    THIS SUMMARY HIGHLIGHTS SELECTED INFORMATION CONTAINED ELSEWHERE IN THIS
PROSPECTUS. THIS SUMMARY DOES NOT CONTAIN ALL OF THE INFORMATION THAT YOU SHOULD
CONSIDER BEFORE MAKING AN INVESTMENT DECISION. YOU SHOULD READ THE ENTIRE
PROSPECTUS, INCLUDING "RISK FACTORS" AND OUR FINANCIAL STATEMENTS AND RELATED
NOTES, BEFORE DECIDING TO INVEST.

                          INTERLINK ELECTRONICS, INC.

    We are a leader in the development of intuitive interface devices for a
variety of home and business applications. Our products for the home
entertainment and business communications markets enable a user to wirelessly
control and communicate with various products such as digital set-top boxes,
digital televisions, business presentation projectors and other electronic
products, which we refer to as appliances, by providing an intuitive device on
which the user can remotely input a variety of commands. In addition, our
electronic transactions product, EPAD, is a key component in providing a turnkey
electronic signature solution for the workflow automation and
business-to-business e-commerce markets, which we refer to collectively as the
e-transactions market. Our products incorporate our patented sensor and wireless
communications technologies and proprietary applications and ergonomic designs.

    While our strategy of using our collection of intuitive interface
technologies to create products for the home entertainment and e-transactions
markets is new, we are the leading supplier of intuitive interface devices and
components for the business presentation market, where we sell both to original
equipment manufacturers, or OEMs, and directly to consumers through reseller
channels. Our OEM customers include computer, computer peripheral and business
projector manufacturers, such as inFocus, Inc., Koninklijke Philips Electronics
N.V., NEC Corporation, Sharp Corporation, Sony Corporation and Toshiba
Corporation.

    In recent years, the number and types of computing, information and
entertainment appliances both in the home and in business have increased
dramatically. The convergence of television, computer technology and the
Internet has created the demand for interactive applications on both the
personal computer and the television. As a result, traditional interface
devices, such as standard button-based remote controls and keyboards, are no
longer intuitive or capable of interacting with more sophisticated applications.
Our solution is to develop products that enable users to communicate with, and
control, computers, televisions, business presentation projectors and other
complex electronic appliances. Our proprietary technologies allows us to offer
products with a number of benefits not available with traditional remote
controls, such as:

    - easy to use touchpad technology, which accepts finger or pen input and
      eliminates the need for button-based devices;

    - intuitive pad-to-screen mapping, which permits users to control an
      appliance without looking at our device and provides an on-screen
      "virtual" keyboard, but does not require the user to click or cursor
      through multiple menu items;

    - innovative gesture control, which allows users to input or write commands
      on a screen by touching and moving a finger or pen on a touchpad;

    - enhanced wireless communications technology that combines radio frequency,
      or RF, methodology with traditional infrared, or IR, to support high
      bandwidth applications and allow simultaneous and non-line-of-sight
      control of several appliances; and

    - functional and ergonomic designs that incorporate easy to use innovations
      such as our patented CLICKTRIGGER button.

    Businesses are seeking electronic signature solutions to facilitate
electronic commerce and automate business processes. However, there are few
cost-effective turnkey products commercially available, requiring businesses to
develop proprietary software and hardware solutions. Our solution is a product
that enables users to electronically sign documents necessary to conduct
e-transactions.

    Our strategy is to use our collection of technologies to become the leading
provider of intuitive interface devices for the home and business markets. The
principal elements of our strategy are as follows:

    - develop intuitive interface devices that are compatible with most home
      entertainment appliances and evolving technologies;

    - aggressively market our EPAD product to the e-transactions market for
      workflow automation and e-commerce applications;

    - maintain our leadership position in the business communications market;

    - develop proprietary applications to facilitate our entry into new markets;
      and

    - enhance our current technology and develop or acquire new technology and
      applications.

    A key component of our strategy to enter the home entertainment and
e-transactions markets is to establish, and expand existing, relationships with
our OEM customers and providers of complementary technologies. For example, we
are working with PSW Technologies Inc. to develop applications that can run on
our customers' home entertainment systems and be controlled by our products. In
the e-transactions market we are working with leading electronic signature
software developers such as Silanis Technology, Inc. and Communications
Intelligence Corporation, or CIC, to create turnkey electronic signature
solutions for end-users of our product. We also are establishing pilot programs
with large businesses to introduce our EPAD product to the workflow automation
market.

    We were incorporated in California in February 1985 and reincorporated in
Delaware in July 1996. The mailing address of our principal executive offices is
546 Flynn Road, Camarillo, California 93012 and our telephone number is
(805) 484-8855. We maintain a Website on the Internet at
"www.interlinkelectronics.com." Our Website and the information contained in it
are not a part of this prospectus.

                                  RISK FACTORS

    YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED BELOW, TOGETHER WITH ALL
OF THE OTHER INFORMATION INCLUDED IN OR INCORPORATED BY REFERENCE INTO THIS
PROSPECTUS, BEFORE MAKING AN INVESTMENT DECISION. THE RISKS AND UNCERTAINTIES
DESCRIBED BELOW ARE NOT THE ONLY ONES WE FACE. IF ANY OF THE FOLLOWING RISKS
ACTUALLY OCCUR, OUR BUSINESS COULD BE HARMED. IN SUCH CASE, THE TRADING PRICE OF
OUR COMMON STOCK COULD DECLINE, AND YOU MAY LOSE ALL OR PART OF YOUR INVESTMENT.

                 RISKS RELATING TO OUR FUTURE FINANCIAL RESULTS

OUR NEW BUSINESS PLAN IS BASED ON ASSUMPTIONS THAT COULD PROVE TO BE INCORRECT,
IN WHICH CASE OUR BUSINESS, RESULTS OF OPERATIONS AND FINANCIAL CONDITIONS COULD
BE ADVERSELY AFFECTED.

    A key element of our new business plan involves the expansion of our product
lines to serve what we expect to be growing new markets in the home
entertainment and e-transactions sectors. The success of our new plan depends on
numerous assumptions that we cannot be sure are justified. If any of our key
assumptions are incorrect, we could be unable to expand our business as we
currently anticipate and we may make substantial investments in product
development and marketing efforts that do not result in new product sales. Our
assumptions include the following:

    - demand for intuitive interface devices in the home entertainment and
      e-transactions markets will increase rapidly;

    - our technology will adequately address market needs as they develop;

    - other companies with whom we have or may develop relationships will be
      successful in developing their technologies and addressing their markets;

    - other companies will not develop competing technologies that offer
      substantial technological or economic advantages over ours; and

    - industry standards will be adopted based on technologies with which our
      products can be made compatible.

    Our historical financial information does not reflect our new business
strategy in the home entertainment or e-transactions markets, which may make it
difficult to predict our actual results in future periods. Our historical
financial information reflects the results of operations related almost
exclusively to our business communication and specialty products markets, which
accounted for 63% and 31%, respectively, of our 1999 sales. While we expect
these businesses to continue as important contributors to our future financial
performance, we expect future financial results to be significantly impacted by
the results of our contemplated activities in the home entertainment and
e-transactions markets. We have no internal historical data on which to base any
forecast with respect to this performance. Because both of these markets are
new, we and you are also unable to rely on historical results of other companies
in those markets. The actual results of our future operations may differ
materially from our anticipated results and may fail to justify the investment
we expect to make in developing those markets.

WE ARE UNABLE TO PREDICT THE AMOUNT OR TIMING OF GROWTH IN MARKETS WHERE WE
EXPECT MOST OF OUR FUTURE REVENUE GROWTH TO OCCUR, WHICH COULD RESULT IN
SUBSTANTIALLY REDUCED EARNINGS OR LOSSES.

    Because the home entertainment and e-transactions markets are new and
rapidly changing, we cannot predict the future characteristics of these markets,
including their ultimate size or the amount of time that will be required to
achieve the growth on which our new business plan is based. As a result, we may
time our own investment of resources to address these markets in a way which
either fails to meet actual demand or results in expenses that we cannot justify
in light of actual sales volume. A failure to meet actual demand could put us at
a competitive disadvantage, while an investment in

                                       7
<PAGE>
markets that develop more slowly than anticipated could result in substantially
reduced earnings or losses. We cannot assure you that we will be able accurately
to forecast market demand in time to respond appropriately.

OUR OPERATING RESULTS ARE EXPECTED TO CONTINUE TO FLUCTUATE, WHICH MAY CAUSE THE
PRICE OF OUR COMMON STOCK TO DECLINE.

    Our future quarterly and annual operating results are subject to
fluctuations due to a wide variety of factors, including:

    - the cyclicality of the home entertainment and e-transactions markets;

    - declines in average selling prices of our products;

    - oversupply of products on the market;

    - our failure to introduce new products and to implement technologies on a
      timely basis;

    - market acceptance of our and our customers' products;

    - failure to anticipate changing customer product requirements;

    - fluctuations in manufacturing yields;

    - failure to deliver products on a timely basis;

    - disruption in the assembly services;

    - changes in product mix;

    - timing of significant orders;

    - increased expenses associated with new product introductions or
      manufacturing changes; and

    - the ability of customers to make payments to us.

OUR SALES MAY BE CONCENTRATED WITH ONE OR MORE CUSTOMERS OR IN LIMITED MARKET OR
GEOGRAPHIC AREAS, WHICH COULD MAKE FLUCTUATIONS IN REVENUE AND EARNINGS MORE
SEVERE.

    Three customers accounted for approximately 14%, 12% and 11% of our 1999
sales. Approximately 63% of our sales were to our business communication
customers and approximately 50% of our sales were to customers in Japan. There
are a relatively limited number of OEMs that make business presentation products
and we sell to many of them. The loss of a significant customer could have a
material adverse impact on our sales and earnings. While we expect overall
market size in the home entertainment and e-transactions markets to grow, it
remains possible that significant penetration of these markets may depend on
large volume sales to a limited number of potential customers. Concentration in
our customer base may make fluctuations in revenue and earnings more severe and
make business planning more difficult.

OUR NEW BUSINESS STRATEGY OF DEVELOPING PRODUCTS FOR THE HOME ENTERTAINMENT AND
E-TRANSACTIONS MARKETS MAY NOT BE SUCCESSFULLY IMPLEMENTED BY US, AND IT IS
DIFFICULT TO EVALUATE OUR STRATEGY BECAUSE IT IS NEW AND UNPROVEN.

    We have only recently begun to implement our new business strategy of
developing products for the home entertainment and e-transactions markets, and
we do not have an operating history with this new strategy upon which you can
evaluate our prospects. In attempting to implement our new strategy, we are
significantly changing our product development and marketing practices and
management focus. We are also facing new risks and challenges, including a lack
of meaningful historical financial data on which to plan future budgets, the
need to develop new strategic relationships and other risks described

                                       8
<PAGE>
in this prospectus. Our operating history is not indicative of our future
performance under our new business strategy, and you should not rely on our past
performance to predict our future performance. We may not be able to implement
our new business strategy successfully.

WE HAVE NO SIGNIFICANT BACKLOG OF ORDERS IN OUR NEW HOME ENTERTAINMENT AND
E-TRANSACTIONS BUSINESSES.

    Although our new business plan anticipates substantial growth in the home
entertainment and e-transactions markets in the future, we currently have no
significant backlog of orders from these markets. In particular, in the home
entertainment market, significant orders will depend not only on customer
acceptance of our products but on customer product design schedules for upgrades
to their own products that will permit our products to function together. We
cannot assure you that we will develop a significant e-transactions order
backlog in the near future and we do not expect a significant home entertainment
order backlog until at least 2002.

INTERNATIONAL SALES AND MANUFACTURING RISKS COULD ADVERSELY AFFECT OUR OPERATING
RESULTS.

    Our reliance on international sales and manufacturing exposes our business
to several risks that are not generally encountered in domestic operations. Our
revenue from international sales accounted for approximately 39%, 70% and 69% of
net sales for 1997, 1998 and 1999, respectively. Substantially all of these
sales were to customers in Japan. Accordingly, our future operating results will
also depend on general economic conditions in Asia and our other markets. In
addition, the markets for our products, which are cyclical, may not continue to
grow. We anticipate that sales to international customers will continue to
represent a significant percentage of our net sales. Moreover, our large volume
non-Force Sensing Resistor manufacturing is currently performed by contractors
in Asia. The manufacture and sale of products in foreign countries involves a
number of risks relating to international trade transactions, local business
practices and cultural considerations, including:

    - economic conditions in the countries in which manufacturing or sales
      occur, including Japan and China;

    - changes in trade policy and regulatory requirements;

    - duties, tariffs and other trade barriers and restrictions;

    - the burdens of complying with foreign laws;

    - foreign collection fluctuations; and

    - political and transportation risks.

Any of the above factors could, in the future, result in a material decrease in
revenue and disrupt the supply of components from foreign markets.

OUR OPERATING RESULTS COULD BE ADVERSELY AFFECTED BY FLUCTUATIONS IN THE VALUE
OF FOREIGN CURRENCIES.

    International sales made through our Japanese subsidiary are generally
denominated in yen. A weak yen would adversely affect total revenue and could
result in a decrease in dollar revenue even though sales remained constant or
increased. We also contract for most of our large-volume, non-FSR manufacturing
in China. Although we contract in U.S. dollars, a weakening of the dollar could
cause existing contracts to be uneconomical to the vendor and, therefore,
require a renegotiation. Over the past two years, the valuations of many foreign
currencies have fluctuated significantly relative to the U.S. dollar. The
Japanese yen, in particular, has fluctuated in value due in part to the economic
problems experienced by Asian countries. Although we engage in currency hedging
transactions in order to mitigate the risks of currency fluctuations, we cannot
assure you that these activities will protect us from such risks.

                                       9

ANY INDUSTRY DOWNTURN IN THE MARKETS WE SERVE WOULD HARM OUR BUSINESS.

    A majority of our current products are incorporated into products such as
remote controls and medical devices. These markets have from time-to-time
experienced cyclical, depressed business conditions, often in connection with,
or in anticipation of, a decline in general economic conditions. Such industry
downturns have resulted in reduced product demand and declining average selling
prices. Our business would be harmed by any future downturns in the markets that
we serve.

                         RISKS RELATING TO OUR BUSINESS

WE MAY NOT BE ABLE TO DEVELOP AND INTRODUCE NEW PRODUCTS TO RESPOND TO EVOLVING
INDUSTRY REQUIREMENTS IN A TIMELY MANNER.

    Technology, both in our markets and in our customers' markets, is undergoing
rapid change. In order to maintain our leadership position in our existing
markets and to emerge as a leader in new markets, we will have to maintain a
leadership position in the technologies supporting those markets. Doing so will
require, among other things, that we undertake the following:

    - accurately predict the evolving needs of our customers and develop, in a
      timely manner, the technology required to support those needs;

    - provide products that are not only technologically sophisticated but are
      also available at prices within consumer tolerances and competitive with
      comparable products;

    - establish and effectively defend our ownership of the intellectual
      property supporting our products; and

    - enter into relationships with other companies that have developed
      complementary technology on which our products also depend.

We cannot assure you that we will be able to achieve any of these objectives.

IF THE HOME ENTERTAINMENT AND E-TRANSACTIONS MARKETS DO NOT ADOPT OUR
TECHNOLOGY, OUR BUSINESS MAY BE ADVERSELY AFFECTED.

    Our business strategy is to develop intuitive interface devices for the home
entertainment and e-transactions markets. These devices will be based on our
proprietary FORCE SENSING RESISTOR, or FSR, and REMOTELINK technologies. If the
home entertainment and e-transactions markets do not adopt these technologies,
or other technologies we develop, our ability to sell products to these markets
would be adversely affected. Alternatives to FSRs, such as strain gauges, piezo
sensors and conductive rubber, and to REMOTELINK, such as traditional infrared
or Bluetooth-TM-, could offer cost and performance advantages to OEMs that
compete in those markets. We cannot assure you that our products or technologies
will be adopted by significant segments of these markets, or at all.

OUR MARKETS ARE INTENSELY COMPETITIVE AND MANY OF OUR POTENTIAL COMPETITORS HAVE
RESOURCES THAT EXCEED OUR OWN.

    Each of the markets in which we compete is intensely competitive and has
been characterized by price erosion, rapid technological change, short product
life cycles, cyclical market patterns and heightened foreign and domestic
competition. Competition is based on technology, established relationships,
quality of support and price, and the business presentation interface market is
relatively small at the present time. We expect that the home entertainment and
e-transactions markets will be much larger and are likely to attract more
intense competition. Many of our competitors and potential competitors offer
broader product lines and have greater technological, financial, marketing,
established business relationships and other resources that may afford them a
competitive advantage.

                                       10
<PAGE>
    We may not be able to compete successfully against any of these competitors.
Our ability to compete successfully in the home entertainment and e-transactions
markets depends on factors both within and outside of our control, including:

    - the rate at which OEM customers incorporate our products into their
      systems;

    - the success of our customers' products;

    - product pricing;

    - access to advanced process technologies at competitive prices;

    - product functionality, performance and reliability;

    - successful and timely product development;

    - the gain or loss of significant customers; and

    - the nature of our competitors and general economic conditions.

    In addition, we are vulnerable to technology advances utilized by
competitors to manufacture higher performance or lower cost products. We may not
be able to compete successfully in these or other areas of our business.

A FAILURE TO ATTRACT AND RETAIN QUALIFIED INDIVIDUALS FOR CRITICAL POSITIONS
COULD HAVE AN ADVERSE IMPACT ON OUR BUSINESS, FINANCIAL CONDITION AND RESULTS OF
OPERATIONS.

    Our success is substantially dependent on the continued availability of our
key management and technical personnel, including the employees listed in the
"Management" section of this prospectus. Several of our key management personnel
have been with us throughout most of our history and have substantial experience
with our business and technology. If one or more of our key employees are no
longer available to us and we are unable to find a replacement with the
combination of skills and attributes necessary to execute our new business plan,
we may be unable to execute our new plan successfully. Our success will also
depend, in part, on our ability to attract and retain qualified professional,
technical, production, managerial and marketing personnel, both domestically and
internationally. Competition for such personnel in our industry is intense.
While we have not yet experienced significant problems in recruiting or
retaining qualified personnel, we cannot be certain that such problems will not
arise in the future.

FAILURE TO MANAGE OUR GROWTH EFFECTIVELY COULD HAVE A SIGNIFICANT NEGATIVE
IMPACT ON OUR OPERATIONS.

    We will need to expand our operations rapidly if we achieve acceptance of
our products in the home entertainment and e-transactions markets. Difficulties
in managing our future growth could have a significant negative impact on our
business operations, increase our costs and make it difficult for us to maintain
profitability. We may not be able to project the rate or timing of increases in
orders for our products accurately, or to expand and upgrade our engineering,
sales and manufacturing systems and infrastructure to accommodate these
increases. Our future results of operations will depend on the ability of our
officers and key employees to manage changing business conditions and to
implement and improve our technical, administrative, financial control and
reporting systems in response to our anticipated rapid growth.

WE MAY BE UNABLE TO OVERCOME PRICE ADVANTAGES OF LOW-COST REMOTE PRODUCTS.

    Our intuitive interface devices typically cost substantially more than the
traditional, button-operated remote controls. While we believe that our products
offer numerous advantages compared to traditional remote controls, we cannot
assure you that our customers or end-users in our targeted home and business
markets will consider these advantages to be worth the cost difference. We are
not a

                                       11
<PAGE>
low-cost provider of low-technology products and are therefore dependent on
market acceptance of our pricing structure based on the technological advantages
of our products.

FUTURE STANDARDS OR REGULATIONS MAY ADVERSELY AFFECT THE MARKETABILITY OF OUR
PRODUCTS.

    If a standard is developed or a regulation implemented that our products do
not easily support or comply with, our competitive position could be adversely
affected. Our products are designed to provide the interface between the user
and a variety of electronic devices. Many of these devices are rapidly evolving
both in functionality and in the technology supporting that functionality. As a
result, various associations or groups of manufacturers of these products may
seek to establish communication protocols and other industry standards and
incorporate these standards into their product designs. Our technology may not
be well suited to support these standards. Alternatively, we may design products
based on assumptions as to what the prevailing standard will ultimately be that
turn out to be false.

WE RELY ON OTHERS FOR SIGNIFICANT ASPECTS OF OUR MANUFACTURING AND ANY
INTERRUPTION OF THESE ARRANGEMENTS COULD ADVERSELY IMPACT OUR BUSINESS.

    We contract for substantially all of our high volume product manufacturing,
other than the manufacturing of FSR sensors. The bulk of our contract
manufacturing is currently done by two manufacturing companies in China. An
interruption in our current manufacturing arrangements would have an adverse
impact on our business.

AN INTERRUPTION IN THE SUPPLY OF ANY SIGNIFICANT FSR SENSOR OR OTHER COMPONENT
COULD CAUSE US TO MISS SHIPMENT DEADLINES, WHICH COULD REDUCE REVENUE IN THE
SHORT-TERM AND ADVERSELY AFFECT OUR CUSTOMER RELATIONSHIPS IN THE LONG-TERM.

    We use various semiconductor chips in conjunction with our FSR sensors and
other product components. From time to time, the semiconductor industry has
experienced capacity constraints and we have, in the past, occasionally had
difficulty obtaining an adequate supply of semiconductor chips. Some of the
other components of our products have been or are expected to be custom designed
for our use and are or will be available only from the vendors with whom we have
contracted to supply them. An interruption in the supply of any significant
component could cause us to miss shipment deadlines, which could reduce revenue
in the short-term and adversely affect our customer relationships in the
long-term.

PERFORMANCE, RELIABILITY OR QUALITY PROBLEMS WITH OUR PRODUCTS MAY CAUSE OUR
CUSTOMERS TO REDUCE OR CANCEL ORDERS.

    Our products are technologically complex and we regularly introduce new
products incorporating new technologies or manufacturing processes.
Notwithstanding our quality assurance procedures, we have in the past
experienced performance, reliability or quality problems with our products and
anticipate that such problems may occur from time to time in the future. This
could result in a delay in recognition or loss of revenues, loss of market share
or failure to achieve market acceptance. These defects may also cause us to
incur significant warranty support and repair costs, divert the attention of our
engineering personnel from our product development efforts and harm our
relationships with customers. The occurrence of these problems could result in
the delay or loss of market acceptance of our products and would likely harm our
business. Defects, integration issues or other performance problems in our
products could result in financial or other damages to our customers or could
lessen market acceptance of our products. Our customers could also seek damages
from us for their losses. A product liability claim brought against us, even if
unsuccessful, would likely be time-consuming and costly to defend.

                                       12
<PAGE>
FEDERAL, STATE AND INTERNATIONAL LEGISLATION AND REGULATION AFFECTING E-COMMERCE
COULD ADVERSELY AFFECT OUR ABILITY TO IMPLEMENT OUR NEW BUSINESS STRATEGY.

    Our ability to market intuitive interface devices may be subject to federal,
state and foreign laws and regulations affecting e-commerce. Existing and new
laws and regulations applicable to e-commerce could have an adverse effect on
our ability to market products and applications for use in e-commerce. Although
many states have enacted legislation regulating electronic signatures, for
example, state laws differ widely on the need for related encryption technology
and how they address allocation of liability relating to the use of
electronically signed documents. Legislation governing electronic signatures is
pending before Congress. It may be expensive to implement measures designed to
comply with any new legislation. Moreover, if the authenticity of electronic
signatures is not protected by applicable law, the marketability of our EPAD
product may be adversely affected.

WE ARE SUBJECT TO RISKS ASSOCIATED WITH MANUFACTURING CERTAIN OF OUR PRODUCTS AT
A SINGLE FACILITY.

    We manufacture our FSRs at our facility in Camarillo, California. This
manufacturing operation requires sophisticated equipment and a specially
designed facility. As a result, any prolonged disruption in the operations of
our manufacturing facility, whether due to technical or labor difficulties,
destruction of or damage to this facility as a result of an earthquake, fire or
any other reason, could have an adverse effect on our business, financial
condition or results of operations.

                          RISKS RELATING TO TECHNOLOGY

IF WE ARE NOT ABLE TO PROTECT OUR INTELLECTUAL PROPERTY OR IF WE INFRINGE ON THE
INTELLECTUAL PROPERTY OF OTHERS, OUR BUSINESS AND OPERATING RESULTS COULD BE
ADVERSELY AFFECTED.

    We consider our intellectual property portfolio to be a key element of our
ability to compete in our chosen markets. We rely on a combination of patents,
trade secrets and contractual restrictions in our agreements with our product
development partners and vendors to establish and protect our intellectual
property rights. We cannot assure you that patents will be issued in response to
our pending applications or that any claims allowed from existing or pending
patents will be sufficiently broad to protect our technology. In addition, we
cannot assure you that any patents issued to us will not be challenged,
invalidated or circumvented, or that the rights granted will provide proprietary
protection. If it appears necessary or desirable, we may seek licenses under
patents that we are alleged to be infringing. Although a patent holder may offer
us a license, they may not be offered and the terms of any offered licenses may
not be acceptable to us. Litigation may be necessary to enforce our patents,
trade secrets and other intellectual property rights, to determine the validity
and scope of the proprietary rights of others or to defend against claims of
infringement. Such litigation could result in substantial costs and diversion of
resources and could have a material adverse effect on our business, regardless
of the final outcome of the litigation.

    We are not currently engaged in any patent infringement suits, however, we
have been threatened with one such suit in recent years. Despite our efforts to
maintain and safeguard our proprietary rights, we cannot assure you that we will
be successful in doing so or that our competitors will not independently develop
or patent technologies that are substantially equivalent or superior to our
technologies. If any of the holders of these patents assert claims that we are
infringing on their alleged rights, we could be forced to incur substantial
litigation expenses or to pay substantial royalties and to suspend the
manufacture or sale of products using the invention or to attempt to develop
non-infringing products, any of which could adversely affect our business and
operating results. In addition, if we were found to infringe, we could be
required to pay substantial damages, pay royalties in the future and be enjoined
from infringing in the future.

                                       13
<PAGE>
    Our employees and others who may come to know our trade secrets may use them
improperly or disclose them to others. In such cases, we may not know that our
trade secrets are being misused and, if we do know, we may be unable to take
effective action to prevent the misuse.

OUR COMPETITORS MAY HAVE PROPRIETARY TECHNOLOGIES WHICH CREATE BARRIERS TO
ENTRY.

    Our markets are competitive and many other companies may be developing
technologies that they believe will permit them to compete in those markets.
Such technologies, if successfully developed, may be technically superior to
ours or, whether or not they are technically superior, may set an industry
standard that will define the successful product for that market. We may be
unable to compete against such technologies or to acquire the right to
incorporate them in our products on commercially reasonable terms or at all.

ADOPTION OF TECHNOLOGIES AND STANDARDS BY ELECTRONICS MANUFACTURERS AND SERVICE
PROVIDERS ARE DIFFICULT TO PREDICT.

    Our intuitive interface devices must work with the appliances they control.
These appliances are controlled by computer programs developed by their
manufacturers and by service providers such as cable and satellite system
operators and telephone companies. It may be difficult to predict the technology
choices these companies will make and on which the compatibility of our products
will depend. Although we are forming relationships with manufacturers and
service providers in the home entertainment market, we may not be able to
convince them to create programs that are compatible with our products.
Moreover, a competitor with a close working relationship with these companies
may obtain advance knowledge of such choices or may be afforded an opportunity
to work in partnership to develop compatible technologies and may, therefore,
achieve a competitive advantage.

WE RELY ON OTHERS FOR SIGNIFICANT ASPECTS OF OUR TECHNOLOGY DEVELOPMENT.

    Our in-house research and development expertise is focused on our sensor and
communication technologies. We do not currently have significant expertise in
software development, chip design or other critical technological aspects of a
complete product. We rely on other companies with whom we may contract or enter
into joint development agreements to provide these aspects of our product
technologies. For example, we are currently relying on PSW Technologies Inc. to
develop certain software enabling the use of our home entertainment product with
digital set-top boxes and on a contract software company in India to produce
software critical to the operation of our EPAD product. We expect to enter into
similar arrangements in the future. We cannot assure you that we will be able to
contract or otherwise arrange for these services in the future. We also cannot
assure you that a developer with whom we contract for technology will not use or

              RISKS RELATING TO AN INVESTMENT IN OUR COMMON STOCK

OUR STOCK PRICE HAS BEEN VOLATILE AND COULD DECLINE SIGNIFICANTLY.

    The price of our common stock has been subject to significant volatility and
the market price of our common stock has recently increased substantially,
having traded as low as $2.67 on a split-adjusted basis in January 1999. Many of
the factors that may affect the value of our stock are unrelated to our
financial performance or prospects, including macroeconomic developments in the
United States and globally and market perceptions of the attractiveness of
particular industries. Our stock price is also likely to be significantly
affected by short-term changes in our financial condition or results of
operations as reflected in our quarterly earnings reports. As a result, the
market price of our stock at any given point in time may not accurately reflect
our long-term value. Securities class action litigation often has been brought
against companies following periods of volatility in the market price of their

                                       14
<PAGE>
securities. We may in the future be the target of similar litigation. Securities
litigation could result in substantial costs and damages and divert management's
attention and resources.

FUTURE SALES OF OUR COMMON STOCK MAY CAUSE OUR STOCK PRICE TO DECLINE.

    All of our outstanding shares are freely tradable without restriction or
future registration. Affiliates must sell all shares they own in compliance with
the volume and other requirements of Rule 144, except for the holding period
requirements. Our officers and directors have agreed that for a period of
90 days after the date of this prospectus, they will not directly or indirectly
sell any shares of common stock without the prior written consent of Banc of
America Securities LLC. Sales of substantial amounts of common stock by our
stockholders may have a depressive effect on the market price of our common
stock and could impair our ability to raise capital through the sale of our
equity securities.

YOU WILL BE RELYING ON OUR JUDGMENT REGARDING OUR USE OF PROCEEDS.

    With the exception of $10 to $15 million that we expect to use to develop
and market products for use in the home entertainment and e-transactions
markets, we have not designated any specific use for the net proceeds from our
sale of common stock described in this prospectus. Rather, we expect to use most
of the net proceeds for working capital, capital expenditures, general corporate
purposes and, possibly, acquisitions of technology or businesses. We will have
significant flexibility in applying the net proceeds of this offering and our
other cash resources. You will be relying on our judgment regarding the
application of our resources, including the net proceeds of this offering. We
will have the ability to change the application of the net proceeds from this
offering without stockholder approval.

WE MAY ENGAGE IN BUSINESS COMBINATIONS THAT MAY DILUTE STOCKHOLDERS, DIVERT
MANAGEMENT'S ATTENTION, OR CAUSE INTEGRATION DIFFICULTIES.

    We may elect to pursue our growth strategy by acquiring or combining with
other businesses. Such combinations may be structured as stock or cash
transactions or as a combination of the two. Business combinations are extremely
time-consuming and expensive and there is no guaranty that any given combination
will be completed. In addition, business combinations can cause substantial
dilution in the investment of the existing stockholders and can result in a
significant drop in our stock price if market perceptions of the combination are
not favorable. Following a combination, it is necessary to integrate the two
businesses, which is always time-consuming and often difficult. Many business
combinations are a result of intensely competitive bidding and we may find
ourselves under severe pressure to increase our bid for a particular business.
For financing or legal reasons, we may be required to divest ourselves of
certain assets in order to consummate a business combination or to increase
leverage by borrowing. We cannot assure you that any business combination we may
attempt to consummate will have a positive effect on our business or financial
condition.

DELAWARE LAW RESTRICTS THE ABILITY OF SOME STOCKHOLDERS TO ENTER INTO BUSINESS
COMBINATIONS WITH OUR COMPANY WITHOUT THE CONSENT OF THE BOARD OF DIRECTORS.

    The Delaware anti-takeover law restricts business combinations with some
stockholders once the stockholder acquires 15% or more of our common stock. The
Delaware statute makes it harder for our company to be acquired without the
consent of our board of directors and management.

                           FORWARD-LOOKING STATEMENTS

    This prospectus, including, without limitation, the "Prospectus Summary,"
"Risk Factors," "Use of Proceeds," "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Business," contains
statements that constitute "forward-looking statements" within the meaning of
section 27A of the Securities Act of 1933 and section 21E of the Securities
Exchange Act of 1934. These forward-looking statements involve a number of risks
and uncertainties. The following, in addition to the risk factors described
above, are among the factors that could cause actual results to differ
materially from the forward-looking statements: growth of, and our ability to
market products to, the home entertainment and e-transactions markets; an
unexpected change in business conditions or a slowdown in growth in the
electronics industry and general economies, both domestic and international;
lower than expected customer orders, delays in receipt of orders or cancellation
of orders; competitive factors, including increased competition, new product
offerings by competitors and price pressures; limitations on the availability of
third party parts and supplies at reasonable prices; changes in product mix;
significant quarterly performance fluctuations due to the receipt of a
significant portion of customer orders and product shipments in the last month
of each quarter; and product shipment interruptions due to manufacturing
problems. The forward-looking statements contained in this prospectus regarding
industry trends, revenue and product mix, costs and gross profit expectations,
product development costs, operating expense improvements, cash flow, foreign
currency exchange risk and future business activities should be considered in
light of these factors.

                                USE OF PROCEEDS

    The net proceeds from the sale of the 2,143,512 shares of common stock
offered by Interlink are estimated to be $119.4 million at an assumed public
offering price of $59.71 per share, after deducting underwriting discounts and
commissions and estimated offering expenses ($131.3 million if the
over-allotment option is exercised in full).

    We expect to use the net proceeds from this offering for working capital and
general corporate purposes. We also expect to use approximately $10 to
15 million of the net proceeds for marketing to potential customers in, and
developing products for use in, the home entertainment and e-transactions
markets. In addition, Interlink may use a portion of the net proceeds to acquire
complementary technologies or businesses; however, we currently have no
commitments or agreements relating to such acquisitions. We have not yet
determined with any certainty the manner in which we will allocate the net
proceeds. The amounts and timing of these expenditures will vary depending on a
number of factors, including the amount of cash generated by our operations,
competitive and technological developments and the rate of growth, if any, of
our business. We will not receive any proceeds from the shares sold by the
selling stockholders in this offering, including any shares sold if the
underwriters exercise their option in full. Pending use of the net proceeds of
this offering, Interlink intends to invest the net proceeds in interest-bearing,
investment-grade securities. Our board of directors has broad discretion in
determining how the net proceeds of this offering will be applied.

                                DIVIDEND POLICY

    We have never declared or paid cash dividends on our common stock. Payment
of any cash dividends will depend on the results of our operations, our
financial condition and our capital expenditure plans, as well as other factors
our board of directors may consider relevant. We presently intend to retain any
earnings for use in our business and, therefore, do not anticipate paying any
cash dividends in the foreseeable future.

                                    DILUTION

    Our net tangible book value as of December 31, 1999 was approximately
$17,965,000 or $2.10 per share. Net tangible book value per share represents the
amount of our total tangible assets less total liabilities, divided by the total
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 2,143,512 shares of common stock offered by this
prospectus and after deducting the underwriting discounts and commissions and
estimated offering expenses payable by us, our as adjusted net tangible book
value would have been approximately $137,391,000, or approximately $12.84 per
share. This represents an immediate increase in net tangible book value of
$10.74 per share to existing shareholders and an immediate dilution in net
tangible book value of $46.87 per share to new investors.

    These tables exclude all options that will remain outstanding upon
completion of this offering and does not consider shares that will be sold in
this offering by existing stockholders. See note 7 of the notes to the
consolidated financial statements for information or options. The exercise of
outstanding options having an exercise price less than the offering price would
increase the dilutive effect to new investors.

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

OVERVIEW

    We are a leader in the development of intuitive interface devices for a
variety of home and business applications. We were incorporated in California in
February 1985 and reincorporated in Delaware in July 1996. From 1985 to 1993, we
developed and refined our FORCE SENSING RESISTOR, or FSR, technology and sold it
to customers for electronic, musical, medical and other applications, which we
now refer to as the specialty components market. In 1992, we introduced our
first branded computer pointing device, PORTAPOINT, and in 1994, we introduced
our first wireless pointing device, REMOTEPOINT. With the advent of this latter
device, we established ourselves as a leading supplier to OEMs in the
computerized presentation system market, which we now call the business
communication market. In 1999, we introduced products for e-transactions
applications and began developing products for the home entertainment market.

    Revenue, net of allowances for returns and warranty, is recognized upon
shipment of product. Royalty revenue is recorded when earned. Revenues have
increased steadily during the last five years as we have established ourselves
in new markets and built a base of OEM customers in the computer and computer
peripheral industry. Gross profit as a percentage of revenues declined between
1995 and 1997 as a result of the increasing percentage of our business that
involved sales of computer products to OEMs but has remained relatively steady
over the last three years. Product development and research expenditures, which
includes engineering, contract engineering and development and material costs of
development, have generally increased as revenue has increased but has remained
relatively consistent as a percentage of revenues, reflecting our continuing
commitment to the technological and design innovation required to maintain a
leadership position in existing markets and to develop new ones. Selling,
general and administrative expense, which includes sales, marketing and
administrative personnel, advertising, sales commissions, reseller incentives,
tradeshow costs and other sales expenses, has declined each year as a percentage
of sales, reflecting the amortization of a relatively fixed expense requirement
over a larger revenue base. Because of net operating loss carryforwards
available both for our U.S.-based and Japan-based operations, we historically
have not paid income tax. Beginning in 1999, some of these loss carryforwards
began to expire or become fully utilized; therefore income taxes are expected to
increase on both a percentage and absolute dollar basis. Other income (expense)
was significant in 1998 as the result of a non-recurring legal settlement
expense.

    Prior to 1999, operations was a net user of cash and we funded this through
existing cash balances, private placements of equity and to a lesser extent,
bank and lease financing. In 1999, operations was a net provider of cash,
generating $2.9 million.

    Sales of business communication intuitive interface devices accounted for
63% of our total sales in 1999 and 60% of our total sales in the three years
ended December 31, 1999. Our business communication sales in dollars grew at an
average annualized rate of 31% in 1999. Because our market share for business
communication interface devices is approximately 80%, we expect that our ability
to achieve further revenue growth in this market will largely depend on growth
in the market itself.

    We have established relationships with most of the major OEMs in the
business communication market. Many of these OEMs are based in Japan and
approximately 50% of our 1999 revenues came from Japanese customers. As a result
we are subject to foreign currency exchange rate fluctuations, primarily in the
yen/dollar exchange rate.

    We have licensed certain technology related to the production of FSR sensors
to International Electronics and Engineering, a former affiliate based in
Luxembourg, for use in connection with sales of sensors to the automotive
industry. We are entitled to royalties in connection with sales of automotive
sensors outside Europe. Royalties earned in 1999 approximated $580,000. We have

                                       21
<PAGE>
occasionally licensed other aspects of our technology in connection with the
settlement of intellectual property disputes and expect to continue to do so in
the future.

    Beginning in the second quarter of this year, we plan to spend between $10
and $15 million to

    - market our technology to digital set-top box manufacturers, cable and
      other service providers and others in the home entertainment market and

    - increase customer awareness and product development efforts in the
      e-transactions market.

    As a result, we expect product development expense to increase more quickly
than revenue. We also expect marketing and sales expense to increase at a rate
that exceeds its historical rate of increase as a result of these expenditures.

    In June 1998 and June 1999, the AICPA issued Statement of Financial
Accounting Standards, or SFAS, No. 133 "Accounting for Derivative Instruments
and Hedging Activities" and SFAS No. 137, which delayed the effective date of
SFAS No. 133 and required its adoption beginning January 1, 2001. The Company
will adopt this standard in January 2001 and is currently analyzing the
statement to determine the impact, if any, on the Company's financial position
or results of operations.

</TABLE>

FISCAL YEAR ENDED DECEMBER 31, 1999 COMPARED WITH FISCAL YEAR ENDED
  DECEMBER 31, 1998

    Revenues increased 27% from $22.1 million in 1998 to $28.1 million in 1999.
This revenue growth is a result primarily of growth in sales to the business
communication market and, to a lesser extent, from a threefold increase in home
entertainment sales to $1.5 million reflecting our initial penetration of that
market.

    Gross profit as a percent of sales did not change appreciably.

    Product development and research expense increased from $1.4 million in 1998
to $2.2 million in 1999 while increasing marginally as a percentage of sales.
The increase reflects our continuing commitment to develop products that will
support our leadership position in our existing and targeted markets.

                                       22
<PAGE>
    Selling, general and administrative expense was $5.8 million in 1998 and
1999 but declined as a percentage of sales from 26% in 1998 to 20% in 1999. The
percentage decrease represents the amortization of a relatively stable general
and administrative burden over increased sales.

    Income taxes were significant for the first time in 1999 at $252,000, as our
Japanese subsidiary fully utilized its tax loss carryforwards and began to
accrue tax on income. We expect income taxes to increase absolutely and as a
percentage of pretax income as the federal and state income tax loss
carryforwards become fully utilized or expire as well. Other expense was
insignificant in 1999 and declined from 1998 as a result of a one-time charge
related to a legal settlement expense of $355,000 in 1998.

    Operating income was $2.4 million and net income was $2.1 million in 1999,
the increases over 1998 were primarily attributable to increased sales.

FISCAL YEAR ENDED DECEMBER 31, 1998 COMPARED WITH FISCAL YEAR ENDED
  DECEMBER 31, 1997

    Revenues increased 15% from $19.2 million in 1997 to $22.1 million in 1998.
This revenue growth resulted from our focus on developing and marketing our
computer pointing device product line primarily in the business communication
market.

    Gross profit as a percent of sales decreased from 38% in 1997 to 37% in
1998. This decline was a result of the growth of our sales to OEM customers,
which typically carry a lower gross profit percentage as compared to non-OEM
sales. Additionally, in 1998, the business communication industry experienced
the rapid product development and price competition typically experienced in the
computer hardware industry.

    Product development and research expense decreased from $1.6 million in 1997
to $1.4 million in 1998. During 1997, development costs were materially affected
by the development costs, both internal and external, relating to the
introduction of our VERSAPAD-REGISTERED TRADEMARK- technology and the
development of REMOTELINK technology. In 1998 resources were added to support
the increased OEM business both in the U.S. and Japan and to develop the new
product FREEDOMWRITER (first shipped in December 1998) and a new touchpad
peripheral introduced in July 1999.

    Selling, general and administrative expense as a percent of sales decreased
from 29% in 1997 to 26% in 1998. This decline resulted from the amortization of
relatively fixed costs over a greater base of sales and the shift in product mix
towards OEM sales.

    We recorded a profit from operations of $169,000 in 1997 and $888,000 in
1998. 1997 results were affected by a one-time write-off due to yield problems
related to the new VERSAPAD technology that more than offset continued strong
revenue growth and cost containment efforts. The improvement in 1998 was a
result of continued growth from the OEM business which allowed for strong cost
containment that offset the lower gross profit percentage.

    Other expense, relatively minor in prior years, reached $486,000 in 1998 due
to a one-time legal settlement expense of $355,000.

    The revenue growth in our computer pointing device product line, and
operating cost control contributed to achieve net income of $30,000 in 1997 and
$402,000 in 1998. The results in 1997 were affected by a one-time write-off due
to yield problems related to the new VERSAPAD technology that more than offset
continued strong revenue growth and cost containment efforts. The results in
1998 were negatively impacted by a one-time charge related to a legal settlement
of $355,000.

    Revenues declined slightly in the third quarter of 1998 when one of our key
OEM customers rescheduled certain orders from the third to the fourth quarters
of that year.

LIQUIDITY AND CAPITAL RESOURCES

    Working capital at December 31, 1999 was $17.6 million versus $14.1 million
at the end of 1998. This increase resulted from positive results from
operations, from the proceeds from debt agreements obtained through Japanese
banks and equity issuances related to employee stock options.

                                       24
<PAGE>
    Operations changed from a net user of cash of $479,000 in 1998 to a net
provider of cash of $2.9 million in 1999. This improvement resulted from the
positive results from operations coupled with improved accounts receivable and
inventory management and increases in accounts payable and accrued expenses.

    We spent $846,000 in 1998 and $529,000 in 1999 to purchase additional
manufacturing equipment and computer equipment related to our internal computer
network. In 1999, we invested $104,000 in new patents.

    In 1998, we negotiated an increase in the maximum available under our
Japanese bank line of credit to $1.1 million, none of which was used as of
December 31, 1999. Our U.S. line of credit was unused at December 31, 1999 and
had $3 million of availability as of that date. We also believe there are a
number of sources available for the leasing of equipment. The exercise of
outstanding stock options is a potential source of equity capital that may be
available to us. We believe that our current cash balances, lines of credit and
net proceeds from this offering will allow us to fund our operations for at
least the next 12 months. However, an unforeseen downturn of results in
sufficient magnitude could effect our ability to meet that forecast.

FOREIGN CURRENCY EXCHANGE RISK

    The Japanese subsidiary generally makes its sales and collects its accounts
receivable in Japanese yen. To hedge these revenues against future movements in
exchange rates, we will from time to time purchase foreign exchange forward
contracts. Gains or losses on the forward contracts are then offset by gains or
losses on the underlying exposure and consequently a sudden or significant
change of foreign exchange rates would not have a material impact on net income
or cash flows to the extent future revenues are protected by forward currency
contracts. During 1999, the Company entered into foreign currency exchange
contracts in the normal course of business to manage its exposure against
foreign currency fluctuations on revenues denominated in foreign currencies. The
principle objective of such contracts was to minimize the risks and costs
associated with financial and global operating activities. The Company does not
utilize financial instruments for trading or other speculative purposes. There
were no off balance sheet derivatives during 1997 or 1998. The fair value of
foreign currency exchange contracts is estimated by obtaining quotes from
brokers. At December 31, 1999, the Company had foreign currency exchange
contracts outstanding with a notional value of $5.4 million. During fiscal 1999,
the Company recognized $440,000 of losses on foreign currency exchange contracts
which is reflected in revenues in the accompanying consolidated statements of
operations.

OVERVIEW

    We are a leader in the development of intuitive interface devices for a
variety of home and business applications. Our products enable a user to
wirelessly control and communicate with various products such as digital set-top
boxes, digital televisions and other electronic products, which we refer to as
appliances, by providing an intuitive device on which the user can remotely
input a variety of commands. Our products incorporate patented sensor and
wireless communication technologies and proprietary applications and ergonomic
designs. We have recently begun to use our collection of intuitive interface
technologies, which were originally designed for our business presentation
products, to create products for two new markets: home entertainment and
electronic transactions. By building partnerships with providers of
complementary software and hardware technologies, we expect to market these
products for use with appliances as digital interface technology is incorporated
into them.

    We have recently completed development of a prototype device that will
enable users to easily control the various applications emerging in the home
entertainment market, such as interactive television. For the workflow
automation and business-to-business electronic commerce markets, which we refer
to collectively as the e-transactions market, we have also recently introduced
our EPAD electronic signature capture device. The EPAD captures signatures
electronically and permits these signatures to be bound to an electronic
document, allowing a recipient to verify that an electronic document has not
been tampered with since the signature was recorded. We are the leading supplier
of intuitive interface devices and components for the business presentation
market, where we sell both to OEMs and directly to consumers through reseller
channels. Our OEM customers include computer, computer peripheral and
presentation appliance manufacturers, such as inFocus, Inc., Koninklijke Philips
Electronics N.V., NEC Corporation, Sharp Corporation, Sony Corporation and
Toshiba Corporation. We also design, manufacture and sell a broad variety of
specialty components incorporating our technologies, such as pointing devices
and industrial sensor products for the computer, automotive and medical device
markets.

MARKET BACKGROUND

    The widespread adoption of the Internet and the proliferation of business
and home computing, information and entertainment appliances have prompted an
increase in the amount of interactive content and the number of entertainment
and business applications available in the home and business environments. The
emergence of new technologies and the appliances that support them is enabling
business and home users to use high-speed communications to access media and
interactive services, such as entertainment program guides, e-commerce, chat,
games, e-mail and interactive television. These technologies are expanding the
infrastructure for viewing content and interacting with applications beyond the
television and the personal computer. Business and home users currently interact
with these applications and access content through an array of appliances,
including digital set-top boxes, game consoles, DVD players and business
presentation projectors.

    CONVERGENCE OF TELEVISION, COMPUTER TECHNOLOGY AND THE INTERNET.  The
Internet has grown rapidly over the past several years and is now used by
millions of people for entertainment, education and e-commerce. Jupiter
Communications projects that by 2002, more than 60 million U.S. households will
have access to the Internet. The increasing popularity of the Internet and the
established popularity of television have led a growing number of home computer
users to simultaneously access Internet content while they watch television.
This convergence of television and computer technologies has enabled a wide
range of new communication and entertainment applications. Digital cable
networks will be able to offer consumers electronic program guides, voice
telephony, e-mail, e-commerce and other services through the television. For
example, a television viewer may, after viewing a movie, wish to order a copy on
DVD, or the viewer of a news program or television commercial may wish to obtain

                                       26
<PAGE>
additional information by visiting a related Website. These new applications are
creating a need for interactive appliances in the home entertainment,
e-transactions and business communication markets.

    HOME ENTERTAINMENT MARKET.  We believe that the home entertainment market
offers a new large market opportunity for multi-functional, intuitive interface
devices. The advent of digital cable, satellite TV and similar broadband
delivery systems is increasing programming choices. It is widely anticipated
that computer and television technologies will continue to converge and that the
consumer will be able, through a single electronic appliance, to view television
programming, control other entertainment components, access the Internet,
participate in on-line commerce, send and receive e-mail and participate in
audio and video telephone calls.

    We believe the market for intuitive interface devices will develop as cable
subscribers have increased access to digital set-top boxes. Forrester
Research, Inc. estimates that 15.3% of U.S. households will have digital set-top
boxes by year-end 2000, growing to 26.5% in 2002 and 55.3% in 2005. We believe
that, as digital set-top boxes are deployed and broadband services such as
Internet access become available, consumers will seek new control devices that
are more sophisticated, flexible, and intuitive than traditional television
remotes or the combination of a remote and wireless keyboard.

    E-TRANSACTIONS MARKET.  The rapid growth of the workflow automation and
business-to-business e-commerce markets has created a need for electronic
document and approval authentication methods that can serve as an electronic
substitute for the signature on paper documents. For the recipient of an
electronic document to have confidence that the document was approved in the
form in which it appears on his or her computer screen, it is necessary to have
a reliable mechanism that captures a signature, binds the signature to the
document, and verifies the identity of the approving person and the integrity of
the document in the form in which it was approved.

    We believe there is a sizeable market for an e-transactions product in
workflow automation applications, particularly in large business organizations
where there is a need to rapidly circulate documents for approval by a series of
people. We expect that e-transactions products will be deployed in this market
as the dollar value of business-to-business e-commerce grows from $406 billion
in 2000 to $2.7 trillion in 2004, as forecast by Forrester.

    BUSINESS COMMUNICATIONS MARKET.  As computer technology has replaced
traditional presentation devices such as slide and overhead projectors, the need
to control the presentation process has undergone a similar evolution. According
to Pacific Media Associates, the business communication market is growing at an
average annual rate of 23% with unit volumes expected to increase from 540,000
units in 1998 to 1.5 million units in 2003. Our OEM customers have recently
introduced business communication hardware that will significantly reduce the
size and weight and increase the resolution and brightness of presentation
devices such as projectors and the processing power of computers that support
them. Increased portability will enable many users to travel with a complete
presentation system capable of fitting in a standard computer bag.

THE NEED FOR INTUITIVE INTERFACE DEVICES

    In recent years, the number and types of computing, information and
entertainment appliances both in the home and in business have increased
dramatically. For example, a typical household may contain separate control
devices for the television, cable set-top box, DVD player, stereo system, game
console and PC. The convergence of television, computer technology and the
Internet has created interactive applications on both the PC and the television.
As a result, traditional application interface devices, such as a standard
keyboard, are no longer intuitive or capable of interacting across multiple
appliances.

    We believe traditional remote control devices are not well suited for
evolving user requirements. In the home environment, entertainment appliances
are increasing in complexity, more applications and

                                       27
<PAGE>
content can be accessed on each appliance, and multiple appliances are often
used simultaneously. However, the remote control devices that consumers
typically use to control applications and appliances in the home environment are
not intuitive and are often difficult to use. They typically contain many
buttons, which requires users to memorize or lookup each function of each
button. Users often need several control devices, such as a remote and a
wireless keyboard, to access multiple applications, such as digital TV content,
Internet-based communication and commerce, and the telephone.

    Moreover, the typical remote control device operates on infrared, or IR,
technology, which does not work well over long distances or if there are
intervening objects, such as furniture. IR signals also interfere with each
other, which prevents the use of multiple IR signals in a single room,
significantly limiting interactivity between the remote and the multiple devices
it controls and making bi-directional communication impossible. Finally, IR
technology limits speed and bandwidth, limiting the complexity of data that can
be transmitted.

    In the e-transactions market, businesses seeking to automate workflow or
conduct e-commerce transactions need a hardware and software solution that can
be used to capture signatures, bind them to documents, and authenticate and
verify them. There are few cost-effective turnkey solutions commercially
available that can be deployed, requiring businesses to develop proprietary
software and hardware solutions.

    In the business communications market, users need a highly reliable wireless
device to control their presentation or videoconferencing system. Users must be
able to move untethered to interact with their audience while simultaneously
controlling their equipment. Advanced presenters require the ability to annotate
on a slide or to modify their presentation during the actual presentation.

THE INTERLINK SOLUTION

    We use our collection of proprietary intuitive interface technologies to
create devices that enable users to operate and control computers, televisions,
projectors and other complex electronic appliances. By enabling interactivity
between interface devices and the appliances they control, we allow users to
interact directly with menu-driven application programs resident in the
controlled appliance through an on-screen display. Our devices will allow users
to use high bandwidth applications such as telephony and provide an intuitive
interface for applications encompassing the functions typically associated with
computers, such as browsing the Internet and sending and receiving e-mail. For
instance, our new interface device for next generation digital set-top boxes
will integrate cursorless navigation, text entry, freehand writing and drawing
and voice transmission capabilities within a single lightweight, hand-held
platform. The device will enable total control of various home entertainment
options available yet retain a highly intuitive user interface and a sleek
ergonomic design.

    Our interface devices offer a number of benefits not available on
traditional remote controls:

    EASY-TO-USE TOUCHPAD TECHNOLOGY.  All of our products include our patented
VERSAPAD touchpad technology. The touchpad incorporates our patented FORCE
SENSING RESISTOR and other technologies to create a pointing device that
responds to pressure and can accept input from a finger or a pen. The VERSAPAD
also consumes minimal power, making it ideal for use in a battery powered
interface device. In conjunction with pad-to-screen mapping and gestures, our
touchpads provide an intuitive means of communicating with a wide array of
applications and appliances.

    INTUITIVE PAD-TO-SCREEN MAPPING.  Our pad-to-screen, or PTS, mapping
technology, for which we have a patent pending, allows a user to touch a point
on a touchpad based on VERSAPAD technology to activate a button or menu item in
a corresponding on-screen location. This capability eliminates the need to click
or cursor through various intervening menu items. Using PTS mapping, a user can
easily and quickly perform a number of complex functions without looking at the
remote device, including the operation of a virtual keyboard activated through
the touchpad but appearing on the monitor.

                                       28
<PAGE>
    INNOVATIVE GESTURE CONTROL.  Our "gesture" technology, for which we have a
patent pending, allows the user to input or write commands on a screen by
touching and moving a finger or pen on a touchpad. For example, a channel can be
changed by tracing the channel number on the touchpad or, if a higher or lower
channel is desired, by swiping to the right or left, as applicable, and
continuing to touch the touchpad to scroll through the channel numbers. Other
commands, such as play, record or pause are accomplished by making gestures that
mimic the standard symbols for those functions appearing on VCRs, DVD players
and other playback and recording devices.

    ENHANCED WIRELESS COMMUNICATIONS TECHNOLOGY.  Our patented REMOTELINK
wireless communications technology retains the IR technology necessary to
communicate with most of today's appliances and combines it with radio
frequency, or RF, technology to overcome most of the shortcomings of traditional
IR technology. REMOTELINK permits our intuitive interface devices to:

    - send signals having sufficient speed and bandwidth to support applications
      such as handwriting input, stereo quality streaming audio and telephony;

    - support bi-directional and multiple signals, thereby enabling true
      interactive communication and/or the simultaneous use of multiple remote
      devices in a single room; and

    - send sufficiently robust signals to eliminate the need to point the remote
      device at the receiver for the controlled device.

    FUNCTIONAL AND ERGONOMIC DESIGN.  Our intuitive interface devices reflect
our strong focus on functionality and ergonomics. We maintain an active product
design effort and devote considerable attention to issues related to ease of use
of our products. An example of the results of these efforts is our patented
CLICKTRIGGER button incorporated in a number of our products, which enables the
user to click on an icon on a monitor by squeezing a button with his or her
index finger in a motion similar to pulling a trigger on a gun.

THE INTERLINK STRATEGY

    We intend to use our collection of technologies to become the leading
provider of intuitive interface devices for the home and business markets
through the implementation of the following strategies:

    DEVELOP INTUITIVE INTERFACE DEVICES THAT ARE COMPATIBLE WITH MOST HOME
ENTERTAINMENT APPLIANCES. We will introduce intuitive interface devices for the
home entertainment market that will enable users to take full advantage of the
many interactive applications that are starting to become widely available. We
are building technology partnerships with a variety of other technology
providers, such as multiple service operators, manufacturers of digital set-top
boxes and developers of software applications, to promote the compatibility of
our devices with as many different interactive home entertainment appliances and
systems as possible. In order to support this compatibility, we will develop or
partner with others to develop communication protocols that enable our interface
devices to function with the various applications available to consumers in the
home entertainment market and the appliances on which these applications will
run. Because many of our OEM customers in the business communications market are
also participants in the market for home entertainment appliances, we expect to
use our relationships with them to facilitate the widespread adoption of our
intuitive interface devices in this market.

    AGGRESSIVELY MARKET OUR EPAD PRODUCT TO THE E-TRANSACTIONS MARKET.  We will
foster adoption of our recently introduced EPAD product in the e-transactions
market by expanding distribution channels and building strategic relationships
with key software and systems integrators to develop turnkey solutions for
deployment in large-scale corporate settings. To foster adoption of the EPAD in
the workflow automation market, we are working with electronic signature
software companies like Silanis

                                       29
<PAGE>
Technology, Inc. and Communication Intelligence Corporation, or CIC. For
example, our EPAD APPROVEIT product is bundled with software from Silanis
Technology, Inc. We also are working with companies like Adobe Systems
Incorporated and Cardiff Software, Inc that are interested in promoting the
widespread use of electronic, rather than paper, documents in
business-to-business commerce.

    MAINTAIN OUR LEADERSHIP POSITION IN THE BUSINESS COMMUNICATIONS MARKET.  We
will seek to maintain our leadership position in the business communication
market by continuing to provide our OEM and reseller customers with innovative
products that are responsive to consumer needs. We also expect to introduce
products for related ancillary markets, such as conference room and video
conferencing controllers and conferencing automation products.

    DEVELOP PROPRIETARY APPLICATIONS TO FACILITATE OUR ENTRY INTO NEW
MARKETS.  We will develop either for ourselves or in partnership with other
companies, software applications that enhance the functionality of our intuitive
interface devices and will seek to license such applications where possible. We
are entering into strategic relationships with companies such as PSW
Technologies Inc. that can assist us in developing such software applications.
We intend to work with our customers and development partners to identify and
develop applications that will meet actual customer needs and, where
appropriate, to license these applications to appliance manufacturers, system
operators and others.

    ENHANCE OUR CURRENT TECHNOLOGY AND DEVELOP OR ACQUIRE NEW TECHNOLOGY AND
APPLICATIONS. We will maintain an active technology development program that
will enable us to enhance our current touchpad and wireless communication
technologies and develop new technologies and applications for them. We believe
this continuing development will allow us to increase our market share in the
markets in which we compete and identify new markets where are technologies can
provide us with a competitive advantage. Where appropriate, we may acquire
technologies from others or acquire companies that own or are developing
technologies that we believe would allow us to enhance our product offerings.

PRODUCTS

    We have four principal product lines targeted at the business communication,
home entertainment, e-transactions and specialty components markets.

    BUSINESS COMMUNICATION PRODUCTS.  Our intuitive interface devices are used
by the business communication market to control presentation appliances such as
projectors. Our traditional interface devices incorporate a pointing button to
control the cursor and one or more function selection buttons. These products
range from a simple interface device with only a pointing device and a single
click button to devices with 30 function keys. Most of these products
incorporate our patented CLICKTRIGGER button. We have recently introduced
interface devices based on our REMOTELINK technology incorporating a touchpad
and permitting the user, in addition to the normal presentation control
functions, to write over or highlight material appearing in the formal
presentation.

    We sell interface devices principally to OEMs and, to a lesser extent, as
branded products through a variety of distributors, value added resellers and
large retail chains. Our current customers include some of the largest
presentation device OEMs, including Seiko Epson Corporation, Hitachi, Ltd.,
inFocus, Inc., Mitsubishi Electronics America, Inc., NEC Corporation, Sanyo
Electric Co., Ltd., Sony Corporation and Toshiba Corporation. Although most
business presentation devices are made by Japanese companies, the United States
represents the largest market for these products. Accordingly, our OEM sales are
concentrated in Japan and managed by our Japanese subsidiary while our branded
sales are primarily U.S.-based.

    HOME ENTERTAINMENT PRODUCTS.  The INTUITOUCH product, our prototype
intuitive interface device for home entertainment appliances such as digital
set-top boxes, is based on a technological platform

                                       30
<PAGE>
similar to our most advanced business communications devices. The pad-centric
remote device we are developing will integrate mouse pointing, text entry,
freehand writing and drawing and voice transmission capabilities. The device
will enable total control of the variety of home entertainment options available
yet retain a highly intuitive user interface and an ergonomic design.

    E-TRANSACTIONS PRODUCTS.  Our EPAD product consists of a FSR-based, VERSAPAD
touchpad mounted in a plastic case and connected by a cable to a computer. Like
all of our FSR-based touchpads, it is actuated using a finger, electronic pen or
any other device capable of exerting pressure at a given point on the sensor.
The EPAD captures and binds signatures to electronic documents. We work with
major electronic signature software application developers to provide turnkey
solutions to end-users. Depending on the software used with it, the EPAD device
can perform a variety of document authentication functions, such as alerting a
reader if any change has been made to a document since it was transmitted by the
sender. Other potential functions include signature verification.

    SPECIALTY COMPONENTS.  Our specialty components business consists primarily
of two segments. We sell integrated pointing solutions to manufacturers of
notebook computers and industrial computers. We also sell a diverse assortment
of custom-designed sensors for non-computer applications, such as for use in
medical devices as safety switches and automotive components, such as car seats.

TECHNOLOGIES

    Our core technologies are FORCE SENSING RESISTORS and REMOTELINK, our
wireless communication protocol.

    FORCE SENSING RESISTORS.  All of our products incorporate one or more FSRs.
A basic FSR sensor can detect and accurately measure a force applied to it,
thereby enabling precise control of the process applying the force. A more
complex sensor, known as a "four zone" sensor, has four sensors arranged in a
two-by-two square with an actuator placed directly where the four sensors touch.
By toggling the actuator in any direction, an operator can control the direction
and speed of a cursor on a computer screen. An FSR sensor can also serve as a
touchpad by incorporating a two-dimensional grid capable of measuring the
location and intensity of pressure applied at any set of coordinates on the
grid. In contrast to most standard touchpads, FSR touchpads can also measure the
amount of pressure applied at any point on the grid, thereby creating a
three-dimensional matrix that can characterize an input along X, Y and Z axes.
This type of device is useful for functions such as handwriting input, where not
only the outline of the signature but the pressure applied in writing it can be
measured, or computer cursor control, where variable cursor speed is desirable.

    Our FSR sensors can be as thin as one-hundredth of an inch, making them
particularly well suited for use where space is a critical issue, as in notebook
and sub-notebook keyboards. In touchpad applications, they consume significantly
less power than do capacitive touchpads, the principal competing technology.
FSRs are therefore an appropriate choice for wireless applications. Also, unlike
capacitive touchpads which react to the electrical capacitance in a human
finger, FSRs react to pressure from any object and therefore support pen input.
FSR sensors have no moving parts and can be packaged in a sealed environment.
They are therefore highly reliable, retaining their performance through tens of
millions of actuations, even in adverse environments involving heat, moisture,
and chemical contamination.

    FSR sensors are manufactured using screen printing techniques. All
proprietary aspects of the manufacturing process are conducted in-house at
Interlink, to maintain quality and protect the force sensing technology. While
electronic screen printing is a common process in various technology industries,
the quality and precision of printing required to make high-quality FSR sensors
greatly exceeds the standards applicable in most other industries. We have
developed significant expertise in the manufacture of FSR sensors, and believe
this experience would be difficult to replicate over the

                                       31
<PAGE>
short term. In the FSR manufacturing process, printed sheets of FSR
semiconductor material and the corresponding conductor patterns are laminated to
form the FSR sandwich structure using inexpensive sheet adhesives. The assembled
sheets are die cut and suitable connectors are attached.

    REMOTELINK.  Our REMOTELINK technology uses a proprietary optical carrier
design to provide a relatively high speed, multi-channel, digital or analog,
optical communications link that does not interfere with, or become contaminated
by, signals from IR remote controls. REMOTELINK can be configured to support
multiple users and simultaneous channels operating over a number of carrier
frequency spectrums, including the 1 to 6 megahertz range. REMOTELINK'S
bandwidth supports wireless data transmissions of up to 100 kilobits per second
and a 6 kilohertz bandwidth analog transmission at distances of up to 10 meters.
REMOTELINK technology can simultaneously transmit data, voice and legacy IR
codes. REMOTELINK technology's ability to transmit legacy IR codes makes it
compatible with existing remote controls.

    APPLICATIONS.  We have created a number of applications that allow our
hardware technologies to support specific functions. These applications, for
example, enable our FSR-based touchpads to support PTS mapping and gesture
control. We expect to develop, or work with others to develop, new applications
that will allow our intuitive interface devices to control an ever increasing
number of interactive functions.

SALES AND MARKETING

    We employ a direct sales team of eight people in the U.S. and five in Japan.
Each sales team is supported by inside sales personnel, product managers and
application engineers. For our branded products, we also use value-added
resellers, system integrators and distributors throughout the U.S. and Europe.

    For OEM sales, we use public relations activity, direct advertising and
tradeshow participation to generate product awareness. Promising sales leads and
known industry targets are followed up with sales visits. Depending on forecast
volume and required lead times, we may sell component solutions,
ready-to-integrate modules, complete solutions or totally custom products. As
necessary, application engineers support and visit customers to promote ease of
integration. A successful OEM sale will generally take from 6 to 18 months from
the initial visit to the first shipment. However, once obtained, an OEM customer
usually offers us a more predictable revenue stream.

    For branded products, we use public relations, third-party product reviews,
trade shows and limited direct advertising to generate customer awareness.
Direct sales calls are made to potential distributors and specialty resellers.
Once a customer relationship is established, we support these customers with
co-op advertising, sales "spiffs," end-user rebates and other promotions.

    Current distribution channels for our branded products consist of mass
merchandiser outlets, such as Fry's Corporation, and distributors such as Ingram
Micro, catalogs and specialty resellers targeting corporate accounts. We market
to these channels with direct sales through our employees. In Europe we use
distributors and specialty resellers. We use these distribution channels not
only to increase branded product sales but also to establish customer demand for
new products that generate OEM sales.

    We are using our relationships with our OEM customers to facilitate the
introduction of our products in the home entertainment market. We also are
forming relationships with software developers, digital set-top box
manufacturers and cable and satellite television providers to enhance that
market's acceptance of our products and technologies. We anticipate using
similar sales and marketing techniques as those described above once we become
established in this market.

    We are conducting a variety of pilot projects with several potential
corporate purchasers of our EPAD product. Because we expect that the EPAD sales
channels will be different from those for our other

                                       32
<PAGE>
principal products, we are evaluating various sales and marketing options,
including partnership or licensing arrangements with third parties.

CUSTOMERS

    Our ten largest customers by revenue in 1999 were:

<TABLE>
<S>                                    <C>
NEC Corporation                        Hitachi, Ltd.
inFocus, Inc.                          Mitsubishi Electronics America, Inc.
Sony Corporation                       Toshiba Corporation
Sharp Corporation                      Varian, Inc.
Logitech International, S.A.           Microsoft Corporation
</TABLE>

    In 1999, we derived approximately $3.9 million, or 14.0%, of our revenue
from NEC, $3.5 million, or 12.4%, of our revenue from inFocus, and
$3.0 million, or 10.8%, of our revenue from Sony.

MANUFACTURING

    We manufacture FSR sensors in our facility in Camarillo, California. This
facility is capable of operating on a single, double, or triple shift basis, as
volume dictates. We acquire raw materials and components from a number of
sources, mostly within the United States. We have worked closely with a small
group of manufacturers to create new materials optimized for FSR usage; most of
these materials are supplied to us on an exclusive basis. The raw materials are
processed into their final form using proprietary material and methods. We
contract with two manufacturers in China to conduct most of our high volume,
non-FSR manufacturing operations.

COMPETITION

    We face competition from larger, more established companies that can produce
lower cost products using more mature technologies. Many of these companies have
greater financial, engineering and manufacturing resources than we do and have
long-standing customer relationships with key potential customers. While we
believe our technologies are superior, these competitors may develop or acquire
enhanced technologies sufficient to maintain or improve their market share.
Moreover, competitive pricing pressures on our OEM customers' products may force
them to choose lower cost, less sophisticated solutions from our competitors.

    In the business communications market, our competitors include Hoshiden and
SMK Corporation. In the home entertainment and e-transactions markets, we will
face competition from Koninklijke Philips Electronics N.V., Universal
Electronics Inc., Wacom Technology Co. and other smaller companies.

    We believe we can continue to compete effectively by continuing to develop
patented technologies that increase the functionality of the products of our OEM
customers. To maintain our patented technology advantage, we will continue to
invest heavily in product and advanced technology development. By manufacturing
most of our non-FSR components in countries with lower labor costs, we can
continue to offer high volume, low cost solutions.

RESEARCH AND DEVELOPMENT

    The business communications, home entertainment and e-transactions markets
are characterized by rapid and continuous technological development of the
appliances with which our products interface. For example, in the business
communications market, the computerized projector has rapidly become a powerful,
lightweight machine that is easily portable by its user. To maintain our
competitive position, we believe we must develop, in a timely manner, new
interface technologies and products and enhance

                                       33
<PAGE>
our existing technologies and products. Accordingly, we allocate a significant
amount of our financial resources to engineering, product and advanced
technology development. We also maintain close relationships with our customers,
which helps us anticipate their product needs.

    We employ 26 people in our product design, engineering support and advanced
technology departments in the US and in Japan. As appropriate, we engage outside
software development firms to facilitate the integration of our products into
our customers' appliances.

    Most of our current research and development efforts are focused on further
development of our intellectual property surrounding PTS mapping, gesture
control and the REMOTELINK communication protocol. Ongoing efforts are directed
at enhancing the ergonomics of our interface designs, such as touchpad input and
our CLICKTRIGGER control. Future efforts will be directed toward providing a
single chip solution for the REMOTELINK technology and software integration of
our home entertainment solution to next-generation digital set-top boxes. We do
not anticipate the development of technology unrelated to our customers'
evolving needs.

PATENTS AND INTELLECTUAL PROPERTY

    We regularly file patent applications and continuations to cover both new
and improved methods of manufacturing FSR sensors and non-FSR based
technologies.

    Aspects of our technology are protected by more than 65 patents issued or
pending in the United States and abroad, as well as by trade secrets and
proprietary knowledge. Products incorporating our force sensing technologies are
sold under trademarks issued or pending in the United States and various other
countries. Of the initial FSR patents granted, those which cover certain aspects
of the use of an uneven surface to produce variable resistance, the first of
these patents expired on September 24, 1999. We have continued our efforts to
improve the design, formulation, and manufacture of our sensors; some of these
improvements are maintained as trade secrets, while U.S. and foreign patents
have been applied for with respect to others. Other patents, covering various
apparatus, processes and methods related to the force sensing technology will
expire between 2000 and 2015. Various corresponding foreign patents will expire
between 2000 and 2015. U.S. patents covering various materials and processes
used in our current generation of products, as well as new devices for angle and
displacement sensing, were granted during 1995 and our CLICKTRIGGER design was
afforded patent protection in 1997. We have also filed U.S. and foreign patent
applications regarding the design, and several key operating features, of our
REMOTELINK technology.

    We have also developed certain manufacturing processes and other methods of
applying our patented technology that we protect as trade secrets. We believe
these trade secrets are important for the effective and efficient use of the
patented technology and that a competitor with a right to use the patented
technology would be required to develop comparable manufacturing and other
processes to compete effectively. We require our employees to sign nondisclosure
agreements and seek to limit access to sensitive information to the greatest
practical extent.

    We actively enforce our patents. When a potential infringing company is
identified, we first seek to notify the company of our patent rights.
Historically, we have been successful in negotiating license arrangements. If an
agreement cannot be reached, we will pursue legal remedies.

    While we believe our patents afford some competitive advantage, such
protection is limited by the resources available to us to identify potential
infringements and to defend our rights against infringement. The extent of the
protection offered by any patent is subject to determinations as to its scope
and validity that would be made only in litigation. We cannot be sure that our
patents will afford meaningful protection from competition.

                                       34

EMPLOYEES

    We had 130 full-time employees in the United States as of February 29, 2000;
101 at our corporate offices and manufacturing facilities, and two at our two
regional sales offices. Our Japanese subsidiary had 27 employees on that date.

FACILITIES

    Our corporate offices and principal manufacturing facilities are located in
a 35,333 square foot leased facility in Camarillo, California. The lease on the
Camarillo premises runs until August 2003 and provides for an average monthly
rent payment of $20,681. We believe that this facility will be adequate to meet
our requirements for at least the next 12 months. Our two regional sales offices
also operate out of leased facilities. Our Japanese subsidiary, Interlink
Electronics, K.K., leases office space in Tokyo.

LITIGATION

    We are not engaged in any litigation that we expect will have a material
adverse effect on our business, financial condition or results of operation.

    Upon completion of this offering, we will pay Sutro & Co. $500,000 to settle
a contractual dispute among the parties. As part of the settlement, the parties
terminated the subject agreement, and released each other from all obligations
under that agreement.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

    We are authorized to issue 15,000,000 shares of common stock, $.00001 par
value, and 100,000 shares of preferred stock, $5.00 par value. The following
summary describes all material provisions of our capital stock. However, we
encourage you to read the provisions of our certificate of incorporation and
bylaws, which, together with applicable Delaware law, contain the legal terms
that govern our capital stock.

COMMON STOCK

    As of March 20, 2000, there were 8,673,866 shares of our common stock
outstanding held of record by 55 stockholders, as adjusted to reflect a
three-for-two stock split effected in the form of a dividend to stockholders of
record on March 20, 2000.

    Holders of our common stock are entitled to one vote for each share held of
record on all matters submitted to a vote of stockholders. The vote of the
holders of a majority of the stock represented at a meeting at which a quorum is
present is generally required to take stockholder action, unless a greater vote
is required by law. The holders are not entitled to cumulative voting in the
election of directors. Accordingly, the holder or holders of a majority of the
outstanding shares of common stock will be able to elect all of the directors
who are up for election in any given year.

    Subject to preferences that may be applicable to any outstanding preferred
stock, the holders of common stock are entitled to receive ratably the
dividends, if any, as may be declared from time to time by the board of
directors out of funds legally available for that purpose. If we liquidate,
dissolve or wind up, the holders of common stock are entitled to share ratably
in all assets remaining after payment of liabilities, subject to the prior
distribution rights of preferred stock, if any, then outstanding. The holders of
common stock have no preemptive rights, conversion rights or other subscription
rights. There are no redemption or sinking fund provisions applicable to our
common stock. The outstanding shares of common stock are fully paid and
nonassessable. The rights of the holders of common stock will be subject to, and
may be adversely affected by, the rights of the holders of preferred stock.

PREFERRED STOCK

    Our 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 our common stock. Our board of directors, with
respect to each series of preferred stock, has the authority to determine:

    - the number of shares in and the distinguishing designation of that series;

    - whether shares of that series shall have full, special, conditional,
      limited or no voting rights, except to the extent otherwise provided by
      the law;

    - whether shares of that series shall be convertible and the terms and
      conditions of the conversion, including provision for adjustment of the
      conversion rate in circumstances determined by our board;

    - whether shares of that series shall be redeemable and the terms and
      conditions of redemption;

    - the dividend rate, if any, on shares of that series, the manner of
      calculating any dividends and the preferences of any dividends;

    - the rights of shares of that series in the event of voluntary or
      involuntary dissolution of Interlink and the rights of priority of that
      series relative to the common stock and any other series of preferred
      stock on the distribution of assets on dissolution; and

    - any other rights, preferences and limitations of that series that are
      permitted by law.

                                       40
<PAGE>
    It is not possible to state the actual effect of the issuance of any shares
of preferred stock upon the rights of holders of our common stock until the
board of directors determines the specific rights of the holders of preferred
stock. However, the effects might include restricting dividends on our common
stock; diluting the voting power of our common stock; impairing the liquidation
rights of our common stock; and delaying or preventing a change in control of
Interlink without further action by the stockholders.

    No shares of preferred stock are outstanding, and we have no present plans
to issue any shares of preferred stock.

TRANSFER AGENT AND REGISTRAR

    The transfer agent and registrar for our stock is American Securities
Transfer & Trust, Inc., located in Lakewood, Colorado and can be reached at
(303) 986-5400.

RESTRICTIONS ON CHANGE OF CONTROL

    Our certificate of incorporation and bylaws contain provisions that classify
the board of directors into three classes as nearly equal in number as possible,
each of which will serve for three years with one class being elected each year.
The classified board provisions may have the effect of lengthening the time
required for a third party to acquire control of Interlink through a proxy
contest or the election of a majority of the board of directors and may deter
any potential unfriendly offers or other efforts to obtain control of Interlink.
At the same time, these provisions may have the effect of inducing any third
parties seeking control of Interlink to negotiate terms acceptable to the board
of directors. In addition, since these provisions could make the removal of the
incumbent directors more difficult, that increases the likelihood that incumbent
directors will retain their position and, since the board has the power to
retain and discharge management, could perpetuate incumbent management.

    As a Delaware corporation, we are subject to Section 203 of the Delaware
General Corporation Law. In general, Section 203 prevents an "interested
stockholder" from engaging in a "business combination" with us for three years
following the date that person became an interested stockholder, unless:

    - before that person became an interested stockholder, our board of
      directors approved the transaction in which the interested stockholder
      became an interested stockholder or approved the business combination;

    - upon completion of the transaction that resulted in the interested
      stockholder becoming an interested stockholder, the interested stockholder
      owned at least 85% of our voting stock outstanding at the time the
      transaction commenced, excluding stock held by persons who are both
      directors and officers of Interlink or by certain employee stock plans; or

    - on or following the date on which that person became an interested
      stockholder, the business combination is approved by our board of
      directors and authorized at a meeting of stockholders by the affirmative
      vote of the holders of at least 66 2/3% of our outstanding voting stock
      excluding shares held by the interested stockholder.

    An "interested stockholder" is defined generally as a person owning 15% or
more of our outstanding voting stock. A "business combination" includes mergers,
asset sales and other transactions resulting in a financial benefit to the
interested stockholder.

                                  UNDERWRITING

    We and the selling stockholders are offering the shares of common stock
described in this prospectus through a number of underwriters. Banc of America
Securities LLC, FleetBoston Robertson Stephens Inc. and SoundView Technology
Group, Inc. are the representatives of the underwriters. We and the selling
stockholders entered into an underwriting agreement with the representatives.
Subject to the terms and conditions of the underwriting agreement, we and the
selling stockholders agreed to sell to the underwriters, and each underwriter
separately agreed to purchase, the number of shares of common stock listed next
to its name below at the public offering price, less the underwriting discounts
and commissions described on the cover page of this prospectus:

</TABLE>

    The underwriting agreement provides that the underwriters must buy all of
these shares if they buy any of them. The underwriters will sell these shares to
the public when and if the underwriters buy them from us and the selling
stockholders. The underwriters are offering the common stock subject to a number
of conditions, including:

    - the underwriters' receipt and acceptance of the common stock from us and
      the selling stockholders; and

    - the underwriters' right to reject orders in whole or in part.

    We and the selling stockholders have granted the underwriters an option to
buy up to 210,447 and up to 164,553, respectively, additional shares of our
common stock at the same price per share as they are paying for the shares shown
in the table above. The underwriters may exercise this option only to the extent
that they sell more than the total number of shares shown in the table above.
The underwriters may exercise this option at any time within 30 days after the
date of this prospectus. To the extent that the underwriters exercise this
option, the underwriters will be obligated to purchase the additional shares
from us and the selling stockholders in the same proportions as they purchased
the shares shown in the table above. If purchased, these additional shares will
be sold by the underwriters on the same terms as those on which the other shares
are sold.

    Our common stock is quoted on the Nasdaq National Market under the symbol
"LINK."

    The following table shows the per share and total underwriting discounts and
commissions to be paid by us and the selling stockholders to the underwriters.
These amounts are shown assuming no exercise and full exercise of the
underwriters' over-allotment option described above:

    The expenses of this offering, not including the underwriting discounts and
commissions, are estimated to be approximately $1.2 million and will be paid by
us. Expenses of this offering, exclusive of the underwriting discounts and
commissions, include the SEC filing fee, the NASD filing fee, Nasdaq listing
fees, printing expenses, legal and accounting fees, transfer agent and registrar
fees and other miscellaneous fees and expenses.

    We, our executive officers and directors have agreed not to sell or transfer
any shares of our common stock for 90 days after the date of this prospectus
without first obtaining the prior written

                                       42
<PAGE>
consent of Banc of America Securities LLC. Specifically, we and these other
individuals have agreed not to, directly or indirectly:

    - sell or offer to sell any shares of our common stock;

    - grant any option to sell any shares of our common stock;

    - engage in any short sale of our common stock;

    - pledge or otherwise transfer or dispose of any shares of our common stock;
      or

    - publicly announce an intention to do any of the foregoing.

    These lock-up agreements apply to shares of our common stock and also to any
options or warrants to acquire shares of our common stock, or securities
exchangeable or exercisable for or convertible into shares of our common stock.
These lock-up agreements apply to all such securities that are currently owned
or later acquired either of record or beneficially by the persons executing the
agreements. However, Banc of America Securities LLC may, in its sole discretion
and without notice, release some or all of the securities subject to these
agreements at any time during the 90 day period. Currently, there are no
agreements by the representatives to release any of the securities from the
lock-up agreements during such 90 day period.

    We and the selling stockholders will indemnify the underwriters against some
civil liabilities, including liabilities under the Securities Act and
liabilities arising from breaches of our representations and warranties
contained in the underwriting agreement. If we or the selling stockholders are
unable to provide this indemnification, we and the selling stockholders will
contribute to payments the underwriters may be required to make in respect of
those liabilities.

    The underwriters initially will offer the shares to the public at the price
specified on the cover page of this prospectus. The underwriters may allow to
selected dealers a concession of not more than $       per share. The
underwriters may also allow, and any other dealers may reallow, a concession of
not more than $               per share to some other dealers. If all the shares
are not sold at the public offering price, the underwriters may change the
public offering price and the other selling terms. A change in the public
offering price will not affect the amount of proceeds that we or the selling
stockholders receive.

    A prospectus in electronic format may be made available on the internet
sites or through other online services maintained by one or more of the
underwriters of this offering, or by their affiliates. In those cases,
prospective investors may view offering terms online and, depending upon the
particular underwriter, prospective investors may be allowed to place orders
online. The underwriters may agree with us to allocate a specific number of
shares for sale to online brokerage account holders. Any such allocation for
online distributions will be made by the representatives on the same basis as
other allocations.

    In particular, a prospectus in electronic format is being made available on
an Internet Website maintained by Wit SoundView's affiliate, Wit Capital
Corporation. Other than the prospectus in electronic format, the information on
Wit Capital's Website and any information contained on any other Website
maintained by Wit Capital is not part of the prospectus or the registration
statement of which this prospectus forms a part, has not been approved and/or
endorsed by us or any underwriter in its capacity as underwriter and should not
be relied upon by investors.

    The rules of the SEC generally prohibit the underwriters from trading in our
common stock on the open market during this offering. However, the underwriters
are allowed to engage in some open market transactions and other activities
during this offering that may cause the market price of our common stock to be
above or below that which would otherwise prevail in the open market. These
activities may include stabilization, short sales and over-allotments, syndicate
covering transactions and penalty bids.

                                       43
<PAGE>
    - Stabilizing transactions consist of bids or purchases made by the lead
      representative for the purpose of preventing or slowing a decline in the
      market price of our common stock while this offering is in progress.

    - Short sales and over-allotments occur when the representatives, on behalf
      of the underwriting syndicate, sell more of our shares than they purchase
      from us in this offering. In order to cover the resulting short position,
      the representatives may exercise the over-allotment option described above
      and/or they may engage in syndicate covering transactions.

    - Syndicate covering transactions are bids for or purchases of our common
      stock on the open market by the representatives on behalf of the
      underwriters in order to reduce a short position incurred by the
      representatives on behalf of the underwriters.

    - A penalty bid is an arrangement permitting the representatives to reclaim
      the selling concession that would otherwise accrue to an underwriter if
      the common stock originally sold by that underwriter was later repurchased
      by the representatives and therefore was not effectively sold to the
      public by such underwriter.

If the underwriters commence these activities, they may discontinue them at any
time without notice. The underwriters may carry out these transactions on the
Nasdaq National Market, in the over-the-counter market or otherwise.

    Prior to the pricing of this offering, and until the commencement of any
stabilizing bid, underwriters and dealers who are qualified market makers on the
Nasdaq National Market may engage in passive market making transactions. Passive
market making is allowed during the period when the SEC's rules would otherwise
prohibit market activity by the underwriters and dealers who are participating
in this offering. Passive market makers must comply with applicable volume and
price limitations and must be identified as such. In general, a passive market
maker must display its bid at a price not in excess of the highest independent
bid for our common stock; but if all independent bids are lowered below the
passive market maker's bid, the passive market maker must also lower its bid
once it exceeds specified purchase limits. Net purchases by a passive market
maker on each day are limited to a specified percentage of the passive market
maker's average daily trading volume in our common stock during a specified
period and must be discontinued when such limit is reached. Underwriters and
dealers are not required to engage in passive market making and may end passive
market making activities at any time.

    Some of the underwriters have in the past and may in the future perform
financial advisory services for us.

                                 LEGAL MATTERS

upon for us by Stoel Rives LLP, Portland, Oregon. Certain legal matters in

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Interlink Electronics, Inc.:

    We have audited the accompanying consolidated balance sheets of Interlink
Electronics, Inc. (a Delaware corporation) and its subsidiary as of
December 31, 1998 and 1999, and the related consolidated statements of
operations, stockholders' equity and cash flows for the three years then ended.
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 auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audits 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 Interlink Electronics, Inc.
and its subsidiary as of December 31, 1998 and 1999, and the results of their
operations and their cash flows for the three years then ended in conformity
with accounting principles generally accepted in the United States.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    Interlink Electronics, Inc. (the "Company") is engaged in the development of
intuitive interface technologies and solutions for a variety of business and
home applications. Products include interactive remote controls, pen input pads,
wireless keyboards and integrated mouse pointing devices. Force Sensing
Resistors are a key component of the Company's products.

    CONSOLIDATION POLICY--The consolidated financial statements include the
accounts of the Company and its 80 percent owned Japanese subsidiary. All
material intercompany accounts and transactions have been eliminated.

    REVENUE RECOGNITION--Revenue, net of allowances for returns and warranty, is
recorded upon shipment of the products. Royalty revenue is recorded when earned.

    FOREIGN CURRENCY TRANSLATION/TRANSACTIONS--The accounts of the Company's
foreign subsidiary have been translated according to the provisions of Statement
of Financial Accounting Standards, or SFAS, No. 52, "Foreign Currency
Translation." Management has determined that the functional currency of its
foreign subsidiary is the Japanese Yen. Thus all foreign translation gains or
losses are reflected as other comprehensive income in the consolidated statement
of stockholders' equity. The foreign subsidiary's balance sheets are translated
into U.S. dollars using the year-end exchange rate except for stockholders'
equity accounts, which are translated at rates in effect when these balances
were originally recorded. Revenues and expenses are translated at average rates
during the year. Any gain or loss resulting from foreign currency transactions
are reflected in the consolidated statement of operations for the period in
which they occur.

    CASH AND CASH EQUIVALENTS--The Company considers all highly liquid
investments purchased with an original maturity of three months or less to be
cash equivalents. Cash and cash equivalents are stated at cost, which
approximates market. At December 31, 1998 and 1999, the Company had
$3.0 million and $5.8 million, respectively, of cash in excess of federally
insured limits.

    FINANCIAL INSTRUMENTS--The carrying amounts of line of credit, long-term
debt and capital lease obligations approximate their fair value as interest
rates approximate market rates for similar instruments. During 1999, the Company
entered into foreign currency exchange contracts in the normal course of
business to manage its exposure against foreign currency fluctuations on
revenues denominated in foreign currencies. The principle objective of such
contracts was to minimize the risks and costs associated with financial and
global operating activities. The Company does not utilize financial instruments
for trading or other speculative purposes. There were no off balance sheet
derivatives during 1997 or 1998. The fair value of foreign currency contracts is
estimated by obtaining quotes from brokers. At December 31, 1999, the Company
had foreign currency contracts outstanding with a notional and fair value of
$5.4 million. During fiscal 1999, the Company recognized $440,000 of losses on
foreign exchange contracts which is included in revenues in the accompanying
consolidated statements of operations.

    INVENTORIES--Inventories are stated at the lower of cost or market and
includes material, labor, and factory overhead. Cost is determined using the
average cost method.

    PROPERTY AND EQUIPMENT--Property and equipment are carried at cost less
accumulated depreciation and amortization. Depreciation is recorded on the
straight-line basis over the estimated useful lives of the assets which range
from three to ten years. Amortization of leasehold improvements is based upon
the estimated useful lives of the assets or the term of the lease, whichever is
shorter. Maintenance and repairs are charged to operations as incurred, while
significant improvements are capitalized. Upon

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
retirement or disposition of property, the asset and related accumulated
depreciation or amortization are removed from the accounts and any resulting
gain or loss is charged to operations.

    PATENTS AND TRADEMARKS--The costs of acquiring patents and trademarks are
amortized on a straight-line basis over their estimated useful lives, ranging
from seven to seventeen years. Amortization expense for the years ended
December 31, 1997, 1998 and 1999 was $90,000, $98,000 and $99,000, respectively.

    INCOME TAXES--The Company accounts for taxes under Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes". Under this
statement, deferred tax assets and liabilities represent the tax effects,
calculated at currently effective rates, of future deductible taxable amounts
attributable to events that have been recognized on a cumulative basis in the
financial statements (see Note 10).

    EARNINGS PER SHARE--Earnings per share-basic is based upon the weighted
average number of shares outstanding. Earnings per share-diluted is based on the
weighted average shares outstanding including the dilutive effect of common
stock equivalents. (See Note 8)

    ACCOUNTS RECEIVABLE--Increases to the allowance for doubtful accounts
totaled $42,000, $177,000 and $183,000 for the years ended December 31, 1997,
1998 and 1999, respectively. Write-offs against the allowance for doubtful
accounts totaled, $139,000. $67,000 and $25,000 for the years ended
December 31, 1997, 1998 and 1999, respectively.

    USE OF ESTIMATES--The preparation of consolidated financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reported period. Actual results could differ from those estimates.

    RECENT PRONOUNCEMENTS--In June 1998 and June 1999, the AICPA issued SFAS
No. 133 "Accounting for Derivative Instruments and Hedging Activities" and SFAS
No.137, which delayed the effective date of SFAS No. 133 and required its
adoption beginning January 1, 2001. The Company will adopt this standard in
January 2001 and is currently analyzing the statement to determine the impact,
if any, on the Company's financial position or results of operations.

    RECLASSIFICATIONS--Certain prior year balances have been reclassified to
conform to the current year presentation.

8. EARNINGS PER SHARE

    For all periods presented, per share information was computed pursuant to
provisions of SFAS No. 128 "Earnings Per Share." The computation of earnings per
share--basic is based upon the weighted average number of common shares
outstanding during the periods presented. Earnings per share--diluted also
includes the effect of common shares contingently issuable from options and
warrants (in periods which they have a dilutive effect).

    Common stock equivalents are calculated using the treasury stock method.
Under the treasury stock method, the proceeds from the assumed conversion of
options and warrants are used to repurchase outstanding shares, using a yearly
average market price.

    The following table contains information necessary to calculate earnings per
share (in thousands):

    A valuation allowance is recorded if the weight of available evidence
suggests it is more likely than not that some portion or all of the deferred tax
asset will not be recognized. There is no assurance that the Company will
continue to be profitable in future periods, therefore, a valuation allowance
has been recognized for the full amount of the deferred tax asset for 1998 and
1999.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Section 145 of the Delaware General Corporation Law (the "DGCL") authorizes
a court to award, or a corporation's board of directors to grant, indemnity to
directors and officers on terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended (the "Securities Act"). As permitted by the DGCL, Article IV of the
Registrant's Certificate of Incorporation (the "Certificate") includes a
provision that eliminates the personal liability of its directors for monetary
damages for conduct as a director, except for any act or omission for which such
elimination of liability is not permitted under the DGCL. The Bylaws deny the
directors and others the right to indemnification for liability (i) for any
breach of the director's duty of loyalty to the Registrant or its stockholders,
(ii) for acts or omissions not in good faith or that involve intentional
misconduct or a knowing violation of law, (iii) under section 174 of the DGCL
(regarding unlawful dividends and stock purchases) or (iv) for any transaction
from which the director derived an improper personal benefit. As permitted by
the DGCL, the Certificate and the Bylaws of the Registrant also provide that
(i) the Registrant may indemnify its other employees and agents as set forth in
the DGCL, (ii) the Registrant is required to advance expenses, as incurred, to
its directors and executive officers in connection with a legal proceeding to
the fullest extent permitted by the DGCL, subject to certain limited exceptions
and (iii) the rights conferred in the Bylaws are not exclusive. At present,
there is no pending litigation or proceeding involving a director, officer or
employee of the Registrant regarding which indemnification is sought, nor is the
Registrant aware of any threatened litigation that may result in claims for
indemnification. The indemnification provisions in the Registrant's Certificate
and Bylaws may be sufficiently broad to permit indemnification of the
Registrant's directors and executive officers for liabilities arising under the
Securities Act.

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

ITEM 17. UNDERTAKINGS

(a) The undersigned registrant hereby undertakes:

               (1) To file, during any period in which offers or sales are being
           made, a post-effective amendment to this registration statement:

           (A) To include any prospectus required by section 10(a)(3) of the
       Securities Act of 1933;

           (B) To reflect in the prospectus any facts or events arising after
       the effective date of the registration statement (or the most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth in
       the registration statement PROVIDED, HOWEVER, that any increase or
       decrease in volume of securities offered (if the total dollar value of
       securities offered would not exceed that which was registered) and any
       deviation from the low or high end of the estimated maximum offering
       range may be reflected in the form of prospectus filed with the
       Commission pursuant to Rule 424(b) if, in the aggregate, the changes in
       volume and price represent no more than a 20% change in the maximum
       aggregate offering price set forth in the "Calculation of Registration
       Fee" table in the effective registration statement; and

           (C) To include any material information with respect to the plan of
       distribution not previously disclosed in the registration statement or
       any material change to such information in the registration statement;

PROVIDED, HOWEVER, that paragraphs (a)(1)(A) and (a)(1)(B) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the registrant pursuant to section 13 or section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the
registration statement.

        (2) That, for the purpose of determining any liability under the
    Securities Act of 1933, each such post-effective amendment 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.

        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.

    (b) The undersigned registrant hereby undertakes that, for purposes of
determining liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or

                                      II-2
<PAGE>
section 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to
section 15(d) of the Securities Exchange Act of 1934) that is incorporated by
reference in the registration statement 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.

    (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the provisions described under "Underwriting" and
Item 15, 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 of 1933 and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act of 1933 and will be governed by the
final adjudication of such issue.
