    The closing sales price of the Company's ADS as reported on the Nasdaq
National Market on February 22, 2001 was $5.00 per share. As of that date, there
were approximately 148 holders of record of the Company's Ordinary Shares and
ADSs, excluding holders of ADSs whose ADSs are held in nominee or street name by
brokers.

DIVIDENDS

    The Company has not declared or paid any cash dividends on its Ordinary
Shares. The Company anticipates that it will retain any future earnings for use
in its business and does not anticipate paying any cash dividends in the
foreseeable future. Any payment of dividends would be subject, under English
law, to the Companies Act 1985, and to the Company's Memorandum of Association,
and may only be paid from the retained earnings of the Company, determined on a
pre-consolidated basis. As of December 31, 2000 the Company had a deficit of
$18,922,507 on a pre-consolidated basis.

RECENT SALES OF UNREGISTERED SECURITIES

    On December 9, 1999, the Company entered into agreements whereby the Company
issued 1,063,515 Ordinary Shares in ADS form at a price of $4.23 per share to
Castle Creek Technology Partners LLC and four other investors of whom one is a
member of the Company's board of directors. The Company also issued warrants to
the purchasers to purchase a total of 319,054 ADSs at the price of $5.29 per
share. An issuance of ADSs and warrants on November 24, 2000 has had a dilutive
effect on the warrants, resulting in an increase in the number of ADSs issuable
to 353,834, and a decrease of the exercise price to $4.77. The issuance of ADSs
and warrants on February 12, 2001 also triggered the anti-dilution provisions.
However, the effect of such dilution was less than 1% of the exercise price, and
consequently such adjustment is deferred until such time as the accumulation of
the adjustments exceeds at least 1% of the exercise price. The warrants expire
on December 9, 2004. The Company received $4.5 million less offering expenses
totaling $0.4 million. The securities were issued by the Company in reliance
upon the exemption from registration provided under Rule 506 of Regulation D
promulgated under the Securities Act to five accredited investors in a
transaction not involving any public offering.

    During 2000, the Company issued a total of 19,994 Ordinary Shares in ADS
form at various prices, ranging from $6.281 to $16.50 to a director of the
Company, as payment for drawdown fees under a Line of Credit arrangement entered
into in March 2000. The securities were issued in reliance upon the exemption
from registration provided under Section 4 (2) of the Securities Act, based on
the fact that the shares were sold by the issuer in a sale not involving a
public offering.

    On November 24, 2000 the Company entered into agreements whereby the Company
issued 3,600,000 Ordinary Shares in ADS form at a price of $5.00 to a total of
23 investors, including Sun Microsystems, BSquare, and a member of the Company's
board of directors. The Company also issued warrants to purchase 1,800,000 ADSs
to the investors at an exercise price of the lower of the average quoted closing
sale price of the Company's ADSs for the ten trading days ending on the day
preceding the date of the warrant holder's intent to exercise less a 10%
discount, and $6.00. The warrants expire on November 24, 2003, however, subject
to certain conditions, if the quoted sale price of the ADSs exceed $9.00 per
share for any thirty consecutive trading days, the Company may cancel the
warrants upon sixty days prior written notice. The Company received
$18.0 million less offering expenses totaling $2.0 million. The Company also
issued warrants to purchase 225,000 ADSs to the placement agent exercisable at a
price of $5.00. These warrants expire on November 24, 2005. The securities were
issued by the Company in reliance upon the exemption from registration provided
under Rule 506 of Regulation D promulgated under the Securities Act to 23
accredited investors in a transaction not involving any public offering.

    On December 31, 2000 the Company issued a total of 251,333 Ordinary Shares
in ADS form to Quantum Peripherals (Europe) SA, at a per share price of $4.23
per share under the terms of a convertible promissory note entered into on
October 20, 1999. The securities were issued in reliance upon the exemption from
registration provided under Section 4 (2) of the Securities Act.

    On February 12, 2001 the Company entered into agreements whereby the Company
issued 940,000 Ordinary Shares in ADS form at a price of $5.00 to a total of 4
investors, including Wind River Systems, Inc., and a member of the Company's
board of directors. The Company also issued warrants to purchase 470,000 ADSs to
the investors at an exercise price of the lower of the average quoted closing
sale price of the Company's ADSs for the ten trading days ending on the day
preceding the date of the warrant holder's intent to exercise less a 10%
discount, and $6.00. The warrants expire on February 12, 2004, however, subject
to certain conditions, if the quoted sale price of the ADSs exceed $9.00 per
share for any thirty consecutive trading days, the Company may cancel the
warrants upon sixty days prior written notice. The Company received
$4.7 million less offering expenses totaling $0.5 million. The Company also
issued warrants to purchase 25,000 ADSs to the placement agent exercisable at a
price of $5.00. These warrants expire on February 12, 2006. The securities were
issued by the Company in reliance upon the exemption from registration provided
under Rule 506 of Regulation D promulgated under the Securities Act to four
accredited investors in a transaction not involving any public offering.

OVERVIEW

    Insignia Solutions plc (the "Company"), which commenced operations in 1986,
develops, markets and supports software technologies that speed the adoption of
Java-based individualized computing in Internet appliances and embedded devices.

    In January 1998, the Company announced its intention to launch a new product
line called the Jeode-TM- platform, based on the Company's Embedded Virtual
Machine ("EVM"-TM-) technology. This followed a strategic review in late 1997 of
the Company's business. The Company also explored new markets that would
leverage the Company's 15 years of emulation software development experience.
The Jeode platform is the Company's implementation of Sun Microsystems, Inc.'s
("Sun") Java-Registered Trademark- technology tailored for Internet appliances
and embedded devices. It leverages patent-pending intellectual property to
provide these resource-constrained devices with high performance,
fully-compatible Java applet and application support. The product became
available for sale in March 1999. The Jeode platform is now the principal
product line of the Company and will be for the foreseeable future. The Jeode
product line revenue model is based on original equipment manufacturer's
("OEMs") and channel partner's customer transactions.

    The Company's principal product line in recent years was SoftWindows-TM-.
This product enabled Microsoft Windows ("Windows"-Registered Trademark-)
applications to be run on most Apple Computer Inc.
("Apple"-Registered Trademark-) Macintosh computers and many UNIX workstations.
Revenues from this product line grew until 1995, but declined significantly
after that date, along with margins. This was due to a declining demand for
Apple Macintosh products and increased competition. In early 1999 Management
took steps to discontinue the product line, and on October 18, 1999, the Company
signed an exclusive licensing arrangement with FWB Software, LLC ("FWB"). This
arrangement allows the Company to focus exclusively on its Jeode platform
business strategy.

    Between December 1995 and May 1998, the Company shipped NTRIGUE-TM-, a
Windows compatibility client/server product that supported multiple X-terminals,
workstation clients, Macintosh computers, PCs, network computers and Net PCs
from a Windows NT-based server. The Company disposed of its NTRIGUE technology
in February 1998.

    The Company's operations outside of the United States are primarily in the
United Kingdom, where the majority of the Company's research and development
operations and its European sales activities are located. The Company
distributes its Jeode platform through OEM's and distributed its SoftWindows
product through independent distributors. The Company's revenues from customers
outside the United States are derived primarily from Europe and Asia and are
generally affected by the same factors as its revenues from customers in the
United States. The operating expenses of the Company's operations outside the
United States are mostly incurred in Europe and relate to its research and
development and European sales activities. Such expenses consist primarily of
ongoing fixed costs and consequently do not fluctuate in direct proportion to

    The Company operates with the United States dollar as its functional
currency, with a majority of revenues and operating expenses denominated in
dollars. Although the Company engages in short-term currency option and forward
exchange contracts in order to hedge short-term pound sterling net cash flows,
pound sterling exchange rate fluctuations against the dollar can cause United
Kingdom expenses, which are translated into dollars for financial statement
reporting purposes, to vary from period-to-period.

DISPOSAL OF NTRIGUE TECHNOLOGY

    On February 5, 1998 the Company completed the disposal of its NTRIGUE
technology to Citrix Systems Inc. ("Citrix") for $17.7 million. As part of the
disposal, the Company transferred 45 employees to Citrix, of which 43 were
development engineers.

    Under the terms of the disposal agreement $9.0 million was paid to the
Company in cash on February 5, 1998, and the remainder was being held in escrow
for the sole purpose of satisfying any obligations to Citrix arising from or in
connection with an event against which the Company would be required to
indemnify Citrix. Of this amount, $2.5 million, $0.9 million, $1.0 million and
$0.3 million were released to the Company in February 1999, August 1999,
February 2000 and September 2000, respectively.

    On January 29, 1999, the Company received an indemnity claim from Citrix
Systems, Inc. ("Citrix") for an amount estimated by Citrix to not exceed
$6.25 million. The claim was made in relation to the Asset Purchase Agreement
between the Company and Citrix under which Citrix purchased the Company's
NTRIGUE product line in February 1998.

    Citrix's indemnity claim is based on assertions made by GraphOn Corporation
("GraphOn") in January of 1998 and declaratory relief action that Citrix filed
against GraphOn in November 1998 in the United States District Court, Southern
District of Florida. Citrix's action against GraphOn seeks a declaratory
judgment that Citrix does not infringe any GraphOn proprietary rights and that
Citrix has not misappropriated any trade secrets or breached an agreement to
which GraphOn is a party. Citrix filed the action in response to and to resolve
assertions first made by GraphOn, and disclosed to Citrix in January 1998, that
the Company may have used GraphOn's confidential information to develop certain
of the Company's products, possibly including products the Company sold to
Citrix in February 1998. The Court dismissed the complaint, but Citrix has
subsequently filed an appeal. The Company believes that any misappropriation or
similar assertions by GraphOn are without merit or basis. Accordingly, the
Company contests Citrix's indemnity claim.

    On October 4, 1999, the Company filed a suit against Citrix and GraphOn in
the Superior Court of the State of California, County of Santa Clara, relating
to the misappropriation assertions of GraphOn's and Citrix's refusal to release
funds still remaining in escrow and breach of a Cooperation Agreement between
the parties. Subsequent to the filing of the lawsuit, Citrix agreed to release
$1.3 million from the escrow, leaving a balance of $5.1 million. GraphOn
answered the complaint, and claimed it had not made any claims of
misappropriation against the Company or Citrix. The case is pending.

    On March 15, 2000, GraphOn filed a suit against Citrix and the Company in
the Superior Court of the State of California, County of Santa Clara, alleging
trade secret misappropriation and breach of contract arising out of the same
facts and circumstances set forth in the Company's action against GraphOn. The
Company believes GraphOn's claims are without merit. The case is pending.

    The Jeode product line was the primary business of the Company for 2000. In
1999, the Company shipped two principal product lines: the Jeode platform and
SoftWindows.

    Revenue from the Jeode product line is derived from four main sources: the
sale of a development license, the sale of annual maintenance and support
contract/services, a commercial use royalty based on shipments of products that
include Jeode technology, and customer-funded engineering activities. The
Company derived its SoftWindows revenues from the sale of packaged software
products and annual maintenance contracts, along with royalties received from
bundling agreements with OEMs and customer-funded engineering activities under
OEM contracts. Revenues from the sale of development licenses, packaged products
and royalties received from OEMs are classified as license revenue, while
revenues from customer-funded engineering activities, training, and annual
maintenance contracts are classified as service revenue.

    In 2000 and 1999 Jeode platform revenues accounted for 98% and 23%,
respectively, of total revenues. The Jeode platform became available for sale in
1999 and generated no revenue in 1998. The Jeode platform is now the principal
product of the Company and will be the principal source of revenues for the
foreseeable future. The Jeode platform revenue increased 566% in 2000 compared
to 1999 as a result of increased demand. In 2000 and 1999 license revenue from
the sale of Jeode accounted for 83% and 23%, respectively, of total revenues.
Service revenue from the Jeode platform accounted for 17% and less than 1% of
total revenues for 2000 and 1999, respectively.

    In 2000, 1999 and 1998 total revenues from SoftWindows accounted for 2%, 74%
and 92%, respectively, of total Company revenues primarily due to reduced demand
for SoftWindows and management's decision to discontinue the product line. In
1999 and 1998, license revenue from the sale of the Company's products for
Macintosh computers accounted for 40% and 52% of total revenues, respectively.
UNIX total revenues declined 58% in 1999 compared to 1998 as a result of reduced
demand and Management's decision to discontinue the product line. In 1999 and
1998 total revenues from the Company's product for UNIX computers accounted for
34% and 40% of total revenues, respectively.

    On October 18, 1999, the Company signed an exclusive licensing arrangement
of its SoftWindows and RealPC product lines with FWB. The proceeds the Company
will receive from the license arrangement are based on an earn-out of FWB's
future revenues from the product lines and will be paid to the Company as those
revenues are achieved. Upon achieving a certain revenue threshold, the
SoftWindows and RealPC product lines will be transferred to FWB at no additional
consideration.

    In 2000, service revenues increased 386% compared to 1999. The increase is
due to providing customer-funded engineeing activities for the Jeode platform
and additional maintenance. Service revenues in 1999 declined 67% compared to
1998, primarily because the Company performed fewer customer-funded engineering
activities than in the previous year. Similarly, in 1998, service revenues
declined 48% compared to 1997.

    In 1998 total revenues from the Company's NTRIGUE products accounted for 7%
of total revenues. The NTRIGUE product line was sold in early 1998 and generated
no revenue in 1999.

<PAGE>
    Overall, total revenues and license revenues declined 51% and 50%,
respectively, in 1999 compared to 1998.

    The Company distributed its SoftWindows and RealPC packaged products within
the United States and internationally through distributors, resellers and
OEMs. The Company offered certain return privileges to its customers including
product exchange privileges and price protection. The Company recognized
revenues from packaged products upon shipment with provisions for estimated
future returns, exchanges and price protection being recorded as a reduction of
total revenues. A significant portion of the Company's revenue in 1997 was
derived from large OEM customer transactions, particularly in the UNIX and
NT-related product lines.

    Sales to distributors and OEM's representing more than 10% of total revenue
in each period accounted for the following percentages of total revenue.

    Sales to customers outside the United States, derived mainly from customers
in Europe and Asia, represented approximately 18%, 15% and 24% of total revenues
in 2000, 1999 and 1998, respectively. The Company markets Jeode to Internet
appliance and embedded device manufacturers in the United States, Europe and
Japan.

    Movements in currency exchange rates did not have a material impact on total
revenues in 2000, 1999 or 1998. Economic conditions in Europe and Japan, as well
as fluctuations in the value of the Euro and Japanese yen against the U.S.
dollar and British pound sterling, could impair the Company's 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.

</TABLE>

    Cost of license revenue is mainly comprised of royalties to third parties,
along with the costs of documentation, duplication and packaging. Cost of
service revenue includes costs associated with customer-funded engineering
activities and end-user support under maintenance contracts.

    The Company believes that the significant factors affecting the Jeode
platform gross margin include pricing of the development license, pricing of the
unit usage and royalties to third parties such as Sun Microsystems, Inc.
("Sun"). In early 1999, the Company signed a five-year agreement with Sun under
which Sun established the Company as an Authorized Virtual Machine Provider.
Under this agreement the Company will pay Sun a per unit royalty on each Jeode
platform-enabled Internet appliance or embedded device shipped by the Company's
customers, plus a royalty on all development licenses put in place between the
Company and its customers.

    License gross margins in 2000 increased to 69% from 49% in 1999, due to the
Jeode product line which accounted for 83% of total license revenues in 2000.
License gross margins in 1999 increased to 49% from 36% in 1998 due to the
introduction of the Jeode product line which accounted for 23% of total license
revenues in 1999. The prior year gross margin was lower as a result of
SoftWindows pricing strategies, increased third party royalties for SoftWindows
and high returns on the NTRIGUE product line. There were no sales of Jeode in
1998.

    Gross margin for service revenue is impacted by the level of and pricing
terms of customer funded engineering activities, which can vary from customer to
customer, from contract to contract and the level of maintenance contracts sold.
Service gross margins in 2000 were 74% compared to (38%) in 1999. The increase
is due to Jeode customer-funded engineering activities and maintenance
agreements. In 1999 and 1998, the Company earned little revenue from
customer-funded engineering activities. UNIX maintenance agreement revenue
declined in 1999 and 1998. The Company discontinued selling SoftWindows
maintenance in late 1999 as a result of the SoftWindows license arrangement with
FWB. The continued support of existing SoftWindows contracts with no renewal
revenue combined with the high cost of providing support under NTRIGUE
maintenance contracts resulted in the Company achieving service revenue gross
margins of (38%) and 5% in 1999 and 1998, respectively.

    In the event that Jeode licenses increase in future periods, service revenue
gross margins are expected to increase due to customer-funded engineering
activities and the required maintenance, and upgrade contracts for each Jeode
product sale.

    Sales and marketing expenses consist primarily of advertising and
promotional expenses, trade shows, personnel and related overhead costs, and
salesperson commissions. Sales and marketing expenses decreased in 2000 by 3%.
Sales and marketing expenses were reduced in the first half of the year and
began increasing the second half of the year due to staffing new hires. Sales
and marketing expenses decreased in 1999 by 30% as a result of reduced spending
on SoftWindows advertising programs and staffing. The Company anticipates sales
and marketing expenses to increase in 2001 as the Company continues to increase
its marketing and direct sales organization for its Jeode product line. The
Company has established a direct sales force in the United States, Europe and
Japan.

    Research and development expenses consist primarily of personnel costs,
overhead costs relating to occupancy and equipment depreciation. Research and
development expenses in 2000 were comparable to 1999. Research and development
expenses decreased in 1999 by 4% over 1998 as a result of reductions in
personnel. During all of 1999 and the last half of 1998, the Company invested
the majority of its development expense in its Jeode technology to accelerate
the release of this product. In accordance with Statement of Financial
Accounting Standards No. 86, software development costs are expensed as incurred
until technological feasibility is established, after which any additional costs
are capitalized. In 2000, 1999 and 1998, no development expenditures were
capitalized. Development costs are expected to increase in 2001 as the Company
further enhances its Jeode technology.

    General and administrative expenses consist primarily of personnel and
related overhead costs for finance, information systems, human resources and
general management. General and administrative expenses increased by 17% in 2000
over 1999 as a result of increased legal fees and a large reversal of bad debt
reserves in 1999 not repeated in 2000. Excluding the impact of the bad debt
reserve adjustment, general and administrative expenses increased by 3%. General
and administrative expenses decreased by 25% in 1999 over 1998 as a result of
reduced headcount and reduced legal fees and the bad debt reserve reversal.
General and administrative costs are not expected to change significantly in
2001 compared to 2000 but will increase.

    Other income (expense), net decreased from an expense of $93,000 in 1999 to
income of $124,000 in 2000 and primarily comprised foreign exchange gains
(losses) in both periods. Other income (expense), net decreased from income of
$14.9 million in 1998 to an expense of $93,000 in 1999. The 1998 income was a
result of the gain on disposal of the NTRIGUE product line of $14.7 million.
This gain comprised gross disposal proceeds of $17.7 million, less $3.0 million
of transaction expenses, employment terminations and costs and losses related to
the property and equipment sold or written down in value. Other expense is a
result of foreign exchange losses.

    Over 98% of the Company's total revenues and approximately 36% of its
operating expenses are denominated in United States dollars. Most of the
remaining revenues and expenses of the Company are British pound sterling
denominated and consequently the Company is exposed to fluctuations in British
pound sterling exchange rates. To hedge against this currency exposure, the
Company has, in prior years, entered into foreign currency options and forward
exchange contracts for periods and amounts consistent with the amounts and
timing of its anticipated British pound sterling denominated operating cash flow
requirements. Unrealized gains and losses on foreign currency option contracts
are deferred and were not material at December 31, 2000, 1999 and 1998. There
can be no assurance that such fluctuations will not have a material effect on
the Company's results of operations in the future.

    The Company has, at times, an investment portfolio of fixed income
securities that are classified as "available-for-sale-securities". These
securities, like all fixed income instruments, are subject to interest rate risk
and will fall in value if market interest rates increase. The Company attempts
to limit this exposure by investing primarily in short-term securities.

    The Company's benefit for income taxes for 2000 primarily represents a tax
refund from the United Kingdom government on taxes paid in the years
1995 - 1997. The Company's benefit for income taxes for 1999 primarily
represents certain non-U.S. taxes arising from sales to customers in Japan and
the benefit of offsetting net operating losses against provisions arising from
the disposal of the

Company's NTRIGUE product line in 1998. The Company recorded a tax provision in
1998 reflecting certain non-U.S. taxes arising upon the disposal of the
Company's NTRIGUE product line, net of offsetting operating losses.

    A more complete analysis of the differences between the federal statutory
rate and the Company's effective income tax rates is presented in Note 4 to the
Consolidated Financial Statements. At December 31, 2000, the Company has
recorded a full valuation allowance against all deferred tax assets, primarily
comprising net operating losses, on the basis that significant uncertainty
exists with respect to their realization.

    The Company has transitioned its product focus from compatibility products
to its Jeode product line based on the Company's EVM technology. This change in
product focus has resulted in a redirection of available resources from the
Company's historical revenue base towards the development and marketing efforts
associated with the Jeode platform, which was released for general availability
in March 1999. Cash used in operating activities totaled $11.4 million during
2000.

    The Company's cash, cash equivalents and short-term investments, including
restricted cash of $5.1 million held in escrow, were $17.3 million at
December 31, 2000, an increase of $6.2 million from $11.1 million at
December 31, 1999. Working capital increased to $11.7 million at December 31,
2000, from ($0.2) million at December 31, 1999. The principal source of cash
funding came from a private placement funding, a line of credit from a director,
receivable collections and NTRIGUE product line sales proceeds released from
escrow. Capital additions totaled $0.3 million, $0.2 million and $0.9 million
during the years ended December 31, 2000, 1999 and 1998, respectively.

    In February 1998, $8.9 million was received from the disposal of the NTRIGUE
product line. Additionally, $2.5 million, $0.9 million, $1.0 million and
$0.3 million were released to the Company in February 1999, August 1999,
February 2000 and September 2000, respectively, and the remaining $5.1 million
is being held in escrow pending resolution of the Citrix indemnity claim.

    On October 20, 1999, the Company signed a convertible promissory note in
favor of Quantum Corporation ("Quantum") for $1.0 million. The note is
convertible at Quantum's option to the Company's shares any time during the
lifetime of the note. All unpaid principal and unpaid interest, accrued at 8%
per annum, compounded quarterly, was converted to Ordinary Shares on
December 31, 2000.

    On March 20, 2000, the Company entered into a binding agreement with a
director whereby he would provide the Company a $5.0 million line of credit The
interest rate on amounts drawn down is at prime plus 2% until June 30, 2000 and
thereafter at prime plus 4% per annum simple interest, payable in cash at the
repayment date. The Company drew down a total of $3.0 million of the line of
credit during 2000. On November 27, 2000 the Company repaid this sum, along with
all accrued interest and the termination fee due.

    The Company believes the existing cash balances will be sufficient to meet
the Company's expected liquidity and capital needs for the coming year.

PRIVATE PLACEMENTS AND WARRANTS

    In a private placement that closed on November 24, 2000, certain investors
purchased from the Company a total of 3,600,000 units at a price of $5.00 per
unit. Each unit comprises one ADS and one half of one warrant to purchase one
ADS. As described below, the Company may cancel the warrants upon sixty days
prior written notice if the closing sale price of the Company's ADSs exceeds
$9.00 for 30 consecutive trading days following the effectiveness of a
registration statement filed with the Securities and Exchange Commission ("SEC")
for the ADSs issued and the ADSs underlying the warrants. This registration
statement became effective on December 24, 2000. As compensation for services in
connection with the private placement, the Company (i) issued five-year warrants
to purchase 225,000 of the Company's ADSs at an exercise price of $5.00 per
share, and (ii) paid a cash compensation equal to six percent (6%) of the gross
proceeds received by the Company in the private placement to the placement
agent.

    The investors that participated in this private placement received warrants
to purchase one ADS for every two ADSs they purchased. The exercise price of the
warrants was set at an exercise price per ADS equal to the lower of $6.00 and
the average quoted closing sale price of the Company's ADSs for the ten trading
days ending on the day preceeding the day the Company is informed of the
investor's intent to exercise, less a 10% discount. These warrants expire on
November 24, 2003.

    These investors also have rights under their subscription agreements to be
issued additional ADSs by the Company if the registration statement is suspended
for more than 60 days in any 12 month period by the Company. If the registration
statement is suspended beyond the 60 day limit, the Company must issue, for
payment of the nominal value of L0.20 per share, to these investors 0.07 ADS for
each ADS purchased in the private placement. In addition, the Company must
issue, for payment of the nominal value of L0.20 per share, 0.02 ADS for each
ADS purchased in the private placement for each month thereafter until the
suspension or stop order is lifted. If the Company issues additional ADSs under
these obligations, the ownership interest of existing shareholders will be
substantially diluted.

    In a private placement that closed on February 12, 2001, certain investors
purchased from the Company a total of 940,000 units at a price of $5.00 per
unit. Each unit comprises one ADS and one half of one warrant to purchase one
ADS. As described below, the Company may cancel the warrants upon sixty days
prior written notice if the closing sale price of the Company's ADSs exceeds
$9.00 for 30 consecutive trading days following the effectiveness of a
registration statement filed with the SEC for the ADSs issued and the ADSs
underlying the warrants. As compensation for services in connection with the
private placement, the Company (i) issued five-year warrants to purchase 25,000
of the Company's ADSs at an exercise price of $5.00 per share, and (ii) paid a
cash compensation equal to six percent (6%) of the first $2 million and 3% on
the remainder of the gross proceeds received by the Company in the private
placement to the placement agent.

    The investors that participated in this private placement received warrants
to purchase one ADS for every two ADSs they purchased. The exercise price of the
warrants was set at an exercise price per ADS equal to the lower of $6.00 and
the average quoted closing sale price of the Company's ADSs for the ten trading
days ending on the day preceeding the day the Company is informed of the
investor's intent to exercise, less a 10% discount. These warrants expire on
February 12, 2004.

    These investors also have rights under their subscription agreements to be
issued additional ADSs by the Company if (a) the Company does not register with
the SEC their ADSs and the ADSs underlying the Company's warrants and the SEC
does not declare the registration statement effective by May 14, 2001 or
(b) the registration statement is suspended for more than 60 days in any
12 month period by the Company. If the registration statement the Company files
with the SEC is not declared effective by the deadline, or if the registration
statement is suspended beyond the 60 day limit, the Company must issue, for
payment of the nominal value of L0.20 per share, to these investors 0.07 ADS

                                       13
<PAGE>
for each ADS purchased in the private placement. In addition, the Company must
issue, for payment of the nominal value of L0.20 per share, 0.02 ADS for each
ADS purchased in the private placement for each month thereafter until the
registration statement is declared effective by the SEC. If the Company issues
additional ADSs under these obligations, the ownership interest of existing
shareholders will be substantially diluted.

DILUTION ADJUSTMENTS

    In December 1999, the Company issued 1,063,515 Ordinary Shares in ADS form
at a price of $4.23 per share through a private placement. The Company received
$4.5 million less offering expenses totaling $0.4 million. Along with ADSs, the
Company also issued to the investors warrants that entitle them to purchase a
total of 319,054 ADSs at an exercise price of $5.29 per ADS. As described below,
the exercise price and the number of ADSs issuable under the warrants were
subject to potential adjustment.

    Under the December 1999 private placement, the investors received warrants
to purchase three ADSs for every 10 ADSs they purchased. The exercise price of
the warrants was set at 125% of the original per ADS purchase price, or $5.29.
However, the warrants contain anti-dilution provisions which decrease this
exercise price and increase the number of ADSs purchasable if the Company sells
or is deemed to sell any shares at below market price during the term of the
warrants, which ends on December 9, 2004. The private placement that closed on
November 24, 2000 was a sale which triggered the anti-dilution provisions in the
warrants, and, as a consequence, the exercise price of the warrants has been
decreased from $5.29 to $4.77 per ADS, and the number of ADSs purchasable has
increased to 353,834. The private placement on February 12, 2001 also triggered
the anti-dilution provisions of the issuance of December 9, 1999. However, the
effect of such dilution was less than 1% of the exercise price and consequently
such adjustment is deferred until such time as the accumulation of this
adjustment and future adjustments exceed at least 1% of the exercise price.

    As part of their warrant agreements, the investors may be entitled to cash
payments upon the occurrence of certain Major Transactions, as defined in the
warrant agreements, including change of control provisions. Cash payments are
determined in a methodology described in the agreement. Such methodology is
impacted by market price.

    Under the December 1999 private placement, the investors were entitled to
additional warrants to purchase ADS's at L0.20 nominal value per share if the
average of the closing bid price of the ADS's over the ten days before an
adjustment date was less than $4.23. The adjustment dates commenced on
March 10, 2000 and occurred on the 10th of each month through March 10, 2001,
inclusive. The rights for an adjustment date to occur would terminate upon
release of at least $4.75 million of the funds held in escrow by Citrix on
December 9, 1999. However, not enough of the funds held were released to trigger
this termination. The calculated average bid price of the Company's ADS's on all
the adjustment dates exceeded $4.23 per share and consequently no adjustment
occurred. The adjustment rights have now expired.

    The Company obtained a third-party valuation to allocate fair value to
amounts received from the private placement between the ADSs and the warrants.
In 1999 the amount allocated to mandatorily redeemable warrants totaled
$1.440 million, of which $0.590 million was allocated to the warrants, and
$0.850 million was allocated to the additional warrants. Of the remaining net
proceeds received, $2.619 million was allocated to mandatorily redeemable
capital. The $2.619 million of mandatorily redeemable capital was reclassed when
the registration statement for the ADSs and the ADSs underlying the warrants
issued in the December 1999 private placement became effective on March 28,
2000, of which $0.340 million was classified as Ordinary Shares and
$2.279 million was classified as additional paid-in capital.

                                       14
<PAGE>
    Limitations in the transaction agreements preclude these investors in
question from achieving certain levels of beneficial ownership. The securities
purchase agreement, the warrants and the additional warrants contain the
restriction that the Company may not issue and a selling investor may not
purchase, and the warrants and additional warrants may not be exercised for any
ADSs if doing so would cause such investor to beneficially own more than 9.9% of
the total ordinary shares in issue as determined in accordance with
section 13(d) of the Securities Exchange Act of 1934. Under the additional
warrants, if such investors are prohibited from exercising the additional
warrant as a result of the 9.9% restriciton, the selling investor may, at its
option and in addition to its other rights under the securities purchase
agreement and the warrant, retain the warrant or demand payment, in cash, from
the Company in an amount calculated by the Black-Scholes formula multiplied by
the number of ADSs for which the additional warrant was exercisable, without
regard to any limits on exercise. The restrictions on the levels of beneficial
ownership in these documents do not, however, restrict those investors from
exercising the warrants or additional warrants up to those limitations, selling
ADSs to decrease their level of beneficial ownership, and exercising the
warrants to receive additional ADSs. This could result in additional dilution to
the holders of the Company's ADSs and a potential decrease in the price of the
ADSs.

    Any significant downward pressure on the price of the Company's ADSs as a
result of the exercise of the warrants or additional warrants and the sale of
material amounts of the Company's ADSs could encourage short sales of the
Company's ADSs. Short sales could place further downward pressure on the price
of the Company's ADSs.

YEAR 2000 COMPLIANCE

    The Company believes that all of the Company's most current product releases
will not cease to perform nor generate incorrect or ambiguous data or results
solely due to a change in date to or after January 1, 2000, and will calculate
any information dependent on these dates in the same manner, and with the same
functionality, data integrity and performance, as these products did on or
before December 31, 1999. However, all of the Company's customers may not
implement the Year 2000 compliant release of the Company's products in a timely
manner, which could lead to failure of customer systems and product liability
claims against the Company. Even if the Company's products are Year 2000
compliant, the Company may, in the future, be subject to claims based on Year
2000 issues in the products of other companies or issues arising from the
integration of multiple products within a system. The costs of defending and
resolving Year 2000-related disputes, and any liability for Year 2000-related
damages, including consequential damages, could be significant. In addition,
Year 2000 failures could have a negative effect on the Company's competitive
position. If any of the Company's critical suppliers do not successfully and
timely achieve Year 2000 compliance, and the Company is unable to replace them
with new or alternate suppliers, our business would be disrupted.

NEW ACCOUNTING PRONOUNCEMENTS

    In September 1998, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standard No. 133 "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS 133"). SFAS 133 establishes accounting and
reporting standards for derivative instruments and for hedging activities. This
statement becomes effective for all fiscal quarters of fiscal years beginning
after June 15, 1999. In June 1999, the FASB issued Statement of Financial
Accounting Standard No. 137 "Accounting for Derivative Instruments--Deferral of
the Effect Date of SFAS Statement No. 133" ("SFAS 137"). SFAS 137 defers the
effective date of SFAS 133 until June 15, 2000. The Company will adopt SFAS 133
in 2001. The Company expects the adoption of SFAS 133 will not affect results of
operations.

    In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial
Statements". SAB 101 provides guidance for

                                       15
<PAGE>
revenue recognition under certain circumstances. The Company does not believe
SAB 101 will have a material impact on the financial statements.

    In March 2000, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 44 "Accounting for Certain Transactions Involving Stock
Compensation--an interpretation of APB Opinion No. 25". This interpretation has
provisions that are effective on staggered dates, some of which began after
December 15, 1998 and others that become effective after June 30, 2000. The
adoption of this interpretation did not have a material impact on the financial
statements.

POTENTIAL FLUCTUATIONS IN OPERATING RESULTS

    The Company's revenues, margins and operating results are subject to
quarterly and annual fluctuations due to a variety of factors, including demand
for the Company's products, acceptance and demand for Java technology in the
Internet appliance and embedded device markets, the volume and timing of orders
received during the quarter, the mix of and changes in customers to whom the
Company's 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 the Company or by the Company's competitors, changes in pricing,
buyouts of commercial use licenses, product life cycles, the level of the
Company's 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 the Company's products; and
extraordinary events, such as litigation, including related charges. Although
the Company's primary functional currency is the United States dollar, a
significant portion of the Company's operating expenses are incurred by its
United Kingdom operations and paid in British pound sterling. The Company enters
into short-term currency option and forward exchange contracts to hedge the
short-term impact of exchange rate fluctuations on British pound sterling net
operating cash flows, but there can be no assurance that such fluctuations will
not have a material adverse effect on the Company's business, financial
condition or results of operations in the future. A relatively high percentage
of the Company's expenses is fixed over the short term and, as a result, if
anticipated revenues in any quarter do not occur or are delayed, expenditure
levels could be disproportionately high as a percentage of total revenues and
the Company's operating results for that quarter would be adversely affected. It
is difficult for the Company 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. The Company's success depends upon the use of the
Company's technology by our licensees in their embedded systems, which makes it
difficult for the Company to predict when the Company will recognize royalty or
revenues from commercial use licenses. An increasing amount of the Company's
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 the Company's revenue recognition criteria, even if
it meets or exceeds the Company's forecast of aggregate licensing and other
contracting activity, it is possible that the Company's revenues would not meet
expectations. If sales forecasted from a specific customer for a particular
quarter are not realized in that quarter, the Company is unlikely to be able to
generate revenue from alternate sources in time to compensate for the shortfall.
As a result, and due to the relatively large size of some orders, a lost or
delayed sale could have a material adverse effect on the Company's quarterly
operating results. Moreover, to the extent that significant sales occur earlier
than expected, operating results for subsequent quarters may be adversely
affected. There can be no assurance that the Company will be able to achieve
profitability on a quarterly or annual basis. The Company intends to make a
significant investment in its marketing, sales, customer support and research
and development infrastructure to support its Jeode product line. The timing of
this expansion and the rate at which the Jeode platform generates revenue could
cause material fluctuations in the Company's results of operations. As a result,
the Company believes that period-to-period comparisons of its results of
operations are not necessarily meaningful and should not be relied upon as
indications

                                       16
<PAGE>
of future performance. Although historically the Company's business has not been
subject to seasonal variations, sales of the Company's products in certain
international markets, such as Europe, are typically slower in the summer
months. Due to all of the foregoing factors, it is possible that in some future
quarters the Company's operating results will be below the expectations of stock
market analysts and investors. In such event, the price of the Company's ADSs
would likely be materially adversely affected.

    The prices for the Company's ADSs have fluctuated widely in the past. During
the 12 months ended February 22, 2001, the closing price of a share of the
Company's common stock ranged from a high of $27.50 to a low of $4.25. Under the
rules of The Nasdaq Stock Market, the Company's stock price must remain above
$1.00 per share for continued quotation of the Company's shares on the Nasdaq
National Market. Stock price volatility has had a substantial effect on the
market prices of securities issued by the Company 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 been
instituted against the Company. The Company may in the future be the target of
similar litigation. Regardless of the outcome, securities litigation may result
in substantial costs and divert Management's attention and resources.

FUTURE OPERATING RESULTS

    Except for the historical information contained in this 10-K, the matters
discussed herein are forward-looking statements. These forward-looking
statements concern matters which include, but are not limited to, the revenue
model and market for the Jeode product line, the features, benefits and
advantages of the Jeode platform, international sales, gross margins, the
availability of licenses to third-party proprietary rights, business and sales
strategies, matters relating to proprietary rights, competition, Year 2000
compliance, exchange rate fluctuations and the Company's liquidity and capital
needs and other statements regarding matters that are not historical are
forward-looking statements. These matters involve risks and uncertainties that
could cause actual results to differ materially from those in the forward
looking statements. In addition to the factors discussed above, among other
factors that could cause actual results to differ materially are the following:
the demand for the Jeode platform; the performance and functionality of Jeode
technology; the Company's ability to deliver on time, and market acceptance of
new products or upgrades of existing products; the timing of, or delay in, large
customer orders; continued availability of technology and intellectual property
license rights; product life cycles; quality control of products sold;
competitive conditions in the industry; economic conditions generally or in
various geographic areas; and the risks listed from time to time in the reports
that the Company files with the SEC. There can be no assurance that the Company
will experience growth in revenues and net income in any particular period when
compared to prior periods. Any quarterly or annual shortfall in net revenues
and/or net income from the levels expected by securities analysts and
shareholders would result in a substantial decline in the trading price of the
Company's shares.

    The Company continues to face significant risks associated with the
successful execution of its new product strategy. These risks include, but are
not limited to continued technology and product development, introduction and
market acceptance of new products, changes in the marketplace, liquidity,
competition from existing and new competitors which may enter the marketplace
and retention of key personnel. Due to the generally longer sales cycles
expected to be associated with the Jeode platform, the Company does not
currently have accurate visibility of future order rates and demand for its
products generally. There can be no assurance that Jeode platform products will
achieve market acceptance.

    The Company has experienced operating losses in each quarter since the
second quarter of 1996. To achieve profitability, the Company will have to
increase its revenue significantly. The Company's ability to increase revenues
depends upon the success of our Jeode product line. The Jeode platform is

                                       17
<PAGE>
a relatively new product and it may not achieve market acceptance. If the
Company is unable to generate revenues from Jeode technology in the form of
development license fees, maintenance and support fees, commercial use royalties
and customer-funded engineering services, the Company's current revenue will be
insufficient to sustain its business.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

ORGANIZATION AND BUSINESS

    Insignia Solutions plc (the "Company"), which commenced operations in 1986,
develops, markets and supports software technologies that speed the adoption of
Java-based individualized computing in Internet appliances and embedded devices.

    In January 1998, the Company announced its intention to launch a new product
line called the Jeode-TM- platform, based on the Company's Embedded Virtual
Machine ("EVM"-TM-) technology. This followed a strategic review in late 1997 of
the Company's business. The Company also explored new markets that would
leverage the Company's 12 years of emulation software development experience.
The Jeode platform is the Company's implementation of Sun Microsystems, Inc.'s
("Sun") Java-Registered Trademark- technology tailored for Internet appliances
and embedded devices. It leverages patent-pending intellectual property to
provide these resource-constrained devices with high performance, fully-
compatible Java applet and application support. The product became available for
sale in March 1999. The Jeode platform is now the principal product line of the
Company and will be for the foreseeable future. The Jeode product line revenue
model is based on original equipment manufacturer's ("OEMs") and channel
partner's customer transactions.

    The Company's principal product line in recent years was SoftWindows-TM-.
This product enabled Microsoft Windows ("Windows"-Registered Trademark-)
applications to be run on most Apple Computer Inc.
("Apple"-Registered Trademark-) Macintosh computers and many UNIX workstations.
Revenues from this product line grew until 1995, but declined significantly
after that date, along with margins. This was due to a declining demand for
Apple Macintosh products and increased competition. In early 1999 Company
management took steps to discontinue the product line, and on October 18, 1999,
the Company signed an exclusive licensing arrangement with FWB Software, LLC
("FWB"). Under the arrangement FWB will pay the Company a royalty based on an
earn-out of FWB's future revenues from the product lines and the Company will be
paid as those revenues are achieved. Upon achieving a certain revenue threshold,
the SoftWindows and RealPC product lines will be transferred to FWB at no
additional consideration.

    The Company sold its NTRIGUE product line to Citrix Systems Inc. ("Citrix")
in February 1998. NTRIGUE was a Windows compatibility client/server product that
supported multiple X-terminals, workstation clients, Macintosh computers, PCs,
network computers and NetPCs from a Windows NT-based server.

    The principal markets for the Company's products are North America, Europe
and Asia. The Company distributes its products through multiple distribution
channels, including direct sales, distributors, resellers and original equipment
manufacturers.

BASIS OF PRESENTATION

    The Company follows accounting policies that are in accordance with
principles generally accepted in the United States of America. The Company
conducts most of its business in U.S. dollars. All amounts included in the
financial statements and in the notes herein are in U.S. dollars unless
designated "L", in which case they are in pounds sterling. The exchange rates
between the U.S. dollar and the pound sterling were $1.50, $1.60 and $1.67
(expressed in U.S. dollars per pound sterling) at December 31, 2000, 1999 and
1998, respectively.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
USE OF ESTIMATES

    The preparation of 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
reporting period. Actual results could differ from those estimates.

PRINCIPLES OF CONSOLIDATION

    The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiaries. All significant intercompany accounts and
transactions are eliminated in consolidation.

CASH, CASH EQUIVALENTS, AND RESTRICTED CASH

    The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents. Cash, cash equivalents,
and restricted cash at December 31, 2000 and 1999 are comprised of cash,
restricted cash and certificates of deposit. Restricted cash, including
$5.1 million of cash and cash equivalents held in escrow at December 31, 2000,
aggregated $5.4 million and $6.4 million at December 31, 2000 and 1999,
respectively. Of these amounts $0.4 million at December 31, 1999 and 1998 was
restricted due to obligations under service contracts. The release of the
balance is pending resolution of the indemnity claim from Citrix.

    Certificates of deposit aggregated $9.25 million and $1.0 million at
December 31, 2000 and 1999, respectively.

    The Company has classified all its securities as "available-for-sale." The
fair value of these securities, comprised primarily of certificates of deposit
with commercial banks, approximates cost. These securities mature within one
year.

REVENUE RECOGNITION

    During fiscal 2000, the Company primarily entered into license arrangements
for the sale of the Jeode product to OEM's and distributors. Prior to fiscal
2000, the Company's primary source of revenue was derived from packaged product
licensing fees for the sale of the Company's SoftWindows-TM- products. Service
revenues are derived from customer funded engineering activities, training and
annual maintenance contracts.

    Revenue from licenses are recognized when persuasive evidence of an
agreement exists, delivery of the product has occurred, the fee is fixed and
determinable, and collectibility is probable. For contracts with multiple
elements, and for which vendor-specific objective evidence of fair value for the
undelivered elements exists, the Company recognizes revenue for the delivered
elements using the residual method as prescribed by Statement of Position
No. 98-9, "Modification of SOP No. 97-2 with Respect to Certain Transactions".
If vendor-specific objective evidence does not exist for all undelivered
elements, all revenue is deferred until evidence exists, or all elements have
been delivered. Generally the Company has vendor-specific objective evidence of
fair value for the maintenance element of software arrangements based on the
renewal rates for maintenance in future years as specified in the contracts. In
such cases, the Company defers the maintenance revenue at the outset of the
arrangement and recognizes it ratably over the period, during which the
maintenance is to be provided, which

                                       28

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
generally commences on the date the software is delivered. Vendor-specific
objective evidence of fair value for the service element is determined based on
the price charged when those services are sold separately. The Company
occasionally enters into license agreements with extended payment terms.
Provided all other revenue criteria are met, revenue from these contracts is
recognized at the earlier of when the cash is received from the customer or the
payments become due and payable.

    The Company also enters into license agreements with OEMs which provide for
minimum guaranteed royalty payments throughout the term of the agreement.
Provided all other revenue criteria are met, minimum guaranteed royalty revenue
is recognized when the payments become due and payable. Royalty revenue that
exceed the minimum guarantees is recognized as reported.

    Revenue from OEMs for customer-funded engineering are recognized on a
percentage of completion basis, which is computed using the input measure of
labor cost. Revenues from training are recognized when the training is
performed.

    The Company does not grant return rights or price protection under license
agreements for its Jeode product. The Company did grant return rights and price
protection to certain resellers and distributors related to the sale of the
SoftWindows product line during 1998 and 1999. The Company provided sales return
allowances for distributor and resellers inventories of its SoftWindows products
and certain rights of return and price protection on unsold merchandise held by
those distributors and resellers. The Company provided sales returns allowances
based on the Company's historical rates of return and estimates of expected sell
through by distributors and resellers of its product.

    License revenue and services revenue on contracts involving significant
implementation, customization or services which are essential to the
functionality of the software is recognized over the period of each engagement,
using the percentage of completion method. Labor hours incurred is generally
used as the measure of progress towards completion.

    Payments from the sale of development licenses, royalties, customer funded
engineering activities, training and maintenance contracts received in advance
of revenue recognition are recorded as deferred revenue.

INVENTORIES

    Inventories, principally finished software products, manuals and related
supplies, are stated at the lower of cost or market value. Cost is determined
using the first-in, first-out method. Provisions are made in each period for
excess and obsolete inventories.

EQUIPMENT AND DEPRECIATION

    Property and equipment is recorded at cost. Depreciation is provided using
the straight-line method over the estimated useful lives which range from three
to four years or the lease term if shorter.

FOREIGN CURRENCY TRANSLATION

    The Company's primary functional currency for its non-U.S. operations is the
U.S. dollar. Certain monetary assets and liabilities of the non-U.S. operating
companies are denominated in local currencies (i.e. not the U.S. dollar). Upon a
change in the exchange rate between the non-U.S. currency and the

                                       29

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
U.S. dollar, the Company must remeasure the local non-U.S. denominated assets
and liabilities to avoid carrying unrealized gains or losses on its balance
sheet. Non-U.S. dollar denominated monetary assets and liabilities are
remeasured using the exchange rate in effect at the balance sheet date, while
nonmonetary items are remeasured at historical rates. Revenues and expenses are
translated at the average exchange rates in effect during each period, except
for those expenses related to balance sheet amounts which are translated at
historical exchange rates. Remeasurement adjustments and transaction gains or
losses are recognized in the income statement during the period of occurrence.
During its early years of existence, the Company used the pound sterling as the
functional currency for its non-U.S. operations. Accordingly, translation gains
and losses recognized during such periods have been included in the cumulative
currency translation adjustments account.

FOREIGN CURRENCY FINANCIAL INSTRUMENTS

    The Company enters into currency option contracts to hedge against exchange
risks associated with the pound sterling denominated operating expenses of its
U.K. operations. The gains and losses on these contracts are generally included
in the statement of operations when the related operating expenses are
recognized. At December 31, 2000 and 1999, there were no outstanding currency
options. From time to time, the Company also enters into short-term forward
exchange contracts. The Company generally does not use hedge accounting for the
forward exchange contracts. Such contracts are marked to market at period ends.
No forward exchange contracts were outstanding at December 31, 2000 and 1999.

SOFTWARE DEVELOPMENT COSTS

    The Company capitalizes internal software development costs incurred after
technological feasibility has been demonstrated. The Company defines
establishment of technological feasibility as the completion of a working model.
Such capitalized amounts are amortized commencing with the introduction of that
product at the greater of the straight-line basis utilizing its estimated
economic life, generally six months to one year, or the ratio of actual revenues
achieved to the total anticipated revenues over the life of the product. At
December 31, 2000 and 1999, capitalized software development costs were fully
amortized.

STOCK-BASED COMPENSATION

    The Company accounts for its employee stock option plans and employee stock
purchase plan in accordance with provisions of the Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25"), and
complies with the disclosure provision of Statement of Financial Accounting
Standards No. 123, "Accounting for Stock-Based Compensation" ("FAS 123") in
these notes to consolidated financial statements. Under APB No. 25, compensation
costs is determined based on the difference, if any, on the grant date between
the fair value of the Company's stock and the amount an employee must pay to
acquire the stock.

    Stocks, stock options, and warrants for stock issued to non-employees have
been accounted for in accordance with the provisions of SFAS 123 and Emerging
Issue Task Force Issue No. 96-18, ("EITF 96-18") "Accounting for Equity
Instruments That are Issued to Other Than Employees for Acquiring, or in
Conjunction with Selling, Goods and Services".

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
INCOME TAXES

    The Company accounts for income taxes under an asset and liability approach
that requires the recognition of deferred tax assets and liabilities for the
expected future tax consequences of events that have been recognized in the
Company's financial statements or tax returns. In estimating future tax
consequences, the Company generally considers all expected future events other
than enactments of changes in the tax law or rates.

CONCENTRATIONS OF RISK

    Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of cash, cash equivalents,
restricted cash, short-term investments and trade accounts receivable. The
Company places its cash, cash equivalents, restricted cash and short-term
investments primarily in bank accounts and certificates of deposit with high
credit quality financial institutions.

    The Jeode platform is the Company's principal product line for the
forseeable future and generated 98% of the Company's total revenues for 2000.

    The Company sells its products primarily to original equipment manufacturers
and distributors.   The Company performs ongoing credit evaluations of its
customers' financial condition and generally requires no collateral from its
customers. The Company maintains an allowance for uncollectible accounts
receivable based upon the expected collectibility of all accounts receivable. At
December 31, 2000, two customers accounted for 43% and 25%, respectively, of
gross trade receivables. At December 31, 1999, three customers accounted for
36%, 18% and 12%, respectively, of gross trade receivables.

    In the first quarter of 1999, the Company signed a five-year agreement with
Sun Microsystems, Inc. ("Sun"), under which Sun established the Company as a Sun
Authorized Virtual Machine provider. Under the agreement, the Company will pay
Sun a per unit royalty on each Jeode-enabled OEM product shipped by the
Company's customers, plus a royalty on all development licenses between the
Company and its customers. If the agreement with Sun terminates or expires
without renewal, the Company would not be able to market the Company's Jeode
product line.

ADVERTISING COSTS

    The Company expenses advertising costs as incurred. Advertising expense
totaled $0.2 million, $0.6 million, and $1.4 million for the years ended
December 31, 2000, 1999 and 1998, respectively.

COMPREHENSIVE INCOME

    Statement of Financial Accounting Standards No. 130, "Reporting
Comprehensive Income" ("FAS 130"), requires that all items recognized under
accounting standards as components of comprehensive earnings be reported in an
annual statement that is displayed with the same prominence as other annual
financial statements. FAS 130 also requires that an entity classify items of
other comprehensive earnings by their nature in an annual financial statement.
Comprehensive income, as defined, includes all changes in equity during a period
from non-owner sources.

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
NET INCOME (LOSS) PER SHARE

    Basic net income (loss) per share is computed using the weighted average
number of ordinary shares outstanding during the period. Diluted net income
(loss) per share is computed using the weighted average number of ordinary
shares and ordinary share equivalents outstanding during the period. Ordinary
equivalent shares consist of warrants and stock options (using the treasury
stock method). Ordinary equivalent shares are excluded from the computation if
their effect is antidilutive

RECLASSIFICATIONS

    Certain previously reported amounts have been reclassified to conform with
the current period presentation.

NEW ACCOUNTING PRONOUNCEMENTS

    In September 1998, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standard No. 133 "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS 133"). SFAS 133 establishes accounting and
reporting standards for derivative instruments and for hedging activities. This
statement becomes effective for all fiscal quarters of fiscal years beginning
after June 15, 1999. In June 1999, the FASB issued Statement of Financial
Accounting Standard No. 137 "Accounting for Derivative Instruments--Deferral of
the Effect Date of SFAS Statement No. 133" ("SFAS 137"). SFAS 137 defers the
effective date of SFAS 133 until June 15, 2000. In June 2000, the Financial
Accounting Standards Board issued SFAS 138, "Accounting for Derivative
Instruments and Hedging Activities--An Amendment of FASB Statement 133".
SFAS 138 amends the accounting and reporting standards for certain derivatives
and hedging activities such as net settlement contracts, foreign currency
transactions and intercompany derivatives. The Company will adopt SFAS 133 in
2001. The Company has not engaged in derivatives or hedging activities since
early 1998 and does not expect the adoption of SFAS 133 and SFAS 138 to have a
material impact on the financial position or results of operations.

    In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial
Statements". SAB 101 provides guidance for revenue recognition under certain
circumstances. The adoption of SAB 101 did not have a material impact on the
financial statements.

    In March 2000, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 44 "Accounting for Certain Transactions Involving Stock
Compensation--an interpretation of APB Opinion No. 25". This interpretation has
provisions that are effective on staggered dates, some of which began after
December 15, 1998 and others that become effective after June 30, 2000. The
adoption of this interpretation did not have a material impact on the financial
statements.

    In March 1995, the Company's shareholders adopted the 1995 Employee Share
Purchase Plan (the "Purchase Plan") with 275,000 Ordinary shares reserved for
issuance thereunder. On July 21, 1998 the number of shares reserved for issuance
was increased to 525,000. On May 27, 1999 the number was further increased to
900,000. On The Purchase Plan enables employees to purchase Ordinary shares at
approximately 85% of the fair market value of the Ordinary shares at the
beginning or end of each six month offering period. The Purchase Plan qualifies
as an "employee stock purchase plan" under section 423 of the U.S. Internal
Revenue Code. During 2000, 1999 and 1998 the Company issued 43,183, 171,453 and
128,103 shares under the Purchase Plan, respectively. At December 31, 2000 and
1999 approximately 346,979 and 390,162 ordinary shares were reserved for future
Purchase Plan issuances, respectively.

    At December 31, 2000, the Company had available net operating loss
carryforwards of approximately $29 million, $14 million and $10 million for U.S.
Federal, State and United Kingdom tax purposes, respectively. If unutilized,
these net operating loss carryforwards will completely expire in 2011, 2020 and
unlimited, respectively.   For U.S. federal and state tax purposes, a portion of
the Company's net operating loss carryforwards may be subject to certain
limitations on annual utilization in case of a change in ownership, as defined
by federal and state tax law.

    At December 31, 2000, the Company's deferred tax assets relate primarily to
its United States and United Kingdom operations. Management believes that, based
on such factors as recent and potential

fluctuations in operating results, it is more likely than not that the United
States and the United Kingdom operations will not generate sufficient future
taxable income, and thus a full valuation allowance has been recorded at
December 31, 2000. If the Company generates taxable income in future years, the
valuation allowance may be reduced, which correspondingly may reduce the
Company's tax provision.

NOTE 5--EMPLOYEE PENSION PLANS:

    The Company has a 401(k) plan covering all of its U.S. employees and a
defined contribution pension plan covering all its United Kingdom employees.
Under both of these plans, employees may contribute a percentage of their
compensation and the Company makes certain matching contributions. Both the
employees' and the Company's contributions are fully vested and nonforfeitable
at all times. The assets of both these plans are held separately from those of
the Company in independently managed and administered funds. The Company's
contributions to these plans aggregated $215,000 in 2000, $202,000 in 1999 and
$182,000 in 1998.

ROYALTY AGREEMENT

    In the first quarter of 1999, the Company signed a five-year agreement with
Sun Microsystems, Inc. ("Sun"), under which Sun established the Company as a Sun
Authorized Virtual Machine provider. The agreement also grants the Company
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, the Company will pay Sun a per unit royalty

royalty on all development licenses between the Company and its customers. If
the agreement with Sun terminates or expires without renewal, the Company would
not be able to market the Company's Jeode product line.

    The Company had a non-exclusive, worldwide license from Microsoft
("Microsoft Distribution Agreement") to reproduce, adapt and distribute the
currently available versions of Windows and MS-DOS that were included as a
component of the Company's SoftWindows products. The Company paid Microsoft a

NOTE 9--PRIVATE PLACEMENT AND WARRANTS:

RECENT SALES OF UNREGISTERED SECURITIES

    On December 9, 1999, the Company entered into agreements whereby the Company
issued 1,063,515 Ordinary Shares in ADS form at a price of $4.23 per share to
Castle Creek Technology Partners LLC and four other investors of whom one is a
member of the Company's board of directors. The Company also issued warrants to
the purchasers to purchase a total of 319,054 ADSs at the price of $5.29 per
share. The warrants expire on December 9, 2004. The Company received
$4.5 million less offering expenses totaling $0.4 million. The securities were
issued by the Company in reliance upon the exemption from registration provided
under Rule 506 of Regulation D promulgated under the Securities Act to five
accredited investors in a transaction not involving any public offering. An
issuance of shares and warrants on November 24, 2000 has had a dilutive effect
on the warrants issued in the December 9, 1999 placement, resulting in an
increase in the number of ADSs issuable to 353,834, and

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 9--PRIVATE PLACEMENT AND WARRANTS: (CONTINUED)
a decrease of the exercise price to $4.77. An issuance of shares and warrants on
February 12, 2001 also triggered the anti-dilution provisions of the placement
of December 9, 1999. However, the effect of such dilution was less than 1% of
the exercise price, and consequently such adjustment is deferred until such time
as the accumulation of this adjustment and future adjustments exceed at least 1%
of the exercise price.

    During 2000, the Company issued a total of 19,994 Ordinary Shares in ADS
form at various prices, ranging from $6.281 to $16.50 to a director of the
Company, as payment for drawdown fees under a Line of Credit arrangement entered
into in March 2000. The securities were issued in reliance upon the exemption
from registration provided under Section 4 (2) of the Securities Act.

    On November 24, 2000 the Company entered into agreements whereby the Company
issued 3,600,000 Ordinary Shares in ADS form at a price of $5.00 to a total of
23 investors, including Sun Microsystems, BSquare, and a member of the Company's
board of directors. The Company also issued warrants to purchase 1,800,000 ADSs
to the investors at an exercise price of the lower of the average quoted closing
sale price of the Company's ADS's for the ten trading days ending on the day
preceding the date of the warrant holder's intent to exercise less a 10%
discount, and $6.00. The warrants expire on November 24, 2003, however, subject
to certain conditions, if the quoted sale price of the ADSs exceed $9.00 per
share for any thirty consecutive trading days, the Company may cancel the
warrants upon sixty days prior written notice. The Company received
$18.0 million less offering expenses totaling $2.0 million. The Company also
issued warrants to purchase 225,000 ADSs to the placement agent exercisable at a
price of $5.00. These warrants expire on November 24, 2005. The securities were
issued by the Company in reliance upon the exemption from registration provided
under Rule 506 of Regulation D promulgated under the Securities Act to 23
accredited investors in a transaction not involving any public offering.

    On December 31, 2000 the Company issued a total of 251,333 Ordinary Shares
in ADS form to Quantum Peripherals (Europe) SA, at a per share price of $4.23
per share under the terms of a convertible promissory note entered into on
October 20, 1999. The securities were issued in reliance upon the exemption from
registration provided under Section 4 (2) of the Securities Act based on the
fact that the shares were sold by the issuer in a sale not involving a public
offering.

DILUTION ADJUSTMENTS

    In December 1999, the Company issued 1,063,515 Ordinary Shares in ADS form
at a price of $4.23 per share through a private placement. The Company received
$4.5 million less offering expenses totaling $0.4 million. Along with ADSs, the
Company also issued to the investors warrants that entitle them to purchase a
total of 319,054 ADSs at an exercise price of $5.29 per ADS. As described below,
the exercise price and the number of ADSs issuable under the warrants are
subject to various adjustments. In addition, the Company may issue additional
warrants that entitle the investors to purchase ADSs at the nominal value on
designated adjustment dates in the future.

    Under the December 1999 private placement, the investors received warrants
to purchase three ADSs for every 10 ADSs they purchased. The exercise price of
the warrants was set at 125% of the original per ADS purchase price, or $5.29.
However, the warrants contain anti-dilution provisions which decrease this
exercise price and increase the number of ADSs purchasable if the Company sells
or is deemed to sell any shares at below market price during the term of the
warrants, which ends on December 9, 2004. The private placement that closed on
November 24, 2000 was a sale which triggered the anti-dilution provisions in the
warrants, and, as a consequence, the exercise price of the warrants

                                       43

NOTE 9--PRIVATE PLACEMENT AND WARRANTS: (CONTINUED)
has been decreased from $5.29 to $4.77 per ADS, and the number of ADSs
purchasable has increased to 353,834. The private placement on February 12, 2001
also triggered the anti-dilution provisions of the issuance of December 9, 1999.
However, the effect of such dilution was less than 1% of the exercise price and
consequently such adjustment is deferred until such time as the accumulation of
this adjustment and future adjustments exceed at least 1% of the exercise price.

    As part of their warrant agreements, the investors may be entitled to cash
payments upon the occurrence of certain Major Transactions, as defined in the
warrant agreements, including change of control provisions. Cash payments are
determined in a methodology described in the agreement. Such methodology is
impacted by market price. A Major Transaction is defined as a merger,
reorganization, or sale of all or substantially all of the assets of the Company
in which the stockholders of the Company immediately prior to the transaction
possess less than 50% of the voting power of the surviving entity (or its
parent) immediately after the transaction.

    Under the December 1999 private placement, the investors were entitled to
additional warrants to purchase ADS's at L0.20 nominal value per share if the
average of the closing bid price of the ADS's over the ten days before an
adjustment date was less than $4.23. The adjustment dates commenced on
March 10, 2000 and occurred on the 10th of each month through March 10, 2001,
inclusive. The rights for an adjustment date to occur would terminate upon
release of at least $4.75 million of the funds held in escrow by Citrix on
December 9, 1999. However, not enough of the funds held were released to trigger
this termination. As calculated the average bid price of the Company's ADS's on
all the adjustment dates exceeded $4.23 per share and consequently no adjustment
occurred. The adjustment rights have now expired.

    The Company obtained a third-party valuation to allocate fair value to
amounts received from the private placement between the ADSs and the warrants.
In 1999 the amount allocated to mandatorily redeemable warrants totaled
$1.440 million, of which $0.590 million was allocated to the warrant, and
$0.850 million was allocated to the additional warrant. Of the remaining net
proceeds received, $2.619 million was allocated to mandatorily redeemable
capital. The $2.619 million of mandatorily redeemable capital was reclassed,
when the registration statement for the ADSs and the ADSs underlying the
warrants issued in the December 1999 private placement became effective on
March 28, 2000, of which $0.340 million was classified as Ordinary Shares and
$2.279 million was classified as additional paid-in capital.

    Amounts classified as warrants will remain outside of shareholders' equity
for the life of the warrant or until they are exercised, whichever occurs first.
This classification reflects certain potential cash payments that may occur,
should the Company complete a major transaction, such as a takeover, during the
life of the warrants.

    Limitations in the transaction agreements preclude these investors in
question from achieving certain levels of beneficial ownership. The securities
purchase agreement, the warrants and the additional warrants contain the
restriction that the Company may not issue and a selling investor may not
purchase, and the warrants and additional warrants may not be exercised for any
ADSs if doing so would cause such investor to beneficially own more than 9.9% of
the total ordinary shares in issue as determined in accordance with
Section 13(d) of the Securities Exchange Act of 1934. Under the additional
warrants, if such investors are prohibited from exercising the additional
warrant as a result of the 9.9% restriciton, the selling investor may, at its
option and in addition to its other rights under the securities purchase
agreement and the warrant, retain the warrant or demand payment, in cash, from
the Company in an amount calculated by the Black-Scholes formula multiplied by
the number of ADSs

for which the additional warrant was exercisable, without regard to any limits
on exercise. The restrictions on the levels of beneficial ownership in these
documents do not, however, restrict those investors from exercising the warrants
or additional warrants up to those limitations, selling ADSs to decrease their
level of beneficial ownership, and exercising the warrants to receive additional
ADSs. This could result in additional dilution to the holders of the Company's
ADSs and a potential decrease in the price of the ADSs.

NOTE 10--CONVERTIBLE PROMISSORY NOTE:

    On October 20, 1999, the Company signed a convertible promissory note in
favor of Quantum Corporation ("Quantum") for $1.0 million. The note is
convertible at Quantum's option to the Company's shares any time during the
lifetime of the note. The initial conversion price is $4.28 per share with
adjustment clauses for stock splits, reverse stock splits and certain offerings.
As a result of the private placement in December 1999 (see note 9) this
conversion price was adjusted to $4.23 per share on December 9, 1999. All unpaid
principal and unpaid interest, accrued at 8% per annum, compounded quarterly,
was converted to Ordinary Shares on December 31, 2000.

NOTE 11--NTRIGUE:

    On February 5, 1998 the Company completed the disposal of its NTRIGUE
technology to Citrix Systems Inc. ("Citrix") for $17.7 million. As part of the
disposal, the Company transferred 45 employees to Citrix, of which 43 were
development engineers. The net gain on the disposal was $14.8 million after
deducting $2.9 million of costs associated with the disposal. These costs
included mainly $1.1 million of fixed assets write down, $0.7 million of legal
and transactions costs, $0.3 million of relocation costs, $0.3 million of bonus
payout to leaving employees and $0.5 million of other accrued legal costs.

    Under the terms of the disposal agreement $9.0 million was paid to the
Company in cash on February 5, 1998, and the remainder is being held in escrow
for the sole purpose of satisfying any obligations to Citrix arising from or in
connection with an event against which the Company would be required to
indemnify Citrix. Of this amount, $2.5 million, $0.9 million, $1.0 million and
$0.3 million were released to the Company in February 1999, August 1999,
February 2000 and September 2000, respectively. The Company has recorded earned
interest of $159,000, $173,000, and $218,000 for the years ended December 31,
1998, 1999, and 2000, respectively, and such amounts were included in the
accounts held in escrow.

    On January 29, 1999, the Company received an indemnity claim from Citrix
Systems, Inc. ("Citrix") for an amount estimated by Citrix to not exceed
$6.25 million. The claim was made in relation to the Asset Purchase Agreement
between the Company and Citrix under which Citrix purchased the Company's
NTRIGUE product line in February 1998.

    Citrix's indemnity claim is based on assertions made by GraphOn Corporation
("GraphOn") in January of 1998 and declaratory relief action that Citrix filed
against GraphOn in November 1998 in the United States District Court, Southern
District of Florida. Citrix's action against GraphOn seeks a declaratory
judgment that Citrix does not infringe any GraphOn proprietary rights and that
Citrix has not misappropriated any trade secrets or breached an agreement to
which GraphOn is a party. Citrix filed the action in response to and to resolve
assertions first made by GraphOn, and disclosed to Citrix in January 1998, that
the Company may have used GraphOn's confidential information to develop certain
of the Company's products, possibly including products the Company sold to
Citrix in

February 1998. The Court dismissed the complaint, but Citrix has subsequently
filed an appeal. The Company believes that any misappropriation or similar
assertions by GraphOn are without merit or basis. Accordingly, the Company
contests Citrix's indemnity claim.

    On October 4, 1999, the Company filed a suit against Citrix and GraphOn in
the Superior Court of the State of California, County of Santa Clara, relating
to the misappropriation assertions of GraphOn's and Citrix's refusal to release
funds still remaining in escrow and breach of a Cooperation Agreement between
the parties. Subsequent to the filing of the lawsuit, Citrix agreed to release
$1.0 million from the escrow, leaving a balance of $5.1 million. GraphOn
answered the complaint, and claimed it had not made any claims of
misappropriation against the Company or Citrix. The case is pending.

    On March 15, 2000, GraphOn announced it had filed a suit against Citrix and
the Company in the Superior Court of the State of California, County of Santa
Clara, alleging trade secret misappropriation and breach of contract arising out
of the same facts and circumstances set forth in the Company's action against
GraphOn. The Company believes GraphOn's claims are without merit. The case is
pending.

    The Company is included with certain other litigation matters in the
ordinary course of business. In the opinion of management, the claims are
without merit and no provision has been made.

NOTE 12--LINE OF CREDIT:

    On March 20, 2000, the Company entered into a binding agreement with a
director whereby he would provide the Company a $5.0 million line of credit with
a commitment fee of four points based upon the total amount of the line and
drawdown/termination fee of two points for the first drawdown or termination.
The interest rate on amounts drawn down was at prime plus 2% until June 30, 2000
and thereafter at prime plus 4% per annum simple interest, payable in cash at
the repayment date. The Company drew down a total of $3.0 million of the line of
credit during 2000. A total of 19,994 Ordinary Shares in ADS form were issued to
the director as payment for drawdown fees under the line of credit arrangement.
On November 27, 2000 the Company repaid this sum, along with all accrued
interest and the termination fee due.

NOTE 13--SUBSEQUENT EVENTS (UNAUDITED):

    On February 12, 2001 the Company entered into agreements whereby the Company
issued 940,000 Ordinary Shares in ADS form at a price of $5.00 to a total of 4
investors, including Wind River Systems, Inc., and a member of the Company's
board of directors. The Company also issued warrants to purchase 470,000 ADSs to
the investors, at an exercise price of the lower of the average quoted closing
sale price of the Company's ADS's for the ten trading days ending on the day
preceding the date of the warrant holder's intent to exercise less a 10%
discount, and $6.00. The warrants expire on February 12, 2004, however, subject
to certain conditions, if the quoted sale price of the ADSs exceed $9.00 per
share for any thirty consecutive trading days, the Company may cancel the
warrants upon sixty days prior written notice. The Company received
$4.7 million less offering expenses totaling $0.5 million. The Company also
issued warrants to purchase 25,000 ADSs to the placement agent exercisable at a
price of $5.00. These warrants expire on February 12, 2006. The securities were
issued in reliance upon the exemption from registration provided under
Regulation D promulgated under the Securities Act.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors
and Shareholders of Insignia Solutions plc:

    In our opinion, the consolidated financial statements listed in the index
appearing under Item 14 (a) (1) and (2) of this Annual Report on Form 10-K
present fairly, in all material respects, the financial position of Insignia
Solutions plc and its subsidiaries (the "Company") at December 31, 2000 and 1999
and the results of their operations and their cash flows for each of the three
years in the period ended December 31, 2000, in conformity with generally
accepted accounting principles in the United States of America. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States of America, which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.
