free and clear from all liens, claims and encumbrances, will not be subject to
any preemptive rights or other similar rights of shareholders of the Company and
the Subscriber will acquire good and marketable title to the Shares, free and
clear of all liens, claims and encumbrances. The holders of Ordinary Shares will
not, upon issuance, be subject to personal liability to contribute to the assets
or liabilities of the Company in their capacity as holders of such shares. No
personal liability attaches to the registered holders of Ordinary Shares by
reason of their being registered holders thereof. Upon issuance, the Shares are
entitled to the benefits specified in the corresponding ADRs and in the Deposit
Agreement. The Board of Directors of the Company has approved the issuance of
Shares pursuant to the terms hereof. No further corporate authorization or
approval is required under the rules of Nasdaq with respect to the transactions

                  (b) Upon issue, the Subscriber will acquire good and
marketable title to the Warrants, free and clear of all liens, claims and
encumbrances. The Warrant Shares and the Ordinary Shares represented by such

         4.6 The execution, delivery and performance of this Agreement by the
Company, and the consummation by the Company of the transactions contemplated
hereby (including, without limitation, the issuance and reservation for
issuance, as applicable, of the Shares and the Warrant Shares and the
Subscriber's purchase and acquisition of the Securities) do not and will not (a)
result in a violation of the Memorandum of Association and Articles of
Association, (b) conflict with, or constitute a default (or an event which with
notice or lapse of time or both would become a default) under, or give to others
any rights of termination, amendment, acceleration or cancellation of, any
agreement, indenture or instrument to which the Company or any of its
subsidiaries is a party or (c) result in a violation of any law, rule,
regulation, order, judgment or decree (including, without limitation, United
States of America federal and state securities laws and regulations and the laws
of England and Wales) applicable to the Company or any of its subsidiaries, or
by which any property or asset of the Company or any of its subsidiaries

                                      4

<PAGE>

is bound or affected. Neither the Company nor any of its subsidiaries is in
violation of its Memorandum of Association, its Articles of Association or
other organizational documents, and neither the Company nor any of its
subsidiaries is in default (and no event has occurred which, with notice or
lapse of time or both, would put the Company or any of its subsidiaries in
default) under, nor has there occurred any event giving others (with notice
or lapse of time or both) any rights of termination, amendment, acceleration
or cancellation of, any agreement, indenture or instrument to which the
Company or any of its subsidiaries is a party. The business of the Company
and its subsidiaries is not being conducted, and shall not be conducted so
long as Subscriber owns any of the Securities, in violation of any law,
ordinance, rule, regulation, order, judgment or decree of any governmental
entity, court or arbitration tribunal. Except as set forth on SCHEDULE 4.6,
the Company is not required to obtain any consent, authorization or order of,
or make any filing or registration with, any court or governmental agency or
any regulatory or self-regulatory agency in order for it to execute, deliver
or perform any of its obligations under this Agreement or to perform its
obligations in accordance with the terms hereof. The purchase and acquisition
of the Securities by the Subscriber do not violate any law, rule, regulation,
order, judgment or decree applicable to the Company, or, require further
filing by the Company or Subscriber under such law, rule, regulation, order,
judgment or decree, by virtue of the Company's business or assets. Except as
set forth in the Memorandum, the Company is not in violation of the listing
requirements of Nasdaq and does not reasonably anticipate that the ADSs will
be de-listed by Nasdaq for the foreseeable future, and the Company has made
all necessary filings and notifications with, and obtained all necessary
approvals from, Nasdaq with respect to the transactions contemplated hereby,
including, without limitation, the issuance of the Shares and the Warrant
Shares and the inclusion for quotation of the Shares and the Warrant Shares
on Nasdaq.

         4.7 The Ordinary Shares are registered under Section 12 of the
Securities and Exchange Act of 1934, as amended (the "EXCHANGE ACT"), and have
been so registered since November 13, 1995. Since December 31, 1996, the Company
has timely filed all reports, schedules, forms, statements and other documents

other documents required to be filed by it with the SEC pursuant to the
reporting requirements of the Exchange Act (all of the foregoing filed after

and schedules thereto and documents incorporated by reference therein, being
referred to herein as the "SEC DOCUMENTS" and such documents filed prior to the
date hereof, the "FILED SEC DOCUMENTS"), including for purposes of determining
the availability of Form S-3. The Company has delivered or made available to
Subscriber true and complete copies of the SEC Documents filed since December
31, 1996. As of their respective dates of filing, the Company Reports and the
SEC Documents complied in all material respects with the requirements of the
applicable law and the rules and regulations promulgated thereunder applicable
to such Company Reports and SEC Documents, and none of the Company Reports and
SEC Documents, at the time they were filed with the Companies House or SEC,
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. Except as set forth on SCHEDULE 4.7, none of the statements made in
any such SEC Document is, or, except pursuant to Filed SEC Documents has been,
required to be updated or amended under applicable law. Except as set forth on
SCHEDULE 4.7, the financial statements of the Company included in the SEC
Documents were prepared in accordance with United States of America generally
accepted accounting principles, consistently applied, and the rules and
regulations of the SEC during the periods involved (except (i) as may be
otherwise indicated in such financial statements or the notes thereto or (ii) in
the case of unaudited interim statements, to the extent they do not include
footnotes or are condensed or summary statements) and present accurately and
completely in all material respects the consolidated financial position of the
Company and its consolidated subsidiaries as of the dates thereof and the
consolidated results of their operations and cash flows for the periods then
ended (subject, in the case of unaudited statements, to normal, immaterial
year-end audit adjustments). Except as set forth in the financial statements of
the Company included in the Filed SEC Documents, the Company has no liabilities,
contingent or otherwise, other than (i) liabilities incurred subsequent to the
date of such financial statements in the ordinary course of business consistent
with past practice and (ii) obligations under contracts and commitments incurred
in the ordinary course of business and not required under generally accepted
accounting principles to be reflected in such financial statements. The Filed
SEC Documents contain a complete and accurate list of all material undischarged
written or oral contracts, agreements, leases or other instruments to which the
Company or any subsidiary is a party or by which the Company or any subsidiary
is bound or to which any of the properties or assets of the Company or any
subsidiary is subject (each a "CONTRACT"), except to the extent not required to
be filed pursuant to the applicable

                                      5

<PAGE>

Rules and Regulations of the SEC. None of the Company, its subsidiaries or
any of the other parties thereto, is in material breach or violation of any
Contract. No event, occurrence or condition exists which, with the lapse of
time, the giving of notice, or both, or the happening of any further event or
condition, would become a material breach or default by the Company or its
subsidiaries under any Contract.

         4.8 Except as set forth in the Public Reports, since December 31, 1999,
there has been no material adverse change and no material adverse development in
the business, properties, operations, financial condition, results of operations
or prospects of the Company or any of its subsidiaries.

         4.9 Except as set forth in the Filed SEC Documents and the Memorandum,
there is no action, suit, proceeding, inquiry or investigation before or by any
court, public board, governmental agency or authority, or self-regulatory
organization or body pending or threatened against or affecting the Company, any
of its subsidiaries, or any of their respective directors or officers in their
capacities as such, wherein an unfavorable decision, ruling or finding (i) would
adversely affect the transactions contemplated by this Agreement or any of the
documents contemplated hereby, (ii) would adversely affect the validity or
enforceability of, or the authority or ability of the Company to perform its
obligations under, this Agreement or any of such other documents or (iii) would
adversely affect the business properties, operations and results of operations
or prospects of the Company or any of its subsidiaries. There are no facts
which, if known by a potential claimant or governmental agency or authority,
could give rise to a claim or proceeding.

         4.10 No information relating to or concerning the Company or any of its
subsidiaries set forth in this Agreement or in the Memorandum contains an untrue
statement of a material fact or omits to state a material fact necessary in
order to make the statements made herein or therein, in light of the
circumstances under which they were made, not misleading. Except for the
execution and performance of this Agreement and the transactions contemplated
hereby, no material fact (within the meaning of the federal securities laws of
the United States of America) exists with respect to the Company or any of its
subsidiaries which has not been publicly disclosed, except to the extent not
required to be disclosed pursuant to the applicable Rules and Regulations of the
SEC.

         4.11 The Company acknowledges and agrees that Subscriber is acting
independently and is not acting as a financial advisor or fiduciary of the
Company (or in any similar capacity) with respect to this Agreement or the
transactions contemplated hereby, that this Agreement and the transactions
contemplated hereby, and the relationship between Subscriber and the Company,
are "arm's-length", and that any statement made by Subscriber, or any of its
representatives or agents, in connection with this Agreement or the transactions
contemplated hereby is not advice or a recommendation, is merely incidental to
Subscriber's purchase of the Securities and has not been relied upon in any way
by the Company, its officers, directors or other representatives. The Company
further represents to Subscriber that the Company's decision to enter into this
Agreement and the transactions contemplated hereby has been based solely on an
independent evaluation by the Company and its representatives.

         4.12 The Company is currently eligible to register the resale of the
Shares and the Warrant Shares by the Subscriber in a secondary offering under
General Instruction B3 and B4 of Form S-3 on a registration statement on Form
S-3 under the Securities Act.

         4.13 Neither the Company nor any person acting on behalf of the Company
has conducted any "general solicitation," as described in Rule 502(c) under
Regulation D promulgated under the Securities Act ("REGULATION D"), with respect
to any of the Securities being offered hereby.

         4.14 Neither the Company, nor any of its affiliates, nor any person
acting on their behalf, has directly or indirectly made any offers or sales of
any security or solicited any offers to buy any security under circumstances
that would prevent the parties hereto from consummating the transactions
contemplated hereby pursuant to an exemption from registration under the
Securities Act pursuant to the provisions of Regulation D. The transactions
contemplated hereby are exempt from the registration requirements of the
Securities Act, assuming the accuracy of the representations and warranties
herein contained of Subscriber to the extent relevant for such determination.
The issuance of the Securities to the Subscriber will not be integrated with any
other issuance of the Company's securities (past, current or future) which
requires shareholder approval under the rules of Nasdaq or which would result in
a violation of the Securities Act. The issuance of the Securities to the
Subscriber does not require shareholder approval, including, without limitation,
pursuant to the rules of Nasdaq.

                                      6

         4.15 The Company has taken no action which would give rise to any claim
by any person for brokerage commissions, finder's fees or similar payments by
Subscriber relating to this Agreement or the transactions contemplated hereby,
except for dealings with the Placement Agent (the fees of which shall be borne
solely by the Company).

         4.16 The Company's executive officers and directors have studied and
fully understand the terms of this Agreement and the transactions contemplated
hereby and the nature of the securities being sold hereunder and recognize that
they have a potentially dilutive effect. The board of directors of the Company
has concluded in its good faith business judgment that the issuance of the
Securities as contemplated hereby is in the best interests of the Company.

         4.17 Each of the Company and its subsidiaries owns or possesses
adequate and enforceable rights to use all patents, patent applications,
trademarks, trademark applications, trade names, service marks, copyrights,
copyright applications, licenses, know-how (including trade secrets and other
unpatented and/or unpatentable proprietary or confidential information, systems
or procedures) and other similar rights and proprietary knowledge (collectively,
"INTANGIBLES") used or necessary to conduct its business as now being conducted
and as previously described in the Form 10-K and any subsequently filed reports
on Form 10-Q and Form 8-K. Except as set forth in the Memorandum, to their
respective knowledge, neither the Company nor any subsidiary of the Company
infringes on or is in conflict with any right of any other person with respect
to any Intangibles nor is there any claim of infringement made or threatened by
a third party against or involving the Company or any of its subsidiaries.

         4.18 Neither the Company, nor any of its subsidiaries, nor any
director, officer, agent, employee or other person acting on behalf of the
Company or any subsidiary, has, in the course of his actions for, or on behalf
of, the Company, (i) used any corporate funds for any unlawful contribution,
gift, entertainment or other unlawful expenses relating to political activity,
(ii) made any direct or indirect unlawful payment to any foreign or domestic
government official or employee from corporate funds, (iii) violated or is in
violation of any provision of the United States Foreign Corrupt Practices Act of
1977, as amended or (iv) made any bribe, rebate, payoff, influence payment,
kickback or other unlawful payment to any foreign or domestic government
official or employee. Without limiting the generality of the foregoing, the
Company and its subsidiaries have not directly or indirectly made or agreed to
make (whether or not said payment is lawful) any payment to obtain, or with
respect to, sales other than usual and regular compensation to its or their
employees and sales representatives with respect to such sales.

         4.19 Except for employees who perform purely administrative or
custodial functions, each employee of the Company has executed an agreement
containing non-disclosure, confidentiality and assignment of Intangibles
provisions. Each Key Employee (as defined below) is currently serving the
Company in the capacity disclosed in SCHEDULE 4.19. Except for employees who
perform purely administrative or custodial functions, no employee of the Company
or its subsidiaries is now, or is expected to be, in violation of any material
term of any employment contract, confidentiality, disclosure or proprietary
information agreement, non-competition agreement, or any other contract or
agreement or any restrictive covenant, and the continued employment of each
employee does not subject the Company or any of its subsidiaries to any
liability with respect to any of the foregoing matters. Except for employees who
perform purely administrative or custodial functions, no employee has any
intention to terminate or limit his employment with, or services to, the Company
or any of its subsidiaries, nor is any such employee subject to any constraints

full time and attention to such employment or services. "KEY EMPLOYEES" means
Richard M. Noling, Stephen M. Ambler, Mark E. McMillan, George Buchan, Jonathan
Hoskin, Ronald C. Workman, and Stephen Cobb and any individual who assumes or
performs any of the duties of a Key Employee.

         4.20 The Company is not a Passive Foreign Investment Company ("PFIC")
within the meaning of Section 1297 of the United States Internal Revenue Code of
1986, as amended, and is not likely to become a PFIC.

respect thereof in accordance with the provisions of the Deposit Agreement,

shares of the capital stock of the Company may, under the current laws and

distributions will not be subject to withholding or other taxes under the laws
and regulations of the United Kingdom and are otherwise free and clear of any
other tax, withholding or deduction in the United Kingdom and without the
necessity of obtaining any authorization in the United Kingdom.

         4.24 Except for taxes and duties to be paid by the Company, no stamp or
other issuance of transfer taxes or duties and no capital gains, income,
withholding or other taxes are payable by or on behalf of the Subscriber to the
United Kingdom or any political subdivision or taxing authority thereof or
therein in connection with (i) the deposit with the Depositary of the Shares and
the Warrant Shares by the Company against the issuance of the ADRs evidencing
ADSs or (ii) the sale and delivery by the Company of the Shares, the Warrant
Shares and ADSs to or for the account of the Subscriber.

         4.25 Neither the Company nor any of its subsidiaries has taken,
directly or indirectly any action which was designed to or which has constituted
or which might reasonably be expected to cause or result in stabilization or
manipulation of the price of any security of the Company to facilitate the sale
or resale of the Securities and ADSs.

         4.26 The Company has obtained lock-up agreements in the form set forth
in EXHIBIT B hereto from each of Richard M. Noling, Stephen M. Ambler, George
Buchan, David Jon Hoskin, Mark E. McMillan, Ronald C. Workman, Stephen Cobb,
Nicholas Viscount Bearsted, David G. Frodsham, Vincent S. Pino and Albert E.
Sisto not to sell, offer to sell, contract to sell, hypothecate, grant any
option to sell or otherwise dispose of, directly or indirectly, any ADSs, ADRs,
Ordinary Shares or securities convertible into or unexchangeable or exercisable
for ADSs, ADRs or Ordinary Shares or warrants or other rights to purchase ADSs,
ADRs or Ordinary Shares for a period beginning on November 24, 2000 and ending
on 180 days from November 24, 2000.

         4.27 Except as set forth in the financial statements included in the
Filed SEC Documents, each of the Company and its subsidiaries have timely filed
all requisite United States of America federal, state and other tax returns or
extension requests for all fiscal periods in which such filings were required to
be made. There are no examinations in progress or claims pending against the
Company or any of its subsidiaries for United States of America federal, state
and other taxes (including penalties and interest) for any period or periods
prior to and including December 31, 1999 and no notice of any claim for taxes,
whether pending or threatened, has been received. All taxes due from the Company
and its subsidiaries for any period ended before the date hereof, including
interest and penalties (whether or not shown on any tax return) has been paid.
The amounts shown as accruals for taxes on the financial statements included in
the Filed SEC Documents are sufficient for the payment of all taxes (including
penalties and interest) for all periods ended on or before that date. The
Company and its subsidiaries are not and have not during the last five (5) years
been a party to any tax sharing agreement or agreement of similar effect. The
Company is not and has not during the last five (5) years been a member of any
consolidated group. Except as set forth in the financial statements included in
the Filed SEC Documents, the Company and the subsidiaries have not received,
been denied, or applied for any private letter ruling during the last five (5)
years.

         4.28 The Company and its subsidiaries have all Permits (as
hereinafter defined) required by law or governmental regulations from all
applicable courts, administrative agencies or commissions or other
governmental authorities or instrumentalities, whether in the United States
of America (federal, state or local) or outside of the United States of
America that are necessary to operate such businesses as presently conducted
and all such Permits are in full force and effect, except where the failure
to have any such Permits in full force and effect could not, individually or
in the aggregate, reasonably be expected to have a material adverse effect on
the business, properties, operations and results of operations or prospects
of the Company or any of its subsidiaries. Neither the Company nor any of its
subsidiaries is in default under, or in violation of or noncompliance with,
any of such Permits, except for any such default, violation of or
noncompliance which could not, individually or in the aggregate, reasonably
be expected to have a material adverse effect on the business, properties,
operations and results of operations or

                                      8

<PAGE>

prospects of the Company or any of its subsidiaries. Upon consummation of the
transactions contemplated by this Agreement, each such Permit will remain in
full force and effect and will not create a right of any other person to
terminate or revoke, modify or condition such Permit based on such
consummation. "Permit" means any permit, certificate, consent, approval,
authorization, order, license, variance, franchise or other similar indicia
of authority issued or granted by any court, administrative agency or
commission or other governmental authority or instrumentality, whether in the
United States of America (federal, state or local) or outside of the United
States of America.

         4.29 No Subscriber is subscribing for any securities of the Company on
the Closing Date with terms and conditions different from the terms and
conditions of this Agreement.

         4.30 The Company agrees to file a Form 8-K disclosing this Agreement
and the transactions contemplated hereby with the SEC within three (3) business
days following the Closing Date. Such Form 8-K shall contain as an exhibit this
Agreement and the Warrants. Without limiting any of the Company's obligations
under this Agreement, from and after the Closing Date, neither the Company nor
any person acting on its behalf shall take any action which would adversely
affect any exemptions from registration under the Securities Act with respect to
the transactions contemplated hereby.

         4.31 So long as the Subscriber remains a registered owner of any of the
Securities, the Company shall timely file all reports required to be filed with
the SEC pursuant to the Exchange Act, and the Company shall not terminate its
status as an issuer required to file reports under the Exchange Act even if the
Exchange Act or the rules and regulations thereunder would permit such
termination.

         4.32 For a period of beginning on the Closing Date and ending on the
third (3rd) anniversary of the Closing Date, the Company shall continue the
listing and trading of its ADSs on Nasdaq, the New York Stock Exchange or the
American Stock Exchange, secure and maintain the listing and trading of the
Shares and the Warrant Shares on such exchange or quotation system, and comply
in all respects with the Company's reporting, filing and other obligations under
the by-laws or rules of such exchange or quotation system.

         4.33 The Company shall file a Form D within 15 days of the Closing Date
with respect to the Securities with the SEC as required under Regulation D under
the Securities Act, and shall provide a copy thereof to the Subscriber.

         4.34 The Company agrees to provide the following reports to the
Subscriber until the earlier of (i) the date on which the Subscriber transfers
to a non-affiliate of such Subscriber, assigns or sells all of its Securities or
(ii) the third (3rd) anniversary of the Closing Date: (a) a copy of its Annual
Report on Form 10-K within 90 days of the end of the Company's fiscal year, its
Quarterly Reports on Form 10-Q within 45 days of the end of each fiscal quarter,
any proxy statements and any Current Reports on Form 8-K as each becomes
available and (b) within two (2) days after release, copies of all press
releases issued by the Company or any of its subsidiaries. The Company further
agrees to promptly provide to the Subscriber any information with respect to the
Company, its properties, or its business or the Subscriber's investment as the
Subscriber may reasonably request; PROVIDED, HOWEVER, that the Company shall not
be required to provide the Subscriber any material nonpublic information.

5.       TRANSFER RESTRICTIONS AND REGISTRATION RIGHTS.

         5.1 Subscriber acknowledges that it is acquiring the Securities for its
own account and for the purpose of investment and not with a view to any
distribution or resale thereof within the meaning of the Securities Act and any
applicable state or other securities laws ("STATE ACTS"). The Subscriber further
agrees that it will not sell, assign or transfer the Securities at any time in
violation of the Securities Act or State Acts and acknowledges that, in
acquiring Restricted Securities (as such term is defined under the Securities
Act), it must continue to bear the economic risk of its investment for an
indefinite period of time because of the fact that the Securities have not been
registered under the Securities Act or State Acts, and further acknowledges that
the Securities may not be sold unless subsequently registered under the
Securities Act and State Acts or an exemption from such registration is
available. The Subscriber further acknowledges that the Company is not assuming
any obligation to register the Securities under the Securities Act or State Acts
except as expressly set forth herein. The Subscriber also acknowledges that
appropriate legends reflecting the status of the Securities under the Securities
Act and State Acts

                                      9
<PAGE>

may be placed on the certificates representing such Securities at the time of
their transfer and delivery to the holder thereof.

         5.2 Except as provided hereafter with respect to registration of the
Shares and the Warrant Shares, it shall be a condition to any such transfer that
the Company shall be furnished with an opinion of counsel from the holder of
such Shares and Warrant Shares, reasonably satisfactory to the Company, to the
effect that the proposed transfer would be in compliance with the Securities Act
and State Acts.

         5.3 (a) Within ten (10) days after the Closing Date, the Company shall
use its best efforts to prepare and file with the SEC on one occasion, a
registration statement and such other documents as may be necessary in the
opinion of counsel for the Company, and use its best efforts to have such
registration statement declared effective as soon as possible after the Closing
Date in order to comply with the provisions of the Securities Act so as to
permit the registered resale of the Shares and the Warrant Shares for a period
of three (3) years following the Closing Date by each and every holder of shares
sold in the Offering (the "OFFERING SHARES") who desires to register the resale
of their shares. Within five (5) days after the Closing Date, the Company shall
give each holder of Offering Shares notice at the address of such holder
appearing on the register and transfer records of Company of the Company's
intention to register the resale of such Offering Shares. The obligations of the
Company to give such notice shall be limited to the Subscriber and any entity
which at the time the Offering Shares may have been transferred, which entities,
together with the Subscriber and the Placement Agent, are hereafter referred to
as "OFFERING HOLDERS."

                  (b) If the registration statement referred to in Section
5.3(a) above has not been declared effective by the SEC on or before May 14,
2001, the Company shall promptly issue to the Subscriber .07 ADS for every ADS
purchased in the Offering. In addition, if the registration statement referred
to in Section 5.3(a) is not declared effective by the SEC on or before the last
day of each month thereafter, the Company shall promptly, in each respective
month (and prorated for partial months), issue to the Subscriber .02 ADS for
every ADS purchased in the Offering until the registration statement is declared
effective by the SEC (rounded up to the nearest share after aggregating all
shares held by such Offering Holder). In the event of an issue of further ADSs
pursuant to this Section 5.3(b), the Subscriber shall pay the nominal value of
each Ordinary Share represented by each ADS it receives. The foregoing payment
shall constitute the sole monetary remedy available to the Subscriber in the
event that the Company does not comply with the deadlines set forth in this
Section 5.3(b) with respect to the effectiveness of the registration statement
referred to therein.

         5.4 Notwithstanding the foregoing provisions of this Section 5, the
Company may voluntarily suspend the effectiveness of any such registration
statement for a limited time, which in no event shall be longer than 60
consecutive or non-consecutive days in any 12-month period, if the Company has
been advised in writing by counsel or underwriters to the Company that the
offering of any Offering Shares pursuant to the registration statement would
materially adversely affect, or would be improper in view of (or improper
without disclosure in a prospectus), a proposed financing, a reorganization,
recapitalization, merger, consolidation, or similar transaction involving the
Company. If any event occurs that would cause the registration statement to
contain a material misstatement or omission or not to be effective and usable
during the period that such registration statement is required to be effective
and usable, the Company shall promptly file an amendment to the registration
statement and use its best efforts to cause such amendment to be declared
effective as soon as practicable thereafter. The Offering Holders shall furnish
to the Company such information regarding their holdings and the proposed manner
of distribution thereof as the Company may reasonably request and as shall be
required in connection with any such registration statement. Notwithstanding any
provision contained herein to the contrary, the Company's obligation to include,
or continue to include, Offering Shares in any such registration statement under
this Section 5 shall terminate to the extent such shares are eligible for resale
under Rule 144(k) promulgated under the Securities Act. If the registration
statement registering the Shares and the Warrant Shares for resale is suspended
more than 60 consecutive or non-consecutive days in any 12-month period, the
Company shall promptly issue to the Subscriber .07 ADS for every ADS purchased
in the Offering. In addition, if such suspension or stop order is not lifted on
or before the last day of each month thereafter, the Company shall promptly, in
each respective month (and prorated for partial months), issue to the Subscriber
 .02 ADS for every ADS purchased in the Offering until the registration statement
is declared effective by the SEC (rounded up to the nearest share after
aggregating all shares held by such Offering Holder). In the event of an issue
of further ADSs pursuant to this Section 5.4, the Subscriber shall pay the
nominal value of each Ordinary Share represented by each ADS it receives.

                                      10

         5.5 If and whenever the Company is required by the provisions of this
Agreement to use its best efforts to effect the registration of the Offering
Shares under the Securities Act for the account of an Offering Holder, the
Company will, as promptly as possible:

                  (a) prepare and file with the SEC a registration statement
with respect to such securities and use its best efforts to cause such
registration statement to become and remain effective;

                  (b) prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective and
to comply with the requirements of the Securities Act and the rules and
regulations promulgated by the SEC thereunder relating to the sale or other
disposition of the securities covered by such registration statement;

                  (c) furnish to each Offering Holder such numbers of copies of
a prospectus complying with the requirements of the Securities Act, and such
other documents as such Offering Holder may reasonably request in order to
facilitate the public sale or other disposition of the Offering Shares owned by
such Offering Holder, but such Offering Holder shall not be entitled to use any
selling materials other than a prospectus;

                  (d) use its best efforts to register or qualify the securities
covered by such registration statement under the State Acts as any Offering
Holder shall reasonably request, and do any and all such other acts and things
as may be necessary or advisable to enable such Offering Holder to consummate
the public sale or other disposition of the Offering Shares owned by such
Offering Holder in such states; PROVIDED, HOWEVER, that the Company shall not be
obligated to register or qualify such securities in any jurisdiction in which
such registration or qualification would require the Company to qualify as a
foreign corporation or file any general consent to service of process where it
is not then so qualified or has not theretofore so consented; and

                  (e) provide a transfer agent and Depositary, which may be a
single entity, for the Shares and the Warrant Shares not later than the
effective date of the applicable registration statement.

         5.6 Except as provided below in this Section 5, the expenses incurred
by the Company in connection with action taken by the Company to comply with
this Section 5, including, without limitation, all registration and filing fees,
printing and delivery expenses, accounting fees, fees and disbursements of
counsel to the Company, consultant and expert fees, premiums for liability
insurance, if applicable, obtained in connection with a registration statement
filed to effect such compliance, if applicable, and all expenses, including
counsel fees, for complying with State Acts, shall be paid by the Company. All
fees and disbursements of any counsel, experts, or consultants employed by any
Offering Holder shall be borne by such Offering Holder. The Company shall not be
obligated in any way in connection with any registration pursuant to this
Section 5, for any selling commissions or discounts payable to any underwriter
or broker for securities to be sold by such Offering Holder. It shall be a
condition precedent to the obligation of the Company to take any action pursuant
to this Section 5 that the Company shall have received an undertaking
satisfactory to it from each Offering Holder to pay all expenses required to be
borne by such Offering Holder and to furnish or cause to be furnished to the
Company, specifically for use in the preparation of the registration statement
and prospectus, written information concerning (i) the securities held by such
Offering Holder and any underwriter of such securities, (ii) the intended method
of disposition thereof and (iii) any additional information or documentation as
the Company shall reasonably request and as may be required by administrators of
the Securities Act or State Acts in connection with the action to be taken by
the Company hereunder pursuant to such registration.

         5.7 The Company will (to the extent it is lawful for it to do so)
indemnify and hold harmless each Offering Holder, its officers, directors and
each underwriter of such securities, and any person who controls such Offering
Holder or underwriter within the meaning of Section 15 of the Securities Act,
against all claims, actions, losses, damages, liabilities and expenses, joint or
several, to which any of such persons may become subject under the Securities
Act or otherwise, insofar as such losses, claims, damages, liabilities or
actions arise out of or are based upon (i) any untrue statement of any material
fact contained in any registration statement under which such securities were
registered under the Securities Act, any preliminary prospectus or final
prospectus contained therein, or any amendment or supplement thereof, or arise
out of or are based upon the omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading;
(ii) any violation of United States of America state or federal securities laws
but only to the extent, with respect to this subsection (ii),

                                      11

<PAGE>

that the Offering Holder suffers losses, damages and liabilities with respect
to the Securities such Offering Holder beneficially owns as of the date of
such violation including any Securities sold on the day of such violation;
(iii) any failure by the Company to fulfill and perform any agreement,
covenant or undertaking herein or (iv) any failure or breach of the
representations and warranties of the Company set forth in Section 4 to be
accurate as of the Closing, and will (to the extent it is lawful for it to do
so) promptly reimburse such Offering Holder, its officers, directors and each
underwriter of such securities, and each such controlling person or entity
for any legal and any other expenses reasonably incurred by such Offering
Holder, such underwriter, or such controlling person or entity in connection
with investigating or defending any such loss, action, claim, damage,
liability or action; PROVIDED, HOWEVER, that the Company will not be liable
in any such case to the extent that any such loss, claim, damage, liability
or action arises directly out of or is based primarily upon an untrue
statement or omission made in said registration statement, said preliminary
prospectus or said prospectus, or said amendment or supplement in reliance
upon and in conformity with written information furnished to the Company by
such Offering Holder or such underwriter specifically for use in the
preparation thereof, and PROVIDED FURTHER, HOWEVER, that the Company will not
be liable in any such case to the extent that any such loss, claim, damage or
liability or action arises directly out of or is based primarily upon an
untrue statement or omission made in any preliminary prospectus or final
prospectus if (i) such Offering Holder failed to send or deliver a copy of
the final prospectus or prospectus supplement with or prior to the delivery
of written confirmation of the sale of the Offering Shares and (ii) the final
prospectus or prospectus supplement would have corrected such untrue
statement or omission.

         5.8 In the event of any registration of any securities under the
Securities Act pursuant to this Section 5, each Offering Holder will (to the
extent it is lawful to do so), or will furnish the written undertaking of such
other person or entity as shall be acceptable to the Company to, indemnify and
hold harmless the Company, its officers, directors and any person who controls
the Company within the meaning of Section 15 of the Securities Act, against any
losses, claims, damages, liabilities, or actions, joint or several, to which the
Company, its officers, directors, or such controlling person or entity may
become subject under the Securities Act or otherwise, insofar as such losses,
claims, damages, liabilities, or actions arise out of or are based upon any
untrue statement of any material fact contained in any registration statement
under which such securities were registered under the Securities Act, any
preliminary prospectus or final prospectus contained therein, or any amendment
or supplement thereto, or arise out of or are based upon the omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, in each case to the extent and only to the
extent that any such loss, claim, damage, liability, or action arises out of or
is based upon an untrue statement or omission made in said registration
statement, said preliminary prospectus or said prospectus or said amendment or
supplement in reliance upon and in conformity with written information furnished
to the Company by such Offering Holder or any underwriter of such Offering
Holder's securities specifically for use in the preparation thereof, and will
(to the extent it is lawful to do so) promptly reimburse the Company, its
officers, directors and any person who controls the Company within the meaning
of Section 15 of the Securities Act in connection with investigating or
defending any such loss, action, claim, damage, liability or action; PROVIDED,
HOWEVER, that the aggregate amount which any such Offering Holder shall be
required to pay pursuant to this Section 5.8 shall be limited to the dollar
amount of the net proceeds received by such Offering Holder upon the sale of the
Securities pursuant to the registration statement giving rise to such claim.
Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of the Company, its officers, directors and
any person who controls the Company within the meaning of Section 15 of the
Securities Act, and shall survive the transfer of the Securities by such
Offering Holder.

         5.9 At any time when a prospectus relating to the Offering is required
to be delivered under the Securities Act, the Company will promptly notify the
Offering Holder of the happening of any event, upon the notification or
awareness of such event by an executive officer of the Company, as a result of
which the prospectus included in such registration statement, as then in effect,
includes an untrue statement of material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading in light of the circumstances then existing.

         5.10 Any party entitled to indemnification hereunder will (i) give
prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification and (ii) unless in such indemnified party's
reasonable judgment a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. If such defense is assumed, the
indemnifying party will not be subject to any liability for any settlement made
by the indemnified party without its consent (which consent may not be

                                      12

<PAGE>

unreasonably withheld). An indemnifying party who is not entitled to, or elects
not to, assume the defense of a claim will not be obligated to pay the fees and
expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment
of any indemnified party a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
claim.

         5.11 With a view to making available to the Offering Holder the
benefits of Rule 144 promulgated under the Securities Act, the Company agrees
that it will use its best efforts to maintain registration of its Ordinary
Shares represented by ADSs under Section 12 or 15 of the Exchange Act and to
file with the SEC in a timely manner all reports and other documents required to
be filed by an issuer of securities registered under the Exchange Act so as to
maintain the availability of Rule 144 promulgated under the Securities Act. Upon
the request of any record owner, the Company will deliver to such owner a
written statement as to whether it has complied with the reporting requirements
of Rule 144 promulgated under the Securities Act.

Jefferies & Company, Inc.

San Francisco, CA 94108

Ladies and Gentlemen:

         In consideration of the benefits gained by the undersigned in
connection with the private placement (the "PRIVATE PLACEMENT"), with Jefferies
& Company, Inc. ("JEFFERIES") acting as placement agent (the "PLACEMENT AGENT")
of the American depositary shares (the "ADSs"), each ADS representing one
ordinary share of the 20 pence each nominal value (the "ORDINARY SHARES") of
Insignia Solutions plc, a public limited company organized and existing under
the laws of England and Wales (the "COMPANY") on the date hereof, and for other
good and valuable consideration, receipt of which is hereby acknowledged, the
undersigned hereby agrees, for a period beginning on the date hereof and ending
on the date which is the later to occur of (x) 180 days after the closing of the
Private Placement or (y) the date the Securities and Exchange Commission
declares the registration statement filed by the Company as required pursuant to
certain registration rights granted to the Investors to register ADSs purchased
in the Private Placement effective (the "LOCK-UP PERIOD"), not to sell, offer to
sell, solicit an offer to buy, contract to sell, exercise, encumber, distribute,
pledge, grant any option for the sale of, or otherwise transfer or dispose of,
directly or indirectly, in one or a series of transactions (collectively, a
"DISPOSITION"), any ADSs, American depositary receipts ("ADRs") or Ordinary
Shares, any options or warrants to purchase any ADSs, ADRs or Ordinary Shares or
any securities convertible or exercisable into or exchangeable for ADSs, ADRs or
Ordinary Shares (collectively, "SECURITIES"), not owned or hereafter acquired by
the undersigned or with respect to which the undersigned has acquired or
hereafter acquires the power of disposition, without the prior written consent
of Jefferies. Notwithstanding the foregoing, however, the undersigned may make a
Disposition in connection with a bona fide tender offer by a non-affiliated
third party of the Company or the undersigned (the "OFFEROR") for at least 50%
of the equity securities of the Company by tendering the undersigned's
beneficially owned securities to the Offeror.

         The undersigned acknowledges and agrees that the restrictions above are
expressly agreed to preclude the holder of the Securities from engaging in any
hedging or other transaction which is designed to or reasonably expected to lead
to or result in a Disposition of Securities (or the economic equivalent thereof)
during the Lock-Up Period even if such Securities would be disposed of by
someone other than the undersigned. Such prohibited hedging or other
transactions would include, without limitation, any short sale (whether or not
against the box) or

any purchase, sale or grant of any right (including without limitation, any put
or call option) with respect to any Securities or with respect to any security
(other than a broad-based marked basket or index) that includes, relates to or
derives any significant part of its value from the Securities.

         The undersigned hereby also agrees and consents to the entry of stop
transfer instructions with the Company's transfer agent against the transfer of
the Securities held by the undersigned except in compliance with this Lock-Up
Agreement.

         The undersigned hereby represents and warrants as of the date hereof to
the Placement Agent and the Company that this Lock-Up Agreement has been duly
executed and delivered, and this Lock-Up Agreement constitutes a valid and
binding obligation of the undersigned, enforceable in accordance with its terms.

         This Lock-Up Agreement shall be governed by and construed in accordance
with the laws of the State of New York (without giving effect to its conflict of
laws provisions).


                                                Very truly yours,


                                                Name:
