INSIGNIA SOLUTIONS PLC

REDEEMABLE WARRANT

Original Issue Date: October 17, 2002

This Redeemable Warrant (“Warrant”) is issued in connection with and pursuant to that certain Securities Subscription Agreement (the “Subscription Agreement”) dated as of October 17, 2002, by and between INSIGNIA SOLUTIONS PLC, a company incorporated under the laws of England and Wales (the “Company”) and FUSION CAPITAL FUND II, LLC (the “Buyer”).

FOR VALUE RECEIVED, the Buyer, the registered holder hereof, or its permitted assigns (the “Holder”), is entitled to purchase from the Company, during the period specified in this Warrant, 1,000,000 (subject to adjustment as hereinafter provided) fully paid and non-assessable American depository shares (each an “ADS” and collectively, the “ADSs”) of the Company at the purchase price per ADS provided in Section 1.2 of this Warrant (the “Warrant Exercise Price”), all subject to the terms and conditions set forth in this Warrant.  Each ADS represents one ordinary share, 20 pence per share nominal value, of the Company (the “Ordinary Shares”).  The ADSs to be purchased as described above are referred to herein as the “Warrant Shares.”  All terms not otherwise defined herein shall have the meaning ascribed to them in the Subscription Agreement.

Section 1.              Period for Exercise and Exercise Price; Redemption.

1.1          Period for Exercise.  The right to purchase shares of Warrant Shares represented by this Warrant shall be immediately exercisable, and shall expire at 5:00 p.m., Chicago local time, September 30, 2007  (the “Expiration Date”).  From and after the Expiration Date this Warrant shall be null and void and of no further force or effect whatsoever.

1.2          Warrant Exercise Price.  The Warrant Exercise Price per share of Warrant Shares shall be the U.S. Dollar equivalent of 20.5 pence per ADS (subject to adjustment as hereinafter provided), calculated by reference to the average currency conversion rate quoted by the Bank of America in London as the price for Pounds Sterling purchased with U.S. Dollars prevailing at the date the Warrant is exercised. Notwithstanding any provision hereof to the contrary (and in particular any provision relating to adjustment to the Warrant Exercise Price), the Company shall not be required or permitted to issue any Ordinary Shares under this Warrant

1

(or have its transfer agent or Depositary issue any ADSs), if such issuance would breach the Company’s obligations under the United Kingdom Companies Act 1985.

1.3          Redemption.  At any time on or before June 30, 2003, the Company shall have the unconditional right to redeem this Warrant (in whole but not in part) from the Holder for an aggregate Redemption Price of U.S.$200,000 (the “Redemption Price”).  The Company’s redemption rights hereunder shall be exercisable even if the Holder has surrendered this Warrant for exercise in whole or in part, so long as the Company gives written notice to the Holder of the Company’s exercise of its redemption rights hereunder within 2 Trading Days after the Holder has surrendered this Warrant for exercise in whole or in part.  If the Holder has surrendered this Warrant for exercise in whole or in part and the Company has not given written notice to the Holder of the Company’s exercise of its redemption rights hereunder within 2 Trading Days after the Holder has surrendered this Warrant for exercise in whole or in part, then the Company shall have no redemption rights hereunder.  The Company’s redemption rights hereunder shall be exercisable by delivering written notice thereof to the Holder.  The Redemption Price shall be payable in cash within 10 Trading Days after the written notice to the Holder regarding redemption of this Warrant.  In such case, if for any reason or for no reason the Redemption Price is not paid to the Holder within such 10 Trading Days, then the redemption shall be null and void and the Company shall have no future redemption rights hereunder.   Immediately upon receipt of the Redemption Price, the Holder shall surrender this Warrant to the Company.  Upon receipt hereof, the Company shall then immediately cancel this Warrant.

Section 2.              Exercise of Warrant.

2.1          Manner of Exercise.   The Holder may exercise this Warrant, in whole or in part, immediately, but not after the Expiration Date, during normal business hours on any Trading Day by surrendering this Warrant to the Company at the principal office of the Company, accompanied by a Warrant Exercise Form in substantially the form annexed hereto duly executed by the Buyer and by payment of the Warrant Exercise Price for the number of Warrant Shares for which this Warrant is then exercisable, either (i) in immediately available funds, (ii) by delivery of an instrument evidencing indebtedness owing by the Company to the Holder in the appropriate amount, (iii) by authorizing the Company to retain ADSs which would otherwise be issuable upon exercise of this Warrant (subject to and in accordance with Section 2.4 hereof) or (iv) in a combination of (i), (ii) or (iii) above, provided, however, that in no event shall the Holder be entitled to exercise this Warrant for a number of Warrant Shares in excess of that number of Warrant Shares which, upon giving effect to such exercise, would cause the aggregate number of ADSs or Ordinary Shares beneficially owned by the Holder to exceed 9.9% of the outstanding ADSs or Ordinary Shares following such exercise.  For purposes of the foregoing proviso, the aggregate number of ADSs or Ordinary Shares beneficially owned by the Holder shall include the number of ADSs or Ordinary Shares issuable upon exercise of this Warrant with respect to which determination of such proviso is being made, but shall exclude ADSs or Ordinary Shares which would be issuable upon (i) exercise of the remaining, unexercised Warrants beneficially owned by the Holder and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by the Holder subject to a limitation on conversion or exercise analogous to the limitation contained herein.  Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended.  The Holder may waive the foregoing limitation by written

2

notice to the Company upon not less than 61 days prior written notice (with such waiver taking effect only upon the expiration of such 61 day notice period).

2.2          When Exercise Effective.  Each exercise of this Warrant shall be deemed to have been effected on the day on which all requirements of Section 2.1 shall have been met with respect to such exercise.  At such time the person in whose name any certificate for shares of Warrant Shares shall be issuable upon such exercise shall be deemed for all corporate purposes to have become the Holder of record of such shares, regardless of the actual delivery of certificates evidencing such shares.

2.3          Delivery of Certificates.  As soon as practicable after each exercise of this Warrant, and in any event no later than 3 Trading Days after such exercise, the Company will issue Warrant Shares for the number of Warrant Shares to which the Holder is entitled upon such Holder’s submission of the applicable Warrant Exercise Form.

2.4          Cashless Exercise.  The Holder may, by providing notice thereof to the Company along with the Warrant Exercise Form, elect to exercise the Warrant for a number of Warrant Shares determined in accordance with the following formula:

Where:

X = The number of Warrant Shares to be issued to the Holder.

Y = The number of Warrant Shares purchasable under this Warrant (at the date of such exercise).

A = The fair market value of one ADS (or other security for which the Warrant is then exercisable at the date of such exercise).

B = Exercise Price (as adjusted to the date of such exercise).

For purposes of this Section 2.4, the “fair market value” per share shall be the Closing Sale Price of the ADSs for the Trading Day immediately prior to the notice of exercise of the Warrant.  Notwithstanding any provisions herein to the contrary, the “cashless exercise” of the Warrants contemplated hereunder shall not be permitted to the extent that the Company is prohibited under the corporate laws and regulations of England and Wales from effectuating such “cashless exercise” of the Warrants.

Section 3.              Adjustment of Purchase Price and Number of Shares.  The Warrant Exercise Price and the kind of securities issuable upon exercise of the Warrant shall be adjusted from time to time as follows (subject to Section 1.2):

3.1          Subdivision or Consolidation of Shares (Share Splits).  If the Company at any time effects a subdivision or consolidation of the outstanding ADSs or Ordinary Shares (through a split or otherwise), the number of Warrant Shares shall be increased, in the case of a subdivision, or the number of shares of Warrant Shares shall be decreased, in the case of a consolidation, in the same proportions as the ADSs or Ordinary Shares are subdivided or

3

consolidated, in each case effective automatically upon, and simultaneously with, the effectiveness of the subdivision or consolidation which gives rise to the adjustment.

3.2          Dividends.  If the Company at any time pays a dividend, or makes any other distribution, to holders of ADSs or Ordinary Shares payable in ADSs or Ordinary Shares, or fixes a record date for the determination of holders of ADSs or Ordinary Shares entitled to receive a dividend or other distribution payable in Ordinary Shares or ADSs, then the number of shares of Warrant Shares in effect immediately prior to such action shall be proportionately increased so that the Holder hereof may receive upon exercise of the Warrant the aggregate number of ADSs which he or it would have owned immediately following such action if the Warrant had been exercised immediately prior to such action.  The adjustment shall become effective immediately as of the date the Company shall take a record of the holders of ADSs or Ordinary Shares for the purpose of receiving such dividend or distribution (or if no such record is taken, as of the effectiveness of such dividend or distribution).

3.3          Reclassification, Consolidation or Merger.  If at any time, as a result of:

(a)           a capital reorganization or reclassification (other than a subdivision, consolidation or dividend provided for elsewhere in this Section 3), or

(b)           a merger or consolidation of the Company with another corporation (whether or not the Company is the surviving corporation),

the ADSs issuable upon exercise of the Warrants shall be changed into or exchanged for the same or a different number of shares of any class or classes of shares of the Company or any other corporation, or other securities convertible into such shares, then, as a part of such reorganization, reclassification, merger or consolidation, appropriate adjustments shall be made in the terms of the Warrants (or of any securities into which the Warrants are exercised or for which the Warrants are exchanged), so that:

(y)           the Holders of Warrants or of such substitute securities shall thereafter be entitled to receive, upon exercise of the Warrants or of such substitute securities, the kind and amount of shares, other securities, money and property which such Holders would have received at the time of such capital reorganization, reclassification, merger, or consolidation, if such Holders had exercised their Warrants immediately prior to such capital reorganization, reclassification, merger, or consolidation, and

(z)            the Warrants or such substitute securities shall thereafter be adjusted on terms as nearly equivalent as may be practicable to the adjustments theretofore provided in this Section 3.3.

No consolidation or merger in which the Company is not the surviving corporation shall be consummated unless the surviving corporation shall agree, in writing, to the provisions of this Section 3.3. The provisions of this Section 3.3 shall similarly apply to successive capital reorganizations, reclassifications, mergers and consolidations.

3.4          Other Action Affecting ADSs or Ordinary Shares.  If at any time the Company takes any action affecting ADSs or Ordinary Shares, other than an action described in any of Sections 3.1 - 3.3 which could reasonably be expected to have an adverse effect upon the

4

exercise rights of the Warrants, the Warrant Exercise Price or the kind of securities issuable upon exercise of the Warrants, or both, shall be adjusted in such manner to be equitable in the circumstances.

3.5          Notice of Adjustment Events.  Whenever the Company contemplates the occurrence of an event which would give rise to adjustments under this Section 3, the Company shall mail to each Warrant Holder, at least 5 days prior to the record date with respect to such event or, if no record date shall be established, at least 5 days prior to such event, a notice specifying (i) the nature of the contemplated event, and (ii) the date on which any such record is to be taken for the purpose of such event, and (iii) the date on which such event is expected to become effective, and (iv) the time, if any is to be fixed, when the holders of record shall be entitled to exchange their ADSs or Ordinary Shares (or other securities) for securities or other property deliverable in connection with such event.

3.6          Notice of Adjustments.  Whenever the kind or number of securities issuable upon exercise of the Warrants, or both, shall be adjusted pursuant to Section 3, the Company shall deliver a certificate signed by its Chief Executive Officer and by its Chief Financial Officer, setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated (including a description of the basis of any determination hereunder), and the Warrant Exercise Price and the kind of securities issuable upon exercise of the Warrants after giving effect to such adjustment, and shall cause copies of such certificate to be mailed (by first class mail postage prepaid) to each Warrant Holder promptly after each adjustment.

Section 4.              Reservation.  The Company covenants and agrees that it will at all times have authorized, reserve and keep available, solely for issuance and delivery upon the exercise of this Warrant, the number of Ordinary Shares represented by ADSs from time to time issuable upon the exercise of this Warrant.  The Company further covenants and agrees that this Warrant is, and any Warrants issued in substitution for or replacement of this Warrant and all Warrant Shares, will upon issuance be duly authorized and validly issued and, in the case of Ordinary Shares represented by ADSs issuable hereunder, upon issuance will be fully paid and non-assessable and free from all preemptive rights of any shareholder, and from all taxes, liens and charges with respect to the issue thereof.

Section 5.              Ownership, Transfer and Substitution of Warrants.

5.1          Ownership of Warrants.  The Company may treat the person in whose name any Warrant is registered on the register kept at the principal office of the Company as the owner and Holder thereof for all purposes, notwithstanding any notice to the contrary, but in all events recognizing any transfers made in accordance with the terms of this Warrant.

5.2          Transfer and Exchange of Warrants.  Upon the surrender of any Warrant, properly endorsed, for registration of transfer or for exchange at the principal office of the Company, the Company at its expense will execute and deliver to the Holder thereof, upon the order of such Holder, a new Warrant or Warrants of like tenor, in the name of such Holder or as such Holder may direct, for such number of ADSs with respect to each such Warrant, the aggregate number of ADSs in any event not to exceed the number of ADSs for which the Warrant so surrendered had not been exercised.

5

5.3          REGISTRATION RIGHTS.  THE HOLDER OF THIS WARRANT IS ENTITLED TO CERTAIN REGISTRATION RIGHTS WITH RESPECT TO THE WARRANT SHARES ISSUABLE UPON EXERCISE THEREOF.  SAID REGISTRATION RIGHTS ARE SET FORTH IN A REGISTRATION RIGHTS AGREEMENT BY AND BETWEEN THE BUYER AND THE COMPANY.

5.4          Exemption from Registration.  If an opinion of counsel provides that registration is not required for the proposed exercise or transfer of this Warrant or the proposed transfer of the Warrant Shares and that the proposed exercise or transfer in the absence of registration would require the Company to take any action including executing and filing forms or other documents with the Securities and Exchange Commission (the “SEC”) or any state securities agency, or delivering to the Holder any form or document in order to establish the right of the Holder to effectuate the proposed exercise or transfer, the Company agrees promptly, at its expense, to take any such action.  At any time after the registration statement contemplated in Section 4(a) of the Subscription Agreement is declared effective by the SEC, any Warrant Shares issued to the Holder in connection with any exercise of this Warrant shall be issued in certificated form and shall bear no restrictive legend.  At any time before the registration statement contemplated in Section 4(a) of the Subscription Agreement is declared effective by the SEC, any Warrant Shares issued to the Holder in connection with any exercise of this Warrant shall be issued in certificated form and shall bear the following  restrictive legend:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS, OR AN OPINION OF COUNSEL, IN A FORM REASONABLY ACCEPTABLE TO THE COMPANY, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR APPLICABLE STATE SECURITIES LAWS OR UNLESS SOLD PURSUANT TO RULE 144 UNDER SAID ACT.

On the Commencement Date (as defined in the Subscription Agreement), the Company shall cause any restrictive legend on any outstanding Warrant Shares to be removed.

Section 6.              No Rights or Liabilities as Shareholder.  Nothing contained in this Warrant shall be construed as conferring upon the Holder hereof any rights as a shareholder of the Company or as imposing any liabilities on such holder to purchase any securities or as a shareholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company.

Section 7.              Rule 144 Sales.  At the request of any Holder who proposes to sell securities in compliance with Rule 144 of the SEC, the Company will (i) forthwith furnish to such Holder a written statement of compliance with the filing requirements of the SEC as set

6

forth in Rule 144, as such rules may be amended from time to time and (ii) make available to the public and such Holder such information as will enable the Holder to make sales pursuant to Rule 144.

Section 8.              Miscellaneous.

8.1          Amendment and Waiver.  This Warrant may be amended with, and only with, the written consent of the Company and the Holder.  Any waiver of any term, covenant, agreement or condition contained in this Warrant shall not be deemed a waiver of any other term, covenant, agreement or condition, and any waiver of any default in any such term, covenant, agreement or condition shall not be deemed a waiver of any later default thereof or of any default of any other term, covenant, agreement or condition.

8.2          Representations and Warranties to Survive Closing.  All representations, warranties and covenants contained herein shall survive the execution and delivery of this Warrant and the issuance of any Warrant Shares upon the exercise hereof.

8.3          Severability.  In the event that any court or any governmental authority or agency declares all or any part of any Section of this Warrant to be unlawful or invalid, such unlawfulness or invalidity shall not serve to invalidate any other Section of this Warrant, and in the event that only a portion of any Section is so declared to be unlawful or invalid, such unlawfulness or invalidity shall not serve to invalidate the balance of such Section.

8.4          Binding Effect; No Third Party Beneficiaries.  All provisions of this Warrant shall be binding upon and inure to the benefit of the parties and their respective heirs, legatees, executors, administrators, legal representatives, successors, and permitted transferees and assigns.  No person other than the holder of this Warrant and the Company shall have any legal or equitable right, remedy or claim under or in respect of, this Warrant.

8.5          Notices.  Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Warrant must be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by facsimile (provided confirmation of transmission is mechanically or electronically generated and kept on file by the sending party); or (iii) one Trading Day after deposit with a nationally recognized overnight delivery service, in each case properly addressed to the party to receive the same.  The addresses and facsimile numbers for such communications shall be:
