                                PROXY STATEMENT
                                  MAY   , 1999
 
                            ------------------------
 
    This Proxy Statement is for holders of ordinary shares of 20p each and
holders of American Depositary Shares ("ADSs") evidenced by American Depositary
Receipts of Insignia Solutions plc, a company organized under the laws of
England and Wales. This proxy statement is furnished by the Board of Directors
of Insignia (the "Board") in connection with the solicitation of specific voting
instructions from holders of ADSs and proxies from holders of ordinary shares
for voting at the Annual General Meeting of Insignia to be held at Insignia
House, The Mercury Centre, Wycombe Lane, Wooburn Green, High Wycombe,
Buckinghamshire, HP10 0HH, United Kingdom, on         , May   , 1999 at
    p.m., local time. All proxies will be voted in accordance with the
instructions contained therein and, if no choice is specified, the person or
persons appointed as proxy will vote or abstain from voting, at their
discretion.
 
    At April   , 1999, Insignia had         ordinary shares outstanding and
entitled to vote, of which approximately     % were held in the form of ADSs.
Each ADS represents one Ordinary Share. A minimum of two persons holding
together not less than one-third of the ordinary shares in issue will constitute
a quorum for the transaction of business at the meeting. This proxy statement
and the accompanying form of Proxy were first mailed to shareholders on or about
April    , 1999. Attached beginning at page F-1 of this proxy statement is
Insignia's U.K. Statutory Directors' Report and Accounts for the year ended
December 31, 1998 prepared in compliance with the U.K. Companies Act 1985 (the
"Act"). In addition, the 1998 Annual Report and Form 10-K is enclosed with this
proxy statement.
 
                   VOTING RIGHTS AND SOLICITATION OF PROXIES
 
    Holders of ordinary shares entitled to attend and vote at the meeting may
appoint a proxy to attend and, on a poll of such holders, to vote in their
place. A proxy need not be a shareholder of Insignia. Voting will be by a poll
on all the resolutions to be considered. Holders of Insignia's ordinary shares
are entitled to one vote for each ordinary share held. Shares may not be voted
cumulatively.
 
    Proposals 2 through 8 in the notice are ordinary resolutions. Proposal 9 in
the notice is a special resolution. An ordinary resolution requires the
affirmative vote of a majority of the votes cast at the meeting. A special
resolution requires the affirmative vote of at least 75% of the votes cast at
the meeting. Insignia will tabulate all votes and will separately tabulate, for
each proposal, affirmative and negative votes, abstentions and broker non-votes.
Abstentions and broker non-votes will not be counted in determining the votes. A
form of proxy is enclosed which, to be effective, must be signed, dated and
deposited at the Registered Office of Insignia (Insignia House, The Mercury
Centre, Wycombe Lane, Wooburn Green, High Wycombe, Buckinghamshire, HP10 0HH)
not less than forty-eight hours before the time of the Meeting, together with
the power of attorney or other authority (if any) under which it is signed.
Holders of ADSs should complete and return the voting instruction form provided
to them in accordance with the instructions contained therein, so that it is
received on or before May   , 1999. The
 
                                       1
<PAGE>
close of business on April   , 1998 has been fixed as the record date for the
determination of the holders of ADSs entitled to provide voting instructions to
The Bank of New York, as depositary.
 
    Insignia will pay the expenses of soliciting proxies and voting
instructions. Following the original mailing of the proxies and other soliciting
materials, Insignia and/or its agents may also solicit proxies and voting
instructions by mail, telephone, telegraph or in person. Following the original
mailing of the proxies and other soliciting materials, Insignia will request
that brokers, custodians, nominees, The Bank of New York, as depositary, and
other record holders of Insignia's ordinary shares or ADSs forward copies of the
proxies and other soliciting materials to persons for whom they hold ordinary
shares or ADSs and request authority for the exercise of proxies and/or voting
instructions. In such cases, Insignia, upon the request of the record holders,
will reimburse such holders for their reasonable expenses.
 
                            REVOCABILITY OF PROXIES
 
    Any person signing a proxy in the form accompanying this proxy statement has
the power to revoke it any time prior to one hour before the commencement of the
meeting by written instrument delivered to Insignia stating that the proxy is
revoked, by attendance at the meeting and voting in person or by duly filing a
replacement proxy. Please note, however, that if a person's shares are held of
record by a broker, bank or other nominee and that person wishes to vote at the
meeting, the person concerned should ensure that the broker, bank or other
nominee duly appoints such person as its proxy in order that he or she may do
so.
 
     PROPOSAL 1:  RECEIPT OF U.K. STATUTORY DIRECTORS' REPORT AND ACCOUNTS
 
    At the meeting, shareholders will receive the U.K. statutory accounts of
Insignia in respect of the financial year ended December 31, 1998, together with
the Directors' and Auditors' reports relating to those accounts. It is a U.K.
legal requirement that the accounts and the reports are laid before the
shareholders of Insignia in general meeting, following which they will be
approved by and signed on behalf of the Board of Directors and delivered to
Companies House in the U.K. on or before July 31, 1999. Shareholders are not
being asked to vote on this proposal. The U.K. statutory Directors' Report and
Accounts are attached hereto beginning on page F-1.
 
             PROPOSAL 2:  RE-APPOINTMENT OF INDEPENDENT ACCOUNTANTS
 
    Insignia has selected PricewaterhouseCoopers as its U.K. statutory auditors
to perform the audit of Insignia's financial statements for 1999, and the
shareholders are being asked to ratify such selection. Following the merger of
Price Waterhouse and Coopers & Lybrand from July 1, 1998, Price Waterhouse
resigned as auditors in favour of the new firm, PricewaterhouseCoopers, and the
Board appointed PricewaterhouseCoopers to fill the casual vacancy created by the
resignation. Representatives of PricewaterhouseCoopers are expected to be
present at the meeting, will have the opportunity to make a statement at the
meeting if they desire to do so and are expected to be available to respond to
appropriate questions.
 
  THE BOARD RECOMMENDS A VOTE FOR THE RE-APPOINTMENT OF PRICEWATERHOUSECOOPERS
 
           PROPOSALS 3 AND 4:  ELECTION AND RE-ELECTION OF DIRECTORS
 
    At the meeting, shareholders will consider the election of Vincent S. Pino,
who was appointed as a director of Insignia during the year after the last
annual general meeting. Shareholders will also consider the re-election of
Albert E. Sisto, who retires by rotation.
 
    Insignia's Articles of Association stipulate that the minimum number of
directors is two, but do not set any maximum number. Directors may be elected by
the shareholders, or appointed by the Board, and
 
                                       2
<PAGE>
remain in office until they resign or are removed by the shareholders. In
addition, at each Annual General Meeting the third of the directors who have
been in office longest since their last election, as well as any directors
appointed by the Board during the preceding year, are required to resign and are
then considered for re-election, assuming they wish to stand for re-election. Of
the current directors, Nicholas, Viscount Bearsted will be considered for
re-election in 2000 and Richard M. Noling and Albert E. Sisto will be considered
for re-election in 2001, assuming no additional directors are appointed by the
Board during the year. In the election of directors, each shareholder is
entitled on a poll to one vote for each Ordinary Share held. Shares may not be
voted cumulatively.

  THE BOARD RECOMMENDS A VOTE FOR THE ELECTION AND RE-ELECTION OF EACH OF THE
                              NOMINATED DIRECTORS
 
        PROPOSAL NO. 5:  AMENDMENT OF 1995 EMPLOYEE SHARE PURCHASE PLAN
 
    Shareholders are being asked to approve an amendment to Insignia's 1995
Employee Share Purchase Plan (the "Share Purchase Plan") to increase the number
of ordinary shares reserved for issuance thereunder by 375,000 shares, from
525,000 shares to 900,000 shares. The Board believes that the increase in the
number of shares reserved for issuance under the Share Purchase Plan is in the
best interests of Insignia because of the continuing need to provide equity
participation to attract and retain quality employees and remain competitive in
the industry. The Share Purchase Plan plays an important role in Insignia's
efforts to attract and retain employees of outstanding ability.
 
    The Board approved the proposed amendment in April 1999, to be effective
upon shareholder approval. Below is a summary of the principal provisions of the
Share Purchase Plan, assuming shareholder approval of the amendment. The summary
is not necessarily complete, and reference is made to the full text of the Share
Purchase Plan.
 
SHARE PURCHASE PLAN HISTORY
 
    The Share Purchase Plan, covering 275,000 shares, was adopted by the Board
in February 1995 and approved by the shareholders in March 1995. An amendment
increasing the number of shares reserved for issuance under the Share Purchase
Plan to 525,000 shares was adopted by the Board in April 1998 and approved by
the shareholders in July 1998. The purpose of the Share Purchase Plan is to
provide employees of Insignia designated by the Board as eligible to participate
("Participating Employees") with a convenient means to acquire an equity
interest in Insignia through payroll deductions and to provide an incentive for
continued employment.
 
    As of December 31, 1998, approximately 98 persons were eligible to
participate in the Share Purchase Plan, 338,385 shares had been issued pursuant
to the Share Purchase Plan and 186,615 shares were available for future issuance
under the Share Purchase Plan. Since inception of the Share Purchase Plan, three
executive officers of Insignia, George Buchan, Richard M. Noling, and Stephen M.
Ambler
 
                                       5
<PAGE>
purchased 18,717, 17,052, and 883 shares, respectively, pursuant to the Share
Purchase Plan. Over the term of the Share Purchase Plan through December 31,
1998, all employees as a group, other than executive officers, have purchased an
aggregate of 301,733 shares under the Share Purchase Plan. The closing price of
Insignia's ADSs on the Nasdaq National Market on April   , 1999 was $      per
share.
 
SHARES SUBJECT TO PURCHASE
 
    The shares subject to purchase under the Share Purchase Plan consist of
900,000 ordinary shares. This number of shares is subject to proportional
adjustment to reflect consolidation or subdivision of ordinary shares and other
similar events.
 
ADMINISTRATION
 
    The Share Purchase Plan is administered by the Compensation Committee of the
Board. The interpretation or construction by the Compensation Committee of any
provisions of the Share Purchase Plan or of any right granted under it is final
and binding on all Participating Employees.
 
ELIGIBILITY
 
    All employees of Insignia, or any parent or subsidiary of Insignia, are
eligible to participate in an Offering Period (as defined below) under the Share
Purchase Plan except the following: (a) employees who are not employed by
Insignia, or any parent or subsidiary, on the 15th day of the month before the
beginning of an Offering Period; (b) employees who are customarily employed for
less than 20 hours per week; (c) employees who are customarily employed for less
than five months in a calendar year; or (d) employees who, together with any
other person whose shares would be attributed to such employee pursuant to
Section 424(b) of the Internal Revenue Code of 1986, as amended (the "Code"),
own shares or hold options to subscribe for shares or who, as a result of
participation in the Share Purchase Plan, would own shares or hold options to
subscribe for shares possessing 5% or more of the total combined voting power or
value of all classes of shares of Insignia.
 
    Participating Employees participate in the Share Purchase Plan through
payroll deductions. A Participating Employee sets the rate of such payroll
deductions, which may not be less than 2% nor more than 10% of the Participating
Employee's W-2 compensation (in the case of employees in the United States).
Compensation for this purpose includes, but is not limited to, base salary,
wages, commissions, overtime, shift premiums (or the substantial equivalent
thereof for employees outside of the United States), bonuses and draws,
unreduced by the amount by which the Participating Employee's salary is reduced
pursuant to Sections 125 or 401(k) of the Code, not to exceed $25,000 per year
or such lower limit as set by the Compensation Committee.
 
    Each offering under the Share Purchase Plan is for a period of six months
(the "Offering Period"). The Offering Periods commence on February 1 and August
1 of each year and end on July 31 and January 31, respectively, of each year.
The first day of each Offering Period is the "Offering Date" for such Offering
Period. A Participating Employee cannot participate simultaneously in more than
one Offering Period. The Board has the power to determine the dates of Offering
Periods or change the duration of Offering Periods without shareholder approval.
 
    Participating Employees may elect to participate in any Offering Period by
enrolling as provided under the terms of the Share Purchase Plan. Once enrolled,
a Participating Employee will automatically participate in each succeeding
Offering Period unless the Participating Employee withdraws from the Offering
Period or the Share Purchase Plan is terminated. After the rate of payroll
deductions for an Offering Period has been set by a Participating Employee, that
rate continues to be effective for the remainder of the Offering Period (and for
all subsequent Offering Periods in which the Participating Employee is
automatically enrolled) unless otherwise changed by the Participating Employee.
The Participating Employee may increase or lower the rate of payroll deductions
for any subsequent Offering
 
                                       6
<PAGE>
Period, but may only lower the rate of payroll deductions for an ongoing
Offering Period. Not more than one change may be made during a single Offering
Period.
 
PURCHASE PRICE
 
    The purchase price per share at which an Ordinary Share may be acquired in
any Offering Period under the Share Purchase Plan is 85% of the lesser of (a)
the fair market value of a share on the Offering Date or (b) the fair market
value of a share on the last day of the Offering Period. The fair market value
of a share is the closing price of Insignia's ADSs on the Nasdaq National Market
on the date of determination.
 
PURCHASE OF SHARES UNDER THE SHARE PURCHASE PLAN
 
    The number of whole shares a Participating Employee will be able to purchase
in any Offering Period is determined by dividing the total amount withheld from
the Participating Employee during the Offering Period pursuant to the Share
Purchase Plan by the purchase price for each share determined as described
above. The purchase takes place automatically on the last day of the Offering
Period. Unless otherwise determined by the Board, no more than 200% of the
number of shares determined by using 85% of the fair market value of a share on
the Offering Date as the denominator may be purchased by an employee
participating in the Share Purchase Plan on the last day of any Offering Period.
At any time prior to 30 days before the commencement of an Offering Period, the
Board may set a lower maximum number of shares which may be purchased by any
Participating Employee on the last day of an Offering Period.
 
WITHDRAWAL
 
    A Participating Employee may withdraw from any Offering Period, provided
such withdrawal is made at least 15 days before the end of the Offering Period.
No further payroll deductions for the purchase of shares will be made for the
succeeding Offering Period unless the Participating Employee enrolls in the new
Offering Period in the same manner as for initial participation in the Share
Purchase Plan.
 
AMENDMENT OF THE SHARE PURCHASE PLAN
 
    The Board may at any time amend, terminate or extend the term of the Share
Purchase Plan, except that any such termination cannot affect the terms of
shares previously granted under the Share Purchase Plan, nor may any amendment
make any change in the terms of shares previously granted which would adversely
affect the right of any participant, nor may any amendment be made without
shareholder approval if such amendment would: (a) increase the number of shares
that may be issued under the Share Purchase Plan; (b) change the designation of
the employees (or class of employees) eligible for participation in the Share
Purchase Plan; or (c) constitute an amendment for which shareholder approval is
required to comply with any applicable securities laws.
 
TERM OF THE SHARE PURCHASE PLAN
 
    The Share Purchase Plan will continue until the earlier to occur of: (a)
termination of the Share Purchase Plan by the Board; (b) the issuance of all the
shares reserved for issuance under the Share Purchase Plan; or (c) February
2005, ten years after the date the Board adopted the Share Purchase Plan.
 
UNITED STATES FEDERAL INCOME TAX INFORMATION
 
    The following is a general summary as of the date of this proxy statement of
the United States federal income tax consequences to Insignia and Participating
Employees. The federal tax laws may change and the federal, state and local tax
consequences for any Participating Employee will depend upon his or her
individual circumstances. Each Participating Employee is encouraged to seek the
advice of a qualified tax advisor regarding the tax consequences of
participation in the Share Purchase Plan. The following
 
                                       7
<PAGE>
discussion does not purport to describe income tax consequences or tax
consequences for Participating Employees in countries other than the United
States.
 
    The Share Purchase Plan is intended to qualify as an "employee stock
purchase plan" within the meaning of Section 423 of the Code.
 
    Tax TREATMENT OF THE PARTICIPATING EMPLOYEE. Participating Employees will
not recognize income for federal income tax purposes either upon enrollment in
the Share Purchase Plan or upon the purchase of shares. All tax consequences are
deferred until a Participating Employee sells the shares, disposes of the shares
by gift or dies.
 
    If shares are held for more than one year after the date of purchase and
more than two years from the beginning of the applicable Offering Period, or if
the Participating Employee dies while owning the shares, the Participating
Employee realizes ordinary income on a sale (or a disposition by way of gift or
upon death) to the extent of the lesser of (i) 15% of the fair market value of
the shares at the beginning of the Offering Period or (ii) the actual gain (the
amount by which the market value of the shares on the date of sale, gift or
death exceeds the purchase price). All additional gain upon the sale of the
shares is treated as capital gain. If the shares are sold and the sale price is
less than the purchase price, there is no ordinary income and the Participating
Employee has a capital loss for the difference between the sale price and the
purchase price.
 
    If the shares are sold or are otherwise disposed of including by way of gift
(but not death, bequest or inheritance) (in any case a "disqualifying
disposition") within either the one-year or the two-year holding periods
described above, the Participating Employee realizes ordinary income at the time
of sale or other disposition, taxable to the extent that the fair market value
of the shares at the date of purchase is greater than the purchase price. This
excess will constitute ordinary income (currently not subject to withholding) in
the year of the sale or other disposition even if no gain is realized on the
sale or if a gratuitous transfer is made. The difference, if any, between the
proceeds of the sale and the aggregate fair market value of the shares at the
date of purchase is a capital gain or loss. The maximum tax rate applicable to
ordinary income is 39.6%. Long-term capital gain is taxed at a maximum rate of
20%. To receive long-term capital gain treatment, the shares must be held for
more than one year. Capital gains may be offset by capital losses and up to
$3,000 of capital losses may be offset annually against ordinary income.
 
    TAX TREATMENT OF INSIGNIA.  Insignia will be entitled to a deduction in
connection with the disposition of shares acquired under the Share Purchase Plan
only to the extent that the Participating Employee recognizes ordinary income on
a disqualifying disposition of the shares. Insignia will treat any transfer of
record ownership of shares as a disposition, unless it is notified to the
contrary. In order to enable Insignia to learn of disqualifying dispositions and
ascertain the amount of the deductions to which it is entitled, Participating
Employees will be required to notify Insignia in writing of the date and terms
of any disposition of shares purchased under the Share Purchase Plan.
 
UNITED KINGDOM INCOME TAX INFORMATION
 
    The following is a general summary as of the date of this proxy statement of
the United Kingdom income tax consequences for Participating Employees who are
resident or are ordinarily resident in the United Kingdom and who ordinarily
perform all or part of the duties of their employment in the United Kingdom.
Because the tax laws may change and because income tax consequences may vary
depending upon the particular circumstances of each Participating Employee, each
Participating Employee should consult his or her own tax advisor regarding the
income tax consequences of participation in the Share Purchase Plan. The
following discussion does not purport to describe income tax consequences or tax
consequences for Participating Employees in countries other than the United
Kingdom.
 
                                       8
<PAGE>
    Participating Employees are liable to be assessed to income tax on the
difference between the fair market value of the shares at the time they acquire
the shares and the actual discounted purchase price paid for the shares. This
income tax due will be collected under the PAYE system. Upon resale of the
shares acquired pursuant to the Share Purchase Plan, Participating Employees may
be liable to pay capital gains tax on the difference between the market value of
the shares on the date they are acquired and the price at which the
Participating Employee disposed of such shares. However, if a Participating
Employee disposes of the shares by way of gift or a sale for less than their
market value to a "connected person" being the Participating Employee's spouse,
a relative of the Participating Employee or the Participating Employee's spouse
or the spouse of any such relative, then for the purposes of assessing capital
gains tax liability, the Participating Employee will be deemed to have disposed
of the shares at the market value on the date of disposal.
 
    For Offering Periods commencing prior to April 5, 1999, a Participating
Employee will also be liable to pay employee national insurance contributions on
all or part of the amount of the discount of the purchase price to market value
of the shares on the Offering Date if the Participating Employee's earnings have
not reached the maximum employee national insurance contributions' threshold.
For Offering Periods commencing after April 5, 1999, a Participating Employee
will be liable to pay employee national insurance contributions on all or part
of the gain such Participating Employee receives at the time the shares are
acquired, if the Participating Employee's earnings have not reached the maximum
employee national insurance contributions' threshold.
 
ERISA
 
    The Share Purchase Plan is not subject to any of the provisions of the
Employee Retirement Income Security Act of 1974 ("ERISA") and is not qualified
under Section 401(a) of the Code.
 
NEW PLAN BENEFITS
 
    The amounts of future share purchases under the Share Purchase Plan are not
determinable because, under the terms of the Share Purchase Plan, purchases are
based upon elections made by Participating Employees. Future purchase prices are
not determinable because they are based upon the fair market value of Insignia's
ordinary shares.
 
                THE BOARD RECOMMENDS A VOTE FOR THE AMENDMENT OF
                            THE SHARE PURCHASE PLAN
 
PROPOSALS 6 AND 7:  AMENDMENT OF THE U.K. EMPLOYEE SHARE OPTION SCHEME 1996 AND
              1995 INCENTIVE STOCK OPTION PLAN FOR U.S. EMPLOYEES
 
    Shareholders are being asked to approve amendments to the 1995 Stock Option
Plan for U.S. Employees (the "1995 Plan") and the U.K. Employee Share Option
Scheme 1996 (the "1996 Scheme") to increase the number of ordinary shares
reserved for issuance thereunder by 750,000 shares, from 3,922,071 shares to
4,672,071 shares. The Board believes that the increase in the number of shares
reserved for issuance under these option plans is in the best interests of
Insignia because of the continuing need to provide share options to attract and
retain quality employees and remain competitive in the industry. The Board
believes that the granting of share options plays an important role in
Insignia's efforts to attract and retain employees of outstanding ability. The
Board believes that the additional reserve of shares with respect to which
options may be granted will provide Insignia with adequate flexibility to ensure
that Insignia can continue to aim for those goals and facilitate Insignia's
expansion of its employee base.
 
    Insignia initially reserved an aggregate of 3,372,071 Ordinary Shares for
issuance under all of Insignia's employee share option plans. An increase in the
number of shares reserved for issuance under the share option plans to 3,922,071
was adopted by the Board in April 1997 and approved by the shareholders in May
1997. Any shares that would have been issuable upon exercise of options granted
 
                                       9
<PAGE>
pursuant to any of Insignia's employee share option plans that expire or become
unexercisable for any reason without having been exercised in full will become
available for grant under the 1995 Plan or the 1996 Scheme (collectively, the
"Option Plans"). As of December 31, 1998, approximately 98 persons were eligible
to receive options under the Option Plans. At that date, under the Option Plans,
1,196,927 shares had been issued upon exercise of options, 2,272,133 shares were
subject to outstanding options and 453,011 shares were available for future
option grants, after taking into account any shares issuable upon exercise of
options under any of Insignia's employee share option plans that have expired or
become unexercisable without having been exercised in full and that have become
available for future option grants under the Option Plans. The closing price of
Insignia's ADSs on the Nasdaq National Market on        , 1999 was $     per
share.
 
    The Board approved the proposed amendment in April 1999, to be effective
upon shareholder approval. Below is a summary of the principal provisions of the
Option Plans, assuming shareholder approval of the amendment. The summary is not
necessarily complete, and reference is made to the full text of the Option
Plans.
 
                     U.K. EMPLOYEE SHARE OPTION SCHEME 1996
 
1996 SCHEME HISTORY
 
    The 1996 Scheme was adopted by the Board in March 1996 and approved by the
shareholders in April 1996. The purpose of the 1996 Scheme is to attract, retain
and provide equity incentives to selected persons to promote the financial
success of Insignia through awards of share options.
 
    From inception of the 1996 Scheme in April 1996 to December 31, 1998,
options to subscribe for an aggregate of 348,625 shares were granted under the
1996 Scheme. None of these options were granted to executive officers,
directors, nominees for election as a director or associates of any of such
executive officers, directors or nominees.
 
SHARES SUBJECT TO THE 1996 SCHEME
 
    If any option granted pursuant to the 1996 Scheme expires or is surrendered
for any reason without being exercised in whole or in part, the shares released
from such option will again become available for grant under the 1996 Scheme or
the 1995 Plan. In addition, any shares issuable upon exercise of options granted
pursuant to previous Insignia employee option plans or the 1995 Plan that expire
or become unexercisable for any reason without having been exercised in full
also will become available for grant under the 1996 Scheme.
 
ELIGIBILITY
 
    Options may be granted under the 1996 Scheme to employees, including
officers and directors who are also employees, of Insignia, or any parent or
subsidiary of Insignia. Insignia generally grants options under the 1996 Scheme
to employees who are resident or are ordinarily resident outside of the United
States and who ordinarily perform all or part of the duties of their employment
outside of the United States. As of December 31, 1998, approximately 58 persons
were eligible to receive options under the 1996 Scheme, no shares had been
issued upon exercise of options and options to purchase 199,750 shares were
outstanding under the 1996 Scheme.
 
ADMINISTRATION
 
    The 1996 Scheme is administered by the Compensation Committee the members of
which are appointed by the Board. The Compensation Committee currently consists
of Albert E. Sisto and Vincent S. Pino, both of whom are "non-employee
directors" as that term is defined in Rule 16b-3 promulgated under the Exchange
Act and "outside directors" as that term is defined pursuant to Section 162(m)
of the Code.
 
                                       10
<PAGE>
    Subject to the terms of the 1996 Scheme, the Compensation Committee
determines the persons who are to receive options, the number of shares subject
to each such option and the terms and conditions of each such option. The
Compensation Committee has the authority to construe and interpret any of the
provisions of the 1996 Scheme or any options granted thereunder. Nicholas,
Viscount Bearsted, Insignia's Chairman, and Richard M. Noling, Insignia's
President and Chief Executive Officer, constitute a committee that is authorized
to make grants of options to non-officer employees pursuant to guidelines
established by the Board.
 
SHARE OPTIONS
 
    Options granted under the 1996 Scheme have a maximum term of ten years after
the date of grant. The exercise price of an option granted under the 1996 Scheme
may not be less than the higher of the market value (as defined in the 1996
Scheme) of an Ordinary Share on the trading day immediately preceding the date
of grant and its nominal value. The exercise price of options granted under the
1996 Scheme may be paid: (1) in cash (by check); or where permitted by law and
approved by the Committee (2) by waiver of compensation due to or accrued by the
optionee for services rendered; (3) by a "same-day sale" commitment from the
optionee and a broker-dealer that is a member of the National Association of
Securities Dealers (an "NASD Dealer"); (4) by a "margin" commitment from the
optionee and an NASD Dealer; or (5) by any combination of the foregoing.
 
MERGERS, CONSOLIDATIONS, CHANGE OF CONTROL
 
    In the event of a change of control of Insignia or the sale of substantially
all the assets of Insignia, the successor corporation may assume or substitute
equivalent options in exchange for those granted under the 1996 Scheme or
provide substantially similar consideration to optionees under the 1996 Scheme
as is offered to shareholders of Insignia. In the event that the successor
corporation, if any, does not assume or substitute the options or offer
substantially similar consideration, the options will expire on such transaction
at the time and upon the conditions as specified in the 1996 Scheme or as the
Compensation Committee determines.
 
AMENDMENT OF THE 1996 SCHEME
 
    The Board may at any time terminate or amend the 1996 Scheme, including
amendment of any form of option or instrument to be executed pursuant to the
1996 Scheme. However, the Board may not amend the 1996 Scheme in any manner that
requires shareholder approval pursuant to the Exchange Act or Rule 16b-3 (or its
successor) promulgated thereunder without such approval.
 
TERM OF THE 1996 SCHEME
 
    The 1996 Scheme will terminate in April 2006, ten years from the date the
1996 Scheme was adopted by Insignia in general meeting. Such termination will
not affect the options outstanding at that time.
 
UNITED KINGDOM INCOME TAX INFORMATION
 
    The following is a general summary as of the date of this proxy statement of
the United Kingdom income tax consequences for employees participating in the
1996 Scheme who are resident or are ordinarily resident in the United Kingdom
and who ordinarily perform all or part of the duties of their employment in the
United Kingdom. Because the tax laws may change and because income tax
consequences may vary depending upon the particular circumstances of each
participant, each participant should consult his or her own tax advisor
regarding the income tax consequences of participation in the 1996 scheme. The
following discussion does not purport to describe income tax consequences or tax
consequences for participants in countries other than the United Kingdom.
 
                                       11
<PAGE>
    A participant in the 1996 Scheme will be liable to be assessed to income tax
on the difference between the exercise price of the shares subject to such
participant's option and the market value of the shares at the date of exercise
of the option. If the option is granted on or after November 27, 1996 the income
tax due will be collected under the "pay as you earn system."
 
    If a participant exercises an option granted after April 5, 1999, the
participant will be required to pay employee national insurance contributions on
all or part of the gain received at the time of exercise if the participant's
earnings have not reached the maximum employee national insurance contributions'
threshold.
 
    Capital gains tax may be payable on the eventual disposal of the shares
which the optionee acquires upon exercise of an option. The liability to capital
gains tax will usually be based on the difference between the market value of
the shares at the date of exercise of the option and the price at which the
shares are sold. However, if the shares are given away or sold for less than
their market value to a "connected person" being a spouse or a relative of the
seller or the seller's spouse or the spouse of any such relative then, for the
purposes of assessing the capital gains tax liability, the seller will be deemed
to have disposed of the shares at their market value on the date of disposal.
 
ERISA
 
    The 1996 Scheme is not subject to any of the provisions of ERISA.
 
NEW PLAN BENEFITS
 
    The amounts of future option grants under the 1996 Scheme are not
determinable because, under the terms of the 1996 Scheme, such grants are made
in the discretion of the Compensation Committee. Future option exercise prices
are not determinable because they are based upon the fair market value of
Insignia's ADSs on the date of grant.

    The 1995 Plan was adopted by the Board in February 1995 and approved by the
shareholders in March 1995. The purpose of the 1995 Plan is to attract, retain
and provide equity incentives to selected persons to promote the financial
success of Insignia through awards of share options.
 
    From its inception in November 1995 to December 31, 1998, options to
purchase an aggregate of 2,917,400 shares were granted under the 1995 Plan. Of
these, options were granted to the Named Officers, as follows: Richard M.
Noling, President and Chief Executive Officer, 520,000 shares; Stephen M.
Ambler, Chief Financial Officer, Company Secretary and Senior Vice President,
108,750 shares; George Buchan, Senior Vice President of Engineering and UK
General Manager, 75,000 shares; Ronald C. Workman, Senior Vice President of
Marketing, 100,000 shares; David B. Winterburn, former Senior Vice President of
Business Development and Chief Technology Officer, 130,000 shares; and Joseph A.
Taglia, former Senior Vice President of Sales and Marketing, 110,000 shares.
During the same period, Insignia's current executive officers as a group (4
persons) had been granted options to purchase a total of 803,750 shares and the
current directors or nominees for election as a director who are not executive
officers as a group (3 persons) had been granted options to purchase a total of
105,000 shares. No options were granted during the period under the 1995 Plan to
any associate of any executive officer or director of Insignia, and no other
person received 5% or more of such options.
 
SHARES SUBJECT TO THE 1995 PLAN
 
    If any option granted pursuant to the 1995 Plan expires or terminates for
any reason without being exercised in whole or in part, the shares released from
such option will again become available for grant
 
                                       12
<PAGE>
under the 1995 Plan or the 1996 Scheme. In addition, any shares issuable upon
exercise of options granted pursuant to previous Insignia employee option plans
or the 1996 Scheme that expire or become unexercisable for any reason without
having been exercised in full also will become available for grant under the
1995 Plan.
 
ELIGIBILITY
 
    Options may be granted under the 1995 Plan to employees, officers,
directors, consultants and advisors of Insignia, or any parent, subsidiary or
affiliate of Insignia. The aggregate maximum number of shares that may be issued
to any one optionee under the 1995 Plan in any one year is 500,000 shares. As of
December 31, 1998, approximately 40 persons were eligible to receive options
under the 1995 Plan, 1,688 shares had been issued upon exercise of options and
1,619,777 shares were subject to outstanding options.
 
ADMINISTRATION
 
    The 1995 Plan is administered by the Compensation Committee. Subject to the
terms of the 1995 Plan, the Compensation Committee determines the persons who
are to receive options, the number of shares subject to each such option and the
terms and conditions of each such option. The Compensation Committee has the
authority to construe and interpret any of the provisions of the 1995 Plan or
any options granted thereunder. Nicholas, Viscount Bearsted, Insignia's Chairman
and Mr. Noling, Insignia's President and Chief Executive Officer, constitute a
committee that is authorized to make grants of options to non-officer employees
pursuant to guidelines established by the Board.
 
SHARE OPTIONS
 
    Options granted under the 1995 Plan may be incentive stock options ("ISOs")
within the meaning of Section 422 of the Code or nonqualified stock options
("NQSOs"). Only employees of Insignia, or of a parent or subsidiary of Insignia,
may be granted ISOs. Options under the 1995 Plan have a maximum term of 10 years
after the date of grant, except that the term of an option granted to a person
holding more than 10% of the total combined voting power of all classes of stock
of Insignia, or any parent or subsidiary of Insignia, is limited to five years.
 
    The exercise price of an option granted under the 1995 Plan may not be less
than the fair market value (as defined in the 1995 Plan) of an Ordinary Share on
the date of grant, except that the exercise price of an ISO granted to a person
holding more than 10% of the total combined voting power of all classes of stock
of Insignia, or any parent or subsidiary of Insignia, must be not less than 110%
of such fair market value.
 
    The exercise price of options granted under the 1995 Plan, plus any
applicable income tax withholding, may be paid: (1) in cash (by check); or where
permitted by law and approved by the Committee, in its sole discretion, at the
time of grant (2) by waiver of compensation due to or accrued by the optionee
for services rendered; (3) by a "same-day sale" commitment from the optionee and
an NASD Dealer; (4) by a "margin" commitment from the optionee and an NASD
Dealer; or (5) by any combination of the foregoing.
 
MERGERS, CONSOLIDATIONS, CHANGE OF CONTROL
 
    In the event of a merger, consolidation, dissolution or liquidation of
Insignia, the sale of substantially all the assets of Insignia or any other
similar corporate transaction, the successor corporation may assume, replace or
substitute equivalent options in exchange for those granted under the 1995 Plan
or provide substantially similar consideration, shares or other property subject
to repurchase restrictions no less favorable to optionees under the 1995 Plan.
In the event that the successor corporation, if any, does not assume or
substitute the options, the options will expire on such transaction at the time
and upon the conditions as the Committee determines.

AMENDMENT OF THE 1995 PLAN
 
    The Board may at any time terminate or amend the 1995 Plan, including
amendment of any form of option agreement, exercise agreement or instrument to
be executed pursuant to the 1995 Plan. However, the Board may not amend the 1995
Plan in any manner that requires shareholder approval pursuant to the Code or
the regulations promulgated thereunder, the Exchange Act or Rule 16b-3 (or its
successor) promulgated thereunder without such approval.
 
TERM OF THE 1995 PLAN
 
    The 1995 Plan will terminate in February 2005, ten years from the date the
1995 Plan was adopted by the Board.
 
UNITED STATES FEDERAL INCOME TAX INFORMATION
 
    The following is a general summary as of the date of this proxy statement of
the federal income tax consequences to Insignia and optionees associated with
options granted under the 1995 Plan. The federal tax laws may change and the
federal, state and local tax consequences for any optionee will depend upon his
or her individual circumstances. Each optionee is encouraged to seek the advice
of a qualified tax advisor regarding the tax consequences of participation in
the 1995 Plan.
 
    INCENTIVE STOCK OPTIONS.  The optionee will not recognize income upon grant
of an ISO and will not incur tax on its exercise (unless the optionee is subject
to the alternative minimum tax described below). If the optionee holds the stock
acquired upon exercise of an ISO (the "ISO Shares") for one year after the date
the option was exercised and for two years after the date the option was
granted, the optionee generally will realize long-term capital gain or loss
(rather than ordinary income or loss) upon disposition of the ISO Shares. This
gain or loss will be equal to the difference between the amount realized upon
such disposition and the amount paid for the ISO Shares.
 
    If the optionee disposes of ISO Shares prior to the expiration of either
required holding period (a "disqualifying disposition"), then the gain realized
upon such disposition, up to the difference between the fair market value of the
ISO Shares on the date of exercise (or, if less, the amount realized on a sale
of such shares) and the option exercise price, will be treated as ordinary
income. Any additional gain will be long-term or short-term capital gain,
depending upon the amount of time the ISO Shares were held by the optionee.
 
    ALTERNATIVE MINIMUM TAX.  The difference between the fair market value of
the ISO Shares on the date of exercise and the exercise price is an adjustment
to income for purposes of the alternative minimum tax (the "AMT"). The AMT
(imposed to the extent it exceeds the taxpayer's regular tax) is 26% of an
individual taxpayer's alternative minimum taxable income (28% in the case of
alternative minimum taxable income in excess of $175,000). Alternative minimum
taxable income is determined by adjusting regular taxable income for certain
items, increasing that income by certain tax preference items (including the
difference between the fair market value of the ISO Shares on the date of
exercise and the exercise price) and reducing this amount by the applicable
exemption amount ($45,000 in the case of a joint return, subject to reduction
under certain circumstances). If a disqualifying disposition of the ISO Shares
occurs in the same calendar year as exercise of the ISO, there is no AMT
adjustment with respect to those ISO Shares. Also, upon a sale of ISO Shares
that is not a disqualifying disposition, alternative minimum taxable income is
reduced in the year of sale by the excess of the fair market value of the ISO
Shares at exercise over the amount paid for the ISO Shares.
 
    NONQUALIFIED STOCK OPTIONS.  An optionee will not recognize any taxable
income at the time an NQSO is granted. However, upon exercise of an NQSO the
optionee will include in income as compensation an amount equal to the
difference between the fair market value of the shares on the date of exercise
and the optionee's exercise price. The included amount will be treated as
ordinary income by the optionee and may
 
                                       14
<PAGE>
be subject to income tax and FICA withholding by Insignia (either by payment in
cash or withholding out of the optionee's salary). Upon resale of the shares by
the optionee, any subsequent appreciation or depreciation in the value of the
shares will be treated as capital gain or loss.
 
    TAX TREATMENT OF INSIGNIA.  Insignia will be entitled to a deduction in
connection with the exercise of an NQSO by a domestic employee or director to
the extent that the optionee recognizes ordinary income. Insignia will be
entitled to a deduction in connection with the disposition of ISO Shares only to
the extent that the optionee recognizes ordinary income on a disqualifying
disposition of the ISO Shares.
 
ERISA
 
    The 1995 Plan is not subject to any of the provisions of ERISA.
 
NEW PLAN BENEFITS
 
    The amounts of future option grants under the 1995 Plan are not determinable
because, under the terms of the 1995 Plan, such grants are made in the
discretion of the Compensation Committee. Future option exercise prices are not
determinable because they are based upon the fair market value of Insignia's
ADSs on the date of grant.
 
              THE BOARD RECOMMENDS A VOTE FOR RESOLUTIONS 6 AND 7
 
                  PROPOSALS 8 AND 9:  ALLOTMENT OF SECURITIES
 
    Section 80 of the Act prohibits a company from allotting securities without
the authority of the shareholders of the company in general meeting. This is
supplemented by Section 89 of the Act, which requires (subject to specified
exceptions) that a company may not allot new securities unless it has first
offered them to existing shareholders.
 
    The directors are authorized to allot shares up to an aggregate nominal
value of L4,362,417 pursuant to an ordinary resolution passed by Insignia on
April 19, 1996 and expiring five years from that date, and to do so without
first offering the shares to existing shareholders.
 
    It is now proposed to cancel these authorities, to the extent that they have
not already been relied upon and, by the passing of Resolution 8 as an Ordinary
Resolution, to authorize the directors for a period of five years to allot
relevant securities having an aggregate nominal value of up to L2,930,913.20.
 
    Resolution 9, if passed as a Special Resolution, will authorize the
directors, for a period of five years, to allot equity securities under the
authority conferred by Resolution 8 without first offering them to the
shareholders.
 
    Insignia believes that it will require additional financing in 1999. To
date, Insignia has made no commitments nor agreed to any arrangements to obtain
additional financing, but is currently considering various financing
alternatives. The resolutions adopted by the shareholders in 1996 authorize the
Board to allot shares, but do not authorize other securities, such as
convertible promissory notes or warrants to purchase shares. Resolutions 8 and 9
authorize the Board to allot shares, as well as other types of securities and
options or warrants to purchase securities. The Board believes that this
authority will provide Insignia with the flexibility necessary to obtain
additional financing. There can be no assurance that Insignia will be able to
obtain additional financing when needed, on acceptable terms, or at all. The
failure to raise additional funds on a timely basis and on sufficiently
favourable terms could have a material adverse effect on the business, operating
results and financial condition of Insignia.
 
               THE BOARD RECOMMENDS A VOTE FOR PROPOSALS 8 AND 9

    The following table sets forth further information regarding individual
grants of rights to purchase ordinary shares during 1998 to each of the Named
Officers. In accordance with the rules of the Securities and Exchange Commission
(the "SEC"), the table sets forth the hypothetical gains or "option spreads"
that would exist for the options at the end of their respective ten-year terms.
These gains are based on assumed rates of annual compounded share price
appreciation of 5% and 10% from the dates the options were granted to the end of
the respective option terms. Actual gains, if any, on option exercises depend
upon the future performance of the ordinary shares and ADSs. There can be no
assurance that the potential realizable values shown in this table will be
achieved.

                             EMPLOYMENT AGREEMENTS
 
    Effective March 25, 1997, Mr. Noling entered into an employment agreement
with Insignia, which is terminable by either party upon six month's notice and
by Insignia for cause at any time. In connection with such agreement, Mr. Noling
was granted options to purchase (i) 100,000 ordinary shares at an exercise price
of $1.969, such options being 100% vested and immediately exercisable, (ii)
100,000 ordinary shares at an exercise price of $1.969, such options to vest and
become exercisable at the rate of 2.0833% of the shares on the first day of each
month following the date of grant and (iii) 200,000 ordinary shares on the day
of the 1997 Annual General Meeting, such options to vest and become exercisable
at the rate of 2.0833% of the shares on the first day of each month following
the date of grant. The Annual General Meeting was held on May 29, 1997 and the
options were granted at an exercise price of $2.375. 100,000 of these options
are subject to accelerated vesting and exercisability should Insignia meet
certain earnings per share ("EPS") targets as follows: (a) 25,000 options are
accelerated should the EPS exceed $0.07 for 2 consecutive quarters, (b) 37,500
options are accelerated should the EPS exceed $0.14 for 2 consecutive quarters
and (c) 37,500 options are accelerated should the EPS exceed $0.21 for 2
consecutive quarters, with a maximum of one early vesting event per quarter.
These 100,000 options fully vest upon a takeover or merger of Insignia.
 
    The employment agreement continues through May 31, 2001, and is
automatically extended for an additional year at the end of the term unless
either party gives notice six months prior to November 30, 2000 to terminate
effective upon the expiration of the then current term. In the event of any
business combination resulting in a change of control of Insignia or in the
event of disposal of a majority of the assets of Insignia, and the termination
or constructive termination of Mr. Noling's employment, Mr. Noling
 
                                       20
<PAGE>
shall receive his then current full salary for a period of twelve months
following such termination. In addition he shall be entitled to continued
vesting and exercisability of his options for a period of twelve months after
termination and shall be entitled to participate in Insignia's employee benefits
on the same basis as if he were an employee.
 
    In January 1993, Mr. Buchan entered into an employment agreement with
Insignia, which may be terminated by either party upon six months' notice and by
Insignia for cause at any time. In the event of any business combination, change
in control or disposal of a majority of the assets of Insignia, Mr. Buchan's
employment may be terminated with three months' notice, and upon such
termination Mr. Buchan will be entitled to a payment equivalent to his current
annual salary plus estimated bonus for the year following termination and all
his outstanding share options will become exercisable.
 
    In July 1998, the Company loaned Mr. Winterburn $70,000 to assist in the
purchase of a house. The loan is represented by a promissory note, and bears
interest at the prime rate. Provided Mr. Winterburn remains an employee of the
Company, the Company agreed to forgive 25% of unpaid principal on January 10,
1999 and 25% each January 10 thereafter up to and including January 10, 2002.
Mr. Winterburn's employment terminated in March 1999, and the remaining unpaid
principal and interest is repayable to the Company within 30 days.
 
          COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    The Compensation Committee of the Board makes all decisions involving the
compensation of executive officers of Insignia. The Compensation Committee
consists of Albert E. Sisto and Vincent S. Pino, both of whom are non-employee
directors. John R. Johnston served on the Compensation Committee until his
resignation as a director in July 1998. Mr. Pino was elected to the Compensation
Committee in October 1998. Paul L. Borrill served on the Compensation Committee
until he resigned in January 1999, at which time Mr. Sisto was elected to serve
on the committee.
 
    Insignia entered into a consulting agreement with Mr. Sisto, dated December
28, 1998, whereby Mr. Sisto will provide sales consulting, sales training,
advice and assistance as Insignia may from time to time request over a term of
six months. Mr. Sisto shall receive a fee of $500 for each half-day of service
provided, subject to a maximum of $35,000. Mr. Sisto shall also receive a bonus
fee for each qualifying Jeode customer contract signed in his assigned
geographic region. A qualifying customer contract is defined as a contract with
a value in excess of $500,000 over two years after signing by Insignia and the
customer. The agreement is terminable by either party upon ten days written
notice and by Insignia for any reason with written notice.
 
                      REPORT OF THE COMPENSATION COMMITTEE
 
    Final decisions regarding executive compensation and stock option grants to
executives are made by the Compensation Committee.
 
GENERAL COMPENSATION POLICY
 
    The Compensation Committee acts on behalf of the Board to establish the
general compensation policy of Insignia for all employees of Insignia. The
Compensation Committee typically reviews base salary levels and target bonuses
for the Chief Executive Officer ("CEO") and other executive officers and
employees of Insignia at or about the beginning of each fiscal year. The
Compensation Committee administers Insignia's incentive and equity plans,
including the 1995 Stock Option Plan for U.S. Employees, the U.K. Employee Share
Option Scheme 1996 and the 1995 Employee Share Purchase Plan.
 
    The Compensation Committee's philosophy in compensating executive officers,
including the CEO, is to relate compensation directly to corporate performance.
Thus, Insignia's compensation policy, which applies to executive officers and
other key employees of Insignia, relates a portion of each individual's total
 
                                       21
<PAGE>
compensation to the company objectives and individual objectives set forth at
the beginning of the year. Consistent with this policy, a designated portion of
the compensation of the executive officers of Insignia is contingent on
corporate performance and, in the case of executive officers, is also based on
the individual officer's performance as measured against personal objectives.
Long-term equity incentives for executive officers are effected through the
granting of share options. Options generally have value for the executive only
if the price of Insignia's shares increases above the fair market value on the
grant date and the executive remains in Insignia's employ for the period
required for the shares to vest.
 
    The base salaries, incentive compensation and option grants of the executive
officers are determined in part by the Compensation Committee's informal review
of data on prevailing compensation practices in technology companies with whom
Insignia competes for executive talent and by its evaluation of such information
in connection with Insignia's corporate goals. To this end, the Compensation
Committee attempted to compare the compensation of Insignia's executive officers
with the compensation practices of comparable companies to determine base
salary, target bonuses and target total cash compensation. In addition to their
base salaries, Insignia's executive officers, including the CEO, are each
eligible to receive a quarterly cash bonus and option grants.
 
    In preparing the performance graph for this proxy statement, Insignia used
the S&P Computer Software and Services Index as its published line of business
index. The compensation practices of most of the companies in such Index were
not reviewed by Insignia when the Compensation Committee reviewed the
compensation information described above because such companies were determined
not to be competitive with Insignia for executive talent.
 
1998 EXECUTIVE COMPENSATION
 
    BASE COMPENSATION.  The information described above was presented to the
Compensation Committee in January 1998. The Compensation Committee reviewed the
recommendations and performance and market data outlined above and established a
base salary level to be effective January 1, 1998 for each executive officer,
including the CEO.
 
    INCENTIVE COMPENSATION.  Cash bonuses are awarded to the extent that an
executive officer achieved predetermined individual objectives and Insignia met
predetermined objectives set by the Board at the beginning of the year. The
CEO's subjective judgment of executives' performance (other than his own) is
taken into account in determining whether those objectives have been satisfied.
 
    SHARE OPTIONS.  Share options typically have been granted to executive
officers when the executive first joins Insignia, in connection with a
significant change in responsibilities and, occasionally, to achieve equity
within a peer group. the Compensation Committee may, however, grant additional
options to executives for other reasons. The number of shares subject to each
option granted is within the discretion of the Compensation Committee and is
based on anticipated future contribution and ability to impact corporate and/or
business unit results, past performance or consistency within the executive's
peer group. In addition, in 1998, long-term incentives in the form of option
grants were considered appropriate because options generally have value only if
the price of Insignia's shares increases above the exercise price and the
optionee remains in the employ of Insignia for the time required for the options
to vest. The options generally become exercisable over a four-year period and
are granted at a price that is equal to the fair market value of the ADSs on the
date of grant. In 1998, the Compensation Committee considered these factors, as
well as the number of options held by such executive officers as of the date of
grant that remained unvested, and determined that additional grants should be
made in 1998.
 
    For 1999, the Compensation Committee will be considering whether to grant
future options to executive officers based on the factors described above, with
particular attention to Insignia-wide management objectives and the executive
officers' success in obtaining specific individual financial and operational
objectives established or to be established for 1999, to Insignia's expected
results and to the number of options currently held by the executive officers
that remain unvested.
 
                                       22
<PAGE>
    COMPANY PERFORMANCE AND CEO COMPENSATION.  For 1998, the Compensation
Committee recommended an increase of $15,000 in Mr. Noling's base salary. In
addition, the Compensation Committee granted options to purchase 20,000 shares
to Mr. Noling. Mr. Noling was responsible for Insignia meeting certain of its
objectives in 1998. After careful review of Insignia's performance as measured
against its objectives and the criteria set forth above under the discussion of
incentive compensation, the Compensation Committee recommended that bonuses in
the aggregate amount of $75,171 be paid to Mr. Noling.
 
    COMPLIANCE WITH SECTION 162(M) OF THE INTERNAL REVENUE CODE OF 1986.  For
1999, Insignia intends to comply with the requirements of Section 162(m) of the
Internal Revenue Code of 1986, as amended. The 1995 Plan is already in
compliance with Section 162(m) by limiting stock awards to named executive
officers. Insignia does not expect cash compensation for 1999 to be in excess of
$1,000,000 nor, therefore, affected by the requirements of Section 162(m).

    The share price performance graph below is required by the SEC and shall not
be deemed to be incorporated by reference by any general statement incorporating
by reference this Proxy Statement into any filing under the Securities Act of
1933, as amended, or under the Exchange Act, except to the extent that Insignia
specifically incorporates this information by reference, and shall not otherwise

    The graph below compares the cumulative total shareholder return on the ADSs
of Insignia from the effective date of Insignia's Registration Statement with
respect to Insignia's initial public offering (November 13, 1995) to March 31,
1999 with the cumulative total return on the Nasdaq Stock Market (U.S. and
Foreign) and the S&P Computer Software and Services Index (assuming the
investment of $100 in Insignia's ADSs on the date of Insignia's initial public
offering and in each of the indexes on October 31, 1995, and reinvestment of all
dividends).

                              CERTAIN TRANSACTIONS
 
    Since January 1, 1998, there has not been, nor is there currently proposed,
any transaction or series of transactions to which Insignia or any of its
subsidiaries was or is to be a party in which the amount involved exceeds
$60,000 and in which any executive officer, director or holder of more than 5%
of Insignia's ordinary shares had or will have a direct or indirect material
interest other than (i) normal compensation arrangements, which are described
under "Proposals 3 and 4--Election and Re-election of Directors-- Director
Compensation" and "Executive Compensation" above and (ii) the transactions
described under "Employment Agreements" above.
 
                             SHAREHOLDER PROPOSALS
 
    Proposals of shareholders intended to be presented at Insignia's 1999 Annual
General Meeting must be received by Insignia at its registered office no later
than             , 2000 to be included in Insignia's Proxy Statement and form of
proxy relating to the meeting. This is without prejudice to shareholders' rights
under the Act to propose resolutions that may properly be considered at that
meeting.
 
            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
    Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
Insignia's directors and officers, and persons who own more than 10% of
Insignia's ordinary shares to file initial reports of ownership and reports of
changes in ownership with the SEC. Such persons are required by SEC regulation
to furnish Insignia with copies of all Section 16(a) forms that they file. Based
solely on its review of the copies of such forms furnished to Insignia and
written representations from the executive officers and directors, Insignia
believes that all Section 16(a) filing requirements were met.

             DIRECTORS' REPORT FOR THE YEAR ENDED 31 DECEMBER 1998
 
    The directors of Insignia Solutions PLC present herewith their report and
the audited accounts of the company and of the Group for the year ended 31
December 1998 in accordance with the format prescribed by the UK Companies Act.
 
PRINCIPAL ACTIVITIES
 
    The principal activities of the company and group are the design,
engineering, development, licensing and maintenance of computer software
products which provide cross platform compatibility solutions.
 
REVIEW OF BUSINESS AND FUTURE DEVELOPMENTS
 
    During the year the group generated revenues from sales of its packaged
software products to end users and from software development and licensing
agreements with a number of international US-based concerns. In 1998 the group
shipped two principal product lines, Softwindows and NTRIGUE.
 
    Total turnover was down 64% on 1997 at $14,096,000 (1997: $38,869,000). As a
result of the disposal of the NTRIGUE product line during the year, sales of
Softwindows accounted for 92% of turnover. There was a declining demand for
Softwindows, primarily as a result of the declining market for Apple Macintosh
compatible computers and increased competition reducing both prices and margins.
A resultant operating loss was recorded of $13,511,000 (1997: loss $12,045,000).
 
    On 5 February 1998 the company completed the disposal of its NTRIGUE
technology to Citrix Systems Inc for $17,687,000,of which $8,750,000 was subject
to a holdback in escrow (see note 7). As part of the disposal, the company
transferred 45 employees to Citrix, of whom 43 were development engineers. Sales
of NTRIGUE were discontinued in May 1998.
 
    The income from the sale of the NTRIGUE technology was offset by cash
outflows from operations, and at 31 December 1998, the group had cash and cash
equivalent balances and short term investments of $16,334,000 (1997:
$14,461,000) of which $9,100,000 (1997: Nil) was held in escrow.
 
    In the light of adverse trading in its subsidiary Insignia Solutions Inc,
the Directors have considered it prudent to write down the carrying value of the
investments by $2,000,000 in the balance sheet of the company (see note 10).
 
    In January 1998 the company announced its intention to launch a new product
line. This product line, called Jeode, is based on the company's Embedded
Virtual Machine (EVM) technology. Jeode is the company's implementation of Sun
Microsystem Inc's Java technology developed specifically for embedded systems.
The Jeode platform is enabled by the company's EVM and is designed to enable
software developers to create reliable, efficient and predictable embedded
products. In November 1998, the company delivered Beta versions of the Jeode
platform. The product has been available for sale since 16 March 1999 and is
expected to be the principal product line in 1999 and for the foreseeable
future.
 
    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 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.

                  INSIGNIA SOLUTIONS PLC AND ITS SUBSIDIARIES
       DIRECTORS' REPORT FOR THE YEAR ENDED 31 DECEMBER 1998 (CONTINUED)
 
GOING CONCERN
 
    The company requires additional funding to meet its current plans. The
directors are currently in negotiations with certain parties which, when
completed, are anticipated to provide sufficient funds for the group to meet its
operating and capital requirement for at least the next twelve months. The
directors believe there are alternative sources of finance available should
these negotiations not be completed. Accordingly the financial statements have
been prepared on a going concern basis and the directors consider it would not
be appropriate to reflect the consequences of a failure to raise additional
funds on a timely basis and with sufficiently favourable terms in these
financial statements.
 
SHARE CAPITAL
 
    The company issued 491,000 Ordinary shares on the exercise of share options
and 128,103 Ordinary shares through its employee share purchase plan during the
year.
 
DIVIDENDS AND TRANSFERS TO RESERVES
 
    The directors are unable to recommend payment of a dividend in respect of
the year ended 31 December 1998 (1997: Nil). The profit for the year $
422,000 (1997: loss of $10,658,000) will be transferred to reserves.
 
DIRECTORS
 
    The directors of the company during the year and to the date of this report
were:

       DIRECTORS' REPORT FOR THE YEAR ENDED 31 DECEMBER 1998 (CONTINUED)
 
POLICY ON PAYMENT OF CREDITORS
 
    It is the group's policy to agree payment terms with its suppliers, along
with other terms and conditions, when it enters into binding purchase contracts
and to abide by the agreed payment terms provided the supplier has provided the
goods or services in accordance with the terms and conditions of the contract.
The company had 41 days purchases outstanding at 31 December 1998 based on the
average daily amount invoiced by suppliers during the year ended 31 December
1998.
 
YEAR 2000
 
    Many currently installed computer systems and software products are coded to
accept two digit entries in the date code field. These date code fields will
need to accept four digit entries to distinguish 21(st) century dates from
20(th) century dates. As a result computer systems and software used by many
companies may need to be upgraded to comply with such "Year 2000" requirements.
 
    SoftWindows 98, SoftWindows 95 versions 4.0 and 5.0 and Real PC are Year
2000 compliant. Earlier versions of SoftWindows and all versions of Soft PC, a
product the company no longer ships, are not Year 2000 compliant, but all such
versions are upgradable to Year 2000 compliant products. Furthermore the new
Jeode product under development is Year 2000 compliant. The company does not
however guarantee that the target platforms on which both the SoftWindows and
Jeode products may be used are compliant since these are third party products.
 
    The company has also carried out an assessment of its own internal systems
to assess their ability to deal with the date change from 1999 to 2000 and the
introduction of the Euro and believes they are all Year 2000 compliant. The
costs of any remedial work necessary are expensed as incurred. The group does
not expect the costs associated with ensuring year 2000 and Euro compliance to
have a material effect on its financial position.
 
STATEMENT OF DIRECTORS' RESPONSIBILITIES
 
    Company law requires the directors to prepare accounts for each financial
year which give a true and fair view of the state of affairs of the group and
the company and of the profit or loss of the group for that period. In preparing
those accounts, the directors are required to:
 
    - select suitable accounting policies and then apply them consistently;
 
    - make judgements and estimates that are reasonable and prudent;
 
    - state whether applicable accounting standards have been followed, subject
      to any material departures disclosed and explained in the accounts;
 
    - prepare the accounts on the going concern basis unless it is inappropriate
      to presume that the group and company will continue in business.
 
    The directors are responsible for keeping proper accounting records which
disclose with reasonable accuracy at any time the financial position of the
group and company and enable them to ensure that the financial statements comply
with the Companies Act 1985. They are also responsible for safeguarding the
assets of the group and company and hence for taking reasonable steps for the
prevention and detection of fraud and other irregularities.

AUDITORS' REPORT TO THE MEMBERS OF
INSIGNIA SOLUTIONS PLC AND ITS SUBSIDIARIES
 
    We have audited the accounts on pages F-8 to F-29 which have been prepared
under the historical cost convention and the accounting policies set out on
pages F-14 to F-16.
 
RESPECTIVE RESPONSIBILITIES OF DIRECTORS AND AUDITORS
 
    The directors are responsible for preparing the Annual Report, including as
described on page F-6 the financial statements. Our responsibilities, as
independent auditors, are established by statute, the Auditing Practices Board
and our profession's ethical guidance.
 
    We report to you our opinion as to whether the financial statements give a
true and fair view and are properly prepared in accordance with the Companies
Act. We also report to you if, in our opinion, the director's report is not
consistent with the financial statements, if the company has not kept proper
accounting records, if we have not received all the information and explanations
we require for our audit, or if information specified by law regarding
directors' remuneration and transactions is not disclosed.
 
    We read the other information contained in the Annual Report and consider
the implications for our report if we become aware of any apparent misstatements
or material inconsistencies with the financial statements.
 
BASIS OF AUDIT OPINION
 
    We conducted our audit in accordance with Auditing Standards issued by the
Auditing Practices Board. An audit includes examination on a test basis, of
evidence relevant to the amounts and disclosures in the financial statements. It
also includes an assessment of the significant estimates and judgements made by
the directors in the preparation of the financial statements, and of whether the
accounting policies are appropriate to the company's circumstances, consistently
applied and adequately disclosed.
 
    We planned and performed our audit so as to obtain all the information and
explanations which we considered necessary in order to provide us with
sufficient evidence to give reasonable assurance that the financial statements
are free from material misstatement, whether caused by fraud of other
irregularity or error. In forming our opinion we also evaluated the overall
adequacy of the presentation of information in the financial statements.
 
OPINION
 
    In our opinion the financial statements give a true and fair view of the
state of the affairs of the company and the group at 31 December 1998 and of the
profit and cash flows of the group for the year then ended and have been
properly prepared in accordance with the Companies Act 1985.

                    NOTES TO THE ACCOUNTS--31 DECEMBER 1998
 
1  PRINCIPAL ACCOUNTING POLICIES AND BASIS OF PREPARATION OF THE FINANCIAL
STATEMENT
 
    The accounts have been prepared in US dollars and in accordance with
applicable accounting standards in the United Kingdom. A summary of the
principal group accounting policies, which have been applied consistently, is
set out below.
 
    The company requires additional funding to meet its current plans. The
directors are currently in negotiations with certain parties which, when
completed, are anticipated to provide sufficient funds for the group to meet its
operating and capital requirement for at least the next twelve months. The
directors believe there are alternative sources of finance available should
these negotiations not be completed. Accordingly the financial statements have
been prepared on a going concern basis and the directors consider it would not
be appropriate to reflect the consequences of a failure to raise additional
funds on a timely basis and with sufficiently favourable terms in these
financial statements.
 
(1)  BASIS OF ACCOUNTING
 
    The accounts have been prepared under the historical cost convention.
 
(2)  BASIS OF CONSOLIDATION
 
    The consolidated accounts include the company and all its subsidiaries.
Intragroup sales and profits are eliminated on consolidation and all sales and
profit figures relate to external transactions only.
 
(3)  TURNOVER
 
    Turnover, which excludes value added tax and sales tax, represents sales of
packaged software, software development fees and licence royalties.
 
(4)  REVENUE RECOGNITION
 
    The company's licence revenues are derived from product licensing fees
relating to the sale of packaged software products and royalties from
distributors, original equipment manufacturers ("OEM's") and site licences. The
company's service revenues are derived from OEM's for customers funded
engineering and from annual maintenance contracts.
 
    Product licensing fees are recognised upon shipment if no significant vendor
obligations remain and if collection of the resulting receivable is deemed
probable. The company grants distributors and resellers certain rights of return
and price protection on unsold merchandise held by those distributors and
resellers. Accordingly, provisions for estimated future returns, exchanges and
credits for price protection are accrued upon product shipment.
 
    The company has limited control over the extent to which products sold to
distributors and resellers are sold through to end users. Accordingly, a portion
of the company's sales may from time to time result in increased inventory at
its distributors and resellers. The company provides sale returns provisions for
distributor and reseller inventories. These provisions are based on the
company's estimates of expected sell-through by distributors and resellers of
its products.
 
    The company provides a limited amount of free telephone technical support to
customers. These activities are generally considered to be insignificant
postcontract customer obligations. Estimated costs of these activities are
accrued at the time of product shipment. Revenues from annual maintenance
contracts are recognised rateably over the term of the contract.
 
                                      F-14

                  INSIGNIA SOLUTIONS PLC AND ITS SUBSIDIARIES
 
              NOTES TO THE ACCOUNTS--31 DECEMBER 1998 (CONTINUED)
 
1  PRINCIPAL ACCOUNTING POLICIES AND BASIS OF PREPARATION OF THE FINANCIAL
STATEMENT (CONTINUED)
    Revenues from OEM's for funded engineering are recognised on a percentage of
completion basis, which is computed using the input measure of labour cost.
Minimum guaranteed royalty revenues not subject to significant future
obligations are generally recognised on shipment of software. Royalty revenues
that are subject to significant future obligations are recognised when earned.
Royalty revenues that exceed the minimum guarantees are recognised when
reported.
 
    Payments from OEM's and maintenance contracts received in advance of revenue
recognition are recorded as deferred revenue.
 
(5)  RESEARCH AND DEVELOPMENT EXPENDITURE
 
    The company capitalises internal software development costs incurred after
technological feasibility has been demonstrated and commercial viability
expected. The company defines establishment of technological feasibility as the
completion of a working model. Such capitalised amounts are amortised commencing
with the introduction of that product at the greater of the straight-line basis
utilising 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.
 
(6)  FOREIGN CURRENCIES
 
    The directors have determined that the group's and company's functional
currency is the US dollar.
 
    Accordingly non-monetary assets and liabilities whose original values are in
currencies other than dollars are stated at their historic dollar value.
Monetary assets and liabilities expressed in other currencies are translated
into dollars at the rate of exchange ruling at the year end. Transactions in
other currencies are translated into dollars at the average rate for the month
in which the transaction occurred or at the forward contract or option rate
where such a hedging transaction has been undertaken. All foreign exchange
differences are taken to the profit and loss account in the year in which they
arise.
 
(7)  TANGIBLE FIXED ASSETS
 
    Tangible fixed assets are stated at their purchase price, together with any
incidental expenses of acquisition.
 
    Provision for depreciation is made so as to write off the cost of tangible
fixed assets on a straight line basis over the expected useful economic lives of
the assets concerned. The principal annual rates used for this purpose are:
 
<TABLE>
<S>                                 <C>
Leasehold improvements              shorter of estimated useful life or remaining lease term
Computers and other equipment       33%
Fixtures and fittings               25-33%
</TABLE>
 
(8)  STOCKS
 
    Stocks are stated at the lower of cost and net realisable value. Cost is
determined on a first in first out basis and includes transport and handling
costs. Provision is made where necessary for stocks which are slow moving,
obsolete or defective.

STATEMENT (CONTINUED)
(9)  DEFERRED TAXATION
 
    Deferred taxation is provided on the liability method in respect of timing
differences between profit as computed for taxation purposes and profit as
stated in the accounts to the extent that it is probable in the opinion of the
directors that a liability will become payable in the foreseeable future.
Deferred tax assets are only recognised to the extent that they are expected to
be recoverable.
 
(10)  OPERATING LEASES
 
    Rentals payable under operating leases are charged on a straight line basis
over the lease term in arriving at operating profit.
 
(11)  FINANCE LEASE AND HIRE PURCHASE AGREEMENTS
 
    Where fixed assets are financed by leasing agreements or hire purchase
contracts which transfer to the group substantially all the benefits and risks
of ownership, the assets are treated as if they had been purchased outright and
are included in tangible fixed assets. The capital element of these commitments
is shown as obligations under finance lease and hire purchase contracts.
 
    Finance lease rentals are treated as consisting of capital and interest
elements; the capital element is applied to reduce the outstanding obligations
and the interest element is charged against profit in proportion to the reducing
capital element outstanding. Assets held under finance leases are depreciated
over the shorter of the lease term or the useful economic life of equivalent
owned assets.
 
(12)  PENSION COSTS
 
    Pension costs in respect of the group's defined contribution scheme and
401(k) plans are accounted for in the period to which they relate.

7  DISPOSAL OF PART OF THE GROUP'S OPERATIONS
 
    On 5 February 1998 the company completed the disposal of its NTRIGUE
technology to Citrix Systems for $17.687 million. As part of the disposal, the
company transferred 45 employees to Citrix, of whom 43 were development
engineers.
 
    Under the terms of the disposal agreement $8.937 million was paid to the
company in cash on 5 February 1998, and the remainder is being held in an escrow
account 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, Citrix released $2.5 million to the company
in February 1999. In January 1999 the company received an indemnity claim from
Citrix--see note 22.

    As permitted by Section 230(1)(b) of the Companies Act 1985, Insignia
Solutions plc has not published its separate profit and loss account. The loss
arising is dealt with in the consolidated profit and loss account (1998: loss of
$12,749,000, 1997: loss of $15,217,000).
 
19  PENSION COSTS
 
    The group has a 401(k) plan covering all of its US employees and a defined
contribution pension plan covering all its UK employees. Under both these plans,
employees may contribute a percentage of their compensation and the group makes
certain matching contributions. Both the employees' and the groups'
contributions are fully vested and nonforfeitable at all times. The assets of
both these plans are held separately from those of the group in independently
managed and administered funds. The group's contributions to these plans
aggregated $182,000 in 1998 (1997: $315,000).

(3)  CAPITAL COMMITMENTS
 
    There are no material capital commitments.
 
21  CURRENCY OPTIONS
 
    The group enters into currency option contracts to hedge the short-term
impact of sterling fluctuations against the US dollar. The gains and losses on
these contracts are included in the profit and loss account when the related
operating revenues and expenses are recognised. At 31 December 1998, there were
no currency options outstanding (1997: $2.0 million outstanding).
 
22  SIGNIFICANT POST BALANCE SHEET EVENTS
 
    On 29 January 1999, the company received an indemnity claim on the escrow
account of an uncertain amount, but estimated by the claimant, Citrix, not to
exceed $6.25 million. Subsequently $2.5 million was released in February 1999 as
due.
 
    Citrix' indemnity claim is based on a declaratory relief action that Citrix
filed against GraphOn Corp. in November 1998 in the United States District
Court, Southern District of Florida. Citrix' action against GraphOn seeks a
declaratory judgement that Citrix does not infringe any GraphOn proprietary
rights and

              NOTES TO THE ACCOUNTS--31 DECEMBER 1998 (CONTINUED)
 
22  SIGNIFICANT POST BALANCE SHEET EVENTS (CONTINUED)
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 unsubstantiated assertions first made by GraphOn, and disclosed to
Citrix in January 1998, that Insignia used GraphOn confidential information to
develop Insignia products, possibly including products Insignia sold to Citrix
in February 1998. GraphOn has never filed any action against either Insignia or
Citrix relating to its assertions and Insignia believes such assertions by
GraphOn are without merit or basis. Accordingly, Insignia intends to contest
Citrix' indemnity claim and the directors do not consider it necessary to
provide for any irrecoverability for amounts held in escrow.
 
23  RELATED PARTY TRANSACTIONS
 
    The company has taken advantage of the exemption in Financial Reporting
Standard No. 8 not to disclose transactions and balances between group entities
that have been eliminated on consolidation.
 
    Viscount Bearsted, a director of the company, holds a consultancy contract
with the company which causes him to be treated as a related party for the
amounts received under this contract. The amount payable in the year was $52,000
(1997--$39,000) and the balances due to him at the beginning and the end of the
year were $13,000.
 
    Other transactions involving directors are disclosed in notes 4 and 16 to
the accounts and in the Directors' Report on pages F-2 to F-6.
 
24  EARNINGS PER SHARE
 
    Basic earnings per share is calculated by dividing the earnings attributable
to ordinary shareholders by the weighted average number of ordinary shares in
issue during the year.
 
    For diluted earnings per share, the weighted average number of ordinary
shares in issue is adjusted to assume conversion of all dilutive potential
ordinary shares: those share options granted to employees where the exercise
price is less than the average market price of the company's ordinary shares
during the year.

                        1995 EMPLOYEE SHARE PURCHASE PLAN

              Adopted by the Board of Directors on February 9, 1995
               and Amended on December 15, 1995 and April 20, 1999

1.   ESTABLISHMENT OF PLAN

          Insignia Solutions plc (the "COMPANY") proposes to grant options to 
subscribe for the Company's ordinary shares of 20p each, or any instruments 
evidencing such ordinary shares (e.g., American Depositary Shares or American 
Depositary Receipts), to eligible employees of the Company and its 
Subsidiaries (as hereinafter defined) pursuant to this Insignia Solutions plc 
1995 Employee Share Purchase Plan (this "PLAN"). For purposes of this Plan, 
"Parent Corporation" and "Subsidiary" (collectively, "SUBSIDIARIES") shall 
have the same meanings as "parent corporation" and "subsidiary corporation" 
in Sections 424(e) and 424(f), respectively, of the Internal Revenue Code of 
1986, as amended (the "CODE"). The Company intends the Plan to qualify as an 
"employee stock purchase plan" under Section 423 of the Code (including any 
amendments to or replacements of such section), and the Plan shall be so 
construed. Any term not expressly defined in the Plan but defined for 
purposes of Section 423 of the Code shall have the same definition herein. A 
total of nine hundred thousand (900,000) of the Company's ordinary shares is 
reserved for issue under the Plan. Such number shall be subject to 
adjustments effected in accordance with Section 14 of the Plan.

2.   PURPOSES

          The purpose of the Plan is to provide employees of the Company and 
Subsidiaries designated by the Board of Directors of the Company (the 
"BOARD") as eligible to participate in the Plan with a convenient means of 
acquiring an equity interest in the Company through payroll deductions, to 
enhance such employees' sense of participation in the affairs of the Company 
and Subsidiaries, and to provide an incentive for continued employment.

3.   ADMINISTRATION

          This Plan may be administered by the Board or a committee appointed 
by the Board (the "COMMITTEE"). If, at the time the Company becomes subject 
to Section 16 of the Securities Exchange Act of 1934, as amended (the 
"EXCHANGE ACT"), a majority of the Board is not comprised of Disinterested 
Persons as defined in Rule 16b-3(d) promulgated under the Exchange Act, the 
Board shall appoint a committee consisting of at least two (2) members of the 
Board, each of whom is a Disinterested Person. As used in this Plan, 
references to the "Committee" shall mean either such committee or the Board 
if no committee has been established. After registration of the Company under 
the Exchange Act, Board members who are not Disinterested Persons may

                                               1995 Employee Share Purchase Plan
                                                    as Amended on April 20, 1999


not vote on any matters affecting the administration of this Plan, but any 
such member may be counted for determining the existence of a quorum at any 
meeting of the Board. Subject to the provisions of the Plan and the 
limitations of Section 423 of the Code or any successor provision in the 
Code, all questions of interpretation or application of the Plan shall be 
determined by the Board and its decisions shall be final and binding upon all 
participants. Members of the Board shall receive no compensation for their 
services in connection with the administration of the Plan, other than 
standard fees as established from time to time by the Board for services 
rendered by Board members serving on Board committees. All expenses incurred 
in connection with the administration of the Plan shall be paid by the 
Company.

4.   ELIGIBILITY

          Any employee of the Company or the Subsidiaries is eligible to 
participate in an Offering Period (as hereinafter defined) under the Plan 
except the following:

               (a)  employees who are not employed by the Company or 
Subsidiaries on the fifteenth (15th) day of the month before the beginning of 
such Offering Period;

               (b) employees who are customarily employed for less than 20 
hours per week;

               (c) employees who are customarily employed for less than 5 
months in a calendar year;

               (d) employees who, together with any other person whose stock 
or shares would be attributed to such employee pursuant to Section 424(d) of 
the Code, own stock or shares or hold options to subscribe for ordinary 
shares or who, as a result of being granted an option under the Plan with 
respect to such Offering Period, would own shares or hold options to 
subscribe for shares possessing 5 percent or more of the total combined 
voting power or value of all classes of stock or shares of the Company or any 
of its Subsidiaries.

5.   OFFERING DATES

          The Offering Periods of the Plan (the "OFFERING PERIOD") shall be 
of six (6) months duration commencing February 1 and August 1 of each year 
and ending on July 31 and January 31 respectively. Notwithstanding the 
foregoing, the first Offering Period shall commence on the date of the 
initial public offering and shall end on the earlier of the first July 31 or 
January 31 thereafter (the "FIRST OFFERING PERIOD"). Payroll deductions of 
each participant are accumulated under the Plan during the Offering Periods. 
The first day of each Offering Period is referred to as the "Offering Date". 
The last business day of each Offering Period is referred to as the "Purchase 
Date". The Board shall have the power to change the duration of Offering 
Periods with respect to future offerings without shareholder approval if such 
change is announced at least fifteen (15) days prior to the scheduled 
beginning of the first Offering Period to be affected.

                                               1995 Employee Share Purchase Plan
                                                    as Amended on April 20, 1999


6.   PARTICIPATION IN THE PLAN

          Eligible employees may become participants in an Offering Period 
under the Plan on the first Offering Date after satisfying the eligibility 
requirements by delivering a subscription agreement to the Company's or 
Subsidiary's (whichever employs such employee) payroll department (the 
"PAYROLL DEPARTMENT") not later than five (5) days prior to such Offering 
Date unless a later time for filing the subscription agreement authorizing 
payroll deductions is set by the Board for all eligible employees with 
respect to a given Offering Period. An eligible employee who does not deliver 
a subscription agreement to the Payroll Department by such date after 
becoming eligible to participate in such Offering Period shall not 
participate in that Offering Period or any subsequent Offering Period unless 
such employee enrolls in the Plan by filing a subscription agreement with the 
Payroll Department not later than five (5) days prior to such subsequent 
Offering Date. Once an employee becomes a participant in an Offering Period, 
such employee will automatically participate in the Offering Period 
commencing immediately following the last day of the prior Offering Period 
unless the employee withdraws from the Plan or terminates further 
participation in the Offering Period as set forth in Section 11 below. Such 
participant is not required to file any additional subscription agreement in 
order to continue participation in the Plan.

7.   GRANT OF OPTION ON ENROLLMENT

          Enrollment by an eligible employee in the Plan with respect to an 
Offering Period will constitute the grant (as of the Offering Date) by the 
Company to such employee of an option to subscribe on the Purchase Date for 
up to that number of ordinary shares of the Company determined by dividing 
the amount accumulated in such employee's payroll deduction account during 
such Offering Period, and if applicable, as converted into U.S. Dollars at 
the Conversion Rate (as defined in Section 9(g)) on the Purchase Date, by the 
lower of (i) eighty-five percent (85%) of the fair market value of an 
ordinary share of the Company on the Offering Date (the "ENTRY PRICE") or 
(ii) eighty-five percent (85%) of the fair market value of an ordinary share 
of the Company on the Purchase Date; provided, however, that the number of 
ordinary shares of the Company subject to any option granted pursuant to this 
Plan shall not exceed the lesser of (a) the maximum number of shares set by 
the Board pursuant to Section 10(c) below with respect to the applicable 
Offering Period, or (b) 200% of the number of shares determined by using 85% 
of the fair market value of an ordinary share of the Company on the Offering 
Date as the denominator. Fair market value of an ordinary share of the 
Company shall be determined as provided in Section 8 hereof.

8.   PURCHASE PRICE

          The purchase price of shares issued pursuant to this Plan shall be 
payable in U.S. Dollars. The purchase price per share at which a share will 
be issued in any Offering Period shall be 85 percent of the lesser of:

          (a)  The fair market value on the Offering Date; or


                                       3
<PAGE>

                                                          Insignia Solutions plc
                                               1995 Employee Share Purchase Plan
                                                    as Amended on April 20, 1999

          (b) The fair market value on the Purchase Date.

Notwithstanding the foregoing, the purchase price per ordinary share shall not
in any circumstances be less than the U.S. Dollar equivalent, at the Conversion
Rate (as defined in Section 9(g)) on the Purchase Date, of 20p (being the par
value of an ordinary share).

          For purposes of the Plan, the term "fair market value" on a given 
date shall mean the fair market value of an ordinary share of the Company, or 
instrument evidencing such ordinary shares (e.g., American Depositary Shares 
or American Depositary Receipts) in U.S. Dollars, as determined by the 
Committee from time to time in good faith. If a public market exists for the 
shares, or instrument evidencing such ordinary shares (e.g., American 
Depositary Shares or American Depositary Receipts), the fair market value 
shall be the average of the last reported bid and asked prices for an 
ordinary share of the Company on the last trading day prior to the date of 
determination, or, in the event ordinary shares of the Company, or 
instruments evidencing such ordinary shares (e.g., American Depositary Shares 
or American Depositary Receipts), are listed on the Nasdaq National Market, 
the fair market value shall be the closing price of a share, or instrument 
evidencing such ordinary shares (e.g., American Depositary Shares or American 
Depositary Receipts), on the determination date as quoted on the Nasdaq 
National Market or if no such reported sale takes place on such date, the 
closing price on the next preceding trading date on which a reported sale 
occurred. Notwithstanding the foregoing, the fair market value of a share, or 
instrument evidencing such ordinary shares (e.g., American Depositary Shares 
or American Depositary Receipts), on the First Offering Date (which is the 
first business day of the First Offering Period under this Plan) shall be the 
price per share at which such shares or instruments are initially offered for 
sale to the public in the Company's initial public offering.

9.   PAYMENT OF PURCHASE PRICE; CHANGES IN PAYROLL
     DEDUCTIONS; ISSUE OF SHARES

          (a) The purchase price of the shares is accumulated by regular 
payroll deductions made during each Offering Period. The deductions are made 
as a percentage of the participant's compensation in one percent increments 
not less than 2 percent nor greater than 10 percent, not to exceed $25,000 
per year, or the U.S. Dollar equivalent determined at the Conversion Rate (as 
defined in Section 9(g)) on the Offering Date, or such lower limit set by the 
Committee. Compensation for U.S. employees shall mean all W-2 compensation, 
including, but not limited to base salary, wages, commissions, overtime, 
shift premiums and bonuses, plus draws against commissions and excluding car 
allowances and any other in kind employment related benefits; provided, 
however, that for purposes of determining a participant's compensation, any 
election by such participant to reduce his or her regular cash remuneration 
under Sections 125 or 401(k) of the Code shall be treated as if the 
participant did not make such election. Compensation for U.K. employees shall 
mean all compensation, including, but not limited to base salary, wages, 
commissions, overtime, the substantial equivalent of U.S. "shift premiums" 
and bonuses, plus draws against commissions and excluding car allowances and 
any other in kind employment related benefits. Payroll deductions shall 
commence on the first payday following the Offering Date and shall continue 
to the end of the Offering Period unless sooner altered or terminated as 
provided in the Plan.

                                               1995 Employee Share Purchase Plan
                                                    as Amended on April 20, 1999


          (b) A participant may lower (but not increase) the rate of payroll 
deductions during an Offering Period by filing with the Payroll Department a 
new authorization for payroll deductions, in which case the new rate shall 
become effective for the next payroll period commencing more than 15 days 
after the Payroll Department's receipt of the authorization and shall 
continue for the remainder of the Offering Period unless changed as described 
below. Such change in the rate of payroll deductions may be made at any time 
during an Offering Period, but not more than one change may be made effective 
during any Offering Period. A participant may increase or decrease the rate 
of payroll deductions for any subsequent Offering Period by filing with the 
Payroll Department a new authorization for payroll deductions not later than 
five (5) days prior to the beginning of such subsequent Offering Period.

          (c) All payroll deductions made for a participant are credited to 
his or her account under the Plan and are deposited with the general funds of 
the Company. No interest accrues on the payroll deductions. All payroll 
deductions received or held by the Company may be used by the Company for any 
corporate purpose, and the Company shall not be obligated to segregate such 
payroll deductions.

          (d) On each Purchase Date, so long as the Plan remains in effect 
and provided that the participant has not submitted a signed and completed 
withdrawal form before that date, as set forth in Section 11 below, which 
notifies the Company that the participant wishes to withdraw from that 
Offering Period under the Plan and have all payroll deductions accumulated in 
the account maintained on behalf of the participant as of that date returned 
to the participant, the Company shall apply the funds, and if applicable, as 
converted into U.S. Dollars at the Conversion Rate (as defined in Section 
9(g)) on the Purchase Date, then in the participant's account to the 
subscription for a whole number of ordinary shares reserved under the option 
granted to such participant with respect to the Offering Period to the extent 
that such option is exercisable on the Purchase Date. The purchase price per 
share shall be as specified in Section 8 of the Plan. Any cash remaining in a 
participant's account after such subscription for ordinary shares shall be 
refunded to such participant in cash, without interest; provided, however, 
that any amount remaining in such participant's account on a Purchase Date 
which is less than the amount necessary to subscribe for a single ordinary 
share shall be carried forward, without interest, into the next Offering 
Period. In the event that the Plan has been oversubscribed, all funds not 
used to subscribe for ordinary shares on the Purchase Date shall be returned 
to the participant, without interest. No ordinary shares shall be subscribed 
for on a Purchase Date on behalf of any employee whose participation in the 
Plan has terminated prior to such Purchase Date.

          (e) As promptly as practicable after the Purchase Date, the Company 
shall arrange the delivery to each participant of a certificate representing 
the shares issued upon exercise of his option.

          (f) During a participant's lifetime, such participant's option to 
subscribe for shares hereunder is exercisable only by him or her. The 
participant will have no interest or voting right in shares covered by his or 
her option until such option has been exercised. Shares to be delivered

                                                    as Amended on April 20, 1999


to a participant under the Plan will be registered in the name of the 
participant or in the name of the participant and his or her spouse.

          (g) "Conversion Rate" means the average currency conversion rate 
quoted by the Bank of America in London for converting Pounds Sterling into 
U.S. Dollars.

10.  LIMITATIONS ON SHARES TO BE PURCHASED

          (a) No employee shall be entitled to subscribe for shares under the 
Plan at a rate which, when aggregated with his or her rights to subscribe for 
shares under all other employee stock purchase plans of the Company or any 
Subsidiary, exceeds $25,000 (or if applicable, the U.S. Dollars equivalent 
determined at the Conversion Rate (as defined in Section 9(g)) as of the 
Offering Date) in fair market value, determined as of the Offering Date (or 
such other limit as may be imposed by the Code) for each calendar year in 
which the employee participates in the Plan.

          (b) No more than 200% of the number of shares determined by using 
85% of the fair market value of an ordinary share of the Company on the 
Offering Date as the denominator may be subscribed for by a participant on 
any single Purchase Date.

          (c) No employee shall be entitled to subscribe for more than the 
Maximum Share Amount (as defined below) on any single Purchase Date. Not less 
than thirty days prior to the commencement of any Offering Period, the Board 
may, in its sole discretion, set a maximum number of shares which may be 
subscribed for by any employee at any single Purchase Date (hereinafter the 
"MAXIMUM SHARE AMOUNT"). In no event shall the Maximum Share Amount exceed 
the amounts permitted under Section 10(b) above. If a new Maximum Share 
Amount is set, then all participants must be notified of such Maximum Share 
Amount not less than fifteen days prior to the commencement of the next 
Offering Period. Once the Maximum Share Amount is set, it shall continue to 
apply with respect to all succeeding Purchase Dates and Offering Periods 
unless revised by the Board as set forth above.

          (d) If the number of shares to be subscribed for on a Purchase Date 
by all employees participating in the Plan exceeds the number of shares then 
available for issue under the Plan, the Company will make a pro rata 
allocation of the remaining shares in as uniform a manner as shall be 
practicable and as the Board shall determine to be equitable. In such event, 
the Company shall give written notice of such reduction of the number of 
shares to be subscribed for under a participant's option to each participant 
affected thereby.

          (e) Any payroll deductions accumulated in a participant's account 
which are not used to subscribe for ordinary shares due to the limitations in 
this Section 10 shall be returned to the participant as soon as practicable 
after the end of the Offering Period, without interest.

                                                    as Amended on April 20, 1999


11.  WITHDRAWAL

          (a) Each participant may withdraw from an Offering Period under the 
Plan by signing and delivering to the Payroll Department notice on a form 
provided for such purpose. Such withdrawal may be elected at any time at 
least 15 days prior to the end of an Offering Period.

          (b) Upon withdrawal from the Plan, the accumulated payroll 
deductions shall be returned to the withdrawn participant, without interest, 
and his or her interest in the Plan shall terminate. In the event a 
participant voluntarily elects to withdraw from the Plan, he or she may not 
resume his or her participation in the Plan during the same Offering Period, 
but he or she may participate in any Offering Period under the Plan which 
commences on a date subsequent to such withdrawal by filing a new 
authorization for payroll deductions in the same manner as set forth in 
Section 6 above for initial participation in the Plan.

12.  TERMINATION OF EMPLOYMENT

       Termination of a participant's employment for any reason, including
retirement, death or the failure of a participant to remain an eligible
employee, immediately terminates his or her participation in the Plan. In such
event, the payroll deductions credited to the participant's account will be
returned to him or her or, in the case of his or her death, to his or her legal
representative, without interest. For purposes of this Section 12, an employee
will not be deemed to have terminated employment or failed to remain in the
continuous employ of the Company in the case of sick leave, military leave, or
any other leave of absence approved by the Board; provided that such leave is
for a period of not more than ninety (90) days or reemployment upon the
expiration of such leave is guaranteed by contract or statute.

13.  RETURN OF PAYROLL DEDUCTIONS

       In the event a participant's interest in the Plan is terminated by
withdrawal, termination of employment or otherwise, or in the event the Plan is
terminated by the Board, the Company shall promptly deliver to the participant
all payroll deductions credited to his account. No interest shall accrue on the
payroll deductions of a participant in the Plan.

14.  CAPITAL CHANGES

       Subject to any required action by the shareholders of the Company, the
number of ordinary shares covered by each option under the Plan which has not
yet been exercised and the number of ordinary shares which have been authorized
for issue under the Plan but have not yet been placed under option
(collectively, the "RESERVES"), as well as the price per ordinary share covered
by each option under the Plan which has not yet been exercised, shall be
proportionately adjusted for any increase or decrease in the number of issued
ordinary shares resulting from any consolidation or subdivision of ordinary
shares of the Company, or any bonus or other capitalization issue of ordinary
shares or any other increase or decrease in the number of issued ordinary shares
effected without receipt of consideration by the Company; provided, however,
that conversion of any

                                                    as Amended on April 20, 1999


convertible securities of the Company shall not be deemed to have been 
"effected without receipt of consideration." Such adjustment shall be made by 
the Board, whose determination shall be final, binding and conclusive. Except 
as expressly provided herein, no issue by the Company of shares of any class, 
or securities convertible into shares of any class, shall affect, and no 
adjustment by reason thereof shall be made with respect to, the number or 
price of ordinary shares subject to an option.

       In the event of the proposed dissolution or liquidation of the Company,
the Offering Period will terminate immediately prior to the consummation of such
proposed action, unless otherwise provided by the Board. The Board may, in the
exercise of its sole discretion in such instances, declare that the options
under the Plan shall terminate as of a date fixed by the Board and give each
participant the right to exercise his or her option as to all of the ordinary
shares comprised in the option, including shares in respect of which the option
would not otherwise be exercisable. In the event of a proposed sale of all or
substantially all of the assets of the Company, or the sale of the entire share
capital of the Company to another corporation, (whether for consideration in
cash or in the form of securities of any kind) (a "merger"), each option under
the Plan shall be assumed or an equivalent option shall be substituted by the
purchasing corporation or a parent or subsidiary of such purchasing corporation,
unless the Board determines, in the exercise of its sole discretion and in lieu
of such assumption or substitution, that the participant shall have the right to
exercise the option as to all of the ordinary shares comprised in the option. If
the Board makes an option exercisable in lieu of assumption or substitution in
the event of a merger or sale of assets, the Board shall notify the participant
that the option shall be fully exercisable for a period of twenty (20) days from
the date of such notice, and the option will terminate upon the expiration of
such period.

       The Board may, if it so determines in the exercise of its sole
discretion, also make provision for adjusting the Reserves, as well as the price
per ordinary share comprised in each outstanding option, in the event that the
Company effects one or more reorganizations, recapitalizations, rights offerings
or other increases or reductions of share capital, or in the event of a merger.

15.  NONASSIGNABILITY

       Neither payroll deductions credited to a participant's account nor any
rights with regard to the exercise of an option or to receive shares under the
Plan may be assigned, transferred, pledged or otherwise disposed of in any way
(other than by will, the laws of descent and distribution or as provided in
Section 22 hereof) by the participant. Any such attempt at assignment, transfer,
pledge or other disposition shall be without effect.

16.  REPORTS

       Individual accounts will be maintained for each participant in the Plan.
Each participant shall receive promptly after the end of each Offering Period a
report of his or her account setting forth the total payroll deductions
accumulated (and if applicable, the Conversion Rate (as defined in Section 9(g))
at which such participant's payroll deductions were converted into U.S.
Dollars), the number of shares subscribed for, the per share price thereof and
the remaining cash balance, if any, carried forward to the next Offering Period.

17.  NOTICE OF DISPOSITION

       Each participant shall notify the Company if the participant disposes of
any of the shares subscribed for in any Offering Period pursuant to this Plan if
such disposition occurs within two years from the Offering Date or within one
year from the Purchase Date on which such shares were subscribed for (the
"NOTICE PERIOD"). Unless such participant is disposing of any of such shares
during the Notice Period, such participant shall keep the certificates
representing such shares in his or her name (and not in the name of a nominee)
during the Notice Period. The Company may, at any time during the Notice Period,
place a legend or legends on any certificate representing shares acquired
pursuant to the Plan requesting the Company's transfer agent to notify the
Company of any transfer of the shares. The obligation of the participant to
provide such notice shall continue notwithstanding the placement of any such
legend on the certificates.

18.  NO RIGHTS TO CONTINUED EMPLOYMENT

          (a) Neither this Plan nor the grant of any option hereunder shall 
confer any right on any employee to remain in the employ of the Company or 
any Subsidiary, or restrict the right of the Company or any Subsidiary to 
terminate such employee's employment.

          (b) In the event that any person holding an option under the Plan 
ceases to be employed by the Company or a Subsidiary for whatever reason, he 
shall have no right to any compensation in respect of the loss of his right 
to receive shares under this Plan.

19.  EQUAL RIGHTS AND PRIVILEGES

       All eligible employees shall have equal rights and privileges with
respect to the Plan so that the Plan qualifies as an "employee stock purchase
plan" within the meaning of Section 423 or any successor provision of the Code
and the related regulations. Any provision of the Plan which is inconsistent
with Section 423 or any successor provision of the Code shall, without further
act or amendment by the Company or the Board, be reformed to comply with the
requirements of Section 423. This Section 19 shall take precedence over all
other provisions in the Plan.

20.  NOTICES

       All notices or other communications by a participant to the Company under
or in connection with the Plan shall be deemed to have been duly given when
received in the form specified by the Company at the location, or by the person,
designated by the Company for the receipt thereof.

21.  TERM; SHAREHOLDER APPROVAL

       This Plan shall become effective at such date and time as the
Registration Statement filed with the Securities and Exchange Commission
relating to the Company's securities is declared effective (and then only
provided that the initial public offering later closes). This Plan shall be
approved by the shareholders of the Company, in any manner permitted by
applicable corporate law, within twelve months before or after the date this
Plan is adopted by the Board. No subscription for shares pursuant to the Plan
shall occur prior to such shareholder approval. Thereafter, no later than twelve
(12) months after the Company becomes subject to Section 16(b) of the Exchange
Act, the Company will comply with the requirements of Rule 16b-3 with respect to
shareholder approval. The Plan shall continue until the earlier to occur of
termination by the Board, issue of all of the ordinary shares reserved for issue
under the Plan, or ten (10) years from the adoption of the Plan by the Board.

22.  DESIGNATION OF BENEFICIARY

          (a) A participant may file a written designation of a beneficiary 
who is to receive any shares and cash, if any, from the participant's account 
under the Plan in the event of such participant's death subsequent to the end 
of an Offering Period but prior to delivery to him of such shares and cash. 
In addition, a participant may file a written designation of a beneficiary 
who is to receive any cash from the participant's account under the Plan in 
the event of such participant's death prior to a Purchase Date.

          (b) Such designation of beneficiary may be changed by the 
participant at any time by written notice. In the event of the death of a 
participant and in the absence of a beneficiary validly designated under the 
Plan who is living at the time of such participant's death, the Company shall 
deliver such shares or cash to the executor or administrator of the estate of 
the participant, or if no such executor or administrator has been appointed 
(to the knowledge of the Company), the Company, in its discretion, may 
deliver such shares or cash to the spouse or to any one or more dependents or 
relatives of the participant, or if no spouse, dependent or relative is known 
to the Company, then to such other person as the Company may designate.

23.   CONDITIONS UPON ISSUE OF SHARES; LIMITATION ON SALE OF SHARES

       Shares shall not be issued with respect to an option unless the exercise
of such option and the issue and delivery of such shares pursuant thereto shall
comply with all applicable provisions of law, domestic or foreign, including,
without limitation, the Securities Act of 1933, as amended,

the Exchange Act, the rules and regulations promulgated thereunder, and the 
requirements of any stock exchange upon which the shares may then be listed, 
and shall be further subject to the approval of counsel for the Company with 
respect to such compliance.

24.    AMENDMENT OR TERMINATION OF THE PLAN

       The Board may at any time amend, terminate or extend the term of the
Plan, except that any such termination cannot affect options previously granted
under the Plan, nor may any amendment make any change in an option previously
granted which would adversely affect the right of any participant, nor may any
amendment be made without approval of the shareholders of the Company obtained
in accordance with Section 21 hereof within 12 months of the adoption of such
amendment (or earlier if required by Section 21) if such amendment would:

          (a)  increase the number of shares that may be issued under the Plan;

          (b) change the designation of the employees (or class of employees)
eligible for participation in the Plan; or

          (c) constitute an amendment for which shareholder approval is 
required in order to comply with Rule 16b-3 (or any successor rule) of the 
Exchange Act.

25.    GOVERNING LAW

       The Plan and all agreements, documents and instruments entered into
pursuant to the Plan shall be governed by and construed in accordance with the
internal laws of the State of California, excluding that body of law pertaining
to conflict of laws.

               1995 INCENTIVE STOCK OPTION PLAN FOR U.S. EMPLOYEES

                           As Adopted February 9, 1995
                             Amended April 20, 1999


                1.       PURPOSE. The purpose of the Plan is to provide 
incentives to attract, retain and motivate eligible persons whose present and 
potential contributions are important to the success of the Company, its 
Parent, Subsidiaries and Affiliates, by offering them an opportunity to 
participate in the Company's future performance through awards of share 
options. Capitalized terms not defined in the text are defined in Section 20.

                2.       SHARES SUBJECT TO THE PLAN.

                         2.1      NUMBER OF SHARES AVAILABLE.  Subject to 
Sections 2.2 and 14 of the Plan, the total number of Shares issued and 
reserved and available for grant and issue pursuant to options under the 
Plan, the UK Employee Share Option Scheme 1996 (the "UK PLAN"), the 1988 U.S. 
Stock Option Plan (the "PRIOR PLAN") and the Company's Inland Revenue 
approved share option scheme (the "INLAND REVENUE PLAN") (the "PLAN", the "UK 
PLAN", the "PRIOR PLAN" and the "INLAND REVENUE PLAN", collectively, the 
"OPTION PLANS"), shall be four million six hundred seventy two thousand and 
seventy one (4,672,071) Shares. As of the Effective Date, options will no 
longer be granted pursuant to the Prior Plan. As of the date of expiration of 
the Inland Revenue Plan in December 1996, options will no longer be granted 
pursuant to the Inland Revenue Plan. Shares shall again be available for 
grant and issue in connection with future awards of options under the Plan 
and the UK Plan if such Shares cease to be subject to an option granted 
pursuant to the Option Plans. To the extent Shares are subject to options 
granted pursuant to the UK Plan, the Inland Revenue Plan or the Prior Plan, 
such Shares shall be unavailable for issue under this Plan until such options 
expire or become unexercisable without having been exercised in full. To the 
extent Shares are subject to options granted pursuant to this Plan, such 
Shares shall be unavailable for issue under the UK Plan until such options 
expire or become unexercisable without having been exercised in full.

                         2.2      ADJUSTMENT OF SHARES.  In the event that 
the number of Shares in issue is changed by a consolidation or sub-division 
of ordinary shares of the Company or any bonus or other capitalization issue 
of ordinary shares or any similar change in the capital structure of the 
Company without consideration, or by a Corporate Transaction (as defined in 
Section 14.1) then, unless such change results in the termination of all 
outstanding Awards as a result of the Corporate Transaction, (a) the number 
of Shares reserved for issue under the Plan and (b) the Exercise Prices of 
and number of Shares subject to outstanding Awards shall be proportionately 
adjusted, subject to any required action by the Board or the shareholders of 
the Company and compliance with applicable securities laws; PROVIDED, 
HOWEVER, that fractions of a Share shall not be issued but shall either be 
paid in cash at Fair Market Value or shall be rounded up to the nearest 
Share, as determined by the Committee; and PROVIDED, FURTHER, that the 
Exercise Price of

any Award may not be decreased to below the U.S. Dollar equivalent of the par 
value of the Shares calculated by reference to the Conversion Rate prevailing 
at the date of exercise of an Award.

                3.       ELIGIBILITY. ISOs (as defined in Section 5 below) 
may be granted only to employees (including officers and directors who are 
also employees) of the Company or of a Parent or Subsidiary of the Company. 
NQSOs (as defined in Section 5 below) may be granted to employees, officers, 
directors, consultants, independent contractors and advisors of the Company 
or any Parent, Subsidiary or Affiliate of the Company; PROVIDED such 
consultants, contractors and advisors render bona fide services not in 
connection with the offer and sale of securities in a capital-raising 
transaction. A person may be granted more than one Award under the Plan. Each 
person is eligible to receive up to an aggregate maximum of five hundred 
thousand (500,000) Shares per fiscal year.

                4.       ADMINISTRATION.

                         4.1      COMMITTEE AUTHORITY.  The Plan shall be 
administered by the Committee. Subject to the general purposes, terms and 
conditions of the Plan, the Committee shall have full power to implement and 
carry out the Plan. The Committee shall have the authority to:

                (a)      construe and interpret the Plan, any Stock Option 
                         Agreement and any other agreement or
                         document executed pursuant to the Plan;

                (b)      prescribe, amend and rescind rules and regulations

                                                        1995 Stock Option Plan

                (k)      make all other determinations necessary or advisable 
                         for the administration of the Plan.

                         4.2      COMMITTEE DISCRETION.  Any determination 
made by the Committee with respect to any Award shall be made in its sole 
discretion at the time of grant of the Award or, unless in contravention of 
any express term of the Plan or Award, at any later time, and such 
determination shall be final and binding on the Company and all persons 
having an interest in any Award under the Plan. The Committee may delegate to 
one or more officers of the Company the authority to grant an Award under the 
Plan to Participants who are not Insiders of the Company.

                         4.3      COMMITTEE REQUIREMENT.  If two or more 
members of the Board are Outside Directors, the Committee shall be comprised 
of at least two members of the Board, all of whom are Outside Directors.

                5. STOCK OPTIONS. The Committee may grant Awards to eligible 
persons and shall determine whether such Awards shall be Incentive Stock 
Options within the meaning of the Code ("ISOs") or Nonqualified Stock Options 
("NQSOS"), the number of Shares subject to the Award, the Exercise Price of 
the Award, the period during which the Award may be exercised, and all other 
terms and conditions of the Award, subject to the following:

                         5.1      FORM OF OPTION GRANT. Each Award granted 
under the Plan shall be evidenced by a Stock Option Agreement which shall 
expressly identify the Award as an ISO or NQSO, and be in such form and 
contain such provisions (which need not be the same for each Participant) as 
the Committee shall from time to time approve, and which shall comply with 
and be subject to the terms and conditions of the Plan.

                         5.2      DATE OF GRANT.  The date of grant of an 
Award shall be the date on which the Committee makes the determination to 
grant such Award, unless otherwise specified by the Committee. The Stock 
Option Agreement and a copy of the Plan will be delivered to the Participant 
within a reasonable time after the granting of the Award.

                         5.3      EXERCISE PERIOD.  Awards shall be 
exercisable within the times or upon the events determined by the Committee 
as in the Stock Option Agreement; PROVIDED, HOWEVER, that no Award shall be 
exercisable after the expiration of ten (10) years from the date the Award is 
granted; and PROVIDED FURTHER that no ISO granted to a person who directly or 
by attribution owns more than ten percent (10%) of the total combined voting 
power of all classes of stock or shares of the Company or any Parent or 
Subsidiary of the Company ("TEN PERCENT SHAREHOLDER") shall be exercisable 
after the expiration of five (5) years from the date the Award is granted. 
The Committee also may provide for the exercise of Awards to become 
exercisable at one time or from time to time, periodically or otherwise, in 
such number or percentage as the Committee determines.

                         5.4      EXERCISE PRICE.  The Exercise Price shall 
be determined by the Committee when the Award is granted subject to the 
following:

                (a)      The Exercise Price shall not be less than 100% of the
                         Fair Market Value of the Shares on the date of grant;
                         PROVIDED, that the Exercise Price of any ISO granted to
                         a Ten Percent Shareholder shall not be less than 110%
                         of the Fair

                                                        1995 Stock Option Plan

                         Market Value of the Shares on the date of grant. 
                         Payment for the Shares subscribed for may be made in 
                         accordance with Section 6 of the Plan.

                (b)      The Exercise Price shall be in U.S. Dollars.

                (c)      The Exercise Price shall not be less than the U.S.
                         Dollar equivalent of the par value of the Shares
                         calculated by reference to the Conversion Rate
                         prevailing at the date of exercise of an Award.

                         5.5      METHOD OF EXERCISE.  Awards may be 
exercised only by delivery to the Company of a written exercise agreement 
(the "EXERCISE AGREEMENT") in a form approved by the Committee (which need 
not be the same for each Participant), stating the number of Shares being 
subscribed for, the restrictions imposed on the Shares, if any, and such 
representations and agreements regarding Participant's investment intent and 
access to information and other matters, if any, as may be required or 
desirable by the Company to comply with applicable securities laws, together 
with payment in full of the Exercise Price for the number of Shares being 
subscribed for.

                         5.6      TERMINATION.  Notwithstanding the exercise 
periods set forth in the Stock Option Agreement, exercise of an Award shall 
always be subject to the following:

                (a)      If the Participant is Terminated for any reason except
                         death or Disability, then Participant may exercise such
                         Participant's Awards only to the extent that such
                         Awards would have been exercisable upon the Termination
                         Date no later than three (3) months after the
                         Termination Date (or such longer time period not
                         exceeding five (5) years as may be determined by the
                         Committee), but in any event, no later than the
                         expiration date of the Awards.

                (b)      If the Participant is terminated because of death or
                         Disability (or the Participant dies within three (3)
                         months of such termination), then Participant's Awards
                         may be exercised only to the extent such Awards would
                         have been exercisable by Participant on the Termination
                         Date and must be exercised by Participant (or
                         Participant's legal representative or authorized
                         assignee) no later than (i) twelve (12) months after
                         the Termination Date in the case of disability or (ii)
                         eighteen (18) months after the Termination Date in the
                         case of death (or such longer time period not exceeding
                         five (5) years as may be determined by the Committee),
                         but in any event no later than the expiration date of
                         the Awards.

                         5.7      LIMITATIONS ON EXERCISE.  The Committee may 
specify a reasonable minimum number of Shares that may be subscribed for on 
any exercise of an Award; PROVIDED that such minimum number will not prevent 
Participant from exercising the Award for the full number of Shares for which 
it is then exercisable.

                         5.8      LIMITATIONS ON ISOS.  The aggregate Fair 
Market Value (determined as of the date of grant) of Shares with respect to 
which ISOs are exercisable for the first time by a Participant during any 
calendar year (under the Plan or under any other incentive stock option plan 
of the Company or any Affiliate, Parent or Subsidiary of the Company) shall 
not exceed

                                                        1995 Stock Option Plan

$100,000. If the Fair Market Value of Shares on the date of grant with 
respect to which ISOs are exercisable for the first time by a Participant 
during any calendar year exceeds $100,000, the Awards for the first $100,000 
worth of Shares to become exercisable in such calendar year shall be ISOs and 
the Awards for the amount in excess of $100,000 that become exercisable in 
that calendar year shall be NQSOs. In the event that the Code or the 
regulations promulgated thereunder are amended after the Effective Date of 
the Plan to provide for a different limit on the Fair Market Value of Shares 
permitted to be subject to ISOs, such different limit shall be automatically 
incorporated herein and shall apply to any Awards granted after the effective 
date of such amendment.

                         5.9      MODIFICATION, EXTENSION OR RENEWAL.  The 
Committee may modify, extend or renew outstanding Awards and authorize the 
grant of new Awards in substitution therefor; provided that any such action 
may not, without the written consent of Participant, impair any of 
Participant's rights under any Award previously granted. Any outstanding ISO 
that is modified, extended, renewed or otherwise altered shall be treated in 
accordance with Section 424(h) of the Code. The Committee may reduce the 
Exercise Price of outstanding Awards without the consent of Participants 
affected by a written notice to them; PROVIDED, HOWEVER, that the Exercise 
Price may not be reduced below the minimum Exercise Price that would be 
permitted under Section 5.4 of the Plan for Awards granted on the date the 
action is taken to reduce the Exercise Price.

                         5.10     NO DISQUALIFICATION.  Notwithstanding any 
other provision in the Plan, no term of the Plan relating to ISOs shall be 
interpreted, amended or altered, nor shall any discretion or authority 
granted under the Plan be exercised, so as to disqualify the Plan under 
Section 422 of the Code or, without the consent of the Participant affected, 
to disqualify any ISO under Section 422 of the Code.

                6. PAYMENT FOR SHARES. Payment for Shares subscribed for 
pursuant to the Plan may be made in cash (by check) or, where expressly 
approved for the Participant by the Committee and where permitted by law:

                (a)      by waiver of compensation due or accrued to Participant
                         for services rendered;

                (b)      provided that a public market for the Shares exists:

                         (1)      through a "same day sale" commitment from
                                  Participant and a broker-dealer that is a
                                  member of the National Association of
                                  Securities Dealers (a "NASD DEALER") whereby
                                  the Participant irrevocably elects to exercise
                                  the Award and to sell a portion of the Shares
                                  so subscribed for in order to pay for the
                                  Exercise Price, and whereby the NASD Dealer
                                  irrevocably commits upon receipt of such
                                  Shares to forward the Exercise Price directly
                                  to the Company; or

                         (2)      through a "margin" commitment from Participant
                                  and a NASD Dealer whereby Participant
                                  irrevocably elects to exercise the Award and
                                  to pledge the Shares so subscribed for to the
                                  NASD Dealer in a margin account as security
                                  for a loan from the NASD Dealer in the

                                                        1995 Stock Option Plan

                                  amount of the Exercise Price, and whereby the 
                                  NASD Dealer irrevocably commits upon receipt 
                                  of such Shares to forward the Exercise Price
                                  directly to the Company; or

                (c)      by any combination of the foregoing.

                7.       WITHHOLDING TAXES.

                         7.1      WITHHOLDING GENERALLY.  Whenever Shares are 
to be issued in satisfaction of Awards granted under the Plan, the Company 
may require the Participant to remit to the Company an amount sufficient to 
satisfy federal, state and local withholding tax requirements prior to the 
delivery of any certificate or certificates for such Shares. Whenever, under 
the Plan, payments in satisfaction of Awards are to be made in cash, such 
payment shall be net of an amount sufficient to satisfy federal, state, and 
local withholding tax requirements.

                         7.2      STOCK WITHHOLDING.  When, under applicable 
tax laws, a Participant incurs tax liability in connection with the exercise 
of any Award that is subject to tax withholding and the Participant is 
obligated to pay the Company the amount required to be withheld, the 
Committee may allow the Participant to satisfy the minimum withholding tax 
obligation by electing to have the Company withhold from the Shares to be 
issued that number of Shares having a Fair Market Value equal to the minimum 
amount required to be withheld, determined on the date that the amount of tax 
to be withheld is to be determined (the "TAX DATE"). All elections by a 
Participant to have Shares withheld for this purpose shall be made in writing 
in a form acceptable to the Committee and shall be subject to the following 
restrictions:

                (a)      the election must be made on or prior to the 
                         applicable Tax Date;

                (b)      once made, then except as provided below, the election
                         shall be irrevocable as to the particular Shares as to
                         which the election is made;

                (c)      all elections shall be subject to the consent or 
                         disapproval of the Committee.

                8.       PRIVILEGES OF STOCK OWNERSHIP.

                         8.1      VOTING AND DIVIDENDS.  No Participant shall 
have any of the rights of a shareholder with respect to any Shares until the 
Shares are issued to the Participant. After Shares are issued to the 
Participant, the Participant shall be a shareholder and have all the rights 
of a shareholder with respect to such Shares, including the right to vote and 
receive all dividends or other distributions made or paid with respect to 
such Shares.

                         8.2      FINANCIAL STATEMENTS.  The Company shall 
provide financial statements to each Participant prior to such Participant's 
subscription for Shares under the Plan, and to each Participant annually 
during the period such Participant has Awards outstanding; provided, however, 
the Company shall not be required to provide such financial statements to 
Participants whose services in connection with the Company assure them access 
to equivalent information.

                9.       TRANSFERABILITY. Subject to Section 4.1(j), Awards 
granted under the Plan, and any interest therein, shall not: (a) be 
transferable or assignable by the Participant, (b) be made subject to 
execution, attachment or similar process, otherwise than by will or by the 
laws of descent and distribution or as consistent with the specific Plan and 
Stock Option Agreement provisions relating thereto or (c) during the lifetime 
of the Participant, be exercisable by anyone other than the Participant, and 
any elections with respect to an Award, may be made only by the Participant.

                10.      CERTIFICATES. All certificates for Shares or other 
securities delivered under the Plan shall be subject to such stock transfer 
orders, legends and other restrictions as the Committee may deem necessary or 
advisable, including restrictions under any applicable federal, state or 
foreign securities law, or any rules, regulations and other requirements of 
the SEC or any stock exchange or automated quotation system upon which the 
Shares may be listed.

                11.      SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. An 
Award shall not be effective unless such Award is in compliance with all 
applicable federal and state securities laws, rules and regulations of any 
governmental body, and the requirements of any stock exchange or automated 
quotation system upon which the Shares may then be listed, as they are in 
effect on the date of grant of the Award and also on the date of exercise or 
other issue. Notwithstanding any other provision in the Plan, the Company 
shall have no obligation to issue or deliver certificates for Shares under 
the Plan prior to (a) obtaining any approvals from governmental agencies that 
the Company determines are necessary or advisable, and/or (b) completion of 
any registration or other qualification of such shares under any state or 
federal law or ruling of any governmental body that the Company determines to 
be necessary or advisable. The Company shall be under no obligation to 
register the Shares with the SEC or to effect compliance with the 
registration, qualification or listing requirements of any state securities 
laws, stock exchange or automated quotation system, and the Company shall 
have no liability for any inability or failure to do so.

                12.      EMPLOYMENT WITH COMPANY.

                         12.1       NO OBLIGATION TO EMPLOY.  Nothing in the 
Plan or any Award granted under the Plan shall confer or be deemed to confer 
on any Participant any right to continue in the employ of, or to continue any 
other relationship with, the Company or any Parent, Subsidiary or Affiliate 
of the Company or limit in any way the right of the Company or any Parent, 
Subsidiary or Affiliate of the Company to terminate Participant's employment 
or other relationship at any time, with or without cause.

                         12.2       NO RIGHT TO COMPENSATION.  In the event 
that any person holding an Award under the Plan ceases to be employed by, or 
otherwise has ceased to provide services to, the Company or a Parent, 
Subsidiary or Affiliate for whatever reason, he shall have no right to any 
compensation in respect of this loss of right to receive Shares under this 
Plan.

                13. EXCHANGE AND BUYOUT OF AWARDS. The Committee may, at any 
time or from time to time, authorize the Company, with the consent of the 
respective Participants, to issue new Awards in exchange for the surrender 
and cancellation of any or all outstanding Awards. The Committee may at any 
time buy from a Participant an Award previously granted

with payment in cash, Shares or other consideration, based on such terms and 
conditions as the Committee and the Participant shall agree.

                14.      CORPORATE TRANSACTIONS.

                         14.1       ASSUMPTION OR REPLACEMENT OF AWARDS BY 
SUCCESSOR. In the event of (a) a sale of the entire share capital of the 
Company to another corporation (whether for consideration in cash or in the 
form of securities of any kind), (b) a dissolution or liquidation of the 
Company, (c) the sale of substantially all of the assets of the Company, or 
(d) any other transaction which qualifies as a "corporate transaction" under 
Section 424(a) of the Code wherein the shareholders of the Company give up 
all of their equity interest in the Company ("CORPORATE TRANSACTION"), any or 
all outstanding Awards may be assumed or replaced by the purchasing or 
successor corporation, which assumption or replacement shall be binding on 
all Participants. In the alternative, the purchasing or successor corporation 
may substitute equivalent Awards or provide substantially similar 
consideration to Participants as was provided to shareholders (after taking 
into account the existing provisions of the Awards). The purchasing or 
successor corporation may also issue, in place of outstanding Shares of the 
Company held by the Participant, substantially similar shares or other 
property subject repurchase restrictions no less favorable to the Participant.

                         14.2       EXPIRATION OF AWARDS.  In the event such 
purchasing or successor corporation, if any, refuses to assume or substitute 
the Awards, as provided above, pursuant to a transaction described in 
Subsection 14.1(a) above, such Awards shall expire on such transaction at 
such time and on such conditions as the Board shall determine. In the event 
such purchasing or successor corporation, if any, refuses to assume or 
substitute the Awards as provided above, pursuant to a corporate transaction 
described in Subsections 14.1(b), (c) or (d) above, or there is no purchasing 
or successor corporation, and if the Company ceases to exist as a separate 
corporate entity, then, notwithstanding any contrary terms in the Stock 
Option Agreement, the Awards shall expire on a date at least twenty (20) days 
after the Board gives written notice to Participants specifying the terms and 
conditions of such termination.

                         14.3       OTHER TREATMENT OF AWARDS.  Subject to 
any greater rights granted to Participants under the foregoing provisions of 
this Section 14, in the event of the occurrence of any Corporate Transaction 
described in Section 14.1, any outstanding Awards shall be treated as 
provided in the applicable agreement or plan of such Corporate Transaction.

                         14.4       ASSUMPTION OF AWARDS BY THE COMPANY.  The 
Company, from time to time, also may substitute or assume outstanding awards 
granted by another company, whether in connection with an acquisition of such 
other company or otherwise, by either (a) granting an Award under the Plan in 
substitution of such other company's award, or (b) assuming such award as if 
it had been granted under the Plan if the terms of such assumed award could 
be applied to an Award granted under the Plan. Such substitution or 
assumption shall be permissible if the holder of the substituted or assumed 
award would have been eligible to be granted an Award under the Plan if the 
other company had applied the rules of the Plan to such grant. In the event 
the Company assumes an award granted by

                                                        1995 Stock Option Plan

another company, the terms and conditions of such award shall remain 
unchanged (EXCEPT that the exercise price and the number and nature of Shares 
issuable upon exercise of any such option will be adjusted appropriately 
pursuant to Section 424(a) of the Code). In the event the Company elects to 
grant a new Award rather than assuming an existing option, such new Award may 
be granted with a similarly adjusted Exercise Price.

                15.      ADOPTION AND SHAREHOLDER APPROVAL. The Plan shall 
become effective at such date and time as the Registration Statement filed 
with the SEC relating to the Company's securities is declared effective (and 
then only provided that the initial public offering later closes) (the 
"EFFECTIVE DATE"). The Plan shall be approved by the shareholders of the 
Company (excluding Shares issued pursuant to this Plan), consistent with 
applicable laws, within twelve months before or after the date the Plan is 
adopted by the Board. Upon the Effective Date, the Board may grant Awards 
pursuant to the Plan; PROVIDED, HOWEVER, that: (a) no Award may be exercised 
prior to initial shareholder approval of the Plan and (b) no Award granted 
pursuant to an increase in the number of Shares approved by the Board shall 
be exercised prior to the time such increase has been approved by the 
shareholders of the Company.

                16.      TERM OF PLAN. The Plan will terminate ten (10) years 
from the date the Plan is adopted by the Board or, if earlier, the date of 
shareholder approval.

                17.      AMENDMENT OR TERMINATION OF PLAN. The Board may at 
any time terminate or amend the Plan in any respect, including without 
limitation amendment of any form of Stock Option Agreement or instrument to 
be executed pursuant to the Plan; PROVIDED, HOWEVER, that the Board shall 
not, without the approval of the shareholders of the Company, amend the Plan 
in any manner that requires such shareholder approval pursuant to the Code or 
the regulations promulgated thereunder as such provisions apply to ISO plans; 
PROVIDED, FURTHER, that no amendment may be made to outstanding Awards 
without the consent of the Participant.

                18.      NONEXCLUSIVITY OF THE PLAN. Neither the adoption of 
the Plan by the Board, the submission of the Plan to the shareholders of the 
Company for approval, nor any provision of the Plan shall be construed as 
creating any limitations on the power of the Board to adopt such additional 
compensation arrangements as it may deem desirable, including, without 
limitation, the granting of stock options otherwise than under the Plan, and 
such arrangements may be either generally applicable or applicable only in 
specific cases.

                19.      GOVERNING LAW. The Plan and all agreements, 
documents and instruments entered into pursuant to the Plan shall be governed 
by and construed in accordance with the internal laws of the State of 
California, excluding that body of law pertaining to conflict of laws.

                20.      DEFINITIONS. As used in the Plan, the following

         circumstances and during the periods set out below:-

5.3.1    if an Option Holder ceases to be employed by the Group by reason of his
         death his Option may be exercised to the extent that his Option would
         have been exercisable at the time of his death within eighteen months
         of his death (or such longer period not exceeding five years as may be
         determined by the Committee) by his legal personal representatives
         provided that such exercise is not later than the Last Exercise Date
         and thereafter the Option shall lapse;

5.3.2    if an Option Holder ceases to be employed by the Group by reason of his
         disability (as determined by the Committee) his Option may be exercised
         to the extent that his Option would have been exercisable at the time
         of his cessation of employment within twelve months of the date of such
         cessation (or such longer period not exceeding five years as may be
         determined by the Committee) provided that such exercise is not later
         than the Last Exercise Date and thereafter the Option shall lapse;

5.3.3    if an Option Holder ceases to be employed by the Group (otherwise than
         by reason of his death or disability) his Option may be exercised to
         the extent that his Option would have been exercisable at the time of
         cessation of his employment within three months of the date of such
         cessation (or such longer period not exceeding five 


                                      7
<PAGE>

         years as may be determined by the Committee) provided that such 
         exercise is not later than the Last Exercise Date and thereafter his 
         Option shall lapse.

5.4      Each Option is to be exercisable by an Option Holder to the extent that
         the Option has become exercisable in whole or in part.

5.5      Exercise of an Option is to be by application in writing addressed to
         the Company and specifying the number of Option Shares in respect of
         which the Option is being exercised on that occasion and the method of
         payment of the Exercise Price for such Option Shares, such application
         to be delivered or sent by prepaid post to the registered office for
         the time being of the Company or to such office as may from time to
         time be specified by the Company in writing to the Option Holder.

5.6      Subject to the regulations and enactments for the time being in force
         under any applicable national or foreign securities law and any rules,
         regulations and other requirements of any stock exchange or automated
         quotation system upon which the Ordinary Shares may be listed or quoted
         and subject to compliance by the Option Holder with the terms of the
         Option the Company will after receipt of the application make an
         allotment to the Option Holder of the number of Ordinary Shares
         specified in the application at the Exercise Price (as adjusted in
         accordance with the provisions of the Scheme) and will (subject to the
         provisions of Rule 5.7) deliver to the Option Holder evidence of title
         to such Ordinary Shares provided that instead of allotting and issuing
         the appropriate number of Ordinary Shares the Company shall have the
         right to satisfy its obligations of allotment by (in whole or in part)
         procuring that some or all of the Ordinary Shares are transferred by a
         third party to the relevant Option Holder. For these purposes delivery
         or transfer to an Option Holder includes delivery or transfer to a
         nominee for the Option Holder provided that the Option Holder acquires
         the beneficial ownership of the Ordinary Shares delivered or
         transferred.

5.7      The Company shall have no obligation to issue or deliver certificates
         for Ordinary Shares under the Scheme prior to:-

5.7.1    obtaining any approvals from governmental agencies that the Company
         determines are necessary or advisable; and

         cash (by cheque) or where expressly approved for the Option Holder by

                      Dealer") whereby the Option Holder irrevocably elects to
                      exercise his Option and to sell a portion of the Ordinary

                      Price, and whereby the NASD Dealer irrevocably commits

                      to exercise his Option and to pledge the Ordinary Shares
                      so subscribed for to the NASD Dealer in a margin account
                      as security for a loan from the NASD Dealer in the amount
                      of the Exercise Price, and whereby the NASD Dealer
                      irrevocably commits upon receipt of such Ordinary Shares
                      to forward the Exercise Price directly to the Company; or


                                      9

         described in Rule 7.1.1 above, refuses to make a proposal as described
         in Rules 7.1.4 to 7.1.6 above to an Option Holder prior to the
         commencement of the earliest of the periods described in Rules 7.2.1.1
         and 7.2.1.2 below, then:-

7.2.1    if his Option has already become capable of exercise under these Rules

7.2.2    if his Option has not already become capable of exercise under these
         Rules then such Option shall lapse at such time and on such conditions
         as the Board shall determine.

                                      11
<PAGE>

7.4      In the event that the Acquiring Company, pursuant to a transaction
         described in Rule 7.1.2 above, refuses to make a proposal as described
         in Rules 7.1.4 to 7.1.6 above to an Option Holder prior to the expiry
         of one month after the Court sanctions the compromise or arrangement
         then his Option shall be subject to the provisions of Rule 7.7.

7.5      In the event that the Acquiring Company, pursuant to a transaction
         described in Rule 7.1.3 above, refuses to make a proposal as described
         in Rules 7.1.4 to 7.1.6 above to an Option Holder then his Option shall
         lapse at such time and on such conditions as the Board shall determine.

7.6      In the event of a members' voluntary winding up of the Company any
         Option Holder may, by notice in writing to the Company within 60 days
         of the commencement of the winding up (such notice being accompanied by
         payment of the Exercise Price), elect in relation to any Option which
         has already become capable of exercise under these Rules to be treated
         as if that Option had been exercised either to the full extent that it
         is then capable of being exercised or to the extent specified in the
         notice, immediately before the commencement of the winding up, and such
         Option Holder shall then be entitled to be paid a sum equal to the
         amount he would have received as a holder of the Ordinary Shares to
         which he would have been entitled upon such exercise. Subject as
         aforesaid, all Options shall lapse on the winding up of the Company.

7.7      If under Section 425 of the Companies Act 1985 it is proposed that the
         court sanctions a compromise or arrangement proposed for the purposes
         of or in connection with a scheme for the reconstruction of the Company
         or its amalgamation with any other company or companies the Company
         shall give notice thereof to all Option Holders at the same time as it
         sends notices to members of the Company summoning the meeting to
         consider such a compromise or arrangement. Then at the time that such
         notice is given:-

7.7.1    if the Option has already become capable of exercise under these Rules,
         the Option Holder may exercise the Option, to the extent that the
         Option has become exercisable, before the expiry of the later of one
         month from the date of such notice 


                                      12
<PAGE>

         and one month from the date on which the Court sanctions the 
         compromise or arrangement and thereafter the Option shall lapse. The 
         exercise of an Option under this Rule 7.7.1 shall be conditional on 
         such compromise or arrangement becoming effective;

7.7.2    if the Option has not already become capable of exercise under these
         Rules the Option shall lapse at such time and on such conditions as the
         Board shall determine.

         It shall be a condition of exercising the Option under this Rule 7.7
         that, after exercising the Option, the Option Holder shall transfer or
         otherwise deal with the Ordinary Shares issued to him so as to place
         him in the same position (or as near as possible) as would have been
         the case if such Ordinary Shares had been subject to such compromise or
         arrangement.

7.8      For the purposes of Rule 7.1.4 above a new option over shares in the
         Acquiring Company (hereinafter called the "New Option") shall be
         equivalent to a subsisting option (hereinafter called the "Old Option")
         if the date of grant is deemed to be the same date as the Date of Grant
         of the Old Option; if the aggregate exercise price of the Ordinary
         Shares subject to the New Option is as nearly as practicable the same
         as the aggregate Exercise Price of the Ordinary Shares subject to the
         Old Option; and (save as provided in the Rules and save for the number,
         description and Exercise Price of the Ordinary Shares subject to the
         New Option) the other rights and terms attaching to the New Option are
         as nearly as practicable the same as those attaching to the Old Option.
         The New Option shall, for all other purposes of the Scheme, be treated
         as having been acquired at the same time as the Old Option.

7.9      With effect from the date on which an Option Holder releases the Old
         Option in consideration of the grant to him of the New Option, Rule 1
         and Rules 5 to 16 inclusive shall, in relation to the New Option, be
         construed for the purposes of that New Option as if references directly
         or indirectly to "the Company" and to "Ordinary Shares" were references
         to the Acquiring Company and to shares in the Acquiring Company.

7.10     Subject to the provisions of Rule 7.1 to 7.9 above, if any of the
         corporate transactions described in such Rules should occur, any
         outstanding Options shall be treated in the manner provided for in the
         applicable agreement or plan of such corporate transaction.

8        VARIATION IN THE SHARE CAPITAL OF THE COMPANY

8.1      On any variation of the share capital of the Company (whether by way of
         capitalisation or rights issue, sub-division or consolidation of the
         Ordinary Shares or a share capital reduction) the Exercise Price and/or
         the number and nominal value of Ordinary Shares comprised in an Option
         and/or the aggregate maximum number of Ordinary Shares available under
         the Scheme may be varied in such manner as the Committee shall
         determine and such decision of the Committee shall be final and binding
         on the Option Holders and the Company subject to written notification
         being given to the Option Holders.

8.2      An adjustment to the Exercise Price shall not be made pursuant to the
         provisions of this Rule 8 which would result in any Option Shares being

         are or may be Insiders then those provisions to the extent possible
