INSIGNIA SOLUTIONS PLC

Insignia, which commenced operations in 1986, develops, markets and supports
virtual machine technology that enables software applications and operating
systems to be run on various computer platforms. In late 1997, we began a
strategic review of our business and explored new markets that would leverage
our 15 years of emulation software development experience. In January 1998, we
announced our intention to launch a new product line. This product line, called
Jeode-TM-, is based on Insignia's Embedded Virtual Machine, or EVM-TM-,
technology. Jeode is our implementation of Sun Microsystems, Inc.'s
Java-Registered Trademark- technology developed specifically for Internet
appliances and wireless devices. The Jeode platform is enabled by our EVM and is
designed to enable software developers to create reliable, efficient and
predictable Internet appliances and wireless devices.

Jeode became available in March 1999 and generated 23% of our total revenues
for 1999 and 98% of our total revenues for 2000. Jeode is our principal product
line for the foreseeable future. The Jeode product line revenue model is based
on original equipment manufacturer's customer transactions. We derive revenue
from the Jeode product line from four main sources: the sale of a development
license, the sale of annual maintenance and support, a commercial use royalty
based on shipments of products that include Jeode technology, and
customer-funded engineering activities.

Our principal executive offices in the United States are located at 41300
Christy Street, Fremont, California 94538. Our telephone number at that location
is (510) 360-3700. Our principal executive offices in the United Kingdom are
located at The Mercury Centre, Wycombe Lane, Wooburn Green, High Wycombe, Bucks
HP10 0HH. Our telephone number at that location is (44) 1628-539500.

RISK FACTORS

THIS OFFERING IS RISKY. ANYONE WHO PURCHASES SHARES UNDER THIS PROSPECTUS
SHOULD CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS IN ADDITION TO THE OTHER
INFORMATION PRESENTED IN OR INCORPORATED BY REFERENCE INTO THIS PROSPECTUS AND
ANY PROSPECTUS SUPPLEMENT.

WE MUST SELL PRODUCTS IN OUR JEODE PRODUCT LINE TO PRODUCE REVENUES.

Our future performance depends upon sales of products within our Jeode
product line, which is a relatively new product line. During the fourth quarter
of 2000, revenues of products in the Jeode product line were $3.3 million, which
was 100% of our total revenue for the quarter. We incurred an operating loss of
$1.1 million in the fourth quarter of 2000. Jeode may not achieve or sustain
market acceptance or provide the desired revenue levels. At current overhead
levels, we require revenues of more than $5.3 million per quarter to achieve an
operating profit. The Jeode product line is our sole product line and we rely
and will continue to rely upon sales of Jeode products for our revenue for the
foreseeable future.

THE LONG AND COMPLEX PROCESS OF LICENSING OUR JEODE PRODUCT MAKES OUR REVENUE
UNPREDICTABLE.

Our revenue is dependent upon our ability to license the Jeode product to
third parties. Licensing our Jeode product is a long and complex process. Before
committing to license our product, potential customers must generally consider a
wide range of issues including product benefits, infrastructure requirements,
ability to work with existing systems, functionality and reliability. The
process of entering into a development license with a company typically involves
lengthy negotiations. As a result of the sales cycle, it is difficult for us to
predict when, or if, a particular prospect might sign a license agreement.
Development license fees may be delayed or reduced as a result of this process.

OUR LICENSEES MUST INTEGRATE OUR JEODE TECHNOLOGY INTO THEIR PRODUCTS, WHICH
DELAYS OUR RECEIPT OF REVENUES FROM COMMERCIAL LICENSES.

Our success depends upon the use of our technology by our licensees in their
Internet appliances or wireless devices. Our licensees undertake a lengthy
process of developing systems that use our technology. When a licensee enters
into a development license with us, we normally require the licensee to prepay
some future commercial use royalties, typically an amount projected to cover 3
to 6 months of future usage. Thereafter, until a licensee has sales of its
systems incorporating our technology which generate sufficient commercial use
royalties to surpass any prepayment to us, we do not receive any further
royalties from that licensee. We expect that the period of time between entering
into a development license and actually recognizing commercial use royalties to
be not only lengthy, but contingent on many factors, which makes it difficult
for us to predict when we will recognize royalties from commercial use licenses.

IF WE LOSE THIRD-PARTY LICENSE RIGHTS, WE MAY NOT BE ABLE TO SELL OUR JEODE
PRODUCTS.

In the first quarter of 1999, we signed a five-year agreement with Sun
Microsystems, Inc. under which Sun established Insignia as a Sun authorized
virtual machine provider. The agreement also grants us immediate access to the
Java compatibility test suite and the Java technology source code. The agreement
includes technology sharing and compatibility verification. Under the agreement,
we will pay Sun a per unit royalty on each Jeode-enabled Internet appliance or
wireless device shipped by our customers, plus a royalty on all development
licenses between our customers and us. If the agreement with Sun terminates or
expires without renewal, we would not be able to market our Jeode product line.
Any disruption in our relationship with Sun would likely impair our sales of
Jeode.

We also license software development tool products from other companies to
distribute with some of our products. These third parties may not be able to
provide competitive products with adequate features and high quality on a timely
basis or to provide sales and marketing cooperation. In addition, our products
compete with products produced by some of our licensors. When these licenses
terminate or expire, continued license rights might not be available to us on
reasonable terms. In addition, we might not be able to obtain similar products
to substitute into our tool suites.

IF ADDITIONAL FUNDS ARE NOT AVAILABLE AS NEEDED, WE MAY NOT BE ABLE TO TAKE
ADVANTAGE OF MARKET OPPORTUNITIES OR OTHERWISE GROW OUR BUSINESS.

We may need to raise additional funds in the future, and additional
financing may not be available on favorable terms, if at all. Further, if we
issue additional equity securities, security holders may experience dilution,
and the new equity securities may have rights, preferences or privileges senior
to those of our ordinary shares. If we cannot raise funds on acceptable terms,
we may not have sufficient net assets to maintain the listing of our shares on
the Nasdaq National Market. Further, we may not be able to develop new products
or enhance our existing products, take advantage of future opportunities or
respond to competitive pressures or unanticipated requirements. We believe the
proceeds from a private placement that closed on November 24, 2000 and on
February 12, 2001 will be sufficient to fund our planned growth through March
2002.

WE HAVE A HISTORY OF LOSSES AND WE MUST GENERATE SIGNIFICANTLY GREATER REVENUE
IF WE ARE TO ACHIEVE PROFITABILITY.

We have experienced operating losses in each quarter since the second
quarter of 1996. To achieve profitability, we will have to increase our revenue
significantly. Our ability to increase revenues depends upon the success of our
Jeode product line. Jeode is a relatively new product and it may not achieve
market acceptance. If we are unable to generate revenues from Jeode in the form
of development

license fees, maintenance and support fees, commercial use royalties and
customer-funded engineering services, our current revenues will be insufficient
to sustain our business.

WE EXPECT OUR SALES AND MARKETING EXPENSES TO CONTINUE AT HIGH LEVELS.

We expect to continue to incur disproportionately high sales and marketing
expenses for the foreseeable future. To market Jeode effectively, we must
further develop direct sales channels in the Internet appliance and wireless
device market. We must continue to incur the expenses for a sales and marketing
infrastructure before we recognize significant revenue from sales of the
product. Because customers in the Internet appliance and wireless device market
tend to remain with the same vendor over time, we believe that we must devote
significant resources to each potential sale. To the extent potential customers
do not design our products into their systems, the resources we have devoted to
the sales prospect would be lost. If we fail to achieve and sustain significant
increases in our quarterly sales, we may not be able to continue to increase our
investment in these areas. In addition, with increased expenses, we must
significantly increase our revenues if we are to become profitable.

IF OUR NEW PRODUCTS OR PRODUCT ENHANCEMENTS FAIL TO ACHIEVE CUSTOMER ACCEPTANCE,
OR IF WE FAIL TO MANAGE PRODUCT TRANSITIONS, OUR BUSINESS REPUTATION AND
FINANCIAL PERFORMANCE WOULD SUFFER.

The market for Internet appliances and wireless devices is fragmented and is
characterized by technological change, evolving industry standards and rapid
changes in customer requirements. Our existing products will be rendered less
competitive or obsolete if we fail to introduce new products or product
enhancements that anticipate the features and functionality that customers
demand. The success of our new product introductions will depend on our ability
to:

- accurately anticipate industry trends and changes in technology standards;

- complete and introduce new product designs and features in a timely
manner;

- continue to enhance our existing product lines;

- offer our products across a spectrum of microprocessor families used in
the Internet appliance and wireless devices market; and

- respond promptly to customers' requirements and preferences.

In addition, the introduction of new or enhanced products also requires that
we manage the transition from older products to minimize disruption in customer
ordering patterns.

Development delays are commonplace in the software industry. We have
experienced delays in the development of new products and the enhancement of
existing products in the past and are likely to experience delays in the future.
We may not be successful in developing and marketing, on a timely basis or at
all, competitive products, product enhancements and new products that respond to
technological change, changes in customer requirements and emerging industry
standards.

COMPETITION CAN LEAD TO PRICING PRESSURES AND REDUCED MARKET SHARE.

The market for commercially available Internet appliances and wireless
devices is fragmented and highly competitive. The Jeode product line is targeted
to the emerging Java-based Internet appliance and wireless device marketplace,
which is rapidly changing and is characterized by an increasing number of new
entrants whose products compete with Jeode. As the industry continues to
develop, we expect competition to increase in the future from existing
competitors and from other companies that may enter our existing or future
markets with similar or substitute solutions that may be less costly or provide
better performance or functionality than our products. Many of our current
competitors, as well as potential competitors, have substantially greater
financial, technical, marketing and sales resources than we do, and we might not
be able to compete successfully against these companies. If

price competition increases significantly, competitive pressures could cause us
to reduce the prices of our products, which would result in reduced profit
margins and could harm our ability to provide adequate service to our customers.
Our pricing model for our software products is based on a range of mid-priced
development license packages, combined with low-priced per-unit production, or
commercial use, licenses. Commercial use licenses, which provide for per-unit
royalty payments for each Internet appliance or wireless device that
incorporates our technology, may be subject to significant pricing pressures,
including buy-out arrangements. Also, the market may demand alternative pricing
models in the future. A variety of other potential actions by our competitors,
including increased promotion and accelerated introduction of new or enhanced
products, could also harm our competitive position.

FLUCTUATIONS IN OUR QUARTERLY RESULTS COULD CAUSE THE MARKET PRICE OF OUR ADSS
TO DECLINE.

Our quarterly operating results can vary significantly depending on a number
of factors. These factors include:

- the volume and timing of orders received during the quarter;

- the mix of and changes in customers to whom our products are sold;

- the mix of product and service revenue received during the quarter;

- the mix of development license fees and commercial use royalties received;

- the timing and acceptance of new products and product enhancements by us
or by our competitors;

- changes in pricing;

- buyouts of commercial use licenses;

- product life cycles;

- the level of our sales of third party products;

- variances in costs associated with fixed price contracts;

- purchasing patterns of customers;

- competitive conditions in the industry;

- foreign currency exchange rate fluctuations;

- business cycles and economic conditions that affect the markets for our
products; and

- extraordinary events, such as litigation, including related charges.

All of these factors are difficult to forecast. Our future operating results
may fluctuate as a result of these and other factors, including our ability to
continue to develop innovative and competitive products. An increasing amount of
our sales orders involve products and services that yield revenue over multiple
quarters or upon completion of performance. If license agreements entered into
during a quarter do not meet our revenue recognition criteria, even if we meet
or exceed our forecast of aggregate licensing and other contracting activity, it
is possible that our revenues would not meet expectations.

Due to all of these factors, we believe that period-to-period comparisons of
our results of operations are not necessarily meaningful and should not be
viewed as an indication of our future performance. In the past, we have
experienced actual performance that did not meet financial market expectations.
It is likely that, in some future quarters, our operating results will again be
below the expectations of stock market analysts and investors.

INTERNATIONAL SALES OF OUR PRODUCTS, WHICH WE EXPECT TO ACCOUNT FOR A
SIGNIFICANT PORTION OF OUR TOTAL REVENUE IN THE FUTURE, EXPOSE US TO THE
BUSINESS AND ECONOMIC RISKS OF INTERNATIONAL OPERATIONS.

Sales from outside of the United States accounted for approximately 15% of
our total revenue in 1999 and 18% of our total revenue in 2000 and are expected
to increase over time. We market Jeode to manufacturers of Internet appliance
and wireless devices in Europe and Asia, particularly in Japan. Economic
conditions in Asia and Europe generally, as well as fluctuations in the value of
the Japanese yen and the Euro against the U.S. dollar and British pound
sterling, could impair our revenues and results of operations. International
operations are subject to a number of other special risks. These risks include:

- foreign government regulation;

- reduced protection of intellectual property rights in some countries where
we do business;

- longer receivable collection periods and greater difficulty in accounts
receivable collection;

- unexpected changes in, or imposition of, regulatory requirements, tariffs,
import and export restrictions and other barriers and restrictions;

- potentially adverse tax consequences;

- the burdens of complying with a variety of foreign laws and staffing and
managing foreign operations;

- general geopolitical risks, such as political and economic instability,
hostilities with neighboring countries and changes in diplomatic and trade
relationships; and

- possible recessionary environments in economies outside the United States.

PRODUCT DEFECTS CAN BE EXPENSIVE TO FIX AND CAN CAUSE US TO LOSE CUSTOMERS.

As a result of their complexity, software products may contain undetected
errors or compatibility issues, particularly when first introduced or as new
versions are released. Despite testing by us and testing and use by current and
potential customers, errors might be found in new products after commencement of
commercial shipments. The occurrence of errors could result in loss of or delay
in market acceptance of our products. The increasing use of our products for
applications in systems that interact directly with the general public,
particularly applications in transportation, medical systems and other markets
where the failure of the Internet appliances or wireless devices could cause
substantial property damage or personal injury, could expose us to significant
product liability claims. In addition, our products are used for applications in
business systems where the failure of our product could be linked to substantial
economic loss. Our license and other agreements with our customers typically
contain provisions designed to limit our exposure to potential product liability
and other claims. It is likely, however, that the limitation of liability
provisions contained in our agreements are not effective in all circumstances
and in all jurisdictions. We may not have adequate insurance against product
liability risks and renewal of our insurance may not be available to us on
commercially reasonable terms. Our errors and omissions insurance may not be
adequate to cover claims. A product liability claim or claim for economic loss
brought against us, or a product recall involving our software, could lead to
significant unexpected expenses and lost sales.

Our operations depend on our ability to protect our computer equipment and
the information stored in our databases against damage by fire, natural
disaster, power loss, telecommunications failure, unauthorized intrusion and
other catastrophic events. We believe we have taken prudent measures to reduce
the risk of interruption in our operations. However, these measures might not be
sufficient.

IF WE LOSE KEY PERSONNEL OR ARE UNABLE TO HIRE ADDITIONAL QUALIFIED PERSONNEL AS
NECESSARY, WE MAY NOT BE ABLE TO SUCCESSFULLY MANAGE OUR BUSINESS OR SELL OUR
PRODUCTS.

Our future performance depends to a significant degree upon the continued
contributions of our key management, product development, sales, marketing and
operations personnel. We do not have agreements with any of our key personnel
that require them to work for us for a specific term, and we do not maintain any
key person life insurance policies. In addition, we believe our future success
will also depend in large part upon our ability to attract and retain highly
skilled managerial, engineering, sales, marketing and operations personnel, many
of whom are in great demand. Competition for qualified personnel is intense in
the San Francisco Bay area, where our United States operations are
headquartered, and we may not be able to attract and retain personnel.

Mr. Stephen M. Ambler has left the employment of the Company. Mr. Ambler was
the Company's Chief Financial Officer, Company Secretary and Senior Vice
President. His last day with the Company was March 15, 2001. The Company has
named Mr. Albert Wood as Mr. Ambler's replacement and will be the Company's
Chief Financial Officer effective April 1, 2001. The Company does not believe
that Mr. Ambler's departure will have a material adverse effect on the Company's
business, financial condition or results of operations. In the interim,
Mr. Richard M. Noling, the Company's President and Chief Executive Officer, will
be serving as the Company's Chief Financial Officer and Secretary.

OUR INABILITY TO PROTECT OUR INTELLECTUAL PROPERTY RIGHTS FROM THIRD-PARTY
CHALLENGES MAY SIGNIFICANTLY IMPAIR OUR COMPETITIVE POSITION.

We depend on our proprietary technology. Despite our efforts to protect our
proprietary rights, it may be possible for unauthorized third parties to copy
our products or to reverse engineer or obtain and use information that we regard
as proprietary. Our competitors could independently develop technologies that
are substantially equivalent or superior to our technologies. Policing
unauthorized use of our products is difficult, and while we are unable to
determine the extent to which software piracy of our products exists, software
piracy can be expected to be a persistent problem. In addition, effective
protection of intellectual property rights may be unavailable or limited in
foreign countries. The status of United States patent protection in the software
industry is not well defined and will evolve as the United States Patent and
Trademark Office grants additional patents. Patents have been granted on
fundamental technologies in software, and patents may issue that relate to
fundamental technologies incorporated into our products.

OUR PRODUCTS MAY INFRINGE ON THE INTELLECTUAL PROPERTY RIGHTS OF THIRD PARTIES,
WHICH MAY RESULT IN LAWSUITS AND PREVENT US FROM SELLING OUR PRODUCTS.

As the number of patents, copyrights, trademarks and other intellectual
property rights in our industry increases, products based on our technology may
increasingly become the subject of infringement claims. Third parties could
assert infringement claims against us in the future. Infringement claims with or
without merit could be time consuming, result in costly litigation, cause
product shipment delays or require us to enter into royalty or licensing
agreements. Royalty or licensing agreements, if required, might not be available
on terms acceptable to us. In addition, we may initiate claims or litigation
against third parties for infringement of our proprietary rights or to establish
the validity of our proprietary rights. Litigation to determine the validity of
any claims, whether or not the litigation is resolved in our favor, could result
in significant expense to us and divert the efforts of our technical and
management personnel from productive tasks. In the event of an adverse ruling in
any litigation, we may be required to pay substantial damages, discontinue the
use and sale of infringing products, expend significant resources to develop
non-infringing technology or obtain licenses to infringing technology. Our
failure to develop or license a substitute technology could prevent us from
selling our products.

CERTAIN SECURITY HOLDERS HAVE RIGHTS UNDER THEIR WARRANTS TO PURCHASE
SIGNIFICANT NUMBERS OF ADSS AT NOMINAL VALUE UPON THE OCCURRENCE OF SPECIFIED
EVENTS WHICH, IF TRIGGERED, WOULD DILUTE THE OWNERSHIP INTERESTS OF EXISTING
SECURITY HOLDERS.

Certain security holders, including the selling security holders, who hold a
total of 4,540,000 ADSs and warrants to purchase an additional 2,270,000 ADSs
have rights under their subscription agreements to be issued additional ADSs by
Insignia if the registration statement covering their shares and the shares
underlying their warrants is suspended for more than 60 days in any 12 month
period by Insignia. Other security holders have rights under their warrants to
purchase additional ADSs if our 10-day average closing and price share price on
the Nasdaq National Market falls below specified levels for a specified time. In
these circumstances, the purchase price these security holders will pay per
additional ADS is the nominal value, or L0.20 per ADS, which is the lowest
amount these shares can be purchased under English law. If we issue additional
ADSs under these obligations, the ownership interest of existing security
holders will be diluted.

WE ARE AT RISK OF SECURITIES CLASS ACTION LITIGATION DUE TO OUR SHARE PRICE
VOLATILITY.

The prices for our ADSs have fluctuated widely in the past. During the 12
months ended March 21, 2001, the closing price of a share of our common stock
ranged from a high of $27.50 to the recent low of $4.00. Under the rules of The
Nasdaq Stock Market, our stock price must remain above $1.00 per share for
continued quotation of our shares on the Nasdaq National Market. Stock price
volatility has had a substantial effect on the market prices of securities
issued by us and other high technology companies, often for reasons unrelated to
the operating performance of the specific companies. In the past, following
periods of volatility in the market price of a company's securities, securities
class action litigation has often been instituted against the company. We may in
the future be the target of similar litigation. Regardless of the outcome,
securities litigation may result in substantial costs and divert management
attention and resources.

IT MAY BE DIFFICULT TO ENFORCE JUDGMENTS AGAINST US IN U.S. COURTS.

Insignia is incorporated under the laws of England and Wales. Two of our
executive officers and two of our directors reside in England. All or a
substantial portion of the assets of these persons, and a significant portion of
our assets, are located outside of the United States. As a result, it may not be
possible for investors to effect service of process within the United States
upon these persons or to enforce against them or against us, in United States
courts, judgments obtained in United States courts predicated upon the civil
liability provisions of United States securities laws. There is doubt as to the
enforceability outside of the United States, in original actions or in actions
for enforcement of judgments of United States courts, of civil liabilities
predicated solely upon United States securities laws. In addition, the rights of
holders of our shares and, therefore, of the ADS holders, are governed by
English law, including the Companies Act 1985, and by our Memorandum and
Articles of Association. These rights differ from the rights of security holders
in typical United States corporations.

INSIGNIA HAS UNDERGONE A CLASS-ACTION LAWSUIT AND AN SEC INVESTIGATION IN THE
PAST FIVE YEARS.

On April 3, 1996, a class-action lawsuit was filed against us alleging that
we misrepresented the Company's business, the strength of its sales force and
its financial health. The suit stemmed from our failure to achieve the consensus
earnings estimates of research analysts in the first quarter following our
initial public offering in November 1995. In August 1997, we reached a
memorandum of understanding to settle the suits. Although we never agreed with
the allegations, we paid $8.0 million to the plaintiffs (of which our insurance
company paid $7.5 million).

In February 1997, we restated its financial results for the quarters ending
March 31 and June 30, 1996. We revised our revenue and net income numbers
downward for these two quarters due to

inflated revenues resulting from misstatement of inventory levels of one of our
resellers by two of our sales and marketing personnel. We agreed with the SEC to
cease and desist from engaging in similar accounting practices. The two Insignia
sales and marketing people involved in the revenue misstatement are no longer
with the Company and were forced to pay significant fines. Insignia did not have
to pay any fines.

THERE IS NO GUARANTEE THAT INSIGNIA WILL BE ABLE TO RECEIVE FUNDS CURRENTLY HELD
IN ESCROW.

An escrow was established in January 1998 under the agreements relating to
the purchase by Citrix of our NTRIGUE product line. Originally,
$8.75 million was deposited into the escrow as security for our indemnification
obligations. In August 1999, Citrix released $2.5 million of the escrow funds to
Insignia and made a claim estimated at a maximum amount of the remainder of the
funds, which was $6.25 million. The claim is based on an action that Citrix
filed against GraphOn Corporation in November 1998. The action seeks a
declaratory judgment that Citrix does not infringe any GraphOn rights and has
not misappropriated any GraphOn trade secrets. Citrix filed this action in
response to and to resolve assertions that we used GraphOn confidential
information to develop products, including the product line that we sold to
Citrix in February 1998. GraphOn did not file an action against either Insignia
or Citrix relating to its assertions. Insignia has filed an action against
Citrix for release of the escrow funds.

In February 2000 and September 2000, $1.0 million and $0.3 million,
respectively, were released from escrow to Insignia. There is currently $5.05
million still being held in escrow. There is a possibility that Insignia will
never be able to recover any of the funds in escrow.

CAUTIONARY NOTE ON FORWARD LOOKING STATEMENTS

This prospectus (including the documents incorporated by reference) contains
forward-looking statements regarding Insignia's plans, expectations, estimates
and beliefs. These statements involve risks and uncertainties, and actual
results could differ materially from those reflected in the forward-looking
statements. Forward-looking statements in this prospectus are typically
identified by words such as "believes," "anticipates," "expects," "intends,"
"will" and "may" and other similar expressions. In addition, any statements that
refer to expectations, projections or other characterizations of future events
or circumstances are forward-looking statements. Insignia will not necessarily
update the information in this prospectus if and when any forward-looking
statement later turns out to be inaccurate. Some of the important risks and
uncertainties that may affect our future results and performance are described
in "Risk Factors," above. Additional information about factors that could affect
our future results and events is included in our reports filed with the SEC and
incorporated by reference in this prospectus.

USE OF PROCEEDS

Insignia will not receive any of the proceeds from the sale of shares by the
selling security holders.

SELLING SECURITY HOLDERS

The number of ADSs that may actually be sold by each selling security holder
will be determined by the selling security holder. Because each selling security
holder may sell all, some or none of the ADSs that he or she holds, no precise
estimate can be given as to the number of ADSs that will be held by the selling
security holders at the termination of the offering.

The selling security holders have advised us that they are the beneficial
owners of the shares being offered.

PLAN OF DISTRIBUTION

We are registering the ADSs on behalf of the selling security holders. The
selling security holders acquired ADSs and warrants from Insignia on
February 12, 2001. This prospectus covers the ADSs they purchased on
February 12, 2001 and the ADSs we will issue upon exercise of warrants also
purchased on that date. To our knowledge, the selling security holders have not
entered into any agreement, arrangement or understanding with any particular
broker or market maker with respect to the sale of the shares covered by this
prospectus.

The selling security holders may offer and sell shares from time to time. In
addition, a selling security holder's donees, pledgees, transferees and other
successors in interest may sell shares received from a named selling security
holder after the date of this prospectus. The selling security holders will act
independently of Insignia in making decisions with respect to the timing, manner
and size of each sale. Sales may be made over the Nasdaq National Market or
otherwise, at the then prevailing market prices, at prices related to prevailing
market prices or at negotiated prices. The shares may be sold by one or more of
the following:

- a block trade in which the broker-dealer engaged by a selling security
holder will attempt to sell the shares as agent but may position and
resell a portion of the block as principal to facilitate the transaction;

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

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

The selling security holders have advised Insignia that they have not, as of
the date of this prospectus, entered into any agreements, understandings or
arrangements with any underwriters or broker-dealers for the sale of shares, nor
is there an underwriter or coordinating broker acting in connection with the
proposed sale of shares by the selling security holders.

In connection with distributions of the shares or otherwise, the selling
security holders may enter into hedging transactions with broker-dealers or
other financial institutions. In connection with these transactions,
broker-dealers or financial institutions may engage in short sales of the shares
in the course of hedging the positions they assume with selling security
holders. The selling security holders may also sell shares short and redeliver
the shares to close out these short positions. The selling security holders may
also enter into option or other transactions with broker-dealers or other
financial institutions that require the delivery to the broker-dealer or
financial institution of the shares, which the broker-dealer or financial
institution may resell or otherwise transfer under this prospectus. The selling
security holders may also loan or pledge the shares to a broker-dealer or other
financial institution and the broker-dealer or financial institution may sell
the shares so loaned or, upon a default, the broker-dealer may sell the pledged
shares under this prospectus. In addition, any securities covered by this
prospectus that qualify for sale under Rule 144 of the Securities Act may be
sold under Rule 144 rather than under this prospectus.

Transactions under this prospectus may or may not involve brokers or
dealers. The selling security holders may sell shares directly to purchasers or
to or through broker-dealers, who may act as agents or principals.
Broker-dealers engaged by the selling security holders may arrange for other
broker-dealers to participate in selling shares. Broker-dealers or agents may
receive compensation in the form of commissions, discounts or concessions from
the selling security holders in amounts to be negotiated in connection with the
sale. Broker-dealers or agents may also receive compensation in the form of
discounts, concessions or commissions from the purchasers of shares for whom the
broker-dealers may act as agents or to whom they sell as principal, or both.
This compensation as to a particular broker-dealer might exceed customary
commissions.

The selling security holders and any participating broker-dealers may be
deemed to be "underwriters" within the meaning of the Securities Act in
connection with sales of shares covered by this prospectus. Any commission,
discount or concession received by a broker-dealer and any profit on the resale
of shares sold by them while acting as principals might be deemed to be
underwriting discounts or commissions under the Securities Act. Because selling
security holders may be deemed to be underwriters within the meaning of the
Securities Act, the selling security holders will be subject to the prospectus
delivery requirements of the Securities Act.

Insignia has informed the selling security holders that the
anti-manipulation rules under the Exchange Act apply to sales of shares in the
market and to the activities of the selling security holders and their
affiliates. The selling security holders have advised Insignia that during the
time they may be engaged in the attempt to sell registered shares, they will:

- not engage in any stabilization activity in connection with any of
Insignia's securities;

- not bid for or purchase any of Insignia's securities or any rights to
acquire Insignia's securities, or attempt to induce any person to purchase
any of Insignia's securities or rights to acquire Insignia's securities,
other than, in each case, as permitted under the Exchange Act; and

- not sell or distribute the shares until after the prospectus has been
appropriately amended or supplemented, if required, to set forth the terms
of sale or distribution.

This offering will terminate on the earlier of:

- February 12, 2004; or

- the date on which all shares offered have been sold by the selling
security holders.

Insignia has agreed to pay the expenses of registering the shares under the
Securities Act, including registration and filing fees, printing expenses,
administrative expenses and certain legal and accounting fees. The selling
security holders will bear all discounts, commissions or other amounts payable
to underwriters, dealers or agents as well as fees and disbursements for legal
counsel retained by any selling security holder. The selling security holders
may agree to indemnify any agent, dealer or broker-dealer that participates in
transactions involving sales of shares against liabilities, including
liabilities arising under the Securities Act.

Upon the occurrence of any of the following events, a supplement to this
prospectus will be filed, if required, under Rule 424(b) under the Securities
Act to include additional disclosure before offers and sales of the securities
in question are made:

- to the extent the securities are sold at a fixed price or at a price other
than the prevailing market price, such price would be set forth in the
prospectus;

- if the securities are sold in block transactions and the purchaser acting
in the capacity of an underwriter wishes to resell, such arrangements
would be described in the prospectus;

- if the selling security holders sell to a broker-dealer acting in the
capacity as an underwriter, such broker-dealer will be identified in the
prospectus;

- if the compensation paid to broker-dealers is other than usual and
customary discounts, concessions or commissions, disclosure of the terms
of the transaction would be included in the prospectus; and

- if a selling security holder notifies Insignia that a donee or pledgee
intends to sell more than 500 shares.

LEGAL MATTERS

The validity, under English law, of the shares offered hereby will be passed
upon for Insignia by Macfarlanes, London.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

Insignia's Articles of Association contain a provision to the effect that,
so far as permitted by the statutory provisions of English law, Insignia shall
indemnify the directors and secretary against liabilities incurred by them in
relation to the affairs of Insignia. However, the Companies Act 1985 rendered
any such indemnity ineffective to the extent it applies to neglect or breach of
duty in relation to Insignia, except to the extent that it covers costs incurred
by the director or secretary in respect of court proceedings in which judgment
is given in his favor.

Insignia's policy is to enter into indemnity agreements with each of its
directors and executive officers. In addition, Insignia Solutions, Inc., a
Delaware corporation and a wholly owned subsidiary of Insignia, enters into
indemnity agreements with each of Insignia's directors and executive officers.
The indemnity agreements provide that directors and executive officers will be
indemnified and held harmless to the fullest possible extent permitted by law,
including against all expenses (including attorneys' fees), judgments, fines and
settlement amounts paid or reasonably incurred by them in any action, suit or
proceeding, including any derivative action by or in the right of Insignia, on
account of their services as directors, officers, employees or agents of
Insignia or as directors, officers, employees or agents of any other company or
enterprise when they are serving in such capacities at the request of Insignia.
Neither Insignia nor Insignia Solutions, Inc. will be obligated pursuant to the
agreements to indemnify or advance expenses to an indemnified party with respect
to proceedings or claims:

- initiated by the indemnified party and not by way of defense, except with
respect to a proceeding authorized by the board of directors and
successful proceedings brought to enforce a right to indemnification under
the indemnity agreements;

- for any amounts paid in settlement of a proceeding unless Insignia
consents to the settlement;

- on account of any suit in which judgment is rendered against the
indemnified party for an accounting of profits made from the purchase or
sale by the indemnified party of securities of Insignia under
Section 16(b) of the Exchange Act and related laws;

- on account of conduct by an indemnified party that is finally adjudged to
have been in bad faith or conduct that the indemnified party did not
reasonably believe to be in, or not opposed to, the best interests of
Insignia;

II-1

- on account of any criminal action or proceeding arising out of conduct
that the indemnified party has reasonable cause to believe was unlawful;
or

- if a final decision by a court having jurisdiction in the matter shall
determine that such indemnification is not lawful.

The indemnity agreements are not exclusive of any rights a director or
executive officer may have under the Articles of Association, other agreements,
any majority-in-interest vote of the shareholders or vote of disinterested
directors, applicable law or otherwise.

The indemnification provision in the Articles of Association, and the
indemnity agreements, may be sufficiently broad to permit indemnification of
Insignia's directors and executive officers for liabilities arising under the
Securities Act. In addition, Insignia has director and officer liability
insurance.

UNDERTAKINGS

The undersigned Registrant hereby undertakes:

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

(i) To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933 (the "Securities Act").

(ii) 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. Notwithstanding the foregoing, any increase or
decrease in volume or 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 offering price set
forth in the "Calculation of Registration Fee" table in the effective
registration statement.

(iii) 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.

(2) That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities

II-3

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.

(4) That, for purposes of determining any liability under the Securities
Act, each filing of the Registrant's annual report pursuant to
Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act") (and, where applicable, each filing of an employee
benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that
is incorporated by reference in this Registration Statement shall be deemed to
be a new registration statement relating to the securities offered herein, and
the offering of such securities at that time shall be deemed to be the initial
BONA FIDE offering thereof.

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

Pursuant to the requirements of the Securities Act of 1933, the registrant

requirements for filing on Form S-3 and has duly caused this Registration
