2.    Sale of Sale Shares
      -------------------

2.1   Subject to the terms of this Agreement and with effect from the Completion
      Date, each of the Vendors shall sell with full title guarantee and the
      Purchaser shall purchase, free from all liens, charges and encumbrances
      and together with all rights now or hereafter attaching to them, including
      all rights to any dividend or other distribution declared, made or paid
      after the date of this Agreement, the number of Sale Shares set opposite

                                      12
<PAGE>

2.2   Each of the Vendors hereby waives and agrees to procure the waiver of any
      restrictions on transfer (including pre-emption rights) which may exist in
      relation to the Company Shares and HSBC Notes, whether under the articles
      of association of the Company, the Shareholders' Agreement, the
      instruments constituting the HSBC Notes or otherwise.

2.3   The Purchaser undertakes following Completion to procure that the Company
      pays to the Inland Revenue the sums equal to the amounts on account of
      National Insurance Contributions and Income Tax which have been withheld
      from the Optionholders who are employees pursuant to the provisions of the
      Option Surrender Agreements.

3.    Consideration
      -------------

3.1   Subject to the provisions of this clause, the Consideration for the Sale
      Shares attributable to each Vendor shall be that amount of the Cash
      Component and the Shares Component as shall be set out in columns (3) and
      (4) of Schedule 1A, as calculated in accordance with Schedule 1C and, if
      due pursuant to this Agreement, the Earnout Component.

3.2   A pro forma example (extracted from the attached Excel spreadsheet in the
      approved terms) of the allocation of the Cash Component, Shares Component,
      Escrow Shares and Earnout Component among each of the Vendors, Non-
      Principal Shareholders and Optionholders is set out in Schedule 1C. The
      basis used to calculate the numbers in that pro-forma example is set out
      in that Schedule. The sale of the Company Shares, other than the Sale
      Shares, is dealt with by the Non-Principal Share Purchase Agreement and
      not this Agreement.

3.3   At any time prior to the date two days before the Completion Date, the
      Purchaser may give notice to the Vendors' Solicitors in writing that,
      instead of delivering New OpenTV Shares at Completion, it will deliver
      cash in Pounds Sterling in lieu of such New OpenTV Shares, in relation to
      any proportion of such New OpenTV Shares up to and including 100% of such
      New OpenTV Shares. If the Purchaser delivers such notice, the Purchaser's
      obligations to deliver such New OpenTV Shares (and, if

                                      13
<PAGE>

      applicable, the Escrow Shares) shall be replaced with an obligation to
      deliver cash in Pounds Sterling for the relevant number of New OpenTV
      Shares on the basis of the (Pounds)10.43 for each New OpenTV Share (or
      such other Pounds Sterling amount as the Purchaser's Accountants determine
      to be fair and reasonable in the event of any consolidation, sub-division,
      stock split or reclassification or reduction of the share capital of the
      Purchaser or any rights issue, taking place after the date of this
      Agreement). If the Purchaser exercises its rights under this clause 3.3,
      the additional cash payable in accordance with this clause 3.3 shall be
      allocated amongst the Vendors in proportion to that part of the Total
      Consideration payable to them respectively.

3.4   The Purchaser shall deliver to the Vendors' Solicitors following the close
      of the NASDAQ National Market on the day prior to Completion:

3.4.1        a schedule in the form of the pro-forma example in Schedule 1C,
             together with the supporting Excel spreadsheet, but with the
             insertion of the final amounts of all figures stated to be the
             variables and all the adjustments to be made as a result of the
             variables and adjusted for any assumptions of fact expressly used
             in the Excel spreadsheet which prove to be incorrect at Completion
             and any errors in calculations in the Excel spreadsheet ("Adjusted
             Spreadsheet"); and

3.4.2        a form of Schedules 1A and 1B showing the Total Consideration and
             the allocation of the Cash Component, Shares Component and Escrow
             Shares amongst each of the Vendors, Non-Principal Shareholders and
             Optionholders by reference to the Adjusted Spreadsheet.

3.5   Together, the Adjusted Spreadsheet, Schedules 1A and 1B and the
      calculations of the Total Consideration, Cash Component, Shares Component
      and Escrow Shares are referred to in this Agreement as the "Completion
      Schedules and Calculations".

3.6   The Consideration shall be payable on Completion in accordance with clause
      6.3 on the basis of the Completion Schedules and Calculations and shall be
      adjusted in accordance with clause 3.8.

                                      14
<PAGE>

3.7   The parties acknowledge that it will not be possible to finalise the
      Completion Schedules and Calculations until the Completion Date as a
      result of adjustments of variables which can only be known immediately
      prior to the Completion Date. The Purchaser shall have control over the
      Completion Schedules and Calculations (although the Purchaser shall
      consult with Jasper Smith as representative of the Vendors in relation to
      their preparation) and Completion shall be effected on the basis of the
      Completion Schedules and Calculations prepared by the Purchaser in
      accordance with the provisions of Schedule 1C, PROVIDED THAT the Vendors'
      sole and exclusive remedy in relation to a breach of that obligation to
      prepare the Completion Schedules and Calculations shall be the remedies
      set out in the remainder of this clause 3.7. The Vendors (for and on
      behalf of themselves and/or the Non-Principal Shareholders and
      Optionholders) and the Purchaser shall have the right to object to the
      Completion Schedules and Calculations used to effect Completion during the
      period expiring on the date fifteen (15) days after the Completion Date by
      notice to each other. For the avoidance of doubt, the Non-Principal
      Shareholders and Optionholders shall not have any right to object to such
      Completion Schedules and Calculations directly, but may do so through the
      Vendors. Any matter not objected to by the Vendors (either for themselves
      and/or on behalf of the Non-Principal Shareholders and Optionholders) or
      the Purchaser within such fifteen (15) day period shall be deemed to be
      agreed between the parties and final and binding on the Non-Principal
      Shareholders and Optionholders. The parties shall use their best
      endeavours to resolve any disagreements between them no later than five
      (5) business days after such date of notification. Should disagreements
      still exist at such time, the parties shall appoint an expert (acting as
      an expert not an arbitrator) to resolve such disagreements (and failing
      agreement on the appointment of the expert, the President of the Institute
      of Chartered Accountants in England and Wales shall make such appointment)
      with a view to the resolution of all disagreements no later than thirty
      five (35) business days after the Completion Date. The decision of such
      expert shall, save in the case of manifest error, be final and binding on
      the parties.

3.8   Upon the agreement of, or resolution of any disagreements in relation to,
      the adjustments to the Completion Schedules and Calculations, the Adjusted
      Spreadsheet, Total Consideration, Cash Component, Shares Component, Escrow
      Shares and Schedules 1A and 1B shall be adjusted accordingly.

3.9    The Vendors acknowledge that their respective Consideration for their
       Sale Shares as set out in Schedule 1A shall be adjusted to reflect:

3.9.1        the effect of any notice served by the parties in accordance with
             clause 3.3; and

3.9.2        the revised Schedule 1A which arises from clause 3.8.

3.10   Within seven days of the determination of the Completion Schedules and
       Calculations in accordance with clause 3.8:

3.10.1       if, according to the Completion Schedules and Calculations, any
             Vendor has received too little Consideration, the Purchaser will,
             for the account of the relevant Vendor:

3.10.1.1                 pay to the Vendors' Solicitors (whose receipt shall be
                         an absolute discharge therefore) an amount in Pounds
                         Sterling equal to the Cash Component element of such
                         shortfall and, if applicable, interest thereon as
                         specified in clause 3.11; and

3.10.1.2                 cause to be issued or transferred New OpenTV Shares
                         (valued at (Pounds)10.43 per New OpenTV Share) equal to
                         the Shares Component element of such shortfall (but
                         excluding any fractional entitlements) and cause OpenTV
                         Certificates representing such New OpenTV Shares (as
                         defined in clause 6.3.2 below) to be delivered to the
                         Vendors' Solicitors in accordance with the provisions
                         of clause 6.3.2, subject to clause 7.3.

3.10.2       if, according to the Completion Schedules and Calculations, any
             Vendor has received too much Consideration, such Vendor will:

3.10.2.1                 pay to the Purchaser an amount in Pounds Sterling equal
                         to the Cash Component element of such excess and, if
                         applicable, interest thereon as specified in clause
                         3.11; and

                                      16
<PAGE>

3.10.2.2     transfer to the Purchaser New OpenTV Shares (valued at
             (Pounds)10.43 per New OpenTV Share) equal to the Shares Component
             element of such excess (but excluding any fractional entitlements)
             and cause OpenTV Certificates (as defined in clause 6.3.2 below)
             representing such New OpenTV Shares to be delivered to the

          provided that if the Purchaser remedies the relevant breach within
          seven (7) business days of such request, the provisions of clauses

       restrictions required by clauses 7 and 9) shall not apply to a transfer
       by way of gift:

8.3.1     to a member of the family of the Vendor (meaning the wife, husband,

<PAGE>

     agreed in terms reasonably acceptable to the Purchaser to be bound by the

9.   Escrow
     ------

9.1  On the Completion Date, the Purchaser shall transfer that number of New
     OpenTV Shares (valued at (Pounds)10.43 per share) which is equal to 15% of
     the Consideration payable on Completion on account of the Vendors in an
     amount equal to their proportionate Consideration to be registered in the
     name of, and be deposited with an escrow agent (the "Escrow Agent"), whose
     receipt shall be an absolute discharge therefor, such deposit to constitute
     the escrow fund (the "Escrow Fund") and to be governed by this Agreement
     and the Escrow Agreement.

9.2  Such Escrow Shares together with any cash paid pursuant to clause 9.1 shall
     constitute the "Escrow Fund".  In the event that the Purchaser is entitled
     to recover any amount under this agreement for an Agreed Claim, pursuant to
     clause 10.7 or pursuant to clause 19.2, the Escrow Fund shall be used to
     satisfy the liabilities of the Vendors.

                                      33
<PAGE>

9.3    The Escrow Fund shall continue to be held by the Escrow Agent until its
       termination which shall happen upon the latest to occur of the following:

9.3.1     one year after the Completion Date;

9.3.2     the date of the exhaustion of the Escrow Fund as a consequence of
          transfers to the Purchaser as a result of Agreed Claims; and

9.3.3     where the Purchaser has made a Notified Claim during the period one
          year after the Completion Date, the date when there is a final
          determination of whether such claim becomes an Agreed Claim and such
          claims (to the extent that they, in fact, become Agreed Claims) have
          been fully satisfied out of the Escrow Fund.

9.4    The Purchaser shall not unreasonably withhold its consent to the release
       of some of the Escrow Shares and cash in Pounds Sterling, if any, after
       the expiry of the date one year after the Completion Date if, in the
       Purchaser's reasonable opinion, the remaining Escrow Shares or cash held
       after such release are reasonably adequate to cover potential liabilities
       in relation to claims formerly notified. Any such Escrow Shares or cash
       released shall be dealt with pursuant to clause 9.5 as if they had been
       released upon a termination of the Escrow Fund.

9.5    Upon the Escrow Fund terminating, the Escrow Agent shall deliver to the
       Vendors all Escrow Shares and other property remaining in the Escrow
       Fund. Deliveries of Escrow Shares to Vendors pursuant to this clause 9.5
       and the Escrow Agreement shall be made in proportion to their respective
       original contributions to the Escrow Fund.

9.6    All Notified Claims shall be resolved by mutual agreement amongst the
       parties within 90 days of notification, if possible, failing which by
       arbitration in accordance with the rules of the London Court of
       International Arbitration, with the seat of arbitration in London,
       England.

10.       Completion Accounts
          -------------------

10.1      The Vendors shall procure that within 30 days of Completion draft
          consolidated accounts for the Group as at 30 June 2001 shall be
          prepared in accordance with the provisions of Schedule 9.

10.2      Following the preparation of such draft accounts, the Company shall
          submit them to the Purchaser's Accountants who shall conduct an audit
          applying the same basis and principles referred to in Schedule 9. The
          Vendors shall make the working papers available to the Purchaser's
          Accountants if required by them in carrying out their review.

10.3      If the Purchaser's Accountants agree to the form and content of the
          draft accounts within 60 days of the date on which the drafts were
          submitted (or within such other period as the Vendors and the
          Purchaser may agree), the accounts as so agreed shall be the
          Completion Accounts, but such agreement shall be without prejudice to
          the Purchaser's right to claim under the Warranties, the Tax
          Warranties or otherwise in respect of any matter.

10.4      If the Purchaser's Accountants are not able to agree the form and
          content of the accounts within 60 days of the date on which the drafts
          were first submitted (or within such other period as the Vendors and
          the Purchaser may agree), the matter may be referred by the Vendors or
          the Purchaser to an independent firm of chartered accountants selected
          by agreement between the Vendors and the Purchaser or, failing
          agreement, nominated by the President for the time being of the
          Institute of Chartered Accountants in England and Wales on the
          application of either the Vendors or the Purchaser and:

10.4.1         such independent firm of chartered accountants shall be requested
               to settle any matter in dispute, applying the same basis and
               principles as are referred to in clause 10.1 and Schedule 9 and
               (unless both the Vendors and the Purchaser shall otherwise direct
               in writing) determine the form and content of the Completion
               Accounts; and

                                      35
<PAGE>

10.4.2         the decision of such firm of chartered accountants as to the
               matter in dispute and their determination (if any) as to the form
               and content of the Completion Accounts shall be final and binding
               on the parties hereto and such chartered accountants shall be
               deemed to act as experts and not as arbitrators.

10.5      The costs incurred by the Vendors in respect of the preparation and
          determination of the Completion Accounts shall be borne by the Vendors
          other than the costs of the Purchaser's Accountants which shall be an
          adjustment to the Total Consideration (through the deduction of the
          Interim Bridge Loan in accordance with Schedule 1C). The costs of the
          independent chartered accountant, if any, shall be borne by the
          Vendors and the Purchaser equally.

10.6      Within 7 days of the determination of the Completion Accounts in
          accordance with clauses 10.3 or 10.4 if the amount of the net current
          assets (being current assets less current liabilities) shown in the
          Completion Accounts is less than the amount of the net current assets
          as shown in the Projected Completion Balance Sheet ("Target Net
          Current Assets"), the Vendors will pay in cash to the Purchaser,
          subject to clause 10.7, an amount equal to their aggregate several
          liability (as set out in clause 1.10) of such shortfall and interest
          thereon as specified in clause 10.8. If the Completion Accounts
          reflect a different treatment of employer's NIC liability and payments
          in connection with the surrender of Options than do the draft accounts
          provided by the Vendors pursuant to clause 10.1, such difference shall
          be ignored for the purposes of determining the net current assets
          shown in the Completion Accounts for purposes of this clause 10.6.

10.7      In the event that the shortfall and interest referred to in clause
          10.6 is an amount less than or equal to 10% of the Target Net Current
          Assets, the Vendors shall in accordance with the Escrow Agreement, on
          demand by the Purchaser, authorise the Escrow Agent to transfer to the
          Purchaser that number of Escrow Shares (ignoring fractional
          entitlements) valued at the last sale price listed on the NASDAQ
          National Market on the date prior to such transfer as is equal to
          their aggregate several liability (as set out in clause 1.10) of such
          shortfall and interest, but if the Escrow Fund is not sufficient to
          cover such shortfall and interest, or, to the extent that the
          shortfall and interest referred to in clause 10.6 is in excess of 10%
          of the Target Net Current

                                      36
<PAGE>

          Assets, the Vendors shall be liable to pay their aggregate several
          liability (as set out in clause 1.10) of such shortfall and interest
          in cash.

10.8      The interest payable on the amount of any shortfall pursuant to clause
          10.6 shall accrue from day to day and be compounded at monthly
          intervals at the rate of the base rate from time to time of National
          Westminster Bank Plc, from and including the Completion Date to the
          date of payment.

               time during the period of six months immediately preceding
               Completion (whether or not such person would commit a breach of
               contract by reason of leaving such employment or engagement);

11.1.4         he will not at any time hereafter make use of or disclose or
               divulge to any person (other than to officers or employees of the
               Company or any of the Subsidiaries whose province it is to know
               the same) any information (other than any information properly
               available to the public or disclosed or divulged pursuant to an
               order of a court of competent jurisdiction) relating to any
               member of the Group, the identity of its customers and suppliers,
               its products, finance, contractual arrangements, business or
               methods of business and shall use his best endeavours to prevent
               the publication or disclosure of any such information by any
               person, firm or company with which he is connected;

11.1.5         if, in connection with the business or affairs of any member of
               the Group, he shall have obtained Confidential Information
               belonging to any third party under an agreement purporting to
               bind any member of the Group which contained restrictions on
               disclosure he will not without the previous written consent of
               the Board of Directors of the Purchaser at any time infringe such
               restrictions;

11.1.6         he will not at any time hereafter in relation to any trade,
               business or company use a name or trade mark including the word
               "PlayJam" or any other business product name owned by any member
               of the Group or any word confusingly similar thereto in such a
               way as to be capable of or likely to be confused with the name or
               any trade mark of any member of the Group and shall use his

                                      38
<PAGE>

               reasonable endeavours to procure that no such name or trade mark
               shall be used by any person, firm or company with which he is
               connected.

11.2      Each Vendor and Mr. Bustin shall procure that all companies and
          businesses directly or indirectly owned or controlled by him shall be
          bound by and observe the provisions of this clause 11 as if they were
          parties covenanting with the Purchaser in the same terms.

11.3      While the restrictions contained in this clause 11 are considered by
          the parties to be reasonable in all the circumstances, it is
          recognised that restrictions of the nature in question may fail for
          technical reasons and accordingly it is hereby agreed and declared
          that if any of such restrictions shall be adjudged to be void as going
          beyond what is reasonable in all the circumstances for the protection
          of the interests of the Purchaser but would be valid if part of the
          wording thereof were deleted or the periods thereof reduced or the
          range of activities or area dealt with thereby reduced in scope the
          said restriction shall apply with such modifications as may be
          necessary to make it valid and effective.

11.4      The restrictions contained in clauses 11.1 and 11.2 shall not preclude
          the Vendors and Mr. Bustin from owning OpenTV Shares.

12.       Warranties
          ----------

12.1.1         Each of the Vendors severally represents, warrants and undertakes
               to and with the Purchaser that each of the statements set out in
               Schedule 5 (other than Warranty 15.1) is now true and accurate.

12.1.2         MT&G represents, warrants and undertakes to and with the
               Purchaser that each of the statements set out in Warranty 15.1 is
               now true and correct.

12.2      The Warranties are given subject to matters fairly disclosed in the
          Disclosure Letter but no other information relating to the Company or
          the Subsidiaries of which the Purchaser has knowledge (actual or
          constructive) and no investigation by or on behalf of the Purchaser
          shall prejudice any claim made by the Purchaser under the

                                      39
<PAGE>

          Warranties or operate to reduce any amount recoverable, and liability
          of the Vendors in respect thereof shall not be confined to breaches
          discovered before Completion. No letter, document or other
          communication shall be deemed to constitute a disclosure for the
          purposes of this Agreement unless it is contained in the Disclosure
          Bundle.

12.3      The Vendors acknowledge that the Purchaser has entered into this
          Agreement in reliance upon the Warranties and has been induced by them
          to enter into this Agreement.

12.4      Any Agreed Claim shall first be satisfied from the Escrow Fund and the
          Vendors shall in accordance with the Escrow Agreement, on demand by
          the Purchaser, authorise the Escrow Agent to transfer to the Purchaser
          that amount of Escrow Shares (ignoring fractional entitlements) valued
          at the last sale price on the NASDAQ National Market on the date prior
          to such transfer or cash held by the Escrow Agent (at the election of
          the Purchaser) to satisfy such claim in accordance with clause 12.6,
          but if the Escrow Fund is not sufficient to cover the Agreed Claim,
          the Vendors shall be liable to pay the balance of such Agreed Claim in
          cash. In any event, any Agreed Claim shall be paid out as promptly as
          practicable but in no event more than 5 days following the Agreed
          Claim Date (as defined in clause 12.5.1.2).

12.5      The maximum liability of each Vendor in the event of an Agreed Claim
          is the following:

12.5.1.1       the sum total of the amounts for the Cash Component, Shares
               Component and (if payable or paid) the Earnout Component
               applicable to the relevant Vendor as set out Schedule 1A (or
               Schedule 8 in the case of the Earnout Component); or, if lower,

12.5.1.2       the amount of the realised proceeds actually received by the
               relevant Vendor in cash and from the sale of New OpenTV Shares
               issued to the Vendor pursuant to this Agreement ("Prior Realised
               Proceeds") prior to the date when the Notified Claim becomes an
               Agreed Claim ("Agreed Claim Date") and if the Vendor has not sold
               all such New OpenTV Shares on or before the Agreed Claim Date,
               the aggregate of

                                      40
<PAGE>

                    the Prior Realised Proceeds and the amount of the value of
                    the remaining New OpenTV Shares not sold by such Vendor at
                    the last sale price on the NASDAQ National Market on the
                    Agreed Claim Date, in either such case net of taxes paid or
                    payable PROVIDED THAT should the Vendor be able, as a
                    consequence of the liability to pay an Agreed Claim, to
                    reclaim taxes paid or to reduce the amount of taxes payable,
                    the Vendor's liability shall not be reduced to such extent
                    and the Vendor shall take all relevant steps in good faith
                    to reclaim such taxes or to reduce his or its liability to
                    repay taxes.

12.6      In the event that the Warranties are breached, the amount of the
          Vendors' liability shall be calculated as:

12.6.1         the amount necessary to put the Purchaser, the Company and each
               of the Subsidiaries into the position which would have existed if
               the Warranties had not been broken or (as the case may be) had
               been true and not misleading or otherwise hold harmless and
               indemnify the Company, the Purchaser and each of the Subsidiaries
               for any losses, claims, damages or other costs and expenses
               arising out of or from such broken, untrue or misleading
               Warranty; and

12.6.2         all costs and expenses incurred by the Purchaser, the Company and
               each member of the Group as a result of such breach and any costs
               (including legal costs on a solicitor and own client basis),
               expenses or other liabilities which any of them may incur either
               before or after the commencement of any action in connection with
               (i) any legal proceedings in which the Purchaser claims that any
               of the Warranties has been broken or is untrue or misleading and
               in which judgment is given for the Purchaser or (ii) the
               enforcement of any settlement of, or judgment in respect of, such
               claim,

          PROVIDED THAT notwithstanding the foregoing, and subject to the
          following provisions of this clause 12.6, the Purchaser may not
          receive any portion of the Escrow Fund or any other payment for breach
          of the Warranties unless and until an aggregate amount in excess of
          (Pounds)500,000 on account of indemnification, damages, costs or
          losses is payable under this clause 12.6, in which case the Purchaser
          shall be
                                      41
<PAGE>

          entitled to claim for and to receive the full amount of such
          indemnification, damages, costs or losses or the like without
          deduction. In determining the amount of any such indemnification,
          damages, costs or losses or the like which is payable, the whole of
          such amount shall be payable, and not just the part in excess of
          (Pounds)500,000. The limitation of (Pounds)500,000 contained in this
          clause does not apply in the case of a breach of the Tax Warranties or
          Warranties 4.1, 4.2, 4.6, 15.1, 15.2 and 15.3.

12.7      Each of the Warranties shall be separate and independent and, save as
          expressly provided to the contrary, shall not be limited by reference
          to or inference from any other Warranty or any other term of this
          Agreement.

12.8      Where any statement in the Warranties or any confirmation or
          certificate given by any of the Vendors hereunder or pursuant hereto
          is qualified by the expression "so far as the Vendors are aware" or
          "to the best of the Vendors' knowledge and belief" or any similar
          expression, that statement shall be deemed to include an additional
          statement that it has been made after due and careful enquiry.

12.9      Each of the Vendors hereby agrees with the Purchaser (for itself and
          as trustee for the Company and each of the Subsidiaries) to waive any
          rights which he may have in respect of any misrepresentation or
          inaccuracy in, or omission from, any information or advice supplied or
          given by the Company or its Subsidiaries or its or their officers,
          employees or advisers in connection with the giving of the Warranties
          and the preparation of the Disclosure Letter.

12.10     Each of the Vendors hereby agrees to disclose promptly to the
          Purchaser in writing as soon as reasonably practicable upon becoming
          aware of the same, any matter, event or circumstance (including any
          omission to act) which may arise or become known to it after the date
          of this Agreement and before Completion which:-

12.10.1        constitutes a breach of or is inconsistent with any of the
               Warranties in any material respect; or

12.10.2        is, or is likely to become, a Material Adverse Event.

                                      42
<PAGE>

12.11  In the event of it becoming apparent on or before Completion that the
       Vendors are in material breach of any of the Warranties or any other term
       of this Agreement the Purchaser may (without any liability on its part)
       rescind this Agreement by notice in writing to the Vendors' Solicitors in
       which case the Purchaser's rights shall be limited as provided in clause
       19.1.1.

12.12  The benefit of the Warranties (subject to the limitations contained in
       this Agreement) may be assigned in whole or in part and without
       restriction by the person for the time being entitled thereto provided
       that the Purchaser provides notice to the Vendors thereof (but no such
       notice is required if the Warranties are assigned to a direct or indirect
       subsidiary of the Purchaser). Any assignee is bound by the provisions of
       this clause 12.

12.12.1   The liabilities of the Vendors under the Warranties shall cease after
          the date one year after the Completion Date in relation to all
          Warranties (other than the Tax Warranties where the liabilities of the
          Vendors shall cease seven years after the Completion Date or
          Warranties 4.1, 4.2, 4.6 and 15.1, 15.2 and 15.3 where there shall be
          no time limit), except (whether in relation to the Tax Warranties or
          any other Warranties) in respect of matters which have been the
          subject of a written claim made before such date by the Purchaser or
          the Purchaser's Solicitors to any of the Vendors or the Vendors'
          Solicitors unless in each case the relevant claim or claims has arisen
          by reason of fraud, wilful concealment, dishonesty or deliberate non-
          disclosure on the part of any of the Vendors or Mr. Bustin or on the
          part of any officer or representative of or of any Vendor which is not
          a natural person prior to the date of this Agreement, in which event
          there shall be no limit on the amount recoverable by the Purchaser
          from the Vendors or Mr. Bustin in respect of such claim or claims or
          the time period within which such claims may be brought.

12.13  If any sum payable by the Vendors under this clause 12 shall be subject
       to Tax (whether by way of deduction or withholding or direct assessment
       of the person entitled thereto) such payment shall be increased by such
       an amount as shall ensure that after deduction, withholding or payment of
       such Tax the recipient shall have received a net amount equal to the
       payment otherwise required hereby to be made

                                      43
<PAGE>

       provided that this clause shall not apply (a) if the payee is not the
       original party to this Agreement and the deduction, withholding or
       payment required to be made arises solely by reason of the change in the
       identity of the payee or (b) to interest under clause 13.9 (default
       interest).

12.14  The Purchaser shall use reasonable endeavours to obtain, and if the
       Purchaser receives, a credit for or refund of any Tax payable by it by
       reason of any deduction or withholding for or on account of Tax then, to
       the extent that the Purchaser is satisfied (acting reasonably and in good
       faith) it can do so without prejudice to the retention or any credit,
       refund or similar benefit it receives, it shall reimburse to the Vendors
       such part of any additional amounts paid by the Vendors under clause
       12.15 as the Purchaser certifies to the Vendors will leave it (after such
       reimbursement) in no better and no worse position than it would have been
       if the Vendors had not been required to make such deduction or
       withholding.

12.15  The Vendors shall have no liability in respect of a claim under the
       Warranties (other than the Tax Warranties) for breach of Warranty to the
       extent that it occurs or is increased as a result of:

12.15.1   legislation not in force at the date of this Agreement including,
          without limitation, any legislation taking effect retrospectively
          after the Completion Date;

12.15.2   any change after the Completion Date in generally accepted accounting
          practices;

12.15.3   a voluntary act, omission, transaction or arrangement by a member of
          the Purchaser or its subsidiaries (other than the Group) or their
          respective employees, officers or agents at any time or by the Company
          or its employees, officers or agents after Completion, in each case
          where the act is outside the normal course of the Business; or

12.15.4   a breach of this Agreement by the Purchaser.

                                      44
<PAGE>

12.16  The Vendors shall have no liability in respect of a claim for breach of
       Warranty to the extent that:

12.16.1   the Purchaser or its subsidiaries actually recovers such liability
          from an insurer or other third party;

12.16.2   a provision relating to the circumstance to which the claim relates
          has been made in the Accounts or Management Accounts or details of the
          same are set out fairly in the Disclosure Letter;

12.16.3   the breach in respect of which the claim is made is remedied by the
          Vendors within 30 days of the date on which the Vendors are given
          written notice by the Purchaser of the circumstances to which the
          claim relates;

12.16.4   such breach is primarily attributable to the Vendors or the Company
          having done (or omitted to do) something before Completion with the
          Purchaser's prior written consent;

12.16.5   the matter is fairly disclosed in the Disclosure Letter or the
          supplemental Disclosure Letter in the agreed terms described in Clause
          6.2.1.6; and

12.16.6   the circumstances of such breach have already been the subject of a
          payment pursuant to clause 10.6.

12.17  The Purchaser represents, warrants and undertakes to and with the Vendors
       that each of the statements set out in Schedule 6 is now true and
       accurate (the "Purchaser Warranties").

12.18  The liability of the Purchaser under the Purchaser Warranties to each
       Vendor who has a claim against the Purchaser for breach of a Purchaser
       Warranty shall be limited to the value of the Consideration due to that
       Vendor as calculated in accordance with clause 3 and Schedule 1C.

12.19  The Purchaser may at its sole option satisfy any Purchaser Warranty claim
       by cash in Pounds Sterling or with New OpenTV Shares valued at
       (Pounds)10.43 (or such other Pounds

                                      45
<PAGE>

       Sterling amount as the Purchaser's Accountants determine to be fair and
       reasonable in the event of any consolidation, sub-division, stock split
       or reclassification or reduction of the share capital of the Purchaser or
       any rights issue, taking place after the date of Completion) per share.
       Any payment or delivery of an OpenTV Share under this clause shall be
       made by the delivery of a certificate therefor in the name of the
       relevant Vendor and delivered to the Vendors' Solicitors, whose receipt
       shall be an absolute discharge therefor and the Purchaser shall not be
       concerned to see the distribution of the moneys represented thereby.

12.20  The Purchaser acknowledges that, in relation to any Notified Claim, it
       shall and shall procure that the Company shall comply with its duty at
       law to mitigate its losses.

               before the Completion Date was subject (in which case the
               disposal shall, for the purposes of this Agreement, be treated as
               having been made before the

                                      46

               no provision has been made in preparing the Accounts, of any
               relief which would (were it not for the said loss, reduction or
               setting off) have been available to the Company or any of the
               Subsidiaries and which has been taken into account in computing
               (and so eliminating or reducing) any provision

                                      47
<PAGE>

               for deferred Tax which appears (or which but for such relief
               would have appeared) in the Accounts;

13.1.4.2       the loss or reduction in the amount of, or the setting off
               against any Tax liability for which no provision has been made in
               preparing the Accounts, of a right to repayment of Tax which has
               been treated as an asset of the Company or any of the
               Subsidiaries in preparing the Accounts; and

13.1.4.3       the loss or reduction in the amount of, or the setting off
               against income, profits or gains earned, accrued or received on
               or before Completion, or against any Tax liability of any relief
               which is not available before Completion but which arises in
               respect of an event occurring after Completion in circumstances
               where, but for such loss, reduction or setting off, the Company
               or any of the Subsidiaries would have had a Tax liability in
               respect of which the Purchaser would have been able to make a
               claim under this clause 13;

          and in such a case the amount of Tax which could otherwise be saved or
          relieved, by the relief so lost, reduced or set off or the amount of
          repayment which would otherwise have been obtained shall be treated as
          the amount of a Tax liability which has arisen;

13.1.5    reference to a payment in respect of Tax includes (without limitation)
          a payment for the surrender of losses or other amounts by way of group
          relief (within the meaning of Section 402 of the Taxes Act) or for the
          surrender of advance corporation tax or for the transfer of any other
          relief, a repayment of any such payment and a payment by way of
          reimbursement, recharge, indemnity or damages.

13.2   Subject as hereinafter provided, the Vendors hereby covenant with and
       undertake to pay to the Purchaser (for itself and as trustee for its
       successors in title) a sum equal to the amount of:

                                      48
<PAGE>

13.2.1    any Tax liability of the Company or any of the Subsidiaries resulting
          from or by reference to any income, profits or gains earned accrued or
          received on or before the Completion Date or any event on or before
          the Completion Date whether or not such Tax is chargeable against or
          attributable to any other person; and

13.2.2    any Tax liability of any member of the Group that arises after
          Completion as a result of an act, omission or transaction by any of
          the Vendors or any person connected with them (other than any member
          of the Group) and which Tax liability falls upon the relevant member
          of the Group as a result of its having been in the same group for Tax
          purposes as that person at any time before Completion; and

13.2.3    all reasonable costs and expenses which are properly incurred by the
          Purchaser or any member of the Group in connection with any Tax
          liability for which the Vendors are liable under this clause 13 (or
          would have been liable but for any action taken by or on behalf of the
          Purchaser in relation to which the costs and expenses have been
          incurred) or any action taken in accordance with clauses 13.4, 13.11
          or 13.19 (including, without prejudice to the generality of the
          foregoing, all legal and other professional fees and disbursements).

13.3   The covenants contained in clause 13.2 do not apply to any liability and
       the Vendors shall not be liable for a breach of a Tax Warranty:

13.3.1    to the extent that provision or reserve in respect thereof has been
          made in the Accounts or to the extent that payment or discharge of
          such liability has been taken into account therein;

13.3.2    in respect of which provision or reserve has been made in the
          Accounts, which is insufficient only by reason of any increase in
          rates of Tax made after the Completion Date with retrospective effect;

                                      49
<PAGE>

13.3.3    to the extent the Tax liability arises as a result of or by reference
          to any income profits or gains received by the Company or any of the
          Subsidiaries, or as a result of an event or events (whether combined
          with other events or not) actually occurring, after the Accounting
          Date but on or before the Completion Date in each case in the ordinary
          course of business of the Company or any of the Subsidiaries;

13.3.4    to the extent that the Tax liability arises as a result of a change in
          legislation or case law or published practice of a Tax authority
          announced after the Completion Date with retrospective effect;

13.3.5    to the extent that the Tax liability consists of penalties or interest
          on Tax resulting from a failure by the Company or a Subsidiary to pay
          Tax to a Tax authority promptly after the Vendors have satisfied such
          liability to the Purchaser as it has in respect of that Tax under this
          clause;

13.3.6    to the extent that the Tax liability would not have arisen or is
          increased by the Purchaser, the Company or any of the Subsidiaries
          failing to act in accordance with clauses 13.4, 13.5, 13.13 and 13.19
          of this Agreement;

13.3.7    to the extent that the Tax liability would not have arisen but for a
          change:

13.3.7.1       announced after Completion in applicable generally accepted
               accounting practices or standards; or

13.3.7.2       a change after Completion which affects the way in which
               statutory accounts of the Company or the Subsidiaries are
               prepared, presented or compiled (except where such change is
               necessary to ensure compliance with generally accepted accounting
               principles as a result of non-compliance by the Company or the
               Subsidiaries prior to Completion);

13.3.8    to the extent that the liability would not have arisen but for any
          relief (other than a relief referred to in clause 13.1.4.1 or clause
          13.1.4.3) or right to

                                      50
<PAGE>

          repayment of Tax (other than a right to repayment referred to in
          clause 13.1.4.2) available to the Company or a Subsidiary at
          Completion being utilised in respect of Tax resulting from any event
          occurring or entered into after the Completion Date or resulting from
          or calculated by reference to any income, profits or gains earned,
          accrued or received deemed to have been earned, received or accrued
          after the Completion Date;

13.3.9    which would not have arisen but for any voluntary act, transaction or
          arrangement of the Purchaser or its employees or agents or any person
          connected with the Purchaser at any time or of the Company or its
          employees or agents or any person connected with the Company
          (including the Subsidiaries assigns and successors in title) carried
          out, or occurring after the Completion Date (other than an act,
          transaction or arrangement (i) inside the ordinary course of business
          or (ii) pursuant to an obligation entered on or before Completion) and
          which the Purchaser knew or ought reasonably to have known would give
          rise to the liability in question; or

13.3.10   to the extent that the Tax liability is, or can be, reduced, mitigated
          or deferred by reliefs (other than a relief referred to in clause
          13.1.4) available to the Company or the Subsidiaries at Completion
          except for any reliefs which are taken into account in the Accounts in
          computing (and so eliminating or reducing) any provision for deferred
          Tax;

13.3.11   to the extent that the Tax liability arises as a result of the
          surrender of the Options and has been a deduction used in calculating
          the Consideration pursuant to Schedule 1C.

13.4   If the Purchaser shall become aware of any assessment, notice, demand or
       other document issued or action taken by or on behalf of any person,
       authority or body from which it appears that the Company or any of the
       Subsidiaries has or may have a liability in respect of which a claim
       could be made under this clause, it shall within 14 days give written
       notice thereof to the Vendors and shall (if the Vendors shall indemnify
       and secure the Purchaser and the Company and the Subsidiaries as
       applicable to the Purchaser's reasonable satisfaction against any
       liabilities, costs,

                                      51
<PAGE>

       damages or expenses which may be incurred thereby) (a) take such action
       and procure that the Company and/or the relevant Subsidiary shall take
       such action as the Vendors may reasonably request to dispute, resist or
       compromise the liability; (b) ensure, at the request in writing of the
       Vendors, that all reasonable steps are taken to place the Vendors in a
       position to dispute any claim on behalf of the Company or a Subsidiary;
       and (c) render, or cause to be rendered, to the Vendors, at the Vendors
       expense, all reasonable assistance the Vendors may require in disputing
       the claim;

13.5   If the Vendors take conduct of a claim for Tax under clause 13.4:

13.5.1    subject to the prior written approval of the Purchaser (not to be
          unreasonably withheld or delayed), the Vendors are entitled, on behalf
          of the Company or any of the Subsidiaries, to instruct solicitors or
          other professional advisers, to act on behalf of the Company or any of
          the Subsidiaries;

13.5.2    the Vendors shall ensure that no material correspondence, pleading or
          other document in connection with the claim for Tax is sent,
          transmitted, issued, entered into or in any way published by the
          Vendors or its advisers without the prior written approval of the
          Purchaser (not to be unreasonably withheld or delayed), and only after
          incorporating all the Purchaser's reasonable comments;

13.5.3    the Vendors shall keep the Purchaser fully informed of all relevant
          matters, dates and places of relevant meetings with the Tax authority
          (which a representative of the Purchaser is entitled to attend) and
          shall promptly forward, or procure to be forwarded, to the Purchaser
          copies of relevant correspondence and other written communications and
          notes of relevant telephone conversations; and

13.5.4    the Vendors shall make no settlement or admission of liability,
          agreement or compromise of the subject matter of any claim for Tax,
          and shall not agree any matter in the conduct of any claim for Tax
          without the prior written approval of the Purchaser (not to be
          unreasonably withheld or delayed).

                                      51
<PAGE>

13.6   If any dispute arises between the Purchaser and the Vendors as to whether
       the claim for Tax should be settled in full, or contested in whole or in
       part, the dispute shall be referred to the determination of a senior tax
       counsel, of at least ten years' standing (or his equivalent in any
       foreign jurisdiction), appointed by agreement between the Purchaser and
       the Vendors, or (if they do not agree) on the application by either party
       to the president for the time being of the Law Society, whose
       determination shall be final. The counsel shall be asked to advise
       whether, in his opinion, contesting the claim for Tax has a reasonable
       chance of success. The claim will only be contested if counsel advises
       that it has a reasonable chance of success. The parties shall pay the
       costs of the dispute in such proportions as counsel determines is fair
       and reasonable.

13.7   The liability of the Vendors under this clause shall cease seven years
       after the Completion Date except in respect of matters which have been
       the subject of a written claim made within the said period by the
       Purchaser to any of the Vendors or the Vendors' Solicitors unless the
       claim in question has arisen by reason of fraudulent or negligent conduct
       on the part of any of the Vendors or, prior to the Completion Date, on
       the part of any member of the Group or on the part of any officer or
       representative of any member of the Group in which event there shall be
       no contractual limit on the time period within which such claim may be
       brought. The liability of the Vendors under this clause 13 shall not
       exceed the amount of the Consideration paid to the Vendors.

13.8   The due date for the making of payments under this clause 13 shall be the
       later of the date five business days after the date on which the
       Purchaser serves notice on the Vendors setting out details and the amount
       of the claim and requesting payment and:

13.8.1    where the payment relates to a liability of the Company or any of the
          Subsidiaries to make an actual payment of or in respect of Tax, the
          date which is five business days before the date on which such actual
          payment is due to be made to the relevant authority;

13.8.2    where the payment relates to a matter falling within clause 13.1.4.1,
          the date five business days before the date on which Tax which would
          otherwise have been saved comes due to the relevant authority;

                                      53
<PAGE>

13.8.3    where the payment relates to a matter falling within clause 13.1.4.3,
          the date five business days before the first date on which the Company
          or the Subsidiary is due to make a payment of Tax which it would not
          have had to make but for the loss, reduction or set off;

13.8.4    where the payment relates to a matter falling within clause 13.1.4.2
          the date on which the repayment of Tax would otherwise have been due
          to be made; and

13.8.5    in the case of costs and expenses within clause 13.2.4 the date which
          is five business days before the date on which payment for such costs
          and expenses is due to be made by the Purchaser, Company or Subsidiary
          (as applicable).

13.9   If any payment due to be made by the Vendors under this clause is not
       made on the due date for payment thereof the same shall carry interest
       from such due date of payment until actual payment at the rate of 2 per
       cent above the base rate from time to time of Barclays Bank PLC,
       compounded on the last days of March, June, September and December in
       each year provided that where a payment falls due in respect of a Tax
       liability, the Purchaser shall not be entitled to interest under this
       clause in respect of any period to the extent that the payment due from
       the Vendors in respect of the Tax liability includes interest for late
       payment of Tax for the same period.

13.10  If any sum payable by the Vendors under this clause 13 shall be subject
       to Tax (whether by way of deduction or withholding or direct assessment
       of the person entitled thereto) such payment shall be increased by such
       an amount as shall ensure that after deduction, withholding or payment of
       such Tax the recipient shall have received a net amount equal to the
       payment otherwise required hereby to be made provided that this clause
       shall not apply (a) if the payee is not the original party to this
       agreement and the deduction, withholding or payment required to be made
       arises solely by reason of the change in the identity of the payee or (b)
       to interest under clause 13.9 (default interest).

13.11  The Purchaser shall use reasonable endeavours to obtain, and if the
       Purchaser receives, a credit for or refund of any Tax payable by it by
       reason of any deduction or

                                      54
<PAGE>

       withholding for or on account of Tax then, to the extent that the
       Purchaser is satisfied (acting reasonably and in good faith) it can do so
       without prejudice to the retention or any credit, refund or similar
       benefit it receives, it shall reimburse to the Vendors such part of any
       additional amounts paid by the Vendors under clause 13.10 as the
       Purchaser certifies to the Vendors will leave it (after such
       reimbursement) in no better and no worse position than it would have been
       if the Vendors had not been required to make such deduction or
       withholding.

13.12  If the Vendors have paid or are due to make payment to the Purchaser in
       respect of a claim under this clause and the Company or a Subsidiary has
       received a payment or obtained a credit or set-off from any person in
       respect of the payment or has a right of reimbursement against any person
       in respect of the Tax liability giving rise to the claim, the Purchaser
       shall notify the Vendors in writing of such payment, credit, set off or
       right of reimbursement.

13.13  In the case of a right to reimbursement under clause 13.12, the Purchaser
       shall, if requested by the Vendors, take reasonable steps to procure that
       the Company or the relevant Subsidiary enforces the right, provided that
       the Vendors indemnify and secure the Purchaser, the Company and the
       relevant Subsidiary (to the Purchaser's reasonable satisfaction) against
       all liabilities, damages, costs and expenses which may be incurred by any
       of them.

13.14  The "Relevant Amount" for the purposes of clause 13.17, arising under
       clause 13.12 or 13.13, is the amount of any payment, credit or set-off
       received or sum recovered by the Company under clause 13.12 or 13.13,
       less an amount equal to all reasonable costs and expenses, incurred by
       the Purchaser, the Company or Subsidiary in respect of or in consequence
       of the payment, credit, set-off or reimbursement.

13.15  This clause will apply if the Vendors have paid an amount to the
       Purchaser in respect of a claim under this clause and the Company's or
       Subsidiaries' auditors certify (at the request and expense of the
       Vendors) that the claim has given rise to a relief available to the
       Company or a Subsidiary which would not have arisen but for the payment
       by the Vendors ("Specified Saving").

                                      55
<PAGE>

13.16 The "Relevant Amount" for the purposes of clause 13.17, arising under
      clause 13.15, shall be the amount of the Specified Saving, less an amount
      equal to all reasonable costs and expenses incurred by the Purchaser, the
      Company or Subsidiary in respect of or in consequence of the Specified
      Saving.

13.17 The Purchaser shall credit the Vendors for any Relevant Amount as follows:

13.17.1   first against any outstanding claim under this clause;

13.17.2   then, to the extent only of any balance, by reimbursement to the
          Vendors of any sums paid by the Vendors in respect of a claim under
          this clause, within ten business days of receipt by the Company of the
          Relevant Amount; and

13.17.3   then, to the extent only of any balance, as a credit against any
          future claims under this clause 13.

13.18 If the Company's or a Subsidiary's auditors certify (at the request and
      expense of the Vendors) that a provision for Tax in the Accounts has
      proved to be an over provision, then the amount of the over provision
      shall be set off against any outstanding or future claims under this
      clause 13.

13.19 To the extent that the Purchaser or its Associates suffer no adverse
      financial consequences pursuant to the provisions of this clause, the
      Purchaser shall use all reasonable endeavours to procure that the Company
      and the Subsidiaries use all reliefs (other than a relief referred to in
      clause 13.1.4) available to them and makes all elections, so as to reduce
      or eliminate the liability of the Vendors under this clause.

14.   Covenant from the Purchaser
      ---------------------------

14.1  The Purchaser shall pay to the Vendors an amount equal to any liability to
      Tax of the Vendors arising pursuant to:

14.1.1    the provisions of section 189 or 191 TCGA by reason of the disposal by
          the Company or a Subsidiary of any asset or of any interest in or
          right over any

                                      56

          asset or the Company or a Subsidiary ceasing to be resident in the
          United Kingdom for any Tax purpose at any time after Completion;

14.1.2    the provisions of section 767A or 767AA Taxes Act but only in
          circumstances where the Tax is directly or primarily attributable to
          the Company or a Subsidiary and the Tax arises (i) in respect of
          income, profits or gains earned accrued or received by the Company or
          a Subsidiary in respect of any period after Completion or in the
          ordinary course of business since the Accounts Date or (ii) as a
          result of the failure by the Purchaser, the Company or a Subsidiary to
          apply an amount paid by the Vendors to the Purchaser under this clause
          to discharge a Tax liability to which the Tax relates or (iii) as a
          result of the failure by the Purchaser, the Company or a Subsidiary to
          apply an amount provided for in respect of such liability in the
          Accounts; and

14.1.3    all reasonable costs and expenses properly incurred by the Vendors in
          connection with the liability to Tax

14.2  The Purchaser shall pay any amounts due to the Vendors under this Clause
      on the later of:

14.2.1    five business days before the last date on which the Tax could be paid
          by the Vendors to the relevant authority in order to prevent a
          liability to interest or a fine, charge, penalty or surcharge from
          arising in respect thereof; and

14.2.2    five business days after the date on which the Vendors serve notice on
          the Purchaser setting out details and the amount of the claim and
          requesting payment.

14.3  The Vendors shall give all such assistance and provide such information
      (at the cost of the Purchaser) as the Purchaser shall reasonably request
      from time to time for the purpose of enabling the Purchaser or any member
      of the Group to make returns and provide information as required to any
      Tax authority and to negotiate any liability to Tax.

     this Agreement including information relating to the provisions of this
     Agreement, the negotiations leading up to this Agreement, the subject
     matter of this Agreement or, in the case of the Vendors or Mr. Bustin only,
     the business or affairs of the Purchaser or any member of  the Purchaser's
     Group (post Completion) or the business and affairs of the Company (this
     obligation shall not apply to the Purchaser post-Completion), and subject
     to the provisions of clause 17.2 that they will not at any time hereafter

          apply to and are observed in relation to, the use or disclosure by
          such professional adviser of the information provided to him).

17.3 The restrictions contained in this clause 17 shall not apply in respect of
     any information which was in the public domain before it was furnished to

18.  Guarantee and Indemnity by Mr Bustin
     ------------------------------------

18.1 In consideration of the Purchaser entering into this Agreement Mr Bustin
     hereby unconditionally and irrevocably guarantees to the Purchaser the due
     and punctual performance and observance by M&TG of all its respective
     obligations, commitments, undertakings, warranties, indemnities and
     covenants under or pursuant to, and subject to the limitations contained
     in, this Agreement and agrees to indemnify the Purchaser against all
     losses, damages, costs and expenses (including legal costs and expenses)
     which the Purchaser may suffer through or arising from any breach by M&TG
     of such obligations, commitments, warranties, undertakings, indemnities or
     covenants.  The liability of Mr Bustin as aforesaid shall not be released
     or diminished by any arrangements or alterations of terms (whether of this
     Agreement or otherwise) or any forbearance, neglect or delay in seeking
     performance of the obligations hereby imposed or any granting of time for
     such performance.

18.2 If and whenever M&TG defaults for any reason whatsoever in the performance
     of any obligation or liability undertaken or expressed to be undertaken by
     it under or pursuant to this Agreement, Mr Bustin shall, subject to any
     limitation applicable to

                                      59
<PAGE>

     M&TG pursuant to this Agreement, forthwith upon demand unconditionally
     perform (or procure performance of) and satisfy (or procure the
     satisfaction of) the obligation or liability in regard to which such
     default has been made in the manner prescribed by this Agreement and so
     that the same benefits shall be conferred on the Purchaser, the Company or
     the Subsidiaries as it would have received if such obligation or liability
     had been duly performed and satisfied by M&TG. Mr Bustin hereby waives any
     rights which it may have to require the Purchaser to proceed first against
     or claim payment from M&TG to the intent that as between the Purchaser and
     Mr Bustin the latter shall be liable as principal debtor as if it had
     entered into all undertakings, agreements and other obligations jointly and
     severally with the other Vendors.

18.3 This guarantee and indemnity is to be a continuing security to the
     Purchaser for all obligations, commitments, warranties, undertakings,
     indemnities and covenants on the part of M&TG under or pursuant to this
     Agreement notwithstanding any settlement of account or other matter or
     thing whatsoever.

18.4 This guarantee and indemnity is in addition to and without prejudice to and
     not in substitution for any rights or security which the Purchaser may now
     or hereafter have or hold for the performance and observance of the
     obligations, commitments, undertakings, covenants, indemnities and
     warranties of M&TG under or in connection with this Agreement.

18.5 In the event of Mr Bustin having taken or taking any security from M&TG in
     connection with this guarantee and indemnity, Mr Bustin hereby undertakes
     to hold the same in trust for the Purchaser pending discharge in full of
     all Mr Bustin's obligations under this Agreement.  Mr Bustin shall not,
     after any claim has been made pursuant to this clause 18, claim from M&TG
     any sums which may be owing to him from M&TG or have the benefit of any
     set-off or counter-claim or proof against or dividend, composition or
     payment by M&TG until all sums owing to the Purchaser in respect hereof
     shall have been paid in full.

18.6 As a separate and independent stipulation, Mr Bustin agrees that any
     obligation expressed to be undertaken by M&TG under this Agreement
     (including, without limitation, any moneys expressed to be payable under
     this Agreement) which may not

                                      60
<PAGE>

     be enforceable against or recoverable from M&TG by reason of any legal
     limitation, disability or incapacity of any of them or any other fact or
     circumstance shall nevertheless be enforceable against or recoverable from
     Mr Bustin as though the same had been incurred by Mr Bustin and Mr Bustin
     were sole or principal obligor in respect thereof and shall be performed or
     paid by Mr Bustin on demand.

19.  Costs
     -----

19.1 Each party to this Agreement shall pay its own costs of and incidental to
     this Agreement and the sale and purchase hereby agreed to be made provided
     that:

19.1.1    if the Purchaser shall lawfully exercise its right not to proceed with
          the purchase of the Sale Shares pursuant to this Agreement, the Vendor
          or Vendors whose breach has entitled the Purchaser to rescind this
          Agreement shall, in proportion to their respective entitlements to the
          Consideration, indemnify the Purchaser against all reasonable fees,
          expenses and disbursements incurred by the Purchaser in the
          preparation and negotiation of this Agreement and the Vendors shall
          have no other liabilities to the Purchaser pursuant to this Agreement.

19.1.2    if the Vendors (or any one of them, and the exercise of the right by
          one Vendor shall operate as the exercise of the right by all Vendors)
          shall lawfully exercise their, his or its right not to proceed with
          the sale of the Sale Shares pursuant to this Agreement, the Purchaser
          shall indemnify the Vendors against all reasonable fees, expenses and
          disbursements incurred by the Vendors in the preparation and
          negotiation of this Agreement and the Purchaser shall have no other
          liabilities to the Vendors pursuant to this Agreement.

19.2 The Vendors and Mr Bustin confirm that no expense of whatever nature
     relating to the sale of the Sale Shares has been or is to be borne by any
     member of the Group and agree that if any member of the Group in fact has
     paid or pays such amount the Purchaser may in addition to obtaining such
     amount from the Vendors or Mr.  Bustin, obtain any such amount from the
     Escrow Fund to cover any such payments in accordance with clause 9.2.

20.  General
     -------

20.1 Save as expressly provided in clause 20.2 a person who is not a party to
     this Agreement shall not have or acquire any right to enforce any term of
     this Agreement (including but not limited to any right to enforce or have
     the benefit of any exclusion or limitation of liability contained in this
     Agreement).  This clause shall override any other clause in this Agreement,
     which is or may be inconsistent with it.

20.2 This Agreement shall be binding upon and enure for the benefit of the
     estates, personal representatives or successors of the parties.  No party
     shall be entitled to assign the benefit of this Agreement save that the
     Purchaser shall be entitled to assign the benefit of this Agreement in
     whole or in part and without restriction.

20.3 This Agreement (together with any documents referred to herein or executed
     contemporaneously by the parties in connection herewith) constitutes the
     whole agreement between the parties hereto and supersedes any previous
     agreements or arrangements between them (whether written or oral) relating
     to the subject matter hereof; it is expressly declared that no variations
     hereof shall be effective unless made in writing signed by duly authorised
     representatives of the parties.

20.4 Each party waives its rights against the other in respect of warranties and
     representations (whether written or oral) relating to the sale of the Sale
     Shares not expressly set out or referred to in this Agreement, the
     Registration Rights Agreement or the Escrow Agreement.

20.5 Unless and to the extent only expressly provided otherwise:

20.5.1    the Vendors give no promise, warranty, undertaking or representation
          to the Purchaser;

20.5.2    to the extent allowable, all other warranties on the part of the
          parties express or implied by law or otherwise are expressly excluded.

                                      62
<PAGE>

20.6  Nothing in clauses 20.4 and 20.5 limit or exclude liability for fraud or
      wilful misconduct, concealment or recklessness.

20.7  The Purchaser, Mr Bustin and the Vendors acknowledge that they have had
      the benefit of legal advice on the effects of clauses 20.4, 20.5 and 20.6
      and confirm that they consider such clauses to be reasonable in all the
      circumstances of this Agreement.

20.8  All of the provisions of this Agreement shall remain in full force and
      effect notwithstanding Completion (except insofar as they set out
      obligations which have been fully performed at Completion).

20.9  If any provision or part of a provision of this Agreement shall be, or be
      found by any authority or court of competent jurisdiction to be, invalid
      or unenforceable, such invalidity or unenforceability shall not affect the
      other provisions or parts of such provisions of this Agreement, all of
      which shall remain in full force and effect.

20.10 If any liability of one or more but not all of the Vendors or Mr Bustin
      shall be or become illegal, invalid or unenforceable in any respect, such
      circumstance shall not affect or impair the liabilities of the other
      Vendors under this Agreement.

20.11 Any right of rescission conferred upon a party hereby shall, subject to
      clause 19.1 and to the remainder of this clause 20.11, be in addition to
      and without prejudice to all other rights and remedies available to it
      (and, without prejudice to the generality of the foregoing, shall not
      extinguish any right to damages to which the Purchaser may be entitled in
      respect of the breach of this Agreement) and no exercise or failure to
      exercise such a right of rescission shall constitute a waiver by such
      party of any such other right or remedy. No party shall have any right to
      rescind this Agreement after Completion.

20.12 The Purchaser may release or compromise the liability of any of the Vendor
      Mr Bustin hereunder or grant to any Vendor or Mr Bustin time or other
      indulgence without affecting the liability of any other Vendor or Mr
      Bustin (as the case may be) hereunder.

                                      63
<PAGE>

20.13 No failure of the Purchaser to exercise, and no delay or forbearance in
      exercising, any right or remedy in respect of any provision of this
      Agreement shall operate as a waiver of such right or remedy.

20.14 Upon and after Completion the parties shall do and execute or procure to
      be done and executed all such further acts, deeds, documents and things as
      may be necessary to give effect to the terms of this Agreement and to
      place control of the Company and the Subsidiaries in the hands of the
      Purchaser and pending the doing of such acts, deeds, documents and things
      the Vendors and Mr Bustin shall as from Completion hold the legal estate
      in the Sale Shares in trust for the Purchaser.

20.15 This Agreement may be executed in one or more counterparts, and by the
      parties on separate counterparts, but shall not be effective until each
      party has executed at least one counterpart and each such counterpart
      shall constitute an original of this Agreement but all the counterparts
      shall together constitute one and the same instrument.

                 Pro Forma example of the Total Consideration


                       Calculation of the Consideration


Introduction
------------

(a)  The cross-references (annotated (#)) in this Schedule are to the figures on
     pages 76A and 76B of this Agreement.  The references annotated * are the
     variables referred to in clause 3.4.1 of the Agreement which are to be
     reflected in the Adjusted Spreadsheet to be prepared pursuant to that
     clause immediately prior to Completion.

(b)  For the purposes of this calculation each New OpenTV share has a value of
     US$15 and shall be converted into (Pounds)sterling at a rate of US$1.438:
     (Pounds)1.

Consideration
-------------

The Total Consideration shall be calculated as follows:

1.   The (Pounds)Sterling amount equal to employer's NIC payable by the Company
     in relation to the surrender of all the Unapproved Options and 20% of the
     Approved Options under the Option Surrender Agreements (#1*) (and
     calculated in accordance with footnote 1) shall be deducted from the sum
     equal to the aggregate of (Pounds)12,000,000 and the value of 3,451,200 New
     OpenTV Shares in (Pounds)Sterling; the resulting sum being the "Gross
     Consideration" (#2).

2.   The Gross Consideration will be divided in the ratio 3:1 between a "Gross
     Share Component" (#28) and a "Gross Cash Component" (#27) respectively or
     in such ratio as is applied through the Purchaser exercising their right
     under clause 3.3 of the Agreement (*).

3.   The Gross Cash Component then has an amount equal to the sum of the
     following (Pounds) sterling amounts deducted from it:

     (ii)   the amount of the HSBC Loans at their maturity value, being

     (iii)  the amount of the HSBC fee and expenses being (Pounds)1,047,983.34
            (#5);

     the resulting sum then has added back to it (subject to clause 5.4) an

     immediately proceeding Completion (#6*) together with a sum equal to the
     exercise price that would be payable under the Option Schemes by the
     holders of Approved Options over 20% of those options and by the holders of
     Unapproved Options over all their options (#7);

     the resulting figure being the "Net Cash Component" (#8).

4.   The Gross Share Component then (i) has deducted from it the value of 94,550
     New OpenTV Shares calculated at (Pounds)10.43 per share over which options
     will be granted to existing Static Optionholders (#9), and (ii) the sum

     the cash cancellation payment under the Option Surrender Agreements to the
     holders of Approved Options (calculated in accordance with paragraph 5)
     (#12) is then deducted from the Net Cash Component.

     and by the holders of Unapproved Options over all their options (#18) is

     component (#16).

10.  The Vendors shall be entitled to the percentage of the total share
     component and the total cash component in the proportions set out against
     their names in the Excel spreadsheet, the aggregate of which is the
     "Vendors' Total Share and Cash Component" (#19). There shall then be
     deducted from the share component which otherwise would be payable to the
     Vendors a sum equal to 25% of the value of the Vendors' Total Share and
     Cash Component (which deduction constitutes "Z" for the purposes of the
     earn-out calculation in Schedule 8) (#20), the aggregate of the Vendors'
     net entitlement being the "Share Component" (#21) and the "Cash Component"
     (#22) payable in respect of the Sale Shares on Completion, as defined under
     this Agreement.  The balance of the total share component (#23) and of the
     total cash component (#24) shall be payable to the vendors under the Non-
     Principal Share Purchase Agreement each of whom shall be entitled to the
     percentage of the total share component and the total cash component in the
     proportions set out against their names in the Excel spreadsheet.  For the

Footnotes:
---------

1. The Company's liability for NIC will be calculated on the basis of the market
value of OpenTV Shares as quoted on NASDAQ at close of trading on the day prior
to Completion (converted into (Pounds)sterling at the exchange rate quoted by
Barclays Bank plc on that day) and calculated at the rate of 11.9%.

2. The amount recorded in the Company's books of record due to the Purchaser
under the Interim Bridge Loan will be the principal and accrued interest sums up
to close of business on the day prior to Completion less any amount drawn down
for the purposes of the Group's operational costs (not to exceed
(Pounds)560,000) in respect of the period after the date on which the Vendors
demonstrate their ability to satisfy clauses 4.1.5, 4.1.6, 4.1.8, 4.1.10, 4.1.12
and 6.2.1.15 of the Agreement such amount accruing proportionally during the
period between the date of this Agreement and Completion.

3. The value of the cash cancellation payments to Approved Optionholders is
calculated on the basis that 20% of the Approved Options have vested and are
exercisable i.e. the value attached to the fully diluted share capital of the
Company less the exercise price in respect of each Option less PAYE/NIC as paid
on their behalf by the Company.

4. The value of the Open TV share cancellation payments to Unapproved
Optionholders is calculated on the basis that 100% of the Unapproved Options
have vested and would be exercisable i.e. the value attached to the fully
diluted share capital of the Company less the exercise price in respect of each
Option less PAYE/NIC as paid on their behalf by the Company on the basis of a
(Pounds)17.38 per OpenTV Share price (or if less, the closing price of an OpenTV
Share on the NASDAQ National Market on the day prior to Completion converted
into (Pounds) sterling on that day).

5. The value of 80% of the Approved Options is calculated as if 80% of the
Approved Options had vested and had been exercisable i.e. the value attached to
the fully diluted share capital of the Company less the exercise price in
respect of each option.

      howsoever.

      of the Properties, which are of an unusual, or onerous nature or which
      adversely affect the use of the Properties for which they are currently
      used.


6.5   The present use of the Properties is the permitted use for the purposes of
      Town and Country Planning Legislation and the use of each of the
      Properties is permitted by such legislation, is not personal to the
      Company, nor is the use a temporary use, nor subject to onerous or unusual
      conditions adversely affecting the Company's use and enjoyment of the
      Properties and the Properties comply with all statutes, regulations, bye
      laws and other relevant legislation and the Company has not received
      notice of any (and is not aware of any) breach of the Town and Country
      Planning legislation.

6.6   So far as the Vendors are aware, there are no outstanding disputes and
      notices or complaints whatsoever, which affect or might in the future
      affect the use of any of the Properties for the purposes for which they
      are now used.


6.7   So far as the Vendors are aware, no structural or other material defects
      have appeared in respect of or affecting the buildings and structures on

      Properties.

6.8   The replies given by the Vendors' Solicitors in writing to enquiries (if
      any) raised by the Purchaser's Solicitors were when given and remain true
      and accurate in all respects.

6.9   The Company has not at any time assigned, underlet, parted with possession
      or otherwise disposed of any property (including for the avoidance of
      doubt the Properties) in respect of which it has a continuing liability
      (contingent or otherwise) for payment of rent and/or for any other
      liability nor has the Company had any other property vested in it apart
      from the Properties.

6.10  The Company has under its control all the originals of the documents
      referred to in Schedule 4 and all other deeds and documents necessary to
      prove its title to the Properties; where any of the Properties is
      leasehold, the title documents include all necessary consents for the
      grant of the lease of the relevant Property and including all
      reversioners' consents required under the lease of the relevant Property.

6.11  As far as the Vendors are aware and save as disclosed in the leases of the
      Properties, no liberty, right, easement, licence or other arrangement is
      enjoyed or is in the course of being acquired by or against the Properties
      (and none is needed) for obtaining access to any land or for repair of any
      premises or to comply with any fire regulations.

6.12  As far as the Vendors are aware and save as disclosed in the leases of the
      Properties which are in the Disclosure Bundle, each of the Properties has
      the benefit of all rights necessary for the continued present use and
      enjoyment of the same such rights not being capable of withdrawal by any
      person nor liable to be made subject to any charge therefor.

6.13  The Properties are not and will not at Completion be subject to any lien,
      encumbrance or any lease or agreement for lease save as already disclosed
      in this Schedule.

6.13.1    The Leases of the Properties are correctly summarised in the
          particulars thereof set out in Schedule 4 specifying which of such
          leases is a new tenancy for the purposes of the L&T Covenant Act.

6.13.2    In respect of any of the leases of the Properties which are new
          tenancies for the purposes of the L&T Covenants Act no person has made
          a claim for an overriding lease under section 19 of the L&T Covenants
          Act and no person is entitled to make such a claim and no notice has
          been served under section 17 of the L&T Covenants Act which would give
          rise to such entitlement and there have been no excluded assignments
          as referred to in section 11 of the L&T Covenants Act.

6.14  The Company has not received any notice of breach and, to the best of the
      Vendors' knowledge, all covenants, restrictions, stipulations, conditions
      and other terms affecting the Properties have been observed and performed
      and so far as the Vendors are aware, there are no circumstances which
      would entitle or require any landlord under any lease of the Properties or
      other person to exercise any powers of entry and taking possession or
      which would otherwise give rise to restriction or termination of the
      continued possession or occupation of any of the Properties.

6.15  All policies of insurance relating to the Properties effected by the
      Company are current and valid and are not subject to any special or
      unusual terms or restrictions or to the payment of any premium in excess
      of the normal rate for policies of the same kind.

6.16  The Company has inspected all current policies of insurance relating to
      any of the Properties (including fixtures fittings and contents) which
      have been effected by a landlord under the terms of a lease of that
      Property and warrants that they are current and valid and cover the full
      reinstatement value of the relevant Property (including loss of rent cover
      for a minimum of three years or more) and are not subject to any special
      or unusual terms or restrictions or to the payment of any premium in
      excess of the normal rate for policies of the same kind and that the
      policy conforms in all respects with the requirements of the relevant
      lease of the Property and the insurer has waived any rights of subrogation
      it may have against the Company.

6.17  The Company is not the guarantor of or surety for any other party's
      liability (contingent or otherwise) for any obligations under any lease or
      tenancy or under any agreement relating to the assignment of any lease or
      tenancy.

       material respects with all their obligations under all legislation,

      party to any voting trust, agreement or arrangement affecting the exercise
      of the voting rights of the relevant shares, other than as set out in the
      Disclosure Letter. There is no action, proceeding, claim or, to any
      Vendors' knowledge and belief, investigation against any Vendor or any
      Vendor's assets, properties or, as applicable, any of the Vendors'
      respective officers or directors, pending or, to Vendors' knowledge and
      belief, threatened, at law or in equity, or before any court, arbitrator
      or other tribunal, or before any administrative law judge, hearing officer
      or administrative agency relating to or in any other manner impacting upon
      the Sale Shares held by such Vendor.


15.3  The execution, delivery and performance of this Agreement, and the
      consummation of the sale and purchase of the Company Shares and the other
      transactions contemplated by this Agreement do not and will not conflict
      with or result in a violation of the Memorandum or Articles of
      Association, bylaws, partnership agreement or other applicable charter
      document of M&TG, or conflict with, or (with or without notice or lapse of
      time, or both) result in a termination, breach, impairment or violation
      of, or constitute a default or result in the creation or imposition of any
      lien, charge or encumbrance upon any of the Vendor's shares under, (a) any
      instrument, indenture, lease, mortgage or other agreement or contract to
      which the Vendor is a party or to which such Vendor or any of such
      Vendor's assets or properties may be subject or (b) any judgment, writ,
      decree, order, ordinance, statute, rule or regulation applicable to the
      Vendor or the Vendor's assets or properties. The consummation of the
      Purchase and the other transactions contemplated by this Agreement will
      not require the consent of any third person with respect to the rights,
      licenses, franchises, leases or agreements of the Vendor.


15.4  Each Vendor hereby acknowledges that he or it has read this Agreement and
      the other documents to be delivered in connection with the consummation of
      the transactions contemplated hereby and has made an independent
      examination of the transactions contemplated hereby (including the tax
      consequences thereof). Each Vendor acknowledges that he or it has had an
      opportunity to consult with and has relied solely upon the advice, if any,
      of the Vendors' legal counsel, financial advisors, or accountants with
      respect to the transactions contemplated hereby to the extent such Vendor
      has deemed necessary, and has not been advised or directed by the
      Purchaser,

                                      113

        the Company or their respective legal counsel or other advisors in
        respect of any such matters and has not relied on any such parties in
        connection with this Agreement and the transactions contemplated hereby.


15.5    Each Vendor severally, and not jointly, represents that:


15.5.1    None of the New OpenTV Shares have been or will be registered under
          the Securities Act, and such securities, to the extent offered, are
          being offered to such Vendor outside the United States in reliance on
          Regulation S under the Securities Act ("Regulation S");


15.5.2    No Vendor is a US person (as defined in Regulation S) and is not
          acquiring the Shares for the account or benefit of any such US person;


15.5.3    Following Completion and subject to the provisions of clause 8, no
          Vendor will resell the New OpenTV Shares except: (i) pursuant to
          registration of the New OpenTV Shares under the Securities Act, (ii)
          in offshore transactions outside the United States in accordance with
          Rule 903 or 904 of Regulation S, or (iii) pursuant to another
          available exemption from the registration requirements of the
          Securities Act; and such Vendor will not engage in hedging
          transactions with regard to the New OpenTV Shares unless in compliance
          with the Securities Act;

15.5.4    Each Vendor acknowledges and accepts that the Purchaser is required
          pursuant to Regulation S to refuse to register the transfer of any
          Shares in violation of the restrictions stated in paragraph 15.5.3 of
          this Schedule, as the case may be, and any certificate representing
          the Shares may bear a legend containing the restrictions stated in
          such paragraph 15.5.3.

16.     Shareholders' Agreement


16.1    Each of the parties to the current shareholders' agreement amongst the
        holders of the Company's Shares is in compliance with the terms thereof

                                      114
<PAGE>

        are aware, no party to that agreement has threatened or indicated that
        it is likely to breach the provisions of such shareholders' agreement
        which are binding on it.


16.2    No claim has been made by BSB, HSBC or any other holder of Company
        Shares against any member of the Group nor has any member of the Group
        received notice of any such claim and, so far as the Vendors are aware,
        no such claim is pending or threatened and there are no circumstances
        known to the Vendors likely to give rise to any such claim.

                                  SCHEDULE 6


                            Purchaser's Warranties


1.   The Purchaser and each subsidiary of the Purchaser which is a significant
     subsidiary as such term is defined under Rule 1.02 of Regulation S-X
     promulgated under the Exchange Act (collectively, the "Purchaser
     Subsidiaries") has been duly organised and is validly existing and in good
     standing under the laws of its jurisdiction of incorporation or
     organisation, as the case may be, and has the requisite power and authority
     and all necessary governmental approvals to own, lease and operate its
     properties and to carry on its business as it is now being conducted.  The
     Purchaser and each Purchaser Subsidiary is duly qualified or licensed to do
     business, and is in good standing, in each jurisdiction where the character
     of the properties owned, leased or operated by it or the nature of its
     business makes such qualification or licensing necessary, except for such
     failures to be so qualified or licensed and in good standing that,
     individually or in the aggregate, have not resulted and could not
     reasonably be expected to result in a Material Adverse Event for the
     Purchaser.


2.   The copies of the Purchaser's Memorandum of Association and Articles of
     Association, each as amended through the date of this Agreement, that are
     available with the SEC, are current, complete and correct copies of those
     documents.  The Purchaser is not in violation of any of the provisions of
     such Memorandum of Association and Articles of Association.


3.   The authorized capital stock of the Purchaser consists of (i) 500,000,000
     Class A Ordinary Shares, (ii)  200,000,000 Class B Ordinary Shares, and
     (iii)  500,000,000 Preference Shares.  As of 31 December, 2000 34,829,632
     Class A Ordinary Shares, 30,631,746 Class B Ordinary Shares and no
     Preference Shares were issued and outstanding, all of which issued and
     outstanding Shares were validly issued and are fully paid, nonassessable
     and, except as set forth in the Investor's Rights Agreement included as an
     Exhibit to the Purchaser's SEC Reports (as defined in clause 9 below) to
     the extent disclosed in Parent SEC Report, not subject to pre-emptive
     rights.

                                      116
<PAGE>

4.   The New OpenTV Shares, upon issuance on the terms and conditions specified
     in this Agreement (i) will be duly authorised, validly issued, fully paid,
     nonassessable, (ii) will not be subject to pre-emptive rights, and (iii)
     will be free and clear of all security interests, liens, claims, pledges,
     options, rights of first refusal, agreements, charges and other
     encumbrances or any nature whatsoever, other than as specifically
     contemplated by this Agreement or by law.


5.   The Purchaser has all necessary corporate power and authority to execute
     and deliver this Agreement and to perform its obligations under this
     Agreement and to consummate the transactions contemplated by this Agreement
     to be consummated by the Purchaser.  The execution and delivery of this
     Agreement by the Purchaser and the consummation by the Purchaser of such
     transactions have been duly and validly authorised by all necessary
     corporate action and no other corporate proceedings on the part of the
     Purchaser are necessary to authorise this Agreement or to consummate such
     transactions.  This Agreement has been duly authorised and validly executed
     and delivered by the Purchaser and constitutes a legal, valid and binding
     obligation of the Purchaser, enforceable against the Purchaser in
     accordance with its terms.


6.   The execution and delivery of this Agreement by the Purchaser does not, and
     the performance of this Agreement by the Purchaser will not:


6.1  conflict with or violate any provision of the Purchaser's Memorandum of
     Association or Articles of Association or any comparable organisational
     documents of any Purchaser Subsidiary;


6.2  assuming that all relevant consents, approvals, authorisations and other
     actions have been obtained and all relevant filings and obligations have
     been made, conflict with or violate any law applicable to the Purchaser or
     any Purchaser Subsidiary or by which any property or asset of the Purchaser
     or any Purchaser Subsidiary is or may be bound or affected, except for any
     such conflicts or violations that, individually or in the aggregate, have
     not resulted and could not reasonably be expected to result in a Material
     Adverse Event for the Purchaser; or

                                      117
<PAGE>

6.3  result in any breach of or constitute a default (or an event which with or
     without notice or lapse of time or both would become a default) under, or
     give to others any right of termination, amendment, acceleration or
     cancellation of, or result in the creation of a lien on any property or
     asset of the Purchaser or any Purchaser Subsidiary under, any contract to
     which the Purchaser or any Purchaser Subsidiary is a party or by which any
     of them or their assets or properties is or may be bound or affected,
     except for any such breaches, defaults or other occurrences which,
     individually or in the aggregate, have not resulted and could not
     reasonably be expected to result in a Material Adverse Event for the
     Purchaser.


7.   The execution and delivery of this Agreement by the Purchaser does not, and
     the performance of this Agreement by the Purchaser will not, require any
     consent, approval, authorisation or permit of, or filing with or
     notification to, any governmental entity except (i) for applicable
     requirements of the Exchange Act, applicable requirements of the Securities
     Act, applicable requirements of Blue Sky Laws, the rules and regulations of
     the NASDAQ National Market and the Amsterdam Stock Exchange, applicable
     requirements of takeover statutes, applicable notification requirements of
     the anti-trust laws or any other laws, and (ii) where failure to obtain
     such consents, approvals, authorisations or permits, or to make such
     filings or notifications, individually or in the aggregate, have not
     resulted and could not reasonably be expected to result in a Material
     Adverse Event for the Purchaser.


8.   Each of the Purchaser and the Purchaser Subsidiaries is in possession of
     all franchises, grants, authorisations, licenses, permits, easements,
     variances, exceptions, consents, certificates, approvals and orders of any
     governmental entity necessary for the Purchaser or any Purchaser Subsidiary
     to own, lease and operate its properties or to carry on its business as it
     is now being conducted (collectively, the "Purchaser Permits"), except
     where the failure to have, or the suspension or cancellation of, any of the
     Purchaser Permits, individually or in the aggregate, has not resulted and
     could not reasonably be expected to result in a Material Adverse Event for
     the Purchaser, and, as of the date of this Agreement, no such suspension or
     cancellation of any of the Purchaser Permits is pending or, to the
     knowledge of the Purchaser, threatened, except where the failure to have,
     or the suspension or cancellation of, any of the Purchaser Permits,
     individually or in the aggregate, has not resulted and could not

                                      118
<PAGE>

     reasonably be expected to result in a Material Adverse Event for the
     Purchaser. Neither the Purchaser nor any Purchaser Subsidiary is in
     conflict with, or in default or violation of, (i) any law applicable to the
     Purchaser or any Purchaser Subsidiary or by which any property or asset of
     the Purchaser or any Purchaser Subsidiary is or may be bound or affected or
     (ii) any Purchaser Permits, except for any such conflicts, defaults or
     violations that, individually or in the aggregate, have not resulted and
     could not reasonably be expected to result in a Material Adverse Event for
     the Purchaser.


9.   The Purchaser has filed all forms, reports, schedules, statements and other
     documents (including all exhibits, annexes, supplements and amendments to
     such documents) required to be filed by it under the Exchange Act and the
     Securities Act (collectively, including any such documents filed subsequent
     to the date of this Agreement, the "Purchaser SEC Reports").  The Purchaser
     SEC Reports, including any financial statements or schedules included or
     incorporated therein by reference, at the time they were filed, (i)
     complied in all material respects with the requirements of the Exchange Act
     or the Securities Act or both, as the case may be, applicable to those
     Purchaser SEC Reports and (ii) did not contain any untrue statement of a
     material fact or omit to state a material fact required to be stated or
     necessary in order to make the statements made in those Purchaser SEC
     Reports, in the light of the circumstances under which they were made, not
     misleading.  No Purchaser Subsidiary is subject to the periodic reporting
     requirements of the Exchange Act or is otherwise required to file any
     documents with the SEC or any national securities exchange or quotation
     service or comparable governmental entity.


10.  Each of the consolidated balance sheets included in or incorporated by
     reference into the Purchaser SEC Reports (including the related notes and
     schedules) fairly presented, in all material respects, the consolidated
     financial position of the Purchaser as of the dates set forth in those
     consolidated balance sheets.  Each of the consolidated statements of income
     and of cash flows included in or incorporated by reference into the
     Purchaser SEC Reports (including any related notes and schedules) fairly
     presented, in all material respects, the consolidated results of operations
     and cash flows, as the case may be, of the Purchaser for the periods set
     forth in those consolidated statements of income and of cash flows, in each
     case in conformity with US Generally Accepted Accounting Principles
     ("GAAP") consistently applied

                                      119
<PAGE>

     throughout the periods indicated. All of such balance sheets and statements
     complied as to form in all material respects with applicable accounting
     requirements and with the published rules and regulations of the SEC with
     respect thereto; provided, however, that the quarterly and annual profit
     and loss statements contained in those Purchaser SEC Reports made on Form
     6-K and Form 6-K/A that have incorporated the Purchaser's quarterly
     earnings press releases were accounted in accordance with GAAP but
     presented in a format alternative to GAAP presentation.


11.  Except as and to the extent set forth on the consolidated balance sheet of
     the Purchaser as of December 31, 2000, including the related notes, neither
     the Purchaser nor any Purchaser Subsidiary has any liabilities or
     obligations of any nature (whether accrued, absolute, contingent or
     otherwise) that would be required to be reflected on a balance sheet or in
     the related notes prepared in accordance with GAAP, except for liabilities
     or obligations incurred in the ordinary course of business since December
     31, 2000 that, individually or in the aggregate, have not resulted and
     could not reasonably be expected to result in a Material Adverse Event for
     the Purchaser.


12.  Since 31 December, 2000 except as set forth in the Purchaser SEC Reports,
     the Purchaser has conducted its business only in the ordinary course and in
     a manner consistent with past practice and, since such date, there has not
     been any Material Adverse Event for the Purchaser.

                              Earn Out Provisions



1.   Definitions


     Earnout Component           that part of the Consideration which is payable
                                 to the Vendors depending on the levels of
                                 Revenue and Net Income in Q3 and Q4 in
                                 accordance with this Schedule;

     Net Income                  net profits from operations after deduction of

                                 amortization of goodwill;

     Q3                          the period beginning 1 July 2001 and ending on
                                 30 September 2001;

     Q4                          the period beginning 1 October 2001 and ending

                                 for unearned and accrued income.
2.

2.1  The Earnout Component shall be equal to Z multiplied by the Factor, subject
     to a minimum of zero and a maximum of 140% of Z.

     Z = 25% of the value of the Vendors' Total Share and Cash Component as
     calculated pursuant to paragraph 10 of Schedule 1C.


     The Factor = A + B + C + D


     Where:

     A = the greater of (i) zero and (ii) (x) Q3 actual Revenue divided by
             (Pounds)3,200,000 multiplied by (y) 0.185

     B = the greater of (i) zero and (ii) the lesser of (x) 0.285 and (y) (a) Q3
             actual Net Income divided by ((Pounds)319,850) multiplied by (b)
             0.19; PROVIDED,

                                      124

             HOWEVER, that if Q3 actual Net Income is greater than
             ((Pounds)319,850) but less than zero, B shall equal the lesser of
             (i) 0.285 and (ii) (x) 2 minus (y) Q3 actual Net Income divided by
             ((Pounds)319,850)

     C = the greater of (i) zero and (ii) (x) Q4 actual Revenue divided by
             (Pounds)4,200,000 multiplied by (y) 0.31

     D = the greater of (i) zero and (ii) the lesser of (x) 0.4725 and (y) (a)
              Q4 actual Net Income divided by (Pounds)313,230 multiplied by (b)
              0.315

3.


3.1  If the Earnout Component is less than Z then the Vendors shall be entitled
     to that number of New OpenTV Shares as is equal to Z minus Earnout
     Component divided by (Pounds)10.43.


3.2  If the Earnout Component is equal to or greater than Z then the Vendors
     shall be entitled to all of the New OpenTV Shares (at an issue price of
     (Pounds)10.43 per share or such other Pounds Sterling amount as the
     Purchaser's Accountants determine to be reasonable in the event of any
     consolidation, sub-division, stock split or reclassification or reduction
     of the share capital of the Purchaser or any rights issue, taking place
     after the date of this Agreement) equal to Z and shall be paid a cash
     amount equal to the excess in the Earnings  Component over Z.


4.


4.1  The Purchaser shall procure the preparation by the Purchaser's Accountants
     of draft accounts for Q3 and draft certificates as to the Revenue and Net
     Income during Q3 and the delivery of those drafts to the Vendors as soon as
     reasonably practicable but no later than 30 calendar days following the end
     of Q3.


4.2  The accounts for Q3 shall be prepared so as to comply with all legal and
     regulatory requirements applying but otherwise in accordance with the same
     accounting policies, standards, principles, bases and methods as are
     applied by the Purchaser in accordance with US GAAP for the year ended 31
     December 2000.


4.3  The Vendors shall review the drafts delivered by the Purchaser's
     Accountants under paragraph 4.1 and shall instruct the Vendors' Accountants
     to deliver to the Purchaser

                                      125
<PAGE>

     and the Purchaser's Accountants as soon as reasonably practicable but no
     later than 30 calendar days of the delivery of the drafts a report setting
     out any matters of disagreement with the drafts in sufficient detail to
     enable the Purchaser to consider them. In the absence of a report within
     that period, the drafts shall be deemed to be agreed by all parties. All
     the items in the drafts (if no report is delivered within the applicable
     time limit) or (if a report is delivered) all the items which are not
     specified in the report as being subject to disagreement, shall be deemed
     to be agreed by the parties.

4.4  If within 30 calendar days of the delivery to the Purchaser of the report
     referred to in paragraph 4.3 there remains an outstanding dispute with
     respect to the drafts the dispute shall be referred to a firm of chartered
     accountants nominated jointly by the Vendors and the Purchaser or, failing
     nomination within ten business days after request by either the Vendors or
     the Purchaser, nominated at the request of either party by the President of
     the Institute of Chartered Accountants in England and Wales.  The firm
     shall be instructed to prepare as soon as practicable a determination of
     the Revenue and Net Income for Q3.  The firm shall act as experts and not
     as arbitrators and their decision (in the absence of manifest error) shall
     be final and binding on the parties.  Their fees shall be payable by the
     Vendors and the Purchaser in such proportions as the firm determines.


4.5  Each party shall procure that the other party and its or their Accountants
     are afforded reasonable access at reasonable times to the accounting
     records required for the production and review of the drafts.


4.6  The provisions of this paragraph 4 shall apply as well as if Q3 were
     substituted by Q4 throughout sub-paragraphs 4.1, 4.2 and 4.4.


5.   Within ten business days of the Revenue and Net Income for Q4 being
     determined in accordance with the provisions of this Schedule any further
     consideration payable in New OpenTV Shares (issued at (Pounds)10.43 per
     share or such other Pounds Sterling amount as the Purchaser's Accountants
     determine to be reasonable in the event of any consolidation, sub-division,
     stock split or reclassification or reduction of the share capital of the
     Purchaser or any rights issue, taking place after the date of this
     Agreement) or cash shall be issued or paid by the Purchaser to the Vendors
     (and, in

                                      126
<PAGE>

     respect of any New Open TV shares, the Purchaser shall deliver Open TV
     Certificates to the Vendors' Solicitors as soon as practicable).

6.   The Purchaser acknowledges the interests of the Vendors in the trading of
     the Group during the Period and that it is in the commercial interests of
     both the Purchaser and the Vendors to use all reasonable endeavours to
     ensure that the Group is in a position to maintain and increase
     profitability.  The Purchaser also acknowledges the interests of the
     Vendors in monitoring, inter alia, the financial performance, assets and
     obligations of the Group during the Earn-Out Period.  The Founders
     acknowledge that they will co-operate with the Purchaser and honour its
     reasonable requests to revise the forms of the Group's third-party
     contracts following Completion to assist the Purchaser to recognise the
     Group's revenues in its financial statements with respect to third-party
     contracts entered into following Completion pursuant to the US GAAP and
     accounting policies adopted by the Purchaser.


7.   The Purchaser covenants with the Vendors that during the Earn-Out Period it
     shall comply with following provisions of this paragraph 7:


7.1  the Purchaser shall procure that the Business is financed in accordance
     with the Business Plan;


7.2  the Purchaser will retain the beneficial ownership of the whole of the
     issued share capital of the Company; and


7.3  the Purchaser shall act in good faith towards the Vendors in relation to
     the Business insofar as its acts could affect the consideration payable to
     the Vendors under this agreement.


8.   The Purchaser shall procure that, except with the prior consent of Jasper
     Smith, during the Earn-Out Period:


8.1  except as otherwise set out in this Agreement, the Founders shall be
     entitled to participate in the management of the Group's operations;


8.2  the Group continues to operate the businesses carried on by it at
     Completion;

                                      127
<PAGE>

8.3  the nature and trading style of the Business as carried on at Completion is
     not changed;


8.4  no member of the Group enters into any transaction which is not on a
     commercial basis and on arms' length terms;


8.5  no member of the Group is required to provide or take credit, security,
     services or goods on bases which are materially less advantageous to it
     than those which are available on arms' length terms with third parties;


8.6  no member of the Group acquires or disposes of a subsidiary undertaking or
     a business;


8.7  no part of the undertaking or assets of any member of the Group is disposed
     of otherwise than in the ordinary course of its trading business and no
     gift is made or other arrangement or transaction entered in to by any
     member of the Group which could constitute a transaction at an undervalue
     (assuming the relevant member of the Group had at all relevant times been
     insolvent);


8.8  no member of the Group shall change its principal place of business from
     London;


8.9  no charge shall be levied on any member of the Group for services provided
     to it by the Purchaser (or any Associate of the Purchaser);


8.10 the rates of remuneration of employees of the Group are not increased
     except for increases in the ordinary course of business consistent with
     past practice or which, taken as a whole, are no greater than those awarded
     to employees of the Purchaser generally and, in any event, no greater than
     increases awarded to employees of comparable businesses;


8.11 the fees payable by members of the Group to auditors are not increased
     above the fees paid by members of the Group to their auditors for audit
     services for the year ended on 30 June 1999 (otherwise than for increases
     which are reasonably necessary to reflect inflation or to reflect the
     increased scope of the Business since 30 June 1999 or

                                      128
<PAGE>

     to reflect the fact that there is additional work involved as a consequence
     of the extension of the Group's accounting reference date to 31 December);


9.   No additional employees shall be employed by any member of the Group
     without the prior consent of Mr. Jasper Smith.


10.  The Purchaser undertakes to use all reasonable endeavours to operate the
     Group in the manner and based on the assumptions set out in the Business
     Plan PROVIDED THAT bandwidth costs may be treated as Costs of Sales rather
     than as R&D and Computer Costs.
