial Public Offering but in no event less than $5.55 per
share (to be adjusted for any stock dividends, combinations or splits with
respect to the Common Stock).

          (e)  Other Distributions.  In the event the Corporation shall declare
               -------------------
a distribution payable in securities of other persons, evidences of indebtedness
issued by the Corporation or other persons, assets (excluding cash dividends) or
options or rights not referred to in Section 6(d)(iii), then, in each such case
for the purpose of this Section 6(e), the holders of Series C

                                 Page 10 of 15
<PAGE>

Preferred Stock shall be entitled to a proportionate share of any such
distribution as though they were the holders of the number of shares of Common
Stock of the Corporation into which their shares of Series C Preferred Stock are
convertible as of the record date fixed for the determination of the holders of
Common Stock of the Corporation entitled to receive such distribution.

               (f)  Recapitalizations.  If at any time or from time to time
                    -----------------
there shall be a recapitalization of the Common Stock (other than a subdivision,
combination or merger or sale of assets transaction provided for elsewhere in
this Section 6 or Section 5) provision shall be made so that the holders of the
Series C Preferred Stock shall thereafter be entitled to receive upon conversion
of the Series C Preferred Stock the number of shares of stock or other
securities or property of the Company or otherwise, to which a holder of Common
Stock deliverable upon conversion would have been entitled on such
recapitalization. In any such case, appropriate adjustment shall be made in the
application of the provisions of this Section 6 with respect to the rights of
the holders of the Series C Preferred Stock after the recapitalization to the
end that the provisions of this Section 6 (including adjustment of the
Conversion Price then in effect and the number of shares purchasable upon
conversion of the Series C Preferred Stock) shall be applicable after that event
and be as nearly equivalent as practicable.

               (g)  No Impairment.  The Corporation will not, by amendment of
                    -------------
its Certificate of Incorporation or through any reorganization,
recapitalization, transfer of assets, consolidation, merger, dissolution, issue
or sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Corporation, but will at all times in good faith assist in the
carrying out of all the provisions of this Section 6 and in the taking of all
such action as may be necessary or appropriate in order to protect the
Conversion Rights of the holders of Series C Preferred Stock against impairment.

               (h)  No Fractional Shares and Certificate as to Adjustments.
                    ------------------------------------------------------

                     (i)    No fractional shares shall be issued upon the
conversion of any share or shares of the Series C Preferred Stock, and the
number of shares of Common Stock to be issued shall be rounded to the nearest
whole share. Whether or not fractional shares are issuable upon such conversion
shall be determined on the basis of the total number of shares of Series C
Preferred Stock the holder is at the time converting into Common Stock and the
number of shares of Common Stock issuable upon such aggregate conversion.

                     (ii)   Upon the occurrence of each adjustment or
readjustment of the Conversion Price of Series C Preferred Stock pursuant to
this Section 6, the Corporation, at its expense, shall promptly compute such
adjustment or readjustment in accordance with the terms hereof and prepare and
furnish to each holder of Series C Preferred Stock a certificate setting forth
such adjustment or readjustment and showing in detail the facts upon which such
adjustment or readjustment is based. The Corporation shall, upon the written
request at any time of any holder of Series C Preferred Stock, furnish or cause
to be furnished to such holder a like certificate setting forth (A) such
adjustment and readjustment, (B) the Conversion Price for the

                                 Page 11 of 15
<PAGE>

Series C Preferred Stock at the time in effect, and (C) the number of shares of
Common Stock and the amount, if any, of other property which at the time would
be received upon the conversion of a share of the Series C Preferred Stock.

               (i)  Notices of Record Date.  In the event of any taking by the
                    ----------------------
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, the Corporation
shall mail to each holder of Series C Preferred Stock, at least twenty (20) days
prior to the date specified therein, a notice specifying the date on which any
such record is to be taken for the purpose of such dividend, distribution or
right, and the amount and character of such dividend, distribution or right.

               (j)  Reservation of Stock Issuable Upon Conversion.  The
                    ---------------------------------------------
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock, solely for the purpose of effecting the
conversion of the shares of the Series C Preferred Stock, such number of its
shares of Common Stock as shall from time to time be sufficient to effect the
conversion of all outstanding shares of Series C Preferred Stock; and if at any
time the number of authorized but unissued shares of Common Stock shall not be
sufficient to effect the conversion of all then outstanding shares of Series C
Preferred Stock, in addition to such other remedies as shall be available to the
holder of such Preferred Stock, the Corporation will take such corporate action
as may, in the opinion of its counsel, be necessary to increase its authorized
but unissued shares of Common Stock to such number of shares as shall be
sufficient for such purposes, including, without limitation, engaging in best
efforts to obtain the requisite stockholder approval of any necessary amendment
to this Certificate of Incorporation.

               (k)  Notices.  Any notice required by the provisions of this
                    -------
Section 6 to be given to the holders of shares of Series C Preferred Stock shall
be deemed given if deposited in the United States mail, postage prepaid, and
addressed to each holder of record at his address appearing on the books of the
Corporation.

     7.  Redemption.
         ----------

               (a)  Election to Redeem. Subject to the rights of other series
                    ------------------
of Preferred Stock which may from time to time come into existence, at any time
after the fourth annual anniversary date of the Purchase Date but not later than
the sixth annual anniversary date of the Purchase Date, the Corporation shall
redeem any Series C Preferred Stock upon receipt by the Corporation (the
"Redemption Date") of a written request from any holder of Series C Preferred
 ---------------
Stock and receipt simultaneously therewith of the certificate(s) representing
the Series C Preferred Stock to be redeemed. The Corporation shall, to the
extent it may lawfully do so, redeem, within thirty (30) days of the Redemption
Date, the Series C Preferred Stock requested to be redeemed by paying in cash
therefor a sum equal to $10.31 per share of Series C Preferred Stock (as
adjusted for any stock dividends, combinations or splits with respect to such
shares) plus interest on such amount computed at the rate of 10% compounded
annually from the Purchase Date plus all declared or accumulated but unpaid
dividends on such shares(the "Redemption Price").
                              ----------------

                                 Page 12 of 15
<PAGE>

               (b)  Mechanics.  Subject to the rights of other series of
                    ---------
Preferred Stock which may from time to time come into existence, at least
fifteen (15) but no more than thirty (30) days after the Redemption Date,
written notice shall be mailed by the Corporation, first class postage pre-paid,
to each holder of record (at the close of business on the business day next
preceding the day on which notice is given) of the Series C Preferred Stock to
be redeemed, at the address last shown on the records of the Corporation for
such holder, notifying such holder of the redemption to be effected, specifying
the number of shares to be redeemed from such holder, and the Redemption Price.
The Redemption Price of such shares shall be payable to the order of the person
whose name appears on such certificate or certificates as the owner thereof and
each surrendered certificate shall be cancelled. In the event less than all the
shares represented by any such certificate are redeemed, a new certificate shall
be issued representing the unredeemed shares.

               (c)  Stockholder Rights.  From and after the Redemption Date,
                    ------------------
all rights of the holders of shares of Series C Preferred Stock to be redeemed
(except the right to receive the Redemption Price) shall cease with respect to
such shares to be redeemed, and such shares shall not thereafter be transferred
on the books of the Corporation or be deemed to be outstanding for any purpose
whatsoever. Subject to the rights of other series of Preferred Stock which may
from time to time come into existence, if the funds of the Corporation legally
available for redemption of Preferred Stock are insufficient to redeem the total
number of shares of Preferred Stock to be redeemed, those funds which are
legally available will be used to redeem the maximum possible number of such
shares ratably among the holders of such shares to be redeemed based upon the
proportional amount each such holder is entitled to receive. The shares of
Preferred Stock not redeemed shall remain outstanding and be entitled to all the
rights and preferences provided herein. Subject to the rights of other series of
Preferred Stock which may from time to time come into existence, at any time
thereafter when additional funds of the Corporation are legally available for
the redemption of shares of Preferred Stock, such funds will immediately be used
to redeem the balance of the shares which the Corporation has become obliged to
redeem on any Redemption Date but which it has not redeemed.

               (d)  Sinking Fund.  No sinking fund shall be established for any
                    ------------
redemption of the Series C Preferred Stock.

     8.  Status of Reacquired Series C Preferred Stock.  Series C Preferred
         ---------------------------------------------
Stock issued and reacquired by the Corporation (including by conversion or
redemption) shall have the status of authorized and unissued shares of Preferred
Stock undesignated as to series, subject to later issuance, provided that they
may not be reissued as Series C Preferred Stock.

     9.  Preemptive Rights.  The Series C Preferred Stock is not entitled to
         -----------------
any preemptive or subscription rights in respect of any securities of the
Corporation unless and to the extent provided by written agreement with the
Corporation.

     10. Severability of Provisions.  Whenever possible, each provision hereof
         --------------------------
shall be interpreted in a manner as to be effective and valid under applicable
law, but if any provision hereof is held

                                 Page 13 of 15
<PAGE>

to be prohibited by or invalid under applicable law, such provision shall be
ineffective only to the extent of such prohibition or invalidity, without
invalidating or adversely affecting the remaining provisions hereof.

                              E-STAMP CORPORATION

                           INDEMNIFICATION AGREEMENT

          This Indemnification Agreement ("Agreement") is entered into as of the
___ day of August, 1999 by and between E-Stamp Corporation, a Delaware
corporation (the "Company"), and __________ ("Indemnitee").

                                    RECITALS
                                    --------

          A.  The Company and Indemnitee recognize the continued difficulty in
obtaining liability insurance for its directors, officers, employees, agents and
fiduciaries, the significant increases in the cost of such insurance and the
general reductions in the coverage of such insurance.

          B.  The Company and Indemnitee further recognize the substantial
increase in corporate litigation in general, subjecting directors, officers,
employees, agents and fiduciaries to expensive litigation risks at the same time
as the availability and coverage of liability insurance has been severely
limited.

          C.  Indemnitee does not regard the current protection available as
adequate under the present circumstances, and Indemnitee and other directors,
officers, employees, agents and fiduciaries of the Company may not be willing to
continue to serve in such capacities without additional protection.

          D.  The Company desires to attract and retain the services of highly
qualified individuals, such as Indemnitee, to serve the Company and, in part, in
order to induce Indemnitee to continue to provide services to the Company,
wishes to provide for the indemnification and advancing of expenses to
Indemnitee to the maximum extent permitted by law.

          E.  In view of the considerations set forth above, the Company desires
that Indemnitee be indemnified by the Company as set forth herein.

          NOW, THEREFORE, the Company and Indemnitee hereby agree as follows:

          1.   Indemnification.
               ---------------

                  (a) Indemnification of Expenses.  The Company shall
                      ---------------------------
indemnify Indemnitee to the fullest extent permitted by law if Indemnitee was or
is or becomes a party to or witness or other participant in, or is threatened to
be made a party to or witness or other participant in, any threatened, pending
or completed action, suit, proceeding or alternative dispute resolution
mechanism, or any hearing, inquiry or investigation that Indemnitee in good
faith believes might lead to the institution of any such action, suit,
proceeding or alternative dispute resolution mechanism, whether civil, criminal,
administrative, investigative or other (hereinafter a "Claim") by reason of (or
arising in part out of) any event or occurrence related to the fact that
Indemnitee is or was a director, officer, employee, agent or fiduciary of the
Company, or any subsidiary of the Company, or is or was
<PAGE>

serving at the request of the Company as a director, officer, employee, agent or
fiduciary of another corporation, partnership, joint venture, trust or other
enterprise, or by reason of any action or inaction on the part of Indemnitee
while serving in such capacity (hereinafter an "Indemnifiable Event") against
any and all expenses (including attorneys' fees and all other costs, expenses
and obligations incurred in connection with investigating, defending, being a
witness in or participating in (including on appeal), or preparing to defend, be
a witness in or participate in, any such action, suit, proceeding, alternative
dispute resolution mechanism, hearing, inquiry or investigation), judgments,
fines, penalties and amounts paid in settlement (if such settlement is approved
in advance by the Company, which approval shall not be unreasonably withheld) of
such Claim and any federal, state, local or foreign taxes imposed on Indemnitee
as a result of the actual or deemed receipt of any payments under this Agreement
(collectively, hereinafter "Expenses"), including all interest, assessments and
other charges paid or payable in connection with or in respect of such Expenses.
Such payment of Expenses shall be made by the Company as soon as practicable but
in any event no later than five days after written demand by Indemnitee therefor
is presented to the Company.

                  (b) Reviewing Party.  Notwithstanding the foregoing, (i) the
                      ---------------
obligations of the Company under Section 1(a) shall be subject to the condition
that the Reviewing Party (as described in Section 10(e) hereof) shall not have
determined (in a written opinion, in any case in which the Independent Legal
Counsel referred to in Section 1(c) hereof is involved) that Indemnitee would
not be permitted to be indemnified under applicable law, and (ii) the obligation
of the Company to make an advance payment of Expenses to Indemnitee pursuant to
Section 2(a) (an "Expense Advance") shall be subject to the condition that, if,
when and to the extent that the Reviewing Party determines that Indemnitee would
not be permitted to be so indemnified under applicable law, the Company shall be
entitled to be reimbursed by Indemnitee (who hereby agrees to reimburse the
Company) for all such amounts theretofore paid; provided, however, that if
Indemnitee has commenced or thereafter commences legal proceedings in a court of
competent jurisdiction to secure a determination that Indemnitee should be
indemnified under applicable law, any determination made by the Reviewing Party
that Indemnitee would not be permitted to be indemnified under applicable law
shall not be binding and Indemnitee shall not be required to reimburse the
Company for any Expense Advance until a final judicial determination is made
with respect thereto (as to which all rights of appeal therefrom have been
exhausted or lapsed). Indemnitees' obligation to reimburse the Company for any
Expense Advance shall be unsecured and no interest shall be charged thereon. If
there has not been a Change in Control (as defined in Section 10(c) hereof), the
Reviewing Party shall be selected by the Board of Directors, and if there has
been such a Change in Control (other than a Change in Control which has been
approved by a majority of the Company's Board of Directors who were directors
immediately prior to such Change in Control), the Reviewing Party shall be the
Independent Legal Counsel referred to in Section 1(c) hereof. If there has been
no determination by the Reviewing Party or if the Reviewing Party determines
that Indemnitee substantively would not be permitted to be indemnified in whole
or in part under applicable law, Indemnitee shall have the right to commence
litigation seeking an initial determination by the court or challenging any such
determination by the Reviewing Party or any aspect thereof, including the legal
or factual bases therefor, and the Company hereby consents to service of process
and to appear in any such proceeding. Any determination by the Reviewing Party
otherwise shall be conclusive and binding on the Company and Indemnitee.

                                      -2-
<PAGE>

                  (c) Change in Control.  The Company agrees that if there is
                      -----------------
a Change in Control of the Company (other than a Change in Control which has
been approved by a majority of the Company's Board of Directors who were
directors immediately prior to such Change in Control) then, with respect to all
matters thereafter arising concerning the rights of Indemnitees to payments of
Expenses and Expense Advances under this Agreement or any other agreement or
under the Company's Certificate of Incorporation or Bylaws as now or hereafter
in effect, Independent Legal Counsel (as defined in Section 10(d) hereof) shall
be selected by Indemnitee and approved by the Company (which approval shall not
be unreasonably withheld). Such counsel, among other things, shall render its
written opinion to the Company and Indemnitee as to whether and to what extent
Indemnitee would be permitted to be indemnified under applicable law and the
Company agrees to abide by such opinion. The Company agrees to pay the
reasonable fees of the Independent Legal Counsel referred to above and to fully
indemnify such counsel against any and all expenses (including attorneys' fees),
claims, liabilities and damages arising out of or relating to this Agreement or
its engagement pursuant hereto.

                  (d) Mandatory Payment of Expenses.  Notwithstanding any
                      -----------------------------
other provision of this Agreement other than Section 9 hereof, to the extent
that Indemnitee has been successful on the merits or otherwise, including,
without limitation, the dismissal of an action without prejudice, in defense of
any action, suit, proceeding, inquiry or investigation referred to in Section
(1)(a) hereof or in the defense of any claim, issue or matter therein,
Indemnitee shall be indemnified against all Expenses incurred by Indemnitee in
connection therewith.

          2.   Expenses; Indemnification Procedure.
               -----------------------------------

                  (a) Advancement of Expenses.  The Company shall advance all
                      -----------------------
Expenses incurred by Indemnitee. The advances to be made hereunder shall be paid
by the Company to Indemnitee as soon as practicable but in any event no later
than five days after written demand by Indemnitee therefor to the Company.

                  (b) Notice/Cooperation by Indemnitee.  Indemnitee shall, as
                      --------------------------------
a condition precedent to Indemnitees' right to be indemnified under this
Agreement, give the Company notice in writing as soon as practicable of any
Claim made against Indemnitee for which indemnification will or could be sought
under this Agreement. Notice to the Company shall be directed to the Chief
Executive Officer of the Company at the address shown on the signature page of
this Agreement (or such other address as the Company shall designate in writing
to Indemnitee). In addition, Indemnitee shall give the Company such information
and cooperation as it may reasonably require and as shall be within Indemnitees'
power.

                  (c) No Presumptions; Burden of Proof.  For purposes of this
                      --------------------------------
Agreement, the termination of any Claim by judgment, order, settlement (whether
with or without court approval) or conviction, or upon a plea of nolo
                                                                 ----
contendere, or its equivalent, shall not create a presumption that Indemnitee
- ----------
did not meet any particular standard of conduct or have any particular belief or
that a court has determined that indemnification is not permitted by applicable
law. In addition, neither the failure of the Reviewing Party to have made a
determination as to whether Indemnitee has met any

                                      -3-
<PAGE>

particular standard of conduct or had any particular belief, nor an actual
determination by the Reviewing Party that Indemnitee has not met such standard
of conduct or did not have such belief, prior to the commencement of legal
proceedings by Indemnitee to secure a judicial determination that Indemnitee
should be indemnified under applicable law, shall be a defense to Indemnitee's
claim or create a presumption that Indemnitee has not met any particular
standard of conduct or did not have any particular belief. In connection with
any determination by the Reviewing Party or otherwise as to whether Indemnitee
is entitled to be indemnified hereunder, the burden of proof shall be on the
Company to establish that Indemnitee is not so entitled.

                  (d) Notice to Insurers.  If, at the time of the receipt by
                      ------------------
the Company of a notice of a Claim pursuant to Section 2(b) hereof, the Company
has liability insurance in effect which may cover such Claim, the Company shall
give prompt notice of the commencement of such Claim to the insurers in
accordance with the procedures set forth in the respective policies. The Company
shall thereafter take all necessary or desirable action to cause such insurers
to pay, on behalf of Indemnitee, all amounts payable as a result of such action,
suit, proceeding, inquiry or investigation in accordance with the terms of such
policies.

                  (e) Selection of Counsel.  In the event the Company shall be
                      --------------------
obligated hereunder to pay the Expenses of any Claim, the Company shall be
entitled to assume the defense of such Claim with counsel approved by
Indemnitee, which approval shall not be unreasonably withheld, upon the delivery
to Indemnitee of written notice of its election so to do. After delivery of such
notice, approval of such counsel by Indemnitee and the retention of such counsel
by the Company, the Company will not be liable to Indemnitee under this
Agreement for any fees of counsel subsequently incurred by Indemnitee with
respect to the same Claim; provided that, (i) Indemnitee shall have the right to
employ Indemnitees' counsel in any such Claim at Indemnitee expense and (ii) if
(A) the employment of counsel by Indemnitee has been previously authorized by
the Company, (B) Indemnitee shall have reasonably concluded that there is a
conflict of interest between the Company and Indemnitee in the conduct of any
such defense, or (C) the Company shall not continue to retain such counsel to
defend such Claim, then the fees and expenses of Indemnitee counsel shall be at
the expense of the Company. The Company shall have the right to conduct such
defense as it sees fit in its sole discretion, including the right to settle any
claim against Indemnitee without the consent of the Indemnitee.

          3.   Additional Indemnification Rights; Nonexclusivity.
               -------------------------------------------------

                  (a) Scope.  The Company hereby agrees to indemnify
                      -----
Indemnitee to the fullest extent permitted by law, notwithstanding that such
indemnification is not specifically authorized by the other provisions of this
Agreement, the Company's Certificate of Incorporation, the Company's Bylaws or
by statute. In the event of any change after the date of this Agreement in any
applicable law, statute or rule which expands the right of a Delaware
corporation to indemnify a member of its Board of Directors or an officer,
employee, agent or fiduciary, it is the intent of the parties hereto that
Indemnitee shall enjoy by this Agreement the greater benefits afforded by such
change. In the event of any change in any applicable law, statute or rule which
narrows the right of a Delaware corporation to indemnify a member of its Board
of Directors or an officer, employee, agent or

                                      -4-
<PAGE>

fiduciary, such change, to the extent not otherwise required by such law,
statute or rule to be applied to this Agreement, shall have no effect on this
Agreement or the parties' rights and obligations hereunder except as set forth
in Section 8(a) hereof.

                  (b) Nonexclusivity.  The indemnification provided by this
                      --------------
Agreement shall be in addition to any rights to which Indemnitee may be entitled
under the Company's Certificate of Incorporation, its Bylaws, any agreement, any
vote of stockholders or disinterested directors, the General Corporation Law of
the State of Delaware, or otherwise. The indemnification provided under this
Agreement shall continue as to Indemnitee for any action Indemnitee took or did
not take while serving in an indemnified capacity even though Indemnitee may
have ceased to serve in such capacity.

          4.   No Duplication of Payments.  The Company shall not be liable
               --------------------------
under this Agreement to make any payment in connection with any Claim made
against Indemnitee to the extent Indemnitee has otherwise actually received
payment (under any insurance policy, Certificate of Incorporation, Bylaw or
otherwise) of the amounts otherwise indemnifiable hereunder.

          5.   Partial Indemnification.  If Indemnitee is entitled under any
               -----------------------
provision of this Agreement to indemnification by the Company for some or a
portion of Expenses incurred in connection with any Claim, but not, however, for
all of the total amount thereof, the Company shall nevertheless indemnify
Indemnitee for the portion of such Expenses to which Indemnitee are entitled.

          6.   Mutual Acknowledgement.  Both the Company and Indemnitee
               ----------------------
acknowledge that in certain instances, Federal law or applicable public policy
may prohibit the Company from indemnifying its directors, officers, employees,
agents or fiduciaries under this Agreement or otherwise. Indemnitee understands
and acknowledges that the Company has undertaken or may be required in the
future to undertake with the Securities and Exchange Commission to submit the
question of indemnification to a court in certain circumstances for a
determination of the Company's right under public policy to indemnify
Indemnitee.

          7.   Liability Insurance.  To the extent the Company maintains
               -------------------
liability insurance applicable to directors, officers, employees, agents or
fiduciaries, Indemnitee shall be covered by such policies in such a manner as to
provide Indemnitee the same rights and benefits as are accorded to the most
favorably insured of the Company's directors, if Indemnitee is a director; or of
the Company's officers, if Indemnitee is not a director of the Company but is an
officer; or of the Company's key employees, agents or fiduciaries, if Indemnitee
is not an officer or director but is a key employee, agent or fiduciary.

          8.   Exceptions.  Any other provision herein to the contrary
               ----------
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

                (a) Excluded Action or Omissions.  To indemnify Indemnitee for
                    ----------------------------
Indemnitee's acts, omissions or transactions from which Indemnitee or the
Indemnitee may not be relieved of liability under applicable law;

                                      -5-
<PAGE>

                  (b) Claims Initiated by Indemnitee.  To indemnify or advance
                      ------------------------------
expenses to Indemnitee with respect to Claims initiated or brought voluntarily
by Indemnitee and not by way of defense, except (i) with respect to actions or
proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other agreement or insurance policy or under the Company's
Certificate of Incorporation or Bylaws now or hereafter in effect relating to
Claims for Indemnifiable Events, (ii) in specific cases if the Board of
Directors has approved the initiation or bringing of such Claim, or (iii) as
otherwise required under Section 145 of the Delaware General Corporation Law,
regardless of whether Indemnitee ultimately is determined to be entitled to such
indemnification, advance expense payment or insurance recovery, as the case may
be;

                  (c) Lack of Good Faith.  To indemnify Indemnitee for any
                      ------------------
expenses incurred by Indemnitee with respect to any proceeding instituted by
Indemnitee to enforce or interpret this Agreement, if a court of competent
jurisdiction determines that each of the material assertions made by Indemnitee
in such proceeding was not made in good faith or was frivolous; or

                  (d) Claims Under Section 16(b).  To indemnify Indemnitee for

employee, agent or fiduciary of such constituent corporation, or is or was
serving at the request of such constituent corporation as a director, officer,
employee, agent or fiduciary of another corporation, partnership, joint venture,
employee benefit plan, trust or other enterprise, Indemnitee shall stand in the
same position under the provisions of this Agreement with respect to the

respect to an employee benefit plan, its participants or its beneficiaries;
and if Indemnitee acted in good faith and in a manner Indemnitee reasonably
believed to be in the interest of the participants and beneficiaries of an
employee benefit plan, Indemnitee shall be deemed to have acted in a manner "not
opposed to the best interests of the Company" as referred to in this Agreement.

                  (c) For purposes of this Agreement a "Change in Control" shall
be deemed to have occurred if (i) any "person" (as such term is used in Sections
13(d) and 14(d) of the Securities Exchange Act of 1934, as amended), other than
a trustee or other fiduciary holding securities under an employee benefit plan
of the Company or a corporation owned directly or indirectly by the stockholders
of the Company in substantially the same proportions as their ownership of stock

defined in Rule 13d-3 under said Act), directly or indirectly, of securities of
the Company representing more than 20% of the total voting power represented by

Board of Directors or nomination for election by the Company's stockholders was
approved by a vote of at least two-thirds of the directors then still in office
who either were directors at the beginning of the period or whose election or
nomination for election was previously so approved, cease for any reason to
constitute a majority thereof, or (iii) the stockholders of the Company approve
a merger or consolidation of the Company with any other corporation other than a
merger or consolidation which would result in the Voting Securities of the
Company outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into Voting Securities of the
surviving entity) at least 80% of the total voting power represented by the
Voting Securities of the Company or such surviving entity outstanding
immediately after such merger or consolidation, or the stockholders of the
Company approve a plan of complete liquidation of the Company or an agreement
for the sale or disposition by the Company of (in one transaction or a series of
transactions) all or substantially all of the Company's assets.

                  (d) For purposes of this Agreement, "Independent Legal
Counsel" shall mean an attorney or firm of attorneys, selected in accordance
with the provisions of Section 1(c) hereof, who shall not have otherwise
performed services for the Company or Indemnitee within the last three years
(other than with respect to matters concerning the rights of Indemnitee under

               ---------------------------------------
this Agreement shall be construed as giving Indemnitee any right to be retained
in the employ of the Company or any of its subsidiaries.

of an Option or Stock Purchase Right that number of Shares having a Fair Market
Value equal to (or lesser than) the minimum amount required to be withheld.  The
Fair Market Value of the Shares to be withheld shall be determined on the date
that the amount of tax to be withheld is to be determined.  All elections by an
Optionee to have Shares withheld for this purpose shall be made in such form and
under such conditions as the Administrator may deem necessary or advisable;

           (x)    to authorize any person to execute on behalf of the Company
any instrument required to effect the grant of an Option or Stock Purchase Right
previously granted by the Administrator; and

           (xi)   to make all other determinations deemed necessary or advisable
for administering the Plan.

       (c) Effect of Administrator's Decision.  The Administrator's decisions,
           ----------------------------------
determinations and interpretations shall be final and binding on all Optionees
and any other holders of Options or Stock Purchase Rights.

    5. Eligibility.  Nonstatutory Stock Options and Stock Purchase Rights may
       -----------
be granted to Service Providers. Incentive Stock Options may be granted only to
Employees.

      6.  Limitations.
          -----------

          (a) Each Option shall be designated in the Option Agreement as either
an Incentive Stock Option or a Nonstatutory Stock Option.  However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options.  For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted.  The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

          (b) Neither the Plan nor any Option or Stock Purchase Right shall
confer upon an Optionee any right with respect to continuing the Optionee's
relationship as a Service Provider with the Company, nor shall they interfere in
any way with the Optionee's right or the Company's right to terminate such
relationship at any time, with or without cause.

          (c) The following limitations shall apply to grants of Options:

              (i)   No Service Provider shall be granted, in any fiscal year of
the Company, Options to purchase more than 1,500,000 Shares.

              (ii)  In connection with his or her initial service, a Service
Provider may be granted Options to purchase up to an additional 1,500,000 Shares
which shall not count against the limit set forth in subsection (i) above.

              (iii) The foregoing limitations shall be adjusted proportionately
in connection with any change in the Company's capitalization as described in
Section 13.

      7.  Term of Plan. Subject to Section 19 of the Plan, the Plan shall become
          ------------
effective upon its adoption by the Board. It shall continue in effect for a term
of ten (10) years unless terminated earlier under Section 15 of the Plan.

      8.  Term of Option.  The term of each Option shall be stated in the Option
          --------------
Agreement. In the case of an Incentive Stock Option, the term shall be ten (10)
years from the date of grant or such shorter term as may be provided in the
Option Agreement. Moreover, in the case of an Incentive Stock Option granted to
an Optionee who, at the time the Incentive Stock Option is granted, owns stock
representing more than ten percent (10%) of the total combined voting power of
all classes of stock of the Company or any Parent or Subsidiary, the term of the
Incentive Stock Option shall be five (5) years from the date of grant or such
shorter term as may be provided in the Option Agreement.

<PAGE>

      9.  Option Exercise Price and Consideration.
          ---------------------------------------

          (a) Exercise Price.  The per share exercise price for the Shares to be
              --------------
issued pursuant to exercise of an Option shall be determined by the
Administrator, subject to the following:

              (i)   In the case of an Incentive Stock Option

                    (A) granted to an Employee who, at the time the Incentive
Stock Option is granted, owns stock representing more than ten percent (10%) of
the voting power of all classes of stock of the Company or any Parent or
Subsidiary, the per Share exercise price shall be no less than 110% of the Fair
Market Value per Share on the date of grant.

                    (B) granted to any Employee other than an Employee described
in paragraph (A) immediately above, the per Share exercise price shall be no
less than 100% of the Fair Market Value per Share on the date of grant.

              (ii)  In the case of a Nonstatutory Stock Option the per Share
exercise price shall be determined by the Administrator. In the case of a
Nonstatutory Stock Option intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

              (iii) Notwithstanding the foregoing, Options may be granted with a
per Share exercise price of less than 100% of the Fair Market Value per Share on
the date of grant pursuant to a merger or other corporate transaction.

          (b) Waiting Period and Exercise Dates.  At the time an Option is
              ---------------------------------
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions that must be satisfied before the
Option may be exercised.

          (c) Form of Consideration.  The Administrator shall determine the
              ---------------------
acceptable form of consideration for exercising an Option, including the method
of payment.  In the case of an Incentive Stock Option, the Administrator shall
determine the acceptable form of consideration at the time of grant.  Such
consideration may consist entirely of:

              (i)  cash;

              (ii)  check;

              (iii) promissory note;

              (iv)  other Shares which (A) in the case of Shares acquired upon
exercise of an option, have been owned by the Optionee for more than six months
on the date of surrender, and (B) have a Fair Market Value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised;

                                      -7-
<PAGE>

          (v)    consideration received by the Company under a cashless exercise
program implemented by the Company in connection with the Plan;

          (vi)   a reduction in the amount of any Company liability to the
Optionee, including any liability attributable to the Optionee's participation
in any Company-sponsored deferred compensation program or arrangement;

          (vii)  any combination of the foregoing methods of payment; or

          (viii) such other consideration and method of payment for the issuance
of Shares to the extent permitted by Applicable Laws.

     10.  Exercise of Option.
          ------------------

          (a) Procedure for Exercise; Rights as a Stockholder. Any Option
              -----------------------------------------------
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement.  Unless the Administrator provides in writing
otherwise, vesting of Options granted hereunder shall be tolled during any
unpaid leave of absence.  An Option may not be exercised for a fraction of a
Share.

              An Option shall be deemed exercised when the Company receives: (i)
written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a stockholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 13 of the Plan.

              Exercising an Option in any manner shall decrease the number of
Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

          (b) Termination of Relationship as a Service Provider.  If an Optionee
              -------------------------------------------------
ceases to be a Service Provider, other than upon the Optionee's death or
Disability, the Optionee may exercise his or her Option within such period of
time as is specified in the Option Agreement to the extent that the Option is
vested on the date of termination (but in no event later than the expiration of
the term of such Option as set forth in the Option Agreement).  In the absence
of a specified time in the Option Agreement, the Option shall remain exercisable
for three (3) months following the Optionee's termination.  If, on the date of
termination, the Optionee is not vested as to his or her

                                      -8-
<PAGE>

entire Option, the Shares covered by the unvested portion of the Option shall
revert to the Plan. If, after termination, the Optionee does not exercise his or
her Option within the time specified by the Administrator, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

          (c) Disability of Optionee.  If an Optionee ceases to be a Service
              ----------------------
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option Agreement
to the extent the Option is vested on the date of termination (but in no event
later than the expiration of the term of such Option as set forth in the Option
Agreement).  In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the Optionee's
termination.  If, on the date of termination, the Optionee is not vested as to
his or her entire Option, the Shares covered by the unvested portion of the
Option shall revert to the Plan.  If, after termination, the Optionee does not
exercise his or her Option within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

          (d) Death of Optionee.  If an Optionee dies while a Service Provider,
              -----------------
the Option may be exercised within such period of time as is specified in the
Option Agreement (but in no event later than the expiration of the term of such
Option as set forth in the Notice of Grant), by the Optionee's estate or by a
person who acquires the right to exercise the Option by bequest or inheritance,
but only to the extent that the Option is vested on the date of death.  In the
absence of a specified time in the Option Agreement, the Option shall remain
exercisable for twelve (12) months following the Optionee's termination.  If, at
the time of death, the Optionee is not vested as to his or her entire Option,
the Shares covered by the unvested portion of the Option shall immediately
revert to the Plan.  The Option may be exercised by the executor or
administrator of the Optionee's estate or, if none, by the person(s) entitled to
exercise the Option under the Optionee's will or the laws of descent or
distribution.  If the Option is not so exercised within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

          (e) Buyout Provisions.  The Administrator may at any time offer to buy
              -----------------
out for a payment in cash or Shares an Option previously granted based on such
terms and conditions as the Administrator shall establish and communicate to the
Optionee at the time that such offer is made.

     11.  Stock Purchase Rights.
          ---------------------

          (a) Rights to Purchase.  Stock Purchase Rights may be issued either
              ------------------
alone, in addition to, or in tandem with other awards granted under the Plan
and/or cash awards made outside of the Plan.  After the Administrator determines
that it will offer Stock Purchase Rights under the Plan, it shall advise the
offeree in writing or electronically, by means of a Notice of Grant, of the
terms, conditions and restrictions related to the offer, including the number of
Shares that the offeree shall be entitled to purchase, the price to be paid, and
the time within which the offeree must accept such offer.  The offer shall be
accepted by execution of a Restricted Stock Purchase Agreement in the form
determined by the Administrator.

                                      -9-
<PAGE>

          (b) Repurchase Option.  Unless the Administrator determines otherwise,
              -----------------
the Restricted Stock Purchase Agreement shall grant the Company a repurchase
option exercisable upon the voluntary or involuntary termination of the
purchaser's service with the Company for any reason (including death or
Disability).  The purchase price for Shares repurchased pursuant to the
Restricted Stock Purchase Agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company.  The repurchase option shall lapse at a rate determined by the
Administrator.

          (c) Other Provisions.  The Restricted Stock Purchase Agreement shall
              ----------------
contain such other terms, provisions and conditions not inconsistent with the
Plan as may be determined by the Administrator in its sole discretion.

          (d) Rights as a Stockholder.  Once the Stock Purchase Right is
              -----------------------
exercised, the purchaser shall have the rights equivalent to those of a
stockholder, and shall be a stockholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company.  No adjustment
will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 13
of the Plan.

     12.  Non-Transferability of Options and Stock Purchase Rights.  Unless
          --------------------------------------------------------
determined otherwise by the Administrator, an Option or Stock Purchase Right may
not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any
manner other than by will or by the laws of descent or distribution and may be
exercised, during the lifetime of the Optionee, only by the Optionee.  If the
Administrator makes an Option or Stock Purchase Right transferable, such Option
or Stock Purchase Right shall contain such additional terms and conditions as
the Administrator deems appropriate.

     13.  Adjustments Upon Changes in Capitalization, Dissolution, Merger or
          ------------------------------------------------------------------
Asset Sale.
- ----------

          (a) Changes in Capitalization.  Subject to any required action by the
              -------------------------
stockholders of the Company, the number of shares of Common Stock covered by
each outstanding Option and Stock Purchase Right, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right, as well as the price per share of Common Stock covered by each
such outstanding Option or Stock Purchase Right, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration."  Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option or Stock
Purchase Right.

                                      -10-
<PAGE>

          (b) Dissolution or Liquidation.  In the event of the proposed
              --------------------------
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction.  The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until thirty (30) days prior to
such transaction as to all of the Optioned Stock covered thereby, including
Shares as to which the Option would not otherwise be exercisable.  In addition,
the Administrator may provide that any Company repurchase option applicable to
any Shares purchased upon exercise of an Option or Stock Purchase Right shall
lapse as to all such Shares, provided the proposed dissolution or liquidation
takes place at the time and in the manner contemplated.  To the extent it has
not been previously exercised, an Option or Stock Purchase Right will terminate
immediately prior to the consummation of such proposed action.

          (c) Merger or Asset Sale.  In the event of a merger of the Company
              --------------------
with or into another corporation, or the sale of substantially all of the assets
of the Company, each outstanding Option and Stock Purchase Right shall be
assumed or an equivalent option or right substituted by the successor
corporation or a Parent or Subsidiary of the successor corporation.  In the
event that the successor corporation refuses to assume or substitute for the
Option or Stock Purchase Right, the Optionee shall fully vest in and have the
right to exercise the Option or Stock Purchase Right as to all of the Optioned
Stock, including Shares as to which it would not otherwise be vested or
exercisable.  If an Option or Stock Purchase Right becomes fully vested and
exercisable in lieu of assumption or substitution in the event of a merger or
sale of assets, the Administrator shall notify the Optionee in writing or
electronically that the Option or Stock Purchase Right shall be fully vested and
exercisable for a period of thirty (30) days from the date of such notice, and
the Option or Stock Purchase Right shall terminate upon the expiration of such
period.  For the purposes of this paragraph, the Option or Stock Purchase Right
shall be considered assumed if, following the merger or sale of assets, the
option or right confers the right to purchase or receive, for each Share of
Optioned Stock subject to the Option or Stock Purchase Right immediately prior
to the merger or sale of assets, the consideration (whether stock, cash, or
other securities or property) received in the merger or sale of assets by
holders of Common Stock for each Share held on the effective date of the
transaction (and if holders were offered a choice of consideration, the type of
consideration chosen by the holders of a majority of the outstanding Shares);
provided, however, that if such consideration received in the merger or sale of
assets is not solely common stock of the successor corporation or its Parent,
the Administrator may, with the consent of the successor corporation, provide
for the consideration to be received upon the exercise of the Option or Stock
Purchase Right, for each Share of Optioned Stock subject to the Option or Stock
Purchase Right, to be solely common stock of the successor corporation or its
Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger or sale of assets.

     14.  Date of Grant.  The date of grant of an Option or Stock Purchase Right
          -------------
shall be, for all purposes, the date on which the Administrator makes the
determination granting such Option or Stock Purchase Right, or such other later
date as is determined by the Administrator.  Notice of the determination shall
be provided to each Optionee within a reasonable time after the date of such
grant.

                                      -11-
<PAGE>

     15.  Amendment and Termination of the Plan.
          -------------------------------------

          (a) Amendment and Termination.  The Board may at any time amend,
              -------------------------
alter, suspend or terminate the Plan.

          (b) Stockholder Approval.  The Company shall obtain stockholder
              --------------------
approval of any Plan amendment to the extent necessary and desirable to comply
with Applicable Laws.

          (c) Effect of Amendment or Termination.  No amendment, alteration,
              ----------------------------------
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to Options granted under the
Plan prior to the date of such termination.

     16.  Conditions Upon Issuance of Shares.
          ----------------------------------

          (a) Legal Compliance.  Shares shall not be issued pursuant to the
              ----------------
exercise of an Option or Stock Purchase Right unless the exercise of such Option
or Stock Purchase Right and the issuance and delivery of such Shares shall
comply with Applicable Laws and shall be further subject to the approval of
counsel for the Company with respect to such compliance.

          (b) Investment Representations.  As a condition to the exercise of an
              --------------------------
Option or Stock Purchase Right, the Company may require the person exercising
such Option or Stock Purchase Right to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required.

     17.  Inability to Obtain Authority.  The inability of the Company to obtain
          -----------------------------
authority from any regulatory body having jurisdiction, which authority is
deemed by the Company's counsel to be necessary to the lawful issuance and sale
of any Shares hereunder, shall relieve the Company of any liability in respect
of the failure to issue or sell such Shares as to which such requisite authority
shall not have been obtained.

     18.  Reservation of Shares.  The Company, during the term of this Plan,
          ---------------------
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

     19.  Stockholder Approval. The Plan shall be subject to approval by the
          --------------------
stockholders of the Company within twelve (12) months after the date the Plan is
adopted.  Such stockholder approval shall be obtained in the manner and to the
degree required under Applicable Laws.

II.  AGREEMENT
     ---------

       A. Grant of Option.
          ---------------

          The Plan Administrator of the Company hereby grants to the Optionee
named in the Notice of Grant attached as Part I of this Agreement (the
"Optionee") an option (the "Option") to purchase the number of Shares, as set
forth in the Notice of Grant, at the exercise price per share set forth in the
Notice of Grant (the "Exercise Price"), subject to the terms and conditions of
the Plan, which is incorporated herein by reference.  Subject to Section 15(c)
of the Plan, in the event of a conflict between the terms and conditions of the
Plan and the terms and conditions of this Option Agreement, the terms and
conditions of the Plan shall prevail.

          If designated in the Notice of Grant as an Incentive Stock Option
("ISO"), this Option is intended to qualify as an Incentive Stock Option under
Section 422 of the Code.  However, if this Option is intended to be an Incentive
Stock Option, to the extent that it exceeds the $100,000 rule of Code Section
422(d) it shall be treated as a Nonstatutory Stock Option ("NSO").

       B. Exercise of Option.
          ------------------

          (a) Right to Exercise.  This Option is exercisable during its term in
              -----------------
accordance with the Vesting Schedule set out in the Notice of Grant and the
applicable provisions of the Plan and this Option Agreement.

          (b) Method of Exercise.  This Option is exercisable by delivery of an
              ------------------
exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
which shall state the election to exercise the Option, the number of Shares in
respect of which the Option is being exercised (the "Exercised Shares"), and
such other representations and agreements as may be required by the Company
pursuant to the provisions of the Plan.  The Exercise Notice shall be completed
by the Optionee and delivered to the Stock Plan Administrator of the Company.
The Exercise Notice shall be accompanied by payment of the aggregate Exercise
Price as to all Exercised Shares.  This Option shall be deemed to be exercised
upon receipt by the Company of such fully executed Exercise Notice accompanied
by such aggregate Exercise Price.

              No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise complies with Applicable Laws.  Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.

<PAGE>

       C. Method of Payment.
          ------------------

          Payment of the aggregate Exercise Price shall be by any of the
following, or a combination thereof, at the election of the Optionee:

          1.   cash; or

          2.   check; or

          3.   surrender of other Shares which (i) in the case of Shares
acquired upon exercise of an option, have been owned by the Optionee for more
than six (6) months on the date of surrender, and (ii) have a Fair Market Value
on the date of surrender equal to the aggregate Exercise Price of the Exercised
Shares; or

          4.   to the extent permitted by the Administrator, delivery of a
properly executed exercise notice together with such other documentation as the
Administrator and the broker, if applicable, shall require to effect an exercise
of the Option and delivery to the Company of the sale proceeds required to pay
the Exercise Price.

       D. Non-Transferability of Option.
          ------------------------------

          This Option may not be transferred in any manner otherwise than by
will or by the laws of descent or distribution and may be exercised during the
lifetime of Optionee only by the Optionee.  The terms of the Plan and this
Option Agreement shall be binding upon the executors, administrators, heirs,
successors and assigns of the Optionee.

       E. Term of Option.
          ---------------

          This Option may be exercised only within the term set out in the
Notice of Grant, and may be exercised during such term only in accordance with
the Plan and the terms of this Option Agreement.

       F. Tax Consequences.
          -------------------

          Some of the federal tax consequences relating to this Option, as of
the date of this Option, are set forth below.  THIS SUMMARY IS NECESSARILY
INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  THE
OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING
OF THE SHARES.

       G. Exercising the Option.
          ----------------------

          1.   Nonstatutory Stock Option.  The Optionee may incur regular
               -------------------------
federal income tax liability upon exercise of a NSO.  The Optionee will be
treated as having received compensation income (taxable at ordinary income tax
rates) equal to the excess, if any, of the Fair Market Value of the Exercised
Shares on the date of exercise over their aggregate Exercise Price.  If the
Optionee is an Employee or a former Employee, the Company will be required to
withhold from his or her compensation or collect from Optionee and pay to the
applicable taxing authorities an amount in

                                      -3-
<PAGE>

cash equal to a percentage of this compensation income at the time of exercise,
and may refuse to honor the exercise and refuse to deliver Shares if such
withholding amounts are not delivered at the time of exercise.

          2.   Incentive Stock Option.  If this Option qualifies as an ISO, the
               ----------------------
Optionee will have no regular federal income tax liability upon its exercise,
although the excess, if any, of the Fair Market Value of the Exercised Shares on
the date of exercise over their aggregate Exercise Price will be treated as an
adjustment to alternative minimum taxable income for federal tax purposes and
may subject the Optionee to alternative minimum tax in the year of exercise.  In
the event that the Optionee ceases to be an Employee but remains a Service
Provider, any Incentive Stock Option of the Optionee that remains unexercised
shall cease to qualify as an Incentive Stock Option and will be treated for tax
purposes as a Nonstatutory Stock Option on the date three (3) months and one (1)
day following such change of status.

          3.   Disposition of Shares.
               ---------------------

               (a) NSO.  If the Optionee holds NSO Shares for at least one year,
                   ---
any gain realized on disposition of the Shares will be treated as long-term
capital gain for federal income tax purposes.

               (b) ISO.  If the Optionee holds ISO Shares for at least one year
                   ---
after exercise and two years after the grant date, any gain realized on
disposition of the Shares will be treated as long-term capital gain for federal
income tax purposes. If the Optionee disposes of ISO Shares within one year
after exercise or two years after the grant date, any gain realized on such
disposition will be treated as compensation income (taxable at ordinary income
rates) to the extent of the excess, if any, of the lesser of (A) the difference
between the Fair Market Value of the Shares acquired on the date of exercise and
the aggregate Exercise Price, or (B) the difference between the sale price of
such Shares and the aggregate Exercise Price. Any additional gain will be taxed
as capital gain, short-term or long-term depending on the period that the ISO
Shares were held.

               (c) Notice of Disqualifying Disposition of ISO Shares.  If
                   -------------------------------------------------
the Optionee sells or otherwise disposes of any of the Shares acquired pursuant
to an ISO on or before the later of (i) two years after the grant date, or (ii)
one year after the exercise date, the Optionee shall immediately notify the
Company in writing of such disposition. The Optionee agrees that he or she may
be subject to income tax withholding by the Company on the compensation income
recognized from such early disposition of ISO Shares by payment in cash or out
of the current earnings paid to the Optionee.

     H.   Entire Agreement; Governing Law.
          --------------------------------

          The Plan is incorporated herein by reference.  The Plan and this
Option Agreement constitute the entire agreement of the parties with respect to

hereof, and may not be modified adversely to the Optionee's interest except by

          The following constitute the provisions of the 1999 Employee Stock

provisions of the Plan, accordingly, shall be construed so as to extend and
limit participation in a manner consistent with the requirements of that section
of the Code.

continuing intact while the individual is on sick leave or other leave of
absence approved by the Company.  Where the period of leave exceeds 90 days and

          (b) Any provisions of the Plan to the contrary notwithstanding, no

date as the Board shall determine, and continuing thereafter until terminated in

Offering Periods (including the commencement dates thereof) with respect to
future offerings without shareholder approval if such change is announced at
least five (5) days prior to the scheduled beginning of the first Offering
Period to be affected thereafter.

     5.   Participation.
          -------------

          (a) An eligible Employee may become a participant in the Plan by
completing a subscription agreement authorizing payroll deductions in the form
of Exhibit A to this Plan and filing it with the Company's payroll office prior
to the applicable Enrollment Date.

                                      -3-
<PAGE>

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

     6.   Payroll Deductions.
          ------------------

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

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

          (c) A participant may discontinue his or her participation in the Plan
as provided in Section 10 hereof, or may increase or decrease the rate of his or
her payroll deductions during the Offering Period by completing or filing with
the Company a new subscription agreement authorizing a change in payroll
deduction rate; provided, however, that a participant may increase or decrease
the rate of his or her payroll deductions only once during each Purchase Period.
The Board may, in its discretion, limit the number of participation rate changes
during any Offering Period.  The change in rate shall be effective with the
first full payroll period following five (5) business days after the Company's
receipt of the new subscription agreement unless the Company elects to process a
given change in participation more quickly.  A participant's subscription
agreement shall remain in effect for successive Offering Periods unless
terminated as provided in Section 10 hereof.

          (d) Notwithstanding the foregoing, to the extent necessary to comply
with Section 423(b)(8) of the Code and Section 3(b) hereof, a participant's
payroll deductions may be decreased to zero percent (0%) at any time during a
Purchase Period.  Payroll deductions shall recommence at the rate provided in
such participant's subscription agreement at the beginning of the first Purchase
Period which is scheduled to end in the following calendar year, unless
terminated by the participant as provided in Section 10 hereof.

          (e) At the time the option is exercised, in whole or in part, or at
the time some or all of the Company's Common Stock issued under the Plan is
disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock.  At any time,
the Company may, but shall not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee.

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

                                      -4-
<PAGE>

shares of the Company's Common Stock determined by dividing such Employee's
payroll deductions accumulated prior to such Exercise Date and retained in the
Participant's account as of the Exercise Date by the applicable Purchase Price;
provided that in no event shall an Employee be permitted to purchase during each
Purchase Period more than 5,000 shares of the Company's Common Stock (subject
to any adjustment pursuant to Section 19), and provided further that such
purchase shall be subject to the limitations set forth in Sections 3(b) and 12
hereof. The Board may, for future Offering Periods, increase or decrease, in its
absolute discretion, the maximum number of shares of the Company's Common Stock
an Employee may purchase during each Purchase Period of such Offering Period.
Exercise of the option shall occur as provided in Section 8 hereof, unless the
participant has withdrawn pursuant to Section 10 hereof. The option shall expire
on the last day of the Offering Period.

     8.   Exercise of Option.
          ------------------

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

          (b) If the Board determines that, on a given Exercise Date, the number
of shares with respect to which options are to be exercised may exceed (i) the
number of shares of Common Stock that were available for sale under the Plan on
the Enrollment Date of the applicable Offering Period, or (ii) the number of
shares available for sale under the Plan on such Exercise Date, the Board may in
its sole discretion (x) provide that the Company shall make a pro rata
allocation of the shares of Common Stock available for purchase on such
Enrollment Date or Exercise Date, as applicable, in as uniform a manner as shall
be practicable and as it shall determine in its sole discretion to be equitable
among all participants exercising options to purchase Common Stock on such
Exercise Date, and continue all Offering Periods then in effect, or (y) provide
that the Company shall make a pro rata allocation of the shares available for
purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform
a manner as shall be practicable and as it shall determine in its sole
discretion to be equitable among all participants exercising options to purchase
Common Stock on such Exercise Date, and terminate any or all Offering Periods
then in effect pursuant to Section 20 hereof.  The Company may make pro rata
allocation of the shares available on the Enrollment Date of any applicable
Offering Period pursuant to the preceding sentence, notwithstanding any
authorization of additional shares for issuance under the Plan by the Company's
shareholders subsequent to such Enrollment Date.

     9.   Delivery.  As promptly as practicable after each Exercise Date on
          --------
which a purchase of shares occurs, the Company shall arrange the delivery to
each participant, as appropriate, of the shares purchased upon exercise of his
or her option.

     10.  Withdrawal.
          ----------

          (a) A participant may withdraw all but not less than all the payroll
deductions credited to his or her account and not yet used to exercise his or
her option under the Plan at any time by giving written notice to the Company in
the form of Exhibit B to this Plan.  All of the participant's payroll deductions
credited to his or her account shall be paid to such participant promptly after
receipt of notice of withdrawal and such participant's option for the Offering
Period shall be automatically terminated, and no further payroll deductions for
the purchase of shares shall be made for such Offering Period.  If a participant
withdraws from an Offering Period, payroll deductions shall not resume at the
beginning of the succeeding Offering Period unless the participant delivers to
the Company a new subscription agreement.

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

     11.  Termination of Employment.
          -------------------------

          Upon a participant's ceasing to be an Employee, for any reason, he or
she shall be deemed to have elected to withdraw from the Plan and the payroll
deductions credited to such participant's account during the Offering Period but
not yet used to exercise the option shall be returned to such participant or, in
the case of his or her death, to the person or persons entitled thereto under
Section 15 hereof, and such participant's option shall be automatically
terminated.  The preceding sentence notwithstanding, a participant who receives
payment in lieu of notice of termination of employment shall be treated as
continuing to be an Employee for the participant's customary number of hours per
week of employment during the period in which the participant is subject to such
payment in lieu of notice.

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

     13.  Stock.
          -----

          (a) Subject to adjustment upon changes in capitalization of the
Company as provided in Section 19 hereof, the maximum number of shares of the
Company's Common Stock which shall be made available for sale under the Plan
shall be 500,000 shares, plus an annual increase to be added on the first day of
the Company's fiscal year beginning in 2000 equal to the lesser of (i) 350,000
shares, (ii) 1% of the outstanding shares on such date or (iii) a lesser amount
determined by the Board.

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

                                      -6-
<PAGE>

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

     14.  Administration.  The Plan shall be administered by the Board or a
          --------------
committee of members of the Board appointed by the Board.  The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan.  Every finding, decision
and determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

     15.  Designation of Beneficiary.
          --------------------------

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

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

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

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

     18.  Reports.  Individual accounts shall be maintained for each participant
          -------
in the Plan.  Statements of account shall be given to participating Employees at
least annually, which statements shall set forth the amounts of payroll
deductions, the Purchase Price, the number of shares purchased and the remaining
cash balance, if any.

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

          (a) Changes in Capitalization.  Subject to any required action by the
              -------------------------
shareholders of the Company, the Reserves, the maximum number of shares each
participant may purchase each Purchase Period (pursuant to Section 7), as well
as the price per share and the number of shares of Common Stock covered by each
option under the Plan which has not yet been exercised shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration".  Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an option.

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

          (c) Merger or Asset Sale.  In the event of a proposed sale of all or
              --------------------
substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, each outstanding option shall be assumed or an
equivalent option substituted by the successor corporation or a Parent or
Subsidiary of the successor corporation.  In the event that the successor
corporation refuses to assume or substitute for the option, any Purchase Periods
then in progress shall be shortened by setting a new Exercise Date (the "New
Exercise Date") and any Offering Periods then in progress shall end on the New
Exercise Date.  The New Exercise Date shall be before the date of the Company's
proposed sale or merger.  The Board shall notify each participant in writing, at
least ten (10) business days prior to the New Exercise Date, that the Exercise
Date for the participant's option has been changed to the New Exercise Date and
that the participant's option shall be exercised automatically on the New
Exercise Date, unless prior to such date the participant has withdrawn from the
Offering Period as provided in Section 10 hereof.

     20.  Amendment or Termination.
          ------------------------

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

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

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

               (i) altering the Purchase Price for any Offering Period including
an Offering Period underway at the time of the change in Purchase Price;

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

               (iii)  allocating shares.

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

     21.  Notices.  All notices or other communications by a participant to the
          -------
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

     22.  Conditions Upon Issuance of Shares.  Shares shall not be issued with
          ----------------------------------
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

          As a condition to the exercise of an option, the Company may require
the person exercising such option to represent and warrant at the time of any
such exercise that the shares are being purchased only for investment and
without any present intention to sell or distribute such shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned applicable provisions of law.

     23.  Term of Plan.  The Plan shall become effective upon the earlier to
          ------------
occur of its adoption by the Board of Directors or its approval by the
shareholders of the Company.  It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 20 hereof.

     24.  Automatic Transfer to Low Price Offering Period.  To the extent
          -----------------------------------------------
permitted by any applicable laws, regulations, or stock exchange rules if the
Fair Market Value of the Common Stock on any Exercise Date in an Offering Period
is lower than the Fair Market Value of the Common Stock on the Enrollment Date
of such Offering Period, then all participants in such Offering Period shall be
automatically withdrawn from such Offering Period immediately after the exercise
of their option on such Exercise Date and automatically re-enrolled in the
immediately following Offering Period as of the first day thereof.

                       1999 EMPLOYEE STOCK PURCHASE PLAN

                             SUBSCRIPTION AGREEMENT



     _____ Original Application                    Enrollment Date: ___________
     _____ Change in Payroll Deduction Rate
     _____ Change of Beneficiary(ies)

1.   ___________ hereby elects to participate in the E-Stamp Corporation 1999
     Employee Stock Purchase Plan (the "Employee Stock Purchase Plan") and
     subscribes to purchase shares of the Company's Common Stock in accordance
     with this Subscription Agreement and the Employee Stock Purchase Plan.

2.   I hereby authorize payroll deductions from each paycheck in the amount of
     ____% of my Compensation on each payday (from 1 to 15%) during the Offering
     Period in accordance with the Employee Stock Purchase Plan.  (Please note
     that no fractional percentages are permitted.)

3.   I understand that said payroll deductions shall be accumulated for the
     purchase of shares of Common Stock at the applicable Purchase Price
     determined in accordance with the Employee Stock Purchase Plan.  I
     understand that if I do not withdraw from an Offering Period, any
     accumulated payroll deductions will be used to automatically exercise my
     option.

4.   I have received a copy of the complete Employee Stock Purchase Plan.  I
     understand that my participation in the Employee Stock Purchase Plan is in
     all respects subject to the terms of the Plan.  I understand that my
     ability to exercise the option under this Subscription Agreement is subject
     to shareholder approval of the Employee Stock Purchase Plan.

5.   Shares purchased for me under the Employee Stock Purchase Plan should be
     issued in the name(s) of (Employee or Employee and Spouse only).

6.   I understand that if I dispose of any shares received by me pursuant to the
     Plan within 2 years after the Enrollment Date (the first day of the
     Offering Period during which I purchased such shares) or one year after the
     Exercise Date, I will be treated for federal income tax purposes as having
     received ordinary income at the time of such disposition in an amount equal
     to the excess of the fair market value of the shares at the time such
     shares were purchased by me over the price which I paid for the shares. I
                                                                             -
     hereby agree to notify the Company in writing within 30 days after the date
     ---------------------------------------------------------------------------
     of any disposition of my shares and I will make adequate provision for
     ----------------------------------------------------------------------
     Federal, state or other tax withholding obligations, if any, which arise
     ------------------------------------------------------------------------
     upon the
     --------
<PAGE>

     disposition of the Common Stock.  The Company may, but will not be
     -------------------------------
     obligated to, withhold from my compensation the amount necessary to meet
     any applicable withholding obligation including any withholding necessary
     to make available to the Company any tax deductions or benefits
     attributable to sale or early disposition of Common Stock by me.  If I
     dispose of such shares at any time after the expiration of the 2-year and
     1-year holding periods, I understand that I will be treated for federal
     income tax purposes as having received income only at the time of such
     disposition, and that such income will be taxed as ordinary income only to
     the extent of an amount equal to the lesser of (1) the excess of the fair
     market value of the shares at the time of such disposition over the
     purchase price which I paid for the shares, or (2) 15% of the fair market
     value of the shares on the first day of the Offering Period.  The remainder
     of the gain, if any, recognized on such disposition will be taxed as
     capital gain.

7.   I hereby agree to be bound by the terms of the Employee Stock Purchase
     Plan.  The effectiveness of this Subscription Agreement is dependent upon
     my eligibility to participate in the Employee Stock Purchase Plan.

8.   In the event of my death, I hereby designate the following as my
     beneficiary(ies) to receive all payments and shares due me under the
     Employee Stock Purchase Plan:



     NAME:  (Please print)          _____________________________________

        4.  Administration and Grants of Options under the Plan.
            ---------------------------------------------------

            (a)  Procedure for Grants.  All grants of Options to Outside
                 --------------------
Director under this Plan shall be automatic in accordance with the following
provisions:

                 (i)   Each Outside Director, who first becomes an Outside
Director after the effective date of this Plan, shall be automatically granted
an Option to purchase 40,000 Shares (the "First Option") on the date on which
such person first becomes an Outside Director, whether through election by the
stockholders of the Company or appointment by the Board to fill a vacancy;
provided, however, that an Inside Director who ceases to be an Inside Director
but who remains a Director shall not receive a First Option.

                 (ii)  Each Outside Director shall be automatically granted an
Option to purchase 2,500 Shares (a "Subsequent Option") on the date of each of
annual meeting of the stockholders held after the effective date of this Plan,
provided he or she is then an Outside Director and if as of such date, he or
she shall have served on the Board for at least the preceding six (6) months.

                 (iii) Notwithstanding the provisions of subsections (i) and
(ii) hereof, any exercise of an Option granted before the Company has obtained
stockholder approval of the Plan in accordance with Section 16 hereof shall be
conditioned upon obtaining such stockholder approval of the Plan in accordance
with Section 16 hereof.

                 (iv)  The terms of each First Option granted under this
Section 4 shall be as follows:

                       (A)  the term of the First Option shall be ten (10)
years.

                       (B)  the First Option shall be exercisable only while
the Outside Director remains a Director of the Company, except as set forth in
Sections 8 and 10 hereof.

                       (C)  the exercise price per Share shall be 100% of the
Fair Market Value per Share on the date of grant of the First Option.

                       (D)  subject to Section 10 hereof, the First Option
shall become exercisable as to one-forty-eighth (1/48) of the Shares subject to
the First Option on each monthly anniversary of its date of grant, provided
that the Optionee continues to serve as a Director on such dates.

                       (E)  the First Option shall be a nonstatutory stock
option.

                                      -3-
<PAGE>

                 (v)   The terms of a Subsequent Option granted hereunder shall
be as follows:

                       (A)  the term of the Subsequent Option shall be ten
(10) years.

                       (B)  the Subsequent Option shall be exercisable only
while the Outside Director remains a Director of the Company, except as set
forth in Sections 8 and 10 hereof.

                       (C)  the exercise price per Share shall be 100% of the
Fair Market Value per Share on the date of grant of the Subsequent Option.

                       (D)  subject to Section 10 hereof, the Subsequent
Option shall become exercisable as to one-twelfth (1/12) of the Shares subject
to the Subsequent Option on each monthly anniversary of its date of grant,
provided that the Optionee continues to serve as a Director on such dates,

                       (E)  the Subsequent Option shall be a nonstatutory
stock option.

                 (vi)  In the event that any Option granted under the Plan
would cause the number of Shares subject to outstanding Options plus the
number of Shares previously purchased under Options to exceed the Pool, then
the remaining Shares available for Option grant shall be granted under Options
to the Outside Directors on a pro rata basis. No further grants shall be made
until such time, if any, as additional Shares become available for grant under
the Plan through action of the Board or the stockholders to increase the
number of Shares which may be issued under the Plan or through cancellation or
expiration of Options previously granted hereunder.

        5.  Eligibility.  Options may be granted only to Outside Directors.
            -----------
All Options shall be automatically granted in accordance with the terms set
forth in Section 4 hereof.

            The Plan shall not confer upon any Optionee any right with respect
to continuation of service as a Director or nomination to serve as a Director,
nor shall it interfere in any way with any rights which the Director or the
Company may have to terminate the Director's relationship with the Company at
any time.

        6.  Term of Plan.  The Plan was adopted by the Board in August 1999,
            ------------
and is subject to stockholder approval as described in Section 16 of the Plan.
The Plan shall become effective immediately upon the effective date of the
initial public offering of the Company's common stock pursuant to a
registration statement filed under Section 12 of the Exchange Act. The Plan
shall continue in effect for a term of ten (10) years unless sooner terminated
under Section 11 of the Plan.

        7.  Form of Consideration.  The consideration to be paid for the Shares
            ---------------------
to be issued upon exercise of an Option, including the method of payment, shall
consist of (i) cash, (ii) check, (iii) other shares which (x) in the case of
Shares acquired upon exercise of an option, have been owned by the Optionee for
more than six (6) months on the date of surrender, and (y) have a Fair

                                      -4-
<PAGE>

Market Value on the date of surrender equal to the aggregate exercise price of
the Shares as to which said Option shall be exercised, (iv) consideration
received by the Company under a cashless exercise program implemented by the
Company in connection with the Plan, or (v) any combination of the foregoing
methods of payment.

        8.  Exercise of Option.
            ------------------

            (a)  Procedure for Exercise; Rights as a Stockholder. Any Option
                 -----------------------------------------------
granted hereunder shall be exercisable at such times as are set forth in
Section 4 hereof; provided, however, that no Options shall be exercisable
until stockholder approval of the Plan in accordance with Section 16 hereof
has been obtained.

                 An Option may not be exercised for a fraction of a Share.

                 An Option shall be deemed to be exercised when notice of such
exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company. Full payment may consist of any consideration and method of payment
allowable under Section 7 of the Plan. Until the issuance (as evidenced by the
appropriate entry on the books of the Company or of a duly authorized transfer
agent of the Company) of the stock certificate evidencing such Shares, no
right to vote or receive dividends or any other rights as a stockholder shall
exist with respect to the Optioned Stock, notwithstanding the exercise of the
Option. A share certificate for the number of Shares so acquired shall be
issued to the Optionee as soon as practicable after exercise of the Option. No
adjustment shall be made for a dividend or other right for which the record
date is prior to the date the stock certificate is issued, except as provided
in Section 10 of the Plan.

                 Exercise of an Option in any manner shall result in a
decrease in the number of Shares which thereafter may be available, both for
purposes of the Plan and for sale under the Option, by the number of Shares as
to which the Option is exercised.

            (b)  Termination of Continuous Status as a Director.  Subject to
                 ----------------------------------------------
Section 10 hereof, in the event an Optionee's status as a Director terminates
(other than upon the Optionee's death or Disability), the Optionee may
exercise his or her Option, but only within three (3) months following the
date of such termination, and only to the extent that the Optionee was
entitled to exercise it on the date of such termination (but in no event later
than the expiration of its ten (10) year term). To the extent that the
Optionee was not entitled to exercise an Option on the date of such
termination and to the extent that the Optionee does not exercise such Option
(to the extent otherwise so entitled) within the time specified herein, the
Option shall terminate.

            (c)  Disability of Optionee.  In the event Optionee's status as a
                 ----------------------
Director terminates as a result of Disability, the Optionee may exercise his
or her Option, but only within twelve (12) months following the date of such
termination, and only to the extent that the Optionee was entitled

                                      -5-
<PAGE>

to exercise it on the date of such termination (but in no event later than the
expiration of its ten (10)-year term). To the extent that the Optionee was not
entitled to exercise an Option on the date of termination, or if he or she
does not exercise such Option (to the extent otherwise so entitled) within the
time specified herein, the Option shall terminate.

            (d)  Death of Optionee.  In the event of an Optionee's death, the
                 -----------------
Optionee's estate or a person who acquired the right to exercise the Option by
bequest or inheritance may exercise the Option, but only within twelve (12)
months following the date of death, and only to the extent that the Optionee
was entitled to exercise it on the date of death (but in no event later than
the expiration of its ten (10) year term). To the extent that the Optionee was
not entitled to exercise an Option on the date of death, and to the extent
that the Optionee's estate or a person who acquired the right to exercise such
Option does not exercise such Option (to the extent otherwise so entitled)
within the time specified herein, the Option shall terminate.

        9.  Non-Transferability of Options.  The Option may not be sold,
            ------------------------------
pledged, assigned, hypothecated, transferred, or disposed of in any manner
other than by will or by the laws of descent or distribution and may be
exercised, during the lifetime of the Optionee, only by the Optionee.

        10. Adjustments Upon Changes in Capitalization, Dissolution, Merger or
            ------------------------------------------------------------------
Asset Sale.
- ----------

            (a)  Changes in Capitalization.  Subject to any required action by
                 -------------------------
the stockholders of the Company, the number of Shares covered by each
outstanding Option, the number of Shares which have been authorized for
issuance under the Plan but as to which no Options have yet been granted or
which have been returned to the Plan upon cancellation or expiration of an
Option, as well as the price per Share covered by each such outstanding
Option, and the number of Shares issuable pursuant to the automatic grant
provisions of Section 4 hereof shall be proportionately adjusted for any
increase or decrease in the number of issued Shares resulting from a stock
split, reverse stock split, stock dividend, combination or reclassification of
the Common Stock, or any other increase or decrease in the number of issued
Shares effected without receipt of consideration by the Company; provided,
however, that conversion of any convertible securities of the Company shall
not be deemed to have been "effected without receipt of consideration." Except
as expressly provided herein, no issuance by the Company of shares of stock of
any class, or securities convertible into shares of stock of any class, shall
affect, and no adjustment by reason thereof shall be made with respect to, the
number or price of Shares subject to an Option.

            (b)  Dissolution or Liquidation.  In the event of the proposed
                 --------------------------
dissolution or liquidation of the Company, to the extent that an Option has
not been previously exercised, it shall terminate immediately prior to the
consummation of such proposed action.

            (c)  Merger or Asset Sale.  In the event of a merger of the Company
                 --------------------
with or into another corporation or the sale of substantially all of the
assets of the Company, outstanding Options may be assumed or equivalent
options may be substituted by the successor corporation or a Parent or
Subsidiary thereof (the "Successor Corporation"). If an Option is assumed or
substituted for, the

                                      -6-
<PAGE>

Option or equivalent option shall continue to be exercisable as provided in
Section 4 hereof for so long as the Optionee serves as a Director or a
director of the Successor Corporation. Following such assumption or
substitution, if the Optionee's status as a Director or director of the
Successor Corporation, as applicable, is terminated other than upon a
voluntary resignation by the Optionee, the Option or option shall become fully
exercisable, including as to Shares for which it would not otherwise be
exercisable. Thereafter, the Option or option shall remain exercisable in
accordance with Sections 8(b) through (d) above.

            If the Successor Corporation does not assume an outstanding Option
or substitute for it an equivalent option, the Option shall become fully
vested and exercisable, including as to Shares for which it would not
otherwise be exercisable. In such event the Board shall notify the Optionee
that the Option shall be fully exercisable for a period of thirty (30) days
from the date of such notice, and upon the expiration of such period the
Option shall terminate.

            For the purposes of this Section 10(c), an Option shall be
considered assumed if, following the merger or sale of assets, the Option
confers the right to purchase or receive, for each Share of Optioned Stock
subject to the Option immediately prior to the merger or sale of assets, the
consideration (whether stock, cash, or other securities or property) received
in the merger or sale of assets by holders of Common Stock for each Share held
on the effective date of the transaction (and if holders were offered a choice
of consideration, the type of consideration chosen by the holders of a
majority of the outstanding Shares). If such consideration received in the
merger or sale of assets is not solely common stock of the Successor
Corporation or its Parent, the Administrator may, with the consent of the
Successor Corporation, provide for the consideration to be received upon the
exercise of the Option, for each Share of Optioned Stock subject to the
Option, to be solely common stock of the Successor Corporation or its Parent
equal in fair market value to the per share consideration received by holders
of Common Stock in the merger or sale of assets.

        11. Amendment and Termination of the Plan.
            -------------------------------------

            (a)  Amendment and Termination.  The Board may at any time amend,
                  -------------------------
alter, suspend, or discontinue the Plan, but no amendment, alteration,
suspension, or discontinuation shall be made which would impair the rights of
any Optionee under any grant theretofore made, without his or her consent. In
addition, to the extent necessary and desirable to comply with any applicable
law, regulation or stock exchange rule, the Company shall obtain stockholder
approval of any Plan amendment in such a manner and to such a degree as
required.

            (b)  Effect of Amendment or Termination.  Any such amendment or
                 ----------------------------------
termination of the Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated.

        12. Time of Granting Options.  The date of grant of an Option shall,
            ------------------------
for all purposes, be the date determined in accordance with Section 4 hereof.

                                      -7-
<PAGE>

        13. Conditions Upon Issuance of Shares.  Shares shall not be issued
            ----------------------------------
pursuant to the exercise of an Option unless the exercise of such Option and
the issuance and delivery of such Shares pursuant thereto shall comply with
all relevant provisions of law, including, without limitation, the Securities
Act of 1933, as amended, the Exchange Act, the rules and regulations
promulgated thereunder, state securities laws, and the requirements of any
stock exchange upon which the Shares may then be listed, and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

            As a condition to the exercise of an Option, the Company may require
the person exercising such Option to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares, if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law.

            Inability of the Company to obtain authority from any regulatory
body having jurisdiction, which authority is deemed by the Company's counsel
to be necessary to the lawful issuance and sale of any Shares hereunder, shall
relieve the Company of any liability in respect of the failure to issue or
sell such Shares as to which such requisite authority shall not have been
obtained.

        14. Reservation of Shares.  The Company, during the term of this Plan,
            ---------------------
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

        15. Option Agreement.  Options shall be evidenced by written option
            ----------------
agreements in such form as the Board shall approve.

        16. Stockholder Approval.  The Plan shall be subject to approval by the
            --------------------
stockholders of the Company within twelve (12) months after the date the Plan is
adopted.  Such stockholder approval shall be obtained in the degree and manner
required under applicable state and federal law and any stock exchange rules.

                              E-STAMP CORPORATION

                           DIRECTOR OPTION AGREEMENT



          E-Stamp Corporation, (the "Company"), has granted to _________ (the
"Optionee"), an option to purchase a total of [________(____)] shares of the
Company's Common Stock (the "Optioned Stock"), at the price determined as
provided herein, and in all respects subject to the terms, definitions and
provisions of the Company's 1999 Director Option Plan (the "Plan") adopted by
the Company which is incorporated herein by reference. The terms defined in the
Plan shall have the same defined meanings herein.

          1.  Nature of the Option.  This Option is a nonstatutory option and is
              --------------------
not intended to qualify for any special tax benefits to the Optionee.

          2.  Exercise Price.  The exercise price is $_______ for each share of
              --------------
Common Stock.

          3.  Exercise of Option.  This Option shall be exercisable during its
              ------------------
term in accordance with the provisions of Section 8 of the Plan as follows:

              (a)  Right to Exercise.
                   -----------------

                   (i) This Option shall be exercisable for one hundred percent
(100%) the Optioned Stock on the date of grant; provided, however, that in no
event shall any Option be exercisable prior to the date the stockholders of the
Company approve the Plan.

                   (ii) This Option may not be exercised for a fraction of a
share.

                   (iii)  In the event of Optionee's death, disability or other
termination of service as a Director, the exercisability of the Option is
governed by Section 8 of the Plan.

              (b)  Method of Exercise.  This Option shall be exercisable by
                   ------------------
written notice which shall state the election to exercise the Option and the
number of Shares in respect of which the Option is being exercised. Such written
notice, in the form attached hereto as Exhibit A, shall be signed by the
Optionee and shall be delivered in person or by certified mail to the Secretary
of the Company. The written notice shall be accompanied by payment of the
exercise price.

          4.  Method of Payment.  Payment of the exercise price shall be by any
              -----------------
of the following, or a combination thereof, at the election of the Optionee:

              (a)  cash;

              (b)  check; or

<PAGE>

              (c) surrender of other shares which (x) in the case of Shares
acquired upon exercise of an Option, have been owned by the Optionee for more
than six (6) months on the date of surrender, and (y) have a Fair Market Value
on the date of surrender equal to the aggregate exercise price of the Shares as
to which said Option shall be exercised; or

              (d) delivery of a properly executed exercise notice together with
such other documentation as the Company and the broker, if applicable, shall
require to effect an exercise of the Option and delivery to the Company of the
sale or loan proceeds required to pay the exercise price.

          5.  Restrictions on Exercise.  This Option may not be exercised if the
              ------------------------
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulations, or if such issuance
would not comply with the requirements of any stock exchange upon which the
Shares may then be listed.  As a condition to the exercise of this Option, the
Company may require Optionee to make any representation and warranty to the
Company as may be required by any applicable law or regulation.

          6.  Non-Transferability of Option.  This Option may not be transferred
              -----------------------------
in any manner otherwise than by will or by the laws of descent or distribution
and may be exercised during the lifetime of Optionee only by the Optionee.  The
terms of this Option shall be binding upon the executors, administrators, heirs,
successors and assigns of the Optionee.

          7.  Term of Option.  This Option may not be exercised more than ten
              --------------
(10) years from the date of grant of this Option, and may be exercised during
such period only in accordance with the Plan and the terms of this Option.

          8.  Taxation Upon Exercise of Option. Optionee understands that, upon
              --------------------------------
exercise of this Option, he or she will recognize income for tax purposes in an
amount equal to the excess of the then Fair Market Value of the Shares purchased
over the exercise price paid for such Shares. Since the Optionee is subject to
Section 16(b) of the Securities Exchange Act of 1934, as amended, under certain
limited circumstances the measurement and timing of such income (and the
commencement of any capital gain holding period) may be deferred, and the
Optionee is advised to contact a tax advisor concerning the application of
Section 83 in general and the availability a Section 83(b) election in
particular in connection with the exercise of the Option. Upon a resale of such
Shares by the Optionee, any difference between the sale price and the Fair
Market Value of the Shares on the date of exercise of the Option, to the extent
not included in income as described above, will be treated as capital gain or
loss.

determined by the Committee in its sole discretion and set forth in the Stock
Option Agreement; provided, however, in the case of an ISO granted to an
                  --------  -------
Optionee, the Exercise Price shall not be less than 100% of the Fair Market
Value of the Shares subject to such option on the Date of Grant (or 110% in the

              -----------------
Option shall be made in cash, by certified check, or if authorized by the
Committee, by delivery of other Shares having a Fair Market Value on the date of
delivery equal to the aggregate exercise price of the Shares as to which said
Option is being exercised, or by any combination of such methods of payment or
by any other method of payment as may be permitted under applicable law and
authorized by the Committee.

     (d)  Exercise of Option.
          ------------------

         (i)  Procedure for Exercise; Rights of Stockholder.  Any Option granted
              ---------------------------------------------
hereunder shall be exercisable at such times and under such conditions as shall
be determined by the Committee, including without limitation performance
criteria with respect to the Company and/or the Optionee, and in accordance with
the terms of this Plan. An Option may not be exercised for a fraction of a
Share.

     An Option shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the Stock
Option Agreement by the Optionee entitled to exercise the Option and full
payment for the Shares and any withholding and other applicable taxes with
respect to which the Option is exercised has been received by the Company.  Full
payment may, as authorized by the Committee, consist of any form of
consideration and method of payment allowable under Section 6(c)(ii) of this
Plan.  Upon the receipt of notice of exercise and full payment for the Shares
and taxes, the Shares shall be deemed to have been issued and the Optionee shall
be entitled to receive such Shares and shall be a stockholder with respect to
such Shares, and the Shares shall be considered fully paid and nonassessable.
No adjustment will be made for a dividend or other right for which the record
date is prior to the date on which the stock certificate is issued, except as
provided in Section 9 of this Plan.

     Each exercise of an Option shall reduce, by an equal number, the total
number of Shares that may thereafter be purchased under such Option.

earlier of the date (i) the Option held by the Optionee expires, or (ii) (y) in
the case of an ISO, ninety (90) days, and (z) in the case of a Nonstatutory
Option, six (6) months, after the date such Optionee ceases to be an Employee or
a Consultant (or in each case, such shorter period as may be provided in the
Stock Option Agreement), exercise the Option to the extent that the Optionee was
entitled to exercise it on such date, unless the Committee terminates or further
extends such period in its sole discretion.  To the extent that the Optionee was
not entitled to exercise an Option on such date, or if the Optionee does not
exercise it within the time specified herein, such Option shall terminate.  The
Committee shall have the authority (i) to determine the date an Optionee ceases
to be an Employee or a Consultant and (ii) to shorten or terminate the exercise
periods provided above in the event the Optionee resigns and/or ceases for
"cause" to be an Employee or a Consultant.

         (iii)   Permanent and Total Disability.   Notwithstanding the
                 ------------------------------
provisions of Section 6(d)(ii) above, in the event an Optionee is unable to
continue to perform Services for the Company or any of its Subsidiaries as a
result of such Optionee's Permanent and Total Disability, (and, for ISOs, at the
time such Permanent and Total Disability begins, the Optionee was an Employee
and had been an Employee since the Date of Grant), such Optionee may exercise an
Option in whole or in part to the extent that the Optionee was entitled to
exercise it on such date, but only until the earlier of the date (i) the Option
held by the Optionee expires, or (ii) twelve (12) months from the date of
termination of Services due to such Permanent and Total Disability.  To the
extent the Optionee is not entitled to exercise an Option on such date or if the
Optionee does not exercise it within the time specified herein, such Option

discretion.

         (iv)  Death of an Optionee.  Upon the death of an Optionee, any Option
               --------------------
held by an Optionee shall terminate and be of no further effect; provided,

an Optionee's death occurs during the term of an Option held by such Optionee
and, at the time of death, the Optionee was an Employee or Consultant (and, for
ISOs, at the time of death, the Optionee was an Employee and had been an
Employee since the Date of Grant), the Option may be exercised in whole or in
part to the extent that the Optionee was entitled to exercise it on such date,
but only until the earlier of the date (i) the Option held by the Optionee
expires, or (ii) twelve (12) months from the date of the Optionee's death, by
the Optionee's estate or by a person who acquired the right to exercise the
Option by bequest or inheritance.  To the extent the Option is not entitled to
be exercised on such date or if the Option is not exercised within the time
specified herein, such Option shall terminate, unless the Committee further
extends such period in its sole discretion.

         (v)   Return of Proceeds.
               ------------------

          (a)  The Committee, in its discretion, may include as a term of any
Optionee's Stock Option Agreement a provision that, if within one year after
ceasing to be an Employee or Consultant (whether voluntarily or involuntarily),
an Optionee shall, directly or indirectly, engage in an activity that competes
with the business of the Company or a Subsidiary as conducted at the time the
Optionee ceased to be an Employee or Consultant (as determined by the Board of
Directors in its sole discretion and good faith) and such Optionee had exercised
Options within six months of the date the Optionee ceased to be an Employee or
Consultant, the Optionee shall be required to remit to the Company in good funds
within 5 business days of receipt of written demand therefore an amount equal to
(i) the excess of (A) the Fair Market Value per share of Common Stock on the
date of exercise of such Option(s) less (B) the aggregate option exercise price
for such number of shares of Common Stock multiplied by (ii) the number of
shares with respect to which the Options were exercised (the "Proceeds").

          (b)   The Committee, in its discretion, may include as a term of any
Optionee's Stock Option Agreement a provision requiring the remittance by an
Optionee to the Company in good funds within 5 business days of receipt of
written demand therefore of Proceeds by an Optionee that has exercised Options
within six months of the date the Optionee ceased to be an Employee or
Consultant (whether voluntarily or involuntarily).  The Committee shall have the
authority in its discretion to include such other conditions and/or terms in an
Optionee's Stock Option Agreement that it deems appropriate or desirable in
furtherance of the foregoing provisions.
<PAGE>

     (e) Non-Transferability of Options.  No Option granted under this Plan may
         ------------------------------
be sold, pledged, assigned, hypothecated, transferred or disposed of in any
manner other than by will or by the laws of descent and distribution or pursuant
to a qualified domestic relations order as defined by the Code or Title I of the
Employee Retirement Income Security Act, or the rules thereunder, and no Option
granted under this Plan is assignable by operation of law or subject to
execution, attachment or similar process.  Any Option granted under this Plan
can only be exercised during the Optionee's lifetime by such Optionee unless
exercised pursuant to Section 6(d)(iv).  Any attempted sale, pledge, assignment,
hypothecation or other transfer of the Option contrary to the provisions hereof
and the levy of any execution, attachment or similar process upon the Option
shall be null and void and without force or effect.  No transfer of the Option
by will or by the laws of descent and distribution shall be effective to bind
the Company unless the Company shall have been furnished written notice thereof
and an authenticated copy of the will and/or such other evidence as the
Committee may deem necessary to establish the validity of the transfer and the
acceptance by the transferee or transferees of the terms and conditions of the
Option.  The terms of any Option transferred by will or by the laws of descent
and distribution shall be binding upon the executors, administrators, heirs and
successors of Optionee.

     (f) Time of Granting Options.  Any Option granted hereunder shall be deemed
         ------------------------
to be granted on the Date of Grant.  Written notice of the Committee's
determination to grant an Option to an Employee, evidenced by a Stock Option
Agreement, dated as of the Date of Grant, shall be given to such Employee within
a reasonable time after the Date of Grant.

     (g) Modification, Extension and Renewal of Options. Within the limitations
         ----------------------------------------------
of this Plan, the Committee may modify, extend or renew outstanding Options or
may accept the cancellation of outstanding Options (to the extent not previously
exercised) for the granting of new Options in substitution therefor.  The
foregoing notwithstanding, no modification of an Option shall, without the
consent of the Optionee, alter or impair the Optionee's rights or obligations
under such Option.

     (h) Restrictions on Transfer of Shares.  Any Shares issued upon exercise of
         ----------------------------------
an Option shall be subject to such rights of repurchase and other transfer
restrictions as the Committee may determine in its sole discretion.  Such
restrictions shall be set forth in the applicable Stock Option Agreement.

     (i) Special Limitation on ISOs.  To the extent that the aggregate Fair
         --------------------------
Market Value (determined on the Date of Grant) of the Shares with respect to
which ISOs are exercisable for the first time by an individual during any
calendar year under this Plan, and under all other plans maintained by the
Company, exceeds $100,000, such Options shall be treated as Options that are not
ISOs.

     (j) Leaves of Absence.  Leaves of absence approved by the Committee which
         ------------------
conform to the policies of the Company shall not be considered termination of
employment if the employer-employee relationship as defined under the Code or
the regulations promulgated thereunder otherwise exists.

     (k) Limitation on Grants.  Notwithstanding any other provision contained in
         --------------------
this Plan, no Employee may receive in any one calendar year Options under this
Plan to acquire and rights to purchase more than 150,000 Shares.

     (l) Early Exercise.  In the Committee's sole and absolute discretion, an
         --------------
Option may include a provision whereby the Optionee may elect at anytime while
an Employee or Consultant to exercise the Option as to any part or all of the
Shares subject to the Option prior to the full vesting of the Option.  Any
unvested Shares so purchased shall be subject to a repurchase right in favor of
the Company, with the repurchase price to be equal to the original purchase
price of the Shares, or to any other restriction the Committee determines to be
appropriate, provided however, that (i) the right to repurchase at the original
purchase price shall lapse at a rate equal to the remaining portion of the
original vesting schedule of the Shares so purchased, (ii) such repurchase right
shall be exercisable by the Company within (A) the ninety (90) day period
following the termination of employment or relationship as a Consultant for any
reason whatsoever, or (B) such longer period as may be agreed to by the Company
and the Optionee (for example, for purposes of satisfying the requirements of
Section 1202(c)(3) of the Code (regarding "qualified small business stock")),
and (iii) such repurchase right shall be exercisable for cash or cancellation of
purchase money indebtedness for the Shares.  Should the right of repurchase be
assigned by the Company, the assignee shall pay the Company cash equal to the
<PAGE>

difference between the original purchase price and stock's fair market value if
the original purchase price is less than the stock's fair market value.

                                   SECTION 7
                               RESTRICTED STOCK
                               ----------------

     (a) Authority to Grant Restricted Stock.  The Committee shall have the
         -----------------------------------
authority to grant Shares to Participants that are subject to certain terms,
conditions, and restrictions (the "Restricted Stock").  The Restricted Stock may
                                   ----------------
be granted by the Committee either separately or in combination with Options.
The terms, conditions and restrictions of the Restricted Stock shall be
determined from time to time by the Committee without limitation, except as
otherwise provided in this Plan; provided, however, that each grant of
                                 --------  -------
Restricted Stock to an Employee shall require the Employee to remain an Employee
of the Company or any of its Subsidiaries for at least six (6) months from the
Date of Grant.  The granting, vesting, and issuing of the Restricted Stock shall
also be subject to the following provisions:

         (i)  Nature of Grant.  Restricted Stock shall be granted to
              ---------------
Participants for Services rendered and at no additional cost to Participant;
provided, however, that the value of the Services performed must, in the opinion
- --------  -------
of the Committee, equal or exceed the par value of the Restricted Stock to be
granted to the Participant.

         (ii)  Restricted Stock Account.  The Company shall establish a
               ------------------------
restricted stock account (the "Restricted Stock Account") for each Participant
                               ------------------------
to whom Restricted Stock is granted, and such Restricted Stock shall be credited
to such account.  No certificates will be issued to the Participant with respect
to the Restricted Stock until the Vest Date as provided herein.  Every credit of
Restricted Stock under this Plan to a Restricted Stock Account shall be
considered "contingent" and unfunded until the Vest Date.  Such contingent
credits shall be considered bookkeeping entries only, notwithstanding the
"crediting" of "dividends" as provided herein.  Such accounts shall be subject
to the general claims of the Company's creditors.  The Participant's rights to
the Restricted Stock Account shall be no greater than that of a general creditor
of the Company.  Nothing contained herein shall be construed as creating a trust
or fiduciary relationship between the Participants and the Company, the Board of
Directors or the Committee.

         (iii)   Restrictions.  The terms, conditions, and restrictions of the
                 ------------
Restricted Stock shall be determined by the Committee on the Date of Grant.  The
Restricted Stock may not be sold, assigned, transferred, redeemed, pledged or
otherwise encumbered during the period in which the terms, conditions and
restrictions apply (the "Restriction Period").  More than one grant of
                         ------------------
Restricted Stock may be outstanding at any one time, and the Restriction Periods
may be of different lengths.  Receipt of the Restricted Stock is conditioned
upon satisfactory compliance with the terms, conditions and restrictions of this
Plan and those imposed by the Committee.

         (iv)  Restricted Stock Criteria.  At the time of each grant of
               -------------------------
Restricted Stock, the Committee in its sole discretion may establish certain
criteria to determine the times at which restrictions placed on Restricted Stock
shall lapse (i.e., the termination of the Restriction Period), which criteria
may include without limitation performance measures and targets and/or holding
period requirements (the "Restricted Stock Criteria").  The Committee may
                          -------------------------
establish a corresponding relationship between the Restricted Stock Criteria and
(i) the number of Shares of Restricted Stock that may be earned, and (ii) the
extent to which the terms, conditions and restrictions on the Restricted Stock
shall lapse.  Restricted Stock Criteria may vary among grants of Restricted
Stock; provided, however, that once the Restricted Stock Criteria are
       --------  -------
established for a grant of Restricted Stock, the Restricted Stock Criteria shall
not be modified with respect to that grant.

         (v)  Vesting.   On the date the Restriction Period terminates, the
              -------
Restricted Stock shall vest in the Participant (the "Vest Date"), who may then
                                                     ---------
require the Company to issue certificates evidencing the Restricted Stock
credited to the Restricted Stock Account of such Participant.

         (vi)  Dividends.  The Committee may provide from time to time that
               ---------
amounts equivalent to dividends shall be payable with respect to the Restricted
Stock held in the Restricted Stock Account of a Participant.  Such amounts shall
be credited to the Restricted Stock Account and shall be payable to the
Participant on the Vest Date.

         (vii)    Termination of Services.  If a Participant (x) with the
                  -----------------------
consent of the Committee, ceases to be an Employee of, or otherwise ceases to
provide Services to, the Company or any of its Subsidiaries, or (y) dies or
<PAGE>

suffers from Permanent and Total Disability, the vesting or forfeiture
(including without limitation the terms, conditions and restrictions) of any
grant under this Section 7 shall be determined by the Committee in its sole
discretion, subject to any limitations or terms of this Plan.  If the
Participant ceases to be an Employee of, or otherwise ceases to provide Services
to, the Company or any of its Subsidiaries for any other reason, all grants of
Restricted Stock under this Plan shall be forfeited (subject to the terms of
this Plan).

     (b)  Deferral of Payments.    The Committee may establish procedures by
          --------------------
which a Participant may elect to defer the transfer of Restricted Stock to the
Participant.  The Committee shall determine the terms and conditions of such
deferral in its sole discretion.

     (c) Payment of Taxes.  Notwithstanding the provisions of Section 7(a)(v)
         ----------------
above, the Company will not be required to issue any Restricted Stock unless and
until the Participant shall pay to the Company an amount equal to any
withholding and other applicable taxes related to the issuance of the Restricted
Stock.  Such payment shall be made in cash, by certified check, or if authorized
by the Committee, by delivery of other Shares having a Fair Market Value on the
date of delivery equal to such payment or by any combination of such methods of
payment or by any other method of payment as may be permitted under applicable
law and authorized by the Committee.

                                   SECTION 8
                              ISSUANCE OF SHARES
                              ------------------

     As a condition to the transfer of any Shares issued under this Plan, the
Company may require an opinion of counsel, satisfactory to the Company, to the
effect that such transfer will not be in violation of the Securities Act of
1933, as amended (the "Securities Act"), or any other applicable securities
                       --------------
laws, rules or regulations, or that such transfer has been registered under
federal and all applicable state securities laws.  The Company may refrain from
delivering or transferring Shares issued under this Plan until the Committee has
determined that the Participant has tendered to the Company any and all
applicable federal, state or local tax owed by the Participant as the result of
the receipt of a Plan Award, the exercise of an Option or the disposition of any
Shares issued under this Plan, in the event that the Company reasonably
determines that it might have a legal liability to satisfy such tax.  The
Company shall not be liable to any person or entity for damages due to any delay
in the delivery or issuance of any stock certificate evidencing any Shares for
any reason whatsoever.

                                   SECTION 9
                      CAPITALIZATION ADJUSTMENTS; MERGER
                      ----------------------------------

     (a) Adjustments Upon Changes in Capitalization.  Subject to any required
         ------------------------------------------
action by the stockholders of the Company, the number of Shares covered by each
outstanding Option, the aggregate number of Shares that have been authorized for
issuance under this Plan, the maximum number of Shares that an Employee may
receive rights to pursuant to Section 6(k) of this Plan, and the number of
Shares of Restricted Stock credited to any Restricted Stock Account of a
Participant (as well as the Exercise Price covered by any outstanding Option),
shall be proportionately adjusted for any increase or decrease in the number of
issued Shares resulting from a stock split, payment of a stock dividend with
respect to the Stock or any other increase or decrease in the number of issued
Shares effected without receipt of consideration by the Company.  Such
adjustment shall be made by the Committee in its sole discretion, which
adjustment shall be final, binding, and conclusive.  Except as expressly
provided herein, no issuance by the Company of shares of stock of any class
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of Shares subject to an Option.

     (b) Dissolution, Liquidation, Sale of Assets or Merger.  In the event of
         --------------------------------------------------
the proposed dissolution or liquidation of the Company, or a proposed sale of
all or substantially all of the assets of the Company, or the proposed merger of
the Company with or into another corporation where the Company is not the
surviving entity, any Options and grants of Restricted Stock shall terminate
immediately prior to the consummation of such proposed action, unless otherwise
provided in the Stock Option Agreement or by the Committee.  The Committee may,
in the exercise of its sole discretion, in such instances declare that any
Option shall terminate as of a date fixed by the Committee and give each
Optionee the right to exercise the Optionee's Option as to all or any part of
the Shares covered by such Option, including Shares as to which the Option would
not otherwise be exercisable.  Notwithstanding the provisions of Section 6(b) to
the contrary, the Committee may, in the exercise of its sole discretion, provide
in any Stock Option Agreement
<PAGE>

or under any grant of Restricted Stock that the applicable Plan Award shall
become immediately vested in the event of a change in control of the Company or
other extraordinary events as defined by the Committee.

                                  SECTION 10
                             NO EMPLOYMENT RIGHTS
                             --------------------

     No provision of this Plan, under any Stock Option Agreement or under any
grant of Restricted Stock shall be construed to give any Participant any right
to remain an Employee of, or provide Services to, the Company or any of its
Subsidiaries or to affect the right of the Company to terminate any
Participant's service at any time, with or without cause.

                                  SECTION 11
                             STOCKHOLDER APPROVAL
                             --------------------

     With respect to any amendment to this Plan adopted by the Committee that is
required to be approved by the Company's stockholders pursuant to the terms of
Section 12 of this Plan, such approval shall be obtained within twelve (12)
months after the date such amendment is adopted by the Committee; provided, that
                                                                  --------
such amendment shall not become effective until such approval has been obtained.

     If the Company is required to comply with section 14(c) of the Exchange
Act, the approval by the Company's stockholders of this Plan, and their approval
of any subsequent amendment to this Plan requiring their approval, shall be
solicited substantially in accordance with section 14(a) of the Exchange Act and
the rules and regulations promulgated thereunder.  If the Company is not
required to comply with section 14(a) of the Exchange Act at the time of seeking
such approval and such approval is not solicited substantially in accordance
with the rules and regulations, if any, in effect under section 14(a) of the
Exchange Act at the time of such approval, the Company shall furnish in writing
to the holders of record of the securities entitled to vote for this Plan
substantially the same information concerning this Plan which would be required
by the rules and regulations in effect under section 14(a) of the Exchange Act
at the time that such information is furnished, if proxies to be voted with
respect to the approval or disapproval of this Plan were then being solicited,
on or prior to the date of the first annual meeting of security holders held
subsequent to the later of: (i) the first registration of an equity security
under Section 12 of the Act or (ii) the acquisition of an equity security which
exemption from section 16(b) under the Exchange Act is claimed.

                                 SECTION 12
              TERM OF PLAN; EFFECT OF AMENDMENT OR TERMINATION
              ------------------------------------------------

     (a) Term of Plan.  This Plan shall become effective upon its adoption by
         ------------
the Board of Directors subject to the condition subsequent that this Plan is
approved by the stockholders of the Company.  This Plan shall continue in effect
for a term of ten (10) years unless sooner terminated under this Section 12.

     (b) Amendment and Termination.  The Committee in its sole discretion may
         -------------------------
terminate this Plan at any time.  The Committee may amend this Plan at any time
in such respects as the Committee may deem advisable; provided, that the
                                                      --------
following amendments shall require approval of the holders of a majority of the
outstanding Shares entitled to vote:

         (i)   Any change in the aggregate number of Shares that may be issued
under this Plan, other than in connection with an adjustment under Section 9 of
this Plan;

         (ii)  Any change in the designation of the Participants eligible to be
granted Plan Awards; or

         (iii) Any change in this Plan that would materially increase the
benefits accruing to Participants under this Plan.

     (c) Effect of Termination.  In the event this Plan is terminated, no Shares
         ---------------------
shall be issued under this Plan nor shall any Shares of Restricted Stock be
credited to a Restricted Stock Account, except upon exercise of an Option
granted prior to such termination or issuance of Shares of Restricted Stock
previously credited to a Restricted Stock
<PAGE>

Account. The termination of this Plan, or any amendment thereof, shall not
affect any Shares previously issued to a Participant, any Option previously
granted under this Plan or any Restricted Stock previously credited to a
Restricted Stock Account.

     THIS PLAN AND ANY AND ALL STOCK OPTION AGREEMENTS AND AGREEMENTS RELATING

                                ADMINISTRATION
                                --------------

     (a) General Administration.  This Plan shall be administered by the
         ----------------------
Committee, which shall consist of at least two (2) persons who shall be members
of the Board of Directors but who do not qualify as Non-employee Directors.  The
members of the Committee shall be appointed by the Board of Directors for such
terms as the Board of Directors may determine.  The Board of Directors may from
time to time remove members from, or add members to, the Committee.  Vacancies
on the Committee, however caused, shall be filled by the Board of Directors.
The Board of Directors at any time may terminate the authority delegated to any
committee of the Board of Directors pursuant to this Section 3(a) and revest in
the Board of Directors the administration of this Plan.

     (b) Committee Procedures.  The Board of Directors shall designate one of
         --------------------
the members of the Committee as chairman. The Committee may hold meetings at
such times places, and in such manner as it shall determine. The acts of a
majority of the Committee members present at meetings at which a quorum exists,
or acts reduced to or proved in writing by a majority of all Committee members
shall be valid acts of the Committee. A majority of the Committee shall
constitute a quorum.

     (c) Authority of Committee.  This Plan shall be administered in such a
         ----------------------
manner as to comply with all terms of Rule 16b-3 (or any successor rule) under
the Exchange Act. The Committee shall have no authority, discretion, or power to
select the Non-employee Directors who will receive Options hereunder or to set
the number of shares to be covered by each Option granted hereunder, the
exercise price of such Option, the timing of the grant of such Option or the
period within which such Option may be exercised. The Committee may delegate
administrative duties to such employees of the Company as it deems proper, so
long as such delegation is not otherwise prohibited by Rule 16b-3 under the
Exchange Act.

     (d) Committee Determinations Binding.  Subject to the limitations set forth
         --------------------------------
above, the Committee may adopt, alter, and repeal administrative rules,
guidelines and practices governing this Plan as it from time to time shall deem
advisable, may interpret the terms and provisions of this Plan, any Option and
any Option Agreement and may otherwise supervise the administration of this
Plan. All decisions made by the Committee under this Plan shall be binding on
all persons, including the Company and Optionees. No member of the Committee
shall be liable for any action that he or she has in good faith taken or failed
to take with respect to this Plan or any Option.

                                  ELIGIBILITY
                                  -----------

     Only Non-employee Directors may receive Options under this Plan.


                                   SECTION 5
                            SHARES SUBJECT TO PLAN
                            ----------------------

     (a) Basic Limitation.  Shares offered under this Plan may be authorized
         ----------------
but unissued Shares or Shares that have been reacquired by the Company. The
aggregate number of Shares that are available for issuance under this Plan shall
not exceed one hundred thousand (100,000) Shares, subject to adjustment pursuant
to Section 9 of this Plan. The Committee shall not issue more Shares than are
available for issuance under this Plan. The number of Shares that are subject to
unexercised Options at any time under this Plan shall not exceed the number of
Shares that remain available for issuance under this Plan. The Company, during
the term of this Plan, shall at all times reserve and keep available sufficient
Shares to satisfy the requirements of this Plan.

     (b) Additional Shares.  In the event any outstanding Option for any reason
         -----------------
expires, is canceled or otherwise terminates, the Shares allocable to the
unexercised portion of such Option shall again be available for issuance under
this Plan.


                                   SECTION 6
                           NON-DISCRETIONARY GRANTS
                           ------------------------

     (a) Initial Grant.  Subject to the restrictions listed below, each
         -------------
Non-employee Director elected upon the date of his or her initial election to be
a Non-employee Director shall be granted automatically an option to purchase ten
thousand (10,000) shares of Common Stock of the Company on the terms and
conditions set forth herein.  Any Non-employee Director who is serving as such
as of the Effective Date of this Plan and has been serving for less than six (6)
months as a Non-employee Director or in a similar capacity for any predecessor
of the Company shall also receive this initial grant of Options as of the
Effective Date of this Plan if, and only if, such Non-employee Director has not
received for such services prior to the Effective Date any other equity
ownership rights from the Company or any predecessor entity.

     (b) Subsequent Grants.  Each Non-employee Director shall be granted
         -----------------
automatically an Option to purchase three thousand (3,000) Shares on April 1 of
each year (the "April Grant Date"), provided the individual is a Non-employee
                ----------------
Director as of the April Grant Date, and has been a Non-employee Director for at
least one (1) year prior to the April Grant Date.  If such individual has been a
Non-employee Director for less than one (1) year as of the April Grant Date,
then such individual shall be granted automatically an Option to purchase two
hundred fifty (250) Shares for each full month such individual has served as a
Non-employee Director prior to the April Grant Date.  Any service as a Non-
employee Director of the Company or its predecessor prior to the Effective Date
of this Plan shall be counted for purposes of the 1997 April Grant Date.

     (c) Prior Options.  Any Non-employee Director who is serving as such as of
         -------------
the Effective Date of this Plan who holds stock options of the Company for
serving as a Non-employee Director or in a similar capacity for any predecessor
of the Company may receive a grant of Options under this Plan in exchange for
such prior options on terms and conditions and as determined by the Committee in
its sole discretion.


                                   SECTION 7
                        TERMS AND CONDITIONS OF OPTIONS
                        -------------------------------

     (a) Term of Option.  The term of each Option shall commence on the date it
         --------------
is granted and, unless
<PAGE>

sooner terminated as set forth herein, shall expire on the date ("Expiration
                                                                  ----------
Date") ten (10) years from the date of grant.
- ----

     (b) Vesting of Options.  Subject to the other provisions of this Plan, each
         ------------------
Option granted pursuant to this Plan shall become exercisable in installments
cumulatively as to fifty percent (50%) of the Shares subject to each Option on
each of the first and second annual anniversaries of the date of grant of the
Option. Notwithstanding the preceding sentence to the contrary, each Option
granted pursuant to this Plan shall become immediately exercisable in the event
of a Change in Control as of the effective date thereof.

     (c) Exercise Price and Method of Payment.
         ------------------------------------

         (i)  Exercise Price.  The Exercise Price of each Option shall be one
              --------------
hundred percent (100%) of the Fair Market Value of the Shares subject to such
Option on the date such Option is granted.

         (ii) Payment of Shares.  Payment for the Shares upon exercise of an
              -----------------
Option shall be made in cash, by certified check, or if authorized by the
Committee, by delivery of other Shares having a Fair Market Value on the date of
delivery equal to the aggregate exercise price of the Shares as to which said
Option is being exercised, or by any combination of such methods of payment or
by any other method of payment as may be permitted under applicable law and this
Plan and authorized by the Committee pursuant to the provisions of this Plan.

     (d)  Exercise of Option.
          ------------------

         (i)  Procedure for Exercise; Rights of Stockholder.  Any Option granted
              ---------------------------------------------
hereunder shall be exercisable at such times as set forth in Section 7(b)
hereof, provided, however, that no Option shall be exercisable prior to
stockholder approval of this Plan in accordance with Section 13 hereof.

     An Option may not be exercised for a fraction of a Share.

     An Option shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the Stock
Option Agreement by the Optionee entitled to exercise the Option and full
payment for the Shares and any withholding and other applicable taxes with
respect to which the Option is exercised has been received by the Company. Full
payment may, as authorized by the Committee, consist of any form of
consideration and method of payment allowable under Section 7(c)(ii) of this
Plan. Upon the receipt of notice of exercise and full payment for the Shares and
taxes, the Shares shall be deemed to have been issued and the Optionee shall be
entitled to receive such Shares and shall be a stockholder with respect to such
Shares, and the Shares shall be considered fully paid and nonassessable. No
adjustment will be made for a dividend or other right for which the record date
is prior to the date on which the stock certificate is issued, except as
provided in Section 9 of this Plan.

     Each exercise of an Option shall reduce, by an equal number, the total
number of Shares that may thereafter be purchased under such Option.

         (ii) Termination of Status as a Director.  If a Non-employee Director
               -----------------------------------
ceases to serve as a director of or consultant to the Company, he or she may,
but only until the earlier of the date (i) the Option held by the Optionee
expires, or (ii) ninety (90) days after the date such Optionee ceases to be a
director or consultant, exercise the Option to the extent that the Optionee was
entitled to exercise it on such date.  To the extent that the Optionee was not
entitled to exercise an Option on such date, or if the Optionee does not
exercise it within the time specified herein, such Option shall terminate.

         (iii) Permanent and Total Disability.   Notwithstanding the provisions
                ------------------------------
of Section 7(d)(ii) above, in the event an Optionee is unable to continue to
perform services for the Company or any of its Affiliates as a result of such
Optionee's Permanent and Total Disability, such Optionee may exercise an Option
in whole or in part to the extent that the Optionee was entitled to exercise it
on such date, but only until the earlier of the date (i) the Option held by the
Optionee expires, or (ii) twelve (12) months from the date of termination of
services due to such
<PAGE>

Permanent and Total Disability. To the extent the Optionee is not entitled to
exercise an Option on such date or if the Optionee does not exercise it within
the time specified herein, such Option shall terminate.

         (iv) Death of an Optionee.  Upon the death of an Optionee, any Option
              --------------------
held by an Optionee shall terminate and be of no further effect; provided,
                                                                 --------
however, notwithstanding the provisions of Section 7(d)(ii) above, in the event
- -------
an Optionee's death occurs during the term of an Option held by such Optionee
and, at the time of death, the Optionee was a director of or consultant to the
Company, the Option may be exercised in whole or in part to the extent that the
Optionee was entitled to exercise it on such date, but only until the earlier of
the date (i) the Option held by the Optionee expires, or (ii) twelve (12) months
from the date of the Optionee's death, by the Optionee's estate or by a person
who acquired the right to exercise the Option by bequest or inheritance. To the
extent the Option is not entitled to be exercised on such date or if the Option
is not exercised within the time specified herein, such Option shall terminate.

     (e) Non-Transferability of Options.  No Option granted under this Plan
         ------------------------------
may be sold, pledged, assigned, hypothecated, transferred or disposed of in any
manner other than by will or by the laws of descent and distribution or pursuant
to a qualified domestic relations order as defined by the Code or Title I of the
Employee Retirement Income Security Act, or the rules thereunder, and no Option
granted under this Plan is assignable by operation of law or subject to
execution, attachment or similar process.  Any Option granted under this Plan
can only be exercised during the Optionee's lifetime by such Optionee unless
exercised pursuant to Section 7(d)(iv).  Any attempted sale, pledge, assignment,
hypothecation or other transfer of the Option contrary to the provisions hereof
and the levy of any execution, attachment or similar process upon the Option
shall be null and void and without force or effect.  No transfer of the Option
by will or by the laws of descent and distribution shall be effective to bind
the Company unless the Company shall have been furnished written notice thereof
and an authenticated copy of the will and/or such other evidence as the
Committee may deem necessary to establish the validity of the transfer and the
acceptance by the transferee or transferees of the terms and conditions of the
Option.  The terms of any Option transferred by will or by the laws of descent
and distribution shall be binding upon the executors, administrators, heirs and
successors of Optionee.

     (f) Time of Granting Options.  Any Option granted hereunder shall be deemed
         ------------------------
to be granted on the date of grant. Written notice of the Committee's
determination to grant an Option to a Non-employee Director, evidenced by a
Stock Option Agreement, dated as of the date of grant, shall be given to such
Non-employee Director within a reasonable time after the date of grant.

     Early Exercise.  In the Committee's sole and absolute discretion, an Option
     --------------
may include a provision whereby the Optionee may elect at anytime while a Non-
employee Director to exercise the Option as to any part or all of the Shares
subject to the Option prior to the full vesting of the Option. Any unvested
Shares so purchased shall be subject to a repurchase right in favor of the
Company, with the repurchase price to be equal to the original purchase price of
the Shares, or to any other restriction the Committee determines to be
appropriate, provided however, that (i) the right to repurchase at the original
purchase price shall lapse at a rate equal to the remaining portion of the
original vesting schedule of the Shares so purchased, (ii) such repurchase right
shall be exercisable by the Company within (A) the ninety (90) day period
following the termination of service as a Non-employee Director for any reason
whatsoever, or (B) such longer period as may be agreed to by the Company and the
Optionee (for example, for purposes of satisfying the requirements of Section
1202(c)(3) of the Code (regarding "qualified small business stock")), and (iii)
such repurchase right shall be exercisable for cash or cancellation of purchase
money indebtedness for the Shares. Should the right of repurchase be assigned by
the Company, the assignee shall pay the Company cash equal to the difference
between the original purchase price and stock's fair market value if the
original purchase price is less than the stock's fair market value.


                                   SECTION 8
                              ISSUANCE OF SHARES
                              ------------------

     As a condition to the transfer of any Shares issued under this Plan, the
Company may require an opinion of counsel, satisfactory to the Company, to the
effect that such transfer will not be in violation of the Securities Act of
<PAGE>

1933, as amended (the "Securities Act"), or any other applicable securities
                       --------------
laws, rules or regulations, or that such transfer has been registered under
federal and all applicable state securities laws.  The Company may refrain from
delivering or transferring Shares issued under this Plan until the Committee has
determined that the Optionee has tendered to the Company any and all applicable
federal, state or local tax owed by the Optionee as the result of the receipt of
an Option, the exercise of an Option or the disposition of any Shares issued
under this Plan, in the event that the Company reasonably determines that it
might have a legal liability to satisfy such tax.  The Company shall not be
liable to any person or entity for damages due to any delay in the delivery or
issuance of any stock certificate evidencing any Shares for any reason
whatsoever.


                                   SECTION 9
                      CAPITALIZATION ADJUSTMENTS; MERGER
                      ----------------------------------

     (a) Adjustments Upon Changes in Capitalization.  Subject to any required
         ------------------------------------------
action by the stockholders of the Company, the number of Shares covered by each
outstanding Option and the aggregate number of Shares that have been authorized
for issuance under this Plan (as well as the exercise price covered by any
outstanding Option), shall be proportionately adjusted for any increase or
decrease in the number of issued Shares resulting from a stock split, payment of
a stock dividend with respect to the Common Stock or any other increase or
decrease in the number of issued Shares effected without receipt of
consideration by the Company.  Such adjustment shall be made by the Committee in
its sole discretion, which adjustment shall be final, binding, and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class shall affect, and no adjustment by reason thereof shall be
made with respect to, the number or price of Shares subject to an Option.

     (b) Dissolution, Liquidation, Sale of Assets or Merger.  In the event of
         --------------------------------------------------
the proposed dissolution or liquidation of the Company, or a proposed sale of
all or substantially all of the assets of the Company, or the proposed merger of
the Company with or into another corporation where the Company is not the
surviving entity, any Options shall terminate immediately prior to the
consummation of such proposed action, unless otherwise provided by the
Committee.  The Committee may, in the exercise of its sole discretion, in such
instances declare that any Option shall terminate as of a date fixed by the
Committee and give each Optionee the right to exercise the Optionee's Option as
to all or any part of the Shares covered by such Option, including Shares as to
which the Option would not otherwise be exercisable.


                                  SECTION 10
                           NO RIGHTS TO DIRECTORSHIP
                           -------------------------

     No provision of this Plan, or under any Stock Option Agreement, shall be
construed to give any Optionee any rights with respect to the continuation of
the Optionee's membership on the Board of Directors or shall interfere in any
way with provisions in the Company's Certificate of Incorporation and Bylaws
relating to the election, appointment, terms of office, and removal of members
of the Board of Directors.


                                  SECTION 11
               TERM OF PLAN; EFFECT OF AMENDMENT OR TERMINATION
               ------------------------------------------------

     (a) Term of Plan.  This Plan shall become effective upon its adoption by
         ------------
the Board of Directors.  This Plan shall continue in effect for a term of ten
(10) years unless sooner terminated under this Section 11.

     (b) Amendment and Termination.  The Board of Directors may terminate this
         -------------------------
Plan at any time as the Board of Directors may deem advisable.  The Committee
may amend this Plan at any time, provided, however, that the Committee shall not
amend this Plan with respect to the provisions of this Plan which relate to who
is granted Options, the amount, price and timing of grants, or the period within
which each Option may be exercised and may not be amended more than once every
six (6) months, other than to comport with changes in the Code, the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), or the rules
                                                     -----
thereunder.  Except as provided in
<PAGE>

Section 9 relating to adjustments upon changes in capitalization, no amendment
shall be effective unless approved by the stockholders of the Company within
twelve (12) months before or after the adoption of the amendment, where the
amendment will:

         (i)   increase the number of shares which may be issued under this
Plan;

         (ii)  modify the requirements as to eligibility for participation in
this Plan (to the extent such modification requires stockholder approval in
order for this Plan to comply with the requirements of Rule 16b-3); or

         (iii) modify this Plan in any other way if such modification requires
stockholder approval in order for this Plan to comply with the requirements of
Rule 16b-3.

     (c) Rights and obligations under any option granted before any amendment of
this Plan shall not be impaired by such amendment unless (i) the Company
requests the consent of the person to whom the option was granted and (ii) such
person consents in writing.

     (d) Effect of Termination.  In the event this Plan is terminated, no Shares
         ---------------------
shall be issued under this Plan, except upon exercise of an Option granted prior
to such termination.  The termination of this Plan, or any amendment thereof,
shall not affect any Shares previously issued to a Participant or any Option
previously granted under this Plan.


                                  SECTION 12
                        LEGAL REQUIREMENTS; RULE 16b-3
                        ------------------------------

     (a) Legal Requirements.  The Company shall not be obligated to offer or
         ------------------
sell any Shares upon exercise of any Option unless the Shares are at that time
effectively registered or exempt from registration under the federal and
applicable state securities laws and the offer and sale of the Shares are
otherwise in compliance with all applicable securities laws and the regulations
of any stock exchange on which the Company's securities may then be listed.  The
Company shall have no obligation to register the securities covered by this Plan
under the federal securities laws or take any other steps as may be necessary to
enable the securities covered by this Plan to be offered and sold under federal
or other securities laws.  Upon exercising all or any portion or an Option, an
Optionee may be required to furnish representations or undertakings deemed
appropriate by the Company to enable the offer and sale of the Shares or
subsequent transfers of any interest in the Shares to comply with applicable
securities laws.  Certificates evidencing Shares acquired upon exercise of
Options shall bear any legend required by, or useful for purposes of compliance
with, applicable securities laws, this Plan or the Stock Option Agreements.

     (b) Rule 16b-3.  With respect to persons subject to Section 16 of the
         ----------
Exchange Act, transactions under this Plan are intended to comply with the
applicable conditions of Rule 16b-3 under the Exchange Act.  To the extent any
provision of this Plan or action by the Committee fails to so comply, it shall
be adjusted to comply with Rule 16b-3, to the extent permitted by law and deemed
advisable by the Committee.  It shall be the responsibility of persons subject
to Section 16 of the Exchange Act, not of the Company or the Committee, to
comply with the requirements of Section 16 of the Exchange Act; and neither the
Company nor the Committee shall be liable if this Plan or any transaction under
this Plan fails to comply with the applicable conditions of Rule 16b-3, or if
any such person incurs any liability under Section 16 of the Exchange Act.


                                  SECTION 13
                EFFECTIVE DATE OF PLAN; CONDITIONS OF EXERCISE
                ----------------------------------------------

     (a) This Plan shall become effective upon adoption by the Board of
Directors subject to the condition subsequent that this Plan is approved by the
stockholders of the Company.
<PAGE>

     (b) No Option granted under this Plan shall be exercised or exercisable
unless and until the condition of Section 13(a) above has been met.


                                  SECTION 14
                                 GOVERNING LAW
                                 -------------

WITH THIS PLAN SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF DELAWARE, WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES.

<PAGE>

               (b)  Shares of Common Stock issuable or issued to employees,

               (f)  Shares of Common Stock issued or issuable upon conversion
of Series A Preferred Stock, Series B Preferred Stock, or Series C Preferred
Stock,

               (g)  Shares of Common Stock issued or issuable in a public
offering prior to or in connection with which all outstanding shares of Series

Stock, issued in connection with the licensing or acquisition of intellectual

approved by the Board of Directors of the Company, and

               (j)  Shares of Series C Preferred Stock issued pursuant to the
Stock Purchase Agreement.

               Notwithstanding the preceding provisions of this Section 4.2 to
the contrary, New Securities shall include the aggregate amount of shares of
Common Stock, if any, issued pursuant to subsections (b), (c), (d), or (i)
above the extent such shares exceed an amount equal to fifteen percent (15%)

adjusted for any stock dividends, combinations, or splits with respect to such
shares.)

          4.3  In the event the Company proposes to undertake an issuance of New
Securities, it shall give to each Investor written notice (the "Notice") of its
                                                                ------
intention,

                                 Page 6 of 24
<PAGE>

describing the type of New Securities, the price, the terms upon which the
Company proposes to issue the same, the number of shares that such Investor is
entitled to purchase, and a statement that Investor shall have twenty (20) days
to respond to such Notice. Investor shall have twenty (20) days from the date of
receipt of the Notice to agree to purchase any or all of its Pro Rata Share of
the New Securities for the price and upon the terms specified in the Notice by
giving written notice to the Company and stating therein the quantity of New
Securities to be purchased and forwarding payment for such New Securities to the
Company if immediate payment is required by such terms.

          4.4  In the event Investor fails to exercise in full the right of
first refusal within said twenty (20) day period, the Company shall have sixty
(60) days thereafter to sell or enter into an agreement (pursuant to which the
sale of New Securities covered thereby shall be closed, if at all, within
thirty (30) days from date of said agreement) to sell the New Securities
respecting which Investor's rights were not exercised, at a price and upon
general terms no more favorable to the purchaser thereof than specified in the
Notice. In the event the Company has not sold the New Securities within said
sixty (60) day period (or sold and issued New Securities in accordance with
the foregoing within thirty (30) days from the date of said agreement), the
Company shall not thereafter issue or sell any New Securities without first
offering such securities to such Investor in the manner provided above.

          4.5. The covenants of the Company set forth in this Section 4 shall
terminate upon conversion of any shares of Series A Preferred Stock or Series B
Preferred Stock or Series C Preferred Stock with respect to such shares
converted.

     5.   Demand Registration

          5.1  Request for Registration on Form Other Than Form S-3

               5.1.1  Subject to the terms of this Agreement, in the event
that the Company shall receive a written request from a Holder or Holders of
Registrable Securities obtained from the conversion of Series A Preferred
Stock requesting that the Company effect a Registration with respect to all or
a part of the Registrable Securities on a form other than Form S-3 for an
offering greater than 25% of the then outstanding Registrable Securities
obtained from the conversion of Series A Preferred Stock (or any lesser
percent if the reasonably anticipated aggregate offering price to the public
would exceed $15,000,000), the Company shall (i) promptly give written notice
of the proposed Registration to all other Holders and (ii) as soon as
practicable, use its reasonable best efforts to effect Registration of the
Registrable Securities specified in such request, together with any
Registrable Securities of any Holder joining in such request as are specified
in a written request given within twenty (20) days after written notice from
the Company. The Company shall not be obligated to take any action to effect
any such registration pursuant to this Section 5.1.1 (i) at any time within
One Hundred Eighty (180) days following the effective date of any Registration
Statement on Form S-1 (or any successor form), or (ii) at any time prior to
September 3, 1999, or (iii) if the

                                 Page 7 of 24
<PAGE>

Company has previously effected one (1) such Registration pursuant to this
Section 5.1.1. A Registration that is withdrawn or otherwise abandoned at the
request of such Holders will count towards the preceding limitation of one (1)
Registration unless at the time of such withdrawal or abandonment the Holders
have learned of a material adverse change in the financial condition or business
of the Company from that known to the Holders at the time of their request and
have withdrawn or abandoned their request following disclosure by the Company of
such material adverse change. The provisions of Section 5.4 shall be applicable
to each registration initiated under this Section 5.1.1.

               5.1.2  Subject to the terms of this Agreement, in the event
that the Company shall receive a written request from a Holder or Holders of
Registrable Securities obtained from the conversion of Series B Preferred
Stock requesting that the Company effect a Registration with respect to all or
a part of the Registrable Securities on a form other than Form S-3 for an
offering greater than 25% of the then outstanding Registrable Securities
obtained from the conversion of Series B Preferred Stock (or any lesser
percent if the reasonably anticipated aggregate offering price to the public
would exceed $15,000,000), the Company shall (i) promptly give written notice
of the proposed Registration to all other Holders and (ii) as soon as
practicable, use its reasonable best efforts to effect Registration of the
Registrable Securities specified in such request, together with any
Registrable Securities of any Holder joining in such request as are specified
in a written request given within twenty (20) days after written notice from
the Company. The Company shall not be obligated to take any action to effect
any such registration pursuant to this Section 5.1.2 (i) at any time within
One Hundred Eighty (180) days following the effective date of any Registration
Statement on Form S-1 (or any successor form), or (ii) at any time prior to
July 7, 2000, or (iii) if the Company has previously effected one (1) such
Registration pursuant to this Section 5.1.2. A Registration that is withdrawn
or otherwise abandoned at the request of such Holders will count towards the
preceding limitation of one (1) Registration unless at the time of such
withdrawal or abandonment the Holders have learned of a material adverse
change in the financial condition or business of the Company from that known
to the Holders at the time of their request and have withdrawn or abandoned
their request following disclosure by the Company of such material adverse
change. The provisions of Section 5.4 shall be applicable to each registration
initiated under this Section 5.1.2.

               5.1.3  Subject to the terms of this Agreement, in the event
that the Company shall receive a written request from a Holder or Holders of
Registrable Securities obtained from the conversion of Series C Preferred
Stock requesting that the Company effect a Registration with respect to all or
a part of the Registrable Securities on a form other than Form S-3 for an
offering greater than 25% of the then outstanding Registrable Securities
obtained from the conversion of Series C Preferred Stock (or any lesser
percent if the reasonably anticipated aggregate offering price to the public
would exceed $15,000,000), the Company shall (i) promptly give written notice
of the proposed Registration to all other Holders and (ii) as soon as
practicable, use its reasonable best efforts to effect Registration of the
Registrable Securities specified in such request, together with any
Registrable Securities of any Holder

                                 Page 8 of 24
<PAGE>

joining in such request as are specified in a written request given within
twenty (20) days after written notice from the Company. The Company shall not be
obligated to take any action to effect any such registration pursuant to this
Section 5.1.3 (i) at any time within One Hundred Eighty (180) days following the
effective date of any Registration Statement on Form S-1 (or any successor
form), or (ii) at any time prior to August 3, 2001, or (iii) if the Company has
previously effected one (1) such Registration pursuant to this Section 5.1.3. A
Registration that is withdrawn or otherwise abandoned at the request of such
Holders will count towards the preceding limitation of one (1) Registration
unless at the time of such withdrawal or abandonment the Holders have learned of
a material adverse change in the financial condition or business of the Company
from that known to the Holders at the time of their request and have withdrawn
or abandoned their request following disclosure by the Company of such material
adverse change. The provisions of Section 5.4 shall be applicable to each
registration initiated under this Section 5.1.3.

               5.1.4  Notwithstanding the provisions of Section 5.1.1, Section
5.1.2 and Section 5.1.3, if the Company shall furnish to all such Holders who
joined in the request 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 for any Registration
to be effected as requested under Section 5.1.1, Section 5.1.2 or Section
5.1.3, the Company shall have the right, exercisable not more than once in any
twelve (12) month period, to defer the filing of a Registration Statement with
respect to such offering for a period of not more than ninety (90) days from
delivery of the request of the initiating Holder.

          5.2  Request for Registration on Form S-3

               5.2.1  If a Holder or Holders of outstanding Registrable
Securities request that the Company file a Registration Statement on Form S-3
(or any successor form to Form S-3) for a public offering of shares of
Registrable Securities, and the Company is entitled to use Form S-3 to
register the Registrable Securities for such an offering, the Company shall
(i) promptly give written notice of the proposed Registration to all other
Holders and (ii) as soon as practicable, use its reasonable efforts to effect
Registration of the Registrable Securities specified in such request, together
with any Registrable Securities of any Holder joining in such request as are
specified in a written request given within twenty (20) days after receipt of
written notice from the Company; provided, however, that the Company shall not
be required to effect more than two (2) Registrations pursuant to this Section
5.2 in any twelve (12) month period. Additionally, the Company shall not be
required to effect any Registrations pursuant to this Section 5.2 if the
reasonably anticipated aggregate offering price to the public would not equal
at least $500,000. The provisions of Section 5.4 shall be applicable to each
registration initiated under this Section 5.2.

               5.2.2  Notwithstanding the provisions of Section 5.2.1, if the
Company provides to all Holders who joined in the request a certificate signed
by the President of the Company stating that, in the good faith judgment of the
Board of Directors of the Company,

                                 Page 9 of 24
<PAGE>

it would be seriously detrimental to the Company for any Registration to be
effected as requested under Section 5.2.1, the Company shall have the right,
exercisable not more than once in any twelve (12) month period, to defer the
filing of a Registration Statement with respect to such offering for a period of
not more than ninety (90) days from delivery of the request of the initiating
Holder.

          5.3  Registration of Other Securities in Demand Registration

               Any Registration Statement filed pursuant to the request of the
Holder or Holders under this Section 5 may, subject to the provisions of
Section 5.4, include securities registered for the account of the Company or
other security holders in addition to Registrable Securities.

          5.4  Underwriting in Demand Registration

               5.4.1  Notice of Underwriting

                      If a Holder or Holders intend to distribute the
Registrable Securities covered by their request by means of an underwriting,
they shall so advise the Company as a part of their request made pursuant to
this Section 5, and the Company shall include such information in the written
notice referred to in Section 5.1 or 5.2. The right of any Holder to
Registration pursuant to Section 5 shall be conditioned upon such Holder's
agreement to participate in such underwriting and the inclusion of such
Holder's Registrable Securities in the underwriting.

               5.4.2  Inclusion of Other Holders in Demand Registration

                      If the Company, officers or directors of the Company
holding Common Stock other than Registrable Securities, or holders of
securities other than Registrable Securities, request inclusion in such
Registration, the initiating Holders, to the extent they deem advisable and
consistent with the goals of such Registration, may, in their sole discretion,
on behalf of all Holders, offer to any or all of the Company, such officers or
directors, and such holders of securities other than Registrable Securities
that such securities other than Registrable Securities be included in the
underwriting and may condition such offer on the acceptance by such persons of
the terms of this Section 5. In the event, however, that the number of shares
so included exceeds the number of shares of Registrable Securities included by
all Holders, such Registration shall be treated as governed by Section 6
rather than Section 5, and it shall not count as a Registration for purposes
of Section 5.1.

               5.4.3  Selection of Underwriter in Demand Registration

                      The Company shall (together with all Holders proposing
to distribute their securities through such underwriting) enter into an
underwriting agreement with the representative of the underwriter or
underwriters selected for such underwriting by the

                                 Page 10 of 24
<PAGE>

Holders of a majority of the Registrable Securities being registered by the
initiating Holders and agreed to by the Company.

               5.4.4  Marketing Limitation in Demand Registration

                      In the event the Underwriter's Representative advises
the initiating Holders in writing that market factors (including, without
limitation, the aggregate number of shares of Common Stock requested to be
Registered, the general condition of the market, and the status of the persons
proposing to sell securities pursuant to the Registration) require a
limitation of the number of shares to be underwritten, then (a) first the
Common Stock (other than Registrable Securities) held by officers or directors
of the Company, (b) next the securities other than Registrable Securities, and
(c) last the securities requested to be registered by the Company, shall be
excluded from such Registration to the extent required by such limitation. If
a limitation of the number of shares is still required, the initiating Holders
shall so advise all Holders and 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 entitled to 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 5.4.4 shall be included in such Registration Statement.

               5.4.5  Right of withdrawal in Demand Registration

                      If any Holder of Registrable Securities, or a holder of
other securities entitled (upon request) to be included in such Registration,
disapproves of the terms of the underwriting, such person may elect to
withdraw therefrom by written notice to the Company, the underwriter and the
initiating Holders delivered prior to the effective date of the Registration
Statement. The securities so withdrawn shall also be withdrawn from the
Registration Statement.

6.    Piggyback Registration

          6.1  Notice of Piggyback Registration and Inclusion of Registrable
               Securities

               Subject to the terms of this Agreement, in the event the
Company decides to Register any of its Common Stock (either for its own
account or the account of a security holder or holders exercising demand
registration rights) on a form that would be suitable for a registration
involving solely Registrable Securities, the Company will: (a) promptly give
each Holder written notice thereof (which shall include a list of the
jurisdictions in which the Company intends to attempt to qualify such
securities under the applicable Blue Sky or other state securities laws) and
(b) include in such Registration (and any related qualification under Blue Sky
laws or other compliance), and in any underwriting involved therein, all the

                                 Page 11 of 24
<PAGE>

Registrable Securities specified in a written request delivered to the Company
by any Holder within twenty (20) days after delivery of such written notice from
the Company.

          6.2  Underwriting in Piggyback Registration

               6.2.1  Notice of Underwriting in Piggyback Registration

                      If the Registration of which the Company gives notice is
for a Registered public offering involving an underwriting, the Company shall
so advise the Holders as a part of the written notice given pursuant to
Section 6.1. In such event, the right of any Holder to Registration shall be
conditioned upon such underwriting and the inclusion of such Holder's
Registrable Securities in such underwriting to the extent provided in this
Section 6. All Holders proposing to distribute their securities through such
underwriting shall (together with the Company and the other holders
distributing their securities through such underwriting) enter into an
underwriting agreement with the underwriter's representative for such
offering.

               6.2.2  Marketing Limitation in Piggyback Registration

                      In the event the Underwriter's Representative advises
the Holders seeking registration of Registrable Securities pursuant to Section
6 in writing that market factors (including, without limitation, the aggregate
number of shares of Common Stock requested to be Registered, the general
condition of the market, and the status of the persons proposing to sell
securities pursuant to the Registration) require a limitation of the number of
shares to be underwritten, the Underwriter's Representative (subject to the
allocation priority set forth in Section 6.2.3) may:

                      (a) in the case of the Company's initial Registered
public offering, limit the number of shares of Registrable Securities to be
included in such registration and underwriting to zero; and

                      (b) in the case of any Registered public offering
subsequent to the initial public offering, limit the number of shares of
Registrable Securities to be included in such Registration and underwriting to
not less than fifty percent (50%) of the securities included in such
Registration (based on aggregate market values).

               6.2.3  Allocation of Shares in Piggyback Registration

                      In the event the Underwriter's Representative limits the
number of shares to be included in a Registration pursuant to Section 6.2.2,
the number of shares to be included in such Registration shall be allocated
(subject to Section 6.2.2) in the following manner: The

                                 Page 12 of 24
<PAGE>

shares (other than Registrable Securities) held by officers or directors of the
Company shall be excluded from such registration and underwriting to the extent
required by such limitation. If a limitation of the number of shares is still
required after such exclusion, the number of shares that may be included in the
Registration and underwriting by selling stockholders shall be allocated among
all other Holders thereof, in proportion, as nearly as practicable, to the
respective amounts of securities (including Registrable Securities) which such
Holders would otherwise be entitled to include in such Registration. No
Registrable Securities or other securities excluded from the underwriting by
reason of this Section 6.2.3 shall be included in the Registration Statement.

         6.2.4 Withdrawal in Piggyback Registration

         If any Holder disapproves of the terms of any such underwriting, such
person may elect to withdraw therefrom by written notice to the Company and the
underwriter delivered prior to the effective date of the Registration Statement.
Any Registrable Securities or other securities excluded or withdrawn from such
underwriting shall be withdrawn from such Registration.

7.   Expenses of Registration

     All Registration Expenses incurred in connection with one (1) Registration
pursuant to Section 5.1.1, one (1) Registration pursuant to Section 5.1.2, one
(1) Registration pursuant to Section 5.1.3, two (2) Registrations in each twelve
(12) month period pursuant to Section 5.2, and unlimited Registrations pursuant
to Section 6 shall be borne by the Company. The Company shall not be required to
pay for such expenses of any registration proceeding begun pursuant to Section 5
if the registration request is subsequently withdrawn at the request of the
Holders of a majority of the Registrable Securities to be registered (which
Holders shall bear such expenses), unless the Holders of a majority of the
Registrable Securities agree to forfeit their right to one demand registration
pursuant to Section 5; provided, however, that if at the time of such
withdrawal, the Holders have learned of a material adverse change in the
financial condition or business of the Company from that known to the Holders at
the time of their request and have withdrawn their request 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 5. All Selling Expenses shall be borne by the holders of the securities
Registered pro rata on the basis of the number of shares Registered.

8.   Registration Procedures and Obligations

     Whenever required under this Agreement to effect the registration of any
Registrable Securities, the Company shall, as expeditiously as reasonably
possible:

         (a) Prepare and file with the Commission a Registration Statement with
respect to such Registrable Securities and use its reasonable best efforts to
cause such

                                 Page 13 of 24
<PAGE>

Registration Statement to become effective, and, upon the request of
the Holders of a majority of the Registrable Securities registered thereunder,
keep such Registration Statement effective for up to one hundred twenty (120)
days.

         (b) Prepare and file with the Commission such amendments and
supplements to such Registration Statement and the prospectus used in connection
with such Registration Statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such Registration Statement.

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

         (d) Use 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 or to become subject to taxation in any such states or jurisdictions.

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

         (f) Notify each Holder of Registrable Securities covered by such
Registration Statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such Registration Statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

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

         (h) Furnish, at the request of any Holder requesting Registration of
Registrable Securities pursuant to this Agreement, on the date that such
Registrable Securities are delivered for sale in connection with a registration
pursuant to this Agreement, (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

                                 Page 14 of 24
<PAGE>

underwritten public offering, 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.

9.   Information Furnished by Holder

     It shall be a condition precedent of the Company's obligations under this
Agreement that each Holder of Registrable Securities included in any
Registration furnish to the Company such information regarding such Holder and
the distribution proposed by such Holder or Holders as the Company may
reasonably request.

10.  Rule 144

     10.1   Reports

     With a view to making available to the Holders the benefits of Rule 144
promulgated by the Commission pursuant to the Securities Act ("Rule 144") and
                                                               --------
any other rule or regulation of the Commission 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 Commission 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 so
long as the Company remains subject to the periodic reporting requirements
under Sections 13 or 15(d) of the Exchange Act;

            (b)    include a statement in such public information that the
Company has complied with the reporting requirements of Rule 144 (at any time
after ninety (90) days after the effective date of the first Registration
Statement filed by the Company);

            (c)    take such action, including the voluntary registration of
its Common Stock under Section 12 of the Exchange Act, as is reasonably
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;

            (d)    file with the Commission in a timely manner all reports and
other documents required of the Company under the Securities Act and the
Exchange Act; and

            (e)    furnish to any Holder such other information as may be
reasonably requested and necessary in availing such Holder of any rule or
regulation of the Commission

                                 Page 15 of 24
<PAGE>

which permits the selling of any such securities without Registration or
pursuant to Form S-3.

     10.2  Sales

     Notwithstanding any provision in this Agreement to the contrary, the
covenants of the Company set forth in Section 5 and Section 6 shall terminate as
to any Holder upon the earlier of (i) such time as the Holder qualifies to sell
pursuant to Rule 144 or any similar exemption all of such Holder's shares of
Series A Preferred Stock or Series B Preferred Stock or Series C Preferred Stock
or Registrable Securities obtained from the conversion thereof to the public
within a three (3) month period without registration and without volume
limitations or (ii) the fifth (5th) annual anniversary of the effective date of
the Registration Statement of the Company for the initial offering of its
securities to the general public.

11.  Indemnification

     11.1  Company's Indemnification of Holders

     To the extent permitted by law, the Company will indemnify each Holder,
each of its officers, directors, and constituent partners, legal counsel for the
Holders, and each person controlling such Holder with the meaning of the
Securities Act, with respect to which Registration, qualification, or compliance
of Registrable Securities has been effected pursuant to this Agreement, and each
underwriter, if any, and each person who controls any underwriter, against all
claims, losses, damages, or liabilities (joint or several) (or actions in
respect thereof) to the extent such claims, losses, damages, or liabilities
arise out of or are based upon any untrue statement by the Company or it
officers, directors, or agent (or alleged untrue statement) of a material fact
contained in any prospectus or other document (including any related
Registration Statement) incident to any such Registration, qualification, or
compliance, or are based on any omission by the Company or it officers,
directors, or agent (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, in the light of the circumstances under which they were made, or any
violation by the Company or it officers, directors, or agent of any rule or
regulation promulgated under the Securities Act or the Exchange Act or any state
securities law or any rules or regulations promulgated thereunder applicable to
the Company and relating to action or inaction required of the Company in
connection with any such Registration, qualification, or compliance; and the
Company will reimburse each such Holder, each such underwriter, and each person
who controls any such Holder or underwriter, for any legal and any other
expenses reasonably incurred in connection with investigating or defending any
such claim, loss, damage, liability, or action; provided, however, that the
indemnity contained in this Section 11.1 shall not apply to amounts paid in
settlement of any such claim, loss, damage, liability, or action if settlement
is effected without the consent of the Company (which consent shall not
unreasonably be withheld); provided, further, that the Company will not be
liable in any such case to the extent that any such claim, loss, damage,

                                 Page 16 of 24
<PAGE>

liability, or expense arises directly out of or is based upon any untrue
statement or omission based upon written information furnished to the Company by
such Holder, underwriter, or controlling person and stated to be for use in
connection with such Registration; provided, further, that this indemnity
agreement with respect to a preliminary prospectus shall not inure to the
benefit of any Holder from whom the person asserting any such losses,
liabilities, claims, damages or expenses purchased Registrable Securities, or
any person controlling such Holder, if a copy of the prospectus (as amended or
supplemented at the time of sale) was not sent or given by or on behalf of the
Holder to such person and if the prospectus (as so amended or supplemented)
would have corrected the defect giving rise to such loss, liability, claim,
damage or expense unless such failure to send or give the prospectus resulted
from non-compliance by the Company with Section 8(c) or (f) hereof.

     11.2  Holder's Indemnification of Company

     To the extent permitted by law, each Holder will, if Registrable Securities
held by such Holder are included in the securities as to which such
Registration, qualification or, compliance is being effected pursuant to this
Agreement, indemnify the Company, each of its directors and executive officers,
each legal counsel and independent accountant of the Company, each underwriter,
if any, of the Company's securities covered by such a Registration Statement,
each person who controls the Company or such underwriter within the meaning of
the Securities Act, and each other such Holder, each of its officers, directors,
and constituent partners, and each person controlling such other Holder, against
all claims, losses, damages, and liabilities (or actions in respect thereof)
arising out of or based upon any untrue statement by such Holder (or alleged
untrue statement) of a material fact contained in any such Registration
Statement, prospectus, offering circular, or other document, or any omission by
such Holder (or alleged omission) to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading, in
the light of the circumstances under which they were made, or any violation by
such Holder of any rule or regulation promulgated under the Securities Act or
the Exchange Act or any state securities law or any rules or regulations
promulgated thereunder applicable to such Holder and relating to action or
inaction required of such Holder in connection with any such Registration,
qualification, or compliance, and will reimburse the Company, such Holders, such
directors, officers, partners, persons, law and accounting firms, underwriters
or control persons for any legal and any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage,
liability, or action, in each case to the extent, but in each case only to the
extent that such untrue statement (or alleged untrue statement) or omission (or
alleged omission) is made in such Registration Statement, prospectus, offering
circular, or other document in reliance upon and in conformity with written
information furnished to the Company by a vice president or higher officer or
manager of such Holder if such Holder is not an individual and stated to be
specifically for use in connection with such Registration; provided, however,
that the indemnity contained in this Section 11.2 shall not apply to amounts
paid in settlement of any such claim, loss, damage, liability or action if
settlement is effected without the consent of such Holder (which consent shall
not be

                                 Page 17 of 24
<PAGE>

unreasonably withheld) and provided, further, that each Holder's liability under
this Section 11.2 shall not exceed such Holder's net proceeds from the offering
of securities made in connection with such Registration.

     11.3  Indemnification Procedure

     Promptly after receipt by an indemnified party under this Section 11 of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against an indemnifying party under this
Section 11, notify the indemnifying party in writing of the commencement thereof
and generally summarize such action. The indemnifying party shall have the right
to participate in and to assume the defense of such claim; provided, however,
that the indemnifying party shall be entitled to select counsel for the defense
of such claim with the approval of any parties entitled to indemnification,
which approval shall not be unreasonably withheld; provided further, however,
that if either party reasonably determines that there may be a material conflict
between the position of the Company and the Holders in conducting the defense of
such action, suit, or proceeding by reason of recognized claims for indemnity
under this Section 11, then counsel for such party shall be entitled to conduct
the defense to the extent reasonably determined by such counsel to be necessary
to protect the interest of such party. The failure to notify an indemnifying
party promptly of the commencement of any such action, if prejudicial to the
ability of the indemnifying party to defend such action, shall relieve such
indemnifying party, to the extent so prejudiced, of any liability to the
indemnified party under this Section 11, but the omission so to notify the
indemnifying party will not relieve such party of any liability that such party
may have to any indemnified party otherwise other than under this Section 11.

     11.4  Contribution

     If the indemnification provided for in this Section 11 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. Each Holder's liability under
this Section 11.4 shall not exceed such Holder's net proceeds from the offering
of securities made in connection with such Registration.

     11.5  Survival

     The obligations of the Company and Holders under this Section 11 shall
survive the completion of any offering of Registrable Securities in a
Registration made pursuant hereto.

12.  Transfer of Rights

     The rights to information and inspection under Sections 2 and 3 and the
right to cause the Company to Register securities granted by the Company to such
Investor under this Agreement may be assigned by any Investor to (i) a
transferee who acquires at least 200,000 shares (as adjusted for stock splits,
stock dividends and the like) of Series A Preferred Stock and/or Series B
Preferred Stock and/or Series C Preferred Stock, or (ii) an affiliate of such
Investor which controls, is controlled by, or is under common control with such
Investor; provided, however, that the Company must receive written notice prior
to or within twenty (20) days of the time of said transfer, stating the name and
address of said transferee and identifying the securities with respect to which
such information and Registration rights are being assigned.  This Section 12
shall not diminish or impair restrictions on transfer of Series A Preferred
Stock or Series B Preferred Stock or Series C Preferred Stock as contained in
any agreement executed simultaneously herewith by the parties hereto.

13.  Market Stand-off

     Each Holder hereby agrees that, if so requested by the Company and the
Underwriter's Representative (if any) in connection with the Company's initial
public offering, such Holder shall not sell, make any short sale of, loan, grant
any option for the purchase of, or otherwise transfer or dispose of any
Registrable Securities or other securities of the Company without the prior
written consent of the Company and the Underwriter's Representative for such
period of time (not to exceed 180 days) following the effective date of a
Registration Statement of the Company filed under the Securities Act as may be
requested by the Underwriter's Representative; provided, however, that such
restrictions shall not apply to any transactions relating to any shares of
Common Stock which such Holder purchases in the Company's initial public
offering or in the open market after the completion of such offering.  The
obligations of Holders under this Section 13 shall be conditioned upon similar
agreements being in effect with each other stockholder who then is an officer,
director, or ten percent (10%) stockholder of the Company.

14.  Right of First Refusal

     14.1   Transfers by Investors

     Except as otherwise provided in this Agreement, each Series C Investor
agrees not to sell, transfer, exchange, or assign any right, title, or interest
(a "Transfer") in or to all or any
    --------

                                 Page 19 of 24
<PAGE>

part of its Series C Preferred Stock or Common Stock issued upon conversion
thereof unless it has made an offer (an "Investor Offer") and such offer has not
                                         ---------------
been accepted as provided below.

     14.2 Offer by an Investor

     The Investor Offer shall be made to the Company and to the remaining Series
C Investors and shall consist of a written offer to Transfer all or such part of
the capital stock of the Company owned by the Series C Investor as such Series C
Investor intends to Transfer (the "Offered Investor Shares"). A statement shall
                                   -----------------------
be attached to the Investor Offer which shall provide a full disclosure of the
Investor Offer including (a) a statement of intention to Transfer; (b) the name
and address of any prospective transferee; (c) the number of Offered Investor
Shares; and (d) the terms and conditions of the proposed Transfer, including the
purchase price for the Offered Investor Shares.

     14.3 Acceptance of Offer

          14.3.1  By Company

          Within twenty (20) days after its receipt of the Investor Offer, the
Company or its designee may, in its sole discretion, accept the Investor Offer
by giving written notice to the selling Series C Investor and to the remaining
Series C Investors of the election to accept. In the event the Company does not
provide such written notice within said twenty (20) days then the Company shall
be deemed to have declined to accept the Investor Offer.

          14.3.2  By the Remaining Series C Investors

          If the Investor Offer is not accepted by the Company, each of the
remaining Series C Investors may elect within ten (10) days after decline of the
Investor Offer by the Company to purchase up to such Series C Investor's pro
rata portion of the remaining Offered Investor Shares by giving written notice
within such 10-day period to the selling Investor and to the Company. In the
event a remaining Series C Investor does not provide such written notice within
said 10-day period then such Series C Investor shall be deemed to have declined
to accept the Investor Offer. Said 10-day period for the remaining Series C
Investors shall run sequentially to the 20-day period for the Company as
provided above.

          14.3.3  Pro Rata Portion

          For purposes of this Section 14.1, each accepting Series C Investor's
pro rata portion of the Offered Investor Shares is that proportion of the
Offered Investor Shares multiplied by a fraction, the numerator of which is the
number of shares of Series C Preferred Stock (or

                                 Page 20 of 24
<PAGE>

Common Stock issued upon conversion thereof) then owned by such Series C
Investor and the denominator of which is the aggregate number of shares of
Series C Preferred Stock (or Common Stock issued upon conversion thereof) then
issued and outstanding and held by all non-selling Series C Investors. If any
Series C Investor declines to accept all or any part of its pro rata portion of
the Offered Investor Shares, then each of the Series C Investors who has elected
to purchase pursuant to Section 14.3.2 shall have an additional 5-day period
within which such accepting Series C Investors may additionally accept up to its
pro rata portion of the declining Series C Investor's unpurchased pro rata
portion of the Offered Investor Shares.

     14.4   Offer Not Accepted

     If the Company and the accepting Series C Investors have not elected to
accept all of the Offered Shares pursuant to and within the time periods
specified above (maximum of 35 days), the Series C Investor may Transfer the
balance of the Offered Investor Shares to the prospective transferee named in
the statement attached to the Investor Offer as provided in Section 14.2, such
Transfer to be made only in strict accordance with the terms set forth in such
statement, and to be completed within thirty (30) days following the expiration
of the time provided for the election by the Series C Investors to accept the
Offered Shares, after which time any such Transfer shall again become subject to
all the restrictions of this Agreement.

     14.5   Transfers to Affiliates

     The restrictions on Transfers by the Series C Investors set forth in this
Section 14 shall not apply to Transfers by a Series C Investor to an affiliate
which controls, is controlled by, or under common control with such Series C
Investor provided that all such transferees shall simultaneously with such
Transfer execute this Agreement and become a party hereto and subject to the
provisions hereof.

     14.6   No Other Transfer Effective

     Except as provided in this Section 14, no Transfer in or to all or any part
of the capital stock of the Company now owned or hereafter acquired by the
Investors shall be effective, and the Company shall not record or recognize any
such Transfer, until there has been compliance with the provisions of this
Agreement.

     14.7   Termination of Restrictions

     The restrictions on Transfers by the Series C Investors set forth in this
Section 14 shall terminate upon the effective date of the Registration Statement
of the Company for the initial offering of its securities to the general public.

15.  Observer Rights

                                 Page 21 of 24
<PAGE>

     The Company shall permit the holders of a majority of the outstanding
Series C Preferred Stock to designate one (1) individual representative to
attend each meeting of the Company's Board of Directors and to participate in
all discussions during each such meeting (but not to vote on any matters). The
Company shall send to such representative notice of the time and place of each
meeting in the same manner and at the same time as it shall send such notice to
its directors and the Company shall also provide to the representative copies of
all notices, reports, minutes and consents at the time and in the manner as they
are provided to all directors; provided, however, that the Company reserves the
right to exclude such representative from any meeting or portion thereof, and
deny access to any materials, to the extent the Company believes that such
exclusion or denial of access is reasonably necessary to preserve the attorney-
client privilege, to protect confidential or proprietary information, material
non-public information or for other similar reasons. The representative
designated by the holders of the Series C Preferred Stock may designate a new
representative at any time and for any reason upon a written election by the
holders of a majority of the then outstanding Series C Preferred Stock. Such
representative shall not be deemed to be an officer or director of the Company
and shall not receive any direct or indirect compensation from the Company for
such activities. The observer rights contained herein shall terminate upon the
effective date of the Registration Statement of the Company for the initial
offering of its securities to the general public.

     In connection with an initial public offering of its securities to the
general public, the Company will nominate said representative as a member of the
Board of Directors, subject to applicable stockholder approval. If the Company
fails to complete an initial public offering within one hundred eighty (180)
days following the date hereof, the Company shall use its best efforts to obtain
the requisite approvals from the holders of the Series A Preferred Stock, the
Series B Preferred Stock, and the Common Stock pursuant to existing arrangements
between such stockholders and the Company for purposes of allowing the holders
of the Series C Preferred Stock to elect said individual to the Board of
Directors.
