OUR COMPANY

We develop, market and license natural input, electronic signature,
handwriting recognition and data security technologies and products for wireless
internet information devices and for the e-commerce, document information,
corporate security and other needs of businesses and individual users. Our
software products are designed to increase the ease of use, functionality and
security of electronic devices such as smart phones, electronic organizers and
portable web browsers.

Our natural input technology and products allow users to interact with a
computer or hand held device by using an electronic pen, either alone or in
conjunction with a keyboard. These products include Jot-Registered Trademark-
and the Handwriter-Registered Trademark- Recognition System, which are
multilingual handwriting recognition systems; INKshrINK-Registered Trademark-,
an ink compression system; QuickNotes-TM- and InkSnap-TM-, which facilitate
electronic note taking and drawing; and Word Complete-TM-, which simplifies data
entry tasks by reducing the number of letters that must be entered.

Our business solutions products are designed to provide a cost-effective
means for securing network and device access control, and electronic form
filing. These products include InkTools-TM-, which provides electronic ink
capture and display, signature capture and verification and ink compression
within computer applications, and PenX-TM- and PenX-TM-VC, which are operating
system extensions that enable the pen input data.

We have a four-pronged revenue generation strategy:

- OEM LICENSING. We license our products to original equipment
manufacturers, which are also called OEMs, such as Ericsson, Fujitsu,
Mitsubishi and National Semiconductor, and to independent software
vendors, which reproduce and market them in conjunction with their own
products.

- AFTERMARKET CONSUMER SALES. We generate consumer sales of our software
products through our website, www.cic.com. We utilize direct mail
programs, e-mail campaigns, pricing promotions and website enhancements to
generate sales. We also sell our products to consumers through on-line
resellers that include Digital River.com, Beyond.com, Handango.com,
Downloadwarehouse.com, Egghead.com, and Palmgear.com.

- ENTERPRISE SALES. We generate sales of our products to larger businesses
by leveraging our electronic signature software in emerging, fast-growth
areas such as e-commerce, document automation and corporate security
software applications. We make these sales through direct business
development and product sales activities in a number of
signature-dependent, vertical markets (such as financial services,
insurance, health care and real estate), and strategic partnerships.

- JOINT VENTURE IN CHINA. We provide systems integration services to
mainland Chinese governmental agencies and businesses, sell handwriting
recognition software to end-users and vendors, and license handwriting
recognition, electronic signature and other software for OEM sales in the
mainland Chinese market, through our joint venture in the People's
Republic of China.

RISK FACTORS

THE SHARES INVOLVE A HIGH DEGREE OF RISK. BEFORE MAKING AN INVESTMENT
DECISION, YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS, AS WELL AS
THE OTHER INFORMATION CONTAINED ELSEWHERE OR INCORPORATED BY REFERENCE IN THIS
PROSPECTUS.

WE HAVE A HISTORY OF LOSSES AND A SIGNIFICANT ACCUMULATED DEFICIT.

In each year since our inception, we have incurred losses, which for some
periods were significant. For the five-year period ended December 31, 2000,
those losses aggregated approximately $30 million, and at December 31, 2000 our
accumulated deficit was approximately $73 million. We may incur additional
losses in the future, and they could be substantial.

BECAUSE OF THE EMERGING NATURE OF THE PEN-BASED COMPUTING MARKET, IT IS
UNCERTAIN WHETHER OUR PRODUCTS WILL GAIN SIGNIFICANT MARKET ACCEPTANCE.

Our company develops, markets and licenses pen-based natural input,
electronic signature, handwriting recognition and data security technologies and
products for wireless internet information devices and for e-commerce, document
automation, corporate security and other businesses. The markets for pen-based
computing are relatively new. Because of the emerging nature of these markets we
are unable to predict whether we can sufficiently commercialize our products and
technology and obtain and retain significant market acceptance.

WE MAY NEED ADDITIONAL FINANCING AND, IF WE ARE UNABLE TO GET ADDITIONAL
FINANCING WHEN NEEDED, OUR BUSINESS WILL BE HARMED.

At June 30, 2001, our company's working capital was approximately
$4.3 million. We believe we have adequate capital to fund current operations for
the foreseeable future. However, we may need to obtain additional financing in
order to take advantage of potential opportunities or expand our operations.
Additional funds might not be available when needed or, if they are available,
we may not be able to obtain them on favorable terms. If adequate funds are not
available to us when needed, we may be required to delay, scale back or
eliminate some or all of our marketing and development efforts or our other
operations. This would have a material adverse effect on our business, operating
results and prospects.

IF WE ARE UNABLE TO CONTINUE TO DEVELOP NEW PRODUCTS AND MAKE ENHANCEMENTS ON
OUR EXISTING PRODUCTS IN A TIMELY AND COST-EFFECTIVE MANNER, OUR BUSINESS COULD
BE HARMED.

The markets in which our company competes are subject to rapid and
significant technological changes, the frequent introduction of new products and
product enhancements, and the development of new technologies. Our products and
underlying technologies are subject to these risks. If we are unable to develop
new products or technologies or enhance our existing products or technologies in
time to respond to market demands and technological changes, our business,
operating results and prospects could be materially and adversely affected.

OUR COMPETITORS COULD DEVELOP PRODUCTS OR TECHNOLOGIES THAT COULD MAKE OUR
PRODUCTS OR TECHNOLOGIES NON-COMPETITIVE.

The market for our products is intensely competitive and has attracted a
number of major companies that are well established in the software industry.
Some of our competitors have substantially greater financial and other resources
than we do. Our company faces competition at a number of different levels. Some
competitors have developed or are developing complete pen-based hardware and
software systems. Others have focused on different elements of those systems,
such as character recognition technology, pen-based operating systems and
environments, and pen-based

5
<Page>
applications. Some of our competitors could develop products or technologies
that are more effective, easier to use or less expensive than ours, such as
voice recognition. This could make our products and technologies obsolete or
non-competitive.

WE ARE DEPENDENT ON OUR DISTRIBUTORS AND STRATEGIC RELATIONSHIPS AND THE LOSS OF
ONE OR MORE OF THEM COULD HARM OUR BUSINESS.

Our company's ability to continue to commercialize its products and achieve
significant market acceptance depends in large part on our ability to continue
to develop licensing, marketing and other strategic relationships. Our strategic
partners generally do not have contractual commitments with us, and any one or
more of them could terminate their relationships with us. If this happens, or if
we are unable to establish additional strategic relationships, our business,
operating results and prospects would be materially adversely affected.

IF WE ARE UNABLE TO ADEQUATELY PROTECT OUR INTELLECTUAL PROPERTY, THIRD PARTIES
MAY BE ABLE TO USE OUR TECHNOLOGY, WHICH COULD ADVERSELY AFFECT OUR ABILITY TO
COMPETE IN THE MARKET.

We rely on a combination of patents, copyrights, trademarks, trade secrets
and contractual provisions to protect our proprietary rights in our products and
technologies. These protections might not be adequate. Moreover, our competitors
might independently develop technologies that are substantially equivalent or
superior to ours. The laws of some of the countries in which our products are
licensed do not protect those products and our intellectual property rights to
the same extent as the laws of the United States. Also, because of the rapid
evolution of technology and uncertainties in intellectual property law in the
United States and internationally, our current and future products and
technologies could be subject to infringement claims by others. We may be
required to take legal action to protect or defend our proprietary rights.

A substantial portion of our technology and know-how are trade secrets and
are not protected by patent, trademark or copyright laws. We require our
employees and contractors to execute written agreements that seek to protect our
proprietary information. We also have a policy of requiring prospective business
partners to enter into non-disclosure agreements before any of our proprietary
information is revealed to them. However, the measures taken by us to protect
our technology, products and other proprietary rights might not adequately
protect us against improper use.

LITIGATION OR THIRD-PARTY CLAIMS OF INTELLECTUAL PROPERTY INFRINGEMENT COULD
REQUIRE US TO SPEND SUBSTANTIAL TIME AND MONEY AND ADVERSELY AFFECT OUR ABILITY
TO DEVELOP AND COMMERCIALIZE PRODUCTS.

If we are required to defend against lawsuits brought by third parties, or
if we sue to protect our proprietary rights, we may be required to pay
substantial litigation costs, and our management and technical personnel's
attention may be diverted from operating our business. If the result of any
litigation is adverse to us, we may be required to expend significant resources
to develop non-infringing technology or obtain licenses from third parties. If
we are not successful in those efforts or if we are required to pay any
substantial litigation costs, our business would be materially and adversely
affected.

THERE ARE RISKS ASSOCIATED WITH OUR JOINT VENTURE IN THE PEOPLE'S REPUBLIC OF
CHINA.

Our company owns 90% of Communication Intelligence Computer
Corporation, Ltd., which is a joint venture between the Company and the
Information Industries Bureau of Jiangsu Province, a provincial agency of the
People's Republic of China. Our investment in the joint venture is subject to
the risks of doing business in China, including fluctuations in the value of
currencies, export duties, import controls and trade barriers (such as quotas),
restrictions on the transfer of funds, longer payment cycles, greater difficulty
in accounts receivable collections, burdens of complying with foreign

6
<Page>
laws and political and economic instability. Any of these risks or other risks
arising from doing business outside the United States can have a material
adverse effect on our company.

A SIGNIFICANT PORTION OF OUR SALES ARE DERIVED FROM A LIMITED NUMBER OF
CUSTOMERS, AND OUR BUSINESS MAY BE HARMED IF WE LOST ANY OF THESE CUSTOMERS.

Our revenues historically have been derived from a limited number of
customers. Therefore, the success of our business depends on our ability to
obtain customers and maintain satisfactory relationships with them in the
future. We may not be able to continue to maintain satisfactory relationships
with our customers in the future. Three customers accounted for 16%, 6% and 5%,
respectively, of our revenues in 2000. One customer accounted for approximately
27% of our revenues in 1999. The loss of any significant customer or other
revenue source would have a material adverse effect on our revenues and
profitability.

IF WE LOSE OUR KEY PERSONNEL OR ARE UNABLE TO ATTRACT AND RETAIN NEW PERSONNEL,
OUR OPERATIONS COULD BE DISRUPTED AND OUR BUSINESS WOULD BE HARMED.

We are highly dependent on the services of our management and key personnel.
The loss of the services of one or more of our executive officers or other key
persons could have a material adverse effect on the Company. We do not have
employment agreements with our executive officers or key personnel. Any one of
them may resign at any time and might organize a competitive business. Our
success also depends on our ability to attract and retain additional highly
skilled personnel. The competition for qualified personnel in the computer
industry is intense, and we might not be successful in attracting, retaining and
replacing personnel. Failing to attract and retain technical personnel could
adversely affect our research and development. Failing to attract and retain
management and other key personnel could adversely affect our sales and
marketing programs as well as the achievement of our goals.

THE MARKET PRICE OF OUR STOCK CAN BE VOLATILE, WHICH COULD RESULT IN LOSSES FOR
INVESTORS.

Our common stock is listed on The Nasdaq SmallCap Market. Stock prices of
technology companies in recent years have experienced significant volatility,
including price fluctuations that are unrelated or not proportional to the
operating performance of these companies. The market price of our common stock
has been and could be subject to significant fluctuations as a result of
variations in our operating results, announcements of technological innovations
or new products by us or our competitors, announcements of new strategic
relationships by us or our competitors, general conditions in the technology
industry or market conditions unrelated to our business and operating results.

FORWARD-LOOKING STATEMENTS

Certain statements contained in this registration statement, including
without limitation, statements containing the words "believes," "anticipates,"
"hopes," "intends," "expects," and other words of similar import, constitute

Litigation Reform Act of 1995. Such statements involve known and unknown risks,
uncertainties and other factors which may cause actual events to differ
materially from expectations. Such factors include the following:

- technological, engineering, quality control or other circumstances which
could delay the sale or shipment of products;

- economic, business, market and competitive conditions in the software
industry and technological innovations which could affect our business;

- our ability to protect our trade secrets or other proprietary rights,
operate without infringing upon the proprietary rights of others or
prevent others from infringing on our proprietary rights; and

- general economic and business conditions and the availability of
sufficient financing.

PLAN OF DISTRIBUTION

The Selling Shareholders may, from time to time, sell all or a portion of
the shares as follows:

- at prices and at terms then prevailing in the market;

- at prices related to the then current market price; or

- in negotiated transactions.

The shares may be sold by the Selling Shareholders in one or more of the
following ways, or others:

- block trades in which the broker or dealer so engaged will attempt to sell
the shares as agent but may position and resell a portion of the block as
principal to facilitate the transaction;

- purchases by a broker or dealer as principal and resale by the broker or
dealer for its account pursuant to this Prospectus;

- on a stock exchange in accordance with the rules of the particular
exchange;

- ordinary brokerage transactions and transactions in which the broker
solicits purchasers;

- privately negotiated transactions; or

- a combination of any of these methods of sale.

In effecting sales, brokers and dealers engaged by the Selling Shareholders
may arrange for other brokers or dealers to participate. Brokers or dealers may
receive commissions or discounts from the Selling Shareholders, or, if any
broker-dealer acts as agent for the purchaser of the shares, from the purchaser,
in amounts to be negotiated which are not expected to exceed those customary in
the types of transactions involved. Broker-dealers may agree with the Selling
Shareholders to sell a specified number of the shares at a stipulated price per
share, and, to the extent the broker-dealer is unable to do so acting as agent
for the Selling Shareholders, to purchase as principal any unsold shares at the
price required to fulfill the broker-dealer commitment to the Selling
Shareholders. Broker-dealers who acquire shares as principal may subsequently
resell the shares from time to time in the following transactions:

- transactions, which may involve block transactions and sales to and
through other broker-dealers, in the over-the-counter market or otherwise
at prices and on terms then prevailing at the time of sale;

- in negotiated transactions; or

- at prices related to the then-current market price.

In connection with these resales, the broker-dealer may pay to or receive
from the purchasers of the shares commissions as described above.

The Selling Shareholders and any broker-dealers or agents that participate
with the Selling Shareholders in sales of the shares may be deemed to be
"underwriters" within the meaning of the Securities Act in connection with any
sales. In the event of a sale, any commissions received by the broker-dealers or
agents and any profit on the resale of the shares purchased by them may be
deemed to be underwriting commissions or discounts under the Securities Act. In
addition, Regulation M under the Securities Exchange Act of 1934, as amended,
may apply in connection with the Selling Shareholders' sales of their shares.

We will pay all fees and expenses incident to the registration of the
shares. The Selling Shareholders will pay all commissions and discounts, if any,
attributable to the sales of the shares.
