     shall, subject to Rule 3.2, vest in and become exercisable by the
     Optionholder up to the maximum numbers of A Option Shares set out below

                                       3

 
     Optionholder is a Relevant Employee on the following dates (each a "SERVICE

                                     =====                     =======
Total number of A Option Shares      5,000                   4,995,000

     On successive Service Dates, A Option Shares which have vested on previous
     Service Dates but in respect of which the A Option has not been exercised
     will continue to be exercisable by the Optionholder subject to the
     provisions of this Deed.

3.2  The Optionholder's rights to subscribe for A Option Shares under this Deed
     shall vest in and become exercisable by the Optionholder in full on a
     Change of Control (to the extent they have not vested in the Optionholder
     at such time) provided the Optionholder is a Relevant Employee on the date
     of such Change of Control.

     The B Option
     ------------

3.3  (a)  The Optionholder's rights to subscribe for B Option Shares under this
          Deed shall vest in and become exercisable by the Optionholder in full
          on the date of a Qualifying Trigger Event provided that the
          Optionholder is a Relevant Employee on such date. 

     (b)  For the purposes of this Rule 3.3 a "Qualifying Trigger Event" shall
          mean the issue of a certificate from the Company to the Optionholder
          certifying that:

          (i)    a public offering of the shares of the Company has realised (or
                 would have realised had the Investors elected to participate in
                 such offering) for each of the Investors cash amounts
                 equivalent to an internal rate of return in excess of 30% and a
                 return equal to or in excess of 2.5 times the sums subscribed
                 by the relevant Investor or Investors for shares of the Company
                 ("THE HURDLE RETURN");

          (ii)   a Qualifying Sale has realised for the Investor in question
                 cash amounts equivalent to the Hurdle Return; or

          (iii)  a Change of Control has realised for an Investor or Investors
                 cash amounts equivalent to the Hurdle Return.

                                       4

 
3.4  If any of the events described in Rule 3.3(b)(i), (ii) or (iii) shall occur
     but the Hurdle Return is not realised on such event, then the Company shall
     review, on the 28 February next following and on an annual basis until 28
     February 2002 thereafter, whether the Hurdle Return has been achieved. If
     the Company shall certify that the Hurdle Return has been achieved then the
     issue of such certificate shall be treated as a Qualifying Trigger Event
     and the Optionholder's rights to subscribe for B Option Shares shall vest
     in full and become exerciseable by the Optionholder on the date of such
     certificate provided that the Optionholder is a Relevant Employee on such
     date.

3.5  If the Optionholder is a Relevant Employee on 28th February 2002 in
     circumstances where a Qualifying Trigger Event has not occurred, the
     Company shall nevertheless certify to the Optionholder whether each of the
     Investors has achieved the Hurdle Return (Investment Gain for this purpose
     being calculated by reference to the value of the Company's equity share
     capital as at 28th February 2002). If the Company shall certify that the
     Hurdle Return has been achieved then the issue of such certificate shall be
     treated as a Qualifying Trigger Event and the Optionholder's rights to
     subscribe for the B Option Shares under this Deed shall vest in full and
     become exercisable by the Optionholder on the date of such certificate
     provided that the Optionholder is a Relevant Employee on such date.

3.6  If the Optionholder shall cease to be a Relevant Employee and is a Good
     Leaver before a Qualifying Trigger Event and between any of the dates
     mentioned in the first column below ("RELEVANT PERIODS") then the
     Optionholder shall be entitled to subscribe for such number of B Option
     Shares as are indicated in the second and third columns below on the
     occurrence of a Qualifying Trigger Event for the purposes of Rule 3.3, Rule
     3.4 or Rule 3.5:

RELEVANT PERIODS                         ORDINARY SHARES      PREFERENCE SHARES
(ALL DATES INCLUSIVE)

28 February 1998 to 27 February 1999          1,250               1,248,750
28 February 1999 to 27 February 2000          1,250               1,248,750
28 February 2000 to 27 February 2001          1,250               1,248,750
28 February 2001 to 28 February 2002          1,250               1,248,750
                                              -----               ---------
TOTALS                                        5,000               4,995,000

                                       5

 
     Rules 3.3, 3.4, or 3.5, as the case may be, shall apply mutatis mutandis to
     the question of whether a Qualifying Trigger Event has occurred.

3.7  If the Optionholder believes that the Company should have issued a
     certificate under Rules 3.3, 3.4, 3.5 or 3.6 but the Company disagrees,
     then the Optionholder or the Company may require the appointment of a
     suitably qualified independent third party ("THE EXPERT") to determine
     whether the criteria set out in Rule 3.3(b)(i), Rule 3.3(b)(ii), Rule
     3.3(b)(iii), Rule 3.4 or Rule 3.5 have been satisfied so that the Company
     should have issued a certificate that a Qualifying Trigger Event has
     occurred and that the Hurdle Return has been achieved. If the Expert shall
     demonstrate that a Qualifying Trigger Event has occurred or the Hurdle
     Return has been achieved then Rule 3.3(a) shall apply and his costs shall
     be borne by the Company. In any other case the costs of the Expert shall be
     borne by the Optionholder. The Expert shall act as an expert and not as an
     arbitrator and failing agreement between the Company and the Optionholder
     as to his identity he shall be appointed by the President for the time
     being of the Institute of Chartered Accountants in England and Wales.

C.   Provisions applicable to the Options
     ------------------------------------

3.8  In the event that the Optionholder shall cease to be a Relevant Employee in
     any circumstances, then the Optionholder (or his personal representatives
     in the case of his death or incapacity/disability) may exercise all or any
     part of the Options which have, at the time of the Optionholder's death or
     the termination of his employment, vested in the Optionholder as set out in
     Rules 3.1, 3.2, 3.3, 3.4 or 3.5 and, if the Optionholder is a Good Leaver
     before the Qualifying Trigger Event, then Rule 3.6 shall also apply. Any
     exercise of the Options pursuant to this Rule 3.8 must take place within 12
     months of the date of the Optionholder's death or in any other case within
     180 days from the date on which the Optionholder's employment terminated
     or, if any shares of the Company are at the date of termination listed on
     the London Stock Exchange, New York Stock Exchange or similar alternative
     exchange or market, 90 days from the date on which the Optionholder shall
     cease to be a Relevant Employee other than in the case of death. If such
     exercise would not be permitted under the Listing Rules of the London Stock
     Exchange (or the rules of any other relevant stock exchange) within these
     periods, the period for exercise shall commence on the date when such
     restriction would cease to apply.

3.9  Any rights to subscribe for the Option Shares which have not vested on the
     date on which the Optionholder ceases to be a Relevant Employee shall,
     subject to Rule 3.6, lapse and terminate automatically on the date of such
     cessation.

3.10 The Options shall lapse and terminate automatically insofar as they have
     not been exercised whether by the Optionholder or by his personal
     representatives and whether or not any rights to subscribe for Option
     Shares have vested at 5.30 pm (London time) on 28th February 2004.

3.11 It shall be a condition of the Options being granted that in the event of
     the Optionholder ceasing to be a Relevant Employee (for whatever reason) he
     shall not be entitled to any compensation whatsoever by reason of lapse of
     his rights

                                       6

 
     under the Options or by reason of any termination or alterations of rights
     or expectations thereunder.

4    Option to be personal to Optionholder
     -------------------------------------

4.1  The Option shall be personal to the Optionholder and shall not be capable
     of being transferred by him but may be exercised by an Optionholder's
     personal representatives subject to the provisions of this Deed in the
     event of the death or incapacity/disability of the Optionholder.

4.2  The Optionholder shall in no way sell, transfer, charge, mortgage, encumber
     or create any interest in favour of any third party over or in respect of
     the Option.

4.3  Except as permitted in Rule 4.1, if the Optionholder does or suffers to be
     done any act or thing whereby he is deprived of the legal or beneficial
     ownership of the Option then the Option shall lapse forthwith and the
     Company shall not knowingly permit the exercise of the Option.

5    Shares to be available and shares subscribed for to be subject to certain
     -------------------------------------------------------------------------
     restrictions
     ------------

5.1  The Company shall at all times keep available sufficient unissued Ordinary
     Shares and Preference Shares to satisfy the Options to the extent that they
     are then outstanding except to the extent that arrangements are made for
     such Options to the extent they are then outstanding to be satisfied by the
     transfer of Ordinary Shares and Preference Shares which have already been
     issued.

5.2  The Optionholder acknowledges that any Ordinary Shares and Preference
     Shares issued to him (or to his personal representatives) pursuant to the
     exercise of the Options are to be treated as Company Shares for the
     purposes of the Subscription Agreement dated 23rd January 1997 and entered
     into between the Optionholder, the Company and certain of the other
     shareholders of the Company (the "SUBSCRIPTION AGREEMENT") and accordingly
     are to be subject to clauses 2 and 3 of the Subscription Agreement. If so
     requested by the Company, the Optionholder agrees to execute an
     acknowledgement in favour of all parties to the Subscription Agreement in
     the terms set out in this clause.

6    Alteration of capital of the Company
     ------------------------------------

6.1  In the event of any capitalisation issue (other than a capitalisation issue
     to which section 249 Income and Corporation Taxes Act 1988 applies) or
     rights issue or any sub-division or consolidation of Ordinary Shares and
     Preference Shares or any reduction of the share capital of the Company, the
     nominal value and/or the number of Ordinary Shares and Preference Shares
     which are the subject of the Options and/or the Exercise Price thereof
     shall be adjusted by the Board in such manner as the Auditors shall confirm
     in writing as being in their opinion fair and reasonable.

6.2  Any such adjustment shall be made on the basis that the amount payable by
     the Optionholder on full exercise of the Options shall remain as nearly as
     possible

                                       7

 
     the same as (but shall not be greater than) it was before such event.
     Provided however that no such adjustment shall be made to the extent that
     it would result in a share being issued in consideration of the payment of
     an Exercise Price less than its nominal value and the Company shall use its
     best efforts to prevent the Exercise Price from being subject to such
     nominal value limitation.

6.3  If any adjustment falls to be made pursuant to Rule 6, the Company shall
     send to the Optionholder particulars of the revised basis of subscription
     or other exercise payment within 28 days after determination of the matter
     in question.

7    Procedure for exercise of the Option
     ------------------------------------

7.1  The Options shall be exercisable by notice in writing given to the Company
     by the Optionholder, or after his death or disability/incapacity by his
     personal representatives in accordance with this Deed, and (subject to Rule
     3) the Options may be exercised at one time or from time to time in respect
     of Shares the subject of the Options. Until exercised in full, the Options
     shall be exercisable over the remaining Shares which are the subject of the
     Options up to the maximum specified in Rule 2.2 and 2.3.

7.2  Any notice exercising any Option shall not be treated as valid unless and
     until a remittance from or on behalf of the Optionholder for the full
     amount of the Exercise Price for each of the Ordinary Shares and Preference
     Shares in respect of which the notice is given has been received by the
     Company.

7.3  Subject to:

     (a)  such consents as may be necessary, if any;

     (b)  compliance with the terms of the Options;

     (c)  if any of the shares subject to the Options are at the relevant time
          listed on the London Stock Exchange or permitted to be dealt in on the
          Alternative Investment Market, the Ordinary Shares in respect of which
          an Option has been exercised having been admitted to the Official List
          or permitted to be dealt in on the Alternative Investment Market (as
          the case may be) by the London Stock Exchange;

     the Company shall within 28 days after the later of the date of receipt of
     a notice exercising an Option and (if applicable) the receipt of the
     Auditors' confirmation under Rule 6 allot or procure the transfer of the
     Ordinary Shares and Preference Shares in respect of which such Option has
     been exercised to the Optionholder and deliver or procure the delivery of a
     definitive share certificate or other document or evidence of title in
     respect thereof to the Optionholder or his nominee or personal
     representative.

8    Rights of Shares and listing
     ----------------------------

8.1  Any Ordinary Shares and Preference Shares allotted on any exercise of an

     shares of the same class save as regards any rights attached thereto by
     reference to a record date prior to the date of such exercise and will be
     subject to all the provisions of the Articles of Association of the Company
     relating to voting, dividend, transfer, transmission and otherwise.
 
8.2  The Company will at its own cost and expense, if any shares the subject of
     an Option are at the relevant time listed on the London Stock Exchange or
     permitted to be dealt in on the Alternative Investment Market, apply to the
     London Stock Exchange for any shares of the same class in respect of which
     an Option has been exercised to be admitted to the Official List or
     permitted to be dealt in on the Alternative Investment Market (as the case
     may be) (except in cases where the relevant Option is satisfied by the
     transfer of shares which have already been admitted to the Official List or
     in respect of which permission has been granted for them to be dealt in on
     the Alternative Investment Market).  The Company will use its best efforts
     to cause the above results as to the London Stock Exchange or similar
     results if the shares of the Company are trading on the New York Stock
     Exchange or any similar alternative exchange or market.
